### Overview

HCW Biologics Inc. (“HCW Biologics” or the “Company”) is a clinical-stage biopharmaceutical company developing transformative fusion immunotherapeutics to treat diseases promoted by chronic inflammation. We have created novel compounds that represent a new class of drugs that we believe have the potential to fundamentally change the treatment of autoimmune disorders and other inflammatory diseases, cancer and senescence-associated dysplasia. In addition, we have begun commercialization of certain commercial-ready proprietary compounds for use as reagents to support the production of immunotherapeutics for the treatment of infectious diseases and cancer.

By leveraging our extensive immunology expertise, we have developed fusion immunotherapeutics representing a new class of drug that we believe has the potential to fundamentally change the treatments for autoimmune diseases, cancer, senescence-associated dysplasia, and many other diseases promoted by chronic inflammation — and in doing so, improve patients’ quality of life and possibly extend longevity.

HCW Biologics has an experienced team led by Dr. Hing C. Wong, our Founder and CEO, who discovered and developed the immunotherapeutic Anktiva® (also known as ALT-803, an IL-15 receptor agonist) through pivotal trials. This blockbuster immunotherapeutic treatment for cancer was sold to ImmunityBio, Inc. in 2017 in a $1.0 billion acquisition. In April 2024, Anktiva® was approved by the U.S. Food and Drug Administration for its first indication, the treatment of BCG-Unresponsive Non-Muscle Invasive Bladder Cancer in combination with BCG.

### Business Highlights

### Reverse Stock Split

The Company completed a one-for-six reverse stock split on June 30, 2026 (the “Reverse Stock Split”). All share amounts and price per share amounts discussed herein reflect the Reverse Stock Split.

### Financing

#### May 2026 Sale of Common Stock, Pre-Funded Warrants and Common Stock Warrants

On May 21, 2026, the Company completed a $4.0 million private placement with a group of existing stockholders, in which the Company sold 474,496 units, each of which consisted of one share of Common Stock, or a Pre-Funded Warrant in lieu thereof, and a Common Stock Warrant to purchase one share of Common Stock. Net proceeds to the Company after placement agent commissions and offering costs were $3.5 million. On June 18, 2026, the SEC declared effective a resale registration statement on Form S-1 (File No. 333-296577) covering the resale of shares of Common Stock and warrants issued in this private placement. Investors included a single institutional investor and certain of our directors and executive officers. Scott Garrett, Chairman of our board of directors, purchased $250,000 of securities, Hing C. Wong, our Founder and Chief Executive Officer, purchased $160,000 of securities, and Rebecca Byam, our Chief Financial Officer, purchased $20,000 of securities. Such purchases were made on the same terms and conditions as those offered to other investors. On June 22, 2026, the holder exercised all Pre-Funded Warrants issued in this transaction to purchase 403,322 shares of Common Stock for $0.0001 per share.

#### July 2026 Sale of Units Comprised of Common Stock, Pre-Funded Warrants and Rights to Receive Common Stock Warrants

Subsequent to June 30, 2026, on July 29, 2026, the Company completed a private placement with certain accredited investors in which the Company sold 618,682 units, each unit consisting of one share of Common Stock, or a Pre-Funded Warrant in lieu thereof, and (ii) the right to receive one Common Stock Warrant upon, and subject to, stockholder approval of the issuance of such Common Stock Warrants, which approval the Company is obligated to seek pursuant to the terms of the purchase agreement. Gross proceeds of the offering were approximately $1.6 million before deducting offering expenses. Hing C. Wong, Ph.D., our Founder and Chief Executive Officer, Scott Garrett, Chairman of our board of directors, and Lee Flowers, our Senior Vice President of Business Development, participated in the private placement on the same terms and conditions as the other investor.

#### Preparing for Business Development Transaction for Commercial-Ready Reagents

Two of our internally-developed, multi-cytokine fusion protein molecules, HCW9201 and HCW9206, were licensed to AlloTera Therapeutics in 2020. During 2025, AlloTera Therapeutics was refocusing its clinical development programs, and the Company agreed to a suspension of the AlloTera Therapeutics License. On May 21, 2026, the Company elected to terminate the AlloTera Therapeutics License according to the terms provided in the suspension agreement.

We are positioning HCW9206 and HCW9201 as commercial-ready reagents for use in supporting the manufacture of cell-based immunotherapeutics to treat cancer and infectious diseases. The extensive research done in collaboration with the Albert Einstein College of Medicine showed that HCW9206 and similar molecules developed by the Company appear to support more efficient production of CAR-T cells that keep fighting disease longer. We intend to enter into a commercialization partnership with a biopharmaceutical manufacturing company in the second half of 2026.

Since inception in December 2020, the Company has recognized $16.2 million in revenue derived from the AlloTera Therapeutics License, including upfront license fees in cash and shares of AlloTera Therapeutics common stock, purchases of the Company’s inventory of certain molecules needed for manufacturing, and purchases of materials for its clinical trials. In addition, the Company received over $1.8 million in reimbursements for its R&D expenses. The upfront license fee is nonrefundable, and as such, the Company retains ownership of the 2.2 million shares of AlloTera Therapeutics common stock.

