The personal computer maker HP will cut 7,000 to 9,000 jobs from its global work force, the company said on Thursday, estimating that its reorganization plan will save it $1 billion annually by the end of 2022.

HP had about 55,000 employees worldwide at the end of last October, according to a filing with the Securities and Exchange Commission. The company expects to incur about $1 billion in costs in the overhaul.

“We are taking bold and decisive actions as we embark on our next chapter,” said Enrique Lores, the company’s incoming chief executive. “We see significant opportunities to create shareholder value, and we will accomplish this by advancing our leadership, disrupting industries and aggressively transforming the way we work.”

Mr. Lores will take over on Nov. 1 from Dion Weisler, the chief executive since 2015.

HP also said it expected to generate free cash flow of at least $3 billion during its fiscal year in 2020 and planned to increase its quarterly dividend by 10 percent.
