How the market works today Fertility & perinatal health PGS/D Prenatal testing Neonatal testing Pediatric testing Adult inherited testing Carrier screening Of the up to 10% of the population affected by genetic disease, less than 0.5% receive that information by way of an indication-based screen or test report1 Testing remains largely “event based” with patients accessing the market through discreet entry points Report generally remains isolated from patient’s broader healthcare and long-term health decisions 1Global Genes. “RARE Diseases: Facts and Statistics." Available at https://globalgenes.org/rare-diseases-facts-statistics/.

A large, fragmented and inefficient market (>30) (>20) (~12) (~12) Carrier screening PGS/D Prenatal testing Neonatal testing Pediatric testing Adult inherited testing Preventive screening Fertility & perinatal health Somatic cancer testing PGx 10,000’s of tests

How the market will work in the future Fertility & perinatal health PGS/D Prenatal testing Neonatal testing Pediatric testing Carrier screening A large portion of the population in modernized healthcare systems will have their genetic information managed on their behalf to improve health outcomes for themselves and their families Preventive genetics Access to comprehensive genetic information services at all major market entry points Individuals can access comprehensive genetic information to inform healthcare decisions throughout their lives Adult inherited testing

three basic questions draw people to genetics Starting a family? Diagnosing a disease? Informing my health? Fertility & perinatal health PGS/D Prenatal testing Neonatal testing Pediatric testing Carrier screening Adult inherited testing Proactive Comprehensive solution for clinicians and patients

Clinical Trials Therapeutics Providers Patient Communities Devices Research A lifetime of data across the spectrum of healthcare Fertility & perinatal health PGS/D Prenatal testing Neonatal testing Pediatric testing Carrier screening Adult inherited testing + Comprehensive phenotypic/ Family health history data Comprehensive solution for partners

Scalable, custom, machine-learning software tools enable clinical analysis costs to decline even as assay and panel size increase Capabilities are difficult to retrofit into large incumbent operations Technology integration is tough to justify at smaller scale Moore’s Law The cost of DNA sequencing is decreasing rapidly Law of Finite Genomes Understanding the genetic basis of disease is like a finite puzzle… it’s a reverse engineering problem! Metcalfe’s Law The “Internet of genetics” is emerging A technology fueled business model From sample to answer: custom automation

Executed in the most exacting of industries Many companies deploying technology to lower costs remain naïve about the complexity of biology Applying world-class clinical expertise to results that inform critical healthcare decisions

Building a best-in-class platform Fertility & perinatal health PGS/D Prenatal testing Neonatal testing Pediatric testing Carrier screening Adult inherited testing Depth and breadth have been a key component of our commercial success to date Enhanced content feeds a virtuous cycle of scale, pulling forward value inflection point for our business Breadth depth and scale is essential to lead

Leading with unparalleled depth at unmatched price Most comprehensive testing at the lowest price More genotypic and phenotypic data generated per individual Multiplies growth and value of network data relative to potential competitors 134 ~70 67 30 28 Not all cancer testing created equal

Uniquely capable of serving growing demand Inherited disease Family health Proactive Cancer market estimated to grow to ~2 million tests per year 1.2-1.3 million women in the US with breast and ovarian cancer who qualify for genetic testing didn’t receive it ~1.7 million newly diagnosed cancers per year Cardio, Neuro, Peds estimated to grow over the coming years >90 million Americans living with cardiovascular disease or after-effects of stroke Family health market is already larger than cancer with 4 million live births per year in the US Combined carrier testing, products of conception, cytogenetics, cancer screening into one NGS platform Aggregate market is enormous for family health Proactive Health market estimated to grow to over 10 million per year Up to 10% of the population is affected by a genetic disease ~330 million US population is the total addressable market

Emergence of new industry Comprehensive genetic health information service to lead new era of healthcare Build a genome management infrastructure Make genetic testing more affordable and more accessible Build partnerships with industry peers to increase utilization of genetic testing Share genetic information on a global scale to diagnose more Genome Network Genetic Testing Genome Management Make acquisitions that expand test menu content and services to open new markets patients correctly and bring therapies to market faster
