Upon the completion of the Separation, we implemented our own financing agreements with lenders.

For additional information on our current debt financing, see Item 8 - Note 9.

All intercompany balances and transactions between the businesses comprising Knife River have been eliminated in the accompanying audited consolidated financial statements.

In the fourth quarter of 2023, the Company completed a reorganization of its reporting structure, which resulted in changes being made to the management of its business to best align with its strategies.

As a result of the reorganization, the liquid asphalt and related services portion of the Pacific segment’s businesses are now reported under the Energy Services segment.

In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central.

All periods have been recast to conform with the revised presentation.

Market Conditions and Outlook

Knife River’s markets remain resilient and construction activity remains generally strong despite general and economic challenges in the United States, such as higher interest rates, inflation, transportation disruptions and supply-chain constraints.

With approximately 77 percent of its contracting services revenue from public-sector projects, the Company has been able to balance the cyclical nature of its private-sector customers.

While Knife River continued to experience 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 "Item 1A.

Our markets remain resilient, and construction activity remains generally strong.

Approximately 80 percent of our contracting services revenue each year comes from public-sector projects, enhancing stability through market cycles.

Total $ 745.6 $ 662.2 $ 818.9

Although backlog as of December 31, 2023, is lower than the prior period, expected margins are greater as the Company continues to implement EDGE and pursue higher-margin work.

Of the $662.2 million of backlog at December 31, 2023, the Company expects to complete an estimated $610.8 million during 2024.

Approximately 84 percent of the Company's backlog as of December 31, 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.

Further, there continues to be infrastructure development, as discussed later, which is expected to provide bidding opportunities in the Company’s markets throughout 2024.

Period-over-period increases or decreases in backlog are not indicative of future revenues, margins, net income or EBITDA.

While the Company believes the current backlog of work remains firm, prolonged delays in the receipt 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.

Backlog as of December 31, 2024, is 13 percent higher than the prior period and expected margins are comparable.

Of the $745.6 million of backlog at December 31, 2024, we expect to complete an estimated $630.5 million during 2025.

Approximately 86 percent of our backlog as of December 31, 2024, relates to publicly funded projects, including street and highway construction projects, which are driven primarily by public works projects for state departments of transportation.

Risk Factors” for a list of factors that can cause revenues to be realized in periods and at levels that are different from originally projected.

Risk Factors” for a list of factors that can cause revenues or margins 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.

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.

States have moved forward with allocating funds from federal programs, such as the IIJA, which is authorized to provide $1.2 trillion in funding from 2022 through 2026.

As of November 2024, approximately 43 percent of IIJA formula funding has yet to be obligated to projects in our market areas.

Also in 2024, six of the 14 states where we operate have passed ballot measures to increase their transportation investment.

Additionally, DOT budgets in the states where we operate remain strong, which favorably affects our bidding season in early 2025.

We continue to monitor the implementation and impact of these legislative items and the state DOT budgets.

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.

As part of this strategy, Knife River has increased its product pricing over the past year and is

targeting higher-margin bidding opportunities.

Knife River also provided company-wide training on its pricing initiatives in the fourth quarter of 2023.

In addition, the Company established dedicated teams that assist with implementing cost-savings initiatives and production modifications 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, liquid asphalt and cement 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 segment is 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 its 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 a lengthened 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 2023, the Company experienced a longer construction season in the fourth quarter due to mild weather conditions across the western and northern United States.

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.

As a people-first company, Knife River continually takes steps to address the challenge of recruitment and retention of employees.

Knife River continues to monitor the labor markets and assess additional opportunities to enhance and support its workforce.

To help attract new workers to the construction industry and enhance the skills and safety performance of its current employees, Knife River owns and 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.

The following table summarizes some of the classes taught at the Knife River Training Center.

* Heavy equipment includes, but is not limited to, articulated truck, track type tractor, bulldozer, hydraulic excavator, snowcat, backhoe loader, off highway truck, motor grader, roller, wheel loader and skid steer loader.

Our management team continually monitors our margins and has been proactive in applying strategies to increase margins to support our long-term profitability goals and to create shareholder value.

In 2023, we began implementing EDGE initiatives and established teams to deliver training, assist with targeting higher-margin bidding opportunities across the regions and pursue growth opportunities, as well as identifying ways to increase efficiencies and reduce costs.

In 2023, its first year of operation, the Materials Process Improvement Team (Materials PIT Crew) traveled to 10 locations throughout our operational footprint, visiting 67 individual aggregate, asphalt and ready-mix concrete plants.

In 2024, the team traveled to eight additional locations and 58 individual plants, in addition to follow-up trips to sites visited in the prior year.

The Materials PIT Crew also hosted a Plant Equipment Best Practices training seminar at our training center in Oregon in December of 2024.

This training was attended by approximately 150 front line plant operators and maintenance personnel and was supported by our internal subject matter experts and a number of plant equipment manufacturers.

Also in 2024, a broader process improvement framework was established with teams focused on standardization, commercial excellence and operational excellence, due in part to the success of the Materials PIT Crew.

Acquisitions .

Our management team has also continued to evaluate growth opportunities, both through organic growth and acquisitions they believe will generate shareholder value.

In 2024, we invested $131.0 million of capital to close on six acquisitions.

The acquisitions include aggregate-specific purchases in key markets and expanding our ready-mix and liquid asphalt operations.

In November 2024, we purchased the business of Albina Asphalt, which has operations in Washington, Oregon and California and expanded the footprint of our high-margin liquid asphalt materials product line.

In December 2024, we also entered into a definitive agreement to acquire Strata Corporation, a leading construction materials and contracting services provider in North Dakota and northwestern Minnesota.

The acquisition of Strata is expected to close in the first half of 2025, subject to customary closing conditions.

In addition to cash on hand, we intend to use a portion of the proceeds from the issuance of a new $500 million Term Loan B facility to fund the purchase of Strata.

