DLH HOLDINGS CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

March 31, 2024

1. 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 six months ended March 31, 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 March 31, 2024 and for the six and three months ended March 31, 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.

2. 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.

7

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.

8

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 March 31, 2024 or September 30, 2023. We report interest and penalties as a component of provision for income taxes. During the six months ended March 31, 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 to employees and non-employees are recorded 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.

9

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. No allowance for doubtful accounts was deemed necessary at either March 31, 2024 or September 30, 2023.

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 March 31, 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 March 31, 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 & 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 March 31, 2024, there was no indication of any global or economic impacts to our industry.

3. 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.

10

The amendments in this update are effective for all entities for its annual filings occurring after December 31, 2023, and interim periods 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. The amendments in this update are effective for all entities for its annual filings occurring after December 31, 2023. 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.

A summary of our credit facilities as presented on our consolidated balance sheets as follows (in millions):

March 31, 2024				September 30, 2023
Arrangement	Loan Balance		Interest	Arrangement	Loan Balance		Interest
Secured term loan (a) due December 8, 2027	$	156,750	SOFR1 + 4.1%	Secured term loan (a) due December 8, 2027	$	169,813	SOFR1 + 4.1%

1Secured Overnight Financing Rate ("SOFR") as of March 31, 2024 and September 30, 2023 were 5.3% and 5.3% respectively.

(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 September 19, 2019, we executed a floating-to-fixed interest rate swap with First National Bank ("FNB") as counterparty. The swap has a notional amount of $9.0 million at March 31, 2024, a fixed interest rate of 1.61% and a maturity date of June 7,

16

2024. On January 31, 2023, we executed an additional floating-to-fixed interest rate swap with FNB which has a notional amount of $80.0 million at March 31, 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 six months ended March 31, 2024, interest expense has been decreased by approximately $0.3 million and $0.7 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 March 31, 2024.

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 $5.9 million during six months ended March 31, 2024 bringing the outstanding principal balance on the secured term loan to $156.8 million. We have satisfied the mandatory principal payments through the end of calendar 2024.

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 March 31, 2024, we had unused borrowing capacity of $22.5 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 $14.0 million outstanding balance at March 31, 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.

8. Stock-Based Compensation and Equity Grants

Stock-based compensation expense

Options issued under equity incentive plans were designated as either an incentive stock or a non-statutory stock option. No option was granted with a term of more than 10 years from the date of grant. Exercisability of 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 shares. As of March 31, 2024, there were 0.8 million shares available for grant.

Major Customers

Our revenues are from agencies of the U.S. Federal government. A major customer is defined as a customer from whom we derive at least 10% of our revenues. The following table summarizes revenue by customer as follows (in thousands and percent):

	Six Months Ended
	March 31,
	2024				2023
	Revenue		Percent of total revenue		Revenue		Percent of total revenue
Department of Health and Human Services	$	91,636	46.1	%	$	65,509	38.1	%
Department of Veterans Affairs	70,296		35.4	%	68,591		39.8	%
Department of Defense	33,283		16.7	%	29,235		17.0	%
Other customers with less than 10% share of total revenue	3,642		1.8	%	8,820		5.1	%
Total revenue	$	198,857	100.0	%	$	172,155	100.0	%

We remain dependent upon the continuation of our relationships with our major customers as a significant portion of our revenue is concentrated in each of them. Our results of operations, cash flows and financial condition would be materially adversely affected if we were unable to continue our relationship with any of these customers, if we were to lose any of our material current contracts, or if the amount of services we provide to them is materially reduced.

Major Contracts

We operate primarily through prime contracts awarded by the government through competitive bidding processes. We have a diverse mix of contract vehicles with various agencies of the U.S. government, which supports our overall corporate growth strategy. A major contract is defined as a contract or set of contracts from which we derive at least 10% of our revenues.

The revenue attributable to the VA was derived from 16 separate contracts covering the Company's performance of pharmacy and logistics services in support of the VA's Consolidated Mail Outpatient Pharmacy ("CMOP") program.

