Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of DLH Holdings Corp. and its wholly-owned subsidiaries (together with its subsidiaries, "DLH" or the "Company" and also referred to as "we," "us" and "our"). All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying financial statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these statements do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the nine months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending September 30, 2024 or any future period. Amounts as of June 30, 2024 and for the three and nine months ended June 30, 2024 are unaudited. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2023 filed with the Securities and Exchange Commission on December 6, 2023.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies 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, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The most significant of these estimates and assumptions relate to estimating costs including overhead and its allocation, valuing and determining the amortization periods for long-lived intangible assets, interest rate swaps, stock-based compensation, and right-of-use assets and lease liabilities. We evaluate these estimates and judgments on an ongoing basis and base our estimates on historical experience, current and expected future outcomes, third-party evaluations, and various other assumptions that we believe are reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. We revise material accounting estimates if changes occur, such as more experience is acquired, additional information is obtained, or there is new information on which an estimate was or can be based. Actual results could differ from those estimates. Revenue The Company's revenues from contracts with customers are derived from offerings that include technology-enabled business process outsourcing, program management solutions, and public health research and analytics, substantially within the U.S. government and its agencies. The Company has various types of contracts including time-and-materials contracts, cost-reimbursable contracts, and firm-fixed-price contracts. We consider a contract with a customer to exist when there is a commitment by both parties (customer and Company), payment terms are determinable, there is commercial substance, and collectability is probably in accordance with Accounting Standards Codification ("ASC") No. 606, "Revenue from Contracts with Customers" ("Topic 606"). We recognize revenue over time when there is a continuous transfer of control to our customer as performance obligations are satisfied. For our U.S. government contracts, this continuous transfer of control to the customer is transferred over time and revenue is recognized based on the extent of progress toward completion of the performance obligation. We consider control to transfer when we have a right to payment. In some instances, the Company commences providing services prior to formal approval to begin work from the customer. The Company considers these factors, the risks associated with commencing work, and legal enforceability in determining whether a contract exists under Topic 606. Contract modification can occur throughout the life of the contract and can affect the transaction price, extend the period of performance, adjust funding, or create new performance obligations. We review each modification to assess the impact of these contract changes to determine if it should be treated as part of the original performance obligation or as a separate contract. Contract modifications impact performance obligations when the modification either creates new or changes the existing enforceable rights and obligations. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue and profit cumulatively. Furthermore, a significant change in one or more estimates could affect the profitability of our contracts. We recognize adjustments in estimated profit on contracts in the period identified. For service contracts, we satisfy our performance obligations as services are rendered. We use cost-based input and time-based output methods to measure progress based on the contract type. • Time and material - We bill the customer per labor hour and per material, and revenue is recognized in the amount invoiced as the amount corresponds directly to the value of our performance to date. Revenue is recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred. • Cost reimbursable - We record reimbursable costs as incurred, including an estimated share of the contractual fee earned. • Firm fixed price - We recognize revenue over time using a straight-line measure of progress. Contract costs generally include direct costs such as labor, materials, subcontract costs, and indirect costs identifiable with or allocable to a specific contract. Costs are expensed as incurred and include an estimate of the contractual fees earned. Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by various government audit agencies. Historically, our adjustments have not been material. Contract assets - Amounts are invoiced as work progresses in accordance with agreed-upon contractual terms. In part, revenue recognition occurs before we have the right to bill, resulting in contract assets. These contract assets are reported within accounts receivable on our consolidated balance sheets and are invoiced in accordance with payment terms defined in each contract. Period end balances will vary from period to period due to agreed-upon contractual terms. Fair Value of Financial Instruments The carrying amounts of the Company's cash, accounts receivable, contract assets, accrued expenses, and accounts payable approximate fair value due to the short-term nature of these instruments. The fair values of the Company's debt instruments approximate fair value because the