Background

The Company (through its subsidiaries) provides turn-key wireless infrastructure services for wireless carriers, tower companies and equipment manufacturers, and distributes and services a comprehensive line of electronics and hardware for the telecommunications industry. The Company was incorporated under the laws of Oklahoma in September 1989 as “ADDvantage Media Group, Inc.”  In December 1999, its name was changed to ADDvantage Technologies Group, Inc. In 2019, the Company moved its headquarters from Broken Arrow, Oklahoma to Carrollton, Texas and acquired Fulton Technologies, Inc. (“Fulton”) on January 4, 2019, which established the Company’s Wireless Infrastructure Services segment. The Company’s Telecommunications segment operates through its subsidiaries, Nave Communications Company (“Nave”) and ADDvantage Triton, LLC (“Triton”).

Our wireless infrastructure subsidiary provides services such as wireless macro site development, distributed antenna systems, small cells and project management expertise with national and regional scalability. Fulton's expertise includes site modifications, tower retrofits, including 5G, civil construction, tower erection, utility installation and testing, site acquisition including leasing, zoning and permitting, design and A&E.

For our telecommunications subsidiaries, we sell new, surplus-new and refurbished equipment that we purchase in the market as a result of telecommunications system upgrades or overstock supplies.  We maintain one of the industry's largest inventories of new and used equipment, which allows us to expedite delivery of system-critical products to our customers. In addition, we offer our customers decommissioning services for surplus and obsolete equipment, which we in turn process through our recycling program. We continually evaluate new product offerings in the broader telecommunications industry as technology evolves and upgrade our product offerings to stay current with our customer’s technology platforms.

Website Access to Reports

Our public website is www.addvantagetechnologies.com.  We make available, free of charge through the “Investor Relations” section of our website, our annual reports to stockholders, annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission (“SEC”).  Any material we file with or furnish to the SEC is also maintained on the SEC website (www.sec.gov).

The information contained on our website, or available by hyperlink from our website, is not incorporated into this Form 10-K or other documents we file with, or furnish to, the SEC.  We intend to use our website as a means of

disclosing material non-public information and for complying with our disclosure obligations under Regulation FD.  Such disclosures will be included on our website in the “Investor Relations” section.  Accordingly, investors should monitor such portions of our website, in addition to following our press releases, SEC filings and public conference calls and webcasts.

Operating Segments

During 2019, the Company changed its organizational structure with the acquisition of Fulton and the sale of the Cable Television (“Cable TV”) segment.  As a result of these changes, information that the Company’s management team regularly reviews for purposes of allocating resources and assessing performance changed.  The Company’s current reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”).  The Cable TV segment was sold on June 30, 2019.  Therefore, the Company has classified the Cable TV segment as discontinued operations (see Note 4 – Discontinued Operations).

Products and Services

Wireless Segment

We provide turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers that support these wireless carriers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.

As part of the Fulton acquisition, we were able to hire and retain the majority of Fulton’s existing employee base.  Fulton now has approximately 100 employees.  Fulton performs equipment installations, upgrades and maintenance services for its customers primarily on communication towers. Having the proper safety record, training capability and quality oversight is paramount in the industry. Fulton has prided itself in performing work in a safe and timely manner and delivering high-quality services to its Clients. Demand for tower equipment installation and upgrade services will soon again be at an all-time high sometime in the 2nd half of calendar 2021. We expect this trend to continue for the foreseeable future as wireless carriers continue to add capacity, expand their networks and upgrade their current technology for high speed connectivity to 5G.

Fulton also supports the installation and support of temporary tower locations.  This niche and growing business includes the erection of temporary towers to allow for the maintenance of permanent locations without causing a degradation of wireless coverage in the area.  In addition, Fulton provides temporary tower solutions for special events that require an increase of coverage and capacity for festivals, concerts and sporting events.  Fulton has an inventory of temporary poles of different sizes and uses a unique installation process for the quick deployment of a tower location with little to no environmental impact. Our Special Event tower business was impacted severely during fiscal year 2020 due to Covid-19 and the government restrictions on large crowds and meetings for safety reasons. Summer festivals, county fairs, large sporting events and the Democratic National Convention in Milwaukee were all canceled.

Telco Segment

The Telco segment provides quality new and used telecommunication networking equipment, including both central office and customer premise equipment, to its customer base of telecommunications providers, enterprise customers and resellers by utilizing its inventory from a broad range of manufacturers as well as other supply channels.  This segment also offers its customers repair and testing services for telecommunications networking equipment.  In addition, this segment offers its customers decommissioning services for surplus and obsolete equipment, which it in turn processes through its recycling program.

Central Office Equipment – Central office equipment includes optical transport, switching, and data center equipment on a customer’s communication network.  Optical equipment products aggregate and transport internet traffic; switching equipment products originate, terminate and route voice traffic; and data equipment products transport internet and voice over internet protocol traffic via routers.

Customer Premise Equipment  – Consumer premise equipment includes integrated access devices, channel banks, internet protocol private branch exchange or IP PBX phones, and routers that are placed inside the customer site that will receive the communication signal from the communication services provider. This piece of our Telco

4

business was severely impacted by the closing of all major office complexes throughout the US in 2020. It has slowly been recovering but at September 30, 2020 was not completely back to normal.

In addition, we offer our customers decommissioning services for surplus and obsolete telecom equipment, which we then process through our Responsible Recycling (“R2”) -certified recycling program.

Revenues by Geographic Areas

Our revenues by geographic areas were as follows for the years ended September 30, 2020 and 2019, in thousands:

	2020		2019
United States
Wireless	$	21,354	$	22,919
Telco	26,880		29,789
Canada, Central America, Asia, Europe, Mexico, South America and Other
Telco	1,948		2,410
	$	50,182	$	55,118

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

Wireless Segment

The Wireless segment accounted for 43% and 41% of consolidated revenues for the years ended September 30, 2020 and 2019, respectively. In 2020, wireless tower and small cell services, including the procurement of the requisite materials, represented substantially all of the Wireless segment’s revenues.  In this segment, we market and sell our products to wireless carriers, wireless equipment providers and tower companies.

Telco Segment

The Telco segment accounted for 57% and 58% of consolidated revenues for the years ended September 30, 2020 and 2019, respectively. Sales of new products represented 29% of revenues and refurbished products represented 66%. Repair services represented less than 1% of Telco sales.  Recycle sales and other services contributed the remaining 4% of Telco segment revenues. In this segment, we market and sell our products to franchise and private MSOs, telecommunication companies, system contractors, other industry resellers, enterprise customers and directly to consumers via on-line sales. Our sales and marketing are predominantly performed by our experienced internal sales and customer service staff, outside sales representatives located in various geographic and strategic areas of the country, and many on-line sales channel platforms such as our own website, Amazon and Newegg.  The majority of our sales activity is generated through customer relationships developed by our sales personnel and executives, referrals from manufacturers we represent, and on-line advertising.

We maintain a wide breadth of new and used products and many times can offer our customers same day shipments.  We believe we carry one of the most diverse inventories of any telecommunication product reseller in the country, and we have access to additional inventory via our various supply channels.  We believe our investment in on-hand inventory, our product supply channels, and our experienced sales and customer service team create a competitive advantage for us.

Suppliers

The Telco segment primarily purchases its used inventory from telecommunication companies and wholesale suppliers that have excess equipment on hand or have upgraded their systems or from other resellers in this industry.

5

Seasonality

In the Wireless segment, the services that we provide on our customers’ wireless towers are outdoors and can be damaged by storms and power surges. Consequently, we can experience increased demand on certain product offerings during the months between late spring and early fall when severe weather or consistent rain tends to be more prominent than at other times during the year. Winter months are generally slower due to the cold weather conditions, and the inability to access wireless towers during periods of heavy snow and ice.

In the Telco segment, we do not anticipate that quarterly operating results will generally be impacted by seasonal fluctuations, other than normal business fluctuations during the winter holiday season.

Competition

Wireless Segment

The wireless infrastructure services business competes with other wireless service companies on a local, regional or national basis. In some areas, Fulton provides services that its customers can also provide utilizing their in-house personnel. However, most of the direct competition in the Wireless segment is regionally based from companies of a similar size. In niche areas of service, like our Special Events COW and Temporary Pole business in the Midwest and in certain markets, the Wireless segment has few competitors due to its expertise and the required investment in equipment and assets. The level of competition can vary based on demand characteristics in certain markets.

For the Wireless segment, we believe our differentiation from other service providers in the marketplace is primarily the following:

•Past performance and experience developed over 30 years;

•Robust safety organization;

•Ability to recruit and retain personnel and a Midwest workforce of long-tenured personnel of 20 to 30-plus years of service;

•Broad range of multi-year master service agreements in place with Carriers, OEM’s, Tower Owners and Integrators;

•Industry relationships; and

•Having a diversified offering of services based on know-how and equipment.

Telco Segment

The overall telecommunications equipment industry is highly competitive.  We compete with numerous resellers in the marketplace that sell both direct and on-line.

For the Telco segment, we believe our differentiation from other resellers includes:

•Broad range of new, refurbished and used inventory, which allows us to meet our customers’ timing needs;

•Ability to source unique and sometimes rare, high demand inventory;

•Offer a range of repair and testing capabilities to help improve the quality of our inventory as well as offering repair and testing of equipment as a service to our customers and vendors;

•Experienced sales support staff that maintain strong and longstanding relationships with our customers;

•Sales force that has a strong technical knowledge of the products we offer;

•Quality certifications:  TL9000 (telecommunications quality certification), ISO 14001 (environmental management certification), OHSAS18000 (occupational safety and health management certification), and R2 (EPA responsible recycling practices for electronics); and

•Provide multiple services for our customers including deinstallation and decommission of products, storage and management of spare inventory and recycling.

Working Capital Practices

Working capital practices in our business differ by segment. In the Wireless segment, we utilize quick payment accounts receivable programs with our major customers and our bank to decrease the amount of time between project completion and payment. The majority of working capital needs result from the payment of project related costs before invoicing the customer. This includes personnel, subcontractors, equipment rentals and materials.  Although the quick payment programs are in place to accelerate receivable payments, working capital is necessary to complete the jobs and provide the necessary closeout packages required for customer approval. In addition, we also have access to our revolving bank line of credit to meet our working capital needs.

6

In the Telco segment, working capital centers on inventory and accounts receivable.  We choose to carry a relatively large volume of inventory due to our on-hand, on-demand business model.  We typically utilize excess cash flows to reinvest in inventory to maintain or 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. Our working capital requirements are generally met by cash flows from operations and our revolving bank line of credit.

The Company has a $4.0 million revolving line of credit agreement with its primary financial lender, which had a maturity date of December 17, 2020. On December 16, 2020, the Company renewed its revolving bank line of credit for one year to a maturity date of December 17, 2021.  As part of this renewal, the revolving bank line of credit remained $4.0 million, or the sum of 80% of eligible accounts receivable and 60% of eligible inventory, as defined by the loan agreement, with quarterly interest payments based on Wall Street Journal Prime Rate ("WSJP"), floating, with the addition of a 4% floor rate and a fixed charge coverage ratio of 1.25x to be tested quarterly beginning June 30, 2021. We expect to have sufficient funds available from our cash on hand, future cash flows, quick payment accounts receivable programs and the bank revolving line of credit to meet our working capital needs for the foreseeable future.

Significant Customers

During the year ended September 30, 2020, though we were not dependent upon a single or few customers to support our consolidated revenues, our Wireless segment realized increased concentration in revenues from our largest customers. A single customer, AT&T Mobility, accounted for 14% of consolidated revenues, and 32% of our Wireless segment revenues. Our top five Wireless customers accounted for 33% of consolidated revenues and 77% of Wireless segment revenues during fiscal year 2020.

During the year ended September 30, 2019, we were not dependent upon a single or few customers to support our consolidated revenues. Sales to our largest customer accounted for approximately 12% of our consolidated revenues in fiscal year 2019. Sales to our largest five customers, four of which were in the Wireless segment and one in the Telco segment, were 37% of our consolidated revenues in 2019.

Impact of Inflation on Operations

Inflation in the United States has been relatively low in recent years and did not have a material impact on our results of operations for the fiscal years ended September 30, 2020 and 2019.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Personnel

At September 30, 2020, we had 124 employees, including 123 full-time employees.  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.

Item 2.    Properties.

Each subsidiary leases property for office, warehouse and service center facilities. Our corporate headquarters is located in Carrollton, Texas. Our Wireless Segment leases additional space in Chicago, Illinois, and our Telco Segment has operations in Miami, Florida and Huntsville, Alabama. We believe that our current facilities are adequate to meet our needs.

The Company has a right-of-use for a buildings in Minneapolis, Minnesota and Jessup, Maryland which were no longer being used in operations. The Minnesota property was subleased and the Maryland property was partially subleased at September 30, 2020.

7

Item 3.    Legal Proceedings.

From time to time in the ordinary course of business, we are a party to various types of legal proceedings.  We do not believe that these proceedings, individually or in the aggregate, will have a material adverse effect on our financial position, results of operations or cash flows.

General

The Company reports its financial performance based on two external reporting segments: Wireless and Telecommunications.  These reportable segments are described below.

Wireless Infrastructure Services (“Wireless”)

On January 4, 2019, the Company purchased substantially all of the net assets of Fulton, which comprises the Wireless segment.  Fulton provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers that support these wireless carriers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.

9

Telecommunications (“Telco”)

The Company’s Telco segment sells new and refurbished telecommunications networking equipment, including both central office and customer premise equipment, to its customer base of telecommunications providers, enterprise customers and resellers located primarily in North America. This segment also offers its customers repair and testing services for telecommunications networking equipment. In addition, this segment offers its customers decommissioning services for surplus and obsolete equipment, which it in turn processes through its recycling program.

