Fellow Stockholders:


I invite you to join me,attend our Board of Directors and members of our senior management team at our annual stockholder meeting at 11 a.m., Central Daylight Saving Time, on CDT May 8, 2018,9, 2023, at 909 Airport Road in Bismarck, North Dakota.

In additionDakota, where you will have the opportunity to the business we will conductengage with our Board of Directors and senior management team. Please check our website at the meeting, I will describe the significant drivers of our strong 2017 financial results as well as the growth projects we have underway or soon to be started this year. Absent the benefit we recorded in 2017 from implementing the Tax Cuts and Jobs Act, which was signed into law December 22, our earnings were up about 5 percent over 2016. This shows the strength of our two-pillar approach to our operations, with strong performance from both our regulated energy delivery businesses and our construction materials and services businesses.

We remain committed to returning the value to you that you expect from your investment in MDU Resources. In 2017, we marked our 80th consecutive year of paying dividends to our stockholders and we increased our dividend paymentwww.mduproxy.com for the 27th consecutive year, a feat achieved by fewer than 100 other U.S.-listed companies.

As we celebrate our 70th year of being listed on the New York Stock Exchange, we remain committed to Building a Strong America®. We hope you share in our excitement about the momentum we have going into 2018 and the substantial opportunities for growth at all of our businesses.

In our Proxy Statement this year, we have included additional summarized information about our environmentalmeeting.

We had very strong operational performance in 2022. I look forward to sharing with you our results as well as the strong growth trajectory we believe we are on at each of our businesses, with an all-time high combined backlog of more than $3 billion of work at our construction businesses and planned capital investments of $2.5 billion over the next five years at our regulated energy delivery businesses.

I will give an update on the great progress we’re making toward completing the anticipated separation of Knife River Corporation into an independent, publicly traded company and the strategic review of MDU Construction Services Group, Inc. We expect both initiatives to be complete in the second quarter as we work to optimize value for you, our shareholders, by working to create two pure-play, publicly traded companies, with one focused on regulated energy delivery and the other on construction materials.

Business Performance Highlights
Future Structure of MDU Resources
The company’s board of directors has determined the future company structure that is most likely to maximize long-term value for stockholders is to create two pure-play publicly traded companies, one focused on regulated energy delivery and the other on construction materials. To achieve this future structure, the company is working toward a separation of Knife River Corporation to create a standalone leading construction materials company, and it is evaluating options to optimize the value of its construction services business, with the review expected to be complete in the second quarter of 2023.
In addition to pursuing each of these strategic initiatives, all of our business segments performed well despite inflationary pressures and supply chain challenges throughout 2022.
Regulated Energy Delivery
Continued Growth with New Customers. Over 18,000 new customers were connected to our utilities system, representing customer growth of 1.6%.
Investing in Electric Generation. The electric segment continues to make progress toward reducing its greenhouse gas emissions. In 2022, operations were ceased at the company’s last wholly owned coal-fired electric generating facility, Heskett Station Units 1 and 2 in Mandan, North Dakota. Construction of Heskett Station Unit 4, an 88-megawatt natural-gas fired simple-cycle combustion turbine, is expected to be complete in the summer of 2023.
Joint Regional Transmission Line Project.The electric segment and Otter Tail Power Company announced another Midcontinent Independent System Operator-approved joint regional transmission line project. Together, the companies plan to develop, construct and co-own a 95-mile, 345-kilovolt transmission line that would span from Jamestown to Ellendale in North Dakota. We expect the project to create a more resilient regional transmission grid, helping to ensure reliable and affordable electric service to our customers.
Natural Gas Pipeline Expansion. The pipeline segment put the North Bakken Expansion project into service on February 1, 2022 and has announced other significant growth projects in various stages and pending regulatory approvals, including the 2023 Line Section 27 Expansion project in northwestern North Dakota expecting to add natural gas transportation capacity of 175 million cubic feet per day; Grasslands South Expansion from western North Dakota to northern Wyoming, which is expected to add natural gas transportation capacity of 94 million cubic feet per day; and Line Section 15 Expansion in western South Dakota, which is expected to add natural gas transportation capacity of 25 million cubic feet per day.
Construction Materials & Services
Record Revenues. The construction materials segment had record revenues of $2.53 billion in 2022 and earnings of $116.2 million, compared to revenues of $2.23 billion and earnings of $129.8 million in 2021. Demand remained strong for construction materials and contracting work as evidenced by a record backlog at December 31, 2022 of $935 million, up 32% compared to $708 million at December 31, 2021.
Growth Opportunities.The construction materials and contracting segment continued its growth through acquisitions in 2022. Allied Concrete and Supply Co., a producer of ready-mixed concrete in California, was acquired in December 2022. In addition to pursuing additional acquisitions, the segment expects ongoing growth opportunities, including through projects that result from the U.S. Infrastructure Investment and Jobs Act that provides approximately $650 billion of reauthorized funds for the Department of Transportation surface transportation program and $550 billion of new infrastructure funds.
Record Revenues. The construction services segment earned record revenues of $124.8 million in 2022, compared to $109.4 million in 2021. Revenues were a record $2.70 billion, compared to $2.05 billion in 2021. Demand continues to be extremely strong for construction services work, with the construction services having a record backlog of $2.13 billion at December 31, 2022, up, 54% compared to $1.38 billion at December 31, 2021.
Renewable Electric Generation Project.The construction services segment continues to emphasize its premier services for renewable electric generation projects. The construction services segment subsidiary completed construction in October 2022 on a 200-megawatt solar facility in Moapa, Nevada, installing 621,093 solar modules, as well as ancillary facilities for the project.

Business Performance Highlights
Our overall performance in 2017 was consistent with our long-term strategy as we focused on our regulated energy delivery and construction materials and services business segments. In addition to our 2017 financial performance highlighted on the next page, we accomplished:
The sale of our interest in the Pronghorn natural gas processing plant in January 2017 which reduced the company’s risk by decreasing its exposure to commodity price fluctuations.
Our construction services segment had record revenues of $1.37 billion and its backlog at December 31, 2017 was $708 million, 49% higher than 2016.
Our construction materials and contracting segment had higher aggregate sales volumes on strong commercial and residential demand in certain regions. Its backlog at year-end of $486 million, while lower than 2016, is the third largest year-end level for this segment. The segment continues to strategically manage its nearly 1.0 billion tons of aggregate reserves.
We received advance determination of prudence from the North Dakota Public Service Commission to purchase an expansion of the Thunder Spirit wind farm.
The pipeline and midstream segment had record transportation volumes in 2017.
Our pipeline and midstream segment secured sufficient capacity commitments to expand its Line Section 27 natural gas transportation system in the Bakken producing area of northwestern North Dakota. The project will involve the construction of approximately 13 miles of pipeline and associated facilities. The expansion will provide WBI Energy, Inc.’s Line Section 27 pipeline with capacity for over 600,000 dekatherms per day. The targeted in-service date for the project is fall 2018.
Our pipeline and midstream segment continued permitting, surveying, and acquisition activity for a 38-mile natural gas transmission pipeline to deliver natural gas to eastern North Dakota and far western Minnesota. Following receipt of necessary regulatory approvals and easement acquisition, construction is expected to start and be completed in 2018.
The board of directors authorized management to evaluate and pursue a holding company reorganization which is intended to provide further separation between the company’s regulated and unregulated businesses and additional financing flexibility as all of the company’s utility operations will be conducted through wholly-owned subsidiaries. The reorganization, which is expected to be effective January 1, 2019, is subject to approval by the Federal Energy Regulatory Commission and various state regulatory commissions.
With our accomplishments in 2017, we are optimistic about the company’s future financial performance. The chart below shows our progress over the last five years.

