        Certain statements in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement or the accompanying prospectus include "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.

        Statements that refer to projections regarding the Acquisition (as defined below), our future financial performance, our anticipated growth and trends in our businesses, and other characterizations of future events or circumstances are forward-looking statements, and include, but are not limited to, statements relating to the timing, benefits and expectations regarding the Acquisition, overall volume trends, consumer preferences, pricing trends, industry forces, cost reduction strategies, anticipated results, anticipated synergies, anticipated cost savings, anticipated future debt issuances and financing requirements, expectations for funding future capital expenditures and operations, debt service capabilities, shipment levels and profitability, market share and the sufficiency of capital resources.

RISK FACTORS

        An investment in our notes involves a high degree of risk. Prior to making a decision about investing in our notes, you should carefully consider the following risks and uncertainties, as well as those discussed under the caption "Risk Factors" in the accompanying prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2015. If any of the risks described in this prospectus supplement or accompanying prospectus, or the risks described in any documents incorporated by reference in this prospectus supplement or the accompanying prospectus, actually occur, our business, prospects, financial condition or operating results could be harmed. In such case, the trading price of our notes could decline, and you may lose all or part of your investment.

Risks Relating to the Acquisition

We cannot predict when or if the Acquisition will close.

        The acquisition of the 58% equity interest and 50% voting interest of MillerCoors that we do not already own and the Miller brand portfolio outside of the U.S. and Puerto Rico is contingent upon a number of conditions beyond our control, including the closing of the ABI-SABMiller Transaction. The closing of the ABI-SABMiller Transaction is subject to conditions beyond our control, including, among other things, receipt of international and U.S. regulatory approvals. The Acquisition will also require us to obtain regulatory approvals in the U.S. and certain other jurisdictions. We are, therefore, unable to accurately predict when or if the Acquisition will close. If we are unable to close the Acquisition for any reason, we will not realize the potential benefits of the Acquisition, which may have a material adverse effect on our business prospects and the value of our notes.

We may not be able to realize anticipated cost synergies from the Acquisition.

        The success of the Acquisition will depend, in part, on our ability to realize anticipated cost synergies. Our success in realizing these cost synergies, and the timing of this realization, depends on the successful integration of our business and operations with the acquired business and operations. Even if we are able to integrate the acquired businesses and operations successfully, this integration may not result in the realization of the full benefits of the cost synergies of the Acquisition that we currently expect within the anticipated time frame or at all.

The Acquisition will subject us to significant additional liabilities and other risks.

        Following the Acquisition, we will be subject to substantially all the liabilities of MillerCoors, including, among others, significant pension liabilities. We will also be subject to the risks of the U.S. beer market to a much greater extent, and a significant majority of our overall business will be in mature, low growth beer markets, such as the U.S., Canada and the U.K. The Acquisition and subsequent integration process will be complex, costly, time-consuming and divert management's time and attention, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may be unable to obtain the regulatory approvals required to complete the Acquisition or, in order to do so, we may be required to satisfy material conditions or comply with material restrictions.

        In addition to the international and U.S. regulatory approvals needed to close the ABI-SABMiller Transaction, the consummation of the Acquisition is also subject to review and approval by regulatory authorities, including by the United States Department of Justice. We can provide no assurance that all required regulatory approvals will be obtained in order to consummate the Acquisition. We have agreed to take all actions necessary, and assist and cooperate in doing all things necessary, to avoid or eliminate any legal impediments to the Acquisition, including divesting of up to $4 billion in assets. There can be no assurance as to the cost, scope or impact on our business, results of operations,

S-14

Table of Contents

financial condition or prospects of the actions that may be required to obtain regulatory approvals. Any such divestitures or other actions could have a material adverse effect on the business of both us and MillerCoors and substantially diminish the synergies and other advantages which we expect from the Acquisition. In addition, we may not be able to effect any divestitures at an acceptable price or at all.

The Acquisition and the incurrence of indebtedness to fund the Acquisition may impact our financial position and subject us to additional financial and operating restrictions.

        We have raised significant capital to fund the Acquisition. We expect to incur a substantial amount of additional indebtedness in connection with this offering and the Concurrent Offerings. If we are unable to raise capital on acceptable terms in this offering or the Concurrent Offerings, we may need to rely on our Bridge Loan Agreement, which may result in substantially higher borrowing costs and a shorter maturity than those from other anticipated financing alternatives. In addition, ratings agencies may downgrade our credit ratings below their current investment grade levels as a result of additional indebtedness related to the Acquisition. A ratings downgrade could increase our costs of borrowing and harm our ability to finance the Acquisition on acceptable terms or refinance our debt in the future.

        The incurrence of indebtedness as contemplated by this offering, the Concurrent Offerings and the Term Loan Agreement will subject us to additional financial and operating covenants, which may limit our flexibility in responding to our business needs. If we are not able to maintain compliance with stated financial covenants or if we breach other covenants in any debt agreement, we could be in default under such agreement. Such a default may allow our creditors to accelerate the related indebtedness and may result in the acceleration of any other indebtedness to which a cross-acceleration or cross-default provision applies.

        Our overall leverage and terms of our financing could, among other things:

•

limit our ability to obtain additional financing in the future for working capital, capital expenditures and acquisitions;



•

make it more difficult to satisfy our obligations under the terms of our indebtedness;



•

limit our ability to refinance our indebtedness on terms acceptable to us or at all;



•

limit our flexibility to plan for and adjust to changing business and market conditions and increase our vulnerability to general adverse economic and industry conditions;



•

require us to dedicate a substantial portion of our cash flow to make interest and principal payments on our debt, thereby limiting the availability of our cash flow to fund future acquisitions, working capital, business activities, and other general corporate requirements; and



•

limit our ability to obtain additional financing for working capital, to fund growth or for general corporate purposes, even when necessary to maintain adequate liquidity, particularly if any ratings assigned to our debt securities by rating organizations were revised downward.

We face numerous risks associated with the potential acquisition and integration of the Miller brand portfolio outside the U.S. and Puerto Rico.

        The acquisition of the Miller brand portfolio outside of the U.S. and Puerto Rico may subject us to unknown expenses and liabilities due to our limited due diligence of the business, including, among other things, the absence of historical financial statements for this part of the business. The success of our acquisition of the Miller brand portfolio outside of the U.S. and Puerto Rico will depend, in part, on our ability to realize all or some of the anticipated synergies and other benefits from integrating its business with our existing businesses and operations. The integration process may be complex, costly

S-15

Table of Contents

and time-consuming as the Miller brand portfolio assets are in approximately 70 foreign countries. The difficulties of integrating the operations include, among others:

•

failure to implement our business plan for the combined business;



•

unanticipated issues in integrating manufacturing, logistics, information, communications and other systems;



•

possible inconsistencies in standards, controls, contracts, procedures and policies;



•

impacts of change in control and assignment provisions in contracts and agreements;



•

failure to retain key customers, suppliers and routes to market;



•

unanticipated changes in applicable laws and regulations;



•

failure to recruit and retain key employees to operate the combined business;



•

inherent operating risks in the business;



•

unanticipated issues, expenses and liabilities;



•

unfamiliarity with operating in many of the countries in which the international Miller brand portfolio operates;



•

difficulties related to the exit and wind-down in non-core Miller markets which we decide to exit post-closing;



•

reliance on a competitor, ABI, to provide transition services for this business;



•

failure to develop sustainable routes to market upon the expiration of ABI's transition services;



•

delays in obtaining any relevant regulatory approvals to operate the business in the countries in which the international Miller brand portfolio operates;



•

difficulty in fully separating the Miller brand portfolio from SABMiller's current brand portfolio; and



•

inability to perform satisfactory due diligence on the business prior to closing of the Acquisition.

        We may not be able to maintain the levels of revenue, earnings or operating efficiency that each of Molson Coors and the international Miller brand portfolio had achieved or might achieve separately. Although we have a downward purchase price adjustment if the unaudited U.S. GAAP EBITDA for the international Miller brand portfolio for the four quarters immediately prior to closing is below $70 million, such adjustment may not be adequate to protect us from the future harm of acquiring an underperforming or declining brand portfolio. In addition, we may not accomplish the integration of the international Miller brand portfolio smoothly, successfully or within the anticipated costs or timeframe. Moreover, the markets in which the international Miller brand portfolio operate may not experience the growth rates expected and any economic downturn affecting those markets could negatively impact the international Miller brand portfolio. These markets are in differing stages of development and may experience more volatility than expected or face more operating risks than in the more mature markets in which we have historically operated. If we experience difficulties with the integration process or if the international Miller brand portfolio or the markets in which it operates deteriorate, the potential cost savings, growth opportunities and other synergies of the acquisition of the Miller brand portfolio outside the U.S. and Puerto Rico may not be realized fully, or at all, or may take longer to realize than expected. In such case, our business, financial condition, results of operations and cash flows may be negatively impacted.

Table of Contents

If we are unable to consummate the Acquisition, our financial condition may materially suffer.

        If the Acquisition is not completed for any reason, our financial condition could materially suffer, including as a result of the following:

•

subject to certain reimbursement rights under the Purchase Agreement, the incurrence of significant costs related to the Acquisition without the associated benefits of completing the Acquisition, such as legal, accounting, filing, financial advisory, bridge and term loan financing and integration costs that have already been incurred or will continue to accrue up to the closing of the Acquisition. The amount of such operating expenses, fees and capital expenditures we incur in connection with the Acquisition will be based on a variety of factors but may be material;



•

increased dividend costs as a result of additional capital stock being issued without the associated benefits of completing the Acquisition;



•

if we complete the financing contemplated by this offering or the Concurrent Offerings, the incurrence of significant interest expense and potential redemption premiums with respect to such debt securities without the associated benefits of completing the Acquisition; and



•

potential disruption to our business and distraction of our workforce and management team.

We will incur substantial transaction fees and costs in connection with the Acquisition.

        We expect to incur a significant amount of non-recurring expenses in connection with the Acquisition, including legal, accounting, financial advisory and other expenses. Subject to certain reimbursement rights under the Purchase Agreement, many of these expenses are payable by us whether or not the Acquisition is completed. Additional unanticipated costs may be incurred following consummation of the Acquisition in the course of the integration of our businesses with that of MillerCoors and the international Miller brand portfolio. We cannot be certain that the elimination of duplicative costs or the realization of other efficiencies related to the integration of the businesses will offset the transaction and integration costs in the near term, or at all.

The Acquisition will significantly increase our goodwill and other intangible assets.

        We have a significant amount, and following the Acquisition will have an additional amount, of goodwill and other intangible assets on our consolidated financial statements that are subject to impairment based upon future adverse changes in our business or prospects. Our current estimate of the amount of goodwill and other intangible assets on our consolidated financial statements that would be subject to impairment as of March 31, 2016 on a pro forma basis is $22.8 billion (as reflected in, and subject to the uncertainties described below in our unaudited pro forma condensed combined financial information as of March 31, 2016). The impairment of any goodwill and other intangible assets may have a negative impact on our consolidated results of operations.

The unaudited pro forma condensed combined financial information included or incorporated by reference in this prospectus supplement and the accompanying prospectus only gives effect to the acquisition of MillerCoors and is presented for illustrative purposes only and may not be an indication of our financial condition or results of operations after giving effect to the Acquisition.

        The unaudited pro forma condensed combined financial information included or incorporated by reference in this prospectus supplement and the accompanying prospectus is presented for illustrative purposes only, is based on various adjustments, assumptions and preliminary estimates and may not be an indication of our financial condition or results of operations following the Acquisition, as applicable, for several reasons. See "Summary—Summary Historical Consolidated and Pro Forma Financial Data" included in this prospectus supplement. In particular, the unaudited pro forma condensed combined

S-17

Table of Contents

financial information contained herein does not give effect to the acquisition of the international Miller brand portfolio outside of the United States and Puerto Rico because of a lack of information and financial statements regarding its historical operations. Additionally, the estimated purchase price allocation for the Acquisition is preliminary and may be materially different once we obtain access to additional information. Our actual financial condition and results of operations following the Acquisition, due to the exclusion of the international Miller brand portfolio outside of the United States and Puerto Rico or otherwise, may not be consistent with, or evident from, this unaudited pro forma condensed combined financial information. In addition, the assumptions used in preparing the unaudited pro forma condensed combined financial information may not prove to be accurate, and other factors not accounted for in the unaudited pro forma condensed combined financial information may affect our financial condition or results of operations following the Acquisition.

Risks Related to the Notes and this Offering

The notes are subject to prior claims of our secured creditors and the creditors of our non-guarantor subsidiaries, and if a default occurs we may not have sufficient funds to fulfill our obligations under the notes.

        The notes are our unsubordinated general obligations, ranking equally with our other unsubordinated indebtedness and liabilities but effectively subordinated to any secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to the debt and other liabilities of our non-guarantor subsidiaries. The indenture governing the notes permits us and our subsidiaries to incur secured debt under specified circumstances. If we incur any secured debt, our assets and the assets of our subsidiaries securing such debt will be subject to prior claims by our secured creditors. In the event of our bankruptcy, liquidation, reorganization or other winding up, assets that secure debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in our remaining assets ratably with all of our unsecured and unsubordinated creditors, including our trade creditors. Additionally, our right to receive assets from any of our non-guarantor subsidiaries upon its bankruptcy, liquidation or reorganization, and the right of holders of the notes to participate in those assets, is structurally subordinated to claims of that subsidiary's creditors, including trade creditors.

        If we incur any additional obligations that rank equally with the notes, including trade payables, the holders of those obligations will be entitled to share ratably with the holders of the notes in any proceeds distributed to unsecured and unsubordinated creditors upon our insolvency, liquidation, reorganization, dissolution or other winding up. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all of these creditors, all or a portion of the notes then outstanding would remain unpaid.

        As of March 31, 2016, after giving effect to this offering and the Concurrent Offerings and the incurrence of indebtedness pursuant to Term Loan Agreement to finance the Acquisition, we would have had outstanding indebtedness of approximately $12.6 billion that ranks equally with the notes and no secured indebtedness outstanding. As of March 31, 2016 (but after giving effect to the removal of Molson Coors Brewing Company UK Limited, Golden Acquisition and Molson Coors Holdings Ltd. as subsidiary guarantors on May 13, 2016), our non-guarantor subsidiaries would have had approximately $63.5 million of outstanding indebtedness, excluding $5.1 billion of intercompany debt.

The notes will not be guaranteed by all of our subsidiaries and will be structurally subordinated to the debt of our non-guarantor subsidiaries, which means that creditors of these non-guarantor subsidiaries will be paid from the assets of those entities before holders of the notes would have any claims to those assets.

        The notes will not be guaranteed by all of our subsidiaries and will be structurally subordinated to the debt of our non-guarantor subsidiaries, which means that creditors of these non-guarantor

Table of Contents

subsidiaries will be paid from the assets of those entities before holders of the notes would have any claims to those assets. Although the notes will be fully and unconditionally guaranteed on a senior unsecured basis by certain of our existing and future subsidiaries, they will not be guaranteed by our other subsidiaries. For financial information regarding the Guarantors please see note 19 to our consolidated financial statements included in our Current Report on Form 8-K as filed on June 28, 2016 for the year ended December 31, 2015, which is incorporated by reference into this prospectus supplement and the related prospectus. The notes will be effectively subordinated to all debt and other liabilities, including trade debt and preferred share claims, of our non-guarantor subsidiaries. In addition, although they will not guarantee the notes, these non-guarantor subsidiaries may, in certain circumstances, guarantee our future debt obligations to the extent the guarantee would not constitute a fraudulent conveyance, result in adverse tax consequences to us or violate applicable local law. Furthermore, certain of these non-guarantor subsidiaries have guaranteed the obligations of certain non-U.S. borrowers under our revolving multi-currency credit facilities.

