NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Unaudited Interim Financial Information —The accompanying unaudited, condensed consolidated financial statements have been prepared according to the rules and regulations of the United States (the “U.S.”) Securities and Exchange Commission (“SEC”) and, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of the condensed consolidated balance sheets, condensed consolidated statements of operations, condensed consolidated statement of comprehensive (loss) income, condensed consolidated statements of stockholders' equity and condensed consolidated statements of cash flows of MACOM Technology Solutions Holdings, Inc. (“MACOM”, the “Company”, “us”, “we” or “our”) for the periods presented. We prepare our interim financial information using the same accounting principles we use for our annual audited consolidated financial statements. Certain information and note disclosures normally included in the annual audited consolidated financial statements have been condensed or omitted in accordance with prescribed SEC rules. We believe that the disclosures made in our condensed consolidated financial statements and the accompanying notes are adequate to make the information presented not misleading.

The consolidated balance sheet at September 30, 2016 is as reported in our audited consolidated financial statements as of that date. Our accounting policies are described in the notes to our September 30, 2016 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended September 30, 2016 filed with the SEC on November 17, 2016 . We recommend that the financial statements included in this Quarterly Report on Form 10-Q be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for our fiscal year ended September 30, 2016 .

Principles of Consolidation— We have one reportable segment, semiconductors and modules. The accompanying consolidated financial statements include our accounts and the accounts of our majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

We have a 52 or 53-week fiscal year ending on the Friday closest to the last day of September. The fiscal years 2017 and 2016 include 52 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we include the extra week arising in our fiscal years in the first quarter.

Use of Estimates —The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported amounts of revenue and expenses during the reporting periods, and the disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, we base estimates and assumptions on historical experience, currently available information and various other factors that management believes to be reasonable under the circumstances. Actual results may differ materially from these estimates and assumptions.

Recent Accounting Pronouncements —Our Recent Accounting Pronouncements are described in the notes to our September 30, 2016 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended September 30, 2016 .

In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments , which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Acquirers will now recognize measurement-period adjustments during the period in which they determine the amount of the adjustment. This ASU is effective for annual and interim reporting periods beginning after December 15, 2015, and should be applied prospectively to adjustments for provisional amounts that occur after the effective date. The adoption of this guidance did not have a material impact on our consolidated financial statements.

2. ACQUISITIONS

Acquisition of Applied Micro Circuits Corporation— On January 26, 2017, we completed the acquisition of Applied Micro Circuits Corporation (“AppliedMicro”), a global provider of silicon solutions for next-generation cloud infrastructure and Cloud Data Centers, as well as connectivity products for edge, metro and long-haul communications equipment (the “AppliedMicro Acquisition”). We acquired AppliedMicro in order to expand our business in enterprise and Cloud Data Center applications. In connection with the AppliedMicro Acquisition, we acquired all of the outstanding common stock of AppliedMicro for total consideration of $695.4 million , which included cash paid of $287.1 million , less $56.8 million of cash acquired, and equity issued at a fair value of $465.1 million . In conjunction with the equity issued, we granted vested out-of-money stock options and unvested restricted stock units to replace outstanding vested out-of-money stock options and unvested restricted stock units of AppliedMicro. The total fair value of granted vested out-of-money stock options and unvested restricted stock units was $14.5 million , of which $9.3 million was attributable to pre-combination service and was included in the total consideration transferred. We funded the AppliedMicro Acquisition with cash on hand and short term investments. For the three and nine months ended June 30, 2017 , we recorded transaction costs of $0.1 million and $11.9 million , respectively. We recorded transaction costs related to the acquisition in selling, general and administrative expense, except for $ 1.0 million related to equity issuance costs which was recorded to additional paid in capital. The AppliedMicro Acquisition was accounted for as a stock purchase and the operations of AppliedMicro have been included in our consolidated financial statements since the date of acquisition.

We recognized the AppliedMicro assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for AppliedMicro has been allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair value at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which will be tax deductible.

The purchase accounting is preliminary and subject to completion including certain fair value measurements, particularly the finalization of the valuation assessment of the acquired tangible and intangible assets. The adjustments arising from the completion of the outstanding matters may materially affect the preliminary purchase accounting.

In connection with the acquisition of AppliedMicro, we entered into a plan to divest a portion of AppliedMicro's business specifically related to its compute business (the "Compute business"). Accordingly, these assets and liabilities are accounted for as discontinued operations and classified as assets and liabilities held for sale.

The following table summarizes the total estimated acquisition consideration (in thousands):



Cash consideration paid to AppliedMicro common stockholders	$	287,060

Acquisition of FiBest Limited— On December 9, 2015, we completed the acquisition of FiBest Limited (“FiBest”) a Japan-based merchant market component supplier of optical sub-assemblies (“FiBest Acquisition”). We acquired FiBest to expand our position in optical networking components. In connection with the FiBest Acquisition, all of the outstanding equity interests (including outstanding options) of FiBest were exchanged for aggregate consideration of $59.1 million including cash of $47.5 million and assumed debt of $11.6 million . We funded the FiBest Acquisition with cash on hand. There were no transaction costs recorded in the nine months ended June 30, 2017 . For the nine months ended July 1, 2016 we recorded transaction costs of $2.7 million as selling, general and administrative expenses related to this acquisition. The FiBest Acquisition was accounted for as a stock purchase and the operations of FiBest have been included in our consolidated financial statements since the date of acquisition.

We recognized the FiBest assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for FiBest has been allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which is tax deductible.

During the fiscal quarter ended December 30, 2016, we recorded an adjustment of $0.2 million primarily related to other liabilities and an adjustment of the deferred tax liability associated with the FiBest Acquisition. We finalized our allocation of purchase price during the fiscal quarter ended December 30, 2016. The final allocation of purchase price as of December 30, 2016, is as follows (in thousands):

Acquisition of Aeroflex/Metelics Inc.— On December 14, 2015, we acquired Aeroflex/Metelics, Inc. (“Metelics”), a diode supplier for aggregate cash consideration of $38.0 million , subject to customary working capital and other adjustments (“Metelics Acquisition”). We acquired Metelics to expand our diode business. We funded the acquisition with cash on hand. The Metelics Acquisition was accounted for as a stock purchase and the operations of Metelics have been included in our consolidated financial statements since the date of acquisition. There were no transaction costs recorded in the nine months ended June 30, 2017 . For the nine months ended July 1, 2016 , we recorded transaction costs of $0.5 million as selling, general and administrative expenses related to this acquisition.

3. DISCONTINUED OPERATIONS

In connection with the acquisition of AppliedMicro, we announced a plan to divest its Compute business. As of June 30, 2017 , the Compute business is being actively marketed, negotiations are preliminary and we expect to complete any such divestment within twelve months from the date of acquisition. We are accounting for the business as a discontinued operation.

In August 2015, we sold our automotive business (the "Automotive Business") to Autoliv ASP Inc. (“Autoliv”), as the Automotive business was not consistent with our long-term strategic vision from both a growth and profitability perspective. The agreed consideration included $82.1 million in cash paid at closing and $18.0 million payable in eighteen months pending resolution of any contingencies as part of an indemnification agreement, plus the opportunity to receive up to an additional $30.0 million in cash based on achievement of revenue-based earnout targets through fiscal year 2019. Additionally, we entered into a consulting agreement pursuant to which we may provide Autoliv with certain non-design advisory services for a period of two years following the closing of the transaction for up to $15.0 million in cash (the "Consulting Agreement").

During the fiscal quarter ended March 31, 2017, we received $18.0 million , the full amount of the indemnification escrow. The remainder of the consideration to be received from Autoliv, if any, including any additional amounts related to the Consulting Agreement, will be accounted for in discontinued operations when the contingencies are finalized and the proceeds, if any, become realizable.

Other income recorded during the three and nine months ended June 30, 2017 and July 1, 2016 from the Automotive business related to the Consulting Agreement.

The accompanying consolidated statements of operations includes the following operating results related to these discontinued operations (in thousands):

4. INVESTMENTS

All investments are short term in nature and are invested in corporate bonds, restricted money market funds, commercial paper and agency bonds, and are classified as available-for-sale. Money market funds include restricted investments in mutual funds acquired in connection with the acquisition of AppliedMicro, which are expected to be liquidated during our fiscal quarter ending September 29, 2017. The amortized cost, gross unrealized holding gains or losses, and fair value of our investments by major investment type as of June 30, 2017 and September 30, 2016 are summarized in the tables below (in thousands):

Total investments	$	81,641	$	23,776

Available-for-sale investments are reported at fair value and as such, their associated unrealized gains and losses are reported as a separate component of stockholders’ equity within accumulated other comprehensive loss.

