Introduction
Knife River is a leading aggregates-based construction materials and contracting services provider in the United States. The Company's aggregate reserves provide the foundation for its vertically integrated business strategy, with approximately 40 percent of its aggregates in 2023 being used internally to support value-added downstream products (ready-mix concrete and asphalt) and contracting services (heavy-civil construction, asphalt paving, concrete construction, site development and grading services). The Company provides construction materials and contracting services for both public and private customers and is focused on being the provider of choice in mid-size, high-growth markets. Knife River is committed to its plan for continued growth and to delivering for its stakeholders — customers, communities, employees and stockholders — by executing on its four core values: people, safety, quality and the environment.
The Company supplies construction materials to customers in 14 states and also provides related contracting services. It has broad access to high-quality aggregates in most of its markets, which forms the foundation of its vertically integrated business model. Knife River shares resources, including plants, equipment and people, across its various locations to maximize efficiency, and it transports its products by truck, rail and barge to complete the vertical value chain, depending on the particular market. The Company's strategically located aggregate sites, ready-mix plants and asphalt plants, along with its fleet of ready-mix and dump trucks, enables Knife River to better serve its customers. The Company believes its vertically integrated business model is a strong competitive advantage that provides scale, efficiency and operational excellence for the benefit of customers, stockholders and the broader communities that it serves.
The Company is organized into six operating regions: Pacific, Northwest, Mountain, North Central, South and Energy Services. These regions are used to determine the Company's reportable segments, which are based on the Company's method of internal reporting and are aligned by key geographic regions due to the production of construction materials and related contracting services following the seasonal nature of the construction industry. Knife River's reportable segments are: Pacific, Northwest, Mountain and North Central, with South and Energy Services included in the All Other category with its corporate services. The internal reporting of these segments is defined based on the reporting and review process used by the Company's chief executive and chief operating officers. For more information on the Company's business segments, see Note 15 of the Notes to Consolidated Financial Statements.
On May 31, 2023, the Separation of Knife River from MDU Resources was completed as a tax-free spin-off for U.S. federal income tax purposes. As a result of the Separation, MDU Resources distributed shares representing approximately 90 percent of Knife River's outstanding common stock to holders of record of MDU Resources' common stock as of the close of business on May 22, 2023. Following the Distribution, Knife River became an independent, publicly traded company.

Note 1 - Background
On August 4, 2022, MDU Resources announced that its board of directors approved a plan to pursue the Separation of Knife River from MDU Resources. On May 31, 2023, the Separation was completed by a pro rata distribution of shares representing approximately 90 percent of Knife River's outstanding common stock to MDU Resources' stockholders. MDU Resources' stockholders received one share of Knife River common stock for every four shares of MDU Resources common stock held as of the close of business on May 22, 2023. MDU Resources retained approximately 10 percent of Knife River's common stock. The Distribution was tax-free to its stockholders for U. S. federal income tax purposes. At the time of the Separation, the net parent investment in Knife River held by Centennial was settled between the companies. As a result of the Separation, Knife River is now an independent public company trading on the New York Stock Exchange under the symbol "KNF." More information on the Separation and Distribution, as well as the Company's historical results, can be found within the Company's Registration Statement on Form 10.
Note 2 - Basis of presentation
The accompanying consolidated interim financial statements were prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with the Company's Registration Statement on Form 10. The information is unaudited but includes adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature.
On May 31, 2023, the Company became a stand-alone publicly traded company. Prior to the Separation on May 31, 2023, Knife River operated as a wholly owned subsidiary of Centennial and an indirect, wholly owned subsidiary of MDU Resources and not as a stand-alone company. These consolidated financial statements and footnotes reflect the historical financial position, results of operations and cash flows of the Company as historically managed within MDU Resources for the periods prior to the completion of the Separation and reflect the financial position, results of operations and cash flows as a stand-alone company for the period after the completion of the Separation. The historical consolidated financial statements and footnotes were prepared on a “carve-out” basis in connection with the Separation and were derived from the consolidated financial statements of MDU Resources as if the Company operated on a stand-alone basis during the periods presented, and were prepared utilizing the legal entity approach in conformity with GAAP. The results for the three and nine months ended September 30, 2022, vary from the previously reported MDU Resources' construction materials and contracting services segment due to an adjustment to a cost allocation for interim periods to conform with the Company's current year accounting. This adjustment does not impact the historical annual financial statements included in the Company's Registration Statement on Form 10. This adjustment increased cost of revenue for the three months ended September 30, 2022, by $4.4 million ($3.4 million after tax) and decreased cost of revenue for the nine months ended September 30, 2022, by $1.6 million ($1.2 million after tax). The adjustment is not considered material for the three or nine months ended September 30, 2022.
The Company utilized allocations and carve-out methodologies to prepare its historical consolidated financial statements and footnotes. The consolidated financial statements and footnotes herein may not be indicative of the Company's future performance or actual expenses that would have been incurred as a stand-alone company for the periods presented.
All revenues and costs, as well as assets and liabilities, directly associated with the business activity of the Company are included in the consolidated financial statements. In the periods prior to the Separation, the consolidated financial statements include expense allocations for certain functions provided by MDU Resources and Centennial, including, but not limited to certain general corporate expenses related to senior management, legal, human resources, finance and accounting, treasury, information technology, communications, procurement, tax, insurance and other shared services. These general corporate expenses are included in the Consolidated Statements of Operations within selling, general and administrative expenses and other income (expense). There were no amounts allocated to Knife River for the three months ended September 30, 2023, and $8.7 million was allocated for the nine months ended September 30, 2023. For the three and nine months ended September 30, 2022, there was $3.8 million and $13.4 million, respectively, allocated to Knife River. These expenses have been allocated to the Company on the basis of direct usage when identifiable, with the remainder principally allocated on the basis of percent of total capital invested or other allocation methodologies that are considered to be a reasonable reflection of the utilization of the services provided to the benefits received, including the following: number of employees paid and stated as cost per check; number of employees served; weighted factor of travel, managed units, national account spending, equipment and fleet acquisitions; purchase order dollars spent and purchase order line count; number of payments, vouchers or unclaimed property reports; labor hours; time tracked; and projected workload.

Prior to the Separation, Knife River historically participated in Centennial’s centralized cash management program, including its overall financing arrangements. This arrangement is not reflective of the manner in which the Company would have been able to finance its operations had it been independent from MDU Resources for the period prior to the completion of the Separation. Knife River had related-party note agreements in place with Centennial for the financing of its capital needs, which are reflected as related-party notes payable on the Consolidated Balance Sheets as of December 31, 2022. The related-party notes payable to Centennial at May 30, 2023, was $889.7 million. As part of the Separation, Centennial made an equity contribution to the Company to release the Company of its obligation related to the outstanding notes payable. Also as part of the Separation, the Company entered into debt agreements and subsequently paid a dividend of $825.0 million from the debt proceeds to Centennial, which Centennial used to repay a portion of the Company's outstanding indebtedness. These transactions resulted in the Company receiving a net equity contribution of $64.7 million and is reflected as "Net transfers from Centennial and MDU Resources including separation adjustments" in the Consolidated Statement of Equity. Interest expense in the Consolidated Statements of Operations includes the allocation of interest on borrowing and funding associated with the related-party note agreements for periods prior to the Separation.
Prior to the Separation, income tax expense and tax balances in the consolidated financial statements were calculated on a separate tax return basis. The separate tax return method applies the accounting guidance for income taxes to the standalone financial statements as if the Company were a separate taxpayer and a standalone enterprise. Management believes the assumptions supporting the allocation and presentation of income taxes on a separate return basis are reasonable. As a stand-alone entity, the Company will file tax returns on its own behalf, and tax balances and effective income tax rate may differ from the amounts reported in the historical periods.
Management has also evaluated the impact of events occurring after September 30, 2023, up to the date of issuance of these consolidated interim financial statements on November 6, 2023, that would require recognition or disclosure in the Consolidated Financial Statements.
Principles of consolidation
For the pre-Separation periods, the accompanying financial statements of the Company were derived from the consolidated financial statements and accounting records of MDU Resources as if the Company and its wholly owned subsidiaries operated on a stand-alone basis during the periods presented. The consolidated financial statements were prepared in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions between the businesses comprising the Company have been eliminated in the accompanying consolidated financial statements. Related-party transactions between the Company and MDU Resources or Centennial for general operating activities and intercompany debt have been included in the consolidated financial statements for the pre-Separation periods. These related-party transactions were settled in cash and are reflected in the pre-Separation Consolidated Balance Sheets as “Due from related-party” or “Due to related-party” with the aggregate net effect reflected in the Consolidated Statements of Cash Flows within operating activities and “Related-party notes payable” with the aggregate net effect reflected in the Consolidated Statements of Cash Flows within financing activities.
The aggregate net effect of related-party transactions not settled in cash as part of the Separation have been reflected in the pre-Separation Consolidated Balance Sheet within “Other paid-in capital”. See Note 18 for additional information on related-party transactions.
Use of estimates
The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; aggregate reserves; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; expected credit losses; environmental and other loss contingencies; costs on contracting services contracts; actuarially determined benefit costs; asset retirement obligations; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. These estimates are based on management’s best knowledge of current events, historical experience, actions that the Company may undertake in the future and on various other assumptions that are believed to be reasonable under the circumstances. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.
New accounting standards
There have been no recent accounting standards that are expected to materially affect the Company.
Cash, cash equivalents and restricted cash
The Company considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash and cash equivalents. At September 30, 2023, the $116.2 million of cash, cash equivalents and restricted cash on the Consolidated Statements of Cash Flows is comprised of $84.0 million of cash and cash equivalents and $32.2 million of restricted cash. At September 30, 2022, the Company did not have any restricted cash. Restricted cash represents deposits held by Knife
12

