On March 3, 2025, the Company repaid the remaining balance of this loan in full. See further discussion within Note 17, Subsequent Events.

At December 31, 2024 and 2023, the combined loan and accrued interest balance was $680,513 and $497,052, respectively. A new effective interest rate of approximately 48.6% was established during the second quarter of 2023 based on the carrying value of the revised cash flows.

Interest and accretion expense was $721,061 and $853,809 for the years ended December 31, 2024 and 2023 respectively. The loan is collateralized by all of Pineapple Energy LLC’s personal property and assets.

SUNation Short-Term and Long-Term Notes

In connection with the SUNation acquisition, on November 9, 2022, the Company issued a $5,000,000 Short-Term Limited Recourse Secured Promissory Note (the “Short-Term Note”) and a $5,486,000 Long-Term Promissory Note (the “Long-Term Note”). The $5,000,000 Short-Term Note was secured by a pledge by the Company and Merger Sub of the equity of SUNation purchased under the Transaction Agreement and was scheduled to mature on August 9, 2023. It carried an annual interest rate of 4% until the three-month anniversary of issuance, 8% thereafter until the six-month anniversary of issuance, then 12% thereafter until the Short-Term Note was paid in full. On June 1, 2023 the Company used funds from the Decathlon Financing to repay the Short-Term Note in full. The repayment of Short-Term Note has been recorded as a debt extinguishment as the Company is relieved of its obligation under the Short-Term Note and the related pledge by the Company of the equity of SUNation to secure the repayment of the Short-Term Note has been terminated. Since the Short-Term Note was with a related party, the Company recorded a capital contribution of $36,291 based on the difference between the carrying amount and reacquisition price of the Short-Term Note.

The $5,486,000 Long-Term Note is unsecured and matures on November 9, 2025. It carries an annual interest rate of 4% until the first anniversary of issuance, then 8% thereafter until the Long-Term Note is paid in full. Interest is due annually on each December 31^st. The Company was unable to make the second and third interest payments totaling $250,703 and $460,194 due on December 31, 2023 and 2024, respectively. The Company was required to make a principal payment of $2,740,000 on November 9, 2024. The Company is not permitted to make any payments under the Long-Term Note unless Decathlon (defined below) has provided prior written consent to such payment pursuant to the Loan Agreement. Pursuant to that certain subordination letter dated May 31, 2023, each holder of the Long-Term Note has subordinated all payments under the Long-Term Note to the obligations owed to Decathlon under the Loan Agreement (the “Decathlon Obligations”) and has agreed that, until the Decathlon Obligations have been paid in full, any payment under the Long-Term Note is subject to Decathlon’s prior written consent. As the debt was part of the SUNation purchase price allocation, the Company assessed the fair market value of the debt instrument at $4,830,533 at the asset acquisition date (a non-recurring Level 3 fair value input). The Company accretes the value of the debt over its life at a discount rate of approximately 11.2%. The Long-Term Note may be prepaid at the Company’s option at any time without penalty.

On March 13, 2025, the Company paid the aforementioned unpaid interest totaling $710,897. See further discussion within Note 14, Subsequent Events.

The balance of the Long-Term Note recorded at December 31, 2024 and 2023 was $6,076,978 and $5,499,716, respectively. Interest and accretion expense related to the notes totaled $577,262 and $779,489 for the years ended December 31, 2024 and 2023, respectively.

Decathlon Fixed Loan

On June 1, 2023, the Company entered into a Revenue Loan and Security Agreement (the “Loan Agreement”) with Decathlon Specialty Finance, LLC (“Decathlon”). The Loan Agreement provides for a loan facility for the Company in the maximum amount of $7.5 million with a maturity date of June 1, 2027 (the “Decathlon Fixed Loan”), with the full amount being advanced to the Company upon execution of the Loan Agreement. The Decathlon Fixed Loan contains customary conditions, representations and warranties, affirmative and negative covenants, mandatory prepayment provisions and events of default. The advances are secured by all present and hereafter acquired property of the Company.

