Take a look at some of Wednesday's morning movers:
Deere - The equipment maker reported fiscal fourth-quarter profit of $1.75 per share, 13 cents below estimates, but revenue exceeded consensus. Deere is seeing continued strength in demand for large equipment, but did note caution surrounding its U.S. livestock and dairy markets.
Time Warner - The media giant announced a new five-year employment agreement with Chief Executive Officer Jeff Bewkes.
Salesforce.com - Salesforce reported third-quarter profit of $0.33 per share, one cent above estimates, with revenue also coming in ahead of consensus. However, the business software company's fourth quarter earnings guidance of $0.38 to $0.40 per share is largely below Street estimates of $0.40. Analysts have been concerned about whether Salesforce can maintain its rapid growth rate amid increasing competition.
Zale - Zale posted a fiscal first-quarter loss of $0.88 per share, $0.20 wider than consensus estimates. The jewelry retailer has seen its business improve this year on higher prices, better inventory, and new products, but Zale remained in the red for the third consecutive quarter.
Cirrus Logic - Cirrus has authorized $200 million in share repurchases, with the timing depending on a variety of factors. The chipmaker's shares have nearly doubled this year and it reported strong fiscal second-quarter earnings late last month.
Chipotle Mexican Grill - Chipotle has added another $100 million to an existing $100 million share buyback program that had been announced last month. The restaurant chain has already bought back about $40 million in shares under that previous program.
Hewlett-Packard - Several firms have now downgraded the stock, following an $8.8 billion writedown related to its purchase of Autonomy last year. It said there were "serious accounting improprieties" at Autonomy, while ex-CEO Mike Lynch told CNBC Autonomy was simply destroyed by mismanagement at HP.

Wal-Mart Stores - The retailer will see protestors outside its stores Friday, as the National Labor Relations Board will not make a decision before Thanksgiving on Wal-Mart's motion to stop workers from picketing.
Research In Motion - RIM may be losing another major customer for its BlackBerry smartphones. The Wall Street Journal reported the National Transportation Safety Board is considering dropping the BlackBerry in favor of Apple's iPhone, citing reliability issues.
Mylan - Mylan's credit rating has been upgraded by both Moody's and Standard & Poor's, with the drugmaker's rating now out of junk territory. Moody's upgraded Mylan by two notches to Baa3, one level above junk, while S&P lifted its rating by one notch to BBB-, also one notch above junk. This follows Mylan's moves to improve operating performance and free cash flow. Additionally, Mylan's board has approved a $500 million stock repurchase program.
Novartis - Novartis has received U.S. Food and Drug Administration approval for a new season flu vaccine that can be manufactured much more quickly than traditional vaccines.
Scholastic - Scholastic has slashed its 2013 profit guidance because of school district cutbacks, among other reasons. It now expects to earn $1.40 to $1.60 per share for the fiscal year, down from its prior $2.20 to $2.40. Current street estimates are at $1.91 a share.
