EXPLANATORY NOTE

We filed our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 with the Securities and Exchange Commission (“SEC”) on May 3, 2013 (the “Original Filing”). We are filing this Amendment No. 1 on Form 10-Q/A (this “Amendment”) for the sole purpose of including corrected Exhibit 31(a), Exhibit 31(b) and Exhibit 32 certifications that were filed with the Original Filing in order to correctly identify the filing as a quarterly report on Form 10-Q. The certifications in the Original Filing incorrectly identified the filing as an annual report on Form 10‑K.

Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, and guidance provided by the staff of the SEC, this amendment contains the complete text of the Original Filing. Except with respect to appropriate revisions to Part II, Item 6 to reflect this Amendment as described above, we have not modified or updated other disclosures presented in the Original Filing. This Amendment does not amend, update or change the financial statements or any other disclosures in the Original Filing and does not reflect events occurring after the filing of the Original Filing. This Amendment should be read in conjunction with our other filings with the SEC subsequent to the filing of the Original Filing.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The interim unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared by Digi International Inc. (the “Company,” “Digi,” “we,” “our,” or “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted, pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto, including (but not limited to) the summary of significant accounting policies, presented in our Annual Report on Form 10-K for the year ended September 30, 2012 as filed with the SEC (“2012 Financial Statements”).

The condensed consolidated financial statements presented herein reflect, in the opinion of management, all adjustments which consist only of normal, recurring adjustments necessary for a fair statement of the condensed consolidated balance sheets and the condensed consolidated results of operations and cash flows for the periods presented. The condensed consolidated results of operations for any interim period are not necessarily indicative of results for the full year. The year-end condensed consolidated balance sheet data were derived from our 2012 Financial Statements, but do not include all disclosures required by U.S. GAAP.

Recently Issued Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2013-05, "Foreign Currency Matters (Topic 830); Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This guidance applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. We will adopt this guidance beginning with our fiscal quarter ending December 31, 2014. We are currently reviewing the provisions of ASU No. 2013-05 but do not expect it to have a material effect on our consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02, "Comprehensive Income (Topic 220); Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This updated guidance improves the reporting of significant items reclassified out of accumulated other comprehensive income and requires an entity to present, either on the face of the statement where net income is presented or in the notes, separately for each component of comprehensive income, the current period reclassifications out of accumulated other comprehensive income by the respective line items of net income affected by the reclassification. The updated guidance is effective prospectively for reporting periods beginning after December 15, 2012. We adopted this guidance beginning January 1, 2013. Other than requiring additional disclosures, the adoption did not have an effect on our consolidated financial statements.

In August 2012, the SEC adopted a rule mandated by the Dodd-Frank Act to require companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo or an adjoining country. The final rule applies to a company that uses minerals including tantalum, tin, gold or tungsten. The final rule requires companies to provide disclosure on a new form filed with the SEC, with the first specialized disclosure report due on May 31, 2014, for the 2013 calendar year, and annually on May 31 each year thereafter. We are currently evaluating the impact of adoption.

2. EARNINGS PER SHARE

Basic net income per common share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares of our stock result from dilutive common stock options, restricted stock units and shares purchased through our employee stock purchase plan.

The following table is a reconciliation of the numerators and denominators in the net income per common share calculations (in thousands, except per common share data):



	Three months ended March 31,				Six months ended March 31,
	2013		2012		2013		2012
Numerator:
Net income	$	1,000	$	2,122	$	2,230	$	2,846
Denominator:
Denominator for basic net income per common share — weighted average shares outstanding	26,138		25,709		26,163		25,674
Effect of dilutive securities:
Employee stock options, restricted stock units and employee stock purchase plan	338		496		311		498
Denominator for diluted net income per common share — adjusted weighted average shares	26,476		26,205		26,474		26,172
Net income per common share, basic	$	0.04	$	0.08	$	0.09	$	0.11
Net income per common share, diluted	$	0.04	$	0.08	$	0.08	$	0.11

Because their effect would be anti-dilutive, certain potentially dilutive shares related to stock options to purchase common shares were not included in the above computation of diluted earnings per common share. This is because the options’ exercise prices were greater than the average market price of our common shares. For the three and six month periods ended March 31, 2013, there were 3,263,692 and 2,502,985 potentially dilutive shares related to such stock options. For both the three and six month periods ended March 31, 2012, there were 1,798,213 potentially dilutive shares related to such stock options.

3. ACQUISITION

Etherios, Inc.

On October 31, 2012, we acquired Etherios, Inc. ("Etherios"), a privately held corporation. The total purchase price of $20.5 million included $13.7 million in cash (excluding cash acquired of $0.8 million) and $6.8 million represented by 715,571 shares of our common stock. The common stock issued was valued at $9.508 per common share based on a per share value calculated as the average market price of the common stock during the fifteen trading days prior to the closing.

Cash in the amount of $2.35 million was deposited to an escrow fund with a third party agent. Of the $2.35 million escrow, $0.3 million related to a holdback amount pending final determination of the unpaid debt and working capital as shown on the closing balance sheet. This holdback amount was paid in February 2013 as we had no changes to the closing balance sheet. An additional $2.05 million is held in escrow for a period not to exceed eighteen months from the date of closing to satisfy possible claims that may arise pursuant to specific representation and warranty sections of the stock purchase agreement. The escrowed amounts have been included in the determination of the purchase consideration on the date of acquisition as management expects that the representation and warranty matters is determinable beyond a reasonable doubt.

