With new deals in data and credit intelligence reshaping the group, investors are increasingly asking how much of that long run is backed by underlying capital efficiency rather than just sentiment.

Does London Stock Exchange Group Look Pricey on Excess Returns?
The Excess Returns model looks at how much value London Stock Exchange Group creates above the cost of the equity capital backing it. Here, the focus is on how efficiently the business turns a pound of shareholder funds into earnings over time.
On the model's inputs, book value sits at £37.63 per share and is projected to trend toward a stable £39.91, while stable EPS is £5.54 per share. With an average return on equity of 13.87% against a cost of equity of £3.59 per share, the framework implies an excess return of £1.95 per share. This is what the model treats as value created beyond investors' required return. Those excess returns, combined with the stable EPS profile, are what drive the estimated intrinsic value. The Excess Returns projections put this meaningfully below the current £94.44 share price.
LSEG's planned US$3.54b Octus acquisition, and the higher 2026 guidance that came with it, helps explain why the market may be willing to pay a premium to what the Excess Returns model suggests based on book value and projected earnings alone. If you want to see how those assumptions compare with a fuller market view, you can check the detailed Excess Returns workup and peer context.
