NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


Note 1 - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with accounting principles generally accepted in the United
States for interim financial statements and do not include all information and
footnotes required by generally accepted accounting principles for complete
financial statements. However, the information furnished reflects all
adjustments, consisting only of normal recurring items which are, in the
opinion of management, necessary in order to make the financial statements not
misleading.  The consolidated financial statements as of September 30, 2005
have been audited by independent certified public accountants.  It is suggested
that these consolidated financial statements be read in conjunction with the
financial statements and the notes thereto included in the Company's Annual
Report on Form 10-K for the fiscal year ended September 30, 2005.


Note 2 - Description of Business

ADDvantage Technologies Group, Inc., through its subsidiaries Tulsat,
Tulsat-Nebraska, Inc., NCS Industries, Inc., ADDvantage Technologies Group of
Missouri, Inc., ADDvantage Technologies Group of Texas, Tulsat-Atlanta, LLC,
and Jones Broadband International, Inc, (collectively, the "Company"), sells
new, surplus, and refurbished cable television equipment throughout North
America and Latin America in addition to being a repair center for various
cable companies.  The Company operates in one business segment.


Note 3 - Earnings per Share

Basic and diluted net earnings per share were computed in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share."  Basic net earnings per share is computed by dividing net earnings
available to common shareholders (numerator) by the weighted average number of
common shares outstanding (denominator) during the period and excludes the
dilutive effect of stock options.  Diluted net earnings per share gives effect
to all dilutive potential common shares outstanding during a period.  In
computing diluted net earnings per share, the average stock price for the
period is used in determining the number of shares assumed to be reacquired
under the treasury stock method from the exercise of stock options.

Note 4 - Line of Credit, Stockholder Loans, and Notes Payable

At December 31, 2005, a $3,312,632 balance is outstanding under a $7.0 million
line of credit due September 30, 2006, with interest payable monthly based on
the prevailing 30-day LIBOR rate plus 2.0% (6.4% at December 31, 2005).  At
December 31, 2005, $3,687,368 was available for borrowing under the line of
credit.

Cash receipts are applied from the Company's lockbox account directly against
the bank line of credit, and checks clearing the bank are funded from the line
of credit.  The resulting overdraft balance, consisting of outstanding checks,
was $43,783 at December 31, 2005, and is included in the bank revolving line of
credit.

An $8 million amortizing term note with Bank of Oklahoma was obtained to
finance the redemption of the outstanding shares of the Series A Convertible
Preferred Stock at September 30, 2004.  The outstanding balance on this note
was $6.5 million at December 31, 2005.  The note is due on September 30, 2009,
with monthly principal payments of $100,000 plus accrued interest, and the note
bears interest at the prevailing 30-day LIBOR rate plus 2.50% (6.9% at
December 31, 2005). An interest rate swap was entered into simultaneously with
the note on September 30, 2004, which fixed the interest rate at 6.13%.  Upon
entering into this interest rate swap, the Company designated this derivative
as a cash flow hedge by documenting our risk management objective and strategy

                                     -8-

for undertaking the hedge along with methods for assessing the swap's
effectiveness.  At December 31, 2005, the fair market value of the interest
rate swap approximated its carrying value of $167,812.  Notes payable secured
by real estate of $337,663 are due in monthly payments through 2013 with
interest at 5.5% through 2008, converting thereafter to prime minus .25%.

Note 5 - Stock Option Plans

Effective October 1, 2005, the Company adopted SFAS 123R which requires all
share-based payments to employees, including grants of employee stock options,
to be recognized in the financial statements based on their grant date fair
market values. On October 1, 2005, all outstanding options representing 144,767
shares were fully vested.   Therefore, the adoption of SFAS 123R had no impact
on the Company's results of operations.  Employees exercised 2,750 shares
during the quarter ended December 31, 2005, and no new options were granted.


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Overview

We are a Value Added Reseller ("VAR") for selected Scientific-Atlanta and
Motorola broadband new products.  We also specialize in the sale of
refurbished, previously-owned cable television ("CATV") equipment to CATV
operators and other broadband communication companies.  Within the last three
years, we have become distributors for several different manufacturers of
equipment and other related products.  It is through our development of these
relationships that that we have focused our initiative to market our products
and services to the larger cable multiple system operators ("MSOs").  As a
result, our overall sales increased for the first three months of fiscal 2006.
We continue to believe that as cable companies look at expanding their services
in key markets and to remain competitive during this period of economic
recovery, there will be an emphasis on minimizing their costs, thus creating a
higher demand for our repair services and surplus-new equipment.

