Agtech
The Agtech segment designs, manufactures, and installs high-technology turnkey greenhouse facilities designed for large-scale indoor growing production of fruits and vegetables, plants and flowers, and agricultural research and development facilities with over 100 universities in the United States. Large scale greenhouse facilities are unique to a particular type of plant, vegetable, flower, or fruit, and require unique structures, growing systems, and the integration of the structure and the systems.
Infrastructure
The Infrastructure segment serves highway and bridge construction and airports through commercial and transportation contractors. The Company's products include expansion joints, structural bearings, rubber pre-formed seals and other sealants, elastomeric concrete, and bridge cable protection systems. Infrastructure's products are manufactured primarily from plate and structural steel along with various resin and rubber based materials.
New products introduced in recent years extend the infrastructure products into new markets. For example, its engineered pavement sealants for roadways are now being installed on airport runways, its structural bearings for elevated highways and bridges have been installed on offshore oil production platforms, and its corrosion-protection products for cable-suspension bridges are now marketed and sold internationally.
Engineering and Technical Services
The Company's business segments employ engineers and other technical personnel to perform a variety of key tasks which include the identification and implementation of improvements to its manufacturing process, redesign of its products for better performance, the development of new products and identification and execution of cost reduction activities. In addition, the Company's engineering staff employs a range of software to design highly specialized and technically precise products. In the Renewables, Agtech, and Infrastructure segments, drawings are approved and stamped by state licensed professional engineers as required by individual projects. Technical service personnel also work in conjunction with the Company's sales force in the new product development process to determine the types of products and services that suit the particular needs of customers.
Suppliers and Raw Materials
The Company's business is required to maintain sufficient quantities of raw material inventory in order to accommodate customers delivery requirements. Accordingly, the Company plans its purchases to maintain raw materials at sufficient levels to satisfy the anticipated needs of customers. The Company has implemented enterprise resource planning systems along with a corporate wide SIOP (Sales, Inventory, Operations Planning process) to better manage inventory, forecast customer orders, enable efficient supply chain management, and allow for timely counter-measures to changing market conditions.
The primary raw materials the Company purchases are flat-rolled, structural and plate steel, aluminum coil and extrusions, and resins. The Company purchases flat-rolled and plate steel and aluminum at regular intervals on an as-needed basis, primarily from the major North American mills, as well as, a limited amount from domestic service
8

Table of Co n tents
centers and foreign steel importers. Substantially all of its resins are purchased from domestic vendors, primarily through distributors, with a small amount purchased directly from manufacturers. Management continually evaluates improvements in the Company's purchasing practices across its geographically dispersed facilities in order to streamline purchasing across similar commodities.
The Company purchases natural gas and electricity from suppliers in proximity to its operations.
Intellectual Property
The Company actively protects its proprietary rights by the use of trademark, copyright, and patent registrations. While the Company does not believe that any individual item of its intellectual property is material, the Company believes its trademarks, copyrights, and patents provide the Company with a competitive advantage when marketing its products to customers. The Company also believes its brands are well recognized in the markets it serves and the Company believes the brands stand for high-quality manufactured goods at a competitive price. These trademarks, copyrights, and patent registrations help the Company maintain product leadership positions for the goods it offers.
Sales and Marketing
In 2022, approximately 45% of the Company's revenues were generated from products and services that were sold directly to the end user, with the remainder of revenues generated through retailers, wholesalers and distributors, down from 56% in 2021. The Company's sales process regularly includes a competitive bid process, and its reputation for product and service quality and meeting delivery requirements make the Company a preferred provider for many customers.
The Company shifted its marketing focus in 2021 to build an enhanced cohesive brand strategy—ensuring the Company has a defined purpose and values and ensuring the Company's brand messages reflect the needs of the market and the capabilities of its businesses. The businesses in the Company's Renewables segment were integrated and rebranded under the brand name Terrasmart at the beginning of 2022 and the Company's businesses in its Agtech segment were consolidated under the brand name Prospiant during 2021. In their markets, both brands reflect the Company's unique value to customers.
In 2021, the Company began to expand and upgrade its Customer Relationship Management (CRM) system, which work continued into 2022, thus improving its visibility into sales account status and enabling cross-sell and up-sell opportunities. The CRM also provides important aggregate market data.
Backlog
Backlog represents the value of the total confirmed orders at a point in time for which performance obligations have not yet been satisfied. Only actual orders with signed contracts are included in the Company's backlog. This metric is useful as it reflects the committed amount the Company expects to recognize as revenue in the near-term.
While the majority of the Company's products have short lead time order cycles, the Company has aggregated approximately $299 million of backlog from continuing operations at December 31, 2022 compared to $344 million at December 31, 2021. The backlog primarily relates to certain business units in the Company's Renewables, Agtech, and Infrastructure segments. The Company believes that the performance obligations related to the majority of its backlog will be satisfied and related revenue recognized during 2023.
Competition
The Company operates in highly competitive markets with several competitors participating in each of its end markets. The Company goes to market with a focused and broad range of high quality products, executes with speed and industry-leading service, value-based pricing and project management and field operations in its Agtech and Renewables businesses.
Seasonality
The Company’s end markets have historically experienced seasonal demand fluctuation, with lower demand typically in the first and fourth quarters. Levels of residential and commercial construction can be cyclical and can depend on interest rates, availability of financing, inflation, employment, spending habits, consumer confidence and cost and availability of skilled labor. Furthermore, general economic forces, such as tax credit expirations and imposed tariffs, the impact of the COVID-19 pandemic, and changes in the Company’s products and customer mix
9

Table of Co n tents
can and have shifted traditional seasonal fluctuations in revenue over the past few years. As the pandemic is subsiding and tax credits for the Company's renewable energy customers begin to stabilize, the Company has seen a shift back towards traditional seasonality with the fourth quarter of 2022 being slower than experienced in 2021 and 2020.
Governmental Regulation
The Company's production processes involve the use of environmentally regulated materials. The Company believes that the Company operates its business in material compliance with all federal, state and local environmental laws and regulations, and does not anticipate any material adverse effect on its financial condition or results of operations to maintain compliance with such laws and regulations. However, the Company could incur operating costs or capital expenditures in complying with new or more stringent environmental requirements in the future or with current requirements if they are applied to its manufacturing facilities or distribution centers in a way the Company does not anticipate. In addition, new or more stringent regulation of the Company's energy suppliers could cause them to increase the price of energy.
The Company's operations are also governed by many other laws and regulations covering its labor relationships, the import and export of goods, the zoning of its facilities, taxes, its general business practices, and other matters. The Company believes that it is in material compliance with these laws and regulations and does not believe that future compliance with such laws and regulations will have a material adverse effect on its financial condition or results of operations.
Human Capital - Organization Development
The foundation for the Company's focus on organizational development is built on two fundamental beliefs:
•The Company's ability to perform and deliver shareholder value is dependent on our people, and
•The Company strives to create an environment where our people can have the best chance to thrive, which the Company refers to internally as creating the "Best Place to Work."
The Company's "Best Place to Work" initiative engages the entire organization, with areas of focus that include Health and Safety, Education and Development, Diversity and Inclusion, Compensation and Employee Benefits, and Communication and Employee Engagement.
The Company employed 2,117 full-time employees and 20 part-time employees as of December 31, 2022. Of the Company's 2,137 total employees, 876 were classified as salary and 1,261 classified as hourly. The Company also employed approximately 329 full-time equivalent temporary agency employees. Approximately 6% of the Company's U.S. workforce was represented by unions through two collective bargaining agreements ("CBAs") as of December 31, 2022. Both of the Company's CBAs will expire and are expected to be renegotiated in 2024. The Company considers its employee relations to be good.
Health and Safety
The Company expects each team member of the Company to follow the Company's safety standards and practices, support the Company's key safety initiatives, be accountable to themselves and each other, and be part of safety solutions. The Company believes all accidents and near-misses are preventable as the Company strives to create a zero incidents work environment.
The Company has continued to invest in the Company's safety organization, and implemented a disciplined safety management and reporting process, measuring and reviewing the Company's safety results continuously in each location. The Company's CEO reviews safety performance monthly, including recordable incidents, near misses, and first aid cases. Safety performance and best practices are also reviewed quarterly with the entire organization during company-wide Town Hall meetings and with the Company's Board of Directors during quarterly board meetings.
Each of the Company's businesses have a safety team that assesses all recordable incidents and near misses to identify mitigating actions to prevent accidents in the future. The Company's businesses also identify additional safety investments required for training, education, equipment, and processes as part of the Company's annual budget and capital planning procedure.

Table of Co n tents
The Company is continuously evolving its crisis management plans as the Company gains experience, reviews industry best practices, and continues to develop more effective tools, processes, and policies. In an emergency, the Company's priorities are to protect the welfare of our people and to maintain business continuity.
Diversity and Inclusion
The Company supports and encourages a culture where diversity of thought flourishes and all employees feel appreciated, included, and know they have an equal opportunity to develop, grow, and succeed based on their performance. The Company believes demonstrating respect for our people and valuing their perspectives and their contributions is critical to cultivating the Company's best and most successful work environment, a belief that is foundational for the Company's “Best Place to Work” initiative.
Key demographics for the Company's employees are shown below. While the figures below are in total, the Company evaluates its organization against the diversity of the communities that the Company operates in, with a goal of being representative at the community level.

Item 1A. | Risk Factors

The Company's business, financial condition and results of operations, and the market price for its common stock are subject to numerous risks, many of which are driven by factors that cannot be controlled or predicted. The following discussion, as well as other sections of this Annual Report on Form 10-K, including “Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations,” describe certain business and other risks affecting the Company. In conjunction with reviewing the forward-looking statements and other information contained in this Annual Report on Form 10-K, consideration should be given to the risk factors described below as well as those in the Safe Harbor Statement at the beginning of this Annual Report on Form 10-K. These risks are not the only risks to which the Company is exposed. The Company's business operations and the market for its securities could also be adversely affected by additional factors that are not presently known to the Company, or that it currently considers to be immaterial to its operations.

Risks Related to the Company's Business Operations
The volatility of the commodity market with respect to the Company's principal raw materials and component parts, or substantial decreases in the availability of the Company's principal raw materials and component parts, has impacted, and could continue to impact, the Company's business, results of operations, and cash flows.
The Company's principal raw materials are commodity products primarily consisting of steel, aluminum, and resins. The Company also purchases component parts such as glass for greenhouse roofing systems thus resulting in exposure to changes in the price and availability of glass, and furthermore, although not purchased by the Company, the Company also has exposure related to the availability of solar panels which has impacted the installation of, and which can and has reduced demand for, the Company's solar racking projects, as experienced in 2022. As the Company has seen with the broader market dynamics in 2022, and potentially continuing in 2023, availability and pricing of raw materials can be volatile due to a number of factors beyond its control, including general economic conditions, domestic and worldwide supply and demand, labor costs and availability, competition, freight costs and transportation, import duties, tariffs, and currency exchange rates. The Company has been impacted by cost increases and disruptions to the Company's supply deliveries, which disruptions have subsided in the latter part of 2022.
The Company may not be successful in passing along pricing increases to its customers or in its efforts to mitigate the impact of supply chain disruptions. The failure by the Company's suppliers to deliver raw materials or component parts according to schedule, or at all, has resulted in manufacturing delays, capacity constraints, project delays, cost inflation and logistics delays and has affected, and may continue to affect, the Company's ability to meet its customers' needs. Furthermore, the failure of any sourced raw materials or components to conform to the Company's specifications could also result in delays in its ability to timely deliver, and may have an adverse impact on the Company's relationships with its customers and its ability to fully realize the revenue expected from sales to those customers.
In addition, commodity price fluctuations and increased competition could force the Company to lower its prices or to offer additional services or enhanced products at a higher cost to the Company, which could reduce the Company's gross profit, net income, and cash flow and cause the Company to lose market share.
Macroeconomic factors outside of the Company's control may adversely affect its business, its industry, and the businesses and industries of many of its customers and suppliers.
Macroeconomic factors have a significant impact on the Company's business, customer demand and the availability of credit and other capital, affecting the Company's ability to generate profitable margins. The Company's operations are subject to the effects of domestic and international economic conditions, including global industrial production rates, inflation, deflation, interest rates, availability of capital, debt levels, consumer spending, energy availability, commodity prices, and the effects of governmental initiatives to manage economic conditions, including government monetary and trade policies, tax laws and regulations. Tariffs placed on imported products used by the Company's customers, such as solar panels, could impact cost and availability of these products to the Company's customers which could impact the demand for the Company's products or services. In addition, fluctuations in the U.S. dollar impact the prices the Company charges and costs it incurs to export and import products. The Company is unable to predict the impact on its business of changes in domestic and international economic conditions. The Company currently faces challenging market conditions, and domestic or global economies, or certain industry sectors of those economies that are key to the Company's sales, may further deteriorate, which could result in a corresponding decrease in demand for the Company's products and negatively impact the Company's results of operations and financial condition.
In reference to aforementioned tariffs on imported solar panels, the United States currently imposes antidumping and countervailing duties ("AD/CVD") on certain imported solar panels and components from certain countries in Southeast Asia. The AD/CVD can change over time pursuant to annual reviews conducted by the U.S. Department of Commerce ("USDOC"), and a change in duty rates could have an adverse impact on the Company's operating results. In early 2022, the USDOC was petitioned to investigate alleged circumvention of AD/CVD on Chinese imports of solar panels and components produced in other countries in Southeast Asia. In March 2022, the USDOC announced that it would investigate the circumvention alleged in the petition and in December 2022, it issued a preliminary report that found occurrences of the alleged circumvention. Concurrent with this investigation, in June 2022, the President of the United States issued an Executive Order to suspend any tariffs that result from this investigation for two years.
13

