The accompanying consolidated financial statements include the accounts of DLH Holdings Corp. and its subsidiaries (together with its subsidiaries, "DLH" or the "Company" and also referred to as "we," "us" and "our"), all of which are wholly owned. All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Certain figures presented for comparative purposes have been reclassified to conform to the presentation adopted in the current period. In management's opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the period ended March 31,June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending September 30, 2019. Amounts as of and for the periods ended March 31,June 30, 2019 and March 31,June 30, 2018 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, 2018 filed with the Securities and Exchange Commission on December 12, 2018.

The VA comprised approximately 67%65% and 63%64% of revenue for the sixnine months ended March 31,June 30, 2019 and 2018, which 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 program. Approximately 58% of the Company's current business base with the VA is derived from nine contracts (for pharmacy services), which are currently operating under extensions through October 31, 2019 pending completion of the procurement process for a new contract. We believe further extensions are possible until the

procurement is completed. A single renewal request for proposal ("RFP") has currently been issued for these contracts that requires the prime contractor be a service-disabled veteran owned small business (SDVOSB)("SDVOSB"), which precludes the Company from bidding on the RFP as a prime contractor. The Company has joined an SDVOSB team as a subcontractor to respond to this RFP. Should the contract be awarded to an SDVOSB partner of DLH, the Company expects to continue to perform a significant amount of the contract's volume of business. The remaining seven contracts for logistics services to the VA are performed under contracts that the Company anticipates will behave been extended through November 2019. An RFP for the seven logistics contracts has been issued and provides for evaluation and award of the contract based on the classification of the bidder, with preference given to an SDVOSB prime contractor. The Company has joined an SDVOSB team to respond to this RFP. Additionally, the Company believes that these contracts willmay similarly be similarly extended during the procurement process, and may be subject to the same requirement of awarding to a SDVOSB prime contractor.

Further, the Company's contract with HHS in support of its Head Start program generated 28%27% and 31%32% of ourits revenue for the sixnine months ended March 31,June 30, 2019 and 2018, respectively. This contract is on a time and materials basis and consists of a base period of four option periods for a total term of five years through April 2020. The Company's Danya subsidiary has provided these and similar services to HHS since 1999. Danya was acquired by the Company in May 2016.

The Company's results of operations, cash flows and financial condition would be materially adversely affected in the event that we were unable to continue our relationship with VA or HHS, or if the amount of services we provide to them was materially reduced. Given the uncertainty regarding both the outcome and the timing of the VA RFPRFP's discussed above, the Company has not reflected any current impact to its financial statements from this event.the award of these contracts.

Revenue by contract type:

Revenue by whether the Company acts as a prime contractor or a subcontractor:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include valuation of goodwill and intangible assets, valuation allowances established against accounts receivable and deferred tax assets, and measurement of loss development on workers’ compensation claims. 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. In particular, a material reduction in the fair value of goodwill could have a material adverse effect on the Company’s financial position and results of operations. We account for the effect of a change in accounting estimate during the period in which the change occurs.

The carrying amounts of the Company's cash and cash equivalents, 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 approximated fair value because the underlying interest rates approximate market rates that the Company could obtain for similar instruments at the balance sheet dates.

Equipment and improvements are stated at cost. 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.

DLH accounts for income taxes in accordance with the 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 sheet 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,June 30, 2019 or September 30, 2018. We report interest and penalties as a component of income tax expense. In the three and sixnine months ended March 31,June 30, 2019 and March 31,June 30, 2018, we recognized no interest and no penalties related to income taxes.

The Company uses the fair value-based method for stock-based equity compensation. Options issued are designated as either an incentive stock 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 binomial simulation option pricing model 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 capital stock.

We consider 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 (“FDIC”) up to $250,000. Deposits held with financial institutions may exceed the $250,000 limit.

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.

Options issued under equity incentive plans are designated as either an incentive stock or a non-statutory stock option. No option is 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,June 30, 2019, there were 1.5 million shares available for grant.

The Company has determined that for the three and sixnine months ended March 31,June 30, 2019 and 2018 there were no significant related party transactions that have occurred which require disclosure through the date that these financial statements were issued.
