ITEM 1. BUSINESS

Our Company

Mercury Systems, Inc. is a leading high-tech commercial provider of more affordable secure and sensor processing subsystems designed and made in the U.S.A. powering today's critical defense and intelligence applications. We deliver innovative solutions, rapid time-to-value and service and support to our defense prime contractor customers. Our products and solutions have been deployed in more than 300 programs with over 25 different defense prime contractors. Key programs include Aegis, Patriot, Surface Electronic Warfare Improvement Program ("SEWIP"), Gorgon Stare, Predator, F-35 and Reaper. Our organizational structure allows us to deliver capabilities that combine technology building blocks and deep domain expertise in the defense sector. We operate across a broad spectrum of defense programs and deliver our solutions and services via two operating segments: (i) Mercury Commercial Electronics; and (ii) Mercury Defense Systems.

Mercury Commercial Electronics, or MCE, provides more affordable, innovative, commercially designed and developed, specialized processing subsystems for critical defense and intelligence applications. We deliver innovative solutions, rapid time-to-value and service and support to our prime defense contractors customers. Our technologies and capabilities include embedded processing modules and subsystems, RF and microwave multi-function assemblies as well as subsystems, and RF and microwave components.

MCE utilizes leading edge, high performance computing technologies architected by leveraging open standards and open architectures to address highly data-intensive applications that include data signal, sensor and image processing; all of this while addressing the packaging challenges, often referred to as “SWaP” (size, weight, and power) that are common in military applications. In addition, MCE designs and builds RF and microwave components and subsystems to meet the needs of the electronic warfare ("EW"), signals intelligence ("SIGINT") and other high bandwidth communications requirements and applications.

Mercury Defense Systems, or MDS, provides significant capabilities relating to pre-integrated, open, more affordable EW, electronic attack ("EA") and electronic counter measure ("ECM") subsystems, SIGINT and electro-optical/infrared ("EO/IR") processing technologies, and radar environment test and simulation systems. MDS deploys these solutions on behalf of defense prime contractors and the Department of Defense ("DoD"), leveraging commercially available technologies and solutions (or “building blocks”) from our MCE business and other commercial suppliers. MDS leverages this technology to design and build integrated sensor processing subsystems, often including classified application-specific software and intellectual property ("IP") for the C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ECM markets. MDS brings significant domain expertise to customers, drawing on over 25 years of experience in EW, SIGINT, and radar environment test and simulation.

Our two operating segments allow us to deliver capabilities that combine technology building blocks, deep domain expertise in the defense sector and critical solution areas, and specialized skills in serving the DoD and the intelligence community.

Our consolidated revenues, income from continuing operations and adjusted EBITDA for fiscal 2015 were $234.8 million, $14.4 million and $44.4 million, respectively. Our consolidated revenues, (loss) from continuing operations and adjusted EBITDA for fiscal 2014 were $208.7 million, $(4.1) million and $23.5 million, respectively. See the Non-GAAP Financial Measures section of this annual report for a reconciliation of our adjusted EBITDA to net income (loss) from continuing operations.

Recent Developments

During fiscal 2015, we successfully completed the final phase of integration activities relating to our previous acquisitions. The acquisition integration plan included the consolidation of manufacturing facilities, centralization of administrative and manufacturing functions using common information systems and processes, and realignment of research and development resources. Restructuring expenses in fiscal 2015 amounted to $3.2 million and affected both the MCE and MDS reportable segments. We currently do not anticipate any future restructuring activities.

3

During fiscal 2015, we also completed the sale of our former operating segment Mercury Intelligence Systems ("MIS"). Since the fourth quarter of fiscal 2014, MIS has been reported as a discontinued operation for all periods presented.

Our History

Since 1981, we have operated as a provider of advanced embedded computing products primarily for end markets in the defense industry. Over time, we expanded our business to focus on a number of commercial end markets, including the biotechnology, embedded systems and professional services, visual imaging software and life sciences markets. While this strategy was designed to expand our target market, in the mid-2000’s many of these new businesses required large investments, which significantly reduced our profitability, and we found ourselves spread across several disparate, unprofitable end-user segments.

In November 2007, we embarked on a strategy to refocus the business and return to growth and profitability. Since then, we have successfully sold or shut down five non-core business units, returned the Company to profitability and growth for the next four consecutive years, and transformed the Company into a provider of commercially developed, specialized processing subsystems, and services for critical commercial, defense and intelligence applications. Fiscal 2013 was a challenging year in light of uncertainty within the defense sector while fiscal 2014 was a return to revenue growth and improved operating performance positioning us such that we achieved our target business model in fiscal 2015. Fiscal 2015 highlights include:

• bookings of $268.6 million with a 1.14 book-to-bill ratio;

• backlog of $208.0 million;

• revenue growth of 12.5%;

• earnings from continuing operations of $0.44 per diluted share;

• cash provided by operating activities of $32.2 million;

• near doubling of adjusted EBITDA to $44.4 million; and

• completion of our acquisition integration activities.

Over the past eight years, we continued to have success on programs such as Aegis, Global Hawk, Gorgon Stare, Predator, F-35 and Reaper and have reinvested in our business. We improved our position in our target markets, with major design wins including the Patriot missile program, and SEWIP, the EW improvement program for surface vessels to counteract a variety of emerging threats. In fiscal 2010, we grew organically, improved our working capital position and profitability metrics, continued to refresh our product portfolio, and grew our services and systems integration business. We strengthened our position in our core intelligence, surveillance and reconnaissance ("ISR"), EW and ballistic missile defense markets. In fiscal 2011 and 2012, we continued to strengthen and grow our core business by enhancing our product portfolio and increasing our ISR, EW, and missile defense system domain expertise and capabilities. During fiscal 2013, we addressed significant industry headwinds aggressively by aligning our cost structure to lower revenue levels via two restructuring actions. These initiatives reduced our operating expenses by approximately $22 million annually. In addition, we acquired unique EW program capabilities through the acquisition of Micronetics early in fiscal 2013. During fiscal 2014, we completed the bulk of the integration of our recent acquisitions, including consolidating four facilities, moving into a new Advanced Microelectronics Center, and installing integrated business systems. In fiscal 2015, we completed the final phase of acquisition integration activities relating to our previous acquisitions and created a business and operations platform that we can continue to grow organically and scale through future acquisitions. The completed acquisition integration plan is expected to reduce our operating expenses by approximately $16 million annually. Our continued momentum in revenue growth, coupled with the operating leverage yielded by our now-completed integration plan, has begun translating into increased shareholder value.

We continue to be successful on our existing programs and to pursue new design wins on high growth, high priority programs. In response to new and emerging threats, and the need for better intelligence in shorter time frames, we have developed new products and capabilities that, in conjunction with our customers, seek to address those areas of concern. We have also grown and anticipate growing further through acquisitions that will complement, strengthen and grow our core business. While we look at acquisitions on an on-going basis, we also are doing this as we balance our assessment of the industry environment, our business outlook and the potential to further build-out the sensor processing chain, all while also prudently managing the business. As a result of these efforts, we believe we are well-positioned to capture existing and future growth opportunities in our end markets. We also continually look at our organizational, product development, and go-to-market capabilities to ensure we maintain an orientation towards “time to value” for our customers. This approach will help us reach our goal of providing the best solutions as we apply our commercially developed technologies to solve complex customer problems.

Our Market Opportunity

Our market opportunity is defined by the growing demand for domestically designed and manufactured advanced sensor and mission processing capabilities for critical defense and intelligence applications. Our primary market has historically been the defense sector, specifically C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ballistic missile defense; and commercial markets, which include commercial communications and other commercial computing applications. We believe we are well-positioned in growing, sustainable market segments of the defense sector that leverage advanced technology to improve warfighter capability and provide enhanced force protection capabilities.

We believe there are a number of evolving trends that are reshaping our target market and accordingly provide us with attractive growth opportunities, including:

The defense electronics market is expected to grow in government fiscal 2016, in spite of DoD budget uncertainty, opaque execution of the U.S. budget sequestration mandate, and on-going uncertainty around future spending. According to The Teal Group, world defense electronics funding available to the U.S. was approximately $42.8 billion in fiscal 2015, or approximately 8.7% of the government fiscal 2015 appropriated U.S. DoD base budget. The defense electronics market is projected to increase to $43.0 billion in government fiscal 2016. We believe ISR, EW and ballistic missile defense have a high priority for future DoD spending. We have positioned ourselves well in these important areas and have won a position on many programs and platforms. We continue to build on our strengths in the design and development of performance optimized electronic subsystems for the ISR and EW markets. As a leader in these markets, we often contract with multiple defense prime contractors as they bid for a particular project, thereby increasing our chance of a successful outcome.

The rapidly expanding demand for tactical ISR is leading to significant growth in sensor data being generated, causing even greater demand for the capability of our products to process data onboard platforms. An increase in the prevalence and resolution of ISR sensors is generating significant growth in the associated data that needs to be turned into information for the warfighter in a timely manner. In addition, several factors are driving the defense and intelligence industries to demand greater capability to collect and process data onboard the aircraft, unmanned aerial vehicles, or UAVs, ships and other vehicles, which we refer to collectively as platforms. Each platform has limited communications bandwidth and cannot realistically transmit all the data that is collected onboard the platform, and this problem will increase over time as sensor generated data will continue to outstrip data communication capabilities. Looking forward, we believe our armed forces will need platforms that operate more autonomously and possibly in denied communication environments. In addition, the platforms themselves require increased persistence, and reducing the need to communicate data off the platform can help increase the ability of the platform to remain on or fly above the battlefield for extended periods. Finally, the scarcity and cost of human analysts, the demand for timely and relevant quality information and the increasing need to fuse data not only from multiple onboard sensors but also with intelligence generated from other platforms is causing even greater demand for the onboard processing capabilities our products provide.

Rogue nations’ missile programs and threats from peer nations are causing greater investment in advanced new radar, EW and ballistic missile defense capabilities. There are a number of new and emerging threats, such as peer nations developing stealth technologies, including stealth aircraft and new anti-ship ballistic missiles that potentially threaten the U.S. naval fleet. Finally, U.S. armed forces require enhanced signals intelligence and jamming capabilities. In response to these emerging threats, we have engaged in the following:

• we provide the core radar processing on both the Aegis ballistic missile defense system as well as the Patriot missile system, a ground-based missile defense platform;

• we provide advanced RF, microwave and digital products for the U.S. Navy's SEWIP Block 2 program, designed to upgrade the Naval Surface Fleet EW capability and counteract a range of new emerging threats;

• we provide radar processing capabilities for the F-22 Raptor and F-35 Joint Strike Fighter, the latest generation of U.S. stealth-enabled fighters;

• we provide RF and microwave content for the U.S. Airforce F-15 EW upgrade program, designed to provide fighter jets with advanced radar warning and countermeasures capabilities. This is applicable to both U.S. DoD and foreign military sales; and

• to respond to the need for the modernization and upgrades to radar capabilities on the F-16, we achieved a new design win for the next generation of the Scalable Agile Beam Radar, or SABR, program.

The long-term DoD budget pressure is pushing more dollars toward upgrades of the electronic subsystems on existing platforms, which may increase demand for our products. The DoD is moving from major new weapons systems developments to upgrades of the electronic subsystems on existing platforms. These upgrades are expected to include more sensors, signal processing, ISR algorithms, multi-intelligence fusion exploitation, computing and communications. We believe that upgrades to provide new urgent war fighting capability, driven by combatant commanders, are occurring more rapidly than traditional defense prime

5

contractors can easily react to. We believe these trends will cause defense prime contractors to increasingly seek out our high performance, cost-effective open architecture products.

Defense procurement reform is causing the defense prime contractors to outsource more work to commercial companies. The U.S. government is intensely focused on making systems more affordable and shortening their development time. As a company that provides commercial items to the defense industry, we believe our products are often more affordable than products with the same functionality developed by a defense prime contractor. Defense prime contractors are increasingly being asked to work under firm fixed price contract awards, which can pressure profit margins and increase program risk. Defense prime contractors are also being asked to produce systems much more rapidly than they have in the past. In addition, the U.S. government is demanding more use of commercial items and open system architectures. In this budget environment, there are fewer research and development dollars available with which defense prime contractors can invest early-on to differentiate their offerings while competing for new program awards or re-competes. As a result, defense prime contractors are generally trying to adjust their cost model from a high fixed cost model to a variable cost model. All of these factors are providing incentives for defense prime contractors to outsource more work to subcontractors with significant expertise and cost-effective technology capabilities, and we have transformed our business model over the last several years to address these long-term outsourcing needs and other trends.

Our Business Strategy

Our strategy is built around our key strengths as a leading high-tech commercial provider of more affordable secure and sensor processing subsystems designed and made in the U.S.A. powering today's critical defense and intelligence applications. By driving this strategy consistently, we are able to help our customers, mostly defense prime contractors, to reduce program cost, minimize technical risk, and stay on-schedule. Tactically, we have a reputation of relentless execution on behalf of our customers that supports the successful evolution of our strategy.

We intend to accelerate our strategic direction through continued investment in advanced new products and solutions development in the fields of radio frequency, analog-to-digital and digital to analog conversion, advanced multi- and many-core sensor processing systems including GPUs, embedded security, digital storage, and digital radio frequency memory ("DRFM") solutions as well as software defined communications capabilities. We leverage our engineering development services including systems integration to accelerate our move to become a commercial outsourcing partner to the large defense prime contractors as they seek the more rapid design, development and delivery of affordable, commercially developed, open sensor processing solutions within the markets we serve. Our services-led engagements can help lead to long-term production subsystem annuity revenues that will continue long after the initial services are delivered. This business model positions us to be paid for work we would have previously expensed through our own income statement, to team concurrently with multiple defense prime contractors as they pursue new business with the government, and to engage with our customers much earlier in the design cycle and ahead of our competition. In fiscal 2013, 2014, and 2015, we have substantially added to our technology portfolio by adding capabilities in RF and microwave subsystems and components as critical building blocks to support programs in EW, EA, and ECM.

Key elements of our strategy to accomplish our continued growth objectives include:

Achieve Design Wins on High Growth, High Priority Defense Programs. We believe our advanced embedded sensor processing solutions position us well going forward to capture design wins on key high growth, high priority defense programs within our targeted segments of the C4ISR market. We have won designs in persistent ISR related signals intelligence payloads on UAVs and other aerial platforms. As a result of these successes, we now have significant content on major UAV platforms, including Global Hawk, Predator, Triton, Reaper and Gorgon Stare. Our ballistic missile defense wins include additional designs on the Aegis program, as well as wins on the Patriot missile program. In EW, we have won key designs related to the U.S. Navy's SEWIP program and the Ships Signal Exploitation Equipment ("SSEE") programs. Additional wins in the critical EW space include the Navy's Filthy Badger and Filthy Buzzard programs, focusing on vulnerability assessment and training for manned aircraft. Together, these wins represent substantial opportunity for us in the years ahead.

Continue to Provide Excellent Performance on Our Existing Programs. The foundation for our growth remains our continued involvement with existing programs that are in late-stage development or currently in production, such as Aegis, the F-35 Joint Strike Fighter, Patriot missile, the F-16 and F-15 aircrafts, the Global Hawk, Predator and Reaper UAVs, the P-8 MMA as well as the Suite of Integrated Radio Frequency Countermeasures ("SIRFIC") program. As part of a long-term reprioritization, the DoD is shifting its emphasis from major new weapons systems development to upgrades of existing programs and platforms. We believe the upgrades on these programs focus on four key areas: improved sensors; more advanced on-board embedded computing; enhanced ISR algorithms; and better communications on and off the platform. A key element of our strategy is to continue to provide high performance, cost-effective solutions on these programs and for these customers.

Pursue Strategic, Capability-Enhancing Acquisitions. We will continue to pursue strategic acquisitions to augment our businesses using the following strategies: adding technologies or products that expand MCE's core business by competing more

6

effectively in the ISR, EW, and missile defense markets; adding content and services to the defense programs and platforms in which we currently participate or could participate in the future and enhancing key customer relationships and forming relationships with potential new customers. Our acquisitions of LNX and KOR in fiscal 2011 and 2012 supported these objectives. Adding LNX to our business significantly strengthened our product portfolio in radio frequency and our capabilities in signals intelligence and EW. Similarly, adding KOR has brought key domain expertise in EW and capabilities with DRFM technologies that combine well with the RF domain expertise of LNX and the embedded computing and packaging design expertise developed organically at Mercury. Our acquisition of Micronetics in fiscal 2013 expanded our RF and microwave technology and subsystems integration capabilities. Our acquisition strategy also focuses on scaling our operations and broadening our program and customer base.

Capitalize on Outsourcing and Other Dynamics in the Defense Industry. We are well-positioned to take advantage of several changing dynamics in the defense industry. Defense prime contractors are increasingly being awarded firm fixed price contracts. These contracts shift risk to the defense prime contractors, and as a result they are beginning to outsource increasing levels of subsystem development and production and other higher value program content. In addition, the U.S. government is shifting toward shorter program timelines, which require increased flexibility and responsiveness from defense prime contractors. Finally, more programs are moving to open systems architectures encompassing best-of-breed capabilities. We believe that these dynamics will result in defense prime contractors outsourcing increasing levels of program content to us as a provider of differentiated products, subsystems engineering services and system integration.

Leverage Our Research and Development Efforts to Anticipate Market Needs and Maintain our Technology Leadership. Our high performance, quick reaction subsystems and capabilities require increasingly more sophisticated hardware, software and middleware technology. In addition, as the defense industries shift to products with open systems architectures, we believe that our software expertise will become increasingly important and differentiates us from many of our competitors as we have the ability to map complex algorithms onto size, weight, and power-constrained on-board embedded sensor processing solutions. We have substantially and will continue to refresh both our sensor processing and multicomputer product lines while increasing our product development velocity. Faster product development velocity aligns us with the U.S. government’s demands on the defense prime contractors for quick reaction capabilities. By shortening our product development times, we have been able to quickly launch the products we need to win new designs from the defense prime contractor community that will ultimately generate bookings and revenue for us. We intend to continue to utilize company and customer-funded research and development, as well as our acquisition strategy, to develop technologies, products and solutions that have significant potential for near-term and long-term value creation in the defense industry. We devote significant resources in order to anticipate the future requirements in our target defense markets, including monitoring and pioneering advances in advanced embedded computing hardware and software, anticipating changes in U.S. government spending and procurement practices and leveraging insight from direct interaction with our customers.

Our Competitive Strengths

We believe the following competitive strengths will allow us to take advantage of the evolving trends in our industry and successfully pursue our business strategy:

Subsystem Solutions Provider for the C4ISR and EW Markets. Through our commercially developed, specialized processing subsystem solutions, we address the challenges associated with the collection and processing of massive, continuous streams of data and dramatically shorten the time that it takes to give information to U.S. armed forces at the tactical edge. Our solutions are specifically designed for flexibility and interoperability, allowing our products to be easily integrated into larger system-level solutions. Our ability to integrate subsystem-level capabilities allows us to provide solutions that most effectively address the mission-critical challenges within the C4ISR market, including multi-intelligence data fusion and intelligence processing onboard the platform. We leverage our deep expertise in embedded multi-computing, embedded sensor processing, with the recent addition of our RF and microwave subsystems and components, along with strategic investments in research and development to provide solutions across the sensor processing chain. Our deep domain knowledge within MDS rounds-out our full capabilities in service to our prime contractor and DoD customers.

Diverse Mix of Stable, Growth Programs Aligned with DoD Funding Priorities. Our products and solutions have been deployed on more than 300 different programs and over 25 different defense prime contractors. We serve high priority markets for the DoD and foreign militaries, such as UAVs, ballistic missile defense, airborne reconnaissance, EW, ECM, and have secured positions on mission-critical programs including Aegis, Predator and Reaper UAVs, F-35 Joint Strike Fighter, Patriot missile, and SEWIP. In addition, we consistently leverage our technology and capability across 15 to 20 programs on an annual basis, providing significant operating leverage and cost savings.

Value-Added Subsystem Solution Provider for Defense Prime Contractors. Because of the DoD’s shift towards a firm fixed price contract procurement model, an increasingly uncertain budgetary and procurement environment, and increased budget pressures from both the U.S. and allied governments, defense prime contractors are accelerating their move towards outsourcing opportunities to help mitigate the increased program and financial risk. Our differentiated advanced sensor processing solutions

7

offer meaningful capabilities upgrades for our customers and enable the rapid, cost-effective deployment of systems to the end customer. We believe our open architecture subsystems offer differentiated sensor processing and data analytics capabilities that cannot be easily replicated. Our solutions minimize program risk, maximize application portability, and accelerate customers’ time to market.

MDS Enables the Delivery of Platform-Ready Solutions for Classified Programs. MDS was created in fiscal 2013 to enable us to directly pursue systems integration opportunities within the DoD. On top of that, we have the ability, within MDS, to draw on the critical subsystem innovations from MCE. We believe the development work through MDS will provide us leverage and implement key classified government intellectual property, including critical intelligence and signal processing algorithms. Within MDS, we will also be able to leverage our combination of domain knowledge, plus building blocks from MCE to serve the needs of our core defense prime contractor customer base. We believe that MDS also provides us the opportunity to directly integrate these building blocks along with intellectual property onto our existing MCE business, enabling us to deliver affordable, platform-ready integrated ISR subsystems that leverage our open architecture solutions and address key government technology and procurement concerns. MDS operations in this environment will also influence future product development so that critical future needs can be met in a timely manner.

Advanced Microelectronics Centers. Our Advanced Microelectronics Centers (“AMCs”) in Hudson, New Hampshire and West Caldwell, New Jersey design, build and test both RF and microwave components and subsystems in support of a variety of key customer programs. With our fiscal 2014 move into our new AMC in Hudson, New Hampshire, including the installation of integrated business systems into both our AMCs, we have a platform for scalable, continued growth in our RF and microwave product lines. With our company-wide focus on continuous improvement in our security policies and practices, our AMCs, like most of our facilities, have earned Superior security ratings in vulnerability assessments conducted by the Defense Security Service ("DSS"). A Superior rating, the highest level awarded to cleared defense contractors by DSS, is awarded to contractors that consistently and fully implement the requirements of the National Industrial Security Program Operating Manual in an effective fashion, resulting in a security posture that is superior to other contractors of similar size and complexity. Our scalable microelectronics manufacturing operations at our AMCs enable rapid, cost-effective deployment of RF and microwave solutions to our customers.

Long-Standing Industry Relationships. We have established long-standing relationships with defense prime contractors, the U.S. government and other key organizations in the defense industry over our 30 years in the defense electronics industry. Our customers include BAE Systems, the Boeing Company, Exelis, Lockheed Martin Corporation, Northrop Grumman Corporation, and Raytheon Company. Over this period, we have become recognized for our ability to develop new technologies and meet stringent program requirements. We believe we are well-positioned to maintain these high-level customer engagements.

Proven Management Team. Over the past several years, our senior management team has refocused the Company on its economic core, developed a long-term compelling strategy for the defense markets and restored profitability to the business. Having completed these critical steps to rebuild the Company and with a senior management team with significant experience in growing and scaling businesses, both through operating execution and acquisitions, we believe that we have demonstrated our operational capabilities and we are well-positioned for the next phase to transform, grow and scale our business.

Our Solutions and Products

Services

As part of our strategy, we are focusing on being a commercial outsourcing partner to the large defense prime contractors as they seek the more rapid design, development and delivery of affordable, commercially developed, specialized processing solutions within the markets we serve. We deliver subsystem level engineering expertise as well as ongoing systems integration services addressing our strategy to capitalize on the multi-billion dollar subsystem market within the defense embedded electronics market segment.

As the U.S. government mandates more outsourcing and open standards, a major shift is occurring within the defense prime contractor community towards procurement of integrated subsystems that enable quick application level porting through standards-based methodologies. We believe that our core expertise in this area is well aligned to capitalize on this trend. By leveraging our open architecture and high performance modular product set, we provide defense prime contractors with rapid deployment and quick reaction capabilities through our professional services and systems integration offerings. This results in less risk for the defense prime contractors, shortened development cycles, quicker solution deployment and reduced lifecycle costs.

We define service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold by us. Examples of our service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. We combine our product and

8

service revenues into a single class as services revenues do not exceed 10 percent of total revenues. Formerly, a significant portion of our service revenues were provided by our former MIS operating segment, which was disposed of in fiscal 2015 and classified as a discontinued operation in all periods presented herein.

Software Products

We actively design, market and sell complete software and middleware environments to accelerate development and execution of complex signal and image processing applications on a broad range of heterogeneous, multi-computing platforms. Our software suite is based on open standards and includes heterogeneous processor support with extensive high performance math libraries, multi-computing fabric support, net-centric and system management enabling services, extended operating system services, board support packages and development tools.

Our software is developed using some of the most advanced integrated development environments ("IDE’s"), such as Eclipse, and our work is done on multiple platforms including open source platforms such as Linux. Our software development teams are schooled in the most up-to-date software development methodologies.

Our software and middleware provides customer application-level algorithm portability across rapidly evolving hardware processor types with math and input/output, or I/O, interfaces running at industry leading performance rates. In order to develop, test and integrate software ahead of hardware availability, we have invested in the notion of a Virtual Multi-Computer. The Virtual Multi-Computer model allows for concurrent engineering internally and with customers to accelerate time to deployment, improve quality and reduce development costs. In most cases, these software products are bundled together with broader solutions including hardware and/or services, while in other cases they are licensed separately.

Our multi-computer software packages are marketed and licensed under the MultiCore Plus^® registered trademark. These software products are a key differentiator for our systems business and represent only a modest amount of stand-alone revenue. We generally charge a user-based development license fee and bundle software run-time licenses with our hardware. We offer a standards-based software value proposition to our customers and provide this offer through several integrated software packages and service offerings.

Hardware Products

We offer a broad family of products designed to meet the full range of requirements in compute-intensive, signal processing and image processing applications, multi-computer interconnect fabrics, sensor interfaces and command and control functions. To maintain a competitive advantage, we seek to leverage technology investments across multiple product lines. We are also influential in the industry-standard organizations associated with our market segments. For example, we started the OpenVPX^TM initiative with the goal of providing customers with multi-vendor interoperable hardware built to well-defined system standards. We continue to leverage our embedded high performance processing technologies with our Intel server-class processing products as well as graphics based processor ("GPGPU") products. While this multi-computing and embedded processing technology is a core skill of Mercury Systems, the size, weight, and power ("SWaP") constraints that occur concurrent with the high performance embedded processing create unique challenges. For example, with the heat build-up involved in small subsystems, we introduced a key innovation in fiscal 2013 designed to address this challenge. The technology is called Air-Flow-By^TM and it allows previously unattainable levels of processing power within a small footprint by effectively removing heat so the server-class processors can perform at maximum designed power limits. In rugged environments where air is limited, such as high altitude operations, a technology developed in fiscal 2014 called Liquid-Flow-By^TM has been successfully customer tested allowing maximum server-class processor performance in high altitude missions. These innovative cooling techniques for the first time allow full performance server-class processing in rugged environments enabling new and advanced modes of operation that enhance the multi-intelligence, situational awareness and EW capabilities in military platforms.