5. FAIR VALUE

We group our financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.

Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by us.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

We measure certain assets and liabilities at fair value on a recurring basis such as our financial instruments and derivatives. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three and nine months ended June 30, 2017 .

Money market funds are actively traded and consist of highly liquid investments with original maturities of 90 days or less . They are measured at their net asset value and classified as Level 1 assets. Corporate and agency bonds and commercial paper are categorized as Level 2 assets except where sufficient quoted prices exist in active markets, in which case such securities are categorized as Level 1 assets. These securities are valued using third-party pricing services. These services may use, for example, model-based pricing methods that utilize observable market data as inputs. We generally use quoted prices for recent trading activity of assets with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are generally classified as Level 2 assets. Broker dealer bids or quotes on securities with similar characteristics may also be used.

Assets and liabilities measured at fair value on a recurring basis consist of the following (in thousands):



	June 30, 2017

Common stock warrant liability	38,253		—		—		38,253
Total liabilities measured at fair value	$	39,101	$	—	$	—	$	39,101

As of June 30, 2017 and September 30, 2016 , the fair value of the common stock warrants has been estimated using a Black-Scholes option pricing model.

The quantitative information utilized in the fair value calculation of our Level 3 liabilities is as follows:



			Inputs
Liabilities	Valuation Technique	Unobservable Input	June 30, 2017	September 30, 2016
Contingent consideration	Discounted cash flow	Discount rate	3.5% - 10.7%	12.9%
		Probability of achievement	70% - 100%	75% - 100%
		Timing of cash flows	5 - 7 months	1 year

Warrant liability	Black-Scholes model	Volatility	41.8%	43.2%
		Discount rate	1.55%	1.14%
		Expected life	3.48 years	4.23 years
		Exercise price	$14.05	$14.05

The fair values of the contingent consideration liabilities were estimated based upon a risk-adjusted present value of the probability-weighted expected payments by us. Specifically, we considered base, upside and downside scenarios for the operating metrics upon which the contingent payments are to be based. Probabilities were assigned to each scenario and the probability weighted payments were discounted to present value using risk-adjusted discount rates.

The changes in liabilities with inputs classified within Level 3 of the fair value hierarchy consist of the following (in thousands):



	September 30, 2016		Net Realized/Unrealized Losses Included in Earnings		Purchases and Issuances		Sales and Settlements			June 30, 2017
Contingent consideration	$	848	$	46	$	1,701	$	(400	)	$	2,195

	October 2, 2015		Net Realized/Unrealized Losses Included in Earnings		Purchases and Issuances		Sales and Settlements			July 1, 2016
Contingent consideration	$	1,150	$	66	$	—	$	(400	)	$	816

Depreciation and amortization expense related to property, plant and equipment for the three and nine months ended July 1, 2016 was $5.7 million and $15.2 million , respectively.

8. DEBT

On May 8, 2014, we entered into a credit agreement (“Credit Agreement”) with a syndicate of lenders that provided for term loans in an aggregate principal amount of $350.0 million , which were scheduled to mature in May 2021 (“Initial Term Loans”) and a revolving credit facility of $100.0 million initially (as increased by the amendments described below, “Revolving Facility”). In February 2015, we executed an amendment to the Credit Agreement that increased our aggregate borrowing capacity under the Revolving Facility to $130 million . The Initial Term Loans were issued with an original issue discount of 0.75% , which is being amortized over the term of the Initial Term Loans using the straight-line method, which approximates the effective interest rate method.

On August 31, 2016, we entered into an amendment (“2016 Incremental Term Loan Amendment”) to our Credit Agreement which provided for incremental term loans in an aggregate principal amount of $250 million , which were scheduled to mature in May 2021 (“2016 Incremental Term Loans”). The terms of the 2016 Incremental Term Loans were identical to the terms of the Initial Term Loans, other than with respect to upfront fees, original issue discount and arrangement, structuring or similar fees payable in connection therewith. The 2016 Incremental Term Loans were issued with an original issue discount of 0.95% , which is being amortized over the term of the 2016 Incremental Term Loans using the straight-line method, which approximates the effective interest rate method.

On March 10, 2017, we entered into multiple amendments to our Credit Agreement (the "March 2017 Amendments"), which consisted of (i) the Second Incremental Amendment, by and among MACOM, Barclays Bank PLC and Goldman Sachs Bank USA, as administrative agent, (ii) the Refinancing Amendment, by and among MACOM, the lenders party thereto and Goldman Sachs Bank USA, as administrative agent and (iii) Amendment No. 4 to the Credit Agreement, by and among MACOM, the revolving credit lenders and Goldman Sachs Bank USA, as administrative agent. Pursuant to the March 2017 Amendments, we increased the revolving credit commitments available under our revolving credit facility by $30.0 million to $160.0 million . No amounts were drawn under the Revolving Facility on the closing date of the March 2017 Amendments or as of June 30, 2017 . In addition, pursuant to the March 2017 Amendments, our existing term loans were refinanced at a reduced interest rate.

Further, pursuant to the March 2017 Amendments, the Credit Agreement was amended to provide that the financial covenant under the Revolving Facility would only be tested if, as of the last date of any fiscal quarter, the aggregate amount outstanding under the Revolving Facility (other than with respect to (a) undrawn letters of credit in an amount not to exceed $5.0 million and (b) letters of credit that have been cash collateralized pursuant to the Credit Agreement) exceeds 35% of the revolving credit commitments under the Revolving Facility. Prior to the March 2017 Amendments, the threshold for testing the financial covenant was set at 25% of the revolving credit commitments under the Revolving Facility.

On May 19, 2017, we entered into two amendments to our Credit Agreement (the "May 2017 Amendments") which consisted of (i) the Second Refinancing Amendment, among MACOM, Morgan Stanley Senior Funding, Inc. and the other term lenders party thereto and Goldman Sachs Bank USA, as administrative agent (the "Second Refinancing Amendment"), and (ii) the Second Incremental Term Loan Amendment, among MACOM, Morgan Stanley Senior Funding, Inc. and the other lenders party thereto and Goldman Sachs Bank USA, as administrative agent (the "Second Incremental Term Loan Amendment").

Pursuant to the Second Refinancing Amendment, our existing term loans of $588.5 million were refinanced with a new tranche of term loans. The refinanced term loans will mature in May 2024 and bear interest at: (i) for LIBOR loans for any interest period, a rate per annum equal to the LIBOR rate as determined by the administrative agent, plus an applicable margin of 2.25% ; and (ii) for base rate loans, a rate per annum equal to the greater of (a) the prime rate quoted in the print edition of the Wall Street Journal, Money Rates Section, (b) the federal funds rate plus one-half of 1.00% and (c) the LIBOR rate applicable to a one-month interest period plus 1.00% (but, in each case, not less than 1.00% ), plus an applicable margin of 1.25% . The effective interest rate on our term loans was 3.5% as of June 30, 2017 .

Pursuant to the Second Incremental Term Loan Amendment, we borrowed an additional $100.0 million of incremental term loans (the "2017 Incremental Term Loans", together with the Initial Term Loans and the 2016 Incremental Term Loans, "Term Loans") on the same terms as the new tranche of term loans incurred pursuant to the Second Refinancing Amendment. The 2017 Incremental Term Loans and the new tranche of term B loans were issued with an original issue discount of 0.50% , which is being amortized over the term of the Second Refinancing Amendment using the straight-line method, which approximates the effective interest rate method.

We incurred $8.7 million in fees for the issuance of the Credit Agreement in May 2014, and $3.2 million in fees for the issuance of the 2016 Incremental Term Loan Amendment in August 2016, which were initially recorded as deferred financing costs and are being amortized over the initial life of the Credit Agreement as interest expense. In March 2017, we incurred an additional $1.0 million in fees for the issuance of the March 2017 Amendments, and in May 2017, we incurred an additional $11.1 million in fees for the issuance of the May 2017 Amendments. In connection with the March 2017 Amendments and the May 2017 Amendments, we determined that $0.9 million and $1.1 million of deferred costs previously capitalized should be expensed during our second and third fiscal quarters, respectively, as a loss on extinguishment of debt related to syndicated lenders whose debt was extinguished. As of June 30, 2017 , approximately $14.3 million of deferred financing costs remain unamortized, of which $13.0 million is related to the Term Loans and is recorded as a direct reduction of the recognized debt liabilities in our accompanying consolidated balance sheet, and $1.3 million is related to the Revolving Facility and is recorded in other assets in our accompanying consolidated balance sheet.

