Thank you, Tom, and good morning to each of you on the call. I'll continue the prepared remarks on Slide 8, outlining our financial performance. First quarter total revenue was $258 million, an increase of 28% versus last year's first quarter. Organic revenue growth was 3%, in line with our expectations and aligned with what we communicated in February. First quarter adjusted EBITDA was $54 million or 16% better than last year. As foreshadowed back in February, margins contracted in the quarter, reflecting margin dilutive M&A, one-timers in Q1 of the prior year and a mix shift in the legacy Nuclear & Safety segment, mainly related to our sensing business. We utilized approximately $16 million of our $100 million share repurchase program in the first quarter to buy back approximately 700,000 shares. This is consistent with last year's first quarter to offset the dilutive impact from our annual stock-based compensation program. We generated $11 million of adjusted free cash flow in the quarter. Q1 is historically our lightest cash flow generation quarter. Cash generation around our project business can be lumpy, and that is what we saw in Q1 with less project inflows than a year ago. In the quarters going forward, we have line of sight to a much more robust cash generation profile and a better working capital dynamics. Lastly, as Tom outlined, orders in the first quarter were strong with growth coming from both segments. Slide 9 has the details. Order performance was the highlight of the quarter. Absent any M&A-related order growth, core orders grew nearly 20%, reflecting growth in both segments. Total orders, including a $47 million contribution from Paragon and Certrec, grew 42% in the quarter to $288 million. In Nuclear & Safety, orders grew across all three end markets, nuclear power, labs and research and defense and diversified. In Nuclear Power, growth primarily reflects two sizable installed base orders within the U.S. operating fleet and a large SMR order. Within Paragon, we booked an incremental large order within the U.S. installed base. The approximately $35 million SMR-related order we were awarded in April will show up in the Q2 orders number. Labs and research orders grew primarily out of Europe despite comping against the $5 million DOE order from last year. One thing I would point out at Paragon is we saw strong DOE-related order activity in the quarter. Our DOE pipeline across the company is very strong. Lastly, defense and diversified orders grew in the quarter, thanks to a radioactive waste handling order, which was part of our large opportunity pipeline. In the Medical segment, order growth primarily reflects the radiation-hardened cameras order within the RTQA end market. That gives us good backlog in that new product for the next 3 years. Slide 10 provides the latest update to our large opportunity pipeline. Two of the 5 large opportunity orders are Paragon related. In the first quarter, we won the first part of an SMR order, part of a radioactive waste handling order in our defense and diversified end market a Paragon large battery qualification order within the installed base and a large medical order for radiation-hardened cameras from our RTQA business. Interestingly and importantly, both the RTQA and battery orders were not in our pipeline at year-end, which tells you how dynamic the environment continues to be. Separately, in April, we were awarded the first part of another large Paragon SMR order. The rest of the pipeline remains active and continues to represent a significant opportunity for the company, including the remaining components of the three partial orders I mentioned. Before I dig into the quarter's financial results, let me spend a moment detailing the Nuclear Power end market on Slide 11. Nuclear Power orders, excluding M&A, grew 15% in the first quarter, including the large partial SMR order. SMR orders continue to impress. We booked approximately $15 million of orders in the quarter, followed by the $35 million large opportunity we were awarded in April. Momentum continues within this segment of Nuclear Power. Let's get into the quarterly financials beginning on Slide 12. Consolidated first quarter revenue grew 27.5% to $258 million. Approximately 21% of the 27.5% growth was attributed to acquisitions, primarily Paragon. Organic revenue growth of 3% was in line with expectations. Recall, on our February earnings call, we noted that we expected organic revenue growth to be in the low single digits for the first quarter. First quarter adjusted EBITDA was $54 million or 16% better than last year's first quarter. Also, as foreshadowed on our February earnings call, adjusted EBITDA margins contracted. This was primarily due to the margin dilutive impact from M&A as well as some mix impacts, coupled with one-timers in the legacy business. We expect to see margin expansion in the next 3 quarters within the legacy business, offset by Paragon. Adjusted EPS totaled $0.10 per share in the quarter. In 2026, we are now including stock-based comp in our adjusted EPS calculation. Last year's adjusted EPS would have been $0.08 per share, using a similar methodology to the one put in place for 2026. We have an adjusted EPS reconciliation slide