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. 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, inventory obsolescence, allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates. Cash and Cash Equivalents Orion considers all highly liquid, short-term investments with original maturities of three months or less to be cash equivalents. Fair Value of Financial Instruments Orion’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other, revolving credit facility and long-term debt. In addition, other long-term assets includes an equity investment of $0.5 million that is carried at cost less impairment, of which there has been no impairment as of March 31, 2023. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: Level 1 — Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Valuations are based on quoted prices for similar assets or liabilities in active markets, or quoted prices in markets that are not active for which significant inputs are observable, either directly or indirectly. Level 3 — Valuations are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Inputs reflect management's best estimate of what market participants would use in valuing the asset or liability at the measurement date. The carrying amounts of Orion’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments. Long-term debt and revolving credit facility are classified as Level 2 in the fair value hierarchy because of the interest rates currently available to Orion for similar obligations. Allowance for Doubtful Accounts Orion performs ongoing evaluations of its customers and continuously monitors collections and payments. Orion estimates an allowance for doubtful accounts based upon the aging of the underlying receivables, historical experience with write-offs and specific customer collection issues that have been identified. See Note 4 – Accounts Receivable for further discussion of the allowance for doubtful accounts. Incentive Plan Orion’s compensation committee approved an Executive Annual Cash Incentive Program. Based upon the results for the fiscal years ended March 31, 2023, 2022, and 2021, Orion accrued approximately $0, $0.1 million, and $0.7 million expense related to this plan, respectively. Revenue Recognition Orion generates revenues primarily by selling commercial lighting fixtures and components, installing these fixtures in its customer’s facilities, and providing maintenance services including repairs and replacements for the lighting and related electrical components deployed in its customer’s facilities. Orion recognizes revenue in accordance with the guidance in “Revenue from Contracts with Customers” (Topic 606) (“ASC 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 that management expects to receive in exchange for those goods or services. Prices are generally fixed at the time of order confirmation, either for the contact as a whole or for the hourly rates that will be charged for the type of maintenance services delivered. The amount of expected consideration includes estimated deductions and early payment discounts calculated based on historical experience, customer rebates based on agreed upon terms applied to actual and projected sales levels over the rebate period, and any amounts paid to customers in conjunction with fulfilling a performance obligation. If there are multiple performance obligations in a single contract, the contract’s total transaction price is allocated to each individual performance obligation based on their relative standalone selling price. A performance obligation’s standalone selling price is the price at which Orion would sell such promised good or service separately to a customer. Orion uses an observable price to determine the stand-alone selling price for separate performance obligations or an expected cost-plus margin approach when one is not available. The expected cost-plus margin approach is used to determine the estimated stand-alone selling price for the installation performance obligation and is based on average historical installation margin. Revenue derived from customer contracts which include only performance obligation(s) for the sale of Orion manufactured or sourced lighting fixtures and components is classified as Product revenue in the Consolidated Statements of Operations. The revenue for these transactions is recorded at the point in time when management believes that the customer obtains control of the products, generally either upon shipment or upon delivery to the customer’s facility. This point in time is determined separately for each contract and requires judgment by management of the contract terms and the specific facts and circumstances concerning the transaction. Revenue from a customer contract which includes both the sale of Orion manufactured or sourced fixtures and the installation of such fixtures (which Orion refers to as a turnkey project) is allocated between each lighting fixture and the installation performance obligation based on relative standalone selling prices. Revenue from turnkey projects that is allocated to the sale of the lighting fixtures is recorded at the point in time when management believes the customer obtains control of the product(s) and is reflected in Product revenue. This point in time is determined separately for each customer contract based upon the terms of the contract and the nature and extent of Orion’s control of the light fixtures during the installation. Product revenue associated with turnkey projects can be recorded (a) upon shipment or delivery, (b) subsequent to shipment or delivery and upon customer payments for the light fixtures, (c) when an individual light fixture is installed and working correctly, or (d) when the customer acknowledges that the entire installation project is substantially complete. Determining the point in time when a customer obtains control of the lighting fixtures in a turnkey project can be a complex judgment and is applied separately for each individual light fixture included in a contract. In making this judgment, management considers the timing of various factors, including, but not limited to, those detailed below: • when there is a legal transfer of ownership; • when the customer obtains physical possession of the products; • when the customer starts to receive the benefit of the products; • the amount and duration of physical control that Orion maintains on the products after they are shipped to, and received at, the customer’s facility; • whether Orion is required to maintain insurance on the lighting fixtures when they are in transit and after they are delivered to the customer’s facility; • when each light fixture is physically installed and working correctly; • when the customer formally accepts the product; and • when Orion receives payment from the customer for the light fixtures. Revenue from turnkey projects that is allocated to the