underlying interest rates approximate market rates that the Company could obtain for similar instruments at the balance sheet dates. Long-Lived Assets Our long-lived assets include equipment and improvements, intangible assets, right-of-use assets, and goodwill. The Company continues to review long-lived assets for possible impairment or loss of value at least annually, or more frequently upon the occurrence of an event or when circumstances indicate that a reporting unit's carrying amount is greater than its fair value. Equipment and improvements are recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful asset lives (3 to 7 years) and the shorter of the initial lease term or estimated useful life for leasehold improvements. Maintenance and repair costs are expensed as incurred. Intangible assets (other than goodwill) are originally recorded at fair value and are amortized on a straight-line basis over their estimated useful lives of 10 years. Right-of-use assets are measured at the present value of future minimum lease payments, including all probable renewals, plus lease payments made to the lessor before or at lease commencement and indirect costs paid, less incentives received. Our right-of-use assets include long-term leases for facilities and equipment and are amortized over their respective lease terms. Lease Liabilities The Company has leases for facilities and office equipment. Our lease liabilities are recognized as the present value of the future minimum lease payments over the lease term. Our lease payments consist of fixed and in-substance fixed amounts attributable to the use of the underlying asset over the lease term. Variable lease payments that do not depend on an index rate or are not in-substance fixed payments are excluded in the measurement of right-of-use assets and lease liabilities and are expensed in the period incurred. The incremental borrowing rate on our secured term loan is used in determining the present value of future minimum lease payments. Some of our lease agreements include options to extend the lease term or terminate the lease. These options are accounted for in our right-of-use assets and lease liabilities when it is reasonably certain that the Company will extend the lease term or terminate the lease. The Company does not have any finance leases. Goodwill The Company reviews goodwill for impairment on an annual basis and on a quarterly basis the Company assesses the impact of any macroeconomic changes that may impact the business conditions to determine if these changes have any adverse impact to goodwill. Notwithstanding this evaluation, factors including non-renewal of a major contract or other substantial changes in business conditions could have a material adverse effect on the valuation of goodwill in future periods and the resulting charge could be material to future periods’ results of operations. The Company determined that no change in business conditions occurred which would have a material adverse effect on the valuation of goodwill. Income Tax The Company accounts for income taxes in accordance with the asset and liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reflected on the consolidated balance sheets when it is determined that it is more likely than not that the asset will be realized. This guidance also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. We account for uncertain tax positions by recognizing the financial statement effects of a tax position only when, based upon the technical merits, it is more likely than not that the position will be sustained upon examination. We had no uncertain tax positions at either June 30, 2024 or September 30, 2023. We report interest and penalties as a component of provision for income taxes. During the three and nine months ended June 30, 2024 and 2023, we recognized no interest and no penalties related to income taxes. Stock-Based Compensation The Company uses the fair value-based method for stock-based compensation. Options issued are designated as either an incentive stock option or a non-statutory stock option. No option may be granted with a term of more than 10 years from the date of grant. Option awards may depend on achievement of certain performance measures determined by the Compensation Committee of our Board. Shares issued upon option exercise are newly issued common shares. All awards t o employees and non- employee s are reco rded at fair value on the date of the grant and expensed over the period of vesting. The Company uses a Monte Carlo method to estimate the fair value of each stock option at the date of grant. Any consideration paid by the option holders to purchase shares is credited to common stock. Stock-based compensation expense for the portion of equity awards for which the requisite service has not been rendered is recognized as the requisite service is rendered. The stock-based compensation expense for that portion of awards has been based on the grant-date fair value of those awards as calculated for recognition purposes under applicable guidance. For options that vest based on the Company’s common stock achieving and maintaining defined market prices, the Company values the awards with a Monte Carlo method that utilizes various probability factors and other criterion in establishing fair value of the grant. The related compensation expense is recognized over the service period. Cash The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. We maintain cash balances at financial institutions that are insured by the Federal Deposit Insurance Corporation up to $250,000. Deposits held with financial institutions may exceed the $250,000 limit. Accounts Receivable Receivables include amounts billed and currently due from customers where the right to consideration is unconditional and amounts unbilled. Both billed and unbilled amounts are