NASDAQ: ILMN · Life Sciences Tools & Services

Illumina, Inc.

Illumina, based in San Diego, is a global leader in DNA sequencing and array-based tools for genetic and genomic analysis. It sells sequencing instruments such as the NovaSeq X and, mainly, the consumables (reagents and flow cells) used on them, plus services, to research labs, hospitals and clinical testing companies. In 2025 consumables were $3,227 million of $4,343 million revenue, instruments $482 million and service and other $634 million. Illumina bought cancer-test developer GRAIL in 2021 and, after antitrust challenges, spun it off in June 2024; GRAIL-related impairments caused large losses in 2022–2024. It returned to profit in 2025 (net income $850 million, diluted EPS $5.45). China barred its instrument exports from March to November 2025, and Greater China revenue fell to $243 million. In January 2026 it bought proteomics company SomaLogic for $350 million.

The rest of this page — including the financial table and ROIC vs. WACC — uses fiscal year-end prices. These are reference figures, not a judgment of whether the stock is cheap or expensive.

    Revenue grew +6.0% a year over 5 years (strong growth)

    From $3.24B in FY2020 to $4.34B in FY2025. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.

  • ―

    Operating margin held roughly flat: 17.9% → 18.6%

    How much operating profit is left per $100 of revenue. It moved +0.7 points over 5 years — pricing power, cost control, and product mix all show up here.

  • ―

    Equity ratio is 41.0% (a middling level)

    The share of total assets funded by equity rather than debt. 50%+ is often read as low bankruptcy risk, though the right level varies by industry (real estate and leasing run lower, for instance).

  • ▲

    Free cash flow was positive in 6 of 6 years

    Operating cash flow minus capital expenditures: the cash left over after funding the business’s own investment, available for dividends, buybacks, acquisitions, or debt paydown. A negative year can mean heavy investment, or weak core earnings — worth distinguishing.

  • ▼

    ROE averaged -7.1% over 6 years (latest: 33.4%)

    How much profit was generated on shareholders’ equity. Roughly 10%+ is often cited as solid for a U.S. company, though this varies a lot by industry and capital intensity.

Is ROIC above WACC?From SEC data

ROIC (the return on money invested in the business) above WACC (the cost of raising that money) means the company is creating value. WACC is an estimate, so its assumptions can be adjusted below.

ROIC (FY2025)

14.3%

formulaoperating income × (1 − tax rate) ÷ invested capital × 100 *invested capital = interest-bearing debt + total equity (average of beginning/ending)

e.g.$807M × (1 − 19.5%) ÷ $4,537M × 100 = 14.3%

termsOperating income · Effective tax rate · Invested capital · Interest-bearing debt · Total equity

WACC (this site’s estimate)

10.14%

formulacost of equity × equity weight + cost of debt × (1 − tax rate) × debt weight

e.g.Equity weight: $20.65B ÷ ($20.65B + $1.99B) = 91.2%

e.g.Debt weight: $1.99B ÷ ($20.65B + $1.99B) = 8.8%

e.g.WACC: 10.7% × 91.2% + 5.1% × (1 − 19.5%) × 8.8% = 10.14%

termsCost of equity · Equity weight (E/(D+E)) · Cost of debt · (1 − tax rate) · Debt weight (D/(D+E)) · Market capitalization

How firm is this? With the equity risk premium ±1 point and beta ±0.2, WACC runs 8.4%–12.3% and ROIC − WACC runs +2.0 to +6.0 points. The sign holds across this range. This describes the latest year and does not predict future value creation.

What the price implies (DCF)From SEC data

A company's value can be written as its free cash flow divided by (cost of capital − perpetual growth). Working that backwards from the market's valuation shows how much growth the share price assumed — compared here with the company's actual past growth.