As a people-first company, we continually take steps to address safety, recruitment and retention of our employees.

Safety is one of our core values, and as part of our safety culture, we believe that all incidents and injuries are preventable.

We continue to advance our culture of safety through engagement, and empowering our team members to take action and make meaningful changes that improve the well-being of themselves and others.

Focusing on the development and retention of our employees is key to our success.

We continue to deploy resources to attract, develop and retain qualified and diverse talent.

As the United States faces shortages in the availability of individuals to fill careers in our industry, we have taken significant steps to showcase construction as a career of choice.

We own and operate a state-of-the-art training facility, the Knife River Training Center, which is used corporate-wide to enhance the skills of both our new and existing employees through classroom education and hands-on experience.

One of the most popular courses at the Knife River Training Center is the commercial driver's license training, which is helping to address an industry-wide labor shortage.

The training facility also offers a variety of courses around leadership development for all our employees.

We employ professional instructors as part of our Training and Development team, which is based out of the Knife River Training Center.

This team has a long-standing tradition of offering quality training to both frontline and leadership-level employees.

In 2024, the team provided training to nearly 1,100 students through 74 separate courses.

Training courses include:

commercial driver’s license/new truck driver, experienced truck driver, new and experienced equipment operator, sales, leadership/facilitator development and construction industry engagement.

2024 Compared to 2023

Revenue improved $295.6 million as increased pricing added $217.3 million in revenue across all regions and product lines, supported by demand, increased market pricing and EDGE-related pricing initiatives.

The Company also saw increased contracting services revenue in most regions, especially in the Mountain and Northwest regions that benefited from strong demand and more available work.

Revenue increased $68.7 million as increased pricing added $122.9 million during the year as a result of our pricing initiatives across all product lines, except liquid asphalt.

In 2024, we saw price increases of low-double-digits for ready-mix concrete, high-single-digits for aggregates and low-single digits for asphalt.

Our contracting services revenue also increased in most regions, particularly in the Mountain, Northwest and Pacific regions, as we benefited from additional public-agency work and timing of projects.

Partially offsetting these increases were decreased ready-mix, aggregate and asphalt sales volumes of $120.5 million, primarily due to EDGE-related initiatives of quality over quantity of work, timing of projects and lower demand for private projects.

Liquid asphalt revenue decreased due to lower pricing as a result of reduced supply input costs across our market areas.

Gross Profit and Gross Margin

Gross profit improved $30.9 million while gross margin improved 70 basis points.

Contracting services margins increased 160 basis points as we saw an increase in revenues along with improved bid margins and favorable project execution during the year.

Also contributing to the improvement was higher margins on asphalt, aggregates and ready-mix concrete as higher sales prices outpaced costs while volumes declined as we continue to choose quality of work over quantity of work.

Liquid asphalt continued to see a reduction in gross profit, as a result of lower revenues due to the pricing decrease.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $11.1 million.

Our reportable segments had higher costs of $4.1 million, which was primarily related to higher payroll-related costs, largely due to additional staffing, competitive wage increases, and higher professional services.

These increases were offset in part by higher asset sale gains of $3.4 million and the absence of non-cash asset impairments of $5.8 million on aggregate sites discussed in Item 8 - Note 2.

Corporate Services had increased costs of $7.0 million.

The increase in costs for non-Separation related expenses totaled $7.4 million, which was primarily higher due diligence and integration costs related to corporate development and completed acquisitions of $7.5 million and higher information technology costs of $3.4 million.

These costs were partially offset by lower payroll-related costs of $2.4 million, largely due to lower bonus accruals, and a reduction in insurance loss reserves at our captive insurer of $2.6 million.

As a result of the Separation, we experienced higher recurring costs as a publicly traded company of $6.3 million, including payroll-related costs of $9.5 million, largely due to additional staff and stock-based compensation expenses for the management team and board of directors;

information technology costs of $2.8 million;

professional services of $1.8 million;

and fees of $750,000 primarily related to fees on new debt issued in conjunction with the Separation, partially offset by a reduction in general corporate expenses from MDU Resources of $8.9 million.

We also incurred less one-time costs of $6.5 million primarily consisting of insurance costs related to the Separation and the transition services agreement with MDU Resources.

Interest Expense

Interest expense decreased $2.9 million due primarily to lower average debt balances, offset by higher average interest rates.

Other Income (Expense)

Other income (expense) increased $3.0 million, primarily due to increased interest income on higher cash balances.

Income Tax Expense

Income tax expense increased $6.9 million corresponding with higher income before income taxes.

2023 Compared to 2022

Revenue improved $295.6 million as increased pricing added $217.3 million across all regions and product lines, supported by demand, increased market pricing and EDGE-related pricing initiatives.

We also saw increased contracting services revenue in most regions, especially in the Mountain and Northwest regions that benefited from strong demand and more available work.

Higher liquid asphalt sales volumes also contributed to the increased revenue.

2022 Compared to 2021

Revenue increased $305.8 million, largely driven by increased revenues across all product lines as the business benefited from higher average selling prices of nearly $250 million, largely in response to inflationary pressures.

Aggregate sales volumes provided an additional $10.2 million, due mainly to recent acquisitions contributing 2.2 million tons, offset in part by lower volumes in certain segments.

Asphalt sales volumes increased $7.2 million from higher demand in Minnesota and North Dakota, along with the Mountain and Pacific segments, partially offset by lower volumes in Texas due to less available paving work.

Contracting revenues increased $170.2 million across most segments as a result of more available agency and commercial work, recent acquisitions in the Northwest segment contributing $27.9 million, more available paving work in the Mountain segment along with Minnesota and North Dakota and higher contract values in all segments as a result of inflationary pressures.

The business was impacted by lower ready-mix concrete sales volumes of $38.5 million across all segments, resulting from lower residential demand and fewer impact projects.