The Term Loans are secured by a first priority lien on substantially all of our assets and provide that we must comply with certain financial and non-financial covenants. As of June 30, 2017 , we had $688.5 million of outstanding Term Loan borrowings under the Credit Agreement and $160.0 million of borrowing capacity under our Revolving Facility.

As of June 30, 2017 , the following remained outstanding on the Term Loans (in thousands):



Principal balance	$	688,462
Unamortized discount	(6,075		)
Total term loans	$	682,387
Current portion	7,071
Long-term, less current portion	$	675,316

As of June 30, 2017 , the minimum principal payments under the Term Loans in future fiscal years were as follows (in thousands):



2017 (rest of fiscal year)	$	1,768
2018	7,071
2019	7,071
2020	7,071
2021	7,071
Thereafter	658,410
Total	$	688,462

The fair value of the Term Loans was estimated to be approximately $697.9 million as of June 30, 2017 and was determined using Level 2 inputs, including a quoted rate from a bank.

9. CAPITAL LEASE AND FINANCING OBLIGATIONS

Corporate Facility Financing Obligation

On May 26, 2016, we entered into a Purchase and Sale Agreement (“Purchase Agreement”) with Calare Properties, Inc., a Delaware corporation (together with its affiliates, the “Buyer”) for the sale and subsequent leaseback of our corporate headquarters, located at 100 Chelmsford Street, Lowell, Massachusetts. The transactions contemplated by the Purchase Agreement closed on December 28, 2016, at which time we also entered into three lease agreements with the Buyer including: (1) a 20 -year leaseback of the facility located at 100 Chelmsford Street (the “100 Chelmsford Lease”), (2) a 20 -year build-to-suit lease arrangement for the construction and subsequent lease back of a new facility to be located at 144 Chelmsford Street (the “144 Chelmsford Lease”), and (3) a 14 -year building lease renewal of an adjacent facility at 121 Hale Street (the “121 Hale Lease”, and together with the 100 Chelmsford Lease and the 144 Chelmsford Lease, the “Leases”).

Because the transactions contemplated by the Purchase Agreement and the related Leases were negotiated and consummated at the same time and in contemplation of one another to achieve the same commercial objective, the transactions are accounted for by us as a single unit of accounting. In addition, the Leases were determined to represent a failed sale-leaseback due to our continuing involvement in the properties in the form of non-recourse financing. As a result, the Leases are accounted for under the financing method and we will be the deemed accounting owner under the arrangement, including the assets to be constructed under the 144 Chelmsford Lease. We will continue to recognize the existing building and improvements sold under the Purchase Agreement, capitalize the 121 Hale Street building as well as the assets constructed under the Leases, and depreciate the assets over the shorter of their estimated useful lives or the lease terms. The sale proceeds from the Purchase Agreement of $8.2 million (which includes $4.2 million in cash and $4.0 million in construction allowances) and the fair value of the 121 Hale Street building of $4.0 million were recognized as a financing obligation on our balance sheet and are being amortized over the 20 -year lease term based on the minimum lease payments required under the Leases and our incremental borrowing rate. Future construction costs funded by the Buyer under the 144 Chelmsford Lease will be recognized as additional financing obligations on our balance sheet as incurred, and will be amortized over the 20 -year lease term based on the minimum lease payments required under the Leases and our incremental borrowing rate.

As a result of the failed sale-leaseback accounting, we calculated a financing obligation as of the December 28, 2016 inception of the lease based on the future minimum lease payments discounted at 8.5% . The discount rate represents the estimated incremental borrowing rate over the lease term of 20 -years. The minimum lease payments are recorded as interest expense and in part as a payment of principal reducing the financing obligation. The real property assets in the transaction remain on the consolidated balance sheets and continue to be depreciated over the remaining useful lives. As of June 30, 2017 , approximately $13.5 million of the financing obligation was outstanding associated with the Leases.

Acquired Capital Leases

In connection with the FiBest Acquisition in December 2015 and the acquisition of BinOptics Corporation (“BinOptics Acquisition”) in December 2014 we assumed certain capital lease obligations, of which approximately $2.5 million was outstanding as of June 30, 2017 .

As of June 30, 2017 , future minimum payments under capital lease obligations and financing obligations related to the Leases were as follows (in thousands):



Fiscal year ending:	Amount
2017	$	549
2018	1,897
2019	1,793
2020	1,620
2021	1,486
Thereafter	20,541
Total minimum capital lease obligation payments	$	27,886

As of June 30, 2017 , our estimated amortization of our intangible assets in future fiscal years was as follows (in thousands):



	2017 Remaining		2018	2019	2020	2021	Thereafter	Total
Amortization expense	$	19,312	80,837	86,097	82,870	74,338	264,516	$	607,970

Our trade name is an indefinite-lived intangible asset. During development, in-process research and development (“IPR&D”) is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value to its carrying amount. If the carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Once an IPR&D project is complete, it becomes a definite long-lived intangible asset and is evaluated for impairment in accordance with our policy for long-lived assets.

Accumulated amortization for acquired technology and customer relationships were $98.2 million and $72.8 million , respectively, as of June 30, 2017 , and $76.7 million and $48.1 million , respectively, as of September 30, 2016 .

11. STOCKHOLDERS' EQUITY

We have authorized 10 million shares of $0.001 par value preferred stock and 300 million shares of $0.001 par value common stock as of June 30, 2017 and September 30, 2016 . The outstanding shares of our common stock as of June 30, 2017 and September 30, 2016 , presented in the accompanying consolidated statements of stockholders’ equity exclude 200 and 3,300 unvested shares of restricted stock awards, respectively, issued as compensation to employees and directors that remained subject to forfeiture.

Common Stock Warrants —In March 2012, we issued warrants to purchase 1,281,358 shares of common stock for $14.05 per share. The warrants expire December 21, 2020 , or earlier as per the terms of the agreement, including immediately following consummation of a sale of all or substantially all assets or capital stock or other equity securities, including by merger, consolidation, recapitalization, or similar transactions. We do not currently have sufficient registered and available shares to immediately satisfy a request for registration, if such a request were made. As of June 30, 2017 , no exercise of the warrants had occurred and no request had been made to register the warrants or any underlying securities for resale by the holders.

We are recording the estimated fair values of the warrants as a long-term liability in the accompanying consolidated financial statements with changes in the estimated fair value being recorded in the accompanying statements of operations. See

Note 5 - Fair Value for additional information related to the fair value of our warrant liability.

12. EARNINGS (LOSS) PER SHARE

The following table sets forth the computation for basic and diluted net loss per share of common stock (in thousands, except per share data):

13. COMMITMENTS AND CONTINGENCIES

From time to time we may be subject to commercial disputes, employment issues, claims by other companies in the industry that we have infringed their intellectual property rights and other similar claims and litigations. Any such claims may lead to future litigation and material damages and defense costs. Other than as set forth below, we were not involved in any material pending legal proceedings during the fiscal quarter ended June 30, 2017 .

GaN Lawsuit Against Infineon. On April 26, 2016, we and our wholly-owned subsidiary Nitronex, LLC brought suit against Infineon Technologies Americas Corporation (“Infineon Americas”) and Infineon Technologies AG (“Infineon AG” and collectively, with Infineon Americas, “Infineon”) in the Federal District Court for the Central District of California, seeking injunctive relief, monetary damages, and specific performance of certain contractual obligations. On July 19, 2016, we filed a first amended complaint, and, on November 21, 2016, we filed a second amended complaint. After motions to dismiss certain claims from MACOM’s second amended complaint were denied on February 28, 2017, Infineon AG answered on March 24, 2017, asserting no counterclaims. Infineon Americas also answered and counterclaimed on March 24, 2017 and then submitted amended counterclaims on April 14, 2017. The District Court dismissed one of the counterclaims on June 5, 2017, and Infineon filed further amended counterclaims on June 19, 2017. We have moved to strike Infineon’s affirmative defenses of patent

invalidity. Additionally, on July 24, 2017, we moved for a finding of civil contempt and sanctions based on Infineon Americas’ violations of the preliminary injunction in effect in the case.