Environmental Stewardship
Carbon Footprint. While we have reported carbon emissions from our electric generating fleet for many years, as of January 1, 2022, we began tracking our Scope 1 and Scope 2 carbon emissions across the company to establish our corporatewide baseline of emissions. For more information on anticipated future reporting and emission reduction goals, see our Sustainability Report.
Retirement of Coal Facilities. We have ceased operating all wholly owned coal-fired generation facilities, with Units 1 and 2 at Heskett Station near Mandan, North Dakota, being retired in early 2022 as more economical options exist to supply energy for our customers. These retirements will further reduce our greenhouse gas emissions intensity as we progress toward our reduction target of 45% by 2030, compared to 2005 levels, from owned generating facilities. During 2022, Montana-Dakota Utilities Co. began construction of a new 88-MW simple-cycle natural gas-fired combustion peaking turbine unit at the existing Heskett Station.
MDU Resources Group, Inc. Proxy Statement 10

Generation Capacity by Fuel Type. Montana-Dakota Utilities Co.’s historical and year-end 2022 total generating capacity by fuel type shows the shift from coal to more renewable resources as follows:
mdu-20230323_g26.jpg
    Methane Emissions. We have established a near-term methane emissions intensity reduction target of 25% by 2030, compared to our 2020 rate, at our natural gas pipeline business. In addition WBI Energy, Inc. joined the One Nation’s Energy Future Coalition (ONE Future Coalition) in 2022. The ONE Future Coalition is a group of more than 55 natural gas companies working together to voluntarily reduce methane emissions across the natural gas value chain to 1% or less by 2025. It is comprised of some of the largest natural gas production, gathering and boosting, processing, transmission and storage, and distribution companies in the U.S.
    Climate Scenario Analysis. The company completed a climate scenario analysis in 2021 for its electric generation operations following guidance from the TCFD.
Climate-Related Risks and Opportunities. In 2022, according to TCFD guidance, our businesses enhanced their understanding and identification of our climate-related risks and opportunities over the short, medium and long term. This exercise helps us strategically prepare to mitigate potential risks and optimize opportunities. Examples of some of the key items identified include:
Both risks and opportunities from increased frequency and duration of severe weather events. For instance, property and facility damage is a risk that can result from inclement weather. Weather-related damage also presents an opportunity, however, as our construction businesses can provide infrastructure repair and reconstruction services.
Both risks and opportunities from efforts to decarbonize electric generation sources. This requires investment in, partnership with, and construction of renewable energy sources, such as wind and solar generation and biogas producers. It is also expected that natural gas will be needed as a backup generation fuel source for periods when renewable sources are unavailable.
Changes in public policy to address climate change could create risks and opportunities as demand for the company’s products and services could be impacted, costs could escalate, and modifications and additional investment in our regulated energy delivery business may be necessary to ensure reliability of service to customers.
We intend to include our full risks and opportunities assessment in the company’s 2022 Sustainability Report, which is expected to be available in the third quarter of 2023.

Intermountain Gas Company received the 2022 ENERGY STAR® Market Leader Award for its efforts to promote energy-efficient residential construction and help homebuyers and residents experience the quality, comfort, and value that come with living in an ENERGY STAR-certified home or apartment.
■    Renewable Diesel. In 2021, a number of Knife River Corporation’s west coast operations used renewable diesel fuel in their on-road and off-road fleets. Engine performance, engine maintenance, and fuel efficiency results were positive during the pilot, and Knife River Corporation is beginning to utilize renewable diesel in more locations where feasible. In Oregon, Knife River Corporation has successfully piloted the use of renewable diesel fuel in its on-road and off-road fleet vehicles, reducing GHG emissions and improving fuel efficiency, and expects that greater than 90% of its 2023 diesel consumption in Oregon (and approximately 18% of its company-wide diesel consumption) will be renewable diesel.

■    Environmental-Related Investments. Knife River Corporation has invested in Blue Planet Systems Corporation to pursue the use of synthetic aggregates in ready-mix concrete. Blue Planet Systems Corporation is testing methods of creating synthetic limestone by using carbon dioxide captured from existing sources. The synthetic limestone could then be used as a component of concrete. In addition to sequestering carbon dioxide through this process, the use of synthetic limestone could also prolong the life of natural aggregate sources.
■    Warm-Mix Asphalt. Knife River Corporation produces and places warm-mix asphalt in applications where warm-mix asphalt is allowed. Warm-mix asphalt is produced at cooler temperatures than traditional hot-mix asphalt methods, which reduces the amount of fuel needed in the production process, thereby reducing emissions and fumes.
Recycling. Knife River Corporation continues its long-standing practice of recycling and reusing building materials. Recycling conserves natural resources, uses less energy, reduces waste disposal at local landfills, and ultimately costs less for our customers. Knife River Corporation recycles or reuses asphalt pavement, pre-consumer asphalt shingles, refined fuel oil, demolition concrete, returned concrete at ready-mix plants, fly ash, slag, silica fume and other cement-replacement materials, and dimension stone reject material.
    Energy Efficiency. Our utility companies actively pursue programs to increase energy efficiency and conservation for electric and natural gas customers. This includes partnering with local community action agencies in providing low-income assistance for utility customers and offering residential and commercial incentive programs that promote installation of energy-efficient electric and natural gas equipment.
    Renewable Natural Gas. Our utility companies are pursuing additional opportunities to provide renewable natural gas to customers. We have produced renewable natural gas from the Billings, Montana, landfill for customer use since 2010. In Idaho, three dairy digesters have been adding renewable natural gas to our system for customer use since 2020.

MDU Resources remains committed to maintaining the trust of these stakeholders by operating with integrity and being a good corporate citizen. Below are highlights of our social responsibility programs relating to our employees, stockholders, communities, and customers.
    Our Employees and Human Capital Management. At the core of Building a Strong America® is building a strong workforce. At MDU Resources, this means building a strong team of employees with a focus on integrity and safety and a commitment to diversity, equity, and inclusion. Our team included 14,929 employees located in 44 states plus Washington D.C. as of December 31, 2022. Our number of employees peaked in the third quarter at just over 16,800. Our Employer Information Report EEO-1 is available on our website at www.mdu.com/careers. The information on our website is not part of this Proxy Statement and is not incorporated by reference into this Proxy Statement.
Diversity, Equity, and Inclusion. MDU Resources is committed to an inclusive environment that respects the differences and embraces the strengths of our diverse employees. Essential to the company’s success is its ability to attract, retain, and engage the best people from a broad range of backgrounds and build an inclusive culture where all employees feel valued and contribute their best. To aid in the company’s commitment to an inclusive environment, each business segment has a diversity officer who serves as a conduit for diversity-related issues and provides a voice for all employees. The company requires employees to participate in training on the company’s code of conduct and additional courses focusing on diversity, effective leadership, equal employment opportunity, workplace harassment, respect, and unconscious bias. The company has three strategic goals related to diversity:
mdu-20230323_g28.jpg

CEO Action for Diversity and Inclusion Pledge.In March 2022, MDU Resources’ chief executive officer signed the CEO Action for Diversity and Inclusion Pledge, joining more than 2,000 chief executive officers in signing and committing to four goals to be a catalyst for further conversations and action around diversity and inclusion in the workplace. The four goals include:
Cultivating environments that support open dialogue on complex and often-difficult conversations.
Implementing and expanding unconscious bias education and training.
Sharing best-practice diversity, equity and inclusion programs and initiatives.
Engaging boards of directors when developing and evaluating diversity, equity and inclusion strategies.
Executive Compensation and Diversity, Equity, and Inclusion. In February 2022, the board of directors approved a performance modifier for the 2022 annual incentive award program for executive officers based upon the company’s achievement of certain measures to attract, retain, and develop a diverse and inclusive workforce. The DEI modifier includes a focus on representation of diverse employees in executive succession plans, outreach efforts to attract diverse candidates for open positions at the company, implementing enhanced diversity, equity, and inclusion training and mentoring for new employees, and development of enhanced employee data dashboards to further support the company’s efforts to attract, retain, and develop a diverse and inclusive workforce. For more information on the DEI modifier and the results for 2022, please refer to the “2022 Compensation for Our Named Executive Officers” section in the “Compensation Discussion and Analysis.”
Building People. Building a strong workforce begins with employee recruitment. The company uses a variety of means to recruit new employees for open positions, including posting on the company’s website, employee referrals, union workforce, direct recruitment, advertising, social media, career fairs, partnerships with colleges and technical schools, job service organizations, and associations connected with a variety of professions. The company also utilizes internship programs to introduce individuals to the company’s business operations and provide a possible source of future employees. Building a strong workforce also requires developing employees in their current positions and for future advancement. The company provides opportunities for advancement through job mobility, succession planning, and promotions both within and between business segments. The company provides employees the opportunity to further develop and grow through various forms of training, mentorship programs, and internship programs.

