Qualcomm Inc. QCOM, +0.35% shares shot up 3.3% in after-hours trading Thursday following a CNBC report that former chairman and chief executive Paul Jacobs is leading a fund-raising effort to buy the chipmaker and take it private. Jacobs, whose father co-founded the company, was ousted from the board in March after expressing his plan to go private. CNBC said Jacobs is talking to strategic investors and sovereign wealth funds to put together a bid within the next couple of months. Under Jacobs' plan, the company would remain based in the U.S. and he would take over as CEO, a role he had from 2005 to 2014, CNBC said. Last month, Broadcom Ltd.'s bid to buy Qualcomm fell apart after it was blocked by President Donald Trump. Qualcomm shares ended the regular trading session up slightly, at $55.20.
