Rolls-Royce and BAE Systems both raised their profit forecasts for 2026 on July 30. The reason they gave: governments are committing to spend more on defence (The Guardian).

Rolls-Royce raised its expected profit — the money left over after covering the costs of running the business — to between £4.7 billion and £4.9 billion for the year. That is up from an earlier estimate of £4.0 billion to £4.2 billion. The company also raised its forecast for free cashflow, which is the cash a company generates after paying for major investments like equipment or buildings, from £3.6 billion–£3.8 billion to £3.8 billion–£4.0 billion. Shares in Rolls-Royce rose 5.5%, making it the biggest gainer in the FTSE 100, the index of the 100 largest companies on the London stock market. The upgrade came alongside the company's H1 2026 trading update and is a notable shift from the position taken at its AGM (annual general meeting, a yearly update for shareholders) on April 30, when Rolls-Royce said its full-year guidance of £4.0bn–£4.2bn profit and £3.6bn–£3.8bn free cashflow remained unchanged (Rolls-Royce).

BAE Systems raised its earnings growth forecast to 10%–12%, up from a previous estimate of 9%–11% (The Guardian). The company's HY 2026 Half Yearly Report, also published July 30, states that operating profit increased 13% in the first half of the year and basic earnings per share (the portion of profit assigned to each share of stock) rose 6% to 34.1p. The report was prepared using an exchange rate of $1.32 to £1 (BAE Systems). Reuters reported that BAE stated the upgraded guidance reflects "both the strength of execution and the structural tailwinds supporting the sector" (Reuters).

Both companies named specific contract wins as evidence of the spending environment. BAE Systems cited a £5.9bn contract with the British government to complete the nuclear deterrent submarine HMS Dreadnought, as well as a contract to provide Turkey with training, support equipment, and services for 20 Typhoon aircraft (The Guardian). Rolls-Royce's July press release activity spans its Defence division (covering the UK, US, France, and Germany), a Nuclear press release related to submarines in the UK, multiple Civil Aerospace releases concerning the Trent 1000, Trent XWB, Trent 7000, and sustainability initiatives, and Power Systems division releases covering mtu naval projects in Asia Pacific, electrification in Brazil, and engineering and manufacturing in the United States (Rolls-Royce).

The trajectory for both companies has been building across recent reporting cycles. BAE Systems posted a 12% rise in full-year profit for 2025 in February 2026 and gave initial 2026 guidance of 7%–9% higher sales and 9%–11% higher operating profit (Reuters). That operating profit range had already been carried forward from the company's 2025 half-year results, where BAE guided for full-year sales growth of 8%–10% and underlying EBIT growth of 9%–11% (BAE Systems). A November 2025 market update confirmed that full-year 2025 guidance was unchanged across all metrics from the upgraded half-year figures (BAE Systems). For 2026, the July 30 upgrade narrows the gap between BAE's actual performance (13% H1 operating profit growth) and its forward guidance, which moved up by one percentage point at both the floor and ceiling.

Tufan Erginbilgiç has served as chief executive of Rolls-Royce since 2023. Charles Woodburn is chief executive of BAE Systems (The Guardian).

The broader context here is one of sustained, government-driven demand flowing directly into order books and forward guidance. The £5.9bn Dreadnought contract and the Turkish Typhoon deal are not one-off events but instruments of national procurement programmes that run on multi-decade timelines. Think of it like a city signing a 20-year contract with a construction firm rather than hiring a builder for one job at a time. When BAE's leadership invokes "structural tailwinds," they are referring to this pipeline: national governments committing to multi-year defence investment cycles that translate into contracted revenue with a high degree of visibility. For Rolls-Royce, the breadth of July's press release activity, spanning Defence, Nuclear, Civil Aerospace, and Power Systems across multiple geographies, suggests the upgraded guidance draws on strength across the portfolio rather than a single programme. The jump from £4.0bn–£4.2bn to £4.7bn–£4.9bn in profit guidance in the three months since the April AGM is a substantial upward revision, and it raises the question of whether the April figure was genuinely conservative or whether contract milestones landed in the interim that materially shifted the outlook.

For investors and defence analysts, the signals are straightforward. Both companies are raising guidance in the same window, attributing the upgrade to the same cause, and backing it with named contracts. The convergence of their messaging around government defence spending commitments suggests a sector-wide demand environment rather than company-specific outperformance. Whether the spending cycle continues to deepen, or whether these upgraded forecasts begin to price in a peak, will depend on national budget cycles and geopolitical developments that neither company controls but both are positioned to benefit from.
