On September 9, 2026, Enbridge announced a $2.55 billion cash acquisition of Tallgrass Energy's crude oil transportation, storage, and marketing business from Blackstone-controlled Tallgrass, expected to close later this year subject to U.S. antitrust clearance. The deal is the second midstream bolt-on Enbridge has disclosed in two weeks, following the $600 million Salt Creek Midstream purchase on August 26, and it cements Enbridge's U.S. crude footprint from the Delaware Basin wellhead to the Gulf Coast export dock.
What makes the transaction more than a routine pipeline roll-up is the structure of the carve-out: Blackstone is keeping the natural gas and NGL assets and selling the crude. Both decisions are deliberate, and together they map where the smartest capital in midstream thinks the next decade's cash flows will — and will not — come from.
The Deal: 75% of Pony Express, Half the Powder River, and a Crude Marketing Book
- Cash consideration: $2.55 billion, all cash, subject to closing adjustments. No equity issued to the seller.
- Implied multiple: ~10–11x forward EV/EBITDA, per Enbridge's disclosure on the deal call.
- Pony Express Pipeline (75% interest acquired): 1,050-mile crude system, 460,000 bpd nameplate capacity, links Guernsey, Wyoming to Cushing, Oklahoma, with access to ~500,000 bpd of refining capacity along the route.
- Powder River Gateway (51% interest acquired): Two crude pipelines combining for 240,000 bpd of delivery capacity into Pony Express.
- Storage (8.4M barrels): Nine crude terminals tied into Pony Express, including a 60.3% non-operating interest in the Deeprock Crude Terminal at Cushing.
- Stanchion Energy: Tallgrass's crude oil marketing subsidiary, which optimizes throughput across the acquired footprint.
- PXP2 growth project (rolled in): ~$300M incremental capex, lifts Pony Express capacity to ~515,000 bpd by late 2027, adds to Enbridge's C$41B secured backlog at closing.
- Phillips 66 retains a 25% non-operating interest in Pony Express — the deal does not consolidate Phillips 66's stake.
Financing will be a hybrid: an equity offering will partially fund both the Tallgrass crude deal and the August 26 Salt Creek Midstream acquisition, with the balance from cash on hand and incremental debt. Enbridge reiterated its 4.5x–5.0x Debt-to-Adjusted-EBITDA leverage target and said 2026 adjusted EBITDA guidance (C$20.2B–C$20.8B) and DCF-per-share guidance (C$5.70–C$6.10) remain unchanged. Management described the funding approach as conservative, designed to \"preserve capacity for future growth.\"
Why 10–11x Is the Right Price — and Why Most Peers Trade Below It
On a TTM basis, the midstream cohort trades in a wide range: Enterprise Products Partners at ~11.1x EV/EBITDA, Energy Transfer at ~9.8x, ONEOK at ~11.9x, MPLX at ~11.7x, Phillips 66 at ~9.4x. Enbridge's own TTM multiple is ~12.4x. So Enbridge is paying right at the high end of the band, not a discount. The premium is earned three ways.

The Carve-Out Is the Real Story — Blackstone Kept the Gas
Tallgrass Energy is not exiting midstream. After the deal, Tallgrass — still owned by Blackstone Infrastructure Partners alongside minority investor GIC — retains the natural gas and NGL platform. That platform is the more interesting one in 2026 terms: roughly 6,500 miles of FERC-regulated gas transmission (led by the 1,698-mile Rockies Express Pipeline), 1,500+ miles of gas gathering, ~190 Bcf/d of combined processing capacity, and an open season running for a new Permian-to-REX pipeline targeting a late-2028 in-service date to capture the LNG and AI-power demand surge.
- Rockies Express Zone 3 is contracted at 2.6 Bcf/d with a weighted-average remaining contract life of 16 years — comparable in quality to Pony Express, but gas.
- Cheyenne Connector is fully subscribed at 600 MMcf/d from the DJ Basin, with expansion capacity available.
- Permian-to-REX proposal would give shippers a new Permian gas egress to multiple markets via REX — Tallgrass owns the pipe on both ends.
- Tallgrass also retains NGL transportation, processing, and the Stanchion natural gas marketing book alongside its crude marketing arm.
