                                     ------

ITEM 1. BUSINESS
----------------

General Development of Business
-------------------------------

         Hickok Incorporated was organized in 1915 as an Ohio corporation, and
first offered its securities to the public in 1959. Except as otherwise stated,
the terms "Company" or "Hickok" as used herein mean Hickok Incorporated and its
two wholly-owned subsidiaries.

         In February 1995 the shareholders approved a change in the Company's
name to Hickok Incorporated from The Hickok Electrical Instrument Company. The
former name was not representative of the Company's current products and markets
and may have conveyed an inaccurate image of the Company to customers, prospects
and investors.

         Hickok develops and manufactures products used by companies in the
transportation industry. Primary markets served are automotive, aircraft, and
locomotive with sales to both original equipment manufacturers (OEM's) and to
the aftermarket.

         For many years the Company sold precision indicating instruments for
aircraft, locomotive and general industrial applications. Within the past ten
years the Company has used this expertise to develop and manufacture electronic
diagnostic equipment used by automotive technicians in the automotive market.
This is now the Company's largest business segment.

         The Company's first major product in the automotive diagnostic market
was the New Generation Star ("NGS") tester sold to Ford Motor Company. The
product was introduced in the early 1990's and was very successful though it
resulted in Hickok becoming very dependent on a single customer. Product and
customer diversification efforts were initiated in 1993 to reduce this
dependence. Acquisitions were used as the primary solution.


                                       2
<PAGE>   3

         The Company has made three acquisitions in the last six fiscal years as
part of a strategic program to expand both its customer base and its product
line utilizing its existing expertise. A new product primarily for the
automotive market was added in February, 1994 when the Company acquired the
fastening systems business from Allen-Bradley Company, Inc. The fastening
business provides computerized equipment to control tools that tighten threaded
fasteners on cars, trucks, locomotives and heavy equipment to provide high
quality threading applications. General Motors is the primary customer for the
Company's fastening systems products. The fastening systems business was fully
integrated into Hickok's operations by June, 1994.

         In January, 1996 the Company added new products and customers within
the instrumentation area with the acquisition of the Beacon Gage Division of
Maradyne Corporation. Beacon Gage manufactures specialty pressure gauges for
railroads and transit cars. The gauge business was fully integrated into
Hickok's operations by May, 1996.

         In February, 1998 the Company added new products and customers within
the automotive aftermarket with the acquisition of Waekon Industries, a
privately owned company in Kirkwood, Pennsylvania. Waekon manufacturers a
variety of testing equipment used by automotive technicians. The Waekon name has
become the trademark used by the Company to market its products to the
automotive aftermarket.

         The Company's operations are currently concentrated in the United
States. Sales are primarily to domestic customers although the Company also
makes sales to international customers on a world-wide basis. The Company
established international representation in the sales and service area during
fiscal 1995.

            Revenue by class of product is shown in the table below.

Operating Segment Information
-----------------------------

         The Company's operations are combined into two reportable business
segments: indicators and gauges and automotive diagnostic tools and equipment.
Reference is made to "Segment and Related Information" on pages 16 and 17 of
the Independent Auditors' Report, which is incorporated herein by reference,
for financial information relating to operating segments.


                                       3
<PAGE>   4

     Indicators and Gauges
     ---------------------

         For over fifty years the Company has specialized in developing and
manufacturing precision indicating instruments used in aircraft, locomotives and
other applications. Within the aircraft market, instruments are sold primarily
to manufacturers of business and pleasure aircraft. Within the locomotive
market, indicators are sold to both original equipment manufacturers and to
operators of railroad equipment. The Company added pressure gauges to its
offerings to locomotive customers in 1996. Indicators and gauges represented
approximately 14% of the Company's sales for fiscal 1999.

         New product development in fiscal 1999 revolved around the decision to
use internal resources to certify the DIGILOG series of instruments with the
FAA. This instrument line is a combination analog/digital indicator for the
aircraft market which, based on initial customer response, has the potential to
provide a 20% sales increase in the indicator business segment in fiscal 2000.
Cost of certification is anticipated to be under $50,000.

     Automotive Diagnostic Tools and Equipment
     -----------------------------------------

         In the late 1980's the Company began designing and marketing
instruments used to diagnose problems and to support the servicing of automotive
electronic systems. These products were initially sold to Ford Motor Company but
are now sold direct to Ford dealerships and to the aftermarket using jobbers,
wholesalers and wagon distributors. The Company increased its aftermarket
business with the acquisition in February, 1998 of Waekon Industries which
manufactures a variety of testing equipment used by automotive technicians. The
acquisition added new distribution sources and significant new products for the
aftermarket. The aftermarket currently accounts for approximately 29% of
automotive diagnostic and specialty tool sales as compared with 19% in fiscal
1998. As a whole, automotive diagnostic tools and equipment represented
approximately 86% of the Company's sales for fiscal 1999.