Recent Business Developments

COVID-19

On March 11, 2020, the World Health Organization declared the current outbreak of COVID-19 to be a global pandemic, and on March 13, 2020, the United States declared a national emergency. In response to these declarations and the rapid spread of COVID-19, federal, state and local governments have imposed varying degrees of restrictions on business and social activities to contain COVID-19, including quarantine and “stay-at-home” or “shelter-in-place” orders in markets where we operate. Despite these “stay-at-home” or “shelter-in-place” orders, we are classified as an essential business due to the services and products we provide to the telecommunications industry. Therefore, we continue to operate in the markets we serve, but most of our back-office and administrative personnel were working from home through September 30, 2020. Although we can continue to operate our businesses, our revenues have slowed, especially in our Wireless segment, due to the carriers slowing down various wireless tower projects. We have not experienced a material disruption in our supply chain to date; however, we expect COVID-19 could materially negatively affect the supply chain, customer demand for our telecommunications products or further delay wireless carriers’ infrastructure build plans in the coming months as a result of the disruption and uncertainty it is causing. There is considerable uncertainty regarding the extent to which COVID-19 will continue to spread and the extent and duration of governmental and other measures implemented to try to slow the spread of COVID-19, such as large-scale travel bans and restrictions, border closures, quarantines, shelter-in-place orders and business and government shutdowns. Restrictions of this nature have caused, and may continue to cause, us, our subcontractors, suppliers and other business counterparties to experience operational delays.

In response to COVID-19, we have taken a variety of measures to ensure the availability of our critical infrastructure, promote the health and safety of our employees, and support the communities in which we operate. These measures include providing support for our customers as reflected in the FCC's "Keep Americans Connected" pledge, requiring work-from-home arrangements for a large portion of our workforce and imposing travel restrictions for our employees where practicable, canceling physical participation in meetings, events and conferences, and other modifications to our business practices. We will continue to actively monitor the situation and may take further actions as may be required by governmental authorities or that we determine are in the best interests of our employees, customers, business partners and stockholders.

While we continue to assess the COVID-19 situation, the extent to which the COVID-19 pandemic may impact our business, operating results, financial condition, or liquidity in the future will depend on future developments, including the duration of the outbreak, travel restrictions, business and workforce disruptions, and the effectiveness of actions taken to contain and treat the virus.

Wireless Segment Operating Results

During 2020, Fulton achieved revenues of $21.4 million.  As part of the 2019 acquisition, we hired and retained the majority of Fulton’s existing employee base, and we continue to successfully recruit strong industry talent throughout the business to help us implement operational improvements with a focus on improving our quality and project margins.  We are seeing increased opportunities in the industry as wireless carriers prepare for the roll out of 5G and the required densification of their networks.  We believe the recent merger news in the industry will present additional opportunities as networks are rationalized and a new carrier potentially expands their network to gain market share. Our goal is to solidify our processes and project oversight to successfully and profitably take advantage of new growth opportunities as the 5G expansion becomes essential.  We believe the initial stages of integration with ADDvantage have been successful and Fulton will continue to provide strong revenue growth and gradually improving margins.

10

Telco Segment

We continue to see efficiencies from the operational restructuring put in place during 2019, which enabled us to focus our core team on sales, procurement and recycling opportunities. We are also ramping up our repair activities to take advantage of our new capabilities as we further expand our business lines. Our teams across both Nave and Triton have strong experience in online marketing.

At Triton, our facility is designed to streamline our processes, including inventory management, shipping and receiving and the refurbishment operations. We have developed the internal systems necessary to expand our refurbishment capabilities and new equipment sales by adding additional product lines and manufacturers. We have also increased our focus on the brokerage business and internet sales by expanding our sales channels. We believe that Triton is poised to expand, capture additional market share and develop new customers. 

Line of Credit and Notes Payable

Subsequent to September 30, 2020, the Company renewed its revolving bank line of credit for one year to a maturity date of December 17, 2021.  As part of this renewal, the revolving bank line of credit remained $4.0 million, or the sum of 80% of eligible accounts receivable and 60% of eligible inventory, as defined by the loan agreement, with quarterly interest payments based on WSJP, floating, with the addition of a 4% floor rate and a fixed charge coverage ratio of 1.25 to be tested quarterly beginning June 30, 2021.

Results of Operations

Year Ended September 30, 2020, compared to Year Ended September 30, 2019 (all references are to fiscal years)

Consolidated

Consolidated sales decreased $4.9 million, or 9%, to $50.2 million for 2020 from $55.1 million for 2019.  The decrease in sales was related to $1.6 million in the Wireless segment and $3.4 million in the Telco segment, mainly attributable to delays in capital spending by our major wireless customers as they transitioned budgets from 4G to 5G, and the decrease in demand for office telecommunications equipment as consumers shifted to work-from-home.

Operating expenses increased $1.8 million to $8.2 million for the twelve months ended September 30, 2020 compared with $6.4 million for the same period last year. The increase in operating expenses was due primarily to a full year of operating expenses for the Wireless segment in 2020 compared to nine months of expenses included in the previous year, additional facility costs as a result of moving into Triton’s new facility in the first fiscal quarter of 2020 and additional personnel costs.

Consolidated gross profit decreased $1.8 million, or 13%, to $11.7 million for 2020 from $13.5 million for 2019.  Telcom gross profit decreased $2.0 million due to write-downs of Telcom inventory, partially offset by an increase in gross margin in our Wireless segment of $0.2 million.

Consolidated selling, general and administrative ("SG&A") expenses include overhead costs, which primarily consist of personnel costs, insurance, professional services, and communication, among other less significant cost categories. SG&A increased $1.8 million or 28% to $8.2 million in 2020 compared to $6.4 million in 2019. Increased selling and general and administrative expense during 2020 were related to increased amortization of share-based compensation expense of $0.7 million and increased costs for facilities and information technology of $0.5 million as we moved our headquarters to Carrollton, Texas.

The Company recorded impairment charges of $8.7 million on intangibles including goodwill and $0.7 million on its right-of-use asset Telco Segment for the year ended September 30, 2020. See Note 1. Summary of Significant Accounting Policies and Note 10. Leases in the consolidated financial statements for further discussion of impairments.

The income tax benefit from continuing operations was $1.2 million for 2020 and $13,000 for 2019, or an effective tax benefit rate of 6.7% and 0.3% respectively. The benefit in 2020 was as a result of the CARES Act, the Company took advantage of a provision to carry back net operating losses generated in 2018 through 2020 for a period of five years. As a result, the Company’s effective tax rate included an income tax benefit recognized during the year ended September 30, 2020 related to tax losses generated during the fiscal year up to the amount that the Company estimates is realizable based upon taxable income in the carry back periods. Therefore, as of September

11

30, 2020, the Company recorded a $1.2 million of income tax receivable and recorded a current benefit for income taxes. The Company continues to provide a valuation allowance of $6.4 million for net deferred assets where the Company believes it is more likely than not that those deferred taxes will not be realized.

Segment results

Wireless

Revenues for the Wireless segment were $21.4 million and $23.0 million for the years ended September 30, 2020 and 2019, respectively, a decrease of 7%. Our Midwest operation was impacted by the crowd restrictions placed by government agencies for public safety due to Covid-19. We estimate that about $4 million in revenue was lost due to the cancellation of summer festivals, county fairs, air shows, professional sporting events and the DNC convention in Milwaukee which all traditional require us to build large, complex temporary Cell Sites on Wheels ("COWs") that are also highly profitable. We also were impacted by a significant lag in construction activity due to the delayed approval by the Justice Department of the Sprint-T-Mobile merger and other delays in building out 5G infrastructure resulted from the COVID-19 pandemic.

Gross profit increased $0.2 million year over year, and gross margins were 31% and 28% for the years ended September 30, 2020 and 2019, respectively.

Operating, selling, general and administrative expenses were $10.2 million and $7.9 million for the years ended September 30, 2020 and 2019. This increase is mainly attributable to the inclusion of a full year of expense during 2020 compared to approximately nine months of expense during 2019. During 2019, these expenses included $0.2 million of acquisition costs in connection with the acquisition of Fulton as well as integration expenses of $0.3 million.

Telco

Revenues for the Telco segment were $28.8 million and $32.2 million for the years ended September 30, 2020 and 2019, respectively, a decrease of $3.4 million, or 10%. The decrease in sales resulted from decreased spending on office telecommunications equipment as workers sheltered-in-place during the COVID-19 pandemic.

Gross profit decreased $2.0 million, or 28%, to $5.1 million for the year ended September 30, 2020 compared to $7.1 million for the same period last year.  Gross margin was 18% and 22% for the years ended September 30, 2020 and 2019, respectively. Gross margin decreased primarily due to an increase in obsolescence expense and lower of cost or net realizable value expense of $1.8 million.

Operating, selling, general and administrative expenses were $7.3 million and $8.3 million for the years ended September 30, 2020 and 2019 respectively. Included in operating expense for the Telco segment, is $0.7 million of right-of-use ("ROU") lease impairment expense for a facility that we vacated and impaired in the third quarter of 2020.

Non-GAAP Financial Measure

Adjusted EBITDA is a supplemental, non-GAAP financial measure.  EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization.  Adjusted EBITDA as presented also excludes restructuring charge, stock compensation expense, other income, other expense, interest income and income from equity method investment.  Adjusted EBITDA is presented below because this metric is used by the financial community as a method of measuring our financial performance and of evaluating the market value of companies considered to be in similar businesses.  Since Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, net earnings as an indicator of operating performance.  Adjusted EBITDA may not be comparable to similarly titled measures employed by other companies.  In addition, Adjusted EBITDA is not necessarily a measure of our ability to fund our cash needs.

A reconciliation by segment of loss from operations to Adjusted EBITDA follows:

(a)The Wireless segment includes acquisition expenses of $0.2 million and integration expenses of $0.3 million for the year ended September 30, 2019, related to the acquisition of Fulton (See Note 3 – Acquisition).

(b)The Telco segment includes an inventory obsolescence charge of $1.8 million and $0.7 million for the years ended September 30, 2020 and 2019, respectively.  In addition, the Telco segment includes a lower of cost or net realizable value charge of $0.1 million and $0.7 million for the years ended September 30, 2020 and 2019, respectively.

Liquidity and Capital Resources

Cash Flows Used in Operating Activities

We finance our operations through cash flows provided by operations, and our line of credit of up to $4.0 million. During 2020, cash used in operations was $3.8 million. We currently have cash of $8.4 million and availability under our bank line of credit of $0.5 million, for a total liquidity of $8.9 million. Cash used in operations during the year ended September 30, 2019 was $4.8 million.

Cash Flows Provided by Investing Activities

Capital expenditures and proceeds from asset sales are the main components of our investing activities. Cash provided by investing activities during the year ended September 30, 2020 was $2.4 million, as we received payments of $2.6 million on the note receivable related to the 2019 sale of the Cable Segment. Cash provided by investing activities during the year ended September 30, 2019 was $6.6 million, representing primarily cash proceeds from the 2019 sale of the Cable Segment, including sales of real property held in connection with Cable Segment operations

Cash Flows Provided by Financing Activities

Cash provided by financing activities during the year ended September 30, 2020 was $8.2 million, related to borrowing under the note payable, bank line of credit, proceeds from share issuances, and borrowings under the Paycheck Protection Program ("PPP," "PPP loan"). On April 14, 2020, we received a PPP loan with our primary lender for $2.9 million, bearing interest at 1% per annum, with monthly payments of principal and interest in the amount of $164,045 commencing on November 10, 2020. The loan matures on April 10, 2022. We used the proceeds from the PPP loan for payroll-related expenses in accordance with the guidelines for the loan. We have applied for forgiveness of the PPP loan in accordance with the requirements and limitations under the CARES Act, the PPP Flexibility Act and SBA regulations and requirements.

Liquidity and Capital Resources

At September 30, 2020 we had cash and equivalents and restricted cash on hand of $8.4 million and availability under our bank line of credit of $0.5 million, for a total liquidity of $8.9 million. We believe we have sufficient liquidity and capital resources to cover our operating losses and our additional working capital and debt payment needs. 

We continue to evaluate opportunities to expand our business through selective acquisitions and internal growth initiatives. Our capital investment decisions are determined by an analysis of the projected return on capital employed of each of those alternatives, which is substantially driven by the cost to acquire existing assets from a third party, the capital required to invest in new equipment and the point in the 5G densification cycle. Based on these factors, we make capital investment decisions that we believe will support our long-term growth strategy. Depending on the timing and scope of these opportunities, we may need to seek additional funding to finance the necessary working capital for such opportunities.

Critical Accounting Policies and Estimates

Note 1 to the Consolidated Financial Statements in this Form 10-K for fiscal year 2020 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 are discussed below.

Inventory Valuation

For our Telco segment, our position in the telecommunications industry requires us to carry relatively 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 telecommunication providers, telecommunication resellers, and other users of telecommunication equipment who are seeking products for which manufacturers have discontinued production or cannot ship new equipment on a same-day basis as well as providing used products as an alternative to new products from the manufacturer. Carrying these large inventory quantities represents our largest risk.

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.

Our inventories are all carried in the Telco segment and consist of new and used electronic components for the telecommunications industry. Inventory is stated at the lower of cost or net realizable value, with cost determined using the weighted-average method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  At September 30, 2020, we had total inventory, before the reserve for excess and obsolete inventories, of $8.8 million, consisting of $1.3 million in new products and $7.5 million in used or refurbished products.

We identified certain inventory that more than likely will not be sold or that the cost will not be recovered when it is processed through our recycling program.  Therefore, we have an obsolete and excess inventory reserve of $3.1 million at September 30, 2020.  In 2020, we increased the reserve by $1.8 million.  We also reviewed the cost of

14

inventories against estimated market value and recorded a lower of cost or net realizable value write-off of approximately $60 thousand for inventories that have a cost in excess of estimated net realizable value.  If actual market conditions differ from those projected by management, this could have a material impact on our gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down.

