2025: revenue DKK 5.57B, EBIT DKK 237M, equity DKK 667M
2024: revenue DKK 5.64B, EBIT DKK 268M, equity DKK 627M
2023: revenue DKK 5.03B, EBIT DKK 258M, equity DKK 543M

Financial Resilience Score: 8/10

Semco Maritime demonstrates strong financial resilience with revenue tripling from DKK 1.88bn in 2020 to DKK 5.64bn in 2024, while EBIT scaled almost 10× over the same period. The company maintains a solid balance sheet with DKK 794m in cash, no significant interest-bearing debt, and an equity ratio of ~27%. Equity nearly quadrupled from DKK 161m to DKK 627m, largely from retained earnings, and return on equity remains strong at 34% in 2024. The company benefits from patient, long-term ownership by the Obel family (C.W. Obel A/S / Det Obelske Familiefond) since 1996, providing stability. A robust order book of DKK 5.9bn (88% Renewables) at year-end 2024 provides roughly one year of forward revenue coverage. The successful strategic pivot toward renewables (58% of revenue in 2024, up from 24% in 2021) aligns the business with long-term energy transition trends. However, risks include cyclicality and political exposure in offshore wind (particularly US policy uncertainty affecting the Coastal Virginia Offshore Wind project), lumpy contract margins, declining Conventional oil & gas activity, DKK 6.14bn in joint & several consortium guarantees, and an unquantified foreign tax contingency. 2025 guidance is cautious with flat revenue and EBITDA margin of 5-7%.

Key strengths: Revenue tripled from DKK 1.88bn to DKK 5.64bn over 4 years (CAGR ~31.6%), Strong cash position of DKK 794m with minimal interest-bearing debt, Long-term patient ownership by Obel family foundation since 1996, Order book of DKK 5.9bn provides ~1 year forward revenue coverage, Successful strategic pivot to Renewables (58% of revenue, targeting 65% by 2027), Equity nearly quadrupled to DKK 627.5m, driven by retained earnings, Return on equity of 34% in 2024, Blue-chip client base including TotalEnergies, Dominion Energy, Topsoe

Risk factors: US political/policy risk affecting Coastal Virginia Offshore Wind project, Cyclicality and lumpy margins in large EPCI substation contracts, Declining Conventional oil & gas exposure (-9% in 2024, further decline expected), Unquantified foreign tax authority claim contingency, DKK 6.14bn joint & several consortium guarantees (off-balance-sheet), Currency risk across USD, GBP, NOK, EUR, SGD, Supply chain/geopolitical risks from Russia/Ukraine and Middle East, Safety TRIF of 3.5 in 2024 missed target of <1.5, 2025 guidance flat with margin compression risk
