Lumentum
Lumentum, based in San Jose and spun off from JDSU (now Viavi), makes optical and photonic products — lasers, transceivers and optical components and systems — used in cloud and AI data centers, telecom networks, consumer devices and industrial applications, and calls itself an industry leader by revenue and market share. Fiscal 2026 revenue (year ended June 27, 2026) jumped 83% to $3,014 million (Components $2,006 million, Systems $1,008 million) on AI/ML data center demand, and operating income turned to $525 million. Yet it reported a net loss of $6,935 million because converting and retiring convertible notes produced a $7.76 billion non-cash loss on debt extinguishment. In March 2026 NVIDIA bought $2.0 billion of Lumentum convertible preferred stock. Two customers made up 26.6% and 15.0% of revenue, and BIS and DOJ subpoenaed records about its past business with Huawei.

At a glanceFrom SEC data
Eight headline measures, each placed among the companies covered on this site.
- Revenue growthCAGRSmooths out year-to-year swings into "grew X% a year on average." Makes growth pace comparable across companies of very different sizes.
- 11.6%
- Operating marginOperating marginHow many cents of operating profit are left per dollar of revenue. Reflects pricing power and cost structure.
- 17.4%
- ROIC minus WACCROIC − WACC spreadThe difference between ROIC and WACC. Consistently positive implies value creation; consistently negative implies value destruction.
- -6.9 pts
- Net debt ÷ EBITDAEBITDAOperating income with D&A added back. A rough proxy for cash-generating power that’s less distorted by capital intensity, depreciation method, or financing/tax differences than net income.
- -1.7x
- Cash conversionOperating CF ÷ net income (cash conversion)How much of reported profit shows up as actual cash. 1x or higher means profit is backed by cash.
- —
- Dividend raisesDividend per shareTotal annual dividend paid per share (sum of all declared payments for the year).
- —
- P/E todayP/EShare price ÷ EPS — how many years of current earnings the stock price represents. This site uses the period-end figure as reported in the filing.
- —
- Betaβ (beta)How much a stock moves, on average, for a 1% move in the overall market. Above 1 means more volatile than the market, which raises the return shareholders require. This site computes it from about 2.5 years (roughly 130 weeks) of weekly returns, built from Yahoo Finance daily prices, regressed against an S&P 500 ETF (SPY) as the market proxy, then applies the well-known long-run mean-reversion adjustment (0.67 × β + 0.33) as the WACC default.

Each marker shows where this company sits among the non-financial companies covered on this site, not all listed companies (left = lowest, right = highest). A high position is not automatically good — for net debt ÷ EBITDA, higher means more debt. Details and formulas are in the sections below and in How to read this.

- P/BP/BShare price ÷ book value per share. Below 1x means the market values the company below its accounting net worth. This site uses the closing price nearest the fiscal year-end and highlights sub-1x readings. today
- 12.1x
- EV/EBITDAEV/EBITDAEnterprise value (≈ market cap + interest-bearing debt − cash) as a multiple of EBITDA — roughly, "how many years of EBITDA to buy the whole company." Lower is generally viewed as cheaper, and it’s more comparable than P/E across companies with different debt loads or depreciation policies. This site excludes noncontrolling interests from the EV calculation. today

- FCF yieldFree cash flow (FCF)Operating CF minus capital expenditures — cash generated by the business after funding its own investment, available for dividends, buybacks, acquisitions, or debt paydown. Acquisitions and securities purchases (also in investing CF) are not subtracted, so FCF can be positive in a year when total investing CF exceeds operating CF. today

“Today” uses the latest closing price (2026-11-04, Yahoo Finance daily closing prices) and shares outstanding at the last fiscal year-end. 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 +11.6% a year over 5 years (strong growth)
From $1.74B in FY2021 to $3.01B in FY2026. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.
- ▼
Operating margin declined: 30.2% → 17.4%
How much operating profit is left per $100 of revenue. It moved -12.8 points over 5 years — pricing power, cost control, and product mix all show up here.
- ▲
Equity ratio is 63.5% (a high level of financial stability)
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 4 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 -43.7% over 6 years (latest: -240.0%)
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 (FY2026)
8.3%
formulaoperating income × (1 − tax rate) ÷ invested capital × 100 *invested capital = interest-bearing debt + total equity (average of beginning/ending)
e.g.$525M × (1 − 21%) ÷ $4,995M × 100 = 8.3%
termsOperating income · Effective tax rate · Invested capital · Interest-bearing debt · Total equity
WACC (this site’s estimate)
15.24%
formulacost of equity × equity weight + cost of debt × (1 − tax rate) × debt weight
e.g.Equity weight: $72.38B ÷ ($72.38B + $1.64B) = 97.8%
e.g.Debt weight: $1.64B ÷ ($72.38B + $1.64B) = 2.2%
e.g.WACC: 15.6% × 97.8% + 1.3% × (1 − 21%) × 2.2% = 15.24%
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 12.5%–18.4% and ROIC − WACC runs −10.1 to −4.2 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)
14.7%
Perpetual FCF growth: g = r − FCF ÷ EV = 15.2% − 0.5%
Past FCF growth (FY2021–FY2026)
-14.4%
Compound annual rate, 5 years
Past revenue growth (FY2021–FY2026)
+11.6%
Compound annual rate, 5 years
Inputs (FY2026): free cash flow $300M (operating CF − capex); enterprise value $55.32B = market cap $56.42B (latest close, 2026-11-04) + debt $1.64B − cash and short-term investments $2.74B; r = WACC of 15.2% using this page’s default assumptions (β 1.93, 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
$9.38B
FCF $300M ÷ (15.2% − 12.0%)
Theoretical ÷ actual enterprise value
0.17x
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 \ r | 13.2% | 14.2% | 15.2% | 16.2% | 17.2% |
|---|---|---|---|---|---|
| 0% | 0.04x | 0.04x | 0.04x | 0.03x | 0.03x |
| 2% | 0.05x | 0.04x | 0.04x | 0.04x | 0.04x |
| 4% | 0.06x | 0.05x | 0.05x | 0.04x | 0.04x |
| 6% | 0.08x | 0.07x | 0.06x | 0.05x | 0.05x |
| 8% | 0.10x | 0.09x | 0.08x | 0.07x | 0.06x |
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.

