DT Midstream closes $1.2 billion acquisition of three Midwest natural gas pipelines
DT Midstream completed its acquisition of Guardian Pipeline, Midwestern Gas Transmission and Viking Gas Transmission from ONEOK parties effective 11:59 p.m. Central Time on December 31, 2024, for a $1.2 billion purchase price. The company said the deal expands its pipeline segment revenue contribution, backed by take-or-pay contracts with utility customers, but the filing does not provide financial results for the acquired assets.
Key points
- Purchase price of $1.2 billion, paid in cash per the press release
- Acquired pipelines have total capacity of more than 3.7 Bcf/d and about 1,300 miles across seven states
- Purchase agreement dated November 19, 2024, with ONEOK Partners Intermediate Limited Partnership and Border Midwestern Company
- No pro forma financial statements required, as the deal does not exceed 20% significance under Regulation S-X 3-05
