Insights

Securities Compliance Counsel

Form 144 lists multiple proposed affiliate sales and broker details.

The filing records proposed dispositions of common stock with dated sale lines from 12/16/2025 to 03/02/2026, and lists Morgan Stanley Smith Barney LLC as the executing broker. These are notices of proposed sales, not confirmations of settlement.

Cash‑flow treatment is implicit in the listed amounts; timing and actual execution depend on market transactions and compliance with Section 144 conditions.

Equity Markets Analyst

Multiple small-to-moderate sale lines are shown, including a 6,015-share line.

The record shows repeated 1,200-share lines on several dates and a 6,015-share line dated 12/16/2025 with corresponding dollar amounts (for example $1,155,337.74). These entries suggest staged disposition activity by an affiliate.

Actual market impact depends on execution method and whether sales occurred as proposed; subsequent filings would show executed trades.