non-interest bearing, unsecured, and recognized at an estimated realizable value that includes costs and fees, and are generally expected to be billed and received within a single year. We evaluate our receivables for expected credit losses on a quarterly basis and determine whether an allowance for expected credit losses is appropriate based on specific collection issues. Earnings Per Share Basic earnings per share is calculated by dividing income available to common shareholders by the weighted average number of common stock outstanding and restricted stock grants that vested or are likely to vest during the period. Diluted earnings per share is calculated by dividing income available to common shareholders by the weighted average number of basic common shares outstanding, adjusted to reflect potentially dilutive securities. Diluted earnings per share is calculated using the treasury stock method. Treasury Stock The Company periodically purchases its own common stock that is traded on public markets as part of announced stock repurchase programs. The repurchased common stock is classified as treasury stock on the consolidated balance sheets and held at cost. As of June 30, 2024 and September 30, 2023, the Company did not hold any treasury stock. Preferred Stock Our certificate of incorporation authorizes the issuance of "blank check" preferred stock with designations, rights and preferences as may be determined from time to time by our board of directors up to an aggregate of 5,000,000 shares of preferred stock. As of June 30, 2024 and September 30, 2023, the Company has not issued any preferred stock. Interest Rate Swap The Company uses derivative financial instruments to manage interest rate risk associated with its variable debt. The Company's objective in using these interest rate derivatives is to manage its exposure to interest rate movements and reduce volatility of interest expense. The gains and losses due to changes in the fair value of the interest rate swap agreements completely offset changes in the fair value of the hedged portion of the underlying debt. Offsetting changes in fair value of both the interest rate swaps and the hedged portion of the underlying debt are recognized in interest expense in the consolidated statements of operations. The Company does not hold or issue any derivative instruments for trading or speculative purposes. Risks and Uncertainties Management evaluates the impact of global markets and economic factors on our industry and the potential for adverse effects on the Company's consolidated financial position and its operations. As of June 30, 2024 and September 30, 2023 there was no indication of any global or economic impacts to our industry.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In November 2023, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which provides guidance intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, and each reported measure of segment profit or loss. The ASU requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this ASU and all existing segment disclosures in Topic 280. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2023 and interim periods beginning after December 15, 2024. We are currently evaluating the impacts of the single reportable segment disclosures. In December 2023, FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" which provides guidance on the requirements such as the requirement that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. DLH is a public company that reports income tax disclosures and therefore this ASU applies to the Company. ASU 2023-09 is effective for public business entities for fiscal years beginning after Dec. 15, 2024. We are currently evaluating the impacts of the improvements to income tax disclosure. In March 2024, FASB issued ASU No. 2024-01, "Scope Application of Profits Interest and Similar Awards". The ASU clarifies how an entity determines whether a profits interest or similar award is (1) within the scope of ASC 718 or (2) not a share-based payment arrangement and therefore within the scope of other guidance. The guidance in ASU 2024-01 applies to all entities that issue profits interest awards as compensation to employees or non-employees in exchange for goods or services. We are currently evaluating the impacts of the improvements to our disclosure. In March 2024, the Securities and Exchange Commission ("SEC") has released a final rule that requires registrants to provide comprehensive climate-related disclosures in their annual reports and registration statements, including those for IPOs, beginning with annual reports for the year ending December 31, 2027, for smaller reporting companies ("SRC"). Registrants must disclose climate-related financial metrics and impacts on their financial estimates and assumptions in a footnote to the audited financial statements. The disclosures will also need to be addressed as part of management’s internal control over financial reporting ("ICFR") and will be subject to the financial statement and ICFR audit (if applicable) of an independent registered public accounting firm. We are currently evaluating the impacts of the improvements to our disclosure.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The following table summarizes the contract balances recognized on the Company's consolidated balance sheets as follows (in thousands): June 30, September 30, 2024 2023 Contract assets $ 23,061 $ 20,542 Contract assets are included as part of the accounts receivable on the consolidated balances sheets. Contract liabilities had no balance as of June 30, 2024 and September 30, 2023. Disaggregation of Revenue from Contracts with Customers We disaggregate our revenue from contracts with customers by customer, contract type, as well as whether the Company acts as prime contractor or subcontractor.

