Jadestone Energy

@JadestoneEnergy announces an operational update. Key points: · Following the resumption of production at CWLH, Group production has risen to ~19,000 boepd (excluding Stag which remains offline). 2026 Group production guidance of 16-18,000 boepd is unchanged. · CWLH - production resumed, with the field producing ~8,000 bopd gross (~2,700 bopd net) in recent days. The operator is evaluating options to safely restore production from the final production well at the earliest possible opportunity. · Vietnam - Jadestone is in the final stages of discussions with a select list of counterparties for the Nam Du/U Minh project farm-out. In parallel, the key development contracts for the project are also nearing completion. Jadestone continues to target a final investment decision before the end of 2026. · Montara - since a return to stable operations following the successful re-injection compressor upgrade earlier in 2026, Montara has been Jadestone’s highest reliability asset, averaging ~97% uptime. A ~300kbbls cargo of Montara crude was lifted in early October, with a realised price of ~US$133/bbl.

@JadestoneEnergy announces that it has received formal notification from PT Prima Petroleum Enerji (“Prima Energy”) that Prima Energy has acquired 154,094,444 ordinary shares in Jadestone, representing approximately 28.3% of the Company's issued share capital. The shares were acquired from funds managed by Tyrus Capital S.A.M. (“Tyrus”). As a result, Tyrus no longer holds any ordinary shares in Jadestone. The Sale was bilaterally arranged between Tyrus and Prima Energy. The Company received no proceeds from the Sale. There is no change to the Company's issued share capital, with 544,936,979 shares currently in issue. Dr. Adel Chaouch, Executive Chairman of Jadestone, commented: “Tyrus was a significant shareholder in Jadestone for over a decade, and the Company would not have established itself as a leading independent in the Asia-Pacific region without Tyrus’ support and engagement. We thank the Tyrus team and wish them well in the future. We are pleased to see the sale of Tyrus’ holding completed at what we understand to be a very substantial premium to the average share price over the last month. It is a clear endorsement of the value in our Asia-Pacific platform and assets by a notable regional strategic investor, and we look forward to engaging constructively with Prima Energy to deliver on our strategic objectives. Since I joined Jadestone and with the efforts of a refreshed and revitalised management team, we have deepened and strengthened our relationships with the national oil companies, regulators and contractors in our core jurisdictions in Asia-Pacific. The significant progress we have made this year on commercialising our Vietnam gas discoveries is clear evidence of strategic delivery for our shareholders. We look forward to redoubling those efforts to deliver further value and benefits for all stakeholders over the coming months and years.” The full announcement can be read at: jadestone-energy.com/change-… $JSE #JSE #Jadestone #oilandgas

@JadestoneEnergy announces first-half 2026 results. Key points: · All guidance metrics unchanged · On track to take final investment decision on the Vietnam Nam Du/U Minh development by the end of 2026, with the farm-out process progressing to final negotiations with a select short list of interested counterparties. · Resumption of production at CWLH still targeted for around the end of Q3 2026 · Resumption of production at Stag still targeted for Q2 2027 T. Mitch Little, Chief Executive Officer of Jadestone, commented: “With the first half of 2026 now in the rear-view mirror, I am pleased with the progress we’ve made on bolstering the foundations of our underlying business. We have enhanced the financial strength of the platform through our debt refinancing, delivered material progress on our key Vietnam growth project, and delivered a very successful infill drilling program offshore Malaysia. More broadly, we are beginning to see signs of the hard work our teams are doing to instill operational excellence across the operated portfolio. While I recognize we need to demonstrate sustainable long-term performance before declaring full success, it’s encouraging to see that our collective focus is beginning to translate into a stronger and more resilient business. Most notably, we are seeing meaningful improvements in operating performance at Montara. We have also delivered the Malaysia drilling program more than 20% below budget, while setting drilling records in the process. Both examples provide concrete evidence of the operational standards we are working to embed across the entire business. Notwithstanding the positive momentum in the business, our performance in the first half was affected by two key external events, a delayed production restart at CWLH following the dry dock maintenance campaign, and the impact of Cyclone Narelle on our operated Stag field. These events, combined with the sale of our Thailand assets in April 2025, represent the bulk of the period-on-period production decline in the first half. We now have defined plans in place to reinstate production at both CWLH and Stag. Looking ahead, we remain focused on maintaining our positive operational momentum while progressing the next phase of growth. In Vietnam, we remain on track to take final investment decision on the Nam Du/U Minh development by the end of 2026, with the farm-out process progressing to final negotiations with a select short list of interested counterparties.” Read the full release here: jadestone-energy.com/2026-ha… Webcast at 9:00 a.m. BST today, details of which can be found in the statement. $JSE #JSE #Jadestone #oilandgas

