Mdu Resources Group Inc Q2 FY2023 Earnings Call

Hello, my name is Lynette, and I will be your conference facilitator. At this time, I’d like to welcome everyone to the MDU Resources Group 2023 Second Quarter Conference Call. The webcast can be accessed at www.mdu.com under the Investor Relations heading, select Events & Presentation and click Q2 2023 earnings conference call. After the conclusion of the webcast, a replay will be available at the same location. I would now like to turn the conference over to Jason Vollmer, Vice President, Chief Financial Officer and Treasurer of MDU Resources Group. Please go ahead, sir.

Thank you, Lynette. And welcome everyone to our second quarter 2023 earnings conference call. You can find our earnings release and supplemental materials for this call on our website at www.mdu.com under the Investor Relations tab. Leading today’s discussion along with myself will be Dave Goodin, President and CEO of MDU Resources. Also with us today to answer questions following our prepared remarks will be Stephanie Barth, Vice President, Chief Accounting Officer, and Controller of MDU Resources; Nicole Kivisto, President and CEO of our Utility Group; Rob Johnson, President of WBI Energy; and Jeff Thiede, President and CEO of MDU Construction Services Group. During our call, we will make certain 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 more information about the risks and uncertainties that could cause our actual results to vary from any forward-looking statements, please refer to our most recent SEC filings. We may also refer to certain non-GAAP information. For a reconciliation of any non-GAAP information to the appropriate GAAP metric, please reference the earnings news release. I will provide consolidated financial results for the first quarter before handing the call over to Dave for his formal comments and forward-look. This morning, we announced second quarter earnings of $130.7 million or $0.64 per share on a GAAP basis compared to second quarter 2022 GAAP earnings of $70.7 million or $0.35 per share. Second quarter income from continuing operations was $147.6 million or $0.72 per share. It's important to note that with the spin-off of Knife River being completed during the quarter, Knife River's results and other related impacts are reported as discontinued operations in our GAAP-based results for the current and prior year. As such, with the completion of the spin-off and work continuing with the tax advantage separation of our construction services business, we are also reporting adjusted income from continuing operations to provide financial results that more closely correlate to and better outline the strength of our ongoing business operations. These adjustments reflect the May 31st spin-off of approximately 90% of the outstanding shares of Knife River Corporation, including the unrealized gain on the retained shares, as well as any other items related to our strategic initiatives. For more information on these adjustments, please see the table provided on Page 7 of our earnings news release. We experienced outstanding results from our businesses in the second quarter with adjusted income from continuing operations of $60 million or $0.29 per share compared to second quarter 2022 adjusted income from continuing operations of $36.1 million or $0.18 per share. As we look at the individual businesses, our combined utility business reported earnings of $13.1 million for the quarter compared to a loss of $2.9 million in the second quarter of 2022. The electric utility reported second quarter earnings of $16.3 million compared to $4.6 million for the same period in 2022. The increase was largely the result of higher retail sales due to interim rate relief in North Dakota and Montana and a 31.4% increase in commercial and residential volumes. The volume increase is primarily the result of warmer weather and an electric service agreement to provide power to a data center near Ellendale, North Dakota. Also driving the increase in earnings was lower operation and maintenance expense largely related to the absence of a prior year planned maintenance outage at one of our generating stations and lower payroll-related costs. This business also experienced higher investment returns on non-qualified benefit plans. Our natural gas utility reported a seasonal loss of $3.2 million in the second quarter compared to a loss of $7.5 million in the second quarter of 2022. Revenues increased primarily from higher basic service charges and approved rate relief in Washington and Idaho. The business also benefited from increased investment returns on non-qualified benefit plans during the quarter. Warmer spring weather led to a 12.5% decrease in retail sales volumes to all customer classes during the quarter, which was partially offset by weather normalization and decoupling mechanisms. Increased operation and maintenance expense, primarily higher payroll-related costs, as well as higher interest expenses added to the seasonal loss, which was partially offset by increased interest income associated with higher purchased gas cost adjustment balances. The pipeline business earned $8.7 million in the second quarter compared to $7.1 million from this time last year. The improvement in earnings was driven by higher transportation and storage-related revenues. This business experienced record quarterly transportation volume largely due to the increased contracted volume commitments from the North Bakken expansion project. The pipeline business also benefited from non-regulated project revenue and increased investment returns on non-qualified benefit plans during the quarter. The increase was partially offset by higher operation and maintenance expense, primarily due to higher payroll-related costs and non-regulated project costs. In addition, interest expense increased as a result of higher interest rates and higher debt balances. Construction services reported record second quarter revenue of $747 million and record second quarter earnings of $38.6 million compared to revenue of $685.4 million and earnings of $34.5 million for the same period in 2022. EBITDA increased $10.6 million in the second quarter compared to the prior year. Commercial utility, industrial, and institutional workloads all increased for the quarter, which drove the record second quarter revenue. Gross profit increased largely due to product mix in the commercial, industrial, and institutional markets, offset in part by lower renewable project revenue and gross profit. This business also saw higher selling, general, and administrative costs, largely higher payroll-related costs and interest expense from increased working capital needs and higher interest rates. As I mentioned, results at each of our businesses were positively impacted in the second quarter on a non-cash basis by higher investment returns on non-qualified benefit plans. Collectively, the positive earnings variance was approximately $8.4 million or $0.04 per share when compared to the second quarter of 2022. This change in investment returns is due to fluctuations in the financial markets. That summarizes the financial highlights for the quarter. And now I'll turn the call over to Dave for his formal remarks.

