Background

The Company was formed in September 1989 as “ADDvantage Media Group, Inc.”. In December 1999, its name was changed to ADDvantage Technologies Group, Inc.

We (through our subsidiaries) distribute and service a comprehensive line of electronics and hardware for the cable television (“CATV”) industry. The products we sell and service are used to acquire, distribute, receive and protect the communications signals carried on fiber-optic, coaxial cable and wireless distribution systems. Our customers provide an array of communications services including television, high-speed data (internet) and telephony, to single family dwellings, apartments, businesses and institutions such as hospitals, prisons, universities, schools and others.

3

Our primary customers are cable operators (called multiple system operators or “MSOs”) or other resellers that sell to these customers. The MSOs are identified by overall size into three tiers, and we sell to all three of these tier groups. Examples of MSOs we sell to in these tier groups are: Tier 1) large national operators such as Comcast Corporation, Time Warner Communications Inc. and Cox Communications; Tier 2) medium-size national and regional operators such as Cable One and SuddenLink; Tier 3) smaller, local systems.

We conduct our operations through a network of regionally based subsidiaries that focus on servicing customers in different geographic markets. Our operating subsidiaries include Tulsat Corporation (“Tulsat”), Tulsat-Atlanta LLC, ADDvantage Technologies Group of Nebraska, Inc. (dba “Tulsat-Nebraska”), ADDvantage Technologies Group of Texas, Inc. (dba “Tulsat Texas”), ADDvantage Technologies Group of Missouri, Inc. (dba “ComTech Services”), NCS Industries, Inc. (“NCS”), and Adams Global Communications, LLC (“AGC”).

Several of our subsidiaries, through their long relationships with the original equipment manufacturers (“OEMs”) and specialty repair facilities, have established themselves as value-added resellers (“VARs”). Tulsat, located in Broken Arrow, Oklahoma, is a distributor of Cisco video products. Tulsat is a Cisco Premier Partner allowing it to sell Cisco’s IT related products. Tulsat is also designated as an authorized third party Cisco repair center for select video products. NCS, located in Warminster, Pennsylvania, is one of only three distributors of Arris/Motorola broadband products. AGC, located in Lenexa, Kansas, has a reseller agreement with Arris Solutions to sell cable television equipment in the United States. Our subsidiaries also sell products from other OEMs including Alpha, Blonder-Tongue, RL Drake, Corning-Gilbert, Promax, Quintech, Standard and Triveni Digital.

In addition to offering a broad range of new products, we also sell surplus-new and refurbished equipment that we purchase in the market as a result of cable operator system upgrades or an overstock in their warehouses. We maintain one of the industry's largest inventories of new and refurbished equipment, which allows us to expedite delivery of products to our customers. We continue to upgrade our new product offerings to stay in the forefront of the communications broadband technology revolution.

Most of our subsidiaries operate technical service centers that service/repair most brands of CATV equipment.

Overview of the Industry

We participate in markets for equipment sold primarily to MSOs and other communication companies. As internet usage by households continues to increase, more customers are electing to switch from dial-up access services to high-speed services, particularly those offered by MSOs in the United States. Most MSOs offer a “triple-play” bundle of services that includes voice, video and high-speed data over a single network with the objective of capturing higher average revenues per subscriber. To offer these expanded services, MSOs have invested significantly over the past several years to convert their systems to digital networks and to upgrade their cable plants to increase the speed of their communication signals. As a result, many MSOs have well-equipped networks capable of delivering symmetrical high-bandwidth video, two-way high speed data service and telephony to most of their subscribers through their existing hybrid fiber coaxial infrastructure.

The cable television industry has seen and is continuing to see several changes in recent years. The industry for the most part transitioned from analog to digital in 2009 and 2010 and upgraded its headend equipment in connection with this transition. The transition from analog to digital has significantly expanded the capacity of the cable infrastructure as a digital system can transmit two high definition channels or six to ten standard definition channels in the same capacity as it previously required for one channel on an analog system. In addition, the transition to a digital system also allowed for the reduction and consolidation of headends (the place where cable signals originate from the broadcasters). Therefore, since the transition to digital, the cable television industry has not made significant plant expansions or additional bandwidth upgrades, and we do not believe this trend will change until internet television (“IPTV”) technology is fully ready to be deployed. The number of cable operators is also transitioning in that many of the larger MSOs have purchased the smaller operating systems in the United States. These same MSOs have also reduced the number of headends required for their overall systems.

We continue to provide many of the products and services sought by MSOs as they establish and expand their services and territories. Our Company resells current production CATV equipment in competition with other resellers in the market and the Original Equipment Manufacturers ("OEMs") that manufacture them. We also stock and resell refurbished current production and legacy equipment in competition with other resellers. In addition, we

4

repair all of the CATV equipment that we sell in competition with other repair operations. We believe we have differentiated ourselves from the OEMs, other resellers and repair operations in the marketplace in the following ways: 1) we sell both new and refurbished CATV equipment as well as repair what we sell, while most of our competition does not offer all of these services; 2) we stock both new and refurbished inventory; 3) we can reconfigure new and refurbished equipment to meet the different needs of our customers; and 4) we have experienced sales support staff that have the technical know-how to assist our customers regarding solutions for various products and configurations.

In addition, we continue to expand our relationships with vendors and establish new vendors and product lines for our company. We currently offer products from the leading vendors in the cable television industry, Cisco and Arris, which now includes the Motorola Home business. We are a Premier Partner with Cisco and continue to be a leading broadband access network stocking distributor for Arris products. We are also expanding our efforts to increase our market share of Triveni Digital test equipment. In addition, we have our other existing OEM suppliers, including Alpha, Blonder-Tongue, RL Drake, Corning-Gilbert, Promax, Quintech and Standard and look to add other OEM suppliers to satisfy our existing customers’ needs.

Recent Business Developments

Arris Group, Inc. Acquisition of the Motorola Home Business from Google, Inc.

We have contracts with Motorola Home through our NCS subsidiary and with Arris through our AGC subsidiary. On April 17, 2013, Arris Group, Inc. purchased the Motorola Home business from Google, Inc. (the combined entity is referred to as “Arris”). We are still operating under these existing contracts, but we have been informed by Arris that they plan to combine our two contracts into one master contract under ADDvantage. We do not know what changes, if any, there will be under this master contract as compared to the existing contracts.

Business Strategy

In fiscal year 2012, our Board of Directors enacted a strategy to not only try to grow our Company via organic growth but also via acquisitions. We believe we can increase our business organically along three major fronts: 1) expand product offerings among existing OEM vendors, 2) add additional vendors to our product offering mix and 3) expand our sales force. In September 2013, we hired three industry veterans to the Company’s new sales management team to help increase our market share among existing and new customers. The new salespeople are former Motorola employees with over 10 years in the Broadband Access Network division selling cable equipment and over 20 years of sales experience in the CATV industry.

We believe that the current state of the industry may provide opportunities for expansion of our business through acquisitions. While our past acquisitions have primarily added new suppliers to our core resale business or expanded our existing customer base within our current business, we are seeking acquisition opportunities that will enable us to expand the scope of our business within the broader telecommunications industry. In fiscal year 2013, we engaged an investment banking firm to help us identify and ultimately close a strategic acquisition. We are still evaluating several companies in the telecommunications market, and are optimistic that we will identify and execute a strategic acquisition. It should be noted, however, that the identification and completion of acquisitions on terms favorable to the Company and the successful integration of acquired businesses into our existing business are matters posing some risk to any company and about which we can give no assurance.

Products and Services

We offer our customers a wide range of new, surplus-new and refurbished products across the leading OEM suppliers in the industry that are used in connection with video, telephone and internet data signals.

Headend Products – Headend products are used by a system operator for signal acquisition, processing and manipulation for further transmission. Among the products we offer in this category are satellite receivers (digital and analog), integrated receiver/decoders, demodulators, modulators, antennas and antenna mounts, amplifiers, equalizers and processors. The headend of a television signal distribution system is the “brain” of the system; the central location where the multi-channel signal is initially received, converted and allocated to specific channels for distribution. In some cases, where the signal is transmitted in encrypted form or digitized and compressed, the receiver will also be required to decode the signal.

5

Fiber Products – Fiber products are used to transmit the output of cable system headend to multiple locations using fiber-optic cable. In this category, we currently offer products including optical transmitters, fiber-optic cable, receivers, couplers, splitters and compatible accessories. These products convert radio frequencies to light frequencies and launch them on optical fiber. At each receiver site, an optical receiver is used to convert the signals back to RF VHF frequencies for distribution to subscribers.

Access and Transport Products – Access and transport products are used to permit signals to travel from the headend to their ultimate destination in a home, apartment, hotel room, office or other terminal location along a distribution network of fiber optic or coaxial cable. Among the products we offer in this category are transmitters, receivers, line extenders, broadband amplifiers, directional taps and splitters.

Customer Premise Equipment (CPE) – CPE includes digital converters and modems that are boxes placed inside the home that receive, record and transmit video, data and telephony signals. They are the primary interface equipment between the cable operator and the consumer.

Test Equipment – Test equipment is used in the set-up, signal testing and maintenance of electronic equipment and the overall support of the cable television plant. Test equipment is vital in maintaining the proper function and efficiency of this electronic equipment, which helps to provide high quality video, telephone and high speed data to the end user.

Hardware Equipment – We also inventory and sell to our customers other hardware such as connector and cable products.

Revenues by Geographic Area

Our revenues by geographic areas were as follows:

	2013		2012		2011
United States	$	30,013,085	$	29,520,146	$	33,599,080
Canada, Central America, Mexico, South America and Other		3,344,507		5,696,257		4,480,450
	$	33,357,592	$	35,216,403	$	38,079,530

Revenues attributed to geographic areas are based on the location of the customer. All of our long-lived assets are located within the United States.

