Frequently asked questions

Is DIOD growing its revenue and profit?

Over the past 5 years, Diodes Inc /Del/'s revenue has grown 3.8% per year, and net income declined 7.6% per year. These are computed facts, not advice.

How much debt does DIOD have?

What is DIOD's profit margin?

In FY2025, gross margin was 31.2%, operating margin 2.4%, and net margin 4.5%.

What is DIOD's P/E ratio?

Diodes Inc /Del/'s P/E (TTM) is 45.09 as of the 2026-11-03 close — market cap ÷ net income over the trailing twelve months where four consecutive quarters are reported, otherwise the latest fiscal year, the same figure as on the DIOD stock page. The valuation chart above sets each month-end's price against the latest annual net income instead, so its latest point (about 58.7× as of Nov '26) can differ. These are computed facts, not advice.

Where does this data come from?

All figures are extracted from the company’s SEC EDGAR/XBRL filings — 10-K annual reports and 10-Q quarterly reports (use the Annual / Quarterly toggle). Quarterly figures are derived from the as-filed statements (year-to-date amounts are differenced into discrete quarters). Growth rates and ratios are computed by tradmap; nothing here is investment advice.
