Thank you Jacob and good afternoon everyone. I will give you an overview of first quarter financial results and provide more color about our revenue, expenses, earnings, and developments on our balance sheet, and then speak about our outlook going forward. Before I get into the details of the financial performance, let me provide a high level view of how the first quarter played out relative to our expectations. In Q1, despite the dynamic environment, team Illumina delivered a quarter of excellent execution. Enabling us to deliver financial results towards the high end of our guidance. Revenue was flat year-over-year at top end of our guidance, and EPS at $0.97 was also towards the top end of the range. Now, let me provide you with details of the financial performance. First quarter revenue of $1.04 billion was down 1.4% year-over-year on an as-reported basis. This included 1.2 points of headwind from foreign exchange and constant currency revenue was roughly flat. Excluding China, revenue was slightly up year-over-year on a constant currency basis. Sequencing consumables revenue of $696 million grew approximately 1% year-over-year, driven by strength in high throughput consumables and the continued transition of high throughput sequencing to X. During the second half of the quarter and correlated with uncertainty around NIH and other research funding levels, we started to see our customers, especially in research and academia, be slightly more conservative in consumable purchases. We estimate this phenomena impacted consumables growth by approximately 1 point year-over-year. Despite this, the sequencing activity on the connected instruments remains strong. We typically see a seasonal increase in ordering activity in Q1, including long-range purchase commitments, leading to building of backlog. We report that as performance obligations in our 10Q. And this ordering activity was stronger than the last couple of years and encouraging sign for the rest of the year. Now about the X transition, which continues to progress well. In Q1, roughly 68% of high throughput gigabases shipped and approximately 43% of high throughput consumables revenue was on the NovaSeq X series. Greater than 80% of high throughput gigabases shipped to our customers in research markets is already on NovaSeq X series. And now over 50% of clinical volumes are also on X. We continue to make progress in the framework we previously disclosed. That in the second half of 2025, approximately 50% of high throughput revenue and approximately 75% of GB shipped will be on the NovaSeq X series. With continued strong underlying sequencing volume growth and strong adoption of X, over time, the price effect of lowered mix of 6K consumables fades away, and a much larger part of high GB growth translates to revenue growth. About sequencing activity, total sequencing GB output on our connected high and mid throughput instruments grew at a rate of more than 30% year-over-year, with robust growth from both clinical and research customers. Sequencing instruments revenue of $109 million was approximately flat year-over-year in Q1, with a higher than expected number of X series instruments shipped in high throughput and the successful launch of the MiSeq i100 in our low throughput portfolio. The clinical transition to NovaSeq X continues as approximately 60% of Xs placed in Q1 were to clinical customers. As you know, early in March, our ability to export instruments into China was restricted. We had in-country inventory to ship our instrument orders in Q1. Sequencing service and other revenue of $142 million was down approximately 5% year-over-year in line with expectations, mainly due to the timing of certain strategic partnership revenues last year related to the AGD consortium. Excluding those, our core services and informatics business grew in the mid single digits. Moving to the rest of Illumina P&L. Non-GAAP gross margin of 67.4% for the first quarter increased 30 basis points year-over-year. Margins were slightly lower than anticipated as we saw a higher mix of instruments business. In addition, we're in the process of rolling out software upgrades for our high throughput instruments, which is improving their performance. As part of this upgrade, we're also pulling forward some of the routine instrument service, which has had a higher cost impact than we had assumed. The vast majority of the upgrades should be completed by Q2. Our manufacturing cost actions continue to make good progress. Non-GAAP operating expenses were $489 million. This reflects our ongoing focus on cost optimization and prioritizing key growth investments. During the quarter, we initiated additional actions to reduce our full-year expenses by $100 million and realized a partial benefit in Q1. Given these cost reduction initiatives, we do not expect the typical seasonal rise in OpEx that occurs post Q1 to repeat in 2025 and expect OpEx to be flat to slightly down for the remainder of the year. The $100 million in cost actions to be realized in 2025 are inclusive of certain stock-based compensation changes and represent over $225 million in total run rate reductions when fully annualized over the next 4 years. Non-GAAP operating margin was 20.4% in Q1. Looking at our results below the line, non-GAAP other expense, which is largely comprised of net interest expense, was $15 million and non-GAAP tax date was 22%. And our average diluted shares were approximately 159 million, 1 million lower than last quarter, driven by share re-purchases, net of dilution from employee equity awards. Altogether, non-GAAP EPS of $0.97 per diluted share came in at the high end of our guidance range. Moving to cash flow and balance sheet items for the quarter. Cash flow provided by operations was a robust $240 million. As a reminder, our annual cash bonus is paid out in Q1. Capital expenditures were $32 million and free cash flow was $208 million. In Q1, we re-purchased approximately 1.73 million shares of Illumina’s stock for $200 million at an average price of $115.74 per share. These re-purchases were completed in February. We ended the quarter with approximately $1.24 billion in cash, cash equivalents, and short-term investments. In gross leverage of approximately 1.8x gross debt to last 12 months EBITDA. Now, moving to guidance for the year 2025. As you may have seen in the press release, we are updating our guidance to reflect the impact of recent changes in the geopolitical environment. We remain confident in the continued strong position of our business and underlying growth in sequencing demand. However, the overall environment remains dynamic and we are providing estimates of known changes as of today and reflecting these impacts in our guidance. As it relates to our business in China, we will now be providing guidance separately for Greater