NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2021
UNAUDITED

1.Description of the Business

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) provides mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies. We excel in full-spectrum cyber, data collection & analytics, enterprise information technology (IT) and systems engineering and software application development solutions that support national and homeland security.

2.Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in the annual financial statements, prepared in accordance with accounting principles generally accepted in the U.S., have been condensed or omitted pursuant to those rules and regulations. The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. We recommend that you read these condensed consolidated financial statements in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, previously filed with the SEC. We believe that the condensed consolidated financial statements in this Form 10-Q reflect all adjustments that are necessary to fairly present the financial position, results of operations and cash flows for the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results that can be expected for the full year.

We classify indirect cost incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2021, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2021 as compared to 2020; however, total operating costs were not affected by this change.

3.Revenue from Contracts with Customers

We derive revenue from contracts with customers primarily from contracts with the U.S. government in the areas of defense, intelligence, homeland security and other federal civilian agencies. Substantially all of our revenue is derived from services and solutions provided to the U.S. government or to prime contractors supporting the U.S. government, including services by our employees and our subcontractors, and solutions that include third-party hardware and software that we purchase and integrate as a part of our overall solutions. Customer requirements may vary from period-to-period depending on specific contract and customer requirements. We provide our services and solutions under three types of contracts: cost-reimbursable, fixed-price and time-and-materials. Under cost-reimbursable contracts, we are reimbursed for costs that are determined to be reasonable, allowable and allocable to the contract and paid a fee representing the profit margin negotiated between us and the contracting agency, which may be fixed or performance based. Under fixed-price contracts, we perform specific tasks for a fixed price. Fixed-price contracts may include either a product delivery or specific service performance over a defined period. Under time-and-materials contracts, we are reimbursed for labor at fixed hourly rates and are generally reimbursed separately for allowable materials and expenses at cost.

For contracts that do not meet the criteria to measure performance as a right to invoice under the series guidance, we utilize an Estimate at Completion process to measure progress toward completion. We typically estimate progress towards completion based on cost incurred or direct labor incurred. As part of this process, we review information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenue and costs. The risks and opportunities include judgments about the ability and cost to achieve the contract milestones and other technical contract requirements. We make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer and overhead cost rates, among other variables. A significant change in one or more of these estimates could affect the timing in which we recognize revenue on our contracts. For the three months ended June 30, 2021 and 2020, the aggregate impact of adjustments in contract estimates increased our revenue by $5.7 million and $5.8
8


million, respectively. For six months ended June 30, 2021 and 2020, the aggregate impact of adjustments in contract estimates increased our revenue by $6.7 million and $7.2 million, respectively.

We have one reportable segment. Our U.S. government customers typically exercise independent decision-making and contracting authority. Offices or divisions within an agency or department of the U.S. government may directly, or through a prime contractor, use our services as a separate customer as long as the customer has independent decision-making and contracting authority within its organization. We treat sales to U.S. government customers as sales within the U.S. regardless of where the services are performed. We generated 100% and 99% of our revenue from sales in the U.S. for each of the three months ended June 30, 2021 and 2020, respectively. We generated 100% and 99% of our revenue from sales in the U.S. for each of the six months ended June 30, 2021 and 2020, respectively.

The following tables disclose revenue (in thousands) by contract type, customer and contractor type for the periods presented.

Revenue$648,578 $632,492 $1,281,802 $1,243,404 

The components of our receivables are as follows (in thousands):
June 30, 2021December 31, 2020
Billed receivables$364,760 $312,991 
Unbilled receivables112,002 106,007 
Allowance for doubtful accounts(17,918)(18,377)
Receivables—net$458,844 $400,621 

Receivables at June 30, 2021 are expected to be substantially collected within one year except for approximately $5.3 million, of which a majority is related to U.S. government receivables. We do not believe that we have significant exposure to credit risk as billed receivables and unbilled receivables are primarily due from the U.S. government. The allowance for doubtful accounts represents our estimate for exposure due to compliance, contractual issues and bad debts related to prime contractors.

At June 30, 2021 and December 31, 2020, our contract liabilities are $30.6 million and $37.2 million, respectively. Changes in the balance of contract liabilities are primarily due to the timing difference between our performance and our customers' payments. For the three months ended June 30, 2021, the amount of revenue that was included in the opening
9


contract liabilities balance was $3.9 million. For the six months ended June 30, 2021, the amount of revenue that was included in the opening contract liabilities balance was $29.4 million.

