I would now like to turn the conference over to Jason Vollmer, Vice President and Chief Financial Officer of MDU Resources Group. Thank you, Mr. Vollmer. You may begin your conference.
Thank you. Welcome everyone to our second quarter 2021 earnings conference call. You can find our earnings release and materials for this call on our website at www.mdu.com under the investors tab. Leading our quarterly earnings discussion today are Dave Goodin, President and CEO of MDU Resources, and myself. On the line to answer any questions you may have following our presentations are Dave Barney, President and CEO of Knife River Corporation, Jeff Thiede, President and CEO of MDU Construction Services Group, Nicole Kivisto, President and CEO of our Utility Group, Trevor Hastings, President and CEO of WBI Energy, and Stephanie Barth, Vice President, Chief Accounting Officer, and Controller of MDU Resources. During today's discussion, including responses to a question, some comments may contain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934.
Although the company believes that its expectations and beliefs are based on reasonable assumptions, actual results may differ materially. For a discussion of factors that may cause actual results to differ, we direct you to our earnings release and to Item 1A, Risk Factors, in our most recent Form 10-K and 10-Q. For second quarter of 2021, we delivered earnings of $100.2 million, or $0.50 per share, compared to second quarter 2020 earnings of $99.7 million, or also $0.50 per share. During the quarter, our results were impacted by higher stock-based compensation and healthcare costs of approximately $4.2 million after tax. Further impacting our second quarter consolidated results was a $5.4 million lower investment returns on certain benefit plans compared to the same quarter in 2020.
While these items had an impact on the quarter's results, all of our operations performed very well throughout the first six months of the year, growing consolidated revenues by 3.5% and increasing earnings $27.5 million year- to- date. Our utility business earned $9.6 million for the second quarter compared to earnings of $11.2 million in the second quarter of 2020. For the electric utility segment, reported earnings of $10.3 million for the quarter compared to $12.2 million for the same period in 2020. Higher operation and maintenance expense, largely the result of higher labor-related costs, including the increased stock-based compensation expense and healthcare costs as we previously discussed, as well as increased generating station expenses, drove the decrease in earnings. Lower benefit plan investment returns also negatively impacted the results. Partially offsetting the decrease was higher adjusted gross margin driven by a 6.9% increase in retail sales volumes.
Sales volumes increased for industrial and commercial customers during the quarter and were offset in part by lower residential volumes as the impacts of the COVID-19 pandemic start to reverse and individuals are returning to work as businesses reopen. Higher demand revenues and higher revenues associated with transmission interconnect projects also had a positive impact on the adjusted gross margin. Our natural gas utility segment reported a seasonal loss of $700,000, improved from a seasonal loss of $1 million for the same period in 2020. Adjusted gross margin increased during the quarter from approved rate recovery and 2% customer growth. Transportation revenues also increased from higher volumes transported to the company's electric generation customers. Partially offsetting the decreased loss was higher operation and maintenance expense, primarily labor-related costs as previously discussed, as well as lower returns on certain benefit plan investments.
The pipeline business had earnings of $9.2 million in the second quarter compared to $9 million in the second quarter of 2020. Higher non-regulated project revenues and increased allowance for funds used during construction were the primary drivers of the increase in earnings. Partially offsetting this was higher operation and maintenance expense relating to the previously mentioned increase in non-regulated projects, as well as higher payroll. Turning to the construction businesses. Construction services reported record second quarter earnings of $28.9 million compared to the prior year's record of $27.9 million. Revenues increased 6% on a year-over-year basis to a second quarter record of $525.6 million. Demand for construction services remains high for both the inside and outside specialty contracting. Inside specialty contracting saw strong demand for commercial and industrial work, specifically in the manufacturing industry, and outside contracting workloads increased with high demand from the utility industry.
Lower depreciation, depletion, and amortization expense, resulting from decreased intangible amortization related to prior acquisitions, also contributed to the increase in earnings. Our construction materials business reported second quarter earnings of $51.4 million, compared to the prior year's $53 million in the second quarter. Revenues increased 2% to $633.8 million. The decrease in earnings was primarily the result of higher selling, general, and administrative expenses from increased labor-related costs, as we had previously discussed. Lower returns on certain benefit plans also impacted the quarter. Partially offsetting these items was lower interest expense due to lower average interest rates. That summarizes the financial highlights for the quarter. Now I'll turn the call over to Dave for his formal remarks. Dave?
