Six of Qualcomm Inc.’s directors, including Chief Executive Steve Mollenkopf, failed to win support from a majority of the company’s shares Friday, a significant protest vote that signals investor discontent after the chip-making giant successfully rebuffed a hostile takeover from Broadcom Ltd.

At the company’s annual meeting in San Diego, just 40% to 50% of the total shares outstanding were voted in favor of the six directors, with the other four getting more than 50%, according to a person familiar with the count.

An 11th director, former Chairman Paul Jacobs, wasn’t nominated to stand for re-election after a dispute with other board members over his desire to make a bid for the company.

All the directors will remain on the board since they were running unopposed after the U.S. government blocked Broadcom’s bid, and by extension its six-member slate of nominees. The vote count for the originally scheduled meeting that would have pitted the Broadcom slate against Qualcomm’s nominees showed Broadcom winning at least four seats and with a path to get up to six, people familiar with the matter have said.

The latest numbers are preliminary—a tally will be disclosed next week—and subject to change.
