Photronics Reports First Quarter Fiscal 2023 Results

BROOKFIELD, Conn. February 20, 2023 (GLOBE NEWSWIRE) — Photronics, Inc. (NASDAQ:PLAB), a worldwide leader in photomask technologies and solutions, today reported financial results for its fiscal first quarter 2023 ended January 29, 2023.

“We made a great start to 2023 and grew revenue sequentially, as both IC and FPD high-end businesses improved due to ongoing design-driven demand,” said Frank Lee, chief executive officer. “IC growth was driven by high-end demand from Asian foundries; FPD benefited from increased G10.5+ demand and continued strength in mobile displays.

“Profit margins were somewhat softer than the previous quarter primarily due to less favorable mix and somewhat lower customer premiums to accelerate delivery. Operating cash generation continued strong, which enables us to continue investing in organic growth and maintain a strong balance sheet to support our strategy and help navigate economic uncertainty. I am proud of the performance of the entire Photronics team.”

Non-GAAP Financial Measures

Non-GAAP Net Income attributable to Photronics, Inc. shareholders and non-GAAP earnings per share, Free Cash Flow, LTM Free Cash Flow, and Net Cash are "non-GAAP financial measures" as such term is defined by 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 future on-going performance because they enable a more meaningful comparison of our projected performance with our historical results. These non-GAAP metrics are not intended to represent funds available for our discretionary use and are not intended to represent, or be used as a substitute for, gross profit, operating income, net income, cash and cash equivalents, or cash flows from operations, as measured under 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 balance sheets and statement of cash flows and must be considered in performing a comprehensive assessment of overall financial performance.