Our hardware products are typically compute-intensive and require extremely high inter-processor bandwidth and high I/O capacity. These systems often must also meet significant size, weight and power constraints for use in aircraft, UAVs, ships and other vehicles, and be ruggedized for use in highly demanding use environments. They are used in both commercial industrial applications, such as ground radar air traffic control, and advanced defense and intelligence applications, including space-time adaptive processing, synthetic aperture radar, airborne early warning, command, control, communication and information systems, mission planning, image intelligence and signal intelligence systems. Our products transform the massive streams of digital data created in these applications into usable information in real time. The systems can scale from a few processors to thousands of processors.

We group our hardware products into the following categories:

• signal and image processing, multi-computer and sensor interfaces, including embedded processing boards, switch fabric boards, high speed input/output boards, digital receiver boards, and chassis-based systems using air, conduction, and proprietary cooling technologies;

• RF and microwave assemblies, including tuners, converters, transceivers, and switch filters; and

• RF and microwave components, including power amplifiers and limiters, switches, oscillators, and equalizers.

To address the current challenges facing the war fighter, our government and defense prime contractors, we have developed a new product architecture that supports a more dynamic, iterative, spiral development process by leveraging open architecture standards and leading-edge commercial technologies and products. Configured and productized as integrated subsystems, customers can rapidly and cost-effectively port and adapt their applications to changing threats.

Our open architecture is carried throughout our entire Ensemble^® product line from the very small form-factor subsystems to the high-end, where ultimate processing power and reliability is of paramount importance to the mission. Our commercially-developed hardware and software product capabilities cover the entire ISR spectrum from acquisition and digitization of the signal, to processing of the signal, through the exploitation and dissemination of the information. We work continuously to improve our hardware technology with an eye toward optimization of SWaP demands, as outlined above.

Research and Product Development

Our research and development efforts are focused on developing new products and systems as well as enhancing existing hardware and software products in mission, signal and image processing. Our research and development goal is to fully exploit and maintain our technological lead in the high-performance, real-time sensor processing industry. Expenditures for research and development amounted to $32.6 million in fiscal 2015, $35.7 million in fiscal 2014 and $32.6 million in fiscal 2013. As of June 30, 2015, we had 207 employees, including hardware and software architects and design engineers, primarily engaged in engineering and research and product development activities. These individuals, in conjunction with our sales team, also devote a portion of their time to assisting customers in utilizing our products, developing new uses for these products and anticipating customer requirements for new products.

Manufacturing

Mercury Commercial Electronics

The majority of our sales are produced in International Organization for Standardization, or ISO, 9001:2000 quality system certified facilities. The current scope of delivered hardware products includes commercial and industrial class printed circuit board assemblies (modules), complex chassis systems, and RF & microwave components and subsystems.

Our printed circuit board assemblies and chassis systems' manufacturing operations consist primarily of materials planning and procurement, final assembly and test and logistics (inventory and traffic management). We subcontract the assembly and testing of most embedded multi-computing products to contract manufacturers in the U.S. to build to our specifications. We currently rely primarily on one contract manufacturer. We have a comprehensive quality and process control plan for each of our products, which include an effective supply chain management program and the use of automated inspection and test equipment to assure the quality and reliability of our products. We perform most post sales service obligations (both warranty and other lifecycle support) in-house through a dedicated service and repair operation. We periodically review our contract manufacturing capabilities to ensure we are optimized for the right mix of quality, affordability, performance and on-time delivery.

We built out a new microelectronics facility in Hudson, New Hampshire that opened during fiscal 2014. This new facility consolidated the former microelectronics operations in Salem, New Hampshire and Hudson, New Hampshire as well as the former facilities in Ewing, New Jersey and Monroe, Connecticut. This new facility is specifically aimed at providing scalable manufacturing within our critical RF and microwave businesses. We leverage best practices in design, development, manufacturing and materials handling at this facility. The facility is part of our Advanced Microelectronics Centers, which includes our RF/microwave subsystems group in West Caldwell, New Jersey. The Advanced Microelectronics Centers design, build and test both RF and microwave components and subsystems in support of a variety of key customer programs.

Although we generally use standard parts and components for our products, certain components, including custom designed ASICs, static random access memory, FPGAs, microprocessors and other third-party chassis peripherals (single board computers, power supplies, blowers, etc.), are currently available only from a single source or from limited sources. With the exception of certain components that have gone “end of life”, we strive to maintain minimal supply commitments from our vendors and generally purchase components on a purchase order basis as opposed to entering into long-term procurement agreements with vendors. We have generally been able to obtain adequate supplies of components in a timely manner from current vendors or, when necessary

10

to meet production needs, from alternate vendors. We believe that, in most cases, alternate vendors can be identified if current vendors are unable to fulfill needs.

Mercury Defense Systems

MDS designs, develops, and manufactures digital radio frequency memory (“DRFM”) units for a variety of modern EW applications, as well as radar environment simulation and test systems for defense and intelligence applications. MDS develops high performance SIGINT payloads and electro-optical/infrared ("EO/IR") technologies for small UAV platforms as well as powerful onboard UAV processor systems for real-time Wide Area Motion Imagery ("WAMI").

Competition

Mercury Commercial Electronics

MCE operates in a highly competitive marketplace characterized by rapidly changing technology, frequent product performance improvements, increasing speed of deployment to align with warfighters’ needs, and evolving industry standards and requirements coming from our customers or the DoD. Competition typically occurs at the design stage of a prospective customer’s product, where the customer evaluates alternative technologies and design approaches.

The principal competitive factors in our market are price/performance value proposition, available new products at the time of design win engagement, services and systems integration capability, effective marketing and sales efforts, and reputation in the market. Our competitive strengths include innovative engineering in both hardware and software products, subsystem design expertise, advanced packaging capability to deliver the most optimized size, weight and power solution possible, our ability to rapidly respond to varied customer requirements, and a track record of successfully supporting many high profile programs in both the commercial and defense markets. There are a limited number of competitors across the market segments and application types in which we compete. Some of these competitors are larger and have greater resources than us. Some of these competitors compete against us at purely a board-level, others at a subsystem level. We also compete with in-house design teams at our customers. The DoD as well as the defense prime contractors are pushing for more outsourcing of subsystem designs to mitigate risk and to enable concurrent design of the platform which ultimately leads to faster time to deployment. We have aligned our strategy to capitalize on that trend and are leveraging our long standing subsystem expertise to provide this value to our customers.

Mercury Defense Systems

MDS competes with many specialized providers of EW-related solutions, test and simulation and SIGINT capabilities. These competitors range from small specialized pure play providers with limited solutions capabilities to full scale integrated providers who can provide large scale solutions and subsystems.

We work directly with the DoD as well as with defense prime contractors. We can help drive subsystem development and deployment in both a classified and unclassified environment. We can produce DRFM based ECM solutions for tactical, testing and training applications. We have developed, within MDS, high performance SIGINT payloads for small UAV platforms as well as powerful onboard UAV processor systems for real-time Wide Area Motion Imagery ("WAMI"). These systems digest multiple simultaneous image sources to produce imagery for storage and exploitation. MDS has the ability to drive engineering experience, understanding of customer needs in critical domains, and then leverage MCE's building blocks, SWaP and packaging expertise and embedded processing legacy of excellence.

Intellectual Property and Proprietary Rights

As of June 30, 2015, we held 39 patents of varying duration issued in the United States. We file U.S. patent applications and, where appropriate, foreign patent applications. We also file continuations to cover both new and improved designs and products. At present, we have several U.S. and foreign patent applications in process.

We also rely on a combination of trade secret, copyright, and trademark laws, as well as contractual agreements, to safeguard our proprietary rights in technology and products. In seeking to limit access to sensitive information to the greatest practical extent, we routinely enter into confidentiality and assignment of invention agreements with each of our employees and consultants and nondisclosure agreements with our key customers and vendors.

Backlog

As of June 30, 2015, we had a backlog of orders aggregating approximately $208.0 million, of which $166.5 million is expected to be delivered within the next twelve months. As of June 30, 2014, backlog was approximately $174.1 million. The defense backlog at June 30, 2015 was $198.9 million, a $38.1 million increase from June 30, 2014. We include in our backlog

11

customer orders for products and services for which we have accepted signed purchase orders, as long as that order is scheduled to ship or invoice in whole, or in part, within the next 24 months. Orders included in backlog may be canceled or rescheduled by customers, although the customer may incur cancellation penalties depending on the timing of the cancellation. A variety of conditions, both specific to the individual customer and generally affecting the customer’s industry, may cause customers to cancel, reduce or delay orders that were previously made or anticipated. We cannot assure the timely replacement of canceled, delayed or reduced orders. Significant or numerous cancellations, reductions or delays in orders by a customer or group of customers could materially and adversely affect our results of operations or our ability to predict future revenues. Backlog should not be relied upon as indicative of our revenues for any future period.

Employees

At June 30, 2015, we employed a total of 629 people excluding contractors, including 207 in research and development, 67 in sales and marketing, 251 in manufacturing and customer support and 104 in general and administrative functions. We have five employees located in Europe, one located in Japan, and 623 located in the United States. We do not have any employees represented by a labor organization, and we believe that our relations with our employees are good.

Customers

Our revenues are concentrated in three defense prime contractors including Lockheed Martin Corporation, Raytheon Company and Northrop Grumman Corporation for the years ended June 30, 2015, 2014 and 2013. These three defense prime contractors comprised an aggregate of 61%, 43% and 38% of our revenues in each of the years ended June 30, 2015, 2014 and 2013, respectively. While we typically have customers which compose 10% or more of our revenue, the sales to each of these customers are spread across multiple programs and platforms.

ITEM 1A. RISK FACTORS:

We depend heavily on defense electronics programs that incorporate our products and services, which may be only partially funded and are subject to potential termination and reductions and delays in government spending.

Sales of our products and related services, primarily as an indirect subcontractor or team member with defense prime contractors, and in some cases directly, to the U.S. government and its agencies, as well as foreign governments and agencies, accounted for approximately 94%, 92%, and 90% of our total net revenues in fiscal 2015, 2014, and 2013, respectively. Our products and services are incorporated into many different domestic and international defense programs. Over the lifetime of a defense program, the award of many different individual contracts and subcontracts may impact our products’ requirements. The funding of U.S. government programs is subject to Congressional appropriations. Although multiple-year contracts may be planned in connection with major procurements, Congress generally appropriates funds on a fiscal year basis even though a program may continue for many years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations and prime contracts receive such funding. The reduction or delay in funding or termination of a government program in which we are involved would result in a loss of or delay in receiving anticipated future revenues attributable to that program and contracts or orders received. The U.S. government could reduce or terminate a prime contract under which we are a subcontractor or team member irrespective of the quality of our products or services. The termination of a program or the reduction in or failure to commit additional funds to a program in which we are involved could negatively

12

impact our revenues and have a material adverse effect on our financial condition and results of operations. The U.S. defense budget frequently operates under a continuing budget resolution, which increases revenue uncertainty and volatility. During fiscal 2014, the Presidential election, bipartisan gridlock in Congress, a continuing budget resolution, and the implementation of defense budget sequestration impacted our revenues and increased uncertainty in our business and financial planning. For fiscal 2016 and beyond, the potential for further bipartisan gridlock in Congress, another continuing budget resolution, and the defense industry operating under sequestration may continue to adversely impact our revenues and increase uncertainty in our business and financial planning. In addition, delays in the funding for new or existing programs, or of the defense appropriation generally, could negatively impact our revenues and have a material adverse effect on our financial condition and results of operations for the period in which such revenues were originally anticipated. Further, oil price volatility and the decline in oil prices may negatively impact foreign military sales funding program size due to oil's impact on foreign budgets.

Economic conditions could adversely affect our business, results of operations and financial condition.

The world’s financial markets have experienced turmoil, characterized by reductions in available credit, volatility in security prices, rating downgrades of investments, and reduced valuations of securities. These events have materially and adversely impacted the availability of financing to a wide variety of businesses, including small businesses, and the resulting uncertainty has led to reductions in capital investments, overall spending levels, future product plans, and sales projections across many industries and markets. These trends could have a material adverse impact on our business. These trends could also impact our financial condition and our ability to achieve targeted results of operations due to:

• reduced and delayed demand for our products;

• increased risk of order cancellations or delays;

• downward pressure on the prices of our products;

• greater difficulty in collecting accounts receivable; and

• risks to our liquidity, including the possibility that we might not have access to our cash and short-term investments or to our line of credit when needed.

Further, the funding of the defense programs that incorporate our products and services is subject to the overall U.S. government budget and appropriation decisions and processes, which are driven by numerous factors beyond our control, including geo-political, macroeconomic, and political conditions. Increased federal budget deficits could result in reduced Congressional appropriations, such as defense budget sequestration, for the defense programs that use our defense electronics products and services. Reduced baseline defense budgets could reduce the number of funded programs in which we participate. In addition, Congress could fund U.S. government operations through a continuing budget resolution without approving a formal budget for the government fiscal year, thereby potentially reducing or delaying the demand for our products. We are unable to predict the likely duration and severity of adverse economic conditions in the United States and other countries, but the longer the duration or the greater the severity, the greater the risks we face in operating our business.

We face other risks and uncertainties associated with defense-related contracts, which may have a material adverse effect on our business.

Whether our contracts are directly with the U.S. government, a foreign government, or one of their respective agencies, or indirectly as a subcontractor or team member, our contracts and subcontracts are subject to special risks. For example:

• Changes in government administration and national and international priorities, including developments in the geo-political environment, could have a significant impact on national or international defense spending priorities and the efficient handling of routine contractual matters. These changes could have a negative impact on our business in the future.

• Our contracts with the U.S. and foreign governments and their defense prime contractors and subcontractors are subject to termination either upon default by us or at the convenience of the government or contractor if, among other reasons, the program itself has been terminated. Termination for convenience provisions generally entitle us to recover costs incurred, settlement expenses and profit on work completed prior to termination, but there can be no assurance in this regard.

• Because we contract to supply goods and services to the U.S. and foreign governments and their prime and subcontractors, we compete for contracts in a competitive bidding process and, in the event we are awarded a contract, we are subject to protests by disappointed bidders of contract awards that can result in the reopening of the bidding process and changes in governmental policies or regulations and other political factors. In addition, we may be subject to multiple rebid requirements over the life of a defense program in order to continue to participate on such program, which can result in

13

the loss of the program or significantly reduce our revenue or margin from the program. The government’s requirements for more frequent technology refreshes on defense programs may lead to increased costs and lower long term revenues.

• Consolidation among defense industry contractors has resulted in a few large contractors with increased bargaining power relative to us. The increased bargaining power of these contractors may adversely affect our ability to compete for contracts and, as a result, may adversely affect our business or results of operations in the future.

• Our customers include U.S. government contractors who must comply with and are affected by laws and regulations relating to the formation, administration, and performance of U.S. government contracts. In addition, when our business units, such as MDS, contract with the U.S. government, they must comply with these laws and regulations, including the organizational conflict-of-interest regulations. A violation of these laws and regulations could result in the imposition of fines and penalties to us or our customers or the termination of our or their contracts with the U.S. government. As a result, there could be a delay in our receipt of orders from our customers, a termination of such orders, or a termination of contracts between our business units and the U.S. government.

• We sell many products to U.S. and international defense contractors and also directly to the U.S. government as a commercial supplier such that cost data is not supplied. To the extent that there are interpretations or changes in the Federal Acquisition Regulations regarding the qualifications necessary to be a commercial item supplier, there could be a material adverse effect on our business and operating results. For example, there have been legislative proposals to narrow the definition of a “commercial item” (as defined in the Federal Acquisition Regulations) that could limit our ability to contract as a commercial item supplier. In addition, growth in our defense sales relative to our commercial sales could adversely impact our status as a commercial supplier, which could adversely affect our business and operating results. Changes in our mix of business, in federal regulations, or in the interpretation of federal regulations, may subject us to audit by the Defense Contract Audit Agency ("DCAA") for certain of our products or services. Such changes may require us to implement a DCAA cost-accounting system at our commercial item business unit. Operating under a cost-accounting business model rather than our historical commercial item business model could adversely impact our revenues and profitability.

• We qualify as a “small business” for government contracts purposes under the definition of that term in an applicable NAICS code because we have fewer than 1,000 employees. As we grow and potentially have over 1,000 employees in the future, we would no longer qualify as a small business. Loss of our small business status could negatively impact us, including our customers purchases from us would not qualify as purchases from a small business, customers may flow down additional Federal Acquisition Regulation, or FAR, clauses in their contracts with us that are less favorable than our existing contract terms and conditions, and the flow down of certain FAR clauses may require us to implement a DCAA cost-accounting system at our commercial item business unit.

• We are subject to the Defense Federal Acquisition Regulations Supplement, referred to as DFARS, in connection with our defense work for the U.S. government and defense prime contractors. Amendments to the DFARS, such as the amendment to the DFARS specialty metals clause requiring that the specialty metals in specified items be melted or produced in the U.S. or other qualifying countries, may increase our costs for certain materials or result in supply-chain difficulties or production delays due to the limited availability of compliant materials. Compliance with the new conflict minerals regulations enacted pursuant to the Dodd Frank legislation poses similar risks and increases our costs.

• The U.S. government or a defense prime contractor customer could require us to relinquish data rights to a product in connection with performing work on a defense contract, which could lead to a loss of valuable technology and intellectual property in order to participate in a government program.

• We are subject to various U.S. federal export-control statutes and regulations which affect our business with, among others, international defense customers. In certain cases the export of our products and technical data to foreign persons, and the provision of technical services to foreign persons related to such products and technical data, may require licenses from the U.S. Department of Commerce or the U.S. Department of State. The time required to obtain these licenses, and the restrictions that may be contained in these licenses, may put us at a competitive disadvantage with respect to competing with international suppliers who are not subject to U.S. federal export control statutes and regulations. In addition, violations of these statutes and regulations can result in civil and, under certain circumstances, criminal liability as well as administrative penalties which could have a material adverse effect on our business and operating results. For fiscal 2015, we needed to further adapt our export procedures for the new federal export reform regulations that went into effect during the fiscal year.

• We anticipate that sales to our U.S. prime defense contractor customers as part of foreign military sales (“FMS”) programs will be an increasing part of our business going forward.  These FMS sales combine several different types of risks and uncertainties highlighted above, including risks related to government contracts, risks related to defense contracts, timing and budgeting of foreign governments, and approval from the U.S. and foreign governments related to the programs, all

14

of which may be impacted by macroeconomic and geopolitical factors outside of our control. For example, the decline in oil prices may negatively impact foreign defense budgets.

• Certain of our employees with appropriate security clearances may require access to classified information in connection with the performance of a U.S. government contract. We must comply with security requirements pursuant to the National Industrial Security Program Operating Manual, or NISPOM, and other U.S. government security protocols when accessing sensitive information. Failure to comply with the NISPOM or other security requirements may subject us to civil or criminal penalties, loss of access to sensitive information, loss of a U.S. government contract, or potentially debarment as a government contractor.

• We may need to invest additional capital to build out higher level security infrastructure at certain of our facilities to capture new design wins on defense programs with higher level security requirements. Failure to invest in such infrastructure may limit our ability to obtain new design wins on defense programs. In addition, we may need to invest in additional secure laboratory space to efficiently integrate subsystem level solutions and maintain quality assurance on current and future programs.

The loss of one or more of our largest customers, programs, or applications could adversely affect our results of operations.

We are dependent on a small number of customers for a large portion of our revenues. A significant decrease in the sales to or loss of any of our major customers would have a material adverse effect on our business and results of operations. In fiscal 2015, Raytheon Company accounted for 37% of our total net revenues, Lockheed Martin Corporation accounted for 20% of our total net revenues, and Northrop Grumman Corporation accounted for 4% of our total net revenues. In fiscal 2014, Lockheed Martin Corporation accounted for 18% of our total net revenues, Raytheon Company accounted for 13% of our total net revenues, and Northrop Grumman Corporation accounted for 12% of our total net revenues. In fiscal 2013, Lockheed Martin Corporation accounted for 17% of our total net revenues, Raytheon Company accounted for 10% of our total net revenues, and Northrop Grumman Corporation accounted for 11% of our total net revenues. The defense market is highly acquisitive, which could lead to further concentration in our largest customers. Customers in the defense market generally purchase our products in connection with government programs that have a limited duration, leading to fluctuating sales to any particular customer in this market from year to year. In addition, our revenues are largely dependent upon the ability of customers to develop and sell products that incorporate our products. No assurance can be given that our customers will not experience financial, technical or other difficulties that could adversely affect their operations and, in turn, our results of operations. Additionally, on a limited number of programs the customer has co-manufacturing rights which could lead to a shift of production on such a program away from us which in turn could lead to lower revenues.

We are dependent on sales for radar applications for a large portion of our revenues. Sales related to radar applications accounted for 61%, 53% and 38% of our total net revenues for fiscal 2015, 2014, and 2013, respectively. While our radar sales relate to multiple different platforms and defense programs, our revenues are largely dependent upon our customers incorporating our products into radar applications. For the fiscal years ended June 30, 2015, 2014 and 2013, the Aegis program individually comprised 12%, 15% and 10% of the Company's revenues, respectively. For the fiscal years ended June 30, 2015, Patriot and F-35 accounted for 18% and 16% of the Company's revenue, respectively. Loss of a significant radar program could adversely affect our results of operations.

Going forward, we believe the SEWIP program and the Patriot missile defense program could be a large portion of our future revenues in the coming years, and the loss or cancellation of these programs could adversely affect our future results. In addition, as we shift our business mix toward more services-led engagements with legacy product revenues becoming a lesser amount of our total revenues, we could experience downward pressure on margins and reduced profitability. Further, new programs may yield lower margins than legacy programs, which could result in an overall reduction in gross margins.

If we are unable to respond adequately to our competition or to changing technology, we may lose existing customers and fail to win future business opportunities.

The markets for our products are highly competitive and are characterized by rapidly changing technology, frequent product performance improvements and evolving industry standards. Competitors may be able to offer more attractive pricing or develop products that could offer performance features that are superior to our products, resulting in reduced demand for our products. We may be unable to keep pace with competitors’ marketing and the lack of visibility in the marketplace may negatively impact design wins, bookings, and revenues. Customers may also decide to reduce costs and accept the least costly technically acceptable alternative to our products or services. In addition, customers may decide to insource products that they have traditionally outsourced to us. Due to the rapidly changing nature of technology, we may not become aware in advance of the emergence of new competitors into our markets. The emergence of new competitors into markets targeted by us could result in the loss of existing customers and may have a negative impact on our ability to win future business opportunities. In addition to adapting to rapidly changing

15

technology, we must also develop a reputation as a best-of-breed technology provider. Competitors may be perceived in the market as being providers of open-source architectures versus Mercury as a closed-architecture company. Perceptions of Mercury as a high-cost provider, or as having stale technology could cause us to lose existing customers or fail to win new business. Further, our lack of strong engagements with important government-funded laboratories (e.g. DARPA, MIT Lincoln Labs, MITRE) may inhibit our ability to become subsystem solution design partners with our defense prime customers. With the reduction in force in our engineering group during fiscal 2013 as part of our cost containment efforts, we have fewer engineering resources to deliver advanced, subsystem level products to satisfy our customers' demanding expectations.

With continued microprocessor evolution, low-end systems could become adequate to meet the requirements of an increased number of the lesser-demanding applications within our target markets. Workstation or blade center computer manufacturers and other low-end single-board computer, or new competitors, may attempt to penetrate the high-performance market for defense electronics systems, which could have a material adverse effect on our business. In addition, our customers provide products to markets that are subject to technological cycles. Any change in the demand for our products due to technological cycles in our customers’ end markets could result in a decrease in our revenues.

Competition from existing or new companies could cause us to experience downward pressure on prices, fewer customer orders, reduced margins, the inability to take advantage of new business opportunities, and the loss of market share.

We compete in highly competitive industries, and our OEM customers generally extend the competitive pressures they face throughout their respective supply chains. Additionally, our markets are facing increasing industry consolidation, resulting in larger competitors who have more market share to put more downward pressure on prices and offer a more robust portfolio of products and services. We are subject to competition based upon product design, performance, pricing, quality and services. Our product performance, engineering expertise, and product quality have been important factors in our growth. While we try to maintain competitive pricing on those products that are directly comparable to products manufactured by others, in many instances our products will conform to more exacting specifications and carry a higher price than analogous products. Many of our OEM customers and potential customers have the capacity to design and internally manufacture products that are similar to our products. We face competition from research and product development groups and the manufacturing operations of current and potential customers, who continually evaluate the benefits of internal research, product development, and manufacturing versus outsourcing. This competition could result in fewer customer orders and a loss of market share.

Our sales in the defense market could be adversely affected by the emergence of commodity-type products as acceptable substitutes for certain of our products and by uncertainty created by emerging changes in standards that may cause customers to delay purchases or seek alternative solutions.

Our products for the defense market are designed for operating under physical constraints such as limited space, weight, and electrical power. Furthermore, these products are often designed to be “rugged,” that is, to withstand enhanced environmental stress such as extended temperature range, shock, vibration, and exposure to sand or salt spray. Historically these requirements have often precluded the use of less expensive, readily available commodity-type systems typically found in more benign non-military settings. Factors that may increase the acceptability of commodity-type products in some defense platforms that we serve include improvements in the physical properties and durability of such alternative products, combined with the relaxation of physical and ruggedness requirements by the military due to either a reevaluation of those requirements or the installation of products in a more highly environmentally isolated setting. These developments could negatively impact our revenues and have a material adverse effect on our business and operating results.

If we fail to respond to commercial industry cycles in terms of our cost structure, manufacturing capacity and/or personnel need, our business could be seriously harmed.

The timing, length and severity of the up-and-down cycles in the telecommunications and other commercial industries are difficult to predict. This cyclical nature of the industries in which we operate affects our ability to accurately predict future revenue, and in some cases, future expense levels. In the current environment, our ability to accurately predict our future operating results is particularly low. During down cycles in our industry, the financial results of our customers may be negatively impacted, which could result not only in a decrease in orders but also a weakening of their financial condition that could impair our ability to recognize revenue or to collect on outstanding receivables. When cyclical fluctuations result in lower than expected revenue levels, operating results may be adversely affected and cost reduction measures may be necessary in order for us to remain competitive and financially sound. During periods of declining revenues, we must be in a position to adjust our cost and expense structure to reflect prevailing market conditions and to continue to motivate and retain our key employees. If we fail to respond, then our business could be seriously harmed. In addition, during periods of rapid growth, we must be able to increase manufacturing capacity and personnel to meet customer demand. We can provide no assurance that these objectives can be met in a timely manner in response to industry cycles. Each of these factors could adversely impact our operating results and financial condition.

Implementation of our growth strategy may not be successful, which could affect our ability to increase revenues.

Our growth strategy includes developing new products, adding new customers within our existing markets, and entering new markets, as well as identifying and integrating acquisitions and achieving revenue and cost synergies and economies of scale. Our ability to compete in new markets will depend upon a number of factors including, among others:

• our ability to create demand for products in new markets;

• our ability to manage growth effectively;

• our ability to respond to changes in our customers’ businesses by updating existing products and introducing, in a timely fashion, new products which meet the needs of our customers;

• our ability to develop a reputation as a best-of-breed technology provider;

• the quality of our new products;

• our ability to respond rapidly to technological change; and

• our ability to successfully integrate any acquisitions that we make and achieve revenue and cost synergies and economies of scale.

