Hansen Natural Corp. said Monday that it received a letter from Nasdaq saying the company is in danger of having its stock delisted because it had yet to file its quarterly report for the quarter ending Sept. 30.

The Corona-based tea, juice and soda maker said earlier this month it would delay filing its financial results because of an internal investigation into stock options accounting.

The company said it would file results as soon as it has completed its investigation and added it plans to request a hearing with the exchange’s listing qualifications panel to review the decision. The company will remain on the Nasdaq pending a decision by the panel.

Shares of Hansen were down 22 cents to $27.17 in early trading Monday.