Great, thank you, Jason, and thanks to those of you listening in and spending some time with us today and for your continued interest in MDU Resources. Today, I will walk through each of our business lines to highlight some notable drivers in the quarter and go into greater detail about some of the organic growth items covered in yesterday's news release. Starting with our regulated energy delivery platform, we now have approximately 1.15 million customers across our electric and natural gas utility businesses, and our utility employees remain focused on organic growth and infrastructure improvements that help to safely and efficiently serve our customers. We continue to expect strong customer growth across our service territory, outpacing the national average and in the range between 1% and 2% compounded annually.
The electric utility finished the pre-commissioning, decommissioning activities on the coal-fired unit one at the Lewis and Clark Generating Station here in the second quarter and commenced decommissioning here in July. We expect to retire units one and two at Heskett Station near Mandan, North Dakota, early next year, which are the last of the company's wholly owned coal-fired facilities. Our generation portfolio in regards to nameplate capacity prior to the commencement of these retirements was 48% coal and will decrease to 31% in 2023 upon completion of the proposed Heskett 4 natural gas-fired peaking unit. Our natural gas utility, along with our pipeline business, WBI Energy, recently announced a project that will increase natural gas service to Wahpeton, North Dakota, while also being able to offer natural gas service for the first time to Kindred, North Dakota.
This project is driven by customer contracts requiring more firm natural gas supply than our current infrastructure can provide to eastern North Dakota. The project involves constructing approximately 60 miles of 12-inch pipeline from our existing facilities at Mapleton, North Dakota, to Wahpeton. It will add 20,000,000 cu ft per day of natural gas capacity and is expected to cost approximately $75 million. Depending on regulatory approvals, construction is expected to begin in early 2024 with a completion date later that year. Speaking of our pipeline business, we're excited that in early July, WBI Energy received final FERC approval, allowing construction to begin on the North Bakken Expansion project in western North Dakota.
This $260 million project will add 250,000,000 cu ft of daily natural gas transportation capacity to our system, bringing WBI's total pipeline capacity to more than 2.4 BCF per day while helping to reduce natural gas flaring in the region and allowing Bakken producers to move natural gas to market. With favorable weather during the construction season, we expect the project to be in service by end of this year. Moving on to construction. Our Construction Services Group had an outstanding second quarter as demand for both inside and outside specialty contracting remains very strong. CSG reported record second-quarter revenues and earnings and an all-time record backlog, now standing at $1.32 billion as of the end of June.
Bidding remains highly competitive in all areas, but we are confident that our relationships with existing customers, our skilled workforce, and our high quality of service will aid in securing and executing on profitable projects. As a reminder, revenue guidance at this business for 2021 continues to be in the range of $2.1 billion-$2.3 billion, with margins comparable to or slightly higher than 2020 levels. Finally, at our construction materials business, while earnings were down slightly year-over-year, Knife River is operating at near record levels, falling just short of the prior year's record second-quarter earnings while continuing to produce record revenues. Demand and pricing for aggregates and ready-mix concrete is strong across a number of markets. Construction materials reported backlog at the end of the quarter at $912 million, an increase of over 4% from the prior year.
Revenue guidance for this business is also in the range of $2.1 billion-$2.3 billion, with margins comparable to our 2020 levels. We remain optimistic about our construction businesses and continue to evaluate strategic acquisition opportunities that will enhance our existing footprint and appropriately expand our business, all while earning attractive returns on invested capital. As mentioned in our news release yesterday, we feel very positive about the conversation surrounding infrastructure funding packages at the federal level, as well as at various state levels across our footprint. With combined construction backlog at an all-time record at $2.23 billion as of June 30th, we believe we're well positioned to take advantage of these multi-year growth opportunities. While we believe these infrastructure proposals will provide additional opportunities to some of our core areas of business, such as surface transportation improvements, renewable energy, power grid modernization, broadband, and much more.