Results of Operations

Comparison of Results of Operations for the Three Months Ended
- --------------------------------------------------------------
December 31, 2005 and December 31, 2004
- ---------------------------------------

Net Sales.  Net sales increased $2.5 million, or 20.3%, to $14.8 million in the
first quarter of fiscal 2006, from $12.3 million for the same period in fiscal
2005, primarily due to the positive results of our marketing initiatives and
distributor relationships discussed in the previous paragraph.  New equipment
sales were up 19.5% to $10.6 million for the current period, compared with
$8.9 million for the same period of fiscal 2005.  Sales of remanufactured
equipment increased 27.0% to $2.8 million for the current period, compared
with $2.2 million in the same period last year.  Repair service revenues were
up 6.1% to $1.21 million for the current quarter, compared with $1.14 million
for the same period last year.  The acquisition of Jones Broadband accounted
for 26.3% of the total net sales increase and all of  the repair income
increase.

Cost of Sales.  Cost of sales includes (i) the cost of new and refurbished
equipment, on a weighted average cost basis, sold during the period, (ii) the
equipment cost used in repairs, (iii) the related transportation cost, and (iv)
the labor and overhead directly related to these sales.  Cost of sales

                                     -9-

increased to $9.7 million for the first quarter of fiscal 2006 from $8.2
million for the same period of fiscal 2005.  The increase was primarily due to
the increase in sales for the period and the Jones Broadband acquisition, which
was responsible for 20.5% of increased cost of sales. Cost of sales for new and
refurbished equipment decreased slightly to 65.2% of net sales income for 2006
from 66.3% of net sales income for 2005.  Cost of sales for repair services
decreased to 70.1% of net service income for 2006 from 72.7% of net service
income for 2005.

Gross Profit.  Gross profit climbed $1.0 million, or 25.0%, to $5.1 million for
the first quarter of fiscal 2006 from $4.1 million for the same period in
fiscal 2005.  The gross margin percentage was 34.4% for the current quarter,
compared to 33.1% for the same quarter last year.  The percentage increase was
primarily due to the increase in sales described above.

Operating, Selling, General and Administrative Expenses.  Operating, selling,
general and administrative expenses include all personnel costs, including
fringe benefits, insurance and taxes, occupancy, transportation (other than
freight-in), communication and professional services, among other less
significant accounts.  Operating, selling, general and administrative expenses
increased by $620,000 in the first quarter of fiscal 2006, to $2.13 million
from $1.51 million for the same period in 2005, an increase of 41.0%.  Over
half of the increase was due to increased operating costs associated with the
Jones Broadband acquisition in August of 2005.  The additional increase was due
to increased expenses related to the growth of the Company's sales and related
activities.

Income from Operations.  Income from operations rose $405,000, or 16.3%, to
$2.9 million for the first quarter of fiscal 2006 from $2.5 million for the
same period last year.  This increase was primarily due to increases in sales,
partially offset by the increase in operating costs.

Income Taxes.  The provision for income taxes for fiscal 2006 increased to
$1,005,000 from $828,000 in fiscal 2005.  This increase was due to higher
pre-tax earnings in fiscal 2006.

Critical Accounting Policies


     Note 1 to the Consolidated Financial Statements in Form 10-K for fiscal
year 2005 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 accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting periods. 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 may differ from these
estimates under different assumptions or conditions. The most significant
estimates and assumptions relate to the carrying value of our inventory and, to
a lesser extent, the adequacy of our allowance for doubtful accounts.

                                    -10-


     Inventory Valuation
     -------------------

     Inventory consists of new and used electronic components for the cable
television industry.  Inventory is stated at the lower of cost or market.
Market is defined principally as net realizable value.  Cost is determined
using the weighted average method.

      We market our products primarily to MSOs and other users of cable
television equipment who are seeking products of which manufacturers have
discontinued production, or are seeking shipment on a same-day basis.  Our
position in the industry requires us to carry large inventory quantities
relative to quarterly sales, but also allows us to realize high overall gross
profit margins on our sales.   Carrying these large inventories represents our
largest risk.  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 we are able to make in a
reasonable period.  Over the past two years, our investment in inventory has
shifted to become predominantly new products purchased from manufacturers and
"surplus-new" products, which are unused products purchased from other
distributors or MSOs.

