Canadian convenience store operator Couche-Tard has reported better-than-expected profits for the second quarter, helped by its growing operations in the US convenience store market. The Montreal-based company posted earnings of C$26m (US$20.0m), or 30 cents a share, for the second quarter to 12 October, compared to $21m, or 24 cents a share, a year earlier. Analysts had been expecting, on average, earnings of 27 cents a share, reported Reuters.
