Cisco will cut thousands of jobs in a second round of layoffs this year as the U.S. networking equipment maker shifts focus to higher-growth areas, including cybersecurity and AI, people familiar with the matter said.

The number of people affected could be similar to or slightly higher than the 4,000 employees Cisco laid off in February, and will likely be announced as early as Wednesday with the company’s fourth-quarter results, said the sources, who were not authorized to speak publicly.
