Good morning, and welcome to Northwest Pipe Company's first quarter 2023 earnings conference call. My name is Scott Montross, and I am the President and CEO of the company. I'm joined today by Aaron Wilkins, our Chief Financial Officer. By now, all of you should have access to our earnings press release, which was issued yesterday, May 3, 2023, at approximately 4:00 P.M. Eastern Time. This call is being webcast and it is available for replay. As I begin, I'd like to remind everyone that statements made on this call regarding our expectations for the future are forward-looking statements, and actual results could differ materially. Please refer to our most recent Form 10-K for the year ended December 31, 2022 and in our other SEC filings for a discussion of such risk factors that could cause actual results to differ materially from our expectations. We undertake no obligation to update any forward-looking statements. Thank you all for joining us today. I'll begin with a review of our first quarter performance and outlook. Aaron will then walk you through our financials in greater detail. Our first quarter results came in slightly better than our expectations. We generated revenue of $99.1 million, a decline of 9.4% compared to the prior year quarter. Revenue from our steel pressure pipe segment totaled $63.5 million, reflecting a decrease of 14.9% over the prior year quarter, mainly due to anticipated customer-driven delays, which affected the production timing of our projects in backlog, in addition to severe weather events, which led to unscheduled downtime at multiple of our facilities in the first quarter. This resulted in relatively flat production volume year-over-year. That said, we ended the quarter with a strong backlog, including confirmed orders near record territory at $370 million, which was down marginally from our all-time highest $372 million at year-end and up from $341 million as of March 31, 2022. We entered 2023 with a very strong backlog from robust bidding in the second half of the year, which should carry us through to deliver strong steel pressure pipe results in 2023. We do expect bidding volume to be down moderately in 2023. As a result, backlog in the second quarter may moderate lower, but is anticipated to still remain high by historical standards. On the pricing side, hot-rolled band steel prices have increased fairly rapidly since the start of this year, which in general bodes well for our steel pressure pipe business. Now, turning to our precast segment. Precast revenue increased 2.7% from the prior year quarter to $35.6 million, driven primarily by higher selling prices, given continued strong demand for our precast products, as well as increased raw material input costs. Our sales were partially offset by lost production days, resulting from the ongoing ERP implementation project at ParkUSA as anticipated. As well as severe weather events we experienced in the first quarter. Our precash related order book remains strong in totaled $58 million as of March 31 2023, despite moderating down from $64 million as of December 31, 2022, and from $66 million as of March 31, 2020. While our order book was impacted by a softer US residential housing market, we continue to believe, we are well positioned to benefit longer term, given our strong presence in Utah and Texas, as these particular states are within the top five fastest-growing markets in the US. Further, the ParkUSA products provide unique advantages for growth in the commercial construction market, despite near-term macroeconomic concerns, highlighting a key benefit of our diversification strategy. Our first quarter consolidated gross profit increased 12.1% year-over-year to $16.6 million, resulting in a gross margin of 16.7%, up from 13.5% in the first quarter of 2022. Our steel pressure pipe gross margin of 12.2% improved by approximately 260 basis points over first quarter 2022, primarily due to the higher margin quality of projects that we have in backlog, as well as improved project pricing. Partially offsetting the strength in our steel pressure pipe gross margin in the first quarter was a negative impact from severe weather events and customer-driven production delays that affected our overhead absorption levels. Our precast gross margins improved by approximately 280 basis points over the first quarter of 2022 to 24.7% of precast sales. The improvement was predominantly due to improved pricing, despite some of the ongoing challenges that we continue to face with the ERP implementation, severe weather events that cause unscheduled downtime and the impact of rising interest rates on the residential housing market. Next I would like to provide an update on our growth initiatives. To position Northwest Pipe for increased resilience through market cycles, our first strategic priority is to continue driving growth in the Precast related space, which we believe has attractive through-cycle characteristics. The integration work, post our acquisition of ParkUSA remains ongoing as we continue to assimilate the company into our operations and culture. And we are making solid progress toward finalizing the Park ERP implementation project. As we discussed on our last call, we've encountered challenges, which including controlled deficiencies related to ERP system implementation have required us to take planned downtime at our plants, as we work toward achieving optimum system functionality. This downtime reduced both our production levels and shipments adversely affecting both our Precast revenue and gross margins during the first quarter. We expect we will experience additional downtime in the second and third quarters of 2023, before returning to a more normalized operation towards the end of this year. To reiterate, we view this project as a short-term challenge and is necessary to achieving our strategic growth objectives. Next, I would like to turn to our ongoing organic growth strategy for Precast, which we refer to as product spread. As a reminder, Level 1 product spread is focused on building out capacity utilization at our Texas-based Park plants to maximize overall production capabilities. The Park sales group has made good progress on growing our sales outside of the state of Texas from the Park facilities with approximately $2 million of orders booked outside the state of Texas in the first quarter and over $8 million in the last 12 months. Our objective remains to continue growing the Level 1 product spread throughout 2023. The premise for Level 2 product spread is to produce and ship Park products out of our other Northwest Pipe plants. We are utilizing our pre-existing Geneva Precast operations as the pilot location for Level 2 product spread activity. We are successfully continuing to bid new projects that are currently being produced and will be produced out of our Geneva plants. So far in 2023, we are in production on four Park product orders at Geneva with more scheduled to come. Once Park products are comfortably established at Geneva locations, we will expand upon this strategy to produce these products at additional Northwest Pipe legacy locations. We remain bullish on the long-term growth prospects for the Park business. Additionally, part of our organic growth initiatives include reinvesting in our Precast locations, particularly in the Geneva operations in order to increase our production capabilities and capacity through expansion