Wintershall bonds are a part of Harbour Energy, a London-listed oil & gas producer. Wintershall Dea was created in 2019 from the merger of Wintershall Holding and DEA Deutsche Erdoel. In September 2024, its exploration and production business was acquired by Harbour Energy. This deal was transformational: Harbour’s production base doubled, and Wintershall’s bonds are now backed by the full Harbour group. The Harbour Energy group has a strong ownership base: BASF holds about 40%, LetterOne around 15%, and the remaining 45% is held by investors on the London Stock Exchange.
Harbour produces around 470,000 barrels of oil equivalent per day, which is roughly the size of Aker BP in Norway or APA Corporation in the U.S. For comparison, this is about one-tenth of the scale of ExxonMobil. The production mix is 60% natural gas and 40% oil.
The company’s reserves cover around 8 years of production, with further potential in contingent resources. By geography, Norway accounts for 36% of production, the UK 32%, Argentina 12%, with Mexico, North Africa and Germany making up the rest. Mexico in particular is promising, with more than 400 million barrels of resources identified, and investment decisions expected around 2026.
Costs of production are competitive: in the first half of 2025 the group produced at $12,4 per barrel, with the plan to keep the full-year average at $13,5 per barrel. With Brent oil prices currently around $70, this means Harbour makes a healthy margin even if markets weaken. The lowest-cost operations are in Norway and Argentina.
Harbour is firmly investment grade, and is committed to keeping its balance sheet strong. Fitch expects EBITDA leverage below 1× through 2028, while S&P projects funds from operations to debt at 40–45%, which is comfortably within investment-grade territory.
The company already cut net debt by $0,9 billion in H1 2025, with plans for another $0,5–1,0 billion reduction over the next years. Annual production is expected to stay near 450,000 barrels/day, with operating costs below $15/boe and capital expenditure under $2 billion per year from 2026.
In the near term, Harbour actively hedges to protect its cash flow: about 45% of its H2 2025 liquids exposure and 50% of its European gas is hedged. While this mainly secures short-term cash generation, it shows the company’s cautious approach to risk management.
The bond itself has a low coupon of 1,823%, but trades significantly below par, so the effective yield is much more attractive. The minimum trading size is €100,000 at Interactive Brokers, but Trade Republic offers fractional access from €1.
