Why Howard Energy Partners is buying Iron Horse Midstream (from Sixth Street)
HEP said the assets, backed by multi-decade customer contracts covering about 167,000 dedicated acres, strengthen its Anadarko Basin position. Combined, its Oklahoma footprint will include nearly 2,000 miles of pipeline, about 2 Bcf/d of pipeline capacity, 580 MMcf/d of processing capacity and 540,000 horsepower of compression.
“We see tremendous long-term opportunity in the Anadarko Basin.”
Deal terms and financing
The acquisition covers about 400 miles of high- and low-pressure gas pipelines in Canadian, Caddo and Grady counties, multiple compressor stations and the 120-acre Iron Horse processing complex with 425 MMcf/d of capacity.
Regulatory approvals and timing
Closing is expected by year-end 2026, subject to customary conditions and regulatory approvals.
Market context
HEP said the deal brings its Midcontinent acquisitions over the past two years to about US$2.5bn, following its purchase of Superior Midstream and the remaining interest in the Midship Pipeline earlier in 2026. Sixth Street made a significant equity commitment to Iron Horse in 2025.
