Thank you, Nathan. Welcome, everyone, and thank you for joining us today. I am excited to present our first earnings call as a public company and even more excited to discuss our strong results and the solid momentum we are seeing. Knight River achieved record second quarter revenue, record net income and record EBITDA while also compiling a quarterly record backlog. We saw improved results from last year in each region as our operations benefited from price increases and targeted bidding strategies across all consolidated product lines. This is a direct result of our competitive EDGE strategy for sustainable and profitable growth, which I will discuss further in a minute. For the quarter, we reported revenue of $785.2 million, a 10% increase from the same period in 2022. Our second quarter EBITDA was $125.1 million, which is a 43% increase year-over-year. Our adjusted EBITDA was $126.3 million, a 40% increase year-over-year.
Nathan will discuss EBITDA and adjusted EBITDA in more detail so you can fully appreciate the significant underlying momentum in our business and the progress we are making with the execution of our EDGE plan. Based on our strong first half and the tailwinds we see in our operations going forward, we are raising our guidance for revenue and EBITDA. In addition, we are initiating guidance for the adjusted EBITDA of $330 million to $380 million for 2023, implying year-over-year growth of 20% at the midpoint and underscoring the demand we are seeing.
Nathan will discuss this further. These are very strong results, and they are a testament to the strength of our 6,000 team members and of their support of our EDGE strategy. Our results also show the strength and resiliency of our aggregates-led vertically integrated business model. While new to the public markets as an independent company, our business and operations are well established with a track record of executing on our goals and successfully expanding our business in midsized high-growth markets. Our mix of construction materials and contracting services provides resiliency and contributes to our industry-leading return on invested capital.
We are a top 10 aggregate producer in the United States with 1.1 billion tons of proven reserves. Our major downstream products include ready-mix concrete and asphalt, and we also performed contracting services across 12 of our 14 states in which we operate. Tying it all together is our life at night, which is the name we give to our strong people-first culture. We are committed to taking care of our team and being an employer of choice as we work together to build our communities. I've been with Knife River for 30 years, and it was a thrill for me to join our leadership team on the balcony of the New York Stock Exchange on June 1 to ring the opening bell and watch as shares of KNF stock were traded for the first time. Our separation from MDU Resources into a stand-alone public company has allowed us the opportunity to unlock our full potential and expand upon our strong platform.
The decision to spin-off enables us to more effectively allocate capital resources and pursue strategic efforts aimed at growing our business and creating long-term value for our shareholders. Key among the strategic efforts is our competitive EDGE plant. EDGE is Knife River's framework for sustainable and profitable growth. The letters in EDGE stand for EBITDA margin improvement, discipline, growth and excellence. Our team is laser-focused on these initiatives and objectively, we have delivered.
First, we improved our trailing 12-month adjusted EBITDA margin to 13.5%, a significant increase from our 2022 year-end adjusted EBITDA margin of 12.4%. Much of this improvement was the result of our discipline in aligning the value we deliver to our customers through price optimization. For the quarter, we saw double-digit price increases on all our materials, including aggregates, ready-mix, asphalt, cement and liquid asphalt. In addition to strong materials pricing, we improved our construction margins for the quarter by 280 basis points through the disciplined bidding strategies and project execution.
Our pricing initiatives, coupled with the efficiency enhancements being implemented by our process improvement teams and the strong underlying demand we are seeing in our regions has us on track to hit our goal of 15% adjusted EBITDA margins by 2025. Second, we have been highly disciplined at allocating capital and managing cash, evidenced in the quarter by paying down $35 million in debt to improve our financial flexibility. Third, we continue to prioritize organic and acquisition-related growth. Our business development team has been busy analyzing a number of strategic opportunities to grow our aggregates position, a key objective for us, both by greenfield and new sites along with several prospective acquisitions.
Looking to the future. We remain optimistic that local, state and federal funding will continue to support strong construction activity. This funding has contributed to our record backlog of $1.04 billion. Finally, we are focused on excellence in everything we do, starting with maintaining our people first culture. These efforts are measurable in a number of ways, including our commitment to safety, our retention rates and our outreach efforts. A stat I'm proud to report is our outreach efforts this year to over 1,200 historically underrepresented organizations in our communities. Our world-class Knife River training center has been at the heart of this outreach effort and will continue to provide best-in-class training for our existing team members and future construction workers.
