The electronic payments firm PayPal, a subsidiary of eBay, said it would acquire the digital money transfer provider Xoom for about $890 million enterprise value. Xoom shares were up about 12 percent before being halted. Ebay and Paypal are slated to spin off from each other later this month.

Delta shares were little-changed after the airline said it received a civil investigative demand from the U.S. Justice Department, although it did not specifically mention the term "collusion." Airline stocks were broadly lower earlier after DOJ said it was investigating whether airlines are colluding to keep fares high.

S&P affirmed its negative outlook on medical products company Baxter International, citing risks that its debt leverage may decline to below a key level. Shares fell about 1 percent before recovering.

Discount retailer Family Dollar said adjusted third-quarter earnings declined to 74 cents a share, down from 85 cents a share a year ago, while net sales rose 2.6 percent. Shares were flat in extended-hours trading.

Energizer Holdings's shares dipped about 3 percent after hours. Earlier, the company known for its battery business, said it completed a spinoff from its former parent company, which now operates under the name Edgewell Personal Care.
