Check out the companies making headlines after the bell Monday:
Disney's shares edged lower after an executive who was eyed as a potential CEO contender announced his departure. Thomas Staggs said he would leave his post as chief operating officer May 6, though he would remain in the company as special advisor to the CEO.
Staggs was widely thought to be the successor to now-CEO Bob Iger, The New York Times reported. Iger will step down in about two years, Disney said in a statement, as the board expands its succession planning.
Tesla Motors shares dipped in extended trading Monday after the electric-car company reported fewer first-quarter deliveries than expected. The luxury car brand delivered 14,820 vehicles in the first quarter, below the 16,000 expected by Wall Street.
The news came after the stock closed nearly 4 percent higher in regular trade amid blockbuster sign-ups for the newly unveiled Tesla Model 3.
Shares of drugmaker Allergan tumbled after reports that new Treasury rules would affect Allergan's merger with Pfizer.

Mobile carrier Sprint saw shares pop after reports that Sprint customers would gain access to an Amazon Prime add-on for $10.99 a month. The Sprint deal offers customers the chance to pay a slight premium for month-to-month access, International Business Times reported.
