Non-GAAP gross margin for the third quarter of 2022 was 72%, compared to 69% for the second quarter of 2022 and 66% for the third quarter of 2021.

On a GAAP basis, net income for the third quarter of 2022 was $1.4 million, or $0.04 per basic and diluted share, compared to a net loss of $1.1 million, or ($0.03) per basic and diluted share, for the second quarter of 2022, and net loss of $2.4 million, or ($0.06) per basic and diluted share, for the third quarter of 2021.

Cash, cash equivalents and short-term investments at September 30, 2022, were $116.1 million, compared to $140.2 million at December 31, 2021, a decrease of $24.1 million, primarily due to the $22.5 million of share repurchases during the nine months ended September 30, 2022. Cash provided by operating activities was $1.4 million for the third quarter of 2022.

Financial Outlook and Recent Accomplishments

There are challenges in the semiconductor environment, in part due to geopolitical factors, and no business is immune to macro and regulatory headwinds. Despite these challenges, the Company expects full year 2022 total revenue growth to approach 30% on a year over year basis. Backlog at the end of the year is expected to be strong, in part due to strong bookings in the fourth quarter that have already exceeded $100.0 million, which will be recognized as revenue over multiple years.

“We are proud of our performance in 2022 to date and believe we are positioned well to deliver long-term value to our stockholders. We are continuing to evaluate our 2023 targets and will provide an update at the beginning of next year, consistent with past practice,” said John Kibarian, CEO and President.

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 gross profit excludes stock-based compensation expense and the amortization of acquired technology. Non-GAAP net income excludes the effects of certain non-recurring items, including expenses related to an arbitration proceeding for a disputed contract with a customer, 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 valuation allowance for deferred tax assets. 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 expenses related to an arbitration proceeding for a disputed contract with a customer) 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 press release and the planned conference call include forward-looking statements regarding the Company’s future expected business performance and financial results, including expectations about total revenue growth for full year 2022 and expected revenue from new bookings, that are subject to future events and circumstances. Actual results could differ materially from those expressed in these forward-looking statements.

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 R&D credits after 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 DTA 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 US DTAs on a non-GAAP basis.
