TABLE OF CONTENTS

PART I

Wireless Telecom Group, Inc., a New Jersey corporation (“we”, “us” or the “Company”), designs and manufactures radio frequency (“RF”) and microwave-based products for wireless and advanced communications industries and currently markets its products and services worldwide under the Boonton, Microlab and Noisecom® brands. Our complementary suite of high performance instruments and components includes peak power meters, signal analyzers, RF passive components and integrated subsystems, noise modules and precision noise generators. The Company serves both commercial and government markets with workflow-oriented, built-for-purpose solutions in distributed antenna systems (“DAS”), cellular/mobile, WiFi, WiMAX, private mobile radio, satellite, cable, radar, avionics, medical, and computing applications. The consolidated financial statements include the accounts of Wireless Telecom Group, Inc., doing business as, and operating under the trade name, Noise Com, Inc., and its wholly-owned subsidiaries Boonton Electronics Corporation, Microlab/FXR, WTG Foreign Sales Corporation and NC Mahwah, Inc. The corporate website address is www.wtcom.com.

The Company presents its operations in two reportable segments: (1) network solutions and (2) test and measurement. The network solutions segment is comprised primarily of the operations of Microlab. The test and measurement segment is comprised primarily of the operations of Boonton and Noisecom.

Sales by reportable segment for the years ended December 31, 2013 and 2012 were as follows:

Additional financial information on the Company’s reportable segments for each of the last two years is included in the Company’s Notes to the consolidated financial statements (see Note 7, “Segment and Related Information”) included in Item 8 herein.

Market

Since the Company’s incorporation in the State of New Jersey in 1985, it has been primarily engaged in supplying noise source products and electronic testing and measurement instruments and passive components to various customers. Approximately 86% and 76% of the Company’s consolidated sales in fiscal 2013 and 2012, respectively, were derived from commercial customers. The remaining consolidated sales (approximately 14% and 24%, respectively) were comprised of sales made to the United States government (particularly the armed forces) and prime defense contractors.

Products

The Company, through its Microlab subsidiary, designs and manufactures a wide selection of RF passive components and integrated subsystems for signal conditioning and distribution in the wireless infrastructure markets, particularly for DAS, the in-building wireless solutions industry, radio base-station market and medical equipment sector. Microlab’s passive RF components share unique capabilities in the area of broadband frequency coverage, minimal loss and low Passive Intermodulation (“PIM”).

Microlab product offerings include: neutral host DAS and co-siting combiner solutions, hybrid couplers and hybrid matrices, cross band couplers, attenuators, RF terminations, RF power splitter and diplexers, as well as RF combiners and broadband combiner boxes for in-building DAS deployments.

The Company, through its Boonton subsidiary, designs and produces electronic test and measurement equipment including power meters, voltmeters, capacitance meters, audio and modulation meters, portable passive intermodulation test equipment for field-based testing of cellular transmission signals and accessory products.

These products measure the power of RF and microwave systems used by the military and in commercial sectors like telecommunications.

Boonton products are also used to test terrestrial and satellite communications, radar and telemetry. Certain power meter products are designed for measuring signals based on wideband modulation formats, allowing a variety of measurements to be made, including maximum power, peak power, average power and minimum power.

The Company’s noise components and instruments (noise source products) are used as a method to provide wide band signals for sophisticated telecommunication and defense applications, and as a stable reference standard for instruments and systems, including radar and satellite communications. Furthermore, noise sources can simulate challenging signaling conditions in data and RF transmission systems. Examples are jitter testing for high speed data lines used in modern computer architecture and signal to noise measurements to optimize wireless receivers and transmitters. Additionally, noise sources are used for jamming RF signals, and blocking or disturbing enemy radar and other communications, as well as insulating and protecting friendly communications.

Noise sources also are used in radar systems as part of built-in test equipment to continuously monitor the radar receiver and in satellite communications where the use of back-up receivers are becoming more common as the demand for communication availability and reliability is increasing. This test assures that the back-up receiver is always functional and ready.

The Company also offers a line of broadband test sources serving the Cable Television and Cable Modem industry, including measurement solutions for CATV equipment, Data-Over-Cable (“DOCSIS”) and Digital TV.

The Company’s products consist of several models with varying degrees of capabilities which can be customized to meet particular customer requirements. They may be incorporated directly into the electronic equipment concerned or may be stand-alone components or devices that are connected to, or used in conjunction with, such equipment operating from an external site, in the factory or in the field. Prices of products range from approximately $100 to $100,000 per unit, with most sales occurring between $2,000 and $35,000 per unit.

The Company’s products have extended useful lives and the Company provides recalibration services for its instrument products to ensure their accuracy, for a fee, to its domestic and international customers, and also calibrates test equipment manufactured by others. Such services accounted for approximately 4% of consolidated sales for each of the years 2013 and 2012.

Marketing and Sales

As of March 28, 2014, the Company’s in-house marketing and sales force consisted of twenty-three individuals. The Company promotes the sale of its products to customers and manufacturers’ representatives through its web-site, product literature, publication of articles, presentations at technical conferences, direct mailings, trade advertisements and trade show exhibitions.

The Company’s products are sold globally through its in-house sales people and by over one hundred manufacturers’ representatives and distributors (the Company’s channel partners). Generally, our channel partners do not stock inventories of the Company’s products. Channel partners accounted for 75% and 74% of the Company’s consolidated sales for the years ended December 31, 2013 and 2012, respectively. For the years ended December 31, 2013 and 2012, no channel partner accounted for more than 10% of total consolidated sales. The Company does not believe that the loss of any single channel partner would have a material adverse affect on its business.

The Company’s relationship with its channel partners is usually governed by written contracts that either run for one-year renewable periods terminable by either party on 60 days prior notice or have indefinite lives terminable by either party on 60 days prior notice. The contracts generally provide for territorial and product representation. The Company continually reviews and assesses the performance of its channel partners and makes changes from time to time based on such assessments.

Management believes that its products offer state-of-the-art performance combined with outstanding customer and technical support. The Company has always placed great emphasis on designing its products to be user-friendly.

Customers

The Company currently sells the majority of its products to various commercial users in the communications industry. Other sales are made to large defense contractors, which incorporate the Company’s products into their products for sale to the U.S. and foreign governments, multi-national concerns and Fortune 500 companies.

For each of the years 2013 and 2012, one customer accounted for 11% of total consolidated sales. The Company’s largest customers vary from year to year. Accordingly, while the complete loss of any large customer or substantial reduction of sales to such customers could have a material adverse affect on the Company, the Company has experienced shifts in sales patterns with such large companies in the past without any material adverse affect. There can be no assurance, however, that the Company will not experience future shifts in sales patterns not having a material adverse affect on its business.

Regional consolidated sales from operations for fiscal 2013 were made to customers in the Americas ($26,760,912 or 79% of total consolidated sales), Europe, Middle East and Africa ($4,434,037 or 13% of total consolidated sales) and Asia Pacific ($2,630,124 or 8% of total consolidated sales).

Research and Development

The Company currently maintains an engineering staff (twenty-one individuals as of March 28, 2014) whose duties include the improvement of existing products, modification of products to meet customer needs and the engineering, research and development of new products and applications. Expenses for research and development involve engineering for improvements and development of new products for commercial markets. Such expenditures for operations include the cost of engineering services and engineering support personnel and were approximately $2,645,000 and $2,524,000 for the years ended December 31, 2013 and 2012, respectively.

Competition

The Company competes against many companies, which utilize similar technology to that of the Company, some of which are larger and have substantially greater resources and expertise in financial, technical and marketing areas than the Company. Some of these companies include Agilent Technologies, Inc., Rhode & Schwartz GmbH & Co. KG, Anritsu Corporation, Kathrein, Commscope, Westell Technologies, Inc. and Aeroflex Holding Corp. The Company competes by having a niche in several product areas where it capitalizes on its expertise in manufacturing products with unique specifications.

The Company designs its products with special attention to making them user-friendly, and constantly re-evaluates its products for the purpose of enhancing and improving them. The Company believes that these efforts, along with its willingness to adapt its products to the particular needs of its customers and its intensive efforts in customer and technical support, are factors that add to the competitiveness of its products.

Backlog

The Company’s consolidated backlog of firm orders shippable in the next twelve months was approximately $3,200,000 at December 31, 2013, compared to approximately $2,200,000 at December 31, 2012. It is anticipated that the majority of the backlog orders at December 31, 2013 will be filled during the current year. The stated backlog is not necessarily indicative of Company sales for any future period nor is a backlog any assurance that the Company will realize a profit from the orders.

Inventory, Supplies and Manufacturing

The Company purchases components, devices and subassemblies from a wide variety of sources. The Company’s inventory policy stresses maintaining substantial raw materials in order to lessen its dependency on third party suppliers and to improve its capacity to facilitate production. However, shortages or delays of supplies may, in the future, have a material adverse impact on the Company’s operations. For the years ended 2013 and 2012, no third-party supplier accounted for more than 11% and 8% of the Company’s total consolidated inventory purchases, respectively.

The Company is not party to any formal written contract regarding the deliveries of its supplies and components. It generally purchases such items pursuant to written purchase orders of both the individual and blanket variety. Blanket purchase orders usually cover the purchase of a larger amount of items at fixed prices for delivery and payment on specific dates.

The Company primarily produces its products by final and some intermediate assembly, calibration and testing. Testing of products is generally accomplished at the end of the manufacturing process and is performed in-house as are all quality control processes. The Company utilizes modern equipment for the design, engineering, manufacture, assembly and testing of its products.

Warranty and Service

The Company typically provides one-year warranties on its instrument products covering both parts and labor. The Company, at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance procedures have been followed by its customers. Repairs that are necessitated by misuse of such products or are required outside the warranty period are not covered by the Company’s warranty.

In cases of defective products, the customer typically returns them to a Company facility. The Company’s service personnel replace or repair the defective items and ship them back to the customer. Generally, all servicing is done at the Company’s plants, and the Company charges its customers a fee for those service items that are not covered by warranty. The Company’s Noisecom and Microlab/FXR divisions typically don’t offer their customers any formal written service contracts. However, the Company’s Boonton division does offer its customers’ formal written service contracts for a fee.

Product Liability Coverage

The testing of electronic communications equipment and the accurate transmission of information entail a risk of product liability by customers and others. Claims may be asserted against the Company by end-users of any of the Company’s products.

