Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned operating subsidiaries. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2024 included on the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (“SEC”) on April 15, 2025. The accompanying condensed consolidated balance sheet at December 31, 2024 has been derived from the audited balance sheet at December 31, 2024 contained in the above-referenced Form 10-K. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and accounts have been eliminated. Use of Estimates The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company uses estimates based on the best information available in recording transactions and balances resulting from operations. Actual results could materially differ from those estimates. The Company’s estimates consist principally of allowances for credit losses, revenue recognition on commercial projects based on percentage of completion, asset impairment evaluations, accruals for compensation plans, lower of cost or net realizable value, inventory adjustments, fair value measurements, provisions for income taxes and deferred taxes, depreciable lives of fixed assets, and amortizable lives of intangible assets. Cash, Restricted Cash and Cash Equivalents For purposes of the condensed consolidated statements of cash flows, the Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. The Company may invest in short-term money market funds that are not considered to be bank deposits and are not insured or guaranteed by the federal deposit insurance company (“FDIC”) or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible to lose money investing in these funds. Total cash equivalents invested in short-term money market funds was $883,328 and $368,138 as of September 30, 2025 and December 31, 2024, respectively. The $288,948 of restricted cash and cash equivalents on the balance sheet as of September 30, 2025 are funds that can only be used to support the legacy Communications Systems, Inc. (“CSI”) business (which had merged with and into Pineapple Energy, Inc. in March 2022 (and Pineapple Energy, Inc.’s name was changed to SUNation Energy Inc. in November 2024, each as previously disclosed and described more fully in prior annual and quarterly reports)), and will be distributed to holders of the Company’s contingent value rights (“CVRs”) and cannot be used to support the working capital needs of the SUNation Energy business. Accounts Receivable, Net Accounts receivable are recorded at their net realizable value and are not collateralized. Accounts receivable include amounts earned less payments received and allowances for credit losses. Management continually monitors and adjusts its allowances associated with the Company’s receivables to address any credit risks associated with the accounts receivable and periodically writes off receivables when collection is not considered probable. The Company does not charge interest on past due accounts. When uncertainty exists as to the collection of receivables, the Company records an allowance for credit losses and a corresponding charge to credit loss expense. Inventories, Net Inventories, which consist primarily of materials and supplies used in the installation of solar systems, are stated at the lower of cost or net realizable value, with costs computed on a weighted average cost basis. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net realizable values when they are determined to be less than cost. The inventory reserve was $288,546 and $226,439 at September 30, 2025 and December 31, 2024, respectively. Property, Plant and Equipment, net Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method. Maintenance and repairs are charged to operations and additions or improvements are capitalized. Items of property sold, retired or otherwise disposed of are removed from the asset and accumulated depreciation accounts and any gains or losses on disposal are reflected in the condensed consolidated statements of operations. Goodwill and Other Intangible Assets, net Goodwill represents the amount by which the purchase prices (including liabilities assumed) of acquired businesses exceed the estimated fair value of the net tangible assets and separately identifiable intangible assets of these businesses. Definite lived intangible assets, consisting primarily of trade names and technology, are amortized on a straight-line basis over the estimated useful life of the asset. Goodwill is not amortized but is tested at least annually for impairment. The Company reassesses the value of our reporting units and related goodwill balances annually on October 1 and at other times if events have occurred or circumstances exist that indicate the carrying amount of goodwill may not be recoverable. Recoverability of Long-Lived Assets and Intangible Assets The Company reviews its long-lived assets and definite lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If indicators of impairment exist, management identifies the asset group that includes the potentially impaired long-lived asset, at the lowest level at which there are separate, identifiable cash flows. If the fair value for the asset is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying amount of the asset. Mezzanine Equity The Company has issued various financial instruments, including preferred stock. Instruments containing redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control are classified as redeemable or mezzanine equity. The purpose of this classification is to convey that such a security may not be permanently part of equity and could result in a demand for cash, securities or other assets of the entity in the future. Warrants The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance, ASC 480 “Distinguishing Liabilities from Equity” and ASC 815, “Derivatives and Hedging.” Management’s assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, whether they meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815. For issued or modified warrants that do not meet all the criteria for equity classification, such warrants are required to be recorded as a liability initially at their fair value on the date of issuance, and subsequently remeasured to fair value on each balance sheet date thereafter. Changes in the estimated fair value of liability-classified warrants are recognized in other income (expense) in the condensed consolidated statements of operations in the period of change. Derivative Liabilities The Company evaluates its contracts to determine if those contracts qualify as derivatives under ASC 815. For derivative financial instruments that are accounted for as liabilities, including the Company’s contingent forward contract, the derivative instrument is initially recorded at its fair value and is then subsequently remeasured to fair value on each balance sheet date thereafter. Any changes in fair value are recorded in other income (expense) in the condensed consolidated statements of operations in the period of change. Revenue Recognition Revenue is recognized when there is a transfer of control of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services. The