This prospectus relates to the offer and resale from time to time of up to 1,422,031 shares of our common stock, par value $0.0001 per share (the “common stock”) issuable upon (i) the exercise of common stock purchase warrants issued on July 25, 2024 (“July Warrants”) in a private placement pursuant to an engagement letter with Roth Capital Partners, LLC (the “July Placement Agent”) and a securities purchase agreement, dated as of July 24, 2024, by and among us and the purchasers named therein (the “July Purchase Agreement”) and (ii) the exercise of common stock purchase warrants issued on August 26, 2024 (“August Warrants”) in a private placement pursuant to an engagement letter with Ladenburg Thalmann & Co. Inc. (the “August Placement Agent”) and a securities purchase agreement, dated as of August 23, 2024, by and among us and the purchasers named therein (the “August Purchase Agreement”).

We are registering the 1,422,031 shares of our common stock on behalf of the selling securityholders identified in the “Selling Securityholders” section of this prospectus or their permitted pledgees, assignees and successors-in-interest (the “Selling Securityholders”) pursuant to the July Purchase Agreement and August Purchase Agreement. The Selling Securityholders may offer, sell or distribute the shares of our common stock in a number of different ways and at varying prices. We provide more information about how the Selling Securityholders may offer, sell or distribute the shares of our common stock in the section of this prospectus titled “Plan of Distribution” beginning on page 15. We will not receive any of the proceeds from the sale of shares of our common stock by the Selling Securityholders; however, we will receive proceeds from the exercise of any July Warrants and August Warrants for cash. We have paid or will pay the fees and expenses incident to the registration of the shares of our common stock for sale by the Selling Securityholders. The Selling Securityholders will bear all commissions, discounts, brokerage fees and similar expenses, if any, attributable to their sales of shares of our common stock.

Our common stock is listed on the Nasdaq Capital Market (“Nasdaq”) under the symbol “NUWE.” On August 27, 2024, the last reported sale price of our common stock on Nasdaq was $1.40 per share.

We are a “smaller reporting company” as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements. See “Prospectus Summary — Implications of Being a Smaller Reporting Company.” This prospectus complies with the requirements that apply to an issuer that is a smaller reporting company.

This registration statement (the “Registration Statement”) to which this prospectus relates registers the resale of a substantial number of shares of our common stock by the Selling Securityholders. Sales in the public market of a large number of shares of our common stock, or the perception in the market that holders of a large number of shares of our common stock intend to sell shares, could reduce the market price of our common stock.

An investment in our shares of common stock involves a high degree of risk. Before making any investment decision, you should carefully read the discussion of the material risks of investing in our shares of common stock in “Risk Factors” beginning on page 4 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission 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.

This prospectus is part of a registration statement on Form S-1 that we filed with the Securities and Exchange Commission (the “SEC”). The Selling Securityholders named in this prospectus may, from time to time, sell or otherwise distribute the shares of common stock offered by them as described in the section titled “Plan of Distribution” beginning on page 15 of this prospectus. We will not receive any of the proceeds from the sale of shares of our common stock by the Selling Securityholders; however, we will receive proceeds from the exercise of any July Warrants and August Warrants for cash. You should read this prospectus together with the more detailed information regarding the Company, our common stock, and our financial statements and notes to those statements that appear elsewhere in this prospectus and any applicable prospectus supplement together with the additional information that we incorporate in this prospectus by reference, which we describe under the heading “Where You Can Find More Information.”

Neither we nor the Selling Securityholders have authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus or any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. Neither we nor the Selling Securityholders take responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. The Selling Securityholders are offering to sell, and seeking offers to buy, shares of their common stock only in jurisdictions where it is lawful to do so.

We may also provide a prospectus supplement or post-effective amendment to the Registration Statement to add information to, or update or change information contained in, this prospectus. You should rely only on the information contained in, or incorporated by reference in, this prospectus and in any accompanying prospectus supplement. We have not authorized anyone to provide you with different information from that contained in, or incorporated by reference in, this prospectus. You should not assume that the information in this prospectus or any prospectus supplement is accurate as of any date other than the date on the front of those documents or that any document incorporated by reference is accurate as of any date other than its filing date. You should not consider this prospectus to be an offer or solicitation relating to the shares of common stock in any jurisdiction in which such an offer or solicitation relating to the shares of common stock is not authorized. Furthermore, you should not consider this prospectus to be an offer or solicitation relating to the shares of common stock if the person making the offer or solicitation is not qualified to do so, or if it is unlawful for you to receive such an offer or solicitation.

In this prospectus, we frequently use the terms “we,” “our,” “us,” “Nuwellis”, “Registrant,” and the “Company” to refer to Nuwellis, Inc.

