PART I

ITEM 1. BUSINESS

General

Gencor Industries, Inc. and its subsidiaries (the Company) is a leading manufacturer of heavy machinery used in the production of
highway construction materials, synthetic fuels, and environmental control equipment. The Companys products are manufactured in two facilities in the United States and one facility located in the United Kingdom. The Companys products are
sold through a combination of Company sales representatives and independent dealers and agents located throughout the world.

The Company designs and
manufactures machinery and related equipment used primarily for the production of asphalt and highway construction materials. The Companys principal core products include asphalt plants, combustion systems and fluid heat transfer systems. The
Companys technical and design capabilities, environmentally friendly process technology, and wide range of products have enabled it to become a leading producer of equipment worldwide. The Company believes it has the largest installed base of
asphalt production plants in the United States.

Because the Companys products are sold primarily to the highway construction industry, the business
is seasonal in nature. The majority of orders for the Companys products are received between October and February, with a significant volume of shipments occurring prior to May. The principal factors driving demand for the Companys
products are the level of government funding for domestic highway construction and repair, infrastructure development in emerging economies, the need for spare parts, and a trend towards larger plants resulting from industry consolidation.

In 1968, the foundation of the Company was formed by the merger of Mechtron Corporation with General Combustion, Inc. and Genco Manufacturing, Inc. The
new entity reincorporated in Delaware in 1969 and adopted the name Mechtron International Corporation in 1970. In 1985, the Company began a series of acquisitions into related fields starting with the Beverley Group Ltd. in the United Kingdom.
Hy-Way Heat Company, Inc. and the Bituma Group were acquired in 1986. In 1987, the Company changed its name to Gencor Industries, Inc. and acquired the Davis Line Inc. and its subsidiaries in 1988.

##### Table of Contents

In January 1998, the Company finalized agreements with Carbontronics, LLC (CLLC) pursuant to which the
Company sold, designed, manufactured, and installed four synthetic fuel production plants. These plants were subsequently sold by CLLC to a limited partnership (LP), Carbontronics Synfuels Investors, L.P., which is now the owner of the
plants. The Company was paid in full for these plants in 1998. In addition to payment for the plants, per agreement, the Company received a member interest of 45% in CLLC. Future revenue to CLLC is based upon the production of these plants
continuing to qualify for tax credits under Section 29 of the Internal Revenue Code, and the ability to economically produce and successfully market synthetic fuel produced by the plants. If the LP is successful in producing fuel which
qualifies for tax credits, sells the synthetic fuel, sells the tax credits to investors, and has sufficient cash flow to cover all operating expenses, then the LP remits cash to CLLC as additional purchase price for the sale of the plants. CLLC
generally distributes any cash receipts to its investors.

Also, the Company received a 25% partnership position in the General Partner (GP) of
the LP and in Carbontronics II, LLC (C2LLC). C2LLC receives royalty payments from the LP only if the LP is successful in producing fuel which qualifies for tax credits, sells the synthetic fuel, sells the tax credits to investors, and
has sufficient cash flow to cover all other operating expenses. The remaining interests in the GP, CLLC, and C2LLC are owned by other, unrelated entities. An administrative member of the GP, not the Company, is responsible for administration of the
day-to-day affairs of the GP and LP. The Company is entitled to appoint only one of the three members of the GP Management Committee and has 1/3 of the voting rights thereof. As a part of the member positions in CLLC, C2LLC, and the GP, the Company
has the potential for income subject to the performance of the LP. Future benefits realizable by the Company on the synthetic fuel production plants depend on whether the production from these plants will continue to qualify for tax credits under
Section 29 of the Internal Revenue Code and the ability to economically produce and successfully market synthetic fuel produced by the plants.

On August 8, 2003, the Company was notified by its investee General Partner that the income tax returns for its
synthetic fuel producing partnership were being audited. As previously reported the Limited Partners may declare a Tax Event and suspend further distributions indefinitely. The Company was informed that the Limited Partners had declared
a Tax Event and therefore future distributions had ceased.

On December 12, 2003, the Company was notified by the General Partner that the
IRS had issued rulings dated December 10, 2003 to the producing partnership concluding that, if the partnership adheres to the specified production methods and chemistry, the partnership would be entitled to the section 29 credit for the
production of qualified fuel that is sold to unrelated persons.

Although the IRS advised us that it is satisfied with the chemical testing procedures, it
nevertheless proceeded with a general IRS audit. Therefore the previously imposed Tax Event continued and the Limited Partners were not allowing revenue to be distributed to the Company until satisfactory conclusion of the audit.

On January 5, 2005, the Company was informed that the IRS had concluded its examination of the investees with no material adverse findings. As a result,
distributions suspended since August 2003 resumed. The Company recognized income of $14.5 million in 2006, for the distribution received less an accrual of $1 million for certain expenses associated with efforts by the Company as plaintiff in a
matter against its synthetic fuels partners. The Company received $44.2 million during the fiscal year 2005. The Company received no distributions in fiscal 2004. These distributions are subject to state and Federal income taxes.

Future distributions from these entities depend upon the production of these operations continuing to qualify for tax credits under Section 29 of the Internal
Revenue Code and the ability to economically produce and market synthetic fuel produced by the plants. One of the contingencies related to future benefits from these entities is based on the average price of crude oil. Per a provision of
Section 29, if the average price of crude oil reaches a certain level, the tax credits will terminate. The recent escalation in oil prices raises serious doubt on the continued availability of tax credits under Section 29 for the future.
If oil prices remain at the current levels or increase, the tax credits could phase-out or terminate.

On May 15, 2006, the Company received
notification from the administrative partner of these investments that the limited partners gave notice that the plants should be idled until further notice. They indicated the operations will be curtailed until the earlier of: 1) a
legislative change adjusting the determination of the phase-out price, or 2) a downward movement in oil prices signaling some improved expectation that the credit phase-out will still provide sufficient capital to support the continuation of
operations. On October 6, 2006, the Company received notification that the synthetic fuel plants had resumed operation and on October 18, 2006, the Company received a cash distribution of $3.1 million.

