Form 144 — notice of proposed sale of securities
Actionable Insight • Neutral

This single Form 144 is routine and not material on its own. However, the cumulative insider selling pattern (10 sells totaling $1.7M in 30 days) is worth monitoring. Watch for any upcoming earnings or material events that might explain the selling.

Executive Summary

Laura Francis, a director of SI-Bone, filed a Form 144 notice of intent to sell 3,923 shares of common stock, with an estimated aggregate market value of approximately $76,420.
