Pilot Flying J CEO Jimmy Haslam will make a statement to the media at 4 p.m. at Pilot headquarters, according to a spokeswoman.
Cynthia Moxley said the executive will not take questions at the event. It is not clear what he will say.
The move comes as Pilot Flying J faces intense pressure in connection with a criminal investigation by the FBI.
On Monday, federal agents raided Pilot facilities including its headquarters on Lonas Drive.
In an affidavit unsealed on Thursday, the government released documents in which recorded conversations and information from unnamed informants were used to allege that certain Pilot employees have conspired and schemed to engage in rebate fraud for many years.