(a) Represents the principal amounts payable on our term loan, which is secured by liens on substantially all of the assets of the Company. The principal of the term loan is payable in quarterly installments with the remaining balance due on December 8, 2027. On January 31, 2023, we executed a floating-to-fixed interest rate swap with FNB which has a notional amount of $80.0 million at June 30, 2024 , a fixed interest rate of 4.10% and a maturity date of January 31, 2026. As a result of entering these agreements, for the three and nine months ended June 30, 2024, interest expense has been decreased by approximately $0.3 million and $1.0 million, respectively. The Credit Agreement requires compliance with a number of financial covenants and contains restrictions on our ability to engage in certain transactions. Among other matters, we must comply with limitations on: granting liens; incurring other indebtedness; maintenance of assets; investments in other entities and extensions of credit; mergers and consolidations; and changes in nature of business. The loan agreement also requires us to comply with certain quarterly financial covenants including: (i) a minimum fixed charge coverage ratio of at least 1.25 to 1.00, and (ii) a total leverage ratio not exceeding the ratio of 4.50:1.00 to 2.00:1.00 through maturity. The total leverage ratio is calculated by dividing the Company's total interest-bearing debt by net income adjusted to exclude (i) interest and other expenses, (ii) provision for income taxes (benefit) expense, if any, (iii) depreciation and amortization, and (iv) non-cash charges, losses or expenses, including stock-based compensation, and (v) non-recurring charges, losses or expenses to include transaction and non-cash equity expense. We are in compliance with all loan covenants and restrictions as of June 30, 2024 and September 30, 2023. We are required to pay quarterly amortization payments, which commenced in December 2022. The annual amortization amounts are $14.3 million for fiscal year 2024, $19.0 million each for fiscal years 2025 and 2026, and $23.75 million for fiscal year 2027, with the remaining unpaid loan balance due at maturity in December 2027. The quarterly payments are equal installments. The Company made voluntary prepayments of $7.1 million during nine months ended June 30, 2024 bringing the outstanding principal balance on the secured term loan to $152.0 million. We have satisfied the mandatory principal payments through March 31, 2025. In addition to quarterly payments of the outstanding indebtedness, the loan agreement also requires annual payments of a percentage of excess cash flow, as defined in the loan agreement. The loan agreement states that an excess cash flow recapture payment must be made equal to (a) 75% of the excess cash flow for the immediately preceding fiscal year in which indebtedness to consolidated EBITDA ratio is greater than or equal to 2.5:1; (b) 50% of the excess cash flow for the immediately preceding fiscal year in which the funded indebtedness to consolidated EBITDA Ratio is less than 2.5:1 but greater than or equal to 1.5:1; or (c) 0% of the excess cash flow for the immediately preceding fiscal year in which the funded indebtedness to consolidated EBITDA Ratio is less than 1.5:1. In addition, the Company must make additional mandatory prepayment of amounts outstanding based on proceeds received from asset sales and sales of certain equity securities or other indebtedness. Due to the voluntary prepayment of term debt, there was no excess cash flow payment required. For additional information regarding the schedule of future payment obligations, please refer to Note 10. Commitments and Contingencies . (b) The secured revolving line of credit has a ceiling of up to $70.0 million; as of June 30, 2024, we had unused borrowing capacity of $24.0 million, which is net of outstanding letters of credit. Borrowing on the secured revolving line of credit is secured by liens on substantially all of the assets of the Company. The Company accessed funds from the secured revolving line of credit during the year, which had a $14.5 million outstanding balance at June 30, 2024. As part of the secured revolving line of credit, the lenders agreed to a sublimit of $10.0 million for letters of credit for the account of the Company, subject to applicable procedures.

Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
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, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The most significant of these estimates and assumptions relate to estimating costs including overhead and its allocation, valuing and determining the amortization periods for long-lived intangible assets, interest rate swaps, stock-based compensation, and right-of-use assets and lease liabilities. We evaluate these estimates and judgments on an ongoing basis and base our estimates on historical experience, current and expected future outcomes, third-party evaluations, and various other assumptions that we believe are reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. We revise material accounting estimates if changes occur, such as more experience is acquired, additional information is obtained, or there is new information on which an estimate was or can be based. Actual results could differ from those estimates.
