Sunda Energy Postpones Timor-Leste Drilling to 2026 Amid Operational Setbacks

Interim take: busy half-year ends with a frustrating delay

Sunda Energy’s H1 2025 update is all about Timor-Leste. The company pushed hard to get the Chuditch-2 appraisal well off the ground in Q3 2025, but logistics tripped it up. A lack of compliant helicopter services meant no rig contract could be signed and, with that, the farm-in from state partner TIMOR GAP fell away. Drilling is now targeted for H1 2026.

There is progress in the background – permitting work, a 12‑month licence extension and fresh helicopter proposals – but the funding and timetable reset are the big takeaways for investors.

Chuditch PSC: large gas target with a clear appraisal plan

Chuditch sits offshore Timor-Leste in 40‑120m water, roughly 185km south of the country and near established fields. Shell’s 1998 Chuditch‑1 well found a 30m gross gas column in Jurassic Plover sandstones. Sunda’s reprocessed 3D seismic indicates a structure more than 20km long with around 150m vertical relief and a Pmean Contingent Resource of 1.16 Tcf of gas.

The planned Chuditch‑2 location is 5.1km from the discovery, in 68m water, where the company predicts a 149m gas column in the same reservoirs. In January 2025, Sunda completed the Environmental Baseline Survey and has integrated the results into the Environmental Impact Statement and Environmental Management Plan for the drilling permit.

Why the well slipped to 2026: helicopters, approvals and knock-on effects

The company could not secure helicopter support meeting “operational objectives and safety standards” at the required time, and alternative international providers were not approved. Without choppers, no rig – and without a rig contract, the April 2025 farm‑in with TIMOR GAP terminated automatically.

Post-termination, equity on the PSC reverts to Sunda 60% and TIMOR GAP 40%, with costs split 80%/20%. ANP granted a 12‑month extension to Contract Year 3 to 18 June 2026 and drilling is now slated for H1 2026. Revised proposals from the Timor‑Leste helicopter company “appear broadly acceptable”, rig discussions are active and the Environmental Permit is expected “in the near future”. Constructive talks with TIMOR GAP on funding and operations are ongoing.

Funding shuffle: CLN in, instant conversion, big dilution and warrants

In April, Sunda paired the TIMOR GAP farm‑in with unsecured Convertible Loan Notes (CLNs) of up to US$9.0 million to fund Chuditch‑2. Only the first US$1.5 million (£1.135 million) was issued on 12 May. Four days later, noteholders converted the lot into equity at 0.03995p, resulting in 3,125,594,493 new shares and the issue of 1,803,227,592 warrants exercisable at 0.051935p for three years.

The warrants are accounted for as a financial liability – initially £360,000, marked down by £252,000 at period end, leaving £108,000 on the balance sheet and a non‑cash gain in the income statement. The swift conversion cleaned up debt but came with heavy dilution and overhang potential from a large warrant stack.

Financials: slim cash, controlled spend, going concern flagged

The group reported a net loss of £1.13 million for the half (H1 2024: £0.91 million). Administration expenses were £1.09 million, including £485,000 of legal and professional fees and £173,000 of share‑based payments, partly offset by £260,000 of farm‑out cost recoveries.

Cash at 30 June 2025 stood at £976,000, excluding the performance bond deposit of £1.458 million. Intangible exploration assets increased to £6.685 million as work progressed at Chuditch. The company highlights a “material uncertainty” on going concern: additional funding is assumed to cover Sunda’s share of drilling and overheads through to 31 August 2026. Directors are confident about raising funds, but there is no certainty.

Strategic optionality: Timor-Leste first, Philippines next, plus other new ventures

The Philippines remains a potential second leg. Sunda’s applications for two BARMM blocks in the Sulu Sea await final Presidential signature. The areas include several gas discoveries and multiple drilling targets, but timelines are not disclosed. Management also notes pursuit of “material” new business initiatives to diversify and scale the portfolio – details to follow if they land.

What this means for investors: the good, the bad and the catalysts

Positives

• Resource scale is attractive: 1.16 Tcf Pmean with a clear appraisal case at Chuditch‑2.
• Regulatory momentum: Environmental work completed, permit expected near term, and a 12‑month licence extension secured to mid‑2026.
• Operational path emerging: revised helicopter solution looks acceptable; rig discussions active.
• Balance sheet clarity: CLN converted quickly, removing short‑term debt and adding a non‑cash gain from warrant revaluation.

Watch-outs

• Funding risk: cash of £976,000 means fresh capital is needed to meet Sunda’s 80% cost share for Chuditch‑2 and to cover corporate overheads.
• Dilution and overhang: 3.13 billion new shares plus 1.80 billion warrants at 0.051935p.
• Execution risk in-country: helicopter approvals, rig contracting and final permitting must all line up for an H1 2026 spud.
• Farm-in setback: losing the April 2025 deal removed a near‑term cost carry and shifted more spend back to Sunda.

Upcoming catalysts to track through H2 2025 and early 2026

• Environmental Permit issuance for Chuditch‑2.
• Helicopter services contract and rig award.
• Funding package – equity, partner contribution or another structure.
• Update on discussions with TIMOR GAP regarding operational and funding plans.
• Decision on the two BARMM blocks in the Philippines.

My view: higher-risk reset, still anchored by a sizable gas target

This is a classic frontier appraisal story. The asset remains compelling on paper and the regulatory pieces are moving, but the slip to 2026 and farm‑in termination reset the risk profile. With only £976,000 of cash, Sunda needs to secure funding and logistics quickly to keep the timetable intact.

If the company lands the helicopter and rig contracts, nails the permit and brings in the right capital/partner mix, the H1 2026 well can be a major value event. Until then, expect the shares to trade on progress milestones and funding news. For investors comfortable with exploration risk and timing uncertainty, Chuditch’s 1.16 Tcf Pmean keeps the upside firmly on the table – but the near‑term story is about execution and finance.
