Preliminary Terms No. 127

Registration Statement No. 333-177923

Dated April 16, 2014

If the final stock price is greater than the initial stock price, for each $10 stated principal amount Trigger PLUS:

$10 + leveraged upside payment

In no event will the payment at maturity exceed the maximum payment at maturity.

If the final stock price is less than or equal to the initial stock price but is greater than or equal to the trigger level, for each $10 stated principal amount Trigger PLUS:

$10 + ($10 × absolute stock return)

In this scenario, you will receive a 1% positive return on the Trigger PLUS for each 1% negative return on the underlying stock. In no event will this amount exceed the stated principal amount plus $2.00.

If the final stock price is less than the trigger level, for each $10 stated principal amount Trigger PLUS:

$10 × stock performance factor

This amount will be less than the stated principal amount of $10 per Trigger PLUS and will represent a loss of at least 20%, and possibly all, of your investment.

Commissions and issue price:

Per Trigger PLUS

Total

As an alternative to direct exposure to the underlying stock that enhances returns for a certain range of positive performance of the underlying stock.

To obtain an unleveraged positive return for a limited range of negative performance of the underlying stock.

To enhance returns and potentially outperform the underlying stock in a moderately bullish scenario.

To potentially achieve similar levels of upside exposure to the underlying stock as a direct investment, subject to the maximum payment at maturity, while using fewer dollars by taking advantage of the leverage factor.

To provide an unleveraged positive return in the event of a decline of the underlying stock but only if the final stock price is greater than the trigger level.

Upside Scenario if the Underlying Stock Appreciates

Absolute Return Scenario

Downside Scenario

Upside Scenario. If the final stock price is greater than the initial stock price, for each $10 principal amount Trigger PLUS investors will receive the $10 stated principal amount plus 125% of the appreciation of the underlying stock over the term of the Trigger PLUS, subject to the maximum payment at maturity. Under the hypothetical terms of the Trigger PLUS, an investor will realize the hypothetical maximum payment at maturity at a final stock price of 124.00% of the initial stock price.

For example, if the underlying stock appreciates 5%, investors will receive a 6.25% return, or $6.25 per Trigger PLUS.

Absolute Return Scenario. If the final stock price is less than or equal to the initial stock price but is greater than or equal to the trigger level, investors will receive a 1% positive return on the Trigger PLUS for each 1% negative return of the underlying stock.

Downside Scenario. If the final stock price is less than the trigger level, investors will receive an amount that is significantly less than the stated principal amount by an amount proportionate to the percentage decrease of the final stock price from the initial stock price. This amount will be less than 80% of the stated principal amount per Trigger PLUS. There is no minimum payment at maturity on the Trigger PLUS.

The Trigger PLUS do not pay interest or guarantee return of any principal and your investment in the Trigger PLUS may result in a loss. The terms of the Trigger PLUS differ from those of ordinary debt securities in that the Trigger PLUS do not pay interest or guarantee the payment of any principal amount at maturity. If the final stock price is less than the trigger level (which is 80% of the initial stock price), the absolute return feature will no longer be available and the payment at maturity will be an amount in cash that is at least 20% less than the stated principal amount of each Trigger PLUS, and this decrease will be by an amount proportionate to the decrease in the value of the underlying stock and may be zero. There is no minimum payment at maturity on the Trigger PLUS, and, accordingly, you could lose your entire initial investment in the Trigger PLUS.

The appreciation potential of the Trigger PLUS is limited by the maximum payment at maturity. The appreciation potential of Trigger PLUS is limited by the maximum payment at maturity of at least $13.00 (at least 130.00% of the stated principal amount) per Trigger PLUS. The actual maximum payment at maturity will be provided in the pricing supplement. Although the leverage factor provides 125% exposure to any increase in the final stock price as compared to the initial stock price on the valuation date, because the maximum payment at maturity will be limited to at least 130.00% of the stated principal amount for the Trigger PLUS, any increase in the final stock price by more than 24.00% (in the case where the maximum payment at maturity is 130.00% of the stated principal amount) will not further increase the return on the Trigger PLUS.

Your maximum downside gain on the Trigger PLUS is limited by the trigger level. — If the final stock price is less than or equal to the initial stock price and greater than or equal to the trigger level, you will receive at maturity $10 plus a return equal to the absolute stock return, which will reflect a 1% positive return for each 1% negative return on the underlying stock, subject to an effective limit of 20%. Because you will not receive a positive return if the underlying stock has depreciated below the trigger level, your maximum downside payment will be $12.00 per $10.00 stated principal amount Trigger PLUS.