Furthermore, in June 2022, the Uyghur Forced Labor Prevention Act ("UFLPA") was enacted. The UFLPA requires traceability of components of imported goods to validate that the components are not sourced from areas in the Xinjiang region of China, which may be held at U.S. customs until the importer is able to prove where they have been sourced.
As the timing and progress of many of the Company's customers’ projects depend upon the supply of solar panels and components, the Company's operating results have been impacted by the disruption resulting from the above investigation and validation procedures. The Company's operating results could be further adversely impacted by any final negative circumvention determinations made by the USDOC and continued timing lag of review by U.S. customs.
The success of the Company's business depends on the Company's senior management team, as well as other key employees and the Company's ability to attract, retain, develop and motivate a skilled and diverse workforce.
The Company's success is dependent on the management and leadership skills of its senior executive and divisional management teams. The Company has had recent changes in the senior executive team that were planned and/or are expected to be mitigated, however, the Company cannot assure you that the Company will be able to retain its existing senior management personnel, or that the Company will have a successor prepared and available upon any loss of such personnel, or that the Company will be able to attract additional qualified personnel through external recruitment when needed. The Company has not entered into employment agreements with any of its senior management personnel.
Additionally, the Company may not be able to successfully compete for, attract, retain, develop or motivate a skilled and diverse workforce that the Company's business may require. The Company's business is dependent on engineers and other technical personnel to execute a variety of key responsibilities which include, but are not limited to, the identification and implementation of improvements to the Company's manufacturing process, redesign of the Company's products for better performance, the development of new products, and the identification and execution of cost reduction activities. Also, technical service personnel work in conjunction with the Company's sales force in the new product development process to determine the types of products and services that suit the particular needs of the Company's customers. Furthermore, the Company's business may be adversely impacted by the availability of labor at its manufacturing and distribution facilities, or in the field at its customers' project sites. The unexpected loss of a member of the Company's senior management team, key employee or highly-skilled associate, including due to an increase in aggressive recruiting for talent in the current labor market, or the Company's inability to attract and retain additional personnel could deplete the Company's institutional knowledge base, erode the Company's competitiveness and prevent the Company from successfully executing its business strategy.
The COVID-19 pandemic has significantly impacted worldwide economic conditions and adversely impacted, and may continue to adversely impact the Company's business, results of operations, financial condition, and cash flows.
The COVID-19 pandemic began to impact the Company's operations late in the first quarter of 2020 as government authorities imposed mandatory closures, work from home orders and social distancing protocols, which resulted in temporary curtailment of some operations and increased costs to operate certain facilities, and has continued to impact the Company's operations as new strains of the COVID-19 virus have been identified.
During 2021 and to a lesser extent in 2022, the COVID-19 pandemic, as well as broader market dynamics have resulted in impacts to the Company's business, including increased material cost inflation, labor availability issues (due to illness and otherwise) and logistics challenges and costs increases and were impacted by supply constraints for materials and commodities used in the Company's operations.
It is not possible to predict the ultimate impact of the COVID-19 pandemic, as well as the emergence of new virus strains and availability of effective treatment on the Company's business, results of operations, financial position or cash flows, and the duration of such impact may vary dramatically by geography and line of business. However, while the COVID-19 pandemic subsides, the Company may experience continued adverse impacts of this pandemic on the Company's business and financial statements, including through disruptions to the supply chain, limiting access to the Company's distribution channels, reducing the availability of the Company's workforce and subcontractors and heightened cybersecurity risk, all of which may pose material risk to the Company's results of operations, financial condition, and cash flows. Further, the COVID-19 pandemic may exacerbate the potential
14

Table of Co n tents
impact of the other risks described herein on the Company's results of operations, financial condition and cash flows.
A significant portion of the Company's net sales are concentrated with a few customers. The loss of any of those customers would adversely affect the Company's business, results of operations, and cash flows.
A loss of sales, whether due to decreased demand from the end markets the Company serves, the loss or bankruptcy of any significant customer in these markets, a decrease in the prices that the Company can realize from sales of its products to customers in these markets, or a significant decrease in business from any of the Company's major customers, could have a significant adverse effect on the Company's profitability and cash flows. The Company's ten largest customers accounted for approximately 41%, 38%, and 35% of the Company's net sales during 2022, 2021, and 2020, respectively, with its largest customer, a retail home improvement center, accounting for approximately 14%, 13% and 14% of the Company's consolidated net sales during each of the years 2022, 2021, and 2020, respectively.
The Company's business is highly competitive and increased competition could reduce the Company's gross profit, net income, and cash flow.
The principal markets that the Company serves are highly competitive. Competition is based primarily on product functionality, quality, price, raw material and inventory availability, and the ability to meet delivery schedules dictated by customers. The markets in which the Company operates are characterized by changing technologies and introductions of new products and services, so the Company also faces competition from the introduction by competitors of new products or technologies. The Company competes in its principal markets with companies of various sizes, some of which have greater scale and financial and other resources than the Company, as well as have better established brand names and may be better able to withstand a change in conditions in the markets the Company serves. Increased competition could force the Company to lower its prices or to offer additional services or enhanced products at a higher cost to the Company, which could reduce the Company's gross profit, net income, and cash flow and cause the Company to lose market share. Further, if the Company does not have sufficient resources to invest or is otherwise unable to correctly identify customer needs and preferences, innovate and drive improvements or efficiencies in existing products, develop new products, technologies or services in the markets the Company participates in, or successfully commercialize its innovation efforts, the Company may lose market share. Even when the Company successfully innovates and develops new and enhanced products and services, the Company often incurs substantial costs in doing so, and the Company's profitability may suffer.
If the subcontractors the Company relies upon do not perform their contractual obligations, the Company's revenues and cash flows would be adversely affected.
Some of the Company's construction contracts with customers involve subcontracts with other companies that perform a portion of the services or provide systems that are integral to the end product that the Company provides to its customers. The Company depends on the quality and timeliness of work performed by its subcontractors. There is a risk the subcontractors may not perform their contractual obligations, which may subject the Company to customer concerns or disputes. Any such disputes or concerns could materially and adversely impact the Company's ability to perform the Company's obligations as the prime contractor.
The Company's operations are subject to seasonal fluctuations and the cyclical nature of construction activity that may impact the Company's cash flow.
The Company's net sales are generally lowest in the first quarter primarily as a result of reduced activity in the building industry due to inclement weather. Therefore, the Company's cash flow from operations may vary from quarter to quarter. Furthermore, construction activity has historically been cyclical and dependent on economic conditions, including interest rates, availability of financing, inflation, employment, spending habits, consumer confidence and other factors outside the Company's control. Residential and commercial construction is also affected by the cost and availability of skilled labor, which could impact both the cost and pace of construction activity, as well as the construction methods used, all of which could adversely affect demand for the Company's products. If the Company's cash flows were significantly reduced due to seasonal fluctuations or reduced construction activity, the Company may not be able to service its indebtedness or maintain covenant compliance.

The Company's ongoing and expected restructuring plans and other cost savings initiatives may not be as effective as the Company anticipates, and the Company may fail to realize the cost savings and increased efficiencies that the Company expects to result from these actions, which could negatively affect the Company's operating results.
The Company continually seeks ways to simplify or improve processes, eliminate excess capacity and reduce costs in all areas of its operations, which from time to time includes restructuring and integration activities. The Company has implemented significant restructuring activities across its manufacturing, sales and distribution footprint, which include workforce reductions and facility consolidations. Costs of future initiatives may be material and the savings associated with them are subject to a variety of risks, including the Company's inability to effectively eliminate duplicative back-office overhead and overlapping sales personnel, rationalize manufacturing capacity, synchronize information technology systems, consolidate warehousing and distribution facilities and shift production to more economical facilities. As a result, the contemplated costs to effect these initiatives may materially exceed estimates. The initiatives the Company is contemplating may require consultation with various employees and consultants which may influence the timing, costs and extent of expected savings and may result in the loss of skilled employees in connection with the initiatives.
If the Company is unable to implement its cost savings initiatives as timely and/or effectively as planned, the Company's business may be adversely affected by the impact of the Company's ability to continue to meet customer demand, maintain a high level of quality throughout the execution of the plans, and achieve the expected financial benefits of such plans, and therefore, potentially resulting in a material adverse effect on the Company's business, results of operations and financial condition.
Economic, political, and other risks associated with foreign operations could adversely affect the Company's financial results and cash flows.
Although the significant majority of the Company's business activity takes place in the United States, the Company derives a portion of its revenues and earnings from operations in Canada, China and Japan, and are subject to risks associated with doing business internationally. The Company's sales originating outside the United States represented approximately 4% of the Company's consolidated net sales during the year ended December 31, 2022. The Company believes that its business activities outside of the United States involve a higher degree of risk than the Company's domestic activities, such as the possibility of unfavorable circumstances arising from host country laws or regulations, changes in tariff and trade barriers and import or export licensing requirements and exposes the Company to currency exchange rate fluctuations between the United States Dollar and foreign currencies. In addition, any local or global health issue or uncertain political climates, international hostilities, natural disasters, or any terrorist activities could adversely affect customer demand, the Company's operations and the Company's ability to source and deliver products and services to the Company's customers.
Climate change and climate change legislation or regulations may adversely affect the Company's business.
Legislative and regulatory changes in response to the potential effects of climate change may require additional costs and investment for compliance, including an increase in the Company's capital expenditures to reduce the Company's greenhouse gas emissions and increased cost of purchased energy for both the Company and its suppliers, which may increase the Company's costs to procure raw materials, components or equipment parts. As climate change continues to increase the severity of weather, physical effects—such as damage to facilities, capital equipment and inventory or disruption in production, product distribution or field operations as a result of heat, drought, wildfires, major storm events and shifts in regional weather patterns and intensities—may also significantly affect the Company's operations and financial results. Concerns over global climate change and environmental sustainability over time, including due to expectations of the Company's stockholders, customers and employees, may influence the Company's strategic direction, supply chain, or delivery channels.
Future terror attacks, war, natural disasters or other catastrophic events beyond the Company's control could negatively impact the Company's operations and financial results.
Terror attacks, war, or other civil disturbances, natural or man-made disasters (which may become more frequent due to climate change), other catastrophic events or public health crises could cause catastrophic loss or other material damage to the Company's facilities or lead to economic instability, decreased capacity to produce the Company's products and decreased demand for the Company's products. The Company has experienced operating disruptions related to severe weather across the U.S. From time to time, terrorist attacks worldwide have caused instability in global financial markets. The Company does not conduct business in nor source directly from either

Russia or Ukraine yet continues to monitor the current military conflict between these countries for any potential disruptions. The Company could incur uninsured losses and liabilities arising from such events, and any resulting business interruptions could have an adverse effect on the Company's operations, cash flows and financial results.
Risks Related to Information Technology
The Company's business and financial performance may be adversely affected by cybersecurity attacks, information systems interruptions, equipment failures, and technology integration.
The Company relies on information technology ("IT") systems, some of which are provided and/or managed by third-parties, to process, transmit and store electronic information (including sensitive data such as confidential business information and personally identifiable data relating to the Company's employees, customers and other business partners), and to manage or support a variety of critical business processes and activities (such as receiving and fulfilling orders, billing, collecting and making payments, shipping products, providing services and support to customers, and fulfilling contractual obligations). The Company's ability to effectively manage its business depends on the security, reliability, and capacity of these IT systems. These systems (including those the Company acquires through business acquisitions) can be damaged, disrupted or shut down due to attacks by computer hackers, computer viruses, ransomware, human error or malfeasance, power outages, hardware failures, telecommunication or utility failures, catastrophes, or other unforeseen events. While, the Company maintains IT measures designed to protect the Company against intellectual property theft, data breaches, sabotage and other external or internal cyber-attacks or misappropriation, cyber-attacks are increasingly difficult to identify and prevent, and it is possible that potential vulnerabilities could go undetected for an extended period. The Company's systems are not fully redundant and the Company's disaster recovery planning may not be sufficient. Any interruptions to the Company's IT systems could disrupt the Company's operations, causing delays or cancellation of customer orders or impeding the manufacture or shipment of products, processing of transactions or reporting of financial results. Security breaches can result in the misappropriation, destruction or unauthorized disclosure of confidential information or personal data belonging to the Company or to the Company's employees, partners, customers, or suppliers, damage customer, business partner and employee relationships and the Company's reputation and result in legal claims and proceedings, liability and penalties under data protection laws and regulations. Some of the Company's IT systems have experienced past security breaches, and, although they did not have a material adverse effect on the Company's operating results, there can be no assurance that future incidents will not have material adverse effects on the Company's operations or financial results.
In addition, the Company's IT systems require an ongoing commitment of significant resources to maintain and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving legal and regulatory standards and customer expectations, changes in the techniques used to obtain unauthorized access to data and information systems, and the IT needs associated with the Company's changing products and services. In addition, the Company is subject to data privacy and security laws, regulations, and customer-imposed controls in a number of jurisdictions as a result of having access to and processing confidential, personal and/or sensitive data in the course of the Company's business. Compliance with the varying data privacy regulations across the United States and around the world has required, and will continue to require, significant expenditures. There can be no assurance that the Company will be able to successfully maintain, enhance and upgrade the Company's IT systems as necessary to effectively address changing cybersecurity risks and legal requirements, and the Company's efforts to do so may be costly.
Risks Related to Acquisitions
The Company's strategy depends, in part, on identification, management and successful business and system integration of future acquisitions.
Historically, the Company has grown through a combination of internal growth plus external expansion through acquisitions. The Company intends to continue to seek additional acquisition opportunities in accordance with the Company's business strategy. However, the Company cannot provide any assurance that the following risks involved in completing acquisitions will not occur nor adversely impact the Company's operations and financial results:
•Failure to identify appropriate acquisition candidates, or, if the Company does, failure to successfully negotiate the terms of an acquisition;
•Diversion of senior management’s attention from existing business activities;
•Failure to integrate any acquisition into the Company's operations successfully;
17

