Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of Orion Energy Systems, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Orion have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement have been included. Interim results are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2025 or other interim periods. The Condensed Consolidated Balance Sheet as of March 31, 2024 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in Orion’s Annual Report on Form 10-K for the fiscal year ended March 31, 2024 filed with the SEC on June 12, 2024. Allowance for Credit Losses Orion performs ongoing evaluations of its customers and continuously monitors collections and payments. Orion estimates an allowance for credit losses based upon the historical collectability based on past due status and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. We also consider customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, net realizable value of inventory, allowance for credit losses, accruals for warranty and loss contingencies, earn-out, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates. Concentration of Credit Risk and Other Risks and Uncertainties Orion's cash is primarily deposited with one financial institution. At times, deposits in this institution exceeds the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including lamps and LED components, from multiple suppliers. For the three and six months ended September 30, 2024 and 2023, no suppliers accounted for more than 10 % of total cost of revenue. For the three months ended September 30, 2024, two customers accounted for 25.0 % and 12.5% of total revenue, respectively. For the six months ended September 30, 2024, two customers accounted for 23.0 % and 10.4% of total revenue, respectively. For the three months ended September 30, 2023, two customers accounted for 18.2 % and 10.7 % of total revenue, respectively. For the six months ended September 30, 2023, two customers accounted for 19.3 % and 10.8 % of total revenue, respectively. As of September 30, 2024 , one customer accounted for 21.7 % and one customer accounted for 17.9 % of accounts receivable. As of March 31, 2024 , two customers accounted for 17.3 % and 11.7 % of accounts receivable, respectively. Recent Accounting Pronouncements Issued: Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which modifies the disclosure and presentation requirements of reportable segments. The amendments in the update require the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (the "CODM") and included within each reported measure of segment profit and loss. The amendments also require disclosure of all other segment items by reportable segment and a description of its composition. Additionally, the amendments require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This update is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Orion is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity's income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. The update will be effective for annual periods beginning after December 15, 2025. Orion is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes.

