Fourth Quarter and Fiscal Year 2014 Financial Results

Fourth Quarter 2014 Revenue Grows Approximately 3 Percent Year-over-Year to $32.5 Million, Bringing Full-Year 2014

Revenue to $133.1 Million, Representing Growth of 11.3 Percent

Carlsbad, Calif. – February 9, 2015 – MaxLinear, Inc. (NYSE: MXL), a provider of integrated, radio-frequency (RF) and mixed-signal integrated circuits for broadband communications applications, today announced financial results for the fourth quarter and year ended December 31, 2014.

Management Commentary

“We are pleased to announce that in the fourth quarter, we realized revenue of $32.5 million, consistent with our prior guidance, and representing growth of three percent year-over-year. These results bring to close a successful year in which we grew our annual revenue by 11 percent and delivered strong cash flow from operations of approximately $12.2 million, or 9.2 percent of revenue,” commented Kishore Seendripu, Ph.D., Chairman and CEO.

“Our revenue growth in 2014 reflected continued momentum in cable across both DOCSIS 3.0 modems and gateways, along with double-digit growth of our terrestrial revenues driven by strong shipments of ISDB-T tuner-demodulator receiver shipments into pay TV operators in Latin America, as well as continued gains in hybrid television.”

“Entering 2015, we are experiencing growing shipments and backlog for our technology-leading satellite gateway and digital channel-stacking solutions. We believe our satellite gateway and digital outdoor unit products constitute the next major growth driver for MaxLinear for the next several years,” continued Dr. Seendripu.

“We are excited about the significant progress we have made in implementing our strategy of opening up large new addressable markets for our RF and analog/mixed signal technology platform, primarily in wireless and wireline network infrastructure. In the fourth quarter of 2014, we closed the acquisition of Physpeed, a privately held developer of high-speed physical layer optical interconnect products addressing emerging 100 Gigabit software-defined networking (SDN) applications in the enterprise, datacom, and telecommunications infrastructure markets.”

“Earlier this month, we announced that we had entered a definitive agreement to acquire Entropic Communications, a pioneer in MoCA and analog channel stacking switches for the satellite pay-TV market. Combined with our organic growth initiatives addressing wireless microwave backhaul applications, we believe we have set a stage for strong future growth, while diversifying revenues across broadband and infrastructure markets. We are very proud of the progress we have made in establishing MaxLinear as a broad-based leader in RF and analog/mixed signal technology products. As we enter 2015, we couldn’t be more excited for the future of MaxLinear.”

Cautionary Note Concerning Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include, among others, statements concerning our future financial performance (including our current guidance for first quarter 2015 revenue and gross profit percentage); trends and growth opportunities in specific product markets for cable, terrestrial, satellite, and other applications; and opportunities associated with new product offerings and our strategy to expand our addressable market, including our recent acquisition of Physpeed and our entering a definitive agreement to acquire Entropic. These forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause actual results to be materially different from any future results expressed or implied by the forward-looking statements. Forward-looking statements are based on management’s current, preliminary expectations and are subject to various risks and uncertainties. Risks and uncertainties affecting our business, operating results, financial condition, and stock price, include, among others, intense competition in our industry; our dependence on a limited number of customers for a substantial portion of our revenues; uncertainties concerning how end user markets for our products will develop, including end user markets for the cable and satellite applications of our products as well as end user markets for products currently in development; potential uncertainties arising from continued consolidation among cable television operators; integration risks associated with our acquisition of Physpeed; our ability to develop and introduce new and enhanced products on a timely basis and achieve market acceptance of those products, particularly as we seek to expand outside of our historic markets; potential decreases in average selling prices for our products; limited trading volumes; risks relating to intellectual property protection and the prevalence of intellectual property litigation in our industry, including pending litigation against us by a third party with the United States International Trade Commission and in United States District Court in Delaware; our reliance on a limited number of third party manufacturers; and our lack of long-term supply contracts and dependence on limited sources of supply. Risks relating to our potential acquisition of Entropic include the potential failure of MaxLinear’s or Entropic’s stockholders to approve the proposed merger transaction; the potential failure to obtain regulatory approvals related to the transaction; the challenges and costs of closing, integrating, restructuring, and achieving currently anticipated synergies; the ability to retain key employees, customers, and suppliers of Entropic or MaxLinear while the acquisition is pending and thereafter; and other factors generally affecting the business, operating results, and financial condition of either MaxLinear or Entropic or the combined company . In addition to these risks and uncertainties, investors should review the risks and uncertainties contained in our filings with the Securities and Exchange Commission (SEC), including our most recent Annual Report on Form 10-K for the year ended December 31, 2013; our subsequent Quarterly Reports on Form 10-Q; and our Current Reports on Form 8-K. In addition, when available, investors should review the information to be set forth under the caption “Risk Factors” in MaxLinear’s Annual Report on Form 10-K for the year ended December 31, 2014, which MaxLinear expects to file with the SEC in February 2015. All forward-looking statements are based on the estimates, projections and assumptions of management as of February 9, 2015, and MaxLinear is under no obligation (and expressly disclaims any such obligation) to update or revise any forward-looking statements whether as a result of new information, future events, or otherwise.

