FREYR Battery Provides Operations Update

FREYR Battery (NYSE: FREY) ("FREYR" or the "Company"), a developer of clean, next-generation battery cell production capacity, has provided an update this morning on the company's operational progress at the Customer Qualification Plant ("CQP") in Mo i Rana, Norway.

Successful automated cathode casting trials

Following successful adjustments to the cathode casting equipment that included updates to the vacuum system, last week, FREYR's teams at the CQP commenced automated cathode casting runs at a minimum nozzle distance of 0.26 mm.

The CQP teams have subsequently conducted successful cathode casting runs using the cathode web and solvent slurry at fixed nozzle distances of 0.5 mm and 1.0 mm, respectively, and at speeds of 2 meters per minute while using 100 psi of casting pressure. These successful automated cathode casting runs with solvent slurry were an important precursor to completing the Casting and Unit Cell Assembly commissioning packages and the eventual start of automated CQP production.

"I am very pleased to share that our teams at the CQP have reached another important interim technical milestone," commented Mike Brose, FREYR's Head of the Asset Mo team. "In doing so, our people and partners have demonstrated their collective ability to systematically link small but critical steps together to achieve the required outcome. We are able to integrate this vital part of the SemiSolid^TM technology platform only because of the many milestones already completed together over the last several months by the FREYR Asset Mo team, our coworkers around the world, and our valued partners and suppliers. As we look forward to 2024, FREYR's top priority is to finalize commissioning at the CQP and to begin automated production of in-spec, customer-testable batteries. With this latest milestone behind us, we will continue to apply unwavering focus to the remaining tasks that are necessary to achieve that goal."

CQP commissioning status and key next steps

Following the successful automated cathode casting trials, FREYR has completed handovers of 342 (88%) of the 388 discrete production line equipment commissioning and testing packages at the CQP. The test center packages and handovers to operations are all complete.

The next technical requirements to stay on track with FREYR's anticipated completion cadence at the CQP are:

• Replicate the successful automated cathode casting trials with the anode production line system; and
• Integrate the casting webs across the cathode, anode, and merge units of the Casting and Unit Cell Assembly equipment using the highly complex Multi-Carrier Systems ("MCS") to reach automated cell production.