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 a material component of cost of sales.

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 $250,000 and $150,000 at September 30, 2020 and September 30, 2019, respectively. At September 30, 2020 and September 30, 2019, accounts receivable, net of allowance for doubtful accounts, were $4.0 million and $4.8 million, respectively.

Goodwill

Goodwill represents the excess of purchase price of acquisitions over the acquisition date fair value of the net identifiable tangible and intangible assets acquired. Goodwill is not amortized and is 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 each reporting unit, with the reporting unit’s carrying value, including goodwill. Our reporting units for purposes of the goodwill impairment calculation are the Wireless segment, Nave and Triton.

Management utilizes a discounted cash flow analysis to determine the estimated fair value of each reporting unit. Significant judgments and assumptions including the discount rate, anticipated revenue growth rate, gross margins and operating expenses are inherent in these fair value estimates. 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.

Due to our continued operating losses and the uncertainties surrounding the COVID-19 pandemic on the overall economy and the resulting impact on our Company, we determined that there were indicators to warrant us to test goodwill for impairment at March 31, 2020. We calculated a fair value using the income approach of both Nave and Triton to determine if the fair value exceeded their respective carrying values. For both Nave and Triton, the fair value for each was less than their respective carrying values after considering the intangible asset impairment. Therefore, we recorded an impairment charge of $4.8 million in the Telco segment as of March 31, 2020, which fully impaired goodwill for the Telco segment. Although we do not anticipate a future impairment charge, certain events could occur that might adversely affect the reported value of the remaining goodwill in the Wireless segment. Such events could include, but are not limited to, economic or competitive conditions, a significant change in technology, the economic condition of the customers and industries we serve, 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 fair value of the Wireless segment also may change.

15

Intangibles

Intangible assets that have finite useful lives are amortized on a straight-line basis over their estimated useful lives ranging from 3 to 10 years. Intangible assets are also tested for impairment when events and circumstances indicate that the carrying value may not be recoverable. Due to our continued operating losses and the uncertainties surrounding the COVID-19 pandemic on the overall economy and the resulting impact on our Company, we determined that there were indicators for us to test our intangible assets for impairment at March 31, 2020. It was determined that we needed to perform a specific fair value assessment for each of the intangible assets at both Nave and Triton as their individual undiscounted forecasted cash flows did not exceed their respective carrying values. We then performed a fair value assessment of each of the intangible assets and compared them to the individual carrying value amounts at March 31, 2020. As a result of this assessment, we recorded an impairment charge of $3.9 million related to the customer relationship intangibles in the Telco segment as of March 31, 2020. As of September 30, 2020, there were no further indicators of impairment.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable.  The Company conducts its long-lived asset impairment analyses in accordance with Accounting Standards Codification (“ASC”) 360-10-15, “Impairment or Disposal of Long-Lived Assets.”  ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows.  If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals. The Company recorded a $0.7 million impairment of a right-of-use asset in the Telco segment as of September 30, 2020, related to vacating and partially subleasing a leased facility. As of September 30, 2020, there were no further indicators of impairment.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

ADDvantage Technologies Group, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ADDvantage Technologies Group, Inc. and its subsidiaries (the Company) as of September 30, 2020 and 2019, and the related consolidated statements of operations, changes in shareholders' equity, and cash flows for the years then ended, and the related notes to the consolidated financial statements (collectively, the financial statements).  In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2020 and 2019, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these financial statements based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.  The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.  As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purposes of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.  We believe that our audits provide a reasonable basis for our opinion.

ADDvantage Technologies Group, Inc.

Notes to Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Organization and basis of presentation

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its subsidiaries, all of which are wholly owned (collectively, the “Company”).  Intercompany balances and transactions have been eliminated in consolidation.  The Company’s reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”).  The Cable Television (“Cable TV”) segment was sold on June 30, 2019, so the Company has classified the Cable TV segment as discontinued operations (see Note 4 – Discontinued Operations) in 2019.

Other reclassifications

The Company changed its presentation of cost of sales and operating, selling, general and administrative expenses on the unaudited consolidated condensed statements of operations. During fiscal year 2020, the Company reviewed its financial reporting of expenses in connection with its current operating segments in order to enhance the usefulness of the presentation of the Company’s expenses. Based on that review, the Company reclassified certain expenses into operating expenses for presentation purposes. Operating expenses include the indirect costs associated with operating our businesses. Indirect costs are costs that are not directly attributable to projects or products, which would include indirect personnel costs, facility costs, vehicles, insurance, communication, and business taxes, among other less significant cost categories. These costs were previously recorded in either costs of sales or operating, selling, general and administrative expenses in prior years. Additionally, the Company reclassified depreciation and amortization from operating, selling, general and administrative expenses into its own financial statement line item in the consolidated statements of operations. Selling, general and administrative expenses include overhead costs, which primarily consist of personnel costs, insurance, professional services, and communication, among other less significant cost categories. The prior year has been reclassified to conform with the current year’s presentation of costs of sales, operating expenses, selling, general and administrative expenses, and depreciation and amortization. These reclassifications had no effect on previously reported results of operations or retained earnings.

Cash, cash equivalents and restricted cash

Cash and cash equivalents include demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.  Restricted cash consists of cash held by a third-party financial institution as a reserve in connection with an agreement to sell certain receivables with recourse in the Wireless segment, see Note 5 - Accounts Receivable Agreements.

Revenue recognition

The Company recognizes revenue at the time a good or service is transferred to a customer and the customer, obtains control of that good or receives the service performed. Most of the Company’s sales arrangements with customers are short-term in nature involving single performance obligations related to the delivery of goods or repair of equipment and generally provide for transfer of control at the time of shipment to the customer. The Company generally permits returns of product or repaired equipment due to defects, historically, returns have not been significant.

Additionally, the Company provides services related to the installation and upgrade of technology on cell sites and the construction of new small cells for 5G technology. The work under the purchase orders for wireless infrastructure services are generally completed in less than a month. These services generally consist of a single performance obligation which the Company recognizes as revenue over time. The Company’s principal sales are from Wireless services, sales of Telco equipment and Telco recycled equipment. The Company’s customers include wireless carriers, wireless equipment providers, multiple system operators, resellers and direct sales to end-user customers.

The timing of revenue recognition from the wireless segment results in contract assets and contract liabilities. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company sometimes receives advances or deposits from customers before revenue is recognized, resulting in contract

23

liabilities. Contract assets and contract liabilities are included in Unbilled revenue and Deferred revenue, respectively, on the consolidated balance sheets.

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.

For the Company’s Wireless segment, the Company has entered into various agreements, one with recourse, to sell certain receivables to unrelated third-party financial institutions. The other agreements without recourse are under programs offered by certain customers of the Wireless segment.  The Company accounts for these transactions in accordance with Accounting Standards Codification (“ASC”) 860, “Transfers and Servicing” (“ASC 860”).  ASC 860 allows for the ownership transfer of accounts receivable to qualify for sale treatment when the appropriate criteria is met, which permits the Company to present the balances sold under the program to be excluded from accounts receivable, net on the consolidated balance sheet. Receivables are considered sold when they are transferred beyond the reach of the Company and its creditors, the purchaser has the right to pledge or exchange the receivables and the Company has surrendered control over the transferred receivables. The Company records a recourse obligation if it determines that any portion of the sold receivables with recourse are uncollectible.

Inventories

For the Telco segment, inventories consist of new, refurbished and used telecommunications equipment.  Inventory is stated at the lower of cost or net realizable value.  Cost is determined using the weighted-average method.  Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  For the Telco segment, the Company records an inventory reserve provision to reflect inventory at its estimated net 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.

Leases

The Company determines if an arrangement is a lease at inception of the arrangement. To the extent that we determine an arrangement represents a lease, we classify that lease as either a right-of-use ("ROU") lease or a finance lease. We capitalize ROU leases on our consolidated balance sheets through a right-of-use asset and a corresponding right-of-use lease liability. ROU assets represent our right to use an underlying asset for the lease term and ROU lease liabilities represent our obligation to make lease payments arising from the lease.

ROU leases are included in long-term assets and ROU lease liabilities are classified as either current or long-term liabilities in our consolidated balance sheets. ROU assets and liabilities are recognized at the commencement date of an arrangement based on the present value of lease payments over the lease term. Lease expense for ROU lease payments is recognized on a straight-line basis over the lease term. ADDvantage adopted this standard on October 1, 2019.

Property and equipment

Property and equipment consist of software, office equipment, wireless services equipment and warehouse and service equipment with estimated useful lives generally of 3 years, 5 years, 7 years, and 10 years, respectively. The wireless services equipment includes mobile wireless temporary towers, equipment trailers and construction equipment. Depreciation is provided using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the useful lives or the remainder of the lease agreement. Gains or losses from the ordinary sale or retirement of property and equipment are recorded are included in operating expense.  Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized. Depreciation expense was $0.9 million and $0.4 million for the years ended September 30, 2020 and 2019, respectively.

24

Goodwill

Goodwill represents the excess of purchase price of acquisitions over the acquisition date fair value of the net assets of businesses acquired.  Goodwill is not amortized and is tested at least annually for impairment.  The Company performs its 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 comparing the estimate of the fair value of each reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. The reporting units for purposes of the goodwill impairment calculation are aggregated into the Wireless segment and ADDvantage Triton LLC (Triton) operating segment, and Nave Communications Company (Nave) operating segment.

Management utilizes a discounted cash flow analysis to determine the estimated fair value of each reporting unit.  Significant judgments and assumptions including the discount rate, anticipated revenue growth rate, gross margins and operating expenses are inherent in these fair value estimates.  As a result, actual results may differ from the estimates utilized in the 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. 

During the year ended September 30, 2020, due to operating losses and uncertainties surrounding the impact of the COVID-19 pandemic on the overall economy and the resulting impact on the capital budgets of both Customers and our Company, we determined that impairment indicators were present. The Company performed a valuation using a discounted cash flow analysis for the Nave and Triton operating segments to determine if the fair value exceeded their respective carrying values. For both Nave and Triton, the fair value for each was less than their respective carrying values. Therefore, the Company recorded an impairment charges of $4.8 million as of March 31, 2020, which fully impaired goodwill for both operating segments in the Telco segment. Although the Company does not anticipate a future impairment charge, certain events could occur that might adversely affect the reported value of the remaining goodwill in the Wireless segment, which was $0.1 million at September 30, 2020.

Intangible assets

Intangible assets consist of customer relationships, trade names, and intellectual property. Intangibles assets that have finite useful lives are amortized on a straight-line basis over their estimated useful lives ranging from 3 years to 10 years. 

Impairment of long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 360-10-15, “Impairment or Disposal of Long-Lived Assets.” ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

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 basis 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.

Advertising costs

Advertising costs are expensed as incurred. Advertising expense was $0.5 million and $0.6 million for the years ended September 30, 2020 and 2019, respectively.

25

Management estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) 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 wireless infrastructure or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results.

Concentrations of 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 credit evaluations for all new customers but does not require collateral to support customer receivables. 

Share-based compensation

ADDvantage has historically compensated our directors and executives using time-based stock options and restricted shares awards (RSA's). ADDvantage accounts for share-based payment awards under ASC 718 - Compensation - Stock Compensation (ASC 718), which requires that the value of the awards is established at the date of the grant and is expensed over the vesting period of the grant. The method of determining the fair value of share-based payments depends on the type of award. Share-based awards that vest over a certain service period with no market conditions are valued at the closing market price on the grant date. Option grants are valued using the Black-Scholes-Merton model using model inputs that are determined on the date of the grant. Once the per-share fair value on the grant date is established, the aggregate expense of the grant is recognized on a graded vesting basis over the vesting period of the grant.

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities.

The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate.

Retirement Plan

The Company sponsors a 401(k) plan that allows participation by all employees who are at least 21 years of age and have completed one year of service. The Company's contributions to the plan consist of a matching contribution as determined by the plan document. Costs recognized under the 401(k) plan were $0.1 million and, $0.3 million for the years ended September 30, 2020 and September 30, 2019, respectively, after temporarily suspending matching contributions during 2020.

26

Recently issued accounting standards

In June 2016, the FASB issued ASU 2016-13: “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” This ASU requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. This ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal periods. ADDvantage expects to adopt the standard in the first quarter of fiscal year 2021. Management's initial evaluation is that due to the nature of our customer base, the adoption of this standard will not have a significant impact on our trade accounts receivable and contract assets.

Note 2 – Revenue Recognition

The Company’s principal sales are from Wireless services, sales of Telco equipment and Telco recycled equipment, primarily in the United States. Sales to international customers in Central and South America totaled approximately $1.9 million and $2.4 million in the years ended September 30, 2020 and 2019, respectively.

The Company’s customers include wireless carriers, wireless equipment providers, multiple system operators, resellers and direct sales to end-user customers. Sales to the Company’s largest customer totaled approximately 14% of consolidated sales.

Note 3 – 2019 Acquisition

Purchase of Net Assets of Fulton Technologies, Inc. and Mill City Communications, Inc.

On December 27, 2018, the Company entered into a purchase agreement to acquire substantially all of the net assets of Fulton Technologies, Inc. and Mill City Communications, Ins. (collectively “Fulton”).  Fulton provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.  This agreement closed on January 4, 2019.  The purchase price for the net assets of Fulton was $1.3 million.  The purchase price was allocated to the major categories of assets and liabilities based on their estimated fair values as of January 4, 2019, the effective date of the acquisition.  The Company recorded $0.1 million of Goodwill related to the acquisition.