•Nine orders for pharmacy services, which represent approximately $39.1 million and $39.4 million of revenues for the six months ended March 31, 2024 and 2023, respectively, and operated under a bridge contract through April 30, 2024.

•Seven orders for logistics services represent approximately $31.2 million and $29.2 million of revenues for the six months ended March 31, 2024 and 2023, respectively, and operated under a bridge contract through April 30, 2024.

•As discussed below, the Company has received a new Indefinite-Delivery Indefinite-Quantity ("IDIQ") contract to continue providing prime contractor services at all eight CMOP locations while the pending procurements are evaluated. The ceiling value of the IDIQ contract is $200.0 million with the initial tasking through July 31, 2024. These initial task orders provide adequate funding to support the expected service volume of approximately $35.0 million for the three month period. Additional task orders may be issued under this IDIQ contract until the end of its period of performance.

The VA has issued eight separate requests for proposals for healthcare logistics and pharmacy services for each of its eight CMOP locations. Each of the eight procurements are being evaluated separately and may be subject to differing timelines for award. The procurements were set-aside for a service-disabled veteran owned small business (“SDVOSB”) as the prime contractor. DLH responded to each request for proposal as a joint venture partner with an SDVOSB prime contractor. While the acquisition process is being conducted, DLH continues to operate as the prime contractor for all CMOP locations.

23

Should the new contracts for performance of these services be awarded to a partner of DLH, the Company expects to continue to perform a significant amount of the contract’s volume of business as a subcontractor. Should the VA conclude that an award to an SDVOSB prime contractor is not in the best interest of the government, they may reissue a solicitation in an unrestricted competition. DLH believes that its service excellence over many years on the program would provide an advantage in any competition.

As disclosed in the Company’s Form 8-K filings during the quarter ended March 31, 2024, the VA has begun the process of evaluating the proposals for the eight solicitations mentioned above. We were advised that the VA had made an award decision for the Chelmsford CMOP Staffing Services location to an SDVOSB unrelated to DLH. Between the announcement of the award and the commencement of the contract, Federal acquisition guidelines provide each of the 17 competitors for this contract the right to a debriefing to explain the results. Based on the debriefing, a bidder may then contest the decision. Our joint venture continues to pursue its remedies under the Federal acquisition regulations. A final award decision on this proposal has not yet been made.

Following the award notice for the Chelmsford location, the VA had apparently reconsidered its options for achieving the transition of CMOP operations to an SDVOSB provider through five-year contracts and issued Notices of Intent to Award Sole Source Procurements for healthcare logistics and pharmacy services by location to various SDVOSBs, including the joint venture between DLH and its SDVOSB partner, for durations of up to three months. These notices were subsequently cancelled by the VA. Accordingly, DLH expects that it will continue providing healthcare logistics and pharmacy services until award decisions on the five-year contracts are completed.

In support of DLH’s continuing performance as the prime contractor during the ongoing acquisition evaluation, the VA awarded us a sole-source IDIQ contract effective May 1, 2024. The IDIQ has a ceiling value of $200 million and a period of performance extendable through April 30, 2025 with the potential for orders placed within that period to extend performance for up to 180 days through October 2025. Initial task orders have been issued for DLH’s prime contractor performance through July 31, 2024.

Backlog

At March 31, 2024, our backlog was approximately $736.2 million, of which $106.9 million was funded backlog. At September 30, 2023, our backlog was approximately $704.8 million, of which $169.9 million was funded backlog.

We define backlog as our estimate of remaining future revenue from existing signed contracts, assuming the exercise of all options relating to such contracts and including executed task orders issued under Indefinite Quantity/Indefinite Delivery ("IDIQ") contracts or if the contract is a single award IDIQ contract.

We define funded backlog as the portion of backlog for which funding is appropriated and allocated to the contract by the customer and authorized for payment by the customer, once specified work is completed. Funded backlog does not include the full contract value as Congress often appropriates funding for contracts on a yearly or quarterly basis.