Costs related to the acquisition, which include legal, accounting, and valuation fees, in the amount of $0.2 million have been charged directly to operations and are included in general and administrative expense in our consolidated statement of operations for the sixth months ended March 31, 2013.

The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in the recognition of $17.1 million of goodwill. We believe that the acquisition resulted in the recognition of goodwill primarily because Etherios is a salesforce.com Platinum Partner and experienced in end user implementation of the

Table of Contents

3. ACQUISITION (Continued)

Salesforce Service Cloud. Although we believe the relationship with salesforce.com is important to us, it is not an exclusive relationship and requires Etherios to compete with others for business opportunities. Accordingly, we have determined that this relationship cannot be valued as a separate intangible asset of Etherios and as a result is a component of goodwill.

As salesforce.com has signaled its intent for the Service Cloud to be used as a means to monitor machines, we also believe that the acquisition of Etherios will further enhance our solutions offerings and provide another channel for net sales of our networking products.

Etherios' operating results are included in our consolidated results of operations from the date of acquisition. The consolidated balance sheet as of March 31, 2013 reflects the allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition.

The Etherios acquisition has been accounted for using the acquisition method of accounting which requires, among other things, that most assets acquired and liabilities assumed pursuant to the stock purchase agreement be recognized at fair value as of the acquisition date. Certain estimated values are not yet finalized (see below) and are subject to change, which could be significant. We will finalize the amounts recognized as information necessary to complete the analysis is obtained. We expect to finalize these amounts no later than the end of our third quarter of fiscal 2013. The following items remain subject to change:


•	amounts for contingent liabilities, pending the finalization of our review of the Etherios contingent liabilities;


•	certain tangible and intangible assets, pending the finalization of valuation procedures;


•	certain assets and liabilities pending the results of a comprehensive accounting policy consistency review; and


•	amounts for deferred tax assets and liabilities, pending the finalization of assets acquired, liabilities assumed and resulting goodwill.

The following table summarizes the values of Etherios assets acquired and liabilities assumed as of the acquisition date. To the extent previously discussed, such amounts are considered preliminary (in thousands):



Cash, including cash in escrow	$	13,696
Common stock	6,804
Total	$	20,500

Fair value of net tangible assets acquired	$	1,367
Identifiable intangible assets:
Existing customer relationships	1,400
Non-compete agreements	1,100
Trade name	440
Order backlog	360
Goodwill	17,120
Deferred tax liabilities related to identifiable intangibles	(1,287		)
Total	$	20,500

The weighted average useful life for all the identifiable intangibles listed above is 5.7 years. For purposes of determining fair value, the existing customer relationships identified above are assumed to have useful lives ranging between six to eight years, non-compete agreements are assumed to have useful lives of five years, the trade name is assumed to have a useful life of seven years, and the order backlog is assumed to have a useful life of one year. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangible assets. The identifiable intangible assets are amortized using the straight-line method which reflects the pattern in which the asset is expected to be consumed.

We have determined that the Etherios acquisition is not material to our consolidated results of operations or financial position. Therefore, pro forma financial information is not presented.

Inventories are stated at the lower of cost or market value, with cost determined using the first-in, first-out method.

5. MARKETABLE SECURITIES

Our marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. We analyze our available-for-sale marketable securities for impairment on an ongoing basis. When we perform this analysis, we consider factors such as the length of time and extent to which the securities have been in an unrealized loss position and the trend of any unrealized losses. We also consider whether an unrealized loss is a temporary loss or an other-than-temporary loss based on factors such as: (a) whether we have the intent to sell the security, or (b) whether it is more likely than not that we will be required to sell the security before its anticipated recovery, or (c) permanent impairment due to bankruptcy or insolvency.

In order to estimate the fair value for each security in our investment portfolio, where available, we obtain quoted market prices and trading activity for each security. We obtain relevant information from our investment advisor and also may review the financial solvency of certain security issuers if warranted. As of March 31, 2013, 61 of our 72 securities that we are holding were trading below our amortized cost basis. We determined each decline in value to be temporary based upon the above described factors. We expect to realize the fair value of these securities, plus accrued interest, either at the time of maturity or when the security is sold. All of our current holdings are classified as available-for-sale marketable securities and are recorded at fair value on our consolidated balance sheet with the unrealized gains and losses recorded in accumulated other comprehensive loss. All of our non-current marketable securities will mature in less than 3 years.

(2)	The aggregate related fair value of securities with unrealized losses as of September 30, 2012 was $34,503. These investments have been in an unrealized loss position for less than twelve months.

6. FAIR VALUE MEASUREMENTS

Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. This standard also establishes a hierarchy for inputs used in measuring fair value. This standard maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available in the circumstances. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Table of Contents

6. FAIR VALUE MEASUREMENTS (CONTINUED)

The hierarchy is broken down into the following three levels:


•	Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.


•	Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

•

Level 3 — Inputs are unobservable for the asset or liability and their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 may also include certain investment securities for which there is limited market activity or a decrease in the observability of market pricing for the investments, such that the determination of fair value requires significant judgment or estimation.

