Star Energy completes sale of Croatian geothermal subsidiary IGeoPen to Enna Geo for up to $3.3 million
AIM-listed Star Energy has wrapped up the sale of its Croatian geothermal subsidiary IGeoPen to Enna Geo. The company received an initial cash payment of $1.46 million — its cut of a $1.68 million total that reflects its 71% stake in IGeoPen’s direct parent, A14 Energy. The deal closed following the April 24, 2026 announcement, and it comes with a potential earn-out of up to $1.68 million tied to the future commercial operation of geothermal power plants across three Croatian licenses.
Deal terms and financial consideration
The $1.68 million upfront payment was split according to A14 Energy’s shareholder structure. Star Energy holds 71%, with the remaining 29% going to JV partner Peninsula International — which is why Star Energy’s share lands at $1.46 million $1.46 million rather than the full headline number.
There’s also a performance-linked earn-out. Enna Geo pays $560,000 per license when a geothermal power plant on each of the three Croatian licenses reaches commercial operation. If all three get there, Star Energy’s earn-out share could hit $1.68 million, bringing total potential receipts to $3.14 million. That structure lets Star Energy keep some upside from Croatian geothermal development without having to fund any of it.
Add those together — the $1.46 million receipt and the $5.82 million release — and Star Energy has enough to repay $3.02 million of its Kommunalkredit facility.
Impact on Star Energy’s balance sheet and debt position
The most immediate financial win here isn’t the cash received — it’s the cash unlocked. Closing the sale releases $5.82 million in restricted cash that had been tied up in commitments under the Croatian licenses. That’s a much bigger number than the initial payment, and it gives the company’s liquidity a real boost.
Add those together — the $1.46 million receipt and the $5.82 million release — and Star Energy has enough to repay $3.02 million of its Kommunalkredit facility. That’s a meaningful dent in gross debt.
The timing works out too. A scheduled amortization payment is due in December 2026, and once that goes through alongside this early repayment, the outstanding Kommunalkredit balance drops to $7.73 million. What’s left gets repaid in semi-annual installments through 2027 and 2028 — a manageable schedule given the company’s stated cash generation.
One structural benefit is easy to overlook: by exiting Croatia, Star Energy cuts future capital commitments and ongoing costs tied to those licenses. Not just a one-time cash event, but a cleaner balance sheet going forward.
Strategic rationale: Refocusing on UK operations
This isn’t purely a financial transaction — it’s a deliberate narrowing of focus. Star Energy says management will now concentrate on UK oil and gas operations and a UK geothermal development platform, the areas where the board sees the clearest path to shareholder returns.
One asset sits at the center of that strategy: £258 million ($343.14 million) in UK tax losses. The company sees real potential in accelerating the utilization of those losses through inorganic acquisitions. That ambition is backed by a recently completed $12.10 million equity raise, and combined with strong operating cash flows and the Croatian sale proceeds, Star Energy says it now has meaningful capacity for disciplined, value-accretive deals.
CEO Ross Glover was direct about the thinking. “It brings greater strategic focus to the Group,” he said. “Our capital, management attention and operational capability can now be concentrated on those areas where we believe we have the clearest opportunity to generate attractive returns.” He also noted the transaction strengthens the platform the company laid out at its interim results — converting a stronger financial position into profitable growth.
Background: Star Energy’s portfolio and geothermal context
Star Energy trades on AIM and operates primarily in UK oil and gas production. Its Croatian geothermal interests — held through IGeoPen and A14 Energy — were part of an earlier push into international diversification. That chapter is now closed.
Geothermal energy development in Croatia remains at an early commercial stage. None of the three licenses involved in this deal currently have operating power plants, which is exactly what the earn-out structure reflects: payments only trigger if and when a plant reaches commercial operation. That additional $1.68 million in potential proceeds isn’t guaranteed — it’s conditional. On the UK side, Star Energy says it’ll keep a geothermal development platform, but on capital-efficient terms, and has signaled it’ll continue pushing for policy changes it sees as necessary to attract broader investment into the sector.
What the deal means for Star Energy going forward
The IGeoPen sale delivers immediate cash, frees up a larger pool of restricted funds, cuts debt, and removes ongoing capital obligations in a non-core market. The earn-out leaves a small window open for future Croatian upside — without Star Energy having to fund any of it.
The direction is clear: simplify the portfolio, reduce leverage, and position for UK-focused growth, especially acquisitions that could put that $343.14 million tax loss pool to work. Whether that translates into the returns Glover described will depend on execution, deal flow, and how UK energy policy develops around geothermal investment.
