          The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles of the United States of America for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all of the information and disclosures required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring items) considered necessary for fair presentation have been included. Operating results for the period ended December 31, 200630, 2007 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2007.2008. Inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the consolidated financial statements and footnotes thereto included in Argon ST, Inc.’s Annual Report on Form 10-K for the fiscal year ended September 30, 2006.2007. Reclassifications are made to the prior year financial statements when appropriate, to conform to the current year presentation.

          Argon ST, Inc. (“Argon ST” or the “Company”) maintains a September 30 fiscal year-end for annual financial reporting purposes. Argon ST presents its interim periods ending on the Sunday closest to the end of the month for each quarter consistent with labor and billing cycles. As a result, each quarter of each year may contain more or less days than other quarters of the year. Management does not believe that this practice has a material effect on quarterly results or on the comparison of such results.

          Argon ST records contract revenues and costs of operations for interim reporting purposes based on annual targeted indirect rates. At year-end, the revenues and costs are adjusted for actual indirect rates. During the Company’s interim reporting periods, variances may accumulate between the actual indirect rates and the annual targeted rates. Timing-related indirect spending variances are not applied to contract costs, research and development, and general and administrative expenses, but are included in unbilled receivables during these interim reporting periods. These rates are reviewed regularly, and the Company records adjustments for any material, permanent variances in the period they become determinable.

          Argon ST’s accounting policy for recording indirect rate variances is based on management’s belief that variances accumulated during interim reporting periods will be absorbed by management actions to control costs during the remainder of the year. The Company considers the rate variance to be unfavorable when the actual indirect rates are greater than the Company’s annual targeted rates. During interim reporting periods, unfavorable rate variances are recorded as reductions to operating expenses and increases to unbilled receivables. Favorable rate variances are recorded as increases to operating expenses and decreases to unbilled receivables. At December 31, 2006,30, 2007, the unfavorable rate variance totaled $3.5 million$2,877 of which $2.4 million$1,654 was planned for the period. If the Company anticipates that actual contract activities will be different than planned levels, there are alternatives the Company can utilize to absorb the variance: the Company can adjust planned indirect spending during the year, modify its billing rates to its customers, or record adjustments to expense based on estimates of future contract activities. Management expects the variance to be eliminated over the course of the fiscal year and therefore, no portion of the variance is considered permanent.

          If the Company’s rate variance is unfavorable, the modification of the Company’s indirect rates will likely increase revenue and operating expenses. Profit percentages on fixed-price contracts will generally decline as a result of an increase to indirect costs unless compensating savings can be achieved in the direct costs to complete the projects. Profit percentages on cost reimbursement contracts will generally decline as a percentage of total costs as a result of an increase in indirect costs even if the cost increase is funded by the customer. If the Company’s rate variance is favorable, the modification of the Company’s indirect rates will decrease revenue and operating expenses. In this event, profit percentages on fixed-price contracts will generally increase. Profit percentages on cost-reimbursable contracts will generally be unaffected as a result of any reduction to indirect costs, due to the fact that programs will typically expend all of the funds available. Any impact on operating income, however, will depend on a number of other factors, including mix of contract types, contract terms and anticipated performance on specific contracts.

          Basic earnings per share is computed using the weighted average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during each period. The following summary is presented for the fiscal quarters ended December 30, 2007 and December 31, 2006:

          Stock options that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS, because to do so would have been antidilutive, were 1,047,445 and 474,450 for the fiscal quarters ended December 30, 2007 and December 31, 2006, and January 1, 2006 (in thousands, except per share amounts):respectively.

          The Company awarded 7,000 incentive stock options to employees during the fiscal quarter ended December 30, 2007. The incentive stock options vest ratably over 5 years and January 1, 2006, respectively. This stock-based compensation expense reduced both basic and diluted earningsthe weighted average fair value of the options is $7.03 per share by $0.01 and $0.01 and $0.02 and $0.01, respectively, forbased on the fiscal quarters ended December 31, 2006 and January 1, 2006, respectively.assumptions below using a binomial model.

          The Company awarded a total of 21,00032,000 shares to its sixeight non-employee board members on December 13, 2006.5, 2007. The stock will vest one year after the award date. The closing price of the Company’s stock on the date of award was $21.39 per share. The fair value of the awardthese awards is $21.39$18.00 per share and $22,000$39 of stock-based compensation expense attributable to these awards was recorded in the three months ended December 31, 2006,30, 2007, all of which is classified underincluded in General and Administrative expenses.expenses in the accompanying Condensed Consolidated Statements of Earnings.

