Shares of 23andMe Holding Co. /zigman2/quotes/222659849/composite ME -4.35% were falling more than 7% in premarket trading Friday after the DNA-testing company disclosed that Chief Financial Officer Stevem Schoch was resigning from the company. He will stop being 23andMe's "principal financial officer and principal accounting officer" as of Sept. 1, though he intends to stay with the company through Sept. 30 to help with the transition. The resignation "is not the result of any dispute or disagreement with the Company, including any matters relating to the Company's accounting practices or financial reporting," 23andMe said in a filing with the Securities and Exchange Commission. Joseph Selsavage will serve as 23andMe's interim chief financial and accounting officer. He is currently the chief financial officer of Lemonaid Health, which 23andMe acquired in November.
