Hormel Foods — The food producer reported quarterly profit of 36 cents per share, beating consensus forecasts by 1 cent a share. Revenue also beat estimates. Hormel's results were driven by strong sales for brands such as Skippy, Spam, and Muscle Milk, and the company also raised its full-year forecast.
Twitter — Evercore downgraded Twitter to "sell" from "hold," saying it sees more risk than reward because of competitive concerns. Evercore specifically cites Snapchat's move toward monetizing its own popular service.

L Brands — The apparel seller beat estimates by 11 cents a share, with adjusted quarterly profit of 70 cents per share. The Victoria's Secret parent also raised its outlook for the full year. The company's' results were helped by a 3 percent rise in comparable-store sales.
NetApp — NetApp came in 10 cents a share above analysts' estimates, with adjusted quarterly profit of 46 cents per share. The data storage company's revenue was essentially in line with forecasts, as is its current-quarter guidance. NetApp's bottom line was helped by cost cuts that offset a revenue decline.