We are a holding company and depend on our subsidiaries to satisfy our cash needs, including to make payments on the notes.

        Our operations are substantially conducted through our subsidiaries. As a result, the cash flow and the consequent ability to service our indebtedness, including the notes, is in large part dependent upon the earnings of our subsidiaries and the distribution of those earnings to us or upon the payment of funds to us by those subsidiaries. Our subsidiaries are separate and distinct legal entities and, except for our subsidiaries that guarantee the notes, have no obligation, contingent or otherwise, to pay any amounts due pursuant to the notes or to make funds available to us, whether by dividends, loans or other payments, except to the extent that there are enforceable inter-company obligations created in the future. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to contractual or statutory restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations.

        In addition, our ability to repatriate cash generated by our foreign operations or borrow from our foreign subsidiaries may be limited by tax, foreign exchange or other laws. Foreign tax laws may affect our ability to repatriate cash from foreign subsidiaries. Foreign earnings may be subject to withholding requirements for foreign taxes. Cash we hold in foreign entities may become subject to exchange controls that prevent such cash from being converted into other currencies, including U.S. dollars. If our ability to repatriate cash generated by our foreign operations or borrow from our foreign subsidiaries is limited by tax, foreign exchange or other laws, our ability to make payments on our debt, including amounts due under the notes, would be harmed.

The indenture does not limit the amount of unsecured indebtedness that we and our subsidiaries may incur.

        The indenture under which the notes will be issued does not limit the amount of unsecured indebtedness that we and our subsidiaries may incur. In addition, the indenture will permit us to incur additional secured indebtedness under specified circumstances. The indenture does not contain any financial covenants or other provisions that would afford the holders of the notes any substantial protection in the event we participate in a highly leveraged transaction.

Changes in our credit ratings may adversely affect the value of the notes.

        We cannot provide assurance as to the credit ratings that may be assigned to the notes or that any such credit ratings will remain in effect for any given period of time or that any such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency's judgment, circumstances warrant such an action. Further, any such ratings will be limited in scope and will not address all material risks relating to an investment in the notes, but rather will reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could adversely affect the market value of the notes and increase our corporate borrowing costs.

Failure to comply with our debt covenants or a deterioration in our credit rating could have an adverse effect on our ability to obtain future financing at competitive rates and/or our ability to refinance our existing indebtedness.

        Under the terms of each of our credit facilities, we must comply with certain restrictions. These include restrictions on priority indebtedness (certain threshold percentages of secured consolidated net tangible assets), leverage thresholds, liens, and restrictions on certain types of sale lease-back transactions and transfers of assets. Failure to comply with these restrictions or maintain our credit rating may result in issues with our current financing structure and potential future financing requirements. A deterioration in our credit rating could also affect our ability to obtain future financing or refinance our current debt, as well as increase our borrowing rates, which could have an adverse effect on our business and financial results.

Credit ratings assigned to the notes may not reflect all risks of an investment in the notes.

        The credit ratings assigned to the notes reflect the rating agencies' current assessment of our ability to make payments on the notes when due. Consequently, real or anticipated changes in any of these credit ratings will generally affect the market value of the notes. These credit ratings, however, may not reflect the potential impact of risks related to the structure, market or other factors related to the value of the notes.

We may be unable to refinance our indebtedness.

        We may need to refinance all or a portion of our indebtedness, including the notes, before maturity. We cannot assure you that we will be able to refinance any of our indebtedness, on commercially reasonable terms or at all. There can be no assurance that we will be able to obtain sufficient funds to enable us to repay or refinance our debt obligations on commercially reasonable terms, or at all.

We may not be able to repurchase the notes upon a Change of Control Triggering Event.

        If a Change of Control Triggering Event occurs, unless we have exercised our right to redeem the notes, we will be required to make an offer to repurchase the notes in cash at the redemption prices described in this prospectus supplement. However, we may not be able to repurchase the notes upon a Change of Control Triggering Event because we may not have sufficient funds to do so. We may also be required to offer to repurchase certain of our other debt upon a change of control and such event may give rise to an event of default under our credit facilities. In addition, agreements governing indebtedness incurred in the future may restrict us from repurchasing the notes in the event of a Change of Control Triggering Event. Any failure to repurchase properly tendered notes would constitute an event of default under the indenture governing the notes, which could, in turn, cause an acceleration of our other indebtedness. See "Description of the Notes—Repurchase Upon Change of Control Triggering Event."

        We can enter into transactions, like recapitalizations, reorganizations, transactions with "permitted parties" (as defined in "Description of the Notes—Repurchase Upon Change of Control Triggering Event") and other highly leveraged transactions, that do not constitute a change of control but that could adversely affect the holders of the notes. The change of control provision contained in the indenture may not necessarily afford you protection in the event of certain important corporate events, including a reorganization, restructuring, merger or other similar transaction involving us that may adversely affect you, because such corporate events may not involve a shift in voting power or beneficial ownership or, even if they do, may not constitute a "Change of Control" as defined in the indenture. The indenture will not contain provisions that would require the Company to offer to

S-20

Table of Contents

repurchase or redeem the notes in the event of a reorganization, restructuring, merger, recapitalization or similar transaction.

We may be unable to redeem the notes in the event of a special mandatory redemption.

        The notes will be subject to a special mandatory redemption in the event that (i) we do not complete the Acquisition on or prior to November 11, 2016 (or, if pursuant to Purchase Agreement the Termination Date is automatically extended, the date (not later than 18 months after November 11, 2015) to which the Termination Date is so extended), or (ii) if, prior to such date, we notify the Trustee in writing that we will not pursue the Acquisition. The special mandatory redemption price will be equal to 101% of the aggregate principal amount of the applicable series of notes, plus accrued and unpaid interest from the issue date of the notes, up to, but excluding, the date of such special mandatory redemption. See "Description of the Notes—Special Mandatory Redemption." We are not obligated to place the proceeds of the offering of the notes in escrow prior to the closing of the Acquisition or to provide a security interest in those proceeds, and there are no other restrictions on our use of these proceeds during such time. Accordingly, we will need to fund any special mandatory redemption using proceeds that we have voluntarily retained or from other sources of liquidity, including by exercising certain reimbursement rights under the Purchase Agreement. In the event of a special mandatory redemption, we may not have sufficient funds to purchase all of the notes.

In the event of a special mandatory redemption, holders of the notes may not obtain their expected return on such notes.

        If we redeem the notes pursuant to the special mandatory redemption provisions, you may not obtain your expected return on the notes and may not be able to reinvest the proceeds from such special mandatory redemption in an investment that results in a comparable return. In addition, as a result of the special mandatory redemption provisions of the notes, the trading prices of the notes may not reflect the financial results of our business or macroeconomic factors. You will have no rights under the special mandatory redemption provisions if the Acquisition closes within the prescribed timeframe, nor will you have any right to require us to repurchase your notes if, between the closing of this offering and the closing of the Acquisition, we experience any changes (including any material changes) in our business or financial condition, or if the terms of the Purchase Agreement change, including in material respects.

The notes of each series will be a new class of securities for which there is no established public trading market, and no assurance can be given as to:

•

the liquidity of any such market that may develop;



•

the ability of holders of the notes to sell their notes; or



•

the prices at which the holders of the notes would be able to sell their notes.

        If such markets were to exist, the notes could trade at prices that may be higher or lower than their principal amounts or purchase prices, depending on many factors, including:

•

prevailing interest rates and the markets for similar securities;



•

our credit rating;



•

the terms related to redemption or repurchase of the notes;



•

the amount of our outstanding indebtedness;



•

the interest of securities dealers in making a market;



•

the remaining time to maturity of the notes;

S-21

Table of Contents

•

changes to the Acquisition terms or problems or delays in closing the Acquisition;



•

general economic conditions; and



•

our financial condition, historic financial performance and future prospects.

        The underwriters have advised us that they currently intend to make a market in the notes of each series. However, the underwriters are not obligated to do so and any underwriter may discontinue its market making activities at any time without notice.

        We intend to apply for the notes to be listed and admitted to trading on the New York Stock Exchange. We cannot assure you that such application will be approved. Although no assurance is made as to the liquidity of the notes as a result of the admission to trading on the New York Stock Exchange, failure to be approved for listing on or the delisting of the notes from the New York Stock Exchange may have a material effect on a holder's ability to resell the notes in the secondary market. The liquidity of the trading market in the notes and the market prices quoted for the notes may be adversely affected by changes in the overall market for this type of securities and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a consequence, an active trading market may not develop for the notes, you may not be able to sell the notes, or, even if you can sell the notes, you may not be able to sell them at an acceptable price.

The notes may not become, or remain, listed on the New York Stock Exchange.

        Although we have agreed to make an application to have the notes listed and admitted to trading on the New York Stock Exchange, we cannot assure you that the notes will become, or remain, listed. The listing application will be subject to approval by the New York Stock Exchange. If such a listing is obtained, we have no obligation to maintain such listing and we may delist the notes at any time. Although no assurance can be made as to the liquidity of the notes as a result of listing on the New York Stock Exchange, failure to be approved for listing or the delisting of the notes from the New York Stock Exchange may have a material adverse effect on a holder's ability to resell notes in the secondary market.

The guarantees of the notes may not be enforceable in certain circumstances.

        The Trustee is entitled, subject to the terms of the indenture governing the notes and provided that an event of default has occurred and is continuing, to seek redress from each Guarantor for the guaranteed indebtedness. However, there can be no assurance that the Trustee will, or will be able to, effectively enforce the guarantees or that the assets of the Guarantors, together with those of the Company, will be sufficient to satisfy our obligations under the notes.

        The creditors of the Company and the Guarantors could challenge the issuances of any of the notes or the related guarantees and any related security as fraudulent transfers, conveyances or preferences, transfers at under value or on other grounds under applicable law. A court could void the obligations under the notes or any guarantee and any related security or take other actions detrimental to the holders of the notes if, among other things, it were to determine that we or the applicable Guarantor:

•

issued the notes or guarantee or related security with the intent to prefer, defeat, hinder, delay or defraud its existing or future creditors;



•

received less than reasonably equivalent value or fair consideration in return for issuing the notes or the guarantee or related security;



•

was insolvent or rendered insolvent by reason of issuing the notes or the guarantee; or

S-22

---

Table of Contents

•

acted in an oppressive manner, unfairly prejudicial to or unfairly disregarded the interests of any stakeholder or other interested party.

        To the extent a court voids a guarantee and any related security as a fraudulent transfer, preference or conveyance or holds it unenforceable for any other reason, holders of the notes would cease to have any direct claim against the Guarantor that delivered the guarantee. If a court were to take this action, the Guarantor's assets would be applied first to satisfy the Guarantor's liabilities, including trade payables, and preferred stock claims, if any, before any payment in respect of the guarantee could be made. A Guarantor's remaining assets may not be sufficient to satisfy the claims of holders of the notes relating to any voided portions of the guarantees and any related security.

An investment in the notes by a purchaser whose home currency is not euros entails significant risks.

        All payments of interest on and the principal of the notes and any redemption price for the notes will be made in euros. An investment in the notes by a purchaser whose home currency is not euros entails significant risks. These risks include the possibility of significant changes in rates of exchange between the holder's home currency and euro and the possibility of the imposition or subsequent modification of foreign exchange controls. These risks generally depend on factors over which we have no control, such as economic, financial and political events and the supply of and demand for the relevant currencies. In the past, rates of exchange between the euros and certain currencies have been highly volatile, and each holder should be aware that volatility may occur in the future. Fluctuations in any particular exchange rate that have occurred in the past, however, are not necessarily indicative of fluctuations in the rate that may occur during the term of the notes. Depreciation of the euros against the holder's home currency would result in a decrease in the effective yield of the notes below its coupon rate and, in certain circumstances, could result in a loss to the holder. Investing in the notes by U.S. investors may also have important tax consequences. See "Certain Material U.S. Federal Income Tax Considerations" for more detail.

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

        The notes and the indenture governing the notes will be governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the notes would be required to render the judgment in euros. The judgment would be converted into U.S. dollars, however, at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the notes, investors whose home currency is not euros would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time. A U.S. federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the notes would apply the foregoing New York law. To the extent that a judgment is ordered in U.S. dollars, an investor would be subject to exchange risk on the amount they receive in euros due to variation in the exchange rate between the time of judgment and the time of collection.

        In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The indenture includes an indemnity by the Company against a deficiency due to any such judgment, but there can be no assurance that such indemnity will be enforced. The date used to determine the rate of conversion of euros into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

Trading in the clearing systems is subject to minimum denomination requirements.

        The notes will be issued only in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. It is possible that the clearing systems may process trades which could result

S-23

---

Table of Contents

in amounts being held in denominations smaller than the minimum denominations. If definitive notes are required to be issued in relation to such notes in accordance with the provisions of the relevant global notes, a holder who does not have the minimum denomination or an integral multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

The notes permit us to make payments in U.S. dollars if we are unable to obtain euro.

        If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars at the most recently available market exchange rate for euro. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes.

The proposed financial transactions tax ("FTT") may negatively affect holders of the notes.

        On February 14, 2013, the European Commission published a proposal (the "Commission's Proposal") for a Directive for a common FTT in Belgium, Germany, Estonia, Greece, Spain, France, Italy, Austria, Portugal, Slovenia and Slovakia (with the potential exception of Estonia which has recently indicated it no longer supports the proposal, the "FTT Participating Member States"). The Commission's Proposal has very broad scope and could, if introduced in its current form, apply to certain dealings in the notes (including secondary market transactions) in certain circumstances. The issuance and subscription of the notes should, however, be exempt.

        Under the Commission's Proposal, the FTT could apply in certain circumstances to persons both within and outside the FTT Participating Member States. Generally, it would apply to certain dealings in the notes where at least one party is a financial institution, and at least one party is established in a FTT Participating Member State. A financial institution may be, or may be deemed to be, "established" in a FTT Participating Member State in a broad range of circumstances, including (a) by transacting with a person established in a FTT Participating Member State or (b) where the financial instrument which is subject to the dealings is issued in a FTT Participating Member State.

        However, the FTT proposal remains subject to negotiation between the participating Member States. It may therefore be altered prior to any implementation. The EU have set a deadline for agreeing a framework for the end of June 2016, however the Commission's Proposal's ultimate implementation (and the timing thereof) remains unclear. Additional EU Member States may decide to participate. Prospective holders of the notes are advised to seek their own professional advice in relation to the FTT.

The notes will initially be held in book-entry form and therefore investors must rely on the procedures of the relevant clearing systems to exercise any rights and remedies.

        The notes will initially only be issued in global certificated form and held through Euroclear and Clearstream. Interests in the global notes will trade in book-entry form only, and notes in definitive registered form will be issued in exchange for book-entry interests only in very limited circumstances. Owners of book-entry interests will not be considered owners or holders of notes. The common depositary for Euroclear and Clearstream, or its nominee, will be the sole registered holder of the global notes representing the notes. Payments of principal, interest and other amounts owing on or in respect of the global notes representing the notes will be made to the paying agent for the notes, which

S-24

---

Table of Contents

will make payments to Euroclear and Clearstream. Thereafter, these payments will be credited to participants' accounts that hold book-entry interests in the global notes representing the notes and credited by such participants to indirect participants. After payment to the common depositary for Euroclear and Clearstream, we will have no responsibility or liability for the payment of interest, principal or other amounts to the owners of book-entry interests. Accordingly, if investors own a book-entry interest, they must rely on the procedures of Euroclear and Clearstream, and if investors are not participants in Euroclear and Clearstream, they must rely on the procedures of the participant through which they own their interest, to exercise any rights and obligations of a holder of notes under the indenture governing the notes.

