Here are 1-3 brief analogies for Illumina (ILMN):

• Intel for DNA sequencing: Just as Intel provides the essential processors that power computers, Illumina provides the foundational technology and instruments that sequence DNA, enabling researchers and clinicians to read the genetic code.
• Microsoft for genomics: Similar to how Microsoft creates the operating systems and software that form the backbone of computing, Illumina provides the core platforms and tools (hardware and software) that power the field of genomics.

• Next-Generation Sequencing (NGS) Systems: These are high-throughput instruments used for rapid and accurate DNA and RNA sequencing across various research and clinical applications.
• Sequencing Reagents and Consumables: These include essential chemical kits, flow cells, and other materials required to prepare samples and operate Illumina's sequencing platforms.
• Microarray Systems: These instruments are designed for parallel analysis of genetic variations, genotyping, and gene expression profiling.
• Microarray Consumables: These are specialized chips (arrays) and reagent kits used with microarray instruments for various genomic analysis applications.
• Bioinformatics Software and Solutions: These comprise software tools and platforms for managing, analyzing, and interpreting the vast genomic data generated by their instruments.

Illumina (symbol: ILMN) primarily sells its sequencing and array technologies, consumables, and software to other companies and organizations, rather than directly to individuals.

Given the diverse nature of Illumina's customer base and the fact that public companies rarely disclose specific major customers by name (unless a single customer accounts for a significant portion of revenue, which is not typical for Illumina), it is more appropriate to identify the major *categories* of institutions and companies that utilize their products.

The primary categories of customers Illumina serves include:

• Academic and Research Institutions: This category encompasses universities, government laboratories, and non-profit research centers worldwide that use Illumina's platforms for fundamental research in genomics, genetics, biology, and various other scientific fields.
• Pharmaceutical and Biotechnology Companies: These customers leverage Illumina's technology for drug discovery and development, biomarker identification, genetic screening, and research into new therapies.
• Clinical Laboratories and Healthcare Providers: This segment includes diagnostic laboratories, hospitals, and other healthcare entities that use Illumina's products for clinical applications such as oncology testing, reproductive health screening, rare disease diagnosis, and pharmacogenomics.

Ultima Genomics' ultra-low-cost sequencing platform: Ultima Genomics emerged publicly in 2022 with a sequencing platform claiming a significantly lower cost per gigabase (as low as $1/Gb) compared to Illumina's current offerings. If its technology proves robust, scalable, and accurate in real-world large-scale applications, its drastically lower price point could exert immense pressure on Illumina's reagent pricing, market share, and profitability, especially for high-volume genomics centers. This represents a direct challenge to Illumina's long-standing economic advantage in high-throughput sequencing, akin to a disruptor fundamentally altering the cost structure of an industry.

Rapid advancements and increasing adoption of long-read sequencing technologies: Companies like Oxford Nanopore Technologies (ONT) and Pacific Biosciences (PacBio) are continuously improving their long-read sequencing platforms (e.g., ONT's PromethION, PacBio's Revio). While historically complementing short-read sequencing, long-read technologies are rapidly enhancing accuracy, throughput, and cost-efficiency. As these platforms become more competitive across a broader range of applications, they could increasingly encroach upon traditional short-read strongholds where Illumina dominates, potentially displacing Illumina's technology in areas that value comprehensive genomic information (e.g., structural variants, repetitive regions, epigenetics) as long-read performance metrics approach or surpass short-read's across a wider set of applications.

Illumina (ILMN) operates in the genomics market, with its main products and services centered around next-generation sequencing (NGS) technology and its applications in various fields, including clinical genomics and research. The company itself has provided estimates for its addressable markets.

• Illumina estimates its total addressable genomics market to expand to $120 billion by 2027, globally.
• For 2024, Illumina estimated that the clinical market (global) represents a total addressable market of more than $100 billion.
• The research and applied market (global) has an estimated total addressable market of $25 billion for 2024, according to Illumina.

Further breakdowns of specific market segments in which Illumina participates include:

• The global next-generation sequencing (NGS) market was valued between USD 9.29 billion and USD 23.3 billion in 2024, with projections to reach between USD 27.55 billion and USD 85.4 billion by 2032 or 2033, depending on the source. The North American NGS market held a significant share, for example, 55.65% in 2024.
• The global genomics market, a broader category, was estimated at USD 42.64 billion in 2024 and is expected to reach USD 66.85 billion by 2029. Another estimate placed the global genomics market at USD 27.75 billion in 2023, growing to USD 80.17 billion by 2032.
• The global NGS oncology testing total addressable market is anticipated to grow to $75 billion by 2035. More specifically, the global clinical oncology next-generation sequencing (NGS) market was valued at USD 567.50 million in 2024 and is projected to reach USD 1,421.37 million by 2033. Another source estimates this market at USD 744.4 million in 2025, projected to expand to USD 3.13 billion by 2035.
• The global reproductive genetics market was estimated to be valued at USD 7.31 billion in 2025 and is expected to reach USD 16.67 billion by 2032. Another report valued it at USD 5.1 billion in 2023, with a projection to reach USD 17.2 billion by 2033. The global preimplantation genetic testing market, a segment of reproductive genetics, was valued at US$690.2 million in 2025 and is projected to reach US$1,135.0 million by 2030.

• Accelerated Adoption of NovaSeq X Platform: The transition to and increasing adoption of the NovaSeq X instrument series and its high-throughput consumables are significant growth drivers, particularly within clinical markets. Illumina reported that over 75% of sequencing volume and over 50% of revenue have now transitioned to NovaSeq X high-throughput consumables, with this momentum expected to continue driving near-term revenue growth.
• Expansion in Clinical Genomics and Diagnostic Markets: Strong growth in the clinical market, excluding China, is a primary driver. This is fueled by the broader adoption of comprehensive genomic profiling and the increasing use of sequencing-intensive applications like Minimal Residual Disease (MRD). The clinical market presents a significantly larger total addressable market (TAM) compared to research and is anticipated to grow at a faster rate.
• Strategic Focus on Multiomics and Data Services: Illumina is expanding into new areas such as multiomics and data services. This includes the launch of products like "Illumina Protein Prep" and the introduction of "BioInsight," a new business aimed at leveraging genomic and multiomics data for drug discovery and research. The company's acquisition of SomaLogic is also expected to bolster its multiomics and proteomics offerings.
• Stabilization and Growth in the Research Business: While the clinical sector is currently leading, Illumina anticipates a gradual return to growth in its research business as pricing challenges subside and market conditions stabilize.
• International Market Expansion (excluding Greater China): Despite facing regulatory and export restrictions in Greater China, Illumina is experiencing revenue growth in other international markets, especially in clinical sequencing consumables. The company is strategically managing its global presence to capitalize on opportunities outside of China.