River's captive insurance company that is required by state insurance regulations to remain in the captive insurance company as cash.
Seasonality of operations
Some of the Company's operations are seasonal and revenues from, and certain expenses for, such operations may fluctuate significantly among quarterly periods, with lower activity in the winter months and higher activity in the summer months. Accordingly, the interim results for particular segments, and for the Company as a whole, may not be indicative of results for the full fiscal year or other future periods.
Note 3 - Receivables and allowance for expected credit losses
Receivables consist primarily of trade and contract receivables for the sale of goods and services net of expected credit losses. A majority of the Company's receivables are due in 30 days or less. The total balance of receivables past due 90 days or more was $14.4 million and $11.2 million at September 30, 2023 and December 31, 2022, respectively. Receivables were as follows:

Less expected credit loss6,1955,477
Receivables, net$491,866$210,157
The Company's expected credit losses are determined through a review using historical credit loss experience; changes in asset specific characteristics; current conditions; and reasonable and supportable future forecasts, among other specific account data, and is performed at least quarterly. The Company develops and documents its methodology to determine its allowance for expected credit losses. Risk characteristics used by the Company may include customer mix, knowledge of customers and general economic conditions of the various local economies, among others. Specific account balances are written off when management determines the amounts to be uncollectible. Management has reviewed the balance reserved through the allowance for expected credit losses and believes it is reasonable.

Inventories are valued at the lower of cost or net realizable value using the average cost method. Inventories include production costs incurred as part of the Company's aggregate mining activities. These inventoriable production costs include all mining and processing costs associated with the production of aggregates. Stripping costs incurred during the production phase, which represent costs of removing overburden and waste materials to access mineral deposits, are a component of inventoriable production costs.
Note 5 - Earnings per share
The calculation for basic and diluted earnings per share for any period presented prior to the Separation are based on the number of shares outstanding on May 31, 2023, the Separation and Distribution date. For periods prior to the Separation, it is assumed that there are no dilutive equity instruments as there were no Knife River stock-based awards outstanding at the time.
Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the applicable period. Diluted earnings per share is computed by dividing net income by the total of the weighted average number of shares of common stock outstanding during the applicable period, plus the effect of non-vested restricted stock units. Weighted average common shares outstanding is comprised of issued shares of 56,997,350 less shares held in treasury of 431,136, as described in Note 6. Basic and diluted earnings per share are calculated as follows, based on a reconciliation of the weighted-average common shares outstanding on a basic and diluted basis:

Note 6 - Equity
On May 31, 2023, the Company issued 56,997,350 shares of common stock with a par value of $0.01 in connection with the Separation.
The Company historically held 538,921 shares of MDU Resources common stock through one of its subsidiaries. The historical shares are presented as MDU Resources' stock held by subsidiary on the Consolidated Statement of Equity. In connection with the Separation, Knife River entered into an agreement with MDU Resources to transfer the stock of MDU Resources held by its subsidiary to MDU Resources in exchange for 431,136 shares of Knife River common stock. The number of shares transferred to Knife River was based on the value of the stock at the time of the Separation. The historical MDU Resources common stock held by subsidiary at cost of $3.6 million at September 30, 2023, on the Consolidated Balance Sheets reflects the value of the MDU Resources common stock at the time it was granted to Knife River's subsidiary and will remain at the historical value since the exchange was between related parties. The 431,136 shares of Knife River common stock are presented as Treasury stock held at cost in the Consolidated Balance Sheet and reduce the number of common stock shares outstanding.
Stock-based compensation
Prior to the Separation, key employees of the Company participated in various stock-based compensation plans authorized and managed by MDU Resources. All awards granted under the plans were based on MDU Resources' common shares, however, Knife River recognized the expense for its participants in its financial statements.
At the time of the Separation, each outstanding MDU Resources time-vested restricted stock unit and performance share award held by a Knife River employee was converted into Knife River time-vested restricted stock units. The converted awards will continue to vest over the original vesting period, which is generally three years from the grant date. All performance share awards that were converted at the time of the Separation were first adjusted using a combined performance factor based on MDU Resources' actual performance as of December 31, 2022. The number of restricted stock units was determined by taking the closing per share price of MDU Resources on May 31, 2023, and dividing by the closing per share price of Knife River on June 1, 2023. The ratio used to convert the MDU Resources' share-based awards was designed to preserve the aggregate intrinsic value of the award immediately after the Separation when compared to the aggregate intrinsic value of the award immediately prior to the Separation. The existing unvested stock-based awards issued through MDU Resources' stock-based compensation plans were modified in connection with the Separation to maintain an equivalent value immediately before and after Separation. The impact of this modification will be recorded over the remaining vesting periods and was not material to the Company's stock-based compensation expense for the three or nine months ended September 30, 2023.

Note 8 - Revenue from contracts with customers
Revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer. Revenue includes revenue from the sales of construction materials and contracting services. Revenue is measured based on consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes. Revenue for construction materials is recognized at a point in time when delivery of the products has taken place. Contracting revenue is recognized over time using an input method based on the cost-to-cost measure of progress on a project.
Disaggregation
In the following tables, revenue is disaggregated by category for each segment and includes sales of materials to both third parties and internal customers. Due to consolidation requirements, the internal sales revenues must be eliminated against the construction materials product used in downstream materials and contracting services to arrive at the external operating revenues. The Company believes this level of disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. For more information on the Company’s reportable segments, see Note 15.

Note 9 - Uncompleted contracts
The timing of revenue recognition may differ from the timing of invoicing to customers. The timing of invoicing to customers does not necessarily correlate with the timing of revenues being recognized under the cost-to-cost method of accounting. Contracts from contracting services are billed as work progresses in accordance with agreed upon contractual terms. Generally, billing to the customer occurs contemporaneous to revenue recognition. A variance in timing of the billings may result in a contract asset or a contract liability. A contract asset occurs when revenues are recognized under the cost-to-cost measure of progress, which exceeds amounts billed on uncompleted contracts. Such amounts will be billed as standard contract terms allow, usually based on various measures of performance or achievement. A contract liability occurs when there are billings in excess of revenues recognized under the cost-to-cost measure of progress on uncompleted contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation.
The changes in contract assets and liabilities were as follows:

The Company recognized $3.4 million and $35.1 million in revenue for the three and nine months ended September 30, 2023, respectively, which was previously included in contract liabilities at December 31, 2022. The Company recognized $3.0 million and $29.2 million in revenue for the three and nine months ended September 30, 2022, respectively, which was previously included in contract liabilities at December 31, 2021.
The Company recognized a net increase in revenues of $12.1 million and $10.6 million for the three and nine months ended September 30, 2023, respectively, from performance obligations satisfied in prior periods. The Company recognized a net increase in revenues of $4.9 million and $10.4 million for the three and nine months ended September 30, 2022, respectively, from performance obligations satisfied in prior periods.
Remaining performance obligations
The remaining performance obligations, also referred to as backlog, include unrecognized revenues that the Company reasonably expects to be realized. These unrecognized revenues can include: projects that have a written award, a letter of intent, a notice to proceed, an agreed upon work order to perform work on mutually accepted terms and conditions and change orders or claims to the extent management believes additional contract revenues will be earned and are deemed probable of collection. The majority of the Company's contracts for contracting services have an original duration of less than one year.
At September 30, 2023, the Company's remaining performance obligations were $732.2 million. The Company expects to recognize the following revenue amounts in future periods related to these remaining performance obligations: $677.7 million within the next 12 months or less; $38.5 million within the next 13 to 24 months; and $16.0 million in 25 months or more.

Note 11 - Fair value measurements
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The fair value ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach.
The Company measures its investments in certain fixed-income and equity securities at fair value with changes in fair value recognized in income. The Company anticipates using these investments, which consist of insurance contracts, to satisfy its obligations under its unfunded, nonqualified defined benefit and defined contribution plans for the Company's executive officers and certain key management employees, and invests in these fixed-income and equity securities for the purpose of earning investment returns and capital appreciation. These investments, which totaled $23.5 million and $20.1 million at September 30, 2023 and December 31, 2022, respectively, are classified as investments on the Consolidated Balance Sheets. The net unrealized loss on these investments was $597,000 for the three months ended September 30, 2023 and the net unrealized gain on these investments was $685,000 for the nine months ended September 30, 2023. The net unrealized loss on these investments was $541,000 and $3.2 million for the three and nine months ended September 30, 2022, respectively. The change in fair value, which is considered part of the cost of the plan, is classified in other income on the Consolidated Statements of Operations.
As part of the Separation, the Company retired certain insurance contracts used to satisfy its obligations under its unfunded, nonqualified defined contribution plan for the Company's executive officers and certain key management employees. The proceeds of the retired contracts totaled $4.8 million, which were used to purchase life insurance policies and re-invested in fixed-income and equity securities in the third quarter of 2023.