The suit arises out of agreements relating to GaN patents that were executed in 2010 by Nitronex Corporation (acquired by us in 2014) and International Rectifier Corporation (“International Rectifier”) (acquired by Infineon AG in 2015). We assert claims for breach of contract, breach of the covenant of good faith and fair dealing, declaratory judgment of contractual rights, declaratory judgment of non-infringement of patents, and, against Infineon AG only, intentional interference with contract. If successful, the relief sought in our second amended complaint would, among other remedies, require Infineon to assign back to us certain GaN-related Nitronex patents that were previously assigned to International Rectifier and enjoin Infineon from proceeding with its marketing and sales of certain types of GaN-on-Si products. In an order dated October 31, 2016, the District Court granted us a preliminary injunction against Infineon, which then issued on December 8, 2016 and was modified on March 6, 2017. The preliminary injunction declares that an exclusive licensing arrangement between us and Infineon that Infineon had purported to terminate is still in effect and prohibits Infineon Americas and others acting in concert with it from engaging in certain activities in our exclusive field, which includes RF power amplifiers for cellular base stations. Infineon appealed the preliminary injunction order to the Federal Circuit on January 3, 2017, and we appealed the modification order on April 5, 2017. The appeals are now fully briefed, and the Federal Circuit has ordered that they will be heard together. Meanwhile, the District Court case is proceeding, although no date has yet been set for trial.

With respect to the above legal proceeding, we are not able to reasonably estimate the amount or range of any possible loss, and accordingly have not accrued or disclosed any related amounts of possible loss in the accompanying consolidated financial statements.

14. RESTRUCTURINGS

We have periodically implemented restructuring actions in connection with broader plans to reduce staffing, reduce our internal manufacturing footprint and, generally, reduce operating costs. The restructuring expenses are primarily comprised of direct and incremental costs related to headcount reductions including severance and outplacement fees for the terminated employees, as well as facility closure costs.

The following is a summary of the costs incurred and remaining balances included in accrued expenses for the nine months ended June 30, 2017 (in thousands):



Balance as of September 30, 2016	$	3,104
Acquired liability	93
Current period expense	2,342
Payments	(5,086		)
Balance as of June 30, 2017	$	453

The restructuring expenses recorded to date are expected to be paid through the remainder of fiscal year 2017 . Our restructuring charges incurred to date are primarily employee related with non-employee related charges determined to be immaterial. We expect to incur additional restructuring costs of approximately $0.3 million to $1.3 million during the remainder of calendar year 2017 as we complete restructuring actions primarily associated with facility consolidations.

15. SHARE-BASED COMPENSATION

Stock Plans

As of June 30, 2017 , we had 13.0 million shares available for future issuance under our 2012 Omnibus Incentive Plan (as Amended and Restated) (the “2012 Plan”), and 3.0 million shares available for issuance under our Employee Stock Purchase Plan (“ESPP”). Under the 2012 Plan, we have the ability to issue incentive stock options (“ISOs”), non-statutory stock options (“NSOs”), performance based non-statutory stock options, stock appreciation rights, restricted stock (“RSAs”), restricted stock units (“RSUs”), performance-based stock units (“PRSUs”), performance shares and other equity-based awards to employees, directors and outside consultants. The ISOs and NSOs must be granted at a price per share not less than the fair value of our common stock on the date of grant. Options granted to date primarily vest based on certain market-based and performance-based criteria as described below. Options granted generally have a term of seven to ten years. Certain of the share-based awards granted and outstanding as of June 30, 2017 are subject to accelerated vesting upon a change in control. There were no modifications to share-based awards during the periods presented. As of June 30, 2017 , total unrecognized compensation cost related to the employee stock purchase plan was not material.

Share-Based Compensation

The following table shows a summary of share-based compensation expense included in the Condensed Consolidated Statements of Operations for the three and nine months ended June 30, 2017 and July 1, 2016 (in thousands):



	Three Months Ended				Nine Months Ended
	June 30, 2017		July 1, 2016		June 30, 2017		July 1, 2016
Cost of revenue	$	846	$	652	$	2,245	$	1,602
Research and development	3,006		1,903		7,677		5,411
Selling, general and administrative	6,083		3,626		17,744		12,394
Total share-based compensation expense (1)	$	9,935	$	6,181	$	27,666	$	19,407

(1) Includes $0.3 million and $0.6 million related to discontinued operations for the three and nine months ended June 30, 2017 , respectively.

As of June 30, 2017 , the total unrecognized compensation costs, adjusted for estimated forfeitures, related to outstanding stock options, restricted stock awards and units including awards with time-based and performance based vesting was $71.2 million , which we expect to recognize over a weighted-average period of 2.6 years.

Stock Options

We had 1.2 million stock options outstanding as of June 30, 2017 , with a weighted-average exercise price per share of $31.30 and weighted-average remaining contractual term of 5.2 years . The aggregate intrinsic value of the stock options outstanding as of June 30, 2017 was $29.8 million which represents our closing stock price value on the last trading day of the period in excess of the weighted-average exercise price multiplied by the number of options outstanding.

During November 2016, we granted 310,000 non-qualified stock options with a grant date fair value of $4.1 million that are subject to vesting only upon the market price of the Company’s underlying public stock closing above a certain price target within seven years of the date of grant. These non-qualified stock options with market related vesting conditions are valued using a Monte Carlo simulation model, using a volatility rate of 32.2% , a risk-free rate of 1.84% , a strike price of $40.25 and a term of seven years . Share-based compensation expense is recognized regardless of the number of awards that are earned based on the market condition and is recognized on a straight-line basis over the estimated service period of approximately three years . If the required service period is not met for these options then the share-based compensation expense would be reversed. In the event that the Company’s common stock achieves the target price of $66.96 per share based on a 30 day trailing average prior to the end of the estimated service period, any remaining unamortized compensation cost will be recognized.

During January 2017, we granted 10,000 non-qualified stock options with a grant date fair value of $0.2 million that are subject to vesting only upon the market price of the Company’s underlying public stock closing above a certain price target within seven years of the date of grant. These non-qualified stock options with market related vesting conditions are valued using a Monte Carlo simulation model, using a volatility rate of 34.5% , a risk-free rate of 2.25% , a strike price of $46.28 and a term of seven years . Share-based compensation expense is recognized regardless of the number of awards that are earned based on the market condition and is recognized on a straight-line basis over the estimated service period of approximately three years . If the required service period is not met for these options then the share-based compensation expense would be reversed. In the event that the Company’s common stock achieves the target price of $80.70 per share based on a 30 day trailing average prior to the end of the estimated service period, any remaining unamortized compensation cost will be recognized.

The total intrinsic value of options exercised was $6.3 million and $8.2 million for the three and nine months ended June 30, 2017 , respectively, and was $0.8 million and $2.7 million for the three and nine months ended July 1, 2016 , respectively.

Restricted Stock, Restricted Stock Units and Performance-Based Restricted Stock Units

A summary of restricted stock, restricted stock unit and performance-based restricted stock unit activity for the nine months ended June 30, 2017 , is as follows:



	Number of RSUs		Weighted- Average Grate Date Fair Value		Aggregate Intrinsic Value (in thousands)
Balance at September 30, 2016	1,707,695		$	32.76	$	72,165
Granted	1,244,563		37.77
Vested and released	(955,522	)	26.62
Forfeited, canceled or expired	(70,247	)	36.81
Balance at June 30, 2017	1,926,489		$	38.89	$	107,431

Restricted stock, restricted stock units and performance-based restricted stock units that vested during the nine months ended June 30, 2017 and July 1, 2016 had fair value of $46.8 million and $26.4 million as of the vesting date, respectively.

16. INCOME TAXES

We are subject to income tax in the U.S. as well as other tax jurisdictions in which we conduct business. Earnings from non-U.S. activities are subject to local country income tax and may also be subject to current U.S. income tax. For interim periods, we record a tax provision or benefit based upon the estimated effective tax rate expected for the full fiscal year, adjusted for material discrete taxation matters arising during the interim periods.