China region. This will allow for visibility into the evolution of our business in China, as well as that the over 95% of our business in 2025 outside Greater China is making significant progress towards our long-term financial targets. Starting with revenue, we are reducing our revenue guidance for Greater China by $125 million at the midpoint in connection with export restrictions on instruments and the projected impact on the remainder of our China business. For the rest of the world, we're lowering our revenue guidance to reflect the effect of 2 items. First, reducing revenue by 2% to 4% quarterly, weighted more towards our research customers due to a constrained funding environment. Partially offset by second approximately 1% of additional quarterly growth driven by clinical customers as we've seen strong instrument placements over the last couple of quarters. The net impact of these 2 items is approximately $60 million over the next 3 quarters. In addition, we're taking pricing actions that provide incremental revenue benefit primarily in the back half of the year. FX favorability relative to our previous guidance adds about $25 million to our projected reported revenue. All put together for the rest of the world, this represents revenue growth of 1% at the midpoint. More about China. We are in active dialogue with the regulatory authorities for a long-term resolution. We're taking a pragmatic view in our guidance and have taken expense actions to offset the impact on our earnings, both for this year and on a cumulative basis going forward. The guide assumes $165 million to $185 million in full-year revenue in the Greater China region, of which $72 million was recognized in Q1, and $60 million is projected for Q2 of 2025. And only $43 million of contribution at midpoint in the second half of the year. To the extent that is a positive resolution in China to represent additional upside to this guidance. Now shifting into our product assumptions. Excluding the Greater China region, we expect sequencing consumables growth between flat and 2%, driven by strong sequencing activity, especially with our clinical customers. For sequencing instruments, we are assuming that our customers will continue to manage their capital investments closely. We expect demand for NovaSeq X instruments to remain relatively constant. And low throughput growth driven by placements of the MiSeq i100, which is being received very well. We expect sequencing instruments excluding Greater China to be roughly flat year-over-year. Now moving to EPS. As you may recall, our revised EPS guidance in March, which maintained EPS of approximately $4.50 took into consideration the reduction in Greater China region revenue. And the impact from our more constrained funding environment, as well as new actions we initiate to help protect our earnings growth. Our new EPS guidance additionally takes into consideration the developments thereafter, and the primary factor lowering our guidance is the new tariff environment. For Illumina, the estimated gross cost of tariffs for 2025 is approximately $85 million. The largest part of this relates to goods shipped from our manufacturing facility in Singapore to the U.S. The remainder relates to parts and subassemblies imported to our manufacturing operations in the U.S., as well as Illumina products sold into China. For Q2, given the inventory effects, we will see a partial period impact, And a $30 million to $35 million impact in the following quarters. Our current guidance does not assume any incremental tariffs, including any counter tariffs from the EU or other countries. We're taking several actions across supply chain optimization, pricing, and enacting other expense measures to fully mitigate the impact of these tariffs. These actions take time, and we will realize an incremental benefit from these actions in 2026. For 2025, we are expecting to mitigate roughly half of this tariff impact and hence reducing the EPS at midpoint by $0.25 from the revised guidance provided in early March. In addition to our ongoing focus on reducing costs, we also plan to continue to repurchase shares under our previously approved share repurchase authorization, which has $1.2 billion remaining at the end of the quarter. These repurchases should provide a small in-year accretive benefit to EPS. Embedded in our FY25 EPS guidance is a contribution from Greater China of approximately $0.35. For comparison, in FY24, we estimate Greater China EPS to be approximately $0.76. Our rest of the world EPS this year at midpoint of guidance would be $3.90 growing at a rate of 15% over similar compared last year. As I mentioned before, the expense actions we triggered in March will give us incremental benefit going forward, and drive earnings growth irrespective of the outcome in China. Bringing it all together, our updated guidance for the year reflects revenue in the range of $4.18 billion to $4.26 billion, a decline in the range of 3% to 1%. And excluding Greater China, a range of flat to 2% growth. We expect a non-GAAP operating margin of approximately 21.5% to 22%, an expansion of 45 basis points at the midpoint versus 2024. The net impact of tariff related items is a reduction of 125 basis points in operating merchant. We're also lowering our non-GAAP tax rate, which is now expected to be approximately 22%. This results in an EPS guidance range of $4.20 to $4.30. Now moving to the second quarter of 2025. For the second quarter, we expect total revenue range between $1.04 billion to $1.06 billion. This includes revenue in Greater China region between $55 million and $65 million. And revenue outside the Greater China region in the range of $980 million to $1 billion or down between 2% and 3% year-over-year, driven predominantly by a decline in certain strategic partnership revenues and the research market dynamics I've spoken to. We are only applying the pricing actions to new orders. Therefore, there will be minimal benefit in Q2. We expect non-GAAP operating margin of approximately 21% and non-GAAP earnings per share in the range of $1 to $1.04, both of which include the estimated $15 million in direct cost impact due to tariffs. Our guide like before implies a stronger half 2 contribution versus half 1, which is premised on both continued improvement in consumables growth with transition of X and also the effect of just triggered expenses and pricing actions whose contributions increase in half 2. In closing, I would like to acknowledge the perseverance and commitment of all the Illumina employees amidst an increasingly dynamic environment. I remain confident in the path forward and Illumina Team's ability to execute towards our near-term and long-term financial targets. Thank you for joining our call today. I will now invite the operator to open the line for Q&A.
