A busy session for small and mid-cap oil and gas names was anchored by contract wins and earnings guidance from Gulf Marine Services, while Capricorn Energy delivered a double dose of corporate news, a court-sanctioned debt recovery from Waldorf Production and an early repayment of its own junior debt. Elsewhere, an M&A endorsement, a record quarter, and a planning application for a long-contested onshore well rounded out a news-heavy day.
Gulf Marine secures Africa and Latin America entry with two new contracts
Gulf Marine Services (AIM:GMS) secured a 170-day firm charter, with options, for a newly acquired self-elevating support vessel at what it described as attractive day rates, a deal that takes the company into Africa for the first time. Alongside that, Gulf Marine signed a one-year third-party vessel management contract covering Latin American operations. The two awards lifted the group's backlog to USD 666m. Shares rose 4.16% to 20.227p.
Gulf Marine simultaneously reiterated its full-year adjusted EBITDA guidance of USD 105m-115m for 2026, signalling that the new contracts sit within existing financial expectations rather than prompting an upgrade. The geographic diversification into Africa and Latin America nonetheless marks a strategic step for a fleet historically concentrated in the Middle East.
Capricorn recovers US$4-5m from court-sanctioned Waldorf restructuring

The news sent shares up 6.85% to 322.7p.
Separately, Capricorn announced the early repayment of US$30m of junior debt, two years ahead of schedule, funded from US$81m of collections from the Egyptian General Petroleum Corporation received year to date. The combination of debt recovery and proactive balance-sheet management gave investors two reasons to re-rate the stock in a single session.