The following summarizes the final purchase price allocation of the fair value of the assets acquired and the liabilities assumed at January 4, 2019, in thousands:

Assets acquired:
Accounts receivable	$	828

Note 4 – Discontinued Operations

In fiscal year 2018, the Board of Directors formed a committee of independent directors, referred to as the strategic direction committee, to consider, negotiate and approve or disapprove a sale transaction of the Cable TV segment ("Cable transaction") to Leveling 8, Inc. (“Leveling 8”), a company controlled by David Chymiak.  Mr. Chymiak is a director and substantial shareholder of the Company, and he was the Chief Technology Officer and President of Tulsat LLC until the closing of the sale.  After extensive due diligence efforts, in December 2018, the strategic direction committee approved and executed a stock purchase agreement of the Cable TV segment to Leveling 8, which required stockholder approval.

Shareholders voted in favor of the Cable transaction on May 29, 2019 for a selling price of $10.3 million and the sale was completed on June 30, 2019.  The purchase price consisted of $3.9 million of cash at closing (subject to a working capital adjustment estimated at $1.1 million), less the $2.1 million of cash proceeds from the sale of the Sedalia, Missouri and Warminster, Pennsylvania facilities already received (see discussion below) and a $6.4 million promissory note to be paid in semi-annual installments over five years with an interest rate of 6.0%.  The calculation of the pretax loss of the Cable transaction was as follows, in thousands:

Contract price	$	10,314
Less: Real estate sales	2,075
Less: Working capital adjustment	1,111
Net purchase price	7,128
Assets sold:
Accounts receivable	2,038
Inventories	10,259
Prepaids and other assets	73
Property and equipment, net	336
	12,706
Liabilities transferred:
Accounts payable	1,306
Accrued expenses	467
	1,773
Net assets sold	10,933
Pretax loss on sale of net assets of Cable TV segment	$	(3,805)

In addition to the real estate sold as part of the Cable transaction, the Company sold the Broken Arrow, Oklahoma facility to Mr. Chymiak, for a purchase price of $5.0 million payable in cash at closing. The sale closed on November 29, 2018, and generated a pretax gain of approximately $1.4 million.

The total pretax gain related to the sale of all real estate facilities, including the Cable transaction and the Broken Arrow facility, is as follows, in thousands:

Aggregate purchase price	$	7,075
Less: Book value of real estate facilities	4,763
Pretax gain	$	2,312

29

As a result of the Cable transaction and the three real estate facility sales to David Chymiak, the Company received total proceeds of $14.2 million and recorded a pretax loss on the sales of $1.5 million for the year ended September 30, 2019 as follows, in thousands:

Proceeds:
Cash received from real estate facility sales	$	7,075
Cash received from sale of Cable TV segment	753
Promissory note from sale of Cable TV segment	6,375
Total proceeds	14,203
Book value of assets sold:
Cable TV segment	10,932
Real estate facilities	4,763
Total book value of assets sold	15,695
Pretax loss on sale of discontinued operations	$	(1,492)

The cash received from the Cable transaction of $0.7 million resulted from the down payment of $1.8 million due at the closing less the working capital adjustment of $1.1 million. The Company received $2.6 million under the promissory note during the year ended September 30, 2020. The remaining promissory note, which is collateral under the Company's note payable with its primary lender, is scheduled to be received by the Company in semi-annual installments over five years including interest of 6% as follows, in thousands:

Fiscal year 2021	$	1,400
Fiscal year 2022	940
Fiscal year 2023	940
Fiscal year 2024	495
Total proceeds	$	3,775

The Company did not have income related to the discontinued operations during the year ended September 30, 2020. Loss from discontinued operations, net of tax and the loss on sale of discontinued operations, net of tax, of the Cable TV segment business which are presented in total as loss from discontinued operations, net of tax in the Company’s consolidated statements of operations for the year ended September 30, 2019 is as follows, in thousands:

Loss from discontinued operations, net of tax	$	(1,267)

Note 5 – Accounts Receivable Agreements

The Company’s Wireless segment has entered into various agreements, one agreement with recourse, to sell certain receivables to unrelated third-party financial institutions.  For the agreement with recourse, the Company is responsible for collecting payments on the sold receivables from its customers.  Under this agreement, the third-party financial institution advances the Company 90% of the sold receivables and establishes a reserve of 10% of the sold receivables until the Company collects the sold receivables. In addition, the third party financial institution will charge and deduct 1.6% of sold receivables. As the Company collects the sold receivables, the third-party

30

financial institution will remit the remaining 10% to the Company.  At September 30, 2020, the third-party financial institution has a reserve against the sold receivables of $0.1 million, which is reflected as restricted cash.  For the receivables sold under the agreement with recourse, the agreement addresses events and conditions which may obligate the Company to immediately repay the institution the outstanding purchase price of the receivables sold.  The total amount of receivables uncollected by the institution was $0.6 million at September 30, 2020, for which there is a limit of $3.5 million.  Although the sale of receivables is with recourse, the Company did not record a recourse obligation at September 30, 2020 as the Company determined the sold receivables are collectible.  The other agreements without recourse are under programs offered by certain customers of Fulton.

For the year ended September 30, 2020, the Company received proceeds from the sold receivables under all of their various agreements of $18.9 million and included the proceeds in net cash provided by operating activities in the consolidated statements of cash flows.  The cost of selling these receivables ranges from 1.0% to 1.8%.  The Company recorded costs of $0.3 million for the year ended September 30, 2020, in other expense in the consolidated statements of operations.

Note 6 – Inventories

Inventories, which are all within the Telco segment, at September 30, 2020 and September 30, 2019 are as follows, in thousands:

	2020		2019
New equipment	$	1,311	$	1,496
Refurbished and used equipment	7,499		7,405
Allowance for excess and obsolete inventory:	(3,054)		(1,275)
Total inventories, net	$	5,756	$	7,626

New equipment includes products purchased from manufacturers plus “surplus-new”, which are unused products purchased from other distributors or multiple system operators.  Refurbished and used equipment 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.

In the years ended September 30, 2020 and 2019, the Telco segment identified certain inventory that more than likely will not be sold or that the cost will not be recovered when it is processed through its recycling program.  Therefore, the Company has a $3.1 million allowance at September 30, 2020. The Company also reviewed the cost of inventories against estimated net realizable value and recorded a lower of cost or net realizable value charge of $1.8 million and $0.7 million for the years ended September 30, 2020 and 2019 respectively, for inventories that have a cost in excess of estimated net realizable value.

Note 7 – Intangible Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company groups assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted future cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

As a result of the Fulton acquisition, the Company recorded an additional intangible asset for customer relationships of $0.2 million, see Note 3 ‒ Acquisition. 

31

The intangible assets with their associated accumulated amortization amounts at September 30, 2020 and September 30, 2019 are as follows, in thousands:

	September 30, 2020
	Gross		Accumulated Amortization		Impairment		Net
Intangible assets:
Customer relationships – 10 years	$	8,396	$	(4,021)	$	(3,894)	$	481

Total intangible assets	$	10,892	$	(5,573)	$	(3,894)	$	1,425

	September 30, 2019
	Gross		Accumulated Amortization		Impairment		Net
Intangible assets:
Customer relationships – 10 years	$	8,396	$	(3,548)	$	—	$	4,848

Non-compete agreements – 3 years	374		(372)		—		2
Total intangible assets	$	10,889	$	(4,886)	$	—	$	6,003

As of March 31, 2020, the Company determined that changes in the economy related to the COVID-19 pandemic and the continued losses experienced in the Telco segment may cause the carrying amounts of its intangible assets to exceed their fair values. The Company performed an assessment of its intangible assets and determined that the carrying value of its customer relationships were in fact impaired based on valuation appraisals performed by the Company using a multi-period excess earnings model. Therefore, the Company recorded a $3.9 million impairment charge in the Telco segment as of March 31, 2020. As of September 30, 2020, no further indicators of potential impairment were present. Amortization expense was $0.7 million and $1.1 million for the years ended September 30, 2020 and 2019, respectively.

The estimated aggregate amortization expense for each of the next five fiscal years is as follows, in thousands:

2021	$	319
2022	319
2023	319
2024	195
2025	107

Taxes other than income tax	91		69
Interest	23		—
Other, net	443		357
Total accrued expenses	$	1,499	$	1,618

Note 9 – Debt

Loan Agreement

On March 10, 2020, the Company entered into a loan agreement with its primary lender for $3.5 million, bearing interest at 6% per annum. The loan is payable in seven semi-annual installments of principal and interest with the first payment occurring June 30, 2020, and the final payment due June 30, 2023. Payment of the loan may be accelerated in the event of a default. The principal and interest payments correlate to the payment schedule for the promissory note with Leveling 8. The balance under this loan is now $1.2 million and the final payment will be June 30, 2023. The loan is secured by substantially all of the assets of the Company, including, without limitation, the promissory note that the Company received in connection with the sale of its Cable TV segment in 2019 to Leveling 8, Inc.

Line of Credit and Notes Payable

Credit Agreement

The Company has a line of credit ("LOC") agreement with its primary lender. This credit agreement contains a $4.0 million revolving line of credit and had a maturity date of December 17, 2020. The Company renewed the line of credit for another year subsequent to September 30, 2020. During the fiscal year 2020, the line of credit required quarterly interest payments based on the prevailing Wall Street Journal Prime Rate ("WSJP") (3.25% at September 30, 2020), and the interest rate was reset monthly. The credit agreement provides that the Company maintain a fixed charge coverage ratio of not less than 1.25 to 1.00 measured annually. At September 30, 2020, the Company was not in compliance with this ratio. At September 30, 2020, there was $2.8 million outstanding under the line of credit. Future borrowings under the line of credit are limited to the lesser of $4.0 million or the sum of 80% of eligible accounts receivable and 60% of eligible Telco segment inventory. Under these limitations, the Company’s total line of credit borrowing capacity was $3.3 million at September 30, 2020, and remaining availability was $0.5 million.

Subsequent to September 30, 2020, the Company renewed its revolving bank line of credit for one year to a maturity date of December 17, 2021.  As part of this renewal, the revolving bank line of credit remained $4.0 million, or the sum of 80% of eligible accounts receivable and 25% of eligible inventory. Quarterly interest payments are based on WSJP, floating, with the addition of a 4% floor rate and a fixed charge coverage ratio of 1.25 to be tested quarterly beginning June 30, 2021.

Paycheck Protection Program Loan

On April 14, 2020, the Company received a SBA Payroll Protection Program (“PPP”) loan pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), with its primary lender for $2.9 million. The PPP loan bears interest at 1% per annum, with monthly payments of principal and interest in the amount of $164,045 commencing on November 10, 2020, and matures on April 10, 2022. The Paycheck Protection Program provides that the PPP loan may be partially or fully forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. The Company has applied for forgiveness of the PPP loan in accordance with the requirements and limitations under the CARES Act, the PPP Flexibility Act and SBA regulations and requirements.

Note 10 – Leases

ADDvantage adopted ASU No. 2016-02, Topic 842 (ASC 842) - Leases, effective October 1, 2019. This ASU requires lessees to recognize an operating lease or right-of-use ("ROU") asset and liability on the balance sheet for all right-of-use leases with an initial lease term greater than twelve months.

ASU 2018-11 Leases – Targeted Improvements, allows for a practical expedient wherein all periods previously reported under ASC 840 will continue to be reported under ASC 840, and periods beginning October 1, 2019 and after are reported under ASC 842. ADDvantage elected to adopt this practical expedient along with the package of practical expedients, which allows the Company to combine lease and non-lease costs.

Under this transition option, ADDvantage will continue to apply the legacy guidance in ASC 840, including its disclosure requirements, in the comparative periods presented and will make only annual disclosures for the comparative periods because ASC 840 does not require interim disclosures. Prior period amounts have not been adjusted and continue to be reflected in accordance with ADDvantage historical accounting. The adoption of this standard on October 1, 2019, had no impact on the Company's consolidated statement of shareholders' equity or consolidated statement of operations.

As a lessee, ADDvantage leases its corporate office headquarters in Carrollton, Texas, and conducts its business operations through various regional offices located throughout the United States. These operating locations typically

include regional offices, storage and maintenance facilities sufficient to support its operations in the area. ADDvantage leases these properties under either non-cancelable term leases many of which contain renewal options that can extend the lease term from one to five years and some of which contain escalation clauses, or month-to-month operating leases. Options to renew these leases are generally not considered reasonably certain to be exercised. Therefore, the periods covered by such optional periods are not included in the determination of the term of the lease. ADDvantage may lease equipment under cancellable short-term or contracts which are less than 30 days. Due to the nature of the Company's business, any option to renew these short-term leases is generally not considered reasonably certain to be exercised. Therefore, the periods covered by such optional periods are not included in the determination of the term of the lease, and the lease payments during these periods are similarly excluded from the calculation of right-of-use lease asset and lease liability balances.

ROU lease expense consists of rent expense related to leases that were included in ROU assets under ASC 842. ADDvantage recognizes right-of-use lease expense on a straight-line basis, except for certain variable expenses that are recognized when the variability is resolved, typically during the period in which they are paid. Variable right-of-use lease payments typically include charges for property taxes and insurance, and some leases contain variable payments related to non-lease components, including common area maintenance and usage of facilities or office equipment (for example, copiers).

As a result of adopting ASC 842, on the effective date, the Company recognized right-of-use assets and liabilities of $4.6 million, and financing lease assets and liabilities of $1.4 million. Right-of-use leases are included in right-of-use assets and current or long-term right-of-use obligations on the consolidated balance sheets. Finance leases are included in net property and equipment, and current or long-term finance lease obligations in the consolidated balance sheets.

Right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses a discount rate that approximates the rate of interest for a

34

collateralized loan over a similar term as the discount rate for present value of lease payments when the rate implicit in the contract is not readily determinable.

