Rolls-Royce Holdings (LON:RR) has ended 2025 as the standout leader of the UK blue-chip index.
While the broader FTSE 100 enjoyed a historic year with gains of over 20%, Rolls-Royce operated in a different league, with growth on three fronts, civil aviation, defence, and energy.
With its share price surging by 95.1% year-to-date, the company’s valuation has neared the £100bn mark, a milestone that seemed impossible during the post-pandemic lows of 93p.
This rally was driven by a fundamental shift in how the business extracts value. Under CEO Tufan Erginbilgiç, the company moved to a high-margin “power-by-the-hour” service model.
As wide-body engine flying hours reached 111% of 2019 levels by late 2025, this record activity generated a massive influx of cash. The Trent XWB engine fleet became the primary profit driver, with civil aerospace margins expanding well beyond analyst forecasts.
Two specific catalysts provided long-term structural clarity during the year. In November 2025, the UK government confirmed Rolls-Royce as the lead for the national Small Modular Reactor (SMR) programme, with Wylfa selected as the first deployment site. Additionally, the steady ramp-up of the AUKUS submarine programme ensured the Defence division remained a predictable, cash-generative floor for the group.
This liquidity allowed the board to pivot from repairing the balance sheet to rewarding shareholders. Following the completion of a £1bn share buyback in November, the company announced a further £200m interim buyback on 16 December.

This programme bridges the gap until the 2025 full-year results in February. This aggressive capital return policy, combined with the first full year of reinstated dividends, has convinced institutional investors that the growth phase is now firmly established.
By late December, the share price of 1,148p has pushed the price-to-earnings (P/E) ratio to 41.6. While the 2025 performance has been historic, the challenge for 2026 will be navigating execution risks in a global aerospace supply chain that is still struggling to keep pace with delivery targets.
