Business PART I Unless otherwise indicated, the terms “the Company,” “we,” “our,” and “us” are used in this 2022 Form 10‑K to refer to Northwest Pipe Company or one of our consolidated subsidiaries or to all of them taken as a whole. We were incorporated in the State of Oregon in 1966. Overview Northwest Pipe Company is a leading manufacturer of water-related infrastructure products. In addition to being the largest manufacturer of engineered steel water pipeline systems in North America, we manufacture stormwater and wastewater technology products; high-quality precast and reinforced concrete products; pump lift stations; steel casing pipe, bar-wrapped concrete cylinder pipe, and one of the largest offerings of pipeline system joints, fittings, and specialized components. Strategically positioned to meet growing water and wastewater infrastructure needs, we provide solution-based products for a wide range of markets under the ParkUSA, Geneva Pipe and Precast, Permalok®, and Northwest Pipe Company lines. Our diverse team is committed to quality and innovation while demonstrating our core values of accountability, commitment, and teamwork. We are headquartered in Vancouver, Washington, and have 13 manufacturing facilities across North America. Our water infrastructure products are sold generally to installation contractors, who include our products in their bids to federal, state, and municipal agencies, privately-owned water companies, or developers for specific projects. We believe our sales are substantially driven by spending on urban growth and new water infrastructure with a recent trend towards spending on water infrastructure replacement, repair, and upgrade. Within the total range of products, our steel pipe tends to fit the larger-diameter, higher-pressure pipeline applications, while our precast concrete products mainly serve stormwater and sanitary sewer systems. With steady population growth and regional community expansion, as well as continued drought conditions, existing water sources have become stressed, and we see continued opportunities for growth in North American infrastructure. Recent Strategic Actions On October 5, 2021, we completed the acquisition of 100% of Park Environmental Equipment, LLC (ParkUSA) for a purchase price of $90.2 million in cash, which is included in the Precast Infrastructure and Engineered Systems (“Precast”) segment for all periods following the acquisition date. ParkUSA is a precast concrete and steel fabrication-based company that develops and manufactures water, wastewater, and environmental solutions. Operations continue with ParkUSA’s previous management and workforce at its three Texas manufacturing facilities located in Houston, Dallas, and San Antonio. This strategic acquisition provides a foothold into the water infrastructure technology market. As we employ similar operating capabilities at our existing facilities, we intend to explore strategic opportunities to expand ParkUSA’s value-added products within the organization. On January 31, 2020, we completed the acquisition of 100% of Geneva Pipe and Precast Company (“Geneva”) (fka Geneva Pipe Company, Inc.) for a purchase price of $49.4 million in cash, which is included in the Precast segment for all periods following the acquisition date. Geneva is a concrete pipe and precast concrete products manufacturer based in Utah. This acquisition expanded our water infrastructure product capabilities by adding additional reinforced concrete pipe capacity and a full line of precast concrete products including storm drains and manholes, catch basins, vaults, and curb inlets as well as innovative lined products that extend the life of concrete pipe and manholes for sewer applications. Operations continue with Geneva’s previous management and workforce at its three Utah manufacturing facilities. Impact of the COVID‑19 Pandemic on Our Business In March 2020, the World Health Organization declared COVID‑19 a pandemic. The impacts of the COVID‑19 pandemic, and the resurgence of new COVID‑19 virus variants, on global and domestic economic conditions, including the impacts of labor and raw material shortages, the long-term potential to reduce or delay funding of municipal projects, and the continued disruptions to and volatility in the financial markets remain uncertain. While the COVID‑19 pandemic has caused various direct and indirect financial impacts associated with project bidding, execution, and product deliveries over the past couple of years, we remain unable to predict the ultimate impact that the COVID‑19 pandemic may have on our business, future results of operations, financial position, or cash flows. We continue to monitor the impact of the COVID‑19 pandemic on all aspects of our business. 2 Table of Contents Our Segments Engineered Steel Pressure Pipe (“SPP”). SPP manufactures large-diameter, high-pressure steel pipeline systems for use in water infrastructure applications, which are primarily related to drinking water systems. These products are also used for hydroelectric power systems, wastewater systems, seismic resiliency, and other applications. In addition, SPP makes products for industrial plant piping systems and certain structural applications. SPP has manufacturing facilities located in Portland, Oregon; Adelanto and Tracy, California; Parkersburg, West Virginia; Saginaw, Texas; St. Louis, Missouri; and San Luis Río Colorado, Mexico. Precast Infrastructure and Engineered Systems (Precast). Precast manufactures stormwater and wastewater technology products, high-quality precast and reinforced concrete products, including manholes, box culverts, vaults, and catch basins, pump lift stations, oil water separators, biofiltration, and other environmental and engineered solutions. Precast has manufacturing facilities located in Dallas, Houston, and San Antonio, Texas; and Orem, Salt Lake City, and St. George, Utah. Our Industries Much of the United States water infrastructure is antiquated and many authorities, including the United States Environmental Protection Agency (“EPA”), believe the United States water infrastructure is in critical need of update, repair, or replacement. A combination of new population centers, rising demand on developed water sources, substantial underinvestment in water infrastructure over the past several decades, drought conditions, climate change, and increasingly stringent regulatory policies are driving demand for water infrastructure projects in the United States. These trends are intensifying the need for new water infrastructure as well as the need to upgrade, repair, and replace existing water infrastructure. While we believe this offers the potential for increased demand for our water infrastructure products and other products related to water transmission, budgetary pressures could impact governmental and public water agency projects in the near-term. Federal initiatives to improve the conditions of the aging water infrastructure include the Water Infrastructure and Resiliency Finance Center at the EPA and the Water and Environmental Programs at the U.S. Department of Agriculture. The Bipartisan Infrastructure Deal (Infrastructure Investment and Jobs Act), signed into law in November 2021, will invest $55 billion to expand access to clean drinking water for households, businesses, schools, and child care centers all across the country. According to its 2021 Annual Report, the EPA’s Water Infrastructure Finance and Innovation Act program, a federal credit program for eligible water and wastewater infrastructure projects, closed 31 loans totaling over $5 billion in 2021. In addition to the Federal initiatives, individual states are also taking action. In November 2013, the State of Texas earmarked $27 billion of future bond funding for state water projects over the next 50 years through their State Water Implementation Fund for Texas (SWIFT). This program provides low- interest and deferred loans to state agencies making approved investments in water infrastructure projects. In November 2014, the State of California approved the Water Quality, Supply and Infrastructure Improvement Act which authorizes $7.5 billion in general obligation bonds to fund state water supply infrastructure projects, such as public water system improvements, surface and groundwater storage, drinking water protection, water recycling and advanced water treatment technology, water supply management and conveyance, wastewater treatment, drought relief, emergency water supplies, and ecosystem and watershed protection and restoration. Our strategically located manufacturing facilities are well-positioned to take advantage of the anticipated growth in demand. Engineered Steel Pressure Pipe. In its Sixth Drinking Water Infrastructure Needs Survey and Assessment released in March 2018, the EPA estimated the nation will need to spend $473 billion on public water system infrastructure capital improvements from 2015 to 2034 to continue to provide safe drinking water to the public. The American Society of Civil Engineers (“ASCE”) has given poor ratings to many aspects of the United States water infrastructure in their 2021 Infrastructure Report Card for Drinking Water. The Failure to Act: Economic Impacts of Status Quo Investment Across Infrastructure Systems report published by ASCE and EBP in 2021, estimates there will be $2.6 trillion in cumulative infrastructure needs for water and wastewater infrastructure by 2029, and $5.8 trillion in cumulative infrastructure needs by 2039. The American Water Works Association concluded in their 2012 report, Buried No Longer: Confronting America’s Water Infrastructure Challenge, that from 2011 to 2035 more than $1 trillion will be needed to repair and expand drinking water infrastructure. According to the United States Census Bureau, the population of the United States will increase by approximately 52 million people between 2023 and 2050. The resulting increase in demand will require substantial new infrastructure, as the existing United States water infrastructure is not equipped to provide water to millions of new residents. The development of new sources of water at greater distances from population centers will drive the demand for new water transmission lines. Climate change may be a cause for the drought conditions in some regions of the country and are increasing the demand for new infrastructure. The Construction Outlook 2023 from Dodge Construction Network forecasts public works construction in 2023 will grow 18%, supported by several recent federal legislative initiatives that have provided ample funding for infrastructure projects over the coming year. 3 Table of Contents As water systems degrade over time and cause failures, many current water supply sources are in danger of being exhausted. Much of the drinking water infrastructure in major cities was built in the mid-20th century with a lifespan of 75 to 100 years. In its 2021 Infrastructure Report Card for Drinking Water, the ASCE estimates there are 250,000 to 300,000 water main breaks per year in the United States, wasting over 2.1 trillion gallons of treated drinking water. The ASCE also reports that with utilities averaging a pipe replacement rate of 1.0% to 4.8% per year, the replacement rate now matches the lifecycle of the pipes. These aging water and wastewater systems will drive demand for future investment. The Drinking Water State Revolving Loan Fund (“DWSRF”), a federal-state partnership and financial assistance program to help water systems and states achieve the health protection objectives of the Safe Drinking Water Act, provided $3.8 billion in assistance in 2021 and $48.5 billion in assistance since 1997, according to the 2021 DWSRF Annual Report. Finally, the increased public awareness of problems with the quality of drinking water and efficient water usage has resulted in more stringent application of federal and state environmental regulations. The need to comply with these regulations in an environment of heightened public awareness is expected to contribute to demand in the water infrastructure industry. Our large-diameter, engineered welded steel pipeline systems are utilized in water, energy, structural, and plant piping applications. Our core market is the large-diameter, high-pressure portion of a water transmission pipeline that is typically at the “upper end” of a pipeline system. This is the portion of the overall water pipeline that generally transports water from the source to a treatment plant or from a treatment plant into the distribution system, rather than the small lines that deliver water directly into households. We believe the total addressable market for the engineered welded steel pipeline system products sold will be approximately $2.0 billion over the next three years. Precast Infrastructure and Engineered Systems. In its 2021 Infrastructure Report Card for Wastewater, the ASCE estimates the drinking water and wastewater pipes in the ground, with a typical lifespan expected of 50 to 100 years, are on average 45 years old. In 2020, Bluefield Research estimated that utilities throughout the country will spend more than $3 billion on wastewater pipe repairs and replacements, addressing 4,692 miles of wastewater pipeline, and this cost is projected to grow by an average of 5% annually. In its 2021 Infrastructure Report Card for Stormwater, the ASCE states that given the recent increase in rainfall trends and urbanization in certain geographic regions, the actual capacity of a stormwater system is often less than the design standard. In addition, from 2010 to 2018 the length of impaired rivers and streams increased 39%, a key indicator of declining stormwater infrastructure condition. Our high-quality precast and reinforced concrete products and bar-wrapped concrete cylinder pipe are typically used in non-pressure, gravity fed sewer and stormwater applications. Demand for these products is generally influenced by general economic conditions such as housing starts, population growth, and interest rates. New residential and commercial construction and state Department of Transportation funding impact our market. The November 2022 Bluefield Research Insight Report – U.S. & Canada Municipal Water Outlook: Utility CAPEX & OPEX Forecasts, 2022-2030 (“Bluefield Report”) states that since the peak of new U.S. home construction in March 2022, interest rate hikes have dissuaded potential new homebuyers from entering the market. According to the United States Census Bureau, the privately-owned housing starts in December 2022 were at a seasonally adjusted annual rate of 1.4 million, compared to a seasonally adjusted annual rate of 1.8 million in December 2021. However, our Precast manufacturing facilities are located in Texas, one of three states with the largest infrastructure asset base, and Utah; both of these states are in the top five of the fastest growing markets (based on compound annual growth rate forecasted through 2030), according to the Bluefield Report. Backlog Engineered Steel Pressure Pipe. We measure backlog as a key metric to evaluate the commercial health of our water infrastructure steel pipe business. Backlog represents the balance of remaining performance obligations under signed contracts for SPP products for which revenue is recognized over time. Binding agreements received by us may be subject to cancelation or postponement; however, cancelation would obligate the customer to pay the contract consideration proportional to the costs we have incurred through the cancelation date. As of December 31, 2022 and 2021, backlog was $274 million and $183 million, respectively. Backlog as of any particular date may not be indicative of actual operating results for any fiscal period. There can be no assurance that any amount of backlog ultimately will be realized. Separate from our backlog, we have been notified that we are the successful bidder on additional projects, but binding agreements have not been executed (“confirmed orders”). As of December 31, 2022 and 2021, backlog including confirmed orders was $372 million and $290 million, respectively. Projects for which a binding agreement has not been executed could be canceled. 4 Table of Contents Products Engineered Steel Pressure Pipe. Water infrastructure steel pipe is used for high-pressure applications, typically requiring pipe to withstand pressures in excess of 150 pounds per square inch. Most of our water transmission products, mainly welded steel pipe and bar-wrapped cylinder pipe, are made to project specifications for fully engineered, large-diameter, high-pressure water infrastructure systems. Other uses include power generation circulating water systems, penstocks, pipe piling, and water and wastewater treatment plants. Spiral welded pipe is manufactured in diameters ranging from 24 inches to 156 inches with wall thickness of 0.135 inches to 1.00 inch. Our rolled and welded capabilities allow for manufacturing diameters greater than 156 inches or wall thicknesses exceeding 1.00 inch. Lining and coating capabilities include cement mortar, polyurethane, epoxy, polyethylene tape, and coal-tar enamel according to our customers’ project specifications. Fabrication of fittings are performed at our own facilities providing installation contractors and project owners with a complete engineered system. Product is delivered to the jobsite using commercial trucks or marine transport as needed. We manufacture Permalok® steel casing pipe, which is a proprietary pipe joining system that employs a press-fit interlocking connection system. The Permalok® product is generally installed in trenchless construction projects. Precast Infrastructure and Engineered Systems. We manufacture a variety of high-quality precast concrete products for water and adjacent infrastructure applications. Our precast products include reinforced concrete pipe (“RCP”), manholes, box culverts, vaults, catch basins, oil water separators, pump lift stations, lined RCP and manholes, and other precast infrastructure products. The Geneva facilities manufacture RCP in sizes ranging from twelve inches to 96 inches in diameter and in a variety of strength classes at ASTM International and American Association of State Highway and Transportation Officials (“AASHTO”) specifications which are primarily used for water transmission, sanitary sewer systems, storm drainage, and utilities fabrication. Geneva’s manholes, box culverts, vaults, and other structural products come in a variety of dimensions. Geneva’s lined products include high-density polyethylene (“HDPE”) or fiber reinforced plastic internal liners within manholes and RCP with additional corrosion protection in sanitary sewer and wastewater environments. Under the ParkUSA brand, we manufacture pre-assembled stormwater, wastewater, and water management systems housed predominantly in precast concrete or steel housings, including water meter assemblies, break tank systems, pump lift stations, and backflow prevention systems. ParkUSA also manufactures a variety of stormwater products including catch basins, canal valves, and interceptors capable of removing sediments, trash, and oil from stormwater runoff. ParkUSA’s wastewater products protect the environment and limit pollutants from entering sewer systems including interceptors designed to neutralize and macerate foreign materials such as fats, oils, and greases in wastewater for hospitals, service stations, restaurants, and other commercial applications. ParkUSA units are pre-assembled in a quality-controlled environment and are delivered ready to install to the job site, providing significant savings from onsite assembly. Manufacturing and Product Development Engineered Steel Pressure Pipe. Water infrastructure steel pipe manufacturing begins with the preparation of engineered drawings of each unique piece of pipe in a project. These drawings are prepared on our proprietary computer-aided design system and are used as blueprints to manufacture pipe. After the drawings are completed and approved, the manufacturing of engineered steel water pipe begins by feeding a steel coil continuously at a specified angle into a spiral weld mill which cold-forms the band into a tubular configuration with a spiral seam. Automated arc welders, positioned on both the inside and the outside of the tube, are used to weld the seam. The welded pipe is then cut at the specified length. After completion of the forming and welding phases, the finished cylinder is tested and inspected in accordance with project specifications, which may include 100% radiographic analysis of the weld seam. The cylinders are then coated and lined as specified. Possible coatings include polyurethane paint, polyethylene tape, epoxy, cement mortar, coal-tar enamel, and Pritec®. The inside of the pipe cylinders can be lined with cement mortar, polyurethane, or epoxy. Following coating and lining, certain pieces may be custom fabricated as required for the project. This process is performed at our on-site fabrication facilities. Completed pipes are evaluated for structural integrity with a hydrotester prior to shipment. In April 2022, we introduced the Permalok® Auger Bore Joint, which utilizes a precision-machined interference fit that eliminates the need for time- sensitive field applied butt-welds on trenchless and open-cut applications. This patented pre-installed joint connection is flush with the interior and exterior surfaces of the pipe, allowing for quick, easy, and permanent joining in the field. Its unique stepped profile simplifies installation for our customers. In November 2022, we announced the development of the Permalok® Radial Bending Joint. This patent-pending technology is a groundbreaking advancement in trenchless microtunneling construction allowing steel pipe to be installed in a curved radius. As with other Permalok joints, the press-fit machined joint reduces field time by eliminating butt-weld joints and results in a shortened install duration and reduced field costs. 5 Table of Contents Precast Infrastructure and Engineered Systems. Precast concrete products are manufactured using either a dry cast or wet cast concrete mix, depending on the size of the piece and the number of identical pieces to be manufactured. In the dry cast method, a concrete mix with low water content, known as zero-slump concrete, is poured into a mold and then densely compacted around the steel reinforcement using a variety of manufacturing methods. The concrete structure is immediately removed from the mold and allowed to cure in a high humidity environment to ensure proper hydration of the concrete. This method allows multiple pieces to be produced from the same mold each day and is most suitable for high volume, repetitive manufacturing. We also manufacture reinforced concrete pipe by producing a steel mesh cage, enclosing it in a form or mold, and then pouring concrete around it to produce the pipe. In the wet cast method, a concrete mix with relatively high water content is poured into a mold and allowed to cure in the mold, which can take from four to 16 hours. We work hand-in-hand with our customers to develop custom water infrastructure products that help protect the environment. Many of our precast wastewater, stormwater, water management, and process systems include integrated Original Equipment Manufacturer components that we build out at our facilities into the finished solution. We build and test each unit to industry standards in our quality-controlled certified facilities. The units arrive at the jobsite ready to install, which reduces jobsite construction time and the need for specialized trades on site. Technology. Advances in technology help us produce high-quality products at competitive prices. We have invested in modern welding and inspection equipment to improve both productivity and product quality. We own interlocking pipe joining system technologies (Permalok®) that provide an alternate joint solution used for connecting steel pipes. In addition, we are licensed to manufacture a conventional reinforced concrete pipe with a HDPE liner to protect concrete pipe from corrosion, and a lined manhole system, which integrates a precast concrete monolithic base with a plastic liner that is chemically resistant to raw sewage gases. ParkUSA also holds several patents for commercially viable products. To stay current with technological developments in the United States and abroad, we participate in trade shows, industry associations, research projects, and vendor trials of new products. Our staff includes some of the most tenured and experienced pipe manufacturing professionals in the nation. Intellectual Property. We own various patents, registered trademarks and trade names and applications for, or licenses in respect of the same, that relate to our various products, including a number of innovative technologies relating to water infrastructure as well as precast infrastructure and engineered systems produced by ParkUSA. We also license intellectual property for use in certain of our products from unaffiliated third parties. We believe that our patents, trademarks, and trade names are adequately protected and that any expiration or other loss of one or more of our patents or other intellectual property rights would not have a material adverse effect upon our business, financial condition, or results of operations. Quality Assurance. We have quality management systems in place that assure we are consistently providing products that meet or exceed customer and applicable regulatory requirements.

