NORTHWEST PIPE COMPANY AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. | Organization and Basis of Presentation

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.

In addition to being the largest manufacturer of engineered steel water pipeline systems in North America, the Company manufactures high-quality precast and reinforced concrete products; water, wastewater, and stormwater equipment; 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.

The Condensed 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.

Effective in the fourth quarter of 2021, as a result of the acquisition of Park Environmental Equipment, LLC (“ParkUSA”), the Company revised its historical one segment position and identified the new operating segments, SPP and Precast, to align with changes made in its internal management structure and its reporting structure of financial information used to assess performance and allocate resources. See Note 12, “Segment Information” for detailed descriptions of these segments. As a result, certain amounts from the prior year financial statements have been reclassified in order to conform to the current year presentation.

The accompanying unaudited interim Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. The financial information as of December 31, 2021 is derived from the audited Consolidated Financial Statements presented in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2021 (“2021 Form 10‑K”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission and the accounting standards for interim financial statements. In the opinion of management, the accompanying Condensed Consolidated Financial Statements include all adjustments necessary (which are of a normal and recurring nature) for the fair statement of the results of the interim periods presented. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto together with management’s discussion and analysis of financial condition and results of operations contained in the Company’s 2021 Form 10‑K.

Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2022, particularly in light of the coronavirus disease 2019 pandemic and its effects on the domestic and global economies.

2. | Business Combination

On October 5, 2021, the Company completed the acquisition of 100% of Park Environmental Equipment, LLC for a purchase price of approximately $88.4 million in cash, subject to a post-closing adjustment based on changes in net working capital, and 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.

Table of Contents

The following table summarizes the purchase consideration and fair value of the assets acquired and liabilities assumed as of October 5, 2021 (in thousands):

Assets |  |  |  |
Cash and cash equivalents |  | $ | 278 |
Trade and other receivables |  |  | 11,034 |
Inventories |  |  | 12,773 |
Prepaid expenses and other |  |  | 293 |
Property and equipment |  |  | 8,076 |
Operating lease right-of-use assets |  |  | 58,301 |
Intangible assets |  |  | 31,000 |
Deferred income taxes |  |  | 347 |
Total assets acquired |  |  | 122,102 |
Liabilities |  |  |  |
Accounts payable |  |  | 2,029 |
Accrued liabilities |  |  | 4,067 |
Operating lease liabilities |  |  | 58,301 |
Total liabilities assumed |  |  | 64,397 |
Goodwill |  |  | 30,699 |
Total purchase consideration |  | $ | 88,404 |

The tangible and intangible assets acquired and liabilities assumed were recognized based on their estimated fair values on the acquisition date, with the excess purchase consideration recorded as goodwill. The asset and liability fair value measurements primarily related to inventories, identifiable intangible assets, deferred income taxes, accrued liabilities, and goodwill, are preliminary and subject to change as additional information is obtained. The acquisition accounting will be finalized as soon as practicable within the measurement period, but not later than one year following the acquisition date.

The following table summarizes the components of the intangible assets acquired and their estimated useful lives:

|  | Estimated Useful Life |  |  | Fair Value |
|  | (In years) |  |  | (In thousands) |
Customer relationships |  |  | 10.0 |  |  | $ | 19,800 |
Trade names and trademarks |  |  | 10.0 |  |  |  | 9,600 |
Patents |  |  | 21.0 |  |  |  | 1,300 |
Backlog |  |  | 0.6 |  |  |  | 300 |
Total intangible assets |  |  | 10.2 |  |  | $ | 31,000 |

Goodwill arose from the acquisition of an assembled workforce, expansion of product offerings, and management’s industry know-how, and is expected to be deductible for tax purposes.

The Company incurred transaction costs associated with this acquisition of approximately $0 and $0.1 million during the three months ended March 31, 2022 and 2021, respectively. These transaction costs are included in Selling, general, and administrative expense in the Condensed Consolidated Statements of Operations.

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 of the year prior to the acquisition (in thousands):

|  | Three Months Ended March 31, 2021 |
Net sales |  | $ | 85,530 |
Net income |  |  | 3,972 |

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 acquisition of ParkUSA had occurred on January 1 of the 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. The pro forma amounts have been calculated after applying the Company’s accounting policies and adjusting the results of ParkUSA 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 year prior to the acquisition. Adjustments also include an increase of interest expense as if the Company’s debt obtained in connection with the acquisition of ParkUSA had been outstanding since January 1 of the year prior to the acquisition. The provision for income taxes has also been adjusted for all periods, based upon the foregoing adjustments to historical results.

