IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE

STOCKHOLDER MEETING TO BE HELD ON WEDNESDAY, OCTOBER 14, 2026

The Company’s Proxy Statement and Annual Report are available on our website athttps://ir.polarpower.com/annual-meeting. You are encouraged to access and review all of the important information contained in the proxy materials before voting.

What items will be voted on at the Annual Meeting?

Stockholders will vote on eight items at the Annual Meeting:

What are the Board’s Voting Recommendations?

The Board recommends that you vote your shares a “FOR” all of the Director Nominees, “FOR” two years on the Say on Pay Frequency Proposal, and “FOR” each of the other proposals.

Who is entitled to vote?

To be able to vote, you must have been a stockholder on September 9, 2026, the record date for determination of stockholders entitled to notice of and to vote at the Annual Meeting. As of the record date, 4,309,319 shares of our voting common stock and 1,611 shares of our voting Series A Preferred were outstanding.

How many votes do I have?

Holders of common stock and Series A Preferred will vote at the Annual Meeting on all matters. Each holder of common stock is entitled to one vote per share held. Holders of Series A Preferred generally are entitled to vote on all matters on which holders of common stock are entitled to vote, on an as-converted-to-common-stock basis (not to exceed the beneficial ownership limitation as described below), except on Proposal Three. As a result, a total of 5,265,881 votes may be cast at the Annual Meeting.

What is a quorum?

For business to be conducted at the Annual Meeting, a quorum must be present. The presence at the Annual Meeting, either in person or by proxy, of holders of shares of outstanding common stock and preferred stock entitled to vote and representing at least a majority of our outstanding voting power will constitute a quorum for the transaction of business. Accordingly, shares representing 2,632,941 votes must be present in person or by proxy at the Annual Meeting to constitute a quorum.

Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present for the transaction of business.

If a quorum is not present, the Annual Meeting will be adjourned until a quorum is obtained.

What are abstentions and broker non-votes?

An “abstention” is the voluntary act of not voting by a stockholder who is present at a meeting in person or by proxy and entitled to vote. “Broker non-votes” refers to shares held by a brokerage firm or other nominee (for the benefit of its client) that are represented at the meeting, but with respect to which such broker or nominee is not instructed to vote on a particular proposal and does not have discretionary authority to vote on that proposal.

If you are a beneficial owner whose shares are held in street name and you do not submit voting instructions to your broker, your broker may generally vote your shares in its discretion on routine matters. We believe that Proposals Two and Four are routine and may be voted on by your broker if you do not submit voting instructions. However, pursuant to rules of The Nasdaq Stock Market (“Nasdaq”), brokers do not have the discretion to vote their clients’ shares on non-routine matters, unless the broker receives voting instructions from the beneficial owner. All Proposals except Proposals Two and Four are considered non-routine matters. Consequently, if your shares are held in street name, you must provide your broker with instructions on how to vote your shares in order for your shares to be voted on Proposals One, Three, Five, Six and Seven.

What are the general effects of abstentions and broker non-votes?

Brokers who hold shares for the accounts of their clients may vote such shares either as directed by their clients or in their own discretion as permitted under the Nasdaq Listing Rules. For purposes of the Annual Meeting, brokers or nominees are permitted to vote their clients’ proxies in their own discretion as to the ratification of the appointment of our independent registered public accounting firm and the adjournment, if the clients have not furnished voting instructions within 10 days of the meeting. Abstentions and broker non-votes will not be counted as a vote “for” or “against” any matter and accordingly will not affect the outcome with respect to any matter to be voted on at the Annual Meeting. The election of directors proposal is “non-discretionary” and brokers or nominees who have received no instructions from their clients do not have discretion to vote on those items.

Please note that brokers may not vote your shares on the election of directors or other non-routine matters in the absence of your specific instructions as to how to vote, thus we strongly encourage you to provide instructions to your broker regarding the voting of your shares you hold in “street name” or through a broker or other nominee.

What vote is required to approve each proposal?

While holders of Series A Preferred generally are entitled to vote on all matters on which holders of common stock are entitled to vote, on an as-converted-to-common-stock basis (not to exceed the beneficial ownership limitation as described below), voting together as a single class with the common stock, they are not entitled to vote any shares of Series A Preferred they hold, including on an as-converted-to-common-stock basis, on Proposal Three.

Proposal One

The six nominees receiving the highest number of affirmative votes of the voting power of the shares present at the Annual Meeting in person or represented by proxy and entitled to vote on the election of directors, will be elected as directors to serve until the next annual meeting of stockholders and/or until their successors are duly elected and qualified. Abstentions will have no effect on the outcome of the election of nominees for director. Should any nominee(s) become unavailable to serve before the Annual Meeting, the proxies will be voted by the proxy holders for such other person(s) as may be designated by our Board or for such lesser number of nominees as may be prescribed by the Board. Votes cast for the election of any nominee who has become unavailable will be disregarded.

Proposals Two, Four, Five and Seven

The affirmative vote of a majority of the voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter, is required for approval of Proposals Two, Four, Five and Seven. Broker non-votes, if any, will have no effect on the outcome of these proposals. However, broker non-votes are not expected on Proposals Two and Four because they are considered routine matters under NYSE rules, meaning brokers may vote uninstructed shares in their discretion. Abstentions will be counted toward the tabulation of votes present or represented on these proposals and will have the same effect as votes against these proposals.

