Who owns Silicon Motion Technology?

Silicon Motion Technology trades in the U.S. through ADRs, certificates that represent shares of a non-U.S. company. Form 13F counts ADRs while the company reports ordinary shares, so we do not compute percentages. Holders reporting more than 5% of the ordinary shares to the SEC (Schedules 13D/13G): FMR, 6.7% (13G/A filed Aug 6, 2026). As of Jun 30, 2026, the largest ADR holders reported on Form 13F were FMR (2.3 million ADRs), Acadian Asset Management (1.3 million ADRs) and Invesco (1.1 million ADRs).

Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M.

From the statements the company filed with the SEC (10-K). The change compares average diluted shares of each fiscal year, on today's basis: negative = it bought back more than it issued; positive = dilution. “No data” = the company does not report that item under a tag we can read; it does not mean zero.

Earnings quality and debt

Operating cash flow ÷ net income (12 months)

Interest coverage (operating income ÷ interest)
no data
Debt due within 12 months
no data

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.

This company filed no 8-K forms in the last year. Foreign companies listed in the US (ADRs) report material events on forms 6-K and 20-F, and ETFs and funds do not file 8-Ks. If it is a foreign company listed in the US through ADRs (American Depositary Receipts), what trades are bank-issued certificates that represent shares from its home market.
