Jorge Gomez, who stepped into the role of CFO for Moderna May 9, is already out of a job.

The sudden departure was a result of an internal probe of financial reporting by Gomez’s former employer, Dentsply Sirona, American dental equipment manufacturer and dental consumables producer. Moderna is a Cambridge, Massachusetts-based pharmaceutical company and is one of three drug makers with approved COVID-19 vaccines in the U.S. Moderna announced Gomez left the job May 11.

Moderna cited “an ongoing internal investigation into certain matters” in its announcement. David Meline, who recently retired as CFO of Moderna, will resume the role, effective May 11, as the company searches for a replacement.

Dentsply Sirona announced it will be filing its Form 10-Q late as a result of the internal probe.

“The investigation is ongoing, and the company cannot predict the duration or outcome of the investigation,” stated an SEC filing from Dentsply Sirona. “As a result, the company has not yet finalized its financial statements or its assessment of the impact of the investigation on its historical financial statements or for the financial statements for the three months ended March 31, 2022, and is therefore unable to file the Form 10-Q on a timely basis.”
