Overview

SigmaTron is a Delaware corporation, which was organized on November 16, 1993, and commenced operations when it became the successor to all of the assets and liabilities of SigmaTron L.P., an Illinois limited partnership, through a reorganization on February 8, 1994.

The Company operates in one business segment as an independent provider of electronic manufacturing services (“EMS”), which includes printed circuit board assemblies and completely assembled (box-build) electronic products. In connection with the production of assembled products, the Company also provides services to its customers, including (1) automatic and manual assembly and testing of products; (2) material sourcing and procurement; (3) manufacturing and test engineering support; (4) design services; (5) warehousing and distribution services; and (6) assistance in obtaining product approval from governmental and other regulatory bodies. The Company provides these manufacturing services through an international network of facilities located in the United States, Mexico, China, Vietnam and Taiwan.

The Company provides manufacturing and assembly services ranging from the assembly of individual components to the assembly and testing of box-build electronic products. The Company has the ability to

3

produce assemblies requiring mechanical as well as electronic capabilities. The products assembled by the Company are then incorporated into finished products sold in various industries, particularly appliance, consumer electronics, gaming, fitness, industrial electronics, medical/life sciences, semiconductor, telecommunications and automotive.

The Company operates manufacturing facilities in Elk Grove Village, Illinois; Union City, California; Acuna, Chihuahua and Tijuana, Mexico; Suzhou, China; and Ho Chi Minh City, Vietnam. In addition, the Company maintains materials sourcing offices in Elk Grove Village, Illinois; Union City, California; and Taipei, Taiwan and also has warehouses in Del Rio, Texas. The Company also provides design services at Carpentersville and Crystal Lake, Illinois. Effective May 2013, the Company combined both locations into a new building in Elgin, Illinois.

In an effort to facilitate the growth of our China operation, the Company established a new Chinese entity in October 2011 that allows the Company to provide services competitively to the domestic market in China. Nonetheless, in fiscal year 2012 and 2013, the Company continued to see a trend of Chinese costs increasing, thereby making Mexico a more competitive manufacturing location to service North America. Indications suggest that this trend will continue. We feel the Company’s international footprint provides our customers with flexibility within the Company to manufacture in China, Mexico or Vietnam. We believe this strategy has continued to serve the Company well during these difficult economic times as its customers continuously evaluate their supply chain strategies.

On May 31, 2012, SigmaTron acquired certain assets and assumed certain liabilities of Spitfire. Spitfire was a privately held Illinois corporation headquartered in Carpentersville, Illinois with captive manufacturing sites in Chihuahua, Mexico and Ho Chi Minh City, Vietnam. Both manufacturing sites were among the assets acquired by the Company. Spitfire was an original equipment manufacturer (“OEM”) of electronic controls, with a focus on the major appliance (white goods) industry. Although North America is currently its primary market, Spitfire has applications that can be used worldwide. The Company provided manufacturing solutions for Spitfire since 1994, and was a strategic partner to Spitfire as it developed its OEM electronic controls business.

Spitfire provides cost effective designs as control solutions for its customers, primarily in high volume applications of domestic cooking ranges, dishwashers, refrigerators, and portable appliances. The Company’s Spitfire division is a member of the Association of Home Appliance Manufacturers (“AHAM”), as well as other industry related trade associations and is ISO 9001:2008 certified. The Spitfire acquisition has enabled the Company to offer design services for the first time in specific markets.

Due to the acquisition of Spitfire, effective June 1, 2012, the Company discontinued selling to Spitfire and instead began selling directly to Spitfire’s former customers.

The Company expects continuing pressures on margins. The Company is hopeful to see a sustained recovery in the second half of calendar 2013. Until that time, the Company will continue to carefully manage its cost structure. The Company continues to add new customers and new programs with existing customers, some of which are not launching or transitioning as quickly as initially forecasted by the Company’s customers, but the Company believes they will eventually add to its revenue base. We continue to work on integrating Spitfire into SigmaTron, which we believe is proceeding on plan and has started to add to our menu of services that we can offer customers.

In addition, through its Spitfire Control division, the Company offers complete product design services for a variety of industries and applications, including appliance controls.

Supply Chain Management: The Company provides complete supply chain management for the procurement of components needed to build customers’ products. This includes the procurement and management of all types of electronic components and related mechanical parts such as plastics and metals. The Company’s resources supporting this activity are provided both on a plant specific basis as well as globally through its international procurement office (“IPO”) in Taipei, Taiwan. Each of its sites is linked together using the same Enterprise Resource Planning (“ERP”) system and custom IScore software tools with real-time on-line visibility for customer access. The Company procures material from virtually every major manufacturer and distributor of electronic parts in the world today.

Warehousing and Distribution: The Company provides in-house and third party warehousing, shipping, and customs brokerage for border crossings as part of its service offering. This includes international shipping, drop shipments to the end customer, as well as, support of inventory optimization activities such as kanban and consignment.

Green, Sustainability, and Social Responsible Initiatives: The Company supports initiatives that promote sustainability, green environment and social responsibility. The Company requires its supply chain to meet all government imposed requirements in these areas and helps its customers in achieving effective compliance. This includes, but is not limited to, Restrictions of Hazardous Substances (“RoHS”), Restriction of Chemicals (“Reach”) and Conflict Minerals regulations.

Manufacturing Location and Certifications: The Company’s manufacturing and warehousing locations are strategically located to support our customers with locations in Elk Grove Village, Illinois; Union City, California; Acuna, Chihuahua and Tijuana, Mexico; Del Rio, Texas; Suzhou, China and Ho Chi Minh City, Vietnam. The Company’s ability to transition manufacturing to lower cost regions without jeopardizing flexibility and service, differentiate it from the competition. Manufacturing certifications and registrations are location specific, and include ISO 9001:2008, ISO 14001:2004, medical ISO 13485:2003, Aerospace AS9100C and International Traffic in Arms Regulations (“ITAR”) certifications.

Markets and Customers

The Company’s customers are in the appliance, gaming, industrial electronics, fitness, medical/life sciences, semiconductor, telecommunications and consumer electronics industries. As of April 30, 2013, the Company had approximately 110 active customers ranging from Fortune 500 companies to small, privately held enterprises.

The following table shows, for the periods indicated, the percentage of net sales to the principal end-user markets it serves.

		Percent of Net Sales
Markets	Typical OEM Application	Fiscal 2013 %			Fiscal 2012 %
Industrial Electronics	Motor controls, power supplies, lighting products, scales, joysticks		36.9			40.4
Appliances	Household appliance controls		41.4			32.9
Fitness	Treadmills, exercise bikes, cross trainers		10.2			14.0
Semiconductor Equipment	Process control and yield management equipment for semiconductor productions		2.6			3.5
Gaming	Slot machines, lighting displays		2.5			3.2
Telecommunications	Routers, communication		1.8			2.7
Consumer Electronics	Battery backup sump pumps, electric bikes, personal grooming, computers		2.7			1.8
Medical/Life Sciences	Clinical diagnostic systems and instruments		1.9			1.5
Total			100	%		100	%

For the fiscal year ended April 30, 2013, Electrolux and Life Fitness, Inc. accounted for 26.8% and 9.6%, respectively, of the Company’s net sales. For the fiscal year ended April 30, 2012, Spitfire and Life Fitness, Inc., the Company’s largest two customers, accounted for 21.0% and 14.0%, respectively, of the Company’s net sales. As discussed above, on May 31, 2012, the Company acquired Spitfire. As of June 1, 2012, the Company discontinued selling to Spitfire and instead began selling to Spitfire’s former customers. Although the Company does not have a long term contract with Electrolux or Life Fitness, the Company expects that Electrolux and Life Fitness will continue to account for a significant percentage of the Company’s net sales, although the percentage of net sales may vary from period to period.

Sales and Marketing

The Company markets its services through 13 independent manufacturers’ representative organizations that together currently employ approximately 41 sales personnel in the United States and Canada. Independent manufacturers’ representatives organizations receive variable commissions based on orders received by the Company and are assigned specific accounts, not territories. Many of the members of the Company’s senior management are actively involved in sales and marketing efforts, and the Company has 6 direct sales employees.

Sales can be a misleading indicator of the Company’s financial performance. Sales levels can vary considerably among customers and products depending on the type of services (consignment versus turnkey) rendered by the Company and the demand by customers. Consignment orders require the Company to perform manufacturing services on components and other materials supplied by a customer, and the Company charges only for its labor, overhead and manufacturing costs, plus a profit. In the case of turnkey orders, the Company provides, in addition to manufacturing services, the components and other materials used in assembly. Turnkey contracts, in general, have a higher dollar volume of sales for each given assembly, owing to inclusion of the cost of components and other materials in net sales and cost of goods sold. Variations in the number of turnkey orders compared to consignment orders can lead to significant fluctuations in the Company’s revenue and gross margin levels. Consignment orders accounted for less than 5% of the Company’s revenues for each of the fiscal years ended April 30, 2013 and 2012.

6

In the past, the timing of production and delivery of orders, primarily at the direction of its customers, has caused the Company to experience significant quarterly fluctuations in its revenue and earnings, and the Company expects such fluctuations to continue.

Mexico, Vietnam and China Operations

The Company’s wholly-owned subsidiary, Standard Components de Mexico, S.A, a Mexican corporation, is located in Acuna, Coahuila Mexico, a border town across the Rio Grande River from Del Rio, Texas, and is 155 miles west of San Antonio. Standard Components de Mexico, S.A. was incorporated and commenced operation in 1968 and had 779 employees at April 30, 2013. The Company’s wholly-owned subsidiary, AbleMex S.A. de C.V., a Mexican corporation, is located in Tijuana, Baja California Mexico, a border town south of San Diego, California. AbleMex S.A. de C.V. was incorporated and commenced operations in 2000. The operation had 154 employees at April 30, 2013. The Company’s wholly-owned subsidiary, Digital Appliance Controls de Mexico S.A., a Mexican corporation, is located in Chihuahua, Mexico, located approximately 235 miles from El Paso, Texas. Digital Appliance Controls de Mexico S.A. was incorporated and commenced operations in 1997. The operation had 473 employees at April 30, 2013. The Company believes that one of the key benefits to having operations in Mexico is its access to cost-effective labor resources while having geographic proximity to the United States.

The Company’s wholly-owned foreign enterprises, Wujiang SigmaTron Electronics Co., Ltd. and SigmaTron Electronic Technology Co., Ltd., are located in Suzhou, China. The Company has entered into an agreement with governmental authorities in the economic development zone of Wujiang, Jiangsu Province, Peoples Republic of China, pursuant to which the Company became the lessee of a parcel of land of approximately 100 Chinese acres. The term of the land lease is 50 years. The Company built a manufacturing plant, office space and dormitories on this site during 2004. Both SigmaTron China entities operate at this site. At April 30, 2013, this operation had 406 employees.

The Company’s wholly-owned subsidiary, Spitfire Controls (Vietnam) Co. Ltd. is located in Amata Industrial Park, Bien Hoa City, Dong Nai Province, Vietnam, and is 18 miles east of Ho Chi Minh City. Spitfire Controls (Vietnam) Co. Ltd. was incorporated and commenced operation in 2005 and had 366 employees as of April 30, 2013.

