NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2012

UNAUDITED

1. Introduction and Overview

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the Departments of Defense, including health organizations, State, Homeland Security, Energy and Justice, including the Federal Bureau of Investigation (FBI); the space community; and other U.S. federal government customers. We provide support to critical national security programs for federal agencies through approximately 1,000 current contracts. Our services include the following solution sets that are aligned with the long-term needs of our national security clients: command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) lifecycle support; cyber security; global logistics support; intelligence/counter-intelligence support; information technology (IT) modernization and sustainment; systems engineering; test and evaluation; and health IT. We support major national missions, such as military readiness, terrorist threat detection, information security and border protection. Our employees operate primarily in the United States, as well as in numerous locations internationally.

2. Basis of Presentation

The accompanying unaudited 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 United States of America, have been condensed or omitted pursuant to those rules and regulations. We recommend that you read these unaudited 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, 2011, previously filed with the SEC. We believe that the unaudited 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.

3. Acquisitions

Our acquisitions have been accounted for using the acquisition method of accounting under the Accounting Standards Codification (ASC) 805, Business Combination.

HBGary, Inc.-On April 2, 2012, we completed the acquisition of certain assets of HBGary, Inc. (HBGary). The acquisition was completed through an asset purchase agreement dated February 27, 2012, by and among a subsidiary of ManTech International Corporation, HBGary and the shareholders of HBGary.

HBGary provides a comprehensive suite of software products to detect, analyze and diagnose Advance Persistent Threats and targeted malware. The company has customers in the financial services, energy, critical infrastructure and technology sectors.

This acquisition broadened our cyber security solution capability for customers.

ManTech funded the acquisition with cash on hand. The preliminary purchase price was $23.7 million and may increase or decrease depending on the finalization of the post-closing working capital adjustment. The asset purchase agreement did not contain provisions for contingent consideration. Pursuant to the asset purchase agreement, $4.8 million was placed into an escrow account to satisfy potential indemnification liabilities of HBGary. The escrow period will expire 18 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $4.8 million.

During 2012, ManTech incurred approximately $0.5 million of acquisition related costs related to the HBGary transaction. These costs are included in the general and administrative expense in our consolidated statement of income for the three and six months ended June 30, 2012.

The preliminary purchase price of $23.7 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The following information represents the preliminary purchase price allocation, as we are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price. Total assets were $24.3 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $0.6 million. Included in total assets were $3.1 million in acquisition related intangible assets. We recorded goodwill of $19.8 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for companies providing cyber service and product solutions to both federal and commercial customers.

7

The components of other intangible assets associated with the acquisition were developed technology, customer relationships and trademark valued at $2.0 million, $0.9 million and $0.2 million, respectively. Developed technology represents the software developed by HBGary to detect, analyze and diagnose Advanced Persistent Threats and targeted malware. Customer relationships represent the underlying relationship with HBGary customers in the financial services, energy, critical infrastructure and technology sectors. Trademark represents the HBGary trade name that is recognized in the industry. These intangible assets are being amortized straight-line over their estimated useful lives of 2 years. The weighted-average amortization period for the intangible assets is 2 years.

Evolvent Technologies, Inc.-On January 6, 2012, we completed the acquisition of Evolvent Technologies, Inc. (Evolvent). The results of Evolvent's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an equity purchase agreement dated January 6, 2012, by and among ManTech, shareholders and warrantholders of Evolvent, and its parent, and Prudent Management, LLC in its capacity as the sellers' representative.

Evolvent provides services in clinical IT, clinical business intelligence, imaging cyber security, behavioral health, tele-health, software development and systems integration. Its systems and processes enable better decision-making at the point of care and full integration of medical information across different platforms. At January 6, 2012, Evolvent had 189 employees.

This acquisition has enabled ManTech to expand its customer relationships and deliver IT solutions through Evolvent's existing relationships with the Department of Defense health organizations, the Veterans Administration and the Department of Health and Human Services.

ManTech funded the acquisition with cash on hand. The preliminary purchase price was $39.0 million and may increase or decrease depending on the finalization of post-closing working capital adjustments. The equity purchase agreement did not contain provisions for contingent consideration. Pursuant to the equity purchase agreement, $8.0 million was placed into an escrow account to satisfy potential indemnification liabilities of Evolvent. The escrow period will expire 36 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $8.0 million.

During the six months ended June 30, 2012, the Company incurred $0.2 million of acquisition costs. These costs are included in general and administrative expense in our income statement.

The preliminary purchase price of $39.0 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The following information represents the preliminary purchase price allocation, as we are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price. Total assets were $46.0 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $7.0 million. Included in total assets were $3.7 million in acquisition related intangible assets. We recorded goodwill of $33.2 million, which is not deductible for tax purposes. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies providing IT services and solutions to the federal government healthcare sector.

In allocating the preliminary purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of Evolvent's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $3.4 million and $0.3 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with Evolvent's existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 18.5 years.

Worldwide Information Network Systems, Inc.-On November 15, 2011, we completed the acquisition of Worldwide Information Network Systems, Inc. (WINS). The results of WINS' operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated October 26, 2011, by and among a subsidiary of ManTech International Corporation, WINS and its sole shareholder.

WINS is a provider of IT solutions with network engineering and cyber security technical expertise to the Department of Defense, Department of State and other agencies. WINS' largest customer is the Defense Intelligence Agency (DIA) through its prime position on the Solutions for the Information Technologies Enterprise (SITE) Indefinite Delivery/Indefinite Quantity contract vehicle. At November 15, 2011, WINS had 199 employees of which 96% held security clearances.

This acquisition broadened our footprint in the high-end defense and intelligence markets. The addition of WINS' IT capabilities, and its prime position on the DIA SITE contracts, support of the state department and other contracts will enhance our positioning with important customers and further our growth prospects.

ManTech funded the acquisition with cash on hand. The purchase price was $90.4 million. The stock purchase agreement did not contain provisions for contingent consideration. Pursuant to the stock purchase agreement, $9.0 million was placed into an escrow account to satisfy potential indemnification liabilities of WINS. The escrow period will expire 18 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $9.0 million.

The purchase price of $90.4 million was allocated to the underlying assets and liabilities based on their fair value at the date

8

of acquisition. Total assets were $100.5 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $10.1 million. Included in total assets were $18.7 million in acquisition related intangible assets. We recorded goodwill of $62.5 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies supporting high-end defense, intelligence and homeland security markets.

In allocating the purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of WINS' contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $18.0 million and $0.7 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with WINS' existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 19.3 years.

TranTech, Inc.-On February 11, 2011, we completed the acquisition of TranTech, Inc. (TranTech). The results of TranTech’s operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 11, 2011, by and among ManTech International Corporation, TranTech and its sole shareholder.

TranTech provides information technology, network and cyber security services to the federal government. At February 11, 2011, TranTech had 57 employees.

The acquisition allowed us to continue extending our presence in the defense, security and intelligence communities, and to offer comprehensive solutions through a prime position on the Defense Information Systems Agency ENCORE II contract.

During the six months ended June 30, 2011, the Company incurred $0.3 million of acquisition costs. These costs are included in general and administrative expense in our income statement.

ManTech funded the acquisition with cash on hand. The purchase price of $21.5 million was allocated to the underlying assets and liabilities based on their fair values at the date of acquisition. Total assets were $23.8 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $2.3 million. Included in total assets were $5.0 million in acquisition related intangible assets. We recorded goodwill of $14.6 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies supporting high-end defense, intelligence and homeland security markets.

In allocating the purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of TranTech's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $4.6 million and $0.4 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with TranTech's existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 18.5 years.

