Background

Frontera Energy Corporation (TSX: FEC), a publicly listed Canadian holding company with upstream oil and gas operations in Colombia, has become the center of a contested acquisition battle — with two well-capitalized independent operators each making a case for why they are the better buyer for Frontera's Colombian E&P assets.

The assets in question are held through Frontera Petroleum International Holdings B.V. ("Frontera International"), a subsidiary comprising 17 upstream blocks in Colombia across two core areas: the Llanos Basin and the Lower Magdalena Basin. The portfolio includes the large-scale Quifa field, the CPE-6, Guatiquia and Cubiro blocks in the Llanos, and the VIM-1 condensate and gas block in the Lower Magdalena. The transaction does not include Frontera Energy Corporation itself, its infrastructure assets, or its exploration interests in Guyana.

Round One: GeoPark Signs a Definitive Agreement

On January 29, 2026, GeoPark Limited (NYSE: GPRK) announced it had entered into a definitive agreement with Frontera Energy to acquire 100% of Frontera International for a cash purchase price of US$375 million, subject to customary closing adjustments, plus an additional contingent payment of US$25 million tied to the achievement of certain development milestones.

Under the terms of the GeoPark agreement, GeoPark would also assume Frontera Energy's existing debt obligations — specifically US$310 million in unsecured notes (7.875% coupon, maturing 2028) and US$79 million net outstanding under a prepayment facility. This implies an enterprise value of approximately US$600 million for the acquired assets.

The transaction would be funded through a combination of cash on hand and committed financing, including a prepayment facility with Vitol of up to US$500 million, with US$330 million committed. Notably, no equity issuance was contemplated.

The GeoPark-Frontera agreement was unanimously approved by the Boards of Directors of both companies, with support agreements entered into by Frontera Energy's directors, officers, and shareholders holding a majority of voting power. The agreement includes customary termination fees applicable in certain circumstances.

GeoPark's strategic rationale was compelling on paper. The company has decades of operating experience in Colombia, an existing Llanos Basin presence, and deep local technical expertise. Specific highlights cited by GeoPark included:

• Pro forma production exceeding 90,000 boepd by 2028, doubling its standalone 2028 outlook of 44,000–46,000 boepd
• Pro forma EBITDA of approximately US$950 million by 2028, versus a standalone outlook of US$490–520 million
• Immediate addition of approximately 99 mmboe of 1P reserves and 147 mmboe of 2P reserves, more than doubling GeoPark's consolidated reserve base
• Attractive entry metrics: EV/1P of ~US$6.10/boe, EV/2P of ~US$4.10/boe, and EV/2025E EBITDA of ~2.0x
• Expected run-rate synergies of US$30–50 million per year by 2027, sustained over approximately six years
• Pro forma 2026E net leverage of approximately 2.0x EBITDA at closing, declining to approximately 1.4x by 2028 and below 1.0x thereafter
• A reduction in cash breakeven of approximately US$8 per barrel at current strip prices

GeoPark CEO Felipe Bayon framed the deal as enabling a "full-field development approach" for assets like Quifa, with the ability to extend production plateaus, capture operating synergies, and reinvest efficiently — all while continuing to fund the company's growth program in Vaca Muerta, Argentina.

Round Two: Parex Submits a Competing Proposal

On February 23, 2026 — approximately 25 days after GeoPark's definitive agreement was announced — Parex Resources Inc. (TSX: PXT) submitted an unsolicited acquisition proposal directly to Frontera's Board of Directors.

Parex's offer: US$500 million in cash, plus assumption of debt, plus the same US$25 million contingent payment on substantially the same terms as the existing GeoPark agreement. This represents a US$125 million premium to GeoPark's cash consideration of US$375 million — a 33% headline premium on the cash purchase price.

Parex CEO Imad Mohsen stated directly that the company expects Frontera's Board to conclude the Parex proposal constitutes a "Superior Proposal" as defined under the existing GeoPark definitive agreement — the contractual threshold that would allow Frontera to engage with and potentially accept a competing bid.

Parex's strategic rationale is grounded in its existing Colombian footprint. The company is already one of the largest independent oil and gas operators in Colombia, headquartered in Calgary with operations based in Bogotá. Critically, Parex is already a partner on the VIM-1 block — one of the key assets in the Frontera International portfolio — giving it direct operational insight into Frontera's asset quality and personnel.

Parex argued that a combined entity would create the largest independent Colombian-focused energy company, with enhanced capital efficiency, stronger free cash flow, and a more resilient long-term platform. Unlike GeoPark — which operates across both Colombia and Argentina — Parex frames its offer as a pure Colombia-focused consolidation play, with no competing capital allocation demands from another country's development program.

Analyst Perspective: How to Think About This

This is a classic topping bid scenario in E&P M&A. GeoPark moved first, negotiated extensively (CEO Bayon referenced "extensive discussions over the past year"), secured board approval, and locked in committed financing. Parex responded with a larger cash number and positioned it publicly as a Superior Proposal — a deliberate legal and strategic maneuver designed to force Frontera's board to evaluate the competing offer under the terms of the existing agreement.

Several dynamics are worth noting:

On valuation: GeoPark's US$375 million cash price implies an EV/2P of approximately US$4.10/boe. Parex's US$500 million cash consideration, assuming the same debt assumption terms, implies a meaningfully higher EV/2P — likely in the US$5.00–5.50/boe range, though the precise EV depends on Parex's treatment of the existing debt. Neither figure has been independently verified by a third party in public disclosures reviewed here.

On strategic fit: Both acquirers have legitimate claims to strategic fit. GeoPark brings Llanos Basin operating experience and a full-field development thesis for Quifa. Parex brings existing VIM-1 partnership knowledge, a pure Colombia focus, and arguably fewer competing capital demands — no Vaca Muerta program to fund in parallel.

On financing: GeoPark has disclosed its financing structure in detail — Vitol prepayment facility, no equity. Parex has not yet disclosed its financing sources in the available public materials.

On process: The existence of termination fees in the GeoPark agreement means any transition to a Superior Proposal carries a cost. The outcome will depend on how Frontera's Board weighs the US$125 million premium against deal certainty, financing confidence, and the relative integration thesis of each bidder.

What is not yet known: Whether Frontera's Board will formally designate the Parex proposal a Superior Proposal, whether GeoPark will exercise any right to match, and the ultimate closing timeline. As of the date of this writing, no updated announcement from Frontera's Board has been made public.