Well, thank you, Jason. And thank you everyone for spending time with us today and for your continued interest in MDU Resources. This second quarter was historic for our company as we completed the separation of Knife River Corporation on May 31st and experienced outstanding performance from all of our remaining businesses during the quarter. The Knife River separation was a monumental achievement for both our company and Knife River. And to add record results across our remaining businesses during the quarter makes me extremely proud of and grateful for our hardworking and dedicated employees. Our utility and natural gas pipeline businesses continued to perform well. The utility was positively impacted by rate relief and higher electric retail sales volumes during the quarter. The pipeline business had record quarterly transportation volumes as we continue to see the benefit of increased contracted volume commitments, particularly on our North Bakken expansion project. Construction services had record second quarter revenues, second quarter earnings and second quarter EBITDA, all driven by increased workloads and increased gross profit. While completing this record amount of work, construction services continues to see strong demand and secured additional projects to replace its completed and nearly completed projects, ending the quarter with record second quarter backlog. To summarize activity by business segment, I'll start off with the regulated energy delivery businesses. The utility reported increased earnings on a combined basis for the quarter, driven by rate relief in certain electric and natural gas jurisdictions. Electric retail sales were 31.4% higher, which was due in part to warmer temperatures that increased customer usage but also due to bringing on a new large volume customer during the quarter. We expect our Heskett Unit 4 to be operational here later this year as we finish construction on the 88 megawatt natural gas-fired generating facility located just across the river in North Mandan. We also continue to expect rate-based growth to grow between 6% and 7% compounded annually over the next five years, driven primarily by investments in system infrastructure, upgrades, and replacements to safely meet customer demand. We have received approvals on settlements in North Dakota Electric and Idaho natural gas rate cases with new rates effective July 1st in both cases, and we filed an all-party settlement in the Montana Electric case as well. Our utility continues to seek timely regulatory recovery for the investments associated with providing safe and reliable natural gas and electric service to our growing customer base, as we expect to file three additional general rate cases yet this year and one more in early 2024. Our pipeline business performed very well during the quarter. As Jason noted, this business recorded higher transportation and storage related revenues during the quarter and had record quarterly natural gas transportation volumes. In January of 2023, WBI Energy filed a general rate case with the Federal Energy Regulatory Commission for increases in its transportation and storage service rates. These rates take effect on August 1st, subject to refund in the event of a rate case settlement agreement, of which the company is in active discussions with the FERC and its customers about the rates outlined in the settlement agreement that would take effect in August of 2023. We began construction in the second quarter on three natural gas pipeline expansion projects that are anticipated to be in service in 2023 as well. These projects will add approximately 300 million cubic feet per day of incremental capacity, increasing the total system capacity from 2.4 billion to 2.7 billion cubic feet per day. With a strong start to the year for our regulated energy delivery business, we are increasing earnings guidance for the regulated businesses to now a range of $150 million to $160 million, up $10 million from our previous range of $140 million to $150 million. Now I'd like to move on to our construction services business. As I mentioned previously, demand remained strong for our construction business services, evidenced by our record second quarter revenue, earnings and EBITDA along with our backlog. We're well-positioned to complete these projects safely and efficiently with our ability to attract and retain a skilled workforce of 8,500 employees across our 40-plus state footprint. We are affirming our 2023 revenue guidance to be in the range of $2.8 billion to $3 billion and we expect slightly higher margins compared to 2022, and EBITDA in the range between $200 million to $225 million. On July 10th, we announced that our Board of Directors determined that we'll pursue a potential tax-advantage separation of our construction services business. After an extensive strategic review, the Board determined that this was the best path forward to optimize value for shareholders while achieving our objective of becoming a pure play regulated company. We are focused on determining the best method and timeline to effect the separation and we'll keep you updated as we proceed. Looking forward, our construction services business is well-positioned to benefit from increased bidding opportunities as well. With the funding from the Infrastructure Investment and Jobs Act and the Inflation Reduction Act, our construction services business will see increased demand in 2023 and beyond for the work it already excels in. Overall, as we look ahead, we are encouraged by our opportunities for ongoing customer and system growth and our electric and natural gas utilities, our robust slate of pipeline expansion projects, and the steady demand for pipeline services along with the high demand we are seeing for construction services. We also announced today that the Board of Directors declared a quarterly dividend on the company's common stock of $0.125 per share. This change in dividend reflects our intent to align our payout relative to the regulated energy delivery earnings with pure play regulated peer companies. The dividend is payable October 1st to stockholders of record on September 14th. Along with this announcement, we established a new dividend payout ratio target of 60% to 70% of our regulated energy delivery earnings. We are proud of our 85-year history of returning capital to our shareholders through the dividend and feel this new target payout ratio will allow us to continue this practice while reinvesting in the growth of our regulated operations as we progress on our strategic path to becoming a pure play regulated company. As always, MDU Resources is committed to operating with integrity and with a focus on safety while creating superior shareholder value, as we continue providing essential products and services to our customers and communities while being a great and safe place to work. I appreciate your interest in and commitment to resources. And ask now that we open the line for further questions, turn it over to you, operator.