Impairment of right-of-use asset - The Company has a right-of-use for a building in Jessup, Maryland for Nave Communications. The Company ceased operations in Jessup, Maryland in May 2020, and vacated the Jessup, Maryland building. The building was partially subleased during fiscal year 2020. During the third quarter of 2020, the Company determined that the right-of-use asset was not recoverable and used an income approach to estimate its fair value, determining that the carrying value was partially impaired. Therefore, the Company recorded $0.7 million of impairment charges related to the lease in the Telco segment during the year ended September 30, 2020.

Note 11 – Stock-Based Compensation

Plan Information

The 2015 Incentive Stock Plan (the “Plan”) provides for awards of stock options and restricted stock to officers, directors, key employees and consultants.  Under the Plan, option prices will be set by the Compensation Committee and may not be less than the fair market value of the stock on the grant date.

At September 30, 2020, 2,100,415 shares of common stock were reserved for stock award grants under the Plan.  Of these reserved shares, 789,630 shares were available for future grants.

Stock Options

All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their grant date fair value over the requisite service period. 

36

Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of operations.

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 three, four or five years 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, 2020 and changes during the year then ended is presented below in thousands, except share and per share amounts:

The Company granted nonqualified stock options of zero and 480,000 options for the years ended September 30, 2020 and 2019, respectively. 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.

37

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 year 2019 stock option grants are as follows:

Estimated fair value of options at grant date	$196,970
Black-Scholes model assumptions:
Average expected life (years)	6
Average expected volatile factor	29%
Average risk-free interest rate	2.8%
Average expected dividend yield	—

The Company realized a net benefit related to the recognition of forfeitures of stock options during the year ended September 30, 2020. Compensation expense related to stock options recorded for the years ended September 30, 2020 and 2019 is as follows:

	2020		2019
Fiscal year 2017 grant	$	(6)	$	18
Fiscal year 2019 grant	—		128
Total compensation expense	$	(6)	$	146

At September 30, 2020, compensation costs related to these unvested stock options not yet recognized in the statements of operations was $2,945 which will be fully amortized by 2022.

Restricted stock awards

In fiscal year 2019, the Company granted restricted share awards to its Chairman of the Board of Directors totaling 55,147 shares, which were valued at market value on the date of grant. The shares will vest 20% per year with the first installment vesting on the first anniversary of the grant date. The fair value of the shares upon issuance totaled $0.1 million.

In fiscal year 2020, the Company granted a total of 298,974 shares to its board members, which were valued at market value on the date of grant. The shares ranged in vesting periods from immediate to three years. The fair value of the shares upon issuance totaled $0.6 million.

In fiscal year 2020, the Company granted a total of 220,937 shares to certain members of management, which were valued at market value on the date of grant. The shares ranged in vesting periods from immediate to three years. The fair value of the shares upon issuance totaled $0.6 million.

A summary of the Company's non-vested restricted share awards (RSA) at September 30, 2020 and changes during the year ended September 30, 2020 is presented in the following table:

	Shares	Fair Value
Non-vested at September 30, 2019	44,118	$	60
Granted	764,184	1,569
Vested	(333,278)	(571)
Forfeited	—	—
Non-vested at September 30, 2020	475,024	$	1,058

In addition, certain outstanding stock options held by two members of management and one director were converted to stock grants based on a fair value calculation of the outstanding stock options. As a result, the options outstanding, which totaled 330,000 options, were forfeited and 244,273 shares of common stock were granted based on the fair value calculation of $0.6 million. Since this was considered a modification of a stock award, the Company recognized the difference between the stock grant fair value and the immediate fair value of the stock option award, before modification which totaled $0.2 million.

38

Compensation expense related to restricted stock recorded for the years ended September 30, 2020 and 2019 is as follows, in thousands:

	2020		2019
Fiscal year 2019 grant	15		38
Fiscal year 2020 grant	565		15
Total compensation expense	$	580	$	53

Valuation of time vesting restricted stock awards for all periods presented is equal to the quoted market price for the shares on the date of the grant. The Company amortizes the fair value of the restricted share awards, graded, over the vesting period of the awards.

Note 12 – Equity Distribution Agreement and Sale of Common Stock

On April 24, 2020, the Company entered into an Equity Distribution Agreement (the “Sales Agreement”) with Northland Securities, Inc., as agent (“Northland”), pursuant to which the Company may offer and sell, from time to time, through Northland, shares of the Company’s common stock, par value $0.01 per share, having an aggregate offering price of up to $13.9 million.

The charges without tax benefit rate includes, among other things, the impact of officer life insurance, nondeductible meals and entertainment and permanent basis differences in goodwill.

As a result of the CARES Act, the Company can carryback net operating losses (NOL) generated in 2018 through 2020 for a period of five years. As a result, the Company’s effective tax rate included an income tax benefit recognized during the fiscal year ended September 30, 2020 related to tax losses generated during the fiscal year up to the amount that the Company estimates is realizable based upon taxable income in the carryback periods. Therefore, as of September 30, 2020, the Company recorded a $1.2 million income tax receivable and a corresponding current benefit for income taxes. The Company continues to provide a valuation allowance of $6.4 million for all net deferred tax assets where the Company believes it is more likely than not that those deferred taxes will not be realized.

The tax effects of temporary differences related to deferred taxes at September 30, 2020 and 2019 consist of the following, in thousands:

Year ended September 30, 2018	$	2,431,000	No expiry
Year ended September 30, 2016	$	82,820	2036

41

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 recent cumulative losses, that it is more likely than not that the Company will not be able to realize the full effect of the deferred tax assets and a valuation allowance of $6.4 million 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 2017.

Note 16 – Segment Reporting

The Company is reporting its financial performance based on its external reporting segments: Wireless Infrastructure Services and Telecommunications.  These reportable segments are described below.

Wireless Infrastructure Services (“Wireless”) On January 4, 2019, the Company purchased substantially all of the net assets of Fulton, which comprises the Wireless segment.  Fulton provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers that support these wireless carriers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.

Telecommunications (“Telco”) The Company’s Telco segment sells new and refurbished telecommunications networking equipment, including both central office and customer premise equipment, to its customer base of telecommunications providers, enterprise customers and resellers located primarily in North America.  This segment also offers its customers repair and testing services for telecommunications networking equipment. In addition, this segment offers its customers decommissioning services for surplus and obsolete equipment, which it in turn processes through its recycling program.

The Company evaluates performance and allocates its resources based on operating income. The accounting policies of its reportable segments are the same as those described in the summary of significant accounting policies. Segment assets consist primarily of cash and cash equivalents, accounts receivable, inventory, property and equipment, goodwill and intangible assets.

Changes in Internal Control Over Financial Reporting

During the year ended September 30, 2020, the Company completed the full integration of Fulton Technologies, Inc., into our internal control over financial reporting processes.

Other than the changes described above, during the most recent fiscal year, there have been no changes, including the impact of COVID-19, in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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

43

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, 2020. 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, 2020. 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 (2013).

During fiscal year 2019, the Company acquired Fulton. See Note 3. Acquisitions for additional information on this acquisition. Management has included this business in its evaluation of the effectiveness of the Company’s internal control over financial reporting as of September 30, 2020. 

Based on our assessment, we believe that, as of September 30, 2020, our internal control over financial reporting is effective.

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 year ended September 30, 2020, the Company integrated the acquisition of Fulton Technologies, Inc. fully into its control environment.

										Non-Equity
						Stock		Option		Incentive Plan		All Other		Total
	Name and Principal Position	Year	Salary		Bonus	Awards		Awards		Compensation		Compensation		Compensation
			($)(1)		($)(2)	($) (3)		($) (4)		($)		($)(5)		($)

	Vice President, Chief Accounting Officer	2019	182,885		—	—		11,220		—		15,144		209,249

	President, Telco Segment (6)	2019	210,769		—	—		18,700		—		16,538		246,007
(1)	Messrs. Hart and Francis are entitled to the compensation under employment or severance agreements which are described below.
(2)	Bonus amounts paid in 2020 represent amounts earned in 2019. There was no executive bonus awarded in 2020. There were no 2019 bonus payments related to 2018.
(3)	The amounts shown are Company officer compensation and represent the total fair value of the stock awards shares on the date of the grant to officers for fiscal years 2020 and 2019. The fair value of the stock awards is amortized over the vesting period to compensation expense in the Consolidated Statements of Operations contained in this Annual Report on Form 10-K. The fair value of the stock awards was based on the closing market prices of the stock on the dates of the grants. The actual value that an executive officer will realize upon vesting of performance or time-based awards will depend upon the market price of the Company’s stock on the vesting date, so there is no assurance that the value realized by an executive officer will be at or near the value of the market price of the Company’s stock on the grant date. In addition, certain outstanding stock options held by Mr. Hart and Mr. Francis were converted to stock grants based on a the fair value of the outstanding stock options on the conversion date. As a result, the options were forfeited and the officer's compensation is shown net of the value of the forfeited options.
(4)	The amounts shown represent expenses recognized in the Consolidated Financial Statements contained in the Part II of the Company’s Annual Report on Form 10-K for the year ended September 30, 2020. All assumptions utilized to calculate the expense amounts shown above are set forth in Note 11 - Stock Based Compensation of the Notes to Consolidated Financial Statements in Part II of this Annual Report on From 10-K.
(5)	Represents amounts paid by the Company on behalf of an officer for matching contributions to the Company’s qualified 401(k) plan, and auto allowance received during the year. Mr. Kinison's other compensation includes $67,700 of severance and $28,300 of COBRA payments.
(6)	Mr. Kinison's salary for 2020 prorated based on his departure from the Company on May 31, 2020, and includes payout of unused vacation time at separation.

Potential Payments Upon Termination or Change of Control

We have entered into employment/severance agreements with Mr. Hart and Mr. Francis. These agreements are designed to promote stability, continuity and focus for key members of leadership during periods of uncertainty that may be created by change of control situations. Additionally, the use of such agreements is a competitive practice that enhances our ability to attract and retain leadership talent.

Under these agreements, payment of benefits will occur in most situations where the employee is terminated without cause or is terminated or resigns in connection with a Change in Control of the Company. Mr. Hart, in this event, will be paid the amount of his annual base salary immediately preceding the termination without cause or Change of Control and Mr. Francis will be paid the amount of 50% of his annual base salary immediately preceding the termination without cause or Change of Control. Most executive equity awards which are subject to vesting provide for accelerated vesting upon the occurrence of a change in control. Mr. Kinison was a party to a similar employment agreement prior to his departure from the Company.

“Change of Control” as used in these agreements has a fairly customary definition designed to reflect that a fundamental change in beneficial ownership or control of the Company has occurred. Specifically, the agreements incorporate the term a “change of control event”, as defined in United States Treasury Regulations (“Regulations”) promulgated under section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) that results from an event in which a person comes to be the owner, directly or indirectly, of 50% or more of outstanding voting

49

securities of the Company or its parent company or the transfer or disposition of all or substantially all of the assets of the Company, its parent or their successor or a person, acquires, directly or indirectly, the voting power to elect a majority of the members of the Board of the Company or its parent (other than in the normal course) or any other similar transaction or series of related transactions.

Outstanding Equity Awards at September 30, 2020

The named executive officers of the Company did not have any unvested equity awards as of September 30, 2020.

Compensation of Directors

We paid our non-employee directors $500 per quarter and $750 for each board meeting and $375 for each committee meeting or telephonic board or committee meeting the director attended. The chairman of the Audit Committee receives an additional $375 per meeting, and the chairmen of the Compensation and Governance and Nominating Committees receive an additional $150 per meeting. In addition, all directors are eligible to receive awards of restricted shares, which are subject to a 12-month holding period, or options to purchase shares of our common stock each year after the annual shareholders meeting. We reimburse all directors for out-of-pocket expenses incurred by them in connection with their service on our Board and any Board committee. The following table reflects the total compensation earned by each non-employee director during the last fiscal year:

The grant was for 8,287 shares using the closing stock price on the date of the 2019 annual meeting of shareholders.

Dear _____:

1.    Restricted Stock Award. ADDvantage Technologies Group, Inc., an Oklahoma corporation (the “Company”), is pleased to grant to you an aggregate of ______ shares of Common Stock, par value $0.01 per share, of the Company (the “Restricted Shares”). This award is subject to your acceptance of and agreement to all of the applicable terms, conditions, and restrictions described in the Company’s 2015 Incentive Stock Plan, as amended (the “Plan”), and to your acceptance of and agreement to the further terms, conditions, and restrictions described in this Restricted Stock Award Agreement (this “Award Agreement”). To the extent that any provision of this Award Agreement conflicts with the expressly applicable terms of the Plan, it is hereby acknowledged and agreed that those terms of the Plan shall control and, if necessary, the applicable provisions of this Award Agreement shall be hereby deemed amended so as to carry out the purpose and intent of the Plan.

2.    Possession of Certificates. The Company shall, at its option, (i) issue a certificate or certificates for the Restricted Shares in your name and shall retain the certificate(s) for the period during which the restrictions described in Section 4(b) are in effect or (ii) issue instructions to the Company’s agent for the book entry of your ownership of the Restricted Shares in uncertificated form. You shall execute and deliver to the Company a stock power or stock powers or power of attorney or like form in blank for the Restricted Shares. You hereby agree that the Company shall hold the certificate(s) for the Restricted Shares and the related stock power(s) and shall retain control over uncertificated Restricted Shares pursuant to the terms of this Award Agreement until such time as the restrictions described in Section 4(b) lapse as described in Section 5 or the Restricted Shares are canceled pursuant to the terms of Section 4(b).

3.    Ownership of Restricted Shares. You shall be entitled to all the rights of absolute ownership of the Restricted Shares, including the right to vote such shares and to receive dividends therefrom if, as, and when declared by the Company’s Board of Directors, subject, however, to the terms, conditions, and restrictions described in the Plan and in this Award Agreement.

