BAE Systems (LON:BA) shares ticked up approximately 0.5% to 1,849 pence in late Friday trading on the London Stock Exchange, following a slight delay in data release. The modest uptick provided a brief respite after three consecutive sessions of losses, though the stock remains 8.7% below Monday's close of 2,025 pence. Thursday's 4.47% decline was a key contributor to the weekly decline.
The broader concern revolves around valuation. BAE has maintained its 2026 underlying earnings per share (EPS) growth forecast of 9% to 11%, based on 75.2 pence. At current levels, the forward price-to-earnings (P/E) ratio has compressed to between 22.1 and 22.6 times, down from 24.3 to 24.7 times at Monday's close. This represents a reduction of roughly 2.2 P/E points. The forward P/E metric uses projected earnings to compare share price to annual earnings.
The valuation reset was underscored by a price target cut from Jefferies on Friday. The brokerage lowered its BAE price target to 2,100 pence from 2,200 pence, maintaining a "hold" rating. The new target implies a 13.6% upside from the latest price of 1,848.5 pence, compared to a 19% premium previously—a decline of about 5.4 percentage points.
In a related move, Jefferies upgraded Leonardo (BIT:LDO) to "buy" and placed it at the top of its European aerospace and defense list, replacing Rheinmetall (ETR:RHM). Analyst Chloé Lemarié and her team cited Leonardo's stake in missile group MBDA as a potential catalyst for upside in its 2029 outlook, reflecting a shift in preference toward defense electronics and air-defense sectors.
This shift is significant for BAE as the market becomes more selective within the defense sector, which continues to benefit from robust military spending. Investors are no longer simply paying for defense exposure; they are increasingly differentiating stocks based on valuation, contract performance, and the timing of profit realization.
Despite the week's decline, BAE still commands a notable premium on its trailing earnings. According to FTSE Russell data, the trailing P/E stood at 26.9 at Thursday's close, well above the UK aerospace and defense sector average of 22.2 and Babcock International Group's (LON:BAB) 22.1. This places BAE at approximately a 21% premium over both benchmarks.
The elevated premium means BAE has more to prove. The company's latest update reaffirmed sales growth guidance of 7% to 9%, underlying EBIT growth of 9% to 11%, and free cash flow expected to exceed £1.3 billion. EBIT, or earnings before interest and tax, is BAE's chosen profit metric, while free cash flow represents cash left after operational and capital expenditures. CEO Charles Woodburn stated that BAE "delivered a strong start to 2026, underpinning our full-year guidance."
The next major test for BAE comes on July 30 with the release of half-year results. Investors will be closely watching whether order flow and contract milestones are driving profit and cash generation, rather than merely focusing on backlog size. The recent stock decline has shaved about two P/E points off the multiple for 2026 earnings guidance.
Downside risks remain. Contract timing could impact near-term cash conversion, even if full-year targets are maintained. Currency fluctuations are another factor: BAE notes that a five-cent move in sterling versus the dollar would change annual sales by approximately £500 million, EBIT by £70 million, and EPS by about 1.4 pence. Further sector-wide valuation declines could offset earnings growth.
Friday's modest uptick appears more like a stabilization than a reversal. BAE now trades at roughly 22 times forecast earnings, a discount compared to earlier in the week. However, with a trailing multiple still about 20% above the UK sector average, the stock cannot be considered cheap yet.