We'll take your first question from Dariusz Lozny from Bank of America.

Maybe just starting off on the CSG transaction. Can you discuss at all the specific methods or perhaps when you might be able to update the market as far as what you're considering and timeline for the transaction?

Certainly, Dariusz, I appreciate you calling in and certainly your question is top of mind for us here as well. I'll just maybe step back for a moment. Certainly, our main focus here is how do we optimize the value here for our shareholders. I think that is very central to our thinking. CSG is certainly a great performing business. It's evidenced again by the second quarter results that we just posted here. And when we think of the backlog at a record level even with record levels of revenue, we think it's performing very well. Certainly, as we think about that business, we've done recently a spin with our Knife River and that could be in that tax advantage category as well, but we're also looking at other alternatives. So far as the timeline is concerned, I would say there's been no final determination on the means of the tax advantage separation. Certainly, we will update you and the market as we go along. I just would remind you that we're going to be very diligent here, but I think we've also demonstrated our ability to do this kind of thing. And with that, I'll just stop there but we'll certainly update the market along the way.

Could you provide more details on the updated guidance range for the year? Specifically, can you explain the relative contributions to the higher guidance? It seems like there is a benefit from the non-qualified plan, the new large customer at the electric utility, and some positive developments on the regulatory front. Can you rank how each of these factors, or possibly others, contributed to the increased guidance?

