<u>BUSINESS OVERVIEW</u>

**<u>OVERVIEW AND PRODUCT CANDIDATES</u>**

CEL-SCI Corporation is a late clinical-stage biotechnology company dedicated to research and development directed at improving the treatment of cancer and other diseases by using the immune system, the body's natural defense system. CEL-SCI is currently focused on the development of the following product candidates and technologies:

1) Multikine, an investigational immunotherapy under development for the potential treatment of certain head and neck cancers; and

2) L.E.A.P.S. (Ligand Epitope Antigen Presentation System) technology, or LEAPS, with several product candidates under development for the potential treatment of rheumatoid arthritis.

Multikine (Leukocyte Interleukin, Injection) is the full name of this investigational therapy, which, for simplicity, is referred to in this prospectus as Multikine. Multikine is the trademark that the Company has registered for this investigational therapy, and this proprietary name is subject to FDA review under the Company's future anticipated regulatory submission for approval. None of the Company's product candidates have been approved for sale, barter or exchange by the Food and Drug Administration (FDA) or any other regulatory agency for any use to treat disease in humans nor has the safety or efficacy of these products been established for any use. There can be no assurance that obtaining marketing approval from the FDA in the United States and by comparable agencies in most foreign countries will be granted.

**<u>MULTIKINE, THE PHASE III CLINICAL TRIAL RESULTS AND PATH FORWARD</u>**

**<u>Immunotherapy is a large, high growth market.</u>** Immunotherapies use the patient's own immune system to fight disease. These "targeted therapies" are at the forefront of modern cancer research. A Bloomberg report from January 2023 asserted that:

The global cancer immunotherapy market is expected to reach USD $196.45 billion by 2030, registering CAGR of 7.2% during the forecast period, according to a new report by Grand View Research, Inc. The rising adoption of immunotherapy over other therapy options for cancer owing to its targeted action is anticipated to increase the adoption during the forecast period. Moreover, increasing regulatory approvals from authoritarian establishments for novel immunotherapy used for oncology is also expected to further fuel the market growth.

<u>Source</u>: <u>https://www.bloomberg.com/press-releases/2023-01-18/cancer-immunotherapy-market-worth-196-45-billion-by-2030-grand-view-research-inc</u>

CEL-SCI hopes to participate in this growing market with its lead investigational therapy Multikine<sup>®</sup> (Leukocyte Interleukin, Injection). Multikine is unique among approved cancer immunotherapies because it is *<u>given first</u>*<u>, right after diagnosis, before any other treatment including surgery.</u> 

Multikine has been tested in approximately 740 patients in Phase 1, 2 and 3 clinical studies conducted in the U.S., Canada, Europe, Israel and Asia. In these studies, it has been administered in multiple doses by various routes and various frequencies to determine its safety and efficacy. The data from these studies allowed CEL-SCI to determine the patient population most responsive to Multikine and most likely to benefit from it. The target population is newly diagnosed advanced primary head and neck cancer patients with no lymph node involvement (determined via PET imaging) and with low PD-L1 tumor expression (determined via biopsy), two features that physicians routinely assess at baseline as part of standard practice.

CEL-SCI completed a bias analysis for the target population in the Phase III study in preparation for submission of data to regulatory agencies including the FDA for confirmatory registration study. The detailed data on parameters including patient age, sex, race, tumor locations, and staging demonstrate balance between the treatment and control arms. Therefore, no bias was found, which supports confidence in Multikine's efficacy results.

In the target patient population CEL-SCI believes Multikine significantly extended life. In the Phase III study, CEL-SCI observed a 73% survival rate with Multikine vs. only 45% without Multikine at 5 years after treatment, and a Hazard ratio of 0.35 (95% CIs [0.19, 0.66]).

CEL-SCI applied to the FDA for a 212-patient randomized controlled confirmatory registration study focusing only on those patients in the target population, which accounts for approximately 100,000 patients worldwide per year. In May 2024, CEL-SCI announced that the FDA indicated CEL-SCI may move forward with a confirmatory registration study of Multikine in the target population.