The business also saw decreased volumes for other products, largely related to decreased demand for liquid asphalt.

Gross Profit and Gross Margin

Gross profit increased by $13.9 million and gross margin decreased 140 basis points.

The increase in gross profit was primarily as a result of increased average selling prices to offset higher costs, largely due to inflationary pressures.

The decrease in gross margin was primarily attributable to decreases for asphalt, other products and contracting services due to higher costs discussed later, including higher liquid asphalt, labor and fuel costs.

Partially offsetting these decreases were increased gross margins on aggregates and ready-mix concrete as a result of higher average selling prices, as previously discussed, driven by higher operating costs across the segments, mostly the result of inflationary pressures.

All lines of business were impacted by the higher costs, which include higher liquid asphalt costs of $59.3 million;

higher labor costs of $32.0 million;

higher fuel costs of $42.6 million;

and higher cement costs of $20.7 million.

In addition, contributions from recent acquisitions of $12.9 million had a positive impact on gross margin for the aggregates and contracting services.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $10.7 million, largely resulting from higher payroll-related costs of $11.6 million, partially resulting from inflationary pressures;

higher travel expenses of $2.3 million;

higher office expenses of $1.7 million;

higher professional fees of $1.7 million, partially due to increased legal and audit fees;

decreased recovery of bad debt of $1.4 million;

and increased safety and training costs.

These increases were offset in part by higher net gains on asset sales of $7.5 million.

Interest Expense

Interest expense increased $10.9 million related to higher debt balances to fund recent acquisitions and higher working capital needs, along with higher average interest rates.

Other Income (Expense)

Other income (expense) decreased $6.7 million, primarily resulting from lower returns on the Company's nonqualified benefit plan investments.

Income Tax Expense

Income tax expense decreased $800,000 as a result of lower income before income taxes.

Business Segment Financial and Operating Data

A discussion of key financial data from Knife River’s business segments follows.

Knife River provides segment level information by revenue, gross profit, gross margin, EBITDA and EBITDA margin as these are measures of profitability used by management to assess operating results.

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.”

In the fourth quarter of 2023, the Company completed a reorganization of its reporting structure, which has resulted in changes being made to the management of its business to best align with its strategies.

Based on how the chief operating decision maker manages the Company, the reportable segments are:

Pacific, Northwest, Mountain, Central and Energy Services.

The Company also has the Corporate Services segment.

The Corporate Services segment provides accounting, legal, treasury, information technology, human resources and certain corporate expenses that support its operating segments.

As a result of the reorganization, the liquid asphalt and related services portion of the Pacific segment’s businesses are now reported under the Energy Services segment.

In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central.

All periods have been recast to conform with the revised presentation.

A discussion of key financial data from our business segments follows.

We provide segment level information by revenue, EBITDA and EBITDA margin as these are measures of profitability used by management and our chief operating decision maker to assess operating results.

On January 1, 2025, we completed a reorganization of our operating segments, including the management of the segments, to align with our business strategy.

In the first quarter of 2025, we will begin reporting our financial information under four operating segments:

West, Mountain, Central and Energy Services.

Under the new operating structure, the previous Pacific and Northwest operating segments will become the West operating segment and the North Central and South operating segments will become the Central operating segment.

2024 Compared to 2023

Revenue improved $44.1 million, across most product lines and was higher as a result of increased prices to cover rising costs and from the early stages of EDGE-related pricing implementation, as well as increased sales of higher priced products, adding $32.0 million.

The segment saw strong cement product sales volumes to third-party customers in Alaska and strong aggregate sales volumes of $6.0 million, primarily from increased demand in Hawaii as the local economy continues to regain momentum for public and private work.

Ready-mix concrete sales volumes

increased in northern California as a result of an acquisition in December 2022, which were offset in part by lower sales volumes in Alaska due to fewer projects over the prior year.

Our revenue increased $30.9 million in 2024.

Price increases across all product lines as a result of EDGE-related initiatives and aggregate product mix contributed $36.9 million of additional revenue in 2024.

We also had a $15.5 million increase in contracting services, primarily driven by large public agency-related construction projects in northern California.

Partially offsetting the increased revenue was reduced volumes of $27.6 million across the remaining product lines, partly due to increased competition in the California market as well as reduced demand in marine construction.

We saw an increase in EBITDA of $3.7 million, while EBITDA margin decreased 10 basis points.

The increase in EBITDA was due in part to additional gross profit in northern California’s contracting services, primarily related to increased public agency-related construction projects and operational efficiencies recognized during the year.

Also contributing to the increase was lower selling, general and administrative expenses of $2.3 million due to a gain of $2.2 million on equipment sales in California and the absence of a non-cash impairment in 2023 of $2.2 million on a leased aggregate site, as discussed in Item 8 - Note 2, offset in part by higher professional services.

Gross profit on our construction materials decreased $4.6 million in 2024 as a result of lower volumes and higher production costs.

2023 Compared to 2022

Our revenue increased $44.1 million in 2023.

This increase was across most product lines and was the result of increased prices to cover rising costs and the early stages of EDGE-related pricing implementation, as well as increased sales of higher priced products, adding $32.0 million.

We saw strong cement product sales volumes to third-party customers in Alaska and strong aggregate sales volumes of $6.0 million, primarily from increased demand in Hawaii as the local economy continues to regain momentum for public and private work.

Ready-mix concrete sales volumes increased in northern California as a result of an acquisition in December 2022, which were offset in part by lower sales volumes in Alaska due to fewer projects over the prior year.

Partially offsetting the increased revenues was the absence in 2023 of an impact project in California of $11.2 million, which affected both contracting services workloads and asphalt volumes.

Northern California experienced mild weather in the fourth quarter which also contributed to a strong finish to the year.