I appreciate you noting that. Certainly, we're guiding up basically 7% if you think midpoint to midpoint from the prior range to the new range, if you just kind of quantify that. I would say the things you noted there are all contributory to that. Certainly, we've had favorable weather in the first part of the year. We saw that with strong winter volumes, if you will. And then we went quickly from winter to an extended late winter right into summer, which helped some of the electric volumes there. So we saw that. The large volume customer certainly is incremental to, as we think about the year, it's large volume, low margin, but at the same time additive. And certainly the regulatory activity that Nicole and her team have done with the completion, both North Dakota and Idaho and then an all-party settlement for Montana, those all have contributed in addition to Rob ramping up on North Bakken expansion, which we had expected frankly, year-over-year. So we're very pleased with the progress, hence raising the guidance for the back half. So I think you're spot on to quantify those; they all contributed, I would say.

One more if I can. Just wanted to ask about the segment level guidance for CSG specifically. You guys are pointing to interest expense of $16 million for the full year, and it looks like it's pretty modest for the first half of the year. Are you expecting to issue some debt at that segment in the second half of the year?

I'll ask Jason since this is a financing-related question. Just as a reminder, we raised our revenue guidance by $50 million at the end of the first quarter, and we're maintaining our forecast of 2.8 to 3.0 for the rest of the year, with margins expected to be slightly higher year-over-year. However, your question seems to focus more on interest expense and our thoughts on that, right? I want to ensure we address your inquiry correctly.

Yes, that's correct. The guidance implies an uptick in the second half of the year. So I was just wondering if there's implicit in that is an issuance of some incremental debt at that segment.

I can jump in there, Dariusz. Thank you. This is Jason. I think from our perspective as we look at this, I mean, we really are focused on the guidance range that we've put out there for revenue and the EBITDA side of things; that's really where we're putting most of our focus at. Obviously, with EBITDA, we reconcile back to an earnings number, which is probably where you're referencing some of those add-backs, I think, throughout that process. As we look at there's a range of outcomes there I think that we could see. We aren't looking specifically at any additional debt issuance there. What we have seen with CSG, as we mentioned, higher financing costs, higher interest expense, even here in the first quarter, is that working capital numbers have been a little bit higher with this business as we've seen the vast amount of work that they've been working through here and the increase in backlogs along the way. That combined with higher interest rates that we have seen have had an impact there as well. So really what we're kind of pointing to at this point is the expectation that we would see some of that persist here into the second half of the year. I won't get specific on interest cost itself. We really don't give guidance at that level. But there is some impact, I think as we look at just kind of the balances that we see here today.

Dariusz, maybe tied into that, but it's more of a question for you. Would you be interested in hearing from Jeff Thiede more operationally, how he's thinking about the business, particularly the back half of the year?

Certainly, that would be very helpful.

We're continuing to see strong demand for our services as reflected in our record Q2 backlog and that's also complemented by our record second quarter revenues and our record second quarter earnings. Our backlog is very broad-based but on the other hand, it's very diversified. We're building some of the most innovative and largest projects in multiple geographic regions across the country and the markets that we serve. Several of those projects, of course, in Las Vegas are headliner-type projects that are well underway, and there are more projects ahead on our radar for the future. You look at our T&D side and we have a lot of our service agreements, our MSAs that have been negotiated and renewed, reflected our updated labor, material, fuel, and equipment costs, that's going to be a contributing factor to our success going forward. In addition, we've got some exciting projects in our T&D sector. We're underway in Kansas City on a streetcar extension project and US 69 Expressway. So this illustrates our diversification as a company and how we're able to capitalize on current markets and pivot to expanding markets for continued success.

Your next question will come from the line of Chris Ellinghaus from Siebert Williams Shank.

The discontinued operations number, I'm really thinking from the other segment. I presume that’s all Knife River. Is there anything else included in that number?

Chris, I'm going to ask Stephanie Barth here, our Chief Accounting Officer to maybe walk through a little bit what's included there to help you and others. We know it's a noisy quarter when you think of that hence the discontinued operations and also the adjusted earnings on a year-over-year. So, Stephanie?