Use of Non-GAAP Financial Measures

To supplement our unaudited consolidated financial statements presented on a basis consistent with GAAP, we disclose certain non-GAAP financial measures, including non-GAAP net income (loss), income (loss) from operations, gross profit, and earnings (loss) per share. These supplemental measures exclude the effects of (i) stock-based compensation expense and its related tax effect, if any; (ii) an accrual related to our performance based bonus plan for 2014, which if achieved we intend to settle in stock in 2015; (iii) an accrual related to our performance based bonus plan for 2013, which was settled in stock in May 2014; (iv) impairment of production masks; (v) amortization of purchased intangible assets; (vi) acquisition costs related to our recently completed acquisition of Physpeed and our potential acquisition of Entropic; (vii) restricted merger proceeds; and (viii) professional fees and settlement costs related to our previously disclosed IP litigation matters. These non-GAAP measures are not in accordance with and do not serve as an alternative for GAAP. We believe that these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with our GAAP results of operations. These non-GAAP measures should only be viewed in conjunction with corresponding GAAP measures. We compensate for the limitations of non-GAAP financial measures by relying upon GAAP results to gain a complete picture of our performance.

We believe that non-GAAP financial measures can provide useful information to both management and investors by excluding certain non-cash and other one-time expenses that are not indicative of our core operating results. Among other uses, our management uses non-GAAP measures to compare our performance relative to forecasts and strategic plans and to benchmark our performance externally against competitors. In addition, management’s incentive compensation will be determined in part using these non-GAAP measures because we believe non-GAAP measures better reflect our core operating performance.

The following are explanations of each type of adjustment that we incorporate into non-GAAP financial measures:

Stock-based compensation expense relates to equity incentive awards granted to our employees, directors, and consultants. Our equity incentive plans are important components of our employee incentive compensation arrangements and are reflected as expenses in our GAAP results. Stock-based compensation expense has been and will continue to be a significant recurring expense for MaxLinear. In addition, we exclude the related tax effect of stock-based compensation expense, if any, from non-GAAP net income.

Bonus payments under our executive and non-executive bonus programs have been excluded from our non-GAAP net income for 2014 and 2013. Bonus payments for the 2013 performance period were settled through the issuance of shares of Class A common stock under our equity incentive plans in May 2014, and we currently expect that any bonus payments under our 2014 programs will also be settled in stock. While we include the dilutive impact of equity awards in weighted average shares outstanding, the expense associated with stock-based awards reflects a non-cash charge that we exclude from non-GAAP net income.

Restricted stock units to be granted under our equity incentive plan to Physpeed continuing employees if certain 2015 and 2016 revenue targets are met contingent upon continued employment reflect a non-cash charge that we exclude from non-GAAP net income.

Expenses incurred in relation to impairment of production masks reflect costs that were previously capitalized but for which future use is no longer expected.

Expenses incurred in relation to acquisitions include amortization of purchased intangible assets, acquisition costs primarily consisting of professional fees and restricted merger proceeds which represent merger proceeds held back from the owners of Physpeed which will be paid on a quarterly basis through October 31, 2016.

Expenses incurred in relation to our intellectual property litigation include professional fees incurred and a one-time settlement payment.

The acquisition of Physpeed resulted in a net deferred tax liability, which led to the release of valuation allowance and a benefit for income taxes for the three and twelve months ended December 31, 2014.

Reconciliations of non-GAAP measures disclosed in this press release appear below.