         The fastening control system is another automotive product sold by the
Company. The product resulted from the acquisition of the fastening systems
business from Allen-Bradley in February, 1994. Fastening instrumentation is used
to monitor and control pneumatic and electric tools that tighten threaded
fasteners so as to provide high quality threading applications. The equipment,
especially large networked systems, has been historically sold primarily to
General Motors. With the introduction of new products such as the pulse tool
control and Windows based user station software the Company is attempting to
expand its customer base to include tool manufacturers and other car, truck and
farm equipment manufacturers. A market research study is currently in process to
determine the viability of this strategy.

         Until the end of fiscal 1997 the Company also developed software and
designed systems that were used to develop diagnostic strategies including
engine, body chassis and electrical systems in Ford vehicles. This software
development contract was not renewed at the end of fiscal 1997 because Ford
consolidated suppliers in this area. The Company has elected not to pursue
similar activities in the future.

                                       4
<PAGE>   5

         The automotive diagnostic equipment business segment requires a steady
flow of new products in order for the segment to grow and prosper. This could
consist of entirely new products, upgrading existing products, or simply changes
in packaging or design of existing products. During fiscal 1999 the following
major products were either in development or were introduced to the market. The
Fuel System Analyzer, first introduced in late fiscal 1998, was actively
promoted and marketed. The product is used to diagnose fuel delivery problems.
The Gas Cap Tester was also introduced and actively promoted. The product
provides a rapid and precise method for checking the leak rate of gas caps for
inspection or maintenance purposes and is used in numerous state testing
facilities as part of the emissions testing of automobiles. Development of the
Gas Tank Tester began during the fiscal year. This product checks the leak rate
on automobile gas tanks and is anticipated to be ready for market by mid fiscal
2000. It will also be used in state facilities as part of the emissions testing
process.

         Development of the Wheel Speed Sensor began in fiscal 1999 and was
essentially complete by the end of the year. This electronic diagnostic unit is
used to test a vehicle's ABS braking system and will be available late in the
first quarter of fiscal 2000. Ongoing diagnostic maintenance and software
development for the NGS Tester were taken over by the Company in late fiscal
1999. Until this time these functions were performed by Ford for whom the units
were initially built. The NGS Tester is now sold direct to Ford dealerships and
to other aftermarket customers using the Company's various sales channels. This
has extended the viability of the NGS unit for five years or more.

         During fiscal 1999 several fastening system products were in final
development or were newly introduced into the market. Development of the pulse
tool control is in its final stages and the product is expected to be introduced
in early fiscal 2000. Extensive testing delayed introduction approximately six
months. The pulse tool control is an exciting product as it represents a
technological advancement in controlling and calibrating a pulse nut running
tool. A pulse tool is ergonomically more user friendly than other nut running
tools because it eliminates torque reaction. Another new fastening product is
the Windows based user station software introduced late in fiscal 1999. A
$500,000 initial order was received with shipment expected in the first quarter
of fiscal 2000. This product has been well received since it is easier to use
and requires less training than its DOS based predecessor. It can also be used
with tool controls other than Hickok's.

     Sources and Availability of Raw Materials
     -----------------------------------------

         Raw materials essential to the business are acquired primarily from a
large number of U. S. manufacturers. Materials acquired from the electronic
components industry include transistors, integrated circuits, resistors,
capacitors, switches, potentiometers and fabricated metal or plastic parts. In
general, the required materials are available, if ordered with sufficient lead
times, from multiple sources at current prices.


                                       5
<PAGE>   6


     Importance of Patents, Licenses, Franchises, Trademarks and Concessions
     -----------------------------------------------------------------------

         The Company presently has several patents and patent applications which
relate to certain of its products. It does not consider that any one patent or
group of patents is material to the conduct of its business as a whole and
believes that its position in the industry is dependent upon its present level
of engineering skill, research, production techniques and service rather than
upon its ownership of patents. Other than the name "Hickok" and "Waekon", the
Company does not have any material licenses, trademarks, franchises or
concessions.

     Seasonality
     -----------

         The Company does not believe there is any significant seasonality
affecting its business, except to the extent that shipments of certain products
are dependent upon customer release dates. Operating results can fluctuate
widely from quarter to quarter as orders for products within the automotive
equipment segment can be large and subject to customer release. There were no
such orders in either of the past two fiscal years.

     Practices Relative to Working Capital Items
     -------------------------------------------

         The nature of the Company's business requires it to maintain sufficient
levels of inventory to meet rapid delivery requirements of customers. The
Company provides its customers with payment terms prevalent in the industry.

     Dependence Upon Single or Few Customers
     ---------------------------------------

         During the fiscal year ended September 30, 1999, sales to Ford and
General Motors Corporation accounted for approximately 32% and 13% respectively
of the consolidated sales of the Company. This compares with 45% and 12%
respectively during the prior fiscal year. The Company has no long-term
contractual relationships with either Ford or General Motors, and the loss of
business from either one without a corresponding increase in business from new
or existing customers would have a material adverse effect on the Company.

