ONEOK’s $4.4 Billion Permian Acquisition Funded by Apollo’s $9 Billion Minority Equity Deal
9/1/2026, 10:57:28 AM
Core Transaction Overview
On August 30, 2026, ONEOK Inc. announced a definitive agreement to buy Brazos Midstream’s natural-gas gathering and processing assets in the Permian Midland Basin for approximately $4.425 billion in cash. The purchase adds roughly 700 miles of gathering pipelines and 1.2 Bcf/d of processing capacity, more than doubling ONEOK’s Midland-Basin capacity to about 2.3 Bcf/d once the Cassidy II plant is completed in Q3 2027.
Financing comes from a $9 billion non-voting minority equity investment by Apollo Global Management funds. ONEOK will use about $5 billion of the proceeds to retire debt, targeting a pro-forma 2027 leverage ratio of ~3.25 × debt-to-EBITDA without issuing new common equity.
Background & Context
The Permian Basin now supplies roughly 23 % of U.S. natural-gas output. Rising LNG exports and data-center electricity demand have increased the value of midstream infrastructure. ONEOK’s deal follows a $1.6 billion Western Midstream acquisition in June 2026.
Data & Statistics
| Metric | Figure |
|---|---|
| Purchase price | $4.425 billion (cash) |
| Apollo equity investment | $9 billion (Class B) |
| Debt to be retired | ~$5 billion |
| Gathering infrastructure | ~700 miles |
| Processing capacity (post-Cassidy II) | 1.2 Bcf/d |
| Combined Midland capacity | ~2.3 Bcf/d |
| EBITDA multiple (2027) | ~7.5 × (including $80 million synergies) |
| Expected 2027 leverage | ~3.25 × debt-to-EBITDA |
Official Statements & Responses
- ONEOK’s president and CEO Pierce H. Norton said the assets add a “premier Permian Midland Basin platform supported by long-term contracts and attractive growth opportunities.”
- Apollo partner Jamshid Ehsani called the investment a “flexible capital solution” that provides a Class B interest in a new holding company subordinate to senior debt.
ONEOK will treat the Apollo investment as permanent equity, reporting it as a non-controlling interest under GAAP and receiving full equity credit from rating agencies. The board approved both the acquisition and the Apollo investment; the transaction remains subject to customary closing conditions and antitrust clearance.
Why It Matters
The deal creates one of the largest integrated natural-gas gathering-processing platforms in the Permian, reinforcing ONEOK’s “wellhead-to-water” strategy and enhancing connectivity to its downstream NGL pipelines. By using structured equity rather than new common stock, ONEOK preserves shareholder equity while accelerating deleveraging. The expanded capacity positions the company to capture volume growth from producers such as ExxonMobil, Diamondback Energy, and Double Eagle, and to support rising domestic LNG feedstock needs.
Conflicting Reports & Gaps
- Purchase price reports vary slightly ($4.425 billion vs. $4.43 billion); ONEOK’s release cites $4.425 billion.
- The $9 billion Apollo investment and $5 billion debt-extinguishment have not yet been confirmed by an independent SEC filing.
- Details of the Class B cash-flow distribution and IRR caps lack external verification.
Timeline
- August 30 2026 – ONEOK announces agreement to acquire Brazos Midstream assets.
- Q4 2026 – Expected closing of the acquisition, pending regulatory clearance.
- Early Sept 2026 – Anticipated closing of Apollo’s minority equity investment.
- Q3 2027 – Completion of the Cassidy II processing plant, enabling full 1.2 Bcf/d capacity.
What’s Next
- Closing will trigger debt repayments and the projected leverage reduction.
- Integration of the Brazos system with ONEOK’s existing Midland assets and downstream infrastructure will begin immediately after closing.
- Management will monitor natural-gas and NGL pricing, as well as Permian production growth, to assess earnings accretion and cash-flow benefits.
