Quantum Computing (QUBT) CFO Christopher Roberts Exercises Options, Sells Shares

What Happened

Christopher Bruce Roberts, CFO and General Counsel of Quantum Computing Inc. (QUBT), exercised 400,000 stock options on March 10, 2026 at an exercise price of $6.85 (total cost $2,740,000) and subsequently sold 78,262 of the resulting shares in open-market transactions for approximately $614,500 (weighted-average sale price $7.85). The filings show the option exercise/conversion (Form 4 code M) and two sales (codes S) on March 10 and March 11, 2026.
These actions were part of a broker-assisted cashless exercise: shares were sold to cover the exercise price, withholding taxes, and broker fees.

Context

This was an option exercise with partial immediate sale (cashless exercise). The exercise created the shares (conversion of derivatives to stock) and a portion was sold to cover costs—common for option holders exercising vested awards.
Sales to cover taxes/fees are routine and do not necessarily indicate a change in insider sentiment. Purchases would be a clearer bullish signal; here the net effect was acquisition via exercise offset by partial sale for cashless settlement.