Our seven steel pipe manufacturing facilities in Oregon, California, West Virginia, Texas, Missouri, and Mexico allow us to efficiently serve customers throughout North America. The primary customers for our water infrastructure steel pipe products are installation contractors for projects funded by public water agencies. Our marketing strategy emphasizes early identification of potential water projects, promotion of specifications consistent with our capabilities and products, and close contact with the project designers and owners throughout the design phase. Our in- house sales force is comprised of sales representatives, engineers, and support personnel who work closely with public water agencies, contractors, and engineering firms, often years in advance of a project bid date. These relationships allow us to identify and evaluate planned projects at early stages, and pursue these projects by offering technical support and resources. After an agency completes a design, they publicize the upcoming bid for a water transmission project. We then obtain detailed plans and develop our estimate for the pipe portion of the project. We typically bid to installation contractors who include our bid in their proposals to public water agencies. A public water agency generally awards the entire project to the contractor with the lowest responsive bid. Precast Infrastructure and Engineered Systems. Our six precast and water systems manufacturing facilities in Texas and Utah allow us to efficiently serve customers throughout Texas, the Intermountain West region, and surrounding states. The primary customers for our precast infrastructure and reinforced concrete products are installation contractors for various commercial, government, residential, and industrial projects. Our marketing strategy emphasizes our product quality and variety of offerings, competitive pricing, customer service, delivery, and technical expertise. We market many of our engineered systems with preinstalled components as having the advantage of reduced field install time, the elimination of multiple vendors, and higher quality control. Our sales force is comprised of in-house and third-party sales representatives, engineers, and support personnel who work closely with the customers to find the right product or solution for their specific need. Competition Engineered Steel Pressure Pipe. Most water infrastructure steel pipe projects are competitively bid and price competition is vigorous. Price competition may reduce the gross margin on sales, which may adversely affect overall profitability. Other competitive factors include timely delivery, customized specifications, and high freight costs which may limit the ability of manufacturers located in other market areas to compete with us. With water infrastructure steel pipe manufacturing facilities in Oregon, California, West Virginia, Texas, Missouri, and Mexico, we believe we can more effectively compete throughout North America. Our primary competitors in the western United States and southwestern Canada are Imperial Pipe and West Coast Pipe. East of the Rocky Mountains, our primary competitors are Thompson Pipe Group, American SpiralWeld Pipe, and Mid America Pipe Fabricating & Supply, LLC. Our competitors could build new facilities or expand capacity within our market areas. In 2019, a competitor broke ground on a new spiral welded steel pipe facility in Texas that became operational in the first half of 2021. New or expanded facilities or new competitors could have a material adverse effect on our market share, product pricing, sales, gross margins, and overall profitability in our business. Precast Infrastructure and Engineered Systems. Our six precast and reinforced concrete product manufacturing facilities in Texas and Utah have several local competitors which are primarily other precast concrete manufacturers in the respective states where we operate. Our primary competitors are Oldcastle Infrastructure in Texas and Utah and The QUIKRETE Companies in Texas. Raw Materials and Supplies We have at least two suppliers for most of our raw materials. We believe our relationships with our suppliers are positive and do not expect that we will experience shortages of raw materials or components essential to our production processes or that we will be forced to seek alternative sources of supply. Any shortages of raw materials may result in production delays and costs, which could have a material adverse effect on our financial position, results of operations, or cash flows. Engineered Steel Pressure Pipe. The main raw component in our steel pipe manufacturing process is steel. We have historically purchased hot rolled steel coil and steel plate from both domestic and foreign steel mills. Our suppliers include Big River Steel, Steel Dynamics, Inc., United States Steel Corporation, ArcelorMittal, SSAB, POSCO INTERNATIONAL, EVRAZ North America, California Steel Industries, Cleveland-Cliffs Inc., and Nucor Corporation. Steel is normally purchased after the steel pressure pipe orders are confirmed with an executed contract. Purchased steel represents a substantial portion of our cost of sales. The steel industry is highly cyclical in nature and steel prices fluctuate significantly, influenced by numerous factors beyond our control, including general economic conditions, availability of raw materials, energy costs, import duties, other trade restrictions, and currency exchange rates. 7 Table of Contents Precast Infrastructure and Engineered Systems. The main raw components in our precast and reinforced concrete products are cement, steel, and aggregate, which are widely available commodities. When possible, we source these raw materials from suppliers near our facilities. During 2022, we experienced supply chain challenges for cement resulting from historically high demand as well as equipment outages, which led to suppliers allocating cement to customers in both Texas and Utah. We also rely on certain suppliers of valves, pumps, piping, and certain custom fabricated items, and experienced supply chain challenges for some of these materials during periods of the year. Seasonality Our operations can be affected by seasonal variations and our results tend to be stronger in the second and third quarters of each year due to typically milder weather in the regions in which we operate. We are more likely to be impacted by severe weather events, such as hurricanes and excessive flash flooding, snow, ice, or frigid temperatures, which may cause temporary, short-term anomalies in our operational performance in certain localized geographic regions. However, these impacts usually have not been material to our operations as a whole. See Part I — Item 1A. “Risk Factors” of this 2022 Form 10‑K for further discussion. Government Regulations We are subject to various environmental, health, and employee safety laws and regulations. We believe we are in material compliance with these laws and regulations and do not currently believe that future compliance with such laws and regulations will have a material adverse effect on our capital expenditures, earnings, or competitive position. Nevertheless, we cannot guarantee that, in the future, we will not incur additional costs for compliance or that such costs will not be material. In particular, we are subject to federal, state, local, and foreign environmental regulations, violations of which could lead to fines, penalties, other civil sanctions, or criminal sanctions. These environmental laws and regulations govern emissions to air; discharges to water; and the generation, handling, storage, transportation, treatment, and disposal of waste materials. We operate under numerous governmental permits and licenses relating to air emissions, stormwater runoff, and other environmental matters. We are subject to environmental laws requiring the investigation and cleanup of environmental contamination at properties we presently own or operate and at third-party disposal or treatment facilities to which these sites send or arrange to send hazardous waste. For example, we have been identified as a potentially responsible party at the Portland Harbor Superfund Site discussed in Note 15 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Estimating liabilities for environmental investigations and cleanup is complex and dependent upon a number of factors beyond our control which may change dramatically. We have no reserves for environmental investigation or cleanup, and we believe this is appropriate based on current information; however, we cannot provide assurance that our future environmental investigation and cleanup costs and liabilities will not result in a material expense. Human Capital Resources At Northwest Pipe Company, we believe that a commitment to developing our Human Capital Resources is necessary to maintain our position as a leader in our marketplace. Key issues of culture, health and safety, and diversity and inclusion are key priorities in our discussions of our environmental, social, and governance (ESG) impact. Employees. As of December 31, 2022, we had 1,312 employees, the overwhelming majority of which were full-time. Approximately 66% of our workforce is employed on an hourly basis, while 34% is salaried. Approximately 5% of our employees are subject to a collective bargaining agreement with a single labor union. We consider our relations with our employees and the labor union to be good. The weighted-average tenure of our employees is 8 years of service. Maintaining a sufficient number of skilled employees in order to support the operations at our corporate office and various manufacturing sites continues to be a key focus at Northwest Pipe Company. To that end, we offer a wide array of company-paid benefits to our employees both in the United States and Mexico. Benefits may vary between countries due to customary local practices and statutory requirements, or due to an employee’s full or part time status, work location, position, or tenure; however, we believe that as a whole our compensation packages are competitive relative to others in our industry. We are committed to ensuring equal pay for equal work regardless of an employee’s age, gender identity, race, ethnicity, sexual orientation, or physical or mental ability. Culture. Our key values are captured in the acronym ACT, which stands for Accountability, Commitment, and Teamwork, which we seek to demonstrate in our daily actions. Our executive leadership team guides our strategic direction to provide innovative water, environmental, and other infrastructure solutions for a wide range of commercial, residential, and municipal applications which are manufactured safely (see Health and Safety below) and efficiently. As a trusted partner to engineering firms, contractors, and water municipalities, we strive for operational, manufacturing, and client service excellence. Our success stems from our employees delivering product to our customers that consistently meets or exceeds their expectations. 8 Table of Contents We believe that our employees are our best resources. In order to recognize and reward the continued commitment and teamwork of our employees, when positions that may offer opportunities for advancement become open at Northwest Pipe Company, we first try to fill those positions from within. We are committed to promoting and supporting fundamental human rights at our facilities, and have adopted a Human Rights Policy. In that policy, we prohibit the use of child labor and all forms of forced labor, including prison labor, indentured labor, bonded labor, military labor, modern forms of slavery, and any form of human trafficking. Health and Safety. Our goal is to send each employee home safe at the end of the day. As such, safety is at the central core of our culture, and is infused at every level of our organization. More than just policy and procedure, our safety program gives equal focus to the human side of safety, integrating coaching and mentoring efforts with compliance-driven approaches. By instilling a deep commitment to safety that reaches from our Chief Executive Officer to our general laborers, we have achieved industry-leading safety performance. Over the last four years, our average total recordable incident rate was 2.35 and our average days away rate was 0.51, calculated in accordance with the Occupational Safety and Health Administration’s record keeping requirements. Each of our facilities utilize various interactions to achieve this performance, from a toolbox meeting to cover the day’s work and any particular safety concern, to monthly Safety Plan Meetings, ‘No Days Away’ Safety Awards, and our employee-favorite, Safety Day. Each year, a facility may close for one full day to cover safety training and updates. Outside vendors demonstrate the latest safety procedures and equipment in a hands-on, fun atmosphere. As a manufacturer, we work hard to eliminate hazards associated with high-risk work and have measures in place that include programs for fall protection, heavy equipment operation, and lockout/tagout. We also focus on personal safety issues, such as complacency and fatigue. We offer our employees medical, dental, and vision insurance coverage to support their physical and mental well-being. We seek to keep our employees healthy during the COVID‑19 pandemic by taking proactive and precautionary steps to ensure the safety of our employees including frequent cleaning and disinfection of workspaces, providing personal protective equipment, instituting social distancing measure, staggering employee schedules, offering remote working environments for certain employees, encouraging vaccination, and guiding employees on preemptive measures as outlined by the Center for Disease Control (CDC). Diversity and Inclusion. Diversity and inclusion are integral to our employee experience, and we are proud of our diverse workforce. Companies that are diverse in age, gender identity, race, sexual orientation, physical or mental ability, ethnicity, and perspective are shown to be more resilient. We believe that diversity and inclusion are important in building the most effective, high-performing teams as part of our ACT culture. As of December 31, 2022, 51% of our employees in the United States self-identified as belonging to one or more of the following racial/ethnic groups: American Indian or Alaskan Native, African American/Black, Asian, Hispanic or Latino, and Native Hawaiian or other Pacific Islander. As of December 31, 2022, 12% of our employees self- identified as female. Our goal is to build a skilled and strong workforce that is not only diverse in race and ethnicity, but also diverse in age, gender identity, sexual orientation, physical or mental ability, and perspective. Our Affirmative Action Program (“AAP”) strives to hire, recruit, train, and promote employees in job classifications without regard to race, age, religion, color, sex, national origin, physical or mental disability, marital or veteran status, sexual orientation, gender identity, or any other classification protected by law. To support these efforts, the AAP for our facilities in the United States is reviewed annually by a third-party consultant, establishing annual hiring goals for women, minorities, veterans, and individuals with disabilities. Ethics and Compliance. We take pride in the high standards of conduct that identifies us as a company. We have controls in place relating to compliance with our Code of Business Conduct and Ethics (“Code”), including a requirement for employees to review and understand the requirements of our Code, as well as an established whistleblower hotline and related procedures. Our Code, along with other key governance policies, is published on our website. We conduct training on our Code upon hire, and in regular intervals during the employee’s life cycle with us. The most recent ethics training for all salaried employees was launched in the fourth quarter of 2022. We also conduct anti-trust training annually. The most recent anti-trust training for certain senior management and sales employees was the first quarter of 2023. In addition, we recently conducted our “Respect in the Workplace” training which focused on inclusion, communication, and attentiveness to workplace behaviors and their impact on others. 9 Table of Contents Cybersecurity Cybersecurity is a top priority, and our program is driven by our commitment to maintaining a strong security architecture, active governance, and robust controls. Our program is led by our Director of Information Technology, who works closely with our senior management team to advance our cybersecurity strategy. The Audit Committee of our Board of Directors receives quarterly updates regarding information about cyber risk mitigation strategies, proposed plans of action to strengthen our architecture against evolving risks, as well as the identification of known cybersecurity breaches, in the event applicable. We do not believe our systems were breached in 2022. We maintain an incident response plan in the event of a cybersecurity incident, for the purpose of contacting authorities and informing key stakeholders. The principles of our program align with the National Institute of Standards and Technology’s five phase Cybersecurity Framework to identify, protect, detect, respond, and recover. Further, we use industry leading security tools, continuously monitor our networking architecture, conduct simulated attacks, and require employee training. Information About Our Executive Officers Information about our executive officers is set forth under the caption “Directors, Executive Officers, Promoters and Control Persons” in Part III — Item 10. “Directors, Executive Officers and Corporate Governance” of this 2022 Form 10‑K and is incorporated herein by reference.

Item 1A. Risk Factors You should carefully consider the following factors, together with all the other information included in this 2022 Form 10‑K, in evaluating our company and our business. If any of the following risks actually occur, our business, financial condition, results of operations, or cash flows could be materially and adversely affected, and the value of our stock could decline. The risks and uncertainties described below are those that we currently believe may materially affect our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. As such, you should not consider this list to be a complete statement of all potential risks or uncertainties. Risk Factor Summary This risk factor summary contains a high-level overview of certain of the principal factors and uncertainties that make an investment in our securities risky, including risks related to our industry and end markets, our business, our supply chain and production process, our financial condition, our internal control over financial reporting, and our common stock. The following summary is not complete and should be read together with the more detailed discussion of these and the other factors and uncertainties that follows before making an investment decision regarding our securities. The principal factors and uncertainties that makes an investment in our securities risky include the following. 10 Table of Contents Risks Related to Our Industry and End Markets • • • • Project delays in public water transmission projects could adversely affect our business; A downturn in government spending related to public water transmission projects could adversely affect our business; Our Engineered Steel Pressure Pipe segment faces an overcapacity situation due to recent capacity expansions as well as the potential for increased competition from substitute products from manufacturers of concrete pressure pipe, ductile iron, polyvinyl chloride (“PVC”), and high- density polyethylene pipe; The success of our business is affected by general and local economic conditions, and our business may be adversely affected by an economic slowdown or recession, or an inability of our pricing to keep pace with inflation of input costs; and • We are subject to stringent environmental, health, and safety laws, which may require us to incur substantial compliance and remediation costs, thereby reducing our profits.