Table of Co n tents
•Unforeseen obligations, loss of key customers, suppliers, and employees of the acquired businesses, or loss of existing customers and suppliers;
•Difficulties or delays in integrating and assimilating information and systems that may require significant unforeseen upgrades or replacement of the Company's primary IT systems across significant parts of the Company's businesses and operations, which could lead to interruptions of information flow internally and to the Company's customers and suppliers;
•The need to raise additional funds through additional equity or debt financing, which could be dilutive to stockholder value, increase the Company's interest expense and reduce the Company's cash flows and available funds; and
•Adverse impact on overall profitability if the acquired business does not achieve the return on investment projected at the time of acquisition.
Risks Related to Financing and Accounting Matters
The Company applies judgments and makes estimates in accounting for certain customer contracts, and changes in these judgments or estimates may have significant impacts on the Company's earnings.
Changes in judgments or required estimates and any subsequent adjustments to those judgments or estimates (such as performance incentives, penalties, contract claims and contract modifications) could have a material effect on the Company's sales and profits. Due to the substantial judgments applied and estimations involved with the Company's accounting for customer contracts, the Company's actual results could differ materially or could be settled unfavorably from the Company's estimates. Revenue representing 40%, 47% and 40% of 2022, 2021 and 2020 of the Company's consolidated net sales, respectively, were recognized over time under the cost-to-cost method. Refer to “Critical Accounting Estimates” within Item 7 of this Annual Report on Form 10-K for more detail of how the Company's financial statements can be affected by accounting for revenue from contracts with customers.
If events occur or indicators of impairment are present that may cause the carrying value of long-lived and indefinite-lived assets to no longer be recoverable or to exceed the fair value of the asset, or that may lead to a reduction in the fair value of the asset, significant non-cash impairment charges to earnings may be taken that may have a material adverse impact on the Company's results of operations.
The Company has previously recorded significant non-cash impairment charges for goodwill and other intangible assets as a result of reductions in the estimated fair values of certain businesses. It is possible that the Company will be required to record additional non-cash impairment charges to the Company's earnings in the future, which could be significant and have a material adverse impact on the Company's results of operations. Refer to “Critical Accounting Estimates” within Item 7 of this Annual Report on Form 10-K for more detail of how the Company's financial statements can be affected by asset impairment.
Increases in future levels of leverage and size of debt service obligations could adversely affect the Company's ability to raise additional capital to fund the Company's operations, limit the Company's ability to react to changes in the economy or the Company's industries and prevent the Company from meeting the Company's obligations.
As of December 31, 2022, the Company had $91.0 million of outstanding indebtedness. The Company's ability to make scheduled payments on, or refinance, its debt obligations depend on the Company's financial condition and operating performance, which are subject to prevailing economic, industry and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond the Company's control. The Company may need to incur additional debt in the future to fund strategic acquisitions, investments or for other purposes, which debt could have significant adverse consequences to the Company's business. Any sustained weakness in general economic conditions and/or U.S. or global capital markets could adversely affect the Company’s ability to raise capital on favorable terms or at all. The Company’s access to funds under its credit facility is dependent on the ability of the financial institutions that are parties to that facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Longer term volatility and continued disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation of financial institutions, reduced alternatives or failures of significant financial institutions could adversely affect the Company’s access to the liquidity needed for its businesses in the longer term. Such disruptions could require the Company to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for its business needs can be arranged. The Company's Credit Agreement entered into on December 8, 2022, contains several financial and other restrictive covenants. A significant decline in the
18

Table of Co n tents
Company's operating income or use of the Company's Credit Agreement (or other additional indebtedness) for acquisitions, operations and capital expenditures could cause the Company to violate these covenants which could result in the Company incurring additional financing fees that would be costly and adversely affect the Company's profitability and cash flows.
Risks Related to Legal and Regulatory Matters
A portion of the Company's business is dependent on laws and regulations pertaining to the cannabis industry, and this industry faces significant opposition that could adversely affect this portion of the Company's business.
One of the Company's businesses makes and sells greenhouses which may be sold to companies that cultivate, process and sell cannabis products for recreational and medicinal use. This business is dependent on state laws and regulations pertaining to the cannabis industry that legalize and regulate cannabis use. While several states have legalized cannabis for medical or recreational purposes, it remains illegal under federal law. Even in those states in which cannabis use has been legalized, its use remains a violation of federal criminal law, which preempts state laws that legalize its use. Strict enforcement of federal law regarding cannabis would likely have an adverse impact on the Company's customers, and correspondingly, may adversely impact the Company's gross profit, net income and cash flows.
The cultivation, processing and distribution of cannabis in states where it has been legalized is subject to significant regulatory requirements. If the Company's customers who purchase greenhouses are unable to obtain and maintain the licenses, permits, authorizations or accreditations required to comply with state and local regulations, the Company may experience adverse effects on the Company's business and results of operations.
The Company's business that engages in the sale of greenhouses is dependent, in part, on increasing legalization and market acceptance of medical and recreational cannabis use. The Company cannot predict the future increase in state legalization or the future market potential of legalized cannabis use. Other well-established business sectors with powerful economic influence may take action that could adversely impact the cannabis market. The failure of further legalization or market acceptance, or the adverse action by competing well-established business sectors, may suppress the Company's customers’ demand for the Company's products and thereby reduce the Company's gross profit and net income.
Imposed tariffs and potential future tariffs may result in increased costs and could adversely affect the Company's results of operations.
Tariffs imposed in the United States on certain steel and aluminum products imported into the U.S. have created volatility in the market and have increased the costs of these inputs. Increased costs for imported steel and aluminum products have led domestic sellers to respond with market-based increases to prices for such inputs as well. These tariffs, along with any additional tariffs or trade restrictions that may be implemented by the U.S. or other countries, could result in further increased costs, shifting in competitive positions and a decreased available supply of steel, resins and aluminum as well as additional imported components and inputs. The Company may not be able to pass price increases on to its customers and may not be able to secure adequate alternative sources of steel, resins and aluminum on a timely basis. While retaliatory tariffs imposed by other countries on U.S. goods have not yet had a significant impact, the Company cannot predict further developments. The tariffs could adversely affect the Company's income from operations for some of the Company's businesses and customer demand for some of the Company's products which could have a material adverse effect on the Company's results of operations, financial position and cash flows.
The expiration, elimination or reduction of solar rebates, credits and incentives may adversely impact the Company's business.
A variety of federal, state and local government agencies provide incentives to promote electricity generation from renewable sources such as solar power. These incentives are in the form of rebates, tax credits and other financial incentives which help to motivate end users, distributors, system integrators and others to install solar powered generating systems. Any changes to reduce, shorten or eliminate the scope and availability of these incentive programs could materially and adversely impact the demand for the Company's related products, and the Company's financial condition and results of operations.
The timing and progress of many of the Company's renewable energy customers’ projects are impacted by incentives provided by the Federal solar tax credit also known as Investment Tax Credit ("ITC"). The recent Inflation

Reduction Act ("IRA") signed into law on August 16, 2022, provides a 30% ITC for projects started prior to the guidance issued by the Department of the Treasury and published in the Federal Register on November 30, 2022. Sixty days after the issuance of such guidance, January 29, 2023, the base ITC will be reduced to 6%. In order for the Company's customers to attain an additional 24% for a total credit of 30%, new labor requirements for the new wage and apprenticeship standards must be met. Demand for the Company's products could be adversely impacted if the Company does not meet the above standards in order to enable its customer to obtain the full 30% credit.
The nature of the Company's business exposes the Company to product liability, product warranty and other claims, and other legal proceedings.
The Company is involved in product liability, product warranty and other claims relating to the products the Company manufactured and distributed. Although the Company currently maintains what the Company believes to be suitable and adequate insurance in excess of the Company's self-insured amounts for product liability and other claims, there can be no assurance that the Company will be able to maintain such insurance on acceptable terms or that such insurance will provide adequate protection against potential liabilities. Product liability claims can be expensive to defend and can divert the attention of the Company's management and other personnel for significant periods, regardless of the ultimate outcome. Claims of this nature could also have a negative impact on customer confidence in the Company's products, the Company's brands and the Company. In the ordinary course of business, the Company is also subject to other types of legal and regulatory proceedings. Any claims raised in legal and regulatory proceedings, whether with or without merit, could be time consuming and expensive to defend and could divert the Company's management attention and resources. The Company cannot assure you that any current or future claims will not adversely affect the Company's reputation, financial condition, operating results, and cash flows.
The Company could incur substantial costs in order to comply with, or to address any changes in or violations of, environmental, health, safety and other laws.
The Company's operations and facilities are subject to a variety of stringent federal, state, local, and foreign laws and regulations, including those relating to the protection of the environment and human health and safety. Compliance with these laws and regulations sometimes involves substantial operating costs and capital expenditures, and failure to maintain or achieve compliance with these laws and regulations or with the permits required for the Company's operations could result in substantial costs and liabilities, such as fines and civil or criminal sanctions, third-party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations, including claims arising from the businesses and facilities that the Company has sold. The Company is subject to the risk that the Company, its employees, its affiliated entities, contractors, agents or their respective officers, directors, employees and agents may take actions determined to be in violation of any of these laws, for which the Company might be held responsible, particularly as the Company expands its operations geographically through organic growth and acquisitions. The Company cannot provide assurance that the Company's internal controls and compliance systems, including the Company's Code of Ethics and Statement of Policy, will protect the Company from acts committed by the Company's employees, agents or business partners that violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, kickbacks and false claims, pricing, sales and marketing practices, conflicts of interest, competition, employment practices, workplace behavior, export and import compliance, economic and trade sanctions, money laundering and data privacy. An actual or alleged violation could result in substantial fines, sanctions, civil or criminal penalties, debarment from government contracts, curtailment of operations in certain jurisdictions, competitive or reputational harm, litigation or regulatory action and other consequences that might adversely affect the Company's results of operations, financial condition or strategic objectives. For certain businesses the Company has divested, the Company has provided limited indemnifications for environmental contamination to the successor owners. The Company has also acquired and expects to continue to acquire businesses and facilities to add to the Company's operations. While the Company sometimes receives indemnification for pre-existing environmental contamination, the party providing the indemnification may not have sufficient resources to cover the cost of any required measures. Certain facilities of the Company have been in operation for many years and the Company may be liable for remediation of any contamination at the Company's current or former facilities; or at off-site locations where waste has been sent for disposal, regardless of fault or whether the Company, its predecessors or others are responsible for such contamination. The Company has been responsible for remediation of contamination at some of the Company's locations, and while such costs have not been material to date, the cost of remediation of any of these and any newly-discovered contamination cannot be quantified, and the Company cannot assure you that it will not materially affect the Company's profits or cash flows. Changes in laws, regulations or enforcement policies, including without limitation new or additional regulations

affecting disposal of hazardous substances and waste, greenhouse gas emissions or use of fossil fuels, could have a material adverse effect on the Company's business, financial condition, or results of operations.
The Company is subject to certain additional regulations as a United States government contractor or subcontractor.
Some of the Company's revenue is derived from contracts with agencies of the United States government and subcontracts with its prime contractors. As a United States government contractor or subcontractor, the Company is subject to federal contracting regulations, including the Federal Acquisition Regulations, which govern the allowability of costs incurred by the Company in the performance of United States government contracts. In connection with the Company's United States government business, the Company is also subject to government audits and to review and approval of the Company's policies, procedures, and internal controls for compliance with procurement regulations and applicable laws. In certain circumstances, if the Company does not comply with the terms of a government contract or with regulations or statutes, the Company could be subject to downward contract price adjustments or refund obligations or could in extreme circumstances be assessed civil and criminal penalties or be debarred or suspended from obtaining future contracts for a specified period of time.

PART II

Item 5. | Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Company’s common stock is traded on the NASDAQ Global Select Market (“NASDAQ”) under the symbol “ROCK.”
As of February 21, 2023, there were approximately 32 shareholders of record of the Company’s common stock. However, the Company believes that it has a significantly higher number of beneficial owners because of the number of shares that are held by banks, brokers, and other financial institutions.
The Company did not declare any cash dividends during the years ended December 31, 2022 and 2021 and does not expect to pay any in the foreseeable future. The Company intends to use cash generated by operations to reinvest in the businesses, fund acquisitions and to repurchase stock.