These infrastructure proposals are not included in our earnings per share guidance of $2- $2.15 for this year of 2021, or in our five-year capital investment plan for that matter as well. Overall, we are very pleased with our performance throughout the first half of the year. Our focus at MDU Resources has been, and continues to be, to produce significant long-term value as we execute on our business plans, our organic growth projects, and our targeted acquisitions. We continue to maintain a strong balance sheet, solid credit ratings, and a good liquidity position. For the last 83 consecutive years, we provided a competitive dividend for our shareholders and have been increasing it for the last 30 years.
As always, MDU Resources is committed to operating with integrity and a focus on safety while creating superior shareholder value, and we continue to act along our tagline of Building a Strong America. With that, operator, we'll open it up for questions.
At this time, I would like to remind everyone, if you would like to ask a question, please press star and then the number one on your telephone keypad. If you would like to withdraw your question, press the pound key on your telephone keypad. If you are on a speakerphone, please pick up your handset before entering your request. We will pause for just a moment to compile the Q&A roster. Your first question comes from the line of Chris Ellinghaus with Siebert Williams Shank.
Hey, everybody. How are you?
Hi, Chris. Good afternoon.
Good afternoon, sir. Can the guys sort of just talk about what the construction season in the second quarter looked like and how's it shaping up in July so far?
Sure, Chris. Maybe we'll start with Jeff Thiede at Construction Services, coming off the record second quarter that they just posted. Go ahead, Jeff.
All right. Thanks for the question, Chris. Our bidding opportunities are strong in all of our markets, and there continues to be demand for our services that we provide. That's demonstrated, of course, by our Q2 record backlog that Dave had mentioned. We've always operated in these competitive markets, and we secure many of our project awards based upon a price and non-price criteria for best value. That helps us continue to perform at good margins. Some of our markets have experienced some increased competition. However, the strength of people and attention to meeting or exceeding our expectations in safety and production and quality have resulted in strong backlog and performance through Q2 this year. We are seeing some projects, large projects, get completed. We are still seeing good bidding opportunities going forward.
And-
Thank you, Jeff. Go ahead.
I just wanted to ask.
Go ahead, Chris
how weather was for the construction season. Was it favorable?
I think it's favorable.
Jeff?
Yes.
Okay.
Absolutely. Yes.
Chris, shall we turn to Dave Barney?
Sure.
Yeah.
Dave, you want to talk about the second quarter just a bit, and certainly highlight the $912 million you have in backlog here at the end of the second quarter?
Well, I think you did that, Dave. Yeah, our backlog is strong. Going into the next two quarters, we're happy where we're at with our backlog. Margins are very strong for us and continue to grow. We've had some definitely increases in products. We've been able to pass along. The second quarter was a great quarter. Year-over-year, our margins on all materials are up. We expect that to continue throughout the year. July, we did have some hot weather, some days out there that were over 100 degrees. It slowed us down a little bit. We believe July and the rest of the year is still gonna be strong for us.
Okay. For the two construction businesses, have you guys evaluated where the infrastructure bill stands today? Have you got any thoughts on how that might impact you? Sort of as an aside question, you're already pretty well strained in terms of construction capacity. How do you envision an influx of infrastructure projects over the next couple of years influence margins and labor capacity and things like that?
Chris, I'll start, and then both Dave and Jeff can give a little maybe detail with their respective businesses. As we've reviewed the current infrastructure package that's under debate in the Senate. On the incremental new dollars associated with that, and if you look at the large buckets, whether it be transportation, roads, bridges, kind of traditional transportation, highway infrastructure, broadband. There's some EV dollars in there for EV network. You've also got, I'll say, power delivery, energy delivery upgrades, some renewables. You take those buckets, and of the total, roughly two-thirds of the dollars within that infrastructure plan fit right in the wheelhouse of what we do between our materials and services business.
Again, that's broad-based, but when we look at the big buckets, we get quite excited in the fact that those are new dollars flowing into industries that we perform, and I think we perform very well. Obviously, the devil's in the details and what the final bill is produced and back over in the House and through conference committee, et cetera. Certainly, what indicates today is it's a lot of what we do today. That might be a suffice answer for you at the moment, but I think you also wondered about how we would handle the additional work and workload opportunities at each of services and materials. Maybe for that, I'll kick it over to Jeff. Jeff, can you kind of touch on that in light of, again, we see this beyond 2021.