REVENUE

REVENUE	6 Months Ended

Revenue from Contract with Customer [Abstract]
REVENUE	NOTE 3 — REVENU E Orion generates revenue primarily by selling manufactured or sourced commercial lighting fixtures and components, sourced electric vehicle chargers and related products, installing these products in customer’s facilities, and providing maintenance services including repairs and replacements for the lighting and related electrical components. Orion recognizes revenue in accordance with the guidance in “Revenue from Contracts with Customers” (Topic 606) when control of the goods or services being provided (which Orion refers to as a performance obligation) is transferred to a customer at an amount that reflects the consideration Orion expects to receive in exchange for those goods or services. The sale of charging stations and related software subscriptions, renewals and extended warranty is presented in Product revenue. Orion is the principal in the sales of charging stations as it has control of the physical products prior to transfer to the customer. Accordingly, revenue is recognized on a gross basis. For certain sales, primarily software subscriptions, renewals and extended warranty, Orion is the sales agent providing access to the content and recognize commission revenue net of amounts due to third parties who fulfill the performance obligation. For these sales, control passes at the point in time upon providing access of the content to the customer. The sale of installation and services related to the EV charging business is presented in Service revenue. Revenue from the EV segment that includes both the sale of product and service is allocated between the product and service performance obligations based on relative standalone selling prices, and is recorded in Product revenue and Service revenue, respectively, in the Condensed Consolidated Statement of Operations. Revenue from the lighting maintenance offering that includes both the sale of Orion manufactured or sourced product and service is allocated between the product and service performance obligations based on relative standalone selling prices, and is recorded in Product revenue and Service revenue, respectively, in the Condensed Consolidated Statement of Operations. The following tables provide detail of Orion’s total revenue for the three and six months ended September 30, 2024 and September 30, 2023 (dollars in thousands): Three Months Ended September 30, 2024 Six Months Ended September 30, 2024 Product Services Total Product Services Total Revenue from contracts with customers: Lighting product and installation $ 9,301 $ 1,297 $ 10,598 $ 19,345 $ 3,971 $ 23,316 Maintenance services 1,123 2,674 3,797 2,123 4,997 7,120 Electric vehicle charging 1,702 3,023 4,725 3,391 5,165 8,556 Solar energy related revenues 2 — 2 17 — 17 Total revenues from contracts with customers 12,128 6,994 19,122 24,876 14,133 39,009 Revenue accounted for under other guidance 239 — 239 258 — 258 Total revenue $ 12,367 $ 6,994 $ 19,361 $ 25,134 $ 14,133 $ 39,267 Three Months Ended September 30, 2023 Six Months Ended September 30, 2023 Product Services Total Product Services Total Revenue from contracts with customers: Lighting product and installation $ 11,928 $ 1,614 $ 13,542 $ 23,713 $ 2,445 $ 26,158 Maintenance services 876 2,757 3,633 1,775 5,612 7,387 Electric vehicle charging 2,752 627 3,379 3,734 883 4,617 Solar energy related revenues 13 — 13 13 — 13 Total revenues from contracts with customers 15,569 4,998 20,567 29,235 8,940 38,175 Revenue accounted for under other guidance 19 — 19 24 — 24 Total revenue $ 15,588 $ 4,998 $ 20,586 $ 29,259 $ 8,940 $ 38,199 From time to time, Orion sells the receivables from one customer to a financing institution. The total amount received from the advances of these receivables was $0.6 million for the three and six months ended September 30, 2024. Orion's losses on these sales were $18 thousand for the three and six months ended September 30, 2024, and are included in Interest expense in the Condensed Consolidated Statement of Operations. There was no activity during the three and six months ended September 30, 2023. The following chart shows the balance of Orion’s receivables arising from contracts with customers, contract assets and contract liabilities as of September 30, 2024 and March 31, 2024 (dollars in thousands): September 30, March 31, Accounts receivable, net $ 11,709 $ 14,022 Revenue earned but not billed (1) $ 5,709 $ 4,539 Deferred revenue (2) $ 241 $ 124 (1) $0.2 million of our revenue earned but not billed is accounted for as a sales type lease under ASC 842, and therefore not considered a "contract asset", which is an asset defined by ASC 606. (2) Includes the unamortized portion of the funds received from the federal government in 2010 and 2011 as reimbursement for the costs to build the two facilities related to the PPAs. As the transaction is not considered a contract with a customer, this value is not a contract liability as defined by ASC 606. There were no significant changes in the contract assets outside of standard increases which are partially offset by reclassifications to accounts receivable, net upon billing. Deferred revenue, current as of September 30, 2024 and March 31, 2024, includes $ 0.2 million and $ 0.1 million, respectively, of contract liabilities which represent consideration received from a new customer contract on which installation has not yet begun and Orion has not fulfilled the promises included. Of the $0.1 million outstanding as of March 31, 2024, $0.1 million has been recognized as revenue.

Leases [Abstract]
LEASES	NOTE 8 — LEASES From time to time, Orion leases assets from third parties. Orion also leases certain assets to third parties. Orion accounts for leases in accordance with Accounting Standards Codification ("ASC") 842. Under ASC 842, both finance and operating lease ROU assets and lease liabilities for leases with initial terms in excess of 12 months are recognized at the commencement date based on the present value of lease payments over the lease term. Orion recognizes lease expense for leases with an initial term of 12 months or less, referred to as short term leases, on a straight-line basis over the lease term. A summary of Orion’s assets leased from third parties follows (dollars in thousands): Balance sheet classification September 30, 2024 March 31, 2024 Assets Operating lease assets Other long-term assets $ 1,165 $ 1,770 Liabilities Current liabilities Operating lease liabilities Accrued expenses and other $ 946 $ 990 Non-current liabilities Operating lease liabilities Other long-term liabilities 478 1,121 Total lease liabilities $ 1,424 $ 2,111 Orion had operating lease costs of $ 0.3 million and $ 0.7 million for the three and six months ended September 30, 2024 , respectively. Orion had operating lease costs of $ 0.7 million and $ 1.1 million for the three and six months ended September 30, 2023, respectively. The estimated maturity of lease liabilities for each of the remaining years is shown below (dollars in thousands): Maturity of Lease Liabilities Operating Leases Fiscal 2025 (period remaining) $ 498 Fiscal 2026 889 Fiscal 2027 106 Thereafter — Total lease payments $ 1,493 Less: Interest ( 69 ) Present value of lease liabilities $ 1,424 Assets Orion Leases to Other Parties Orion provides long-term financing to one customer who frequently engages Orion in large turnkey projects that span between three and nine months. The customer executes an agreement providing for monthly payments, at a fixed monthly amount, of the contract price, plus interest, over typically a five-year period. The total transaction price in these contracts is allocated between product and services in the same manner as all other turnkey projects. The portion of the transaction associated with the installation is accounted for consistently with all other installation related performance obligations under ASC 606. While Orion retains ownership of the light fixtures during the financing period, the transaction terms and the underlying economics associated with used lighting fixtures results in Orion essentially ceding ownership of the lighting fixtures to the customer after completion of the agreement. Therefore, the portions of the transaction associated with the sale of the multiple individual light fixtures is accounted for as a sales-type lease under ASC 842. Revenues, and production and acquisition costs, associated with sales-type leases are included in Product revenue and Cost of product revenue in the Consolidated Statement of Operations. These amounts are recorded for each fixture separately based on the customer’s monthly acknowledgment that specified fixtures have been installed and are operating as specified. The execution of the acknowledgment is considered the commencement date as defined in ASC 842. The following chart shows the amount of revenue and cost of sales arising from sales-type leases during the quarter ended September 30, 2024 and 2023 (dollars in thousands): Three Months Ended September 30, Six Months Ended September 30, 2024 2023 2024 2023 Product revenue $ 209 $ — $ 209 $ — Cost of product revenue $ 195 $ — $ 195 $ —

