Applied Technology designs, manufactures, sells, and services innovative precision agriculture products and information management tools that help growers reduce costs, more precisely control inputs, and improve farm yields.  The Applied Technology product families include field computers, application controls, GPS-guidance and assisted-steeringsteering systems, automatic boom controls, injection systems, yield monitoring controls, and planter and seeder controls. Applied Technology's services include high-speed in-field Internet connectivity and cloud-based data management. The Company's investment in Site-Specific Technology Development Group, Inc. (SST), a software company, and the continued build-out of the Slingshot™ platform havehas also

positioned Applied Technology as an information platform that improves grower decision-making and achieves business efficiencies for its agriculture retail partners.

Applied Technology sells its precision agriculture control products to both original equipment manufacturers (OEMs) and through aftermarket distribution partners in the United States and in most major agricultural areas around the world. The Company's

Engineered Films produces high-performance plastic films and sheeting for geomembrane, (which includes energy), agricultural, construction, and industrial applications. Engineered Films acquired the assets of Colorado Lining International, Inc. (CLI) in September 2017. This acquisition enhanced the division's geomembrane market position through extended service and product offerings with the addition of new design-build and installation service components. The acquisition of CLI advanced Engineered Films’ business model into a vertically-integrated, full-service solutions provider for the geomembrane market.

Engineered Films sells plastic sheeting both direct to end-customers and through independent third-party distributors. The majority of product sold into the construction and agriculture markets is through distributors, while sales into the geomembrane and industrial markets are more direct in nature. The Company extrudes a significant portion of the film converted for its commercial products and believes it is one of the largest sheeting converters in the United States in the markets it serves. Engineered Films' ability to both extrude and convert films, along with offering installation services for its geomembrane products, allows it to provide a more customized solution to customers. A number of film manufacturers compete with the Company on both price and product availability. Engineered Films is the Company's most capital-intensive business segment, and historically has made sizable investments in new extrusion capacity and conversion equipment. This segment's capital expenditures were $8.1 million in fiscal 2018, $2.8 million in fiscal 2017, and $10.8 million in fiscal 2016, and $8.2 million in fiscal 2015.2016.

Aerostar serves the aerospace/defense, radar and situational awarenesslighter-than-air markets. Aerostar's primary products include high-altitude (stratospheric or lighter-than-air) balloons, tethered aerostats, and radar processing systems. These products can be integrated with additional third-party sensors to provide research, communications, and situational awareness capabilities to governmental and commercial customers. Aerostar’s growth strategy emphasizes the design and manufacture of proprietary products in these markets. Aerostar also pursues product and support services contracts with agencies and instrumentalities of the U.S. government as well as sales of advanced radar systems and aerostats in international markets. In previous years, Aerostar also provided contract manufacturing services. The Company largely exited this business and the planned reduction of contract manufacturing activities was completed in fiscal 2016.

Aerostar sells to government agencies as both a prime contractor and subcontractor, and to commercial users primarily as a sub-contractor. Certain projects Aerostar bids on can be larger-scale, with opportunities for $10 million projects. Further, Direct Commercial Salessales to foreign governmentsgovernment agencies often involve large contracts subject to frequent delays because of budget uncertainties, regional military conflicts, and protracted negotiation processes. The timing and size of contract wins can create volatility in Aerostar’s results.

As we beginThe Company is very pleased with the performance achieved by all three operating divisions throughout fiscal year 2018,2018. All three divisions achieved double-digit sales growth and the Company continues to face uncertainties in end-market demand, but we have created opportunities for growth with the investments we have made over the last few years. Momentum continued to build throughout fiscal year 2017 and continues today. Despite the macro challenges faced in certain end markets, managementbelieves it is relatively optimisticwell positioned for the year ahead.

ForIn fiscal 2018 Applied Technology end-market demandachieved strong results in the face of challenging agricultural market conditions. The Company expects to continue to drive growth and will continue to strategically fund several long-term investments. Subsequent to the end of the fourth quarter, the division launched a strategic initiative to grow its local presence in Brazil and drive organic growth in Latin America, in order to better capitalize on one of the largest agricultural markets in the world.