The Company provides funds for salaries, wages, overhead and capital expenditure items as necessary to operate its wholly-owned Mexican, Vietnam and Chinese subsidiaries and the Taiwan IPO. The Company provides funding in U.S. dollars, which are exchanged for Pesos, Dong, Renminbi, and New Taiwan dollars as needed. The fluctuation of currencies from time to time, without an equal or greater increase in inflation, could have a material impact on the financial results of the Company. The impact of currency fluctuation for the fiscal year ended April 30, 2013 resulted in a foreign currency loss of approximately $359,000 representing a material change from the prior year’s foreign currency gain. In fiscal year 2013, the Company’s U.S. operations paid approximately $36,920,000 to its foreign subsidiaries for services provided. In fiscal year 2013, the Company’s wholly-owned trading company, SigmaTron International Trading Co. was liquidated. The Company received a distribution of approximately $180,000 as a result of this liquidation. In fiscal year 2012, the Company received a distribution of previously taxed earnings of approximately $1,039,000 from a foreign subsidiary based in Mexico. The Company did not incur any U.S. income taxes on the distribution as the earnings were previously subject to U.S. tax.

The Company has not recorded U.S. income taxes for a significant portion of undistributed earnings of the Company’s foreign subsidiaries, since these earnings have been, and under current plans will continue to be, permanently reinvested in these foreign subsidiaries. The cumulative amount of unremitted earnings for which U.S. income taxes have not been recorded is approximately $11,300,000.

The consolidated financial statements as of April 30, 2013 include the accounts and transactions of SigmaTron, its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls

(Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Wujiang SigmaTron Electronics Co., Ltd. and SigmaTron Electronic Technology Co., Ltd., and international procurement office, SigmaTron Taiwan Branch. The functional currency of the Mexican and Vietnam subsidiaries, Chinese foreign enterprise and Taiwanese procurement branch is the U.S. dollar. Intercompany transactions are eliminated in the consolidated financial statements.

Competition

The EMS industry is highly competitive and subject to rapid change. Furthermore, both large and small companies compete in the industry, and many have significantly greater financial resources, more extensive business experience and greater marketing and production capabilities than the Company. The significant competitive factors in this industry include price, quality, service, timeliness, reliability, the ability to source raw components, and manufacturing and technological capabilities. The Company believes it can competitively address all of these factors.

Consolidation

As a result of consolidation and other transactions involving competitors and other companies in the Company’s markets, the Company occasionally reviews potential transactions relating to its business, products and technologies. Such transactions could include mergers, acquisitions, strategic alliances, joint ventures, licensing agreements, co-promotion agreements, financing arrangements or other types of transactions. In the future, the Company may choose to enter into these types of or other transactions at any time depending on available sources of financing, and such transactions could have a material impact on the Company’s business, financial condition or operations.

On May 31, 2012, SigmaTron acquired certain assets and assumed certain liabilities of Spitfire. Spitfire was a privately held Illinois corporation with captive manufacturing sites in Chihuahua, Mexico and suburban Ho Chi Minh City, Vietnam. Both manufacturing sites were among the assets acquired by the Company. Spitfire was an OEM of electronic controls, with a focus on the major appliance (white goods) industry. Although North America was its primary market, Spitfire has applications that can be used worldwide. The Company provided manufacturing solutions for Spitfire since 1994, and was a strategic partner to Spitfire as it developed its OEM electronic controls business.

Governmental Regulations

The Company’s operations are subject to certain foreign, federal, state and local regulatory requirements relating to, among others, environmental, waste management, labor and health and safety matters. Management believes that the Company’s business is operated in material compliance with all such regulations. Effective mid-2006, the Company’s customers were required to comply with RoHS, directives for all of products that ship to the European marketplace. RoHS prohibits the use of lead, mercury and certain other specified substances in electronics products. The Company has RoHS-dedicated manufacturing capabilities at all of its manufacturing operations.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), introduced reporting requirements for verification of whether the Company directly (or indirectly through suppliers of components) is purchasing the minerals or metals gold, columbite-tantalite, cassiterite, wolframite and their derivatives: tin, tungsten, and tantalum that are being provided by sources in the conflict region of the Democratic Republic of Congo. The Company is working with its suppliers and customers to comply with the due diligence reporting requirements to comply with the Dodd-Frank Act.

To date, the Company’s costs of compliance and environmental remediation have not been material. However, additional or modified requirements may be imposed in the future. If such additional or modified requirements are imposed, or if conditions requiring remediation are found to exist, the Company may be required to incur additional expenditures.

8

Backlog

The Company relies on customers’ forecasted orders and purchase orders (firm orders) from its customers to estimate backlog. Historically customers rescheduled or cancelled firm orders and consequently there is little or no financial significance between forecasted orders or firm orders. The Company has eliminated the distinction in its accounting system between the two types of orders, and only estimates firm orders. The Company’s backlog of forecasted and firm orders as of April 30, 2013 and 2012 was approximately $119,300,000 and $89,600,000, respectively. The Company estimates its firm orders at April 30, 2013 and 2012 to be $84,600,000 and $57,100,000, respectively. The Company anticipates a significant portion of the backlog at April 30, 2013 will ship in fiscal year 2014. Because customers may cancel or reschedule deliveries, backlog may not be a meaningful indicator of future revenue. Variations in the magnitude and duration of contracts, forecasts and purchase orders received by the Company and delivery requirements generally may result in substantial fluctuations in backlog from period to period.

Employees

The Company employed approximately 2,700 people as of April 30, 2013, including 179 engaged in engineering or engineering-related services, 2,131 in manufacturing and 390 in administrative and marketing functions.

The Company has a labor contract with Production Workers Union Local No. 10, AFL-CIO, covering the Company’s workers in Elk Grove Village, Illinois which expires on November 30, 2015. The Company’s Mexican subsidiary, Standard Components de Mexico S.A., has a labor contract with Sindicato De Trabajadores de la Industra Electronica, Similares y Conexos del Estado de Coahuila, C.T.M. covering the Company’s workers in Acuna, Mexico which expires on February 1, 2014. The Company’s subsidiary located in Tijuana Mexico, has a labor contract with Sindicato Mexico Moderno De Trabajadores De La, Baja California, C.R.O.C. The contract does not have an expiration date. The Company’s subsidiary located in Ho Chi Minh City, Vietnam, has a labor contract with Labor Union of Dong Nai All Industrial Zones, Province of Dong Nai, Vietnam. The contract does not have an expiration date.

Since the time the Company commenced operations, it has not experienced any union-related work stoppages. The Company believes its relations with both unions and its other employees are good.

ITEM 1A. RISK FACTORS

The following risk factors should be read carefully in connection with evaluating our business and the forward-looking information contained in this Annual Report on Form 10-K. Any of the following risks could materially adversely affect our business, operations, industry or financial position or our future financial performance. While the Company believes it has identified and discussed below the key risk factors affecting its business, there may be additional risks and uncertainties that are not presently known or that are not currently believed to be significant that may adversely affect its business, operations, industry, financial position and financial performance in the future.

The Company’s ability to secure and maintain sufficient credit arrangements is key to its continued operations.

There is no assurance that the Company will be able to retain or renew its credit agreements and other finance agreements in the future. In the event the business grows rapidly, the uncertain economic climate continues or the Company considers another acquisition, additional financing resources could be necessary in the current or future fiscal years. There is no assurance that the Company will be able to obtain equity or debt financing at acceptable terms, or at all in the future.

The Company has a senior secured credit facility with Wells Fargo Bank, N.A. (“Wells Fargo”), with a credit limit up to $30 million and an initial term through September 30, 2013. The facility allows the Company to choose among interest rates at which it may borrow funds. The interest rate is the prime rate plus one half percent (effectively, 3.75% at April 30, 2013) or LIBOR plus two and three quarter percent (effectively, 3.0% at April 30, 2013), which is paid monthly. The credit facility is collateralized by

10

substantially all of the domestically located assets of the Company and requires the Company to be in compliance with several financial covenants. In conjunction with the Spitfire acquisition, two of the financial covenants required by terms of the Company’s senior secured credit facility were amended as of May 31, 2012. The Company was in violation of certain of its financial covenants at July 31, 2012 and received a waiver for the financial covenant violations. The Company renegotiated its financial covenants during the quarter ended October 31, 2012 with Wells Fargo and extended the credit facility through September 30, 2014. As of April 30, 2013, the Company again amended its credit agreement and renegotiated two of the financial covenants required by the terms of the Company’s senior secured credit facility. At April 30, 2013, the Company was in compliance with its amended financial covenants. As of April 30, 2013, there was an $18,500,000 outstanding balance and $11,500,000 of unused availability under the credit facility.

The Company anticipates its credit facilities, cash flow from operations and leasing resources will be adequate to meet its working capital requirements and capital expenditures for the next twelve months. There is no assurance that the Company will be able to retain or renew its credit agreements in the future, or that any retention or renewal will be on the same terms as currently exist. In the event the business grows rapidly, the current economic climate deteriorates, customers delay payments, or the Company considers an acquisition, additional financing resources could be necessary in the current or future fiscal years. There is no assurance that the Company will be able to obtain equity or debt financing at acceptable terms, or at all, in the future.

Adverse changes in the economy or political conditions could negatively impact the Company’s business, results of operations and financial condition.

The Company’s sales and gross margins depend significantly on market demand for its customers’ products. The uncertainty in the U.S. and international economic and political environment could result in a decline in demand for our customers’ products in any industry. Further, any adverse changes in tax rates and laws affecting our customers could result in decreasing gross margins. Any of these factors could negatively impact the Company’s business, results of operations and financial condition.

The Company experiences variable operating results.

The Company’s results of operations have varied and may continue to fluctuate significantly from period to period, including on a quarterly basis. Consequently, results of operations in any period should not be considered indicative of the results for any future period, and fluctuations in operating results may also result in fluctuations in the price of the Company’s common stock.

The Company’s quarterly and annual results may vary significantly depending on numerous factors, many of which are beyond the Company’s control. Some of these factors include:

• changes in sales mix to customers

• changes in availability and rising component costs

• volume of customer orders relative to capacity

• market demand and acceptance of our customers’ products

• price erosion within the EMS marketplace

• capital equipment requirements needed to remain technologically competitive

• volatility in the U.S. and international economic and financial markets

The Company’s customer base is concentrated.

Sales to the Company’s five largest customers accounted for 53% and 57% of net sales for the fiscal years ended April 30, 2013 and 2012, respectively. The Company’s two largest customers accounted for 26.8% and 9.6% of net sales for the fiscal year ended April 30, 2013 compared to 21.0% and 14.0% of net sales for the fiscal year ended April 30, 2012. Significant reduction in sales to any of the Company’s major customers or the loss of a major customer could have a material impact on the Company’s operations. If the Company cannot replace canceled or reduced orders, sales will decline, which could have a material impact on the results of operations. There can be no assurance that the Company will retain any or all of its large customers. This risk may be further complicated by pricing pressures and intense competition prevalent in our industry.

11

The Company has a significant amount of trade accounts receivable from some of its customers due to customer concentration. If any of the Company’s customers have financial difficulties, the Company could encounter delays or defaults in the payment of amounts owed. This could have a significant adverse impact on the Company’s results of operations and financial condition.

Most of the Company’s customers do not commit to long-term production schedules, which makes it difficult to schedule production and achieve maximum efficiency at the Company’s manufacturing facilities and to manage inventory levels.

The volume and timing of sales to the Company’s customers may vary due to:

• customers’ attempts to manage their inventory

• variation in demand for the Company’s customers’ products

• design changes, or

• acquisitions of or consolidation among customers

Many of the Company’s customers do not commit to firm production schedules. The Company’s inability to forecast the level of customer orders with certainty can make it difficult to schedule production and maximize utilization of manufacturing capacity and manage inventory levels. The Company could be required to increase or decrease staffing and more closely manage other expenses in order to meet the anticipated demand of its customers. Orders from the Company’s customers could be cancelled or delivery schedules could be deferred as a result of changes in our customers’ demand, thereby adversely affecting the Company’s results of operations, and resulting in higher inventory levels.

