Eastman Chemical Co. insider Adrian James Holt reported a stock ownership change tied to the vesting of a prior equity award, rather than an open-market purchase or sale. On June 1, 2026, Holt received a payout of common stock from restricted stock units originally granted on June 1, 2023. The award covered 4,341 restricted stock units that vested on June 1, 2026, converting into Eastman Chemical common shares under the company’s equity compensation program. As part of the vesting event, Eastman withheld 1,058 shares of common stock to satisfy Holt’s tax withholding obligation. The withheld shares were valued at $75.49 per share. Based on the 4,341 RSUs that vested and the 1,058 shares withheld for taxes, the net shares retained from the vesting would be 3,283 shares, before considering any other holdings or transactions not shown in the text. The filing’s explanatory notes state that the transaction reflects the payout of vested restricted stock units and the related tax withholding. No open-market sale by Holt is described, and the transaction-code labels and post-transaction ownership total are not included in the provided filing text. The Form 4 was signed on Holt’s behalf by Mark D. Austin under power of attorney on June 3, 2026.
