Deal terms and production capacity

Each Headwater share converts into one Tamarack common share, with Tamarack issuing 237.8 million new shares in total. Post-close, Tamarack investors will hold 66.5% of the merged group and Headwater investors 33.5%. Tamarack's current management will lead the combined company.

On a pro forma basis, the companies forecast 2026 production of 65,500 to 67,500 boepd, a 7% increase on Tamarack's prior guidance. Capital spending for 2026 is guided at C$450m to C$470m for the merged entity, while the two standalone programs are forecast at around C$700m combined for the full year. Available liquidity is expected to exceed C$1.2bn, anchored by an undrawn C$875m credit facility maturing in May 2030, with net cash projected above C$50m.

The transaction is expected to cut Tamarack's 2027 decline rate to 15% and lower its unhedged free funds flow breakeven to $37 per barrel. Free funds flow per share is projected to rise by more than 10%. The companies estimate run-rate cost savings above C$50m annually, or more than C$350m across the full development plan. The merged entity's proved and probable reserve base is expected to exceed 300 million barrels of oil equivalent, with over 3,000 identified drilling locations across the fairway.

Non-core exploration assets will be carved out into a newly formed entity called Tributary Exploration. Those assets include Mannville-stack rights in Alberta, thermal heavy oil prospects at Handel in Saskatchewan, and legacy McCully gas production in New Brunswick. Current Headwater management, including Neil Roszell as executive chair and Jason Jaskela as president and CEO, will lead Tributary.

What to watch

The deal now heads to shareholder and court votes, with Competition Act review and TSX approval also required before closing. The shareholder vote timetable is the next concrete filing to track.
