Sunda Energy’s 2025 results are a classic small-cap oil and gas update: one hand gives you a setback, the other hands you a new strategy. The big disappointment was the postponement of the Chuditch-2 appraisal well in Timor-Leste. An appraisal well is drilled after a discovery to prove up size, quality and flow rates before development.
But this was not a year of standing still. Sunda picked up new gas exposure in the Philippines and, after the year end, signed a conditional deal to buy producing assets in New Zealand. That matters because it could shift the company from being a pure explorer burning cash into one with real production and cash flow.
Sunda Energy 2025 results summary – key figures from cash, loss and funding
| Metric | 2025 | 2024 |
|---|---|---|
| Cash reserves | £0.33 million | £3.17 million |
| Loss after taxation | £2.84 million | £2.05 million |
| Administration expenses | £1.93 million | £2.22 million |
| Operating cash outflow | £2.26 million | £1.68 million |
| Exploration and evaluation assets | £7.15 million | £5.06 million |
| Revenue | Nil | Nil |
The raw numbers are not pretty. Sunda had no revenue in 2025, losses widened and cash fell sharply. That is the financial profile of a business still relying on funding markets and asset deals rather than operating income.
Chuditch-2 appraisal well delay in Timor-Leste – setback, cause and recovery plan
This is still the heart of the investment case. Sunda has a 60% working interest in the Chuditch PSC, or Production Sharing Contract, and after the 2024 interest transfer it is responsible for 80% of project costs. That cost burden is important because it means the project is potentially very valuable, but also very demanding on funding.
The 2025 plan was to drill Chuditch-2 using a jack-up rig from nearby Australian waters. That fell apart in June 2025 because helicopter services meeting the required operational and safety standards were not available in Timor-Leste, and alternatives were not approved. It sounds mundane, but in offshore drilling logistics can kill a campaign just as quickly as geology can.
That delay had a nasty knock-on effect. The farm-in agreement with TIMOR GAP terminated, so Sunda did not get the improved cost-sharing it had lined up. Instead of falling to a 30% working interest with TIMOR GAP paying 72% of costs during the relevant period, Sunda stayed at 60% and kept the heavier funding obligation.
There is still substance here. ERCE previously assessed gross Pmean Contingent Resources at Chuditch-1 of 1.16 Tcf of gas, plus aggregated gross Pmean Prospective Resources of 1,562 Bcf across nearby prospects. Contingent resources are discovered hydrocarbons not yet judged commercial, while prospective resources are estimated volumes that still need to be discovered.
The encouraging bit is what happened after the year end. Sunda received the Environmental Licence for Chuditch-2, valid until 9 March 2028, and signed a letter of intent with Finder TIMOR-LESTE B.V. to try to secure a shared rig. That could make the drilling programme much more attractive to contractors because the combined campaign would run for almost 200 days rather than a single short well.
My view: Chuditch is delayed, not dead. That is positive. But it is also clear the project has become more of a financing and execution challenge than a straight geology story.
Philippines SC80 and SC81 gas licences – why Sunda’s 37.5% stake matters
Sunda’s entry into the Philippines is the quiet positive in these results. The company was awarded a 37.5% non-operated working interest in two offshore blocks, SC 80 and SC 81. Non-operated means Sunda is not running the day-to-day activity, which can keep early spending lower.
SC 80 already contains two discovered gas fields with estimated combined 2C Contingent Gas Resources of 574 Bcf, based on a 2015 CPR from Mitra Energy, plus a smaller gas discovery. On top of that, the CPR put overall prospective resources in SC 80 at 10.1 Tcf of gas and 247 MMbbls of associated liquids across five key prospects.
For retail investors, the real attraction is portfolio balance. Sunda was heavily dependent on Chuditch. The Philippines gives it another route to create value through seismic reprocessing and technical work before any big drilling commitments arrive.
That said, this is still early-stage. There is no near-term production here, and success is not disclosed. It is a sensible strategic move, but not the reason the shares rerate on its own.
Matahio New Zealand acquisition – why 1,028 boepd could change Sunda Energy
This is the biggest strategic development by a mile. After the reporting period, Sunda signed an agreement for the conditional acquisition of Matahio Energy NZ Limited, which would bring 100% of five production and exploration permits in New Zealand.
The headline number is average 2025 production of 1,028 boepd, or barrels of oil equivalent per day, with roughly 80% oil and 20% gas. The acquired portfolio also includes 2P reserves of 2.6 MMboe, which means proved plus probable reserves, 2C Contingent Resources of 0.5 MMboe and 2U Prospective Resources of 5.8 MMboe.
Why does this matter so much? Because producing assets can fund the business. Sunda says the effective date of the deal is 1 January 2026, so it expects to benefit from stronger oil prices seen in early 2026, including a substantial May 2026 oil lifting at exceptionally high prices. The exact realised price was not disclosed.
There are caveats. The acquisition is conditional on New Zealand government approval, expected around September 2026. The consideration is also wide-ranging: a firm component of between US$8.0 million and US$14.0 million, plus a contingent element of between US$1.0 million and US$13.0 million.
Still, strategically this looks smart. If it completes, Sunda becomes far less dependent on equity placings to survive.
Sunda Energy balance sheet, dilution and going concern risk – what investors should watch
Here is the bit investors should read twice. The company states there is a material uncertainty which may cast significant doubt over its ability to continue as a going concern. In plain English, that means management believes it can keep going, but key assumptions around funding and deal completion still have to fall into place.
Those assumptions include completing the Matahio NZ acquisition, drawing down the remaining £3.0 million of a £4.25 million convertible loan note facility, securing a working capital facility linked to the New Zealand assets, and concluding a further farm-in with TIMOR GAP or other funding for Chuditch-2.
Dilution is also part of the story. During 2025, 3,125,594,493 shares were issued on convertible loan note conversion, followed by 1,880,000,000 shares in October and 960,000,000 in November. By 31 December 2025, the share count had risen to 31,476,378,281 before the later 100-for-1 share consolidation approved in April 2026.
That does not make the strategy wrong. It just means existing shareholders have paid for survival and growth with a larger share base. In a micro-cap explorer, that is common – but it is never painless.
Retail investor verdict on Sunda Energy shares after the 2025 results
What looks positive
- Chuditch still appears technically meaningful, with large gas resources and an environmental licence now in hand.
- The Finder rig-sharing plan could materially improve the odds of finally getting Chuditch-2 drilled.
- The Philippines entry adds genuine portfolio diversification.
- The conditional New Zealand acquisition could bring immediate production, cash flow and reserves.
What looks negative
- 2025 cash fell to just £0.33 million and the company generated no revenue.
- Losses widened to £2.84 million.
- Chuditch remains delayed and still needs funding, approvals and a rig solution.
- The going concern warning is real and should not be brushed aside.
- There has already been significant dilution, with scope for more if funding needs continue.
My bottom-line take: this is a higher-risk, more interesting Sunda than the one investors had a year ago. The 2025 numbers alone are weak, but the shape of the business is improving. If the New Zealand acquisition completes and Chuditch gets back onto a credible drilling timetable, the company starts to look a lot more investable.
Until then, this remains a story of potential rather than proof. For retail investors, that means keeping one eye on the upside and the other firmly on the cash balance.