     Backlog
     -------

         At September 30, 1999, the unshipped customer order backlog totaled
$3,652,000 in contrast to $2,493,000 at September 30, 1998 and $2,924,000 at
September 30, 1997. The increase in fiscal 1999 is due entirely to an increase
in orders for automotive diagnostic equipment and components. All of the
increase is expected to be shipped in early fiscal 2000. The decrease in fiscal
1998 is due to the following two factors. First, there was a $130,000 reduction
due to lower orders during fiscal 1998 for fastening systems products. Second,
because of the Company's initiative to improve its on-time delivery, there was
an increase in the fill rate on orders for both automotive diagnostic products
and indicating instruments. This increase in the fill rate resulted in a
$475,000 reduction in backlog for these two product classes.

<PAGE>   7

     Government Contract Renegotiation
     ---------------------------------

         No major portion of the business is open to renegotiation of profits or
termination of contracts or subcontracts at the election of the Government. The
amount of revenue derived from Government contracts is currently minimal and not
material.

     Competitive Conditions
     ----------------------

         The Company is engaged in a highly competitive industry and faces
competition from domestic and international firms. Several of the Company's
competitors have greater financial resources and larger sales organizations than
the Company. Competition with respect to the Company's diagnostic tool business
arises from the existence of a number of other significant manufacturers in the
field, such as SPX Corporation, Hewlett-Packard, GenRad and Vetronix which
dominate the total available market in terms of total sales. With regard to
fastening systems products, competition comes from both companies that make the
equipment to control fastening tools and from tool makers themselves. Specific
companies include Beta Tech, Atlas Copco, and Stanley. Hickok is a major
supplier in the high end market consisting of multi-spindle fastening system
control systems. The instrumentation industry is composed primarily of companies
which specialize in the production of particular items as compared to a full
line of instruments. The Company believes that its competitive position in this
field is in the area of smaller, specialized products, an area in which the
Company has operated since 1915 and in which the Company has established itself
competitively by offering high-quality, high-performance products in comparison
to high-volume, mass-produced items.

     Research and Development Activities
     -----------------------------------

         The Company expensed as incurred product development costs of
$2,805,592 in fiscal 1999, $3,028,011 in 1998, and $3,263,857 in 1997. These
expenditures included engineering product support and development of manuals for
both of the Company's business segments.

     Compliance with Environmental Provisions
     ----------------------------------------

         The Company's capital expenditures, earnings and competitive position
are not materially affected by compliance with federal, state and local
environmental provisions which have been enacted or adopted to regulate the
distribution of materials into the environment.

     Number of Persons Employed
     --------------------------

         Total employment by the Company at September 30, 1999 was 259
employees. None of the employees are represented by a union. The Company
considers its relations with its employees to be good.

     Financial Information Concerning Foreign and Domestic Operations and Export
     ---------------------------------------------------------------------------
Sales
-----

         During the fiscal year ended September 30, 1999, all manufacturing,
research and development and administrative operations were conducted in the
United States. Revenues derived from export sales approximated $871,000 in 1999,
$627,000 in 1998, and $616,000 in 1997. Shipments to Canada make up the majority
of export sales.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Introduction
------------

         Until the mid 1980's Hickok was known primarily for its ability to
develop and manufacture high technology, precision indicating instruments for
business and pleasure aircraft, locomotive and general industrial applications.
This reputation was enhanced because of the Company's capabilities in the design
and implementation of electronics circuitry. In recent years the Company has
applied this expertise toward the development of electronic diagnostic equipment
used in the automotive industry. The Company's first major diagnostic tool was
introduced in the early 1990's and sold direct to Ford Motor Company. That tool,
and all the other diagnostic tools sold by the Company, are now distributed
through various aftermarket channels. The Company currently generates
approximately 29% of its revenue from designing and manufacturing diagnostic
tools for the automotive aftermarket. These tools enable automotive service
technicians to identify problems in the rapidly increasing number of electronics
systems in automobiles.

         Until the end of fiscal 1997 the Company also generated about 15% of
its revenue from developing diagnostic strategies and assisting in supporting
the overall diagnostic system for Ford Motor Company. At the end of fiscal 1997
the Company was no longer providing this service since its contract was not
renewed because Ford consolidated suppliers in this area. The Company has
elected not to pursue similar activities in the future.

         Approximately six years ago the Company initiated a strategy to use
existing expertise to diversify its customer base and add new products within
its various product classes. The strategy has been implemented primarily through
acquisitions.

         In February, 1994 the Company added a new product for the automotive
market by acquiring the fastening systems business from Allen-Bradley Company,
Inc. The new business produces computerized equipment to control tools that
tighten threaded fasteners in an automotive assembly plant to provide high
quality threading applications. The acquisition cost $730,675 and was recorded
as an asset purchase. The fastening systems business was fully integrated into
the Company's operations by June, 1994.

         In January, 1996 the Company added revenue to its indicator and gauge
business with the acquisition of the Beacon Gage Division of Maradyne
Corporation. The acquisition cost $647,103 and was recorded as an asset
purchase. Beacon Gage manufactures specialty pressure gauges for railroads and
transit cars. The purchase added new products and customers within the Company's
instrumentation market. Sales of gauge products accounted for approximately 18%
of instrument revenue in fiscal 1999. The gauge business was fully integrated
into the Company's operations by May, 1996.



