Otsuka: Ends buyback, to cancel 4.54m shares, or 0.84%

Otsuka completed its share buyback by Oct. 28, spending nearly the full amount authorized, though the number of shares acquired fell short of the cap.

The buyback ran from Feb. 16 to Oct. 28, 2026, through market purchases on the Tokyo Stock Exchange. It was conducted under a board resolution dated Feb. 13, 2026. With spending close to the authorized ceiling, Otsuka used nearly all of the approved amount.

Otsuka will cancel all of the shares it acquired. They represent 0.84% of shares outstanding before the cancellation, leaving 538,451,217 shares outstanding afterward.

• Shares to be canceled: All ordinary shares acquired in the buyback

Canceling treasury shares removes them from the share count. The move does not change profit itself, but, all else being equal, it may affect earnings per share and shareholders’ ownership stakes. Investors should distinguish the cash spent on the buyback from the change in the number of shares following cancellation.