Company Overview
The Company is a leading manufacturer and provider of products and services for the renewable energy, residential, agtech, and infrastructure markets. The Company serves customers primarily in North America including renewable energy (solar) developers, institutional and commercial growers of food and plants, home improvement retailers, wholesalers, distributors, and contractors. The Company's operational infrastructure provides the necessary scale to support local, regional, and national customers in each of its markets.
The Company operates and reports its results in the following four reporting segments:
•Renewables
•Residential
•Agtech
•Infrastructure
Demand for products and services in the segments and end markets the Company's businesses serve are subject to economic conditions that are influenced by various factors. These factors include but are not limited to changes in general economic conditions, interest rates, exchange rates, commodity costs, expiration of solar rebates, supply limitations that impact the availability of solar panels and therefore solar racking installations, demand for residential construction, demand for repair and remodeling, governmental policies and funding, tax policies and incentives, tariffs, trade policies, weather patterns, the level of non-residential construction and infrastructure projects, the need for protection of high value assets, demand for renewable energy sources, and climate change. The Company believes the key elements of its strategy outlined in Item 1. Business of this Annual Report on Form 10-K will allow the Company to respond timely to these factors.
Recent Trends
The broader market dynamics over the past two years, which has included the residual impact of COVID-19, have resulted in impacts to the Company, including material cost inflation, labor availability issues and logistics costs increases. The Company has also been impacted from supply constraints for materials and commodities used in its operations and from solar panels shortages used by the Company's customers in conjunction with the goods and services the Company provides. In certain instances these constraints have resulted in project delays, cost inflation and logistical delays. The Company continues to work with its customers and suppliers in this dynamic environment to better align pricing, understand the existing and potential future impacts to the supply chain, and make efforts to mitigate such impacts. While certain of these pressures have subsided over the latter part of 2022, the Company expects that some of these dynamics will continue into 2023 and could continue to have an impact on demand, material costs, labor and logistics.
In early 2022, the U.S. Department of Commerce ("USDOC") was petitioned to investigate alleged circumvention of anti-dumping and countervailing duties on Chinese imports of solar panels produced in other countries in Southeast Asia. In March 2022, the USDOC announced that it would investigate the circumvention alleged in the petition. In June 2022, the President of the United States issued an Executive Order to suspend any tariffs that result from this investigation for two years. In December 2022, the USDOC issued a preliminary report that identified occurrences of the alleged circumvention against specific solar panel manufacturers, but also cleared other manufacturers. No retroactive tariffs or penalties are expected against the former group. The original complainant is expected to appeal these USDOC findings and decisions, including pursuit of a temporary restraining order.
In June 2022, the Uyghur Forced Labor Prevention Act ("UFLPA") was enacted. The UFLPA requires traceability of components of imported goods to validate that the components are not sourced from areas in the Xinjiang region of China. There are reports that solar panels continue to be held at U.S. customs until the importer is able to prove where they have been sourced. It is the Company's understanding that these panels are starting to be released by U.S. customs, however, progress is slow and a significant backlog of panels continue to await review and release..
As the timing and progress of many of the Company's customers’ projects depend upon the supply of solar panels, the Company's operating results have been and could be further impacted by these actions. The Company continues to work with customers who are assessing their ability to source panels needed to complete projects.
On August 16, 2022, the Inflation Reduction Act ("IRA") was signed into law. Among other things, the IRA provides for Investment Tax Credits ("ITC") for renewable energy. The IRA provides a 30% ITC for projects started prior to the guidance issued by the Department of the Treasury and published in the Federal Register on November 30, 2022,

Table of Co n tents
regarding new wage and apprenticeship standards. Sixty days after the issuance of such guidance, January 29, 2023, the base ITC will be 6%, with an additional 24% available if the new labor standards are met or the project is less than one megawatt. The IRA also provides the option to earn an additional 10% credit for domestic content, and separately, an additional 10% credit for siting a project in an “energy community.” Lastly, there are Manufacturers Tax Credits available to suppliers of certain, specific solar tracker components, including mechanical parts and battery storage, that are made in the U.S. The Company expects the ITC to accrue to its downstream customers, solar investors, and expect Manufacturers Tax Credits to accrue to the Company's upstream suppliers. The Company anticipates that these tax credits will provide stability for the industry and should reduce policy driven demand swings for the Company's products. As provided for in the issued guidance relative to prevailing wage and sourcing provisions, the Company intends to work with its customers to maximize the tax credits available to them.
The Company enters 2023 with solid operating momentum and a plan to deliver full year growth, margin expansion, and strong cash performance for the year, as it anticipates 2023 will continue to be a fluid external environment as the Residential market is expected to return to normal demand seasonality, panel supply for the solar industry is expected to improve in the second half of the year, and Agtech projects for produce growing are expected to be finalized.
Operating Performance Measures
The Company uses certain operating performance measures, specifically consolidated gross margin, operating margin by segment and consolidated operating margin, to manage its businesses, set operational goals, and establish performance targets for incentive compensation for its employees. The Company defines consolidated gross margin as a percentage of total consolidated gross profit to total consolidated net sales. The Company defines operating margin by segment as a percentage of total income from operations by segment to total net sales by segment and consolidated operating margin as a percentage of total consolidated income from operations to total consolidated net sales. The Company believes gross margin and operating margin may be useful to investors in evaluating the profitability of its segments and the Company on a consolidated basis.

Consolidated net sales increased from 2021 by $50.2 million, or 3.7%, to $1.4 billion for 2022 compared to 2021. The 3.7% increase in revenue was driven by a 2.7% or $36.2 million increase from organic revenue, the result of an 11% increase in pricing to customers partially offset by a net volume decline of 10%, and a 2.0% or $26.4 million increase generated from the current year acquisition of QAP in the Residential segment. Partially offsetting these increases was a decline of 0.9% or $12.5 million from the Company's processing business which was reclassified as held-for-sale as of March 31, 2022; the results of which will continue to be reported in the Company's consolidated operating results from continuing operations until the sale of the business is completed.
The organic revenue growth in the Residential segment, largely driven by price management and participation gains, and the Infrastructure segment revenue growth more than offset volume declines in both the Renewables and Agtech segments, which were primarily impacted by project delays. Consolidated backlog decreased 12% to $301 million down from $344 million at the end of the prior year.
Net sales in the Renewables segment decreased 12.6%, or $54.5 million, to $377.6 million in 2022 compared to $432.1 million in 2021. Revenue decreased by 12.6% from the prior year as the market demand for solar panel installation continues to be impacted by the UFLPA, which was implemented in June 2022, along with the impact of the Department of Commerce's preliminary ruling on its solar panel AD/CVD anti-circumvention investigation, which has impacted scheduling of projects. As a result, backlog decreased 17% from the prior year for this segment, however, given the current conversations with the Company's customers and expected continued progress on the part of panel importers, the Company expects backlog to improve once there is better understanding of documentary compliance requirements relative to the UFLPA.
Net sales in the Residential segment increased 20.7%, or $131.7 million, to $767.2 million in 2022 compared to $635.5 million in 2021. T he increase from the prior year was the result of continued pricing actions to better align price to inputs costs resulting from inflation, along with participation gains and strong market demand. Sales generated by QAP, acquired in the third quarter of 2022, also contributed $26.4 million to the increase in the current year.
Net sales in the Agtech segment decreased 15.2%, or $30.3 million, to $168.9 million in 2022 compared to $199.2 million in 2021. Excluding the impact of the processing equipment business which has been classified as held-for-sale as of March 31, 2022, revenue declined $17.8 million due to project delays in the Company's produce and cannabis businesses, the result of continued rescheduling and re-scoping of projects. Partially offsetting the decrease was growth in the Company's commercial greenhouse business. While quote activity remains robust, order backlog was also impacted by continued rescheduling and re-scoping of projects and decreased 13% year over year.
Net sales in the Infrastructure segment increased 4.5%, or $3.3 million, to $76.3 million in 2022 compared to $73.0 million in 2021. The increase in revenue was driven by growth in demand for fabricated products. Strong bidding activity resulted in a 23% increase in backlog from the prior year. Management expects continued positive impact from the increased infrastructure spending related to the Infrastructure Investment and Jobs Acts in 2023.
The Company's consolidated gross margin increased to 22.9% for 2022 compared to 21.6% for 2021. This increase was primarily the result of favorable price/cost management along with favorable product and service revenue mix, along with improved operating execution from 80/20 and lean enterprise initiatives and participation

gains in the Residential segment. These actions more than offset the impacts of supply chain challenges and severe weather which the Company experienced in the early part of 2022, that resulted in increased costs due to disruptions in project timing in the Renewables and Agtech segments.
Selling, general, and administrative ("SG&A") expenses increased by $3.9 million, or 2.1%, to $188.6 million for 2022 from $184.7 million for 2021. The $3.9 million increase was primarily due to incremental SG&A expenses recorded for the recent acquisition of QAP along with higher expenses associated with investments in the Company's organization to drive performance, including investing in the Company's ERP systems to simplify and digitize its businesses. This increase was partially offset by lower performance-based compensation expense for equity-based awards in the Company's deferred compensation plan that are valued based on its 200-day average stock price, as compared to the prior year. Despite the above increases, SG&A expenses as a percentage of net sales decreased to 13.5% for 2022 compared to 13.8% for 2021.
During 2021, the Company recognized intangible asset impairment charges of $8.3 million. The impairment was the result of a rebranding initiative in 2021 that resulted in the discontinuation of certain indefinite-lived trademarks in the Agtech segment.
The following table sets forth the Company’s income from operations and income from operations as a percentage of net sales by reportable segment for the years ended December 31 (in thousands):

The Renewables segment generated an operating margin of 6.7% in 2022 compared to 4.7% in 2021. The increase in operating margin was the combined result of costs incurred in the prior year related to backlog amortization and integration costs from recent acquisitions not recurring in 2022. Improved project management along with favorable alignment of material costs to customer selling prices and field operations efficiencies beginning in May and sustained through to the end of 2022 also contributed to the increase.
The Residential segment operating margin slightly decreased to 16.5% in 2022 from 16.7% in 2021. The decrease in operating margin was the result of the expected lower margins generated by QAP as the Company continues to integrate them operationally, partially offset by the benefit of improved alignment of price actions and input costs, along with continued solid execution resulting from 80/20 productivity initiatives.
The Agtech segment generated an operating margin of 1.7% in 2022 compared to (0.5)% in 2021. Excluding the impact of both a prior year $8.3 million impairment charge for an indefinite lived trademark that was discontinued as a result of a rebranding initiative in 2021, and the impact of the Processing business which has been classified as held for sale as of March 31, 2022, operating margin for the current year was essentially flat as compared to the prior year.
The Infrastructure segment operating margin decreased to 11.8% in 2022 compared to 12.2% in 2021. The margin declined from the prior year due to the impact of plate steel inflation on fixed price contracts in the earlier part of the year largely offset by improving operating execution.
Unallocated corporate expenses decreased $3.5 million, or 9.3%, for 2022 from $37.0 million for 2021 to $33.5 million for 2022. The decrease in expense was largely the result of lower performance-based compensation

expense related to equity-based awards in the Company's deferred compensation plan that are valued based on its 200-day average stock price as compared to the prior year.
Interest expense increased $2.4 million to $4.0 million for 2022 from $1.6 million for 2021. The increase in expense was primarily due to higher outstanding balances on the Company's revolving credit facility during the current year along with higher interest rates compared to the prior year. The outstanding balances on the Company's revolving credit facility were $91.0 million and $23.8 million as of December 31, 2022, and 2021, respectively.
The Company recorded other expense of $14.6 million in 2022, compared to other income of $4.2 million in 2021. In 2022, the Company recorded a $14.0 valuation allowance related to the write-down of the processing business to estimated fair market value, which has been classified as held-for-sale as of March 31, 2022. In 2021, the Company recognized a $4.7 million gain on the sale of securities received from the sellers of Thermo Energy Systems, Inc. to settle indemnification claims recorded in the prior year.
The Company recognized a provision for income taxes of $29.1 million, an effective tax rate of 26.1%, for 2022 compared with a provision for income taxes of $25.0 million, an effective tax rate of 25.2%, for 2021. The effective tax rates for 2022 and 2021 exceeded the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences partially offset by an excess tax benefit on stock-based compensation.
Liquidity and Capital Resources
The following table sets forth the Company's liquidity position as of:

(in thousands) |  | December 31, 2022 |  | December 31, 2021
Cash and cash equivalents |  | $ | 17,608 |  |  | $ | 12,849 |
Availability on revolving credit facility |  | 304,505 |  |  | 369,305 |
|  | $ | 322,113 |  |  | $ | 382,154 |

Sources of Liquidity
The Company's sources of liquidity are comprised of cash on hand and available borrowing capacity provided under the Company's Credit Agreement (the "Credit Agreement"), entered into on December 8, 2022. This Credit Agreement replaced and paid off all amounts owed under the Sixth Amended and Restated Credit Agreement dated as of January 24, 2019. The Credit Agreement maintains similar capacity as the prior agreement in which it provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million. The Company can request additional financing to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Credit Agreement. The Company believes that these sources provide the Company with ample liquidity and capital resources to invest in operational excellence, growth initiatives and the development of the organization.
The Company has been able to weather the economic impacts of the broader market dynamics, including the inflationary cost environment, while continuing to make investments that support the Company's strategy. The Company continues to remain focused on managing its working capital, closely monitoring customer credit and collection activities, and working to extend payment terms with its vendors. The Company believes its liquidity, together with the cash expected to be generated from operations, should be sufficient to fund working capital needs and growth initiatives for the foreseeable future.
The Company uses the Credit Agreement to provide liquidity and capital resources primarily for the Company's U.S. operations. Generally, the Company's foreign operations have generated cash flow from operations sufficient to invest in working capital and fund their capital improvements. As of December 31, 2022 and 2021, the Company's foreign subsidiaries held $15.2 million and $11.3 million of cash, respectively.
Outstanding balances on the Company's revolving credit facility under the Company's Credit Agreement accrue interest at a rate, at the Company's option, equal to the applicable margin plus (a) a base rate, (b) a daily simple secured overnight financing rate ("SOFR"), (c) a term SOFR rate, or (d) for certain foreign currencies, a foreign currency rate. See Note 9 to the Company's consolidated financial statements in Part II, Item 8, Financial Statements, of this Annual Report on Form 10-K for further information on the Company’s Credit Agreement.