Gross Profit and Gross Margin

Gross profit improved $22.9 million while gross margin improved 380 basis points, largely the result of increased pricing outpacing costs and strong demand, as previously discussed.

The segment also experienced lower fuel and asphalt oil costs.

Partially offsetting the increase was lower contracting services margins reducing gross profit by $1.9 million as a result of cost overruns on a project in California.

EBITDA and EBITDA Margin

EBITDA improved $12.2 million and EBITDA margin improved 170 basis points.

These improvements are the direct result of the previously discussed gross profit, offset in part by higher selling, general and administrative expenses of $11.6 million.

The increased selling, general and administrative expenses includes higher payroll-related costs of $5.9 million, due in part to higher incentive accruals based on the Company’s performance;

and other miscellaneous expenses.

2022 Compared to 2021

Revenue improved $21.3 million, largely from higher average selling prices for ready-mix concrete, asphalt, aggregates and cement, largely in response to inflationary pressures, contributing approximately $23.2 million.

Revenues were also positively impacted from increased asphalt volumes of 9.4 percent, primarily related to a large project in Northern California.

Contracting services revenues were up 1.5 percent, which provided an additional $1.9 million during the period, largely in the northern California market from a large project and increases in contract pricing, due in part to inflationary pressures.

Partially offsetting these increases were decreased aggregate sales volumes of $3.4 million related to decreased demand in northern California and decreased ready-mix concrete sales volumes of $3.0 million related to decreased demand in Alaska and Hawaii.

Gross Profit and Gross Margin

Gross profit decreased $8.9 million and gross margin decreased 300 basis points.

Margins decreased across most product lines and contracting services as a result of a downturn in the Hawaiian economy, a lack of large rock projects and less residential work in California.

In addition, the segment experienced higher costs of $30.2 million, largely the result of inflationary pressures, including fuel, labor, material and production costs.

EBITDA and EBITDA Margin

EBITDA decreased $13.9 million and EBITDA margin decreased 410 basis points.

2024 Compared to 2023

Revenue improved $65.9 million, largely the result of EDGE-related pricing initiatives on all product lines, which together contributed $52.0 million.

In addition, higher demand for contracting services work related to Agency and railroad projects, as well as prestress data center and other projects, accounted for an increase in revenues of $37.7 million.

Our revenue increased $26.3 million in 2024, most of which was due to large public agency-related construction projects driving an increase in contracting services and asphalt sales volumes.

In addition, improved pricing on ready-mix concrete and aggregates provided $38.1 million more in revenue.

Offsetting the increases were a decrease

in ready-mix and aggregates sales volumes due to EDGE-related pricing initiatives and lower demand in the residential and commercial markets.

We saw an increase in both EBITDA of $28.7 million and EBITDA margin of 340 basis points.

These improvements resulted from higher construction gross profit of $15.5 million due to favorable job execution, efficiencies gained at our Spokane prestress facility and more available public agency work.

We also benefited from improved ready-mix concrete margins as a result of increased pricing and favorable project execution in southern Oregon and increased asphalt margins due to lower asphalt oil and variable production costs.

In addition, our selling, general and administrative expenses decreased $3.0 million due to the absence of a non-cash asset impairment in 2023 of $3.6 million on an aggregate site, as discussed in Item 8 - Note 2;

higher gains on the sale of equipment;

lower bad debt expense of $500,000;

and lower professional services, offset in part by higher payroll-related costs of $3.6 million due to additional staffing.

Our revenue decreased $6.9 million in 2024 as a result of lower asphalt and ready-mix concrete volumes and $15.1 million less contracting services revenues, largely due to our EDGE-related initiative of quality of work over quantity of work.

The north central region also saw less contracting services work and asphalt sales volumes in 2024 related to the timing of projects with more work completed in late 2023 due to favorable weather later in the construction season.

Partially offsetting the decrease in volumes was the benefit of higher prices on ready-mix concrete and asphalt of $24.4 million with the continued implementation of EDGE-related pricing initiatives.

Overall, our aggregate sales volumes across the segment increased $4.7 million.

We saw an increase in EBITDA of $15.0 million and EBITDA margin of 200 basis points in 2024.

These improvements are the result of increased margins across all product lines, largely due to continued EDGE-related pricing initiatives.

Our contracting services work contributed an additional $4.9 million of gross profit, largely due to higher margin work, disciplined project bidding and favorable project execution.

Offsetting these increases were higher selling, general and administrative expenses of $5.4 million, largely due to additional payroll-related costs of $5.7 million, due in part to additional staffing, and increased professional services fees, offset by higher gains on the sale of non-strategic assets in Texas of $2.3 million.

2023 Compared to 2022

Our revenue increased $45.2 million in 2023, as a result of higher selling prices across all product lines providing $76.1 million of additional revenue, largely due to EDGE-related pricing initiatives.

Contracting services saw a benefit of $20.8 million from improved bid margins and favorable weather across the regions, a large concrete and asphalt paving job in the north central region and increased paving work in Texas.

Partially offsetting these increases were lower sales volumes of $33.0 million across most product lines largely as the regions continue to target improved bid margins on projects which also impacts internal sales volumes and the absence of an impact project in

South Dakota.

Also, decreased ready-mix concrete and aggregates sales due to a sale of non-strategic assets in southeast Texas in December 2022 impacted revenue.

This increase was directly related to the increased gross profit previously discussed, reduced slightly by higher selling, general and administrative expenses, primarily $1.4 million of payroll-related costs.

Our revenue decreased $16.6 million in 2024, largely due to lower pricing as a result of reduced supply input costs across our market areas.

Liquid asphalt sales volumes were up 4 percent, primarily from strong demand in California and Texas, which were partially offset by decreased volumes in the Midwest due to less carryover jobs year-over-year.

The acquisition of Albina during the fourth quarter of 2024 also contributed additional liquid asphalt sales volumes.

