Context

• These were sales, not purchases; sales under 10b5‑1 plans are typically prearranged and do not necessarily signal new insider views about the company.
• For retail investors, purchases by insiders are generally more informative as potential bullish signals; routine, preplanned sales are common for liquidity or diversification reasons.
• If you need the breakdown of each lot price or the post‑transaction ownership amount, the filer has committed to provide those details to the company, shareholders, or the SEC staff upon request.
