Overview of our Company
We are a publicly traded biotechnology company pioneering the development of targeted therapies with the potential to deliver genetic medicines to distal sites of disease. Our proprietary RedTail platform features an engineered enveloped oncolytic virus designed for systemic delivery and targeting of metastatic sites. This advanced enveloped technology is intended to shield the virus from immune clearance, allowing virotherapy to effectively reach tumor sites, induce tumor lysis, and deliver potent genetic medicine(s) to metastatic locations. We expect to enter the clinic in the first quarter of 2027 with CLD-401, the first compound from the RedTail platform, delivering IL-15 superagonist to the tumor microenvironment (“TME”).
Our RedTail platform is the culmination of over a decade of work around genetic engineering of viruses and allows for the systemic administration of a proprietarily-modified oncolytic virus that can:
| ● | Survive in circulation and home to metastatic tumor sites; | |
| ● | Only replicates in tumor cells; | |
| ● | Induce immunogenic cell death in tumor cells and immune priming in the TME; | |
| ● | Deliver genetic medicine payloads for expression in the TME like IL-15 superagonist (CLD-401), coexpression of in situ T-cell engagers (TCEs) and T-cell activators as in CLD-501 (anti-TROP2) and CLD-502 (anti-EpCAM), to combine oncolytic tumor killing, TME remodeling, and T-cell redirection against tumor antigens; |
Our legacy SuperNova and NeuroNova stem cell based oncolytic virus platforms are designed to:
| ● | Protect oncolytic viruses from neutralizing antibodies and complement inactivation and innate immune cell inactivation; | |
| ● | Enhance oncolytic viral amplification inside the allogeneic cells; and | |
| ● | Modify the TME to allow improvements in cell targeting and viral amplification at the tumor site. |
Oncolytic viruses have been pursued as therapeutic platforms in oncology because of their ability to preferentially infect and replicate within cancer cells, resulting in both direct lysis of the tumor cells as well as activation of an antitumor immune response, while leaving normal, healthy cells unharmed. Despite the promises of oncolytic viruses, a major obstacle against their therapeutic use has been their rapid elimination by the patient’s immune system; this has meant that oncolytic viruses have been largely relegated to being used for local delivery to tumors but have not been successful in patients with extensive metastatic disease. The only approved oncolytic virus therapy is T-VEC (Imlygic®), a modified herpes simplex virus (“HSV”) for the treatment of patients with melanoma given intratumorally.
| S-2 |
We have been working on oncolytic viruses for over a decade. Our NeuroNova investigational drug candidate is currently in a Phase 1 trial being run and funded by our partner, City of Hope, in an investigator-initiated trial and we have an open IND for a Phase 1 trial for our SuperNova investigational drug candidate (CLD-201). In July 2025 we were granted Fast Track Designation to CLD-201 by the U.S. Food and Drug Administration (“FDA”) for the treatment of patients with soft tissue sarcoma. The platforms used in NeuroNova and SuperNova use oncolytic viruses embedded in stem cells to facilitate initial viral amplification and expansion at the tumor sites. This approach has shown substantial benefit over unprotected virus in preclinical studies of intratumoral delivery, but stem cell encapsulation does not allow for systemic delivery of virus to tumor metastases in animal models. The size of the stem cells prohibited efficient dissemination into metastatic sites.
More recently, we used the learnings from NeuroNova and SuperNova to create RedTail, a novel oncolytic viral platform that avoids immune clearance allowing for systemic delivery. RedTail utilizes a proprietary form of enveloped virus with genetic modifications, including engineered expression of CD55 on the enveloped virus, to avoid immune clearance. The virus used in RedTail has been further proprietarily engineered to specifically replicate only in tumor tissue where the virus also has the ability to deliver genetic medicines to the tumor microenvironment. Because the virus is not encapsulated in stem cells, it is thousands of times smaller than the NeuroNova or SuperNova products and disseminates efficiently into metastatic sites in syngeneic animal models. In addition, the virus can be engineered to express genetic medicines while replicating in the tumor.
