Tamarack Valley and Headwater Exploration Agree to $10B Clearwater Oil Merger

Tamarack expects 2026 pro forma production of 65,500 to 67,500 barrels of oil equivalent per day, before the merged company reaches its projected run-rate production above 80,000 boe per day.
Tamarack President Steve Buytels is scheduled to become CEO and join the combined company’s board on Jan. 1, 2027, while founding CEO Brian Schmidt will become executive chairman.
The companies say the merger will produce more than C$50 million in annual run-rate synergies and increase Tamarack’s free funds flow per share by more than 10%.
The combined company is expected to have more than C$50 million in net cash and over C$1.2 billion in available funding, including a fully undrawn C$875 million credit facility.
Tributary Exploration’s assets will include Mannville-stack exploratory mineral rights in Alberta, thermal heavy-oil prospects at Handel in Saskatchewan and legacy McCully natural-gas production in New Brunswick; Tributary plans to raise up to C$30 million through a non-brokered placement after closing.
Tamarack Valley Energy and Headwater Exploration have agreed to merge in an all-stock deal valued at C$10 billion (about $7.24 billion USD), according to Financial Post. The combined company will become a major Alberta oil producer, churning out more than 80,000 barrels of oil equivalent per day with over 300 million barrels of proved reserves. Headwater shareholders get one Tamarack share for each share they own, leaving Tamarack investors with 66.5% of the merged business and Headwater investors with 33.5%.
The deal is expected to close in the fourth quarter of 2026, pending shareholder votes and regulatory approvals. The Deep Dive reports that Tamarack will raise its quarterly dividend by 20% and plans to spin off non-core exploration assets into a new publicly listed company called Tributary Exploration. The merged firm expects to generate more than C$50 million in annual synergies and boost free cash flow per share by over 10%.
In the all-stock transaction, each Headwater share converts into one Tamarack share. This structure gives Tamarack's current investors control of about two-thirds of the combined company while Headwater investors own roughly one-third. EnergyNow notes that the deal brings together the two largest operators in Alberta's Clearwater region, a massive oil-rich formation that both companies have been developing aggressively.
The merged company will produce 65,500 to 67,500 barrels of oil equivalent per day in 2026, climbing to more than 80,000 boe per day at full run-rate production, according to Offshore Technology. It will hold over 300 million barrels of proved and probable reserves and control more than 3,000 drilling locations. The combined firm expects to carry more than C$50 million in net cash and have access to over C$1.2 billion in available funding, including an undrawn C$875 million credit facility.
The merger is projected to generate more than C$50 million in annual run-rate synergies — cost savings from eliminating duplicate operations and combining purchasing power. Free cash flow per share is expected to jump by more than 10%. Tamarack will also increase its quarterly dividend by 20%, rewarding shareholders with higher payouts.
Tamarack's current President Steve Buytels will become CEO of the merged company and join its board on January 1, 2027. Founding CEO Brian Schmidt will step into the executive chairman role. Financial Post reports that non-core exploration assets will be separated into a newly listed public company called Tributary Exploration, which will be led by Headwater's current management team.
Tributary Exploration will inherit Mannville-stack exploratory rights in Alberta, thermal heavy-oil prospects at Handel in Saskatchewan, and legacy natural-gas production at McCully in New Brunswick. The spinoff company plans to raise up to C$30 million through a non-brokered placement after the merger closes. This structure allows investors to bet on the core Clearwater business or the riskier exploration upside separately.
The merger requires approval from both companies' shareholders, Canadian courts, competition regulators under the Competition Act, and the Toronto Stock Exchange. Offshore Technology says the deal is targeted to close in the fourth quarter of 2026, meaning roughly 18 months of regulatory review and shareholder voting lie ahead. The all-stock structure eliminates financing risk — no cash is needed to complete the transaction.