Chris, one thing to keep in mind is we only had Knife River’s operations for two months in 2023 here in the second quarter compared to three months last year. And then I would say the other large contributor there would be the separation cost, so some of the transaction-related costs that we incurred for professional advisors as it related to the transaction.

So the $14.1 million loss is purely Knife River operational, that doesn't include any Knife River specific transaction-related expenses?

No, that would actually include the Knife River transaction-related costs.

So that's operational plus their share of strategic initiatives…

Yes.

So you gave us the higher utility guidance. But given that Knife River has been spun off and that probably construction services is still around for certainly the vast majority of the year and through the heavy construction season, why did you decide not to do consolidated guidance at this point?

I believe this ties back to our earlier discussion about starting the year by focusing more specifically on each business. We aimed to provide guidance in light of the timing and uncertainty surrounding Knife River, which is now behind us. I also think it's beneficial for investors to have a more detailed understanding of each business as we consider their future. Furthermore, I want to emphasize that we envision ourselves as a pure play regulated business at some stage. Our recent dividend announcement aligns with a payout ratio typical of regulated pure play businesses. We still feel that the guidance reflects our forward-looking perspective on the business, which should be significant for investors as well. Jason, do you have anything you would like to add in response to Chris's question?

I would like to point out that we still hold a retained stake in Knife River as part of the organization. You'll notice in many of the disclosures, as Dave mentioned, this quarter was somewhat complicated. Throughout the year, we experienced some unrealized gains in that area. This is part of our continuing operations. Even though Knife River has been spun out, it will still fluctuate. Therefore, to arrive at a consolidated continuing operations figure, there are numerous variables to consider. We believe it is more beneficial to focus on segment-specific guidance, particularly regarding the regulated energy delivery and the services provided separately.

Dave, you mentioned the dividend. It seems likely that you will be at the lower end of the new payout target for 2024. Can you share your thoughts on how you expect the dividend growth to develop and how you foresee the payout changing over time?

No, spot on question, Chris. Providing a kind of a targeted or expected payout ratio that we just did here today is actually something new for us. I mean, thinking prior to our more diversified business model, we always kind of talked about our long rich history, which we reinforced today of 85 years. But certainly guiding folks towards actually starting in May, we put out a release that we'd expect our future dividends to reflect more of a pure play regulated business consistent with peers in that business. So I mean that's kind of the underpins. And then as we look to this 60% to 70% payout ratio, I hear your question; so how do we see that over time? I think that percentage ratio is appropriate. Certainly, that's based on earnings. And also, we would expect our earnings to, I think rate base growth would be a proxy, if you will, from an earnings on a year-over-year basis. So rate-based growth with proper regulatory timely recovery, the two should have a relationship, and so that would be my expectation. And then having said all that, it's obviously up to our Board every quarter as we get the dividend discussion and all these factors come into play. But that would be my expectation that it would have some replication of a proxy to basically rate-based growth.

And one more question for Jeff. Dave sort of touched on this about sort of expecting some pick-up in activity from the various legislation. What are you seeing on the clean energy side going forward, are you seeing incremental business? And is any of that really showing up in the backlog yet or is that sort of what's going to be a pretty sizable driver for you going forward?

I think more of a driver for us going forward. We haven't seen projects directly funded through the Infrastructure Investment and Jobs Act or the Inflation Reduction Act yet in backlog, but these opportunities are going to provide us a tailwind for the future. And we're very well positioned, Chris, to capture some of these projects due to our experience with this type of work and the services that we provide, highways, bridges, ports and airports and water systems. I mentioned the Kansas City Streetcar extension in the US 69 Expressway. Those are two projects we're really excited about. And we're going to build upon our recent project completion and opening of the Kansas City Airport, and our continued work at the Portland International Airport. And of course, our experience in the renewable space, whether it's electric vehicles, EV charging stations and solar work puts us in a good position for future projects in this area, contract awards, which is going to, of course, contribute to the momentum of our record Q2 backlog and earnings. We've got a great team, Chris, and we're well positioned and those types of projects are on our radar.

