NATCHEZ — The company that once promised Adams County 320 jobs will be delisted from a national stock exchange next week.

In a Monday filing with the Securities and Exchange Commission, KiOR said the Nasdaq stock market had notified the company it would be delisted Sept. 23 because its stock had fallen below $1 per share and because it could not demonstrate minimum market values required by the exchange.

“(KiOR) does not believe that it will be able to regain compliance with the Nasdaq listing rules … prior to the end of the applicable grace periods,” the filing states.

KiOR’s stock was once valued at more than $20 a share following its initial 2011 offering, but was trading Thursday at approximately $0.21 a share.

The Pasadena, Texas-based company built a full-scale cellulostic fuel plant in Columbus and announced plans for a second one in Natchez in 2012, but technical and logistical delays in Columbus delayed the Natchez project and a proposed second Columbus facility.

The delays and technical issues forced the company to idle its Columbus operations earlier this year, and multiple rounds of layoffs followed.

In August, the company warned it was close to running out of operating cash and might have to pursue bankruptcy. The same month, KiOR defaulted on the land contract it had with Adams County for its proposed location, the former Belwood Country Club.

County officials have since said the property is considered back on the market for other industrial prospects.

KiOR spent a reported $10 million in preparation for the Natchez project.