What changed in the risk factorsFrom SEC data
Paragraphs in the latest 10-K's Risk Factors that have little overlap with the year before, and paragraphs that were dropped.
New or substantially reworded (8)
We operate in a market where demand can fluctuate rapidly and we may not be able to predict or quickly respond to trends in the dynamics of our markets and our customers or changes in customer demand, which could negatively impact our gross margins. Although AI is a relatively new demand driver for our products, it is evolving rapidly, and the expected timing and amount of investments related to AI can change significantly. As a result, it may be difficult to accurately forecast such demand and we may incur costs in anticipation of demand that ultimately does not materialize. We manufacture and purchase or commit to supplies based on forecasts of demand from our customers. If we overestimate demand, or if customers cancel or defer orders, change requirements or choose to purchase from our competitors, we may not be able to utilize on-hand inventory or reduce purchase commitments…
Our ability to meet demand is influenced by numerous factors, including changes in product development cycles, ramping technologies, and evolving customer requirements. Read more
Our ability to increase supply of our products is especially dependent on our ability to increase our manufacturing capacity, both at our own facilities and those of our contract manufacturers. Our ability to increase production is subject to a number of uncertainties inherent in all new manufacturing operations, including ongoing compliance with regulatory requirements, procurement and maintenance of construction, environmental and operational licenses and approvals for additional expansion, clean-room capacity, supply chain constraints, hiring, training and retention of qualified employees, implementing highly complex manufacturing processes, and the pace of bringing production equipment and processes online with the…
If demand exceeds our forecasts, we may be unable to scale and increase supply sufficiently to meet such demand, which could result in a loss of revenue, decisions about manufacturing priorities, decisions on supply allocation, damage to customer relationships, legal or other disputes, loss of business and market share to competitors, and loss of future opportunities.
If we are unable to successfully identify, acquire and integrate suitable businesses, our operating results and prospects could be harmed, and any businesses we acquire may not perform as expected or be effectively integrated.
Negotiations for potential acquisitions or other transactions may result in diversion of management’s time and significant out-of-pocket costs. Read more
In addition, we may face risk related to:
We seek to protect our products, technologies, and product roadmaps in part through a combination of patents, trade secrets, know-how, trademarks, copyrights, and ongoing technological innovation. Read more
Our ability to protect our intellectual property is limited, however, because unauthorized use, misappropriation, or infringement of our proprietary rights is difficult, time-consuming, and costly to detect and prevent. The steps we take to protect our intellectual property may be inadequate to prevent third parties from misappropriating our technology or independently developing competing or similar products.
Other companies may be developing technologies that are similar or superior to our own. Read more
In addition, there may be existing patents or other intellectual property rights of which we are unaware that could be relevant to our business. Patent applications are often not published until issued or published after a delay, and as such, we cannot be certain that our products do not infringe pending third-party patent applications. Our pending or future patent applications may not result in issued patents, and any patents that do issue may not provide sufficiently broad protection to prevent others from developing, making, using, or selling products similar to ours, or may be challenged, invalidated, circumvented, or deemed unenforceable.
We do not hold intellectual property rights in every jurisdiction in which we sell or distribute our products. Read more
As a result, competitors may be able to offer identical or similar products in jurisdictions where we lack patent or other intellectual property protection. Further, intellectual property laws and enforcement mechanisms vary by jurisdiction, and certain regions, including Europe, Asia-Pacific and Latin America, may not protect our intellectual property rights to the same extent as the United States.

Unstable market and economic conditions and adverse developments with respect to financial institutions and associated liquidity risk may have serious adverse consequences on our business and financial condition.
Disruptions in access to bank deposits or lending commitments due to bank failures could adversely affect our liquidity, our business and financial condition. Read more
The failure of any bank or financial institution in which we deposit our funds or assets could reduce the amount of cash we have available for our operations or delay our ability to access such funds. Any such failure may increase the possibility of a sustained deterioration of financial market liquidity. The value of our investment portfolio could also be impacted if we hold debt instruments which were issued by any institutions that fail or become illiquid. Our ability to obtain raw materials for our supply chain and collections of cash from sales may be unduly impacted if any of our vendors or customers are affected by illiquidity events.
companies seek alternative solutions, which has reduced the demand for our products from some of our Chinese customers;
We have also faced litigation in connection with acquisitions, some of which continues following the consummation of the acquisition. Read more
Such litigation may be costly and diverts management time and attention.
