Forward-Looking Statements
Certain statements in this press release constitute “forward-looking statements” regarding our industry, our strategic position, and our financial and operating results. These forward-looking statements are subject to a number of risks and uncertainties that could cause actual results, performance or achievements to differ materially. Please refer to Item 1A “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended October 31, 2024 and other subsequent filings with the Securities and Exchange Commission. These documents contain and identify important factors that could cause our actual results to differ materially from those contained in these forward-looking statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, or achievements. We are under no duty to update any of the forward-looking statements after the date of this release to conform these statements to actual results.
Non-GAAP Financial Measures
Non-GAAP Net Income attributable to Photronics, Inc. shareholders and non-GAAP diluted earnings per share attributable to Photronics, Inc. shareholders are “non-GAAP financial measures” as such term is defined by Regulation G of the Securities and Exchange Commission, and may differ from similarly named non-GAAP financial measures used by other companies. The attached financial supplement reconciles Photronics, Inc. financial results under GAAP to non-GAAP financial information. We believe these non-GAAP financial measures that exclude certain items are useful for analysts and investors to evaluate our on-going performance because they enable a more meaningful comparison of our projected performance with our historical results. These non-GAAP metrics are not a measure of consolidated operating results under U.S. GAAP and should not be considered as an alternative to Net income (loss), Net income (loss) per share, or any other measure of consolidated results under U.S. GAAP. The items excluded from these non-GAAP metrics, but included in the calculation of their closest GAAP equivalent, are significant components of the condensed consolidated statement of income and must be considered in performing a comprehensive assessment of overall financial performance. Please refer to the non-GAAP reconciliations below.
