Context

• This filing concerns a 10% beneficial owner (an entity), not an individual officer or director. Sales by large holders can be for many reasons (liquidity, portfolio rebalancing, etc.) and should not be taken alone as a signal of company prospects. Retail investors may give more weight to insider purchases than routine institutional sales when assessing insider sentiment.