          The table below (in thousands):reconciles the change in the carrying amount of goodwill for the fiscal quarter ended December 30, 2007.

          The Company maintains a $40,000,000$40,000 line of credit with Bank of America, N.A. (the “Lender”). The credit facility will terminate no later than February 28, 2008 at which time the facility will be subject to renewal. The Company currently expects to renew such facility with similar terms and conditions for an additional 2 year period. The credit facility also contains a sublimit of $15,000,000$15,000 to cover letters of credit. In addition, borrowings on the line of credit bear interest at LIBOR plus 150 basis points. An unused commitment fee of 0.25% per annum, payable in arrears, is also required.

          All borrowings under the line of credit are collateralized by all tangible assets of the Company. The line of credit agreement includes customary restrictions regarding additional indebtedness, business operations, permitted acquisitions, liens, guarantees, transfers and sales of assets, and maintaining the Company’s primary accounts with the Lender. Borrowing availability under the line of credit is equal to the Company’s earnings before interest expense, taxes depreciation and amortization (EBITDA) for the trailing 12 months, calculated as of the end of each fiscal quarter. For the fiscal quarter ending December 31, 2006,30, 2007, EBITDA, on a trailing 12 month basis, was $36,756,000.$35,068. The agreement requires the Company to comply with a specific EBITDA to Funded Debt ratio, and contains customary events of default, including the failure to make timely payments and the failure to satisfy covenants, which would permit the Lender to accelerate repayment of borrowings under the agreement if not cured within the applicable grace period. As of December 31, 2006,30, 2007, the Company was in compliance with these covenants and the financial ratio.

          At December 31, 2006,30, 2007, there were no borrowings outstanding against the line of credit. Letters of credit outstanding at December 31, 200630, 2007 amounted to $1,040,000,$1,480, and $35,716,000$33,588 was available on the line of credit. In January 2008, the Company borrowed $7.0 million from our line of credit to fund its current operations.

          For the three months ended December 31, 2006,As of September 30, 2007, the Company recordedhad repurchased 674,145 shares of treasury stock at an accumulated cost of $10,527, of which, 547,900 shares were purchased under a discrete income tax benefitplan announced by the Board of $104,000 relatedDirectors on August 31, 2007 authorizing the purchase of up to the federal research and development tax credit whichan additional 2,000,000 shares through August 31, 2008.

          The following discussion provides information which management believes is relevant to an assessment and an understanding of the Company’s operations and financial condition. This discussion should be read in conjunction with the attached unaudited condensed consolidated financial statements and accompanying notes as well as our annual report on Form 10-K for the fiscal year ended September 30, 2006.2007.

          Statements in this filing which are not historical facts are forward-looking statements under the provision of the Private Securities Litigation Reform Act of 1955. Such forward-looking statements include, without limitation, statements with respect to total estimated remaining contract values and the Company’s expectations regarding the U.S. government’s procurement activities. Forward-looking statements are not guarantees of future performance and are based upon numerous assumptions about future conditions that could prove not to be accurate. Forward looking statements are subject to numerous risks and uncertainties, and our actual results could differ materially as a result of such risks and other factors. In addition to those risks specifically mentioned in this report and in the other reports filed by the Company with the Securities and Exchange Commission (including our Form 10-K for the fiscal year ended September 30, 2006)2007), such risks and uncertainties include, but are not limited to: the availability of U.S. and international government funding for our products and services; changes in the U.S. federal government procurement laws, regulations, policies and budgets (including changes to respond to budgetary constraints and cost-cutting initiatives); the number and type of contracts and task orders awarded to us; the exercise by the U.S. government of options to extend our contracts; our ability to retain contracts during any rebidding process; the timing of Congressional funding on our contracts; any government delay in award of or termination of our contracts and programs; difficulties in developing and producing operationally advanced technology systems; the timing and customer acceptance of contract deliverables; our ability to attract and retain qualified personnel, including technical personnel and personnel with required security clearances; charges from any future impairment reviews; the future impact of any acquisitions or divestitures we may make; the competitive environment for defense and intelligence information technology products and services; general economic, business and political conditions domestically and internationally; and other factors affecting our business that are beyond our control. All of the forward-looking statements should be considered in light of these factors. You should not put undue reliance on any forward-looking statements. We undertake no obligation to update these forward-looking statements to reflect new information, future events or otherwise, except as provided by law.

