M/A-COM Technology Solutions Holdings, Inc. Reports First Quarter

Fiscal Year 2014 Financial Results

LOWELL, MA, February 10, 2014 - M/A-COM Technology Solutions Holdings, Inc. (NASDAQ: MTSI) (“MACOM”), a leading supplier of high performance analog semiconductor solutions, today reported its financial results for its first fiscal quarter ended January 3, 2014.

First Quarter Fiscal Year 2014 GAAP Results

MACOM completed its previously announced acquisition of Mindspeed Technologies, Inc. (the “Acquisition”) during the fiscal first quarter. MACOM’s reported GAAP operating expenses included incremental charges for Acquisition-related restructuring costs and other related expenses. MACOM financed the Acquisition using cash on hand and borrowings from its available line of credit.

The Acquisition contributed $1.3 million in revenue, lowered operating income by $16.3 million and reduced earnings per diluted share by $0.34 in the first quarter of fiscal 2014.

At January 3, 2014, cash and equivalents totaled $66.4 million, outstanding long-term debt was $220.0 million and MACOM had credit availability of $80.0 million.

MACOM’s first quarter fiscal year 2014 included 14 weeks versus 13 weeks in the first quarter fiscal year 2013.

First Quarter Fiscal Year 2014 Non-GAAP Results

The Acquisition lowered operating income by $0.7 million and reduced earnings per diluted share by $0.01 in the first quarter of fiscal 2014.

John Croteau, Chief Executive Officer of MACOM stated, “Revenue and earnings per share for the first quarter were in line with our expectations, and non-GAAP gross margin exceeded the high end of our guidance, marking our fifth consecutive quarter of non-GAAP margin expansion. During the quarter, we saw improvements in our Carrier Networks and Aerospace and Defense markets, offset by softness in Multi-Market, which we attribute to the weakness in test and instrumentation.”

Mr. Croteau noted, “Highlighting the quarter was the close of the Mindspeed acquisition on December 18^th. We have made great progress on our 100-day integration plan, and continue to expect the acquisition to deliver significant accretion in fiscal 2014. We remain focused on realizing potential synergies, capitalizing on cross-selling opportunities and optimizing our combined operations for improved profitability over the remainder of the fiscal year.”

Business Outlook

For the second fiscal quarter ending April 4, 2014, MACOM currently expects revenue to be in the range of $103 million and $107 million, non-GAAP gross margin between 48 and 52 percent, and non-GAAP earnings per diluted share between $0.26 and $0.28, based on an expected 49.3 million shares outstanding.

Non-GAAP Financial Measures

In addition to GAAP reporting, MACOM provides investors with non-GAAP financial information, including gross margin, operating margin, operating income, net income, earnings per share and other data calculated on a non-GAAP basis. This non-GAAP information excludes discontinued operations, the impact of fair value accounts in acquisition of businesses, merger and acquisition costs, including related integration costs, 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 liabilities measured at fair value, contingent consideration, other non-cash expenses, earn-out costs, exited leased facility costs and certain income tax items. Management does not believe that the excluded items are reflective of MACOM’s underlying performance. The exclusion 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. MACOM believes this non-GAAP financial information provides additional insight into MACOM’s on-going performance and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of MACOM’s on-going operations and enable more meaningful period to period comparisons. These non-GAAP measures are provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release.
