Business Description

At Twist Bioscience Corporation, we work in service of our customers who are changing the world for the better. In fields such as health care, food/agriculture, industrial chemicals/materials and academic research, by using our products, our customers are developing ways to better lives and improve the sustainability of the planet. We believe Twist Bioscience is uniquely positioned to help accelerate their efforts and the faster our customers succeed, the better for all of us. We have developed a disruptive DNA synthesis platform to industrialize the engineering of biology. The core of our platform is a proprietary technology that pioneers a new method of manufacturing synthetic DNA by “writing” DNA on a silicon chip. We have miniaturized traditional chemical DNA synthesis reactions to write over 1,000,000 pieces of DNA (oligonucleotides) up to 500 bases through direct synthesis on each silicon chip, approximately the size of a large mobile phone, reducing by 99.8% the amount of chemicals we estimate would be used per gene as compared to plate-based synthesis. We have combined our silicon-based DNA writing technology with proprietary software, scalable commercial infrastructure and an e-commerce platform to create an integrated technology platform that enables us to achieve high levels of quality, precision, automation, and manufacturing throughput at a significantly lower cost and quicker than our competitors. Building from this platform, we deliver products and services for a wide range of uses and markets. We have applied our unique technology to manufacture a broad range of products, including synthetic genes, tools for next generation sequencing ("NGS"), sample preparation, and both products and services for drug discovery and development, all designed to enable our customers to conduct research more efficiently and effectively. We sell our products and services to a global customer base of more than 3,800, customers across a broad range of industries. We believe our products and services enable a broad range of applications that may ultimately improve health and the sustainability of the planet across multiple industries, including: • healthcare for the identification, prevention, diagnosis and treatment of disease (antibody discovery and optimization technology); • chemicals/materials for cost-effective and sustainable production of new and existing specialty chemicals and materials, such as spider silk, nylon, rubber, fragrances, food flavors and food additives; • food/agriculture for more effective and sustainable crop production; and • academic research for a broad range of education and discovery applications. Background We currently generate revenue through our synthetic biology and NGS tools product lines as well as biopharma services for antibody discovery, optimization and development. In addition, we are leveraging our platform to expand our portfolio to include other products and services to address additional market opportunities. In fiscal year 2025, we served more than 3,800 customers and reported $376.6 million in revenue, including $215.1 million in revenue from the healthcare sector, $93.2 million in revenue from the chemicals/materials sector, $65.9 million in revenue from the academic research sector and $2.4 million in revenue from the food/agriculture sector. 3 Table of Contents Our Markets Synthetic Biology Our synthetic biology products serve life sciences researchers across a variety of healthcare applications including drug discovery, disease detection, enzyme engineering, gene editing and basic academic research. In addition, our synthetic biology products are used for chemical and materials applications including development of synthetic spider silk, nylon, rubber, fragrances, flavors and food additives; for food and agricultural applications including improving crop traits such as adding vitamins or improving drought tolerance, and engineering bacteria to deliver nitrogen at the root of plants. While synthetic DNA has been produced for more than 40 years, the complexities of biology and the production constraints inherent in legacy processes have historically limited the applications and market opportunities for DNA synthesis. Synthetic DNA is the fundamental building block that allows researchers to engineer biology. Synthetic DNA is a foundational product enabling the entire bioeconomy, with synthetic biology alone expected to have a $2-4 trillion global impact by 2030-2040.…