                                       12
<PAGE>   13

         In February, 1998 the Company significantly increased its automotive
aftermarket business with the acquisition of Waekon Industries, a privately
owned company in Kirkwood, Pennsylvania. Sales of aftermarket products now
account for 29% of automotive diagnostic and specialty tool sales, up from 19%
in fiscal 1998. Waekon manufactures a variety of automotive diagnostic equipment
and specialty tools used by automotive technicians. The acquisition cost
$2,221,302 and was recorded as an asset purchase. Because of its positive
position in the industry, the Waekon name has become the trademark used by the
Company to market its products to the automotive aftermarket.

         The timing of order releases in the Company's automotive diagnostic
equipment business can cause wide fluctuations in the Company's operating
results, particularly on a quarter-to-quarter basis. Orders for such equipment
could be large and subject to customer release. The result can be substantial
variations in quarterly sales and earnings. There were no large orders of this
nature in either of the past two fiscal years. The primary reason for this was
the Company's efforts in recent years to diversify its customer base. However,
in future years the introduction of new products could result in a significant
increase in order levels which may result in substantial variations in quarterly
sales and earnings. The Company is not aware of any seasonal factors which could
cause a similar variation in quarterly operating results.

         Short-term earnings also can be affected by levels of expenditures for
product development. Introduction of new automotive diagnostic products to the
aftermarket on a regular basis is very important for the ongoing success of this
business segment. Consequently, expenditures for product development have been
and will continue to be significant to the Company's operations.

         The Company's order backlog as of September 30, 1999 totaled $
3,652,000 as compared to $2,493,000 as of September 30, 1998 and $2,924,000 as
of September 30, 1997. The increase in fiscal 1999 is due entirely to an
increase in orders for automotive diagnostic equipment and components. All of
the increase is expected to be shipped in early fiscal 2000. The decrease in
fiscal 1998 was due to the following two factors. First, there was a $130,000
reduction due to lower orders during fiscal 1998 for fastening systems products.
Second, because of the Company's initiative to improve its on-time delivery,
there was an increase in the fill rate on orders for both automotive diagnostic
products and indicating instruments. This increase in the fill rate resulted in
a $475,000 reduction in backlog for these two product classes

Reportable Segment Information
------------------------------

         The Company adopted effective September 30, 1999 Financial Accounting
Standards No. 131, Disclosures about Segments of an Enterprise and Related
Information. The Standard requires segment information disclosures based on how
management evaluates operating performance and resource allocations.

         The Company has determined that it has two reportable segments: 1)
indicators and gauges and 2) automotive related diagnostic tools and equipment.
Indicators and Gauges



                                       13
<PAGE>   14

         This segment consists of products manufactured and sold primarily to
companies in the aircraft and locomotive industry. Within the aircraft market,
the primary customers are those companies that manufacture business and pleasure
aircraft. Within the locomotive market, indictors and gauges are sold to both
original equipment manufacturers and to operators of railroad equipment.

         Automotive Diagnostic Tools and Equipment
         -----------------------------------------

         This segment consists primarily of products designed and manufactured
to support the servicing of automotive electronic systems. These products are
sold both direct and through the aftermarket using a variety of distribution
methods. The acquisition of Waekon Industries in 1998 added significant new
products and distribution sources for the aftermarket.

         Included in this segment are fastening control products used primarily
by a large automobile manufacturer to monitor and control the nut running
process in an assembly plant. This equipment provides high quality threading
applications. The product was added in fiscal 1994 when the Company acquired the
fastening systems business from Allen-Bradley Company.

Results of Operations
---------------------

         Sales for the fiscal year ended September 30, 1999 declined to
$18,826,827, a decrease of approximately 9% from fiscal 1998 sales. This
decrease in sales was primarily volume-driven and attributable entirely to lower
product sales of approximately $2,161,000, or 11%, offset by a $220,000 or 19%
increase in service revenue. Service revenue was up due to an increase in
billable repairs on automotive products. The current level of service sales is
expected to continue in fiscal 2000. The reduction in product sales occurred in
the first six months of the fiscal year primarily in the automotive diagnostic
and fastening systems product classes. Product sales of these two product
classes in the last six months of the year were up approximately 3% over the
prior year. Sales of automotive diagnostic products in fiscal 1999 dropped by
$707,000 or 7% due to a $2,031,000 or 20% reduction in OEM sales offset by a
$1,324,000 or 49% increase in automotive product sales to the aftermarket. Sales
of fastening systems products dropped by $899,000 or 32% due to a continued
reduction in orders from General Motors for large networked systems. The company
anticipates that overall product sales will increase approximately 20% in fiscal
2000 primarily due to an increase in sales of automotive aftermarket products
based on higher orders already booked and the market's positive reception to
existing product offerings.