3. | Inventories

Inventories consist of the following (in thousands):

|  | March 31, 2022 |  |  | December 31, 2021 |
Raw materials |  | $ | 47,297 |  |  | $ | 44,697 |
Work-in-process |  |  | 2,905 |  |  |  | 3,018 |
Finished goods |  |  | 10,620 |  |  |  | 10,096 |
Supplies |  |  | 1,886 |  |  |  | 1,840 |
Total inventories |  | $ | 62,708 |  |  | $ | 59,651 |

4. | 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.

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 March 31, 2022 |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Financial assets: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Deferred compensation plan |  | $ | 4,085 |  |  | $ | 3,567 |  |  | $ | 518 |  |  | $ | - |
Foreign currency forward contracts |  |  | 4 |  |  |  | - |  |  |  | 4 |  |  |  | - |
Total financial assets |  | $ | 4,089 |  |  | $ | 3,567 |  |  | $ | 522 |  |  | $ | - |
Financial liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Foreign currency forward contracts |  | $ | (814 | ) |  | $ | - |  |  | $ | (814 | ) |  | $ | - |
As of December 31, 2021 |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Financial assets: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Deferred compensation plan |  | $ | 4,321 |  |  | $ | 3,830 |  |  | $ | 491 |  |  | $ | - |
Foreign currency forward contracts |  |  | 17 |  |  |  | - |  |  |  | 17 |  |  |  | - |
Total financial assets |  | $ | 4,338 |  |  | $ | 3,830 |  |  | $ | 508 |  |  | $ | - |
Financial liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Foreign currency forward contracts |  | $ | (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 Condensed Consolidated Balance Sheets.

The Company’s foreign currency forward contracts 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. Foreign currency forward contracts are presented at their gross fair values. Foreign currency forward contract assets are included within Prepaid expenses and other and foreign currency forward contract liabilities are included within Accrued liabilities in the Condensed Consolidated Balance Sheets.

The net carrying amounts of cash and cash equivalents, trade and other receivables, accounts payable, accrued liabilities, and borrowings on the line of credit approximate fair value due to the short-term nature of these instruments.

5. | Derivative Instruments and Hedging Activities

For each foreign currency forward contract 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 foreign currency forward contracts to specific firm commitments or forecasted transactions and designating the foreign currency forward contracts as cash flow hedges. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the foreign currency forward contracts 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 Condensed Consolidated Statements of Comprehensive Income. If it is determined that a foreign currency forward contract 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 foreign currency forward contract prospectively.

10

Table of Contents

As of March 31, 2022, the total notional amount of the foreign currency forward contracts designated as cash flow hedges was $15.9 million (CAD$19.8 million) and $9.9 million (EUR$9.0 million). As of December 31, 2021, the total notional amount of the foreign currency forward contracts designated as cash flow hedges was $19.0 million (CAD$24.1 million). As of March 31, 2022, the Company’s foreign currency forward contracts mature at various dates through April 2023 and are subject to an enforceable master netting arrangement.

As of March 31, 2022 and December 31, 2021, all foreign currency forward contracts were designated as cash flow hedges. Gains (losses) recognized in Net sales from foreign currency forward contracts not designated as hedging instruments were approximately $0 for the three months ended March 31, 2022 and 2021. There were no gains (losses) recognized in Property and equipment from foreign currency forward contracts not designated as hedging instruments for the three months ended March 31, 2022 and 2021. As of March 31, 2022, unrealized pretax losses on outstanding foreign currency forward contracts in Accumulated other comprehensive loss was $0.6 million, of which $0.2 million is expected to be reclassified to Net sales within the next twelve months as a result of underlying hedged transactions also being recorded in Net sales and $0.2 million is expected to be reclassified to Property and equipment within the next twelve months as a result of underlying hedged transactions also being recorded in Property and equipment. See Note 10, “Accumulated Other Comprehensive Loss” for additional information regarding foreign currency forward contract gains and losses.

On March 23, 2022, the Company entered into an interest rate swap transaction which will begin April 29, 2022, at a notional amount of $40.0 million, a fixed rate of 1.94%, and a maturity date of April 30, 2024.

6. | Share-based Compensation

The Company has one active stock incentive plan for employees and directors, the 2007 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, restricted stock units (“RSUs”), and performance share awards (“PSAs”).

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 RSUs and 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.

The following table summarizes share-based compensation expense recorded (in thousands):

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Cost of sales |  | $ | 240 |  |  | $ | 230 |
Selling, general, and administrative expense |  |  | 395 |  |  |  | 467 |
Total |  | $ | 635 |  |  | $ | 697 |

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 over a specified period of time. RSUs and PSAs are service-based awards that vest according to the terms of the grant. PSAs have performance-based payout conditions.

