Market Movers Today: CSRA Inc (CSRA), Ulta Beauty Inc (ULTA), Stamps.com (STMP), and More

CSRA Inc (NYSE:CSRA) (Bloomberg)
General Dynamics Corp., the maker of Abrams tanks and nuclear submarines, is making a record bet on reinvigorating its information-technology business. The U.S. defense contractor agreed to buy CSRA Inc. for about $6.8 billion to expand its computer-services offerings for government agencies and military customers. CSRA holders will receive $40.75 a share in cash, General Dynamics said in a statement Monday, a 32 percent premium over the closing price at the end of last week. “What we’re doing with this transaction is taking our good GDIT business and making it better, stronger, a more viable competitor,” General Dynamics Chief Executive Officer Phebe Novakovic said on a conference call with analysts and investors. “It’s low risk. It’s got terrific return on invested capital and great cash flow.” General Dynamics fell less than 1 percent to $210.70 at 10:51 a.m. in New York. CSRA surged 31 percent to $40.47.

Ulta Beauty Inc (NASDAQ:ULTA) (MarketWatch)
Ulta Beauty Inc. ULTA, -4.42% shares are down 4.3% in Monday trading after a lawsuit filed in Chicago federal court alleges the chain sold used cosmetics. A Chicago Tribune report says a California woman is seeking class-action status for the suit, which accuses Ulta of repackaging returned cosmetics and selling them alongside never-opened merchandise. Former employees have tweeted alleging the practice. “The suit is not based on evidence of a health outbreak or product efficacy, which may ultimately make it easier to defend,” wrote Jefferies analysts in a note. “But in the court of public opinion, any sort of social driven campaign that challenges consumer perception of safety is a risk.”

Sapiens International Corporation N.V. (NASDAQ:SPNS) (Benzinga)
Sapiens International Corporation N.V. dropped 14.4 percent to $10.10. Sapiens Intl narrowed its FY2017 sales guidance and issued a weak FY18 sales forecast.

Stamps.com Inc. (NASDAQ:STMP) (The Motley Fool)
What happened: Shares of postage payment facilitator Stamps.com (NASDAQ:STMP) dropped as much as 11% in early trading Monday, before reviving to book “only” a 7.1% loss as of 12:15 p.m. EST. Stamps.com hasn’t reported anything noteworthy today, nor are its earnings out just yet. So what: Instead, I think you can blame Amazon.com (NASDAQ:AMZN) for this one. Three months ago, Stamps.com reported a big earnings beat, but said Amazon was bringing some of its “Fulfillment by Amazon” postage billing in-house and that might affect Stamps.com’s business going forward.