The remaining performance obligation as of June 30, 2021 is $2.4 billion. The following table discloses when we expect to recognize the remaining performance obligation as revenue (in billions):

4.Acquisitions

Tapestry Technologies (Tapestry)—On December 11, 2020, we completed the acquisition of Tapestry through a share purchase agreement by and among ManTech International Corporation, Tapestry Technologies, Inc., Project Tribune Holdings, Inc. (Holdco), and all of the shareholders of the Holdco. Tapestry provides unique insight and cybersecurity solutions to the U.S. Defense Information Systems Agency (DISA) and the Department of Defense (DoD). This acquisition broadens our footprint with DISA, serves as a springboard into the broader Defense Department IT marketspace, and provides us access to well-funded DISA and DoD programs.

The acquisition was accounted for as a business combination. The results of Tapestry's operations have been included in our condensed consolidated financial statements since that date. We funded the acquisition with cash on hand and borrowing under our revolving credit facility.

The purchase price of $46.3 million has been preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was recorded as goodwill. As we are still in the process of reviewing the fair value of the assets acquired and liabilities assumed, the purchase price allocation for Tapestry is not complete as of June 30, 2021. In accordance with ASC 805, Business Combinations, we expect to finalize our purchase price allocation within one year of the acquisition date.

Recognition of goodwill is largely attributed to the value paid for Tapestry's capabilities, which will broaden our footprint within DISA and the Defense Department IT marketplace. The goodwill recorded for this transaction will be deductible for tax purposes over 15 years. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $15.1 million and $1.4 million, respectively. The fair values of the customer relationships and backlog were determined using the excess earnings method (income approach) in which the value is derived from an estimation of the after-tax cash flows specifically attributable to backlog and customer relationships. Assumptions used in the analysis included revenue and expense forecasts, contributory asset charges, tax amortization benefit and discount rates. Customer contracts and related relationships represent the underlying relationships and agreements with Tapestry's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful lives of approximately 20 years. Backlog is amortized using the pattern of benefits method over its estimated useful life of 2 years. The weighted-average amortization period of other intangibles is 18 years.

Minerva Engineering (Minerva)—On November 9, 2020, we completed the acquisition of Minerva through a membership interest purchase agreement by and among ManTech International Corporation, Minerva Engineering, LLC and NH Holdco LLC. Minerva is a leading provider of advanced cyber services that support the intelligence community, including risk and vulnerability assessment, incident response and cyber intrusion detection, and wireless signal discovery. This acquisition enhances and expands our cyber defense capabilities within the intelligence community, adding new customers, new past performance qualifications, mission-critical contracts, and highly skilled, cleared professionals that increase our deep cyber security talent base.

The acquisition was accounted for as a business combination. The results of Minerva's operations have been included in our condensed consolidated financial statements since that date. We paid for the acquisition with cash on November 9, 2020 and a short-term promissory note that was paid on November 12, 2020.

The preliminary purchase price, which includes an estimated working capital adjustment, was $32.7 million. The preliminary purchase price has been preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was recorded as goodwill. As we are still in the process of reviewing the fair value of the assets acquired and liabilities assumed, the purchase price allocation for Minerva is not complete as of June 30, 2021. In accordance with ASC 805, Business Combinations, we expect to finalize our purchase price allocation within one year of the acquisition date.

Recognition of goodwill is largely attributed to the value paid for Minerva's capabilities, which will broaden our footprint within the intelligence community through the addition of differentiated capabilities and access to new customers and contracts. The goodwill recorded for this transaction will be deductible for tax purposes over 15 years. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $10.5 million and $1.1 million, respectively. The fair values of the customer relationships and backlog were determined using the excess earnings method (income approach) in which the value is derived from an estimation of the after-tax cash flows specifically attributable to backlog and customer relationships. Assumptions used in the analysis included revenue and expense forecasts, contributory asset charges, tax amortization benefit and discount rates. Customer contracts and related relationships represent the underlying relationships and agreements with Minerva's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful lives of approximately 20 years. Backlog is amortized using the pattern of benefits method over its estimated useful life of 2 years. The weighted-average amortization period for other intangible assets is 18 years.

5.Earnings Per Share

Under ASC 260, Earnings per Share, the two-class method is an earnings allocation formula that determines earnings per share for each class of common stock according to dividends declared (or accumulated) and participation rights in undistributed earnings. Under that method, basic and diluted earnings per share data are presented for each class of common stock.

In applying the two-class method, we determined that undistributed earnings should be allocated equally on a per share basis between Class A and Class B common stock. Under our Certificate of Incorporation, the holders of the common stock are entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends as may be declared by the Board of Directors. During the six months ended June 30, 2021 and 2020, we declared and paid two quarterly dividends in the amounts of $0.38 per share and $0.32 per share, respectively, on both classes of common stock.