The Company and its customers may be unable to keep current with the industry’s technological changes.

The market for the Company’s manufacturing services is characterized by rapidly changing technology and continuing product development. The future success of the Company’s business will depend in large part upon its customers’ ability to maintain and enhance their technological capabilities, develop and market manufacturing services which meet changing customer needs and successfully anticipate or respond to technological changes in manufacturing processes on a cost-effective and timely basis.

Our customers have competitive challenges, including rapid technological changes, pricing pressure and decreasing demand from their customers, which could adversely affect their business and the Company’s.

Factors affecting the industries that utilize our customers’ products could negatively impact our customers and the Company. These factors include:

• increased competition among our customers and their competitors

• the inability of our customers to develop and market their products

• recessionary periods in our customers’ markets

• the potential that our customers’ products become obsolete

• our customers’ inability to react to rapidly changing technology

Any such factor or a combination of factors could negatively impact our customers’ need for or ability to pay for our products, which could, in turn, affect the Company’s results of operations.

Customer relationships with start-up companies present more risk.

A small portion of the Company’s current customer base is comprised of start-up companies. Customer relationships with start-up companies may present heightened risk due to the lack of product history. Slow market acceptance of their products could result in demand fluctuations causing inventory levels to rise. Further, the current economic environment could make it difficult for such emerging companies to obtain additional funding. This may result in additional credit risk including, but not limited to, the collection of trade account receivables and payment for their inventory. If the Company does not have adequate allowances recorded, the results of operations may be negatively affected.

12

The Company faces intense industry competition and downward pricing pressures.

The EMS industry is highly fragmented and characterized by intense competition. Many of the Company’s competitors have greater experience, as well as greater manufacturing, purchasing, marketing and financial resources than the Company.

Competition from existing or potential new competitors may have a material adverse impact on the Company’s business, financial condition or results of operations. The introduction of lower priced competitive products, significant price reductions by the Company’s competitors or significant pricing pressures from its customers could adversely affect the Company’s business, financial condition, and results of operations.

The Company has foreign operations that may pose additional risks.

The Company has substantial manufacturing operations in multiple countries. Therefore, the Company’s foreign businesses and results of operations are dependent upon numerous related factors, including the stability of the foreign economies, the political climate, relations with the United States, prevailing worker wages, the legal authority of the Company to own and operate its business in a foreign country, and the ability to identify, hire, train and retain qualified personnel and operating management in Mexico.

The Company obtains many of its materials and components through its IPO in Taipei, Taiwan. The Company’s access to these materials and components is dependent on the continued viability of its Asian suppliers.

Approximately 9% and 10% of the total consolidated assets of the Company are located in foreign jurisdictions outside the United States as of April 30, 2013 and 2012, respectively.

The Company may not achieve expected profitability from its acquisitions.

The Company acquired Spitfire Control in May 2012. Acquisitions involve significant financial and operating risks that could have a material adverse effect on the Company’s results of operations.

Acquisitions involve significant risks, which could have a material adverse effect on the Company including:

Financial risks, include (1) the payment of a purchase price that exceeds the future value that we may realize from the acquired operations and businesses; (2) an increase in the Company’s expenses and working capital requirements, which could reduce our return on invested capital; (3) potential known and unknown liabilities of the acquired businesses; (4) costs associated with integrating acquired operations and business; (5) the incurrence of additional debt; (6) the financial impact of incorrectly valuing goodwill and other intangible assets involved in any acquisitions, potential future impairment write-downs of goodwill and other intangible assets and the amortization of other intangible assets; (7) possible adverse tax and accounting effects; and (8) the risk that the Company will spend substantial amounts purchasing these manufacturing facilities and assume significant contractual and other obligations with no guaranteed levels of revenue or that the Company may have to close or sell acquired facilities at its costs, which may include substantial employee severance costs and asset write-offs, which may result, in our incurring significant losses.

The Company must implement its management information systems, operating systems and internal controls, and assimilate and manage the personnel of the acquired operations. The difficulties of this integration may be further complicated by geographic distances. The integration of acquired businesses may not be successful and could result in disruption to other parts of our business. To date the integration has proceeded as planned and completion is expected in the second fiscal quarter of 2014.

13

Disclosure and internal controls may not detect all errors or fraud.

The Company’s management, including the Chief Executive Officer and Chief Financial Officer, do not believe that the Company’s disclosure controls and internal controls will prevent all errors and all fraud. The Company’s disclosure controls and internal controls can provide only reasonable assurance that the procedures will meet the control objectives. Controls are limited in their effectiveness by human error, including faulty judgments in decision-making. Further, controls can be circumvented by collusion of two or more people or by management override of controls.

Inadequate internal control over financial reporting could result in a reduction in the value of our common stock.

If the Company identifies and reports a material weakness in its internal control over financial reporting, shareholders and the Company’s lenders could lose confidence in the reliability of the Company’s financial statements. This could have a material adverse impact on the value of the Company’s stock and the Company’s liquidity.

There is a risk of fluctuation of various currencies integral to the Company’s operations.

The Company purchases some of its material components and funds some of its operations in foreign currencies. From time to time the currencies fluctuate against the U.S. dollar. Such fluctuations could have a measurable impact on the Company’s results of operations and performance. The impact of currency fluctuation for the year ended April 30, 2013 resulted in a currency loss of approximately $359,000 representing a material change from the prior year’s foreign currency gain. These fluctuations are expected to continue and could have a negative impact on the Company’s results of operations. The Company did not, and is not expected to, utilize derivatives or hedge foreign currencies to reduce the risk of such fluctuations.

The availability of raw components or an increase in their price may affect the Company’s operations and profits.

The Company relies on numerous third-party suppliers for components used in the Company’s production process. Certain of these components are available only from single-sources or a limited number of suppliers. In addition, a customer’s specifications may require the Company to obtain components from a single-source or a small number of suppliers. The loss of any such suppliers could have a material impact on the Company’s results of operations. Further, the Company could operate at a cost disadvantage compared to competitors who have greater direct buying power from suppliers. The Company does not enter into long-term purchase agreements with major or single-source suppliers. The Company believes that short-term purchase orders with its suppliers provides flexibility, given that the Company’s orders are based on the changing needs of its customers.

The Company depends on management and skilled personnel.

The Company depends significantly on its President/CEO and other executive officers. The Company’s employees generally are not bound by employment agreements and the Company cannot assure that it will retain its executive officers or skilled personnel. The loss of the services of any of these key employees could have a material impact on the Company’s business and results of operations. In addition, despite significant competition, continued growth and expansion of the Company’s EMS business will require that the Company attract, motivate and retain additional skilled and experienced personnel. The inability to satisfy such requirements could have a negative impact on the Company’s ability to remain competitive in the future.

Favorable labor relations are important to the Company.

The Company currently has labor union contracts with its employees constituting approximately 43% of its workforce. Although the Company believes its labor relations are good, any labor disruptions, whether union-related or otherwise, could significantly impair the Company’s business, substantially increase the Company’s costs or otherwise have a material impact on the Company’s results of operations.

14

Failure to comply with environmental regulations could subject the Company to liability.

The Company is subject to a variety of environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during its manufacturing process. To date, the cost to the Company of such compliance has not had a material impact on the Company’s business, financial condition or results of operations. However, there can be no assurance that violations will not occur in the future as a result of human error, equipment failure or other causes. Further, the Company cannot predict the nature, scope or effect of environmental 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 the Company and could have a material impact on the Company’s business, financial condition and results of operations. Any failure by the Company to comply with present or future regulations could subject it to future liabilities or the suspension of production which could have a material negative impact on the Company’s results of operations.

Compliance with government regulations regarding the use of conflict minerals may result in increased cost and risk to the Company.

As part of the Dodd-Frank Act, the Securities and Exchange Commission (“SEC”) has issued disclosure requirements regarding the use of certain minerals mined from the Democratic Republic of Congo, known as conflict minerals. The Disclosure for the Company is required in May 2014. The Company could incur significant costs related to implementing a procedure that will meet the requirements of the Dodd-Frank Act. The Company’s material sourcing is broad-based and uses many suppliers. As a result, the Company may not be able to verify the origins of the minerals used in components it purchases and uses in products it sells. Customers may demand that the products they purchase be free of conflict minerals and implementation of this requirement could affect the sourcing and availability of components the Company purchases from its suppliers. This could reduce the number of suppliers that provide conflict mineral-free components. The Company may not be able to obtain components in sufficient quantities to meet customer demand or at a competitive price.

The price of the Company’s stock is volatile.

The price of the Company’s common stock historically has experienced significant volatility due to fluctuations in the Company’s revenue and earnings, other factors relating to the Company’s operations, the market’s changing expectations for the Company’s growth, overall equity market conditions and other factors unrelated to the Company’s operations. In addition, the limited float of the Company’s common stock and the limited number of market makers also affect the volatility of the Company’s common stock. Such fluctuations are expected to continue in the future.

An adverse change in the interest rates for our borrowings could adversely affect our results of operations.

The Company pays interest on outstanding borrowings under its senior secured credit facility and certain other long-term debt obligations at interest rates that fluctuate. An adverse change in the Company’s interest rates could have a material adverse effect on its results of operations.

Changes in securities laws and regulations may increase costs.

The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and listing requirements subsequently adopted by Nasdaq in response to Sarbanes-Oxley, have required changes in corporate governance practices, internal control policies and securities disclosure and compliance practices of public companies. More recently the Dodd-Frank Act requires changes to our corporate governance, compliance practices and securities disclosures. Compliance following the implementation of these rules has increased our legal and financial accounting costs. The Company expects increased costs related to these new regulations to continue, including, but not limited to, legal, financial and accounting costs. These developments may result in the Company having difficulty in attracting and retaining qualified members of the board or qualified officers. Further, the costs associated with the compliance with and implementation of procedures under these laws and related rules could have a material impact on the Company’s results of operations.

Overview

The Company operates in one business segment as an independent provider of EMS, which includes printed circuit board assemblies and completely assembled (box-build) electronic products. In connection with the production of assembled products, the Company also provides services to its customers, including (1) automatic and manual assembly and testing of products; (2) material sourcing and procurement; (3) manufacturing and test engineering support; (4) design services; (5) warehousing and distribution services; and (6) assistance in obtaining product approval from governmental and other regulatory bodies. The Company provides these manufacturing services through an international network of facilities located in the United States, Mexico, China, Vietnam and Taiwan.

On May 31, 2012, SigmaTron acquired certain assets and assumed certain liabilities of Spitfire. Spitfire was a privately held Illinois corporation with captive manufacturing sites in Chihuahua, Mexico and suburban Ho Chi Minh City, Vietnam. Both manufacturing sites were among the assets acquired by the Company. Spitfire was an original equipment manufacturer of electronic controls, with a focus on the major appliance (white goods) industry. Although North America is currently its primary market, Spitfire has applications that can be used worldwide. The Company provided manufacturing solutions for Spitfire since 1994, and was a strategic partner to Spitfire as it developed its OEM electronic controls business.

The Company’s Spitfire division provides cost effective designs as control solutions for its customers, primarily in high volume applications of domestic cooking ranges, dishwashers, refrigerators, and portable appliances. It is a member of the Association of Home Appliance Manufacturers (“AHAM”), as well as other industry related trade associations and is ISO 9001:2008 certified. The acquisition has enabled the Company to offer design services for the first time in specific markets.

The Company relies on numerous third-party suppliers for components used in the Company’s production process. Certain of these components are available only from single-sources or a limited number of suppliers. In addition, a customer’s specifications may require the Company to obtain components from a single-source or a small number of suppliers. The loss of any such suppliers could have a material impact on the Company’s results of operations. Further, the Company could operate at a cost disadvantage compared to competitors who have greater direct buying power from suppliers. The Company does not enter into long-term purchase agreements with major or single-source suppliers. The Company believes that short-term purchase orders with its suppliers provides flexibility, given that the Company’s orders are based on the changing needs of its customers.

Sales can be a misleading indicator of the Company’s financial performance. Sales levels can vary considerably among customers and products depending on the type of services (consignment versus turnkey) rendered by the Company and the demand by customers. Consignment orders require the Company to perform manufacturing services on components and other materials supplied by a customer, and the Company charges only for its labor, overhead and manufacturing costs, plus a profit. In the case of turnkey orders, the Company provides, in addition to manufacturing services, the components and other materials used in assembly. Turnkey contracts, in general, have a higher dollar volume of sales for each given assembly, owing to inclusion of the cost of components and other materials in net sales and cost of goods sold. Variations in the number of turnkey orders compared to consignment orders can lead to significant fluctuations in the Company’s revenue and gross margin levels. Consignment orders accounted for less than 5% of the Company’s revenues for the year ended April 30, 2013.

In an effort to facilitate growth of our China operation, the Company established a new Chinese entity in October 2011 that allows the Company to provide services competitively to the domestic market in China. Nonetheless, in fiscal year 2012 and 2013, the Company continued to see a trend of Chinese costs increasing, thereby making Mexico a more competitive manufacturing location to service North America. Indications suggest that this trend will continue. We feel the Company’s international footprint provides our customers with flexibility within the Company to manufacture in China, Mexico or Vietnam. We believe this strategy has continued to serve the Company well during these difficult economic times as its customers continuously evaluate their supply chain strategies.

19

In the past, the timing of production and delivery of orders, primarily at the direction of its customers, has caused the Company to experience significant quarterly fluctuations in its revenues and earnings. The Company continued to experience pricing pressures from both its customer and suppliers. The Company expects continuing pressure on margins until the economy achieves a sustained recovery. The Company is hopeful to see that start the second half of calendar 2013. Until that time, the Company will continue to carefully manage its cost structure. The Company continues to add new customers and new programs with existing customers. Some are not launching or transitioning as quickly as initially forecasted by the Company’s customers, but the Company believes they will eventually add to its revenue base. We continue to work on integrating Spitfire into SigmaTron, which the Company believes is proceeding on plan and has started to add to our menu of services that we can offer customers.

Due to the acquisition of Spitfire, effective June 1, 2012, the Company discontinued selling to Spitfire and instead began selling directly to Spitfires’ customers.

On May 8, 2012, the Company entered into a real estate lease agreement to relocate its Tijuana, Mexico operation to a new facility within Tijuana, Mexico. The relocation was completed in July 2012. As of April 30, 2013, the Company has incurred approximately $424,000 in relocation expenses as a result of the move as of April 30, 2013. All incentives realized under the lease will be recognized over the term of the lease, which is five years.

Critical Accounting Policies:

Management Estimates and Uncertainties - The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

Revenue Recognition - Revenues from sales of the Company’s electronic manufacturing services business are recognized when the finished good product is shipped to the customer. In general, and except for consignment inventory, it is the Company’s policy to recognize revenue and related costs when the finished goods have been shipped from its facilities, which is also the same point that title passes under the terms of the purchase order. Finished goods inventory for certain customers is shipped from the Company to an independent warehouse for storage or shipped directly to the customer and stored in a segregated part of the customer’s own facility. Upon the customer’s request for finished goods inventory, the inventory is shipped to the customer if the inventory was stored off-site, or transferred from the segregated part of the customer’s facility for consumption or use by the customer. The Company recognizes revenue upon such shipment or transfer. The Company does not earn a fee for such arrangements. The Company from time to time may ship finished goods from its facilities, which is also the same point that title passes under the terms of the purchase order, and invoice the customer at the end of the calendar month. This is done only in special circumstances to accommodate a specific customer. Further, from time to time customers request the Company hold finished goods after they have been invoiced to consolidate finished goods for shipping purposes. The Company generally provides a 90 day warranty for workmanship only and does not have any installation, acceptance or sales incentives (although the Company has negotiated longer warranty terms in certain instances). The Company assembles and tests assemblies based on customers’ specifications. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties.

Inventories - Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out method. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or market. The Company establishes inventory reserves for valuation, shrinkage, and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of products sold. The Company records provisions for excess and obsolete inventories for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Actual product demand or market conditions could be different than that projected by management.

Goodwill - Goodwill represents the purchase price in excess of the fair value of assets acquired in business combinations. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 350, “Goodwill and other Intangible Assets,” requires the Company to assess goodwill and other indefinite-lived intangible assets for impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. The Company is permitted the option to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the fair value of any reporting unit is less than its corresponding carrying value. If, after assessing the totality of events and circumstances, the Company concludes that it is not more likely than not that the fair value of any reporting unit is less than its corresponding carrying value then the Company is not required to take further action. However, if the Company concludes otherwise, then it is required to perform a quantitative impairment test, including computing the fair value of the reporting unit and comparing that value to its carrying value. If the fair value is less than its carrying value, a second step of the test is required to determine if recorded goodwill is impaired. The Company also has the option to bypass the qualitative assessment for goodwill in any period and proceed directly to performing the quantitative impairment test. The Company will be able to resume performing the qualitative assessment in any subsequent period. The Company performed its annual goodwill impairment test as of February 1, 2013 and determined no impairment existed as of the date of the impairment test.

Impairment of Long-Lived Assets - The Company reviews long-lived assets, including amortizable intangible assets for impairment. Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company’s impairment review is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. The Company conducts annual reviews for idle and underutilized equipment, and review business plans for possible impairment. Impairment occurs when the carrying value of the assets exceeds the future undiscounted cash flows expected to be earned by the use of the asset group. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

Income Tax - The Company’s income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in both the U.S. and several foreign jurisdictions. Significant judgments and estimates by management are required in determining the consolidated income tax expense assessment.

Deferred income taxes arise from temporary differences between the tax and financial statement recognition of revenue and expense and tax credit carryforwards. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, the Company begins with historical results adjusted for the results of discontinued operations and changes in accounting policies, and incorporates assumptions including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment and estimates by management about the forecasts of future taxable income and are consistent with the plans and estimates the Company uses to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considers three years of cumulative operating income and/or loss.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position.

21

A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits.

The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined.

New Accounting Standards:

There are no recent accounting standards that had, or are expected to have, a significant effect on the Company’s consolidated financial statements.

Results of Operations:

FISCAL YEAR ENDED APRIL 30, 2013 COMPARED

TO FISCAL YEAR ENDED APRIL 30, 2012

The following table sets forth the percentage relationships of expense items to net sales for the years indicated:

	Fiscal Years
	2013			2012
Net sales		100.0	%		100.0	%
Operating expenses:
Cost of products sold		90.0			90.3
Selling and administrative expenses		9.3			8.0
Total operating expenses		99.3			98.3
Operating income		0.7	%		1.7	%

Fiscal Year 2013:

Net sales increased 26.7% to $198,439,534 in fiscal year 2013 from $156,635,984 in the prior year. The Company’s sales increased in fiscal year 2013 in industrial and consumer electronics, appliance and medical/life sciences marketplaces as compared to the prior year. The increase in sales dollars for these marketplaces was partially offset by a decrease in sales dollars in the fitness, gaming, telecommunications and semiconductor marketplaces. The increase in net sales for the fiscal year 2013 is a result of sales to customers due to the Spitfire acquisition, as well as our existing customers’ increased demand for product.

The Company’s sales in a particular industry are driven by the fluctuating forecasts and end-market demand of the customers within that industry. Sales to customers are subject to variations from period to period depending on customer order cancellations, the life cycle of customer products and product transition. Sales to the Company’s five largest customers accounted for 53% and 57% of net sales for fiscal years 2013 and 2012, respectively.

Gross profit increased to $19,925,646, or 10.0% of net sales, in fiscal year 2013 compared to $15,254,541, or 9.7% of net sales, in the prior fiscal year. The increase in gross profit for fiscal year 2013 was primarily the result of gross profits earned on sales to customers due to the Spitfire acquisition, as well as increased sales revenue from our existing customers. The Company has carefully managed its cost structure and has begun to achieve economies of scale integrating Spitfire into SigmaTron. The increase in gross profit

22

in fiscal year 2013 was partially offset by relocation expenses of approximately $399,000 for the Tijuana, Mexico move, and a foreign currency loss of $359,149 compared to a foreign currency gain of $133,979 in the prior fiscal year.

Selling and administrative expenses increased in fiscal year 2013 to $18,358,354, or 9.3% of net sales, compared to $12,611,673, or 8.0% of net sales, in fiscal year 2012 or an increase of $5,746,681. Of the increase noted above, for the fiscal year ended April 30, 2013, $4,469,106 was attributable to salaries and other administrative expenses for the Spitfire operations and $803,006 was transaction costs for the Spitfire Transaction. Other increases in selling and administrative expenses for the fiscal year ended April 30, 2013, were due to increases in commissions, freight out, computer maintenance, insurance and amortization expense. The increase in the foregoing selling and administrative expenses were partially offset by a decrease in bonus expense, depreciation and paper and supply expenses.

Interest expense decreased to $832,126 in fiscal year 2013 compared to $1,025,325 in fiscal year 2012. The interest expense decreased primarily due to the decreased borrowings under the Company’s banking arrangements and capital lease obligations. Interest expense for fiscal year 2014 may increase if interest rates or borrowings, or both, increase during fiscal year 2014.

In fiscal year 2013, income tax expense was $321,363 compared to $522,171 in income tax expense in fiscal year 2012. The effective tax rate for the years ended April 30, 2013 and 2012 was 39.5% and 31.5%, respectively. The increase in the effective tax rate for the year ended April 30, 2013 is due to the tax impact of additional profit from the Company’s U.S. entities and a dividend payment from its wholly-owned trading company, SigmaTron International Trading Co.

The Company reported net income of $492,961 in fiscal year 2013 compared to a net income of $1,134,324 for fiscal year 2012. Basic and diluted earnings per share for fiscal year 2013 were $0.13 and $0.12, respectively, compared to basic and diluted earnings per share of $0.29 for the year ended April 30, 2012.

Liquidity and Capital Resources:

Operating Activities.

Cash flow provided by operating activities was $3,751,631 for the fiscal year ended April 30, 2013, compared to cash flow provided by operating activities of $9,808,310 for the prior fiscal year. Cash flow provided by operating activities was the result of net income, the non-cash effects of depreciation and amortization, stock-based compensation expense, an increase in trade accounts payable and deferred rent expenses. The increase in accounts payable was due to timing of payments in the ordinary course of business. Net cash provided by operations in fiscal year 2013 was partially offset by an increase of inventories of $5,615,748 and accounts receivable of $5,242,863, primarily related to additional sales volume resulting from the Spitfire acquisition.

Cash flow provided by operating activities was $9,808,310 for the fiscal year ended April 30, 2012. Cash flow provided by operating activities in fiscal year 2012 was primarily the result of net income, the non-cash effects of depreciation and amortization, a decrease in inventory and an increase in accounts payable. The decrease in inventory of $7,147,110 was the result of the improvement of inventory management practices. The increase in accounts payable of $1,402,892 was due to timing of payments in the ordinary course of business. Net cash provided by operations in fiscal year 2012 was partially offset by an increase in accounts receivable. The increase in accounts receivable of $4,381,326 was due to increased sales volume and timing of cash receipts from a significant customer.

Investing Activities.