Fair value is applied to financial assets such as our marketable securities, which are classified and accounted for as available-for-sale. These items are stated at fair value at each reporting period using the above guidance.

The following tables provide information by level for financial assets that are measured at fair value on a recurring basis (in thousands):



			Fair Value Measurements at March 31, 2013 using:

Table of Contents

6. FAIR VALUE MEASUREMENTS (CONTINUED)

Cash equivalents are measured at fair value using quoted market prices in active markets for identical assets and are therefore classified as Level 1 assets. We value our Level 2 assets using inputs that are based on market indices of similar assets within an active market. There were no transfers in to or out of our Level 2 financial assets during the six months ended March 31, 2013.

We had no financial assets valued with Level 3 inputs as of March 31, 2013 nor did we purchase or sell any Level 3 financial assets during the six months ended March 31, 2013.

The use of different assumptions, applying different judgment to matters that are inherently subjective and changes in future market conditions could result in different estimates of fair value of our securities, currently and in the future. If market conditions deteriorate, we may incur impairment charges for securities in our investment portfolio.

Amortization expense was $1.1 million and $1.2 million for the three month periods ended March 31, 2013 and 2012, respectively. Amortization was $2.2 million and $2.4 million for the six month periods ended March 31, 2013 and 2012, respectively. Amortization expense is recorded on our consolidated statement of operations within cost of sales and in general and administrative expense. Estimated amortization expense related to identifiable intangible assets for the remainder of fiscal 2013 and the five succeeding fiscal years is (in thousands):

Table of Contents

7. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS (CONTINUED)

The goodwill related to the acquisition of Etherios is not tax deductible. Etherios is included in our single reporting segment for purposes of goodwill impairment testing. Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. An impairment could have a material effect on our consolidated balance sheet and results of operations. The calculation of asset impairment requires us to make assumptions about future cash flows and revenues. These assumptions require significant judgment and actual results may differ from assumed or estimated amounts. At June 30, 2012, our market capitalization was $264.3 million compared to our carrying value of $265.7 million. Our market capitalization plus our estimated control premium of 40% resulted in a fair value in excess of our carrying value by a margin of 39% and therefore no impairment was indicated.

8. INCOME TAXES

Income taxes have been provided at an overall effective rate of 18.0% and 37.2% for the six month periods ended March 31, 2013 and 2012, respectively. The overall effective tax rate includes the discrete items mentioned in the following paragraphs. Our effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and discrete events, such as settlements of audits.

In the second quarter of fiscal 2013, we recorded a discrete tax benefit of $0.4 million resulting from the enactment of legislation on January 2, 2013 extending the research and development tax credit for the last three quarters of fiscal 2012. In the first quarter of fiscal 2013, we recorded a discrete tax benefit of $0.1 million for the release of income tax reserves due to the expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions. These discrete tax benefits reduced our effective tax rate by 19.1 percentage points for the six month period ended March 31, 2013.

In the first quarter of fiscal 2012, we recorded a discrete tax benefit of $0.1 million for the release of income tax reserves due to the expiration of statutes of limitation from various U.S. tax jurisdictions. This discrete tax benefit reduced our effective tax rate by 2.7 percentage points for the six month period ended March 31, 2012.

The effective tax rate for the first half of fiscal 2012, before consideration of the impact of the discrete tax benefit, was higher than the Federal statutory rate primarily due to state income taxes, lower domestic tax benefits and increases in certain foreign tax reserves.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):




Unrecognized tax benefits as of September 30, 2012	$	2,720
Increases related to:
Prior year income tax positions	202
Decreases related to:
Expiration of statute of limitations	(98		)
Unrecognized tax benefits as of March 31, 2013	$	2,824

The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate is $2.8 million. We expect that it is reasonably possible that the total amounts of unrecognized tax benefits will increase approximately $0.2 million over the next 12 months due to increases in current year reserves, partially offset by the expiration of the statute of limitations.

We recognize interest and penalties related to income tax matters in income tax expense. During both the six month periods ended March 31, 2013 and 2012, there were insignificant amounts of interest and penalties related to income tax matters in income tax expense. We had accrued interest and penalties related to unrecognized tax benefits as of March 31, 2013 and September 30, 2012 of $0.5 million and $0.6 million, respectively. Our long-term income taxes payable on our condensed consolidated balance sheets includes these accrued interest and penalties in addition to the unrecognized tax benefits in the table above.

At March 31, 2013, we had approximately $23.4 million of accumulated undistributed foreign earnings, for which we have not accrued additional U.S. tax. Our policy is to reinvest earnings of our foreign subsidiaries indefinitely to fund current operations and provide for future international expansion opportunities, and only repatriate earnings to the extent that U.S. taxes have already been recorded. Although we have no current need to do so, if we change our assertion that we do not intend to repatriate additional undistributed foreign earnings for cash requirements in the United States, we would have to accrue applicable taxes. The amount of any taxes and the application of any tax credits would be determined based on the income tax

Table of Contents

8. INCOME TAXES (CONTINUED)

laws at the time of such repatriation. Under current tax laws, we estimate the unrecognized deferred tax liability to be in the range of $2.5 million to $3.5 million which could have a material impact on our current consolidated balance sheet, results of operations and cash flows.