#### Settlement of Accounts Payable Obligations

The Company continues to strengthen its balance sheet through repayment and restructuring of obligations. In the three months ended June 30, 2026, the Company settled $2.8 million of overdue accounts payable, including $1.1 million owed to B&I Contractors, Inc. (“B&I”) and $1.7 million owed to Eirgenix. Settlement terms fully resolved all amounts claimed to be owed by the Company to these vendors. In the three months ended June 30, 2026, the Company paid Eirgenix $620,000 and paid B&I $512,655. In the six months ended June 30, 2026, the Company paid Eirgenix $1,240,000 and paid B&I $865,655.

#### Nasdaq Compliance

On June 26, 2025, the Company received formal notice from The Nasdaq Stock Market LLC (“Nasdaq”) that the Company is in compliance with Listing Rule 5550(b)(1) (the “Equity Rule”). On June 29, 2026, the Company received written notice from the Nasdaq Listing Staff that the Nasdaq Hearings Panel found that the Company had regained compliance with the Bid Price Rule, subject to certain restrictions. The Company will be subject to a Mandatory Panel Monitor until June 17, 2027. See Part II, Item 1, “Legal Proceedings – Other Matters.”

### Clinical Development

#### Preliminary Human Data Readout for Phase 1 Clinical Study Evaluating HCW9302 as Monotherapy in Alopecia Areata

On June 16, 2026, the Company disclosed a preliminary human data readout for the Phase 1 clinical study evaluating HCW9302 in patients with alopecia areata. The Company believes that based on the human data readout and extensive preclinical studies, HCW9302 is potentially a best-in-class IL-2 based treatment for autoimmune diseases by expanding and activating regulatory T cells. Preliminary results indicate that HCW9302 is well tolerated, with no dose-limiting toxicities or significant known IL-2-treatment-related adverse effects, including no reported incidence of capillary leak syndrome, cytokine release syndrome, or increase in blood eosinophil counts.

The readout was for two dose cohorts in a dose-escalating study. All patients, including the first dose cohort at one (1) microgram/kg body weight and the second dose cohort at three (3) micrograms/kg body weight, received a single subcutaneous dose of HCW9302 monotherapy. In the second dose cohort, all three participants showed preliminary indications of improvement in their Severity of Alopecia Tool (“SALT”) scores. These three participants, all with mild alopecia, showed a ≥25% reduction in SALT scores compared to baseline at four and/or nine weeks after dosing. Treatment of patients in the third dose cohort (i.e., eight (8) micrograms/kg body weight) is underway and evaluation of correlative study endpoints is ongoing.

There were no reported incidences of capillary leak or cytokine release syndromes associated with high dose intravenous IL-2 therapy. Additionally, HCW9302 treatment did not increase blood eosinophil counts, another serious side effect commonly associated with IL-2 therapy. All reported HCW9302 treatment emergent adverse events were mild in severity and self-limiting and resolved without medical intervention. The most common side effect was temporary injection-site reaction.

Dosing of the third dose cohort is underway at eight (8) micrograms/kg body weight. The Company has not reported any dose limiting toxicities in the patients treated to date. Patient enrollment continues to be strong, and the Company has added a third clinical site to the study. The full Phase 1 human data readout for the HCW9302 study remains on track to be released in the fourth quarter of 2026. Primary endpoints are safety and a recommended Phase 1 dose. Working with collaborators, the Company is conducting ancillary studies to supplement this data.

#### Milestone for HCW11-018b, Leading Product Candidate in Company’s Tetravalent T-Cell Engager Program

The Company requested a Type B (pre-IND application) meeting with the U.S. Food and Drug Administration (“FDA”) to discuss the development and regulatory strategy for its investigational lead product candidate, HCW11-018b, a tetravalent T-cell engager (“TCE”) constructed with the Company’s proprietary TRBC drug development platform. The Company would like to reach agreement with FDA on requirements for a clinical study before we submit an IND application to evaluate HCW11-018b in cancer. This clinical trial is on track to initiate in the first half of 2027, provided we secured FDA authorization.

HCW11-018b is intended to treat solid tumors and is administered by subcutaneous injection. In preclinical studies, it has shown the ability to target tissue factor-expressing cancer cells and activate CD3-positive effector T cells, while simultaneously reducing immunosuppression in the tumor microenvironment. Immunosuppression in the tumor microenvironment can limit effector T-cell infiltration and antitumor activity in solid tumors, particularly in gynecologic and pancreatic cancers.

The Company believes that our robust, streamlined, and cost-efficient manufacturing process will produce high-quality cGMP material to support clinical development. Our manufacturing process for HCW11-018b is based on high-producing recombinant CHO cell lines and a proprietary monoclonal antibody needed for the affinity purification process. This monoclonal antibody will be manufactured under GMP standards using a top-tier CDMO.

