Thanks, Rex, and good evening, everyone. I'll begin with total company financial highlights on Slide 4 of the earnings presentation. Fourth quarter revenue was $886 million, up 19% year-over-year as strong growth in commercial operations was partially offset by a modest and expected decline in government operations. Organic revenue was up 4%. Adjusted EBITDA was $148 million, up 13% year-over-year, attributable to robust double-digit growth in commercial operations and lower corporate expense, which were partially offset by lower government operations. Adjusted earnings per share were $1.08, up 17% due to strong operating performance and a higher contribution from nonoperating items of approximately $0.05. Our adjusted effective tax rate in the quarter was 19.5%, which was below our full year tax rate of 20.4% due to timing of R&D tax credits. In 2026, we expect our tax rate to be slightly higher at approximately 22% as growth in our commercial power and Kinectrics businesses will result in a greater percentage of international earnings. Fourth quarter free cash flow was $57 million and full year free cash flow was $295 million, up 16% compared to last year, inclusive of 17% operating cash flow growth. Capital expenditures in 2025 were $185 million, 5.8% of sales. In 2026, we expect CapEx to be about 6% of sales as we continue to invest in the business to meet our commitments with our government customers and to support the growing demand in our commercial markets. During the quarter, we also completed a $1.25 billion convertible debt offering with a 0% coupon. In connection with the offering, we entered into a capped call transaction, which essentially increased the conversion price to over $396. Funds from the transaction were used to repay balances on our credit facility and term loan, which we in turn renegotiated with more favorable terms and increased capacity. This was a highly opportunistic transaction for BWXT. We reduced our cost of debt, lowered our interest expense, enhanced our financial flexibility and increased our liquidity, which stood at $1.7 billion at the end of the year. Moving to the segment results on Slide 6. In Government Operations, fourth quarter revenue was down 1% as expected, with growth in special materials and contribution from AOT being offset by lower microreactor volumes and long lead material procurement for naval propulsion equipment, the latter of which was a benefit to our results in the first 3 quarters of the year. Adjusted EBITDA in the segment was $111 million, resulting in an adjusted EBITDA margin of 18.8%. Our quarterly adjusted EBITDA margin was slightly lower than the full year result of 20.4% due to mix as newer projects in this segment began to ramp. Turning to commercial operations. Revenue was up a robust 95%, driven by 31% organic growth with strong growth in both commercial power and medical and contribution from Kinectrics. This reflects both accelerating organic momentum and the strategic expansion of our commercial capabilities. Adjusted EBITDA in the segment was $44 million, up 87% from last year. Adjusted EBITDA margin was 14.9%, a notable improvement from last quarter. In 2026, we expect the Commercial Operations segment adjusted EBITDA margin to increase by roughly 100 basis points as higher revenue and more normalized mix is partially offset by continued growth investment as we scale the business for the future. Beyond 2026, we expect growth investment to be less of a margin headwind as continued investments are offset by additional revenue growth. Turning to our 2026 guidance on Slide 10 and 11 of the earnings presentation. From an operational standpoint, our guidance is largely in line with the preliminary outlook we provided in November. We expect revenue of approximately $3.75 billion, up high teens compared to 2025. In Government Operations, we expect approximately low to mid-teens growth with over half coming from the defense fuels and HPDU contracts. In commercial operations, we expect approximately 25% growth, driven by low double-digit growth in commercial power, high teens medical growth and a full year of contribution from Kinectrix. For adjusted EBITDA, we are guiding $645 million to $660 million, up low to mid-teens compared to 2025. In Government Operations, we expect margin to be slightly lower given the significant revenue contribution from new programs, which begins at a lower initial profit recognition and expands over time as execution milestones are met and contract risk is reduced. In commercial operations, we expect margin to trend back toward historical levels, as I previously discussed. Regarding the cadence of operating earnings, we anticipate our results will be slightly more back half weighted than usual with about 55% of full year EBITDA anticipated in the second half. This will largely be reflected in first quarter results with a return to more normal seasonality in second quarter. In the first quarter, while we expect solid year-over-year organic revenue growth, EBITDA is likely to be flat to slightly higher in both segments due to seasonality, short-term impacts of mix and ramping of new programs. In Government operations, this will likely translate to first quarter EBITDA being roughly flat year-over-year, yielding a margin that is slightly below the full year guidance rate. And in Commercial Operations, margins are expected to start the year well below our full year guidance before improving sequentially each quarter throughout the remainder of the year, reflecting program timing and mix. These assumptions lead to non-GAAP earnings per share guidance of $4.55 to $4.70, up mid- to high teens, driven largely by growth in both segments. With a modest contribution from nonoperational items as lower interest expense is partially offset by a slightly higher tax rate and share count and lower pension and other income. From a quarterly perspective, while we anticipate earnings per share to follow a similar pattern to our operating earnings with first quarter EPS relatively flat compared to last year, we are highly confident in delivering our full year earnings growth outlook. Finally, we expect free cash flow of $305 million to $320 million, inclusive of low to mid-teens operating cash flow growth, in line with our adjusted EBITDA growth outlook. Importantly, this level of cash generation supports both continued reinvestment and long-term shareholder value creation. Overall, we see 2026 as another year of meaningful operational growth for BWXT. We've strengthened our balance sheet, expanded our commercial platform and positioned the company for continued margin improvement and cash generation. Our focus remains on disciplined execution, prudent investment and long-term shareholder value creation. With that, I will turn it back to Rex for closing remarks.
