Capital Drilling warns on revenue

■ Emerging market-focused Capital Drilling yesterday warned on its full-year revenue, as a result of industrial action in Egypt and a weaker than expected performance in Tanzania, sending its shares down 17 per cent to close at 39p. Capital Drilling derives 40 per cent of its revenues from these two key countries. The drilling company said yesterday that revenues rose 26 per cent to $40.9m (£25.6m) for the three months to September, up from $32.5m last year. It added that the third performance was “solid, albeit below consensus forecasts”.