This is 2022 and beyond, I mean, from a timing perspective, but just maybe help Chris out with some of your thinking.
Okay. We've been able to retain our workforce during the second quarter, and we've been doing that by focusing on retaining, training, and attracting industry top talent. Our commitment to safety and treating people with respect and working together as a team, especially during the last year and a half through COVID-19. Given our backlog, we're seeing some challenges with available qualified labor, mostly in our outside transmission or distribution work, which we think will be benefiting from the infrastructure bill. Our inside group has some similar challenge with qualified labor, but our recruitment and training efforts continue, and we're very proactive in our respective markets and also industry on recruiting in high schools and STEM programs, women in trades, minority, and college groups.
We've been able to recruit the workforce needed to keep up with the demand and to build out our backlog safely, productively, and timely, and of course, always with quality.
Maybe following on, Dave Barney in the materials area?
Yeah, Chris. Our employee count is about where it was last year. We are definitely focused on the retaining and recruiting employees. We are in the process of building a world-class training center right now in Oregon for all of our companies and not just Knife River for the industry. We think that will definitely help us going forward in the future. It's something we're focused on and we'll continue to focus on. We definitely think if this infrastructure bill gets passed, we will see increase in bidding opportunities. With that, we expect our margins to continue to go up also.
Okay, great. Thanks for the details, guys. I appreciate it.
Thank you, Chris. Appreciate the questions.
Your next question comes from the line of Brian Russo with Sidoti.
Yeah, Hi. Good afternoon.
Hi, Brian. Good afternoon to you.
Hey, I know you touched upon possibly labor issues as an industry as a whole and raw material inflation. There was a large construction material peer the other day that reported, and they noted that higher prices for diesel and liquid asphalt were impacting their margins. I'm wondering, how are you countering that, generally speaking? Could you just maybe get a little bit more granular on your cost inputs and how you're managing what seems to be an industry-wide issue impacting some companies more or less than others?
Yep. Sure. The question, Brian, is more particular on the material side, and you said, for example, others have noted diesel and liquid asphalt as two of the drivers. I'll ask Dave Barney to address what he's seeing in his business so far as inflationary pressures and commodity price, like the items that you noted. Dave?
Yeah, Brian Russo. We definitely are seeing diesel prices continue to increase. It is a concern going forward. Like I've said before, we continue to push our margins up on our aggregates, the ready-mix, even on our construction side. We have seen our AC oil pricing come down from last year. We've been able to pretty much hold our margins on that. We've lost a little bit on margins in some of our jobs, Most of our jobs, we continue to increase those prices.
Okay, great. I think, maybe it's on the services side, you mentioned strength in manufacturing. Could you just be more specific, what sub-markets of manufacturing you're seeing that strength?
Certainly.
Sure. Jeff?
Okay.
No, go ahead, Jeff.
Okay. Sorry about that. Manufacturing encompasses the productions of goods and services with confidential clients. That really sounds like a non-answer. However, we're bound by our confidentiality agreements with these clients. What I can share is that we've been asked to enter a new geographic market with a satellite office for two of our clients to serve them for another large build that's just getting started. We're expanding in this part of the country, leveraging our performance on large, medium, and small projects that we've successfully completed and are completing for nearly three decades of this client that we've had.
Okay, great. Is your construction services business and/or the materials side involved in undergrounding of transmission and distribution?
We are.
Yep. Jeff?
Yes. If you're talking about what's been published by Pacific Gas and Electric, that's one of our largest customers, that is an area of work that is right in our wheelhouse. We're doing distribution and transmission for this client, we also do underground work. Combined with our expertise in the market that we're serving for PG&E, plus adding to that with some of our sister companies, we see that as a great opportunity to serve our client in this area.
Okay, great. Just on the pipeline side, the $75 million expansion project, I'm just curious, why is construction not until 2024?