        Unlike the holders of the notes themselves, owners of book-entry interests will not have the direct right to act upon our solicitations for consents, requests for waivers or other actions from holders of the notes. Instead, if an investor owns a book-entry interest, they will be permitted to act only to the extent they have received appropriate proxies to do so from Euroclear and Clearstream. The procedures implemented for the granting of such proxies may not be sufficient to enable such investor to vote on a timely basis.

        Similarly, upon the occurrence of an event of default under the indenture governing the notes, unless and until definitive registered notes are issued in respect of all book-entry interests, if investors own book-entry interests, they will be restricted to acting through Euroclear and Clearstream. The procedures to be implemented through Euroclear and Clearstream may not be adequate to ensure the timely exercise of rights under the Notes. See "Description of the Notes—Book-Entry, Clearance and Settlement."

Risks Related to our Business

        For risks related to our business, please see our Annual Report on Form 10-K for the year ended December 31, 2015, which is incorporated by reference herein, as well as the information set out below.

The vote in the U.K. to leave the European Union could adversely affect us.

        Nearly 11% of our pro forma net sales in 2015 came from the U.K., which is our largest market in Europe. In a referendum held on June 23, 2016, a majority of voters in the U.K. voted in favor of the U.K. leaving the European Union. At this time, we are not able to predict the impact that the result of this vote will have on the economy in Europe, including in the U.K., or on GBP, euro or other European exchange rates. Weakening of economic conditions or economic uncertainties tend to harm the beer business, and if such conditions emerge in the U.K. or in the rest of Europe, it may have a material adverse effect on our Europe segment. In addition, any significant weakening of the GBP or the euro to the USD will have an adverse impact on our European revenues as reported in USD due to the importance of U.K. and European Union sales.

        We intend to use all the net proceeds of the offering as partial consideration for the Acquisition. Prior to the closing of the Acquisition, we intend to invest the net proceeds from this offering in U.S. government securities, short-term certificates of deposit, cash equivalents, money market funds or other short-term investments or demand deposit accounts. The net proceeds from this offering will not be deposited into an escrow account and you will not receive a security interest in such proceeds.

        The notes will be subject to a special mandatory redemption in the event that (i) we do not complete the Acquisition on or prior to November 11, 2016 (or, if pursuant to the Purchase Agreement the Termination Date is automatically extended, the date (not later than 18 months after November 11, 2015) to which the Termination Date is so extended), or (ii) if, prior to such date, we notify the Trustee in writing that we will not pursue the Acquisition. The special mandatory redemption price will be equal to 101% of the aggregate principal amount of the applicable series of notes, plus accrued and unpaid interest from the issue date of the notes, up to, but excluding, the date of such special mandatory redemption.

DESCRIPTION OF THE NOTES

        This section describes the specific financial and legal terms of the notes (as defined below). References to "we," "us" or the "Company" in this Description of the Notes are references to Molson Coors Brewing Company and not any of its subsidiaries. The following is a summary of the material terms of each series of the notes offered hereby and does not purport to be complete. Reference is made to the indenture (defined below) for the full text of the terms of each series of the notes, a copy of which is available from us upon request as described under the caption "Information Incorporated by Reference." The terms of the notes include those stated in the indenture and those made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

        On November 11, 2015, we entered into a purchase agreement (the "Purchase Agreement") with Anheuser-Busch InBev SA/NV ("ABI") to acquire, contingent upon the acquisition of SAB Miller plc ("SAB Miller") by ABI, all of SAB Miller's interest in MillerCoors LLC ("MillerCoors") and all the trademark contracts and other assets primarily related to the Miller brand portfolio outside the United States of America and Puerto Rico (such acquisition, the "Acquisition"). The notes will be subject to a special mandatory redemption in the event that (i) we do not complete the Acquisition on or prior to November 11, 2016 (or if, pursuant to the Purchase Agreement the Termination Date (as defined therein) is automatically extended, the date (not later than 18 months after November 11, 2015) to which the Termination Date is so extended), or (ii) if, prior to such date, we notify the trustee in writing that we will not pursue the Acquisition.

        The special mandatory redemption price for each series of the notes is equal to 101% of the aggregate principal amount of such series, plus accrued and unpaid interest on such series to, but excluding, the Special Mandatory Redemption Date (as defined below).

General

        Each series of notes offered hereby will be issued under an indenture, to be dated as of                        , 2016, among the Company, the Guarantors and Deutsche Bank Trust Company Americas, as trustee and as paying agent, as supplemented by a supplemental indenture, to be dated as of                        , 2016, between us, the Guarantors and the trustee and paying agent (as supplemented, the "indenture"), in an aggregate principal amount of €         million. The        % senior notes due 20    will be issued in an initial aggregate principal amount of €            and will mature on                        , 20    (the "20    notes"). The         % senior notes due 20    will be issued in an initial aggregate principal amount of €            and will mature on                        , 20    (the "20    notes"). The 20    notes and the 20    notes are collectively referred to herein as the "notes." Each series of notes will be issued only in fully registered form without coupons in minimum denominations of €100,000 and integral multiples of €1,000 above that amount. No service charge will be made for any transfer or exchange of the notes, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. The notes will not be entitled to any sinking fund.

        Interest will accrue on the 20    notes and the 20    notes at the applicable rate per annum shown on the cover of this prospectus supplement from the issue date of the notes, or from the most recent date to which interest has been paid or provided for, and will be payable in cash annually in arrears on            of each year, beginning on                        , 2017, to the persons in whose names the notes are registered in the security register at the close of business on the            preceding the relevant interest payment date, except that interest payable at maturity shall be paid to the same persons to whom principal of such notes is payable. Interest on the notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes (or                        , 2017 if no interest has been paid on the notes), to but excluding the next scheduled interest payment date. This

payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. Principal and interest will be payable, and the notes will be transferable or exchangeable, at the office or offices or agency maintained by us for this purpose.

        If any interest payment date is not a Business Day, we will pay interest on the next day that is a Business Day as if payment were made on the date such payment was due, and no interest will accrue on the amounts so payable for such delay. A Business Day is a day other than a Saturday, Sunday or other day on which commercial banks in New York City or London are authorized or required by law to close, or on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, is closed.

        We will initially appoint the trustee at its corporate trust office as a paying agent, transfer agent and registrar for the notes. We will cause each transfer agent to act as a co-registrar and will cause to be kept at the office of the registrar a register in which, subject to such reasonable regulations as we may prescribe, we will provide for the registration of the notes and registration of transfers of the notes. We may vary or terminate the appointment of any paying agent or transfer agent, or appoint additional or other such agents or approve any change in the office through which any such agent acts. We will provide you with notice of any resignation, termination or appointment of the trustee or any paying agent or transfer agent, and of any change in the office through which any such agent will act.

        The notes will be unsecured and unsubordinated obligations of the Company and will rank pari passu with its other unsecured and unsubordinated debt, including the Existing Notes (defined below) and U.S. borrowings under our credit facilities.

        We may issue additional securities under the indenture from time to time in one or more other series, which may have terms and conditions that differ from those set forth herein. The 20    notes and the 20    notes will each constitute a separate series of securities under the indenture. We are initially offering the notes in the aggregate principal amount of €            . In addition, we may, without the consent of the holders of any series of the notes, issue additional notes having the same terms and conditions in all respects as any series of the notes being offered hereby, except for the applicable issue date and the issue price. Any such additional notes having such similar terms, together with the relevant series of the notes offered by this prospectus supplement, will be treated as a single series of securities under the indenture, provided that if any such additional notes are not fungible with the existing notes for United States federal income tax purposes, such additional notes will have separate ISIN, CUSIP and Common Code numbers, as applicable.

        The notes and other securities of other series under the indenture will vote together as a single class in many circumstances. To the extent that any securities are issued under the indenture and denominated in a currency other than U.S. dollars, the principal amount of the notes and such other securities for purposes of any act, consent or waiver under the indenture shall be determined as the dollar equivalent thereof, converted based on the spot rate (as determined by us in our discretion) at 11:00 a.m. Eastern time on the Business Day before the record date for such act, waiver or consent (or, if there is no such record date, the date when such act, consent or waiver is taken).

Guarantees

        The notes will be jointly and severally guaranteed on a full and unconditional senior unsecured basis initially by Molson Coors International LP, Molson Canada 2005, Molson Coors International General, ULC, Molson Coors Callco ULC, Coors International Holdco, ULC, Coors Brewing Company, Molson Coors Holdco Inc., CBC Holdco LLC, MC Holding Company LLC, CBC Holdco 2 LLC and Newco3, Inc. (all of which are wholly owned directly or indirectly by the Company and, upon consummation of the Acquisition, MillerCoors. The Guarantors will fully and unconditionally guarantee the payment of all of the principal of, and any premium and interest, if any, on, the notes when due, whether at maturity or otherwise. Each guarantee will be limited as necessary to prevent

S-31

such guarantee from being rendered voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each of these entities will also guarantee our obligations under our credit facilities and our Existing Notes.

        Each Guarantor that makes a payment under its guarantee will be entitled to a contribution from each other Guarantor in an amount equal to such other Guarantor's pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP. If a guarantee were to be rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the applicable Guarantor and, depending on the amount of such indebtedness, a Guarantor's liability on its guarantee could be reduced to zero.

        In addition, the Company will cause each of its Subsidiaries that guarantees Senior Debt of the Company under (i) the Company's then-existing primary credit facility, (ii) the 2.25% Notes due 2018 guaranteed by the Company, the 2.75% Notes due 2020 guaranteed by the Company, the 2.0% Notes due 2017 issued by the Company, the 3.5% Notes due 2022 issued by the Company, the 5.0% Notes due 2042 issued by the Company or the 3.95% Series A Notes due 2017 (the "Existing Notes"), or (iii) any senior unsecured notes issued by the Company in future capital markets transactions ("Additional Debt"), after the first original issue date of the notes to, within 30 days of any of the events listed in clauses (i), (ii), and (iii) immediately above, to execute and deliver to the trustee a supplemental indenture pursuant to which such Subsidiary will guarantee payment of each series of the notes on the same terms and conditions as the original guarantees from the initial Guarantors.

        A Guarantor will be automatically released and relieved from all its obligations under its guarantee in the following circumstances:

        (a)   upon the sale or other disposition (including by way of consolidation or merger), in one transaction or a series of related transactions, of at least a majority of the total voting power of the capital stock or other interests of such Guarantor (other than to the Company or any of its Subsidiaries), as permitted under the indenture;

        (b)   upon the sale or disposition of all or substantially all the assets of such Guarantor (other than to the Company or any of its Subsidiaries), as permitted under the indenture; or

        (c)   if at any time when no default has occurred and is continuing with respect to the notes, such Guarantor no longer guarantees (or which guarantee is being simultaneously released or will be immediately released after the release of the Guarantor) the Debt of the Company under (i) the Company's then-existing primary credit facility, (ii) the Existing Notes or (iii) any Additional Debt.

        "Senior Debt" means, with respect to any Person, Debt of such Person, whether outstanding on the date of the indenture or thereafter incurred unless, in the instrument creating or evidencing the same or pursuant to which the same is outstanding, it is provided that such obligations are subordinate in right of payment to the notes; provided, however, that Senior Debt shall not include (1) any Debt of such Person owing to any affiliate of the Company; or (2) any Debt of such Person (and any accrued and unpaid interest in respect thereof) which is subordinate or junior in any respect to any other Debt of such Person.

Optional Redemption

        We may, at our option, at any time and from time to time redeem all or any portion of any series of the notes at any time prior to the applicable Par Call Date (as set forth in the table below) on not

S-32

Table of Contents

less than 30 nor more than 60 days' prior notice mailed to registered holders of the notes to be redeemed at a redemption price equal to the greater of:

•

100% of the principal amount of the notes being redeemed; and



•

the sum of the present values of the redemption price of the notes on the applicable Par Call Date and the remaining scheduled payments of interest on the series of notes being redeemed as if the notes were redeemed on the applicable Par Call Date (exclusive of interest accrued to the date of redemption) discounted to the redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)) computed using a discount rate equal to the applicable Bund Rate (or, if greater than such Bund Rate, zero) plus (i)                           basis points in the case of the 20    notes and (ii)             basis points in the case of the 20    notes,

in each case, plus accrued and unpaid interest on the principal amount of such notes being redeemed to, but excluding, the redemption date.

        Each series of notes will be redeemable, in whole or in part, at our option at any time from time to time on or after the applicable Par Call Date, at a redemption price equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest to, but excluding, the date of redemption.

        If money sufficient to pay the redemption price of all of the notes (or portions thereof) to be redeemed on the redemption date is deposited with the trustee or paying agent on or before the redemption date and certain other conditions are satisfied, then on and after such redemption date, interest will cease to accrue on such series of notes (or such portion thereof) called for redemption.

        "Bund Rate" means, with respect to any redemption date, the rate per annum equal to the equivalent yield to maturity as of such redemption date of the Comparable German Bund Issue, assuming a price for the Comparable German Bund Issue (expressed as a percentage of its principal amount) equal to the Comparable German Bund Price for such redemption date.

        "Comparable German Bund Issue" means the German Bundesanleihe security selected by any Reference German Bund Dealer as having a fixed maturity most nearly equal to the period from such redemption date to the applicable Par Call Date for each series, and that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities in a principal amount approximately equal to the then outstanding principal amount of the notes and of a maturity most nearly equal to the applicable Par Call Date for each series; provided, however, that, if the period from such redemption date to the applicable Par Call Date for each series is less than one year, a fixed maturity of one year shall be used.

        "Comparable German Bund Price" means, with respect to any redemption date, the average of all Reference German Bund Dealer Quotations for such date (which, in any event, must include at least two such quotations), after excluding the highest and lowest such Reference German Bund Dealer Quotations, or if we obtain fewer than four such Reference German Bund Dealer Quotations, the average of all such quotations.

        "Reference German Bund Dealer" means any dealer of German Bundesanleihe securities that we select.

        "Reference German Bund Dealer Quotations" means, with respect to each Reference German Bund Dealer and any redemption date, the average as determined by the Company of the bid and

S-33

Table of Contents

offered prices for the Comparable German Bund Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference German Bund Dealer at 3:30 p.m., Frankfurt, Germany time, on the third Business Day preceding such redemption date.

        If we elect to redeem less than all of any series of the notes, and such notes are at the time represented by a global note, then the particular notes of such series to be redeemed will be selected in compliance with the requirements of the principal securities exchange, if any, on which the notes are listed and in compliance with the requirements of Euroclear Bank S.A./N.V., as operator of the Euroclear System ("Euroclear"), or Clearstream Banking, société anonyme ("Clearstream"), as applicable, or if the notes are not so listed or such exchange prescribes no method of selection and the notes are not held through Euroclear or Clearstream, as applicable, or Euroclear or Clearstream, as applicable, prescribes no method of selection, the paying agent will select the notes to be redeemed by lot. If we elect to redeem less than all of any series of the notes, and any of such notes are not represented by a global note, then the paying agent will select the particular notes of such series to be redeemed in accordance with its customary practices and procedures (and the depositary will select by lot the particular interests in any global note of such series to be redeemed).

        We may at any time, and from time to time, purchase the notes at any price or prices in the open market, through negotiated transactions, by tender offer or otherwise.

        Once notice of redemption is mailed for any series of notes, the notes of such series called for redemption will become due and payable on the redemption date at the applicable redemption price.

        Notice of any redemption of notes in connection with a corporate transaction (including any equity offering, an incurrence of indebtedness or a change of control) may, at the Company's discretion, be given prior to the completion thereof and any such redemption or notice may, at the Company's discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company's obligations with respect to such redemption may be performed by another Person.

