XBRL tags used: revenue = RevenueFromContractWithCustomerExcludingAssessedTax; netIncome = NetIncomeLoss; assets = Assets; eps = EarningsPerShareDiluted; cash = CashAndCashEquivalentsAtCarryingValue. EPS is shown as originally reported for each year and may not be adjusted for later stock splits. A dash means the company did not report that item in a form we could match.

How to read these numbers

Revenue is the money a company brings in from selling its products and services; net income is what is left after all expenses, interest and taxes. Diluted EPS spreads net income across every share that could exist if options and convertible securities were exercised. Total assets and cash are balance-sheet figures measured on the last day of the fiscal year.

Insider filing activity

31 Form 4 filings appear in A10 Networks, Inc.’s EDGAR record between Oct 28, 2025 and our last refresh. Most are reports by the company’s own directors, officers and 10% owners, but EDGAR also lists a Form 4 under a company when the company itself is the insider — for example, when it owns more than 10% of another public company. Foreign private issuers’ own insiders generally do not file Form 4. A high count is not by itself a signal: many Form 4s report routine stock awards, tax withholding or sales under pre-arranged Rule 10b5-1 plans. Open each filing to see the transaction code, share count and price. What a Form 4 shows.
