A landmark 2 MW order for our M2Power 250 systems worth over 150 MSEK from a major European shipbuilder marked a strong start to the ye ar and is an important step forward in our transition toward an OEM-driven business model. This order is not just a commercial success, it shows that our marine offering is meeting the needs of customers moving from pilot projects to real operations. Fuel cell systems are increasingly becoming part of long -term propulsion and power generation plans in active fl eets, particularly within cruise ships and large yachts. While policy and regulatory signals remain mixed, demand continues at a steady pace. More of our customers now come to us with clear industrialization plans, structured procurement processes, and a readiness to scale, although decision cycles are being slo wed by broader global uncertainty. Solid First Quarter Performance with Continued Focus on Long-Term Fundamentals The order also confirms our growth strategy: increase the number of installations - and increase PowerCell’s value per installation. The M2Power 250 supports both. It’s encouraging to see yet another new product gaining traction so soon after launch. With the M2Power 250, we are taking PowerCell beyond fuel cell electrification, simplifying integration for shipyards and system integrators, and accelerating hydrogen adoption in markets where infrastructure is still catching up. In the first quarter, net sales amounted to SEK 74 million, representing a 42% increase compared to the same period last year. The growth is primarily driven by increased OEM deliveries, which now account for a growing share of our overall business. EBITDA improved to SEK -6 million, compared to SEK -24 million in the first quarter of 2024, reflecting improved leverage and continued cost discipline. Gross margins remained stable, supported by a better product mix and growing contributions from application development and services. Operating cash flow for the quarter was SEK -79 million. The decline is primarily due to periodization of significant procurements in Q4 2024 attached to project deliveries with customer invoice milestones during H1 2025. Q1 also marks the third consecutive quarter with monthly OEM -related product order intake exceeding SEK 50 million, an important signal of both consistency and scale in our core business. Investing in Capability and Scaling for Long-Term Delivery We continue to strengthen our industrial foundation to support growing OEM demand. In the quarter, we were awarded AS9100 certification, confirming our quality management systems meet the rigorous standards of the aviation industry. Production of the Marine System 225 is scaling up to meet increasing volumes from OEM customers, and we have expanded our capacity for customer commissioning. These steps are key as more deliveries move from pilots to full - scale commercial use. From Innovation to Integration The theme of this quarter is steady progress. As the green energy transition continues, we see mixed policy signals and financial pressure across parts of the industry. It’s a complex environment, but real transformation is rarely about perfect conditions. It’s about moving forward ev en when things aren’t fully settled. At PowerCell, we’re focused on integration. Innovation isn’t just about introducing new technology, it’s about making sure it works in the hands of real customers, in real operations. That’s where the Marine System 225 and M2Power 250 come in. These platfo rms are designed to meet industrial requirements in lab settings, shipyards, docks, and day-to-day maritime operations. We're now delivering systems that plug into our customers’ existing workflows and long -term plans. That’s how we support the transition, not just by developing new solutions, but by making sure they’re usable, scalable, and aligned with where the market is heading. We’re seeing early signals of this shift across the board: demand from more mature customers, product adoption tied to real operational plans, and technology that is moving from demonstration to deployment. Gothenburg, March 2025 CEO Richard Berkling ===== SIDA 4 ===== Interim report first quarter 2025 4 Financial performance January-March 2025 Net sales Net sales amounted to SEK 74.1m (52.1), an increase of 42%. The Marine segment contributes by SEK 43.5m to the quarterly net sales. Sales of projects, according to percentage of completion, amounted to SEK 41.5m (27.9). Royalty fees from Robert Bosch GmbH accounted to SEK 5.0m (2.8). Gross profit and operating income/loss Gross profit increased to SEK 27.5m (24.6) with a gross margin of 37.1% (47.2), however margin was held back by negative currency effects EUR/SEK, approximately SEK 18m, following re-evaluating project reported as percentage of completion. During first quarter 2024 gross margin was impacted positively by currency effects of approximately SEK 8m. Other operating income amounted to SEK 24.1m (6.9). The difference compared to previous year predominantly caused by more projects subject for grants. In the quarter, SEK 10.5m (9.5) was capitalised as development expenditures. The majority of the capitalised expenditures are related to the development of a new version of PS200 system. Net income and financial items Net financial items amounted to SEK -4.5m (4.1). Net income in the quarter was SEK -15.7m (-25.1). Cash flow During the quarter operating cash flow was SEK -79.3m (38.7). The negative operating cash flow is predominantly related to significant changes in accounts receivable and accounts payable totalling approximately SEK -79m impacting operating cash flow negatively. This situation is deriving from large pre-buys for projects during Q4 and milestones for invoicing in customer project plans during Q1, not yet collected. The rollover effect between quarters was expected and mentioned in the Q4 presentation. Cash flow from investing activities was affected by product development capitalisation. In the quarter, SEK 10.5m (9.5) was capitalised as intangible assets. Total cash flow for the quarter amounts to SEK -92.1m (26.5).

Gross margin may help investors understand how much revenue the company retains, which can be used to pay other costs. Net sales rolling twelve-month Net sales for a period that is determined monthly and consists of the previous twelve consecutive calendar months. Net sales rolling twelve months can give investors an understanding of the company’s sales development on a more current basis than the previous financial year. ===== SIDA 14 ===== Interim report first quarter 2025 14 Other information Employees On March 31, 2025, the Group had 146 (149) employees measured as full-time equivalents, FTE.
