After a "mixed quarter," Hewlett Packard Enterprise CEO Meg Whitman said the intensity of splitting her companies may have pushed the company to the edge.

"We probably loaded a bit too much on our senior people," Whitman said to CNBC's "Squawk on the Street" on Friday. "We might have just overloaded people. We had a lot of people in new jobs. I pride myself on execution, and it wasn't perfect this quarter. There's no question that I have pushed this organization to probably the limits."