All trademarks or trade names referred to in this prospectus are the property of their respective owners. Solely for convenience, the trademarks and trade names in this prospectus are referred to without the ® and ™ symbols, but such references should not be construed as any indicator that their respective owners will not assert, to the fullest extent under applicable law, their rights thereto. We do not intend the use or display of other companies’ trademarks and trade names to imply a relationship with, or endorsement or sponsorship of us by, any other companies.

An investment in our shares of common stock involves a high degree of risk. Before you invest you should carefully consider the risks and uncertainties described below, the “Risk Factors” section of our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024, each of which is incorporated by reference herein, and the other information in or incorporated by reference into this prospectus. Any of the risks and uncertainties set forth herein and therein could materially and adversely affect our business, financial condition, results of operations and prospects, which in turn could materially and adversely affect the trading price or value of our shares of common stock. Additional risks not currently known to us or which we consider immaterial based on information currently available to us may also materially adversely affect us. As a result, you could lose all or part of your investment.

The sale by the Selling Securityholders or an existing securityholder of a significant number of shares of common stock could have a material adverse effect on the market price of our common stock. In addition, the perception in the public markets that the Selling Securityholders or an existing securityholder may sell all or a portion of their shares of our common stock as a result of the registration of such shares for resale pursuant to this prospectus could also have a material adverse effect on the market price of our common stock. We cannot predict the effect, if any, that market sales of those shares of our common stock or the availability of those shares of common stock for sale will have on the market price of our common stock. To the extent that shares are sold into the market pursuant to the Registration Statement of which this prospectus forms a part, under Rule 144 or otherwise, particularly in substantial quantities, the market price of our common stock could decline.

Our common stock is listed on the Nasdaq Capital Market under the symbol “NUWE”. In order to maintain that listing, we must satisfy minimum financial and other requirements including, without limitation, the minimum stockholders’ equity requirement and the minimum bid price requirement. There can be no assurances that we will be successful in maintaining, or if we fall out of compliance, in regaining compliance with the continued listing requirements and maintaining the listing of our common stock on the Nasdaq Capital Market. On December 7, 2023, we received a notice from Nasdaq (the “Notice”) informing us that because the closing bid price for our common stock was below $1.00 for 30 consecutive trading days, we were not in compliance with the minimum bid price requirement for continued listing on Nasdaq, as set forth in Nasdaq Marketplace Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

In accordance with Nasdaq Marketplace Rule 5810(c)(3)(A), we were granted a period of 180 calendar days from December 7, 2023, or until June 4, 2024, to regain compliance with the Minimum Bid Price Requirement. Subsequently, on May 23, 2024, we received a letter from the Listing Qualifications Staff (the “Staff”) informing the Company that it was not in compliance with the minimum stockholders’ equity requirement for continued listing on Nasdaq, under Listing Rule 5550(b)(1) (the “Stockholder’s Equity Requirement”), because the Company’s stockholders’ equity of $885,000, as reported in the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2024, was below the required minimum of $2.5 million, and because, as of May 23, 2024, the Company did not meet the alternative compliance standards, relating to the market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years.

As a result, on June 5, 2024, we received a letter from Nasdaq indicating the Company’s continued non-compliance with Nasdaq Marketplace Rule 5550(a)(2) (the “Letter”). The Letter further informed the Company that the common stock would be delisted from Nasdaq unless the Company appeals the Staff's delisting determination by requesting a hearing before the Nasdaq Hearings Panel (the “Panel”). The Company's requested a hearing to request additional time to meeting the Stockholder Equity Requirement which stayed any further delisting action by the Staff pending the ultimate outcome of the hearing. The common stock remained listed and eligible for trading on Nasdaq at least pending the ultimate conclusion of the hearing process.

On June  27, 2024, we effected a 1-for-35 reverse stock split of our outstanding common stock. Additionally, in 2020, the SEC approved a Nasdaq rule change to expedite delisting of securities of companies

that have had one or more reverse stock splits with a cumulative ratio of one for 250 or more shares over the prior two-year period. Under the new rules, if a company falls out of compliance with the $1.00 minimum bid price after completing reverse stock splits over the immediately preceding two years that cumulatively result in a ratio one for 250 shares, the company will not be able to avail itself of any compliance periods and Nasdaq will instead require the issuance of a Staff delisting determination, which is appealable to a hearings panel. Our ability to remain listed on Nasdaq may be negatively impacted by this Nasdaq rule.

On July 18, 2024, the Company received a letter from the Staff informing the Company that it had regained compliance with the Minimum Bid Price Requirement, but that because it was still non-compliant with the Stockholder’s Equity Requirement the hearing would continue as scheduled as to the matter of the Stockholder’s Equity Requirement.