          We are a leading systems engineering and development company providing full-service C4ISRC5ISR (command, control, communications, computers, combat systems, intelligence, surveillance and reconnaissance) systems to a wide range of defense and intelligence customers. These systems and services are provided to a wide range of defense and intelligence customers, including commercial enterprises. Our systems provide communications intelligence, electromagnetic intelligence, electronic warfare and information operations capabilities that enable our defense and intelligence customers to detect, evaluate and respond to potential threats. These systems are deployed on a range of military and strategic platforms including surface ships, submarines, unmanned underwater vehicles (UUV), aircraft, unmanned aerial vehicles (UAV), land mobile vehicles, fixed site installations and re-locatable land sites.

          Our revenues are primarily generated from the design, development, installation and support of complex sensor systems under contracts primarily with the U.S. Government and major domestic prime contractors, as well as with foreign governments, agencies and defense contractors.

          Our government contracts can be divided into three major types: cost reimbursable contracts, fixed-price, and time and material.materials. Cost reimbursable contracts are primarily used for system design and development activities involving considerable risks to the contractor, including risks related to cost estimates on complex systems, performance risks associated with real time signal processing, embedded software, high performance hardware, and requirements that are not fully understood by the customer or us, the development of technology that has never been used, and interfaces with other systems that are in development or are obsolete without adequate documentation. Fees under these contracts are usually fixed at the time of negotiation; however, in some cases the fee is an incentive or award fee based on cost, schedule, and performance or a combination of those factors. Although the U.S. government customer assumes the cost risk on these contracts, the contractor is not allowed to exceed the cost ceiling on the contract without the approval of the customer.

          In general, most of our backlog results in salesrevenue in subsequent fiscal years, as we maintain very minimal inventory and therefore the lead time on ordering and receiving material and increasing staff to execute programs has a lag time of several months from the receipt of order.

          Our funded backlog does not include the full value of our contracts because Congress often appropriates funds for a particular program or contract on a yearly or quarterly basis, even though the contract may call for performance that is expected to take a number of years.

          Many of our fixed-price contracts contain provisions under which our customers are required to make payments when we achieve certain milestones. In many instances, these milestone payments occur before we have incurred the associated costs to which the payments will be applied. For example, under certain of our production contracts, our order of materials constitutes a milestone for which we receive a significant payment, but we do not pay the materials vendors until the materials are received and placed into production. We recognize deferred revenue when we receive milestone payments for which we have not yet incurred the applicable costs. As costs are incurred and revenue recognition criteria are met, we recognize revenue.

          As the time lag between our receipt of a milestone payment and our incurrence of associated costs under the contract can be several months, milestone payments under fixed-price contracts can significantly affect our cash position at any given time. The receipt of milestone payments will temporarily increase our cash on hand and our deferred revenue. As costs are incurred under the contract and contract revenue is recognized, cash and deferred revenue associated with the payment will decrease.

          We expect that fluctuations in deferred revenue will occur based on the particular timing of milestone payments under our fixed-price contracts and our subsequent incurrence of costs under the contracts. Due to these fluctuations, our cash position at the end of any fiscal quarter or year may not be indicative of our cash position at the end of subsequent fiscal quarters or years. During the fiscal quarter ended December 31, 2006, we incurred cost on certain fixed-price contracts resulting in a decrease of approximately $9 million of deferred revenues, as compared to the year ended September 30, 2006.

          Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements. These financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ significantly from those estimates. We believe that the estimates, assumptions, and judgments involved in the accounting practices described below have the greatest potential impact on our financial statements and, therefore, consider these to be critical accounting practices.

          General

          The majority of our contracts, which are with the U.S. government, are accounted for in accordance with the American Institute of Certified Public Accountants Statement of Position 81-1,Accounting for Performance of Construction-Type and Production-Type Contracts.These contracts are transacted using written contractual arrangements, most of which require us to design, develop, manufacture and/or modify complex products and systems, and perform related services according to specifications provided by the customer. We account for fixed-

          Anticipated losses on contracts are also recorded in the period in which they become determinable. Unexpected increases in the cost to develop or manufacture a product, whether due to inaccurate estimates in the bidding process, unanticipated increases in material costs, inefficiencies, or other factors are borne by us on fixed-price contracts, and could have a material adverse effect on results of operations and financial condition. Unexpected cost increases in cost reimbursable contracts may be borne by us for purposes of maintaining customer relationships. If the customer agrees to fund cost increases on cost type contracts, the additional work does not have any profit and therefore dilutes margin.

          Indirect rate variance

          We record contract revenues and costs of operations for interim reporting purposes based on annual targeted indirect rates. At year-end, the revenues and costs are adjusted for actual indirect rates. During our interim reporting periods, variances may accumulate between the actual indirect rates and the annual targeted rates. Timing-related indirect spending variances are not applied to contract costs, research and development, and general and administrative expenses, but are included in unbilled receivables during these interim reporting periods. These rates are reviewed regularly, and we record adjustments for any material, permanent variances in the period they become determinable.