Knife River Training Center. While labor challenges continue to impact many construction companies, Knife River Corporation is actively engaged in attracting, training and retaining the next generation of construction-industry employees. In February 2022, the company completed a state-of-the-art training center on a 230-acre tract of property in the Pacific Northwest, featuring an 80,000 square-foot heated indoor arena for training on trucks and heavy equipment and an attached 16,000 square-foot classroom and conference room facility. The center is used company-wide to enhance the skills of current employees and to recruit and teach skills to new employees through both classroom education and hands-on experience. It also is used by Knife River Corporation’s customers and industry peers, who send employees to the center to take courses on heavy equipment, truck driving, leadership development, facilitator training, safety training and more.
In 2022, the center hosted approximately 4,500 individuals for various trainings, classes, meetings and events. The facility plays a critical role in Knife River Corporation’s workforce remaining sustainable and contributes to showcasing construction as a career of choice.
Knife River Corporation’s outreach efforts to market the training center have included interfacing with historically underrepresented groups, and the company has partnered with the National Association of Minority Contractors to provide scholarships for training to qualifying employees of minority-owned businesses.
mdu-20230323_g18.jpg
The Knife River Corporation training center received the 2022 Risk Management Excellence Award presented by Liberty Mutual Insurance Company. The award recognizes outstanding employee health and safety achievement related to an industry-leading, state-of-the-art training center leading to better training and lowering risks to the employees and general public. Liberty Mutual Insurance Company has granted this award less than 20 times in their 100-year history.

Additional Information - Majority Voting
A majority of votes cast is required to elect a director in an uncontested election. A majority of votes cast means the number of votes cast “for” a director’s election must exceed the number of votes cast “against” the director’s election. “Abstentions” and “broker non-votes” do not count as votes cast “for” or “against” the director’s election. In a contested election, which is an election in which the number of nominees for director exceeds the number of directors to be elected and which we do not anticipate, directors will be elected by a plurality of the votes cast.
Unless you specify otherwise when you submit your proxy, the proxies will vote your shares of common stock “for” all directors nominated by the board of directors. If a nominee becomes unavailable for any reason or if a vacancy should occur before the election, which we do not anticipate, the proxies will vote your shares in their discretion for another person nominated by the board.
Our policy on majority voting for directors contained in our corporate governance guidelines requires any proposed nominee for re-election as a director to tender to the board, prior to nomination, his or her irrevocable resignation from the board that will be effective, in an uncontested election of directors only, upon:
receipt of a greater number of votes “against” than votes “for” election at our annual meeting of stockholders; and
acceptance of such resignation by the board of directors.
Following certification of the stockholder vote, the nominating and governance committee will promptly recommend to the board whether or not to accept the tendered resignation. The board will act on the nominating and governance committee’s recommendation no later than 90 days following the date of the annual meeting.

Brokers may not vote your shares on the election of directors if you have not given your broker specific instructions on how to vote. Please be sure to give specific voting instructions to your broker so your vote can be counted.

Board Evaluations and Process for Selecting Directors
Our corporate governance guidelines require that the board, in coordination with the nominating and governance committee, annually reviews and evaluates the performance and functioning of the board and its committees.
The board evaluation process includes the following steps:
mdu-20230323_g40.jpg
1QUESTIONNAIRES
During 2022, each director completed an anonymous written questionnaire with the opportunity to provide comments. In addition, committee members completed a separate written questionnaire related to the operation of the respective committees.
mdu-20230323_g41.jpg
2BOARD SUMMARY AND FEEDBACK
The results of the written questionnaires were anonymously aggregated and provided to the board and each committee. Key strengths and opportunities for improvement of the board and each committee were reviewed and discussed in an executive session of the board in connection with this process.
mdu-20230323_g42.jpg
3BOARD SUCCESSION
As part of the annual board evaluation process, the nominating and governance committee evaluates our directors considering the current needs of the board and the company. This evaluation supports the nominating and governance committee’s consideration of board succession and potential director recruitment throughout the year.
Director Qualifications, Skills, and Experience
Director nominees are chosen to serve on the board based on their qualifications, skills, and experience, as discussed in their biographies, and how those characteristics supplement the resources and talent on the board and serve the current needs of the board and the company. Our governance guidelines provide that directors are not eligible to be nominated or appointed to the board if they are 76 years or older at the time of the election or appointment. The board does not have term limits on the length of a director’s service.

In making its nominations, the nominating and governance committee assesses each director nominee by a number of key characteristics, including character, success in a chosen field of endeavor, background in publicly traded companies, independence, and willingness to commit the time needed to satisfy the requirements of board and committee membership. Although the committee has no formal policy regarding diversity, the board is committed to having a diverse and broadly inclusive membership. In recommending director nominees, the committee considers diversity in gender, ethnic background, geographic area of residence, skills, and professional experience.

Board Composition and Refreshment
The nominating and governance committee is committed to ensuring that the board reflects a diversity of experience, skills, and backgrounds to serve the company’s governance and strategic needs. In recognition of the company’s commitment to diversity, the company was recognized in 2022 by 50/50 Women on Boards™ as a “3+” company for having three or more women on its board of directors.
Each of the nominees has been nominated for election to the board of directors upon recommendation by the nominating and governance committee and each has decided to stand for election.
In evaluating the needs of the board and the company, the nominating and governance committee focuses on identifying board candidates that will add gender and ethnic diversity along with relevant industry and leadership experience to the board, as well as a background and core competencies in the fields of technology, cybersecurity, and public company governance. To support this process, the nominating and governance committee engaged an independent global search firm in 2021 to assist with identifying, evaluating, and recruiting a diverse pool of potential director candidates, which led to the appointment of German Carmona Alvarez in 2022. Potential director nominees were brought to the attention of the nominating and governance committee by board members, management, advisory firms, and various organizations.
The nominating and governance committee continues to identify individuals as potential board of director candidates, particularly individuals with industry experience to support the company’s strategy to create two pure-play companies of regulated energy delivery and construction materials, while pursuing organic growth opportunities and strategic acquisitions. The nominating and governance committee identified and recommended German Carmona Alvarez be appointment to the board in 2022 based on his expertise with human capital management, digital and information technology, finance, and mergers and acquisitions as well as his addition to the board’s expertise and diversity.
By tenure, if the nominees are elected, the board will be comprised of three directors who have served from 0-4 years, three directors who have served from 5-10 years, and four directors who have served over 11 years. The nominating and governance committee believes this mix of director tenures provides a balance of experience and institutional knowledge with fresh perspectives. The nominating and governance committee also takes into consideration any written agreement for director nominations the company is a party to such as the Cooperation Agreement.

