He continued, "In the quarter, we had major customer wins for our secureWISE system, for our DirectScan system, and for our Exensio product and services. We significantly increased backlog in the quarter, which we expect to add to revenue for a number of years. Taking into account these positive factors, we reaffirm our 20% annual revenue growth target for 2026."

Conference Call

As previously announced, PDF Solutions will discuss these results on a live conference call beginning at 2:00 p.m. Pacific Time / 5:00 p.m. Eastern Time today. To participate on the live call, analysts and investors should pre-register at: https://register-conf.media-server.com/register/BIed4111b6aacf4d2e83be3b8b0e0f63aa. We encourage participants to dial into the call ten minutes ahead of the scheduled time. The teleconference will also be webcast simultaneously on the Company’s website at https://ir.pdf.com/webcasts. A replay of the conference call webcast will be available after the call on the Company’s investor relations website. A copy of this press release, including the disclosure and reconciliation of certain non-GAAP financial measures to the comparable GAAP measures, which non-GAAP measures may be used periodically by PDF Solutions’ management when discussing financial results with investors and analysts, will also be available on PDF Solutions’ website at http://www.pdf.com/press-releases on and following the date of this release.

Second Quarter 2026 Financial Commentary Available Online

A Management Report reviewing the Company’s second quarter 2026 financial results will be furnished to the Securities and Exchange Commission on Form 8-K and published on the Company’s website at http://ir.pdf.com/financial-reports. Analysts and investors are encouraged to review this commentary prior to participating in the conference call.

Information Regarding Use of Non-GAAP Financial Measures

In addition to providing results that are determined in accordance with accounting principles generally accepted in the United States of America ("GAAP"), PDF Solutions also provides certain non-GAAP financial measures. Non-GAAP gross profit and margin exclude stock-based compensation expense and the amortization of acquired technology under costs of revenues. Non-GAAP net income excludes stock-based compensation expense, amortization of acquired intangible assets, amortization of debt issuance costs and the effects of certain non-recurring items, such as expenses for certain legal proceedings, acquisition-related and integration costs, and their related income tax effects, as applicable, as well as adjustments for the valuation allowance for deferred tax assets and reconciling items. Non-GAAP financial measures are used by management internally to measure the Company’s profitability and performance. PDF Solutions’ management believes that these non-GAAP measures provide useful supplemental information to investors regarding the Company’s ongoing operations in light of the fact that none of these categories of expense and income has a current effect on the future uses of cash (with the exception of expenses related to certain legal proceedings and acquisition-related and integration costs) nor do they impact the generation of current or future revenues. These non-GAAP results should not be considered an alternative to, or a substitute for, GAAP financial information, and may differ from similarly titled non-GAAP measures used by other companies. In particular, these non-GAAP financial measures are not a substitute for GAAP measures of income or loss as a measure of performance, or to cash flows from operating, investing and financing activities as a measure of liquidity. Since management uses these non-GAAP financial measures internally to measure profitability and performance, PDF Solutions has included these non-GAAP measures to give investors an opportunity to see the Company’s financial results as viewed by management. A reconciliation of the comparable GAAP financial measures to the non-GAAP financial measures is provided at the end of the Company’s unaudited condensed consolidated financial statements presented below.

In the fourth quarter of 2025, the Company updated its presentation of revenue categories. The Company now presents revenue in the following categories: Platform and Volume-based. Platform revenue is derived from the following primary offerings: licenses for software (other than Cimetrix runtime licenses) and related software maintenance and technical support services; SaaS; engineering services; fixed fees associated with CV systems; and licenses and purchase contracts for DirectScan systems. Volume-based revenue is derived from Cimetrix runtime licenses, secureWISE data, and Gainshare. Prior periods Condensed Consolidated Statements of Operations have been reclassified to conform to the new revenue presentation. The change in presentation of revenue does not change the Company’s total revenues or costs of revenues.

The difference between the GAAP and non-GAAP income tax provisions is primarily due to the valuation allowance on a GAAP basis and non-GAAP adjustments. For example, on a GAAP basis, the Company does not receive a deferred tax benefit for foreign tax credits or research and development credits after the valuation allowance. The Company’s non-GAAP tax rate and resulting non-GAAP tax expense is not calculated with a full U.S. federal or state valuation allowance due to the Company’s cumulative non-GAAP income and management’s conclusion that it is more likely than not to utilize its net deferred tax assets (DTAs). Each reporting period, management evaluates the need for a valuation allowance and may place a valuation allowance against its U.S. net DTAs on a non-GAAP basis if it concludes it is more likely than not that it will not be able to utilize some or all of its U.S. DTAs on a non-GAAP basis.
