US shale independent Continental Resources has received a $4.8 billion all-cash offer from its billionaire founder Harold Hamm and the Hamm Family Trust to acquire the outstanding 17.431% equity they do not already own.

The move, which puts a $25.4 billion valuation on the company, would take the US shale producer private. If agreement is reached, this would be the most significant deal in the US shale sector this year.

Hamm, a native Oklahoman, began his career in oil and gas over five decades ago, starting out with a single oil service truck and a dream.
