Corning exec sells $2M in shares amid record stock surge and high insider activity
Corning’s senior vice president, Ronald Verkleeren, sold 10,000 shares of the company on May 13, 2026. The transaction amounted to over $2 million, with shares trading at $207.77 each. This sale comes amid a year of strong stock performance and high insider selling activity at the firm. The sale took place as Corning’s stock price climbed by 0.86% on the same day. Year-to-date, the company’s shares had surged by 136.28%, pushing its market capitalisation to around $179 billion. Despite this growth, insiders have shown a clear trend: Verkleeren alone sold 51,000 shares over the past year without making any purchases.
Corning’s first-quarter results highlighted double-digit revenue and earnings-per-share growth. Margins also expanded, supported by major deals with hyperscalers and solar sector clients. Yet, the stock’s valuation remains high, with a P/E ratio of 99.66—far above the industry median of 32.3. GuruFocus estimates the company’s intrinsic value at $59.25 per share, giving it a price-to-GF-Value ratio of 3.51. After this latest transaction, Verkleeren still holds 48,143 shares in Corning.
The sale adds to a pattern of 45 insider disposals and no buys at Corning over the last 12 months. Verkleeren’s remaining stake stands at 48,143 shares, while the company’s stock continues to trade well above its estimated intrinsic value. Analysts and investors will likely watch for further insider activity in the coming months.