In fiscal year 2013, the Company purchased approximately $7,200,000 in machinery and equipment to be used in the ordinary course of business. The Company anticipates that it will make additional machinery and equipment purchases in fiscal year 2014 of approximately $13,500,000 to support its anticipated growth. The Company anticipates the purchases will be funded by lease transactions and its bank line of credit. The Company received approximately $1,142,000 in cash in conjunction with the Spitfire purchase. In addition, the Company received $22,000 in cash for proceeds related to the sale of machinery and equipment.

23

In fiscal year 2012, the Company purchased approximately $2,300,000 in machinery and equipment used in the ordinary course of business.

Financing Activities.

Cash provided by financing activities was $2,193,615 for the fiscal year ended April 30, 2013, compared to cash used in financing activities of $6,970,338 in fiscal year 2012. Cash provided by financing activities in fiscal year 2013 was primarily the result of increased borrowings of $2,500,000 under the credit facility. The additional borrowings were required to support the purchases of machinery and equipment and the increases in both accounts receivable and inventory.

Cash used in financing activities in fiscal year 2012 was primarily the result of $6,900,000 in payments under the credit facility and for capital lease obligations.

Financing Summary.

The Company has a senior secured credit facility with Wells Fargo with a credit limit up to $30 million and an initial term through September 30, 2013. The facility allows the Company to choose among interest rates at which it may borrow funds. The interest rate is the prime rate plus one half percent (effectively, 3.75% at April 30, 2013) or LIBOR plus two and three quarter percent (effectively, 3.0% at April 30, 2013), which is paid monthly. The credit facility is collateralized by substantially all of the domestically located assets of the Company and requires the Company to be in compliance with several financial covenants. In conjunction with the Spitfire acquisition, two of the financial covenants required by terms of the Company’s senior secured credit facility were amended as of May 31, 2012. The Company was in violation of certain of its financial covenants at July 31, 2012 and received a waiver for the financial covenant violations. The Company renegotiated its financial covenants during the quarter ended October 31, 2012 with Wells Fargo and extended the credit facility through September 30, 2014. As of April 30, 2013, the Company again amended its credit agreement and renegotiated two of the financial covenants required by the terms of the Company’s senior secured credit facility. At April 30, 2013, the Company was in compliance with its amended financial covenants. As of April 30, 2013, there was an $18,500,000 outstanding balance and $11,500,000 of unused availability under the credit facility.

The Company entered into a mortgage agreement on January 8, 2010, in the amount of $2,500,000, with Wells Fargo to refinance the property that serves as the Company’s corporate headquarters and its Illinois manufacturing facility. The Company repaid the prior Bank of America mortgage, which equaled $2,565,413, as of January 8, 2010, using proceeds from the Wells Fargo mortgage and senior secured credit facility. The Wells Fargo note bears interest at a fixed rate of 6.42% per year and is amortized over a sixty month period. A final payment of approximately $2,000,000 is due on or before January 8, 2015. The outstanding balance as of April 30, 2013 was $2,175,013.

On January 19, 2010, the Company entered into a leasing transaction with Wells Fargo Equipment Finance, Inc. to refinance $1,287,407 of equipment. The term of the lease financing agreement extended to January 18, 2012 with monthly payments of $55,872 and a fixed interest rate of 4.29%. This lease financing arrangement was paid in full as of January 31, 2012. The net book value of the equipment was $1,210,226 at April 30, 2013.

On August 20, 2010 and October 26, 2010, the Company entered into two capital leasing transactions (a lease finance agreement and a sale leaseback agreement) with Wells Fargo Equipment Finance, Inc., to purchase equipment totaling $1,150,582. The term of the lease finance agreement, with an initial principal amount of $315,252, extends to September 2016 with monthly payments of $4,973 and a fixed interest rate of 4.28%. The term of the sale leaseback agreement, with an initial principal payment amount of $835,330, extends to August 2016 with monthly payments of $13,207 and a fixed interest rate of 4.36%. At April 30, 2013, $188,955 and $478,417 was outstanding under the lease finance and sale leaseback agreements, respectively. The net book value at April 30, 2013 of the equipment under each of the lease finance agreement and sale leaseback agreement was $247,385 and $626,791, respectively.

24

On November 29, 2010, the Company entered into a capital lease with Wells Fargo Equipment Finance, Inc., to purchase equipment totaling $226,216. The term of the lease agreement extends to October 2016 with monthly payments of $3,627 and a fixed interest rate of 4.99%. At April 30, 2013, the balance outstanding under the capital lease agreement was $139,510. The net book value of the equipment under this lease at April 30, 2013 was $178,379.

The total amount outstanding at April 30, 2013 for the three remaining equipment lease transactions discussed above was $806,882. The Company had two other capital leases not discussed above, one of which was paid in full in August 2011 and the other was paid in full in November 2011. The total net book value of the equipment under these other leases at April 30, 2013 was $475,979.

In September 2010, the Company entered into a real estate lease agreement in Union City, CA, to rent 116,993 square feet of manufacturing and office space. Under the terms of the lease agreement, the Company receives incentives over the life of the lease, which extends through March 2021. The amount of the deferred rent income recorded for fiscal year 2013 was $2,140. In addition, the landlord provided the Company tenant incentives of $418,000, which are being amortized over the life of the lease.

On May 2012, the Company entered into a lease agreement in Tijuana, MX, to rent 112,000 square feet of manufacturing and office space. Under the terms of the lease agreement, the Company receives incentives over the life of the lease, which extends through November 2018. The amount of the deferred rent expense recorded for fiscal year 2013 was $362,796.

On May 31, 2012, the Company completed the acquisition of Spitfire, an OEM of electronic controls, with a focus on the major appliance industry. The acquisition added two manufacturing operations in locations that augment the Company’s footprint and add Spitfire’s design capabilities which allows the Company to offer design service for the first time in specific markets. In conjunction with the Spitfire acquisition, the Company recorded goodwill and other intangible assets of $3,222,899 and $6,142,000, respectively.

The Company provides funds for salaries, wages, overhead and capital expenditure items as necessary to operate its wholly-owned Mexican, Vietnam and Chinese subsidiaries and the Taiwan international procurement office. The Company provides funding, as needed, in U.S. dollars, which are exchanged for Pesos, Dong, Renminbi, and New Taiwan dollars as applicable. The fluctuation of currencies from time to time, without an equal or greater increase in inflation, could have a material impact on the financial results of the Company. The impact of currency fluctuation for the fiscal year ended April 30, 2013 resulted in a foreign currency loss of approximately $359,000. In fiscal year 2013, the Company’s U.S. operations paid approximately $36,920,000 to its foreign subsidiaries for services provided. In fiscal year 2013, the Company’s wholly-owned trading company, SigmaTron International Trading Co., was liquidated. The Company received a distribution of approximately $180,000 as a result of this liquidation. In fiscal year 2012, the Company received a distribution of previously paid taxed earnings of approximately $1,039,000 from a foreign subsidiary based in Mexico. The Company did not incur any U.S. income taxes on the distribution as the earnings were previously subject to U.S. tax.

The Company has not recorded U.S. income taxes for a significant portion of undistributed earnings of the Company’s foreign subsidiaries, since these earnings have been, and under current plans will continue to be, permanently reinvested in these foreign subsidiaries. The cumulative amount of unremitted earnings for which U.S. income taxes have not been recorded is approximately $11,300,000.

The Company anticipates that its credit facilities, cash flow from operations and leasing resources will be adequate to meet its working capital requirements and capital expenditures for the next twelve months. There is no assurance that the Company will be able to retain or renew its credit agreements in the future, or that any retention or renewal will be on the same terms as currently exist. In the event the business grows rapidly, the current economic climate deteriorates, customers delay payments, or the Company considers an acquisition, additional financing resources could be necessary in the current or future fiscal years. There is no assurance that the Company will be able to obtain equity or debt financing at acceptable terms, or at all, in the future.

25

The impact of inflation on the Company’s net sales, revenues and incomes from continuing operations for the past two fiscal years has been minimal.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

SigmaTron International, Inc.

Elk Grove Village, Illinois

We have audited the accompanying consolidated balance sheets of SigmaTron International, Inc. as of April 30, 2013 and 2012 and the related consolidated statements of income, changes in stockholders’ equity and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 SigmaTron International, Inc. at April 30, 2013 and 2012 and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2013 and 2012

NOTE A - DESCRIPTION OF THE BUSINESS

SigmaTron International, Inc., its subsidiaries, foreign enterprises and international procurement office (collectively, the “Company”) operates in one business segment as an independent provider of electronic manufacturing services (“EMS”), which includes printed circuit board assemblies and completely assembled (box-build) electronic products. In connection with the production of assembled products, the Company also provides services to its customers, including (1) automatic and manual assembly and testing of products; (2) material sourcing and procurement; (3) manufacturing and test engineering support; (4) design services; (5) warehousing and distribution services; and (6) assistance in obtaining product approval from governmental and other regulatory bodies. As of April 30, 2013, the Company provided these manufacturing services through an international network of facilities located in the United States, Mexico, China, Vietnam and Taiwan. Approximately 9% and 10% of the total consolidated assets of the Company are located in foreign jurisdictions outside the United States as of April 30, 2013 and 2012, respectively.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The consolidated financial statements include the accounts and transactions of SigmaTron International, Inc. (“SigmaTron”), its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls (Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Suzhou SigmaTron Electronics Co. Ltd., and SigmaTron Electronic Technology Co., Ltd. (collectively, “SigmaTron China”), and its international procurement office, SigmaTron Taiwan. The functional currency of the Mexican, Vietnamese and Chinese subsidiaries and procurement branch is the U.S. dollar. Intercompany transactions are eliminated in the consolidated financial statements. The impact of currency fluctuation for the fiscal year ended April 30, 2013 resulted in a loss of approximately $359,000, compared to a gain of approximately $134,000 for the prior fiscal year.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant

SigmaTron International, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

April 30, 2013 and 2012

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Use of Estimates - Continued

estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash and all highly liquid short-term investments maturing within three months of the purchase date.

Accounts Receivable

The majority of the Company’s accounts receivable are due from companies in the consumer electronics, gaming, fitness, industrial electronics, medical/life sciences, semiconductor, telecommunications and appliance industries. Credit is extended based on evaluation of a customer’s financial condition, and, generally, collateral is not required. Accounts receivable are due in accordance with agreed upon terms, and are stated at amounts due from customers net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payments terms are considered past due. The Company writes off accounts receivable when they are determined to be uncollectible.

Allowance for Doubtful Accounts

The Company’s allowance for doubtful accounts relates to receivables not expected to be collected from its customers. This allowance is based on management’s assessment of specific customer balances, considering the age of receivables and financial stability of the customer and a five year average of prior uncollectible amounts. If there is an adverse change in the financial condition of the Company’s customers, or if actual defaults are higher than provided for, an addition to the allowance may be necessary.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out method. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or market. The Company establishes inventory reserves for valuation, shrinkage, and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Inventories - Continued

products sold. The Company records provisions for excess and obsolete inventories for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Actual product demand or market conditions could be different than that projected by management.

Property, Machinery and Equipment

Property, machinery and equipment are valued at cost. The Company provides for depreciation and amortization using the straight-line method over the estimated useful life of the assets:

Buildings	20 years
Machinery and equipment	5-12 years
Office equipment and software	3-5 years
Tools and dies	12 months
Leasehold improvements	term of lease

Expenses for repairs and maintenance are charged to selling and administrative expenses as incurred.

Deferred Financing Costs

Deferred financing costs consist of costs incurred to obtain the Company’s long-term debt and are amortized using the straight-line method over the term of the related debt. Deferred financing fees of $70,776 and $8,756, net of accumulated amortization of $270,983 and $238,354 as of April 30, 2013 and 2012, respectively, are classified in other long-term assets on the Company’s balance sheet.

