EBay Inc. on Thursday said business has grown faster than it recently expected, improving the company's forecast for its second-quarter results.

The San Jose, Calif.-based e-commerce company said it now expects revenue of between $2.75 billion and $2.8 billion in the second quarter, compared with previously issued guidance of $2.38 billion to $2.48 billion. It expects adjusted earnings per share of between $1.02 a share and $1.06 a share, up from a prior forecast of 73 cents to 80 cents a share.

Analysts were anticipating revenue of $2.46 billion and adjusted earnings per share of 78 cents, according to FactSet.

April and May saw the addition of six million new and reactivated buyers for eBay, the company said. Volume growth will show a 23% to 26% year-over-year improvement in the second quarter, the company forecast, as all major verticals have shown significant acceleration.

Segments with sales growth include home goods, electronics, fashion, car parts and collectibles, eBay said.

EBay did not provide a specific update of its full-year guidance but said that performance over the 12-month period will likely exceed the levels it said in April it anticipated.
