Shares of D-Wave Quantum Inc. (NASDAQ: QBTS) fell 1.2% in after-hours trading on Tuesday after the company announced the retirement of Chief Financial Officer John Markovich, effective September 2, 2026.
Greg Golkov, currently Senior Vice President of Finance, will assume the role of interim CFO and principal financial and accounting officer, the company said. D-Wave did not disclose the reasons for Markovich’s departure, stating it was not due to any disagreement over operations, accounting policies, financial statements, or internal controls.
Markovich played a key role in D-Wave’s public listing in 2022, during which the company raised over $900 million in capital. CEO Alan Baratz highlighted his contributions in a statement.
Golkov brings more than 25 years of finance and accounting experience, including prior roles as vice president and controller at Butterfly Network from October 2020 to March 2023 and senior vice president of finance at Kaseya from August 2018 to October 2020. He joined D-Wave in May 2023.
D-Wave operates as the sole quantum computing company offering a dual-platform approach, combining annealing and gate-model systems with associated software and services.