Risks Related to Our Industry and End Markets Project delays in public water transmission projects could adversely affect our business. The public water agencies constructing water transmission projects generally announce the projects well in advance of the bidding and construction process. It is not unusual for SPP projects to be delayed and rescheduled. Projects are delayed and rescheduled for a number of reasons, including changes in project priorities, difficulties in complying with environmental and other government regulations, changes in ability to obtain adequate project funding, and additional time required to acquire rights-of- way or property rights. Delays in public water transmission projects may occur with insufficient notice to allow us to replace those projects in our manufacturing schedules. As a result, our business, financial position, results of operations, or cash flows may be adversely affected by unplanned downtime or reductions to facility utilization levels. A downturn in government spending related to public water transmission projects could adversely affect our business. Our business is primarily dependent upon spending on public water transmission projects, including water infrastructure upgrades, repairs, and replacement and new water infrastructure spending, which in turn depends on, among other things: • • • • the need for new or replacement infrastructure; the priorities placed on various projects by governmental entities; federal, state, and local government spending levels, including budgetary constraints related to capital projects and the ability to obtain financing; and the ability of governmental entities to obtain environmental approvals, right-of-way permits, and other required approvals and permits. Decreases in the number of, or government funding of, public water transmission projects could adversely affect our business, financial position, results of operations, or cash flows. Our Engineered Steel Pressure Pipe segment faces an overcapacity situation due to recent capacity expansions as well as the potential for increased competition from substitute products from manufacturers of concrete pressure pipe, ductile iron, polyvinyl chloride, and high-density polyethylene pipe. Most SPP projects are competitively bid and price competition can be vigorous. In a market that already has overcapacity issues, recent increases in capacity have negatively affected our sales, gross margins, and overall profitability. Other competitive factors include timely delivery, ability to meet customized specifications, and high freight costs. Although our SPP manufacturing facilities in Oregon, California, West Virginia, Texas, Missouri, and Mexico allow us to compete throughout North America, our competitors could build new facilities or expand capacity within our market areas. In 2019, a competitor broke ground on a new spiral welded steel pipe facility in Texas that became operational in the first half of 2021. New or expanded facilities or new competitors could have a material adverse effect on our market share, product pricing, sales, gross margins, and overall profitability in our business. Water transmission pipe is manufactured generally from steel, concrete, ductile iron, PVC, or HDPE. Each pipe material has advantages and disadvantages. Steel and concrete are more common materials for larger-diameter water transmission pipelines because ductile iron pipe generally is limited in diameter due to the manufacturing process. The public agencies and engineers who determine the specifications for water transmission projects analyze these pipe materials for suitability for each project. Individual project circumstances normally dictate the preferred material. If we experience cost increases in raw materials, labor, and overhead specific to our industry or the location of our facilities, while competing products or companies do not experience similar changes, we could experience an adverse change in the demand, price, and profitability of our products, which could have a material adverse effect on our business, financial position, results of operations, or cash flows. The success of our business is affected by general and local economic conditions, and our business may be adversely affected by an economic slowdown or recession, or an inability of our pricing to keep pace with inflation of input costs. We are subject to national and regional economic conditions. These conditions include, but are not limited to, recession, inflation, interest rates, unemployment levels, the state of the housing market, and gasoline prices. These conditions and the economy in general could be affected by significant national or international events such as a global health crisis (like COVID‑19), acts of terrorism or acts of war (including the recent Russian invasion of Ukraine). 12 Table of Contents Periods of economic slowdown or recession in the United States, or the public perception that one may occur, have and could further decrease the demand for our products, affect the price of our products, and adversely impact our business. We have been impacted in the past by the general slowing of the economy, and the economic slowdown has had an adverse impact on our business, financial position, results of operations, or cash flows. Alternatively, our business may be adversely impacted by high inflation of input costs. We currently conduct a significant portion of our precast and reinforced concrete products business in Texas and Utah, which we estimate represented approximately 52% and 43%, respectively, of Precast net sales for the year ended December 31, 2022. Local economic conditions depend on a variety of factors, including national economic conditions, local and state budgets, infrastructure spending, and the impact of federal cutbacks. Any decrease in construction activity in Texas or Utah could have a material adverse effect on our business, financial condition, and results of operations. We are subject to stringent environmental, health, and safety laws, which may require us to incur substantial compliance and remediation costs, thereby reducing our profits. We are subject to many federal, state, local, and foreign environmental, health, and safety laws and regulations, particularly with respect to the use, handling, treatment, storage, discharge, and disposal of substances and hazardous wastes used or generated in our manufacturing processes. Compliance with these laws and regulations is a significant factor in our business. We have incurred, and expect to continue to incur, significant expenditures to comply with applicable environmental laws and regulations. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment, or remedial actions. We are currently, and may in the future be, required to incur costs relating to the environmental assessment or environmental remediation of our property, and for addressing environmental conditions, including, but not limited to, the issues associated with our Portland, Oregon facility as discussed in Note 15 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Some environmental laws and regulations impose liability and responsibility on present and former owners, operators, or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination. Consequently, we cannot assure you that existing or future circumstances, the development of new facts, or the failure of third parties to address contamination at current or former facilities or properties will not require significant expenditures by us. We expect to continue to be subject to increasingly stringent environmental, health, and safety laws and regulations. It is difficult to predict the future interpretation and development of environmental, health, and safety laws and regulations or their impact on our future earnings and operations. We anticipate that compliance with these laws and regulations will continue to require capital expenditures and operating costs. Any increase in these costs, or unanticipated liabilities arising, for example, out of discovery of previously unknown conditions or more aggressive enforcement actions, could adversely affect our results of operations, and there is no assurance that they will not have a material adverse effect on our business, financial position, results of operations, or cash flows. Risks Related to Our Business We face risks in connection with the integration of recent or future potential acquisitions and divestitures. Acquiring businesses that expand and/or complement our operations has been an important element of our business strategy, and we continue to evaluate potential acquisitions that may expand and/or complement our business. We may not be able to successfully identify attractive acquisition candidates or negotiate favorable terms in the future. Furthermore, our ability to effectively integrate any future acquisitions will depend on, among other things, the adequacy of our implementation plans, the ability of our management to oversee and operate effectively the combined operations, and our ability to achieve desired operational efficiencies. We may face challenges in integrating cultures, information systems, and business processes and policies in a seamless manner that minimizes any adverse impact on customers, suppliers, employees, and other parties. Acquired businesses may have liabilities, adverse operating issues, or other matters of concern arise following the acquisition that we fail to discover through due diligence prior to the acquisition. Further, our acquisition targets may not have as robust internal controls over financial reporting as would be expected of a public company, and therefore could lead to potential internal control deficiencies or material weaknesses. Acquisitions may also result in the recording of goodwill and other intangible assets that are subject to potential impairment in the future that could harm our financial results. We may also consider other alternatives in order to strategically position our business and continue to compete in our markets, which may include joint ventures and/or divestitures. Our failure to successfully integrate the operations of any businesses that we may acquire in the future or our inability to attract a business partner in which to enter into a joint venture or a buyer willing to purchase our assets may adversely affect our business, financial position, results of operations, or cash flows. 13 Table of Contents We acquired ParkUSA on October 5, 2021 and Geneva on January 31, 2020. The success of these acquisitions depends, in part, on our ability to successfully integrate these businesses with our current operations and to realize the anticipated benefits, including synergies, from the acquisitions on a timely basis. It may take longer than expected to realize these anticipated benefits and they may ultimately be smaller than we expect. There are a number of challenges and risks involved in our ability to successfully integrate ParkUSA and Geneva with our current business and to realize the anticipated benefits of these acquisitions, including all of the risks identified in the previous paragraph. Material weaknesses in our internal control over financial reporting as of December 31, 2022 were identified in connection with the design and implementation of the enterprise resource planning (“ERP”) system implemented on August 1, 2022 at ParkUSA, as described in Part II — Item 9A, “Controls and Procedures” of this 2022 Form 10‑K. Any of these factors could have a material adverse effect on our business, financial condition, results of operations, or cash flows. The acquisitions of ParkUSA, Geneva, and acquisitions of other companies in the future could adversely affect operating results, dilute shareholders’ equity, or cause us to incur additional debt or assume contingent liabilities. To increase business, broaden the diversification of our products, or for other business or strategic reasons, we may acquire other companies in the future. For example, in October 2021, we acquired ParkUSA and in January 2020, we acquired Geneva. The acquisitions of ParkUSA and Geneva and any other acquisitions that we may enter into from time to time, involve a number of risks that could harm our business and result in ParkUSA, Geneva, and/or any other acquired business not performing as expected, including: • • • • • • • • • • • • problems integrating the acquired operations, personnel, technologies, or products with the existing business and products; failure to achieve cost savings or other financial or operating objectives with respect to an acquisition; possible adverse short-term effects on cash flows or operating results, and the use of cash and other resources for the acquisition that might affect liquidity, and that could have been used for other purposes; diversion of management’s time and attention from our existing business to the acquired business; potential failure to retain key technical, management, sales, and other personnel of the acquired business; difficulties in retaining relationships with suppliers and customers of the acquired business, particularly where such customers or suppliers compete with us; difficulties in the integration of financial reporting systems, which could cause a delay in the issuance of, or impact the reliability of the consolidated financial statements; failure to comply with Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”), including a delay in or failure to successfully integrate these businesses into our internal control over financial reporting, such as the material weaknesses in our internal control over financial reporting as of December 31, 2022 identified in connection with the design and implementation of the ERP system implemented on August 1, 2022 at ParkUSA, as described in Part II — Item 9A, “Controls and Procedures” of this 2022 Form 10‑K; insufficient experience with technologies and markets in which the acquired business is involved, which may be necessary to successfully operate and integrate the business; subsequent impairment of goodwill and acquired long-lived assets, including intangible assets; failure to achieve the expected return on investment for capital deployed to the organic growth strategies associated with prior acquisitions; and assumption of liabilities including, but not limited to, lawsuits, environmental liabilities, regulatory liabilities, tax examinations, and warranty issues. We may enter into acquisitions that are dilutive to earnings per share or that adversely impact margins as a whole. In addition, acquisitions could require investment of significant financial resources and require us to obtain additional equity financing, which may dilute shareholders’ equity, or require us to incur indebtedness. Our quarterly results of operations are subject to significant fluctuation. Our net sales and operating results may fluctuate significantly from quarter to quarter due to a number of factors, including: • • • • • • • the commencement, completion, or termination of contracts during any particular quarter; unplanned down time due to project delays or mechanical failure; underutilized capacity or facility productivity; adverse weather conditions; fluctuations in the cost of raw materials; disruptions in our supply chain; and competitive pressures. Results of operations in any period are not indicative of results for any future period, and comparisons between any two periods may not be meaningful. 14 Table of Contents Operating problems in our business could adversely affect our business, financial position, results of operations, or cash flows. Our manufacturing operations are subject to typical hazards and risks relating to the manufacture of similar products such as: explosions, fires, inclement weather, and natural disasters; • • mechanical failure; • • • • • • • • • unscheduled downtime; labor shortages; loss of process control and quality; disruptions to supply; raw materials quality defects; service provider delays or failures; transportation delays or failures; an inability to obtain or maintain required licenses or permits; and environmental hazards such as chemical spills, discharges, or releases of toxic or hazardous substances or gases into the environment or workplace. The occurrence of any of these operating problems at our facilities may have a material adverse effect on the productivity and profitability of a particular manufacturing facility or on our operations as a whole, during and after the period of these operating difficulties. For example, as discussed in Note 15 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K, on April 21, 2019, there was an accidental fire at our Saginaw, Texas facility which resulted in damage to the coatings building. There were no injuries, but the ability to coat at this facility was impaired while we repaired the damage. The operating problems listed above may also cause personal injury and loss of life, severe damage to or destruction of property and equipment, and environmental damage. In addition, individuals could seek damages for alleged personal injury or property damage. Furthermore, we could be subject to present and future claims with respect to workplace injury, exposure to hazardous materials, workers’ compensation, and other matters. Although we maintain property and casualty insurance of the types and in the amounts that we believe are customary for our industries, we cannot assure you that our insurance coverage will be adequate for liability that may be ultimately incurred or that such coverage will continue to be available to us on commercially reasonable terms. Any claims that result in liability exceeding our insurance coverage could have an adverse effect on our business, financial position, results of operations, or cash flows. We may be unable to develop or successfully market new products or our products might not obtain necessary approvals or achieve market acceptance, which could adversely affect our growth. We will continue to actively seek to develop new products and to expand our existing products into new markets, but we cannot assure you that we will be successful in these efforts. If we are unsuccessful in developing and marketing new products, expanding into new markets, or we do not obtain or maintain requisite approvals for our products, the demand for our products could be adversely affected, which could adversely affect our business, financial position, results of operations, or cash flows. Our recognition of revenue over time includes estimates. SPP revenue for water infrastructure steel pipe products is recognized over time as the manufacturing process progresses, and is measured by the costs incurred to date relative to the estimated total direct costs to fulfill each contract (cost-to- cost method). Estimated total costs of each contract are reviewed on a monthly basis by project management and operations personnel for all active projects. All cost revisions that result in a material change in gross profit are reviewed by senior management personnel. Significant judgment is required in estimating total costs and measuring the progress of project completion, as well as whether a loss is expected to be incurred on the contract. Changes in job performance, job conditions, and estimated profitability, including those arising from contract change orders, contract penalty provisions, foreign currency exchange rate movements, changes in raw materials costs, and final contract settlements may result in revisions to estimates of revenue, costs, and income, and are recognized in the period in which the revisions are determined. Due to the variability of events affecting our estimates which have a material impact on our contract accounting, actual results could differ from those estimates, which could adversely affect our financial position, results of operations, or cash flows. 15 Table of Contents We have a foreign operation which exposes us to the risks of doing business abroad. Our facility in San Luis Río Colorado, Mexico primarily exports products to the United States. We may operate in additional countries in the future. Any material changes in the quotas, regulations, tariffs, or duties on imports imposed by the United States government and our agencies, or on exports imposed by these foreign governments and their agencies could adversely affect our foreign operations. We also sell some of our products internationally, most often into Canada. Our foreign activities are also subject to various other risks of doing business in a foreign country, including: • • • • • • • • • currency fluctuations; the imposition of duties, tariffs, and other trade barriers; transportation delays and interruptions; political, social, and economic instability and disruptions; government embargoes or foreign trade restrictions; import and export controls; labor unrest and current and changing regulatory environments; limitations on our ability to enforce legal rights and remedies; and potentially adverse tax consequences. No assurance can be given that our operations may not be adversely affected in the future. Any of these events could have an adverse effect on our operations in the future by reducing the demand for our products and services, decreasing the prices at which we can sell our products, or increasing costs such that there could be an adverse effect on our business, financial position, results of operations, or cash flows. We cannot assure you that we will continue to operate in compliance with applicable customs, currency exchange control regulations, transfer pricing regulations, or any other laws or regulations to which we may be subject, or that any such regulations or laws will not be modified. Any failure by us to comply with any such applicable regulations or laws, or any changes in any such regulations or laws could have a material adverse effect on our business, financial position, results of operations, or cash flows. Our Engineered Steel Pressure Pipe backlog is subject to reduction and cancelation. Backlog, which represents the balance of remaining performance obligations under signed contracts for SPP water infrastructure steel pipe products for which revenue is recognized over time, was approximately $274 million as of December 31, 2022. Our backlog is subject to fluctuations; moreover, cancelations of purchase orders, change orders on contracts, or reductions of product quantities could materially reduce our backlog and, consequently, future revenues. Our failure to replace canceled or reduced backlog could result in lower revenues, which could adversely affect our business, financial position, results of operations, or cash flows. The COVID‑19 pandemic may have an adverse impact on our business. The impacts of the COVID‑19 pandemic, and the resurgence of new COVID‑19 virus variants, on global and domestic economic conditions, including the impacts of labor and raw material shortages, the long-term potential to reduce or delay funding of municipal projects, and the continued disruptions to and volatility in the financial markets remain uncertain. While the COVID‑19 pandemic has caused various direct and indirect financial impacts associated with project bidding, execution, and product deliveries over the past couple of years, we remain unable to predict the ultimate impact that the COVID‑19 pandemic may have on our business, future results of operations, financial position, or cash flows. We continue to monitor the impact of the COVID‑19 pandemic on all aspects of our business. The impacts of the COVID‑19 pandemic may also exacerbate other risks discussed in Part I – Item 1A. “Risk Factors” in this 2022 Form 10‑K, any of which could have a material effect on us. This situation is changing rapidly and additional impacts may arise that we are not aware of currently. The conflict in Ukraine may have an adverse impact on our business. On February 24, 2022, Russia invaded Ukraine. The invasion received widespread international condemnation and many countries, including the United States, imposed new sanctions. While the situation remains highly fluid and the outlook is subject to extraordinary uncertainty, the crisis has already resulted in economic consequences. Energy and commodity prices have surged, adding to inflationary pressures from supply chain disruptions and the rebound from the COVID‑19 pandemic. The sanctions on Russia have had a substantial impact on the global economy and financial markets, with significant spillovers to other countries. Should the conflict escalate, the economic damage may increase. We continue to monitor the impact of the crisis in Ukraine on all aspects of our business, including how it will impact our employees, customers, supply chain, and distribution network. Impacts include financial and commodity volatility in raw material and other input costs and availability, as well as volatility in the financial markets. The severity of impacts on the global economy and our business, results of operations, financial position and cash flows remain unknown. 