The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rates for the three and nine months ended July 1, 2016 , was primarily impacted by changes in fair values of the common stock warrant liability which is neither deductible nor taxable for tax purposes, income taxed in foreign jurisdictions at generally lower tax rates, non-deductible compensation, research and development tax credits and non-deductible merger expenses, offset by U.S. state income taxes. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rates for the three and nine months ended June 30, 2017 was primarily driven by the establishment of a full valuation allowance against our U.S. deferred tax assets during the fiscal quarter ended March 31, 2017 and changes to the valuation allowance during the fiscal quarter ended June 30, 2017 .

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making this determination, we consider available positive and negative evidence and factors that may impact the valuation of our deferred tax asset including results of recent operations, future reversals of existing taxable temporary differences, projected future taxable income, and tax-planning strategies. A significant piece of objective negative evidence evaluated was the cumulative U.S. loss incurred over the three-year period ended March 31, 2017 which we believe limited our ability to consider other subjective evidence, such as our projections for future growth. Certain transaction and integration related expenses incurred in the U.S. primarily associated with the AppliedMicro Acquisition during the three months ended March 31, 2017 resulted for the first time in significant negative objective evidence in the form of adjusted cumulative losses in the U.S. over the past three-year period. This resulted in our determination during the fiscal quarter ended March 31, 2017 that there was not sufficient objectively verifiable positive evidence to offset this negative objective evidence and we concluded that a full valuation allowance was required for our U.S. deferred tax assets, totaling $89.7 million as of June 30, 2017 . In addition, a full valuation allowance was established against the U.S. deferred tax assets acquired in connection with the AppliedMicro Acquisition.

The balance of the unrecognized tax benefit as of June 30, 2017 and September 30, 2016 did not change and remained at $1.7 million . The unrecognized tax benefits primarily relate to positions taken by us in our 2014 U.S. tax filings. The entire balance of unrecognized tax benefits, if recognized, will reduce income tax expense. It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal quarters ended June 30, 2017 and September 30, 2016 , we did not make any accrual or payment of interest and penalties due to our U.S. net operating loss carryover position.

As disclosed in

Note 2 - Acquisiti ons, our purchase accounting for the AppliedMicro Acquisition, including income taxes, is preliminary and subject to revision upon obtaining and analyzing all information.

Our purchase accounting related to the FiBest Acquisition, including income taxes, was finalized during the three months ended December 30, 2016. We recorded an aggregate net deferred income tax liability estimated to be $11.6 million which includes a net deferred income tax asset of $2.5 million relating to net operating loss ("NOL") carryforwards and a net deferred income tax liability of $14.1 million related to the difference between the book and tax basis of the intangible and other assets acquired. Related to the Metelics Acquisition we do not anticipate the recording of any deferred taxes due to a Section 338(h) (10) election which will permit us to have tax basis equal to the purchase price.

17. RELATED PARTY TRANSACTIONS

GaAs Labs, LLC (“GaAs Labs”), a former stockholder and an affiliate of directors John and Susan Ocampo, continues to engage us to provide administrative and business development services to GaAs Labs on a time and materials basis. There are no minimum service requirements or payment obligations and the agreement may be terminated by either party with 30 days notice. In the nine months ended June 30, 2017 and July 1, 2016 , we recorded no material billings to GaAs Labs.

Overview

We are a leading provider of high-performance analog semiconductor solutions that enable next-generation Internet applications, the cloud connected apps economy, and the modern, networked battlefield across the radio frequency (“RF”), microwave, millimeterwave and lightwave spectrum. We design and manufacture differentiated, high-value products for customers who demand high performance, quality, and reliability. We offer a broad portfolio of over 4,500 standard and custom devices, which include lasers, PAM-4 PHYs, modulator drivers, transimpedance amplifiers ("TIA"), integrated circuits (“IC”), multi-chip modules, power pallets and transistors, diodes, amplifiers, switches and switch limiters, passive and active components and complete subsystems, across approximately 40 product lines serving over 6,500 end customers in three primary markets. Our products are electronic and optical components that our customers incorporate into their larger electronic systems, such as, Cloud Data Centers, point-to-point wireless backhaul radios, high density networks, active antenna arrays, radar, magnetic resonance imaging systems (“MRI”) and unmanned aerial vehicles (“UAVs”). Our primary markets are: Networks, which includes photonic solutions and fiber optic applications, MACsec, carrier and enterprise infrastructure, wired broadband and cellular backhaul, and cellular infrastructure; Aerospace and Defense (“A&D”), which includes military and commercial radar, RF jammers, electronic countermeasures, and communication data links; and Multi-market, which includes industrial, medical, test and measurement and scientific applications.

Description of Our Revenue

Revenue. Substantially all of our revenue is derived from sales of high-performance RF, microwave, millimeterwave and lightwave semiconductor solutions. We design, integrate, manufacture and package differentiated product solutions that we sell to customers through our direct sales organization, our network of independent sales representatives and our distributors.

We believe the primary drivers of our future revenue growth will include:


•	engaging early with our lead customers to develop products and solutions that can be driven across multiple growth markets;


•	leveraging our core strength and leadership position in standard, catalog products that service all of our end applications;


•	increasing content of our semiconductor solutions in our customers’ systems through cross-selling of our more than 40 product lines;


•	introducing new products through internal development and acquisitions with market reception that command higher prices based on the application of advanced technologies such as GaN, added features, higher levels of integration and improved performance; and


•	continued growth in the market for high-performance analog and optical semiconductors in our three primary markets in particular.

Our core strategy is to develop and innovate high-performance products that address our customers’ most difficult technical challenges in our primary markets: Networks, A&D and Multi-market. While sales in any or all of our primary markets may slow or decline from period to period, over the long-term we generally expect to benefit from strength in these markets.

We expect our revenue in the Networks market to be primarily driven by continued upgrades and expansion of communications equipment to support the proliferation of mobile computing devices such as smartphones and tablets, increasing adoption of bandwidth rich services such as video on demand and cloud computing, the rapid adoption of cloud-based services and the migration to an application centric architecture, which we expect will drive adoption of higher speed, low latency optical and wireless links.

We expect our revenue in the A&D market to be driven by the upgrading of radar systems and modern battlefield communications equipment and networks designed to improve situational awareness. Growth in this market is subject to changes in governmental programs and budget funding, which is difficult to predict.

We expect revenue in Multi-market to be driven by diverse demand for our multi-purpose catalog products.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements. The preparation of financial statements, in conformity with generally accepted accounting principles in the U.S. (“GAAP”), requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and could be material if our actual or expected experience were to change unexpectedly. On an ongoing basis, we re-evaluate our estimates and judgments.

We base our estimates and judgments on our historical experience and on other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates and material effects on our operating results and financial position may result. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; goodwill and intangibles asset valuations and associated impairment assessments; revenue reserves; deferred tax valuation allowances; contingent consideration valuations and share-based compensation valuations.

For additional information related to these and other accounting policies refer to

Comparison of the Three and Nine Months Ended June 30, 2017 to the Three and Nine Months Ended July 1, 2016

We acquired AppliedMicro on January 26, 2017. For additional information related to the AppliedMicro Acquisition refer to Note 2 - Acquisitions and

Note 3 - Discontinued Operations in this Quarterly Report on Form 10-Q. Our quarterly Statements of Operations includes activity since the date of acquisition, representing less than six months of activity for AppliedMicro for the three and nine months ended June 30, 2017 .

We acquired FiBest and Metelics during December 2015. For additional information related to the FiBest Acquisition and Metelics Acquisition refer to

Note 2 - Acquisitions . Our quarterly Statements of Operations includes activity since the dates of acquisition, representing less than nine months of activity for FiBest and Metelics for the three and nine months ended July 1, 2016 .

Revenue. Our revenue increased $52.3 million , or 36.7% , to $194.6 million for the three months ended June 30, 2017 , from $142.3 million for the three months ended July 1, 2016 , and our revenue increased $140.8 million , or 35.9% , to $532.4 million for the nine months ended June 30, 2017 , from $391.6 million for the nine months ended July 1, 2016 . The increase in revenue in the three and nine months ended June 30, 2017 is further described by end market in the following paragraphs.

