GAAP revenue for the quarter was $190.2 million, which was above the Company's expectations. The Company also had licensing billings of $71.5 million, product revenue of $96.8 million, and contract and other revenue of $21.8 million.

The Company’s provision for income taxes for the three months ended December 31, 2025 of $13.4 million was significantly higher than in the same period in 2024 partially due to the tax legislation enacted in the third quarter of 2025. The Company had GAAP diluted net income per share of $0.58 and non-GAAP diluted net income per share of $0.68. The Company’s basic share count was 108 million shares and its diluted share count was 110 million shares. Cash, cash equivalents, and marketable securities as of December 31, 2025 were $761.8 million, an increase of $88.5 million as compared to September 30, 2025, mainly due to $99.8 million in cash provided by operating activities, offset by $8.6 million paid for capital expenditures. 2026 First Quarter Outlook The Company will discuss its full revenue guidance for the first quarter of 2026 during its upcoming conference call. The following table sets forth the first quarter outlook for other measures.

(2) Licensing billings is an operational metric that reflects amounts invoiced to our licensing customers during the period, as adjusted for certain differences relating to advanced payments for variable licensing agreements. For the first quarter of 2026, the Company expects licensing billings to be between $66 million and $72 million. The Company also expects royalty revenue to be between $61 million and $67 million, product revenue to be between $84 million and $90 million, and contract and other revenue to be between $21 million and $27 million. Revenue is not without risk and achieving revenue in this range will require that the Company sign customer agreements for various product sales and solutions licensing, among other matters. The Company also expects operating costs and expenses to be between $121 million and $117 million. Additionally, the Company expects non-GAAP operating costs and expenses to be between $104 million and $100 million. These expectations also assume a tax rate of 16% and a diluted share count of 110 million, and exclude stock-based compensation expense of $15 million and amortization of acquired intangible assets of $2 million. Conference Call The Company’s management will discuss the results of the quarter during a conference call scheduled for 2:00 p.m. PT today.

Non-GAAP Financial Information In the commentary set forth above and in the financial statements included in this earnings release, the Company presents the following non-GAAP financial measures: cost of product revenue, operating expenses, operating income, operating margin, net income and diluted net income per share. In computing each of these non-GAAP financial measures, the following items were considered as discussed below: stock-based compensation expense, acquisition-related costs and retention bonus expense, amortization of acquired intangible assets, income tax adjustment, and certain other one-time adjustments. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations from these results should be carefully evaluated. Management believes the non-GAAP financial measures are appropriate for both its own assessment of, and to show investors, how the Company’s performance compares to other periods. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. A reconciliation from GAAP to non-GAAP results is included in the financial statements contained in this release. The Company’s non-GAAP financial measures reflect adjustments based on the following items: Stock-based compensation expense. These expenses primarily relate to employee stock purchase plans, and employee non-vested equity stock and non-vested stock units. The Company excludes stock-based compensation expense from its non-GAAP measures primarily because such expenses are non-cash expenses that the Company does not believe are reflective of ongoing operating results. Additionally, given the fact that other companies may grant different amounts and types of equity awards and may use different option valuation assumptions, excluding stock-based compensation expense permits more accurate comparisons of the Company’s results with peer companies. Acquisition-related costs and retention bonus expense. These expenses include all direct costs of certain acquisitions and the current periods’ portion of any retention bonus expense associated with the acquisitions. The Company excludes these expenses in order to provide better comparability between periods as they are related to acquisitions and have no direct correlation to the Company’s operations. Amortization of acquired intangible assets. The Company incurs expenses for the amortization of intangible assets acquired in acquisitions. The Company excludes these items because these expenses are not reflective of ongoing operating results in the period incurred. These amounts arise from the Company’s prior acquisitions and have no direct correlation to the operation of the Company’s core business. Income tax adjustment. For purposes of internal forecasting, planning and analyzing future periods that assume net income from operations, the Company estimates a fixed, long-term projected tax rate of approximately 20 percent and 22 percent for 2025 and 2024, respectively, which consists of estimated U.S. federal and state tax rates, and excludes tax rates associated with certain items such as withholding tax, tax credits, deferred tax asset valuation allowance and the release of any deferred tax asset valuation allowance. Accordingly, the Company has applied these tax rates to its non-GAAP financial results for all periods in the relevant years to assist the Company’s planning. On occasion in the future, there may be other items, such as significant gains or losses from contingencies, that the Company may exclude in deriving its non-GAAP financial measures if it believes that doing so is consistent with the goal of providing useful information to investors and management.
