GPC vs ILMN Comparison

Genuine Parts sells aftermarket automotive parts (60% of sales) and industrial products (40% of sales) in the United States and internationally. The automotive segment primarily acts as a distributor to its network of 9,800 global retail locations, of which about two-thirds are independently owned and operated. We estimate Genuine serves around 6,000 retail locations in the US operating under the Napa Auto Parts brand, with about 80% of end-market sales derived from professional customers. Its industrial segment, primarily operating under the Motion name in the United States, is a leading distributor of bearings, power transmission, and other industrial products to more than 200,000 maintenance, repair, and original equipment manufacturer customers.

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 2024 sales) that enable lower-cost, focused genetic screening with primarily consumer and agricultural applications.