We'll hear next from Ryan Levine from Citi.

In terms of the guidance for the regulated business, is there embedded any assumption around an outcome with the pipeline FERC upcoming settlement or any color you could share around assumptions or potential upside to your current year guidance based on upcoming regulatory outcomes?

Certainly, we put those factors in as we best see the future here. I would say one of the other items that, in addition to what items you mentioned would be we expect normal weather. I mean, that's how we look at normal degree days, normal cooling degree days and factor that out throughout the year and certainly, timely recovery, and then we risk factor that as well. All those come into play with the increased guidance that we're reflecting for the full year.

I appreciate the clarification regarding the dividend policy, especially concerning payout ratios and growth based on rates. Following up on that, is there any expected or potential impact that the upcoming spin-off might have on the dividend policy, or should we treat the reinstated dividend as a baseline for future growth regardless of the outcome of the upcoming PSG transaction?

So part of our purpose again is to signal that, going back to May, we expect our future dividend to align with our peers as a regulated pure play business. At some point, we will consider optimizing the value of CSG through a tax-advantaged transaction that we recently announced. In relation to your point, we are removing CSG from the dividend equation as we evaluate that aspect. Many peers in this business do not provide dividends, and as we contemplate the long-term future of the company, we are being very specific about the target payout ratios, which specifically pertain to the regulated earnings. I believe you have a valid point as we consider a baseline for growth moving forward.

And then in terms of the potential transactions that are being considered. Is spinning what's getting the most attention, you're looking at reverse Morris Trust type transactions or any other color around options that may be on the table as the company and Board evaluate potential alternatives?

So the short answer would be those would be options and there may be more in addition to those in a tax-advantaged means. I would share that we did a market check point for this business and just felt where the market was at. And given the relatively low tax basis of this business, we just felt that we could better optimize value of the business by a more tax-advantaged separation. And so I think that should give you some color as to what our thinking here is. And then more as a reminder to you and others, we just went through a full-blown spin with Knife River that, in my humble opinion, I think created a tremendous amount of shareholder value. Certainly, we've got some new institutional knowledge that we did not have a year ago specific to a spin. I don't want to overemphasize the spin here. But clearly, we've got some experience there that we can draw on if it's the spin or some other means to find a tax advantage way to separate the high performing business that it is today.

And then last question for me. In terms of upcoming regulatory events outside of the pipeline FERC decision, can you update us on where the team is focusing their efforts across all your service territories?

So we're right now working through and had filed an all-party settlement in Montana on our electric case there, so that was filed in June, and we're waiting for an outcome from the commission on that one. And then as we look to the remainder of the year, which I think is more of your question, we are intending to file in South Dakota on the electric and gas side in August and then file a North Dakota Gas case later this year. And then as we look ahead to next year, our intention would be to file a multi-year rate case in Washington early next year.

We'll hear next from the line of Brian Russo from Sidoti.

Should we use the updated energy delivery 2023 guidance as the base year to grow EPS, as you mentioned earlier or your target to be 5% to 7%, which would be consistent with the rate-based growth?

I'll ask Jason Vollmer to touch on that one.

As we evaluate the dividend, we increased our regulated energy delivery earnings guidance from $140 million to a new range of $150 million to $160 million, a $10 million boost. We're pleased with this update. Our forward-looking guidance indicates a targeted payout ratio of 60% to 70%. When calculating the midpoint of this range, we arrive at approximately a 65% to 66% payout ratio for the current year. Echoing David's earlier sentiments, we believe this foundation offers a solid base for growth moving forward. Regarding the rate base growth you mentioned, we're actually in the 6% to 7% range, slightly exceeding that. Looking back at our current utility guidance compared to a year ago, we see an increase of 11% to 12% year-over-year. We're optimistic about the direction this is heading and believe it positions us well for future growth off the base we're establishing today.