We operate in multiple tax jurisdictions both in the U.S. and outside of the U.S. Accordingly, we must determine the appropriate allocation of income to each of these jurisdictions. This determination requires us to make several estimates and assumptions. Tax audits associated with the allocation of this income, and other complex issues, may require an extended period of time to resolve and may result in adjustments to our income tax balances in those years that are material to our consolidated balance sheet and results of operations. We are no longer subject to income tax examination for tax years prior to fiscal 2009 in the case of U.S. federal tax authorities and prior to fiscal 2008 for non-U.S. income tax authorities. For state taxing authorities, consisting primarily of Minnesota, California and Texas, we are no longer subject to income tax examination for tax years generally before fiscal 2008.

9. PRODUCT WARRANTY OBLIGATION

In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally range from one to five years. We typically have the option to either repair or replace products we deem defective with regard to material or workmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure the adequacy of the warranty accrual.

The following table summarizes the activity associated with the product warranty accrual (in thousands) and is included on our Condensed Consolidated Balance Sheets as its own line item within current liabilities:



	Balance at		Warranties		Settlements			Balance at
Period	January 1		issued		made			March 31

We are not responsible for, and do not warrant that, custom software versions, created by original equipment manufacturer (OEM) customers based upon our software source code, will function in a particular way, will conform to any specifications or are fit for any particular purpose. Further, we do not indemnify these customers from any third-party liability as it relates to or arises from any customization or modifications made by the OEM customer.

10. CONTINGENCIES

Patent Infringement Lawsuits

On May 29, 2012, U.S. Ethernet Innovations, LLC ("USEI") filed a patent infringement lawsuit against us in federal court in the Eastern District of Texas. The lawsuit included allegations against us and one other company pertaining to the infringement of four patents related to Ethernet technology. On April 22, 2013, we announced the settlement of this patent infringement lawsuit for $1.5 million, which has been recorded in general and administrative expense on our Condensed Consolidated Statement of Operations and on our Condensed Consolidated Balance Sheet at March 31, 2013. The settlement fully resolves the claims by USEI with no future payment obligations. Net of taxes, the settlement was $1.0 million and therefore reduced earnings per diluted share for the second quarter of fiscal 2013 by approximately $0.04.

On May 11, 2010, SIPCO, LLC filed a complaint naming us as a defendant in federal court in the Eastern District of Texas. This claim subsequently was moved to the Northern District of Georgia. The complaint included allegations against us and five other companies pertaining to the infringement of SIPCO's patents by wireless mesh networking and multi-port networking

10. CONTINGENCIES (CONTINUED)

products. On October 23, 2012, we settled the lawsuit for a payment of $500,000, which was recorded during the fourth quarter of fiscal 2012, and we entered into a royalty-bearing license agreement for future sales of licensed products sold during the term of the agreement through 2018. We do not expect this license agreement to have a material impact on our consolidated financial statements in the future.

In addition to the matters discussed above, in the normal course of business, we are subject to various claims and litigation. There can be no assurance that any claims by third parties, if proven to have merit, will not materially adversely affect our business, liquidity or financial condition. With the exception of certain capitalized legal costs related to patents and trademarks, we expense our legal costs as incurred and record them in general and administrative expense.

11. RESTRUCTURING

U.S. Restructuring

On April 26, 2012, we announced our intention to restructure certain of our operations. We recorded $1.0 million of restructuring charges on a pre-tax basis. The restructuring relates primarily to changes being implemented to focus on a shift in our business to more aggressively sell end-to-end M2M solutions. As a result of this restructuring, we eliminated employment positions in our work force of 30 employees at a cost of $0.6 million for severance and have moved to hire new employees or re-assign existing employees into newly created positions. We also expect to incur expenses from vacating facilities in Davis, California and Huntington Beach, California at a cost of approximately $0.4 million. The payments associated with these charges and all the actions associated with the restructuring were completed during the second quarter of fiscal 2013.

Below is listed a summary of the restructuring charges and other activity within the restructuring accrual (in thousands):



	Employee Termination Costs			Other			Total
Restructuring charge at April 26, 2012	$	568		$	395		$	963

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Our management’s discussion and analysis should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2012, as well as our reports on Forms 10-Q and 8-K and other publicly available information.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Form 10-Q contains certain statements that are “forward-looking statements” as that term is defined under the Private Securities Litigation Reform Act of 1995, and within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

