ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis is intended to provide a narrative of our financial results and an evaluation of our results of operations and financial condition. The discussion should be read in conjunction with our consolidated financial statements, the related notes to the financial statements, and our Annual Report on Form 10-K for the year ended December 31, 2024.

In addition to historical information, this discussion contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, regarding the Company’s expectations concerning its future operations, earnings and prospects. On the date the forward-looking statements are made, the statements represent the Company’s expectations, but the expectations concerning its future operations, earnings and prospects may change. The Company’s expectations involve risks and uncertainties and are based on many assumptions that the Company believes to be reasonable, but such assumptions may ultimately prove to be inaccurate or incomplete, in whole or in part. Accordingly, there can be no assurances that the Company’s expectations and the forward-looking statements will be correct. Please refer to Part I, Item 1A (“Risk Factors”) of this Annual Report on Form 10-K for a description of risk factors that could cause actual results to differ from the expectations stated in this discussion. Odyssey disclaims any obligation to update any of these forward-looking statements except as required by law.

Operational Update

Additional information regarding our announced projects can be found in Part I, Item 1 of this Annual Report on Form 10-K for the year ended December 31, 2024. Only projects that are material in nature or with material status updates are discussed below. We may have other projects in various stages of planning or execution that may not be disclosed for security or legal reasons until considered appropriate by management or required by law.

Our subsea project portfolio contains multiple projects in various stages of development throughout the world and across different mineral resources. We regularly evaluate prospective resources to identify new projects. In addition to conducting geological assessments, we also analyze licensing regulations to assure rights can be secured, business development models, and commercial viability factors; all which factor into our decision making on whether and how to pursue opportunities in the best interest of our stockholders.

Subsea Mineral Exploration Projects

ExO Phosphate Project:

The “Exploraciones Oceánicas” Phosphate Project is a rich deposit of phosphate sands located 70-90 meters deep within Mexico’s Exclusive Economic Zone (“EEZ”). This deposit contains a large amount of high-grade phosphate ore that can be extracted on a financially attractive basis (essentially a standard dredging operation). The product will be desirable to Mexican and other world producers of fertilizers and can provide important benefits to Mexico’s agricultural development.

The deposit lies within an exclusive mining concession licensed to the Mexican company Exploraciones Oceánicas S. de R.L. de CV (“ExO”). Oceanica Resources, S. de R.L., a Panamanian company (“Oceanica”) owns 99.99% of ExO, and Odyssey owns 56.14% of Oceanica through Odyssey Marine Enterprises, Ltd., a wholly owned Bahamian company (“Enterprises”).

In 2012, ExO was granted a 50-year mining license by Mexico (extendable for another 50 years at ExO’s option) for the deposit that lies 25-40 km offshore in Baja California Sur.

We spent more than three years preparing an environmentally sustainable development plan with the assistance of experts in marine dredging and leading environmental scientists from around the world. Key features of the environmental plan included:

•

No chemicals would be used in the dredging process or released into the sea.

•

A specialized return down pipe that exceeds international best practices to manage the return of dredged sands close to the seabed, limiting plume or impact to the water column and marine ecosystem (including primary production).

•

The seabed would be restored after dredging in such a way as to promote rapid regeneration of seabed organisms in dredged areas.

•

Ecotoxicology tests demonstrated that the dredging and return of sediment to the seabed would not have toxic effects on organisms.

•

Sound propagation studies concluded that noise levels generated during dredging would be similar to whale-watching vessels, merchant ships and commercial fishing ships that already regularly transit this area, proving the system is not a threat to marine mammals.

•

Dredging limited to less than one square kilometer each year, which means the project would operate in only a tiny proportion of the concession area each year.

•

Proven turtle protection measures were incorporated, even though the deposit and the dredging activity are much deeper and colder than where turtles feed and live, making material harm to the species highly remote.

•

There will be no material impact on local fisheries as fishermen have historically avoided the water column directly above the deposit due to the naturally low occurrence of fish there.

•

The project would not be visible from the shoreline and would not impact tourism or coastal activities.

•

Precautionary mitigation measures were incorporated into the development plan in line with best-practice global operational standards.

•

The technology proposed to recover the phosphate sands has been safely used in Mexican waters for over 20 years on more than 200 projects.

Notwithstanding the factors stated above, in April 2016 the Mexican Ministry of the Environment and Natural Resources (“SEMARNAT”) unlawfully rejected the permit to move forward with the project.

ExO challenged the decision in Mexican federal court and in March 2018, the Tribunal Federal de Justicia Administrativa (“TFJA”), an 11-judge panel, ruled unanimously that SEMARNAT denied the application in violation of Mexican law and ordered the agency to re-take its decision. Just prior to the change in the Mexican administration later in 2018, SEMARNAT denied the permit a second time in defiance of the court. ExO challenged the decision again before the TFJA. On October 25, 2024, the TFJA announced its ruling in favor of SEMARNAT. ExO expects to appeal the TFJA’s ruling, and the appeal is pending.

In April 2019, we filed a claim under the North American Free Trade Agreement (“NAFTA”) arbitration claim against Mexico on behalf of Odyssey and ExO to protect our stockholders’ interests and significant investment in the project. Our claim sought compensation on the basis that SEMARNAT’s wrongful repeated denial of authorization has destroyed the value of our investment in violation of NAFTA.

On June 14, 2019, Odyssey and ExO executed an agreement that provided up to $6.5 million in funding for prior, current and future costs of the NAFTA action. On January 31, 2020, this agreement was amended and restated, as a result of which the availability increased to $10.0 million. In December 2020, Odyssey announced it secured an additional $10.0 million from the funder to aid in our NAFTA case. On June 14, 2021, the funder agreed to fund up to an additional $5.0 million for arbitration costs. The funder will not have any right of recourse against us unless the environmental permit is awarded or if proceeds are received (See Note 9, Derivative Financial Instruments – Litigation Financing).

On September 17, 2024, the Company received notification from the International Centre for Settlement of Investment Disputes (“ICSID”) of the arbitral award (the “Arbitral Award”) on the claims brought by the Company on behalf of itself and ExO, against the United Mexican States under NAFTA. The arbitral tribunal issued an award in favor of the Company and ExO. The award orders Mexico to pay $37.1 million for breaching its obligations under NAFTA, plus interest (the “Award Interest”) at the one-year Mexico Treasury bond rate, compounded annually, from October 12, 2018, until the award is paid in full, plus the arbitrators’ fees and ICSID administrative costs. The amounts awarded are net of Mexican taxes, and Mexico may not tax the award. The case filings and the award are available on the ICSID website. On December 12, 2024, Mexico commenced an application before the Ontario Superior Court of Justice seeking to set-aside the Arbitral Award.

In October 2024, the Company discovered that the Mexican mining authority unlawfully cancelled ExO’s mining concessions in June and August 2024. ExO is challenging the cancellation.

Joint Venture with Capital Latinoamericano

On December 23, 2024, the Company and Capital Latinoamericano, S.A. de C.V. (“CapLat”) entered into a Joint Venture Agreement (the “JV Agreement”) pursuant to which Odyssey and CapLat formed a joint venture to develop a strategic fertilizer production project in Mexico (the “JV Project”) building on the work completed by the Company to validate a high-quality subsea phosphate resource within Mexico’s Exclusive Economic Zone (“EEZ”). Pursuant to the JV Agreement, the Company and CapLat will work together to develop the JV Project and, subject to satisfaction of certain conditions, including certain regulatory approvals from Mexican governmental authorities, subsidiaries of each party will invest as equal partners, subject to adjustment based on final contributions, in a newly formed joint venture entity that will own and continue to develop and operate the JV Project. The JV Agreement

20

Table of Contents

also provides that the Company and CapLat have exclusive rights to develop the JV Project, and that CapLat has the exclusive right to develop with the Company any projects in the EEZ owned or developed by the Company during the next five years.

Each of the parties has the right to terminate the JV Agreement if the investment into the joint venture entity does not occur on or prior to December 31, 2026, or if there is a change of control of either party. In the event of a termination based on a change of control, the non-terminating party would be entitled to a termination fee of $10 million. The JV Agreement also sets forth representations and warranties, covenants, conditions, termination provisions, and other provisions customary for comparable transactions.

CIC Project:

CIC Limited (“CIC”) is a deep-sea mineral exploration company. CIC is supported by a consortium of companies providing expertise and financial contributions in support of development of the project. Odyssey is a member of the consortium, which also includes Royal Boskalis Westminster.

In February 2022, the Cook Islands Seabed Minerals Authority (“SBMA”) awarded CIC a five-year exploration license beginning June 2022. Offshore explorations and research commenced in the third quarter of 2022 with positive results in early sampling and testing of vessels and equipment, which informed requirements for viable operational functions as the basis for a longer-term operation over the license period. The early operations also resulted in preliminary resource sampling, which will ultimately accrue to the resource evaluation and regional environmental assessment.

Through a wholly owned subsidiary, we have earned and now hold approximately 14.2% of the current outstanding equity units of CIC issued in exchange for provision of services by the Company.

We have the ability to earn up to an aggregate of 20.0 million equity units through July 2025. This means we can earn approximately 1.0 million additional equity units in CIC under our current services agreement. We achieved our current equity position through the provision of services rendered to CIC (see Note 5, Investment in Unconsolidated Entities).

Ocean Minerals, LLC Project:

Ocean Minerals, LLC (“OML”) is a deepwater critical minerals exploration and development company incorporated in the Cayman Islands. Moana Minerals Limited (“Moana Minerals”) is a wholly owned subsidiary of OML and is a deepwater critical metals exploration and development company incorporated in the Cook Islands with offices and operations based in Rarotonga, Cook Islands. In February 2022, the SBMA awarded Moana Minerals a five-year exploration license (“EL3”) for a 23,630 square kilometer area in the Cook Islands’ EEZ.

Moana Minerals has validated vast polymetallic nodule resources in its exploration license area and, pursuant to the SBMA’s standards and guidelines, it is conducting further exploration activities to increase confidence in the reported mineral resource and size of the reported mineral resources and to secure environmental approvals to perform commercial operations. OML and its project partners are also advancing work to develop recovery systems to harvest these high-quality seafloor polymetallic nodules and processing solutions to convert them into commercial grade metals.

On June 4, 2023, Odyssey entered into a purchase agreement to acquire an approximately 13% interest in OML in exchange for a contribution by Odyssey of its interest in its then wholly owned subsidiary, ORI, whose sole asset was a 6,000-meter remotely operated vehicle (“ROV”), cash contributions of up to $10.0 million in a series of transactions over the following year, a Contribution Agreement and an Equity Exchange Agreement. On July 3, 2023, the parties consummated the initial closing of the purchase agreement, pursuant to which Odyssey’s wholly owned subsidiary obtained approximately 6.28% of OML’s outstanding equity interests. On October 18, 2024, Odyssey and OML entered into a Termination Agreement pursuant to which the parties terminated the OML Purchase Agreement. The Termination Agreement terminated the parties’ rights and obligations relating to the Second OML Units, Third OML Units and Optional Units (see Note 5, Investment in Unconsolidated Entities), but did not affect Odyssey’s ownership of the Initial OML Units or its obligation to pay the lease payments for the ROV (see Note 5, Investment in Unconsolidated Entities). The Termination Agreement also did not affect the Equity Exchange Agreement or Contribution Agreement (each as defined above), each of which remains in effect.

The 6,000-meter rated ROV contributed to OML by Odyssey provides OML with an additional tool to advance the project toward eventual applications for an environmental permit and harvesting license when exploration and feasibility studies are completed and demonstrate how harvesting can be done without serious environmental harm. OML continues to advance current Joint Ore Reserve Committee (“JORC”) compliant report, substantially increasing resources reporting to indicated and measured confidence levels and completing its preliminary Feasibility Study, among other important project milestones it is working to achieve.