CLD-401, the first lead derived from the RedTail platform. CLD-401 is enveloped and overexpressed CD55 on its outer membrane. It is tropic for tumor cells and, when replicating, expresses IL-15 superagonist at high concentrations in the tumor microenvironment. In animal models, CLD-401 can be given systemically and clear metastatic sites in syngeneic tumor mouse models with demonstrated enhanced biological efficacy. The combination of the RedTail virus with its genetic payload drives complete tumor eradication in the tumor models compared to the RedTail virus alone. We believe that RedTail, given its systemic administration and targeting to metastatic sites and its delivery of genetic medicines, represents a major advancement in the space of oncolytic virus in oncology. We are developing additional leads from the RedTail platform including CLD-501 (anti-TROP2) and CLD-502 (anti-EpCAM), which co-express an in situ TCE and an IL-15 superagonist.
Since inception, our operations have focused on organizing and staffing our company, business planning, raising capital, acquiring and developing our technology, establishing our intellectual property portfolio, identifying potential product candidates and undertaking preclinical studies and manufacturing. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations primarily through private sales of common stock, warrants, convertible promissory notes, term debt, and the issuance of publicly traded securities. These investments have included and have been made by various related parties, including our former chief executive officer and former chairman of the Board of Directors.
Since inception, we have incurred significant operating losses. Our net loss was $8.3 million for the six-month period ended June 30, 2026. As of June 30, 2026, we had an accumulated deficit of $149.9 million. We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, as we advance our current and future product candidates through preclinical and clinical development, manufacture drug product and drug supply, seek regulatory approval for our current and future product candidates, maintain and expand our intellectual property portfolio, hire additional research and development and business personnel and operate as a public company.
| S-3 |
Changes in economic conditions, including rising interest rates, public health issues, lower consumer confidence, volatile equity capital markets, tariffs, ongoing supply chain disruptions, and the impacts of geopolitical conflicts, may also affect our business.
We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. In addition, if we obtain regulatory approval for our product candidates and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, manufacturing and distribution activities.
As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings and debt financings or other sources, such as potential collaboration agreements, strategic alliances, and licensing arrangements. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our inability to raise capital or enter into such agreements as, and when needed, could have a material adverse effect on our business, results of operations and financial condition.
Based on our operating plan, we believe we do not have sufficient cash on hand to support current operations for at least one year from the date of issuance of our unaudited condensed consolidated financial statements as of and for the three and six months ended June 30, 2026. We have concluded that this circumstance raises substantial doubt about our ability to continue as a going concern. See Note 1 to our unaudited condensed consolidated financial statements. In addition, we will be required to raise additional capital through the issuance of our equity securities to support our operations which will have an ownership and economic dilutive effect to our current shareholders who purchased their shares of common stock at prices above our current trading price, and such capital raising may adversely affect the price of our common stock. Further, the sale of or the perception of a sale of a substantial number of our common stock by certain selling securityholders pursuant to another registration statement filed with the SEC will adversely affect the price of our common stock due to our limited trading volume, adversely affect the share price that we may obtain in future financings, and may adversely affect our ability to conduct and complete future financings.
Recent Developments
Reverse Stock Split
On August 4, 2025, our stockholders approved an amendment to our Second Amended and Restated Certificate of Incorporation, as amended, to effect a reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.0001 per share (“Common Stock”), at a ratio of 1-for-12 (the “Reverse Stock Split”). The Reverse Stock Split became effective on August 4, 2025 (the “Effective Date”). The Common Stock began trading on a split-adjusted basis at the commencement of trading on August 5, 2025, under the Company’s existing trading symbol “CLDI.”
On June 12, 2026, our stockholders approved an amendment to our Second Amended and Restated Certificate of Incorporation, as amended, to, at the discretion of the Board of Directors, effect a reverse stock split with respect to our shares of issued and outstanding Common Stock, which consists of Voting Common Stock and Non-Voting Common Stock, at a ratio between 1-for-2 and 1-for-16 (the “Range”), with the ratio within such Range to be determined at the discretion of the Board. On July 30, 2026, we effected the reverse stock split of our outstanding shares of common stock at a ratio of 1-for-16 (“July 2026 Reverse Split”). Our common stock commenced trading on a split-adjusted basis on July 31, 2026 under the existing symbol of “CLDI”.
Except as otherwise indicated, all references to the Company’s Common Stock, share data, per share data and related information in this prospectus supplement have been adjusted for the Reverse Stock Split and the July 2026 Reverse Split, as applicable, as if they had occurred at the beginning of the earliest period presented.