Special Mandatory Redemption

        The Company expects to use the net proceeds from this offering as partial consideration for the Acquisition, as described under the heading "Use of Proceeds."

        Each series of the notes will be redeemed in whole at a special mandatory redemption price (the "Special Mandatory Redemption Price") equal to 101% of the aggregate principal amount of the applicable series of notes, plus accrued and unpaid interest on the principal amount of such series of the notes to, but excluding, the Special Mandatory Redemption Date (as defined below), if (i) the closing of the Acquisition has not occurred on or prior to November 11, 2016 (or if, pursuant to Purchase Agreement the Termination Date (as defined therein) is automatically extended, the date (not later than 18 months after November 11, 2015) to which the Termination Date is so extended), or (ii) if, prior to such date, we notify the trustee in writing that we will not pursue the Acquisition. Each of (i) and (ii) is a "Special Mandatory Redemption Event").

        Upon the occurrence of a Special Mandatory Redemption Event, the Company shall promptly (but in no event later than 10 Business Days following such Special Mandatory Redemption Event) notify the trustee in writing (such date of notification, the "Redemption Notice Date"), that the notes are to be redeemed on the 30th day following the Redemption Notice Date (such date, the "Special Mandatory Redemption Date"), in each case in accordance with the applicable provisions of the

S-34

indenture. The trustee, upon receipt of the notice specified above, on the Redemption Notice Date shall notify each Holder in accordance with the applicable provisions of the indenture that all of the outstanding notes shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the Holders of any series of the notes. At or prior to 12:00 p.m. (New York City time) on the Special Mandatory Redemption Date, the Company shall deposit funds sufficient to pay the Special Mandatory Redemption Price for each series of notes on such date. If such deposit is made as provided above, the notes will cease to bear interest on and after the Special Mandatory Redemption Date.

Payment of Additional Amounts

        We will, subject to the exceptions and limitations set forth below, pay such additional amounts as will result in the receipt by a holder of such amounts, after deduction for any present or future tax, assessment or other governmental charge of the United States or a political subdivision or taxing authority of or in the United States (a "Relevant Jurisdiction"), imposed by withholding with respect to the payment, as would have been received had no such withholding or deduction been required; provided, however, that the foregoing obligation to pay additional amounts shall not apply:

(1)

to any tax, assessment or other governmental charge of the United States imposed on a holder of a Note that is a "United States person" (as defined below);



(2)

to any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the holder (or the beneficial owner for whose benefit such holder holds such note), or a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership or corporation, or a person holding a power over an estate or trust administered by a fiduciary holder, being considered as:



(a)

being or having been present or engaged in a trade or business in the Relevant Jurisdiction or having had a permanent establishment in the Relevant Jurisdiction;

(3)

to any holder that is not the sole beneficial owner of the notes, or a portion of the notes, or that is a fiduciary, partnership or limited liability company, but only to the extent that a beneficial owner with respect to the holder, a beneficiary or settlor with respect to the fiduciary, or a partner or member of the partnership or limited liability company would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner, partner, or member received directly its beneficial or distributive share of the payment;



(4)

to any tax, assessment or other governmental charge that is imposed or otherwise withheld solely by reason of a failure of the holder or any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the Relevant Jurisdiction of the holder or beneficial owner of the

notes, if compliance is required by statute, by regulation of the Relevant Jurisdiction or any taxing authority therein or by an applicable income tax treaty to which the Relevant Jurisdiction is a party as a precondition to exemption from such tax, assessment or other governmental charge;

(5)

to any tax, assessment or other governmental charge that is imposed otherwise than by withholding or deduction from the payment;



(6)

to any tax, assessment or other governmental charge that is imposed or withheld solely by reason of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the payment becomes due or is duly provided for, whichever occurs later;



(7)

to any estate, inheritance, gift, sales, excise, transfer, wealth, capital gains or personal property tax or similar tax, assessment or other governmental charge;



(8)

to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any note, if such payment can be made without such withholding by any other paying agent;



(9)

to any tax, assessment or governmental charge that would not have been so imposed or withheld but for the presentation by the holder of a note for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;



(10)

any withholding or deduction pursuant to an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (or any regulations, agreements thereunder or official interpretations thereof) or any intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental agreement);



(11)

to any tax, assessment or governmental charge required to be withheld by any paying agent from any payment of principal of or interest on any note as a result of the presentation of any note for payment by or on behalf of a beneficial owner who would have been able to avoid the withholding or deduction by presenting the relevant global note to another paying agent in a Member State of the EU; or



(12)

in the case of any combination of the above items.

        The notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable to the notes. Except as specifically provided under this heading "—Payment of Additional Amounts," we will not be required to make any payment for any tax, assessment or other governmental charge imposed by any government or a political subdivision or taxing authority of or in any government or political subdivision.

        As used under this heading "—Payment of Additional Amounts" and under the heading "—Redemption for Tax Reasons", the term "United States" means the United States of America (including the states and the District of Columbia) and its territories, possessions and other areas subject to its jurisdiction, "United States person" means any individual who is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States person under any applicable Treasury regulations), or any estate or trust the income of which is subject to United States federal income taxation regardless of its source.

Redemption for Tax Reasons

        If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the Relevant Jurisdiction, or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after the date of this prospectus supplement (or, in the case of a successor to the Company, the date of succession), we become or, based upon a written opinion of independent counsel of recognized standing selected by us, there is a substantial probability that we will become, obligated to pay additional amounts as described herein under the heading "—Payment of Additional Amounts" with respect to the notes, then we may at our option redeem, in whole, but not in part, the notes on not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued but unpaid on those notes to the date fixed for redemption, provided such obligation cannot be avoided by our taking reasonable measures available to us.

Repurchase Upon Change of Control Triggering Event

        If a Change of Control Triggering Event (as defined below) occurs with respect to a particular series of notes, unless we have exercised our right to redeem such series of notes upon the occurrence of specified events involving taxation as described above under "—Redemption for Tax Reasons," or we have unconditionally exercised our right to redeem such notes as described herein, each holder of such notes will have the right to require us to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 in excess thereof) of their notes pursuant to the offer described below (the "Change of Control Offer") on the terms set forth in the indenture. In the Change of Control Offer, we will offer payment in cash equal to 101% of the aggregate principal amount of the applicable series of notes repurchased, plus accrued and unpaid interest, if any, on the notes repurchased to, but excluding, the date of purchase (the "Change of Control Payment").

        Within 30 days following any Change of Control Triggering Event with respect to a particular series of notes, or, at our option, prior to the date of consummation of any Change of Control, but after public announcement of the pending Change of Control, we will mail a notice to holders of such series of notes, with a copy to the trustee and the paying agent, describing the transaction or transactions that constitute the Change of Control and offering to repurchase such notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the "Change of Control Payment Date"), pursuant to the procedures required by the indenture and described in such notice. The repurchase obligation with respect to any notice mailed prior to the consummation of the Change of Control, shall be conditioned on the Change of Control Triggering Event occurring on or prior to the payment date specified in the notice.

        To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control provisions of the indenture by virtue of such conflicts.

        On the Change of Control Payment Date, we will, to the extent lawful:

•

accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer;



•

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered and not validly withdrawn; and



•

deliver or cause to be delivered to the trustee the notes properly accepted together with an officer's certificate stating the aggregate principal amount of notes being repurchased.

S-37

Table of Contents

        The paying agent will promptly mail to each holder of notes properly tendered and not validly withdrawn the purchase price for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any notes surrendered; provided that each new note will be in a principal amount of €100,000 or an integral multiple of €1,000 in excess thereof.

        We will not be required to make an offer to repurchase the notes upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all notes properly tendered and not withdrawn under its offer.

        For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:

        "Below Investment Grade Rating Event" means the notes of the applicable series are rated below an Investment Grade Rating by each of the Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control or (2) public notice of our intention to effect a Change of Control, in each case until the end of the 60-day period following the earlier of (1) the occurrence of a Change of Control or (2) public notice of our intention to effect a Change of Control; provided, however, that if during such 60-day period one or more Rating Agencies has publicly announced that it is considering a possible downgrade of the notes, then such 60-day period shall be extended for such time as the rating of the notes by any such Rating Agency remains under publicly announced consideration for possible downgrade. Notwithstanding the foregoing, a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the trustee in writing at our or its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the Below Investment Grade Rating Event).

        "beneficial owner" will be determined in accordance with Rule 13d-3 under the Securities Exchange Act of 1934 the "Exchange Act"), as in effect on the date of the indenture.

        "beneficially own" and "beneficially owned" have meanings correlative to that of beneficial owner.

        "Change of Control" means the occurrence of any of the following: (1) any "person" or "group" (other than the "permitted parties") is or becomes (by way of merger or consolidation or otherwise) the "beneficial owner," directly or indirectly, of shares of our Voting Stock representing 50% or more of the total voting power of all outstanding classes of our Voting Stock or has the power, directly or indirectly, to elect a majority of the members of our board of directors; (2) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties and assets of us and our Subsidiaries, taken as a whole, to any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) other than to (i) us or one of our Subsidiaries, or (ii) one or more permitted parties; or (3) the holders of our capital stock approve any plan or proposal for the liquidation or dissolution of the Company (whether or not otherwise in compliance with the indenture). Notwithstanding the foregoing, (a) a transaction will not be deemed to involve a Change of Control if (i) the Company becomes a direct or indirect wholly owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company's voting stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than

S-38

Table of Contents

50% of the voting stock of such holding company, and (b) the right to acquire Voting Stock (so long as such person does not have the right to direct the voting of the Voting Stock subject to such right) or any veto power in connection with the acquisition or disposition of Voting Stock will not cause a party to be a "beneficial owner."

        "Change of Control Triggering Event" means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

        "Control" means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a Person, whether through the ability to exercise voting power, by contract or otherwise. "Controlling" and "Controlled" have meanings correlative thereto.

        "Investment Grade Rating" means a rating equal to or higher than Baa3 (or the equivalent) by Moody's and BBB–(or the equivalent) by S&P.

        "Moody's" means Moody's Investors Service, Inc., and its successors.

        "person" or "group" have the meanings given to them for purposes of Sections 13(d) and 14(d) of the Exchange Act as in effect on the issue date of the notes (but excluding any employee benefit plan of such person or its subsidiaries, and any person or entity acting in its capacity as trustee, agent or other fiduciary or administrator of any such plan, and any permitted party shall be excluded when determining the members of such "group"), and the term "group" includes any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act as in effect on the issue date of the notes.

        "permitted party" means (a) (i) the Adolph Coors, Jr. Trust, (ii) any trustee of such Trust acting in its capacity as such, (iii) any Person that is a beneficiary of such trust on the date hereof, (iv) any other trust or similar arrangement for the benefit of such beneficiaries, (v) the successors of any such Persons, (vi) any Persons Controlled by such Persons, (vii) Peter H. Coors and Marilyn E. Coors, their estates, their lineal descendants and any other trust for the benefit of such Persons and (viii) any Person who any of the foregoing have voting control over the Voting Stock of the Company held by such Person; and (b) (i) Pentland Securities (1981) Inc., a Canadian corporation, (ii) Lincolnshire Holdings Inc., (iii) Nooya Investments Inc., (iv) Eric Molson and Stephen Molson, their spouses, their estates, their lineal descendants and any trusts for the benefit of such Persons (including, as to any common stock of the Company held by it for the benefit of such Persons, the trust established under the Voting and Exchange Trust Agreement (as defined in the Combination Agreement dated as of July 21, 2004 between the Company and Molson), (v) the successors of any such Persons, (vi) any Persons Controlled by such Persons, and (vii) any Person who any of the foregoing have voting control over the Voting Stock of the Company held by such Person.

        "Rating Agencies" means (1) each of Moody's and S&P; and (2) if either of Moody's or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of our control, a "nationally recognized statistical rating organization" within the meaning of Section 3(a)(62) of the Exchange Act, selected by us (as certified by a resolution of our board of directors) as a replacement agency for Moody's or S&P, or both, as the case may be.

        "S&P" means Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies, Inc., and its successors.

        The term "all or substantially all" as used in the definition of Change of Control will likely be interpreted under applicable state law and will be dependent upon particular facts and circumstances. There may be a degree of uncertainty in interpreting this phrase. As a result, we cannot assure you how a court would interpret this phrase under applicable law if you elect to exercise your rights following the occurrence of a transaction which you believe constitutes a transfer of "all or substantially all" of our assets.

        In calculating the amount of Voting Stock owned by a person or group the Voting Stock "beneficially owned" by any permitted party shall not be included.

Certain Restrictions

        The following restrictions will apply to the notes:

Restrictions on Secured Debt

        If the Company or any Restricted Subsidiary shall incur, issue, assume or enter into a guarantee of any Debt secured by a mortgage, pledge or lien ("Mortgage," provided, however, that in no event shall an operating lease be deemed to constitute a Mortgage) on any Principal Property of the Company or any Subsidiary, or on any Capital Stock of any Restricted Subsidiary, the Company will, or will cause such Subsidiary or Restricted Subsidiary to, secure the notes equally and ratably with (or, prior to) such secured Debt, for so long as such Debt is so secured, unless the aggregate amount of all such secured Debt (for the avoidance of doubt, to the extent such debt is secured by a Mortgage on any Principal Property), when taken together with all Attributable Debt with respect to sale and leaseback transactions involving Principal Properties of the Company or any Subsidiary (with the exception of such transactions which are excluded as described in the next paragraph and in the second paragraph in "—Restrictions on Sales and Leasebacks" below), would not, at the time of such incurrence or guarantee, exceed 15% of Consolidated Net Tangible Assets, as determined based on the most recent available consolidated balance sheet of the Company.

        The above restriction will not apply to Debt secured by:

        (1)   Mortgages existing on any property prior to the acquisition thereof by the Company or a Restricted Subsidiary or existing on any property of any corporation or other entity that becomes a Subsidiary after the date of the indenture prior to the time such corporation becomes a Subsidiary or securing indebtedness that is used to pay the cost of acquisition of such property or to reimburse the Company or a Restricted Subsidiary for that cost; provided, however, that such Mortgage shall not apply to any other property of the Company or a Restricted Subsidiary other than improvements and accessions to the property to which it originally applies;

        (2)   Mortgages to secure the cost of development or construction of such property, or improvements of such property; provided, however, that such Mortgages shall not apply to any other property of the Company or any Restricted Subsidiary;

        (3)   Mortgages in favor of a governmental entity or in favor of the holders of securities issued by any such entity, pursuant to any contract or statute (including Mortgages to secure debt of the pollution control or industrial revenue bond type) or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of construction of the property subject to such Mortgages;

        (4)   Mortgages securing indebtedness owing to the Company or a Guarantor;

        (5)   Mortgages existing on the first date the notes are originally issued;

        (6)   Mortgages required in connection with governmental programs which provide financial or tax benefits, as long as substantially all of the obligations secured are in lieu of or reduce an obligation that would have been secured by a lien permitted under the indenture;

        (7)   extensions, renewals or replacements of the Mortgages referred to in this paragraph (other than Mortgages described in clauses (2) and (4) above) so long as the principal amount of the secured Debt is not increased (except by an amount not to exceed the fees and expenses, including any premium and defeasance costs incurred with such extension, renewal or replacement) and the extension, renewal or replacement is limited to all or part of the same property secured

(and for the avoidance of doubt could have been secured) by the Mortgage so extended, renewed or replaced; or

        (8)   Mortgages in connection with sale and leaseback transactions described in the second paragraph in "—Restrictions on Sales and Leasebacks" below.

        For the avoidance of doubt, the accrual of interest, accretion or amortization of original issue discount or accreted value, the accretion of dividends, and the payment of interest on Debt in the form of additional Debt will not be deemed to be an incurrence, issuance, assumption or guarantee of Debt.