The Company’s Level 2 money market funds are valued at the net asset value of shares held at the end of the period, based on published market quotations on active markets, or using other known sources including pricing from outside sources. The estimated fair value of the Company’s Level 2 insurance contracts are based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.
Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value.
The Company applies the provisions of the fair value measurement standard to its nonrecurring, non-financial measurements, including long-lived asset impairments. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. The Company reviews the carrying value of its long-lived assets, excluding goodwill, whenever events or changes in circumstances indicate that such carrying amounts may not be recoverable.
The Company's long-term debt is not measured at fair value on the Consolidated Balance Sheets and the fair value is being provided for disclosure purposes only. The fair value was categorized as Level 2 in the fair value hierarchy and was based on discounted cash flows using current market interest rates.

Note 12 - Debt
Certain debt instruments of the Company contain restrictive covenants and cross-default provisions. In order to borrow under the debt agreements, the Company must be in compliance with the applicable covenants and certain other conditions, all of which management believes the Company, as applicable, was in compliance with at September 30, 2023. In the event the Company does not comply with the applicable covenants and other conditions, alternative sources of funding may need to be pursued.
On April 25, 2023, the Company issued $425.0 million of 7.75 percent senior notes due May 1, 2031, pursuant to an indenture.
On May 31, 2023, the Company entered into a senior secured credit agreement consisting of a $275.0 million term loan and a $350.0 million revolving credit facility. As of September 30, 2023, the Company had no outstanding borrowings against the revolving credit facility. Each debt facility has a SOFR-based interest rate and a maturity date of May 31, 2028. The term loan has a mandatory annual amortization of 2.50 percent for years one and two, 5.00 percent for years three and four, and 7.50 percent in the fifth year. The agreement contains customary covenants and provisions, including a covenant of Knife River not to permit, at any time, the ratio of total debt to trailing twelve month EBITDA to be greater than 4.75 to 1.00. The agreement also contains an interest coverage ratio covenant stating that Knife River’s trailing twelve month EBITDA to interest expense is to be no less than 2.25 to 1.00. The covenants also include restrictions on the sale of certain assets, loans and investments.
Knife River's wholly owned subsidiary companies, subject to certain exclusions and exceptions, are named as subsidiary guarantors of the senior notes and the senior secured credit agreement. In addition, Knife River has pledged substantially all of its assets as collateral, subject to certain exclusions and exceptions, for the senior secured credit agreement.

Note 13 - Income taxes
Post-Separation, the income tax provisions are calculated based on Knife River's operating footprint, as well as tax return elections and assertions. Current income tax liabilities including amounts for unrecognized tax benefits related to the Company's activities included in MDU Resources' income tax returns were deemed to be immediately settled with MDU Resources' final settlement allocation process as dictated by the MDU Resources' Tax Sharing Agreement.
Prior to the Separation, income tax expense and tax balances in the consolidated financial statements were calculated on a separate tax return basis. The separate tax return method applies the accounting guidance for income taxes to the stand-alone financial statements as if the Company were a separate taxpayer and a stand-alone enterprise. Management believes the assumptions supporting the allocation and presentation of income taxes on a separate return basis are reasonable. As a stand-alone entity, the Company will file tax returns on its own behalf, and tax balances and effective income tax rate may differ from the amounts reported in the historical periods.
Income tax expense is based on reported income before income taxes. Deferred income taxes reflect the tax effect of temporary differences between asset and liability amounts that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. These deferred taxes are measured by applying currently enacted tax laws.
21

Valuation allowances are recognized to reduce deferred tax assets to the amount that will more likely than not be realized. In assessing the need for a valuation allowance, management considers all available evidence for each jurisdiction including past operating results, estimates of future taxable income and the feasibility of ongoing tax planning strategies and actions. When there is a change in determination as to the amount of deferred tax assets that can be realized, the valuation allowance is adjusted with a corresponding impact to provision for income taxes in the period in which such determination is made.
The Company's cash tax payments for the year may vary significantly from prior years as a result of the timing of the Separation and the seasonality of the Company's business.
Other Tax Matters
Tax Matters Agreement In connection with the Separation, the Company entered into a tax matters agreement with MDU Resources. The tax matters agreement governs the respective rights, responsibilities, and obligations between the Company and MDU Resources after the Separation with respect to tax liabilities and benefits, tax attributes, tax returns, tax contests and other tax sharing regarding U.S. federal, state and local income taxes, other tax matters and related tax returns.
Tax Refunds and Attributes The tax matters agreement provides for the allocation of certain pre-closing tax attributes between the Company and MDU Resources. Tax attributes will be allocated in accordance with the principles set forth in the MDU Resources' Tax Sharing Agreement, then existing, unless otherwise required by law. Under the tax matters agreement, the Company will be entitled to refunds for taxes for which the Company is responsible.

Note 15 - Business segment data
The Company focuses on the vertical integration of its products and services by offering customers a single source for construction materials and related contracting services. The Company operates in 14 states across the United States. Its operating segments include: Pacific, Northwest, Mountain, North Central, South and Energy Services. The operating segments are organized by geographic region in the United States due to the cyclical nature of the construction work performed. The Company’s reportable segments are those that are based on the Company’s method of internal reporting and management of the business and are Pacific, Northwest, Mountain and North Central. The South and Energy Services operating segments do not meet the criteria to be reportable segments and, as such, are combined with its corporate services in All Other. Each segment is led by a segment president that reports to the Company’s chief operating officer. The chief operating officer works directly with the chief executive officer, the chief operating decision maker, to evaluate the performance of the segments using EBITDA and the allocation of resources.
All of the reportable segments mine, process and sell construction aggregates (crushed stone and sand and gravel); produce and sell asphalt; and produce and sell ready-mix concrete, as well as in some segments the sale of merchandise and other building materials and related services, as well as vertically integrating their contracting services to support the aggregate-based product lines including heavy-civil construction, asphalt and concrete paving, and site development and grading, and in some segments the manufacturing of prestressed concrete products. The Pacific segment and All Other also produce and sell liquid asphalt products and the Pacific segment sells cement. Although not common to all locations, within All Other is the sale of merchandise and other building materials and related services.

Note 16 - Employee benefit plans
The Company has noncontributory qualified defined benefit pension plans and other postretirement benefit plans for certain eligible employees. Prior to the Separation, Knife River was a participant in the MDU Resources postretirement benefit plan. The Company historically treated its share of the postretirement obligation under that plan as a single employer plan in accordance with ASC 715 - Compensation - Retirement Benefits and recorded the funded status and net periodic benefit cost associated with Knife River employees at Knife River. In connection with the Separation, effective June 1, 2023, Knife River established a new, stand-alone postretirement plan comparable to that of MDU Resources and transferred its obligations of $1.5 million for current participants (inclusive of employees that transferred to the Company from MDU Resources) to that plan. The Company's pension benefit plans were stand-alone for Knife River prior to the Separation.

Note 17 - Contingencies
The Company is party to claims and lawsuits arising out of its business and that of its consolidated subsidiaries, which may include, but are not limited to, matters involving property damage, personal injury, and environmental, contractual and statutory obligations. The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories.
At September 30, 2023 and December 31, 2022, the Company accrued contingent liabilities as a result of litigation, which have not been discounted, of $645,000 and $1.0 million, respectively. At December 31, 2022, the Company also recorded corresponding insurance receivables of $325,000 related to the accrued liabilities. Most of these claims and lawsuits are covered by insurance, thus the Company's exposure is typically limited to its deductible amount. The Company will continue to monitor each matter and adjust accruals as might be warranted based on new information and further developments. Management believes that the outcomes with respect to probable and reasonably possible losses in excess of the amounts accrued, net of insurance
24

