Thank you, John. I will cover our first quarter results and provide details on our outlook for the second quarter of 2023. Starting with the first quarter to the revenue of $794 million. As John mentioned, our global team executed well during a challenging period for the company as we work through store operations following the ransomware incident. We estimate the negative impact to revenue was approximately $160 million for the quarter, and our team worked diligently to restore production relative to our initial expectations of at least $200 million impact when we report our fourth quarter results. While recovery has gone well, we've seen a softening of business levels relative to our prior outlook, mainly in electronics and packaging market. As a result, and excluding the impact of ransomware incident, we estimate first quarter revenue would have been lower than our original expectations. As our outlook indicates, we expect softness in overall business levels will continue in the second quarter. However, we see a slight improvement in the second half of the year. Turning to our end markets for the first quarter. As a reminder, the ransomware incident only impacted our Vacuum Photonics Solutions divisions. And therefore, we mostly felt an impact in our semiconductor and specialty industrial markets and to a lesser extent, to electronics and packaging market. We expect to recover approximately 95% of this revenue, remaining 5% largely tied to a transactional catalog business in our specialty industrial market. With as a backdrop, semiconductor revenue was $309 million in the first quarter, declining 38% sequentially and 37% year-over-year primarily due to negative impact of the ransomware incident as well as lower industry demand for semiconductor capital equipment. We estimate the ransomware incident impacted our semiconductor revenue by approximately $110 million in the first quarter. Excluding the impact of the ransomware incident, we estimate semiconductor revenue was down approximately 17% sequentially and 14% year-over-year. We expect to make up approximately 75% of that delayed revenue in the second quarter and virtually all the remaining balance made up in the third quarter. While the first quarter was challenging, we have deep relationships with our customers and work closely with them to restore shipments as quickly as possible. Turning to electronics and packaging market. Revenue was $222 million, a decrease of 17% sequentially and 24% year-over-year, with Q1 2022, representing combined company results. Excluding the impact of foreign exchange and palladium pass-through. First quarter revenue declined 20% on a year-over-year basis compared to combined company results. We estimate the ransomware incident has only nominally impacted our electronics and packaging revenue. We expect this to be substantially recovered in the second quarter. As John mentioned, our chemistry and platelet equipment sales were negatively impacted by the industry slowdown in global electronics demand. Our chemistry revenue declined 13% year-over-year, excluding the impact of foreign exchange and palladium pass-through, reflecting the widely publicized slowdown in unit production volumes across PC, smartphone and server applications. To add some context, going to Gartner, overall PC shipments declined 30% year-over-year in the first quarter. Smartphone shipments declined 12% year-over-year. Because the more factory working days in the second quarter due to the Chinese New Year holiday in the first quarter, we expect electronics and packaging revenue to improve sequentially in the second quarter. In addition, we expect revenue to grow in the second half compared to first half levels. Moving to our specialty industrial market. Revenue in the first quarter was $263 million declining 17% sequentially and 18% year-over-year, with Q1 2022, representing combined company results. We estimate the ransomware incident impact of specialty industrial revenue by approximately $45 million in the first quarter, which we expect to recover approximately $20 million in the second quarter and mostly the remainder in the second half of the year. Excluding the impact of the ransomware incident and foreign exchange and palladium pass-through, first quarter revenue declined approximately 2% year-over-year on a combined company basis. We do not expect to recover a nominal amount of revenue in this part of our business due to the transactional book and turn nature of orders that we generate through our catalog business. In the first quarter, consumables and service revenue across our three end markets comprised 43% of our total revenue. Turning to our margins. We reported first quarter gross margin of 42.2%. The sequential decline of 370 basis points, primarily due to the underutilization of our factory associated with the ransomware incident. First quarter operating expenses were $240 million, a sequential decline of $2 million due to lower variable compensation associated with the reduced revenue levels in the first quarter as well as prudent cost control. First quarter operating margin was 12.1%. Adjusted EBITDA margin was 17.8%, both negatively impacted by lower revenue volumes as well as factory underutilization associated with the ransomware incident. Our integration of Atotech is progressing well and remain on track to achieve our cost synergy target of $55 million within 18 to 36 months post close. We exited the first quarter achieving annualized synergies of $25 million. Net interest expense in the first quarter was $76 million, slightly lower than we anticipated due to favorable interest income. Our tax rate for the first quarter was a benefit of 47% driven by a geographic mix of earnings in the quarter. Net earnings for the first quarter were $32 million or $0.48 per diluted share. Turning to our balance sheet and cash flow. Despite the usual challenges we faced, we exited the quarter maintaining strong liquidity with cash and short-term investments of $880 million with a revolving credit facility of $500 million. We exited the quarter with gross debt of $5.1 billion. Our net leverage ratio exiting the first quarter, which is calculated on a combined company basis was 4.0x based on trailing 12-month adjusted EBITDA. For the first quarter, operating cash flow was $37 million, and free cash flow was $20 million, but negatively impacted by the ransomware incident. Consistent with prior quarters, we had dividend payments of $15 million or $0.22 per share. I'll now turn to our second quarter outlook. We expect second quarter revenue of $980 million, plus or minus $50 million. While we normally do not provide specific guidance by end market, given the different moving pieces such as recovery of ransomware revenue and underlying business levels, we believe a little more granularity would be helpful. With that, in the second quarter, we expect revenue from the semiconductor market to be approximately $400 million, plus or minus $20 million; revenue from electronics and packaging market to be approximately $240 million, plus or minus $10 million; specialty industrial market to be approximately $340 million, plus or minus $20 million. Excluding the impact of ransomware incident for the first and second quarters, we estimate second quarter revenue of approximately $870 million, which represents a sequential decline from the first quarter. We expect this to be primarily a result of softer revenue from a semiconductor market, reflecting declines in wafer fab equipment spending, partially offset by most improvements in revenue of electronics and packaging and specialty industrial markets. Based on anticipated product mix and revenue levels, we estimate second quarter gross margin of 45%, plus or minus 1 percentage point. We expect operating expenses of $255 million, plus or minus $6 million. The sequential increase from the first quarter level is due to higher revenue volumes, timing of annual merit increases, variable compensation and normalization of product spending following a ransomware incident. For the second quarter, we estimate adjusted EBITDA of approximately $223 million, plus or minus $27 million. For the second quarter, net interest expense is expected to be approximately $82 million, reflecting slightly higher interest rates compared to the first quarter, and our tax rate is expected to be approximately 27% for the second quarter. Given the tax benefit we recorded in the first quarter, along with our guidance for the second quarter, we expect our tax rate to be higher in the second half to arrive at an estimated full year rate of 27% and is within our long-term model range. Given these assumptions, we expect second quarter net earnings of $1.13 per diluted share, plus or minus $0.29. In summary, despite unusual challenges, we executed well on driving profitability in the first quarter. Moving forward, we are focused on resuming strong free cash flow generation, realizing acquisition synergies and executing our disciplined strategy of deleveraging our balance sheet. With that, I'll turn it back to the operator for Q&A.