Restrictions on Sales and Leasebacks

        Neither the Company nor any Restricted Subsidiary may enter into any sale and leaseback transaction involving any Principal Property, unless the aggregate amount of all Attributable Debt with respect to such transactions, when taken together with all secured Debt permitted under the first paragraph in "—Restrictions on Secured Debt" above (and not excluded in the second paragraph thereof) would not, at the time such transaction is entered into, exceed 15% of Consolidated Net Tangible Assets, as determined based on the most recent available consolidated balance sheet of the Company.

        The above restriction will not apply to, and there will be excluded from Attributable Debt in any computation under this restriction, any sale and leaseback transaction if:

        (1)   the transaction is between or among two or more of the Company and the Guarantors;

        (2)   the lease is for a period, including renewal rights, of not in excess of three years;

        (3)   the transaction is with a governmental authority that provides financial or tax benefits;

        (4)   the net proceeds of the sale are at least equal to the fair market value of the property and, within 180 days of the transfer, the Company or the Guarantors repay Funded Debt owed by them or make expenditures for the expansion, construction or acquisition of a Principal Property at least equal to the net proceeds of the sale; or

        (5)   such sale and leaseback transaction is entered into within 180 days after the acquisition or construction, in whole but not in part, of such Principal Property.

SEC Reports

        The indenture will provide that any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act must be filed by us with the trustee (with a copy to the paying agent) within 15 days after the same are required to be filed with the SEC (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Documents filed by us with the SEC via the EDGAR system (or any successor thereto) will be deemed to be filed with the trustee and copied to the paying agent as of the time such documents are filed via EDGAR.

Certain Definitions

        "Attributable Debt" means, as to any particular lease under which any Person is at the time liable and at any date as of which the amount of such liability is to be determined, the total net amount of rent required to be paid by such Person under such lease during the remaining primary term thereof, discounted from the respective due dates thereof to such date at the actual percentage rate inherent in such arrangements as determined in good faith by the Company. The net amount of rent required to be paid under any such lease for any such period shall be the aggregate amount payable by the lessee with respect to such period after excluding amounts required to be paid on account of maintenance and repairs, insurance, taxes, assessments and similar charges. In the case of any lease which is

S-41

Table of Contents

terminable by the lessee upon the payment of a penalty, such net amount shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be terminated.

        "Capital Stock" of any Person means any and all shares, interests, rights to purchase, warrants, options, participations, units or other equivalents of or interests in (however designated) equity of such Person, including any preferred stock, but excluding any debt securities convertible into such equity.

        "Consolidated Net Tangible Assets" means the consolidated total assets of the Company, including its consolidated subsidiaries, after deducting current liabilities (except for those which are Funded Debt or the current maturities of Funded Debt) and goodwill, trade names, trademarks, patents, unamortized debt discount and expense and other intangible assets. Deferred income taxes, deferred investment tax credit or other similar items, as calculated in accordance with GAAP, will not be considered as a liability or as a deduction from or adjustment to total assets.

        "Debt" means with respect to any Person:

        (1)   indebtedness for money borrowed of such Person, whether outstanding on the date of the indenture or thereafter incurred; and

        (2)   indebtedness evidenced by notes, debentures, bonds or other similar instruments for the payment of which such Person is responsible or liable.

        The amount of indebtedness of any Person at any date shall be the outstanding balance at such date of all unconditional obligations as described above and the amount of any contingent obligation at such date that would be classified as indebtedness in accordance with GAAP; provided, however, that (i) in the case of indebtedness sold at a discount, the amount of such indebtedness at any time will be the accreted value thereof at such time and (ii) otherwise the amount of such indebtedness will be the principal amount of such indebtedness.

        "Funded Debt" of any Person means (a) all Debt of such Person having a maturity of more than 12 months from the date as of which the determination is made or having a maturity of 12 months or less but by its terms being renewable or extendable beyond 12 months from such date at the option of such Person, or (b) rental obligations of such Person payable more than 12 months from such date under leases which are capitalized in accordance with GAAP (such rental obligations to be included as Funded Debt at the amount so capitalized).

        "GAAP" means generally accepted accounting principles in the United States which are in effect on the issue date of the notes. At any time after the issue date of the notes, the Company may elect to apply International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS") accounting principles in lieu of GAAP and, upon any such election, references herein to GAAP shall thereafter be construed to mean IFRS on the date of such election; provided that any such election, once made, shall be irrevocable; provided, further, that any calculation or determination in the indenture that requires the application of GAAP for periods that include fiscal quarters ended prior to the Company's election to apply IFRS shall remain as previously calculated or determined in accordance with GAAP.

        "Guarantors" means (a) Molson Coors International LP, Molson Canada 2005, Molson Coors International General, ULC, Molson Coors Callco ULC, Coors International Holdco, ULC, Coors Brewing Company, Molson Coors Holdco Inc., CBC Holdco LLC, MC Holding Company LLC, CBC Holdco 2 LLC and Newco3, Inc., and, no later than 30 days after the consummation of the Acquisition, MillerCoors and (b) each of the Company's future Subsidiaries that guarantees the notes as required by the provisions described under "—Guarantees" above, until in each case, such entity is released as a Guarantor pursuant to the terms of the indenture.

        "Restricted Subsidiary" means a Subsidiary of the Company (a) substantially all the property of which is located, or substantially all the business of which is carried on, within the United States or Canada, and (b) which owns a Principal Property.

        "Significant Subsidiary" means any Subsidiary of the Company that would be a "Significant Subsidiary" within the meaning of Rule 1-02 under Regulation S-X promulgated by the SEC.

        "Voting Stock" of any entity means the class or classes of Capital Stock then outstanding and normally entitled (without regard to the occurrence of any contingency) to vote generally on matters to be decided by the stockholders (or other owners) of such entity (including the election of directors), which, for the avoidance of doubt, in the case of the Company as of the date hereof consists of the Class A common stock and the Special Class A voting stock, taken together.

Merger, Consolidation or Sale of Assets

        The indenture will provide that (i) the Company shall not merge or sell, convey, transfer or lease, in one transaction or a series of transactions, directly or indirectly, all or substantially all of its assets, and (ii) a Guarantor shall not merge or sell, convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets, in each case to any Person unless (i) the successor is organized under the laws of the United States, Canada, Switzerland, the United Kingdom, any member of the European Union or the predecessor's jurisdiction of organization, or any state, province or division thereof, or the District of Columbia, (ii) such successor assumes the obligations of the Company or such Guarantor with respect to the notes or the related guarantee, as applicable, under the indenture (it being understood that any obligation to pay Additional Amounts shall be determined mutatis mutandis, by treating any jurisdiction under the laws of which such successor is organized or resident for tax purposes and any political subdivision or taxing authority as therein having the power to tax, as a Relevant Jurisdiction), and (iii) after giving effect to such transaction, no default or event of default under the indenture will have occurred and be continuing.

Defeasance and Discharge

        The indenture will provide that the Company may elect either (i) to defease and be discharged from any and all obligations with respect to any series of notes (except as otherwise provided in the indenture) ("defeasance") or (ii) to be released, and to have the Guarantors released, from any and all obligations with respect to certain covenants that are described in the indenture ("covenant defeasance"), upon the irrevocable deposit with the paying agent, in trust for such purpose, of money and/or government obligations that through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient, without reinvestment, to pay the principal of, premium, if any, and interest on such series of notes to maturity or redemption, as the case may be (provided that any excess moneys or government obligations and any moneys or government obligations remaining unclaimed after two years from the maturity date or redemption date, as applicable, with

S-43

Table of Contents

respect to such series of notes will be repaid). As a condition to defeasance or covenant defeasance, the Company must deliver to the trustee (with a copy to the paying agent) an opinion of counsel to the effect that the beneficial owners of the notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the indenture. The Company may exercise its defeasance option with respect to any series of notes notwithstanding the prior exercise of the covenant defeasance option with respect thereto. If the Company exercises the defeasance option with respect to any series of notes, payment of such series of the notes may not thereafter be accelerated because of an event of default.

        If the Company exercises the covenant defeasance option with respect to any series of notes, payment of such series of notes may not thereafter be accelerated by reference to any covenant from which the Company and the Guarantors were released as described under clause (ii) of the immediately preceding paragraph. However, if acceleration were to occur for other reasons, the realizable value at the acceleration date of the money and government obligations in the defeasance trust could be less than the principal and interest then due on the applicable series of notes, in that the required deposit in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors.

        As used in this section, "government obligations" means euro-denominated securities that are direct obligations (or certificates representing an ownership interest in such obligations) of a member state of the European Union as of the date of the indenture (including any agency or instrumentality thereof) for the payment of which the full faith and credit of such government is pledged; provided that such member state has a long-term government debt rating of "A1" or higher by Moody's or "A+" or higher by S&P or the equivalent rating category of another internationally recognized rating agency.

Events of Default

        Each of the following constitutes an event of default under the indenture with respect to each series of notes issued under the indenture:

        (1)   default in the payment of any installment of interest on any series of notes issued under the indenture for 30 days after becoming due;

        (2)   default in the payment of principal (or premium, if any) on any series of notes issued under the indenture when due;

        (3)   default in the performance of any other covenant with respect to any series of notes continuing for 90 days after notice as provided below;

        (4)   if payment of any Debt of the Company, the Guarantors or any of the Company's Significant Subsidiaries in a principal amount exceeding $200 million is accelerated as a result of the failure of the Company, any Guarantor or any of the Company's Significant Subsidiaries to perform any covenant or agreement applicable to such Debt which acceleration is not rescinded or annulled within 60 days after written notice thereof; and

        (5)   certain events of bankruptcy, insolvency or reorganization with respect to the Company.

        If an event of default described in clause (1) through (4) above shall occur and be continuing with respect to any series of notes outstanding, then either the trustee or the holders of at least 25% in principal amount of the applicable series may declare the principal and premium, if any, of the notes of such series and the accrued interest thereon, if any, to be due and payable. If an event of default described in clause (5) above shall occur and be continuing, then the principal and premium, if any, of

S-44

Table of Contents

all of the series of notes and the accrued interest thereon, if any, shall be due and payable without any declaration or other act on the part of the trustee or any holders of any series of the notes. The indenture will provide that the trustee shall, within 90 days after the occurrence of a default known to the trustee, give the holders of each affected series of notes notice of all uncured defaults known to it (the term "default" to mean the events specified above without grace periods); provided that, except in the case of default in the payment of principal of or interest on any series of notes, the trustee shall be protected in withholding such notice if it in good faith determines the withholding of such notice is in the interest of the holders of such affected series and so advises the Company in writing. At any time after such declaration of acceleration has been made, the holders of a majority in principal amount of such series of notes, by written notice to the Company and the trustee, may, in certain circumstances, rescind and annul such declaration with respect to such series of notes, provided that such rescission would not conflict with any judgment or decree, and if all existing events of default have been cured or waived except non-payment of the principal amount or premium, if any, or interest on the notes of such series that has become due solely because of acceleration.

        We will furnish to the trustee (with a copy to the paying agent) within 120 days after the end of the Company's fiscal year (and at least once in each 12 month period and at any other reasonable time upon demand of the trustee) a statement by certain officers to the effect that, to the best of their knowledge, no default has occurred under the indenture or, if there has been a default, specifying each such default. The holders of a majority of the outstanding principal amount of any series of notes affected will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series of notes, and to waive certain defaults with respect thereto. The indenture will provide that in case an event of default shall occur and be continuing, the trustee shall exercise such of its rights and powers under the indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of any series of notes unless they first shall have offered to the trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request.

        Before any holder of any series of notes may institute action for any remedy, except payment on such holder's notes when due, the holders of not less than 25% in principal amount of the notes of such series outstanding must request the trustee to take action and certain other conditions must be met. Holders must also offer and give the trustee security or indemnity reasonably satisfactory to it against liabilities incurred by the trustee for taking such action.

        If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euros will be converted into U.S. dollars on the basis of the most recently available market exchange rate for euro. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default.

Modification of the Indenture and Waiver

        The indenture will provide that the Company, the Guarantors (except that with respect to clause (1) below with respect to the addition of guarantors, the signatures of the other Guarantors shall

S-45

not be required) and the trustee may enter into supplemental indentures without the consent of the holders of any series of notes to:

        (7)   prohibit the authentication and delivery of additional series of notes;

        (8)   provide for uncertificated notes in addition to or in place of certificated notes subject to applicable laws;

        (9)   establish the form or terms of other debt securities issued under the indenture and coupons of any series of such other debt securities pursuant to the indenture and to change the procedures for transferring and exchanging such other debt securities so long as such change does not adversely affect the holders of any outstanding debt securities, including the notes (except as required by applicable securities laws);

        (10) make any change to the indenture that does not adversely affect the rights of any holder of any series of debt securities, including the notes;

        (11) secure any series of debt securities, including the notes;

        (12) evidence the acceptance of appointment by a successor trustee and to add to or arrange any provisions of the indenture necessary for or to facilitate the administration of the trusts created under the indenture by more than one trustee;

        (13) comply with the merger and consolidation provisions pursuant to the indenture;

        (14) in the case of subordinated debt securities, to make any change to the provisions of the indenture or any supplemental indenture relating to subordination that would limit or terminate the benefits available to any holder of Senior Debt under such provisions (but only if each such holder of Senior Debt under such provisions consents to such change);

        (15) evidence the release of any Guarantor pursuant to the terms of the indenture;

        (16) add to, change, or eliminate any of the provisions of the indenture with respect to one or more series of debt securities, so long as any such addition, change or elimination not otherwise permitted under the indenture shall: (i) neither apply to any debt security of any series including the notes, created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the holders of any such debt security with respect to the benefit of such provision; or (ii) become effective only when there is no such prior security outstanding; or

        (17) conform the indenture and/or the notes to this "Description of the Notes."

        The indenture will also contain provisions permitting the Company, the Guarantors and the trustee, with the consent of the holders of not less than a majority in aggregate principal amount of

S-46

each series of notes affected to add any provisions to, or change in any manner or eliminate any of the provisions of, the indenture or modify in any manner the rights of the holders of such series of notes so affected. However, the Company may not, without the consent of each holder of notes of each series so affected:

        (1)   extend the final maturity of such series of notes;

        (2)   reduce the principal amount (or premium, if any) of such series of notes;

        (3)   reduce the rate or extend the time of payment of interest on such series of notes;

        (4)   reduce any amount payable on redemption of such series of notes or change the time (other than with respect to timing of notices of redemption) at which such series of notes may be redeemed in accordance with the indenture;

        (5)   impair the right of any holder of such series of notes to institute suit for the payment of such series of notes;

        (6)   reduce the percentage in principal amount of such series of notes the consent of the holders of which is required for any such modification;

        (7)   make such series of notes payable in currency other than that stated in such series of notes;

        (8)   make any changes in the ranking or priority of such series of notes that would adversely affect the holders of such series of notes;

        (9)   make any change to the guarantees made by any Guarantors that would adversely affect the rights of holders of such series of notes; or

        (10) amend the above items or applicable sections of the indenture providing certain rights to the majority of holders of such series of notes.

        The holders of at least a majority in principal amount of each series affected thereby then outstanding, may waive compliance by the Company and the Guarantors with certain restrictive provisions of the indenture applicable to such series. The holders of not less than a majority in principal amount of each series affected thereby then outstanding may waive any past default under the indenture applicable to such series, except a default (a) in the payment of principal of (and premium, if any) or any interest on such series, (b) in respect of a covenant, or provision of the indenture which cannot be modified or amended without the consent of the holder of each note of such series outstanding affected, or (c) arising from the failure to redeem or purchase notes of that series when required pursuant to the terms of the indenture.

Sinking Fund

        There will not be a sinking fund for the notes.