TCEs have emerged as a potent therapeutic modality to treat cancer. First-generation TCEs represented a breakthrough in immunotherapy but they continue to face significant challenges, including limited antigen selection, poor efficacy in solid tumors, tolerability and safety concerns, and complex manufacturing processes. Extensive preclinical studies of HCW11-018b —including assessments of *in vitro* and *in vivo* potency, antigen specificity, pharmacokinetics, toxicity in nonhuman primates, and its therapeutic window — suggest that HCW11-018b may be able to overcome the limitations of earlier-generation TCEs.

### Trends and Uncertainties

#### Inflationary Cost Environment, Geopolitical Risks and Other Macroeconomic Factors

The Company’s operations have been affected by many headwinds, including inflationary pressures, tariffs, rising interest rates, ongoing global supply chain disruptions resulting from increased geopolitical tensions such as the war in the Middle East, the conflict between Russia and Ukraine, China-Taiwan relations, financial market volatility and currency movements. The Company has been impacted by inflation, and may continue to be so, when securing materials needed for our operations, the costs for recruiting and retaining employees and other employee-related costs. Management employs a number of strategies to effectively navigate these issues, including product redesign, alternate sourcing, and establishing contingencies in budgeting and timelines. Future developments in these and other areas present material uncertainty and risk with respect to the Company’s clinical trials, IND-enabling activities, as well as the Company’s financial condition and results of operations. The extent and duration of such events and conditions, and resulting disruptions to our operations, are highly unpredictable.

### Components of our Results of Operation

### Revenues

We have no products approved for commercial sale and have not generated any revenue from commercial product sales of internally-developed immunotherapeutic products for the treatment of autoimmune disorders, cancer and senescence-associated dysplasia. Since inception, our sole source of revenue is from license and clinical development supply agreements.

#### AlloTera Therapeutics License

The Company entered the AlloTera Therapeutics License at the end of 2020, and we entered a development supply agreement with them to provide it with clinical development materials needed for research and clinical development in the first quarter of 2021. On May 29, 2025, the Company agreed to a one-year suspension of the AlloTera Therapeutics License, while they assessed the strategic direction of their clinical development programs. On May 21, 2026, the Company elected to terminate the AlloTera Therapeutics License according to the terms of the suspension agreement. The Company has launched a commercial-ready program to commercialize the two molecules formerly licensed to AlloTera Therapeutics as reagents to support the manufacturing process of cell-based immunotherapies for cancer and infectious diseases.

The Company will continue to hold the upfront, nonrefundable license fee from AlloTera Therapeutics, including the in-kind payment of 2.2 million shares of their common stock.

#### Trimmune License

On November 17, 2025, the Company and Beijing Trimmune Biotech Co., Ltd. (“Trimmune”) entered into an Amended and Restated License, Research and Co-Development Agreement (“Trimmune License”) following the assignment of the original License, Research and Co-Development Agreement, which includes an exclusive license to HCW11-006 for in vivo applications (“WY Biotech License”) from WY Biotech Co., Ltd. to Trimmune. The parties restructured the terms of the original WY Biotech License to include the assignment of rights to Trimmune and an option to license HCW9302 for in vivo applications in China or Asia. The Company retained its Opt-In Rights for the Americas market, which we may exercise after Trimmune completes its first Phase 1 clinical study.

On March 16, 2026, the Company received the full nonrefundable upfront license fee, consisting of $3.5 million in gross cash proceeds, or $2.9 million net of taxes, and a transferable minority equity ownership interest in Trimmune with a fair value of $3.5 million, whereupon the transaction was deemed closed and the contract was binding. The Company elected to use the measurement alternative under ASC 321-10-35-2 to account for the investment in Trimmune shares — cost less impairment, with adjustment for observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

In addition to the upfront license fee and Opt-In Rights, the Company is eligible to receive additional development milestone payments and double-digit royalties on future product sales. Further, in the event Trimmune elects to exercise its option to license HCW9302 in China or Asia, the Company will receive additional consideration. None of these elements met the threshold for recognition under Topic 606 as of June 30, 2026.

### Operating Expenses

Our operating expenses are reported as research and development expenses and general and administrative expenses.

#### Research and Development

Our research and development expenses consist primarily of costs incurred for the development of our product candidates, which include:

- Employee-related expenses, including salaries, benefits, and stock-based compensation expense;
- Expenses related to manufacturing and materials, consisting primarily of expenses incurred in connection with CMOs, which produce cGMP materials for clinical trials on our behalf;
- Expenses associated with preclinical activities, including research and development and other IND-enabling activities;
- Expenses incurred in connection with clinical trials; and
- Other expenses, such as facilities-related expenses, direct depreciation costs for capitalized scientific equipment, and allocation for overhead.

We expense research and development costs as they are incurred. Costs for contract manufacturing are recognized based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors. Payments for these activities are based on the terms of the agreement, and the pattern of payments for goods and services will change depending on the material. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses and expensed as the related goods are delivered or the services are performed.