Company sells solar power systems under construction and development agreements to residential and commercial customers. The completed system is sold as a single performance obligation. For residential contracts, revenue is recognized at the point-in-time when the systems are placed into service. Any advance payments received in the form of customer deposits are recorded as contract liabilities. Commercial contracts are generally completed within three to twelve months from commencement of construction. Construction on large projects may be completed within eighteen to twenty-four months, depending on the size and location of the project. Revenues from commercial contracts are recognized under a percentage of completion method, measured by the percentage of hours incurred to date against estimated total hours budgeted for each contract. Because of inherent uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change within the near future. Contract costs include all direct material, labor costs and those indirect costs related to contract performance, such as indirect labor and other supplies. Selling, general and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and revenues which are recognized in the period in which the revisions are determined. Changes in estimated job profitability resulting from job performance, job conditions, contract penalty provisions, claims, change orders, and settlements, are accounted for as changes in estimates in the current period. Gross Excise Tax The State of Hawaii imposes a gross receipts tax on all business operations done in Hawaii. The Company records the tax revenue and expense on a gross basis. Cost of Sales Cost of sales consists of direct and indirect material and labor costs for solar energy system installations as well as warranty costs, permitting fees, financing fees and overhead, including costs related to procurement, warehousing and inventory management. Share-Based Compensation The Company accounts for share-based compensation awards on a fair value basis. The estimated grant date fair value of each stock-based award is recognized in the condensed consolidated statements of operations over the requisite service period (generally the vesting period). The Company recognizes forfeitures as they occur. Warranty SUNation NY offers product warranties for various periods against defects in material or installation workmanship. The manufacturers of the solar panels and the inverters provide a warranty period of generally 25 years and 10 years, respectively. SUNation NY will assist its customers in the event that the manufacturers' warranty needs to be used to replace a defective solar panel or inverter. SUNation NY provides for warranty up to the lifetime of the system on the installation of a system and all equipment and incidental supplies other than solar panels and inverters that are recovered under the manufacturers' warranty. SUNation NY provides extended workmanship warranties to the customer for up to 25 years for the service of inverters, which is reimbursed by the manufacturer. The Company estimates its warranty obligations upon installation, an expense included in cost of sales, based on management’s best estimate of the probable cost to be incurred in honoring its warranty commitment. Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. Our chief operating decision maker (“CODM”) is a committee comprised of our chief executive officer, chief operating officer and chief financial officer. Based on the financial information presented to and reviewed by our CODM in deciding how to allocate resources and in assessing performance, we have determined we have two operating and reportable segments. Net Loss Per Share Basic net loss attributable to common shareholders per common share is based on the weighted average number of common shares outstanding during each period. Diluted net loss attributable to common shareholders per common share adjusts for the dilutive effect of potential common shares outstanding. The Company had $264,482 and $11,587,121 in deemed dividends during the three and nine months ended September 30, 2024, which decreases the numerator in the net loss per share calculation. The Company’s only potential additional common shares outstanding are common shares that would result from the conversion of the convertible preferred shares, warrants, convertible debt and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three and nine months ended September 30, 2025 and September 30, 2024. The Company calculates the dilutive effect of outstanding warrants and unvested shares using the treasury stock method and the dilutive effect of outstanding preferred shares and convertible debt using the if-converted method. There were no options or deferred stock awards excluded from the calculation of diluted earnings per share because there were no outstanding options or deferred stock awards as of both September 30, 2025 and 2024. Restricted stock units totaling 5 and 4 would have been excluded from the calculation of diluted earnings per share for the nine months ended September 30, 2025 and 2024, respectively, even if there had not been a net loss in those periods, because the exercise price was greater than the average market price of common stock during the period. Accounting Standards Issued In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which is intended to clarify or improve disclosure and presentation requirements of a variety of topics. Many of the amendments will allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements and align the requirements in the FASB accounting standard codification with the SEC’s regulations. The amendments in ASU 2023-06 will become effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC, and will no longer be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. Early adoption is prohibited. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. This ASU is effective for fiscal periods beginning after December 15, 2024, with early adoption permitted. The Company discloses its income tax rate reconciliation in its annual financial statements only and does not expect the adoption of this ASU to have a material impact on its financial statements. 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”, which requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-04, “Debt with Conversion and Other Options,” which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This ASU is effective for annual periods beginning after December 15, 2025, and interim reporting periods within those annual report periods. Early adoption is permitted for all entities that have adopted the amendments in ASU Update 2020-06. Adoption can be on a prospective or retrospective basis. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements. In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”. ASU 2025-05 provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, “Revenue from Contracts with Customers”. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods in those years. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements.