Income Taxes

Deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred income tax assets to an amount more likely than not to be realized.

SigmaTron International, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

April 30, 2013 and 2012

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Income Taxes - Continued

A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits.

The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increase or decreases to income tax expense in the period in which they are determined.

Earnings per Share

Basic earnings per share are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common stock equivalents such as stock options and restricted stock, had been exercised or vested. At April 30, 2013 and 2012, there were 400,190 anti-dilutive common stock equivalents, which have been excluded from the calculation of diluted earnings per share.

Revenue Recognition

Revenues from sales of the Companys’ electronic manufacturing services business are recognized when the finished good product is shipped to the customer. In general, and except for consignment inventory, it is the Companys’ policy to recognize revenue and related costs when the finished goods have been shipped from our facilities, which is also the same point that title passes under the terms of the purchase order. Finished goods inventory for certain customers is shipped from the Company to an independent warehouse for storage or shipped directly to the customer and stored in a segregated part of the customer’s own facility. Upon the customer’s request for finished goods inventory, the inventory is shipped to the customer if the inventory was stored off-site, or transferred from the segregated part of the customer’s facility for consumption or use by the customer. The Company recognizes revenue upon such shipment or transfer. The Company does not earn a fee for such arrangements. The Company from time to time may ship finished goods from its facilities, which is also the same point that title passes under the terms of the purchase order, and invoice the customer at the end of the calendar month. This is done only in special circumstances to accommodate a specific customer. Further, from

time to time customers request the Company hold finished goods after they have been invoiced to consolidate finished goods for shipping purposes. The Company generally provides a 90 day warranty for workmanship only and does not have any installation, acceptance or sales incentives (although the Company has negotiated longer warranty terms in certain instances). The Company assembles and tests assemblies based on customers’ specifications. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties.

Shipping and Handling Costs

The Company records shipping and handling costs as selling and administrative expenses. Customers are typically invoiced for shipping costs. Shipping and handling costs were not material to the financial statements for fiscal years 2013 or 2012.

Fair Value Measurements

Fair value measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. The Company utilizes a fair value hierarchy based upon the observability of inputs used in valuation techniques as follows:

Level 1:	Observable inputs such as quoted prices in active markets;
Level 2:	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
Level 3:	Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, receivables, accounts payable and accrued expenses which approximate fair value at April 30, 2013, due to their short-term nature. The carrying amounts of the Company’s debt obligations approximate fair value based on future payments discounted at current interest rates for similar obligations or interest rates which fluctuate with the market.

SigmaTron International, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

April 30, 2013 and 2012

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Fair-Value of Financial Instruments - Continued

The Company measured the net assets included in the Spitfire acquisition under the fair value standard (primarily using level 3 measurement inputs) including the contingent consideration. The Company currently does not have any other non-financial assets and non-financial liabilities that are required to be measured at fair value on a recurring basis.

Goodwill and Other Intangible Assets

Goodwill represents the purchase price in excess of the fair value of assets acquired in business combinations. The Company assesses goodwill for impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. The Company is permitted the option to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the fair value of any reporting unit is less than its corresponding carrying value. If, after assessing the totality of events and circumstances, the Company concludes that it is not more likely than not that the fair value of any reporting unit is less than its corresponding carrying value then the Company is not required to take further action. However, if the Company concludes otherwise, then it is required to perform a quantitative impairment test, including computing the fair value of the reporting unit and comparing that value to its carrying value. If the fair value is less than its carrying value, a second step of the test is required to determine if recorded goodwill is impaired. The Company also has the option to bypass the qualitative assessment for goodwill in any period and proceed directly to performing the quantitative impairment test. The Company will be able to resume performing the qualitative assessment in any subsequent period. The Company performed its annual goodwill impairment test as of February 1, 2013 and determined that no impairment existed as of the date of the impairment test.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including amortizable intangible assets for impairment. Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company’s impairment review is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. The Company conducts annual reviews for idle and underutilized equipment, and review business plans for possible impairment. Impairment occurs when the carrying value of the assets exceeds the future

undiscounted cash flows expected to be earned by the use of the asset group. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

Stock Incentive Plans

Under the Company’s stock option plans, options to acquire shares of common stock have been made available for grant to certain employees and directors. Each option granted has an exercise price of not less than 100% of the market value of the common stock on the date of grant. The contractual life of each option is generally 10 years. The vesting of the grants varies according to the individual options granted. The Company measures the cost of employee services received in exchange for an equity award based on the grant date fair value and records that cost over the respective vesting period of the award.

Reclassifications

Certain reclassifications have been made to the previously reported 2012 financial statements to conform to the 2013 presentation.

New Accounting Standards

There are no recent accounting standards that had, or are expected to have, a significant effect on these consolidated financial statements.

Spitfire Control, Inc.

The Purchase Agreement

SigmaTron signed a Purchase Agreement on May 31, 2012 with Spitfire Control, Inc., an Illinois corporation (“Seller”), regarding the acquisition of certain assets of the Seller by the Company (the “Transaction”). Prior to the date of the Purchase Agreement, the Seller and its affiliates were customers and strategic partners of the Company, with such relationships dating back to 1994.

Seller, on its own and through its subsidiaries Digital Appliance Controls de Mexico, S.A. de C.V., a Mexico corporation (“DAC”), and Spitfire Controls (Cayman) Co. Ltd., a Cayman Islands exempted company (“Cayman”), their subsidiaries and Seller’s affiliated entities, was engaged in the business of the design, manufacture, sale and distribution of electrical or electronic controls for appliances (the “Business”).

The acquired assets consisted of (i) all of the equity securities of DAC and Cayman and (ii) all of the assets used by or useful in the conduct of the Business. In addition the Company also obtained from the Seller an agreement not to compete against the Business as it is operated by the Company after the closing of the Transaction.

In consideration, the Company agreed to pay a purchase price consisting of: (i) the satisfaction and release of the account payable of $16,455,000 owed by Seller to the Company; (ii) future payments, which are based upon the annual post-closing performance of the Business during each of the Company’s fiscal years 2013 through 2019; and (iii) the issuance of 50,000 shares of restricted common stock of SigmaTron, 12,500 of which vested upon the closing of the Transaction and 12,500 of which will vest on each of the first, second and third anniversaries of the closing of the Transaction.

In addition to the foregoing, the Company agreed to assume (i) the Seller’s obligations under certain specified contracts and Governmental Authorizations (as defined in the Purchase Agreement), (ii) specified trade accounts payable and accrued expenses of the Seller as agreed upon by the parties and (iii) specified inter-company payables involving the Seller, DAC, Cayman and/or their subsidiaries and associated companies. Further, each of DAC and Cayman retained the liabilities associated with its respective operations, which is customary in transactions involving the purchase or sale of all of the equity securities of an entity. As a result, the Company indirectly acquired such liabilities.

The Credit Amendment

Concurrent with the Transaction, the Company entered into amendments of its credit facility with Wells Fargo (“the Credit Amendment”). The Credit Amendment modified certain financial covenant thresholds applicable to the Company, added property acquired in the Transaction as collateral for the loan to the Company, permitted the Company to acquire certain inter-company payables involving the Seller, DAC, Cayman or the subsidiaries and associated companies and permitted the Company to discharge and release the account payable owed by the Seller to the Company in partial consideration for the Transaction.

Reasons for the Transaction

The Company believes its acquisition of the Business will allow a comprehensive approach to solving major appliance producers’ issues with integrating electronics into their platforms. The acquisition also added two manufacturing operations in locations that the Company believes will augment the Company’s international footprint. In addition, the acquisition of the Business will allow the Company to offer design services for the first time in specific markets. In conjunction with the acquisition, professional fees incurred during fiscal 2013 and 2012, were $803,006 and $530,565, respectively. The professional fees were recorded as selling and administrative expenses.

Accounting

The acquisition was recorded using the purchase method of accounting, and on the date of the acquisition, the Company assessed the fair value of the acquired assets and assumed liabilities (primarily using level 3 measurement inputs) and an allocated purchase price of $18,944,307. The allocation of the purchase considerations was based upon estimates made by the Company with the assistance of independent valuation specialists. The revised purchase price allocation as of May 31, 2012, was as follows:

	Estimated Fair Value
Cash	$	1,142,597
Current assets		10,074,168
Property, machinery and equipment		1,400,250
Current liabilities		(3,037,607	)

The amounts allocated to relationships, backlog, trade names, non-compete agreements and patents are estimated by the Company based on the analysis performed by independent valuation specialists, primarily through the use of discounted cash flow techniques. Appraisal assumptions utilized under these methods include a forecast of estimated future net cash flows, as well as discounting the future net cash flows to their present value. Acquired intangible assets are being amortized over the estimated useful lives as set forth in the following table:

	Method	Life
Customer relationships	Accelerated	15 Years
Backlog	Straight-line	1 Year
Trade names	Straight-line	20 Years
Non-compete agreements	Straight-line	7 Years
Patents	Straight-line	5 Years

The estimated asset lives are determined based on projected future economic benefits and expected life cycles of the acquired intangible assets. The amount assigned to goodwill is not being amortized, but will be tested for impairment annually or under circumstances that may indicate a potential impairment. Goodwill is deductible for federal income tax purposes over a period of 15 years.

The Company’s estimate of the fair value of the contingent consideration ($2,320,000 as of the acquisition date) was based on expected operating results of the Business through fiscal 2019 and the specific terms of when such consideration would be earned. Those terms provide for additional consideration to be paid to Seller or its owner based on a percentage of sales and pre-tax profits over those years in excess of certain minimums. The Company discounted expected payments by its weighted average cost of capital of 11.5%. Payments are to be made quarterly each year and adjusted after each year end audit. The Company has made three quarterly payments of $65,000 each in fiscal 2013. As of April 30, 2013, the Company had not changed its estimated aggregate consideration expected to be earned under this arrangement. Any changes in the Company’s estimate will be reflected as a change in the contingent consideration liability and as additional or credits to selling and administrative expenses, as will changes in the current fair value caused by the continual decrease in the discount period between the current balance sheet date and the estimated payout dates. Such fair value changes were not material during fiscal 2013. The value of the 50,000 shares of restricted stock issued as part of the purchase price was $169,011 based on the trading price of the Company’s common stock on the acquisition date discounted by 15% to account for the restrictions associated with that issuance.

Due to the acquisition of Spitfire, effective June 1, 2012, the Company discontinued selling to Spitfire and instead began selling directly to Spitfire’s former customers.

The results of the Business for the period June 1, 2012 through April 30, 2013 have been included in the consolidated financial statement for the twelve month period ended April 30, 2013 and includes sales of $26,779,273 and a net loss of $2,513,151. Offsetting some of such sales are the sales that SigmaTron would have recorded to Spitfire had SigmaTron not acquired the Business.

NOTE O - STOCK OPTIONS

The Company has stock option plans (“Option Plans”) under which certain employees and non-employee directors may acquire up to 1,753,500 shares of common stock. Options available for grant under the employee plans total 1,357,500, with the non-employee director plans allowing for a total of 396,000 options available for grant. All Option Plans have been approved by the Company’s shareholders. At April 30, 2013, the Company has 90,864 shares available for future issuance to employees under the employee plan and none under the non-employee director plan. The Option Plans are interpreted and administered by the Compensation Committee of the Board of Directors. The maximum term of options granted under the Option Plans is generally 10 years. Options granted under the Option Plans are either incentive stock options or nonqualified options. Each Option under the Option Plans is exercisable for one share of stock. Options forfeited under the Option Plans are available for reissuance. Options granted under these plans are granted at an exercise price equal to the fair market value of a share of the Company’s common stock on the date of grant.

