Photocure ASA: Asieris counterclaim on milestone payment arbitration

Oslo, Norway, August 4, 2026 - Reference is made to Photocure ASA's (OSE: PHO) announcement dated 3 March 2026, in which Photocure noted that its partner, Asieris Pharmaceuticals (SSE: 688176), had announced receipt of the Drug Registration Certificate from China's National Medical Products Administration (NMPA) for its core product APL-1702 (trade name: CEVIRA[®]). This approval enabled commercial launch in China. Photocure further confirmed in this announcement that with Cevira's regulatory approval in China it is entitled to a milestone payment.

Photocure had in accordance with its license agreement with Asieris invoiced the applicable milestone payment of $11M USD. As communicated in a stock exchange announcement on 20 April, 2026, Asieris made a partial payment of $6.6M USD and indicated that the partial payment reflected its position that the approved label obtained for Cevira in China is insufficient to trigger the full milestone amount. On 23 July, 2026 Photocure announced that it had commenced arbitration in the partial payment case with Asieris. Separately, Asieris had communicated receipt of the arbitration demand and supporting documents filed by Photocure.

On 3 August, 2026 after close of trading, Asieris filed its response to Photocure's arbitration demand in which it denied Photocure's claim to the full milestone payment of $11M USD. Asieris also filed a counterclaim in which it alleged that the milestone payment has not been triggered and seeks the return of the $6.6M USD.

Photocure maintains that the milestone has been achieved and will vigorously pursue full payment by Asieris in accordance with the license agreement.