At issuance of the Loan Agreement, the Company concluded that the potential acceleration of amounts outstanding under the Loan Agreement upon an event of default included a substantial premium and met the requirement to be bifurcated and recorded as a derivative liability at fair value at inception and at the end of each quarterly reporting period. However, based on management’s estimates of the likelihood of certain events, the embedded derivative liability had no fair value at issuance and at the end of December 31, 2023. As of December 31, 2024, the fair value of this embedded derivative liability was estimated to be $24,800 and was recorded within current liabilities. For the year ended December 31, 2024, the Company recorded a loss

of $24,800 from the change in fair value of the derivative liability, which is included in Other (expense) income, net in the consolidated statements of operations and comprehensive loss.

The Decathlon Fixed Loan is repayable in fixed monthly payments, which generally aggregate to $960,000 that was paid in 2023, $2,220,000 payable in 2024, $2,580,000 payable in 2025, $2,760,000 payable in 2026 and $3,480,000 payable in 2027 to the maturity date. All outstanding advances and interest under the Loan Agreement are due at maturity on June 1, 2027 (unless accelerated upon a change of control or the occurrence of other events of default). Interest accrues on the amounts advanced pursuant to the Loan Agreement at such rate as is necessary to generate an amount equal to the Minimum Interest, which is defined in the Loan Agreement as the following multiple of the advanced amount depending on the period during which all amounts due under the Loan Agreement are paid: (i) 0.25 times if on or before 12 months after the Effective Date; (ii) 0.35 times if after 12 months and on or before 24 months after the Effective Date; (iii) 0.50 times if after 24 months and on or before 36 months after the Effective Date; and 0.60 times if after 36 months after the Effective Date. The Company may at its option prepay the advance(s) and accrued but unpaid interest from time to time without penalty or premium (other than payment of the Minimum Interest).

On March 3, 2025, the Company repaid the remaining balance of this loan in full. See further discussion within Note 17, Subsequent Events.

The Company incurred an aggregate of $348,065 in debt issuance costs that are recorded as a discount and are amortized using the effective interest method over the life of the Decathlon Fixed Loan using an effective interest rate of 21%. At December 31, 2024 and 2023, the combined loan and accrued interest balance was $6,586,325 and $7,408,925, respectively, and the unamortized debt issuance costs balance was $173,193 and $280,856, respectively. The Company recorded interest expense of $1,505,063 and $936,135 for the years ended December 31, 2024 and 2023, respectively.

Conduit Capital Bridge Loan

On July 22, 2024, the Company obtained bridge loan financing for working capital purposes from Conduit Capital U.S. Holdings LLC (“Conduit”), an unaffiliated lender (the “Original Conduit Note”). On such date, Conduit loaned the principal sum of $500,000 to the Company on an original issue (“OID”) basis of 20% and accordingly, Conduit advanced $400,000 to the Company (the “Initial Conduit Loan”). The loans due to Conduit will accrue interest on the unpaid principal amount, without deduction for the OID, at an annual rate of 20%; provided that payment in full on the Conduit Maturity Date (as defined below) satisfies the interest accrual on the loans from initial issuance to the Conduit Maturity Date. The Initial Conduit Loan provided the Company with an option to request from Conduit additional advances for working capital on identical terms, conditions and interest rate as the Initial Conduit Loan on an OID basis, up to an aggregate principal sum of $500,000, and Conduit shall have the right, without commitment or obligation, to make such requested loan(s) by advancing 80% percent of the principal thereof. All such loans are secured by a pledge of all of the Company’s assets. As a condition to such loan(s), the Company agreed to cause the nomination of a designee of Conduit for election to its Board of Directors.

The loans due to Conduit will become due on July 21, 2025 (the “Conduit Maturity Date”). In accordance with the terms of the loan agreements with Conduit, if the Company consummates one or more equity offerings prior to the Conduit Maturity Date in which it derives aggregate gross proceeds of at least $3.15 million, it will be required to repay the unpaid principal balance of the Initial Conduit Loan, including the OID, simultaneous with the closing(s) of such offering(s). Further, if the Company consummates one or more equity offerings prior to the Conduit Maturity Date in which it derives aggregate gross proceeds of at least $4.4 million, the Company will be required to repay the entire unpaid principal amount of all loans due to Conduit, including the OID, simultaneous with the closing(s) of such offering(s).