Uses of Cash / Cash Requirements
The Company's material short-term cash requirements primarily include accounts payable, certain employee and retiree benefit-related obligations, operating lease obligations, interest payments on outstanding debt, repayments of borrowing on its revolving credit facility, capital expenditures, and other purchase obligations originating in the normal course of business for inventory purchase orders and contractual service agreements. The Company's principal capital requirements are to fund its operations' working capital and capital improvements, as well as provide capital for acquisitions and to strategically allocate capital through repurchases of Company stock. The Company will continue to invest in growth opportunities as appropriate while focusing on working capital efficiency and profit improvement opportunities to minimize the cash invested to operate its business. The Company intends to fund its cash requirements through cash generated from operations and, as necessary, from the availability on its revolving credit facility. See Notes 8, 10, 12, 18 and 20 to the Company's consolidated financial statements in Part II, Item 8, Financial Statements, of this Annual Report on Form 10-K for further detail on the Company's accrued expenses, employee and retiree benefit-related obligations, operating lease obligations and historical capital expenditures.
In May 2022, the Company's Board of Directors authorized a share repurchase program of up to $200 million of the Company's issued and outstanding common stock. The program has a duration of three years, ending May 2, 2025. Repurchases may be made, from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions, applicable legal requirements, debt covenants and other considerations. Any such repurchases may be executed using open market purchases, privately negotiated agreements or other transactions. The repurchase program may be suspended or discontinued at any time at the Company's discretion. As of December 31, 2022, the Company has repurchased 1,997,366 shares for an aggregate price of $85.9 million under this repurchase program.
During 2020, the Company opted to defer remittance of the employer portion of Social Security tax as provided in the Coronavirus, Aid, Relief and Economic Security Act ("CARES Act"), which allowed the Company to retain $4.4 million in cash during 2020 that would have otherwise been remitted to the federal government. The deferred tax payments were required to be repaid in two installments occurring near the end of each year 2021 and 2022, of which $1.9 million was repaid in 2021 and the remaining $2.5 million was repaid in 2022.
Over the long-term, the Company expects that future investments, including strategic business opportunities such as acquisitions, may be financed through a number of sources, including internally available cash, availability under the Credit Agreement, new debt financing, the issuance of equity securities, or any combination of the aforementioned. The $52.1 million preliminary purchase price for the acquisition of QAP was financed primarily through borrowing on the Company's revolving credit facility. Additional cash payments may be required for customary adjustments as provided for in the membership interest purchase agreement. All potential acquisitions are evaluated based on the Company's acquisition strategy, which includes the enhancement of the Company's existing products, operations, and/or capabilities, as well as expanding the Company's access to new products, markets, and customers, with the goal of creating compounding and sustainable stockholder value.
These expectations are forward-looking statements based upon currently available information and may change if conditions in the credit and equity markets deteriorate or other circumstances change. To the extent that operating cash flows are lower than current levels, or sources of financing are not available or not available at acceptable terms, the Company's future liquidity may be adversely affected.

Operating Activities
Net cash provided by operating activities of continuing operations for 2022 of $102.7 million consisted of income from continuing operations of $82.4 million, non-cash net charges totaling $58.6 million, which include depreciation, amortization, stock compensation, held for sale valuation allowance, provision for deferred income taxes and other non-cash charges, offset by a net investment in working capital and other net assets of $38.3 million. The net investment in working capital was largely the result of the timing and the settlement of payables in the current year related to inventory received in the prior year. Further, offsetting the impact of the decline in payables, the Company also reduced its investment in inventory as supply chain challenges subsided in the current year and the Company was able to better align inventory levels with lower sales volumes. The decrease in accounts receivable as a result of lower sales volume in the fourth quarter of 2022 compared to the fourth quarter of 2021 also partially offset the investment in working capital.
Net cash provided by operating activities of continuing operations for 2021 of $25.1 million consisted of income from continuing operations of $74.5 million, non-cash net charges totaling $54.6 million, which include depreciation, amortization, intangible asset impairment, stock compensation, and other non-cash charges, offset by a net investment in working capital and other net assets of $104.0 million. The investment in working capital and other net assets was largely due to increases in inventory and accounts payable due to higher inventory input costs, such as raw materials and freight, and provisioning for potential supply chain disruptions, along with increases in accounts receivable due to the timing of invoicing project-based customers, partially offset by a decrease in accrued expenses.
Investing Activities
Net cash used in investing activities of continuing operations for 2022 of $71.7 million consisted of net cash paid of $51.6 million for the acquisition of Quality Aluminum Products in the third quarter of 2022 and capital expenditures of $20.1 million.
Net cash provided by investing activities of continuing operations for 2021 of $24.7 million consisted of net proceeds of $38.1 million from the sale of the Company's Industrial business in the first quarter of 2021, $4.1 million from the receipt of a final working capital settlement from the prior year acquisition of TerraSmart, and proceeds of $0.2 million from the sale of property and equipment, offset by capital expenditures of $17.7 million.
Financing Activities
Net cash used in financing activities for 2022 of $25.0 million consisted of $89.5 million of common stock repurchases, $2.0 million payment of debt issuance costs, offset by net proceeds from borrowings of $66.5 million. Shares repurchases of 1,997,366 shares repurchased under the Company's authorized share repurchase program totaled $85.1 million with the balance repurchased of $4.4 million of common stock repurchases related to the net settlement of tax obligations for participants in the Company's equity incentive plans. Net proceeds from borrowings consisted of $204.5 million in proceeds from borrowing on the Company's long-term credit facility, offset by $138.0 million in payments on long-term debt.
Net cash used in financing activities for 2021 of $66.6 million consisted of $120.6 million in payments on long-term debt and $6.5 million of common stock repurchases related to the net settlement of tax obligations for participants in the Company's equity incentive plans, offset by $59.5 million in proceeds from borrowing on the Company's long-term credit facility and $1.0 million from the issuance of common stock from stock option exercises during the year.
Critical Accounting Estimates
The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make decisions based upon estimates, assumptions, and factors it considers relevant to the circumstances. Such decisions include the selection of applicable principles and the use of judgment in their application, the results of which could differ from those anticipated.
A summary of the Company’s significant accounting policies are described in Note 1 of the Company’s consolidated financial statements included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
30

Table of Co n tents
Our most critical accounting estimates that require the most difficult, subjective and complex judgments include:
•revenue recognition on contracts with customers;
•the estimation of fair value for acquired assets and liabilities assumed in business combination transactions; and
•the assessment of recoverability of goodwill and other indefinite-lived intangible assets.
Management reviews these estimates on a regular basis and makes adjustments based on historical experience, current conditions, and future expectations. Management believes these estimates are reasonable, but actual results could differ from these estimates.
Revenue Recognition on Contracts with Customers
The vast majority of the Company's sales contracts are for standard products with revenue recognized at the point in time the Company transfer control to the customer. The point in time the Company transfers control is based on when the Company determines the customer has legal title, significant risks and rewards of ownership of the asset, and the Company has a present right to payment for the product. However, revenue representing 40%, 47% and 40% of the Company's 2022, 2021 and 2020 consolidated net sales, respectively, was recognized over time under the cost-to-cost method as the Company satisfied its performance obligations. This method of revenue recognition pertains to activities within the Renewables, Agtech, and Infrastructure segments.
Revenue recognized on contracts over time using the cost-to-cost method for measuring progress is recognized as work progresses toward completion based on the ratio of cumulative costs incurred to date to estimated total contract costs at completion. Revenues are recognized proportionally as costs are incurred under this method. Estimates of the total costs at completion for the performance obligations involve subjective judgment and estimation to determine total costs expected to be incurred by the time the performance obligation has been completed and accepted by the customer. The estimates of total costs to be incurred at completion of each contract are sensitive to significant judgments and assumptions, such as the expected costs to complete installation, which are affected by customer site-specific conditions as well as availability and cost of third-party contractors to complete the installation process. These estimates, judgments and assumptions impact the timing and amount of net sales and cost of sales recognized on in-progress performance obligations with customers. The Company continuously review its estimates and the progress and performance of the performance obligation for substantially all contracts that the Company recognizes revenue over time under the cost-to-cost method. Any adjustments or changes in these estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. A significant change in an estimate on one or more contracts could have a material effect on the Company's results of operations.
Contract costs include all direct costs related to contract performance. Selling and administrative expenses are charged to operations as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Because of inherent uncertainties in estimating costs, it is reasonably possible that changes in performance could result in revisions to cost and revenue, which are recognized in the period when the revisions are determined.
Accounting for Acquired Assets and Liabilities Assumed in a Business Combination
When the Company acquires a business, the Company allocates the purchase price to the assets acquired and liabilities assumed in the transaction at their respective estimated fair values. The Company records any premium over the fair value of net assets acquired as goodwill. Significant judgment is necessary to determine the fair value of the purchase price. The allocation of the purchase price involves judgments and estimates both in characterizing the assets and in determining their fair value. The way the Company characterizes the assets has important implications, as long-lived assets with definitive lives, for example, are depreciated or amortized, whereas goodwill is tested annually for impairment, as explained above.
With respect to determining the fair value of assets, the most subjective estimates involve valuations of long-lived assets, such as identified intangible assets and property, plant, and equipment. The Company uses all available information to make these fair value determinations and engage independent valuation specialists to assist in the fair value determination of the acquired long-lived assets. The fair values of long-lived assets are determined using valuation techniques that use discounted cash flow methods, independent market appraisals, and other acceptable valuation techniques. The significant assumptions used to estimate the value of the intangible assets included discount rates, customer attrition, and certain assumptions that form the basis of the forecasted results (e.g.,
31

Table of Co n tents
revenue growth rates and operating profit margin). The significant assumptions related to estimating the fair value of the intangible assets above are forward looking and could be affected by future economic market conditions.
Goodwill and Other Indefinite-lived Intangible Asset Impairment Testing
The Company's goodwill and indefinite-lived intangible asset balances of $512.4 million and $55.5 million, respectively, which in aggregate represent 46% of total assets as of December 31, 2022, are subject to impairment testing. The Company test goodwill and indefinite-lived intangible assets for impairment on an annual basis as of October 31 and at interim dates when indicators of impairment are present. Indicators of impairment could include a significant long-term adverse change in business climate, poor indicators of operating performance, or a sale or disposition of a significant portion of a reporting unit.
The Company test goodwill for impairment at the reporting unit level. The Company identifies the Company's reporting units by assessing whether the components of the Company constitute businesses for which discrete financial information is available and segment management regularly reviews the operating results of those components. The Company has eight reporting units, all of which have goodwill. The Company test its indefinite-lived intangible assets for impairment by comparing the fair value of the indefinite-lived intangible asset, determined using a discounted cash flow model, with its carrying amount.
During interim periods, the Company evaluates the potential for goodwill and indefinite-lived intangible asset impairment using a qualitative assessment by considering factors such as, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for the Company's products and services, regulatory and political developments, entity specific factors such as strategy, changes in key personnel, and overall financial performance. Upon completing this assessment, if it is determined that it is more likely than not that the fair value is less than its carrying value, the Company proceeds to a quantitative impairment test. During the interim periods of 2022, the Company concluded that no indicators of impairment existed at interim dates and did not perform any quantitative interim impairment tests related to goodwill and indefinite-lived intangible assets.
The Company conducts its annual impairment test on all eight reporting units as of October 31, during which the Company test goodwill and other indefinite-lived intangible assets for impairment. On an annual basis, the quantitative goodwill impairment test consists of comparing the fair value of a reporting unit with the carrying amount of the reporting unit including goodwill. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, an impairment loss is recognized in the amount by which the carrying value of the reporting unit exceeds the fair value of the reporting unit. The assumptions used to determine the fair value of the Company's indefinite-lived intangible assets are consistent with the assumptions employed in the determination of the fair values of the Company's reporting units. An impairment loss would be recognized for the carrying amount in excess of its fair value. The fair values of the impaired trademarks were determined using an income approach consisting of the relief-from-royalty method.
The annual quantitative impairment tests require subjective and complex judgment due to the significant estimation required in determining the fair value of the reporting units and the fair value of indefinite-lived intangible assets. Reporting unit fair value estimates include significant assumptions such as: revenue growth rates, operating margins, estimated royalty rates, company-specific risk premiums used in the weighted-average cost of capital, and EBITDA multiples, which are affected by expectations about future market or economic conditions. The Company performs sensitivity analyses on significant assumptions to evaluate how changes in the estimated fair values of reporting units and indefinite-lived intangible assets respond to changes in assumptions, specifically the revenue growth rates and the weighted-average cost of capital.
As a result of the Company's quantitative testing, none of the reporting units as of the Company's testing date had carrying values in excess of their fair values, nor were any of the reporting units "at-risk" of impairment. The Company quantitatively defines "at risk" as a percentage of the excess of the reporting unit's fair value over its carrying amount that is less than 10%. An "at risk" reporting unit qualitatively represents a reporting unit with a higher degree of uncertainty of the reporting unit's ability to meet its forecasted cash flows based upon revenue growth rate and operating margin assumptions relied upon in the estimation of its fair value.
There were no impairment charges against goodwill recorded during the years ended December 31, 2022, 2021, and 2020.
32

Table of Co n tents
The Company did not recognize any impairment charges on its indefinite-lived intangible assets in 2022 and 2020. During 2021, the Company recognized $8.3 million of impairment charges on its indefinite-lived intangible assets, due to a rebranding initiative resulting in the discontinuation of two indefinite-lived trademarks in the Agtech segment.
Recent Accounting Pronouncements
New accounting pronouncements are issued periodically that affect the Company's current and future operations. See Note 1 to the Company's consolidated financial statements in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K for further information on recent accounting pronouncements in accordance with U.S. generally accepted accounting principles.

