Notice-and-Access regulatory

"Notice-and-Access: Registered Shareholders: YES Beneficial Holders: YES"

A notice-and-access delivery model sends shareholders a short notice telling them where to find full proxy materials and other corporate documents online instead of receiving bulky paper copies by mail. For investors it matters because it speeds delivery and cuts costs for companies, but also shifts responsibility onto shareholders to retrieve and read the materials before voting or making decisions—like getting a postcard with a link to the full report rather than the report itself.

Beneficial Ownership Determination Date regulatory

"Beneficial Ownership Determination Date: May 4, 2026"

Non-Objecting Beneficial Owners regulatory

"Reporting issuer is sending proxy-related materials directly to Non-Objecting Beneficial Owners: YES"

Non-objecting beneficial owners are individual or institutional shareholders who hold stock through a broker or bank and have allowed that intermediary to share their name and contact details with the company that issued the shares. This matters to investors because it lets companies contact those shareholders directly about votes, proxy materials, tender offers or corporate updates, which can speed communication and influence participation much like a sender getting permission to mail you directly rather than through a forwarding service.

Objecting Beneficial Owners regulatory

"Issuer paying for delivery to Objecting Beneficial Owners: YES"