4.    Restrictions.

(a)    Your ownership of the Restricted Shares shall be subject to the restrictions set forth in subsection (b) of this Section until the Restricted Shares vest pursuant to the terms of Section 5, at which time the Restricted Shares shall be yours.

Page 2

(b)    The restrictions referred to in subsection (a) of this Section are as follows:

(1)    You shall forfeit the Restricted Shares to the Company and all of your rights thereto shall terminate without any payment of consideration by the Company if your “Termination of Employment” (as defined below) occurs prior to vesting of the Restricted Shares under Section 5. If you forfeit any Restricted Shares and your interest therein terminates pursuant to this paragraph, such Restricted Shares shall be canceled. “Termination of Employment” shall mean when such individual is no longer serving as an employee of the Company for any reason, including termination with or without cause, or resignation but shall not include a termination occurring by reason of death or Disability.

(2)    Until vesting under Section 5, you may not sell, assign, transfer, pledge, hypothecate, or otherwise dispose of the Restricted Shares.

5.    Vesting.

(a)    Subject to Section 4, you shares will vest (i) _________ percent (__%) of the Restricted Shares on the first anniversary; (ii) ________ percent (__%) of the Restricted Shares on the second anniversary of the date of this Agreement; and (iii) the balance of the Restricted Shares on the third anniversary of the date of this Agreement. 1 Restricted Shares as to which you are vested shall no longer be considered “Restricted Shares” and shall no longer be subject to the restrictions described in this Agreement, including without limitation, Section 4(b).

(b)    In addition to vesting under Section 4(a), you shall vest with respect to all the Restricted Shares at the time of the occurrence of any of the following events:

(1)    Your death or “Disability” (as defined in the Plan); or

(2)    A “Change of Control” (as defined in the Plan) of the Company.

    6.    Agreement With Respect to Taxes; Share Withholding.

(a)    You agree that (1) you will pay to the Company or a Subsidiary, as the case may be, or make arrangements satisfactory to the Company or such Subsidiary regarding the payment of any foreign, federal, state, or local taxes of any kind required by law to be withheld by the Company or any of its Subsidiaries with respect to the Restricted Shares, and (2) the Company or any of its Subsidiaries shall, to the extent permitted by law, have the right to deduct from any payments of any kind otherwise due to you any foreign, federal, state, or local taxes of any kind required by law to be withheld with respect to the Restricted Shares.

(b)    With respect to withholding required upon the lapse of restrictions or upon any other taxable event arising as a result of the Restricted Shares awarded, you may

1 Conform vesting provisions to those approved by compensation committee or other governing body or person.

Page 3

elect, subject to the approval of the committee of the Board of Directors of the Company that administers the Plan, to satisfy the withholding requirement, in whole or in part, by forfeiting and having the Company cancel Restricted Shares having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be withheld on the transaction. All such elections shall be irrevocable, made in writing, signed by you, and shall be subject to any restrictions or limitations that such committee, in its sole discretion, deems appropriate. You should discuss with your tax advisor the advantages and disadvantages of making the election described in this paragraph.

7.    Adjustment of Shares. The number of Restricted Shares subject to this Award Agreement shall be adjusted as provided in Article 13 of the Plan. Any shares or other securities received by you as a stock dividend on, or as a result of stock splits, combinations, exchanges of shares, reorganizations, mergers, consolidations or otherwise with respect to the Restricted Shares shall have the same terms, conditions and restrictions and bear the same legend as the Restricted Shares.

8.    Agreement With Respect to Securities Matters. You agree that you will not sell or otherwise transfer any Restricted Shares except pursuant to an effective registration statement under the U.S. Securities Act of 1933, as amended, or pursuant to an applicable exemption from such registration.

9.    Certain Definitions. Capitalized terms used in this Award Agreement and not otherwise defined herein shall have the respective meanings provided in the Plan.

10.     Section 83(b) Election. Under current general tax rules, you will be taxed on the value of your Restricted Shares when the restrictions lapse in accordance with Section 5 of this Agreement. You can elect instead to be taxed on the value of the Restricted Shares on the date of this award. You should discuss with your tax advisor the possible tax advantages and disadvantages of making this so-called “Section 83(b) election”. A copy of the election form, which must be filed with the IRS within thirty days after the grant date of your Restricted Stock, is attached to this Agreement. You should talk to your tax advisor about the filing procedures and deadline.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Organization and basis of presentation

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its subsidiaries, all of which are wholly owned (collectively, the “Company”).  Intercompany balances and transactions have been eliminated in consolidation.  The Company’s reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”).  The Cable Television (“Cable TV”) segment was sold on June 30, 2019, so the Company has classified the Cable TV segment as discontinued operations (see Note 4 – Discontinued Operations) in 2019.

Other reclassifications

The Company changed its presentation of cost of sales and operating, selling, general and administrative expenses on the unaudited consolidated condensed statements of operations. During fiscal year 2020, the Company reviewed its financial reporting of expenses in connection with its current operating segments in order to enhance the usefulness of the presentation of the Company’s expenses. Based on that review, the Company reclassified certain expenses into operating expenses for presentation purposes. Operating expenses include the indirect costs associated with operating our businesses. Indirect costs are costs that are not directly attributable to projects or products, which would include indirect personnel costs, facility costs, vehicles, insurance, communication, and business taxes, among other less significant cost categories. These costs were previously recorded in either costs of sales or operating, selling, general and administrative expenses in prior years. Additionally, the Company reclassified depreciation and amortization from operating, selling, general and administrative expenses into its own financial statement line item in the consolidated statements of operations. Selling, general and administrative expenses include overhead costs, which primarily consist of personnel costs, insurance, professional services, and communication, among other less significant cost categories. The prior year has been reclassified to conform with the current year’s presentation of costs of sales, operating expenses, selling, general and administrative expenses, and depreciation and amortization. These reclassifications had no effect on previously reported results of operations or retained earnings.

Cash, cash equivalents and restricted cash

Cash and cash equivalents include demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.  Restricted cash consists of cash held by a third-party financial institution as a reserve in connection with an agreement to sell certain receivables with recourse in the Wireless segment, see Note 5 - Accounts Receivable Agreements.

Revenue recognition

The Company recognizes revenue at the time a good or service is transferred to a customer and the customer, obtains control of that good or receives the service performed. Most of the Company’s sales arrangements with customers are short-term in nature involving single performance obligations related to the delivery of goods or repair of equipment and generally provide for transfer of control at the time of shipment to the customer. The Company generally permits returns of product or repaired equipment due to defects, historically, returns have not been significant.

Additionally, the Company provides services related to the installation and upgrade of technology on cell sites and the construction of new small cells for 5G technology. The work under the purchase orders for wireless infrastructure services are generally completed in less than a month. These services generally consist of a single performance obligation which the Company recognizes as revenue over time. The Company’s principal sales are from Wireless services, sales of Telco equipment and Telco recycled equipment. The Company’s customers include wireless carriers, wireless equipment providers, multiple system operators, resellers and direct sales to end-user customers.

The timing of revenue recognition from the wireless segment results in contract assets and contract liabilities. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company sometimes receives advances or deposits from customers before revenue is recognized, resulting in contract

liabilities. Contract assets and contract liabilities are included in Unbilled revenue and Deferred revenue, respectively, on the consolidated balance sheets.

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.

For the Company’s Wireless segment, the Company has entered into various agreements, one with recourse, to sell certain receivables to unrelated third-party financial institutions. The other agreements without recourse are under programs offered by certain customers of the Wireless segment.  The Company accounts for these transactions in accordance with Accounting Standards Codification (“ASC”) 860, “Transfers and Servicing” (“ASC 860”).  ASC 860 allows for the ownership transfer of accounts receivable to qualify for sale treatment when the appropriate criteria is met, which permits the Company to present the balances sold under the program to be excluded from accounts receivable, net on the consolidated balance sheet. Receivables are considered sold when they are transferred beyond the reach of the Company and its creditors, the purchaser has the right to pledge or exchange the receivables and the Company has surrendered control over the transferred receivables. The Company records a recourse obligation if it determines that any portion of the sold receivables with recourse are uncollectible.

Inventories

For the Telco segment, inventories consist of new, refurbished and used telecommunications equipment.  Inventory is stated at the lower of cost or net realizable value.  Cost is determined using the weighted-average method.  Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  For the Telco segment, the Company records an inventory reserve provision to reflect inventory at its estimated net 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.

Leases

The Company determines if an arrangement is a lease at inception of the arrangement. To the extent that we determine an arrangement represents a lease, we classify that lease as either a right-of-use ("ROU") lease or a finance lease. We capitalize ROU leases on our consolidated balance sheets through a right-of-use asset and a corresponding right-of-use lease liability. ROU assets represent our right to use an underlying asset for the lease term and ROU lease liabilities represent our obligation to make lease payments arising from the lease.

ROU leases are included in long-term assets and ROU lease liabilities are classified as either current or long-term liabilities in our consolidated balance sheets. ROU assets and liabilities are recognized at the commencement date of an arrangement based on the present value of lease payments over the lease term. Lease expense for ROU lease payments is recognized on a straight-line basis over the lease term. ADDvantage adopted this standard on October 1, 2019.

Property and equipment

Property and equipment consist of software, office equipment, wireless services equipment and warehouse and service equipment with estimated useful lives generally of 3 years, 5 years, 7 years, and 10 years, respectively. The wireless services equipment includes mobile wireless temporary towers, equipment trailers and construction equipment. Depreciation is provided using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the useful lives or the remainder of the lease agreement. Gains or losses from the ordinary sale or retirement of property and equipment are recorded are included in operating expense.  Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized. Depreciation expense was $0.9 million and $0.4 million for the years ended September 30, 2020 and 2019, respectively.

Goodwill

Goodwill represents the excess of purchase price of acquisitions over the acquisition date fair value of the net assets of businesses acquired.  Goodwill is not amortized and is tested at least annually for impairment.  The Company performs its 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 comparing the estimate of the fair value of each reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. The reporting units for purposes of the goodwill impairment calculation are aggregated into the Wireless segment and ADDvantage Triton LLC (Triton) operating segment, and Nave Communications Company (Nave) operating segment.

Management utilizes a discounted cash flow analysis to determine the estimated fair value of each reporting unit.  Significant judgments and assumptions including the discount rate, anticipated revenue growth rate, gross margins and operating expenses are inherent in these fair value estimates.  As a result, actual results may differ from the estimates utilized in the 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. 

During the year ended September 30, 2020, due to operating losses and uncertainties surrounding the impact of the COVID-19 pandemic on the overall economy and the resulting impact on the capital budgets of both Customers and our Company, we determined that impairment indicators were present. The Company performed a valuation using a discounted cash flow analysis for the Nave and Triton operating segments to determine if the fair value exceeded their respective carrying values. For both Nave and Triton, the fair value for each was less than their respective carrying values. Therefore, the Company recorded an impairment charges of $4.8 million as of March 31, 2020, which fully impaired goodwill for both operating segments in the Telco segment. Although the Company does not anticipate a future impairment charge, certain events could occur that might adversely affect the reported value of the remaining goodwill in the Wireless segment, which was $0.1 million at September 30, 2020.

Intangible assets

Intangible assets consist of customer relationships, trade names, and intellectual property. Intangibles assets that have finite useful lives are amortized on a straight-line basis over their estimated useful lives ranging from 3 years to 10 years. 

Impairment of long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 360-10-15, “Impairment or Disposal of Long-Lived Assets.” ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

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 basis 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.

Advertising costs

Advertising costs are expensed as incurred. Advertising expense was $0.5 million and $0.6 million for the years ended September 30, 2020 and 2019, respectively.

Management estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) 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 wireless infrastructure or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results.

Concentrations of 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 credit evaluations for all new customers but does not require collateral to support customer receivables. 

Share-based compensation

ADDvantage has historically compensated our directors and executives using time-based stock options and restricted shares awards (RSA's). ADDvantage accounts for share-based payment awards under ASC 718 - Compensation - Stock Compensation (ASC 718), which requires that the value of the awards is established at the date of the grant and is expensed over the vesting period of the grant. The method of determining the fair value of share-based payments depends on the type of award. Share-based awards that vest over a certain service period with no market conditions are valued at the closing market price on the grant date. Option grants are valued using the Black-Scholes-Merton model using model inputs that are determined on the date of the grant. Once the per-share fair value on the grant date is established, the aggregate expense of the grant is recognized on a graded vesting basis over the vesting period of the grant.

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities.

The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate.

Retirement Plan

The Company sponsors a 401(k) plan that allows participation by all employees who are at least 21 years of age and have completed one year of service. The Company's contributions to the plan consist of a matching contribution as determined by the plan document. Costs recognized under the 401(k) plan were $0.1 million and, $0.3 million for the years ended September 30, 2020 and September 30, 2019, respectively, after temporarily suspending matching contributions during 2020.

Recently issued accounting standards

In June 2016, the FASB issued ASU 2016-13: “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” This ASU requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. This ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal periods. ADDvantage expects to adopt the standard in the first quarter of fiscal year 2021. Management's initial evaluation is that due to the nature of our customer base, the adoption of this standard will not have a significant impact on our trade accounts receivable and contract assets.

2019 Acquisition

Purchase of Net Assets of Fulton Technologies, Inc. and Mill City Communications, Inc.

On December 27, 2018, the Company entered into a purchase agreement to acquire substantially all of the net assets of Fulton Technologies, Inc. and Mill City Communications, Ins. (collectively “Fulton”).  Fulton provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.  This agreement closed on January 4, 2019.  The purchase price for the net assets of Fulton was $1.3 million.  The purchase price was allocated to the major categories of assets and liabilities based on their estimated fair values as of January 4, 2019, the effective date of the acquisition.  The Company recorded $0.1 million of Goodwill related to the acquisition.