          Our accounting policy for recording indirect rate variances is based on management’s belief that variances accumulated during interim reporting periods will be absorbed by management actions to control costs during the remainder of the year. We consider the rate variance to be unfavorable when the actual indirect rates are greater than our annual targeted rates. During interim reporting periods, unfavorable rate variances are recorded as reductions to operating expenses and increases to unbilled receivables. Favorable rate variances are recorded as increases to operating expenses and decreases to unbilled receivables.

          If we anticipate that actual contract activities will be different than planned levels, there are alternatives we can utilize to absorb the variance: we can adjust planned indirect spending during the year, modify our billing rates to our customers, or record adjustments to expense based on estimates of future contract activities.

          If our rate variance is unfavorable, the modification of our indirect rates will likely increase revenue and operating expenses. Profit percentages on fixed-price contracts will generally decline as a result of an increase to indirect costs unless compensating savings can be achieved in the direct costs to complete the projects. Profit percentages on cost reimbursement contracts will generally decline as a percentage of total costs as a result of an increase in indirect costs even if the cost increase is funded by the customer. If our rate variance is favorable, the modification of our indirect rates will decrease revenue and operating expenses. In this event, profit percentages on fixed-price contracts will generally increase. Profit percentages on cost-reimbursable contracts will generally be unaffected as a result of any reduction to indirect costs, due to the fact that programs will typically expend all of the funds available. Any impact on operating income, however, will depend on a number of other factors, including mix of contract types, contract terms and anticipated performance on specific contracts.

          At December 31, 2006,30, 2007, the unfavorable rate variance totaled $3.5$2.9 million of which $2.4$1.7 million was planned. Management deems this variance to be seasonal and expects this variance will be eliminated over the course of theby fiscal year and therefore, no portion of this variance is considered permanent.year-end.

          Costs in excess of the fair value of tangible and identifiable intangible assets acquired and liabilities assumed in a business combination are recorded as goodwill. In accordance with SFAS No. 142, “GoodwillGoodwill and Other Intangible Assets”Assets, we test for impairment at least annually using a two-step approach. Impairment of goodwill is tested at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using a combination of the income, or discounted cash flows approach and the market approach, which utilizes comparable companies’ data. If the carrying amount of the unit exceeds its fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment loss, if any. We performed the test during the fourth quarter of fiscal year 2007 and found no impairment to the carrying value of goodwill.

          We follow the provisions of SFAS No. 144,Accounting for the Impairment or Disposal of Long-Lived Assets(“SFAS No. 144”) in accounting for long-lived assets such as property and equipment and intangible assets subject to amortization. SFAS No.144 requires that long-lived assets be reviewed for impairment annuallywhenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment loss is recognized if the sum of the long-term undiscounted cash flows is less than the carrying amount of the long-lived asset being evaluated. Impairment losses are treated as permanent reductions in the fourth fiscal quarter.carrying amount of the assets.

          We currently determine goodwill impairmentare required to estimate the collectibility of our accounts receivables. Judgment is required in assessing the realization of such receivables, and the related reserve requirements are based on three reporting units. Each reporting unitthe best facts available to us. Since most of our revenue is a component of the Company’s single homogeneous business segment with discrete financial information. Goodwill allocatedgenerated under U.S. government contracts, our current accounts receivable reserve is not significant to the reporting units was determined as of the acquisition dates. There was no structural change to the reporting units during the fiscal quarter ended December 31, 2006.our overall receivables balance.

          We account for stock-based compensation in accordance with In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004),Share-Based Payment, (“SFAS No. 123(R), Share-Based Payment. Under the123R”) which requires that compensation costs related to share-based payment transactions be recognized in financial statements. SFAS No. 123R requires all companies to measure compensation costs for all share-based payments at fair value, recognition provisionsand eliminates the option of using the intrinsic method of accounting provided for in Accounting Principles Board Opinion No. 25,Accounting for Stock Issued to Employees, (“APB No. 25”) which generally resulted in no compensation expense recorded in the financial statements related to the grant of stock options to employees and directors if certain conditions were met.

          Effective October 1, 2005, the Company adopted SFAS No. 123R using the modified prospective method. Under this statement, share-basedmethod, compensation cost iscosts for all awards granted after the date of adoption and the unvested portion of previously granted awards outstanding at the date of adoption will be measured at the grant date based on theestimated fair value and included in cost of the awardrevenues and is recognized as expensegeneral and administrative expenses over the vesting period. Determiningperiod during which an employee provides service in exchange for the fair value of share-based awards at the grant date requires judgment, including estimating expected volatility, dividend yield, expected term and estimated forfeitures of the options granted.award.

