Shares of BP jumped Wednesday, lifted by a report that Shell was in talks to acquire it in what would mark a huge deal for the pair of U.K. oil giants, before giving back their gains.
BP’s (BP) U.S.-traded stock was recently up a bit less than 2%, well off intraday highs, while Shell’s (SHEL) was off less than 1%. The Wall Street Journal, citing people familiar with the matter, wrote that the companies were in “early stage talks” to merge, which powered more dramatic moves early in the session.
A Shell spokesperson called the report “speculation” in emailed comments, saying that “no talks are taking place.” Bloomberg in early May wrote that Shell was studying a possible deal.
BP did not respond to Investopedia’s request for comment in time for publication.
A deal would combine two massive oil companies. Shell’s market capitalization is around $208 billion, according to Visible Alpha, while BP’s was around $79 billion.
“As we have said many times before, we are sharply focused on capturing the value in Shell through continuing to focus on performance, discipline and simplification,” the Shell spokesperson wrote earlier Wednesday.
