PLAB PHOTRONICS INC Insider Trading

SVP Wang Hsueh-Chun sells 19,250 PLAB shares at $45.30 for $872.0K, reducing stake by 14.5% to 113.6K shares

Wang Hsueh-Chun, SVP/COO of IC & US/EU Mainstream Operations, executed a sale of 19,250 shares at $45.30, reducing his holdings from 132.8K to 113.6K shares. The sale occurred near the 52-week high of $45.86 and follows a 32.2% gain over the prior 30 days. This marks his second open-market transaction at PLAB in five days (prior sell on 2026-04-09), though the recent prior trade outcome remains unmeasurable. At a P/E of 19.84 and market cap of $2.7B, the stock is at historically elevated levels; the fundamental picture shows modest headwinds with annual revenue growth of -2.0% offset by solid earnings of $42.9M on $225.1M in latest quarterly revenue.

Director Macricostas sells entire 50,000 share position in PLAB for $2.3M near 52-week high

MACRICOSTAS CONSTANTINE S, a Director, liquidated his entire holding of 50,000 shares at $45.35 on 2026-04-14, generating $2,267,500.00 in proceeds. The transaction occurred at price levels near the 52-week high of $45.71, with the stock up 36.2% over the prior 30 days and 45.5% over 90 days. Complete elimination of a director's shareholding is a material signal that warrants investor attention, as it represents a full exit from equity ownership in the company. The timing coincides with strong recent price momentum and near-peak valuations, providing context for the decision to exit entirely.

CFO Rivera sold 41,517 shares ($1.8M) at $44.00; holdings fell to 136.2K shares (-23.4%)

Eric Rivera, President and CFO of Photronics, executed 2 separate sales totaling 41,517 shares for $1,826,748.00, reducing his post-transaction holdings from 177.7K to 136.2K shares. The sales occurred at $44.00 per share while the stock currently trades at $45.67, near its 52-week high. The company reported positive fundamentals in its latest quarter ($225.1M revenue, $42.9M net income) with a moderate P/E of 19.77, though annual revenue declined 2.0% year-over-year. The substantial 23.4% reduction in his holdings merits monitoring, though without scheduled trading plan disclosure, transaction timing context is unavailable.

SVP Wang Hsueh-Chun sold 11,875 shares of PLAB at $44.25 on 2026-04-09; holds 132,810 post-sale.

Wang Hsueh-Chun, SVP/COO of IC & US/EU mainstream operations, sold 11,875 shares at $44.25 on 2026-04-09, reducing holdings by 8.2% to 132,810 shares. The sale occurred while PLAB stock trades at $45.67, just 0.0% below its 52-week high of $45.67, following a 36.1% gain over 30 days and 36.8% over 90 days. Against fundamentals showing annual revenue decline of -2.0%, a P/E of 19.77, and a market cap of $2.7B, the timing of a sale by an executive with direct operational responsibility warrants review. No FLAG information is provided; the pattern of discretionary selling near 52-week highs during a sharp recent rally merits investor attention given the company's underlying revenue contraction.

CEO George Macricostas sold 121,194 shares for $5,203,717.60 at blended avg $42.94, reducing holdings 26.6% to 334,068 shares

CEO George Macricostas executed 3 separate sales totaling 121,194 shares for $5,203,717.60 on April 8, 2026, at an average price of $42.94—near the stock's current price of $44.90 and at its 52-week high. The transaction represents a material 26.6% reduction in his post-transaction holdings to 334,068 shares from 455,262 shares, a significant concentration reduction for the company's chief executive. This occurs in a context of strong near-term momentum (30-day change: +30.6%; 90-day change: +34.7%), though the company faces longer-term headwinds with annual revenue declining 2.0%. The scale of the sale and timing relative to the stock's recent strength warrants investor scrutiny regarding executive confidence in valuation.