**<u>What is Multikine and who is it for?</u>** Multikine is a biological medicinal immunotherapy comprised of a mixture of natural cytokines and small biological molecules. Multikine is injected around the tumor and adjacent lymph nodes for three weeks as a first-line treatment *<u>before</u>* the standard of care (SOC), which is surgery followed by either radiotherapy or chemoradiotherapy. Multikine's rationale for use is to incite a locoregional immune response against the tumor before the local immune system has been compromised by the standard of care and/or disease progression.

The Multikine target population is not yet treated adult patients with resectable locally advanced primary squamous cell carcinoma of the head and neck (SCCHN) in the oral cavity and who have:

· No lymph node involvement (via PET imaging)

· Low PD-L1 tumor expression (TPS<10) (via biopsy)

PD-L1 is a protein receptor on the tumor surface that helps the tumor repel cells of the immune system. CEL-SCI believes that patients with tumors having low PD-L1 would be more likely to respond to Multikine because their tumors have lower defenses against the patient's immune system. CEL-SCI estimates that patients with tumors having low PD-L1 represent about 70% of locally advanced primary SCCHN patients.

Targeting low PD-L1 also differentiates Multikine from other immunotherapies. For example, checkpoint inhibitors like Keytruda and Opdivo appear to best serve patients having high PD-L1, because these drugs work by blocking PD1/PD-L1 receptors interaction; when this interaction (PD1/PD-L1) happens it leads to inactivation/death of the immune cells attacking the tumor. These checkpoint inhibitors appear to act best when tumors express high levels of PD-L1 receptors (usually TPS >20 to TPS >50).

Keytruda was approved by FDA in June 2025 as a perioperative (before and after surgery) treatment for resectable locally advanced head and neck cancer patients whose tumors express PD-L1 at a positive level. In Merck's Phase 3 KEYNOTE-689 trial, Keytruda reduced the risk of recurrence and progression by 30%, compared with standard of care, in patients whose tumors expressed PD-L1 (CPS ≥1). The study did not show an improvement in overall survival. Patients with low to zero levels of PD-L1 did not benefit from Keytruda.

In contrast to the results of the KEYNOTE-689, CEL-SCI's Phase 3 study showed that Multikine treated patients whose tumors expressed low (Tumor Proportion Score [TPS <10]) to zero PD-L1, had their risk of death reduced by 66% (hazard ratio 0.34, 95% CI [0.18, 0.65], p=0.0012) and extended the 5-year overall survival to 73% compared to 45% in the standard of care, log rank p=0.0015. About 70% of the patients in CEL-SCI's Phase 3 study had low to zero levels of PD-L1.

**<u>CEL-SCI believes Multikine leads to longer survival with no safety issues.</u>** Clinical investigations of Multikine, presented at ESMO (Europe Society for Medical Oncology) in October 2023, have demonstrated in the randomized controlled Phase III trial (RCT) the following in the target population:

·  ***<u>risk of death cut in half at five years</u>*** versus the control;

· 28.6% absolute 5-year overall survival benefit versus control (p=0.0015);

· 0.349 hazard ratio vs control (95% CIs [0.18, 0.66], Wald p=0.0012);

· >35% rate of pre-surgery reductions and/or downstages (p<0.01); and

· low PD-L1 tumor expression (vs high PD-L1 where Keytruda and Opdivo work best).

There were no demonstrable safety signals or toxicities observed in approximately 740 Multikine-treated subjects across multiple clinical trials. Adverse event (AE) and serious adverse event (SAE) incidences were not significantly different among treatment and control groups. There were no Multikine-related deaths, no Multikine-related delays of surgery, no Multikine-related interference with post-surgical treatment, and only two discontinuations. Multikine-related AEs before surgery were local and resolved after surgery. Although the literature reports that some of Multikine's components may be toxic when administered systemically (e.g., TNFα, IFN γ, IL-1β), these toxicities did not emerge with Multikine, even at doses many times higher than those administered in the Phase III trial, primarily due to Multikine's delivery by local injection and dosage.

CEL-SCI published its data as abstracts and posters at the annual conferences for the 2022 American Society of Clinical Oncology (ASCO), 2022 and 2023 European Society for Medical Oncology (ESMO), the 2023 European Head and Neck Society's (EHNS's) annual European Conference on Head and Neck Oncology (ECHNO), the 2023 European Society for Therapeutic Radiology and Oncology (ESTRO) and the 2023 American Head and Neck Society (AHNS). These publications can be accessed at <u>http://www.cel-sci.com</u>.

