ILMN vs LII Comparison

Illumina provides tools and services to analyze genetic material with life science and clinical lab applications. The company generates over 90% of its revenue from sequencing instruments, consumables, and services. Illumina's high-throughput technology enables whole genome sequencing in humans and other large organisms. Its lower throughput tools enable applications that require smaller data outputs, such as viral and cancer tumor screening. Illumina also sells microarrays (9% of 2023 sales) that enable lower-cost, focused genetic screening with primarily consumer and agricultural applications.

Lennox International manufactures and distributes heating, ventilating, air conditioning, and refrigeration products to replacement (75% of sales) and new construction (25% of sales) markets. In fiscal 2023, residential HVAC was 68% of sales and commercial HVAC and Heatcraft refrigeration was 32% of sales. The company goes to market with multiple brands, but Lennox is the company's flagship HVAC brand. The Texas-based company is focused on North America after the sale of its European HVAC and refrigeration businesses in late 2023.
