Form 4 Filing for Eastman Chemical Co.

This filing details a transaction by James J. O'Brien, a director at Eastman Chemical Co. On April 8, 2026, 408 Phantom Stock Units were credited under the Directors' Deferred Compensation Plan. These units, each valued at one share of the company's common stock, will be paid in cash after O'Brien ceases to be a director. The transaction code 'A' indicates acquisition, and the units were acquired automatically as a deferral of cash retainer fees. Dividend equivalents were reinvested, increasing the number of units. The transaction resulted in 18,137 units held post-transaction. The exercise price and transaction price were both reported as zero, with footnotes clarifying the nature of the units and the reinvestment of dividends.