Financing Matters
On May 6, 2026, we issued a warrant (“Warrant”) to an accredited investor to purchase up to 1,086,957 unvested shares of our common stock (“Common Stock”) with an exercise price of $3.68 in a private placement transaction. The Warrant is exercisable beginning on the date that is six months from the issue date, and is subject to certain vesting conditions as described further. The holder of the Warrant may from time to time prior to July 8, 2026, agree to acquire, and we may agree to sell to such holder, up to an aggregate of $4.0 million of Common Stock in issuances registered under the Securities Act. The Warrant will vest in proportion to issuances described in the preceding sentence that are consummated. Neither the holder of the Warrant nor we have any obligation to agree to or consummate any such issuances.
On May 28, 2026, we amended and restated the Warrant to among other things: (i) condition the exercise of the Warrant and the issuance of the Common Stock upon exercise pursuant to the terms of the Warrant, to the receipt of the approval of our stockholders; (ii) increase the Minimum Vesting Acquisition Amount, as such term is defined in the Warrant, from $500,000 to $1,000,000; and (iii) to extend the Vesting Termination Date, as such term is defined in the Warrant, from July 8, 2026 to September 30, 2026.
At the Market Offering Agreement
On October 11, 2024, the Company entered into an At The Market Offering Agreement (the “Sales Agreement”) with Ladenburg Thalmann & Co. Inc. (the “Ladenburg”), under which the Company may, from time to time, in its sole discretion, issue and sell through Ladenburg, acting as agent or principal, shares of the Company’s Common Stock. The Company will pay Ladenburg a cash commission of 3.0% of the aggregate gross sales proceeds of shares sold through Ladenburg under the Sales Agreement. The Company also agreed to reimburse Ladenburg for certain specified expenses, including the fees and disbursements of its counsel, in an amount not to exceed $50,000, in addition to certain ongoing disbursements of its legal counsel up to $7,500 in connection with diligence bring downs.
Under the terms of the Sales Agreement, the Company may also sell shares to Ladenburg as principal for its own account at prices agreed upon at the time of sale. If the Company sells shares to Ladenburg as principal, it will enter into a separate terms agreement with Ladenburg in substantially the form attached to the Sales Agreement.
The Company is not obligated to sell any shares under the Sales Agreement. The offering of the shares pursuant to the Sales Agreement may be terminated by either the Company or Ladenburg, as permitted therein. Since our entry into the Sales Agreement and as of the date of this Prospectus Supplement, we have offered and sold 1,439,721 shares of common stock for gross proceeds of $9.9 million pursuant to the Sales Agreement (as adjusted for the July 2026 Reverse Split).
New Facility Lease
On July 10, 2026, we entered into a new lease agreement (the “New Lease”) for approximately 9,038 rentable square feet of office and laboratory space located at 5580 Morehouse Drive, Suite 120, San Diego, California, with an initial term of 44 months commencing October 1, 2026, and expiring May 31, 2030, with one option to extend for an additional three years at the then-prevailing fair market rate. We will be required to make monthly base rental payments of approximately $52,000 per month for the first 12 months, with an annual 3% increase in such amount on each anniversary of the commencement date. We will also pay our share of operating expenses, property taxes and insurance, as well as a 3% management fee. We are required to deliver an irrevocable letter of credit of approximately $0.1 million within 10 calendar days of execution of the new lease.
| S-5 |
Concurrently, we also entered into a Lease Termination Agreement with respect to our existing lease at 4475 Executive Drive, San Diego, California, which will terminate effective September 30, 2026 (the “Termination Date”), with no early termination fee payable. The Termination Agreement also reduces the remaining base rent payments due under the existing lease from June 1, 2026 through the Termination Date from approximately $118,000 per month to approximately $26,000 per month, and it also reduces the monthly estimated payment for Expenses, Taxes and insurance to a flat monthly fee of approximately $10,000 per month.
In connection with the Lease Termination Agreement, Mr. Camaisa entered into a Guarantee Termination Agreement to be effective on the Termination Date, pursuant to which, the Guarantee under the existing lease shall terminate and be of no further force or effect.

