Gwen Hofmeyr of Maiden Financial presented his thesis on Sif Holding NV (Netherlands: SIFG) at Wide-Moat Investing Summit 2026.
Thesis summary:
Sif Holding is Europe’s largest producer of offshore wind monopile foundations, with 35-40% share from plants in Roermond and at Rotterdam’s Maasvlakte II. Gwen frames Sif as a protected Dutch monopoly: every Dutch project since 2020 has named it as monopile supplier, Chinese firms are barred from Dutch tenders, and it is the only monopile producer with European Commission “Strategic Project” status. Equinor owns about 14% plus €50m of convertible preferred and names Sif on its fixed-foundation projects abroad, such as Dogger Bank.
The shares recently traded about 61% below their 2024 high on industry distress and company missteps. 2024 and 2025 brought failed European tenders, a US moratorium on new offshore wind, and a nine-month halt on Empire Wind 1; the failed tenders also opened a backlog gap from H2 2027 through 2028. Sif’s €330m roboticized Maasvlakte II line missed its ramp, and 2025 EBITDA of €28m fell far short of €90-120m guidance, the company’s first loss-making year since 2018.
Gwen argues the setup is reversing: the Hamburg Declaration, signed by 10 nations in January 2026, targets 300GW of North Sea capacity by 2050, and the Netherlands guides to 70GW versus 4.7GW today. The Dutch government released €1bn to secure 2GW of new capacity in 2026, and tenders are shifting from uncapped negative bidding to CfDs. Competitors are faltering: Korea’s SeAH Wind has yet to sell a monopile from its Teesside plant, and EEW’s US subsidiary filed for Chapter 11.
Because steel is a contractual pass-through, Gwen tracks contribution and EBITDA per tonne rather than revenue. Q1 2026 EBITDA reached €15m, up about 240% year over year, with €21m adjusted, equal to 76% of all of 2025’s adjusted EBITDA; EBITDA per tonne rose to about €250 from €160 in 2025. Egeria Capital owns 56% and lifted at-risk management pay to 40-60% of base salary from a 20% cap, alongside a new CEO and CFO.
The shares recently traded at an EV of about €360m, a 36% discount to the roughly €565m Gwen estimates it would cost to replicate Sif’s 7m-plus square feet of capacity. At 48% utilization, the Q1 run rate of €60m of EBITDA implies about 6x EV/EBITDA; at management’s €40m-per-quarter full-ramp target, 2.3x. Five-year adjusted FCF of €242m exceeds the €170m market cap, and €80m of FCF in a good year implies 2x P/FCF. Risks include inflation, rare earth supply, sabotage and new competitors.
