(Bloomberg) -- Renesas Electronics Corp. of Japan said it’s in talks to acquire Dialog Semiconductor Plc, the U.K. chip designer whose clients include Apple Inc.Renesas is making an all-cash offer of 67.50 euros per share, according to a statement on Monday. It said no final decision has been made and there’s no guarantee it will proceed with the acquisition. The Japanese company would pay about 4.9 billion euros ($5.9 billion) to take over its target, Bloomberg News reported on Sunday.The offer price is a 20% premium to Dialog’s Friday close of 56.12 euros. Shares of the Frankfurt-listed company have risen around 25% since the start of the year, boosted by strong demand for Apple’s 5G handsets as well as takeover speculation.Renesas shares dropped as much as 6.9% in Tokyo.Dialog had been in advanced discussions with suitors including Renesas and working with advisers, people familiar with the matter said on Sunday. The company was previously holding discussions with STMicroelectronics NV before the Franco-Italian company was outbid, the people said at the time.The volume of deals involving semiconductor companies more than doubled last year to $144 billion, according to data compiled by Bloomberg. Nvidia Corp. agreed in September to buy SoftBank Group Corp.’s chip division Arm Ltd. for $40 billion, taking control of some of the most widely used chip technology in the industry’s largest-ever deal.Any deal could draw scrutiny from U.K. regulators as countries grow more protective of strategic industries such as semiconductors. Nvidia’s deal for Arm is set to be investigated by the country’s competition watchdog. The Competition and Markets Authority has said it will apply greater scrutiny to strategic tech deals, regardless of size.The U.K. government is also planning to introduce new rules that would allow officials to look at past takeovers and mergers where concerns have been raised.Renesas, which had a market value of $20.5 billion as of Friday’s close, is one of the largest suppliers of semiconductors used in cars. It also has European offices in the U.K. and Germany. In 2019, Renesas completed its acquisition of U.S. firm Integrated Device Technology Inc., a deal valued at more than $6 billion that helped it expand beyond the automotive sector.Dialog and Renesas have been working together for over a decade. The U.K. company, which specializes in designing power management chips, said in August that it would collaborate with Renesas on car computing platforms.Both companies have found themselves part of tensions concerning the semiconductor supply chain. Apple was grappling with a shortage of vital chips that manage power consumption in iPhones and other devices, people with knowledge of the matter said in November. Within the auto industry, a semiconductor shortage is forcing car makers to halt production lines and is straining their relationship with chip suppliers.Like Dialog, Renesas is also a supplier to Apple. The U.S. tech giant was reported to be in talks to buy Renesas SP Drivers, 55% owned by Renesas, in 2014. The unit, which managed LCD displays, was later sold to Synaptics Inc. for $475 million.For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
