Context

• As a 10% owner (rather than an executive acting in a corporate role), this transaction reflects a large stakeholder disposition. The presence of a Rule 10b5‑1 plan indicates the sales were likely pre-arranged and routine; such plans reduce—but do not eliminate—interpretive weight of the sale. Sales alone are less informative than purchases about insider confidence; no motivation is implied by this factual report. Exhibit list includes a Power of Attorney (Exhibit 24).