recoveries, while uncertain, either cannot be estimated or will not have a material effect upon the Company's financial position, results of operations or cash flows. Unless otherwise required by GAAP, legal costs are expensed as they are incurred.
Environmental matters
The Company is a party to claims for the cleanup of a superfund site in Portland, Oregon. There were no material changes to the Company's environmental matters that were previously reported in the audited financial statements and notes included in the Company's Registration Statement on Form 10.
Guarantees
Certain subsidiaries of the Company have outstanding obligations to third parties where the Company has guaranteed their performance. These guarantees are related to contracts for contracting services and certain other guarantees. At September 30, 2023, the fixed maximum amounts guaranteed under these agreements aggregated to $11.5 million, all of which have no scheduled maturity date. Certain of the guarantees also have no fixed maximum amounts specified. There were no amounts outstanding under the previously mentioned guarantees at September 30, 2023.
Certain subsidiaries of the Company have outstanding letters of credit to third parties related to insurance policies, cement purchases and other agreements. At September 30, 2023, the fixed maximum amounts guaranteed under these letters of credit aggregated $4.8 million. At September 30, 2023, the amounts of scheduled expiration of the maximum amounts guaranteed under these letters of credit aggregate to $4.0 million in 2023 and $771,000 in 2024. There were no amounts outstanding under the previously mentioned letters of credit at September 30, 2023.
In the normal course of business, the Company has surety bonds related to contracts for contracting services, reclamation obligations and insurance policies of its subsidiaries. In the event a subsidiary of the Company does not fulfill a bonded obligation, the Company would be responsible to the surety bond company for completion of the bonded contract or obligation. A large portion of the surety bonds is expected to expire within the next 12 months; however, the Company will likely continue to enter into surety bonds for its subsidiaries in the future. At September 30, 2023, approximately $619.2 million of surety bonds were outstanding, which were not reflected on the Consolidated Balance Sheet.
Note 18 - Related-party transactions
Transition services agreements
As part of the Separation, MDU Resources is providing transition services to the Company and the Company is providing transition services to MDU Resources in accordance with the Transition Services Agreement entered into on May 30, 2023. For the three and nine months ended September 30, 2023, the Company paid $1.3 million and $1.9 million, respectively, related to these activities, which were reflected in selling, general and administrative expenses on the Consolidated Statements of Operations. For the three and nine months ended September 30, 2023, the Company received $407,000 and $684,000, respectively, related to these activities, which were reflected in other income (expense) on the Consolidated Statements of Operations. The majority of the transition services are expected to be completed over a period of one year, but no longer than two years after the Separation.
Related-party notes payable
The related-party notes payable to Centennial at May 30, 2023, was $889.7 million. As part of the Separation, Centennial made an equity contribution to the Company to release the Company of its obligation related to the outstanding notes payable. Also as part of the Separation, the Company issued $425.0 million of 7.75 percent senior notes due May 1, 2031, a credit agreement consisting of a $275.0 million term loan and a $350.0 million revolving credit facility, of which $190.0 million was drawn down at the time of the Separation. On May 31, 2023, the Company paid a dividend of $825.0 million from these proceeds to Centennial, which Centennial used to repay a portion of the Company's outstanding indebtedness. These transactions resulted in the Company receiving a net equity contribution of $64.7 million and is reflected as "Net transfers from Centennial and MDU Resources including separation adjustments" in the Consolidated Statement of Equity. Refer to Note 12 for additional information on the debt facilities entered into in connection with the Separation.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
Knife River is a people-first construction materials and contracting services company. The Company provides construction materials and contracting services to build safe roads, bridges and airport runways that connect people with where they want to go and with the supplies they need. Knife River also champions a positive workplace culture by focusing on safety, training, inclusion, compensation and work-life balance.
Knife River is one of the leading providers of crushed stone and sand and gravel in the United States and operates through six regions: Pacific, Northwest, Mountain, North Central, South and Energy Services, with operations across 14 states. These regions are used to determine the Company's reportable segments and are based on the Company's method of internal reporting and management of the business. The Company's reportable segments are: Pacific, Northwest, Mountain, and North Central, with South and Energy Services included in All Other with its corporate services. The segments primarily provide aggregates, asphalt and ready-mix concrete, as well as related contracting services such as heavy-civil construction, asphalt paving, concrete delivery and paving, site development and grading.
As a leading aggregates-based construction materials and contracting services provider in the United States, the Company's 1.1 billion tons of aggregate reserves provide the foundation for a vertically integrated business strategy, with approximately 40 percent of its aggregates in 2023 being used internally to support value-added downstream products (ready-mix concrete and asphalt) and contracting services (heavy-civil construction, asphalt paving, concrete construction, site development and grading services, and in some segments the manufacturing of prestressed concrete products). Its aggregate sites and associated asphalt and ready-mix plants are primarily in strategic locations near mid-sized, high-growth markets, providing Knife River with a transportation advantage for its materials that supports competitive pricing and increased margins. Knife River provides its products and services to both public and private markets, with public markets tending to be more stable across economic cycles, which helps offset the cyclical nature of the private markets.
The Company provides various products and services and operates a variety of facility types, including aggregate quarries and mines, ready-mix concrete plants, asphalt plants and distribution facilities. The Company operates in the following states:
Pacific: Alaska, California and Hawaii
Northwest: Oregon and Washington
Mountain: Idaho, Montana and Wyoming
North Central: Iowa, Minnesota, North Dakota and South Dakota
All Other: Iowa, Nebraska, North Dakota, South Dakota, Texas and Wyoming

The Separation
On August 4, 2022, MDU Resources announced that its board of directors approved a plan to pursue the Separation of Knife River from MDU Resources. On May 31, 2023, the Separation was completed by a pro rata distribution of shares representing approximately 90 percent of Knife River's outstanding common stock to MDU Resources' stockholders. MDU Resources' stockholders received one share of Knife River common stock for every four shares of MDU Resources common stock held as of the close of business on May 22, 2023. MDU Resources retained approximately 10 percent of Knife River's common stock. The Distribution was tax-free to its stockholders for U. S. federal income tax purposes. At the time of the Separation, the net parent investment in Knife River held by Centennial was settled between the companies. As a result of the Separation, Knife River is now an independent public company trading on the New York Stock Exchange under the symbol "KNF." More information on the Separation and Distribution, as well as the Company's historical results, can be found within the Company's Registration Statement on Form 10.
Forward-Looking Statements

Basis of Presentation
Knife River historically operated as a wholly owned subsidiary of Centennial and an indirect, wholly owned subsidiary of MDU Resources and not as a stand-alone company until the Separation from MDU Resources was completed. The accompanying historical consolidated financial statements and footnotes, which were prepared on a “carve-out” basis in connection with the Separation, were derived from the consolidated financial statements of MDU Resources as if the Company operated on a stand-alone basis during the historical periods presented, and were prepared utilizing the legal entity approach in conformity with GAAP. For additional information related to the basis of presentation, see Note 2.
Prior to the Separation, Knife River historically participated in Centennial’s centralized cash management program, including its overall financing arrangements. Knife River had related-party note agreements in place with Centennial for the financing of its capital needs, which are reflected as related-party notes payable on the Consolidated Balance Sheet at December 31, 2022. Interest expense in the Consolidated Statements of Operations reflects the allocation of interest on borrowing and funding associated with the related-party note agreements. Upon the completion of the Separation, Knife River implemented its own financing agreements with lenders. For additional information on the Company's current debt financing, see Note 12.
All intercompany balances and transactions between the businesses comprising Knife River have been eliminated in the accompanying consolidated financial statements.
Market Conditions and Outlook
Knife River’s markets remain resilient and construction activity remains generally strong despite general and economic challenges, such as transportation disruptions, supply-chain constraints, inflation and higher interest rates. With approximately 80 percent of its contracting revenue from public-sector projects, Knife River has been able to balance the cyclical nature of its private-sector customers. While Knife River experienced inflationary pressures in the past year, price increases have generally outpaced the increased costs. For more information on factors that may negatively impact Knife River's business, see the section entitled "Risk Factors" in the Company's Registration Statement on Form 10.
Backlog. Knife River’s contracting services backlog was as follows:
September 30, 2023September 30, 2022
(In millions)
Pacific$69.8 $79.1 
Northwest227.4 150.6 
Mountain251.1 310.9 
North Central109.3 181.1 
All Other74.6 82.0 
$732.2 $803.7 
27

