Fortum Oyj shares experienced a dramatic 13.6% surge on Wednesday, following the announcement of a landmark 22-year power purchase agreement (PPA) with Google. The deal is set to reshape the financial outlook for Finland's Loviisa nuclear power plant, extending its operational life to 2050. The market's reaction signals more than just the typical 'AI power' enthusiasm; Fortum management projects that the contract will add approximately 1.4 percentage points to the group's comparable return on net assets (RONA) over time.
At 12:39:45 p.m. Helsinki time, Fortum shares were trading at €24.27, up 13.62% from Tuesday's close of €21.36. This one-day jump is unusually sharp for a utility, prompting investors to question how much of the contract's long-term value is already priced into the stock. The deal's structure, which ramps up to cover up to 50% of Loviisa's capacity from 2030 through 2049, provides Fortum with the revenue visibility needed to justify significant capital expenditure.
Details of the Google Agreement
Under the terms of the agreement, Google will begin purchasing power at a smaller scale in 2028, scaling up to half of Loviisa's output by 2030. This committed demand underpins Fortum's investment in extending the plant's life and supports an additional 10-megawatt power increase on top of a previously planned 38-megawatt uprate expected in 2028. Loviisa, which houses two 507-megawatt pressurized-water reactors commissioned in 1977 and 1980, generates roughly 8 terawatt-hours annually—about 10% of Finland's electricity. The PPA effectively locks in a substantial portion of the plant's output to a single, creditworthy customer, reducing exposure to volatile Nordic wholesale electricity prices.
Google's separate announcement of a €13 billion investment in Finnish AI infrastructure for 2027-2028 is noteworthy, but it should not be conflated with the Fortum contract. The PPA's specific electricity price, total value, and indexation terms were not disclosed, leaving investors to speculate on the exact financial impact.
Impact on RONA and Financial Metrics
Fortum's comparable RONA stood at 11.0% for the trailing twelve months through June. Management expects the Google PPA to lift this measure by approximately 1.4 percentage points once half of Loviisa's capacity is contracted. On a like-for-like basis, that would imply a RONA of around 12.4%, a material step toward the company's 14% long-term target, though still 1.6 points short. However, the 'over time' qualifier is crucial: the PPA ramps gradually, and Fortum must still fund and execute the life-extension work. Of the roughly €1 billion Loviisa program scheduled for 2023-2050, about €700 million in capital spending and approximately 80% of individual projects remain subject to future investment decisions.
The agreement also addresses a weakness highlighted in Fortum's latest quarterly report. In Q2, comparable operating profit fell to €106 million from €115 million, partly due to lower achieved power prices. A long-term corporate buyer can smooth that price risk, although the undisclosed tariff prevents outsiders from calculating the exact earnings floor.
Market Reaction and Valuation Concerns
The bullish case is clear: Fortum has converted the biggest strategic question for an aging plant—who will buy decades of output—into contracted demand from a tech giant. This supports life extension, capacity upgrades, and better returns on an existing asset, without requiring investors to value an unbuilt reactor. However, the 13.6% share-price gain capitalizes much of that de-risking immediately, while cash returns will only materialize over time. Investors still lack key details: the contract price, escalation formula, and protections if Google's Finnish data-center buildout changes. Loviisa also carries the normal outage, regulatory, and project-execution risks inherent in a multi-decade nuclear program.
Fortum's investor call at 1:30 p.m. EEST on Wednesday is the first near-term test. Key questions include how the PPA changes the generation segment's hedge profile, when the RONA uplift begins to appear, and what return threshold governs the remaining €700 million of investment decisions. The next scheduled financial checkpoint is the January-September report on October 28.
For shareholders, the deal is genuinely strategic: it turns AI-driven electricity demand into a measurable improvement in asset returns. The stock's double-digit jump means the debate has already moved on from whether the contract matters to whether Fortum can deliver the promised return lift on time and on budget.
