Listen to the news

TMX Group has delivered a strong multi year share price performance, and the question now is whether that move is fully backed by the earnings that support today’s valuation.

  • Over the past 5 years, TMX Group has returned 114.1%. This puts real weight on whether the current earnings base can carry that kind of share price progress.
  • The recent pricing of a C$1.1b senior unsecured debenture offering may reshape the firm’s capital structure. This can influence future interest costs and the portion of earnings available to equity holders.

If you are considering TMX Group at C$53.11 based on its earnings profile, it can help to compare it to 3 high quality undervalued stocks for a broader perspective.

Is TMX Group Getting Expensive on Earnings?

The P/E ratio is a relevant measure for TMX Group because earnings are a core reference point for most exchange operators. On this basis, the stock trades on about 24.3x earnings, compared with roughly 6.4x for the wider capital markets sector and around 18.1x for closer peers. That represents a clear premium to both the broad industry and similar businesses.

Because the recent debenture issue and acquisitions have raised expectations around TMX Group, the current P/E also sits above the level suggested by a more tailored fair multiple that accounts for its profitability profile and risk. This indicates that the shares screen as overvalued on earnings today. Any investor considering TMX Group therefore has to evaluate whether its business mix and balance sheet changes justify that higher valuation relative to other capital markets stocks.
