Knife River Corporation (KNF) Risk Analysis

Disputes may arise between the Company and MDU Resources in a number of areas relating to the various transaction agreements, including: labor, tax, employee benefit, indemnification and other matters arising from the Company's Separation from MDU Resources; employee retention and recruiting; business combinations involving the Company; and the nature, quality and pricing of services that Knife River and MDU Resources have agreed to provide each other. The Company may not be able to resolve potential conflicts, and even if it does, the resolution may be less favorable than if it were dealing with an unaffiliated party.

Changes to federal, state and local tax laws have the ability to benefit or adversely affect Knife River's earnings and customer costs. Significant changes to corporate tax rates could result in the impairment of deferred tax assets that are established based on existing law at the time of deferral. A number of factors may increase Knife River's future effective income tax rate, including; governmental authorities increasing taxes or eliminating deductions, particularly the depletion deduction, the mix of earnings from depletable versus non-depletable businesses, the jurisdictions in which earnings and/or revenues are taxed, the resolution of issues arising from tax audits with various tax authorities, changes in the valuation of our deferred tax assets and liabilities, adjustments to estimated taxes upon finalization of various tax returns, changes in available tax credits, changes in stock-based compensation, other changes in tax laws and the interpretation of tax laws and/or administrative practices.

Knife River is subject to environmental laws and regulations affecting many aspects of its operations, including air and water quality, wastewater discharge, the generation, transportation and disposal of solid waste and hazardous substances, aggregate permitting and other environmental considerations. These laws and regulations can increase capital, operating and other costs; cause delays as a result of litigation and administrative proceedings; and create environmental compliance, remediation, containment, monitoring and reporting obligations for construction materials facilities. Environmental laws and regulations can also require the Company to install pollution control equipment at its facilities, clean up spills and other contamination, and correct environmental hazards, including payment of all or part of the cost to remediate sites where Knife River's past activities, or the activities of other parties, caused environmental contamination. These laws and regulations generally require Knife River to obtain and comply with a variety of environmental licenses, permits, inspections and other approvals. Although the Company strives to comply with all applicable environmental laws and regulations, public and private entities and private individuals may interpret Knife River's legal or regulatory requirements differently and seek injunctive relief or other remedies against Knife River. The Company cannot predict the outcome, financial or operational, of any such litigation or administrative proceedings. Existing environmental laws and regulations may be revised and new laws and regulations seeking to protect the environment may be adopted or become applicable to Knife River. These laws and regulations could require the Company to limit the use or output of certain facilities; restrict the use of certain fuels; prohibit or restrict new or existing services; replace certain fuels with renewable fuels; retire and replace certain facilities and equipment; install pollution controls; remediate environmental impacts; remove or reduce environmental hazards; or forego or limit the development of resources. Revised or new laws and regulations that increase compliance and disclosure costs and/or restrict operations could adversely affect Knife River's results of operations and cash flows.

Knife River has defined benefit pension plans for some of its current and former employees. Assumptions regarding future costs, returns on investments, interest rates and other actuarial assumptions have a significant impact on the funding requirements and expense recorded relating to these plans. Adverse changes in economic indicators, such as consumer spending, inflation data, interest rate changes, political developments and threats of terrorism, among other things, can create volatility in the financial markets. These changes could impact the assumptions and negatively affect the value of assets held in Knife River's pension plans and may increase the amount and accelerate the timing of required funding contributions for those plans.

Knife River participates in MEPPs for employees represented by certain unions. Knife River is required to make contributions to these plans in amounts established under numerous collective bargaining agreements between the operating subsidiaries and those unions. Knife River may be obligated to increase its contributions to underfunded plans that are classified as being in endangered, seriously endangered or critical status as defined by the Pension Protection Act of 2006. Plans classified as being in one of these statuses are required to adopt Rehabilitation Plans or Funding Improvement Plans to improve their funded status through increased contributions, reduced benefits or a combination of the two. Knife River may also be required to increase its contributions to MEPPs if the other participating employers in such plans withdraw from the plans and are not able to contribute amounts sufficient to fund the unfunded liabilities associated with their participation in the plans. The amount and timing of any increase in its required contributions to MEPPs may depend upon one or more factors, including the outcome of collective bargaining; actions taken by trustees who manage the plans; actions taken by the plans' other participating employers; the industry for which contributions are made; future determinations that additional plans reach endangered, seriously endangered or critical status; newly enacted government laws or regulations and the actual return on assets held in the plans; among others. Knife River could experience increased operating expenses as a result of required contributions to MEPPs, which could have an adverse effect on its results of operations, financial position or cash flows. In addition, pursuant to the Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act, the Company could incur a partial or complete withdrawal liability upon withdrawing from a plan, exiting a market in which it does business with a union workforce or upon termination of a plan. Knife River could also incur additional withdrawal liability if its withdrawal from a plan is determined by that plan to be part of a mass withdrawal.