The failure to do any of the foregoing could have a material adverse effect on our business, financial condition and results of operations. In addition, we may face competition in these new markets from various companies that may have substantially greater research and development resources, marketing and financial resources, manufacturing capability and/or customer support organizations.

Growing our business, in particular by providing services and products such as sophisticated subsystems for major defense programs like Patriot, SEWIP and Aegis, could strain our operational capacity and working capital demands if not properly anticipated and managed. Pursuing such growth could result in our operational and infrastructure resources being spread too thin, which could negatively impact our ability to deliver quality product on schedule and on budget. Providing quality services for subsystem level products is a key driver of our growth strategy and the failure to properly scale our capabilities to support our customers at a subsystem level could result in lost opportunities and revenues.

Future acquisitions may adversely affect our financial condition.

As part of our strategy for growth, we may continue to explore acquisitions or strategic alliances, which may not be completed or may not be ultimately beneficial to us.

Acquisitions may pose risks to our operations, including:

• problems and increased costs in connection with the integration of the personnel, operations, technologies, or products of the acquired businesses;

• unanticipated costs;

• failure to achieve anticipated increases in revenues and profitability;

• diversion of management’s attention from our core business;

• adverse effects on business relationships with suppliers and customers and those of the acquired company;

• acquired assets becoming impaired as a result of technical advancements or worse-than-expected performance by the acquired company;

• failure to rationalize manufacturing capacity, locations, and operating models to achieve anticipated economies of scale, or disruptions to manufacturing and product design operations during the combination of facilities;

• volatility associated with accounting for earn-outs in a given transaction;

• entering markets in which we have no, or limited, prior experience; and

• potential loss of key employees.

In addition, in connection with any acquisitions or investments we could:

• issue stock that would dilute our existing shareholders’ ownership percentages;

• incur debt and assume liabilities;

• obtain financing on unfavorable terms, or not be able to obtain financing on any terms at all;

• incur amortization expenses related to acquired intangible assets or incur large and immediate write-offs;

17

• incur large expenditures related to office closures of the acquired companies, including costs relating to the termination of employees and facility and leasehold improvement charges resulting from our having to vacate the acquired companies’ premises; and

• reduce the cash that would otherwise be available to fund operations or for other purposes.

The failure to successfully integrate any acquisitions in an efficient or timely manner may negatively impact our financial condition and operating results, or we may not be able to fully realize anticipated savings.

We may be unable to obtain critical components from suppliers, which could disrupt or delay our ability to deliver products to our customers.

Several components used in our products are currently obtained from sole-source suppliers. We are dependent on key vendors like LSI Logic Corporation, Xilinx, Inc., and IBM Corporation for custom-designed application-specific integrated circuits (“ASICs”) and field programmable gate arrays (“FPGAs”), Freescale Semiconductor, Inc. and IBM Corporation for PowerPC microprocessors, Intel Corporation for our next generation processors, IBM Corporation for a specific SRAM, Curtiss Wright Corporation and Motorola, Inc. for chassis and chassis components and Benchmark Electronics, Inc. for board assembly, test and integration. The semiconductor industry is experiencing a significant year over year increase in demand amid an uncertain macro-economy which is limiting any investment in additional capacity. We believe this dynamic will result in increased lead-time for most classes of semiconductors and passive components and will continue to put pressure on component pricing where supply becomes constrained. Generally, suppliers may terminate their contracts with us without cause upon 30 days’ notice and may cease offering their products upon 180 days’ notice. If any of our sole-source suppliers limits or reduces the sale of these components, we may be unable to fulfill customer orders in a timely manner or at all. In addition, if these or other component suppliers, some of which are small companies, experienced financial difficulties or other problems that prevented them from supplying us with the necessary components, we could experience a loss of revenues due to our inability to fulfill orders. These sole-source and other suppliers are each subject to quality and performance issues, materials shortages, excess demand, reduction in capacity and other factors that may disrupt the flow of goods to us or to our customers, which would adversely affect our business and customer relationships. We have no guaranteed supply arrangements with our suppliers and there can be no assurance that these suppliers will continue to meet our requirements. If supply arrangements are interrupted, we may not be able to find another supplier on a timely or satisfactory basis. We may incur significant set-up costs and delays in manufacturing should it become necessary to replace any key vendors due to work stoppages, shipping delays, financial difficulties, natural or manmade disasters or other factors.

We may not be able to effectively manage our relationships with contract manufacturers.

We may not be able to effectively manage our relationship with contract manufacturers, and the contract manufacturers may not meet future requirements for timely delivery. We rely on contract manufacturers to build hardware sub-assemblies for our products in accordance with our specifications. During the normal course of business, we may provide demand forecasts to contract manufacturers up to five months prior to scheduled delivery of our products to customers. If we overestimate requirements, the contract manufacturers may assess cancellation penalties or we may be left with excess inventory, which may negatively impact our earnings. If we underestimate requirements, the contract manufacturers may have inadequate inventory, which could interrupt manufacturing of our products and result in delays in shipment to customers and revenue recognition. Contract manufacturers also build products for other companies, and they may not have sufficient quantities of inventory available or sufficient internal resources to fill our orders on a timely basis or at all.

In addition, there have been a number of major acquisitions within the contract manufacturing industry in recent periods. While there has been no significant impact on our contract manufacturers to date, future acquisitions could potentially have an adverse effect on our working relationships with contract manufacturers. Moreover, we currently rely primarily on one contract manufacturer, Benchmark Electronics, Inc. The failure of this contract manufacturer to fill our orders on a timely basis or in accordance with our customers’ specifications could result in a loss of revenues and damage to our reputation. We may not be able to replace this contract manufacturer in a timely manner or without significantly increasing our costs if such contract manufacturer were to experience financial difficulties or other problems that prevented it from fulfilling our order requirements.

With the expansion of our microwave and RF product lines in recent years, primarily related to the acquisitions of Micronetics, Inc., KOR Electronics, and LNX Corporation, the mix of products that we manufacture in-house has increased. If we are unable to develop a co-manufacturing relationship with a contract manufacturer to scale production capacity for our microwave and RF products, our ability to reduce production costs and improve product quality may be limited. With the building of our Advanced Microelectronics Center in Hudson, New Hampshire during fiscal 2014, we are becoming more vertically integrated in our microwave and RF product lines. This vertical integration could lead to higher capital intensity, labor utilization rate volatility which could affect our profitability, and higher fixed costs. Also, the changes to business processes and IT systems required to

18

combine two locations into a single site like our new Advanced Microelectronics Center may interrupt our operations for a period of time resulting in higher costs, lower revenues and missed opportunities for design wins.

We are exposed to risks associated with international operations and markets.

We market and sell products in international markets, and have established offices and subsidiaries in Europe and Japan. Revenues from international operations accounted for 2%, 4% and 6% of our total net revenues in fiscal 2015, 2014 and 2013, respectively. We also ship directly from our U.S. operations to international customers. There are inherent risks in transacting business internationally, including:

• changes in applicable laws and regulatory requirements;

• export and import restrictions;

• export controls relating to technology;

• tariffs and other trade barriers;

• less favorable intellectual property laws;

• difficulties in staffing and managing foreign operations;

• longer payment cycles;

• problems in collecting accounts receivable;

• adverse economic conditions in foreign markets;

• political instability;

• fluctuations in currency exchange rates;

• expatriation controls; and

• potential adverse tax consequences.

There can be no assurance that one or more of these factors will not have a material adverse effect on our future international activities and, consequently, on our business and results of operations.

In addition, we must comply with the Foreign Corrupt Practices Act, or the FCPA. The FCPA generally requires companies to maintain adequate record-keeping and internal accounting practices to accurately reflect the transactions of the company and prohibits U.S. companies and their intermediaries from making corrupt payments to foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment. Under the FCPA, U.S. companies may be held liable for actions taken by strategic or local partners or representatives. If we or our intermediaries fail to comply with the requirements of the FCPA, governmental authorities in the United States could seek to impose civil and criminal penalties, which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.

We may be exposed to unfavorable currency exchange rate fluctuations, which may lead to lower operating margins, or may cause us to raise prices which could result in reduced revenues.

Currency exchange rate fluctuations could have an adverse effect on our net revenues and results of operations. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in lower net revenues from such customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be adversely affected. In addition, most sales made by our foreign subsidiaries are denominated in the currency of the country in which these products are sold, and the currency they receive in payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations. We do not currently hedge our foreign currency exchange rate exposure.

If we are unable to respond to technological developments and changing customer needs on a timely and cost-effective basis, our results of operations may be adversely affected.

Our future success will depend in part on our ability to enhance current products and to develop new products on a timely and cost-effective basis in order to respond to technological developments and changing customer needs. Defense customers, in particular, demand frequent technological improvements as a means of gaining military advantage. Military planners have historically funded significantly more design projects than actual deployments of new equipment, and those systems that are deployed tend to contain the components of the subcontractors selected to participate in the design process. In order to participate in the design of new defense electronics systems, we must demonstrate the ability to deliver superior technological performance

19

on a timely and cost-effective basis. There can be no assurance that we will secure an adequate number of defense design wins in the future, that the equipment in which our products are intended to function will eventually be deployed in the field, or that our products will be included in such equipment if it eventually is deployed.

Customers in our commercial markets also seek technological improvements through product enhancements and new generations of products. OEMs historically have selected certain suppliers whose products have been included in the OEMs’ machines for a significant portion of the products’ life cycles. We may not be selected to participate in the future design of any commercial equipment, or if selected, we may not generate any revenues for such design work.

The design-in process is typically lengthy and expensive, and there can be no assurance that we will be able to continue to meet the product specifications of OEM customers in a timely and adequate manner. In addition, any failure to anticipate or respond adequately to changes in technology, customer preferences and future order demands, or any significant delay in product developments, product introductions or order volume, could negatively impact our financial condition and results of operations, including the risk of inventory obsolescence. Because of the complexity of our products, we have experienced delays from time to time in completing products on a timely basis. If we are unable to design, develop or introduce competitive new products on a timely basis, our future operating results may be adversely affected.

Our products are complex, and undetected defects may increase our costs, harm our reputation with customers or lead to costly litigation.

Our products are extremely complex and must operate successfully with complex products of other vendors. Our products may contain undetected errors when first introduced or as we introduce product upgrades. The pressures we face to be the first to market new products or functionality and the lapsed time before our products are integrated into our customer's systems increases the possibility that we will offer products in which we or our customers later discover problems. We have experienced new product and product upgrade errors in the past and expect similar problems in the future. These problems may cause us to incur significant warranty costs and costs to support our service contracts and divert the attention of personnel from our product development efforts. Undetected errors may adversely affect our product’s ease of use and may create customer satisfaction issues. If we are unable to repair these problems in a timely manner, we may experience a loss of or delay in revenue and significant damage to our reputation and business prospects. Many of our customers rely upon our products for mission-critical applications. Because of this reliance, errors, defects, or other performance problems in our products could result in significant financial and other damage to our customers. Our customers could attempt to recover those losses by pursuing products liability claims against us which, even if unsuccessful, would likely be time-consuming and costly to defend and could adversely affect our reputation.

We may be unsuccessful in protecting our intellectual property rights which could result in the loss of a competitive advantage.

Our ability to compete effectively against other companies in our industry depends, in part, on our ability to protect our current and future proprietary technology under patent, copyright, trademark, trade secret and unfair competition laws. We cannot assure that our means of protecting our proprietary rights in the United States or abroad will be adequate, or that others will not develop technologies similar or superior to our technology or design around our proprietary rights. In addition, we may incur substantial costs in attempting to protect our proprietary rights.

Also, despite the steps taken by us to protect our proprietary rights, it may be possible for unauthorized third parties to copy or reverse-engineer aspects of our products, develop similar technology independently or otherwise obtain and use information that we regard as proprietary and we may be unable to successfully identify or prosecute unauthorized uses of our technology. Furthermore, with respect to our issued patents and patent applications, we cannot assure you that any patents from any pending patent applications (or from any future patent applications) will be issued, that the scope of any patent protection will exclude competitors or provide competitive advantages to us, that any of our patents will be held valid if subsequently challenged or that others will not claim rights in or ownership of the patents (and patent applications) and other proprietary rights held by us.

If we become subject to intellectual property infringement claims, we could incur significant expenses and could be prevented from selling specific products.

We may become subject to claims that we infringe the intellectual property rights of others in the future. We cannot assure that, if made, these claims will not be successful. Any claim of infringement could cause us to incur substantial costs defending against the claim even if the claim is invalid, and could distract management from other business. Any judgment against us could require substantial payment in damages and could also include an injunction or other court order that could prevent us from offering certain products.

20

Our need for continued investment in research and development may increase expenses and reduce our profitability.

Our industry is characterized by the need for continued investment in research and development. If we fail to invest sufficiently in research and development, our products could become less attractive to potential customers and our business and financial condition could be materially and adversely affected. As a result of the need to maintain or increase spending levels in this area and the difficulty in reducing costs associated with research and development, our operating results could be materially harmed if our research and development efforts fail to result in new products or if revenues fall below expectations. In addition, as a result of our commitment to invest in research and development, spending levels of research and development expenses as a percentage of revenues may fluctuate in the future. Further, with the reduction in force in our engineering group during fiscal 2013 as part of our cost containment efforts and with reduced levels of research and development spending in fiscal 2014 and 2015 compared with prior years, we have fewer engineering resources to deliver advanced, subsystem level products to satisfy our customers' demanding expectations.

Our results of operations are subject to fluctuation from period to period and may not be an accurate indication of future performance.

We have experienced fluctuations in operating results in large part due to the sale of products and services in relatively large dollar amounts to a relatively small number of customers. Customers specify delivery date requirements that coincide with their need for our products and services. Because these customers may use our products and services in connection with a variety of defense programs or other projects with different sizes and durations, a customer’s orders for one quarter generally do not indicate a trend for future orders by that customer. As such, we have not been able in the past to consistently predict when our customers will place orders and request shipments so that we cannot always accurately plan our manufacturing, inventory, and working capital requirements. As a result, if orders and shipments differ from what we predict, we may incur additional expenses and build excess inventory, which may require additional reserves and allowances and reduce our working capital and operational flexibility. Any significant change in our customers’ purchasing patterns could have a material adverse effect on our operating results and reported earnings per share for a particular quarter. Thus, results of operations in any period should not be considered indicative of the results to be expected for any future period.

High quarterly book-ship ratios may pressure inventory and cash flow management, necessitating increased inventory balances to ensure quarterly revenue attainment. Increased inventory balances tie up additional capital, limiting our operational flexibility. Some of our customers may have become conditioned to wait until the end of a quarter to place orders in the expectation of receiving a discount. Customers conditioned to seek quarter-end discounts increase risk and uncertainty in our financial forecasting and decrease our margins and profitability.

Our quarterly results may be subject to fluctuations resulting from a number of other factors, including:

• delays in completion of internal product development projects;

• delays in shipping hardware and software;

• delays in acceptance testing by customers;

• a change in the mix of products sold to our served markets;

• production delays due to quality problems with outsourced components;

• inability to scale quick reaction capability products due to low product volume;

• shortages and costs of components;

• the timing of product line transitions;

• declines in quarterly revenues from previous generations of products following announcement of replacement products containing more advanced technology;

• potential asset impairment, including goodwill and intangibles, or restructuring charges; and

• changes in estimates of completion on fixed price service engagements.

In addition, from time to time, we have entered into contracts, referred to as development contracts, to engineer a specific solution based on modifications to standard products. Gross margins from development contract revenues are typically lower than gross margins from standard product revenues. We intend to continue to enter into development contracts and anticipate that the gross margins associated with development contract revenues will continue to be lower than gross margins from standard product sales.

21

Another factor contributing to fluctuations in our quarterly results is the fixed nature of expenditures on personnel, facilities and marketing programs. Expense levels for these programs are based, in significant part, on expectations of future revenues. If actual quarterly revenues are below management’s expectations, our results of operations will likely be adversely affected.

Further, the preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and changes in estimates in subsequent periods could cause our results of operations to fluctuate.

Changes in regulations could materially adversely affect us.

Our business, results of operations, or financial condition could be materially adversely affected if laws, regulations, or standards relating to us or our products are newly implemented or changed. In addition, our compliance with existing regulations may have a material adverse impact on us. Under applicable federal securities laws, we are required to evaluate and determine the effectiveness of our internal control structure and procedures for financial reporting. Should we or our independent registered public accounting firm determine that we have material weaknesses in our internal controls, our results of operations or financial condition may be materially adversely affected or our stock price may decline.

Changes in generally accepted accounting principles may adversely affect us.

From time to time, the Financial Accounting Standards Board, or FASB, promulgates new accounting principles that could have a material adverse impact on our results of operations or financial condition.

We rely on the significant experience and specialized expertise of our senior management and engineering staff and must retain and attract qualified engineers and other highly skilled personnel in order to grow our business successfully.

Our performance is substantially dependent on the continued services and performance of our senior management and our highly qualified team of engineers, many of whom have numerous years of experience, specialized expertise in our business, and security clearances required for certain defense projects. If we are not successful in hiring and retaining highly qualified engineers, we may not be able to extend or maintain our engineering expertise, and our future product development efforts could be adversely affected. Competition for hiring these employees is intense, especially with regard to engineers with specialized skills and security clearances required for our business, and we may be unable to hire and retain enough engineers to implement our growth strategy.

We may be unable to deliver subsystem level products and related services on time and on budget with our limited engineering resources. Without sufficient resources in hardware, software, and mechanical engineering and quality assurance we may be unable to adequately scale our business and deliver the subsystem solutions that our customers expect. We must also develop new engineering talent in our engineering base to contain high engineering costs to alleviate pressures on our margins and price points.

Increased workloads and responsibilities due to cost containment measures in recent years has led to a leaner employee base, increasing our risk of employee and organizational fatigue. Resulting lower morale and organizational disruption could lead to execution issues, missed commitments, and general employee attrition.

Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled managerial, operations, sales, marketing and customer service personnel. If we fail to attract, integrate and retain the necessary personnel, our ability to maintain and grow our business could suffer significantly. Further, stock price volatility and improvements in the economy could impact our ability to attract and retain key personnel.

If we experience a disaster or other business continuity problem, we may not be able to recover successfully, which could cause material financial loss, loss of human capital, regulatory actions, reputational harm, or legal liability.

If we experience a local or regional disaster or other business continuity problem, such as an earthquake, terrorist attack, pandemic or other natural or man-made disaster, our continued success will depend, in part, on the availability of our personnel, our office facilities, and the proper functioning of our computer, telecommunication and other related systems and operations. As we attempt to grow our operations, the potential for particular types of natural or man-made disasters, political, economic or infrastructure instabilities, or other country- or region-specific business continuity risks increases.

22

If we are unable to continue to obtain U.S. federal government authorization regarding the export of our products, or if current or future export laws limit or otherwise restrict our business, we could be prohibited from shipping our products to certain countries, which would harm our ability to generate revenue.

We must comply with U.S. laws regulating the export of our products and technology. In addition, we are required to obtain a license from the U.S. federal government to export certain of our products and technical data as well as to provide technical services to foreign persons related to such products and technical data. We cannot be sure of our ability to obtain any licenses required to export our products or to receive authorization from the U.S. federal government for international sales or domestic sales to foreign persons including transfers of technical data or the provision of technical services. Moreover, the export regimes and the governing policies applicable to our business are subject to change. We cannot assure you of the extent that such export authorizations will be available to us, if at all, in the future. If we cannot obtain required government approvals under applicable regulations in a timely manner or at all, we would be delayed or prevented from selling our products in international jurisdictions, which could adversely affect our business and financial results.

If we suffer any data breaches involving the designs, schematics or source code for our products or other sensitive information, our business and financial results could be adversely affected.

We securely store our designs, schematics and source code for our products as they are created. A breach, whether physical, electronic or otherwise, of the systems on which this sensitive data is stored could lead to damage or piracy of our products. If we are subject to data security breaches from external sources or from an insider threat, we may have a loss in sales or increased costs arising from the restoration or implementation of additional security measures, either of which could adversely affect our business and financial results. Other potential costs could include loss of brand value, incident response costs, loss of stock market value, regulatory inquiries, litigation, and management distraction. In addition, a security breach that involved classified information could subject us to civil or criminal penalties, loss of a government contract, loss of access to classified information, or debarment as a government contractor. Similarly, a breach that involved loss of customer-provided data could subject us to loss of a customer, loss of a contract, litigation costs and legal damages, and reputational harm.

The highly-publicized cyber-attack on Sony Pictures Entertainment demonstrates the vulnerability of companies to cyber-attacks and the severe impact these attacks can have. In addition to the potential costs discussed above, the Sony cyber-attack illustrates that such attacks can also damage physical infrastructure (e.g. corrupted servers) and destroy all copies of company intellectual property on a company's network.

We may need to invest in new information technology systems and infrastructure to scale our operations.

We may need to adopt new information technology systems and infrastructure to scale our business and obtain the synergies from prior and future business acquisitions. Our older information technology systems and infrastructure could create product development or production work stoppages, negatively impact product delivery times and quality, and increase our compliance costs. Failure to invest in newer information technology systems and infrastructure may lead to operational inefficiencies and increased compliance costs and risks. In addition, an inability to maximize the utility and benefit of our current information technology tools could impact our ability to meet cost reduction and planned efficiency and operational improvement goals.

Our income tax provision and other tax liabilities may be insufficient if taxing authorities are successful in asserting tax positions that are contrary to our position. Increases in tax rates could impact our financial performance.

From time to time, we are audited by various federal, state and local authorities regarding income tax matters. Significant judgment is required to determine our provision for income taxes and our liabilities for federal, state, local and other taxes. Although we believe our approach to determining the appropriate tax treatment is supportable and in accordance with relevant authoritative guidance it is possible that the final tax authority will take a tax position that is materially different than that which is reflected in our income tax provision. Such differences could have an adverse effect on our income tax provision or benefit, in the reporting period in which such determination is made and, consequently, on our results of operations, financial position and/or cash flows for such period. Further, future increases in tax rates may adversely affect our financial results.

Provisions in our organizational documents and Massachusetts law and other actions we have taken could make it more difficult for a third party to acquire us.

Provisions of our charter and by-laws could have the effect of discouraging a third party from making a proposal to acquire our company and could prevent certain changes in control, even if some shareholders might consider the proposal to be in their best interest. These provisions include a classified board of directors, advance notice to our board of directors of shareholder proposals and director nominations, and limitations on the ability of shareholders to remove directors and to call shareholder meetings. In addition, we may issue shares of any class or series of preferred stock in the future without shareholder approval

23

upon such terms as our board of directors may determine. The rights of holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any such class or series of preferred stock that may be issued.

We also are subject to the Massachusetts General Laws which, subject to certain exceptions, prohibit a Massachusetts corporation from engaging in a broad range of business combinations with any “interested shareholder” for a period of three years following the date that such shareholder becomes an interested shareholder. These provisions could discourage a third party from pursuing an acquisition of our company at a price considered attractive by many shareholders.

Our profits may decrease and/or we may incur significant unanticipated costs if we do not accurately estimate the costs of fixed-price engagements.

A significant number of our system integration projects are based on fixed-price contracts, rather than contracts in which payment to us is determined on a time and materials or other basis. Our failure to estimate accurately the resources and schedule required for a project, or our failure to complete our contractual obligations in a manner consistent with the project plan upon which our fixed-price contract was based, could adversely affect our overall profitability and could have a material adverse effect on our business, financial condition and results of operations. We are consistently entering into contracts for large projects that magnify this risk. We have been required to commit unanticipated additional resources to complete projects in the past, which has occasionally resulted in losses on those contracts. We will likely experience similar situations in the future. In addition, we may fix the price for some projects at an early stage of the project engagement, which could result in a fixed price that is too low. Therefore, any changes from our original estimates could adversely affect our business, financial condition and results of operations.

The trading price of our common stock may continue to be volatile, which may adversely affect our business, and investors in our common stock may experience substantial losses.

Our stock price, like that of other technology companies, has been volatile. The stock market in general and technology companies in particular may continue to experience volatility. The stock prices for companies in the defense technology industry may continue to remain volatile given the uncertainty and timing of funding for defense programs. This volatility may or may not be related to our operating performance. Our operating results, from time to time, may be below the expectations of public market analysts and investors, which could have a material adverse effect on the market price of our common stock. Our low stock trading volume and microcap status could hamper existing and new shareholders from gaining a meaningful position in our stock. In addition, the continued threat of terrorism in the United States and abroad and the resulting military action and heightened security measures undertaken in response to threats may cause continued volatility in securities markets. When the market price of a stock has been volatile, holders of that stock will sometimes issue securities class action litigation against the company that issued the stock. If any shareholders were to issue a lawsuit, we could incur substantial costs defending the lawsuit. Also, the lawsuit could divert the time and attention of management.

We have never paid dividends on our capital stock and we do not anticipate paying any dividends in the foreseeable future. Consequently, any gains from an investment in our common stock will likely depend on whether the price of our common stock increases.

We have not declared or paid cash dividends on any of our classes of capital stock to date and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future. Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the payment of dividends. Consequently, in the foreseeable future, you will likely only experience a gain from your investment in our common stock if the price of our common stock increases. There is no guarantee that our common stock will appreciate in value or even maintain the price at which you purchased your shares, and you may not realize a return on your investment in our common stock.

If our internal controls over financial reporting are not considered effective, our business and stock price could be adversely affected.

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal controls over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal controls over financial reporting in our annual report on Form 10-K for that fiscal year. Section 404 also requires our independent registered public accounting firm to attest to, and report on, management’s assessment of our internal controls over financial reporting.

Our management, including our chief executive officer and chief financial officer, does not expect that our internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a

24

control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become ineffective because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal controls in the future. A material weakness in our internal controls over financial reporting would require management and our independent registered public accounting firm to consider our internal controls as ineffective. If our internal controls over financial reporting are not considered effective, we may experience a loss of public confidence, which could have an adverse effect on our business and on the market price of our common stock.

If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our common stock, the price of our common stock could decline.

The trading market for our common stock relies in part on the research and reports that equity research analysts publish about us and our business. We do not control these analysts. The price of our common stock could decline if one or more equity analysts downgrade our common stock or if analysts issue other unfavorable commentary or cease publishing reports about us or our business.

We may need additional capital and may not be able to raise funds on acceptable terms, if at all. In addition, any funding through the sale of additional common stock or other equity securities could result in additional dilution to our stockholders and any funding through indebtedness could restrict our operations.

We may require additional cash resources to finance our continued growth or other future developments, including any investments or acquisitions we may decide to pursue. The amount and timing of such additional financing needs will vary principally depending on the timing of new product and service launches, investments and/or acquisitions, and the amount of cash flow from our operations. If our resources are insufficient to satisfy our cash requirements, we may seek to sell additional equity or debt securities or obtain a credit facility. The sale of additional equity securities or securities convertible into our ordinary shares could result in additional dilution to our stockholders. The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations.

