Check out the companies making headlines after the bell Tuesday:
Hewlett Packard Enterprise's stock soared on news it would spin off its enterprise services unit, which will merge with Computer Sciences. The deal came as HPE posted better-than expected revenue in the fiscal-second quarter after its November separation from HP Inc.
Computer Sciences shares also bounced on the merger announcement, while shares of rival Xerox dipped briefly.
Shares of financial software company Intuit sank after it reported earnings, even though leadership upped full year guidance. Intuit reported adjusted earnings of $3.43 on revenue of $2.3 billion, topping Wall Street's estimates of $3.19 per share on $2.25 billion in revenue, according to the Associated Press.
The company said it now expects revenue growth of 11 to 12 percent for the full fiscal year.
The maker of QuickBooks and TurboTax got a boost Monday by a favorable view from Goldman Sachs, as an analyst banked that small business growth would raise share prices.
Insurance company Chubb saw shares pop briefly in extended trading after it announced a new suite of liability policies for family offices.
"There are significant liability exposures associated with managing and working for a family office," said Steven Goldman, executive vice president. "Family office executives and professional staff can be sued for a broad array of liability issues ranging from employment discrimination and the mismanagement of funds to professional negligence."
Shares of energy companies wavered in extended trading as oil prices breached $49 for the first time since October 2015. Crude inventories fell by 5.1 million barrels in the week ended May 20 to 536.8 million, compared with expectations for a 2.5 million-barrel decline, the American Petroleum Institute told Reuters.
Natural gas companies Chesapeake and Devon ticked higher after the news while renewable energy producers NRG edged lower. Marathon Oil and ConocoPhillips were also up in light volume.
Telecom contracting company Dycom Industries rose after it reported better-than-predicted quarterly results. Dycom posted adjusted earnings of $1.08 per share on sales of $664.4 million, above the 75 cents per share on $598 million expected by Wall Street, according to the Associated Press.