16 Table of Contents Climate change and related regulatory requirements present an ongoing risk to our business operations. The rise in average global temperatures has resulted in elevated levels of carbon dioxide and other greenhouse gases in the atmosphere, altering long-term weather patterns that lead to an increased frequency and severity of natural disasters. Severe weather conditions could potentially disrupt our manufacturing and construction activities; areas prone to flooding could face delays resulting in lost production and extreme heat could threaten the health and well-being of our employees. Given the changes in weather patterns brought on by climate change, essentially all of our facilities are vulnerable to extreme conditions and natural disasters, increasing the risk of damage to our facilities and products. Those risks could also hinder our supply chain processes and limit our access to raw materials or our ability to fulfill orders for customers. Evolving governmental regulations to combat climate change risks would likely increase our costs for items including energy and transportation, which may prove disproportional to similar increases in costs experienced by competitors. We anticipate heightened regulatory focus in the near future and failure to comply with new environmental regulations and policies could result in reputational damage with our stakeholders, resulting in decreased demand for our products and lower than expected revenue. Risks Related to Our Supply Chain and Production Process Our business may be adversely impacted by staffing shortages, other labor matters, and work stoppages. Current nationwide staffing shortages have impacted our ability to attract both skilled and unskilled workers needed for our manufacturing operations, and the inability to fully staff any one of our facilities may impact our ability to work on projects and, as a result, could have a material adverse effect on our business, financial position, results of operations, or cash flows. A work stoppage or other limitation on production could occur at our facilities or our suppliers’ facilities for any number of reasons, including as a result of absenteeism, public health issues (i.e. COVID‑19), labor issues, including disputes under our existing collective bargaining agreement or in connection with negotiation of new collective bargaining agreements, or for other reasons. As of December 31, 2022, we had approximately 62 employees that were represented by a single labor union. Although we believe that our relations with our employees and the labor union are good, no assurances can be made that we will not experience conflicts with the labor union, other groups representing employees, or our employees in general, especially in the context of any future negotiations with the labor union. We can also make no assurance that future negotiations with the labor union will not result in a significant increase in the cost of labor. Additionally, the employees of some of our customers are unionized. Any strikes, other labor matters, or work stoppages experienced by our customers may impact our ability to work on projects and, as a result, have an adverse effect on our business, financial position, results of operations, or cash flows. Fluctuations in steel prices and availability may affect our future results of operations. Purchased steel represents a substantial portion of SPP cost of sales. The steel industry is highly cyclical in nature, and at times, pricing can be highly volatile due to a number of factors beyond our control, including general economic conditions, import duties, other trade restrictions, and currency exchange rates. Over the past three years, steel prices have fluctuated significantly. Our average cost for a ton of steel was approximately $1,174 per ton in 2022, $1,291 per ton in 2021, and $655 per ton in 2020. In 2022, our monthly average steel purchasing costs ranged from a high of approximately $1,782 per ton to a low of approximately $906 per ton. This volatility can significantly affect our gross profit. Although we seek to recover increases in steel prices through price increases in our products, we have not always been successful. Any increase in steel prices that is not offset by an increase in our prices could have an adverse effect on our business, financial position, results of operations, or cash flows. In addition, if we are unable to acquire timely steel supplies, we may need to decline project bidding opportunities, which could also have an adverse effect on our business, financial position, results of operations, or cash flows. We may be subject to claims for damages for defective products, which could adversely affect our business, financial position, results of operations, or cash flows. We warrant our products to be free of certain defects. We have, from time to time, had claims alleging defects in our products. We cannot assure you that we will not experience material product liability losses in the future or that we will not incur significant costs to defend such claims. While we currently have product liability insurance, we cannot assure you that our product liability insurance coverage will be adequate for liabilities that may be incurred in the future or that such coverage will continue to be available to us on commercially reasonable terms. Any claims relating to defective products that result in liabilities exceeding our insurance coverage could have an adverse effect on our business, financial position, results of operations, or cash flows. We may not be able to recover costs and damages from vendors that supply defective materials. We may receive defective materials from our vendors that are incorporated into our products during the manufacturing process. The cost to repair, remake, or replace defective products could be greater than the amount that can be recovered from the vendor, in addition to creating inefficiencies in our production scheduling. Such excess costs could have an adverse effect on our business, financial position, results of operations, or cash flows. 17 Table of Contents Our information technology systems can be negatively affected by cybersecurity threats. Increased global information technology security requirements, vulnerabilities, threats, and a rise in sophisticated and targeted computer crime pose a risk to the security of our systems, networks, and the confidentiality, availability, and integrity of our data. Despite our efforts to protect sensitive information and confidential and personal data, our facilities and systems and those of our third-party service providers may be vulnerable to security breaches. This could lead to disclosure, modification, or destruction of proprietary, employee, and other key information and operational disruptions, which in turn could adversely affect our reputation and competitiveness in our markets. To the extent that any disruption or security breach results in a loss or damage to our data, or an inappropriate disclosure of confidential or protected personal information, it could cause significant damage to our reputation, affect our relationships with our customers, suppliers, and employees, lead to claims against us, and ultimately harm our business. Additionally, we may be required to incur significant costs to protect against damage caused by these disruptions or security breaches in the future. Any of the foregoing factors could have an adverse effect on our business, financial position, results of operations, or cash flows. Risks Related to Our Financial Condition We will need to substantially increase working capital if market conditions and customer order levels continue to grow. If market conditions and SPP customer order levels were to dramatically increase, we would have to increase our working capital substantially, as it takes several months for project production to be translated into cash receipts. In general, revolving loan borrowings and letters of credit under the Credit Agreement dated June 30, 2021 with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent, and the lenders from time to time party thereto, including the initial sole lender, Wells Fargo (the “Lenders”), as amended by the Incremental Amendment dated October 22, 2021 and the Second Amendment to Credit Agreement dated April 29, 2022 (together, the “Amended Credit Agreement”), are limited to the aggregate amount of $125 million. As of December 31, 2022 under the Amended Credit Agreement, we had $83.7 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $40 million. We may not have sufficient availability under the Amended Credit Agreement to borrow the amounts we need, and other opportunities to borrow additional funds or raise capital in the equity markets may be limited or nonexistent. A shortage in the availability of working capital could have a material adverse effect on our business, financial condition, results of operations, or cash flows. Our debt obligations could have a material adverse effect on our business, financial condition, results of operations, or cash flows. We have financed our operations through cash flows from operations, available borrowings, and other financing arrangements. As of December 31, 2022, we had $83.7 million of outstanding revolving loan borrowings, $10.8 million of current debt, $94.2 million of operating lease liabilities, and $3.0 million of finance lease liabilities. We could incur additional revolving loan borrowings under the Amended Credit Agreement in the future to finance increases in working capital, finance mergers, acquisitions, and capital expenditures, fund negative operating cash flows, or for other corporate purposes. These borrowings could become significant in the future. Our current and future debt and debt service obligations could: • • • • • • limit our ability to obtain additional financing for working capital or other purposes in the future; reduce the amount of funds available to finance our operations, capital expenditures, and other activities; increase our vulnerability to economic downturns, illiquid capital markets, and adverse industry conditions; limit our flexibility in responding to changing business and economic conditions, including increased competition; place us at a disadvantage when compared to our competitors that have less debt; and with respect to our borrowings that bear interest at variable rates, cause us to be vulnerable to increases in interest rates. Our ability to make scheduled payments on our current and future debt will depend on our future operating performance and cash flows, which are subject to prevailing economic conditions, prevailing interest rate levels, and other financial, competitive, and business factors, many of which are beyond our control. Our inability to make scheduled payments on our debt or any of the foregoing factors could have a material adverse effect on our business, financial condition, results of operations, or cash flows. To the extent we have not hedged against rising interest rates, an increase in the applicable benchmark interest rates would increase our cost of servicing our indebtedness and could have a material adverse effect on our business, financial condition, results of operations, or cash flows. 18 Table of Contents A portion of our indebtedness is subject to interest rate risk, which could cause our debt service obligations to increase significantly. Borrowings under the Amended Credit Agreement and our current debt are, and additional borrowings in the future may be, at variable rates of interest that expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed will remain the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. We have, and may in the future enter into additional, interest rate swaps for a portion of our variable rate debt whereby we exchange floating for fixed rate interest payments in order to reduce exposure to interest rate volatility. However, any interest rate swaps into which we enter may not fully mitigate our interest rate risk. Our failure to comply with covenants in our debt agreements could result in our indebtedness being immediately due and payable, which could have a material adverse effect on our business, financial condition, results of operations, or cash flows. The agreements governing our debt include covenants that impose certain requirements with respect to our financial condition and results of operations and general business activities. These covenants place restrictions on, among other things, our ability to incur certain additional debt and to create liens or other encumbrances on assets. In addition, our obligations under the Amended Credit Agreement are secured by a senior security interest in substantially all of our and our subsidiaries’ assets. Our ability to comply with the covenants under our debt instruments in the future is uncertain and will be affected by our results of operations and financial condition as well as other events and circumstances beyond our control. If market and other economic conditions deteriorate, our ability to comply with these covenants may be impaired. A failure to comply with the requirements of these covenants, if not waived or cured, could permit acceleration of the related debt. If any of our debt is accelerated, we cannot assure you that we would have sufficient assets to repay such debt or that we would be able to refinance such debt on commercially reasonable terms or at all. The acceleration of a significant portion of our current and future debt could have a material adverse effect on our business, financial condition, results of operations, or cash flows. Disruptions in the financial markets, including the banking industry, and a general economic slowdown could cause us to be unable to obtain financing or receive customer payments and expose us to risks related to the overall macro-economic environment, which could have a material adverse effect on our business, financial condition, results of operations, or cash flows. The United States equity and credit markets, as well as certain financial institutions, have experienced significant price volatility, dislocations, and liquidity disruptions, which have caused market prices of many equities to fluctuate substantially, the spreads on prospective debt financings to widen considerably, and disruptions in select banking transactions. These circumstances have materially impacted liquidity in the financial markets, making terms for certain financings less attractive, and in some cases have resulted in the unavailability of financing, even for companies who are otherwise qualified to obtain financing. These events may make it less likely that we will be able to obtain additional financing, may make it more difficult or prohibitively costly for us to raise capital through the issuance of debt or equity securities, which may prove necessary to execute our growth strategies, and may impact our customers and their ability to make payments or obtain credit. Risks Related to Our Internal Control Over Financial Reporting Our Audit Committee and management have identified a material weakness in our internal controls over financial reporting, and we may be unable to develop, implement, and maintain appropriate controls in future periods. The Sarbanes-Oxley Act and SEC rules require that management report annually on the effectiveness of our internal control over financial reporting and our disclosure controls and procedures. Among other things, management must conduct an assessment of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm to audit, the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Based on our management’s assessment, we believe that, as of December 31, 2022, our internal controls over financial reporting were not effective. The specific material weakness is described in Part II — Item 9A, “Controls and Procedures” of this 2022 Form 10‑K in “Management’s Report on Internal Control over Financial Reporting”. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements would not be prevented or detected. We have adopted a remediation plan to address the material weakness identified. The implementation and administration of the remediation plan may divert the attention of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as well as other senior members of our management team, away from the operations of our business until the material weakness in our internal control is considered remediated. 19 Table of Contents The material weakness in our internal control over financial reporting as of December 31, 2022 was attributed to control deficiencies in the ERP system implementation project at ParkUSA and resultant business process control deficiencies. We cannot assure you that additional material weaknesses in our internal control over financial reporting will not be identified in the future. Any failure to maintain or implement required new or improved controls, or any difficulties we encounter in their implementation, could result in additional material weaknesses, and create a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis. This could cause us to fail to meet our reporting obligations or cause investors to lose confidence in our reported financial information, leading to a decline in our stock price. Further and continued determinations that there are material weaknesses in the effectiveness of our internal controls could also reduce our ability to obtain financing or could increase the cost of any financing we obtain and require additional expenditures of both money and management’s time to comply with applicable requirements. For more information relating to our internal control over financial reporting and disclosure controls and procedures, see Part II — Item 9A, “Controls and Procedures” of this 2022 Form 10‑K. Risks Related to Our Common Stock The relatively low trading volume of our common stock may limit your ability to sell your shares. Although our shares of common stock are listed on the Nasdaq Global Select Market, we have historically experienced a relatively low trading volume. If we have a low trading volume in the future, holders of our shares may have difficulty selling a large number of shares of our common stock in the manner or at a price that might otherwise be attainable. The market price of our common stock could be subject to significant fluctuations. The market price of our common stock has experienced, and may continue to experience, significant volatility. Among the factors that could affect our stock price are: • • • • • • • • • • our operating and financial performance and prospects; quarterly variations in the rate of growth of our financial indicators, such as earnings per share, net income, and net sales; changes in revenue or earnings estimates or publication of research reports by analysts; loss of any member of our senior management team; speculation in the press or investment community; strategic actions by us or our competitors, such as acquisitions or restructuring; sales of our common stock by shareholders; relatively low trading volume; general market conditions and market expectations for our industry and the financial health of our customers; and domestic and international economic, legal, and regulatory factors unrelated to our performance. The stock markets in general have experienced broad fluctuations that have often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. Certain provisions of our governing documents and Oregon law could discourage potential acquisition proposals. Our articles of incorporation contain provisions that: • • • classify the board of directors into three classes, each of which serves for a three-year term with one class elected each year; provide that directors may be removed by shareholders only for cause and only upon the affirmative vote of 75% of the outstanding shares of common stock; and permit the board of directors to issue preferred stock in one or more series, fix the number of shares constituting any such series, and determine the voting powers and all other rights and preferences of any such series, without any further vote or action by our shareholders. In addition, we are subject to certain provisions of the Oregon Business Corporation Act that could discourage potential acquisition proposals, could deter, delay, or prevent a change in control that our shareholders consider favorable, and could depress the market value of our common stock. Additional information regarding the above described provisions of our governing documents and the Oregon Business Corporation Act is set forth in the “Description of Securities Registered Under Section 12 of the Securities Exchange Act of 1934” filed as Exhibit 4.2 to our 2019 Form 10‑K, which was filed with the SEC on March 3, 2020. Item 1B. Unresolved Staff Comments None. 20 Table of Contents Item 2. Properties Our facilities serve regional markets, which vary in the number and sizes of projects year-over-year. Consequently, we have excess manufacturing capacity from time to time at each of our facilities. We believe the quality and productive capacity of our facilities are sufficient to maintain our competitive position for the foreseeable future.

See Note 15 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Item 4. Mine Safety Disclosures Not applicable. 21 Table of Contents PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information Our common stock is quoted on the Nasdaq Global Select Market under the symbol “NWPX.” There were 18 shareholders of record as of March 6, 2023. A substantially greater number of holders of our common stock are beneficial holders, whose shares are held of record by banks, brokers, and other financial institutions. We do not intend to pay cash dividends in the foreseeable future. We have not issued any securities during the past three years that were not registered under the Securities Act. On November 3, 2020, our shelf registration statement on Form S‑3 (Registration No. 333‑249637) covering the potential future sale of up to $150 million of our equity and/or debt securities or combinations thereof, was declared effective by the SEC. This shelf registration statement provides another potential source of capital, in addition to other alternatives already in place. We cannot be certain that funding will be available on favorable terms or available at all. To the extent that we raise additional funds by issuing equity securities, our shareholders may experience significant dilution. As of the date of this 2022 Form 10‑K, we have not yet sold any securities under this shelf registration statement, nor do we have an obligation to do so. Please refer to the factors discussed in Part I — Item 1A. “Risk Factors” of this 2022 Form 10‑K. On September 2, 2022, we entered into an Open Market Sale Agreement (the “At-the-Market Offering”) with Jefferies LLC (“Jefferies”), pursuant to which we may issue and sell shares of our common stock, par value $0.01 per share, having aggregate offering sales proceeds of up to $50 million (the “Shares”) from time to time through Jefferies as our sales agent. We may sell the Shares in amounts and at times to be determined by us from time to time subject to the terms and conditions of the At-the-Market Offering, but we have no obligation to sell any of the Shares under the At-the-Market Offering. The Shares to be sold under the At-the-Market Offering, if any, will be offered and sold pursuant to our shelf registration statement on Form S‑3 discussed above, and the prospectus supplement dated September 2, 2022 filed by us. We will pay Jefferies a cash commission of up to 3.0% of gross proceeds from the sale of the Shares pursuant to the At-the-Market Offering. We have also agreed to provide Jefferies with customary indemnification and contribution rights. No proceeds were raised under the At-the-Market Offering during the year ended December 31, 2022.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following is management’s discussion and analysis of certain significant factors that have affected our consolidated financial condition and results of operations during the periods included herein. This discussion should be read in conjunction with our historical Consolidated Financial Statements and Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under Part I — Item 1A. “Risk Factors” or in other parts of this 2022 Form 10‑K. For discussion related to the results of operations and changes in financial condition for the year ended December 31, 2021 compared to the year ended December 31, 2020, refer to Part II — Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Year Ended December 31, 2021 Compared to Year Ended December 31, 2020” and “Liquidity and Capital Resources” in our 2021 Form 10‑K, which was filed with the SEC on March 16, 2022, and which is incorporated herein by reference. Overview Northwest Pipe Company is a leading manufacturer of water-related infrastructure products, and operates in two segments, Engineered Steel Pressure Pipe (SPP) and Precast Infrastructure and Engineered Systems (Precast). For detailed descriptions of these segments, see the “Our Segments” discussion in Part I — Item 1. “Business” of this 2022 Form 10‑K. In addition to being the largest manufacturer of engineered steel water pipeline systems in North America, we manufacture stormwater and wastewater technology products; high-quality precast and reinforced concrete products; pump lift stations; steel casing pipe, bar-wrapped concrete cylinder pipe, and one of the largest offerings of pipeline system joints, fittings, and specialized components. Strategically positioned to meet growing water and wastewater infrastructure needs, we provide solution-based products for a wide range of markets under the ParkUSA, Geneva Pipe and Precast, Permalok®, and Northwest Pipe Company lines. Our diverse team is committed to quality and innovation while demonstrating our core values of accountability, commitment, and teamwork. We are headquartered in Vancouver, Washington, and have 13 manufacturing facilities across North America. Our water infrastructure products are sold generally to installation contractors, who include our products in their bids to federal, state, and municipal agencies, privately-owned water companies, or developers for specific projects. We believe our sales are substantially driven by spending on urban growth and new water infrastructure with a recent trend towards spending on water infrastructure replacement, repair, and upgrade. Within the total range of products, our steel pipe tends to fit the larger-diameter, higher-pressure pipeline applications, while our precast concrete products mainly serve stormwater and sanitary sewer systems. Our Current Economic Environment Demand for our Precast products is generally influenced by general economic conditions such as housing starts, population growth, interest rates, and rates of inflation. According to the United States Census Bureau, privately-owned housing starts in December 2022 were at a seasonally adjusted annual rate of 1.4 million, compared to a seasonally adjusted annual rate of 1.8 million in December 2021, and the population of the United States is expected to increase by approximately 2 million people in 2023. Additionally, while recent and anticipated future increases in the federal funds rate by the Federal Reserve are expected to temper demand for housing, the immediate impacts have been muted by the demand for housing, stymied by recent labor and commodity shortages currently limiting the supply of new homes. Our SPP projects are often planned for many years in advance, as we operate that business with a long-term time horizon for which the projects are sometimes part of 50‑year build-out plans. Long-term demand for water infrastructure projects in the United States appears strong. Even though recent demand for engineered steel pressure pipe has improved, a shift to a recessionary economy could strain governmental and water agency budgets and financing which could impact prospects for our business in the medium term. Additionally, we have experienced effects of the current labor shortage at certain manufacturing facilities, for which we are mitigating the impact through the use of overtime and third-party outsourcing as warranted. It is possible that a prolonged shortage of qualified, available workers could have an adverse effect on our business. Purchased steel typically represents approximately 35% of cost of sales, and higher steel costs generally result in higher selling prices and revenue; however, volatile fluctuations in steel markets can affect our business. SPP contracts are generally quoted on a fixed-price basis, and volatile steel markets can result in selling prices that no longer correlate to the cost available at the time of steel purchase. Steel markets have remained volatile through 2022, with prices dropping significantly in the fourth quarter. The reduced steel costs have begun and will continue to be realized in our financial results. 24 Table of Contents Russia’s invasion of Ukraine is considered to be largely responsible for increased fuel costs, increasing our delivery costs. While these costs are generally passed along to the customer, there can be no assurance that all of these increased costs will be recouped, which could be material until world economic forces stabilize. Freight costs represent approximately 6% of cost of sales of our SPP business, for which the risk is more significant due to the long lead times between when an SPP contract is entered and the product is shipped. Implementation of Enterprise Resource Planning (ERP) System at ParkUSA In the third quarter of 2022, we implemented our ERP system at the ParkUSA manufacturing facilities. Due primarily to an underinvestment in systems preceding our acquisition, and vastly broader product offerings, this implementation has caused, and may continue to cause, disruption and inefficiencies in ParkUSA’s operations. Impact of the COVID‑19 Pandemic on Our Business While the COVID‑19 pandemic has caused various direct and indirect financial impacts associated with project bidding, execution, and product deliveries over the past couple of years, we remain unable to predict the ultimate impact that the COVID‑19 pandemic may have on our business, future results of operations, financial position, or cash flows. For additional details, refer to the information set forth under the caption “Impact of the COVID‑19 Pandemic on Our Business” in Part I — Item 1. “Business” and discussions in Part I — Item 1A. “Risk Factors” of this 2022 Form 10‑K. Results of Operations The following table sets forth, for the periods indicated, certain financial information regarding costs and expenses expressed in dollars (in thousands) and as a percentage of total net sales.