         Sales for the fiscal year ended September 30, 1998 declined slightly to
$20,768,362, a decrease of approximately 2% from fiscal 1997 sales. This
decrease in sales was attributable to a $2,782,460 decrease in service revenue
offset by a $2,391,724 increase in product sales. In the service category the
reduction was due to the absence of diagnostic service revenue caused by the
termination of a contract in late fiscal 1997 to provide such services to Ford
Motor Company. The contract was not renewed because Ford consolidated suppliers
in this business segment. The


                                       14
<PAGE>   15

increase in product sales was primarily volume driven and due to a $2,834,000
increase in automotive diagnostic sales of which $1,941,645 represented sales of
aftermarket automotive products manufactured by Waekon which was acquired on
February 17, 1998. The increase in product sales is also attributed to a
$517,000 increase in sales of indicating instruments. Offsetting the above
mentioned increases was a $917,000 decrease in sales of fastening system
products due to continued lower orders from General Motors for large networked
systems.

         Cost of products sold in fiscal 1999 was $10,606,454 or 60.9% of net
product sales. In fiscal 1998 cost of products sold was $10,678,809 or 54.5% of
net product sales. Cost of products sold during fiscal 1997 was $9,874,129 or
57.4% of net product sales. The increase in the percentage of cost of products
sold applicable to product sales between fiscal 1999 and fiscal 1998 was due
primarily to a change in product mix as sales of lower margin automotive
diagnostic products to the aftermarket and other markets continued to represent
a larger proportion of total product sales. The cost of products sold percentage
should decrease slightly in fiscal 2000 due to a change in product mix and
improved plant utilization. The decrease in the percentage of cost of products
sold relative to product sales between fiscal 1998 and fiscal 1997 was due
primarily to product mix and, to a lesser extent, to cost containment.

         Cost of services sold in fiscal 1999 was $935,231 or 66.7% of net
service sales. Cost of services sold during fiscal 1998 was $885,731 or 74.9% of
net service sales. Cost of services sold during fiscal 1997 was $3,528,069 or
89.0% of net service sales. The reduction in the cost of services sold
percentage between fiscal 1999 and fiscal 1998 was due to volume related
operating efficiencies. The decrease in the cost of services sold as a
percentage of net service sales between fiscal 1998 and fiscal 1997 is primarily
due to the elimination of costs associated with the termination of a contract in
late fiscal 1997 to provide diagnostic services to Ford Motor Company. The
percentage of cost of services sold relative to net service sales is expected to
remain unchanged in fiscal 2000.

         Product development expenditures in fiscal 1999 were $2,805,592 which
was 7% lower than expenditures of $3,028,211 in fiscal 1998. This decrease was
due to reduction in engineering and development expenditures on products
completed or nearing completion in fiscal 1999 such as the Gas Cap and Gas Tank
Testers and the pulse tool control. Product development expenditures in fiscal
1998 were $3,028,211 which was 7% lower than fiscal 1997 expenditures of
$3,263,857. This decrease was due to a reduction in engineering and development
expenditures on products completed or nearing completion in fiscal 1998.
Products in this category include the Fuel System Analyzer, the Pro-Spec 1000,
and the Watchdog 1000. It is anticipated that the amount spent on product
development in fiscal 2000 will be slightly higher than the amount spent in
fiscal 1999 based on the ongoing need to develop a steady flow of new diagnostic
products for the automotive aftermarket.

         Marketing and administrative expenses amounted to $5,106,577 which was
27.1% of net sales in fiscal 1999; $4,824,995, or 23.2% of net sales in fiscal
1998; and $3,691,892, or 17.4% of net sales in fiscal 1997. Expenditures in
fiscal 1999 were 6% higher than fiscal 1998 due to the inclusion of Waekon for a
full twelve months. Waekon was acquired by Hickok in


                                       15
<PAGE>   16

February, 1998. Expenditures in fiscal 1998 were 31% higher than the amount
spent in fiscal 1997. Approximately 71% of the dollar increase, or $800,091
represented marketing and administrative expenses incurred by Waekon which
Hickok acquired in fiscal 1998. The balance of the increase represented higher
administrative expenses including an increase in the bonus applicable to fiscal
1998 operations and expenses associated with upgrading the Company's computer
systems. The Company anticipates that marketing and administrative expenses will
increase approximately 10% in fiscal 2000 due to the expected increase in
automotive aftermarket sales.

         Interest charges were $68,171 in fiscal 1999 compared with $58,908 in
fiscal 1998 and $10,966 in fiscal 1997. The increase in interest charges in
fiscal 1999 compared to fiscal 1998 was due to the inclusion of long-term debt
associated with the Waekon acquisition on February 17, 1998 for all of fiscal
1999. The increase in interest charges in fiscal 1998 compared to fiscal 1997
was due to the additional long term debt incurred with the Waekon acquisition in
February, 1998.

         Other income in fiscal 1999 of $51,527 consists primarily of interest
income on short-term investments and discounts on purchases. Other income in
fiscal 1998 and fiscal 1997 of $145,692 and $70,132, respectively, also
consisted of interest income on short-term investments and discounts on
purchases.

         Income taxes in fiscal 1999 were a negative $375,500 which represents a
recovery of income taxes at a 58.3% effective tax rate. The recovery rate in
fiscal 1999 exceeded the normal tax rate of 37% due to the recognition of both
current and prior year research and development tax credits in an amount greater
than what was previously estimated. Income taxes in fiscal 1998 were $403,000
which represents a 28.0% effective tax rate. Fiscal 1997 income taxes were
$255,000 which represents an effective tax rate of 29.7%. The effective tax rate
in both fiscal 1998 and fiscal 1997 were below the normal rate also due to the
recognition of research and development tax credits in an amount greater than
what was estimated at the end of the prior year. It is anticipated that the
effective tax rate in fiscal 2000 will approach the rates experienced in fiscal
1998 and fiscal 1997 due to the anticipated existence of research and
development tax credits.

