Rolls-Royce reported underlying profit before tax of £2.5bn for the first half of 2026, up 48% year-on-year, and raised its full-year profit guidance as earnings improved across all divisions. The update came as London’s FTSE 100 traded flat, with global markets subdued after the US Federal Reserve held interest rates steady and Iran carried out fresh attacks, unsettling investor sentiment.
How did Rolls-Royce perform in the first half of 2026?
The engineering group’s revenues climbed by £2bn compared with a year earlier to reach £11.3bn, reflecting broad-based gains across its civil aerospace and defence businesses. Statutory profit, however, fell to £1.9bn, roughly half the prior year’s figure, a swing the company attributed to the timing of payments rather than any deterioration in underlying trading.
Management highlighted progress in civil aerospace, where aftermarket profitability improved and the number of grounded aircraft awaiting engine repairs was effectively eliminated, easing pressure on airline customers. In its defence arm, Rolls-Royce said it had reached several milestones in autonomous propulsion technology, reinforcing what it described as a leading position in the sector.
Our transformation continues to deliver, and we are demonstrating that Rolls-Royce is now a very different company to that of the past, the company said.
Why is the FTSE 100 barely moving despite strong corporate earnings?
The FTSE 100 stayed close to flat on the day because upbeat company results, including Rolls-Royce’s raised guidance, were offset by broader macroeconomic caution. The Federal Reserve’s decision to hold US interest rates steady removed one source of uncertainty but also signalled policymakers are in no rush to cut borrowing costs, tempering expectations for cheaper credit in the near term.
Adding to the cautious mood, renewed Iranian attacks stoked concerns about geopolitical instability and potential disruption to energy markets, prompting investors to weigh strong individual earnings against wider risks. Global stock markets more broadly slipped as traders balanced the Fed’s steady-rate stance with the escalating tensions in the Middle East.
What does this mean for investors and the wider market?
Rolls-Royce’s upgraded profit forecast underscores how individual companies undergoing turnarounds can outperform even when the broader index stalls. For investors, the divergence between a resilient blue-chip earnings story and a flat FTSE 100 illustrates how macro risks, including central bank policy and geopolitical shocks, can overshadow positive corporate news in the short term.