Engineered Films demonstrated impressive operational discipline and sustained high plant utilization throughout fiscal 2018. The division grew sales by approximately $75 million year-over-year, and prior investments in acquisitions and manufacturing capacity drove strong growth in every market served. The division continues to be subduedsee opportunities for growth and management does not expect an improvementis investing in such demand to occur during fiscal year 2018. With that said, the research and development efforts that were maintained during the market downturn have led to new product introductions which are seeing success. As a result, the division has been able to increase its market share position and overcome the down market to achieve growth both domestically and internationally. Management expects this to continueadditional capacity in fiscal year 2018.

During the year, Aerostar improved its financial performance and achieved more consistency and stability in its results. The division continues to sharpen its focus on the stratospheric balloon platform, and has divested of a revenue declinefew non-strategic portions of approximately 66% in fiscal year 2016,its business during and subsequent to the division began to see conditions improve in the second halfend of fiscal year 2017. Although there remains uncertainty2018. Strong performance on existing programs is driving confidence for continued growth with respect to geomembrane end-market demand in the future, management expects growth in this market in fiscal year 2018. In addition, management expects sales into the industrial market to improve in fiscal 2018 as the result of success in selling the capacity of its new industrial production line that was put in service in first quarter fiscal 2017. Overall, sales growth in the division is expected in fiscal year 2018.

profitabilityOverall, the Company is well positioned as it enters fiscal 2019 because of the division. Overall, management's outlook foractions taken and investments made to preserve and strengthen our core business. Furthermore, the divisionCompany is evaluating strategic acquisitions and will continue to invest in additional manufacturing capacity and technology development to enhance its core product lines. The Company's goal remains cautious, but we do expect financial performance to improve in fiscal 2018.

No customers accounted for 10% or more of consolidated sales in fiscal years 2018, 2017, andor 2016. Sales to Brawler Industrial Fabrics, a customer in the Engineered Films Division, accounted for 14% of consolidated sales in fiscal 2015.

Some seasonal demand exists in both the Applied Technology and Engineered Films divisions, primarily due to their respective exposure to the agricultural market. Although net working capital (accounts receivable, net plus inventories less accounts payable) requirements tend to be the highest in the fiscal first quarter,However, given the overall diversification of the Company, the seasonal fluctuations in net working capital (accounts receivable, net plus inventories less accounts payable) are not usually significant.

 

The principal financial instruments that the Company maintains are cash, cash equivalents, short-term investments, accounts receivable, accounts payable, accrued liabilities, and acquisition-related contingent payments. The Company manages the interest rate, credit, and market risks associated with these accounts through periodic reviews of the carrying value of assets and liabilities and establishment of appropriate allowances in accordance with Company policies. The Company does not use off-balance sheet financing, except to enter into operating leases.

The Company obtains a wide variety of materials from numerous vendors. Principal materials include electronic components for Applied Technology and Aerostar, various polymeric resins for Engineered Films, and fabrics and film for Aerostar. Engineered Films has experienced volatile resin prices over the past three years. Price increases could not always be passed on to customers due to weak demand and/or a competitive pricing environment. Predicting future material volatility and the related potential impact on the Company is not easily estimated and the Company is unable to do so to the degree required to build reliance on such forecasts.

The Company owns a number of patents. The Company does not believe that its business, as a whole, is materially dependent on any one patent or related group of patents. The Company focuses significant research and development effort to develop technology-based offerings. As such, the protection of the Company’s intellectual property is an important strategic objective. Along with an aggressive posture toward patenting new technology and protecting trade secrets, the Company has restrictions on the disclosure of our technology to industry and business partners to ensure that our intellectual property is maintained and protected.

The three business segments conduct ongoing research and development (R&D) efforts to improve their product offerings and develop new products. Most of the Company's R&D expenditures are directed toward new product development. R&D investment is particularly strong within the Applied Technology Division. Development of new technology and product enhancements within Applied Technology is a competitive differentiator and central to its long-term strategy. Engineered Films also utilizes R&D spending to develop new products and to value engineer and reformulate its products. These R&D investments deliver high-value film solutions to the markets it serves and also result in lower raw material costs and improved quality for existing product lines. Aerostar's investment in the development of new technology has a particular emphasis on its core stratospheric balloon product platform. The Company's total R&D costs are presented in the Consolidated Statements of Income and Comprehensive Income.

