Before I move to our results on a regional basis, I wanted to share a brief update about our recently announced combination with MRC Global. Since the announcement, we have spoken with many employees, suppliers, customers, and shareholders who have expressed excitement for what this opportunity means. We discussed our confidence in becoming even better able to serve a broader mix of customers in the construction and maintenance of essential energy process, production, transmission infrastructure, downstream processing, and gas utilities activities. This combination will allow for enhanced opportunities in alternative energy, artificial intelligence infrastructure, electrification, LNG, mining, and other industrial markets.

These are areas with significant runways and bring additional opportunities to drive value creation. At the same time, integration planning is underway with joint MRC Global, DNOW teams meeting with the initial work to set us on the path for what the combined company will ultimately become. As the team embarks on this collective effort, they will focus on several areas that will be critical once the transaction is completed, including bringing together our organizations and retaining key talent, offering products and services to one another’s customers, and working to realize the $70 million of annual cost synergies the company is expected to generate within three years following closing.

As a reminder, these cost synergies are expected to be derived from public company costs, corporate and IT systems, and operational and supply chain efficiencies. The bedrock to the success of DNOW and MRC Global joining together is our expected substantial cash flow generation capabilities and robust balance sheet, providing a strong foundation for continued investment in organic and inorganic growth and driving shareholder value.

Our supplier relationships have always been incredibly important to our success. Through this transaction, we expect to build upon those valued partnerships to serve our customers more holistically and grow the combined business. This opportunity to bring our two organizations together is thanks to the tremendous efforts of my DNOW colleagues and the MRC Global team.

As the customary regulatory and shareholder approval processes proceed, I want to highlight that the final S-4 Definitive Proxy Statement was filed yesterday, and DNOW and MRC Global each filed a pre-merger notification and report form under the HSR Act on August 1st. We look forward to welcoming MRC Global and their valued team members in due course and bringing our organizations together to drive growth and value for our customers, partners, and shareholders alike. We cannot wait to see all we will accomplish together.

Question and Answer

Q - Adam Farley

Good morning. Maybe starting first with the merger with MRC, thinking about - thinking through the work, you know, what are the most difficult parts of the integration likely to be? How do you manage the risk? And, you know, how do you keep your employees focused during this period?

A - David Cherechinsky

Well, you know, our orientation, Adam, is around bringing the notion to our employees that this flat-out is going to make DNOW and MRC Global combined a better company. We’ve done transformational combinations in our history. And the first cardinal rule is we’re going to focus on the customer post-close like we are today. It’s all about the customer.

We’re going to align our teams early in the process. Get everyone focused on external matters, that is managing the supply chain, working very closely with our - the manufacturers we support, becoming better distributors to the manufacturers we support, focusing on our customers and being a better supplier to them with a broader array of products and solutions, with more locations closer to them, with a broader array of inventory, and simply just a company much better able to satisfy customer requirements as they evolve, especially in this consolidation experience we’re seeing with our top customers. So the focus is on how do we grow the business going forward? That’s the focus.

You know, having done this before, you really have to, the focus must be an external one. It must be focused on the supply chain and our customers and getting everyone pumped about the future. And we’ve got a high caliber team that’s focused on the integration and we can talk more about that in a bit.

[…]

Q - Jeff Robertson

Thank you. Good morning. Dave, in your comments with respect to the MRC combination, you said you’ve had some discussions with vendors and customers, and I know the $70 million of estimated cost synergies is mostly related to corporate costs. Are you seeing opportunities at this early stage that you can drive some synergies with vendors and with customers that, excuse me, ultimately add to those costs in accretion over time?

A - David Cherechinsky

Yeah. We spend a good deal of time on estimating those synergies, and I’m not going to raise the number. It’s going to take a lot of work to get there. You know, we’ve just kicked off a joint MRC Global/DNOW team with, you know, high-caliber talent from both organizations, both groups having deep understanding of their respective organizations, and the focus is on people and talent and growth. You know, tomorrow, you know, once we close the deal, we want to be focused on growing our business and being a better distributor to our customers, like I said. So my focus is on growth and the promise of what this combination can mean, really not from combining locations.

It’s certainly not, you know, considering how that will transpire as we go through this integration process. So the focus remains on growth and the promise of the combination rather than focusing on field consolidations where we’re going to realize most of the benefits from the complementary nature of each of the firms.

Q - Jeff Robertson

As you look at the combined company, Dave, are you seeing or do you expect that with less exposure to upstream than DNOW standalone has, do you see that as an increased visibility of the future earnings power of the company as you’re less tied to the drilling and completion capital cycles?

A - David Cherechinsky

Well, it certainly will make the combined company less, you know, focused on upstream in particular, but we still see that as an important part of our business. We want to grow our position in upstream, but I think that diversification is the real opportunity here. MRC has built very strong end markets where we play such a small role. We can use our complementary locations, sales teams, non-crossover customer access to grow both sides of the businesses. So I think the real opportunity there is to, you know, rely on cross-selling to grow the company.

Q - Jeff Robertson

And then lastly, do you anticipate a lot of that coming from electrification in terms of AI and just other build-out of the grid? I think that’s part of the strength of MRC was exposure to the gas utilities and products markets.