@JadestoneEnergy issues a trading statement for the half-year ended 30 June 2026. Key points: · Sustained positive momentum on the Nam Du/U Minh development, with FDP approval, GSPA signature, an ongoing farm-out process, and substantial progress towards contract awards for the key field infrastructure. · On track to conclude the farm-out process and formally sanction the initial phase of the project before year-end. · Third well in the Malaysia drilling campaign was successful, flowing at ~2,500 bopd. All three wells are currently online and were delivered at an overall cost of over 20% below expectations. The East Belumut field is currently producing at a gross rate of ~12 kbopd, or over 3x the rate prior to commencement of the drilling. · While Jadestone has successfully executed on the business drivers within its control, external factors have impacted first half Group production. The combined impacts of Cyclone Narelle’s damage to the CALM buoy at Stag and the delayed restart of production at CWLH result in revised 2026 production guidance. · The impact on guidance is partly mitigated by the strong performance elsewhere in Jadestone’s diversified portfolio. In addition, the ongoing costs of remediation efforts at Stag are underpinned by the Group’s insurance coverage. · Current focus on safely restoring Group output to its current potential of over 20,000 boepd, while also advancing organic and inorganic growth opportunities in parallel.

@JadestoneEnergy is pleased to announce that the second well in the 2026 Malaysia drilling campaign on the PM323 PSC (Jadestone 60% interest) has been successfully drilled 13% below budget and brought online at ~2,800 bopd. The well set a new Malaysia record in extreme reach drilling, further demonstrating Jadestone’s in-house drilling capability. As previously announced, the encouraging results of the first two wells in the 2026 drilling programme resulted in a decision to drill the third contingent well. Drilling and completion activities on the third well have recently been concluded, with results to be reported in due course. T. Mitch Little, Chief Executive Officer of Jadestone, commented: “Following on from the excellent results of the first well in the 2026 East Belumut campaign, the second well has delivered a similarly positive outcome. It sets a new record for extended reach drilling across all basins in Malaysia, a very impressive milestone by our drilling team. In aggregate, the first two wells have increased production from the field by over 150% (an increase of ~6,000 bopd) – further validating our proven capability to unlock reserves, and create value in existing fields, by identifying and executing on opportunities bypassed by previous operators. We look forward to updating the market on the third well in the near future." Read the full announcement at: jadestone-energy.com/second-… $JSE #JSE #Jadestone #oilandgas #Malaysia

@JadestoneEnergy is pleased to announce that the first well in the 2026 Malaysia drilling campaign on the PM323 PSC has been successfully drilled 20% below budget and brought online at ~3,000 bopd. The 2026 Malaysia drilling campaign originally included two firm wells and a third contingent well targeting the southwest extension of the East Belumut field, which was identified in the 2023 infill programme. Based on the strong performance of the first well and the subsurface data gathered during drilling of the second well, the third well has now been confirmed and drilling has commenced. The Group’s 2026 capital expenditure guidance of US$50-80 million remains unchanged. T. Mitch Little, Chief Executive Officer of Jadestone, commented: “Our established operating capabilities in Malaysia, combined with our refreshed focus on operational excellence, have been further validated by the outcome of the EBA-18ST3 well. The result is an excellent start to this year’s drilling campaign and will significantly increase our Malaysia production in the near-term against the backdrop of strengthened Brent oil prices, with our most recent Malaysia oil sales attracting a US$14/bbl premium to Brent. Following on from the significant progress on our Vietnam project earlier this year and the successful debt refinancing, this is further evidence of a business that is executing on its plan and strategy. We look forward to updating the market further on the second well in the campaign in the near-future.” Read the full release at: jadestone-energy.com/first-w… $JSE #JSE #Jadestone #oilandgas #Malaysia

Great to spend time with CEO Mitch Little and CFO Andrew Fairclough on the road in London this week following @JadestoneEnergy's full-year 2025 results announcement. In all meetings there was significant focus on Jadestone’s Nam Du/U Minh development project in Vietnam, particularly the material upside potential close to existing discoveries, which is set out in the slide below. We’ve made fantastic progress in Vietnam already this year with Field Development Plan approval and signature of the Gas Sales and Purchase Agreement. We are now pushing forward with finalising the tenders for the major contract awards. The farm-out process is underway with engagements commencing this past week. We're aiming to take Final Investment Decision on Nam Du/U Minh by the end of this year. Plenty of catalysts to look forward to over the remainder of 2026 on a project which believe can unlock significant shareholder value! $JSE #JSE #Jadestone #oilandgas #vietnam