Revenue	Revenue The Company's revenues from contracts with customers are derived from offerings that include technology-enabled business process outsourcing, program management solutions, and public health research and analytics, substantially within the U.S. government and its agencies. The Company has various types of contracts including time-and-materials contracts, cost-reimbursable contracts, and firm-fixed-price contracts. We consider a contract with a customer to exist when there is a commitment by both parties (customer and Company), payment terms are determinable, there is commercial substance, and collectability is probably in accordance with Accounting Standards Codification ("ASC") No. 606, "Revenue from Contracts with Customers" ("Topic 606"). We recognize revenue over time when there is a continuous transfer of control to our customer as performance obligations are satisfied. For our U.S. government contracts, this continuous transfer of control to the customer is transferred over time and revenue is recognized based on the extent of progress toward completion of the performance obligation. We consider control to transfer when we have a right to payment. In some instances, the Company commences providing services prior to formal approval to begin work from the customer. The Company considers these factors, the risks associated with commencing work, and legal enforceability in determining whether a contract exists under Topic 606. Contract modification can occur throughout the life of the contract and can affect the transaction price, extend the period of performance, adjust funding, or create new performance obligations. We review each modification to assess the impact of these contract changes to determine if it should be treated as part of the original performance obligation or as a separate contract. Contract modifications impact performance obligations when the modification either creates new or changes the existing enforceable rights and obligations. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue and profit cumulatively. Furthermore, a significant change in one or more estimates could affect the profitability of our contracts. We recognize adjustments in estimated profit on contracts in the period identified. For service contracts, we satisfy our performance obligations as services are rendered. We use cost-based input and time-based output methods to measure progress based on the contract type. • Time and material - We bill the customer per labor hour and per material, and revenue is recognized in the amount invoiced as the amount corresponds directly to the value of our performance to date. Revenue is recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred. • Cost reimbursable - We record reimbursable costs as incurred, including an estimated share of the contractual fee earned. • Firm fixed price - We recognize revenue over time using a straight-line measure of progress. Contract costs generally include direct costs such as labor, materials, subcontract costs, and indirect costs identifiable with or allocable to a specific contract. Costs are expensed as incurred and include an estimate of the contractual fees earned. Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by various government audit agencies. Historically, our adjustments have not been material. Contract assets - Amounts are invoiced as work progresses in accordance with agreed-upon contractual terms. In part, revenue recognition occurs before we have the right to bill, resulting in contract assets. These contract assets are reported within accounts receivable on our consolidated balance sheets and are invoiced in accordance with payment terms defined in each contract. Period end balances will vary from period to period due to agreed-upon contractual terms. Disaggregation of Revenue from Contracts with Customers
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of the Company's cash, accounts receivable, contract assets, accrued expenses, and accounts payable approximate fair value due to the short-term nature of these instruments. The fair values of the Company's debt instruments approximate fair value because the underlying interest rates approximate market rates that the Company could obtain for similar instruments at the balance sheet dates.
Long-Lived Assets	Long-Lived Assets Our long-lived assets include equipment and improvements, intangible assets, right-of-use assets, and goodwill. The Company continues to review long-lived assets for possible impairment or loss of value at least annually, or more frequently upon the occurrence of an event or when circumstances indicate that a reporting unit's carrying amount is greater than its fair value. Equipment and improvements are recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful asset lives (3 to 7 years) and the shorter of the initial lease term or estimated useful life for leasehold improvements. Maintenance and repair costs are expensed as incurred. Intangible assets (other than goodwill) are originally recorded at fair value and are amortized on a straight-line basis over their estimated useful lives of 10 years.
Right-of-Use Assets and Lease Liabilities	Right-of-use assets are measured at the present value of future minimum lease payments, including all probable renewals, plus lease payments made to the lessor before or at lease commencement and indirect costs paid, less incentives received. Our right-of-use assets include long-term leases for facilities and equipment and are amortized over their respective lease terms. Lease Liabilities The Company has leases for facilities and office equipment. Our lease liabilities are recognized as the present value of the future minimum lease payments over the lease term. Our lease payments consist of fixed and in-substance fixed amounts attributable to the use of the underlying asset over the lease term. Variable lease payments that do not depend on an index rate or are not in-substance fixed payments are excluded in the measurement of right-of-use assets and lease liabilities and are expensed in the period incurred. The incremental borrowing rate on our secured term loan is used in determining the present value of future minimum lease payments. Some of our lease agreements include options to extend the lease term or terminate the lease. These options are accounted for in our right-of-use assets and lease liabilities when it is reasonably certain that the Company will extend the lease term or terminate the lease. The Company does not have any finance leases.
Goodwill	Goodwill The Company reviews goodwill for impairment on an annual basis and on a quarterly basis the Company assesses the impact of any macroeconomic changes that may impact the business conditions to determine if these changes have any adverse impact to goodwill. Notwithstanding this evaluation, factors including non-renewal of a major contract or other substantial changes in business conditions could have a material adverse effect on the valuation of goodwill in future periods and the resulting charge could be material to future periods’ results of operations. The Company determined that no change in business conditions occurred which would have a material adverse effect on the valuation of goodwill.
