Bluejay Diagnostics, Inc.

Notes to the Condensed Consolidated Financial Statements

(Unaudited)

1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Business

Bluejay Diagnostics, Inc. (“Bluejay” and/or the “Company”) is a medical diagnostics company focused on improving patient outcomes in critical care settings, with a focus on sepsis. The Company is working on developing rapid, near-patient tests using whole blood on its Symphony technology platform (“Symphony”), which consists of an analyzer and single-use protein detection cartridges. The Company does not yet have regulatory clearance for Symphony, and it will need to receive regulatory authorization from the U.S. Food and Drug Administration (the “FDA”) before Symphony can be marketed as a diagnostic product in the United States. The Company has completed the pre-clinical development of the Symphony analyzer. During 2025, the Company transferred the intellectual property underlying the production of the Symphony cartridges from the original developer and outside supplier, Toray Industries, to a contract manufacturing facility with FDA certification run by Sanyoseiko. The Company has successfully resolved the technical issues related to the Symphony cartridge manufacturing process in collaboration with SanyoSeiko and is now progressing toward analytical and clinical validation to support regulatory submission. To achieve its plan, the Company expects to need to raise at least $20 million of further capital by the end of the 2027 fiscal year, which the Company hopes to do in various tranches.

The Company’s Symphony platform is a combination of Bluejay’s intellectual property (“IP”) and exclusively licensed and patented IP on the Symphony technology that the Company believes if cleared, authorized, or approved by the FDA, could provide a solution to a significant market need in the United States. The Symphony device candidate is designed to produce laboratory-quality results in approximately 20 minutes in critical care settings, including Intensive Care Units (“ICUs”) and Emergency Rooms (“ERs”), where rapid and reliable results are required.

The Company’s first product candidate, the Symphony IL-6 test, is an immunoassay for the measurement of interleukin-6 (IL-6) to be used for the monitoring of disease progression in critical care settings. The Company is currently focused on pursuing the Symphony IL-6 test in the context of sepsis. IL-6 is a clinically established inflammatory biomarker, and is considered a ‘first-responder,’ for assessment of severity of infection and inflammation across many disease indications, including sepsis. A current challenge of healthcare professionals is the excessive time and cost associated with determining a patient’s level of severity at triage and the Company believes that its Symphony IL-6 test, if ultimately successful and approved, could have the ability to consistently monitor this critical care biomarker with rapid results.

If the Company succeeds with the foregoing plan, in the future it hopes to develop additional tests for Symphony, including tests for myocardial infarction and congestive heart failure (cardiac biomarkers hsTNT and NT pro-BNP) as well as other tests using the Symphony platform.

The Company was incorporated under the laws of Delaware on March 20, 2015. Its headquarters are located in Acton, Massachusetts.

On June 4, 2021, the Company formed Bluejay Spinco, LLC, a wholly-owned subsidiary of the Company, for purposes of further development of the Company’s ALLEREYE diagnostic test. ALLEREYE is a point-of-care device offering healthcare providers a solution for diagnosing Allergic Conjunctivitis. The Company currently is not actively pursuing development of the ALLEREYE diagnostic test. On March 3, 2026, the Company completed the dissolution of its wholly owned subsidiary Bluejay Spinco, LLC.

FDA Regulatory Strategy

The design, development, manufacture, testing and sale of the Company’s products in the U.S. are subject to regulation by numerous governmental authorities, principally the FDA, and corresponding state and local regulatory agencies. Generally, the products we develop must be cleared by the FDA before they are marketed in the United States. Before and after approval, authorization, or clearance in the United States, our products are subject to extensive regulation by the FDA, as well as by other regulatory bodies. FDA regulations govern, among other things, the development, testing, manufacturing, labeling, safety, storage, recordkeeping, market clearance, authorization or approval, labeling and promotion, import and export, marketing and sales, and distribution of medical devices.

The Company’s current regulatory strategy is designed to support commercialization of Symphony in the United States if and when the Company receives marketing authorization from the FDA. In May 2023, the Company submitted a pre-submission application to the FDA presenting study designs to validate Symphony IL-6 for use with hospitalized sepsis patients. The Company participated in a pre-submission meeting with the FDA in August 2023, and at the meeting the FDA provided feedback on the study design, determined that the submission of a 510(k) is the appropriate premarket submission pathway, and requested that certain data be provided in the 510(k). Based on this feedback, the Company determined to proceed on this basis, which considers the FDA’s feedback.

In the second quarter of 2024, the Company completed a multicenter SYmphony IL-6 MONitoring Sepsis (“SYMON”) clinical study investigating the role of interleukin-6 (IL-6) in patients diagnosed with sepsis and septic shock. This prospective study assessed the performance of IL-6 upon initial presentation to the intensive care unit (ICU). A primary endpoint of the SYMON-I pilot clinical study (registered clinical trial number NCT06181604) suggested that IL-6 levels within 24 hours of sepsis or septic shock diagnosis and admission to the ICU may predict patient mortality out to 28 days. Furthermore, a secondary endpoint of the SYMON-I study suggested that IL-6 levels within 24 hours of sepsis or septic shock diagnosis and admission to the ICU is a predictor of patient mortality during their hospitalization. Other secondary endpoints suggested that lactate and Sequential Organ Failure Assessment (SOFA), standard clinical tests used for sepsis and septic shock patients, were not predictors of patient mortality out to 28 days. We believe that the findings underscore the potential importance of IL-6 as a predictor and provide new insights into the potential pathways for improving sepsis outcomes.

Using the data analysis from the SYMON-I pilot clinical study, the Company initiated the SYMON-II pivotal clinical study in the third quarter of 2024. The SYMON II clinical study has three components: (1) collection, freezing, and biobanking of patient samples, (2) measuring IL-6 concentrations in the biobanked samples near the end of patient enrollment or after the patient enrollment has completed, and (3) analysis of the IL-6 data with the patient outcomes to see if the established IL-6 cutoff value has been validated for 28-day all-cause mortality. Patient enrollment started during the fourth quarter of 2024. As of May 5, 2026, the Company has enrolled approximately 680 hospital patients among a target of 750 patients, and it has collected, frozen and biobanked blood samples from the enrolled patients, while also obtaining all related patient data regarding their disease progression and outcomes. The Company expects to complete patient enrollment in the study in the summer of 2026. The Company’s goal is to use the Symphony IL-6 test to complete the testing in the SYMON-II clinical trial. The Company is not yet testing the samples because it is simultaneously working with Sanyoseiko to manufacture the cartridges that will be used in the test, and these cartridges are still being manufactured and verified to ensure that they meet FDA requirements for submission and commercial production. The Company’s goal is to produce and verify these cartridges during 2026.

If the Company is able to complete the SYMON-II clinical study and the results are positive, the Company intends to use the data generated from SYMON-II to support a 510(k) application to the FDA. This application is currently expected to be based on the following intended use: “Symphony IL-6 is intended for use to determine the IL-6 concentration as an aid in assessing the cumulative 28-day risk of all-cause mortality in conjunction with other laboratory findings and clinical assessments for patients diagnosed with sepsis or septic shock in the ICU.” The Company also plans to present the SYMON-I and SYMON-II results at future national scientific meetings and publish them in peer-reviewed journals, subject to future completion of the SYMON-II study and the results being positive. Subject to achieving needed funding and successfully achieving commercial grade manufacturing with its cartridges, the Company’s plan is to begin testing of samples it is collecting as part of the SYMON-II clinical trial by the end of 2026, with a goal of being in position to submit a 510(k) regulatory application to the FDA during the first half of 2027, and an objective of achieving FDA clearance thereafter.

The Company’s ability to engage in and complete the activities needed for an FDA submission will be contingent upon raising sufficient capital, remaining a going concern, and producing product capable of meeting analytical validation and clinical validation.

Product Manufacturing

The Company plans to manufacture its analyzers and cartridges through Sanyoseiko Co. Ltd. (“Sanyoseiko”), as a contract manufacturing organization (“CMO”), and the Company has entered into master supply and master service agreements with Sanyoseiko governing these matters. Pursuant to statements of work that the Company has begun providing to Sanyoseiko under these agreements, Sanyoseiko will provide end-to-end support for the Symphony platform, including supporting the manufacturing process for analyzers and cartridges (with hardware, software, and design updates), managing raw material sourcing and vendor compliance, and serving as the Company’s contract manufacturing organization for analyzers, cartridges, and related components. In this capacity, Sanyoseiko will oversee fulfillment, kit assembly, labeling, packaging, shipping, and quality control of manufactured products, while also providing regulatory and quality management support, and equipment storage and maintenance.

Sanyoseiko had been selected as the Company’s CMO due to their core competencies in manufacturing and quality systems recognized by the FDA. Sanyoseiko’s facilities are located in Japan. The Company currently licenses the technology for the Symphony cartridges from Toray Industries, Inc. (“Toray”). The Company’s license grants it exclusive global marketing rights, with the exception of Japan. The Company holds the rights to manufacture the analyzers and the cartridges.

To further de-risk manufacturing and support scale-up, the Company has executed a manufacturing partnership with Argonaut Manufacturing Services, an FDA-registered and ISO-certified IVD manufacturer.

Risks and Uncertainties

As noted above, the Company will be reliant upon its CMO, Sanyoseiko to provide analyzers and cartridges, in sufficient quantity and quality to complete the validations for its FDA application. The Company’s FDA application submission could be delayed if the Company encounters any material supply interruptions. In addition, there can be no assurance that the Company will be able to obtain necessary regulatory authorization for the marketing of the Symphony in the United States or elsewhere. There also can be no assurance that the Company will successfully complete any clinical evaluations necessary to receive regulatory clearances, or that the clinical study will demonstrate sufficient safety and effectiveness of the Symphony IL-6 test. The failure to adequately demonstrate the clinical performance of the Symphony IL-6 test could delay or prevent regulatory clearance, which could prevent or result in delays to market launch and could materially harm the Company’s business.

In addition to the FDA regulatory strategy risks and uncertainties, the Company is subject to a number of risks similar to other companies in its industry, including rapid technological change, competition from larger biotechnology companies and dependence on key personnel. Additional risk and uncertainties regarding the Company are described in “Part I – Item 1A. Risk Factors” of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and in in “Part II – Item 1A Risk Factors” of this Quarterly Report on Form 10-Q.

Reverse Stock Splits and Increase to Authorized Capital

On January 29, 2026, the Company effected a reverse stock split of its shares of common stock at a ratio of 1-for-4 (the “January 2026 Reverse Stock Split”). All of the Company’s historical share and per share information related to issued and outstanding common stock and outstanding options and warrants exercisable for common stock in these financial statements have been adjusted, on a retroactive basis, to reflect these reverse stock splits.

At the Company’s annual meeting of stockholders on June 18, 2025, the Company’s stockholders provided the Company’s board of directors with authority to implement the January 2026 Reverse Stock Split, as well as an additional reverse stock split at a ratio of up to 1-for-20 (the “Additional Reverse Stock Split”). The Additional Reverse Stock Split may not be implemented if it would reduce the number of publicly held shares of the Company’s common stock to less than 500,000. The Board’s authority to implement the Additional Reverse Stock expires on June 18, 2026. The Company has included in its proxy statement for its upcoming annual meeting of stockholders on June 9, 2026 a further proposal to provide the Company’s board of directors authority to implement an additional reverse stock split, at a ratio of up to 1-for-20 and on terms otherwise substantially the same as the Additional Reverse Stock Split, during the period from the date of such meeting until June 9, 2027.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in conformity with generally accepted accounting principles in the United States (“US GAAP”) consistent with those applied in, and should be read in conjunction with, the Company’s audited financial statements and related footnotes for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K. The unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2026, its results of operations and cash flows for the three months ended March 31, 2026 and 2025, in accordance with US GAAP. The unaudited condensed consolidated financial statements do not include all of the information and footnotes required by US GAAP for complete financial statements, as allowed by the relevant U.S. Securities and Exchange Commission (“SEC”) rules and regulations; however, the Company believes that its disclosures are adequate to ensure that the information presented is not misleading. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation.

The results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026, or any other interim period within this fiscal year.

Going Concern

The accompanying unaudited condensed consolidated financial statements for the three months ended March 31, 2026 and 2025 were prepared under the assumption that the Company will continue as a going concern, which contemplates that the Company will be able to realize assets and discharge liabilities in the normal course of business.

The Company had cash and cash equivalents of $3,684,457 and current liabilities of $1,413,919 as of March 31, 2026. The Company has incurred net losses and negative cash flows from operations since its inception and has an accumulated deficit of $43,436,508 as of March 31, 2026. The Company expects that its net cash used in operating activities will continue to be negative over at least the next several years as it attempts to produce product capable of meeting analytical validation and clinical validation and conducts clinical trial work and, if such production and trials are successful, prepare an FDA submission. These financial results and financial position, and the Company’s expected forward-looking outlook of significant negative cash flow in the future, raise substantial doubt with respect to its ability to continue as a going concern. The Company expects that it will not be in position to submit a 510(k) regulatory application to the FDA for Symphony until at least 2027, if it is even able to generate sufficient clinical trial results to support such a submission. If the Company fails to obtain sufficient future financing, its clinical trials and targeted FDA submission timeline could be delayed, and it could be forced to abandon such activities entirely and cease operations, with the possible loss of such properties or assets. If the Company is unable to obtain additional financing as it continues to generate negative cash flow, its board of directors could determine to cause the Company to undertake a process of liquidation under Chapter 7 of applicable U.S. bankruptcy laws, or otherwise seek other protection under such laws. In such event, holders of shares of the Company’s common stock could recoup little, if any, value in such process. The Company currently estimates cash resources will be sufficient to fund its operations through the third quarter of 2026.

These accompanying financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

2.SIGNIFICANT ACCOUNTING POLICIES

During the three months ended March 31, 2026, there were no changes to the significant accounting policies as described in the 2025 Audited Financial Statements.

Use of estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in these consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. The Company evaluates its estimates and assumptions as facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from these estimates and assumptions, and those differences could be material to the consolidated financial statements.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in the Financial Accounting Standards Board, or the FASB, ASC, 480, Distinguishing Liabilities from Equity, or ASC 480, and ASC 815, Derivatives and Hedging, or ASC 815. The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. Finally, the Company determines if the warrants meet the definition of a derivative based on their contractual terms. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and at each balance sheet date thereafter. The Company uses the Black Scholes option pricing model to determine fair value. Changes in the estimated fair value of liability-classified warrants are recognized as a non-cash gain or loss on the consolidated statements of operations. The Company also evaluates if changes in contractual terms or other considerations would result in the reclassification of outstanding warrants from liabilities to stockholders’ equity (or vice versa).

Segment Reporting

The Company follows the guidance in ASC 280, Segment Reporting. Management has determined that the Company operates asone operating and reportable segment, asthe Chief Executive Officer, who serves as the Chief Operating Decision Maker, evaluates performance of the operating segment and allocates resources based on amounts as reported on the consolidated statements of operations and cash flows. Segment expenses are presented on the Company’s consolidated statements of operations. The operating segment assets are reported on the consolidated balance sheets as total assets. The Company’s operations consist solely of the development of its Symphony diagnostic platform, a near-patient diagnostic platform designed to provide rapid results for critical care settings, and no discrete financial information is produced for separate business components. Accordingly, the consolidated financial statements represent the Company’s single reportable segment.

Net Loss per Share

Basic net loss per share to common stockholders is computed by dividing the net loss applicable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding for the period determined using the treasury stock and if-converted methods. Dilutive common stock equivalents are comprised of options outstanding under the Company’s stock option plan, restricted stock units, and warrants. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive.

Potentially dilutive securities not included in the calculation of diluted net loss per share, because to do so would be anti-dilutive, are as follows (in common stock equivalent shares):

Recently Issued Accounting Standards

Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU 2024-03, Reporting Comprehensive Income-Expense Disaggregation Disclosures. This change requires disaggregated disclosures of certain categories of expenses that are included in expense line items on the face of the income statement. The disclosures are required on an annual and interim basis. The guidance also requires the total amount of selling expenses to be disclosed and, on an annual basis, the definition of selling expenses. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. This new guidance will result in increased disclosures in the notes to the financial statements.

3. LICENSE AND SUPPLY AGREEMENT WITH TORAY INDUSTRIES

The Company depends on Toray’s intellectual property for the Symphony cartridges upon which the Symphony platform relies. On October 6, 2020, the Company entered into a License and Supply Agreement (the “License Agreement”) with Toray, providing the Company with an exclusive global license (excluding Japan) to use Toray’s patents and know-how related to the Symphony detection cartridges for manufacturing, marketing and sale of the products (as defined in the License Agreement). In exchange for the license, the Company committed to make two payments of $120,000 each to Toray, both of which were made in 2021. In addition, following the first sale of the cartridges after regulatory clearance, the Company is obligated to make royalty payments to Toray based on the net sales of the cartridges for the period that any underlying patents exist or ten years after the first sale. Following the first sale after obtaining regulatory clearance, the Company will make minimum annual royalty payments of $60,000 for the first year and $100,000 for each year thereafter, which shall be creditable against any royalties owed to Toray in such calendar year.

On October 23, 2023, the Company and Toray entered into an Amended and Restated License Agreement (the “New Toray License Agreement”) and a Master Supply Agreement (the “New Toray Supply Agreement”). Under the New Toray License Agreement, the Company continues to license from Toray intellectual property rights needed to manufacture single-use test cartridges, and the Company has received the right to sublicense certain Toray intellectual property to Sanyoseiko in connection with Sanyoseiko’s ongoing agreement with the Company to manufacture the Company’s Symphony analyzers and cartridges (including in connection with the Company’s clinical trials). In addition, the New Toray License Agreement provided for the transfer of certain technology related to the cartridges to Sanyoseiko. The royalty payment percentage payable by the Company to Toray was reduced under the New Toray License Agreement from 15% to 7.5% (or less in certain circumstances) of net sales of certain cartridges for a term of 10 years. A 50% reduction in the royalty rate applies upon expiry of applicable Toray patents on a product-by-product and country-by-country basis. The New Toray License Agreement contemplates that applicable royalty payment obligations from the Company to Toray for other products will be determined separately by the parties in the future.

On July 23, 2025, the Company entered into an amendment (the “Amendment”) to the New Toray License Agreement and the New Toray Supply Agreement with Toray. The Amendment provided that the deadline under the New Toray License Agreement for the Company to establish an alternative manufacturing site for the Company’s Symphony cartridges would be extended from October 23, 2025 to October 23, 2026, and the Company has agreed to use its best efforts to establish the site by such date. The Amendment confirms that Toray has provided to the Company all applicable know-how required under the New Toray License Agreement and is not under any further obligation to provide know-how or technical assistance to the Company. Pursuant to the Amendment, the Company paid $71,212 to Toray for a final supply of certain chip components prior to the expiration of the New Toray Supply Agreement, which occurred on October 23, 2025. There were no sales of or revenues from the cartridges during the quarters ended March 31, 2026 and 2025.

The Company has completed cartridge manufacturing process redevelopment through Sanyoseiko, a third-party contractor who is managing such manufacturing process. The Company is planning to proceed to verification and validation testing and commercial manufacturing. At March 31, 2026 and 2025, there were no amounts accrued related to the New Toray License Agreement or the License Agreement.

4. FINANCINGS

On March 14, 2026, the “Company entered into a securities purchase agreement pursuant to which the Company issued and sold to the purchasers named therein an aggregate of 62,500 shares of the Company’s common stock at a price of $2.00 per share The transaction closed on March 17, 2026 for aggregate gross proceeds to the Company of $125,000.

Each of the purchasers represented that it is an “accredited investor” within the meaning of Rule 501 of Regulation D, was acquiring the shares for his or her own account, and had no direct or indirect arrangement or understanding with any other persons to distribute or regarding the distribution of such shares. The shares were offered and sold without any general solicitation by the Company or its representatives. The Company has not agreed to provide registration rights with respect to any of the shares.

On October 9, 2025, the Company entered into a securities purchase agreement with two institutional investors pursuant to which the Company sold in a private placement (i) an aggregate of 43,750 shares of common stock and prefunded warrants to purchase up to 518,750 shares of common stock (the “October 2025 Prefunded Warrants”), and (ii) Series F warrants (the “Series F Warrants”) to purchase up to 1,125,000 shares of common stock. The combined price of the securities sold in the private placement was $8.00 per share of common stock (or prefunded warrant in lieu thereof, in which case such price was reduced by $0.0004) and accompanying Series F Warrants to acquire two shares of common stock. The October 2025 Prefunded Warrants were exercisable for shares of common stock at an exercise price of $0.0004 per share, are immediately exercisable and expire once exercised in full. As of March 31, 2026, all of the October 2025 Prefunded Warrants were exercised in full. The Series F Warrants are exercisable for shares of common stock at an exercise price of $7.00 per share, are immediately exercisable and expire five andone-half years from the date of issuance.

The transaction closed on October 10, 2025. The gross proceeds to the Company from the sale of the securities sold in the private placement were approximately $4.5 million. The Company incurred total offering costs of $787,755, including a 8% financial advisory fee to Rodman and Renshaw LLC (“Rodman”), the placement agent, of approximately $360,000. Under the terms of the Company’s engagement letter with Rodman, the Company issued Rodman’s designees warrants to purchase up to 45,000 of common stock at an exercise price of $10.00 per share, which expire 5.5 years from the date of issuance (the “October 2025 Placement Agent Warrants”).

In connection with this private placement, the Company filed a registration statement on Form S-3, which became effective on November 26, 2025 to register 1,732,500 shares of common stock (including any shares of common stock issued in the future pursuant to the Series F Warrants or October 2025 Placement Agent Warrants) for resale in public markets.

Holders of the warrants will not have the right to exercise any portion of such warrants if such holder, together with its affiliates, would beneficially own in excess of 4.99% or 9.99% (at the initial election of the holder) of the number of shares of the Company’s common stock outstanding immediately after giving effect to such exercise, provided that a holder may increase or decrease such beneficial ownership limitation up to, and no higher than,9.99%, by giving 61 calendar days’ notice to the Company.

April 2025 Private Placement

On April 7, 2025, the Company entered into inducement letter agreements with certain existing holders of the Company’s Class C warrants (the “Class C Warrants”), pursuant to which such holders agreed to purchase an aggregate of 271,277 shares of the Company’s common stock (or, to the extent the applicable holder would have exceeded a specified beneficial ownership limitation, prefunding the future exercise of such warrants, other than a remaining $0.0004 per share exercise price). The Class C Warrants were originally issued on June 28, 2024 for an exercise price of $392.00 per share and were subsequently reduced to $65.20 per share pursuant to stockholder approval on August 21, 2024. Pursuant to the inducement letter agreements, the applicable holders agreed to exercise their Series C Warrants at a reduced exercise price of $13.68 per share, and to purchase an equivalent number of new Class E warrants (the “Class E Warrants”) for an additional $0.50 per share. The Class E Warrants have an exercise price of $13.68 per share and expire on April 8, 2030.

The transaction closed on April 8, 2025. The exercise of the Class C Warrants resulted in the Company issuing 170,551 shares of common stock at closing pursuant to the inducement letters, and the exercise price of 100,726 of the Class C Warrants being amended to 0.0004 per share. As of December 31, 2025, all such reduced exercise price Class C Warrants had been exercised.

The gross proceeds to the Company from the exercise of the Class C Warrants and the sale of the new Class E Warrants were $3,846,707. The Company incurred total cash offering costs of $464,670, including a 10% financial advisory fee to Aegis Capital Corp. of $384,670.

The modification of the terms or conditions of the Class C Warrants in this transaction is treated as an exchange of the original instrument for a new instrument. Using the Black Scholes option pricing model, the fair value of the Series C Warrants immediately prior to the inducement transaction was $479,299 and immediately after the inducement transaction was $1,590,930. In addition, Series E Warrants with a fair value of $1,730,652 were provided as part of the inducement transaction for a purchase price of $135,638. The Company recorded additional equity issuance costs of $2,706,645 related to the modification of the Series C Warrants and issuance of Series E Warrants related to the inducement transaction. As this equity issuance cost was a non-cash transaction, the Company recorded an increase to additional paid-in capital to offset the expense.
