Context

• A 10b5-1 plan is a pre‑arranged trading program that allows insiders to sell shares at scheduled times; trades under such plans are often viewed as routine and reduce the likelihood the trade was made on material nonpublic information. Sales do not necessarily indicate negative views about the company; they can reflect diversification, tax planning, or other personal reasons.
