An executive with COVID-19 vaccine maker Moderna resigned from the company about one day after taking the job, according to a statement Wednesday.

In the statement and in a securities filing, Moderna said that its new chief financial officer, Jorge Gomez, resigned on Tuesday, “effective immediately.” Retired Chief Financial Officer David Meline will continue his role starting May 11, said the firm.

“The announcement follows the May 10 public disclosure by Mr. Gomez’s former employer, Dentsply Sirona Inc., of an ongoing internal investigation into certain matters, including financial reporting,” Moderna’s statement said.

Gomez’s appointment was announced by the company in April and came into effect on Monday.

After leaving the company, Gomez will receive 12 months’ salary, totaling about $700,000, and he will forfeit his signing bonus and bonus eligibility, Moderna said in the securities filing.

The Dentsply Sirona Inc. investigation, which may cause a delay in the dental products maker’s quarterly filing with U.S. securities regulators, was focused on the use of incentives to sell products to distributors and whether those were properly accounted for. Dentsply last month fired its then-CEO Don Casey without disclosing a reason.

“The (board’s) audit committee has retained an independent outside counsel, which has engaged a forensic accounting firm, to assist in the investigation,” Dentsply said in a recent filing with the U.S. Securities and Exchange Commission. “The company has voluntarily contacted the SEC to advise it that an internal investigation is underway.”