Our ability to obtain additional capital on acceptable terms is subject to a variety of uncertainties, including:

• investors’ perception of, and demand for, securities of defense technology companies;

• conditions of the United States and other capital markets in which we may seek to raise funds; and

• our future results of operations, financial condition and cash flows.

We cannot assure that financing will be available in amounts or on terms acceptable to us, if at all. If we fail to raise additional funds, we may need to sell debt or additional equity securities or to reduce our growth to a level that can be supported by our cash flow. Without additional capital, we may not be able to:

• further develop or enhance our customer base;

• acquire necessary technologies, products or businesses;

• expand operations in the United States and elsewhere;

• hire, train and retain employees;

• market our software solutions, services and products; or

• respond to competitive pressures or unanticipated capital requirements.

(1) In our periodic communications, we discuss a key measure that is not calculated according to U.S. generally accepted accounting principles (“GAAP”), adjusted EBITDA. Adjusted EBITDA is defined as earnings from continuing operations before interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting and stock-based compensation costs. We use adjusted EBITDA as an important indicator of the operating performance of our business. We use adjusted EBITDA in internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to our board of directors, determining components of bonus and equity compensation for executive officers based on operating performance and evaluating short-term and long-term operating trends in our operations. We believe the adjusted EBITDA financial measure assists in providing a more complete understanding of our underlying operational measures to manage our business, to evaluate our performance compared to prior periods and the marketplace, and to establish operational goals. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in our financial and operational decision-making.

Adjusted EBITDA is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenses similar to the adjusted EBITDA financial adjustments described above, and investors should not infer from our presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring. See the Non-GAAP Financial Measures section of this annual report for a reconciliation of our adjusted EBITDA to income from continuing operations.

OVERVIEW

Mercury Systems, Inc. is a leading high-tech commercial provider of more affordable secure and sensor processing subsystems designed and made in U.S.A. powering today's critical defense and intelligence applications. We deliver innovative solutions, rapid time-to-value and service and support to our defense prime contractor customers. Our products and solutions have been deployed in more than 300 programs with over 25 different defense prime contractors. Key programs include Aegis, Patriot, Surface Electronic Warfare Improvement Program ("SEWIP"), Gorgon Stare, Predator, F-35 and Reaper. Our organizational structure allows the Company to deliver capabilities that combine technology building blocks and deep domain expertise in the defense sector. We believe our total portfolio of services and solutions is unique in the industry for a commercial company. We operate across a broad spectrum of defense programs and deliver our solutions and services via two operating segments: (i) Mercury Commercial Electronics; and (ii) Mercury Defense Systems. In the fourth quarter of fiscal 2014, we initiated a plan to divest our Mercury Intelligence Systems ("MIS") operating segment. Consequently, its operating results are included in discontinued operations for all periods presented. On January 23, 2015, we completed the sale of the MIS operating segment (see Note C to the consolidated financial statements).

As of June 30, 2015, we had 629 employees. Our revenue, income from continuing operations and adjusted EBITDA for fiscal 2015 were $234.8 million, $14.4 million, and $44.4 million, respectively. See the Non-GAAP Financial Measures section for a reconciliation of our income (loss) from continuing operations to adjusted EBITDA.

Our operations are organized in the following two reportable segments: (i) Mercury Commercial Electronics ("MCE") and (ii) Mercury Defense Systems ("MDS").

Mercury Commercial Electronics, or MCE, provides more affordable, innovative, commercially designed and developed, specialized processing subsystems for critical defense and intelligence applications. We deliver innovative solutions, rapid time-to-value and service and support to our prime defense contractor customers. Our technologies and capabilities include embedded processing modules and subsystems, radio frequency ("RF") and microwave multi-function assemblies as well as subsystems, and RF and microwave components.

MCE utilizes leading edge, high performance computing technologies architected by leveraging open standards and open architectures to address highly data-intensive applications that include signal, sensor and image processing; all of this while addressing the packaging challenges, often referred to as “SWaP” (size, weight, and power) that are common in military applications. In addition, MCE designs and builds RF and microwave components and subsystems to meet the needs of the electronic warfare ("EW"), signal intelligence ("SIGINT") and other high bandwidth communications requirements and applications.

In fiscal 2015, MCE accounted for 88% of our total net revenues.

Mercury Defense Systems, or MDS, provides significant capabilities relating to pre-integrated, open, more affordable EW, electronic attack ("EA") and electronic counter measure ("ECM") subsystems, and SIGINT and electro-optical/infrared ("EO/IR") processing technologies, and radar environment test and simulation systems. MDS deploys these solutions on behalf of defense prime contractors and the Department of Defense ("DoD"), leveraging commercially available technologies and solutions (or “building blocks”) from our MCE business and other commercial suppliers. MDS leverages this technology to develop integrated sensor processing subsystems, often including classified application-specific software and intellectual property ("IP") for the C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ECM markets. MDS brings significant domain expertise to customers, drawing on over 25 years of experience in EW, SIGINT, and radar environment test and simulation.

In fiscal 2015, MDS accounted for 12% of our total net revenues.

Since we are an OEM supplier to our commercial markets and conduct much of our business with our defense customers via commercial items, requests by customers are a primary driver of revenue fluctuations from quarter to quarter. Customers specify delivery date requirements that coincide with their need for our products. Because these customers may use our products in connection with a variety of defense programs or other projects of different sizes and durations, a customer’s orders for one quarter generally do not indicate a trend for future orders by that customer. Additionally, order patterns do not necessarily correlate amongst customers and, therefore, we generally cannot identify sequential quarterly trends, even within our operating segments.

BUSINESS DEVELOPMENTS:

FISCAL 2015

During fiscal 2015, we successfully completed the final phase of integration activities relating to our previous acquisitions. The acquisition integration plan included the consolidation of manufacturing facilities, centralization of administrative and manufacturing functions using common information systems and processes, and realignment of research and development

30

resources. Restructuring and other charges in fiscal 2015 amounted to $3.2 million and affected both the MCE and MDS reportable segments. We currently do not anticipate any future restructuring activities.

During fiscal 2015, we completed the sale of our former MIS operating segment. Since the fourth quarter of fiscal 2014, MIS has been reported as a discontinued operation for all periods presented.

FISCAL 2014

During fiscal 2014, we moved into our new manufacturing facility in Hudson, New Hampshire that will provide a platform for continued growth in our RF and microwave product lines. During the year, we consolidated four facilities into the new plant and installed integrated business systems that will allow us to scale our RF and microwave capabilities both organically and through merger and acquisition activities.

In fiscal 2014, we announced a restructuring plan ("2014 Plan") that was implemented as part of the final phase of integration activities relating to our recent acquisitions. The integration plan includes the consolidation of manufacturing facilities, centralization of administrative and manufacturing functions using common information systems and processes and rebalancing of research and development investments. The restructuring plan included the elimination of 70 positions largely in engineering, manufacturing and administrative functions. Additionally, we closed four facilities relocating all related activities to the Company's Advanced Microelectronics Center ("AMC") in Hudson, New Hampshire. During the fourth quarter of fiscal 2014, we also consolidated facilities at our corporate headquarters. These restructuring and other charges associated with our fiscal 2014 integration plan amounted to $5.4 million and affected both the MCE and MDS reportable segments.

FISCAL 2013

During the first quarter of fiscal 2013, we announced a restructuring plan ("Q1 2013 Plan") impacting primarily the MCE operating segment as a result of a significant decline in bookings and revenue. The plan consisted of the elimination of 142 positions primarily in engineering and support staff areas. Additionally, during the fourth quarter of fiscal 2013, as a result of the first phase of integration activities surrounding our recent acquisitions, we initiated a restructuring plan ("Q4 2013 Plan") that included the sale of our Hudson, New Hampshire facility and the elimination of 17 positions primarily in operations. We incurred restructuring and other charges of $7.1 million for the fiscal year ended June 30, 2013.

In fiscal 2013, we acquired Micronetics Inc., a leading designer and manufacturer of microwave and RF subsystems and components for defense and commercial customers. Revenue and net loss from continuing operations of Micronetics included in our consolidated statements of operations for fiscal 2013 were $35.5 million and $(3.8) million, respectively.

REVENUES

(In thousands)	Fiscal 2015		As a % of Total Net Revenue		Fiscal 2014			As a % of Total Net Revenue		$ Change			% Change
MCE	$	207,104	88	%	$	175,766		84	%	$	31,338		18	%
MDS	27,411		12	%	34,217			16	%	(6,806		)	(20	)%
Eliminations	332		—		(1,254		)	—		1,586			126	%
Total revenues	$	234,847	100	%	$	208,729		100	%	$	26,118		13	%

Total revenues increased $26.1 million, or 13%, to $234.8 million during fiscal 2015 compared to $208.7 million during fiscal 2014. The increase was driven by higher defense revenues of $28.4 million, partially offset by lower commercial sales of $2.3 million. The increase in total revenues is primarily attributed to increases in the F-35, Patriot, and SEWIP programs, partially offset by decreases in the Aegis and Gorgon Stare programs. International revenues, which consist of foreign military sales through prime defense contractor customers and direct sales to non-U.S. based customers, decreased by $6.0 million to $45.3 million during fiscal 2015 compared to $51.3 million during fiscal 2014. The decrease was primarily driven by lower international revenues in the Asia Pacific region. International revenues represented 19% and 25% of total revenues during fiscal 2015 and 2014, respectively.

Net MCE revenues increased $31.3 million, or 18%, during fiscal 2015 compared to fiscal 2014. The increase in net MCE revenues was primarily driven by higher defense revenues of $33.6 million, partially offset by lower commercial revenues of $2.3 million. This related to increases in the F-35, Patriot and SEWIP programs, partially offset by decreases in the Aegis program and lower commercial revenues of $2.3 million. Defense revenue accounted for 93% of net MCE revenues during fiscal 2015 compared to 90% in fiscal 2014.

Net MDS revenues decreased $6.8 million, or 20%, during fiscal 2015 compared to fiscal 2014. This decrease was primarily driven by lower revenues related to the Gorgon Stare program.

32

Eliminations revenue is attributable to development programs where the revenue is recognized in both segments under contract accounting, and reflects the reconciliation to our consolidated results.

GROSS MARGIN

Gross margin was 46.9% for fiscal 2015, an increase of 150 basis points from the 45.4% gross margin achieved in fiscal 2014. The higher gross margin in fiscal 2015 was due to a more favorable product mix, primarily driven by stronger revenues in our higher margin digital signal processing products within MCE.

SELLING, GENERALAND ADMINISTRATIVE

Selling, general and administrative expenses decreased $4.7 million, or 9%, to $49.0 million during fiscal 2015 as compared to $53.7 million during fiscal 2014. The decrease was primarily due to lower employee compensation expenses from completion of our acquisition integration plan. Selling, general and administrative expenses decreased as a percentage of revenue to 20.9% during fiscal 2015 from 25.7% during fiscal 2014 due to higher revenues in fiscal 2015 coupled with overall expense reductions, as compared to fiscal 2014.

RESEARCHAND DEVELOPMENT

Research and development expenses decreased $3.1 million, or 9%, to $32.6 million during fiscal 2015 compared to $35.7 million for fiscal 2014. The decrease was primarily due to $6.2 million of higher customer funded development and $0.3 million lower depreciation expense, partially offset by $2.2 million of increased employee compensation expenses. Research and development expenses accounted for 13.9% and 17.1% of our revenues during fiscal 2015 and fiscal 2014, respectively.

AMORTIZATIONOF INTANGIBLE ASSETS

Amortization of intangible assets decreased $0.3 million to $7.0 million during fiscal 2015 compared to $7.3 million for fiscal 2014, primarily due to a portion of the Micronetics' related intangible assets being fully amortized during the first quarter of fiscal 2014.

RESTRUCTURINGAND OTHER CHARGES

Restructuring and other charges decreased 42%, or $2.2 million, to $3.2 million during fiscal 2015 compared to $5.4 million in fiscal 2014. In fiscal 2014, we announced a restructuring plan that was implemented as part of the final phase of integration activities relating to our recent acquisitions. This acquisition integration plan included the consolidation of manufacturing facilities, centralization of administrative functions using common information systems and processes, and realignment of research and development resources. In fiscal 2015, our acquisition integration plan was completed and we incurred restructuring and other charges of $3.2 million affecting both the MCE and MDS reportable segments, but primarily associated with the final phases of the Chelmsford, Massachusetts headquarters consolidation and severance costs. We expect to realize approximately $16 million in annualized savings from these integration activities. In the event that we are unable to sublease the unoccupied portion of our headquarters complex in Chelmsford, Massachusetts, we will incur nominal, periodic restructuring charges through fiscal 2017 in our MCE reportable segment. We do not currently anticipate further restructuring activities after June 30, 2015.

The fiscal 2014 restructuring activities included the elimination of 70 positions largely in engineering, manufacturing and administrative functions. Additionally, in fiscal 2014 we closed four facilities, relocating all related activities to our Advanced Microelectronics Center ("AMC") in Hudson, New Hampshire and completed the first phase of our Chelmsford, Massachusetts headquarters consolidation.

ACQUISITION COSTSAND OTHER RELATED EXPENSES

We incurred $0.1 million of acquisition costs and other related expenses during fiscal 2015. We did not incur any acquisition costs and other related expenses during fiscal 2014. We expect to incur acquisition costs and other related expenses periodically as we continue to look for acquisition opportunities to expand our capabilities within RF, microwave, and embedded processing with a goal to assemble differentiated capabilities across the entire sensor processing chain.

OTHER INCOME, NET

Other income decreased $1.1 million to $0.4 million during fiscal 2015 compared to $1.5 million in fiscal 2014. The decrease was a result of foreign currency exchange losses during fiscal 2015 driven by the weakening Japanese yen against the U.S. dollar as compared to modest gains during fiscal 2014. In addition, other income in fiscal 2015 included $0.3 million of bank fees which were classified as selling, general, and administrative expenses in periods prior to the third quarter of fiscal 2015. Other income

included $1.2 million in amortization of the gain on the sale leaseback of our corporate headquarters located in Chelmsford, Massachusetts during fiscal 2015 and 2014. Interest income and interest expense for fiscal years 2015 and 2014 were de minimis.

INCOME TAXES

We recorded an income tax provision of $4.4 million in fiscal 2015 compared to an income tax benefit of $1.8 million in fiscal 2014. The effective tax rates for fiscal 2015 and fiscal 2014 were 23.2% and 31.1%, respectively.

Our effective tax rate for fiscal 2015 differed from the federal statutory rate primarily due to benefits related to research and development tax credits, domestic manufacturing deductions and releases of reserves for tax contingencies, partially offset by non-deductible equity compensation.

The difference in the effective tax rates is mainly driven by tax reserves released during fiscal 2015 as a result of the expiration of applicable statutes of limitations, tax rate changes recorded in fiscal 2015, and additional deductions for stock-based compensation in fiscal 2015 compared to a shortfall in fiscal 2014.

DISCONTINUED OPERATIONS

We incurred a loss from discontinued operations of $4.1 million in fiscal 2015 compared to a loss from discontinued operations of $7.4 million in fiscal 2014. The losses from discontinued operations included $2.3 million and $6.7 million impairments of goodwill in our MIS operating segment in fiscal 2015 and 2014, respectively. In addition, fiscal 2015 included a $0.9 million loss on disposal of discontinued operations before income taxes from the sale of our MIS operating segment, which we completed on January 23, 2015.

SEGMENT OPERATING RESULTS

We use adjusted EBITDA as the profitability measure for our segment reporting. Adjusted EBITDA for MCE increased $21.8 million to $40.3 million during fiscal 2015, as compared to $18.5 million during fiscal 2014. The increase in adjusted EBITDA was primarily driven by higher revenues of $31.3 million primarily from the Patriot, SEWIP, and F-35 programs, coupled with higher gross margins and lower selling, general and administrative costs from our restructuring initiatives completed in fiscal 2015.

Adjusted EBITDA for MDS decreased by $2.3 million during fiscal 2015 to $3.4 million, as compared to $5.7 million in fiscal 2014. The decrease in adjusted EBITDA was primarily driven by lower revenues from the Gorgon Stare program.

See Note P to our consolidated financial statements for more information regarding our operating segments as well as the Company's reconciliations of income (loss) from continuing operations to its adjusted EBITDA.

Total revenues	$	208,729		100	%	$	194,231	100	%	$	14,498		7	%

Total revenues increased $14.5 million, or 7%, to $208.7 million during fiscal 2014 compared to $194.2 million during fiscal 2013. The increase was driven by higher defense revenues of $16.9 million, partially offset by lower commercial sales of $2.4 million. The increase in total revenues is primarily attributed to a recovery in our higher margin digital signal processing products within MCE, specifically increases in the Aegis, Patriot, and UAV related programs, partially offset by decreases in the SEWIP program as well as MDS's DRFM jammer and Gorgon Stare programs. International revenues, which consist of foreign military sales through prime defense contractor customers and direct sales to non-U.S. based customers, decreased by $1.7 million to $51.3 million during fiscal 2014 compared to $53.0 million during fiscal 2013. The decrease was primarily driven by lower international revenues in the Asia Pacific region. International revenues represented 25% and 27% of total revenues during fiscal 2014 and 2013, respectively.

Net MCE revenues increased $23.2 million, or 15%, during fiscal 2014 compared to fiscal 2013. The increase in net MCE revenues was primarily driven by higher net defense revenues of $24.2 million, partially offset by lower commercial revenues of $2.4 million. The increase in net MCE defense revenues was driven by a recovery in our higher margin digital signal processing products, specifically increases in the Aegis, Patriot and UAV related programs, which were partially offset by decreases in the SEWIP and Navy Multiband Terminal ("NMT") programs. Defense revenue accounted for 90% of net MCE revenues during fiscal 2014 compared to 87% in fiscal 2013.

Net MDS revenues decreased $7.3 million, or 18%, during fiscal 2014 compared to fiscal 2013. This decrease was driven by the decreases in a DRFM jammer program and the Gorgon Stare program.

35

Eliminations revenue is attributable to development programs where the revenue is recognized in both segments under contract accounting, and reflects the reconciliation to our consolidated results.

GROSS MARGIN

Gross margin was 45.4% for fiscal 2014, an increase of 520 basis points from the 40.2% gross margin achieved in fiscal 2013. The higher gross margin in fiscal 2014 was due to a more favorable product mix, primarily driven by a recovery in our higher margin digital signal processing products within MCE and facilities consolidations as part of our integration plan. In addition, fiscal 2013 included a $2.1 million non-recurring charge for a fair value adjustment from purchase accounting resulting from the Micronetics acquisition.

SELLING, GENERALAND ADMINISTRATIVE

Selling, general and administrative expenses decreased $1.1 million, or 2%, to $53.7 million during fiscal 2014 compared to $54.8 million during fiscal 2013. The overall decrease was primarily due to lower employee compensation expenses as a result of progress achieved on our plan of integrating and consolidating facilities, systems, and processes. Selling, general and administrative expenses decreased as a percentage of revenue to 25.7% during fiscal 2014 from 28.2% during fiscal 2013 due to higher revenues in fiscal 2014 and overall expense reductions, as compared to the comparable period in fiscal 2013.

RESEARCHAND DEVELOPMENT

Research and development expenses increased $3.1 million, or 9.5%, to $35.7 million during fiscal 2014 compared to $32.6 million for fiscal 2013. The increase was primarily due to $0.8 million lower customer funded projects, $0.9 million higher prototype expenses, and $2.0 million increased employee compensation expenses, including stock compensation expense. Research and development expenses accounted for 17.1% and 16.8% of our revenues during fiscal 2014 and fiscal 2013, respectively. These increases were partially offset by lower depreciation expenses.

AMORTIZATIONOF INTANGIBLE ASSETS

Amortization of intangible assets decreased $0.9 million, or 11%, to $7.3 million during fiscal 2014 compared to $8.2 million for fiscal 2013, primarily due to a portion of the Micronetics related intangible assets being fully amortized during the first quarter of fiscal 2014.

RESTRUCTURINGAND OTHER CHARGES

Restructuring and other charges decreased 23%, or $1.6 million, to $5.4 million during fiscal 2014 compared to $7.1 million in fiscal 2013. The fiscal 2014 restructuring activities included the elimination of 70 positions largely in engineering, manufacturing and administrative functions. Additionally, we closed four facilities relocating all related activities to our Advanced Microelectronics Center ("AMC") in Hudson, New Hampshire. We also completed the first phase of our Chelmsford, Massachusetts headquarters consolidation in the fourth quarter of fiscal 2014. Future restructuring expenses associated with the integration plan approximated $3.2 million in fiscal 2015.We expect to realize approximately $16 million in annualized savings from the fiscal 2014 cost reduction activities, which was completed in the second quarter of fiscal 2015.

The restructuring plans implemented during fiscal 2013 consisted of $5.5 million of involuntary separation costs related to the reduction in force which eliminated 159 positions, primarily from our engineering, administrative, and manufacturing functions, and $1.4 million in facility charges for our Hudson, New Hampshire, Huntsville, Alabama, and Ewing, New Jersey sites. Our fiscal 2013 restructuring plans were implemented to cope with reduced defense revenues and the uncertainties in the defense industry driven by the potential for defense budget sequestration. Additionally, fiscal 2013 activities were implemented as a result of integration efforts of recent acquisitions and the planned consolidation of our manufacturing facilities in Salem, New Hampshire and Hudson, New Hampshire.

ACQUISITION COSTSAND OTHER RELATED EXPENSES

We did not incur any acquisition costs and other related expenses during fiscal 2014. During fiscal 2013, we incurred $0.3 million of acquisition costs and other related expenses, in connection with the acquisition of Micronetics.

OTHER INCOME, NET

Other income increased $1.0 million to $1.5 million during fiscal 2014 compared to $0.5 million in fiscal 2013. The increase was a result of foreign currency exchange gains during fiscal 2014 compared to losses during fiscal 2013 primarily driven by changes in the Japanese yen versus the U.S. dollar. Other income included $1.2 million in amortization of the gain on the sale

36

leaseback of our corporate headquarters located in Chelmsford, Massachusetts during fiscal 2014 and 2013. Interest income and interest expense for fiscal years 2014 and 2013 were de minimis.

INCOME TAXES

We recorded an income tax benefit of $1.8 million in fiscal 2014 compared to an income tax benefit of $10.5 million in fiscal 2013. The effective tax rates for fiscal 2014 and fiscal 2013 were 31.1% and 43.2%, respectively.

Our effective tax rate for fiscal 2014 differed from the federal statutory rate primarily due to non-deductible equity compensation, partially offset by benefits related to research and development tax credits, domestic manufacturing deductions and foreign tax credits.

The difference in the effective tax rates is mainly driven by fiscal 2014 including only six-months of federal research and development tax credits compared to 18 months in fiscal 2013 due to the timing of the tax credit extension and lower non-deductible stock compensation in fiscal 2013.

DISCONTINUED OPERATIONS

We incurred a loss from discontinued operations of $7.4 million in fiscal 2014 compared to income from discontinued operations of $0.5 million in fiscal 2013. The loss from discontinued operations in fiscal 2014 includes a $6.7 million impairment of goodwill in our MIS operating segment.

SEGMENT OPERATING RESULTS

Adjusted EBITDA for MCE increased $15.7 million to $18.5 million during fiscal 2014, as compared to $2.8 million during fiscal 2013. The increase in adjusted EBITDA was primarily driven by higher revenues of $23.2 million primarily from an increase in revenues from our higher margin digital signal processing products.

Adjusted EBITDA for MDS decreased by $1.4 million during fiscal 2014 to $5.7 million, as compared to $7.1 million in fiscal 2013. The decrease is primarily driven by lower revenues from the DRFM jammer and Gorgon Stare programs.

See Note P to our consolidated financial statements for more information regarding our operating segments as well as the Company's reconciliations of income (loss) from continuing operations to its adjusted EBITDA.

LIQUIDITY AND CAPITAL RESOURCES

During fiscal 2015, our primary source of liquidity came from existing cash and cash generated from operations. Our near-term fixed commitments for cash expenditures consist primarily of payments under operating leases and inventory purchase commitments with our contract manufacturers. We do not currently have any material commitments for capital expenditures.

Based on our current plans and business conditions, we believe that existing cash, cash equivalents, available line of credit, cash generated from operations, and financing capabilities will be sufficient to satisfy our anticipated cash requirements for at least the next twelve months.

Shelf Registration Statement

On August 15, 2014, we filed a shelf registration statement on Form S-3 with the SEC. The shelf registration statement, which has been declared effective by the SEC, registered up to $500 million of debt securities, preferred stock, common stock, warrants and units. We intend to use the proceeds from a financing using the shelf registration statement for general corporate purposes, which may include the following:

• the acquisition of other companies or businesses;

• the repayment and refinancing of debt;

• capital expenditures;

• working capital; and

• other purposes as described in the prospectus supplement.

Senior Unsecured Credit Facility

On October 12, 2012, we entered into a credit agreement (the “Credit Agreement”) with a syndicate of commercial banks, with KeyBank National Association acting as the administrative agent. The Credit Agreement provides for a $200.0 million senior unsecured revolving line of credit (the “Revolver”). We can borrow up to $200.0 million based on our consolidated EBITDA for the prior trailing four quarters and subject to compliance with the financial covenants discussed below. The Revolver is available

37

for working capital, acquisitions, and general corporate purposes of the Company and its subsidiaries. The Revolver is available for borrowing during a five year period, with interest payable periodically during such period as provided in the Credit Agreement and principal due at the maturity of the Revolver.

The Credit Agreement has an accordion feature permitting us to request from the lenders an increase in the aggregate amount of the credit facility in the form of an incremental revolver or term loan in an amount not to exceed $50.0 million. Any such increase would require only the consent of the lenders increasing their respective commitments under the credit facility.

The interest rates applicable to borrowings under the Credit Agreement involve various rate options that are available to us. The rates are calculated using a combination of conventional base rate measures plus a margin over those rates. The base rates consist of LIBOR rates or prime rates. The actual rates will depend on the level of these underlying rates plus a margin based on our leverage at the time of borrowing.

Borrowings under the Credit Agreement are senior unsecured loans. Each of our domestic subsidiaries is a guarantor under the Credit Agreement.

The Credit Agreement provides for conventional affirmative and negative covenants, including a maximum leverage ratio of 3.50x and a minimum interest coverage ratio of 3.0x. Each of the two ratios referred to above is calculated based on consolidated EBITDA, as defined in the Credit Agreement, on a consolidated basis for each consecutive four fiscal quarter period, after giving pro forma effect for any acquisitions or dispositions. Acquisitions are permitted under the Credit Agreement without any dollar limitation so long as, among other requirements, no default or event of default exists or would result. In addition, the Credit Agreement contains certain customary representations and warranties, and events of default.

As of June 30, 2015, there was $151.5 million of borrowing capacity available based on our consolidated EBITDA for the trailing four quarters ended June 30, 2015. There were no borrowings outstanding on the Credit Agreement; however, there were outstanding letters of credit of $3.8 million. We were in compliance with all covenants and conditions under the Credit Agreement.