The following summarizes the final purchase price allocation of the fair value of the assets acquired and the liabilities assumed at January 4, 2019, in thousands:

Discontinued Operations

Discontinued Operations

In fiscal year 2018, the Board of Directors formed a committee of independent directors, referred to as the strategic direction committee, to consider, negotiate and approve or disapprove a sale transaction of the Cable TV segment ("Cable transaction") to Leveling 8, Inc. (“Leveling 8”), a company controlled by David Chymiak.  Mr. Chymiak is a director and substantial shareholder of the Company, and he was the Chief Technology Officer and President of Tulsat LLC until the closing of the sale.  After extensive due diligence efforts, in December 2018, the strategic direction committee approved and executed a stock purchase agreement of the Cable TV segment to Leveling 8, which required stockholder approval.

Shareholders voted in favor of the Cable transaction on May 29, 2019 for a selling price of $10.3 million and the sale was completed on June 30, 2019.  The purchase price consisted of $3.9 million of cash at closing (subject to a working capital adjustment estimated at $1.1 million), less the $2.1 million of cash proceeds from the sale of the Sedalia, Missouri and Warminster, Pennsylvania facilities already received (see discussion below) and a $6.4 million promissory note to be paid in semi-annual installments over five years with an interest rate of 6.0%.  The calculation of the pretax loss of the Cable transaction was as follows, in thousands:

Contract price	$	10,314
Less: Real estate sales	2,075
Less: Working capital adjustment	1,111
Net purchase price	7,128

In addition to the real estate sold as part of the Cable transaction, the Company sold the Broken Arrow, Oklahoma facility to Mr. Chymiak, for a purchase price of $5.0 million payable in cash at closing. The sale closed on November 29, 2018, and generated a pretax gain of approximately $1.4 million.

The total pretax gain related to the sale of all real estate facilities, including the Cable transaction and the Broken Arrow facility, is as follows, in thousands:

Aggregate purchase price	$	7,075
Less: Book value of real estate facilities	4,763
Pretax gain	$	2,312

As a result of the Cable transaction and the three real estate facility sales to David Chymiak, the Company received total proceeds of $14.2 million and recorded a pretax loss on the sales of $1.5 million for the year ended September 30, 2019 as follows, in thousands:

Proceeds:
Cash received from real estate facility sales	$	7,075
Cash received from sale of Cable TV segment	753

Cable TV segment	10,932
Real estate facilities	4,763
Total book value of assets sold	15,695
Pretax loss on sale of discontinued operations	$	(1,492)

The cash received from the Cable transaction of $0.7 million resulted from the down payment of $1.8 million due at the closing less the working capital adjustment of $1.1 million. The Company received $2.6 million under the promissory note during the year ended September 30, 2020. The remaining promissory note, which is collateral under the Company's note payable with its primary lender, is scheduled to be received by the Company in semi-annual installments over five years including interest of 6% as follows, in thousands:

Receivables [Abstract]

Accounts Receivable Agreements

Accounts Receivable AgreementsThe Company’s Wireless segment has entered into various agreements, one agreement with recourse, to sell certain receivables to unrelated third-party financial institutions.  For the agreement with recourse, the Company is responsible for collecting payments on the sold receivables from its customers.  Under this agreement, the third-party financial institution advances the Company 90% of the sold receivables and establishes a reserve of 10% of the sold receivables until the Company collects the sold receivables. In addition, the third party financial institution will charge and deduct 1.6% of sold receivables. As the Company collects the sold receivables, the third-party

financial institution will remit the remaining 10% to the Company.  At September 30, 2020, the third-party financial institution has a reserve against the sold receivables of $0.1 million, which is reflected as restricted cash.  For the receivables sold under the agreement with recourse, the agreement addresses events and conditions which may obligate the Company to immediately repay the institution the outstanding purchase price of the receivables sold.  The total amount of receivables uncollected by the institution was $0.6 million at September 30, 2020, for which there is a limit of $3.5 million.  Although the sale of receivables is with recourse, the Company did not record a recourse obligation at September 30, 2020 as the Company determined the sold receivables are collectible.  The other agreements without recourse are under programs offered by certain customers of Fulton.

For the year ended September 30, 2020, the Company received proceeds from the sold receivables under all of their various agreements of $18.9 million and included the proceeds in net cash provided by operating activities in the consolidated statements of cash flows.  The cost of selling these receivables ranges from 1.0% to 1.8%.  The Company recorded costs of $0.3 million for the year ended September 30, 2020, in other expense in the consolidated statements of operations.

Allowance for excess and obsolete inventory:	(3,054)		(1,275)
Total inventories, net	$	5,756	$	7,626

New equipment includes products purchased from manufacturers plus “surplus-new”, which are unused products purchased from other distributors or multiple system operators.  Refurbished and used equipment 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.

In the years ended September 30, 2020 and 2019, the Telco segment identified certain inventory that more than likely will not be sold or that the cost will not be recovered when it is processed through its recycling program.  Therefore, the Company has a $3.1 million allowance at September 30, 2020. The Company also reviewed the cost of inventories against estimated net realizable value and recorded a lower of cost or net realizable value charge of $1.8 million and $0.7 million for the years ended September 30, 2020 and 2019 respectively, for inventories that have a cost in excess of estimated net realizable value.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets

Intangible Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company groups assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted future cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

As a result of the Fulton acquisition, the Company recorded an additional intangible asset for customer relationships of $0.2 million, see Note 3 ‒ Acquisition. 

The intangible assets with their associated accumulated amortization amounts at September 30, 2020 and September 30, 2019 are as follows, in thousands:

As of March 31, 2020, the Company determined that changes in the economy related to the COVID-19 pandemic and the continued losses experienced in the Telco segment may cause the carrying amounts of its intangible assets to exceed their fair values. The Company performed an assessment of its intangible assets and determined that the carrying value of its customer relationships were in fact impaired based on valuation appraisals performed by the Company using a multi-period excess earnings model. Therefore, the Company recorded a $3.9 million impairment charge in the Telco segment as of March 31, 2020. As of September 30, 2020, no further indicators of potential impairment were present. Amortization expense was $0.7 million and $1.1 million for the years ended September 30, 2020 and 2019, respectively.

Debt

Loan Agreement

On March 10, 2020, the Company entered into a loan agreement with its primary lender for $3.5 million, bearing interest at 6% per annum. The loan is payable in seven semi-annual installments of principal and interest with the first payment occurring June 30, 2020, and the final payment due June 30, 2023. Payment of the loan may be accelerated in the event of a default. The principal and interest payments correlate to the payment schedule for the promissory note with Leveling 8. The balance under this loan is now $1.2 million and the final payment will be June 30, 2023. The loan is secured by substantially all of the assets of the Company, including, without limitation, the promissory note that the Company received in connection with the sale of its Cable TV segment in 2019 to Leveling 8, Inc.

Line of Credit and Notes Payable

Credit Agreement

The Company has a line of credit ("LOC") agreement with its primary lender. This credit agreement contains a $4.0 million revolving line of credit and had a maturity date of December 17, 2020. The Company renewed the line of credit for another year subsequent to September 30, 2020. During the fiscal year 2020, the line of credit required quarterly interest payments based on the prevailing Wall Street Journal Prime Rate ("WSJP") (3.25% at September 30, 2020), and the interest rate was reset monthly. The credit agreement provides that the Company maintain a fixed charge coverage ratio of not less than 1.25 to 1.00 measured annually. At September 30, 2020, the Company was not in compliance with this ratio. At September 30, 2020, there was $2.8 million outstanding under the line of credit. Future borrowings under the line of credit are limited to the lesser of $4.0 million or the sum of 80% of eligible accounts receivable and 60% of eligible Telco segment inventory. Under these limitations, the Company’s total line of credit borrowing capacity was $3.3 million at September 30, 2020, and remaining availability was $0.5 million.

Subsequent to September 30, 2020, the Company renewed its revolving bank line of credit for one year to a maturity date of December 17, 2021.  As part of this renewal, the revolving bank line of credit remained $4.0 million, or the sum of 80% of eligible accounts receivable and 25% of eligible inventory. Quarterly interest payments are based on WSJP, floating, with the addition of a 4% floor rate and a fixed charge coverage ratio of 1.25 to be tested quarterly beginning June 30, 2021.

Paycheck Protection Program Loan

On April 14, 2020, the Company received a SBA Payroll Protection Program (“PPP”) loan pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), with its primary lender for $2.9 million. The PPP loan bears interest at 1% per annum, with monthly payments of principal and interest in the amount of $164,045 commencing on November 10, 2020, and matures on April 10, 2022. The Paycheck Protection Program provides that the PPP loan may be partially or fully forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. The Company has applied for forgiveness of the PPP loan in accordance with the requirements and limitations under the CARES Act, the PPP Flexibility Act and SBA regulations and requirements.

Leases [Abstract]

Leases

Leases

ADDvantage adopted ASU No. 2016-02, Topic 842 (ASC 842) - Leases, effective October 1, 2019. This ASU requires lessees to recognize an operating lease or right-of-use ("ROU") asset and liability on the balance sheet for all right-of-use leases with an initial lease term greater than twelve months.

ASU 2018-11 Leases – Targeted Improvements, allows for a practical expedient wherein all periods previously reported under ASC 840 will continue to be reported under ASC 840, and periods beginning October 1, 2019 and after are reported under ASC 842. ADDvantage elected to adopt this practical expedient along with the package of practical expedients, which allows the Company to combine lease and non-lease costs.

Under this transition option, ADDvantage will continue to apply the legacy guidance in ASC 840, including its disclosure requirements, in the comparative periods presented and will make only annual disclosures for the comparative periods because ASC 840 does not require interim disclosures. Prior period amounts have not been adjusted and continue to be reflected in accordance with ADDvantage historical accounting. The adoption of this standard on October 1, 2019, had no impact on the Company's consolidated statement of shareholders' equity or consolidated statement of operations.

As a lessee, ADDvantage leases its corporate office headquarters in Carrollton, Texas, and conducts its business operations through various regional offices located throughout the United States. These operating locations typically

include regional offices, storage and maintenance facilities sufficient to support its operations in the area. ADDvantage leases these properties under either non-cancelable term leases many of which contain renewal options that can extend the lease term from one to five years and some of which contain escalation clauses, or month-to-month operating leases. Options to renew these leases are generally not considered reasonably certain to be exercised. Therefore, the periods covered by such optional periods are not included in the determination of the term of the lease. ADDvantage may lease equipment under cancellable short-term or contracts which are less than 30 days. Due to the nature of the Company's business, any option to renew these short-term leases is generally not considered reasonably certain to be exercised. Therefore, the periods covered by such optional periods are not included in the determination of the term of the lease, and the lease payments during these periods are similarly excluded from the calculation of right-of-use lease asset and lease liability balances.

ROU lease expense consists of rent expense related to leases that were included in ROU assets under ASC 842. ADDvantage recognizes right-of-use lease expense on a straight-line basis, except for certain variable expenses that are recognized when the variability is resolved, typically during the period in which they are paid. Variable right-of-use lease payments typically include charges for property taxes and insurance, and some leases contain variable payments related to non-lease components, including common area maintenance and usage of facilities or office equipment (for example, copiers).

As a result of adopting ASC 842, on the effective date, the Company recognized right-of-use assets and liabilities of $4.6 million, and financing lease assets and liabilities of $1.4 million. Right-of-use leases are included in right-of-use assets and current or long-term right-of-use obligations on the consolidated balance sheets. Finance leases are included in net property and equipment, and current or long-term finance lease obligations in the consolidated balance sheets.

Right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses a discount rate that approximates the rate of interest for a

collateralized loan over a similar term as the discount rate for present value of lease payments when the rate implicit in the contract is not readily determinable.

Impairment of right-of-use asset - The Company has a right-of-use for a building in Jessup, Maryland for Nave Communications. The Company ceased operations in Jessup, Maryland in May 2020, and vacated the Jessup, Maryland building. The building was partially subleased during fiscal year 2020. During the third quarter of 2020, the Company determined that the right-of-use asset was not recoverable and used an income approach to estimate its fair value, determining that the carrying value was partially impaired. Therefore, the Company recorded $0.7 million of impairment charges related to the lease in the Telco segment during the year ended September 30, 2020.

Stock-based Compensation

12 Months Ended

Sep. 30, 2020

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

Plan Information

The 2015 Incentive Stock Plan (the “Plan”) provides for awards of stock options and restricted stock to officers, directors, key employees and consultants.  Under the Plan, option prices will be set by the Compensation Committee and may not be less than the fair market value of the stock on the grant date.

At September 30, 2020, 2,100,415 shares of common stock were reserved for stock award grants under the Plan.  Of these reserved shares, 789,630 shares were available for future grants.

Stock Options

All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated 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 operations.

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 three, four or five years 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, 2020 and changes during the year then ended is presented below in thousands, except share and per share amounts:

The Company granted nonqualified stock options of zero and 480,000 options for the years ended September 30, 2020 and 2019, respectively. 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 year 2019 stock option grants are as follows:

Estimated fair value of options at grant date	$196,970
Black-Scholes model assumptions:
Average expected life (years)	6
Average expected volatile factor	29%
Average risk-free interest rate	2.8%
Average expected dividend yield	—

The Company realized a net benefit related to the recognition of forfeitures of stock options during the year ended September 30, 2020. Compensation expense related to stock options recorded for the years ended September 30, 2020 and 2019 is as follows:

	2020		2019
Fiscal year 2017 grant	$	(6)	$	18
Fiscal year 2019 grant	—		128
Total compensation expense	$	(6)	$	146

At September 30, 2020, compensation costs related to these unvested stock options not yet recognized in the statements of operations was $2,945 which will be fully amortized by 2022.

