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 expectations for third quarter 2012 revenues; trends and growth opportunities in specific product markets such as cable and terrestrial applications; and opportunities associated with new product offerings and our strategy to expand our addressable market. These forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause actual results to differ materially 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 and operating results, include, among others, intense competition in our industry; uncertainties concerning how end user markets for our products will develop, including end user markets for the cable and terrestrial applications of our products as well as end user markets for products currently in development; 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; our dependence on a limited number of customers for a substantial portion of our revenues; the timing and development of the global transition from analog to digital television; intellectual property risks; our lack of long-term supply contracts and dependence on limited sources of supply; and potential decreases in average selling prices for our products. In addition, with respect to our recently completed export control compliance review, we face risks associated with the potential for government enforcement proceedings and the assessment of civil or criminal fines or penalties materially in excess of those currently estimated and accrued. 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 and Quarterly Report on Form 10-Q. Additional risks, uncertainties, and other information will be contained in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2012, which MaxLinear expects to file with the SEC in August 2012.

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 2012, which if achieved will be settled in stock in 2013; (iii) expenses associated with our acquisition of certain new market related technology licenses; and (iv) estimated fines and penalties and professional fees related to our previously disclosed export compliance and intellectual property 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 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.

Any bonus payments under our 2012 bonus plans will be settled through the issuance of Class A common stock under our equity incentive plans. While we include the dilutive impact of equity awards in weighted average shares outstanding, if any, the expense associated with stock-based awards reflects a non-cash charge that we exclude from non-GAAP net income.

Expenses incurred in relation to the purchase of certain new market related technology licenses, intellectual property litigation and estimated fines, penalties and professional fees related to export compliance matters are unrelated to our underlying business. Therefore, we do not believe these are indicative of our core operating performance and exclude these expenses in management evaluations of our business.

Expenses incurred in relation to our export compliance review include (i) charges relating to estimates of potential export compliance fines and penalties and (ii) professional fees incurred as a result of the Audit Committee’s review and the final voluntary disclosures submitted to governmental agencies.

Expenses incurred in relation to our intellectual property litigation with Silicon Laboratories include professional fees incurred. The Company believes the lawsuit is without merit and intends to vigorously defend itself.

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