Priced for more growth than it has delivered
At today's price of £20.70, the market is pricing in revenue growth of about 13.6% a year for 2026E–2030E, holding the rest of your base case. BAE Systems plc's revenue grew 10.1% a year between 2022 and 2025, so the price asks for more than it has delivered.
Your base case assumes 7.2% revenue growth a year on average, less than the price implies, and values the shares at £15.41, 26% below today's price.
If your base case comes true, the whole business would return about 7.4% a year at today's price, 1.4 percentage points less than the 8.8% a year the model requires (the WACC).
About 68% of today's price pays for future growth. The other 32%, £6.55 a share, is what 2025 operating profit after tax is worth if it never grows.
Across 2,000 simulated futures around your base case, the middle 80% of values runs from £10.50 to £22.47 a share, and 16% of them are worth more than today's price.
Business health grade B (74 out of 100): looks mostly healthy, with 4 strengths and 1 red flag (top concern: balance sheet in the grey zone).
Educational, not investment advice. “Favourable” means the numbers lean in today's price's favour; “Caution” means the price asks a lot of the future.

2025 against 2024. Above −1.78 the pattern resembles companies later found to have manipulated earnings; some analysts use a stricter −2.22. SGAI was missing and set to the neutral 1.0. * Not in the data, so set to the neutral 1.0: SGAI.
Piotroski F-score (Joseph Piotroski, 2000): nine pass-or-fail tests of profitability, debt, liquidity and efficiency, each comparing the latest year with the one before. 7 or more is strong; 3 or fewer is weak.
Altman Z'' (Edward Altman, 1995, the version for non-manufacturers and emerging markets): combines working capital, retained earnings, operating profit and book equity relative to the balance sheet. Above 2.60 is the safe zone, below 1.10 the distress zone.
Beneish M-score (Messod Beneish, 1999): eight ratios that, in his study, separated companies later found to have manipulated earnings. Above −1.78 resembles that pattern. It is a prompt to read the notes to the accounts, not an accusation.
Grade: a 0 to 100 blend (Piotroski 40%, Altman 20%, Beneish 15%, the ratios 25%, re-weighted when a part is missing): A from 80, B from 65, C from 50, D from 35, E below.
All three screens were built on US companies and annual accounts from Yahoo Finance, which can be incomplete. Lenders, insurers and holding companies get financial-firm ratios instead of the Altman and Beneish screens.
Price targets and ratings from the brokers' analysts who cover the stock, as Yahoo collects them. Their opinion, not this app's; set against the model so you can see where you differ.
20 analysts' average 12-month target is £23.14, +11.8% against today's £20.70 (median £23.38). The range runs from £17.00 to £26.20.
Your value estimate of £11.20 is 52% below the analysts' average: a big gap is worth explaining, it usually comes down to growth or margin assumptions.
Targets are usually for 12 months ahead and tend to run optimistic; brokers that cover a company often do business with it. Counts and targets come from different updates, so they may not match exactly.
How much the shares have swung and how far they have fallen over five years. Risk repeats far more reliably than direction, so this is the honest kind of forecast: how far the price may move, not which way.

A reverse DCF: the constant revenue growth, or the constant EBIT margin, that makes the DCF equal today's price, holding everything else in your base case.
The yearly return on the whole business at today's price if your base case comes true, against the return the model requires and what a government bond pays.
If your base case comes true, today's price earns about 7.4% a year, 1.4 percentage points less than the 8.8% the model requires.
Every £100 of share price buys £3.49 of today's profit a year, less than the £4.93 of interest the bond pays: the price counts on profits growing.
Expected return (an internal rate of return). Imagine buying the whole company at today's price: its shares and its debt, less its cash. The expected return is the yearly rate that makes the free cash flows in your base case, plus the value after 2030E growing at 3.0%, add up to exactly today's price. When it is above the WACC, the price sits below your DCF value. It only comes true if the forecast does.
Earnings power value. What the business is worth if its last reported operating profit never grows or shrinks (a simplified version of Bruce Greenwald's method). It treats depreciation as the spending needed to stand still, and uses reported rather than average profit, so one unusual year moves it.
Earnings yield is the profit a year you buy with each unit of price (the P/E turned upside down). Free cash flow yield is the same idea with next year's forecast cash flow.