The words “assume,” “believe,” “anticipate,” “intend,” “estimate,” “target,” “may,” “will,” “expect,” “plan,” “project,” “should,” or “continue” or the negative thereof or other variations thereon or similar terminology, which are predictions of or indicate future events and trends and which do not relate to historical matters, identify forward-looking statements. Among other items, these statements relate to expectations of the business environment in which we operate, projections of future performance, perceived marketplace opportunities and statements regarding our mission and vision. Such statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, including risks related to the highly competitive market in which our company operates, rapid changes in technologies that may displace products sold by us, declining prices of networking products, our reliance on distributors and other third parties to sell our products, delays in product development efforts, uncertainty in user acceptance of our products, the ongoing shift of our sales efforts to focus more on the delivery of broader based solutions which can be a more complex sales process, has not been a historical sales focus of our company and can involve longer sales cycles than the sale of our legacy hardware products, the ability to integrate our products and services with those of other parties in a commercially accepted manner, potential liabilities that can arise if any of our products have design or manufacturing defects, our ability to defend or settle satisfactorily any litigation, uncertainty in global economic conditions and economic conditions within particular regions of the world which could negatively affect product demand and the financial solvency of customers and suppliers, the impact of natural disasters and other events beyond our control that could negatively impact our supply chain and customers, the ability to achieve the anticipated benefits and synergies associated with acquisitions, such as our recently announced purchase of Etherios, Inc., and changes in our level of revenue or profitability which can fluctuate for many reasons beyond our control. These and other risks, uncertainties and assumptions identified from time to time in our filings with the United States Securities and Exchange Commission, including without limitation, our annual report on Form 10-K for the year ended September 30, 2012 and subsequent quarterly reports on Form 10-Q and other filings, could cause the company’s future results to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Many of such factors are beyond our ability to control or predict. These forward-looking statements speak only as of the date for which they are made. We disclaim any intent or obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, the disclosure of contingent assets and liabilities and the values of purchased assets and assumed liabilities in acquisitions. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

A description of our critical accounting policies and estimates was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended September 30, 2012. There have been no material changes to our critical accounting policies as disclosed in that report.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

OVERVIEW

We are a leading provider of machine to machine (M2M) networking products and solutions that enable the connection, monitoring and control of local or remote physical assets by electronic means. These networking products and solutions can connect communication hardware to a physical asset and convey information about the asset's status and performance, which can be sent to a computer system and used to improve or automate one or more processes. Increasingly these products and solutions are being deployed via wireless networks as wireless communications become more and more prevalent. Our products are deployed by a wide range of businesses and institutions. We compete for customers on the basis of existing and planned product features, service and software application capabilities, company reputation, brand recognition, technical support, relationships with partners, quality and reliability, product development capabilities, price and availability.

Net sales were $48.2 million for the second quarter of fiscal 2013, compared to $49.0 million for the second quarter of fiscal 2012, a decrease of $0.8 million. The results for the second quarter of fiscal 2013 included the net sales from Etherios' consulting services of $2.4 million in North America. We believe that the acquisition of Etherios will further enhance our solutions offerings and provide another channel for net sales of our networking products. North American net sales decreased by $0.4 million, or 1.3%, and international net sales decreased by $0.4 million, or 2.2%, in the second quarter of fiscal 2013 compared to the comparable quarter a year ago. In the second quarter of fiscal 2012, we recorded revenue of approximately $3.0 million that was delayed from the first quarter of fiscal 2012 as a result of the flooding in Thailand that took place in October 2011, impacting the operations of our contract manufacturer located near Bangkok, Thailand.

Net income was $1.0 million in the second quarter of fiscal 2013, or $0.04 per diluted share, compared to $2.1 million, or $0.08 per diluted share, in the second quarter of fiscal 2012. Net income in the second quarter of fiscal 2013 included the settlement described below of $1.0 million, net of taxes, which reduced earnings per diluted share by approximately $0.04. This was partially offset by a tax benefit of $0.4 million, or $0.01 per diluted share, resulting from the enactment of legislation extending the research and development tax credit that allowed us to record tax credits for the last three quarters of fiscal 2012 in the second quarter of fiscal 2013, based on the enactment date of January 2, 2013.

On April 22, 2013, we announced the settlement of a patent infringement lawsuit with U.S. Ethernet Innovations, LLC for $1.5 million ($1.0 million, net of taxes). We recorded the pre-tax settlement of $1.5 million in general and administrative expense in the second quarter of fiscal 2013 (See Note 10 to our Condensed Consolidated Financial Statements).

NET SALES

Net sales decreased by $0.8 million, or 1.7%, for the three months ended March 31, 2013 compared to the three months ended March 31, 2012. Net sales decreased $0.5 million, or 0.5%, for the six months ended March 31, 2013 compared to the six months ended March 31, 2012. Net sales for the three and six month periods ended March 31, 2013 included Etherios net sales from the date of acquisition of $2.4 million and $3.9 million, respectively. The net sales of our mature products decreased at a faster rate than the increases in net sales of our growth and services products. In the second quarter of fiscal 2012, we recorded revenue of approximately $3.0 million that was delayed from the first quarter of fiscal 2012 as a result of the flooding in Thailand that took place in October 2011, impacting the operations of our contract manufacturer located near Bangkok, Thailand. We did not experience a significant change in net sales as a result of pricing during the three and six month periods ended March 31, 2013.

Beginning in the second quarter of fiscal 2013, we are no longer measuring our products and services in the embedded and non-embedded product categories. We are now measuring our net sales by growth products and services and mature product categories as we believe that this is a more meaningful presentation and reflects how we are viewing and measuring our revenue.

Our growth products and services portfolio includes all wireless products, as well as the ARM-based embedded module product line, which leverages the Device Cloud by Etherios™ ((Device Cloud) formerly known as the iDigi® platform) with both wired and wireless connectivity. The services portfolio includes our wireless design solutions, application consulting services, Etherios consulting services, and the Device Cloud platform. Growth products and services increased by $0.8 million and $2.8 million for the three and six month periods ended March 31 2013 as compared to the same periods a year ago. The growth products and services portfolio includes net sales of Etherios' consulting services of $2.4 million and $3.9 million for the three and six month periods ended March 31, 2013. Our mature products portfolio includes all wired products, except for ARM-based embedded modules which are included in growth products. Net sales of our mature products decreased as expected for both the three and six month periods ended March 31, 2013 as compared to the same periods a year ago.

