PART I

Company Background and Corporate Structure

American Electric Technologies, Inc. (the “Company”, “AETI”, “our”, “us” or “we”) was incorporated on October 21, 1996 as a Florida corporation under the name American Access Technologies, Inc. On May 15, 2007, we completed a business combination (the “M&I Merger”) with M&I Electric Industries, Inc. (“M&I”), a Texas corporation, and changed our name to American Electric Technologies, Inc. Our principal executive offices are located at 6410 Long Drive, Houston, Texas 77087 and our telephone number is 713-644-8182. Prior to the M&I Merger, our business consisted of the operations of the American Access segment described below.

Our corporate structure currently consists of American Electric Technologies, Inc., which owns 100% of both M&I Electric Industries, Inc. and American Access Technologies, Inc. (“AAT”). The Company reports financial data for three operating segments: the Technical Products and Services (“TP&S”) segment and the Electrical and Instrumentation Construction (“E&I”) segment; which together encompass the operations of M&I, including its wholly-owned subsidiary, South Coast Electric Systems, LLC and its interest in international joint ventures’ operations in China, Singapore and Brazil; and the American Access (“AAT”) segment which encompasses the operations of our wholly-owned subsidiary, American Access Technologies, Inc., including its Omega Metals division.

We are a leading provider of power delivery solutions to the global energy industry.

The principal markets and representative customer types that we serve include:

A key component of our company’s strategy is our international focus. We have two primary models for conducting our international business. First, we sell directly and through foreign sales agents that we have appointed. Many of those international partners also provide local service and support for our products in those overseas markets. Second, where local market conditions dictate, we have expanded internationally by forming joint venture operations with local companies in key markets such as China, Brazil and Singapore, where there are local content requirements or we need to do local manufacturing.

Our business strategy is to grow through organic growth in our key energy markets, to expand our solution set to our current market segments, to continue our international expansion, and to accelerate those efforts with acquisitions, while at the same time increasing earnings and cash flow per share to enhance overall stockholder value.

We have recently designed and brought to market products for utility level solar energy projects, including solar inversion systems and utility interconnect systems. We also provide installation and commissioning services for these systems.

We are uniquely positioned to be the “turn-key” supplier for power delivery projects for our customers, where we are able to offer custom-designed power distribution and power conversion systems, power services, and electrical and instrumentation construction, all from one company.

Technical Products and Services

Our M&I Electric business has provided sophisticated custom-designed power distribution, power conversion and control and automation systems for the energy industry since 1946. Our products are used to safely distribute and control the flow of electricity from the source of the power being generated (e.g. a diesel generator or the utility grid) to whatever mechanical device needs to use the power (machinery, equipment, etc.) at low, medium and high voltages.

Table of Contents

Our power distribution products include low and medium voltage switchgear that provide power distribution and protection for electrical systems from electrical faults for both ANSI (“American National Standards Institute”) and IEC (“International Electrotechnical Commission”) markets. Other power distribution products offered by us include motor control centers, powerhouses, bus ducts, program logic control (“PLC”) based automation systems, human machine interface (“HMI”) and specialty panels.

Our Analog, Digital SCR (“silicon controlled rectifier”) and Alternating Current Variable Frequency Drive (“AC VFD”) systems are electronic power conversion systems that are used to adjust the speed and torque of an electric motor to match various user applications.

On March 8, 2012, the Company acquired the technology of Amnor Technologies, Inc. This technology provides automation and control system technologies for land and offshore drilling monitoring and control (auto-driller); marine automation including ballast control, tank monitoring, and machinery plant control and monitoring systems; Internet Protocol (IP)-based Controlled Circuit TV systems; and vessel management software systems, all proven in multiple installations.

We have the technical expertise to provide these products in compliance with a number of applicable industry standards such as NEMA (“National Electrical Manufacturers Association”) and ANSI or IEC equipment to meet ABS (“American Bureau of Shipping”), USCG (“United States Coast Guard”), Lloyd’s Register, a provider of marine certification services, and Det Norske Veritas (a leading certification body/registrar for management systems certification services) standards. These products are generally provided to customers within the vicinity of Houston, Texas and increasingly on a worldwide basis.

Our customers for these products are typically large and sophisticated generators and users of electrical power.

Our power distribution and control products are generally custom-designed to our customers’ specific requirements, and we do not maintain an inventory of such products.

Our technical services group provides low, medium and high voltage services to commission and maintain our customers’ electrical infrastructures. We provide low, medium and high voltage start-up/commissioning, preventative maintenance, emergency call out services, and breaker and switchgear refurbishment shop services to the Gulf Coast industrial market. We have expanded our services business to provide start-up and maintenance services for renewable projects, including wind and solar. We also provide power services to support our power distribution and power conversion products globally.

Foreign Joint Ventures

We primarily use foreign joint ventures to drive growth in key international markets. We believe our joint ventures provide a prudent way to diversify and reduce the risk of international expansion, capitalize on the strengths and the relationships of our joint venture foreign operation partners with potential customers, and achieve competitive advantages. Our interests in joint ventures are accounted for under the equity method of accounting. Sales made to the joint ventures are made with terms and conditions similar to those of our other customers.