4. 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 the Company’s 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, 2012, we declared and paid two dividends of $0.21 per share on both classes of common stock. For the same period in 2011, we declared and paid a dividend of $0.42 per share 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 has 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.

9

The weighted average number of common shares outstanding is computed as follows (in thousands):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Numerator for net income per Class A and Class B common stock:
Distributed earnings	$	7,756	$	15,413	$	15,501	$	15,413
Undistributed earnings	16,989		21,029		34,886		52,932
Net income	$	24,745	$	36,442	$	50,387	$	68,345
Numerator for basic net income Class A common stock	$	15,896	$	23,238	$	32,354	$	43,529
Numerator for basic net income Class B common stock	$	8,849	$	13,204	$	18,033	$	24,816
Numerator for diluted net income Class A common stock	$	15,905	$	23,293	$	32,381	$	43,632
Numerator for diluted net income Class B common stock	$	8,840	$	13,149	$	18,006	$	24,713
Basic weighted average common shares outstanding
Class A common stock	23,697		23,357		23,670		23,282
Class B common stock	13,193		13,271		13,193		13,273
Effect of potential exercise of stock options
Class A common stock	39		153		56		152
Class B common stock	—		—		—		—
Diluted weighted average common shares outstanding - Class A	23,736		23,510		23,726		23,434
Diluted weighted average common shares outstanding - Class B	13,193		13,271		13,193		13,273

For the three months ended June 30, 2012 and 2011, options to purchase 3.0 million and 2.1 million 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, 2012 and 2011, options to purchase 2.9 million and 2.0 million 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, 2012 and 2011, shares issued from the exercise of stock option were 37 thousand and 220 thousand, respectively.

5. Receivables

We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. The components of contract receivables are as follows (in thousands):

	June 30, 2012			December 31, 2011
Billed receivables	$	401,478		$	422,954
Unbilled receivables:
Amounts billable	109,171			101,997
Revenues recorded in excess of funding	13,033			19,982
Retainage	7,603			5,264
Allowance for doubtful accounts	(10,176		)	(9,729		)
Total receivables, net	$	521,109		$	540,468

Amounts billable consist principally of amounts to be billed within the next month. Revenues recorded in excess of funding are billable upon receipt of contractual amendments or other modifications. The retainage is billable upon completion of the contract performance and approval of final indirect expense rates by the government. Accounts receivable at June 30, 2012, are expected to be substantially collected within one year except for approximately $1.5 million, of which amount 90.0% is related

10

to receivables from direct sales to the U.S. government. The remainder is related to receivables from contracts in which we acted as a subcontractor to other contractors.

The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts are primarily due from the U.S. government. The allowance for doubtful accounts represents the Company’s exposure to compliance issues, contractual issues and bad debt related to prime contractors.

6. Property and Equipment

Major classes of property and equipment are summarized as follows (in thousands):

	June 30, 2012			December 31, 2011

7. Goodwill and Other Intangibles

Under ASC 350, Intangibles - Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. We have elected to perform this review during the second quarter of each calendar year. The goodwill impairment test is a two-step process performed at the reporting unit level. If the first step of the impairment test does not indicate an impairment, performance of the second step is not required. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach.

The income approach is a valuation technique in which fair value is based from forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital.

The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors.

The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors.

To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization). We compared our implied control premium to the control premiums in comparable transactions to assess the reasonableness of our calculations. Based on this comparison the implied control premium appeared reasonable.

During the second quarter of 2012, we completed our annual goodwill impairment test. During the second quarter of 2012, our market capitalization declined below our carrying value. The results of step one of this test showed the fair value of all reporting units were substantially in excess of their carrying value, therefore, no impairment losses were identified and performance of step two was not required. We continue to monitor events that could impact our financial outlook and our assets including potential significant reductions in government spending that could adversely impact our financial results and changes in market conditions that could result in a reduction in the fair value of our assets.

Revolving credit facility	$	—	$	—
7.25% senior unsecured notes	200,000		200,000
Long-term debt	$	200,000	$	200,000

Revolving Credit Facility-We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A, as administrative agent. The credit agreement provides for a $500.0 million revolving credit facility, with a $25.0 million letter of credit sublimit and a $30.0 million swing line loan sublimit. The credit agreement also contains an accordion feature that permits the Company to arrange with the lenders for the provision of up to $250.0 million in additional commitments. The maturity date for the credit agreement is October 12, 2016.

Borrowings under the credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market-rate spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's 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 the Company to comply with specified financial covenants, including the maintenance of certain leverage ratios and a certain fixed charge 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 additional actions. As of June 30, 2012, we were in compliance with our financial covenants under the credit agreement.

We had no outstanding balance on our credit facility at June 30, 2012 and December 31, 2011. The maximum additional available borrowing under the credit facility at June 30, 2012 was $498.9 million. As of June 30, 2012, we were contingently liable under letters of credit totaling $1.1 million, which reduced our availability to borrow under our credit facility.

The following table summarizes the activity under our revolving credit facility for the six months ended June 30, 2012 and 2011 (in thousands):

	Six months ended June 30,
	2012			2011
Borrowing under revolving credit facility	$	9,000		—
Repayment of borrowings under revolving credit facility	$	(9,000	)	—

7.25% Senior Unsecured Notes-Effective April 13, 2010, the Company issued $200.0 million of 7.25% senior unsecured notes in a private placement that were resold inside the United States to qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, and outside the United States to non-U.S. persons in reliance on Regulation S under the Securities Act of 1933. A portion of the proceeds was used to pay down the balance on our prior revolving credit facility incurred to pay for the Sensor Technologies Inc. acquisition.

Pursuant to the terms of a registration rights agreement entered into in connection with the issuance of the 7.25% senior unsecured notes, on August 19, 2010, ManTech completed the exchange of $200.0 million in aggregate principal amount of 7.25% senior unsecured notes due 2018 that are registered under the Securities Act of 1933, as amended, for all of the then outstanding unregistered 7.25% senior unsecured notes due 2018.

The 7.25% senior unsecured notes mature on April 15, 2018 with interest payable semi-annually starting on October 15, 2010. The 7.25% senior unsecured notes were issued at 100% of the aggregate principal amount and are effectively subordinate to the Company’s existing and future senior secured debt (to the extent of the value of the assets securing such debt), including debt outstanding under our revolving credit facility. The 7.25% senior unsecured notes may be redeemed, in whole or in part, at any time, at the option of the Company, subject to certain conditions specified in the indenture governing the 7.25% senior unsecured notes. The 7.25% senior unsecured notes are guaranteed, jointly and severally, on a senior unsecured basis by each of our wholly-

13

owned domestic subsidiaries that also guaranteed debt obligations under our prior revolving credit facility or will guarantee debt obligations under our revolving credit facility.

The fair value of the 7.25% senior unsecured notes as of June 30, 2012 was approximately $210.0 million based on quoted market prices.

The Company incurred approximately $4.9 million in issuance costs, which are being amortized to interest expense over the contractual life of the 7.25% senior unsecured notes using the effective interest rate method, resulting in an effective rate of 7.67%.

The indenture governing the 7.25% senior unsecured notes contains customary events of default, as well as restrictive covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and allow to exist certain control provisions. An event of default under the indenture will allow either the trustee of the notes or the holders of at least 25% in principal amount of the then outstanding notes to accelerate, or in certain cases, will automatically cause the acceleration of, the amounts due under the notes. As of June 30, 2012, the Company was in compliance with all required covenants under the indenture.

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 the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the Company, whether related to the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayment, fines or penalties being imposed upon the Company, 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 (DCAA) has completed our incurred cost audits through 2002 and the majority of audits for 2003, 2004 and 2005, which resulted in no material adjustments. The remaining audits for 2003 through 2011 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.