    In order to address the risks associated with our investment in inventory,
we regularly review inventory quantities on hand and reduce the carrying value
by recording a provision for excess and obsolete inventory based primarily on
inventory aging and forecasts of product demand and pricing.  The broadband
industry is characterized by changing customer demands and changes in
technology that could result in significant increases or decreases of inventory
pricing or increases in excess or obsolete quantities on hand.  Our estimates
of future product demand may prove to be inaccurate; in which case the
provision required for excess and obsolete inventory may have been understated
or overstated.  Although every effort is made to ensure the accuracy of
internal forecasting, any significant changes in demand or prices could have a
significant impact on the carrying value of our inventory and reported
operating results.  Demand for some of the items in our inventory has been
impacted by recent economic conditions present in the cable industry.  No
change to the allowance for excess or obsolete inventory was recorded during
the quarter ended December 31, 2005.

     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 creditworthiness, current economic trends and changes
in our customer payment terms. Significant changes in customer concentration or
payment terms, deterioration of customer creditworthiness, or weakening in
economic trends could have a significant impact on the collectibility 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, additional allowances may be required.  At December 31, 2005,
accounts receivable, net of allowance for doubtful accounts of $222,000,
amounted to $6.5 million.  The $130,000 increase in the doubtful accounts,
during the first fiscal quarter ended December 31, 2005, is based on the
analysis of a few of the Company's customers' change in paying habits.

     Stock-based Compensation
     ------------------------

In December  2004, the FASB issued SFAS 123R, which replaced SFAS 123 and
superseded APB 25. SFAS 123R requires all share-based payments to employees,
including grants of employee stock options, to be recognized in the financial
statements based on their grant date fair market values  and requires that such
recognition begin in the first interim or annual period after June 15, 2005,

                                    -11-

with early adoption encouraged. In April 2005, the Securities and Exchange
Commission (the SEC) postponed the effective date of SFAS 123R until the
issuer's first fiscal year beginning after June 15, 2005.  Under SFAS 123R,
the pro forma disclosures previously permitted no longer will be an alternative
to financial statement recognition. We adopted SFAS 123R effective
October 1, 2005, and will apply the Black-Scholes valuation model in
determining the fair value of share-based payments to employees, which will
then be amortized on a straight line basis over the requisite service period.
We will apply the modified prospective method, which requires that compensation
expense be recorded for all unvested stock options and restricted stock upon
adoption of SFAS 123R.  On October 1, 2005, all outstanding options
representing 144,767 shares were fully vested. Employees exercised 2,750 shares
during the quarter ended December 31, 2005 and no new options were granted.

Liquidity and Capital Resources

     We have a line of credit with the Bank of Oklahoma under which we are
authorized to borrow up to $7.0 million at a borrowing rate based on the
prevailing 30-day LIBOR rate plus 2.0% (6.4% at December 31, 2005.)  This line
of credit will provide the lesser of $7.0 million or the sum of 80% of
qualified accounts receivable and 50% of qualified inventory in a revolving
line of credit for working capital purposes.  At December 31, 2005,
$3,687,368 was available for borrowing under the line of credit.  The line of
credit is collateralized by inventory, accounts receivable, equipment and
fixtures, and general intangibles and had an outstanding balance at
December 31, 2005, of $3.3 million, due September 30, 2006.  We intend to
renew the agreement at the maturity date under similar terms.

     An $8 million amortizing term note with Bank of Oklahoma was obtained to
finance the redemption of the outstanding shares of our Series A Convertible
Preferred Stock at September 30, 2004.  The outstanding balance on this note
was $6.5 million at December 31, 2005.  The note is due on September 30, 2009,
with monthly principal payments of $100,000 plus accrued interest, and the note
bears interest at the prevailing 30-day LIBOR rate plus 2.50% (6.9% at
December 31, 2005).  An interest rate swap was entered into simultaneously with
the note on September 30, 2004, which fixed the interest rate at 6.13%.  Notes
payable secured by real estate of $337,663 are due in monthly payments through
2013 with interest at 5.5% through 2008, converting thereafter to prime minus
..25%.

     We finance our operations primarily through internally generated funds and
the bank line of credit.  Monthly minimum payments of principal for notes
payable and loans used to purchase buildings will be slightly over $1.2 million
in the next 12 months.  We expect to fund these payments through cash flows
from operations.