The Trigger PLUS are subject to the credit risk of JPMorgan Chase & Co., and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the Trigger PLUS. Investors are dependent on JPMorgan Chase & Co.’s ability to pay all amounts due on the Trigger PLUS. Any actual or anticipated decline in our credit ratings or increase in the credit spreads determined by the market for taking our credit risk is likely to adversely affect the market value of the Trigger PLUS. If we were to default on our payment obligations, you may not receive any amounts owed to you under the Trigger PLUS and you could lose your entire investment.

Economic interests of the issuer, the calculation agent, the agent of the offering of the Trigger PLUS and other affiliates of the issuer may be different from those of investors. We and our affiliates play a variety of roles in connection with the issuance of the Trigger PLUS, including acting as calculation agent and as an agent of the offering of the Trigger PLUS, hedging our obligations under the Trigger PLUS and making the assumptions used to determine the pricing of the Trigger PLUS and the estimated value of the Trigger PLUS, which we refer to as JPMS’s estimated value. In performing these duties, our economic interests and the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Trigger PLUS. The calculation agent will determine the initial stock price and the final stock price and will calculate the amount of payment you will receive at maturity, if any. Determinations made by the calculation agent, including with respect to the occurrence or non-occurrence of market disruption events, and any anti-dilution adjustments, may affect the payment to you at maturity. Moreover, our business activities, including hedging and trading activities, could cause our economic interests to be adverse to yours and could adversely affect any payment on the Trigger PLUS and the value of the Trigger PLUS. It is possible that hedging or trading activities of ours or our affiliates in connection with the Trigger PLUS could result in substantial returns for us or our affiliates while the value of the Trigger PLUS declines. Please refer to “Risk Factors — Risks Relating to the Trigger PLUS Generally” in the accompanying product supplement no. MS-1-III for additional information about these risks.

JPMS’s estimated value of the Trigger PLUS will be lower than the original issue price (price to public) of the Trigger PLUS. JPMS’s estimated value is only an estimate using several factors. The original issue price of the Trigger PLUS will exceed JPMS’s estimated value because costs associated with selling, structuring and hedging the Trigger PLUS are included in the original issue price of the Trigger PLUS. These costs include the selling commissions, the projected profits, if any, that our affiliates expect

to realize for assuming risks inherent in hedging our obligations under the Trigger PLUS and the estimated cost of hedging our obligations under the Trigger PLUS. See “Additional Information about the Trigger PLUS — JPMS’s estimated value of the Trigger PLUS” in this document.

JPMS’s estimated value does not represent future values of the Trigger PLUS and may differ from others’ estimates. JPMS’s estimated value of the Trigger PLUS is determined by reference to JPMS’s internal pricing models. This estimated value is based on market conditions and other relevant factors existing at the time of pricing and JPMS’s assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for Trigger PLUS that are greater than or less than JPMS’s estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the Trigger PLUS could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy Trigger PLUS from you in secondary market transactions. See “Additional Information about the Trigger PLUS — JPMS’s estimated value of the Trigger PLUS” in this document.

JPMS’s estimated value is not determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the Trigger PLUS as well as the higher issuance, operational and ongoing liability management costs of the Trigger PLUS in comparison to those costs for our conventional fixed-rate debt. If JPMS were to use the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the Trigger PLUS to be more favorable to you. In addition, JPMS’s estimated value might be lower if it were based on the interest rate implied by our conventional fixed-rate credit spreads. Consequently, our use of an internal funding rate would have an adverse effect on the terms of the Trigger PLUS and any secondary market prices of the Trigger PLUS. See “Additional Information about the Trigger PLUS — JPMS’s estimated value of the Trigger PLUS” in this document.

The value of the Trigger PLUS as published by JPMS (and which may be reflected on customer account statements) may be higher than JPMS’s then-current estimated value of the Trigger PLUS for a limited time period. We generally expect that some of the costs included in the original issue price of the Trigger PLUS will be partially paid back to you in connection with any repurchases of your Trigger PLUS by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include selling commissions, projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our secondary market credit spreads for structured debt issuances. See “Additional Information about the Trigger PLUS — Secondary market prices of the Trigger PLUS” in this document for additional information relating to this initial period. Accordingly, the estimated value of your Trigger PLUS during this initial period may be lower than the value of the Trigger PLUS as published by JPMS (and which may be shown on your customer account statements).

Secondary market prices of the Trigger PLUS will likely be lower than the original issue price of the Trigger PLUS. Any secondary market prices of the Trigger PLUS will likely be lower than the original issue price of the Trigger PLUS because, among other things, secondary market prices take into account our secondary market credit spreads for structured debt issuances and, also, because secondary market prices (a) exclude selling commissions and (b) may exclude projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the Trigger PLUS. As a result, the price, if any, at which JPMS will be willing to buy Trigger PLUS from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the maturity date could result in a substantial loss to you. See the immediately following risk factor for information about additional factors that will impact any secondary market prices of the Trigger PLUS.

