[Form 4] D-Wave Quantum Inc. Insider Trading Activity

Rhea-AI Filing Summary

D-Wave Quantum Inc. director John D. DiLullo sold 7,850 shares of Common Stock in an open-market transaction under a pre-arranged Rule 10b5-1 trading plan. The weighted average sale price was $24.43 per share, with individual trades between $23.33 and $26.28.

After the sale, DiLullo held 21,310 shares directly, which the filing notes includes 9,357 unvested restricted stock units. Because the trade was executed pursuant to a Rule 10b5-1 plan adopted in advance, the timing appears to reflect a scheduled diversification step rather than a discretionary market-timing decision.

Insights

Insider transactions analyst

Routine 10b5-1 plan sale by a director with meaningful remaining stake.

John D. DiLullo, a director of D-Wave Quantum Inc., executed an open-market sale of 7,850 Common Stock shares at a weighted average of $24.4343 per share. This was a straightforward non-derivative transaction, with no option exercises or conversions reported.

The filing specifies the sale occurred automatically under a Rule 10b5-1 trading plan adopted on June 15, 2025, indicating it was pre-scheduled rather than opportunistic. Following the sale, DiLullo directly held 21,310 shares, including 9,357 unvested restricted stock units, so he retains ongoing equity exposure.

Given the pre-planned nature, absence of derivative activity, and the continued holding of shares and RSUs, this looks like a routine portfolio management move. On its own, it does not materially alter the investment picture for D-Wave Quantum Inc., so the overall signal from this filing is neutral.
