ONEOK has agreed to acquire Brazos Midstream’s natural gas gathering and processing assets in the Permian Midland Basin for about $4.43 billion, a move that substantially expands the company’s footprint where U.S. oil and gas output remains strong. The deal, announced Sunday, signals how rising gas flows and record liquefied natural gas shipments are reshaping pipeline operators’ strategies and is expected to close in the fourth quarter of 2026.
By adding the Brazos Midland portfolio, ONEOK will roughly double its processing capacity in the Permian, positioning the Tulsa-based pipeline operator to capture higher volumes from the prolific basin. Company executives said the acquisition will be immediately accretive to earnings per share and to free cash flow once the transaction is complete.

How the purchase is being financed
Financing for the acquisition is being led by an equity commitment from Apollo Global Management. Apollo and its affiliates will supply a substantial non-voting minority stake that will be placed into a newly created holding vehicle.

| Element | Details |
|---|---|
| Purchase price | $4.43 billion |
| Lead investor | Apollo Global Management — $9.0 billion non-voting minority equity |
| Holding vehicle | ONEOK Holdings, L.L.C. (Class B interest to Apollo) |
| Use of proceeds | Fund acquisition and retire roughly $5.0 billion of existing debt |
| Expected close | Q4 2026 |
ONEOK’s existing Permian platform already serves major producers, and the added assets will strengthen ties with operators running active rigs in the region. Companies operating in the area include industry names such as ExxonMobil, Diamondback Energy and Double Eagle.
What this means for markets and customers
The acquisition responds to a simple market fact: the Permian continues to produce abundant gas alongside crude, and U.S. LNG exports have pushed domestic demand for pipeline capacity higher. For ONEOK, the transaction is both a growth and a balance-sheet play.
- Near-term impact: Immediate boost to EPS and free cash flow, according to company guidance.
- Operational effect: Significant increase in processing capacity within ONEOK’s Permian operations.
- Financial posture: Use of Apollo’s equity lets ONEOK both pay for the assets and pare down roughly $5 billion of existing debt.
Analysts will watch how quickly the acquired midstream systems are integrated and whether the financing structure—heavy on non-voting minority equity—affects ONEOK’s long-term leverage and capital allocation. The structure keeps operating control with ONEOK while giving Apollo an economic interest in the assets.
For energy market participants and local producers, the deal could translate into smoother access to processing capacity and additional takeaway options as Permian production remains high. For investors, the combination of asset growth and debt reduction will be evaluated against prevailing commodity prices and capital markets conditions.
Regulatory clearance and the customary closing conditions will determine the final timetable, but the agreement highlights the continued consolidation and capital shifts underway across the U.S. midstream sector as companies reposition for rising gas flows and international demand for LNG.