and automation. For example, we are continuing work on a $16 million new RCP manhole facility at our Salt Lake City Utah plant, which is anticipated to become operational in the fourth quarter of this year. While driving growth in the Precast related space remains our top strategic priority, we are also focused on maximizing our steel pressure pipe water transmission business to become as efficient as possible. We currently have about 55% market share in this space with fairly limited acquisition growth opportunities in a market that has been dramatically consolidated over the years. With our nationwide footprint and as an industry leader in this space we are well positioned to participate in the ever-growing amount of Water Transmission grid infrastructure projects required to support the increasing US population. And we continue to be fixated on enhancing shareholder value over time. As such, we are focused on opportunities for further cost reduction measures, lean manufacturing and maximizing margin over volume. Next, I'd like to discuss projects on some current and upcoming Water Transmission projects that are bidding in the steel pressure pipe market. In the Eastern markets, the ongoing multi-year multi-agency Houston Surface Water Program is bidding 3,600 tons of pipe this year across multiple projects with additional sections planned for 2024 for West and North Harris County Regional Water Authorities. The Alliance Regional Water Authority program in Central Texas is another multi-agency regional water program. The program includes a large pipeline, pump stations and treatment facilities. The final remaining 2,700 tons of pipe is expected to bid this year. In North Dakota, progress continues on the 140-mile 87,000-ton Red River Valley Water Supply Project. The first two segments were awarded to Northwest Pipe and installation is currently underway. We are closely tracking the outcome of further budget approval for future segment construction. In the Western market, California's Prop one $7.5 billion bond for water infrastructure has created the much-needed funding for projects within the state. The following Prop 1 projects are expected to start construction in the next five years. The site's reservoir is a water storage project that has received funding from Prop 1. It will involve over 30 miles of 144-inch pipeline. Additionally, site's reservoir received $30 million in IIJA funding this past quarter. Harvest Water is a program intended to provide recycled wastewater for agricultural use in the Sacramento area. This program includes nearly 25 miles of 30-inch to 66-inch pipeline. The first segments of this program are expected to bid in late 2023. Los Vaqueros Reservoir Expansion program provides a substantial capacity improvement to the existing reservoir and conveyance facilities in Northern California. The program, includes approximately 22 miles of 48- to 96-inch pipe. Willow Springs Water Bank will create 500,000 acre feet of underground water storage in the Antelope Valley. The project includes approximately 16 miles of 30- to 84-inch pipe. Water reuse programs have generated new opportunities in California market on which we expect to see bidding activity continue for the foreseeable future. MWD is heading a regional water reuse pilot project in conjunction with L.A. Sanitation District. This reuse program would treat and recycle water from one of the largest reclamation facilities in Southern California and involves 60-plus miles of large diameter pipe. The current demonstration facility has been in operation for two years. Preliminary design and permitting is ongoing in construction of the full-scale treatment and conveyance facilities could begin as early as 2025. MWD secured a $224 million refill loan in October of 2021 which will fund nearly 50% of the anticipated construction cost. SNWA a Las Vegas water wholesaler in Colorado River water user has also played significant financial support for this program. The MWD PCCP rehabilitation programs will result in about 5,000 tons annually over the next 10 to 15 years. This program includes approximately 81 miles of pipe from 75 to 120 inches. Southern Nevada Water Authority has begun moving forward in earnest with the expansion of the southern part of their water delivery system. This program which has recently started preliminary design activity will include approximately 25 miles of 78-inch steel pipe with construction tentatively scheduled for 2025. In Utah design and permitting continues on 150-mile 69-inch Lake Powell pipeline. This pipeline will provide an alternative source of water for Southern Utah. Construction is proceeding on in earnest in New Mexico on the US Bureau of Reclamation Navajo-Gallup Supply program. The final major phase of this pipeline construction for this program is advertised to bid in early 2024 and includes 2,800 tons of steel pipe. New Mexico Governor Grisham recently announced $160 million in IIJA funding for the completion of the Eastern New Mexico Rural Water System. Remaining pipeline segments include 15,000 tons of steel pipe to convey water from the Ute Reservoir in Northern New Mexico south to water users in the Greater Clovis area. Before I conclude, I'd like to summarize our outlook. Our outlook for 2023 remains positive. Aside from the challenging first quarter that had many of the same issues we experienced in the comparable period last year, we carried a robust near record territory backlog into 2023, which we believe will set the pace for a strong year despite anticipated moderation in the amount of tons bidding in 2023. In regard to the second quarter, our steel pressure pipe business we anticipate similar production levels as to what we saw in the second quarter of last year given the same strength that we've been maintaining in our backlog, which should fuel improved gross profit and margins. In our precast business, we remain cautiously optimistic demand will remain fairly strong for the near term despite current macroeconomic uncertainty surrounding the residential housing market and current rate environment. That said, we expect we'll be able to maintain strong business levels and margins in the second quarter even with a slight moderation in our order book resulting from macroeconomic factors. The precast business is expected to have a solid 2023 of only modestly from what many of you consider to be an all-time record year in 2022. In summary, we are pleased with our solid start to the year which surpassed our expectations. We remain bullish on our growth initiatives to increase our free cash related business to a similar size, as our steel pressure pipe business. Continued by strong demand for our high-quality precast products and growing infrastructure needs in the United States. Looking ahead, we will remain focused on finalizing the integration of ParkUSA as quickly and efficiently as possible. Number two, persistently focus on margin over volume; number three, continuing to implement cost reductions and efficiencies at all levels of the company; and number four, continuing to identify strategic opportunities to grow the company and once we've completed the integration work with ParkUSA. Thank you our dedicated team at Northwest Pipe for your commitment to the excellence stand and for operational safety. I will now turn the call over to Aaron, who will walk through our financial results in greater detail.