Circumstances and events may cause changes in the amount of our backlog and funded backlog, including the execution of new contracts, extension of existing contracts, non-renewal or completion of current contracts, early termination, and adjustments to estimates. Changes in funded backlog may be affected by the funding cycles of the government. While no assurances can be given that existing contracts will result in earned revenue in any future period, or at all, our major customers have historically exercised their contractual renewal options.

Backlog value is quantified from management's judgment and assumptions about the volume of services based on past volume trends and current planning developed with customers.

Forward-Looking Business Trends

Our mission is to expand our position as a trusted provider of technology-enabled healthcare and public health services, medical logistics, and readiness enhancement services to active duty personnel, veterans, and civilian populations and communities. Our primary focus within the defense agency markets includes cyber security, military service members' and veterans' requirements for telehealth services, behavioral healthcare, medication therapy management, process management, clinical systems support, and healthcare delivery. Our primary focus within the civilian agency markets includes digital transformation, IT modernization, healthcare and social programs delivery and readiness. These include compliance monitoring on large scale programs, technology-enabled program management, consulting, and digital communications solutions ensuring that education, health, and social standards are being achieved within underserved and at-risk populations. We believe these business development priorities will position the Company to expand within top national priority programs and funded areas.

Federal budget outlook for fiscal year 2025:

The President’s budget proposal for fiscal year ("FY") 2025 outlines initiatives for the federal government in its next operating year. The proposal includes key investments for our customers.

Department of Veterans Affairs

The VA is requesting a total of $369.3 billion for FY 2025, an increase of $32.9 billion above the FY 2024 enacted level. It includes $134.0 billion in discretionary funding, a decrease of $8.9 billion, and $235.3 billion in mandatory funding, an increase of $41.8 billion from FY 2024 budget request. The VA research program is expected to allocate increased funding to advance the Department’s understanding of the impact of traumatic brain injury and toxic exposure(s) on long-term health outcomes, coronavirus related research and impacts, and precision oncology. The FY 2025 budget request for the VA's research enterprise is $2.3 billion, which includes investments in understanding traumatic brain injuries, improving infectious and pandemic preparedness, and preventing suicide.

Department of Health and Human Services

The FY 2025 budget request proposes $1.8 trillion in budget authority for HHS and $1.7 trillion in mandatory funding for the department comprised mainly of spending on Medicare and Medicaid. The budget proposes $46.4 billion in discretionary and mandatory resources for NIH, an increase of $0.9 billion above FY 2024 enacted, to continue making investments in mental health, gun violence research, and women’s health research. The budget also requests $15.7 billion for the Centers for Disease Control and Prevention ("CDC"), an increase of $1.0 billion. The budget also provides for investment in programs that improve the health and well-being of young children and their families. This includes $12.5 billion for the Office of Head Start, principally to expand eligibility for participation in the program.

Department of Defense

The Military Health System ("MHS") is one of the largest health care systems, serving over 9.5 million beneficiaries. As a part of the DoD, the Defense Health Agency ("DHA") manages a global health care network of military and civilian medical professionals, military hospitals and clinics around the world, and supports the delivery of integrated health services to MHS beneficiaries. The funding and personnel to support MHS’s mission is referred to as the Unified Medical Budget ("UMB"). The FY 2025 UMB request for the Defense Health Program ("DHP") is $61.4 billion, an increase of 4.6% from FY 2024 enacted.

Potential impact of federal contractual set-aside laws and regulations:

The Federal government has an overall goal of 23% of prime contracts flowing through small businesses. As previously reported, various agencies within the federal government have policies that support small business goals, including the adoption of the “Rule of Two” by the VA, which provides that the agency shall award contracts by restricting competition for the contract to service-disabled or other veteran-owned businesses. To restrict competition pursuant to this rule, the contracting officer must reasonably expect that at least two of these businesses, which are capable of delivering the services, will submit offers and that the award can be made at a fair and reasonable price that offers best value to the U.S. When two qualifying small businesses cannot be identified, the VA may proceed to award contracts following a full and open bid process.