Governing Law

        The indenture and the notes will be governed by and construed in accordance with the laws of the State of New York.

Concerning the Trustee, Paying Agent, Registrar and Transfer Agent

        Deutsche Bank Trust Company Americas will be the trustee, registrar, transfer agent and paying agent under the indenture. The Issuer may change the paying agent, the registrar or the transfer agent without prior notice to the holders, and the Company or any of its Subsidiaries may act as the paying agent, the registrar or the transfer agent.

S-47

---

Table of Contents

        We have customary banking relationships with Deutsche Bank Trust Company Americas and its affiliates. In addition, Deutsche Bank Trust Company Americas may serve as trustee for other debt securities issued by the Company from time to time.

        Except during the continuance of an event of default, the trustee need perform only those duties that are specifically set forth in the indenture and no others, and no implied covenants or obligations will be read into the indenture against the trustee. In case an event of default has occurred and is continuing, the trustee shall exercise those rights and powers vested in it by the indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. No provision of the indenture will require the trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties thereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense.

Listing

        We intend to apply for the notes to be listed and admitted to trading on the New York Stock Exchange. We cannot assure you that such application will be approved. If such a listing is obtained, we have no obligation to maintain such listing and we may delist the notes at any time.

Payments in Euro

        Holders will be required to pay for the notes in euro, and all payments of interest and principal, including payments made upon any redemption of the notes, will be payable in euro. If, on or after the date of this prospectus supplement, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars on the basis of the most recently available market exchange rate for euro. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. Neither the trustee nor the paying agent shall have any responsibility for any calculation or conversion in connection with the forgoing.

Judgment Currency

        The indenture will provide that the Company will agree, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court with respect to the notes it is necessary to convert the sum due in respect of the principal, premium, if any, or interest, if any, payable with respect to such notes into a currency in which a judgment can be rendered (the "Judgment Currency"), the rate of exchange from the currency in which payments under such notes is payable (the "Required Currency") into the Judgment Currency will be the highest bid quotation (assuming European style quotation—i.e., Required Currency per Judgment Currency) received by the Company from three recognized foreign exchange dealers in the City of New York for the purchase of the aggregate amount of the judgment (as denominated in the Judgment Currency) on the Business Day preceding the date on which a final unappealable judgment is rendered, for settlement on such payment date, and at which the applicable dealer timely commits to execute a contract, and (b) the Company's obligations under the indenture to make payments in the Required Currency (i) will not be discharged or satisfied by any tender, or by any recovery pursuant to any judgment (whether or not entered in accordance with the preceding clause (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery will result in the actual receipt by the judgment creditor of the full amount of the Required Currency expressed to be payable

S-48

Table of Contents

in respect of such payments, (ii) will be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt will fall short of the full amount of the Required Currency so expressed to be payable, and (iii) will not be affected by judgment being obtained for any other sum due under the indenture.

Book-Entry, Clearance and Settlement

        The notes will be issued in the form of one or more fully registered global notes (each a "global note") which will be deposited with, or on behalf of, a common depositary (the "Depositary") for the accounts of Euroclear and Clearstream, as applicable, or any successor thereto, and registered in the name of the Depositary's nominee.

        Investors who hold beneficial interests in a global note may hold such interests directly through Euroclear and Clearstream if they are participants in these systems, or indirectly through organizations that are participants in Euroclear or Clearstream. Euroclear and Clearstream will hold interests in the global notes on behalf of their participants through customers' securities accounts in their respective names on the books of their respective depositaries.

        We will not issue notes in certificated form except in certain circumstances. Instead, Euroclear and/or Clearstream will credit on its book-entry registration and transfer systems a participant's account with the interest beneficially owned by such a participant. The laws of some jurisdictions, including certain states of the United States, may require that certain purchasers of securities take physical delivery of such securities in definitive form. The foregoing limitations may impair the ability to own, transfer or pledge book-entry interests. In addition, while the notes are in global form, owners of interests in a global note will not have the notes registered in their names, will not receive physical delivery of the notes in certificated form and will not be considered the registered owners or "holders" of notes under the indenture for any purpose. Beneficial interests in the global notes will be issued in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Book-entry interests will be limited to persons that have accounts with Euroclear and/or Clearstream or persons that may hold interests through such participants. Book-entry interests will be shown on, and transfers thereof will be effected only through, records maintained in book-entry form by Euroclear and/or Clearstream and their participants.

        So long as the notes are held in global form, the Depositary will be considered the holder of the global notes for all purposes under the indenture. As such, participants must rely on the procedures of Euroclear and/or Clearstream and indirect participants must rely on the procedures of Euroclear and/or Clearstream and the participants through which they own book-entry interests in order to exercise any rights of holders under the indenture.

        Neither the Company, nor the trustee under the indenture, nor any of the Company's or the trustee's respective agents will have any responsibility or be liable for any aspect of the records relating to the book-entry interests.

        Euroclear and Clearstream have advised us that Euroclear and Clearstream hold securities for participating organizations. They also facilitate the clearance and settlement of securities transactions between their respective participants through electronic book-entry changes in the accounts of such participants. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance, settlement, lending and borrowing of internationally traded securities. Euroclear and Clearstream interface with domestic securities markets. Euroclear and Clearstream participants are financial institutions such as underwriters, securities brokers and dealers, banks, trust companies and certain other organizations. Indirect access to Euroclear or Clearstream is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Euroclear or Clearstream participant, either directly or indirectly.

Table of Contents

        If Euroclear or Clearstream, as applicable, notifies us that it is unwilling or unable to continue as a clearing system in connection with the global notes or, Euroclear or Clearstream, as applicable, ceases to be a clearing system, and in each case a successor clearing system is not appointed by us after receiving such notice or on becoming aware that Euroclear and Clearstream are no longer so registered, we will issue or cause to be issued individual certificates in registered form on registration of transfer of, or in exchange for, book-entry interests in the notes represented by such global notes upon delivery of such global notes for cancellation.

        Title to book-entry interests in the notes will pass by book-entry registration of the transfer within the records of Clearstream or Euroclear, as the case may be, in accordance with their respective procedures. Book-entry interests in the notes may be transferred within Clearstream and within Euroclear and between Clearstream and Euroclear in accordance with procedures established for these purposes by Clearstream and Euroclear.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

        The following is a general discussion of the material United States federal income tax consequences of the purchase, ownership and disposition of the notes. This discussion only applies to an investor that acquires the notes pursuant to this offering at the price indicated on the cover of this prospectus supplement. This discussion is based upon the United States Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations and judicial decisions and administrative interpretations thereof, all as of the date hereof and all of which are subject to change, possibly with retroactive effect. This discussion is limited to investors that hold the notes as capital assets for United States federal income tax purposes. Furthermore, this discussion is general in nature and does not address all aspects of United States federal income taxation that may be applicable to investors in light of their particular circumstances (including the impact of the Medicare contribution tax on net investment income), or to investors subject to special treatment under United States federal income tax law, such as banks and other financial institutions, insurance companies, regulated investment companies, real estate investment trusts, brokers, retirement plans, individual retirement accounts or other tax-deferred accounts, pension plans, subchapter S corporations, tax-exempt organizations, persons that are in the same "expanded group" or "modified expanded" group (each within the meaning of Proposed Treasury regulation §1.385-1) as the Company, entities that are treated as partnerships for United States federal income tax purposes and their partners, dealers or traders in securities or currencies, expatriates and former long-term residents, United States Holders (as defined below) whose "functional currency" is not the United States dollar and persons that hold the notes as part of a straddle, hedge, conversion transaction or other integrated investment. Furthermore, this discussion does not address any United States federal estate or gift tax consequences or any state, local or foreign tax consequences.

        The following discussion is not a substitute for careful tax planning and advice. Investors considering the purchase of notes should consult their own tax advisors with respect to the application of the United States federal income tax laws to their particular situations, as well as any tax consequences arising under the estate or gift tax laws or the laws of any state, local or non-United States taxing jurisdiction, or under any applicable tax treaty.

        For purposes of this discussion, the term "United States Holder" means a beneficial owner of the notes that is (1) an individual who is a citizen or resident of the United States, (2) a corporation or other entity treated as a corporation for United States federal income tax purposes that is created or organized in or under the laws of the United States or any political subdivision thereof, (3) a trust if it (i) is subject to the primary supervision of a United States court and the control of one or more United States persons or (ii) was in existence on August 20, 1996 and has a valid election in effect under applicable Treasury regulations to be treated as a United States person, or (4) an estate, the income of which is subject to United States federal income tax regardless of its source.

        The term "Non-United States Holder" means a beneficial owner (other than a partnership for United States federal income tax purposes) of notes that is not a United States Holder.

        If a partnership (including any entity or arrangement treated as a partnership for United States federal income tax purposes) owns notes, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. Partners in a partnership that owns the notes should consult their tax advisors as to the particular United States federal income tax consequences applicable to them.

Consequences to United States Holders

Additional Payments

        In certain circumstances (see, for instance, "Description of the Notes—Special Mandatory Redemption," "Description of the Notes—Repurchase Upon Change of Control Triggering Event" and "Description of the Notes—Optional Redemption"), we may be obligated or elect to pay amounts in excess of stated interest or principal on the notes. If any such payment is treated as a contingent payment, subject to certain exceptions, the notes may be treated as contingent payment debt instruments, in which case the timing and amount of income inclusions and the character of income recognized may be different from the consequences discussed herein. Although the issue is not free from doubt, we intend to take the position that the possibility of such additional amounts payable on the notes is a remote or incidental contingency within the meaning of applicable Treasury regulations as of the date hereof, and thus does not result in the notes being treated as contingent payment debt instruments under applicable Treasury regulations. Therefore, we do not intend to treat the potential payment of additional interest or the potential payment of a premium pursuant to the optional redemption, special mandatory redemption or optional repurchase provisions as part of the yield to maturity of the notes. Our determination that this contingency is remote or incidental is binding on a United States Holder, unless such United States Holder explicitly discloses to the Internal Revenue Service (the "IRS") on its tax return for the year during which it acquires the notes that it is taking a different position. However, our position is not binding on the IRS. If the IRS takes a contrary position to that described above, a United States Holder may be required to accrue income on its notes in excess of stated interest, and to treat as ordinary income rather than capital gain any income recognized on the taxable disposition of a note. United States Holders should consult their tax advisor regarding the tax consequences if the notes were treated as contingent payment debt instruments. The discussion below assumes that the notes will not be treated as contingent payment debt instruments.

Payments of interest

        It is anticipated, and this discussion assumes, that the notes will not be issued with original issue discount for U.S. federal income tax purposes. In such case, interest on a note will generally be treated as ordinary income at the time it is paid or accrued in accordance with a United States Holder's usual method of accounting for U.S. federal income tax purposes. If, however, the notes are issued for an amount less than the principal amount and the difference is more than a de minimis amount (as set forth in the Code), a United States Holder will be required to include the difference in income as original issue discount as it accrues in accordance with a constant-yield method based on a compounding of interest, before the receipt of cash payments attributable to this income.

        A United States Holder that uses the cash method of tax accounting will be required to include in income the U.S. dollar value of the euro denominated interest payment on a note based on the spot rate of exchange on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars. No foreign currency exchange gain or loss will be recognized with respect to the receipt of such payment (other than foreign currency exchange gain or loss realized on the disposition of the euros so received, see "—Transaction in Euros," below).

        A United States Holder that uses the accrual method of tax accounting will accrue interest income on a note in euros and translate the amount accrued into U.S. dollars based on:

•

the average exchange rate in effect during the interest accrual period, or portion thereof, within such United States Holder's taxable year; or



•

at such United States Holder's election, at the spot rate of exchange on (1) the last day of the accrual period, or the last day of the taxable year within such accrual period if the accrual period spans more than one taxable year, or (2) the date of receipt, if such date is within five

S-52

---

Table of Contents

business days of the last day of the accrual period. Such election must be applied consistently by the United States Holder to all debt instruments from year to year and can be changed only with the consent of the IRS.

        A United States Holder that uses the accrual method of tax accounting will recognize foreign currency exchange gain or loss on the receipt of an interest payment equal to the difference between (i) the value of the euros received as interest, as translated into U.S. dollars using the spot rate of exchange on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars, and (ii) the U.S. dollar amount previously included in income with respect to such payment. Such foreign currency exchange gain or loss will be treated as ordinary income or loss but generally will not be treated as an adjustment to interest income received on the notes.

Sale, exchange, redemption or other taxable disposition of notes

        Upon the sale, exchange, retirement at maturity, redemption or other taxable disposition of a note, except as noted below with respect to foreign currency exchange gain or loss, a United States Holder generally will recognize capital gain or loss equal to the difference between the amount realized by such United States Holder (except to the extent such amount is attributable to accrued but unpaid interest, which will be taxable as described above under "—Consequences to United States Holders—Payment of interest") and such United States Holder's adjusted tax basis in the note. Subject to the discussion below, the adjusted tax basis of a note to a United States Holder will generally be the U.S. dollar value of the euro purchase price calculated at the spot rate of exchange on the date of purchase and the amount realized by a United States Holder upon the disposition of a note will generally be the U.S. dollar value of the euros received calculated at the spot rate of exchange on the date of disposition.

        If the notes are traded on an established securities market, a United States Holder that uses the cash method of tax accounting, and if it so elects, a United States Holder that uses the accrual method of tax accounting, will determine the U.S. dollar values of its adjusted tax bases in the note and the amount realized on the disposition of a note by translating euro amounts at the spot rate of exchange on the settlement date of the purchase or the disposition, respectively. The election available to accrual basis United States Holders discussed above must be applied consistently by the United States Holder to all debt instruments from year to year and can be changed only with the consent of the IRS. If an accrual method taxpayer does not make this election, it will recognize foreign currency exchange gain or loss (taxable as ordinary gain or loss) upon the sale, exchange, retirement, redemption or other disposition of the notes to the extent that the U.S. dollar value of the euros received (based on the spot rate on the settlement date) differs from the U.S. dollar value of the amount realized.

        Any capital gain or loss will be long-term capital gain or loss if the United States Holder's holding period for the notes exceeds one year on the date of disposition. Long-term capital gains recognized by non-corporate United States Holders are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

        Gain or loss recognized by a United States Holder on a sale, exchange, retirement at maturity, redemption or other taxable disposition of a note generally will be treated as ordinary income or loss to the extent that the gain or loss is attributable to changes in the euro to U.S. dollar exchange rate during the period in which the United States Holder held such note. Such foreign currency exchange gain or loss will equal the difference between the U.S. dollar value of the euro purchase price calculated at the spot rate of exchange on the date (1) the note is disposed of (or the spot rate on the settlement date, if applicable) and (2) of purchase (or the spot rate on the settlement date, if applicable). The recognition of foreign currency exchange gain or loss on a sale, exchange, retirement at maturity or other taxable disposition (with respect to both principal and interest) will be limited to

S-53

---

Table of Contents

the amount of overall gain or loss realized on the disposition of a note. Any gain or loss realized in excess of the foreign currency exchange gain or loss will be capital gain or loss.

Transaction in Euros

        Euros received as interest on, or on a disposition of, a note will have a tax basis equal to their U.S. dollar value at the time such interest is received or at the time such proceeds from disposition are received. The amount of gain or loss recognized on a sale or other disposition of such euros will be equal to the difference between (1) the amount of U.S. dollars, or the fair market value in U.S. dollars of the other property received in such sale or other disposition, and (2) the United States Holder's adjusted tax basis in such euros. As discussed above, if the notes are traded on an established securities market, a cash basis United States Holder (or an electing accrual basis United States Holder) will determine the U.S. dollar value of the euros by translating the euros received at the spot rate of exchange on the settlement date of the purchase or the disposition. A United States Holder that purchases a note with previously owned euros will generally recognize gain or loss in an amount equal to the difference, if any, between such United States Holder's adjusted tax basis in such euros and the U.S. dollar fair market value of such note on the date of purchase.

