Thank you, Stuart. And good afternoon, everyone. I'm on Slide 11, covering Q4 performance. As you see, revenues in the quarter were $2.1 billion, that's up 23% versus the prior year and that was driven by growth across both segments and also the LinQuest acquisition we made in late Q3. Adjusted EBITDA was up 21% with margins at 10.7%. Adjusted EPS was $0.91 in the quarter that's up 32% over last year. This exceeded the adjusted EBITDA growth rate despite year-over-year interest headwinds, driven by favorable Q4 tax adjustments that were within our guided range, favorable year-over-year below the line items like mostly FX and a lower share count on repurchases over the past 12 months. On to Slide 12 for the full year. Revenues were strong at $7.7 billion, up 11% versus last year and that's supported by a robust growth across both segments with the additional benefit, of course, of the LinQuest acquisition, which contributed about 2.5 percentage points to the total. Adjusted EBITDA was up 16% with margins increasing 0.5% to 11.2% for the year. This type of positive result, as I always say, starts with excellent program execution and that certainly was the case. Also, as has been the case all year, sustainable tech top line growth of 17% at 20% plus margins is clearly benefiting margins in terms of mix. Adjusted EPS was $3.34, up 15% versus the prior year, generally in line with the adjusted EBITDA increase, offset by higher interest cost. Taxes were largely consistent year-to-year. And as Stuart indicated, revenue and adjusted EBITDA were at the high end of our guidance ranges for the year whereas the adjusted EPS exceeded the top end of our range. Operating cash flows were $462 million for the year with an OCF conversion of 103% to net income. Later in the year, we did make a voluntary payment of $21 million to prefund our 2025 United Kingdom pension obligation. This action was taken in conjunction with seeking a negotiated outcome to enable greater utilization of collateralized cash in the UK going forward with the intention of bumping up our ultimate capital deployment capacity by over $50 million. The prepayment did result in OCF finishing at the low end of our guide for the year, but certainly, we think worthwhile benefits in the long term relative to deployment capacity. On to Slide 13 and our segment performance. I'll first start with Government Solutions, revenues in Q4 increased 20% to $1.6 billion with $150 million in adjusted EBITDA and margins at 9.4%. As you see, all four business units contributed. Defense and intel revenue growth was particularly strong, as you see, up 33% supported by the LinQuest acquisition and also organic growth. Primary drivers here include military space, missile defense and support of advanced technologies, including hypersonics and digital upgrades on various military platforms. International also performed well with an increase of 20% driven by core UK and Australia defense programs and healthy increases in infrastructure work in Australia and the Middle East. As a reminder, the infrastructure area will shift to SDX in 2025 as part of the realignment we discussed in early January. Margins were consistent with last year with normal Q4 seasonality due to lower labor utilization. Book-to-bill in the quarter was 0.9 times. While that isn't unusual for Q4, we'd note significant awards in our favor remain in protests, which hopefully will benefit future quarters. And for the full year, revenues were $5.9 billion, up 10% with adjusted EBITDA of $587 million, also up 10% at a 10% margin, very consistent with last year. On to Slide 14, Sustainable Tech. Within Sustainable Tech Solutions, revenues in the quarter were up 30% with $108 million in adjusted EBITDA and margins at 20.6%. This is quite remarkable given the softness we saw in this market earlier in the year that you might recall. As Stuart suggested earlier, since the summer, demand has increased for our ammonia, energy security and various decarbonization offerings. New projects and on project growth have both contributed significantly. Ammonia technology, program management, consulting services and LNG projects are the main drivers with LNG demand signals particularly picking up after the US election in November. All these same factors drove a strong book-to-bill performance of 1.3 times. And Q4 margins, as has been the case all year, were consistent with our long term targets, 20% plus. For the full year, revenues were $1.9 billion, up 17% with adjusted EBITDA of $398 million, up 18% and at a margin of 21.3%. This marks the third consecutive year sustainable tech has had double digit adjusted EBITDA growth. Book-to-bill for the full year was also a strong 1.1 times. Over to Slide 15 and the balance sheet and capital matters. As Stuart said earlier, we executed a balanced capital deployment plan in 2024, consistent with the course we set at the beginning of the year. We deployed over $1 billion in capital with about 75% of that attributed to the LinQuest acquisition and the rest on returning cash to shareholders primarily through buybacks. With over $1 billion deployed, we ended 2024 with a net leverage of 2.6 times. We expect this leverage ratio to work down as we grow EBITDA in 2025. Now I'd like to provide a little bit of clarity on our capital allocation priorities going forward. Our first priority, as you'd probably expect, is to fund organic growth and also actions to drive operating excellence, that's number one. Number two, we are targeting a leverage ratio below 2.5 times in the current interest rate environment. Growth in EBITDA should get us there quite soon. Our next priority is returning capital to shareholders. Within this, we plan to continue buybacks with bias to do more. Consistent with our growth, we are announcing our Board has approved an increase in full replenishment of our stock buyback authorization to $750 million effective today. We're also committing to maintaining an attractive dividend. As we are tracking to the growth levels consistent with our long term targets, our Board has approved increasing our regular dividend effective this March by 10% to $0.66 per annum or $0.165 per quarter. Since our first increase in the regular dividend in 2020, the average rate of annual dividend increase has been 13%. Finally, we will continue to take a disciplined approach to acquisitions, focused on bolt-ons that have a strong strategic fit, cultural fit, of course, and also attractive financial profile. I'll now turn to Slide 16 and our fiscal 2025 guidance. For fiscal 2025, we're issuing the following. We expect revenue in the range of $8.7 billion to $9.1 billion, representing an increase of 15% at the midpoint. We anticipate adjusted EBITDA of $950 million to $990 million, an increase of 11% at the midpoint. We expect adjusted EPS of $3.71 to $3.95, representing an increase of approximately 15% at the midpoint. And lastly, for operating cash flows, we expect a range of $500 million to $550 million, up 14% at the midpoint. CapEx is expected to be between $50 million and $65 million for the year and our projected effective tax rate is 25% to 27%. Finally, we are expecting phasing of adjusted EPS to be 47% in the first half, 53% in the second half. And with those objectives for 2025, we are certainly progressing well towards the 2027 targets issued in our May 2024 Investor Day. Now our guidance does include key assumptions and I think those are worth highlighting given the current political and economic environment. First, as Stuart said earlier, we believe the types of national security, space and operations programs that we support will continue to be dependent on and demanded by our global customers, including the US government. We are accordingly assuming all material programs we currently support remain in place. If that changes materially, we'll certainly provide an update as appropriate. We believe there is significant probability of a full year continuing resolution for the US government fiscal 2025 but assume funding and tasking, including on-contract growth for mission critical national security operations and modernization programs remains intact. As we have previously communicated, 2025 will be a year in which HomeSafe volumes ramp up considerably. We're assuming HomeSafe continues to ramp but not at the full domestic moves pace for the peak summer season. Our estimated revenue range is $300 million to $500 million for the year. This compares to less than $50 million in 2024, so quite a contributor to growth. We are not contemplating material effects from some of the proposed tariffs. Our current business levels in Mexico, Canada and China are not material. And finally, we're expecting interest rates and foreign exchange rates to remain static from where we are today. So in closing, our plan for 2025 is consistent with the long term targets we set at Investor Day and we do so with confidence, strong growth momentum and a very dedicated global team. With that, I'll turn it back to Stuart.