On July 23, 2024, the Company addressed the Panel and presented its plan of compliance for the Stockholder’s Equity Requirement to the Panel and on August 8, 2024, the Company was notified by Nasdaq that the Panel had granted the Company’s request for continued listing, subject to, among other things, the Company’s filing of its Quarterly Report on Form 10-Q for the period ending September 30, 2024, evidencing compliance with the Stockholder’s Equity Requirement. Although the Company is diligently working to do so, there can be no assurance that the Company will be able to evidence compliance with all applicable listing criteria within the period of time granted by the Panel.

If our common stock is delisted from Nasdaq, our ability to raise capital through public offerings of our securities and to finance our operations could be adversely affected. We also believe that delisting would likely result in decreased liquidity and/or increased volatility in our common stock and could harm our business and future prospects. In addition, we believe that, if our common stock is delisted, our stockholders would likely find it more difficult to obtain accurate quotations as to the price of the common stock and it may be more difficult for stockholders to buy or sell our common stock at competitive market prices, or at all.

If our common stock is delisted, our common stock would likely then trade only in the over-the-counter market. If our common stock were to trade on the over-the-counter market, selling our common stock could be more difficult because smaller quantities of shares would likely be bought and sold, transactions could be delayed, and we could face significant material adverse consequences, including: a limited availability of market quotations for our securities; reduced liquidity with respect to our securities; a determination that our shares are a “penny stock,” which will require brokers trading in our securities to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our securities; a reduced amount of news and analyst coverage for us; and a decreased ability to issue additional securities or obtain additional financing in the future. These factors could result in lower prices and larger spreads in the bid and ask prices for our common stock and would substantially impair our ability to raise additional funds and could result in a loss of institutional investor interest and fewer development opportunities for us.

In addition to the foregoing, if our common stock is delisted from Nasdaq and it trades on the over-the-counter market, the application of the “penny stock” rules could adversely affect the market price of our common stock and increase the transaction costs to sell those shares. The SEC has adopted regulations which generally define a “penny stock” as an equity security that has a market price of less than $5.00 per share, subject to specific exemptions. If our common stock is delisted from Nasdaq and it trades on the over-the-counter market at a price of less than $5.00 per share, our common stock would be considered a penny stock. The SEC’s penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer must also provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and the salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. In addition, the penny stock rules generally require that before a transaction in a penny stock occurs, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s agreement to the transaction. If applicable in the future, these rules may restrict the ability of brokers-dealers to sell our common stock and may affect the ability of investors to sell their shares, until our common stock no longer is considered a penny stock.

We continue to actively monitor our performance with respect to the listing standards and will consider available options to resolve any deficiency and maintain compliance with the Nasdaq rules. There can be no assurance that we will be able to maintain compliance or, if we fall out of compliance, regain compliance with any deficiency, or if we implement an option that regains our compliance, maintain compliance thereafter.

This prospectus, and the documents that we have filed with the SEC that are incorporated by reference, contain “forward-looking statements” within the meaning of the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Any statements about our expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and may be forward-looking uncertainties. In some cases, you can identify forward-looking statements by the use of words or phrases such as “anticipates,” “could,” “would,” “should,” “will,” “would,” “may,” “might,” “potential,” “contemplates,” “estimates,” “plans,” “seeks,” “projects,” “predicts,” “targets,” “objectives,” “continuing,” “ongoing,” “expects,” “management believes,” “we believe,” “we intend,” or the negative of these terms, or other comparable terminology intended to identify statements about the future. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus, and in particular those factors included in the sections entitled “Risk Factors” in this prospectus and in our most recent Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q filed for the periods ended March 31, 2024 and June 30, 2024, and other filings we make with the SEC from time to time, which are on file with the SEC and incorporated herein by reference.

Forward-looking statements are based on management’s current expectations, estimates, forecasts and projections about our business and the industry in which we operate, and management’s beliefs and assumptions are not guarantees of future performance or development and involve known and unknown risks, uncertainties and other factors that are in some cases beyond our control. You should refer to the “Risk Factors” sections of our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q filed for the periods ended March 31, 2024 and June 30, 2024, and other filings we make with the SEC from time to time for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this prospectus will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all.

Forward-looking statements are subject to a number of risks and uncertainties that could cause actual events to adversely differ from the expectations indicated in these forward-looking statements, including without limitation, the risks and uncertainties described in this prospectus. Actual results could differ materially from those contained in forward-looking statements. Many factors could cause actual results to differ materially from those in forward-looking statements, including those matters discussed below, as well as those listed in the “Risk Factors” section contained herein, in any prospectus supplement and any related free writing prospectus, and under similar headings in the other documents that are incorporated by reference into this prospectus.

We operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for us to predict all risk factors and uncertainties. We may not actually achieve the plans, projections or expectations disclosed in forward-looking statements, and actual results, developments or events could differ materially from those disclosed in the forward-looking statements. Forward-looking statements are subject to a number of risks and uncertainties, including without limitation, the possibility that regulatory authorities do not accept our application or approve the marketing of our products, the possibility we may be unable to raise the funds necessary for the development and commercialization of our products, and those described in our filings with the SEC.

These risks include, among other things, that:

These risks are not exhaustive. Other sections of this prospectus and the documents incorporated herein or therein may include additional factors that could harm our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment.

You should read this prospectus and the documents that we reference in this prospectus and have filed as exhibits to the Registration Statement of which this prospectus is a part with the understanding that our actual future results, levels of activity, performance and achievements may be different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

We are not selling any shares of common stock under this prospectus and we will not receive any proceeds from the sale of the shares of common stock by the Selling Securityholders. All net proceeds from the sale of the shares of common stock covered by this prospectus will go to the Selling Securityholders. We expect that the Selling Securityholders will sell their shares of common stock as described under “Plan of Distribution” beginning on page 15 of this prospectus.

We may receive proceeds from the exercise of any July Warrants and August Warrants to the extent that the July Warrants and August Warrants are exercised for cash by the Selling Securityholders. If all of the July Warrants and August Warrants were exercised for cash in full, the gross proceeds would be approximately $4.6 million. We expect to use the net proceeds from the exercise of any July Warrants and August Warrants for working capital and general corporate purposes. We can make no assurances that any of the July Warrants and August Warrants will be exercised, or if exercised, that they will be exercised for cash, the quantity which will be exercised or in the period in which they will be exercised.

The shares of common stock being offered by the Selling Securityholders are those issuable to the Selling Securityholders, upon exercise of the July Warrants and August Warrants.

We are registering the shares of common stock in order to permit the Selling Securityholders to offer the shares for resale from time to time. The Selling Securityholders may sell all, some or none of their shares of common stock in this offering. For additional information, see the section titled “Plan of Distribution” beginning on page 15 of this prospectus.

The table below lists the Selling Securityholders and other information regarding the beneficial ownership of the shares of common stock by each of the Selling Securityholders as of August 26, 2024. The number of shares of our common stock outstanding as of August 26, 2024 was 1,866,890. The second column lists the number of shares of common stock beneficially owned by each Selling Securityholder prior to the offering, based on its respective ownership of the shares of common stock and securities convertible into shares of common stock within 60 days of August 26, 2024. The third column lists the shares of common stock being offered by this prospectus by the Selling Securityholders. The fourth and fifth columns list the number of shares of common stock owned after the offering and the percentage of common stock owned after the offering, assuming in both cases, the exercise of all 469,340 July Warrants and all 483,351 August Warrants on that date, without regard to any limitations on the exercise of the July Warrants and August Warrants and the sale of all of the shares of common stock offered by that Selling Securityholder pursuant to this prospectus. Except as otherwise indicated below, based on the information provided to us by the Selling Securityholders, and to the best of our knowledge, no Selling Securityholder is a broker-dealer or an affiliate of a broker-dealer.

Below is a description of material relationships in the past three years between the Company, its predecessors or affiliates and the Selling Securityholders.

On July 24, 2024, we entered into a placement agency agreement with the July Placement Agent and the July Purchase Agreement with certain purchasers pursuant to which the Company agreed to sell, in a registered direct offering (the “July Registered Offering”), an aggregate of 469,340 shares (the “July Shares”) of the Company’s common stock at a purchase price of $4.24 per Share.

The July Shares were sold pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-280647), including a base prospectus contained therein, which was originally filed with the SEC on July 1, 2024, and was declared effective by the SEC on July 9, 2024, and a related prospectus supplement, dated July 24, 2024, related to the July Registered Offering.

Pursuant to the July Purchase Agreement, in a concurrent private placement (the “July Private Placement” and together with the July Registered Offering, the “July 2024 Offering”), the Company also agreed to sell and issue to the Selling Securityholders the July Warrants to purchase up to 938,680 shares of common stock. The July Warrants have an exercise price of $3.99 per share, were immediately exercisable and expire five years from the date of issuance.

The July Warrants were issued to the Selling Securityholders, which are institutional accredited investors, in a private placement pursuant to Section 4(a)(2) and Regulation D promulgated under the Securities Act.

Pursuant to the terms of the July Purchase Agreement, among other things, the Company is required to prepare and file with the SEC a registration statement to register for resale the shares of common stock issuable upon exercise of the July Warrants. The Company is required to use commercially reasonable efforts to have such registration statement declared effective as promptly as possible thereafter, and in any event no later than 60 days following July 25, 2024, or 90 days in the event of a review by the SEC.

