Thank you very much, Paul, and good morning, and welcome to our first quarter fiscal year 2025 earnings conference call. It's been a very eventful month of January so far. Just over three weeks ago, the Eaton fire struck right here in Pasadena within about a mile of our corporate headquarters, and an equally destructive fire occurred a little over 20 miles away from our headquarters, in the Palisades here in Los Angeles County. Unfortunately, some of the Tetra Tech staff did lose their homes, and many, many that work here in our Pasadena headquarters, were evacuated. And in fact, some still remain evacuated all the way up until today. But most importantly, all of the Tetra Tech staff, are safe. And we certainly, do send our condolences to those that were unfortunate, because there were fatalities, in both of the fires. So, it was not a great start to the month just from a personal impact, to Tetra Tech staff and individuals throughout Los Angeles County. Just ten days ago, January brought us, the inauguration of president Trump and, the incoming of his new administration and they are rapidly aligning the government to their policies, their programs, adjusting contracts, to areas that are in line with their mandate, as they're bringing it, and much of it's been implemented through executive orders and other actions. In fact, just beginning this week, just a few days ago, our USAID or foreign development contracts, for the most part, have all been put on hold for up to 90 days, while the administration, embarks upon a review of all of these existing contracts. Now while these may seem like a lot of change in the industry, it's not that dissimilar from what we've seen in temporary government shutdowns. We have seen programs that have been put on hold. Typically, it becomes quite quickly when a budget hasn't been arrived at, through Congress, and so we have seen this in a different form, maybe it wasn't executive actions, but we have seen the net effect be quite similar here, in the marketplace and here at Tetra Tech. But no doubt, Tetra Tech's strength has always been in our ability to respond and to adapt to change, whether it's mobilizing our staff to respond to fires or other disasters or hurricanes or aligning our staff with our clients' priorities. We can move quite quickly. Our staff are in extremely high demand, and the ability to put them on other programs during these periods is actually quite high. Our services across the board continue to be in very high demand for things such as providing clean, secure water supplies, ensuring a healthy environment, or designing and putting in place resilient infrastructure such that, it will be not impacted in the future regarding disasters or any other items. Now presenting with me today, I have Steve Burdick, our Chief Financial Officer, who'll be providing additional details on our financial performance and capital allocation for the company. I also have doctor Dr. Leslie Shoemaker, who will provide remarks on some of our key growth markets. But before I get to, or before we get to our drivers and outlook for fiscal year 2025, I'd like to first share with you the results of our first quarter. We had a very strong first quarter and beginning of fiscal year 2025. For the quarter, we achieved new record results, and not just record results for what we would normally perform in the first quarter, but high points for any quarter in the entire history of the company. In fact, our net revenue, which increased to $1.2 billion in the quarter, and again that's for net revenue, it was up 18% from the prior year to an all-time record for any quarter in the company's history. Our operating income was $138 million for the quarter, an increase of 24% from the prior year. And by the way, I'll make a note, a year ago, that was a record high. So, by having income being up 24% from a record first quarter was really quite impressive here for the company, and of course, that's an all-time high for first quarter for the company. This strong performance resulted in earnings per share increase of 25% over the previous year to $0.35 for the quarter, which was above our own guidance range and, of course, above consensus that were provided in the marketplace. And through all of this and with this very large revenue being recognized in the quarter, it was even more impressive that our backlog grew, and it grew to $5.44 billion, up 15% from the first quarter of last year. I would like to discuss and present our performance by segment. Both of our segments contributed significantly to this outstanding performance in the first quarter. For the first quarter, the Government Services Group, or GSG segment, increased its revenue by 36% year-over-year to $601 million, and this is the first quarter we've ever had a GSG segment over $600 million. It was really quite an accomplishment. Now GSG generated a margin of 13.9% margin for the quarter. GSG's revenue growth was largely driven by significantly higher-than-anticipated work in Ukraine for our USAID client. While this is extremely important work and, it's been quite successful supporting the U.S. government in this critical mission, the contracts that we have do carry lower margins due to the cost reimbursable nature of the contracts. If you took out the Ukraine work that we did this last quarter, you would have seen GSG's margin at about 15.4%, which is extremely strong for the first quarter of the year where we have holidays, such as here in the US, Thanksgiving, Christmas, and other times off. So, to be in the, fifteens and, in fact, above 15% for this first quarter, extremely strong for the company. The Commercial International Group or CIG segment delivered a 13% margin. Quite pleased with that. It's up 50 basis points from last year, which is right in line with our forecasted annual increase in margins. The CIG segment had net revenue of $596 million, which was up 4% year-on-year. I will note, we've -- this is the closest balance we've had between government services at $601 million, CIG at $596 million. We really have about half of our work in GSG and about half of our revenues in CIG, really quite balanced for the company. I would like to provide an overview of our performance by our end customer and how we look at how we contract in the marketplace. Work for our U.S. federal clients was up 32% from the same quarter last year. Now without contributions from our Ukraine work, our federal revenues would have been up 7% year-over-year, which is exactly in line with our forecast for the federal government. This growth is driven by increases in our defense infrastructure and many of our critical civilian programs that we undertake. Our state and local revenues were up an amazing 47% year-over-year. Now this was driven primarily by extraordinary hurricane response activity that we undertook in areas of Florida, Georgia, Carolinas and other areas in the Southeast, in response to hurricanes Helene and Milton. We also saw growth though. It wasn't -- this growth wasn't just from these hurricanes. We also saw material growth on our digital water modernization and advanced water treatment projects. Now if we did take out the impact of the extraordinary hurricane response activities, our state and local revenues would have been up 19% year-on-year, very strong. Our U.S. commercial net revenues were up 7% year-on-year, again, very much in line with our forecast for the quarter, driven by growth in high performance buildings, design services, as well as our support for Fortune 500 clients. And finally, our international work, work that we actually contract for perform outside of the United States represented over a third of our revenues in the quarter. Our international work includes the United Kingdom and Irish water programs, our differentiated high-end infrastructure services all across Canada, and defense infrastructure resiliency work in both United Kingdom and in Australia. I would like to discuss and point out a few point -- a few items on our backlog, which increased to an all-time high of $5.44 billion, as I've mentioned a moment ago, up 15% from last year. We won a whole group or a whole series of Army Corps of Engineers contracts for civil works design, sustainable water infrastructure projects, environmental engineering, emergency response, and flood protection activities, all critical programs that are priorities for the incoming administration. In the Midwestern part of the United States, we won a five-year single award. That means award to just to Tetra Tech for emergency response and preparedness work within that entire region. I'd like to remind you that, while Tetra Tech has more than $25 billion in contract capacity with the U.S. Federal Government, our backlog does not include any factored numbers associated with contract capacity or anticipated awards under IDIQ contracts. So, the work that we have here is contracted, funded by the client and authorized for us to go to work. Nothing else has been adjusted or factored or added into. We don't have that component. Now at this point, I'd like to turn the presentation over to Steve Burdick, who can present the details of our financials in the quarter and particularly our capital allocation programs and priorities for the company. Steve?
