Item 5.08. Shareholder Director Nominations.

Rescheduling of 2026 Annual Meeting of Stockholders

On October 22, 2026, the Company entered into an amendment and restatement of the Transaction Agreements with the Purchasers. As a result, the Company's Board of Directors has rescheduled the Original Annual Meeting and now expects to hold its 2026 annual meeting of stockholders (the "Annual Meeting") on December 2, 2026 and expects the record date for the Annual Meeting to be October 28, 2026. The Company will provide additional details regarding the exact time and location of, and the matters to be voted on at, the Annual Meeting in the Company's proxy statement for the Annual Meeting, which will be filed with the SEC and mailed to stockholders.

Any proxy cards, telephone votes or internet votes that were submitted by stockholders for the Original Annual Meeting are void and will not count at the Annual Meeting. Stockholders will receive new proxy materials, including new proxy cards, new control numbers and new voting instructions for the Annual Meeting.

Stockholder Proposal and Director Nomination Deadlines

Because the scheduled date of the Annual Meeting represents a change of more than 30 days from the anniversary of the Company's 2025 annual meeting of stockholders, the deadlines for stockholders to propose actions for consideration or to nominate individuals to serve as directors at the Annual Meeting previously set forth in the Company's 2025 proxy statement are no longer applicable. Therefore, the Company is providing notice of revised deadlines in connection with the Annual Meeting as set forth below.

Revised Deadline for Rule 14a-8 Stockholder Proposals

Qualified stockholder proposals made pursuant to Rule 14a-8 ("Rule 14a-8") of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to be presented at the Annual Meeting and included in the Company's proxy statement and form of proxy relating to that meeting must be received by the Company no later than October 30, 2026, which the Company has determined to be a reasonable time before it expects to begin distributing its proxy materials for the Annual Meeting. Any proposal received after such date will be considered untimely for inclusion in the proxy statement. All proposals submitted pursuant to Rule 14a-8 must comply with the rules and regulations promulgated by the SEC.

Revised Deadline Under Advance Notice Bylaw Provision

The Company's Amended and Restated Bylaws (the "Bylaws") include separate advance notice provisions applicable to stockholders desiring to bring nominations for directors or to bring proposals before an annual meeting of stockholders other than pursuant to Rule 14a-8. These advance notice provisions require that, among other things, stockholders give timely written notice to the Company regarding such nominations or proposals and provide the information and satisfy the other requirements set forth in the Bylaws. To be timely, a stockholder who intends to present nominations or a proposal at the Annual Meeting other than pursuant to Rule 14a-8 must provide the information set forth in the Bylaws to the Company no later than November 2, 2026.

Revised Deadline Under Universal Proxy Rules

In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than November 2, 2026, which is the later of 60 calendar days prior to the date of the Annual Meeting and the 10th calendar day following public announcement by the Company of the date of the Annual Meeting.

Requirements Applicable to All Proposals

All stockholder proposals or notices provided in compliance with the foregoing deadlines must be received at the Company's headquarters and addressed to: Expion Energy, Inc., 2025 SW Deerhound Avenue, Redmond, Oregon 97756, Attention: Chief Financial Officer.

The Company reserves the right to reject, rule out of order, or take other appropriate action with respect to any nomination or proposal that does not comply with these and other applicable requirements.
