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 12, “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.

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.

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, 2022 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, 2022 (“2022 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 2022 Form 10‑K.

Table of Contents

3.	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, the Second Amendment to Credit Agreement dated April 29, 2022, and the Third Amendment to Credit Agreement dated June 29, 2023 (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”), with an option for the Company to increase that amount by $50 million, subject to provisions of the Amended Credit Agreement. The Amended Credit Agreement will expire, and all obligations outstanding will mature, on June 29, 2028. The Company may prepay outstanding amounts in its discretion without penalty at any time, subject to applicable notice requirements.

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 3.00 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 $35 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 June 30, 2023.

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.

Line of Credit (Revolving and Swingline Loans)

As of June 30, 2023 under the Amended Credit Agreement, the Company had $70.1 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $54 million. As of December 31, 2022 under the Amended Credit Agreement, the Company had $83.7 million of outstanding revolving loan borrowings and $1.1 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 Secured Overnight Financing Rate (“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 June 30, 2023 and December 31, 2022, the weighted-average interest rate for outstanding borrowings was 7.16% and 6.07%, 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.

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 June 30, 2023
Financial assets:
Deferred compensation plan	$	3,762		$	3,253	$	509		$	-

Financial liabilities:
Foreign currency forward contracts	$	(80	)	$	-	$	(80	)	$	-

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 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 Condensed 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.

5.	Derivative Instruments and Hedging Activities

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.

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 Condensed 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.

Table of Contents

As of June 30, 2023, the total notional amount of the foreign currency forward contracts was $5.2 million (CAD$6.9 million) and $1.2 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, 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 June 30, 2023, the Company’s foreign currency forward contracts mature at various dates through September 2024 and are subject to an enforceable master netting arrangement.

The Company has entered into interest rate swaps which effectively convert a portion of its variable-rate debt to fixed-rate debt, and are designated as cash flow hedges. The Company receives floating interest payments monthly based on SOFR and pays a fixed rate of 1.941% to the counterparty on the total notional amount of $16.7 million and $26.7 million as of June 30, 2023 and December 31, 2022, respectively, 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 began April 3, 2023. The Company receives floating interest payments monthly based on the SOFR Average 30 day and pays a fixed rate of 2.96% to the counterparty on the total notional amount of $14.5 million as of June 30, 2023, which amortizes ratably on a monthly basis to zero by the April 2028 maturity date.

The following table summarizes the gains (losses) recognized on derivatives in the Condensed Consolidated Financial Statements (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Total	$	(202	)	$	21		$	(413	)	$	33

As of June 30, 2023, unrealized pretax gains on outstanding cash flow hedges in Accumulated other comprehensive loss was $0.7 million, of which approximately $0, approximately $0, and $0.6 million are expected to be reclassified to Net sales, Property and equipment, and Interest expense, respectively, within the next twelve months as a result of underlying hedged transactions also being recorded in these line items. See Note 10, “Accumulated Other Comprehensive Loss” for additional quantitative information regarding foreign currency forward contract and interest rate swap gains and losses.

6.	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, restricted stock units (“RSUs”), and performance share awards (“PSAs”). In addition, the Company has one inactive stock incentive plan, the 2007 Stock Incentive Plan, under which previously granted awards remain outstanding.

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.

Table of Contents

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

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022

Cost of sales	$	266	$	108	$	541	$	348

Total	$	1,314	$	673	$	2,304	$	1,308

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:

	Number of RSUs and PSAs (1)			Weighted-Average Grant Date Fair Value

Unvested RSUs and PSAs as of December 31, 2022		200,924		$	30.80
RSUs and PSAs granted		134,498			28.41
Unvested RSUs and PSAs canceled		(10,731	)		30.64
RSUs and PSAs vested (2)		(95,442	)		30.12
Unvested RSUs and PSAs as of June 30, 2023		229,249			29.69

(1)	The number of PSAs disclosed in this table are at the target level of 100%.

(2)	For the PSAs vested on March 31, 2023, 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 159% for the 2020-2022 performance period, 126% for the 2021-2022 performance period, and 132% for the 2022 performance period.

The unvested balance of RSUs and PSAs as of June 30, 2023 includes approximately 172,000 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%.

Based on the estimated level of achievement of the performance targets associated with the PSAs as of June 30, 2023, unrecognized compensation expense related to the unvested portion of the Company’s RSUs and PSAs was $5.8 million, which is expected to be recognized over a weighted-average period of 1.8 years.

Stock Awards

For the six months ended June 30, 2023 and 2022, stock awards of 15,904 shares and 11,380 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 $29.51 in 2023 and $30.75 in 2022.

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 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.

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.

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 thereunder 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.

Table of Contents

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.