Proposal Three

The affirmative vote of a majority of the voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter, is required for approval of this proposal, provided that, the stockholders of shares of Series A Preferred are not entitled to vote such shares upon this proposal. Broker non-votes, if any, will have no effect on the outcome of these proposals. Abstentions will be counted toward the tabulation of votes present or represented on these proposals and will have the same effect as votes against these proposals.

Proposal Six

For purposes of the advisory vote regarding the frequency of the advisory vote on executive compensation, the option of every year, every two years or every three years that receives the highest number of votes cast by stockholders will be the frequency for the advisory vote on executive compensation that has been selected by stockholders. Abstentions and broker non-votes will not be counted as votes cast and accordingly, will not have an effect on Proposal Seven. The proxy card provides stockholders with four choices (every year, every two years, every three years, or abstain). Stockholders are not voting to approve or disapprove our Board’s recommendation. Proxies submitted without direction pursuant to this solicitation will be voted to hold a say-on-pay vote every two years.

How do I vote?

If you are a “registered holder,” that is, your shares are registered in your own name through our transfer agent, and you are viewing this proxy over the Internet you may vote electronically over the Internet. For those stockholders who receive a paper proxy in the mail, you may also vote electronically over the Internet or by email, or by completing and mailing the proxy card provided. The website identified in our proxy card provides specific instructions on how to vote electronically over the Internet. Those stockholders who receive a paper proxy by mail, and who elect to vote by mail, should complete and return the mailed proxy card in the addressed, postage paid envelope that was enclosed with the proxy materials.

If your shares are held in “street name,” that is, your shares are held in the name of a brokerage firm, bank or other nominee, you will receive instructions from your record holder that must be followed for your record holder to vote your shares per your instructions. If you receive paper copies of our proxy materials from your brokerage firm, bank or other nominee, you will also receive a voting instruction form. Please complete and return the enclosed voting instruction form in the addressed, postage paid envelope provided.

Stockholders who have previously elected to access our proxy materials and annual report electronically over the Internet will continue to receive an email, referred to in this Proxy Statement as an email notice, with information on how to access the proxy information and voting instructions.

Only proxy cards and voting instruction forms that have been signed, dated and timely returned, and only shares that have been timely voted electronically, by mail or by email will be counted in the quorum and voted.The Internet voting facilities will close at 11:59 p.m. Eastern Time, Tuesday, October 13, 2026 for shares held directly and at 11:59 p.m. Eastern Time, Monday, October 12, 2026 for shares held in a plan.

Stockholders who vote over the Internet or by email need not return a proxy card or voting instruction form by mail, but may incur costs, such as usage charges, from Internet service providers. You may also vote your shares in person at the Annual Meeting. If you are a registered holder, you may request a ballot at the Annual Meeting. If your shares are held in street name and you wish to vote in person at the meeting, you must obtain a proxy issued in your name from the record holder (e.g., your broker) and bring it with you to the Annual Meeting. We recommend that you vote your shares in advance as described above so that your vote will be counted if you later decide not to attend the Annual Meeting.

What if I receive more than one email notice, proxy card or voting instruction form?

If you receive more than one email notice, proxy card or voting instruction form because your shares are held in multiple accounts or registered in different names or addresses, please vote your shares held ineach account to ensure that all of your shares will be voted.

Who will count the votes and how will my vote(s) be counted?

All votes will be tabulated by the inspector of elections appointed for the Annual Meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

If your proxy is properly submitted, the shares represented thereby will be voted at the Annual Meeting in accordance with your instructions. If you are a registered holder and you do not specify how the shares represented thereby are to be voted, your shares will be voted “FOR” the election of each of the six nominees to our Board listed in this Proxy Statement and “FOR” the approval of Proposals Two to Five and Seven, and every “Two Years” for Proposal Six, and in the discretion of the proxy holder(s) as to any other matters that may properly come before the Annual Meeting or any adjournment(s) or postponement(s) of the Annual Meeting, as well as any procedural matters. If your shares are held in street name and you do not specify how the shares represented thereby are to be voted, your broker may exercise its discretionary authority to vote on Proposals Two and Four.

Can I change my vote after I have voted?

If your shares are registered in your name, you may revoke or change your vote at any time before the Annual Meeting by voting again electronically over the Internet or by email, or by filing a notice of revocation or another proxy card with a later date with our Secretary at Polar Power, Inc., 249 E. Gardena Boulevard, Gardena, California 90248. If you are a registered stockholder and attend the Annual Meeting and vote by ballot, any proxy that you submitted previously to vote the same shares will be revoked automatically and only your vote at the Annual Meeting will be counted. If your shares are held in street name, you should contact the record holder to obtain instructions if you wish to revoke or change your vote before the Annual Meeting. Please note that if your shares are held in street name, your vote in person at the Annual Meeting will not be effective unless you have obtained and present a proxy issued in your name from the record holder.

Who will bear the cost of soliciting proxies?

We will bear the entire cost of soliciting proxies for the Annual Meeting, including the cost of preparing, assembling, printing and mailing this Proxy Statement, the proxy card and any additional solicitation materials furnished to our stockholders. Copies of solicitation materials will be furnished to brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward the solicitation materials to the beneficial owners. We may reimburse such persons for their reasonable expenses in forwarding solicitation materials to beneficial owners. The original solicitation of proxies may be supplemented by solicitation by personal contact, telephone, facsimile, email or any other means by our directors, officers or employees, and we will reimburse any reasonable expenses incurred for that purpose. No additional compensation will be paid to those individuals for any such services.

The matters to be considered and acted upon at the Annual Meeting are referred to in the preceding notice and are discussed below more fully.