Sales and Marketing

In 2013, sales of new products represented 61% of our total revenues and refurbished product sales represented 27%. Repair and other services contributed the remaining 12% of revenues.

We market and sell our products to franchise and private MSOs, telephone companies, system contractors and other resellers. Our sales and marketing are predominantly performed by the internal sales and customer service staff of our subsidiaries. We also have outside sales representatives located in various geographic areas. The majority of our sales activity is generated through personal relationships developed by our sales personnel and executives, referrals from manufacturers we represent, trade shows, advertising in trade journals, telemarketing and direct mail to our customer base in the United States. We have developed contacts with MSOs in the United States, and we are constantly in touch with these operators regarding their plans for upgrading or expansion as well as their needs to either purchase or sell equipment.

We maintain a wide breadth of inventory of new and used cable television products and many times can offer our customers same day shipments. Even though we have been decreasing the amount of inventory we carry, we still carry one of the most diverse inventories of any cable television product reseller in the country, and we have access to inventory via our various supply channels. We believe our investment in on-hand inventory, our product supply 

6

channels, our network of regional repair centers and our experienced sales and customer service team create a competitive advantage for us.

We continue to add products and services to maintain and expand our current customer base in North America, Central and South America and other international markets. We believe there is growth potential for sales of new and legacy products in the international market as some operators choose to upgrade to new larger bandwidth platforms, while other customers, specifically in developing markets, desire less expensive new and refurbished legacy products. Even though the terms of our Cisco agreement restrict our activities with respect to reselling Cisco products in international markets, we still can sell our other brands we carry and our refurbished equipment as well. We extend credit on a limited basis to international customers that purchase products on a regular basis and make timely payments. However, for most international sales we require prepayment of sales or letters of credit confirmed by United States banks prior to shipment of products.

Suppliers

In 2013, we purchased approximately 18% of our total inventory purchases either directly from Cisco or indirectly through Cisco's primary stocking distributor and approximately 29% of our total inventory purchases directly from Motorola. In addition to purchasing inventory from OEMs, we also purchase used or surplus-new inventory from MSOs who have upgraded or are in the process of upgrading their systems.

Seasonality

Many of the products that we sell are installed outdoors and can be damaged by storms and power surges. Consequently, we experience increased demand on certain product offerings during the months between late spring and early fall when severe weather tends to be more prominent than at other times during the year.

Competition and Working Capital Practices

The CATV industry is highly competitive with numerous companies competing in various segments of the market. There are a number of competitors throughout the United States buying and selling new and refurbished CATV equipment similar to the products that we offer. However, most of these competitors do not maintain the breadth of inventory that we carry due to working capital limitations. We maintain the practice of carrying the wide breadth of inventory to meet both the customers' urgent needs and mitigate the extended lead times of our suppliers. In addition, even though we do not stock current production Cisco cable television equipment, we can still purchase directly from Cisco’s stocking distributor. We also have a wide array of other equipment suppliers in the event we do not have the necessary inventory in stock. In terms of sales and inventory on hand or available via our supply channels, we believe we are one of the largest resellers in this industry, providing both sales and service of new and refurbished CATV equipment.

We also compete with our OEM suppliers as they can sell directly to our customers. Our OEM suppliers have a competitive advantage over us as they can sell products at lower prices than we offer. As a result, we are often considered a secondary supplier by large MSOs and telephone companies when they are making large equipment purchases or upgrades. However, for smaller orders or items that are needed to be delivered quickly, we often hold an advantage over our OEM suppliers as we carry most inventory in stock and can have it delivered in a shorter time frame than the OEM.

Working capital practices in the industry center on inventory and accounts receivable. We choose to carry a relatively large inventory due to our on hand-on demand business model for both new and used inventory. We have typically utilized excess cash flows to reinvest in new inventory to expand our product offerings. The greatest need for working capital occurs when we make bulk purchases of surplus-new and used inventory, or when our OEM suppliers offer additional discounts on large purchases. However, over the last two years, due to the continued economic downturn, we have continued to reduce our overall inventory levels, which helped in generating additional cash flows of $0.9 million and $2.5 million in 2013 and 2012, respectively. Our working capital requirements are generally met by cash flow from operations and a bank line of credit, which currently permits borrowings up to $7.0 million. We expect to have sufficient funds available from our cash on hand, future excess cash flows and the bank line of credit to meet our working capital needs for the foreseeable future.

Significant Customers

We are not dependent on one or a few customers to support our business. Our customer base consists of approximately 1,050 active accounts. Sales to our largest customer accounted for approximately 4% of our revenues in fiscal year 2013. Approximately 18% of our revenues for fiscal years 2013 and 2012 were derived from sales of products and services to our five largest customers. There are approximately 1,200 cable television operating companies operating approximately 5,000 cable television headends within the United States alone, each of which is a potential customer.

Personnel

At September 30, 2013, we had 122 employees, all full-time. Management considers its relationships with its employees to be excellent. Our employees are not unionized, and we are not subject to any collective bargaining agreements.

We also distribute products from other OEMs including Alpha, Blonder-Tongue, RL Drake, Corning-Gilbert, Promax, Quintech, Standard and Triveni Digital. We also specialize in the sale of surplus-new and refurbished previously-owned CATV equipment to CATV operators and other broadband communication companies. It is through our development of these vendor relationships that we have focused much of our efforts to market our products and services to the cable MSOs and telecommunication companies. These customers provide an array of different communications services as well as compete in their ability to offer subscribers “triple play” transmission services which comprises data, voice and video.

We also operate technical service centers specializing in Cisco video-related products, Motorola, Magnavox and power supply repairs.

Recent Business Developments

Arris Group, Inc. Acquisition of the Motorola Home Business from Google, Inc.

We have contracts with Motorola Home through our NCS subsidiary and with Arris through our AGC subsidiary. On April 17, 2013, Arris Group, Inc. purchased the Motorola Home business from Google, Inc. (the combined entity is referred to as “Arris”). We are still operating under these existing contracts, but we have been informed by Arris that they plan to combine our two contracts into one master contract under ADDvantage. We do not know what changes, if any, there will be under this master contract as compared to the existing contracts.

Business Strategy

In fiscal year 2012, our Board of Directors enacted a strategy to not only try to grow our Company via organic growth but also via acquisitions. We believe we can increase our business organically along three major fronts: 1) expand product offerings among existing OEM vendors, 2) add additional vendors to our product offering mix and 3) expand our sales force. In September 2013, we hired three industry veterans to the Company’s new sales management team to help increase our market share among existing and new customers. The new salespeople are former Motorola employees with over 10 years in the Broadband Access Network division selling cable equipment and over 20 years of sales experience in the CATV industry.

We believe that the current state of the industry may provide opportunities for expansion of our business through acquisitions. While our past acquisitions have primarily added new suppliers to our core resale business or expanded our existing customer base within our current business, we are seeking acquisition opportunities that will enable us to expand the scope of our business within the broader telecommunications industry. In fiscal year 2013, we engaged an investment banking firm to help us identify and ultimately close a strategic acquisition. We are still evaluating several companies in the telecommunications market, and are optimistic that we will identify and execute a strategic acquisition. It should be noted, however, that the identification and completion of acquisitions on terms favorable to the Company and the successful integration of acquired businesses into our existing business are matters posing some risk to any company and about which we can give no assurance.

Results of Operations

Year Ended September 30, 2013, compared to Year Ended September 30, 2012 (all references are to fiscal years)

Total Net Sales. Total net sales decreased $1.8 million, or 5%, to $33.4 million for 2013 from $35.2 million for 2012. The decrease in equipment sales was primarily due to the continued decrease in plant expansions and bandwidth upgrades in the cable television industry, partially offset by increased equipment sales as a result of Hurricane Sandy. New equipment sales decreased $0.8 million, or 4%, to $20.3 million for 2013 from $21.1 million for 2012. Net refurbished sales decreased $0.8 million, or 8%, to $9.0 million for 2013 from $9.8 million for the same period last year. Net repair service revenues decreased $0.3 million, or 8%, to $4.0 million for 2013 from $4.3 million for the same period last year.

Cost of Sales. Cost of sales includes (i) the costs of new and refurbished equipment, on a weighted average cost basis, sold during the period, (ii) the equipment costs used in repairs, (iii) the related transportation costs, and (iv) the labor and overhead directly related to these sales. Cost of sales decreased $1.1 million, or 4%, to $23.8 million for 2013 from $24.9 million for 2012. The decrease in cost of sales was primarily due to lower overall net sales. Cost of sales was also impacted by an increase in the provision for excess and obsolete inventory of $0.4 million to $1.0 million for 2013 from $0.6 million for 2012. Cost of sales as a percent of revenue was 71% for both 2013 and 2012.

Gross Profit. Gross profit decreased $0.8 million, or 8%, to $9.6 million for 2013 from $10.4 million for 2012. Gross profit margins were 29% for 2013 and 2012.

Operating, Selling, General and Administrative Expenses. Operating, selling, general and administrative expenses include all personnel costs, which include fringe benefits, insurance and business taxes, as well as occupancy, communication and professional services, among other less significant cost categories. Operating, selling, general and administrative expenses decreased $0.4 million, or 4%, to $6.8 million for 2013 compared to $7.2 million for 2012. The decrease was due primarily to decreased personnel costs of $0.4 million.

11

Income from Operations. Income from operations decreased $0.4 million, or 13%, to $2.7 million for 2013 from $3.1 million for 2012 for the reasons described above.

Interest Expense. Interest expense decreased $1.1 million to $26,000 for 2013 from $1.1 million for the same period last year. The decrease was due primarily to lower interest expense as a result of the March 2012 payoff of the outstanding amount of $9.4 million under the second term loan under the Amended and Restated Revolving Credit and Term Loan Agreement and a $0.8 million payment made in order to terminate the associated interest rate swap agreement. The interest rate swap agreement termination payment was recorded as interest expense in 2012.