A majority of Knife River's business is seasonal, with results of operations affected by weather conditions. Construction materials production and related contracting services typically follow the activity in the construction industry, with heavier contracting services workloads in the spring, summer and fall. Extreme or unusually adverse weather conditions, which have occurred and may reoccur, such as extreme temperatures, heavy or sustained rainfall or snowfall, wildfires and storms may affect the demand for products and the ability to perform services on construction work. The Company could also be impacted by drought conditions, which may restrict the availability of water supplies and inhibit the ability to conduct operations. As a result, extreme or unusually adverse weather conditions could negatively affect the Company's results of operations, financial position and cash flows.

Knife River uses technology in substantially all aspects of its business operations and requires uninterrupted operation of information technology and operation technology systems, including disaster recovery and backup systems and network infrastructure. While Knife River has policies, procedures and processes in place designed to strengthen and protect these systems, they may be vulnerable to physical and cybersecurity failures or unauthorized access, due to: hacking, human error, theft, sabotage, malicious software, ransomware, third-party compromise, acts of terrorism, acts of war, acts of nature or other causes. Although there are manual processes in place, should a compromise or system failure occur, interdependencies to technology may disrupt Knife River's ability to fulfill critical business functions. This may include interruption of facilities for delivery of construction materials or other products and services, any of which could adversely affect its reputation, business, cash flows and results of operations or subject Knife River to legal costs. Knife River's accounting systems and its ability to collect information and invoice customers for products and services could be disrupted. If Knife River's operations are disrupted, it could result in decreased revenues and remediation costs that could adversely affect Knife River's results of operations and cash flows. Knife River, through the ordinary course of business, requires access to sensitive customer, supplier, employee, financial and other data. While Knife River has implemented extensive security measures, including limiting the amount of sensitive information retained, a breach of its systems could compromise sensitive data and could go unnoticed for some time. Such an event could result in negative publicity and reputational harm, remediation costs, legal claims and fines that could have an adverse effect on its financial results. Third-party service providers that perform critical business functions for Knife River or have access to sensitive information within Knife River also may be vulnerable to security breaches and information technology risks that could adversely affect the Company. Cyberattacks continue to increase in frequency and sophistication, which could cause Knife River's information systems to be a target of ongoing and sophisticated cyberattacks by a variety of sources with the apparent aim to breach its cyber-defenses. Also, Knife River may face increased cyber risk due to the increased use of employee-owned devices and work from home arrangements. Such incidents could have a material adverse effect on its business, financial condition or results of operations. Management is continuously reevaluating the need to upgrade and/or replace systems and network infrastructure. These upgrades and/or replacements could adversely impact operations by imposing substantial capital expenditures, creating delays or outages, or creating difficulties transitioning to new systems. System disruptions, if not anticipated and appropriately mitigated, could adversely affect the Company. The SEC has adopted new rules that require Knife River to provide greater disclosures around cybersecurity risk management, strategy and governance, as well as to disclose the occurrence of material cybersecurity incidents. Knife River cannot predict or estimate the amount of additional costs it will incur in order to comply with these rules or the timing of such costs. These rules and regulations may also require Knife River to report a cybersecurity incident before it has been able to fully assess the impact or remediate the underlying issue. Efforts to comply with such reporting requirements could divert management's attention from its incident response and could potentially reveal system vulnerabilities to threat actors. Failure to timely report incidents under these or other similar rules could also result in monetary fines, sanctions, or subject Knife River to other forms of liability. This regulatory environment is increasingly challenging and may present material obligations and risks to Knife River's business, including significantly expanded compliance burdens, costs and enforcement risks. The Company has not incorporated artificial intelligence within its operations but does have technology partners that have incorporated artificial intelligence into their systems. The potential use of artificial intelligence could introduce security risks that could expose confidential data leading to the loss of competitive and reputational damage. The implementation of artificial intelligence could also impose a reliability risk of the Company's data not being fully vetted for accuracy. While Knife River's insurance policies include liability coverage for certain of these matters, if it experiences a significant security incident, it could be subject to liability or other damages that exceed its insurance coverage and it cannot be certain that such insurance policies will continue to be available to it on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against Knife River that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on its results of operations, financial condition and cash flows.

Prior to the Separation, Knife River and MDU Resources entered into a separation and distribution agreement and also entered into various other agreements, including a transition services agreement, a tax matters agreement and an employee matters agreement. The separation agreement, the tax matters agreement and the employee matters agreement determine the allocation of assets and liabilities between the companies following the Separation for those respective areas and include any necessary indemnifications related to liabilities and obligations. The transition services agreement provides for the performance of certain services by MDU Resources for the benefit of Knife River, or in some cases certain services provided by Knife River for the benefit of MDU Resources, for a limited period of time after the Separation. Knife River will rely on MDU Resources to satisfy its obligations under these agreements. If MDU Resources is unable to satisfy its obligations under these agreements, including its indemnification obligations, Knife River could incur operational difficulties or losses. If Knife River does not have agreements with other providers of these services once certain transaction agreements expire or terminate, Knife River may not be able to operate its business effectively, which may have a material adverse effect on its financial position, results of operations and cash flows.