Board Leadership Structure
The board separated the positions of chair of the board and chief executive officer in 2006, and our bylaws and corporate governance guidelines currently require that our chair be independent. The board believes this structure provides balance and is currently in the best interest of the company and its stockholders. Separating these positions allows the chief executive officer to focus on the full-time job of running our business, while allowing the chair of the board to lead the board in its fundamental role of providing advice to and independent oversight of management. The chair meets and confers regularly between board meetings with the chief executive officer and consults with the chief executive officer regarding the board meeting agendas, the quality and flow of information provided to the board, and the effectiveness of the board meeting process. The board believes this split structure recognizes the time, effort, and energy the chief executive officer is required to devote to the position in the current business environment as well as the commitment required to serve as the chair, particularly as the board’s oversight responsibilities continue to grow and demand more time and attention. The fundamental role of the board of directors is to provide oversight of the management of the company in good faith and in the best interests of the company and its

stockholders. HavingThe board believes having an independent chair is a means to ensure the chief executive officer is accountable for managing the company in close alignment with the interests of stockholders including with respect to risk management as discussed below. AnThe board has found that an independent chair is in a position to encourage frank and lively discussions including during regularly scheduled executive sessions consisting of only independent directors and to assure that the company has adequately assessed all appropriate business risks before adopting its final business plans and strategies. The board believes that having separate positions and having an independent outside director serve as chair is the appropriate leadership structure for the company at this time and demonstrates our commitment to good corporate governance.
Board’s Role in Risk Oversight
Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including economic risks, strategic risks, operational risks, environmental and regulatory risks, the impact of competition,competitive risks, climate and weather conditions, limitations on our ability to pay dividends, pension plan obligations, cyberattacks or acts of terrorism, and third party liabilities. Management is responsible for identifying material risks, implementing appropriate risk management strategies, and providing information regarding material risks and risk management to the board. The board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate for identifying, assessing, and managing risk. Management is responsible for identifying material risks, implementing appropriate risk management and mitigation strategies, and providing information regarding material risks and risk management and mitigation to the board. The company’s risk oversight framework also aligns with its disclosure controls and procedures. For example, the company’s quarterly and annual financial statements and related disclosures are reviewed by the disclosure committee, which includes certain senior management, who participate in the risk assessment practices described below.
The board believes establishing the right “tone at the top” and full and open communication between management and the board of directors are essential for effective risk management and oversight. Our chair meets regularly with our president and chief executive officer and other senior officers to discuss strategy and risks facing the company. The chair of the board and chairs of each of the board’s standing committees meet with our chief executive officer, chief financial officer, and general counsel to discuss risks and presentations to the board regarding risks. Senior management attends the quarterly board meetings and is available to address any questions or concerns raised by the board on risk management-related and any other matters. Each quarter, the board of directors receivesand its applicable committees receive presentations from senior management on enterprise risk management issues and strategic matters involving our operations. Senior management annually presents an assessment to the board of critical enterprise risks that threaten the company’s strategy and business model, including risks inherent in the key assumptions underlying the company’s business strategy for value creation. Periodically, the board receives presentations from external experts on matters of strategic importance to the board. At least annually, the board holds strategic planning sessions with senior management to discuss strategies, key challenges, and risks and opportunities for the company.
WhileIn addition, in 2022 the company developed a survey completed by both the board is ultimately responsible forof directors and members of the management policy committee to identify critical enterprise risks. The company believes this program, which was designed to enable effective and efficient identification of, and visibility into, critical enterprise risks over the short, intermediate, and long-term, and to facilitate the incorporation of risk considerations into decision making across the company, and assessing and managing the company’s legal, regulatory, and other compliance obligations on a global basis, provides valuable insight to the board of directors in its risk oversight efforts. In particular, the company believes its enterprise risk management programs help clearly define risk management roles and responsibilities among the board, its committees and management, bring together senior management to discuss risk, promote visibility and constructive dialogue around the risks relevant to the company’s strategy and operations and helps facilitate appropriate risk response strategies at our company, our three standingthe board of directors, board committees, assist the board in fulfilling its oversight responsibilities in certain areas of risk.and management.

EXECUTIVE COMPENSATION

ITEM 2. ADVISORY VOTE TO APPROVE THE FREQUENCY OF FUTURE ADVISORY VOTES TO APPROVE THE COMPENSATION PAID TO THE COMPANY’S NAMED EXECUTIVE OFFICERS
In accordance with Section 14A of the Securities Exchange Act of 1934 and Rule 14a-21(b), we are asking our stockholders to indicate, on an advisory basis, whether future advisory votes to approve the compensation paid to our named executive officers should be held every year, every two years, or every three years. This proposal is also known as a “say-on-frequency” proposal.
Our board of directors has determined that our stockholders should have the opportunity to vote on the compensation of our named executive officers every year. The board of directors believes that giving our stockholders the right to cast an advisory vote every year on the compensation of our named executive officers is a good corporate governance practice and is in the best interests of our stockholders. Annual advisory votes provide the highest level of accountability and direct communication with our stockholders.
The board has discussed and carefully considered the alternatives regarding the frequency of future advisory votes to approve executive compensation in an effort to determine the approach that would best serve the company and its stockholders. Our board has considered several factors supporting an annual vote, including:
An annual say-on-pay vote is consistent with past practice, as we have been conducting an annual vote since 2011.
An annual say-on-pay vote provides us with immediate and direct input from our stockholders on our compensation principles and practices as disclosed in the proxy statement every year.
An annual say-on-pay vote provides frequent feedback from our stockholders, which is consistent with our efforts to seek input from our stockholders regarding corporate governance and our compensation philosophy.
The lack of an annual say-on-pay vote might make it more difficult for us to understand the outcome of a stockholder vote as to whether the stockholder vote pertains to the compensation disclosed in the current year proxy statement or pay practices over the previous year or two years. As a result, a frequency other than annual might make it more difficult for the board to understand and respond appropriately to the message being communicated by our stockholders.
Our stockholders voted to recommend an annual say-on-pay vote at our 2017 annual meeting of stockholders.
By voting on this Item 2, stockholders are not approving or disapproving the board of directors’ recommendation, but rather are indicating whether they prefer an advisory vote on named executive officer compensation be held every year, every two years, or every three years. Stockholders may also abstain from voting.
Although the board of directors intends to carefully consider the voting results of this proposal, it is an advisory vote and the results will not be binding on the board of directors or the company, and the board of directors may decide that it is in the best interests of our stockholders and the company to hold an advisory vote on executive compensation more or less frequently than the option selected by our stockholders. In accordance with Section 14A of the Exchange Act, the next “say-on-frequency” vote will be held no later than the annual meeting of the stockholders in 2029.
The board of directors recommends that an advisory vote on compensation paid to our named executive officers be held every year.
The frequency of every year, every two years, or every three years that receives the most votes of our common stock present in person or represented by proxy at the meeting and entitled to vote on the proposal will be the frequency for the advisory vote on executive compensation that has been recommended by our stockholders. Abstentions will not count as votes for or against any frequency. Broker non-votes are not counted as voting power present and, therefore, are not counted in the vote.

Annual Base Salary
We provide our executive officers with base salary at a sufficient level to attract recruit, and retain executives with the knowledge, skills, and abilities necessary to successfully execute their job responsibilities. Consistent with our compensation philosophy of linking pay to performance, our executives receive a relativerelatively smaller percentage of their overall target compensation in the form of base salary. In establishing base salaries, the compensation committee considers each executive’s individual performance, the scope and complexities of their responsibilities, internal equity, and whether the executive’s base salary is competitive as measured against the base salaries of similarly situated executives in our compensation peer group and market compensation data.
Annual Cash Incentive Awards
AnnualWe linked our 2022 annual cash incentive awards for our executive officers are linked to performance by rewarding achievement of operational and financial goalsperformance measures and ensuring our executive officers are focused and accountable for our growth and profitability. The design of the annual cash incentive award opportunities for 2017 was the same as the design used in 2016. Each executive iswas assigned a target annual incentive award based on a percentage of the executive’s base salary. The actual annual cash incentive realized iswas determined by multiplying the target award by the payout percentage associated with the achievement of the executive’s performance measures.
The compensation committee selectedannual cash incentive award for corporate executives (including our CEO and CFO) was based solely on the company’s overall earnings per share (EPS) as adjusted and as described under the “Annual Cash Incentives” section in this Compensation Discussion and Analysis. This incentivizes the corporate executives to assist the business segments in their success and further links executive pay with the performance of the company.
Eighty percent of the annual cash incentive award for our business segment executives was based on specific business segment financial performance measures for each business segment executive which represented 80% of their annual award opportunity.selected by the compensation committee. The other 20% of the business segment executives’ annual incentive award opportunity was based on the achievement of overall company earnings per share (EPS).EPS as adjusted and as described under the “Annual Cash Incentives” section in this Compensation Discussion and Analysis. These measures incentivize our business segment executives to focus on the success and performance of their individual business segmentsegments while keeping the overall financial success of the company in mind.
TheIn February 2022, the compensation committee approved the DEI modifier as part of the 2022 annual cash incentive award program for corporateexecutive officers. The DEI modifier is based upon the company’s achievement of certain initiatives to attract, retain, and develop a diverse and inclusive workforce. It includes a focus on representation of diverse employees in executive succession plans, outreach efforts to attract diverse candidates for open positions, implementing enhanced diversity, equity, and inclusion training as well as mentoring for new employees. The DEI modifier also includes the development of enhanced internal employee data dashboards to further support the company’s efforts to attract, retain, and develop a diverse and inclusive workforce.