Forward Looking Statements

     Certain statements included in this report which are not historical facts
are forward-looking statements. These forward-looking statements are based on
current expectations, estimates, assumptions and beliefs of management; and
words such as "expects," "anticipates," "intends," "plans," "believes,"
"projects," "estimates" and similar expressions are intended to identify such
forward-looking statements. These forward-looking statements involve risks and
uncertainties, including, but not limited to, the future prospects for our
business, our ability to generate or to raise sufficient capital to allow it to
make additional business acquisitions, changes or developments in the cable
television business that could adversely affect our business or operations, the
continued availability to us of our key management personnel, general economic
conditions, the availability of new and used equipment and other inventory and
our ability to fund the costs thereof, and other factors which may affect our

                                    -12-

ability to comply with future obligations. Accordingly, actual results may
differ materially from those expressed in the forward-looking statements.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     The Company's exposure to market rate risk for changes in interest rates
relates primarily to its revolving line of credit.  The interest rates under
the line of credit fluctuate with the LIBOR rate.  At December 31, 2005, the
outstanding balances subject to variable interest rate fluctuations totaled
$3.3 million.  Future changes in interest rates could cause our borrowing costs
to increase or decrease.

     The Company maintains no cash equivalents.  However, the Company entered
into an interest rate swap on September 30, 2004, in an amount equivalent to
the $8 million note payable in order to minimize interest rate risk.  Although
the note bears interest at the prevailing 30-day LIBOR rate plus 2.50%, the
swap effectively fixed the interest rate at 6.13%.  The fair value of this
derivative, $167,812 at December 31, 2005, will increase or decrease opposite
any future changes in interest rates. All sales and purchases are denominated
in U.S. dollars.

Item 4.  Controls and Procedures

     Based on his evaluation, our Chief Executive Officer and Chief Financial
Officer has concluded that, subject to the following sentence, our disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act) as of the end of the period covered by this report on Form 10-Q
are effective to ensure that information required to be disclosed by us in
reports that we file or submit under the Exchange Act are recorded, processed,
summarized and reported within the time periods specified in Securities and
Exchange Commission rules and forms.  We plan to implement increased education
of relevant personnel of the timing requirements for the reports required under
the Exchange Act and to adopt procedures which should result in better
coordination between our personnel responsible for reporting and our securities
counsel.

     During the period covered by this report on Form 10-Q, there have been no
changes in our internal control over financial reporting that have materially
affected or are reasonably likely to materially affect our internal control
over financial reporting.

        CERTIFICATION OF CHIEF EXECUTIVE OFFICER AND CHIEF FINANCIAL
     OFFICER PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Kenneth A. Chymiak, certify that:

1.     I have reviewed this quarterly report on Form 10-Q of ADDvantage
    Technologies Group, Inc.;

2.     Based on my knowledge, this report does not contain any untrue statement
    of a material fact or omit to state a material fact necessary to make the
    statements made, in light of the circumstances under which such statements
    were made, not misleading with respect to the period covered by this
    report;

3.     Based on my knowledge, the financial statements, and other financial
    information included in this report, fairly present in all material
    respects the financial condition, results of operations and cash flows of
    the registrant as of, and for, the periods presented in this report;

4.     I am responsible for establishing and maintaining disclosure controls
    and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15-(e))
    for the registrant and have:

    a. Designed such disclosure controls and procedures, or caused such
       disclosure controls and procedures to be designed under my supervision,
       to ensure that material information relating to the registrant,
       including its consolidated subsidiaries, is made known to me by others
       within those entities, particularly during the period in which this
       report is being prepared;

    b. Evaluated the effectiveness of the registrant's disclosure controls and
       procedures and presented in this report my conclusions about the
       effectiveness of the disclosure controls and procedures, as of the end
       of the period covered by this report based on such evaluation; and

    c. Disclosed in this report any change in the registrant's internal control
       over financial reporting that occurred during the registrant's most
       recent fiscal quarter (the registrant's fourth fiscal quarter in the
       case of an annual report) that has materially affected, or is reasonably
       likely to materially affect, the registrant's internal control over
       financial reporting; and

5.     I have disclosed, based on my most recent evaluation of internal control
    over financial reporting, to the registrant's auditors and the audit
    committee of the registrant's board of directors (or persons performing the
    equivalent functions):

    a. All significant deficiencies and material weaknesses in the design or
       operation of internal control over financial reporting which are
       reasonably likely to adversely affect the registrant's ability to
       record, process, summarize and report financial information; and

    b. Any fraud, whether or not material, that involves management or other
       employees who have a significant role in the registrant's internal
       control over financial reporting.