LIHIR Gold Project:

The exploration license for the Lihir Gold Project covers a subsea area that contains several prospective gold exploration targets in two different mineralization types: seamount-related epithermal and modern placer gold. Two subaqueous debris fields within the

21

Table of Contents

area are adjacent to the terrestrial Ladolam Gold Mine and are believed to have originated from the same volcanogenic source. The resource lies 500-2,000 meters deep in the Papua New Guinea Exclusive Economic Zone off the coast of Lihir Island, adjacent to the location of one of the world’s largest known terrestrial gold deposits. We have an 85.6% interest in Bismarck Mining Corporation, Ltd, the Papua New Guinea company that holds the exploration license (the “Bismarck Exploration License”) for the project.

Previous exploration expeditions in the license area, including research conducted by Odyssey, indicate it is highly prospective for commercially viable gold content.

In 2021 and again in 2023, Papua New Guinea issued permit extensions allowing Odyssey to continue with our exploration program. We have developed an exploration program for the Lihir Gold Project to validate and quantify the precious and base metal content of the prospective resource. The Company has met with local regulatory authorities, specialists in local mining, environmental legal experts, and logistics support service companies in Papua New Guinea to establish baseline business functions essential for a successful program to support upcoming marine exploration operations in the license area. This offshore work began in late 2021 and is ongoing. Bismarck and Odyssey value the environment and respect the interests and people of Papua New Guinea and Lihir and are committed to transparent sharing of all environmental data collected during the exploration program.

Offshore survey and mapping operations commenced in December 2021 in the Papua New Guinea, Lihir license area and was completed in 2022. This work produced a high-resolution acoustic terrain model of the seafloor in the area, as well as acquiring acoustic images of subseafloor sediments and lithology. This allowed characterization of the geologic setting of the area and essentially created a "snapshot" of the environment. These activities will help us to further characterize the value of this project and allow informed decision making on how to proceed with environmentally sensitive direct geologic sampling. In the first half of 2023, a comprehensive project plan was designed identifying specific target areas for geological and environmental samples to be collected in future offshore operations. No timetable has been set for operations to commence, as operational plans are currently being developed. On November 13, 2023, Bismarck received a sixth term renewal for the Bismarck Exploration License.

During 2023, Odyssey continued exploration in the exploration license area to continue to validate the geological prospectivity of the property. In addition to examining the regional geological and tectonic settings of the region, additional multibeam data and 127 geological samples were collected, and seven ROV dives were conducted. These activities increased Bismarck’s confidence in the presence of enriched mineral targets within the exploration license area. Likewise, two target sites were identified for future resource sampling. Future exploration will focus on continued sampling in these locations while working towards a defined resource assessment and gathering environmental baseline data to compile an environmental impact assessment.

Odyssey's multi-year exploration program is planned to focus on robust environmental surveys and studies that will accrue to environmental permitting in compliance with PNG's requirements as well as the development of an Environmental Impact Assessment ("EIA"). During the exploration phase, steps to validate and quantify the precious and base metal content of the prospective resource would also be carried out. Once completed, if the data shows extraction can be carried out responsibly, Odyssey will apply for a mining license.

Further development of this project is dependent on the characterization resources during the exploration phase.

Going Concern Consideration

We have experienced several years of net losses and may continue to do so. Our ability to generate net income or positive cash flows for the next twelve months is dependent upon financings, our success in developing and monetizing our interests in mineral exploration entities, and generating income from exploration charters.

Our 2025 business plan requires us to generate new cash inflows to effectively allow us to perform our planned projects. We continually plan to generate new cash inflows through the monetization of our equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow ever becomes insufficient to meet our projected business plan requirements, we would be required to follow a contingency business plan based on curtailed expenses and fewer cash requirements.

In December 2024, we amended the March 2023 Notes (as defined below) and the December 2023 Notes (as defined below) to, among other items, extend the maturity date of our obligations, and add a conversion feature, thereby deferring a material cash need. In addition, on December 23, 2024, we entered into a Securities Purchase Agreement (the “SPA”) pursuant to which the Company issued and sold an aggregate of 7,377,912 shares of common stock to certain accredited investors at a purchase price of $0.55 per share. The aggregate purchase price for the shares, before deduction of the Company’s expenses associated with the transaction, was approximately $4.1 million. The proceeds of that sale of common stock, together with other anticipated cash inflows, is expected to provide sufficient operating funds into the second quarter of 2025. The SPA further provides the investors with the right, but not the obligation, to purchase an additional 7,220,141 shares of common stock at a purchase price of $1.10 per share at a subsequent closing to be held on April 30, 2025. That subsequent sale of common stock, if exercised by the investors under the SPA, is expected to provide sufficient operating funds through at least the fourth quarter of 2025.

Table of Contents

Our consolidated non-restricted cash balance at December 31, 2024 was $4.8 million. We had a working capital deficit at December 31, 2024 of $16.7 million. The total consolidated book value of our assets was approximately $18.5 million at December 31, 2024, which includes cash of $4.8 million. The fair market value of these assets may differ from their net carrying book value. The factors noted above raise doubt about our ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern.

Results of Operations

The dollar values discussed in the following tables, except as otherwise indicated, are approximations to the nearest thousands and therefore do not necessarily sum in columns or rows. For more detail refer to the Financial Statements and Supplementary Data in Item 8.

Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023

Year ended December 31, Change

Increase/(Decrease) (in thousands) 2024 2023 $ %

Net loss attributable to non-controlling interest 9,411 9,230 $ 181 2.0 %

Revenue

The revenue generated in each period was a result of performing marine research and project administration for our customers and related parties. Total revenue for the twelve months ended December 31, 2024 was $0.8 million, a decrease of $35,122 compared to $0.8 million from the twelve months ended December 31, 2023. We do not consider the fluctuation period over period to be significant.

One company to which we provided these services in both periods is a deep-sea mineral exploration company, CIC, which we consider to be a related party because our lead director is an indirect minority equity holder of CIC (see Note 14, Related Party Transactions). In addition, during the twelve months ended December 31, 2024, we provided services to OML, which is also a related party as we account for our interest in OML under the equity method of accounting.

Operating Expenses

Marketing, general and administrative expenses for the twelve months ended December 31, 2024 were $9.7 million, an increase of $2.8 million as compared to the twelve months ended December 31, 2023. The increase primarily resulted from an increase of $1.5 million in share-based compensation and employee bonuses and $1.7 million in audit and legal fees. These increases were offset in part by $0.4 million of employee compensation, and other general expenses.

Operations and research expenses are primarily focused around deep-sea mineral exploration, which includes minerals research, scientific services, marine operations and project management. Operations and research expenses decreased by $1.2 million during the twelve months ended December 31, 2024, as compared to the twelve months ended December 31, 2023, primarily as a result of decreases of $1.1 million in licenses and permits, $0.2 million of contract labor expense associated with ROV sea trials and a $0.1 million reduction in port fees, customs duties, and dockage. These decreases were offset in part by an increase of $0.2 million in professional services related to NAFTA arbitration.

Table of Contents

Total Other Income and Expense

Total other income/(expense) was $18.3 million and $6.5 million for the twelve months ended December 31, 2024 and 2023, respectively, resulting in an increase of $11.8 million.

The increase in income was attributable to:

•

a $27.2 million increase in the change in derivative fair value, mainly consisting of changes in fair value increases of (i) $20.0 million in warrants, (ii) $6.7 million in OML Put Option, (iii) $1.9 million in litigation financing, and (iv) $0.8 million of 37N Note, which are offset in part by decreases of (y) $2.1 million in March 2023 Notes and (z) $0.1 million in December 2023 Notes;

•

$9.8 million received in connection with residual economic interest in the shipwreck received during 2024, which did not occur in 2023; and

•

a $2.8 million increase in foreign exchange gain.

The above increases in income were offset by increases in expense attributable to:

•

$21.9 million primarily related to a gain on debt extinguishment predominantly from the termination of the MINOSA debt in 2023;

•

$4.2 million of a loss on the OML termination agreement in 2024;

•

a $1.5 million increase in interest expense primarily related to March 2023 Notes and December 2023 Notes, which includes $0.7 million of the write-off of the debt discount related to the debt extinguishment of the March 2023 Notes and December 2023 Notes;

•

a $0.2 million decrease in interest income;

•

a $0.2 million decrease in the gain on sale of wholly owned entity, due to the recognized sale of ORI in 2023, that did not recur in 2024.

Taxes

Due to losses and our net operating loss carryforwards, we did not accrue any taxes in either period ending 2024 or 2023.

Non-Controlling Interest

Commencing in 2013, we became the controlling stockholder of Oceanica. Our financial statements therefore include the financial results of Oceanica and its subsidiary, ExO. Except for intercompany transactions that are fully eliminated upon consolidation, Oceanica's revenues and expenses, in their entirety, are shown in our consolidated financial statements. The share of Oceanica's net losses corresponding to the equity of Oceanica not owned by us is subsequently shown as the "Non-Controlling Interest" in our consolidated statements of operations. The non-controlling interest adjustment in the year ended December 31, 2024 was $9.4 million as compared to $9.2 million for the twelve months ended December 31, 2023. The increase in these amounts is primarily due to the increase in permit fees and other standard operating costs.

Discussion of Cash Flows

Operating Activities

Net cash provided by operating activities for the year ended December 31, 2024 was $0.6 million. This represents an approximate $10.8 million increase in cash provided when compared to the use of $10.2 million for the year ended December 31, 2023. Cash flows used in operating activities for the year ended December 31, 2024 reflected a net income before non-controlling interest of $6.2 million and is adjusted primarily by non-cash items of $3.7 million, and includes other income of $9.8 million from a residual economic interest in a salvaged shipwreck. Cash used in operating activities is adjusted primarily by non-cash items of $3.7 million, including: (i) $18.9 million in changes in fair value of derivative liabilities, relating primarily to the change in fair value of warrants, OML Put Option, and Litigation financing liability, (ii) $4.2 million of a loss on Termination Agreement, (iii) amortization of deferred discount $3.3 million, (iv) note payable accretion of $2.3 million, (v) share-based compensation of $2.0 million, and (vi) $1.8 million of PIK interest. Other operating activities resulted in an increase in working capital of $1.9 million. This $1.9 million increase includes a $0.4 million decrease to accounts payable, $2.1 million increase to accrued expenses partially offset by a $0.2 million increase in other working capital accounts.

Cash flows used in operating activities for the year ended December 31, 2023, of $10.2 million reflected a net loss before non-controlling interests of $3.9 million and is adjusted primarily by non-cash items of $7.6 million, which primarily includes a gain on debt extinguishment of $21.2 million, services provided to unconsolidated entities of $0.8 million, and note receivable interest accretion of $0.3 million, which were partially offset primarily by a change in derivatives liabilities fair value of $8.3 million, debt accretion and amortization of fees and discounts of $3.7 million, interest paid in kind of $0.9 million, share-based compensation of $0.6 million, amortization of financing liabilities of $0.4 million, and depreciation of $0.2 million. Other operating activities resulted in a decrease in working capital of $1.3 million. This $1.3 million increase primarily comprises a $2.6 million increase to accrued expenses, and a decrease in accounts payable of $1.7 million offset by an increase of approximately $0.4 million in other working capital accounts. The increase in accrued expenses and accounts payable is predominantly related to increased accrued interest and permit fees.

Investing Activities

Cash flows used in investing activities for the twelve months ended December 31, 2024, was $84,350. This represents an approximate $0.9 million decrease from cash flows used in investing activities of $1.0 million for the twelve months ended December 31, 2023. During the twelve months ended December 31, 2024, the net cash used in investing activities was solely for the purchase of property and equipment.

During the year ended December 31, 2023, the primary items affecting the net cash used in investing activities were $1.3 million for the purchase of property and equipment, cash paid for the investment in a new unconsolidated entity of $1.0 million, offset by proceeds from related party of $1.0 million and proceeds from the sale of equipment of $0.3 million.