Summary of Significant Accounting Policies

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned operating subsidiaries. Any reference in these notes to applicable guidance is meant to refer to the

authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2024 included on the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (“SEC”) on April 15, 2025. The accompanying condensed consolidated balance sheet at December 31, 2024 has been derived from the audited balance sheet at December 31, 2024 contained in the above-referenced Form 10-K. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and accounts have been eliminated.

Use of Estimates

The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company uses estimates based on the best information available in recording transactions and balances resulting from operations. Actual results could materially differ from those estimates. The Company’s estimates consist principally of allowances for credit losses, revenue recognition on commercial projects based on percentage of completion, asset impairment evaluations, accruals for compensation plans, lower of cost or net realizable value, inventory adjustments, fair value measurements, provisions for income taxes and deferred taxes, depreciable lives of fixed assets, and amortizable lives of intangible assets.

Cash, Restricted Cash and Cash Equivalents

For purposes of the condensed consolidated statements of cash flows, the Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. The Company may invest in short-term money market funds that are not considered to be bank deposits and are not insured or guaranteed by the federal deposit insurance company (“FDIC”) or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible to lose money investing in these funds. Total cash equivalents invested in short-term money market funds was $883,328 and $368,138 as of September 30, 2025 and December 31, 2024, respectively. The $288,948 of restricted cash and cash equivalents on the balance sheet as of September 30, 2025 are funds that can only be used to support the legacy Communications Systems, Inc. (“CSI”) business (which had merged with and into Pineapple Energy, Inc. in March 2022 (and Pineapple Energy, Inc.’s name was changed to SUNation Energy Inc. in November 2024, each as previously disclosed and described more fully in prior annual and quarterly reports)), and will be distributed to holders of the Company’s contingent value rights (“CVRs”) and cannot be used to support the working capital needs of the SUNation Energy business.

Accounts Receivable, Net

Accounts receivable are recorded at their net realizable value and are not collateralized. Accounts receivable include amounts earned less payments received and allowances for credit losses. Management continually monitors and adjusts its allowances associated with the Company’s receivables to address any credit risks associated with the accounts receivable and periodically writes off receivables when collection is not considered probable. The Company does not charge interest on past due accounts. When uncertainty exists as to the collection of receivables, the Company records an allowance for credit losses and a corresponding charge to credit loss expense.

