1
The Basics
U.S. life-sciences technology company · large-cap · listed on Nasdaq · headquartered in San Diego, California.
2
The Numbers
Annual revenue in the range of $4–5 billion, almost entirely from selling instruments and consumable reagent kits that keep customers coming back like clockwork.
3
The History

4
The Secret
It dominates the global market for next-generation sequencing with a share north of 80% — a near-monopoly that regulators have scrutinized more than once.
5
The Lore
The U.S. FTC successfully blocked its $8 billion acquisition of a cancer-screening startup, one of the most high-profile antitrust battles in biotech history. It bought the company anyway, then had to spin it back off.
6

If your 23andMe kit, your oncologist's tumor panel, or a COVID variant tracker ever read your DNA, there's a very good chance its sequencer did the reading.