Our EBITDA decreased $17.9 million and EBITDA margin decreased 490 basis points in 2024.

The decrease in EBITDA was driven by reduced market pricing bringing our margins back within a normal range and an increase in operating costs, primarily $1.5 million in plant repairs at our California terminal.

Higher selling, general and administrative expenses of $735,000, largely due to higher payroll-related costs with the addition of Albina employees in the fourth quarter of 2024, also reduced EBITDA.

2023 Compared to 2022

EBITDA decreased $3.2 million and EBITDA margin decreased 450 basis points as a direct result of the decreased gross profit previously discussed.

Our revenue improved $53.9 million in 2023, largely driven by higher liquid asphalt sales volumes from additional sales opportunities across most of our primary markets, higher sales to other reportable segments and sales late in the year due to favorable weather conditions.

Higher liquid asphalt sales prices also positively impacted revenue.

We saw an increase in EBITDA of $49.8 million and EBITDA margin of 1,480 basis points in 2023.

This increase was primarily related to increased market pricing and higher sales volumes.

Partially offsetting these increases were higher operating costs for scheduled tank repair and maintenance costs and higher selling, general and administrative expenses, primarily $1.4 million of payroll-related costs.

Corporate Services and Eliminations

Corporate Services includes all expenses related to the corporate functions of our company, as well as insurance activity of our captive insurer;

interest expense on a majority of our long-term debt;

interest income;

and unrealized gains and losses on investments for the Company’s nonqualified benefit plans.

During 2023, Corporate Services contributed negative EBITDA of $53.2 million, or $24.5 million less EBITDA compared to the prior year.

The decrease was due to higher selling, general and administrative costs of $31.8 million

directly resulting from the Separation from MDU Resources.

The Company experienced increased recurring costs, including payroll-related costs of $12.3 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors;

and unrealized gains and losses on investments for our nonqualified benefit plans.

2024 Compared to 2023

Corporate Services had negative EBITDA of $60.7 million, or $7.5 million less EBITDA in 2024, compared to the prior year.

Corporate Services had increased selling, general and administrative expenses of $7.0 million.

The increase in costs for non-Separation related expenses totaled $7.4 million, which was primarily due to higher due diligence and integration costs related to corporate development and completed acquisitions of $7.5 million and higher information technology costs of $3.4 million.

information technology costs of $2.8 million;

professional services of $1.8 million;

and fees of $750,000 primarily related to fees on new debt issued in conjunction with the Separation, partially offset by a reduction in general corporate expenses from MDU Resources of $8.9 million.

We also incurred less one-time costs of $6.5 million primarily consisting of insurance costs related to the Separation and the transition services agreement with MDU Resources.

2023 Compared to 2022

Corporate Services contributed negative EBITDA of $53.2 million, or $24.5 million less EBITDA in 2023 than the prior year.

The decrease was due primarily to higher selling, general and administrative expenses of $31.8 million directly related to the Separation from MDU Resources.

In 2023, we experienced increased recurring costs, including payroll-related costs of $12.3 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors;

professional services of $2.6 million;

fees of $1.2 million, primarily related to fees on the new debt issued in conjunction with the Separation;

1 unchanged sentence

These recurring costs were offset in part by a reduction in general corporate expenses from MDU Resources of $7.6 million, as discussed in Item 8 - Note 1.

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.

Partially offsetting these increased costs were improved returns on the Company’s nonqualified benefit plan investments of $5.5 million.

During 2022, Corporate Services contributed negative EBITDA of $28.7 million, or $5.6 million less EBITDA than the prior year.

The decrease was due primarily to lower returns on the Company’s nonqualified benefit plan investments of $6.1 million.

Also, as part of the Separation, we incurred one-time costs of $10.0 million primarily related to professional services, insurance costs and the transition services agreement with MDU Resources.

Further contributing to higher selling, general and administrative costs were increased payroll-related costs due to higher incentive accruals based on our performance.

Partially offsetting these increased costs were improved returns on our nonqualified benefit plan investments of $5.5 million.

Liquidity and Capital Resources

At December 31, 2023, Knife River had unrestricted cash and cash equivalents of $219.3 million and working capital of $566.3 million.

At December 31, 2024, we had unrestricted cash and cash equivalents of $236.8 million and working capital of $617.6 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.

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 typically 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, pursuant to an indenture.

On May 31, 2023, Knife River entered into a senior secured credit agreement consisting of a $275.0 million term loan and a $350.0 million revolving credit facility, each with a SOFR-based interest rate and a maturity date of May 31, 2028.

At December 31, 2023, the Company had $697.0 million of gross debt and $329.0 million of available capacity under its revolving credit facility, net of outstanding letters of credit.

In order to borrow under the debt instruments, the Company must be in compliance with the applicable covenants and certain other conditions, all of which the Company, as applicable, was in compliance at December 31, 2023.

In the event the Company does not comply with the applicable covenants and other conditions, it would be in default on its agreements and alternative sources of funding may need to be pursued and there can be no assurance that, if needed, the Company will be able to secure additional debt or equity financing on terms acceptable to the Company or at all.

Outstanding letters of credit reduce the amount available under the revolving credit agreement.

In addition, in the first half of 2025 we expect to enter into a new senior secured Term Loan B facility of $500 million, increase the total commitments under our existing revolving credit facility from $350 million to $500 million and extend the maturity date of our existing senior secured credit facilities from 2028 to 2030.

In order to borrow under the debt instruments, we must be in compliance with the applicable covenants and certain other conditions, all of which we are in compliance at December 31, 2024.

In the event that we do not comply with the applicable covenants and other conditions, we would be in default on our agreements and alternative sources of funding may need to be pursued and there can be no assurance that, if needed, we will be able to secure additional debt or equity financing on terms acceptable to us or at all.

For additional information on our debt, see Item 8 - Note 9.