Item 7A. | Quantitative and Qualitative Disclosures about Market Risk

In the ordinary course of business, the Company is exposed to various market risk factors, including changes in general economic conditions, competition, and raw materials pricing and availability. In addition, the Company is exposed to other financial market risks, primarily related to its long-term debt and foreign operations.
Raw Material Pricing Risk
The Company is subject to market risk exposure related to volatility in the price of the Company's principal raw materials of steel, aluminum and resins, which are cyclical in nature and have been historically volatile. Exposure to commodity price fluctuations are generally managed through alignment of the Company's materials costs with pricing to customers by passing increases in raw material costs through to customers and maintaining inventory levels not in excess of the Company's production requirements. The Company may experience unfavorable cost-price alignment if increases in these raw material costs cannot be partially or fully passed on to customers, or if the timing of price increases lags behind the raw material cost increases. The Company cannot accurately calculate the pre-tax impact a one percent change in the commodity costs would have on the Company's 2022 operating results as the change in commodity costs would both impact the cost to purchase materials and the selling prices the Company offers to customers. The impact to the Company's operating results would significantly depend on the competitive environment and the costs of other alternative products, which could impact the Company's ability to pass commodity costs to customers.
Interest Rate Risk
The Company currently utilizes variable interest rate debt to manage interest rate risk, and would consider utilizing fixed rate debt if borrowings were expected to be outstanding for an extended period of time. In order to manage interest rate risk, the Company will continue to monitor changes in its debt levels and access to capital ensuring interest rate risk is appropriately managed. At December 31, 2022, the Company's available variable rate debt consisted of borrowings under the Company's Credit Agreement, of which $91 million was outstanding on the revolving credit facility as of December 31, 2022 and was the only debt outstanding at year end. Effective December 8, 2022, borrowings under the revolving credit facility bore interest at a variable interest rate based upon, at the Company's option, at a rate equal to an additional margin plus (a) a base rate, (b) a daily simple SOFR rate, (c) a term SOFR rate or (d) for certain foreign currencies, a foreign current rate. Prior to December 8, 2022, borrowings under the revolving credit facility under the Company's Sixth Amended and Restated Credit Agreement bore interest at a variable interest rate based upon the LIBOR plus an additional margin. A hypothetical 1% increase or decrease in interest rates would have changed the Company's 2022 interest expense by $0.8 million.
Foreign Exchange Risk
The Company has foreign exchange risk due to the Company's international operations, primarily in Canada and Asia, and through sales to and purchases from foreign customers and vendors. Changes in the values of currencies of foreign countries affect the Company's financial position and cash flows when translated into U.S. dollars. The Company principally manages its exposures to many of these foreign exchange rate risks solely through management of its core business activities. The Company cannot accurately calculate the pre-tax impact that a one percent change in the exchange rates of foreign currencies would have on the Company's 2022 operating results as the changes in exchange rates would impact the cost of materials, the U.S. dollar revenue equivalents, and potentially the prices offered to overseas customers.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors of Gibraltar Industries, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Gibraltar Industries, Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 22, 2023 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

|  | Revenue Recognition on Contracts
Description of the Matter |  | During the year ended December 31, 2022, the amount of revenue recognized over time was $555 million. As discussed in Note 1 to the consolidated financial statements, the Company’s revenue on contracts is accounted for based on the cost-to-cost input measure of progress, whereby the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Auditing management’s estimates to complete for certain components is especially subjective due to significant judgment required in estimating the remaining costs to complete. Factors inherent in the estimation process include direct labor hours, direct material costs, and other direct costs. Due to uncertainties attributed to such factors, a significant change in an estimate on one or more contracts could have a material effect on the Company’s results of operations.
How We Addressed the Matter in Our Audit |  | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls that address the risks of material misstatement relating to the measurement and valuation of the Company’s review of estimated costs to complete, including the determination of the underlying significant assumptions and the completeness and accuracy of the open contracts reviewed. For example, we tested controls over management’s quarterly review of the cost estimates, monthly review of open contracts and completed contracts, and review over the cost estimates used to develop initial cost estimates on projects. To test the amount of revenue recognized from contracts, our audit procedures included, among others, assessing whether the performance obligations identified were appropriately recognized on an over time basis through inspection of the contract and inquiry from program management regarding the nature and scope of work and testing the completeness and accuracy of the data underlying the determination of the amount of revenue recognized in the current period. To assess the over time revenue recognition, we tested that the actual costs incurred on the project are complete and accurate through agreement to supporting evidence. Our testing of the assumptions included a combination of confirmation of contract terms, billings, and project status directly with customers, inquiries of the program management and financial personnel, inspection of evidence to support future estimated costs, performance of an analysis of actual gross margin on completed contracts compared to prior estimates, evaluation of subsequent year-end expenses incurred on projects, and assessment of the historical accuracy of management’s estimates by analyzing changes in project gross margins during project lifecycles and determining if those changes were driven by cost factors that should have been known or could have been reasonably estimated at project inception.

GIBRALTAR INDUSTRIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of consolidation
The consolidated financial statements include the accounts of Gibraltar Industries, Inc. and subsidiaries (the "Company"). All intercompany accounts and transactions have been eliminated in consolidation.
Use of estimates
The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates due to uncertainty in the current economic environment.
Segment Reporting
The Company has four reportable segments: Renewables, Residential, Agtech and Infrastructure. In 2021, the Company's former Renewable Energy and Conservation segment was divided into two segments, Renewables and Agtech. For further disclosure regarding the Company's reportable segments, refer to Note 20 "Segment Information."
Revenue recognition
Revenue is recognized when, or as, the Company transfers control of promised products or services to a customer in an amount that reflects the consideration the Company expects to be entitled in exchange for transferring those products or services.
Performance obligations satisfied at a point in time and significant judgments
Revenue from contracts with customers is recognized when the Company transfers control of the promised product at a point in time, which is determined when the customer has legal title and the significant risks and rewards of ownership of the asset, and the Company has a present right to payment for the product. The Company allocates the transaction price, which is generally the quoted price per terms of the contract and the consideration the Company expects to receive, to each performance obligation. These products are generally sold with rights of return and these contracts may provide other credits or incentives, which are accounted for as variable consideration. Sales returns, allowances, and customer incentives, including rebates, are treated as reductions to the sales transaction price and based largely on an assessment of all information (i.e., historical, current and forecasted) that is reasonably available to the Company, and estimated at contract inception and updated at the end of each reporting period as additional information becomes available.
Performance obligations satisfied over time and significant judgments
For a contract to construct an asset that the customer controls as it is being created or enhanced, or a promise to provide a product that has no alternative use to the Company and the Company has enforceable rights to payment, the Company recognizes revenue over time. For the contracts to construct a certain asset, the Company determines that the customer controls the asset while it is being constructed. For the contracts for products that have no alternative use and for which the Company has an enforceable right to payment, the Company identifies these products as products that are not a standard inventory item or the Company cannot readily direct the product to another customer for use without incurring a significant economic loss, or significant costs to rework the product.
The Company determines the transaction price for each contract based on the consideration the Company expects to receive for the promised products and services under the entire contract, which is generally the stated contract price based on an expected cost plus a margin.
For the above contracts with customers with respect to which the Company satisfies a performance obligation over time, the Company recognizes revenue based on the extent of progress towards completion of the performance obligation using the cost-to-cost measure of progress. Under the cost-to-cost measure of progress, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recognized proportionally as costs are incurred. Costs to fulfill a contract include all direct costs related to contract performance. Selling and administrative expenses are

Table of Co n tents
charged to operations as incurred. Provision for loss on an uncompleted performance obligation is recognized in the period in which such loss is determined.
The Company regularly reviews the progress under the cost-to-cost method and any adjustments are recognized as necessary. Changes in estimates are recognized as they become known using the cumulative catch-up basis.
The Company also recognizes revenues from services contracts over time. The Company recognizes revenue over time during the term of the agreement as the customer is simultaneously receiving and consuming the benefits provided throughout the Company's performance. Therefore, due to control transferring over time, the Company recognizes revenue on a straight-line basis throughout the contract period.
Contract assets and contract liabilities
Contract assets primarily represents revenue recognized for performance obligations that have been satisfied but for which amounts receivable have not been billed. These are included as current assets and included within accounts receivable on the Company's consolidated balance sheets. Contract liabilities include payments received from customers in advance of the satisfaction of performance obligations for a contract. The Company does not consider contract advances to be significant financing components as the intent of these payments in advance are for reasons other than providing a significant financing benefit and are customary in the Company's industry. Unearned revenue relates to payments received in advance of performance under the contract and is recognized when the Company performs under the contract. Unearned revenue is presented within accrued expenses in the Company's consolidated balance sheets.
Costs to obtain a contract with a customer
The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. If the amortization period of the asset is one year or less, the Company recognizes the incremental costs of obtaining a contract as an expense when incurred. These incremental costs include, but are not limited to, sales commissions incurred to obtain a contract with a customer.
Cash and cash equivalents
All highly liquid investments with a maturity of three months or less are considered cash equivalents.
Accounts receivable and allowance for doubtful accounts and contract assets
Accounts receivable are composed of trade and contract receivables recorded at either the invoiced amount or costs in excess of billings, are expected to be collected within one year, and do not bear interest.
The Company’s expected loss allowance methodology for accounts receivable and costs in excess of billings (collectively "accounts receivable") is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers' accounts receivables. The Company is exposed to credit losses through sales of products and services. Due to the short-term nature of such accounts receivable, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. Additionally, specific allowance amounts are established to record the appropriate provision for customers that no longer share risk characteristics similar with other accounts receivable. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be u ncollectible after all means of collection have been exhausted and the potential for recovery is considered remote.
Estimates are used to determine the allowance. These estimates are based on assessment of anticipated payment and all other historical, current and future information that is reasonably available.

Concentrations of credit risk in accounts receivable are limited to those from significant customers that are believed to be financially sound. As of December 31, 2022 and 2021, the Company's most significant customer is a home improvement retailer. The home improvement retailer purchases from the Residential segment. Accounts receivable as a percentage of consolidated accounts receivable from the home improvement retailer was 14% as of December 31, 2022 and 2021. Net sales to the home improvement retailer as a percentage of consolidated net sales were 14%, 13%, and 14% during the years ended December 31, 2022, 2021 and 2020, respectively.
Inventories
Inventories are valued at the lower of cost, determined using the first-in, first-out method, or net realizable value. Shipping and handling costs are recognized as a component of cost of sales.
Property, plant, and equipment
Property, plant, and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Interest is capitalized in connection with construction of qualified assets. Expenditures that exceed an established dollar threshold and that extend the useful lives of assets are capitalized, while repair and maintenance costs are expensed as incurred. The estimated useful lives of land improvements, buildings, and building improvements are 15 to 40 years, while the estimated useful lives for machinery and equipment are 3 to 20 years.
The table below sets forth the depreciation expense recognized during the years ended December 31 (in thousands):

| 2022 |  | 2021 |  | 2020
Depreciation expense | $ | 14,583 |  |  | $ | 13,110 |  |  | $ | 11,252 |

Acquisition related assets and liabilities
Accounting for the acquisition of a business as a purchase transaction requires an allocation of the purchase price to the assets acquired and the liabilities assumed in the transaction at their respective estimated fair values. The most complex estimations of individual fair values are those involving long-lived assets, such as property, plant, and equipment and intangible assets. The Company uses all available information to make these fair value determinations and engages independent valuation specialists to assist in the fair value determination of the acquired long-lived assets.
Goodwill and other intangible assets
The Company tests goodwill for impairment at the reporting unit level on an annual basis at October 31, or more frequently if an event occurs, or circumstances change, that indicate that the fair value of a reporting unit could be below its carrying value. The reporting units are at the component level, or one level below the operating segment level. Goodwill is assigned to each reporting unit as of the date the reporting unit is acquired.
The Company may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for some or all of the Company's selected reporting units. If, after completing the assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company proceeds to a quantitative test. The Company may also elect to perform a quantitative test instead of a qualitative test for any or all of the Company's reporting units.
The quantitative impairment test consists of comparing the fair value of a reporting unit, determined using two valuation techniques, to its carrying value. If the carrying value of the reporting unit exceeds its fair value, goodwill is
44

Table of Co n tents
considered impaired, and a loss measured by the excess of the carrying value of the reporting unit over the fair value of the reporting unit must be recorded.
The Company also tests its indefinite-lived intangible assets for impairment on an annual basis as of October 31, or more frequently if an event occurs, or circumstances change, that indicate that the fair value of an indefinite-lived intangible asset could be below its carrying value. The impairment test consists of comparing the fair value of the indefinite-lived intangible asset, determined using discounted cash flows on a relief-from-royalty basis, with its carrying amount. An impairment loss would be recognized for the carrying amount in excess of its fair value. Acquired identifiable intangible assets are recorded at cost. Identifiable intangible assets with finite useful lives are amortized over their estimated useful lives. For additional disclosure of the Company's goodwill and other intangible assets refer to Note 7 "Goodwill and Related Intangible Assets."
Impairment of long-lived assets
Long-lived assets, including acquired identifiable intangible assets with finite useful lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. In specific situations, when the Company has selected individual assets to be sold or scrapped, the Company obtains market value data for those specific assets and measures and records the impairment loss based on such data. Otherwise, the Company uses undiscounted cash flows to determine whether impairment exists and measures any impairment loss by approximating fair value using acceptable valuation techniques, including discounted cash flow models and third-party appraisals. For additional disclosure on impairment of the Company's long-lived assets refer to Note 7 "Goodwill and Related Intangible Assets," Note 14 "Held for Sale and Discontinued Operations" and Note 15 "Exit Activity Costs and Asset Impairments."
Leases
The Company determines if an agreement is, or contains, a lease at the inception of the agreement. At lease commencement, the Company recognizes a right-of-use asset and a lease liability for leases with terms greater than twelve months. The initial lease liability is recognized at the present value of remaining lease payments over the lease term. Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheets. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups. Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.
Deferred charges
Deferred charges associated with initial costs incurred to enter into new debt arrangements are included as a component of long-term debt and are amortized as a part of interest expense over the terms of the associated debt agreements.
Advertising
The Company expenses advertising and marketing costs as incurred. For the years ended December 31, 2022, 2021 and 2020, advertising and marketing costs were $10.9 million, $8.0 million, and $7.2 million, respectively.
Foreign currency transactions and translation
The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at the rate of exchange in effect at the balance sheet date. Income and expense items are translated at the average exchange rates prevailing during the period.
Income taxes
The provision for income taxes is determined using the asset and liability approach. Under this approach, deferred income taxes represent the expected future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities. The Company records a valuation allowance to reduce deferred tax assets when uncertainty exists regarding their realization.

