Centrica just delivered the kind of headline mix markets hate: a sharp profit drop, a sudden pause to buybacks, and a clear pivot toward multibillion-pound infrastructure spending. The result was immediate. In early London dealing, Centrica (LSE: CNA) shares fell roughly 8%, putting the British Gas owner at the top of the FTSE 100 losers list as investors digested what looks like a near-term cash squeeze in exchange for long-term energy-security assets.
The company said full-year profits for 2025 slumped by almost 39%, with adjusted earnings down to £1.42bn from £2.3bn a year earlier. Management framed the reset as a consequence of tougher trading conditions and a deliberate shift in capital priorities, pausing the buyback to fund major projects across nuclear, LNG import capacity and gas storage.
Buyback pause lands as investors reprice the “returns story”
For a stock that has benefited from being seen as shareholder-friendly, the buyback pause matters as much as the earnings line. When repurchases are running, they effectively provide steady support to the share price and reinforce the idea that surplus cash is being recycled back to owners. When the programme stops, even temporarily, the market tends to ask one blunt question: is the company moving from cash returns to capital-heavy rebuilding?
Chief executive Chris O’Shea argued the pause is a value decision, not a retreat. “Pausing the buyback enables us to prioritise investment that creates lasting value for shareholders,” he said, while continuing to deliver “reliable, affordable energy” through the transition. Investors, however, are weighing that promise against near-term volatility and a cash flow profile that has clearly tightened.
British Gas numbers: customer growth, softer usage, lower profits
The British Gas retail arm is a core part of the Centrica story for UK readers because it sits directly on household demand and sentiment. In 2025, British Gas reported lower profits even as it nudged customer numbers higher. Adjusted profits in the supplier unit fell to £309m from £364m the year before, while the number of household customer accounts rose by 1% to almost 8 million.
The key drag was demand. Milder weather meant households used less gas and electricity, squeezing earnings in a business where volumes and margin discipline do much of the heavy lifting. It’s a reminder that for all the talk of strategic infrastructure, day-to-day retail performance can still set the tone for the share price when the market is already anxious.
Big-ticket investments: Sizewell C, Grain LNG and Rough gas storage
Centrica’s new capital agenda is centred on regulated and contracted assets that are designed to pay back over years, not quarters. The centrepiece is Sizewell C: the company has outlined a £1.3bn capped investment in the 3.2 gigawatt nuclear project in Suffolk, including an equity commitment of £376m as part of revenue commencement arrangements.
Alongside nuclear, Centrica has moved deeper into LNG import infrastructure. The group completed the acquisition of a 50% stake in the Grain liquefied natural gas terminal for around £200m of equity, within a wider transaction valuing the asset at about £1.5bn enterprise value alongside Energy Capital Partners. It also continues to push plans to invest billions into its Rough gas storage facility, positioning the site as a strategic resilience asset as the UK manages supply security and seasonal demand swings.
Cash flow flips: capex jumps, free cash turns negative
The market reaction makes more sense once you line up the spending trajectory. Capital expenditure climbed to £1.23bn in 2025 from £564m a year earlier. That jump helped drive a £167m free cash outflow, a sharp reversal from a £989m inflow in 2024. For investors, that’s the pivot in one line: from harvesting cash to deploying it.
Operationally, the earnings decline was broad. Adjusted EBITDA fell to about £1.4bn from £2.3bn, while adjusted operating profit declined to £814m from £1.55bn. The drivers were familiar across UK energy: lower commodity prices, outages across the UK’s nuclear reactor fleet, and weaker gas trading conditions that reduced opportunities and lifted caution.
Dividend rises even as earnings fall
One detail investors will debate is the dividend decision. Despite lower earnings, Centrica increased its full-year dividend by 22% to 5.5p per share and said it returned £1.1bn to shareholders over the year. That is a strong signal of confidence — but it also raises the stakes for execution on the investment programme, especially if the retail environment stays soft and trading conditions remain choppy.
Net cash is also moving in the direction the market notices. Adjusted net cash stood at just under £1.5bn at year-end, down from £2.9bn, reflecting the step-up in investment into regulated and contracted assets.
Asset sales reinforce the “recycle capital” message
Centrica has also been trimming around the edges to fund the shift. In recent weeks the company completed sales of three non-core energy solutions businesses in Europe for more than £80m, and it has been recycling capital out of legacy positions, including a final disposal from Spirit Energy assets linked to the North Sea, with a total transaction value around £98m. The strategic message is consistent: sell what doesn’t fit, redeploy into long-life infrastructure.
What investors will watch next
The immediate market question is whether today’s selloff is a reset or the start of a longer re-rating. In the near term, investors will want clearer visibility on how quickly Sizewell C and Grain LNG translate into stable, contracted returns, and whether British Gas can lift profitability while household usage remains weather-sensitive. They’ll also watch whether the buyback pause is brief, or a longer stand-down while capex stays elevated.

The takeaway: Centrica is asking investors to trade a near-term buyback tailwind for a long-term infrastructure story. With profits down, capex up, and cash flow swinging negative, the market is demanding proof — and until it gets it, CNA looks set to stay volatile inside the FTSE 100.