An investment in our Common Stock involves a high degree of risk. 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 most recent Annual Report on Form 10-K, as may be updated in our subsequent Quarterly Reports on Form 10-Q, and other reports and documents that are incorporated by reference into this prospectus supplement and the accompanying base prospectus, before deciding whether to purchase any of our Common Stock in this offering. . The market or trading price of our Common Stock could decline due to any of these risks. In addition, please read “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. If any of the risks or uncertainties described in our SEC filings or any additional risks and uncertainties actually occur, our business, financial condition, results of operations and cash flow could be materially and adversely affected. In that case, the market value and/or trading price, as applicable, of our securities could decline, and you might lose all or part of your investment.
Our management will have broad discretion over the use of the net proceeds from this offering, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.
Our management will have broad discretion in the application of the net proceeds from this offering, and our stockholders will not have the opportunity as part of their investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. The failure by our management to apply these funds effectively could harm our business. See “Use of Proceeds” on page S-9 of this prospectus supplement for a description of our proposed use of proceeds from this offering.
Our independent registered public accounting firm has included an explanatory paragraph relating to our ability to continue as a going concern in its report on our audited financial statements included in our Annual Report on Form 10-K for the Fiscal year ended December 31, 2025.
The report from our independent registered public accounting firm for the year ended December 31, 2025, includes an explanatory paragraph stating that we have significant working capital deficiency, and have incurred significant losses and need to raise additional funds to meet our obligations and sustain our operations. These conditions raise substantial doubt about our ability to continue as a going concern. As of June 30, 2026, we had approximately $4.1 million in cash and restricted cash of $0.2 million, an accumulated deficit of approximately $149.9 million and working capital of approximately $2.2 million. We believe that our existing cash and cash equivalents as of June 30, 2026, and our anticipated expenditures and commitments for the next twelve months, will not enable us to fund our operating expenses and capital expenditure requirements for the twelve months from June 30, 2026. Our recurring losses from operations since inception and required additional funding to finance our operations raise substantial doubt about our ability to continue as a going concern. These conditions could materially limit our ability to raise additional funds through the issuance of new debt or equity securities or otherwise. There is no assurance that sufficient financing will be available when needed, or at all, to allow us to continue as a going concern. The perception that we may not be able to continue as a going concern may also make it more difficult to operate our business due to concerns about our ability to meet our contractual obligations. Our ability to continue as a going concern is contingent upon, among other factors, the sale of our securities. There is no assurance that sufficient financing will be available when needed, or at all, to allow us to continue as a going concern.
If we are unable to secure additional capital, we may be required to curtail our clinical and research and development initiatives and take additional measures to reduce costs in order to conserve our cash in amounts sufficient to sustain operations and meet our obligations. These measures could cause significant delays in our clinical and regulatory efforts, which is critical to the realization of our business plan. The consolidated financial statements do not include any adjustments that may be necessary should we be unable to continue as a going concern. It is not possible for us to predict at this time the potential success of our business. The revenue and income potential of our proposed business and operations are currently unknown. If we cannot continue as a viable entity, you may lose some or all of your investment.
Sales of a significant number of shares of our Common Stock in the public markets or significant short sales of our Common Stock, or the perception that such sales could occur, could depress the market price of our Common Stock and impair our ability to raise capital.
Sales of a substantial number of shares of our Common Stock or other equity-related securities in the public markets, could depress the market price of our Common Stock. This offering may contribute to a depressed market price of our Common Stock. If there are significant short sales of our Common Stock, the price decline that could result from this activity may cause the share price to decline more so, which, in turn, may cause long holders of the Common Stock to sell their shares, thereby contributing to sales of Common Stock in the market. Such sales also may impair our ability to raise capital through the sale of additional equity securities in the future at a time and price that our management deems acceptable, if at all.
There is a limited trading market for our Common Stock, which could make it difficult to liquidate an investment in our Common Stock, in a timely manner.
Our Common Stock is currently traded on the NYSE American. Because there is a limited public market for our Common Stock, investors may not be able to liquidate their investment whenever desired. We cannot assure that there will be an active trading market for our Common Stock and the lack of an active public trading market could mean that investors may be exposed to increased risk. In addition, if we failed to meet the criteria set forth in SEC regulations, various requirements would be imposed by law on broker-dealers who sell our securities to persons other than established customers and accredited investors. Consequently, such regulations may deter broker-dealers from recommending or selling our Common Stock, which may further affect its liquidity.
You may experience future dilution as a result of future equity offerings.