Revenue from our primary markets, the percentage of change between the periods presented, and revenue by primary markets expressed as a percentage of total revenue in the periods presented were (in thousands, except percentages):



		Three Months Ended								Nine Months Ended
		June 30, 2017			July 1, 2016		% Change			June 30, 2017			July 1, 2016		% Change
Networks	$	150,130		$	104,605		43.5	%	$	399,416		$	283,969		40.7	%
A&D		21,439			18,128		18.3	%		65,700			54,466		20.6	%
Multi-market		22,986			19,555		17.5	%		67,275			53,206		26.4	%
Total	$	194,555		$	142,288		36.7	%	$	532,391		$	391,641		35.9	%

Networks		77.2	%		73.5	%				75.0	%		72.5	%

Total		100.0	%		100.0	%				100.0	%		100.0	%

In the three and nine months ended June 30, 2017 , our Networks market revenue increased by $45.5 million , or 43.5% , and $115.4 million , or 40.7% , respectively, compared to the three and nine months ended July 1, 2016 . The increase was primarily related to the inclusion of revenue from the AppliedMicro Acquisition, as well as, increased sales of our other products targeting Cloud Data Centers. These increases were partially offset by weakness in our products targeting fiber to the home and carrier-based optical revenue.

In the three and nine months ended June 30, 2017 , our A&D market revenue increased by $3.3 million , or 18.3% , and $11.2 million , or 20.6% , respectively, compared to the three and nine months ended July 1, 2016 . The increase was primarily due to incremental revenue from the inclusion of revenue from the Metelics Acquisition.

In the three and nine months ended June 30, 2017 , our Multi-market revenues increased by $3.4 million , or 17.5% , and $14.1 million , or 26.4% , respectively, compared to the three and nine months ended July 1, 2016 . The increase was primarily due to incremental revenue from the inclusion of revenue from the Metelics Acquisition and certain AppliedMicro products.

Gross profit. Gross margin was 47.6% and 45.1% for the three and nine months ended June 30, 2017 , respectively, and 52.0% and 51.0% for the three and nine months ended July 1, 2016 , respectively. Gross profit during the three and nine months ended June 30, 2017 , was negatively impacted by higher intangibles amortization and amortization of inventory step-up associated with the AppliedMicro Acquisition during the fiscal 2017 periods, partially offset by increased profit associated with revenue from recently acquired businesses and lower compensation expense and impairment related charges associated with a product line exit incurred during the three months ended April 1, 2016.

Research and development. R&D expense increased by $12.7 million , or 48.6% , to $38.7 million , or 19.9% of our revenue, for the three months ended June 30, 2017 , compared with $26.1 million , or 18.3% of our revenue, for the three months ended July 1, 2016 . R&D expense increased by $31.0 million , or 40.0% , to $108.6 million , or 20.4% of our revenue, for the nine months ended June 30, 2017 , compared with $77.6 million , or 19.8% of our revenue, for the nine months ended July 1, 2016 . R&D expense has increased in the fiscal 2017 periods primarily as a result of additional costs from our acquisitions, higher depreciation expense, share-based compensation and increased spending on new product development initiatives.

Selling, general and administrative. Selling, general and administrative expense increased by $10.8 million , or 30.1% , to $46.7 million , or 24.0% of our revenue, for the three months ended June 30, 2017 , compared with $35.9 million , or 25.2% of our revenue, for the three months ended July 1, 2016 . Selling, general and administrative expense increased by $40.3 million , or 38.3% , to $145.5 million , or 27.3% of our revenue, for the nine months ended June 30, 2017 , compared with $105.2 million , or 26.9% of our revenue, for the nine months ended July 1, 2016 . Selling, general and administrative expenses increased in the fiscal 2017 periods primarily due to $12.0 million of change in control compensation expense, and $11.0 million of transaction related expenses associated with the AppliedMicro Acquisition. In addition, we incurred higher intangible amortization and share-based compensation as well as additional acquisition integration related costs, partially offset by lower acquisition related compensation expenses and variable compensation expense.

Impairment charges. We did not incur any Impairment charges for the three and nine months ended June 30, 2017 . During the three and nine months ended July 1, 2016 we incurred $0.8 million and $11.8 million, respectively, of impairment related charges associated with the exit of a product line.

Restructuring charges. Restructuring charges totaled $0.6 million and $1.1 million for the three months ended June 30, 2017 and July 1, 2016 and $2.3 million and $2.1 million for the nine months ended June 30, 2017 and July 1, 2016 , respectively. The increase in restructuring charges during the first nine months of fiscal year 2017 was primarily related to the Metelics Acquisition

as well as our planned exit of a facility in California. We expect to incur additional restructuring costs of approximately $0.3 million to $1.3 million during the remainder of calendar year 2017 as we complete these and other restructuring actions.

Warrant liability . Our warrant liability resulted in an expense of $9.1 million and $16.5 million for the three and nine months ended June 30, 2017 , respectively, compared to a gain of $15.3 million and loss of $3.7 million for the three and nine months ended July 1, 2016 , respectively. The differences between periods were primarily driven by changes in the estimated fair value of common stock warrants we issued in December 2010, which we carry as a liability at fair value.

Provision for income taxes. Income tax expense was $3.2 million for the three months ended June 30, 2017 , compared to a benefit of $0.2 million for the three months ended July 1, 2016 . Income tax expense was $93.6 million for the nine months ended June 30, 2017 , compared to a benefit of $6.2 million for the nine months ended July 1, 2016 . The income tax expense for the three and nine months ended June 30, 2017 resulted primarily from the establishment of a full valuation allowance against our U.S. deferred tax assets during the fiscal quarter ended March 31, 2017 and changes to the valuation allowance during the fiscal quarter ended June 30, 2017. The income tax expense for the three and nine months ended July 1, 2016 was impacted by a discrete expense of $4.2 million and $19.1 million, respectively, for changes in the fair value of our common stock warrant liability and a discrete write-off of $11.0 million for assets associated with exiting a product line.

The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rate for the three and nine months ended July 1, 2016 , was primarily impacted in all periods by changes in fair values of the common stock warrant liability which is neither deductible nor taxable for tax purposes, income taxed in foreign jurisdictions at generally lower tax rates, non-deductible compensation, research and development tax credits and non-deductible merger expenses, offset by U.S. state income taxes. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rates for the three and nine months ended June 30, 2017 , was primarily driven by the establishment of a full valuation allowance against our U.S. deferred tax assets during the fiscal quarter ended March 31, 2017 and changes to the valuation allowance during the fiscal quarter ended June 30, 2017.

Liquidity and Capital Resources

The following table summarizes our cash flow activities for the nine months ended June 30, 2017 and July 1, 2016 , respectively (in thousands):



	June 30, 2017			July 1, 2016
Cash and cash equivalents, beginning of period	$	332,977		$	122,312
Net cash provided by operating activities	48,689			54,347
Net cash used in investing activities	(290,436		)	(91,231		)

Foreign currency effect on cash	(175		)	(583		)
Cash and cash equivalents, end of period	$	167,606		$	66,842

Cash Flow from Operating Activities:

Our cash flow from operating activities for the nine months ended June 30, 2017 of $48.7 million consisted of a net loss of $158.8 million , plus adjustments to reconcile our net loss to cash provided by operating activities of $229.6 million less changes in operating assets and liabilities of $22.1 million . Adjustments to reconcile our net loss to cash provided by operating activities of $229.6 million primarily included $87.6 million of deferred tax adjustments, depreciation and intangible amortization expense of $65.8 million , $44.0 million of amortization of the step-up of acquired inventory, share-based incentive compensation expense of $27.7 million and warrant liability expense of $16.5 million , partially offset by income from discontinued operations of $23.6 million . In addition, cash used by operating assets and liabilities was $22.1 million for the nine months ended June 30, 2017 , primarily driven by an increase in accounts receivable of $12.8 million and decreases in accrued and other liabilities of $17.8 million , partially offset by decreases in inventory of $8.0 million .

Our cash flow from operating activities for the nine months ended July 1, 2016 of $54.3 million consisted of a net loss of $3.7 million plus adjustments to reconcile our net loss to cash provided by operating activities of $91.3 million less changes in operating assets and liabilities of $33.3 million . Adjustments to reconcile our net loss to cash provided by operating activities of $91.3 million primarily included depreciation and intangible amortization expense of $52.6 million , share-based incentive compensation expense of $19.4 million , impairment charges of $13.0 million and warrant liability expense of $3.7 million . In addition, cash used by operating assets and liabilities was $33.3 million for the nine months ended July 1, 2016 , primarily driven by an increase in inventory of $25.1 million and a decrease in accounts payable of $2.2 million .

