Context

• This filing documents a straightforward open-market sale by a company director. Sales can reflect many non-investment reasons (portfolio rebalancing, personal liquidity needs, planned dispositions) and, by themselves, do not necessarily indicate a change in company prospects. Retail investors should consider this as one data point alongside other insider trades and company fundamentals.