In order to raise additional capital, we may in the future offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price per share paid by any investor in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by any investor in this offering, and investors purchasing shares or other securities in the future could have rights superior to you. The price per share at which we sell additional shares of our Common Stock, or securities convertible or exchangeable into shares of Common Stock, in future transactions may be higher or lower than the price per share paid by any investor in this offering.
We do not intend to pay dividends on our Common Stock in the foreseeable future.
We have never paid cash dividends on our Common Stock. We currently intend to invest our future earnings, if any, to fund our growth and not to pay any cash dividends on our Common Stock. Because we do not intend to pay dividends, your ability to receive a return on your investment will depend on any future appreciation in the market price of our Common Stock. We cannot be certain that our Common Stock will appreciate in price.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus supplement, the accompanying base prospectus, the documents that we incorporate by reference herein or therein and any free writing prospectuses that we may authorize for use in connection with this offering contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. These forward-looking statements can generally be identified as such because the context of the statement will include words such as “may,” “will,” “intend,” “plan,” “believe,” “anticipate,” “expect,” “estimate,” “predict,” “potential,” “continue,” “likely,” or “opportunity,” the negative of these words or words of similar import. Similarly, statements that describe our future plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. Discussions containing these forward-looking statements may be found, among other places, in the “Business” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections incorporated by reference from our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q for the quarterly periods ended subsequent to our filing of such Annual Report on Form 10-K, as well as any amendments thereto reflected in subsequent filings with the SEC.
These forward-looking statements are based largely on our expectations and projections about future events and future trends affecting our business and are subject to risks and uncertainties that could cause actual results to differ materially from those anticipated in the forward-looking statements. The risks and uncertainties include, among others, those noted in “Risk Factors” above and in any applicable prospectus supplement or free writing prospectus, and those included in the documents that we incorporate by reference herein and therein.
In addition, past financial and/or operating performance is not necessarily a reliable indicator of future performance, and you should not use our historical performance to anticipate results or future period trends. We can give no assurances that any of the events anticipated by the forward-looking statements will occur or, if any of them do, what impact they will have on our results of operations and financial condition. Except as required by law, we undertake no obligation to publicly revise our forward-looking statements to reflect events or circumstances that arise after the filing of this prospectus supplement or any supplement or free writing prospectus, or documents incorporated by reference herein and therein, that include forward-looking statements.
We estimate that our net proceeds from this Offering will be approximately $1.1 million, after deducting estimated offering expenses payable by us. We will not pay any placement agent fees, underwriting discounts or commissions in connection with this Offering.
Currently, we intend to use the net proceeds from this offering for working capital and for general corporate purposes. This represents our best estimate of the manner in which we will use the net proceeds we receive from this offering based upon the current status of our business, but we have not reserved or allocated amounts for specific purposes and we cannot specify with certainty how or when we will use any of the net proceeds. Amounts and timing of our actual expenditures will depend on numerous factors. We will retain broad discretion in the allocation and use of the net proceeds from this offering, and investors will be relying on the judgment of our management regarding the application of the proceeds of this offering.
We believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will meet our capital needs for the next two months under our current business plan.
Pending application of the net proceeds as described above, we intend to invest the proceeds to us in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, or direct or guaranteed obligations of the U.S. government, or hold as cash. We cannot predict whether the proceeds invested will yield a favorable, or any, return.
| S-9 |
We have never declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our Common Stock for the foreseeable future. We expect to retain future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends on our Common Stock will be at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and any contractual restrictions.

This summary highlights certain information about us and selected information contained in the prospectus. This summary is not complete and does not contain all of the information that may be important to you. For a more complete understanding of the Company, we encourage you to read and consider the more detailed information included or incorporated by reference in this prospectus and our most recent consolidated financial statements and related notes.
Company Overview
We are a clinical-stage immuno-oncology company that is developing innovative stem cell-based and enveloped platforms for the delivery and potentiation of oncolytic virotherapies to treat cancer. Our pipeline includes off-the-shelf product candidates designed to protect oncolytic viruses from being quickly inactivated by the patient’s immune system and target tumor sites. Once approved by the FDA, this improved delivery, both localized and systemic, and increased potency will enable us to develop treatments that target various types of cancer at different stages of progression. Our goal is to create therapies that work on any tumor, regardless of its genetic profile (universal treatments). In addition to direct targeting and killing cancer cells, our oncolytic virotherapies have shown signs of changing the tumor immune environment to induce strong anti-tumor immunity that could lead to better cancer treatment and prevent tumor recurrence.
