Thank you very much, Diego, and good morning. And welcome to our fiscal year 2026 first quarter's earnings conference call. I'm glad to report this morning that we had a very strong first quarter beginning to our 2026 fiscal year. Now during this past year, we had many different points to navigate. And as last quarter, we now had a new one: the longest US government shutdown in history. But during all of these challenges, so during this last year and during the first quarter of this year, we've remained very focused on the enduring markets of water supply, water treatment, flood control, and environmental stewardship. All of which remain in very high demand. And, yes, water is not going out of style. Now as you're gonna hear this morning, even with the government shutdown, we grew our revenue 8%. We expanded our margins by 140 basis points on a GAAP basis. Deep Vertical will talk more about this in a bit. And we improved the quality of our backlog by winning more front-end work and increasing the embedded margins that we have in the new projects that we've been awarded just this last quarter. Now today, Steve Burdick, our Chief Financial Officer, will provide additional details on our financial performance on a full GAAP basis. Roger Argus, Tetra Tech, Inc.'s President and CEO designate, will provide an update on our growth markets and market outlook. And with that, I'd now like to share with you an update on our financial performance and business. As we both performed in the first quarter and as we see ourselves moving forward into the rest of 2026. I'll start with again, we began 2026 with a strong first quarter, as I just indicated. We had a net revenue of $987 million in the quarter, which is up 8% from the prior year. In the quarter, we generated $131 million in operating income, which is up 12% from the prior year. And finally, our earnings per share was up even more, up 17% in the first quarter of last year, resulting in an adjusted earnings per share of 34¢ for the quarter. And that's an adjustment down from our GAAP number. Our actual GAAP earnings per share was $0.40 in the quarter, and Steve Burdick will go through a bit more of that in the Chief Financial Officer's presentation in just a few moments. I would like to present our performance by our segment. We do have two segments, the government services segment and a commercial and international group segment. The government services group segment delivered a strong quarter with margins of 18%, up 40 basis points from last year. In the first quarter, our government services group net revenue was $382 million, which grew 5% from last year. And that was during a quarter where the US government was shut down for about six weeks of that period or about half of the entire quarter. Our commercial and international group segment also delivered a strong first quarter. The Commercial International group's revenue was up 10% to $605 million driven by growth in The United Kingdom and in Ireland with strong water programs in both geographies and with new digital automation programs in Australia. Our Commercial and International Group's margin for the first quarter was 13%, which was also up similar to GSG, up 40 basis points from the prior year. Our commercial International Group's benefited from strong performance in The United Kingdom, in Canada, and an improving business in our Australian activities. I'd now like to provide an overview of our performance by our end customers. This quarter, our federal work was up about 7% from the prior year. Primarily for work with the US Army Corps of Engineers, designing flood protection structures, upgrades to locks and dams, and design of new inland waterway navigation systems. Overall, our US federal work was about 18% of our overall business in the first quarter. In The United States, our state and local markets continue to be very strong. With a 10% growth rate driven by municipal water treatment and digital water modernization, especially in the water stress regions of Texas, Florida, California, and Colorado, which Roger Argus will speak more to here in just a few moments. Our US commercial work was actually down slightly but this is pretty much as we expected. It was driven by reductions in renewable energy work this 2026 compared to a very strong renewable energy practice that we had a year ago. This reduction in our renewable energy work was partially offset by growth in high voltage transmission and permitting and engineering work that we're doing here in The US. Our international work was 48% of our overall business or our overall revenues or net revenues, and it grew at a 13% rate during the quarter. International growth included strong increases in The United Kingdom, in Ireland, as I've mentioned earlier, primarily around the water businesses. We also saw growth in our Canadian infrastructure programs, which we see strengthening really all across Canada. And has been one of the strong lights for us. And, actually, in improving business in our Australia activities, where we've actually saw the reductions of bait during the first quarter. Now like to discuss our backlog, which held steady during a strong revenue quarter that included I've mentioned a few times, a US federal government shutdown. Overall, we see the quality of our backlog much higher than before as measured by the proportion of front-end work that we have embedded in our backlog which also brings higher embedded margins. You can imagine, we did see a slowdown in our US federal client orders in the first quarter due to the government shutdown that began on October 1 and continued for the first six weeks of the fiscal year. And even with the federal government reopening on November 12, the start-up for the government was still pretty slow because it started up in November right before Thanksgiving. And continued through the holiday season. So we never saw it fully return to a level that we would have either expected or hoped for. While new project orders from the US government were slow in the first quarter, new contract awards task orders, and project start-ups were very strong, our US state and local clients. Commercial clients, international clients, collectively resulting in an overall stable pretty flat backlog from what we saw from the first quarter of last year. As we look forward, we expect that with more clarity on US federal budgets and appropriations, the pace of US federal orders will increase beginning late in the second quarter and continuing through the second half of our fiscal year. Now I'd like to turn the presentation over to Steve Burdick, our Chief Financial Officer, to present more details on our financials for the first quarter.