Roth Capital Partners, LLC acted as the exclusive placement agent in connection with the July 2024 Offering, and as compensation in connection with the July 2024 Offering, we agreed to pay the July Placement Agent a cash fee equal to 7.0% of the gross proceeds of the July 2024 Offering and $100,000 for its expenses in connection with such offering.

Pursuant to the July Purchase Agreement in the July 2024 Offering, the Selling Securityholders were granted a right of participation for a period of 12 months following the closing of the July 2024 Offering in any issuance by the Company of common stock or common stock equivalents for cash consideration, indebtedness or a combination of units thereof, of up to an amount equal to 40% of the subsequent financing on the same terms, conditions and price provided for in the subsequent financing.

On August 23, 2024, we entered into a placement agency agreement with the August Placement Agent and the August Purchase Agreement with certain purchasers pursuant to which the Company agreed to sell, in a registered direct offering (the “August Registered Offering”), an aggregate of 483,351 shares (the “August Shares”) of the Company’s common stock at a purchase price of $1.8450 per August Share.

The August Shares were sold pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-280647), including a base prospectus contained therein, which was originally filed with the SEC on July 1, 2024, and was declared effective by the SEC on July 9, 2024, and a related prospectus supplement, dated August 23, 2024, related to the August Registered Offering.

Pursuant to the August Purchase Agreement, in a concurrent private placement (the “August Private Placement” and together with the August Registered Offering, the “August 2024 Offering”), the Company also agreed to sell and issue to the Selling Securityholders the August Warrants to purchase up to 483,351 shares of common stock. The August Warrants have an exercise price of $1.72 per share, were immediately exercisable and expire five years following the date of effectiveness of the registration statement for the purposes of registering the shares of common stock underlying the August Warrants.

The August Warrants were issued to the Selling Securityholders, which are institutional accredited investors, in a private placement pursuant to Section 4(a)(2) and Regulation D promulgated under the Securities Act.

Pursuant to the terms of the August Purchase Agreement, among other things, the Company is required to prepare and file with the SEC a registration statement to register for resale the shares of common stock issuable upon exercise of the August Warrants. The Company is required to use commercially reasonable efforts to have such registration statement declared effective as promptly as possible thereafter, and in any event no later than 60 days following August 26, 2024, or 90 days in the event of a review by the SEC.

Ladenburg Thalmann & Co. Inc. acted as the exclusive placement agent in connection with the August 2024 Offering, and as compensation in connection with the August 2024 Offering, we agreed to (i) pay the August Placement Agent a cash fee equal to 8.0% of the gross proceeds of the August 2024 Offering, (ii) pay the August Placement Agent up to $90,000 for its expenses in connection with such offering, and (iii) issue warrants to purchase up to 14,501 shares of common stock (“Placement Agent Warrants”). The Placement Agent Warrants have substantially the same terms as the August Warrants described above, except that the Placement Agent Warrants have an exercise price of $3.04425 per share and expire five (5) years following the commencement of the sales pursuant to this offering.

The following table sets forth certain information with respect to the beneficial ownership of our Common Stock as of August 26, 2024 by:

The percentage beneficial ownership information shown in the table is based on an aggregate of 1,866,890 shares of our Common Stock outstanding as of August 26, 2024, assuming no exercise of outstanding options issued under our equity incentive plans and no exercise of warrants, including the July Warrants.

We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of Common Stock issuable pursuant to: (i) the exercise of stock options that are either immediately exercisable or exercisable on or before October 25, 2024, which is 60 days after August 26, 2024; (ii) the vesting of restricted stock units on or before October 25, 2024, which is 60 days after August 26, 2024; and (iii) outstanding warrants to purchase common stock held by that person that is either immediately exercisable or exercisable on or before October 25, 2024, which is 60 days after August 26, 2024. These shares are deemed to be outstanding and beneficially owned by the person holding those options, restricted stock units and warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each of the individuals and entities named in the table below is c/o Nuwellis, Inc., 12988 Valley View Road, Eden Prairie, MN 55344.

Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Each Selling Securityholder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock covered hereby on the principal trading market or any other stock exchange, market or trading facility on which the shares of common stock are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Securityholder may use any one or more of the following methods when selling shares of our common stock:

The Selling Securityholders may also sell shares of common stock under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Securityholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Securityholders (or, if any broker-dealer acts as agent for the purchaser of shares of our common stock, 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 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 shares of common stock or interests therein, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of common stock in the course of hedging the positions they assume. The Selling Securityholders may also sell shares of common stock short and deliver these shares of common stock to close out their short positions, or loan or pledge the shares of common stock to broker-dealers that in turn may sell these shares of common stock. The Selling Securityholders 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 the shares of common stock offered by this prospectus, which shares of common stock such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Securityholders and any broker-dealers or agents that are involved in selling the shares of common stock 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 shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Securityholder 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 shares of common stock.