The Company believes that its past performance in this market and track record of success provide a competitive advantage. However, the effect of set-aside provisions may limit our ability to compete for prime contractor positions on programs that we recompete or that we have targeted for growth. In these cases, the Company may elect to join a team with an eligible contractor as prime for specific pursuits that align with our core markets and corporate growth strategy.

Revenue

Revenue increased $1.6 million for the three months ended March 31, 2024 over 2023, reflecting growth across the Company's programs, particularly in public health and IT services, offset in part by national security contracts converting to small business set-aside companies.

Cost of Operations

Contract costs primarily include the costs associated with providing services to our customers. These costs are generally comprised of direct labor and associated fringe benefit costs, subcontract cost, other direct costs, and the related management and infrastructure costs. Contract costs increased $0.9 million for the three months ended March 31, 2024 over 2023, the increase was primarily due to the increase in revenue

General and administrative costs are for those employees not directly providing services to our customers, to include but not limited to executive management, business development accounting, and human resources. These costs increased $1.0 million for the three months ended March 31, 2024 over 2023. As a percentage of revenue general administrative costs increased to 11.6% from 10.8%, the increase as a percentage of revenue was primarily due to increase in legal costs associated with customer procurements and strategic corporate planning costs.

For the three months ended March 31, 2024, depreciation and amortization expense were approximately $0.1 million and $4.1 million, respectively, as compared to approximately $0.2 million and $4.3 million for the three months ended March 31, 2023, respectively.

26

Interest Expense, net

Interest expense, net, includes interest expense on the Company's term loan and amortization of deferred financing costs on debt obligations. Interest expense decreased $0.6 million for the three months ended March 31, 2024 over 2023, primarily due to the prepayment of debt resulting in reduced interest payments.

Provision for Income Tax Expense and Benefit

Provision for income tax expense and benefit decreased $0.4 million for the three months ended March 31, 2024 over 2023. The effective tax rate for the three months ended March 31, 2024 and 2023 was (3.4)% and 32.1%, respectively. The decrease in the tax provision is primarily due to the beneficial impact of stock-based compensation expense as options are exercised.

The following table summarizes results of operations for the six months ended March 31, 2024 and 2023 (in thousands except for per share amounts, and percentage of revenue):

	Six Months Ended

Revenue

Revenue increased $26.7 million for the six months ended March 31, 2024 over 2023 . The increase in revenue is primarily due to the December 2022 acquisition.

Cost of Operations

Contract costs primarily include the costs associated with providing services to our customers. These costs are generally comprised of direct labor and associated fringe benefit costs, subcontract cost, other direct costs, and the related management and infrastructure costs. Contract costs increased $22.7 million for the six months ended March 31, 2024 over 2023. The increase in costs is primarily due to increased revenue.

General and administrative costs are for those employees not directly providing services to our customers, to include but not limited to executive management, business development, accounting, and human resources. These costs increased $1.3 million for the six months ended March 31, 2024 over 2023. As a percentage of revenue general administrative costs decreased to 9.8% from 10.5%. The decrease was primarily due to increased operating leverage and timing of strategic corporate planning and business development expenses.

27

For the six months ended March 31, 2024, depreciation and amortization expense were approximately $0.3 million and $8.2 million, respectively, as compared to approximately $0.4 million and $6.5 million for the six months ended March 31, 2023, respectively.

Interest Expense, net

Interest expense, net, includes interest expense on the Company's term loan and amortization of deferred financing costs on debt obligations. Interest expense increased $2.3 million for six months ended March 31, 2024 over 2023, primarily due to the borrowing required to finance the December 2022 acquisition.

Provision for Income Tax Expense and Benefit

Provision for income tax expense and benefit decreased $1.0 million for the six months ended March 31, 2024 over 2023. The effective tax rate for the six months ended March 31, 2024 and 2023 was (1.3)% and 28.2%, respectively. The decrease in the tax provision is primarily due to the beneficial impact of stock based compensation expense as options are exercised..