         The net loss in fiscal 1999 was $268,171, or $.22 per share which was a
decrease of $1,302,571 or 126% from fiscal 1998 net income of $1,034,400. Net
income in fiscal 1998 was $1,034,400, or $ .86 per share, which was an increase
of $429,083, or 70.9% from fiscal 1997 net income of $ 605,317. The change in
fiscal 1999 versus fiscal 1998 was due primarily to a decrease in automotive
diagnostic sales to the OEM market and a decrease in fastening systems sales of
large networked systems. These reduced sales occurred in the first six months of
the fiscal year. In addition, there was a reduction in gross product margin due
to a change in product mix as sales of lower margin automotive diagnostic
products to the aftermarket and non OEM markets represented a larger proportion
of total product sales. The increase in net income in fiscal 1998 versus fiscal
1997 was primarily due to an improvement in gross margin on product sales
coupled with a 14% increase in product sales.

Liquidity and Capital Resources
-------------------------------

         Current assets of $10,186,061 at September 30, 1999 were 5.9 times
current liabilities and the total of cash and receivables was 2.3 times current
liabilities. These ratios compare to 5.9 and 2.4 respectively at the end of
fiscal 1998. Total current assets were down approximately $414,000 from the
previous year end due to a reduction in cash and cash equivalents of
approximately $1,059,000 which was used to fund a $679,000 increase in accounts
receivable and a $165,000 decrease in payroll and related expenses.

         Working capital at September 30, 1999 was $8,473,150 as compared to
$8,818,135 a year ago. The decrease was due to the use of cash and cash
equivalents to fund a reduction in accrued expenses.

         During the fiscal year the Company's business may require relatively
large inventories of both work-in-process and finished goods in order to meet
anticipated delivery schedules. During fiscal 1999 there was no need to build
inventory since sales for the year were down from the previous year.
Nevertheless, whenever there may be a requirement to increase inventory in
fiscal 2000 there will be a negative but temporary impact on liquidity. The
Company believes that internally generated funds and a $5,000,000 revolving line
of credit will provide sufficient liquidity to meet ongoing working capital
requirements.

         Internally generated funds in fiscal 1999 were a negative $370,925 and
were not adequate to fund the Company's primary non-operating cash requirements
consisting of capital expenditures and long-term debt payments of $460,954 and
$160,693 respectively. The primary reason for the negative cash flow from
operations was a $679,279 increase in accounts receivable. In fiscal 1998
internally generated funds were a positive $1,867,048 and were more than
adequate to fund the Company's primary non-operating cash requirements
consisting of capital expenditures of $390,290 and long-term debt payments of
$65,306. In fiscal 1997 internally generated funds were a positive $4,216,015
and were more than adequate to fund the Company's primary non-operating cash
requirement consisting of capital expenditures which amounted to $366,842. The
primary reason for the positive cash flow in fiscal 1997 was a $2,068,580
decrease in accounts receivable. The Company anticipates a slight increase in
accounts receivable in fiscal 2000 due to higher sales. Nevertheless, the
Company expects internally generated funds in fiscal 2000 from operating
activities, primarily net income, to be adequate to fund approximately $600,000
of capital expenditures in addition to $133,000 due on the current portion of
long-term debt. Most of the capital expenditures will be made to upgrade
engineering and manufacturing equipment.

         In February, 1999 the Company amended an existing credit agreement with
its financial lender. The agreement expires in February, 2000 and provides for
an unsecured revolving credit facility of $5,000,000 with interest at the prime
commercial rate with a LIBOR option and is unsecured. At September 30, 1999, the
Company had $100,000 outstanding under this loan facility and remains in
compliance with its loan covenants. The revolving credit facility is subject to
annual review by the Company's lender. Although no determination has been made
to seek


                                       17
<PAGE>   18

renewal of the credit agreement, the Company believes that, given its current
financial condition, renewal at the existing amount may be obtained on
acceptable terms.

Impact of Inflation
-------------------

         In recent years, inflation has had a minimal effect on the Company
because of low rates of inflation and the Company's policy prohibiting the
acceptance of long-term fixed rate contracts without provisions permitting
adjustment for inflation.

Year 2000 Readiness Disclosure
------------------------------

         In late fiscal 1997 the Company began its review of Year 2000 issues
with emphasis placed on information technology systems software and hardware.
During fiscal 1998 the Company expanded its review to include non-information
technology systems and the readiness of key third parties, primarily suppliers
and customers. The Company used internal resources to make its assessment.

         The Company determined that its primary information systems software
and hardware were not Year 2000 compliant and decided to replace non-compliant
equipment and software. Training and testing occurred throughout all of fiscal
1998. Installation began in early fiscal 1999 and has been completed. The system
is functioning properly.

