D-wave Quantum Inc (QBTS) SEC 13F Holdings (Q2 2026): Institutional Buyers & Sellers

D-Wave Quantum announced that its CFO, John Markovich, is retiring and stepping down effective September 2, 2026, after about five years in the job — a stretch that included taking the company public in 2022 and raising more than $900 million in capital. Greg Golkov, the company's senior VP of finance since May 2023 who already oversees accounting, SEC reporting, and financial planning, moves up into the acting CFO seat and becomes the company's principal financial and accounting officer. The filing goes out of its way to stress that his departure had nothing to do with any disagreement over operations, accounting policies, or internal controls.