CASH FLOWS

(In thousands) As of and for the fiscal year ended	June 30, 2015			June 30, 2014			June 30, 2013
Net cash provided by (used in) operating activities	$	32,207		$	14,241		$	(1,871	)
Net cash used in investing activities	$	(5,598	)	$	(6,720	)	$	(71,091	)
Net cash provided by (used in) financing activities	$	3,905		$	742		$	(3,669	)
Net increase (decrease) in cash and cash equivalents	$	30,299		$	8,161		$	(76,838	)
Cash and cash equivalents at end of year	$	77,586		$	47,287		$	39,126

Our cash and cash equivalents increased by $30.3 million during fiscal 2015 primarily as a result of $32.2 million in cash generated by operating activities, partially offset by $6.0 million in purchases of property and equipment.

Operating Activities

During fiscal 2015, we generated $32.2 million in cash from operating activities, an increase of $18.0 million when compared to $14.2 million in cash generated from operating activities in fiscal 2014. The increase in cash generated by operating activities was primarily a result of $21.8 million of higher comparable net income, $18.4 million increase in accounts receivable collections, and $4.5 million generated from lower deferred income taxes. The increase in cash generated from operating activities was partially offset by a $11.8 million increase in cash used for prepaid expenses and other current assets, $6.2 million in higher inventory purchases, and a $4.4 million decrease in non-cash activity from the impairment of goodwill associated with our MIS discontinued operations. Our ability to generate cash from operations in future periods will depend in large part on profitability, the rate and timing of collections of accounts receivable, our inventory turns and our ability to manage other areas of working capital.

During fiscal 2014, we generated $14.2 million in cash from operating activities, an increase of $16.1 million when compared to $1.9 million in cash used in operating activities in fiscal 2013. The increase in cash generated by operating activities was primarily a result of $1.8 million of lower comparable net loss, a $14.3 million decrease in cash used for payables and accrued expenses, a $6.7 million increase in non-cash activity from the impairment of goodwill associated with the MIS discontinued operations, $4.6 million generated from lower deferred income taxes, and $5.4 million in lower inventory purchases. The increase in cash generated from operating activities was partially offset by timing of accounts receivable collections of $17.2 million.

38

Investing Activities

During fiscal 2015, we used cash of $5.6 million in investing activities compared to $6.7 million used during fiscal 2014. Driving the $1.1 million decrease in cash used in investing activities were fewer purchases of property and equipment of $0.7 million and proceeds generated from the sale of our MIS operating segment of $0.9 million.

During fiscal 2014, we used cash of $6.7 million in investing activities compared to $71.1 million used during fiscal 2013. The $64.4 million decrease in cash used in investing activities was primarily driven by $67.7 million used for the Micronetics acquisition in fiscal 2013, partially offset by increased capital expenditures of $2.8 million in fiscal 2014.

Financing Activities

During fiscal 2015, we generated $3.9 million from financing activities compared to $0.7 million cash generated from financing activities during fiscal 2014. The $3.2 million change in cash from financing activities was primarily due to a $3.1 million increase in proceeds from employee stock plans and $0.9 million increase in excess tax benefit from stock-based compensation compared to fiscal 2014, partially offset by $0.9 million of retired common stock.

During fiscal 2014, we generated $0.7 million from financing activities compared to $3.7 million cash used in financing activities during fiscal 2013. The $4.4 million change in cash from financing activities was primarily due to a $6.6 million payment to settle debt acquired as part of the Micronetics acquisition, partially offset by the release of $3.0 million of restricted cash both of which occurred during fiscal 2013.

COMMITMENTSAND CONTRACTUAL OBLIGATIONS

The following is a schedule of our commitments and contractual obligations outstanding at June 30, 2015:

(In thousands)	Total		Less Than 1 Year		2-3 Years		4-5 Years		More Than 5 Years
Operating leases	$	21,398	$	4,536	$	5,931	$	3,784	$	7,147
Purchase obligations	$	27,376	27,376		—		—		—
Capital lease obligations	$	—	—		—		—		—
	$	48,774	$	31,912	$	5,931	$	3,784	$	7,147

We have a liability at June 30, 2015 of $1.5 million for uncertain tax positions that have been taken or are expected to be taken in various income tax returns. We do not know the ultimate resolution of these uncertain tax positions and as such, do not know the ultimate timing of payments related to this liability. Accordingly, these amounts are not included in the above table.

Purchase obligations represent open non-cancelable purchase commitments for certain inventory components and services used in normal operations. The purchase commitments covered by these agreements are for less than one year and aggregated $27.4 million at June 30, 2015.

Our standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which we indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with certain intellectual property infringement claims by any third party with respect to our products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments we could be required to make under these indemnification provisions is, in some instances, unlimited.

In connection with the sale of our former MIS business, we provided indemnification to the buyer of the business. Our indemnification obligations generally cover the buyer for damages resulting from breaches of representations, warranties and covenants contained in the purchase and sale agreement and generally cover pre-closing tax liabilities of the business. Our indemnification obligations regarding the MIS business are generally subject to caps.

As part of our strategy for growth, we continue to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed.

We may elect from time to time to purchase and subsequently retire shares of common stock in order to settle an individual employees’ tax liability associated with vesting of a restricted stock award. These transactions would be treated as a use of cash in financing activities in our statement of cash flows.

39

OFF-BALANCE SHEET ARRANGEMENTS

Other than our lease commitments incurred in the normal course of business and certain indemnification provisions, we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not consolidated in the financial statements. Additionally, we do not have an interest in, or relationships with, any special purpose entities.

RELATED PARTY TRANSACTIONS

During fiscal 2015 and 2014, we did not engage in any related party transactions.

NON-GAAP FINANCIAL MEASURES

In our periodic communications, we discuss two important measures that are not calculated according to U.S. generally accepted accounting principles (“GAAP”), adjusted EBITDA and free cash flow.

Adjusted EBITDA is defined as earnings from continuing operations before interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting and stock-based compensation expense. We use adjusted EBITDA as an important indicator of the operating performance of our business. We use adjusted EBITDA in internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to our board of directors, determining a component of bonus and equity compensation for executive officers based on operating performance and evaluating short-term and long-term operating trends in our operations. We believe the adjusted EBITDA financial measure assists in providing a more complete understanding of our underlying operational measures to manage our business, to evaluate our performance compared to prior periods and the marketplace, and to establish operational goals. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in our financial and operational decision-making.

Adjusted EBITDA is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenses similar to the adjusted EBITDA financial adjustments described above, and investors should not infer from our presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring.

The following table reconciles our income (loss) from continuing operations, the most directly comparable GAAP financial measure, to our adjusted EBITDA:

	Year Ended June 30,
(In thousands)	2015		2014			2013
Income (loss) from continuing operations	$	14,429	$	(4,072	)	$	(13,782	)

Tax provision (benefit)	4,366		(1,841		)	(10,501		)
Depreciation	6,332		7,625			8,445
Amortization of intangible assets	7,008		7,328			8,222
Restructuring and other charges	3,175		5,443			7,060
Impairment of long-lived assets	—		—			—
Acquisition and financing costs	451		—			318
Fair value adjustments from purchase accounting	—		—			2,293
Stock-based compensation expense	8,640		8,999			7,854
Adjusted EBITDA	$	44,414	$	23,522		$	9,940

Free cash flow, a non-GAAP measure for reporting cash flow, is defined as cash provided by operating activities less capital expenditures for property and equipment, which includes capitalized software development costs. We believe free cash flow provides investors with an important perspective on cash available for investments and acquisitions after making capital investments required to support ongoing business operations and long-term value creation. We believe that trends in our free cash flow are valuable indicators of our operating performance and liquidity.

40

Free cash flow is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenditures similar to the free cash flow adjustment described above, and investors should not infer from our presentation of this non-GAAP financial measure that these expenditures reflect all of our obligations which require cash.

The following table reconciles cash provided by operating activities, the most directly comparable GAAP financial measure, to free cash flow:

	Year Ended June 30,
(In thousands)	2015			2014			2013
Cash provided by (used in) operating activities	$	32,207		$	14,241		$	(1,871	)
Purchases of property and equipment	(5,984		)	(6,701		)	(3,880		)
Free cash flow	$	26,223		$	7,540		$	(5,751	)

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

We have identified the policies discussed below as critical to understanding our business and our results of operations. The impact and any associated risks related to these policies on our business operations are discussed throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations where such policies affect our reported and expected financial results. We believe the following critical accounting policies to be those most important to the portrayal of our financial position and results of operations and those that require the most subjective judgment.

REVENUE RECOGNITION

We recognize revenue using three different types of accounting methods: ship and bill, multiple-deliverable arrangements and contract accounting which encompass the percentage of completion, completed contract and time and materials methods. Ship and bill revenues, multiple-deliverable arrangements and contract accounting revenues totaled 47%, 24%, and 29% of total Company revenues in fiscal 2015, respectively.

Revenue from system sales is recognized upon shipment utilizing the ship and bill method provided that title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, have been successfully demonstrated.

For multiple-deliverable revenue arrangements that may include a combination of hardware components, related integration or other services, we allocate revenue to each deliverable based on its relative fair value. We generally determine relative selling price using best estimate of the selling price (“BESP”). We determine BESP for each deliverable using a bottoms-up cost plus expected margin approach. Each deliverable within our multiple-deliverable revenue arrangement is accounted for as a separate unit of accounting if the delivered item or items have value to the customer on a standalone basis. We consider a deliverable to have standalone value if the item is sold separately by us or another vendor or if the item could be resold by the customer.

We also have long term production type contracts that are primarily fixed-price for which we apply the percentage-of-completion method for revenue recognition. These long-term contracts involve the design, development, manufacture, or modification of complex electronic equipment and related services. Under this method, revenue is recognized based on the extent of progress towards completion of the long-term contract.

Application of the percentage-of-completion method requires significant judgment relative to estimating total contract costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, labor productivity, anticipated increases in wages and prices for subcontractor services and materials, the availability of our subcontractor’s services and materials, the availability and timing of funding from our customer, and overhead rates, among other variables. We primarily use the cost-to-cost measure of progress for our long-term contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the contracts. Our estimates are based upon the professional knowledge and experience of our engineers, program managers and finance professionals, who review each long-term contract monthly to assess the contract's schedule, performance, technical matters and estimated cost at completion.

A cancellation, schedule delay, or modification of a fixed-price contract which is accounted for using the percentage-of-completion method may adversely affect our gross margins for the period in which the contract is modified or canceled. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods. For time and materials contracts, revenue reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well

41

as reimbursement of other billable direct costs. The completed contract method is utilized when reasonable and reliable cost estimates for a project cannot be made.

Our analysis of these contracts also contemplates whether contracts should be combined or segmented in accordance with the applicable criteria under GAAP. We combine closely related contracts when all the applicable criteria under GAAP are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single project, which should be combined to reflect an overall profit rate. Similarly, we may segment a project, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria under GAAP are met. Judgment also is involved in determining whether a single contract or group of contracts may be segmented based on how arrangement was negotiated and the performance criteria. The decision to combine a group of contracts or segment a contract could change the amount of revenue and gross profit recorded in a given period. For all types of contracts, we recognize anticipated contract losses as soon as they become known and estimable. These losses are recognized in advance of contract performance and as of June 30, 2015, approximately $1.1 million of these costs were in accrued expenses on our balance sheet.

We do not provide our customers with rights of product return, other than those related to warranty provisions that permit repair or replacement of defective goods. We accrue for anticipated warranty costs upon product shipment. Our payment terms generally range from 30 to 90 days from invoice date based on the nature of the contracts, customers' geographic locations and customer type.

We define service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold by us. Examples of our service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. We combine our product and service revenues into a single class as services revenues are less than 10 percent of total revenues.

INVENTORY VALUATION

We value our inventory at the lower of cost (first-in, first-out) or its current estimated market value. We write down inventory for excess and obsolescence based upon assumptions about future demand, product mix and possible alternative uses. Actual demand, product mix and alternative usage may be lower than those that we project and this difference could have a material adverse effect on our gross margin if inventory write-downs beyond those initially recorded become necessary. Alternatively, if actual demand, product mix and alternative usage are more favorable than those we estimated at the time of such a write-down, our gross margin could be favorably impacted in future periods.

GOODWILL, INTANGIBLE ASSETSAND LONG-LIVED ASSETS

We evaluate our goodwill for impairment annually in the fourth quarter and in any interim period in which events or circumstances arise that indicate our goodwill may be impaired. Indicators of impairment include, but are not limited to, a significant deterioration in overall economic conditions, a decline in our market capitalization, the loss of significant business, significant decreases in funding for our contracts, or other significant adverse changes in industry or market conditions. In the second quarter of fiscal 2015, the sale process of our MIS reporting unit was well underway and there were indications that the market value of MIS would not support its carrying value. This resulted in an interim triggering event. As a result of the fair value analysis, we incurred a $2.3 million impairment charge for the MIS business recorded in discontinued operations during the second quarter of fiscal 2015. There were no interim triggering events for MCE or MDS.

We test goodwill for impairment at the reporting unit level. Goodwill impairment guidance provides entities an option to perform a qualitative assessment (commonly known as “step zero”) to determine whether further impairment testing is necessary before performing the two-step test. The qualitative assessment requires significant judgments by management about macro-economic conditions including the entity's operating environment, its industry and other market considerations, entity-specific events related to financial performance or loss of key personnel, and other events that could impact the reporting unit. If we conclude that further testing is required, the impairment test involves a two-step process. Step one compares the fair value of the reporting unit with its carrying value, including goodwill. If the carrying amount exceeds the fair value of the reporting unit, step two is required to determine if there is an impairment of the goodwill. Step two compares the implied fair value of the reporting unit's goodwill to the carrying amount of the goodwill. The Company estimates the fair value of its reporting units using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues, expenses, capital expenditures, and working capital, as well as discount factors and income tax rates. In addition, the Company uses the market approach, which compares the reporting unit to publicly-traded companies and transactions involving similar businesses, to support the conclusions of the income approach.

As part of our annual goodwill impairment testing performed on May 31, 2015, we utilized the income approach to determine the fair value of our MCE and MDS reporting units. As part of our annual goodwill impairment testing, we utilized a discount rate for each of our reporting units that we believe represents the risks that our businesses face, considering their sizes, the current economic environment, and other industry data we believe is appropriate. The discount rates for MCE and MDS were 10% and

42

13%, respectively. The annual testing indicated that the fair values of our MCE and MDS reporting units significantly exceeding their carrying values, and thus no further testing was required. A one percent change in the discount rate of either reporting unit would still result in significant excess of fair value over carrying value.

We also review finite-lived intangible assets and long-lived assets when indications of potential impairment exist, such as a significant reduction in undiscounted cash flows associated with the assets. Should the fair value of our long-lived assets decline because of reduced operating performance, market declines, or other indicators of impairment, a charge to operations for impairment may be necessary.

INCOME TAXES

The determination of income tax expense requires us to make certain estimates and judgments concerning the calculation of deferred tax assets and liabilities, as well as the deductions and credits that are available to reduce taxable income. We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse.

In evaluating our ability to recover deferred tax assets, we consider all available positive and negative evidence, including our past operating results, our forecast of future earnings, future taxable income, and tax planning strategies. The assumptions utilized in determining future taxable income require significant judgment. We record a valuation allowance against deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. If it becomes more likely than not that a tax asset will be used for which a reserve has been provided, we reverse the related valuation allowance. If our actual future taxable income by tax jurisdiction differs from estimates, additional allowances or reversals of reserves may be necessary.

We use a two-step approach to recognize and measure uncertain tax positions. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. We reevaluate our uncertain tax positions on a quarterly basis and any changes to these positions as a result of tax audits, tax laws or other facts and circumstances could result in additional charges to operations.

BUSINESS COMBINATIONS

We utilized the acquisition method of accounting for business combinations and allocate the purchase price of an acquisition to the various assets acquired and liabilities assumed based on their estimated fair values. We primarily establish fair value using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues and expenses, as well as discount factors and income tax rates.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us on July 1, 2018 and can be early adopted for the fiscal year beginning July 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on its ongoing financial reporting.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, an amendment of the FASB Accounting Standards Codification. The ASU has added additional disclosure requirements to the codification. It requires management to assess, at each interim and annual reporting period, whether substantial doubt exists about the company’s ability to continue as a going concern. Substantial doubt exists if it is probable (the “probable” threshold under US GAAP has generally been interpreted to be between 75 and 80 percent) that the company will be unable to meet its obligations as they become due within one year after the date the financial statements are issued or available to be issued (assessment date). The ASU is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter, with early adoption permitted. We do not expect a going concern uncertainty in the foreseeable future, and therefore this guidance is not expected to have a material impact to our consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-17, Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force), an amendment of the FASB Accounting Standards Codification. This ASU allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply

43

pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. As this guidance is applicable to separate financial statements of acquired entities, we do not expect this guidance to have a material impact to our consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, an amendment of the FASB Accounting Standards Codification. This ASU eliminates the separate presentation of extraordinary items, net of tax and the related earnings per share, but does not affect the requirement to disclose material items that are unusual in nature or infrequently occurring. The ASU aligns U.S. GAAP more closely with IFRS ("International Financial Reporting Standards"). Entities will continue to evaluate whether items are unusual in nature or infrequent in their occurrence for disclosure purposes and when estimating the annual effective tax rate for interim reporting purposes. This ASU is effective for interim and annual periods in fiscal years beginning after December 15, 2015. The ASU allows prospective or retrospective applications. Early adoption is permitted if applied from the beginning of the fiscal year of adoption. We do not expect this guidance to have a material impact to our consolidated financial statements.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 1, 2014, we adopted FASB ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, an amendment of the FASB Accounting Standards Codification. The ASU requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist and certain criteria are met. Such adoption did not have a material impact to our consolidated financial statements.

Effective October 1, 2014, we adopted FASB ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), an amendment of the FASB Accounting Standards Codification. The ASU clarifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity's operations and financial results. Additionally, the amendments in this ASU require expanded disclosure for discontinued operations to provide users with more information about the assets, liabilities, revenues, and expenses. Such adoption did not have a material impact to our consolidated financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

Our exposure to interest rate risk is related primarily to our investment portfolio and our line of credit. Our investment portfolio includes money market funds from high quality U.S. government issuers. A change in prevailing interest rates may cause the fair value of our investments to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing rate rises, the fair value of the principal amount of our investment will probably decline. To minimize this risk, investments are generally available for sale and we generally limit the amount of credit exposure to any one issuer. Our line of credit was used to support $3.8 million of letters of credit at June 30, 2015.

FOREIGN CURRENCY RISK

We operate primarily in the United States; however, we conduct business outside the United States through our foreign subsidiaries in Europe and Japan, where business is largely transacted in non-U.S. dollar currencies. Accordingly, we are subject to exposure from adverse movements in the exchange rates of local currencies. Local currencies are used as the functional currency for our subsidiaries in Europe and Japan. Consequently, changes in the exchange rates of the currencies may impact the translation of the foreign subsidiaries’ statements of operations into U.S. dollars, which may in turn affect our consolidated statement of operations.

We have not entered into any financial derivative instruments that expose us to material market risk, including any instruments designed to hedge the impact of foreign currency exposures. We may, however, hedge such exposure to foreign currency exchange rate fluctuations in the future.

REPORTOF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Mercury Systems, Inc.:

We have audited the accompanying consolidated balance sheets of Mercury Systems, Inc. and subsidiaries as of June 30, 2015 and 2014, and the related consolidated statements of operations, comprehensive income (loss), shareholders’ equity, and cash flows for each of the years in the three-year period ended June 30, 2015. In connection with our audits of the consolidated financial statements, we also have audited financial statement schedule II. We also have audited Mercury Systems, Inc.’s internal control over financial reporting as of June 30, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Mercury Systems, Inc.’s management is responsible for these consolidated financial statements and financial statement Schedule II, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Controls Over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule and an opinion on the Company’s internal control over financial reporting 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 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.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Mercury Systems, Inc. and subsidiaries as of June 30, 2015 and 2014, and the results of their operations and their cash flows for each of the years in the three-year period ended June 30, 2015, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. Also in our opinion, Mercury Systems, Inc. maintained, in all material respects, effective internal control over financial reporting as of June 30, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

MERCURY SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except per share data)

A.Description of Business

Mercury Systems, Inc. (the “Company” or “Mercury”) is a leading high-tech commercial provider of more affordable secure and sensor processing subsystems designed and made in the U.S.A. powering today's critical defense and intelligence applications. The Company delivers innovative solutions, rapid time-to-value and service and support to its defense prime contractor customers. The Company's products and solutions have been deployed in more than 300 programs with over 25 different defense prime contractors. Key programs include Aegis, Patriot, Surface Electronic Warfare Improvement Program ("SEWIP"), Gorgon Stare, Predator, F-35 and Reaper. The Company's organizational structure allows it to deliver capabilities that combine technology building blocks and deep domain expertise in the defense sector.

The Company's goal is to grow and build on its position as a critical component of the defense industrial base and become the leading provider of open and more affordable secure and sensor processing subsystems. The Mercury Commercial Electronics (“MCE”) operating segment designs, develops and builds open sensor processing products and subsystems that include embedded processing modules and subsystems, radio frequency (“RF”) and microwave multi-function assemblies as well as subsystems, and RF and microwave components. The Mercury Defense Systems (“MDS”) operating segment provides significant capabilities relating to pre-integrated, open, more affordable electronic warfare ("EW"), electronic attack ("EA") and electronic counter measure ("ECM") subsystems and significant capabilities in signals intelligence ("SIGINT"), and electro-optical/infrared ("EO/IR") processing technologies and radar environment test and simulation systems.

In June 2014, the Company initiated a plan to divest the Mercury Intelligence Systems (“MIS”) operating segment, based on the Company's strategic direction and investment priorities focusing on its core business. As a result, the Company's MIS operating segment met the “held for sale” criteria in accordance with Financial Accounting Standard Boards (“FASB”) Accounting Standards Codification (“ASC”) 205, Presentation of Financial Statements, (“FASB ASC 205”) as of June 30, 2014 (see Note C to consolidated financial statements). The consolidated financial statements, excluding the statements of shareholders' equity and cash flows, and the notes to the consolidated financial statements were restated for all periods presented to reflect the discontinuation of the MIS operating segment, in accordance with FASB ASC 205. On January 23, 2015, the Company completed the sale of the MIS operating segment.

B. Summary of Significant Accounting Policies

PRINCIPLESOF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under FASB ASC 805, Business Combinations, (“FASB ASC 805”), for all transactions and events which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as measurement date for all assets and liabilities assumed. The Company also utilizes FASB ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

USEOF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

REVENUE RECOGNITION

The Company relies upon FASB ASC 605, Revenue Recognition, to account for its revenue transactions. Revenue is recognized upon shipment provided that title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, have been successfully demonstrated. Out-of-pocket expenses that are reimbursable by the customer are included in revenue and cost of revenue.

50

Certain contracts with customers require the Company to perform tests of its products prior to shipment to ensure their performance complies with the Company’s published product specifications and, on occasion, with additional customer-requested specifications. In these cases, the Company conducts such tests and, if they are completed successfully, includes a written confirmation with each order shipped. As a result, at the time of each product shipment, the Company believes that no further customer testing requirements exist and that there is no uncertainty of acceptance by its customer.

The Company uses FASB Accounting Standards Update (“ASU”) No. 2009-13 (“FASB ASU 2009-13”), Multiple-Deliverable Revenue Arrangements. FASB ASU 2009-13 establishes a selling price hierarchy for determining the selling price of a deliverable, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third-party evidence (“TPE”) if VSOE is not available; and (3) best estimated selling price (“BESP”), if neither VSOE nor TPE is available. Additionally, FASB ASU 2009-13 expands the disclosure requirements related to a vendor’s multiple-deliverable revenue arrangements. 

The Company enters into multiple-deliverable arrangements that may include a combination of hardware components, related integration or other services. These arrangements generally do not include any performance-, cancellation-, termination- or refund-type provisions.

In accordance with the provisions of FASB ASU 2009-13, the Company allocates arrangement consideration to each deliverable in an arrangement based on its relative selling price. The Company generally expects that it will not be able to establish VSOE or TPE due to limited single element transactions and the nature of the markets in which the Company competes, and, as such, the Company typically determines its relative selling price using BESP.

The Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact if the product or service were sold by the Company on a standalone basis.

The Company’s determination of BESP involves the consideration of several factors based on the specific facts and circumstances of each arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, the Company’s ongoing pricing strategy and policies (as evident from the price list established and updated by management on a regular basis), the value of any enhancements that have been built into the deliverable and the characteristics of the varying markets in which the deliverable is sold.

The Company analyzes the selling prices used in its allocation of arrangement consideration at a minimum on an annual basis. Selling prices will be analyzed on a more frequent basis if a significant change in the Company’s business necessitates a more timely analysis or if the Company experiences significant variances in its selling prices.

Each deliverable within the Company’s multiple-deliverable revenue arrangements is accounted for as a separate unit of accounting under the guidance of FASB ASU 2009-13 if both of the following criteria are met: the delivered item or items have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The Company’s revenue arrangements generally do not include a general right of return relative to delivered products. The Company considers a deliverable to have standalone value if the item is sold separately by the Company or another vendor or if the item could be resold by the customer.

Deliverables not meeting the criteria for being a separate unit of accounting are combined with a deliverable that does meet that criterion. The appropriate allocation of arrangement consideration and recognition of revenue is then determined for the combined unit of accounting.

The Company also engages in long-term contracts for development, production and services activities which it accounts for consistent with FASB ASC 605-35, Accounting for Performance of Construction-Type and Certain Production-Type Contracts, and other relevant revenue recognition accounting literature. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. Generally for fixed-price contracts, other than service-type contracts, revenue is recognized primarily under the percentage of completion method or, for certain short-term contracts, by the completed contract method. Revenue from service-type fixed-price contracts is recognized ratably over the contract period or by other appropriate input or output methods to measure service provided, and contract costs are expensed as incurred. The Company establishes billing terms at the time project deliverables and milestones are agreed. Revenues recognized in excess of the amounts invoiced to clients are classified as unbilled receivables. The risk to the Company on a fixed-price contract is that if estimates to complete the contract change from one period to the next, profit levels will vary from period to period. For time and materials contracts, revenue reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well as reimbursement of other billable direct costs. For all types of contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable.

The Company also considers whether contracts should be combined or segmented in accordance with the applicable criteria under GAAP. The Company combines closely related contracts when all the applicable criteria under GAAP are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single project, which should be combined to reflect an overall profit rate. Similarly, the Company may

51

separate a project, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria under GAAP are met. Judgment also is involved in determining whether a single contract or group of contracts may be segmented based on how the arrangement was negotiated and the performance criteria. The decision to combine a group of contracts or segment a contract could change the amount of revenue and gross profit recorded in a given period.

The use of contract accounting requires significant judgment relative to estimating total contract revenues and costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, anticipated increases in wages and prices for subcontractor services and materials, and the availability of subcontractor services and materials. The Company’s estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods.

Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. The Company records revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. Assumed recoveries for claims included in contracts in process were not material at June 30, 2015 or 2014.

The Company defines service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold. Examples of the Company's service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. The Company combines its product and service revenues into a single class as service revenues are less than 10 percent of total revenues.

The Company does not provide its customers with rights of product return, other than those related to warranty provisions that permit repair or replacement of defective goods. The Company accrues for anticipated warranty costs upon product shipment. Revenues from product royalties are recognized upon invoice by the Company. Additionally, all revenues are reported net of government assessed taxes (e.g. sales taxes or value-added taxes).

CASHAND CASH EQUIVALENTS

Cash equivalents, consisting of highly liquid money market funds and U.S. government and U.S. government agency issues with original maturities of 90 days or less at the date of purchase, are carried at fair market value which approximates cost.

RESTRICTED CASH

The Company had restricted cash balances of $264 and $265 as of June 30, 2015 and 2014, respectively. The balances are classified as restricted cash on the accompanying consolidated balance sheet and are reflected in non-current assets. The balances at June 30, 2015 and 2014 included restrictions related to certain contracts with foreign customers that require a certificate of deposit to be held at a commercial bank until performance of the contracts have been completed.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, restricted cash and contingent consideration. FASB ASC 820, Fair Value Measurement and Disclosures, specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

CONCENTRATIONOF CREDIT RISK

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions that management believes are of high credit quality. At June 30, 2015 and 2014, the Company had $77,586 and $47,287, respectively, of cash and cash equivalents on deposit or invested with its financial and lending institutions.

52

The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. At June 30, 2015, five customers accounted for 55% of the Company's receivables, unbilled receivables and costs in excess of billings. At June 30, 2014, five customers accounted for 55% of the Company’s receivables, unbilled receivables and costs in excess of billings.

INVENTORY

Inventory is stated at the lower of cost (first-in, first-out) or market value, and consists of materials, labor and overhead. On a quarterly basis, the Company evaluates inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand and non-cancelable on-order inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, product mix and possible alternative uses.

GOODWILLAND INTANGIBLE ASSETS

Goodwill is the amount by which the cost of the net assets obtained in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase. Goodwill is not amortized in accordance with the requirements of FASB ASC 350, Intangibles-Goodwill and Other (“FASB ASC 350”). Goodwill is assessed for impairment at least annually, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

Intangible assets result from the Company’s various business acquisitions (see Note H) and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, customer relationships, trademarks, backlog, and non-compete agreements. Intangible assets are reported at cost, net of accumulated amortization and are either amortized on a straight-line basis over their estimated useful lives of up to seven years or over the period the economic benefits of the intangible asset are consumed.

LONG-LIVED ASSETS

Long-lived assets primarily include property and equipment and acquired intangible assets. The Company regularly evaluates its long-lived assets for events and circumstances that indicate a potential impairment in accordance with FASB ASC 360, Property, Plant, and Equipment (“FASB ASC 360”). The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value.

Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and are not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Equipment under capital lease is recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method (see Note F).

As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

Expenditures for major software purchases and software developed for internal use are capitalized and depreciated using the straight-line method over the estimated useful lives of the related assets, which are generally three years. For software developed for internal use, all external direct costs for material and services and certain payroll and related fringe benefit costs are capitalized in accordance with FASB ASC 350. During fiscal 2015, 2014 and 2013, the Company capitalized $0, $362 and $91 of software development costs.

DEFERRED REVENUESAND CUSTOMER ADVANCES

Deferred revenues consist of deferred product revenue, billings in excess of revenues, and deferred service revenue. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because one or more of the conditions for revenue recognition have not been met. Billings in excess of revenues represents milestone billing arrangements on percentage of completion projects where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty concessions, which are recognized ratably over the term of the arrangements. Customer advances represent deposits received from customers on an order.

53

INCOME TAXES

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“FASB ASC 740”). The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse. The Company records a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

FASB ASC 740 requires a two-step approach to recognizing and measuring uncertain tax positions. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

PRODUCT WARRANTY ACCRUAL

The Company’s product sales generally include a 12 month standard hardware warranty. At time of product shipment, the Company accrues for the estimated cost to repair or replace potentially defective products. Estimated warranty costs are based upon prior actual warranty costs for substantially similar transactions and any specifically identified warranty requirements. Product warranty accrual is included as part of accrued expenses in the accompanying consolidated balance sheets. The following table presents the changes in the Company's product warranty accrual.

	Fiscal 2015			Fiscal 2014			Fiscal 2013
Beginning balance at July 1,	$	2,078		$	2,522		$	1,360
Warranty assumed from Micronetics acquisition	—			—			245
Accruals for warranties issued during the period	1,465			1,951			4,592
Settlements made during the period	(1,569		)	(2,395		)	(3,675		)
Ending balance at June 30,	$	1,974		$	2,078		$	2,522

RESEARCHAND DEVELOPMENT COSTS

Research and development costs are expensed as incurred. Research and development costs are primarily made up of labor charges and prototype material and development expenses.

STOCK-BASED COMPENSATION

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. Stock-based compensation expense for the Company’s performance-based restricted stock awards are amortized over the requisite service period using graded vesting. The company’s other restricted stock awards recognize expense over the requisite service period on a straight-line basis. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options.

RETIREMENT OF COMMON STOCK

Stock that is repurchased or received in connection with the exercise of stock options or in order to cover tax payment obligations triggered by exercise of stock options or the vesting of restricted stock is retired immediately upon the Company’s repurchase. The Company accounts for this under the cost method and upon retirement the excess amount over par value is charged against additional paid-in capital.

NET EARNINGS PER SHARE

Basic net earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net earnings per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method. For all periods presented, income (loss) from continuing operations is the control number for determining whether securities are dilutive or not.

54

Basic and diluted weighted average shares outstanding were as follows:

	Years Ended June 30,
	2015	2014	2013
Basic weighted-average shares outstanding	32,114	31,000	30,128
Effect of dilutive equity instruments	825	—	—
Diluted weighted-average shares outstanding	32,939	31,000	30,128

Equity instruments to purchase 453, 3,526 and 4,077 shares of common stock were not included in the calculation of diluted net earnings per share for the fiscal years ended June 30, 2015, 2014 and 2013, respectively, because the equity instruments were anti-dilutive.

ACCUMULATED OTHER COMPREHENSIVE INCOME

Accumulated other comprehensive income includes foreign currency translation adjustments and unrealized gains on investments. The components of accumulated other comprehensive income were $776 and $1,011 of accumulated foreign currency translation adjustments at June 30, 2015 and 2014. There were no material accumulated net unrealized gains on investments at June 30, 2015 and 2014.

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Europe and Japan. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in accumulated other comprehensive income in shareholders’ equity. Gains (losses) resulting from foreign currency transactions are included in other income (expense) and were immaterial for all periods presented.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on July 1, 2018 and can be early adopted for the fiscal year beginning July 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, an amendment of the FASB Accounting Standards Codification. The ASU has added additional disclosure requirements to the codification. It requires management to assess, at each interim and annual reporting period, whether substantial doubt exists about the Company’s ability to continue as a going concern. Substantial doubt exists if it is probable (the “probable” threshold under U.S. GAAP has generally been interpreted to be between 75 and 80 percent) that the Company will be unable to meet its obligations as they become due within one year after the date the financial statements are issued or available to be issued (assessment date). The ASU is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not expect a going concern uncertainty in the foreseeable future, and therefore this guidance is not expected to have a material impact to its consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-17, Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force), an amendment of the FASB Accounting Standards Codification. This ASU allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. As this guidance is applicable to separate financial statements of acquired entities, the Company does not expect this guidance to have a material impact to its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, an amendment of the FASB Accounting Standards Codification. This ASU eliminates the separate presentation of extraordinary items, net of tax and the related earnings per share, but does not affect the requirement to disclose material items that are unusual in nature or infrequently occurring. The ASU aligns U.S. GAAP more closely with IFRS (International Financial Reporting Standards). Entities will continue to evaluate whether items are unusual in nature or infrequent in their occurrence for disclosure purposes and when estimating the annual effective tax rate for interim reporting purposes. This ASU is effective for interim and annual periods in fiscal years beginning after December 15, 2015. The ASU allows prospective

55

or retrospective applications. Early adoption is permitted if applied from the beginning of the fiscal year of adoption. The Company does not expect this guidance to have a material impact to its consolidated financial statements.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 1, 2014, the Company adopted FASB ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, an amendment of the FASB Accounting Standards Codification. The ASU requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist and certain criteria are met. Such adoption did not have a material impact to the Company's consolidated financial statements.

Effective October 1, 2014, the Company adopted FASB ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), an amendment of the FASB Accounting Standards Codification. The ASU clarifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity's operations and financial results. Additionally, the amendments in this ASU require expanded disclosure for discontinued operations to provide users with more information about the assets, liabilities, revenues, and expenses. Such adoption did not have a material impact to the Company's consolidated financial statements.

C.Discontinued Operations

During the fourth quarter of fiscal 2014, the Company conducted a strategic review of the Mercury Intelligence Systems (“MIS”) operating segment which encompassed an assessment of MIS' financial performance and contemporaneous future financial projections. The Company, with Board of Director's approval, concluded that a plan to divest the MIS operating segment would be in the best interests of the Company and its shareholders. On January 23, 2015, the Company completed the sale of MIS.

In fiscal 2014, the Company's MIS operating segment met the "held for sale" criteria in accordance with FASB ASC 205. As the Company did not anticipate continuing involvement in the operations of MIS after its divestiture, the MIS operating results had been reported as a discontinued operation for all periods presented.

The classification as "held for sale" was considered a triggering event for impairment testing under FASB ASC 350 and FASB ASC 360. However, since the Company conducted its annual goodwill impairment testing in its fourth quarter of fiscal 2014, which coincided with the plan to divest the MIS operating segment, the “held for sale” triggering event did not constitute a separate goodwill impairment test under FASB ASC 350 (see Note H). The triggering event, however, did require separate impairment testing of the MIS asset group’s long-lived assets under FASB ASC 360.

The goodwill impairment testing conducted in the fourth quarter of fiscal 2014 determined the MIS reporting unit's carrying value of goodwill exceeded its implied fair value, resulting in a $6,687 impairment charge. The impairment charge is reflected within discontinued operations of the Company's accompanying consolidated financial statements. The failure of the first step of the goodwill impairment test was driven by a decline in forecasted results of the MIS reporting unit. The fair value of the MIS reporting unit from the first step of the goodwill impairment test exceeded the fair value of the assets and liabilities of the MIS reporting unit, as determined by the second step of the goodwill impairment test. Testing of the valuation of long-lived assets of the MIS asset group indicated no impairment, as the estimated undiscounted cash flows of the MIS asset group, less estimated costs to sell, significantly exceeded its carrying value.

MIS was considered its own operating segment and was previously aggregated with MDS into one reportable segment based on similar economic and qualitative factors in accordance with FASB ASC 280. As MIS became a discontinued operation in the fourth quarter of fiscal 2014, the results of MIS had been excluded from the MDS reportable segment.  Accordingly, the revenues, costs of revenue, operating expenses, assets and liabilities of MIS have been reported separately as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) and Consolidated Balance Sheets for all periods presented. The discontinued operation's balances in the Consolidated Balance Sheets do not reflect intercompany receivable balances of MIS, and the results of discontinued operations do not reflect interest expense or the allocation of the Company's corporate general and administrative expenses.

During the second quarter of fiscal 2015, the Company determined that the MIS reporting unit's carrying value of goodwill exceeded its implied fair value, resulting in a further goodwill impairment charge of $2,283. This impairment charge is reflected within discontinued operations of the Company's accompanying fiscal 2015 consolidated financial statements.

On January 23, 2015, the Company completed the sale of MIS for approximately $1,600. The sale resulted in net proceeds of $885 and a loss on disposal of $892, which is reflected within discontinued operations of the Company's accompanying consolidated financial statements. The Company does not have continuing involvement in the operations of MIS after its divestiture.

D. Fair Value of Financial Instruments

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at June 30, 2015:

	Fair Value Measurements
	June 30, 2015		Level 1		Level 2		Level 3
Assets:
Operating cash	$	47,586	$	47,586	$	—	$	—
Certificates of deposit	30,000		—		30,000		—
Restricted cash	264		264		—		—
Cost-method investment	500		—		—		500
Total	$	78,350	$	47,850	$	30,000	$	500

The carrying values of cash and cash equivalents, including U.S. Treasury bills and money market funds, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities. The value of the certificates of deposit is based on the quoted price for identical or similar instruments in markets that are not active or are directly or indirectly observable. The cost-method investment does not have a readily determinable fair value, as such the Company recorded the investment as a long term asset at cost and will continue to evaluate the asset for impairment.

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at June 30, 2014:

	Fair Value Measurements
	June 30, 2014		Level 1		Level 2		Level 3

F. Property and Equipment

Property and equipment consisted of the following:

	Estimated Useful Lives (Years)	June 30,
		2015			2014
Computer equipment and software	2-4	$	58,562		$	55,881
Furniture and fixtures	5	7,614			7,556
Leasehold improvements	lesser of estimated useful life or lease term	4,003			3,758
Machinery and equipment	5	16,383			14,159
		86,562			81,354
Less: accumulated depreciation		(73,336		)	(67,210		)
		$	13,226		$	14,144

In fiscal 2015 and 2014, the Company retired $733 and $715, respectively, of fully depreciated computer equipment and software assets that were no longer in use by the Company. 

Depreciation expense related to property and equipment for the fiscal years ended June 30, 2015, 2014 and 2013 was $6,332, $7,625 and $8,445, respectively.

On June 27, 2013, the Company entered into a sales agreement and a separate short-term lease agreement in connection with the Company’s legacy Hudson, New Hampshire, facility. Pursuant to the sale agreement, the Company sold all land, land improvements, buildings and building improvements related to the facility. The loss on the sale of the facility was approximately $1,091 and is recorded in restructuring and other charges in the accompanying consolidated statement of operations.

On April 20, 2007, the Company entered into a sales agreement and a lease agreement in connection with a sale-leaseback of the Company’s headquarters in Chelmsford, Massachusetts. Pursuant to the agreements, the Company sold all land, land improvements, buildings and building improvements related to the facilities and leased back those assets. The term of the lease is ten years and includes twofive year options to renew. Under the provisions of sale-leaseback accounting, the transaction was considered a normal leaseback; thus the realized gain of $11,569 was deferred and will be amortized to other income on a straight-line basis over the initial lease term.

The unamortized deferred gain consisted of the following of which the current portion is included in accrued expenses and the non-current portion is separately classified in the accompanying consolidated balance sheets:

	June 30,
	2015		2014
Current portion	$	1,156	$	1,156
Non-current portion	929		2,086
Total unamortized deferred gain	$	2,085	$	3,242

G.Goodwill

The following table summarizes the changes in goodwill for the years ended June 30, 2014 and 2015:

	MCE		MDS		Total
Balance at June 30, 2013	$	133,783	$	33,768	$	167,551
Goodwill adjustments during fiscal 2014	595		—		595
Balance at June 30, 2014 and 2015	$	134,378	$	33,768	$	168,146

In accordance with FASB ASC 350 Intangibles-Goodwill and Other “FASB ASC 350”, the Company determines its reporting units based upon whether discrete financial information is available, if management regularly reviews the operating results of the component, the nature of the products offered to customers and the market characteristics of each reporting unit. A reporting unit is considered to be an operating segment or one level below an operating segment also known as a component. MCE has four components with discrete financial information available which are reviewed by their segment manager; however, those four components are economically similar in nature and thus have been aggregated into a single reporting unit at the operating segment level. MDS is a sole component and the reporting unit is at the operating segment level. The Company determined that its reporting units are the same as its operating segments, MCE and MDS.

59

As defined by FASB ASC 350, goodwill is tested for impairment on an interim basis at the occurrence of certain triggering events or at a minimum on an annual basis. In fiscal 2015, there were no triggering events from continuing operations which required an interim goodwill impairment test.

The Company follows FASB ASC 350 in assessing whether the fair value of a reporting unit is less than its carrying amount. As of June 30, 2015, both MCE and MDS had goodwill balances and the annual impairment analysis was performed for each reporting unit in the fourth quarter of fiscal 2015. The results of the Company's step one interim goodwill impairment test indicated that the fair values of the MCE and MDS reporting units were substantially in excess of their carrying values. As such, step two of the goodwill impairment testing was not required. Consistent with prior years, the valuation was based upon a discounted cash flow analysis and corroborated by a market-based analysis which compares the trading multiples of public companies in similar lines of business.

H. Intangible Assets

Intangible assets consisted of the following:

	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Weighted Average Useful Life
June 30, 2015
Customer relationships	$	33,880	$	(17,364	)	$	16,516	6.8 years

	Year Ending June 30,
2016	$	6,523
2017	5,041
2018	4,304
2019	1,760
2020	370
Total future amortization expense	$	17,998

I.Restructuring

During fiscal 2015, the Company incurred restructuring and other charges of $3,175, which affected both MCE and MDS reportable segments as the Company completed its acquisition integration plan. Additionally, during the fourth quarter of fiscal 2015, the Company eliminated 16 positions, primarily in operations, in the MCE reportable segment.

During fiscal 2014, the Company announced a restructuring plan ("2014 Plan") that was implemented as part of the final phase of integration activities relating to the Company’s recent acquisitions. The acquisition integration plan included the consolidation of manufacturing facilities, centralization of administrative functions using common information systems and processes, and realignment of research and development resources. The acquisition integration plan included the elimination of 70 positions largely in engineering, manufacturing and administrative functions. Additionally, the Company closed four facilities relocating all related activities to the Company's Advanced Microelectronics Center ("AMC") in Hudson, New Hampshire. The

60

Company also completed the first phase of the Chelmsford, Massachusetts headquarters consolidation in the fourth quarter of fiscal 2014. These restructuring and other charges associated with the Company's fiscal 2014 restructuring plan amounted to $5,443 and affected both MCE and MDS reportable segments. In the event that the Company is unable to sublease the unoccupied portion of its headquarters complex in Chelmsford, Massachusetts, it will incur nominal, periodic restructuring charges through fiscal 2017 in its MCE reportable segment.

All of the restructuring and other charges are classified as operating expenses in the consolidated statements of operations and any remaining severance obligations are expected to be paid within the next twelve months. The remaining restructuring liability is classified as accrued expenses in the consolidated balance sheets.

The following table presents the detail of expenses by reportable segment for the Company’s restructuring plans:

	Severance & Related			Facilities & Other			Total
Restructuring liability at June 30, 2013	$	434		$	286		$	720

	$	10,574		$	9,683

At June 30, 2015, the Company evaluated the need for a valuation allowance on deferred tax assets. In assessing whether the deferred tax assets are realizable, management considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the Company's past operating results, its forecast of future earnings, future taxable income, and tax planning strategies. The Company continues to conclude that it is more likely than not that most domestic deferred tax assets would be realizable based on the financial performance in fiscal year 2015, projected future taxable income and the reversal of existing deferred tax liabilities.

The Company continues to record a full valuation allowance on certain state research and development (“R&D”) and investment tax credits, and capital loss carryforwards as of June 30, 2015 as management continues to believe that it is not more likely than not that these deferred tax assets would be realized. Any future reversals of the valuation allowance will impact income tax expense.

The Company had federal research and development credit carryforwards of $959, which will expire from 2032 through 2033. The Company had state research and development credit carryforwards of $14,899, which will expire from 2016 through 2029. The Company also had state investment tax credits carryforwards of $404.

Upon consideration of changing business conditions and cash position in its foreign subsidiaries, management has determined that it does not need to indefinitely reinvest the earnings of certain foreign subsidiaries. Therefore, the Company has accrued deferred taxes in association with $672 in undistributed earnings and profits.

The Company files income tax returns in all jurisdictions in which it operates. The Company has established reserves to provide for additional income taxes that management believes will more likely than not be due in future years as these previously filed tax returns are audited. These reserves have been established based upon management’s assessment as to the potential exposures. All tax reserves are analyzed quarterly and adjustments are made as events occur and warrant modification.

63

The changes in the Company’s reserves for unrecognized income tax benefits are summarized as follows:

	Year Ended June 30,
	2015			2014
Unrecognized tax benefits, beginning of period	$	3,142		$	2,923
Increases for previously recognized positions	123			102
Reductions as a result of a lapse of the applicable statue of limitations	(1,197		)	(166		)
Increases for currently recognized positions	122			283
Unrecognized tax benefits, end of period	$	2,190		$	3,142

The $2,190 of unrecognized tax benefits as of June 30, 2015, if released, would reduce income tax expense.

The Company’s major tax jurisdiction is the U.S. and the open tax years are fiscal 2011 through 2015.

The Company is currently under audit by the Internal Revenue Service for fiscal year 2013. There have been no significant changes to the status of this examination during the year ended June 30, 2015. It is reasonably possible that within the next 12 months the Company’s unrecognized tax benefits, exclusive of interest, may decrease by up to $757 at the conclusion of the audit. We expect that the decrease, if recognized, would not affect the effective tax rate.

K.Commitments and Contingencies

LEGAL CLAIMS

The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of our business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company's cash flows, results of operations, or financial position.

INDEMNIFICATION OBLIGATIONS

The Company's standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company's products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited.

In connection with the sale of the Company’s former MIS business, the Company provided indemnification to the buyer of the business. The Company’s indemnification obligations generally cover the buyer for damages resulting from breaches of representations, warranties and covenants contained in the purchase and sale agreement and generally cover pre-closing tax liabilities of the business. The Company’s indemnification obligations regarding the MIS business are generally subject to caps.

PURCHASE COMMITMENTS

As of June 30, 2015, the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $27,376.

64

LEASE COMMITMENTS

The Company leases certain facilities, machinery and equipment under various cancelable and non-cancelable operating leases that expire at various dates through fiscal 2025. The leases contain various renewal options. Rental charges are subject to escalation for increases in certain operating costs of the lessor. For tenant improvement allowances and rent holidays, the Company records a deferred rent liability on the consolidated balance sheets and amortizes the deferred rent over the terms of the leases as reductions to rent expense on the consolidated statements of operations. Rental expense during the fiscal years ended June 30, 2015, 2014, and 2013 was $3,777, $4,213 and $4,167, respectively. Minimum lease payments under the Company’s non-cancelable operating leases are as follows:

	Year Ending June 30,
2016	$	4,536
2017	3,997
2018	1,934
2019	2,047
2020	1,737
Thereafter	7,147
Total minimum lease payments	$	21,398

L.Debt

SENIOR UNSECURED CREDIT FACILITY

On October 12, 2012, the Company entered into a credit agreement (the “Credit Agreement”) with a syndicate of commercial banks, with KeyBank National Association acting as the administrative agent. The Credit Agreement provides for a $200,000 senior unsecured revolving line of credit (the “Revolver”). The Company can borrow up to $200,000 based on its consolidated EBITDA for the prior trailing four quarters and subject to compliance with the financial covenants discussed below. The Revolver is available for working capital, acquisitions, and general corporate purposes of the Company and its subsidiaries. The Revolver is available for borrowing during a five year period, with interest payable periodically during such period as provided in the Credit Agreement and principal due at the maturity of the Revolver.

The Credit Agreement has an accordion feature permitting the Company to request from the lenders an increase in the aggregate amount of the credit facility in the form of an incremental revolver or term loan in an amount not to exceed $50,000. Any such increase would require only the consent of the lenders increasing their respective commitments under the credit facility.

The interest rates applicable to borrowings under the Credit Agreement involve various rate options that are available to the Company. The rates are calculated using a combination of conventional base rate measures plus a margin over those rates. The base rates consist of LIBOR rates or prime rates. The actual rates will depend on the level of these underlying rates plus a margin based on the Company's leverage at the time of borrowing.

Borrowings under the Credit Agreement are senior unsecured loans. Each of the Company's domestic subsidiaries is a guarantor under the Credit Agreement.

The Credit Agreement provides for conventional affirmative and negative covenants, including a maximum leverage ratio of 3.50x and a minimum interest coverage ratio of 3.0x. Each of the two ratios referred to above is calculated based on consolidated EBITDA, as defined in the Credit Agreement, for each consecutive four fiscal quarter period, after giving pro forma effect for any acquisitions. Acquisitions are permitted under the Credit Agreement without any dollar limitation so long as, among other requirements, no default or event of default exists or would result. In addition, the Credit Agreement contains certain customary representations and warranties, and events of default.

As of June 30, 2015, there was $151,549 of borrowing capacity available based on our consolidated EBITDA for the trailing four quarters ended June 30, 2015. There were no borrowings outstanding on the Credit Agreement; however, there were outstanding letters of credit of $3,839. As of June 30, 2015, the Company is in compliance with the covenants in the Credit Agreement.

On October 21, 2014, the Company's number of shares authorized for issuance under the 2005 Plan increased by 3,406 shares, including 3,200 shares approved by the Company's shareholders at the 2014 Annual Meeting of Shareholders and 206 shares as a result of forfeitures, cancellations and/or terminations from the Company's 1997 Stock Option Plan (the "1997 Plan"). The 2005 Plan will be increased by any future cancellations, forfeitures or terminations (other than by exercise) under the 1997 Plan. The 2005 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. All stock options are granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant and the options generally have a term of seven years. There were 3,648 shares available for future grant under the 2005 Plan at June 30, 2015.

The number of shares authorized for issuance under the 1997 Plan was 8,650 shares, of which 100 shares could be issued pursuant to restricted stock grants. The 1997 Plan provided for the grant of non-qualified and incentive stock options and restricted stock to employees and non-employees. All stock options were granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant. The options typically vest over periods of zero to four years and have a maximum term of 10 years. Following shareholder approval of the 2005 Plan on November 14, 2005, the Company’s Board of Directors determined that no further grants of stock options or other awards would be made under the 1997 Plan, and the 1997 Plan subsequently expired in June 2007. The foregoing does not affect any outstanding awards under the 1997 Plan, which remain in full force and effect in accordance with their terms.

On August 15, 2014, as part of the Company's ongoing annual equity grant program for employees, the Company granted performance-based restricted stock awards to certain executives pursuant to the 2005 Plan. These performance awards vest annually over a three year requisite service period subject to the achievement of specific financial performance targets related to adjusted EBITDA as a percentage of revenue. Based on the performance targets, these awards require graded vesting that results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic compensation expense accordingly.

EMPLOYEE STOCK PURCHASE PLAN

The number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 1,400 shares. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. The number of shares issued under the ESPP during fiscal years 2015, 2014, and 2013 was 79, 92 and 104, respectively. Shares available for future purchase under the ESPP totaled 85 at June 30, 2015.

