**Item 7.01. Regulation FD Disclosure.**

On November 6, 2025, PDF Solutions, Inc. ("PDF Solutions") filed its Quarterly Report on Form 10-Q for the quarter ended September 30, 2025 (the "Form 10-Q"). PDF Solutions subsequently discovered that the Form 10-Q contained an error in the Financial Highlights section of Part I., Item 2. The increase in Analytics revenue for the nine-month period ended September 30, 2025 as compared to the nine-month period from the prior year was incorrectly characterized as "partially offset by a decrease in revenues from DFI systems."

The disclosure regarding the increase in PDF Solutions' Analytics revenue for the nine-month period ended September 30, 2025 as compared to the nine-month period from the prior year should have attributed part of the increase to an increase in revenues from DFI systems and stated that the total increase was partially offset by a decrease in revenue from Exensio software licenses.

The information in this Item 7.01 is being furnished and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities under that Section, and shall not be deemed incorporated by reference into any filing of PDF Solutions under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

**SIGNATURES**

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