Secondary market prices of the Trigger PLUS will be impacted by many economic and market factors. The secondary market price of the Trigger PLUS during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, projected hedging profits, if any, estimated hedging costs and the closing price of one share of the underlying stock, including:

any actual or potential change in our creditworthiness or credit spreads;

customary bid-ask spreads for similarly sized trades;

secondary market credit spreads for structured debt issuances;

the actual and expected volatility in the prices of the underlying stock;

the time to maturity of the Trigger PLUS;

the dividend rate on the underlying stock;

interest and yield rates in the market generally;

the occurrence of certain events affecting the issuer of the underlying stock that may or may not require an adjustment to the stock adjustment factor, including a merger or acquisition; and

a variety of other economic, financial, political, regulatory and judicial events.

The amount payable on the Trigger PLUS is not linked to the value of the underlying stock at any time other than the valuation date. The final stock price will be based on the closing price of one share of the underlying stock on the valuation date, subject to adjustment for non-trading days and certain market disruption events. Even if the price of one share of the underlying stock appreciates prior to the valuation date but then drops to or below the trigger level by the valuation date, the payment at maturity will be less, and may be significantly less, than it would have been had the payment at maturity been linked to the price of one share of the underlying stock prior to such drop. Although the actual price of one share of the underlying stock on the stated maturity date or at other times during the term of the Trigger PLUS may be higher than the final stock price, the payment at maturity will be based solely on the closing price of one share of the underlying stock on the valuation date.

Investing in the Trigger PLUS is not equivalent to investing in the shares of Apple Inc. Investors in the Trigger PLUS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying stock.

No affiliation with Apple Inc. Apple Inc. is not an affiliate of ours, is not involved with this offering in any way, and has no obligation to consider your interests in taking any corporate actions that might affect the value of the Trigger PLUS. We have not made any due diligence inquiry with respect to Apple Inc. in connection with this offering.

We may engage in business with or involving Apple Inc. without regard to your interests. We or our affiliates may presently or from time to time engage in business with Apple Inc. without regard to your interests and thus may acquire non-public information about Apple Inc. Neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, we or our affiliates from time to time have published and in the future may publish research reports with respect to Apple Inc., which may or may not recommend that investors buy or hold the underlying stock.

The anti-dilution protection for the underlying stock is limited and may be discretionary. The calculation agent will make adjustments to the stock adjustment factor and other adjustments for certain corporate events affecting the underlying stock. However, the calculation agent will not make an adjustment in response to all events that could affect the underlying stock. If an event occurs that does not require the calculation agent to make an adjustment, the value of the Trigger PLUS may be materially and adversely affected. You should also be aware that the calculation agent may make adjustments in response to events that are not described in the accompanying product supplement to account for any diluting or concentrative effect, but the calculation agent is under no obligation to do so or to consider your interests as a holder of the Trigger PLUS in making these determinations.

Hedging and trading activities by the calculation agent and its affiliates could potentially affect the value of the Trigger PLUS. The hedging or trading activities of the issuer’s affiliates and of any other hedging counterparty with respect to the Trigger PLUS on or prior to the pricing date and prior to maturity could adversely affect the value of the underlying stock and, as a result, could decrease the amount an investor may receive on the Trigger PLUS at maturity, if any. Any of these hedging or trading activities on

or prior to the pricing date could potentially affect the initial stock price and the trigger level and, therefore, could potentially increase the price that the final stock price must reach so that you do not suffer a loss on your initial investment in the Trigger PLUS. Additionally, these hedging or trading activities during the term of the Trigger PLUS, including on the valuation date, could adversely affect the final stock price and, accordingly, the amount of cash an investor will receive at maturity, if any. It is possible that such hedging or trading activities could result in substantial returns for us or our affiliates while the value of the Trigger PLUS declines.

Secondary trading may be limited. The Trigger PLUS will not be listed on a securities exchange. There may be little or no secondary market for the Trigger PLUS. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Trigger PLUS easily. JPMS may act as a market maker for the Trigger PLUS, but is not required to do so. Because we do not expect that other market makers will participate significantly in the secondary market for the Trigger PLUS, the price at which you may be able to trade your Trigger PLUS is likely to depend on the price, if any, at which JPMS is willing to buy the Trigger PLUS. If at any time JPMS or another agent does not act as a market maker, it is likely that there would be little or no secondary market for the Trigger PLUS.