**<u>Multikine</u> <u>works by inducing pre-surgical responses.</u>** CEL-SCI observed statistically significant pre-surgical responses after Multikine treatment, and therefore CEL-SCI believes in the following:

➢ Multikine causes pre-surgical responses;

➢ Pre-surgical responses lead to longer life;

➢ Therefore, selecting more patients predicted to have a pre-surgical response should lead to much better survival in the target population.

A "pre-surgical response" is a significant change in disease before surgery. CEL-SCI saw two kinds of responses in the Phase III trial. First, there were "reductions" in the size of the tumor—a reduction of 30% or more qualified as a "pre-surgical reduction," or "PSR" for short. Second, there were disease "downstages" (e.g., the disease improved from Stage IV to Stage III) pre-surgery. CEL-SCI calls this a "pre-surgical downstaging" or "PSD" for short. CEL-SCI's 2022 ESMO cancer conference presentation reported on PSR, and CEL-SCI's new 2023 ESMO presentation reported on PSD.

Across the whole Phase III trial, PSRs were seen in 8.5% of Multikine patients compared to *<u>none</u>* in the control group. PSDs were seen in 22% of Multikine patients as compared to 13% in the control group. Because Multikine was the only therapy given to these patients before surgery, it is CEL-SCI's strong belief that Multikine had to be the cause of the higher rates of PSR and PSD.

These data are presented visually below. The taller blue columns show PSR and PSD rates in all 529 Multikine-treated patients in the Phase III trial, and the gray columns show PSR and PSD rates for all 394 control patients.

It was not enough for us to show that Multikine likely leads to PSRs and PSDs as compared to a control group, CEL-SCI also had to test if PSRs and PSDs lead to improved survival. CEL-SCI's Phase III trial demonstrated that PSR patients were 72% likely to be alive after five years, whereas control patients were only about 49% likely to be alive after five years. Patients with PSD saw similar improvement in CEL-SCI's Phase III trial. Their five-year chance of survival was approximately 68%. Therefore, CEL-SCI believes that the Phase III trial demonstrated that those patients who had PSR or PSD resulting from Multikine lived longer than those who were not treated with Multikine. It is important to note that these results are from the entire Phase III study population, not from a subgroup. The likelihood of living at least five years is shown in the graphic below for patients with PSR (blue), patients with PSD (orange) and control patients who did not receive Multikine (gray).

**<u>Multikine cut the 5-year risk of death in half in the target population.</u>** CEL-SCI's results show that Multikine can cut the risk of death in half at five years versus the control group in the target population. Survival increased from 45% in the control group to 73% in the Multikine group at five years. This means the risk of death fell to 27% in the Multikine group from 55% in the control, shown below.

![](cvm_s3img17.jpg)

Another way to see the survival benefit of Multikine in the target population is the Kaplan-Meier curve from our ESMO '23 poster, shown below. On the vertical axis is the probability of survival and the horizontal axis is time in months. The blue Multikine line is far above the green control line, meaning the chance of survival is much higher in the Multikine group at every point in time compared to the control. These results had a low (log rank) p-value of 0.0015, which is very significant as a statistical matter.

CEL-SCI's physician consultants have informed CEL-SCI that the early separation of these two survival curves (e.g., at 12 months) adds validation to the potential positive effects of Multikine.

Another measure of survival benefit is called the "hazard ratio," which compares the rate of an event (chances) of dying between two different groups. Here, in the Multikine target population, the hazard ratio was 0.35, which means that deaths occurred in the Multikine group about one-third as frequently as in the control group. It is also important to note that the hazard ratio's 95% confidence interval remained far below 1.0 (which would mean parity between the compared groups). In the case of Multikine, statistically speaking, there is a 95% chance that the hazard ratio would fall between 0.18 and 0.66 if Multikine were tested in the target population in another study. A hazard ratio of 0.66 as the "so called worst case scenario" (the upper limit of the 95% confidence interval - for the hazard ratio - in this case) is still below (better) than the hazard ratio required for most drug approvals.