We believe that our serial servers, Rabbit-branded modules, chips and USB products are mature products and we expect that net sales of these products will continue to decrease in the future as they are near the end of their product life cycles.

Our Wireless products category comprised 43.2% and 44.6% of our total net sales for the three and six months ended March 31, 2013, respectively, and 44.5% and 43.5% of our net sales for the three and six months ended March 31, 2012, respectively. The Wireless products category includes all wireless products, in addition to wireless design services, application consulting services and the Device Cloud platform. The Other category includes consulting services revenue from Etherios.

As we continue to transition to a wireless products and solutions-based sales organization, we may experience uneven demand, that may cause fluctuations in revenue in future quarters.

Net Sales by Geographic Location

Net sales in North America decreased by $0.4 million and $1.2 million for the three and six months ended March 31, 2013, respectively compared to the same periods a year ago as the net sales of our mature products decreased at a faster rate than the increases in net sales of our growth and services products. Net sales of Etherios for the three and six months ended March 31, 2013 were $2.4 million and $3.9 million, respectively.

Net sales in Europe, Middle East & Africa (“EMEA”) decreased by $0.2 million for the three months ended March 31, 2013 compared to the same period a year ago primarily due to decreases in net sales of cellular and embedded modules. EMEA net sales for the six months ended March 31, 2013 compared to the same period a year ago increased by $0.2 million primarily due to an increase in cellular product net sales.

Net sales in Asia countries increased by $0.1 million and $1.0 million for the three and six month periods ended March 31, 2013, respectively, compared to the same periods a year ago. This was primarily due to an increase in project-based revenue.

Net sales in Latin America decreased by $0.3 million and $0.5 million for the three and six month periods ended March 31, 2013, respectively, compared to the same periods a year ago primarily due to reduction in cellular product net sales.

The fluctuation of foreign currency rates had an unfavorable impact on net sales of $0.1 million for the three month period ended March 31, 2013, when compared to the same periods a year ago, primarily related to the weakening of the Yen compared to the U.S. dollar. For the six months ended March 31, 2013 as compared to the same period a year ago, the unfavorable impact on net sales was $0.3 million due to the weakening of the Euro and the Yen compared to the U.S. dollar.

GROSS MARGIN

Gross margins were 51.8% and 51.9% for the three and six month periods ended March 31, 2013, respectively compared to gross margins of 52.6% and 52.5% for the three and six month periods ended March 31, 2012, respectively. The gross margin decreased for the three and six months ended March 31, 2013 by 0.8 percentage points and 0.6 percentage points, respectively

Table of Contents

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

primarily due to the inclusion of gross margins from Etherios' consulting services. The margins on these services are generally lower than our products' margins.

OPERATING EXPENSES

Operating expenses increased by $2.2 million and $1.4 million for the three and six month periods ended March 31, 2013 as compared to the same periods a year ago. Incremental operating expenses for Etherios for the three and six month periods ended March 31, 2013 were $1.2 million and $1.9 million, respectively. The settlement of the patent infringement lawsuit of $1.5 million ($1.0 million, net of taxes) is included in general and administrative expenses for the three and six months ended March 31, 2013. This was partially offset by cost containment measures that were put in place to achieve targeted expense levels.

The following summarizes our total operating expenses, in dollars and as a percentage of net sales:



	Three months ended March 31,									$ incr.			Six months ended March 31,									$ incr.

Sales and marketing expenses for the three and six months ended March 31, 2013 as compared to the same periods a year ago increased by $0.1 million and $0.2 million, respectively, primarily related to an increase in compensation-related expense partially offset by a decrease in outside services expense.

Research and development expenses remained mostly unchanged for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. Research and development expenses decreased $0.8 million for the six months ended March 31, 2013 as compared to the six months ended March 31, 2012 due primarily to a decrease of $0.5 million in outside services and a decrease of $0.3 million in other research and development expenses.

General and administrative expenses increased $2.2 million for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The increase was primarily related to a patent infringement settlement of $1.5 million ($1.0 million, net of taxes) (see Note 10 to our Condensed Consolidated Financial Statements) and an increase of $0.3 million related to a prior year reversal of a reserve for the NetSilicon IPO litigation as our insurers paid on our behalf to the plaintiffs the full amount of the settlement share allocated to us. In addition, professional fees increased by $0.3 million. General and administrative expenses increased by $2.3 million for the six months ended March 31, 2013 as compared to the six months ended March 31, 2012 due primarily to the patent infringement settlement mentioned above of $1.5 million ($1.0 million, net of taxes), the $0.3 million prior year reversal for the NetSilicon IPO litigation as previously described and an increase of $0.6 million for professional fees.

Restructuring expense was $0.1 million and $0.3 million for the three and six month periods ended March 31, 2012, respectively related to the Breisach, Germany restructuring announced July 21, 2011.

