BAE Systems (LSE:BA.) Valuation Check After Recent Share Price Pullback

BAE Systems (LSE:BA.) has pulled back over the past month, slipping about 8% after a strong year to date. That recent weakness is catching investors attention, especially given its solid earnings growth.

See our latest analysis for BAE Systems.

The recent slide comes after a strong run, with the year to date share price return still firmly positive and the one year total shareholder return comfortably ahead of the broader market. This suggests that momentum is pausing rather than breaking.

If you are exploring the wider defence theme, this could be a good moment to compare BAE with other aerospace and defense stocks that might benefit from similar long term spending trends.

With earnings still growing, a double digit discount to analyst targets and a strong multi year run behind it, investors now face a key question: is BAE undervalued or is future growth already fully priced in?

Most Popular Narrative: 21% Undervalued

With the narrative fair value sitting above BAE Systems last close of £16.65, the story leans toward upside, hinging on sustained defence led growth.

The company's order backlog has surged to £75 billion, with a pipeline of new opportunities partly fueled by higher defense spending commitments across NATO, the US, UK, Europe, and Indo-Pacific (for example, the UK targeting 2.5% of GDP on defense by 2035, and Japan planning to double spending by 2027). This provides visibility on future revenues and supports topline growth over multiple years.

Read the complete narrative.

Curious how multi year defence backlogs, expanding margins and a richer future earnings multiple combine into that higher fair value, and what assumptions really drive it? Read on to see the specific growth runway, profitability shift and valuation change this narrative is based on.

Result: Fair Value of $21.01 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, execution is not risk free, with political budget pressures and supply chain bottlenecks potentially delaying contracts and limiting how quickly backlog converts to earnings.

Another Angle on Valuation

On earnings, BAE trades at about 25.1 times, cheaper than the wider European aerospace and defense sector at 30.4 times, yet slightly richer than its closest peers at 20.8 times. That mix of relative value and premium raises the question: how much rerating is really left?