EVP/CTO Progler sells 25,000 PLAB shares at $35.78; prior 5 sales at this ticker all well-timed (90d losses -13.6% to -13.9%)

Christopher J. Progler, EVP and Chief Technology Officer, executed a sale of 25,000 shares at $35.78 on 2025-12-12, reducing his holdings by 13.1% to 165.6K shares and generating $894.5K in proceeds. Notably, his prior trades at PLAB establish a compelling timing pattern: all five prior sales on 2024-12-19 were well-timed, with subsequent 90-day returns ranging from -13.6% to -13.9%, indicating he consistently sold ahead of downturns. His cross-ticker track record reinforces this with a 100.00% well-timed rate on six prior sells, suggesting an established pattern of selling discipline. The stock has since declined from the $35.78 transaction price to $34.36 (current), sitting -13.4% from its 52-week high, though recent momentum shows +62.7% over 30 days and +46.8% over 90 days. This sale merits investor scrutiny as part of a demonstrated insider track record of well-timed equity exits at this issuer.

Director Mary Paladino sold 42,750 shares of PLAB at $24.00 on 2025-10-02, reducing holdings by 55.8%.

Mary Paladino, a director at Photronics Inc (PLAB), sold 42,750 shares at $24.00 on 2025-10-02, reducing her holdings from 76,548 shares to 33,798 shares—a substantial 55.8% reduction of her pre-transaction position. The sale occurred at a price $1.05 below the current market price of $25.05, and below the 52-week high of $28.06, suggesting the sale was not executed at peak valuation. The company trades at a P/E of 11.82 with modest positive net income of $22.9M on revenue of $210.4M, though annual revenue has declined 2.8% year-over-year. The sale represents a material reduction in insider ownership without additional context on timing constraints or portfolio considerations.

PLAB director Garcia purchases 2,650 shares at $19.00, raising stake 35.1% to 10,198 shares

Director Garcia David A. purchased 2,650 shares of Photronics Inc at $19.00 on 2025-06-27, increasing his holdings from 7,548 to 10,198 shares—a 35.1% increase in position size. The transaction occurred when the stock was trading at $19.00, which is -32.9% below the 52-week high of $28.06 but sits within a year-long trading range. The company trades at a P/E of 8.88 with recent quarterly revenue of $210,992,000.00 and annual revenue growth of -2.8%, reflecting a mature, modestly profitable enterprise. This open-market purchase by a director warrants observation as an insider action, though the modest absolute share count and relatively small position within the $1.1B market cap limit its immediate signaling strength.

Photronics CEO Lee Kang Jyh sold 20,000 shares for $505,400.00 at blended average $25.27 on 2024-12-19

CEO Lee Kang Jyh executed 2 separate sales totaling 20,000 shares for $505,400.00 on December 19, 2024, at an average price of $25.27 per share. Post-transaction, he retains 554,600 shares, representing a -3.5% reduction from prior holdings of 574,600 shares. The sales occurred when the stock traded around $25.25–$25.29, compared to the current price of $24.04, placing the transaction at a premium to present levels. The company's fundamentals show stable profitability with net income of $34,388,000.00 on revenue of $210,984,000.00 in the latest quarter, though annual revenue has contracted -2.8% year-over-year, and the stock trades at a modest P/E of 10.36. The transaction's modest scale relative to his substantial remaining position offers limited insight into directional conviction.

CTO Progler sells 63,000 PLAB shares for $1.6M; post-sale holding 219.2K shares; stock -29.0% from 52-week high.

Christopher J. Progler, EVP and Chief Technology Officer, executed 6 separate sales totaling 63,000 shares for $1,565,523.12 on December 19, 2024, at an average price of $24.85 per share. His remaining position is 219.2K shares, representing a -22.3% reduction from his prior 282.2K shares. The sale occurred when PLAB stock trades at $24.04, down 29.0% from its 52-week high of $33.84, suggesting the CTO divested a material portion of his stake during a period of notable price depreciation. With the company reporting a 10.36 P/E and annual revenue growth of -2.8%, the magnitude and timing of this reduction merit observation of whether it reflects broader confidence levels within senior technology leadership.