11

Table of Contents

The following table summarizes the Company’s RSU and PSA activity:

|  | Number of RSUs and PSAs (1) |  |  | Weighted-Average Grant Date Fair Value |
Unvested RSUs and PSAs as of December 31, 2021 |  |  | 161,131 |  |  | $ | 30.26 |
RSUs and PSAs vested (2) |  |  | (68,581 | ) |  |  | 29.29 |
Unvested RSUs and PSAs as of March 31, 2022 |  |  | 92,550 |  |  |  | 30.98 |

(1) | The number of PSAs disclosed in this table are at the target level of 100%.
(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 March 31, 2022 includes approximately 69,000 PSAs at a target level of performance. 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%.

Based on the estimated level of achievement of the performance targets associated with the PSAs, as of March 31, 2022, unrecognized compensation expense related to the unvested portion of the Company’s RSUs and PSAs was $2.0 million, which is expected to be recognized over a weighted-average period of 1.5 years.

7. | 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 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 Condensed 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.

12

Table of Contents

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 Company does not have sufficient information 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.

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 involved in litigation relating to claims arising out of its operations in the normal 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 litigation, the outcome of which would have a material adverse effect on its business, financial condition, results of operations, or cash flows.

Commitments

As of March 31, 2022, the Company’s commitments include approximately $10 million 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 March 31, 2022. The letters of credit relate to workers’ compensation insurance.

8. | Revenue

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.

13

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.

Revisions in contract estimates resulted in an increase (decrease) in SPP net sales of $(0.8) million and $1.3 million for the three months ended March 31, 2022 and 2021, respectively.

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.

The Company 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.

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):

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Over time (Engineered Steel Pressure Pipe) |  | $ | 74,715 |  |  | $ | 60,057 |
Point in time (Precast Infrastructure and Engineered Systems) |  |  | 34,616 |  |  |  | 12,254 |
Net sales |  | $ | 109,331 |  |  | $ | 72,311 |

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. The Company recognized revenue that was included in the contract liabilities balance at the beginning of each period of $1.6 million and $4.7 million during the three months ended March 31, 2022 and 2021, 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 March 31, 2022, backlog was approximately $200 million. The Company expects to recognize approximately 65% of the remaining performance obligations in 2022, 32% in 2023, and the balance thereafter.

9. | Income Taxes

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 2017.

The Company recorded income tax expense at an estimated effective income tax rate of 27.4% and 21.7% for the three months ended March 31, 2022 and 2021, respectively. The Company’s estimated effective income tax rate for the three months ended March 31, 2022 was primarily impacted by non-deductible permanent differences. The Company’s estimated effective income tax rate for the three months ended March 31, 2021 was primarily impacted by the tax windfalls recognized upon the vesting of equity awards.

10. | Accumulated Other Comprehensive Loss

11. | Net Income per Share

Basic net income per share is computed by dividing 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):

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Net income |  | $ | 3,559 |  |  | $ | 2,175 |

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 high-quality precast and reinforced concrete products; water, wastewater, and stormwater equipment; 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.

In October 2021 we acquired Park Environmental Equipment, LLC, a precast concrete and steel fabrication-based company in Texas that develops and manufactures water, wastewater, and environmental solutions. Effective in the fourth quarter of 2021, as a result of the acquisition of ParkUSA, we revised our historical one segment position and identified the new operating segments, Engineered Steel Pressure Pipe (“SPP”) and Precast Infrastructure and Engineered Systems (“Precast”), to align with changes made in our internal management structure and our reporting structure of financial information used to assess performance and allocate resources. For detailed descriptions of these segments, see Note 12 of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q.

Our Current Economic Environment

We operate our business with a long-term time horizon, as our SPP projects are often planned for many years in advance, and are sometimes part of 50‑year build-out plans. Long-term demand for water infrastructure projects in the United States appears strong. However, in the near term, we expect that strained governmental and water agency budgets and financing along with increased manufacturing capacity from competition could impact the business. Additionally, we have started to experience effects of a 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 between 25% and 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 prices dropped significantly during the first quarter of 2022 from their peaks realized at the end of 2021, and subsequently began to rebound. Due to the length of lead times and production times for steel required to manufacture our products, the effects of these lower steel costs from purchases in the first quarter are yet to be realized in our financial results.

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 5% 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.

Demand for our Precast products is generally influenced by general economic conditions such as housing starts, population growth, and interest rates. According to the United States Census Bureau, housing starts are expected to increase to 1.8 million in 2022 during which period the population of the United States is expected to increase by approximately 2 million people. In March 2022, the Federal Reserve approved a 0.25 percentage point increase to the Federal funds rate, and is expected to continue to increase this benchmark rate through 2022 and into 2023. While this is expected to temper long-term demand for housing, the immediate impacts are made uncertain by pent-up demand for housing as well as labor and commodity shortages currently limiting the supply of new homes.

