Direct Answer
Lumentum's fiscal 2026 filings show a net loss of $6.9 billion. These figures measure financial risk only; the business risks Lumentum itself considers material are listed under Item 1A, Risk Factors, of its Form 10-K, most recently filed August 17, 2026.
What Do Lumentum's Financial Risk Indicators Show?
| Indicator (fiscal 2026) | Lumentum | Peer median (same SIC code) | What it measures |
|---|---|---|---|
| Liabilities to assets | 36% | 50% | How much of the balance sheet is funded by obligations rather than equity. |
| Current ratio | 1.7x | 1.5x | Short-term assets per dollar of obligations due within a year. |
| Interest coverage | 24.1x | 0.7x | Operating income per dollar of interest expense. |
| Long-term debt to operating cash flow | 0.1x | 4.4x | Years of operating cash flow it would take to repay long-term debt. |
| Net debt | -$2.0 billion | n/a | Long-term debt minus cash; negative means more cash than long-term debt. |
The peer median uses 6 other companies in Swoopr's S&P 500 Equal Weight set that share the same SEC SIC code. A reading worse than the peer median is a prompt to read the filing, not a conclusion.
Where Are Lumentum's Official Risk Factors?
The risks Lumentum considers material are disclosed in Item 1A of its Form 10-K, most recently filed August 17, 2026. Read them with three questions in mind: which risks are specific to this company rather than generic, which have changed since the prior year's filing, and which connect to the figures above (a refinancing risk matters more when interest coverage is thin).
Where These Numbers Come From
Every figure on this page is a value Lumentum reported in its own SEC filings, read from the SEC's XBRL data (accession 0001628280-26-057358 for fiscal year 2026). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.
Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
