LOWELL, MA, January 26, 2016 – M/A-COM Technology Solutions Holdings, Inc.

First Quarter Fiscal Year 2016 Adjusted Non-GAAP Results

Management Commentary

John Croteau, MACOM’s President and Chief Executive Officer, stated, “During the first quarter, our business performed as expected with revenue across Networks, Multi-market and Aerospace and Defense coming in essentially flat quarter-on-quarter.

Most notable, during the quarter we achieved a major milestone for the core MACOM business, reaching 60 percent adjusted gross margin excluding the impact of the two recent acquisitions. Our new, high-margin products have fueled the steady expansion of our gross margin and enabled us to achieve the target operating model we set for ourselves two years ago.”

Mr. Croteau concluded, “Comparing our second quarter guidance to our fiscal third quarter results six months ago, which included the automotive business that we divested last August, I’m proud to say that in five months we’ve replaced that revenue and EPS contribution and repositioned the company with higher quality revenue, faster growth and stronger earnings potential.”

Business Outlook

For the fiscal second quarter ending April 1, 2016, MACOM expects revenue to be in the range of $128.0 million to $132.0 million. Adjusted gross margin is expected to be between 56 and 59 percent, and adjusted earnings per share between $0.42 and $0.45 on an anticipated 56.5 million diluted shares outstanding.

Forward-looking statements include, among others, information concerning our stated business outlook and future results of operations, our statements regarding our expectations for our recent acquisitions, statements about our replacement of the contributions of our former automotive business and repositioning of our company with higher quality revenue, faster growth and stronger earnings potential and any other statements regarding future trends, business strategies, competitive position, industry conditions, acquisitions and market opportunities. Forward-looking statements include all statements that are not historical facts and generally may be identified by terms such as “anticipates,” “believes,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “seeks,” “should,” “will,” “would” or similar expressions and the negatives of those terms.

Forward-looking statements contained in this press release reflect MACOM’s current views about future events and are subject to risks, uncertainties, assumptions and changes in circumstances that may cause those events or our actual activities or results to differ materially from those expressed in any forward-looking statement. Although MACOM believes that the expectations reflected in the forward-looking statements are reasonable, it cannot and does not

guarantee future events, results, actions, levels of activity, performance or achievements. Readers are cautioned not to place undue reliance on these forward-looking statements. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements, including greater than expected dilutive effect on earnings of our equity issuances, outstanding indebtedness and related interest expense and other costs, the potential that the expected rollout of fiber-to-the-home network technology or other new network technology deployments in China, Japan and other geographies fails to occur, occurs more slowly than we expect or does not result in the amount or type of new business we anticipate, lower than expected demand in any or all of our primary end markets or from any of our large OEM customers based on seasonal effects, macro-economic weakness or otherwise, our failure to realize the expected economies of scale, lowered production cost and other anticipated benefits of our previously announced GaN intellectual property licensing program or InP laser production capacity expansion program, the potential for defense spending cuts, program delays, cancellations or sequestration, failures or delays by any customer in winning business or to make purchases from us in support of such business, lack of adoption or delayed adoption by customers and industries we serve of Active Antennas, GaN, InP lasers or other solutions offered by us, failures or delays in porting and qualifying GaN or InP process technology to our Lowell, MA fabrication facility or third party facilities, lower than expected utilization and absorption in our manufacturing facilities, lack of success or slower than expected success in our new product development efforts, failure of any announced transaction to close in accordance with its terms, failure to successfully integrate acquired companies, technologies or products or realize synergies associated with acquisitions, the potential that we will experience difficulties in managing the personnel and operations associated with our acquisitions, loss of business due to competitive factors, product or technology obsolescence, customer program shifts or otherwise, lower than anticipated or slower than expected customer acceptance of our new product introductions, the potential for a shift in the mix of products sold in any period toward lower-margin products or a shift in the geographical mix of our revenues, the potential for increased pricing pressure based on competitive factors, technology shifts or otherwise, the impact of any executed or abandoned acquisition, divestiture, joint venture, financing or restructuring activity, the impact of supply shortages or other disruptions in our internal or outsourced supply chain, the impact of changes in export, environmental or other laws applicable to us, the relative success of our cost-savings initiatives, the potential for inventory obsolescence and related write-offs, the expense, business disruption or other impact of any current or future investigations, administrative actions, litigation or enforcement proceedings we may be involved in, the potential loss of access to any in-licensed intellectual property or inability to license technology we may require on reasonable terms, and the impact of any claims of intellectual property infringement or misappropriation, which could require us to pay substantial damages for infringement, expend significant resources in prosecuting or defending such matters or developing non-infringing technology, incur material liability for royalty or license payments, or prevent us from selling certain of our products, as well as those factors described in “Risk Factors” in MACOM’s filings with the Securities and Exchange Commission (SEC), including its Annual Report on Form 10-K for the fiscal year ended October 2, 2015 as filed with the SEC on November 24, 2015. MACOM undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Non-GAAP Financial Measures

In addition to GAAP reporting, MACOM provides investors with adjusted non-GAAP financial information. Adjusted items include revenue, gross profit, gross margin, operating margin, operating income, net income, earnings per share, Adjusted EBITDA and other data calculated on a non-GAAP basis. This non-GAAP information excludes discontinued operations, the impact of fair value accounting in merger and acquisitions (M&A) of businesses, M&A costs, including acquisition and related integration costs, certain cost savings from synergies expected from M&A activities, income and expenses from transition services related to M&A activities, expected amortization of acquisition-related intangibles, share-based and other non-cash compensation expense, certain cash compensation, restructuring charges, litigation settlement and costs, changes in the carrying values of assets and liabilities measured at fair value, contingent consideration, amortization of debt discounts and issuance costs, debt settlement costs, other non-cash expenses, earn-out costs, restructuring costs and certain income tax items. Management does not believe that the adjusted items are reflective of MACOM’s underlying performance. The adjustment of these and other similar items from MACOM’s non-GAAP presentation should not be interpreted as implying that these items are non-recurring, infrequent or unusual. These and other similar items are also excluded from Adjusted EBITDA, which is non-GAAP earnings before interest, income taxes, depreciation and amortization. MACOM believes this adjusted non-GAAP financial information provides additional insight into these items and MACOM’s performance and has, therefore, chosen to provide this information to investors for a consistent basis of comparison and to help them evaluate the results of MACOM’s operations and enable

more meaningful period to period comparisons. These adjusted non-GAAP measures may be different than similar measures used by other companies and should be considered in addition to, not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and adjusted non-GAAP financial data used in this earnings release is included in the supplemental financial data attached to this press release.