10. Stock-Based Compensation

In May 2011, the Company’s stockholders approved our 2011 Management Incentive Plan (the Plan), which was designed to enable us to attract, retain and motivate key employees. Awards granted under the Plan are settled in shares of Class A common stock. The 2011 restatement of the Plan increased the base number of shares of our Class A common stock reserved for issuance by 1,500,000 shares. 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 31^st of the previous year. On January 3, 2012, 552,466 additional shares were made available for issuance under the Plan. Through June 30, 2012, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 3,392,984. Through June 30, 2012, 4,437,815 shares of our Class A common stock have been issued as a result of the exercise of options granted under the Plan. The Plan expires in May 2021.

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, 2012 and 2011, we recorded $2.0 million and $2.3 million of stock-based compensation cost, respectively. For the six months ended June 30, 2012 and 2011, we recorded $4.4 million and $4.5 million of stock based compensation cost, respectively. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the six months ended June 30, 2012 and 2011, the total recognized tax (deficiency) benefit from the exercise of stock options, vested cancellations and the vesting of restricted stock was $(0.3) million and less than $0.1 million, respectively.

Stock Options-We typically issue options that vest in three equal installments, beginning on the first anniversary of the date of grant. Under the terms of the Plan, the contractual life of the option grants may not exceed eight years. During the six months ended June 30, 2012 and 2011, we issued options that expire five years from the date of grant.

Fair Value Determination-We have used the Black-Scholes-Merton option pricing model to determine fair value of our

14

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.

The following weighted-average assumptions were used for option grants during the six months ended June 30, 2012 and 2011:

Volatility-The expected volatility of the options granted was estimated based upon historical volatility of the Company’s share price through weekly observations of the Company’s trading history.

Expected Term-The expected term of options granted to employees during the six months ended June 30, 2012 and 2011 was determined from historical exercises of the grantee population. For all grants valued during the six months ended June 30, 2012 and 2011, the options had graded vesting over three years (33.3% of the options vest annually) and a contractual term of five years.

Risk-free Interest Rate-The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.

Dividend Yield-The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  In the second quarter of 2011, we initiated a regular cash dividend program. We have calculated our expected dividend yield based on an expected cash dividend of $0.84 per share per year.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the six months ended June 30, 2012 and 2011:

	Six months ended
	June 30,
	2012		2011
Volatility	30.49	%	36.00	%
Expected life of options (in years)	3.04		2.95
Risk-free interest rate	0.56	%	1.06	%
Dividend yield	2.25	%	—	%

Stock Option Activity-During the six months ended June 30, 2012, we granted stock options to purchase 400,950 shares of Class A common stock at a weighted-average exercise price of $33.73 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the six months ended June 30, 2012 and 2011, as determined under the Black-Scholes-Merton valuation model, was $5.98 and $10.57, respectively. These options vest in three equal installments over three years and have a contractual term of five years. Option grants that vested during the six months ended June 30, 2012 and 2011 had a combined fair value of $5.5 million and $4.8 million, respectively.

The following table includes information with respect to stock option activity and stock options outstanding for the year ended December 31, 2011 and the six months ended June 30, 2012:

Stock options expected to vest	1,328,497	3.8	$	38.84	$	—
Options exercisable and expected to vest	2,907,984

Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2012 was $8.8 million, which is expected to be recognized over a weighted-average period of 1.8 years and will be adjusted for any future changes in estimated forfeitures.

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 shares issued to employees vest over three years in one-third increments on the first, second and third anniversaries of the grant date, contingent upon employment with the Company on the vesting dates. Restricted shares issued to members of our Board of Directors vest in one year. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest.

Restricted Stock Activity-The following table summarizes the restricted stock activity for the year ended December 31, 2011 and the six months ended June 30, 2012:

11. Business Segment and Geographic Area Information

We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. Our federal government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly,

16

or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. Revenues from the U.S. government under prime contracts and subcontracts were approximately 99.2% and 99.1% of our total revenues for the six months ended June 30, 2012 and 2011, respectively. There were no sales to any customers within a single country (except for the United States) where the sales accounted for 10% or more of total revenues. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. Substantially all assets of continuing operations were held in the United States for the periods ended June 30, 2012 and December 31, 2011. Revenues by geographic customer and the related percentages of total revenues for the three and six months ended June 30, 2012 and 2011 were as follows (dollars in thousands):

12. Sale of Investment

ManTech received approximately $3.2 million in proceeds on April 8, 2011 and an additional $0.2 million was received in the second quarter of 2012 for the sale of our investment of less than 5% in NetWitness Corporation (NetWitness). At June 30, 2012, $0.3 million was held in escrow to be distributed no later than December 15, 2012, subject to any then unresolved indemnity claims. The transaction was consummated on April 1, 2011 pursuant to an agreement and plan of merger dated March 12, 2011 by and among EMC Corporation, NetWitness, and certain persons acting as the representative for the shareholders of NetWitness. The sale of our investment resulted in a pre-tax gain of approximately $3.7 million, which was recorded in other income in the Company's statement of income for the six months ended June 30, 2011.

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

• adverse changes in U.S. government spending priorities due to budgetary constraints affecting federal government spending generally or other factors;

• failure to retain existing U.S. government contracts, win new contracts or win recompetes;

• adverse changes in future levels of expenditures for programs we support caused by budgetary pressures facing the federal government and changing mission priorities;

• adverse changes in our mix of contract types;

• failure to obtain option awards, task orders or funding under contracts;

• adverse results of U.S. government audits of our government contracts;

• risk of contract renegotiation, performance, modification or termination;

• risks associated with complex U.S. government procurement laws and regulations;

• competition;

• risks of financing, such as increases in interest rates and restrictions imposed by our outstanding indebtedness, including the ability to meet financial covenants, and risks related to an ability to obtain new or additional financing;

• failure to successfully integrate recently acquired companies or businesses into our operations or realize any accretive or synergistic effects from such acquisitions;

• failure to identify, execute or effectively integrate future acquisitions; and

• failure to maintain strong relationships with other contractors.

We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report. These and other risk factors are more fully described and discussed in the section titled “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011 and under Item 1A. of Part II of our Quarterly Reports on Form 10-Q, and from time to time, in our other filings with the Securities and Exchange Commission (SEC). We undertake no obligation to revise or update any forward-looking statements in order to reflect any event or circumstance that may arise after the date of this Quarterly Report. We also suggest that you carefully review and consider the various disclosures made in this Quarterly Report that attempt to advise interested parties of the risks and factors that may affect our business, financial condition, results of operations and prospects.

Introduction and Overview

ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, including health organizations, State, Homeland Security, Energy and Justice, including the Federal Bureau of Investigations (FBI); the space community; and other U.S. federal government customers. We combine deep domain understanding and technical capability to deliver comprehensive information technology, systems engineering, technical and other services and solutions primarily in support of mission critical national security programs for the intelligence community and Department of Defense. We provide support to critical national security programs for federal agencies through approximately 1,000 current contracts. Our broad set of services is generally deployed in custom combinations to best address the requirements of our customers' long-term programs. Our services generally include the following solution sets that

19

are aligned with the long-term needs of our national security clients: command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) lifecycle support; cyber security; global logistics support; intelligence/counter-intelligence support; information technology modernization and sustainment; systems engineering; test and evaluation; and health IT. ManTech supports major national missions, such as military readiness, terrorist threat detection, information security and border protection.

We derive revenues primarily from contracts with U.S. government agencies that are focused on national security, and as a result, funding for our programs is generally linked to trends in U.S. government spending in areas such as defense, intelligence, homeland security, state, justice and FBI. As it relates to evolving terrorist threats and world events, the U.S. government has continued to increase its defense, intelligence and homeland security budgets. However, this trend may not continue due to changing mission priorities, the mounting deficit of the U.S. government and public pressure to reduce U.S. government spending, which could result in significant impacts to programs across the defense industry.

