Insights

Revenue grew 26% with a swing to profitability and stronger margins.

PDF Solutions delivered Q1 2026 revenue of $60.1M, up 26% year over year, driven mainly by platform revenue of $50.9M. Recurring revenue represented 89% of total, indicating a solid, subscription-like base that can support more predictable performance.

Profitability improved meaningfully: GAAP operating margin reached 10% versus a (7%) margin in Q1 2025, while non-GAAP operating margin rose to 25%. GAAP net income was $4.8M and non-GAAP net income $12.6M, reflecting leverage on higher revenues and controlled operating expenses.

Management highlighted a backlog of $246.4M and reaffirmed its prior guidance for 20% annual revenue growth for 2026, alongside long-term model targets of 77% gross margin and 27% operating margin. Actual results will depend on execution, customer adoption, and broader semiconductor industry conditions discussed in the risk disclosures.

non-GAAP gross margin financial
"Non-GAAP gross margin for the first quarter of 2026 was 76%"
Non-GAAP gross margin is a measure of a company's profitability that shows how much money it makes from sales after subtracting the direct costs of producing its products or services, but without applying certain accounting adjustments required by standard rules. It helps investors understand the company's core earning ability by excluding items like one-time expenses or accounting changes. This metric provides a clearer picture of ongoing business performance beyond official financial reports.
operating margin financial
"GAAP operating margin for the first quarter of 2026 was 10%"
Operating margin shows how much profit a company makes from its core business activities after paying for costs like wages and materials. It’s useful because it tells you how efficiently a company is running—higher margins mean it keeps more money from each dollar of sales, which can indicate better management or stronger products.
backlog financial
"Ending backlog of $246.4 million"
A backlog is the amount of work or orders that a company has received but hasn't completed yet. It’s like a restaurant with many dishes to serve; the backlog shows how many orders are still waiting to be finished. It matters because a large backlog can indicate strong demand or potential delays in delivering products or services.
stock-based compensation expense financial
"Non-GAAP gross profit and margin exclude stock-based compensation expense"
Stock-based compensation expense is the value that a company records when it gives employees or executives shares or options to buy shares as part of their pay. It matters because it shows the true cost of paying employees this way, which can affect the company's profits and how investors see its financial health.
amortization of acquired intangible assets financial
"Non-GAAP net income excludes stock-based compensation expense, amortization of acquired intangible assets"
Amortization of acquired intangible assets is the gradual allocation of the purchase cost of non-physical items a company bought—like patents, brands, customer lists or software—spread over their expected useful life. It matters to investors because this accounting charge reduces reported profits even though it does not use cash at the time, so understanding it helps separate bookkeeping effects from underlying cash performance and valuation.
effective tax rate financial
"Effective Tax Rate | 18 % | 102 % | 63 %"
The effective tax rate is the percentage of a company's profits that it pays in taxes. It shows how much of its earnings go to taxes after all deductions and credits are considered. For investors, it indicates how much of the company's income is taken by taxes, impacting overall profitability and financial health.
Revenue $60.1M +26% YoY
GAAP Net Income $4.8M from $(3.0)M in Q1 2025
Non-GAAP Net Income $12.6M from $8.1M in Q1 2025
GAAP Operating Margin 10% from (7%) in Q1 2025
Non-GAAP Operating Margin 25% from 18% in Q1 2025
Guidance

Management reaffirmed its prior guidance for 20% annual revenue growth for 2026 and reiterated long-term model targets of 77% gross margin and 27% operating margin.

Financial Outlook

He continued, “In December 2025, at the latest PDF Solutions Analyst Day, we stated that PDF Solutions is instrumental in addressing research and development and manufacturing challenges of today’s semiconductor industry. This quarter’s results demonstrate the value of this strategy with a large fabless customer renewing its commitment to Exensio, a large semiconductor IDM developing its next generation test solution with us, and another eProbe tool shipped to an existing customer that is a leading-edge semiconductor company. We believe this continued market adoption reflects the market’s perception of the value our existing and new applications. With a strong product portfolio and momentum, we reaffirm our 20% annual revenue growth prior guidance for this year. We continue to make progress towards our long-term model target margins of 77% for gross margin and 27% for operating margin.”

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/BI1d55d4e14ae24f1194fc1069723cc6a1. 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.

 

 

First Quarter 2026 Financial Commentary Available Online

 

A Management Report reviewing the Company’s first 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.

Represents legal costs and expenses related to a certain arbitration proceeding, which are expected to continue until this matter is fully resolved.

 

(2) 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.

 GAAP / Non-GAAP Presentation

 

 

In addition to providing results that are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the Company 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, recovery from previously written-off property and equipment, 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 a 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 included herein.