Ultimately, our efforts to be the best-in-class drive our continuous pursuit of excellence. We believe that our near- and long-term opportunities to continue to build on the momentum we have seen in each of these EDGE initiatives. At our Investor Day in May, we outlined our goals and a well-defined path to achieving strong and balanced revenue growth, adjusted EBITDA margin expansion to 15% by 2025 and 20% in the long term, generating attractive free cash flows, maintaining a healthy balance sheet and sustaining our industry-leading return on invested capital.
We are just getting started, and I'm proud to be able to report on some of our initial successes. I'll quickly recap the quarterly results for our reportable segments before turning the call over to Nathan for additional details on our financial performance. Starting in the Pacific region EDGE-related pricing initiatives across all product lines contributed to increased revenue, gross profit and EBITDA. We saw higher demand in Hawaii as the local economy continues to regain momentum through tourism and military spending.
We also experienced higher material demand in Northern California. In addition to improved margins for our contracting services in Northern California, we also saw ready-mixed volumes increase based in part on our late 2022 acquisition in Modesto. Partially offsetting the region's increased revenues were lower asphalt volumes and decreased contracting services revenues, both resulting from the late start to the construction season.
Moving to the Northwest region. We enjoyed exceptional results in the quarter, driven again by our pricing initiatives across all product lines and also by strong demand in contracting services. Revenues in the Northwest improved 19% year-over-year and EBITDA improved 75%. Higher asphalt and ready-mix volumes more than offset the decrease in aggregate volumes associated with project timing as the region is benefiting from more available work than in previous years, including public agency work, data centers and parking structures.
We are in the process of commissioning our new state-of-the-art prepress manufacturing facility in Spokane, Washington. We acquired the Spokane operation in 2020, 1 of 8 acquisitions we have made in the Northwest since 2018. Next is our Mountain region, which had a strong quarter and was ahead of our record year in 2022. We saw revenue growth of 3% and EBITDA growth of 14%, with price increases across all product lines positively impacting segment revenue.
Our contracting service business is larger as a percent of revenue in this region than any other, and it continues to perform well. We have a record second quarter backlog of $377.3 million, an 8% increase from last year. I mentioned earlier, as part of our EDGE strategy, the process improvement teams are what we call the PIT Crews. This is a cross-section of internal product line experts and outside consultants to help each region identify opportunities to lower production costs and improve operating efficiencies. The PIT Crews spent approximately 1 week per month, completing their work at individual business units. The Mountain region has the benefit of having a PIT Crews in the region twice now, and they have identified and implemented meaningful improvements at 2 of their larger aggregate operations. In the North Central region, revenue improved 12% and EBITDA increased 52%. Most notably for the quarter, EBITDA margins improved by 340 basis points as the region embraced EDGE-related bidding strategies.
On the material side, aggregate price increases across the region related to the implementation of EDGE initiatives more than offset lower volumes. Finally, our all other segment includes our Energy Services region, South region and Corporate Services. For the second quarter, revenue improved $5.8 million year-over-year as a result of higher average selling prices for asphalt products and ready-mix concrete, partially offset by the December 2022 divestiture of nonstrategic assets in Southeast Texas. EBITDA improved $1.2 million year-over-year to $5.4 million as a result of increased pricing. Corporate costs increased related to our recent spin, and we are diligently analyzing our SG&A. Once we have fully onboarded our dissynergies from a timing perspective, we expect to be able to drive greater productivity. As I went through some of the highlights of our segments, there are common themes across our business. First, our choice of midsized, high-growth markets and our leadership in those markets position us well to benefit from the demographic shift we are seeing to markets where Knife River is strongly positioned.
Second, our laser focus and continuing to implement our EDGE strategy is already delivering exceptional results, and we believe it will keep us well positioned for profitable growth and long-term value creation. Third, our people-first culture and the commitment of all our team members to our core values and business objectives makes me extremely optimistic about the future for Knife River and the value we can deliver to our shareholders.
I will now turn the call over to Nathan for a detailed look at our financial results. Nathan?