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 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 unknown. 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.

Three Months Ended March 31, 2022 Compared to Three Months Ended March 31, 2021

Net sales. Net sales increased 51.2% to $109.3 million in the first quarter of 2022 compared to $72.3 million in the first quarter of 2021.

SPP net sales increased 24.4% to $74.7 million in the first quarter of 2022 compared to $60.0 million in the first quarter of 2021 driven by an 85% increase in selling price per ton due to increased materials costs and changes in product mix, partially offset by a 33% 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 182.5% to $34.6 million in the first quarter of 2022 compared to $12.3 million in the first quarter of 2021 primarily due to the ParkUSA operations acquired in October 2021, which contributed $19.7 million in net sales during the first quarter of 2022, as well as a 22% increase in net sales at the Geneva Pipe and Precast Company (“Geneva”) operations due to a 35% increase in selling prices due to the high demand for our concrete products coupled with increased material costs, partially offset by a 10% decrease in volume shipped due to the changes in product mix.

Table of Contents

Gross profit. Gross profit increased 68.5% to $14.8 million (13.5% of net sales) in the first quarter of 2022 compared to $8.8 million (12.1% of net sales) in the first quarter of 2021.

SPP gross profit remained relatively flat at $7.2 million (9.6% of SPP net sales) in the first quarter of 2022 compared to $7.2 million (11.9% of SPP net sales) in the first quarter of 2021 due to the combination of changes in product mix and pressure on project pricing. SPP gross profit in the first quarter of 2022 was reduced, in part, as a result of a product liability settlement reserve recorded in the quarter.

Precast gross profit increased 368.7% to $7.6 million (21.9% of Precast net sales) in the first quarter of 2022 compared to $1.6 million (13.2% of Precast net sales) in the first quarter of 2021 due to contributions from the ParkUSA operations, as well as improved pricing at the Geneva operations.

Selling, general, and administrative expense. Selling, general, and administrative expense increased 60.7% to $9.4 million (8.5% of net sales) in the first quarter of 2022 compared to $5.8 million (8.0% of net sales) in the first quarter of 2021. The increase in selling, general, and administrative expense was primarily due to the acquired ParkUSA operations, including $1.3 million in higher compensation-related expense and $0.8 million in higher amortization expense. We also incurred an additional $1.0 million in higher compensation-related expense and $0.4 million in higher professional fees compared to the first quarter of 2021.

Income taxes. Income tax expense was $1.3 million in the first quarter of 2022 (an effective income tax rate of 27.4%) compared to $0.6 million in the first quarter of 2021 (an effective income tax rate of 21.7%). The estimated effective income tax rate for the first quarter of 2022 was impacted by non-deductible permanent differences. The estimated effective income tax rate for the first quarter of 2021 was impacted by the tax windfalls recognized upon the vesting of equity awards. The estimated effective income tax rate can change significantly depending on the relationship of permanent income tax differences and tax credits to estimated pre-tax income or loss and the changes in valuation allowances. Accordingly, the comparison of estimated 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 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 (together, the “Amended Credit Agreement”). From time to time our long-term capital needs may be met through the issuance of long-term debt or additional 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 three months ended March 31, 2022 and 2021 are presented in our Condensed Consolidated Statements of Cash Flows contained in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q, and are further discussed below. We are actively managing the business to maintain cash flow and believe we have liquidity to meet our anticipated funding requirements and other near-term obligations.

As of March 31, 2022, our working capital (current assets minus current liabilities) was $171.5 million compared to $164.1 million as of December 31, 2021. Cash and cash equivalents totaled $3.3 million and $3.0 million as of March 31, 2022 and December 31, 2021, respectively.

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 March 31, 2022, we had $90.3 million of outstanding revolving loan borrowings, $97.3 million of operating lease liabilities, and $2.4 million of finance lease liabilities.

Net Cash Provided by (Used in) Operating Activities

Net cash provided by (used in) operating activities was $1.6 million in the first quarter of 2022 compared to $(0.6) million in the first quarter of 2021. Net income, adjusted for non-cash items, provided $8.8 million of operating cash flow in the first quarter of 2022 compared to $6.1 million of operating cash flow in the first quarter of 2021. The net change in working capital used was $7.2 million of operating cash flow in the first quarter of 2022 compared to $6.7 million of operating cash flow in the first quarter of 2021.