@JadestoneEnergy reports full-year 2025 results. Key points: Guidance unchanged. Strengthened financial position, with pro-forma net debt of US$5 million and pro-forma liquidity of US$220 million at 30 April 2026 following the successful Nordic bond issue. Vietnam farm-out process has commenced – encouraged by the number and quality of interested parties to date. T. Mitch Little, Chief Executive Officer, commented: “Jadestone’s improved operational performance and cash flow generation in 2025 reflect the organization’s hard work and relentless focus on the operational excellence and cost discipline principles which have been instilled under the leadership of our refreshed management team. These results were also underpinned by another excellent year of HSE performance across the Group. However, our financial results were impacted by the previously disclosed impairment, which was the main driver of a loss after tax for the year. Protecting the base business will remain a key focus for the Group, as we work to return to sustainable profits and maximize cash generation to support our future growth ambitions. The strong momentum from 2025 continued into early 2026, where we have already delivered on several of our key near-term priorities for the year. In Vietnam, we achieved FDP approval and signature of the GSPA for the Nam Du/U Minh project, clearing the key regulatory and commercial milestones required for project execution. The farm-out process has now commenced, and we have been encouraged by both the number and quality of interested parties to date. Separately, we have refinanced our debt with the issuance of our debut bond, removing near-term debt repayments and allowing us to focus near-term cashflow on accretive growth opportunities. After excellent operating performance in the first quarter of 2026, where we delivered on plan against all key metrics, the second quarter has started with some operational headwinds, primarily associated with the effects of Cyclone Narelle, one of the strongest storms to pass through offshore Western Australia in recorded history. The full impact of the storm is still being assessed, but will likely result in the Stag field remaining offline until the fourth quarter of this year based on current information. The Okha FPSO has arrived back on station at the CWLH fields following its successful dry-dock. However, recent subsea inspections have established that some minor structural repairs may be required to one of the field’s subsea riser’s J tube before re-connecting the vessel to the Riser Turret Mooring. Recent events in the Middle East continue to highlight the strategic value of a diversified portfolio of upstream assets in the Asia-Pacific region – reinforcing our long-standing corporate strategy. We remain geared towards Brent oil price strength, seeing realized prices for our oil sales increase significantly in recent months, with a positive impact on our financial performance. Combined with the bond issue, our financial position has strengthened significantly since the beginning of the year.” Read the full announcement here: jadestone-energy.com/full-ye… $JSE #JSE #Jadestone #oilandgas

@JadestoneEnergy is very pleased to announce the signing of the Gas Sales and Purchase Agreement (“GSPA”) for the supply of gas from the Nam Du / U Minh discoveries offshore Vietnam. T. Mitch Little, Chief Executive Officer of Jadestone, commented: “The execution of this agreement is a pivotal moment for Jadestone. After years of dedicated effort, we are now in a position to deliver the Nam Du/U Minh development, which will materially strengthen our portfolio while supporting our growth ambitions. With all key commercial and technical approvals now in place, and recent key hires into the Jadestone Vietnam project delivery team, we are now focused on rapidly progressing towards the project execution phase. Our near-term priorities are to conclude the bid evaluation for the FPSO and field infrastructure, and award their respective contracts during the second half of this year. We thank all of our stakeholders in Vietnam for supporting the recent progress on Nam Du/U Minh, and we look forward to working with them to deliver the development safely and efficiently. Over the project life, we expect that the development and production phases will generate significant local employment opportunities, material contract awards to local Vietnam companies, and hundreds of millions of dollars in government revenues. The Nam Du/U Minh project also supports Vietnam’s strategic plan and net zero ambitions, prioritizing sovereign resources to enhance Vietnam’s energy security and economic growth alongside the transition to lower emitting sources of fuel.” Read the full release here: jadestone-energy.com/vietnam… $JSE #JSE #Jadestone #oilandgas #vietnam

@JadestoneEnergy is pleased to announce that it has successfully completed a US$200 million senior secured bond issue with maturity in 2031 and a coupon of 12%. The bond placement was materially oversubscribed and saw strong investor demand across Nordic and international markets. Dr. Adel Chaouch, Executive Chairman, commented: “We are pleased that our debut bond offering generated substantial demand from credit investors seeking exposure to the strong upstream growth story of the Asia-Pacific region. The Nordic Bond Issue will deliver a strong financial foundation for the business, and allow Jadestone to focus its near-term cash flow generation on growth opportunities, particularly as we seek to move our Vietnam development forward following the key recent milestone of field development plan approval.” Read the full announcement here: jadestone-energy.com/success… $JSE #JSE #Jadestone #oilandgas