STOCK-BASED COMPENSATION EXPENSEAND ASSUMPTIONS

The Company recognized the full expense of its share-based payment plans in the consolidated statements of operations for the fiscal years 2015, 2014, and 2013 in accordance with FASB ASC 718 and did not capitalize any such costs on the consolidated balance sheets, as such costs that qualified for capitalization were not material. Under the fair value recognition provisions of

67

FASB ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period. The following table presents share-based compensation expenses from continuing operations included in the Company’s consolidated statement of operations:

	Year Ended June 30,
	2015			2014			2013
Cost of revenues	$	493		$	601		$	371
Selling, general and administrative	6,751			7,024			6,436
Research and development	1,396			1,374			1,047
Share-based compensation expense before tax	8,640			8,999			7,854
Income taxes	(3,332		)	(3,420		)	(2,877		)
Share-based compensation expense, net of income taxes	$	5,308		$	5,579		$	4,977

There were no options granted during fiscal years 2015 or 2014. The only stock options granted during fiscal year 2013 were related to the Micronetics stock option rollover at the acquisition date. The following table sets forth the weighted-average key assumptions and fair value results for stock options granted during fiscal years 2015, 2014 and 2013:

	Years Ended June 30,
	2015			2014			2013
Weighted-average fair value of options granted	$	—		$	—		$	3.80
Option life(1)	—			—			4.5
Risk-free interest rate(2)	—		%	—		%	0.73		%
Stock volatility(3)	—		%	—		%	58		%
Dividend rate	—		%	—		%	—		%

(1) The option life was determined based upon historical option activity.

(2) The risk-free interest rate for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

(3) The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Company’s common stock over the most recent period equal to the expected option life of the grant, the historical short-term trend of the option and other factors, such as expected changes in volatility arising from planned changes in the Company’s business operations.

P.Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. The Company utilizes the management approach for determining reportable segments in accordance with the authoritative guidance. The following operating segments were determined based upon the nature of the products offered to customers, the market characteristics of each operating segment and the Company's management structure:

• Mercury Commercial Electronics (“MCE”): this operating segment delivers more affordable, innovative, commercially developed, specialized processing subsystems powering today's critical defense and intelligence applications. MCE delivers secure solutions that are based upon open architectures and widely adopted industry standards. MCE delivers rapid time-to-value and service and support to prime defense contractors and commercial customers. MCE provides solutions to prime contractor customers on a variety of programs. MCE also provides technology building blocks to Mercury Defense Systems on key classified and unclassified programs. MCE has a legacy of embedded multi-computing and embedded sensor processing expertise. More recently, MCE has added substantial capabilities around radio frequency ("RF") and microwave technologies as well as emerging new manufacturing capabilities to bring design, production and test capabilities of its RF and microwave solutions to market on a more scalable basis.

• Mercury Defense Systems (“MDS”): this operating segment provides significant capabilities relating to pre-integrated, open, more affordable electronic warfare ("EW"), electronic attack ("EA") and electronic counter measure ("ECM") subsystems, and signals intelligence ("SIGINT") and electro-optical/infrared ("EO/IR") processing technologies and radar environmental test and simulation systems. MDS deploys these solutions on behalf of defense prime contractors and the Department of Defense ("DoD"), leveraging commercially available technologies and solutions (or “building blocks”) from the MCE business and other commercial suppliers. MDS leverages this technology to develop integrated sensor processing subsystems, often including classified application-specific software and intellectual property ("IP") for the

68

C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ECM markets. MDS brings significant domain expertise to customers, drawing on over 25 years of experience in EW, SIGINT, and radar environment test and simulation.

The Company's operating segments were evaluated in accordance with FASB ASC 280 “Segment Reporting” in order to determine which operating segments qualified as reportable segments. The Company determined that both MCE and MDS met the quantitative thresholds for reporting.

The accounting policies of the reportable segments are the same as those described in “Note B: Summary of Significant Accounting Policies.” The profitability measure employed by the Company and its CODM as the basis for allocating resources to segments and assessing segment performance is adjusted EBITDA. The Company believes the adjusted EBITDA financial measure assists in providing an enhanced understanding of its underlying operational measures to manage its business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals.

Adjusted EBITDA is defined as income from continuing operations before interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting and stock-based compensation costs. Additionally, asset information by reportable segment is not reported because the Company and its CODM utilize consolidated asset information when making business decisions. The following is a summary of the performance of the Company's operations by reportable segment:

ITEM 9A.CONTROLS AND PROCEDURES

(a) EFFECTIVENESSOF DISCLOSURE CONTROLSAND PROCEDURES

We conducted an evaluation as of June 30, 2015 under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), and concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended, the “Exchange Act”) were effective as of June 30, 2015 and designed to ensure that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

(b) INHERENT LIMITATIONSON EFFECTIVENESSOF CONTROLS

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our internal control over financial reporting or our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

(c) MANAGEMENT’S ANNUAL REPORTON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision of the Chief Executive Officer and Chief Financial Officer, management conducted an assessment of the effectiveness of our internal control over financial reporting as of June 30, 2015 based on the framework in Internal Control-Integrated Framework (2013) published by the Committee of Sponsoring Organizations of the Treadway Commission. As a result of this assessment, management concluded that our internal control over financial reporting was effective as of June 30, 2015. The effectiveness of our internal control over financial reporting as of June 30, 2015 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in its report.

(d) CHANGESIN INTERNAL CONTROL OVER FINANCIAL REPORTING

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of fiscal 2015 identified in connection with our Chief Executive Officer’s and Chief Financial Officer’s evaluation that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Summary of Significant Accounting Policies (Policies)

Jun. 30, 2015

Accounting Policies [Abstract]

Principles Of Consolidation

PRINCIPLESOF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

Business Combinations

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under FASB ASC 805, Business Combinations, (“FASB ASC 805”), for all transactions and events which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as measurement date for all assets and liabilities assumed. The Company also utilizes FASB ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

Use Of Estimates

USEOF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Revenue Recognition

REVENUE RECOGNITION

The Company relies upon FASB ASC 605, Revenue Recognition, to account for its revenue transactions. Revenue is recognized upon shipment provided that title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, have been successfully demonstrated. Out-of-pocket expenses that are reimbursable by the customer are included in revenue and cost of revenue.

Certain contracts with customers require the Company to perform tests of its products prior to shipment to ensure their performance complies with the Company’s published product specifications and, on occasion, with additional customer-requested specifications. In these cases, the Company conducts such tests and, if they are completed successfully, includes a written confirmation with each order shipped. As a result, at the time of each product shipment, the Company believes that no further customer testing requirements exist and that there is no uncertainty of acceptance by its customer.

The Company uses FASB Accounting Standards Update (“ASU”) No. 2009-13 (“FASB ASU 2009-13”), Multiple-Deliverable Revenue Arrangements. FASB ASU 2009-13 establishes a selling price hierarchy for determining the selling price of a deliverable, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third-party evidence (“TPE”) if VSOE is not available; and (3) best estimated selling price (“BESP”), if neither VSOE nor TPE is available. Additionally, FASB ASU 2009-13 expands the disclosure requirements related to a vendor’s multiple-deliverable revenue arrangements. 

The Company enters into multiple-deliverable arrangements that may include a combination of hardware components, related integration or other services. These arrangements generally do not include any performance-, cancellation-, termination- or refund-type provisions.

In accordance with the provisions of FASB ASU 2009-13, the Company allocates arrangement consideration to each deliverable in an arrangement based on its relative selling price. The Company generally expects that it will not be able to establish VSOE or TPE due to limited single element transactions and the nature of the markets in which the Company competes, and, as such, the Company typically determines its relative selling price using BESP.

The Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact if the product or service were sold by the Company on a standalone basis.

The Company’s determination of BESP involves the consideration of several factors based on the specific facts and circumstances of each arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, the Company’s ongoing pricing strategy and policies (as evident from the price list established and updated by management on a regular basis), the value of any enhancements that have been built into the deliverable and the characteristics of the varying markets in which the deliverable is sold.

The Company analyzes the selling prices used in its allocation of arrangement consideration at a minimum on an annual basis. Selling prices will be analyzed on a more frequent basis if a significant change in the Company’s business necessitates a more timely analysis or if the Company experiences significant variances in its selling prices.

Each deliverable within the Company’s multiple-deliverable revenue arrangements is accounted for as a separate unit of accounting under the guidance of FASB ASU 2009-13 if both of the following criteria are met: the delivered item or items have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The Company’s revenue arrangements generally do not include a general right of return relative to delivered products. The Company considers a deliverable to have standalone value if the item is sold separately by the Company or another vendor or if the item could be resold by the customer.

Deliverables not meeting the criteria for being a separate unit of accounting are combined with a deliverable that does meet that criterion. The appropriate allocation of arrangement consideration and recognition of revenue is then determined for the combined unit of accounting.

The Company also engages in long-term contracts for development, production and services activities which it accounts for consistent with FASB ASC 605-35, Accounting for Performance of Construction-Type and Certain Production-Type Contracts, and other relevant revenue recognition accounting literature. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. Generally for fixed-price contracts, other than service-type contracts, revenue is recognized primarily under the percentage of completion method or, for certain short-term contracts, by the completed contract method. Revenue from service-type fixed-price contracts is recognized ratably over the contract period or by other appropriate input or output methods to measure service provided, and contract costs are expensed as incurred. The Company establishes billing terms at the time project deliverables and milestones are agreed. Revenues recognized in excess of the amounts invoiced to clients are classified as unbilled receivables. The risk to the Company on a fixed-price contract is that if estimates to complete the contract change from one period to the next, profit levels will vary from period to period. For time and materials contracts, revenue reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well as reimbursement of other billable direct costs. For all types of contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable.

The Company also considers whether contracts should be combined or segmented in accordance with the applicable criteria under GAAP. The Company combines closely related contracts when all the applicable criteria under GAAP are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single project, which should be combined to reflect an overall profit rate. Similarly, the Company may separate a project, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria under GAAP are met. Judgment also is involved in determining whether a single contract or group of contracts may be segmented based on how the arrangement was negotiated and the performance criteria. The decision to combine a group of contracts or segment a contract could change the amount of revenue and gross profit recorded in a given period.

The use of contract accounting requires significant judgment relative to estimating total contract revenues and costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, anticipated increases in wages and prices for subcontractor services and materials, and the availability of subcontractor services and materials. The Company’s estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods.

Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. The Company records revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. Assumed recoveries for claims included in contracts in process were not material at June 30, 2015 or 2014.

The Company defines service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold. Examples of the Company's service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. The Company combines its product and service revenues into a single class as service revenues are less than 10 percent of total revenues.

The Company does not provide its customers with rights of product return, other than those related to warranty provisions that permit repair or replacement of defective goods. The Company accrues for anticipated warranty costs upon product shipment. Revenues from product royalties are recognized upon invoice by the Company. Additionally, all revenues are reported net of government assessed taxes (e.g. sales taxes or value-added taxes).

Cash And Cash Equivalents

CASHAND CASH EQUIVALENTS

Cash equivalents, consisting of highly liquid money market funds and U.S. government and U.S. government agency issues with original maturities of 90 days or less at the date of purchase, are carried at fair market value which approximates cost.

RESTRICTED CASH

The Company had restricted cash balances of $264 and $265 as of June 30, 2015 and 2014, respectively. The balances are classified as restricted cash on the accompanying consolidated balance sheet and are reflected in non-current assets. The balances at June 30, 2015 and 2014 included restrictions related to certain contracts with foreign customers that require a certificate of deposit to be held at a commercial bank until performance of the contracts have been completed.

Fair Value Measurement, Policy [Policy Text Block]

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, restricted cash and contingent consideration. FASB ASC 820, Fair Value Measurement and Disclosures, specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Concentration Of Credit Risk

CONCENTRATIONOF CREDIT RISK

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions that management believes are of high credit quality. At June 30, 2015 and 2014, the Company had $77,586 and $47,287, respectively, of cash and cash equivalents on deposit or invested with its financial and lending institutions.

The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. At June 30, 2015, five customers accounted for 55% of the Company's receivables, unbilled receivables and costs in excess of billings. At June 30, 2014, five customers accounted for 55% of the Company’s receivables, unbilled receivables and costs in excess of billings.

Inventory

INVENTORY

Inventory is stated at the lower of cost (first-in, first-out) or market value, and consists of materials, labor and overhead. On a quarterly basis, the Company evaluates inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand and non-cancelable on-order inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, product mix and possible alternative uses.

Goodwill And Acquired Intangible Assets

GOODWILLAND INTANGIBLE ASSETS

Goodwill is the amount by which the cost of the net assets obtained in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase. Goodwill is not amortized in accordance with the requirements of FASB ASC 350, Intangibles-Goodwill and Other (“FASB ASC 350”). Goodwill is assessed for impairment at least annually, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

Intangible assets result from the Company’s various business acquisitions (see Note H) and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, customer relationships, trademarks, backlog, and non-compete agreements. Intangible assets are reported at cost, net of accumulated amortization and are either amortized on a straight-line basis over their estimated useful lives of up to seven years or over the period the economic benefits of the intangible asset are consumed.

Long-Lived Assets

LONG-LIVED ASSETS

Long-lived assets primarily include property and equipment and acquired intangible assets. The Company regularly evaluates its long-lived assets for events and circumstances that indicate a potential impairment in accordance with FASB ASC 360, Property, Plant, and Equipment (“FASB ASC 360”). The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value.

Property And Equipment

Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and are not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Equipment under capital lease is recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method (see Note F).

As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

Expenditures for major software purchases and software developed for internal use are capitalized and depreciated using the straight-line method over the estimated useful lives of the related assets, which are generally three years. For software developed for internal use, all external direct costs for material and services and certain payroll and related fringe benefit costs are capitalized in accordance with FASB ASC 350. During fiscal 2015, 2014 and 2013, the Company capitalized $0, $362 and $91 of software development costs.

Deferred revenues consist of deferred product revenue, billings in excess of revenues, and deferred service revenue. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because one or more of the conditions for revenue recognition have not been met. Billings in excess of revenues represents milestone billing arrangements on percentage of completion projects where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty concessions, which are recognized ratably over the term of the arrangements. Customer advances represent deposits received from customers on an order.

Income Taxes

INCOME TAXES

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“FASB ASC 740”). The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse. The Company records a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

FASB ASC 740 requires a two-step approach to recognizing and measuring uncertain tax positions. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

Product Warranty Accrual

PRODUCT WARRANTY ACCRUAL

The Company’s product sales generally include a 12 month standard hardware warranty. At time of product shipment, the Company accrues for the estimated cost to repair or replace potentially defective products. Estimated warranty costs are based upon prior actual warranty costs for substantially similar transactions and any specifically identified warranty requirements. Product warranty accrual is included as part of accrued expenses in the accompanying consolidated balance sheets.

Research And Development Costs

RESEARCHAND DEVELOPMENT COSTS

Research and development costs are expensed as incurred. Research and development costs are primarily made up of labor charges and prototype material and development expenses.

Stock-Based Compensation

STOCK-BASED COMPENSATION

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. Stock-based compensation expense for the Company’s performance-based restricted stock awards are amortized over the requisite service period using graded vesting. The company’s other restricted stock awards recognize expense over the requisite service period on a straight-line basis. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options.

Retirement of Common Stock

RETIREMENT OF COMMON STOCK

Stock that is repurchased or received in connection with the exercise of stock options or in order to cover tax payment obligations triggered by exercise of stock options or the vesting of restricted stock is retired immediately upon the Company’s repurchase. The Company accounts for this under the cost method and upon retirement the excess amount over par value is charged against additional paid-in capital.

Net Earnings Per Share

NET EARNINGS PER SHARE

Basic net earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net earnings per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method.

Accumulated Other Comprehensive Income

ACCUMULATED OTHER COMPREHENSIVE INCOME

Accumulated other comprehensive income includes foreign currency translation adjustments and unrealized gains on investments. The components of accumulated other comprehensive income were $776 and $1,011 of accumulated foreign currency translation adjustments at June 30, 2015 and 2014. There were no material accumulated net unrealized gains on investments at June 30, 2015 and 2014.

Foreign Currency

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Europe and Japan. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in accumulated other comprehensive income in shareholders’ equity. Gains (losses) resulting from foreign currency transactions are included in other income (expense) and were immaterial for all periods presented.

Recently Issued Accounting Pronouncements

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on July 1, 2018 and can be early adopted for the fiscal year beginning July 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, an amendment of the FASB Accounting Standards Codification. The ASU has added additional disclosure requirements to the codification. It requires management to assess, at each interim and annual reporting period, whether substantial doubt exists about the Company’s ability to continue as a going concern. Substantial doubt exists if it is probable (the “probable” threshold under U.S. GAAP has generally been interpreted to be between 75 and 80 percent) that the Company will be unable to meet its obligations as they become due within one year after the date the financial statements are issued or available to be issued (assessment date). The ASU is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not expect a going concern uncertainty in the foreseeable future, and therefore this guidance is not expected to have a material impact to its consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-17, Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force), an amendment of the FASB Accounting Standards Codification. This ASU allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. As this guidance is applicable to separate financial statements of acquired entities, the Company does not expect this guidance to have a material impact to its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, an amendment of the FASB Accounting Standards Codification. This ASU eliminates the separate presentation of extraordinary items, net of tax and the related earnings per share, but does not affect the requirement to disclose material items that are unusual in nature or infrequently occurring. The ASU aligns U.S. GAAP more closely with IFRS (International Financial Reporting Standards). Entities will continue to evaluate whether items are unusual in nature or infrequent in their occurrence for disclosure purposes and when estimating the annual effective tax rate for interim reporting purposes. This ASU is effective for interim and annual periods in fiscal years beginning after December 15, 2015. The ASU allows prospective or retrospective applications. Early adoption is permitted if applied from the beginning of the fiscal year of adoption. The Company does not expect this guidance to have a material impact to its consolidated financial statements.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 1, 2014, the Company adopted FASB ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, an amendment of the FASB Accounting Standards Codification. The ASU requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist and certain criteria are met. Such adoption did not have a material impact to the Company's consolidated financial statements.

Effective October 1, 2014, the Company adopted FASB ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), an amendment of the FASB Accounting Standards Codification. The ASU clarifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity's operations and financial results. Additionally, the amendments in this ASU require expanded disclosure for discontinued operations to provide users with more information about the assets, liabilities, revenues, and expenses. Such adoption did not have a material impact to the Company's consolidated financial statements.

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

Discontinued Operations

During the fourth quarter of fiscal 2014, the Company conducted a strategic review of the Mercury Intelligence Systems (“MIS”) operating segment which encompassed an assessment of MIS' financial performance and contemporaneous future financial projections. The Company, with Board of Director's approval, concluded that a plan to divest the MIS operating segment would be in the best interests of the Company and its shareholders. On January 23, 2015, the Company completed the sale of MIS.

In fiscal 2014, the Company's MIS operating segment met the "held for sale" criteria in accordance with FASB ASC 205. As the Company did not anticipate continuing involvement in the operations of MIS after its divestiture, the MIS operating results had been reported as a discontinued operation for all periods presented.

The classification as "held for sale" was considered a triggering event for impairment testing under FASB ASC 350 and FASB ASC 360. However, since the Company conducted its annual goodwill impairment testing in its fourth quarter of fiscal 2014, which coincided with the plan to divest the MIS operating segment, the “held for sale” triggering event did not constitute a separate goodwill impairment test under FASB ASC 350 (see Note H). The triggering event, however, did require separate impairment testing of the MIS asset group’s long-lived assets under FASB ASC 360.

The goodwill impairment testing conducted in the fourth quarter of fiscal 2014 determined the MIS reporting unit's carrying value of goodwill exceeded its implied fair value, resulting in a $6,687 impairment charge. The impairment charge is reflected within discontinued operations of the Company's accompanying consolidated financial statements. The failure of the first step of the goodwill impairment test was driven by a decline in forecasted results of the MIS reporting unit. The fair value of the MIS reporting unit from the first step of the goodwill impairment test exceeded the fair value of the assets and liabilities of the MIS reporting unit, as determined by the second step of the goodwill impairment test. Testing of the valuation of long-lived assets of the MIS asset group indicated no impairment, as the estimated undiscounted cash flows of the MIS asset group, less estimated costs to sell, significantly exceeded its carrying value.

MIS was considered its own operating segment and was previously aggregated with MDS into one reportable segment based on similar economic and qualitative factors in accordance with FASB ASC 280. As MIS became a discontinued operation in the fourth quarter of fiscal 2014, the results of MIS had been excluded from the MDS reportable segment.  Accordingly, the revenues, costs of revenue, operating expenses, assets and liabilities of MIS have been reported separately as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) and Consolidated Balance Sheets for all periods presented. The discontinued operation's balances in the Consolidated Balance Sheets do not reflect intercompany receivable balances of MIS, and the results of discontinued operations do not reflect interest expense or the allocation of the Company's corporate general and administrative expenses.

During the second quarter of fiscal 2015, the Company determined that the MIS reporting unit's carrying value of goodwill exceeded its implied fair value, resulting in a further goodwill impairment charge of $2,283. This impairment charge is reflected within discontinued operations of the Company's accompanying fiscal 2015 consolidated financial statements.

On January 23, 2015, the Company completed the sale of MIS for approximately $1,600. The sale resulted in net proceeds of $885 and a loss on disposal of $892, which is reflected within discontinued operations of the Company's accompanying consolidated financial statements. The Company does not have continuing involvement in the operations of MIS after its divestiture.

The amounts reported in (loss) income from discontinued operations, net of income taxes were as follows:

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

PRINCIPLESOF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under FASB ASC 805, Business Combinations, (“FASB ASC 805”), for all transactions and events which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as measurement date for all assets and liabilities assumed. The Company also utilizes FASB ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

USEOF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

REVENUE RECOGNITION

The Company relies upon FASB ASC 605, Revenue Recognition, to account for its revenue transactions. Revenue is recognized upon shipment provided that title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, have been successfully demonstrated. Out-of-pocket expenses that are reimbursable by the customer are included in revenue and cost of revenue.

Certain contracts with customers require the Company to perform tests of its products prior to shipment to ensure their performance complies with the Company’s published product specifications and, on occasion, with additional customer-requested specifications. In these cases, the Company conducts such tests and, if they are completed successfully, includes a written confirmation with each order shipped. As a result, at the time of each product shipment, the Company believes that no further customer testing requirements exist and that there is no uncertainty of acceptance by its customer.

The Company uses FASB Accounting Standards Update (“ASU”) No. 2009-13 (“FASB ASU 2009-13”), Multiple-Deliverable Revenue Arrangements. FASB ASU 2009-13 establishes a selling price hierarchy for determining the selling price of a deliverable, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third-party evidence (“TPE”) if VSOE is not available; and (3) best estimated selling price (“BESP”), if neither VSOE nor TPE is available. Additionally, FASB ASU 2009-13 expands the disclosure requirements related to a vendor’s multiple-deliverable revenue arrangements. 

The Company enters into multiple-deliverable arrangements that may include a combination of hardware components, related integration or other services. These arrangements generally do not include any performance-, cancellation-, termination- or refund-type provisions.

In accordance with the provisions of FASB ASU 2009-13, the Company allocates arrangement consideration to each deliverable in an arrangement based on its relative selling price. The Company generally expects that it will not be able to establish VSOE or TPE due to limited single element transactions and the nature of the markets in which the Company competes, and, as such, the Company typically determines its relative selling price using BESP.

The Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact if the product or service were sold by the Company on a standalone basis.

The Company’s determination of BESP involves the consideration of several factors based on the specific facts and circumstances of each arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, the Company’s ongoing pricing strategy and policies (as evident from the price list established and updated by management on a regular basis), the value of any enhancements that have been built into the deliverable and the characteristics of the varying markets in which the deliverable is sold.

The Company analyzes the selling prices used in its allocation of arrangement consideration at a minimum on an annual basis. Selling prices will be analyzed on a more frequent basis if a significant change in the Company’s business necessitates a more timely analysis or if the Company experiences significant variances in its selling prices.

Each deliverable within the Company’s multiple-deliverable revenue arrangements is accounted for as a separate unit of accounting under the guidance of FASB ASU 2009-13 if both of the following criteria are met: the delivered item or items have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The Company’s revenue arrangements generally do not include a general right of return relative to delivered products. The Company considers a deliverable to have standalone value if the item is sold separately by the Company or another vendor or if the item could be resold by the customer.

Deliverables not meeting the criteria for being a separate unit of accounting are combined with a deliverable that does meet that criterion. The appropriate allocation of arrangement consideration and recognition of revenue is then determined for the combined unit of accounting.

The Company also engages in long-term contracts for development, production and services activities which it accounts for consistent with FASB ASC 605-35, Accounting for Performance of Construction-Type and Certain Production-Type Contracts, and other relevant revenue recognition accounting literature. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. Generally for fixed-price contracts, other than service-type contracts, revenue is recognized primarily under the percentage of completion method or, for certain short-term contracts, by the completed contract method. Revenue from service-type fixed-price contracts is recognized ratably over the contract period or by other appropriate input or output methods to measure service provided, and contract costs are expensed as incurred. The Company establishes billing terms at the time project deliverables and milestones are agreed. Revenues recognized in excess of the amounts invoiced to clients are classified as unbilled receivables. The risk to the Company on a fixed-price contract is that if estimates to complete the contract change from one period to the next, profit levels will vary from period to period. For time and materials contracts, revenue reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well as reimbursement of other billable direct costs. For all types of contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable.

The Company also considers whether contracts should be combined or segmented in accordance with the applicable criteria under GAAP. The Company combines closely related contracts when all the applicable criteria under GAAP are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single project, which should be combined to reflect an overall profit rate. Similarly, the Company may separate a project, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria under GAAP are met. Judgment also is involved in determining whether a single contract or group of contracts may be segmented based on how the arrangement was negotiated and the performance criteria. The decision to combine a group of contracts or segment a contract could change the amount of revenue and gross profit recorded in a given period.

The use of contract accounting requires significant judgment relative to estimating total contract revenues and costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, anticipated increases in wages and prices for subcontractor services and materials, and the availability of subcontractor services and materials. The Company’s estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods.

Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. The Company records revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. Assumed recoveries for claims included in contracts in process were not material at June 30, 2015 or 2014.

The Company defines service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold. Examples of the Company's service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. The Company combines its product and service revenues into a single class as service revenues are less than 10 percent of total revenues.

The Company does not provide its customers with rights of product return, other than those related to warranty provisions that permit repair or replacement of defective goods. The Company accrues for anticipated warranty costs upon product shipment. Revenues from product royalties are recognized upon invoice by the Company. Additionally, all revenues are reported net of government assessed taxes (e.g. sales taxes or value-added taxes).

CASHAND CASH EQUIVALENTS

Cash equivalents, consisting of highly liquid money market funds and U.S. government and U.S. government agency issues with original maturities of 90 days or less at the date of purchase, are carried at fair market value which approximates cost.

RESTRICTED CASH

The Company had restricted cash balances of $264 and $265 as of June 30, 2015 and 2014, respectively. The balances are classified as restricted cash on the accompanying consolidated balance sheet and are reflected in non-current assets. The balances at June 30, 2015 and 2014 included restrictions related to certain contracts with foreign customers that require a certificate of deposit to be held at a commercial bank until performance of the contracts have been completed.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, restricted cash and contingent consideration. FASB ASC 820, Fair Value Measurement and Disclosures, specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

CONCENTRATIONOF CREDIT RISK

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions that management believes are of high credit quality. At June 30, 2015 and 2014, the Company had $77,586 and $47,287, respectively, of cash and cash equivalents on deposit or invested with its financial and lending institutions.