At issuance of the Original Conduit Note, the Company concluded that the potential acceleration of amounts outstanding under the loan agreements with Conduit upon an event of default or if the Company consummates one or more equity offerings meeting certain criteria (as noted above) included a substantial premium and met the requirement to be bifurcated and recorded as a derivative liability at fair value at inception and revalued at the end of each quarterly reporting period. The Company determined the initial fair value of this embedded derivative liability to be $8,080 and recorded a corresponding debt discount. As of December 31, 2024, the fair value of this embedded derivative liability was estimated to be $28,360 and was recorded within current liabilities. For the year ended December 31, 2024, the Company recorded a loss of $19,776 from the change in fair value of the derivative liability, which is included in “Other (expense) income, net" in the consolidated statements of operations and comprehensive loss.

The Company incurred $18,150 in debt issuance costs in connection with the Initial Conduit Loan that were recorded as a discount and initially amortized using the effective interest method over the life of the Initial Conduit Loan along with the OID of $100,000 and initial fair value of the embedded derivative liability using an effective interest rate of approximately 29.1%.

On September 9, 2024, the Company and Conduit entered into an Amended and Restated Convertible Secured Note (the “First Amended Conduit Note”) which amended the Original Conduit Note, which provided for an additional principal advance of $120,000 (the “Second Conduit Advance”). The First Amended Conduit Note also provides that Conduit may convert all or any portion of the Second Conduit Advance and all accrued but unpaid interest thereon into a number of shares (the “Conduit Note Conversion Shares”) of the Company’s common stock calculated as the total dollar amount to be converted divided by $22.50 ($0.45 prior to the Reverse Stock Splits) (the “Conversion Price”). The Company analyzed the changes made in the First Amended Conduit Note under ASC 470-50 to determine if extinguishment accounting was applicable. Under ASC 470-50-40-10, a modification or an exchange that adds or eliminates a substantive conversion option as of the conversion date is always considered substantial and requires extinguishment accounting. Since the First Amended Conduit Note added a substantive conversion option, extinguishment accounting is applicable. In accordance with the extinguishment accounting guidance, the Company recorded a loss on extinguishment of $35,657 which represents the difference between (a) the fair value of the modified loans due to Conduit less the net cash proceeds received from the Second Conduit Advance and (b) the carrying amount of the loans due to Conduit immediately prior to the Second Conduit Advance.

On September 23, 2024, the Company and Conduit entered into a further amended and restated convertible secured credit note (the “Second Amended Conduit Note”), which amends and restates the First Amended Conduit Note. Under the terms of the Second Amended Conduit Note, Conduit loaned an additional principal sum of $380,000 to the Company (the “Third Conduit Advance”) on an OID basis of 20%. Additionally, pursuant to the Second Amended Conduit Note, Conduit was granted a demand registration right, which is in addition to the piggyback registration rights set forth in the First Amended Conduit Note, which registration rights are inclusive of all convertible shares issuable for the Second Conduit Advance and Third Conduit Advance, if converted; however, all out of pocket costs and expenses incurred in connection with this demand registration right shall borne by Conduit. The Third Conduit Advance, together with all accrued but unpaid interest thereon, are convertible into shares of common stock at the Conversion Price. The Second Amended Conduit Note represented a modification under ASC 470-50 as the First Amended Conduit Note and the Second Amended Conduit Note are not substantially different. A new effective interest rate of approximately 22.9% was established following the Third Conduit Advance based on the carrying value of the revised cash flows.

Notwithstanding anything to the contrary as set forth in the Conduit Note or any tranche or amendment related thereto, in no event shall the OID, together with interest payable under the Conduit Note or such other documents related thereto, exceed an aggregate of twenty percent on the then outstanding principal sum, except in the event of a default, which shall include an additional 5% on the then outstanding principal sum.