The existing tax credit legislation is scheduled to expire at the end of calendar year 2007.

Any one of the above eventualities may interrupt, reduce, or terminate further distributions.

Products

Asphalt Plants. The Company manufactures and produces hot-mix asphalt plants used in the production of asphalt paving materials. The Company
also manufactures related asphalt plant equipment including hot mix storage silos, fabric filtration systems, cold feed bins and other plant components. The Companys H&B (Hetherington and Berner) product line is the worlds oldest
asphalt plant line, first manufactured in 1894. The Companys subsidiaries, Bituma Corporation, formerly known as Boeing Construction Company, developed the continuous process for asphalt production, which has been adopted as the United States
industrys standard technology, as well as patented the counterflow technology, several adaptations of which have become the industry standard, which recaptures and burns emissions and vapors, resulting in a cleaner and more efficient process.
The Company manufactures a very comprehensive range of fully mobile batch plants, as well as mobile shredders and trommel screens.

##### Table of Contents

Combustion Systems and Industrial Incinerators. The Company manufactures combustion systems, which are large
burners that can transform most solid, liquid or gaseous fuels into usable energy, or burn multiple fuels, alternately or simultaneously. Through its subsidiary General Combustion, the Company has been a significant source of combustion systems for
the asphalt and aggregate drying industries since the 1950s. The Company also manufactures soil decontamination machinery, as well as combustion systems for rotary dryers, kilns, fume and liquid incinerators, boilers and tank heaters. The
Company believes maintenance and fuel costs are lower for its burners because of their superior design.

Fluid Heat Transfer Systems. The
Companys General Combustion subsidiaries in the USA and U.K. manufacture the Hy-Way heat and Beverley lines of thermal fluid heat transfer systems and specialty storage tanks for a wide array of industry uses. Thermal fluid heat transfer
systems are similar to boilers, but use high temperature oil instead of water. Thermal fluid heaters have been replacing steam pressure boilers as the best method of heat transfer for storage, heating and pumping viscous materials (i.e., asphalt,
chemicals, heavy oils, etc.) in many industrial and petrochemical applications worldwide. The Company believes the high efficiency design of its thermal fluid heaters can outperform competitive units in many types of process applications. Heaters
are available for vertical, horizontal and underground tanks in steel, stainless steel, and other materials designed to meet large or small specific job requirements.

Product Engineering and Development

The Company is engaged in product engineering and development efforts to
expand its product lines and to further develop more energy efficient and environmentally compatible systems.

Significant developments include the use of
cost effective, non-fossil fuels, biomass (bagasse, municipal solid waste, sludge and wood waste), refuse-derived fuel, coal and coal mixtures, the economical recycling of old asphalt and new designs of environmentally compatible asphalt plants.
Product engineering and development activities are directed toward more efficient methods of producing asphalt and lower cost fluid heat transfer systems. In addition, efforts are also focused on developing combustion systems that operate at higher
temperatures and offer a higher level of environmental compatibility. The Company continues to evaluate opportunities in the energy field.

Sources
of Supply and Manufacturing

Substantially all products sold by the Company and its subsidiaries are manufactured or assembled by the Company,
except for procured raw materials and hardware. The Company purchases a large quantity of steel, raw materials and hardware used to manufacture its products from hundreds of suppliers and is not dependent on any single supplier. Periodically, the
Company reviews the cost effectiveness of internal manufacturing versus outsourcing its product lines to independent third parties and currently believes it has the internal capability to produce the highest quality product at the lowest cost. This,
however, may change from time to time.

##### Table of Contents

Seasonality

The Company is concentrated in the asphalt-related business and subject to a seasonal slow-down during the third and fourth quarters of the calendar year. Traditionally, the Companys customers do not purchase new equipment for
shipment during the summer and fall months to avoid disrupting their peak season for highway construction and repair work. This slow-down often results in lower reported sales and earnings and/or losses during the first and fourth quarters of the
Companys fiscal year.

Competition

The
markets for the Companys products are highly competitive. Within a given product line, the industry remains fairly concentrated, with typically a small number of companies competing for the majority of a product lines industry sales. The
principal competitive factors include technology and overall product design, dependability and reliability of performance, brand recognition, pricing and after-the-sale customer support. Management believes its ability to compete depends upon its
continual efforts to improve product performance and dependability, competitively price its products, and provide the best customer support and service in the industry.

Sales and Marketing

The Companys products and services have been marketed internationally through a
combination of Company-employed sales representatives and independent dealers and agents.

Sales Backlog

The Companys manufacturing processes allow for a relatively short turnaround from the order date to shipment date of usually less than ninety (90) days.
Therefore, the size of the Companys backlog should not be viewed as an indicator of the Companys annualized revenues or future financial results. The Companys backlog was approximately $28 million and $24 million as of
December 1, 2006 and December 1, 2005, respectively.

Licenses, Patents and Trademarks

The Company holds numerous patents covering technology and applications related to various products, equipment and systems, and numerous trademarks and trade names
registered with the U.S. Patent and Trademark Office and in various foreign countries. In general, the Company depends upon technological capabilities, manufacturing quality control and application know-how, rather than patents or other proprietary
rights in the conduct of its business. The Company believes the expiration of any one of these patents, or a group of related patents, would not have a material adverse effect on the overall operations of the Company.

Government Regulations

The Company believes its design and
manufacturing processes meet all industry and governmental agency standards that may apply to its entire line of products, including all domestic and foreign environmental, structural, electrical and safety codes. The Companys products are
designed and manufactured to comply with Environmental Protection Agency regulations. Certain state and local regulatory authorities have strong environmental impact regulations. While the Company believes that such regulations have helped, rather
than restricted its marketing efforts and sales results, there is no assurance that changes to federal, state, local, or foreign laws and regulations will not have a material adverse effect on the Companys products and earnings in the future.