The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. At June 30, 2015, five customers accounted for 55% of the Company's receivables, unbilled receivables and costs in excess of billings. At June 30, 2014, five customers accounted for 55% of the Company’s receivables, unbilled receivables and costs in excess of billings.

INVENTORY

Inventory is stated at the lower of cost (first-in, first-out) or market value, and consists of materials, labor and overhead. On a quarterly basis, the Company evaluates inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand and non-cancelable on-order inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, product mix and possible alternative uses.

GOODWILLAND INTANGIBLE ASSETS

Goodwill is the amount by which the cost of the net assets obtained in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase. Goodwill is not amortized in accordance with the requirements of FASB ASC 350, Intangibles-Goodwill and Other (“FASB ASC 350”). Goodwill is assessed for impairment at least annually, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

Intangible assets result from the Company’s various business acquisitions (see Note H) and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, customer relationships, trademarks, backlog, and non-compete agreements. Intangible assets are reported at cost, net of accumulated amortization and are either amortized on a straight-line basis over their estimated useful lives of up to seven years or over the period the economic benefits of the intangible asset are consumed.

LONG-LIVED ASSETS

Long-lived assets primarily include property and equipment and acquired intangible assets. The Company regularly evaluates its long-lived assets for events and circumstances that indicate a potential impairment in accordance with FASB ASC 360, Property, Plant, and Equipment (“FASB ASC 360”). The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value.

Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and are not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Equipment under capital lease is recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method (see Note F).

As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

Expenditures for major software purchases and software developed for internal use are capitalized and depreciated using the straight-line method over the estimated useful lives of the related assets, which are generally three years. For software developed for internal use, all external direct costs for material and services and certain payroll and related fringe benefit costs are capitalized in accordance with FASB ASC 350. During fiscal 2015, 2014 and 2013, the Company capitalized $0, $362 and $91 of software development costs.

DEFERRED REVENUESAND CUSTOMER ADVANCES

Deferred revenues consist of deferred product revenue, billings in excess of revenues, and deferred service revenue. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because one or more of the conditions for revenue recognition have not been met. Billings in excess of revenues represents milestone billing arrangements on percentage of completion projects where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty concessions, which are recognized ratably over the term of the arrangements. Customer advances represent deposits received from customers on an order.

INCOME TAXES

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“FASB ASC 740”). The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse. The Company records a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

FASB ASC 740 requires a two-step approach to recognizing and measuring uncertain tax positions. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

PRODUCT WARRANTY ACCRUAL

The Company’s product sales generally include a 12 month standard hardware warranty. At time of product shipment, the Company accrues for the estimated cost to repair or replace potentially defective products. Estimated warranty costs are based upon prior actual warranty costs for substantially similar transactions and any specifically identified warranty requirements. Product warranty accrual is included as part of accrued expenses in the accompanying consolidated balance sheets. The following table presents the changes in the Company's product warranty accrual.

	Fiscal 2015			Fiscal 2014			Fiscal 2013
Beginning balance at July 1,	$	2,078		$	2,522		$	1,360
Warranty assumed from Micronetics acquisition	—			—			245
Accruals for warranties issued during the period	1,465			1,951			4,592
Settlements made during the period	(1,569		)	(2,395		)	(3,675		)
Ending balance at June 30,	$	1,974		$	2,078		$	2,522

RESEARCHAND DEVELOPMENT COSTS

Research and development costs are expensed as incurred. Research and development costs are primarily made up of labor charges and prototype material and development expenses.

STOCK-BASED COMPENSATION

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. Stock-based compensation expense for the Company’s performance-based restricted stock awards are amortized over the requisite service period using graded vesting. The company’s other restricted stock awards recognize expense over the requisite service period on a straight-line basis. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options.

RETIREMENT OF COMMON STOCK

Stock that is repurchased or received in connection with the exercise of stock options or in order to cover tax payment obligations triggered by exercise of stock options or the vesting of restricted stock is retired immediately upon the Company’s repurchase. The Company accounts for this under the cost method and upon retirement the excess amount over par value is charged against additional paid-in capital.

NET EARNINGS PER SHARE

Basic net earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net earnings per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method. For all periods presented, income (loss) from continuing operations is the control number for determining whether securities are dilutive or not.

Basic and diluted weighted average shares outstanding were as follows:

	Years Ended June 30,
	2015	2014	2013
Basic weighted-average shares outstanding	32,114	31,000	30,128
Effect of dilutive equity instruments	825	—	—
Diluted weighted-average shares outstanding	32,939	31,000	30,128

Equity instruments to purchase 453, 3,526 and 4,077 shares of common stock were not included in the calculation of diluted net earnings per share for the fiscal years ended June 30, 2015, 2014 and 2013, respectively, because the equity instruments were anti-dilutive.

ACCUMULATED OTHER COMPREHENSIVE INCOME

Accumulated other comprehensive income includes foreign currency translation adjustments and unrealized gains on investments. The components of accumulated other comprehensive income were $776 and $1,011 of accumulated foreign currency translation adjustments at June 30, 2015 and 2014. There were no material accumulated net unrealized gains on investments at June 30, 2015 and 2014.

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Europe and Japan. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in accumulated other comprehensive income in shareholders’ equity. Gains (losses) resulting from foreign currency transactions are included in other income (expense) and were immaterial for all periods presented.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on July 1, 2018 and can be early adopted for the fiscal year beginning July 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, an amendment of the FASB Accounting Standards Codification. The ASU has added additional disclosure requirements to the codification. It requires management to assess, at each interim and annual reporting period, whether substantial doubt exists about the Company’s ability to continue as a going concern. Substantial doubt exists if it is probable (the “probable” threshold under U.S. GAAP has generally been interpreted to be between 75 and 80 percent) that the Company will be unable to meet its obligations as they become due within one year after the date the financial statements are issued or available to be issued (assessment date). The ASU is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not expect a going concern uncertainty in the foreseeable future, and therefore this guidance is not expected to have a material impact to its consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-17, Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force), an amendment of the FASB Accounting Standards Codification. This ASU allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. As this guidance is applicable to separate financial statements of acquired entities, the Company does not expect this guidance to have a material impact to its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, an amendment of the FASB Accounting Standards Codification. This ASU eliminates the separate presentation of extraordinary items, net of tax and the related earnings per share, but does not affect the requirement to disclose material items that are unusual in nature or infrequently occurring. The ASU aligns U.S. GAAP more closely with IFRS (International Financial Reporting Standards). Entities will continue to evaluate whether items are unusual in nature or infrequent in their occurrence for disclosure purposes and when estimating the annual effective tax rate for interim reporting purposes. This ASU is effective for interim and annual periods in fiscal years beginning after December 15, 2015. The ASU allows prospective or retrospective applications. Early adoption is permitted if applied from the beginning of the fiscal year of adoption. The Company does not expect this guidance to have a material impact to its consolidated financial statements.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 1, 2014, the Company adopted FASB ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, an amendment of the FASB Accounting Standards Codification. The ASU requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist and certain criteria are met. Such adoption did not have a material impact to the Company's consolidated financial statements.

Effective October 1, 2014, the Company adopted FASB ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), an amendment of the FASB Accounting Standards Codification. The ASU clarifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity's operations and financial results. Additionally, the amendments in this ASU require expanded disclosure for discontinued operations to provide users with more information about the assets, liabilities, revenues, and expenses. Such adoption did not have a material impact to the Company's consolidated financial statements.

Operating Segment, Geographic Information and Significant Customers

Segment Reporting [Abstract]

Operating Segment, Geographic Information and Significant Customers

Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. The Company utilizes the management approach for determining reportable segments in accordance with the authoritative guidance. The following operating segments were determined based upon the nature of the products offered to customers, the market characteristics of each operating segment and the Company's management structure:

• Mercury Commercial Electronics (“MCE”): this operating segment delivers more affordable, innovative, commercially developed, specialized processing subsystems powering today's critical defense and intelligence applications. MCE delivers secure solutions that are based upon open architectures and widely adopted industry standards. MCE delivers rapid time-to-value and service and support to prime defense contractors and commercial customers. MCE provides solutions to prime contractor customers on a variety of programs. MCE also provides technology building blocks to Mercury Defense Systems on key classified and unclassified programs. MCE has a legacy of embedded multi-computing and embedded sensor processing expertise. More recently, MCE has added substantial capabilities around radio frequency ("RF") and microwave technologies as well as emerging new manufacturing capabilities to bring design, production and test capabilities of its RF and microwave solutions to market on a more scalable basis.

• Mercury Defense Systems (“MDS”): this operating segment provides significant capabilities relating to pre-integrated, open, more affordable electronic warfare ("EW"), electronic attack ("EA") and electronic counter measure ("ECM") subsystems, and signals intelligence ("SIGINT") and electro-optical/infrared ("EO/IR") processing technologies and radar environmental test and simulation systems. MDS deploys these solutions on behalf of defense prime contractors and the Department of Defense ("DoD"), leveraging commercially available technologies and solutions (or “building blocks”) from the MCE business and other commercial suppliers. MDS leverages this technology to develop integrated sensor processing subsystems, often including classified application-specific software and intellectual property ("IP") for the C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ECM markets. MDS brings significant domain expertise to customers, drawing on over 25 years of experience in EW, SIGINT, and radar environment test and simulation.

The Company's operating segments were evaluated in accordance with FASB ASC 280 “Segment Reporting” in order to determine which operating segments qualified as reportable segments. The Company determined that both MCE and MDS met the quantitative thresholds for reporting.

The accounting policies of the reportable segments are the same as those described in “Note B: Summary of Significant Accounting Policies.” The profitability measure employed by the Company and its CODM as the basis for allocating resources to segments and assessing segment performance is adjusted EBITDA. The Company believes the adjusted EBITDA financial measure assists in providing an enhanced understanding of its underlying operational measures to manage its business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals.

Adjusted EBITDA is defined as income from continuing operations before interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting and stock-based compensation costs. Additionally, asset information by reportable segment is not reported because the Company and its CODM utilize consolidated asset information when making business decisions. The following is a summary of the performance of the Company's operations by reportable segment:

Description of Business

Description of Business

Mercury Systems, Inc. (the “Company” or “Mercury”) is a leading high-tech commercial provider of more affordable secure and sensor processing subsystems designed and made in the U.S.A. powering today's critical defense and intelligence applications. The Company delivers innovative solutions, rapid time-to-value and service and support to its defense prime contractor customers. The Company's products and solutions have been deployed in more than 300 programs with over 25 different defense prime contractors. Key programs include Aegis, Patriot, Surface Electronic Warfare Improvement Program ("SEWIP"), Gorgon Stare, Predator, F-35 and Reaper. The Company's organizational structure allows it to deliver capabilities that combine technology building blocks and deep domain expertise in the defense sector.

The Company's goal is to grow and build on its position as a critical component of the defense industrial base and become the leading provider of open and more affordable secure and sensor processing subsystems. The Mercury Commercial Electronics (“MCE”) operating segment designs, develops and builds open sensor processing products and subsystems that include embedded processing modules and subsystems, radio frequency (“RF”) and microwave multi-function assemblies as well as subsystems, and RF and microwave components. The Mercury Defense Systems (“MDS”) operating segment provides significant capabilities relating to pre-integrated, open, more affordable electronic warfare ("EW"), electronic attack ("EA") and electronic counter measure ("ECM") subsystems and significant capabilities in signals intelligence ("SIGINT"), and electro-optical/infrared ("EO/IR") processing technologies and radar environment test and simulation systems.

In June 2014, the Company initiated a plan to divest the Mercury Intelligence Systems (“MIS”) operating segment, based on the Company's strategic direction and investment priorities focusing on its core business. As a result, the Company's MIS operating segment met the “held for sale” criteria in accordance with Financial Accounting Standard Boards (“FASB”) Accounting Standards Codification (“ASC”) 205, Presentation of Financial Statements, (“FASB ASC 205”) as of June 30, 2014 (see Note C to consolidated financial statements). The consolidated financial statements, excluding the statements of shareholders' equity and cash flows, and the notes to the consolidated financial statements were restated for all periods presented to reflect the discontinuation of the MIS operating segment, in accordance with FASB ASC 205. On January 23, 2015, the Company completed the sale of the MIS operating segment.

Commitments and Contingencies

Commitments and Contingencies

LEGAL CLAIMS

The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of our business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company's cash flows, results of operations, or financial position.

INDEMNIFICATION OBLIGATIONS

The Company's standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company's products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited.

In connection with the sale of the Company’s former MIS business, the Company provided indemnification to the buyer of the business. The Company’s indemnification obligations generally cover the buyer for damages resulting from breaches of representations, warranties and covenants contained in the purchase and sale agreement and generally cover pre-closing tax liabilities of the business. The Company’s indemnification obligations regarding the MIS business are generally subject to caps.

PURCHASE COMMITMENTS

As of June 30, 2015, the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $27,376.

LEASE COMMITMENTS

The Company leases certain facilities, machinery and equipment under various cancelable and non-cancelable operating leases that expire at various dates through fiscal 2025. The leases contain various renewal options. Rental charges are subject to escalation for increases in certain operating costs of the lessor. For tenant improvement allowances and rent holidays, the Company records a deferred rent liability on the consolidated balance sheets and amortizes the deferred rent over the terms of the leases as reductions to rent expense on the consolidated statements of operations. Rental expense during the fiscal years ended June 30, 2015, 2014, and 2013 was $3,777, $4,213 and $4,167, respectively. Minimum lease payments under the Company’s non-cancelable operating leases are as follows:

SENIOR UNSECURED CREDIT FACILITY

On October 12, 2012, the Company entered into a credit agreement (the “Credit Agreement”) with a syndicate of commercial banks, with KeyBank National Association acting as the administrative agent. The Credit Agreement provides for a $200,000 senior unsecured revolving line of credit (the “Revolver”). The Company can borrow up to $200,000 based on its consolidated EBITDA for the prior trailing four quarters and subject to compliance with the financial covenants discussed below. The Revolver is available for working capital, acquisitions, and general corporate purposes of the Company and its subsidiaries. The Revolver is available for borrowing during a five year period, with interest payable periodically during such period as provided in the Credit Agreement and principal due at the maturity of the Revolver.

The Credit Agreement has an accordion feature permitting the Company to request from the lenders an increase in the aggregate amount of the credit facility in the form of an incremental revolver or term loan in an amount not to exceed $50,000. Any such increase would require only the consent of the lenders increasing their respective commitments under the credit facility.

The interest rates applicable to borrowings under the Credit Agreement involve various rate options that are available to the Company. The rates are calculated using a combination of conventional base rate measures plus a margin over those rates. The base rates consist of LIBOR rates or prime rates. The actual rates will depend on the level of these underlying rates plus a margin based on the Company's leverage at the time of borrowing.

Borrowings under the Credit Agreement are senior unsecured loans. Each of the Company's domestic subsidiaries is a guarantor under the Credit Agreement.

The Credit Agreement provides for conventional affirmative and negative covenants, including a maximum leverage ratio of 3.50x and a minimum interest coverage ratio of 3.0x. Each of the two ratios referred to above is calculated based on consolidated EBITDA, as defined in the Credit Agreement, for each consecutive four fiscal quarter period, after giving pro forma effect for any acquisitions. Acquisitions are permitted under the Credit Agreement without any dollar limitation so long as, among other requirements, no default or event of default exists or would result. In addition, the Credit Agreement contains certain customary representations and warranties, and events of default.

As of June 30, 2015, there was $151,549 of borrowing capacity available based on our consolidated EBITDA for the trailing four quarters ended June 30, 2015. There were no borrowings outstanding on the Credit Agreement; however, there were outstanding letters of credit of $3,839. As of June 30, 2015, the Company is in compliance with the covenants in the Credit Agreement.

In fiscal 2015 and 2014, the Company retired $733 and $715, respectively, of fully depreciated computer equipment and software assets that were no longer in use by the Company. 

Depreciation expense related to property and equipment for the fiscal years ended June 30, 2015, 2014 and 2013 was $6,332, $7,625 and $8,445, respectively.

On June 27, 2013, the Company entered into a sales agreement and a separate short-term lease agreement in connection with the Company’s legacy Hudson, New Hampshire, facility. Pursuant to the sale agreement, the Company sold all land, land improvements, buildings and building improvements related to the facility. The loss on the sale of the facility was approximately $1,091 and is recorded in restructuring and other charges in the accompanying consolidated statement of operations.

On April 20, 2007, the Company entered into a sales agreement and a lease agreement in connection with a sale-leaseback of the Company’s headquarters in Chelmsford, Massachusetts. Pursuant to the agreements, the Company sold all land, land improvements, buildings and building improvements related to the facilities and leased back those assets. The term of the lease is ten years and includes twofive year options to renew. Under the provisions of sale-leaseback accounting, the transaction was considered a normal leaseback; thus the realized gain of $11,569 was deferred and will be amortized to other income on a straight-line basis over the initial lease term.

The unamortized deferred gain consisted of the following of which the current portion is included in accrued expenses and the non-current portion is separately classified in the accompanying consolidated balance sheets:

Restructuring and Related Activities [Abstract]

Restructuring Plan

Restructuring

During fiscal 2015, the Company incurred restructuring and other charges of $3,175, which affected both MCE and MDS reportable segments as the Company completed its acquisition integration plan. Additionally, during the fourth quarter of fiscal 2015, the Company eliminated 16 positions, primarily in operations, in the MCE reportable segment.

During fiscal 2014, the Company announced a restructuring plan ("2014 Plan") that was implemented as part of the final phase of integration activities relating to the Company’s recent acquisitions. The acquisition integration plan included the consolidation of manufacturing facilities, centralization of administrative functions using common information systems and processes, and realignment of research and development resources. The acquisition integration plan included the elimination of 70 positions largely in engineering, manufacturing and administrative functions. Additionally, the Company closed four facilities relocating all related activities to the Company's Advanced Microelectronics Center ("AMC") in Hudson, New Hampshire. The Company also completed the first phase of the Chelmsford, Massachusetts headquarters consolidation in the fourth quarter of fiscal 2014. These restructuring and other charges associated with the Company's fiscal 2014 restructuring plan amounted to $5,443 and affected both MCE and MDS reportable segments. In the event that the Company is unable to sublease the unoccupied portion of its headquarters complex in Chelmsford, Massachusetts, it will incur nominal, periodic restructuring charges through fiscal 2017 in its MCE reportable segment.

All of the restructuring and other charges are classified as operating expenses in the consolidated statements of operations and any remaining severance obligations are expected to be paid within the next twelve months. The remaining restructuring liability is classified as accrued expenses in the consolidated balance sheets.

The following table presents the detail of expenses by reportable segment for the Company’s restructuring plans:

	Severance & Related			Facilities & Other			Total

Balance at June 30, 2013	$	133,783	$	33,768	$	167,551
Goodwill adjustments during fiscal 2014	595		—		595
Balance at June 30, 2014 and 2015	$	134,378	$	33,768	$	168,146

In accordance with FASB ASC 350 Intangibles-Goodwill and Other “FASB ASC 350”, the Company determines its reporting units based upon whether discrete financial information is available, if management regularly reviews the operating results of the component, the nature of the products offered to customers and the market characteristics of each reporting unit. A reporting unit is considered to be an operating segment or one level below an operating segment also known as a component. MCE has four components with discrete financial information available which are reviewed by their segment manager; however, those four components are economically similar in nature and thus have been aggregated into a single reporting unit at the operating segment level. MDS is a sole component and the reporting unit is at the operating segment level. The Company determined that its reporting units are the same as its operating segments, MCE and MDS.

As defined by FASB ASC 350, goodwill is tested for impairment on an interim basis at the occurrence of certain triggering events or at a minimum on an annual basis. In fiscal 2015, there were no triggering events from continuing operations which required an interim goodwill impairment test.

The Company follows FASB ASC 350 in assessing whether the fair value of a reporting unit is less than its carrying amount. As of June 30, 2015, both MCE and MDS had goodwill balances and the annual impairment analysis was performed for each reporting unit in the fourth quarter of fiscal 2015. The results of the Company's step one interim goodwill impairment test indicated that the fair values of the MCE and MDS reporting units were substantially in excess of their carrying values. As such, step two of the goodwill impairment testing was not required. Consistent with prior years, the valuation was based upon a discounted cash flow analysis and corroborated by a market-based analysis which compares the trading multiples of public companies in similar lines of business.

At June 30, 2015, the Company evaluated the need for a valuation allowance on deferred tax assets. In assessing whether the deferred tax assets are realizable, management considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the Company's past operating results, its forecast of future earnings, future taxable income, and tax planning strategies. The Company continues to conclude that it is more likely than not that most domestic deferred tax assets would be realizable based on the financial performance in fiscal year 2015, projected future taxable income and the reversal of existing deferred tax liabilities.

The Company continues to record a full valuation allowance on certain state research and development (“R&D”) and investment tax credits, and capital loss carryforwards as of June 30, 2015 as management continues to believe that it is not more likely than not that these deferred tax assets would be realized. Any future reversals of the valuation allowance will impact income tax expense.

The Company had federal research and development credit carryforwards of $959, which will expire from 2032 through 2033. The Company had state research and development credit carryforwards of $14,899, which will expire from 2016 through 2029. The Company also had state investment tax credits carryforwards of $404.

Upon consideration of changing business conditions and cash position in its foreign subsidiaries, management has determined that it does not need to indefinitely reinvest the earnings of certain foreign subsidiaries. Therefore, the Company has accrued deferred taxes in association with $672 in undistributed earnings and profits.

The Company files income tax returns in all jurisdictions in which it operates. The Company has established reserves to provide for additional income taxes that management believes will more likely than not be due in future years as these previously filed tax returns are audited. These reserves have been established based upon management’s assessment as to the potential exposures. All tax reserves are analyzed quarterly and adjustments are made as events occur and warrant modification.

The changes in the Company’s reserves for unrecognized income tax benefits are summarized as follows:

	Year Ended June 30,
	2015			2014
Unrecognized tax benefits, beginning of period	$	3,142		$	2,923
Increases for previously recognized positions	123			102
Reductions as a result of a lapse of the applicable statue of limitations	(1,197		)	(166		)
Increases for currently recognized positions	122			283
Unrecognized tax benefits, end of period	$	2,190		$	3,142

The $2,190 of unrecognized tax benefits as of June 30, 2015, if released, would reduce income tax expense.

The Company’s major tax jurisdiction is the U.S. and the open tax years are fiscal 2011 through 2015.

The Company is currently under audit by the Internal Revenue Service for fiscal year 2013. There have been no significant changes to the status of this examination during the year ended June 30, 2015. It is reasonably possible that within the next 12 months the Company’s unrecognized tax benefits, exclusive of interest, may decrease by up to $757 at the conclusion of the audit. We expect that the decrease, if recognized, would not affect the effective tax rate.

STOCK OPTION PLANS

The number of shares authorized for issuance under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”), is 11,424 shares at June 30, 2015. On October 21, 2014, the Company's number of shares authorized for issuance under the 2005 Plan increased by 3,406 shares, including 3,200 shares approved by the Company's shareholders at the 2014 Annual Meeting of Shareholders and 206 shares as a result of forfeitures, cancellations and/or terminations from the Company's 1997 Stock Option Plan (the "1997 Plan"). The 2005 Plan will be increased by any future cancellations, forfeitures or terminations (other than by exercise) under the 1997 Plan. The 2005 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. All stock options are granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant and the options generally have a term of seven years. There were 3,648 shares available for future grant under the 2005 Plan at June 30, 2015.

The number of shares authorized for issuance under the 1997 Plan was 8,650 shares, of which 100 shares could be issued pursuant to restricted stock grants. The 1997 Plan provided for the grant of non-qualified and incentive stock options and restricted stock to employees and non-employees. All stock options were granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant. The options typically vest over periods of zero to four years and have a maximum term of 10 years. Following shareholder approval of the 2005 Plan on November 14, 2005, the Company’s Board of Directors determined that no further grants of stock options or other awards would be made under the 1997 Plan, and the 1997 Plan subsequently expired in June 2007. The foregoing does not affect any outstanding awards under the 1997 Plan, which remain in full force and effect in accordance with their terms.

On August 15, 2014, as part of the Company's ongoing annual equity grant program for employees, the Company granted performance-based restricted stock awards to certain executives pursuant to the 2005 Plan. These performance awards vest annually over a three year requisite service period subject to the achievement of specific financial performance targets related to adjusted EBITDA as a percentage of revenue. Based on the performance targets, these awards require graded vesting that results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic compensation expense accordingly.

EMPLOYEE STOCK PURCHASE PLAN

The number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 1,400 shares. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. The number of shares issued under the ESPP during fiscal years 2015, 2014, and 2013 was 79, 92 and 104, respectively. Shares available for future purchase under the ESPP totaled 85 at June 30, 2015.

STOCK-BASED COMPENSATION EXPENSEAND ASSUMPTIONS

The Company recognized the full expense of its share-based payment plans in the consolidated statements of operations for the fiscal years 2015, 2014, and 2013 in accordance with FASB ASC 718 and did not capitalize any such costs on the consolidated balance sheets, as such costs that qualified for capitalization were not material. Under the fair value recognition provisions of FASB ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period. The following table presents share-based compensation expenses from continuing operations included in the Company’s consolidated statement of operations:

	Year Ended June 30,
	2015			2014			2013
Cost of revenues	$	493		$	601		$	371
Selling, general and administrative	6,751			7,024			6,436
Research and development	1,396			1,374			1,047
Share-based compensation expense before tax	8,640			8,999			7,854
Income taxes	(3,332		)	(3,420		)	(2,877		)
Share-based compensation expense, net of income taxes	$	5,308		$	5,579		$	4,977

There were no options granted during fiscal years 2015 or 2014. The only stock options granted during fiscal year 2013 were related to the Micronetics stock option rollover at the acquisition date. The following table sets forth the weighted-average key assumptions and fair value results for stock options granted during fiscal years 2015, 2014 and 2013:

	Years Ended June 30,
	2015			2014			2013
Weighted-average fair value of options granted	$	—		$	—		$	3.80
Option life(1)	—			—			4.5
Risk-free interest rate(2)	—		%	—		%	0.73		%
Stock volatility(3)	—		%	—		%	58		%
Dividend rate	—		%	—		%	—		%

(1) The option life was determined based upon historical option activity.

(2) The risk-free interest rate for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

(3) The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Company’s common stock over the most recent period equal to the expected option life of the grant, the historical short-term trend of the option and other factors, such as expected changes in volatility arising from planned changes in the Company’s business operations.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at June 30, 2015:

	Fair Value Measurements
	June 30, 2015		Level 1		Level 2		Level 3
Assets:
Operating cash	$	47,586	$	47,586	$	—	$	—

Cost-method investment	500		—		—		500
Total	$	78,350	$	47,850	$	30,000	$	500

The carrying values of cash and cash equivalents, including U.S. Treasury bills and money market funds, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities. The value of the certificates of deposit is based on the quoted price for identical or similar instruments in markets that are not active or are directly or indirectly observable. The cost-method investment does not have a readily determinable fair value, as such the Company recorded the investment as a long term asset at cost and will continue to evaluate the asset for impairment.

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at June 30, 2014:
