Oil giant BP has been thrust into the spotlight as a prime takeover candidate — but energy analysts question whether any of the likeliest suitors will rise to the occasion.

Britain’s beleaguered energy giant, which holds its annual general meeting on Thursday, has recently sought to resolve something of an identity crisis by launching a fundamental reset.

Seeking to rebuild investor confidence, BP in February pledged to slash renewable spending and boost annual expenditure on its core business of oil and gas. CEO Murray Auchincloss has said that the pivot is starting to attract “significant interest” in the firm’s non-core assets.

BP’s green strategy U-turn follows a protracted period of underperformance relative to its industry peers, with its depressed share price reigniting speculation of a prospective tie-up with domestic rival Shell. U.S. oil giants Exxon Mobil and Chevron have also been touted as possible suitors for the £54.75 billion ($71.61 billion) oil major.

Shell declined to comment on the speculation. Spokespersons for BP, Exxon and Chevron did not respond to a request for comment when contacted by CNBC.

“Certainly, BP is a potential takeover target — no doubt about that,” Maurizio Carulli, energy and materials analyst at Quilter Cheviot, told CNBC by video call.

“I would conceptualize the question of ‘will Shell bid for BP’ in the more general consolidation that it is happening in the resources sector, both oil but also mining — particularly in the past year a lot of companies thought that to buy was better than to build,” he added.

In the energy sector, for example, Exxon Mobil completed its $60 billion purchase of Pioneer Natural Resources in May last year, while Chevron still seeks to acquire Hess for $53 billion. The latter agreement remains shrouded in legal uncertainty, however, with an arbitration hearing scheduled for next month.

In the mining space, market speculation kicked into overdrive at the start of the year following reports of a potential tie-up between industry giants Rio Tinto and Glencore. Both companies declined to comment at the time.

Quilter Cheviot’s Carulli named Chevron as a potential suitor for BP, particularly if the U.S. energy giant’s pursuit of Hess falls through.

Speculation about a potential merger between Shell and BP, meanwhile, is far from new. Carulli said that while the rumors have some merit, a prospective deal would likely trigger antitrust concerns.

Perhaps more importantly, Carulli added that a move to acquire BP would conflict with Shell’s steadfast commitment to capital discipline under CEO Wael Sawan.

Michele Della Vigna, head of EMEA natural resources research at Goldman Sachs, described BP’s recent strategic reset as “very wise” and “thoughtful,” but acknowledged that it may not have gone far enough for an activist investor.

U.S. hedge fund Elliott Management has reportedly built a near 5% stake to become one of BP’s largest shareholders. Activist investor Follow This, meanwhile, recently pushed for investors to vote against Helge Lund’s reappointment as chair at BP’s upcoming shareholder meeting in protest over the firm’s recent strategy U-turn. BP has since said that Lund will step down, likely in 2026, kickstarting a succession process.

“I think there are three major optionalities in BP’s portfolio that any activist investor would love to see monetized. The first one is not all in BP’s hands, it’s the monetization of the Rosneft stake,” Della Vigna told CNBC over a video call.

BP announced it was abandoning its 19.75% shareholding in Russian state-owned oil company Rosneft shortly after Moscow’s full-scale invasion of Ukraine in late February 2022. It had marked a costly and abrupt end to more than three decades of activity in the country.

A second optionality for BP, Della Vigna said, is the firm’s marketing and convenience business.

“I mean, within BP, a company that trades on three times EBITDA, there’s a division that can trade at 10 times EBITDA, right? Amazing. You can make the same point for a lot of the other Big Oils,” Della Vigna said.

EBITDA is a standard metric that refers to a firm’s earnings before interest, tax, depreciation and amortization.

“The third option is BP is a U.S.- centered energy company — and it’s clear, right? BP is the most U.S.- exposed of all the majors, more than Exxon and Chevron,” Della Vigna said, noting that 40% of BP’s cash flow comes from the U.S.

“So, being listed in the U.K., when the U.K. gets you the biggest discount of any other region in Big Oil, doesn’t feel right. I think some form of relocation or transatlantic merger may be worth considering,” he added.