On February 28, 2025, the Company paid the $1,000,000 total loan balance to Conduit as the Company had gross proceeds from equity offerings in excess of $4.4 million. See further discussion in Note 17, Subsequent Events.

At December 31, 2024 and 2023, the loan balance was $1,000,000 and $0, respectively, and the unamortized debt issuance costs balance was $119,389 and $0, respectively. The Company recorded interest and accretion expense of $73,689 for the year ended December 31, 2024.

MBB Energy Bridge Loan

On July 22, 2024, the Company obtained bridge loan financing for working capital purposes from MBB Energy, LLC (“MBB”), an affiliate and related party of the Company (the “Original MBB Note”). On such date, MBB loaned the principal sum of $500,000 to the Company on an OID basis of 20% and accordingly, MBB advanced the sum of $400,000 to the Company (the “Initial MBB Loan”). The loans due to MBB will accrue interest on the unpaid principal amount, without deduction for the OID, at an annual rate of 20%; provided that payment in full on the MBB Maturity Date (as defined below) satisfies the interest accrual on the loans from initial issuance to the MBB Maturity Date. The Company may request that MBB provide additional advances for working capital on identical terms, conditions and interest rate as the Initial MBB Loan on an OID basis, up to an aggregate principal sum of $500,000, and MBB shall have the right, without commitment or obligation, to make such requested loan(s) by advancing 80% percent of the principal thereof. All such loans are secured by a pledge of all of the Company’s assets. MBB has granted Conduit the exclusive right to enforce MBB’s loans on MBB’s behalf.

The loans due to MBB will become due on July 21, 2025 (the “MBB Maturity Date”). In accordance with the terms of the loan agreements with MBB, if the Company consummates one or more equity offerings prior to the MBB Maturity Date in which it derives aggregate gross proceeds of at least $3.15 million, it will be required to repay the unpaid principal balance of the Initial MBB Loan, including the OID, simultaneous with the closing(s) of such offering(s). Further, if the Company consummates one or more equity offerings prior to the MBB Maturity Date in which the Company derives aggregate gross proceeds of at least $4.4 million, the Company will be required to repay the entire unpaid principal amount of all loans due to MBB, including the OID, simultaneous with the closing(s) of such offering(s).

At issuance of the Original MBB Note, the Company concluded that the potential acceleration of amounts outstanding under the loan agreements with MBB upon an event of default or if the Company consummates one or more equity offerings meeting certain criteria (as noted above) included a substantial premium and met the requirement to be bifurcated and recorded as a derivative liability at fair value at inception and at the end of each quarterly reporting period. The Company determined the initial fair value of this embedded derivative liability to be $8,080 and recorded a corresponding debt discount. As of December 31, 2024, the fair value of this embedded derivative liability was estimated to be $29,121 and was recorded within current liabilities. For the year ended December 31, 2024, the Company recorded a loss of $21,041 from the change in fair value of the derivative liability, which is included in “Other (expense) income, net" in the consolidated statements of operations and comprehensive loss.

The OID of $100,000 was recorded as a discount and initially amortized using the effective interest method over the life of the Initial MBB Loan along with the initial fair value of the embedded derivative liability using an effective interest rate of approximately 24.3%.

On August 16, 2024, MBB provided an additional principal advance of $500,000 (the “Second MBB Advance”). The Second MBB Advance represented a modification under ASC 470-50. A new effective interest rate of approximately 24.1% was established following the Second MBB Advance based on the carrying value of the revised cash flows.

Notwithstanding anything to the contrary as set forth in the MBB Note or any tranche or amendment related thereto, in no event shall the OID, together with interest payable under the MBB Note or such other documents related thereto, exceed an aggregate of twenty percent on the then outstanding principal sum, except in the event of a default, which shall include an additional 5% on the then outstanding principal sum.

On February 28, 2025, the Company paid the $1,000,000 loan balance to MBB as the Company had gross proceeds from equity offerings in excess of $4.4 million. See further discussion in Note 17, Subsequent Events.