There were 115,000 options granted during fiscal year 2013. The weighted-average grant date fair value of the options granted during fiscal year 2013 was $3.60. There were no options granted during fiscal year 2012.

NOTE O - STOCK OPTIONS - Continued

The Company issued 25,000 shares of restricted stock during fiscal year 2013. In addition, the Company issued 50,000 shares of restricted stock as additional consideration with the May 31, 2012 Spitfire acquisition. There were no shares of restricted stock issued during fiscal year 2012.

The fair value of each option grant is estimated on the grant date using the Black-Scholes option pricing model with the following assumptions:

	2013			2012
Expected dividend yield		0	%		N/A
Expected stock price volatility		.75	%		N/A
Average risk-free interest rate		.72	%		N/A
Weighted-average expected life of options		5.5 years			N/A

Option-valuation models require the input of highly subjective assumptions. Because the Company’s stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing method does not necessarily provide a reliable single measure of the fair value of the Company’s stock options. When the Company does grant stock options, it uses the U.S. Treasury yield in effect at the time of the option grant to calculate the risk-free interest rate and the simplified method to calculate the weighted-average expected life, due to limited history. The expected dividend, volatility and forfeitures rates of options are based on historical experience and expected future results. The vesting period of the stock options ranges from three to five years.

The Company has not recorded U.S. income taxes for a significant portion of undistributed earnings of the Company’s foreign subsidiaries, since these earnings have been and under current plans will continue to be, permanently reinvested in these foreign subsidiaries. The cumulative amount of unremitted earnings for which U.S. income taxes have not been recorded is approximately $11,300,000. It is not practicable to estimate the amount of additional taxes that may be payable upon distribution.

At April 30, 2013, the Company had unused Federal net operating loss carryforwards totaling approximately $1,500,000 that will expire in the fiscal year ended April 30, 2033. The Company has unused state net operating loss carryforwards of approximately $1,290,000 that will begin to expire in the fiscal year ended April 30, 2023. The Company has unused foreign net operating loss carryforwards of approximately $1,090,000 that will begin to expire in the calendar year 2013. A full valuation allowance has been provided against the foreign net operating loss carryforwards.

The Company operates under a tax incentive arrangement in Vietnam which provided for a 0% tax rate through December 2012 and provides a reduced tax rate ranging from 7.5% to 12.5% from January 2013 through December 2019. The tax holiday is conditioned upon meeting certain investment thresholds which have thus far been met.

Other

The Company has no unrecognized tax benefits at April 30, 2013 and 2012 and none were recorded or reversed in either fiscal year.

Interest related to tax positions taken in the Company’s tax returns are recorded in income tax expense in the Consolidated Statements of Income. The Company did not record penalties in the Consolidated Statements of Income.

The Company completed an examination with the Internal Revenue Service related to fiscal years 2008 and 2009. The completion of the examination had no impact on the amount of the unrecognized tax benefits. The settlement of the examination resulted in an increase to tax expense of $6,143 related to interest on a deficiency notice.

The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, the Company is no longer subject to state, local or foreign examinations by tax authorities for fiscal years before 2008. The Company is no longer subject to U.S. Federal examinations by tax authorities for fiscal years before 2010.

Summary of Significant Accounting Policies (Policies)

Apr. 30, 2013

Consolidation Policy

Consolidation Policy

The consolidated financial statements include the accounts and transactions of SigmaTron International, Inc. (“SigmaTron”), its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls (Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Suzhou SigmaTron Electronics Co. Ltd., and SigmaTron Electronic Technology Co., Ltd. (collectively, “SigmaTron China”), and its international procurement office, SigmaTron Taiwan. The functional currency of the Mexican, Vietnamese and Chinese subsidiaries and procurement branch is the U.S. dollar. Intercompany transactions are eliminated in the consolidated financial statements. The impact of currency fluctuation for the fiscal year ended April 30, 2013 resulted in a loss of approximately $359,000, compared to a gain of approximately $134,000 for the prior fiscal year.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant

estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include cash and all highly liquid short-term investments maturing within three months of the purchase date.

Accounts Receivable

Accounts Receivable

The majority of the Company’s accounts receivable are due from companies in the consumer electronics, gaming, fitness, industrial electronics, medical/life sciences, semiconductor, telecommunications and appliance industries. Credit is extended based on evaluation of a customer’s financial condition, and, generally, collateral is not required. Accounts receivable are due in accordance with agreed upon terms, and are stated at amounts due from customers net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payments terms are considered past due. The Company writes off accounts receivable when they are determined to be uncollectible.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

The Company’s allowance for doubtful accounts relates to receivables not expected to be collected from its customers. This allowance is based on management’s assessment of specific customer balances, considering the age of receivables and financial stability of the customer and a five year average of prior uncollectible amounts. If there is an adverse change in the financial condition of the Company’s customers, or if actual defaults are higher than provided for, an addition to the allowance may be necessary.

Inventories

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out method. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or market. The Company establishes inventory reserves for valuation, shrinkage, and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of

products sold. The Company records provisions for excess and obsolete inventories for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Actual product demand or market conditions could be different than that projected by management.

Property, Machinery and Equipment

Property, Machinery and Equipment

Property, machinery and equipment are valued at cost. The Company provides for depreciation and amortization using the straight-line method over the estimated useful life of the assets:

Buildings	20 years
Machinery and equipment	5-12 years
Office equipment and software	3-5 years
Tools and dies	12 months
Leasehold improvements	term of lease

Expenses for repairs and maintenance are charged to selling and administrative expenses as incurred.

Deferred Financing Costs

Deferred Financing Costs

Deferred financing costs consist of costs incurred to obtain the Company’s long-term debt and are amortized using the straight-line method over the term of the related debt. Deferred financing fees of $70,776 and $8,756, net of accumulated amortization of $270,983 and $238,354 as of April 30, 2013 and 2012, respectively, are classified in other long-term assets on the Company’s balance sheet.

Income Taxes

Income Taxes

Deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred income tax assets to an amount more likely than not to be realized.

A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits.

The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increase or decreases to income tax expense in the period in which they are determined.

Earnings per Share

Earnings per Share

Basic earnings per share are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common stock equivalents such as stock options and restricted stock, had been exercised or vested. At April 30, 2013 and 2012, there were 400,190 anti-dilutive common stock equivalents, which have been excluded from the calculation of diluted earnings per share.

Revenue Recognition

Revenue Recognition

Revenues from sales of the Companys’ electronic manufacturing services business are recognized when the finished good product is shipped to the customer. In general, and except for consignment inventory, it is the Companys’ policy to recognize revenue and related costs when the finished goods have been shipped from our facilities, which is also the same point that title passes under the terms of the purchase order. Finished goods inventory for certain customers is shipped from the Company to an independent warehouse for storage or shipped directly to the customer and stored in a segregated part of the customer’s own facility. Upon the customer’s request for finished goods inventory, the inventory is shipped to the customer if the inventory was stored off-site, or transferred from the segregated part of the customer’s facility for consumption or use by the customer. The Company recognizes revenue upon such shipment or transfer. The Company does not earn a fee for such arrangements. The Company from time to time may ship finished goods from its facilities, which is also the same point that title passes under the terms of the purchase order, and invoice the customer at the end of the calendar month. This is done only in special circumstances to accommodate a specific customer. Further, from time to time customers request the Company hold finished goods after they have been invoiced to consolidate finished goods for shipping purposes. The Company generally provides a 90 day warranty for workmanship only and does not have any installation, acceptance or sales incentives (although the Company has negotiated longer warranty terms in certain instances). The Company assembles and tests assemblies based on customers’ specifications. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties.

Shipping and Handling Costs

Shipping and Handling Costs

The Company records shipping and handling costs as selling and administrative expenses. Customers are typically invoiced for shipping costs. Shipping and handling costs were not material to the financial statements for fiscal years 2013 or 2012.

Fair Value Measurements

Fair Value Measurements

Fair value measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. The Company utilizes a fair value hierarchy based upon the observability of inputs used in valuation techniques as follows:

Level 1:	Observable inputs such as quoted prices in active markets;
Level 2:	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
Level 3:	Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, receivables, accounts payable and accrued expenses which approximate fair value at April 30, 2013, due to their short-term nature. The carrying amounts of the Company’s debt obligations approximate fair value based on future payments discounted at current interest rates for similar obligations or interest rates which fluctuate with the market.

The Company measured the net assets included in the Spitfire acquisition under the fair value standard (primarily using level 3 measurement inputs) including the contingent consideration. The Company currently does not have any other non-financial assets and non-financial liabilities that are required to be measured at fair value on a recurring basis.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

Goodwill represents the purchase price in excess of the fair value of assets acquired in business combinations. The Company assesses goodwill for impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. The Company is permitted the option to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the fair value of any reporting unit is less than its corresponding carrying value. If, after assessing the totality of events and circumstances, the Company concludes that it is not more likely than not that the fair value of any reporting unit is less than its corresponding carrying value then the Company is not required to take further action. However, if the Company concludes otherwise, then it is required to perform a quantitative impairment test, including computing the fair value of the reporting unit and comparing that value to its carrying value. If the fair value is less than its carrying value, a second step of the test is required to determine if recorded goodwill is impaired. The Company also has the option to bypass the qualitative assessment for goodwill in any period and proceed directly to performing the quantitative impairment test. The Company will be able to resume performing the qualitative assessment in any subsequent period. The Company performed its annual goodwill impairment test as of February 1, 2013 and determined that no impairment existed as of the date of the impairment test.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including amortizable intangible assets for impairment. Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company’s impairment review is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. The Company conducts annual reviews for idle and underutilized equipment, and review business plans for possible impairment. Impairment occurs when the carrying value of the assets exceeds the future undiscounted cash flows expected to be earned by the use of the asset group. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

Stock Incentive Plans

Stock Incentive Plans

Under the Company’s stock option plans, options to acquire shares of common stock have been made available for grant to certain employees and directors. Each option granted has an exercise price of not less than 100% of the market value of the common stock on the date of grant. The contractual life of each option is generally 10 years. The vesting of the grants varies according to the individual options granted. The Company measures the cost of employee services received in exchange for an equity award based on the grant date fair value and records that cost over the respective vesting period of the award.

Reclassifications

Reclassifications

Certain reclassifications have been made to the previously reported 2012 financial statements to conform to the 2013 presentation.

Apr. 30, 2013

Summary of Significant Accounting Policies

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The consolidated financial statements include the accounts and transactions of SigmaTron International, Inc. (“SigmaTron”), its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls (Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Suzhou SigmaTron Electronics Co. Ltd., and SigmaTron Electronic Technology Co., Ltd. (collectively, “SigmaTron China”), and its international procurement office, SigmaTron Taiwan. The functional currency of the Mexican, Vietnamese and Chinese subsidiaries and procurement branch is the U.S. dollar. Intercompany transactions are eliminated in the consolidated financial statements. The impact of currency fluctuation for the fiscal year ended April 30, 2013 resulted in a loss of approximately $359,000, compared to a gain of approximately $134,000 for the prior fiscal year.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant

estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash and all highly liquid short-term investments maturing within three months of the purchase date.

Accounts Receivable

The majority of the Company’s accounts receivable are due from companies in the consumer electronics, gaming, fitness, industrial electronics, medical/life sciences, semiconductor, telecommunications and appliance industries. Credit is extended based on evaluation of a customer’s financial condition, and, generally, collateral is not required. Accounts receivable are due in accordance with agreed upon terms, and are stated at amounts due from customers net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payments terms are considered past due. The Company writes off accounts receivable when they are determined to be uncollectible.