The Company believes that, in all material respects, it is in compliance with applicable federal, state and local environmental laws and regulations. Expenditures incurred in the past relating to compliance for operating facilities have not significantly affected the Company's capital expenditures, earnings, or competitive position.

As of February 1, 2017,2018, the Company's order backlog totaled approximately $25.7$40.3 million. Backlog amounts as of February 1, 2017 and 2016 and 2015 were $18.6$25.7 million and $26.7$18.6 million, respectively. Because the length of time between order and shipment varies considerably by business segment and customers can change delivery schedules or potentially cancel orders, the Company does not believe that backlog, as of any particular date, is necessarily indicative of actual net sales for any future period.

As of January 31, 2017,2018, the Company had 941employees1,157 employees (including temporary workers). Following is a summary of active employees by segment: Applied Technology - 382;394; Engineered Films - 315;471; Aerostar - 163;195; and Corporate Services - 81.97. Management believes its relationship with its employees is good.

The Company's business is subject to many risks. Set forthrisks, which by their nature are unpredictable or unquantifiable and may be unknown. In an attempt to provide you with information on potential risks the Company may encounter, we have provided below, what we believe are the most importantsignificant risks we face. In evaluating our business and your investment in the Company youcould potentially face, based on our knowledge, experience, information and assumptions. The risks provided below should also considerbe assessed contemporaneously with other information contained in this Form 10-K, including Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the risks and uncertainties addressed under "Forward-Looking Statements" on page 35, the Notes to the Consolidated Financial Statements on page 45, and other information presented in or incorporated by reference into this Annual Report on Form 10-K. The risks contained herein, as well as other statements in this 10-K are forward-looking statements and, as such, are uncertain. Such statements are

not guarantees of future performance and undue reliance should not be placed on them. The indeterminate nature of risk factors makes them subject to change, and certain risks and uncertainties could potentially cause material changes to actual results. Some of these risks may affect the entire Company, where others may only affect particular segments of our business, or may have identifiedno material weaknesses in our internal control over financial reporting which could, if not remediated, result in material misstatements in our consolidated financial statements. We may be unableaffect at all.

The Company, except as required by law, disclaims any obligation to develop, implement, and maintain appropriate controls in future periods which could adversely affect our ability to report our financial condition and resultsupdate or revise the risk factors contained herein, regardless of operations in a timely and accurate manner, which may adversely affect investor confidence in our company and,changes, whether as a result the value of our common stock.

The Company's Applied Technology Division is largely dependent on the ability of farmers, agricultural service providers, and custom operatorsapplicators to purchase agricultural equipment, including its products. If such farmers, agricultural service providers, or custom applicators experience weather conditions or natural disasters resulting in unfavorable crop prices or farm incomes, sales in the Applied Technology Division may be adversely affected.

Weather conditions and natural disasters can also adversely affect sales in the Company's Engineered Films Division. To the extent weather conditions or natural disasters curtail construction or agricultural activity, such as a late spring or drought, sales of the segment'sdivision's plastic sheeting would likely decrease.

Seasonal weather-related and market demandweather-related variation could also affect quarterly results. If expected sales are deferred in a fiscal quarter while inventory has been built and operating expenses incurred, financial results could be negatively impacted.

The Company’s primary manufacturing facilities for each of its operating divisions are located on contiguous properties in Sioux Falls, South Dakota. If weather-related natural disasters such as tornadoes or flooding were to occur in the area, such conditions could impede the manufacturing and shipping of products and potentially adversely affect the Company’s sales, transactions processing, and financial reporting. The Company has disaster recovery plans in place to mitigatemanage the Company’s risks to these vulnerabilities but these measures may not be adequate, implemented properly, or executed timely to ensure that the Company’s operations are not disrupted. Such consequences could adversely affect our results of operations, financial condition, liquidity, and cash flows.