Net sales increased 37.3% to $457.7 million in 2022 compared to $333.3 million in 2021. SPP net sales increased 18.4% to $307.6 million in 2022 compared to $259.8 million in 2021 driven by a 20% increase in selling price per ton due to increased raw materials costs, partially offset by a 1% decrease in tons produced resulting from changes in project timing. Bidding activity, backlog, and production levels may vary significantly from period to period affecting sales volumes. Precast net sales increased 104.2% to $150.1 million in 2022 compared to $73.5 million in 2021 primarily due to the ParkUSA operations acquired in October 2021, which contributed $84.7 million and $18.0 million in net sales for 2022 and 2021, respectively. In addition, the segment realized a 17.9% increase in net sales at the pre-existing Precast operations due to a 45% increase in selling prices due to the high demand for our concrete products coupled with increased material costs, partially offset by an 18% decrease in volume shipped due to unscheduled equipment downtime and changes in product mix. Gross profit. Gross profit increased 94.0% to $85.9 million (18.8% of net sales) in 2022 compared to $44.3 million (13.3% of net sales) in 2021. SPP gross profit increased 42.2% to $44.5 million (14.5% of SPP net sales) in 2022 compared to $31.3 million (12.0% of SPP net sales) in 2021 due to improved product pricing. SPP gross profit in 2022 was reduced, in part, as a result of a $2.0 million product liability settlement reserve recorded in the first quarter. Precast gross profit increased 219.0% to $41.4 million (27.6% of Precast net sales) in 2022 compared to $13.0 million (17.7% of Precast net sales) in 2021 due to contributions from the ParkUSA operations, as well as improved pricing at the pre-existing Precast operations. Precast gross profit in 2021 was reduced by $2.3 million of acquisition-related fair value inventory charges. Selling, general, and administrative expense. Selling, general, and administrative expense increased 45.4% to $41.0 million (9.0% of net sales) in 2022 compared to $28.2 million (8.5% of net sales) in 2021. The increase in selling, general, and administrative expense was primarily due to the acquired ParkUSA operations, including $5.0 million in higher compensation-related expense and $2.3 million in higher amortization expense, partially offset by $3.3 million in lower acquisition-related transaction costs. We also incurred an additional $6.7 million in higher other compensation-related expense, $1.0 million in higher professional fees, and $0.7 million in higher travel expense. Income taxes. Income tax expense was $10.2 million in 2022 (an effective income tax rate of 24.7%) compared to $3.6 million in 2021 (an effective income tax rate of 24.0%). The effective income tax rate for 2022 was primarily impacted by non-deductible permanent differences. The effective income tax rate for 2021 was primarily impacted by estimated changes in our valuation allowance. The effective income tax rate can change significantly depending on the relationship of permanent income tax deductions and tax credits to estimated pre-tax income or loss and the changes in valuation allowances. Accordingly, the comparison of effective income tax rates between periods is not meaningful in all situations. Liquidity and Capital Resources Sources and Uses of Cash Our principal sources of liquidity generally include operating cash flows and the Amended Credit Agreement. From time to time our long-term capital needs may be met through the issuance of additional debt or equity. Our principal uses of liquidity generally include capital expenditures, working capital, organic growth initiatives, acquisitions, and debt service. Information regarding our cash flows for the years ended December 31, 2022, 2021, and 2020 are presented in our Consolidated Statements of Cash Flows contained in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K, and are further discussed below. As of December 31, 2022, our working capital (current assets minus current liabilities) was $187.9 million compared to $164.1 million as of December 31, 2021. Cash and cash equivalents totaled $3.7 million and $3.0 million as of December 31, 2022 and 2021, respectively. 26 Table of Contents Fluctuations in SPP working capital accounts result from timing differences between production, shipment, invoicing, and collection, as well as changes in levels of production and costs of materials. We typically have a relatively large investment in working capital, as we generally pay for materials, labor, and other production costs in the initial stages of a project, while payments from our customers are generally received after finished product is delivered. A portion of our revenues are recognized over time as the manufacturing process progresses; therefore, cash receipts typically occur subsequent to when revenue is recognized and the elapsed time between when revenue is recorded and when cash is received can be significant. As such, our payment cycle is a significantly shorter interval than our collection cycle, although the effect of this difference in the cycles may vary by project, and from period to period. As of December 31, 2022, we had $83.7 million of outstanding revolving loan borrowings, $10.8 million of outstanding current debt, $94.2 million of operating lease liabilities, and $3.0 million of finance lease liabilities. As of December 31, 2021, we had $86.8 million of outstanding revolving loan borrowings, $98.4 million of operating lease liabilities, and $2.2 million of finance lease liabilities. For future maturities of these obligations, see Notes 7, 8, and 9 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Due to the uncertainty with respect to the timing of future cash flows associated with our approximately $4.5 million in unrecognized tax benefits as of December 31, 2022, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. For further information, see Note 17 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Net Cash Provided by (Used in) Operating Activities Net cash provided by (used in) operating activities was $17.5 million in 2022 compared to $(5.8) million in 2021. Net income, adjusted for non-cash items, provided $52.2 million of operating cash flow in 2022 compared to $28.7 million of operating cash flow in 2021. The net change in working capital used was $34.6 million of operating cash flow in 2022 compared to $34.5 million of operating cash flow in 2021. Net Cash Used in Investing Activities Net cash used in investing activities was $23.1 million in 2022 compared to $100.2 million in 2021. Acquisitions of businesses, net of cash acquired, were $0 in 2022 compared to $87.2 million in 2021. Capital expenditures were $22.8 million in 2022 compared to $13.3 million in 2021, which includes $10.1 million in 2022 of investment in our new reinforced concrete pipe mill, and the remainder primarily for standard capital replacement. We currently expect capital expenditures in 2023 to be approximately $24 million to $28 million, which includes approximately $5 million of investment in our new reinforced concrete pipe mill, and associated ancillary equipment, and the remainder primarily for standard capital replacement. Net Cash Provided by Financing Activities Net cash provided by financing activities was $6.2 million in 2022 compared $71.0 million in 2021. Net borrowings (repayments) on the line of credit were $(3.1) million in 2022 compared $86.8 million in 2021. Net borrowings (repayments) on other debt were $10.8 million in 2022 compared to $(13.8) million in 2021. We anticipate that our existing cash and cash equivalents, cash flows expected to be generated by operations, and additional borrowing capacity under the Amended Credit Agreement and other loans will be adequate to fund our working capital, debt service, and capital expenditure requirements for at least the next twelve months. To the extent necessary, we may also satisfy capital requirements through additional bank borrowings, senior notes, term notes, subordinated debt, and finance and operating leases, if such resources are available on satisfactory terms. We have from time to time evaluated and continue to evaluate opportunities for acquisitions and expansion. Any such transactions, if consummated, may necessitate additional bank borrowings or other sources of funding. As previously discussed, we acquired ParkUSA in October 2021 which was funded primarily by borrowings on the line of credit. On November 3, 2020, our shelf registration statement on Form S‑3 (Registration No. 333‑249637) covering the potential future sale of up to $150 million of our equity and/or debt securities or combinations thereof, was declared effective by the SEC. This shelf registration statement provides another potential source of capital, in addition to other alternatives already in place. We cannot be certain that funding will be available on favorable terms or available at all. To the extent that we raise additional funds by issuing equity securities, our shareholders may experience significant dilution. As of the date of this 2022 Form 10‑K, we have not yet sold any securities under this registration statement, nor do we have an obligation to do so. Please refer to the factors discussed in Part I — Item 1A. “Risk Factors” of this 2022 Form 10‑K. 27 Table of Contents On September 2, 2022, we entered into the At-the-Market Offering with Jefferies, pursuant to which we may issue and sell shares of our common stock, par value $0.01 per share, having aggregate offering sales proceeds of up to $50 million from time to time through Jefferies as our sales agent. We may sell the Shares in amounts and at times to be determined by us from time to time subject to the terms and conditions of the At-the-Market Offering, but we have no obligation to sell any of the Shares under the At-the-Market Offering. The Shares to be sold under the At-the-Market Offering, if any, will be offered and sold pursuant to our shelf registration statement on Form S‑3 discussed above, and the prospectus supplement dated September 2, 2022 filed by us. We will pay Jefferies a cash commission of up to 3.0% of gross proceeds from the sale of the Shares pursuant to the At-the-Market Offering. We have also agreed to provide Jefferies with customary indemnification and contribution rights. No proceeds were raised under the At-the-Market Offering during the year ended December 31, 2022. Current Debt In August 2022, we entered into an Interim Funding Agreement (“IFA”) with Wells Fargo Equipment Finance, Inc. (“WFEF”) allowing for aggregate interim funding advances up to $13.5 million of equipment purchased for a new reinforced concrete pipe mill, to be converted into a term loan upon final delivery and acceptance of the financed equipment. The IFA bears interest at the Term Secured Overnight Finance Rate (“SOFR”) plus 1.75%, requires monthly payments of accrued interest, and grants a security interest in the equipment to WFEF. As of December 31, 2022, the outstanding balance of the IFA was $10.8 million, which is classified as a current liability since there is not a firm commitment for long-term debt financing. Credit Agreement The Amended Credit Agreement provides for a revolving loan, swingline loan, and letters of credit in the aggregate amount of up to $125 million (“Revolver Commitment”). The Amended Credit Agreement will expire, and all obligations outstanding will mature, on June 30, 2024. We may prepay outstanding amounts in our discretion without penalty at any time, subject to applicable notice requirements. As of December 31, 2022 under the Amended Credit Agreement, we had $83.7 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $40 million. Based on our business plan and forecasts of operations, we expect to have sufficient credit available to support our operations for at least the next twelve months. Revolving loans under the Amended Credit Agreement bear interest at rates related to, at our option and subject to the provisions of the Amended Credit Agreement, either: (i) Base Rate (as defined in the Amended Credit Agreement) plus the Applicable Margin; (ii) Adjusted Term SOFR (as defined in the Amended Credit Agreement) plus the Applicable Margin; or (iii) Adjusted Daily Simple SOFR (as defined in the Amended Credit Agreement) plus the Applicable Margin. The “Applicable Margin” is 1.75% to 2.35%, depending on our Consolidated Senior Leverage Ratio (as defined in the Amended Credit Agreement) and the interest rate option chosen. Interest on outstanding revolving loans is payable monthly. Swingline loans under the Amended Credit Agreement bear interest at the Base Rate plus the Applicable Margin. The Amended Credit Agreement requires the payment of a commitment fee of between 0.30% and 0.40%, based on the amount by which the Revolver Commitment exceeds the average daily balance of outstanding borrowings (as defined in the Amended Credit Agreement). Such fee is payable monthly in arrears. We are also obligated to pay additional fees customary for credit facilities of this size and type. The letters of credit outstanding as of December 31, 2022 relate to workers’ compensation insurance. Based on the nature of these arrangements and our historical experience, we do not expect to make any material payments under these arrangements. The Amended Credit Agreement contains customary representations and warranties, as well as customary affirmative and negative covenants, events of default, and indemnification provisions in favor of the Lenders. The negative covenants include restrictions regarding the incurrence of liens and indebtedness, annual capital expenditures, certain investments, acquisitions, and dispositions, and other matters, all subject to certain exceptions. The Amended Credit Agreement requires us to regularly provide financial information to Wells Fargo and to maintain a consolidated senior leverage ratio no greater than 2.50 to 1.00 (subject to certain exceptions) and a minimum consolidated earnings before interest, taxes, depreciation, and amortization (as defined in the Amended Credit Agreement) of at least $31.5 million for the four consecutive fiscal quarters most recently ended. Pursuant to the Amended Credit Agreement, we have also agreed that we will not sell, assign, or otherwise dispose or encumber, any of our owned real property. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. We were in compliance with our financial covenants as of December 31, 2022. Based on our business plan and forecasts of operations, we believe we will remain in compliance with our financial covenants for the next twelve months. Our obligations under the Amended Credit Agreement are secured by a senior security interest in substantially all of our and our subsidiaries’ assets. 28 Table of Contents Recent Accounting Pronouncements For a description of recent accounting pronouncements affecting our company, including the dates of adoption and estimated effects on financial position, results of operations, and cash flows, see Note 2 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. Critical Accounting Estimates Management Estimates The preparation of our Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. On an ongoing basis, we evaluate all of our estimates including those related to revenue recognition, business combinations, goodwill, inventories, property and equipment, including depreciation and valuation, intangible assets, including amortization, share-based compensation, income taxes, allowance for doubtful accounts, and litigation and other contingencies. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies and related judgments and estimates affect the preparation of our Consolidated Financial Statements. Revenue Recognition SPP revenue for water infrastructure steel pipe products is recognized over time as the manufacturing process progresses because of our right to payment for work performed to date plus a reasonable profit on cancellations for unique products that have no alternative use to us. Revenue is measured by the costs incurred to date relative to the estimated total direct costs to fulfill each contract (cost-to-cost method). Contract costs include all material, labor, and other direct costs incurred in satisfying performance obligations. The cost of steel material is recognized as a contract cost when the steel is introduced into the manufacturing process. Estimated total costs of each contract are reviewed on a monthly basis by project management and operations personnel for all active projects. All cost revisions that result in a material change in gross profit are reviewed by senior management personnel. Significant judgment is required in estimating total costs and measuring the progress of project completion, as well as whether a loss is expected to be incurred on the contract. We use certain assumptions and develop estimates based on a number of factors, including the degree of required product customization, our historical experience, the project plans, and an assessment of the risks and uncertainties inherent in the contract related to implementation delays or performance issues that may or may not be within our control. Changes in job performance, job conditions, and estimated profitability, including those arising from contract change orders, contract penalty provisions, foreign currency exchange rate movements, changes in raw materials costs, and final contract settlements may result in revisions to estimates of revenue, costs, and income, and are recognized in the period in which the revisions are determined. Provisions for losses on uncompleted contracts are estimated by comparing total estimated contract revenue to the total estimated contract costs and a loss is recognized during the period in which it becomes probable and can be reasonably estimated. Precast revenue for water infrastructure concrete pipe and precast concrete products is recognized at the time control is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for the products. All variable consideration that may affect the total transaction price, including contractual discounts, returns, and credits, is included in net sales. Estimates for variable consideration are based on historical experience, anticipated performance, and management’s judgment. Our contracts do not contain significant financing. We generally do not recognize revenue on a contract until the contract has approval and commitment from both parties, the contract rights and payment terms can be identified, the contract has commercial substance, and its collectability is probable. Business Combinations Business combinations are accounted for under the acquisition method which requires identifiable assets acquired and liabilities assumed in the business acquired be recognized and measured at fair value on the acquisition date, which is the date that the acquirer obtains control of the acquired business. The amount by which the fair value of consideration transferred as the purchase price exceeds the net fair value of assets acquired and liabilities assumed is recorded as goodwill. The amount by which the net fair value of assets acquired and liabilities assumed exceeds the fair value of consideration transferred as the purchase price is recorded as a bargain purchase gain. Acquisition-related costs are expensed as incurred. 29 Table of Contents Accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to allocate purchase price consideration properly. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Our significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted- average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill or bargain purchase gain. Goodwill Goodwill is reviewed for impairment annually, or whenever events occur or circumstances change that indicate goodwill may be impaired. Goodwill is tested for impairment at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment (also known as a component). During the fourth quarter of 2022, we changed the date of our annual impairment test of goodwill from December 31 to November 30. The change in the impairment test date will lessen resource constraints that exist in connection with our year-end close and financial reporting process and provide for additional time to complete the required impairment testing. This change does not represent a material change to our method of applying an accounting principle, and therefore does not delay, accelerate, or avoid an impairment charge. In testing goodwill for impairment, we have the option to perform a qualitative assessment to determine whether the existence of events or circumstances indicate that it is more-likely-than-not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. When performing a qualitative assessment, we evaluate factors such as industry and market conditions, cost factors, overall financial performance, and other relevant entity specific events and changes. In the evaluation, we look at the long-term prospects for the reporting unit and recognize that current performance may not be the best indicator of future prospects or value, which requires management judgment. If the qualitative assessment indicates that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, or if we choose not to perform the qualitative assessment, then a quantitative assessment is performed to determine the reporting unit’s fair value. The fair value calculation uses a combination of income and market approaches. The income approach is based upon projected future after-tax cash flows discounted to present value using factors that consider the timing and risk associated with the future after-tax cash flows. The market approach is based upon historical and/or forward- looking measures using multiples of revenue or earnings before interest, tax, depreciation, and amortization. We utilize a weighted average of the income and market approaches. If the reporting unit’s carrying value exceeds its fair value, then an impairment loss is recognized for the amount of the excess of the carrying amount over the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Inventories Inventories are stated at the lower of cost and net realizable value. Determining net realizable value of inventories involves judgments and assumptions, including projecting selling prices and cost of sales. To estimate net realizable value, we review recent sales and gross profit history, existing customer orders, current contract prices, industry supply and demand, forecasted steel prices, replacement costs, seasonal factors, general economic trends, and other information, as applicable. If future market conditions are less favorable than those projected by us, inventory write-downs may be required. The cost of raw material inventories of steel is either on a specific identification basis or on an average cost basis. The cost of substantially all other raw material inventories, as well as work-in-process and supplies, is on an average cost basis. The cost of finished goods uses the first-in, first-out method of accounting. Property and Equipment and Intangible Assets Property and equipment are recorded at cost, and are depreciated using either the units of production method or the straight-line method depending on the classification of the asset. Depreciation expense calculated under the units of production method may be less than, equal to, or greater than depreciation expense calculated under the straight-line method. We evaluate historical and projected units of production at each facility to reassess the units of production expected on an annual basis. Intangible assets consist primarily of customer relationships, trade names and trademarks, patents, and backlog recorded as the result of acquisition activity. Intangible assets are amortized using the straight-line method over estimated useful lives. 30 Table of Contents We assess impairment of property and equipment and intangible assets whenever changes in circumstances indicate that the carrying values of the asset or asset group(s) may not be recoverable. The recoverable value of a long-lived asset group is determined by estimating future undiscounted cash flows using assumptions about our expected future operating performance. Estimates of future cash flows used in the recoverability test incorporate our own assumptions about the use of the asset group and shall consider all available evidence. Our estimates of undiscounted cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions, or changes to our business operations. If we determine the carrying value of the property and equipment and intangible assets will not be recoverable, we calculate and record an impairment loss. Share-based Compensation We recognize the compensation cost of employee and director services received in exchange for awards of equity instruments based on the grant date estimated fair value of the awards. We estimate the fair value of restricted stock units and performance share awards using the value of our stock on the date of grant. Share-based compensation cost is recognized over the period during which the employee or director is required to provide service in exchange for the award and, as forfeitures occur, the associated compensation cost recognized to date is reversed. For awards with performance-based payout conditions, we recognize compensation cost based on the probability of achieving the performance conditions, with changes in expectations recognized as an adjustment to earnings in the period of change. Any recognized compensation cost is reversed if the conditions are ultimately not met. Income Taxes Income taxes are recorded using an asset and liability approach that requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in our Consolidated Financial Statements or income tax returns. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. Our provision for income taxes primarily reflects a combination of income earned and taxed in the various United States federal, state, local, and to a lesser extent, foreign jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized income tax benefits or valuation allowances, and our change in the mix of earnings from these taxing jurisdictions all affect the overall effective income tax rate. We record income tax reserves for federal, state, local, and international exposures relating to periods subject to audit. The development of reserves for these exposures requires judgments about tax issues, potential outcomes and timing, and is a subjective estimate. We assess our income tax positions and record income tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting dates. For those income tax positions where it is more-likely-than-not that an income tax benefit will be sustained, we have recorded the largest amount of income tax benefit with a greater than 50% likelihood of being realized upon settlement with a tax authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that an income tax benefit will be sustained, no income tax benefit has been recognized in the Consolidated Financial Statements. Allowance for Doubtful Accounts We maintain allowances for estimated losses resulting from the inability of our customers to make required payments or from contract disputes. The amounts of such allowances are based on historical experience and management’s judgment. The extension and revision of credit is determined by obtaining credit rating reports or financial information on the customer. An allowance is recorded based on a variety of factors, including our historical collection experience and our historical product quality claims. At least monthly, we review past due balances to identify the reasons for non-payment. We will write down or write off a receivable account once the account is deemed uncollectible for reasons such as customer quality claims, a contract dispute, deterioration in the customer’s financial position, a bankruptcy filing, or other events. If the customer’s financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes were to escalate, additional allowances may need to be recorded which would result in additional expenses being recorded for the period in which such determination was made. 31 Table of Contents Item 7A. Quantitative and Qualitative Disclosures About Market Risk The primary market risks affecting our business relate to our exposure to commodity risk, interest rate risk, and foreign currency exchange rate risk. Commodity Risk Certain materials we use in our business are classified as commodities traded in the worldwide markets, of which the most significant commodity is steel, used in the manufacturing of pipe. We do not hedge our commodity risk and do not enter into any transactions in commodities for trading purposes. The impact of volatility in steel prices varies significantly. This volatility can significantly affect our gross profit. Although we seek to recover increases in steel prices through price increases in our products, we have not always been successful. Steel typically makes up approximately 35% of SPP’s project costs. As this raw material represents a substantial portion of our cost of sales, we attempt to minimize our risk exposure to steel price volatility by submitting bids based on general assumptions of the expected price of steel when we will receive a purchase order or contract, which is typically awarded within 30 to 90 days of the bid date, as well as ordering steel as soon as possible after a project is contracted. Interest Rate Risk Our debt bears interest at both fixed and variable rates. As of December 31, 2022 and 2021, we had $94.5 million and $86.8 million, respectively, of variable-rate debt outstanding. We have managed a portion of our variable-rate debt with an interest rate swap agreement to effectively convert a portion of our variable-rate debt to fixed-rate debt. The principal objective of this contract is to reduce the variability of the cash flows in interest payments associated with a portion of our variable-rate debt, thus reducing the impact of interest rate changes on future interest payment cash flows. We have elected to apply the hedge accounting rules in accordance with authoritative guidance for this contract. As of December 31, 2022, the total notional amount of the interest rate swap was $26.7 million, which will amortize ratably on a monthly basis to zero by the April 2024 maturity date. We receive floating interest payments monthly based on the SOFR and pay a fixed rate of 1.941% to the counterparty. Assuming average interest rates and borrowings on variable-rate debt, a hypothetical 1.0%, or 100 basis points, change in interest rates would not have a material impact on our interest expense in 2022 or 2021. Foreign Currency Exchange Rate Risk We conduct business in various foreign countries and, from time to time, settle our transactions in foreign currencies. We have experienced and will continue to experience fluctuations in our net income as a result of gains (losses) on the settlement and the remeasurement of monetary assets and liabilities denominated in currencies that are not our functional currency. As of December 31, 2022, our foreign currency exposures were between the U.S. Dollar and the Canadian Dollar, Mexican Peso, and European Euro. We have established a program that utilizes foreign currency forward contracts to offset the risk associated with the effects of certain foreign currency exposures. Foreign currency forward contracts are consistent with our strategy for financial risk management and are not used for trading or for speculative purposes. As of December 31, 2022, the total notional amount of the foreign currency forward contracts was $17.1 million (CAD$23.2 million) and $1.1 million (EUR$1.1 million), which included $0.3 million (CAD$0.4 million) of foreign currency forward contracts not designated as cash flow hedges. As of December 31, 2022, our foreign currency forward contracts mature at various dates through October 2023. As of December 31, 2021, the total notional amount of these foreign currency forward contracts was $19.0 million (CAD$24.1 million), of which we applied hedge accounting to all. A hypothetical 10% change in the Canadian Dollar, Mexican Peso, or European Euro foreign currency exchange rates would not have a material impact on our reported net income in 2022 or 2021. Item 8.

Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”)) are designed to provide reasonable assurance that information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (“SEC”) and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosures. Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. Based on their evaluation, as of December 31, 2022, our CEO and CFO have concluded that our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act) were not effective due to the material weakness in our internal control over financial reporting as described below. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act. 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 accounting principles generally accepted in the United States of America (“U.S. GAAP”). Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that our transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an assessment of our internal control over financial reporting as of December 31, 2022. In making this assessment, we used the criteria set forth in “Internal Control-Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management concluded that our internal control over financial reporting was not effective as of December 31, 2022 due to the material weakness in our internal control over financial reporting, as follows: Subsequent to our acquisition of Park Environmental Equipment, LLC (“ParkUSA”), a privately held company, we instituted new internal controls, processes and procedures, and we converted ParkUSA to our enterprise resource planning (“ERP”) system. We have identified control deficiencies related to that system implementation project. Specifically, we did not exercise sufficient oversight, design effective controls to ensure completeness of the data conversion, or conduct sufficient testing to ensure the system would operate effectively. Additionally, we were unable to implement and evidence compensating business controls specific to ParkUSA’s sales transactions and cost of sales transactions. As a result, these business process control deficiencies, when combined with the ERP implementation control deficiencies, create a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis. Moss Adams LLP, an independent registered public accounting firm, has issued an adverse opinion on the effectiveness of our internal control over financial reporting as of December 31, 2022, which is included in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K. 33 Table of Contents As a result of the identification of the material weakness, and prior to filing this 2022 Form 10‑K, we performed further analysis and completed additional procedures intended to ensure our consolidated financial statements for the year ended December 31, 2022 were prepared in accordance with U.S. GAAP. Based on these procedures and analysis, and notwithstanding the material weakness in our internal control over financial reporting, our management has concluded that our consolidated financial statements and related notes thereto included in this 2022 Form 10‑K have been prepared in accordance with U.S. GAAP. Our CEO and CFO have certified that, based on each such officer’s knowledge, the financial statements, as well as the other financial information included in this 2022 Form 10‑K, fairly present in all material respects our financial condition, results of operations and cash flows as of, and for, the periods presented in this 2022 Form 10‑K. In addition, Moss Adams LLP has issued an unqualified opinion on our financial statements, which is included in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2022 Form 10‑K, and we have developed a remediation plan for the material weakness, which is described below. Planned Remediation We have taken, and continue to take, steps to remediate the control deficiencies contributing to the material weakness described in this Item 9A. These remediation actions include: hiring consultants to assist with an evaluation of the ERP system, process, and workflow design; educating control owners concerning the principles and requirements of each control, with a focus on those related to sales and cost of sales transactions; and implementing new monitoring controls including additional analyses to help mitigate the risk that controls do not operate effectively. We will report regularly to our Audit Committee on the progress and results of our remediation plan, and we may take additional measures to address these control deficiencies, or we may modify certain of the remediation measures described above. Management is committed to taking the necessary steps to ensure that our internal control over financial reporting is designed and operating effectively, and we intend to remediate this material weakness as soon as possible and believe the measures described above will do so. This material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded through testing that the controls are operating effectively. We anticipate that the remediation will be completed during 2023. Changes in Internal Control over Financial Reporting Except for the material weakness identified by management and described above, there were no significant changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Form 10‑K Summary None. 40 Table of Contents Report of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of Northwest Pipe Company Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Northwest Pipe Company and Subsidiaries (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 and schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2022 and 2021, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, because of the effect of the material weakness identified below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, 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 Report on Internal Control over Financial Reporting included in Item 9A. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 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 consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment in Item 9A: The Company converted the recently acquired Park Environmental Equipment, LLC (“ParkUSA”) subsidiary to its enterprise resource planning (ERP) system, and the Company did not design and maintain effective controls to ensure completeness of the data converted or conduct sufficient testing to ensure the system would operate effectively for sales and cost of sales transactions. In addition, the Company was unable to implement and evidence compensating business process controls specific to ParkUSA’s sales and cost of sales transactions. We considered the material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the Company’s consolidated financial statements as of and for the year ended December 31, 2022, and our opinion on such consolidated financial statements was not affected. F-1 Table of Contents 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. 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. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated 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 consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 – Estimated Costs to Complete a Contract As presented in the consolidated statement of operations and described in Notes 2 and 16 to the consolidated financial statements, the Company’s consolidated revenues and costs of revenue were $457.7 million and $371.8 million, respectively, for the year ended December 31, 2022. Revenue of $307.6 million was derived from contracts where revenue is recognized over time as work is completed because of the continuous transfer of control to the customer. Under this method, the costs incurred to date as a percentage of total estimated costs at completion are used to calculate revenue. Total estimated costs, and thus contract revenue and margin, are impacted by many factors, which can cause significant changes in estimates during the life cycle of a project. Based on the high degree of subjectivity involved in the determination of estimated costs to complete a contract, which in turn led to a high degree of auditor effort and subjectivity in performing procedures and evaluating audit evidence, we have identified these estimates as a critical audit matter. Changes in these estimates could have significant impact on both the timing and amount of contract revenue to be recognized. The primary procedures we performed to address this critical audit matter included: • Testing the design and operating effectiveness of internal controls related to the Company’s accumulation of estimated costs to complete a contract. This included testing controls over the Company’s review of monthly changes in estimated costs to complete a contract. • Testing a selection of contracts based on earned revenue for the year ended December 31, 2022 and assessed the reasonableness of the estimated costs. • Testing the reasonableness of management’s cost estimates by performing a lookback analysis comparing margins and estimated costs to complete on contracts in process as of December 31, 2021, that were completed or in process during the year ended December 31, 2022. /s/ Moss Adams LLP Portland, Oregon March 16, 2023 We have served as the Company’s auditor since 2016.

F-8 Table of Contents 1. ORGANIZATION: NORTHWEST PIPE COMPANY AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Northwest Pipe Company (collectively with its subsidiaries, the “Company”) is a leading manufacturer of water-related infrastructure products, and operates in two segments, Engineered Steel Pressure Pipe (“SPP”) and Precast Infrastructure and Engineered Systems (“Precast”). This segment presentation is consistent with how the Company’s chief operating decision maker, its Chief Executive Officer, evaluates performance of the Company and makes decisions regarding the allocation of resources. See Note 19, “Segment Information” for detailed descriptions of these segments. In addition to being the largest manufacturer of engineered steel water pipeline systems in North America, the Company manufactures stormwater and wastewater technology products; high-quality precast and reinforced concrete products; pump lift stations; steel casing pipe, bar-wrapped concrete cylinder pipe, and one of the largest offerings of pipeline system joints, fittings, and specialized components. Strategically positioned to meet growing water and wastewater infrastructure needs, the Company provides solution-based products for a wide range of markets under the ParkUSA, Geneva Pipe and Precast, Permalok®, and Northwest Pipe Company lines. The Company is headquartered in Vancouver, Washington, and has 13 manufacturing facilities across North America. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Consolidation and Presentation The Consolidated Financial Statements are expressed in United States Dollars and include the accounts of the Company and its subsidiaries over which the Company exercises control as of the financial statement date. Intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. On an ongoing basis, the Company evaluates all of its estimates, including those related to business combinations, allowance for doubtful accounts, inventories, property and equipment (including depreciation and valuation), goodwill, intangible assets (including amortization), revenue recognition, share-based compensation, income taxes, and litigation and other contingencies. Actual results may differ from these estimates under different assumptions or conditions. Business Combinations Business combinations are accounted for under the acquisition method which requires identifiable assets acquired and liabilities assumed in the business acquired be recognized and measured at fair value on the acquisition date, which is the date that the acquirer obtains control of the acquired business. The amount by which the fair value of consideration transferred as the purchase price exceeds the net fair value of assets acquired and liabilities assumed is recorded as goodwill. The amount by which the net fair value of assets acquired and liabilities assumed exceeds the fair value of consideration transferred as the purchase price is recorded as a bargain purchase gain. Acquisition-related transaction costs are expensed as incurred. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill or bargain purchase gain. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s Consolidated Statements of Operations. F- 9 Table of Contents Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term, highly-liquid investments with maturities of three months or less when purchased. At times, the Company will have outstanding checks in excess of related bank balances (“book overdraft”). If this occurs, the amount of the book overdraft will be reclassified to accounts payable, and changes in the book overdraft will be reflected as a component of operating activities in the Consolidated Statements of Cash Flows. The Company had a book overdraft of $0.6 million and $4.1 million as of December 31, 2022 and 2021, respectively. Receivables and Allowance for Doubtful Accounts Trade receivables are reported on the Consolidated Balance Sheets net of doubtful accounts. The Company maintains allowances for estimated losses resulting from the inability of its customers to make required payments or from contract disputes. The amounts of such allowances are based on historical experience and management’s judgment. The Company will write down or write off a receivable account once the account is deemed uncollectible. If the customers’ financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes were to escalate, additional allowances may need to be recorded which would result in additional expenses being recorded for the period in which such determination was made. Contract Assets and Liabilities Contract assets primarily represent revenue earned over time but not yet billable based on the terms of the contracts. These amounts will be billed based on the terms of the contracts, which can include certain milestones, partial shipments, or completion of the contracts. Payment terms of amounts billed vary based on the customer, but are typically due within 30 days of invoicing. Contract liabilities represent advance billings on contracts, typically for steel. Inventories Inventories are stated at the lower of cost and net realizable value. The cost of raw material inventories of steel is either on a specific identification basis or on an average cost basis. The cost of substantially all other raw material inventories, as well as work-in-process and supplies, is on an average cost basis. The cost of finished goods uses the first-in, first-out method of accounting. Property and Equipment Property and equipment are recorded at cost. Maintenance and repairs are expensed as incurred, and costs of new equipment and buildings, as well as costs of expansions or refurbishment of existing equipment and buildings, including interest where applicable, are capitalized. Depreciation and amortization are determined by the units of production method for most equipment and by the straight-line method for the remaining assets based on the estimated useful lives of the related assets. Estimated useful lives by major classes of property and equipment are as follows: Land improvements (15 – 30 years); Buildings (20 – 40 years); Leasehold improvements (5 – 30 years); and Machinery and equipment (3 – 30 years). Depreciation expense calculated under the units of production method may be less than, equal to, or greater than depreciation expense calculated under the straight-line method due to variances in production levels. Upon disposal, costs and related accumulated depreciation of the assets are removed from the accounts and resulting gains or losses are reflected in operating expenses. The Company leases certain equipment under long-term finance leases, which are being amortized on a straight-line basis over the shorter of its useful life or the lease term. The Company assesses impairment of property and equipment whenever changes in circumstances indicate that the carrying values of the asset or asset group(s) may not be recoverable. The asset group is the lowest level at which identifiable cash flows are largely independent of the cash flows of other groups of assets or liabilities. The recoverable value of a long-lived asset group is determined by estimating future undiscounted cash flows using assumptions about the expected future operating performance of the Company. Leases The Company has entered into various equipment and property leases. Certain lease agreements include renewals and/or purchase options set to expire at various dates, and certain lease agreements include rental payments adjusted periodically for inflation. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. F- 10 Table of Contents The Company determines if an arrangement is a lease at inception. Leases with an initial term of twelve months or less are not recorded on the balance sheet; costs for these leases are recognized on a straight-line basis over the lease term. Right-of-use assets and lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Company’s leases do not provide an implicit rate of return, the Company uses its revolving loan borrowing rate in determining the present value of lease payments. Some of the Company’s lease agreements contain non-lease components, which are accounted for separately. Goodwill Goodwill represents the excess of the purchase price over the fair values of the assets acquired and liabilities assumed in conjunction with an acquisition. Goodwill is reviewed for impairment annually, or whenever events occur or circumstances change that indicate goodwill may be impaired. During the fourth quarter of 2022, the Company changed the date of its annual impairment test of goodwill from December 31 to November 30. The change in the impairment test date will lessen resource constraints that exist in connection with the Company’s year-end close and financial reporting process and provide for additional time to complete the required impairment testing. This change does not represent a material change to the Company’s method of applying an accounting principle, and therefore does not delay, accelerate, or avoid an impairment charge. In testing goodwill for impairment, the Company has the option to perform a qualitative assessment to determine whether the existence of events or circumstances indicate that it is more-likely-than-not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. When performing a qualitative assessment, the Company evaluates factors such as industry and market conditions, cost factors, overall financial performance, and other relevant entity specific events and changes. If the qualitative assessment indicates that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, or if the Company chooses not to perform the qualitative assessment, then a quantitative assessment is performed to determine the reporting unit’s fair value. If the reporting unit’s carrying value exceeds its fair value, then an impairment loss is recognized for the amount of the excess of the carrying amount over the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Intangible Assets Intangible assets consist primarily of customer relationships, trade names and trademarks, patents, and backlog recorded as the result of acquisition activity. Intangible assets are amortized using the straight-line method over estimated useful lives ranging from three to 21 years. Workers Compensation The Company is self-insured and maintains high deductible policies for losses and liabilities associated with workers compensation claims. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. As of December 31, 2022 and 2021, workers compensation reserves recorded were $1.6 million and $1.7 million, respectively, of which $0.5 million and $0.4 million, respectively, were included in Accrued liabilities and $1.1 million and $1.3 million, respectively, were included in Other long-term liabilities. Accrued Liabilities Accrued liabilities as of December 31, 2022 and 2021 includes $8.0 million and $3.7 million, respectively, of accrued bonus. Derivative Instruments In the normal course of business, the Company is exposed to interest rate and foreign currency exchange rate fluctuations. Consistent with the Company’s strategy for financial risk management, the Company has established a program that utilizes foreign currency forward contracts and interest rate swaps to offset the risks associated with the effects of these exposures. The Company utilizes cash flow hedge accounting treatment for qualifying foreign currency forward contracts and interest rate swaps. Instruments that do not qualify for cash flow hedge accounting treatment are remeasured at fair value on each balance sheet date and resulting gains and losses are recognized in earnings. Pension Benefits The Company has two defined benefit pension plans that have been frozen since 2001. The Company funds these plans to cover current plan costs plus amortization of the unfunded plan liabilities. To record these obligations, management uses estimates relating to investment returns, mortality, and discount rates. F- 11 Table of Contents Foreign Currency Transactions The functional currency of the Company, including its Mexican operations, is the United States dollar. Monetary assets and liabilities are remeasured at current exchange rates and non-monetary assets and liabilities are remeasured at historical exchange rates. Revenue and expenses related to monetary assets and liabilities are remeasured at average exchange rates and at historical exchange rates for the revenue and expenses related to non-monetary assets and liabilities. Transaction gains (losses) from foreign currency forward contracts designated as cash flow hedges are included in Accumulated other comprehensive loss as a separate component of Stockholders’ equity. For the years ended December 31, 2022, 2021, and 2020, net foreign currency transaction gains (losses) of $0.5 million, $(0.5) million, and $(1.1) million, respectively, were recognized in earnings. Revenue Recognition The Company manufactures water infrastructure steel pipe products, which are generally made to custom specifications for installation contractors serving projects funded by public water agencies, as well as precast and reinforced concrete products. Generally, each of the Company’s contracts with its customers contains a single performance obligation, as the promise to transfer products is not separately identifiable from other promises in the contract and, therefore, is not distinct. The Company generally does not recognize revenue on a contract until the contract has approval and commitment from both parties, the contract rights and payment terms can be identified, the contract has commercial substance, and its collectability is probable. SPP revenue for water infrastructure steel pipe products is recognized over time as the manufacturing process progresses because of the Company’s right to payment for work performed to date plus a reasonable profit on cancellations for unique products that have no alternative use to the Company. Revenue is measured by the costs incurred to date relative to the estimated total direct costs to fulfill each contract (cost-to-cost method). Contract costs include all material, labor, and other direct costs incurred in satisfying the performance obligations. The cost of steel material is recognized as a contract cost when the steel is introduced into the manufacturing process. Changes in job performance, job conditions, and estimated profitability, including those arising from contract change orders, contract penalty provisions, foreign currency exchange rate movements, changes in raw materials costs, and final contract settlements may result in revisions to estimates of revenue, costs, and income, and are recognized in the period in which the revisions are determined. Provisions for losses on uncompleted contracts, included in Accrued liabilities, are estimated by comparing total estimated contract revenue to the total estimated contract costs and a loss is recognized during the period in which it becomes probable and can be reasonably estimated. Precast revenue for water infrastructure concrete pipe and precast concrete products is recognized at the time control is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for the products. All variable consideration that may affect the total transaction price, including contractual discounts, returns, and credits, is included in net sales. Estimates for variable consideration are based on historical experience, anticipated performance, and management’s judgment. The Company’s contracts do not contain significant financing. Share-based Compensation The Company recognizes the compensation cost of employee and director services received in exchange for awards of equity instruments based on the grant date estimated fair value of the awards. The Company estimates the fair value of restricted stock units (“RSUs”) and performance share awards (“PSAs”) using the value of the Company’s stock on the date of grant. Share-based compensation cost is recognized over the period during which the employee or director is required to provide service in exchange for the award and, as forfeitures occur, the associated compensation cost recognized to date is reversed. For awards with performance-based payout conditions, the Company recognizes compensation cost based on the probability of achieving the performance conditions, with changes in expectations recognized as an adjustment to earnings in the period of change. Any recognized compensation cost is reversed if the conditions are ultimately not met. F- 12 Table of Contents Income Taxes Income taxes are recorded using an asset and liability approach that requires the recognition of deferred income tax assets and liabilities for the expected future income tax consequences of events that have been recognized in the Consolidated Financial Statements or income tax returns. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. The determination of the provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. The provision for income taxes primarily reflects a combination of income earned and taxed in the various United States federal, state, local, and to a lesser extent, foreign jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized income tax benefits or valuation allowances, and the change in the mix of earnings from these taxing jurisdictions all affect the overall effective income tax rate. The Company records income tax reserves for federal, state, local, and international exposures relating to periods subject to audit. The development of reserves for these exposures requires judgments about tax issues, potential outcomes and timing, and is a subjective estimate. The Company assesses income tax positions and records income tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting dates. For those income tax positions where it is more-likely-than-not that an income tax benefit will be sustained, the Company has recorded the largest amount of income tax benefit with a greater than 50% likelihood of being realized upon settlement with a tax authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that an income tax benefit will be sustained, no income tax benefit has been recognized in the Consolidated Financial Statements. Accumulated Other Comprehensive Loss Accumulated other comprehensive loss includes unrealized gains and losses on derivative instruments related to the effective portion of cash flow hedges and changes in the funded status of the defined benefit pension plans, both net of the related income tax effect. Net Income per Share Basic net income per share is computed by dividing the net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by giving effect to all potential shares of common stock, including stock options, RSUs, and PSAs, to the extent dilutive. Performance-based PSAs are considered dilutive when the related performance conditions have been met assuming the end of the reporting period represents the end of the performance period. In periods with a net loss, all potential shares of common stock are excluded from the computation of diluted net loss per share as the impact would be antidilutive. Net income per basic and diluted weighted-average common share outstanding was calculated as follows (in thousands, except per share amounts): 2022 Year Ended December 31, 2021 2020 Net income $ 31,149 $ 11,523 $ Basic weighted-average common shares outstanding Effect of potentially dilutive common shares (1) Diluted weighted-average common shares outstanding Net income per common share Basic Diluted 9,914 98 10,012 3.14 $ 3.11 $ 9,854 74 9,928 1.17 $ 1.16 $ $ $ 19,050 9,788 85 9,873 1.95 1.93 (1) There were no antidilutive shares for the years ended December 31, 2022, 2021, or 2020. F- 13 Table of Contents Concentrations of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of trade receivables, foreign currency forward contracts, interest rate swaps, and deferred compensation plan assets. Trade receivables generally represent a large number of customers, including municipalities, manufacturers, distributors, and contractors, dispersed across a wide geographic base. As of December 31, 2022, one customer had a balance in excess of 10% of total accounts receivable. As of December 31, 2021, no customer had a balance in excess of 10% of total accounts receivable. Foreign currency forward contracts and interest rate swaps are with a high quality financial institution. The Company’s deferred compensation plan assets, included in Other assets, are invested in a diversified portfolio of stock and bond mutual funds. Recent Accounting and Reporting Developments Recent Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020‑04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. In January 2021, the FASB issued ASU No. 2021‑01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance. In December 2022, the FASB issued ASU No. 2022‑06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” which deferred the sunset date by two years. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2024. The Company will adopt these standards when LIBOR is discontinued and does not expect a material impact to its financial position, results of operations, or cash flows from adoption of this guidance. In October 2021, the FASB issued ASU No. 2021‑08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“ASU 2021‑08”) which requires an entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers,” as if it had originated the contracts. ASU 2021‑08 is effective for the Company beginning January 1, 2023, including interim periods in 2023, with early adoption permitted. The Company does not expect a material impact to its financial position, results of operations, or cash flows from adoption of this guidance. 3. BUSINESS COMBINATIONS: Park Environmental Equipment, LLC On October 5, 2021, the Company completed the acquisition of 100% of Park Environmental Equipment, LLC (“ParkUSA”) for a purchase price of $90.2 million in cash, which is included in the Precast segment for all periods following the acquisition date. ParkUSA is a precast concrete and steel fabrication-based company that develops and manufactures water, wastewater, and environmental solutions. Operations continue with ParkUSA’s previous management and workforce at its three Texas manufacturing facilities located in Houston, Dallas, and San Antonio. This strategic acquisition provides a foothold into the water infrastructure technology market. As the Company employs similar operating capabilities at its existing facilities, it intends to explore strategic opportunities to expand ParkUSA’s value-added products within the organization.

F- 16 Table of Contents Unaudited Pro Forma Disclosures The following unaudited pro forma summary presents the consolidated results of the Company as if the acquisition of ParkUSA had occurred on January 1, 2020 and the acquisition of Geneva had occurred on January 1, 2019 (in thousands): Net sales Net income Year Ended December 31, 2020 2021 $ 384,872 $ 15,780 356,035 20,540 This unaudited pro forma consolidated financial data is included only for the purpose of illustration and does not necessarily indicate what the operating results would have been if the acquisitions of ParkUSA and Geneva had occurred on January 1 of the respective year prior to the acquisition. Moreover, this information is not indicative of what the Company’s future operating results will be. The information prior to the acquisition is included based on prior accounting records maintained by ParkUSA and Geneva. The pro forma amounts have been calculated after applying the Company’s accounting policies and adjusting the results of ParkUSA and Geneva to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property and equipment and intangible assets had been applied on January 1 of the respective year prior to the acquisition. Adjustments also include an increase of interest expense as if the Company’s debt obtained in connection with the acquisitions of ParkUSA and Geneva had been outstanding since January 1 of the respective year prior to the acquisition. The pro forma results for the year ended December 31, 2020 also include nonrecurring adjustments relating to the recognition of transaction costs incurred and revaluation of inventory acquired. The pro forma results for the year ended December 31, 2021 include nonrecurring adjustments to add back the transaction costs incurred and the expense related to the revaluation of inventory acquired in those periods, since those costs are reflected in the preceding year on a pro forma basis. The provision for income taxes has also been adjusted for all periods, based upon the foregoing adjustments to historical results. 4.

CURRENT DEBT: $ $ 4,189 4,033 4,033 4,033 4,033 14,943 35,264 In August 2022, the Company entered into an Interim Funding Agreement (“IFA”) with Wells Fargo Equipment Finance, Inc. (“WFEF”) allowing for aggregate interim funding advances up to $13.5 million of equipment purchased for a new reinforced concrete pipe mill, to be converted into a term loan upon final delivery and acceptance of the financed equipment. The IFA bears interest at the Term Secured Overnight Finance Rate (“SOFR”) plus 1.75%, requires monthly payments of accrued interest, and grants a security interest in the equipment to WFEF. As of December 31, 2022, the outstanding balance of the IFA was $10.8 million, which is classified as a current liability since there is not a firm commitment for long-term debt financing. 8. CREDIT AGREEMENT: The Credit Agreement dated June 30, 2021 with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent, and the lenders from time to time party thereto, including the initial sole lender, Wells Fargo (the “Lenders”), as amended by the Incremental Amendment dated October 22, 2021 and the Second Amendment to Credit Agreement dated April 29, 2022 (together, the “Amended Credit Agreement”), provides for a revolving loan, swingline loan, and letters of credit in the aggregate amount of up to $125 million (“Revolver Commitment”). The Amended Credit Agreement will expire, and all obligations outstanding will mature, on June 30, 2024. The Company may prepay outstanding amounts in its discretion without penalty at any time, subject to applicable notice requirements. In conjunction with entering into the Credit Agreement on June 30, 2021, the Company terminated the Credit Agreement with Wells Fargo dated October 25, 2018, as amended on January 31, 2020 by the Consent and Amendment No. 1 to Credit Agreement with Wells Fargo (together, the “Former Credit Agreement”), and all outstanding debt under the Former Credit Agreement, including long-term debt, was repaid. The Amended Credit Agreement contains customary representations and warranties, as well as customary affirmative and negative covenants, events of default, and indemnification provisions in favor of the Lenders. The negative covenants include restrictions regarding the incurrence of liens and indebtedness, annual capital expenditures, certain investments, acquisitions, and dispositions, and other matters, all subject to certain exceptions. The Amended Credit Agreement requires the Company to regularly provide financial information to Wells Fargo and to maintain a consolidated senior leverage ratio no greater than 2.50 to 1.00 (subject to certain exceptions) and a minimum consolidated earnings before interest, taxes, depreciation, and amortization (as defined in the Amended Credit Agreement) of at least $31.5 million for the four consecutive fiscal quarters most recently ended. Pursuant to the Amended Credit Agreement, the Company has also agreed that it will not sell, assign, or otherwise dispose or encumber, any of its owned real property. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. The Company was in compliance with its financial covenants as of December 31, 2022. The Company’s obligations under the Amended Credit Agreement are secured by a senior security interest in substantially all of the Company’s and its subsidiaries’ assets. Interest expense from revolving loan borrowings, current debt, long-term debt, and finance leases was $3.6 million in 2022, $1.2 million, net of amounts capitalized of $0.1 million in 2021, and $0.9 million, net of amounts capitalized of $0.1 million in 2020. A nominal amount of interest was capitalized in 2022. F- 19 Table of Contents Line of Credit (Revolving and Swingline Loans) As of December 31, 2022 under the Amended Credit Agreement, the Company had $83.7 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $40 million. As of December 31, 2021 under the Amended Credit Agreement, the Company had $86.8 million of outstanding revolving loan borrowings and $1.6 million of outstanding letters of credit. Revolving loans under the Amended Credit Agreement bear interest at rates related to, at the Company’s option and subject to the provisions of the Amended Credit Agreement, either: (i) Base Rate (as defined in the Amended Credit Agreement) plus the Applicable Margin; (ii) Adjusted Term SOFR (as defined in the Amended Credit Agreement) plus the Applicable Margin; or (iii) Adjusted Daily Simple SOFR (as defined in the Amended Credit Agreement) plus the Applicable Margin. The “Applicable Margin” is 1.75% to 2.35%, depending on the Company’s Consolidated Senior Leverage Ratio (as defined in the Amended Credit Agreement) and the interest rate option chosen. Interest on outstanding revolving loans is payable monthly. Swingline loans under the Amended Credit Agreement bear interest at the Base Rate plus the Applicable Margin. As of December 31, 2022 and 2021, the weighted-average interest rate for outstanding borrowings was 6.07% and 1.85%, respectively. The Amended Credit Agreement requires the payment of a commitment fee of between 0.30% and 0.40%, based on the amount by which the Revolver Commitment exceeds the average daily balance of outstanding borrowings (as defined in the Amended Credit Agreement). Such fee is payable monthly in arrears. The Company is also obligated to pay additional fees customary for credit facilities of this size and type. 9.

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 the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants at the measurement date. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. These levels are: Level 1 (inputs are quoted prices in active markets for identical assets or liabilities); Level 2 (inputs are other than quoted prices that are observable, either directly or indirectly through corroboration with observable market data); and Level 3 (inputs are unobservable, with little or no market data that exists, such as internal financial forecasts). The Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. F- 21 Table of Contents The following table summarizes information regarding the Company’s financial assets and liabilities that are measured at fair value on a recurring basis (in thousands): Total Level 1 Level 2 Level 3 As of December 31, 2022 Financial assets: Deferred compensation plan Foreign currency forward contracts Interest rate swaps Total financial assets Financial liabilities: Foreign currency forward contracts As of December 31, 2021 Financial assets: Deferred compensation plan Foreign currency forward contracts Total financial assets Financial liabilities: Foreign currency forward contracts $ $ $ $ $ $ 3,587 $ 728 862 5,177 $ 3,090 $ - - 3,090 $ 497 $ 728 862 2,087 $ (80) $ - $ (80) $ 4,321 $ 17 4,338 $ 3,830 $ - 3,830 $ 491 $ 17 508 $ (661) $ - $ (661) $ - - - - - - - - - The deferred compensation plan assets consist of cash and several publicly traded stock and bond mutual funds, valued using quoted market prices in active markets, classified as Level 1 within the fair value hierarchy, as well as guaranteed investment contracts, valued at principal plus interest credited at contract rates, classified as Level 2 within the fair value hierarchy. Deferred compensation plan assets are included within Other assets in the Consolidated Balance Sheets. The foreign currency forward contracts and interest rate swaps are derivatives valued using various pricing models or discounted cash flow analyses that incorporate observable market parameters, such as interest rate yield curves and currency rates, and are classified as Level 2 within the fair value hierarchy. Derivative valuations incorporate credit risk adjustments that are necessary to reflect the probability of default by the counterparty or the Company. The foreign currency forward contracts and interest rate swaps are presented at their gross fair values. Foreign currency forward contract and interest rate swap assets are included within Prepaid expenses and other and foreign currency forward contract liabilities are included within Accrued liabilities in the Consolidated Balance Sheets. The net carrying amounts of cash and cash equivalents, trade and other receivables, accounts payable, accrued liabilities, current debt, and borrowings on the line of credit approximate fair value due to the short-term nature of these instruments. 11. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: For each derivative entered into in which the Company seeks to obtain cash flow hedge accounting treatment, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking the hedge transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method of measuring ineffectiveness. This process includes linking all derivatives to specific firm commitments or forecasted transactions and designating the derivatives as cash flow hedges. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The effective portion of these hedged items is reflected in Unrealized gain (loss) on cash flow hedges on the Consolidated Statements of Comprehensive Income. If it is determined that a derivative is not highly effective, or that it has ceased to be a highly effective hedge, the Company is required to discontinue hedge accounting with respect to that derivative prospectively. F- 22 Table of Contents As of December 31, 2022, the total notional amount of the foreign currency forward contracts was $17.1 million (CAD$23.2 million) and $1.1 million (EUR$1.1 million), which included $0.3 million (CAD$0.4 million) of foreign currency forward contracts not designated as cash flow hedges. As of December 31, 2021, the total notional amount of the foreign currency forward contracts was $19.0 million (CAD$24.1 million), and all foreign currency forward contracts were designated as cash flow hedges. As of December 31, 2022, the Company’s foreign currency forward contracts mature at various dates through October 2023 and are subject to an enforceable master netting arrangement. As of December 31, 2022, the interest rate swap, which effectively converts a portion of the Company’s variable-rate debt to fixed-rate debt, was designated as cash flow hedge. The Company receives floating interest payments monthly based on the SOFR and pays a fixed rate of 1.941% to the counterparty. As of December 31, 2022, the total notional amount was $26.7 million, which amortizes ratably on a monthly basis to zero by the April 2024 maturity date. On August 9, 2022, the Company entered into an interest rate swap transaction which will begin April 3, 2023 at a notional amount of $15.0 million, which will amortize ratably on a monthly basis to zero by the April 2028 maturity date. The Company will receive floating interest payments monthly based on the 30 day Average SOFR and will pay a fixed rate of 2.96% to the counterparty.