China. In March 2006, M&I Electric entered into a joint venture with Baoji Oilfield Machinery Co., Ltd., (“BOMCO”), a wholly-owned subsidiary of the China National Petroleum Corporation, and AA Energies, Inc. of Houston, Texas, which markets oilfield equipment, to form BOMAY Electric Industries Co., Ltd. (“BOMAY”), as an equity joint venture limited liability company organized in China. M&I is a 40% interest owner in BOMAY with 51% being owned by BOMCO and the remaining 9% owned by AA Energies, Inc. BOMAY manufactures power systems for drilling rigs. M&I has invested 16 million Yuan (approximately $2 million) in this joint venture in which M&I provides technology and services to BOMAY. Each of the BOMAY investors may be required to guarantee the bank loans of BOMAY in proportion to their investment. No guarantees have been provided by AETI. BOMAY was obligated to pay M&I an amount equal to 0.7% of the joint venture’s initial three years sales as a technology transfer fee. The technology transfer fee ended at the end of 2010 by its terms.

Singapore. In 1994, the Company formed a joint venture in Singapore to provide sales and technical support for our products in Southeast Asia called M & I Electric Far East PTE Ltd. (“MIEFE”). Prior to December 31, 2011, the Company owned 49% of the joint venture with our joint venture partner, Oakwell Engineering, Ltd., owning the remaining 51%. On December 31 2011, we exchanged 8% of our MIEFE ownership for satisfaction of amounts owed to MIEFE’s general manager, under a deferred compensation arrangement of approximately $190,000.

Brazil. During 2010, the Company entered into a joint venture agreement with Five Star Services, a Brazilian corporation, and formed AETI Alliance Group do Brazil Sistemas E Servicos Em Energia LTDA (“AAG”), a Brazilian Limited Liability Company, in which the Company holds a 49% interest. AAG began operations mid-year 2010, and provides electrical products and services to the Brazilian energy industries. The Company has invested $54,000 and has advanced $180,000 to AAG as of December 31, 2012 per the agreement.

Investment in Foreign Joint Ventures:

During 2012 and 2011, the Company recognized approximately $343,000 and $437,000, respectively, for employee joint venture related expenses and included as Foreign Joint Ventures Operation’s Related Expenses in accompanying statements of operations.

Electrical and Instrumentation Construction

The Electrical and Instrumentation Construction (“E&I”) segment provides a full range of electrical and instrumentation construction and installation services to the Company’s markets. This segment’s services include new construction as well as electrical and instrumentation turnarounds, maintenance and renovation projects. Applications include installation of switchgear, AC and DC motors, drives, motor controls, lighting systems and high voltage cable.

Marine based oil and gas services include complete electrical system rig-ups, modifications, start-ups and testing for vessels, drilling rigs, and production modules. In 2012, the Company announced it was phasing out of the municipal water wastewater construction market, which is expected to be complete in 2013. The Company is focusing its construction efforts on strategic segments including oil & gas, power generation and distribution and marine and non oil & gas industrial.

Marketing

We market our Technical Products and Services in the United States through direct contact with potential customers by our internal sales organization consisting of eight full-time sales and support employees. We also exhibit at a variety of industry trade shows each year. We have appointed several sales agents and distributors in the United States and in a number of foreign countries.

Our E&I business is generally obtained through a bid process where the lowest bid from pre-qualified contractors is awarded the project. We act as a subcontractor and provide bids to general contractors or Engineering, Procurement and Construction (“EPC”) firms for specialized parts of larger projects.

Our AAT segment markets its zone cabling products through an exclusive marketing agreement with Chatsworth Products, Inc. (“CPI”) which began under an original agreement in May, 2003 that ran through May, 2008 and was extended to April, 2013. Under this agreement, CPI markets and American Access manufactures our zone cabling products and select products are co-branded with both CPI and American Access trademarks. We also have primary responsibility for sales of zone cabling products to original equipment manufacturers. Our Omega Metals division utilizes geographically based independent manufacturers’ representatives to generate sheet metal fabrication sales.

Manufacturing

Manufacturing processes at our various facilities include machining, fabrication, subassembly, system assembly and final testing. We have invested in various automated and semi-automated equipment for the fabrication and machining of various parts and assemblies that we incorporate into our products. Our quality assurance program includes various quality control measures from inspection of raw material, purchased parts and assemblies through on-line inspection. We perform system design, assembly and testing in-house. Our manufacturing operations in Beaumont, Texas and Keystone Heights, Florida are ISO 9001:2008 certified.

Raw Materials and Suppliers

The principal raw materials for our products are copper, steel, aluminum and various manufactured electrical components. We obtain these products from a number of domestic and foreign suppliers. The market for most of the raw materials and parts we use is comprised of numerous participants and we believe that we can obtain each of the raw materials we require from more than one supplier. We do not have any long-term contractual arrangements with the suppliers of our raw materials.

Competition

Our products and services are sold in highly competitive markets. We compete in all areas of our operations with a number of companies, some of which have financial and other resources comparable to or greater than us. Due to the demanding operating conditions in the energy sector and the high costs associated with project delays and equipment failure, we believe customers in this industry prefer suppliers with a track record of reliable performance. We seek to build strong long-term relationships with our customers by maintaining our reputation as a provider of high-quality, efficient and reliable products and services, by developing new products and services and by responding promptly to our customers’ needs.