Equity-based compensation
The Company measures the cost of equity-based compensation based on grant date fair value and recognizes the cost over the period in which the employee is required to provide service in exchange for the award reduced by forfeitures. Equity-based compensation consists of grants of stock options, deferred stock units, common stock, restricted stock units, and performance stock units. Equity-based compensation expense is included as a component of selling, general, and administrative expenses.
Recent accounting pronouncements
The Company considers the applicability and impact of ASUs, and ASUs effective in or after 2022, respectively, were assessed and determined to be either not applicable, or had or are expected to have minimal impact on the Company's consolidated financial statements and related disclosures.

(3) REVENUE
Sales includes revenue from contracts with customers for designing, engineering, manufacturing and installation of solar racking systems; electrical balance of systems; roof and foundation ventilation products; centralized mail systems and electronic package solutions; retractable awnings; gutter guards; rain dispersion products; trims and flashings and other accessories; designing, engineering, manufacturing and installation of greenhouses; structural bearings; expansion joints; pavement sealant; elastomeric concrete; and bridge cable protection systems.
Refer to Note 20 "Segment Information" for additional information related to revenue recognized by timing of transfer of control by reportable segment.
Payment terms and conditions vary by contract, although terms generally include a requirement of payment within a range from 30 to 60 days, or in certain cases, up front deposits. In circumstances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the Company's contracts generally do not include a significant financing component. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from sales.
As of December 31, 2022, the Company's remaining performance obligations are part of contracts that have an original expected duration of one year or less. Additionally, as of December 31, 2022 and 2021, there were no assets recognized related to incremental costs of obtaining a contract with a customer as the benefits of these costs are not expected to exceed one year.
Contract assets consist of costs in excess of billings presented within accounts receivable in the Company's consolidated balance sheets. Contract liabilities consist of billings in excess of cost, classified as current liabilities, and unearned revenue, presented within accrued expenses, in the Company's consolidated balance sheets.

The decreases in costs in excess of billings and billings in excess of cost as of December 31, 2022 compared to December 31, 2021, respectively, were primarily due to decline in volume in the Renewables and Agtech segments in 2022 compared to 2021. The increase in costs in excess of billings as of December 31, 2021 compared to December 31, 2020 was primarily due to the timing of the Company's right to invoice customers for performance satisfied by the Company for significant contracts in the Renewables and Agtech segments near the end of 2021.

The preliminary purchase consideration for the acquisition of QAP was $52.1 million, which includes a preliminary working capital adjustment and certain other adjustments provided for in the membership interest purchase agreement.
The purchase price for the acquisition was preliminarily allocated to the assets acquired and liabilities assumed based upon their respective fair values estimated as of the date of acquisition. The Company has commenced the process to confirm the existence, condition, and completeness of the assets acquired and liabilities assumed to establish fair value of such assets and liabilities and to determine the amount of goodwill to be recognized as of the date of acquisition. Due to the timing of the acquisition, the Company continues to gather information supporting the acquired assets and assumed liabilities. Accordingly, all amounts recorded are provisional. These provisional amounts are subject to change if new information is obtained concerning facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. The final determination of the fair value of certain assets and liabilities will be completed within a measurement period of up to one year from the date of acquisition. The final values may also result in changes to depreciation and amortization expense related to certain assets such as property, plant, and equipment and acquired intangible assets. The preliminary excess consideration was recorded as goodwill and approximated $3.6 million, all of which is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the domestic building products markets. The final purchase price allocation will be completed no later than the third quarter of fiscal year 2023.

Goodwill is recognized net of accumulated impairment losses of $133.2 million as of December 31, 2022 and 2021, respectively. No goodwill impairment charges were recognized by the Company during 2022 or 2021.
Annual and Interim Impairment Testing
The Company tests goodwill and indefinite-lived intangible assets for impairment on an annual basis as of October 31 and at interim dates when indicators of impairment are present. In 2022, 2021 and 2020, no indicators of impairment were identified as of interim dates; therefore, no interim tests were performed.
During the October 31, 2022 impairment test, the Company conducted a quantitative analysis for all eight of the Company’s reporting units. The quantitative impairment test consists of comparing the fair value of a reporting unit with its carrying value including goodwill. The fair value of each reporting unit evaluated under the quantitative test was determined using two valuation techniques: an income approach and a market approach. Each valuation approach relies on significant assumptions including a weighted average cost of capital ("WACC") based upon the capital structure of market participants in the Company’s peer groups, projected revenue growth, forecasted cash flows, and earnings multiples based on the market value of the Company and market participants within its peer groups.
As a result of the Company's annual testing for 2022, 2021 and 2020, none of the reporting units with goodwill as of the testing date had carrying values in excess of their fair values.

Revolving Credit Facility
On December 8, 2022, the Company entered into a Credit Agreement (the "Credit Agreement"), and concurrently with entering into the Credit Agreement, the Company paid off all amounts owed under the Sixth Amended and Restated Credit Agreement dated as of January 24, 2019, and which was terminated without any prepayment penalties. The Credit Agreement provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million. The Company can request additional financing to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Credit Agreement. The Credit Agreement contains two financial covenants. As of December 31, 2022, the Company was in compliance with all financial covenants. The Credit Agreement terminates on December 8, 2027.
Interest rates on the revolving credit facility under the Credit Agreement bear interest, at the Company’s option, at a rate equal to the applicable margin plus (a) a base rate, (b) a daily simple secured overnight financing rate ("SOFR") rate, (c) a term SOFR rate or (d) for certain foreign currencies, a foreign currency rate, in each case subject to a 0% floor. Through March 31, 2023, the Credit Agreement has an initial applicable margin of 0.125% for base rate loans and 1.125% for SOFR and alternative currency loans. Thereafter, the applicable margin ranges from 0.125% to 1.00% for base rate loans and from 1.125% to 2.00% for SOFR and alternative currency loans based on the Company’s Total Net Leverage Ratio, as defined in the Credit Agreement. In addition, the Credit Agreement is subject to an annual commitment fee, payable quarterly, which is initially 0.20% of the daily average undrawn balance of the revolving credit facility and, from and after April 1, 2023, ranges between 0.20% and 0.25% of the daily average undrawn balance of the revolving credit facility based on the Company’s Total Net Leverage Ratio.
Borrowings under the Credit Agreement are secured by the trade receivables, inventory, personal property, equipment, and general intangibles of the Company’s significant domestic subsidiaries. Capital distributions are subject to certain Total Net Leverage Ratio requirements and capped by an annual aggregate limit under the Credit Agreement.
On January 24, 2019, the Company entered into the Sixth Amended and Restated Credit Agreement ("Senior Credit Agreement"), which amended and restated the Company’s Fifth Amended and Restated Credit Agreement dated December 9, 2015, and provided a revolving credit facility and letters of credit in an aggregate amount equal to $400 million. The Company had the ability to request additional financing to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Senior Credit Agreement.
Interest rates on the revolving credit facility under the Senior Credit Agreement were based on LIBOR plus an additional margin that ranges from 1.125% to 2.00%. In addition, the revolving credit facility under the Senior Credit Agreement was subject to an undrawn commitment fee ranging between 0.15% and 0.25% based on the Total Leverage Ratio and the daily average undrawn balance. The Senior Credit Agreement terminated on December 8, 2022.

(10) PENSION AND OTHER POSTRETIREMENT BENEFITS
The Company has a 401(k) plan which all employees of U.S. subsidiaries are eligible to participate.
The Company contributes to a multiemployer defined benefit pension plan under the terms of a collective-bargaining agreement that covers union-represented employees.
The Company has an unfunded postretirement healthcare plan which provides health insurance to certain employees and their spouses upon retirement. This plan has been frozen and no additional participants will be added to the plan in the future.
Total expense for all retirement plans for the years ended December 31 was (in thousands):

The measurement date used to determine postretirement benefit obligation measures was December 31.
Components of net periodic postretirement benefit cost charged to expense for the years ended December 31 were as follows (in thousands):

| 2022 |  | 2021 |  | 2020
Service cost | $ | — |  |  | $ | — |  |  | $ | 10 |
Interest cost | 127 |  |  | 125 |  |  | 172 |
Amortization of unrecognized prior service cost | 60 |  |  | 44 |  |  | 44 |
Loss amortization (2) | 24 |  |  | 113 |  |  | 64 |
Net periodic benefit cost | $ | 211 |  |  | $ | 282 |  |  | $ | 290 |
Assumptions used to calculate the benefit obligation: |  |  |  |  |
Discount rate | 4.8 | % |  | 2.4 | % |  | 2.0 | %
Annual rate of increase in the per capita cost of: |  |  |  |  |
Medical costs before age 65 (1) | 7.8 | % |  | 7.0 | % |  | 7.0 | %
Medical costs after age 65 (1) | 4.5 | % |  | 4.5 | % |  | 4.5 | %
Prescription drug costs (1) | 7.8 | % |  | 7.0 | % |  | 7.0 | %

(1) For 2022, it was assumed that these rates would gradually decline to 4.0% by 2075. For 2021 and 2020, it was assumed that these rates would gradually decline to 3.8% by 2075.
(2) Actuarial losses are amortized utilizing the corridor approach. Differences between actual experience and the actuarial assumptions are reflected in (gain)/loss. If the total net (gain) or loss exceeds 10 percent of the greater of the accumulated postretirement benefit obligation or plan assets, this excess must be amortized over the average remaining service period of the active plan participants. If most of the plan participants are inactive, the amortization period is the expected future lifetime of inactive plan participants.

(12) EQUITY-BASED COMPENSATION
The Company awards equity-based compensation to employees and directors, which is recognized in the statements of operations based on the grant-date fair value of the award. The Company uses the straight-line method for recording compensation expense over a vesting period generally up to four years with either graded or cliff vesting. Stock compensation expense recognized during the period is based on the value of the portion of equity-based awards that is ultimately expected to vest during the period reduced by the expense on unvested awards forfeited during the period.
On May 4, 2022, the stockholders of the Company approved the adoption of the Gibraltar Industries, Inc. Amended and Restated 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") which increases the total number of shares for issuance by the Company thereunder from 100,000 shares to 200,000 shares, allows the Company to grant awards of shares of the Company's common stock to current non-employee Directors of the Company, and permits the Directors to defer receipt of such shares pursuant to the terms of the Non-Employee Directors Plan.
On May 4, 2018, the shareholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2018 Equity Incentive Plan (the "2018 Plan"). The 2018 Plan provides for the issuance of up to 1,000,000 shares of common stock and supplements the remaining shares available for issuance under the existing Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "2015 Plan"). The Company's 2005 Equity Incentive Plan (the "Prior Plan") was amended in 2015 to terminate issuance of further awards from the Prior Plan. Both the 2018 Plan and the 2015 Plan allow the Company to grant equity-based incentive compensation awards, in the form of non-qualified options, restricted shares, restricted stock units, performance shares, performance stock units, and stock rights to eligible participants.

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance or market conditions. The number of shares to be issued may vary between 0% and 200% of the number of PSUs granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on either the Company’s return on invested capital (“ROIC”) over a one-year period performance period or other criteria such as revenue, gross profit, and operating profit thresholds over a three-year performance period. The Company's PSUs with a market condition are based on the ranking of the Company’s total shareholder return (“TSR”) performance, on a percentile basis, over a three-year performance period compared to the S&P Small Cap Industrial sector, over the same three-year performance period.
Stock Options
No options were granted during the years ended December 31, 2022, 2021 and 2020. The Company determines the fair value of stock options granted based on the Black-Scholes option pricing model on the date of grant, and the expected stock volatility is based on volatility of the Company’s stock price using a historical period commensurate with the expected life of the options.

Table of Co n tents
The fair value of the common stock, restricted stock units, and deferred stock units, as well as the performance stock units with a financial performance condition granted during the three years ended December 31, 2022 was based on the Company stock price at grant date of the award. The fair value of the performance stock units with a market condition granted during the three years ended December 31, 2022 were determined using a Monte Carlo simulation as of the grant date of the award. The Company granted performance units with a market condition during 2020; however, no such awards were granted in 2022 and 2021.
The following table sets forth the aggregate intrinsic value of options exercised and aggregate fair value of restricted stock units and restricted shares that vested during the years ended December 31 (in thousands):

As of December 31, 2022, there was $9.3 million of total unrecognized compensation cost related to non-vested restricted and performance stock units. That cost is expected to be recognized over a weighted average period of 2.3 years.
Equity Based Awards - Settled in Cash
Management Stock Purchase Plan
The Company's equity-based awards that are settled in cash are the awards under the Management Stock Purchase Plan (the "MSPP") which is authorized under the Company's equity incentive plans. The MSPP provides participants the ability to defer a portion of their compensation, convertible to unrestricted investments, restricted stock units, or a combination of both, or defer a portion of their directors’ fees, convertible to restricted stock units. Employees eligible to defer a portion of their compensation also receive a company-matching award in restricted stock units equal to a percentage of their deferred compensation.
The deferrals and related company match are credited to an account that represents a share-based liability. The portion of the account deferred to unrestricted investments is measured at fair market value of the unrestricted investments, and the portion of the account deferred to restricted stock units and company-matching restricted stock units is measured at a 200-day average of the Company stock price. The account will be converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.
Total MSPP liabilities recorded on the consolidated balance sheet as of December 31, 2022 were $15.4 million, of which $2.3 million was included in current accrued expenses and $13.1 million was included in non-current liabilities. Total MSPP liabilities recorded on the consolidated balance sheet as of December 31, 2021 were $22.6 million, of which $2.9 million was included in current accrued expenses and $19.7 million was included in non-current liabilities. The value of the restricted stock units within the MSPP liability were $13.4 million and $20.7 million at December 31, 2022 and 2021, respectively.

