Westmount Energy Limited
Westmount Energy Limited is a Jersey-incorporated public company, registered under the Companies (Jersey) Law 1991 with registration number 53623 and an incorporation date of 1 October 1992. Its registered office is at Floor 4, Liberation House, Castle Street, St Helier, Jersey, JE1 4HH. Westmount Energy Limited has traded on the AIM market of the London Stock Exchange since 2 October 1995 under the ticker WTE (ISIN GB00B0S5KR31), with Cavendish acting as its Nominated Adviser. An attempt to verify the company’s registry status directly through the Jersey Financial Services Commission’s online company search returned an access-denied response at the time of this profile’s research, an access limitation this registry has been found to present before rather than evidence of any change in status; Westmount Energy Limited’s continuing status is instead corroborated by its ongoing AIM admission and its regular regulatory filings, most recently an interim results announcement for the six months to 31 December 2025, published 30 March 2026.
Westmount Energy Limited describes its business as investing in, and providing follow-on capital to, small and medium-sized companies with significant growth potential in the upstream oil and gas sector; it is not, as of this profile’s research date, a clean-energy or renewable-energy investor, notwithstanding its earlier association with clean-technology holdings. As at 31 December 2025 its investment portfolio was carried at a market value of approximately £4.02 million and comprised minority equity interests in four exploration companies: JHI Associates Inc. (approximately 6.24%), which holds a 35% interest in Production Licence PL001 in the North Falkland Basin following a 2025 farm-in by Navitas Petroleum; Cataleya Energy Corporation (approximately 4.13%), with an interest in the Kaieteur Block offshore Guyana; Eco (Atlantic) Oil and Gas Ltd (approximately 0.43%), an AIM- and TSX-V-listed explorer holding interests in the Orinduik Block offshore Guyana and the Block 3B/4B licence offshore South Africa; and Ratio Petroleum Energy – Limited Partnership (approximately 0.04%), listed on the Tel Aviv Stock Exchange, with interests in the Kaieteur Block and Block 47 offshore Suriname. In June 2025 Westmount Energy Limited sold its entire 300,000-share holding in Meren Energy Inc. (formerly Africa Oil Corp.) for net proceeds of £286,155.
In an RNS announcement dated 19 May 2026, Westmount Energy Limited confirmed that JHI Associates Inc. shareholders had approved a proposed acquisition of JHI by Eco (Atlantic) Oil and Gas Ltd, valuing JHI at approximately £62.2 million, and that it had voted its own JHI shares in favour; on completion, Westmount Energy Limited expects to hold 9,527,432 common shares in Eco (Atlantic) Oil and Gas Ltd, combining shares received in exchange for its JHI holding with an additional conditional share purchase. As of that announcement, completion remained subject to a Falkland Islands Government licence-extension consent and to TSX-V and AIM regulatory approvals, and had not yet occurred. For the six months ended 31 December 2025, Westmount Energy Limited reported total equity of £4.15 million, a profit before tax of £202,779 (against a loss of £230,266 in the equivalent prior period), cash of £0.22 million and no debt.

Data availability
Shareholder information for Westmount Energy Limited is Major shareholders only: Jersey’s companies registry does not publish a public shareholder register, and the Jersey Financial Services Commission’s online company search returned an access-denied response when checked for this profile, an access limitation this registry has been found to present before. Disclosure instead comes through AIM/DTR major-holding notifications, which capture only holders crossing the applicable disclosure threshold, and through director shareholdings published in the annual report; the remaining shareholder base among the company’s approximately 1,000 holders of record is not itemised. No complete, dated ownership chain is available to calculate an ultimate beneficial owner, and no disclosed individual holding meets a recognised UBO control threshold, so no ultimate beneficial owner is identified in this profile.