single installation performance obligation is reflected in Service revenue. Service revenue is recorded over-time as Orion fulfills its obligation to install the light fixtures. Orion measures its performance toward fulfilling its performance obligations for installations using an output method that calculates the number of light fixtures removed and installed as of the measurement date in comparison to the total number of light fixtures to be removed and installed under the contract. Revenue from the 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 Consolidated Statement of Operations. Orion offers a financing program, called an Orion Throughput Agreement, or OTA, for a customer’s lease of Orion’s energy management systems. The OTA is structured as a sales-type lease and upon successful installation of the system and customer acknowledgment that the system is operating as specified, revenue is recognized at Orion’s net investment in the lease, which typically is the net present value of the future cash flows. Orion also records revenue in conjunction with several limited power purchase agreements (“PPAs”) still outstanding. Those PPAs are supply-side agreements for the generation of electricity. Orion’s last PPA expires in 2031. Revenue associated with the sale of energy generated by the solar facilities under these PPAs is within the scope of ASC 606. Revenues are recognized over-time and are equal to the amount billed to the customer, which is calculated by applying the fixed rate designated in the PPAs to the variable amount of electricity generated each month. This approach is in accordance with the “right to invoice” practical expedient provided for in ASC 606. Orion also recognizes revenue upon the sale to third parties of tax credits received from operating the solar facilities and from amortizing a grant received from the federal government during the period starting when the power generating facilities were constructed until the expiration of the PPAs; these revenues are not derived from contracts with customers and therefore not under the scope of ASC 606. During the third quarter of fiscal 2023, Orion acquired Voltrek LLC ("Voltrek"), which sells and installs sourced electric vehicle charging stations and related software subscriptions and renewals. The results of Voltrek are included in the Orion EV segment and compliment Orion’s existing turnkey installation model. The sale of charging stations and related software subscriptions and renewals 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 and renewals, 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 Consolidated Statement of Operations. See Note 10 – Accrued Expenses and Other for a discussion of Orion’s accounting for the warranty it provides to customers for its products and services. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and Handling Costs Orion records costs incurred in connection with shipping and handling of products as cost of product revenue. Amounts billed to customers in connection with these costs are included in product revenue. Research and Development Orion expenses research and development costs as incurred. Amounts are included in the Statement of Operations on the line item Research and development. Income Taxes Orion recognizes deferred tax assets and liabilities for the future tax consequences of temporary differences between financial reporting and income tax basis of assets and liabilities, measured using the enacted tax rates and laws expected to be in effect when the temporary differences reverse. Deferred income taxes also arise from the future tax benefits of operating loss and tax credit carryforwards. A valuation allowance is established when management determines that it is more likely than not that all or a portion of a deferred tax asset will not be realized. For the fiscal year ended March 31, 2023, Orion recognized a valuation allowance for all of its net deferred tax assets. ASC 740, Income Taxes, also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination. Orion has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year. Orion recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are immaterial and are included in the unrecognized tax benefits. Stock Based Compensation Orion’s share-based payments to employees are measured at fair value and are recognized against earnings, on a straight-line basis over the requisite service period. Orion accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. Under the fair value recognition provisions of ASC 718, stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense ratably over the requisite service period. As more fully described in Note 17 – Stock Options and Restricted Shares, Orion currently awards non-vested restricted stock (and in some cases, in conjunction with associated cash award accounted for as a liability) to employees, executive officers and directors. Acquisition Related Costs Acquisition related costs includes legal fees, consulting and success fees, and other integration related costs. Concentration of Credit Risk and Other Risks and Uncertainties Orion’s cash is primarily deposited with one financial institution. At times, deposits in these institutions exceed 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 ballasts, lamps and LED components, from multiple suppliers. For fiscal 2023, 2022 and 2021, no supplier accounted for more than 10% of total cost of revenue. In fiscal 2023, one customer accounted for 16.2% of revenue. In fiscal 2022, one customer accounted for 49.1% of total revenue. In fiscal 2021, one customer accounted for 56.0% of total revenue. The revenue from this customer is recorded in Orion's OSG segment. As of March 31, 2023, one customer accounted for 10.8% of accounts receivable. As of March 31, 2022, two customers accounted for 11.8 % and 10.4 % of accounts receivable, respectively. Recent Accounting Pronouncements Issued: Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Since the issuance of ASU 2016-13, the FASB released several amendments to improve and clarify the implementation guidance. The provisions of ASU 2016-13 and the related amendments are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Orion does not anticipate the impact of adoption of this standard will be material on its consolidated statements of operations, cash flows, and the related footnote disclosures. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires an entity to use the guidance in ASC 606, Revenue from Contracts with Customers, rather than using fair value, when recognizing and measuring contract assets and contract liabilities related to customer contracts assumed in a business combination. The provisions of ASU 2021-08 are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Orion is currently evaluating the impact of adoption of this standard on its consolidated balance sheet.

