In April, the dental products company Dentsply Sirona fired its CEO, Don Casey, and removed him from its board. Case had assumed the CEO role in February 2018.

Dentsply Sirona recently disclosed that it was investigating whether “former and current members of senior management” were involved in financial reporting fraud.

In particular, the company is seeking additional information on the use of incentives to market products to distributors and their role in achieving executive compensation targets in 2021.

Dentsply Sirona’s audit committee has obtained independent outside counsel, which, in turn, has enlisted a forensic accounting company to assist in the investigation, according to an SEC filing.

In December 2020, SEC settled charges against Dentsply Sirona for “failing to make certain required disclosures in periodic reports filed with the SEC.”

MRNA shares fell 2.51% to $129.00 in mid-day trading while Dentsply Sirona’s increased about 5% to $38.24.