CLD-101 (NeuroNova™ Platform) for Newly Diagnosed High Grade Glioma (“HGG”) (also referred to as “NNV1” as to the indication). CLD-101 is our product candidate utilizing our NeuroNova™ Platform targeting HGG. Prior to our licensing agreement with Northwestern University, an open-label, investigator sponsored, Phase 1, dose- escalation clinical trial for NNV1 in patients with newly diagnosed high-grade gliomas was completed. This clinical trial demonstrated that single administration of CLD-101 was well tolerated in patients with newly diagnosed HGG. A Phase 1b clinical trial will commence for NNV1 in collaboration with Northwestern University during the first quarter of 2025. This trial will explore the final dosing regimen for NNV1, including the feasibility of repeated dosing in newly diagnosed HGG. Extensive biomarker analysis will be performed on tumor biopsies and blood samples to determine viral distribution, specific tumor targeting and induction of anti-tumor immunity.
CLD-101 for Recurrent HGG (also referred to as “NNV2” as to the recurrent HGG indication). A phase 1 study evaluating the safety and feasibility of administering repeated doses of CLD-101 intracerebrally to patients with recurrent high-grade gliomas began treatment in May 2023. The study is being run by our partner, City of Hope, and started enrolling cohort 4 in January 2024. Clinical data from patients with recurrent HGG treated with repeated doses of CLD-101 is planned to support the start of a trial of repeated doses in newly diagnosed HGG.
CLD-201 (SuperNova™) for Advanced Solid Tumors (triple-negative breast cancer (“TNBC”), head & neck squamous cell carcinoma (HNSCC), and advanced soft tissue sarcoma (also referred to as “SNV1”). SNV1 is our first internally developed pre-clinical product candidate utilizing our SuperNova™ Delivery Platform. Based on our pre-clinical studies, we believe SNV1 has therapeutic potential for the treatment of multiple solid tumors such as head and neck cancer, triple-negative breast cancer and melanoma. We have held a pre-IND meeting with FDA to discuss the filing of our IND application for the clinical development of CLD-201. We anticipate commencing a Phase 1 clinical trial for SNV1 during the first half of 2025.
CLD-301 (AAA) for Multiple Indications. We are also currently engaged in early discovery research involving Adult Allogeneic Adipose-derived (“AAA”) stem cells for various indications and therapies. These AAA stem cells are theoretically multipotent, differentiating along the adipocyte, chondrocyte, myocyte, neuronal, and osteoblast lineages, and may have the ability to serve in other capacities, such as providing hematopoietic support and gene transfer with potential applications for repair and regeneration of acute and chronically damaged tissues. Pre-clinical studies involving toxicity and efficacy will be needed before an IND application may be filed with the FDA.
Our subsidiary Nova Cell, Inc. (“Nova Cell”) was formed to be a technology service provider that develops innovative stem cell-based products using our cellular manufacturing process. Through Nova Cell we anticipate expanding potential uses from oncology to other fields that require regenerative medical applications, such as cosmetics, orthopedics, auto-immune diseases, and various other therapies.
| 1 |
CLD-400 (RTNova) for Lung cancer and Metastatic Solid Tumors, our pre-clinical program involving enveloped oncolytic viruses (discovery phase), builds upon our experience of using cells to protect, potentiate and deliver virotherapies. CLD-400 program is derived from research from prior pre-clinical CLD-202 program. RTNova consists of an engineered vaccinia virus enveloped by a cell membrane, that is potentially capable of targeting lung cancer and advanced metastatic disease due to its increased ability to survive in the bloodstream. Metastatic solid tumors involve cancer cells that break away from where they first formed (primary cancer) and travel through the blood or lymph system to form new tumors, known as metastatic tumors, in other parts of the body. In preclinical studies, RTNova has shown early signs of its resistance to human humoral immunity and capability to target multiple distant and diverse tumors and transform their microenvironments leading to their elimination. In addition, the program has shown potential synergistic effects with other immunotherapies, including cell therapies, to attack and eliminate disseminated solid tumors.