Allocation of Total Target Compensation for 20172022
Total target compensation consists of base salary plus target annual and long-term incentive compensation. Performance-based compensation accounts for over 75% of our CEO’s and on average approximately 60% of our other current named executive officers’ total target compensation. Incentive compensation, which consists of annual cash incentive and three-year performance share award opportunities,long-term incentive awards vesting after three years, comprises the largest portion of our named executive officers’ total target compensation because:
our named executive officers are in positions to drive, and therefore bear high levels of responsibility for our corporate performance;
incentive compensation is dependent upon our performance;
incentive compensation helps ensure focus on performance measures that are aligned with our overall strategy; and
equity awards align the interests of the named executive officers are aligned with those of stockholders by making a significant portion of their target compensation contingent upon results beneficial to stockholders.stockholders;
To fosterour named executive officers are in positions of authority to drive results, and reward long-term growth,therefore bear high levels of responsibility for our corporate performance;
variable compensation helps ensure focus on the goals that are aligned with overall company strategy; and
incentive compensation is at risk and dependent upon company performance and the satisfaction of performance objectives.
The compensation committee generally allocates a higher percentage of total target compensation to the target long-term incentive than to the target annual incentive for our higher level executives because they are in a better position to influence ourthe company’s long-term performance. The long-term incentive awards if earned by achieving performance measures, are paid in company common stock. These awards, combined with our stock retention requirements and our stock ownership policy, promote ownership of our stock by the executive officers. TheAs a result, the compensation committee believes as stockholders, the executive officers, as stockholders, will be motivated to deliver results that buildlong-term value to all stockholders.

For corporate executives,earnings per share. Our CEO and CFO earn their annual cash incentive awards are determined asaward based solely on the sum of the weighted portion of the percentage award payout of each business segment based upon achievement of its performance measures and weighted by the business segment’s invested capital relative to the overall company invested capital.earnings per share. Through this, our business segment executives are incentivized to primarily focus on the success and performance of their business segmentsegments while keeping the overall financial success of the company in mind, whereas our corporate executives are incentivized to assist in the success and performance of all lines of business.
The compensation committee considered and selected the following financial performance measures to ensure that compensation to the executives reflects the success of their respective business segments and the company as well as value provided to our stockholders. Each business segment president’s performance measures include a corporateoverall company.

The compensation committee selected earnings per share from continuing operations as the shared financial metric as it is a key indicator of company results and used to communicate annual performance measure representing 20%expectations with the financial community. The earnings per share target of $2.07 reflects our 2022 financial goal to achieve an estimated return on invested capital of 7.7%.
MDU Resources Group, Inc. Proxy Statement 56

Proxy Statement
The compensation committee selected EBITDA from continuing operations as the performance metric for the construction materials and contracting and construction services segment presidents as it is a financial performance metric common to the construction industry and encourages the presidents to focus on growth by excluding the impact of items such as taxes, interest, depreciation and amortization from the performance result which are largely out of their control. The target award opportunityof $331 million in EBITDA from continuing operations for the construction materials and businesscontracting segment and $180 million in EBITDA from continuing operations for the construction services segment reflects the financial goal needed to achieve returns on invested capital of 9.5% and 24.1% for the construction materials and contracting and construction services segments, respectively.
The compensation committee selected earnings from continuing operations as the performance metric for the electric and natural gas distribution segments as regulated utilities are valued based on earnings potential and rate base. The 2022 target of $110 million reflects the financial goal needed to achieve a return on invested capital of 4.9% and the continued investment in infrastructure and regulatory recovery from completed and pending rate cases.
In addition to the financial performance measures, representing 80%the environmental and sustainability committee approved and recommended a DEI modifier be included as part of the award opportunity. The followingexecutive’s 2022 annual incentive performance measures for 2017 were adoptedwhich was then approved by the compensation committee at its February 2022 meeting. The DEI modifier is a separate performance measure, independent of the achievement of the financial performance measures and is based on the compensation committee’s assessment of management’s progress toward the completion of the following DEI initiatives:
Enhance the formal succession planning process to include the review of the positions of all Section 16 officers, key executives and business segment officers and to ensure diverse representation in terms of gender, ethnicity, individuals with disabilities and veteran status and the development of candidates being prepared for these positions.
Increase outreach activities and efforts aimed at attracting diverse candidates to positions within our businesses.
Enhance new employee onboarding processes to include DEI training and formal mentoring programs.
Implement a consistent human resources dashboard across all businesses to build baseline information and track key metrics to provide insight into the make-up and diversity of our employee population.
The DEI modifier applies equally to all executives and adds or deducts up to 5% of the executives annual incentive target based on the compensation committee’s assessment.
All financial performance measures are from continuing operations plus earnings or losses from any discontinued operations after December 31, 2021. To incentivize executives to make decisions that have long-term positive impact, even at the expense of short-term results, and to prevent one-time gains and losses from having an undue impact on incentive payments, the compensation committee designed its annual incentive measures to allow for adjustments for certain unplanned events that impact our performance targets but are not indicative of underlying business performance. The compensation committee may approve adjustments to the financial results to remove the following items, as applicable, from the performance measure:
The negative effect on earnings/EBITDA from asset sales/dispositions/retirements.
The effect on earnings/EBITDA from withdrawal liabilities relating to multiemployer pension plans.
The effect on earnings/EBITDA from transaction costs incurred for acquisitions or mergers.
The effect on earnings from unanticipated changes and interpretation of tax law.
The compensation committee will consider for removal the positive effect on earnings/EBITDA from assets sales/dispositions/retirements if it determines the positive effect is not indicative of underlying business performance.
For the 2022 annual cash incentive, the compensation committee approved adjustments to the construction materials and contracting segment EBITDA from continuing operations to remove the effect of transaction costs incurred for acquisitions and mergers. In the calculation of EPS from continuing operations, the compensation committee approved adjustments for the businesseffect of transaction costs incurred for acquisitions and mergers, costs incurred associated with the company’s intent to separate the construction materials and contracting segment presidents (exclusivepursuant to a tax-free spinoff and, costs incurred in connection with the company’s strategic review to optimize the value of the construction services segment.

Long-Term Incentives
As in the past, the compensation committee used performance shares as the formAll of long-term incentive compensation for 2017 and established the company’s total stockholder return as a percentile of the total stockholder return for the peer group companies over a three-year period as the performance measure for vesting of long-term incentive compensation.
Total stockholder return is the percentage change in the value of an investment in the common stock of a company from the closing price on the last trading day in the calendar year preceding the beginning of the performance period through the last trading day in the final year of the performance period. It is assumed that dividends are reinvested in additional shares of common stock at the frequency paid during the performance period. The compensation committee selected total stockholder return as the performance measure because long-term executive incentive compensation should align with our long-term performance in stockholder return as compared to other public companies in our industries.
Depending on our total three-year stockholder return compared to the total three-year stockholder returns of our peer group companies, vesting of performance share award opportunities for our named executive officers can range from 0% to 200%participated in the 2022 long-term incentive plan which consists of 75% performance shares that align long-term compensation with the achievement of pre-determined financial performance measures and 25% time-vesting restricted stock units that incentivize retention of our executives and alignment with the interests of our stockholders. Long-term incentive compensation comprised 57.7% of the CEO’s 2022 total target award.

