Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On September 14, 2026, Fifth Era Acquisition Corp. I (the “Company”) received a written notice (the “Notice”) from the Nasdaq Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that the Company was not in compliance with Listing Rule 5450(a)(2), which requires the Company to have at least 400 Total Holders for continued listing on the Nasdaq Global Market (the “Minimum Total Holders Requirement”). The Notice is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company’s securities on Nasdaq Global Market.

The Notice states that the Company has 45 calendar days, or until October 29, 2026, to submit a plan to regain compliance with the Minimum Total Holders Requirement. If Nasdaq accepts the Company’s plan, Nasdaq may grant the Company an extension of up to 180 calendar days from the date of the Notice to evidence compliance with the Minimum Total Holders Requirement. If Nasdaq does not accept the Company’s plan, the Company will have the opportunity to appeal the decision in front of a Nasdaq Hearings Panel.

The Company will consider implementing available options to regain compliance with the Minimum Total Holders Requirement. Alternatively, the Company may consider applying to transfer its securities to The Nasdaq Capital Market.

This announcement is made in compliance with Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a deficiency notification.

Forward-Looking Statements

Certain information contained in this Current Report on Form 8-K consists of forward-looking statements that involve risks, uncertainties and assumptions that are difficult to predict. Words such as “must,” “will,” “may,” “intends,” and similar expressions, or the use of future tense, identify forward-looking statements, but their absence does not mean that a statement is not forward-looking. Such forward-looking statements are not guarantees of performance and actual actions or events could differ materially from those contained in such statements. For example, there can be no assurance that the Company will regain compliance with the Minimum Total Holders Requirement during the any applicable cure period or be able to transfer its securities to the Nasdaq Capital Market. Additional factors that could cause actual results to differ from the forward-looking statements herein include potential adverse effects on the Company’s business related to the disclosures made in this Current Report on Form 8-K, volatility of the Company’s stock price, and the other risk factors discussed under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 and the Company’s other filings with the Securities and Exchange Commission. The forward-looking statements contained in this Current Report on Form 8-K speak only as of the date of this report and the Company undertakes no obligation to publicly update any forward-looking statements to reflect changes in information, events or circumstances after the date of this report, unless required by law.
