Chesterfield Special Cylinders Holdings PLC (AIM:CSC) delivered a strong FY 2025 investor update highlighting a return to profitability, improved financial results and momentum across defence, hydrogen and life cycle services. The company reported 12 percent revenue growth to 16.6 million, record second half revenue, a swing to 0.8 million adjusted EBITDA profit from a prior loss, improved margins, and a strengthened balance sheet supported by the sale of the PMC division which boosted cash to 2.1 million and enabled debt repayment. Order intake and the order book increased sharply, driven by overseas defence contracts, integrity management services and the company’s first major UK hydrogen storage milestones under the BP Aberdeen project. Management reaffirmed its 2028 growth strategy including a revenue target above 30 million, 15 percent plus EBITDA margins before central costs, doubling overseas defence sales, expanding the order book linked to long term submarine programs, and scaling hydrogen to 30 percent of group revenue as UK allocation rounds progress. The investor presentation emphasised visibility from naval programmes in the US, UK, Australia and Canada plus rising NATO defence spending, while the hydrogen outlook benefits from UK clean energy incentives and upcoming contract awards through 2026. Record 2025 integrity management revenue supported recurring high margin service income with a target to maintain at least 30 percent of revenue from life cycle services. Operational improvements, workforce development and factory readiness are expected to drive further EBITDA and margin expansion in 2026 when contract phasing again skews revenues to the second half. Management reiterated confidence in order conversion, earnings growth and shareholder value creation supported by a stronger order book, a clear growth strategy, and exposure to defence and hydrogen markets with long term structural demand.