Net Cash Used in Investing Activities

Net cash used in investing activities was $4.4 million in the first quarter of 2022 compared to $1.8 million in the first quarter of 2021. Capital expenditures were $4.4 million in the first quarter of 2022 compared to $1.9 million in the first quarter of 2021, which was primarily for standard capital replacement. We currently expect capital expenditures in 2022 to be approximately $26 million to $30 million, which includes an approximately $13 million of additional investment in a new reinforced concrete pipe mill and the remainder primarily for standard capital replacement.

Net Cash Provided by (Used in) Financing Activities

Net cash provided by (used in) financing activities was $3.1 million in the first quarter of 2022 compared to $(5.7) million in the first quarter of 2021. Net borrowings on the line of credit were $3.5 million in the first quarter of 2022 compared to $0 in the first quarter of 2021. Net repayments on long-term debt were $0 in the first quarter of 2022 compared to $5.4 million in the first quarter of 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 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 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 registration statement, which replaced the registration statement on Form S‑3 that expired on September 15, 2020, 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 Q1 Form 10‑Q, 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” in our 2021 Form 10‑K.

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 March 31, 2022 under the Amended Credit Agreement, we had $90.3 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $34 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 including certain London Interbank Offered Rate (“LIBOR”) transition provisions, either: (i) Base Rate (as defined in the Amended Credit Agreement) plus the Applicable Margin; (ii) LIBOR plus the Applicable Margin; or (iii) the daily one month LIBOR plus the Applicable Margin. The “Applicable Margin” is 1.75% to 2.25%, depending on our Senior Leverage Ratio (as defined in the Amended Credit Agreement). Interest on outstanding revolving loans is payable quarterly. 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 quarterly 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 March 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 March 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.

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 13 of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements included in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our Condensed 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, inventories, property and equipment, including depreciation and valuation, goodwill, intangible assets, including amortization, share-based compensation, allowance for doubtful accounts, income taxes, and litigation and other contingencies. Actual results may differ from these estimates under different assumptions or conditions.

There have been no significant changes in our critical accounting estimates during the three months ended March 31, 2022 as compared to the critical accounting estimates disclosed in our 2021 Form 10‑K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For a discussion of our market risk associated with foreign currencies and interest rates, see Part II – Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” of our 2021 Form 10‑K.

Item 4. 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 (the “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 (the “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.

In connection with the preparation of this Quarterly Report on Form 10‑Q for the quarter ended March 31, 2022, our management, under the supervision and with the participation of our CEO and CFO, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2022. As a result of the assessment, our CEO and CFO have concluded that, as of March 31, 2022, our disclosure controls and procedures were effective.

As discussed in Note 2 of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q, we completed the acquisition of 100% of Park Environmental Equipment, LLC (“ParkUSA”) on October 5, 2021. As part of our post-closing integration activities, we are engaged in the process of assessing the internal controls of ParkUSA. We have begun to integrate policies, processes, people, technology, and operations for the post-acquisition combined company, and we will continue to evaluate the impact of any related changes to internal control over financial reporting. As permitted for newly acquired businesses by interpretive guidance issued by the staff of the SEC, management has excluded the internal control over financial reporting of ParkUSA from the evaluation of the effectiveness of our disclosure controls and procedures as of March 31, 2022. We have reported the operating results of ParkUSA in our condensed consolidated statements of operations and cash flows from the acquisition date through March 31, 2022. As of March 31, 2022, total assets related to ParkUSA represented approximately 16.1% of our total assets, recorded on a preliminary basis as the measurement period for the business combination remained open as of March 31, 2022. Revenues from ParkUSA represented approximately 18.0% of our total consolidated revenues for the three months ended March 31, 2022.

Changes in Internal Control over Financial Reporting

Except for changes in internal controls that we have made related to the integration of ParkUSA into the post-acquisition combined company, there were no significant changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II – OTHER INFORMATION

Item 1. Legal Proceedings

We are party to a variety of legal actions arising out of the ordinary course of business. Plaintiffs occasionally seek punitive or exemplary damages. We do not believe that such normal and routine litigation will have a material impact on our consolidated financial results. We are also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines, penalties, and other costs in substantial amounts. See Note 7 of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2022 Q1 Form 10‑Q.

Item 1A. Risk Factors

In addition to the other information set forth in this 2022 Q1 Form 10‑Q, the factors discussed in Part I – Item 1A. “Risk Factors” in our 2021 Form 10‑K could materially affect our business, financial condition, or operating results. The risks described in our 2021 Form 10‑K are not the only risks facing us. There are additional risks and uncertainties not currently known to us or that we currently deem to be immaterial, that may also materially adversely affect our business, financial condition, or operating results.