Yep. Yeah, Brian, I'll just touch on that. Trevor's here to give you more details. Really that's the timing to go through the full regulatory process, the full siting. We just kind of went through this process preceding our North Bakken Expansion project. We've got a pretty good feel for that. Anything, Trevor, to add to that?
That's it.
Okay.
Okay, understood. It sounds like that's kind of an organic growth opportunity for the pipeline segment. Can you quantify or put some numbers behind the size of that opportunity for expansion?
Sure. This is Trevor. At this point, we haven't disclosed any of the financial numbers around it. We're in the front-end work getting ready for the pre-filing process that Dave referenced later this fall. If you take the $75 million capital budget, our FERC capital structure is 60% equity and apply a FERC return, you get in the wheelhouse of kind of what the earnings impact of the project could be.
Right. Okay, got it. When can we expect the IRP to be filed at the electric utility?
Certainly Nicole can touch on that. That was actually filed here just recently, midyear. Nicole, any more details on the IRP?
Nope, you hit it, Dave. Yeah, we filed that in the state of North Dakota here in July.
Okay, then just lastly, both electric and gas utility, could you just update us on your regulatory strategy? Do you have any plans to file any rate cases in any of your jurisdictions?
Yeah, certainly. As you're most likely aware, we monitor this on a very regular basis. What we're looking at right now as we look ahead is just probably some evaluation around our electric segment in terms of timing of those rate cases. Again, we haven't made any final decisions there, but are evaluating timing on a few states on the electric side of our business. We just recently implemented final rates for several jurisdictions on the gas side of the business, North Dakota, Montana, and Minnesota. The last one that I would touch on is in the state of Washington. Following the outcome we just had, we are currently contemplating a limited issue case to recover some of the 2020 plant additions as well as 2021 wage increases. That would be top of the wave, some of the key activities we're focused on right now.
Okay. Thank you very much.
Thank you for the questions, Brian.
Your last question comes from the line of Ryan Levine with Citi.
Hi, good afternoon.
Hi, Ryan. Good afternoon to you as well.
Hey, Dave. What's the status of the North Bakken Expansion conversations for additional customers, and what's the capacity with compression that's still available for sale?
Hey, Ryan, this is Trevor. As we always do, we're in kind of constant contact with customers out in the Bakken. Gas production in the Bakken is really almost back near to its peak. I think it's 95% of its peak production, even though oil's only at 74% of its peak. We're seeing gas-oil ratios in the field
Continue to increase. I think they're up 80% over the last five years. The North Dakota Pipeline Authority, Justin Kringstad, has a new slide deck out where he talks to this, and in his outlook, continues to stress the need for, or the expectation for needing additional gas processing, NGL takeaway, as well as natural gas pipeline capacity takeaway. With that, our North Bakken pipe is strategically located right through the heart of the Bakken, kind of north to south of Lake Sakakawea, interconnecting with Northern Border. We think we're well-situated as the Bakken continues to regain its footing in terms of drilling and production, and we'll be able to really be a good opportunity for our customers in that area. In terms of expansion, the project is readily expandable with compression.
There's a lot of variables that go into how much additional, but it could be in the range of 600,000 Mcf a day of potential total capacity. Right now, we're contracted. When we get to full year volumes, it'll be 245,000.
Thanks. One for probably Nicole. It seems like the electric load was pretty strong this quarter. Wondering how much of that was weather related and versus more organic volume growth? As you look at your planning forecast through 2030, what's embedded in that from an EV or transportation demand for electricity, and how does that compare with some of the federal announcements this morning for 50% new vehicle electric sales by 2030?
Okay. Thanks for the question. I'll start with the volumes, really. When you look at the quarter, what we saw, I would characterize more as a getting back to post-pandemic levels. What we saw really was, as was mentioned, an increase on our commercial industrial side, and that was offset by actually lower volumes on the residential side for the quarter. I will acknowledge, as most people are aware with the heat waves we've seen in our territory in June, we did see higher residential. When you look at the quarter in total, really, it was driven by higher volumes industrial commercial, and we feel that was largely driven by kind of, again, the post-pandemic, in terms of businesses reopening and getting back to full volume there.