Financing Activities

Cash flows provided by financing activities for the twelve months ended December 31, 2024, was $0.2 million. The $0.2 million primarily consisted of $3.9 million from proceeds from the issuance of common stock, partially offset by $3.0 million of debt obligation payments, $0.5 million of sale leaseback payments and $0.1 million of offering costs paid on financing.

Cash flows provided by financing activities for the twelve months ended December 31, 2023, were $13.8 million. The $13.8 million consisted of $21.4 million received from the issuance of loans payable, proceeds from warrants exercised of $0.3 million, $0.2

Other Cash Flow and Equity Areas

General Discussion

At December 31, 2024, we had cash of $4.8 million, an increase of $0.8 million from the December 31, 2023 balance of $4.0 million. Financial debt of the company was $22.9 million and $23.3 million at December 31, 2024 and 2023, respectively.

Financings

Stock Purchase Agreement

On December 23, 2024, we entered into a Securities Purchase Agreement (the “SPA”) pursuant to which the Company issued and sold an aggregate of 7,377,912 shares of common stock to certain accredited investors at a purchase price of $0.55 per share. The aggregate purchase price for the shares, before deduction of the Company’s expenses associated with the transaction, was approximately $4.1 million. The SPA further provides the investors with the right, but not the obligation, to purchase an additional 7,220,141 shares of common stock at a purchase price of $1.10 per share at a subsequent closing to be held on April 30, 2025.

The Company analyzed the SPA, specifically with respect to the shares issued and the right to purchase additional shares at a later date within the guidance of ASC 480, Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging, and determined the right to purchase additional shares is a written call option that qualifies as a free standing instrument based on the definition of the second criterion in the GAAP definition of a freestanding financial instrument that the instruments are legally detachable and separately exercisable. The Company determined the written call option does not require liability classification under Topic 480 and does not meet the definition of a derivative, as there is no net settlement provision. Lastly, the Company concluded the written call option should be classified as an equity instrument, as it meets the criteria for equity classification of a non-derivative instrument under ASC 815-40.

On December 23, 2024, the Company recorded the written call option as well as a capital contribution from its investors within APIC at a fair value of approximately $1.5 million. The written call option does not require subsequent remeasurement each reporting period. The capital contribution was recorded for the excess of proceeds received compared to the fair value of common stock and written call option.

Debt Financing

The Company’s consolidated loans payable consisted of the following carrying values at:

March 2023 Notes and Warrant Purchase Agreement

On March 6, 2023, Odyssey entered into a Note and Warrant Purchase Agreement (the “March 2023 Note Purchase Agreement”) with an institutional investor pursuant to which Odyssey issued and sold to the investor (a) a promissory note (the “March 2023 Note”)

26

Table of Contents

in the principal amount of up to $14.0 million and (b) a warrant (the “March 2023 Warrants” and, together with the March 2023 Note, the “March 2023 Securities”) to purchase shares of our Common Stock.

The total proceeds of $14.0 million were allocated between debt and equity for the warrants based on the relative fair value of the two instruments. As a result, there was a debt discount of $3.7 million, which is amortized over the remaining term of the March 2023 Note Purchase Agreement using the effective interest method, which is charged to interest expense. In connection with the December 2024 amendment discussed below, any unamortized debt discount was written off to interest expense.

The principal amount outstanding under the March 2023 Note bears interest at the rate of 11.0% per annum, and interest is payable in cash on a quarterly basis, except that, (a) at Odyssey’s option and upon notice to the holder of the March 2023 Note, any quarterly interest payment may be satisfied, in lieu of paying such cash interest, by adding an equivalent amount to the principal amount of the March 2023 Note (“PIK Interest”), and (b) the first quarterly interest payment due under the March 2023 Note will be satisfied with PIK Interest. The March 2023 Note provides Odyssey with the right, but not the obligation, upon notice to the holder of the March 2023 Note to redeem (x) at any time before the first anniversary of the issuance of the March 2023 Note, all or any portion of the indebtedness outstanding under the March 2023 Note (together with all accrued and unpaid interest, including PIK Interest) for an amount equal to one hundred twenty percent (120%) of the outstanding principal amount so being redeemed, and (y) at any time on or after the first anniversary of the issuance of the March 2023 Note, all or any portion of the indebtedness outstanding under the March 2023 Note (together with all accrued and unpaid interest, including PIK Interest). Unless the March 2023 Note is sooner redeemed at Odyssey’s option, all indebtedness under the March 2023 Note was due and payable on September 6, 2024. Under the terms of the March 2023 Note Purchase Agreement, Odyssey agreed to use the proceeds of the sale of the Securities to fund Odyssey’s obligations under the Termination Agreement (as defined above), to pay legal fees and costs related to Odyssey’s NAFTA arbitration against the United Mexican States, to pay fees and expenses related to the transactions contemplated by the March 2023 Note Purchase Agreement, and for working capital and other general corporate expenditures. Odyssey’s obligations under Note are secured by a security interest in substantially all of Odyssey’s assets (subject to limited stated exclusions).

Under the terms of the March 2023 Warrant, the holder had the right for a period of three years after issuance to purchase up to 3,703,703 shares of Odyssey’s common stock at an exercise price of $3.78 per share, which represents 120.0% of the official closing price of Odyssey’s common stock on the Nasdaq Capital Market immediately preceding the signing of the March 2023 Note Purchase Agreement, upon delivery of a notice of exercise to Odyssey. Upon exercise of the March 2023 Warrant, Odyssey has the option to either (a) deliver the shares of common stock issuable upon exercise or (b) pay to the holder an amount equal to the difference between (i) the aggregate exercise price payable under the notice of exercise and (ii) the product of (A) the number of shares of common stock indicated in the notice of exercise multiplied by (B) the arithmetic average of the daily volume-weighted average price of the common stock on the Nasdaq Capital Market for the five consecutive trading days ending on, and including, the trading day immediately prior to the date of the notice of exercise. The warrant provides for customary adjustments to the exercise price and the number of shares of common stock issuable upon exercise in the event of a stock split, recapitalization, reclassification, combination or exchange of shares, separation, reorganization, liquidation, or the like.

On March 6, 2023, the Company recognized the fair value of the March 2023 Warrant using the Black-Scholes valuation technique at $3.7 million and classified the warrants as equity and debt discount of the March 2023 Note.

In connection with the execution and delivery of the March 2023 Note Purchase Agreement, Odyssey entered into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which Odyssey registered the offer and sale of the shares (the “Exercise Shares”) of Odyssey common stock issuable upon exercise of the Warrant in a Prospectus filed with the SEC and declared effective as of June 1, 2023.

We incurred $98,504 in related fees which are being amortized over the term of the March 2023 Note Purchase Agreement and charged to interest expense.

For the years ended December 31, 2024 and 2023, we recorded $1.8 million and $2.0 million of interest expense from the amortization of the debt discount, respectively, and $44,934 and $53,810 interest from the fee amortization which has been recorded in interest expense, respectively. The carrying value of the debt was $10.5 million and $13.1 million as of December 31, 2024 and 2023, respectively, which includes of interest Paid In Kind (“PIK”) of $1.2 million and $0.8 million, respectively, and was net of unamortized debt fees of $89,820 and $44,693, net of unamortized debt discount of $1.5 million and $1.7 million, respectively, associated with the fair value of the warrant. The total face value of this obligation at December 31, 2024 and 2023 was $13.1 million and $14.9 million, respectively.

December 2024 Amendment

On December 20, 2024, the Company and the holders of the March 2023 Securities entered into an Amendment to Note and Warrant March Purchase Agreement (the “March 2023 NWPA Amendment”) pursuant to which the March 2023 Purchase Agreement was amended to, among other things, (a) add certain covenants, including a requirement for the Company to maintain a minimum liquidity level, and modify certain existing covenants, (b) add related events of default, and (c) provide that the Company’s obligations

under the March 2023 Purchase Agreement, the March 2023 Notes, and related documents are guaranteed by specified subsidiaries of the Company.

In connection with the March 2023 NWPA Amendment, the Company issued to each of the holders of the March 2023 Securities an Amended and Restated Convertible Promissory Note (the “March 2023 AR Notes”), and the Company and such holders entered into amendments (the “March 2023 Warrant Amendments”) to the March 2023 Warrants. The March 2023 Notes were modified by the March 2023 AR Notes to, among other things, (a) extend the maturity date to June 30, 2025, and, subject to an amendment of the Company’s December 2023 Notes (as defined below), to December 31, 2025, (b) add a conversion feature pursuant to which the holders have the right to convert the indebtedness under the March 2023 AR Notes into shares of the Company’s common stock at a conversion rate equal to 75% of the 30-day volume weighted average price of the Company’s common stock, provided that the conversion rate will not be less than $1.10 or greater than $2.20. The March 2023 AR Notes include limitations on the holders’ right to exercise the conversion feature, including customary limitations intended to ensure compliance with the rules of the Nasdaq Capital Market and a provision that provides the Company with the right to settle any exercise of the conversion feature in cash rather than by issuing shares of common stock. The condition relating to amendment of the December 2023 Notes also was satisfied on December 20, 2024, such that the maturity date of the March 2023 AR Notes is currently December 31, 2025.

The March 2023 Warrant Amendments modify the exercise price of the March 2023 Warrants from $3.78 to $1.10. In connection with the March 2023 NWPA Amendment, the Company also granted (a) registration rights to the holders of the March 2023 AR Notes and the March 2023 Warrants with respect to the shares of common stock issuable upon conversion or exercise thereof and (b) provided the holders with security interests in additional collateral to secure the Company’s obligations to the holders. The Company and the investors also entered into a Registration Rights Agreement (the “March 2023 Rights Agreement”) pursuant to which the Company agreed to prepare and file a registration statement with the SEC relating to the offer and sale of the shares of common stock on or before February 28, 2025. The investors also have certain “piggyback” registration rights under the March 2023 Rights Agreement.

The March 2023 NWPA Amendment, the March 2023 AR Notes, the March 2023 Warrant Amendments, and the March 2023 Rights Agreement also include representations and warranties, covenants, conditions, and other provisions customary for comparable transactions.

The Company evaluated the March 2023 NWPA Amendment under ASC 470 and concluded it should be recorded as a debt extinguishment as it added a substantive conversion option. In addition, based on the criteria of ASC 480 and ASC 815-15-25-1, the March 2023 AR Notes are classified as a liability on the consolidated balance sheet with a conversion option that is recorded as an embedded derivative. As a result, the conversion option was recorded as discount on the debt and adjusted to fair value at each reporting period outstanding with changes recognized through Change in derivative liabilities fair value on the consolidated statement of operations. At December 31, 2024, the debt instrument and embedded derivatives were recorded on the consolidated balance sheets as $13.1 million, in Loans payable – short term, and $2.7 million, in debt derivative, respectively.

December 2023 Note and Warrant Purchase Agreement

On December 1, 2023, we entered into a Note and Warrant Purchase Agreement (the “December 2023 Note Purchase Agreement”) with institutional investors pursuant to which we issued and sold to the investors (a) a series of promissory notes (the “December 2023 Notes”) in the principal amount of up to $6.0 million and (b) two tranches of warrants (the “December 2023 Warrants” and, together with the December 2023 Notes, the “December 2023 Securities”) to purchase shares of our common stock. We issued December 2023 Notes in the aggregate amount of $3.75 million and related warrants on December 1, 2023, and December 2023 Notes in the aggregate amount of $2.25 million and related warrants on December 28, 2023.

The total proceeds of $6.0 million were allocated between debt and warrant liability by recognizing the warrants at their full fair value and allocating the residual proceeds to the December 2023 Notes. The initial fair value of the December 2023 Warrants (as defined below) was $2.4 million, resulting in a corresponding discount on the December 2023 Notes which is being amortized over the remaining term of the December 2023 Note Purchase Agreement using the effective interest method, which is charged to interest expense.