        Any such gain or loss generally will be ordinary income or loss and will not be treated as interest income or expense. The conversion of U.S. dollars to euros and the immediate use of such euros to purchase a note generally will not result in any exchange gain or loss for a United States Holder.

Reportable Transaction Reporting

        Under applicable Treasury regulations, a United States Holder who participates in "reportable transactions" (as defined in the Treasury regulations) must attach to its United States federal income tax return a disclosure statement on IRS Form 8886. The Treasury regulations could be interpreted to cover transactions generally not regarded as tax shelters, including certain foreign currency transactions. Under the relevant rules, a United States Holder may be required to treat a foreign currency exchange loss from the notes as a reportable transaction if this loss exceeds the relevant threshold in the Treasury regulations. United States Holders should consult their own tax advisors to determine the tax reporting obligations, if any, including any requirement to file IRS Form 8886, with respect to the ownership or disposition of the notes or any related transaction such as the disposition of any euros received in respect of the notes.

Information reporting and backup withholding

        Information reporting requirements generally will apply to payments of interest on the notes and to the proceeds from a sale of notes unless a United States Holder is an exempt recipient. Backup withholding may apply to those payments unless a United States Holder provides its correct taxpayer identification number, or certification of exempt status. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a credit against a United States Holder's federal income tax liability and may entitle such holder to a refund, provided the required information is timely furnished to the IRS.

Consequences to Non-United States Holders

Stated interest

        Subject to the discussions below concerning backup withholding and the FATCA withholding (as defined below), a Non-United States Holder generally will not be subject to United States federal income or withholding tax on payments of interest on the notes provided that the Non-United States Holder (A) does not actually or constructively own 10% or more of the total combined voting power of all classes of our voting stock, (B) is not a controlled foreign corporation related to us directly or

S-54

---

Table of Contents

constructively through stock ownership, (C) is not a bank that acquired the notes in consideration for an extension of credit made pursuant to a loan agreement entered into in the ordinary course of business, and (D) satisfies certain certification requirements. Such certification requirements will generally be met if (x) the Non-United States Holder provides its name and address, and certifies on IRS Form W-8BEN or Form W-8BEN-E (or a substantially similar form), under penalties of perjury, that it is not a United States person or (y) a securities clearing organization or certain other financial institutions holding the note on behalf of the Non-United States Holder certifies on Form W-8IMY, under penalties of perjury, that such certification from the Non-United States Holder has been received by it and furnishes us or our paying agent with a copy thereof, together with any applicable underlying IRS forms sufficient to establish that the Non-United States Holders is not a United States person or (z) the Non-United States Holder holds its note directly through a "qualified intermediary" (within the meaning of applicable Treasury regulations) and certain conditions are satisfied. In addition, we or our paying agent must not have actual knowledge or reason to know that the beneficial owner of the note is a United States person. If a Non-United States Holder cannot satisfy the requirements outlined above, then interest on the notes will generally be subject to United States withholding tax at a 30% rate unless such Non-United States Holder provides us with (A) a properly executed IRS Form W-8BEN or Form W-8BEN-E (or other applicable form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty, or (B) IRS Form W-8ECI (or other applicable form) stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with the conduct of a trade or business in the United States.

        If a Non-United States Holder is engaged in a trade or business in the United States and interest on the notes (or gain from a sale or other taxable disposition) is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base) then, the Non-United States Holder will be exempt from the 30% withholding tax provided the certification requirements discussed above are satisfied. However, such Non-United States Holder will be subject to United States federal income tax on that interest on a net-income basis in the same manner as if such Non-United States Holder were a United States Holder as described above. In addition, if a Non-United States Holder is a foreign corporation, such effectively connected income may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate, or such lower rate as may be specified under an applicable income tax treaty. Non-United States Holders engaged in the conduct of a trade or business in the United States are urged to consult their own tax advisors regarding the U.S. federal income tax consequences of ownership and disposition of the notes.

Disposition of the notes

        Subject to the discussions below concerning backup withholding and the FATCA withholding (as defined below), a Non-United States Holder will not be subject to United States federal income tax with respect to gain recognized on the disposition of the notes unless:

•

the gain is effectively connected with the conduct of a United States trade or business of such holder (and, where an income tax treaty applies, is attributable to a United States permanent establishment or fixed base); or



•

the Non-United States Holder is an individual who is present in the United States for 183 or more days in the taxable year and certain other conditions are satisfied.

        A Non-United States Holder described in the first bullet point above will generally be subject to United States federal income tax on that gain on a net-income basis in the same manner as if such Non-United States Holder were a United States Holder as described above. In addition, if a Non-United States Holder is a foreign corporation, such effectively connected income may, under

S-55

---

Table of Contents

certain circumstances, be subject to an additional branch profits tax at a 30% rate, or such lower rate as may be specified under an applicable income tax treaty.

        If a Non-United States Holder is described in the second bullet point above, any gain realized from the sale, exchange, redemption, retirement or other taxable disposition of the notes will be subject to United States federal income tax at a 30% rate (or lower applicable treaty rate), which may be offset by certain United States source capital losses.

Information reporting and backup withholding

        We must report annually to the IRS and to a Non-United States Holder the amount of interest paid to the Non-United States Holder and the amount of tax, if any, withheld with respect to such interest. Unless the Non-United States Holder complies with certification procedures to establish that the Non-United States Holder is not a United States person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other disposition of a note. The IRS may make this information available, under the provisions of an applicable tax treaty, to the tax authorities in the country in which the Non-United States Holder is a resident.

        In addition, a Non-United States Holder may be subject to backup withholding with respect to interest payments on a note, unless, generally, the Non-United States Holder certifies under penalties of perjury (usually on IRS Form W-8BEN or W-8BEN-E) that the Non-United States Holder is not a United States person or the Non-United States Holder otherwise establishes an exemption.

        Additional rules relating to information reporting requirements and backup withholding with respect to the payment of proceeds from the disposition of a note are as follows:

•

If the proceeds are paid to or through the United States office of a broker, a Non-United States Holder generally will be subject to backup withholding and information reporting unless the Non-United States Holder certifies under penalties of perjury that it is not a United States person (usually on an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption.



•

If the proceeds are paid to or through a non-United States office of a broker that is not a United States person and does not have one of certain specified United States connections, a Non-United States Holder generally will not be subject to backup withholding or information reporting.



•

If the proceeds are paid to or through a non-United States office of a broker that is a United States person or that has one of the specified United States connections, a Non-United States Holder generally will be subject to information reporting (but generally not backup withholding) unless the Non-United States holder certifies under penalties of perjury that it is not a United States person (usually on an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption.

        Any amounts withheld under the backup withholding rules may be allowed as a credit against the Non-United States Holder's United States federal income tax liability and may entitle such holder to a refund, provided the required information is furnished to the IRS.

FATCA Withholding

        Sections 1471 through 1474 of the Code and the Treasury regulations promulgated thereunder ("FATCA") generally impose a withholding tax of 30% on interest income paid on a debt obligation and for sales or other dispositions after December 31, 2018, on the gross proceeds from the sale or other disposition of a debt obligation to (i) a foreign financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such institution enters into an agreement with the United States government to collect and provide to the United States tax authorities substantial

Table of Contents

information regarding United States account holders of such institution (which would include certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with United States owners) or (ii) a foreign entity that is not a financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such entity provides the withholding agent with a certification identifying the substantial United States owners of the entity, which generally includes any United States person who directly or indirectly owns more than 10% of the entity, in each case, unless another exemption applies. Investors are encouraged to consult with their own tax advisors regarding the implications of FATCA on their investment in a note.

UNDERWRITING

        Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below, for whom Merrill Lynch International, Citigroup Global Markets Limited and UBS Limited are acting as representatives (the "Representatives"), has severally agreed to purchase, and we have agreed to sell to that underwriter, the aggregate principal amount of the applicable series of notes set forth opposite the underwriter's name in the following table:

        The underwriting agreement provides that the obligations of the underwriters to purchase the notes in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. The underwriters are obligated to purchase all of the notes if they purchase any of the notes. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of the notes may be terminated.

        The underwriters propose to offer each series of notes directly to the public at the respective public offering prices set forth on the cover page of this prospectus supplement and may offer notes to certain dealers at a price that represents a concession not to exceed        % of the principal amount of the Senior Notes due 20    and        % of the principal amount of the Senior Notes due 20    . The underwriters may allow, and any such dealer may reallow, a concession not to exceed        % of the principal amount of the Senior Notes due 20    and        % of the principal amount of the Senior Notes due 20    . After the initial offering of the notes to the public, the Representatives may change the respective public offering prices of the notes and other selling terms.

        The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the applicable series of notes).

        We estimate that our total expenses for this offering, other than underwriting discounts and commissions, will be approximately $            .

        It is expected that delivery of the notes will be made against payment therefor on or about                        , 2016, which is the fifth business day following the date hereof (such settlement cycle being referred to as "T+5"). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the notes initially will

S-58

---

Table of Contents

settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes on the date of pricing or the next succeeding business day should consult their own advisors.

        We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

        The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their affiliates have, from time to time, performed, and may in the future perform, various financial advisory, investment banking and commercial banking services for our company, for which they received or will receive customary fees and expenses. Affiliates of certain of the underwriters are lenders under our existing credit facilities. In addition, the underwriters or their affiliates have agreed to provide us with financing under our Term Loan Agreement and Bridge Loan Agreement. An affiliate of UBS Limited also acted as a financial advisor to us in connection with the Acquisition.

        In addition, each of the underwriters or their respective affiliates is acting as an underwriter or initial purchaser, as applicable, of the Concurrent Offerings for which they will receive customary fees and reimbursement of out-of-pocket expenses.

        In connection with the issuance of the notes, we have entered into and may enter into additional interest rate swap agreements with financial institutions, which include one or more of the underwriters or their affiliates. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of our company. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

New Issue of Notes

        There is currently no public trading market for any series of the notes. We have not applied and do not intend to apply to list the notes on any securities exchange. The underwriters have advised us that they intend to make a market in each series of the notes. However, they are not obligated to do so and may discontinue any market-making in the notes at any time in their sole discretion. Therefore, we cannot assure you that liquid trading markets for the notes will develop, that you will be able to sell your notes at a particular time or that the price you receive when you sell will be favorable.

Sales Outside the United States

        The notes may be offered and sold in the United States and certain jurisdictions outside the United States in which such offer and sale is permitted.

Price Stabilization and Short Positions

        In connection with the offering, the underwriters may purchase and sell notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

Class A Common Stock and Class B Common Stock

        Dividends.    Subject to the rights of the holders of any series of Preferred Stock, the holders of Class A Common Stock and the holders of Class B Common Stock are entitled to receive, from legally available funds, dividends when and as declared by our Board of Directors, except that so long as any shares of Class B Common Stock are outstanding, no dividend will be declared or paid on the Class A Common Stock or Class B Common Stock unless at the same time a dividend is declared or paid, on the Class B Common Stock or Class A Common Stock, as applicable, in an amount per share (or number per share, in the case of a dividend paid in the form of shares) equal to the amount per share (or number per share, in the case of a dividend paid in the form of shares) of the dividend declared or paid on the Class A Common Stock or Class B Common Stock, as applicable.

Voting Rights

        Class A Holders.    Except in limited circumstances, so long as any shares of Class A Common Stock or Special Class A Voting Stock is outstanding, the right to vote for all purposes is vested exclusively in the holders of Class A Common Stock and Special Class A Voting Stock (as instructed by the holders of the Class A Exchangeable Shares) (collectively, the "Class A Holders") (see "Special Voting Stock" and "Exchangeable Shares" below), voting together as a single class. The holders of Class A Common Stock are entitled to one vote for each share of Class A Common Stock held, without the right to cumulate votes for the election of directors.

        An affirmative vote is required of a majority of the votes entitled to be cast by the holders of the Class A Common Stock and Special Class A Voting Stock, voting together as a single class, prior to the taking of certain actions, including:

•

the issuance of (i) any shares of Class A Common Stock (other than upon the conversion of Class B Common Stock under circumstances provided in our certificate of incorporation or the exchange or redemption of Class A Exchangeable Shares in accordance with the terms of those Class A Exchangeable Shares), or (ii) securities (other than Class B Common Stock) convertible into or exercisable for Class A Common Stock;

•

the issuance of (i) shares of Class B Common Stock (other than upon the conversion of Class A Common Stock under circumstances provided in our certificate of incorporation or the exchange or redemption of our Class B Exchangeable Shares in accordance with the terms of those Class B Exchangeable Shares), or (ii) securities convertible into or exercisable for Class B Common Stock (other than Class A Common Stock) whether in a single transaction or in a series of related transactions, if the number of shares to be issued (including upon conversion or exchange) is, or will be upon issuance, equal to or greater than 20% of the number of shares of Class B Common Stock outstanding before the issuance of such Class B Common Stock (or securities convertible into or exercisable for shares of Class B Common Stock);

        Pentland Securities (1981) Inc. and the Adolph Coors, Jr. Trust, which together control more than 90% of the Class A Common Stock and Class A Exchangeable Shares, have voting trust agreements through which they have combined their voting power over the shares of Class A Common Stock and the Class A Exchangeable Shares that they own. However, in the event that these two stockholders do not agree to vote in favor of a matter submitted to a stockholder vote (other than the election of directors), the voting trustees will be required to vote all of the Class A Common Stock and Class A Exchangeable Shares deposited in the voting trusts against the matter. There is no other mechanism in the voting trust agreements to resolve a potential deadlock between these stockholders.

        Class B Holders.    The holders of the Class B Common Stock and the Special Class B Voting Stock (as instructed by the holders of the Class B Exchangeable Shares) (collectively, the "Class B Holders") may vote with respect to the following: (i) any matter required by the DGCL, (ii) the election of up to three directors, and (iii) as provided in our certificate of incorporation, including on a non-binding advisory basis on the compensation of our named executive officers and as set forth below under "Class A Holders and Class B Holders." In all other cases, the right to vote is vested exclusively with the Class A Holders. The holders of Class B Common Stock are entitled to one vote for each share of Class B Common Stock held with respect to each matter on which holders of the Class B Common Stock are entitled to vote, without the right to cumulate votes for the election of directors.

        Class A Holders and Class B Holders.    Under our certificate of incorporation, the Class A Holders and the Class B Holders have the right to vote, as separate classes and not jointly, on:

any merger that requires stockholder approval under the DGCL;



•

any sale of all or substantially all of our assets, other than to a related party;

any proposal to dissolve our company or any proposal to revoke the dissolution of our company; or

Conversion Rights

        Conversion from Class A Common Stock to Class B Common Stock.    Our certificate of incorporation provides for the right of holders of Class A Common Stock to convert their stock into Class B Common Stock on a one-for-one basis at any time.

        "Coattail" Conversion Rights.    Our certificate of incorporation also includes a "coattail" provision to provide protection to holders of our Class B Common Stock and the Class B Exchangeable Shares in the case of a proposed tender offer or takeover bid for our Class A Common Stock. A holder of our Class B Common Stock is entitled to receive a notice from us that the conversion right of holders of shares of our Class B Common Stock has come into effect. This notice must include a description of the conversion procedures including the election procedures described below, a copy of the exclusionary offer and any other materials received by us in respect of the offer.

        Subject to conditions described below, if an "exclusionary offer" is made for shares of our Class A Common Stock, each outstanding share of our Class B Common Stock will be convertible into one share of our Class A Common Stock at the option of the holder during the period of time commencing on the eighth day after the date on which an exclusionary offer is made and ending on the last date upon which holders of shares of our Class A Common Stock may accept the exclusionary offer.