Inventories, Net

Inventories, which consist primarily of materials and supplies used in the installation of solar systems, are stated at the lower of cost or net realizable value, with costs computed on a weighted average cost basis. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net realizable values when they are determined to be less than cost. The inventory reserve was $288,546 and $226,439 at September 30, 2025 and December 31, 2024, respectively.

Property, Plant and Equipment, net

Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method. Maintenance and repairs are charged to operations and additions or improvements are capitalized. Items of property sold, retired or otherwise disposed of are removed from the asset and accumulated depreciation accounts and any gains or losses on disposal are reflected in the condensed consolidated statements of operations.

Goodwill and Other Intangible Assets, net

Goodwill represents the amount by which the purchase prices (including liabilities assumed) of acquired businesses exceed the estimated fair value of the net tangible assets and separately identifiable intangible assets of these businesses. Definite lived intangible assets, consisting primarily of trade names and technology, are amortized on a straight-line basis over the estimated useful life of the asset. Goodwill is not amortized but is tested at least annually for impairment. The Company reassesses the value of our reporting units and related goodwill balances annually on October 1 and at other times if events have occurred or circumstances exist that indicate the carrying amount of goodwill may not be recoverable.

Recoverability of Long-Lived Assets and Intangible Assets

The Company reviews its long-lived assets and definite lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If indicators of impairment exist, management identifies the asset group that includes the potentially impaired long-lived asset, at the lowest level at which there are separate, identifiable cash flows. If the fair value for the asset is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying amount of the asset.

Mezzanine Equity

The Company has issued various financial instruments, including preferred stock. Instruments containing redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control are classified as redeemable or mezzanine equity. The purpose of this classification is to convey that such a security may not be permanently part of equity and could result in a demand for cash, securities or other assets of the entity in the future.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance, ASC 480 “Distinguishing Liabilities from Equity” and ASC 815, “Derivatives and Hedging.” Management’s assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, whether they meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815.

For issued or modified warrants that do not meet all the criteria for equity classification, such warrants are required to be recorded as a liability initially at their fair value on the date of issuance, and subsequently remeasured to fair value on each balance sheet date thereafter. Changes in the estimated fair value of liability-classified warrants are recognized in other income (expense) in the condensed consolidated statements of operations in the period of change.

Derivative Liabilities

The Company evaluates its contracts to determine if those contracts qualify as derivatives under ASC 815. For derivative financial instruments that are accounted for as liabilities, including the Company’s contingent forward contract, the derivative instrument is initially recorded at its fair value and is then subsequently remeasured to fair value on each balance sheet date thereafter. Any changes in fair value are recorded in other income (expense) in the condensed consolidated statements of operations in the period of change.

Revenue Recognition

Revenue is recognized when there is a transfer of control of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services. The Company sells solar power systems under construction and development agreements to residential and commercial customers. The completed system is sold as a single performance obligation. For residential contracts, revenue is recognized at the point-in-time when the systems are placed into service. Any advance payments received in the form of customer deposits are recorded as contract liabilities.

Commercial contracts are generally completed within three to twelve months from commencement of construction. Construction on large projects may be completed within eighteen to twenty-four months, depending on the size and location of the project. Revenues from commercial contracts are recognized under a percentage of completion method, measured by the percentage of hours incurred to date against estimated total hours budgeted for each contract. Because of inherent uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change within the near future. Contract costs include all direct material, labor costs and those indirect costs related to contract performance, such as indirect labor and other supplies. Selling, general and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and revenues which are recognized in the period in which the revisions are determined. Changes in estimated job profitability resulting from job performance, job conditions, contract penalty provisions, claims, change orders, and settlements, are accounted for as changes in estimates in the current period.