2023-2025 Long-Term Incentive Awards
The compensation committee did not award performance shares to the executive officers for the 2023-2025 performance period due to the company’s pending plans to separate the construction materials and contracting segment into a standalone public company and exploring strategic alternatives for the construction services segment in 2023. The committee awarded only time-vesting restricted stock units due to the company’s significant strategic initiatives underway and as a means of retention for executive officers of both entities during the pending separation process. The compensation committee intends to resume awarding performance vesting shares in 2024.
Stock Retention Requirement
The named executive officers must retain 50% of the net after-tax performance shares vested pursuant to the long-term incentive award untilawards for the earlier of two years from the date the vested shares are issued or the executive’s termination of employment.

Compensation Governance
Impact of Tax and Accounting Treatment
The compensation committee may consider the impact of tax and/or accounting treatment in determining compensation.
Section 162(m) of the Internal Revenue Code limits the deductibility of certain compensation to $1 million paid to certain officers as a business expense in any tax year. When the compensation committee made its decisions for 2017 compensation, the tax code provided that compensation that qualified as “performance-based” was excluded from the $1 million deductibility limit if, among other requirements, the compensation was payable only upon attainment of pre-established, objective performance goals under a plan approved by our stockholders. Legislation signed into law in December 2017 (Tax Reform), however, expanded the number of individuals covered by the Section 162(m) deductibility limit and repealed the exception for performance-based compensation, effective for taxable years beginning after December 31, 2017. Incentive compensation approved by the compensation committee prior to the Tax Reform for our CEO and those executive officers whose overall compensation was likely to exceed $1 million was generally structured to meet the requirements for deductibility for purposes of Section 162(m). As a result of the Tax Reform, compensation paid to our covered executive officers in excess of $1 million will not be deductible, unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.
The compensation committee did not make any adjustments to the 2022 compensation program to address the impact of tax or accounting treatment. The compensation committee may also considersconsider the accounting and cash flow implications of various forms of executive compensation. We expense salaries and annual incentive compensation as earned. For our equity awards, we record the accounting expense in accordance with Financial Accounting Standards BoardCodification Topic 718, which is generally expensed over the vesting period.

If an executive chooses to defer all or part of an annual incentive, we credit the deferral with interest at a rate determined by the compensation committee. For 2017, the compensation committee chose to use an interest rate of 4.38% based on an average of the Moody’s U.S.Our Long-Term Corporate Bond Yield Average for “A” and “Baa” rated companies. The compensation committee’s reasons for using this interest rate recognized incentive deferrals are a low-cost source of capital for the company and are unsecured obligations and, therefore, carry a higher risk to the executives.
Clawback
In February 2016, we amended our Long-TermPerformance-Based Incentive Plan and Executive Incentive Compensation Plan sections regarding the repayment of incentive compensation due to accounting restatements,EICP include provisions commonly referred to as a clawback policy. The compensation committee may, or shall if required, take action to recover incentive-based compensation from specific executives in the event the company is required to restate its financial statements due to material noncompliance with any financial reporting requirements under the securities laws.
Policy Regarding Hedging Stock Ownership
Our executive compensation policy prohibits executive officers, which includes our named executive officers, from hedging their ownership of company common stock. Executives may not enter into transactions that allow the executive to benefit from devaluation of our stock or otherwise own stock technically but without the full benefits and risks of such ownership. See the section entitled “Security Ownership” for our policy on margin accounts and pledging of our stock.
COMPENSATION COMMITTEE REPORT
The compensation committee is primarily responsible for reviewing, approving, and overseeing the company’s compensation plans and practices and works with management and the committee’s independent compensation consultant to develop the company executive compensation programs. The compensation committee has reviewed and discussed the Compensation Discussion and Analysis required by Regulation S-K,
Item 402(b), with management. Based on the review and discussions referred to in the preceding sentence, the compensation committee recommended to the board of directors that the Compensation Discussion and Analysis be included in our Proxy Statement on Schedule 14A.

Narrative Discussion Relating to the Summary Compensation Table

and Grants of Plan-Based Awards Table
Annual Incentive
The compensation committee recommended the 20172022 annual cash incentive award opportunities for our named executive officers and the board approved these opportunities at its meeting on February 15, 2017.17, 2022. The award opportunitiesawards at threshold, target, and maximum are reflected in columns (c), (d), and (e), respectively, of the Grants of Plan-Based Awards Table. The actual amount paid with respect to 20172022 performance is reflected in column (g) of the Summary Compensation Table.
As described in the “Annual Cash Incentives” section of the “Compensation Discussion and Analysis,” payment of annual award opportunitiescash incentive awards is dependent upon achievement of performance measures; actual payout may range from 0% to 200% of the target except for the construction materials and contracting and construction services segments which may range from 0% to 240%.
Messrs. Goodin, Schwartz, Barney, and Thiede received their 2017 The DEI modifier adds or deducts up to 5% of the executives’ annual incentive award opportunities pursuant to the Long-Term Performance-Based Incentive Plan. To be eligible to receive a payment, they must remain employed by the company through December 31, 2017. Mr. Schwartz resigned his position effective September 29, 2017, and therefore was not eligible to receive an annual incentive award.
The performance measures associated with the annual incentive may not be adjusted if the adjustment would increase their annual incentive award payment, unlesstarget based on the compensation committee determined and established the adjustment in writing within 90 days of the beginning of the performance period. The compensation committee may at its sole discretion use negative discretion based on subjective or objective measures and adjust any annual incentive award payment downward.committee’s assessment.
Mr. Vollmer and Ms. KivistoAll our named executive officers were awarded their annual incentive opportunitiescash incentives pursuant to the MDU Resources Group, Inc.

eligible to receive ana prorated award, but executives who terminate employment for other reasons are not eligible for an award. The compensation committee generally does not modify the performance measures; however, if major unforeseen changes in economic and environmentalyears of unusually adverse or favorable external conditions or other unforeseen significant factors beyond the control of management, substantially affected management’s ability to achieve the specified performance measures, the compensation committee in consultation with the CEO, may modify the performance measures. In determining the 2022 annual incentive awards, the compensation committee approved adjustments to earnings from continuing operations of $612,000 after-tax for costs incurred associated with mergers and acquisitions at the construction materials and contracting segment and $12.7 million after-tax for costs incurred in connection with the company’s intent to separate the construction materials and contracting segment pursuant to a tax-free spinoff and the strategic review to optimize the value of the construction services segment. The compensation committee has full discretion to determine the extent to which goals have been achieved, the payment level,

and whether to adjust payment of awards downward based upon individual performance. For further discussion of the specific 20172022 incentive plan performance measures and results, see the “Annual Cash Incentives” section in the “Compensation Discussion and Analysis.”
Long-Term Incentive
The compensation committee recommended long-term incentive award opportunitiesawards for the named executive officers in the form of 75% performance shares and 25% time-vesting restricted stock units, and the board approved the award opportunitiesawards at its meeting on February 15, 2017.17, 2022. The portion of the long-term incentive opportunitiesassociated with performance shares are presented as the number of performance shares at threshold, target, and maximum in columns (f), (g), and (h) of the Grants of Plan-Based Awards Table. The value of the long-term performance-based incentive opportunities is based on the aggregate grant date fair value and is reflectedincluded in the amount recorded in column (e) of the Summary Compensation Table and column (l) of the Grant of Plan-Based Awards Table.
Depending on the achievement of the performance measures associated with our 2017-2019 total stockholder return compared to the total three-year stockholder returns2022-2024 performance period measured as of our peer group companies,December 31, 2024, executives will receive from 0% to 200% of the target performance share awards in February 2020.2025. We also will pay dividend equivalents in cash on the number of shares actually vested for the performance period. The dividend equivalents will be paid in 2020February 2025 if and to the extent they vest and at the same time as the performance share awards are issued. Insettled.
The portion of the event the company’s 2017-2019 total stockholder return is negative,long-term incentive associated with time-vesting restricted stock units are presented as the number of shares that would otherwise vest for the performance period will be reduced from 50% to 100%. For further discussion of the specific long-term incentive plan, see the “Long-Term Incentives” section in the “Compensation Discussion and Analysis.”
Nonqualified Defined Contribution Plan
The CEO recommends participants and contribution amounts to the Nonqualified Defined Contribution Plan which are approved by the compensation committee of the board of directors.

