Ronald L. Verkleeren exercised restricted stock units for 2,476 Corning shares. In the same event, 893 shares were disposed of to satisfy tax withholding, leaving him with 34,083 directly owned shares plus multiple unvested RSU awards scheduled to vest between 2026 and 2028.

How many Corning (GLW) shares did the SVP acquire through RSU conversion?

He acquired 2,476 Corning common shares through the exercise and conversion of restricted stock units. The exercise price was recorded as $0 per share, reflecting settlement of RSUs rather than a cash purchase, and increased his directly owned common stock before tax withholding.

Why were 893 Corning (GLW) shares disposed of in this Form 4 filing?

The 893 shares were disposed of to cover tax liabilities tied to the RSU vesting. The transaction used code F, meaning shares were withheld at $131.39 per share for taxes, rather than sold in an open market transaction, reducing his post-transaction holdings to 34,083 shares.

What are Ronald L. Verkleeren’s remaining Corning (GLW) RSU holdings and vesting dates?

He reported three blocks of RSUs: 14,332, 15,333, and 11,612 units. These restricted stock units vest 100% on April 15, 2026, April 15, 2027, and April 14, 2028, respectively, with certain events like retirement or disability potentially accelerating vesting under the award terms.

How many Corning (GLW) common shares does the SVP own after the reported transactions?

After the RSU conversion and tax-withholding disposition, he directly owned 34,083 Corning common shares. This figure reflects the 2,476 shares acquired from RSUs and the 893 shares withheld for taxes, as disclosed in the Form 4 non-derivative securities table.

How do the Corning (GLW) RSUs reported in this Form 4 work?

Each restricted stock unit represents a contingent right to receive one share of Corning common stock. The RSUs vest in full on specified future dates, and certain events like retirement, death, or disability can cause earlier vesting as described in the award agreements’ terms.