Expected margins on backlog at September 30, 2023, were greater than the expected margins on backlog at September 30, 2022. Approximately 83 percent of the Company's backlog at September 30, 2023, relates to publicly funded projects, including street and highway construction projects, which are driven primarily by public works projects for state departments of transportation. Period-over-period increases or decreases cannot be used as an indicator of future revenues, net income or EBITDA. While the Company believes the current backlog of work remains firm, prolonged delays in the receipts of critical supplies and materials or continued increases to pricing, among other things, could result in customers seeking to delay or terminate existing or pending agreements and could reduce expected margins. See the section entitled “Risk Factors” in the Company's Registration Statement on Form 10 for a list of factors that can cause revenues to be realized in periods and at levels that are different from originally projected.
Public Funding. Funding for public projects is dependent on federal and state funding, such as appropriations to the Federal Highway Administration. The American Rescue Plan Act enacted in the first quarter of 2021 provides $1.9 trillion in COVID-19 relief funding for states, schools and local governments. States are moving forward with allocating these funds based on federal criteria and state needs, and in some cases, funding of infrastructure projects could positively impact Knife River. Additionally, the IIJA was enacted in the fourth quarter of 2021 and is providing long-term opportunities by designating $131 billion in funding across Knife River’s footprint. IIJA funding has been making its way to the 14 states where Knife River operates, with a total of nearly $80 billion having been allocated to specific projects in those states as of August 2023. In addition to federal funding, 12 out of the 14 states in which Knife River operates have implemented new funding mechanisms for public projects, including projects related to highways, airports and other public infrastructure. Knife River continues to monitor the implementation and impact of these legislative items.
Profitability. Knife River’s management continually monitors its margins and has been proactive in applying strategies to address the inflationary impacts seen across the United States. In 2023, the Company began implementing EDGE to improve margins and to execute on other strategic initiatives aimed at generating long-term profitable growth. The EDGE acronym stands for EBITDA Margin Improvement, Discipline, Growth and Excellence. As part of this strategy, Knife River has increased its product pricing over the past year and is targeting higher-margin bidding opportunities. In addition, the Company has established dedicated teams that assist with implementing cost-savings initiatives to further enhance its gross margin.
Knife River operates in geographically diverse and competitive markets, and strives to maximize efficiencies, including transportation costs and economies of scale, to maintain strong margins. Its margins can experience negative pressure from competition, as well as impacts from the volatility in the cost of raw materials, such as diesel fuel, gasoline, natural gas, liquid asphalt, cement and steel, with fuel and liquid asphalt costs often having the most significant impact on results. Many of these raw materials are subject to factors that are beyond the control of the Company, including global economic and political events and new and changing governmental regulations. The energy services business is particularly susceptible to volatility in liquid asphalt costs, which can impact both cost of sales and revenues, for which the Company cannot reliably predict future pricing. Such volatility and inflationary pressures may have an impact on the Company’s margins, including fixed-price contracting services contracts that are particularly vulnerable to the volatility of energy and material prices. The Company mitigates its exposure to these fluctuations by entering into various purchase commitments, as well as by generally including terms in the Company's contracting services agreements that provide for price adjustments related to variations in raw materials costs.
Knife River's operations can also be significantly impacted by both favorable and unfavorable weather conditions. Unseasonably wet and/or cold weather in the states where it operates can delay the start or cause an early end to the construction season or cause temporary delays on specific projects, while unseasonably dry or warm weather in the states where it operates can allow for an early start to construction season or allow for early completions on specific projects. Either of these conditions can impact both its construction materials sales and contracting services revenues. In early 2023, the Company saw record levels of precipitation in the western part of the United States, which caused work to be delayed until later in the year. During the third quarter, the Company largely caught up on this work, as reflected in the Pacific segment results of operations. Other variables that can impact Knife River’s margins include the timing of project starts or completions, and declines or delays in new and existing projects due to the cyclical nature of the construction industry. Accordingly, operating results in any particular period may not be indicative of the results that can be expected for any other period.
Workforce. As a people-first company, Knife River continually takes steps to address the challenge of recruitment and retention of employees. To help attract new workers to the construction industry and enhance the skills of its current employees, Knife River operates a state-of-the-art training facility. The Knife River Training Center offers hands-on training for construction-related careers, including heavy-equipment operators and truck drivers in addition to safety and leadership training. One of the most popular courses is CDL training, which is helping to address some of the recent labor shortages and trends. Through September 30, 2023, training center staff have provided 18 entry-level driver's training sessions for 141 CDL students since opening in 2022, including seven classes for 55 students in 2023. Students graduating from the Knife River CDL program have had a 98 percent success rate earning their CDLs.
Today’s labor market includes an aging workforce and labor shortages, including shortages of truck drivers, which has caused increased labor-related costs. Knife River continues to monitor the labor markets and assess additional opportunities to enhance and support its workforce. Despite these efforts, Knife River expects labor costs to continue to increase.

Revenue includes revenue from the sale of construction materials and contracting services. Revenue for construction materials is recognized at a point in time when delivery of the products has taken place. Contracting services revenue is recognized over time using an input method based on the cost-to-cost measure of progress on a project.
Cost of revenue includes all material, labor and overhead costs incurred in the production process for Knife River's products and services. These costs are impacted by various drivers, the most significant of which includes changes in raw material costs, energy costs and salary and benefits costs. Cost of revenue also includes depreciation, depletion and amortization attributable to the assets used in the production process.
Gross profit includes revenue less cost of revenue, as defined above, and is the difference between revenue and the cost of making a product or providing a service, before deducting selling, general and administrative expenses, income taxes and interest expense.
Selling, general and administrative expenses include the costs for estimating, bidding and business development, as well as costs related to corporate functions. Selling expenses can vary depending on the volume of projects in process and the number of employees assigned to estimating and bidding activities. Other general and administrative expenses include outside services; information technology; depreciation and amortization; training, travel and entertainment; office supplies; allowance for expected credit losses; gains or losses on the sale of assets; and other miscellaneous expenses.
Other income (expense) includes net periodic benefit costs for the Company’s benefit plan expenses, other than service costs; interest income; realized and unrealized gains and losses on investments for the Company’s nonqualified benefit plans; earnings or losses on joint venture arrangements; and other miscellaneous income or expenses.
Income tax expense consists of corporate income taxes related to the sale of the Company's products and services. The effective tax rate can be affected by many factors, including changes in tax laws, regulations or rates, new interpretations of existing laws or regulations and changes to the Company's overall levels of income before income tax.
The discussion that follows focuses on the key financial measures the Company uses to evaluate the performance of its business, which include revenue, gross profit, gross margin, EBITDA and EBITDA margin. Gross margin is calculated by dividing gross profit by revenue. Gross margin reflects the percentage of revenue earned in comparison to cost. EBITDA and EBITDA margin are non-GAAP financial measures. For more information and reconciliations to the nearest GAAP measures, see the section entitled "Non-GAAP Financial Measures."

Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022
Revenue
Revenue improved $115.0 million as pricing momentum across the core product lines was supported by continued demand, increased market pricing and EDGE-related pricing initiatives. The increased pricing added $90.9 million in revenue. The Company also saw strong demand in the Mountain region, which contributed $40.6 million to its increased contracting services revenues. Partially offsetting these increases were decreased asphalt, aggregate and ready-mix concrete sales volumes of $25.3 million as a result of the Company continuing to target improved bid margins and the partial sale of non-strategic assets in southeast Texas in December 2022.
Gross profit and gross margin
Gross profit improved $84.9 million and gross margin improved 580 basis points. This increase was primarily driven by higher sales prices outpacing costs across all product lines by $39.0 million, largely as a result of market pricing and EDGE-related initiatives, including operating efficiencies and pricing optimization. Higher contracting services margins contributed $20.8 million in gross profit, which was related to improved bid margins, job productivity gains and higher revenues in the Mountain region during the quarter. Additionally, the Company benefited from higher liquid asphalt margins driven by favorable sales price increases, primarily market pricing; cost improvements; and higher sales volumes. Lower overall equipment operating costs, including fuel, also had a positive impact in the quarter.
Selling, general and administrative expenses
Selling, general and administrative expenses increased $17.6 million. As a result of the Separation from MDU Resources, the Company experienced increased recurring costs including payroll-related costs of $6.7 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors; higher insurance costs of $1.2 million; and higher professional services of $600,000, which were offset by a reduction in general corporate expenses from MDU Resources of $3.8 million, as discussed in Note 2. Also, as part of the Separation, the Company incurred one-time costs of $4.4 million, which were offset in part by income from the transition services agreement of $407,000. Further contributing to higher selling, general and administrative costs were increased payroll-related costs of $7.1 million mainly due to higher incentive accruals based on the Company's performance, higher office expenses of $600,000 and increased expected credit losses directly associated with an increase in receivable balances over 90 days and the absence of bad debt recoveries in 2022.
Interest expense
Interest expense increased $6.5 million due primarily to higher average interest rates. Interest rates were higher as a result of the Company settling related-party notes payable as part of the Separation and entering into new debt arrangements, which resulted in additional interest expense in the period of $9.4 million. Partially offsetting the increase was lower average debt balances. For additional information, see Notes 12 and 18.
31

Other income (expense)
Other income improved $1.3 million due in part to increased interest income on higher cash balances of $600,000; income resulting from the transition services agreement with MDU Resources of $400,000, as discussed in Note 18; and improved returns on the Company's nonqualified benefit plan investments.
Income tax expense
Income tax expense increased $15.1 million corresponding with higher income before income taxes.
Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $186.3 million as pricing momentum across all product lines and regions was supported by demand, increased market pricing and EDGE-related pricing initiatives. The increased pricing added $187.9 million in revenue. The Company also saw increased contracting services revenue, primarily from strong demand in the Mountain region and more available work in the Northwest region. Partially offsetting these increases were decreased ready-mix concrete, asphalt and aggregate sales volumes of $87.8 million, primarily attributable to the absence in 2023 of certain impact projects, lower internal sales volumes resulting from the strategy to target improved bid margins, project timing and the partial sale of non-strategic assets in southeast Texas in December 2022.
Gross profit and gross margin
Gross profit improved $137.6 million and gross margin improved 500 basis points. Higher sales prices outpacing costs across its product lines contributed $66.6 million in gross profit, which was largely as a result of increased market pricing and EDGE-related initiatives, including operating efficiencies and pricing optimization. Higher contracting services margins contributed $29.5 million to gross profit, primarily related to improved bid margins, job productivity gains and higher revenues in the Mountain region. Additionally, the energy services business benefited from higher liquid asphalt margins driven by favorable sales price increases, primarily market pricing; cost improvements; and higher sales volumes. Lower overall equipment operating costs, including fuel, also had a positive impact during the year.
Selling, general and administrative expenses
Selling, general and administrative expenses increased $37.1 million. As a result of the Separation from MDU Resources, the Company experienced increased recurring costs including payroll-related costs of $8.6 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors; insurance costs of $2.3 million; and professional services of $900,000, which were offset in part by a reduction in general corporate expenses from MDU Resources of $4.7 million, as discussed in Note 2. Also, as part of the Separation, the Company incurred one-time costs of $7.1 million, primarily related to professional services, insurance costs and the transition services agreement with MDU Resources, which is offset in part by income from the transition services agreement of $684,000. Further contributing to higher selling, general and administrative costs were increased payroll-related costs of $16.6 million, due in part to higher incentive accruals based on the Company's performance; higher office expenses of $1.9 million; higher information technology; and increased expected credit losses of $1.7 million directly associated with an increase in receivable balances over 90 days and the absence of bad debt recoveries in 2022.
Interest expense
Interest expense increased $22.5 million due primarily to higher average interest rates. Interest rates were higher as a result of the Company settling related-party notes payable as part of the Separation and entering into new debt arrangements, which resulted in additional interest expense in the period of $23.4 million. Partially offsetting the increase was lower average debt balances. For additional information, see Notes 12 and 18.
Other income (expense)
Other income increased $9.4 million due in part to improved returns on nonqualified benefit plan investments of $5.8 million; increased interest income of $2.6 million on higher cash balances and on the cash held in escrow for the $425.0 million of senior notes issued prior to the completion of the Separation; and income resulting from the transition services agreement with MDU Resources, as discussed in Note 18.
Income tax expense
Income tax expense increased $23.4 million corresponding with higher income before income taxes.
Business Segment Financial and Operating Data
A discussion of key financial data from Knife River’s business segments follows. This discussion is focused on the key financial measures the Company uses to evaluate the performance of its business from a segment level, which include revenue, gross profit, gross margin, EBITDA and EBITDA margin. Knife River focuses on gross margin, which is defined as gross profit as a percent of revenue, as a key metric when assessing the performance of the business as management believes that analyzing changes in costs in relation to changes in revenue provides more meaningful insight into the results of operations than examining costs in isolation. EBITDA and EBITDA margin are non-GAAP financial measures. For more information and reconciliations to the nearest GAAP measure, see the section entitled "Non-GAAP Financial Measures.”

Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022
Revenue
Revenue improved $29.0 million, largely as project work delayed by weather in the first quarter created additional volumes for asphalt products and aggregates, as well as increased workloads for the associated contracting services. Revenue increased $10.2 million for aggregates, cement and ready-mix concrete as a result of price increases to cover rising costs, increased sales of higher priced products and market improvements. Also contributing to the increase were strong cement product sales volumes to third-party customers in Alaska and strong aggregate and ready-mix concrete sales volumes of $2.9 million from increased demand in Hawaii as the local economy continues to regain momentum for Agency and residential work. Higher demand for ready-mix concrete products in northern California from an acquisition in December 2022 also had a positive impact on the quarter. These increases were offset somewhat by lower asphalt products pricing of $3.1 million due to lower liquid asphalt prices.
Gross profit and gross margin
Gross profit improved $15.4 million and gross margin improved 560 basis points, largely the result of increased volumes across all product lines contributing an additional $9.9 million in gross profit and increased pricing outpacing higher costs, as previously discussed.
EBITDA and EBITDA margin
EBITDA improved $13.0 million and EBITDA margin improved 460 basis points. These increases were the direct result of the previously discussed higher gross profit, partially offset by higher selling, general and administrative costs of $2.5 million. The increase in selling, general and administrative costs includes higher payroll-related costs of $1.6 million, largely related to higher incentive accruals based on the Company's performance; increased insurance costs of $200,000; and higher professional service fees and other miscellaneous expenses.
Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $25.3 million. Revenue across most product lines was higher as prices increased to cover rising costs and markets improved, together adding $28.8 million of revenue. Third-party cement product sales volumes also increased due to higher Agency and residential demand. In addition, the economic environment in Hawaii continued to regain momentum during the second and third quarters contributing additional aggregate and ready-mix sales volumes of $13.1 million. Partially offsetting the increased revenues was the absence in 2023 of an impact project in California of $10.9 million that affected contracting services workloads as well as asphalt volumes. Also, lower aggregate and ready-mix sales volumes experienced earlier in the year for work delayed by wet weather conditions in California, were offset in part by the significant progress made on this work during the third quarter.
33

Gross profit and gross margin
Gross profit improved $17.7 million and gross margin improved 360 basis points, largely the result of increased pricing outpacing higher costs and strong demand, as previously discussed. In addition, lower equipment operating costs, mainly fuel, had a positive impact on gross profit. Partially offsetting the increase was lower contracting services margins reducing gross profit by $2.4 million on lower revenues and cost overruns on a project in California.
EBITDA and EBITDA margin
EBITDA improved $11.3 million and EBITDA margin improved 210 basis points. These increases were the direct result of the previously discussed higher gross profit, partially offset by higher selling, general and administrative costs of $7.1 million. The increase in selling, general and administrative costs includes higher payroll-related costs of $3.9 million, due in part to higher incentive accruals based on the Company's performance; increased rent expense of $600,000; higher legal and other professional services of $600,000; higher insurance costs and building repair costs of $300,000 each; and increased other miscellaneous expenses.

Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022
Revenue
Revenue improved $4.7 million as a result of higher selling prices contributing an additional $17.2 million of revenue, which was driven by EDGE-related pricing initiatives across all product lines and increased sales of higher-priced aggregate products. Also contributing to higher revenues were increased asphalt sales volumes of $4.6 million in the north division, due in part to higher third-party sales. In addition, higher demand for contracting services of $5.8 million in the west division for Agency and railroad work and for prestress data center, manufacturing plant and infrastructure work positively impacted revenues. Partially offsetting these increases were decreased demand for asphalt paving work in the south and central divisions, which affected both asphalt product sales volumes and contracting services work by $21.4 million. Sales volumes for aggregates were also lower, largely due to project delays and lower overall demand in certain locations.
Gross profit and gross margin
Gross profit improved $6.5 million and gross margin improved 260 basis points. The increase was driven by higher sales prices outpacing costs on aggregate and asphalt products by $12.5 million, largely as a result of EDGE-related pricing initiatives and aggregates product mix. Partially offsetting the increase were the impacts of decreased sales volumes across all product lines, as previously discussed, and overall product mix.
34

EBITDA and EBITDA margin
EBITDA improved $5.1 million and EBITDA margin improved 190 basis points, directly resulting from the increased gross profit previously discussed. Partially offsetting the increase was higher selling, general and administrative expenses, including higher payroll-related costs of $1.1 million, loss on an asset disposal and higher other miscellaneous expenses.
Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $43.0 million, largely the result of EDGE-related pricing initiatives on all product lines and increased sales of higher-priced aggregate products together contributing $44.4 million. In addition, higher demand for contracting services work related to Agency and railroad projects, as well as prestress data center and other projects, contributed to the increase. Partially offsetting the increases were lower sales volumes across all product lines of $16.9 million, due in part to the timing of impact projects in 2023, weather-related delays from earlier in the year and decreased demand for asphalt paving and residential work.
Gross profit and gross margin
Gross profit improved $26.9 million and gross margin improved 380 basis points. The increase was driven by higher sales prices outpacing costs across all product lines by $24.2 million, largely as a result of EDGE-related pricing initiatives and aggregates product mix, which was offset in part by decreased volumes across all product lines, as previously discussed. Contracting services gross profit improved by $4.5 million due to the strong backlog of work established and the reduction of job losses as compared to the prior year. In addition, lower per unit fuel costs had a positive impact on gross profit.
EBITDA and EBITDA margin
EBITDA improved $22.9 million and EBITDA margin improved 310 basis points, directly resulting from the increased gross profit previously discussed. Partially offsetting the increase was higher selling, general and administrative expenses of $6.1 million. The increase includes higher payroll-related costs of $3.0 million, primarily higher incentive accruals and wages; lower asset sale gains of $1.5 million; and higher other expenses, including office expenses, dues and subscriptions, professional services and property taxes.