Since inception, our operations have focused on organizing and staffing our company, business planning, raising capital, acquiring and developing our technology, establishing our intellectual property portfolio, identifying potential product candidates and undertaking preclinical studies and manufacturing. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations primarily through private sales of common stock, convertible preferred stock, contingently convertible and convertible promissory notes, term debt, lines of credit, Simple Agreements for Future Equity (“SAFE”) and various bank loans. These investments have included and have been made by various related parties, including our largest investor and Chief Executive Officer and Chairman of the Board of Directors.
Since inception, we have incurred significant operating losses. Our net loss was $5.8 million and $13.0 million for the three and six months ended June 30, 2024, respectively. As of June 30, 2024, we had an accumulated deficit of $112.6 million. We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, as we advance our current and future product candidates through preclinical and clinical development, manufacture drug product and drug supply, seek regulatory approval for our current and future product candidates, maintain and expand our intellectual property portfolio, hire additional research and development and business personnel and operate as a public company.
Changes in economic conditions, including rising interest rates, public health issues, including the COVID-19 pandemic and its aftereffects, lower consumer confidence, volatile equity capital markets and ongoing supply chain disruptions and the impacts of geopolitical conflicts, may also affect our business.
We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. In addition, if we obtain regulatory approval for our product candidates and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, manufacturing and distribution activities.
As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings and debt financings or other sources, such as potential collaboration agreements, strategic alliances and licensing arrangements. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our inability to raise capital or enter into such agreements as, and when needed, could have a material adverse effect on our business, results of operations and financial condition.
Based on our operating plan, we believe we do not have sufficient cash on hand to support current operations for at least one year from the date of issuance of our unaudited condensed consolidated financial statements as of, and for the three and six months ended June 30, 2024. We have concluded that this circumstance raises substantial doubt about our ability to continue as a going concern. See Note 1 to our unaudited condensed consolidated financial statements. In addition, we will be required to raise additional capital through the issuance of our equity securities to support our operations which will have an ownership and economic dilutive effect to our current shareholders who purchased their shares of common stock at prices above our current trading price, and such capital raising may adversely affect the price of our common stock. Further, the sale of or the perception of a sale of a substantial number of our common stock by certain selling securityholders pursuant to another registration statement filed with the SEC will adversely affect the price of our common stock due to our limited trading volume and adversely affect the share price that we may obtain in future financings and may adversely affect our ability to conduct and complete future financings.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company
We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act of 1933, as modified by the Jumpstart Our Business Startups Act of 2012, or the “JOBS Act.” As such, we take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including (i) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), (ii) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (iii) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. As a result, our stockholders may not have access to certain information they deem important. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year (a) following the fifth anniversary of the date of the first sale of the Company’s common stock, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which Calidi is deemed to be a large accelerated filer, which means the market value of our common stock that are held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.
In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act of 1933, as long as it is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from the sale of the securities under this prospectus for general corporate purposes, including to support research and development, including clinical trials, and general corporate purposes.
General
The following description of our capital stock, together with any additional information we include in any applicable prospectus supplement or any related free writing prospectus, summarizes the material terms and provisions of our common stock and the preferred stock that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. For the complete terms of our common stock and preferred stock, please refer to our articles of incorporation and our bylaws that are incorporated by reference into the registration statement of which this prospectus is a part. The summary below and that contained in any applicable prospectus supplement or any related free writing prospectus are qualified in their entirety by reference to our articles of incorporation and our bylaws.
Common Stock
We are authorized to issue 330,000,000 shares of common stock, $0.0001 par value per share, of which Three Hundred Twelve Million (312,000,000) are designated as Voting Common Stock (“Common Stock”) and Eighteen Million (18,000,000) are designated as Non-Voting Common Stock (the “Non-Voting Common Stock”). As of September 27, there were 10,925,712 shares of common stock issued and outstanding. The outstanding shares of common stock are validly issued, fully paid and nonassessable.
Voting Power
Holders of Common Stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. Accordingly, the holders of a plurality of votes cast can elect all of the directors standing for election, if they so choose, other than any directors that holders of any preferred stock may issue may be entitled to elect. Subject to supermajority votes for some matters, other matters shall be decided by the affirmative vote of our stockholders having a majority in voting power of the votes cast by the stockholders present or represented and voting on such matter.