Enbridge's Crude Platform Now Spans the Continent
Strip the two deals together with Enbridge's existing footprint and the strategic shape of the acquisition becomes obvious: this completes a U.S. crude platform that goes wellhead-to-water.
| Segment | Asset | Capacity / scale | Stake |
|---|---|---|---|
| Permian gathering | Salt Creek (Orla, Wink North) + DCX | 420,000 bpd gathering, 320K dedicated acres, 10-yr avg contract | 100% / 50% JV |
| Permian long-haul | Gray Oak Pipeline | 900,000–1,100,000 bpd to Corpus Christi | 65% (operator) |
| Export | Enbridge Ingleside Energy Center | Largest U.S. crude export terminal | 100% |
| Rockies long-haul (new) | Pony Express | 460,000 bpd → 515,000 bpd by late 2027 (PXP2) | 75% (post-deal) |
| Rockies gathering (new) | Powder River Gateway | 240,000 bpd | 51% (post-deal) |
| Cushing storage (new) | Nine terminals, 8.4M bbl incl. Deeprock | — | Various (post-deal) |
| Cushing storage (existing) | Enbridge Cushing Terminal | 27M bbl — world's largest crude tank facility | 100% |
| Mid-Continent integration | Wrangler Pipeline (Aug 9, 2026) | Guernsey → Cushing via Platte/Express | 100% |
| Canadian anchor | Mainline system | 3,125-mile Edmonton → U.S. Midwest | 100% |
The Funding Math: $3.15B in Two Weeks, Leverage Held
Enbridge has committed roughly $3.15 billion in announced U.S. crude M&A in 14 trading days: $600M for Salt Creek Midstream (Aug 26) and $2.55B for Tallgrass crude (Sep 9). On a combined ~$250M run-rate EBITDA contribution (the deal implies ~$230–255M of forward EBITDA at 10–11x, plus Salt Creek's contribution), the deals sit comfortably inside Enbridge's C$10B–C$11B average annual growth-capex capacity. The C$41B secured backlog announced at Q2 2026 earnings explicitly absorbs both the Tallgrass closing balance and the $300M PXP2 expansion upon closing.

The equity-offering component matters because Enbridge reported net debt to adjusted EBITDA of 5.2x at June 30, 2026 — already at the top end of the 4.5x–5.0x target band. The market reaction on September 9 was modestly negative: ENB traded down ~2.2% intraday on the announcement, with analysts noting the equity dilution as the principal near-term overhang even though accretion math was favorable.
Short-Term: What Moves First
- Equity offering sizing: The market is waiting for the deal's equity-component disclosure. CIBC already upgraded ENB to Sector Outperform with a C$78 target on August 28, citing \"value-add from the Westcoast JV and a constructive outlook\" — so the bar for the deal to register as positive is a clear accretion per-share estimate and a debt/equity mix that keeps 2026 EPS guidance intact.
- HART-SCOTT-RODINO review: Closing later in 2026 is conditional on FTC clearance. Pony Express competes most directly with Bridger Pipeline (joint tariff) and with Energy Transfer's Bakken Pipeline system for Rockies-origin crude. The FTC will scrutinize whether 75% control of the dominant Guernsey-to-Cushing corridor creates shipper harm, particularly given Bridger's recently announced competing Guernsey project.
- Q3 2026 earnings (early November): First quarter in which management can quantify the deal's per-share contribution. Investors will look for explicit DCF/share accretion guidance tied to closing timing.
- Phillips 66's Pony Express stake: PSX holds the 25% non-operating interest. PSX's Midstream segment will continue to book its share of Pony Express EBITDA and tariff revenue; the change is one of counterparty rather than cash-flow economics.
Long-Term: The Strategic Read
Two non-obvious conclusions follow from this transaction and the gas/crude split it formalized.
- Enbridge is now the indispensable middleman for U.S. crude. From the Delaware Basin wellhead, Permian long-haul to the Gulf, Rockies long-haul to Cushing, and Cushing storage and export — Enbridge touches every link in the value chain except E&P. That vertical depth is hard to replicate organically; Enterprise Products competes at Cushing, Energy Transfer competes in the Bakken, but neither has Enbridge's full-stack position. The natural competitive response is asset swaps or further consolidation.
- Long-haul crude is now a yield asset, not a growth asset. The multiple paid (10–11x) and the deal structure (accretive but no change to guidance) imply Enbridge values this for cash flow that supports its 5.5%+ dividend, not for re-rating. The growth in the U.S. midstream complex has migrated to gas infrastructure tied to LNG and power demand — which is why Blackstone kept that side.
