Crocs stock fell 3% in premarket trading on Thursday, as investors worried about how the business will pay its $2.5 billion acquisition of privately held Heydude.

The company will take a $2 billion loan and a $50 million credit under an existing revolving facility with its bankers to pay the $2.05 billion cash portion of the purchase.Crocs logo and symbol, meaning, history, PNG

It would also issue $450 million worth of its own stock to Heydude founder and CEO Alessandro Rosano, raising concerns about a decline in earnings per share. Given Crocs' market worth of $8.23 billion as of Wednesday's close, the dilution is anticipated to be greater than 5% of the stock.

The casual footwear company will operate as a separate subsidiary of Crocs after the sale is completed, which is expected to happen in March.

Crocs stock has more than doubled in the last year, indicating the company's recovery from near-bankruptcy a few years ago. By 2026, the corporation hopes to generate $5 billion in revenue. Analysts estimate that current-year revenues will be $2.27 billion, according to a major newswire.