See Note 18, “Accumulated Other Comprehensive Loss” for additional quantitative information regarding foreign currency forward contract gains and losses. 12. STOCKHOLDERS’ EQUITY: At-the-Market Offering On September 2, 2022, the Company entered into an Open Market Sale Agreement (the “At-the-Market Offering”) with Jefferies LLC (“Jefferies”), pursuant to which the Company may issue and sell shares of its common stock, par value $0.01 per share, having aggregate offering sales proceeds of up to $50 million (the “Shares”) from time to time through Jefferies as its sales agent. The Company may sell the Shares in amounts and at times to be determined by the Company from time to time subject to the terms and conditions of the At-the-Market Offering, but it has no obligation to sell any of the Shares under the At-the-Market Offering. The Shares to be sold under the At-the-Market Offering, if any, will be offered and sold pursuant to the Company’s shelf registration statement on Form S‑3 (File No. 333‑249637) filed with the Securities and Exchange Commission, which became effective on November 3, 2020, and the prospectus supplement dated September 2, 2022 filed by the Company. The Company will pay Jefferies a cash commission of up to 3.0% of gross proceeds from the sale of the Shares pursuant to the At-the-Market Offering. The Company has also agreed to provide Jefferies with customary indemnification and contribution rights. No proceeds were raised under the At-the-Market Offering during the year ended December 31, 2022. F- 23 Table of Contents 13. RETIREMENT PLANS: Defined Contribution Plan The Company has a defined contribution retirement plan that covers substantially all of its employees and provides for a Company match of up to 50% of the first 8% of employee contributions to the plan, subject to certain limitations. The defined contribution retirement plan offers 25 investment options. ParkUSA had a defined contribution retirement plan that covered substantially all of its employees and provided for a match of up to 100% of the first 4% of employee contributions to the plan, subject to certain limitations. After the acquisition of ParkUSA on October 5, 2021, employees of ParkUSA continued to contribute to this plan until it was merged into the Company’s plan effective December 31, 2021. Defined Benefit Plans The Company has two noncontributory defined benefit plans. Effective 2001, both plans were frozen and participants were fully vested in their accrued benefits as of the date each plan was frozen. No additional participants can be added to the plans and no additional service can be earned by participants subsequent to the date the plans were frozen. The funding policy for both of these plans is based on current plan costs plus amortization of the unfunded plan liability. As of December 31, 2022 and 2021, the Company had recorded, in accordance with the actuarial valuations, an accrued pension asset (liability) of $0.1 million and $(1.0) million, respectively, in Other long-term assets and Other long-term liabilities, respectively, and an unrecognized actuarial loss, net of tax, of $1.5 million, in both 2022 and 2021, in Accumulated other comprehensive loss. Additionally, as of December 31, 2022 and 2021, the projected and accumulated benefit obligation was $4.8 million and $6.1 million, respectively, and the fair value of plan assets was $4.9 million and $5.1 million, respectively. The net periodic benefit cost was $0.1 million for each of the years ended December 31, 2022 and 2021, and approximately $0 for the year ended December 31, 2020. The weighted-average discount rates used to measure the projected benefit obligation were 4.89% and 2.41% as of December 31, 2022 and 2021, respectively. The plan assets are invested in pooled separate accounts stated at fair value based on the daily net asset value of the account and are therefore not categorized in the fair value hierarchy. The expected weighted-average long-term rate of return on plan assets was 7.0% as of December 31, 2022 and 2021. Non-qualified Retirement Savings Plan The Company has a deferred compensation plan that covered officers and selected highly compensated employees until it was frozen in 2016. As of December 31, 2022 and 2021, deferred compensation plan balances of $3.6 million and $4.3 million, respectively, were recorded in Other assets and Other long-term liabilities. Total expense for all retirement plans for the years ended December 31, 2022, 2021, and 2020 was $2.2 million, $1.8 million, and $1.6 million, respectively, and is primarily related to the defined contribution plan. 14. SHARE-BASED COMPENSATION: The Company has one active stock incentive plan for employees and directors, the 2022 Stock Incentive Plan, which provides for awards of stock options to purchase shares of common stock, stock appreciation rights, restricted and unrestricted shares of common stock, RSUs, and PSAs. In addition, the Company has one inactive stock incentive plan, the 2007 Stock Incentive Plan, under which previously granted awards remain outstanding. F- 24 Table of Contents The following table summarizes share-based compensation expense recorded (in thousands): 2022 Year Ended December 31, 2021 2020 Cost of sales Selling, general, and administrative expense Total $ $ 1,320 $ 2,382 3,702 $ 1,003 $ 2,213 3,216 $ 822 2,266 3,088 There were 873,402 shares of common stock available for future issuance under the Company’s stock incentive plan as of December 31, 2022, assuming the outstanding PSAs vest at the target level of 100%. Stock Options Awards The Company’s stock incentive plan provides that options become exercisable according to vesting schedules and terminate according to the terms of the grant. There were no options granted during the years ended December 31, 2022, 2021, or 2020. During the year ended December 31, 2020, 24,000 stock options at a weighted-average exercise price of $24.15 were exercised. The total intrinsic value of options exercised during the year ended December 31, 2020 was $0.1 million. There were no options exercised during the years ended December 31, 2022 or 2021. As of December 31, 2022 and 2021, there were no stock options outstanding. Restricted Stock Units and Performance Share Awards The Company’s stock incentive plan provides for equity instruments, such as RSUs and PSAs, which grant the right to receive a specified number of shares at specified times. RSUs and PSAs are service-based awards that vest according to the terms of the grant. PSAs have performance-based payout conditions. The following table summarizes the Company’s RSU and PSA activity: Unvested RSUs and PSAs as of December 31, 2021 RSUs and PSAs granted Unvested RSUs and PSAs canceled RSUs and PSAs vested (2) Unvested RSUs and PSAs as of December 31, 2022 (1) The number of PSAs disclosed in this table are at the target level of 100%. Number of RSUs and PSAs (1) Weighted-Average Grant Date Fair Value 161,131 $ 116,622 (8,248) (68,581) 200,924 30.26 30.68 31.18 29.29 30.80 (2) For the PSAs vested on March 31, 2022, the actual number of common shares that were issued was determined by multiplying the PSAs at the target level of 100%, as disclosed in this table, by a payout percentage based on the performance-based conditions achieved. The payout percentage was 141% for the 2020-2021 performance period and 93% for the 2021 performance period. The unvested balance of RSUs and PSAs as of December 31, 2022 includes approximately 149,000 PSAs at the target level of 100%. The vesting of these awards is subject to the achievement of specified performance-based conditions, and the actual number of common shares that will ultimately be issued will be determined by multiplying this number of PSAs by a payout percentage ranging from 0% to 200%. The weighted-average grant date fair value of RSUs and PSAs granted during the years ended December 31, 2022, 2021, and 2020 was $30.68, $33.30, and $26.61, respectively. The total fair value of RSUs and PSAs vested during the years ended December 31, 2022, 2021, and 2020 was $2.4 million, $3.3 million, and $2.0 million, respectively. Based on the estimated level of achievement of the performance targets associated with the PSAs as of December 31, 2022, unrecognized compensation expense related to the unvested portion of the Company’s RSUs and PSAs was $3.5 million, which is expected to be recognized over a weighted-average period of 1.5 years. F- 25 Table of Contents Stock Awards For the years ended December 31, 2022, 2021, and 2020, stock awards of 11,380 shares, 12,606 shares, and 17,442 shares, respectively, were granted to non-employee directors, which vested immediately upon issuance. The Company recorded compensation expense based on the weighted-average fair market value per share of the awards on the grant date of $30.75 in 2022, $30.94 in 2021, and $25.81 in 2020. 15. COMMITMENTS AND CONTINGENCIES: Portland Harbor Superfund Site In December 2000, a section of the lower Willamette River known as the Portland Harbor Superfund Site was included on the National Priorities List at the request of the United States Environmental Protection Agency (“EPA”). While the Company’s Portland, Oregon manufacturing facility does not border the Willamette River, an outfall from the facility’s stormwater system drains into a neighboring property’s privately owned stormwater system and slip. Also in December 2000, the Company was notified by the EPA and the Oregon Department of Environmental Quality (“ODEQ”) of potential liability under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). A remedial investigation and feasibility study of the Portland Harbor Superfund Site was directed by a group of 14 potentially responsible parties known as the Lower Willamette Group under agreement with the EPA. The EPA finalized the remedial investigation report in February 2016, and the feasibility study in June 2016, which identified multiple remedial alternatives. In January 2017, the EPA issued its Record of Decision selecting the remedy for cleanup at the Portland Harbor Superfund Site, which it believes will cost approximately $1 billion at net present value and 13 years to complete. The EPA has not yet determined who is responsible for the costs of cleanup or how the cleanup costs will be allocated among the more than 150 potentially responsible parties. Because of the large number of potentially responsible parties and the variability in the range of remediation alternatives, the Company is unable to estimate an amount or an amount within a range of costs for its obligation with respect to the Portland Harbor Superfund Site matters, and no further adjustment to the Consolidated Financial Statements has been recorded as of the date of this filing. The ODEQ is separately providing oversight of voluntary investigations and source control activities by the Company involving the Company’s site, which are focused on controlling any current “uplands” releases of contaminants into the Willamette River. No liabilities have been established in connection with these investigations because the extent of contamination and the Company’s responsibility for the contamination have not yet been determined. Concurrent with the activities of the EPA and the ODEQ, the Portland Harbor Natural Resources Trustee Council (“Trustees”) sent some or all of the same parties, including the Company, a notice of intent to perform a Natural Resource Damage Assessment (“NRDA”) for the Portland Harbor Superfund Site to determine the nature and extent of natural resource damages under CERCLA Section 107. The Trustees for the Portland Harbor Superfund Site consist of representatives from several Northwest Indian Tribes, three federal agencies, and one state agency. The Trustees act independently of the EPA and the ODEQ. The Trustees have encouraged potentially responsible parties to voluntarily participate in the funding of their injury assessments and several of those parties have agreed to do so. In June 2014, the Company agreed to participate in the injury assessment process, which included funding $0.4 million of the assessment. The Company has not assumed any additional payment obligations or liabilities with the participation with the NRDA, nor does the Company expect to incur significant future costs in the resolution of the NRDA. In January 2017, the Confederated Tribes and Bands of the Yakama Nation, a Trustee until they withdrew from the council in 2009, filed a complaint against the potentially responsible parties including the Company to recover costs related to their own injury assessment and compensation for natural resources damages. The case has been stayed until January 2025, and the Company does not have sufficient information at this time to determine the likelihood of a loss in this matter or the amount of damages that could be allocated to the Company. The Company has insurance policies for defense costs, as well as indemnification policies it believes will provide reimbursement for the remediation assessed. However, the Company can provide no assurance that those policies will cover all of the costs which the Company may incur. F- 26 Table of Contents All Sites The Company operates its facilities under numerous governmental permits and licenses relating to air emissions, stormwater runoff, and other environmental matters. The Company’s operations are also governed by many other laws and regulations, including those relating to workplace safety and worker health, principally the Occupational Safety and Health Act and regulations there under which, among other requirements, establish noise and dust standards. The Company believes it is in material compliance with its permits and licenses and these laws and regulations, and the Company does not believe that future compliance with such laws and regulations will have a material adverse effect on its financial position, results of operations, or cash flows. Other Contingencies and Legal Proceedings From time to time, the Company is party to a variety of legal actions, including claims, suits, complaints, and investigations arising out of the ordinary course of its business. The Company maintains insurance coverage against potential claims in amounts that are believed to be adequate. To the extent that insurance does not cover legal, defense, and indemnification costs associated with a loss contingency, the Company records accruals when such losses are considered probable and reasonably estimable. The Company believes that it is not presently a party to legal actions, the outcomes of which would have a material adverse effect on its business, financial condition, results of operations, or cash flows. On April 21, 2019, there was an accidental fire at the Company’s Saginaw, Texas facility which resulted in damage to the coatings building. There were no injuries, but the ability to coat at this facility was impaired while the Company repaired the damage. The Company’s other production locations were deployed to absorb the lost production that resulted. The Company has insurance coverage in place covering, among other things, business interruption and property damage up to certain specified amounts, and worked with its insurance company to restore the facility to full service as safely and quickly as possible. The Saginaw facility resumed operations in October 2019. The Company received $1.4 million of business interruption insurance recovery (net of incremental production costs) during the year ended December 31, 2020 which was recorded in Cost of sales. Commitments As of December 31, 2022, the Company’s commitments include approximately $1.1 million remaining relating to its investment in a new reinforced concrete pipe mill for which the Company has not yet received the equipment. Guarantees The Company has entered into certain letters of credit that total $1.1 million as of December 31, 2022. The letters of credit relate to workers’ compensation insurance. 16. REVENUE: Net sales by geographic region, based on the location of the customer, were as follows (in thousands): Net sales by geographic region: United States Canada Total 2022 Year Ended December 31, 2021 2020 $ $ 423,961 $ 33,704 457,665 $ 313,729 $ 19,584 333,313 $ 254,956 30,951 285,907 One SPP customer accounted for 12%, 12%, and 16% of total net sales for the years ended December 31, 2022, 2021, and 2020, respectively. No Precast customer accounted for more than 10% of total net sales for the years ended December 31, 2022, 2021, and 2020. Revisions in contract estimates resulted in an increase (decrease) in SPP net sales of $(0.6) million, $2.0 million, and $2.2 million for the years ended December 31, 2022, 2021, and 2020, respectively. F- 27 Table of Contents Disaggregation of Revenue The following table disaggregates revenue by recognition over time or at a point in time, as the Company believes it best depicts how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors (in thousands): Over time (Engineered Steel Pressure Pipe) Point in time (Precast Infrastructure and Engineered Systems) Net sales Contract Assets and Liabilities 2022 Year Ended December 31, 2021 2020 $ $ 307,572 $ 150,093 457,665 $ 259,823 $ 73,490 333,313 $ 241,690 44,217 285,907 The difference between the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and billings. The changes in the contract assets and contract liabilities balances during the years ended December 31, 2022, 2021, and 2020 were not materially affected by any other factors. The Company recognized revenue that was included in the contract liabilities balance at the beginning of each period of $2.7 million, $6.2 million, and $12.3 million during the years ended December 31, 2022, 2021, and 2020, respectively. Backlog Backlog represents the balance of remaining performance obligations under signed contracts for SPP water infrastructure steel pipe products for which revenue is recognized over time. As of December 31, 2022, backlog was $274 million. The Company expects to recognize approximately 66% of the remaining performance obligations in 2023 and 34% in 2024. 17.

The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred income tax liabilities, projected future taxable income, taxable income in carryback periods, and tax planning strategies in making this assessment. The Company believes it is more likely than not it will realize the benefits of its deductible differences as of December 31, 2022, net of any valuation allowance. As of December 31, 2022, the Company continues to maintain a valuation allowance on federal tax credits, capital loss carryforwards, and select state jurisdictions. F- 29 Table of Contents As of December 31, 2022, the Company had approximately $0.4 million of federal income tax credit carryforwards, which expire on various dates between 2023 and 2026, and $0.8 million of capital loss carryforwards, which expire in 2023. As of December 31, 2022, the Company also had approximately $18.4 million of state net operating loss carryforwards, which expire on various dates between 2022 and 2038, and state income tax credit carryforwards of $4.4 million, which began to expire in 2022. As of December 31, 2022, the Company also had approximately $6.0 million of foreign net operating loss carryforwards, which expire on various dates between 2023 and 2030. The Company files income tax returns in the United States Federal jurisdiction, in a limited number of foreign jurisdictions, and in many state jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, or foreign income tax examinations for years before 2018. A summary of the changes in the unrecognized income tax benefits is presented below (in thousands): 2022 Year Ended December 31, 2021 2020 Unrecognized income tax benefits, beginning of year Increases for positions taken in prior years Unrecognized income tax benefits, end of year $ $ 4,366 $ 106 4,472 $ 4,350 $ 16 4,366 $ 4,350 - 4,350 The Company does not believe it is reasonably possible that the total amounts of unrecognized income tax benefits will change in the following twelve months; however, actual results could differ from those currently expected. Effectively all of the unrecognized income tax benefits would affect the Company’s effective income tax rate if recognized at some point in the future. The Company recognizes interest and penalties related to uncertain income tax positions in Income tax expense. As of December 31, 2022 and 2021, the Company had $0.1 million and approximately $0, respectively, of accrued interest related to uncertain income tax positions. Total interest for uncertain income tax positions did not change materially in 2022, 2021, or 2020. 18.