Earnings Per Share [Abstract]
NET LOSS INCOME PER COMMON SHARE	NOTE 11 — NET LOSS PER COMMON SHARE Basic net loss per common share is computed by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding for the period and does not consider common stock equivalents. Diluted net loss per common share reflects the dilution that would occur if restricted shares were vested. In the computation of diluted net loss per common share, Orion uses the treasury stock method for outstanding options and restricted shares. For the three and six months ended September 30, 2024 and 2023, Orion was in a net loss position; therefore, the Basic and Diluted weighted-average shares outstanding are equal because any increase to the basic shares would be anti-dilutive. Net loss per common share is calculated based upon the following shares: For the Three Months Ended For the Six Months Ended 2024 2023 2024 2023 Numerator: Net loss (in thousands) $ ( 3,625 ) $ ( 4,388 ) $ ( 7,383 ) $ ( 11,025 ) Denominator: Weighted-average common shares outstanding 32,825,477 32,502,566 32,718,628 32,424,623 Weighted-average common shares and common share 32,825,477 32,502,566 32,718,628 32,424,623 Net loss per common share: Basic $ ( 0.11 ) $ ( 0.14 ) $ ( 0.23 ) $ ( 0.34 ) Diluted $ ( 0.11 ) $ ( 0.14 ) $ ( 0.23 ) $ ( 0.34 ) The following table indicates the number of potentially dilutive securities excluded from the calculation of Diluted net loss per common share because their inclusion would have been anti-dilutive.

