Consolidation and delivery dominated the sector's news flow, with a takeover battle over Capricorn Energy sharpening as DNO tabled a richer all-cash offer, while smaller producers Arrow Exploration and Empyrean Energy reported hard progress on reserves growth and project execution respectively.
DNO sweetens Capricorn cash takeover bid
Capricorn Energy (LSE:CNE), the Scotland-incorporated oil and gas company trading at 383.0p and largely unmoved on the day at -0.26%, confirmed a revised recommended cash offer from Norway's DNO that lifts the total value delivered to shareholders to $5.214 per share, up from $4.224. The improved terms, equivalent to 388p, represent a 46% premium to Capricorn's undisturbed closing price of 266p on 10 March and a 61% premium to the three-month volume-weighted average price to that date, and crucially, they now top the rival cash offer from Genel Bidco announced on 2 July by roughly 10%.
The mechanics of the sweetener matter as much as the headline number. Under the original offer announced on 1 September, Capricorn shareholders were to receive $4.224 in cash plus a $0.99 special dividend, contingent on the board being able to declare and pay that dividend before completion. The revised offer instead delivers the full $5.214 per share in cash directly from DNO's bid vehicle, stripping out that conditionality and valuing Capricorn's fully diluted share capital at approximately $396 million, or £294 million. Capricorn's board, advised by Canaccord Genuity, has called the new terms fair and reasonable and intends to recommend the scheme unanimously.
"Arrow has been successful in the M&A front, adding reserves accretively," said Marshall Abbott, Chief Executive.
The revised bid effectively forces Genel Bidco's hand: its competing offer is now formally inferior by $0.474 per share, and without a counter-raise its path to winning shareholder support narrows considerably. By removing the dividend-timing risk that shadowed the original DNO proposal, the Norwegian bidder has closed off the main argument shareholders might have had for holding out, strengthening its position to see the deal through to completion on the terms now on the table.
Arrow Exploration lifts 2P oil reserves 82% at mid-year
Arrow Exploration (AIM:AXL), the Colombia and Canada-focused oil and gas producer trading at 29.35p, down 2.17% on the day, reported that proved plus probable (2P) reserves rose 82% to 21.4 million barrels of oil equivalent against year-end 2025, according to a mid-year 2026 reserves report from Boury Global Energy Consultants. Those 2P reserves are valued at $410 million on a before-tax net present value basis discounted at 10%, while proved developed producing reserves climbed 62% to 2.9 MMboe, worth $59.3 million, and proved (1P) reserves more than doubled, up 110% to 11.4 MMboe.
The gains trace principally to the Icaco discovery in Colombia's Llanos Basin, made in the second quarter, alongside the acquisition of the Thorsby asset in Alberta. Six wells have been drilled at Icaco so far, three producing from the Carbonera formation and two from the Ubaque formation, with a further five wells planned. Three-plus reserves (2P plus possible) climbed 71% to 34.4 MMboe, valued at $731 million, underlining the scale of the resource base now being booked. "Arrow has been successful in the M&A front, adding reserves accretively," said Marshall Abbott, Chief Executive.
The scale of the uplift, reserves nearly doubling in under a year, reframes Arrow's investment case roughly organic exploration success rather than pure production growth, with Icaco emerging as the company's most material asset. The Thorsby acquisition adds diversification beyond Colombia, giving the company two independent growth levers into next year's drilling campaign.
Empyrean says Mako gas project stays on budget for 2027 start
Empyrean Energy (AIM:EME), up 4.082% to 0.051p, confirmed that the Mako Gas Project in Indonesia's Duyung PSC remains on budget and on schedule for first gas in the fourth quarter of 2027. Operator Conrad Asia Energy and its subsidiary West Natuna Exploration reaffirmed the timeline, with Empyrean entitled to 8.5% of all cash payments to WNEL, including Mako gas sales revenue, subject to documentation flagged in its 10 September announcement.
Physical progress on the project is advancing in parallel with the financial confirmation. The donor jack-up rig Valaris 104, destined for conversion into the Mobile Offshore Production Unit, has been wet-towed through the Strait of Hormuz and loaded for transport to Batam, with arrival expected by the end of the third quarter. Factory acceptance testing of the compression system's key motors is complete in Germany, shipment to Batam is due early in the fourth quarter, and fabrication at the PaxOcean Yard is set to begin before the end of September, with contracts now signed covering 90% of project capital spend. "The project remains on budget and on track for first gas in the fourth quarter of 2027," said Empyrean's CEO.
With 90% of capital spend now contractually locked in, the project has passed a key de-risking milestone, reducing the scope for cost overruns to disrupt Empyrean's royalty-like entitlement to Mako revenues. For a company of Empyrean's size, this level of execution certainty on a multi-year infrastructure build is the clearest signal yet that the 2027 first-gas target is more than an operator's aspiration.
