For the second quarter, eBay expects to post adjusted earnings between 61 and 63 cents a share, compared with an estimate of 66 cents a share from analysts surveyed by Thomson Reuters.
Late last month, eBay set aggressive three-year growth targets, based on international expansion plans and more focus on mobile commerce.
The company is investing heavily in these initiatives and such spending may be behind the weaker second-quarter profit forecast, said R.J. Hottovy, an equity analyst at Morningstar.
"These investments are building for the future so that should be taken positively, even if they come at the expense of short-term profits," Hottovy added, while noting that eBay's full-year 2013 forecasts remained unchanged.