Basic earnings per share has been computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during each period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period in which the shares were outstanding. Diluted earnings per share have been computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares that were outstanding during each period.

For the three months ended June 30, 2021 and 2020, options to purchase 428 shares and 228,816 shares, respectively, were outstanding but not included in the computation of diluted earnings per share because the options' effect would have been anti-dilutive. For the six months ended June 30, 2021 and 2020, options to purchase 411 shares and 231,938 shares, respectively, were outstanding but not included in the computation of diluted earnings per share because the options' effect would have been anti-dilutive. For the six months ended June 30, 2021 and 2020, there were 125,534 shares and 103,660 shares, respectively, issued from the exercise of stock options.

Revolving Credit Facility—We maintain a credit facility with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The credit agreement provides for a $500 million revolving credit facility, with a $75 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments. The maturity date is August 17, 2022.

Borrowings under our credit agreement are collateralized by substantially all of our assets and those of our Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the
14


time of borrowing: a London Interbank Offer Rate base rate plus market-rate spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio).

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain leverage ratios and a consolidated coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain other actions. As of and during the six months ended June 30, 2021 and 2020, we were in compliance with the financial covenants under the credit agreement.

There was $30.0 million and $15.0 million outstanding on our revolving credit facility at June 30, 2021 and December 31, 2020, respectively. The maximum available borrowing under the revolving credit facility at June 30, 2021 was $467.9 million. As of June 30, 2021, we were contingently liable under letters of credit totaling $2.1 million, which reduces our availability to borrow under our revolving credit facility.

9.Commitments and Contingencies

Contracts with the U.S. government, including subcontracts, are subject to extensive legal and regulatory requirements and, from time-to-time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of us, whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil or criminal liabilities, including repayments, fines or penalties being imposed upon us, or could lead to suspension or debarment from future U.S. government contracting activities. Management believes it has adequately reserved for any losses that may be experienced from any investigation of which it is aware. The Defense Contract Audit Agency has substantially completed our incurred cost audits through 2018 with no material adjustments. The remaining audits for 2019 through 2020 are not expected to have a material effect on our financial position, results of operations or cash flow and management believes it has adequately reserved for any losses.

In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and have litigation pending under several suits. We believe that the ultimate resolution of these matters will not have a material effect on our financial position, results of operations or cash flows.

We have $2.1 million outstanding on our letter of credit, of which $1.6 million is related to an outstanding performance bond in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company to fulfill technical support requirements for the Royal Saudi Air Force.

10.Stock-Based Compensation

Our 2016 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. The types of awards available under the Plan include, among others, stock options, restricted stock and restricted stock units (RSUs), among others. Equity awards granted under the Plan are settled in shares of Class A common stock. At the beginning of each year, the Plan provides that the number of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and Class B common stock outstanding on December 31st of the previous year. On January 2, 2021, there were 607,066 additional shares made available for issuance under the Plan. Through June 30, 2021, the Board of Directors has authorized the issuance of up to 16,358,071 shares under this Plan. Through June 30, 2021, the remaining aggregate number of shares of our common stock available for future grants under the Plan was 7,690,133. The Plan expires in March 2026.

The Plan is administered by the compensation committee of our Board of Directors, along with its delegates. Subject to the express provisions of the Plan, the committee has the Board of Directors’ authority to administer and interpret the Plan, including the discretion to determine the exercise price, vesting schedule, contractual life and the number of shares to be issued.

Stock Compensation Expense—For the three months ended June 30, 2021 and 2020, we recorded $4.2 million and $2.9 million, respectively, of stock-based compensation expense. For the six months ended June 30, 2021 and 2020, we recorded $7.6 million and $5.5 million, respectively, of stock-based compensation expense. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the three months ended June 30, 2021 and 2020, we recorded $0.5 million and $0.3 million, respectively, to income tax benefit related to the
15


exercise of stock options, vested cancellations and the vesting of restricted stock and restricted stock units. For the six months ended June 30, 2021 and 2020, we recorded $1.5 million and $0.8 million, respectively, to income tax benefit related to the exercise of stock options, vested cancellations and the vesting of restricted stock and restricted stock units.

Stock Options—Under the Plan, we have issued stock options in the past. A stock option gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined price for a specific period of time. We did not grant any options during the six months ended June 30, 2021 and year ended December 31, 2020.

