Private equity giant KKR & Co. has made a takeover bid for UGI Corporation, the Pennsylvania-based natural gas and electricity distributor, at $42.50 a share — a deal that would value the company at roughly $9 billion, according to a Wall Street Journal report that sent UGI's stock soaring Tuesday before trading was halted.

UGI shares jumped as much as 12.3% before the volatility halt kicked in, with trading frozen around $37.20, according to a Reuters wire report carried by Investing.com. The stock had been trading around $35 before the news broke, meaning KKR's reported offer represents roughly a 20% premium over UGI's recent price. KKR's own shares slipped about 1.5% on the news, a fairly typical reaction for an acquirer taking on new deal risk.

A reported bid, not yet a done deal

Neither KKR nor UGI has issued an official confirmation of the offer or terms. The reporting so far traces back to the Wall Street Journal, with wire services and financial outlets such as Seeking Alpha and TradingView syndicating the same figures: a $42.50-per-share offer and a roughly $9 billion valuation. Because the bid has not been confirmed by either company, the terms — and whether the deal ultimately gets done at all — could still change.

REPORTED OFFER: $42.50 A SHARE, ROUGHLY $9 BILLION VALUATION

UGI, headquartered in King of Prussia, Pennsylvania, distributes natural gas and electricity across the Mid-Atlantic and also owns AmeriGas, one of the largest propane distributors in the country. The company has drawn periodic takeover interest in recent years as utilities have become attractive targets for private equity firms seeking steady, regulated cash flows — an appeal that has only grown as investors look for stability amid volatile equity markets.

KKR, one of the world's largest private equity firms with a long history of infrastructure and energy investments, has not disclosed financing details or a timeline for a formal offer. Analysts covering the utility sector said a deal of this size would likely require regulatory approval in multiple states given UGI's sprawling service footprint, a process that typically takes months even once a definitive agreement is signed.

Trading in UGI shares is expected to resume once exchanges lift the volatility halt, and investors will be watching for any official statement from either company confirming — or denying — the reported terms.