The Company maintains product liability insurance coverage and no claims have been asserted for product liability due to a defective or malfunctioning device. However, it is possible that the Company may be subject to such claims in the future and corresponding litigation should one or more of its products fail to perform or meet certain minimum specifications.

Intellectual Property

Proprietary information and know-how are important to the Company’s commercial success. The trademarks “Boonton” and “Noise Com” are registered in the United States Patent and Trademark Office. There can be no assurance that others will not either develop independently the same or similar information or obtain and use proprietary information of the Company. Certain key employees have signed confidentiality and non-competition agreements regarding the Company’s proprietary information.

The Company believes that its products do not infringe the proprietary rights of third parties. There can be no assurance, however, that third parties will not assert infringement claims in the future.

REGULATION

Environmental Protection

The Company’s operations are subject to various federal, state, local, and foreign environmental laws, ordinances and regulations that limit discharges into the environment, establish standards for the handling, generation, use, emission, release, discharge, treatment, storage and disposal of, or exposure to, hazardous materials, substances and waste, and require cleanup of contaminated soil and groundwater.

The New Jersey Department of Environmental Protection (the “NJDEP”) conducted an investigation in 1982 concerning disposal at a facility previously leased by the Company’s Boonton operations. The focus of the investigation involved certain materials formerly used by Boonton’s manufacturing operations at that site and the possible effect of such disposal on the aquifer underlying the property. The disposal practices and the use of the materials in question were discontinued in 1978. The Company has cooperated with the NJDEP investigation and has been diligently pursuing the matter in an attempt to resolve it in accordance with applicable NJDEP operating procedures. The above referenced activities were conducted by Boonton prior to the acquisition of that entity in 2000.

In 1982, the Company and the NJDEP agreed upon a plan to correct ground water contamination at the site, located in the township of Parsippany-Troy Hills, pursuant to which wells have been installed by the Company. The plan contemplates that the wells will be operated and that soil and water samples will be taken and analyzed until such time that contamination levels are satisfactory to the NJDEP. The Company is diligently pursuing efforts to satisfy the requirements of the original plan and receive a new determination from the NJDEP. Overall data from testing in March 2013 indicates the continuation of a decreasing concentration trend at the site. The overall decrease supports the absence of a continuing source impacting ground water. The Company believes that its current practice and plan of groundwater testing will continue until an official notification from NJDEP is obtained and the Company is released from further obligations.

Expenditures incurred by the Company during the year ended December 31, 2013 in connection with the site amounted to approximately $51,000. While management anticipates that the expenditures in connection with this site will not be substantial in future years, the Company could be subject to significant future liabilities and may incur significant future expenditures if further contaminants from Boonton’s testing are identified and the NJDEP requires additional remediation activities. Management is unable to estimate future remediation costs, if any, at this time. The Company will continue to be liable under the plan, in all future years, until such time as the NJDEP releases it from all obligations applicable thereto.

At this time, the Company believes that it is in material compliance with all environmental laws, does not anticipate any material expenditure to meet current or pending environmental requirements, and generally believes that its processes and products do not present any unusual environmental concerns. Besides the matter referred to above with the NJDEP, the Company is unaware of any existing, pending or threatened contingent liability that may have a material adverse affect on its ongoing business operations.

Workplace Safety

The Company’s operations are also governed by laws and regulations relating to workplace safety and worker health. The Company believes it is in material compliance with these laws and regulations and does not believe that future compliance with such laws and regulations will have a material adverse affect on its results of operations or financial condition. The Company also believes that it is in material compliance with all applicable labor regulations.

ITAR and Export Controls

The Company is subject to International Traffic in Arms Regulation, or ITAR. ITAR requires export licenses from the U.S. Department of State for products shipped outside the U.S. that have military or strategic applications.

The Company is also subject to the Export Administration Regulations, or EAR. The EAR regulates the export of certain “dual use” items and technologies and, in some instances, requires a license from the U.S. Department of Commerce.

Government Contracting Regulations

Because the Company has contracts with the federal government and its agencies, it is subject to audit from time to time of our compliance with government regulations by various agencies, including the Defense Contract Audit Agency, or DCAA. The DCAA reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. The DCAA has the right to perform audits on our incurred costs on all contracts on a yearly basis.

Other governmental agencies, including the Defense Securities Service and the Defense Logistics Agency, may also, from time to time, conduct inquiries or investigations regarding a broad range of our activities.

The Company’s principal products or services do not require any governmental approval, except for the requirement that it obtain export licenses for certain of its products.

Employees

As of March 28, 2014, the Company had 115 full-time employees, including its officers, 60 of whom are engaged in manufacturing and repair services, 11 in administration and financial control, 21 in engineering and research and development, and 23 in marketing and sales.

The Company considers its relationship with its employees to be satisfactory.

The design and manufacture of the Company’s products require substantial technical capabilities in many disparate disciplines, from mechanics and computer science to electronics and mathematics. While the Company believes that the capability and experience of its technical employees compares favorably with other similar manufacturers, there can be no assurance that it can retain existing employees or attract and hire the highly capable technical employees it may need in the future on terms deemed favorable to the Company.

Investor Information

The Company is subject to the informational requirements of the Securities Exchange Act of 1934 (“Exchange Act”). Therefore, it files periodic reports, proxy statements and other information with the Securities and Exchange Commission (“SEC”). Such reports, proxy statements and other information may be read and copied by visiting the Public Reference Room of the SEC at 100 F Street N.E., Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains an Internet site (http://www.sec.gov) that contains reports, proxy and information statements and other information regarding issuers that file electronically.

You can access financial and other information at the Company’s Investor Relations website. The address is www.wtcom.com. The Company makes available, free of charge, copies of its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after filing such material electronically or otherwise furnishing it to the SEC.

Our industry is highly competitive and if we are not able to successfully compete, we could lose market share and our revenues could decline.

We operate in industries characterized by aggressive competition, rapid technological change, evolving technology standards and short product life cycles. Current and prospective customers for our products evaluate our capabilities against the merits of our direct competitors. We compete primarily on the basis of technology and performance. For certain products, we also compete on price. Many of our competitors utilize similar technologies to ours and have substantially greater resources and expertise in financial, technical and marketing areas than we have. Our competitors may introduce products that are competitively priced, have increased performance or functionality or incorporate technological advances that we have not yet developed or implemented.

To remain competitive, we must continue to develop, market and sell new and enhanced products at competitive prices, which will require significant research and development expenditures. If we do not develop new and enhanced products or if we are not able to invest adequately in our research and development activities, our business, financial condition and results of operations could be negatively impacted.

Unless we keep pace with changing technologies, we could lose existing customers and fail to win new customers.

Our future success will depend upon our ability to develop and introduce a variety of new products and services and enhancements to these new products and services in order to address the changing needs of the marketplace. We may not be able to accurately predict which technologies customers will support. If we do not introduce new products, services and enhancements in a timely manner, if we fail to choose correctly among technical alternatives or if we fail to offer innovative products and services at competitive prices, customers may forego purchases of our products and services and purchase those of our competitors. We must make long-term investments and commit significant resources before knowing whether our predictions will eventually result in products that the market will accept. We must accurately forecast volumes, mix of products and configurations that meet customer requirements, and we may not succeed. If we do not succeed, we may be left with inventories of obsolete products or we may not have enough of some products available to meet customer demand, which could lead to reduced sales and higher expenses.

Ongoing recessionary economic conditions have adversely affected and may further adversely affect our business, results of operations, and financial condition.

General recessionary economic conditions have negatively impacted our business in the past and could further impact our business in the future if economic recovery is slow to occur. In addition to the potentially negative impact on our revenues, unstable economic conditions could also have a number of additional effects on our business, including insolvency of key suppliers or manufacturers resulting in product delays, inability of customers to obtain credit to finance purchases of our products, customer insolvencies, increased product returns, increased pricing pressures, restructuring expenses and associated diversion of management’s attention, excess inventory and increased difficulty in our accurately forecasting product demand and planning future business activities. If macro-economic concerns were to worsen, credit markets could begin to tighten once again. In turn, our customers could experience heightened financial difficulties and, as a result, could modify, delay or cancel plans to purchase our products or services, which could cause our sales to decline, or become unable to make payment to us for amounts due and owing. If the economy or markets into which we sell our products are slow to recover, our business, financial condition and results of operations could be materially and adversely affected.

The cyclicality of our end user markets could harm our financial results.

Many of the end markets we serve, including but not limited to the commercial wireless market, have historically been cyclical and have experienced periodic downturns. The factors leading to and the severity and length of a downturn are very difficult to predict and there can be no assurance that we will appropriately

anticipate changes in the underlying end markets we serve or that any increased levels of business activity will continue as a trend into the future. If we fail to anticipate changes in the end markets we serve, our business, results of operations and financial condition could be materially adversely affected.

Dependence on contract manufacturing and outsourcing other portions of our supply chain may adversely affect our ability to bring products to market and damage our reputation.

As part of our efforts to streamline operations and to cut costs, we outsource aspects of our manufacturing processes and other functions and continue to evaluate additional outsourcing. If our contract manufacturers or other outsourcers fail to perform their obligations in a timely manner or at satisfactory quality levels, our ability to bring products to market and our reputation could suffer. For example, during a market upturn, our contract manufacturers may be unable to meet our demand requirements, which may preclude us from fulfilling our customers’ orders on a timely basis. The ability of these manufacturers to perform is largely outside of our control. Additionally, changing or replacing our contract manufacturers or other outsourcers could cause disruptions or delays.

If our products do not perform as promised, we could experience increased costs, lower margins and harm to our reputation.

The failure of our products to perform as promised could result in increased costs, lower margins and harm to our reputation. We may not be able to anticipate all of the possible performance or reliability problems that could arise with our existing or new products, which could result in significant product liability or warranty claims. In addition, any defects found in our products could result in a loss of sales or market share, failure to achieve market acceptance, injury to our reputation, indemnification claims, litigation, increased insurance costs and increased service costs, any of which could discourage customers from purchasing our products and materially harm our business.

The testing of electronic communications equipment and the accurate transmission of information entail a risk of product liability claims being asserted by customers and third parties.

