The call will be simultaneously web cast on PDF Solutions’ website at http://ir.pdf.com/webcasts. A replay of the web cast will be available at the same website address beginning approximately two hours after completion of the live call. 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 /press-releases following the date of this release.

FOURTH QUARTER AND FULL YEAR 2019 FINANCIAL COMMENTARY AVAILABLE ONLINE

A Management Report reviewing the Company’s fourth quarter and full year 2019 financial results will be furnished to the SEC 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 webcast.

INFORMATION REGARDING USE OF NON-GAAP FINANCIAL MEASURES

In addition to providing results that are determined in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP), PDF Solutions also provides certain non-GAAP financial measures. Non-GAAP net income (loss) excludes the effects of non-recurring items (including adjustment to contingent consideration related to acquisition, write-down in value of property and equipment, restructuring charges and severance payments), stock-based compensation expense, amortization of acquired technology and other acquired intangible assets, and their related income tax effects, as applicable, as well as adjustments for the non-cash portion of income taxes. These 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 has a current effect on the future uses of cash (with the exception of certain non-recurring items) 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 financial statements presented below.

FORWARD-LOOKING STATEMENTS

The statements planned to be made on the planned conference call regarding the Company’s future expected business performance and financial results are forward looking and are subject to future events and circumstances. Actual results could differ materially from those expressed in these forward-looking statements. Risks and uncertainties that could cause results to differ materially include risks associated with: customers’ production volumes under contracts that provide Gainshare royalties, cost and schedule of new product development; continued adoption of the Company’s solutions by new and existing customers; project milestones or delays and performance criteria achieved; the provision of technology and services prior to the execution of a final contract, the potential impact of the coronavirus on our operations in China or demand for our products by customers in China; and other risks set forth in PDF Solutions’ periodic public filings with the Securities and Exchange Commission, including, without limitation, its Annual Reports on Form 10-K, most recently filed for the year ended December 31, 2018, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K and amendments to such reports. The forward-looking statements made in the conference call are made as of the date hereof, and PDF Solutions does not assume any obligation to update such statements nor the reasons why actual results could differ materially from those projected in such statements.  The Company has not filed its Form 10-K for the year ended December 31, 2019. As a result, all financial results described in this earnings release should be considered preliminary, and are subject to change to reflect the completion of our audit and any necessary adjustments or changes in accounting estimates that are identified prior to the time the Company files the Form 10-K.