Income Taxes. The provision for income taxes increased by $0.2 million to $1.0 million, or an effective rate of 38.3%, for 2013 from $0.8 million, or an effective rate of 38.0%, for the same period last year.

Year Ended September 30, 2012, compared to Year Ended September 30, 2011

Total Net Sales. Total net sales decreased $2.9 million, or 8%, to $35.2 million for 2012 from $38.1 million for 2011. New equipment sales decreased $4.8 million, or 19%, to $21.1 million for 2012 from $25.9 million for 2011. The decrease in new equipment sales was primarily due to the continued decrease in plant expansions and bandwidth upgrades in the cable television industry, partially offset by $2.0 million of revenue from Adams Global Communications, which was acquired in May 2011. Net refurbished sales increased $2.4 million, or 32%, to $9.8 million for 2012 from $7.4 million for the same period last year. The increase in refurbished equipment sales was primarily due to revenues from Adams Global Communications. Net repair service revenues decreased $0.5 million, or 10%, to $4.3 million for 2012 from $4.8 million for the same period last year.

Cost of Sales. Cost of sales includes (i) the costs of new and refurbished equipment, on a weighted average cost basis, sold during the period, (ii) the equipment costs used in repairs, (iii) the related transportation costs, and (iv) the labor and overhead directly related to these sales. Cost of sales decreased $1.7 million, or 6%, to $24.9 million for 2012 from $26.5 million for 2011. The decrease in cost of sales was primarily due to lower overall net sales. Cost of sales was also impacted by an increase in the provision for excess and obsolete inventory of $0.2 million to $0.6 million for 2012 from $0.4 million for 2011. Cost of sales as a percent of revenue was 71% for 2012 and 70% for the same period last year. The increase in cost of sales as percent of revenue was due primarily to increased sales from Adams Global Communications of customer premise equipment, which typically yields a lower margin than most of our other product lines.

Gross Profit. Gross profit decreased $1.2 million, or 10%, to $10.4 million for 2012 from $11.6 million for 2011. The decrease in gross profit was primarily due to the overall decline in net sales and reduced margins resulting from increased sales of customer premise equipment as discussed above. Gross profit margins were 29% for 2012 as compared to 30% for the same period last year.

Operating, Selling, General and Administrative Expenses. Operating, selling, general and administrative expenses include all personnel costs, which include fringe benefits, insurance and business taxes, as well as occupancy, communication and professional services, among other less significant cost categories. Operating, selling, general and administrative expenses increased $0.6 million, or 9%, to $7.2 million for 2012 compared to $6.6 million for 2011. The increase was due primarily to increased personnel costs of $0.5 million resulting primarily from the acquisition of Adams Global Communications.

Income from Operations. Income from operations decreased $1.8 million, or 36%, to $3.1 million for 2012 from $4.9 million for 2011 for the reasons described above.

Interest Expense. Interest expense increased $0.4 million to $1.1 million for 2012 from $0.7 million for the same period last year. The increase was due primarily to the $0.8 million payment made in order to terminate the interest rate swap agreement in March 2012 in connection with paying off the associated term loan, partially offset by lower interest expense of $0.4 million for 2012 as a result of paying off the term loan. The interest rate swap agreement termination payment was recorded as interest expense.

Income Taxes. The provision for income taxes decreased by $0.9 million to $0.8 million, or an effective rate of 38.0%, for 2012 from $1.7 million, or an effective rate of 40.0%, for the same period last year.

Liquidity and Capital Resources

We finance our operations primarily through internally generated funds, and we also have available to us a bank line of credit of $7.0 million. During 2013, we generated $4.0 million of cash flow from operations. The cash flow from operations was also favorably impacted by $0.9 million from a net decrease in inventory due primarily to management’s efforts to continue to reduce overall inventory purchases.

During 2013, we made principal payments totaling $0.2 million on our first term loan under our Amended and Restated Revolving and Term Loan Agreement ("Credit and Term Loan Agreement") with our primary lender. On March 12, 2012, we paid off the outstanding amount owed of $9.4 million under the second term loan in the Credit and Term Loan Agreement. In connection with the loan payoff, the Company also terminated the associated interest rate swap agreement for $0.8 million. Therefore, the remaining debt on our balance sheet is the first term loan with a balance of $1.5 million at September 30, 2013. The first term loan requires monthly payments of $15,334 plus accrued interest through November 2021.

We expect that our cash and cash equivalents of $8.4 million at September 30, 2013 will be sufficient to finance our working capital needs and scheduled debt payments in the near-term. The $7.0 million line of credit can also be used to finance our working capital requirements as necessary. At September 30, 2013, there was not a balance outstanding under the line of credit. The lesser of $7.0 million or the total of 80% of the qualified accounts receivable plus 50% of qualified inventory is available to us under the revolving credit facility ($7.0 million at September 30, 2013). The entire outstanding balance on the revolving credit facility is due on maturity.

We believe that our cash flow from operations, current cash balances and our existing line of credit provide sufficient liquidity and capital resources to meet our working capital and debt payment needs.

Subsequent to September 30, 2013, the Company signed the Third Amendment to the Amended and Restated Revolving Credit and Term Loan Agreement with its primary financial lender dated November 29, 2013. This amendment extended the Line of Credit maturity to November 28, 2014. The Line of Credit remains at $7.0 million, and the interest rate remains at the prevailing 30-day LIBOR rate plus 2.75%.

Critical Accounting Policies and Estimates

Note 1 to the Consolidated Financial Statements in this Form 10-K for fiscal year 2013 includes a summary of the significant accounting policies or methods used in the preparation of our Consolidated Financial Statements. Some of those significant accounting policies or methods require us to make estimates and assumptions that affect the amounts reported by us. We believe the following items require the most significant judgments and often involve complex estimates.

General

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates and judgments on historical experience, current market conditions, and various other factors we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates under different assumptions or conditions. The most significant estimates and assumptions relate to the carrying value of our inventory and, to a lesser extent, the adequacy of our allowance for doubtful accounts.

Inventory Valuation

Our position in the industry requires us to carry large inventory quantities relative to annual sales, but it also allows us to realize high overall gross profit margins on our sales. We market our products primarily to MSOs and other users of cable television equipment who are seeking products for which manufacturers have discontinued production or cannot ship new equipment on a same-day basis. Carrying these large inventory quantities represents our largest risk.

13

Our inventory consists of new and used electronic components for the cable television industry. Inventory is stated at the lower of cost or market, with cost determined using the weighted-average method. At September 30, 2013, we had total inventory of $22.5 million, consisting of $16.5 million in new products and $6.0 million in used or refurbished products against which we have a reserve of $1.8 million for excess and obsolete inventory, leaving us a net inventory of $20.7 million.

We are required to make judgments as to future demand requirements from our customers. We regularly review the value of our inventory in detail with consideration given to rapidly changing technology which can significantly affect future customer demand. For individual inventory items, we may carry inventory quantities that are excessive relative to market potential, or we may not be able to recover our acquisition costs for sales that we do make. In order to address the risks associated with our investment in inventory, we review inventory quantities on hand and reduce the carrying value when the loss of usefulness of an item or other factors, such as obsolete and excess inventories, indicate that cost will not be recovered when an item is sold. During 2013, we increased our reserve for excess and obsolete inventory by approximately $1.0 million and wrote down the carrying value of certain inventory items by approximately $0.3 million to reflect deterioration in the market demand of that inventory. If actual market conditions are less favorable than those projected by management, and our estimates prove to be inaccurate, we could be required to increase our inventory reserve and our gross margins could be materially adversely affected.

Inbound freight charges are included in cost of sales. Purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs and other inventory expenditures are included in operating expenses, since the amounts involved are not considered material.

Accounts Receivable Valuation

Management judgments and estimates are made in connection with establishing the allowance for doubtful accounts. Specifically, we analyze the aging of accounts receivable balances, historical bad debts, customer concentrations, customer credit-worthiness, current economic trends and changes in our customer payment terms. Significant changes in customer concentration or payment terms, deterioration of customer credit-worthiness, or weakening in economic trends could have a significant impact on the collectability of receivables and our operating results. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, an additional provision to the allowance for doubtful accounts may be required. The reserve for bad debts was $0.3 million at September 30, 2013 and September 30, 2012. At September 30, 2013, accounts receivable, net of allowance for doubtful accounts, was $3.0 million.

Goodwill

Goodwill represents the excess of purchase price of acquisitions over the acquisition date fair value of the net assets of businesses acquired. Goodwill and intangible assets with indefinite useful lives are not amortized and are tested at least annually for impairment. We perform our annual analysis during the fourth quarter of each fiscal year and in any other period in which indicators of impairment warrant additional analysis. Goodwill is evaluated for impairment by first comparing our estimate of the fair value of the reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. Our reporting unit for purposes of the goodwill impairment calculation is our consolidated entity.

Management utilizes a discounted cash flow analysis to determine the estimated fair value of our reporting unit. Significant judgments and assumptions including the discount rate and anticipated revenue growth rate, gross margins and operating expenses are inherent in these fair value estimates, which are based on historical operating results. As a result, actual results may differ from the estimates utilized in our discounted cash flow analysis. The use of alternate judgments and/or assumptions could result in the recognition of different levels of impairment charges in the financial statements. If the carrying value of the reporting unit exceeds its fair value, a computation of the implied fair value of goodwill would then be compared to its related carrying value. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of goodwill, an impairment loss would be recognized in the amount of the excess. If an impairment charge is incurred, it would negatively impact our results of operations and financial position.

We did not record a goodwill impairment for our reporting unit in the three year period ended September 30, 2013. Although we do not anticipate a future impairment charge, certain events could occur that might adversely affect the reported value of goodwill. Such events could include, but are not limited to, economic or competitive conditions, a

14

significant change in technology, the economic condition of the customers and industries we serve, a significant decline in the real estate markets we operate in, and a material negative change in the relationships with one or more of our significant customers or equipment suppliers.  If our judgments and assumptions change as a result of the occurrence of any of these events or other events that we do not currently anticipate, our expectations as to future results and our estimate of the implied value of our reporting unit also may change.