          The following table sets forth certain items, including consolidated revenues, cost of revenues, general and administrative expenses, income tax expense and net income, and the changes in these items for the fiscal quarters ended December 31, 200630, 2007 and January 1,December 31, 2006 (in thousands):

          Interest income, increasednet of interest expense, decreased approximately $0.2 million or 64% for the fiscal quarter ended December 30, 2007, as compared to the fiscal quarter ended December 31, 2006. This decrease was a result of lower average cash balances. Cash and cash equivalents on hand was approximately $7.3 million and $30.5 million at December 30, 2007 and December 31, 2006, respectively.

          The provision for income taxes decreased approximately $0.2 million or 9% for the fiscal quarter ended December 30, 2007, as compared to the fiscal quarter ended December 31, 2006. Our effective income tax rate increased to 37.9% for the fiscal quarter ended December 30, 2007, compared to an effective rate of 35.5 % for the fiscal quarter ended December 31, 2006,2006. During the first quarter of fiscal year 2007, we reduced the effective rate by 1.2% due to the reinstatement of a research and development tax credit retroactively to January 1, 2006. During the first quarter of fiscal year 2008, this research and development tax credit expired effective December 31, 2007. As such, we are not estimating that a full year of this credit will be used in fiscal year 2008 which has increased the effective rate by 0.7% as compared to the fiscal quarter ended January 1, 2006. This increase was a result of higher average cash balances. Interest expense was $0.1 million for the fiscal quarter ended January 1, 2006 due to outstanding borrowings on the line of credit at that time. During the quarter ended December 31, 2006, there were no borrowings under the line.

          As a result of the above, net income decreased approximately $0.4$0.9 million, or 7%17%, for the fiscal quarter ended December 31, 200630, 2007 compared to the fiscal quarter ended January 1,December 31, 2006.

          Cash

          At December 31, 2006,30, 2007, we had cash of $30.5$7.3 million compared to cash of $33.5$23.0 million onat September 30, 2006. This2007. The $15.7 million decrease in cash of $3.0 million was primarily the result of net$10.0 million of cash used in operating activities, $3.3 million of capital expenditures and capital additions.$2.8 million of cash used for stock purchases under our stock repurchase plan.

          At December 31, 2006,30, 2007, there were no borrowings outstanding against the line of credit. Letters of credit outstanding at December 31, 200630, 2007 amounted to $1.0$1.5 million, and $35.7$33.6 million was available on the line of credit. In January 2008, we borrowed $7.0 million from our line of credit to fund our current operations. We expect to borrow and repay amounts from our line of credit as needed based on available cash resources and the timing of our cash payments and receipts.

          Cash Flows

          Net cash used in operating activities was $10.0 million in the fiscal quarter ending December 30, 2007, compared to net cash used in operating activities of $2.3 million in the fiscal quarter ending December 31, 2006, compared to net cash used in2006. Cash provided by operating activities of $11.4 million in fiscal quarter ending January 1, 2006. The lower cash used in operating activities was attributable to improved accounts receivable and payables management compared to the prior year. In addition, we were able to put into production $5.5 million of project costs deferred at the end of fiscal year 2006. However, these improvements were offset by $9.0 million of deferred revenue recognized during the fiscal quarter ended December 31, 2006.30, 2007 was comprised of $6.7 million of net income as adjusted for non-cash reconciling items including depreciation and amortization, changes in deferred income taxes and stock-based compensation. Net income, as adjusted for non-cash reconciling items was reduced by $16.7 million as a result of changes in operating assets and liabilities. This change was driven by a $15.5 million increase in accounts receivable and a $5.5 million decrease in accounts payable, partially offset by a $4.3 million of changes in other operating assets and liabilities.

          Net cash used in investing activities was $3.0 million for the fiscal quarter ended December 30, 2007, compared to net cash used in investing activities of $1.3 million for the fiscal quarter ended December 31, 2006, compared to net2006. The increase in use of cash provided byin investing activities was primarily due to $3.3 million of $0.7capital expenditures.

          Net cash used in financing activities was $2.7 million for the fiscal quarter ended January 1, 2006. The decrease is due primarily to cash of $1.1 million acquired in the October 2006 Radix acquisition. Investment in property equipment and software increased by $0.5 million asDecember 30, 2007 compared to fiscal quarter ended January 1, 2006.

     As of December 31, 2006,30, 2007, our contractual cash obligations were as follows (in thousands):
