Operational Update - Q2 2026

Bodø, Norway, 3 July 2026 – Gigante Salmon AS (OSE: GIGA) today announces an operational update for the second quarter of 2026:

Key operational highlights Harvested volume in the quarter was 653 tonnes HOG. Harvested fish achieved an average weight of 2.95 kg HOG, with 72% superior quality and an economic feed conversion ratio (eFCR) of 1.31. The realised sales price was NOK 62.4 per kg HOG. At quarter-end, the Company had an estimated standing biomass of 2,500 tonnes with an average weight of 1.22 kg. The biomass consists solely of the H2025 generation and is scheduled for harvest between the fourth quarter of 2026 and the second quarter of 2027. Based on the final harvest of the H2024 generation, the Company now expects total cost of production for 2026 to be approximately NOK 81 per kg HOG. Financial expenses account for slightly above NOK 13 per kg HOG. Cost of production excluding financial expenses is somewhat higher than previously anticipated but remains, in all material respects, in line with the Company's earlier expectations.

Regulatory dialogue The Company remains engaged in ongoing discussions with the Norwegian Food Safety Authority (Mattilsynet) regarding fish survival, fish welfare and environmental conditions in the production tanks, and with the County Governor (Statsforvalteren) regarding sludge management, treatment and marine discharge. The Norwegian Food Safety Authority has communicated an increased regulatory focus on these matters.

Investment activity During the quarter, the Company invested approximately NOK 60 million in its production facility. The investments primarily relate to increased capacity in the feeding and oxygenation systems, residential facilities, and the implementation of new technology for sludge collection and handling, including modifications to the production tanks. These modifications have reduced available tank volume by approximately 5%. The Company is evaluating measures to offset this reduction, including increasing water levels in the tanks. The investments are expected to strengthen operational robustness, improve environmental conditions within the production system, enhance fish welfare and facilitate efficient sludge collection and treatment.

Production plan and financing The Company expects to stock approximately 3 million smolt during late summer and autumn 2026. To support continued operations and planned production growth, the available overdraft facility with SpareBank 1 Nord-Norge was increased during the quarter from NOK 140 million to NOK 240 million.

The full Q2 2026 report will be published on 18 August 2026 at 07:00 CEST and will be available at www.gigantesalmon.no and www.newsweb.no.
