Eric S. Musser, President and COO of Corning Incorporated (GLW), has been a consistent seller of company stock over the past year, with no open-market purchases recorded across his 46 total Form 4 filings. The aggregate value of his sales reached approximately $19.2 million, all concentrated in GLW, while his only other company affiliation, Wolfspeed (WOLF), appears solely in a December 2025 grant with no transaction value. The most recent activity, on February 9, 2026, shows a $1.95 million open-market sale, following a $2.75 million sale on February 2 and a $9.0 million sale on October 29, 2025—the largest single transaction in the dataset. These sales are interspersed with routine compensation events: zero-value grants (code A), option exercises (code M), and shares withheld for tax obligations (code F), which are mechanical and not discretionary. The pattern reveals a clear sell-side bias, with six open-market sales (code S) in the last six months and no corresponding purchases. Beyond the three largest sales, Musser executed smaller dispositions on September 4, 2025 ($1.4 million), August 11, 2025 ($1.23 million), and August 7, 2025 ($1.32 million), all in GLW. The February 4, 2026 filing bundled three grants, three option exercises, and a $360,222 tax-withholding transaction, typical of a vesting event. Notably, the August 11, 2025 sale was paired with a $370,403 option exercise, suggesting the sale was partly to cover exercise costs, but the sheer frequency and size of the open-market sales—averaging over $3 million per disposition—indicate a deliberate, ongoing reduction of his GLW stake. No buys (code P) appear anywhere in the record, reinforcing a one-directional flow of shares out of insider hands.
