Wärtsilä’s own chief financial officer has pointed to a specific accounting rule change as a reason the new 50:50 joint venture with RCT Solutions matters for how the company’s results will look going forward. Under IFRS 18, effective January 1, 2027, the venture’s results will move out of Wärtsilä’s operating result and into a separate investing activities line, removing a loss-making business from the metric investors use most to judge the company’s core performance, just as the venture’s own forecast shows it finally turning profitable.
The joint venture, named Valo, formally closed on October 1 after a transaction first announced in June, following an 18-month strategic review of the energy storage business that Wärtsilä’s leadership initiated in October 2023. That review’s eventual outcome, a 50:50 structure rather than an outright sale, is itself informative: Wärtsilä’s own executives have said they remain in discussions with additional parties about further investment in the venture, an arrangement that would dilute both Wärtsilä’s and RCT Solutions’ initial stakes, language more consistent with a transitional structure awaiting a fuller exit than with a settled long-term ownership arrangement either party intends to hold indefinitely.
The immediate financial cost of the transition is specific and already booked. Wärtsilä has quantified a 40 million to 50 million euro hit to its 2026 operating result tied to establishing the joint venture, and separately recognized a write-down of capitalized research and development related to the energy storage business on its own balance sheet before the transaction closed, rather than transferring that cost into the new entity as the companies had previously said would happen. That change in treatment means Wärtsilä’s existing shareholders absorb the full R&D write-down rather than splitting it with RCT Solutions through the 50:50 ownership structure, a detail that shifts cost exposure away from the new joint venture at the same time the venture is being positioned as a shared platform for growth. The business being transferred, 694 million euros in 2025 net sales and a headcount that moved from roughly 480 people at the June announcement to about 450 by the October close, is Wärtsilä’s smallest reporting segment, one the company has said faces persistent profitability challenges, weak demand and limited synergies with its core marine and energy generation businesses.
The accounting timeline disclosed around the deal adds a further dimension to how the structure should be read. CFO Arjen Berends has said that once IFRS 18 takes effect on January 1, 2027, the joint venture’s financial results will no longer appear within Wärtsilä’s operating result at all, shifting instead into a separate line for results from investing activities. That change arrives just as the venture’s own forecast trajectory shows it moving from an operating loss in 2026 to expected positive results toward the end of 2027, meaning Wärtsilä’s current operating profit metric will absorb the business during almost exactly the period it is still losing money, before a new reporting classification removes it from that same metric right as performance is projected to turn around. Whether that timing reflects a coincidence of accounting standard adoption or a structure chosen partly because of it, the practical effect is that Wärtsilä’s headline operating results will carry the business’s losses but not its anticipated recovery.
RCT Solutions brings a narrower base to the arrangement than a 50:50 ownership split might suggest on its own. The Konstanz, Germany-based firm is a specialized solar and storage engineering manufacturer, and an RCT-affiliated company had already served as a supplier to Wärtsilä’s energy storage business for several years before this transaction, meaning the joint venture formalizes and deepens an existing commercial relationship rather than introducing an entirely new outside partner with independent scale.
RCT’s stated ambition of becoming a vertically integrated global battery storage player is considerably larger than what the company’s current position as a specialized German supplier would suggest it can fund on its own, consistent with both companies’ acknowledgment that outside investment will likely be needed to carry the venture forward. Taken together, the pre-transaction write-down kept off the joint venture’s books, an accounting rule change timed closely with the venture’s projected path to profitability, and an explicitly anticipated need for future dilution describe a transaction managing Wärtsilä’s financial exposure and reporting optics at least as much as it describes the growth platform the announcement’s own language emphasizes.