We expect research and development expenses to increase substantially for the foreseeable future as we continue the development of our product candidates. We cannot reasonably determine the nature, timing, and costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates. Product candidates in later stages of development generally have higher development costs than those in earlier stages. See “Risk Factors — Risks Related to the Development and Clinical Testing of Our Product Candidates,” in our Annual Report for a discussion of some of the risks and uncertainties associated with the development and commercialization of our product candidates. Any changes in the outcome of any of these risks and uncertainties with respect to the development of our product candidates in preclinical and clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.

#### General and Administrative

General and administrative expenses consist primarily of employee-related expenses for executive, legal, finance, accounting, human resources and other administrative personnel, as well as professional fees (including legal, audit and tax services), insurance costs, facilities expenses, and other public company compliance costs.

We expect general and administrative expenses incurred in the normal course of business for other purposes, such as costs for recruitment and retention of personnel, service fees for consultants, advisors and accountants, as well as costs to comply with government regulations, corporate governance, internal control over financial reporting, insurance and other requirements for a public company, to continue to increase for the foreseeable future as we build our clinical programs.

#### Legal Expenses (Recoveries), Net

The Company was involved in an Arbitration and related Complaint that were dismissed with prejudice as of December 31, 2024. See Part II, Item 1, “Legal Proceedings – Arbitration, Settlement and General Release.” In the Settlement Agreement, the Company retained exclusive rights to HCW9302 and certain other molecules. The Company anticipates that it will continue to incur legal expenses for patent filings and other matters to protect our intellectual property rights and remain in compliance with the terms of the Settlement Agreement.

#### Indirect Tax Expense and Income Tax Expense

When Trimmune paid the full nonrefundable upfront license fee on March 16, 2026, the Chinese government withheld income taxes of $330,186, which the Company recognized as an expense in the six months ended June 30, 2026 in the accompany condensed statements of operations.

#### Interest Expense

Interest expense includes interest paid on debt. This includes interest due on the Cogent Bank loan, Secured Notes issued by the Company and accretion of original issue discount and accretion of debt issuance costs.

On August 15, 2022, we entered into a loan and security agreement with Cogent Bank to partially fund our purchase of the property we acquired on that same date (the “2022 Loan”). We borrowed $6.5 million under this agreement. Amounts outstanding on the term loan accrue interest at a rate per annum equal to 5.75%. We were obligated to make interest-only payments on this loan from September 2022 through August 2023 and principal and interest payments in 48 equal monthly installments, based on a 25-year maturity schedule, commencing September 15, 2023.

During the three months ended June 30, 2025, certain noteholders agreed to restructure $6.6 million of the principal amount of Secured Notes issued by the Company, including the accumulated accretion of a fixed bonus payable on Maturity Date, and convert to equity. Noteholders who purchased notes for $325,000 did not elect to convert their Secured Notes. The Secured Notes bear interest at an annual rate of 9%, payable quarterly in arrears. They are also entitled to a fixed bonus, payable on the Maturity Date of August 31, 2026, which is accreted on a straight-line basis.

On May 8, 2025, the Company issued a $150,000 promissory note with a personal guarantee from the Company’s Founder and Chief Executive Officer, which has an original issue discount of $75,000 which is accreted on a straight-line basis from the date of issuance to the Maturity Date of February 7, 2026 (the “Secured Promissory Note”). The Company repaid $225,000 on February 6, 2026.

#### Change in Fair Value of Investment and Contingent Liability

The Company received 2.2 million shares of AlloTera Therapeutics as an in-kind payment for a nonrefundable license fee in December 2020. In the second quarter of 2025, the Company elected to account for its shares of AlloTera Therapeutics, previously accounted for under the measurement alternative, at fair value determined using financial valuation techniques and market information available. In May 2025, the Company entered two transactions to restructure and convert debt. The terms of conversion gave the converting Secured Noteholders and holders of Convertible Bridge Notes the right to a portion of the proceeds upon the sale or liquidation of the Company’s AlloTera Therapeutics shares, if such an event occurs, giving rise to a contingent liability. The Company derives the fair value of the contingent liability according to the fair value measured for underlying the AlloTera shares. The Company remeasures the change in fair value of the AlloTera shares and related contingent liability in earnings.

#### Gain on Extinguishment of Liability

From time to time, the Company restructures liabilities and debt obligations to strengthen our balance sheet. When the Company settles the obligation for less than the recorded carrying value, we recognize a gain on debt extinguishment or extinguishment of a liability in earnings during the period in which it is settled.

#### Change in Fair Value of Warrant Liability

As a result of the modification of existing warrants that may be exercised to purchase up to 503,402 shares of Common Stock to lower the strike price from $14.46 to $3.633 per share, the Company classified these warrants as a warrant liability and recognized it at fair value on the date of the modification as of March 31, 2026. On June 15, 2026, the Company’s stockholders approved the repricing of these warrants at the Annual Meeting of Stockholders. The Company recognized the change in fair value of the warrant liability through the period ended June 15, 2026. With the resolution of the contingency for settlement, these warrants were reclassified to equity as of June 15, 2026.