Restricted stock awards

In fiscal year 2019, the Company granted restricted share awards to its Chairman of the Board of Directors totaling 55,147 shares, which were valued at market value on the date of grant. The shares will vest 20% per year with the first installment vesting on the first anniversary of the grant date. The fair value of the shares upon issuance totaled $0.1 million.

In fiscal year 2020, the Company granted a total of 298,974 shares to its board members, which were valued at market value on the date of grant. The shares ranged in vesting periods from immediate to three years. The fair value of the shares upon issuance totaled $0.6 million.

In fiscal year 2020, the Company granted a total of 220,937 shares to certain members of management, which were valued at market value on the date of grant. The shares ranged in vesting periods from immediate to three years. The fair value of the shares upon issuance totaled $0.6 million.

A summary of the Company's non-vested restricted share awards (RSA) at September 30, 2020 and changes during the year ended September 30, 2020 is presented in the following table:

	Shares	Fair Value
Non-vested at September 30, 2019	44,118	$	60
Granted	764,184	1,569
Vested	(333,278)	(571)
Forfeited	—	—
Non-vested at September 30, 2020	475,024	$	1,058

In addition, certain outstanding stock options held by two members of management and one director were converted to stock grants based on a fair value calculation of the outstanding stock options. As a result, the options outstanding, which totaled 330,000 options, were forfeited and 244,273 shares of common stock were granted based on the fair value calculation of $0.6 million. Since this was considered a modification of a stock award, the Company recognized the difference between the stock grant fair value and the immediate fair value of the stock option award, before modification which totaled $0.2 million.

Compensation expense related to restricted stock recorded for the years ended September 30, 2020 and 2019 is as follows, in thousands:

	2020		2019
Fiscal year 2019 grant	15		38
Fiscal year 2020 grant	565		15
Total compensation expense	$	580	$	53

Valuation of time vesting restricted stock awards for all periods presented is equal to the quoted market price for the shares on the date of the grant. The Company amortizes the fair value of the restricted share awards, graded, over the vesting period of the awards.

The following table summarizes the differences between the U.S. federal statutory rate and the Company’s effective tax rate for continuing operations financial statement purposes for the years ended September 30, 2020 and 2019:

	2020		2019
Statutory tax rate	21.0	%	21.0	%

Company’s effective tax rate	6.6	%	0.3	%

The charges without tax benefit rate includes, among other things, the impact of officer life insurance, nondeductible meals and entertainment and permanent basis differences in goodwill.

As a result of the CARES Act, the Company can carryback net operating losses (NOL) generated in 2018 through 2020 for a period of five years. As a result, the Company’s effective tax rate included an income tax benefit recognized during the fiscal year ended September 30, 2020 related to tax losses generated during the fiscal year up to the amount that the Company estimates is realizable based upon taxable income in the carryback periods. Therefore, as of September 30, 2020, the Company recorded a $1.2 million income tax receivable and a corresponding current benefit for income taxes. The Company continues to provide a valuation allowance of $6.4 million for all net deferred tax assets where the Company believes it is more likely than not that those deferred taxes will not be realized.

The tax effects of temporary differences related to deferred taxes at September 30, 2020 and 2019 consist of the following, in thousands:

Year ended September 30, 2018	$	2,431,000	No expiry
Year ended September 30, 2016	$	82,820	2036

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 recent cumulative losses, that it is more likely than not that the Company will not be able to realize the full effect of the deferred tax assets and a valuation allowance of $6.4 million 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 2017.

Segment Reporting

The Company is reporting its financial performance based on its external reporting segments: Wireless Infrastructure Services and Telecommunications.  These reportable segments are described below.

Wireless Infrastructure Services (“Wireless”) On January 4, 2019, the Company purchased substantially all of the net assets of Fulton, which comprises the Wireless segment.  Fulton provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers that support these wireless carriers.  These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G.

Telecommunications (“Telco”) The Company’s Telco segment sells new and refurbished telecommunications networking equipment, including both central office and customer premise equipment, to its customer base of telecommunications providers, enterprise customers and resellers located primarily in North America.  This segment also offers its customers repair and testing services for telecommunications networking equipment. In addition, this segment offers its customers decommissioning services for surplus and obsolete equipment, which it in turn processes through its recycling program.

The Company evaluates performance and allocates its resources based on operating income. The accounting policies of its reportable segments are the same as those described in the summary of significant accounting policies. Segment assets consist primarily of cash and cash equivalents, accounts receivable, inventory, property and equipment, goodwill and intangible assets.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Sep. 30, 2020

Accounting Policies [Abstract]

Organization and basis of presentation

Organization and basis of presentation

The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its subsidiaries, all of which are wholly owned (collectively, the “Company”).  Intercompany balances and transactions have been eliminated in consolidation.  The Company’s reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”).  The Cable Television (“Cable TV”) segment was sold on June 30, 2019, so the Company has classified the Cable TV segment as discontinued operations (see Note 4 – Discontinued Operations) in 2019.

Other reclassifications

The Company changed its presentation of cost of sales and operating, selling, general and administrative expenses on the unaudited consolidated condensed statements of operations. During fiscal year 2020, the Company reviewed its financial reporting of expenses in connection with its current operating segments in order to enhance the usefulness of the presentation of the Company’s expenses. Based on that review, the Company reclassified certain expenses into operating expenses for presentation purposes. Operating expenses include the indirect costs associated with operating our businesses. Indirect costs are costs that are not directly attributable to projects or products, which would include indirect personnel costs, facility costs, vehicles, insurance, communication, and business taxes, among other less significant cost categories. These costs were previously recorded in either costs of sales or operating, selling, general and administrative expenses in prior years. Additionally, the Company reclassified depreciation and amortization from operating, selling, general and administrative expenses into its own financial statement line item in the consolidated statements of operations. Selling, general and administrative expenses include overhead costs, which primarily consist of personnel costs, insurance, professional services, and communication, among other less significant cost categories. The prior year has been reclassified to conform with the current year’s presentation of costs of sales, operating expenses, selling, general and administrative expenses, and depreciation and amortization. These reclassifications had no effect on previously reported results of operations or retained earnings.

Cash, cash equivalents and restricted cash

Cash, cash equivalents and restricted cash

Cash and cash equivalents include demand and time deposits, money market funds and other marketable securities with maturities of three months or less when acquired.  Restricted cash consists of cash held by a third-party financial institution as a reserve in connection with an agreement to sell certain receivables with recourse in the Wireless segment, see Note 5 - Accounts Receivable Agreements.

Revenue recognition

The Company recognizes revenue at the time a good or service is transferred to a customer and the customer, obtains control of that good or receives the service performed. Most of the Company’s sales arrangements with customers are short-term in nature involving single performance obligations related to the delivery of goods or repair of equipment and generally provide for transfer of control at the time of shipment to the customer. The Company generally permits returns of product or repaired equipment due to defects, historically, returns have not been significant.

Additionally, the Company provides services related to the installation and upgrade of technology on cell sites and the construction of new small cells for 5G technology. The work under the purchase orders for wireless infrastructure services are generally completed in less than a month. These services generally consist of a single performance obligation which the Company recognizes as revenue over time. The Company’s principal sales are from Wireless services, sales of Telco equipment and Telco recycled equipment. The Company’s customers include wireless carriers, wireless equipment providers, multiple system operators, resellers and direct sales to end-user customers.

The timing of revenue recognition from the wireless segment results in contract assets and contract liabilities. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company sometimes receives advances or deposits from customers before revenue is recognized, resulting in contract

liabilities. Contract assets and contract liabilities are included in Unbilled revenue and Deferred revenue, respectively, on the consolidated balance sheets.

Accounts receivable

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.

For the Company’s Wireless segment, the Company has entered into various agreements, one with recourse, to sell certain receivables to unrelated third-party financial institutions. The other agreements without recourse are under programs offered by certain customers of the Wireless segment.  The Company accounts for these transactions in accordance with Accounting Standards Codification (“ASC”) 860, “Transfers and Servicing” (“ASC 860”).  ASC 860 allows for the ownership transfer of accounts receivable to qualify for sale treatment when the appropriate criteria is met, which permits the Company to present the balances sold under the program to be excluded from accounts receivable, net on the consolidated balance sheet. Receivables are considered sold when they are transferred beyond the reach of the Company and its creditors, the purchaser has the right to pledge or exchange the receivables and the Company has surrendered control over the transferred receivables. The Company records a recourse obligation if it determines that any portion of the sold receivables with recourse are uncollectible.

Inventories

Inventories

For the Telco segment, inventories consist of new, refurbished and used telecommunications equipment.  Inventory is stated at the lower of cost or net realizable value.  Cost is determined using the weighted-average method.  Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  For the Telco segment, the Company records an inventory reserve provision to reflect inventory at its estimated net 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.

Leases

Leases

The Company determines if an arrangement is a lease at inception of the arrangement. To the extent that we determine an arrangement represents a lease, we classify that lease as either a right-of-use ("ROU") lease or a finance lease. We capitalize ROU leases on our consolidated balance sheets through a right-of-use asset and a corresponding right-of-use lease liability. ROU assets represent our right to use an underlying asset for the lease term and ROU lease liabilities represent our obligation to make lease payments arising from the lease.

ROU leases are included in long-term assets and ROU lease liabilities are classified as either current or long-term liabilities in our consolidated balance sheets. ROU assets and liabilities are recognized at the commencement date of an arrangement based on the present value of lease payments over the lease term. Lease expense for ROU lease payments is recognized on a straight-line basis over the lease term. ADDvantage adopted this standard on October 1, 2019.

Property and equipment

Property and equipment

Property and equipment consist of software, office equipment, wireless services equipment and warehouse and service equipment with estimated useful lives generally of 3 years, 5 years, 7 years, and 10 years, respectively. The wireless services equipment includes mobile wireless temporary towers, equipment trailers and construction equipment. Depreciation is provided using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the useful lives or the remainder of the lease agreement. Gains or losses from the ordinary sale or retirement of property and equipment are recorded are included in operating expense.  Repairs and maintenance costs are generally expensed as incurred, whereas major improvements are capitalized. Depreciation expense was $0.9 million and $0.4 million for the years ended September 30, 2020 and 2019, respectively.

Goodwill

Goodwill

Goodwill represents the excess of purchase price of acquisitions over the acquisition date fair value of the net assets of businesses acquired.  Goodwill is not amortized and is tested at least annually for impairment.  The Company performs its 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 comparing the estimate of the fair value of each reporting unit, or operating segment, with the reporting unit’s carrying value, including goodwill. The reporting units for purposes of the goodwill impairment calculation are aggregated into the Wireless segment and ADDvantage Triton LLC (Triton) operating segment, and Nave Communications Company (Nave) operating segment.

Management utilizes a discounted cash flow analysis to determine the estimated fair value of each reporting unit.  Significant judgments and assumptions including the discount rate, anticipated revenue growth rate, gross margins and operating expenses are inherent in these fair value estimates.  As a result, actual results may differ from the estimates utilized in the 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. 

During the year ended September 30, 2020, due to operating losses and uncertainties surrounding the impact of the COVID-19 pandemic on the overall economy and the resulting impact on the capital budgets of both Customers and our Company, we determined that impairment indicators were present. The Company performed a valuation using a discounted cash flow analysis for the Nave and Triton operating segments to determine if the fair value exceeded their respective carrying values. For both Nave and Triton, the fair value for each was less than their respective carrying values. Therefore, the Company recorded an impairment charges of $4.8 million as of March 31, 2020, which fully impaired goodwill for both operating segments in the Telco segment. Although the Company does not anticipate a future impairment charge, certain events could occur that might adversely affect the reported value of the remaining goodwill in the Wireless segment, which was $0.1 million at September 30, 2020.

Intangible assets

Intangible assetsIntangible assets consist of customer relationships, trade names, and intellectual property. Intangibles assets that have finite useful lives are amortized on a straight-line basis over their estimated useful lives ranging from 3 years to 10 years.

Impairment of long-lived assets

Impairment of long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 360-10-15, “Impairment or Disposal of Long-Lived Assets.” ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.

Income taxes

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 basis 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.

Advertising costs

Advertising costs

Advertising costs are expensed as incurred. Advertising expense was $0.5 million and $0.6 million for the years ended September 30, 2020 and 2019, respectively.

Management estimates

Management estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) 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 wireless infrastructure or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results.

Concentrations of risk

Concentrations of 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 credit evaluations for all new customers but does not require collateral to support customer receivables.

Share-based compensation

Share-based compensation

ADDvantage has historically compensated our directors and executives using time-based stock options and restricted shares awards (RSA's). ADDvantage accounts for share-based payment awards under ASC 718 - Compensation - Stock Compensation (ASC 718), which requires that the value of the awards is established at the date of the grant and is expensed over the vesting period of the grant. The method of determining the fair value of share-based payments depends on the type of award. Share-based awards that vest over a certain service period with no market conditions are valued at the closing market price on the grant date. Option grants are valued using the Black-Scholes-Merton model using model inputs that are determined on the date of the grant. Once the per-share fair value on the grant date is established, the aggregate expense of the grant is recognized on a graded vesting basis over the vesting period of the grant.

Fair value of financial instruments

Fair value of financial instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities.

The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate.

Retirement Plan

The Company sponsors a 401(k) plan that allows participation by all employees who are at least 21 years of age and have completed one year of service. The Company's contributions to the plan consist of a matching contribution as determined by the plan document. Costs recognized under the 401(k) plan were $0.1 million and, $0.3 million for the years ended September 30, 2020 and September 30, 2019, respectively, after temporarily suspending matching contributions during 2020.

Recently issued accounting standards

ecently issued accounting standardsIn June 2016, the FASB issued ASU 2016-13: “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” This ASU requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. This ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal periods. ADDvantage expects to adopt the standard in the first quarter of fiscal year 2021. Management's initial evaluation is that due to the nature of our customer base, the adoption of this standard will not have a significant impact on our trade accounts receivable and contract assets.
