Check out the companies making headlines after the bell Monday:
Solar company SunEdison shares rose as much as 6 percent after hours on news that it would form a $1 billion warehouse investment vehicle, WSIP Warehouse, along with funds managed by Goldman Sachs, according to Reuters.
Apparel maker Urban Outfitters beat second-quarter earnings estimates by 3 cents with earnings of 52 cents a share, but revenue was light as comparable-store sales rose less than expected. Urban also said its gross margins shrunk slightly less than analysts' forecasts. The stock rose about 5 percent after the announcement.
Sprint shares rose about 1 percent after hours, extending a 10-percent gain netted during regular trading after the mobile company announced that it would abandon two-year contracts, joining T-Mobile and Verizon who have made similar moves.
Lazard, a financial advisory firm, fell about 1 percent in extended trading. Earlier, the company's indirect subsidiary, Lazard Global Total Return and Income Fund, declared a monthly distribution of about 93 cents per share.
