Context
As a 10% owner, Ms. Gallup is a major shareholder rather than necessarily a company executive; these sales were carried out under a pre-established 10b5‑1 plan, which is a common mechanism for scheduled, pre-authorized dispositions. Sales under 10b5‑1 plans are often routine and do not, by themselves, indicate management sentiment; the filing is factual and does not explain motivation.