The Credit Agreement provides for a five-year $ 25.0 million revolving credit facility (the “Credit Facility”) that matures on December 29, 2025. Borrowings under the Credit Facility are subject to a borrowing base requirement based on eligible receivables, inventory and cash. As of September 30, 2024, the borrowing base of the Credit Facility supported approximately $ 16.7 million of availability, with $ 7.7 million of remaining availability net of $ 9.0 million borrowed. Effective November 4, 2022, Orion, with Bank of America, N.A. as lender, executed Amendment No. 1 to its Credit Agreement. The primary purpose of the amendment was to include the assets of the acquired subsidiaries, Stay-Lite Lighting, Inc. ("Stay-Lite Lighting") and Voltrek, as secured collateral under the Credit Agreement. Accordingly, eligible assets of Stay-Lite and Voltrek will be included in the borrowing base calculation for the purpose of establishing the monthly borrowing availability under the Credit Agreement. The amendment also clarified that the earn-out liabilities associated with the Stay-Lite and Voltrek transactions are permitted under the Credit Agreement and that the expenses recognized in connection with those earn-outs should be added back in the computation of EBITDA, as defined, under the Credit Agreement. Effective April 22, 2024, the Company, with Bank of America, N.A. as lender, executed Amendment No. 2 to its Credit Agreement (“Amendment No. 2”). The primary purpose of Amendment No. 2 was to add a $ 3.525 million mortgage loan facility to the Credit Agreement secured by the Company’s office headquarters property in Manitowoc, Wisconsin. Amendment No. 2 also broadened the definition of receivables to encompass government receivables as being eligible to be included in the Company’s borrowing base calculation for the purpose of establishing the Company’s monthly borrowing availability under the Credit Agreement. Quarterly installments of $ 88,125 are due on the first day of each fiscal quarter beginning October 1, 2024. Remaining principal payments on long-term debt are $ 0.2 million and $3.3 million in fiscal 2025 and fiscal 2026, respectively. An additional $9.0 million is due in fiscal 2026, which is related to the Credit Facility. As discussed in Note 19 - Subsequent Events, the maturity date of the Credit Facility was extended from December 29, 2025 to June 30, 2027. As of September 30, 2024 , Orion was in compliance with all debt covenants.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 13 — INCOME TAXES Orion’s income tax provision was determined by applying an estimated annual effective tax rate, based upon the facts and circumstances known, to book income (loss) before income tax, adjusting for discrete items. Orion’s actual effective tax rate is adjusted each interim period, as appropriate, for changes in facts and circumstances. For the three months ended September 30, 2024 and 2023, Orion recorded income tax expense of $ 23 thousand and $ 15 thousand, respectively, using this methodology. For the six months ended September 30, 2024 and 2023, Orion recorded income tax expense of $ 44 thousand and $ 57 thousand, respectively, using this methodology. As of September 30, 2024 and March 31, 2024, Orion had a full valuation allowance against its net deferred tax asset balance. Orion considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that Orion determines that the deferred tax assets are able to be realized, an adjustment to the deferred tax asset would increase income in the period such determination is made. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Orion considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that Orion determines that the more or less of its deferred tax assets are able to be realized, an adjustment to the valuation allowance would be reflected in the company’s provision for income taxes. Uncertain Tax Positions As of September 30, 2024, Orion’s balance of gross unrecognized tax benefits was approximat ely $ 0.2 million, all of which would reduce Orion’s effective tax rate if recognized. Orion has classified the amounts recorded for uncertain tax benefits in the balance sheet as Other long-term liabilities to the extent that payment is not anticipated within one year. Orion recognizes penalties and interest related to uncertain tax liabilities in income tax (benefit) expense. Penalties and interest are included in the unrecognized tax benefits.

Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Orion have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement have been included. Interim results are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2025 or other interim periods. The Condensed Consolidated Balance Sheet as of March 31, 2024 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in Orion’s Annual Report on Form 10-K for the fiscal year ended March 31, 2024 filed with the SEC on June 12, 2024.
Allowance for Credit Losses	Allowance for Credit Losses Orion performs ongoing evaluations of its customers and continuously monitors collections and payments. Orion estimates an allowance for credit losses based upon the historical collectability based on past due status and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. We also consider customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, net realizable value of inventory, allowance for credit losses, accruals for warranty and loss contingencies, earn-out, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates.
Concentration of Credit Risk and Other Risks and Uncertainties	Concentration of Credit Risk and Other Risks and Uncertainties Orion's cash is primarily deposited with one financial institution. At times, deposits in this institution exceeds the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including lamps and LED components, from multiple suppliers. For the three and six months ended September 30, 2024 and 2023, no suppliers accounted for more than 10 % of total cost of revenue. For the three months ended September 30, 2024, two customers accounted for 25.0 % and 12.5% of total revenue, respectively. For the six months ended September 30, 2024, two customers accounted for 23.0 % and 10.4% of total revenue, respectively. For the three months ended September 30, 2023, two customers accounted for 18.2 % and 10.7 % of total revenue, respectively. For the six months ended September 30, 2023, two customers accounted for 19.3 % and 10.8 % of total revenue, respectively. As of September 30, 2024 , one customer accounted for 21.7 % and one customer accounted for 17.9 % of accounts receivable. As of March 31, 2024 , two customers accounted for 17.3 % and 11.7 % of accounts receivable, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued: Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which modifies the disclosure and presentation requirements of reportable segments. The amendments in the update require the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (the "CODM") and included within each reported measure of segment profit and loss. The amendments also require disclosure of all other segment items by reportable segment and a description of its composition. Additionally, the amendments require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This update is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Orion is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity's income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. The update will be effective for annual periods beginning after December 15, 2025. Orion is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes.
