GLW CORNING INC /NY Insider Trading

SVP & Chief Tech Officer Jaymin Amin sold 27,395 shares of GLW at $192.14 for $5,263,636.95 on 2026-05-22

Jaymin Amin, SVP and Chief Technology Officer, sold 27,395 shares (27.4K shares) at $192.14, reducing his non-derivative holdings from 121,795 to 94,400 shares (-22.5%). The sale occurred at a price within the 52-week range, specifically 7.4% below the 52-week high of $211.79. His prior sale at GLW on 2025-09-17 posted a 90-day return of +11.8%, indicating the stock rose after that sale—a pattern inconsistent with prescient sell timing. The company reports strong fundamentals with $4.1B quarterly revenue and annual growth of +19.1%, though the P/E of 93.41 reflects elevated valuation expectations. The form 4 shows this represents a partial reduction in his shareholding, with derivative holdings now at 0 shares remaining.

GLW EVP/COO Nelson Avery H Iii sold 20,000 shares at $195.93 on 2026-05-15 for $3,918,600.00, leaving 70,059 shares. Current price $178.59.

Nelson Avery H Iii sold 20,000 shares for $3,918,600.00 at $195.93, reducing his stake from 90,059 to 70,059 shares. The transaction occurred when GLW was trading near its 52-week high of $211.79, though current price is $178.59, down -15.7% from that peak. His two prior sales at GLW on 2026-02-09 and 2025-07-30 were followed by positive 90-day returns of +44.0% and +38.8% respectively, indicating those sales preceded gains rather than declines. The current sale occurs against a backdrop of strong recent momentum (90-day change: +36.8%) and solid fundamentals (annual revenue growth +19.1%, net income $371.0M on $4.1B quarterly revenue), though the P/E of 85.04 reflects a premium valuation.

SVP Ronald L Verkleeren sells 10,000 GLW shares at $207.77; retains 48,143 shares post-transaction

Ronald L Verkleeren, SVP of Emerging Innovations Group, executed a $2.1M sale of Corning shares at $207.77, near the 52-week high of $211.79 (off by -1.6%), with the stock up +20.6% over 30 days and +56.1% over 90 days. His track record on prior sells shows mixed timing—averaging -3.9% return over 30 days but +43.6% over 90 days, with a 0.00% well-timed rate suggesting his sell-offs have not consistently preceded downturns. The executive maintains substantial holdings of 48.1K shares post-transaction, indicating continued material stake in the company despite the sale. At a P/E of 99.22 and annual revenue growth of +19.1%, the stock commands a rich valuation; the well-timed execution near the 52-week high, combined with strong recent momentum and elevated multiples, suggests tactical profit-taking rather than a crisis signal.

SVP & General Counsel Michaune D Tillman sold 3,260 shares (24.3% of holdings) as GLW trades at 52-week high.

Michaune D Tillman, SVP and General Counsel of Corning, sold approximately one-quarter of her shareholding on a date when the stock was trading at its 52-week high following a sharp rally. This is her first open-market sale in the past three years, a notable shift from a prior activity pattern centered on stock-based compensation transactions. The timing—selling into strength after the stock has climbed substantially over the prior quarter—is a textbook risk-reduction move common among executives. That said, Corning remains a profitable, growing company, so the sale does not signal fundamental distress; rather, it reflects a deliberate reduction of concentrated exposure at a favorable price point. Investors should monitor whether other insiders follow suit, but this single trade is insufficient to suggest operational concerns.

Senior VP & CDIO Seetharam Soumya sells 20,000 GLW shares; stock near 52-week high after strong rally; insider's prior exits showed mixed near-term timing.

Seetharam Soumya, Senior Vice President and Chief Digital & Innovation Officer at Corning, sold a significant stake of roughly 44 percent of his holdings as the stock trades near its 52-week high following a strong multi-month rally. This is his fifth open-market sale in the past three years, continuing a pattern of regular dispositions rather than open-market purchases. His prior two sales at this ticker showed conflicting outcomes: one preceded a stock decline over the following months, while the other was followed by a substantial gain, suggesting his timing at this company has been mixed. The company remains profitable with growing revenue, but the stock's extended valuation and the insider's repeated sales in a rising market may reflect a view that current prices offer an exit opportunity for a portion of his stake.

