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, non-GAAP operating expenses, non-GAAP operating expenses as a percentage of net revenue, non-GAAP income from operations as percentage of revenue, and non-GAAP 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 2023, which we currently intend to settle in shares of our common stock; (iii) accruals related to our performance-based bonus plan for 2022, which we settled in shares of common stock in 2023; (iv) amortization of purchased intangible assets; (v) research and development funded by others; (vi) acquisition and integration costs related to our acquisitions; (vii) impairment of intangible assets; (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. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP financial measures. Non-GAAP financial measures are subject to limitations, and should be read only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. 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. 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 we believe 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 2022 performance periods were settled through the issuance of shares of common stock under our equity incentive plans in February 2023. We currently expect that bonus awards under our fiscal 2023 program will be settled in common stock in the first quarter of fiscal 2024.

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 contingent consideration or 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.

Impairment losses are related to abandonment of acquired or purchased 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.

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, we are also unable to predict their probable significance, 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, in reliance on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K, we have not provided a reconciliation for non-GAAP guidance provided for the second quarter 2023.