         The Company's review of non-information technology systems and the
readiness of key third parties is complete. Based on assessment efforts to date,
the Company does not believe that the Year 2000 issue applicable to these two
areas will have a material adverse effect on the Company's business and
operating results. This assessment is based on certain assumptions and
expectations, primarily the ability of third parties to remediate their own Year
2000 issues. Unexpected and significant compliance problems in this area,
including the failure of key third parties such as suppliers, customers, public
utilities and government to complete their year 2000 effort, could result in a
material adverse effect on the Company's business and operating results. The
Company's most likely worst case scenario would be a short-term slowdown or
cessation of manufacturing operations at one or more of its facilities and a
short-term inability on the part of the Company to process orders and to deliver
product to customers in a timely manner. Though the Company does not expect a
material adverse impact on operations, contingency plans are completed. Such
plans primarily involve the use of alternative suppliers and transportation
vendors.

         Costs associated with the Company's assessment and remediation of Year
2000 issues were not material in fiscal 1999. The Company has used cash and cash
equivalents to fund such costs.

Forward-Looking Statements
--------------------------

         The foregoing discussion includes forward-looking statements relating
to the business of the Company. These forward-looking statements, or other
statements made by the Company, are made based on management's expectations and
beliefs concerning future events impacting the Company and are subject to
uncertainties and factors (including, but not limited to, those specified below)
which are difficult to predict and, in many instances, are beyond the control of
the Company. As a result, actual results of the Company could differ materially
from those expressed in or implied by any such forward-looking statements. These
uncertainties and factors include (a) the Company's dependence upon a limited
number of customers, (b) the Company's reliance on large orders to generate
product sales, (c) the Company's ability to make the transition from serving
primarily OEM customers to serving smaller and more diffuse customers in the
automotive aftermarket, (d) the highly competitive industry in which the company
operates, which includes several competitors with greater financial resources
and larger sales organizations, (e) the acceptance in the marketplace of new
products and/or services developed or under development by the Company including
automotive diagnostic products, fastening systems products and indicating
instrument products, and (f) the ability of significant third parties with whom
the Company does business to provide products and services in the Year 2000 and
beyond.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
-------------------------------------------------------------------

         The Company is exposed to certain market risks from transactions that
are entered into during the normal course of business. The Company has not
entered into derivative financial instruments for trading purposes. The
Company's primary market risk exposure relates to interest rate risk. The
Company's only debt subject to interest rate risk is its revolving credit
facility. The Company has a balance of $100,000 on its revolving credit facility
at September 30, 1999, which is subject to variable rate of interest based on
the prime commercial rate with a LIBOR option. Assuming borrowings at September
30, 1999, a one-hundred basis point change in interest rates would affect the
Company's pre-tax earnings by approximately $1,000 annualized. As a result, the
Company believes that the market risk relating to interest rate movements is
minimal.

1. NATURE OF OPERATIONS
Hickok Incorporated and its wholly-owned domestic subsidiaries (Company)
develop and manufacture products used by companies in the transportation
industry. Among the products are indicators and gauges sold to companies in
aircraft and locomotive markets. On a much larger scale, the Company
manufactures diagnostic equipment used by automotive technicians to test the
various electronic systems in automobiles. Also within the automotive segment,
the Company manufactures equipment to control the nut running process in an
assembly plant. Prior to 1998, the Company also provided diagnostic services to
a major customer. This contract expired at the end of 1997 and management
elected not to pursue similar activities in the future. The Company serves the
automotive, locomotive and general aviation markets predominately in North
America. Sales in the Company's principal product classes, as a percent of
consolidated sales, are as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
PRINCIPLES OF CONSOLIDATION:
The consolidated financial statements include the accounts of Hickok
Incorporated and its wholly-owned domestic subsidiaries since date of
acquisition. Significant intercompany transactions and balances have been
eliminated in the financial statements.

CONCENTRATION OF CREDIT RISK:
The Company sells its products and services primarily to customers in the United
States and to a lesser extent overseas. The Company extends normal credit terms
to its customers. Customers in the automotive industry (primarily original
equipment manufacturers) comprise 86% of outstanding receivables at September
30, 1999 (84% in 1998). Sales to two customers, each of which were in excess of
10% of total sales, approximated $6,100,000 and $2,400,000 (1999), $9,400,000
and $2,500,000 (1998), $12,700,000 and $2,800,000 (1999). The Company
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of specific customers, historical trends and other information.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS:
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that may affect the reported amounts of certain assets and liabilities and
disclosure of contingencies 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.

REVENUE RECOGNITION:
The Company records sales as manufactured items are shipped to customers.
Revenue from development contracts is recognized as earned under terms of the
contracts. The Company warrants certain products against defects for periods
ranging primarily from 12 to 36 months. Charges against income for warranty
expense and sales returns and allowances were immaterial during each of the
three years in the period ending September 30, 1999.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


      The Company applies APB Opinion No. 25, "Accounting for Stock Issued To
Employees" and related interpretations in accounting for its stock plans as
allowed under FAS Statement No. 123, "Accounting for Stock-Based Compensation."
Accordingly, the adoption of this statement did not affect the Company's results
of operations, financial position or liquidity. Had compensation cost for fixed
price stock options granted in 1999, 1998 and 1997 been determined consistent
with FAS 123, pro forma net income and earnings per share would have been as
follows:

The fair value method of accounting has not been determined for options granted
prior to October 1, 1995. The effects of applying FAS No. 123 in this pro forma
disclosure are not necessarily indicative of future amounts.

