Calista Compliance With State Proxy Regulations

April 27, 2026

Each year prior to Calista Corporation’s Annual Meeting of Shareholders, there is an exciting period during which solicitations are sought for Board of Director Candidates. Following that time there is a period when Calista Shareholders cast their votes up until the Annual Meeting. Calista encourages Shareholders to gather facts about the candidates by reviewing the 2026 Proxy Statement, learn about Calista’s financial performance by reviewing the 2025 Annual Report, and to review the qualifications and accomplishments of the Board-endorsed slate by going to www.calistacorp.com/vote-experience-shareholder-benefits.

The State of Alaska proxy regulations require tracking and reporting on a variety of issues during the solicitation and election periods, including postings on Calista social media pages.

During the solicitation period and through the Annual Meeting, Shareholders may post comments on Calista social media pages encouraging Shareholders to vote. We ask that all Shareholders keep their comments civil and respectful. Calista reserves the right to immediately delete any posts on its social media pages that contain obviously false or defamatory information, posts that are abusive, disrespectful or contain profanities, and to take down posts that are determined by legal counsel to be misleading.

Additionally, anyone who engages in Annual Meeting proxy solicitation online and/or to at least 30 resident Shareholders is responsible for complying with State of Alaska proxy regulations (3 AAC 08.307). This includes posting to social media pages.

Proxy regulations (under 3 AAC 08.307) require a person who posts or solicits proxy votes must file a copy of their material with the Alaska Administrator of Securities. Individuals may file their posts by e-mailing them in searchable PDF format to ancsa@alaska.gov.

Calista cannot provide legal advice, so if a Shareholder has any questions about the requirements of the State of Alaska proxy regulations, the Shareholder should consult with his or her attorney.

Starting on April 27, 2026, a proxy voting envelope with the official Proxy Form was sent to each eligible voting Calista Shareholder. In addition, a large envelope of Annual Meeting materials, including the 2026 Proxy Statement and 2025 Annual Report will be mailed separately to each Shareholder household (if you opted for electronic materials, look for your proxy voting email).

Starting April 27, any Shareholder can view the Annual Meeting materials online at www.CalistaVote.com.

Starting April 27, Calista encourages all eligible voting Shareholders to cast their proxy vote at www.CalistaVote.com, or use the official Proxy Form. Allow up to three weeks for mail to arrive.

The 2026 Annual Meeting of Shareholders is scheduled for June 5 in Bethel. Find more Annual Meeting details at www.calistacorp.com/AnnualMeeting.
