Check out the companies making headlines after the bell Tuesday:

Chipotle Mexican Grill shares slid after hours after the restaurant chain reported its same-store sales fell more than 20 percent the second week of March.

Chipotle saw comparable store sales drop 27.3 percent in the second week of March, it said in a statement Tuesday, after a Boston-area restaurant was closed when employees fell ill. The fast-casual chain trimmed earnings expectations for the first quarter, saying Tuesday it expects a loss of $1 per share or more.

Shares of enterprise technology firm Oracle popped in extended trading after it posted earnings that beat analysts' expectations Tuesday, though revenues fell short.

The company, which has turned to focus on more cloud-based offerings, reported earnings of 64 cents per share on $9.01 billion in revenue, versus the 62 cents per share on $9.12 billion in revenue expected by Thomson Reuters consensus estimates.

Fellow tech company Pure Storage also saw shares rise. The flash-data storage provider debuted new products that caught the eye of analysts and were at the center of a New York Times article Monday featuring innovative approaches to data storage.

Shares of biopharmaceutical company Baxalta dipped briefly after the bell when it announced a $2.34 billion stock offering. The shares, held by former parent company Baxter International, will be exchanged toward debt with lenders like JPMorgan, Bank of America Merrill Lynch, and Credit Suisse, according to a company statement. After the debt-for-equity exchange, Baxter will hold just over 5 percent of Baxalta, the statement said.

Footwear company Caleres's stock sank despite it reporting earnings that exceeded Wall Street's expectations. The company behind Famous Footwear, Sam Edelman and Naturalizer posted net income of 26 cents a share, the AP reported, higher than the 22 cents per share predicted.