The fair value of issued stock options is estimated on the date of grant using
the Black-Scholes option pricing model. The Black-Scholes option pricing model
was originally developed for use in estimating the fair value of traded options
which have different characteristics from the Company's employee stock options.
The model is also sensitive to changes in the subjective assumptions which can
materially affect the fair value estimate. As a result, management believes that
the Black-Scholes model may not necessarily provide a reliable single measure of
the fair value of employee stock options. The following weighted-average
assumptions were used in the option pricing model for 1999, 1998 and 1997
respectively: a risk free interest rate of 6.0%, 5.2% and 5.9%; an expected life
of 5 years; an expected dividend yield of 2.0%, 1.3% and 1.6%; and a volatility
factor of .15, .30 and .20.

9. EMPLOYEE BENEFIT PLANS
The Company has a formula based profit sharing bonus plan for officers and
key employees. The formula takes into account "Economic Profit" in determining
the bonus pool. The bonus distribution is determined by the Compensation
Committee of the Board of Directors after considering such factors as salary,
length of service and merit. The maximum individual distribution is 50% of the
distributee's salary. For fiscal years ended September 30, 1999, 1998 and 1997,
approximately -0-, $73,000, and -0-, respectively, were expensed.

The Company has a 401(k) Savings and Retirement Plan covering all
full-time employees. Company contributions to the plan, including matching of
employee contributions, are at the Company's discretion. For fiscal years ended
September 30, 1999, 1998 and 1997, approximately $38,217, $30,106, and -0-,
respectively, were contributed to the plan. The Company does not provide any
other post retirement benefits to its employees.

The Company has a deferred compensation plan which permits selected
management and highly compensated employees to make tax deferred contributions
in the form of salary reductions instead of, or in addition to, contributions
made by them under the 401(k) Savings and Retirement Plan. For fiscal years
ended September 30, 1999, 1998 and 1997, approximately $22,443, $5,542, and
$9,725 respectively, were allocated by the participants to this plan and is
included in "Accrued Payroll and Related Expenses."

10. ACQUISITIONS
On February 17, 1998, the Company purchased certain assets of Waekon
Industries, Inc. for $2,221,302 which has been accounted for under the purchase
method of accounting. The purchase included accounts receivable ($504,282),
inventory ($719,244), prepaid and other assets ($42,786), machinery and
equipment ($380,100), assumption of current liabilities ($425,895), and goodwill
($1,000,785). The Company also recorded as goodwill closing costs related to the
purchase ($205,216), and the present value of a five year earn out contract
having a minimum required pay out of $585,892. The earn out is payable in equal
annual installments of $150,000 including interest, beginning December 30, 1998.
The earn out is calculated based on a percentage of income before tax and of
revenues for 5 years from date of acquisition. Goodwill is being amortized over
20 years.

Pro forma effects of the Waekon Industries, Inc. purchase on fiscal 1997
operations were reported in Unaudited Consolidated Pro Forma Condensed Financial
Statements included with Form 8-K/A dated February 17, 1998. The following pro
forma data summarizes the results of operations of the Company for the twelve
months ended September 30, 1997 and for the twelve months ended September 30,
1998, assuming Waekon was acquired at the beginning of each period presented. In
preparing the pro forma data, adjustments have been made to conform Waekon's
accounting policies to those of the Company and to reflect purchase accounting
adjustments and interest expense.

The pro forma information does not purport to be indicative of the results
of operations which would have actually been obtained if the acquisition had
occurred on the dates indicated or the results of operations which will be
reported in the future.

11. SEGMENT AND RELATED INFORMATION
The Company has adopted SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, which changes the way the Company reports
the information about its operating segments. The information for 1997 and 1998
has been restated from the prior year's presentation in order to conform to the
current-year presentation.

The Company's four business units have separate management teams and
infrastructures that offer different products and services. The business units
have been aggregated into two reportable segments: 1.) indicators and gauges and
2.) automotive related diagnostic tools and equipment.

INDICATORS AND GAUGES
This segment consists of products manufactured and sold primarily to
companies in the aircraft and locomotive industry. Within the aircraft market,
the primary customers are those companies that manufacture business and pleasure
aircraft. Within the locomotive market, indicators and gauges are sold to both
original equipment manufacturers and to operators of railroad equipment.

AUTOMOTIVE DIAGNOSTIC TOOLS AND EQUIPMENT
This segment consists primarily of products designed and manufactured to

to the aftermarket using a variety of distribution methods. The acquisition of
Waekon Industries in 1998 added significant new products and distribution
sources for the aftermarket.

assembly plant. This equipment provides high quality threading applications. The
product was added in fiscal 1994 when the Company acquired the fastening systems
business from Allen-Bradley Company.