The principal amount outstanding under the December 2023 Notes bears interest at the rate of 11.0% per annum, and interest is payable in cash on a quarterly basis, except that, (a) at our option and upon notice to the holder of the December 2023 Notes, any quarterly interest payment may be satisfied, in lieu of paying such cash interest, by adding an equivalent amount to the principal amount of the December 2023 Notes (“December 2023 PIK Interest”), and (b) the first quarterly interest payment due under the December 2023 Notes will be satisfied with December 2023 PIK Interest. The December 2023 Notes provide us with the right, but not the obligation, upon notice to the holders of the December 2023 Notes to redeem (x) at any time before the first anniversary of the issuance of the December 2023 Notes, all or any portion of the indebtedness outstanding under the December 2023 Notes (together with all accrued and unpaid interest, including December 2023 PIK Interest) for an amount equal to one hundred twenty percent (120%) of the outstanding principal amount so being redeemed, and (y) at any time on or after the first anniversary of the issuance of the December 2023 Notes, all or any portion of the indebtedness outstanding under the December 2023 Notes (together with all accrued and unpaid interest, including December 2023 PIK Interest). Unless the December 2023 Notes are sooner redeemed at our option, all indebtedness under the December 2023 Notes was due and payable on June 1, 2025. Under the terms of the December 2023 Note Purchase Agreement,

28

Table of Contents

we agreed to use the proceeds of the sale of the December 2023 Securities for working capital and other general corporate expenditures and to pay fees and expenses related to the transactions contemplated by the December 2023 Note Purchase Agreement. Our obligations under December 2023 Notes are secured by a pledge of and security interest in our equity interests in Odyssey Marine Cayman Limited (subject to limited stated exclusions).

Under the terms of the first tranche of December 2023 Warrants, the holders had the right for a period of three years after issuance to purchase an aggregate of up to 1,411,765 shares of our common stock at an exercise price of $4.25 per share, which represents 120.0% of the official closing price of our common stock on the Nasdaq Capital Market immediately preceding the signing of the December 2023 Note Purchase Agreement, upon delivery of a notice of exercise to Odyssey. Under the terms of the second tranche of December 2023 Warrants, the holders have the right for a period of three years after issuance to purchase an aggregate of up to 211,565 shares of our common stock at an exercise price of $7.09 per share, which represents 200.0% of the official closing price of our common stock on the Nasdaq Capital Market immediately preceding the signing of the December 2023 Note Purchase Agreement, upon delivery of a notice of exercise to Odyssey. Upon exercise of the December 2023 Warrants, Odyssey has the option to either (a) deliver the shares of common stock issuable upon exercise or (b) pay to the holder an amount equal to the difference between (i) the aggregate exercise price payable under the notice of exercise and (ii) the product of (A) the number of shares of common stock indicated in the notice of exercise multiplied by (B) the arithmetic average of the daily volume-weighted average price of the common stock on the Nasdaq Capital Market for the five consecutive trading days ending on, and including, the trading day immediately prior to the date of the notice of exercise. The December 2023 Warrants provide the holders with a cashless exercise option if we have announced payment of a dividend or distribution on account of our common stock. The December 2023 Warrants also include customary adjustments to the exercise price and the number of shares of common stock issuable upon exercise in the event of a stock split, recapitalization, reclassification, combination or exchange of shares, separation, reorganization, liquidation, or the like.

In connection with the execution and delivery of the December 2023 Note Purchase Agreement, we entered into a registration rights agreement (the “December 2023 Registration Rights Agreement”) pursuant to which we agreed to register the offer and sale of the shares (the “December 2023 Exercise Shares”) of our common stock issuable upon exercise of the December 2023 Warrants. Pursuant to the December 2023 Registration Rights Agreement, we agreed to prepare and file with the SEC a registration statement covering the resale of the December 2023 Exercise Shares and to use our reasonable best efforts to have the registration statement declared effective by the SEC as soon as practicable thereafter, subject to stated deadlines.

The Company determined that the December 2023 Warrants meet the definition of a derivative and are not considered indexed to the Company’s own stock due to the settlement adjustment that provides that the share price input upon cashless exercise is always based on the highest of three prices. As such, the December 2023 Warrants were recognized as derivative liabilities and will be initially and subsequently measured at fair value with the gain or loss due to changes in fair value recognized in the current period. The Company noted that when debt is issued with liability-classified stock purchase warrants, the residual method should be used so that the warrants are recognized at fair value at issuance and the residual proceeds are allocated to the debt.

We incurred $65,500 in related expenses, which are being amortized over the term of the December 2023 Note Purchase Agreement and charged to interest expense.

For the year ended December 31, 2024 and 2023, we recorded $2.3 million and $0.1 million of interest expense from the amortization of the debt discount, respectively, and $50,799 and $3,705 interest from the fee amortization, respectively. The carrying value of the debt was $5.8 million and $3.7 million as of December 31, 2024 and 2023, respectively, and was net of unamortized debt fees of $29,710 and $61,795, respectively, and net of unamortized debt discount of $0.5 million and $2.3 million, respectively, associated with the fair value of the warrant. The total face value of this obligation at December 31, 2024 and 2023 was $6.6 million and $6.0 million, respectively.

December 2024 Amendment

On December 20, 2024, the Company and the holders of the December 2023 Securities entered into an Amendment to Note and Warrant Purchase Agreement (the “December 2023 NWPA Amendment”) pursuant to which issued to each of the holders of the December 2023 Securities an Amended and Restated Convertible Promissory Note (the “December 2023 AR Notes”), and the Company and such holders entered into amendments (the “December 2023 Warrant Amendments”) to the December 2023 Warrants. The December 2023 Notes were modified by the December 2023 AR Notes to, among other things, (a) extend the maturity date to April 1, 2026, (b) add a conversion feature pursuant to which the holders have the right to convert the indebtedness under the December 2023 AR Notes into shares of the Company’s common stock at a conversion rate equal to 75% of the 30-day volume weighted average price of the Company’s common stock, provided that the conversion rate will not be less than $1.10. The December 2023 AR Notes include limitations on the holders’ right to exercise the conversion feature, including customary limitations intended to ensure compliance with

29

Table of Contents

the rules of the Nasdaq Capital Market and a provision that provides the Company with the right to settle any exercise of the conversion feature in cash rather than by issuing shares of common stock.

The December 2023 Warrant Amendments modify the exercise price of one tranche of the December 2023 Warrants from $4.25 to $1.23 and the exercise price of the other tranche of the December 2023 Warrants from $7.09 to $2.05. In connection with the December 2023 NWPA Amendment, the Company also granted registration rights to the holders of the December 2023 AR Notes and the December 2023 Warrants with respect to the shares of common stock issuable upon conversion or exercise thereof. The Company and the investors also entered into a Registration Rights Agreement (the “December 2023 Rights Agreement”) pursuant to which the Company agreed to prepare and file a registration statement with the SEC relating to the offer and sale of the shares of common stock on or before February 28, 2025. The investors also have certain “piggyback” registration rights under the December 2023 Rights Agreement.

The Company evaluated the December 2023 NWPA Amendment under ASC 470 and concluded it should be recorded as a debt extinguishment as it added a substantive conversion option. In addition, based on the criteria of ASC 480 and ASC 815-15-25-1, the December 2023 AR Notes are classified as a liability on the consolidated balance sheet with a conversion option that is recorded as an embedded derivative. As a result, the conversion option was recorded as discount on the debt and adjusted to fair value at each reporting period outstanding with changes recognized through Change in derivative liabilities fair value on the consolidated statement of operations. At December 31, 2024, the debt instrument and embedded derivatives were recorded on the consolidated balance sheets as $6.7 million, inclusive of $0.2 million of accrued interest, in Loans payable, and $0.3 million, in debt derivative, respectively.

37North

On June 29, 2023, we entered into a Note Purchase Agreement (“Note Agreement”) with 37North SPV 11, LLC (“37N”) pursuant to which 37N agreed to loan us $1.0 million. The proceeds from this transaction were received in full on June 29, 2023. Pursuant to the Note Agreement, the indebtedness was non-interest bearing and matured on July 30, 2023. At any time from 31 days after the maturity date, 37N has the option to convert all or a portion of the outstanding amount of the indebtedness into conversion shares equal to the quotient obtained by dividing (A) 120% of the amount of the indebtedness, by (B) the lower of $3.66 or 70% of the 10-day volume-weighted average principal (“VWAP”) market trading price of Common Stock. The aggregate maximum number of shares of Common Stock to be issued in connection with conversion of the indebtedness is not to exceed (i) 19.9% of the outstanding shares of Common Stock prior to the date of the Agreement, (ii) 19.9% of the combined voting power of the outstanding voting securities, or (iii) such number of shares of Common Stock that would violate the applicable listing rules of the Principal Market if the stockholders did not approve the issuance of Common Stock upon conversion of the indebtedness.

Any time prior to maturity, the Company had the option to prepay the indebtedness at an amount of 108% of the unpaid principal. From the maturity date to 29 days after the maturity date (August 27, 2023), we were permitted to repay all (but not less than) of an amount equal to 112.5% of the unpaid amount of the indebtedness. At any time after the 30th day after the maturity date (August 28, 2023), we are permitted to repay all (but not less than) of an amount equal to 115% of the unpaid amount of the indebtedness after 10 days’ notice. If 37N delivers an exercise notice during this 10-day period, the note issued pursuant to the Note Agreement (the “37N Note”) would be converted to shares of Common Stock, instead of being repaid.

If 37N delivers an exercise notice and the number of shares issuable is limited by the 19.9% limitation outlined above, then we are permitted to repay all the remaining unpaid amount of the Loan in an amount equal to 130% of the remaining unpaid amount.

We evaluated the indebtedness and, based on the criteria of ASC 480 Distinguishing Liabilities from Equity and 815 Derivatives and Hedging, the 37N convertible note is classified as a liability on the consolidated balance sheet with a share settled redemption feature that is recorded as an embedded derivative. As a result, the share settled redemption and conversion features were recorded at fair value at each reporting period outstanding with changes recognized through Interest expenses on the consolidated statement of operations. The Company analyzed the conversion feature of the note and determined that, because it includes a conditional obligation to issue a variable number of shares based on a fixed amount known at inception, the debt is properly classified as a liability in the balance sheet. The Company identified seven embedded features, all of which were of de minimis fair value other than the Share Settled Redemption Feature. As such, only that was bifurcated and accounted for separately from the debt host. Certain default put provisions were not considered to be clearly and closely related to the debt host, but management concluded that the value of these default put provisions was de minimis.

On December 27, 2023, 37N delivered an exercise notice to us pursuant to which it exercised its right to convert $0.3 million of the outstanding indebtedness under the Note Agreement into shares of our Common Stock. In accordance with the Note Agreement, based on the applicable conversion rate of $2.3226 under the agreement, we issued 155,000 shares of our Common Stock to 37N on December 29, 2023.

Throughout 2024, 37N delivered exercise notices as follows:

As a result of the above conversions, as of December 31, 2024, the debt instrument and embedded derivatives related to the Note Agreements were zero. At December 31, 2023, the debt instrument and embedded derivatives were recorded on the consolidated balance sheets at fair value of $0.8 million and $0.7 million, respectively, under Loans payable – short term and Derivative liabilities and other – long term.

Other Financing Arrangement

Litigation Financing

On June 14, 2019, Odyssey and Exploraciones Oceánicas S. de R.L. de C.V., our Mexican subsidiary ("ExO" and, together with Odyssey, the "Claimholder"), and Poplar Falls LLC (the "Funder") entered into an International Claims Enforcement Agreement (the "Agreement"), pursuant to which the Funder agreed to provide funding to the Claimholder to facilitate the prosecution and recovery of the claim by the Claimholder against the United Mexican States under Chapter Eleven of the North American Free Trade Agreement ("NAFTA") for violations of the Claimholder's rights under NAFTA related to the development of an undersea phosphate deposit off the coast of Baja Sur, Mexico (the "Project"), on our own behalf and on behalf of ExO and United Mexican States (the "Subject Claim"). Pursuant to the Agreement, the Funder agreed to specified fees and expenses regarding the Subject Claim (the "Claims Payments") incrementally and at the Funder's sole discretion.

