PROSPECTUS

CNS PHARMACEUTICALS, INC.

Up to 9,793,479 Shares of Common Stock

This prospectus relates to the resale, from time to time, by the selling shareholders (the “Selling Shareholders”) identified in this prospectus under the caption “Selling Shareholders,” of up to 9,793,479 shares of our common stock. The 9,793,479 shares of common stock offered for resale hereby consist of (i) 650,000 shares of our common stock purchased by the Selling Shareholders, and (ii) 9,143,479 shares of common stock issuable upon exercise of pre-funded common stock purchase warrants (the “Pre-Funded Warrants”) purchased by the Selling Shareholders. Subject to certain ownership limitations, the Pre-Funded Warrants are exercisable immediately for one share of common stock at an exercise price of $0.001 per share and have no expiration date, remaining exercisable until exercised in full. See “Prospectus Summary – May Private Placement” for additional information regarding the private placement transaction pursuant to which the shares of common stock and Pre-Funded Warrants were acquired.

We are registering the resale of the shares of common stock and the shares of common stock issuable upon exercise of the Pre-Funded Warrants on behalf of the Selling Shareholders, to be offered and sold by the Selling Shareholders from time to time.

We are not selling any shares of common stock under this prospectus and will not receive any proceeds from the sale by the Selling Shareholders of such shares. We are paying the cost of registering the shares of common stock covered by this prospectus as well as various related expenses. Each Selling Shareholder is responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of its shares.

Our common stock is listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol “CNSP.” On May 22, 2026, the closing price of the common stock, as reported on Nasdaq, was $5.42 per share. There is no established public trading market for the Pre-Funded Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Pre-Funded Warrants on any national securities exchange.

You should read this prospectus, together with additional information described under the headings “Incorporation of Certain Information by Reference” and “Where You Can Find More Information,” carefully before you invest in any of our securities.

Investing in our securities involves a high degree of risk. See the section entitled ”Risk Factors” beginning on page 5 of this prospectus for a discussion of risks that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is May 26, 2026

ABOUT THIS PROSPECTUS

This prospectus is part of the registration statement that we filed with the Securities and Exchange Commission (the “SEC”) pursuant to which the Selling Shareholders named herein may, from time to time, offer and sell or otherwise dispose of the shares of our common stock covered by this prospectus.

Our Company

We are a biotechnology company organized as a Nevada corporation in July 2017. In March 2026, we announced a new corporate strategy focused on developing innovative therapies for serious diseases. We are leveraging our executive team’s multi-functional experiences across high-value therapeutic areas to execute our new corporate strategy, which also includes pivoting from a singular focus on glioblastoma multiforme and exploring out-licensing opportunities for our legacy assets TPI 287 and Berubicin for which we have intellectual property rights under license agreement with Cortice Biosciences, Inc. and own pursuant to a collaboration and asset purchase agreement with Reata Pharmaceuticals.

Recent Developments - May Private Placement

On May 4, 2026, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with the Selling Shareholders for the private placement of (i) 650,000 shares of our common stock at $2.30 per share, and (ii) Pre-Funded Warrants to purchase 9,143,479 shares of common stock at a purchase price of $2.299 per Pre-Funded Warrant (the “Private Placement”).

Subject to certain ownership limitations, the Pre-Funded Warrants are exercisable immediately at an exercise price of $0.001 per share (subject to adjustment) and remain exercisable until exercised in full. A holder may not exercise any Pre-Funded Warrant to the extent that, after giving effect to such exercise, the holder and its affiliates would beneficially own more than 4.99% (or 9.99%, as applicable) of the total number of shares of our common stock outstanding immediately after giving effect to the exercise, which percentage may be increased or decreased at the holder’s election not to exceed 9.99%.

The closing of the Private Placement occurred on May 5, 2026 (the “Closing Date”). We received gross proceeds of approximately $22.5 million, before deducting placement agent fees and other offering expenses, and intend to use the net proceeds to identify, acquire and advance new assets and for working capital and general corporate purposes.