CEL-SCI completed a bias analysis for the target population in the Phase III study in preparation for submission of data to regulatory agencies including the FDA for confirmatory registration study. The detailed data on parameters including patient age, sex, race, tumor locations, and staging demonstrate balance between the treatment and control arms. Therefore, no bias was found, which supports confidence in Multikine's efficacy results.

![](cvm_s3img19.jpg)

These positive survival outcomes—increased overall survival, reduced risk of death, widely separated Kaplan-Meier curves with early separation, low hazard ratio, low p-values, low confidence intervals—CEL-SCI believes were driven by high PSR/PSD rates in the target population, as shown in the graphic below:

![](cvm_s3img20.jpg)

CEL-SCI relies on all of these data together to support its plan to request accelerated/conditional approval in the new target population without waiting until the completion of another clinical trial. CEL-SCI's regulatory strategy going forward is to seek approval of Multikine following full enrollment of our confirmatory study wherever possible.

CEL-SCI applied to the FDA for a 212-patient randomized controlled confirmatory registration study focusing only on those patients in the target population, which accounts for approximately 100,000 patients worldwide per year. In May 2024, CEL-SCI announced that the FDA indicated CEL-SCI may move forward with a confirmatory registration study of Multikine in the target population.

· The confirmatory study will be a randomized controlled trial with two arms: Multikine treatment plus standard of care versus standard of care alone.

· If approved as a pre-surgical treatment, CEL-SCI believes Multikine should be added to the standard of care for the target population in this unmet medical need.

· CEL-SCI believes that the confirmatory study has a high likelihood of success based on the large survival benefit that has already been observed in the target population from the completed Phase III study. The planned confirmatory study will be much smaller—less than a quarter the size of the prior study— and will focus on the patients who saw the greatest survival benefit when treated with Multikine.

**Why Do We Believe Our Confirmatory Study Will Be Successful?**

![](cvm_s3img21.jpg)

An "unmet need" is a factor for approval considered by all major regulatory bodies worldwide. In the Multikine target population, there is also a great unmet need for improved survival. The current standard of care provides only about a 50/50 chance of surviving five years, whereas Multikine could increase that survival rate to over 70% in the target population based on the Phase III data. Chemotherapy (in addition to radiotherapy following surgery) has improved survival outcome for some head and neck patients, but chemotherapy is only indicated for high-risk patients, who are not likely to fall within the Multikine target population. Currently available immunotherapies are given after surgery or where surgery is not indicated, in contrast to Multikine, which is given before surgery to patients with resectable tumors. Available checkpoint inhibitors work best on tumors with high PD-L1 expression, whereas Multikine works best in tumors with low PD-L1 expression. Therefore, Multikine's target population is underserved, and will continue to be underserved, by current therapies.

The major regulatory bodies with whom we are working, U.S. FDA, Health Canada, European Medicines Agency (EMA) and the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (UK) all have conditional approval pathways designed for situations where the target population has not been fully tested prospectively and there is strong data supporting clinical benefit for patients. The reason is that regulators understand that in many cases patients should not have to wait for additional data before being offered the chance to benefit from a new drug, especially if the drug has been shown to be safe. Every situation is different and depends on the specific facts.

**IN CONCLUSION**

· **Strong survival data**: Multikine-treated patients in the target population had a 73% 5-year survival vs a 45% 5-year survival in the control group who did not receive Multikine in the Phase III study. In addition, no safety signals or toxicities versus standard of care. The Hazard ratio is 0.35 with an upper limit (95% Confidence Interval) of 0.66.

· **Addressing an unmet medical need**: Multikine focuses on the 70% of patients (based on our 928 patient Phase 3 study) not well served by Keytruda.

· **Multikine's Target Population**: The confirmatory registration study will focus on newly diagnosed locally advanced primary head and neck cancer patients with no lymph node involvement (determined via PET scan) and with low PD-L1 tumor expression (determined via biopsy).

· **FDA pathway**: CEL-SCI's goal is to begin the 212-patient confirmatory registration study as soon as the needed capital has been raised, with full enrollment about 15 months later with the potential to seek early approval after full enrollment.