Off-Balance Sheet Arrangements

As of December 31, 2023, the Company had aggregate outstanding letters of credit issued under its revolving credit facility in the amount of $21.0 million.

Other than these letters of credit further discussed in Item 8 - Note 18, the Company does not currently have any off-balance sheet arrangements that have, or are reasonably likely to have, a material impact on current or future financial conditions, results of operations or cash flows.

As of December 31, 2024, we had aggregate outstanding letters of credit issued under our revolving credit facility in the amount of $ 20.6 million.

Other than these letters of credit further discussed in Item 8 - Note 18, we do not currently have any off-balance sheet arrangements that have, or are reasonably likely to have, a material impact on current or future financial conditions, results of operations or cash flows.

Capital Expenditures

Knife River’s capital expenditures for the year ended December 31, 2023, was $124.3 million compared to $182.0 million, including $6 million on an acquisition, for the year ended December 31, 2022.

These expenditures relate primarily to routine replacement and maintenance of vehicles and equipment;

building improvements;

aggregate reserves;

and storage facility updates.

The 2023 and 2022 capital expenditures were funded by internally generated funds and borrowings under credit facilities.

The Company expects to spend between $170 million and $180 million on capital expenditures in 2024 consisting of both maintenance and growth projects and excludes acquisitions.

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 economic conditions.

It is anticipated that all of the funds required for capital expenditures for 2024 will be funded by various sources, including internally generated funds and credit facilities.

We are committed to disciplined capital allocation, including reinvesting in our company to maintain fixed assets, improve operations and grow our business.

In 2024, we spent $170.5 million, compared to $124.3 million in 2023, on the replacement of depleting aggregate reserves, construction equipment, plant improvements and buildings.

In 2024, we spent $132.9 million on six acquisitions, which include aggregate, ready-mix and liquid asphalt operations, and initial greenfield projects.

Capital expenditures for 2024 and 2023 were funded by internally generated funds and borrowings under credit facilities.

For 2025, we have estimated capital expenditures for maintenance and improvement to be between $155 million and $215 million and approximately $522 million for the pending acquisition of Strata and organic growth projects.

Capital expenditures for future acquisitions and future organic growth opportunities would be incremental to our outlined capital program;

these opportunities are dependent upon economic and other competitive conditions.

It is anticipated that capital expenditures for 2025 will be funded by various sources, including internally generated cash and debt.

In addition to cash on hand, we intend to use a portion of the proceeds from the issuance of a new $500 million Term Loan B facility to fund the purchase of Strata.

Separately, we also intend to increase the total commitments under our existing revolving credit facility from $350 million to $500 million and extend the maturity date of our existing senior secured credit facilities from 2028 to 2030.

Net cash provided by operating activities

$ 322.3 $ 335.7 $ 207.5

Cash provided by operating activities for the year ended December 31, 2024, decreased $13.4 million, largely related to higher working capital needs.

Cash used by working capital components increased $36.1 million in 2024.

This increased usage of cash was driven largely by higher accrued compensation due in part to additional employees associated with the Separation;

higher liquid asphalt and aggregate volumes as well as higher costs of aggregate inventory;

timing of prepaid insurance due to Separation;

the removal of all related-party balances due to the Separation;

and fluctuations in the timing of payment on accounts payable.

In addition, stronger collections on receivable balances during 2024 and higher net income partially offset the decrease in cash.

Cash provided by operating activities for the year ended December 31, 2023, increased $128.2 million, largely related to increased earnings in 2023 and lower working capital needs.

Cash provided by working capital components totaled $20.2 million in 2023, compared to $29.0 million in 2022.

This decreased usage of cash was driven largely by lower payments on operating expenses at the end of the period and decreased liquid asphalt inventory balances, partially offset by increased accounts receivable balances at the end of the year associated with

higher revenues during 2023.

In addition, the timing of insurance costs associated with the captive insurer had a positive impact on cash.

Cash provided by operating activities totaled $207.5 million in 2022, compared to $181.2 million in 2021.

The increased cash provided by operating activities was largely the result of lower working capital needs.

Cash used by working capital components totaled $29.0 million in 2022, compared to $64.6 million in 2021.

This decreased usage of cash was driven largely by the timing of certain income tax payments during 2021 and the result of higher bonus depreciation related to 2021 acquisitions.

Also positively impacting working capital was higher liquid asphalt inventory balances due to higher material costs and higher deferred revenues.

Partially offsetting these increases were higher receivables balances, directly resulting from the increased revenues during 2022.

Investing activities

10 unchanged sentences

$ (294.8) $ (117.9) $ (155.9)

The increase in cash used in investing activities from 2024 to 2023 was primarily due to the completion of six acquisitions in 2024 and higher capital expenditures, including a liquid asphalt expansion project, aggregate reserve replacements and routine replacement of construction equipment.

The increase in cash usage was offset in part by additional proceeds from asset sales, largely as a result of the sale of non-strategic assets in Texas in 2024.

The decrease in cash used in investing activities from 2023 to 2022 was primarily due to a reduction in capital expenditures for the prestress facility in Washington that was completed during the third quarter of 2023, offset in part by decreased proceeds from asset sales as a result of the sale of non-strategic assets in southeast Texas in December 2022.

The decrease in cash used in investing activities from 2022 to 2021 was primarily the result of decreased cash used in acquisition activity.

Actuarial assumptions include assumptions about the discount rate and expected return on plan assets.

For 2023, the Company assumed a discount rate of 4.83 percent and long-term rate of return on its qualified defined pension plan assets of 6.50 percent.

Decreased discount rates for 2023 compared to 2022 resulted in actuarial losses, offset in part by higher than expected asset sale gains.

For 2024, we assumed a discount rate of 5.4 percent and long-term rate of return on our qualified defined pension plan assets of 6.0 percent.

