Photocure ASA: Update on milestone payments from Asieris Pharmaceuticals

Oslo, Norway, April 20, 2026 - Reference is made to Photocure ASA's (OSE: PHO)
announcement dated 3 March 2026, in which the Company 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
enables 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 has in accordance with its license agreement with Asieris invoiced the
applicable milestone payment of $11M USD. Asieris has made a partial payment of
$6.6M USD. Asieris has indicated that the partial payment reflects its position
that the approved label obtained for Cevira in China is insufficient to trigger
the full milestone amount.

While Photocure seeks to maintain constructive dialogue with Asieris, the
Company believes that Asieris' position is without merit and the milestone
trigger is met. Photocure will assess all available measures and take all
appropriate actions to pursue full payment by Asieris in accordance with the
license agreement.