Allowance for Doubtful Accounts

The Company’s allowance for doubtful accounts relates to receivables not expected to be collected from its customers. This allowance is based on management’s assessment of specific customer balances, considering the age of receivables and financial stability of the customer and a five year average of prior uncollectible amounts. If there is an adverse change in the financial condition of the Company’s customers, or if actual defaults are higher than provided for, an addition to the allowance may be necessary.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out method. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or market. The Company establishes inventory reserves for valuation, shrinkage, and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of

products sold. The Company records provisions for excess and obsolete inventories for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Actual product demand or market conditions could be different than that projected by management.

Expenses for repairs and maintenance are charged to selling and administrative expenses as incurred.

Deferred Financing Costs

Deferred financing costs consist of costs incurred to obtain the Company’s long-term debt and are amortized using the straight-line method over the term of the related debt. Deferred financing fees of $70,776 and $8,756, net of accumulated amortization of $270,983 and $238,354 as of April 30, 2013 and 2012, respectively, are classified in other long-term assets on the Company’s balance sheet.

Note Payable - Bank

The Company has a senior secured credit facility with Wells Fargo Bank, N.A. (“Wells Fargo”), with a credit limit up to $30 million and an initial term through September 30, 2013. The facility allows the Company to choose among interest rates at which it may borrow funds. The interest rate is the prime rate plus one half percent (effectively, 3.75% at April 30, 2013) or LIBOR plus two and three quarter percent (effectively, 3.0% at April 30, 2013), which is paid monthly. The credit facility is collateralized by substantially all of the domestically located assets of the Company and requires the Company to be in compliance with several financial covenants. In conjunction with the Spitfire acquisition, two of the financial covenants required by terms of the

Company’s senior secured credit facility was amended as of May 31, 2012. The Company was in violation of certain of its financial covenants at July 31, 2012 and received a waiver for the financial covenant violations. The Company renegotiated its financial covenants during the quarter ended October 31, 2012 with Wells Fargo and extended the credit facility through September 30, 2014. As of April 30, 2013, the Company again amended its credit agreement and renegotiated two of the financial covenants required by the terms of the Company’s senior secured credit facility. At April 30, 2013, the Company was in compliance with its amended financial covenants.

Aquisition

NOTE G - ACQUISITION

Spitfire Control, Inc.

The Purchase Agreement

SigmaTron signed a Purchase Agreement on May 31, 2012 with Spitfire Control, Inc., an Illinois corporation (“Seller”), regarding the acquisition of certain assets of the Seller by the Company (the “Transaction”). Prior to the date of the Purchase Agreement, the Seller and its affiliates were customers and strategic partners of the Company, with such relationships dating back to 1994.

Seller, on its own and through its subsidiaries Digital Appliance Controls de Mexico, S.A. de C.V., a Mexico corporation (“DAC”), and Spitfire Controls (Cayman) Co. Ltd., a Cayman Islands exempted company (“Cayman”), their subsidiaries and Seller’s affiliated entities, was engaged in the business of the design, manufacture, sale and distribution of electrical or electronic controls for appliances (the “Business”).

The acquired assets consisted of (i) all of the equity securities of DAC and Cayman and (ii) all of the assets used by or useful in the conduct of the Business. In addition the Company also obtained from the Seller an agreement not to compete against the Business as it is operated by the Company after the closing of the Transaction.

In consideration, the Company agreed to pay a purchase price consisting of: (i) the satisfaction and release of the account payable of $16,455,000 owed by Seller to the Company; (ii) future payments, which are based upon the annual post-closing performance of the Business during each of the Company’s fiscal years 2013 through 2019; and (iii) the issuance of 50,000 shares of restricted common stock of SigmaTron, 12,500 of which vested upon the closing of the Transaction and 12,500 of which will vest on each of the first, second and third anniversaries of the closing of the Transaction.

In addition to the foregoing, the Company agreed to assume (i) the Seller’s obligations under certain specified contracts and Governmental Authorizations (as defined in the Purchase Agreement), (ii) specified trade accounts payable and accrued expenses of the Seller as agreed upon by the parties and (iii) specified inter-company payables involving the Seller, DAC, Cayman and/or their subsidiaries and associated companies. Further, each of DAC and Cayman retained the liabilities associated with its respective operations, which is customary in transactions involving the purchase or sale of all of the equity securities of an entity. As a result, the Company indirectly acquired such liabilities.

The Credit Amendment

Concurrent with the Transaction, the Company entered into amendments of its credit facility with Wells Fargo (“the Credit Amendment”). The Credit Amendment modified certain financial covenant thresholds applicable to the Company, added property acquired in the Transaction as collateral for the loan to the Company, permitted the Company to acquire certain inter-company payables involving the Seller, DAC, Cayman or the subsidiaries and associated companies and permitted the Company to discharge and release the account payable owed by the Seller to the Company in partial consideration for the Transaction.

Reasons for the Transaction

The Company believes its acquisition of the Business will allow a comprehensive approach to solving major appliance producers’ issues with integrating electronics into their platforms. The acquisition also added two manufacturing operations in locations that the Company believes will augment the Company’s international footprint. In addition, the acquisition of the Business will allow the Company to offer design services for the first time in specific markets. In conjunction with the acquisition, professional fees incurred during fiscal 2013 and 2012, were $803,006 and $530,565, respectively. The professional fees were recorded as selling and administrative expenses.

Accounting

The acquisition was recorded using the purchase method of accounting, and on the date of the acquisition, the Company assessed the fair value of the acquired assets and assumed liabilities (primarily using level 3 measurement inputs) and an allocated purchase price of $18,944,307. The allocation of the purchase considerations was based upon estimates made by the Company with the assistance of independent valuation specialists. The revised purchase price allocation as of May 31, 2012, was as follows:

	Estimated Fair Value
Cash	$	1,142,597
Current assets		10,074,168
Property, machinery and equipment		1,400,250
Current liabilities		(3,037,607	)
Customer relationships		4,690,000
Backlog		22,000
Trade names		980,000
Non-compete agreements		50,000
Patents		400,000
Goodwill		3,222,899
Total Net Assets	$	18,944,307

The amounts allocated to relationships, backlog, trade names, non-compete agreements and patents are estimated by the Company based on the analysis performed by independent valuation specialists, primarily through the use of discounted cash flow techniques. Appraisal assumptions utilized under these methods include a forecast of estimated future net cash flows, as well as discounting the future net cash flows to their present value. Acquired intangible assets are being amortized over the estimated useful lives as set forth in the following table:

	Method	Life
Customer relationships	Accelerated	15 Years
Backlog	Straight-line	1 Year
Trade names	Straight-line	20 Years
Non-compete agreements	Straight-line	7 Years
Patents	Straight-line	5 Years
Goodwill	N/A	Indefinite

The estimated asset lives are determined based on projected future economic benefits and expected life cycles of the acquired intangible assets. The amount assigned to goodwill is not being amortized, but will be tested for impairment annually or under circumstances that may indicate a potential impairment. Goodwill is deductible for federal income tax purposes over a period of 15 years.

The Company’s estimate of the fair value of the contingent consideration ($2,320,000 as of the acquisition date) was based on expected operating results of the Business through fiscal 2019 and the specific terms of when such consideration would be earned. Those terms provide for additional consideration to be paid to Seller or its owner based on a percentage of sales and pre-tax profits over those years in excess of certain minimums. The Company discounted expected payments by its weighted average cost of capital of 11.5%. Payments are to be made quarterly each year and adjusted after each year end audit. The Company has made three quarterly payments of $65,000 each in fiscal 2013. As of April 30, 2013, the Company had not changed its estimated aggregate consideration expected to be earned under this arrangement. Any changes in the Company’s estimate will be reflected as a change in the contingent consideration liability and as additional or credits to selling and administrative expenses, as will changes in the current fair value caused by the continual decrease in the discount period between the current balance sheet date and the estimated payout dates. Such fair value changes were not material during fiscal 2013. The value of the 50,000 shares of restricted stock issued as part of the purchase price was $169,011 based on the trading price of the Company’s common stock on the acquisition date discounted by 15% to account for the restrictions associated with that issuance.

Due to the acquisition of Spitfire, effective June 1, 2012, the Company discontinued selling to Spitfire and instead began selling directly to Spitfire’s former customers.

The results of the Business for the period June 1, 2012 through April 30, 2013 have been included in the consolidated financial statement for the twelve month period ended April 30, 2013 and includes sales of $26,779,273 and a net loss of $2,513,151. Offsetting some of such sales are the sales that SigmaTron would have recorded to Spitfire had SigmaTron not acquired the Business.

Stock Options

Stock Options

NOTE O - STOCK OPTIONS

The Company has stock option plans (“Option Plans”) under which certain employees and non-employee directors may acquire up to 1,753,500 shares of common stock. Options available for grant under the employee plans total 1,357,500, with the non-employee director plans allowing for a total of 396,000 options available for grant. All Option Plans have been approved by the Company’s shareholders. At April 30, 2013, the Company has 90,864 shares available for future issuance to employees under the employee plan and none under the non-employee director plan. The Option Plans are interpreted and administered by the Compensation Committee of the Board of Directors. The maximum term of options granted under the Option Plans is generally 10 years. Options granted under the Option Plans are either incentive stock options or nonqualified options. Each Option under the Option Plans is exercisable for one share of stock. Options forfeited under the Option Plans are available for reissuance. Options granted under these plans are granted at an exercise price equal to the fair market value of a share of the Company’s common stock on the date of grant.

There were 115,000 options granted during fiscal year 2013. The weighted-average grant date fair value of the options granted during fiscal year 2013 was $3.60. There were no options granted during fiscal year 2012.

The Company issued 25,000 shares of restricted stock during fiscal year 2013. In addition, the Company issued 50,000 shares of restricted stock as additional consideration with the May 31, 2012 Spitfire acquisition. There were no shares of restricted stock issued during fiscal year 2012.

The fair value of each option grant is estimated on the grant date using the Black-Scholes option pricing model with the following assumptions:

	2013			2012
Expected dividend yield		0	%		N/A
Expected stock price volatility		.75	%		N/A
Average risk-free interest rate		.72	%		N/A
Weighted-average expected life of options		5.5 years			N/A

Option-valuation models require the input of highly subjective assumptions. Because the Company’s stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing method does not necessarily provide a reliable single measure of the fair value of the Company’s stock options. When the Company does grant stock options, it uses the U.S. Treasury yield in effect at the time of the option grant to calculate the risk-free interest rate and the simplified method to calculate the weighted-average expected life, due to limited history. The expected dividend, volatility and forfeitures rates of options are based on historical experience and expected future results. The vesting period of the stock options ranges from three to five years.

The table below summarizes option activity through April 30, 2013:

	Number of securities to be issued upon exercise of outstanding options			Weighted- average exercise price		Number of options exercisable at end of year
Outstanding at April 30, 2011		459,589		$	8.42		458,337
Options exercised during 2012		(45,298	)		2.20
Options expired during 2012		(4,099	)		3.69
Outstanding at April 30, 2012		410,192			9.16		410,192
Options granted during 2013		115,000			3.60
Options exercised during 2013		(10,000	)		3.99
Outstanding at April 30, 2013		515,192		$	8.02		438,142

Intrinsic value is calculated as the positive difference between the market price of the Company’s common stock and the exercise price of the underlying options. During the fiscal years ended April 30, 2013 and 2012, the aggregate intrinsic value of options exercised was $1,400 and $71,118 respectively. As of April 30, 2013 and 2012, the aggregate intrinsic value of in the money options outstanding was $60,950 and $0, respectively.

Information with respect to stock options outstanding at April 30, 2013, follows:

	Options outstanding
Range of exercise prices	Number outstanding at April 30, 2013		Weighted-average remaining contractual life	Weighted- average exercise price
