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

As previously disclosed, on May 1, 2026, Polar Power, Inc. (the “Company”) received a deficiency letter from the staff (the “Staff”) of the Nasdaq Stock Market (“Nasdaq”) stating that the Company was not in compliance with Nasdaq Listing Rule 5550(b) (the “Rule”) because it reported only $144,000 in stockholders’ equity as of December 31, 2025 in its 10-K for the year then ended.

The Company submitted a compliance plan with Nasdaq on June 15, 2026, outlining specific measures that the Company intends to take to regain and maintain compliance with the Rule including, among other things, planned upcoming financing activities and an internal restructuring. The Company provided financial information demonstrating its ability to regain compliance.

On June 29, 2026, the Company received a letter from the Staff granted the Company an extension of time to regain compliance with the Rule. The terms of the extension are as follows: on or before October 28, 2026, the Company must opt for one of the two following alternatives to evidence compliance with the Rule: (A) the Company must furnish to the SEC and Nasdaq a publicly available report (e.g., a Form 8-K or Form 6-K) including: (1) a disclosure of Staff’s deficiency letter and the specific deficiency(ies) cited; (2) a description of the completed transaction or event that enabled the Company to satisfy the stockholders’ equity requirement for continued listing; (3) an affirmative statement that, as of the date of the report, the Company believes it has regained compliance with the stockholders’ equity requirement based upon the specific transaction or event referenced in Step 2; and (4) a disclosure stating that Nasdaq will continue to monitor the Company’s ongoing compliance with the stockholders’ equity requirement and, if at the time of its next periodic report the Company does not evidence compliance, that it may be subject to delisting, or (B) the Company must furnish to the SEC and Nasdaq a publicly available report including: (1) steps 1 & 2 set forth above; (2) a balance sheet no older than 60 days with pro forma adjustments for any significant transactions or event occurring on or before the report date. The pro forma balance sheet must evidence compliance with the stockholders’ equity requirement; and (3) a disclosure that the Company believes it also satisfies the stockholders’ equity requirement as of the report date and that Nasdaq will continue to monitor the Company’s ongoing compliance with the stockholders’ equity requirement and, if at the time of its next periodic report the Company does not evidence compliance, that it may be subject to delisting.

Regardless of which alternative the Company chooses, if the Company fails to evidence compliance upon filing its periodic report for the year ending December 31, 2026, with the SEC and Nasdaq, the Company may be subject to delisting. In the event the Company does not satisfy these terms, Nasdaq will provide written notification that its securities will be delisted. At that time, the Company may appeal Nasdaq’s determination to a Hearings Panel.
