The Namibian quoted Namdia board chairperson Bryan Eiseb as saying that actioned an internal investigation around various irregularities at the company end of last year.
He said the board would implement recommendations, which include the charging of Hamutenya for "a string of violations".
"We have so far appointed the chairperson and the initiator of the disciplinary hearing, but we have not decided on the date yet at this moment," said Eiseb.
The daily alleged, citing unnamed sources, that an amount of N$300 000 in state funds is involved.
Minister of public enterprises Leon Jooste said Hamutenya's disciplinary hearing was being handled by the board.
"This is entirely under the authority of the board and there is no need for the shareholder to get involved," he said.
"This is an internal issue and the board will follow the company's disciplinary procedures as usual."
Hamutenya previously served as Namibia's diamond commissioner before his move to Namdia as the chief executive in 2017.
His contract with Namdia will expire in June 2022.