In connection with the Purchase Agreement, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Selling Shareholders pursuant to which we agreed to file a registration statement (the “Registration Statement”) registering the resale of the shares of Common Stock and the shares of Common Stock issuable upon exercise of the Pre-Funded Warrants within 15 days following the Closing Date, and to use our best efforts to cause the Registration Statement to be declared effective by the SEC within 60 days following its filing (or 90 days if reviewed by the SEC).

With limited exceptions, we have agreed not to enter into or announce any transaction for the sale of any of our equity securities or securities convertible into our equity securities for a period of 120 days from the effective date of this registration statement. In addition, we have agreed not to effect or enter into an agreement to effect any issuance of our common stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until one year after the Closing Date; provided that after 120 days from the effective date of the Registration Statement, we will be permitted to make sales under any “at-the-market offering” sales agreement with AGP (as defined below).

On May 4, 2026, we entered into a placement agency agreement (the “Placement Agreement”) with A.G.P./Alliance Global Partners (the “Placement Agent” or “AGP”), pursuant to which we paid the Placement Agent a cash fee equal to 7.0% of the gross proceeds from the Private Placement and reimbursed the Placement Agent for $75,000 of fees and expenses and $15,000 of non-accountable expenses.

We are filing the registration statement of which this prospectus forms a part in order to satisfy our obligations to the Selling Shareholders under the Registration Rights Agreement. The registration statement registers the resale by the Selling Shareholders of the shares of common stock issued in the Private Placement and the shares of common stock issuable upon exercise of the Pre-Funded Warrants. We will not receive any proceeds from the resale of these shares by the Selling Shareholders, although we may receive nominal proceeds upon any cash exercise of the Pre-Funded Warrants.

Risks Affecting Our Company

In evaluating an investment in our securities, you should carefully read this prospectus and especially consider the factors incorporated by reference in the sections titled “Risk Factors” commencing on page 5 of this prospectus and our Annual Report on Form 10-K, as amended, for the year ended December 31, 2025, incorporated by reference herein.

THE OFFERING

Common stock offered by Selling Shareholders:		Up to 9,793,479 shares of Common Stock (consisting of (i) 650,000 shares of our common stock outstanding and held by the Selling Shareholders, (ii) 9,143,479 shares of common stock issuable upon exercise of Pre-Funded Warrants).

Shares of common stock outstanding as of May 14, 2026:		1,461,449

Use of proceeds:		We will not receive any of the proceeds from any sale of shares of common stock by the Selling Shareholders. We will receive nominal proceeds only upon any cash exercises of the Pre-Funded Warrants, if any. See “Use of Proceeds.”

Risk factors:		An investment in our securities involves substantial risk. You should read carefully the “Risk Factors” section on page 5 of this prospectus, and under similar headings in the other documents incorporated by reference into this prospectus. Additional risks and uncertainties not presently known to us or that we currently deem to be immaterial may also impair our business and operations.

Nasdaq Capital Market symbol:		Our common stock is listed on The Nasdaq Capital Market under the symbol “CNSP”. There is no established public trading market for the Pre-Funded Warrants, and a market will likely never develop. The Pre-Funded Warrants are not and will not be listed for trading on the Nasdaq Stock Market, any other national securities exchange or other nationally recognized trading system.

The number of shares of common stock outstanding is based on 1,461,449 shares outstanding as of May 14, 2026, and excludes the 9,143,479 shares issuable upon exercise of the Pre-Funded Warrants, as well as:

	·	333,930 shares of common stock underlying outstanding warrants at a weighted average exercise price of $90.72 per share;

	·	14,961 shares of common stock underlying outstanding options with a weighted average exercise price of $3,289.55 per share, which options vest over a three to four-year period;

	·	57,017 shares of common stock underlying Restricted Stock Units which vest over a four-year period and Performance Units which vest based on our performance against predefined share price targets and the achievement of Positive Interim, Clinical Data as defined by the Board; and

	·	38,200 shares available for future issuance under the CNS Pharmaceuticals, Inc. 2020 Stock Plan.