Environmental Matters

The Company is subject to various federal, state, local and foreign laws and regulations relating to the protection of the environment. The Company believes it is in material compliance with all applicable environmental laws and
regulations. The Company does not expect any material impact on future operating costs as a result of compliance with currently enacted environmental regulations.

The Company has conducted environmental assessments consistent with recognized standards of due diligence on properties and businesses which it acquired. These assessments had not identified contamination resulting from acquired properties
that would be reasonably likely to result in a material adverse effect on the Companys business, results of operations, or financial condition.

Employees

As of September 30, 2006, the Company employed a total of 346 employees; there were 332 employees in the domestic
U.S. operations and 14 employees in the U.K. operations. The Company has collective bargaining agreements covering production and maintenance employees at its Marquette, Iowa facilities. The remaining domestic employees are not represented by a
labor union or collective bargaining agreement. The Company believes that its relationship with its employees is good.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

The following risk factors and other
information included in this Annual Report on Form 10-K should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem
less significant may also impair our business operations. If any of the following risks actually occur, our business operating results and financial condition could be materially adversely affected.

Our business is affected by the cyclical nature of the markets served by us. The demand for our products and service is dependent on general economic conditions
and more specifically, the commercial construction industry. Adverse economic conditions may cause customers to forego or delay new purchases and rely more on repairing existing equipment thus negatively impacting our sales and profits. Rising gas
and oil prices, increasing steel prices, and shortage of qualified workers can have adverse effects on us.

Our business is affected by the level of
government funding for highway construction. In 2005, the Federal Government passed the SAFETEA-LU bill. This bill appropriated a multi-year guaranteed funding for federal highway, transit and safety programs. Many of our customers depend on
funding by Federal and state agencies. Future legislation may increase or decrease government spending.

Income from our investment in synthetic fuel
partnerships is affected by the level of oil prices. The tax credits provided for the synthetic fuel industry under Section 29 of the Internal Revenue Code could phase-out or terminate if oil prices exceed certain levels. Other
contingencies affecting the income from these investments include the ability to economically produce and successfully synthetic fuel produced by these partnerships.

We face risks associated with our international business.We operate manufacturing and sales offices principally located in the United States and the United Kingdom. As a result, we are subject to
business risks inherent in non-U.S. activities, including difficulty in staffing and managing foreign subsidiary operations, difficulty in managing distributors and dealers, adverse tax consequences, political and economic uncertainty and difficulty
in accounts receivable collection. We are subject to the risks associated with the imposition of protective legislation and regulations, including those relating to import or export or otherwise resulting from trade or foreign policy. We cannot
predict whether quotas, duties, taxes or other charges or restrictions will be implemented by the U.S. or any other country upon the import or export of our products. There can be no assurance that any of these factors, or the adoption of
restrictive policies, will not have a material adverse effect on our business, financial condition and results of operations. In addition, we face market risk related to changes in interest rates and



7



---

##### Table of Contents

foreign currency exchange rates. Our principal currency exposure against the U.S. dollar is the British pound. Our
foreign currency exposures generally are not hedged and there can be no assurance that our future results of operations and investments will not be adversely affected by currency fluctuations. Periodically, we use derivative financial instruments
consisting primarily of interest rate hedge agreements to manage exposures to interest rate changes. If we have not adequately managed our exposure to fluctuating interest rates, our earnings and cash flow could be adversely affected.

We may encounter difficulties with future acquisitions. As part of our growth strategy, we intend to evaluate the acquisitions of other companies, assets
or product lines that would complement or expand our existing businesses or broaden our customer relationships. Although we conduct due diligence reviews of potential acquisition candidates, we may not be able to identify all material liabilities or
risks related to potential acquisition candidates. There can be no assurance that we will be able to locate and acquire any business, retain key personnel and customers of an acquired business or integrate any acquired business successfully.
Additionally, there can be no assurance that financing for any acquisition, if necessary, will be available on acceptable terms, if at all, or that we will be able to accomplish our strategic objectives in connection with any acquisition. Although
we periodically consider possible acquisitions, no specific acquisitions are probable as of the date of this Report on Form 10-K.

We could be harmed if
we violate financial covenants contained in our credit facility. Our Revolving Credit and Security Agreement with PNC Bank, N.A., dated August 1, 2003, and amended July 31, 2006, imposes certain financial and operating covenants
upon us, including, among others, restrictions on our ability to incur debt, or take certain other corporate actions. In addition, the credit facility requires that we maintain certain financial ratios and provides for limitations on capital
expenditures. The foregoing covenants may restrict our ability to obtain additional funds, dispose of assets, or otherwise pursue our business strategies, and may impair our ability to obtain additional financing to fund future working capital
requirements, capital expenditures, acquisitions and other general corporate purposes. Changes in economic or business conditions, results of operations or other factors could in the future cause a violation of one or more covenants in the credit
facility.

Demand for our products is cyclical in nature. Orders for our products slow down during the summer and fall months since our
customers generally do not purchase new equipment for shipment in their peak season for highway construction and repair work. In addition, demand for our products depends in part upon the level of capital and maintenance expenditures by the highway
construction industry. The highway construction industry historically has been cyclical in nature and vulnerable to general downturns in the economy. Decreases in industry spending could have a material adverse effect upon demand for our products
and negatively impact our business, financial condition and results of operations.

Our Marketable Securities are comprised of stocks and bonds invested
through a professional investment advisor and are subject to various risks such as interest rates, markets, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the
value of securities, changes in these risk factors could have a material adverse impact on our results of operations.

There are and will continue to be
quarterly fluctuations of our operating results. Our operating results historically have fluctuated from quarter to quarter as a result of a number of factors, including the value, timing and shipment of individual orders and the mix of
products sold. Revenues from certain large contracts are recognized using the percentage of completion method of accounting. We recognize product revenues upon shipment for the rest of our products. Our asphalt production equipment operations are
subject to seasonal fluctuation, which may lower sales and result in possible losses in the first and fourth fiscal quarters of each year. Traditionally, asphalt producers do not purchase new equipment for shipment during the summer and fall months
to avoid disruption of their activities during peak periods of highway construction.

If we are unable to attract and retain key personnel, our business
could be adversely affected. The success of our business will continue to depend substantially upon the efforts, abilities and services of our management team and certain other key employees. The loss of one or more key employees could
adversely affect our operations.

##### Table of Contents

Our ability to attract and retain qualified personnel, either through direct hiring, or acquisition of other businesses
employing such professionals, will also be an important factor in determining our future success.

We may be required to defend our intellectual
property against infringement or against infringement claims of others. We hold numerous patents covering technology and applications related to various products, equipment and systems, and numerous trademarks and trade names registered
with the U.S. Patent and Trademark Office and in various foreign countries. There can be no assurance as to the breadth or degree of protection that existing or future patents or trademarks may afford us, or that any pending patent or trademark
applications will result in issued patents or trademarks, or that our patents, registered trademarks or patent applications, if any, will be upheld if challenged, or that competitors will not develop similar or superior methods or products outside
the protection of any patents issued, licensed or sublicensed to us. Although we believe that none of our patents, technologies, products or trademarks infringe upon the patents, technologies, products or trademarks of others, it is possible that
our existing patent, trademark or other rights may not be valid or that infringement of existing or future patents, trademarks or proprietary rights may occur. In the event that our products are deemed to infringe upon the patent or proprietary
rights of others, we could be required to modify the design of our products, change the name of our products or obtain a license for the use of certain technologies incorporated into our products. There can be no assurance that we would be able to
do any of the foregoing in a timely manner, upon acceptable terms and conditions, or at all, and the failure to do so could have a material adverse effect on us. In addition, there can be no assurance that we will have the financial or other
resources necessary to enforce or defend a patent, registered trademark or other proprietary right, and, if our products are deemed to infringe upon the patents, trademarks or other proprietary rights of others, we could become liable for damages,
which could also have a material adverse effect on us.

We may be subject to substantial liability for the products we produce. We are
engaged in a business that could expose us to possible liability claims for personal injury or property damage due to alleged design or manufacturing defects in our products. We believe that we meet existing professional specification standards
recognized or required in the industries in which we operate, and we have had no material product liability claims brought against us as of the date hereof. Although we currently maintain product liability coverage which we believe is adequate for
the continued operation of our business, such insurance may prove inadequate or become difficult to obtain or unobtainable in the future on terms acceptable to us.

We are subject to extensive environmental laws and regulations, and our costs related to compliance with, or our failure to comply with, existing or future laws and regulations could adversely affect our business and results of
operations. Our operations are subject to federal, state, local and foreign laws and regulations relating to the protection of the environment. Sanctions for noncompliance may include revocation of permits, corrective action orders,
administrative or civil penalties and criminal prosecution. Our business involves environmental management and issues typically associated with historical manufacturing operations. To date, our cost of complying with environmental laws and
regulations has not been material, but the fact that such laws or regulations are changed frequently makes predicting the cost or impact of such laws and regulations on our future operations uncertain.

The loss of one or more of our raw materials supplies could cause production delays, a reduction of revenues or an increase in costs. The principal raw materials
we use are steel and related products. We have no long-term supply agreements with any of our major suppliers. However, we have generally been able to obtain sufficient supplies of raw materials for our operations, and changes in prices of such
materials historically have not had a significant affect on our operations. Although we believe that such raw materials are readily available from alternate sources, an interruption in our supply of steel and related products or a substantial
increase in the price of any of these raw materials could have a material adverse effect on our business, financial condition and results of operations.

We are subject to significant government regulations. We are subject to a variety of governmental regulations relating to the manufacturing of our products. Any failure by us to comply with present or future regulations could
subject us to future liabilities, or the suspension of production that could have a material adverse effect on our results of operations. Such regulations could also restrict our ability to expand our facilities, or could require

##### Table of Contents

us to acquire costly equipment or to incur other expenses to comply with such regulations. Although we believe we have
the design and manufacturing capability to meet all industry or governmental agency standards that may apply to our product lines, including all domestic and foreign environmental, structural, electrical and safety codes, there can be no assurance
that governmental laws and regulations will not become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with a violation. The cost to us of such compliance to date has not materially affected
our business, financial condition or results of operations. There can be no assurance, however, that violations will not occur in the future as a result of human error, equipment failure or other causes. Our customers are also subject to extensive
regulations, including those related to the workplace. We cannot predict the nature, scope or effect of governmental legislation, or regulatory requirements that could be imposed or how existing or future laws or regulations will be administered, or
interpreted. Compliance with more stringent laws or regulations, as well as more vigorous enforcement policies of regulatory agencies, could require substantial expenditures by us and could adversely affect our business, financial condition and
results of operations.

Our management has effective voting control. Our officers and directors beneficially own an aggregate of
approximately 88.2% of the outstanding shares of our $.10 par value Class B stock. The Class B stock is entitled to elect 75% (calculated to the nearest whole number, rounding five-tenths to next highest whole number) of the members of our board of
directors. Further, approval of a majority of the Class B stock is generally required to effect a sale of us and certain other corporate transactions. As a result, these stockholders can elect more than a majority of the board of directors and
exercise significant influence over most matters requiring approval by our stockholders. This concentration of control may also have the effect of delaying or preventing a change in control.

The issuance of preferred stock may impede a change of control or may be dilutive to existing stockholders. Our Certificate of Incorporation, as amended,
authorizes our Board of Director, without stockholder vote, to issue up to 300,000 shares of preferred stock in one or more series and to determine for any series the dividend, liquidation, conversion, voting or other preferences, rights and terms
that are senior, and not available, to the holders of our common stock. Thus, issuances of series of preferred stock could adversely affect the relative voting power, distributions and other rights of the common stock. The issuance of preferred
stock could deter or impede a merger, tender offer or other transaction that some, or a majority, of our common stockholders might believe to be in their best interest or in which our common stockholders might receive a premium for their shares over
the then current market price of such shares.