**SELECTED FINANCIAL DATA REFLECTING REVERSE STOCK SPLIT**

**Reverse Stock Split**

On May 20, 2025, we effected a 1-for-30 reverse stock split of our common stock. Based on such reverse stock split, the total number of outstanding shares of common stock was adjusted from 94,037,256 to approximately 3,135,021. The par value per common share remained unchanged at $0.01. The audited consolidated financial statements of CEL-SCI Corporation included in the Annual Report on Form 10-K for the year ended September 30, 2024, and the unaudited condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2024 and March 31, 2025, which are incorporated by reference into this prospectus are presented without giving effect to the reverse stock split. Except where the context otherwise requires, share numbers in this prospectus supplement reflect the 1-for-30 reverse stock split of our common stock.

The following selected financial data has been derived from our audited consolidated financial statements included in our Annual Report on Form 10-K filed with the SEC on January 13, 2025, and our unaudited condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q filed with the SEC on February 14, 2025 and May 14, 2025, as adjusted to reflect the reverse stock split for all periods presented. Our historical results are not indicative of the results that may be expected in the future and results of interim periods are not indicative of the results for the entire year.

Holders of common stock are entitled to receive dividends as may be declared by the Board of Directors out of legally available funds and, in the event of liquidation, to share pro rata in any distribution of CEL-SCI's assets after payment of liabilities. The Board of Directors is not obligated to declare a dividend. CEL-SCI has not paid any dividends on its common stock and CEL-SCI does not have any current plans to pay any common stock dividends.

The provisions in CEL-SCI's Articles of Incorporation relating to CEL-SCI's preferred stock would allow CEL-SCI's directors to issue preferred stock with rights to multiple votes per share and dividend rights which would have priority over any dividends paid with respect to CEL-SCI's common stock. The issuance of preferred stock with such rights may make the removal of management more difficult, even if such removal would be considered beneficial to shareholders generally, and will have the effect of limiting shareholder participation in certain transactions such as mergers or tender offers if such transactions are not favored by incumbent management.

The market price of CEL-SCI's common stock, as well as the securities of other biopharmaceutical and biotechnology companies, have historically been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Factors such as fluctuations in CEL-SCI's operating results, announcements of technological innovations or new therapeutic products by CEL-SCI or its competitors, governmental regulation, developments in patent or other proprietary rights, public concern as to the safety of products developed by CEL-SCI or other biotechnology and pharmaceutical companies, and general market conditions may have a significant effect on the market price of CEL-SCI's common stock.

**DILUTION**

As of March 31, 2025, we had a net tangible book value of $2.79 per share. An investor purchasing shares pursuant to any prospectus supplement we subsequently file will suffer dilution equal in amount to the difference between the price paid for the securities we offer and our net tangible book value at the time of purchase.

**PLAN OF DISTRIBUTION**

CEL-SCI may sell shares of its common stock, preferred stock, convertible preferred stock, rights, warrants, or units consisting of any of the foregoing, as well as any securities issuable upon the conversion of preferred stock or upon the exercise of warrants in and/or outside the United States: (i) through underwriters, placement agents, or dealers; (ii) directly to a limited number of purchasers or to a single purchaser; or (iii) through agents. The applicable prospectus supplement with respect to the offered securities will set forth the name or names of any underwriters or agents, if any, the purchase price of the offered securities and the proceeds to CEL-SCI from such sale, any delayed delivery arrangements, any underwriting discounts, commissions, and other items constituting underwriters' or placement agents' compensation, the public offering price and any discounts or concessions allowed or reallowed or paid to dealers and any compensation paid to an underwriter or a placement agent. The public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Notwithstanding the above, the maximum commission or discount to be received by any NASD member or independent broker-dealer will not be greater than 10% in connection with the sale of any securities offered by means of this prospectus or any related prospectus supplement, exclusive of any non-accountable expense allowance. Any securities issued by CEL-SCI to any FINRA member or independent broker-dealer in connection with an offering of CEL-SCI's securities will be considered underwriting compensation and may be restricted from sale, transfer, assignment, or hypothecation for a number of months following the effective date of the offering, except to officers or partners (not directors) of any underwriter or member of a selling group and/or their officers or partners.

CEL-SCI's securities may be sold:

· At a fixed price.

· As the result of the exercise of warrants or rights, or the conversion of preferred shares, at fixed or varying prices, as determined by the terms of the warrants, rights or convertible securities.

· At varying prices in "at the market" offerings.

