Francis deSouza
Chief Executive Officer at Illumina
Thank you, Brian, and good afternoon, everyone. Illumina's third quarter was another exceptionally strong quarter with $1.108 billion in revenue, up 40% year-over-year and once again, significantly ahead of expectations. Our customer base continues to expand rapidly. And in the first three quarters of 2021, we added 50% more new customers than in all of 2020 or 2019. Because of this strength across our business, we're raising our full year revenue growth outlook for the third quarter in a row to approximately 36%. This is approximately double the growth rate and $567 million higher than the midpoint of the range we guided to at the beginning of the year. I will talk through the third quarter results for core Illumina as defined as Illumina other than GRAIL, and then I'll turn the call over to Bob Ragusa, the CEO of our GRAIL subsidiary to cover the GRAIL business. Core Illumina revenue was $1.106 billion. Sequencing instrument revenue was up 65% year-over-year, and we exited the quarter with a record instrument backlog, a positive leading indicator for future revenue. Sequencing activity in the quarter was also strong, with sequencing consumable revenue up 45% year-over-year, setting a new record. Our high throughput platform order volume is accelerating. Oncology testing, population sequencing and drug discovery initiatives drove record NovaSeq consumable and instrument shipments. Oncology testing customers represented the highest proportion of NovaSeq shipments for the quarter as large oncology testing labs added to their fleets to support expanded reimbursement for therapy selection testing. Drug discovery is emerging as a new application for high throughput sequencing with opportunities across common diseases ranging from obesity to aging.
Our mid-throughput platforms also drove growth and expanded our installed base. In the third quarter, over 50% of NextSeq 1000 and 2000 placements were new-to-Illumina customers or to customers upgrading from low-throughput instruments. These instruments continue to unlock new applications. Researchers at Tulane School of Medicine are using the NextSeq 2000 for single cell experiments focused on infection and inflammation. The team is working to develop inhaled vaccines for pneumonia and use single-cell RNA-Seq on a NextSeq 2000 to study the immune cells elicited by this vaccine platform in a recent paper published in Science Immunology. Benchtop platforms also saw significant growth year-over-year, with the highest number of MiSeq shipments since Q4 2015. MiSeq, coupled with our COVIDSeq 96-sample assay, is enabling labs around the world to engage in local pathogen surveillance. This quarter, MiSeq placements in both Argentina and Brazil brought COVID surveillance to local communities in conjunction with broader national programs. Now turning to Clinical and Research and Applied segments, Oncology testing, our largest market segment, had another record quarter. Sequencing is becoming the standard of care and therapy selection, which is driving robust demand for Illumina sequencers, and our oncology testing customers are rapidly scaling their fleets in response. Reimbursement for genetic testing for therapy selection continues to expand with over 70% of insured lives in the U.S. now covered for these tests. Additionally, there are over 60 targeted and immunotherapy treatments currently on the market, highlighting the power of comprehensive genomic profiling in matching patients to treatment. TruSight Oncology 500, our research use-only comprehensive genomic profiling assay, had another record quarter, with over 340 customers now using the assay in their labs.
In September, we announced a CDx partnership with Merck to develop and commercialize tests leveraging TSO 500 content and an HRD status based on Myriad's myChoice in patients with ovarian cancer. Approximately 300,000 women around the world will be diagnosed each year with ovarian cancer, the fifth deadliest cancer for women. This partnership will help these patients access additional treatment options with the goal of improving care. In reproductive health, we saw another quarter of strong year-over-year growth. Almost 80% of pregnancies in the U.S. are now covered for noninvasive prenatal testing. And we're seeing additional progress as states begin to incorporate the ACOG guideline revision from last year into their prenatal screening programs. In California, the prenatal screening program is being revised to include noninvasive prenatal testing, and the state has now issued a request for proposal. NIPT is increasingly being incorporated into guidelines outside the U.S. as well. In September, the Italian Ministry of Health issued new guidelines supporting the use of NIPT in a contingent model. With the continued momentum in coverage and guidelines, our end-to-end VeriSeq v2 solution is gaining traction across global markets. Genetic disease testing also posted another strong quarter, as broad reimbursement and compelling clinical utility data drive a shift to whole genome sequencing. This quarter, the results of the groundbreaking NICUSeq trial, co-authored by Illumina scientists were published in JAMA Pediatrics. The randomized time-delayed trial demonstrated that clinical whole genome sequencing drives a twofold improvement in both diagnostic efficacy and change of clinical management for acutely ill newborns.
We are working to ensure that families and NICU patients around the world can access these tests. In the U.S., Michigan recently became the first state to offer rapid whole genome sequencing to acutely ill infants and children regardless of insurance and other states, like California and Florida, are making progress in this direction as well. Outside the U.S., last week, we announced the pilot program in Israel, to implement whole genome sequencing for critically ill infants suspected of having a genetic disorder in neonatal intensive care units. This program will accelerate time to diagnosis for these patients and support rapid clinical decision-making. Turning to our Research and Applied segments. We saw another strong quarter of sequential and year-over-year growth. The 30-plus population genomics initiatives that we support around the world drove growth in the quarter. The accuracy and scalability of our sequencing platforms, combined with our end-to-end solutions, like Illumina Connected Analytics make Illumina an ideal partner for large sequencing initiatives. The value of these population programs is expanding across clinical outcomes, research and drug discovery. This traction is generating significant interest and investment for additional programs like Our Future Health, the U.K.'s largest ever research program focused on developing new ways to detect, treat and prevent disease. Just yesterday, we announced that the Illumina-Connected Analytics solutions are being used by HostSeq, part of the Canadian COVID-19 Genomics network. Our sequencing and bioinformatics solutions will be used to identify biomarkers that can help predict potential risk of serious disease and support the development of novel therapeutics to combat COVID-19.
We anticipate these types of population programs will become increasingly critical to innovation as their findings translate into greater use of sequencing in clinical workflows and actionable data for drug discovery. We're already seeing this with the initial data from the U.K. Biobank as the program concludes. Regeneron is utilizing the U.K. biobank data in multiple ways, including to find more than 500 genes with variant trade associations linked to higher risk of diseases, like hypertension, asthma and liver disease and as part of their data set to create new obesity medicines in partnership with AstraZeneca. And companies like Relay Therapeutics are utilizing genomic data along with AI and machine learning to advance drug discovery. COVID surveillance drove $55 million in sequencing shipments in the quarter, of which $15 million were instrument purchases, as concerns about variants continue to heighten the focus on surveillance efforts. We see the infrastructure for COVID surveillance as the foundation for broader pathogen surveillance to increase around the world. For example, CERI, a new genomics facility in South Africa, was launched this quarter with capabilities to bolster the pandemic and epidemic response across Africa. With resources like this in place, sequencing data from 51 of the 54 countries in Africa, is now available in GISAID. And a total of 50,000 SARS-CoV two genomes have been sequenced, two months ahead of Africa CDC's schedule. Turning to GRAIL. In August, we closed our acquisition, which we believe will help accelerate patient access and affordability for multi-cancer early detection screening. I am delighted to introduce Bob Ragusa on his first call as GRAIL's CEO. Bob most recently served as Illumina's Chief Operations Officer, and he has more than 30 years of experience in genomics. He played a critical role in providing the sequencing systems for the Human Genome Project and was responsible for significantly scaling Illumina's business in more than 140 countries and enabled the first NovaSeq shipments. With his decades of deep expertise, Bob is uniquely positioned to lead GRAIL during a time of extraordinary growth and discovery.
I will now turn the call over to Bob to discuss GRAIL's business updates.