What Investors Should Watch
Three named milestones will determine whether this deal pays off for Enbridge shareholders over the next 18 months: the size and pricing of the equity component (which sets the dilution math), the FTC clearance timeline (which sets the closing accretion clock), and the first quarter of consolidated contribution in Q3 2026 earnings. Beyond the deal itself, the strategic prize is the integrated platform — and the strategic risk is that Bridger's competing Guernsey-to-Cushing project ultimately undermines Pony Express's pricing power. The take-or-pay underwriting provides a buffer, but not an exemption.
Investable names tied to this transaction
- 10–11x forward EV/EBITDA on Tallgrass crude lands at the high end of midstream but is justified by take-or-pay underwriting and a pre-sold PXP2 expansion to ~515 kbpd by late 2027.
- DCF-per-share accretion expected in the first full year of ownership, with 2026 guidance of C$5.70–C$6.10 held intact; equity-offering sizing is the next datapoint investors need.
- Net Debt/EBITDA at 5.2x sits at the top of the 4.5x–5.0x target band, so the equity component matters more than the headline price.
- Long-term: integrates Enbridge into every link of the U.S. crude value chain from Delaware Basin wellhead to Ingleside export — a position no other midstream operator can match organically.
- Retains its 25% non-operating Pony Express interest post-deal, so cash-flow economics from the pipeline are unchanged; the counterparty swap from Tallgrass to Enbridge is credit-positive.
- Operational risk: Phillips 66 has been actively divesting midstream non-core (sold 25% REX to Tallgrass for $1.275B in 2024, 25% GCX in Dec 2024); the Pony Express stake is now an even larger share of its Midstream segment economics.
- Short-term: deal close later 2026 is the catalyst for a Midstream segment value re-marking; no cash impact to PSX.
- Long-term: Pony Express remains a contracted, fee-based asset on PSX's books; whether PSX later exits this stake is an open question now that Enbridge is operator.
- Competes directly with Pony Express via its 1,915-mile Bakken Pipeline (up to 750,000 bpd) for Rockies/Bakken crude takeaway to Cushing.
- Ongoing ~$5.0B–$5.5B 2026 growth capex is split toward natural gas — strategic positioning mirrors Tallgrass's, not Enbridge's.
- Short-term: FTC review of the Enbridge/Tallgrass deal is the catalyst to watch — a clean clearance validates further consolidation; conditions could open space for ET.
- Long-term: ET's gas-heavy mix and Sunoco partnership remain the more direct play on the LNG/data-center demand surge that is driving Tallgrass's gas retention.
- Competes with Enbridge at Cushing and along the Gulf Coast; the consolidated Enbridge platform increases competitive pressure on EPD's crude franchise.
- Trailing EV/EBITDA of 11.1x is close to the multiple Enbridge just paid for Tallgrass — a useful comparable if EPD pursues its own crude M&A.
- Short-term: Q3 2026 earnings will show whether EPD is gaining or losing Cushing share to the combined Enbridge/Salt Creek/Pony Express footprint.
- Long-term: EPD's NGL focus and export terminal positions remain differentiators; crude consolidation pressure is the principal risk.
- Limited direct crude overlap — NGL- and gas-focused, with the recent Magellan integration as its consolidation lever.
- Trades at 11.9x TTM EV/EBITDA, in line with the multiple Enbridge just paid, so valuation is no obstacle to its own deal-making.
- Short-term: watch whether ONEOK responds to the Tallgrass carve-out signal with its own midstream bolt-ons; its NGL book is the analog to what Blackstone kept at Tallgrass.
- Long-term: OKE's processing-and-fractionation footprint remains the closest analog to the 'gas + NGL growth' thesis Tallgrass is doubling down on.
- Crystallizes ~$2.55B of cash from the Tallgrass crude sale while retaining the higher-multiple, gas-growth optionality (Rockies Express, Permian-to-REX proposal).
- Confirms Blackstone Infrastructure Partners' thesis that the LNG / AI-power gas demand surge is the durable midstream growth trade of the late 2020s.
- Short-term: cash proceeds redeployable into further infrastructure investments; Tallgrass crude sale is also a return-of-capital event for the fund's LPs.
- Long-term: Blackstone keeps the assets that will most benefit from LNG export expansion and data-center gas demand — the assets Enbridge did not want.