SISP benefits are determined by reference to levels defined within the plan. Our compensation committee, after receiving recommendations from our CEO, determined each participant’s level within the plan.

40% vesting for four years of participation; and
an additional 10% vesting for each additional year of participation up toschedule where participants are 100% vesting forvested after ten years of participation.participation in the plan.
Participants can elect to receive the Basic SISP as:
monthly retirement benefits only;
monthly death benefits paid to a beneficiary only; or
a combination of retirement and death benefits, where each benefit is reduced proportionately.
Regardless of the election, if the participant dies before the SISP retirement benefit commences, only the SISP death benefit is provided.
Basic SISP benefits vested as of December 31, 2004, are grandfathered under Section 409A of the Internal Revenue Code (Section 409A) and are subject to the SISP provisions then in effect. Typically, the grandfathered Section 409A SISP benefits are paid over 15 years, with benefits commencing when the participant attains age 65 or when the participant retires if they work beyond age 65. Basic SISP benefits vesting after December 31, 2004, are governed by amended provisions in the plan intended to comply with Section 409A. The SISP benefits for key employees as defined by Section 409A commence six months after the participant attains age 65 or when the participant retires if they work beyond age 65. The benefits are paid over a 173-month period where the first payment includes the equivalent of six months of payments plus interest equal to one-half of the annual prime interest rate on the participant’s last date of employment.

Excess SISP Benefits
Excess SISP is an additional retirement benefit relating to Internal Revenue Code limitations on retirement benefits provided under the pension plans. Excess SISP benefits are equal to the difference between the monthly retirement benefits that would have been payable to the participant under the pension plans absent the limitations under the Internal Revenue Code and the actual benefits payable to the participant under the pension plans. Participants are only eligible for the Excess SISP benefits if the participant is fully vested under the pension plan, their employment terminates prior to age 65, and benefits under the pension plan are reduced due to limitations under the Internal Revenue Code on plan compensation.

In 2009, the SISP was amended to limit eligibility for the Excess SISP benefit. Mr. Goodin is the only named executive officer eligible for the Excess SISP benefit and must remain employed with the company until age 60 in order to receive the benefit. Benefits generally commence six months after the participant’s employment terminates and continue to age 65 or until the death of the participant, if prior to age 65.
Both Basic and Excess SISP benefits are forfeited if the participant’s employment is terminated for cause.

Potential Payments upon Termination or Change of Control
The Potential Payments upon Termination or Change of Control Table shows the payments and benefits our named executive officers would receive in connection with a variety of employment termination scenarios or upon a change of control. The scenarios include:
Voluntary or Not for Cause Termination;
Death;
Disability;
Change of Control with Termination; and
Change of Control without Termination.
For the named executive officers, the information assumes the terminations or the change of control occurred on December 31, 2017. Mr. Schwartz received no actual termination payments upon his resignation effective September 29, 2017.2022.
The table excludes compensation and benefits that our named executive officers would have already earnedearn during their employment with us whether or not a termination or change of control event had occurred or providedoccurred. The tables also do not include benefits under plans or arrangements generally available to all salaried employees and that do not discriminate in favor of the named executive officers, and that are generally available to all salaried employees, such as benefits under our qualified defined benefit pension plan (for employees hired before 2006), accrued vacation pay, continuation of health care benefits, and life insurance benefits. The tables also do not include deferred compensation under our Executive Incentive Compensation Plan, Nonqualified Defined Contribution Plan, or deferred annual compensationMDU Resources Group, Inc.

MDU Resources Group, Inc. Proxy Statement 51


Proxy Statement

All named executive officers received their equity share awards under the Long-Term Performance-Based Incentive Plan (LTIP) which consist of performance share awards for the 2020-2022, 2021-2023 and 2022-2024 vesting periods and restricted stock units for the 2021-2023 and 2022-2024 vesting periods.
Upon a change of control performance share awards under the LTIP would be deemed fully earned and vest at their target levels for the named executive officers. For this purpose, the term “change of control”(with or without termination), is defined in the LTIP as:
the acquisition by an individual, entity, or group of 20% or more of our outstanding common stock;
a majority of our board of directors whose election or nomination was not approved by a majority of the incumbent board members;
consummation of a merger or similar transaction or sale of all or substantially all of our assets, unless our stockholders immediately prior to the transaction beneficially own more than 60% of the outstanding common stock and voting power of the resulting corporation in substantially the same proportions as before the merger, no person owns 20% or more of the resulting corporation’s outstanding common stock or voting power except for any such ownership that existed before the merger and at least a majority of the board of the resulting corporation is comprised of our directors; or
stockholder approval of our liquidation or dissolution.
As a result, in the case of a change of control (with or without termination) both performance share awards and restricted stock unit awards would be deemed fully earned and vest at their target levels for the named executive officers.

Proxy Statement
For termination scenariosour performance share awards, if a participant terminates employment for any reason other than a change of control our award agreements provide thator prior to reaching age 55 with 10 years of service, their performance share awards are forfeited if the participant’s employment terminates before the participant has reached age 55 and completed 10 years of service.forfeited. If a participant’sparticipant terminates employment is terminatedfor any reason other than for cause after reaching age 55 and completing 10 years of service, performance sharesshare awards are prorated as follows:
termination of employment during the first year of the performancevesting period = sharesequity share awards are forfeited;
termination of employment during the second year of the performancevesting period = performance sharesequity share awards earned are prorated based on the number of months employed during the performancevesting period; and
termination of employment during the third year of the performancevesting period = full amount of any performance sharesequity share awards earned are received.
Under the scenarios of voluntary or not for cause termination, scenarios,disability or death, Messrs. Goodin, Barney, and Thiede would receive performance shares as they have each reached age 55 and have 10 or more years of service. The number of performance shares received would be based on the following:
2015-20172020-2022 performance shares would vest based on the achievement of the performance measure for the period ended December 31, 2017,2022, which was 144%91.7%;
2016-20182021-2023 performance shares would be prorated at 24 out of 36 months (2/3) of the performancevesting period and vest based on the actual achievement of the performance measure for the period ended December 31, 2018.2023. For purposes of the Potential Payments upon Termination or Change of Control Table, the vestingperformance achievement for the performance period is shown at 100%;target; and
2017-20192022-2024 performance shares would be forfeited.
Neither Ms. Kivisto nor Mr. Vollmer have reached age 55; therefore, they are not eligible for vesting of performance shares in the event of their termination, death or disability.
Our restricted stock unit award agreement provides that restricted stock unit share awards are forfeited if the participant’s employment terminates for situations other than death, disability or before the participant has reached age 55 with 10 years of service. If a participant’s employment terminates after reaching age 55 and completing 10 years of service, restricted stock unit share awards are prorated as follows:
termination of employment during the first year of the vesting period = restricted stock unit awards are forfeited;
termination of employment during the second year of the vesting period = restricted stock unit awards earned are prorated based on the number of months employed during the vesting period; and
termination of employment during the third year of the vesting period = full amount of any restricted stock unit awards earned are received.
In situations of death or disability, the restricted stock unit awards earned would be prorated based on the number of full months of employment completed prior to death or disability during the vesting period.
For 2022, our awards include restricted stock units for the 2021-2023 and 2022-2024 vesting periods. In the case of voluntary or not for cause termination, Messrs. Goodin, Barney and Thiede would forfeit their 2022-2024, restricted stock units but receive their 2021-2023 restricted stock units based on a proration of 24 out of 36 months (2/3). Since neither Ms. Kivisto or Mr. Vollmer have reached age 55, in the case of voluntary or not for cause termination, they would forfeit their 2021-2023 and 2022-2024 restricted stock unit awards.
In the case of termination due to death or disability, all our named executive officers would receive 1/3 of the granted shares associated with the 2022-2024 award based on 12 out of 36 months of the vesting period and 2/3 of the granted shares associated with the 2021-2023 award based on 24 out of 36 months of the vesting period.
For purposes of calculating the performance share and restricted stock unit award value shown in the Potential Payments upon Termination or Change of Control Table, the number of vesting shares was multiplied by the average of the high and low stock price for the last market day of the year, which was December 29, 2017.31, 2022. Dividend equivalents based on the number of vesting shares are also included in the amounts presented.
Neither Ms. Kivisto nor Mr. Vollmer have reached age 55; therefore, they are not eligible for vesting of performance shares in the event of their termination.

