Item 1.       Business

We are a contract development and manufacturing organization (“CDMO”) that provides a comprehensive range of biologics manufacturing services from process development to Current Good Manufacturing Practices (“CGMP”) clinical and commercial manufacturing of biologics for the biotechnology and biopharmaceutical industries. Scorpius pairs CGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support the production of cell- and gene-based therapies as well as large molecule biologics. Our services include clinical and commercial drug substance manufacturing, release and stability testing and variety of process development services, including upstream and downstream development and optimization, analytical method development, as well as cell line development, testing and characterization. Our San Antonio, TX facility commenced operations in September 2022.

During the past year, our priorities had shifted to biomanufacturing capabilities resulting in a refocusing of our resources and efforts towards biomanufacturing and away from our clinical-stage oncology assets including HS-110 and PTX-35, and biodefense efforts. We also intend to continue minimal discovery efforts of our subsidiary, Skunkworx, if we have sufficient resources.

Recent Developments

Sales Agreement

On December 8, 2023, we entered into a Sales Agreement (the “2023 ATM Sales Agreement”) with A.G.P./Alliance Global Partners (the “Sales Agent” or “A.G.P.”) providing for the sale by us of shares of our common stock, from time to time, through or to A.G.P., as sales agent or principal, with certain limitations on the amount of common stock that may be offered and sold by us as set forth in the Sales Agreement (the “Offering”). Prior to entering into the Sales Agreement with A.G.P., effective December 8, 2023, we terminated the Amended and Restated At Market Issuance Sales Agreement, dated August 24, 2020, by and among us, B. Riley Securities, Inc. (“B. Riley”) and Cantor Fitzgerald & Co. (“Cantor”), as amended by Amendment No. 1 thereto, dated December 10, 2020 (the “2020 ATM Sales Agreement”), pursuant to which we agreed to offer and sell, from time to time, at our option, shares of common Stock through B. Riley and/or Cantor in an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act. Under the 2023 ATM Sales Agreement, we issued and sold an aggregate of 137,571 shares of common stock and received net proceeds of $0.05 million in December 2023. We issued and sold an aggregate of 19,500 shares of common stock and received net proceeds of $0.01 million in January 2024. Under the 2020 ATM Sales Agreement, for the year ended December 31, 2021, we issued and sold an aggregate of 2,106,027 shares of common stock and received net proceeds of approximately $25.6 million. For the year ended December 31, 2022, we did not issue any shares of common stock under the 2020 ATM Sales Agreement. There were no penalties associated with the termination of the 2020 ATM Sales Agreement. Due to the late filing of this Annual Report, until May 2025 we will not be eligible to make sales of shares of common stock under the 2023 ATM Sales Agreement.

Patent Rights Agreement

On January 29, 2024, we entered into a Patent Rights Sale and Assignment Agreement with Kopfkino IP, LLC (“Patent Agreement”). Pursuant to the Patent Agreement, in exchange for $1,000,000, we assigned our right, title and interest in and under the exclusive license agreement it entered into with Shattuck Labs, Inc. (“Shattuck”) in 2016, including our rights to certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us.

Convertible Note

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023, with Elusys Holdings, Inc. (“Elusys Holdings”), described in more detail below in the section entitled

4

“The Divestiture of Elusys Therapeutics, Inc.” in this Item 1, Elusys Holdings purchased from us a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys’ Holdings election and obtaining stockholder approval of the issuance of shares of our common stock upon such conversion. The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of our common stock at the option of Elusys only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note.

Certificate of Amendment

On February 5, 2024, we filed a Certificate of Amendment (the “Certificate of Amendment”) to the Third Amended and Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to effect, as of February 6, 2024, a change of our name to Scorpius Holdings, Inc. (the “Name Change”). In connection with the Name Change, our common stock began trading on the NYSE American LLC under the new ticker symbol “SCPX,” effective as of the opening of trading hours on February 6, 2024.

OUR BIOMANUFACTURING, PROCESS DEVELOPMENT, AND BIOMANUFACTURING CAPABILITIES: SCORPIUS BIOMANUFACTURING, INC.

Manufacturing

Scorpius (formerly known as Scorpion Biological Services, Inc.) provides process development and biomanufacturing services to support the biomanufacturing needs of its customers. Scorpius couples CGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support cell- and gene-based therapies as well as large molecule biologics using American-made equipment, reagents, and materials. We anticipate the prioritization of Scorpius on American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make us competitive for U.S. government contracts and biodefense assets. We anticipate this will successfully support our expansion within the growing CDMO market.

We commenced operations of the leased San Antonio facility in September 2022.

We intend to meet our financing needs for the operations of the facility through multiple alternatives, including, but not limited to, cash on hand, grant funding and incentives, additional equity financings, debt financings, equipment sale leaseback, and/or funding from partnerships or collaborations, and potential revenue, if any, from our planned development and manufacturing facility.

We plan to manufacture CGMP pharmaceutical-grade products for our customers in our San Antonio facility. Scorpius has multiple biotechnology, pharmaceutical, and university customers from which it has generated revenue to date. The deposits from these customers are in deferred revenue and will be converted to revenue once we meet our performance obligations for these contracts. The process for manufacturing generally uses commercially available raw materials from multiple suppliers, and in some instances, from a single source supplier. We rely on third parties to supply most of the necessary raw materials and supplies for the products we manufacture on behalf of our customers and our inability to obtain such raw materials or supplies may adversely impact our business, financial condition, and results of operations. See “Risk Factors—Risks Related to Our Business” for additional discussion of raw materials supplied by third party vendors for the products we manufacture for our customers.

Our Competitive Strengths

We believe that we are well positioned to address the market for biopharmaceutical manufacturing derived from mammalian and microbial cell culture, due to the following factors:

◾ Expertise in Mammalian and Microbial Cell Culture Manufacturing: We believe that continued consolidation in the CDMO industry has resulted in a limited number of qualified, agile and independent CDMOs with mammalian and microbial cell culture-based biologics development and manufacturing capabilities. We believe we are well

5

positioned in the industry, given our expertise in mammalian and microbial cell culture for biologics manufacturing.

◾ Broad Spectrum of Services to Support Customers from Early Stage Development to Commercial: We provide fully integrated and customized biomanufacturing services that support our customers from the early preclinical stage to commercial launch and supply. Our process development, CGMP drug substance biomanufacturing, project management, quality systems and quality control are all supported by modern facilities designed to meet customer needs for clinical scale or small scale commercial production. We differentiate our capabilities through several key criteria: (i) we employ a customer-centric approach and collaborate with our customers to tailor customized development and manufacturing services; (ii) our agile manufacturing and development capabilities allow for rapid responses to shifting production and (iii) our single-use bioreactors contribute to enhanced manufacturing efficiency for our customers and reduce our capital spending needs.

◾ Modern and Optimized Infrastructure: With our San Antonio facility we continue to position our business to capitalize on increasing demand in the biologics manufacturing industry for modular cleanroom space, onsite analytical and process development laboratories and single-use bioreactors. These developments have driven demand among pharmaceutical companies for facilities that can develop and produce pilot scale batches in process development using a process train that matches the single-use bioreactors in CGMP production. With single-use bioreactors, our San Antonio facility is designed to provide our customers with the desired efficiency, flexibility.

Our Growth Strategy

We believe we have a significant opportunity to continue to drive organic growth by leveraging our strengths, broadening our capabilities, increasing our capacity and improving our market visibility through the following strategies:

◾ Diversify Customer Base: We have diversified and expanded our customer base and have developed marketing and sales strategies designed to further diversify our customer base and drive new customer acquisitions, while also continuing to leverage our existing relationships to support new programs with our existing customers.

◾ Expand Service Offerings: We have invested in strategic opportunities to expand our service offerings. During fiscal 2023, we expanded our CDMO service offering to include enhanced microbial and mammalian development and manufacturing services.

◾ Expand Process Development Capabilities: We have expanded our process development capabilities in order to make our operations more attractive to emerging biotechnology and pharmaceutical companies. We will continue to explore the addition of capabilities and services that bring value to our customers, enhancing their processing design, speeding their time to market and supporting these activities with state-of-the-art analytics.

◾ Increase Operating Margins: We believe we have the opportunity to drive operating margin expansion by utilizing our available capacity, and implementing continuous process efficiencies. We believe increased facility capacity utilization resulting from the growth strategies described herein will improve operating margins.

The key elements of our strategy are:

◾ Maximize commercial opportunities for Scorpius Biomanufacturing, Inc: We launched Scorpius in September 2022 as a CDMO focused on developing bioanalytic, process development, and biomanufacturing capabilities to support our clinical and commercial pipeline. We are opportunistic in offering biomanufacturing capacity to third parties as a fee-for-service model and believe our prioritization of American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make the organization competitive for U.S. government contracts and biodefense assets.

◾ Enhance our partnering efforts: We are continually exploring partnerships for licensing and other collaborative relationships and remain opportunistic in seeking strategic partnerships that maximize our economic potential and align with our objective to become a market leader in the development and commercialization of innovative medical countermeasures.

◾ Manage our business with efficiency and discipline: We believe we have efficiently utilized our capital and human resources to develop and build out our CDMO capabilities.

The Divestiture of Elusys Therapeutics, Inc.

On December 27, 2023, pursuant to that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023 (the “Agreement”), that we entered into with Elusys Holdings, Inc. (“Elusys Holdings”), a company controlled by our Chairman, Chief Executive Officer and President, Jeffrey Wolf, we completed the sale to Elusys Holdings of: (i) all of the issued and outstanding equity interests in Elusys Therapeutics, Inc., our wholly owned subsidiary (“Elusys Therapeutics”), and (ii) the exclusive right to use the name “NightHawk” and ownership of any and all trademark, goodwill and other rights in connection with such name, which right and ownership will commence at a later date to be agreed upon by the parties (collectively, the “Purchased Assets”) (such transaction, the “Divestiture Transaction”).

Pursuant to the Agreement, at the December 27, 2023 closing of the Divestiture Transaction (the “Divestiture Closing”), Elusys Holdings assumed certain specified liabilities and manufacturing commitments relating to Elusys Therapeutics’ business, which at the time of the Divestiture were estimated at $51.4 million. The assumed liabilities and manufacturing commitments include all amounts owed to the former owners of Elusys Therapeutics under that certain Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) by and among us, Heat Acquisition Sub 1, Inc., Elusys Therapeutics and Fortis Advisors LLC, in its capacity as “Stockholders’ Representative,” which provides that we will remain liable if Elusys Holdings fails to satisfy its obligations to pay merger consideration under the Merger Agreement. In addition, from and after the Divestiture Closing, Elusys Holdings assumed all operating costs of Elusys Therapeutics, including the costs incurred after the closing related to Elusys Therapeutics employees, consultants, and regulatory and research costs. Mr. Wolf and William Ostrander, our Chief Financial Officer, will continue to serve in their current positions with us and also continue to serve as the Chief Executive Officer and Chief Financial Officer, respectively, of Elusys Holdings.

Pursuant to the Agreement, Elusys Holdings was obligated to pay us $500,000 on December 11, 2023, which payment was timely completed. Elusys Holdings  is further obligated to pay to us on an annual basis a royalty fee equal to 3% of gross revenue received by Elusys Holdings or any of its affiliates or their respective successors or licensees from all sales of the anthrax antitoxin known as ANTHIM® during the period commencing on January 1, 2024 and ending on June 30, 2031; provided that, if as of December 31, 2028, we have not received an aggregate of $5,000,000 in such royalty fees, Elusys Holdings  will be obligated to pay to us  no later than March 1, 2029 a cash payment equal to the difference between the aggregate amount of such royalty fees received by us  and $5,000,000. As of December 31, 2023, the fair value of this contingent earn-out receivable, related party is $1.7 million. The fair value calculation used a discounted cash flow analysis over a period of five years (through December 31, 2028) that utilized a discount rate of 15.0%, risk-free rates ranging between 4.2% and 5.4%. The contingent earn out royalty payments were based on five year probability, adjusted revenue projections with probability rates between 85% and 97.5%.

Elusys Holdings also, as a post-closing covenant, on January 26, 2024 purchased from us a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys Holdings’ election and obtaining stockholder approval of the issuance of shares of our common stock upon such conversion. As of December 31, 2023, the fair value of this contingent consideration receivable, related party is $0.3 million. The Note bears interest at a rate of 1% per annum, mature on the one-year anniversary of its issuance and convert into shares of our common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is equal to $0.39109 (which was 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023). Based upon a conversion price of $0.39109, which is 110% of the VWAP of our common stock for the seven trading days prior to December 11, 2023, upon conversion of the Note (exclusive of interest), Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note.

We had acquired Elusys Therapeutics in April 2022 (the “Merger Closing Date”), when we consummated the transaction contemplated by the Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with our wholly owned subsidiary (“Merger Sub”), Elusys Therapeutics and Fortis Advisors LLC with Elusys Therapeutics continuing as the surviving entity as our wholly owned subsidiary. Pursuant to the Merger Agreement, as merger consideration  we paid at the closing a cash upfront payment of $3,000,000 to certain of the equity holders of Elusys Therapeutics (the “Sellers”) and assumed and contributed $867,646 to the payment of 50% of certain Elusys lease termination and employee severance payments. We also paid to the Sellers (i) $2,000,000 and (ii) agreed to pay earn out payments for a period of 12 years from the Closing Date equal to 10% of the gross dollar amount of payments received during each one year period during such

7

twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the Merger Closing Date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded or entered into during the first nine years after the Closing Date. We will remain liable for the royalty payments if Elusys Holdings fails to satisfy the obligations it assumed in the Divestiture Transaction. In addition, Elusys Therapeutics shareholders’ received an additional payment of approximately $6.6 million, net from the fulfillment of an existing U.S. Government contract which we agreed to fulfill the future obligations of Elusys under such contract and pass through and distribute to the Sellers the revenue that is received under such contract minus the costs associated with such fulfillment obligations, subject to certain adjustments to the Merger Consideration specified in the Merger Agreement, including income taxes payable with respect to such payments. We also paid an additional $4.2 million to the Sellers pursuant to the terms of the Merger Agreement which further provided that eighty percent of any amounts paid to and received by Elusys Therapeutics after the Merger Closing Date and prior to June 30, 2023 with respect to the sale of 1,500 pre-filled vials of ANTHIM® shall be paid to the Sellers, subject to certain adjustments specified in the Merger Agreement. We also agreed to use commercially reasonable efforts to maintain, finance, operate and promote ANTHIM® and maintain the existing government contract and to continue to operate the Elusys business so as to allow the Sellers to receive the Merger Consideration.

Shared Services Agreement

In connection with the Divestiture Transaction, we entered into a shared services agreement (the “Shared Services Agreement”) with the Buyer setting forth the terms on which we will provide to Buyer, on a transitional basis, certain services or functions that it has historically provided to Elusys. Shared services will include various administrative, accounting, billing, cash management and banking and budgeting services and other support services. In consideration for such services, the Buyer will pay fees to us for the services provided, and those fees will generally be in amounts intended to allow us to recover all of its direct and indirect costs incurred in providing those services. We will charge the Buyer a fee for services performed by (i) our employees which shall be a percentage of each employee’s base salary based upon an allocation of their business time spent providing such services and (ii) third parties, the fees charged by such third parties. Buyer will also pay us for general and administrative expenses incurred by us attributable to both the operation of the Buyer and us (other than the provision of the services performed by us employees) and the provision of the shared services.

License Agreement with Shattuck Labs

In June 2016, we entered into an exclusive license agreement with Shattuck Labs, Inc. (“Shattuck”) pursuant to which we licensed to Shattuck certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us. Shattuck paid us an initial license fee of $50,000 and was obligated to pay us fees upon its receipt of sublicensing income, achievement of certain milestones and royalties upon sales of commercial products. The technology that was out-licensed to Shattuck is in the early stages of development and there is a low likelihood of success for any technology at such stage, and there can be no assurance that any products will be developed by Shattuck or that we will derive any revenue from Shattuck. In February 2023, we were notified by Shattuck that a milestone was met and we received an additional $100,000 in milestone payments. In January, 2024, we entered into a Patent Rights Sale and Assignment Agreement with Kopfkino IP, LLC (“Patent Agreement”) pursuant to which we assigned all of our rights, title, and interest pursuant to the license for consideration of $1,000,000, which was received in January 2024.

Contract Development Biomanufacturing Organization (CDMO) Competition

We formed Scorpius Biomanufacturing to develop bioanalytic, process development, and biomanufacturing capabilities to third parties as a fee-for-service CDMO model. Scorpius is focused on cell- and gene-based therapies as well as large molecule biologics and provides a broad array of services prioritizing American-made equipment, reagents, and materials when possible. Scorpius Biomanufacturing pairs CGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support the advancement of clinical and commercial programs.

We anticipate competing with established biomanufacturers including Lonza Group, WuXi AppTec, Avid Bioservices, and Catalent. The COVID-19 pandemic revealed a critical shortage in U.S. biomanufacturing capacity. Historically, therapies could often take ~10 years to commercialize. However, with the implementation of Emergency Use Authorization, complex, effective vaccines can now advance through pipelines at record speed, contributing to new expectations for time to market, cost reduction, regulatory compliance, and good manufacturing performance. Considering the global cell and gene therapy clinical trials market size was valued at $9.2 billion in 2020 and is expected to expand at a compound annual growth rate (CAGR) of 22.3% from 2021 to 2028 per Grand View Research, we anticipate that a shortage of industry capacity may minimize the risk of direct competition. Additionally, we anticipate Scorpius Biomanufacturing’s prioritization of American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make the organization competitive for U.S. government contracts and biodefense assets. Scorpius Biomanufacturing is focused on manufacturing cell- and gene-based therapies and large molecule biologics.

Intellectual Property

We do not currently own any patents and do not have any patent applications pending in the United States or any foreign countries. However, we have acquired and developed and continue to acquire and develop knowledge and expertise (“know-how”) and trade secrets in the provision of process development and manufacturing services. Our know-how and trade secrets may not be patentable, but they are valuable in that they enhance our ability to provide high-quality services to our customers. We typically place restrictions in our agreements with third-parties, which contractually restrict their right to use and disclose any of our proprietary technology with which they may be involved. In addition, we have internal non-disclosure safeguards, including confidentiality agreements, with our employees.

We also own trademarks to protect the names of our services. Trademark protection continues in some countries as long as the trademark is used, and in other countries, as long as the trademark is registered. Trademark registration is for fixed terms and can be renewed indefinitely.

Government Regulation

CDMO Regulatory Approval

We are required to comply with the regulatory requirements of various local, state, national and international regulatory bodies having jurisdiction in the countries or localities where we manufacture products or where our customers’ products are distributed. In particular, we are subject to laws and regulations concerning research and development, testing, manufacturing processes, equipment and facilities, including compliance with CGMPs, labeling and distribution, import and export, and product registration and listing. As a result, our facilities are subject to regulation by the Food and Drug Administration (“FDA”), as well as regulatory bodies of other jurisdictions where our customers have marketing approval for their products. Scorpius is subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with CGMP and other laws. Accordingly, Scorpius must continue to expend time, money, and effort in the area of production and quality control to maintain CGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved Biologics License Application (“BLA”), including, among other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and claims, are also subject to further FDA review and approval.

We are also required to comply with environmental, health and safety laws and regulations, as discussed in “Environmental and Safety Matters” below. These regulatory requirements impact many aspects of our operations, including manufacturing, developing, labeling, packaging, storage, distribution, import and export and record keeping related to customers’ products. Noncompliance with any applicable regulatory requirements can result in government refusal to approve facilities for manufacturing products or products for commercialization.

Our customers’ products must undergo pre-clinical and clinical evaluations relating to product safety and efficacy before they are approved as commercial therapeutic products. The regulatory authorities having jurisdiction in the countries in which our customers intend to market their products may delay or put on hold clinical trials, delay approval of a product or determine that the product is not approvable. The FDA or other regulatory agencies can delay approval of a drug if our

9

manufacturing facilities are not able to demonstrate compliance with CGMPs, pass other aspects of pre-approval inspections (i.e., compliance with filed submissions) or properly scale up to produce commercial supplies. The FDA and comparable government authorities having jurisdiction in the countries in which our customers intend to market their products have the authority to withdraw product approval or suspend manufacture if there are significant problems with raw materials or supplies, quality control and assurance or the product is deemed adulterated or misbranded. If new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional approvals or operate according to different manufacturing or operating standards or pay additional fees. This may require a change in our manufacturing techniques or additional capital investments in our facilities.

The costs associated with complying with the current and future various applicable local, state, national and international regulations could be significant and the failure to comply with such legal requirements could have an adverse effect on our financial condition and results of operations. See “Risk Factors—Risks Related to Our Business” for additional discussion of the costs associated with complying with the various regulations.

Environmental and Safety Matters

Certain products manufactured by us involve the use, storage and transportation of toxic and hazardous materials. Our operations are subject to extensive laws and regulations relating to the storage, handling, emission, transportation and discharge of materials into the environment and the maintenance of safe working conditions. We maintain environmental and industrial safety and health compliance programs and training at our facilities.

Prevailing legislation tends to hold companies primarily responsible for the proper disposal of their waste even after transfer to third party waste disposal facilities. Other future developments, such as increasingly strict environmental, health and safety laws and regulations, and enforcement policies, could result in substantial costs and liabilities to us and could subject the handling, manufacture, use, reuse or disposal of substances or pollutants at our facilities to more rigorous scrutiny than at present.

Customers

Revenues have historically been derived from a small customer base. Although we continue to expand our customer base, we remain dependent on a limited number of customers for a substantial majority of our revenues. For the years ended December 31, 2023 and 2022, the Company’s major customers were as follows:

	Year Ended
Major Customers	December 31, 2023
Customer A (1)	49%
Customer B	36%
	Year Ended
Major Customers	December 31, 2022
Customer C (1)	94%

(1) Revenue from Customer A and Customer C for each year is now included in Discontinued Operations. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

The loss of, or significant reduction of business from, any of our primary customers will have a material adverse effect on our business, financial condition and results of operations unless we replace such customers with other primary customers. Refer to Note 3, “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements for additional financial information regarding our customer concentration.

Seasonality

Our business is not subject to seasonality. However, the timing of customer orders, the scale, scope, mix, and the duration of our fulfillment of such customer orders can result in variability in our periodic revenues.

10

Backlog

Our backlog represents, as of a point in time, expected future revenue from work not yet completed under signed contracts. As of December 31, 2023, our backlog was approximately $10.4 million, a 156% increase as compared to approximately $4.0 million as of December 31, 2022. While we anticipate a significant amount of our backlog will be recognized over the next year, our backlog is subject to a number of risks and uncertainties, including but not limited to: the risk that a customer timely cancels its commitments prior to our initiation of services, in which case we may be required to refund some or all of the amounts paid to us in advance under those canceled commitments; the risk that a customer may experience delays in its program(s) or otherwise, which could result in the postponement of anticipated services; the risk that we may not successfully execute on all customer projects; and the risk that commencement of customer projects may be postponed due to supply chain delays, any of which could have a negative impact on our liquidity, reported backlog and future revenues and profitability.

Our Corporate Background and Information

We were incorporated under the laws of the State of Delaware on June 10, 2008.

In January 2023, we terminated all license agreements with UM after deciding to de-prioritize research and development efforts. In December 2023, we sold Elusys Therapeutics, Inc. to Elusys Holdings, Inc., a Delaware corporation controlled by the Company’s Chairman, Chief Executive Officer and President, Jeffrey Wolf.

We are a “smaller reporting company”, as defined in Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will cease to be a smaller reporting company if we have (i) more than $250 million in market value of our shares held by non-affiliates as of the last business day of our most recently completed second fiscal quarter or (ii) more than $100 million of annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter and a market value of our shares held by non-affiliates more than $700 million as of the last business day of our second fiscal quarter.

Human Capital

We believe that our success depends upon our ability to attract, develop, retain and motivate key personnel. Our management and scientific teams possess considerable experience in drug discovery, research and development, manufacturing, clinical and regulatory affairs and believe we directly benefit from this experience and industry knowledge.

As of December 31, 2023, we had a total of eighty-four (84) employees, eighty-two (82) full-time and two (2) part-time. Of the total, fifty-six (56) were in CDMO operations, six (6) were in Sales and Marketing, nineteen (19) were in General and Administrative, and three (3) were in Research and Development. All of our employees are based in the United States, with sixty-five (65) in San Antonio, TX and nineteen (19) in various other states. We consider our relationships with our employees to be good. None of our employees is represented by a labor union. We anticipate that we will need to identify, attract, train and retain other highly skilled personnel to pursue our CDMO strategy. Hiring for such personnel is competitive, and there can be no assurance that we will be able to retain our key employees or attract, assimilate or retain the qualified personnel necessary for the development of our business.

Although, management continually seeks to add additional talent to its work force, management believes that it has sufficient human capital to operate its business successfully.

Our compensation programs are designed to align the compensation of our employees with our performance and to provide the proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances incentive earnings for both short-term and long-term performance. Specifically:

● we provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location;

● we engage nationally recognized outside compensation and benefits consulting firms to independently evaluate the effectiveness of our executive compensation and benefit programs and to provide benchmarking against our peers within the industry;

● we attempt to align our executives’ long-term equity compensation with our shareholders’ interests by linking realizable pay with stock performance;

● annual increases and incentive compensation are based on merit,  subject to our financial position, which is communicated to employees at the time of hiring and documented through our talent management process as part of our annual review procedures and upon internal transfer and/or promotion; and

12

● all employees are eligible for health insurance, paid and unpaid leaves, a 401K retirement plan with employer matching contributions (maximum of 4% match) and life and disability/accident coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs.

Item 1A.       Risk Factors

Investors should carefully consider the risks described below before deciding whether to invest in our securities. If any of the following risks actually occur, our business, financial condition or results of operations could be adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Our actual results could differ materially from those anticipated in the forward-looking statements made throughout this Annual Report a result of different factors, including the risks we face described below.

Risks Relating to our Financial Position and Capital Requirements

To date, we have not generated significant revenue and we do not anticipate generating significant revenue in the near future.

To date, we have not generated significant revenue from our business and substantially all of our revenue has been revenue from lines of business in which we are no longer engaged. For the year ended December 31, 2023, we had a net loss of approximately $46.8 million and our revenue was primarily derived from one order of ANTHIM®, and prior to that our revenue was primarily derived from grant revenue that Pelican has received from CPRIT and a small amount of revenue from a research funding agreement. We do not anticipate generating any significant revenue from the provision of CDMO services for several years as we are a new entrant into that line of business. Even if we generate revenue from the provision of services, which is not anticipated for several years, if at all, there can be no assurance that we will be profitable. In addition, we have entered into a new line of business, the provision of contract development and manufacturing services and no assurance can be given that we will be able to generate significant revenue as a contract development and manufacturing organization (“CDMO”) or that we will be able to consummate our business strategy and plans. Financial, technological, market, or other limitations may force us to modify, alter, significantly delay, or significantly impede the implementation of such plans. The operation of the manufacturing facility required us to incur significant expenses before we realize any revenue from such facility. We have insufficient results for investors to use to identify historical trends. Investors should consider our prospects in light of the risk, expenses and difficulties we will encounter as an early-stage company. Our revenue and income potential is unproven and our business model is continually evolving. We are subject to the risks inherent to the operation of a new business enterprise and cannot assure you that we will be able to successfully address these risks.

We need to raise additional capital to support our long-term business plans and our failure to obtain funding when needed may force us to delay, reduce or eliminate our development programs or commercialization efforts.

During the year ended December 31, 2023, our operating activities used net cash of approximately $31.5 million and as of December 31, 2023, our cash and cash equivalents and short-term investments were approximately $2.4 million. During the year ended December 31, 2022, our operating activities used net cash of approximately $5.7 million and as of December 31, 2022 our cash and cash equivalents and short-term investments were approximately $44.3 million. We have experienced significant losses since inception and have a significant accumulated deficit. As of December 31, 2023, our accumulated deficit totaled $254.4 million and as of December 31, 2022, our accumulated deficit totaled $209.2 million on a consolidated basis. We expect to incur additional operating losses in the future and therefore expect our cumulative

13

losses to increase. We do not expect to derive significant revenue from our CDMO services until we expand our customer base. In addition, we expect our expenses to increase due to the operation of the manufacturing facility in San Antonio.

Our current cash is anticipated to be sufficient to fund operations only through late May, 2024. We need to raise additional capital to fund our operations and we cannot be certain that funding will be available to us on acceptable terms on a timely basis, or at all. To meet our financing needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which we expect will include sales of common stock, debt financings, equipment sale leasebacks, and/or funding from partnerships or collaborations. Our ability to raise capital through the sale of securities may be limited by our inability to utilize a registration statement on Form S-3 to raise capital due to the late filing of this Annual Report and various rules of the NYSE American that place limits on the number and dollar amount of securities that we may sell. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. If we fail to raise additional funds on acceptable terms, we may be unable to continue to maintain our listing on the NYSE American. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we have to restructure the company including a work force reduction, or initiate steps to cease operations or liquidate our assets.

We have a limited operating history in our current lines of business.

In 2022, we entered into a new line of business, the provision of contract development and manufacturing services and no assurance can be given that we will be able to generate significant revenue as a CDMO or that we will be able to consummate our business strategy and plans. Financial, technological, market, or other limitations may force us to modify, alter, significantly delay, or significantly impede the implementation of such plans. The operation of the manufacturing facility required us to incur significant expenses before we realize any revenue from such facility. We have insufficient results for investors to use to identify historical trends. Investors should consider our prospects in light of the risk, expenses and difficulties we will encounter as an early-stage company. Our revenue and income potential is unproven and our business model is continually evolving. We are subject to the risks inherent to the operation of a new business enterprise and cannot assure you that we will be able to successfully address these risks.

Our consolidated financial statements have been prepared assuming that we will continue as a going concern.

We have an accumulated deficit of $254.4 million as of December 31, 2023 and a net loss of approximately $46.8 million for the year ended December 31, 2023 and have not generated significant revenue or positive cash flows from operations. We expect to incur significant expenses and continued losses from operations for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we ramp up operations in our in-house bioanalytic, process development and manufacturing facility in San Antonio, TX. Our audited financial statements for the fiscal year ended December 31, 2023 were prepared under the assumption that we will continue as a going concern; however, we have incurred significant losses from operations to date and we expect our expenses to increase in connection with our ongoing activities. These factors raise substantial doubt about our ability to continue as a going concern for one year after the financial statements are issued. Our auditors also included an explanatory paragraph in its report on our financial statements as of and for the year ended December 31, 2023 with respect to this uncertainty.  There can be no assurance that funding will be available on acceptable terms on a timely basis, or at all. The various ways that we could raise capital carry potential risks. Any additional sources of financing will likely involve the issuance of our equity securities, which will have a dilutive effect on our stockholders. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. If we raise funds through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or tests or grant licenses on terms that are not favorable to us. If we do not succeed in raising additional funds on acceptable terms or at all, we may be unable to develop any new product candidates that we acquire. As such, we cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements included in this Annual Report are filed with the SEC and there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

14

We have incurred net losses every year since our inception and expect to continue to incur increased expenses and generate operating losses and experience negative cash flows and it is uncertain whether we will achieve profitability.

For the years ended December 31, 2023 and 2022, we incurred a net loss of $46.8 million and $43.9 million, respectively. We have an accumulated deficit of $254.4 million through December 31, 2023. We expect to continue to incur operating losses until such time, if ever, as we are able to achieve sufficient levels of revenue from operations. As stated above, we do not anticipate generating significant revenue from sales of our products for several years or from our manufacturing facility until such time as it is fully operational and operating at full capacity. Our ability to achieve profitability will depend on us successfully as a CDMO and market acceptance of our services and our capacity to develop, introduce and sell our services to our targeted markets. Furthermore, there can be no assurance that we generate sufficient revenue from manufacturing services to support the expenses anticipated to be incurred by the manufacturing facility. Accordingly, the extent of future losses and the time required to achieve profitability, if ever, cannot be predicted at this point.

Even if we succeed in generating revenue as a CDMO, we expect to incur substantial losses for the foreseeable future and may never become profitable. We also expect to continue to incur significant operating expenses and anticipate that our expenses will increase substantially in the foreseeable future as we:

● implement additional internal systems and infrastructure;

● devote resources to constructing a facility for the further development of bioanalytics, process development and biomanufacturing activities; and

● hire additional personnel.

We also expect to experience negative cash flows for the foreseeable future as we fund our operating losses. As a result, we will need to generate significant revenues or raise additional financing in order to achieve and maintain profitability. We may not be able to generate these revenues or achieve profitability in the future. Our failure to achieve or maintain profitability would likely negatively impact the value of our securities and financing activities. If we do not raise capital or successfully engage a stragtegic partner in the near term, we may be required to delay, reduce, or terminate some or all of our operations, sell some of our assets, cease operations, liquidate our assets or reorganize the Company, or a combination of the foregoing.

We face risks related to the restatement of our previously issued financial statements for the quarters ended June 30, 2022 and September 30, 2022.

As previously disclosed, we reached a determination to restate our unaudited consolidated financial statements included in  the quarterly reporting periods during fiscal year 2022, consisting of June 30, 2022 and September 30, 2022 and that such interim financial statements should no longer be relied upon. As a result, we have incurred unanticipated costs for accounting and legal fees in connection with or related to the restatement, and have become subject to a number of additional risks and uncertainties, which may affect investor confidence in the accuracy of our financial disclosures and may raise reputational issues for our business. we expect to continue to face many of the risks and challenges related to the restatement, including the following:

● we may fail to remediate material weaknesses in our internal control over financial reporting and other material weaknesses may be identified in the future, which would adversely affect the accuracy and timing of our financial reporting; 

● the processes undertaken to effect the restatement may not have been adequate to identify and correct all errors in our historical financial statements and, as a result, we may discover additional errors and our financial statements remain subject to the risk of future restatement; 

● the incurrence of restatement-related expenses; and

● diversion of management and other human resources attention from the operation of our business.

We cannot assure that all of the risks and challenges described above will be eliminated and that lost business opportunities can be recaptured or that general reputational harm will not persist. If one or more of the foregoing risks or challenges persist, our business, operations and financial condition are likely to be materially and adversely affected

15

We identified a material weakness in our internal control over financial reporting and determined that our disclosure controls and procedures were ineffective as of June 30, 2022 and September 30, 2022 as well as of December 31, 2022. As a result, we restated our quarterly financial results for the periods ending June 30, 2022 and September 30, 2022. This material weakness continues to exist as of December 31, 2023. In the future, we may identify additional material weaknesses or otherwise fail to maintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material errors in our financial statements or cause us to fail to meet our period reporting obligations.

Management and our Audit Committee, in consultation with BDO USA P.C. (“BDO”), our independent registered public accounting firm, determined that our previously issued interim financial statements filed on the Form 10-Q, as of June 30, 2022, and for the three and six months ended June 30, 2022 and three and nine months ended September 30, 2022 should no longer be relied upon. Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for evaluating and reporting on the effectiveness of our system of internal control. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America. As a public company, we are required to comply with the Sarbanes-Oxley Act and other rules that govern public companies. In particular, we are required to certify our compliance with Section 404 of the Sarbanes-Oxley Act, which requires us to furnish annually a report by management on the effectiveness of our internal control over financial reporting.

Management has concluded that in light of the errors described above, a material weakness in our internal controls over financial reporting existed and management’s assessment of the effectiveness of our disclosure controls and procedures as of June 30, 2022 and September 30, 2022 set forth in its Quarterly Reports on Form 10-Q for the quarters ended June 30, 2022 and September 30, 2022 had to be modified to include a material weakness in its controls over financial reporting.  The material weakness identified relates to the ineffective design of management review controls over the computation and disclosure of income taxes. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. The existence of one or more material weaknesses precludes a conclusion by management that our disclosure controls and procedures and internal control over financial reporting are effective. As a result of the material weakness, we believe that our internal control over financial reporting was not effective and our disclosure controls and procedures were not effective for the Non-Reliance Periods. In preparing our audited financial statements for the fiscal year ended December 31, 2023, we determined that the material weakness still exists in the Company’s internal controls over financial reporting and our disclosure controls were ineffective. Management is committed to the remediation of the material weakness. Management is actively engaged in the implementation of remediation efforts, as described above to address the material weakness.

If we are not able to comply with the requirements of the Sarbanes-Oxley Act or if we are unable to maintain effective internal control over financial reporting, we may not be able to produce timely and accurate financial statements or guarantee that information required to be disclosed by us in the reports that we file with the SEC, is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Any failure of our internal control over financial reporting or disclosure controls and procedures could cause our investors to lose confidence in our publicly reported information, cause the market price of our stock to decline, expose us to sanctions or investigations by the SEC or other regulatory authorities, or impact our results of operations.

We have a limited operating history conducting commercial development of bioanalytics, process development and manufacturing activities, which may limit the ability of investors to make an informed investment decision.

To date, we have limited experience manufacturing products for third parties and ourselves. Because of the numerous risks and uncertainties associated with development and manufacturing, we are unable to predict if we will be successful in providing such services to ourselves or third parties. Our ability to generate this revenue will depend, in part, on our ability to attract and maintain customers for our development, manufacturing and technology transfer services and on the amount spent by the customers on such services. If our facility fails to attract customers and operate at sufficient capacity, our margins will suffer, and we may not be able to fund the costs we incur to operate it. Our bioanalytics, process development

16

and biomanufacturing activities will also depend, in part, on our ability to attract and retain an appropriately skilled and sufficient workforce to operate our development and manufacturing facility and our ability to comply with various quality standards and environmental, health and safety laws and regulations.

We depend on spending and demand from our customers for our contract manufacturing and development services and any reduction in spending or demand could have a material adverse effect on our business.

The amount that our customers spend on the development and manufacturing of their products or product candidates, particularly the amount our customers choose to spend on outsourcing these services to us, substantially impacts our revenue. The outcomes of our customers’ research, development and marketing also significantly influence the amount that our customers choose to spend on our services and offerings. Our customers determine the amounts that they will spend on our services based upon, among other things, the clinical and market success of their products, available resources, access to capital and their need to develop new products which, in turn, depend upon a number of other factors, including their competitors’ research, development and product initiatives and the anticipated market for any new products, as well as clinical and reimbursement scenarios for specific products and therapeutic areas. Further, increasing consolidation in the pharmaceutical industry may impact such spending, particularly in the event that any of our customers choose to develop or acquire integrated manufacturing operations. Any reduction in customer spending on biologics development and related services as a result of these and other factors could have a material adverse effect on our business, financial condition, and results of operations. Available resources, the need to develop new products, and consolidation in the industries in which our customers operate may have an impact on such spending. Our customers finance their research and development spending from private and public sources. A reduction in spending by our customers, which may be influenced by the recent sharp downturn in available private and public funding for small and emerging biotechnology companies, could have a material adverse effect on our business, financial condition, and results of operations. If our customers are not successful in attaining or retaining product sales due to market conditions, reimbursement issues, or other factors, our results of operations may be materially adversely affected.

To date, our revenues have come from a limited number of customers, making us dependent on those few customers.

For the year ended December 31, 2023, substantially all of our revenue was derived from a limited number of customers. Though we continue to expand our customer base, we remain dependent on a limited number of customers for a substantial majority of our revenues. For the year ended December 31, 2023, revenue from two cusotomers accounted for 85% of total revenue . For the year ended December 31, 2022, revenue from one customer accounted for 94% of total revenue. One customer accounted for 36% of our revenue for the fiscal year ended December 31, 2023, and is migrating to a larger CDMO for commercial manufacture of their product. The loss of, or a significant reduction of business from, any of our primary customers will have a material adverse effect on our business, financial condition, and results of operation unless we are able to replace such customers with other primary customers.

We generally do not have long-term CDMO customer contracts and our backlog cannot be relied upon as a future indicator of revenues.

We generally do not have long-term contracts with our CDMO customers, and existing contracts and purchase commitments may be canceled under certain circumstances. As a result, we are exposed to market and competitive price pressures on every order, and our agreements with customers do not provide assurance of future revenues. Our customers are not required to make minimum purchases and, in certain circumstances, may cease using our services at any time without penalty. Our backlog should not be relied on as a measure of anticipated demand or future revenue, because the orders constituting our backlog may be subject to changes in delivery schedules or cancellation without significant penalty to the customer. Any reductions, cancellations or deferrals in customer orders would negatively impact our business.

All of our manufacturing services are conducted at our facility situated in San Antonio, Texas, which increases our exposure to significant disruption to our business as a result of unforeseeable developments in a single geographic area.

We operate one manufacturing facility in one location, San Antonio, Texas. It is possible that we could experience prolonged periods of reduced production due to unforeseen catastrophic events occurring in or around our facilities. It is

17

also possible that operations could be disrupted due to other unforeseen circumstances such as power outages, explosions, fires, floods, earthquakes or accidents. As a result, we may be unable to shift manufacturing capabilities to alternate locations, accept materials from suppliers, meet customer shipment needs or address other severe consequences that may be encountered, and we may suffer damage to our reputation. Our financial condition and results of our operations could be materially adversely affected were such events to occur.

The operations of our business and our suppliers’ business could also be subject to business interruptions.

Our business and the business of the raw material suppliers could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other health crisis, such as the outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect our planned operations. Such events could result in the complete or partial closure of our manufacturing facilities. In addition, it could impact economies and financial markets, resulting in an economic downturn that could impact our ability to raise capital or slow down potential partnering relationships.

We rely on third parties to supply most of the necessary raw materials and supplies for the products we manufacture on behalf of our customers and our inability to obtain such raw materials or supplies may adversely impact our business, financial condition, and results of operations.

Our operations require various raw materials, including proprietary media, resins, buffers, and filters, in addition to numerous additional raw materials supplied primarily by third parties. We or our customers specify the raw materials and other items required to manufacture their product and, in some cases, specify the suppliers from whom we must purchase these raw materials. In certain instances, the raw materials and other items can only be supplied by a limited number of suppliers and, in some cases, a single source, or in limited quantities. If third-party suppliers do not supply raw materials or other items on a timely basis, it may cause a manufacturing run to be delayed or canceled which would adversely impact our financial condition and results of operations. Additionally, we do not have long-term supply contracts with any of our single source suppliers. If we experience difficulties acquiring sufficient quantities of required materials or products from our existing suppliers, or if our suppliers are found to be non-compliant with the FDA’s quality system regulation, CGMPs or other applicable laws or regulations, we would be required to find alternative suppliers. If our primary suppliers become unable or unwilling to perform, any resulting delays or interruptions in the supply of raw materials required to support our manufacturing of CGMP pharmaceutical-grade products would ultimately delay our manufacture of products for our customers, which could materially and adversely affect our financial condition and operating results. Furthermore, third-party suppliers may fail to provide us with raw materials and other items that meet the qualifications and specifications required by us or our customers. If third-party suppliers are not able to provide us with raw materials that meet our or our customers’ specifications on a timely basis, we may be unable to manufacture their product or it could prevent us from delivering products to our customers within required timeframes. Any such delay in delivering our products may create liability for us to our customers for breach of contract or cause us to experience order cancellations and loss of customers. In the event that we manufacture products with inferior quality components and raw materials, we may become subject to product liability claims caused by defective raw materials or components from a third-party supplier or from a customer, or our customer may be required to recall its products from the market.

Our manufacturing services are highly complex, and if we are unable to provide quality and timely services to our customers, our business could suffer.

The manufacturing services we offer are highly complex, due in part to strict regulatory requirements. A failure of our quality control systems in our facility could cause problems to arise in connection with facility operations for a variety of reasons, including equipment malfunction, viral contamination, failure to follow specific manufacturing instructions, protocols and standard operating procedures, problems with raw materials or environmental factors. Such problems could affect production of a single manufacturing run or a series of runs, requiring the destruction of products, or could halt manufacturing operations altogether. In addition, our failure to meet required quality standards may result in our failure to timely deliver products to our customers which, in turn, could damage our reputation for quality and service. Any such incident could, among other things, lead to increased costs, lost revenue, reimbursement to customers for lost drug substance, damage to and possibly termination of existing customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to other manufacturing runs. With respect to our

18

commercial manufacturing, if problems are not discovered before the product is released to the market, we may be subject to regulatory actions, including product recalls, product seizures, injunctions to halt manufacture and distribution, restrictions on our operations, civil sanctions, including monetary sanctions, and criminal actions. In addition, such issues could subject us to litigation, the cost of which could be significant.

We are dependent upon our customers’ ability to receive and maintain regulatory approval for their product candidates which negatively impact our revenues and profitability.

Our success depends upon the regulatory approval of the products we manufacture. As such, if our customers experience a delay in, or failure to receive, approval for any of their product candidates or fail to maintain regulatory approval of their products and we are not able to manufacture these products, our revenue and profitability could be adversely affected. Additionally, if the FDA or a comparable foreign regulatory authority does not approve of our facilities for the manufacture of a customer product or if it withdraws such approval in the future, our customers may choose to identify alternative manufacturing facilities and/or relationships, which could significantly impact our ability to expand our manufacturing capacity and capabilities and achieve profitability.

Our business is dependent upon the demand for our services by our customers.

Our business is dependent upon the amount of money our customers choose to spend on development and manufacturing services. A decrease in the budget of our customers for spending on development and manufacturing services will negatively impact our revenue and profitability. Early stage customers may be forced to delay or cancel our services in an effort to conserve cash which could have a material adverse effect on our revenues and profitability. In addition, the outcomes of our customers’ research, development and marketing also significantly influence the amount that our customers choose to spend on our services and offerings. Further, increasing consolidation in the pharmaceutical industry may impact such spending, particularly in the event that any of our customers choose to develop or acquire integrated manufacturing operations. Any reduction in customer spending on biologics development and related services as a result of these and other factors could have a material adverse effect on our business, financial condition, and results of operations.

If we use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.

Our contract manufacturing operations involve the controlled use of hazardous materials and chemicals. We are subject to federal, state and local laws and regulations in the United States governing the use, manufacture, storage, handling and disposal of hazardous materials and chemicals. Although we believe that our procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we may incur significant additional costs to comply with applicable laws in the future. Also, even if we are in compliance with applicable laws, we cannot completely eliminate the risk of contamination or injury resulting from hazardous materials or chemicals. As a result of any such contamination or injury, we may incur liability or local, city, state or federal authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our contract manufacturing operations, which could materially harm our business, financial condition and results of operations.

If our acquired intangible assets become impaired, we may be required to record a significant charge to earnings.

We regularly review acquired intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. We test goodwill and indefinite-lived intangible assets for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of the intangible assets may not be recoverable, include: macroeconomic conditions, such as deterioration in general economic conditions; industry and market considerations, such as deterioration in the environment in which we operate; cost factors, such as increases in labor or other costs that have a negative effect on earnings and cash flows; our financial performance, such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; other relevant entity-specific events, such as changes in management, key personnel,

19

strategy, or customers; and sustained decreases in share price. In 2023, goodwill impairment of $3.9 million and intangible asset impairment of $2.3 million was recorded but is now reported with discontinued operations. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information. During the year ended December 31, 2022 we recorded an indefinite-lived intangible assets impairment charge of $3.5 million.

If Elusys Holdings should fail to fulfill the royalty payment obligations under the Merger Agreement, we will be liable for such payments.

The Merger Agreement provides that Elusys Therapeutics will pay earn out payments for a period of 12 years from the Closing Date equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the Closing Date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded or entered into during the first nine years after the Closing Date. The Merger Agreement also provides that we will remain liable for royalty payment obligations if any buyer of Elusys Therapeutics fails to satisfy this obligation.

We rely on key executive officers and scientific and medical advisors, and their knowledge of our business and technical expertise would be difficult to replace.

We are highly dependent on our principal scientific, regulatory and medical advisors and our chief executive officer. Other than a $2.0 million insurance policy we hold on the life of Jeffrey Wolf, we do not have “key person” life insurance policies for any of our officers or advisors. The loss of the technical knowledge, management and industry expertise of any of our key personnel could result in delays in product development, loss of customers and sales and diversion of management resources, which could adversely affect our operating results.

Certain members of our management team serve as executive officers of the entity that owns Elusys Therapeutics, which may give rise to potential conflicts of interest.

Our Chief Executive Officer and Chief Financial Officer are also officers and/or directors of the entity that owns Elusys Therapeutics. Accordingly, there may be possible conflicts of interest if we should perform manufacturing services for such entity as well as with respect to allocation of time.

Risks Related to Regulatory Approval and Commercialization

Failure to comply with existing and future regulatory requirements for our CDMO could adversely affect our business, financial condition, and results of operations.

Our industry is highly regulated. We are required to comply with the regulatory requirements of various local, state, provincial, national and international regulatory bodies having jurisdiction in the countries or localities in which we manufacture products or in which our customers’ products are distributed. In particular, our CDMO is subject to laws and regulations concerning development, testing, manufacturing processes, equipment and facilities, including compliance with CGMPs, import and export, and product registration and listing, among other things. As a result, our facility is subject to regulation by the FDA, as well as regulatory bodies of other jurisdictions where our customers have marketing approval for their products including, but not limited to, the EMA, ANVISA and/or Health Canada, depending on the countries in which our customers market and sell the products we manufacture on their behalf. It is possible that compliance with new regulatory requirements could impose significant compliance costs on us. Such costs could have a material adverse effect on our business, financial condition and results of operations.

These regulatory requirements impact many aspects of our operations, including manufacturing, developing, storage, distribution, import and export and record keeping related to customers’ products. Noncompliance with any applicable regulatory requirements can result in government refusal to approve: (i) facilities for testing or manufacturing products or (ii) products for commercialization. The FDA and other regulatory agencies can delay, limit or deny approval for many reasons, including:

20

● changes to the regulatory approval process, including new data requirements for product candidates in those jurisdictions, including the United States, in which our customers may be seeking approval;

● that a customer’s product candidate may not be deemed to be safe or effective;

● the inability of the regulatory agency to provide timely responses as a result of its resource constraints; and

● that the manufacturing processes or facilities may not meet the applicable requirements.

In addition, if new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional approvals or operate according to different manufacturing or operating standards. This may require a change in our development and manufacturing techniques or additional capital investments in our facilities. Any related costs may be significant. If we fail to comply with applicable regulatory requirements in the future, then we may be subject to warning letters and/or civil or criminal penalties and fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, restrictions on the import and export of the products we manufacture, debarment, exclusion, disgorgement of profits, operating restrictions and criminal prosecution and the loss of contracts and resulting revenue losses. Inspections by regulatory authorities that identify any deficiencies could result in remedial actions, production stoppages or facility closure, which would disrupt the manufacturing process and supply of product to our customers. In addition, such failure to comply could expose us to contractual and product liability claims, including claims by customers for reimbursement for lost or damaged active pharmaceutical ingredients or recall or other corrective actions, the cost of which could be significant.

In addition, certain products we manufacture must undergo pre-clinical and clinical evaluations relating to product safety and efficacy before they are approved as commercial therapeutic products. The regulatory authorities having jurisdiction in the countries in which our customers intend to market their products may delay or put on hold clinical trials or delay approval of a product or determine that the product is not approvable. The FDA or other regulatory agencies can delay approval of a drug if our manufacturing facility, including any newly commissioned facility, is not able to demonstrate compliance with CGMPs, pass other aspects of pre-approval inspections or properly scale up to produce commercial supplies. The FDA and comparable government authorities having jurisdiction in the countries in which we or our customers intend to market their products have the authority to withdraw product approval or suspend manufacture if there are significant problems with raw materials or supplies, quality control and assurance or the product we manufacture is adulterated or misbranded. If our manufacturing facilities and services are not in compliance with FDA and comparable government authorities, we may be unable to obtain or maintain the necessary approvals to continue manufacturing products for our customers, which would materially adversely affect our financial condition and results of operations.

We may be exposed to liability claims associated with the use of biological and hazardous materials and chemicals.

Our research and development activities and CDMO services we provide may involve the controlled use of biological and hazardous materials and chemicals. Although we believe that our safety procedures for using, storing, handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot completely eliminate the risk of accidental injury or contamination from these materials. We currently operate a facility in Texas where we perform contract services for third parties that could involve the use of biological and hazardous materials and chemicals. In the event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products may require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and results of operations.

21

We may incur substantial liabilities and may be required to limit commercialization of our products in response to product liability lawsuits.

The testing and marketing of drug and biological product candidates entail an inherent risk of product liability. Product liability claims might be brought against us by consumers, health care providers or others selling or otherwise coming into contact with our products. In our facility in San Antonio we perform CDMO services for third parties.  We could incur liability in the performance of these services, including liability for damage to materials supplied to us. If any of the products or services we develop are used in clinical trials, clinical trial liability claims may be filed against us for damages suffered by clinical trial subjects or their families. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products which could impact our ability to continue as a going concern. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with collaborators. In addition, regardless of merit or eventual outcome, product liability claims may result in:

● decreased demand for any approved product candidates;

● impairment of our business reputation;

● withdrawal of clinical trial participants;

● costs of related litigation;

● distraction of management’s attention;

● substantial monetary awards to patients or other claimants;

● loss of revenues; and

● the inability to successfully commercialize any approved drug candidates.

Uncertainty regarding health care reform and declining general economic or business conditions may have a negative impact on our business.

Continuing concerns over U.S. health care reform legislation and energy costs, geopolitical issues, the availability and cost of credit and government stimulus programs in the United States and other countries have contributed to increased volatility and diminished expectations for the global economy. If the economic climate does not improve or continues to be uncertain, our business, as well as the financial condition of our customers and suppliers, could be adversely affected, resulting in a negative impact on our business, financial condition and results of operations.

We rely extensively on our information technology systems and are vulnerable to damage and interruption.

We rely on our information technology systems and infrastructure to process transactions, summarize results and manage our business, including maintaining client and supplier information. Additionally, we utilize third parties, including cloud providers, to store, transfer and process data. Our information technology systems, as well as the systems of our suppliers and other partners, whose systems we do not control, are vulnerable to outages and an increasing risk of continually evolving deliberate intrusions to gain access to company sensitive information. Likewise, data security incidents and breaches by employees and others with or without permitted access to our systems pose a risk that sensitive data may be exposed to unauthorized persons or to the public. A cyber-attack or other significant disruption involving our information technology systems, or those of our vendors, suppliers and other partners, could also result in disruptions in critical systems, corruption or loss of data and theft of data, funds or intellectual property. We may be unable to prevent outages or security breaches in our systems. We remain potentially vulnerable to additional known or yet unknown threats as, in some instances, we, our suppliers and our other partners may be unaware of an incident or its magnitude and effects. We also face the risk that we expose our vendors or partners to cybersecurity attacks. Any or all of the foregoing could adversely affect our results of operations and our business reputation.

22

Any failure to maintain the security of information relating to our customers, employees and suppliers, whether as a result of cybersecurity attacks or otherwise, could expose us to litigation, government enforcement actions and costly response measures, and could disrupt our operations and harm our reputation.

In connection with the sales and marketing of our products and services, we may from time to time transmit confidential information. We also have access to, collect or maintain private or confidential information regarding our clinical trials and the patients enrolled therein, employees, and suppliers, as well as our business. Cyberattacks are rapidly evolving and becoming increasingly sophisticated. In addition, if we manufacturer biodefense products sold to the U.S. government, such as ANTHIM, we will have access to highly confidential government information. It is possible that computer hackers and others might compromise our security measures, or security measures of those parties that we do business with now or in the future and obtain the personal information of patients in our clinical trials, vendors, employees and suppliers or our business information. A security breach of any kind, including physical or electronic break-ins, computer viruses and attacks by hackers, employees or others, could expose us to risks of data loss, litigation, government enforcement actions, regulatory penalties and costly response measures, and could seriously disrupt our operations. Any resulting negative publicity could significantly harm our reputation, which could cause us to lose market share and have an adverse effect on our results of operations.

Our operating results may be adversely affected by fluctuations in foreign currency exchange rates and restrictions on the deployment of cash across global operations.

Although we report operating results in U.S. dollars, if we engage in sales of products internationally, our revenues and expenses are or will be denominated in currencies other than the U.S. dollar, particularly in Europe. Fluctuations in foreign currency exchange rates can have a number of adverse effects on us. Because our consolidated financial statements are presented in U.S. dollars, we will be required to translate revenues, expenses and income, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, changes in the value of the U.S. dollar against other currencies will affect revenues, income from operations, other income (expense), net and the value of balance sheet items originally denominated in other currencies. There is no guarantee that our financial results will not be adversely affected by currency exchange rate fluctuations. In addition, in some countries we could be subject to strict restrictions on the movement of cash and the exchange of foreign currencies, which could limit our ability to use these funds across our global operations.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act (“FCPA”) and other worldwide anti-bribery laws.

The FCPA and anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or other commercial advantage. Our policies mandate compliance with these anti-bribery laws, which often carry substantial penalties, including criminal and civil fines, potential loss of export licenses, possible suspension of the ability to do business with the federal government, denial of government reimbursement for products and exclusion from participation in government health care programs. We may operate in jurisdictions that have experienced governmental and private sector corruption to some degree, and, in certain circumstances, strict compliance with anti-bribery laws may conflict with certain local customs and practices. We cannot assure you that the internal control policies and procedures always will protect us from reckless or other inappropriate acts committed by affiliates, employees or agents. Violations of these laws, or allegations of such violations, could have a material adverse effect on our business, financial position and results of operations.

Risks Related to Intellectual Property

We have limited protection for our intellectual property, which could impact our competitive position.

We intend to rely on a combination of common law copyright, patent, trademark, and trade secret laws and measures to protect our proprietary information and technology. We may be unable to prevent unauthorized use of such information and technology. Patent, trademark and copyright protections may be limited, and enforcement could be too costly to be effective. It may also be possible for unauthorized third parties to copy aspects of, or otherwise obtain and use, our proprietary information without authorization, including, but not limited to, product design, software, customer and

23

prospective customer lists, trade secrets, copyrights, patents and other proprietary rights and materials. Other parties can use and register confusingly similar business, product and service names, as well as domain names, which could divert customers, resulting in a material adverse effect on our business, operating results and financial condition.

Intellectual property rights may also be unavailable or limited in some foreign countries, which could make it easier for competitors to capture market share. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our proprietary rights generally. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties.

If we fail to successfully enforce our intellectual property rights, our competitive position could suffer, which could harm our operating results. Competitors may challenge the validity or scope of our intellectual property rights we may obtain. We may be required to spend significant resources to monitor and police our intellectual property rights. We may not be able to detect infringement and our competitive position may be harmed. Proceedings to enforce our rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. In addition, competitors may design around our technology or develop competing technologies.

Our technology, our products or our development efforts may be found to infringe upon third-party intellectual property rights.

Third parties may in the future assert claims or initiate litigation related to their patent, copyright, trademark and other intellectual property rights in technology that is important to us. The asserted claims and/or litigation could include claims against us, our suppliers alleging infringement of intellectual property rights with respect to our proprietary rights. Regardless of the merit of the claims, they could be time consuming, result in costly litigation and diversion of technical and management personnel, or require us to develop a non-infringing technology or enter into license agreements. We have not undertaken an exhaustive search to discover any third party intellectual patent rights, which might be infringed by commercialization of the product candidates described herein. Although we are not currently aware of any such third-party intellectual patent rights, it is possible that such rights currently exist or might be obtained in the future. In the event that a third party controls such rights and we are unable to obtain a license to such rights on commercially reasonable terms, we may not be able to sell or continue to develop our products, and may be liable for damages for such infringement. We cannot assure you that licenses will be available on acceptable terms, if at all. Furthermore, because of the potential for significant damage awards, which are not necessarily predictable, it is not unusual to find even arguably unmeritorious claims resulting in large settlements. If any infringement or other intellectual property claim made against us by any third party is successful, or if we fail to develop non-infringing technology or license the proprietary rights on commercially reasonable terms and conditions, our business, operating results and financial condition could be materially adversely affected.

If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we could incur substantial costs and we may have to:

● obtain licenses, which may not be available on commercially reasonable terms, if at all;

● abandon an infringing drug or therapy candidate;

● redesign our products or processes to avoid infringement;

● stop using the subject matter claimed in the patents held by others;

● pay damages; or

● defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources.

24

General Risk Factors

Changes in general economic conditions, geopolitical conditions, domestic and foreign trade policies, monetary policies and other factors beyond our control may adversely impact our business and operating results.

Our operations and performance depend on global, regional and U.S. economic and geopolitical conditions. General worldwide economic conditions have experienced significant instability in recent years including the recent global economic uncertainty and financial market conditions. Russia’s invasion and military attacks on Ukraine have triggered significant sanctions from U.S. and European leaders and financial markets around the world experienced volatility following the invasion of Ukraine by Russia in February 2022. Resulting changes in U.S. trade policy could trigger retaliatory actions by Russia, its allies and other affected countries, including China, resulting in a “trade war.” Furthermore, if other countries, including the U.S., become further involved in the conflict, we could face significant adverse effects to our business and financial condition. In addition, the global macroeconomic environment could be negatively affected by, among other things, instability in global economic markets, increased U.S. trade tariffs and trade disputes with other countries, instability in the global credit markets, supply chain weaknesses, instability in the geopolitical environment as a result of the withdrawal of the United Kingdom from the European Union, the war in the Middle East and other political tensions, and foreign governmental debt concerns. Such challenges have caused, and may continue to cause, uncertainty and instability in local economies and in global financial markets.

The uncertain financial markets, disruptions in supply chains, mobility restraints, and changing priorities as well as volatile asset values could impact our business in the future. The COVID-19 outbreak and government measures taken in response to the pandemic have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, have spiked, while demand for other goods and services, such as travel, have fallen. A resurgence of COVID 19, or other pandemics or epidemics could have an adverse effect on our business and operations are uncertain.

Further, although we have not experienced any material adverse effects on our business due to increasing inflation, it has raised operating costs for many businesses and, in the future, could impact demand or pricing manufacturing of our drug candidates or services providers, foreign exchange rates or employee wages. Inflation rates, particularly in the United States and United Kingdom, have increased recently to levels not seen in years, and increased inflation may result in increases in our operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or otherwise raise capital. In addition, the Federal Reserve has raised, and may again raise, interest rates in response to concerns about inflation, which coupled with reduced government spending and volatility in financial markets may have the effect of further increasing economic uncertainty and heightening these risks.

Actual events involving reduced or limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation as receiver.  Although we did not have any cash or cash equivalent balances on deposit with Silicon Valley Bank, uncertainty and liquidity concerns in the broader financial services industry remain and the failure of Silicon Valley Bank and its potential near- and long-term effects on the biotechnology industry and its participants such as our vendors, suppliers, and investors, may also adversely affect our operations and stock price.

We are actively monitoring the effects these disruptions and increasing inflation could have on our operations. These conditions make it extremely difficult for us to accurately forecast and plan future business activities.

These conditions make it extremely difficult for us to accurately forecast and plan future business activities.

In addition, the outbreak of a pandemic could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory facilities, or due to quarantines. Pandemics could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

25

We may not successfully effect our intended expansion, which would harm our business prospects.

Our success will depend upon the expansion of our operations and the effective management of our growth, which will place a significant strain on our management, and on our administrative, operational and financial resources. To manage this growth, we must expand our facilities; augment our operational, financial and management systems; and hire and train additional qualified personnel. If we are unable to manage our growth effectively, our business would be harmed.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future, and as a result, investors in our common stock could incur substantial losses and our ability to raise funds may be impacted.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future. On December 19, 2023, the reported low sale price of our common stock was $0.258 per share and the reported high sales price was $1.29 per share on January 24, 2023. For comparison purposes, on December 29, 2023, the price of our common stock closed at $0.44 per share. We may incur rapid and substantial decreases in our stock price in the foreseeable future that are unrelated to our operating performance or prospects. The stock market generally and the market for biotechnology and pharmaceutical companies in particular has experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may experience losses on their investment in our common stock. The market price for our common stock may be influenced by many factors, including the following:

● investor reaction to our business strategy;

● the success of competitive products or technologies;

● our continued compliance with the listing standards of the NYSE American;

● regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our products;

● actions taken by regulatory agencies with respect to the products we manufacture, manufacturing process

● variations in our financial results or those of companies that are perceived to be similar to us;

● the success of our efforts to acquire or in-license additional products or product candidates;

● developments concerning our collaborations or partners;

● developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our products;

● our ability to generate revenue from our CDMO facility;

● our ability or inability to raise additional capital and the terms on which we raise it;

● declines in the market prices of stocks generally;

● trading volume of our common stock;

● sales of our common stock by us or our stockholders;

● general economic, industry and market conditions; and

● other events or factors, including those resulting from such events, or the prospect of such events, including war, terrorism and other international conflicts, such as the Russian invasion of Ukraine, and the Israeli conflict, public health issues including health epidemics or pandemics, and natural disasters such as fire, hurricanes, earthquakes, tornados or other adverse weather and climate conditions, whether occurring in the United States or elsewhere, could disrupt our operations, disrupt the operations of our suppliers or result in political or economic instability.

These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Since the stock price of our common stock has fluctuated in the past, has been recently volatile and may be volatile in the future, investors in our common stock could incur substantial losses. In the past, following periods of volatility in the market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.

26

There can be no guarantee that our stock price will remain at current prices or that future sales of our common stock will not be at prices lower than those sold to investors.

If we are unable to hire additional qualified personnel, our ability to grow our business may be harmed.

We will need to hire additional qualified personnel with expertise in preclinical and clinical research, government regulation, formulation and manufacturing, sales and marketing and accounting and financing. Over the next 12 months, we expect to hire additional new employees in Texas. We compete for qualified individuals with numerous biopharmaceutical companies, universities, and other research institutions. Competition for such individuals is intense, and we cannot be certain that our search for such personnel will be successful. Attracting and retaining qualified personnel will be critical to our success.

We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

We are a smaller reporting company under Rule 12b-2 of the Exchange Act. For as long as we continue to be a smaller reporting company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on smaller reporting company exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile.

There can be no assurance that we will be able to comply with the applicable regulations in a timely manner, if at all.

Our failure to meet the continued listing requirements of the NYSE American LLC (the “NYSE American”) could result in a de-listing of our common stock.

Our shares of common stock are currently listed on the NYSE American. On April 17, 2024, we received an official notice of noncompliance (the “NYSE American Notice”) from NYSE Regulation stating that we are not in compliance with NYSE American continued listing standards (the “Filing Delinquency Notification”) under the timely filing criteria included in Section 1007 of the NYSE American Company Guide (the "Company Guide") due to the failure to timely file this Annual Report on Form 10-K (the “Delinquent Report”) by the filing due date of April 16, 2024 (the “Filing Delinquency”.)

We believe that upon the filing of this Annual Report on Form 10-K we will have cured the Filing Delinquency, however there can be no assurance that we will continue to comply with the NYSE American continued listing requirements. If we fail to satisfy the continued listing requirements of the NYSE American, such as the corporate governance requirements, minimum bid price requirement or the minimum stockholder’s equity requirement, NYSE American may take steps to de-list our common stock. In determining whether to afford a company a cure period prior to commencing suspension or delisting procedures, the NYSE American does analyze all relevant facts including any past history of late filings.  Any de-listing would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase their common stock when they wish to do so. There can be no assurance given that we will be able to continue to satisfy our continued listing requirements and maintain the listing of our common stock on the NYSE American going forward.

The possible issuance of common stock subject to options, restricted stock units and warrants may dilute the interests of stockholders.

As of April 26, 2024, awards for 6,220,623 shares of common stock are outstanding under our equity compensation plans and 1,243,504 shares of common stock remain available for grants under the plans. To the extent that outstanding stock options and warrants are exercised, or additional securities are issued, dilution to the interests of our stockholders may occur. Moreover, the terms upon which we will be able to obtain additional equity capital may be adversely affected since

27

the holders of the outstanding options can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital on terms more favorable to us than those provided in such outstanding options.

We have additional securities available for issuance, which, if issued, could adversely affect the rights of the holders of our common stock.

Our certificate of incorporation authorizes the issuance of 250,000,000 shares of our common stock and 10,000,000 shares of preferred stock. In certain circumstances, the common stock, as well as the awards available for issuance under the incentive plans, can be issued by our Board of Directors, without stockholder approval. Any future issuances of such stock would further dilute the percentage ownership of us held by holders of preferred stock and common stock. Our Board of Directors is authorized to create and issue from time to time, only with stockholder approval, up to an aggregate of 10,000,000 shares of preferred stock of which 8,212,500 have been designated. The authority to designate preferred stock may be used to issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of the common stock or could also be used as a method of determining, delaying or preventing a change of control.

We have never paid dividends and have no plans to pay dividends in the future.

Holders of shares of our common stock are entitled to receive such dividends as may be declared by our Board of Directors. To date, we have paid no cash dividends on our shares of our preferred or common stock and we do not expect to pay cash dividends in the foreseeable future. We intend to retain future earnings, if any, to provide funds for operations of our business. Therefore, any return investors in our preferred or common stock may have will be in the form of appreciation, if any, in the market value of their shares of common stock.

Certain provisions of the General Corporation Law of the State of Delaware, our bylaws and stockholder rights plan may have anti-takeover effects that may make an acquisition of our company by another company more difficult.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination, including mergers and asset sales, with an interested stockholder (generally, a 15% or greater stockholder) for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. The operation of Section 203 may have anti-takeover effects, which could delay, defer or prevent a takeover attempt that a holder of our common stock might consider in its best interest. Certain provisions of our bylaws including the ability of our Board of Directors to fill vacancies on our Board of Directors and advance notice requirements for stockholder proposals and nominations may prevent or frustrate attempts by our stockholders to replace or remove our management. In addition, the Rights issued pursuant to our stockholder rights plan that we implemented, if not redeemed or suspended, could result in the dilution of the stock ownership of a potential hostile acquirer, likely preventing acquisitions that have not been approved by our Board of Directors and therefore discouraging, delaying or preventing a change in control that stockholders may consider favorable.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain types of state actions that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except, in each case for claims arising under the Securities Act, the Exchange Act, or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction.

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, employees, control persons, underwriters, or agents, which may discourage

28

lawsuits against us and our directors, employees, control persons, underwriters, or agents. Additionally, a court could determine that the exclusive forum provision is unenforceable, and our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, or results of operations.

Future sales of our common stock by our existing stockholders could cause our stock price to decline.

On April 26, 2024, we had 36,031,964 shares of our common stock outstanding, all of which are currently eligible for sale in the public market, subject, in certain circumstances to the volume, manner of sale and other limitations under Rule 144 promulgated under the Securities Act. It is conceivable that stockholders may wish to sell some or all of their shares. If our stockholders sell substantial amounts of our common stock in the public market at the same time, the market price of our common stock could decrease significantly due to an imbalance in the supply and demand of our common stock. Even if they do not actually sell the stock, the perception in the public market that our stockholders might sell significant shares of our common stock could also depress the market price of our common stock.

A decline in the price of shares of our common stock might impede our ability to raise capital through the issuance of additional shares of our common stock or other equity securities, and may cause stockholders to lose part or all of their investment in our shares of common stock.

Our shares of common stock are from time to time thinly traded, so stockholders may be unable to sell at or near ask prices or at all if they need to sell shares to raise money or otherwise desire to liquidate their shares.

Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer that has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give stockholders any assurance that a broader or more active public trading market for our common shares will develop or be sustained, or that current trading levels will be sustained.

The shares of common stock offered under any at the market offering that we may engage in, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares that are sold under at-the-market-offerings at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience declines in the value of their shares as a result of share sales made at prices lower than the prices they paid.

Reports published by securities or industry analysts, including projections in those reports that exceed our actual results, could adversely affect our common stock price and trading volume.

Securities research analysts, including those affiliated with our underwriters from prior offerings, establish and publish their own periodic projections for our business. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match securities research analysts’ projections. Similarly, if one or more of the analysts who writes reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business or if one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, our stock price or trading volume could decline.

29

While we expect securities research analyst coverage to continue going forward, if no securities or industry analysts cover us, the trading price for our stock and the trading volume could be adversely affected.

Item 1C. Cybersecurity

We maintain a cyber risk management program designed to identify, assess, manage, mitigate, and respond to cybersecurity threats.

The underlying processes and controls of our cyber risk management program incorporate recognized best practices and standards for cybersecurity and information technology, including the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework (“CSF”). We have an annual assessment performed by a third-party specialist of our cyber risk management program against the NIST CSF. The annual risk assessment identifies, quantifies, and categorizes material cyber risks. In addition, we, in conjunction with the third-party cyber risk management specialists, develop a risk mitigation plan to address such risks, and where necessary, remediate potential vulnerabilities identified through the annual assessment process.

In addition, we maintain policies over areas such as information security, access on/offboarding, and access and account management, to help govern the processes put in place by management designed to protect our IT assets, data, and services from threats and vulnerabilities. We partner with industry recognized cybersecurity providers leveraging third-party technology and expertise. These cybersecurity partners, including consultants and other third-party service providers, are a key part of our cybersecurity risk management strategy and infrastructure and provide services including, maintenance of an IT assets inventory, periodic vulnerability scanning, identity access management controls including restricted access of privileged accounts, network integrity safeguarded by employing web-based software, including endpoint protection, endpoint detection and response, and remote monitoring management on all devices, industry-standard encryption protocols, critical data backups, infrastructure maintenance, incident response, cybersecurity strategy, and cyber risk advisory, assessment and remediation.

Our management team, in conjunction with third-party information technology (“IT”) and cybersecurity service providers, is responsible for oversight and administration of our cyber risk management program, and for informing senior management and other relevant stakeholders regarding the prevention, detection, mitigation, and remediation of cybersecurity incidents. Scorpius Holdings’ management team has prior experience selecting, deploying, and overseeing cybersecurity technologies, initiatives, and processes directly or via selection of strategic third-party partners, and relies on threat intelligence as well as other information obtained from governmental, public, or private sources, including external consultants engaged by us for strategic cyber risk management, advisory and decision making. Our Audit Committee also provides oversight of risks from cybersecurity threats.

As part of its review of the adequacy of our system of internal controls over financial reporting and disclosure controls and procedures, the Audit Committee is specifically responsible for reviewing the adequacy of our computerized information system controls and security related thereof. The cybersecurity stakeholders, including member(s) of management assigned with cybersecurity oversight responsibility and/or third-party consultants providing cyber risk services brief the Audit Committee on cyber vulnerabilities identified through the risk management process, the effectiveness of our cyber risk management program, and the emerging threat landscape and new cyber risks on at least an annual basis. This includes updates on our processes to prevent, detect, and mitigate cybersecurity incidents. In addition, cybersecurity risks are reviewed by our Board of Directors at least annually, as part of our corporate risk oversight processes.

We face risks from cybersecurity threats that could have a material adverse effect on our business, financial condition, results of operations, cash flows or reputation. We acknowledge that the risk of cyber incident is prevalent in the current threat landscape and that a future cyber incident may occur in the normal course of its business. However, prior cybersecurity incidents have not had a material adverse effect on our business, financial condition, results of operations, or cash flows. We proactively seek to detect and investigate unauthorized attempts and attacks against our IT assets, data, and services, and to prevent their occurrence and recurrence where practicable through changes or updates to internal

30

processes and tools and changes or updates to service delivery; however, potential vulnerabilities to known or unknown threats will remain. Further, there is increasing regulation regarding responses to cybersecurity incidents, including reporting to regulators, investors, and additional stakeholders, which could subject us to additional liability and reputational harm. In response to such risks, we have implemented initiatives such as implementation of the cybersecurity risk assessment process and development of an incident response plan. See Item 1A. "Risk Factors" for more information on cybersecurity risks.

Item 2.         Properties

Facilities

Our executive offices are located at 627 Davis Drive, Suite 300, Morrisville, North Carolina 27560.

This lease is set to expire in March 2038. This lease is classified as an operating lease and we recorded a right-of-use asset and corresponding lease liability at commencement.

We believe our existing properties are adequate for our current needs.

Item 3.        Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Company Overview

Scorpius Holdings, Inc. provides process development and biomanufacturing services to support the biomanufacturing needs of third parties who use its biomanufacturing capacity as a fee-for-service model through our subsidiary, Scorpius Biomanufacturing, Inc. (formerly known as Scorpion Biological Services, Inc.). Scorpius couples CGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support cell- and gene-based therapies as well as large molecule biologics using American-made equipment, reagents, and materials. We anticipate the prioritization of Scorpius on American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make us competitive for U.S. government contracts and biodefense assets. We anticipate this will successfully support our expansion within the growing CDMO market.

We commenced operations of the leased San Antonio facility in September 2022. In order to promote efficiency and reduce our reliance on third-party vendors, we have enhanced our in-house development of bioanalytic, process development and manufacturing capabilities and offer such services to third parties for fees. However, there can be no assurance that we will be successful in these new operations.

We intend to meet our financing needs for the operations of the facility through multiple alternatives, including, but not limited to, cash on hand, grant funding and incentives, additional equity financings, debt financings, equipment sales leasebacks, and/or funding from partnerships or collaborations, and potential revenue, if any, from our CDMO biomanufacturing facility.

Recent Financial Developments

On March 9, 2024, we closed the offering contemplated by the Underwriting Agreement that we entered into on March 7, 2024 (the “Agreement”) with ThinkEquity, LLC, as representative of the several underwriters named therein (the “Underwriters”), pursuant to which we issued and sold 10,000,000 shares of our Common Stock at a price of $0.15 per share for net proceeds of $1,235,000.

On January 29, 2024, we entered into a Patent Rights Sale and Assignment Agreement with Kopfkino IP, LLC (“Patent Agreement”). Pursuant to the Patent Agreement, in exchange for $1,000,000, we assigned our right, title and interest in and under the exclusive license agreement it entered into with Shattuck Labs, Inc. (“Shattuck”) in 2016, including our rights to certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us.

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023 (the “Agreement”), with Elusys Holdings, Elusys Holdings purchased from us a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys’ Holdings election and obtaining stockholder approval of the issuance of shares of our common stock upon such conversion. The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of our common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note.

Funding/Liquidity

We have incurred an accumulated deficit of $254.4 million through December 31, 2023. We have incurred negative cash flows from operations since we started our business. We have spent, and expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our planned product development efforts, our clinical trials, and our research and discovery efforts. We have not yet generated significant revenue from operations and do not anticipate that we will generate sufficient revenue from operations in the near term to sustain our operations and therefore we will need to raise capital to sustain our operations.

34

We expect to incur significant expenses and continued losses from operations for the foreseeable future despite our sale of Elusys Therapeutics- and the reduced expenses resulting from such sale. We expect to continue to incur significant expenses as we continue to increase operations at our facility in San Antonio. For the year ended December 31, 2023, we generated approximately $7.0 million in revenue and used cash in operating activities of approximately $31.5 million. To date the revenue generated from our operations in San Antonio has not been sufficient to cover our operating expenses and we have raised money through the equity offering described above, the issuance of the Note and the sale of the Shattuck patent license agreement.

On December 8, 2023, we entered into a Sales Agreement (the “2023 ATM Sales Agreement”) with A.G.P./Alliance Global Partners (the “Sales Agent” or “A.G.P.”) providing for the sale by us of shares of our common stock, from time to time, through or to A.G.P., as sales agent or principal, with certain limitations on the amount of common stock that may be offered and sold by us as set forth in the Sales Agreement (the “Offering”). Under the 2023 ATM Sales Agreement, we issued and sold an aggregate of 137,571 shares of common stock and received net proceeds of $ 0.05 million in December 2023. We issued and sold and aggregate of 19,500 shares of common stock and received net proceeds of $0.01 million in January 2024. Due to the late filing of this Annual Report, we will not be eligible to make sales of shares of common stock under the 2023 ATM Sales Agreement until May 2025.

The audit report  on our consolidated financial statements for the year ended December 31, 2023 contains an explanatory  paragraph have been prepared assuming that we will continue as a going concern. We have suffered recurring losses from operations and not generated significant revenue or positive cash flows from operations. These factors raise substantial doubt about our ability to continue as a going concern. At April 26, 2024, our cash and cash equivalents and short-term investments were $1.4 million. Our current cash, including revenue generated from operations and the proceeds from the Patent Agreement, the Note and the Offering, is anticipated to be sufficient to fund operations only through late May, 2024.

We intend to meet our financing needs through multiple alternatives, including, but not limited to, cash on hand and cash generated from operations, additional equity financings, debt financings, equipment sale leasebacks, and/or funding from partnerships or collaborations and potential revenue, if any, from our planned development and manufacturing facility. However, there can be no assurance that we will be successful in implementing these plans. If we do not raise capital or successfully engage a strategic partner in the next few months, we may be required to delay, reduce, or terminate some or all of our operations, sell some of our assets, cease operations, liquidate our assets or reorganize the Company, or a combination of the foregoing.

CRITICAL ACCOUNTING ESTIMATES

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of our consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as "critical" because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used, which would have resulted in different financial results.

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates based on historical experience and make various assumptions, which management believes to be reasonable

35

under the circumstances, which form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The notes to our audited consolidated financial statements contain a summary of our significant accounting policies. We consider the following accounting policies critical to the understanding of the results of our operations:

● Revenue;

● Deferred revenue;

● Leases;

● Intangible assets;

● Goodwill impairment;

● Income tax;

● Contingent consideration;

● Stock-based compensation; and

● Research and development costs, including clinical and regulatory cost;

Revenue and Deferred Revenue

Our 2023 revenue primarily consisted of product sales revenue of ANTHIM® and process development revenue from our CDMO. Our 2022 revenue primarily consisted of product sales revenue of ANTHIM®. ANTHIM® revenue from Elusys Therapeutics is reported in discontinued operations for both 2023 and 2022. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information. Product sales revenue is recognized when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. Grant revenue is recognized when qualifying costs are incurred and there is reasonable assurance that the conditions of the award have been met for collection. Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an input method by tracking the progress toward completion by measuring inputs to date relative to total estimated inputs needed to satisfy the performance obligation. Under a process development contract, the customer owns the product details and process, which has no alternative use. Each process represents a distinct service that is sold separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, the transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods to a customer. Deferred revenue represent customer deposits for process development services billed and/or received in advance of our fulfillment of performance obligations. Deferred revenue will convert to revenue as we perform our obligations under the contract.

Leases

We determine if an arrangement is, or contains, a lease at inception. Operating and finance leases are included in right-of-use assets and lease liabilities in our consolidated balance sheets, representing our right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. Right-of-use, or ROU, assets and lease liabilities are recognized at commencement based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments. The ROU assets also include any lease payments made and is adjusted for lease modifications. When a modification to a lease occurs, the lease liability and right-of-use asset is remeasured based on the remaining lease payments and incremental borrowing rate as of the effective date of the modification. Lease terms may include options to extend or terminate the lease which are recognized when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease terms. Lease and non-lease components are accounted for as a single lease component.

36

Goodwill and Intangible Assets

Intangible assets represent the fair value assigned to technologies that were acquired from Elusys Therapeutics, which at the time of acquisition have not reached technological feasibility and have no alternative future use. Intangible assets from the acquisition of Pelican were considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. During the third quarter of 2022, Pelican’s intangible asset was fully written-off as the PTX-35 trial has been discontinued. The intangible asset acquired from the acquisition of Elusys Therapeutics is a definite-lived asset comprised of the ANTHIM® formulation. The asset is being amortized over 80 months, which is the approximate life of the patent. During the third quarter of 2023, our activities with regard to the divesture of the Elusys Therapeutics business met the criteria to report within discontinued operations. We evaluated intangible assets and goodwill for impairment under ASC 360-10, Impairment or disposal of long-lived assets and ASC 350, Intangibles—Goodwill and Other. As a result, goodwill was fully impaired by $3.9 million and intangible assets were partially impaired by $2.3 million. These impairments resulted in the carrying value of the discontinued operation asset being less than the fair value and therefore no loss has been recognized upon reclassification of Elusys Therapeutics to discontinued operations. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Intangible assets are tested for impairment on an annual basis, or more frequently if we become aware of any events occurring or changes in circumstances that indicate that the fair value of the assets are less than their carrying amounts. If development is terminated or abandoned, we may have a full or partial impairment charge related to the asset, calculated as the excess of carrying value of the intangible assets over fair value. See Note 9 regarding impairment at December 31, 2023.

We test goodwill and intangible asset impairment each year as of April 1, or more frequently should a significant impairment indicator occur. As part of the impairment test, we may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit, including goodwill, is less than its carrying amount, or if we elect to bypass the qualitative assessment, we would then proceed with the impairment test. The impairment test involves comparing the fair values of the reporting units to their carrying amounts. If the carrying amount of a reporting unit exceeds its fair value, we recognize a goodwill loss in an amount equal to any excess.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows at the reporting unit level using risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration expectations of competitive, business, and economic environments. We also identify similar publicly traded companies and develop a correlation, referred to as a multiple, to apply to the operating results of the reporting units.

Determining the fair value of intangible assets is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows, risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration expectations of competitive, business, and economic environments. The fair value is then compared to the carrying value and if the carrying value exceeds fair value an impairment charge is recognized.

Changes in market demand, fluctuations in the markets in which we operate, the volatility and decline in the worldwide equity markets, and a decline in our market capitalization could unfavorably impact the remaining carrying value of our goodwill and intangible assets, which could have a significant effect on our current and future results of operations and financial position.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which

37

those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with FASB ASC 740, Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations.

Contingent Receivables, Related Party

Contingent receivables, related party are recorded as assets and represent the estimate of fair value of future note payable issuances and royalty earnout payments related to consideration from the divestiture of Elusys Therapeutics, Inc. Contingent receivables, related party are measured at fair value using a probability-weighted income approach utilizing significant unobservable inputs including the probability of achieving each of the potential milestone and royalty payments and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones would result in a significantly higher or lower fair value of these milestones, respectively, and commensurate changes to the associated asset. The contingent receivables, related party are revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Stock-Based Compensation

Calculating stock-based compensation expense requires the input of highly subjective assumptions. The fair value of restricted stock units is estimated based on the closing price of our stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for as they occur. We apply the Black-Scholes-Merton option pricing model to determine the fair value of our stock options awards. Inherent in this model are assumptions related to expected stock-price volatility, expected option life, risk-free interest rate and dividend yield. We use an average historical stock price volatility of our own data. We estimate the expected life of our options using the simplified method. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected life of the options. The dividend rate is based on our historical rate, which we anticipate remaining at zero. We account for forfeitures as they occur. The assumptions used in calculating the fair value of stock options represent our best estimates, however these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and different assumptions are used, the stock-based compensation expense could be materially different in the future.

Research and Development Costs

We expense research and development costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing our developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation, and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of our product candidates, and other expenses relating to the design, development, and testing and enhancement of our product candidates.

RESULTS OF OPERATIONS

Years Ended December 31, 2023 and 2022

Revenues

For the year ended December 31, 2023, we recognized $6.6 million of contract revenue, $0.3 million of National Institutes of Health (“NIH”) grant revenue and $0.1 million of royalty revenue. For the year ended December 31, 2022, revenue consisted of $0.1 million of contract revenue, and $0.3 million of CPRIT grant revenue. The revenue does not reflect any revenue derived from Elusys Therapeutics which was divested in December 2023. The increase in contract revenue is primarily due to execution of process development contracts, a significant portion of which was from one customer for which we no longer anticipate deriving significant revenue.

Cost of revenues

For the year ended December 31, 2023, we recognized $2.7 million of cost of revenues from product sales as compared to $0.1 million for the year ended December 31, 2022. The increase of $2.6 million was due to the cost of executing on process development contracts.

Research and development expense

Research and development expenses for the years ended December 31, 2023 and 2022 were $20.1 million and $20.2 million, respectively. The components of research and development expense are as follows, in millions:

	For the Year's Ended
	December 31,
	2023		2022
Programs
CDMO	$	13.3	$	7.0
HS-110		1.4		0.5
HS-130		—		0.7
PTX-35		1.2		2.6
Other programs		1.2		1.6
Unallocated research and development expenses		3.0		7.8
	$	20.1	$	20.2

● CDMO increased by $6.3 million primarily due the expenses associated with the validation and commissioning of clean rooms, laboratories, equipment, and processes and the hiring of employees in support of contract execution,

● HS-110 increased by $0.9 million primarily due to a decrease in manufacturing expenses and site and investigator fees as the result of the closing of our clinical trials.

● HS-130 expense decreased by $0.7 million primarily due to increased final site and investigator fees as the result of the closing of our clinical trials.

● PTX-35 expense decreased by $1.4 million primarily due to a decrease in site and investigator fees as the result of the closing of our clinical trials.

● Other programs expenses decreased by $0.4 million and include preclinical and final costs associated with the suspension of our non-clinical, and other discovery research programs.

● Unallocated research expenses decreased by $4.8 million primarily from the discontinuation of clinical trials, and elimination of research and development in the North Carolina facility.

39

Selling, general and administrative expenses

Selling, general and administrative (“SGA”) expenses for the years ended December 31, 2023 and 2022 were $26.2 million and $20.1 million, respectively. The increase of $6.1 million was primarily due to increased sales and marketing costs for marketing the Company to the CDMO market space of $2.4 million, an increase in labor for Scorpius to support operations of $1.8 million, an increase in legal, accounting, and other professional expenses to manage the business of $1.8 million, an increase in facilities expenses from the opening of our San Antonio facility of $1.4 million, an increase in depreciation and amortization of $0.8 million due to increased investment in equipment and the amortization of right to use assets, offset by decreases in stock-based compensation of $1.1 million, a decrease in other facility and operation expenses of $0.4 million, a reduced need for outside consultants associated with the build-out of Scorpius of $0.4 million, and a reduction of insurance costs of $0.1 million.

In-process research and development impairment

In-process research and development (“IPR&D”) impairment was $0 and $3.5 million for the years ended December 31, 2023 and 2022, respectively. IPR&D was fully impaired during the third quarter of 2022 as the PTX-35 trial did not progress to Phase 2.

Change in fair value of contingent consideration

We reassess the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. The decrease in the fair value of contingent consideration of $3.3 million for the year ended December 31, 2022 represents the write off of Pelican’s contingent consideration due to the discontinuation of the PTX-35 program. No change in fair value of contingent consideration is associated with current programs in 2023.

Total operating loss

Total operating loss was $42.0 million for the year ended December 31, 2023, compared to $40.2 million for the same period of 2022, representing a difference of $1.8 million. The change was due to $6.1 million of expenses from the build up of operations for the CDMO including sales and marketing, labor costs for supporting personnel, and legal and accounting fees, an additional $2.6 million of additional cost of revenues, partially offset by $0.1 million of reduced research and development expenses, non-recurring IPR&D and change in fair value of contingent consideration of $0.2 million, and $6.6 million of additional revenue compared to the same period in 2022.

Total non-operating loss

Total non-operating loss was $0.3 million for the year ended December 31, 2023 which primarily consisted of $0.8 million of finance lease interest expense, partially offset by $0.5 million of interest and dividends income, and $0.1 million of unrealized gains on short-term investment balances. Total non-operating loss was ($1.4) million for the year ended December 31, 2022 which primarily consisted of $1.7 million of unrealized losses on short-term investment balances, $0.7 million of interest expenses, partially offset by $1.0 million of interest income.

Income tax benefit

Income tax benefit was $0.6 million for the year ended December 31, 2023 compared to $0.2 million for the year ended December 31, 2022. The increase of $0.4 million is primarily due to the recognition of Elusys Therapeutics deferred tax liability.

Net loss from discontinued operations net of tax benefit

Net loss from discontinued operations net of tax benefit was $5.1 million for the year ended December 31, 2023 compared to $2.5 million for the same period of 2022, representing a change of $2.6 million. The change is from impairment of intangible assets of $6.2 million, partially offset by increased revenue of $0.7 million, reduced costs of revenue of $4.1

40

million, net decrease in R&D and SG&A expenses of $0.4 million, a gain on sale of discontinued operations of $1.5 million, and a reduction in other expenses, net of $0.1 million.

Gain on sale of discontinued operations

On December 27, 2023, we completed the sale of all the assets and equity interest of Elusys Therapeutics, Inc. to Elusys Holdings, Inc. for approximately $2.5 million before working capital and escrow adjustments and transaction expenses. Total consideration included $0.5 million of cash received at closing, $0.4 million fair value of a contingent earn-out receivable, related party, and $1.7 million fair value of a contingent consideration receivable, related party, for future payments from Elusys Therapeutics upon the achievement by Elusys Therapeutics of certain financial goals. The gain on the transaction was approximately $1.5 million.

BALANCE SHEET AS OF DECEMBER 31, 2023 AND 2022

Short-term investments. Short-term investments were $2.2 million as of December 31, 2023 compared to $35.8 million as of December 31, 2022. The decrease is primarily due the sale of investments and transferring the cash to fund the Scorpius facility build-out, hiring of employees, validation of facility and processes, wind-down of North Carolina research and development, and other operations.

Grants receivable. Grants receivable was $0 million as of December 31, 2023, and $1.5 million as of December 31, 2022, respectively. The $1.5 million balance represented the remaining balance of funds due from the CPRIT grant. Payment for the full balance was received in April 2023.

Prepaid expenses and other current assets. Prepaid expenses and other current assets were approximately $0.8 million as of December 31, 2023 and $1.5 million as of December 31, 2022. The $0.7 million decrease is primarily attributable to costs related to the close-out process of our PTX-35 clinical trial.

Current assets of discontinued operations. As of December 31, 2022, we had current assets of discontinued operations of approximately $7.9 million. The current assets of discontinued operations are the assets of Elusys Therapeutics which was divested in December 2023.

Property, plant & equipment, net. Property, Plant and Equipment, net was approximately $17.6 million as of December 31, 2023, and $20.4 million as of December 31, 2022. The decrease of $2.8 million is attributed to $4.6 million of depreciation of primarily lab equipment and leasehold improvements partially offset by additions of new lab equipment, computers, and leasehold improvement assets of $1.7 million supporting Scorpius.

Operating and financing lease right-of-use assets. Current and long-term assets related to operating and finance leases were $26.5 million as of December 31, 2023 and $21.2 million as of December 31, 2022. The increase of $5.3 million primarily represents the CDMO microbial building lease taking effect in 2023. These balances are related to our Scorpius CDMO leases, corporate office lease, and equipment leases.

Other assets. Other assets were approximately $0.2 million and $0.3 million as of December 31, 2023 and 2022, respectively. The $0.1 million decrease relates to reimbursement of partial land improvement costs related to the proposed location of the Kansas facility for Scorpius.

Contingent earm-out receivable, related party. As of December 31, 2023, a contingent earn-out receivable, related party of $1.7 million represents the fair value of contingent future royalty payments from Elusys Holdings, Inc. on potential future sales generated by Elusys Therapeutics, Inc., as part of the divestiture agreement.

Non-current assets of discontinued operations. As of December 31, 2022, we had non-current assets of discontinued operations of $12.2 million. The non-current assets of discontinued operations are the assets of Elusys Therapeutics which was divested in December 2023.

41

Accounts payable. Accounts payable was approximately $4.1 million and $4.2 million as of December 31, 2023 and December 31, 2022, respectively. The $0.1 million decrease is due to vendor payments mainly related to ongoing operations of the Scorpius facility.

Deferred revenue. Deferred revenue was $2.4 million and $1.6 million as of December 31, 2023 and December 31, 2022, respectively. This increase of $0.8 million represents proceeds received for Scorpius contracts but for which costs have not been incurred or the conditions of the contracts not yet met.

Accrued expenses and other liabilities. Accrued expenses and other liabilities were approximately $2.2 million at December 31, 2023 compared to $1.9 million at December 31, 2022. The increase of $0.3 million is primarily due to validation and commissioning of the Scorpius facility, sale and marketing for Scorpius, and labor costs for hiring.

Current liabilities of discontinued operations. Current liabilities of discontinued operations was approximately $9.6 million for the year ended December 31, 2022. The current liabilities of discontinued operations are the liabilities of Elusys Therapeutics which was divested in December 2023.

Operating and financing lease liabilities. Current and long-term liabilities related to operating and finance leases were $14.0 million as of December 31, 2023 and $9.3 million as of December 31, 2022. The increase of $4.7 million primarily represents the microbial building lease taking effect in 2023. These balances are related to our Scorpius facility lease, corporate office lease and equipment leases.

Non-current liabilities of discontinued operations. Non-current liabilities of discontinued operations was approximately $5.3 million for the year ended December 31, 2022. The non-current liabilities of discontinued operations are the liabilities of Elusys Therapeutics which was divested in December 2023.

LIQUIDITY AND CAPITAL RESOURCES

Current and Future Financing Needs

Since our inception in June 2008, we have incurred significant losses and we have financed our operations with net proceeds from the private placement of our preferred stock, common stock and debt and more recently the assignment of certain non-core assets pursuant to the terms of the Patent Agreement, the Note and the public offering of our common stock. Since our initial public offering, we have not generated significant revenue from operations and have primarily financed our operations with net proceeds from the public offering of our securities and to a lesser extent, the proceeds from the exercise of warrants. As of December 31, 2023, we had an accumulated deficit of approximately $254.4 million. We had net losses of $46.8 million and $43.9 million for the years ended December 31, 2023 and 2022, respectively. At April 26, 2024, our cash and cash equivalents and short-term investments were $1.4 million. Our current cash, including revenue generated from operations and the proceeds from the Patent Agreement, the Note and the Offering, is anticipated to be sufficient to fund operations only through May 15, 2024 and therefore we need to raise additional funds either through operations or financings.

We will need to raise additional capital. However, the actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include the following:

● our ability to attract customers for our CDMO services and retain current customers

● our ability to timely complete projects within estimated budgets

● the number and scope of our research programs;

● the progress of our research activities;

● the progress of our preclinical and clinical development activities;

● the progress of the development efforts of parties with whom we have entered into research and development agreements;

● our expansion plans and cash needs of any new projects; and

● additional manufacturing facility construction costs and equipment costs.

42

We have based our estimate on assumptions that may prove to be wrong. We may need to obtain additional funds sooner or in greater amounts than we currently anticipate. Potential sources of financing include strategic relationships, public or private sales of our equity or debt and other sources. We may seek to access the public or private equity markets when conditions are favorable due to our long-term capital requirements. We do not have any committed sources of financing at this time, and it is uncertain whether additional funding will be available when we need it on terms that will be acceptable to us, or at all. In addition, until May 2025, due to the late filing of this Annual Report, we will not be eligible to make sales of securities utilizing a registration statement on Form S-3 and therefore we will be unable to sell shares of common stock through any at-the-market offering sales agreement. If we raise funds by selling additional shares of common stock or other securities convertible into common stock, the ownership interest of our existing stockholders will be diluted. If we are not able to obtain financing when needed, we may be unable to carry out our business plan. As a result, we may have to significantly limit our operations and our business, financial condition and results of operations would be materially harmed. If we do not raise capital or successfully engage a strategic partner in the near term, we may be required to delay, reduce, or terminate some or all of our operations, sell some of our assets, cease operations, liquidate our assets or reorganize the Company, or a combination of the foregoing.

Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, our operations. These factors raise substantial doubt about our ability to continue as a going concern for one year after the financial statements are issued. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which include sales of our common stock under at-the-market offerings, if available, debt financings, equipment sales leasebacks, collaborations and other funding transactions. This is based on our current estimates, and we could use our available capital resources sooner than we currently expect. We will need to generate significant revenues to achieve profitability, and we may never do so.  As of December 31, 2023, we had approximately $2.4 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

Cash Flows

Operating activities. Net cash used in operating activities was $31.5 million during the year December 31, 2023 compared to $5.7 million used during the same period in 2022. The increase of $25.8 million consisted of an additional net loss of $3.0 million and $30.6 million of changes in working capital, partially offset by an increase of $7.7 million in adjustments for non-cash items. The additional net loss of $3.0 million was primarily attributed to the increased CDMO operating costs supporting validation and commissioning of the facilities, hiring costs, and sales and marketing efforts. The changes in working capital of $30.6 million, consisted of a change in contract receivables of $24.5 million, a change in other assets of $12.6 million, a change in inventory of $6.7 million, a change in accounts payable, accrued expenses, and deferred revenue of $3.0 million, partially offset by a change in right-of-use assets of $11.9 million and a change in accounts receivable of $0.3 million, a change in prepaid expenses and other expenses of $2.6 million, a change in grant receivable of $1.7 million, a change in income tax receivable of $0.2 million, and a change in deposits of $0.1 million.

Investing activities. Net cash provided by investing activities was $32.2 million during the year ended December 31, 2023 compared to $11.0 million used during the same period in 2022. The increase of $21.2 million was primarily due to a reduction in purchases of equipment of $17.9 million, a reduction in contingent consideration payments of $22.8 million, partially offset by reduced net sales of short-term investments of $17.0 million, and non-recurring business acquisition payments, net of current year sale proceeds of $2.5 million.

Financing activities. Net cash used in financing activities was $9.0 million during the year ended December 31, 2023 compared to $4.9 million used during the same period in 2022. The increase of $4.1 million was primarily due to an

43

increase of $2.4 million of additional principal payments against finance leases and an increase in payments of contingent consideration of $1.7 million.

Item 9A.      Controls and Procedures

Disclosure Controls and Procedures

Under the direction and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2023. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in its periodic reports with the Securities and Exchange Commission is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and regulations, and that such information is accumulated and communicated to management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide a reasonable level of assurance of reaching its desired disclosure control objectives.

Our Chief Executive Officer and Chief Financial Officer has concluded that, due to the material weaknesses described below, our disclosure controls and procedures were not effective as of December 31, 2023.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a process designed by, or under the supervision of the principal executive officer and principal financial officer and implemented by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including the Chief Executive and Principal Financial Officer, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2023 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or the COSO Framework. Management’s assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls. Our Chief Executive and Financial Officer concluded that as of such date, our internal controls over financial reporting were not effective.

44

Material Weaknesses in Internal Control Over Financial Reporting

A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Our management concluded that the following material weaknesses existed as of December 31, 2023:

● We identified ineffective information technology general controls in the areas of user access and segregation of duties related to certain information technology systems that support our financial reporting process. As a result, certain activity level controls were also deemed to be ineffective that are dependent on information derived from these information technology systems.

● In March 2023, we determined that we had made certain errors in the manner in which we recognized the deferred tax asset valuation allowance related to the acquisition of Elusys Therapeutics with the result that net loss had been overstated in our quarterly filings for the periods ending June 30, 2022 through September 30, 2022. As a result, we determined that there were material errors in the financial statements that required a restatement of our Forms 10-Q for the quarterly periods ended June 30, 2022 through September 30, 2022. This was due to the inadequate design and implementation of controls to evaluate and monitor the accounting for income taxes.

● We identified a material weakness related to the ineffective design of certain management review controls across a significant portion of the Company’s financial statement areas, particularly with regard to the precision of the review and evidence of review procedures performed.

● We identified a material weakness related to the ineffective design and implementation of controls around process development revenue recognition, specifically, controls over the review of labor hours incurred and expected to be incurred in satisfaction of our performance obligations.

Remediation of Material Weaknesses

In order to remediate these material weaknesses, we will change certain control activities over financial reporting to include, but are not limited to, the following: (i) evaluating and implementing enhanced process controls around user access management and segregation of duties, (ii) expanding the documentation over user access and system controls and enhancing the level of evidence maintained in management review controls and (iii) enhancing the design of existing controls and are implementing new controls over the accounting, processing, and recording of income tax and revenue.

We are committed to maintaining a strong internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the material weaknesses are remediated as soon as possible.

Notwithstanding the material weaknesses described above, management has concluded that the consolidated financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

Changes in Internal Control over Financial Reporting

Other than as described above, there have been no other changes in our internal control over financial reporting that have occurred during the quarter ended December 31, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B.      Other Information

During the three months ended December 31, 2023, no director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

Committees of the Board of Directors

The Board of Directors has a standing Audit Committee, Compensation Committee, and Nominating and Governance Committee. The following table shows the directors who are currently members or Chairman of each of these committees.

* Dr. Prendergast serves as our independent Lead Director.

Director Independence

Our common stock is listed on the NYSE American. Under the rules of NYSE American, independent directors must comprise a majority of a listed company’s board of directors and all members of our audit, compensation and nominating and governance committees must be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. Under the rules of the NYSE American, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered to be independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

Our Board undertook a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships, our Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast, representing three of our four directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of the NYSE American. In making this determination, our Board considered the relationships that

48

each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. We intend to comply with the other independence requirements for committees within the time periods specified above.

Audit Committee

Dr. Monahan, Mr. Smith, and Dr. Prendergast currently serve as members of the Audit Committee, with Mr. Smith serving as the chair. The Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast are each “independent” in accordance with the NYSE American definition of independence and each is an “audit committee financial expert”, as defined by the SEC regulations, and each has the related financial management expertise within the meaning of the NYSE American rules. The primary purpose of the Audit Committee is to act on behalf of the Board of Directors in its oversight of all material aspects of our accounting and financial reporting processes, internal controls and audit functions, including our compliance with Section 404 of the Sarbanes-Oxley Act of 2002. Pursuant to its charter, our Audit Committee reviews on an on-going basis for potential conflicts of interest, and approves if appropriate, all our “Related Party Transactions.” For purposes of the Audit Committee Charter, “Related Party Transactions” shall mean those transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404. In addition, the Audit Committee reviews, acts on and reports to the Board of Directors with respect to various auditing and accounting matters, including the selection of the Company’s independent registered public accounting firm, the scope of the annual audits, fees to be paid to the independent registered public accounting firm, the performance of the Company’s independent registered public accounting firm and the accounting practices of the Company and the Company’s internal controls and legal compliance functions. The Committee also reviews, prior to publication, our quarterly earnings releases and our reports to the Securities and Exchange Commission on Forms 10-K and 10-Q. The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on the Company’s website at www.scorpiusbiologics.com. The charter describes the nature and scope of responsibilities of the Audit Committee.

Compensation Committee

Our Compensation Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast, each of whom is deemed to be independent in accordance with the NYSE American definition of independence. Dr. Monahan serves as the chair of the Compensation Committee. Members of the Compensation Committee must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. This Committee determines, approves, and reports to the Board of Directors on all elements of compensation of our executive officers. The Compensation Committee also has the power to prescribe, amend, and rescind rules relating to our stock incentive plans, to recommend the grant of options and other awards under the stock incentive plans, and to interpret the stock incentive plans.

Our Compensation Committee annually reviews the compensation program for our Chief Executive Officer and other members of senior management and then makes recommendations to the full board for determination. In each case, the Committee takes into account the results achieved by the executive, his or her future potential, and his or her scope of responsibilities and experience. During our fiscal year ended December 31, 2023, the Compensation Committee evaluated the performance of our executives and considered the compensation levels and equity programs at comparable companies and related industries and the analysis of its outside consultant before it made its compensation recommendations to the full board, including recommendations regarding salary increases, awards of cash bonuses and awards of stock options.

The Compensation Committee administers our equity incentive plans, including review and recommendation of long-term incentive compensation for each executive, director and employee, including grants of stock options. The Compensation Committee believes that this long-term incentive compensation aligns the interests of our executives with those of our stockholders and furthers executive retention.

The Compensation Committee also reviews and recommends to the Board of Directors appropriate director compensation programs for service as directors, committee chairs and committee members.

The Compensation Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.scorpiusbiologics.com.

49

Nominating and Governance Committee

The Nominating and Governance Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast, with Mr. Smith serving as the chair.

The functions performed by the Nominating and Governance Committee include:

● recommending to the Board of Directors individuals for appointment to vacancies on any committee of the Board of Directors;

● recommending to the Board of Directors regarding any changes to the size of the Board of Directors or any committee;

● reporting to the Board of Directors on a regular basis; and

● performing any other duties or responsibilities expressly delegated to the committee by the Board of Directors relating to board or committee members.

Candidates for director should have certain minimum qualifications, including the ability to understand basic financial statements, being over 21 years of age, having relevant business experience (taking into account the business experience of the other directors), and having high moral character. The Nominating and Governance Committee retains the right to modify these minimum qualifications from time to time.

In evaluating an incumbent director whose term of office is set to expire, the Nominating and Governance Committee reviews such director’s overall service to the Company during such director’s term, including the number of meetings attended, level of participation, quality of performance, and any transactions with the Company engaged in by such director during his term.

When selecting a new director nominee, the Nominating and Governance Committee first determines whether the nominee must be independent for NYSE American purposes or whether the candidate must qualify as an “audit committee financial expert.” The Nominating and Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm to assist in the identification of qualified director candidates. The Nominating and Governance Committee also will consider nominees recommended by our stockholders. The Nominating and Governance Committee does not distinguish between nominees recommended by our stockholders and those recommended by other parties. The Nominating and Governance Committee evaluates the suitability of potential nominees, taking into account the current board composition, including expertise, diversity and the balance of inside and independent directors. The Nominating and Governance Committee endeavors to establish a diversity of background and experience in a number of areas of core competency, including business judgment, management, accounting, finance, knowledge of our industry, strategic vision, research and development and other areas relevant to our business.

In considering any person recommended by one of our stockholders, the Nominating and Governance Committee will look for the same qualifications that it looks for in any other person that it is considering for a position on the Board of Directors. The Nominating and Governance Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.scorpiusbiologics.com.

Ad Hoc Committees

From time to time we establish ad hoc committees to address particular matters. In April 2023, we formed a special committee comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast to evaluate strategic opportunities.

Board Leadership Structure

Mr. Wolf, the Company’s Chief Executive Officer, also serves as Chairman of the Board of Directors. We have a separate, independent Lead Director. Although we do not have a formal policy addressing the topic, we believe that when the Chairman of the Board is an employee of the Company or otherwise not independent, it is important to have a separate Lead Director, who is an independent director.

50

Dr. Prendergast serves as the Lead Director. In that role, he presides over the Board’s executive sessions, during which our independent directors meet without management, and he serves as the principal liaison between management and the independent directors of the Board. The Lead Director also:

● confers with the Chairman of the Board regarding Board meeting agenda;

● chairs meetings of the independent directors including, where appropriate, setting the agenda and briefing the Chairman of the Board on issues discussed during the meeting;

● oversees the annual performance evaluation of the CEO;

● consults with the Nominating and Governance Committee and the Chairman of the Board regarding assignment of Board members to various committees; and

● performs such other functions as the Board may require.

We believe the combination of Mr. Wolf as our Chairman of the Board and an independent director as our Lead Director is an effective structure for our company. The division of duties and the additional avenues of communication between the Board and our management associated with this structure provide the basis for the proper functioning of our Board and its oversight of management.

Risk Oversight

The Board has an active role, as a whole and also at the committee level, in overseeing management of our company’s risks. The Board regularly reviews information regarding our company’s strategy, finances and operations, as well as the risks associated with each. The Audit Committee is responsible for oversight of Company risks relating to accounting matters, financial reporting, internal controls and legal and regulatory compliance. The Audit Committee undertakes, at least annually, a review to evaluate these risks. The members then meet separately with management responsible for such area, including our Chief Financial Officer, and report to the Audit Committee on any matters identified during such discussions with management. In addition, the Compensation Committee considers risks related to the attraction and retention of talent as well as risks relating to the design of compensation programs and arrangements. In addition, the Nominating and Governance Committee manages risks associated with the independence of the Board. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. The full Board considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their respective areas of responsibility.

Code of Business Conduct and Ethics

We have long maintained a Code of Business Conduct and Ethics (the “Code”) that is applicable to all of our directors, officers and employees. We undertake to provide a printed copy of these codes free of charge to any person who requests. Any such request should be sent to our principal executive offices attention: Corporate Secretary. The Code is posted on our website at www.scorpiusbiologics.com. We intend to disclose any changes in or waivers from the Code on our website at www.scorpiusbiologics.com. The information on the website is not and should not be considered part of this Annual Report and is not incorporated by reference in this Annual Report.

Item 11.        Executive Compensation

We are a “smaller reporting company” and the following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program, the Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2022 executive compensation program for our named executive officers.

51

Set forth below is the compensation paid or accrued to our Named Executive Officers during the years ended December 31, 2023 and 2022:

Narrative Disclosure to Summary Compensation Table

Overview of Our Compensation Program

A. Philosophy and Objectives

Our primary objective with respect to executive compensation is to design compensation programs that will align executives’ compensation with our overall business strategies for the creation of stockholder value and attract, motivate and retain highly qualified executives.

Our executive compensation program is based on the following philosophies and objectives:

● Compensation Should Align with Stockholders’ Interests — The Compensation Committee and our Board believes that executives’ interests should be aligned with those of the stockholders.

● Compensation is Competitive — The Compensation Committee and Board seek to provide a total compensation package that attracts, motivates and retains the executive talent that we need in order to maximize the return to stockholders and execute our operational and scientific strategy. To accomplish this objective, executive compensation is reviewed annually to ensure that compensation levels are competitive and reasonable in relation to comparable companies with which we compete for talent.

● Compensation Motivates and Rewards the Achievement of Goals — Our executive compensation program is designed to appropriately reward both individual and collective performance that meets and exceeds our annual and long-term strategic and operational goals.

We seek to achieve these objectives through three key compensation elements:

● Base Salaries Base salary is intended to provide our executive officers with basic non-variable compensation that is competitive considering each officer’s responsibilities, experience and performance, and our financial resources;

● Discretionary Incentive Bonus — The Compensation Committee’s goal in granting incentive bonuses is typically to tie a portion of each executive officer’s compensation to our operating performance and to the officer’s individual contributions to that performance; and

52

● Long-Term Equity Incentive Awards The goal of long-term equity incentive compensation is to align the interests of the executive officers with our stockholders and to provide the officers with a long-term incentive to manage from the perspective of an owner with an equity stake in the business. It is the belief of the Compensation Committee that stock and other equity-based awards directly motivate an executive to maximize long-term shareholder value.

In order to enhance the Compensation Committee’s ability to carry out its responsibilities effectively, as well as maintain strong links between executive pay and performance, the Compensation Committee reviews compensation information for each Named Executive Officer, which includes the following information:

● the annual compensation and benefit values that are being offered to each executive;

● the value of all outstanding equity awards; and

● discussions with our Chairman, Chief Executive Officer and other senior management in connection with compensation matters, as well as compensation consultants and other advisors from time to time.

B. Compensation Administration

Roles and Responsibilities of the Compensation Committee

The primary purpose of the Compensation Committee is to conduct reviews of our general executive compensation policies and strategies and oversee and evaluate our overall compensation structure and programs. The Compensation Committee confirmed that total compensation paid to our Named Executive Officers during the year ended December 31, 2023, in light of our cash restraints and available equity awards was reasonable and competitive. The following were our Named Executive Officers for the year ended December 31, 2023: Jeffrey Wolf, our Chief Executive Officer and William L.

Additional information regarding the Compensation Committee’s responsibilities is set forth in its charter, which is posted on our website at www.scorpiusbiologics.com.

Use of Compensation Consultant

The Compensation Committee has the authority under its charter to retain compensation consultants to assist in carrying out its responsibilities. The Compensation Committee has from time to time retained consultants to provide independent advice on executive officer and director compensation.  In December 2022, the Compensation Committee retained Meridian Compensation Partners, LLC (“Meridian”) as its independent compensation advisor. Meridian report to the Chairman of the Compensation Committee and had direct access to the other members of the Compensation Committee. The Compensation Committee assessed the independence of Meridian pursuant to SEC rules and in accordance with NYSE American listing standards, noting that Meridian does not provide any services to the Company other than advice to the Compensation Committee regarding executive officer and director compensation, and concluded that no conflict of interest exists.

During 2022, Meridian principally provided analysis, advice and recommendations regarding named executive officer and non-employee director compensation. Meridian conducted a comprehensive assessment of our Named Executive Officer’s pay program relative to a peer group of 17 similarly-situated public companies that were pre-revenue cancer therapeutics companies with market capitalizations between $150 million and $1.6 billion. The elements of the Named Executive Officer’s pay programs assessed against peer group practices included: (1) base salary, (2) target annual incentives (bonuses), (3) target total cash compensation, (4) long-term incentives and (5) target total direct compensation. In addition, Meridian also provided an analysis of our pay mix relative to peer group practices. Meridian’s assessment included our Chief Executive Officer and Chief Financial Officer. In 2022, the Compensation Committee evaluated Meridian’s reports and, as they considered appropriate to achieve the best interests of the Company and its stockholders, made determinations related to 2022 cash bonuses and long-term equity awards based, in part, on Meridian’s reports.

The Compensation Committee set base salaries in December 2022, in part, on Meridian’s 2022 advice. The Compensation Committee did not retain Meridian or any other outside compensation consultant during 2023 as a decision was made not to pay cash bonuses or issue long-term equity awards.

Role of the Chief Executive Officer

Our Chief Executive Officer, Mr. Wolf, makes recommendations to the Compensation Committee regarding the compensation of our other named executive officers. Mr. Wolf does not participate in any discussions or processes concerning his own compensation.

Compensation Committee Consideration of Shareholder Advisory Votes

Based upon the vote of the Company’s shareholders at the 2019 annual meeting of stockholders, the Company currently provides its shareholders with the opportunity to cast an advisory vote on executive compensation (a “say-on-pay proposal”) once every three (3) years. At our annual meeting of stockholders held on September 15, 2022, we submitted our executive compensation program that covers our Named Executive Officers to our stockholders for a nonbinding advisory vote. Our executive compensation program did not receive the support of holders of a majority of the shares that voted on this proposal at the annual meeting of stockholders. In response to the vote, with respect to 2022 compensation, we did not grant Mr. Wolf shares of restricted stock which in prior years resulted in a tax being required to be paid upon grant and resulted in a special bonus being granted to Mr. Wolf to cover taxes and instead we granted him options, which are not taxed upon grant and therefore we did not issue a special bonus to cover taxes. In 2023, the Company determined not to (i) pay cash bonuses in light of cash restraints or (ii) issue long-term equity awards due to the limited number of shares available for issuance under the 2018 Stock Incentive Plan.

C. Competitive Considerations

In making compensation decisions with respect to each element of compensation for our Named Executive Officers, the Compensation Committee believes that it is important to be informed as to the competitive market practices at similarly

54

situated public companies. In setting 2022 target total direct compensation levels for our Named Executive Officers, the Compensation Committee relied in part on reports prepared by Meridian effective December 7, 2022. The Compensation Committee set 2023 base salary based, in part, on Meridian’s 2022 advice. In 2023, the Compensation Committee determined not to pay any cash bonuses or issue long-term equity awards.

D. Components of Compensation

The allocation between cash and non-cash named executive officer compensation is influenced by subjective and objective factors considered by the Compensation Committee and is intended to reflect the Compensation Committee’s determination of the appropriate compensation mix among base pay, annual cash incentives and long-term equity incentives for each Named Executive Officers.

1. Base Salaries

We provide our Named Executive Officers a competitive level base salary commensurate with their position, responsibilities and experience. In setting the base salary, the Compensation Committee considers a number of factors including, peer group market data, our company performance, our financial resources, and each Named Executive Officer’s role and responsibilities, experience and individual performance. We design base pay to be competitive in attracting and retaining top talent.

Initial base salaries for the Named Executive Officers were set by their initial respective employment contracts and are reviewed annually by the Compensation Committee. In December 2022, the Compensation Committee reviewed Meridian’s reports and determined to increase base salary for our Chief Executive Officer based solely on a cost of living adjustment.  In December 2022, the Compensation Committee determined that our Chief Financial Officer’s base salary levels were below market practice of our peer group; therefore his base salary was increased to $375,000. There have been no additional increases in base salary. The base salaries for our current Named Executive Officers for 2022, 2023, and 2024 are set forth below:

Named Executive Officer	Base Salary 2022		Base Salary 2023		Base Salary 2024
Jeffrey Wolf, Chief Executive Officer	$	561,600	$	575,000	$	575,000
William L. Ostrander, Chief Financial Officer	$	350,000	$	375,000	$	375,000

2. Bonuses

Each of our Named Executive Officer’s employment agreements provide that such officer is eligible for an annual cash bonus in the discretion of the Compensation Committee. In determining whether to award a cash bonus, the Compensation Committee considers the Company’s performance during the year and the executive’s contribution thereto. Focusing on oindividual performance enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation.

For 2023, the Compensation Committee determined not to pay any bonuses to our Named Executive Officers due to cash restraints. For 2022, the Compensation Committee recommended to the full Board of Directors the following bonus payouts to our Named Executive Officers:

● Jeffrey Wolf bonus. The Board approved the Compensation Committee’s recommendation that Mr. Wolf receive a $281,000 cash bonus (50% of gross salary which was his then target bonus percentage).

● William Ostrander bonus. The Board approved the Compensation Committee’s recommendation that Mr. Ostrander receive a $122,500 cash bonus (35% of gross base salary which was his then target bonus percentage).

The employment agreement with Jeffrey Wolf that was in effect during 2022 and 2023 provided that he was eligible for a cash performance bonus of up to fifty percent (50%) of his base salary which was increased to fifty five (55%) in December 2022 in the sole discretion of the Board of Directors, with the actual amount of any such bonus increased or decreased in

55

the sole discretion of the Board of Directors. William L. Ostrander’s employment agreement that was in effect for 2022 and 2023 provided for an annual bonus of up to thirty-five percent (35%) of his base salary which was increased to forty (40%) in December 2022 in the sole discretion of the Board of Directors, with the actual amount of any such bonus increased or decreased in the sole discretion of the Board of Directors.

3. Long-Term Incentives

Our Compensation Committee believes that equity awards are a key component of our executive compensation program. Long-term equity awards incentivize executives to deliver long-term shareholder value, while also providing a retention vehicle for our executives.

In 2023, it was determined that no equity-based compensation would be issued to the Named Executive Officers based upon the limited number of awards available for grant under the 2018 Stock Incentive Plan. We intend to solicit stockholder approval to increase the number of shares available for issuance under our 2018 Stock Incentive Plan. Assuming we obtain such shareholder approval, we intend to issue equity awards for 2023 performance.

In 2022 the Compensation Committee determined the size of equity awards granted to the Named Executive Officers based on the following factors: accounting impact, peer group market data, our company performance and each Named Executive Officer’s position, role and responsibilities, experience, tenure, individual performance and pro forma percent ownership. In addition, the Compensation Committee considered that there was a lack of realizable value from their prior awards since substantially all of the prior awards were of significant low value and/or underwater or held low value. The Compensation Committee also sought to better align the Chief Executive Officer’s equity ownership interest in our company with that of other chief executive officers of our peer group companies. The Compensation Committee determined in December 2022 to grant a combination of options to the Chief Executive Officer and the Chief Financial Officer.

On December 7, 2022, Mr. Wolf and Mr. Ostrander were granted a ten-year option to purchase 2,843,137 and 490,196 shares of our common stock respectively of which one third vests on January 2023 and the balance vests pro-rata over 36 months.

On August 2, 2021, the Board of Directors adopted the Heat Biologics, Inc. 2021 Subsidiaries Stock Incentive Plan (the “SSIP”). The SSIP is designed to compensate employees of our subsidiaries based on their responsibilities and for their contributions to the successful achievement of certain corporate goals and objectives of such subsidiaries and to share the success and risks of such subsidiaries based upon achievement of business goals.  In addition, in August we issued to Mr. Wolf options under the SSIP to purchase 10,526, 10,638, 10,526 and 10,526 shares of common stock of Skunkworx, Scorpius, Abacus, and Blackhawk, respectively and we issued Mr. Ostrander 2,127 shares of common stock of Scorpius, all subject to forfeiture if the Subsidiary Plan was not approved by our stockholders at our annual meeting so stockholders.  At our Annual Meeting of Stockholders held on September 15, 2021, the SSIP was approved by our stockholders. Skunkworx, Scorpius, Abacus, and Blackhawk currently have 200,100, 200,100, 200,000 and 200,000 shares outstanding, respectively.

The Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about our company that has not been publicly disclosed. Option grants are effective on the date the award determination is made by the Compensation Committee, and the exercise price of options is the closing market price of our common stock on the business day of the grant or, if the grant is made on a weekend or holiday, on the prior business day.

Clawback Policy

The Board has adopted a clawback policy which requires the clawback of erroneously awarded incentive-based compensation of past or current executive officers awarded during the three full fiscal years preceding the date on which the issuer is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the federal securities laws. There is no fault or misconduct required to trigger a clawback.

56

The Compensation Committee shall determine, in its sole discretion, the timing and method for promptly recouping such erroneously awarded compensation, which may include without limitation: (a) seeking reimbursement of all or part of any cash or equity-based award, (b) cancelling prior cash or equity-based awards, whether vested or unvested or paid or unpaid, (c) cancelling or offsetting against any planned future cash or equity-based awards, (d) forfeiture of deferred compensation, subject to compliance with Section 409A of the Internal Revenue Code and the regulations promulgated thereunder, and (e) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Compensation Committee may affect recovery under this policy from any amount otherwise payable to the executive officer, including amounts payable to such individual under any otherwise applicable Company plan or program, including base salary, bonuses or commissions and compensation previously deferred by the executive officer.

The Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about our company that has not been publicly disclosed. Option grants are effective on the date the award determination is made by the Compensation Committee, and the exercise price of options is the closing market price of our common stock on the business day of the grant or, if the grant is made on a weekend or holiday, on the prior business day.

The following is a summary of transactions since January 1, 2022 to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors or beneficial holders of more than five percent of our capital stock had or will have a direct or indirect material interest, other than compensation arrangements which are described under the sections of this Annual Report entitled Part III, Item 10. “Directors, Executive Officers and Corporate Governance—Director Compensation” and Part III, Item 11. “Executive Compensation:”

Compensation paid to our executive officers during 2023 and 2022 and equity awards granted to our executive officers and directors during 2021, 2022, 2023 and payments due to interests in Pelican, are disclosed under the sections of this Annual Report on Form 10-K entitled Part III, Item 10. “Directors, Executive Officers and Corporate Governance—2022 Director Compensation” and Part III, Item 11. “Executive Compensation” and Note 4 to the Company's audited consolidated financial statements for the years ended December 31, 2023 and 2022 “Acquisition of Pelican Therapeutics.”

On December 20, 2021, we entered into the Merger Agreement with Merger Sub, Elusys Therapeutics and Fortis Advisors LLC pursuant to which we acquired Elusys Therapeutics through the Merger. Elusys Therapeutics was formed in 1998 by Jeff Wolf, our President, Chief Executive Officer and Chairman of the Board of Directors, who was a director of Elusys Therapeutics and directly and through affiliated entities owns approximately 1.2% of the outstanding stock of Elusys Therapeutics, in the form of common stock, which is subordinate in terms of distributions to the Elusys preferred stock. However, pursuant to the terms governing the Elusys Therapeutics preferred stock, the preferred stockholders of Elusys Therapeutics will receive all of the initial $5 million of Merger Consideration and all of the net payments from the $31 million of revenues related to fulfillment of the existing SNS contract. While the amount of earn out payments, if any, to be made over the 12 year period following closing is very uncertain, it also presently seems likely that most if not all of

61

such payments will also be paid to the preferred stockholders of Elusys Therapeutics under the terms of such preferred stock. See” Business Recent Developments” for a more complete description of the Merger Agreement.

Indemnification agreements

Our third amended and restated certificate of incorporation contains provisions limiting the liability of directors and our second amended and restated bylaws provide that we will indemnify each of our directors to the fullest extent permitted under Delaware law. In addition, we have entered and expect to continue to enter into agreements to indemnify our directors.

The Divestiture of Elusys Therapeutics

On December 27, 2023, pursuant to that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023 (the “Agreement”), that we entered into with  Elusys Holdings Inc., a Delaware corporation (“Buyer”), a company controlled by our Chairman, Chief Executive Officer and President, Jeffrey Wolf, we completed the Transaction described under Business “the Divestiture of Elusys Therapeutics, Inc.”. See-Part I-Item 1-"Business - The Divestiture of Elusys Therapeutics, Inc.“

Shared Services Agreement

In connection with the Divestiture Transaction, on the date of Closing we entered into a shared services agreement (the “Shared Services Agreement”) described below.

In consideration for such services, the Buyer will pay fees to us for the services provided, and those fees will generally be in amounts intended to allow us to recover all of its direct and indirect costs incurred in providing those services. We will charge the Buyer a fee for services performed by (i) our employees which shall be a percentage of each employee’s base salary based upon an allocation of their business time spent providing such services and (ii) third parties, the fees charged by such third parties. Buyer will also pay us for general and administrative expenses incurred by us attributable to both the operation of the Buyer and us (other than the provision of the services performed by us employees) and the provision of the shared services.

Note issued to Elusys Holdings

On January 26, 2024 we issued to Elusys Holdings, Inc., an entity controlled by Jeff Wolf (“Elusys Holdings”), a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys Holdings’ election and obtaining stockholder approval of the issuance of shares of our common stock upon such conversion. The Note bears interest at a rate of 1% per annum, mature on the one-year anniversary of its issuance and convert into shares of our common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is equal to $0.39109 (which was 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023). Based upon a conversion price of $0.39109, which is 110% of the VWAP of our common stock for the seven trading days prior to December 11, 2023, upon conversion of the Note (exclusive of interest), Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note.

Independence of the Board of Directors

The Board of Directors undertook a review of the independence of the members of the Board of Directors and considered whether any director has a material relationship with our company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, the Board of Directors has determined that all of our current directors, except Mr. Wolf, due to his position as President and Chief Executive Officer of our company, are “independent” as that term is defined under the rules of NYSE American. As a result, Dr. Monahan, Dr. Prendergast and Mr. Smith are deemed to be “independent” as that term is defined under the rules of NYSE American. See the section of this Annual Report entitled “Director Independence” in “Item 10. Directors, Executive Officers and Corporate Governance.”

Item 14.        Principal Accountant Fees and Services

Independent Registered Public Accounting Firm Fees and Services

The following table sets forth the aggregate fees including expenses billed to us for the years ended December 31, 2023 and 2022 by BDO USA, P.C. (f/k/a BDO USA, LLP).

	December 31,		December 31,
	2023		2022
Audit fees and expenses (1)	$	702,600	$	605,349

(1) Audit fees and expenses were for professional services rendered for the audit and reviews of the consolidated financial statements of the Company, professional services rendered for issuance of consents and assistance with review of documents filed with the SEC.

The Audit Committee has adopted procedures for pre-approving all audit and non-audit services provided by the independent registered public accounting firm, including the fees and terms of such services. These procedures include reviewing detailed back-up documentation for audit and permitted non-audit services. The documentation includes a description of, and a budgeted amount for, particular categories of non-audit services that are recurring in nature and therefore anticipated at the time that the budget is submitted. Audit Committee approval is required to exceed the pre-approved amount for a particular category of non-audit services and to engage the independent registered public accounting firm for any non-audit services not included in those pre-approved amounts. For both types of pre-approval, the Audit Committee considers whether such services are consistent with the rules on auditor independence promulgated by the SEC and the PCAOB. The Audit Committee also considers whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, based on such reasons as the auditor’s familiarity with our business, people, culture, accounting systems, risk profile, and whether the services enhance our ability to manage or control risks, and improve audit quality. The Audit Committee may form and delegate pre-approval authority to subcommittees consisting of one or more members of the Audit Committee, and such subcommittees must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. All of the services provided by the independent registered public accounting firm were pre-approved by the Audit Committee.

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors

Scorpius Holdings, Inc.

Morrisville, North Carolina

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Scorpius Holdings, Inc. (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the consolidated financial statements, the Company has suffered recurring losses from operations and has not generated significant revenue or positive cash flows from operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

F-2

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Process Development Revenue Recognition – Estimated Labor Hours to Complete

As described in Notes 3 and 12 to the Company’s consolidated financial statements, the Company recognized $6.6 million in process development revenue for the year ended December 31, 2023. Process development revenue is recognized over time utilizing an input method by tracking the progress toward completion based on the ratio of actual labor hours incurred to date to the Company’s total estimated labor hours to complete.

We identified the total estimated labor hours to complete certain process development revenue contracts as a critical audit matter. The determination of the total estimated labor hours and progress toward completion requires management to make significant estimates. Changes in the total estimated labor hours can have a significant impact on the revenue recognized each period. Auditing these estimates involved especially challenging auditor judgment in evaluating the reasonableness of management’s estimates over the duration of these contracts.

The primary procedures we performed to address this critical audit matter included:

● Assessing the reasonableness of the total estimated remaining labor hours used by the Company in its progress toward completion for certain contracts by:

● Performing inquiries with project managers to assess the nature of activities to complete the project.

● Performing a retrospective review of progress towards completion by comparing to actual labor hours incurred after year-end and investigating variances (if any).

● Obtaining and examining agreements for certain revenue transactions to verify they were appropriately included in management’s estimates of the progress towards completion.

(“Elusys”)  to Elusys Holdings, a company controlled by our Chairman, Chief Executive Officer, and President, Jeffrey Wolf for approximately $2.5 million before working capital, escrow adjustments and transaction expenses. Total consideration included $0.5 million of cash received at closing, $0.3 million related to consideration from a one-year convertible note, and fair value of $1.7 million in future payments from Elusys upon the achievement by Elusys of certain financial goals. The gain on the transaction was approximately $1.5 million.

The Company has separately reported the financial results of Elusys as discontinued operations in our consolidated statements of operations and comprehensive loss for the years ended December 31, 2023 and 2022, respectively. Assets and liabilities of discontinued operations in the consolidated balance sheet have a carrying value of $0 as of December 31, 2023.

Derecognition and Gain from Disposal of Discontinued Operations

As a result of the Elusys Therapeutics, Inc. sale and pursuant to the terms and conditions of the divestiture agreement entered into with Elusys Holdings, the Company ceased to have a financial interest in Elusys Therapeutics, Inc. as of December 27, 2023. Because the Company was selling all of its equity interest in Elusys Therapeutics, a wholly owned subsidiary that met the definition of a business, the Company considered deconsolidation guidance under ASC 810-10-40 Consolidation – Derecognition. The derecognition of Elusys Therapeutics requires the recognition of a gain or loss measured as the difference of fair value of consideration received (NCI is not applicable for Elusys) less the Company’s carrying value of Elusys Therapeutics. The Company concluded that the divestiture agreement was to be accounted for under derecognition guidance and required the company to record a gain on sale for the excess of consideration received over carrying value of assets derecognized and liabilities recognized.

Pursuant to the Agreement, Elusys Holdings was obligated to pay us $500,000 on December 11, 2023, which payment was timely completed. Elusys Holdings  is further obligated to pay to us on an annual basis a royalty fee equal to 3% of

F-10

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

gross revenue received by Elusys Holdings or any of its affiliates or their respective successors or licensees from all sales of the anthrax antitoxin known as ANTHIM® during the period commencing on January 1, 2024 and ending on June 30, 2031; provided that, if as of December 31, 2028, we have not received an aggregate of $5,000,000 in such royalty fees, Elusys Holdings  will be obligated to pay to us  no later than March 1, 2029 a cash payment equal to the difference between the aggregate amount of such royalty fees received by us  and $5,000,000.

Pursuant to the Agreement, at the December 27, 2023 closing of the Divestiture Transaction (the “Divestiture Closing”), Elusys Holdings assumed certain specified liabilities and manufacturing commitments relating to Elusys Therapeutics’ business, which at the time of the Divestiture were estimated at $51.4 million. The assumed liabilities and manufacturing commitments include all amounts owed to the former owners of Elusys Therapeutics under that certain Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) by and among us, Heat Acquisition Sub 1, Inc., Elusys Therapeutics and Fortis Advisors LLC, in its capacity as “Stockholders’ Representative,” which provides that we will remain liable if Elusys Holdings fails to satisfy its obligations to pay merger consideration under the Merger Agreement. In addition, from and after the Divestiture Closing, Elusys Holdings asumed all operating costs of Elusys Therapeutics, including the costs incurred after the closing related to Elusys Therapeutics employees, consultants, and regulatory and research costs. Mr. Wolf and William Ostrander, our Chief Financial Officer, will continue to serve in their current positions with us and also continue to serve as the Chief Executive Officer and Chief Financial Officer, respectively, of Elusys Holdings.

Also in connection with the transaction, we entered into a Shared Services Agreement with the Buyer setting forth the terms on which we will provide to Buyer, on a transitional basis, certain services or functions that it has historically provided to Elusys. Shared services will include various administrative, accounting, billing, cash management and banking and budgeting services and other support services. In consideration for such services, the Buyer will pay fees to us for the services provided, and those fees will generally be in amounts intended to allow us to recover all of its direct and indirect costs incurred in providing those services. We will charge the Buyer a fee for services performed by (i) our employees which shall be a percentage of each employee’s base salary based upon an allocation of their business time spent providing such services and (ii) third parties, the fees charged by such third parties. Buyer will also pay us for general and administrative expenses incurred by us attributable to both the operation of the Buyer and us (other than the provision of the services performed by us employees) and the provision of the shared services. As of December 31, 2023, no such services were provided.

The fair value of consideration received is shown in the following table:

	2023
Upfront cash consideration	$	500,000
Estimated fair value of 3% ANTHIM earnout	$	1,720,000

3.        Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Scorpius Holdings, Inc., and its subsidiaries (“the Company” or “Scorpius”), Pelican Therapeutics, Inc. (“Pelican”), Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax, Inc., Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.), Scorpius Biomanufacturing, Inc. (formerly Scorpion Biological Services, Inc), Blackhawk Bio, Inc., and Abacus Biotech, Inc. The functional currency of the entities located outside the United States of America (the foreign entities) is the applicable local currency of the foreign entities. Assets and liabilities of the foreign entities are translated at period-end exchange rates. Statement of operations accounts are translated at the average exchange rate during the period. The effects of foreign currency translation adjustments are included in other comprehensive loss, which is a component of accumulated other comprehensive loss in stockholders’ equity. All significant intercompany accounts and transactions have been eliminated in consolidation. The December 31, 2023 and 2022 year-end financials include an 85% controlling interest in Pelican and a 94% controlling interest in Scorpius Holdings, Inc. Scorpius Holdings, Inc. accounts for its less than 100% interest in the consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Accordingly, the Company presents non-controlling interest as a component of stockholders’ equity on its consolidated balance sheets and reports non-controlling interest net loss under the heading “net loss – non-controlling interest” in the consolidated statements of operations and comprehensive loss.

Going Concern Uncertainty

The Company has an accumulated deficit of $254.4 million as of December 31, 2023 and a net loss of approximately $46.8 million for the year ended December 31, 2023 and has not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable future. The Company expects significant expenses in connection with its ongoing activities, particularly as the Company ramps up operations in its in-house bioanalytic, process development and manufacturing facility in San Antonio, TX. In addition, any new business ventures that the Company may engage in are likely to require commitments of capital. Accordingly, the Company will need to obtain substantial additional funding in connection with its planned operations. Adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it will be forced to delay, reduce or eliminate its research and development programs, any future commercialization efforts or the manufacturing services it plans to provide. To meet its

F-12

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

capital needs, the Company intends to continue to consider multiple alternatives, including, but not limited to, additional equity financings such as sales of its common stock under at-the-market offerings, debt financings, equipment sale leasebacks, partnerships, grants, funding collaborations and other funding transactions, if any are available. As of December 31, 2023, the Company had approximately $2.4 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

Risk and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, a small customer base with mostly short-term contracts, uncertainty of market acceptance of the Company’s service offerings, market competition from similar and larger sized CDMO companies, competitive pricing pressure, and dependence on key individuals and sole source suppliers.

The Company depends on third-party suppliers for key materials and services used in research and development, as well as manufacturing processes, and is subject to certain risks related to the loss of these third-party suppliers or their inability to supply adequate materials and services. If third-party suppliers do not supply raw materials on a timely basis, the Company’s manufacturing services may be delayed or canceled which would adversely impact our financial condition and results of operations. If our suppliers are non-compliant with the FDA’s quality system regulations or other applicable laws or regulations, the Company would be required to find alternative suppliers.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, useful lives of fixed assets, consideration receivable, other intangible assets, income taxes, stock-based compensation, right-of-use assets and lease liabilities, estimates used in divestiture accounting, and useful lives of intangible assets. Actual results may differ from those estimates.

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing  performance. To date, the CODM has viewed the operations and managed the business as one segment.

Cash and Cash Equivalents

The Company considers all cash and other highly liquid investments with initial maturities from the date of purchase of three months or less to be cash and cash equivalents.

Short-term Investments

The Company’s short-term investments are equity securities and are carried at their fair value based on quoted market prices. Realized and unrealized gains and losses on equity securities are included in net earnings in the period earned or incurred.

F-13

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Derivative Financial Instruments

The Company has issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC 815 Derivatives and Hedging because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.”

The fair value of the warrants, including the warrants issued in connection with the January 2020 common stock offering and recorded as liability, was determined using the Monte Carlo simulation model, which is deemed to be an appropriate model due to the terms of the warrants issued. The fair value of warrants was affected by changes in inputs to the Monte Carlo simulation model including the Company’s stock price,expected stock price volatility, the remaining term, and the risk-free interest rate. This model uses Level 3 inputs, including stock pricevolatility, in the fair value hierarchy established by ASC 820 Fair Value Measurement. At December 31, 2023 the fair value of such warrants was $nil.

Concentration of Credit Risk

At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits. The Company has never experienced any losses related to these balances. As of December 31, 2023, there were no cash amounts in excess of $250,000. As of December 31, 2022, the uninsured balance was $7.8 million. The Company does not believe it is exposed to significant credit risk on cash and cash equivalents.

Property and Equipment

Property and equipment are stated at cost and are capitalized. Depreciation is calculated using the straight-line method and is based on estimated useful lives of five years for lab equipment, three years for computer equipment, eight years for furniture and fixtures and vehicles, and the lesser of the useful life or life of the lease for leasehold improvements.

Leases

The Company leases office space and certain equipment under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases. As such, the Company assesses all arrangements that convey the right to control the use of property, plant and equipment at inception to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset. When a modification to a lease occurs, the lease liability and right-of-use asset is remeasured based on the remaining lease payments and incremental borrowing rate as of the effective date of the modification.

Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the accompanying consolidated statements of operations and comprehensive loss.

The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

F-14

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

We do not record leases with terms of 12 months or less on the Consolidated Balance Sheets, and are expensed as incurred.

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during each year. Fully diluted net loss per share is computed using the weighted average number of common shares and dilutive securities outstanding during each year. Dilutive securities having an anti-dilutive effect on diluted loss per share are excluded from the calculation.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with ASC 740, Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employee directors using a fair value method that requires the recognition of compensation expense for costs related to all stock-based payments, including stock options and restricted stock units. The fair value method requires the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model. The fair value of restricted stock units is estimated based on the closing price of the Company’s stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for forfeitures as they occur. The Company settles exercises of stock options with newly issued shares of its common stock.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes-Merton option pricing model on the date of grant for stock options and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, and expected term. The expected volatility rates are estimated based on average historical stock price volatility of its own data. The expected term for the years ended December 31, 2023 and 2022 represents the average time that options are expected to be outstanding based on the average of the vesting term and the contractual term of the option. We account for forfeitures as they occur. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Net Loss Attributable to Non-controlling Interests

Net loss attributable to non-controlling interests is the result of the Company’s consolidation of subsidiaries of which it does not own 100%. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican, a related party prior to

F-15

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

acquisition, for 35,000 shares of the Company’s common stock. The stock exchange resulted in the Company owning 100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. Therefore, the Company’s net loss attributable to non-controlling interests relates to the 15% ownership of Pelican and 6% ownership of Scorpius Biomanufacturing that Scorpius does not own as of December 31, 2023 and 2022.

Deferred Revenue

Deferred revenue is comprised of biomanufacturing and process development customer deposits received in advance of our fulfillment of performance obligations.

License Agreements

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In-as-much as the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. As of December 31, 2023 and December 31, 2022, there was $0.03 million and $0.04 million of deferred revenue related to the Shattuck license agreement.

Process Development

Process development deferred revenue generally represents customer payments received in advance of the Company’s fulfillment of performance obligations associated with the custom development of a manufacturing process and analytical methods for a customer’s product. As of December 31, 2023 and December 31, 2022, there was $2.4 million and $1.6 million of deferred revenue related to process development, respectively.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price using the most likely method based on historical experience as well as applicable information currently available. Shipping and handling costs associated with inbound freight are capitalized to inventories and relieved through cost of sales as inventories are sold.

Shipping and handling costs associated with the delivery of products are included in selling, general and administrative expenses in our consolidated statements of income.

Payment terms and conditions vary by contract type, although terms generally require payment within 30 to 60 days of the invoice date. In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied; however, our contracts do not contain a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our

F-16

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

services, not to receive financing from our customers or to provide customers with financing. The Company has applied the practical expedient in ASC 606 and excludes information about a) remaining performance obligations that have an original expected duration of one year or less and b) transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. As of December 31, 2023, we do not have any unsatisfied performance obligations for contracts greater than one year.

Product Sales

The Company recognizes revenue from product sales when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. The Company invoices its customers after acceptance of the product and invoice payments are generally due within 30 days of the invoice date. The Company records product sales net of any variable consideration, including refund rights. The Company uses the most likely amount method when estimating its variable consideration, unless terms are specified within contracts. The Company recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period. These estimates may differ from actual consideration received. The Company evaluates these estimates to reflect known changes.

Grant Revenue

The Company recognizes revenue related to the Cancer Prevention and Research Institute of Texas (“CPRIT”) contract, which is being accounted for under Accounting Standards Update (“ASU”) No. 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made, as a conditional non-exchange contribution.

The CPRIT grant covered the period from June 1, 2017 through May 31, 2023, for a total grant award of up to $15.2 million. CPRIT advances grant funds upon request by the Company consistent with the agreed upon amounts and schedules as provided in the contract. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and the third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million was received in April 2023. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. When grant funds are received after costs have been incurred, the Company records revenue and a corresponding grants receivable until grant funds are received. As of December 31, 2023, all $15.2 million has been recognized and received.

License Revenue

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck Labs, Inc. (“Shattuck”) paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In March 2023, the Company received a milestone payment of $100,000 from Shattuck due to completion of a Phase 1A monotherapy dose escalation clinical trial of SL-172154. However, the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. See Note 18, “Subsequent Events.”

Process Development Revenue

Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an input method by tracking the progress toward completion based on the ratio of actual labor hours incurred to date to the Company’s estimated labor hours to complete. Under a process development contract, the customer owns the product details and process, which have no alternative use. Each process represents a distinct service that is sold

F-17

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, the Company is entitled to consideration for progress to date that includes an element of profit margin.

The transaction price for services provided under the Company’s contracts reflects its best estimate of the amount of consideration to which it is entitled in exchange for providing goods and services to our customers. For contracts with multiple performance obligations, the Company allocates transaction price to each performance obligation identified in a contract on a relative standalone selling price basis. If observable standalone selling prices are not available, the Company estimates the applicable standalone selling price based on the pricing of other comparable services or on a price that the Company believes the market is willing to pay for the applicable service.

In determining the transaction price, the Company considers the different sources of variable consideration including, but not limited to, discounts, credits, refunds, price concessions or other similar items. The Company includes in the transaction price some or all of an amount of variable consideration, utilizing the most likely method, only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The actual amount of consideration ultimately received may differ.

Geographic Concentration

The Company attributes revenue to the individual countries where the customer is headquartered. The Company derived approximately 100% of its revenues from the United States during the year ended December 31, 2023 and approximately 94% of its revenues from Canada and approximately 6% of its revenues from the United States during the year ended December 31, 2022.

Business Combinations

The accounting for the Company’s business combinations consists of allocating the purchase price to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. The Company has up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to goodwill. Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among other factors, analysis of historical performance and estimates of future performance. The Company has used discounted cash flow analyses, which were based on its best estimate of future revenue, earnings and cash flows as well as its discount rate, adjusted for risk, and estimated attrition rates.

Goodwill and Intangible Assets

The Company classifies intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company determines the useful lives of definite-lived intangible assets after considering specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, and other economic facts; including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their estimated useful lives. Intangible assets that are deemed to have indefinite lives, including goodwill, are reviewed for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test for indefinite-lived intangibles, other than goodwill, consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill on an annual basis or when events or changes in circumstances indicate a potential impairment exists, using a fair value-based test. The Company records a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value. Refer to Note 9, “Goodwill and other intangible assets” of the Notes to Consolidated Financial Statements for additional information on impairment.

In-process research and development (“IPR&D”) assets acquired in a business combination are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that the Company acquires, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval and the ability to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of the carrying value of the IPR&D assets over fair value. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Contingent Consideration

Consideration paid or received as a result of a purchase or sale of a business may include potential future payments that are contingent upon the acquired business achieving certain milestones in the future (“contingent consideration”). Contingent consideration is measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, the estimated timing of milestone achievement, and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. The milestone payments will be made upon the achievement of milestones as well as royalty payments. Subsequent to the date of acquisition, the Company reassesses the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. Any adjustment to the contingent consideration will be recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration assets and liabilities expected to be settled within 12 months after the balance sheet date are presented in current asset and current liabilities sections, with the non-current portion recorded with other long-term assets and under long term liabilities in the consolidated balance sheets. As of December 31, 2023, there is $0.3 million of contingent consideration receivable, related party representing the fair value of future proceeds from the off-market issuance on a convertible note in Current assets and $1.7 million  contingent earn-out receivable, related party representing royalty payments on future revenue provided as purchase consideration from the divestiture of Elusys Therapeutics in long-term assets, both reported on the Consolidated Balance Sheet as of December 31, 2023. During the year ended December 31, 2022, $3.3 million of contingent consideration related to Pelican was

written off as PTX-35 will not continue on to a Phase 2 trial. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Cost of revenues and selling, general and administrative expenses

Cost of revenues consists of production wages, material costs and overhead, and other costs related to the recognition of revenue. Selling, general and administrative expenses consist of salaries and related costs for administrators, public company costs, business development personnel as well as legal, patent-related expenses and consulting fees. Public company costs include compliance, auditing services, tax services, insurance and investor relations.

Research and Development

Research and development expenses relate to our investments in additions and improvements to our manufacturing process, process development, and costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of the Company’s product candidates and other expenses relating to the design, development, testing and enhancement of its product candidates.

Accounts Receivable

Accounts receivable are primarily comprised of amounts owed to us for services and sales provided under our customer contracts and are recorded at the invoiced amount net of an allowance for credit losses, if necessary. The Company applies judgment in assessing the ultimate realization of our receivables and we estimate an allowance for credit losses based on various factors, such as the aging of our receivables, historical experience, and the financial condition of our customers.

Prepaid Expenses and Other Current Assets

The Company’s prepaid expenses and other current assets consist primarily of amounts paid in advance for manufacturing activities, clinical trial support, contract assets and insurance. Contract assets consist of unbilled receivables.

Discontinued Operations

In accordance with ASC Subtopic 205-20, Presentation of Financial Statements: Discontinued Operations, a disposal of a component of an entity or a group of components of an entity (“disposal group”) is required to be reported as discontinued operations if the disposal group represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the disposal group meets discontinued operations criteria. Assets and liabilities of disposal group meeting discontinued operations treatment is presented separately as held-for-sale. At the same time, the results of all discontinued operations, less applicable income taxes, are reported as components of net loss separate from the net loss of continuing operations.

Impact of Recently Issued Accounting Standards:

In December 2023, the FASB issued ASU 2023-09, which requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are evaluating the disclosure requirements related to the new standard.

In November 2023, the FASB issued ASU 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses, including for single reportable

F-20

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

segment entities. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. We are evaluating the disclosure requirements related to the new standard.

4.        Short-Term Investments

Short-term investments consist of equity securities. The Company reports its securities at fair value as of December 31, 2023 and 2022, respectively. Unrealized gains (losses) on securities of $0.1 million and ($1.7) million, respectively, are reported in the consolidated statements of operations and comprehensive loss for the years ended December 31, 2023 and 2022. Short-term investments at December 31, 2023 and 2022 consisted of mutual funds with fair values of $2.2 million and $35.8 million, respectively.

5.        Fair Value of Financial Instruments

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level I – Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level II – Observable inputs, other than Level I prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The Company’s cash equivalents are classified within Level I of the fair value hierarchy.

As of December 31, 2023 and 2022, the fair values of cash and cash equivalents, accounts payable, and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. The Company’s short-term investments consist of Level I securities which are comprised of highly liquid mutual funds. The estimated fair value of the short-term investments was based on quoted market prices. There were no transfers between fair value hierarchy levels during the years ended December 31, 2023 or 2022.

The fair value of financial instruments measured on a recurring basis is as follows:

	As of December 31, 2023

The change in the fair value of the contingent consideration of ($0.1) million and ($0.1) million for the years ending December 31, 2023 and 2022, respectively, was primarily due to the change in timing and amount of the contract deferred consideration. The reclassification of ($4.6) million of contingent consideration for the year ending December 31, 2023 is due to the divestiture of Elusys Therapeutics, Inc. Therefore, the Company has separately reported the financial results of Elusys as discontinued operations in our consolidated statements of operations and comprehensive loss for the years ended December 31, 2023 and 2022, respectively, and presented the related assets and liabilities as of discontinued operations in the consolidated balance sheet as of December 31, 2022.

The change in fair value of contingent earn-out receivable, related party of $1.7 million for the year ended December 31, 2023 represents the fair value of contingent future royalty payments from Elusys Holdings, Inc. on potential future sales generated by Elusys Therapeutics, Inc., as part of the divestiture agreement.

The change in the fair value of the contingent consideration of ($3.3) million for the year ended December 31, 2022 was primarily due to the effect of the change in discount rate, probability of achieving milestones, passage of time on the fair

value measurement and discontinuation of the PTX-35 trial, thus leading to the write-off of the Pelican contingent consideration. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statement of operations and comprehensive loss.

The following table presents quantitative information about the inputs and valuation methodologies used for the Company’s fair value measurements of contingent consideration classified as Level 3 (which have now been reclassified to current liabilities of discontinued operations in our consolidated balance sheets) as of December 31, 2023 and December 31, 2022:

The Company records certain non-financial assets on a non-recurring basis, including goodwill and in-process R&D. This analysis requires significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital.

6.        Acquisitions

Pelican Therapeutics

In 2017, the Company consummated the acquisition of 80% of the outstanding equity of Pelican, a related party, and Pelican became a majority owned subsidiary of the Company. During the quarter ended March 31, 2018, cash

SCORPIUS HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

consideration of approximately $300,000 was distributed to the participating Pelican stockholders and the remainder of approximately $200,000 for certain Pelican liabilities not satisfied was recognized as other income in the statements of operations and comprehensive loss for the period. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican. The stock exchange resulted in Heat increasing its controlling ownership in Pelican from 80% to 85%.

Under the agreement, the Company was also obligated to make future payments based on the achievement of certain clinical and commercialization milestones, as well as low single digit royalty payments and payments upon receipt of sublicensing income. However, due to the discontinuation of PTX-35 no future milestone payments are expected to be made. The goodwill and in-process R&D resulting from the acquisition were fully impaired as of December 31, 2022 (see Note 8).

Elusys Therapeutics

On April 18, 2022 (“Closing Date”), the Company closed on the acquisition of Elusys Therapeutics. Scorpius paid at the closing a cash upfront payment of $3,000,000 to the former owners (“Sellers”) of Elusys Therapeutics. Scorpius is obligated to pay the Sellers $2,000,000 of deferred cash consideration (“Merger Consideration”) at the same time that the payment of the receivable consideration is to be distributed to the Sellers as described below, which was paid in the second quarter of 2022. Earn out payments will be paid to the sellers for a period of 12 years from the date of the closing equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the closing date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded, or entered into during the first nine years after the Closing Date.

Per the merger agreement that was executed in connection with the acquisition of Elusys Therapeutics (the “Merger Agreement”), upon collection of the Elusys Therapeutics contract receivables of $24.5 million, The Company is obligated to remit payment of $22.3 million (the “Receivable Consideration”) to the Sellers. In April 2022, $20.8 million was remitted to the Sellers less a hold back of $1.5 million related to future fulfillment cost. Elusys Therapeutics  is expected to receive additional revenue from the future fulfillment of an existing U.S. Government contract, and the Company agreed to fulfill the future obligations of Elusys Therapeutics under such contract and pass through and distribute to the Sellers the payments received under such contract minus the costs associated with such fulfillment obligations, subject to certain adjustments to the Merger Consideration specified in the Merger Agreement, including income taxes payable with respect to such payments (the “Contract Deferred Consideration”). The Merger Agreement further provides that 80% of any amounts paid to and received by Elusys Therapeutics (the “Additional Earn Out”) after the Closing Date and prior to June 30, 2023, shall be paid to the Sellers, subject to certain adjustments specified in the Merger Agreement.

The Company acquired Elusys Therapeutics to expand its role in the biodefense space, complementing its focus to target emerging biological threats. The Company initially expected to leverage the capabilities of its potential Scorpius Biomanufacturing facility in Manhattan, Kansas, to manufacture Elusys Therapeutics’ therapies internally and therefore benefit from significant operating synergies, cost savings, as well as enhanced oversight, quality control, and speed to market.  However, the Company is unable to manufacture the Elusys Therapeutics’ therapies internally.  In addition, the Company has to date been unable to generate sufficient revenue from its current manufacturing facility or raise sufficient capital to enable it to build the biomanufacturing facility in Manhattan, Kansas and instead has been required to place contract with third parties for the manufacture of the Elusys Therapeutics’ therapies. See Note 11-Commitments and Contingencies.

The fair value of the purchase consideration was approximately $42.9 million. The purchase consideration consists of $3.0 million in cash and $2.0 million in deferred cash consideration, and the estimated fair value of the contingent and deferred consideration liabilities related to the receivable consideration, contract deferred consideration, earn out and additional earn out totaling $37.9 million. The valuation of the contract deferred consideration and earn out liabilities were valued using a discounted cash flow analysis that utilized discount rates of 24% and 14%, respectively. The value of the additional earn out liability was calculated as 80% of the estimated gross sales price of 1,500 pre-filled vials of ANTHIM®, less

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

estimated fulfillment costs to be incurred. The value of the receivable consideration was equal to the value of the contract receivables acquired, less holdback expenses, as this liability was settled within 30 days of the Closing Date.

The acquisition of Elusys Therapeutics was accounted for as a business combination and reflects the application of acquisition accounting in accordance with ASC 805, Business Combinations. The acquired Elusys Therapeutics’ assets, including identifiable intangible assets and liabilities assumed, have been recorded at their fair values with the excess purchase price assigned to goodwill. The recognition of goodwill is largely attributed to the value paid for Elusys Therapeutics’ capabilities, which will broaden the Company’s role in the biodefense space. The goodwill recorded for this transaction was valued at $3.9 million and will be deductible for tax purposes over 15 years.

The purchase price of $42.9 million has been allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was recorded as goodwill.

The following table highlights the components of the purchase consideration:

Aggregate consideration:
Cash consideration	$	3,000,000
Deferred cash consideration		2,000,000
Earn out		5,900,000

Receivable consideration		22,318,685
Contract deferred consideration		4,900,000
Total purchase consideration	$	42,853,685

The purchase price allocation resulted in the following amounts being allocated to the assets acquired and liabilities assumed as of the closing date based on their respective fair values summarized below:

Pelican Goodwill and In-Process R&D

Goodwill of $2.2 million and in-process R&D of $5.9 million were recorded in connection with the acquisition of Pelican, as described in Note 6 and have been allocated to the Pelican reporting unit. During the fourth quarter of 2021, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim impairment analysis using the income approach and in-process R&D with a total carrying value of $5.9 million was written down to its estimated fair value of $3.5 million and an impairment charge of $2.4 million during the fourth quarter of 2021 was recorded and goodwill in the amount of $1.5 million was fully impaired. During the third quarter of 2022, the Company elected to terminate any further development of PTX-35. As a result of the termination, the in-process R&D affiliated with PTX-35, in the amount of $3.5 million, has been fully impaired.

Elusys Therapeutics Goodwill and Intangible Assets

Goodwill of $3.3 million and an intangible asset of $9.7 million was recorded in connection with the acquisition of Elusys which has been allocated to the Elusys Therapeutics reporting unit. During the fourth quarter of 2022, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim goodwill impairment analysis using the income approach. However, through its quantitative analysis, the Company determined the carrying value was not in excess of its estimated fair value and therefore no impairment charge was recorded at December 31, 2022. Elusys Therapeutics’ intangible asset relates to the ANTHIM® formulation and is amortized over its remaining patent life, approximately 80 months. The Company’s annual impairment analysis was performed on April 1, 2023 using the income approach that determined the carrying value remained not in excess of its estimated fair value and, therefore, no impairment charge was necessary. During the second quarter of 2023, the Company finalized the purchase price allocation for the Elusys acquisition and recorded a measurement period adjustment that increased goodwill by approximately $0.6 million to a balance of $3.9 million.

As of September 30, 2023, the Company’s activities with regard to the divesture of the Elusys Therapeutics business met the criteria to report within discontinued operations. The Company has reclassified its previously issued financial statements to segregate the discontinued operations as of the earliest period presented. The Company evaluated its intangible asset and goodwill for impairment under ASC 360, Property, Plant, and Equipmment and ASC 350, Intangibles—Goodwill and Other. As a result, goodwill was fully impaired by $3.9 million and intangible assets were partially impaired by $2.3 million. These impairments resulted in the carrying value of the assets of discontinued operations being less than the fair value and therefore no loss has been recognized upon reclassification of the disposal group to discontinued operations treatment. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

The following table provides the Company’s goodwill, IPRD, and intangible assets as of December 31, 2023 and 2022:

In connection with the Merger Agreement for the acquisition of Elusys Therapeutics in April 2022, the Company agreed to pay earn out payments for a period of 12 years from the Closing Date equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the Closing Date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded or entered into during the first nine years after the Closing Date. The Merger Agreement also provides that the Company will remain liable for royalty payments if any buyer of Elusys Therapeutics fails to satisfy this obligation. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.Elusys relies on Lonza, a third-party manufacturer, to produce commercial quantities of its ANTHIM® bulk drug product requirements. Elusys has firm orders with Lonza for future purchases of bulk drug substance, with remaining total non-cancellable future commitments of approximately $51.4 million through 2025. If Elusys were to terminate certain firm orders with Lonza without cause, it will be required to pay for bulk drug substance scheduled for manufacture under its arrangement. This assumed manufacturing commitment was transferred to Elusys Holdings as part of the Divestiture Transation. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023, with Elusys Holdings, Inc. (“Elusys Holdings”), Elusys Holdings purchased from the Company a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys’ Holdings election and obtaining stockholder approval of the issuance of shares of the Company’s common stock upon such conversion. The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of the Company’s common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of the Company’s common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of the Company’s common stock upon conversion of the Note. The cash proceeds for the Note were received on January 26, 2024.

Grant Revenue

In June 2016, Pelican entered into a cancer research grant contract (“Grant Contract”) with CPRIT, under which CPRIT awarded a grant not to exceed $15.2 million for use in developing cancer treatments by targeting a novel T-cell costimulatory receptor (namely, DR3/TNFRSF25). The Grant Contract initially covered a period from June 1, 2016 through November 30, 2019, as amended, was extended to May 30, 2022. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and a third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million was received in April 2023. As of December 31, 2023, all $15.2 million has been recognized and received.

The grant was subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to provide $7.6 million in matching funds over the life of the project. Upon commercialization of the product, the terms of the grant require Pelican to pay tiered royalties in the low to mid-single digit percentages. Such royalties reduce to less than one percent after a mid-single-digit multiple of the grant funds have been paid to CPRIT in royalties.

License revenue

In June 2016, Scorpius licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases with Shattuck. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In March 2023, the Company received a milestone payment of $100,000 from Shattuck due to completion of a Phase 1A monotherapy dose escalation clinical trial of SL-172154. Refer to Note 19, “Subsequent Events,” for additional information about the subsequent sale of the Shattuck license.

Process Development Revenue

During the years ended December 31, 2023 and 2022, the Company recognized $6.6 million and $0.1 million of process development revenue, respectively. Revenue was primarily derived from two customers who represented 86% of total recognized process development revenue for the year ended December 31, 2023. One customer accounted for 74% of process development revenue for the fiscal year ended December 31, 2023, and is migrating to a larger CDMO for commcrcial manufacture of their product.

Accounting for Stock-Based Compensation:

Stock Options - Under the Plans, we have issued stock options. A stock option granted gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined exercise price for a specific period of time. The exercise price is determined by the closing stock price on the date of the grant. We typically issue options that vest over four years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plans, the contractual life of the option grants may not exceed ten years. During the years ended December 31, 2023, and 2022, we issued options that expire ten years from the date of grant. No stock options were granted during the year December 31, 2023.

Fair Value Determination - We have used the Black-Scholes-Merton option pricing model to determine fair value of our stock option awards on the date of grant.

The following weighted-average assumptions were used for option grants during the years ended December 31, 2023:

● Volatility – The Company used an average historical stock price volatility of its own data.

● Expected life of options – The expected term represents the period that the Company’s stock option grants are expected to be outstanding. The Company elected to utilize the “simplified” method to estimate the expected term as the company does not have sufficient appropriate exercise data on which to base its estimate. Under this approach, the weighted-average expected life is presumed to be the average of the vesting term and the contractual term of the option.

● Risk-free interest rate – The rate is based on U.S. Treasury interest rates at the time of the grant whose term is consistent with the expected life of the stock options.

● Dividend yield – The expected dividend yield was considered to be 0% in the option pricing formula since the Company had not paid any dividends and had no plan to do so in the future.

● Forfeitures – The Company’s policy is to account for forfeitures as they occur.

The following table summarizes assumptions used in our calculations of fair value for the year ended December 31, 2022. No stock options were granted during the year ended December 31, 2023.

	2022
Dividend yield	—	%
Expected volatility	100.85-105.09	%
Risk-free interest rate	1.95-3.61	%
Expected lives (years)	5.3-6.1	years

Stock Option Activity – No stock options were granted during the year ended December 31, 2023. The weighted-average grant date fair value of options granted during the year ended December 31, 2022 was $0.87.

Unrecognized compensation expense related to unvested stock options was $2.0 million as of December 31, 2023, which is expected to be recognized over a weighted-average period of 1.00 years and will be adjusted for forfeitures as they occur.

Restricted Stock - Under the Plans, the Company has issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors and Executives vest 50% on the grant date, 30% on the first anniversary and 10% each anniversary thereafter. The grant date fair value of the restricted stock is equal to the closing market price of the Company’s common stock on the date of grant.

Restricted Stock Activity - The following table summarizes the restricted stock activity during the years ended December 31, 2023 and 2022:

The aggregate fair value of awards that vested during the years ended December 31, 2023 and 2022 was $0.1 million and $1.6 million, respectively.

RSUs - Under the Plans, the Company has time-based RSUs. RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has no voting rights until the RSUs vest. The employees' time-based RSUs will result in the delivery of shares in pro-rata increments commencing on the award date. The grant date fair value of the RSUs is equal to the closing market price of the Company’s common stock on the grant date. The Company recognizes the grant date fair value of RSUs of shares it expects to issue as compensation expense ratably over the requisite service period.

The tax effects of temporary differences and operating loss carryforwards that gave rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows at December 31, 2023 and 2022:

At December 31, 2023 and December 31, 2022, the Company evaluated all significant available positive and negative evidence, including the existence of losses in recent years and management’s forecast of future taxable income, and, as a result, determined it was more likely than not that federal, foreign, and state deferred tax assets, including benefits related to net operating loss carryforwards, would not be realized. Accordingly, the deferred tax assets have been fully offset by a valuation allowance of $40.5 milion and $32.6 million as of December 31, 2023 and 2022, respectively.

As of December 31, 2023, and 2022, the Company’s U.S. federal net operating loss (“NOL”) carryforwards were approximately $197.0 million and $174.3 million, respectively. However, due to Section 382 limitations, only $136.3 million of the NOLs are available to offset future taxable income. Of the $136.3 million of available federal net operating loss carryforwards, $128.2 million were incurred after December 31, 2017 and therefore, will not expire. The remaining $8.1 million of available federal net operating loss carryforwards begin to expire in 2029. As of December 31, 2023, and 2022, the Company had state NOL carryforwards of approximately $126.5 million and $124.5 million, respectively. Due to Section 382 limitations, only $2.8 million of the state NOLs are available to offset future taxable income. The state net operating losses that are available to offset future taxable income begin to expire in 2032.

The Company’s ability to utilize its NOL and research and development (R&D) credit carryforwards may be substantially limited due to ownership changes that have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain stockholders or public groups. The Company completed a Section 382 study during 2021. It was determined that the Company has experienced five ownership changes of over 50% since 2013, the latest occurring on June 30, 2020. Going forward, the utilization of loss carryforwards and tax credits generated before June 30, 2020 will be subject to an annual limitation. As a result of the ownership changes and limitations, $58.2 million of federal NOLs

and $2.9 million of federal R&D credits will expire unutilized, in addition to Section 382 limits on Pelican already in place.

The Company has evaluated its tax positions to consider whether it has any unrecognized tax benefits. As of December 31, 2023, the Company had no unrecognized tax benefits. The Company does not anticipate a significant change in total unrecognized tax benefits or the Company’s effective tax rate due to the settlement of audits or the expiration of statutes of limitations within the next twelve months. Furthermore, the Company does not expect any cash settlement with the taxing authorities as a result of these unrecognized tax benefits as the Company has sufficient unutilized carryforward attributes to offset the tax impact of these adjustments.

The following is a tabular reconciliation of the Company’s change in gross unrecognized tax positions at December 31, 2023:

	2023		2022
Beginning balance	$	—	$	—
Gross increases for tax positions related to the acquisition of Elusys Therapeutics		1,480,974		—
Gross increases for tax positions related to the current periods		-		—
Divestiture of equity interests in ElusysTherapeutics		(1,480,974)		—
Ending balance	$	—	$	—

The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions as of December 31, 2023 and 2022 that would impact the effective tax rate if recognized, and as such, no interest or penalties were recorded to income tax expense.

The Company has analyzed its filing positions in all significant federal, state, and foreign jurisdictions where it is required to file income tax returns, as well as open tax years in these jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, and local tax examinations by tax authorities for years before 2020, although carryforward attributes that were generated prior to 2020 may still be adjusted upon examination by the taxing authorities if they either have been or will be used in a future period. No income tax returns are currently under examination by taxing authorities.

15. Leases

The Company accounts for its leases under ASC 842, “Leases”. The Company has determined that its leases for office and laboratory space without optional terms or variable components are operating leases.

The Company conducts its operations from leased facilities in Morrisville, North Carolina; San Antonio, Texas; and North Brunswick, New Jersey. The North Carolina lease will expire in 2030, the Texas lease will expire last in 2038, the New Brunswick leases will expire in July 2024. The leases are for general office space, manufacturing space, and lab space and require the Company to pay property taxes, insurance, common area expenses and maintenance costs.

In June 2021, the Company entered into a lease agreement with Durham KTP Tech 7, LLC, to lease a 15,996 square foot facility in Morrisville, North Carolina to expand its research and development activities. The lease has a term of eight years following the commencement date and provides the Company the option to extend the lease term for one five year term, however option to extend was not included in the ROU asset and liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. Scorpius,, upon commencement, recorded an operating lease right-of-use asset of $5.6 million and lease liability of $3.2 million for this lease in the accompanying consolidated balance sheets.

In October 2021, Scorpius entered into a lease agreement with Merchants Ice II, LLC to lease a 20,144 square foot facility in San Antonio, TX for general office, laboratory, research, analytical, and/or biomanufacturing purposes. Merchants Ice II, LLC is a nonprofit entity investing in the building with the intention to encourage development of emerging technologies. As a result, investments made by both Merchants Ice II, LLC and Scorpius into the building may qualify and share tax credits under the New Market Tax Credit (“NMTC”) program. Scorpius agreed that all investments and expenditures qualifying under the NMTC (i.e., certain equipment and building improvements) would be purchased by Merchants Ice II, LLC to generate the largest possible tax incentive and Scorpius would reimburse Merchants Ice II, LLC

for these payments. The lease officially commenced on September 15, 2022. As of December 31, 2022, Scorpius has reimbursed Merchants Ice II, LLC $24.3 million. Based on ASC 842, Scorpius has capitalized $13.2 million of the reimbursements as lab equipment, expensed $0.9 million as supplies and facilities, and $10.2 million has been included in the finance lease right-of-use asset. In 2023, additional NMTC tax credit payments totalling $3.1 million were received which resulted in a lease modification. The ROU asset and liability were adjusted to reflect the impacts of the modification. The lease has a term of fifteen years following the commencement date and provides Scorpius the option to extend the lease term for one fifteen-year term, and one subsequent ten year term upon expiration of the first extended term. These options to extend were not included in the ROU asset and lease liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. Scorpius upon commencement, recorded a finance lease right-of-use asset of $15.1 million and lease liability of $5.1 million for this lease in the accompanying consolidated balance sheets.

In December 2022, Scorpius entered into a lease agreement with TPB Merchants Ice LLC to lease a 8,042 square foot facility in San Antonio, TX for general office, laboratory, and/or biomanufacturing purposes. The lease has a term of fifteen years following the commencement date and provides the Company the option to extend the lease term for one ten year term, however option to extend was not included in the ROU asset and liability. It is subject to fixed rate escalation increases and provided up to $0.5 million for tenant improvements. The lease commenced in May 2023 and Scorpius recorded a finance lease right-of-use asset of $7.8 million and lease liability of $2.3 million for this lease in the accompanying consolidated balance sheets.

In December 2023, Scorpius entered into a lease agreement with EastGroup Properties, L.P. to lease a 22,262 square foot facility in San Antonio, TX for general office and warehouse purposes. The lease has a term of five years following the commencement date. It is subject to fixed rate escalation increases and provided up to $0.1 million for tenant improvements. Scorpius recorded a operating lease right-of-use asset of $0.9 million and lease liability of $1.0 million for this lease in the accompanying consolidated balance sheets.

Total cash paid for operating leases during the years ended December 31, 2023 and 2022 was $0.8 million and $0.8 million and is included within cash flows from operating activities within the consolidated statements of cash flows.

The Company leases furniture and specialized lab equipment under finance leases. The related ROU assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the asset. For the year ended December 31, 2023, additional finance equipment leases commenced and right-of-use assets of $2.2 million were recorded, and modifications to finance equipment leases were obtained totalling $0.07 million. Both are included within the supplemental disclosure for cash flow within the consolidated statements of cash flows.

The Company’s lease cost reflected in selling, general, and administrative of the statements of operations and comprehensive loss is as follows:

16.        Related Party Transactions

Prior to the acquisition of Elusys Therapeutics, Jeffrey Wolf, President, Chief Executive Officer and Chairman of the Board of Directors, was a director of Elusys Therapeutics and directly and through affiliated entities owned approximately 1.2% of the outstanding stock of Elusys Therapeutics, in the form of common stock, which is subordinate in terms of distributions to the Elusys Therapeutics preferred stock.

On December 27, 2023, pursuant to that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023 (the “Agreement”), that we entered into with  Elusys Holdings Inc., a Delaware corporation (“Buyer”), a company controlled by our Chairman, Chief Executive Officer and President, Jeffrey Wolf. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.”

17.        Net Loss Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Fully diluted net loss per common share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the periods. Common equivalent shares consist of stock options, restricted stock units, and warrants that are computed using the treasury stock method.

For the years ended December 31, 2023 and 2022, all of the Company’s common stock options, unvested restricted stock units and warrants are anti-dilutive and therefore have been excluded from the diluted net loss per common share calculation.

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023, with Elusys Holdings, Inc. (“Elusys Holdings”),  Elusys Holdings purchased from us a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”). The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of our common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note. The cash proceeds for the Note were received on January 26, 2024.

On January 29, 2024, we entered into a Patent Rights Sale and Assignment Agreement with Kopfkino IP, LLC (“Patent Agreement”). Pursuant to the Patent Agreement, in exchange for $1,000,000, we assigned our right, title and interest in and under the exclusive license agreement it entered into with Shattuck Labs, Inc. (“Shattuck”) in 2016, including our rights to certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us. The $1,000,000 payment was recorded as revenue and the remaining deferred revenue balance of $32,500 was also recorded as revenue in the first quarter of 2024. With the total assignment of all rights, no future income will be received in the future.

On March 9, 2024, we closed the offering contemplated by the Underwriting Agreement that we entered into on March 7, 2024 (the “Agreement”) with ThinkEquity, LLC, as representative of the several underwriters named therein (the “Underwriters”), pursuant to which we issued and sold  10,000,000 shares of our Common Stock at a price of $0.15 per share for net proceeds of approximately $1,300,000.

DESCRIPTION OF SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE

SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

Scorpius Holdings, Inc. (the “Company,” “we,” “us,” and “our”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is our common stock, par value $0.0002 per share (the “common stock”).

General

The following is a description of the material terms of our common stock.  This is a summary only and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Third Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), and our Second Amended and Restated Bylaws (the “Bylaws”), each of which are incorporated by reference as an exhibit to our Annual Report on Form 10-K.  We encourage you to read our Certificate of Incorporation, our Bylaws and the applicable provisions of the Delaware General Corporation Law, for additional information.

Description of Common Stock

Authorized Shares of Common Stock.  We currently have authorized 250,000,000 shares of common stock.

Voting.  The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors, and do not have cumulative voting rights. At all meetings of stockholders for the election of Directors a plurality of the votes cast shall be sufficient to elect, unless otherwise provided in the Certificate of Incorporation.

Dividends.  Subject to preferences that may be applicable to any then outstanding preferred stock, the holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Liquidation.  In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences.  The holders of our common stock have no preemptive, conversion or subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.

Fully Paid and Nonassessable.  All of our issued and outstanding shares of common stock are fully paid and nonassessable.

Stockholder Rights Plan

On March 11, 2018, our board of directors declared a dividend of one common share purchase right (a “Right”) for each outstanding share of our common stock, which was amended by Amendment No. 1 thereto on March 8, 2019, by Amendment No. 2 thereto on March 10, 2020, by Amendment No. 3 thereto on March 8, 2021, by Amendment No. 4 on March 11, 2022, by Amendment No. 5 thereto on March 11, 2023, by Amendment No. 6 thereto on December 11, 2023 and by Amendment No. 7 on March 11, 2024 to extend the expiration date of the stockholder’s rights plan to March 11, 2025.  The dividend was initially paid on March 23, 2018 (the “Record Date”) to the stockholders of record at the close of business on that date.  Each Right initially entitles the registered holder to purchase from us one share of common stock at a price of $14.00 per share of common stock (the “Purchase Price”), subject to adjustment.  The description and terms of the Rights are set forth in a Rights Agreement, dated as of March 11, 2018, as amended by Amendment No. 1 thereto dated March 8, 2019, Amendment No. 2 thereto dated March 10, 2020, Amendment No. 3 thereto dated March 8, 2021, Amendment No. 4 thereto dated March 11, 2022, Amendment No. 5

thereto dated March 11, 2023, Amendment No. 6 thereto dated December 11, 2023 and Amendment No. 7 thereto dated March 11, 2024 as the same may be further amended from time to time (the “Rights Agreement”), between the Company and Continental Stock Transfer & Trust Company, as Rights Agent (the “Rights Agent”).

The Rights are designed to assure that all of our stockholders receive fair and equal treatment in the event of a hostile takeover of the Company, to guard against two-tier or partial tender offers, open market accumulations and other tactics designed to gain control of the Company without paying all stockholders a fair price, and to enhance the board of director’s ability to negotiate with any prospective acquiror. Until the earlier to occur of (i) 10 business days following a public announcement that a person or group of affiliated or associated persons has become an Acquiring Person (as defined below) or (ii) 10 business days (or such later date as may be determined by action of the board of directors prior to such time as any person or group of affiliated or associated persons becomes an Acquiring Person) following the commencement of, or public announcement of an intention to make, a tender or exchange offer the consummation of which would result in any person or group of affiliated or associated persons becoming an Acquiring Person (the earlier of such dates being called the “Distribution Date”), the Rights will be evidenced, with respect to certificates representing common stock (or book entry shares of common stock) outstanding as of the Record Date, by such certificates (or such book entry shares) together with a copy of a summary of the Rights (the “Summary of Rights”).  Except in certain situations, a person or group of affiliated or associated persons becomes an “Acquiring Person” upon acquiring beneficial ownership of 20% or more of the outstanding shares of common stock.  Certain synthetic interests in securities created by derivative positions – whether or not such interests are considered to be ownership of the underlying common stock or are reportable for purposes of Regulation 13D of the Exchange Act – are treated as beneficial ownership of the number of shares of the common stock equivalent to the economic exposure created by the derivative security, to the extent actual shares of common stock are directly or indirectly beneficially owned by a counterparty to such derivative security. Amendment No. 6 exempted Mr. Wolf and his affiliated entity from being a Acquiring Person under certain specified circumstances.

The Rights Agreement provides that, until the Distribution Date (or earlier expiration of the Rights), the Rights will be transferred with and only with the common stock.  Until the Distribution Date (or earlier expiration of the Rights), new common stock certificates issued after the Record Date upon transfer or new issuances of common stock will contain a notation incorporating the Rights Agreement by reference.  Until the Distribution Date (or earlier expiration of the Rights), the surrender for transfer of any certificates for shares of common stock (or book entry shares of common stock) outstanding as of the Record Date, even without such notation or a copy of the Summary of Rights, will also constitute the transfer of the Rights associated with the shares of common stock represented thereby. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) 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.

The Rights are not exercisable until the Distribution Date. The Rights will expire at the close of business on March 11, 2025, unless the Rights are earlier redeemed or exchanged by the Company as described below.

The Purchase Price payable, and the number of shares of common stock (or cash, other assets, debt securities of the Company, or any combination thereof equivalent in value thereto) issuable, upon exercise of the Rights is subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the common stock, (ii) upon the grant to holders of the common stock of certain rights or warrants to subscribe for or purchase common stock at a price, or securities convertible into common stock with a conversion price, less than the then-current market price of the common stock or (iii) upon the distribution to holders of the common stock of evidences of indebtedness or assets (excluding regular periodic cash dividends or dividends payable in common stock) or of subscription rights or warrants (other than those referred to above).

The number of outstanding Rights is subject to adjustment in the event of a stock dividend on the common stock payable in shares of common stock or subdivisions, consolidations or combinations of the common stock occurring, in any such case, prior to the Distribution Date.

In the event that any person or group of affiliated or associated persons becomes an Acquiring Person, each holder of a Right, other than Rights beneficially owned by the Acquiring Person (which will thereupon become void), will thereafter have the right to receive upon exercise of a Right that number of shares of common stock (or cash, property debt securities of the Company, or any combination thereof) having a market value of two times the exercise price of the Right.

In the event that, after a person or group has become an Acquiring Person, the Company is acquired in a merger or other business combination transaction or 50% or more of its consolidated assets or earning power are sold, proper provisions will be made so that each holder of a Right (other than Rights beneficially owned by an Acquiring Person which will have become void) will thereafter have the right to receive upon the exercise of a Right that number of shares of common stock of the person with whom the Company has engaged in the foregoing transaction (or its parent) that at the time of such transaction have a market value of two times the exercise price of the Right.

At any time after any person or group becomes an Acquiring Person and prior to the earlier of one of the events described in the previous paragraph or the acquisition by such Acquiring Person of 50% or more of the outstanding shares of common stock, the board of directors may exchange the Rights (other than Rights owned by such Acquiring Person which will have become void), in whole or in part, for shares of common stock (or cash, other assets, debt securities of the Company, or any combination thereof with an aggregate value equal to such shares) at an exchange ratio of one share of common stock (or cash, other assets, debt securities of the Company, or any combination thereof equivalent in value thereto) per Right.

With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price. No fractional shares of common stock will be issued, and in lieu thereof a cash payment will be made based on then current market price of the common stock.

At any time prior to the time an Acquiring Person becomes such, the Board may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (the “Redemption Price”) payable, at the option of the Company, in cash, shares of common stock or such other form of consideration as the board of directors shall determine. The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the 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 right of the holders of Rights will be to receive the Redemption Price.

For so long as the Rights are then redeemable, the Company may, except with respect to the Redemption Price, amend the Rights Agreement in any manner.  After the Rights are no longer redeemable, the Company may, except with respect to the Redemption Price, amend the Rights Agreement in any manner that does not adversely affect the interests of holders of the Rights.

Until a Right is exercised or exchanged, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. For more detailed information, please see the Rights Agreement.

Potential Anti-Takeover Effects

Certain provisions set forth in our Certificate of Incorporation and Bylaws, our Rights Agreement and in Delaware law, which are summarized below, may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, including attempts that might result in a premium being paid over the market price for the shares held by stockholders.

Proposals of business and nominations. Our Bylaws generally regulate proposals of business and nominations for election of directors by stockholders. In general, Section 2.14 requires stockholders intending to submit proposals or nominations at a stockholders meeting to provide the Company with advance notice thereof, including information regarding the stockholder proposing the business or nomination as well as information regarding the proposed business or nominee. Section 2.14 provides a time period during which business or nominations must be provided to the Company that will create a predictable window for the submission of such notices, eliminating the risk that the Company finds a meeting will be contested after printing its proxy materials for an uncontested election and providing the Company with a reasonable opportunity to respond to nominations and proposals by stockholders.

Board Vacancies. Our Bylaws generally provide that only the board of directors (and not the stockholders) may fill vacancies and newly created directorships.

Special Meeting of Stockholders.  Our Bylaws generally provide that only the chairperson of the board of directors, the Chief Executive Officer, the President, the Secretary or any two directors may call a special meeting of

stockholders and that the board of directors may postpone, reschedule or cancel any special meeting of stockholders that was previously scheduled by the board of directors.

Stockholder Rights Plan.  The rights issued pursuant to the Rights Agreement, if not redeemed or suspended, could work to dilute the stock ownership of a potential hostile acquirer, likely preventing acquisitions that have not been approved by our Board of Directors.

While the foregoing provisions of our Certificate of Incorporation, Bylaws, Rights Agreement plan and Delaware law may have an anti-takeover effect, these provisions are intended to enhance the likelihood of continuity and stability in the composition of the Board of directors and in the policies formulated by the board of directors and to discourage certain types of transactions that may involve an actual or threatened change of control. In that regard, these provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our common stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

Exclusive forum for adjudication of disputes provision which limits the forum to the Delaware Court of Chancery for certain actions against the Company.

Our Bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the Delaware General Corporation Law , or (iv) any action asserting a claim governed by the internal affairs doctrine, except, in each case for claims arising under the Securities Act of 1933, as amended, the Exchange Act, or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction.

We believe limiting state law based claims to Delaware will provide the most appropriate outcomes as the risk of another forum misapplying Delaware law is avoided, Delaware courts have a well-developed body of case law and limiting the forum will preclude costly and duplicative litigation and avoids the risk of inconsistent outcomes. Additionally, Delaware Chancery Courts can typically resolve disputes on an accelerated schedule when compared to other forums. While we believe limiting the forum for state law based claims is a benefit, shareholders could be inconvenienced by not being able to bring certain actions in another forum they find favorable.

Delaware Takeover Statute

In general, Section 203 of the Delaware General Corporation Law prohibits a Delaware corporation that is a public company from engaging in any “business combination” (as defined below) with any “interested stockholder” (defined generally as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with such entity or person) for a period of three years following the date that such stockholder became an interested stockholder, unless: (1) prior to such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; (2) on consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (x) by persons who are directors and also officers and (y) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or (3) on or subsequent to such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 of the Delaware General Corporation Law defines “business combination” to include: (1) any merger or consolidation involving the corporation and the interested stockholder; (2) any sale, transfer, pledge or other disposition of ten percent or more of the assets of the corporation involving the interested stockholder; (3) subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; (4) any transaction involving the corporation that has the effect of increasing

the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or (5) the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

Scorpius Holdings, Inc. (formerly Nighthawk Biosciences, Inc.) is a contract development and manufacturing organization (“CDMO”) that provides a comprehensive range of services from process development to Current Good Manufacturing Practices (“CGMP”) clinical and commercial manufacturing of biologics for the biotechnology and biopharmaceutical industries through its Scorpius Biomanufacturing, Inc. (“Scorpius”) subsidiary. Its services include clinical and commercial drug substance manufacturing, release and stability testing and variety of process development services, including upstream and downstream development and optimization, analytical method development, cell line development, testing and characterization. The lead facility in San Antonio, TX commenced operations in September 2022.

During the past year, the Company’s priorities had shifted to biomanufacturing capabilities resulting in a refocusing of our resources towards our biomanufacturing efforts, deprioritizing our research efforts, divestment of non-cost assets, and clinical stage oncology assets including HS-110 and PTX-35. The Company also intends to continue discovery efforts of our subsidiary, Skunkworx, if it has sufficient resources.

Effective February 6, 2024, NightHawk Biologics, Inc. changed its name to Scorpius Holdings, Inc. (the “Company”) by filing a Certificate of Amendment (the “Certificate of Amendment”) to its Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware.

2.        Discontinued Operations

On December 27, 2023, NightHawk Biosciences, Inc. completed the sale of all of its assets and equity interest in Elusys Therapeutics, Inc. (“Elusys”)  to Elusys Holdings, a company controlled by our Chairman, Chief Executive Officer, and President, Jeffrey Wolf for approximately $2.5 million before working capital, escrow adjustments and transaction expenses.

Derecognition and Gain from Disposal of Discontinued Operations

As a result of the Elusys Therapeutics, Inc. sale and pursuant to the terms and conditions of the divestiture agreement entered into with Elusys Holdings, the Company ceased to have a financial interest in Elusys Therapeutics, Inc. as of December 27, 2023. Because the Company was selling all of its equity interest in Elusys Therapeutics, a wholly owned subsidiary that met the definition of a business, the Company considered deconsolidation guidance under ASC 810-10-40 Consolidation – Derecognition. The derecognition of Elusys Therapeutics requires the recognition of a gain or loss measured as the difference of fair value of consideration received (NCI is not applicable for Elusys) less the Company’s carrying value of Elusys Therapeutics. The Company concluded that the divestiture agreement was to be accounted for under derecognition guidance and required the company to record a gain on sale for the excess of consideration received over carrying value of assets derecognized and liabilities recognized.

Pursuant to the Agreement, Elusys Holdings was obligated to pay us $500,000 on December 11, 2023, which payment was timely completed. Elusys Holdings  is further obligated to pay to us on an annual basis a royalty fee equal to 3% of

gross revenue received by Elusys Holdings or any of its affiliates or their respective successors or licensees from all sales of the anthrax antitoxin known as ANTHIM® during the period commencing on January 1, 2024 and ending on June 30, 2031; provided that, if as of December 31, 2028, we have not received an aggregate of $5,000,000 in such royalty fees, Elusys Holdings  will be obligated to pay to us  no later than March 1, 2029 a cash payment equal to the difference between the aggregate amount of such royalty fees received by us  and $5,000,000.

Pursuant to the Agreement, at the December 27, 2023 closing of the Divestiture Transaction (the “Divestiture Closing”), Elusys Holdings assumed certain specified liabilities and manufacturing commitments relating to Elusys Therapeutics’ business, which at the time of the Divestiture were estimated at $51.4 million. The assumed liabilities and manufacturing commitments include all amounts owed to the former owners of Elusys Therapeutics under that certain Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) by and among us, Heat Acquisition Sub 1, Inc., Elusys Therapeutics and Fortis Advisors LLC, in its capacity as “Stockholders’ Representative,” which provides that we will remain liable if Elusys Holdings fails to satisfy its obligations to pay merger consideration under the Merger Agreement. In addition, from and after the Divestiture Closing, Elusys Holdings asumed all operating costs of Elusys Therapeutics, including the costs incurred after the closing related to Elusys Therapeutics employees, consultants, and regulatory and research costs. Mr. Wolf and William Ostrander, our Chief Financial Officer, will continue to serve in their current positions with us and also continue to serve as the Chief Executive Officer and Chief Financial Officer, respectively, of Elusys Holdings.

Also in connection with the transaction, we entered into a Shared Services Agreement with the Buyer setting forth the terms on which we will provide to Buyer, on a transitional basis, certain services or functions that it has historically provided to Elusys. Shared services will include various administrative, accounting, billing, cash management and banking and budgeting services and other support services. In consideration for such services, the Buyer will pay fees to us for the services provided, and those fees will generally be in amounts intended to allow us to recover all of its direct and indirect costs incurred in providing those services. We will charge the Buyer a fee for services performed by (i) our employees which shall be a percentage of each employee’s base salary based upon an allocation of their business time spent providing such services and (ii) third parties, the fees charged by such third parties. Buyer will also pay us for general and administrative expenses incurred by us attributable to both the operation of the Buyer and us (other than the provision of the services performed by us employees) and the provision of the shared services. As of December 31, 2023, no such services were provided.

The fair value of consideration received is shown in the following table:

	2023
Upfront cash consideration	$	500,000
Estimated fair value of 3% ANTHIM earnout	$	1,720,000
Estimated fair value of contingent consideration receivable, related party	$	268,000
Total fair value of contingent consideration receivable, related party	$	1,988,000
Total fair value of consideration received	$	2,488,000

Refer to “The Divestiture of Elusys Therapeutics, Inc.” for additional information on fair value assumptions of each contingent consideration. The book value of the assets and liabilities derecognized on December 27, 2023 in connection with the sale were as follows:

	2023
Cash	$	252,423
Prepaid expenses and deposits		30,228
Intangibles and other long-term assets		6,728,109

Accrued expenses and other liabilities		(1,183,129)
Contingent royalty earnout liability		(4,610,000)
Net book value of assets and liabilities sold	$	1,020,549

	2023
Total fair value of consideration received and receivable	$	2,488,000

3.        Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Scorpius Holdings, Inc., and its subsidiaries (“the Company” or “Scorpius”), Pelican Therapeutics, Inc. (“Pelican”), Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax, Inc., Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.), Scorpius Biomanufacturing, Inc. (formerly Scorpion Biological Services, Inc), Blackhawk Bio, Inc., and Abacus Biotech, Inc. The functional currency of the entities located outside the United States of America (the foreign entities) is the applicable local currency of the foreign entities. Assets and liabilities of the foreign entities are translated at period-end exchange rates. Statement of operations accounts are translated at the average exchange rate during the period. The effects of foreign currency translation adjustments are included in other comprehensive loss, which is a component of accumulated other comprehensive loss in stockholders’ equity. All significant intercompany accounts and transactions have been eliminated in consolidation. The December 31, 2023 and 2022 year-end financials include an 85% controlling interest in Pelican and a 94% controlling interest in Scorpius Holdings, Inc. Scorpius Holdings, Inc. accounts for its less than 100% interest in the consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Accordingly, the Company presents non-controlling interest as a component of stockholders’ equity on its consolidated balance sheets and reports non-controlling interest net loss under the heading “net loss – non-controlling interest” in the consolidated statements of operations and comprehensive loss.

Going Concern Uncertainty

The Company has an accumulated deficit of $254.4 million as of December 31, 2023 and a net loss of approximately $46.8 million for the year ended December 31, 2023 and has not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable future. The Company expects significant expenses in connection with its ongoing activities, particularly as the Company ramps up operations in its in-house bioanalytic, process development and manufacturing facility in San Antonio, TX. In addition, any new business ventures that the Company may engage in are likely to require commitments of capital. Accordingly, the Company will need to obtain substantial additional funding in connection with its planned operations. Adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it will be forced to delay, reduce or eliminate its research and development programs, any future commercialization efforts or the manufacturing services it plans to provide. To meet its

capital needs, the Company intends to continue to consider multiple alternatives, including, but not limited to, additional equity financings such as sales of its common stock under at-the-market offerings, debt financings, equipment sale leasebacks, partnerships, grants, funding collaborations and other funding transactions, if any are available. As of December 31, 2023, the Company had approximately $2.4 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

Risk and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, a small customer base with mostly short-term contracts, uncertainty of market acceptance of the Company’s service offerings, market competition from similar and larger sized CDMO companies, competitive pricing pressure, and dependence on key individuals and sole source suppliers.

The Company depends on third-party suppliers for key materials and services used in research and development, as well as manufacturing processes, and is subject to certain risks related to the loss of these third-party suppliers or their inability to supply adequate materials and services. If third-party suppliers do not supply raw materials on a timely basis, the Company’s manufacturing services may be delayed or canceled which would adversely impact our financial condition and results of operations. If our suppliers are non-compliant with the FDA’s quality system regulations or other applicable laws or regulations, the Company would be required to find alternative suppliers.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, useful lives of fixed assets, consideration receivable, other intangible assets, income taxes, stock-based compensation, right-of-use assets and lease liabilities, estimates used in divestiture accounting, and useful lives of intangible assets. Actual results may differ from those estimates.

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing  performance. To date, the CODM has viewed the operations and managed the business as one segment.

Cash and Cash Equivalents

The Company considers all cash and other highly liquid investments with initial maturities from the date of purchase of three months or less to be cash and cash equivalents.

Short-term Investments

The Company’s short-term investments are equity securities and are carried at their fair value based on quoted market prices. Realized and unrealized gains and losses on equity securities are included in net earnings in the period earned or incurred.

Derivative Financial Instruments

The Company has issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC 815 Derivatives and Hedging because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.”

The fair value of the warrants, including the warrants issued in connection with the January 2020 common stock offering and recorded as liability, was determined using the Monte Carlo simulation model, which is deemed to be an appropriate model due to the terms of the warrants issued. The fair value of warrants was affected by changes in inputs to the Monte Carlo simulation model including the Company’s stock price,expected stock price volatility, the remaining term, and the risk-free interest rate. This model uses Level 3 inputs, including stock pricevolatility, in the fair value hierarchy established by ASC 820 Fair Value Measurement. At December 31, 2023 the fair value of such warrants was $nil.

Concentration of Credit Risk

At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits. The Company has never experienced any losses related to these balances. As of December 31, 2023, there were no cash amounts in excess of $250,000. As of December 31, 2022, the uninsured balance was $7.8 million. The Company does not believe it is exposed to significant credit risk on cash and cash equivalents.

Property and Equipment

Property and equipment are stated at cost and are capitalized. Depreciation is calculated using the straight-line method and is based on estimated useful lives of five years for lab equipment, three years for computer equipment, eight years for furniture and fixtures and vehicles, and the lesser of the useful life or life of the lease for leasehold improvements.

Leases

The Company leases office space and certain equipment under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases. As such, the Company assesses all arrangements that convey the right to control the use of property, plant and equipment at inception to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset. When a modification to a lease occurs, the lease liability and right-of-use asset is remeasured based on the remaining lease payments and incremental borrowing rate as of the effective date of the modification.

Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the accompanying consolidated statements of operations and comprehensive loss.

The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

We do not record leases with terms of 12 months or less on the Consolidated Balance Sheets, and are expensed as incurred.

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during each year. Fully diluted net loss per share is computed using the weighted average number of common shares and dilutive securities outstanding during each year. Dilutive securities having an anti-dilutive effect on diluted loss per share are excluded from the calculation.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with ASC 740, Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employee directors using a fair value method that requires the recognition of compensation expense for costs related to all stock-based payments, including stock options and restricted stock units. The fair value method requires the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model. The fair value of restricted stock units is estimated based on the closing price of the Company’s stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for forfeitures as they occur. The Company settles exercises of stock options with newly issued shares of its common stock.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes-Merton option pricing model on the date of grant for stock options and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, and expected term. The expected volatility rates are estimated based on average historical stock price volatility of its own data. The expected term for the years ended December 31, 2023 and 2022 represents the average time that options are expected to be outstanding based on the average of the vesting term and the contractual term of the option. We account for forfeitures as they occur. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Net Loss Attributable to Non-controlling Interests

Net loss attributable to non-controlling interests is the result of the Company’s consolidation of subsidiaries of which it does not own 100%. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican, a related party prior to

acquisition, for 35,000 shares of the Company’s common stock. The stock exchange resulted in the Company owning 100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. Therefore, the Company’s net loss attributable to non-controlling interests relates to the 15% ownership of Pelican and 6% ownership of Scorpius Biomanufacturing that Scorpius does not own as of December 31, 2023 and 2022.

Deferred Revenue

Deferred revenue is comprised of biomanufacturing and process development customer deposits received in advance of our fulfillment of performance obligations.

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In-as-much as the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. As of December 31, 2023 and December 31, 2022, there was $0.03 million and $0.04 million of deferred revenue related to the Shattuck license agreement.

Process Development

Process development deferred revenue generally represents customer payments received in advance of the Company’s fulfillment of performance obligations associated with the custom development of a manufacturing process and analytical methods for a customer’s product. As of December 31, 2023 and December 31, 2022, there was $2.4 million and $1.6 million of deferred revenue related to process development, respectively.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price using the most likely method based on historical experience as well as applicable information currently available. Shipping and handling costs associated with inbound freight are capitalized to inventories and relieved through cost of sales as inventories are sold.

Shipping and handling costs associated with the delivery of products are included in selling, general and administrative expenses in our consolidated statements of income.

Payment terms and conditions vary by contract type, although terms generally require payment within 30 to 60 days of the invoice date. In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied; however, our contracts do not contain a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our

services, not to receive financing from our customers or to provide customers with financing. The Company has applied the practical expedient in ASC 606 and excludes information about a) remaining performance obligations that have an original expected duration of one year or less and b) transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. As of December 31, 2023, we do not have any unsatisfied performance obligations for contracts greater than one year.

Product Sales

The Company recognizes revenue from product sales when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. The Company invoices its customers after acceptance of the product and invoice payments are generally due within 30 days of the invoice date. The Company records product sales net of any variable consideration, including refund rights. The Company uses the most likely amount method when estimating its variable consideration, unless terms are specified within contracts. The Company recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period. These estimates may differ from actual consideration received. The Company evaluates these estimates to reflect known changes.

Grant Revenue

The Company recognizes revenue related to the Cancer Prevention and Research Institute of Texas (“CPRIT”) contract, which is being accounted for under Accounting Standards Update (“ASU”) No. 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made, as a conditional non-exchange contribution.

The CPRIT grant covered the period from June 1, 2017 through May 31, 2023, for a total grant award of up to $15.2 million. CPRIT advances grant funds upon request by the Company consistent with the agreed upon amounts and schedules as provided in the contract. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and the third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million was received in April 2023. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. When grant funds are received after costs have been incurred, the Company records revenue and a corresponding grants receivable until grant funds are received. As of December 31, 2023, all $15.2 million has been recognized and received.

License Revenue

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck Labs, Inc. (“Shattuck”) paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In March 2023, the Company received a milestone payment of $100,000 from Shattuck due to completion of a Phase 1A monotherapy dose escalation clinical trial of SL-172154. However, the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. See Note 18, “Subsequent Events.”

Process Development Revenue

Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an input method by tracking the progress toward completion based on the ratio of actual labor hours incurred to date to the Company’s estimated labor hours to complete. Under a process development contract, the customer owns the product details and process, which have no alternative use. Each process represents a distinct service that is sold

separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, the Company is entitled to consideration for progress to date that includes an element of profit margin.

The transaction price for services provided under the Company’s contracts reflects its best estimate of the amount of consideration to which it is entitled in exchange for providing goods and services to our customers. For contracts with multiple performance obligations, the Company allocates transaction price to each performance obligation identified in a contract on a relative standalone selling price basis. If observable standalone selling prices are not available, the Company estimates the applicable standalone selling price based on the pricing of other comparable services or on a price that the Company believes the market is willing to pay for the applicable service.

In determining the transaction price, the Company considers the different sources of variable consideration including, but not limited to, discounts, credits, refunds, price concessions or other similar items. The Company includes in the transaction price some or all of an amount of variable consideration, utilizing the most likely method, only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The actual amount of consideration ultimately received may differ.

Geographic Concentration

The Company attributes revenue to the individual countries where the customer is headquartered. The Company derived approximately 100% of its revenues from the United States during the year ended December 31, 2023 and approximately 94% of its revenues from Canada and approximately 6% of its revenues from the United States during the year ended December 31, 2022.

Business Combinations

The accounting for the Company’s business combinations consists of allocating the purchase price to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. The Company has up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to goodwill. Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among other factors, analysis of historical performance and estimates of future performance. The Company has used discounted cash flow analyses, which were based on its best estimate of future revenue, earnings and cash flows as well as its discount rate, adjusted for risk, and estimated attrition rates.

Goodwill and Intangible Assets

The Company classifies intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company determines the useful lives of definite-lived intangible assets after considering specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, and other economic facts; including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their estimated useful lives. Intangible assets that are deemed to have indefinite lives, including goodwill, are reviewed for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test for indefinite-lived intangibles, other than goodwill, consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill on an annual basis or when events or changes in circumstances indicate a potential impairment exists, using a fair value-based test. The Company records a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value. Refer to Note 9, “Goodwill and other intangible assets” of the Notes to Consolidated Financial Statements for additional information on impairment.

In-process research and development (“IPR&D”) assets acquired in a business combination are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that the Company acquires, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval and the ability to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of the carrying value of the IPR&D assets over fair value. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Contingent Consideration

Consideration paid or received as a result of a purchase or sale of a business may include potential future payments that are contingent upon the acquired business achieving certain milestones in the future (“contingent consideration”). Contingent consideration is measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, the estimated timing of milestone achievement, and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. The milestone payments will be made upon the achievement of milestones as well as royalty payments. Subsequent to the date of acquisition, the Company reassesses the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. Any adjustment to the contingent consideration will be recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration assets and liabilities expected to be settled within 12 months after the balance sheet date are presented in current asset and current liabilities sections, with the non-current portion recorded with other long-term assets and under long term liabilities in the consolidated balance sheets. As of December 31, 2023, there is $0.3 million of contingent consideration receivable, related party representing the fair value of future proceeds from the off-market issuance on a convertible note in Current assets and $1.7 million  contingent earn-out receivable, related party representing royalty payments on future revenue provided as purchase consideration from the divestiture of Elusys Therapeutics in long-term assets, both reported on the Consolidated Balance Sheet as of December 31, 2023. During the year ended December 31, 2022, $3.3 million of contingent consideration related to Pelican was

written off as PTX-35 will not continue on to a Phase 2 trial. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Cost of revenues and selling, general and administrative expenses

Cost of revenues consists of production wages, material costs and overhead, and other costs related to the recognition of revenue. Selling, general and administrative expenses consist of salaries and related costs for administrators, public company costs, business development personnel as well as legal, patent-related expenses and consulting fees. Public company costs include compliance, auditing services, tax services, insurance and investor relations.

Research and Development

Research and development expenses relate to our investments in additions and improvements to our manufacturing process, process development, and costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of the Company’s product candidates and other expenses relating to the design, development, testing and enhancement of its product candidates.

Accounts Receivable

Accounts receivable are primarily comprised of amounts owed to us for services and sales provided under our customer contracts and are recorded at the invoiced amount net of an allowance for credit losses, if necessary. The Company applies judgment in assessing the ultimate realization of our receivables and we estimate an allowance for credit losses based on various factors, such as the aging of our receivables, historical experience, and the financial condition of our customers.

Prepaid Expenses and Other Current Assets

The Company’s prepaid expenses and other current assets consist primarily of amounts paid in advance for manufacturing activities, clinical trial support, contract assets and insurance. Contract assets consist of unbilled receivables.

Discontinued Operations

In accordance with ASC Subtopic 205-20, Presentation of Financial Statements: Discontinued Operations, a disposal of a component of an entity or a group of components of an entity (“disposal group”) is required to be reported as discontinued operations if the disposal group represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the disposal group meets discontinued operations criteria. Assets and liabilities of disposal group meeting discontinued operations treatment is presented separately as held-for-sale. At the same time, the results of all discontinued operations, less applicable income taxes, are reported as components of net loss separate from the net loss of continuing operations.

Impact of Recently Issued Accounting Standards:

In December 2023, the FASB issued ASU 2023-09, which requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are evaluating the disclosure requirements related to the new standard.

In November 2023, the FASB issued ASU 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses, including for single reportable

segment entities. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. We are evaluating the disclosure requirements related to the new standard.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

5.        Fair Value of Financial Instruments

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level I – Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level II – Observable inputs, other than Level I prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The Company’s cash equivalents are classified within Level I of the fair value hierarchy.

As of December 31, 2023 and 2022, the fair values of cash and cash equivalents, accounts payable, and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. The Company’s short-term investments consist of Level I securities which are comprised of highly liquid mutual funds. The estimated fair value of the short-term investments was based on quoted market prices. There were no transfers between fair value hierarchy levels during the years ended December 31, 2023 or 2022.

The fair value of financial instruments measured on a recurring basis is as follows:

	As of December 31, 2023
Description	Total		Level 1			Level 2	Level 3
Assets:
Short-term investments	$	2,206,555	$	2,206,555	$	—	$	—

The following table summarizes the change in fair value, as determined by Level 3 inputs, for all assets and liabilities using unobservable Level 3 inputs for the year ended December 31, 2023:

The change in the fair value of the contingent consideration of ($0.1) million and ($0.1) million for the years ending December 31, 2023 and 2022, respectively, was primarily due to the change in timing and amount of the contract deferred consideration. The reclassification of ($4.6) million of contingent consideration for the year ending December 31, 2023 is due to the divestiture of Elusys Therapeutics, Inc. Therefore, the Company has separately reported the financial results of Elusys as discontinued operations in our consolidated statements of operations and comprehensive loss for the years ended December 31, 2023 and 2022, respectively, and presented the related assets and liabilities as of discontinued operations in the consolidated balance sheet as of December 31, 2022.

The change in fair value of contingent earn-out receivable, related party of $1.7 million for the year ended December 31, 2023 represents the fair value of contingent future royalty payments from Elusys Holdings, Inc. on potential future sales generated by Elusys Therapeutics, Inc., as part of the divestiture agreement.

The change in the fair value of the contingent consideration of ($3.3) million for the year ended December 31, 2022 was primarily due to the effect of the change in discount rate, probability of achieving milestones, passage of time on the fair

value measurement and discontinuation of the PTX-35 trial, thus leading to the write-off of the Pelican contingent consideration. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statement of operations and comprehensive loss.

The following table presents quantitative information about the inputs and valuation methodologies used for the Company’s fair value measurements of contingent consideration classified as Level 3 (which have now been reclassified to current liabilities of discontinued operations in our consolidated balance sheets) as of December 31, 2023 and December 31, 2022:

	As of December 31, 2023
	Valuation Methodology		Significant Unobservable Input		Weighted Average (range, if applicable)
Contingent consideration receivable, related party		Discounted Cash Flow Analysis

				Principal amount	$	2.25 million
	Valuation Methodology		Significant Unobservable Input		Weighted Average (range, if applicable)
Contingent earn-out receivable, related party		Discounted Cash Flow Analysis
				Timing of expected payments		2026-2029
				Discount rate		15.0%
				Future revenue projections	$	141.4 million
				Minimum earn-out payment		3% or $5.0 million
				Earn-out term through		December 31, 2028
	As of December 31, 2022
	Valuation Methodology		Significant Unobservable Input		Weighted Average (range, if applicable)
Elusys revenue earn-out		Discounted Cash Flow Analysis
				Timing of expected payments		2025-2036
				Discount rate		24.5%
				Future revenue projections	$	325.9 million
Elusys deferred contract consideration		Discounted Cash Flow Analysis
				Timing of expected payments		2023
				Discount rate		15.5%
				Future revenue projections	$	7.6 million

The Company records certain non-financial assets on a non-recurring basis, including goodwill and in-process R&D. This analysis requires significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital.

Acquisitions

6.        Acquisitions

Pelican Therapeutics

In 2017, the Company consummated the acquisition of 80% of the outstanding equity of Pelican, a related party, and Pelican became a majority owned subsidiary of the Company. During the quarter ended March 31, 2018, cash

consideration of approximately $300,000 was distributed to the participating Pelican stockholders and the remainder of approximately $200,000 for certain Pelican liabilities not satisfied was recognized as other income in the statements of operations and comprehensive loss for the period. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican. The stock exchange resulted in Heat increasing its controlling ownership in Pelican from 80% to 85%.

Under the agreement, the Company was also obligated to make future payments based on the achievement of certain clinical and commercialization milestones, as well as low single digit royalty payments and payments upon receipt of sublicensing income. However, due to the discontinuation of PTX-35 no future milestone payments are expected to be made. The goodwill and in-process R&D resulting from the acquisition were fully impaired as of December 31, 2022 (see Note 8).

Elusys Therapeutics

On April 18, 2022 (“Closing Date”), the Company closed on the acquisition of Elusys Therapeutics. Scorpius paid at the closing a cash upfront payment of $3,000,000 to the former owners (“Sellers”) of Elusys Therapeutics. Scorpius is obligated to pay the Sellers $2,000,000 of deferred cash consideration (“Merger Consideration”) at the same time that the payment of the receivable consideration is to be distributed to the Sellers as described below, which was paid in the second quarter of 2022. Earn out payments will be paid to the sellers for a period of 12 years from the date of the closing equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the closing date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded, or entered into during the first nine years after the Closing Date.

Per the merger agreement that was executed in connection with the acquisition of Elusys Therapeutics (the “Merger Agreement”), upon collection of the Elusys Therapeutics contract receivables of $24.5 million, The Company is obligated to remit payment of $22.3 million (the “Receivable Consideration”) to the Sellers. In April 2022, $20.8 million was remitted to the Sellers less a hold back of $1.5 million related to future fulfillment cost. Elusys Therapeutics  is expected to receive additional revenue from the future fulfillment of an existing U.S. Government contract, and the Company agreed to fulfill the future obligations of Elusys Therapeutics under such contract and pass through and distribute to the Sellers the payments received under such contract minus the costs associated with such fulfillment obligations, subject to certain adjustments to the Merger Consideration specified in the Merger Agreement, including income taxes payable with respect to such payments (the “Contract Deferred Consideration”). The Merger Agreement further provides that 80% of any amounts paid to and received by Elusys Therapeutics (the “Additional Earn Out”) after the Closing Date and prior to June 30, 2023, shall be paid to the Sellers, subject to certain adjustments specified in the Merger Agreement.

The Company acquired Elusys Therapeutics to expand its role in the biodefense space, complementing its focus to target emerging biological threats. The Company initially expected to leverage the capabilities of its potential Scorpius Biomanufacturing facility in Manhattan, Kansas, to manufacture Elusys Therapeutics’ therapies internally and therefore benefit from significant operating synergies, cost savings, as well as enhanced oversight, quality control, and speed to market.  However, the Company is unable to manufacture the Elusys Therapeutics’ therapies internally.  In addition, the Company has to date been unable to generate sufficient revenue from its current manufacturing facility or raise sufficient capital to enable it to build the biomanufacturing facility in Manhattan, Kansas and instead has been required to place contract with third parties for the manufacture of the Elusys Therapeutics’ therapies. See Note 11-Commitments and Contingencies.

The fair value of the purchase consideration was approximately $42.9 million. The purchase consideration consists of $3.0 million in cash and $2.0 million in deferred cash consideration, and the estimated fair value of the contingent and deferred consideration liabilities related to the receivable consideration, contract deferred consideration, earn out and additional earn out totaling $37.9 million. The valuation of the contract deferred consideration and earn out liabilities were valued using a discounted cash flow analysis that utilized discount rates of 24% and 14%, respectively. The value of the additional earn out liability was calculated as 80% of the estimated gross sales price of 1,500 pre-filled vials of ANTHIM®, less

estimated fulfillment costs to be incurred. The value of the receivable consideration was equal to the value of the contract receivables acquired, less holdback expenses, as this liability was settled within 30 days of the Closing Date.

The acquisition of Elusys Therapeutics was accounted for as a business combination and reflects the application of acquisition accounting in accordance with ASC 805, Business Combinations. The acquired Elusys Therapeutics’ assets, including identifiable intangible assets and liabilities assumed, have been recorded at their fair values with the excess purchase price assigned to goodwill. The recognition of goodwill is largely attributed to the value paid for Elusys Therapeutics’ capabilities, which will broaden the Company’s role in the biodefense space. The goodwill recorded for this transaction was valued at $3.9 million and will be deductible for tax purposes over 15 years.

The purchase price of $42.9 million has been allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was recorded as goodwill.

The following table highlights the components of the purchase consideration:

Aggregate consideration:
Cash consideration	$	3,000,000
Deferred cash consideration		2,000,000
Earn out		5,900,000
Additional earn out		4,735,000
Receivable consideration		22,318,685
Contract deferred consideration		4,900,000
Total purchase consideration	$	42,853,685

The purchase price allocation resulted in the following amounts being allocated to the assets acquired and liabilities assumed as of the closing date based on their respective fair values summarized below:

Purchase price allocation:
Cash and cash equivalents	$	5,719,899
Contract receivables		24,526,232

Goodwill and other intangible assets

9.        Goodwill and other intangible assets

The Company performs an annual impairment test at the reporting unit level as of April 1st of each fiscal year or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable.

Pelican Goodwill and In-Process R&D

Goodwill of $2.2 million and in-process R&D of $5.9 million were recorded in connection with the acquisition of Pelican, as described in Note 6 and have been allocated to the Pelican reporting unit. During the fourth quarter of 2021, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim impairment analysis using the income approach and in-process R&D with a total carrying value of $5.9 million was written down to its estimated fair value of $3.5 million and an impairment charge of $2.4 million during the fourth quarter of 2021 was recorded and goodwill in the amount of $1.5 million was fully impaired. During the third quarter of 2022, the Company elected to terminate any further development of PTX-35. As a result of the termination, the in-process R&D affiliated with PTX-35, in the amount of $3.5 million, has been fully impaired.

Elusys Therapeutics Goodwill and Intangible Assets

Goodwill of $3.3 million and an intangible asset of $9.7 million was recorded in connection with the acquisition of Elusys which has been allocated to the Elusys Therapeutics reporting unit. During the fourth quarter of 2022, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim goodwill impairment analysis using the income approach. However, through its quantitative analysis, the Company determined the carrying value was not in excess of its estimated fair value and therefore no impairment charge was recorded at December 31, 2022. Elusys Therapeutics’ intangible asset relates to the ANTHIM® formulation and is amortized over its remaining patent life, approximately 80 months. The Company’s annual impairment analysis was performed on April 1, 2023 using the income approach that determined the carrying value remained not in excess of its estimated fair value and, therefore, no impairment charge was necessary. During the second quarter of 2023, the Company finalized the purchase price allocation for the Elusys acquisition and recorded a measurement period adjustment that increased goodwill by approximately $0.6 million to a balance of $3.9 million.

As of September 30, 2023, the Company’s activities with regard to the divesture of the Elusys Therapeutics business met the criteria to report within discontinued operations. The Company has reclassified its previously issued financial statements to segregate the discontinued operations as of the earliest period presented. The Company evaluated its intangible asset and goodwill for impairment under ASC 360, Property, Plant, and Equipmment and ASC 350, Intangibles—Goodwill and Other. As a result, goodwill was fully impaired by $3.9 million and intangible assets were partially impaired by $2.3 million. These impairments resulted in the carrying value of the assets of discontinued operations being less than the fair value and therefore no loss has been recognized upon reclassification of the disposal group to discontinued operations treatment. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

The following table provides the Company’s goodwill, IPRD, and intangible assets as of December 31, 2023 and 2022:

In connection with the Merger Agreement for the acquisition of Elusys Therapeutics in April 2022, the Company agreed to pay earn out payments for a period of 12 years from the Closing Date equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the Closing Date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded or entered into during the first nine years after the Closing Date. The Merger Agreement also provides that the Company will remain liable for royalty payments if any buyer of Elusys Therapeutics fails to satisfy this obligation. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.Elusys relies on Lonza, a third-party manufacturer, to produce commercial quantities of its ANTHIM® bulk drug product requirements. Elusys has firm orders with Lonza for future purchases of bulk drug substance, with remaining total non-cancellable future commitments of approximately $51.4 million through 2025. If Elusys were to terminate certain firm orders with Lonza without cause, it will be required to pay for bulk drug substance scheduled for manufacture under its arrangement. This assumed manufacturing commitment was transferred to Elusys Holdings as part of the Divestiture Transation. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023, with Elusys Holdings, Inc. (“Elusys Holdings”), Elusys Holdings purchased from the Company a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”), the conversion of which is subject to both Elusys’ Holdings election and obtaining stockholder approval of the issuance of shares of the Company’s common stock upon such conversion. The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of the Company’s common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of the Company’s common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of the Company’s common stock upon conversion of the Note.

Grant Revenue

In June 2016, Pelican entered into a cancer research grant contract (“Grant Contract”) with CPRIT, under which CPRIT awarded a grant not to exceed $15.2 million for use in developing cancer treatments by targeting a novel T-cell costimulatory receptor (namely, DR3/TNFRSF25). The Grant Contract initially covered a period from June 1, 2016 through November 30, 2019, as amended, was extended to May 30, 2022. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and a third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million was received in April 2023. As of December 31, 2023, all $15.2 million has been recognized and received.

The grant was subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to provide $7.6 million in matching funds over the life of the project. Upon commercialization of the product, the terms of the grant require Pelican to pay tiered royalties in the low to mid-single digit percentages. Such royalties reduce to less than one percent after a mid-single-digit multiple of the grant funds have been paid to CPRIT in royalties.

License revenue

In June 2016, Scorpius licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases with Shattuck. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In March 2023, the Company received a milestone payment of $100,000 from Shattuck due to completion of a Phase 1A monotherapy dose escalation clinical trial of SL-172154. Refer to Note 19, “Subsequent Events,” for additional information about the subsequent sale of the Shattuck license.

Process Development Revenue

During the years ended December 31, 2023 and 2022, the Company recognized $6.6 million and $0.1 million of process development revenue, respectively. Revenue was primarily derived from two customers who represented 86% of total recognized process development revenue for the year ended December 31, 2023. One customer accounted for 74% of process development revenue for the fiscal year ended December 31, 2023, and is migrating to a larger CDMO for commcrcial manufacture of their product.

The following table presents changes in contract liabilities for the years ended December 31, 2023 and 2022:

Accounting for Stock-Based Compensation:

Stock Options - Under the Plans, we have issued stock options. A stock option granted gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined exercise price for a specific period of time. The exercise price is determined by the closing stock price on the date of the grant. We typically issue options that vest over four years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plans, the contractual life of the option grants may not exceed ten years. During the years ended December 31, 2023, and 2022, we issued options that expire ten years from the date of grant. No stock options were granted during the year December 31, 2023.

Fair Value Determination - We have used the Black-Scholes-Merton option pricing model to determine fair value of our stock option awards on the date of grant.

The following weighted-average assumptions were used for option grants during the years ended December 31, 2023:

● Volatility – The Company used an average historical stock price volatility of its own data.

● Expected life of options – The expected term represents the period that the Company’s stock option grants are expected to be outstanding. The Company elected to utilize the “simplified” method to estimate the expected term as the company does not have sufficient appropriate exercise data on which to base its estimate. Under this approach, the weighted-average expected life is presumed to be the average of the vesting term and the contractual term of the option.

● Risk-free interest rate – The rate is based on U.S. Treasury interest rates at the time of the grant whose term is consistent with the expected life of the stock options.

● Dividend yield – The expected dividend yield was considered to be 0% in the option pricing formula since the Company had not paid any dividends and had no plan to do so in the future.

● Forfeitures – The Company’s policy is to account for forfeitures as they occur.

The following table summarizes assumptions used in our calculations of fair value for the year ended December 31, 2022. No stock options were granted during the year ended December 31, 2023.

	2022
Dividend yield	—	%
Expected volatility	100.85-105.09	%
Risk-free interest rate	1.95-3.61	%
Expected lives (years)	5.3-6.1	years

Stock Option Activity – No stock options were granted during the year ended December 31, 2023. The weighted-average grant date fair value of options granted during the year ended December 31, 2022 was $0.87.

The following table summarizes stock option activity for the years ended December 31, 2023 and 2022:

Unrecognized compensation expense related to unvested stock options was $2.0 million as of December 31, 2023, which is expected to be recognized over a weighted-average period of 1.00 years and will be adjusted for forfeitures as they occur.

Restricted Stock - Under the Plans, the Company has issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors and Executives vest 50% on the grant date, 30% on the first anniversary and 10% each anniversary thereafter. The grant date fair value of the restricted stock is equal to the closing market price of the Company’s common stock on the date of grant.

Restricted Stock Activity - The following table summarizes the restricted stock activity during the years ended December 31, 2023 and 2022:

The aggregate fair value of awards that vested during the years ended December 31, 2023 and 2022 was $0.1 million and $1.6 million, respectively.

RSUs - Under the Plans, the Company has time-based RSUs. RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has no voting rights until the RSUs vest. The employees' time-based RSUs will result in the delivery of shares in pro-rata increments commencing on the award date. The grant date fair value of the RSUs is equal to the closing market price of the Company’s common stock on the grant date. The Company recognizes the grant date fair value of RSUs of shares it expects to issue as compensation expense ratably over the requisite service period.

At December 31, 2023 and December 31, 2022, the Company evaluated all significant available positive and negative evidence, including the existence of losses in recent years and management’s forecast of future taxable income, and, as a result, determined it was more likely than not that federal, foreign, and state deferred tax assets, including benefits related to net operating loss carryforwards, would not be realized. Accordingly, the deferred tax assets have been fully offset by a valuation allowance of $40.5 milion and $32.6 million as of December 31, 2023 and 2022, respectively.

As of December 31, 2023, and 2022, the Company’s U.S. federal net operating loss (“NOL”) carryforwards were approximately $197.0 million and $174.3 million, respectively. However, due to Section 382 limitations, only $136.3 million of the NOLs are available to offset future taxable income. Of the $136.3 million of available federal net operating loss carryforwards, $128.2 million were incurred after December 31, 2017 and therefore, will not expire. The remaining $8.1 million of available federal net operating loss carryforwards begin to expire in 2029. As of December 31, 2023, and 2022, the Company had state NOL carryforwards of approximately $126.5 million and $124.5 million, respectively. Due to Section 382 limitations, only $2.8 million of the state NOLs are available to offset future taxable income. The state net operating losses that are available to offset future taxable income begin to expire in 2032.

The Company’s ability to utilize its NOL and research and development (R&D) credit carryforwards may be substantially limited due to ownership changes that have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain stockholders or public groups. The Company completed a Section 382 study during 2021. It was determined that the Company has experienced five ownership changes of over 50% since 2013, the latest occurring on June 30, 2020. Going forward, the utilization of loss carryforwards and tax credits generated before June 30, 2020 will be subject to an annual limitation. As a result of the ownership changes and limitations, $58.2 million of federal NOLs

and $2.9 million of federal R&D credits will expire unutilized, in addition to Section 382 limits on Pelican already in place.

The Company has evaluated its tax positions to consider whether it has any unrecognized tax benefits. As of December 31, 2023, the Company had no unrecognized tax benefits. The Company does not anticipate a significant change in total unrecognized tax benefits or the Company’s effective tax rate due to the settlement of audits or the expiration of statutes of limitations within the next twelve months. Furthermore, the Company does not expect any cash settlement with the taxing authorities as a result of these unrecognized tax benefits as the Company has sufficient unutilized carryforward attributes to offset the tax impact of these adjustments.

The following is a tabular reconciliation of the Company’s change in gross unrecognized tax positions at December 31, 2023:

	2023		2022
Beginning balance	$	—	$	—
Gross increases for tax positions related to the acquisition of Elusys Therapeutics		1,480,974		—
Gross increases for tax positions related to the current periods		-		—
Divestiture of equity interests in ElusysTherapeutics		(1,480,974)		—
Ending balance	$	—	$	—

The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions as of December 31, 2023 and 2022 that would impact the effective tax rate if recognized, and as such, no interest or penalties were recorded to income tax expense.

The Company has analyzed its filing positions in all significant federal, state, and foreign jurisdictions where it is required to file income tax returns, as well as open tax years in these jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, and local tax examinations by tax authorities for years before 2020, although carryforward attributes that were generated prior to 2020 may still be adjusted upon examination by the taxing authorities if they either have been or will be used in a future period. No income tax returns are currently under examination by taxing authorities.

15. Leases

The Company accounts for its leases under ASC 842, “Leases”. The Company has determined that its leases for office and laboratory space without optional terms or variable components are operating leases.

The Company conducts its operations from leased facilities in Morrisville, North Carolina; San Antonio, Texas; and North Brunswick, New Jersey. The North Carolina lease will expire in 2030, the Texas lease will expire last in 2038, the New Brunswick leases will expire in July 2024. The leases are for general office space, manufacturing space, and lab space and require the Company to pay property taxes, insurance, common area expenses and maintenance costs.

In June 2021, the Company entered into a lease agreement with Durham KTP Tech 7, LLC, to lease a 15,996 square foot facility in Morrisville, North Carolina to expand its research and development activities. The lease has a term of eight years following the commencement date and provides the Company the option to extend the lease term for one five year term, however option to extend was not included in the ROU asset and liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. Scorpius,, upon commencement, recorded an operating lease right-of-use asset of $5.6 million and lease liability of $3.2 million for this lease in the accompanying consolidated balance sheets.

In October 2021, Scorpius entered into a lease agreement with Merchants Ice II, LLC to lease a 20,144 square foot facility in San Antonio, TX for general office, laboratory, research, analytical, and/or biomanufacturing purposes. Merchants Ice II, LLC is a nonprofit entity investing in the building with the intention to encourage development of emerging technologies. As a result, investments made by both Merchants Ice II, LLC and Scorpius into the building may qualify and share tax credits under the New Market Tax Credit (“NMTC”) program. Scorpius agreed that all investments and expenditures qualifying under the NMTC (i.e., certain equipment and building improvements) would be purchased by Merchants Ice II, LLC to generate the largest possible tax incentive and Scorpius would reimburse Merchants Ice II, LLC

for these payments. The lease officially commenced on September 15, 2022. As of December 31, 2022, Scorpius has reimbursed Merchants Ice II, LLC $24.3 million. Based on ASC 842, Scorpius has capitalized $13.2 million of the reimbursements as lab equipment, expensed $0.9 million as supplies and facilities, and $10.2 million has been included in the finance lease right-of-use asset. In 2023, additional NMTC tax credit payments totalling $3.1 million were received which resulted in a lease modification. The ROU asset and liability were adjusted to reflect the impacts of the modification. The lease has a term of fifteen years following the commencement date and provides Scorpius the option to extend the lease term for one fifteen-year term, and one subsequent ten year term upon expiration of the first extended term. These options to extend were not included in the ROU asset and lease liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. Scorpius upon commencement, recorded a finance lease right-of-use asset of $15.1 million and lease liability of $5.1 million for this lease in the accompanying consolidated balance sheets.

In December 2022, Scorpius entered into a lease agreement with TPB Merchants Ice LLC to lease a 8,042 square foot facility in San Antonio, TX for general office, laboratory, and/or biomanufacturing purposes. The lease has a term of fifteen years following the commencement date and provides the Company the option to extend the lease term for one ten year term, however option to extend was not included in the ROU asset and liability. It is subject to fixed rate escalation increases and provided up to $0.5 million for tenant improvements. The lease commenced in May 2023 and Scorpius recorded a finance lease right-of-use asset of $7.8 million and lease liability of $2.3 million for this lease in the accompanying consolidated balance sheets.

In December 2023, Scorpius entered into a lease agreement with EastGroup Properties, L.P. to lease a 22,262 square foot facility in San Antonio, TX for general office and warehouse purposes. The lease has a term of five years following the commencement date. It is subject to fixed rate escalation increases and provided up to $0.1 million for tenant improvements. Scorpius recorded a operating lease right-of-use asset of $0.9 million and lease liability of $1.0 million for this lease in the accompanying consolidated balance sheets.

Total cash paid for operating leases during the years ended December 31, 2023 and 2022 was $0.8 million and $0.8 million and is included within cash flows from operating activities within the consolidated statements of cash flows.

The Company leases furniture and specialized lab equipment under finance leases. The related ROU assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the asset. For the year ended December 31, 2023, additional finance equipment leases commenced and right-of-use assets of $2.2 million were recorded, and modifications to finance equipment leases were obtained totalling $0.07 million. Both are included within the supplemental disclosure for cash flow within the consolidated statements of cash flows.

Net Loss Per Share

17.        Net Loss Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Fully diluted net loss per common share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the periods. Common equivalent shares consist of stock options, restricted stock units, and warrants that are computed using the treasury stock method.

For the years ended December 31, 2023 and 2022, all of the Company’s common stock options, unvested restricted stock units and warrants are anti-dilutive and therefore have been excluded from the diluted net loss per common share calculation.

The following table reconciles net loss to net loss attributable to Scorpius Holdings, Inc.:

On January 26, 2024 in accordance with the terms of that certain Asset and Equity Interests Purchase Agreement, dated December 11, 2023, with Elusys Holdings, Inc. (“Elusys Holdings”),  Elusys Holdings purchased from us a convertible promissory note in the aggregate amount of $2,250,000 (the “Note”). The Note bears interest at a rate of 1% per annum, matures on the one-year anniversary of its issuance and converts into shares of our common stock at the option of Elusys Holdings only if stockholder approval of the issuance of such shares of common stock issuable upon conversion of the Note is obtained prior to the maturity date. The conversion price is $0.39109, which is equal to 110% of the volume weighted average price (VWAP) of our common stock for the seven trading days prior to December 11, 2023. Based upon such conversion price Elusys Holdings would be issued 5,810,740 shares of our common stock upon conversion of the Note. The cash proceeds for the Note were received on January 26, 2024.

On January 29, 2024, we entered into a Patent Rights Sale and Assignment Agreement with Kopfkino IP, LLC (“Patent Agreement”).

Summary of Significant Accounting Policies

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Scorpius Holdings, Inc., and its subsidiaries (“the Company” or “Scorpius”), Pelican Therapeutics, Inc. (“Pelican”), Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax, Inc., Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.), Scorpius Biomanufacturing, Inc. (formerly Scorpion Biological Services, Inc), Blackhawk Bio, Inc., and Abacus Biotech, Inc. The functional currency of the entities located outside the United States of America (the foreign entities) is the applicable local currency of the foreign entities. Assets and liabilities of the foreign entities are translated at period-end exchange rates. Statement of operations accounts are translated at the average exchange rate during the period. The effects of foreign currency translation adjustments are included in other comprehensive loss, which is a component of accumulated other comprehensive loss in stockholders’ equity. All significant intercompany accounts and transactions have been eliminated in consolidation. The December 31, 2023 and 2022 year-end financials include an 85% controlling interest in Pelican and a 94% controlling interest in Scorpius Holdings, Inc. Scorpius Holdings, Inc. accounts for its less than 100% interest in the consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Accordingly, the Company presents non-controlling interest as a component of stockholders’ equity on its consolidated balance sheets and reports non-controlling interest net loss under the heading “net loss – non-controlling interest” in the consolidated statements of operations and comprehensive loss.

Going Concern Uncertainty

Going Concern Uncertainty

The Company has an accumulated deficit of $254.4 million as of December 31, 2023 and a net loss of approximately $46.8 million for the year ended December 31, 2023 and has not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable future. The Company expects significant expenses in connection with its ongoing activities, particularly as the Company ramps up operations in its in-house bioanalytic, process development and manufacturing facility in San Antonio, TX. In addition, any new business ventures that the Company may engage in are likely to require commitments of capital. Accordingly, the Company will need to obtain substantial additional funding in connection with its planned operations. Adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it will be forced to delay, reduce or eliminate its research and development programs, any future commercialization efforts or the manufacturing services it plans to provide. To meet its

capital needs, the Company intends to continue to consider multiple alternatives, including, but not limited to, additional equity financings such as sales of its common stock under at-the-market offerings, debt financings, equipment sale leasebacks, partnerships, grants, funding collaborations and other funding transactions, if any are available. As of December 31, 2023, the Company had approximately $2.4 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

Risk and Uncertainties

Risk and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, a small customer base with mostly short-term contracts, uncertainty of market acceptance of the Company’s service offerings, market competition from similar and larger sized CDMO companies, competitive pricing pressure, and dependence on key individuals and sole source suppliers.

The Company depends on third-party suppliers for key materials and services used in research and development, as well as manufacturing processes, and is subject to certain risks related to the loss of these third-party suppliers or their inability to supply adequate materials and services. If third-party suppliers do not supply raw materials on a timely basis, the Company’s manufacturing services may be delayed or canceled which would adversely impact our financial condition and results of operations. If our suppliers are non-compliant with the FDA’s quality system regulations or other applicable laws or regulations, the Company would be required to find alternative suppliers.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, useful lives of fixed assets, consideration receivable, other intangible assets, income taxes, stock-based compensation, right-of-use assets and lease liabilities, estimates used in divestiture accounting, and useful lives of intangible assets. Actual results may differ from those estimates.

Segments

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing  performance. To date, the CODM has viewed the operations and managed the business as one segment.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all cash and other highly liquid investments with initial maturities from the date of purchase of three months or less to be cash and cash equivalents.

Short-term Investments

Short-term Investments

The Company’s short-term investments are equity securities and are carried at their fair value based on quoted market prices. Realized and unrealized gains and losses on equity securities are included in net earnings in the period earned or incurred.

Derivative Financial Instruments

Derivative Financial Instruments

The Company has issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC 815 Derivatives and Hedging because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.”

The fair value of the warrants, including the warrants issued in connection with the January 2020 common stock offering and recorded as liability, was determined using the Monte Carlo simulation model, which is deemed to be an appropriate model due to the terms of the warrants issued. The fair value of warrants was affected by changes in inputs to the Monte Carlo simulation model including the Company’s stock price,expected stock price volatility, the remaining term, and the risk-free interest rate. This model uses Level 3 inputs, including stock pricevolatility, in the fair value hierarchy established by ASC 820 Fair Value Measurement. At December 31, 2023 the fair value of such warrants was $nil.

Concentration of Credit Risk

Concentration of Credit Risk

At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits. The Company has never experienced any losses related to these balances. As of December 31, 2023, there were no cash amounts in excess of $250,000. As of December 31, 2022, the uninsured balance was $7.8 million. The Company does not believe it is exposed to significant credit risk on cash and cash equivalents.

Property and Equipment

Property and Equipment

Property and equipment are stated at cost and are capitalized. Depreciation is calculated using the straight-line method and is based on estimated useful lives of five years for lab equipment, three years for computer equipment, eight years for furniture and fixtures and vehicles, and the lesser of the useful life or life of the lease for leasehold improvements.

Leases

Leases

The Company leases office space and certain equipment under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases. As such, the Company assesses all arrangements that convey the right to control the use of property, plant and equipment at inception to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset. When a modification to a lease occurs, the lease liability and right-of-use asset is remeasured based on the remaining lease payments and incremental borrowing rate as of the effective date of the modification.

Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the accompanying consolidated statements of operations and comprehensive loss.

The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

We do not record leases with terms of 12 months or less on the Consolidated Balance Sheets, and are expensed as incurred.

Net Loss per Share

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during each year. Fully diluted net loss per share is computed using the weighted average number of common shares and dilutive securities outstanding during each year. Dilutive securities having an anti-dilutive effect on diluted loss per share are excluded from the calculation.

Income Tax

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with ASC 740, Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations.

Stock-Based Compensation

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employee directors using a fair value method that requires the recognition of compensation expense for costs related to all stock-based payments, including stock options and restricted stock units. The fair value method requires the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model. The fair value of restricted stock units is estimated based on the closing price of the Company’s stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for forfeitures as they occur. The Company settles exercises of stock options with newly issued shares of its common stock.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes-Merton option pricing model on the date of grant for stock options and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, and expected term. The expected volatility rates are estimated based on average historical stock price volatility of its own data. The expected term for the years ended December 31, 2023 and 2022 represents the average time that options are expected to be outstanding based on the average of the vesting term and the contractual term of the option. We account for forfeitures as they occur. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Net Loss Attributable to Non-controlling Interests

Net Loss Attributable to Non-controlling Interests

Net loss attributable to non-controlling interests is the result of the Company’s consolidation of subsidiaries of which it does not own 100%. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican, a related party prior to

acquisition, for 35,000 shares of the Company’s common stock. The stock exchange resulted in the Company owning 100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. Therefore, the Company’s net loss attributable to non-controlling interests relates to the 15% ownership of Pelican and 6% ownership of Scorpius Biomanufacturing that Scorpius does not own as of December 31, 2023 and 2022.

Deferred Revenue

Deferred Revenue

Deferred revenue is comprised of biomanufacturing and process development customer deposits received in advance of our fulfillment of performance obligations.

License Agreements

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In-as-much as the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. As of December 31, 2023 and December 31, 2022, there was $0.03 million and $0.04 million of deferred revenue related to the Shattuck license agreement.

Process Development

Process development deferred revenue generally represents customer payments received in advance of the Company’s fulfillment of performance obligations associated with the custom development of a manufacturing process and analytical methods for a customer’s product. As of December 31, 2023 and December 31, 2022, there was $2.4 million and $1.6 million of deferred revenue related to process development, respectively.

Revenue Recognition

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price using the most likely method based on historical experience as well as applicable information currently available. Shipping and handling costs associated with inbound freight are capitalized to inventories and relieved through cost of sales as inventories are sold.

Shipping and handling costs associated with the delivery of products are included in selling, general and administrative expenses in our consolidated statements of income.

Payment terms and conditions vary by contract type, although terms generally require payment within 30 to 60 days of the invoice date. In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied; however, our contracts do not contain a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our

services, not to receive financing from our customers or to provide customers with financing. The Company has applied the practical expedient in ASC 606 and excludes information about a) remaining performance obligations that have an original expected duration of one year or less and b) transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. As of December 31, 2023, we do not have any unsatisfied performance obligations for contracts greater than one year.

Product Sales

The Company recognizes revenue from product sales when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. The Company invoices its customers after acceptance of the product and invoice payments are generally due within 30 days of the invoice date. The Company records product sales net of any variable consideration, including refund rights. The Company uses the most likely amount method when estimating its variable consideration, unless terms are specified within contracts. The Company recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period. These estimates may differ from actual consideration received. The Company evaluates these estimates to reflect known changes.

Grant Revenue

The Company recognizes revenue related to the Cancer Prevention and Research Institute of Texas (“CPRIT”) contract, which is being accounted for under Accounting Standards Update (“ASU”) No. 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made, as a conditional non-exchange contribution.

The CPRIT grant covered the period from June 1, 2017 through May 31, 2023, for a total grant award of up to $15.2 million. CPRIT advances grant funds upon request by the Company consistent with the agreed upon amounts and schedules as provided in the contract. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and the third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million was received in April 2023. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. When grant funds are received after costs have been incurred, the Company records revenue and a corresponding grants receivable until grant funds are received. As of December 31, 2023, all $15.2 million has been recognized and received.

License Revenue

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck Labs, Inc. (“Shattuck”) paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In March 2023, the Company received a milestone payment of $100,000 from Shattuck due to completion of a Phase 1A monotherapy dose escalation clinical trial of SL-172154. However, the technology that the Company out-licensed remains in the early stages of development since there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any additional future revenue from Shattuck. See Note 18, “Subsequent Events.”

Process Development Revenue

Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an input method by tracking the progress toward completion based on the ratio of actual labor hours incurred to date to the Company’s estimated labor hours to complete. Under a process development contract, the customer owns the product details and process, which have no alternative use. Each process represents a distinct service that is sold

separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, the Company is entitled to consideration for progress to date that includes an element of profit margin.

The transaction price for services provided under the Company’s contracts reflects its best estimate of the amount of consideration to which it is entitled in exchange for providing goods and services to our customers. For contracts with multiple performance obligations, the Company allocates transaction price to each performance obligation identified in a contract on a relative standalone selling price basis. If observable standalone selling prices are not available, the Company estimates the applicable standalone selling price based on the pricing of other comparable services or on a price that the Company believes the market is willing to pay for the applicable service.

In determining the transaction price, the Company considers the different sources of variable consideration including, but not limited to, discounts, credits, refunds, price concessions or other similar items. The Company includes in the transaction price some or all of an amount of variable consideration, utilizing the most likely method, only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The actual amount of consideration ultimately received may differ.

Geographic Concentration

Geographic Concentration

The Company attributes revenue to the individual countries where the customer is headquartered. The Company derived approximately 100% of its revenues from the United States during the year ended December 31, 2023 and approximately 94% of its revenues from Canada and approximately 6% of its revenues from the United States during the year ended December 31, 2022.

Business Combinations

Business Combinations

The accounting for the Company’s business combinations consists of allocating the purchase price to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. The Company has up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to goodwill. Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among other factors, analysis of historical performance and estimates of future performance. The Company has used discounted cash flow analyses, which were based on its best estimate of future revenue, earnings and cash flows as well as its discount rate, adjusted for risk, and estimated attrition rates.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

The Company classifies intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company determines the useful lives of definite-lived intangible assets after considering specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, and other economic facts; including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their estimated useful lives. Intangible assets that are deemed to have indefinite lives, including goodwill, are reviewed for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test for indefinite-lived intangibles, other than goodwill, consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill on an annual basis or when events or changes in circumstances indicate a potential impairment exists, using a fair value-based test. The Company records a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value. Refer to Note 9, “Goodwill and other intangible assets” of the Notes to Consolidated Financial Statements for additional information on impairment.

In-process research and development (“IPR&D”) assets acquired in a business combination are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that the Company acquires, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval and the ability to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of the carrying value of the IPR&D assets over fair value. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Contingent Consideration

Contingent Consideration

Consideration paid or received as a result of a purchase or sale of a business may include potential future payments that are contingent upon the acquired business achieving certain milestones in the future (“contingent consideration”). Contingent consideration is measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, the estimated timing of milestone achievement, and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. The milestone payments will be made upon the achievement of milestones as well as royalty payments. Subsequent to the date of acquisition, the Company reassesses the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. Any adjustment to the contingent consideration will be recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration assets and liabilities expected to be settled within 12 months after the balance sheet date are presented in current asset and current liabilities sections, with the non-current portion recorded with other long-term assets and under long term liabilities in the consolidated balance sheets. As of December 31, 2023, there is $0.3 million of contingent consideration receivable, related party representing the fair value of future proceeds from the off-market issuance on a convertible note in Current assets and $1.7 million  contingent earn-out receivable, related party representing royalty payments on future revenue provided as purchase consideration from the divestiture of Elusys Therapeutics in long-term assets, both reported on the Consolidated Balance Sheet as of December 31, 2023. During the year ended December 31, 2022, $3.3 million of contingent consideration related to Pelican was

written off as PTX-35 will not continue on to a Phase 2 trial. Refer to Note 2, “Discontinued Operations” of the Notes to Consolidated Financial Statements for additional information.

Cost of revenues and selling, general and administrative expense

Cost of revenues and selling, general and administrative expenses

Cost of revenues consists of production wages, material costs and overhead, and other costs related to the recognition of revenue. Selling, general and administrative expenses consist of salaries and related costs for administrators, public company costs, business development personnel as well as legal, patent-related expenses and consulting fees. Public company costs include compliance, auditing services, tax services, insurance and investor relations.

Research and Development

Research and Development

Research and development expenses relate to our investments in additions and improvements to our manufacturing process, process development, and costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of the Company’s product candidates and other expenses relating to the design, development, testing and enhancement of its product candidates.

Accounts Receivable

Accounts Receivable

Accounts receivable are primarily comprised of amounts owed to us for services and sales provided under our customer contracts and are recorded at the invoiced amount net of an allowance for credit losses, if necessary. The Company applies judgment in assessing the ultimate realization of our receivables and we estimate an allowance for credit losses based on various factors, such as the aging of our receivables, historical experience, and the financial condition of our customers.

Prepaid Expenses and Other Current Assets

Prepaid Expenses and Other Current Assets

The Company’s prepaid expenses and other current assets consist primarily of amounts paid in advance for manufacturing activities, clinical trial support, contract assets and insurance. Contract assets consist of unbilled receivables.

Discontinued Operations

Discontinued Operations

In accordance with ASC Subtopic 205-20, Presentation of Financial Statements: Discontinued Operations, a disposal of a component of an entity or a group of components of an entity (“disposal group”) is required to be reported as discontinued operations if the disposal group represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the disposal group meets discontinued operations criteria. Assets and liabilities of disposal group meeting discontinued operations treatment is presented separately as held-for-sale. At the same time, the results of all discontinued operations, less applicable income taxes, are reported as components of net loss separate from the net loss of continuing operations.

Impact of Recently Adopted Accounting Standards

Impact of Recently Issued Accounting Standards:

In December 2023, the FASB issued ASU 2023-09, which requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are evaluating the disclosure requirements related to the new standard.

In November 2023, the FASB issued ASU 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses, including for single reportable

segment entities. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. We are evaluating the disclosure requirements related to the new standard.
