Home Depot's same-store sales in the U.S. gained 6.2%, likely helped by continued demand for building materials from contractors and appliances on the part of consumers.

3. -- Shares of Kraft Heinz (KHC) - Get Kraft Heinz Company (KHC) Report were down 3.8% in premarket trading on Tuesday after it agreed to withdraw its bid for Unilever (UL) - Get Unilever PLC Sponsored ADR Report  over the weekend.

"Kraft Heinz's interest was made public at an extremely early stage. Our intention was to proceed on a friendly basis, but it was made clear Unilever did not wish to pursue a transaction," Kraft Heinz spokesman Michael Mullen told TheStreet via email.

The maker of Kraft mac and cheese and Heinz ketchup on Friday said it approached consumer products giant Unilever with a $143 billion offer but the offer was quickly rejected by Unilever, which said Kraft Heinz's offer "fundamentally undervalued" the company.

Shares of Unilever fell 6.6% in London on Monday, the day after Kraft Heinz withdrew its bid. American depositary receipts of Unilever were down 8.5% in premarket trading in the U.S. on Tuesday.

4. --  HSBC (HSBC) - Get HSBC Holdings PLC Sponsored ADR Report  shares fell sharply in London after Europe's biggest bank posted much lower-than-expected full-year earnings and increased its buyback program after taking a multi-billion dollar write-down on its European private banking assets. 

Pretax full-year profit was $7.1 billion, down 62% from 2015 and well shy of the $14.4 billion forecast by analysts. Profit on an adjusted basis was $19.3 billion while revenue for the full year was $50.2 billion. HSBC said its bottom line was hit by a $3.2 billion goodwill write-down on its private banking division in Europe, which was linked to the purchase of Safra Republic Holdings in 1999.

The stock was down 6.6% in trading Tuesday in London. 

"We have considered it appropriate to write off the remaining goodwill in the European private banking business," said CEO Stuart Gulliver. "The restructuring of Global Private Banking is now largely complete, and although Global Private Banking is now much smaller than it was three years ago, it is deliberately positioned for sustainable growth with a focus on serving the personal wealth management needs of the leadership and owners of the Group's corporate clients."

HSBC added $1 billion to its share buyback program, taking the total amount of the program to more than $3.5 billion.

5. -- An acquisition of Popeyes Louisiana Kitchen (PLKI) could happen later this week, according to a report.

Restaurant Brands International (QSR) - Get Restaurant Brands International Inc Report , the parent of Burger King and Tim Hortons, could announce a deal to buy Popeyes, the chain known for its deep-fried chicken, fries and buttermilk biscuits, Reuters reported.

The deal could value Popeyes at more than $1.7 billion, Reuters reported, citing people familiar with the deal.
