ONEOK has signed a definitive agreement to buy Brazos Midstream’s Permian Midland Basin natural gas gathering and processing assets for total cash consideration of $4.425 billion. Reuters and most wires rounded it to $4.43 billion. On the operating numbers it is a clean, unexciting midstream bolt-on.
The financing is the part worth reading twice. ONEOK is funding the purchase out of a $9 billion nonvoting minority equity investment from funds and affiliates managed by Apollo — more than double the price of the thing being bought. ONEOK says it intends to use $5 billion of those proceeds to reduce existing indebtedness.
Do the arithmetic and the shape of the deal changes. Set aside the $5 billion for debt paydown and roughly $4 billion of the Apollo money is left against a $4.425 billion purchase price. The acquisition is not really what the $9 billion is for. It is the occasion for it.
What ONEOK actually gets
The assets more than double ONEOK’s Midland Basin processing capacity to roughly 2.3 Bcf/d, counting facilities still under construction. They come with about 600,000 dedicated acres on long-term fixed-fee contracts with a weighted average remaining term of more than 12 years — which is the detail that makes the cash flow financeable rather than commodity-exposed.
ONEOK puts the multiple at approximately 7.5 times estimated 2027 EBITDA including about $80 million of full-year synergies, falling to roughly 6.0 times on 2028 estimates. It expects the deal to be immediately accretive to earnings and free cash flow per share, and to close in the fourth quarter of 2026 subject to Hart-Scott-Rodino clearance.
The structure is the story
A nonvoting minority equity investment is a specific instrument doing a specific job. Apollo gets economics without governance: no votes, no control, no board seat trading on the outcome. ONEOK gets capital that sits in the equity line rather than the debt stack, carries no coupon and trips no covenant — and it immediately uses over half of it to retire borrowings that did both.
Our take: This is a balance sheet trade dressed as an acquisition. The cheapest capital available to a large-cap in 2026 is not a loan, it is equity from a private manager willing to give up every governance right in exchange for the economics. That is a genuinely good deal for the issuer today. It is also permanent dilution that no future shareholder gets to vote away, sold at a moment when the alternative — rated debt at current long-end yields — looks expensive. Watch whether the ratings agencies agree it is equity.
Note who is on the other side of the week. Apollo has just sold Kelvion to SLB in a deal worth about $4.1 billion including assumed debt, and is now writing a $9 billion cheque into ONEOK. Seller in one, financier in the other, inside the same 48 hours. Private capital is no longer choosing between owning assets and lending against them. It is doing both, and increasingly it is the counterparty on whichever side of the table has the better terms.
What to watch
- HSR clearance and the Q4 close. Midstream consolidation in a single basin invites a longer look than the parties have assumed.
- How the rating agencies treat the Apollo instrument. If it is scored as debt-like rather than equity, the $5 billion paydown buys less headroom than the press release implies.
- The $80 million synergy number. It is doing real work in the 7.5x multiple. It should be visible in 2027 results or it was never there.
- Copycats. If this structure clears cleanly, expect other capital-hungry infrastructure names to run the same play before the window shuts.
