Arcadia Biosciences, Inc.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. On August 31, 2026, Arcadia Biociences, Inc. (the "Company") received an expected letter (the “Letter”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that its stockholders’ equity, as reported in its Quarterly Report on Form 10-Q for the period ended June 30, 2026 (the “Form 10-Q”), did not meet the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires that a listed company’s stockholders’ equity be at least $2,500,000 (the “Stockholders’ Equity Requirement”). In the Form 10-Q, the Company reported stockholders’ equity as of June 30, 2026, of $633,000, which is below the minimum stockholders’ equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1). The Letter also noted that the Company does not meet the alternatives of market value of listed securities or net income from continuing operations, and therefore, the Company no longer complied with Nasdaq’s listing rules. The Letter has no immediate impact on the listing of the Company’s common stock on the Nasdaq Capital Market, which will continue to be listed and traded on the Nasdaq Capital Market, subject to the Company’s compliance with the other continued listing requirements. Under Nasdaq Listing Rules, the Company has 45 calendar days, or until October 15, 2026, to provide Nasdaq with a plan to achieve and sustain compliance. The Company is currently evaluating various alternatives and intends to timely submit a plan to Nasdaq to regain compliance with the Stockholders’ Equity Requirement. If Nasdaq accepts the Company’s plan to regain compliance, Nasdaq may grant an extension of up to 180 calendar days from the date of the Letter to evidence compliance. There can be no assurance that Nasdaq will accept the Company’s plan, if submitted, to regain compliance with the Stockholders’ Equity Requirement or, if accepted, that the Company will evidence compliance with the Stockholders’ Equity Requirement during any extension period that Nasdaq may grant. If Nasdaq does not accept the Company’s plan, the Company will have the opportunity to appeal that decision to a Nasdaq Hearings Panel pursuant to Nasdaq Listing Rule 5815(a). Such a hearing request ordinarily stays any suspension or delisting action based on the circumstances described in this Letter pending the issuance of a written panel decision. However, there can be no assurance that such appeal would be successful. The Company, by filing this Form 8-K, discloses its receipt of the notification from Nasdaq in accordance with Listing Rule 5810(b). Forward Looking Statements This Current Report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995.
