Super Micro names Mark Long chief financial officer, replacing David Weigand
Long previously served as Western Digital's CFO from 2016 to 2019 and most recently worked as a principal at Prime Impact Capital

Super Micro Computer has named Mark Long as chief financial officer, effective immediately. David Weigand stopped serving in the role on October 14, 2026.
Long previously spent 2016 to 2019 as chief financial officer of Western Digital Corporation and most recently worked as a principal at Prime Impact Capital. His offer letter sets an annual base salary of $725,000, a sign-on bonus of $500,000 and a guaranteed annual cash bonus of $500,000.
The change follows a board committee review, run with attorneys from Cooley LLP and forensic accounting firm Secretariat Advisors, that found no evidence of misconduct by management or the board and said the audit committee had acted independently, according to Yahoo Finance. That same review found Weigand held primary responsibility for the company's prior reporting lapses, though it concluded those lapses did not stem from bad faith or improper motives, Yahoo Finance reported. Weigand had been chief financial officer since February 2021 and chief compliance officer since May 2018, according to a Super Micro filing with the Securities and Exchange Commission. After the review, Kenneth Cheung, formerly the company's vice president of finance, was named chief accounting officer, and Super Micro began searching for a new CFO, Yahoo Finance reported.
Super Micro's auditor resigned in 2024 and the company faced a potential Nasdaq delisting before regaining compliance with listing requirements, according to Fortune. That history has left investors and auditors watching finance leadership at the company more closely than they would a typical CFO change. Long's earlier stint as a public-company CFO at Western Digital gives him reporting experience that may bear on whether Super Micro's controls and disclosures are now fully repaired. The appointment also comes as the company ramps shipments of Nvidia's Vera Rubin NVL72 racks, a buildout phase that tends to draw scrutiny to working capital, revenue recognition and cost reporting, all of which fall to the incoming CFO.
