Thanks, AmirAli. Turning to Slide 12 to review our financial results. Total revenue for the second quarter of 2023 grew 26% to $137.2 million compared to $109.1 million in the prior year quarter. Total precision oncology testing revenue for the second quarter was $125.2 million, increasing 36% compared to $92.1 million in the prior year quarter. As in previous quarters, this increase was driven by strong year-over-year growth in clinical and biopharma volumes. Precision oncology revenue from clinical tests in the second quarter totaled $100.2 million, up 42% from $70.5 million for the prior year quarter. Second quarter clinical test volume was 43,500, an increase of 49% from the same period of the prior year and an increase of 11% or 4,400 tests from Q1 2023. With Guardant360 continues to be the main revenue driver with continued strong growth in lung cancer and a significant uptick in breast cancer. We again saw very strong year-over-year volume growth in both Reveal and TissueNext both growing over 100%. Second quarter Guardant360 ASP continues to be at the upper end of our target range of $2,600 to $2,700. As Helmy mentioned, we had some big breakthroughs in coverage during the past quarter. While this additional coverage will provide tailwinds for our clinical business in the near term, we expect, however, that it will take some time for these upsides to flow through to our clinical ASP due to the length of time it takes to contract with insurers. Blended clinical ASP was approximately $2,300 in line with our expectations. As a reminder, lending clinical ASP will continue to be influenced by both the volume mix between Gardant360, TissueNext, Reveal and response as well as the mix of overall clinical volume between U.S. and international. Precision oncology revenue from biopharma tests in the second quarter totaled $25.0 million up 16% from $21.6 million for the prior year quarter. Biopharma test volume was strong, with second quarter totaling approximately 6,700 tests, up 12% from the prior year quarter. Biopharma ASP in the second quarter was approximately $3,700, which was higher than both last quarter at $3,550 and the prior year quarter at $3,600 due to the product mix. Development Services and other revenue for the second quarter totaled $11.9 million, down $5.2 million or 30% from the prior quarter. This was primarily due to the timing and amount of milestones related to our partnership agreement and the change in companion diagnostics collaboration projects with biopharma customers. Gross profit for the second quarter of 2023 was $83.3 million compared to a gross profit of $72.4 million in the same period of the prior year. Gross margin was 61% compared 66% in the prior year quarter. The change in gross margin was driven by a number of factors. For Precision Oncology, gross margin was 61% in the second quarter of 2023 compared to 63% in Q2 2022. This reduction was due to the change in mix between clinical and biopharma revenue with clinical revenue growing faster than biopharma revenue as well as the year-over-year change in blended clinical ASP from $2,400 to $2,300 due to the increased proportion of clinical volume coming from Reveal, TissueNext and Response. Development Services and other gross margin was 62% in the second quarter of 2023 compared to 86% in Q2 2022. The change in margin was primarily due to the cost of processing Shield LDT samples as part of our market development activities for which we are currently booking minimal revenue. We continue to expect overall gross margin to be approximately 60% for the full year 2023. Operating expenses for the second quarter of 2023 returned $202.9 million compared to $202.7 million in Q2 2022. Net loss was $72.8 million or $0.67 per share for the second quarter of 2023 compared to $229.4 million or $2.25 per share in the second quarter of 2022. The year-over-year reduction in net loss is primarily due to Firstly, our loss from operations reduced from $130.3 million in Q2 2022 to $119.6 million in Q2 2023. Secondly, in Q2 2022, we booked another expense of approximately $100 million to reflect the increase in the fair value of the outstanding shares in our EMEA joint venture, which we acquired in June 2022. Finally, in the second quarter of 2023, we recorded a $64 million unrealized gain related to our strategic equity investment in Lunit, our AI partner for TissueNext, which had its IPO in Korea last year and has seen a substantial increase in its share price over the last few months. Moving on to non-GAAP financial measures on Slide 13. Non-GAAP operating expenses were $180.5 million for the second quarter of 2023, a 2% increase from $176.2 million in the prior year quarter. Non-GAAP net loss was $88.7 million or $0.82 per share for the second quarter of 2023 compared to $101.8 million or $1.00 per share for the second quarter of 2022. Adjusted EBITDA was a loss of $85.2 million in the second quarter of 2023 compared to $94.3 million loss in the second quarter of 2022. Free cash flow for the second quarter of 2023 was negative $100.5 million compared to negative $135.0 million in Q2 2022. We continue to make very good progress in diligently managing our operating expenses and cash burn and we are confident that we will achieve our stated goal of lowering our full year operating expenses compared to 2022 as well as reducing our free cash flow to approximately negative $350 million for the full year. Turning to Slide 14. In May, we completed a successful equity offering where we raised $381 million in net proceeds. This puts us in a very strong position with approximately $1.2 billion of cash, which provides the runway to reach cash flow breakeven, which we are targeting in 2027, '28, 1 to 2 years following shield inclusion in CRC screening guidelines. As we look ahead, we are still on track to achieve cash flow breakeven in therapy selection within the next 3 to 6 months. We'll be able to achieve this milestone as we are now gaining significant leverage from the investments we've made over the last few years to scale our core therapy selection business across commercial, lab and back office operations, and as we've been able to maintain high volume growth and consistently strong ASPs and gross margins for Guardant360. MRD spend will continue to be focused on increasing our market penetration, our technical platform upgrade and developing clinical data to support reimbursement coverage. However, we are confident that the total investment in MRD across the next 5 years can be [indiscernible] from the total contribution generated from therapy selection and from increasing Reveal revenue driven by reimbursement coverage. For screening, we anticipate that the operating loss from our screening pipeline will be approximately $200 million per year over the next 5 years. Over the next 12 months, we will be ready for the SHIELD IVD launch upon successful FDA approval to deliver the next generation of SHIELD with potentially even better early-stage performance and make significant progress on indication expansion to lung and other centers. Investments beyond this will be contingent upon receiving FDA approval and engaged by ongoing commercial success and revenue milestones. Now turning to our outlook for the full year 2023 on Slide 15. We are raising our full year 2023 revenue guidance and now expect revenue to be in the range of $545 million to $558 million, representing growth of approximately 21% to 22% compared 2022. This compares to our previous expectation of $535 million to $545 million. This update reflects the very strong performance of our clinical business in the second quarter. For the remainder of the year, we expect to see a sequential decline in Development Services and other revenue in Q3 due to the timing of project milestones and declining role [indiscernible]. So for the fourth quarter, we expect to see a seasonal uptick in biopharma volume that we've historically seen towards the end of each year. Finally, as just mentioned, we continue to expect 2023 operating expenses to be below full year 2022 and free cash flow to improve to be approximately negative $350 million in 2023 and to consistently improve in the following years. Turning to Slide 16. Our long-term vision is to transform cancer diagnostics through cutting-edge technology, a focus on high-impact opportunities and consistent execution. In the second quarter, we were very pleased to achieve major reimbursement milestones, obtaining national reimbursement coverage for Guardant360 in Japan, and our first U.S. commercial reimbursement coverage Guardant Reveal. Finally, turning to Slide 17. We'll be hosting our first Investor Day on Thursday, September 7 in New York City. We look forward to sharing the deeper dive across our business. Please reach out to