The Company's Engineered Films Division utilizes significant amounts of polymeric resin, the cost of which depends upon market prices for natural gas and oil and other market forces. These prices are subject to worldwide supply and demand as well as other factors beyond the control of the Company.our control. Although the Engineered Films Division is sometimes able to pass on such price increases to its customers, significant variations in the cost of polymeric resins can affect the Company's operating results from period to period. Unusual supply disruptions, such as one caused by a natural disaster, could cause suppliers to invoke "force majeure" clauses in their supply agreements, causing shortages of material. Success in offsetting higher raw material costs with price increases is largely influenced by competitive and economic conditions and could vary significantly depending on the market served. Unusual supply disruptions, such as one caused by a natural disaster, could cause suppliers to invoke "force majeure" clauses in their supply agreements, causing shortages in supply of material. If the Company is not able to fully offset the effects of adverse materials availability and correspondinglyor higher costs, financial results could be adversely affected, which in turn could adversely affect our results of operations, financial condition, liquidity, and cash flows.

Electronic components used by both the Applied Technology Division and Aerostar Division are sometimes in short supply, andwhich may impact our ability to meet customer demand.

Agricultural income levels are affected by agricultural commodity prices and input costs. As a result, changes in commodity prices or input costs that reduce agricultural income levels could have a negative effect on the ability of growers and their service providers to purchase the Company's precision agriculture products manufactured by its Applied Technology Division.

Exploration for oil and natural gas fluctuates with their price and energy market conditions are subject to volatility. Certain plastic sheeting manufactured and sold by our Engineered Films Division is sold as pit and pond liners to contain water used in the drilling processes for these energy commodities. Lower prices for oil and natural gas could reduce exploration activities and demand for our products.

Film manufacturing uses polymeric resins, which can be subject to changes in price as the cost of oil or natural gas changes. Accordingly, volatility in oil and natural gas prices may negatively affect our raw material costs and cost of goods sold and potentially cause us to increase prices, which could adversely affect our sales and/or profitability.

The Company's operating results in Applied Technology, Engineered Films, and Aerostar depend upon the ability to renew the pipeline of new productstechnologies and servicesproducts and to bring these to market. This ability could be adversely affected by difficulties or delays in product development, such as the inability to identify viable new products, successfully complete research and development projects, obtain relevant regulatory approvals, obtain intellectual property protection, or gain market acceptance of new products and services. Because of the lengthy development process, technological challenges, and competition, there can be no assurance that any of the products the Company is currently developing, or could begin to develop in the future, will achieve commercial success. Technical advancements in products may also increase the risk of product failure, increasing product returns or warranty claims and settlements. In addition, sales of the Company's new products could replace sales of some of its current products, offsetting the benefit of even a successful new product introduction.

The Company’s growth strategy relies on the design and manufacture of proprietary products. Highly technical, specialized product inventories may be more susceptible to fluctuations in market demand. If demand is unexpectedly low, write-downs or impairments of such inventory may become necessary. Either of these outcomes could adversely affect our results of operations. Start-up costs and inefficiencies can adversely affect operating results and such costs may not be recoverable in a proprietary product environment because the Company may not receive reimbursement from its customers for such costs.

Competition in agriculture markets could come from our current customers if original equipment manufacturers develop and integrate precision agriculture technology products themselves rather than purchasing from third parties, thereby reducing demand for Applied Technology’s products.

Regulatory restrictions could be placed on hydraulic fracturing activities because of environmental and health concerns, reducing demand for Engineered Film’s products. For Engineered Films, the development of alternative technologies, such as closed loop drilling processes that reduce the need for pit liners in energy exploration, could also reduce demand for the Company’s products.

Aerostar’s future growth relies on sales of high-altitude balloons, as well as advanced radar systems and aerostats to international markets. In limited cases, such sales may be Direct Commercial Salesdirect commercial sales to foreign governments rather than Foreign Military Salesforeign military sales through the U.S. government. Direct Commercial Salescommercial sales to foreign governments often involve large contracts subject to frequent delays because of budget uncertainties, regional military conflicts, political instability, and protracted negotiation processes. Such delays could adversely affect our results of operations. The nature of these markets for certain of Aerostar's advanced radar systems and aerostats makes these products particularly susceptible to fluctuations in market demand. Demand fluctuations and the likelihood of delays in sales involving large contracts for such products also increase the risk of these products becoming obsolete, increasing the risk associated with expected sales of such products. The value of certain advanced radar systemsystems and aerostat inventory are each approximately $4 million at January 31, 2017.2018 was $1.6 million and $3.4 million, respectively. This valuation is based on an estimate that the market demand for these products will be sufficient in future periods such that these inventories will be sold at a price greater than carrying value.value and related selling costs. Write-downs or impairment of the value of such products carried in inventory could adversely affect our results of operations. To the extent products become obsolete or anticipated sales are not realized, our expected future cash flows could be adversely impacted. This could also lead to an impairment, which could adversely impact the Company's results of operations and financial condition.