Claims may be asserted against us by end-users of any of our products for liability due to a defective or malfunctioning device made by us, and we may be subject to corresponding litigation should one or more of our products fail to perform or meet certain minimum requirements. Such a claim and corresponding litigation could result in substantial costs, diversion of resources and management attention, termination of customer contracts and harm to our reputation.

If we fail to adequately manage our resources, it could have a severe negative impact on our financial results or stock price.

We could be subject to fluctuations in technology spending by existing and potential customers. Accordingly, we will have to actively manage expenses in a rapidly changing economic environment. This could require reducing costs during economic downturns and selectively growing in periods of economic expansion. If we do not properly manage our resources in response to these conditions, our results of operations could be negatively impacted.

We are subject to various governmental regulations, compliance with which may cause us to incur significant expenses, and if we fail to maintain satisfactory compliance with certain regulations, we may be forced to recall products and cease their distribution, and we could be subject to civil or criminal penalties.

Our businesses are subject to various significant international, federal, state and local regulations, including but not limited to health and safety, packaging, product content, labor and import/export regulations. These regulations are complex, change frequently and have tended to become more stringent over time. We may be

required to incur significant expenses to comply with these regulations or to remedy violations of these regulations. Any failure by us to comply with applicable government regulations could also result in cessation of our operations or portions of our operations, product recalls or impositions of fines and restrictions on our ability to carry on or expand our operations.

We are subject to laws and regulations governing government contracts, and failure to address these laws and regulations or comply with such government contracts could harm our business by leading to a reduction in revenue associated with these customers.

We have agreements relating to the sale of our products to government entities and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the U.S. government. The laws governing government contracts differ from the laws governing private contracts. For example, many government contracts contain pricing terms and conditions that are not applicable to private contracts. We are also subject to investigation for compliance with the regulations governing government contracts. A failure to comply with these regulations might result in suspension of these contracts, or administrative penalties.

Shortages or delays of supplies for component parts may adversely affect our operating results until alternate sources can be developed.

Our operations are dependent on the ability of suppliers to deliver quality components, devices and subassemblies in time to meet critical manufacturing and distribution schedules. If we experience any constrained supply of any such component parts, such constraints, if persistent, may adversely affect operating results until alternate sourcing can be developed. There may be an increased risk of supplier constraints in periods where we are increasing production volume to meet customer demands. Volatility in the prices of these component parts, an inability to secure enough components at reasonable prices to build new products in a timely manner in the quantities and configurations demanded or, conversely, a temporary oversupply of these parts, could adversely affect our future operating results.

We could be subject to significant costs related to environmental contamination from past operations, and environmental contamination caused by ongoing operations could subject us to substantial liabilities in the future.

The Company’s operations are subject to various federal, state, local, and foreign environmental laws, ordinances and regulations that limit discharges into the environment, establish standards for the handling, generation, use, emission, release, discharge, treatment, storage and disposal of, or exposure to, hazardous materials, substances and waste, and require cleanup of contaminated soil and groundwater.

The New Jersey Department of Environmental Protection (the “NJDEP”) conducted an investigation in 1982 concerning disposal at a facility previously leased by the Company’s Boonton operations. The focus of the investigation involved certain materials formerly used by Boonton’s manufacturing operations at that site and the possible effect of such disposal on the aquifer underlying the property. The disposal practices and the use of the materials in question were discontinued in 1978. The Company has cooperated with the NJDEP investigation and has been diligently pursuing the matter in an attempt to resolve it in accordance with applicable NJDEP operating procedures. The above referenced activities were conducted by Boonton prior to the acquisition of that entity in 2000.

In 1982, the Company and the NJDEP agreed upon a plan to correct ground water contamination at the site, located in the township of Parsippany-Troy Hills, pursuant to which wells have been installed by the Company. The plan contemplates that the wells will be operated and that soil and water samples will be taken and analyzed until such time that contamination levels are satisfactory to the NJDEP. The Company is diligently pursuing efforts to satisfy the requirements of the original plan and receive a new determination from the NJDEP. Overall data from testing in March 2013 indicates the continuation of a decreasing concentration trend at the site. The overall decrease supports the absence of a continuing source impacting ground water. The Company believes that its current practice and plan of groundwater testing will continue until an official notification from NJDEP is obtained and the Company is released from further obligations.

Expenditures incurred by the Company during the year ended December 31, 2013 in connection with the site amounted to approximately $51,000. While management anticipates that the expenditures in connection with this site will not be substantial in future years, the Company could be subject to significant future liabilities and may incur significant future expenditures if further contaminants from Boonton’s testing are identified and the NJDEP requires additional remediation activities. Management is unable to estimate future remediation costs, if any, at this time. The Company will continue to be liable under the plan, in all future years, until such time as the NJDEP releases it from all obligations applicable thereto.

At this time, the Company believes that it is in material compliance with all environmental laws, does not anticipate any material expenditure to meet current or pending environmental requirements, and generally believes that its processes and products do not present any unusual environmental concerns. Besides the matter referred to above with the NJDEP, the Company is unaware of any existing, pending or threatened contingent liability that may have a material adverse affect on its ongoing business operations.

Certain of our products and international sales may be subject to ITAR, EAR, Foreign Corrupt Practices Act and other U.S. and foreign government laws, regulations, policies and practices, which may adversely affect our business, results of operations and financial condition.

Our international sales, for which we also use foreign representatives and consultants, are subject to U.S. laws, regulations and policies, including the ITAR and the Foreign Corrupt Practices Act and other export laws and regulations, as well as foreign government laws, regulations and procurement policies and practices which may differ from the U.S. Government regulations in this regard. The ITAR requires export licenses from the U.S. Department of State for products shipped outside the U.S. that have military or strategic applications.

Compliance with the directives of the U.S. Department of State may result in substantial legal and other expenses and the diversion of management time. In the event that a determination is made that we or any entity we have acquired has violated the ITAR with respect to any matters, we may be subject to substantial monetary penalties that we are unable to quantify at this time, and/or suspension or revocation of our export privileges and criminal sanctions, which may have a material adverse effect on our business, results of operations and financial condition.

We are also subject to the EAR. The EAR regulates the export of certain “dual use” items and technologies and, in some instances, requires a license from the U.S. Department of Commerce. We can give no assurance that under either the ITAR or the EAR we will continue to be successful in obtaining the necessary licenses and authorizations or that certain sales will not be prevented or delayed.

We are also subject to, and must comply with, the U. S. Foreign Corrupt Practices Act, or the FCPA, and similar world-wide anti-corruption laws, including the U.K. Bribery Act of 2010. These acts generally prohibit both us and our third party intermediaries from making improper payments to foreign officials for the purpose of acquiring or retaining business or otherwise obtaining favorable treatment. We are required as well to maintain adequate record-keeping and internal accounting practices to fully and accurately reflect our transactions. We have formulated and implemented strict diligence, training and reporting programs and practices that mandate and are intended to ensure compliance with these anti-corruption laws. We operate in many parts of the world that have experienced government corruption to some degree, however, and, in certain circumstances, the FCPA and our programs and policies may conflict with local customs and practices. If we or our any of our local intermediaries have failed to comply with the requirements of the FCPA, governmental authorities in the United States could seek to impose severe criminal and civil penalties. The assertion of violations of the FCPA or other anti-corruption laws could disrupt our business and, if proven, have a material adverse effect on our results of operations and financial condition.

The loss of key personnel could adversely affect our ability to remain competitive.

We believe that the continued service of our executive officers will be important to our future growth and competitiveness. However, other than the severance agreements we entered into with Mr. Genova, Chief Executive Officer, Mr. Debold, Vice President of Global Sales and Marketing, and Mr. Censullo, Chief Financial Officer, we currently do not have any employment agreements with any of our executive officers. Although we have severance agreements with Messrs. Genova, Debold and Censullo, we cannot provide assurance that any named executive

officer, or any of our other executive officers, will remain employed by us. Moreover, the design and manufacture of our products require substantial technical capabilities in many disparate disciplines, from engineering, mechanics and computer science to electronics and mathematics. We believe that the continued employment of key members of our technical and sales staffs will be important to us but, as with our executive officers, we cannot assure you that they will remain employed by us.

Third parties could claim that we are infringing on their intellectual property rights which could result in substantial costs, diversion of significant managerial resources and significant harm to our reputation.

The industries in which our company operates are characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement. From time to time, third parties may assert patent, copyright, trademark and other intellectual property rights to technologies in various jurisdictions that are important to our business. A successful claim of infringement against us could result in our being required to pay significant damages, enter into costly license agreements, or stop the sale of certain products, which could adversely affect our net sales, gross margins and expenses and harm our future prospects.

We use specialized technologies and know-how to design, develop and manufacture our products. Our inability to protect our intellectual property could hurt our competitive position, harm our reputation and adversely affect our results of operations.

We believe that our intellectual property, including its methodologies, is critical to our success and competitive position. We rely on a combination of U.S. and foreign patent, copyright, trademark and trade secret laws, as well as confidentiality agreements to establish and protect our proprietary rights. If we are unable to protect our intellectual property against unauthorized use by third parties, our reputation among existing and potential customers could be damaged and our competitive position adversely affected.

Attempts may be made to copy aspects of our products or to obtain and use information that we regard as proprietary. Accordingly, we may not be able to prevent misappropriation of our technology or deter others from developing similar technology. Our strategies to deter misappropriation could be undermined if:

If these risks materialize, we could be required to spend significant amounts to defend our rights and divert critical managerial resources. In addition, our proprietary methodologies may decline in value or our rights to them may become unenforceable. If any of the foregoing were to occur, our business could be materially adversely affected.

Our business and operations could suffer in the event of security breaches.

Attempts by others to gain unauthorized access to information technology systems are becoming more sophisticated and are sometimes successful. These attempts, which might be related to industrial or other espionage, include covertly introducing malware to our computers and networks and impersonating authorized users, among others. We seek to detect and investigate all security incidents and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. The theft, unauthorized use or publication of our intellectual property and/or confidential business information could harm our competitive position, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. To the extent that any security breach results in inappropriate disclosure of

our customers’ or licensees’ confidential information, we may incur liability as a result. In addition, we may be required to devote additional resources to the security of our information technology systems.

We rely on our information technology systems to manage numerous aspects of our business and a disruption of these systems could adversely affect our business.

Our information technology, or IT, systems are an integral part of our business. We depend on our IT systems for scheduling, sales order entry, purchasing, materials management, accounting, and production functions. Our IT systems also allow us to ship products to our customers on a timely basis, maintain cost-effective operations and provide a high level of customer service. Some of our systems are not fully redundant, and our disaster recovery planning does not account for all eventualities. A serious disruption to our IT systems could significantly limit our ability to manage and operate our business efficiently, which in turn could have a material adverse effect on our business, results of operations and financial condition.

The success of our ability to grow sales and develop relationships in Europe and Asia may be limited by risks related to conducting business in European and Asian markets.

Part of our strategy is to increase sales and build our relationships in European and Asian markets. Risks inherent in marketing, selling and developing relationships in European and Asian markets include those associated with:

In addition, European and Asian intellectual property laws are different than and may not protect our proprietary rights to the same extent as do U.S. intellectual property laws, and we will have to ensure that our intellectual property is adequately protected in foreign jurisdictions and in the United States. If we do not adequately protect our intellectual property rights, competitors could use our proprietary technologies in non-protected jurisdictions and put us at a competitive disadvantage.

Environmental and other disasters, such as flooding, large earthquakes, hurricanes, volcanic eruptions or nuclear or other disasters, or a combination thereof, may negatively impact our business.

Although we manufacture our products in New Jersey, we both source and ship our products globally. Environmental and other disasters may cause disruption to our supply chain or impede our ability to ship product to certain regions of the world. However, there can be no assurance that environmental and/or other such natural disasters will not have an adverse impact on our business in the future.

We are exposed to risks associated with acquisitions, investments and divestitures.

We have made, and may in the future make, acquisitions of, or significant investments in, businesses with complementary products, services and/or technologies. Acquisitions and investments involve numerous risks, including, but not limited to:

The integration of acquisitions may make the completion and integration of subsequent acquisitions more difficult. However, if we fail to identify and complete these transactions, we may be required to expend resources to internally develop products and technology or may be at a competitive disadvantage or may be adversely affected by negative market perceptions, which may have a material adverse effect on our business, results of operations and financial condition.

We may be required to finance future acquisitions and investments through a combination of borrowings, proceeds from equity or debt offerings and the use of cash, cash equivalents and short term investments.

With respect to divestitures, we may divest businesses that do not meet our strategic objectives, or do not meet our growth or profitability targets and may not be able to complete proposed divestitures on terms commercially favorable to us.

Mergers, acquisitions and investments are inherently risky and the inability to effectively manage these risks could materially and adversely affect our business, financial condition and results of operations.

Investcorp Technology Ventures, L.P. owns a substantial amount of our Common Stock.

Investcorp Technology Ventures, L.P., beneficially owns approximately 27% of the outstanding shares of our common stock as of March 28, 2014. Such stockholder has significant influence over the outcome of all matters submitted to stockholders for approval, including the election of directors. Consequently, this stockholder exercises substantial influence over all major decisions, including major corporate actions such as mergers and other business combinations or transactions which could result in or prevent a change of control of the Company. Accordingly, other stockholders’ abilities to influence us through voting their shares may be limited or the market price of our shares may be adversely affected.

Our stock price is volatile and the trading volume in our common stock is less than that of other larger companies in the wireless and advanced communications industries.

The market price of our Common Stock has experienced significant volatility and may continue to be subject to rapid swings in the future. From January 1, 2012 to March 19, 2014, the trading prices of our stock have ranged from $1.01 to $3.78 per share. There are several factors which could affect the price of our Common Stock, including some of which are announcements of technological innovations for new commercial products by us or our competitors, developments concerning propriety rights, new or revised governmental regulation or general conditions in the market for our products, and the entrance of additional competitors into our markets.

Although our Common Stock is listed for trading on the NYSE MKT, the trading volume in our Common Stock is less than that of other, larger companies in the wireless and advanced communications industries. Traditionally, the trading volume of our Common Stock has been limited. For example, for the 30 trading days

ending on February 28, 2014, the average daily trading volume was approximately 187,000 shares per day and ranged from between approximately 30,000 shares per day and approximately 495,000 shares per day. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing buyers and sellers of our Common Stock at any given time. Because of our limited trading volume, holders of our Common Stock may not be able to sell quickly any significant number of such shares, and any attempted sales of a large number of our shares will likely have a material adverse impact on the price of our Common Stock.

If securities or industry analysts do not publish research or reports about our business or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline

The trading market for our Common Stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, products or stock performance, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, the unpredictability of our financial results likely reduces the certainty, and therefore reliability, of the forecasts by securities or industry analysts of our future financial results, adding to the potential volatility of our stock price.

The inability to maintain adequate levels of liquidity may have an adverse affect on the working capital of the Company.

The Company believes that its financial resources from working capital provided by operations are adequate to meet its current needs. However, should current global economic conditions deteriorate, additional working capital financing may be required which may be difficult to obtain due to restrictive credit markets.

New Jersey corporate law may delay or prevent a transaction that stockholders would view as favorable.

We are subject to the New Jersey Shareholders’ Protection Act, which could delay or prevent a change of control of us.

The Company is subject to compliance with the policies & procedures of the NYSE MKT with respect to continued listing on the stock exchange.

In considering whether a security warrants continued trading and/or listing on the NYSE MKT Exchange, many factors are taken into account, such as the degree of investor interest in the company, its prospects for growth, the reputation of its management, the degree of commercial acceptance of its products, and whether its securities have suitable characteristics for auction market trading. Thus, any developments which substantially reduce the size of a company, the nature and scope of its operations, the value or amount of its securities available for the market, or the number of holders of its securities, may occasion a review of continued listing by the Exchange. Moreover, events such as the sale, destruction, loss or abandonment of a substantial portion of its business, the inability to continue its business, steps towards liquidation, or repurchase or redemption of its securities, may also give rise to such a review.

We incur significant costs as a result of operating as a public company, and our management devotes substantial time to compliance initiatives.

We have incurred and will continue to incur significant legal, accounting and other expenses as a public company, including costs resulting from public company reporting obligations under the Exchange Act and regulations regarding corporate governance practices. The listing requirements of the NYSE MKT require that we satisfy certain corporate governance requirements relating to director independence, distributing annual and interim reports, stockholder meetings, approvals and voting, soliciting proxies, conflicts of interest and a code of conduct. Our management and other personnel will need to devote a substantial amount of time to all of these requirements. Moreover, the reporting requirements, rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. These reporting requirements, rules and regulations, coupled with the increase in potential litigation exposure associated with being a public company, could make it more difficult for us to attract and retain qualified persons to serve on our board of directors or board committees or to serve as executive officers.

None.

The Company leases a 45,700 square foot facility located in Hanover Township, Parsippany, New Jersey, which is currently being used as its principal corporate headquarters and manufacturing plant. On February 25, 2014, the Company entered into an agreement to extend the building lease term for an additional six months through March 31, 2015. The lease term can be renewed at the Company’s option for one five-year period at fair market value to be determined at term expiration. The current minimum monthly base rent payment remains at approximately $29,000.

The Company owned a 44,000 square foot facility located in Mahwah, New Jersey (the “Mahwah Building”) which was leased to an unrelated third party. On July 26, 2012, the tenant exercised its exclusive option to purchase the Mahwah Building and, on August 1, 2013, the Company closed on the sale.

Reference is made to the discussion in Item 1 above regarding an investigation by the NJDEP concerning certain discontinued practices of the Company and their effect on the soil and ground water at a certain facility formerly occupied by the Company. No administrative or judicial proceedings have been commenced in connection with such investigation. The owner of the Parsippany-Troy Hills facility has previously notified the Company, that if the investigation proves to interfere with the sale of the property, it may seek to hold the Company liable for any resulting damages. Since May 1983, the owner has been on notice of this problem and has failed to institute any legal proceedings with respect thereto. While this does not bar the owner from instituting a suit, it is the opinion of the Company’s legal counsel that it is unlikely that the owner would prevail on any claim. The above referenced activity was conducted by Boonton prior to the acquisition of that entity in 2000. There are no other material legal proceedings known to the Company.

Not applicable.

Introduction

Wireless Telecom Group, Inc., and its operating subsidiaries, (collectively, “we”, “us” or the “Company”), develop, manufacture and market a wide variety of electronic noise sources, electronic testing and measuring instruments including power meters, voltmeters and modulation meters and high-power passive microwave components for wireless products. The Company’s products have historically been primarily used to test the performance and capability of cellular/PCS and satellite communication systems and to measure the power of RF and microwave systems. Other applications include radio, radar, wireless local area network (WLAN) and digital television.

The Company discloses its operations in two reportable segments: (1) network solutions and (2) test and measurement. The network solutions segment is comprised primarily of the operations of Microlab. The test and measurement segment is comprised primarily of the operations of Boonton and Noisecom. Additional financial information on the Company’s reportable segments for each of the last two years is included in Note 7 to the Company’s consolidated financial statements included in Item 8 herein.

The financial information presented herein includes: (i) Consolidated Balance Sheets as of December 31, 2013 and 2012 (ii) Consolidated Statements of Operations for the years ended December 31, 2013 and 2012 (iii) Consolidated Statement of Changes in Shareholders’ Equity for the years ended December 31, 2013 and 2012; and (iv) Consolidated Statements of Cash Flows for the years ended December 31, 2013 and 2012.

Forward-Looking Statements

The statements contained in this Annual Report on Form 10-K that are not historical facts, including, without limitation, the statements under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may be identified by, among other things, the use of forward-looking terminology such as “believes,” “expects,” “intends,” “plans,” “may,” “will,” “should,” “anticipates” or “continues” or the negative thereof of other variations thereon or comparable terminology, or by discussions of strategy that involve risks and uncertainties. These statements are based on the Company’s current expectations of future events and are subject to a number of risks and uncertainties that may cause the Company’s actual results to differ materially from those described in the forward-looking statements. These risks and uncertainties include continued ability to maintain positive cash flow from results of operations, continued evaluation of goodwill for impairment and the Company’s development and production of competitive technologies in our market sector, among others. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. These risks and uncertainties are disclosed from time to time in the Company’s filings with the Securities and Exchange Commission, the Company’s press releases and in oral statements made by or with the approval of authorized personnel. The Company assumes no obligation to update any forward-looking statements as a result of new information or future events or developments.

Critical Accounting Policies

Estimates and assumptions

Management’s discussion and analysis of the financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with accounting principles generally

accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses for each period. The following represents a summary of the Company’s critical accounting policies, defined as those policies that the Company believes are: (a) the most important to the portrayal of our financial condition and results of operations, and (b) that require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain. Estimates and assumptions are made by management to assess the overall likelihood that an accounting estimate or assumption may require adjustment. Management assumptions have been reasonably accurate in the past, and future estimates or assumptions are likely to be calculated on the same basis.

Stock-based compensation

The Company follows the provisions of Accounting Standards Codification (ASC) 718, “Share-Based Payment” which requires that compensation expense be recognized based on the fair value of the stock awards less estimated forfeitures. The fair value of the stock awards is equal to the fair value of the Company’s stock on the date of grant. The fair value of options at the date of grant was estimated using the Black-Scholes option pricing model. When options are granted, the Company takes into consideration guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using weekly price observations over an observation period that approximates the expected life of the options. The risk-free rate is based on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life. The estimated forfeiture rate included in the option valuation is based on our past history of forfeitures. Due to the limited amount of forfeitures in the past, the Company’s estimated forfeiture rate has been zero.

Management estimates are necessary in determining compensation expense for stock options with performance-based vesting criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions are determined to be probable of occurring through the date the applicable conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are considered probable of being met, if ever. Management evaluates whether performance conditions are probable of occurring on a quarterly basis.

Revenue recognition

Revenue from product shipments, including shipping and handling fees, is recognized once delivery has occurred, provided that persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. Sales to international distributors are recognized in the same manner. If title does not pass until the product reaches the customer’s delivery site, then revenue recognition is deferred until that time. There are no formal sales incentives offered to any of the Company’s customers. Volume discounts may be offered from time to time to customers purchasing large quantities on a per transaction basis. There are no special post shipment obligations or acceptance provisions that exist with any sales arrangements.

Inventories

Raw material inventories are stated at the lower of cost (first-in, first-out method) or market. Finished goods and work-in-process are valued at average cost of production, which includes material, labor and manufacturing expenses.

Allowances for doubtful accounts

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. A key consideration in estimating the allowance for doubtful accounts has been, and will continue to be, our customer’s payment history and aging of its accounts receivable balance.

Income taxes

The Company records deferred taxes in accordance with ASC 740, “Accounting for Income Taxes”. This ASC requires recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be realized. The Company periodically assesses the value of its deferred tax asset and determines the necessity for a valuation allowance. The Company evaluates which portion, if any, will more likely than not be realized by offsetting future taxable income, taking into consideration any limitations that may exist on its use of its net operating loss carryforwards.

Uncertain tax position

Under ASC 740, the Company must recognize and disclose the tax benefit from an uncertain position only if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authority, based on the technical merits of the position. The tax benefits recognized in the financial statements attributable to such position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon the ultimate resolution of the position.

The Company has analyzed its filing positions in all of the federal and state jurisdictions where it is required to file income tax returns. As of December 31, 2013 and 2012, the Company has identified its federal tax return and its state tax return in New Jersey as “major” tax jurisdictions, as defined, in which it is required to file income tax returns. Based on the evaluations noted above, the Company has concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements.

Based on a review of tax positions for all open years and contingencies as set out in the Company’s notes to the consolidated financial statements, no reserves for uncertain income tax positions have been recorded pursuant to ASC 740 during the years ended December 31, 2013 and 2012, and the Company does not anticipate that it is reasonably possible that any material increase or decrease in its unrecognized tax benefits will occur within twelve months.

Valuation of goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is not amortized but rather is reviewed for impairment at least annually, or more frequently if a triggering event occurs. Management first makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If, based on the qualitative assessment, the estimated fair value is well in excess of its carrying amount, management will not perform any quantitative assessment. If, however, the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management then performs a two-step goodwill impairment test. Under the first step, the fair value of the reporting unit is compared with its carrying value, and, if an indication of goodwill impairment exists for the reporting unit, the Company must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill as determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed.

The Company’s goodwill balance of $1,351,392 at December 31, 2013 and 2012 relates to one of the Company’s reporting units, Microlab. Management’s qualitative assessment performed in the fourth quarters of 2013 and 2012 did not indicate any impairment of Microlab’s goodwill as its fair value is estimated to be well in excess of its carrying value.

Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted cash flows resulting from the use of the assets and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold for sale is based on the fair value of the assets. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

Results of Operations

Year Ended December 31, 2013 Compared to 2012

Net consolidated sales for the year ended December 31, 2013 were $33,825,073 as compared to $29,594,544 for the year ended December 31, 2012, an increase of $4,230,529 or 14.3%. This increase was primarily the result of strong demand throughout 2013 for the Company’s network solutions products, particularly for use in DAS. In 2013, the Company experienced strong order activity in its network solutions segment due to commercial infrastructure development in support of ongoing DAS deployments and upgrades.

Net sales of the Company’s network solutions products for the year ended December 31, 2013 were $22,031,549 as compared to $14,334,095 for the year ended December 31, 2012, an increase of $7,697,454 or 53.7%. Net sales of network solutions products accounted for 65.1% and 48.4% of net consolidated sales for the years ended December 31, 2013 and 2012, respectively. The increase in sales during 2013 was primarily due to the Company’s growing participation in the DAS market through supply of its passive microwave components.

Net sales of the Company’s test and measurement products for the year ended December 31, 2013 were $11,793,524 as compared to $15,260,449 for the year ended December 31, 2012, a decrease of $3,466,925 or 22.7%. Net sales of test and measurement products accounted for 34.9% and 51.6% of net consolidated sales for the years ended December 31, 2013 and 2012, respectively. The decrease in sales for 2013 was primarily due to lower order volume during 2013 as a result of the Company’s completion of a large government contract in 2012 as well as decreased order flow from prime defense contractors due to sequestration.

The Company’s gross profit on consolidated net sales for the year ended December 31, 2013 was $16,128,350 or 47.7% as compared to $14,776,797 or 49.9% as reported in the previous year. Gross profit percentage was lower in 2013 compared to 2012 primarily due to a shift in segment revenue contribution and mix of product sold. The Company’s test and measurement segment typically provides for higher gross margins then the network solutions segment. Therefore, the decline in test and measurement sales, as a percentage of consolidated sales, resulted in a decrease in overall consolidated gross margins. Further compounding the effects of segment product mix on gross profit, test and measurement gross margins were lower in 2013 due to reduced test and measurement sales volumes as described in the preceding paragraph. As a result, overall blended gross profit margins declined by approximately 2% for 2013 as compared to 2012.

The Company’s products consist of several models with varying degrees of capabilities which can be customized to meet particular customer requirements. They may be incorporated directly into the electronic equipment concerned or may be stand-alone components or devices that are connected to, or used in conjunction with, such equipment from an external site, in the factory or in the field.

Prices of products range from approximately $100 to $100,000 per unit, with most sales occurring between approximately $2,000 and $35,000 per unit. The Company can experience variations in gross profit based upon the mix of these products sold, as well as variations due to revenue volume and economies of scale. The Company will continue to rigidly monitor costs associated with material acquisition, manufacturing and production.

Operating expenses for the year ended December 31, 2013 were $13,932,587 or 41.0% of consolidated net sales as compared to $12,019,179 or 40.6% of consolidated net sales for the year ended December 31, 2012. For the year ended December 31, 2013 as compared to the prior year, operating expenses increased by $1,913,408 or 15.9%. Operating expenses are higher in 2013 due to an increase in general and administrative expenses of $1,462,445, an increase in sales and marketing expenses of $254,923 and an increase in research and development expenses of $121,040. The increase in general and administrative expense is primarily due to an increase in corporate legal and consulting fees of $728,558 incurred in connection with the Company’s ongoing strategic review, an increase in non-cash stock-based compensation charges of $436,698 due to the acceleration of amortization related to performance-based stock options and amortization of restricted common stock, and an increase in bad debt expense of $166,542. Since the second quarter of 2012, the Company has been conducting a strategic review including capital allocation strategies which has required considerable involvement from the Company’s outside legal counsel and consulting firms. Although the Company’s strategic review is ongoing, management expects professional fees to decrease significantly going forward. Research and development expenses were higher in 2013 primarily due an increase in salaries in our network solutions segment of $275,672, partially offset by a decrease in salaries in our test and measurement segment of $110,854. Sales and marketing expenses were higher in 2013 primarily due to higher non-employee sales commissions in our network solutions segment of $426,309 and higher salaries expense of $392,159 due to the hiring of sales and marketing personnel in support of our network solutions segment, partially offset by lower non-employee sales commissions and lower salaries in our test and measurement segment in the amount of $268,347 and $229,591, respectively.

Interest expense, net of interest income derived from the Company’s cash investment account, decreased by $86,998 for the year ended December 31, 2013 as compared to the previous year. The decrease in interest expense is due to the repayment of the mortgage loan in August 2013 associated with the sale of the Mahwah Building. Substantially all of the Company’s cash is invested in money market funds.

Other income, net of other non-operating expense, increased by $260,360 for the year ended December 31, 2013 as compared to the previous year. The increase in other income was primarily due to a net realized gain on the sale of the Mahwah Building of $188,403 and the recording of a realized gain on the sale of an investment security of $161,500 in 2013, partially offset by lower rental income of $160,830 due to the sale of the Mahwah Building in 2013.

For the years ended December 31, 2013 and 2012, the Company realized a tax benefit of $1,275,659 and $389,763, respectively. For both years, the tax benefit was primarily due to a decrease in the Company’s deferred tax asset valuation allowance, partially offset by a provision for state income taxes. In 2013 and 2012, the Company analyzed its deferred tax asset on a quarterly basis and adjusted the deferred tax valuation allowance based on its projection of estimated taxable income. Based on this analysis, coupled with the Company’s history of generating taxable income and utilizing its domestic net operating loss carryforward, management determined it is more likely than not that the Company’s deferred tax assets will be fully realized. Accordingly, the associated valuation allowance on the Company’s net operating losses has been reduced to zero. The adjustments to the valuation allowance had a significant impact on the Company’s effective tax rates. The Company will continue to evaluate the need for a valuation allowance against this tax asset and will adjust the valuation allowance as deemed appropriate.

Net income was $3,842,200 or $0.16 per share on a diluted basis for the year ended December 31, 2013 as compared to net income of $3,170,801 or $0.13 per share on a diluted basis for the year ended December 31, 2012, an increase of $671,399 or $0.03 per diluted share. The increase was primarily due to the analysis discussed above.

Liquidity and Capital Resources

The Company’s working capital has increased by $2,689,432 to $29,205,447 at December 31, 2013, from $26,516,015 at December 31, 2012. At December 31, 2013 and 2012, respectively, the Company’s current ratio was 10.4 to 1 and 6.0 to 1.

The Company had cash and cash equivalents of $16,599,249 at December 31, 2013, compared to a balance of $12,969,513 at December 31, 2012. In 2013, the Company repurchased 174,741 shares of its outstanding common stock at a cost of $229,350. The Company believes its current level of cash is sufficient to fund the current operating, investing and financing activities.

The Company expects to realize tax benefits in future periods due to the available net operating loss carryforwards resulting from the disposition of a former wholly-owned subsidiary in 2010. Accordingly, future taxable income is expected to be offset by the utilization of operating loss carryforwards and as a result will increase the Company’s liquidity as cash needed to pay Federal income taxes will be substantially reduced. As of December 31, 2013, the remaining balance of the valuation allowance of $7,012,134 relates to the Company’s foreign net operating loss carryforwards which is unlikely to be realized in future periods.

Operating activities provided $3,497,090 in cash for the year ended December 31, 2013. For the year ended December 31, 2012, operating activities provided $2,179,280 in cash flows. For 2013, cash provided by operations was primarily due to income from operations, an increase in accounts payable, accrued expenses and other current liabilities,

a decrease in accounts receivable and a decrease in inventories, partially offset by an increase in prepaid expenses and other assets. For 2012, cash provided by operations was primarily due to income from operations and an increase in accounts payable, accrued expenses and other current liabilities, partially offset by increases in accounts receivable, inventory and prepaid expenses and other assets.

The Company has historically turned over its accounts receivable approximately every two months. This average collection period has been sufficient to provide the working capital and liquidity necessary to operate the Company.

On August 1, 2013, the Company closed on the sale of the Mahwah Building. Additionally, the Company repaid the existing mortgage payable on the building with the proceeds of the sale. As part of the terms of the sale, the Company was required to place $350,000 in escrow until certain conditions are met, as determined by the State of New Jersey. The terms of the mortgage required monthly payments of $23,750 applied to both principal and interest at the annual rate of 7.45%.

Net cash provided by investing activities for the year ended December 31, 2013 was $3,052,019. The source of this cash was due to proceeds from the sale of the Mahwah Building and proceeds from the sale of a non-marketable security, offset by capital expenditures. Net cash used for investing activities for the year ended December 31, 2012 was $447,900. The use of cash was for capital expenditures.

Financing activities used $2,919,373 in cash for the year ended December 31, 2013. The use of these funds was for the final payment on a mortgage note, the acquisition of treasury stock and periodic payments on an equipment lease. Financing activities used $851,649 in cash for the year ended December 31, 2012. The use of these funds was for the repurchase of treasury stock and periodic payments on the mortgage note for the Mahwah Building.

The Company maintains a line of credit with its investment bank. The credit facility provides borrowing availability of up to 100% of the Company’s money market account balance and 99% of the Company’s short-term investment securities and, under the terms and conditions of the loan agreement, is fully secured by said money fund account and any short-term investment holdings. Advances under the facility will bear interest at a variable rate equal to the London InterBank Offered Rate in effect at time of borrowing. Additionally, under the terms and conditions of the loan agreement, there is no annual fee and any amount outstanding under the loan facility may be paid at any time in whole or in part without penalty. As of December 31, 2013, the Company had no borrowings outstanding under the facility and approximately $4,500,000 of borrowing availability. Since the credit facility is based upon our current investment balance, borrowing availability has declined over time due to the Company’s funding of its stock repurchases. The Company has no current plans to borrow from this credit facility as it believes cash generated from operations will adequately meet near-term working capital requirements.

From time to time, the Company has pursued, and may continue to pursue, strategic opportunities including potential acquisitions, mergers, divestitures or other activities which may require the Company to use part or all of its cash reserves, enter into credit arrangements or issue shares of its common stock or other securities. The Company incurs costs as a result of such activities and such activities may affect the Company’s liquidity in future periods.

On August 1, 2013, the Company was awarded a contract with the Federal Aviation Administration to supply RF Peak Power Meters in support of the Common Route Surveillance Radar (“CARSR”) installations. The total order value of the product to be sold under the contract is approximately $1,100,000 with a considerable portion of the order, approximately $800,000, expected to be realized over fiscal year 2014. Additionally, on March 3, 2014, the Company received a significant order from one of its customers to supply its Low PIM Attenuators. The total order value of the product to be sold under the purchase order is approximately $1,800,000 with a majority of the revenue expected to be realized in 2014.

The Company believes that its financial resources from working capital provided by operations are adequate to meet its current needs. However, should current global economic conditions deteriorate, additional working capital funding may be required which may be difficult to obtain due to restrictive credit markets.

Off-Balance Sheet Arrangements

Other than contractual obligations incurred in the normal course of business, the Company does not have any off-balance sheet arrangements.

Inflation and Seasonality

The Company does not anticipate that inflation will significantly impact its business nor does it believe that its business is seasonal.

Recent Accounting Pronouncements Affecting the Company

In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. This ASU was effective for the Company beginning January 1, 2013. The adoption of this ASU did not have a material impact on its consolidated financial statements.

The Company does not believe there are any other recently issued, but not yet effective accounting pronouncements, if adopted, that would have a material effect on the accompanying consolidated financial statements.

Industry Risk

The electronic test and measurement industry is cyclical which can cause significant fluctuations in sales, gross profit margins and profits, from year to year. It is difficult to predict the timing of the changing cycles in the electronic test and measurement industry.

The response to this item is submitted in a separate section of this report. See the Consolidated Financial Statements and accompanying notes set forth below.

(a) Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, as of the end of the period covered by this report, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e)

and 15d-15(e) under the Securities Act of 1934. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be included in our SEC reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, relating to Wireless Telecom Group, Inc. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of the period covered by this report, our disclosure controls and procedures are effective.

(b) Management’s Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurances with respect to financial statement preparation and presentation. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2013, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in “Internal Control — Integrated Framework,” (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO 1992 criteria). Based on the assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2013.

This annual report does not include an attestation report of the Company’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s independent registered public accounting firm pursuant to the Dodd-Frank Wall Street and Consumer Protection Act, which exempts non-accelerated filers from the auditor attestation requirement of Section 404 (b) of the Sarbanes-Oxley Act.

(c) Changes in Internal Controls over Financial Reporting

In connection with the evaluation required by paragraph (d) of Rule 13a-15 under the Exchange Act, there was no change identified in our internal control over financial reporting that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

None.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

Wireless Telecom Group, Inc.

Parsippany, NJ

We have audited the accompanying consolidated balance sheets of Wireless Telecom Group, Inc. and Subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of operations, changes in shareholders’ 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 consolidated 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. We were not engaged to perform an audit of the Company’s 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 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 Wireless Telecom Group, Inc. and Subsidiaries at December 31, 2013 and 2012 and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

The accompanying notes are an integral part of these consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

Organization and Basis of Presentation:

Wireless Telecom Group, Inc. and Subsidiaries (the “Company”) develops and manufactures a wide variety of electronic noise sources, testing and measurement instruments and high-power, passive microwave components, which it sells to customers throughout the United States and worldwide through its foreign sales corporation and foreign distributors to commercial and government customers in the electronics industry. The consolidated financial statements include the accounts of Wireless Telecom Group, Inc., which operates one of its product lines under the trade name Noisecom, Inc. (“Noisecom”), and its wholly-owned subsidiaries, Boonton Electronics Corporation (“Boonton”), Microlab/FXR (“Microlab”), WTG Foreign Sales Corporation and NC Mahwah, Inc. All intercompany transactions are eliminated in consolidation.

The Company discloses its operations in two reportable segments, test and measurement and network solutions. The test and measurement segment is comprised primarily of the operations of Boonton and Noisecom. The network solutions segment is comprised primarily of the operations of Microlab.

Use of Estimates:

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which 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 financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The most significant estimates and assumptions include management’s analysis in support of realization of the Company’s deferred tax asset, accounting for performance-based stock options, inventory reserves and allowance for doubtful accounts.

Concentrations of Credit Risk and Fair Value:

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable.

The Company maintains significant cash investments primarily with two financial institutions, which at times may exceed federally insured limits. The Company performs periodic evaluations of the relative credit rating of these institutions as part of its investment strategy.

Concentrations of credit risk with respect to accounts receivable is diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographies. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. Credit evaluation is performed independent of the Company’s sales team to ensure segregation of duties.

One customer accounted for 11% of the Company’s total consolidated sales for each of the years ended December 31, 2013 and 2012. At December 31, 2013 and 2012, no customer represented 10% or more of the Company’s gross accounts receivable balance.

The carrying amounts of cash and cash equivalents, trade receivables, prepaid expenses and other current assets, accounts payable and accrued expenses and other current liabilities approximate fair value due to the short-term nature of these instruments.

At December 31, 2012, the fair value (estimated based upon expected cash outflows discounted at current market rates) and carrying value of the fixed rate mortgage amounted to $2,690,786 and $2,629,215, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

Cash and Cash Equivalents:

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist of operating and money market accounts.

The Company classifies investments as short-term investments if their original or remaining maturities are greater than three months and their remaining maturities are one year or less. As of December 31, 2013, substantially all of the Company’s investments consisted of cash and cash equivalents.

Accounts Receivable and allowance for doubtful accounts:

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The volatility of the industries the Company serves can cause certain of its customers to experience shortages of cash flows, which can impact their ability to make required payments. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Estimated allowances for doubtful accounts are reviewed periodically taking into account the customer’s recent payment history, the customer’s current financial statements and other information regarding the customer’s credit worthiness. Account balances are charged off against the allowance when it is determined the receivable will not be recovered.