OTHER INCOME (EXPENSE), NET

Other income (expense), net increased by $0.4 million for the both the three and six month periods ended March 31, 2013 compared to the same periods a year ago primarily due to unrealized exchange gains resulting from remeasuring net assets held in non-functional currencies to local currencies, and realized exchange gains. We recorded a gain on the sale of an investment of $0.1 million in the first quarter of fiscal 2012.

INCOME TAXES

Table of Contents

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

In the second quarter of fiscal 2013, we recorded a discrete tax benefit of $0.4 million resulting from the enactment of legislation on January 2, 2013, extending the research and development tax credit for the last three quarters of fiscal 2012. In the first quarter of fiscal 2013, we recorded a discrete tax benefit of $0.1 million for the release of income tax reserves due to the expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions. These discrete tax benefits reduced our effective tax rate by 19.1 percentage points for the six month period ended March 31, 2013.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations and capital expenditures principally with funds generated from operations. At March 31, 2013, we had cash, cash equivalents and short-term marketable securities of $79.8 million compared to $118.6 million at September 30, 2012. Our working capital (total current assets less total current liabilities) was $119.6 million at March 31, 2013 and $155.4 million at September 30, 2012. The decreases in both the liquid assets and the working capital resulted primarily from an increase of $20.1 million in long-term marketable securities from September 30. 2012 to March 31, 2013 as we modified our investment policy to allow purchases of certificates of deposits for up to a three year term. In addition we spent $12.9 million, net of cash acquired for the acquisition of Etherios, and $6.8 million on the purchase of our treasury stock. We presently anticipate total fiscal 2013 capital expenditures will be approximately $3.9 million.

Reconciliation of Changes in Operating Assets and Liabilities:

Accounts receivable	$	1,315		$	1,151		$	164

Accrued expenses	379			862			(483		)
Changes in operating assets and liabilities	$	(4,103	)	$	(2,720	)	$	(1,383	)

Net cash provided by operating activities was $3.4 million for the six months ended March 31, 2013 as compared to $6.1 million for the six months ended March 31, 2012, a net decrease of $2.7 million. This is primarily due to a reduction for changes in working capital of $1.4 million, a decrease in net income of $0.6 million, a decrease in the restructuring accrual of $0.3 million and a decrease of $0.4 million for inventory obsolescence and other reconciling items. The decrease of $1.4 million for working capital was due to lower bonus payouts relating to the fiscal 2012 bonus plan in the first quarter of fiscal 2013 compared to the prior fiscal year, a decrease in accounts payable balances due to less inventory purchases, additional prepaid expenses and income taxes receivable.

Net cash used in investing activities was $14.2 million during the six months ended March 31, 2013 as compared to $13.6 million for the six months ended March 31, 2012, a net increase of $0.6 million. During the first six months of fiscal 2013 as compared to the first six months of fiscal 2012, we had net proceeds from maturities of marketable securities of $0.8 million in the first half of fiscal 2013 offset by net purchases of $11.1 million in the first half of fiscal 2012 and fewer expenditures for net capital equipment of $0.6 million. This was partially offset by an expenditure of $12.9 million, net of cash acquired, for the purchase of Etherios, Inc.

Cash used by financing activities was $5.9 million for the six months ended March 31, 2013 and cash provided by financing activities was $1.2 million for the six months ended March 31, 2012, a net decrease of $7.1 million. The majority of this decrease was due to our purchase of treasury stock of $6.8 million during the six months ended March 31, 2013.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

We expect positive cash flows from operations and believe that our current cash, cash equivalents and marketable securities balances, cash generated from operations and our ability to secure debt and/or equity financing will be sufficient to fund our business operations and capital expenditures for the next twelve months and beyond. On July 25, 2012 our Board of Directors authorized a program to repurchase up to $20.0 million of our common stock. We began repurchasing our common stock on the open market in the first quarter of fiscal 2013. This repurchase authorization expires on September 30, 2013. During the first six months of fiscal 2013, we repurchased 707,654 shares for $6.8 million.

At March 31, 2013, our total cash and cash equivalents and short-term marketable securities balance was $79.8 million. This balance includes approximately $32.9 million of cash and cash equivalents held by our controlled foreign subsidiaries of which $23.4 million represents accumulated undistributed foreign earnings. Although we have no current need to do so, if we change our assertion that we do not intend to repatriate additional undistributed foreign earnings for cash requirements in the United States, we would have to accrue applicable taxes. The amount of any taxes and the application of any tax credits would be determined based on the income tax laws at the time of such repatriation. Under current tax laws, we estimate the unrecognized deferred tax liability to be in the range of $2.5 million to $3.5 million which could have a material impact on our current consolidated balance sheet, results of operations and cash flows.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In August 2012, the U.S. Securities and Exchange Commission (the “SEC”) adopted a rule mandated by the Dodd-Frank Act to require companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo or an adjoining country. The final rule applies to a company that uses minerals including tantalum, tin, gold or tungsten. The final rule requires companies to provide disclosure on a new form filed with the SEC, with the first specialized disclosure report due on May 31, 2014, for the 2013 calendar year, and annually on May 31 each year thereafter. We are currently evaluating the impact of adoption.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

Our exposure to interest rate risk relates primarily to our investment portfolio. Our marketable securities are classified as available-for-sale and are carried at fair value. Marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. Our investment policy specifies the types of eligible investments and minimum credit quality of our investments, as well as diversification and concentration limits which mitigate our risk. We do not use derivative financial instruments to hedge against interest rate risk because the majority of our investments mature in less than a year.