We look ahead here in July, obviously on the residential side, we have continued to see pretty good volumes relative to what I would characterize as weather now. Back to the is it weather, is it post-pandemic? I would say as we look to July, we haven't finalized all this, we are seeing probably some increased volumes due to weather in that month. Your next question relates to, as we look at our forecasting for our electric demand going forward, we have not really, at this point, baked in any significant EV transition. We haven't seen the same level of penetration in our electric markets that has been happening in other areas of the country.
As of this point in time, I would say that it's really not a significant piece of the overall increase in our demand that we're disclosing in the 10-K, as an example. I believe I've covered your questions, but any follow-up?
Yeah, appreciate that. In terms of larger transmission projects in the out years, is there any projects that could potentially be advanced due to the broader mandates or federal policy discussions that are being had?
Yeah. You bring up a very good point. We are currently, I was just last week in a meeting with our regional transmission organization, which is MISO, as you know, they have done several modeling efforts on what the future looks like in terms of scenario planning around individual companies' goals on the renewable focus and decarbonization, as well as what could happen as we think about this more broadly federally. Certainly, transmission is a significant investment as we look forward. In fact, one of their planning scenarios would've called for, again, this is just within the MISO market, again, this isn't covering the U.S., additional build-out of $100 billion. Again, there's multiple scenarios here, just to level set, that's one example of the amount of transmission that's needed to meet some of these proposed goals out there.
First the question is, can all that be done within the timeframe? Secondly, the question is, what happens with affordability and that sort of thing? As we look ahead, transmission upgrades, there certainly will be a lot of opportunity there. What we're looking ahead to is how do you get those permitted, constructed, and operating? These are, again, within the MISO footprint. This isn't necessarily our company specifically here, so it's more of a broader look. To get to the question of is there opportunity in transmission going forward, there certainly is.
Last on the utilities front, do you have any ROFOs or ROFRs related to any of the build that's incorporated in MISO? I guess one on construction service, can you speak to some of the cost pressures you're seeing?
Okay. Can you repeat the question?
Do you have any right of first offer or right of first refusal on developing any of the transmission that may be developed in MISO, within the broader, within your footprint?
I guess how I would respond to that is it depends on how they decide to move forward. As an example, we were involved in a multi-value project. Previously, it was the Big Stone South to Ellendale project, where we then have a FERC transmission facility that's not directly allocated to our customers through state regulation. That would be one example of an opportunity that came out of a multi-value project within the MISO market.
Thank you.
Yep. Ryan, your second part of that was relative to services, maybe you could repeat the question so I make sure Jeff gets it.
If he could press star one-
Ryan, are you still there? Okay. Very good. Maybe we got Ryan's question answered. Back to you, operator. Oh, here comes Ryan.
Yeah, I think I got disconnected. In terms of the margin pressures being in construction service, something you could elaborate on some of the drivers of the cost pressures?
Jeff, could you take that one?
Yes. We think about steel and copper and aluminum and PVC and fuel, and those have risen sharply over the past six - nine months. We've also had some impacts with electronic components that are part of most of the materials we supply. Of course, our vehicles, which have had some availability delays. Our teams have been proactive in notifying our customers, while also working with our suppliers to mitigate the impact and mitigating our impact to backlog margins. We've had success in anticipating these increases and availability issues. We've also used our purchasing power and our financial strength to bulk purchase some commodities in some of our markets where it makes sense, where we can collaborate, get our customers involved, and take the risk off the table in procuring in advance.
Great, thank you.
Yeah, Ryan, just as a top level there, again, we reiterated on our guidance, margins comparable to actually slightly increasing in services. I think that gives you an overall direction with regards to margins. Very good. Back to you, operator.
At this time, there are no further questions. I would now like to turn the conference back over to management for closing remarks.
Well, thank you all for taking the time to join us here on our second quarter earnings call. We're certainly pleased with the results of the first half of the year, and we look forward to a continued strong performance throughout the remainder of 2021. As such, we are affirming our earnings per share guidance in the range of $2-$2.15 for 2021. We appreciate your continued interest in and strong support of MDU Resources as we continue to building a strong America. So with that, I'll turn it back to the operator.
This concludes today's MDU Resources Group conference call. Thank you for your participation. You may now disconnect.