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

The resale shares of common stock 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 of the shares of common stock 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 shares of common stock may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Securityholders 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 common stock by the Selling Securityholders or any other person. We will make copies of this prospectus available to the Selling Securityholders 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).

The following summary descriptions of our common stock, preferred stock and common warrants are based on the provisions of our certificate of incorporation and bylaws, and the applicable provisions of the Delaware General Corporation Law. This information may not be complete in all respects and is qualified in its entirety by reference to the provisions of our certificate of incorporation, bylaws and the Delaware General Corporation Law. For information on how to obtain copies of our certificate of incorporation and bylaws, see the information below under the heading “Where You Can Find Additional Information.”

Our authorized capital stock consists of 100,000,000 shares of common stock, par value $0.0001 per share, and 40,000,000 shares of preferred stock, par value $0.0001 per share, 30,000 of which are designated as Series A Junior Participating Preferred Stock, 18,000 of which are designated Series F Convertible Preferred Stock (the “Series F Preferred Stock”), and 600,000 of which are designated Series J Convertible Preferred Stock (the “Series J Convertible Preferred Stock”) as of December 31, 2023. Once shares of Series F Preferred Stock and Series J Preferred Stock are converted, redeemed or reacquired by us, such shares shall resume the status of authorized but unissued shares of undesignated preferred stock.

As of August 26, 2024, we had (i) 1,866,890 outstanding shares of common stock, (ii) 127 outstanding shares of Series F Preferred Stock, which, at the currently applicable conversion price, would convert into 68,961 shares of common stock, subject to future adjustment, (iii) 88 outstanding shares of Series J Convertible Preferred Stock, which, at the currently applicable conversion price, would convert into 62 shares of common stock, subject to future adjustment, (iv) outstanding options to acquire 3,906 shares of our common stock, (v) outstanding warrants to purchase 3,711,820 shares of our common stock, and (vi) 23,762 shares of common stock underlying the outstanding Series J Convertible Preferred Stock issuable upon the exercise of 1,920 Series J warrants issued in October 2023 in a best efforts registered public offering.

The following description summarizes the most important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description you should refer to our certificate of incorporation, bylaws and certificate of designation of preferences, rights and limitations of Series F Preferred Stock and Series J Preferred Stock, copies of which have been incorporated by reference as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of the DGCL.

Holders of our common stock are entitled to receive dividends when and as declared by our board of directors out of funds legally available.

Holders of our common stock are entitled to one vote for each share on each matter properly submitted to our stockholders for their vote; provided however, that except as otherwise required by law, holders of our common stock will not be entitled to vote on any amendment to our certificate of incorporation (including any certificate of designation filed with respect to any series of preferred stock) that relates solely to the terms of a series of outstanding preferred stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon by law or pursuant to our certificate of incorporation (including any certificate of designation filed with respect to any series of preferred stock).

Subject to the voting restrictions described above, holders of our common stock may adopt, amend or repeal our bylaws and/or alter certain provisions of our certificate of incorporation with the affirmative vote of the holders of at least 66 2∕3% of the voting power of all of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class, in addition to any vote of the holders of a class or series of our stock required by law or our certificate of incorporation. Those provisions of our certificate of incorporation that may be altered only by the super-majority vote described above relate to:

Holders of our common stock do not have any conversion, redemption or preemptive rights pursuant to our organizational documents.

In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in any assets remaining after the satisfaction in full of the prior rights of creditors and the aggregate of any liquidation preference pursuant to the terms of any certificate of designations filed with respect to any series of preferred stock, including our outstanding Series F Preferred Stock and Series J Preferred Stock.

Our common stock is listed on the Nasdaq Capital Market under the symbol “NUWE.”

We may issue any class of preferred stock in any series. Our board of directors has the authority to establish and designate series, and to fix the number of shares included in each such series and to determine or alter for each such series, such voting powers, designation, preferences, and relative participating, optional, or other rights and such qualifications, limitations or restrictions thereof. Our board of directors is not restricted in repurchasing or redeeming such stock while there is any arrearage in the payment of dividends or sinking fund installments. Our board of directors is authorized to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. The number of authorized shares of preferred stock may be increased or decreased, but not below the number of shares thereof then outstanding, by the affirmative vote of the holders of a majority of the common stock, without a vote of the holders of the preferred stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any certificate of designation filed with respect to any series of preferred stock.

Prior to issuance of shares of any series of preferred stock, our board of directors is required by Delaware law to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The certificate of designation fixes for each class or series the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Any shares of preferred stock will, when issued, be fully paid and non-assessable.