#### Other Income, Net

| Manufacturing and materials | 33,986 | 27,073 | (6,913) | (20)% |
| Preclinical expenses | 146,948 | 158,917 | 11,969 | 8% |

This decrease was primarily attributable to decreases of $24,900 in salaries, benefits and related taxes and $15,448 in expense for stock-based compensation, partially offset by an increase of $23,220 in costs associated with employee benefits.

Manufacturing and materials expense decreased by $6,913, or 20%, from $33,986 for the three months ended June 30, 2025 to $27,073 for the three months ended June 30, 2026.

The Company will continue to incur preclinical expenses for IND-enabling studies for HCW11-018b as well as HCW11-040, the second-generation immune checkpoint inhibitor in the coming year. The Company intends to file an IND-application to seek authorization to evaluate HCW11-018b in a Phase 1 clinical study in patients with cancer in the first half of 2027, and an IND-application to seek authorization to evaluate HCW11-040 in bronchopulmonary dysplasia, a chronic lung disease primarily affecting premature infants, in the second half of 2027.

For the three and six months ended June 30, 2026, the Company recognized revenues of $135,568 and $6.7 million, respectively. The upfront, nonrefundable license fee included a transferable minority equity interest in Trimmune. Since Trimmune is a private company, there is limited ability to liquidate these shares at this time. On May 21, 2026, the Company elected to terminate its exclusive worldwide license with AlloTera Therapeutics. With these reacquired rights, the Company is launching the formerly licensed molecules as commercial-ready reagents to use to support more cost-effective and efficient manufacturing for cell-based immunotherapies for cancer and infectious diseases. Our strategy is to commercialize the reagents in partnership with a biopharmaceutical manufacturing company in a business development transaction, such as a joint venture or license. The Company will retain the 2.2 million shares of AlloTera Therapeutics received as an in-kind payment for a portion of the nonrefundable upfront license fee. AlloTera Therapeutics is a pivotal-stage cell therapy company focused on bringing off-the-shelf CAR-T therapies to patients with T-cell cancers.

In the three months ended June 30, 2026, the Company completed a $4.0 million offering, which provided $3.5 million in net proceeds after commission and offering costs we are responsible for. Investors who participated in this round were existing stockholders, including officers and directors of the Company. Scott Garrett, Chairman of our board of directors, purchased $250,000 of securities, Hing C. Wong, our Founder and Chief Executive Officer, purchased $160,000 of securities, and Rebecca Byam, our Chief Financial Officer, purchased $20,000 of securities. Such purchases were made on the same terms and conditions as those offered to other investors.

On December 30, 2025, the Company entered a settlement agreement with Cooley related to legal fees incurred in connection with the defense of Dr. Wong. As a result of that agreement, the Company, Dr. Wong and Cooley agreed to settle a $7.5 million obligation for $2.0 million in cash and contingent payments up to $5.5 million upon achievement of certain triggering events, all of which were deemed to be remote as of December 31, 2025. In accordance with the terms of the settlement agreement, $500,000 was paid on December 31, 2025. Based on an amendment to the settlement agreement, the Company paid $750,000 on March 20, 2026, and will pay the remaining $750,000 upon the earlier of the completion of a financing for at least $4.0 million in gross proceeds or August 31, 2026. After this settlement, as of June 30, 2026, the Company has a liability of $5.4 million for remaining amounts owed for legal fees related to the Arbitration which continue to remain outstanding.

During the year ended December 31, 2025, certain subcontractors had filed mechanics liens related to unpaid invoices issued in connection with the construction and renovation of a property owned by the Company. On April 17, 2025, the Company received a summons and a copy of a complaint filed by BE&K in the Circuit Court of the 17th Judicial Circuit in and for Broward County, Florida (the “BE&K Complaint”). Other Defendants named in the BE&K Complaint who are subcontractors elected to file counterclaims and cross-claims as part of their responses to the BE&K Complaint. To our knowledge as of the date hereof, Cogent Bank, also named as a Defendant in the BE&K Complaint, has not elected to take legal action at this time. In addition, on April 28, 2025, the Company received a summons and a copy of a complaint filed by Fisk Electric Company (which is a defendant in the BE&K Complaint) in the Circuit Court of the 17th Judicial Circuit in and for Broward County, Florida (the “Fisk Complaint”) against the Company, BE&K, and the other defendants in the BE&K Complaint. The cases have been consolidated. The Company owes BE&K and other lien holders $2.2 million as of June 30, 2026 that was included within Accounts Payable in the accompanying condensed balance sheets. The court has set the BE&K matter for a five-day jury trial in December 2026. There will also be a pretrial conference on November 20, 2026. The Company intends to settle these claims prior to the pre-trial hearing.

On June 26, 2026, as part of a settlement with B&I Contractors, Inc. (“B&I”), we received notice that B&I had filed a voluntary dismissal with prejudice of its crossclaims against us in the matter *BE&K Building Group, LLC v. HCW Biologics Inc., et al.* pending in the Circuit Court of the Seventeenth Judicial Circuit in and for Broward County, Florida. The matter arose from a mechanics’ lien filed by B&I in connection with allegedly unpaid invoices relating to renovation work at our facility located at 3300 Corporate Way, Miramar, Florida, which is being renovated for future office and laboratory use. In connection with the settlement, B&I filed a final satisfaction of lien releasing a lien in the amount of approximately $1.1 million. The dismissal and satisfaction of lien completed the parties’ settlement and fully resolved all amounts claimed to be owed by us to B&I. There was no gain or loss on the settlement with B&I.

On October 24, 2025, the Company was notified by Cogent Bank that it exercised its discretion to make a demand that the Company cure the defaults no later than thirty (30) days after receipt of this letter in strict compliance with Section 7.2(3) of the Loan Agreement by: (i) paying and discharging all of the Claims of Lien and causing satisfactions to be recorded in the Public Records of Broward County, Florida for all of the Claims of Lien, and (ii) resolving all litigation against the Borrower and the mortgaged property described in the Mortgage and causing such claims in the Foreclosure Actions to be dismissed and all related notices of lis pendens to be released. The Company and Cogent Bank are negotiating terms for a forbearance agreement to provide additional time for the Company to comply with the demands Cogent Bank made in their demand letter. As of June 30, 2026, the balance due under the Loan Agreement was $6.1 million.

On May 26, 2026, we paid in full all amounts due under a settlement agreement with EirGenix, Inc. (“EirGenix”), our contract development and manufacturing organization, relating to manufacturing costs. Pursuant to the settlement agreement entered into on December 9, 2025, EirGenix agreed to accept $1.24 million in full satisfaction of approximately $1.7 million of outstanding amounts, provided payment was made by an agreed deadline. We paid $620,000 on March 3, 2026 and the remaining $620,000 on May 26, 2026. As a result, all obligations under the settlement agreement were satisfied and the related unpaid invoices and disputed credits were fully resolved. There was a gain on extinguishment of a liability of $483,383 recognized in the three and six months ended June 30, 2026 related to the settlement with Eirgenix.

The accompanying condensed financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above. The Company believes that substantial doubt exists regarding its ability to continue as a going concern for at least 12 months from the date of issuance of the Company’s condensed financial statements, without additional funding or financial support. After considering management’s plan for financing and funds raised that are probable to occur within one year, as well as that the Company expects to continue to incur losses from operations for the foreseeable future, management concluded that the substantial doubt that existed in its going concern analysis as of June 30, 2026 was not alleviated.

Because of the numerous risks and uncertainties associated with the clinical development and commercialization of immunotherapeutics, we are unable to estimate the exact amount of capital requirements to pursue these activities. Our funding requirements will depend on many factors, including, but not limited to:

- timing, progress, costs, and results of our ongoing preclinical studies and clinical trials of our immunotherapeutic products;
- costs, timing, and outcome of regulatory review of our product candidates;
- number of trials required for regulatory approval;
- whether we enter into any cooperative, collaboration or co-development agreements and the terms of such agreements;
- whether we raise additional funding through bank loan facilities, other debt arrangements, out-licensing or joint ventures, cooperative agreements or strategic collaborations;
- effect of competing technology and market developments;
- cost of maintaining, expanding, and enforcing our intellectual property rights;
- impact of future arbitration, litigation, regulatory inquiries, or investigations, as well as costs to indemnify our officers and directors against third-party claims related to our patents and other intellectual property:
- cost and timing of buildout of the Company’s property for upgraded research and development facilities, including risks of cost overruns and delays, and ability to obtain additional financing, if needed;
- impact of legal actions taken by BE&K and other lien holders related to foreclosure and other claims; and
- costs and timing of future commercialization activities, including product manufacturing, marketing, sales, and distribution, for any of our product candidates for which we receive regulatory approval.

A change in the outcome of any of these or other factors with respect to the clinical development and commercialization of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Further, our operating plan may change, and we may need additional funds to meet operational needs and capital requirements for clinical trials and other research and development expenditures.

45

#### Operating Activities

Net cash used in operating activities was $6.8 million for the six months ended June 30, 2025 and $5.4 million for the six months June 30, 2026.

Cash used by operating activities for the six months ended June 30, 2025 consisted primarily of net loss for the period of $4.1 million, a $1.7 million adjustment for unrealized gain on investment, a $560,590 decrease in Accounts receivable, a $2.8 million decrease in Accounts payable, and a $131,134 loss on conversion with a related party, partially offset by non-cash adjustments of $710,926 for depreciation and accretion expenses, $553,949 for compensation expenses related to stock-based compensation, and a $150,000 Commitment Fee paid in the Company’s Common Stock. Cash provided by operations includes a $2.0 million insurance reimbursement for legal fees incurred on behalf of Dr. Hing Wong, the Company’s Founder and Chief Executive Officer, for his defense costs associated with the Arbitration, in prior periods, which was paid directly to the law firm involved. See Part II, Item 1, “Legal Proceedings – Arbitration, Settlement and General Release.”

Cash used in operating activities for the six months ended June 30, 2026 consisted primarily of a net loss for the period of $1.7 million, noncash revenue in the form of an in-kind payment of a transferable minority equity interest in Trimmune recognized at the fair value of $3.5 million, $2.0 million of cash used to decrease Accounts payable and other liabilities, a gain on extinguishment of a liability of $483,383 and a $108,214 increase in prepaid expenses and other assets. The uses were partially offset by an increase of $348,270 in Deferred revenue related to contract liabilities under the Trimmune License and noncash adjustments, including a $1.8 million change in fair value of warrant liability, $269,144 for Depreciation and accretion and $11,239 for stock-based compensation.

#### Investing Activities

There was no cash used in or provided by investing activities for the six months ended June 30, 2025 and June 30, 2026, respectively.

#### Financing Activities

During the six months ended June 30, 2025, $4.6 million of cash provided by financing activities consisted of the following:

- $1.5 million of gross proceeds for the issuance of shares of the Company’s Common Stock.
- $5.0 million in gross proceeds for the issuance of Pre-Funded Warrants and Common Stock Warrants.
- $150,000 in gross proceeds upon the issuance of a promissory note secured by a personal guarantee by the Company’s Founder and Chief Executive Officer.

46

In the six months ended June 30, 2025, there were significant noncash transactions. The Company restructured $7.4 million of Secured Notes and accumulated accretion for a fixed bonus payable upon Maturity Date, in exchange for shares of Common Stock, warrants to exercise for Common Stock, and the right to receive proceeds upon the liquidation or sale of a portion of the Company’s shares of AlloTera Therapeutics common stock. Because this was a transaction with related parties, the gain from restructuring was recorded to additional paid-in capital for the period ended June 30, 2025. Also during this period, the Company closed on a $5.0 million financing in which it issued shares of the Company’s Common Stock, warrants to exercise to purchase shares of the Company’s Common Stock and repriced previously issued warrants with an existing stockholder of the Company. The Company estimated fair value of the securities issued and repriced warrants was $15.2 million. The difference between the gross proceeds and fair value was recognized as an equity dividend to investor, as this transaction was with an existing stockholder of the Company. The Company recorded a $10.2 million dividend to additional paid-in capital for the period ended June 30, 2025.

In the six months ended June 30, 2026, the Company closed on two financing transactions for $5.5 million in which it issued shares of the Company Common Stock, warrants to exercise to purchase shares of the Company’s Common Stock to investors, including officers, directors and significant existing stockholders of the Company, and repriced previously issued warrants with an existing stockholder of the Company. The Company estimated fair value of the securities issued and repriced warrants was $17.1 million. The difference between the gross proceeds and fair value was recognized as an equity dividend to investors, as both transactions were with an existing stockholder of the Company. The Company recorded a $11.6 million dividend to investors within additional paid-in capital for the period ended June 30, 2026.

### Critical Accounting Policies, Significant Judgements and Use of Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed interim financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgements about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgements and estimates.

### Revenue Recognition

We recognize revenue under the guidance of Topic 606. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of Topic 606, we perform the following five steps: (i) identification of the contract(s) with the customer, (ii) identification of the promised goods or services in the contract and determination of whether the promised goods or services are performance obligations, (iii) measurement of the transaction price, (iv) allocation of the transaction price to the performance obligations, and (v) recognition of revenue when (or as) we satisfy each performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to our customer. See Note 1 to our condensed financial statements appearing elsewhere in this Quarterly Report on Form 10-Q for more information.

### Earnings per Share

The Company computes basic and diluted earnings per share using the two-class method because certain warrants the Company issued are a participating security that contractually participates with the Company’s Common Stock in any cash dividend or other distribution declared on the Common Stock on an as-converted basis (the “Participating Warrants”). These warrants do not have a contractual obligation to share in the Company’s losses.

Under the two-class method, net income is allocated between Common Stockholders and the holders of the Participating Warrants based on their respective participation rights, and is computed using the more dilutive of (i) the two-class method with dilutive common share equivalents included in the denominator, with a corresponding reallocation of undistributed earnings, or (ii) the if-converted method, which adds preferred-as-converted shares to both the numerator (adding back preferred dividends) and the denominator. For periods in which the Company reports a net loss, no portion of the loss is allocated to the Participating Warrants. The Company reports distributed and undistributed allocations of earnings on a cumulative period basis in accordance with contractual participation rights. As of June 30, 2026, there were participating warrants outstanding that may be exercised to purchase up to 524,501 shares of Common Stock.