in the appendix that has the details for your model. Turning to the Nuclear & Safety segment on Slide 13. First quarter revenue was $186 million, up 39%. Organic revenue was 2.6%, better than our expectations of flat year-over-year noted in February. A few things of particular interest in the first quarter. First, Nuclear Power-related revenue, excluding M&A, increased 4% versus last year. I would note that for the first quarter, we were comping 18%. We saw growth in both our installed base markets of North America and Europe, while this was offset by less new build revenue in Asia, mainly China and Korea. We still expect to see double-digit revenue growth in the Nuclear Power end market for the full year. Second, we are seeing SMR-related revenue accelerate. This accounts for 2% of total Mirion revenue and is expected to increase to greater than 3% of total Mirion revenue by year-end. Third, we saw better-than-expected labs and research end market organic revenue growth, thanks to strong performance out of North America. Fourth, in our defense end market, we saw higher NATO and U.S. military and civil defense revenue. As a reminder, the defense end market can be lumpy, but activity has certainly picked up. Adjusted EBITDA grew nearly $8 million or 19% to $47 million. As we've already discussed, Nuclear & Safety adjusted EBITDA margins contracted. Half of the contraction was M&A related. The other half was mostly due to mix shifts inclusive of the sensing business, the number of one-timers in the prior year and some mix more broadly within our North America business. Lastly, it is worth noting that we were comping over 300 basis points of margin expansion in Q1 2025, the largest of any quarter in 2025 for this segment. Now let's move to the Medical segment on Slide 14. First quarter revenue was $72 million, up 5%. Organic revenue growth was approximately 4%, in line with the expected mid-single-digit organic revenue growth noted on the February earnings call. Our RTQA end market posted double-digit organic revenue growth, driven by an easier comp lapping last year's ERP implementation headwinds, favorable software performance and a month's worth of production from the large camera order we received. In Nuclear Medicine, we expect much of the organic revenue growth to occur in the back half of the year. Meanwhile, our Dosimetry Services end market posted a slight reduction in organic growth. This business had a difficult comp due to a large hardware order last year, which we have discussed before. Excluding this, our core Dosimetry Services organic revenue would have grown low single digits in Q1. Medical segment Q1 adjusted EBITDA was $25 million or 6% better than last year. As expected, margins expanded in the quarter, reflecting operating leverage and pricing tailwinds. Turning to adjusted free cash flow on Slide 15. We generated $11 million of adjusted free cash flow in the first quarter. The difference versus last year is primarily due to timing affecting net working capital. While net working capital was a large use of cash in the quarter, we saw the structural enhancements we made to our balance sheet bear fruit in the quarter via the interest expense line. We remain on track for our full year adjusted free cash flow guidance and believe Q1 marks a trough. We continue to see large opportunities for improvement in AR, inventory and our project cash flows. More broadly, on 2026 guidance on Slide 16. Everything remains unchanged from our February earnings call disclosures with the exception of a small adjustment to adjusted EPS to account for the onetime CEO retention grant of performance vesting stock options disclosed earlier this month. Before we open the call to your questions, I'll provide some details about second quarter expectations. First, on orders. Second quarter orders will be higher compared to the first quarter. We expect another quarter of strong order growth, where sequentially from Q1 to Q2, we expect to see 15% to 20% order growth. Consolidated second quarter organic revenue growth is expected to be in the low single digits. This is also the case in each operating segment. As a reminder, on the top and bottom line, we shipped quite a bit of product in the second quarter of 2025 into China before the tariffs went into effect. So this quarter has that as a headwind. Consolidated adjusted EBITDA margins should be relatively flat versus Q2 2025. Nuclear & Safety segment adjusted EBITDA margins should also be relatively flat despite the margin dilutive impacts from the Paragon acquisition. Excluding Paragon's margin dilutive impact, Nuclear & Safety segment adjusted EBITDA margins are expected to expand. Regarding Paragon, we expect second quarter revenue to be slightly lower than first quarter, but still posting double-digit revenue growth versus last year. We maintain our prior expectations of approximately 25% full year revenue growth for Paragon, and we continue to expect low 20s EBITDA margins. Lastly, Medical segment margins should expand slightly. Recall, Medical segment margins in last year's second quarter expanded almost 300 basis points. So we're lapping another tough comp in that segment. With that, let's open the call to your questions.