· In privately negotiated transactions, at fixed prices which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

If underwriters are used in the sale, the offered securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The underwriter or underwriters with respect to a particular underwritten offering of securities will be named in the prospectus supplement relating to such offering and, if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover of such prospectus supplement. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent and the underwriters may be obligated to purchase all the offered securities if any are purchased.

If dealers are used in the sale of offered securities in respect of which the prospectus supplement is delivered, CEL-SCI will sell the offered securities to the dealers as principals. The dealers may then resell the offered securities to the public at varying prices to be determined by the dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to the securities sold to the dealers.

If an agent is used in an offering, the agent will be named, and the terms of the agency will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, an agent will act on a best efforts basis for the period of its appointment.

The securities may be sold directly by CEL-SCI 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 resale of the securities purchased by the institutional investors. The terms of any of the sales, including the terms of any bidding or auction process, will be described in the applicable prospectus supplement.

CEL-SCI may permit agents or underwriters to solicit offers to purchase its securities at the public offering price set forth in a prospectus supplement pursuant to a delayed delivery arrangement providing for payment and delivery on the date stated in the prospectus supplement. Any delayed delivery contract will contain definite fixed price and quantity terms. The obligations of any purchaser pursuant to a delayed delivery contract will not be subject to any market outs or other conditions other than the condition that the delayed delivery contract will not violate applicable law. In the event the securities underlying the delayed delivery contract are sold to underwriters at the time of performance of the delayed delivery contract, those securities will be sold to those underwriters. Each delayed delivery contract shall be subject to CEL-SCI's approval. CEL-SCI will pay the commission indicated in the prospectus supplement to underwriters, dealers or agents soliciting purchases of securities pursuant to delayed delivery arrangements accepted by CEL-SCI.

Notwithstanding the above, while prospectus supplements may provide specific offering terms, or add to or update information contained in this prospectus, any fundamental changes to the offering terms will be made by means of a post-effective amendment.

Agents, dealers and underwriters may be entitled under agreements entered into with CEL-SCI to indemnification from CEL-SCI against certain civil liabilities, including liabilities under the Securities Act, or to contributions with respect to payments made by such agents, dealers or underwriters.

**DESCRIPTION OF SECURITIES**

**<u>Common Stock</u>**

CEL-SCI is authorized to issue 600,000,000 shares of common stock, (the "common stock"). Holders of common stock are each entitled to cast one vote for each share held of record on all matters presented to shareholders. Cumulative voting is not allowed; hence, the holders of a majority of the outstanding shares of our common stock can elect all directors.

Holders of common stock are entitled to receive such dividends as may be declared by the Board of Directors out of funds legally available therefor and, in the event of liquidation, to share pro rata in any distribution of CEL-SCI's assets after payment of liabilities. The board is not obligated to declare a dividend. It is not anticipated that dividends will be paid in the foreseeable future.

Holders of common stock do not have preemptive rights to subscribe to additional shares if issued by CEL-SCI. There is no conversion, redemption, sinking fund or similar provision regarding the common stock. All of the outstanding shares of common stock are fully paid and non-assessable.

**<u>Preferred Stock</u>**

CEL-SCI is authorized to issue up to 200,000 shares of preferred stock. CEL-SCI's Articles of Incorporation provide that the Board of Directors has the authority to divide the preferred stock into series and, within the limitations provided by Colorado statute, to fix by resolution the voting power, designations, preferences, and relative participation, special rights, and the qualifications, limitations or restrictions of the shares of any series so established. As the Board of Directors has authority to establish the terms of, and to issue, the preferred stock without shareholder approval, the preferred stock could be issued to defend against any attempted takeover of CEL-SCI. As of June 30, 2025, no shares of preferred stock were outstanding.

**<u>Rights Agreement</u>**

In October 2020, we declared a dividend of one Series A Right and one Series B Right, or collectively the Rights, for each share of our common stock which was outstanding on October 30, 2020. When the Rights become exercisable, each Series A Right will entitle the registered holder, subject to the terms of a Rights Agreement, to purchase from us one share of our common stock at a price equal to 20% of the market price of our common stock on the exercise date, although the price may be adjusted pursuant to the terms of the Rights Agreement. If after a person or group of affiliated persons has acquired 15% or more of our common stock or following the commencement of a tender offer for 15% or more of our outstanding common stock (i) we are acquired in a merger or other business combination and we are not the surviving corporation, (ii) any person consolidates or merges with us and all or part of our common shares are converted or exchanged for securities, cash or property of any other person, or (iii) 50% or more of our consolidated assets or earning power are sold, proper provision will be made so that each holder of a Series B Right will thereafter have the right to receive, upon payment of the exercise price of $100 (subject to adjustment), that number of shares of common stock of the acquiring company which at the time of such transaction has a market value that is twice the exercise price of the Series B Right.