A - David Cherechinsky

Yeah, Brad, do you want to hit that a little bit?

A - Brad Wise

Yeah, good morning, Jeff. Yeah, I think Dave in his prepared remarks identified a number of growing industrial markets. Electrification, of course, is, you know, we’ve seen many of the OFS sector as well as other providers work to move away from fossil fuels on the electrification side. Of course, AI data centers is a very exciting space. I think the combination of our companies going forward would just bring more capabilities around that area. I know we highlighted a successful win selling some valves to the data center project. I think the prior quarter we highlighted, you know, winning feed gas, 5,000 fittings on a feed gas line to a power plant that’s feeding a data center. So, you know, we’re starting to see more and more opportunities in our quotations and our business development efforts, you know, really focusing on, you know, those growing end markets that we identified. Certainly, midstream had tremendous growth there, you know, approximating 27% of DNOW revenue this quarter. And then as you look down, you know, further downstream with opportunities with LNG export, we’re seeing opportunities there. We’re seeing, as I mentioned, opportunities with data center, data center construction. And then the power generation side on that too and what that means for the future of natural gas demand as, you know, some analysts are projecting, you know, natural gas operating rigs to grow potentially here second half, certainly in the 2026. So, you know, that certainly helps us on the upstream side as well. So, you know, we’re excited about the future and what the combination of these two companies could bring to many of these diversified industrial markets.

Q - Jeff Robertson

Thank you, Brad.

[…]

Q - Blake McLean

Hey, I appreciate all the color this morning and I appreciate really that last series of questions and answers around kind of the total end market portfolio and the opportunities and threats there. Maybe just like expanding on that a little bit, how do you think about how the mix of NewCo sort of evolves over the next one, two, three years as it relates to those sort of total end market, you know, that portfolio of total end markets?

[…]

A - Brad Wise 

Well, thank you for the question. Yeah, I think, you know, in our previous merger call announcement, we talked about what combined co-end market would look like, you know, from an upstream, you know, roughly about $5.3 billion in revenue, about 41% for that upstream, about 21% of that midstream, about 17% gas utilities - or 21% gas utilities, and, you know, in the balanced downstream industrial. So, you know, we’re excited about certainly, you know, increased diversification there.

I think it offsets some of the cyclicality in the upstream market, you know, certainly that we’re accustomed to over the many years here at DNOW. You know, I would say, you know, moving forward, you know, many of those industrial markets are projected to grow with various degrees of CAGR. You know, certainly the gas utilities sector, I believe, is increasingly, you know, going through modernization and replacement as population grows and demand increases there.

You know, AI, you know, the demand for, you know, more gigawatts tied to AI development and data center construction, you know, that’s an exciting area, I think, for, you know, NewCo, you know, really with the exposure that both companies have, you know, traditionally had and are gaining, because it’s a new growth area, both on the power gen side, on the general contractor side with the construction, with the operators and some of these, you know, hyperscalers like, you know, Meta, Microsoft, and others, you know, we’re starting to see, you know, more activity and build relationships there. And then also, you know, continue to build out a midstream infrastructure to really satisfy that, you know, call it, you know, five nines of reliability for, you know, power demand for those data centers.

And then, you know, really exciting is LNG, you know, we commented on a couple of wins there. You know, we’ve seen, you know, our, quote, backlog tied to LNG continually increase here quarter-over-quarter. You know, we hope to get some of those across the finish line over the next, you know, four to six quarters here. They are long cycle projects as, you know, U.S. and Western Canadian companies, you know, look to expand their export liquefaction terminals and to be able to capture demand from Europe and Asia to help feed those markets on a global LNG basis. So those are some of the exciting opportunities we have, you know, looking forward. And I think NewCo, and its combination with our combined sales force, our success, our success with customers and our supplier relationships, you know, can present an exciting opportunity going forward in the market.

Q - Blake McLean

Okay. Appreciate that, color. I mean, we would agree that the growth profile in a lot of those places just feels different, right? One more just kind of maybe quick follow-up. Could you talk a little bit about impact from tariffs in the back half of the year and how you guys are sort of thinking about that and navigating those challenges in this environment?

A - David Cherechinsky

[…]

So we’re growing our business organically. We’re making smart acquisitions. We’re integrating those businesses smartly. And we want to grow all the end markets in the standalone DNOW and in NewCo. We want to grow our business and we’ve been very successful at doing so. We talked about the second quarter having the highest EBITDA second quarter in our history. That’s something to say after three years of market decline.

So we’re excited about where we are. We’re excited about how, you know, the strengths of the product offerings are so complementary in this merger. We’ll have more locations with access to more customers with a better rate of product services customers. So we start off strong. We have two lean organizations who are focused on the customer. Our cultures are similar and we see coming together as a real opportunity. Both organizations see that. So we’re very excited about where we’re at, how we’ve been able to weather slower times and produce record earnings and reliably generate free cash flow.

I just want to mention one statistic. At the end of 2023, we had $299 million in cash. 18 months later, we have $232 million in cash. In that timeframe, we spent $357 million on M&A and share repurchases. So we’re an active, growing organization. And we’re going to be even more so as we combine together with MRC Global. So we’re excited about where we’re at. We want to grow all our end markets. We generate cash and can grow inorganically and organically. And we’re excited about that.