We may be required to indemnify our directors and executive officers. We have authority under
Section 145 of the Delaware General Corporation Law to indemnify our directors and officers to the extent provided in that statute. Our Certificate of Incorporation, as amended, provides that a director shall not be personally liable to us for
breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the Delaware General Corporation Law. Our Bylaws provide in part that we indemnify each of our directors and
officers against liabilities imposed upon them (including reasonable amounts paid in settlement) and expenses incurred by them in connection with any claim made against them or any action, suit or proceeding to which they may be a party by reason of
their being or having been a director or officer. We maintain officers and directors liability insurance coverage. There can be no assurance that such insurance will be available in the future, or that if available, it will be available
on terms that are acceptable to us. Furthermore, there can be no assurance that the insurance coverage provided will be sufficient to cover the amount of any judgment awarded against an officer or director (either individually or in the aggregate).
Consequently, if such judgment exceeds the coverage under the policy, we may be forced to pay such difference.

We enter into indemnification agreements
with each of our executive officers and directors containing provisions that may require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as officers or directors (other than
liabilities arising from willful misconduct of a culpable nature) and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. Management believes that such indemnification provisions and
agreements are necessary to attract and retain qualified persons as directors and executive officers.

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

Forward-Looking Information

This Form 10-K contains certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act), which represent our expectations and beliefs,
including, but not limited to, statements concerning gross margins, sales of our products and future financing plans, income from investees and litigation. These statements by their nature involve substantial risks and uncertainties, certain of
which are beyond our control. Actual results may differ materially depending on a variety of important factors, including the financial condition of our customers, changes in the economic and competitive environments, whether or not the Company
receives income from its investees, the performance of our investment portfolio and the demand for our products.

For information concerning these factors
and related matters, see Risk Factors in Part I, Item 1A in this Report. However, other factors besides those referenced could adversely affect our results, and you should not consider any such list of factors to be a complete set
of all potential risks or uncertainties. Any forward-looking statements made by us herein speak as of the date of this Report. We do not undertake to update any forward-looking statement, except as required by law.

Results of Operations

Year ended September 30, 2006 compared
with the year ended September 30, 2005

Net sales for the years ended September 30, 2006 and 2005 were $67.1 million and $48.1million,
respectively. Domestic sales during this period for 2006 and 2005 were $63.1 million and $46.9 million, respectively. Domestic sales were higher than the prior year due the improved economy and the passage of the federal highway bill last summer.
Foreign sales increased by $2.7 million due to one large order. Backlog was only $5 million at September 30, 2006, however, it has increased to over $28 million as of December 1, 2006. This compares to a backlog of $24 million as of
December 1, 2005.

Gross margin for fiscal 2006 was $5.8 million higher than fiscal 2005 and as a percent of net sales was 25.0% in 2006 and 22.7% of
sales for 2005. The increased volume in our manufacturing plants improved overhead absorption and improved margins. Domestic margins were negatively affected by $.7 million in 2006 and $.5 million in 2005 due to an increase in the LIFO reserve.

Product engineering and development costs remained at comparable levels with 2005. Selling and administrative expenses increased $1.6 million during 2006
due to higher legal costs and $.5 million due to higher commissions and payroll costs resulting from the higher sales volume.

Operating income was $1.4
million in 2006 compared to a loss of ($1.3 million) in 2005. Operating income increased as a result of increased domestic and foreign business, higher gross margins in 2006, partially offset by the higher selling and administrative expenses.

The increase in value of marketable securities is a result of the net cash invested in marketable securities since the second quarter of fiscal 2005.

The Company recognized income from investees of $14,457 in 2006, for the distribution received less an accrual of $1,000 for certain expenses associated
with our efforts as plaintiff in a matter against its synthetic fuels partners. We received $44,238, during the fiscal year 2005. We received no distributions in fiscal 2004. The operations of Carbontronics LLC consist of the receipt of contingent
payments from the sales of the plants and the distribution thereof to its members. Carbontronics LLC has no other significant operations or assets. The operations of Carbontronics II, LLC consist of the receipt of royalty payments from the plants
and the distribution thereof to its members. Carbontronics II, LLC has no other significant operations or assets. Any income arising from these investments is dependent upon tax credits (adjusted for operating losses at the fuel plants) being
generated as a result of synthetic fuel production, which will be recorded as received.

These distributions are subject to state and Federal income taxes. Future distributions from these entities depend upon
the production of these operations continuing to qualify for tax credits under Section 29 of the Internal Revenue Code and the ability to economically produce and market synthetic fuel produced by the plants. One of the contingencies related to
future benefits from these entities is based on the average price of crude oil. Per a provision of Section 29, if the average price of crude oil reaches a certain level, the tax credits will terminate. The recent escalation in oil prices raises
serious doubt on the continued availability of tax credits under Section 29 for the future. If oil prices remain at the current levels or increase, the tax credits could phase-out or terminate.

Income taxes were 37% of pre-tax income for 2006 and 31% for 2005. The tax provision in 2005 includes a reduction of $2.5 million (5.5%) in the tax contingency
reserve as a result of resolution of prior year tax filings and expiration of the statute of limitations.

Year ended September 30, 2005 compared
with the year ended September 30, 2004

Net sales for the years ended September 30, 2005 and 2004 were $48.1 million and $54.1million,
respectively. Domestic sales during this period for 2005 and 2004 were $46.9 million and $52.7 million, respectively. Domestic sales were lower than the prior year due to the timing of finalizing certain orders and delays in customers receiving
permits. Backlog was only $5 million at September 30, 2005, however has increased to over $24 million as of December 1, 2005. This compares to a backlog of only $13 million as of December 1, 2004.