Inventories:

Raw material inventories are stated at the lower of cost (first-in, first-out method) or market. Finished goods and work-in-process are valued at average cost of production, which includes material, labor and manufacturing expenses. Inventory carrying value is net of inventory reserves of $765,413 and $621,996 as of December 31, 2013 and 2012, respectively.

Inventories consist of:

Property, Plant and Equipment:

Property, plant and equipment are reflected at cost, less accumulated depreciation. Depreciation and amortization are provided on a straight-line basis over the following useful lives:

Leasehold improvements are amortized over the remaining term of the lease and reflect the estimated life of the improvements. Repairs and maintenance are charged to operations as incurred; renewals and betterments are capitalized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

Goodwill:

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is not amortized but rather is reviewed for impairment at least annually, or more frequently if a triggering event occurs. Management first makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If, based on the qualitative assessment, the estimated fair value is well in excess of its carrying amount, management will not perform any quantitative assessment. If, however, the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management then performs a two-step goodwill impairment test. Under the first step, the fair value of the reporting unit is compared with its carrying value, and, if an indication of goodwill impairment exists for the reporting unit, the Company must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill as determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed.

The Company’s goodwill balance of $1,351,392 at December 31, 2013 and 2012 relates to one of the Company’s reporting units, Microlab. Management’s qualitative assessment performed in the fourth quarters of 2013 and 2012 did not indicate any impairment of Microlab’s goodwill as its fair value is estimated to be well in excess of its carrying value.

Impairment of long-lived assets:

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted cash flows resulting from the use of the assets and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold for sale is based on the fair value of the assets. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

Revenue Recognition:

Revenue from product shipments, including shipping and handling fees, is recognized once delivery has occurred provided that persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. Sales to international distributors are recognized in the same manner. If title does not pass until the product reaches the customer’s delivery site, then recognition of revenue is deferred until that time. There are no formal sales incentives offered to any of the Company’s customers. Volume discounts may be offered from time to time to customers purchasing large quantities on a per transaction basis. There are no special post shipment obligations or acceptance provisions that exist with any sales arrangements.

Research and Development Costs:

Research and development costs are charged to operations when incurred. The amounts charged to operations for the years ended December 31, 2013 and 2012 were $2,645,070 and $2,524,030, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

Advertising Costs:

Advertising expenses are charged to operations during the year in which they are incurred and aggregated $302,269 and $326,431 for the years ended December 31, 2013 and 2012, respectively.

Stock-Based Compensation:

The Company follows the provisions of ASC 718, “Share-Based Payment” which requires that compensation expense be recognized, based on the fair value of the stock awards less estimated forfeitures. The fair value of the stock awards is equal to the fair value of the Company’s stock on the date of grant. The fair value of options at the date of grant was estimated using the Black-Scholes option pricing model. When performance-based options are granted, the Company takes into consideration guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using weekly price observations over an observation period that approximates the expected life of the options. The risk-free rate is based on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life. The estimated forfeiture rate included in the option valuation is based on our past history of forfeitures. Due to the limited amount of forfeitures in the past, the Company’s estimated forfeiture rate has been zero.

Management estimates are necessary in determining compensation expense for stock options with performance-based vesting criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions are determined to be probable of occurring through the implicit service period, which is the date the applicable conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are considered probable of being met, if ever. If the award is forfeited because the performance condition is not satisfied, previously recognized compensation cost is reversed. Management evaluates performance conditions on a quarterly basis.

Income Taxes:

The Company records deferred taxes in accordance with ASC 740, “Accounting for Income Taxes”. This ASC requires recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be realized. The Company periodically assesses the value of its deferred tax asset and determines the necessity for a valuation allowance.

The Company had historically analyzed its deferred tax asset on a quarterly basis and adjusted the deferred tax valuation allowance based on its rolling five-year projection of estimated taxable income, taking into consideration any limitations that may exist on its use of its net operating loss carryforwards. During the fourth quarter of 2013, the Company evaluated the realizability of its deferred tax asset and the need for a valuation allowance based upon the Company’s history of generating taxable income, analysis of expected future taxable income, as well as other factors deemed appropriate. As a result, management determined that the entire deferred tax asset is expected to be realized and accordingly has not provided a valuation allowance to its deferred tax asset on its domestic net operating losses.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

Under ASC 740, the Company must recognize and disclose the tax benefit from an uncertain position only if it is more-likely-than-not the tax position will be sustained on examination by the taxing authority, based on the technical merits of the position. The tax benefits recognized and disclosed in the financial statements attributable to such position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon the ultimate resolution of the position.

The Company has analyzed its filing positions in all of the federal and state jurisdictions where it is required to file income tax returns. As of December 31, 2013 and 2012, the Company has identified its federal tax return and its state tax return in New Jersey as “major” tax jurisdictions, as defined, in which it is required to file income tax returns. Based on the evaluations noted above, the Company has concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements.

Based on a review of tax positions for all open years and contingencies as set out in the Company’s notes to the consolidated financial statements, no reserves for uncertain income tax positions have been recorded pursuant to ASC 740 during the years ended December 31, 2013 and 2012, and the Company does not anticipate that it is reasonably possible that any material increase or decrease in its unrecognized tax benefits will occur within twelve months.

Income Per Common Share:

Basic income per share is calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted income per share is calculated by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period and, when dilutive, potential shares from stock options and warrants to purchase common stock, using the treasury stock method. In accordance with ASC 260, “Earnings Per Share”, the following table reconciles basic shares outstanding to fully diluted shares outstanding.

Common stock options are included in the diluted income (loss) per share calculation only when option exercise prices are lower than the average market price of the common shares for the period presented. The weighted average number of common stock options not included in diluted income (loss) per share, because the effects are anti-dilutive, was 2,481,748 and 1,904,792 for 2013 and 2012, respectively.

Subsequent events:

The Company has evaluated subsequent events and, except as described in Note 10, the Company has determined that there were no subsequent events or transactions requiring recognition or disclosure in the consolidated financial statements.

Recent Accounting Pronouncements Affecting the Company:

In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period.

On August 1, 2013, the Company closed on the sale of a property previously owned by the Company and located in Mahwah, New Jersey (the “Mahwah Building”) and repaid the existing mortgage loan payable on the building with the proceeds of the sale. As part of the terms of the sale, the Company was required to place $350,000 in escrow until certain conditions are met, as determined by the State of New Jersey. The Company expects the escrow amount to be released subsequent to the filing of its 2013 tax returns in mid-2014. The terms of the mortgage loan relating to the Mahwah Building required monthly payments of $23,750 applied to both principal and interest at the annual rate of 7.45%. As a result of the sale and the repayment of the mortgage loan, the Company recognized a gain of $188,403 and is no longer obligated to make any loan payments. At December 31, 2012, the Mahwah Building is included in Assets Held for Sale in the accompanying consolidated balance sheets at a carrying value of $3,179,002.

Included in the Company’s consolidated statement of operations, recorded as non-operating income, are certain income and expenses directly related to the Mahwah Building. The Company’s results of operations included rental income of $225,161 and $385,992 for the years ended December 31, 2013 and 2012, respectively. For the years ended December 31 2013 and 2012, the Company’s results of operations included mortgage interest expense of $115,103 and $201,842 and building depreciation expenses of $0 and $66,698, respectively.

Incentive Compensation Plan:

On June 13, 2012, our shareholders approved the Company’s 2012 Incentive Compensation Plan (the “2012 Plan”). The 2012 Plan replaced the Company’s Amended and Restated 2000 Stock Option Plan, as amended (the “Prior Plan”), under which no additional grants will be made. Under the 2012 Plan, the total number of shares of the Company’s common stock reserved and available for issuance under the 2012 Plan at any time is 2,000,000 shares, plus any shares subject to awards that have been issued under the Prior Plan that expire, are cancelled, or are terminated after June 13, 2012 without having been exercised in full and would have become available for subsequent grants under the Prior Plan. As of December 31, 2013, there were 746,304 shares available for issuance under the 2012 Plan. The 2012 Plan provides for the grant of Restricted Stock Awards, Non-Qualified Stock Options and Incentive Stock Options in compliance with the Internal Revenue Code of 1986, as amended, to employees, officers, directors, consultants and advisors of the Company who are expected to contribute to the Company’s future growth and success.

All service-based options granted have ten year terms and, from the date of grant, vest annually and become fully exercisable after a maximum of five years. Performance-based options granted have ten year terms and vest and become fully exercisable when determinable performance targets are achieved. Performance targets are agreed to, and approved by, the Company’s board of directors.

Under the Company’s 2012 Plan, options may be granted to purchase shares of the Company’s common stock exercisable at prices generally equal to or above the fair market value on the date of the grant.

Restricted common stock awards:

On August 19, 2013, the Board of Directors approved the grant of performance-based restricted stock awards to certain employees of the Company, including its officers. On August 19, 2013, the Company entered into restricted stock agreements pursuant to which certain employees of the Company were awarded, collectively, up to 100,000 shares of the Company’s common stock at $1.77 per share, which represents the closing price of the Company’s common stock on the date of grant.

Under the terms of the restricted stock agreements, the awards will fully vest and become exercisable on the date on which the Board shall have determined that specific revenue and earnings performance targets have been met, provided the employee remains in the employ of the Company at such time; provided, however, upon a Change in Control (as defined in the restricted stock agreements and the 2012 Plan), the restricted stock shall automatically vest as permitted by the 2012 Plan. As of December 31, 2013, the Company has not incurred expense relating to these performance-based stock awards as it is improbable that the performance targets will be achieved.

On June 12, 2013, certain members of the Company’s Board of Directors were each granted 20,000 shares of restricted common stock, 120,000 shares in total, at $1.51 per share, which represents the closing price of the Company’s common stock on the date of grant. These shares will vest on the date of the Company’s next annual meeting of shareholder’s to be held in June 2014, provided that the director’s service continues through the vesting date.

During the year ended December 31, 2012, the Company repurchased 23,334 shares of restricted common stock from its Chief Executive Officer for $26,834, or $1.15 per share which represented the trading price at the date of repurchase. In accordance with the terms of the 2012 Plan, the Compensation Committee of the Board of Directors authorized the Company to repurchase, upon vesting of the restricted stock, that certain number of shares necessary to allow such grantees to satisfy their personal tax liability associated with the vesting of such shares.

