Second Quarter 2025 Business Update

Highlights

• On track toward IND/CTA submission in 2H 2025 and first-in-human trial initiation in 1H 2026.
• Broadened regulatory engagement: following positive FDA pre-IND feedback (Q2 2024), submitted a scientific advice briefing package to the UK MHRA in July 2025 for ZI-MA4-1.
• Initiated GMP manufacturing of clinical material in July 2025, a major step in clinical readiness; scalable platform developed with Catalent can deliver hundreds of doses from a single batch.
• Strong support from leading clinical experts and sites; refined trial design and moving to operational readiness ahead of IND/CTA submission

Financial highlights

• Total operating expenses amounted to MNOK 38.4 in Q2 2025, and MNOK 67.8 YTD. Total loss was MNOK 37.5 for the period and MNOK 66.0 YTD.
• Net negative cash flow from operations was MNOK 59.4 in Q2 2025, and net decrease in cash and cash equivalents, excluding currency effects, was MNOK 59.0 during Q2 2025. Cash and cash equivalents amounted to MNOK 76.0 as per 30 June 2025.
• The current cash is expected to give a financial runway into Q2 2026, slightly shortened from the previously guided ‘through Q2 2026’ due to some one-off cost elements mainly related to investment in the successful development of the TCR-NK manufacturing process. The expected financial runway reflects that the cash burn rate is forecasted to come down significantly from the Q2 2025 level.
• On 27 May 2025, Zelluna ASA issued 227,096 new shares, each with a subscription price of NOK 26, to settle an amount of EUR 500,000 of an already triggered option exercise fee towards Inven2.

The quarterly report and presentation will be published at 07:00 CET on 20 August 2025, and will be publicly available on the Zelluna website. The Company will conduct a webcast at 09:00 CET the same day, and questions can be submitted throughout the event. The webcast will be archived for replay following the conference call.