Revenue
Revenue improved $51.0 million, primarily the result of higher contracting services revenues from strong demand for commercial, residential, airport and Agency work, which also contributed to volume increases for asphalt and ready-mix concrete products. Pricing momentum across all product lines in response to rising costs, higher demand and growing markets contributed $21.7 million to the revenue increase. Aggregate sales volumes also increased $3.9 million, largely due to wind energy projects in Wyoming.
35

Gross profit and gross margin
Gross profit improved $19.8 million and gross margin improved 380 basis points. Higher margins on contracting services work due to higher revenues and higher bid margins contributed an additional $8.5 million in gross profit, while higher sales prices outpaced costs across all product lines by $8.4 million partly from EDGE-related initiatives, including operating efficiencies and pricing optimization. Lower overall equipment operating costs, largely related to fuel, also had a positive benefit in the quarter.
EBITDA and EBITDA margin
EBITDA improved $20.8 million and EBITDA margin improved 430 basis points, directly resulting from the increased gross profit previously discussed. Also positively impacting EBITDA was lower selling, general and administrative expenses, largely related to higher gains on asset sales.
Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $58.5 million, primarily the result of increased contracting services revenues from strong demand for commercial, residential and Agency work throughout the region, offset partially by the absence in 2023 of an impact airport project substantially completed during the second quarter of 2022. Pricing momentum across all product lines of $34.1 million, in response to rising costs, demand and growing markets, also had a positive impact on revenues. In addition, aggregate volumes benefited by $4.8 million, largely due to increased demand in Montana and wind energy projects in Wyoming. Partially offsetting these increases were lower ready-mix concrete and asphalt volumes of $7.4 million, largely the result of unfavorable weather conditions in Wyoming.
Gross profit and gross margin
Gross profit improved $24.7 million and gross margin improved 330 basis points. The improvement was the result of higher contracting services margins contributing profit of $12.0 million due to strong markets for commercial, residential and Agency work throughout the region, as well as higher sales prices outpacing costs across all product lines by $10.7 million. Lower overall equipment operating costs, including fuel, also had a positive impact on the segment. Partially offsetting these increases was $1.4 million of higher depreciation expense.
EBITDA and EBITDA margin
EBITDA improved $26.3 million and EBITDA margin improved 370 basis points, directly resulting from the increased gross profit previously discussed.

Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022
Revenue
Revenue improved $10.8 million resulting from higher selling prices contributing an additional $30.1 million in revenue, largely due to pricing initiatives on all product lines, as well as product mix. Asphalt and aggregate sales volumes decreased $20.6 million, largely as the segment continues to target improved bid margins on smaller projects which also impacts internal sales volumes, as well as the absence of an impact project in South Dakota during 2022. Overall ready-mix concrete volumes were flat, with strong volumes in South Dakota from commercial and third-party sales being offset by decreased residential demand in Minnesota.
Gross profit and gross margin
Gross profit improved $15.6 million and gross margin improved 440 basis points. Higher contracting services margins contributed $10.3 million in gross profit, largely related to improved bid margins across the region and efficient execution of work leading to job productivity gains on a large concrete and asphalt paving job. Also, higher sales prices across all product lines outpaced cost increases by $7.2 million. Lower overall equipment operating costs, largely related to fuel, also had a positive benefit in the quarter of approximately $2.1 million. Partially offsetting these increases were lower aggregates and asphalt volumes, as previously discussed.
EBITDA and EBITDA margin
EBITDA improved $11.9 million and EBITDA margin improved 320 basis points, directly resulting from the increased gross profit previously discussed. Partially offsetting the increase was higher selling, general and administrative expenses of $3.7 million, largely higher payroll-related costs of $2.5 million, including higher wages and incentive and profit sharing accruals based on the Company's performance; decreased gains on asset sales of $500,000; and increased bad debt expense.
Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $29.3 million as a result of higher selling prices across all product lines providing $51.8 million of additional revenue, largely due to EDGE-related pricing initiatives. Contracting services revenue saw a benefit of $10.1 million from improved bid margins across the region and a large concrete and asphalt paving job. Asphalt and aggregate sales volumes decreased $29.9 million, largely as the segment continues to target improved bid margins on projects which also impacts internal sales volumes, as well as the absence of an impact project in South Dakota. Overall ready-mix concrete volumes were flat, as strong volumes in South Dakota from commercial and paving projects and North Dakota from an impact project were mostly offset by softening residential demand in Minnesota.
37

Gross profit and gross margin
Gross profit improved $27.1 million and gross margin improved 460 basis points, largely due to higher contracting services margins of $14.0 million related to improved bid margins, impact projects and job productivity gains, as well as higher sales prices across all product lines outpacing cost increases by $11.6 million. Lower overall equipment operating costs, largely fuel, also had a positive benefit in the quarter of approximately $6.0 million. Partially offsetting these increases were lower aggregate and asphalt sales volumes, as previously discussed.
EBITDA and EBITDA margin
EBITDA improved $21.0 million and EBITDA margin improved 350 basis points, directly resulting from the increased gross profit previously discussed. Partially offsetting the increase was higher selling, general and administrative expenses of $6.3 million, primarily higher payroll-related costs of $4.7 million, including higher incentive and profit sharing accruals based on the Company's performance, as well as decreased gains on asset sales of $500,000; increased insurance costs of $300,000; and increased other miscellaneous expenses.

Revenue
Revenue improved $19.5 million, due largely to higher revenues from liquid asphalt. Timing of projects in certain markets, as well as market strength, drove liquid asphalt volumes up, while market pricing provided a benefit of $9.5 million for the quarter. In the South region, additional asphalt paving work and favorable weather in Texas contributed $6.1 million in revenue and higher selling prices across all product lines contributed $3.8 million. Additionally, the South region's Honey Creek quarry contributed additional aggregate volumes in the quarter as it became fully operational in the second quarter of 2023. Partially offsetting the increases were decreased ready-mix concrete and aggregates sales of $10.2 million due to a partial sale of non-strategic assets in southeast Texas in December 2022.
Gross profit and gross margin
Gross profit improved $27.6 million and gross margin improved 1,830 basis points, primarily due to higher liquid asphalt margins resulting from cost improvements and favorable sales price increases driven by market pricing, as well as the higher sales volumes previously mentioned. In addition, higher sales prices across all product lines in the South region contributed $2.9 million to gross profit, as previously discussed. Partially offsetting the increase in the South region was a decrease in aggregates and ready-mix concrete volumes, which resulted in a reduction to gross profit of $2.4 million, largely as a result of the partial sale of non-strategic assets in southeast Texas in December 2022.
EBITDA and EBITDA margin
EBITDA improved $18.5 million and EBITDA margin improved 1,260 basis points. The increase in EBITDA was the direct result of increased gross profit previously discussed, partially offset by higher selling, general and administrative costs of $9.8 million. As a result of the Separation from MDU Resources, the Company experienced increased payroll-related costs of $6.7 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors, and higher professional services of $600,000, which were offset by a reduction in general corporate expenses from MDU Resources of $3.8 million, as discussed in Note 2. Also, as part of the Separation, the Company incurred one-time costs of $4.4 million, primarily related to professional services, insurance costs and the transition services agreement with MDU Resources, which was offset in part by income from the transition services agreement of $407,000. Further contributing to higher selling, general and administrative costs were increased payroll-related costs of $1.9 million due to higher incentive accruals based on the Company's performance.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022
Revenue
Revenue improved $30.2 million, largely driven by higher liquid asphalt revenue of $19.3 million because of market pricing, along with higher volumes from additional sales opportunities across most of its primary markets. The South region benefited from higher selling prices across all product lines, higher contracting services revenues of $8.6 million related to asphalt paving work and higher aggregate sales volumes as a result of the Honey Creek quarry operations. Partially offsetting these increases were decreased aggregate and ready-mix concrete sales of $22.8 million due to the partial sale of non-strategic assets in southeast Texas in December 2022.
Gross profit and gross margin
Gross profit improved $41.2 million and gross margin improved 1,320 basis points, primarily due to higher liquid asphalt margins resulting from favorable sales price increases driven by market pricing, cost improvements and higher sales volumes. The South region's gross profit increased $5.6 million from higher sales prices for asphalt and ready-mix concrete while contracting services margins increased as a result of improved bid margins. Partially offsetting the improvements was the impact of decreased ready-mix concrete volumes as a result of the partial sale of non-strategic assets in southeast Texas in December 2022.
EBITDA and EBITDA margin
EBITDA improved $29.7 million and EBITDA margin improved 1,030 basis points. The increase in EBITDA was the direct result of increased gross profit previously discussed, partially offset by higher selling, general and administrative costs of $17.7 million. As a result of the Separation from MDU Resources, the Company experienced increased recurring costs including payroll-related costs of $8.6 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors; insurance costs of $1.5 million; and professional services of $900,000, which were offset in part by a reduction in general corporate expenses from MDU Resources of $4.7 million, as discussed in Note 2. Also, as part of the Separation, the Company incurred one-time costs of $7.1 million, primarily related to professional services, insurance costs and the transition services agreement with MDU Resources, which was offset in part by income from the transition services agreement of $684,000. Further contributing to higher selling, general and administrative costs were increased payroll-related costs due to higher incentive accruals based on the Company's performance.
Liquidity and Capital Resources
At September 30, 2023, Knife River had cash and cash equivalents of $84.0 million and working capital of $586.4 million. Working capital is calculated as current assets less current liabilities. Following the Separation, Knife River’s cash management, capital structure and liquidity sources have changed significantly. Knife River implemented its own centralized cash management model and intends to use cash on hand and third-party credit facilities to fund day-to-day operations. As of September 30, 2023, the Company believes it has sufficient liquid assets, cash flows from operations and borrowing capacity to meet its financial commitments, debt obligations and anticipated capital expenditures for at least the next 12 months.
Given the seasonality of its business, the Company typically experiences significant fluctuations in working capital needs and balances throughout the year. Working capital requirements generally increase in the first half of the year as the Company builds up inventory and focuses on preparing equipment and facilities and other start-up costs for its construction season. Working capital levels then decrease as the construction season winds down and the Company collects on receivables.
Knife River’s ability to fund its cash needs will depend on the ongoing ability to generate cash from operations and obtain debt financing with competitive rates. Knife River relies on access to capital markets as sources of liquidity for capital requirements not satisfied by cash flows from operations, particularly in the first half of the year due to the seasonal nature of the industry. Knife River’s principal uses of cash in the future will be to fund its operations, working capital needs, capital expenditures, repayment of debt and strategic business development transactions.
On April 25, 2023, Knife River issued $425.0 million of 7.75 percent senior notes due May 1, 2031. On May 31, 2023, Knife River entered into a senior secured credit agreement consisting of a $275.0 million term loan, with a balance outstanding of $273.3 million at September 30, 2023, and a $350.0 million revolving credit facility, with no outstanding borrowings at September 30, 2023. Each of the agreements under the senior secured credit agreement have a SOFR-based interest rate and a maturity date of May 31, 2028. For more information on the debt agreements and covenant restrictions, see Note 12.
Capital expenditures
Knife River currently estimates total 2023 capital expenditures to be $125.0 million, of which there is approximately $50.0 million remaining at September 30, 2023. These expenditures relate primarily to routine replacement and maintenance of vehicles and equipment, building improvements, aggregate reserves and storage facilities updates.
The Company continues to evaluate the potential for future acquisitions and other growth opportunities that would be incremental to the outlined capital program; however, these opportunities are dependent upon the availability of economic conditions. It is anticipated that all of the funds required for capital expenditures for 2023 will be funded by various sources, including internally generated funds and credit facilities.