Increased discount rates for 2024 compared to 2023 resulted in actuarial gains.

Differences between actuarial assumptions and actual plan results are deferred and amortized into expense when the accumulated differences exceed 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets.

Therefore, this change in asset values will be reflected in future expenses of the plans beginning in 2025.

The funded status of the plans did not change significantly with the increase in assets because the liabilities increased as well due to the decrease in the discount rate.

The Company's benefit obligations for the pension plans also saw a decline in value due to lower discount rates at the end of 2023.

At December 31, 2023, the pension plans’ accumulated benefit obligations exceeded these plans’ assets by approximately $3.2 million.

The funded status of the plans did not change significantly with the gains on the assets because the liabilities decreased as well due to the increase in the discount rate.

At December 31, 2024, the pension plans’ accumulated benefit obligations exceeded the plans’ assets by approximately $345,000.

Pretax pension expense (income) reflected in the Consolidated Statements of Operations for the years ended December 31, 2024, 2023 and 2022, was $289,000, $343,000 and $10,000, respectively.

The Company’s pension expense is currently projected to be approximately $289,000 in 2024.

The Company expects to contribute approximately $912,000 in pension plan contributions in 2024, largely resulting from the Company exhausting its prefunding credits.

During 2023, the Company contributed $1.2 million to its pension plans.

Critical Accounting Estimates

Knife River has prepared its financial statements in conformity with GAAP.

The preparation of its financial statements requires management 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 financial statements, as well as the reported amounts of revenues and expenses during the reporting period.

We have prepared our financial statements in conformity with GAAP.

The preparation of our financial statements requires management 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 financial statements, as well as the reported amounts of revenues and expenses during the reporting period.

Management reviews these estimates and assumptions based on historical experience, changes in business conditions and other relevant factors believed to be reasonable under the circumstances.

Critical accounting estimates are defined as estimates that require management to make assumptions about matters that are uncertain at the time the estimate was made, and changes in the estimates could have a material impact on Knife River’s financial position or results of operations.

Knife River’s critical accounting estimates are subject to judgments and uncertainties that affect the application of its significant accounting policies discussed in Item.

Our critical accounting estimates are subject to judgments and uncertainties that affect the application of the significant accounting policies discussed in Item.

As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised.

Consequently, Knife River’s financial position or results of operations may be materially different when reported under different conditions or when using different assumptions in the application of the following critical accounting estimates.

Consequently, our financial position or results of operations may be materially different when reported under different conditions or when using different assumptions in the application of the following critical accounting estimates.

Revenue Recognition

Revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

The recognition of revenue requires Knife River to make estimates and assumptions that affect the reported amounts of revenue.

The accuracy of revenues reported on the audited consolidated financial statements depends on, among other things, management’s estimates of total costs to complete projects because Knife River uses the cost-to-cost measure of progress on contracting services contracts for revenue recognition.

To determine the proper revenue recognition method for contracts, Knife River evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation.

For most contracts, the customer contracts with Knife River to provide a significant service of integrating a complex set of tasks and components into a single project.

Hence, Knife River’s contracts are generally accounted for as one performance obligation.

Knife River recognizes contracting services revenue over time using an input method based on the cost-to-cost measure of progress for contracts because it best depicts the transfer of assets to the customer which occurs as Knife River incurs costs on the contract.

Since contract prices are generally set before the work is performed, the estimates pertaining to every project could contain significant unknown risks such as volatile labor, material and fuel costs, weather delays, adverse project site conditions, unforeseen actions by regulatory agencies, performance by subcontractors, job management and relations with project owners.

Changes in estimates could have a material effect on Knife River’s results of operations, financial position and cash flows.

For the years ended December 31, 2023, 2022 and 2021, Knife River’s total contracting services revenue was $1.3 billion, $1.2 billion and $1.0 billion, respectively.

Contracts are often modified to account for changes in contract specifications and requirements.

Knife River considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations.

We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations.

Generally, contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration of services provided in the context of the contract and are accounted for as if they were part of that existing contract.

The effect of a contract modification on the transaction price and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis.

Knife River’s contracts for contracting services generally contain variable consideration including liquidated damages, performance bonuses or incentives, claims, unpriced change orders and penalties or index pricing.

Our contracts for contracting services generally contain variable consideration including liquidated damages, performance bonuses or incentives, claims, unpriced change orders and penalties or index pricing.

The variable amounts usually arise upon achievement of certain performance metrics or change in project scope.

Knife River estimates the amount of revenue to be recognized on variable consideration using one of the two prescribed estimation methods, the expected value method or the most likely amount method, depending on which method best predicts the most likely amount of consideration Knife River expects to be entitled to or expects to incur.

We estimate the amount of revenue to be recognized on variable consideration using one of the two prescribed estimation methods, the expected value method or the most likely amount method, depending on which method best predicts the most likely amount of consideration we expect to be entitled to or expect to incur.

Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period, using estimates of variable consideration and assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management.

Knife River only includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved.

We only include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved.

Changes in circumstances could impact management’s estimates made in determining the value of variable consideration recorded.

When determining if the variable consideration is constrained, Knife River considers if factors exist that could increase the likelihood or the magnitude of a potential reversal of revenue.

Knife River updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis.

Knife River believes its estimates surrounding the cost-to-cost method are reasonable based on the information that is known when the estimates are made.

Knife River has contract administration, accounting and management control systems in place that allow its estimates to be updated and monitored on a regular basis.

Business Combinations

We account for acquisitions on the audited consolidated financial statements starting from the date of the acquisition, which is the date that control is obtained.

The acquisition method of accounting requires acquired assets and liabilities assumed be recorded at their respective fair values as of the date of the acquisition.

The excess of the purchase price over the fair value of the assets acquired and liabilities assumed is recorded as goodwill.

