Thanks, Zarak. Good afternoon, and thank you for joining our third quarter 2024 earnings call. Starting on Slide 3, 12 years ago, we embarked on our mission to conquer cancer with data. Roughly two years later, we launched into the late-stage cancer market with our first version of Guardant360 in 2014. In 2021, we launched Guardant Reveal for cancer recurrence and monitoring. And this past quarter, on August 1, we were thrilled to launch our first test into the asymptomatic cancer screening market with Shield unlocking an exciting opportunity to potentially impact millions more individuals across the cancer continuum. As is our practice, I would like to start our call off with a story illustrating the important impact our tests can have on improving patients' lives. A woman was initially diagnosed with left breast cancer when she was 50-years-old. With a family history of cancer, she opted for an aggressive treatment and underwent a double mastectomy. A few years later, she began experiencing hip and lower back pain. After a doctor determined the breast cancer had metastasized, a Guardant360 liquid biopsy test was ordered to determine if the metastasis had any actionable biomarkers. An ESR1 mutation was revealed and she was placed on Elacestrant for therapy. The Guardant360 test report also noted a BRCA2 variant which was later confirmed to be a germline mutation after further testing in a specialized lab. As a result, her family underwent genetic testing and her sister was found to carry the same BRCA2 germline mutation but had not experienced a cancer diagnosis to-date. Her sister chose a prophylactic double mastectomy and oophorectomy as treatment and was found to have occult ovarian cancer. This case highlights the remarkable ability of Guardant360 to provide lifesaving information both for patients with symptoms and for those without. Turning to top-line performance in Slide 4. We continued our strong momentum into the third quarter with total revenue growing 34% to a record $191.5 million. This was driven by another quarter of robust precision oncology revenue, which increased 35% in the quarter supported by significant Guardant360 reimbursement tailwinds and broad-based volume growth fueled by our smart liquid biopsy transition. Turning to Slide 5. Clinical test volume for the third quarter grew 21% year-over-year and 7% quarter-over-quarter, reaching 53,100 tests driven by strength across the portfolio. In particular, Guardant360 performed extremely well in Q3 and grew mid-single-digits sequentially. Furthermore, Reveal continues to see strong growth even with our ongoing careful management of volumes ahead of broader reimbursement. As a reminder, our clinical test volume is specific to our oncology tests, which are Guardant360, TissueNext, Response, and Reveal and does not include screening test volumes from Shield. Q3 was another standout quarter for biopharma with volumes up 40% year-over-year to a record 10,500 tests. I will share some more details in our biopharma progress shortly. Looking more closely at some of the recent highlights within our therapy selection business in Slide 6. In late July, we launched our upgraded Guardant360 LVT and smart liquid biopsy, representing the most significant upgrade to our flagship precision oncology product. Guardant360 is the leading liquid biopsy test for patients with advanced cancer, with industry-leading turnaround time and the improved platform positions us for continued robust growth and share gain. The Guardant360 upgrade expands the number of genes by nearly tenfold, includes all guideline recommended genomic markers for solid tumors, improves the sensitivity for tumor burden detection by a factor of 10 and introduces the first feature enabled by our methylation tech stack and therapy selection. As the performance and richness of the Guardant360 LVT product evolves and we continue to generate clinical data and add features, oncologists will gain an unparalleled view of cancer that we believe will quickly become a new standard of care in the clinical management of advanced cancer patients. Due to this compelling upgrade, we are very pleased that we are already seeing an increase in both breadth and depth of accounts and believe this will continue to drive growth as additional capabilities are unlocked over time. In particular, Guardant360 LVT on smart liquid biopsy was the strongest contributor to year-over-year and sequential volume growth in the third quarter. We also saw continuing improvements in Guardant360 ASPs, which reached $3,000 in the third quarter. Last quarter, we shared the upgrade of our TissueNext test to identify more treatment options for patients with advanced cancer. We have seen strong interest in the expanded panel and are excited to share that effective January 1, 2025, Medicare pricing will increase from $3,100 to $3,500. Following these great updates, I'm excited to share that we again generated positive free cash flow in our therapy selection business in the third quarter. We also announced a partnership with Policlinico Gemelli in Rome, a leading European oncology center to implement on-site processing of Guardant360 CDx tests for therapy selection in advanced cancer patients. This will mark one of the first dedicated liquid biopsy testing facilities housed within a hospital system in Italy. This partnership is significant given there are approximately 400,000 new malignant tumor cases recorded annually across Italy. When implemented, oncologists in Italy will be able to access our tests to make more informed treatment decisions for patients with solid tumor cancers. Finally, results from the SCRUM-Japan GOZILA study were recently published in Nature Medicine demonstrating the significant survival benefits of using Guardant360 CDx to test patients with advanced gastrointestinal cancer. Of the 4,037 patients in the study, 24% received personalized targeted treatment based on Guardant360 CDx and this subgroup survived nearly twice as long as those who did not receive Guardant360 match therapy. This study further solidifies the clinical utility of Guardant360 in guiding effective treatment decisions for advanced cancer patients. Turning to our biopharma business on Slide 7. As I mentioned earlier, we had another record quarter of reported biopharma samples growing 40% year-over-year. Biopharma revenue grew 34% year-over-year in the third quarter. We continue to see a lot of excitement for Guardant Infinity, our newest biopharma offering powered by our smart liquid biopsy platform driven by applications such as improved performance, novel biomarker discovery and signature development. Smart liquid biopsy now represents over 50% of reported samples and new contracts. Importantly, this strength in biopharma is driven by our smart liquid biopsy upgrade and we are still in the early innings of this exciting upgrade cycle. We have recently seen an acceleration of our clinical Guardant360 LVT volume, demonstrating how biopharma R&D testing is an important leading indicator for demand of our clinical oncology tests and in turn, clinical patient testing is a driver for increasing biopharma interest. Taken together, these elements create an important virtuous cycle in the precision oncology space. Finally, we are also seeing increased momentum in China with a strong and growing pipeline of samples. Now shifting gears to Reveal on Slide 8, where we are the leader in tissue-free MRD. Last quarter, we shared that data from our COSMOS colon study looking at Stage 2 and Stage 3 patients was published in the peer-reviewed journal Clinical Cancer Research. This study was also submitted to MolDx for Medicare reimbursement for the CRC surveillance MRD indication and review is ongoing. Beyond CRC surveillance, we have an extensive pipeline of clinical cohorts for establishing validity and utility for Guardant Reveal. This will be instrumental in building compelling evidence that not only supports efforts to expand reimbursement but also has potential to influence changes in practice guidelines. Looking ahead to the remainder of the year, we anticipate submissions for publications that will support potential Medicare reimbursement for coverage and breast cancer, next year we have important clinical validity studies for additional cancers such as lung, pancreatic and gastric. Moving on to Slide 9, we are excited by the demand we are seeing in the tissue-free MRD market and there are multiple near-term inflection opportunities in 2025. We continue to make good progress towards CRC surveillance reimbursement which will improve our ASP. We also remain on track on our COGS reduction initiatives for Reveal. As a reminder, these two milestones will be a significant step towards our long-term goal of achieving greater than 60% gross margins for our MRD business. While we are seeing strong growth and strong market appetite for Reveal, we continue to manage volumes to minimize cash burn and will continue to do so until Reveal is gross margin positive, which we anticipate in 2025. Overall, we are seeing tremendous growth and opportunity around Guardant360, TissueNext, and Reveal largely driven by our recent smart liquid biopsy platform transition. As a result of the great progress we have made this year and are continuing to make, we are more confident than ever that our oncology business will continue to see strong growth over the next few years. With that, I will now turn the call over to AmirAli for an update on screening.