  

Sales of certain of Aerostar’s products into international markets increase the compliance risk associated with regulations such as The International Traffic in Arms Regulations (ITAR),and Foreign Corrupt Practices Act, as well as others, exposing the Company to fines and its employees to fines, imprisonment, or civil penalties. Potential consequences of a material violation of such regulations include damage to our reputation, litigation, and increased costs.

A significant portion of Aerostar's sales are to the U.S. government or U.S. government agencies as a prime or sub-contractor. Government spending has historically been cyclical. A decrease in U.S. government defense or near-space research spending or changes in spending allocations could result in one or more of the Company's programs being reduced, delayed, or terminated. Reductions in the Company's existing programs, unless offset by other programs and opportunities, could adversely affect its ability to sustain and grow its future sales and earnings. The Company's U.S. government sales are funded by the federal budget, which operates on an October-to-September fiscal year. Changes in congressional schedules, negotiations for program funding levels, reduced program funding due to U.S government debt limitations, automatic budget cuts ("sequestration"), or unforeseen world events can interrupt the funding for a program or contract. Funds for multi-year contracts can be changed in subsequent years in the appropriations process.

In addition, many U.S. government contracts are subject to a competitive bidding and funding process even after the award of the basic contract, adding an additional element of uncertainty to future funding levels. Delays in the funding process or changes in funding are common and can impact the timing of available funds or can lead to changes in program content or termination at the government's convenience. The loss of anticipated funding or the termination of multiple or large programs could have an adverse effect on the Company's future sales and earnings.

The Company's consolidated net sales to locations outside of the U.S. were $35.5$41.6 million in fiscal 2017,2018, representing approximately 13%11% of consolidated net sales. The Company's financial results could be affected by changes in trade, monetary and fiscal policies, laws and regulations, or other activities of U.S. and non-U.S. governments, agencies and similar organizations, along with changes in worldwide economic conditions. These conditions include, but are not limited to, changes in a country's or region's economic or political condition; trade regulations affecting production, pricing, and marketing of products; local labor conditions and regulations; reduced protection of intellectual property rights in some countries; changes in the regulatory or legal environment; restrictions on currency exchange activities; the impact of fluctuations in foreign currency exchange rates, which may affect product demand and may adversely affect the profitability of our products in U.S. dollars in foreign markets where payments are made in the local currency; burdensome taxes and tariffs; and other trade barriers. International risks and uncertainties also include changing social and economic conditions, terrorism, political hostilities and war, difficulty in enforcing agreements or collecting receivables, and increased transportation or other shipping costs. Any of these such risks could lead to reduced sales and reduced profitability associated with such sales.

The Company's results of operations are impacted by the market fundamentals of the primary industries served. Significant declines of economic activity in the agricultural, oil and gas exploration, construction, industrial, aerospace/defense, and other major markets served may adversely affect segment performance and consolidated results of operations.

The Company's business strategy includes pursuing future acquisitions. Acquisitions involve a number of risks, including integration of the acquired company with the Company's operations and unanticipated liabilities or contingencies related to the acquired company. Further, business strategies supported by the acquisition may be in perceived, or actual, opposition to strategies of certain of our customers and our business could be materially adversely affected if those relationships are terminated and the expected strategic benefits are delayed or are not achieved. The Company cannot ensure that the expected benefits of any acquisition will be realized. Costs could be incurred on pursuits or proposed acquisitions that have not yet or may not close, which could significantly impact the operating results, financial condition, or cash flows. Additionally, after the acquisition, unforeseen issues could arise, which adversely affect the anticipated returns or which are otherwise not recoverable as an adjustment to the purchase price. Other acquisition risks include delays in realizing benefits from the acquired companies or products; difficulties due to lack of or limited prior experience in any new product or geographic markets we enter; unforeseen adjustments, charges or write-offs; unforeseen losses of customers of, or suppliers to, acquired businesses; difficulties in retaining key employees of the acquired businesses; or challenges arising from increased geographic diversity and complexity of our operations and our information technology systems.

