Does Serco Group Look Undervalued on Earnings?

The P/E ratio suits Serco Group because investors often focus on the earnings stream behind long term service contracts.

That places the stock on a modest premium to the broader sector despite a relatively contract driven model.

Against companies that operate in a similar space, the picture changes. The peer group average P/E is roughly 23.1x, so Serco Group trades at a clear discount to those comparables. The internal fair value framework, which looks at factors such as growth, profitability, risk and size, points to a higher P/E than where the shares currently change hands, so the multiple screens as undervalued on this lens.