Non-GAAP Financial Measures

The Company uses EBITDA as a supplemental non-GAAP measure of our performance. DLH defines EBITDA as net income excluding (i) interest expense, (ii) income tax expense and benefit, and (iii) depreciation and amortization.

On a non-GAAP basis, Earnings Before Interest, Tax, Depreciation, and Amortization ("EBITDA") for the six months ended March 31, 2024 and 2023 was approximately $21.3 million and $16.8 million, respectively. The increase was principally due to the contribution of the December 2022 acquisition.

This non-GAAP measure of our performance is used by management to conduct and evaluate its business during its regular review of operating results for the periods presented. Management and our Board utilize this non-GAAP measure to make decisions about the use of our resources, analyze performance between periods, develop internal projections and measure management's performance. We believe that this non-GAAP measure is useful to investors in evaluating our ongoing operating and financial results and understanding how such results compare with our historical performance. By providing this non-GAAP measure as a supplement to GAAP information, we believe this enhances investors understanding of our business and results of operations. EBITDA is not a recognized measurement under accounting principles generally accepted in the United States, or GAAP, and when analyzing our performance investors should (i) evaluate adjustments in our reconciliation to the nearest GAAP financial measures and (ii) use non-GAAP measures in addition to, and not as an alternative to, measures of our operating results as defined under GAAP.

A summary of the change in cash is presented as follows (in thousands):

	Six Months Ended
	2024		2023		Change
Net cash provided by operating activities	$	10,301	$	6,862	$	3,439
Net cash used in investing activities	(466)		(181,174)		180,708
Net cash (used in) provided by financing activities	(9,812)		174,221		(184,033)
Net change in cash	$	23	$	(91)	$	114

Cash flows provided by operating activities totaled approximately $10.3 million and $6.9 million for the six months ended March 31, 2024 and 2023, respectively. The increase in cash from operations was principally due to a improvement in the collection cycle for accounts receivable.

Cash used in investing activities totaled $0.5 million and $181.2 million for the six months ended March 31, 2024 and 2023, respectively. The cash utilized in the prior fiscal year period was predominantly due to the December 2022 acquisition.

Cash used in and provided by financing activities during the six months ended March 31, 2024 and 2023 were approximately $9.8 million and $174.2 million, respectively, was principally due to retiring outstanding term debt while in the six months ended March 31, 2023 the cash provided was to finance the December 2022 acquisition.

Sources of cash

As of March 31, 2024, our immediate sources of liquidity include cash of approximately $0.2 million, accounts receivable, and access to our secured revolving line of credit facility. This credit facility provides us with access of up to $70.0 million, subject to certain conditions including eligible accounts receivable. As of March 31, 2024, we had unused borrowing capacity of $22.5 million, which is net of outstanding letters of credit. The Company's present operating liabilities are largely predictable and consist of vendor and payroll related obligations. We believe that our current investment and financing obligations are adequately covered by cash generated from profitable operations and that planned operating cash flow should be sufficient to support our operations for twelve months from the date of issuance of these consolidated financial statements.

1Secured Overnight Financing Rate ("SOFR") as of March 31, 2024 was 5.3%.

On September 19, 2019, we executed a floating-to-fixed interest rate swap with First National Bank ("FNB") as counter party. The swap has a notional of $9.0 million at March 31, 2024, a fixed interest rate of 1.61% and a maturity date of June 7, 2024. On January 31, 2023, we executed an additional floating-to-fixed interest rate swap with FNB which has a notional amount of $80.0 million at March 31, 2024, a fixed interest rate is 4.10% and a maturity date of January 31, 2026. As a result of entering these agreements, for the six months ended March 31, 2024, interest expense has been decreased by approximately $0.7 million.