Under the terms of the Agreement, the Funder agreed to make Claims Payments in an aggregate amount not to exceed $6.5 million (the "Maximum Investment Amount"). The Maximum Investment Amount will be made available to the Claimholder in two phases, as set forth below:

(a)

a first phase, in which the Funder shall make Claims Payments in an aggregate amount no greater than $1.5 million for the payment of antecedent and ongoing costs ("Phase I Investment Amount"); and

(b)

a second phase, in which the Funder shall make Claims Payments in an aggregate amount no greater than $5.0 million for the purposes of pursuing the Subject Claim to a final award ("Phase II Investment Amount").

Upon exhaustion of the Phase I Investment Amount, the Claimholder will have the option to request Tranche A of the Phase II Investment Amount, consisting of funding up to $3.5 million ("Tranche A Committed Amount"). Upon exhaustion of the Tranche A Committed Amount, the Claimholder will have the option to request Tranche B of the Phase II Investment Amount, consisting of funding of up to $1.5 million ("Tranche B Committed Amount"). The Claimholder must exercise its option to receive the Tranche A Committed Amount in writing, no less than thirty days before submitting a Funding Request to the Funder under Tranche A. The Claimholder must exercise its option to receive the Tranche B Committed Amount in writing within forty-five days after the exhaustion of the Tranche A Committed Amount. Pursuant to the Agreement, the Claimholder agreed that, upon exercising the Claimholder's option to receive funds under Phase I, Tranche A of Phase II, or Tranche B of Phase II, the Funder will be the sole source of third-party funding for the specified fees and expenses of the Subject Claim under each respective phase and tranche covered by the option exercised, and the Claimholder will obtain funding for such fees and expenses only as set forth in the Agreement. The Funder was due a closing fee of $80,000 for the Phase I Investment Amount, and $80,000 for the Phase II Investment Amount to pay third parties in connection with due diligence and other administrative and transaction costs incurred by the Funder prior to and in furtherance of execution of the Agreement.

Table of Contents

Upon the Funder making Claims Payments to the Claimholder or its designees in an aggregate amount equal to the Maximum Investment Amount, the Funder has the option to continue funding the specified fees and expenses in relation to the Subject Claim on the same terms and conditions provided in the Agreement. The Funder must exercise its option to continue funding in writing, within thirty days after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount. If the Funder exercises its option to continue funding, the parties agreed to attempt in good faith to amend the Agreement to provide the Funder with the right to provide at the Funder's discretion funding in excess of the Maximum Investment Amount, in an amount up to the greatest amount that may then be reasonably expected to be committed for investment in Subject Claim. If the Funder declines to exercise its option, the Claimholder may negotiate and enter into agreements with one or more third parties to provide funding, which shall be subordinate to the Funder's rights under the Agreement.

The Agreement provides that the Claimholder may at any time without the consent of the Funder either settle or refuse to settle the Subject Claim for any amount; provided, however, that if the Claimholder settles the Subject Claim without the Funder's consent, which consent shall not be unreasonably withheld, conditioned, or delayed, the value of the Recovery Percentage (as defined below) will be deemed to be the greater of (a) the Recovery Percentage (under Phase I or Phase II, as applicable), or (b) the total amount of all Claims Payments made in connection with such Subject Claim multiplied by three (3).

If the Claimholder ceases the Subject Claim for any reason other than (a) a full and final Arbitral Award against the Claimholder or (b) a full and final monetary settlement of the claims, including in particular, for a grant of an environmental permit to the Claimholder allowing it to proceed with the Project (with or without a monetary component), all Claims Payments under Phase I and, if Claimholder has exercised the corresponding option, the Tranche A Committed Amount and Tranche B Committed Amount, shall immediately convert to a senior secured liability of the Claimholder. This sum shall incur an annualized internal rate of return ("IRR") of 50.0% retroactive to the date each Funding Request was paid by the Funder (under Phase I), or, to the conversion date for the Tranche A Committed Amount and Tranche B Committed Amount of Phase II if the Claimholder has exercised the respective option (collectively, the "Conversion Amount"). Such Conversion Amount and any and all accrued IRR shall be payable in-full by the Claimholder within 24 months of the date of such conversion, after which time any outstanding Conversion Amounts, shall accrue an ("IRR") of 100.0%, retroactive to the conversion date (the "Penalty Interest Amount"). The Claimholder will execute such documents and take other actions as necessary to grant the Funder a senior security interest on and over all sums due and owing by the Claimholder in order to secure its obligation to pay the Conversion Amount to the Funder. If the Claimholder ceases the Subject Claim due to the grant of an environmental permit (with or without a monetary component), all Claims Payments under Phase 1 and, if the Claimholder has exercised the corresponding option, the Tranche A Committed Amount and Tranche B Committed Amount shall immediately convert to a senior secured liability of the Claimholder and shall incur an annualized an IRR of 50.0% on the Conversion Amount, noted above, from the conversion date. Management has estimated it is more likely than not the Subject Claim will result in the issuance of the environmental permit requiring us to record interest under Generally Accepted Accounting Principles in the United States ("US GAAP"). Reliance should not be placed on this estimate in determining the likely outcome of the Subject Claim.

If, at any time after exercising its option to receive funds under either Tranche A or Tranche B of Phase II, the Claimholder wishes to fund the Subject Claim with its own capital ("Self-Funding") (which excludes any Claims Payments made, either directly or indirectly, by any other third party), the Claimholder shall immediately pay to the Funder the Conversion Amount, provided that this requirement shall not apply if, after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount, the Funder does not exercise its option to provide Follow-On Funding.

In the event of any receipt of proceeds resulting from the Subject Claim (as defined in the Agreement, "Proceeds"), the Funder shall be entitled to any additional sums above the Conversion Amount to which the Funder is entitled as described below. Should the Claimholder cease the Subject Claim as described above after Self-Funding the Claim, accrued IRR and Penalty Interest shall be calculated and paid to the Funder as set forth above. The Funder's rights to the Recovery Percentage as defined below shall survive any decision by Claimholder to utilize Self-Funding. The parties acknowledged that the Agreement constitutes a sale of the right to a portion of the Proceeds (if any) arising from the Subject Claim as set forth in this Agreement. The Claimholder has relinquished its right to the portion of the proceeds, if any, that the Funder would have the right to as described below. This sale of proceeds is being accounted for under the guidance of ASC 815 Derivatives and Hedging)

On each Distribution Date, distributions of the Proceeds shall be made to the Claimholder and the Funder in accordance with subparagraph (a) or (b) below (the "Recovery Percentage"), as applicable:

(a)

If the Claimholder receives only the Phase I Investment Amount from the Funder, the first Proceeds shall be distributed as follows:

(i)

first, 100.0% to the Funder, until the cumulative amount distributed to the Funder equals the total Claims Payments paid by the Funder under Phase I;

(ii)

second, 100.0% to the Funder until the cumulative amount distributed to the Funder equals an IRR of 20% of Claims Payments paid by the Funder under Phase I ("Phase I Compensation"), per annum; and

32

Table of Contents

(iii)

thereafter, 100.0% to the Claimholder.

(b)

If the Claimholder exercises its options to receive Tranche A or both Tranche A and Tranche B of the Phase II Investment Amount, the first Proceeds shall be distributed as follows:

(i)

first, 100.0% to the Funder until the cumulative amount distributed to the Funder equals the total Claims Payments paid by the Funder under Phases I and II;

(ii)

second, 100.0% to the Funder until the cumulative amount distributed to the Funder equals an additional 300.0% of Phase I Investment Amount; plus an additional 300% of the Tranche A Committed Amount (i.e. 300.0% of $3.5 million), less any amounts remaining of the Tranche A Committed Amount that the Funder did not pay as Claims Payments; plus an additional 300.0% of the Tranche B Committed Amount (i.e. 300.0% of $1.5 million), if the Claimholder exercises the Tranche B funding option, less any amounts remaining of the Tranche B Committed Amount that the Funder did not pay as Claims Payments;

(iii)

third, for each $10,000 in specified fees and expenses paid by the Funder under Phase I and Phase II and any amounts over each $10,000 of the Tranche A Committed Amount and the Tranche B Committed Amount (if the Claimholder exercises the Tranche B funding option), 0.01% of the total Proceeds from any recoveries after repayment of (i) and (ii) above, to the Funder; and

(iv)

thereafter, 100% to the Claimholder.

The Agreement provides that if no Proceeds are ever paid to or received by the Claimholder or its representatives and if the environmental permit is not issued, the Funder shall have no right of recourse or right of action against the Claimholder or its representatives, or any of their respective property, assets, or undertakings, except as otherwise specifically contemplated by the Agreement. If (a) Proceeds are paid to or received by the Claimholder or its representatives; (b) such Proceeds are promptly applied and/or distributed by the Claimholder or on behalf of the Claimholder in accordance with the terms of the Agreement; and (c) the amount received by the Funder as a result thereof is not sufficient to pay all of the Recovery Percentage and all of the amounts due to the Funder under the Agreement, then (provided that all of the Proceeds which the Funder will ever be entitled to have been paid to or received by the Funder), the Funder shall have no right of recourse or action against the Claimholder or its Representatives, or any of their property, assets, or undertakings, except as otherwise specifically contemplated by the Agreement. Pursuant to the Agreement, the Claimholder acknowledged the Funder's priority right, title, and interest in any Proceeds, including against any available collateral to secure its obligations under the Agreement, which security interest shall be first in priority as against all other security interests in the Proceeds. The Claimholder also acknowledged and agreed to execute and authorize the filing of a financing statement or similar and to take such other actions in such jurisdictions as the Funder, in its sole discretion, deems necessary and appropriate to perfect such security interest. The Agreement also includes representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions customary for comparable arrangements.

Amendment and Restatement (January 31, 2020)

On January 31, 2020, the Claimholder and the Funder entered into an Amended and Restated International Claims Enforcement Agreement (the "Restated Agreement"). The material terms and provisions that were amended or otherwise modified are as follows:

•

The Funder agreed to provide up to $2.2 million in Arbitration Support Funds for the purpose of paying the Claimholder's litigation support costs in connection with Subject Claim;

•

A closing fee of $0.2 million has been retained by the Funder in connection with due diligence and other transaction costs incurred by the Funder;

•

A warrant was issued to purchase our common stock which is exercisable for a period of five years beginning on the earlier of (a) the date on which the Claimholder ceases the Subject Claim for any reason other than a full and final Arbitral Award against the Claimholder or a full and final monetary settlement of the claims or (b) the date on which Proceeds are received and deposited into escrow. The exercise price per share is $3.99, and the Funder can exercise the warrant to purchase the number of shares of our common stock equal to the dollar amount of Arbitration Support Funds provided to us pursuant to the Restated Agreement divided by the exercise price per share (subject to customary adjustments and limitations); and

•

All other terms in the Restated Agreement are substantially the same as in the original Agreement.

During 2020, the Funder provided us with $2.0 million of the Arbitration Support Funds, and we incurred $0.2 million in related fees that were treated as an additional advance. Upon each funding, the proceeds were allocated between debt and equity for the warrants based on the relative fair value of the two instruments. As a result, there was an immediate expense of $1.1 million related to the derivative.

33

Table of Contents

Although the warrants only become exercisable upon the occurrence of future events, they are considered issued for accounting purposes and were valued using a binomial lattice model. The expected volatility assumption was based on the historical volatility of our common stock. The expected life assumption was primarily based on management's expectations of when the Warrants will become exercisable and the risk-free interest rate for the expected term of the warrant is based on the U.S. Treasury yield curve in effect at the time of measurement.