Gross margin for fiscal 2005 was $5.0 million less than fiscal 2004 and as a percent of net sales were 22.7% in 2005 and 29.4% of sales for 2004. Domestic margins were
negatively affected by $.5 million in 2005 and $.8 million in 2004 due to an increase in the LIFO reserve. Lower sales volume reduced margin by $2 million and unfavorable purchase price variances due to higher steel and other material costs
increased costs by $.8 million.

Product engineering and development costs remained at comparable levels with 2004. Selling and administrative expenses
increased $.5 million during 2005 due to higher legal costs and a bonus paid on the receipt of the cash distributions from our investees. Selling and administrative expenses in 2004 includes $270 of costs related to the tender offer withdrawn in
December 2003.

Operating (loss) was ($1.3) million in 2005. Operating income decreased from $4.2 million and 8% of net sales for 2004, as a result of
reduced domestic business, lower gross margins in 2005, and higher selling and administrative expenses.

Interest expense during 2005 is less than 2004 due
to reduced average borrowings and a lower interest rate. The outstanding bank debt was reduced to zero in the second quarter of fiscal 2005. The increase in value of marketable securities is a result of the net cash invested in marketable securities
since the second quarter of fiscal 2005.

Income from investees consisted of cash distributions of $44,238 in 2005. There were no distributions from
investments in Carbontronics LLC, Carbontronics II LLC, and Carbontronics Fuels LLC, in fiscal 2004. Distributions suspended since August 2003, as a result of an IRS examination, resumed in the second quarter of fiscal 2005. Future distributions
from these entities depend upon the production of these operations continuing to qualify for tax credits under Section 29 of the Internal Revenue Code and the ability to economically produce and market synthetic fuel produced by the plants. One
of the contingencies related to future benefits from these entities is based on the average price of crude oil. Per a provision of Section 29, if the average price of crude oil reaches a certain level, the tax credits will terminate. The
escalation in oil prices in 2005 raises serious doubt on the continued availability of tax credits under Section 29 for the future. If oil prices remain at the recent levels or increase, the tax credits could phase-out or terminate. The
existing tax credit legislation is scheduled to expire at the end of calendar year 2007. Any one of the above eventualities may interrupt, reduce, or terminate future distributions.

Income taxes were 31% of pre-tax income for 2005 and 37% for 2004. The tax provision in 2005 includes a reduction of $2.5
million (5.5%) in the tax contingency reserve as a result of resolution of prior year tax filings and expiration of the statute of limitations.

Liquidity and Capital Resources

We entered into a Revolving Credit and Security Agreement with PNC Bank, N.A. The Agreement established a
three year revolving $20 million credit facility and was renewed through July 31, 2009. The facility provides for advances based on accounts receivable, inventory and real estate. The facility includes a $2 million limit on letters of credit.
At September 30, 2006, we had $.5 million of letters of credit outstanding. The interest rate at September 30, 2006, is at LIBOR plus 2.00% and subject to change based upon the Fixed Charge Coverage Ratio. We are required to maintain a
Fixed Charge Coverage Ratio of 1.1:1. There are no required repayments as long as there are no defaults and there is adequate eligible collateral. Substantially all of our assets are pledged as security under the Agreement. We had no long term debt
outstanding at September 30, 2006 or 2005.

As of September 30, 2006, we had $1.1 million in cash and cash equivalents, and $35.9 million in
marketable securities. The marketable securities are invested in stocks and bonds through a professional investment advisor. The securities may be liquidated at any time into cash and cash equivalents.

Critical Accounting Policies, Estimates and Assumptions

We believe
the following discussion addresses our most critical accounting policies, which are those that are most important to the portrayal of our financial condition and results of operations and require managements most difficult, subjective, or
complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Accounting policies, in addition to the critical accounting policies referenced below, are presented in Note 1 to our
consolidated financial statements, Accounting Policies.

Estimates and Assumptions

In preparing the consolidated financial statements, we use certain estimates and assumptions that may affect reported amounts and disclosures. Estimates and assumptions
are used, among other places, when accounting for certain revenue (e.g. contract accounting), expense, and asset and liability valuations. We believe that the estimates and assumptions made in preparing the consolidated financial statements are
reasonable, but are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate and unanticipated events may occur. We are subject to risks and uncertainties that may cause actual results to differ from estimated results.

Revenues

Revenues from contracts for the design and
manufacture of certain custom equipment are recognized under the percentage-of-completion method. Revenues from all other sales are recorded as the products are shipped or service is performed.

The percentage-of-completion method of accounting for long term contracts recognizes revenue in proportion to actual labor costs incurred as compared with total
estimated labor costs expected to be incurred during the entire contract. All selling, general and administrative expenses are charged to operations as incurred. Provision is made for any anticipated contract losses in the period that the loss
becomes evident.

Investment in Unconsolidated Investees

As of September 30, 2006, 2005, and 2004, we own a 45% interest in Carbontronics LLC and a 25% interest in Carbontronics Fuels LLC and Carbontronics II LLC. These interests were obtained as part of contracts to build four synthetic
fuel production plants during 1998. We have no basis in these equity investments or requirement to provide future funding. Any income arising from these investments is dependent upon tax credits (adjusted for operating losses at the fuel plants)
being generated as a result of synthetic fuel production, which will be recorded as received.

Inflation

The
overall effects of inflation on our business during the periods discussed have not been significant. We monitor the prices we charge for our products and services on an ongoing basis and believe that we will be able to adjust those prices to take
into account future changes in the rate of inflation.

Contractual Obligations

The following table summarizes our outstanding borrowings and long-term contractual obligations at September 30, 2006:

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
MARKET RISK

The Company operates manufacturing facilities and sales offices principally located in the United States and the United Kingdom. The Company is
subject to business risks inherent in non-U.S. activities, including political and economic uncertainty, import and export limitations, and market risk related to changes in interest rates and foreign currency exchange rates. The Companys
principal currency exposure against the U.S. dollar is the British pound. Periodically, the Company will use derivative financial instruments consisting primarily of interest rate hedge agreements to manage exposures to interest rate changes. The
Companys objective in managing its exposure to changes in interest rates on its variable rate debt is to limit their impact on earnings and cash flow and reduce its overall borrowing costs.

