The company called out increasing competition for loans to borrowers with sub-660 FICO scores for slowing receivables growth, specifically mentioning credit card companies, which have targeted lower-FICO borrowers. While OneMain isn't a credit card issuer, its customers can use cards as a substitute for its core small-dollar unsecured and secured loans.

Now what

The company was previously known as Springleaf. It adopted its new name after closing on the acquisition of OneMain -- then its biggest competitor -- in 2015. Integrating these two companies is proving to be a challenge.

In prepared remarks, one executive noted that "the amount of change we asked of our branch team members simply kept them from bringing a historical level of focus on new business and collections," referring to the company's employees engaged in origination and collection.

That would suggest that weakness in guidance may be short-lived, but the market isn't buying it today, as evidenced by the sharp drop in the company's stock.