Income Tax	Income Tax
Stock-based Compensation	Stock-Based Compensation The Company uses the fair value-based method for stock-based compensation. Options issued are designated as either an incentive stock option or a non-statutory stock option. No option may be granted with a term of more than 10 years from the date of grant. Option awards may depend on achievement of certain performance measures determined by the Compensation Committee of our Board. Shares issued upon option exercise are newly issued common shares. All awards t o employees and non- employee s are reco rded at fair value on the date of the grant and expensed over the period of vesting. The Company uses a Monte Carlo method to estimate the fair value of each stock option at the date of grant. Any consideration paid by the option holders to purchase shares is credited to common stock. Stock-based compensation expense for the portion of equity awards for which the requisite service has not been rendered is recognized as the requisite service is rendered. The stock-based compensation expense for that portion of awards has been based on the grant-date fair value of those awards as calculated for recognition purposes under applicable guidance. For options that vest based on the Company’s common stock achieving and maintaining defined market prices, the Company values the awards with a Monte Carlo method that utilizes various probability factors and other criterion in establishing fair value of the grant. The related compensation expense is recognized over the service period.
Cash	Cash
Accounts Receivable	Accounts Receivable Receivables include amounts billed and currently due from customers where the right to consideration is unconditional and amounts unbilled. Both billed and unbilled amounts are non-interest bearing, unsecured, and recognized at an estimated realizable value that includes costs and fees, and are generally expected to be billed and received within a single year. We evaluate our receivables for expected credit losses on a quarterly basis and determine whether an allowance for expected credit losses is appropriate based on specific collection issues.
Earnings Per Share	Earnings Per Share
Treasury Stock and Preferred Stock	Treasury Stock The Company periodically purchases its own common stock that is traded on public markets as part of announced stock repurchase programs. The repurchased common stock is classified as treasury stock on the consolidated balance sheets and held at cost. As of June 30, 2024 and September 30, 2023, the Company did not hold any treasury stock. Preferred Stock
Interest Rate Swap	Interest Rate Swap The Company uses derivative financial instruments to manage interest rate risk associated with its variable debt. The Company's objective in using these interest rate derivatives is to manage its exposure to interest rate movements and reduce volatility of interest expense. The gains and losses due to changes in the fair value of the interest rate swap agreements completely offset changes in the fair value of the hedged portion of the underlying debt. Offsetting changes in fair value of both the interest rate swaps and the hedged portion of the underlying debt are recognized in interest expense in the consolidated statements of operations. The Company does not hold or issue any derivative instruments for trading or speculative purposes.
Risks and Uncertainties	Risks and Uncertainties Management evaluates the impact of global markets and economic factors on our industry and the potential for adverse effects on the Company's consolidated financial position and its operations. As of June 30, 2024 and September 30, 2023 there was no indication of any global or economic impacts to our industry.
New Accounting Pronouncements	New Accounting Pronouncements In November 2023, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which provides guidance intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, and each reported measure of segment profit or loss. The ASU requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this ASU and all existing segment disclosures in Topic 280. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2023 and interim periods beginning after December 15, 2024. We are currently evaluating the impacts of the single reportable segment disclosures. In December 2023, FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" which provides guidance on the requirements such as the requirement that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. DLH is a public company that reports income tax disclosures and therefore this ASU applies to the Company. ASU 2023-09 is effective for public business entities for fiscal years beginning after Dec. 15, 2024. We are currently evaluating the impacts of the improvements to income tax disclosure. In March 2024, FASB issued ASU No. 2024-01, "Scope Application of Profits Interest and Similar Awards". The ASU clarifies how an entity determines whether a profits interest or similar award is (1) within the scope of ASC 718 or (2) not a share-based payment arrangement and therefore within the scope of other guidance. The guidance in ASU 2024-01 applies to all entities that issue profits interest awards as compensation to employees or non-employees in exchange for goods or services. We are currently evaluating the impacts of the improvements to our disclosure. In March 2024, the Securities and Exchange Commission ("SEC") has released a final rule that requires registrants to provide comprehensive climate-related disclosures in their annual reports and registration statements, including those for IPOs, beginning with annual reports for the year ending December 31, 2027, for smaller reporting companies ("SRC"). Registrants must disclose climate-related financial metrics and impacts on their financial estimates and assumptions in a footnote to the audited financial statements. The disclosures will also need to be addressed as part of management’s internal control over financial reporting ("ICFR") and will be subject to the financial statement and ICFR audit (if applicable) of an independent registered public accounting firm. We are currently evaluating the impacts of the improvements to our disclosure.