The final terms and valuation of the Trigger PLUS will be provided in the pricing supplement. The final terms of the Trigger PLUS will be based on relevant market conditions when the terms of the Trigger PLUS are set and will be provided in the pricing supplement. In particular, each of JPMS’s estimated value and the maximum payment at maturity will be provided in the pricing supplement and each may be as low as the applicable minimum set forth on the cover of these preliminary terms. Accordingly, you should consider your potential investment in the Trigger PLUS based on the minimums for JPMS’s estimated value and the maximum payment at maturity.

The tax consequences of an investment in the Trigger PLUS are uncertain. There is no direct legal authority as to the proper U.S. federal income tax characterization of the Trigger PLUS, and we do not intend to request a ruling from the Internal Revenue Service (the “IRS”). The IRS might not accept, and a court might not uphold, the treatment of the Trigger PLUS described in “Additional Information About the Trigger PLUS—Additional Provisions—Tax considerations” in this document and in “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. MS-1-III. If the IRS were successful in asserting an alternative treatment for the Trigger PLUS, the timing and character of any income or loss on the Trigger PLUS could differ materially and adversely from our description herein. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Trigger PLUS, possibly with retroactive effect. You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. MS-1-III and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Trigger PLUS, including possible alternative treatments and the issues presented by this notice.

JPMS’s estimated value of the Trigger PLUS:

JPMS’s estimated value of the Trigger PLUS set forth on the cover of this document is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the Trigger PLUS, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the Trigger PLUS. JPMS’s estimated value does not represent a minimum price at which JPMS would be willing to buy your Trigger PLUS in any secondary market (if any exists) at any time. The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. For additional information, see “Risk Factors — JPMS’s estimated value is not determined by reference to credit spreads for our conventional fixed-rate debt.” The value of the derivative or derivatives underlying the economic terms of the Trigger PLUS is derived from JPMS’s internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, JPMS’s estimated value of the Trigger PLUS on the pricing date is based on market conditions and other relevant factors and assumptions existing at that time. See “Risk Factors — JPMS’s estimated value does not represent future values of the Trigger PLUS and may differ from others’ estimates.”

JPMS’s estimated value of the Trigger PLUS will be lower than the original issue price of the Trigger PLUS because costs associated with selling, structuring and hedging the Trigger PLUS are included in the original issue price of the Trigger PLUS. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the Trigger PLUS and the estimated cost of hedging our obligations under the Trigger PLUS. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the Trigger PLUS. See “Risk Factors — JPMS’s estimated value of the Trigger PLUS will be lower than the original issue price (price to public) of the Trigger PLUS” in this document.

Secondary market prices of the Trigger PLUS:

Tax considerations:

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. MS-1-III. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Trigger PLUS.

Based on current market conditions, in the opinion of our special tax counsel, Davis Polk & Wardwell LLP, your Trigger PLUS should be treated as “open transactions” that are not debt instruments for U.S. federal income tax purposes. Assuming this treatment is respected, the gain or loss on your Trigger PLUS should be treated as long-term capital gain or loss if you hold your Trigger PLUS for more than a year, whether or not you are an initial purchaser of Trigger PLUS at the issue price. However, the IRS or a court may not respect this treatment of the Trigger PLUS, in which case the timing and character of any income or loss on the

Trigger PLUS could be materially and adversely affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Trigger PLUS, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Trigger PLUS, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders—Additional Tax Consideration

Recently proposed Treasury regulations could impose a 30% (or lower treaty rate) withholding tax on amounts paid or deemed paid after December 31, 2015 that are treated as attributable to U.S.-source dividends on equities underlying financial instruments such as the Trigger PLUS. While it is not clear whether or in what form these regulations will be finalized, under recent Treasury guidance, these regulations would not apply to the Trigger PLUS. You should consult your tax adviser regarding the potential application of these proposed regulations.

Use of proceeds and hedging:

The net proceeds we receive from the sale of the Trigger PLUS will be used for general corporate purposes and, in part, by us or by one or more of our affiliates in connection with hedging our obligations under the Trigger PLUS.

The Trigger PLUS are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the Trigger PLUS. See “How the Trigger PLUS Work” in this document for an illustration of the risk-return profile of the Trigger PLUS and “Apple Inc. Overview” in this document for a description of the market exposure provided by the Trigger PLUS.

The original issue price of the Trigger PLUS is equal to JPMS’s estimated value of the Trigger PLUS plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the Trigger PLUS, plus the estimated cost of hedging our obligations under the Trigger PLUS.

Benefit plan investor considerations:

Supplemental plan of distribution:

Subject to regulatory constraints, JPMS intends to use its reasonable efforts to offer to purchase the Trigger PLUS in the secondary market, but is not required to do so.

We or our affiliate may enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the Trigger PLUS and JPMS and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions. See “— Use of proceeds and hedging” above and “Use of Proceeds and Hedging” on page PS-43 of the accompanying product supplement no. MS-1-III.