The principal competitive factors in our markets are product and service quality and reliability, lead time, price, technical expertise and reputation.

We believe our principal competitive strengths include the following:

Our power delivery, control and drive systems are custom-designed and are built to meet our customers’ specific requirements. We specialize in projects that are complex, require industry certification, have short lead times or other non-standard elements, such as systems that must be deployed in harsh environments or need to meet tight space or weight requirements. Our ability to provide custom-designed technical products, electrical and instrumentation construction services, and electrical startup and preventative maintenance services is unique, enabling us to provide customers total system responsibility for their electrical power control and distribution needs. We have a history of innovation in developing and commercializing new technologies into our products. Examples include digitally controlled drives, liquid-cooled high horsepower AC VFDs which are optimized for space-constrained offshore and marine applications and American Access’ zone cabling solutions. We have also expanded the market for our products both internationally and to additional end-user markets.

Our commitment to providing quality products and services, fair pricing, innovation and customer service is the foundation to the long-standing customer relationships that we enjoy with an attractive customer base. Since 1946, we have provided over 10,000 power delivery systems to many of the leading companies involved in oil and gas exploration, drilling, production, pipelines, shipbuilding, oil refineries, petrochemicals, power generation, and steel industries in the Gulf Coast region of the United States.

We are led by an experienced management team with a proven track record. We believe the experience of our management team provides us with an in-depth understanding of our customers’ needs and enhances our ability to deliver customer-driven solutions. We believe our management has fostered a culture of loyalty, resulting in high employee retention rates for our professional and technical employees.

Backlog

Backlog represents the dollar amount of net sales that we expect to realize in the future as a result of performing work under multi-month contracts. Backlog is not a measure defined by generally accepted accounting principles, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog. Backlog may not be indicative of future operating results. Not all of our potential net sales are recorded in backlog for a variety of reasons, including the fact that some contracts begin and end within a short-term period. Many contracts are subject to modification or termination by the customer. The termination or modification of any one or more sizeable contracts or the addition of other contracts may have a substantial and immediate effect on backlog. This backlog number does not include any backlog in place at our foreign joint ventures’ operations.

We generally include total expected net sales in backlog when a contract for a definitive amount of work is entered into. We generally expect our backlog to become net sales within a year from the signing of a contract. Backlog as of December 31, 2012 and 2011 totaled $15.5 million and $21.2 million, respectively.

Intellectual Property

We have a number of patents related to the technology of our zone cabling enclosures as well as trademarks and trade names utilized with our products and services. While proprietary intellectual property is important to the Company, management believes the loss or expiration of any intellectual property right would not materially impact the Company or any of its segments.

Environmental Laws

We are subject to various federal, state, and local laws enacted for the protection of the environment. We believe we are in compliance with such laws. Our compliance has, to date, had no material effect on our capital expenditures, earnings, or competitive position.

Research and Development Costs

Total expenditures for research and development were $103,000 and $577,000 for the fiscal years ended December 31, 2012 and 2011. We incurred research costs to develop new products which related to the continued development of the Company’s ISIS products, our Integrated Solar Inversion Station for the solar power generation market.

Employees

As of December 31, 2012, we had 312 employees. No employees are covered by a collective bargaining agreement, and we consider our relations with our employees to be satisfactory.

You should carefully consider each of the following risks associated with an investment in our common stock and all of the other information in this 2012 Annual Report on Form 10-K. Our business may also be adversely affected by risks and uncertainties not presently known to us or that we currently believe to be immaterial. If any of the events contemplated by the following discussion of risks should occur, our business, prospects, financial condition and results of operations may suffer.

Customers in the oil and gas industry account for a significant portion of our sales. Reduced expenditures by customers in this industry are likely to reduce our net sales, profitability and cash flows.

Customers related to the oil and gas industry accounted for approximately 68% and 35% of our sales in 2012 and 2011, respectively. The oil and gas industry is a cyclical commodity business, with product demand and prices based on numerous factors

8

Table of Contents

such as general economic conditions and local, regional and global events and conditions that affect supply, demand and profits. Demand for our products and services benefits from oil and gas markets, a decline in demand or prices for oil and gas will likely cause a decrease in demand for our products and services and result in a decline in our net sales, profit margins and cash flows.

Our products include complex systems for energy and industrial markets which are subject to operational and liability risks.

We are engaged in the manufacture and installation of complex power distribution and control systems for the energy and industrial markets. These systems are frequently complex and susceptible to unique engineering elements that are not tested in the actual operating environment until commissioned. As a result, we may incur unanticipated additional operating and warranty expenses that were not anticipated when the fixed-price contracts were estimated and executed resulting in reduced profit margins on such projects.

The industries in which we operate are highly competitive, which may result in a loss of market share or decrease in net sales or profit margin.

Our products and services are provided in a highly competitive environment and we are subject to competition from a number of similarly sized or larger businesses which may have greater financial and other resources than are available to us. Factors that affect competition include timely delivery of products and services, reputation, manufacturing capabilities, price, performance and dependability. Any failure to adapt to a changing competitive environment may result in a loss of market share and a decrease in net sales and profit margins.

