D-Wave Quantum (NYSE:QBTS) stock is down 8% to $17.79 in midday trading Wednesday after the company disclosed its chief financial officer will retire next week. Also, IonQ (NYSE:IONQ | IONQ Price Prediction) shares are down 3% to $40.68, tracking the D-Wave headline as sentiment seems to sour on certain quantum-computing names.
The Defiance Quantum ETF (NASDAQ:QTUM) is down 0.4% to $148.27, barely reacting to the D-Wave move. Meanwhile, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is unchanged at $765.57. That gap between the cluster fund and its noisiest member frames today’s decline as a name-specific event.
D-Wave Quantum stock was down 26% year to date through Tuesday’s close, so today’s reaction lands on a name already under pressure this year. IonQ shares are also lower year-to-date, providing context for today’s sympathy move. D-Wave Quantum’s market capitalization sits at $6.57 billion, while IonQ’s market cap sits at $16.48 billion.
Catalyst: Markovich Retires Effective September 2
D-Wave Quantum announced on August 25 that CFO John Markovich is retiring and stepping down effective September 2. Greg Golkov, senior vice president of finance since May 2023, becomes acting chief financial officer and principal financial and accounting officer.
Golkov brings more than 25 years of finance and accounting experience, previously serving as vice president and controller at Butterfly Network and senior vice president of finance at Kaseya. His current remit at D-Wave Quantum already covers accounting, SEC reporting, financial planning and analysis, treasury and tax, so the internal handoff is coming from a familiar seat. Prior operating roles at technology and IT services businesses give Golkov experience relevant to D-Wave Quantum’s cloud-first commercial model.
D-Wave Quantum’s release stated explicitly that the resignation was not the result of any disagreement with the company on any matter relating to its business, operations, accounting policies, practices, financial statements, disclosure controls and procedures, or internal control over financial reporting. CEO Alan Baratz credited Markovich with a pivotal role in taking the company public in 2022, raising over $900 million in capital, and developing a path to profitability.
Why an Orderly CFO Change Is Sinking QBTS
The company is a pre-profit business with a $6.57 billion market capitalization built on future capital raises and future revenue conversion. The company is the only company offering both annealing and gate-model quantum computing systems, sells through the Leap quantum cloud service, professional services, and on-premises systems, and serves more than 100 organizations while holding over 290 U.S. granted patents.
At companies at this stage, the finance seat carries more weight than at a mature operator, because credibility around the path to profitability and the ability to execute additional financings run through it. D-Wave Quantum has stated there was no accounting or controls issue behind the change, so today’s response reads as sentiment around an unexpected leadership shift at a speculative name.
D-Wave Quantum’s Q2 2026 results underline why finance leadership matters at this stage. The company reported Q2 revenue of $3.08 million (missing the $4.03 million estimate), while remaining performance obligations reached $40.7 million, up 668% year over year.
IonQ’s own most recent quarter provides useful contrast on why the market reacts differently to different quantum names. IonQ reported Q2 2026 revenue of $80.05 million (beating the $66.42 million estimate) and raised its full-year 2026 outlook to $280 million to $290 million. That stronger fundamental profile helps explain why the sympathy move in IonQ stock is smaller than the primary reaction in D-Wave Quantum stock today.
Peer Reaction and Position Sizing
Other quantum names frequently trade alongside D-Wave and IonQ shares on quantum headlines, and remain part of the same speculative basket. The 3% slide in IonQ stock today, alongside a barely-moved Defiance Quantum ETF, is a reminder of how correlated the group remains, even when the trigger belongs to one company.
Rigetti Computing (NASDAQ:RGTI) stock is trading at $16.12, down 5%. Quantum Computing Inc. (NASDAQ:QUBT) stock is down only 1% to $8.35. Both names are lower on the session, but as you can see, the damage isn’t evenly spread.
For position sizing, investors holding D-Wave Quantum stock into this transition may want to keep their exposure modest until Golkov’s tenure produces a full quarterly close and an earnings call. D-Wave Quantum stock carries a beta of 2.16 and a 52-week range of $12.75 to $46.75, which argues for smaller position sizes than a mature technology name would warrant (we wrote a free playbook on sizing speculative bets to no more than 5% of a portfolio, here).
Investors can watch for signs that the acting CFO tag becomes permanent, which would remove one layer of uncertainty from this story. D-Wave Quantum’s next scheduled information point is the Q3 2026 earnings report, where management can address capital planning, the pace of bookings-to-revenue conversion, and the path to profitability under new finance leadership.
