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”)

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. On September 5, 2024, the Company entered into amendments pursuant to which the maturity date was extended from September 6, 2024, to December 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 $3,742,362 and classified the warrants as equity and debt discount of the March 2023 Note. On January 30, 2024, the March 2023 Warrant was amended to add a cashless exercise provision. Due to that amendment, the Company determined that the March 2023 Warrant meets the definition of a derivative and is 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, beginning in the first quarter of 2024, the March 2023 Warrant is recognized as a derivative liability and is subsequently measured at fair value with changes recognized in earnings in the period incurred.

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 were being amortized over the term of the March 2023 Note Purchase Agreement and charged to interest expense. In connection with the December 2024 amendment discussed below, any unamortized debt discount was written off to interest expense.

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. In addition, the warrants are considered a standalone liability-classified instrument, therefore they are unlinked from the debt and considered separate instruments. The repricing of the warrants was measured to fair value based on the new prices as of the amendment date and subsequently remeasured at each reporting date. 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.

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 $11.6 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 $0.9 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.

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 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, 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.

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 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. In addition, the warrants are considered a standalone liability-classified instrument, therefore they are unlinked from the debt and considered separate instruments. The repricing of the warrants was measured to fair value based on the new prices as of the amendment date and subsequently remeasured at each reporting date. At December 31, 2024, the debt instrument and embedded derivatives were recorded on the consolidated balance sheets at fair value of $6.7 million, inclusive of $0.2 million of accrued interest, in Loans payable, and $0.3 million, in debt derivative, respectively.

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 $6.0 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.

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.

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 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.

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.

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 in the amount of $565,512 equally over an 11-month period, 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.

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 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 $0.4 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.

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.

On February 28, 2023, Odyssey issued a $0.3 million 11.0% Promissory Note to Galileo NCC Inc (“Galileo”). The Promissory Note was payable on April 1, 2023. On March 6, 2023, Odyssey repaid this note payable in full with proceeds from the issuance of the DP SPV Note.

On March 11, 2015, we issued promissory notes to Minera del Norte, S.A. de C.V. (“MINOSA”) with a principal amount of $14.75 million (the “Minosa 1 Note”). During December 2017, MINOSA transferred this debt to its parent company.

On August 10, 2017, we entered into a Note Purchase Agreement (the “Minosa Purchase Agreement”) with MINOSA. Pursuant to the Minosa Purchase Agreement, MINOSA agreed to loan Odyssey Marine Enterprises Ltd. up to $3.0 million. By January 2018, the Company borrowed the entire $3.0 million against this facility, and Epsilon Acquisitions LLC (“Epsilon”) assigned $2.0 million of its previously held debt to MINOSA.

During December 2017, MINOSA transferred this indebtedness to its parent company. On July 15, 2021, $0.4 million of this indebtedness with accumulated interest of $0.2 million was transferred to James Pignatelli, a director of the Company, under the same terms as the original agreement, and that indebtedness continues to be convertible at a conversion price of $4.35 per share. This transaction was reviewed and approved by the independent members of the Company’s Board.

On March 3, 2023, Odyssey, Altos Hornos de México, S.A.B. de C.V. (“AHMSA”), MINOSA and Phosphate One LLC (f/k/a Penelope Mining LLC, “Phosphate One” and together with AHMSA and MINOSA, the “AHMSA Parties”) entered into Settlement, Release and Termination Agreement (the “Termination Agreement”).
