Check out which companies are making headlines after the bell on the eve of Election Day:
Shares of Mylan dropped more than 2 percent after the bell, following news that the U.S. Senate Judiciary Committee called on the Federal Trade Commission to review the company's business practices with respect to EpiPens for possible anti-competitive behavior. In September, New York state's attorney general launched a probe after a preliminary review revealed Mylan might have inserted anti-competitive terms into its deals to sell EpiPens.
Hertz Global shares were down more than 25 percent after the company reported earnings Monday. The company said it sees 2016 adjusted earnings per share between 51 cents and 88 cents. U.S. rental revenue decreased 2 percent year over year, driven by a 1 percent increase in volume, and a 3 percent decline in rate per day, compared to the same period last year. John Tague, president and chief executive officer, said the company was making progress in foundational aspects of its long-term business improvement plan.
"While we remain on pace to deliver $350 million of cost reduction in 2016, we fell short from a timing perspective on our internal stretch target for cost reduction," he said. "Considering this and the potential for an additional depreciation rate adjustment in the fourth quarter, we are updating our 2016 outlook and taking incremental actions to reduce costs and drive revenue."
Rupert Murdoch's News Corp gained 5 percent briefly in extended trading Monday. The company reported fiscal first-quarter results that were roughly in-line with analyst estimates. It posted an adjusted loss of one cent per share on $1.97 billion in revenue. Analysts projected the global media company to report breakeven on $1.96 billion in revenue, according to a Thomson Reuters consensus estimate.
Marriott International's stock was down more than 2 percent in after-hours trading after the company reported earnings. The company posted adjusted earnings of 91 cents per share, beating estimates of 88 cents a share. It missed on its top line, however, reporting revenues of $3.77 billion, compared to estimates of $4.07 billion. Reported revenues excluded its recent Starwood acquisition.