Cash Flow from Investing Activities:

Our cash flow used by investing activities for the nine months ended June 30, 2017 consisted primarily of $231.7 million of net cash for the AppliedMicro Acquisition, purchases of $90.5 million of short term investments and capital expenditures of $24.5 million , partially offset by proceeds of $32.4 million related to the sale of short term investments and $23.6 million associated with the Automotive Business discontinued operations including $18.0 million of indemnification escrow and $5.6 million related to a consulting agreement.

Our cash flow used by investing activities for the nine months ended July 1, 2016 consisted primarily of cash paid for the FiBest and Metelics acquisitions of $85.5 million and capital expenditures of $24.1 million . The $3.8 million of cash provided from discontinued operations during the nine months ended July 1, 2016 was associated with the Automotive Business consulting agreement. Additionally, during the nine months ended July 1, 2016 , we purchased $24.9 million of short term investments and received proceeds of $40.4 million related to the sale of short term investments which was used to fund acquisitions and operating activities.

Cash Flow from Financing Activities:

During the nine months ended June 30, 2017 , our cash provided by financing activities of $76.6 million was primarily related to $96.6 million of proceeds from notes payable, $8.2 million of proceeds from stock option exercises and employee stock purchases and $4.3 million of proceeds from the sale of our corporate headquarters facility, partially offset by $18.1 million in purchases of stock associated with employee tax withholdings, $9.1 million of financing costs paid and $3.0 million of payments on notes payable.

During the nine months ended July 1, 2016 , our cash used in financing activities of $18.0 million consisted primarily of $9.6 million in payments on debt assumed as part of our FiBest Acquisition, and $10.0 million in purchases of stock associated with employee tax withholdings, partially offset by proceeds from stock option exercises and employee stock purchases of $5.3 million .

Liquidity

As of June 30, 2017 , we held $167.6 million of cash and cash equivalents, primarily deposited with financial institutions. The undistributed earnings of our foreign subsidiaries are indefinitely reinvested and we do not intend to repatriate such earnings. We believe the decision to reinvest these earnings will not have a significant impact on our liquidity. As of June 30, 2017 , cash held by our foreign subsidiaries was $62.6 million , which, along with cash generated from foreign operations, is expected to be used in the support of international growth and working capital requirements as well as the repayment of certain intercompany loans. As of June 30, 2017 , we also held $81.6 million of liquid short-term investments, and had $160.0 million in borrowing capacity under our revolving credit facility.

We plan to use our remaining available cash and cash equivalents, short term investments, and as deemed appropriate our borrowing capacity under our revolving credit facility for general corporate purposes, including working capital, or for the acquisition of or investment in complementary technologies, design teams, products and businesses. We believe that our cash and cash equivalents, short term investments, cash generated from operations, and borrowing availability under our revolving credit facility will be sufficient to meet our working capital requirements for at least the next 12 months. We may need to raise additional capital from time to time through the issuance and sale of equity or debt securities, and there is no assurance that we will be able do so on favorable terms or at all.

For additional information related to our Liquidity and Debt, see

Note 8 - Debt to our Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Recent Accounting Pronouncements

Our Recent Accounting Pronouncements are described in the notes to our September 30, 2016 consolidated financial statements, which were included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016 .

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments , which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Acquirers will now recognize measurement-period adjustments during the period in which they determine the amount of the adjustment. This ASU is effective for annual and interim reporting periods beginning after December 15, 2015, and should be applied prospectively to adjustments for provisional amounts that occur after the effective date. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of June 30, 2017 .

Contractual Obligations

In connection with the AppliedMicro Acquisition in January 2017, we assumed operating lease obligations of approximately $2.2 million, of which approximately $1.6 million remain outstanding as of June 30, 2017 . There have been no other material changes in our contractual obligations as of June 30, 2017 , compared to those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016 filed with the SEC on November 17, 2016.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the ordinary course of business, which consists primarily of interest rate risk associated with our cash and cash equivalents, short-term investments and our variable rate debt, as well as foreign exchange rate risk. In addition, the value of our warrant liability is based on the underlying price of our common stock and changes in its value could significantly impact our warrant liability expense.

Interest rate risk. The primary objectives of our investment activity are to preserve principal, provide liquidity and invest excess cash for an average rate of return. To minimize market risk, we maintain our portfolio in cash and diversified investments, which may consist of corporate and agency bonds, bank deposits, money market funds and commercial paper. Certain interest rates are variable and fluctuate with current market conditions. The risk associated with fluctuating interest rates is limited to this investment portfolio. We believe that a 10% change in interest rates would not have a material impact on our financial position or results of operations. We do not enter into financial instruments for trading or speculative purposes.

Our exposure to interest rate risk also relates to the increase or decrease in the amount of interest expense we must pay on the outstanding debt under the Credit Agreement. The interest rates on our term loans and revolving credit facility are variable interest rates based on our lender’s prime rate or a LIBOR rate, in each case plus an applicable margin, which exposes us to market interest rate risk when we have outstanding borrowings under the Credit Agreement. As of June 30, 2017 , we had $688.5 million of outstanding borrowings under the Credit Agreement. Assuming our outstanding debt remains constant under the Credit Agreement for an entire year and the applicable annual interest rate increases or decreases by 1%, our annual interest expense would increase or decrease by $7.0 million .

Foreign currency risk. To date, our international customer agreements have been denominated primarily in U.S. dollars. Accordingly, we have limited exposure to foreign currency exchange rates. The foreign operations we acquired in the FiBest acquisition have transactions which are predominately denominated in Japanese Yen. The functional currency of a majority of our foreign operations continues to be in U.S. dollars with the remaining operations being local currency. Increases in the value of the U.S. dollar relative to other currencies could make our products more expensive, which could negatively impact demand in certain regions. Conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our products being more expensive to certain customers and could reduce or delay orders, or otherwise negatively affect how they do business with us. The effects of exchange rate fluctuations on the net assets of the majority of our operations are accounted for as transaction gains or losses. We believe that a change of 10% in such foreign currency exchange rates would not have a material impact on our financial position or results of operations. In the future, we may enter into foreign currency exchange hedging contracts to reduce our exposure to changes in exchange rates.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) were effective as of June 30, 2017 .

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

GaN Lawsuit Against Infineon . On April 26, 2016, we and our wholly-owned subsidiary Nitronex, LLC brought suit against Infineon Technologies Americas Corporation (“Infineon Americas”) and Infineon Technologies AG (“Infineon AG” and collectively, with Infineon Americas, “Infineon”) in the Federal District Court for the Central District of California, seeking injunctive relief, monetary damages, and specific performance of certain contractual obligations. On July 19, 2016, we filed a first amended complaint, and, on November 21, 2016, we filed a second amended complaint. After motions to dismiss certain claims from MACOM’s second amended complaint were denied on February 28, 2017, Infineon AG answered on March 24, 2017, asserting no counterclaims. Infineon Americas also answered and counterclaimed on March 24, 2017 and then submitted amended counterclaims on April 14, 2017. The District Court dismissed one of the counterclaims on June 5, 2017, and Infineon filed further amended counterclaims on June 19, 2017. We have moved to strike Infineon’s affirmative defenses of patent invalidity. Additionally, on July 24, 2017, we moved for a finding of civil contempt and sanctions based on Infineon Americas’ violations of the preliminary injunction in effect in the case.

ITEM 1A. RISK FACTORS

Our business involves a high degree of risk. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016 , our Quarterly Report on Form 10-Q for the fiscal quarter ended December 30, 2016 and our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2017, which could materially affect our business, financial condition or future results. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes in any of the risk factors described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016 , our Quarterly Report on Form 10-Q for the fiscal quarter ended December 30, 2016 and our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2017 , except as noted below.

If demand for our products in our primary markets declines or fails to grow, our revenue and profitability may suffer.