Basic loss per share is computed by dividing net loss attributable to Common Stockholders by the weighted-average number of common shares outstanding during the period. Diluted loss per share gives effect to all potentially dilutive common shares outstanding during the period, including employee stock options and Common Stock Warrants, using the treasury stock method. Potentially dilutive securities, including warrants that may be exercised to purchase up to 1,411,870 shares of Common Stock and options that may be exercised to purchase up to 7,342 shares of Common Stock, are excluded from the diluted loss per share computation when their effect would be anti-dilutive.

Other than the above, there have been no material changes to our critical accounting policies and estimates from those described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies, Significant Judgements and Use of Estimates” in our Annual Report.

### Recent Accounting Pronouncements

As of December 31, 2026, the Company will cease to be an ‘emerging growth company’ as defined in the Jumpstart Our Business Startups Act of 2012. We expect to remain a nonaccelerated filer and smaller reporting company. The Company is currently assessing potential regulatory and operational changes that may be required as a result.

See also Note 1 to our Annual Report.

## Market risk

As filed, 625 characters.

As of June 30, 2026, we had cash and cash equivalents of $741,324 including cash, cash equivalents and market investments. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. We are exposed to market risk related to the marketability of investments in private companies, consisting of our AlloTera Therapeutics common stock and our Trimmune shares, reported within Investments in the accompanying condensed balance sheet. Until such time as these shares become publicly traded, we will have limited ability to liquidate these securities.

## Controls and procedures

As filed, 8,584 characters.

### Evaluation of Disclosure Controls and Procedures

As of June 30, 2026, our management, with participation of our principal executive officer and principal financial officer, performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a – 15(e) under the Exchange Act). In prior reporting periods, two material weaknesses in internal controls over financial reporting (described below) were identified and have not yet been remediated. Our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2026.

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

### Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act). Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States.

### Previously Reported Material Weaknesses

As previously disclosed, a material weakness was identified related to management’s assessment of long-lived assets for impairment. This material weakness resulted in an adjustment of $1.5 million to the Company’s audited financial statements for the year ended December 31, 2025. Additionally, this material weakness could result in misstatements of long-lived assets (property, plant and equipment) or disclosures that would result in a material misstatement to the annual or condensed financial statements that would not be prevented or detected.

As previously disclosed, Management identified a material weakness in the level of precision of the Company’s review control over the application of technical accounting evaluation related to complex warrant instruments and financing transactions.

The material weakness resulted in the following accounting outcomes: (1) the previously identified misclassification of certain warrants as equity rather than liabilities under ASC 815-40, *Derivatives and Hedging*, and (2) the subsequently identified failure to recognize certain warrants as participating securities under ASC 260, *Earnings Per Share*, resulting in the incorrect application of the two-class method.

The ASC 260 error resulted in a material misstatement of net income attributable to common stockholders and basic earnings per share for the three months ended March 31, 2026 and the restatement of the Company’s previously issued unaudited condensed financial statements for that period. The error did not affect total net income, revenues, operating expenses, cash flows, assets, liabilities or stockholders’ equity.

Because of these material weaknesses identified in previous reporting periods but not yet remediated, management concluded that the Company did not maintain effective internal control over financial reporting as of June 30, 2026.

### Remediation Plans for Material Weaknesses in Internal Controls over Financial Reporting

We are committed to establishing and maintaining a strong internal control environment. In response to the identified material weakness as described above, the Company’s Board of Directors and its Audit Committee are conducting an internal investigation to determine the root cause of the material weaknesses, with advice from outside advisors. Upon conclusion of this investigation, they will work with management to evaluate internal controls over financial reporting based on criteria set forth in “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Remediation plans will include obtaining a current appraisal at least once a year in preparation for the Annual Report, and more often if the market appears to be weakening or other triggers for an indication of impairment have occurred. Management intends to establish procedures to ensure proper monitoring of indicators of impairment such as a significant market price decrease, adverse changes in physical condition/usage, legal factors, or current-period operating losses, for each reporting period. For complex transactions, management resolved to allow for more time and resources to determine proper accounting and disclosure of these transactions. Management intends to enhance the precision of the Company’s technical accounting review control by establishing formal consultation and escalation criteria for complex warrant and financing arrangements, including required legal interpretation where contractual provisions may affect the accounting conclusion. Require documented evaluation of all relevant contractual terms and evidence that identified accounting and legal considerations were fully resolved before the accounting treatment is finalized.

### Inherent Limitations of Internal Controls

While we strive to create a stronger control environment, we recognize that it is impossible for our internal controls over financial reporting to prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. While we are committed to continuously improve and strengthen our control environment, over time, our internal controls over financial reporting may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Projections of any evaluation of effectiveness to future periods are subject to the risk that internal controls over financial reporting may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

### Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act during the three months ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

## Risk factors

As filed, 545 characters.

There have been no material changes to the risk factors previously disclosed by us in our Annual Report. The risk factors included our Annual Report continue to apply to us and describe risks and uncertainties that could cause actual results to differ materially from the results expressed or implied by the forward-looking statements contained in this Quarterly Report. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business, financial condition and results of operations.