Commitments

As of June 30, 2023, the Company’s commitments include approximately $1.2 million remaining relating to its investment in the primary component of the 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 June 30, 2023. 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. 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.

Revisions in contract estimates resulted in an increase (decrease) in SPP net sales of $(0.4) million and approximately $0 for the three and six months ended June 30, 2023, respectively and $0.4 million and $(0.4) million for the three and six months ended June 30, 2022, 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.

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 June 30,				Six Months Ended June 30,
	2023		2022		2023		2022

Over time (Engineered Steel Pressure Pipe)	$	77,255	$	77,068	$	140,801	$	151,783
Point in time (Precast Infrastructure and Engineered Systems)		39,117		41,454		74,668		76,070
Net sales	$	116,372	$	118,522	$	215,469	$	227,853

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 $5.6 million and $14.7 million during the three and six months ended June 30, 2023, respectively and $2.9 million and $2.7 million during the three and six months ended June 30, 2022, 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 June 30, 2023, backlog was $292 million. The Company expects to recognize approximately 46% of the remaining performance obligations in 2023, 46% in 2024, 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 2018.

The Company recorded income tax expense at an estimated effective income tax rate of 26.5% and 27.1% for the three and six months ended June 30, 2023, respectively and 26.1% and 26.4% for the three and six months ended June 30, 2022, respectively. The Company’s estimated effective income tax rates for the three and six months ended June 30, 2023 and 2022 were primarily impacted by non-deductible permanent differences.

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.

Table of Contents

Net income per basic and diluted weighted-average common share outstanding was calculated as follows (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022

Net income	$	7,448	$	9,673	$	9,810	$	13,232

Basic weighted-average common shares outstanding		10,000		9,918		9,970		9,900
Effect of potentially dilutive common shares (1)		66		50		111		71
Diluted weighted-average common shares outstanding		10,066		9,968		10,081		9,971

Diluted	$	0.74	$	0.97	$	0.97	$	1.33

(1)

The weighted-average number of antidilutive shares not included in the computation of diluted net income per share was approximately 5,000 and 3,000 for the three and six months ended June 30, 2022, respectively. There were no antidilutive shares for the three and six months ended June 30, 2023

Recent Accounting and Reporting Developments

There have been no developments to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company’s Condensed Consolidated Financial Statements and disclosures in Notes to Condensed Consolidated Financial Statements, from those disclosed in the Company’s 2022 Form 10‑K, except for the following.

Accounting Changes

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. The Company adopted ASU 2021‑08 on January 1, 2023 and the impact was not material to the Company’s financial position, results of operations, or cash flows.

Recent Accounting Standards

In March 2023, the FASB issued ASU No. 2023-01 “Leases (Topic 842): Common Control Arrangements” (“ASU 2023‑01”) which requires leasehold improvements associated with common control leases be (1) amortized by the lessee over the useful life of the leasehold improvements to the common control group as long as the lessee controls the use of the underlying asset through a lease and (2) accounted for as a transfer between entities under common control through an adjustment to equity if, and when, the lessee no longer controls the use of the underlying asset. ASU 2023‑01 is effective for the Company beginning January 1, 2024, including interim periods in 2024, 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.

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 Note 12, “Segment Information” of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2023 Q2 Form 10‑Q.

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 were at a seasonally adjusted annual rate of 1.4 million in June 2023 and December 2022, 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 impacts of 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 and we have experienced an improvement in recent short-term demand for our engineered steel pressure pipe. Medium-term demand prospects could be negatively impacted by recessionary economic forces or, conversely, positively impacted by increased funding expedited by the Bipartisan Infrastructure Deal (Infrastructure Investment and Jobs Act) and the Inflation Reduction Act.

Purchased steel typically represents approximately 25% to 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 2023, with prices increasing significantly in the first half of the year. The increased steel costs are expected to be realized in our financial results in the second half of the year and offset by increased average selling prices.

Economic uncertainty, including the impacts of raw material shortages, inflationary pressures, potential risks of a recession, and the continued disruptions to and volatility in the financial markets could have an adverse effect on our business. The extent of the impact of these environmental forces on our business will depend on future developments, which cannot be predicted. Additionally, we have experienced effects of recent 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.

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. We currently expect these disruptions to be limited to physical inventory counts, which have been required at greater frequency than desired in order to ensure the accuracy of our inventory quantities. Additionally, we have hired consultants to assist with improving the ERP system, business processes, and workflow design.

Three and Six Months Ended June 30, 2023 Compared to Three and Six Months Ended June 30, 2022

Net sales. Net sales decreased 1.8% to $116.4 million in the second quarter of 2023 compared to $118.5 million in the second quarter of 2022 and decreased 5.4% to $215.5 million in the first six months of 2023 compared to $227.9 million in the first six months of 2022.