As of August 26, 2024, there were warrants outstanding to purchase a total of 3,711,820 shares of our common stock, which expire between 2024 and 2029. Each of these warrants entitles the holder to purchase one share of common stock at prices ranging from $1.72 to $6,615,000 per share. Certain of these warrants have

a net exercise provision under which its holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of our common stock at the time of exercise of the warrant after deduction of the aggregate exercise price. Each of these warrants also contains provisions for the adjustment of the exercise price and the aggregate number of shares issuable upon the exercise of the warrant in the event of dividends, share splits, reorganizations and reclassifications and consolidations. Certain of these warrants provide that, subject to limited exceptions, a holder will not have the right to exercise any portion of its warrants if the holder, together with its affiliates, would beneficially own over 4.99% of our then outstanding common stock following such exercise; provided, however, that upon prior notice to us, the warrant holder may increase its ownership, provided that in no event will the ownership exceed 9.99%.

Exercisability. The July Warrants were exercisable immediately and expire five years from the initial date of issuance. The July Warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and, at any time a registration statement registering the issuance of the Common Stock underlying the July Warrants under the Securities Act is effective and available for the issuance of such shares, or an exemption from registration under the Securities Act is available for the issuance of such shares, by payment in full in immediately available funds for the number of Common Stock purchased upon such exercise. If at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Common Stock underlying the July Warrants, then the July Warrants may also be exercised, in whole or in part, at such time by means of a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of Common Stock determined according to the formula set forth in the July Warrant.

Exercise Limitation. A holder will not have the right to exercise any portion of the July Warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or 9.99% upon the request of the investor) of the number of shares of Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the July Warrants. However, any holder may increase or decrease such percentage, provided that any increase will not be effective until the 61st day after such election.

Exercise Price. The July Warrants have an exercise price of $3.99 per share. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our Common Stock and also upon any distributions of assets, including cash, stock or other property to our shareholders.

Transferability. In accordance with its terms and subject to applicable laws, a July Warrant may be transferred at the option of the holder upon surrender of the July Warrant to us together with the appropriate instruments of transfer and payment of funds sufficient to pay any transfer taxes (if applicable).

Exchange Listing. There is no established public trading market for the July Warrants being issued in the concurrent private placement, and we do not expect a market to develop. We do not intend to apply for listing of the July Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the July Warrants will be limited.

Fundamental Transactions. In the event of any fundamental transaction, as described in the July Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our Common Stock, then upon any subsequent exercise of a July Warrant, the holder will have the right to receive as alternative consideration, for each share of Common Stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of Common Stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of Common Stock for which the July Warrant is exercisable immediately prior to such event. In addition, in the event of a fundamental transaction, we or any successor entity will be required to purchase at a holder’s option, exercisable at any time concurrently with or within 30 days after the consummation of the fundamental transaction (or, if later, the date of the public announcement of the applicable fundamental transaction), such holder’s July Warrants and generally including any merger with

or into another entity, sale of all or substantially all of our assets, tender for cash in an amount equal to the value of the remaining unexercised portion of such holder’s July Warrants, determined in accordance with the Black Scholes option pricing model as more particularly set forth in the July Warrants.

Rights as a Shareholder. Except as otherwise provided in the July Warrants or by virtue of such holder’s ownership of our Common Stock, the holder of a July Warrant does not have the rights or privileges of a holder of our Common Stock, including any voting rights, until the holder exercises the July Warrant.

Registration Rights. We have agreed to file a registration statement covering the resale of the shares underlying the July Warrants as soon as practicable (and in any event within 30 days of the date of the securities purchase agreement entered into between the purchasers and us). We must use commercially reasonable efforts to cause such registration statement to become effective within 60 days following the closing date of the offering (or, in the event of a review by the SEC, the 90th calendar day following the closing date of the offering) and to keep such registration statement effective at all times until the purchasers no longer own any July Warrants or shares underlying the July Warrants.

Exercisability. The August Warrants were exercisable immediately and expire five years following the date of effectiveness of the registration statement for the purposes of registering the shares of common stock underlying the August Warrants. The August Warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and, at any time a registration statement registering the issuance of the Common Stock underlying the August Warrants under the Securities Act is effective and available for the issuance of such shares, or an exemption from registration under the Securities Act is available for the issuance of such shares, by payment in full in immediately available funds for the number of Common Stock purchased upon such exercise. If at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Common Stock underlying the August Warrants, then the August Warrants may also be exercised, in whole or in part, at such time by means of a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of Common Stock determined according to the formula set forth in the August Warrant.

Exercise Limitation. A holder will not have the right to exercise any portion of the August Warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or 9.99% upon the request of the investor) of the number of shares of Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the August Warrants. However, any holder may increase or decrease such percentage, provided that any increase will not be effective until the 61st day after such election.

Exercise Price. The August Warrants have an exercise price of $1.72 per share. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our Common Stock and also upon any distributions of assets, including cash, stock or other property to our shareholders.

Transferability. In accordance with its terms and subject to applicable laws, an August Warrant may be transferred at the option of the holder upon surrender of the August Warrant to us together with the appropriate instruments of transfer and payment of funds sufficient to pay any transfer taxes (if applicable).

Exchange Listing. There is no established public trading market for the August Warrants being issued in the concurrent private placement, and we do not expect a market to develop. We do not intend to apply for listing of the August Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the August Warrants will be limited.

Fundamental Transactions. In the event of any fundamental transaction, as described in the August Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our Common Stock, then upon any subsequent exercise of an August Warrant, the holder will have the right to receive as alternative consideration, for each share of Common Stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of Common Stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of Common Stock for which the August Warrant is exercisable

immediately prior to such event. In addition, in the event of a fundamental transaction, we or any successor entity will be required to purchase at a holder’s option, exercisable at any time concurrently with or within 30 days after the consummation of the fundamental transaction (or, if later, the date of the public announcement of the applicable fundamental transaction), such holder’s August Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender for cash in an amount equal to the value of the remaining unexercised portion of such holder’s August Warrants, determined in accordance with the Black Scholes option pricing model as more particularly set forth in the August Warrants.

Rights as a Shareholder. Except as otherwise provided in the August Warrants or by virtue of such holder’s ownership of our Common Stock, the holder of an August Warrant does not have the rights or privileges of a holder of our Common Stock, including any voting rights, until the holder exercises the August Warrant.

Registration Rights. We have agreed to file a registration statement covering the resale of the shares underlying the August Warrants as soon as practicable (and in any event within 30 days of the date of the securities purchase agreement entered into between the purchasers and us). We must use commercially reasonable efforts to cause such registration statement to become effective within 60 days following the closing date of the offering (or, in the event of a review by the SEC, the 90th calendar day following the closing date of the offering) and to keep such registration statement effective at all times until the purchasers no longer own any August Warrants or shares underlying the August Warrants.

Certain provisions of our certificate of incorporation and bylaws may be considered to have an anti-takeover effect, such as those provisions:

We are also subject to Section 203 of the DGCL, which generally prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

In general, Section 203 defines a “business combination” to include the following:

In general, Section 203 of the DGCL defines an interested stockholder as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by any of these entities or persons.

The above-summarized provisions of our certificate of incorporation and bylaws and the above-summarized provisions of the DGCL could make it more difficult to acquire us by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions are expected to discourage certain types of coercive takeover practices and takeover bids that our board of directors may consider inadequate and to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms.

Our Fourth Amended and Restated Certificate of Incorporation, as amended, provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a

breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL; or any action asserting a claim against us that is governed by the internal affairs doctrine. These provisions would not apply to suits brought to enforce a duty or liability created by the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. Our Fourth Amended and Restated Certificate of Incorporation, as amended, will further provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, subject to applicable law. Any person or entity purchasing or otherwise acquiring any interest in our securities shall be deemed to have notice of and consented to these provisions. Our exclusive forum provision will not relieve us of our duties to comply with the federal securities laws and the rules and regulations thereunder, and our stockholders will not be deemed to have waived our compliance with these laws, rules and regulations.

The provisions of the DGCL, our Fourth Amended and Restated Certificate of Incorporation, as amended, and our Third Amended and Restated Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our certificate of incorporation limits the liability of our directors to the fullest extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for any:

These limitations of liability do not apply to liabilities arising under federal securities laws and do not affect the availability of equitable remedies such as injunctive relief or rescission.

Our bylaws provide that we will indemnify and advance expenses to our directors and officers to the fullest extent permitted by law or, if applicable, pursuant to indemnification agreements. They further provide that we may choose to indemnify our other employees or agents from time to time. Subject to certain exceptions and procedures, our bylaws also require us to advance to any person who was or is a party, or is threatened to be made a party, to any proceeding by reason of the person’s service as one of our directors or officers all expenses incurred by the person in connection with such proceeding.

Section 145(g) of the DGCL and our bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in connection with their services to us, regardless of whether our bylaws permit indemnification. We maintain a directors’ and officers’ liability insurance policy.

We entered into indemnification agreements with each of our directors and executive officers that provide, in general, that we will indemnify them to the fullest extent permitted by law in connection with their service to us or on our behalf and, subject to certain exceptions and procedures, that we will advance to them all expenses that they incur in connection with any proceeding to which they are, or are threatened to be made, a party.

At present, there is no pending litigation or proceeding involving any of our directors or officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Pursuant to the Securities Purchase Agreement in the July 2024 Offering, the Selling Securityholders were granted a right of participation for a period of 12 months following the closing of the July 2024 Offering in any issuance by the Company of common stock or common stock equivalents for cash consideration, indebtedness or a combination of units thereof, of up to an amount equal to 40% of the subsequent financing on the same terms, conditions and price provided for in the subsequent financing.