Gross Excise Tax

The State of Hawaii imposes a gross receipts tax on all business operations done in Hawaii. The Company records the tax revenue and expense on a gross basis.

Cost of Sales

Cost of sales consists of direct and indirect material and labor costs for solar energy system installations as well as warranty costs, permitting fees, financing fees and overhead, including costs related to procurement, warehousing and inventory management.

Share-Based Compensation

The Company accounts for share-based compensation awards on a fair value basis. The estimated grant date fair value of each stock-based award is recognized in the condensed consolidated statements of operations over the requisite service period (generally the vesting period). The Company recognizes forfeitures as they occur.

Warranty

SUNation NY offers product warranties for various periods against defects in material or installation workmanship. The manufacturers of the solar panels and the inverters provide a warranty period of generally 25 years and 10 years, respectively. SUNation NY will assist its customers in the event that the manufacturers' warranty needs to be used to replace a defective solar panel or inverter. SUNation NY provides for warranty up to the lifetime of the system on the installation of a system and all equipment and incidental supplies other than solar panels and inverters that are recovered

under the manufacturers' warranty. SUNation NY provides extended workmanship warranties to the customer for up to 25 years for the service of inverters, which is reimbursed by the manufacturer.

The Company estimates its warranty obligations upon installation, an expense included in cost of sales, based on management’s best estimate of the probable cost to be incurred in honoring its warranty commitment.

Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. Our chief operating decision maker (“CODM”) is a committee comprised of our chief executive officer, chief operating officer and chief financial officer. Based on the financial information presented to and reviewed by our CODM in deciding how to allocate resources and in assessing performance, we have determined we have two operating and reportable segments.

Net Loss Per Share

Basic net loss attributable to common shareholders per common share is based on the weighted average number of common shares outstanding during each period. Diluted net loss attributable to common shareholders per common share adjusts for the dilutive effect of potential common shares outstanding. The Company had $264,482 and $11,587,121 in deemed dividends during the three and nine months ended September 30, 2024, which decreases the numerator in the net loss per share calculation. The Company’s only potential additional common shares outstanding are common shares that would result from the conversion of the convertible preferred shares, warrants, convertible debt and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three and nine months ended September 30, 2025 and September 30, 2024. The Company calculates the dilutive effect of outstanding warrants and unvested shares using the treasury stock method and the dilutive effect of outstanding preferred shares and convertible debt using the if-converted method. There were no options or deferred stock awards excluded from the calculation of diluted earnings per share because there were no outstanding options or deferred stock awards as of both September 30, 2025 and 2024. Restricted stock units totaling 5 and 4 would have been excluded from the calculation of diluted earnings per share for the nine months ended September 30, 2025 and 2024, respectively, even if there had not been a net loss in those periods, because the exercise price was greater than the average market price of common stock during the period.

Accounting Standards Issued

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which is intended to clarify or improve disclosure and presentation requirements of a variety of topics. Many of the amendments will allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements and align the requirements in the FASB accounting standard codification with the SEC’s regulations. The amendments in ASU 2023-06 will become effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC, and will no longer be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. Early adoption is prohibited. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. This ASU is effective for fiscal periods beginning after December 15, 2024, with early adoption permitted. The Company discloses its income tax rate reconciliation in its annual financial statements only and does not expect the adoption of this ASU to have a material impact on its financial statements.

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”, which requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial

statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, “Debt with Conversion and Other Options,” which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This ASU is effective for annual periods beginning after December 15, 2025, and interim reporting periods within those annual report periods. Early adoption is permitted for all entities that have adopted the amendments in ASU Update 2020-06. Adoption can be on a prospective or retrospective basis. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”. ASU 2025-05 provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, “Revenue from Contracts with Customers”. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods in those years. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. The Company is currently evaluating this ASU and the impact it may have on its consolidated financial statements.

SUNation Energy, Inc. 10-Q
