Hain Celestial has insisted a review into the company's share practices will not affect its annual results for the last 12 months.

The US-based natural and organic group launched an internal investigation into its stock option dealings after US share watchdog The Securities and Exchange Commission launched its own probe.

Hain Celestial, the company behind brands including Rice Dream and Linda McCartney, said its review is ongoing and would lead to delay in the filing of its annual report.

Hain Celestial said it recognised that the delay would lead to the NASDAQ exchange issuing it with a delisting notice.

The company added: "The company expects the notice to be rescinded upon filing its Form 10-K and, in the interim, does not expect the notice to affect the liquidity of the trading in the Company's stock."

Last month, Hain Celestial posted bumper annual results with profits up almost 30%.
