With a 50,000-mile pipeline network, the company transports natural gas, NGLs, refined products and crude oil, supporting both domestic and international energy demand.

In November, ONEOK reached an agreement to acquire the remaining common units of EnLink Midstream in a tax-free transaction valued at $4.3bn.

The acquisition, set to close in the first quarter of 2025, will involve ONEOK issuing approximately 37 million shares.

Under the terms of the deal, each outstanding EnLink unit will be converted into 0.1412 shares of ONEOK common stock.

ONEOK has also agreed to sell three interstate natural gas pipelines – the Guardian pipeline, Midwestern gas transmission and Viking Gas Transmission – to DT Midstream for $1.2bn.

This move is part of ONEOK’s strategy to optimise its asset portfolio. The combined 1,300-mile pipeline network has a total capacity of more than 3.7 billion cubic feet per day.