SPP net sales were $77.3 million in the second quarter of 2023 compared to $77.1 million in the second quarter of 2022 and $140.8 million in the first six months of 2023 compared to $151.8 million in the first six months of 2022. The 0.2% increase in the second quarter of 2023 compared to the second quarter of 2022 was driven by a 7% increase in selling price per ton due to product mix, partially offset by a 6% decrease in tons produced resulting primarily from changes in project timing. The 7.2% decrease in the first six months of 2023 compared to the first six months of 2022 was driven by a 5% decrease in tons produced resulting primarily from changes in project timing and a 2% decrease in selling price per ton primarily due to decreased raw materials costs. Bidding activity, backlog, and production levels may vary significantly from period to period affecting sales volumes.

Precast net sales were $39.1 million in the second quarter of 2023 compared to $41.5 million in the second quarter of 2022 and $74.7 million in the first six months of 2023 compared to $76.1 million in the first six months of 2022. The 5.6% decrease in the second quarter of 2023 compared to the second quarter of 2022 was driven by a 13% decrease in volume shipped due to lower demand, partially offset by an 8% increase in selling prices due to increased materials costs. The 1.8% decrease in the first six months of 2023 compared to the first six months of 2022 was driven by a 21% decrease in volume shipped primarily due to lower demand, partially offset by a 23% increase in selling prices due to increased materials costs.

Gross profit. Gross profit decreased 6.6% to $22.5 million (19.3% of net sales) in the second quarter of 2023 compared to $24.1 million (20.3% of net sales) in the second quarter of 2022 and increased 0.5% to $39.1 million (18.1% of net sales) in the first six months of 2023 compared to $38.9 million (17.1% of net sales) in the first six months of 2022.

SPP gross profit increased 13.2% to $12.6 million (16.3% of SPP net sales) in the second quarter of 2023 compared to $11.1 million (14.4% of SPP net sales) in the second quarter of 2022 primarily due to changes in product mix. SPP gross profit increased 11.3% to $20.4 million (14.5% of SPP net sales) in the first six months of 2023 compared to $18.3 million (12.1% of SPP net sales) in the first six months of 2022 primarily due to a $2.0 million product liability settlement reserve recorded in the first quarter of 2022.

Precast gross profit decreased 23.6% to $9.9 million (25.3% of Precast net sales) in the second quarter of 2023 compared to $13.0 million (31.3% of Precast net sales) in the second quarter of 2022 and decreased 9.1% to $18.7 million (25.1% of Precast net sales) in the first six months of 2023 compared to $20.6 million (27.0% of Precast net sales) in the first six months of 2022. The decrease was primarily due to increased production costs.

Selling, general, and administrative expense. Selling, general, and administrative expense increased 8.8% to $11.0 million (9.4% of net sales) in the second quarter of 2023 compared to $10.1 million (8.5% of net sales) in the second quarter of 2022 and increased 17.4% to $22.9 million (10.6% of net sales) in the first six months of 2023 compared to $19.5 million (8.6% of net sales) in the first six months of 2022. The increase in the second quarter of 2023 compared to the second quarter of 2022 was primarily due to $0.6 million in higher base compensation and benefits expense, $0.3 million in higher administrative expense, $0.1 million in higher professional fees including ERP implementation fees, $0.1 million in higher advertising expense, and $0.1 million in higher travel expense, partially offset by $0.5 million in lower incentive compensation expense. The increase in the first six months of 2023 compared to the first six months of 2022 was primarily due to $1.5 million in higher base compensation and benefits expense, $0.6 million in higher administrative expense, $0.5 million in higher incentive compensation expense, $0.4 million in higher professional fees including ERP implementation fees, and $0.2 million in higher travel expense.

Income taxes. Income tax expense was $2.7 million in the second quarter of 2023 (an effective income tax rate of 26.5%) compared to $3.4 million in the second quarter of 2022 (an effective income tax rate of 26.1%) and was $3.6 million in the first six months of 2023 (an effective income tax rate of 27.1%) compared to $4.8 million in the first six months of 2022 (an effective income tax rate of 26.4%). The estimated effective income tax rates for the second quarters and first six months of 2023 and 2022 were impacted by non-deductible permanent differences. The estimated effective income tax rate can change significantly depending on the relationship of permanent income tax differences to estimated pre-tax income or loss. 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, the Second Amendment to Credit Agreement dated April 29, 2022, and the Third Amendment to Credit Agreement dated June 29, 2023 (together, 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 six months ended June 30, 2023 and 2022 are presented in our Condensed Consolidated Statements of Cash Flows contained in Part I – Item 1. “Financial Statements” of this 2023 Q2 Form 10‑Q, and are further discussed below.