Growth the price implies (price on 2026-11-04)

7.5%

Perpetual FCF growth: g = r − FCF ÷ EV = 10.1% − 2.6%

Past FCF growth (FY2020–FY2025)

+0.9%

Compound annual rate, 5 years

Past revenue growth (FY2020–FY2025)

+6.0%

Compound annual rate, 5 years

Inputs (FY2025): free cash flow $931M (operating CF − capex); enterprise value $35.82B = market cap $35.47B (latest close, 2026-11-04) + debt $1.99B − cash and short-term investments $1.63B; r = WACC of 10.1% using this page’s default assumptions (β 1.05, risk-free 5.0%, market premium 5.5%).

Three WACC scenarios

The same calculation under cautious, base and optimistic cost-of-capital assumptions (risk-free rate fixed at the 10-year Treasury yield). Pick one to load it into the sliders below.

Try your own assumptions

V = FCF ÷ (r − g). It starts at the implied growth rate, where the theoretical value equals today’s enterprise value.

Theoretical enterprise value

$35.81B

FCF $931M ÷ (10.1% − 7.5%)

Theoretical ÷ actual enterprise value

1.00x

Below 1x: these assumptions value the business below the market did

How sensitive the answer is

Theoretical ÷ actual enterprise value for each combination of r and g.

g \ r8.1%9.1%10.1%11.1%12.1%
0%0.32x0.29x0.26x0.23x0.21x
2%0.43x0.37x0.32x0.29x0.26x
4%0.63x0.51x0.43x0.37x0.32x
6%1.24x0.84x0.63x0.51x0.43x
8%25.99x2.36x1.24x0.84x0.63x

A simplified model for seeing what the market price assumes, not a forecast or a target price. It treats free cash flow as growing at one constant rate forever; the result swings widely with small changes in r and g, and is undefined when g reaches r. Free cash flow here is operating cash flow minus capex, which is after interest — a full DCF of enterprise value would use cash flow before interest. Market cap uses the latest close (2026-11-04) × shares at fiscal year-end; free cash flow and WACC inputs are from the latest fiscal year.

Earnings qualityFrom SEC dataShow

The same reported profit can mean different things depending on whether it's backed by cash, driven by the core business, or the result of a one-off item. Four checks below.

  • ✓

    Operating CF ÷ net income: averages 1.21x

    Profit is backed by cash coming in.

  • ✓

    Accrual ratio (latest): -3.5%

    A small share of profit rests on accounting estimates.

  • ✓

Who holds the sharesFrom SEC dataShow

How much of the stock large institutional investors report owning on SEC Form 13F, how much the directors and executive officers hold (and how much of the vote they control), and roughly how much is left for individual investors. Shown next to beta so the holder mix can be read alongside how much the stock swings.

Institutions, insiders and everyone else, 13F holdings as of 2026-06-30

“Everyone else” is what remains after shares reported on Form 13F and shares held by directors and executive officers: mostly individual investors, plus non-insider families or foundations and smaller or foreign institutions. The figures have different dates and 13F reports count some shares twice — read it as an approximate split.

  • Directors and executive officers as a group, from the proxy statement’s beneficial-ownership table; includes shares they can acquire within 60 days.

The description and mitigation for each risk are this site’s summary of the 10-K’s "Risk Factors" section. Impact and likelihood are this site’s own assessment, not the company’s — where the company discloses its own likelihood assessment, that is noted in the summary.

Impact is judged from how large the affected business is relative to total revenue/profit, and from the risk’s track record of moving results in the past. Likelihood is judged from the filing’s wording and the current business environment (already occurring, or recurring). See the rating criteria.

    If these customers continue to represent a growing share of our total sales, the loss of, or reduction in purchases by, any one of these key customers could materially and adversely affect our business, financial condition, and results of operations. Increased customer concentration may result in greater pricing pressure, reduced negotiating leverage, and increased exposure to credit risk. As a result, our operating results could therefore fluctuate more significantly from period to period in the future, depending on the purchasing patterns of these large customers.