Total goodwill and intangible assets accountaccounted for $52.7$57.3 million, or approximately 17%18%, of the Company's total assets as of January 31, 2017.2018. The Company evaluates goodwill and intangible assets for impairment annually, or when evidence of potential impairment exists. The annual impairment test is based on several factors requiring judgment. Principally, a significant decrease in expected cash flows or changes in market conditions may indicate potential impairment of recorded goodwill or intangible assets. Our expected future cash flows are dependent on several factors, including revenue growth in certain of our product lines and an expectation that the pricing in commodities markets will recover in future periods.lines. Our expected future cash flows could be adversely impacted if our anticipated revenue growth is not realized or if pricing in commodities markets does not recover in future periods. Reductions in cash flows could result in an impairment of goodwill and/or intangible assets, which could adversely impact the Company's results of operations and financial condition.

We depend on the performance of our board of directors, senior management team and other key employees, including experienced and skilled technical personnel.  The loss of certain members of our board of directors, senior management, including our Chief Executive Officer, or other key employees, could negatively impact our operating results and ability to execute our business strategy.  Our future success will also depend, in part, upon our ability to attract, train, motivate, and retain qualified board members, senior management and other key personnel.

The Company has developed significant proprietary technology and other rights that are used in its businesses. The Company relies on trade secret, copyright, trademark, and patent laws and contractual provisions to protect the Company's intellectual property. While the Company takes enforcement of these rights seriously, other companies, such as competitors or persons in related markets, may attempt to copy or use the Company's intellectual property for their own benefit.

In addition, intellectual property of others also has an impact on the Company's ability to offer some of its products and services for specific uses or at competitive prices. Competitors' patents or other intellectual property may limit the Company's ability to offer products and services to its customers. Any infringement or claimed infringement by the Company ofon the intellectual property rights of others could result in litigation and adversely affect the Company's ability to continue to provide, or could increase the cost of providing, products and services and negatively impact sales and profitability. Any infringement by the Company could also result in judgments against the Company, which could adversely affect our results of operations, financial condition, liquidity, and cash flows.

Regardless of the merit of any such claims, litigation is often very costly, time-consuming, and disruptive to the operations and business of the Company, and a distraction to management and other personnel. While these matters generally are not material in nature, it is possible a matter may arise that is material to the Company’s legal proceedingsbusiness.

Although the Company believes the probability of a materially adverse outcome is a patent infringement lawsuit filed in federal district court in Kansas by Capstan Ag Systems, Inc. In this lawsuit, Capstan Ag Systems Inc. has made certain infringementremote, if one or more claims were resolved against the Company and onein a reporting period for amounts in excess of its customers, CNH Industrial America LLC, related tomanagement’s expectations, the Applied Technology Division’s Hawkeye™ nozzle control system.  This litigation is in the early stages and the potential costs and liability of this pending claim, if any, cannotCompany’s consolidated financial statements may be determined at this time.

The Company increasingly relies on information technology systems to process, transmit, and store electronic information. In addition, a significant portion of internal communications, as well as communication with customers and suppliers, depends on information technology. Further, the products in our Applied Technology and Aerostar segments depend upon GPS and other systems through which our products interact with government computer systems and other centralized information sources. We are exposed to the risk of cyber incidents in the normal course of business. Cyber incidents may be deliberate attacks for the theft of intellectual property or other sensitive information or may be the result of unintentional events. Like mostother companies, the Company's information technology systems may be vulnerable to interruption due to a variety of events beyond the Company's control, including, but not limited to, natural disasters, terrorist attacks, telecommunications failures, computer viruses, hackers, foreign governments, and other security issues. Further, attacks on centralized information sources could affect the operation of our products or cause them to malfunction. The Company has technology security initiatives and disaster recovery plans in place to mitigatemanage the Company's risk to these vulnerabilities, but these measures may not be adequate, or implemented properly, or executed timely to ensure that the Company's operations are not significantly disrupted. Potential consequences of a material cyber incident include damage to our reputation, litigation, and increased cyber security protection and remediation costs. Such consequences could adversely affect our results of operations.