We performed our annual impairment test in the fourth quarter to determine whether an impairment existed and to determine the amount of headroom at September 30, 2013.  Headroom is defined as the percentage difference between the carrying value of the goodwill and its fair value. At September 30, 2013, headroom for the reporting unit was 233%.

Off-Balance Sheet Arrangements

None.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

ADDvantage Technologies Group, Inc.

We have audited the accompanying consolidated balance sheets of ADDvantage Technologies Group, Inc. and subsidiaries as of September 30, 2013 and 2012, and the related consolidated statements of income and comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended September 30, 2013. Our audits of the consolidated financial statements also included the financial statement schedules of ADDvantage Technologies Group, Inc., listed in Item 15(a). These financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of ADDvantage Technologies Group, Inc. and subsidiaries as of September 30, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2013, in conformity with U.S. generally accepted accounting principles in the United States of America. Also, in our opinion, the financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

ADDVANTAGE TECHNOLOGIES GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Description of Business and Summary of Significant Accounting Policies

Description of business

ADDvantage Technologies Group, Inc. through its subsidiaries (collectively, the “Company”) sells new, surplus-new, and refurbished cable television equipment throughout North America, Central America, South America and, to a substantially lesser extent, other international regions that utilize the same technology. In addition, the Company is also a repair center for various cable companies.

Summary of Significant Accounting Policies

Principles of consolidation and segment reporting

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its wholly owned subsidiaries: Tulsat Corporation, Tulsat-Atlanta LLC, ADDvantage Technologies Group of Nebraska, Inc. (dba Tulsat-Nebraska), ADDvantage Technologies Group of Texas, Inc. (dba Tulsat-Texas), NCS Industries, Inc., ADDvantage Technologies Group of Missouri, Inc. (dba ComTech Services) and Adams Global Communications, LLC. All significant inter-company balances and transactions have been eliminated in consolidation. In addition, each subsidiary represents a separate operating segment of the Company and is aggregated for segment reporting purposes.

Cash and cash equivalents

Cash and cash equivalents includes demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.

Accounts receivable

Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Trade receivables are written off against the allowance when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. The Company generally does not charge interest on past due accounts.

Inventory valuation

Inventory consists of new and used electronic components for the cable television industry. Inventory is stated at the lower of cost or market with market defined principally as net realizable value. Cost is determined using the weighted-average method. The Company records inventory reserve provisions to reflect inventory at its estimated realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete.

Property and equipment

Property and equipment consists of software, office equipment, warehouse and service equipment and buildings with estimated useful lives generally of 3 years, 5 years, 10 years and 40 years, respectively. Depreciation is provided using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the remainder of the lease agreement. Gains or losses from the ordinary sale or retirement of property and equipment are recorded in other income (expense). Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized. Depreciation and amortization expense was $0.3 million, $0.4 million and $0.4 million for each of the years ended September 30, 2013, 2012 and 2011, respectively.

23

Goodwill

Goodwill represents the excess of cost over fair value of the assets of businesses acquired. Goodwill is evaluated at least annually for impairment by first comparing our estimate of the fair value of the reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, a computation of the implied fair value of goodwill would then be compared to its related carrying value. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of goodwill, an impairment loss would be recognized in the amount of the excess. Judgments and assumptions are inherent in our estimate of future cash flows used to determine the estimate of the reporting unit’s fair value. The use of alternate judgments and/or assumptions could result in the recognition of different levels of impairment charges in the financial statements. At September 30, 2013 and 2012, the fair value of our reporting unit exceeded its carrying value, so goodwill was not impaired.

Income taxes

The Company provides for income taxes in accordance with the liability method of accounting. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax carryforward amounts. Management provides a valuation allowance against deferred tax assets for amounts which are not considered “more likely than not” to be realized.

Revenue recognition and product line reporting

The Company’s principal sources of revenues are from sales of new, refurbished or used equipment and repair services. As a distributor for several cable television equipment manufacturers, the Company offers a broad selection of inventoried and non-inventoried products. The Company’s sales of different products fluctuate from year to year as its customers’ needs change. Because the Company’s product line sales change from year to year, the Company does not report sales by product line for management reporting purposes and does not disclose sales by product line in these consolidated financial statements.

The Company recognizes revenue for product sales when title transfers, the risks and rewards of ownership have been transferred to the customer, the fee is fixed and determinable and the collection of the related receivable is probable, which is generally at the time of shipment. The stated shipping terms are FOB shipping point per the Company's sales agreements with its customers. Accruals are established for expected returns based on historical activity. Revenue for services is recognized when the repair is completed and the product is shipped back to the customer.

Derivatives

Derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of the changes in the fair value of the derivative are recorded in Other Comprehensive Income and are recognized in the income statement when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in other income (expense). The Company's objective of holding derivatives was to minimize the risk of interest rate fluctuation. As of September 30, 2012, the Company no longer holds derivatives.

Freight

Amounts billed to customers for shipping and handling represent revenues earned and are included in net new sales income, net refurbished sales income and net service income in the accompanying consolidated statements of income and comprehensive income. Actual costs for shipping and handling of these sales are included in cost of sales.

24

Advertising costs

Advertising costs are expensed as incurred. Advertising expense was $0.2 million for each of the years ended September 30, 2013, 2012 and 2011, respectively.

Management estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the cable industry could have a significant impact on the value of the Company's inventory and operating results.

Concentrations of credit risk

The Company holds cash with one major financial institution, which at times exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk.

Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables. Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk. The Company controls credit risk through credit approvals, credit limits and monitoring procedures. The Company performs in-depth credit evaluations for all new customers but does not require collateral to support customer receivables. The Company had no customer in 2013, 2012 or 2011 that contributed in excess of 10% of the total net sales. The Company’s sales to foreign (non-U.S. based customers) were approximately $3.3 million, $5.7 million and $4.5 million for the years ended September 30, 2013, 2012 and 2011, respectively. In 2013, the Company purchased approximately 18% of its inventory either directly from Cisco or indirectly through their primary stocking distributor and approximately 29% of its inventory from Motorola. The concentration of suppliers of the Company’s inventory subjects the Company to risk.

Employee stock-based awards

Share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their grant date fair value over the requisite service period. The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of income and comprehensive income.

Earnings per share

Basic earnings per share are based on the sum of the average number of common shares outstanding and issuable restricted and deferred shares. Diluted earnings per share include any dilutive effect of stock options, restricted stock and convertible preferred stock.

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities. The carrying value of the Company’s line of credit and term debt approximates fair value since their interest rates fluctuate periodically based on a floating interest rate.

25

Note 2 – Inventories

Inventories at September 30, 2013 and 2012 are as follows:

	2013			2012
New	$	16,355,035		$	17,283,788
Refurbished		6,125,418			6,382,597
Allowance for excess and obsolete inventory		(1,750,000	)		(1,000,000	)
	$	20,730,453		$	22,666,385

New inventory includes products purchased from the manufacturers plus “surplus-new”, which are unused products purchased from other distributors or multiple system operators. Refurbished inventory includes factory refurbished, Company refurbished and used products. Generally, the Company does not refurbish its used inventory until there is a sale of that product or to keep a certain quantity on hand.

The Company regularly reviews inventory quantities on hand, and an adjustment to cost is recognized when the loss of usefulness of an item or other factors, such as obsolete and excess inventories, indicate that cost will not be recovered when an item is sold. The Company recorded charges to allow for obsolete inventory during the fiscal years ended September 30, 2013, 2012 and 2011, increasing the cost of sales by approximately $1.0 million, $0.6 million and $0.4 million, respectively.

Note 3 – Income Taxes

The provision (benefit) for income taxes for the years ended September 30, 2013, 2012 and 2011 consists of:

	2013			2012		2011
Current	$	1,051,351		$	532,000	$	1,159,000
Deferred		(15,000	)		234,000		533,000
	$	1,036,351		$	766,000	$	1,692,000

The following table summarizes the differences between the U.S. federal statutory rate and the Company’s effective tax rate for financial statement purposes for the years ended September 30, 2013, 2012 and 2011:

	2013			2012			2011
Statutory tax rate		34.0	%		34.0	%		34.0	%
State income taxes, net of U.S. federal tax benefit		5.4	%		3.5	%		4.6	%
Charges without tax benefit		1.2	%		1.4	%		0.7	%
Tax credits and other exclusions		(2.3	%)		(0.9	%)		0.7	%
Company’s effective tax rate		38.3	%		38.0	%		40.0	%

26

The tax effects of temporary differences related to deferred taxes at September 30, 2013 and 2012 consist of the following:

	2013		2012
Deferred tax assets:
Net operating loss carryforwards	$	414,000	$	500,000
Accounts receivable		116,000		115,000
Inventory		842,000		639,000
Other, net		232,000		196,000
		1,604,000		1,450,000
Deferred tax liabilities:
Financial basis in excess of tax basis of certain assets		731,000		592,000
Net deferred tax asset	$	873,000	$	858,000

The above net deferred tax asset is presented in the Company’s consolidated balance sheets at September 30, 2013 and 2012 as follows:

	2013			2012
Deferred tax asset – current	$	1,066,000		$	920,000
Deferred tax asset (liability) – noncurrent		(193,000	)		(62,000	)
	$	873,000		$	858,000

Utilization of the Company’s net operating loss carryforward, totaling approximately $1.1 million at September 30, 2013, to reduce future taxable income is limited to an annual deductable amount of approximately $0.3 million. The net operating loss carryforward expires in varying amounts in 2019 and 2020.

The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial performance. The Company has concluded, based on its historical earnings and projected future earnings, that it will be able to realize the full effect of the deferred tax assets and no valuation allowance is needed.

Based upon a review of its income tax positions, the Company believes that its positions would be sustained upon an examination by the Internal Revenue Service and does not anticipate any adjustments that would result in a material change to its financial position. Therefore, no reserves for uncertain income tax positions have been recorded. Generally, the Company is no longer subject to examinations by the U.S. federal, state or local tax authorities for tax years before 2010.

27

Note 4 – Accrued Expenses

Accrued expenses at September 30, 2013 and 2012 are as follows:

Employee costs	$	766,201	$	823,978
Taxes other than income tax		154,616		176,296
Interest		996		1,153
Other, net		13,043		28,747
	$	934,856	$	1,030,174

Note 5 – Line of Credit and Notes Payable

Notes Payable

The Company has an Amended and Restated Revolving Credit and Term Loan Agreement (“Credit and Term Loan Agreement”). The only outstanding term loan under the Credit and Term Loan Agreement has an outstanding balance of $1.5 million at September 30, 2013 and is due on November 20, 2021, with monthly principal payments of $15,334 plus accrued interest. The interest rate is the prevailing 30-day LIBOR rate plus 1.4% (1.58% at September 30, 2013) and is reset monthly. This term loan is collateralized by inventory, accounts receivable, equipment and fixtures and general intangibles.

The aggregate minimum maturities of notes payable for each of the next five years are as follows:

2014	$	184,008
2015		184,008
2016		184,008
2017		184,008
2018		184,008
Thereafter		582,572
Total	$	1,502,612

Line of Credit

The Company has a $7.0 million Revolving Line of Credit (“Line of Credit”) under the Credit and Term Loan Agreement with its primary financial lender. At September 30, 2013, the Company had no amount outstanding under the Line of Credit. The Line of Credit requires quarterly interest payments based on the prevailing 30-day LIBOR rate plus 2.75% (2.93% at September 30, 2013), and the interest rate is reset monthly. Any future borrowings under the Line of Credit are due on November 29, 2013. Future borrowings under the Line of Credit are limited to the lesser of $7.0 million or the net balance of 80% of qualified accounts receivable plus 50% of qualified inventory. Under these limitations, the Company’s total Line of Credit borrowing base was $7.0 million at September 30, 2013. Among other financial covenants, the Line of Credit agreement provides that the Company must maintain a fixed charge ratio of coverage (EBITDA to total fixed charges) of not less than 1.25 to 1.0, determined quarterly. The Line of Credit is collateralized by inventory, accounts receivable, equipment and fixtures and general intangibles.

Subsequent to September 30, 2013, the Company signed the Third Amendment to the Amended and Restated Revolving Credit and Term Loan Agreement with its primary financial lender dated November 29, 2013. This amendment extended the Line of Credit maturity to November 28, 2014. The Line of Credit remains at $7.0 million, and the interest rate remains at the prevailing 30-day LIBOR rate plus 2.75%.

28

Note 6 – Stock-Based Compensation and Preferred Stock

Plan Information

The 1998 Incentive Stock Plan (the “Plan”) provides for awards of stock options and restricted stock to officers, directors, key employees and consultants. The Plan provides that upon any issuance of additional shares of common stock by the Company, other than pursuant to the Plan, the number of shares covered by the Plan will increase to an amount equal to 10% of the then outstanding shares of common stock. Under the Plan, option prices will be set by the Board of Directors and may be greater than, equal to, or less than fair market value on the grant date.

At September 30, 2013, 1,024,656 shares of common stock were reserved for the exercise of, or lapse of restrictions on, stock awards under the Plan. Of these reserved shares, 280,141 shares were available for future grants.

Stock Options

Share-based payments to employees, including grants of employee stock options, are recognized in financial statements based on their grant date fair value over the requisite service period. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of income and comprehensive income.

Stock options are valued at the date of the award, which does not precede the approval date, and compensation cost is recognized on a straight-line basis over the vesting period. Stock options granted to employees generally become exercisable over a four or five-year period from the date of grant and generally expire ten years after the date of grant. Stock options granted to the Board of Directors generally become exercisable on the date of grant and generally expire ten years after the date of grant.

A summary of the status of the Company's stock options at September 30, 2013 and changes during the year then ended is presented below:

	Options			Weighted Average Exercise Price		Aggregate Intrinsic Value
Outstanding at September 30, 2012		370,000		$	2.83
Granted		30,000		$	2.33
Exercised		(2,000	)	$	1.65	$	940
Expired		–		$	–
Forfeited		(35,000	)	$	2.43
Outstanding at September 30, 2013		363,000		$	2.83	$	0
Exercisable at September 30, 2013		163,000		$	3.30	$	0

The total intrinsic value of options exercised was $940, $2,640 and $5,670 for the years ended September 30, 2013, 2012 and 2011, respectively.

29

Information about the Company’s outstanding and exercisable stock options at September 30, 2013 is as follows:

		Exercisable	Remaining
	Stock Options	Stock Options	Contractual
Exercise Price	Outstanding	Outstanding	Life
$2.450	250,000	50,000	8.5 years
$3.001	65,000	65,000	4.9 years
$3.450	15,000	15,000	3.4 years
$5.780	15,000	15,000	2.4 years
$4.620	15,000	15,000	1.4 years
$4.400	3,000	3,000	0.4 years
	363,000	163,000

The Company granted nonqualified stock options totaling 30,000 shares and 250,000 shares for fiscal years ended September 30, 2013 and 2012, respectively. No nonqualified stock options were granted in fiscal year 2011. The Company estimated the fair value of the options granted using the Black-Scholes option valuation model and the assumptions shown in the table below. The Company estimated the expected term of options granted based on the historical grants and exercises of the Company's options. The Company estimated the volatility of its common stock at the date of the grant based on both the historical volatility as well as the implied volatility on its common stock. The Company based the risk-free rate that was used in the Black-Scholes option valuation model on the implied yield in effect at the time of the option grant on U.S. Treasury zero-coupon issues with equivalent expected terms. The Company has never paid cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company used an expected dividend yield of zero in the Black-Scholes option valuation model. The Company amortizes the resulting fair value of the options ratably over the vesting period of the awards. The Company used historical data to estimate the pre-vesting options forfeitures and records share-based expense only for those awards that are expected to vest.

The estimated fair value at date of grant for stock options utilizing the Black-Scholes option valuation model and the assumptions that were used in the Black-Scholes option valuation model for the fiscal years 2013 and 2012 stock option grants are as follows:

	2013			2012
Estimated fair value of options at grant date	$	29,040		$	267,925
Black-Scholes model assumptions:
Average expected life (years)		6			6
Average expected volatility factor		41	%		41	%
Average risk-free interest rate		2.95	%		2.99	%
Average expected dividends yield		–			–

Compensation expense related to stock options recorded for the years ended September 30, 2013, 2012 and 2011 is as follows:

	2013		2012		2011
Fiscal year 2008 grant	$	–	$	3,562	$	10,349
Fiscal year 2012 grant		95,560		61,176		–
Fiscal year 2013 grant		1,481		–		–
Total compensation expense	$	97,041	$	64,738	$	10,349

The Company records compensation expense over the vesting term of the related options. At September 30, 2013, compensation costs related to these unvested stock options not yet recognized in the statements of income and comprehensive income was $111,189.

30

Restricted stock

The Company granted restricted stock in March 2013 and 2012 to its Board of Directors totaling 31,815 shares and 31,969 shares, respectively, and in March and May 2011 to its Board of Directors and certain employees totaling 58,920 shares. The restricted stock grants were valued at market value on the date of grant. The restricted shares are delivered to the directors and employees at the end of the 12 month holding period. The fair value of the shares upon issuance totaled $70,000, $70,000 and $170,000 for the 2013, 2012 and 2011 fiscal year grants, respectively. The grants are amortized over the 12 month holding period as compensation expense. Compensation expense related to restricted stock recorded for the years ended September 30, 2013, 2012 and 2011 is as follows:

	2013		2012		2011
Fiscal year 2010 grant	$	–	$	–	$	25,000

Note 7 – Retirement Plan

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures.

We maintain disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)) that are designed to ensure that information required to be disclosed by us in the reports that we file or submit to the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified by the Commission’s rules and forms, and that information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our Chief Executive Officer and Chief Financial Officer evaluated our disclosure controls and procedures as of September 30, 2013. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

Management’s Annual Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) and for the assessment of the effectiveness of internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of financial statements in accordance with accounting principles generally accepted in the United States. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorization of our management and board of directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of September 30, 2013. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (1992). Based on our assessment, we believe that, as of September 30, 2013, our internal control over financial reporting is effective based on those criteria.

This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit us to provide only management’s report in this annual report.

Changes in Internal Control over Financial Reporting.

During the fourth quarter ended September 30, 2013, there has been no change in our internal controls over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Exhibit “A”

PROMISSORY NOTE

(Line #15157)

$7,000,000 Effective November 29, 2013

 Tulsa, Oklahoma

FOR VALUE RECEIVED, the undersigned, ADDVANTAGE TECHNOLOGIES GROUP, INC., an Oklahoma corporation ("Maker"), promises to pay to the order of BOKF, NA dba Bank of Oklahoma ("Lender"), at its offices in Tulsa, Oklahoma, the principal sum of SEVEN MILLION AND NO/100 DOLLARS ($7,000,000.00) or so much thereof as may have been advanced from time to time pursuant to the Loan Agreement (defined below), together with interest thereon from the date of disbursement at a rate equal to the Interest Rate (defined below), payable as follows:

a. Principal. Principal shall be payable at Maturity.

b. Interest. Interest shall be payable quarterly on the last day of each February, May, August, and November, commencing February 28, 2014, and at Maturity.

In addition to terms defined elsewhere in this Note, the following terms shall have the following definitions:

“Base rate” means the Daily Floating LIBOR Rate, plus 2.75% per annum. 

“Business Day” means any day other than a Saturday, Sunday or legal holiday on which commercial banks are authorized or required to be closed in Tulsa, Oklahoma.

"Daily Floating LIBOR Rate" means, for any day, the British Bankers' Association LIBOR rate for a period of one month for deposits in U.S. dollars as reported on the Bloomberg Professional Service Page BBAM 1 as the offered rate for loans in United States dollars for thirty (30) day periods under the caption British Bankers Association LIBOR Rates as of 11:00 a.m. (London time), announced on such day (or if such day is not a Business Day, the immediately preceding Business Day) divided by (ii) the sum of one minus the daily maximum reserve requirement (expressed as a decimal) then imposed under Regulation D of the Board of Governors of the Federal Reserve System (or any successor thereto) for “Eurocurrency Liabilities” (as defined therein). If Bloomberg Professional Service no longer reports the LIBOR or Lender determines in good faith that the rate so reported no longer accurately reflects the rate available to Lender in the London Interbank Market or if such index no longer exists or if Page BBAM 1 no longer exists or accurately reflects the rate available to Lender in the London Interbank Market, Lender may select a replacement index or replacement page, as the case may be.

“Default Rate” means the rate per annum equal to the lesser of: (i) the Base Rate plus six percent (6%) per annum; or (ii) the Maximum Rate.

“Event of Default” means: (i) any failure by Maker to pay any installment of principal or interest when due under this Note; (ii) any failure by Maker to pay any other sums owed to Lender when due under this Note; (iii) any failure by Maker to pay this Note in full on or before the Maturity Date; or (iv) the occurrence of any Event of Default under the Loan Agreement or any other Loan Documents.

“Interest Rate” means the lesser of: (i) the Maximum Rate; or (ii) the Base Rate or the Default Rate, whichever is in effect from time to time hereunder.

“Loan” means the loan from Lender to Maker in the original principal amount of $7,000,000 evidenced by this Note and the Loan Agreement.

“Loan Agreement” means that certain Amended and Restated Revolving Credit and Term Loan Agreement dated November 30, 2010 by and between Maker and Lender evidencing the Loan, together with any amendments or modifications thereto.

“Loan Documents” shall have the meaning set forth in the Loan Agreement and in any event shall include this Note, the Loan Agreement and any other instruments, documents and agreements relating thereto, now existing or hereafter arising.

“Maturity Date” means the earliest to occur of: (i) November 28, 2014; or (ii) the date on which the entire principal amount evidenced by this Note and all accrued and unpaid interest thereon shall be paid or be required to be paid in full, whether by prepayment, acceleration or otherwise in accordance with the terms of this Note, the Loan Agreement or any of the Loan Documents.

“Maximum Rate” means the maximum interest rate allowed by applicable law in effect with respect to the Loan on the date for which a determination of interest accrued hereunder is made and after taking into account all fees, payments and other charges which are, under applicable law, characterized as interest.

“Note” means this $7,000,000 Promissory Note.

If any payment shall be due on a day other than a Business Day, such payment shall be due and payable on the next succeeding Business Day and interest shall accrue to such day. All interest due hereon shall be computed on the actual number of days elapsed (365 or 366) based upon a 360-day year.

All payments under this Note shall be made in lawful currency of the United States of America in immediately available funds at Lender’s office described above without abatement, counterclaim or set-off, and no credit shall be given for any payment received by check, draft or other instrument or item until such time as the holder hereof shall have received credit therefor from the holder’s collecting agent or, in the event no collecting agent is used, from the bank or other financial institution upon which said check, draft or other instrument or item is drawn.

If from any circumstances whatsoever fulfillment of any provision hereof or any of such other agreements shall cause the amount paid to exceed the Maximum Rate, then ipso facto, the amount paid to Lender shall be reduced to the Maximum Rate, and if from any such circumstances Lender shall receive interest which exceeds the Maximum Rate, such amount which would be excessive interest shall be applied to the reduction of the principal of this Note and not to the payment of interest, or if such excessive interest exceeds the unpaid principal balance of this Note, and following application thereof to any other costs, expenses and fees due and owing to Lender under the Loan Agreement or any other Loan Documents, such excess shall be refunded to Maker.

Upon the occurrence of an Event of Default, this Note and all interest accrued hereon shall become due and payable at the election of the holder hereof, without notice or demand. The payment and acceptance of any sum on account of this Note shall not be considered a waiver of such right of election. Upon and after the occurrence of any Event of Default, the outstanding principal balance of this Note shall accrue interest at the Default Rate.

The obligations of Maker hereunder are independent of the obligations to Lender of any present or future guarantor, endorser or other obligor, or any other party who now or hereafter becomes liable under this Note by contract, by operation of law or otherwise (Maker and each such other party are also referred to as an “Obligor”).

Maker waives: (i) diligence, notice of default, non-payment, demand for payment, notice of acceptance of this instrument, the Loan Agreement or any other Loan Documents, and indulgences and notices of any kind; (ii) any delay or failure of Lender in the exercise of any right or remedy; (iii) the release, compromise, subordination, substitution, impairment, or failure to perfect any security or any rights or remedies against any Obligor; (iv) any right to marshaling, subrogation, reimbursement or indemnity, until all indebtedness owed to Lender has been fully and indefeasibly paid and Maker’s ability to obtain credit under the Loan Agreement has been irrevocably terminated; (v) any right to request or obtain from Lender information on any Obligor; and (vi) any act, omission or thing which might operate as a legal or equitable defense or discharge of any Obligor(s). Without limiting any other provisions of this Note, Maker waives presentment, demand for payment, protest, notice of nonpayment, and all suretyship defenses.

Without notice to, or further consent of any Obligor, Maker consents to: (i) every renewal, forbearance, extension of time, and other change in the terms or conditions of any indebtedness; (ii) every waiver of Lender’s rights against any Obligor or any security, without such waiver prohibiting the later exercise of the same or similar rights; and (iii) any election of rights or remedies by Lender, including Lender’s enforcement of this Note without first pursuing Lender’s rights against any Obligor or any security. Any bankruptcy, insolvency, merger, consolidation, dissolution or death of any Obligor shall not affect Maker’s obligations to Lender hereunder. Maker subordinates any claim or security it now or hereafter may have against any other Obligor(s) or its assets to any indebtedness Maker owes to Lender. Without limiting any of Lender’s rights or Maker’s obligations, Maker waives all suretyship defenses. Maker agrees that Lender shall have no duty to advise any Obligor of any information regarding any circumstances bearing upon the risk of nonpayment of any indebtedness owed by Maker to Lender.

Maker and any other Obligor will, on demand, pay all costs, expenses and fees incurred by the holder hereof in connection with the enforcement and collection of this Note, including without limitation reasonable attorneys’ fees, together with any other such costs, expenses and fees required to be paid by Maker under any other Loan Documents. A photographic or other reproduction of this Note shall be admissible in evidence with the same effect as the original Note in any judicial or other proceeding, whether or not the original is in existence.

Notwithstanding any course of dealing or course of performance: (i) neither failure nor delay on the part of Lender to exercise any right, power, or privilege hereunder shall operate, expressly or impliedly, as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power, or privilege; (ii) no notice to or demand upon Maker shall be deemed to be a waiver of the obligation of Maker or the right of Lender to take further action without notice or demand; and (iii) no amendment, modification, rescission, waiver or release of any provision of this Note shall be effective unless the same shall be in writing and signed by the holder hereof.

At any time after the occurrence of an Event of Default, without demand or notice (which Maker expressly waives), and regardless of the adequacy of any other collateral security, Lender may set off against any and all accounts, deposits, credits, collateral and other property now or hereafter in Lender’s possession, custody, safekeeping or control (all of the foregoing whether in Maker’s sole name, jointly with other, or for a specific purpose), and apply same to the amounts outstanding under this Note.

If any provision of this Note or any payments pursuant to this Note shall be held invalid or unenforceable to any extent, the remainder of this Note and any other payments hereunder shall not be affected thereby and shall continue to be valid and enforceable to the fullest extent permitted by applicable law.

To the extent any principal and interest due under any Loan Document is not paid within 10 calendar days of the due date therefor, and, to the extent that the following described fee is deemed to constitute interest, subject to the savings clause set forth in this Note, in addition to any interest or other fees and charges due hereunder or under the applicable Loan Document, Borrower shall pay a late fee equal to 5% of the amount of the payment that was to have been made. Borrower agrees that the charges set forth herein are reasonable compensation to Lender for the acceptance and handling of such late payments. The imposition or collection of this fee shall not, however, constitute a waiver of any default or demand by Lender.

THIS NOTE AND ALL MATTERS RELATING HERETO OR THERETO OR ARISING THEREFROM (WHETHER SOUNDING IN CONTRACT LAW, TORT LAW OR OTHERWISE), SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF OKLAHOMA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. MAKER HEREBY CONSENTS TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE COUNTY OF TULSA, STATE OF OKLAHOMA AND IRREVOCABLY AGREES THAT, SUBJECT TO LENDER’S ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS NOTE SHALL BE LITIGATED IN SUCH COURTS. MAKER EXPRESSLY SUBMITS AND CONSENTS TO THE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS. MAKER HEREBY WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS AND AGREES THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE UPON MAKER BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO MAKER AT THE ADDRESS SET FORTH IN THE LOAN AGREEMENT AND SERVICE SO MADE SHALL BE COMPLETE TEN (10) DAYS AFTER THE SAME HAS BEEN POSTED.

EACH OF MAKER AND LENDER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE OR THE TRANSACTIONS CONTEMPLATED THEREBY AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH OF MAKER AND LENDER ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, WHICH EACH HAS RELIED ON THE WAIVER IN ENTERING INTO THIS NOTE AND THE OTHER LOAN DOCUMENTS, AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH OF MAKER AND LENDER WARRANTS AND REPRESENTS THAT EACH HAS HAD THE OPPORTUNITY OF REVIEWING THIS JURY WAIVER WITH LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS.

This Note is given for an actual loan of money for business purposes and not for personal, family, household, agricultural or residential purposes, and is executed and delivered in the State of Oklahoma and shall be governed by and construed in accordance with the laws of the State of Oklahoma. This Note may not be changed orally, but only by an agreement in writing signed by Maker and Lender.

Unless otherwise provided herein, all notices, demands and requests required or desired to be given hereunder shall be delivered in accordance with the Loan Agreement.

This Note constitutes an extension, renewal and modification, but not a novation or payment, of the $7,000,000 Promissory Note dated November 30, 2012, payable by Maker to the order of Lender.

Deferred		(15,000	)		234,000		533,000
	$	1,036,351		$	766,000	$	1,692,000

The following table summarizes the differences between the U.S. federal statutory rate and the Company’s effective tax rate for financial statement purposes for the years ended September 30, 2013, 2012 and 2011:

	2013			2012			2011
Statutory tax rate		34.0	%		34.0	%		34.0	%

Charges without tax benefit		1.2	%		1.4	%		0.7	%
Tax credits and other exclusions		(2.3%	)		(0.9%	)		0.7	%
Company’s effective tax rate		38.3	%		38.0	%		40.0	%

The tax effects of temporary differences related to deferred taxes at September 30, 2013 and 2012 consist of the following:

	2013		2012
Deferred tax assets:
Net operating loss carryforwards	$	414,000	$	500,000
Accounts receivable		116,000		115,000
Inventory		842,000		639,000
Other, net		232,000		196,000
		1,604,000		1,450,000
Deferred tax liabilities:
Financial basis in excess of tax basis of certain assets		731,000		592,000
Net deferred tax asset	$	873,000	$	858,000

The above net deferred tax asset is presented in the Company’s consolidated balance sheets at September 30, 2013 and 2012 as follows:

	2013			2012
Deferred tax asset – current	$	1,066,000		$	920,000
Deferred tax asset (liability) – noncurrent		(193,000	)		(62,000	)
	$	873,000		$	858,000

Utilization of the Company’s net operating loss carryforward, totaling approximately $1.1 million at September 30, 2013, to reduce future taxable income is limited to an annual deductible amount of approximately $0.3 million.  The net operating loss carryforward expires in varying amounts in 2019 and 2020.

The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial performance. The Company has concluded, based on its historical earnings and projected future earnings, that it will be able to realize the full effect of the deferred tax assets and no valuation allowance is needed.

Based upon a review of its income tax positions, the Company believes that its positions would be sustained upon an examination by the Internal Revenue Service and does not anticipate any adjustments that would result in a material change to its financial position. Therefore, no reserves for uncertain income tax positions have been recorded. Generally, the Company is no longer subject to examinations by the U.S. federal, state or local tax authorities for tax years before 2010.

Business Description and Accounting Policies [Text Block]

Note 1 – Description of Business and Summary of Significant Accounting Policies

Description of business

ADDvantage Technologies Group, Inc. through its subsidiaries (collectively, the “Company”) sells new, surplus-new, and refurbished cable television equipment throughout North America, Central America, South America and, to a substantially lesser extent, other international regions that utilize the same technology. In addition, the Company is also a repair center for various cable companies.

Summary of Significant Accounting Policies

Principles of consolidation and segment reporting

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its wholly owned subsidiaries:  Tulsat Corporation, Tulsat-Atlanta LLC, ADDvantage Technologies Group of Nebraska, Inc. (dba Tulsat-Nebraska), ADDvantage Technologies Group of Texas, Inc. (dba Tulsat-Texas), NCS Industries, Inc., ADDvantage Technologies Group of Missouri, Inc. (dba ComTech Services) and Adams Global Communications, LLC.   All significant inter-company balances and transactions have been eliminated in consolidation.  In addition, each subsidiary represents a separate operating segment of the Company and is aggregated for segment reporting purposes.

Cash and cash equivalents

Cash and cash equivalents includes demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.

Accounts receivable

Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts.  Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions.  Trade receivables are written off against the allowance when deemed uncollectible.  Recoveries of trade receivables previously written off are recorded when received.  The Company generally does not charge interest on past due accounts.

Inventory valuation

Inventory consists of new and used electronic components for the cable television industry.  Inventory is stated at the lower of cost or market with market defined principally as net realizable value.  Cost is determined using the weighted-average method.  The Company records inventory reserve provisions to reflect inventory at its estimated realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete.

Property and equipment

Property and equipment consists of software, office equipment, warehouse and service equipment and buildings with estimated useful lives generally of 3 years, 5 years, 10 years and 40 years, respectively.  Depreciation is provided using the straight-line method over the estimated useful lives of the related assets.  Leasehold improvements are amortized over the remainder of the lease agreement.  Gains or losses from the ordinary sale or retirement of property and equipment are recorded in other income (expense). Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized.  Depreciation and amortization expense was $0.3 million, $0.4 million and $0.4 million for the years ended September 30, 2013, 2012 and 2011, respectively.

Goodwill

Goodwill represents the excess of cost over fair value of the assets of businesses acquired. Goodwill is evaluated at least annually for impairment by first comparing our estimate of the fair value of the reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, a computation of the implied fair value of goodwill would then be compared to its related carrying value. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of goodwill, an impairment loss would be recognized in the amount of the excess. Judgments and assumptions are inherent in our estimate of future cash flows used to determine the estimate of the reporting unit’s fair value. The use of alternate judgments and/or assumptions could result in the recognition of different levels of impairment charges in the financial statements. At September 30, 2013 and 2012, the fair value of our reporting unit exceeded its carrying value, so goodwill was not impaired.

Income taxes

The Company provides for income taxes in accordance with the liability method of accounting.  Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax carryforward amounts.  Management provides a valuation allowance against deferred tax assets for amounts which are not considered “more likely than not” to be realized.

Revenue recognition and product line reporting

The Company’s principal sources of revenues are from sales of new, refurbished or used equipment and repair services.  As a distributor for several cable television equipment manufacturers, the Company offers a broad selection of inventoried and non-inventoried products.  The Company’s sales of different products fluctuate from year to year as its customers’ needs change.  Because the Company’s product line sales change from year to year, the Company does not report sales by product line for management reporting purposes and does not disclose sales by product line in these consolidated financial statements.

The Company recognizes revenue for product sales when title transfers, the risks and rewards of ownership have been transferred to the customer, the fee is fixed and determinable and the collection of the related receivable is probable, which is generally at the time of shipment.  The stated shipping terms are FOB shipping point per the Company's sales agreements with its customers.  Accruals are established for expected returns based on historical activity.  Revenue for services is recognized when the repair is completed and the product is shipped back to the customer.

Derivatives

Derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value.  If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings.  If the derivative is designated as a cash flow hedge, the effective portions of the changes in the fair value of the derivative are recorded in Other Comprehensive Income and are recognized in the income statement when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in other income (expense). The Company's objective of holding derivatives was to minimize the risk of interest rate fluctuation. As of September 30, 2012, the Company no longer holds derivatives.

Freight

Amounts billed to customers for shipping and handling represent revenues earned and are included in net new sales income, net refurbished sales income and net service income in the accompanying consolidated statements of income and comprehensive income. Actual costs for shipping and handling of these sales are included in cost of sales.

Advertising costs

Advertising costs are expensed as incurred.  Advertising expense was $0.2 million for each of the years ended September 30, 2013, 2012 and 2011, respectively.

Management estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.

Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the cable industry could have a significant impact on the value of the Company's inventory and operating results.

Concentrations of credit risk

The Company holds cash with one major financial institution, which at times exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk.

Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables.  Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk.  The Company controls credit risk through credit approvals, credit limits and monitoring procedures.  The Company performs in-depth credit evaluations for all new customers but does not require collateral to support customer receivables.  The Company had no customer in 2013, 2012 or 2011 that contributed in excess of 10% of the total net sales.  The Company’s sales to foreign (non-U.S. based customers) were approximately $3.3 million, $5.7 million and $4.5 million for the years ended September 30, 2013, 2012 and 2011, respectively.  In 2013, the Company purchased approximately 18% of its inventory either directly from Cisco or indirectly through their primary stocking distributor and approximately 29% of its inventory from Motorola.  The concentration of suppliers of the Company’s inventory subjects the Company to risk.

Employee stock-based awards

Share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their grant date fair value over the requisite service period. The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of income and comprehensive income.

Earnings per share

Basic earnings per share are based on the sum of the average number of common shares outstanding and issuable restricted and deferred shares.  Diluted earnings per share include any dilutive effect of stock options, restricted stock and convertible preferred stock.

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities.  The carrying value of the Company’s line of credit and term debt approximates fair value since their interest rates fluctuate periodically based on a floating interest rate.

	$	20,730,453		$	22,666,385

New inventory includes products purchased from the manufacturers plus “surplus-new”, which are unused products purchased from other distributors or multiple system operators.  Refurbished inventory includes factory refurbished, Company refurbished and used products. Generally, the Company does not refurbish its used inventory until there is a sale of that product or to keep a certain quantity on hand.

The Company regularly reviews inventory quantities on hand, and an adjustment to cost is recognized when the loss of usefulness of an item or other factors, such as obsolete and excess inventories, indicate that cost will not be recovered when an item is sold.  The Company recorded charges to allow for obsolete inventory during the fiscal years ended September 30, 2013, 2012 and 2011, increasing the cost of sales by approximately $1.0 million, $0.6 million and $0.4 million, respectively.

Note 6 – Stock-Based Compensation and Preferred Stock

Plan Information

The 1998 Incentive Stock Plan (the “Plan”) provides for awards of stock options and restricted stock to officers, directors, key employees and consultants.  The Plan provides that upon any issuance of additional shares of common stock by the Company, other than pursuant to the Plan, the number of shares covered by the Plan will increase to an amount equal to 10% of the then outstanding shares of common stock.  Under the Plan, option prices will be set by the Board of Directors and may be greater than, equal to, or less than fair market value on the grant date.

At September 30, 2013, 1,024,656 shares of common stock were reserved for the exercise of, or lapse of restrictions on, stock awards under the Plan.  Of these reserved shares, 280,141 shares were available for future grants.

Stock Options

Share-based payments to employees, including grants of employee stock options, are recognized in financial statements based on their grant date fair value over the requisite service period. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of income and comprehensive income.

Stock options are valued at the date of the award, which does not precede the approval date, and compensation cost is recognized on a straight-line basis over the vesting period. Stock options granted to employees generally become exercisable over a four or five-year period from the date of grant and generally expire ten years after the date of grant. Stock options granted to the Board of Directors generally become exercisable on the date of grant and generally expire ten years after the date of grant.

A summary of the status of the Company's stock options at September 30, 2013 and changes during the year then ended is presented below:

	Options			Weighted Average Exercise Price		Aggregate Intrinsic Value
Outstanding at September 30, 2012		370,000		$	2.83
Granted		30,000		$	2.33
Exercised		(2,000	)	$	1.65	$	940

Exercisable at September 30, 2013		163,000		$	3.30	$	0

The total intrinsic value of options exercised was $940, $2,640, and $5,670 for the years ended September 30, 2013, 2012 and 2011, respectively.  

Information about the Company’s outstanding and exercisable stock options at September 30, 2013 is as follows:

The Company granted nonqualified stock options totaling 30,000 shares and 250,000 shares for fiscal years ended September 30, 2013 and 2012, respectively. No nonqualified stock options were granted in fiscal year 2011. The Company estimated the fair value of the options granted using the Black-Scholes option valuation model and the assumptions shown in the table below. The Company estimated the expected term of options granted based on the historical grants and exercises of the Company's options. The Company estimated the volatility of its common stock at the date of the grant based on both the historical volatility as well as the implied volatility on its common stock. The Company based the risk-free rate that was used in the Black-Scholes option valuation model on the implied yield in effect at the time of the option grant on U.S. Treasury zero-coupon issues with equivalent expected terms. The Company has never paid cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company used an expected dividend yield of zero in the Black-Scholes option valuation model. The Company amortizes the resulting fair value of the options ratably over the vesting period of the awards. The Company used historical data to estimate the pre-vesting options forfeitures and records share-based expense only for those awards that are expected to vest.

The estimated fair value at date of grant for stock options utilizing the Black-Scholes option valuation model and the assumptions that were used in the Black-Scholes option valuation model for the fiscal years 2013 and 2012 stock option grants are as follows:

	2013			2012
Estimated fair value of options at grant date	$	29,040		$	267,925
Black-Scholes model assumptions:
Average expected life (years)		6			6
Average expected volatility factor		41	%		41	%
Average risk-free interest rate		2.95	%		2.99	%
Average expected dividends yield	–			–

Compensation expense related to stock options recorded for the years ended September 30, 2013, 2012 and 2011 is as follows:

	2013		2012		2011
Fiscal year 2008 grant	$	–	$	3,562	$	10,349
Fiscal year 2012 grant		95,560		61,176	–
Fiscal year 2013 grant		1,481	–		–
Total compensation expense	$	97,041	$	64,738	$	10,349

The Company records compensation expense over the vesting term of the related options. At September 30, 2013, compensation costs related to these unvested stock options not yet recognized in the statements of income and comprehensive income was $111,189.

Restricted stock

The Company granted restricted stock in March 2013 and 2012 to its Board of Directors totaling 31,815 shares and 31,969 shares, respectively, and in March and May 2011 to its Board of Directors and certain employees totaling 58,920 shares. The restricted stock grants were valued at market value on the date of grant. The restricted shares are delivered to the directors and employees at the end of the 12 month holding period. The fair value of the shares upon issuance totaled $70,000, $70,000 and $170,000 for the 2013, 2012 and 2011 fiscal year grants, respectively. The grants are amortized over the 12 month holding period as compensation expense. Compensation expense related to restricted stock recorded for the years ended September 30, 2013, 2012 and 2011 is as follows:

Accounting Policies, by Policy (Policies)

12 Months Ended

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of consolidation and segment reporting

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its wholly owned subsidiaries:  Tulsat Corporation, Tulsat-Atlanta LLC, ADDvantage Technologies Group of Nebraska, Inc. (dba Tulsat-Nebraska), ADDvantage Technologies Group of Texas, Inc. (dba Tulsat-Texas), NCS Industries, Inc., ADDvantage Technologies Group of Missouri, Inc. (dba ComTech Services) and Adams Global Communications, LLC.   All significant inter-company balances and transactions have been eliminated in consolidation.  In addition, each subsidiary represents a separate operating segment of the Company and is aggregated for segment reporting purposes.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and cash equivalents

Cash and cash equivalents includes demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.

Receivables, Policy [Policy Text Block]

Accounts receivable

Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts.  Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions.  Trade receivables are written off against the allowance when deemed uncollectible.  Recoveries of trade receivables previously written off are recorded when received.  The Company generally does not charge interest on past due accounts.

Inventory, Policy [Policy Text Block]

Inventory valuation

Inventory consists of new and used electronic components for the cable television industry.  Inventory is stated at the lower of cost or market with market defined principally as net realizable value.  Cost is determined using the weighted-average method.  The Company records inventory reserve provisions to reflect inventory at its estimated realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and equipment

Property and equipment consists of software, office equipment, warehouse and service equipment and buildings with estimated useful lives generally of 3 years, 5 years, 10 years and 40 years, respectively.  Depreciation is provided using the straight-line method over the estimated useful lives of the related assets.  Leasehold improvements are amortized over the remainder of the lease agreement.  Gains or losses from the ordinary sale or retirement of property and equipment are recorded in other income (expense). Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized.  Depreciation and amortization expense was $0.3 million, $0.4 million and $0.4 million for the years ended September 30, 2013, 2012 and 2011, respectively.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill

Goodwill represents the excess of cost over fair value of the assets of businesses acquired. Goodwill is evaluated at least annually for impairment by first comparing our estimate of the fair value of the reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, a computation of the implied fair value of goodwill would then be compared to its related carrying value. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of goodwill, an impairment loss would be recognized in the amount of the excess. Judgments and assumptions are inherent in our estimate of future cash flows used to determine the estimate of the reporting unit’s fair value. The use of alternate judgments and/or assumptions could result in the recognition of different levels of impairment charges in the financial statements. At September 30, 2013 and 2012, the fair value of our reporting unit exceeded its carrying value, so goodwill was not impaired.

Income Tax, Policy [Policy Text Block]

Income taxes

The Company provides for income taxes in accordance with the liability method of accounting.  Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax carryforward amounts.  Management provides a valuation allowance against deferred tax assets for amounts which are not considered “more likely than not” to be realized.

Revenue Recognition, Policy [Policy Text Block]

Revenue recognition and product line reporting

The Company’s principal sources of revenues are from sales of new, refurbished or used equipment and repair services.  As a distributor for several cable television equipment manufacturers, the Company offers a broad selection of inventoried and non-inventoried products.  The Company’s sales of different products fluctuate from year to year as its customers’ needs change.  Because the Company’s product line sales change from year to year, the Company does not report sales by product line for management reporting purposes and does not disclose sales by product line in these consolidated financial statements.

The Company recognizes revenue for product sales when title transfers, the risks and rewards of ownership have been transferred to the customer, the fee is fixed and determinable and the collection of the related receivable is probable, which is generally at the time of shipment.  The stated shipping terms are FOB shipping point per the Company's sales agreements with its customers.  Accruals are established for expected returns based on historical activity.  Revenue for services is recognized when the repair is completed and the product is shipped back to the customer.

Derivatives, Policy [Policy Text Block]

Derivatives

Derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value.  If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings.  If the derivative is designated as a cash flow hedge, the effective portions of the changes in the fair value of the derivative are recorded in Other Comprehensive Income and are recognized in the income statement when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in other income (expense). The Company's objective of holding derivatives was to minimize the risk of interest rate fluctuation.

Shipping and Handling Cost, Policy [Policy Text Block]

Freight

Amounts billed to customers for shipping and handling represent revenues earned and are included in net new sales income, net refurbished sales income and net service income in the accompanying consolidated statements of income and comprehensive income. Actual costs for shipping and handling of these sales are included in cost of sales.

Advertising Costs, Policy [Policy Text Block]

Advertising costs

Advertising costs are expensed as incurred.  Advertising expense was $0.2 million for each of the years ended September 30, 2013, 2012 and 2011, respectively.

Use of Estimates, Policy [Policy Text Block]

Management estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.

Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the cable industry could have a significant impact on the value of the Company's inventory and operating results.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of credit risk

The Company holds cash with one major financial institution, which at times exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk.

Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables.  Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk.  The Company controls credit risk through credit approvals, credit limits and monitoring procedures.  The Company performs in-depth credit evaluations for all new customers but does not require collateral to support customer receivables.  The Company had no customer in 2013, 2012 or 2011 that contributed in excess of 10% of the total net sales.  The Company’s sales to foreign (non-U.S. based customers) were approximately $3.3 million, $5.7 million and $4.5 million for the years ended September 30, 2013, 2012 and 2011, respectively.  In 2013, the Company purchased approximately 18% of its inventory either directly from Cisco or indirectly through their primary stocking distributor and approximately 29% of its inventory from Motorola.  The concentration of suppliers of the Company’s inventory subjects the Company to risk.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Employee stock-based awards

Share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their grant date fair value over the requisite service period. The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of income and comprehensive income.

Earnings Per Share, Policy [Policy Text Block]

Earnings per share

Basic earnings per share are based on the sum of the average number of common shares outstanding and issuable restricted and deferred shares.  Diluted earnings per share include any dilutive effect of stock options, restricted stock and convertible preferred stock.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities.  The carrying value of the Company’s line of credit and term debt approximates fair value since their interest rates fluctuate periodically based on a floating interest rate.