The description and terms of the Rights are set forth in a Rights Agreement between the Company and Computershare Trust Company, N.A., as Rights Agent.

***Distribution of Rights***

Initially, stockholders will not receive separate certificates for the Rights as the Rights will be represented by outstanding common stock certificates. Until the exercise date, the Rights cannot be bought, sold or otherwise traded separately from the common stock. Certificates for common stock carry a notation that indicates that Rights are attached to the common stock and incorporate the terms of the Rights Agreement.

Separate certificates representing the Rights will be distributed as soon as practicable after the earliest to occur of:

· 15 business days following a public announcement that a person or group of affiliated or associated persons has acquired beneficial ownership of 15% or more of our outstanding common stock, or

· 15 business days (or such later date as may be determined by action of our board of directors prior to such time as any person or group of affiliated persons has acquired 15% or more of our common stock) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in the beneficial ownership by a person or group of 15% or more of our outstanding common stock.

The earlier of such dates described above is called the "distribution date."

Until the distribution date (or earlier redemption or expiration of the Rights), the surrender or transfer of any certificates for common stock outstanding as of the record date, even without such notation, will also constitute the transfer of the Rights associated with the common stock represented by such certificate. As soon as practicable following the distribution date, separate certificates evidencing the Rights will be mailed to holders of record of the common stock as of the close of business on the distribution date and such separate right certificates alone will evidence the Rights.

***Exercise and Expiration***

The holders of the Rights are not required to take any action until the Rights become exercisable. The Rights are not exercisable until the distribution date. Holders of the Rights will be notified by us that the Rights have become exercisable. The Rights will expire on October 30, 2025, unless the expiration date is extended or unless the Rights are earlier redeemed by us as described below.

***Redemption***

At any time prior to the distribution date, our board of directors may redeem the Rights in whole, but not in part, at a price of $0.0001 per Right. Subject to the foregoing, the redemption of the Rights may be made effective at such time, on such basis and with such conditions as our board of directors in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only entitlement of the holders of Rights will be to receive the redemption price.

***Exchange Option***

At any time after a person or group of affiliated persons has acquired 15% or more of our common stock or following the commencement of a tender offer for 15% or more of our outstanding common stock, and prior to the acquisition by such person of 50% or more of the outstanding common stock, our board of directors may exchange the Rights (other than Rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock per Right (subject to adjustment).

---

| |
|:---|
| 18 |
| *[**Table of Contents**](#TOC)* |

---

***Other Provisions***

The terms of the Rights may be amended by our board of directors without the consent of the holders of the Rights, except that from and after such time a person or group of affiliated persons has acquired 15% or more of our common stock no such amendment may adversely affect the interests of the holders of the Rights.

Until a Right is exercised, the holder of the Right, as such, will not have any rights as a stockholder, including, without limitation, the right to vote or to receive dividends.

The Rights may have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors. However, the Rights should not interfere with any merger or other business combination approved by a majority of our board of directors because the Rights may be redeemed by us at any time prior to the distribution date. Thus, the Rights are intended to encourage persons who may seek to acquire control of us to initiate such an acquisition through negotiations with our board of directors. However, the effect of the Rights may be to discourage a third party from making a partial tender offer or otherwise attempting to obtain a substantial position in the equity securities of, or seeking to obtain control of, us. To the extent any potential acquisition is deterred by the Rights, the Rights may have the effect of preserving incumbent management in office.

***Attorneys' Fees in Stockholder Actions***

Our bylaws include a fee-shifting provision in Article X for stockholder claims. Article X provides that in the event that any stockholder initiates or asserts a claim against us, or any of our officers or directors, including any derivative claim or claim purportedly filed on our behalf, and the stockholder does not obtain a judgment on the merits that substantially achieves, in substance and amount, the full remedy sought, then the stockholder will be obligated to reimburse us and any of our officers or directors named in the action, for all fees, costs and expenses of every kind and description, including but not limited to all reasonable attorneys' fees and other litigation expenses, that we or our officers or directors who were named in the action may incur in connection with such claim.