We have used the Black-Scholes-Merton option pricing model to determine the fair value of our awards on the date of grant. We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model. Option grants that vested during the six months ended June 30, 2021 and 2020 had a combined fair value of $1.1 million and $1.7 million, respectively.

Unrecognized compensation expense related to non-vested awards was $1.8 million as of June 30, 2021, which is expected to be recognized over a weighted-average period of 1 year.

Restricted Stock—Under the Plan, we have issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors vest on the one year anniversary of the grant date. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock. The grant date fair value of the restricted stock is equal to the closing market price of our common stock on the date of grant.

Non-vested restricted stock at June 30, 202124,000 $86.01 

RSUs—Under the Plan, we have issued restricted stock units (RSUs). RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and have no voting rights until the RSUs vest. Employees who are granted RSUs do not receive dividend payments during the vesting period. Our employees' time-based RSUs generally provide for the delivery of shares in one-third increments on the first, second and third anniversaries of the date of grant. The grant date fair value of the RSUs is equal to the closing market price of our common stock on the grant date less the present value of dividends expected to be awarded during the service period. We recognize the grant date fair value of RSUs of shares we expect to issue as compensation expense ratably over the requisite service period.

11. Subsequent Events

On July 20, 2021, we amended and restated our revolving credit facility (Third Amended and Restated Credit Agreement) with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The Third Amended and Restated Credit Agreement includes credit facilities in an aggregate principal amount of up to $1.1 billion, made available through (i) a $500 million revolving credit facility (Revolving Credit Facility), and (ii) a $600 million delayed-draw term loan facility (Term Facility). Each of the Revolving Credit Facility and the Term Facility matures on July 20, 2026. Under the Term Facility, borrowings are available to be drawn prior to the first anniversary of the Third Amended and Restated Credit Agreement in up to three separate drawings in a minimal amount of $50 million. The Third Amended and Restated Credit Agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments.

The Third Amended and Restated Credit Agreement requires us to comply with specified financial covenants, including the maintenance of certain leverage ratios and a consolidated interest coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain other actions.

Borrowings under our amended and restated credit agreement are collateralized by substantially all of our assets and those
17


of our Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: a London Interbank Offer Rate base rate plus market-rate spreads (1.25% to 2.00% based on our consolidated total leverage ratio) or Bank of America's prime rate plus market spreads (0.25% to 1.00% based on our consolidated net leverage ratio).

We incurred $3.3 million in related fees which will be deferred and amortized over the term of the amended and restated credit agreement.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Cautionary Note Regarding Forward-Looking Statements

All statements and assumptions contained in this Quarterly Report on Form 10-Q that do not relate to historical facts constitute "forward-looking statements." These statements can be identified by the fact that they do not relate strictly to historical or current facts. Forward-looking statements often include the use of words such as "may," "will," "expect," "intend," "anticipate," "believe," "estimate," "plan" and words and terms of similar substance in connection with discussions of future events, situations or financial performance. While these statements represent our current expectations, no assurance can be given that the results or events described in such statements will be achieved.

Forward-looking statements may include, among other things, statements with respect to our financial condition, results of operations, prospects, business strategies, competitive position, growth opportunities, and plans and objectives of management. Such statements are subject to numerous assumptions, risks, uncertainties and other factors, many of which are outside of our control, and include, without limitations, the risks and uncertainties discussed in the Item 1A "Risk Factors" in Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Factors or risks that could cause our actual results to differ materially from the results we anticipate include, but are not limited to, the following:

failure to maintain our relationship with the U.S. government, or the failure to compete effectively for new contract awards or to retain existing U.S. government contracts;
adverse changes in U.S. government spending for programs we support, whether due to changing mission priorities, socio-economic policies or federal budget constraints generally;
disruptions to our business or damage to our reputation resulting from cyber attacks and other security threats;
disruptions to our business resulting from the COVID-19 pandemic or other similar global health epidemics, pandemics and/or other disease outbreaks;
inability to recruit and retain a sufficient number of employees with specialized skill sets or necessary security clearances who are in great demand and limited supply;
failure to compete effectively for awards procured through the competitive bidding process, and the adverse impact of delays resulting from our competitors' protests of new contracts that are awarded to us;
failure to obtain option awards, task orders or funding under our contracts;
the government renegotiating, modifying or terminating our contracts;
failure to comply with, or adverse changes in, complex U.S. government laws and procurement regulations;
adverse results of U.S. government audits or other investigations of our government contracts;
failure to successfully integrate acquired companies or businesses into our operations or to realize any accretive or synergistic effects from such acquisitions;
failure to mitigate risks associated with conducting business internationally; and
adverse changes in business conditions that may cause our investments in recorded goodwill to become impaired.

We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report. We undertake no obligation to update any forward-looking statement made herein following the date of this Quarterly Report, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

Overview

We provide mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies. We excel in full-spectrum cyber, secure mission & enterprise IT, advanced data analytics, software and systems development, intelligent systems engineering, intelligence mission support and mission operations.

18


Approximately 99% of our revenues are generated through contracts with the U.S. federal government, or through prime contractors supporting the U.S. government. The U.S. government is the largest consumer of services and solutions in the U.S. As such, our business is impacted by the overall U.S. government budget and our ability to match our capabilities and offerings to the U.S. government's spending priorities. On December 27, 2020, Congress passed, and the President signed into law the Consolidated Appropriations Act of 2020. The Consolidated Appropriations Act funds the federal government through GFY 2021 and contains $696 billion of funding for defense. The President's proposal for GFY 2022 contains $753 billion for defense and $769 billion for non-defense. Included within the proposal is $20 billion for unclassified cyber, representing 9% year-over-year growth and $97 billion for IT modernization, representing 4% year-over-year growth.

On August 1, 2021, the suspension of the U.S. statutory debt ceiling limit expired. If Congress fails to increase or further suspend the debt ceiling prior to exhausting its monetary resources, the U.S. government could experience a shutdown or be unable to make payments which could have a material adverse effect on our liquidity and results of operations.

COVID-19 Pandemic

We are continuing to monitor impacts of the global outbreak of the COVID-19 pandemic including new variants of the virus. With the rollout of the vaccine, previous measures adopted by local, state and federal governments to mitigate its impact have been, or are in the process of being, lifted. The removal of these mitigation protocols has allowed a majority of our previously impacted programs to return to normal operations.

For programs that had been impacted or are still being impacted, the Coronavirus Aid, Relief and Economic Security (CARES) Act, enacted on March 27, 2020, included a provision (Section 3610) under which government contractors can seek reimbursement for employee's salaries when they are prevented from accessing worksites or are subject to reduced work schedules and cannot telecommute. These provisions were extended on March 11, 2021 when the President signed into law the American Rescue Plan (ARP) Act of 2021. The ARP Act is a $1.9 trillion stimulus package aimed at further combating the economic impacts of the COVID-19 pandemic. The extension contained within the ARP Act expires on September 30, 2021. The precise application of this provision, including what type of costs will be reimbursed, the earliest date cost-reimbursement will be applicable, and whether fee recovery will be included in the reimbursement, are determinations being made at the individual government agency or contract level. Currently, our customers are reimbursing costs incurred without fee. We cannot predict the duration of the pandemic, nor the overall effectiveness of the vaccine, however, an extended duration or resurgence of the pandemic may have an adverse impact on our results of operations.

We classify indirect expenses either as cost of services or general and administrative in manner consistent with disclosure statements submitted and approved by the Defense Contract Management Agency (DCMA). Effective for 2021, we have reclassified certain expenses from general and administrative to cost of sales (overhead). While this does not impact indirect expenses in total, it does reduce general and administrative as compared to prior periods.

We recommend that you read this discussion and analysis in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, previously filed with the Securities and Exchange Commission.

Revenue

The primary drivers of our increase in revenues relates to revenue from recent acquisitions, new contract awards and growth on certain existing contracts. These increases were offset by contracts and tasks that ended and reduced scope of work on some contracts.

Cost of services

The increase in cost of services was primarily due to increases in revenue and the reclassification of certain allocated indirect expenses. As a percentage of revenue, direct labor costs was 49% for both the three months ended June 30, 2021 and 2020. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, were 36% and 37% for the three months ended June 30, 2021 and 2020, respectively. With COVID mitigation protocols being reduced or lifted, direct labor has been impacted as employees have begun utilizing paid time off at a normalized level.

General and administrative expenses

The decrease in general and administrative expenses was primarily due to changes in the classification of certain indirect cost allocations of approximately $4 million, reduced bad debt expense and other indirect expenditures. These reductions were partially offset by increased expenditures for bid and proposal and investments in new capabilities through research and development expenditures.

Interest expense

The decrease in interest expense was related to lower average outstanding borrowings on our revolving credit facility.

Provision for income taxes

Our effective tax rate is affected by recurring items, such as the relative amount of income we earn in various taxing jurisdictions and their tax rates. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rate was 24% and 23% for the three months ended June 30, 2021 and 2020, respectively. For the three months ending June 30, 2021, the effective tax rate increased primarily due to the increase in the
20


market value of our deferred compensation plan during the second quarter of 2020.