By 2024, you are expected to have filed and concluded rate cases in almost all of your jurisdictions. Will there be a time when you are earning your allowed return on equity, or will there always be some regulatory lag due to test years and other factors? Is there an inherent lag in the utility business itself?

Brian, I'll ask Nicole again, maybe with some details. But kind of on a macro level, if we think about overall CapEx at her business along with WBI, we're forecasting $2.5 billion over the next five years, which is in excess of depreciation. And so kind of by its very nature, there is going to be some regulatory lag there, if you think of it that way. But anything to add, Nicole, I know we're tightening up that lag, but at the same time, because we're a growing rate base at that 6% to 7% that Jason noted and we've touched on earlier, there will be some inherent lag in there, some jurisdictions longer than others based on forward-looking or rear-looking test periods. Anything to add, Nicole? I didn't want to take the whole question, but I kind of did.

No, I think you summarized it so well, Dave. So just what he said, I mean, the punchline is at the rate of growth that we are achieving and expecting to get, we are going to have some inherent lag. So we've got the general rate case process that we do in all of our states and we'll continue to monitor our returns and file as appropriate. The other thing that I would add to Dave's comments, though, would be in certain of our states, we have the ability to use tracker mechanisms. So as an example, in the state of Washington, we have a pipeline tracker. In the state of Minnesota, we have a pipeline tracker. In the state of North Dakota, we have various tracker mechanisms on the electric side where we can do annual filings to reduce our regulatory lag on certain of our investment opportunities. So we're going to do those where we can. And then manage our filings according to growth in the other states where we're falling underneath are allowed. So I guess the punchline is with the growth rate we have we will continue to have to be in the regulatory arena.

And then just on CSG. Just based on your operating statistics, it looks like nearly all of the revenue growth is coming from the electrical and mechanical side of the business where transmission and distribution was flat in this June quarter versus a year ago and even when you look at the year-to-date of '23 versus 2022. Can you just kind of discuss what's going on there? I see the backlog is up on T&D but it's down on E&M. So I'm curious what kind of dynamics you're seeing in those two, what are, I would say, distinctly different end markets?

Jeff, can you add some color on that as we think about that on a year-over-year basis?

Yes, absolutely. Our T&D sector, most of the work is through our MSAs. As I mentioned earlier, we've got updates with our MSAs. We're going to see that reflection of earnings going forward as we caught up with the updated labor, material, fuel, and equipment. But then on our projects in the T&D space that contribute to our backlog are most notably the projects that I identified before, the Kansas City Streetcar extension and US 69, but also our wildfire mitigation that we're involved in in addition to the undergrounding for electrical services, a lot of joint trenching with gas and communications. And we're doing this work, of course, for our customers in Southern California and other California regions, Pacific Northwest, Rocky Mountain Midwest. But mostly, we're seeing that emphasis in Northern California from our utility customer that we have tremendous experience with and a relationship with. So some of it is timing and some of it is the CapEx and the bids that are released, which is beyond our control but we're incredibly well positioned to be able to capture this work on the T&D side. And on the E&M side, we're seeing some of these projects complete in Las Vegas but we're also involved in other projects that are on our radar that are significant in that market. And of course, we've expanded into Arizona because a customer asked us to be there and we're seeing significant contribution within that region for us. And there's another project that we're looking at in that area that we hope to report in future calls here that are going to be a contributory factor. So the work still out there is still available and we're well positioned with our resources to be able to get the best of it and continue our success.

At this time, there are no further questions in the queue. I would like to turn the conference back over to management for any additional or closing comments.

Thank you, Lynette. And thank you all for taking time to join us here on our second quarter earnings call. As you heard earlier, we are optimistic about our growth opportunities and our future regulated energy delivery projects and encouraged by the strong demand and performance of our construction service businesses as well. We certainly look forward to connecting again as we progress through 2023. And above all, we thank you again and we appreciate your continued interest and support of MDU Resources. And with that, I'll turn it back to you, Lynette.

Thank you. This concludes today's MDU Resources Group conference call. We thank you all for your participation. You may now disconnect.