Our future growth depends on our ability to anticipate demand and respond to that demand with products that address our customers' needs. To a significant extent, this growth depends on the continued growth in usage of advanced electronic systems in our primary markets: Networks, A&D and Multi-market generally, and in the optical networks market in particular, which accounted for 53% of our revenue in the fiscal year ended September 30, 2016. The rate and extent to which these markets will grow, if at all, is uncertain. For example, we anticipate significant growth in the demand for our products in cloud data centers, and have focused significant internal resources to meet that anticipated demand. Our ability to capitalize on this and our other previously announced market opportunities in 100G optical networks, GaN technology and active antennas will depend on, among other things, the future size and growth rates of these markets, the next generation technologies selected by customers, the timing of network upgrades in these markets and the future pace of adoption of our products in these markets. Our markets may fail to grow or decline for many reasons, including macro-economic factors, insufficient consumer demand, technological hurdles, research and development delays, lack of access to capital, sequestration or other changes in the U.S. defense budget and procurement processes and changes in export controls or other regulatory environments. For example, in fiscal 2017 we experienced decreased demand in China for our products targeting 2.5 Gigabit passive optical networks (PON), metro/long-haul optical network

deployments and other carrier-side applications, as carriers began migrating from 2.5 Gigabit to 10 Gigabit PON and the pace of provincial network deployments in China slowed. Even if our primary markets grow, demand for our products in those markets may fail to grow in the event that they fail to embrace next-generation technologies we offer such as GaN-on-Silicon, etched facet lasers and radar tiles, or adopt technologies other than those we offer or implement changes in network specifications that our products do not adequately address. For instance, if demand for our products targeting 10 Gigabit PON deployments is lower or slower to materialize than we anticipate, or we fail to deliver a portfolio of 10 Gigabit PON products that meets the full set of solution requirements our customers demand within the requisite market window, our revenues could fail to grow or decline and our results of operations could be adversely affected. If demand for electronic systems that incorporate our products declines, fails to grow or grows more slowly than we anticipate, purchases of our products may be reduced, which will adversely affect our business, financial condition and results of operations. A failure to predict demand or respond to demand with successful products in timely fashion will materially affect our revenues and profitability.

We are subject to order and shipment uncertainties. Our profitability will decline if we fail to accurately forecast customer demand when managing inventory.

We generally sell our products on the basis of purchase orders rather than long-term purchase commitments from our customers. Our customers can typically cancel purchase orders or defer product shipments for some period without incurring a liability to us. We typically plan production and inventory levels based on internal forecasts of customer demand, which can be highly unpredictable and can fluctuate substantially, leading to excess inventory write-downs and resulting negative impacts on gross margin and net income. We have limited visibility into our customers’ inventories, future customer demand and the product mix that our customers will require, which could adversely affect our production forecasts and operating margins. The difficulty in predicting demand may be compounded when we sell to OEM customers indirectly through distributors or contract manufacturers, or both, as our forecasts of demand are then based on estimates provided by multiple parties. In a number of markets we serve, large dollar value customer orders scheduled for delivery in the current fiscal quarter may be canceled or rescheduled by the customer for delivery in a future fiscal quarter on short notice, which may cause our reported revenue to vary materially from our prior expectations. In addition, the rapid pace of innovation in our industry, such as the reported decrease in 2.5 Gigabit PON spending by carriers in China in fiscal year 2017 in preparation for an eventual transition to 10 Gigabit PON deployments, could render significant portions of our inventory obsolete. If we overestimate our customers’ requirements, we may have excess inventory, which could lead to obsolete inventory and unexpected costs. Further, if we build inventory specific to non-recurring engineering (NRE) arrangements that we may enter into with our customers from time to time and then fail to achieve one or more required milestones in connection with such NRE arrangements, we may have excess, non-qualified or non-conforming customer specific inventory, which could lead to unsellable inventory and unexpected costs. Conversely, if we underestimate our customers’ requirements, we may have inadequate inventory, which could lead to foregone revenue opportunities, loss of potential market share and damage to customer relationships caused by product deliveries not made on a timely basis and disrupting our customers’ production schedules. Some of our larger customers also require us to build and maintain minimum inventories and keep them available for purchase at specified locations based on non-binding demand estimates that are subject to change, which exposes us to increased inventory risk and makes it more difficult to manage our working capital. If demand from such customers decreases, we may be left with excess or obsolete inventory that we are unable to sell. In response to anticipated long lead times to obtain inventory and materials from outside suppliers and foundries, we periodically order materials and build a stock of finished goods inventory in advance of customer demand. This advance ordering of raw material and building of finished goods inventory has in the past and may in the future result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize or other factors make our products less saleable. In addition, any significant future cancellation or deferral of product orders could adversely affect our revenue and margins, increase inventory write-downs due to obsolete inventory or adversely affect our operating results and stock price.

We are subject to risks from our international sales and operations.

We have operations in Europe, Asia and Australia, and customers around the world. In addition, in December 2015 we acquired FiBest, a Japan-based merchant market component supplier of optical sub-assemblies. The FiBest Acquisition significantly increased our overall scope of operations and employee base in Japan. As a result, we are subject to regulatory, geopolitical and other risks associated with doing business outside the U.S. Global operations involve inherent risks, including currency controls, currency exchange rate fluctuations, tariffs, required import and export licenses, associated delays and other related international trade restrictions and regulations. Further, there is a risk that language barriers, cultural differences and other factors associated with our international operations may make them more difficult to manage effectively.

The legal system in many of the regions where we conduct business can lack transparency in certain respects relative to that of the U.S. and can accord local government authorities a higher degree of control and discretion over business than is customary in the U.S. This makes the process of obtaining necessary regulatory approvals and maintaining compliance inherently more

difficult and unpredictable. In addition, the protection accorded to proprietary technology and know-how under these legal systems may not be as strong as in the U.S., and, as a result, we may lose valuable trade secrets and competitive advantages. The cost of doing business in European jurisdictions can also be higher than in the U.S. due to exchange rates, local collective bargaining regimes and local legal requirements and norms regarding employee benefits and employer-employee relations, in particular. We are also subject to U.S. legal requirements related to our foreign operations, including the Foreign Corrupt Practices Act. Sales to customers located outside the U.S. accounted for 71.3% of our revenue for the fiscal year ended September 30, 2016.

Sales to customers located in the Asia Pacific region typically account for a substantial majority of our overall sales to customers located outside the U.S. We expect that revenue from international sales generally, and sales to the Asia Pacific region specifically, will continue to be a significant part of our total revenue. Therefore, any financial crisis or other major event causing business disruption in international jurisdictions generally, and the Asia Pacific region in particular, could negatively affect our future revenues and results of operations. For example, in fiscal 2017 we experienced decreased demand in China for our products targeting 2.5 Gigabit PON, metro/long-haul optical network deployments and other carrier-side applications, as carriers began migrating from 2.5 Gigabit to 10 Gigabit PON and the pace of provincial network deployments in China slowed. Further, in 2016 the U.S. Bureau of Industry and Security temporarily blocked exports of U.S. products to Chinese telecommunications OEM ZTE Corp., and issued an administrative subpoena to the largest such manufacturer, Huawei, which accounted for 15% of our revenue for fiscal year 2016, and which could possibly lead to similar restrictions in the future. A U.S. ban on exports to one or more large OEM customers could materially reduce our revenue and reduce the value of an investment in our common stock. Because the majority of our foreign sales are denominated in U.S. dollars, our products become less price-competitive in countries with currencies that are low or are declining in value against the U.S. dollar. Also, we cannot be sure that our international customers will continue to accept orders denominated in U.S. dollars. If they do not, our reported revenue and earnings will become more directly subject to foreign exchange fluctuations. Some of our customer purchase orders and agreements are governed by foreign laws, which may differ significantly from U.S. laws. We may be limited in our ability to enforce our rights under such agreements and to collect amounts owed to us.

The majority of our assembly, packaging and test vendors are located in Asia. We generally do business with our foreign assemblers in U.S. dollars. Our manufacturing costs could increase in countries with currencies that are increasing in value against the U.S. dollar. Also, our international manufacturing suppliers may not continue to accept orders denominated in U.S. dollars. If they do not, our costs will become more directly subject to foreign exchange fluctuations. From time to time we may attempt to hedge our exposure to foreign currency risk by buying currency contracts or otherwise, and any such efforts involve expense and associated risk that the currencies involved may not behave as we expect and we may lose money on such hedging strategies or not properly hedge our risk.

In addition, if terrorist activity, armed conflict, civil, economic or military unrest, embargoes or other economic sanctions or political instability occurs in the U.S. or other locations, such events may disrupt our manufacturing, assembly, logistics, security and communications, and could also result in reduced demand for our products. We have in the past and, may again in the future, experience difficulties relating to employees traveling in and out of countries facing civil unrest or political instability and with obtaining travel visas for our employees. Major health pandemics could also adversely affect our business and our customer order patterns. We could also be affected if labor issues disrupt our transportation arrangements or those of our customers or suppliers. There can be no assurance that we can mitigate all identified risks with reasonable effort. The occurrence of any of these events could have a material adverse effect on our operating results.