At September 30, 2006, the Company had no debt outstanding. Under the Revolving Credit and Security Agreement, substantially all of the Companys borrowings
will bear interest at variable rates based upon the prime rate.

The Companys Marketable securities are invested in stocks and bonds through a
professional investment advisor. Investment securities are exposed to various risks such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in
the value of securities, it is possible that changes in these risk factors could have an adverse material impact on the Companys results of operations or equity.

The Companys sensitivity analysis for interest rate risk excludes accounts receivable, accounts payable and accrued liabilities because of the short-term maturity of such instruments. The analysis does not
consider the effect on other variables such as changes in sales volumes or managements actions with respect to levels of capital expenditures, future acquisitions or planned divestures, all of which could be significantly influenced by changes
in interest rates.

Board of Directors

Gencor Industries, Inc.

Orlando, Florida

We have audited the accompanying consolidated balance sheets of Gencor Industries, Inc. and subsidiaries as of September 30, 2006 and 2005, and the related
consolidated statements of income, shareholders equity and cash flows for the years ended September 30, 2006, 2005 and 2004. Our audits also included the financial statement schedule listed in the accompanying index. These financial
statements and financial statement schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States of America). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of
Gencor Industries, Inc. and subsidiaries as of September 30, 2006 and 2005, and the results of their operations and their cash flows for the years ended September 30, 2006, 2005 and 2004, in conformity with accounting principles generally
accepted in the United States of America. Also, in our opinion, the financial statement schedule referred to above, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

GENCOR INDUSTRIES, INC

Notes to Consolidated Financial Statements

All amounts in thousands, except per share amounts

NOTE 1  NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Gencor Industries, Inc. and its subsidiaries
(collectively the Company) is a diversified heavy machinery manufacturer for the production of highway construction materials, synthetic fuels and environmental control machinery and equipment.

These consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation.

Use of Estimates

The
preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Actual results could differ from those estimates.

Net Income Per Share

The financial statements include basic and
diluted per share information. Basic earnings per share is based on the weighted average number of shares outstanding. Diluted earnings per share is based on the sum of the weighted average number of shares outstanding plus common share equivalents.

The following presents the calculation of the basic and diluted income per share from continuing operations for the years ended September 30, 2006,
2005 and 2004:

Cash Equivalents

Cash equivalents, which consist of short-term certificates of deposit and deposits in money market accounts with original maturities of three months or less, are carried at cost, which approximates their market value.

##### Table of Contents

Marketable Securities

Marketable securities are categorized as trading securities and stated at market value. Market value is determined using the quoted closing or latest bid prices. Realized gains and losses on investment transactions are determined by
specific identification and are recognized as incurred in the statement of income. Net unrealized gains and losses are reported in the statement of income and represent the change in the market value of investment holdings during the period. At
September 30, 2006, Marketable securities consisted of $6,531 in municipal bonds and $29,418 in equity stocks. At September 30, 2005 Marketable securities consist of $5,180 in municipal bonds and $27,607 in equity stocks.

Fair Value of Financial Instruments

The carrying amounts of cash and
cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term nature of these items. The carrying amount of substantially all of the Companys long-term debt approximates fair value due to the
variable nature of the interest rates on the debt.

Foreign Currency Translation

Assets and liabilities of the Companys foreign subsidiaries are translated into U.S. dollars at the applicable rate of exchange in effect at the end of the fiscal year. Revenue and expense accounts are
translated at the average rate of exchange during the period and equity accounts are translated at the rate in effect when the transactions giving rise to the balances took place. Gains and losses resulting from translation are included in
Accumulated Other Comprehensive Income (Loss). Gains and losses resulting from foreign currency transactions are included in income.

Risk
Management

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents,
marketable securities, and accounts receivable. The Company maintains its cash accounts in various domestic and foreign financial institutions. Domestic funds are swept daily into interest-bearing overnight repurchase agreements invested in U.S.
government securities. The marketable securities are invested in stocks and bonds through a professional investment advisor. Investment securities are exposed to various risks such as interest rate, market and credit. The Companys customers
are not concentrated in any specific geographic region, but are concentrated in the road and highway construction industry. The Company extends limited credit to its customers based upon their creditworthiness and generally requires a significant
up-front deposit before beginning construction and full payment subject to hold-back provisions, prior to shipment on asphalt plant orders. The Company establishes an allowance for doubtful accounts based upon the credit risk of specific customers,
historical trends and other pertinent information.

Inventories

Inventories are stated at the lower of cost or market. The Company uses the last-in, first-out (LIFO) method of determining cost for substantially all inventories in the United States. All other inventories are accounted for using the
first-in, first-out (FIFO) method.

Used equipment, acquired by the Company by trade in from customers acquiring new equipment, is valued at estimated net
realizable value at the time of trade in.

Property and Equipment

Property and equipment are
stated at cost. Depreciation of property and equipment, including depreciation on assets acquired under capital leases, is computed using straight-line and accelerated methods over the estimated useful lives of the related assets.

Depreciation of property and equipment, including depreciation on assets acquired under capital leases, is computed using straight-line and accelerated methods over the
estimated useful lives of the related assets as follows:

Impairments

If the carrying value of an asset,
including associated intangibles and goodwill, exceeds the sum of estimated undiscounted future cash flows, an impairment loss is recognized for the difference between estimated fair value and carrying value.