We often utilize fixed-price contracts which could adversely affect our financial results.

We currently generate, and expect to continue to generate, a significant portion of our net sales under fixed-price contracts. We must estimate the costs of completing a particular project to bid for such fixed-price contracts. The cost of labor and materials, however, may vary from the costs we originally estimated. These variations, along with other risks inherent in performing fixed-price contracts, may result in actual costs and gross profits for a project differing from those we originally estimated and could result in reduced profitability and losses on projects. Depending upon the size of fixed-price contracts, variations from estimated contract costs can have a significant impact on our operating results for any fiscal quarter or year.

Our use of percentage-of-completion accounting could result in a reduction or elimination of previously reported profit.

A portion of our net sales is recognized on the percentage-of-completion method of accounting. The percentage-of-completion method of accounting practice we use results in recognizing contract net sales and earnings ratably over the contract term in proportion to our incurrence of contract costs. The earnings or losses recognized on individual contracts are based on estimates of contract net sales, costs and profitability. Contract losses are recognized in full when determined, and contract profit estimates are adjusted based on ongoing reviews of contract profitability. Actual collection of contract amounts or change orders could differ from estimated amounts and could result in a reduction or elimination of previously recognized earnings. In certain circumstances, it is possible that such adjustments could be significant.

We may not be able to fully realize the net sales value reported in our backlog.

Orders included in our backlog are represented by customer purchase orders and contracts. Backlog develops as a result of new business which represents the net sales value of new project commitments received by us during a given period. Backlog consists of projects which have either (1) not yet been started or (2) are in progress and are not yet complete. In the latter case, the net sales value reported in backlog is the remaining value associated with work that has not yet been completed. From time to time, projects that were recorded as new business are cancelled. In the event of a project cancellation, we may be reimbursed for certain costs but typically have no contractual right to the total net sales included in our backlog. In addition to being unable to recover certain direct costs, we may also incur additional costs resulting from underutilized assets if projects are cancelled.

We rely on a few key employees whose absence or loss could disrupt our operations or be adverse to our business.

Our continued success is dependent on the continuity of several key management, operating and technical personnel. The loss of these key employees would have a negative impact on our future growth and profitability. We have entered into written employment agreements with our Chief Executive Officer, Chief Financial Officer and Executive Chairman.

Our results of operations and financial condition may be adversely impacted by global recession.

The consequences of a prolonged recession could include a lower level of economic activity and uncertainty regarding commodity and capital markets. During early 2012 and 2011, we experienced a reduction in the demand for our products as a result of a reduction in economic activity. The lack of a sustained recovery could continue to have an adverse effect on our results of operations, cash flows or financial position.

Table of Contents

Our failure to attract and retain qualified personnel could lead to a loss of net sales or profitability.

Our ability to provide high-quality products and services on a timely basis requires that we employ an adequate number of skilled personnel. Accordingly, our ability to increase our productivity and profitability will be limited by our ability to employ, train and retain skilled personnel necessary to meet our requirements. We cannot be certain that we will be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our growth strategy or that our labor expenses will not increase as a result of a shortage in the supply of skilled personnel.

Natural disasters, terrorism, acts of war, international conflicts or other disruptions could harm our business and operations.

Natural disasters, acts or threats of war or terrorism, international conflicts, and the actions taken by the United States and other governments in response to such events could cause damage to or disrupt our business operations or those of our customers, any of which could have an adverse effect on our business.

We manufacture products and operate plants in Mississippi, Texas and Florida. Operations were disrupted in 2008 due to Hurricanes Gustav and Ike and in 2005 due to Hurricanes Katrina and Rita. Although we did not suffer a material loss as a result of these disruptions due to our insurance coverage and advance preparations, it is not possible to predict future similar events or their consequences, any of which could decrease demand for our products, make it difficult or impossible for us to deliver products, or disrupt our supply chain.

We generate a significant portion of our net sales from international operations and are subject to the risks of doing business outside of the United States.

Approximately 26% of our net sales in 2012 were generated from projects and business operations outside of the United States, primarily provided to the oil and gas, drilling and marine industries in the following countries: Mexico, Canada, United Arab Emirates, India and Brazil. This percentage was approximately 36% in 2011. The oil and gas industry operates in both remote and potentially politically unstable locations, and numerous risks and uncertainties affect our non-United States operations. These risks and uncertainties include changes in political, economic and social environments, local labor conditions, changes in laws, regulations and policies of foreign governments, as well as United States laws affecting activities of United States companies abroad, including tax laws and enforcement of contract and intellectual property rights. In addition, the costs of providing our services can be adversely and/or unexpectedly impacted by the remoteness of the locations and other logistical factors.

We maintain a significant investment in a joint venture with a Chinese energy company. We may encounter unforeseen or unexpected operating, financial, political or cultural factors that could impact its business plans and the expected profitability from such investment. We will face risks if China loses normal trade relations with the United States and it may be adversely affected by the diplomatic and political relationships between the United States and China. As a result of the relatively weak Chinese legal system, in general, and the intellectual property regime, in particular, we may face additional risk with respect to the protection of our intellectual property in China. Changes in China’s political and economic policies could adversely affect our investment and business opportunities in China.