FOREIGN CURRENCY RISK

We have transactions that are executed in the U.S. Dollar, British Pound, Euro, Japanese Yen and Indian Rupee. As a result, we are exposed to foreign currency transaction risk associated with certain sales transactions being denominated in Euros, British Pounds, Japanese Yen or Indian Rupees, and foreign currency translation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars for consolidation. We have not implemented a formal hedging strategy to reduce foreign currency risk.

For the six months ended March 31, 2013 and 2012, we had approximately $39.6 million and $38.9 million, respectively, of net sales to foreign customers including export sales. Of these sales, $11.5 million and $12.4 million, respectively, were denominated in foreign currency, predominantly Euros and British Pounds. In future periods, we expect a significant portion of sales will continue to be made in both Euros and British Pounds.

The table below compares the average monthly exchange rates of the Euro, British Pound, Japanese Yen and Indian Rupee to the U.S. Dollar:



	Six months ended March 31,		% increase
	2013	2012	(decrease)
Euro	1.3087	1.3297	(1.6	)%
British Pound	1.5804	1.5711	0.6	%
Japanese Yen	0.0116	0.0128	(9.4	)%
Indian Rupee	0.0185	0.0196	(5.6	)%

A 10% change from the first six months of fiscal year 2013 average exchange rate for the Euro, British Pound, Japanese Yen and Indian Rupee to the U.S. Dollar would have resulted in a 1.2% increase or decrease in net sales and a 1.9% increase or decrease in stockholders’ equity due to foreign currency translation. The above analysis does not take into consideration any pricing adjustments we might consider in response to changes in such exchange rates.

CREDIT RISK

We have some exposure to credit risk related to our accounts receivable portfolio. Exposure to credit risk is controlled through regular monitoring of customer financial status, credit limits and collaboration with sales management on customer contacts to facilitate payment.

Investments are made in accordance with our investment policy and consist of certificates of deposit, commercial paper, money market funds, government municipal bonds and corporate bonds. We may have some credit exposure related to the fair value of our securities, which could change based on changes in market conditions. If market conditions deteriorate or if these securities experience credit rating downgrades, we may incur impairment charges for securities in our investment portfolio. All of our securities are held domestically.

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of the principal executive officer and principal financial officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)). Based on this evaluation, the principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There was no change in our internal control over financial reporting during our most recently completed fiscal quarter that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The disclosures set forth in Note 10 to the Condensed Consolidated Financial Statements in Part I, Item 1 of this Form 10-Q are incorporated herein by reference.

ITEM 1A. RISK FACTORS

Except as noted below, there have been no material changes in our risk factors from those previously disclosed in Item 1A of Part I of our Annual Report on Form 10-K for the year ended September 30, 2012.

We are subject to various cybersecurity risks, which are particularly acute in the cloud-based technologies operated by us and other third parties that form a part of our solutions, that may increase our costs and could damage our brand and reputation.

As we continue to direct a substantial portion of our sales and development efforts toward broader based M2M solutions, including the Device Cloud by Etherios™, we expect to store, convey and potentially process increasing amounts of data produced by customer devices. This data may include confidential or proprietary information, intellectual property or personally identifiable information of our customers or other third parties with whom they do business. It is important for us to maintain solutions and related infrastructure that are perceived by our customers and other parties with whom we do business to provide a reasonable level of reliability and security. Despite available security measures and other precautions, the infrastructure and transmission methods used by our products and services may be vulnerable to interception, attack or other disruptive problems. Continued high-profile data breaches at other companies evidence an external environment that is becoming increasingly hostile to information security. Improper disclosure of data or perception that our data security is insufficient could harm our reputation, give rise to legal proceedings, or subject our company to liability under laws that protect data, any of which could result in increased costs and loss of revenue.

If a cyberattack or other security incident were to allow unauthorized access to or modification of our customers' data or our own data, whether due to a failure with our systems or related systems operated by third parties, we could suffer damage to our brand and reputation. The costs we would incur to address and fix these incidents would increase our expenses. These types of security incidents could also lead to lawsuits, regulatory investigations and increased legal liability, including in some cases contractual costs related to customer notification and fraud monitoring. Further, as regulatory focus on privacy and data security issues continues to increase and worldwide laws and regulations concerning the protection of information become more complex, the potential risks and costs of compliance to our business will intensify.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On July 25, 2012 our Board of Directors authorized a new program to repurchase up to $20.0 million of our common stock and terminated the prior repurchase authorization. This repurchase authorization expires on September 30, 2013. During the first quarter of fiscal 2013, we began to repurchase our common stock in the open market. The following table presents our repurchases during the second quarter of fiscal 2013:



Period	Total Number of Shares Purchased	Average Price Paid per Share	Total Number of Shares Purchased as Part of a Publicly Announced Program	Maximum Dollar Value of Shares that May Yet Be Purchased Under the Program
January 1, 2013 - January 31, 2013	86,532	$9.67	86,532	$14,839,445.58