Exec VP and CCDO John Z. Zhang sells 10,000 GLW shares (66% of holdings) for ~$2M as stock rallies sharply in short timeframe.

John Z. Zhang, serving as Executive Vice President and Chief Commercial and Development Officer, executed a substantial sale of shares comprising roughly two-thirds of his holdings. The timing is notable: the sale occurred when the stock was trading at its 52-week high, following a significant rally over both the prior month and prior quarter. Zhang's 3-year Form 4 history shows a consistent pattern of open-market selling—this is his 11th open-market sale in the 36-month window, with no open-market purchases recorded during that period. The company itself is financially healthy and profitable with growing revenues, providing no obvious operational distress that would necessitate executive liquidation. The combination of heavy insider selling at peak valuations, a sustained pattern of dispositions over years without offsetting purchases, and the stock's elevated price position relative to recent ranges suggests Zhang may be trimming exposure after significant recent gains.

Vice Chairman Lewis Steverson divests nearly half his Corning stake in largest sale; mixed timing history on prior exits.

Lewis Steverson, Vice Chairman and Chief Legal and Administrative Officer, sold approximately half his Corning holdings in a single transaction worth over $5.4 million, marking his fourth open-market sale in three years. The stock is trading at its 52-week highs and has rallied sharply over recent months, a backdrop that could explain the timing of this divestiture. His prior three sales at Corning tell a mixed story: one resulted in the stock declining afterward (well-timed), while the other two saw shares rise in the periods following his exits, suggesting inconsistent timing judgment. The company itself remains profitable and revenue-growing, but the divestiture of this scale by a senior officer reduces his personal stake materially and stands out as a significant reduction in executive alignment with shareholder interests.

Senior VP & CHRO Michelle Gullo sells ~1M in GLW shares; stock near 52-week highs after sharp rally

Michelle Gullo, Corning's Senior Vice President and Chief Human Resources Officer, sold roughly 1 million dollars worth of company shares on a single trading day. The sale represents a meaningful portfolio reduction—roughly one-eighth of her holdings. The timing is notable: Corning's stock has rallied sharply and now trades at its 52-week highs after a sustained climb, and Gullo's sale occurred precisely at that peak. From a company perspective, Corning is financially healthy—profitable with growing revenue—and trades on a stretched valuation multiple. Gullo's prior three years of Form 4 activity show she has sold shares on the open market multiple times before, so this is not her first disposition, but the size and price point distinguish it from routine executive activity. The sale of company shares by a sitting C-suite executive at an inflated stock price in a financially sound company is material enough for investors to monitor, though the data available does not explain her rationale.

SVP Finance Stefan Becker sells 21,000 Corning shares for $3.9M; stock at all-time highs after sharp rally

Stefan Becker, SVP of Finance and Corporate Controller, sold over 21,000 shares—representing most of his holdings—as Corning trades at its all-time high after a dramatic rally. This is his fifth open-market sale of Corning stock in roughly eighteen months. His prior four exits from this stock show conflicting timing signals: over a thirty-day window, one was well-timed as the stock dipped, but three saw subsequent gains; over a ninety-day window, all four prior sales were poorly-timed as the stock recovered and climbed significantly. The current sale occurs as the company is profitable with strong revenue growth, trading at a stretched valuation multiple, which may explain why a finance officer is lightening his position at peak prices. The pattern of persistent selling at or near highs—combined with poor long-term timing on his prior Corning exits—suggests this officer is managing concentration risk rather than signaling confidence in the stock's near-term direction.

CFO Edward Schlesinger sells 22,562 shares (~26% of stake) at Corning, crossing $4.2M threshold as stock reaches 52-week highs.

Edward Schlesinger, Corning's CFO, sold more than one-quarter of his holdings as the stock trades at its highest price in the past year and the company reports strong revenue growth with profitable operations. This is Schlesinger's fifth sale in the stock over the past eight months, adding to a pattern of consistent selling. His three most recent prior sales in this stock produced mixed results: two saw the stock rise afterward (poorly timed exits), while one saw the stock decline afterward (well-timed exit). The company's fundamentals remain solid—profitable with expanding revenue—but Schlesinger's choice to exit a significant portion of his stake while shares are elevated deserves attention alongside his historical track record of mostly poorly-timed sales in this same security.