The marketplace may not accept and utilize our newly developed solar products and services, the effect of which would prevent us from successfully commercializing any proposed products or services and adversely affect our level of future net sales for these solar products.

Our ability to market and commercialize our products and services for the manufacture and distribution of the newly developed solar products directly depends on the acceptance of such products and services by the industry. The development of many solar projects is also dependent upon the availability of governmental subsidies and tax benefits which may be reduced or eliminated due to fiscal or political considerations.

Foreign Currency Transaction Risk

AETI maintains equity method investments in its Singapore, Chinese and Brazilian joint ventures, MIEFE, BOMAY, and AAG, respectively. The functional currencies of the joint ventures are the Singapore Dollar, the Chinese Yuan and the Brazilian Real, respectively. Investments are translated into United States Dollars at the exchange rate in effect at the end of each quarterly reporting period. The resulting translation adjustment is recorded as accumulated other comprehensive income, net of deferred taxes in AETI’s consolidated balance sheet. This item increased from $849,000 at December 31, 2011 to $900,000 at December 31, 2012 due to the weakness of the United States Dollar against the Chinese Yuan and Singapore Dollar partially offset by weakness of the Brazilian Real to the United States Dollar.

Other than the aforementioned items, we do not believe we are exposed to foreign currency exchange risk because all of our net sales and purchases are denominated in United States Dollars.

Table of Contents

Commodity Price Risk

We are subject to market risk from fluctuating market prices of certain raw materials. While such materials are typically available from numerous suppliers, commodity raw materials are subject to price fluctuations. We endeavor to recoup any price increases from our customers on an individual contract basis to avoid operating margin erosion. Although historically we have not entered into any contracts to hedge commodity risk, we may do so in the future.

Commodity price changes can have a material impact on our prospective earnings and cash flows. Copper, steel and aluminum represent a significant element of our material cost. Significant increases in the prices of these materials could reduce our estimated operating margins if we are unable to recover such increases from customer net sales.

Interest Rates

Our market risk sensitive items do not subject us to material risk exposures. Our revolving credit facility remains available through July 1, 2014. At December 31, 2012, the Company had $0.5 million of variable-rate debt outstanding under the facility. At this borrowing level, a hypothetical relative increase of 10% in interest rates would have had an insignificant, unfavorable impact on the Company’s pretax earnings and cash flows. The primary interest rate exposure on variable-rate debt is based on the 90 day LIBOR rate (0.3% at December 31, 2012) plus 3.25% per year. The agreement is collateralized by trade accounts receivable, inventory, work-in-process, equipment and real property located in Beaumont and Houston, TX.

None

The following table describes the material facilities of AETI and its subsidiaries, including foreign joint ventures, as of December 31, 2012:

The Company becomes involved in various legal proceedings and claims in the normal course of business. In management’s opinion, the ultimate resolution of these matters is not expected to have a material effect on our consolidated financial position or results of operations.

None.

Overview

Our corporate structure currently consists of American Electric Technologies, Inc., which owns 100% of both M&I and AAT. We report financial data for three operating segments: the TP&S segment and the E&I segment which together encompass the operations of M&I including its South Coast Electric Systems, LLC subsidiary and the AAT segment which encompasses the operations of AAT including its wholly-owned Omega Metals division. In addition, M&I holds a 40%, 41%, and 49% interest in China, Singapore, and Brazil foreign joint ventures’ operations, respectively. Prior to December 31, 2011, the Company owned 49% of the Singapore’s joint venture with our joint venture partner, Oakwell Engineering, Ltd., owning the remaining 51%. At December 31^st 2011, we exchanged 8% of our MIEFE ownership for satisfaction of amounts owed to MIEFE’s general manager, under a deferred compensation arrangement for approximately $190,000. These ventures are stand-alone operating companies and enhance our ability to provide products to these markets. Results from these ventures are reported using the equity method of accounting.

Non-GAAP Financial Measures

A non-GAAP financial measure is generally defined as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so adjusted in the most comparable GAAP measure. In this report, we define and use the non-GAAP financial measure EBITDA as set forth below.

EBITDA

Definition of EBITDA

We define EBITDA as follows:

Net income (loss) before:

Management’s Use of EBITDA

We use EBITDA to assess our overall financial and operating performance. We believe this non-GAAP measure, as we have defined it, is helpful in identifying trends in our day-to-day performance because the items excluded have little or no significance on our day-to-day operations. This measure provides an assessment of controllable expenses and affords management the ability to make decisions which are expected to facilitate meeting current financial goals as well as achieving optimal financial performance. It provides an indicator for management to determine if adjustments to current spending decisions are needed.

Table of Contents

EBITDA provides us with a measure of financial performance, independent of items that are beyond the control of management in the short-term, such as dividends required on preferred stock, depreciation and amortization, taxation and interest expense associated with our capital structure. This metric measures our financial performance based on operational factors that management can impact in the short-term, namely the cost structure or expenses of the organization. EBITDA is one of the metrics used by senior management and the board of directors to review the financial performance of the business on a regular basis. EBITDA is also used by research analysts and investors to evaluate the performance of and value companies in our industry.

