Rolls-Royce raised its full-year profit and cash flow guidance after reporting stronger-than-expected first-half results, supported by growth across its civil aerospace, defense and power systems businesses.

Underlying operating profit rose 46% year on year to £2.5 billion ($3.3 billion) in the first six months of 2026, while revenue increased more than 24% to £11.3 billion.

The company now expects full-year underlying operating profit of £4.7 billion to £4.9 billion, up from previous guidance of £4 billion to £4.2 billion. It also raised its free cash flow forecast to £3.8 billion to £4 billion, compared with £3.6 billion to £3.8 billion previously.

Shares rose as much as 6% in early trading before paring gains to trade about 4% higher.

Data Center Demand Supports Power Systems

Chief Financial Officer Helen McCabe told CNBC that orders in Rolls-Royce’s data center power business increased by more than 50% in the first half as operators invested in backup and on-site power systems.

The company has benefited from growing demand for power infrastructure as data center operators expand capacity.

Defense Spending Provides Additional Support

McCabe also said Rolls-Royce expects to benefit from higher defense spending in the U.K. and across NATO countries. She cited the U.K.’s long-term defense investment plan, which provides funding visibility through 2030 and beyond.

“We’ve had very positive initial conversations with the new government,” McCabe said, adding that the company supports its focus on growth, defense and industrial manufacturing.

Turnaround Continues

Chief Executive Tufan Erginbilgic said the company’s transformation strategy continued to deliver results. “Our transformation continues to deliver,” he said in a statement. “We have unlocked new growth opportunities across the Group.”