Second Amendment and Restatement (December 12, 2020)

On December 12, 2020, the Claimholder and the Funder entered into a Second Amended and Restated International Claims Enforcement Agreement (the "Second Restated Agreement") relating to the Subject Claim. Under the terms of the Second Restated Agreement, the Funder agreed to make Claims Payments in an aggregate amount not to exceed $20.0 million (the "Maximum Investment Amount"). The Second Restated Agreement requires the Funder to make Claims Payments in an aggregate amount no greater than $10.0 million for the purposes of pursuing the Subject Claim to a final award ("Phase III Investment Amount"). We also incurred $0.2 million in related fees, which were treated as an additional advance. The Second Restated Agreement includes the same representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions as in the original agreement.

Third Amendment and Restatement (June 14, 2021)

On June 14, 2021, the Claimholder and the Funder entered into a Third Amended and Restated International Claims Enforcement Agreement (the "Third Restated Agreement") relating to the Subject Claim. Under the terms of the Third Restated Agreement, the Funder has made and agreed to make Claims Payments in an aggregate amount not to exceed $25.0 million, an increase of $5.0 million (the "Incremental Amount"). The Third Restated Agreement requires the Claimholder to request $2.5 million of the Incremental Amount (the "First $2.5 Million"). Within 15 days after exhaustion of the First $2.5 Million, the Claimholder may either (a) request the remaining $2.5 million (the "Second $2.5 Million") of the Incremental Amount or (b) notify the Funder that the Claimholder has decided to self-fund the Second $2.5 Million. We also incurred $80,000 in related fees which were treated as an additional advance. This Second Restated Agreement includes the same representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions as in the original agreement. As of December 31, 2024, the Funder has made Claim Payments in the aggregate amount of $24.8 million.

The fair value of the obligation at December 31, 2024 and 2023 is $57.0 million and $52.1 million, respectively, with changes in the fair value of $4.8 million and $6.7 million for the years ended December 31, 2024 and 2023, respectively.

Litigation Financing Waiver and Consent

On March 6, 2023, the Claimholder and the Funder under the Agreement entered into a Waiver and Consent Agreement, pursuant to which, among other things, (i) the Funder provided a waiver and consent (i) to allow the Claimholder to fund certain costs and expenses arising from the Subject Claim from the Claimholder's own capital in an aggregate amount not to exceed $5.0 million, and (ii) Odyssey paid a $1.0 million nonrefundable waiver fee to the Funder.

Emergency Injury Disaster Loan

On June 26, 2020, we executed the standard loan documents required for securing an Economic Injury Disaster Loan (the "EIDL Loan") from the United States Small Business Administration (the "SBA"). The principal amount of the EIDL Loan is $0.2 million, with proceeds to be used for working capital purposes. Interest on the EIDL Loan accrues at the rate of 3.75% per annum and installment payments, including principal and interest of $731, are due monthly beginning 12 months from the date of the EIDL Loan. In 2021, the SBA extended this 12-month period, setting the first payment due date in December 2022. Per the agreement, payments reduce accrued interest first and are then applied against the principal. The balance of principal and interest is payable thirty years from the date of the promissory note.

As of both December 31, 2024 and 2023, the Company’s principal balance on the EIDL Loan amounted to $0.2 million and is recorded as Loans payable in the consolidated balance sheets.

Vendor Note Payable

We currently owe a vendor $0.5 million as an interest-bearing trade payable. This trade payable bears simple annual interest at a rate of 12.0%. As collateral, we granted the vendor a primary lien on certain of our equipment. The carrying value of this equipment is

34

Table of Contents

zero. This agreement matured in August 2018. Even though this agreement has matured, the creditor has not demanded payment. There are no covenant requirements to meet that would expose the Company to default situations.

Seller Note Payable

In December 2022, we entered into an Amended and Restated Purchase and Sale Agreement (“Purchase and Sale Agreement”) with the seller of certain marine equipment (“Seller”). Pursuant to the Purchase and Sale Agreement, Seller agreed to sell us the marine equipment, related tooling items and spares for $2.5 million. On or before the closing date, Odyssey paid the Seller $1.1 million for the acquisition of the assets. Pursuant to the Purchase and Sale Agreement, we paid the Seller the $1.4 million balance of the purchase price as a fully amortizing loan, bearing interest at a rate of 20% per annum, maturing on June 5, 2024 (the “Seller Note”). On April 4, 2023, the Company paid this loan in full.

AFCO Insurance Note Payable

On November 1, 2024, we executed the Premium Finance Agreement with AFCO Credit Corporation (“AFCO”). Pursuant to the Premium Finance Agreement, AFCO agreed to finance the Directors and Officers (“D&O”) Insurance premiums evidenced by the promissory note, bearing interest at a rate of 6.40% per annum, maturing on October 31, 2025.

On November 1, 2023, we executed the Premium Finance Agreement with AFCO. Pursuant to the Premium Finance Agreement, AFCO agreed to finance the D&O Insurance premiums evidenced by the promissory note, bearing interest at a rate of 4.95% per annum, maturing on October 31, 2024.

Critical Accounting Estimates

The discussion and analysis of our financial position and results of operations is based upon our financial statements, which have been prepared in accordance with US GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect our financial position and results of operations. See Note 2, Summary Of Significant Accounting Policies to the consolidated financial statements for a description of our significant accounting policies. Critical accounting estimates are defined as those that are reflective of significant judgment and uncertainties, and potentially result in materially different results under different assumptions and conditions. We have identified the following critical accounting estimates. We have discussed the development, selection and disclosure of these policies with our audit committee.

Derivative Financial Instruments

We evaluate all of our agreements to determine whether such instruments have derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. In evaluating the fair value of derivative financial instruments, there are numerous assumptions that management must make that may influence the valuation of the derivatives that would be included in the financial statements. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date.

As discussed in Note 7, Loans Payable, Note 8, Fair Value Measurements and Note 9, Derivative Financial Instruments to the consolidated financial statements, , we have certain litigation financing with detachable warrants, warrant liabilities, the OML Put Option and an embedded derivatives related to the 37N Note, March 2023 Notes and December 2023 Notes, included in the consolidated balance sheets at December 31, 2024 and 2023 that are considered derivative financial instruments.

The Litigation Financing agreement involved numerous amendments, significant non-cash financing, issuance of warrants, and issuance costs. Determination of the fair value of the derivative required significant judgment of and assumptions and estimates regarding the facts and circumstances regarding the potential liability. The fair value of the derivative is an inherently uncertain estimate because almost none of the inputs used in calculating the estimate–other than amounts funded–is objectively quantifiable. The inputs are based on management’s good faith but unavoidably subjective assumptions, judgments and estimates regarding the potential outcomes of the NAFTA arbitration case, the potential outcomes and award amounts conditional on Odyssey winning the arbitration, the potential repayment dates, the potential dates on which any proceeds from the arbitration might be received, and certain market inputs such as discount rates. The calculations based on these inputs resulted in a range of estimated fair values. The Company reported the midpoint of that range as the fair value at each relevant period. The estimate has changed each period based on management’s revised judgments and assumptions regarding timing and other inputs. The estimate reported as the fair value is sensitive to the methods, assumptions, judgments and estimates underlying the fair value calculations because the use of different probabilities regarding potential case outcomes, potential awards, repayment dates, discount rates, or other estimated assumptions, or another method of reporting the fair value from within the calculated range, could result in a significantly or materially different estimated fair value being reported.

35

Table of Contents

The fair values of the 2022 Warrants (as defined below) and the December 2023 Warrants, which are accounted for as derivative liabilities, were estimated using a Black-Scholes valuation model. The assumptions used in this model included the use of key inputs, including expected stock volatility, the risk–free interest rate, the expected life of the option and the expected dividend yield. Expected volatility is calculated based on the historical volatility of our Common Stock over the term of the warrant. Risk–free interest rates are calculated based on risk–free rates for the appropriate term. The expected life is estimated based on contractual terms as well as expected exercise dates. The dividend yield is based on the historical dividends issued by us. If the volatility rate or risk-free interest rate were to change, the value of the warrants would be impacted.

The fair value of the embedded derivative liability related to the share settled redemption feature recognized in connection with the 37N Note is determined using the with-and-without valuation method. As inputs into the valuation, we considered the type and probability of occurrence of certain events, the amount of the payments, the expected timing of certain events, and a risk-adjusted discount rate.

The OML Put Option was initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The OML Put Option valuation was based on the exercise period of the Equity Exchange Agreement, share price and volatility.

Investment in Unconsolidated Entities

We account for our interests in entities in which we are able to exercise significant influence over operating and financial policies, generally 50% or less ownership interest, under the equity method of accounting. In such cases, our original investments are recorded at cost and adjusted for our share of earnings, losses and distributions. We account for our interests in entities where we have virtually no influence over operating and financial policies under the cost method of accounting. In such cases, our original investments are recorded at the cost to acquire the interest and any distributions received are recorded as income. All investments are subject to our impairment review policy.

As discussed in Note 14, Related Party Transactions and Note 5, Investment in Unconsolidated Entities to the consolidated financial statements, the Company has a cost investment with a related party. The Company has entered into numerous agreements with the related party that required analysis of ASC 810-10 to determine that the Company was not the primary beneficiary. This analysis required judgment and review of the facts and circumstances to determine the proper accounting for this cost investment. We also reviewed the impairment guidance to determine any potential impairment of the investment. See Note 2, Summary of Significant Accounting Policies.

The current investment in unconsolidated entities accounted for under the equity method consists of a 6.97% interest in OML. We determined that the Company has a significant influence over OML’s operation due to the agreements to purchase additional interests in OML and the services we provide to OML which require our involvement in the decisions made over OML’s operations. As part of this acquisition, we entered into the OML Put Option to acquire additional interests in OML, which was determined to be an obligation to issue a variable number of shares that is predominantly based on variations in something other than the fair value of the company’s equity shares, within the scope of ASC 480. As such, the OML Put Option is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The OML Put Option valuation was based on the exercise period of the equity exchange agreement, share price and volatility. The Equity Exchange Agreement expired by its terms on January 3, 2025.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Disclosure controls are procedures designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, such as this Annual Report on Form 10-K, are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and principal financial officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision and with the participation of our management, including our CEO, who is currently also acting as our CFO for this purpose, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act as of the end of the period covered by this report. Based on that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were not effective as of December 31, 2024, as the result of the material weakness in our internal control over financial reporting discussed below, which is currently being remediated.

Notwithstanding the material weakness in our internal control over financial reporting, management believes the consolidated financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, the Company’s financial condition, results of operations and cash flows for each of the periods presented in this report in conformity with US GAAP.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f)and 15d-15(f). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. This process includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and

37

Table of Contents

directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

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

Due to the material weakness described below with respect to our internal control over financial reporting relating to the appropriate review of accounting positions for certain significant transactions, management has concluded that our internal control over financial reporting was not effective as of December 31, 2024.

Material Weakness in Internal Control over Financial Reporting

In connection with our evaluation for the year ended December 31, 2023, we identified a material weakness in our internal control over financial reporting as of December 31, 2023, relating to the appropriate review of accounting positions for certain significant transactions. Specifically, (a) the Company did not have sufficient resources with the adequate technical skills to identify and evaluate specific accounting positions and conclusions, and (b) the Company had inadequate processes and controls to ensure appropriate level of precision of review related to our financial statement footnote disclosures.

The material weakness resulted in material misstatement in our financial statements and disclosures for certain prior periods as set forth in our Comprehensive Form 10-K Report for the year ended December 31, 2023, and restatements were required of our previously released interim or audited consolidated financial statements for certain periods.

Remediation Efforts to Address Prior Material Weakness

Management is committed to maintaining a strong internal control environment. In response to the identified material weakness, management, with the oversight of the Audit Committee of the Board of Directors, has taken actions to remediate the material weakness in internal control over financial reporting by (a) engaging an Interim Controller with responsibility for monitoring the performance of controls by control owners, (b) continuing our evaluation of the skills and experience of our existing personnel with respect to public company experience and appropriate level of expertise in the respective areas of accounting, SEC financial reporting and associated internal controls commensurate with the type, volume and complexity of our accounting operations, transactions and reporting requirements, and (c) engaging accounting advisory consultants to provide additional depth and breadth in our SEC financial reporting and technical accounting functions, which consultants we expect to continue to utilize until we have ensured that our internal personnel have the appropriate expertise and experience. In addition, we have reinforced the importance of adherence to Company policies regarding control performance and related documentation with control owners, identified training and resource needs for control owners, and developed monitoring activities to validate the performance of controls by control owners.