(13) FAIR VALUE MEASUREMENTS
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows:
•Level 1 - Quoted prices in active markets for identical assets or liabilities.
•Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities.
•Level 3 - Inputs that are unobservable inputs for the asset or liability.
The Company had no financial assets or liabilities measured at fair value on a recurring basis and did not have any financial instruments for which carrying value differed from its fair value at December 31, 2022 and 2021. As of December 31, 2022, the Company had $91.0 million outstanding on its revolving credit facility under its Credit Agreement. The Company determined the carrying value of the outstanding balance on its revolving credit facility approximates fair value due to the variable market interest rate terms of the credit facility. The Company had $24.5 million outstanding on its revolving credit facility as of December 31, 2021.
The Company’s other financial instruments primarily consist of cash and cash equivalents, accounts receivable, notes receivable, and accounts payable. The carrying values for these financial instruments approximate fair value. The Company did not have any other material assets or liabilities carried at fair value and measured on a recurring basis as of December 31, 2022 and 2021.
Other non-recurring fair value measurements
The Company recorded impairment of property, plant and equipment during the years ended December 31, 2022 and 2020, and recognized impairment charges related to certain intangible assets during the year ended December 31, 2021. The Company uses unobservable inputs, classified as Level 3 inputs, in determining the fair value of these assets. See Note 7 "Goodwill and Related Intangible Assets," Note 14 "Held for Sale and Discontinued Operations" and Note 15 "Exit Activity Costs and Asset Impairments" for more disclosure regarding the impairment of certain intangible assets and property, plant, and equipment, respectively.
The Company also applied fair value principles for the goodwill impairment tests performed during 2022, 2021, and 2020. The Company used two valuation models to estimate the fair values of its reporting units, both of which primarily use Level 3 inputs. See Note 7 "Goodwill and Related Intangible Assets" of the consolidated financial statements for the results of the Company’s goodwill impairment tests.
Additionally, the Company's recent acquisition activity, as described in Note 6 "Acquisitions," used Level 3 inputs to estimate fair values allocated to the assets acquired and liabilities assumed.
(14) HELD FOR SALE AND DISCONTINUED OPERATIONS
Held for Sale
During the first quarter of 2022, the Company committed to a plan to sell its Processing business (the "disposal group") which is a business within the Company's Agtech reportable segment. The planned sale does not meet the criteria to be classified as a discontinued operation. As a result, the Company will continue reporting the operating results of the disposal group in the Company's consolidated operating results from continuing operations until the sale of the business is completed.
The Company classifies assets and related liabilities as held for sale when: (i) management has committed to a plan to sell the assets, (ii) the net assets are available for immediate sale, (iii) there is an active program to locate a buyer and (iv) the sale and transfer of the net assets is probable within one year. Assets and liabilities held for sale are presented in prepaid expenses and other current assets and accrued expenses on the Company's consolidated balance sheets with a valuation allowance to recognize the net carrying amount at the lower of cost or fair value, less costs to sell.

Table of Co n tents
As of December 31, 2022, the assets and liabilities of the disposal group have been classified as held for sale. The following table summarizes these assets and liabilities which have been measured at the lower of (i) the carrying value when classified as held for sale and (ii) the fair value of the business less costs to sell.

Effective with the classification of the disposal group as held for sale, depreciation of property, plant, and equipment and amortization of finite-lived intangible assets and right-of-use assets are not recorded while these assets are classified as held for sale. As a result of the Company's evaluation of the recoverability of the carrying value of the assets and liabilities held for sale relative to an estimated sales price, adjusted for costs to sell, a valuation allowance of $14.0 million was recorded during the twelve months ended December 31, 2022 and has been presented within other expense (income) in the consolidated statements of operations. The recoverability of the disposal group will be evaluated each reporting period until the sale of the business is completed.
Discontinued Operations
On February 23, 2021, the Company sold the stock of its Industrial business which had been classified as held for sale and reported as a discontinued operation in the Company’s consolidated financial statements for the years ended December 31, 2021 and 2020. Net proceeds of $38 million, consisting of cash and a $13 million seller note, resulted in an estimated pre-tax loss of $30 million, subject to working capital and other adjustments, of which $29.6 million was recorded when the assets of the Industrial business were written down to fair market value during the fourth quarter of 2020. The seller note was paid in full to the Company during the second quarter of 2021.
The results of operations of the Industrial business have been presented as a discontinued operation in the Company's consolidated financial statements for all periods presented. The Company allocates interest to its discontinued operations in accordance with ASC Subtopic 205-20, “Presentation of Financial Statements – Discontinued Operations.” Interest was allocated based on the amount of net assets held by the discontinued operation in comparison to consolidated net assets.

On June 30, 2020, the Company sold its self-guided apartment tour application business to a third party from its Residential segment. The $2.0 million net proceeds from the sale resulted in pre-tax net gain of $1.9 million and has been presented within other expense (income) in the consolidated statements of operations. This divestiture did not meet the criteria to be reported as a discontinued operation nor did it have a major effect on the Company's operations.
(15) EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS
The Company has incurred exit activity costs and asset impairment charges as a result of its 80/20 simplification and portfolio management initiatives. These initiatives have resulted in the identification of low-volume, low margin, internally-produced products which have been or will be outsourced or discontinued, the simplification of processes, in the sale and exiting of less profitable businesses or products lines, and the reduction in the Company's manufacturing footprint.
Exit activity costs were incurred during 2022 related to moving and closing costs, severance and contract terminations, along with asset impairment charges related to the write-down of inventory and impairment of machinery and equipment associated with discontinued product lines, as a result of process simplification initiatives. In conjunction with these initiatives, in 2022, the Company exited a facility, relocating to a new one, and separately, closed two other facilities. In 2021, the Company closed four facilities. In 2020, the Company closed two facilities and, separately, sold a facility closed in 2017. These closures resulted in exit activity costs and asset impairment charges.
The following table sets forth the exit activity costs (recoveries) and asset impairment charges incurred by segment during the years ended December 31 related to the restructuring activities described above (in thousands):

(16) INCOME TAXES
The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse.

At December 31, 2022, the Company had total net operating loss carry forwards of $7.9 million, which included $0.4 million for federal, $6.6 million for state, and $0.9 million for foreign income tax purposes. The federal and state net operating loss carry forwards expire between 2023 and 2042. The foreign net operating loss carry forwards expire between 2023 and 2031. The Company recognized a total of $0.7 million of deferred tax assets, net of the federal tax benefit, related to these net operating losses prior to any valuation allowances, which included $0.1 million of federal and $0.4 million of state deferred tax assets and $0.2 million of foreign deferred tax assets.
As a result of the sale of the Industrial business during 2021, the Company generated a capital loss of $113.7 million for federal and state purposes to the extent allowable under state tax regulations. Amended Federal returns were filed to carry back $3.7 million of capital loss. As of December 31, 2022, the remaining capital loss carry forward is $110.0 million. The capital loss carryforward will expire in 2026. The Company recognized a total of $26.5 million of deferred tax assets, net of the federal benefit, related to this carryforward prior to any valuation allowances, which included $22.2 million of federal and $4.3 million of state deferred tax assets. The Company has a full valuation allowance on the capital loss carry forward and as a result there is no deferred tax asset.
Deferred taxes include net deferred tax assets relating to certain state and foreign tax jurisdictions. A reduction of the carrying amount of deferred tax assets by a valuation allowance is required if it is more likely than not that such assets will not be realized. In 2020, the valuation allowance in China was reversed and a tax attribute valuation allowance was also reversed as the Company expects to utilize the attribute. In 2021, a valuation allowance was recorded on federal and state capital loss carry forwards which are not expected to be utilized before expiration.
The following sets forth a reconciliation of the beginning and ending amount of the Company’s valuation allowance (in thousands):

At December 31, 2022, the Company had approximately $2.2 million of undistributed earnings of foreign subsidiaries. The Company continues to maintain its assertion that all remaining foreign earnings will be indefinitely reinvested. Any excess earnings could be used to grow the Company's foreign operations through launches of new capital projects or additional acquisitions. Determination of the amount of unrecognized deferred U.S. income tax liability related to the Company's remaining unremitted foreign earnings is not practicable due to the complexities associated with its hypothetical calculation.
In 2022, 2021 and 2020, the Company did not have any unrecognized tax benefits and no activity related to such benefits has occurred in any of the years presented in the consolidated financial statements. The Company classifies accrued interest and penalties related to unrecognized tax benefits in income tax expense. No interest or penalties have been recognized during the years ended December 31, 2022, 2021 or 2020.
The Company and its U.S. subsidiaries file a U.S. federal consolidated income tax return. Foreign and U.S. state jurisdictions have statute of limitations generally ranging from four to ten years. The Company is currently in appeals for an audit of tax years 2016 through 2019 in Massachusetts and believes the technical merits of the position will be sustained.

(17) EARNINGS PER SHARE
Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding, as well as dilutive common shares which include shares issuable pursuant to equity based incentive compensation awards under the equity compensation plans described in Note 12 "Equity-Based Compensation" of the consolidated financial statements.
Weighted average shares outstanding for basic and diluted earnings were as follows for the years ended December 31 (in thousands):

The weighted average number of diluted shares does not include potential anti-dilutive common shares issuable pursuant to equity based incentive compensation awards. The treasury stock method is used to calculate dilutive shares, which reduces the gross number of dilutive shares by the number of shares purchasable from the proceeds of the options assumed to be exercised and the unrecognized expense related to the options, restricted shares, restricted stock units, and performance stock units assumed to have vested.
The following table provides the potential anti-dilutive common stock options and stock units for the years ended December 31 (in thousands):

(18) LEASES
The Company's leases are classified as operating leases and consist of manufacturing facilities, distribution centers, office space, vehicles and equipment.
Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from one month to fifteen years. The exercise of lease renewal options is at the Company's sole discretion. As of December 31, 2022 and 2021, the Company's renewal options are not part of the Company's operating lease assets and operating lease liabilities. Certain leases also include options to purchase at fair value the underlying leased asset at the Company's sole discretion.

The Company uses the its incremental borrowing rate based on information available at the commencement date of a lease in determining the present value of lease payments as the rates implicit in most of the Company's leases are not readily determinable.
(19) COMMITMENTS AND CONTINGENCIES
The Company is a party to certain claims and legal actions generally incidental to its business. Management does not believe that the outcome of any claims, or other claims which are not clearly determinable at the present time, would result in a material adverse effect on the Company's financial condition or results of operations.

(20) SEGMENT INFORMATION
The Company is organized into four reportable segments on the basis of the production processes, products and services provided by each segment, identified as follows:
(i)Renewables, which primarily includes designing, engineering, manufacturing and installation of solar racking and electrical balance of systems;
(ii)Residential, which primarily includes roof and foundation ventilation products, centralized mail systems and electronic package solutions, retractable awnings and gutter guards, and rain dispersion products, trims and flashings and other accessories;
(iii)Agtech, which provides growing solutions including the designing, engineering, manufacturing and installation of greenhouses; and
(iv)Infrastructure, which primarily includes structural bearings, expansion joints and pavement sealant for bridges, airport runways and roadways, elastomeric concrete, and bridge cable protection systems.
When determining the reportable segments, the Company aggregated operating segments based on their similar economic and operating characteristics. During the first quarter of 2021, the Company reassessed its reportable segments. As a result, the Company's former Renewable Energy and Conservation segment was divided into two reportable segments: Renewables and Agtech.

Item 9A. | Controls and Procedures

Evaluation of Disclosure Controls and Procedures
The Company maintains a system of disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Management of the Company, under the supervision and with the participation of the Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered in this report. Based upon that evaluation and the definition of disclosure controls and procedures contained in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, the Company’s Chief Executive Officer, and Chief Financial Officer have concluded that as of the end of such period the Company’s disclosure controls and procedures were effective.
Management’s Annual Report on Internal Control Over Financial Reporting
The management of Gibraltar Industries, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting for the Company, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Under the supervision and with the participation of management, including the Company’s Chief Executive Officer and the Chief Financial Officer, the Company conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on the Company’s evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2022.
The Company's acquisition of Quality Aluminum Products ("QAP") was excluded from management's annual report on internal control over financial reporting as of December 31, 2022. The Company acquired QAP on August 22, 2022. The results of QAP are included in the Company's 2022 consolidated financial statements and were $53.9 million of total assets and $51.1 million of net assets, respectively, as of December 31, 2022, and $26.4 million and $(1.0) million of net sales and net income, respectively, for the year then ended.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2022 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included below in this Item 9A of this Annual Report on Form 10-K.
Changes in Internal Control over Financial Reporting
There have been no changes in the Company’s internal control over financial reporting (as defined by Rule 13a-15(f)) that occurred during the three months ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors of Gibraltar Industries, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Gibraltar Industries, Inc.’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Gibraltar Industries, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.
As indicated in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Quality Aluminum Products which is included in the 2022 consolidated financial statements of the Company and constituted 4.4% and 6.1% of total and net assets, respectively, as of December 31, 2022 and 1.9% and (1.0%) of net sales and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Quality Aluminum Products.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2022 consolidated financial statements of the Company and our report dated February 22, 2023 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible 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 Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
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.
73

Table of Co n tents
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.