We recommend that you read this discussion and analysis in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, previously filed with the SEC.

Revenues

Revenues decreased 15.1% to $638.9 million for the three months ended June 30, 2012, compared to $752.7 million for the same period in 2011. The primary driver of our decrease in revenues relates to reductions on our C4ISR support contracts primiarly related to other direct costs and subcontractors. These reductions were partially offset by the revenues provided from our recent acquisitions, a contract to provide mobile telecommunication services in Afghanistan and organic growth on our cyber related contracts. The reduction in C4ISR work is primarily due to changing customer mission priorities, including the withdrawal of U.S. troops from Iraq in 2011, reduced demand for field service support and delays in enhancements to existing ISR systems.

Cost of services

Cost of services decreased 15.6% to $544.1 million for the three months ended June 30, 2012, compared to $644.6 million for the same period in 2011. The decrease in cost of services is primarily due to a decrease in subcontractor labor and material costs related to the reduction in revenues. As a percentage of revenues, cost of services decreased to 85.2% for the three months ended June 30, 2012 as compared to 85.6% for the same period in 2011. Direct labor costs, which include applicable fringe benefits and overhead, decreased 5.6% for the three months ended June 30, 2012 over the same period in 2011. As a percentage of revenues, direct labor costs increased to 37.8% for the three months ended June 30, 2012, compared to 34.0% for the same period in 2011.

20

Other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, decreased by 22.2% for the three months ended June 30, 2012 over the same period in 2011. As a percentage of revenues, other direct costs decreased from 51.6% for the three months ended June 30, 2011 to 47.4% for the same period in 2012.

General and administrative expenses

General and administrative expenses increased to $49.9 million for the three months ended June 30, 2012, compared to $48.9 million for the same period in 2011. The increase was primarily due to our acquisitions. As a percentage of revenues, general and administrative expenses was 7.8% and 6.5% for the three months ended June 30, 2012 and 2011, respectively.

Other income (expense), net

Other income (expense), net was $(0.1) million for the three months ended June 30, 2012, compare to $3.8 million for the same period in 2011. During the three months ended June 30, 2011, we recorded a gain of $3.7 million on the sale of our investment in NetWitness Corporation.

Provision for income taxes

The provision for income taxes decreased to $16.1 million for the three months ended June 30, 2012, compared to $22.6 million for the same period in 2011. Our effective tax rates were 39.4% and 38.3% for the three months ended June 30, 2012 and 2011, respectively. The increase in our effective tax rate was primarily attributable to a lower utilization of tax credits.

Net income

Net income decreased 32.1% to $24.7 million for the three months ended June 30, 2012, compared to $36.4 million for the same period in 2011. The decrease in net income was due to lower revenues, offset by lower cost of services and provision for income taxes.

Six Months Ended June 30, 2012 Compared to the Six Months Ended June 30, 2011

The following table sets forth certain items from our condensed consolidated statement of income and the relative percentage that certain items of expenses and earnings bear to revenues, as well as the period-to-period change from June 30, 2011 to June 30, 2012.

	Six months ended June 30,										Period-to-Period Change

NET INCOME	$	50,387		$	68,345		3.8	%	4.7	%	$	(17,958	)	(26.3	)%

Revenues

Revenues decreased 9.5% to $1,315.4 million for the six months ended June 30, 2012, compared to $1,453.5 million for the same period in 2011. The primary driver of our decrease in revenues relates to reductions on our C4ISR support contracts. These reductions were partially offset by the revenues provided from our recent acquisitions, a contract to provide mobile telecommunication services in Afghanistan and organic growth on our cyber related contracts.

The reduction in C4ISR work is primarily due to changing customer mission priorities, including the withdrawal of U.S. troops from Iraq in 2011, reduced demand for field service support and delays in enhancements to existing ISR systems. We expect the change in U.S. government spending priorities to continue, as evidenced by the planned withdrawal from Afghanistan

21

and the projected defense budget cuts laid out in the President's Defense Strategic Review. In addition, we have experienced a trend towards more cost-reimbursable contract awards and have experienced increased pricing pressure as a result of certain agencies placing increased importance on the lowest price of services provided as opposed to the technical superiority of the offering. Cost-reimbursable contracts generally produce a lower fee than we earn on other contract types. We expect revenues in the second half of 2012 to increase as compared to the first half of 2012 as a result of growth in the areas of cyber security; intelligence/counter-intelligence support; and health care information technology. We anticipate flat or slightly declining revenues from Overseas Contingency Operations related to global logistics support and C4ISR support.

Cost of services

Cost of services decreased 9.4% to $1,127.0 million for the six months ended June 30, 2012, compared to $1,244.4 million for the same period in 2011. The decrease in cost of services is primarily due to a decrease in subcontractor labor and material costs related to the decrease in revenues As a percentage of revenues, cost of services remained stable at 85.7% for the six months ended June 30, 2012 as compared to 85.6% for the same period in 2011. Direct labor costs, which include applicable fringe benefits and overhead, decreased 6.2% for the six months ended June 30, 2012 over the same period in 2011. As a percentage of revenues, direct labor costs increased to 36.7% for the six months ended June 30, 2012, compared to 35.4% for the same period in 2011. Other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, decreased by 11.7% for the six months ended June 30, 2012 over the same period in 2011. As a percentage of revenues, other direct costs decreased from 50.2% for the six months ended June 30, 2011 to 49.0% for the same period in 2012.

General and administrative expenses

General and administrative expenses increased to $97.9 million for the six months ended June 30, 2012, compared to $94.1 million for the same period in 2011. The increase was primarily due to our acquisitions. As a percentage of revenues, general and administrative expenses was 7.4% and 6.5% for the six months ended June 30, 2012 and 2011, respectively. Over time we expect general and administrative expenses as a percentage of revenues to trend towards 2011 levels.

Other income (expense), net

Other income (expenses), net was $(0.1) million for the six months ended June 30, 2012, compared to $3.9 million for the same period in 2011. During the six months ended June 30, 2011, the sale of Net Witness investment resulted in a gain of $3.7 million.

Provision for income taxes

The provision for income taxes decreased to $32.1 million for the six months ended June 30, 2012, compared to $42.8 million for the same period in 2011. Our effective tax rates were 38.9% and 38.5% for the six months ended June 30, 2012 and 2011, respectively. The increase in our effective tax rate was primarily attributable to a lower utilization of tax credits.

Net income

Net income decreased 26.3% to $50.4 million for the six months ended June 30, 2012, compared to $68.3 million for the same period in 2011. The decrease in net income was due to lower revenues, offset by lower cost of services and provision for income taxes.

Backlog

At June 30, 2012 and December 31, 2011, our backlog was $4.0 billion and $4.7 billion, respectively, of which $1.4 billion and $1.3 billion, respectively, was funded backlog. Backlog represents estimates that we calculate on a consistent basis. For additional information on how we compute backlog, see our annual report on Form 10-K for the fiscal year ended December 31, 2011, previously filed with the SEC.

Effects of Inflation

Inflation and uncertainties in the macroeconomic environment, such as conditions in the financial markets, could impact our labor rates beyond the predetermined escalation factors. However, we generally have been able to price our contracts in a manner to accommodate the rates of inflation experienced in recent years. Under our time and materials contracts, labor rates are usually adjusted annually by predetermined escalation factors. Our cost reimbursable contracts automatically adjust for changes in cost. Under our fixed-price contracts, we include a predetermined escalation factor, and generally, we have not been adversely affected by near-term inflation. Purchases of equipment and materials directly for contracts are usually cost reimbursable.

Liquidity and Capital Resources

Historically, our primary liquidity needs have been the financing of acquisitions, working capital and capital expenditures. Our primary sources of liquidity are cash provided by operations and our revolving credit facility. On June 30, 2012, the Company's cash and cash equivalents balance was $124.7 million. At June 30, 2012, we had no outstanding borrowings under our revolving

22

credit facility. At June 30, 2012, we were contingently liable under letters of credit totaling $1.1 million, which reduced our ability to borrow under our credit facility. The maximum available borrowing under our credit facility at June 30, 2012 was $498.9 million. At June 30, 2012, we had $200.0 million outstanding of our 7.25% senior unsecured notes due April 2018. For additional information concerning our 7.25% senior unsecured notes, see Note 8 to our consolidated financial statements in Item 1.

Generally, cash provided by operating activities is adequate to fund our operations. Due to fluctuations in our cash flows and level of operations, it is necessary from time to time to increase borrowings under our credit facility to meet cash demands.

Cash flows from operating activities

	Six months ended June 30,
	2012		2011
	(in thousands)
Net cash flow from operating activities	$	90,847	$	186,728

Our operating cash flows are primarily affected by the overall profitability of our contracts, our ability to invoice and collect from our clients in a timely manner and our ability to manage our vendor payments. We bill most of our customers monthly after services are rendered. Decreased cash flows from operations during the six months ended June 30, 2012 compared to the same period in 2011 were due to decreased billings in excess of revenue earned and the timing of payment of vendors and accrued salaries, offset by the timing of collection of our receivables and depreciation expense. The decrease in billing in excess of revenue earned and the increase in depreciation expense were primarily related to a contract to provide mobile telecommunication services in Afghanistan. Our accounts receivable days sales outstanding (DSO) was 73 and 65 for the period ended June 30, 2012 and 2011, respectively.

Cash flows from investing activities

	Six months ended June 30,
	2012			2011
	(in thousands)
Net cash flow from investing activities	$	(66,335	)	$	(56,283	)

Our cash flows from investing activities consist primarily of business acquisitions, expenditures for equipment, leasehold improvements and software. Cash outflows during the six months ended June 30, 2012 were due to the acquisition of HBGary for $23.8 million and Evolvent for $38.0 million net of cash acquired and capital expenditures of $6.1 million, offset by cash received from a disposition. Cash outflows during the six months ended June 30, 2011 were due to capital expenditures of $39.2 million primarily related to a mobile telecommunication network build out and the acquisition of TranTech for $20.2 million net of cash acquired, offset by $3.2 million in cash proceeds from the sale of an investment.

Cash flows from financing activities

	Six months ended June 30,
	2012			2011
	(in thousands)
Net cash flow from financing activities	$	(14,334	)	$	(8,324	)

Cash outflows from financing activities during the six months ended June 30, 2012 resulted primarily from the dividends paid of $15.5 million, offset by the proceeds from the exercise of stock options for $1.1 million. Cash outflows from financing during the six months ended June 30, 2011 resulted primarily from the dividends paid for $15.4 million, offset by the proceeds from the exercise of stock options for $6.9 million.

Capital Resources

We believe the capital resources available to us from our cash on hand of $124.7 million at June 30, 2012 and under our revolving credit facility, with the ability to borrow up to $500.0 million, and cash from our operations are adequate to fund anticipated cash requirements for at least the next twelve months. We anticipate financing our external growth from acquisitions and our longer-term internal growth through one or more of the following sources: cash from operations, use of our revolving

23

facility, additional senior unsecured notes, additional borrowings or issuances of equity. At June 30, 2012, we had no outstanding borrowings under our revolving credit facility. For additional information concerning our revolving credit facility, see Note 8 to our consolidated financial statements in Item 1.

Short-term Borrowings

From time-to-time, we borrow funds against our revolving credit facility for working capital requirements and funding of operations as well as acquisitions. Borrowings under our revolving credit facility bear interest at one of the following variable rate as selected by the Company at the time of the borrowing: a LIBOR based rate plus market spreads (1.25% to 2.25% based on the Company’s consolidated total leverage ratio) or Bank of America’s base rate plus market spreads (0.25% to 1.25% based on the Company’s consolidated total leverage ratio).  In the next twelve months we may use, as needed, our revolving credit facility or additional sources of borrowings in order to fund our anticipated cash requirements.

The following table summarized the activity under our revolving credit facility for the six months ended June 30, 2012 and 2011 (in thousands):

	Six months ended June 30,
	2012			2011
Borrowing under revolving credit facility	$	9,000		$	—
Repayment of borrowings under revolving credit facility	$	(9,000	)	$	—

Cash Management

To the extent possible, we invest our available cash in short-term, investment grade securities in accordance with our investment policy. Under our investment policy, we manage our investments in accordance with the priorities of maintaining the safety of our principal, maintaining the liquidity of our investments, maximizing the yield on our investments and investing our cash to the fullest extent possible. Our investment policy provides that no investment security can have a final maturity that exceeds six months and that the weighted average maturity of the portfolio cannot exceed 60 days. Cash and cash equivalents include cash on hand, amounts due from banks and short-term investments with maturity dates of three months or less at the date of purchase.

Dividend

In May 2012, our Board of Directors declared a quarterly dividend in the amount of $0.21 per share on all issued and outstanding shares of common stock. As a result, dividends in the amount of $7.8 million were paid to our shareholders on June 22, 2012. In February 2012, our Board of Directors declared a quarterly dividend in the amount of $0.21 per share on all issued and outstanding shares of common stock. As a result, dividends in the amount of $7.7 million were paid to our shareholders on March 23, 2012. We expect to continue our regular dividend program; however, all future declarations of dividends will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash requirements, as well as such other factors our Board of Directors deems relevant.

Critical Accounting Estimates and Policies

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions. Application of these policies is particularly important to the portrayal of our financial condition and results of operations. The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates under different assumptions or conditions. Our significant accounting policies, including the critical accounting policies and practices listed below, are more fully described and discussed in the notes to the consolidated financial statements for the fiscal year 2011 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed with the SEC on February 24, 2012.

Revenue Recognition and Cost Estimation

We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable and collectability is reasonably assured. We have a standard internal process that we use to determine whether all required criteria for revenue recognition have been met.

Our revenues consist primarily of services provided by our employees and the pass through of costs for materials and subcontract efforts under contracts with our customers. Cost of services consists primarily of compensation expenses for program personnel, the fringe benefits associated with this compensation and other direct expenses incurred to complete programs, including

24

cost of materials and subcontract efforts.

We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price or time-and-materials contracts. Revenues for cost reimbursement contracts are recorded as reimbursable costs are incurred, including an estimated share of the applicable contractual fees earned. For performance-based fees under cost reimbursable contracts that are subject to the Accounting Standards Codification (ASC) 605-35, Construction-Type and Certain Production-Type Contracts, we recognize the relevant portion of the expected fee to be awarded by the client at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the client regarding performance. For cost reimbursable contracts with performance-based fee incentives that are subject to the provisions of SEC Topic 13, Revenue Recognition, we recognize the relevant portion of the fee upon customer approval. For time-and-material contracts, revenues are recognized to the extent of billable rates times hours delivered plus material and other reimbursable costs incurred. For long-term fixed-price production contracts, revenues are recognized at a rate per unit as the units are delivered, or by other methods to measure services provided. Revenues from other long-term fixed-price contracts is recognized ratably over the contract period or by other appropriate methods to measure services provided. Contract costs are expensed as incurred except for certain limited long-term contracts noted below. For long-term contracts specifically described in the ASC 605-35, we apply the percentage of completion method. Under the percentage of completion method, income is recognized at a consistent profit margin over the period of performance based on estimated profit margins at completion of the contract. This method of accounting requires estimating the total revenues and total contract cost at completion of the contract. During the performance of long-term contracts, these estimates are periodically reviewed and revisions are made as required using the cumulative catch-up method of accounting. The impact on revenue and contract profit as a result of these revisions is included in the periods in which the revisions are made. This method can result in the deferral of costs or the deferral of profit on these contracts. Because we assume the risk of performing a fixed-price contract at a set price, the failure to accurately estimate ultimate costs or to control costs during performance of the work could result, and in some instances has resulted, in reduced profits or losses for such contracts. Both the individual changes in contract estimates and aggregate net changes in the contract estimates recognized using the cumulative catch-up method of accounting were not material to the consolidated statement of operations for all periods presented. Estimated losses on contracts at completion are recognized when identified. In certain circumstances, revenues are recognized when contract amendments have not been finalized.

Accounting for Business Combinations and Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates.

We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value of long-lived assets may not be fully recoverable. We perform this review at the reporting unit level, which is one level below our one reportable segment. The goodwill impairment test is a two-step process performed at the reporting unit level. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). If the first step of the impairment test does not indicate an impairment, performance of the second step is not required.

The fair value of the reporting units are determined based on a weighting of the income approach, market approach and the market transaction approach. The income approach is a valuation technique in which fair value is derived based from forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital. The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors. The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors. To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization). We compared our implied control premium to the control premiums in comparable transactions to assess the reasonableness of our calculations. Based on this comparison the implied control premium appeared reasonable.

25

We have elected to perform our annual review during the second quarter of each calendar year. If any impairment were indicated as a result of a review, we would recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value. No adjustments were necessary as a result of our annual review during the quarter ended June 30, 2012.

Management will continually monitor events that could result in an impairment. Events or circumstances that could cause the fair value of our long-lived assets to decrease include changes in our business environment or market conditions. For example, the U.S. government is currently under pressure to decrease its spending, and reductions across our industry may be mandated in connection with sequestration. The impact of reduced government spending on our programs and industry could materially affect our financial outlook. A significant adverse impact to our financial outlook could result in impairments to our long-term assets, such as goodwill and other intangible assets. Additionally, deteriorating market conditions for comparable public companies in our industry, or a material decline in the market price for the Company's stock, could result in a reduction in the fair value of our assets.

Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of the Company’s recorded goodwill, differences in assumption may have a material effect on the results of the Company’s impairment analysis.

Accounting Standards Updates

Accounting Standards Updates issued but not yet effective are not expected to have a material effect on the Company’s financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risks relates to changes in interest rates for borrowing under our revolving credit facility. At June 30, 2012, we had no outstanding balance on our revolving credit facility. Borrowings under our revolving credit facility bear interest at variable rates. A hypothetical 10% increase in interest rates would increase our annual interest expense for the six months ended June 30, 2012, by less than $0.1 million.

We do not use derivative financial instruments for speculative or trading purposes. When we have excess cash, we invest in short-term, investment grade, interest-bearing securities. Our investments are made in accordance with an investment policy. Under this policy, no investment securities can have maturities exceeding six months and the weighted average maturity of the portfolio cannot exceed 60 days.

Item 4. Controls and Procedures

Management is responsible for establishing and maintaining adequate disclosure controls and procedures. Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Quarterly Report on Form 10-Q, is accurately recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

It should be noted that 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. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. As a result, our disclosure controls and procedures are designed to provide reasonable assurance that such disclosure controls and procedures will meet their objectives.

As of June 30, 2012, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), management evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level described above.

There were no changes in our internal control over financial reporting during the Company’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to certain legal proceedings, government audits, investigations, claims and disputes that arise in the ordinary course of our business. Like most large government defense contractors, our contract costs are audited and reviewed on a continual basis by an in-house staff of auditors from the Defense Contract Auditing Agency. In addition to these routine audits, we are subject from time to time to audits and investigations by other agencies of the federal government. These audits and investigations are conducted to determine if our performance and administration of our government contracts are compliant with contractual requirements and applicable federal statutes and regulations. An audit or investigation may result in a finding that our performance, systems and administration are compliant or, alternatively, may result in the government initiating proceedings against us or our employees, including administrative proceedings seeking repayment of monies, suspension and/or debarment from doing business with the federal government or a particular agency, or civil or criminal proceedings seeking penalties and/or fines. Audits and investigations conducted by the federal government frequently span several years.

Although we cannot predict the outcome of these and other legal proceedings, investigations, claims and disputes, based on the information now available to us, we do not believe the ultimate resolution of these matters, either individually or in the aggregate, will have a material adverse effect on our business, prospects, financial condition, operating results or cash flows.

Item 1A. Risk Factors

There have been no material changes from the risk factors described in the "Risk Factors" section of our Annual Report on the Form 10-K for the year ended December 31, 2011.

Business Acquisition, Entity Acquired and Reason for Acquisition [Abstract]

Acquisitions

Acquisitions

Our acquisitions have been accounted for using the acquisition method of accounting under the Accounting Standards Codification (ASC) 805, Business Combination.

HBGary, Inc.-On April 2, 2012, we completed the acquisition of certain assets of HBGary, Inc. (HBGary). The acquisition was completed through an asset purchase agreement dated February 27, 2012, by and among a subsidiary of ManTech International Corporation, HBGary and the shareholders of HBGary.

HBGary provides a comprehensive suite of software products to detect, analyze and diagnose Advance Persistent Threats and targeted malware. The company has customers in the financial services, energy, critical infrastructure and technology sectors.

This acquisition broadened our cyber security solution capability for customers.

ManTech funded the acquisition with cash on hand. The preliminary purchase price was $23.7 million and may increase or decrease depending on the finalization of the post-closing working capital adjustment. The asset purchase agreement did not contain provisions for contingent consideration. Pursuant to the asset purchase agreement, $4.8 million was placed into an escrow account to satisfy potential indemnification liabilities of HBGary. The escrow period will expire 18 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $4.8 million.

During 2012, ManTech incurred approximately $0.5 million of acquisition related costs related to the HBGary transaction. These costs are included in the general and administrative expense in our consolidated statement of income for the three and six months ended June 30, 2012.

The preliminary purchase price of $23.7 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The following information represents the preliminary purchase price allocation, as we are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price. Total assets were $24.3 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $0.6 million. Included in total assets were $3.1 million in acquisition related intangible assets. We recorded goodwill of $19.8 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for companies providing cyber service and product solutions to both federal and commercial customers.

The components of other intangible assets associated with the acquisition were developed technology, customer relationships and trademark valued at $2.0 million, $0.9 million and $0.2 million, respectively. Developed technology represents the software developed by HBGary to detect, analyze and diagnose Advanced Persistent Threats and targeted malware. Customer relationships represent the underlying relationship with HBGary customers in the financial services, energy, critical infrastructure and technology sectors. Trademark represents the HBGary trade name that is recognized in the industry. These intangible assets are being amortized straight-line over their estimated useful lives of 2 years. The weighted-average amortization period for the intangible assets is 2 years.

Evolvent Technologies, Inc.-On January 6, 2012, we completed the acquisition of Evolvent Technologies, Inc. (Evolvent). The results of Evolvent's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an equity purchase agreement dated January 6, 2012, by and among ManTech, shareholders and warrantholders of Evolvent, and its parent, and Prudent Management, LLC in its capacity as the sellers' representative.

Evolvent provides services in clinical IT, clinical business intelligence, imaging cyber security, behavioral health, tele-health, software development and systems integration. Its systems and processes enable better decision-making at the point of care and full integration of medical information across different platforms. At January 6, 2012, Evolvent had 189 employees.

This acquisition has enabled ManTech to expand its customer relationships and deliver IT solutions through Evolvent's existing relationships with the Department of Defense health organizations, the Veterans Administration and the Department of Health and Human Services.

ManTech funded the acquisition with cash on hand. The preliminary purchase price was $39.0 million and may increase or decrease depending on the finalization of post-closing working capital adjustments. The equity purchase agreement did not contain provisions for contingent consideration. Pursuant to the equity purchase agreement, $8.0 million was placed into an escrow account to satisfy potential indemnification liabilities of Evolvent. The escrow period will expire 36 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $8.0 million.

During the six months ended June 30, 2012, the Company incurred $0.2 million of acquisition costs. These costs are included in general and administrative expense in our income statement.

The preliminary purchase price of $39.0 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. The following information represents the preliminary purchase price allocation, as we are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price. Total assets were $46.0 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $7.0 million. Included in total assets were $3.7 million in acquisition related intangible assets. We recorded goodwill of $33.2 million, which is not deductible for tax purposes. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies providing IT services and solutions to the federal government healthcare sector.

In allocating the preliminary purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of Evolvent's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $3.4 million and $0.3 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with Evolvent's existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 18.5 years.

Worldwide Information Network Systems, Inc.-On November 15, 2011, we completed the acquisition of Worldwide Information Network Systems, Inc. (WINS). The results of WINS' operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated October 26, 2011, by and among a subsidiary of ManTech International Corporation, WINS and its sole shareholder.

WINS is a provider of IT solutions with network engineering and cyber security technical expertise to the Department of Defense, Department of State and other agencies. WINS' largest customer is the Defense Intelligence Agency (DIA) through its prime position on the Solutions for the Information Technologies Enterprise (SITE) Indefinite Delivery/Indefinite Quantity contract vehicle. At November 15, 2011, WINS had 199 employees of which 96% held security clearances.

This acquisition broadened our footprint in the high-end defense and intelligence markets. The addition of WINS' IT capabilities, and its prime position on the DIA SITE contracts, support of the state department and other contracts will enhance our positioning with important customers and further our growth prospects.

ManTech funded the acquisition with cash on hand. The purchase price was $90.4 million. The stock purchase agreement did not contain provisions for contingent consideration. Pursuant to the stock purchase agreement, $9.0 million was placed into an escrow account to satisfy potential indemnification liabilities of WINS. The escrow period will expire 18 months after the purchase closing date. At June 30, 2012, the balance in the escrow account was $9.0 million.

The purchase price of $90.4 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. Total assets were $100.5 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $10.1 million. Included in total assets were $18.7 million in acquisition related intangible assets. We recorded goodwill of $62.5 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies supporting high-end defense, intelligence and homeland security markets.

In allocating the purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of WINS' contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $18.0 million and $0.7 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with WINS' existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 19.3 years.

TranTech, Inc.-On February 11, 2011, we completed the acquisition of TranTech, Inc. (TranTech). The results of TranTech’s operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 11, 2011, by and among ManTech International Corporation, TranTech and its sole shareholder.

TranTech provides information technology, network and cyber security services to the federal government. At February 11, 2011, TranTech had 57 employees.

The acquisition allowed us to continue extending our presence in the defense, security and intelligence communities, and to offer comprehensive solutions through a prime position on the Defense Information Systems Agency ENCORE II contract.

During the six months ended June 30, 2011, the Company incurred $0.3 million of acquisition costs. These costs are included in general and administrative expense in our income statement.

ManTech funded the acquisition with cash on hand. The purchase price of $21.5 million was allocated to the underlying assets and liabilities based on their fair values at the date of acquisition. Total assets were $23.8 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $2.3 million. Included in total assets were $5.0 million in acquisition related intangible assets. We recorded goodwill of $14.6 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for companies supporting high-end defense, intelligence and homeland security markets.

In allocating the purchase price, we consider among other factors, analyses of historical performance and estimates of future performance of TranTech's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $4.6 million and $0.4 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with TranTech's existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 18.5 years.

Business Segment And Geographic Area Information

Business Segment and Geographic Area Information

We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. Our federal government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. Revenues from the U.S. government under prime contracts and subcontracts were approximately 99.2% and 99.1% of our total revenues for the six months ended June 30, 2012 and 2011, respectively. There were no sales to any customers within a single country (except for the United States) where the sales accounted for 10% or more of total revenues. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. Substantially all assets of continuing operations were held in the United States for the periods ended June 30, 2012 and December 31, 2011. Revenues by geographic customer and the related percentages of total revenues for the three and six months ended June 30, 2012 and 2011 were as follows (dollars in thousands):

Sale of Investment

ManTech received approximately $3.2 million in proceeds on April 8, 2011 and an additional $0.2 million was received in the second quarter of 2012 for the sale of our investment of less than 5% in NetWitness Corporation (NetWitness). At June 30, 2012, $0.3 million was held in escrow to be distributed no later than December 15, 2012, subject to any then unresolved indemnity claims. The transaction was consummated on April 1, 2011 pursuant to an agreement and plan of merger dated March 12, 2011 by and among EMC Corporation, NetWitness, and certain persons acting as the representative for the shareholders of NetWitness. The sale of our investment resulted in a pre-tax gain of approximately $3.7 million, which was recorded in other income in the Company's statement of income for the six months ended June 30, 2011.

Allowance for doubtful accounts	(10,176		)	(9,729		)
Total receivables, net	$	521,109		$	540,468

Amounts billable consist principally of amounts to be billed within the next month. Revenues recorded in excess of funding are billable upon receipt of contractual amendments or other modifications. The retainage is billable upon completion of the contract performance and approval of final indirect expense rates by the government. Accounts receivable at June 30, 2012, are expected to be substantially collected within one year except for approximately $1.5 million, of which amount 90.0% is related to receivables from direct sales to the U.S. government. The remainder is related to receivables from contracts in which we acted as a subcontractor to other contractors.

The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts are primarily due from the U.S. government. The allowance for doubtful accounts represents the Company’s exposure to compliance issues, contractual issues and bad debt related to prime contractors.

Commitments And Contingencies

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 the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the Company, whether related to the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayment, fines or penalties being imposed upon the Company, 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 (DCAA) has completed our incurred cost audits through 2002 and the majority of audits for 2003, 2004 and 2005, which resulted in no material adjustments. The remaining audits for 2003 through 2011 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.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill And Other Intangibles

Goodwill and Other Intangibles

Under ASC 350, Intangibles - Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. We have elected to perform this review during the second quarter of each calendar year. The goodwill impairment test is a two-step process performed at the reporting unit level. If the first step of the impairment test does not indicate an impairment, performance of the second step is not required. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach.

The income approach is a valuation technique in which fair value is based from forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital.

The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors.

The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors.

To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization). We compared our implied control premium to the control premiums in comparable transactions to assess the reasonableness of our calculations. Based on this comparison the implied control premium appeared reasonable.

During the second quarter of 2012, we completed our annual goodwill impairment test. During the second quarter of 2012, our market capitalization declined below our carrying value. The results of step one of this test showed the fair value of all reporting units were substantially in excess of their carrying value, therefore, no impairment losses were identified and performance of step two was not required. We continue to monitor events that could impact our financial outlook and our assets including potential significant reductions in government spending that could adversely impact our financial results and changes in market conditions that could result in a reduction in the fair value of our assets.

