Check out which companies are making headlines before the bell:
Hilton Worldwide–The hotel operator reported first quarter profit of 13 cents per share, excluding certain items, four cents above estimates. Revenue beat consensus as well, and Hilton also raised its full year forecast as revenue per available room and management and franchise fees all rose strongly.
Bloomin' Brands–The operator of Outback Steakhouse and Bonefish Grill earned 46 cents per share for the first quarter, one cent short of estimates, with revenues shy of forecasts. The company cited bad weather and shifts in holiday timing as negative factors for the quarter.
Vivus– Drug maker Actavis has filed an application to market a generic version of the Vivus diet drug Qsymia. Vivus said it will move to enforce its intellectual property rights.
CBS–The broadcast giant reported first quarter profit of 78 cents per share, four cents above estimates. However, revenue fell short of projections amid a 12 percent drop in advertising sales.
Apple –The tech big is in talks to acquire headphone maker Beats for $3.2 billion, according to multiple reports. Apple's interest in Beats also has headphone maker Skullcandy on watch.
Omnicon, Publicis–The advertising agencies have called off their $35 billion merger, citing multiple complex issues that couldn't easily be resolved.
ArcelorMittal–The steel maker lowered its forecast for global steel demand, saying it should increase by 3 to 3.5 percent this year compared to a prior forecast of 3.5 to 4 percent. That outlook from the world's largest steelmaker could pressure other steel stocks like U.S. Steel.
Boston Scientific–Boston Scientific has been subpoenaed by the Department of Health and Human Services for information about two of its implanted defibrillators.
RadioShack–The electronics retailer is scaling back its plan to close as many as 1,100 stores, after being unable to reach an agreement with its lenders. Its current credit agreements do not allow closing more than 200 stores during 2014.
News Corp.–The media giant earned 11 cents per share, excluding certain items, for its third quarter, beating Street estimates by eight cents. The company's newspaper business suffered declining revenue, but improved results in book publishing and elsewhere helped News Corp.'s bottom line. Separately, the company named interim Dow Jones CEO William Lewis to the full-time CEO position.
Tesla–Tesla is facing a sales barrier in yet another state, with Missouri considering a bill to restrict selling automobiles directly to consumers and bypassing dealers.
Gap–Gap reported a nine percent increase in same-store sales for April, topping estimates, and the parent of the Gap, Banana Republic, and Old Navy chains also projected current quarter profit above current Street consensus.
Symantec–Symantec beat estimates by five cents with fiscal fourth quarter profit of 47 cents per share, excluding certain items. The maker of security software is also predicting full-year profit above analyst forecasts, aided by cost-cutting measures.
GrubHub–GrubHub earned six cents per share for the first quarter, beating estimates by three cents, with revenue and the online food-delivery service's current quarter forecast also above estimates.
Jazz Pharmaceuticals–The company fell 18 cents short of estimates with first quarter profit of $1.61 per share, excluding certain items, with revenue and the drug company's full-year outlook also falling short.
Monster Beverage–Monster's reported first quarter profit of 55 cents per share, six cents above estimates, but the energy drink maker's revenue was shy of analyst forecasts. Its bottom line was helped by both a lower tax rate and smaller operating expenses.