The shares of Non-Voting Common Stock shall automatically convert into shares of Common Stock on a one-to-one basis at such time that such shares of Non-Voting Common Stock are released from the escrow account holding such shares in accordance with the Merger Agreement and the escrow agreement governing such escrow account.
Dividends
Subject to applicable law and the rights and preferences, if any, of any holders of any outstanding series of Preferred Stock, holders of Common Stock will be entitled to receive dividends when, as and if declared by the Board, payable either in cash, in property or in shares of capital stock.
Liquidation, Dissolution and Winding Up
Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to any holders of preferred stock having liquidation preferences, if any, the holders of Common Stock will be entitled to receive pro rata our remaining assets available for distribution.
| 4 |
Preemptive or Other Rights
Holders of Common Stock are not be entitled to preemptive rights, and the Common Stock is not subject to conversion, redemption or sinking fund provisions.
Election of Directors
The Charter and the Bylaws establish a classified board of directors that is divided into three classes with staggered three-year terms. Only the directors in one class are subject to election by a plurality of the votes cast at each annual meeting of stockholders, with the directors in the other classes continuing for the remainder of their respective three-year terms. Our Charter does not provide for cumulative voting for the election of directors.
Preferred Stock
We are authorized to issue up to 1,000,000 shares of our Preferred Stock, par value $0.0001 per share, from time to time in one or more series. As of the date of this prospectus, there were no shares of our Preferred Stock issued and outstanding.
Our Charter provides that shares of preferred stock may be issued from time to time in one or more series. The Board is authorized to establish the number of shares to be included in each such series, to fix the designation, vesting, powers (including voting powers), preferences and relative, participating, optional or other rights (and the qualifications, limitations or restrictions thereof) of the shares of each such series and to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of such series then outstanding) the number of shares of any such series, in each case without further vote or action by the stockholders. The Board is able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of Common Stock and could have anti-takeover effects. The ability of the Board to issue preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change of control of us or the removal of our existing management.

We may issue warrants for the purchase of preferred stock or common stock. Warrants may be issued independently or together with any preferred stock or common stock, and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between a warrant agent specified in the agreement and us. The warrant agent will act solely as our agent in connection with the warrants of that series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. This summary of some provisions of the securities warrants is not complete. You should refer to the securities warrant agreement, including the forms of securities warrant certificate representing the securities warrants, relating to the specific securities warrants being offered for the complete terms of the securities warrant agreement and the securities warrants. The securities warrant agreement, together with the terms of the securities warrant certificate and securities warrants, will be filed with the SEC in connection with the offering of the specific warrants.

| ● | any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants; | |
| ● | the price or prices at which and currency or currencies in which the offered securities purchasable upon exercise of the warrants may be purchased; | |

| ● | if appropriate, a discussion of Federal income tax consequences; and |
| 6 |
| ● | any other material terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants. |

Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

| ● | a description of the provisions for the payment, settlement, transfer or exchange of the units. |

Sale Through Underwriters or Dealers
Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.
If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.
If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.
Direct Sales and Sales Through Agents
We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.
We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.
Delayed Delivery Contracts
If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.
| 8 |
Continuous Offering Program
Without limiting the generality of the foregoing, we may enter into a continuous offering program equity distribution agreement with a broker-dealer, under which we may offer and sell shares of our common stock from time to time through a broker-dealer as our sales agent. If we enter into such a program, sales of the shares of common stock, if any, will be made by means of ordinary brokers’ transactions on the NYSE at market prices, block transactions and such other transactions as agreed upon by us and the broker-dealer. Under the terms of such a program, we also may sell shares of common stock to the broker-dealer, as principal for its own account at a price agreed upon at the time of sale. If we sell shares of common stock to such broker-dealer as principal, we will enter into a separate terms agreement with such broker-dealer, and we will describe this agreement in a separate prospectus supplement or pricing supplement.
Market Making, Stabilization and Other Transactions
Unless the applicable prospectus supplement states otherwise, other than our common stock all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.
Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act of 1934 (the “Exchange Act”). Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.
Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.
General Information
Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act of 1933. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.
Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell securities in a public offering with a value exceeding more than one-third of our public float in any 12-calendar month period so long as our public float remains below $75,000,000.
The validity of the issuance of the securities offered by this prospectus will be passed upon for us by Sichenzia Ross Ference Carmel LLP, New York, New York.