For the years ended December 31, 2013 and 2012, the Company recorded compensation expense related to restricted common stock in the amount of $155,268 and $112,432, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

As of December 31, 2013, the unearned compensation related to Company granted restricted common stock is $267,600 of which $90,600 will be amortized on a straight-line basis through the date of the Company’s next annual meeting to be held in June 2014, the vesting date. The remaining balance of $177,000 will begin to be amortized when it is determined that certain vesting conditions are probable of being achieved.

Performance-based stock option awards:

On August 19, 2013, the Board of Directors approved the grant of performance-based stock options to certain employees of the Company, including its officers. Accordingly, the Company entered into stock option agreements pursuant to which certain employees of the Company were awarded options to purchase, collectively, up to 950,000 shares of the Company’s common stock at an exercise price of $1.77 per share, which represents the closing price of the Company’s common stock on the date of grant.

Under the terms of the stock option agreements the options will fully vest and become exercisable on the date on which the Board shall have determined that specific revenue and earnings performance targets have been met, provided the employee remains in the employ of the Company at such time; provided, however, upon a Change in Control (as defined in the stock option agreements and the 2012 Plan), the options shall automatically accelerate and become fully exercisable as permitted by the 2012 Plan. As of December 31, 2013, the Company has not incurred expense relating to these performance-based stock options as it is improbable that the performance targets will be achieved.

A summary of performance-based stock option activity, and related information for the years ended December 31 2013 and 2012 follows:

The aggregate intrinsic value of performance-based stock options outstanding as of December 31, 2013 and 2012 was $1,896,250 and $416,150, respectively. The aggregate intrinsic value of performance-based stock options exercisable as of December 31, 2013 and 2012 was $1,563,750 and $0, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

For the years ended December 31, 2013 and 2012, the Company recorded compensation expense related to performance-based options in the amount of $590,794 and $196,932, respectively.

Management evaluates the likelihood of achieving certain vesting conditions with respect to performance-based stock awards on a quarterly basis. Since the end of 2011, the Company had been amortizing its performance-based options issued prior to 2013 on a straight-line basis through December 31, 2015, the expected implicit service period at the time, which resulted in annual compensation expense of $196,932. During the three-months ended September 30, 2013, management determined that the performance targets for those options granted prior to 2013 were likely to be met as of December 31, 2013. As a result, the Company accelerated the expensing of such options through December 31, 2013, the revised implicit service date. The impact of the accelerated expense on net income for the year ended December 31, 2013 was $393,862, or $0.02 per basic and diluted share. Additionally, due to the acceleration, this tranche of options has been fully amortized at December 31, 2013.

The aggregate grant date fair-value of performance-based options granted in 2013 was $867,683, or approximately $0.91 per share. The unearned compensation of $867,683 will not be recognized until management considers it probable that the respective performance conditions to be achievable.

In addition to its in-house sales staff, the Company uses various manufacturers’ representatives to sell its products. For the years ended December 31, 2013 and 2012, no representative accounted for more than 10% of total consolidated sales.

Regional Sales:

Net consolidated sales from operations by region were as follows:

Net sales are attributable to a geographic area based on the destination of the product shipment. The majority of shipments in the Americas are to customers located within the United States. For the years ended December 31, 2013 and 2012, sales in the United States amounted to $25,152,929 and $20,930,669, respectively. Shipments to the remaining regions presented above were largely concentrated in Germany (EMEA) and China (APAC). For the years ended December 31, 2013 and 2012, sales to Germany amounted to $1,330,645, or 30% of all shipments to the EMEA region, and $1,394,467, or 30% of all shipments to the EMEA region, respectively. Sales to China, for the years ended December 31, 2013 and 2012, amounted to $1,609,182, or 61% of all shipments to the APAC region, and $1,414,485, or 60% of all shipments to the APAC region, respectively. There were no other shipments significantly concentrated in one country.

Purchases:

For the years ended 2013 and 2012, no third-party supplier accounted for more than 11% and 8% of the Company’s total consolidated inventory purchases, respectively.

The Company has a 401(k) profit sharing plan covering all eligible U.S. employees. Company contributions to the plan for the years ended December 31, 2013 and 2012 amounted to $353,463 and $320,276, respectively.

The components of income tax expense (benefit) related to income from operations are as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

The following is a reconciliation of the maximum statutory federal tax rate to the Company’s effective tax relative to operations:

In 2013 and 2012, the difference between the statutory and the effective tax rate is primarily due to a change in valuation allowance on deferred taxes based upon management’s updated assumptions related to expected realizability of future taxable income.

The components of deferred income taxes are as follows:

The Company has a domestic net operating loss carryforward at December 31, 2013 of approximately $21,300,000 which expires in 2029. The Company also has a foreign net operating loss carryforward at December 31, 2013 of approximately $23,400,000 which has no expiration.

Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the appropriate tax jurisdictions in future years to obtain benefit from the reversal of net deductible temporary differences and from utilization of net operating losses. The Company’s valuation allowance of $7,012,134 at December 31, 2013, is associated with the Company’s foreign net operating loss carryforward from an inactive foreign entity which is unlikely to be realized in future periods. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are changed. As of December 31, 2013, management believes that is more likely than not that the Company will fully realize the benefits of its deferred tax assets associated with its domestic net operating loss carryforward.

The Company files income tax returns in its U.S. (federal and state of New Jersey) taxing jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal and state tax examinations in its major tax jurisdictions for periods before 2009.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

During the year ended December 31, 2013, the State of New Jersey conducted a field examination of one of the Company’s subsidiary tax returns (Boonton) for the years 2009 through 2012. The examination was completed in October 2013 and the State of New Jersey did not propose any significant adjustments to the Company’s tax positions. Additionally, the State of New Jersey is currently in the process of conducting a field examination of another of the Company’s subsidiary tax returns (Microlab) for the years 2009 through 2012. The Company expects the examination to be completed in mid 2014.

The Company does not have any significant unrecognized tax benefits and does not anticipate significant increase or decrease in unrecognized tax benefits within the next twelve months. Amounts recognized for income tax related interest and penalties as a component of the provision for income taxes are immaterial for the years ended December 31, 2013 and 2012.

Warranties:

The Company typically provides one-year warranties on all of its products covering both parts and labor. The Company, at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance procedures have been followed by its customers. Historically, warranty expense within the Company has been minimal.

Operating Leases:

The Company leases a 45,700 square foot facility located in Hanover Township, Parsippany, New Jersey, which is currently being used as its principal corporate headquarters and manufacturing plant. On February 25, 2014, the Company entered into an agreement to extend the building lease term for an additional six months through March 31, 2015. The lease can be renewed at the Company’s option for one five-year period at fair market value to be determined at term expiration. The current minimum monthly base rent payment remains at approximately $29,000.

The Company is also responsible for its proportionate share of the cost of utilities, repairs, taxes, and insurance. The future minimum lease payments are shown below:

Rent expense, inclusive of common area maintenance charges, for the years ended December 31, 2013 and 2012 was $463,160 and $466,461, respectively.

The Company leases certain equipment under operating lease arrangements. These operating leases expire in various years through 2018. All leases may be renewed at the end of their respective leasing periods. Future payments relative to continuing operations consist of the following at December 31, 2013:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Wireless Telecom Group, Inc.

In June 2013, the Company entered into a lease agreement for production test equipment. The agreement requires monthly payments in the amount of approximately $10,000 through June 2015. The net book value of the equipment was $179,399 at December 31, 2013.

Environmental Contingencies:

The New Jersey Department of Environmental Protection (the “NJDEP”) conducted an investigation in 1982 concerning disposal at a facility previously leased by the Company’s Boonton operations. The focus of the investigation involved certain materials formerly used by Boonton’s manufacturing operations at that site and the possible effect of such disposal on the aquifer underlying the property. The disposal practices and the use of the materials in question were discontinued in 1978. The Company has cooperated with the NJDEP investigation and has been diligently pursuing the matter in an attempt to resolve it in accordance with applicable NJDEP operating procedures. The above referenced activities were conducted by Boonton prior to the acquisition of that entity in 2000.

In 1982, the Company and the NJDEP agreed upon a plan to correct ground water contamination at the site, located in the township of Parsippany-Troy Hills, pursuant to which wells have been installed by the Company. The plan contemplates that the wells will be operated and that soil and water samples will be taken and analyzed until such time that contamination levels are satisfactory to the NJDEP. The Company is diligently pursuing efforts to satisfy the requirements of the original plan and receive a new determination from the NJDEP. Overall data from testing in March 2013 indicates the continuation of a decreasing concentration trend at the site. The overall decrease supports the absence of a continuing source impacting ground water. The Company believes that its current practice and plan of groundwater testing will continue until an official notification from NJDEP is obtained and the Company is released from further obligations.

Expenditures incurred by the Company during the year ended December 31, 2013 in connection with the site amounted to approximately $51,000. While management anticipates that the expenditures in connection with this site will not be substantial in future years, the Company could be subject to significant future liabilities and may incur significant future expenditures if further contaminants from Boonton’s testing are identified and the NJDEP requires additional remediation activities. Management is unable to estimate future remediation costs, if any, at this time. The Company will continue to be liable under the plan, in all future years, until such time as the NJDEP releases it from all obligations applicable thereto.

At this time, the Company believes that it is in material compliance with all environmental laws, does not anticipate any material expenditure to meet current or pending environmental requirements, and generally believes that its processes and products do not present any unusual environmental concerns. Besides the matter referred to above with the NJDEP, the Company is unaware of any existing, pending or threatened contingent liability that may have a material adverse affect on its ongoing business operations.

Line of Credit:

The Company maintains a line of credit with its investment bank. The credit facility provides borrowing availability of up to 100% of the Company’s money market account balance and 99% of the Company’s short-term investment securities and, under the terms and conditions of the loan agreement, is fully secured by said money fund account and any short-term investment holdings. Advances under the facility will bear interest at a variable rate equal to the London InterBank Offered Rate (“LIBOR”) in effect at time of borrowing. Additionally, under the terms and conditions of the loan agreement, there is no annual fee and any amount outstanding under the loan facility may be paid at any time in whole or in part without penalty.

As of December 31, 2013, the Company had no borrowings outstanding under the facility and approximately $4,500,000 of borrowing availability. The Company has no current plans to borrow from this credit facility as it believes cash generated from operations will adequately meet near-term working capital requirements.
