Fun facts about ILLUMINA, INC.

Quirks, history, and lore behind ILMN — the kind of stuff that makes a stock memorable.

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
Founded in 1998, it pivoted early into a technology that would eventually make the Human Genome Project's price tag look laughably expensive — driving sequencing costs from millions to hundreds of dollars.
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
The Giveaway
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.

What's Driving ILMN's Business? Latest 10-Q Breakdown

✓ 28/28 datapoints verified

AI-extracted from ILLUMINA, INC.'s 10-Q filed 2026-07-31 — Q2 FY2026 (quarter ended June 28, 2026) and YTD 2026 (six months ended June 28, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.

Illumina reported Q2 2026 revenue of $1,159M (+9% YoY) and YTD 2026 revenue of $2,251M (+7% YoY), with operating margin improving to 20.2% YTD 2026 vs. 18.0% YTD 2025, driven by NovaSeq X demand and the January 2026 SomaLogic acquisition.

Biggest Revenue Drivers

Product revenue$1,899M+6% YoY

Increased primarily by greater demand for high-throughput consumables from NovaSeq X installed base growth and higher NovaSeq X and MiSeq i100 instrument shipments.

Service and other revenue$352M+15% YoY

Increased primarily due to SomaLogic acquisition revenue in January 2026, and growth in development/licensing agreements and informatics solutions.

Biggest Revenue Drivers

Total revenue: $2,251M+7% YoY

Product revenue$1,899M+6% YoY

Increased primarily by greater demand for high-throughput consumables from NovaSeq X installed base growth and higher NovaSeq X and MiSeq i100 instrument shipments.

Within Product revenue

Consumables$1,649M+4% YoY

Growth in high-throughput consumables supported by continued NovaSeq X installed base expansion, partially offset by decreased mid-throughput consumables.

Instruments$250M+17% YoY

Higher NovaSeq X and MiSeq i100 shipments drove instrument revenue growth.

Service and other revenue$352M+15% YoY

Increased primarily due to SomaLogic acquisition revenue in January 2026, and growth in development/licensing agreements and informatics solutions.

Largest Expense Items

Cost of revenue$760MNot separately disclosed

Higher tariff costs, increased instrument sales mix, rising memory and freight costs, and lower-margin SomaLogic revenue, partially offset by decreases in field service and warranty costs.

Selling, general and administrative$545M+9% YoY

Increases in employee-related compensation, legal expenses for IP litigation, ERP system upgrade costs, partially offset by decreased restructuring charges and increased government incentive benefits.

Research and development$492M-1% YoY

Decrease primarily due to lower restructuring charges and increased government incentives, partially offset by lab supply and employee compensation increases.

Margins: Gross margin improved to 66.2% YTD 2026 from 65.6% YTD 2025, primarily due to a $23M intangible asset impairment in Q2 2025; excluding that, gross margin declined due to higher tariffs, shift toward lower-margin instruments, memory chip costs, and SomaLogic contribution. Operating margin expanded to 20.2% from 18.0% due to strong gross profit growth of $113M, offset by $37M increase in operating expenses.

Watch Items from the Filing

Greater China revenue declined $27M YTD 2026 due to inclusion on China's unreliable entities list; ongoing trade and regulatory uncertainty may further impact sales.
Tariff exposure remains significant; company incurred substantial IEEPA-related tariff costs since April 2025 and began recovery process, but timing and amount uncertain pending court developments and administrative actions.
SomaLogic contingent consideration of $37M as of Q2 2026 (reduced to $7M after $30M buyout on July 27, 2026); contingent on 2026 revenue targets and NGS kit royalties through January 2036.
Shareholder derivative litigation consolidated in Delaware regarding GRAIL acquisition; Icahn Partners case settled with no payment, but City of Omaha, City of Roseville, and Pavers cases remain with motions to dismiss briefing ongoing.