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.

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, inventory obsolescence, allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates.

Cash and Cash Equivalents

Orion considers all highly liquid, short-term investments with original maturities of three months or less to be cash equivalents.

Fair Value of Financial Instruments

Orion’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other, revolving credit facility and long-term debt. In addition, other long-term assets includes an equity investment of $0.5 million that is carried at cost less impairment, of which there has been no impairment as of March 31, 2023. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 — Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations are based on quoted prices for similar assets or liabilities in active markets, or quoted prices in markets that are not active for which significant inputs are observable, either directly or indirectly.

Level 3 — Valuations are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Inputs reflect management's best estimate of what market participants would use in valuing the asset or liability at the measurement date.

The carrying amounts of Orion’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments. Long-term debt and revolving credit facility are classified as Level 2 in the fair value hierarchy because of the interest rates currently available to Orion for similar obligations.

Allowance for Doubtful Accounts

Orion performs ongoing evaluations of its customers and continuously monitors collections and payments. Orion estimates an allowance for doubtful accounts based upon the aging of the underlying receivables, historical experience with write-offs and specific customer collection issues that have been identified. See Note 4 – Accounts Receivable for further discussion of the allowance for doubtful accounts.

Incentive Plan

Orion’s compensation committee approved an Executive Annual Cash Incentive Program. Based upon the results for the fiscal years ended March 31, 2023, 2022, and 2021, Orion accrued approximately $0, $0.1 million, and $0.7 million expense related to this plan, respectively.

Revenue Recognition

Orion generates revenues primarily by selling commercial lighting fixtures and components, installing these fixtures in its customer’s facilities, and providing maintenance services including repairs and replacements for the lighting and related electrical components deployed in its customer’s facilities. Orion recognizes revenue in accordance with the guidance in “Revenue from Contracts with Customers” (Topic 606) (“ASC 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 that management expects to receive in exchange for those goods or services. Prices are generally fixed at the time of order confirmation, either for the contact as a whole or for the hourly rates that will be charged for the type of maintenance services delivered. The amount of expected consideration includes estimated deductions and early payment discounts calculated based on historical experience, customer rebates based on agreed upon terms applied to actual and projected sales levels over the rebate period, and any amounts paid to customers in conjunction with fulfilling a performance obligation.

If there are multiple performance obligations in a single contract, the contract’s total transaction price is allocated to each individual performance obligation based on their relative standalone selling price. A performance obligation’s standalone selling price is the price at which Orion would sell such promised good or service separately to a customer. Orion uses an observable price to determine the stand-alone selling price for separate performance obligations or an expected cost-plus margin approach when one is not available. The expected cost-plus margin approach is used to determine the estimated stand-alone selling price for the installation performance obligation and is based on average historical installation margin.

Revenue derived from customer contracts which include only performance obligation(s) for the sale of Orion manufactured or sourced lighting fixtures and components is classified as Product revenue in the Consolidated Statements of Operations. The revenue for these transactions is recorded at the point in time when management believes that the customer obtains control of the products, generally either upon shipment or upon delivery to the customer’s facility. This point in time is determined separately for each contract and requires judgment by management of the contract terms and the specific facts and circumstances concerning the transaction.

Revenue from a customer contract which includes both the sale of Orion manufactured or sourced fixtures and the installation of such fixtures (which Orion refers to as a turnkey project) is allocated between each lighting fixture and the installation performance obligation based on relative standalone selling prices.

Revenue from turnkey projects that is allocated to the sale of the lighting fixtures is recorded at the point in time when management believes the customer obtains control of the product(s) and is reflected in Product revenue. This point in time is determined separately for each customer contract based upon the terms of the contract and the nature and extent of Orion’s control of the light fixtures during the installation. Product revenue associated with turnkey projects can be recorded (a) upon shipment or delivery, (b) subsequent to shipment or delivery and upon customer payments for the light fixtures, (c) when an individual light fixture is installed and working correctly, or (d) when the customer acknowledges that the entire installation project is substantially complete. Determining the point in time when a customer obtains control of the lighting fixtures in a turnkey project can be a complex judgment and is applied separately for each individual light fixture included in a contract. In making this judgment, management considers the timing of various factors, including, but not limited to, those detailed below:

•

when there is a legal transfer of ownership;

•

when the customer obtains physical possession of the products;

•

when the customer starts to receive the benefit of the products;

•

the amount and duration of physical control that Orion maintains on the products after they are shipped to, and received at, the customer’s facility;

•

whether Orion is required to maintain insurance on the lighting fixtures when they are in transit and after they are delivered to the customer’s facility;

•

when each light fixture is physically installed and working correctly;

•

when the customer formally accepts the product; and

•

when Orion receives payment from the customer for the light fixtures.

Revenue from turnkey projects that is allocated to the single installation performance obligation is reflected in Service revenue. Service revenue is recorded over-time as Orion fulfills its obligation to install the light fixtures. Orion measures its performance toward fulfilling its performance obligations for installations using an output method that calculates the number of light fixtures removed and installed as of the measurement date in comparison to the total number of light fixtures to be removed and installed under the contract.

Recent Accounting Pronouncements

Issued: Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Since the issuance of ASU 2016-13, the FASB released several amendments to improve and clarify the implementation guidance. The provisions of ASU 2016-13 and the related amendments are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Orion does not anticipate the impact of adoption of this standard will be material on its consolidated statements of operations, cash flows, and the related footnote disclosures.

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires an entity to use the guidance in ASC 606, Revenue from Contracts with Customers, rather than using fair value, when recognizing and measuring contract assets and contract liabilities related to customer contracts assumed in a business combination. The provisions of ASU 2021-08 are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Orion is currently evaluating the impact of adoption of this standard on its consolidated balance sheet.
