Thanks, Jamie, and good morning, everyone. I will pick up on Slide 4. As with all meetings at KBR, we begin today with a brief Zero Harm moment. Last week, we published our 2024 sustainability report, and I would like to highlight several key achievements from this most recent publication. We are pleased to report an industry-leading health, safety security incident rate and over 93% zero harm days. Additionally, 38% of KBR's fiscal 2024 revenue equivalent to $2.9 billion was allocated towards sustainability initiatives, marking an increase from the $2.5 billion in the previous year. Furthermore, KBR has established and approved science-based near-term targets that align with our net zero objectives. These accomplishments distinguish KBR within our industry. For the third consecutive year, we have been awarded MSCI's top AAA rating, and we recently received a B- rating from ISS, ESG Corporate. This is a recognized prime rating and at the top of our peer group. These highlights represent only a portion of our progress, and I encourage you to review the full sustainability report, which is available on our website via the QR code. Now on to Slide 5. Let me start today with revenue. Revenue was flat in the quarter year-on-year and up 5% year-to-date from the prior year. While we are really encouraged by a strong book-to-bill of 1.4x for the quarter, this was back-end weighted with little conversion to revenue in Q3. In MTS, as you know, we have significant contracts awarded to us, which are still under protest and conversion remains uncertain with the government shutdown environment. In STS, we faced several headwinds in the first half of the year. LNG project development was delayed by prior administration decisions, oversupply in petrochemicals led to multiple project cancellations and delays. Middle East unrest caused temporary pauses and new tariffs delayed investment. Additionally, a market shift towards energy affordability resulted in most of our green technology prospects being postponed or canceled. With that in mind, however, the STS business has proven remarkably resilient. We have replaced the revenue reductions caused by the above headwinds with geographical expansion. We talked about the Middle East and countries like Iraq last quarter, and we've really doubled down in the better markets like LNG, ammonia for fertilizer, energy affordability and circularity. STS book-to-bill in Q3 was pleasing. But as I said a moment ago, this was back-end weighted, and Mark will discuss the short-term impact of this in a moment. The recent bookings, we think, show a shift in momentum, which we expect to continue in Q4, setting us up nicely heading into 2026. Importantly, we focused on what we can control. We delivered excellent bottom line performance in Q3 across all metrics. Adjusted EBITDA margins were up more than 100 basis points year-on-year at 12.4%, delivering an adjusted EBITDA of $240 million, up 10%. This was from a combination of delivery excellence, strong commercial management and prudent cost control. This translated into an adjusted EPS of $1.02, an increase of 21% year-over-year. Now cash, really important. Cash was the standout in the quarter with conversion over 130% year-to-date, generating operating cash of $198 million in the quarter and $506 million year-to-date. And this takes us into a guided range for the full year, a terrific performance. Thirdly, our book-to-bill in the quarter in both segments was solid, and we continue to be well positioned in key markets with a robust pipeline of opportunities awaiting award. In addition, we have several new wins in areas of strategic importance, more on this in a moment. In such volatile times, the quality of the work under contract and the pipeline are clear indicators of future earnings potential and thus worth more detail. Fourth, we'll remind you that circa 40% of KBR's group revenue and over 60%, 6-0 percent of adjusted EBITDA has 0 exposure to the U.S. government spending budgets and of course, risk related to the shutdown. Within MTS U.S., the majority of our portfolio, as we've discussed many times, is comprised of mission essential operational work, many of which are well-funded multiyear programs. This provides short-term resilience to the government shutdown, and Mark will provide additional details in the outlook. Fifth, we returned more than $120 million in capital to shareholders this quarter while managing leverage responsibly. Finally, work to progress the spin-off is on track, which I'll discuss in more detail later. On to Slide 6 and some new contract wins. We were pleased to announce a number of new contract wins during the third quarter, a few of which I will highlight. Let me start with MTS. We were awarded a $2.5 billion ceiling value base period contract, plus another $1 billion in option value to support astronaut health and human performance during space missions. This achievement represents our largest recompete this year. Human performance and space remains a key strategic area for NASA over the medium term as demonstrated by the significantly higher ceiling value awarded to us. Our booking value for this contract, to be clear, was below $1 billion, which is more consistent with the current run rate. MTS also secured several strategic contracts with the Air Force Research Laboratory, utilizing our expertise in cybersecurity, trusted microelectronics, electronic warfare, digital forensics and sensing. These technological solutions are used to enhance situational awareness and therefore, strengthen decision-making for our military customers, really important stuff. MTS was also recently awarded a contract for the U.S. Space Force to deploy our groundbreaking collaborative digital engineering ecosystem called Integration Accelerator to enhance Space Force decision-making and accelerate capability deployment. The design implementation for collaborative environment or DICE, together with Integration Accelerator will focus on establishing a state-of-the-art testing and training environment for the U.S. Space Force at its national headquarters. Moving to STS. We continue to be a strategic partner for Basra Oil Company and have extended our current contract 2 more years to continue to perform engineering, procurement and construction management services for the Majnoon oil field in Iraq, and that's one of the country's most strategic assets. STS was also awarded a contract by the Abu Dhabi Transmission Company called TAQA for program management consultancy services to manage the overall execution of the power and water transmission networks across multiple locations in the UAE to enable data center expansion. STS was also awarded a front-end engineering design contract for Kuwait Oil Company. That's for their heavy oil program, another strategic energy security project for the nation. Last but not least, STS was awarded the FEED contract for the Abadi onshore LNG project in Indonesia. This is a complex project, which has critical significance to national energy security and demonstrates KBR's long-standing track record in excellence in LNG. The book-to-bill for the group in the quarter was 1.4x with a trailing 12 months of 1.0x. Backlog and options now stand at more than $23 billion, and this value represents a 13, 1-3% increase since prior year-end and is the highest backlog and option value in KBR's recent history. And I think this clearly provides for the growth capacity contemplated in our long-term view. On to Slide 7. Next, I'll update you on our pipeline and award trends in both segments. Currently, MTS has $18 billion in bids pending award with over 75% representing new business opportunities. Some contracts such as HHPC have recently been awarded, while new proposals have also been submitted and are awaiting decisions. Although the government contract environment did show some signs of improvement in Q3, the shutdown has brought decisions to a halt, so more delays should be expected. In addition to the $18 billion, there are now $3 billion in contracts awarded to KBR as the winning bidder that remain under protest, and that's an increase of 50%, 5-0% from the previous quarter. The major addition was a classified program in INDOPACOM, which is now included in this category. Overall, this year, both the amount bid and the amount won have increased compared to the previous year's levels at this time. While short-term conversion has been a challenge, matters under our control to grow backlog, options and pipeline have progressed well, and we remain confident in our strategic positioning moving forward. MTS itself delivered a 1.4x book-to-bill in the quarter and ended with $19.7 billion in backlog and options, and that's an increase of almost $2 billion versus the prior quarter. STS delivered a 1.2x book-to-bill, excluding LNG in the quarter and ended with $3.7 billion in backlog. We currently have over $5 billion in our near-term bid pipeline, and that excludes major LNG. This is up from the second quarter when we reported $4.5 billion. This is a 20% increase for our base business. You will also recall last quarter, we saw an anticipated circa $1.5 billion in awards expected to be approved during the second half of the year. In this quarter, we secured over $800 million in bookings, which I believe demonstrate the value of the STS global business model, our deep customer relationships and our laser focus on delivering value-add solutions to solve our customers' challenges. With that, I'll pass it over to Mark. Mark?