Limitations of EBITDA

EBITDA has limitations as an analytical tool. It should not be viewed in isolation or as a substitute for GAAP measures of earnings. Material limitations in making the adjustments to our earnings to calculate EBITDA, and using this non-GAAP financial measure as compared to GAAP net income (loss), include:

An investor or potential investor may find this item important in evaluating our performance, results of operations and financial position. We use non-GAAP financial measures to supplement our GAAP results in order to provide a more complete understanding of the factors and trends affecting our business.

EBITDA is not an alternative to net income, income from operations or cash flows provided by or used in operations as calculated and presented in accordance with GAAP. You should not rely on EBITDA as a substitute for any such GAAP financial measure. We strongly urge you to review the reconciliation of EBITDA to GAAP net income (loss) attributable to common stockholders, along with our condensed consolidated financial statements included herein.

We also strongly urge you to not rely on any single financial measure to evaluate our business. In addition, because EBITDA is not a measure of financial performance under GAAP and is susceptible to varying calculations, the EBITDA measure, as presented in this report, may differ from and may not be comparable to similarly titled measures used by other companies.

The Company’s investment in and advances to its foreign joint ventures’ operations were as follows as of December 31, 2012 and 2011:

The Company accounts for its investments in foreign joint ventures’ operations using the equity method of accounting. Under the equity method, the Company’s share of the joint ventures’ operations’ earnings or loss is recognized in the consolidated statements of operations as equity income (loss) from foreign joint ventures’ operations. Joint venture income increases the carrying value of the joint ventures and joint venture losses reduce the carrying value. Dividends received from the joint ventures reduce the carrying value.

Results of Operations

The table below summarizes our consolidated net sales and profitability for the years ended December 31, 2012, 2011 and 2010 (dollars in thousands):

Year ended December 31, 2012 compared to year ended December 31, 2011

Consolidated net sales increased $2.1 million or 4%, to $54.1 million for the year ended December 31, 2012 as compared to 2011. The Company’s net sales growth from the comparative prior year period was driven primarily by increased demand for its Technical Products which was partially offset by declines in Electrical Instrumentation and Construction. These declines in the E&I segment relate primarily to the Company’s decision in 2012 to exit the water/wastewater construction business to focus its E&I efforts on more strategic segments including oil & gas, power generation and distribution, and marine and non oil & gas industrial.

Consolidated gross profit increased $1.0 million to $8.1 million and increased as a percentage of net sales from 14% to 15%. This increase was mainly attributable to the TP&S segment’s increased net sales and direct margin compared to the previous period in 2011. This performance reflects the improved business environment and benefits of the cost reduction efforts implemented in late 2010. The Company’s gross profit reported each quarter in 2012 was $1.8 million in the first quarter, $2.2 million in the second quarter, $1.6 million in the third quarter and $2.5 million in the fourth quarter.

Segment Comparisons

The TP&S segment’s net sales increased $10.0 million from $28.9 million for the year ended December 31, 2011, to $39.0 million for the year ended December 31, 2012, a 35% improvement. Gross profit for the segment for the year ended December 31, 2012 was $6.6 million, an increase of $2.1 million over the prior year gross profit of $4.6 million. The increase in Technical Products and Services results was driven in large part by increased mid and downstream oil and gas demand for our products and services during 2012 which more than offset a slowdown in the domestic land and offshore rig markets.

The E&I segment’s reported net sales of $9.2 million for the year ended December 31, 2012, a decrease of $6.3 million, or 41%, compared to the year ended December 21, 2011. The results reflect our decision to exit the water/wastewater business and focus our Electrical and Instrumentation construction efforts on markets that are more closely aligned with our overall strategy. Gross profit for the E&I segment during the year ended December 31, 2012 was $0.5 million, compared to $1.2 million in the corresponding prior year period. Gross profit as a percentage of net sales decreased to 6% from 8% in the comparable prior period, due to the winding down of existing contractual arrangements and the consolidation of our Beaumont and Houston construction resources.

The AAT segment reported net sales of $5.9 million for the year ended December 31, 2012, down $1.6 million, from the comparable prior year period, a 22% decrease. Gross profit decreased by $0.4 million in 2012, from $1.3 million in the prior year. Gross profit as a percentage of net sales decreased to 16% in 2012 from 18% in the comparable prior period. The decline in the AAT segments revenue and profitability primarily relates to the loss of a key contract. This segment continues to be challenged by competitive pricing due to weakness in the industrial sector and the loss of a key account. While we continue to work to improve the results, we do not anticipate AAT to return to 2011 revenue levels during 2013.

Research and development costs for the year ended December 31, 2012 were down to $0.1 million from $0.6 million in the previous period, all of which related to the continued development of the Company’s ISIS products. We anticipate increased research and development expenditures in 2013 as we develop new products to meet the needs of our customers.

Selling and marketing expenses for the year ended December 31, 2012 were $2.5 million, or 5% of net sales and essentially unchanged when compared to 2011.

