ADDvantage Technologies Reports Third Quarter Results

For Fiscal 2006

BROKEN ARROW, Oklahoma, August 7, 2006 - ADDvantage Technologies Group, Inc. (AMEX: AEY), today announced financial results for its fiscal 2006 third quarter ended June 30, 2006.

Revenue for the third quarter of fiscal year 2006 increased 9% to $13.2 million from $12.1 million in the third quarter of 2005. During the quarter, gross profit was $4.2 million, or 32% of total revenue, consistent with $4.3 million, or 35% of total revenue, in the third quarter last year. Net income attributable to common stockholders in the third quarter of 2006 was $1.1 million, or $0.11 per diluted share, compared to $1.2 or, $0.12 per diluted share in the year-earlier period.

For the nine months ended June 30, 2006, revenue totaled $40.3 million compared to $34.2 million in the same period last year, an increase of 18%. During the first nine months gross profit increased to $13.4 million, or 33% of total revenue, from $11.8 million, or 35% of total revenue, in the same period of fiscal 2005.

For the nine months ended June 30, 2006, net income attributable to common stockholders was $3.5 million or $0.35 per diluted share compared to net income of $3.4 million or $0.34 per diluted share for the same period of the prior year. Net income for the prior year did not include the effect of a new accounting requirement for the expensing of stock option grants totaling $93,274 as well as incremental costs related to increasing the bad debt reserve, increased professional fees associated with changing our independent accountants and the recruitment of a new chief financial officer, totaling approximately $220,000.

Ken Chymiak, ADDvantage Technologies Group President and CEO, commented, “We are pleased with the sustained growth in revenue during the third quarter. We continue to experience increasing demand for our new product offerings, along with steady sales of our refurbished products. Throughout the quarter we experienced rising demand in our repair services business. This rising repair demand includes results from the expansion of our wholly owned Tulsat subsidiary’s service agreement with Scientific Atlanta to add Prisma I^TM optics to the list of equipment the Company is authorized to repair. This agreement was in combination with the renewal of Tulsat’s third-party service agreement with Scientific Atlanta through 2008.”

David Chymiak, ADDvantage Technologies Group Chairman of the Board, commented, “Recently, we announced the acquisition of the business and certain assets of Broadband Remarketing International (BRI), a premium remarketing company offering material management services, new and refurbished in-stock consignment inventory, and ‘certified destruction services’ to cable operators in the Northeast. It’s anticipated BRI will have cross-selling opportunities with our extensive client base of approximately 2,000 cable television system operators to sell refurbished digital converter boxes and modems which should increase our revenues and profits as we expand on these product offerings.

David Chymiak concluded, “We are pleased by the solid relationship we have maintained with Scientific-Atlanta as a trusted Value Added Reseller following their merger with Cisco Systems, Inc. Our performance during the first nine months of fiscal 2006 has been steady and, based on the current business trends we are seeing, we remain optimistic heading into fiscal 2007. We continue to experience heightened demand from our clients as they expand their services and compete to offer CATV customers ‘Triple Play’ transmission services, including data, voice and video. While the telecoms and cable broadcasters compete, the CATV equipment makers and distributors, such as ourselves, are positioned to service both sides’ needs. Additionally, we will continue to seek strategic acquisitions that provide incremental growth opportunities and strengthen our one-stop-shop solution.”