        An "exclusionary offer" is an offer to purchase shares of our Class A Common Stock that both: (A) either (1) must, by reason of applicable securities laws or the requirements of a stock exchange on which shares of our Class A Common Stock are listed, be open to all or substantially all holders of our Class A Common Stock, or (2) would, if the offer were made in Canada or a province of Canada, be required to be made to all or substantially all holders of shares of our Class A Common Stock resident in Canada or a province of Canada by reason of applicable securities laws of Canada or a province of Canada, the requirements of a stock exchange on which shares of our Class A Common Stock are listed, or the requirements of the Canada Business Corporations Act; and (B) is not made concurrently with an offer to purchase shares of our Class B Common Stock that is identical to the offer to purchase shares of our Class A Common Stock in terms of price per share and percentage of outstanding shares to be purchased (exclusive of shares owned immediately prior to the offer by the offeror) and in all other respects (except with respect to the conditions that may be attached to the offer to purchase shares of our Class A Common Stock), and having no conditions other than the right

Table of Contents

not to purchase and pay for shares of our Class B Common Stock tendered if no shares of our Class A Common Stock are purchased in the offer for shares of our Class A Common Stock.

        The Class B conversion right will not come into effect if one or more holders owning, in the aggregate, as of the offer date, over 50% of the outstanding shares of our Class A Common Stock and Class A Exchangeable Shares, in each case excluding shares owned by the offeror, provide us with adequate assurances that they are not making or acting with another to make the exclusionary offer and will not participate in the exclusionary offer.

        Any of the holders of our Class B Common Stock can exercise this right by providing a signed written notice to the transfer agent and complying with certain other specified conditions. The holders of our Class B Common Stock must pay any governmental or other tax imposed on or in respect of the conversion into shares of our Class A Common Stock.

        Other.    Holders of Company Common Stock do not have pre-emptive rights to acquire any of our securities. The outstanding shares of Company Common Stock are fully paid and non-assessable. There are no redemption or sinking fund provisions applicable to the Company Common Stock.

Exchangeable Shares

        The Class A Exchangeable Shares and Class B Exchangeable Shares (collectively, "Exchangeable Shares") were issued by Molson Coors Canada Inc. ("MCCI"), a wholly-owned, indirect subsidiary of Molson Coors. The Exchangeable Shares are substantially the economic equivalent of the corresponding shares of Company Common Stock in which they may be exchanged. As of December 31, 2015, there were outstanding 2,888,692 Class A Exchangeable Shares and 16,011,153 Class B Exchangeable Shares

        Dividends.    Holders of Exchangeable Shares are entitled to receive, subject to applicable law, dividends as follows:

•

in the case of a cash dividend declared on a corresponding share of Company Common Stock, an amount in cash for each exchangeable share corresponding to the cash dividend declared on each corresponding share of Company Common Stock in U.S. dollars or in an equivalent amount in Canadian dollars;



•

in the case of a stock dividend declared on a corresponding share of Company Common Stock to be paid in shares of Company Common Stock, in the number of Exchangeable Shares of the relevant class for each Exchangeable Share that is equal to the number of shares of corresponding Company Common Stock to be paid on each corresponding share of Company Common Stock; or



•

in the case of a dividend declared on a corresponding share of Company Common Stock in any other type of property, in the type and amount of property as is economically equivalent as determined by MCCI's board of directors to the type and amount of property to be paid on each corresponding share of Company Common Stock.

        The declaration dates, record dates and payment dates for dividends on the Exchangeable Shares are the same as the relevant dates for the dividends on the shares of corresponding Company Common Stock.

        Voting Rights.    Holders of Exchangeable Shares receive, through a voting trust, the benefit of voting rights, entitling the holder to one vote on the same basis and in the same circumstances as one corresponding share of Company Common Stock. See "Special Voting Stock—Voting Rights" below.

        Other.    The Exchangeable Shares are exchangeable at any time, at the option of the holder on a one-for-one basis for corresponding shares of Company Common Stock. Holders of Class A

Table of Contents

Exchangeable Shares are entitled to convert their stock into Class B Exchangeable Shares on a one-for-one basis at any time.

Special Voting Stock

        We have outstanding one share of Special Class A Voting Stock and one share of Special Class B Voting Stock, through which the holders of Class A Exchangeable Shares and Class B Exchangeable Shares, respectively, may exercise their voting rights with respect to our Company Common Stock in which the corresponding Exchangeable Shares may be exchanged.

        Dividends and Liquidation Rights.    The trustee who holds the Special Class A Voting Stock and the trustee who holds the Special Class B Voting Stock are not entitled to receive any dividends or other distributions or to receive or participate in any distribution of assets upon our voluntary or involuntary liquidation, dissolution or winding up.

        Voting Rights.    The Special Class A Voting Stock and the Special Class B Voting Stock provide the mechanism for holders of the corresponding Exchangeable Shares to provide instructions to vote with the holders of our corresponding Company Common Stock. The trustee who holds the Special Class A Voting Stock and the trustee who holds the Special Class B Voting Stock are each entitled to one vote for each corresponding outstanding Exchangeable Share, excluding shares held by Molson Coors or its subsidiaries, and generally vote together with the corresponding Company Common Stock on all matters on which the holders of the corresponding Company Common Stock are entitled to vote.

        The Special Class A Voting Stock and Special Class B Voting Stock are subject to voting trust arrangements. The trustee which holds the Special Class A Voting Stock and the trustee which holds the Special Class B Voting Stock are required to cast a number of votes equal to the number of then-outstanding corresponding Exchangeable Shares, but will only cast a number of votes equal to the number of corresponding Exchangeable Shares as to which it has received voting instructions from the owners of record of those Exchangeable Shares, other than Molson Coors or its subsidiaries, on the record date of the action, and will cast the votes in accordance with such instructions so received.

        Other.    The trustee who holds the Special Class A Voting Stock and the trustee who holds the Special Class B Voting Stock do not have pre-emptive rights to acquire any of our securities. The outstanding shares of Special Class A Voting Stock and Special Class B Voting Stock are fully paid and non-assessable.

Preferred Stock

        Our certificate of incorporation authorizes our Board of Directors to issue up to 25,000,000 shares of Preferred Stock from time to time in one or more series, generally without any vote or action by the holders of our Company Common Stock, except that the issuance of any shares of Preferred Stock having any voting rights other than those expressly required by the DGCL will be subject to approval by a majority of the voting power of the holders of our Class A Common Stock and Special Class A Voting Stock, voting together as a single class. Subject to this right, our Board of Directors will be authorized to determine the number of shares and designation of any series of Preferred Stock and the dividend rate, dividend rights, liquidation preferences, conversion rights and terms, voting rights, redemption rights and terms and sinking fund terms of any series of Preferred Stock. Depending on the terms of any issued Preferred Stock, any or all series of issued Preferred Stock could have a preference over our Company Common Stock with respect to dividends and other distributions and upon liquidation or dissolution of Molson Coors. Subject to certain conditions as specified in our certificate of incorporation, our Board of Directors, without stockholder approval, can issue Preferred Stock with voting, conversion or other rights that could adversely affect the voting power and other rights of the

holders of Company Common Stock. The issuance of Preferred Stock may decrease the market price of our Company Common Stock.

Anti-Takeover Effects of Certain Provisions of Our Certificate of Incorporation, Bylaws and Delaware Law

        Provisions of our certificate of incorporation, our bylaws and Delaware law could have the effect of delaying or preventing a third party from acquiring us, even if the acquisition would benefit our stockholders. These provisions may delay, defer or prevent a tender offer or takeover attempt of our company that a stockholder might consider in the stockholder's best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our Board of Directors and in the policies formulated by our Board of Directors and to reduce our vulnerability to an unsolicited proposal for a takeover that does not contemplate the acquisition of all of our outstanding shares, or an unsolicited proposal for our restructuring or sale of all or part of our business.

Authorized but Unissued Shares of Common Stock and Preferred Stock

        Subject to certain conditions, our authorized but unissued shares of Company Common Stock and preferred stock are available for our Board of Directors to issue without stockholder approval. As noted above, our Board of Directors, without stockholder approval, has the authority under our certificate of incorporation to issue preferred stock with rights superior to the rights of the holders of Company Common Stock, subject to certain conditions. As a result, preferred stock could be issued quickly, could adversely affect the rights of holders of Company Common Stock and could be issued with terms calculated to delay or prevent a change of control or make removal of management more difficult. We may use the additional authorized shares of Company Common Stock or preferred stock for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of our authorized but unissued shares of Company Common Stock and preferred stock could render more difficult or discourage an attempt to obtain control of our company by means of a proxy contest, tender offer, merger or other transaction.

Election, Nomination and Removal of Directors

        Our Board of Directors has currently set the size of the board at 15 members. Twelve of the 15 directors may be elected by the Class A Holders, and three of the 15 directors may be elected by the Class B Holders. The Class A-C Nominating Subcommittee (consisting of two Coors family directors) may nominate five persons to stand for election to our Board of Directors by the Class A Holders, and the Class A-M Nominating Subcommittee (consisting of two Molson family directors) similarly may nominate five nominees to stand for election to our Board of Directors by the Class A Holders. The Nominating Committee (comprised of an independent director, the members of the Class A-C Nominating Subcommittee and the members of the Class A-M Nominating Subcommittee) may nominate two additional directors to stand for election to our Board of Directors by the Class A Holders. The full Board of Directors may nominate three directors to stand for election to our Board of Directors by the Class B Holders. Any director may be removed, with cause, by a majority vote of the Class A Holders and the Class B Holders, voting together as a single class. Any director may be removed, without cause, by a vote of the holders of a majority of the voting power of the class or classes that elected the director. Further, only our Board of Directors may change the size of our board, subject to certain conditions. Because this system of electing, appointing and removing directors generally makes it more difficult for stockholders to replace a majority of our Board of Directors, it

may discourage a third party from initiating a tender offer or otherwise attempting to gain control of our company, and may maintain the incumbency of our Board of Directors.

Stockholder Advance Notice Procedure

        Our bylaws establish an advance notice procedure for stockholders to make nominations of candidates for election as directors or to bring other business before an annual meeting of the stockholders. Only persons who are nominated by our Board of Directors, or a duly authorized board committee, or by a stockholder who has given timely written notice to the secretary of our company before the meeting at which directors are to be elected, will be eligible for election as directors. This notice is required to include specified information about the stockholder and each proposed director nominee and information regarding each proposed nominee that would be required to be included in a proxy statement filed under the SEC's Rules and Regulations. The stockholder notice procedure provides that the only business that may be conducted at an annual meeting is business that has been brought before the meeting by, or at the direction of, our Board of Directors or by a stockholder who has given timely written notice to our secretary. This notice is required to include a brief description of the business desired to be brought before the meeting and specified information about the stockholder and the stockholder's ownership of our capital stock. These provisions may preclude stockholders from bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders.

Amendment to our Certificate of Incorporation and Bylaws

        Our certificate of incorporation may generally be amended by a majority of our Class A Holders and Class B Holders, voting as a single class, subject to certain exceptions as set forth in our certificate of incorporation which require the vote of a majority of our Class A Holders and Class B Holders, each voting as a separate class and not jointly. Our bylaws may generally be amended by our board of directors, subject to certain exceptions, or by a majority of our Class A Holders.

Delaware Anti-Takeover Statute

        Our certificate of incorporation expressly provides that we will not be governed by Section 203 of the DGCL.

Transfer Agent and Registrar

        The transfer agent and registrar for our Class A Common Stock and Class B Common Stock is Computershare Trust Company, N.A. The transfer agent and registrar for our Class A Exchangeable Shares and Class B Exchangeable Shares is CST Trust Company.

Listing

        Our Class A Common Stock and Class B Common Stock are listed on the New York Stock Exchange under the symbols "TAP A" and "TAP," respectively. Our Class A Exchangeable Shares and Class B Exchangeable Shares are listed on the Toronto Stock Exchange under the symbols "TPX.A" and "TPX.B," respectively.

DESCRIPTION OF THE DEPOSITARY SHARES

General

        We may, at our option, elect to offer fractional shares of preferred stock, which we call depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the applicable prospectus supplement, of a share of a particular series of preferred stock. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights.

        The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

        The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

        The summary of terms of the depositary shares contained in this prospectus is not complete and is subject to, and is qualified in its entirety by, all provisions of the applicable deposit agreement, our certificate of incorporation and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends and Other Distributions

        The depositary will distribute all cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock.

        If there is a distribution other than in cash, the depositary will distribute property (including securities) received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

Liquidation Preference

        If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of the voluntary or involuntary liquidation, dissolution or winding up of us, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Withdrawal of Stock

        Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the

11

---

Table of Contents

number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the deposit agreement or receive depositary receipts evidencing depositary shares therefor.

Redemption of Depositary Shares

        Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

        After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

Voting the Preferred Stock

        Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder's depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of Depositary

        We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and such other charges (including those in connection with the receipt and distribution of dividends, the sale or exercise of rights, the withdrawal of the preferred stock and the transferring, splitting or grouping of depositary receipts) as are expressly provided in the deposit agreement to be for their accounts. If these charges have not been paid by the holders of depositary receipts, the depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt.

Table of Contents

Amendment and Termination of the Deposit Agreement

        The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by the holders of a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

•

all outstanding depositary shares have been redeemed; or



•

there has been a final distribution of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.

Resignation and Removal of Depositary

        The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having the requisite combined capital and surplus as set forth in the applicable agreement.

Notices

        The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, that are delivered to the depositary and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

Limitation of Liability

        Neither we nor the depositary will be liable if either we or it is prevented or delayed by law or any circumstance beyond its control in performing its obligations. Our obligations and those of the depositary will be limited to performance in good faith of our and their duties thereunder. We and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent to give such information and on documents believed to be genuine and to have been signed or presented by the proper party or parties.

        We may, from time to time, issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination.

Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date or other specific circumstances occur.

PLAN OF DISTRIBUTION

        We may sell the securities being offered hereby:

•

directly to purchasers;



•

through agents;



•

through dealers;



•

through underwriters;



•

through a combination of any of the above methods of sale; or



•

through any other methods described in a prospectus supplement.

        We will identify the specific plan of distribution, including any direct purchasers, agents, dealers, underwriters and, if applicable, their compensation, the purchase price, the net proceeds to us, the public offering price, and any discounts or concessions allowed or reallowed or paid to dealers, in a prospectus supplement.

        The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on the New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities.

        Offers to purchase the securities may be solicited directly by us or by agents designated by us from time to time. We will, in the prospectus supplement relating to an offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

        If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we will sell the securities to the dealer, as principal. The dealer, which may be deemed to be an underwriter as that term is defined in the Securities Act, may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. Dealer trading may take place in certain of the securities, including securities not listed on any securities exchange.

        If an underwriter or underwriters are utilized in the sale, we will execute an underwriting agreement with the underwriters at the time of sale to them and the names of the underwriters will be set forth in the applicable prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public. The obligations of underwriters to purchase securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all of the securities of a series if any are purchased.

        We may directly solicit offers to purchase the securities and we may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

        Underwriters, dealers, agents and other persons may be entitled, under agreements that may be entered into with us, to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that they may be required to make in

18

respect thereof. Underwriters, dealers and agents may engage in transactions with, or perform services for, us in the ordinary course of business.

        Any person participating in the distribution of Class B Common Stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of our Class B Common Stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our Class B Common Stock to engage in market-making activities with respect to our Class B Common Stock. These restrictions may affect the marketability of our Class B Common Stock and the ability of any person or entity to engage in market-making activities with respect to our Class B Common Stock.

        In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.