As of June 30, 2023, our working capital (current assets minus current liabilities) was $184.3 million compared to $187.9 million as of December 31, 2022. Cash and cash equivalents totaled $4.2 million and $3.7 million as of June 30, 2023 and December 31, 2022, 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 June 30, 2023, we had $70.1 million of outstanding revolving loan borrowings, $10.8 million of outstanding current debt, $92.7 million of operating lease liabilities, and $4.8 million of finance lease liabilities. 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.

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $27.5 million in the first six months of 2023 compared to $10.2 million in the first six months of 2022. Net income, adjusted for non-cash items, provided $21.6 million of operating cash flow in the first six months of 2023 compared to $23.2 million of operating cash flow in the first six months of 2022. The net change in working capital provided (used) was $5.9 million of operating cash flow in the first six months of 2023 compared to $(13.0) million of operating cash flow in the first six months of 2022.

Net Cash Used in Investing Activities

Net cash used in investing activities was $11.1 million in the first six months of 2023 compared to $8.4 million in the first six months of 2022. Capital expenditures were $8.4 million in the first six months of 2023 compared to $8.5 million in the first six months of 2022, which was primarily for standard capital replacement. We currently expect capital expenditures in 2023 to be approximately $24 million to $28 million, which includes approximately $4 million of investment in our new reinforced concrete pipe mill, and associated ancillary equipment, and the remainder primarily for standard capital replacement. The $2.7 million payment of the working capital adjustment for the 2021 acquisition of ParkUSA was made in the second quarter of 2023.

Net Cash Used in Financing Activities

Net cash used in financing activities was $15.9 million in the first six months of 2023 compared to $1.2 million in the first six months of 2022. Net repayments on the line of credit were $13.6 million in the first six months of 2023 compared to approximately $0 in the first six months of 2022.

Table of Contents

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 the foreseeable future. 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.

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 2023 Q2 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 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 six months ended June 30, 2023.

Current Debt

The Interim Funding Agreement dated August 2, 2022 with Wells Fargo Equipment Finance, Inc. (“WFEF”), as amended January 23, 2023, March 15, 2023, and July 21, 2023 (together, the “IFA”) provides 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 bore interest at the term Secured Overnight Finance Rate (“SOFR”) plus 1.75% through January 31, 2023. Effective February 1, 2023, the IFA interest rate changed to the SOFR Average plus 1.75%. The IFA requires monthly payments of accrued interest and grants a security interest in the equipment to WFEF. As of June 30, 2023, 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”), with an option for us to increase that amount by $50 million, subject to provisions of the Amended Credit Agreement. The Amended Credit Agreement will expire, and all obligations outstanding will mature, on June 29, 2028. We may prepay outstanding amounts in our discretion without penalty at any time, subject to applicable notice requirements. As of June 30, 2023 under the Amended Credit Agreement, we had $70.1 million of outstanding revolving loan borrowings, $1.1 million of outstanding letters of credit, and additional borrowing capacity of approximately $54 million.

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 June 30, 2023 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.

Table of Contents

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 3.00 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 $35 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 June 30, 2023. 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, “Recent Accounting and Reporting Developments” of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2023 Q2 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 2023 Q2 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, income taxes, allowance for doubtful accounts, 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 six months ended June 30, 2023 as compared to the critical accounting estimates disclosed in our 2022 Form 10‑K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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 June 30, 2023, 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 June 30, 2023. Based on their evaluation, as of June 30, 2023, 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 previously reported material weakness in our internal control over financial reporting.

Previously Reported Material Weakness

As previously reported in Part II, Item 9A. “Controls and Procedures” of our Annual Report on Form 10‑K for the year ended December 31, 2022, 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. The material weakness did not result in any restatements of consolidated financial statements previously reported by us, and there were no changes in previously released financial results.

Remediation

We have taken, and continue to take, steps to remediate the control deficiencies contributing to the material weakness described above. These remediation steps, which are ongoing, have centered primarily on employee training in addition to launching our project to improve the ParkUSA business processes, which will include the assistance of external consultants. We will continue to 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. 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 remediation activities described above, there were no significant changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2023 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, “Commitments and Contingencies” of the Notes to Condensed Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this 2023 Q2 Form 10‑Q.

Item 1A. Risk Factors

In addition to the other information set forth in this 2023 Q2 Form 10‑Q, the factors discussed in Part I – Item 1A. “Risk Factors” in our 2022 Form 10‑K and any subsequently filed quarterly reports on Form 10‑Q could materially affect our business, financial condition, or operating results. The risks described in our 2022 Form 10‑K and subsequent Form 10‑Q’s 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.

Item 5. Other Information

None of the Company’s directors or officers adopted, modified, or terminated a Rule 10b5‑1 trading arrangement or a non-Rule 10b5‑1 trading arrangement during the quarter ended June 30, 2023, as such terms are defined under Item 408(a) of Regulation S‑K.
