⁽¹⁾	See "Reconciliation of GAAP Forward-Looking Estimates to Non-GAAP Forward-Looking Estimates" table included below. Note that the applicable non-GAAP measures are presented and that revenue is solely presented on a GAAP basis.

For the third quarter of 2026, the Company expects revenue to be between $210 million and $216 million. The Company also expects product revenue to be between $110 million and $116 million, royalties revenue to be between $69 million and $75 million, and contract and other revenue to be between $25 million and $31 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 GAAP operating costs and expenses to be between $137 million and $133 million and non-GAAP operating costs and expenses to be between $119 million and $115 million. The Company expects interest and other income to be $7 million. These expectations also assume a GAAP tax rate of 18.7%, a non-GAAP tax rate of 16% and a diluted share count of 110 million shares, and exclude stock-based compensation expense of $15.7 million, amortization of acquired intangible assets of $1.5 million and other one-time adjustments of $0.8 million.

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, gross margin, operating margin, net income and diluted net income per share (diluted earnings per share). In computing each of these non-GAAP financial measures, the following items were considered as discussed below: stock-based compensation expense, restructuring charges, acquisition-related costs, amortization of acquired intangible assets, facility closure costs, 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 valuation assumptions, excluding stock-based compensation expense permits more accurate comparisons of the Company’s results with peer companies.

Restructuring charges. These charges include severance, exit costs and other related costs. The Company excludes these charges because such charges are not directly related to ongoing business results and do not reflect expected future operating expenses.

Acquisition-related costs. 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.

Facility closure costs. These charges consist of exit costs associated with building leases that were abandoned. The Company excludes these charges because such charges are not directly related to ongoing business results and do not reflect expected future operating expenses.

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 16 percent and 20 percent for 2026 and 2025, 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.
