Photronics Reports First Quarter Fiscal 2024 Results

BROOKFIELD, Conn. February 21, 2024 (GLOBE NEWSWIRE) — Photronics, Inc. (NASDAQ:PLAB), a worldwide leader in photomask technologies and solutions, today reported financial results for its first quarter of fiscal year 2024 ended January 28, 2024.

“First quarter revenue increased year-over-year even though typically lower seasonal demand was weaker than anticipated, especially in the beginning of the quarter. Order rates improved through the quarter, continuing into second quarter.” said Frank Lee, chief executive officer. “High-end IC revenue increased both sequentially and year-over-year, primarily in 22nm and 28nm nodes, as customers continue migration to these nodes for improved performance and optimal cost. High-end FPD also increased over last year’s first quarter, but decreased from the fourth quarter due to typically lower seasonal demand for premium smartphone displays that use AMOLED technology. Operating margin increased year-over-year, but contracted sequentially, resulting from operating leverage in the year-over-year result and the impact of higher operating expenses in the sequential comparison. Cash generation remains strong, further strengthening our balance sheet with ample liquidity for our profitable growth investments. The Photronics team continues their outstanding performance, and with expectations for growth in the second quarter, we are building momentum for another record year in 2024.”

Non-GAAP Financial Measures

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