Teen apparel retailers are struggling to keep their customers as fast-fashion companies such as Inditex's Zara and H&M eat into their market share.

Aeropostale said it was facing disruption in the supply of some merchandise due to a vendor dispute with an affiliate of Sycamore Partners.

If the issue is unresolved, it could lead to a liquidity constraint, the company said.

"Regrettably, our short-term visibility is limited by our current vendor dispute," Chief Executive Julian Geiger said in a statement.

The company has retained Stifel and other advisers to assist in a review of alternatives.
