Derby Capital is a highly-refined disciplined capital partner focused on attractive risk-adjusted returns in the oilfield service and equipment markets; we will also consider similar attractive opportunities in the general C&I markets when suitable.

Our geographic preference is the continental US and US GOM, with selective consideration of investments in Canada.

We seek to make investments of debt and equity in companies that are well-established and have strong leadership.

In a horse race, all competitors are running in the same direction. It takes more than just a fast horse or an earnest jockey to win. Only the best prepared, most focused and committed team of horse and jockey will finish first. – Ross Bartley