Severance
None of the current named executive officers have employment or severance agreements with the company. The compensation committee generally considers providing severance benefits on a case-by-case basis. Because severance payments are discretionary, no amounts are presented in the tables.

CEO Pay Ratio Disclosure
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing information regarding the relationship of the annual total compensation of David L. Goodin, our president and chief executive officer, to the annual total compensation of our median employee.
Our employee workforce fluctuates during the year largely depending on the seasonality, number, and size of construction project activity conducted by our businesses. Approximately 49.8%59% of our employee workforce is employed under union bargained labor contracts which define compensation and benefits for participants which may include payments made by the company associated with employee participation in union benefit and pension plans.
We identified the median employee by examining the 20172022 taxable wage information for all individuals on the company’s payroll records as of December 31, 2017,2022, excluding Mr. Goodin. All of the company’s employees are located in the United States. We made no adjustments to annualize compensation for individuals employed for only part of the year. We selected taxable wages as reported to the Internal Revenue ServiceIRS on Form W-2 for 20172022 to identify the median employee as it includes substantially all of the compensation for our median employee and provided a reasonably efficient and economiccost-effective manner for the identification of the median employee. Our median employee works for a subsidiary of our gas distribution segment. He is a unionized employeeconstruction materials and contracting segment with compensation consisting of wages, meal allowances,bonus, company 401(k) matching 401(k) contributions and a years of service award. Our median employee does not participate in the company’s pension plan since he joined the company in 2011, after the plan was frozen. He does receive an additional 5% company match to his 401(k) plan in lieu of pension contributions.profit sharing, life insurance premiums, car allowance, and per diem.
Once identified, we categorized the median employee’s compensation to correspond tousing the same methodology as the compensation components as reported in the Summary Compensation Table. For 2017,2022, the total annual compensation of Mr. Goodin as reported in the Summary Compensation Table included in this Proxy Statement was $4,058,001,$5,257,289, and the total annual compensation of our median employee was $84,883.$96,652. Based on this information, the 20172022 ratio of annual total compensation of Mr. Goodin to the median employee was 4854 to 1.

AUDIT MATTERS
ITEM 3:4: RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 20182023
The audit committee at its February 20182023 meeting appointed Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2018.2023. The board of directors concurred with the audit committee’s decision. Deloitte & Touche LLP has served as our independent registered public accounting firm since fiscal year 2002.
Although your ratification vote will not affect the appointment or retention of Deloitte & Touche LLP for 2018,2023, the audit committee will consider your vote in determining its appointment of our independent registered public accounting firm for the next fiscal year. The audit committee, in appointing our independent registered public accounting firm, reserves the right, in its sole discretion, to change an appointment at any time during a fiscal year if it determines that such a change would be in our best interests.
A representative of Deloitte & Touche LLP will be present at the annual meeting and will be available to respond to appropriate questions. We do not anticipate that the representative will make a prepared statement at the annual meeting; however, he or she will be free to do so if he or she chooses.
The board of directors recommends a vote “for” the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2018.2023.
Ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 20182023 requires the affirmative vote of a majority of our common stock present in person or represented by proxy at the annual meeting and entitled to vote on the proposal. Abstentions will count as votes against this proposal.
Annual Evaluation and Selection of Deloitte & Touche LLP
The audit committee annually evaluates the performance of its independent registered public accounting firm, including the senior audit engagement team, and determines whether to re-engage the current independent accounting firm or consider other firms. Factors considered by the audit committee in deciding whether to retain the current independent accounting firm include:
•    Deloitte & Touche LLP’s capabilities considering the complexity of our business and the resulting demands placed on Deloitte & Touche LLP in terms of technical expertise and knowledge of our industry and business;
•    the quality and candor of Deloitte & Touche LLP’s communications with the audit committee and management;
•    Deloitte & Touche LLP’s independence;
•    the quality and efficiency of the services provided by Deloitte & Touche LLP, including input from management on Deloitte & Touche LLP’s performance and how effectively Deloitte & Touche LLP demonstrated its independent judgment, objectivity, and professional skepticism;
the workload capacity and resources of Deloitte & Touche LLP’s senior audit engagement team;
•    external data on audit quality and performance, including recent Public Company Accounting Oversight Board reports on Deloitte & Touche LLP and its peer firms; and
•    the appropriateness of Deloitte & Touche LLP’s fees, tenure as our independent auditor, including the benefits of a longer tenure, and the controls and processes in place that help ensure Deloitte & Touche LLP’s continued independence.

Proxy Statement

In accordance with rules applicable to mandatory partner rotation, Deloitte & Touche LLP’s lead engagement partner for our audit was changed in 2022. The audit committee also oversees the process for, and ultimately approves, the selection of our independent registered public accounting firm’s lead engagement partner at the five-year mandatory rotation period. Prior to the mandatory rotation period in 2017, at the audit committee’s instruction, Deloitte & Touche LLP selected candidates to be considered for the lead engagement partner role, who were then interviewed by members of our company’s senior management. After considering the candidates recommended by Deloitte & Touche LLP, senior management made a recommendation to the audit committee regarding the new engagement partner. After discussing the qualifications of the proposed lead engagement partner with the current lead engagement partner, the audit committee chair interviewed the leading candidate, and the audit committee then considered the appointment and voted as an audit committee on the selection. The change in lead engagement partner after the current five-year rotation period occurred in February 2017.

Discretionary Voting Authority


If you complete and submit your proxy voting instructions, the individuals named as proxies will follow your instructions. If you are a stockholder of record and you submit proxy voting instructions but do not direct how to vote on each item, the individuals named as proxies will vote as the board recommends on each proposal. The individuals named as proxies will vote on any other matters properly presented at the annual meeting in accordance with their discretion. Our bylaws set forth requirements for advance notice of any nominations or agenda items to be brought up for voting at the annual meeting, and we have not received timely notice of any such matters, other than the items from the board of directors described in this Proxy Statement.
Voting StandardsA majority of outstanding shares of stock entitled to vote must be present in person or represented by proxy to hold the meeting. Abstentions and broker non-votes are counted for purposes of determining whether a quorum is present at the annual meeting.
A majority of votes cast is required to elect a director in an uncontested election. A majority of votes cast means the number of votes cast “for” a director’s election must exceed the number of votes cast “against” the director’s election. “Abstentions” and “broker non-votes” do not count as votes cast “for” or “against” the director’s election. In a contested election, which is an election in which the number of nominees for director exceeds the number of directors to be elected, directors will be elected by a plurality of the votes cast.
Approval of each of the other matters on the agenda requires the affirmative vote of a majority of the shares of common stock present or represented by proxy during the meeting. For each of these proposals, abstentions have the same effect as “against” votes. If you are a beneficial holder and do not provide specific voting instruction to your broker, the organization that holds your shares will not be authorized to vote your shares, which would result in “brokerbroker non-votes, on proposals other than the ratification of the selection of our independent registered public accounting firm for 2018. Abstentions and broker non-votes are counted for purposes of determining whether a quorum is present at the annual meeting.2023.
The following chart describes the proposals to be considered at the annual meeting, the vote required to elect directors and to adopt each other proposal, and the manner in which votes will be counted:
