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 2022, which we currently intend to settle in shares of our common stock; (iii) accruals related to our performance-based bonus plan for 2021, which we settled in shares of common stock in 2022; (iv) amortization of purchased intangible assets; (v) research and development funded by others; (vi) acquisition and integration costs related to our acquisitions; (vii) professional fees and settlement costs related to IP and commercial litigation matters; (viii) severance and other restructuring charges; (ix) other non-recurring interest and other income (expenses), net attributable to acquisitions and (x) 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 2021 performance periods were settled through the issuance of shares of common stock under our equity incentive plans in February 2022. We currently expect that bonus awards under our fiscal 2022 program will be settled in common stock in the first quarter of fiscal 2023.

Expenses incurred in relation to acquisitions include amortization of purchased intangible assets, acquisition and integration costs primarily consisting of professional and consulting fees, and accretion of discount on deferred purchase price payments to interest expense.

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. Initially such proceeds may not yet be recognized in GAAP results if, pursuant to contract terms, 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. Once such conditions have been resolved, the proceeds are recognized in GAAP results, and accordingly, reversed from non-GAAP results.

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.

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, a quantitative reconciliation is not available without unreasonable efforts and accordingly we have not provided a reconciliation for non-GAAP guidance provided for the third quarter 2022.
