Photronics Reports Third Quarter Fiscal 2024 Results

and Share Repurchase Authorization

BROOKFIELD, Conn. August 29, 2024 (GLOBE NEWSWIRE) — Photronics, Inc. (NASDAQ:PLAB), a worldwide leader in photomask technologies and solutions, today reported financial results for its third quarter of fiscal year 2024 ended July 28, 2024.

“Market softness in some segments during the quarter impacted photomask demand, reducing both IC and FPD revenue,” said Frank Lee, chief executive officer. “The photomask demand recovery that started to take shape early in the third quarter slowed during the period due to select regional and end-use customer order patterns. This was combined with broader customer focus on rising semiconductor channel inventory that limited chip design activity through the quarter. In response, we tuned our mix and sales strategy, allowing us to optimize margins despite lower demand. Megatrends such as AI, supply chain regionalization, and edge computing are driving secular photomask value and demand, supporting our optimistic view of the long-term global photomask industry outlook. Our leadership position gives us confidence we can drive future margins while at the same time execute smart investment and deployment strategies that can deliver top line growth and shareholder value.”

Non-GAAP Financial Measures

Non-GAAP Net Income attributable to Photronics, Inc. shareholders and non-GAAP earnings per share 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 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 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.