Net cash provided by operating activities:$152.9 $39.4 $113.5 
Cash provided by operating activities at September 30, 2023, increased $113.5 million, largely related to increased earnings in 2023 and lower working capital needs. Cash used by working capital components totaled $135.7 million for the nine months ended September 30, 2023, compared to $154.9 million for the nine months ended September 30, 2022. This reduction in cash usage was driven largely by the lower payments on operating expenses at the end of the period, higher accrued interest payments on long-term debt, and decreased liquid asphalt inventory balances, partially offset by increased accounts receivable balances associated with higher revenues during the quarter. In addition, the timing of insurance costs associated with the captive insurer had a positive impact on cash.

The decrease in cash flows provided by financing activities for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, was largely related to the changes in debt as a result of the Separation. For further information, see Note 18.
Material cash requirements
There were no material changes in the Company's contractual obligations from those reported in the Company's Registration Statement on Form 10 other than as set forth below. For more information on the Company's contractual obligations for related-party notes payable, operating leases and purchase commitments, see the Material Cash Requirements section in the Management's Discussion and Analysis of Financial Condition and Results of Operations section in the Company's Registration Statement on Form 10.
Material short-term and long-term cash requirements of the Company include repayment of third-party long-term debt and related interest payments, related-party notes payable and related interest payments, payments on operating lease agreements, payments of obligations on purchase commitments and asset retirement obligations.
At September 30, 2023, the Company's purchase commitments reflected an increase of approximately 36 percent from the balance at December 31, 2022. This increase is primarily from the Company committing to a three-year cement contract. Due to the seasonality of work and the third quarter being its peak construction season, the Company's purchase commitments saw an expected decrease from the balance at June 30, 2023. The Company expects purchase commitments to continue to decrease throughout the remainder of 2023 as obligations continue to be satisfied during the construction season.
At September 30, 2023, the Company's long-term debt reflected an increase of approximately $221.7 million from the balance at December 31, 2022. This increase is due to the Company paying off its short-term debt, and replacing it with long-term debt in preparation of the Separation.
At September 30, 2023, the Company's total estimated interest payments over the life of its debt reflected an increase of approximately $250.5 million from the total estimated interest payments at December 31, 2022. This increase is due to the rising interest rate environment in 2023 and higher rate debt incurred by the Company in preparation of the Separation. The Company's average interest rate has increased from 3.62% on December 31, 2022 to 6.90% on September 30, 2023. Estimated interest payments outstanding over the life of the loans was as follows:

Defined benefit pension plans
The Company has noncontributory qualified defined benefit pension plans for certain employees. Various assumptions are used in calculating the benefit expense (income) and liability (asset) related to these plans, as such costs of providing these benefits bear the risk of changes as they are dependent upon assumptions of future conditions.
There were no other material changes to the Company's qualified noncontributory defined benefit pension plans from those reported in the Company's Registration Statement on Form 10 other than the Company contributed approximately $1.2 million to its pension plans during the third quarter. The contribution was largely as a result of the decline in asset values in 2022 decreasing the funded status of the plans. For more information, see Note 17 of the Audited Annual Consolidated Financial Statements in the Company's Registration Statement on Form 10.

Non-GAAP Financial Measures
The Business Segment Financial and Operating Data includes financial information prepared in accordance with GAAP, as well as EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA Margin financial measures. Knife River defines EBITDA as net income before interest expense, taxes and depreciation, depletion and amortization, and EBITDA margin as EBITDA as a percentage of revenues. Knife River defines Adjusted EBITDA as EBITDA, further adjusted to exclude unrealized gains and losses on benefit plan investments, stock-based compensation and one-time Separation costs, and Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of revenues.
EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA Margin, including those measures by segment, are considered non-GAAP financial measures and are most directly comparable to the corresponding GAAP measures of net income, net income margin, gross profit and gross margin. Knife River believes these non-GAAP financial measures, in addition to corresponding GAAP measures, are useful to investors by providing meaningful information about operational efficiency compared to its peers by excluding the impacts of differences in tax jurisdictions and structures, debt levels and capital investment. Management believes Adjusted EBITDA is a useful performance measure because it allows for an effective evaluation of the Company's operating performance by excluding stock-based compensation and unrealized gains and losses on benefit plan investments as they are considered non-cash and not part of the Company's core operations. The Company also excludes the one-time, non-recurring costs associated with the Separation as those are not expected to continue. Rating agencies and investors also use EBITDA and Adjusted EBITDA to calculate Knife River’s leverage as a multiple of EBITDA and Adjusted EBITDA. Additionally, EBITDA and Adjusted EBITDA are important financial metrics for debt investors who utilize debt to EBITDA and debt to Adjusted EBITDA ratios. Knife River's management believes EBITDA and EBITDA margin, including those measures by segment, are useful performance measures because they provide clarity as to the operational results of the Company. Knife River’s management uses these non-GAAP financial measures in conjunction with GAAP results when evaluating its operating results internally and calculating employee incentive compensation, and leverage as a multiple of EBITDA and Adjusted EBITDA to determine the appropriate method of funding operations of the Company.
EBITDA is calculated by adding back income taxes, interest expense and depreciation, depletion and amortization expense to net income. EBITDA margin is calculated by dividing EBITDA by revenues. Adjusted EBITDA is calculated by adding back unrealized gains and losses on benefit plan investments, stock-based compensation and one-time Separation costs, to EBITDA. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenues. These non-GAAP financial measures are calculated the same by segment and consolidated and should not be considered as alternatives to, or more meaningful than, GAAP financial measures such as net income or net income margin and are intended to be helpful supplemental financial measures for investors’ understanding of Knife River’s operating performance. Knife River’s non-GAAP financial measures are not standardized; therefore, it may not be possible to compare these financial measures with other companies’ EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA Margin measures having the same or similar names.
The following information reconciles consolidated and segment net income to EBITDA and EBITDA to Adjusted EBITDA and provides the calculation of EBITDA margin and adjusted EBITDA margin. Interest expense, net, is net of interest income that is included in other income on the Consolidated Statements of Operations.

New Accounting Standards
For information regarding new accounting standards, see Note 2, which is incorporated by reference.
Critical Accounting Estimates
Knife River's critical accounting estimates include impairment testing of goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; revenue recognized using the cost-to-cost measure of progress for contracts; actuarially determined benefit costs; and tax provisions. There were no material changes in the Company's critical accounting estimates from those that were previously reported in the Company's Registration Statement on Form 10.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
The Company is exposed to the impact of market fluctuations associated with interest rates and commodity prices. The Company has policies and procedures to assist in controlling these market risks and from time to time has utilized derivatives to manage a portion of its risk.
Interest rate risk
Rising interest rates have resulted in, and will likely continue to result in, higher borrowing costs on new debt and existing variable interest rate debt. Knife River entered into a senior secured credit agreement with variable rate debt arrangements at the time of the Separation, which could impact the interest expense recognized in future periods. For additional information on the debt agreements the Company has entered into, see the section entitled "Liquidity and Capital Resources". At September 30, 2023, the Company had $273.3 million in term loan borrowings under the credit agreement at the rate in effect at this time of 7.52%. A hypothetical increase of 1 percent on the interest rate of the term loan borrowings would increase interest expense by $2.7 million over the next 12 months.
At September 30, 2023, the Company had no outstanding interest rate hedges.
Commodity price risk
There were no material changes to commodity price risk faced by the Company from those reported in the Company's Registration Statement on Form 10.
