Management Commentary

"In the fourth quarter, revenue was up 8% sequentially and up 27% year-over-year, driven by strong growth across our connectivity, broadband and infrastructure markets. Wi-Fi grew 40% sequentially and we exited Q4 on a $100 million annualized revenue run rate which we expect to build upon through 2022. Non-GAAP gross margin for Q4 improved to 61.7% driven by product mix shift towards higher value products. We are excited about our prospects for continued future growth driven by our comprehensive product portfolio, and the accelerating pace of new product launches particularly in connectivity, fiber-to-the home broadband, optical, and wireless infrastructure markets," commented Kishore Seendripu, Ph.D., Chairman and CEO.

First Quarter 2022 Business Outlook

The company expects revenue in the first quarter 2022 to be approximately $255 million to $265 million. The Company also estimates the following:

GAAP gross margin of approximately 57% to 59%;
Non-GAAP gross margin of approximately 61% to 63%;
GAAP operating expenses of approximately $108 million to $114 million;
Non-GAAP operating expenses of approximately $76 million to $82 million;
GAAP and non-GAAP interest and other expense of approximately $2.7 million.

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 specifically our current guidance for first quarter 2022 revenue, gross margins, and operating expenses as well as statements with respect to confidence in the Company's outlook for first quarter 2022) and statements concerning expectations of potential developments in our target markets, including (without limitation) management's views with respect to the prospects for and trends in our broadband, connectivity and infrastructure markets, and in particular, expectations concerning the development of our Wi-Fi market. 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. In particular, our future operating results are substantially dependent on our assumptions about market trends and conditions. Additional risks and uncertainties affecting our business and future operating results include, without limitation, increasing supply chain risks within our industry, including increases in shipping and material costs and substantial shipping delays resulting in extended lead-times; inflation trends in our supply chain and in the global economy generally; the on-going impact of the COVID-19 pandemic on our business, including the extent to which our broadband businesses will continue to benefit from work-from-home and similar initiatives as the pandemic abates; the impact of our indebtedness and limitations on our operating flexibility based on financial and operating covenants in the applicable term loan agreements, including (without limitation) debt covenant restrictions that may limit our ability to obtain additional financing, granting liens, undergoing certain fundamental changes, or making investments or certain restricted payments, and selling assets; risks associated with our ability to realize improved profitability from our Wi-Fi and Broadband assets business; intense competition in our industry; our dependence on a limited number of customers for a substantial portion of our revenues; potential uncertainties arising from continued consolidation among cable television and satellite operators in our target markets and continued consolidation among competitors within the semiconductor industry generally; 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; risks relating to intellectual property protection and the prevalence of intellectual property litigation in our industry; our reliance on a limited number of third party manufacturers; our lack of long-term supply contracts and dependence on limited sources of supply, which may be adversely affected by the pandemic; uncertainties concerning how end user markets for our products will develop, including in particular markets we have entered more recently such as broadband and Wi-Fi and 5G wireless and fiber-optic data center high-speed interconnect infrastructure markets but also existing markets which we previously referred to as connected home; and uncertainties concerning the outcome of global trade negotiations, export control limitations, and heightened geopolitical risks generally.

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 Quarterly Report on Form 10-Q for the quarter ended September 30, 2021, and our Current Reports on Form 8-K, as well as 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, 2021, which we expect to file soon. All forward-looking statements are based on the estimates, projections and assumptions of management as of February 2, 2022, 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 gross margin, operating expenses, operating expenses as a percentage of revenue, income from operations as percentage of revenue, and diluted earnings per share. These supplemental measures exclude the effects of (i) stock-based compensation expense; (ii) accruals related to our performance based bonus plan for 2021, which we currently intend to settle in shares of our common stock; (iii) accruals related to our performance based bonus plan for 2020, which we settled in shares of common stock in 2021; (iv) amortization of inventory fair value adjustments; (v) amortization of purchased intangible assets; (vi) research and development funded by others; (vii) acquisition and integration costs related to our acquisitions; (viii) professional fees and settlement costs related to IP and commercial litigation matters; (ix) severance and other restructuring charges; (x) impairment losses on intangible assets; (xi) loss from extinguishment of debt; (xii) other non-recurring interest and other income (expenses), net attributable to acquisitions and (xiii) non-cash income tax benefits and expenses. 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. 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.

Bonuses under our executive and non-executive bonus programs have been excluded from our non-GAAP net income for all periods reported. Bonus payments for the 2020 performance periods were settled through the issuance of shares of common stock under our equity incentive plans in February 2021. We currently expect that bonus awards under our fiscal 2021 program will be settled in common stock in the first quarter of fiscal 2022.

Expenses incurred in relation to acquisitions include amortization of purchased intangible assets, amortization of inventory fair value adjustments, acquisition and integration costs primarily consisting of professional and consulting fees, and amortization of discount on deferred purchase price payments to interest expense. Gains related to acquisitions include a gain on sale of an investment in a privately-held entity included in interest and other income.

Research and development funded by others represents proceeds received under contracts for jointly funded R&D projects to develop technology that may be commercialized into a product in the future. Such proceeds have not yet been recognized in GAAP results as the Company may be required to repay all or a portion of the funds provided by the other party under certain conditions. Management believes it is not probable that it will trigger such conditions.

Impairment losses relate to certain intangible assets.

Restructuring charges incurred are related to our restructuring plans which eliminate redundancies and primarily include severance and restructuring costs related to impairment of leased right-of-use assets or from exiting certain facilities.

Loss on extinguishment of debt is related to the charge-off of remaining unamortized debt discount and issuance costs on debt we repaid early with proceeds from a new term loan in June 2021.

Expenses incurred in relation to our intellectual property and commercial litigation include professional fees incurred.

Income tax benefits and expense adjustments are those that do not affect cash income taxes payable.

Reconciliations of non-GAAP measures for the historic periods disclosed in this press release appear below. Because of the inherent uncertainty associated with our ability to project future charges, particularly related to stock-based compensation and its related tax effects as well as potential impairments, we have not provided a reconciliation for non-GAAP guidance provided for the first quarter 2022.
