American Defense Systems, Inc. Reports

First Quarter 2008 Financial Results

First quarter revenue increases 52 percent year-over-year

Management reiterates full year 2008 revenue guidance

HICKSVILLE, N.Y. – May 15, 2008 – American Defense Systems, Inc. “ADSI”, a leading provider of advanced transparent as well as opaque armor, architectural hardening and security products for the defense and homeland defense markets, today announced financial results for the first quarter 2008, ended March 31, 2008.

Mr. Anthony J. Piscitelli, Chairman & Chief Executive Officer of American Defense Systems, Inc,, stated, “I am pleased to report ADSI achieved an impressive 52 percent improvement in top line growth year-over-year during the first quarter. Although some revenues which we expected to generate in the first quarter have been pushed into the second quarter due to slower than expected prototype testing and approval by the military for new equipment orders, based on the strength of our organic growth in the quarter and upcoming availability of new products we are reiterating our annual revenue target range. Our forecast reflects the confidence we have in expanding the market penetration of our armor and architectural business lines as we believe these end markets continue to show signs of growth.

“In late March and early April we successfully secured a total of $15 million in financing aimed at funding our organic growth initiatives, expanding our international sales channels and funding potential targeted acquisitions. As we look out on fiscal 2008, we see new product introductions as providing additional long-term growth drivers to ADSI, including the formal launch of our state-of-the-art T2 interactive live-fire training system as well as the availability of our American Anti Ram vehicle barriers. We believe these innovative new offerings will extend our leadership position within our core defense and homeland defense markets,” concluded Mr. Piscitelli.

Revenues for the first quarter of 2008 were $9.4 million, an increase of 52 percent from the $6.2 million reported for the same period in 2007. Contract backlog as of March 31, 2008 totaled $48 million, up 37 percent compared to the March 31, 2007 contract backlog of $35 million.

Gross margin as a percentage of revenue for the first quarter of 2008 was 42.0 percent as compared to 46.3 percent for the first quarter of 2007.

Notable cash expenditures during the quarter included $1.0 million associated with the development of the company’s state-of-the-art T2 interactive live-fire training system, $0.5 million associated with previously announced acquisitions, $0.5 million related to the company’s SEC

registration and pending public exchange listing initiative and a $0.2 million contribution to the Marine Corps-Law Enforcement Foundation (MCLEF).

Net loss in accordance with Generally Accepted Accounting Principles (GAAP) for the first quarter of 2008 was $1.7 million, or $(0.04) per basic and diluted share, compared to a GAAP net income for the first quarter 2007 of $0.6 million, or $0.01 per basic and diluted share.

GAAP net loss during the first quarter of 2008 also includes the impact of $1.6 million in non-cash charges related to the loss on the adjustment of fair value associated with the series A convertible preferred stock and related warrants as well as stock based compensation expense.

Excluding the $1.6 million in non-cash charges related to the loss on the adjustment of fair value associated with the series A convertible preferred stock and related warrants as well as stock based compensation expense, the company reported non-GAAP loss for the first quarter of 2008 of $0.1 million, or $(0.00) per basic and diluted share. Refer to the “Use of Non-GAAP Measures” section and accompanying financial table for a reconciliation of GAAP financial information to non-GAAP.

ADSI ended the first quarter with approximately $9.8 million in cash and cash equivalents. Subsequent to the end of the first quarter 2008, the company completed the second phase of a previously announced capital raise which provided the company with the final $4.0 million of the $15.0 million financing round announced on April 8, 2008.

Financial Guidance

Based on current business conditions and expectations, ADSI reiterates its previously released fiscal year 2008 top line revenue target of between $47.0 million and $54.0 million, as compared to revenue of $36.5 million reported for fiscal year 2007.

Use of Non-GAAP Measures

The non-GAAP financial measures discussed in the text of this press release and accompanying non-GAAP supplemental information represent financial measures used by American Defense Systems’ management to evaluate the operating performance of the company and to conduct its business operations. Non-GAAP financial measures discussed in this press release exclude non-cash charges related to stock-based compensation expense, losses associated with adjustments from cost to fair value for the company’s series A convertible preferred stock and losses associated with adjustments to fair value for the related warrants. Management uses the non-GAAP financial measures for planning purposes, including the preparation of operating budgets and to determine appropriate levels of operating and capital investments. Management also believes that the non-GAAP financial measures provide additional insight for investors in evaluating ADSI’s financial and operational performance. However, these non-GAAP financial measures are not intended to be an alternative to financial measures prepared in accordance with GAAP and should not be considered in isolation from our GAAP results of operations. A detailed reconciliation between the company’s GAAP and non-GAAP financial results is provided in this press release and investors are advised to carefully review and consider this information as well as the GAAP financial results that are disclosed in the company’s SEC filings.