The changes in the carrying amounts of goodwill during the year ended December 31, 2011 and the period ended June 30, 2012 are as follows (in thousands):

7.25% senior unsecured notes	200,000		200,000
Long-term debt	$	200,000	$	200,000

Revolving Credit Facility-We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A, as administrative agent. The credit agreement provides for a $500.0 million revolving credit facility, with a $25.0 million letter of credit sublimit and a $30.0 million swing line loan sublimit. The credit agreement also contains an accordion feature that permits the Company to arrange with the lenders for the provision of up to $250.0 million in additional commitments. The maturity date for the credit agreement is October 12, 2016.

Borrowings under the credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market-rate spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's 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 the Company to comply with specified financial covenants, including the maintenance of certain leverage ratios and a certain fixed charge 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 additional actions. As of June 30, 2012, we were in compliance with our financial covenants under the credit agreement.

We had no outstanding balance on our credit facility at June 30, 2012 and December 31, 2011. The maximum additional available borrowing under the credit facility at June 30, 2012 was $498.9 million. As of June 30, 2012, we were contingently liable under letters of credit totaling $1.1 million, which reduced our availability to borrow under our credit facility.

The following table summarizes the activity under our revolving credit facility for the six months ended June 30, 2012 and 2011 (in thousands):

7.25% Senior Unsecured Notes-Effective April 13, 2010, the Company issued $200.0 million of 7.25% senior unsecured notes in a private placement that were resold inside the United States to qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, and outside the United States to non-U.S. persons in reliance on Regulation S under the Securities Act of 1933. A portion of the proceeds was used to pay down the balance on our prior revolving credit facility incurred to pay for the Sensor Technologies Inc. acquisition.

Pursuant to the terms of a registration rights agreement entered into in connection with the issuance of the 7.25% senior unsecured notes, on August 19, 2010, ManTech completed the exchange of $200.0 million in aggregate principal amount of 7.25% senior unsecured notes due 2018 that are registered under the Securities Act of 1933, as amended, for all of the then outstanding unregistered 7.25% senior unsecured notes due 2018.

The 7.25% senior unsecured notes mature on April 15, 2018 with interest payable semi-annually starting on October 15, 2010. The 7.25% senior unsecured notes were issued at 100% of the aggregate principal amount and are effectively subordinate to the Company’s existing and future senior secured debt (to the extent of the value of the assets securing such debt), including debt outstanding under our revolving credit facility. The 7.25% senior unsecured notes may be redeemed, in whole or in part, at any time, at the option of the Company, subject to certain conditions specified in the indenture governing the 7.25% senior unsecured notes. The 7.25% senior unsecured notes are guaranteed, jointly and severally, on a senior unsecured basis by each of our wholly-owned domestic subsidiaries that also guaranteed debt obligations under our prior revolving credit facility or will guarantee debt obligations under our revolving credit facility.

The fair value of the 7.25% senior unsecured notes as of June 30, 2012 was approximately $210.0 million based on quoted market prices.

The Company incurred approximately $4.9 million in issuance costs, which are being amortized to interest expense over the contractual life of the 7.25% senior unsecured notes using the effective interest rate method, resulting in an effective rate of 7.67%.

The indenture governing the 7.25% senior unsecured notes contains customary events of default, as well as restrictive covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and allow to exist certain control provisions. An event of default under the indenture will allow either the trustee of the notes or the holders of at least 25% in principal amount of the then outstanding notes to accelerate, or in certain cases, will automatically cause the acceleration of, the amounts due under the notes. As of June 30, 2012, the Company was in compliance with all required covenants under the indenture.

Stock-Based Compensation

Share-based Compensation [Abstract]

Stock-Based Compensation

Stock-Based Compensation

In May 2011, the Company’s stockholders approved our 2011 Management Incentive Plan (the Plan), which was designed to enable us to attract, retain and motivate key employees. Awards granted under the Plan are settled in shares of Class A common stock. The 2011 restatement of the Plan increased the base number of shares of our Class A common stock reserved for issuance by 1,500,000 shares. 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 31^st of the previous year. On January 3, 2012, 552,466 additional shares were made available for issuance under the Plan. Through June 30, 2012, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 3,392,984. Through June 30, 2012, 4,437,815 shares of our Class A common stock have been issued as a result of the exercise of options granted under the Plan. The Plan expires in May 2021.

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, 2012 and 2011, we recorded $2.0 million and $2.3 million of stock-based compensation cost, respectively. For the six months ended June 30, 2012 and 2011, we recorded $4.4 million and $4.5 million of stock based compensation cost, respectively. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the six months ended June 30, 2012 and 2011, the total recognized tax (deficiency) benefit from the exercise of stock options, vested cancellations and the vesting of restricted stock was $(0.3) million and less than $0.1 million, respectively.

Stock Options-We typically issue options that vest in three equal installments, beginning on the first anniversary of the date of grant. Under the terms of the Plan, the contractual life of the option grants may not exceed eight years. During the six months ended June 30, 2012 and 2011, we issued options that expire five years from the date of grant.

Fair Value Determination-We have used the Black-Scholes-Merton option pricing model to determine 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.

The following weighted-average assumptions were used for option grants during the six months ended June 30, 2012 and 2011:

Volatility-The expected volatility of the options granted was estimated based upon historical volatility of the Company’s share price through weekly observations of the Company’s trading history.

Expected Term-The expected term of options granted to employees during the six months ended June 30, 2012 and 2011 was determined from historical exercises of the grantee population. For all grants valued during the six months ended June 30, 2012 and 2011, the options had graded vesting over three years (33.3% of the options vest annually) and a contractual term of five years.

Risk-free Interest Rate-The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.

Dividend Yield-The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  In the second quarter of 2011, we initiated a regular cash dividend program. We have calculated our expected dividend yield based on an expected cash dividend of $0.84 per share per year.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the six months ended June 30, 2012 and 2011:

	Six months ended
	June 30,
	2012		2011
Volatility	30.49	%	36.00	%
Expected life of options (in years)	3.04		2.95
Risk-free interest rate	0.56	%	1.06	%
Dividend yield	2.25	%	—	%

Stock Option Activity-During the six months ended June 30, 2012, we granted stock options to purchase 400,950 shares of Class A common stock at a weighted-average exercise price of $33.73 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the six months ended June 30, 2012 and 2011, as determined under the Black-Scholes-Merton valuation model, was $5.98 and $10.57, respectively. These options vest in three equal installments over three years and have a contractual term of five years. Option grants that vested during the six months ended June 30, 2012 and 2011 had a combined fair value of $5.5 million and $4.8 million, respectively.

The following table includes information with respect to stock option activity and stock options outstanding for the year ended December 31, 2011 and the six months ended June 30, 2012:

Stock options expected to vest	1,328,497	3.8	$	38.84	$	—
Options exercisable and expected to vest	2,907,984

Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2012 was $8.8 million, which is expected to be recognized over a weighted-average period of 1.8 years and will be adjusted for any future changes in estimated forfeitures.

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 shares issued to employees vest over three years in one-third increments on the first, second and third anniversaries of the grant date, contingent upon employment with the Company on the vesting dates. Restricted shares issued to members of our Board of Directors vest in one year. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest.

Restricted Stock Activity-The following table summarizes the restricted stock activity for the year ended December 31, 2011 and the six months ended June 30, 2012:

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

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 the Company’s 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, 2012, we declared and paid two dividends of $0.21 per share on both classes of common stock. For the same period in 2011, we declared and paid a dividend of $0.42 per share 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 has 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.

The weighted average number of common shares outstanding is computed as follows (in thousands):

For the three months ended June 30, 2012 and 2011, options to purchase 3.0 million and 2.1 million 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, 2012 and 2011, options to purchase 2.9 million and 2.0 million 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, 2012 and 2011, shares issued from the exercise of stock option were 37 thousand and 220 thousand, respectively.