(b) The secured revolving line of credit has a ceiling of up to $70.0 million and a maturity date of December 8, 2027. The Company has accessed funds from the revolving credit facility during the quarter and has a balance outstanding at March 31, 2024 of $14.0 million

The secured term loan and secured revolving line of credit are secured by liens on substantially all of the assets of the Company. The provisions of our credit facilities are fully described in Note 7. Credit Facilities to the consolidated financial statements.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in the Critical Accounting Policies and Estimates section in Part II, “Item 7. Management's Discussion of our Annual Report on Form 10-K for the year ended September 30, 2023. There have been no significant changes to the Company’s critical accounting policies as disclosed in our Annual Report on Form 10-K for the year ended September 30, 2023. For a detailed discussion on the application of accounting policies, refer to Note 2. Significant Accounting Policies.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Except as described elsewhere in this report, the Company has not engaged in trading practices in securities or other financial instruments and therefore does not have any material exposure to interest rate risk, foreign currency exchange rate risk, commodity price risk or other similar risks, which might otherwise result from such practices. The Company has limited foreign operations and therefore is not materially subject to fluctuations in foreign exchange rates, commodity prices or other market rates or prices from market sensitive instruments. We have executed a set of floating-to-fixed interest rate swaps with a total notional amount of $89 million at March 31, 2024. The remaining balance of our debt is subject to floating interest rates.

We have determined that a 1.0% increase to SOFR would impact our interest expense by approximately $0.8 million per year. As of March 31, 2024, the interest rate on the floating interest rate debt was 9.4%.

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our CEO and President and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based on the evaluation of these controls and procedures, our disclosure controls and procedures were effective at the reasonable assurance level to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 (i) is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and (ii) that such information is accumulated and communicated to our management, including our CEO and President and Chief Financial Officer, to allow timely decisions regarding required disclosure.

30

Our management, including our CEO and President and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. Our management, however, believes our disclosure controls and procedures are in fact effective to provide reasonable assurance that the objectives of the control system are met.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) identified in connection with the evaluation of our internal controls that occurred during the fiscal quarter ended March 31, 2024, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II OTHER INFORMATION 

ITEM 1: LEGAL PROCEEDINGS

As a commercial enterprise and employer, the Company is subject to various claims and legal actions in the ordinary course of business. These matters can include professional liability, workers’ compensation, tax, payroll and employee-related matters, other commercial disputes arising in the course of its business, and inquiries and investigations by governmental agencies regarding our employment practices or other matters. The Company is not aware of any pending or threatened litigation that it believes is reasonably likely to have a material adverse effect on its results of operations, financial position or cash flows.

ITEM 1A: RISK FACTORS

Our operating results and financial condition have varied in the past and may in the future vary significantly depending on a number of factors. In addition to the other information set forth in this report, you should carefully consider the factors discussed in the “Risk Factors” section in our Annual Report on Form 10-K for the year ended September 30, 2023, in our Quarterly Report on Form 10-Q for the quarter ended December 31, 2023, and in our other reports filed with the SEC concerning the risks associated with our business, financial condition and results of operations. These factors, among others, could materially and adversely affect our business, results of operations, financial condition or liquidity and cause our actual results to differ materially from those contained in statements made in this report and presented elsewhere by management from time to time. The risks we have identified in our reports are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial may also materially adversely affect our business, results of operations, financial condition or liquidity. See Item 1A, Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. We believe that there have been no material changes from the risk factors described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

ITEM 2: UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the period covered by this report, the Company did not issue any securities that were not registered under the Securities Act of 1933, as amended, except as has been reported in previous filings with the SEC or as set forth elsewhere herein. 

ITEM 3: DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4: MINE SAFETY DISCLOSURES

Not applicable.

ITEM 5: OTHER INFORMATION

31

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 six months ended March 31, 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 March 31, 2024 and for the six and three months ended March 31, 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

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 March 31, 2024 or September 30, 2023. We report interest and penalties as a component of provision for income taxes. During the six months ended March 31, 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 to employees and non-employees are recorded 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. No allowance for doubtful accounts was deemed necessary at either March 31, 2024 or September 30, 2023.

