此前有消息：博通计划以超过220多亿美元现金价格收购赛门铁克，同时还将支付赛门铁克的现有债务，预计最快会在7月中旬达成收购协议。然而，在早些时候却传出博通后续下调收购金额，导致收购赛门铁克事宜以失败告终。
依照消息指出，博通原本有意以每股28.25美元价格收购赛门铁克，而此报价高出赛门铁克原本以每股28美元计算的最低可接受价格，但后续在针对赛门铁克进行尽职调查 (due diligence)，博通却将出价调整为每股27.25美元，使得赛门铁克对于博通出价收购事宜产生犹豫，最终导致此笔交易以失败告终。
市场看法认为博通目前发展作法更趋近私募股权公司，藉由收购需要资金挹注的公司，并且透过削减成本、重组等方式让收购公司以全新面貌运作，例如在2015年以前身新加坡Avago形式收购博通，后续更以博通作为业务合併后的新公司名称，更在执行长陈福阳 (Hock Tan)带领之下持续对外收购，甚至一度计画收购Qualcomm，最后则是被川普政府以危及国家安全为由下令禁止。
不过，以赛门铁克目前确实需要资金的情况，拒绝博通收购其实也令人费解，但有部分原因可能与对博通收购后续处理事宜持疑有关。

It could not be determined why the price negotiations broke down. Broadcom was last week willing to offer as much as $28.25 per share in cash for Symantec and was hoping to ink a deal on Monday, one of the sources said. CNBC, which first reported the news on Monday, said Symantec was looking for more than $28 per share.
Prior to reaching a deal with Starboard Value LP last year that gave it representation on Symantec’s board, the Mountain View, California-based company explored going private, according to the sources.
Symantec]The sources asked not to be identified because the matter is confidential. Broadcom and Symantec did not respond to requests for comment.
Symantec’s]Symantec is struggling with severe competition from nimbler rivals. Several top executives, including CEO Greg Clark, have left the company this year, and it is also being investigated by U.S. regulators over an accounting irregularity.
Symantec]Broadcom, whose chips power smartphones, computers and networking equipment, is trying to diversify into software after U.S. President Donald Trump’s administration last year scuttled its $117 billion bid to buy mobile chipmaker Qualcomm Inc (QCOM.O).
The Symantec deal would have followed Broadcom’s $18.9 acquisition of U.S. business software company CA Inc last year.