General and administrative expenses were down for the year ended December 31, 2012 over the same period in 2011 by $0.6 million from $5.8 million in 2011 to $5.2 million in 2012 primarily due to a legal expense of $0.4 million in 2011 related to the E&I segment’s arbitration dispute, from which the Company received a favorable determination from the binding arbitrator. In addition, the Company recorded an additional audit expense accrual of $252,000 in 2011.

Net equity income from foreign joint ventures increased for the year ended December 31, 2012 by $1.3 million to $2.8 million when compared to the period ended December 31, 2011. The increased equity income resulted primarily from BOMAY, which increased from $1.7 million in 2011 to $2.6 million in 2012 as a result of increased activity in China.

Consolidated other expense, net was $148,000 for the year ended December 31, 2012, a decrease of $68,000 from the comparable prior year, primarily due to a reduction of long-term debt. Long-term debt decreased from $5.1 million at the end of 2011 to $0.5 million at December 31, 2012 as a result of a $5 million preferred stock issuance.

The (provision for) benefit from income taxes for the year ended December 31, 2011 was a non-cash expense of $5.4 million which reflects the valuation allowance related to the Company’s net deferred tax assets related to its U.S. operations. The deferred tax asset was primarily related to the net operating loss carry forwards of $9.8 million generated by AAT prior to the Company’s merger in 2007. Subsequently, the Company generated additional net operating losses and foreign tax credit carry forwards. It was determined in the fourth quarter of 2011 that due to the Internal Revenue’s Section 382 limitations on our ability to utilize the net operating losses and due to three years of cumulative losses, a full valuation allowance was warranted and as such, an expense was recorded. See Note 7 to the Consolidated Financial Statements included in this report for further details. The 2012 tax accrual represents U.S. taxes on the equity income less dividends received.

Year ended December 31, 2011 compared to year ended December 31, 2010

Consolidated net sales increased $13.0 million or 33%, to $51.9 million for the year ended December 31, 2011 over the comparable period in 2010. The Company’s reporting segments showed strong net sales growth from the comparative period primarily due to increased demand for its technical products related to the U. S. land drilling market.

Consolidated gross profit increased $3.5 million to $7.2 million and increased as a percentage of net sales from 9% to 14%. This increase was mainly attributable to the TP&S segment’s increased net sales and direct margin compared to the previous period in 2010, as well as a reduction of the Company’s indirect costs of sales expenses of approximately $1.4 million for the year ended December 31, 2011. This performance reflects the improving conditions in the land drilling markets and benefits of the cost reduction efforts implemented in late 2010. The Company’s gross profit reported each quarter in 2011 was $1.2 million in the first quarter, $1.5 million in the second quarter, $2.2 million in the third quarter and $2.3 million in the fourth quarter which reflected a continued improvement with each quarter. In the four quarter 2011, the Company wrote down its AAT inventory by $276,000 as a charge to cost of sales which reflected a change in the labor and overhead absorption rates in inventory.

Segment Comparisons

The TP&S segment’s net sales increased $8.3 million from $20.6 million for the year ended December 31, 2010, to $28.9 million for the year ended December 31, 2011, a 41% improvement which reflects the increase in the land drilling market. Gross profit for the segment for the year ended December 31, 2011 was $4.6 million, an increase of $3.4 million over the prior year gross profit of $1.2 million. In 2010, the Company implemented cost saving initiatives which reduced indirect expense by $1.1 million in 2011 over 2010.

The E&I segment reported net sales of $15.5 million for the year ended December 31, 2011, an increase of $4.0 million, or 35%, over the year ended December 31, 2010 which primarily reflected an improvement in the water/wastewater projects developed in municipalities. Gross profit for the E&I segment during the year ended December 31, 2011 was $1.2 million, compared to $834,000 in the corresponding prior year period. Although gross profit as a percentage of net sales increased to 8% from 7% in the comparable prior period, the water/wastewater market continues to be competitive with fixed-priced projects. Indirect costs during 2011 declined by $314,000 which benefited the gross profit.

The AAT segment reported net sales of $7.5 million for the year ended December 31, 2011, up $655,000 from the comparable prior year period, a 10% increase. Gross profit decreased by $334,000 in 2011, from $1.7 million in the prior year period. Gross profit as a percentage of net sales decreased to 18% in 2011from 24% in the comparable prior period. In the fourth quarter 2011, the Company wrote down its AAT inventory by $276,000 as a charge to cost of sales which reflected a change in the labor and overhead absorption rates in inventory. This segment continues to be challenged by competitive pricing due to weakness in the industrial sector.

Research and development costs for the year ended December 31, 2011 were down to $557,000 from $882,000 in the previous period, all of which related to the continued development of the Company’s ISIS products.

Selling and marketing expenses for the year ended December 31, 2011 were $2.5 million, or 5% of net sales compared to the prior year period ended December 31, 2010 of $2.3 million, or 6% of net sales. The dollar increase is primarily attributable to increased commissions related to the $13.0 million increase in net sales and an increase in marketing trade shows of approximately $130,000.

General and administrative expenses were up for the year ended December 31, 2011 over the same period in 2010 by $947,000 due to an increase in Company’s variable compensation expense of $364,000 and legal expenses of $368,000 related to the E&I segment’s arbitration dispute, from which the Company received a favorable determination from the binding arbitrator. In addition, the Company recorded an additional audit expense accrual of $252,000 in 2011.

Net equity income from foreign joint ventures’ operations decreased for the year ended December 31, 2011 by $388,000 to $1.5 million as compared to the prior year period ended December 31, 2010. Equity income from foreign joint ventures for the year ended December 31, 2010, benefited from the reversal of a $660,000 expense accrual recorded in 2007 associated with the BOMAY joint venture of which management determined in 2010 was no longer necessary.

Consolidated other expense, net was $216,000 for the year ended December 31, 2011, a decrease of $102,000 from the comparable prior year. The decrease primarily resulted from a $200,000 customer settlement in 2010 partially offset by an increase in interest expense due to a $1.0 million increase in outstanding debt in the revolving credit balance and higher interest rates in 2011.

The (provision for) benefit from income taxes for the year ended December 31, 2011 was a non-cash expense of $5.4 million which reflects the valuation allowance related to the Company’s net deferred tax assets related to its U.S. operations. The deferred tax asset was primarily related to the net operating loss carry forwards of $9.8 million generated by AAT prior to the Company’s merger in 2007. Subsequently, the Company generated additional net operating losses and foreign tax credit carry forwards. It was determined in the fourth quarter of 2011 that due to the Internal Revenue Service’s Section 382 limitations on our ability to utilize the net operating losses and due to three years of cumulative losses, a full valuation allowance was warranted and as such, an expense was recorded. See Note 7 to the Consolidated Financial Statements included in this report for further details.

LIQUIDITY AND CAPITAL RESOURCES

AETI’s long-term debt as of December 31, 2012 was $0.5 million on which payments are current.

Notes Payable

The Company entered into a credit agreement with JP Morgan Chase Bank, N.A. (“Chase”) in October 2007. The credit agreement currently has a maturity on July 1, 2014. At December 31, 2012 and 2011, there were $0.5 million and $5.0 million of borrowings outstanding and at December 31, 2012, there was additional borrowing capacity of $6.9 million. The revolving credit line is $10.0 million with a limit of up to $6.0 million of borrowing in the event that “adjusted net income” is less than $1.00 for any quarter (“Line Limit”). Adjusted net income is defined as domestic operating income plus depreciation and amortization. The agreement is collateralized by the Company’s real estate in Houston and Beaumont, Texas, trade accounts receivable, equipment, inventories, and work-in-process, and the Company’s subsidiaries are guarantors of the borrowings. Under the agreement, the Company pays a commitment fee of 0.3% of the unused portion of the credit limit each quarter. Additionally, the terms of the agreement contain covenants which provide for customary restrictions and limitations, the maintenance of certain financial ratios,

including maintenance of a minimum current ratio, leverage ratio and tangible net worth and restriction from paying dividends without prior written consent of the bank. On July 27, 2012, the Company amended its interest rate on the Company borrowings to the LIBOR rate (0.3% at December 31, 2012) plus 3.25% per annum. Prior to July 27, 2012, the interest rate on the Company’s borrowings was 30 day LIBOR rate plus 2.75% per year. See Note 8 notes payable to the consolidate financial statement for more information on this facility.

Sources and Use of Cash

We derive the majority of our operating cash inflow from receipts on the sale of goods and services and cash outflow for the procurement of materials and labor. Accordingly, cash flow is subject to market fluctuations and conditions. A substantial portion of our business, primarily construction and products, is characterized by long-term contracts. Most of our long-term contracts allow for several progress billings that provide us with cash receipts as costs are incurred throughout the project, rather than upon contract completion, thereby reducing working capital requirements. We also utilize borrowings under our revolving credit agreement, discussed in the preceding section, for our cash needs.

Operating Activities

During the twelve months ended December 31, 2012, the Company used cash flows in operations of $0.8 million as compared to generating $1.1 million for the same period in 2011. In both periods, the impact on cash from the operating activities was benefited by the generation of cash from working capital of $1.4 million for the year ended December 31, 2012 and $2.4 million for the same period in 2011. The increase in cash generated from working capital is a result decreases in account receivables offset by increases in inventory, primarily in the TPS segment.

Investing Activities

During the twelve months ended December 31, 2012, the Company used $0.2 million in cash from investing activities compared to generating $0.5 million for the comparable period in 2011. This is mainly attributable to dividends received from joint ventures, amounting to $1.0 million in 2012 and $1.2 million in 2011 respectively. Capital expenditures in 2012 totaled $1,455,000 and $533,000 in 2011.

Financing Activities

During the twelve months ended December 31, 2012, the Company generated $103,000 in cash from financing activities as compared to $831,000 for the comparable period in 2011. The main source of cash was from the issuance of $5.0 million of preferred stock in 2012 which was offset by a $4.5 million paydown on the revolving credit facility. During 2011 the Company borrowed $1.0 million under the revolving credit facility to provide liquidity for operations.

Cash Flow

We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of debt requirements and operating cash needs. To meet our short and long-term liquidity requirements, we rely primarily on cash from operations. Beyond cash generated from operations, we have a credit facility of $10.0 million with $6.9 million available at December 31, 2012 and $4.5 million of unrestricted cash at December 31, 2012