Investment in Unconsolidated Investees

The Company owns a 45%
interest in Carbontronics LLC and a 25% interest in Carbontronics Fuels LLC and Carbontronics II, LLC. These interests were earned as part of value of risk on contracts to build four synthetic fuel production plants during 1998. The Company has no
basis in these equity investments or requirement to provide future funding. The operations of Carbontronics LLC consist of the receipt of contingent payments from the sales of the plants and the distribution thereof to its members. Carbontronics LLC
has no other significant operations or assets. The operations of Carbontronics II, LLC consist of the receipt of royalty payments from the plants and the distribution thereof to its members. Carbontronics II, LLC has no other significant operations
or assets. Any income arising from these investments is dependent upon tax credits (adjusted for operating losses at the fuel plants) being generated as a result of synthetic fuel production, which will be recorded as received. The Company
recognized income of $14,547 in 2006, for the distribution received less an accrual of $1,000 for certain expenses associated with efforts by the Company as plaintiff in a matter against its synthetic fuels partners. The Company received $44,238,
during the fiscal year 2005. The Company received no distributions in fiscal 2004. These distributions are subject to state and Federal income taxes.

Future distributions from these entities depend upon the production of these operations continuing to qualify for tax credits under Section 29 of the Internal Revenue Code and the ability to economically produce and market synthetic
fuel produced by the plants. One of the contingencies related to future benefits from these entities is based on the average price of crude oil. Per a provision of Section 29, if the average price of crude oil reaches a certain level, the tax
credits will terminate. The recent escalation in oil prices raises serious doubt on the continued availability of tax credits under Section 29 for the future. If oil prices remain at the current levels or increase, the tax credits could
phase-out or terminate.

On May 15, 2006, the Company received notification from the administrative partner of these investments that the limited
partners gave notice that the plants should be idled until further notice. They indicated the operations will be curtailed until the earlier of: 1) a legislative change adjusting the determination of the phase-out price, or 2) a downward
movement in oil prices signaling some improved expectation that the credit phase-out will still provide sufficient capital to support the continuation of operations. On October 6, 2006, the Company received notification that the synthetic fuel
plants had resumed operation and on October 18, 2006, the Company received a cash distribution of $3.1 million.

The existing tax credit legislation
is scheduled to expire at the end of calendar year 2007.

Any one of the above eventualities may interrupt, reduce, or terminate further distributions.

Revenues

Revenues from contracts for the design and
manufacture of certain custom equipment are recognized under the percentage-of-completion method. Revenues from all other sales are recorded as the products are shipped or service is performed.

##### Table of Contents

NOTE 1  NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(Continued)

The percentage-of-completion method of accounting for long term contracts recognizes revenue in proportion to actual labor costs incurred as compared
with total estimated labor costs expected to be incurred during the entire contract. All selling, general and administrative expenses are charged to operations as incurred. Provision is made for any anticipated contract losses in the period that the
loss becomes evident.

The estimated costs of product warranties are charged to production costs as revenue is recognized.

Shipping and Handling Costs

Shipping and handling costs are included
in production costs in the statements of income.

Income Taxes

The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns using current tax rates. The Company and its domestic
subsidiaries file a consolidated federal income tax return. The foreign subsidiaries provide income taxes based on the tax regulations of the countries in which they operate. Undistributed earnings of the Companys foreign subsidiaries are
intended to be indefinitely reinvested. No deferred taxes have been provided on these earnings.

Deferred tax assets and liabilities are measured using the
rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse and the credits are expected to be used. The effect on deferred tax assets and liabilities of the change in tax rates is recognized in
income in the period that includes the enactment date. An assessment is made as to whether or not a valuation allowance is required to offset deferred tax assets

Accounting for Stock-Based Compensation

Prior to fiscal 2006, the Company measured compensation expense for employee and director stock
options as the aggregate difference between the market price of the common stock and exercise prices of the options on the date that both the number of shares the grantee is entitled to receive and the purchase price were known. No expense was
recorded as the option prices on grant date were at least equal to market price of the common stock.

Effective October 1, 2005, the Company adopted
the provisions of Financial Accounting Standards Board Statement No. 123R Share-Based Payment (SFAS No. 123R). The Company now records grant-date fair value of stock-based compensation in the statement of operations. The
Company adopted SFAS 123R using the modified prospective method. Accordingly, the Company has not restated any previous operating results.

On
September 28, 2006, the Company granted 30,000 options at market price to certain officers and directors of the Company. The fair value is estimated on grant date using the Black-Scholes options pricing model. Volatility was based on historical
activity and the term was estimated based on the life of the option and the vesting period. As a result, $270 of unearned compensation was recorded at September 30, 2006 and will be charged to operating expense over the vesting period of two
years.

Comprehensive Income (Loss)

Other
Comprehensive Income (Loss) consists of net income and includes all other changes in shareholders equity except those resulting from investments by owners and distributions to them. For all years presented, the Companys comprehensive
income (loss), which encompasses net income and foreign currency translation adjustments, is separately displayed in the consolidated statement of shareholders equity.

options and nonqualified stock options to purchase up to 1,200,000 shares of the Companys Common Stock, 1,200,000 shares of the Companys Class B Stock and up to fifteen percent (15%) of the authorized Common Stock of any
subsidiary.

Under the terms of the Plans, option holders may tender previously owned shares with a market value equal to the exercise price of the options
at exercise date, subject to Compensation Committee approval. Additionally, option holders may, upon Compensation Committee approval, surrender shares of stock to satisfy federal withholding tax requirements.

Options become exercisable in a manner and on such dates and times as determined by a committee of the Board of Directors. Options expire not more than ten years from
the date of grant. The option holders have no shareholder rights until the date of issuance of a stock certificate for such shares. Exercise of the options granted during 2002 and 2001 are limited to 20% per year over the next 5 years.

During 2005, 1,322,000 options were exercised at prices ranging from $1.65-$1.82 per share for a total of $2,331 and was paid to the Company with 259,000

years and are exercisable through 2016. The fair value of these options is estimated on grant date using the Black-Scholes options pricing model. As a result, $270 of unearned compensation was recorded at September 30, 2006 and will be charged
to operating expense over the vesting period of two years. As of September 30, 2006, the Company has 1,450,000 options available for future grants under the plans.