The estimation of fair values of acquired assets and liabilities assumed requires significant judgment and various assumptions.

Although independent appraisals may be used to assist in the determination of the fair value of certain assets and liabilities, the appraised values may be based on significant estimates provided by management.

The amounts and useful lives assigned to depreciable and amortizable assets compared to amounts assigned to goodwill, which is not amortized, can affect the results of operations in the period of and periods subsequent to a business combination.

In determining fair values of acquired assets and liabilities assumed, we use various observable inputs for similar assets or liabilities in active markets and various unobservable inputs, which includes the use of valuation models.

Fair values are based on various factors including, but not limited to, age and condition of property, maintenance records, auction values for equipment with similar characteristics, recent sales and listings of comparable properties, data collected from drill holes and other subsurface investigations and geologic data.

We primarily use the market and cost approaches in determining the fair value of land and property, plant and equipment.

A combination of the market and income approaches are used for aggregate reserves and intangibles, primarily a discounted cash flow model.

Although we may engage independent third-party consultants to assist with

the valuation of aggregate reserves and intangibles, the valuations are based on significant estimates that are approved by management.

The process is highly subjective and requires a large degree of management judgement.

Assumptions used may vary for each specific business combination due to unique circumstances of each transaction.

Assumptions may include discount rate, time period, terminal value and growth rate.

The values generated from the discounted cash flow model are sensitive to the assumptions used.

Inaccurate assumptions can lead to deviations from the values generated.

There is a measurement period after the acquisition date during which we may adjust the amounts recognized for a business combination.

Any such adjustments are recorded in the period the adjustment is determined with the corresponding offset to goodwill.

These adjustments are typically based on obtaining additional information that existed at the acquisition date regarding the assets acquired and the liabilities assumed.

The measurement period ends once we have obtained all necessary information that existed as of the acquisition date, but does not extend beyond one year from the date of the acquisition.

Once the measurement period has ended, any adjustments to assets acquired or liabilities assumed are recorded in income from continuing operations.

We perform our goodwill impairment testing annually in the fourth quarter.

In addition, the test is performed on an interim basis whenever events or circumstances indicate that the carrying amount of goodwill may not be recoverable.

Examples of such events or circumstances may include a significant adverse change in business climate, weakness in an industry in which Knife River’s reporting units operate or recent significant cash or operating losses with expectations that those losses will continue.

Knife River has determined that the reporting units for its goodwill impairment test are its operating segments as they constitute a business for which discrete financial information is available and for which segment management regularly reviews the operating results.

Examples of such events or circumstances may include a significant adverse change in business climate, weakness in an industry in which our reporting units operate or recent significant cash or operating losses with expectations that those losses will continue.

We have determined that the reporting units for our goodwill impairment test are our operating segments as they constitute a business for which discrete financial information is available and for which segment management regularly reviews the operating results.

Goodwill impairment, if any, is measured by comparing the fair value of each reporting unit to its carrying value.

If the fair value of a reporting unit exceeds its carrying value, the goodwill of the reporting unit is not impaired.

If the carrying value of a reporting unit exceeds its fair value, Knife River must record an impairment loss for the amount that the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit.

If the carrying value of a reporting unit exceeds its fair value, we must record an impairment loss for the amount that the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit.

For the years ended December 31, 2024, 2023 and 2022, there were no impairment losses recorded.

At October 31, 2023, the fair value of each of Knife River’s reporting units substantially exceeded the carrying value.

Determining the fair value of a reporting unit requires judgment and the use of significant estimates, which include assumptions about Knife River’s future revenue, profitability and cash flows, long-term growth rates,

amount and timing of estimated capital expenditures, inflation rates, weighted average cost of capital, operational plans, and current and future economic conditions, among others.

The fair value of each reporting unit is determined using a weighted combination of income and market approaches.

Knife River believes that the estimates and assumptions used in its impairment assessments are reasonable and based on available market information.

Knife River uses a discounted cash flow methodology for its income approach.

We believe the estimates and assumptions used in our impairment assessments are reasonable and based on available market information.

A discounted cash flow methodology is used for our income approach.

Under the income approach, the discounted cash flow model determines fair value based on the present value of projected cash flows over a specified period and a residual value related to future cash flows beyond the projection period.

Both values are discounted using a rate that reflects the best estimate of the weighted average cost of capital for the Company.

Under the market approach, Knife River estimates fair value using various multiples derived from enterprise value to EBITDA for comparative peer companies as well as comparable market transaction multiples to EBITDA for each respective reporting unit.

Both values are discounted using a rate that reflects the best estimate of our weighted average cost of capital.

Under the market approach, we estimate fair value using various multiples derived from enterprise value to EBITDA for comparative peer companies as well as comparable market transaction multiples to EBITDA for each respective reporting unit.

These multiples are applied to operating data for each reporting unit to arrive at an indication of fair value.

In addition, Knife River adds a reasonable control premium when calculating the fair value utilizing the peer multiples, which is estimated as the premium that would be received in a sale in an orderly transaction between market participants.

Knife River uses significant judgment in estimating its five-year forecast.

The assumptions underlying cash flow projections are in sync as applicable with Knife River’s strategy and assumptions.

If impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value of the assets and recording a loss if the carrying value is greater than the fair value.

During the year ended December 31, 2023, the Company performed impairment testing on assets where triggering events were identified due to recent operating results or changes in plans with the asset groups.

The undiscounted cash flows on an asset group with a net asset book value of $65 million indicated it was recoverable and not impaired.

However, the Company did recognize non-cash asset impairments of $5.8 million as a result of certain other aggregate sites no longer being economically feasible to mine and having no remaining value.

No impairment losses were recorded in 2024 or 2022.

During the year ended December 31, 2023, we recognized non-cash asset impairments of $5.8 million as a result of certain aggregate sites no longer being economically feasible to mine and having no remaining value.