Our fee-shifting provision is not limited to specific types of actions, but is rather potentially applicable to the fullest extent permitted by law. There are several types of remedies that a stockholder may seek in connection with an action or proceeding against us, including declaratory or injunctive relief, or monetary damages. If a stockholder is not successful in obtaining a judgment that substantially achieves in substance, such as in the case of a claim for declaratory or injunctive relief, or amount, such as in the case of a claim for monetary damages, our and our officers' and directors' litigation expenses may be shifted to the stockholder.

Fee-shifting provisions are relatively new and untested. The case law and potential legislative action on fee shifting bylaws are evolving and there exists considerable uncertainty regarding the validity of, and potential judicial and legislative responses to, such bylaws. For example, it is unclear whether our ability to invoke our fee-shifting bylaw in connection with claims under the federal securities laws, including claims related to this offering, would be pre-empted by federal law. Similarly, it is unclear how courts might apply the standard that a stockholder must obtain a judgment that substantially achieves, in substance and amount, the full remedy sought. The application of our fee shifting bylaw in connection with such claims, if any, will depend in part on future developments of the law. We cannot assure you that we will or will not invoke our fee-shifting bylaw in any particular dispute, including any claims related to this offering.

---

If a stockholder that brings any such claim is unable to obtain the required judgment, the attorneys' fees and other litigation expenses that might be shifted to such a stockholder are potentially significant. This fee-shifting bylaw, therefore, may dissuade or discourage stockholders (and their attorneys) from initiating lawsuits or claims against us or our directors and officers. In addition, it may impact the fees, contingency or otherwise, required by potential plaintiffs' attorneys to represent our stockholders or otherwise discourage plaintiffs' attorneys from representing our stockholders at all. As a result, this bylaw may limit the ability of stockholders to affect the management and direction of our company, particularly through litigation or the threat of litigation.

**<u>Transfer Agent</u>**

Computershare, Inc., of Denver, Colorado, is the transfer agent for CEL-SCI's common stock.

**LEGAL MATTERS**

The validity of the securities being offered by this prospectus will be passed upon for us by Hart & Hart, Denver, Colorado.

**EXPERTS**

The financial statements of CEL-SCI Corporation (the Company) as of September 30, 2024 and 2023 and for each of the two years in the period ended September 30, 2024 incorporated by reference in this Registration Statement have been so incorporated in reliance on the reports of BDO USA, P.C., an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting. The report on the financial statements contains an explanatory paragraph regarding the Company's ability to continue as a going concern.

**INDEMNIFICATION**

CEL-SCI's bylaws authorize indemnification of a director, officer, employee or agent of CEL-SCI against expenses incurred by such person in connection with any action, suit, or proceeding to which such person is named a party by reason of such person having acted or served in such capacity, except for liabilities arising from such person's own misconduct or negligence in performance of such person's duty. In addition, even a director, officer, employee, or agent of CEL-SCI who was found liable for misconduct or negligence in the performance of his duty may obtain such indemnification if, in view of all the circumstances in the case, a court of competent jurisdiction determines such person is fairly and reasonably entitled to indemnification. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, or persons controlling CEL-SCI pursuant to the foregoing provisions, CEL-SCI has been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

**ADDITIONAL INFORMATION**

CEL-SCI is subject to the requirements of the Securities Exchange Act of l934 and is required to file 10-K, 10-Q, 8-K reports, proxy statements and other information with the Securities and Exchange Commission. The Commission maintains an Internet site that contains reports, proxy and information statements, and other information regarding CEL-SCI. The address of that site is http://www.sec.gov.

**Item 17. <u>Undertakings</u>**.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement.

(i) To include any prospectus required by Section l0(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement, including (but not limited to) any addition or deletion of a managing underwriter.

(2) That, for the purpose of determining any liability under the Securities Act of l933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

Insofar as indemnification for liabilities arising under the Securities Act of l933 (the "Act") may be permitted to directors, officers and controlling persons of the Registrant, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