Except as otherwise indicated, the information in this prospectus assumes no exercise of options or exercise of warrants.

RISK FACTORS

Before making an investment decision, in addition to the risks set forth below, you should consider the “Risk Factors” included under Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2025, and in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026, and in our updates to those Risk Factors which are incorporated by reference in this prospectus, as updated by our future filings with the SEC. The market or trading price of our common stock could decline due to any of these risks. In addition, please read “Cautionary Note Regarding Forward-Looking Statements” in this prospectus, where we describe additional uncertainties associated with our business and the forward-looking statements included or incorporated by reference in this prospectus. Please note that additional risks not currently known to us or that we currently deem immaterial may also impair our business and operations.

Risks Related to this Offering

The number of shares being registered for resale is significant in relation to the number of our outstanding shares of common stock.

We have filed a registration statement of which this prospectus is a part to register the shares offered hereunder for sale into the public market by the Selling Shareholders. These shares represent a significant number of shares of our common stock relative to our outstanding shares. The sale of all or a substantial portion of these shares in the market within a short period of time could adversely affect the market price of our common stock during the period the registration statement remains effective and could also adversely affect our ability to raise equity capital.

The exercise of the Pre-Funded Warrants and the subsequent resale of the underlying shares could result in substantial dilution and further pressure on the market price of our common stock.

The shares of common stock issuable upon exercise of the Pre-Funded Warrants registered for resale under this prospectus represent a substantial number of additional shares that may be issued and sold into the public market. The Pre-Funded Warrants are exercisable at a nominal exercise price and have no expiration date, which may incentivize holders to exercise the Pre-Funded Warrants and sell the underlying shares when market conditions permit. To the extent that these Pre-Funded Warrants are exercised and the underlying shares are sold, holders may experience dilution in their ownership interests, and the availability of a significant number of additional shares for resale could adversely affect the market price of our common stock.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the information in this prospectus, and the documents we incorporate by reference, contain forward-looking statements within the meaning of the federal securities laws. You should not rely on forward-looking statements in this prospectus, and the documents we incorporate by reference. Forward-looking statements typically are identified by use of terms such as “anticipate,” “believe,” “plan,” “expect,” “future,” “intend,” “may,” “will,” “should,” “estimate,” “predict,” “potential,” “continue,” and similar words, although some forward-looking statements are expressed differently. This prospectus, and the documents we incorporate by reference, may also contain forward-looking statements attributed to third parties relating to their estimates regarding the markets we may enter in the future. All forward-looking statements address matters that involve risk and uncertainties, and there are many important risks, uncertainties and other factors that could cause our actual results to differ materially from the forward-looking statements contained in this prospectus, and the documents we incorporate by reference.

Forward-looking statements include, but are not limited to, statements about:

	·	our ability to secure rights to new pipeline assets via in-licensing, acquisition or collaboration;

	·	our ability to obtain additional funding to develop our product candidates;

	·	our ability to maintain compliance with the NASDAQ Capital Market’s continued listing requirements, including any new continued listing requirements that are approved in the future;

	·	the need to obtain regulatory approval of our product candidates;

	·	the success of our clinical trials through all phases of clinical development;

	·	compliance with obligations under intellectual property licenses with third parties;

	·	any delays in regulatory review and approval of product candidates in clinical development;

	·	our ability to commercialize our product candidates;

	·	market acceptance of our product candidates;

	·	competition from existing products or new products that may emerge;

	·	potential product liability claims;

	·	our dependency on third-party manufacturers to supply or manufacture our products;

	·	our ability to establish or maintain collaborations, licensing or other arrangements;

	·	our ability and third parties’ abilities to protect intellectual property rights;

	·	our ability to adequately support future growth; and

	·	our ability to attract and retain key personnel to manage our business effectively.

You should also carefully consider the statements under “Risk Factors” and other sections of this prospectus, which address additional facts that could cause our actual results to differ from those set forth in the forward-looking statements. We caution investors not to place significant reliance on the forward-looking statements contained in this prospectus, and the documents we incorporate by reference. We undertake no obligation to publicly update or review any forward-looking statements, whether as a result of new information, future developments or otherwise.

