eBay Inc., a global commerce platform and payments leader (NASDAQ:EBAY), today reported that revenue for the fourth quarter ended December 31, 2012 increased 18% to $4.0 billion, compared to the same period of 2011. The company reported fourth quarter net income on a GAAP basis of $751 million, or $0.57 per diluted share, and net income on a non-GAAP basis of $927 million, or $0.70 per diluted share. The increase in non-GAAP earnings per diluted share was driven by double digit user growth across the portfolio, strong gains in mobile adoption, and accelerating growth in the company's Marketplaces business, reflecting a 19% increase in U.S. gross merchandise volume (GMV), excluding vehicles. For the full year, revenue increased 21% to $14.1 billion, compared to 2011. The company reported net income on a GAAP basis of $2.6 billion, or $1.99 per diluted share, and net income on a non-GAAP basis of $3.1 billion, or $2.36 per diluted share. eBay Inc. enabled more than $175 billion of commerce volume (ECV) in 2012, representing growth of 18%. ECV is the total commerce and payment volume across all three business units consisting of Marketplaces GMV, PayPal merchant services net total payment volume and GSI global ecommerce (GeC) merchandise sales. "We had a great finish to an excellent year, with fourth quarter results exceeding our expectations," said John Donahoe, eBay Inc. President and CEO. "eBay Marketplaces in particular had a terrific fourth quarter, with growth in the U.S. accelerating three points, outpacing ecommerce." "Mobile continues to rewrite the commerce playbook, and we continue to be a mobile commerce and payments leader," Donahoe said. "eBay mobile finished the year with $13 billion in volume - more than double the prior year - and PayPal mobile handled almost $14 billion in payment volume, more than triple the prior year. In 2013, we expect each to exceed $20 billion."
