Aeropostale Inc. (ARO) on Monday unveiled a management shake-up as the struggling teen-apparel retailer also projected a narrower loss for the second quarter.

Dick's Sporting Goods said its fiscal second-quarter profit slid 17% as higher revenue was offset by increased expenses and a restructuring charge tied to its golf business. Shares edged up 5.1% to $45.72 premarket.

Elizabeth Arden said its fiscal-fourth quarter loss widened sharply as a larger-than-expected drop in celebrity-fragrances sales pushed down revenue.

(MDT) said Tuesday that it is "fully committed" to completing its deal to buy Covidien PLC, which has come under scrutiny over a controversial tax tactic that has drawn criticism from U.S. government officials. The medical-devices maker also posted fiscal first-quarter results that exceeded analysts' expectations. Shares rose 1% to $64.07 premarket.

Skilled Healthcare has agreed to merge with Genesis HealthCare in an all-stock deal that expands Genesis' geographic reach and creates the second-largest contract therapy provider. Shares surged 28% to $7.85 premarket.

TJX Cos. (TJX) said its fiscal second-quarter earnings rose 7.9% and beat expectations as the retailer benefited from higher sales and increased customer traffic.
