(PLAB) Investigation:Photronics is a leading manufacturer of photomasks, high-precision photographic quartz or glass plates containing microscopic images of electronic circuits. Photomasks are a key element of integrated circuits (&#34;ICs&#34;) and flat panel displays (&#34;FPDs&#34;). IC sales comprise the bulk of Photronics' total revenues.On December 10, 2025, Photronics revealed an unusual accounting move during its QE and FYE October 31, 2025 earnings call. The company recognized a tax valuation allowance reversal which it said &#34;reflect[ed] an improvement in our US execution and outlook[.]&#34; CFO Eric Rivera explained that the valuation allowance had originally been recorded because &#34;the benefit was previously deemed unrealizable[,]&#34; but &#34;[g] iven the improved performance and outlook of our US business, US GAAP required a reversal of this tax loss allowance, resulting in the positive $16.8 million result to GAAP net income.&#34;The accounting maneuver's effect significantly bolstered the company's non-GAAP EPS (after reconciling the reversal) up about 17.6%. The market positively reacted to the reversal, sending the price of the company shares up $11.66 (+45%) that day.Investors' expectations for improving performance were dashed on May 28, 2026.That day, Photronics' operational reality became apparent when the company reported dismal financial results for its Q2 2026. Among the areas of concern were sequential declines in revenues (-6.7%), IC revenues (-11%), operating margins (-17.6%), GAAP net income (-26.8%), and non-GAAP net income (-30%).In response, the market sent the price of Photronics shares down 36%, wiping out over $1.1 billion of the company's market capitalization in a single day.Adding a psychological weight to the stock's narrative, SEC filings have revealed that company insiders sold off more than $15 million worth of shares over the trailing three months leading up to this report.&#34;Our investigation is focused on whether Photronics may have misled investors about the propriety of reversing the allowance that it previously deemed unrealizable,&#34; said Reed Kathrein, the Hagens Berman partner leading the firm's investigation.If you invested in Photronics and have substantial losses, or have knowledge that will assist the firm's investigation, submit your losses now »If you'd like more information and answers to other frequently asked questions about the firm's Verra investigation, read more »Whistleblowers: Persons with non-public information regarding Photronics should consider their options to help in the investigation or take advantage of the SEC Whistleblower program.