The Company anticipates that the actions described above and resulting improvements in controls will strengthen the Company's processes, procedures and controls related to management's review of accounting positions for significant and complex transactions and will address the related material weakness. However, the material weakness cannot be considered remediated until the applicable control has operated for a sufficient period of time, and management has concluded, through testing, that the control is operating effectively.

Changes in Internal Control over Financial Reporting

Other than the ongoing remediation efforts of the material weakness described above, there were no changes during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Odyssey Marine Exploration, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Odyssey Marine Exploration, Inc. (a Nevada corporation) and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, changes in stockholders’ equity (deficit), and cash flows for each of the two years in the period ended December 31, 2024, 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 as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Going concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company incurred a loss from operations of $12 million during the year ended December 31, 2024, and as of that date, the Company’s current liabilities exceeded its current assets by $16 million and its total liabilities exceeded its total assets by $79 million. These conditions, along with other matters as set forth in Note 1, 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 1. 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 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate 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 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 they relate.

Accounting and Valuation of Litigation Financing

As described further in Note 9 to the consolidated financial statements, the Company entered into an agreement with a Funder to provide financial assistance in the Company’s claim against the United Mexican States under Chapter Eleven of the North American Free Trade Agreement (“NAFTA”) for violations of the Claimholder's rights under NAFTA. The Company determined that the financing arrangement was a derivative and should be measured at fair value each reporting period. The fair value of this derivative

instrument is recorded in “Litigation Financing and other” on the consolidated balance sheets. The determination of fair value of the litigation financing derivative liability requires management to make significant estimates and assumptions, including the probability of expected outcomes and the corresponding cash flows associated with such outcomes. We identified the accounting for and valuation of litigation financing as a critical audit matter.

The principal consideration for our determination that the accounting for and valuation of litigation financing is a critical audit matter is that the interpretation and application of the relevant accounting literature required significant auditor judgment, including the need to involve a subject matter expert, and the assumptions used in determining the valuation, specifically the discount rate and probabilities of outcome, involved a high degree of subjectivity.

Our audit procedures related to the accounting for and valuation of litigation financing derivative included the following, among others.

•

We evaluated the Company’s accounting memoranda and other documentation regarding application of the relevant accounting guidance.

•

We compared the underlying terms of the International Claims Enforcement Agreement and the Arbitration Award to management’s accounting memoranda and with the assistance of our internal subject matter expert, independently interpreted and applied the accounting literature to the Litigation financing agreement.

•

We evaluated the reasonableness of management’s assessment of probabilities of outcomes by reviewing publicly available information, discussing with management and legal counsel as well as the Company’s external counsel regarding the status of the case, and comparing the model to the legal terms of the agreement. We inspected minutes of the meetings of the Board of Directors and committees of the Board of Directors to search for any contradictory evidence which may indicate that the probabilities used by management might not be appropriate.

•

Withthe assistance of our valuation specialists, we evaluated the appropriateness of the model used in determining the fair value of derivative liabilities. We also performed an independent estimation of the discount rate from external market data and compared it to the discount rate management used in the model.

ODYSSEY MARINE EXPLORATION, INC. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – BUSINESS AND BASIS OF PRESENTATION

Organization

Odyssey Marine Exploration, Inc. and subsidiaries (the “Company,” “Odyssey,” “us,” “we” or “our”) is engaged in deep-ocean exploration. Our innovative techniques are currently applied to mineral exploration and other marine survey and contracted services. Our corporate headquarters are in Tampa, Florida.

Going Concern Consideration

We have experienced several years of net losses and may continue to do so. Our ability to generate net income or positive cash flows for the following twelve months is dependent upon financings, our success in developing and monetizing our interests in mineral exploration entities, generating income from exploration charters or collecting on amounts owed to us.

Our 2025 business plan requires us to generate new cash inflows to effectively allow us to perform our planned projects. We continually plan to generate new cash inflows through the monetization of our equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow becomes insufficient to meet our desired projected business plan requirements, we would be required to follow a contingency business plan based on curtailed expenses and fewer cash requirements.

In 2024, we received a payment of approximately $9.8 million arising from a residual economic interest in a salvaged shipwreck. In addition, in December 2024, we entered into the following agreements to partially address the Company's liquidity position for the next twelve months:

•

Securities Purchase Agreement - the Company entered into a Securities Purchase Agreement (“SPA”) pursuant to which the Company issued and sold an aggregate of 7,377,912 shares of common stock at a purchase price of $0.55 per share, for an aggregate purchase price of $4.1 million. Refer to Note 12, Stockholders’ Equity/(Deficit) for the terms and additional information on the Securities Purchase Agreement.

•

March 2023 Notes (as defined in Note 7, Loans Payable) - the Company entered into an Amendment to Note and Warrant Purchase Agreement (the “March 2023 NWPA Amendment”) on December 20, 2024, pursuant to which it, among other things, (a) extended the maturity of the March 2023 Notes to December 31, 2025. Refer to Note 7, Loans Payable for the terms and additional information on the March 2023 NWPA Amendment.

•

December 2023 Notes (as defined in Note 7, Loans Payable) - the Company entered into an Amendment to Note and Warrant Purchase Agreement (the “December 2023 NWPA Amendment”) on December 20, 2024, pursuant to which it, among other things, (a) extended the maturity of the March 2023 Notes to April 1, 2026. Refer to Note 7, Loans Payable for the terms and additional information on the December 2023 NWPA Amendment.

Our consolidated non-restricted cash balance at December 31, 2024, was $4.8 million. We had a working capital deficit at December 31, 2024, of $16.7 million. The total consolidated book value of our assets was approximately $18.5 million at December 31, 2024, which includes the cash balance of $4.8 million.

The factors noted above raise doubt about our ability to continue as a going concern. Although the steps taken by management, as outlined above, provide liquidity to the Company and position the Company to continue operating, the doubt about our ability to continue as a going concern has not been alleviated. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This summary of significant accounting policies of the Company is presented to assist in understanding our financial statements. The financial statements and notes are representations of the Company’s management who are responsible for their integrity and objectivity and have prepared them in accordance with our customary accounting practices.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, both domestic and international. Equity investments in which we exercise significant influence but do not control and of which we are not the primary beneficiary are accounted for using the equity method. All significant inter-company and intra-company transactions and balances have been eliminated. The portion of the consolidated subsidiaries not wholly owned by the Company and any related activity is eliminated through Non-controlling interests in the consolidated balance sheets and Net income (loss) attributable to non-controlling interests in the consolidated statements of operations. The results of operations attributable to the non-controlling interest are presented within equity and net income (loss) and are shown separately from the Company’s equity and net income attributable to the Company. Some of the existing inter-company balances, which are eliminated upon consolidation, include features allowing the liabilities of Exploraciones Oceánicas S. de R.L. de CV (“ExO”) and Oceanica Resources, S. de R.L. (“Oceanica”), majority owned subsidiaries of the Company, to be converted into additional equity of a subsidiary, which, if exercised, could increase the Company’s direct or indirect interest in the non-wholly owned subsidiaries.

Use of Estimates

Management used estimates and assumptions in preparing these consolidated financial statements in accordance with generally accepted accounting principles in the United States (“US GAAP”). Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could vary from the estimates that were used.

Revenue Recognition and Accounts Receivable

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of Accounting Standards Codification (“ASC”) Topic 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 Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

The Company currently generates revenues from service contracts with customers. Currently, there are two sources of revenue, marine services and operating and other services. The contracts for the marine services provide research, scientific services, marine operations planning, management execution and project management. These services are billed generally on a monthly basis and recognized as revenue as the services are performed or provided. The Company generally does not receive any upfront consideration for these services, and there is no variable consideration for the services. Costs associated with both marine and operating and other services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations and Research.

Accounts receivable are based on amounts billed to customers. We evaluate our accounts receivable to estimate an allowance for credit losses over the remaining life of the financial instrument. The remaining life of our financial assets is determined by considering contractual terms among other factors. We estimate an allowance for credit losses based on ongoing evaluations of the accounts and notes receivable, the related credit risk characteristics, and the overall economic and environmental conditions affecting the financial assets. Credit losses are charged off against the allowance when we believe the uncollectibility of the financial asset is confirmed. Subsequent recoveries, if any, are credited to the allowance once received. A credit loss expense, or benefit, is recorded within marketing, general and administrative expense in the Statement of Operations in an amount necessary to adjust the allowance for credit losses to our estimate as of the end of each reporting period. At December 31, 2024 and 2023 we determined no allowance was necessary. If we were to have a recorded allowance, the accounts receivable would be stated net of the recorded allowance.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and cash in banks and consists of deposits in one U.S. and one foreign bank. We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.The Company maintains certain of its cash balances in one U.S. bank, which at times, may exceed federally insured limits. The Company has not incurred and does not expect to incur any losses with respect to these balances. We limit investment of cash equivalents and investments to financial institutions with high credit ratings. Management believes it is not exposed to any significant credit risk regarding these accounts as it performs periodic reviews of the creditworthiness of the financial institutions the Company uses.

Bismarck Exploration License

The Company follows the guidance pursuant to Financial Accounting Standards Board (“FASB”) ASC 350, “Intangibles-Goodwill and Other” (“ASC 350”) in accounting for the exploration license held by Bismarck Mining Corporation, Ltd., (the “Bismarck Exploration License”). Management determined the rights to use the license to have an indefinite life. This assessment is based on the historical success of renewing the license every two years since 2006, and the fact that management believes there are no legal, regulatory, or contractual provisions that would limit the useful life of the asset. The Company was notified in November 2023 that the 2022 exploration license renewal application was approved. The most recent renewal was submitted in July 2024, and we expect to receive a response by June 2025. The Bismarck Exploration License is not dependent on another asset or group of assets that could potentially limit the useful life of the exploration license. We test the Bismarck Exploration License for impairment annually, and more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired, per the guidance of the ASC topic 350. We did not have any triggering events or impairments for the years ended December 31, 2024 or 2023.

Derivative Financial Instruments

From time to time, we may enter into a financial instrument that may contain a derivative. In evaluating the fair value of derivative financial instruments, there are numerous assumptions which management must make that may influence the valuation of the derivatives that would be included in the financial statements.

Derivative financial instruments consist of financial instruments or other contracts that contain a notional amount and one or more underlying variables (e.g., interest rate, security price or other variable), require a small or no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii) may be net-cash settled by the counterparty. As required by ASC 815 – Derivatives and Hedging, these instruments are required to be carried as derivative liabilities, at fair value, in our financial statements with changes in fair value reflected in our income.

As discussed in Note 9, Derivative Financial Instruments to the consolidated financial statements, we have certain litigation financing with detachable warrants that is included in "Litigation financing and other" on the consolidated balance sheets at December 31, 2024 and 2023. The litigation financing agreement involved numerous amendments, significant non-cash financing, issuance of warrants, and issuance costs requiring judgment of the facts and circumstances, in particular with respect to the determination of the fair value of the derivative. The fair value of the derivative at December 31, 2024, was based on amounts funded and management's good-faith estimates of the potential outcomes of enforcement and collection of the Arbitral Award, the potential outcomes conditional on Odyssey winning Mexico’s proceeding to set aside the Arbitral Award, the potential repayment date, and certain market variables.

The fair value of the derivative at December 31, 2023, was based on the amounts funded and management’s good-faith estimates of other inputs including the potential outcomes of the NAFTA case, potential repayment date, and certain market variables.