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 March 31, 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 March 31, 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 & 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 March 31, 2024, 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 its annual filings occurring after December 31, 2023, and interim periods 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. The amendments in this update are effective for all entities for its annual filings occurring after December 31, 2023. 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.

March 31, 2024				September 30, 2023
Arrangement	Loan Balance		Interest	Arrangement	Loan Balance		Interest
Secured term loan (a) due December 8, 2027	$	156,750	SOFR1 + 4.1%	Secured term loan (a) due December 8, 2027	$	169,813	SOFR1 + 4.1%
Secured revolving line of credit (b) due December 8, 2027	$	14,022	SOFR1 + 4.1%	Secured revolving line of credit (b) due December 8, 2027	$	9,546	SOFR1 + 4.1%

1Secured Overnight Financing Rate ("SOFR") as of March 31, 2024 and September 30, 2023 were 5.3% and 5.3% respectively.

(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 September 19, 2019, we executed a floating-to-fixed interest rate swap with First National Bank ("FNB") as counterparty. The swap has a notional amount of $9.0 million at March 31, 2024, a fixed interest rate of 1.61% and a maturity date of June 7,

2024. On January 31, 2023, we executed an additional floating-to-fixed interest rate swap with FNB which has a notional amount of $80.0 million at March 31, 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 six months ended March 31, 2024, interest expense has been decreased by approximately $0.3 million and $0.7 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 March 31, 2024.

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 $5.9 million during six months ended March 31, 2024 bringing the outstanding principal balance on the secured term loan to $156.8 million. We have satisfied the mandatory principal payments through the end of calendar 2024.

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 March 31, 2024, we had unused borrowing capacity of $22.5 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 $14.0 million outstanding balance at March 31, 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.

Stock-Based Compensation and Equity Grants

Stock-Based Compensation and Equity Grants

Stock-based compensation expense

Options issued under equity incentive plans were designated as either an incentive stock or a non-statutory stock option. No option was granted with a term of more than 10 years from the date of grant. Exercisability of 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 shares. As of March 31, 2024, there were 0.8 million shares available for grant.

Stock-based compensation expense shown in the table below, is recorded in general and administrative expenses in our consolidated statements of operations as follows (in thousands):

	Three Months Ended				Six Months Ended

Total stock option expense	$	954	$	800	$	1,573	$	1,352

(a) Included in this amount are equity grants of restricted stock units ("RSU") to Executive Officers, which were issued in accordance with the DLH long-term incentive compensation policy in this fiscal year, including both RSU and stock option grants to employees during prior fiscal years. The RSUs issued and outstanding totaled 429,320 and 337,578 at March 31, 2024 and 2023, respectively. During the three months ended March 31, 2024, there was no grant awarded to Executive Officers. For the six months ended March 31, 2024, 169,544 RSUs were granted to Executive Officers. Of the RSUs granted, 84,773 have performance-based vesting criteria and the remaining 84,771 have service-based vesting criteria. The RSUs granted during the six months ended March 31, 2024, were valued as follows using the Monte Carlo Method, and will be amortized over the 3-year measurement period.

(b) Equity grants of RSUs were made in accordance with DLH compensation policy for non-employee directors and a total of 61,525 and 50,367 restricted stock units were issued and outstanding at March 31, 2024 and 2023, respectively. These grants have service-based vesting criteria and vest at the end of this fiscal year.

The fair value of RSUs issued during the six months ended March 31, 2024 is presented in the table below:

Significant Accounting Policies (Policies)

6 Months Ended

Mar. 31, 2024

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

We disaggregate our revenue from contracts with customers by customer, contract type, as well as whether the Company acts as prime contractor or subcontractor. We believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

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

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.

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 to employees and non-employees are recorded 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

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

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. No allowance for doubtful accounts was deemed necessary at either March 31, 2024 or September 30, 2023.

Earnings Per Share

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 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 March 31, 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.

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 & 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 March 31, 2024, 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 its annual filings occurring after December 31, 2023, and interim periods 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. The amendments in this update are effective for all entities for its annual filings occurring after December 31, 2023. 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.
