Pre-Arranged Trading Plan (Rule 10b5-1)

As noted in footnote 1, all sales were executed under a Rule 10b5-1 trading plan adopted on March 2, 2026. Such plans allow corporate insiders to set up a predetermined schedule for selling company stock, mitigating concerns regarding discretionary trading based on material non-public information.

Ownership Context and Market Impact

• Pre-Transaction Direct Holdings: 1,308,672 shares
• Post-Transaction Direct Holdings: 1,290,672 shares
• Percentage Disposed: The 18,000 shares sold represent roughly 1.38% of Eisen's direct holding prior to the transactions.

Because the sale was executed under a previously established Rule 10b5-1 plan and represents only a minor reduction in the insider's substantial 1.29M+ share position, the market significance is considered Low.