USE OF PROCEEDS

All shares of our common stock offered by this prospectus are being registered for the account of the Selling Shareholders identified herein. We will not receive any of the proceeds from the sale of these shares.

We will receive proceeds from any cash exercise of the Pre-Funded Warrants, which, if exercised in cash with respect to all of the 9,143,479 shares of common stock underlying the Pre-Funded Warrants, assuming all of the Pre-Funded Warrants are exercised for cash at the initial exercise price of $0.001 per share, would result in gross proceeds to us of a maximum of $9,143.48.

We intend to use any proceeds received by us from the cash exercise of the Pre-Funded Warrants for working capital and general corporate purposes. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from the cash exercise of the Pre-Funded Warrants. Accordingly, our management will have broad discretion in the timing and application of these proceeds.

The holders of the Pre-Funded Warrants may exercise the Pre-Funded Warrants at their own discretion and at any time and in accordance with the terms of the Pre-Funded Warrants. The Pre-Funded Warrants have no expiration date and remain exercisable until exercised in full. As a result, we cannot predict when or if the Pre-Funded Warrants will be exercised. In addition, the Pre-Funded Warrants are exercisable on a cashless basis. As a result, we may receive little or no cash proceeds from the exercise of the Pre-Funded Warrants.

SELLING SHAREHOLDERS

We are registering the shares of common stock in order to permit the Selling Shareholders to offer the shares for resale from time to time. Except for the ownership of the shares of common stock and Pre-Funded Warrants, the Selling Shareholders have not had any material relationship with us within the past three years.

The table below lists the Selling Shareholders and other information regarding the beneficial ownership of the shares of common stock by each of the Selling Shareholders. The second column lists the number of shares of common stock beneficially owned by each Selling Shareholder, based on its ownership of the shares of common stock and Pre-Funded Warrants, as of May 14, 2026, assuming exercise of the Pre-Funded Warrants held by the Selling Shareholder on that date, without regard to any limitations on exercise.

The third column lists the shares of common stock being offered by this prospectus by the Selling Shareholders.

In accordance with the terms of a registration rights agreement with the Selling Shareholders, this prospectus generally covers the resale of the sum of (i) the number of shares of common stock issued to the Selling Shareholders in the “Private Placement” described above and (ii) the maximum number of shares of common stock issuable upon exercise of Pre-Funded Warrants, determined as if the outstanding Pre-Funded Warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, without regard to any limitations on the exercise of the Pre-Funded Warrants. The fourth column assumes the sale of all of the shares offered by the Selling Shareholders pursuant to this prospectus.

Under the terms of the Pre-Funded Warrants, a Selling Shareholder may not exercise the Pre-Funded Warrants to the extent such exercise would cause such Selling Shareholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 4.99% or 9.99%, as applicable, of our then outstanding common stock following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise of such Pre-Funded Warrants which have not been exercised. The number of shares in the second and fourth columns do not reflect this limitation. The Selling Shareholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

	·	privately negotiated transactions;

	·	settlement of short sales;

	·	in transactions through broker-dealers that agree with the Selling Shareholders to sell a specified number of such securities at a stipulated price per security;

	·	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

	·	in distributions to members, limited partners or stockholders of the Selling Shareholders;

	·	a combination of any such methods of sale; or

	·	any other method permitted pursuant to applicable law.

The Selling Shareholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

The Selling Shareholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, by amending the list of Selling Shareholders to include the pledgee, transferee or other successors in interest as Selling Shareholders under this prospectus. The Selling Shareholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the Selling Shareholders for purposes of this prospectus.

Broker-dealers engaged by the Selling Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority (“FINRA”) Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities, and if such short sale shall take place after the date that this Registration Statement is declared effective by the Commission, the Selling Shareholders may deliver securities covered by this prospectus. The Selling Shareholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Shareholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Shareholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Shareholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the shares of Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the shares of Common Stock by the Selling Shareholders or any other person. We will make copies of this prospectus available to the Selling Shareholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