The Company determines the accounting classification of warrants it issues as either liability or equity classified by first assessing whether the warrants meet liability classification in accordance with ASC 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, then in accordance with ASC 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. After all relevant assessments, the Company concludes whether the warrants are classified as liability or equity. Liability classified warrants require fair value accounting at issuance and subsequent to initial issuance with all changes in fair value after the issuance date recorded in the Statements of Operations. Equity classified warrants only require fair value accounting at issuance with no changes recognized subsequent to the issuance date.

As of December 31, 2024, the 2022 Warrants, the March 2023 Warrants and the December 2023 Warrants were determined to meet the definition of derivative liability, and their respective fair value was estimated using a Black-Scholes valuation model.

The 37N Note was determined to include an embedded derivative liability related to the share settled redemption feature of the Note in accordance with ASC 815. The embedded derivative fair value is determined using the with-and-without valuation method. In

October 2024, the remainder of the indebtedness under the 37N Note was converted into shares of the Company's common stock, pursuant exercise notices delivered by 37North. Refer to Note 7, Loans Payable, for further information on the conversion.

During December 2024, the Company entered into amendments of the March 2023 Notes and the December 2023 Notes that resulted in additional embedded liabilities in those notes. Refer to Note 9, Derivative Financial Instruments, for details on such transactions.

Investment in Unconsolidated Entities

As discussed in Note 5, Investment in Unconsolidated Entities, the Company has cost basis method investments and an equity method investment with related parties. We account for the investments we make in certain legal entities in which equity investors do not have (1) sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (2) as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity’s economic performance, or (3) the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. The Company has entered into agreements with a certain related parties that required analysis of ASC 810-10 to determine if the investment is considered a variable interest entity (“VIE”). If the investment is determined to be a VIE, then the Company evaluates whether it is considered the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to direct the activities that most significantly impact the VIE’s economic performance; and (ii) has the obligation to absorb losses or the right to receive benefits from the VIE. We determine whether any of the entities in which we have made investments is a VIE at the start of each new venture and if a reconsideration event has occurred. At such times, we also consider whether we must consolidate a VIE and/or disclose information about our involvement in a VIE. This analysis required judgment and review of the facts and circumstances to determine the proper accounting for the cost and equity method investments. A reporting entity must consolidate a VIE if that reporting entity has a variable interest (or combination of variable interests) that will absorb a majority of the VIE’s expected losses, receive a majority of the VIE’s expected residual returns, or both. A reporting entity must consider the rights and obligations conveyed by its variable interests and the relationship of its variable interests with variable interests held by other parties to determine whether its variable interests will absorb a majority of a VIE’s expected losses, receive a majority of the VIE’s expected residual returns, or both. For investments in VIEs in which the Company is considered the primary beneficiary, the assets, liabilities and results of operations of the VIE are included in the Company’s consolidated financial statements. As of December 31, 2024 and 2023, there were no VIEs for which the Company was the primary beneficiary. We also review these investments for any potential impairment annually.

We use the equity method to account for investments in companies if our investment provides us with the ability to exercise significant influence over the operating and financial policies of the investee. Our Consolidated Statement of Operations includes our Company’s proportionate share of the net income or loss of these companies. It is our policy to account for our share of the investee’s net income or loss using a three-month lag period with an estimate of the most recent quarter results, if final information has not been received. Our judgment regarding the level of influence over each equity method investee includes considering key factors, such as our ownership interest, representation of the board of directors, participation in policy-making decisions, other commercial arrangements and material intercompany transactions.

We eliminate from our financial results all significant intercompany transactions, including the intercompany portion of transactions with equity method investees.

Long-Lived Assets

Property and equipment is stated at historical cost. Depreciation is calculated using the straight-line method at rates based on the assets' estimated useful lives which are normally three years for computers and peripherals, five years for furniture and office equipment and between five and ten years for marine equipment. Items that may require major overhauls (such as marine equipment) that enhance or extend the useful life of these assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. All other repairs and maintenance are expensed when incurred.

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed using undiscounted net cash flows related to the long-lived assets. If such assets are considered to be impaired, the impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. There was no impairment recorded to long-lived assets as of December 31, 2024 or 2023, respectively.

Fair Value Measurements

Financial instruments consist of cash, evidence of ownership in an entity, and contracts that both (i) impose on one entity a contractual obligation to deliver cash or another financial instrument to a second entity, or to exchange other financial instruments on potentially unfavorable terms with the second entity, and (ii) conveys to that second entity a contractual right (a) to receive cash or

52

Table of Contents

another financial instrument from the first entity, or (b) to exchange other financial instruments on potentially favorable terms with the first entity. Accordingly, our financial instruments consist of cash and cash equivalents, accounts receivable, equity securities, accounts payable, accrued liabilities, derivative financial instruments and loans payable. The carrying amounts of cash and cash equivalents, accounts payable and accrued liabilities approximate their fair values due to their short maturities. Loans payable are measured at fair value based on valuation techniques using observable inputs other than Level 1 quoted prices in active markets and, accordingly, these estimates are not necessarily indicative of the amounts that we could realize in a current market exchange. We carry derivative financial instruments at fair value as is required under current accounting standards. Derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets.

We adopted ASC Topic 820 for certain financial instruments measured as fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with US GAAP and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value.

Fair Value Hierarchy

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). These tiers include:

The three levels of inputs that may be used to measure fair value are as follows:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities. Level 2 inputs also include non-binding market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions.

Level 3. Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs also include non-binding market consensus prices or non-binding broker quotes that we were unable to corroborate with observable market data.

Leases

When we enter into a new arrangement, we must determine, at the inception date, whether the arrangement contains a lease. This determination generally depends upon whether the arrangement conveys to us the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to us if we obtain the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset.

If a lease exists, we must then determine the separate lease and non-lease components of the arrangement. Each right to use an underlying asset conveyed by a lease arrangement should generally be considered a separate lease component if it both: (i) can benefit us without depending on other resources not readily available to us and (ii) does not significantly affect and is not significantly affected by other rights of use conveyed by the lease. Aspects of a lease arrangement that transfer other goods or services to us but do not meet the definition of lease components are considered non-lease components. The consideration owed by us pursuant to a lease arrangement is generally allocated to each lease and non-lease component for accounting purposes. However, we have elected to not separate lease and non-lease components. Each lease component is accounted for separately from other lease components, but together with the associated non-lease components.

For each lease, we must then determine:

•

The lease term – The lease term is the period of the lease not cancellable by us, together with periods covered by: (i) renewal options we are reasonably certain to exercise or that are controlled by the lessor and (ii) termination options we are reasonably certain not to exercise.

•

The present value of lease payments is calculated based on:

o

Lease payments – Lease payments include certain fixed and variable payments, less lease incentives, together with amounts probable of being owed by us under residual value guarantees and, if reasonably certain of being paid, the cost of certain renewal options and early termination penalties set forth in the lease arrangement. Lease payments exclude consideration that is: (i) not related to the transfer of goods and services to us and (ii) allocated to the non-lease

53

Table of Contents

components in a lease arrangement, except for the classes of assets where we have elected to not separate lease and non-lease components.

o

Discount rate – The discount rate must be determined based on information available to us upon the commencement of a lease. Lessees are required to use the rate implicit in the lease whenever such rate is readily available; however, if the implicit rate a lease is not readily determinable, we would use the hypothetical incremental borrowing rate we would have to pay to borrow an amount equal to the lease payments, on a collateralized basis, over a timeframe similar to the lease term.

•

Lease classification – In making the determination of whether a lease is an operating lease or a finance lease, we consider the lease term in relation to the economic life of the leased asset, the present value of lease payments in relation to the fair value of the leased asset and certain other factors, including the lessee’s and lessor’s rights, obligations and economic incentives over the term of the lease.

Generally, upon the commencement of a lease, we will record a lease liability and a right-of-use (“ROU”) asset. However, we have elected, for certain classes of underlying assets with initial lease terms of twelve months or less (known as short-term leases), to not recognize a lease liability or ROU asset. Lease liabilities are initially recorded at lease commencement as the present value of future lease payments. ROU assets are initially recorded at lease commencement as the initial amount of the lease liability, together with the following, if applicable: (i) initial direct costs and (ii) lease payments made, net of lease incentives received, prior to lease commencement.

Over the lease term, we increase our lease liabilities using the effective interest method and decrease our lease liabilities for lease payments made. We generally amortize the ROU asset over the shorter of the estimated useful life or the lease term and assess our ROU assets for impairment, similar to other long-lived assets.

For operating leases, a single lease cost is generally recognized in the Consolidated Statements of Operations on a straight-line basis over the lease term.

Foreign Currency

The Company’s functional and reporting currency is U.S. dollars. Foreign currency denominated assets and liabilities are remeasured into U.S. dollars using the exchange rates in effect at the balance sheet date. Results of operations and cash flows of businesses conducted in foreign currency are remeasured using the average exchange rates throughout the period. The effect of exchange rate fluctuations on the remeasurement of assets and liabilities is included in Other expense in the Consolidated Statement of Operations, and amounted to a $1.1 million gain and a $0.7 million loss for the years ended December 31, 2024 and 2023, respectively.

Earnings Per Share (“EPS”)

Basic EPS has been computed pursuant to FASB ASC Topic 260, Earnings Per Share, and is computed by dividing income or loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options, restricted stock units and warrants and use the if-converted method to compute potential common shares from preferred stock, convertible notes or other convertible securities.

Dilutive common stock equivalents include the dilutive effect of in-the-money stock equivalents, which are calculated based on the average share price for each period using the treasury stock method, excluding any common stock equivalents if their effect would be anti-dilutive. The potential common shares in the following tables represent potential common shares from outstanding options, restricted stock awards, convertible notes and other convertible securities that were excluded from the calculation of diluted EPS during periods due to having an anti-dilutive effect are:

As further discussed in Note 5, Investment In Unconsolidated Entities, the Equity Exchange Agreement expired on January 3, 2025. As a result, the numerator and denominator adjustments related to the Equity Exchange Agreement will not have an effect on diluted earnings per share on any subsequent period.

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.

Operations and research

Operations and research expenses are charged to operations as incurred.

Stock-based Compensation

Our stock-based compensation is recorded in accordance with the guidance in the ASC Topic 718 Stock-Based Compensation. All share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense on a straight-line basis over the requisite service period for the entire award. The amount of compensation costs recognized at any date is to be at least equal to the portion of grant-date value of the award that is vested as of that date. For performance-based share awards, the Company recognizes expense when it is determined the performance criteria are probable of being met. The probability of vesting is reassessed at each reporting date and compensation cost is adjusted using a cumulative catch-up adjustment. Forfeitures are recognized in compensation cost when they occur. Benefits or deficiencies of tax deductions in excess of recognized compensation costs are reported within operating cash flows.

See Note 12, Stockholders’ Equity/(Deficit) for further discussion related to the Company’s share-based compensation plans.

Segment Reporting

We evaluate the products and services that produce our revenue and the geographical regions in which we operate to determine reportable segments in accordance with ASC 280 – Segment Reporting. Based on that evaluation, we have determined that we have only one operating segment.

See Note 17, Segment Reporting for further discussion related to the segment information.

Recent Accounting Pronouncements

In 2024, we adopted Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, on a retrospective basis. The amendments are intended to increase reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. Refer to Note 17, Segment Reporting for further information.

In December 2023, the FASB issued new guidance on income tax disclosures (ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”). Among other requirements, this update adds specific disclosure requirements for income taxes, including: (1) disclosing specific categories in the rate reconciliation and (2) providing additional information for reconciling items that meet quantitative thresholds. The guidance is effective for fiscal years beginning after December 15, 2024, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2023-09 on the Company’s consolidated financial statements and disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses”. The guidance in ASU 2024-03 requires public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses including purchases of inventory; employee compensation; and depreciation, amortization and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is currently evaluating the provisions of this guidance and assessing the potential impact on the Company’s financial statement disclosures.

Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company’s financial statements.
