Funds own 5.0% of the company, counted in US-listed ADS (Q2 2026)Fund managers with more than $100 million in US-listed stocks file a 13F each quarter. It lists their long stock positions only (shorts, options and bonds are left out) and can arrive up to 45 days after the quarter ends, so this is a snapshot of the quarter end. We add up the shares every fund reports in this class and divide by the shares outstanding. The total can pass 100%: the same shares are often reported by more than one manager (an adviser and the fund it runs), lent shares can be reported twice, and the share count can be out of date after buybacks. We divided 143.84M reported ADSs by 2.86B ADSs, from a count we checked by hand as of Dec 31, 2025. An ADS stands for a fixed number of the company’s ordinary shares, so the company’s shares are converted to ADSs. 13F covers only ADSs listed in the US. Shares held at home and by funds abroad are not in it, so this figure is lower than global institutional ownership figures.
207 funds hold the ADSs.

Each point is a quarter-end, from Q2 2013 to Q3 2026. A fund's 13F lists its long positions in US-listed securities as of the last day of the quarter and arrives up to 45 days later, so each point shows holdings at quarter-end, not on the day they were reported.
Common shares only; options and bonds are left out. When a fund amends a report, the amended version is the one counted.
The history follows the company's current CUSIP number (204409601). If the company's shares were ever re-issued under a different CUSIP, the quarters before the change are not part of this series, so the first point (Q2 2013) can be later than the stock's first appearance in 13F reports.
Share counts are adjusted for stock splits (1.31-for-1 on Jan 13, 2014, 1.04-for-1 on Aug 13, 2020, 1.3-for-1 on May 2, 2022, 1.3-for-1 on May 19, 2022, 1.3-for-1 on May 24, 2024): reports from before a split are multiplied by its ratio, so every quarter is on the share count of Q3 2026.
A quarter appears once our daily update has built its summary. If a summary cannot be built, older reports are kept and the chart shows the quarters it has until the next update repairs it.
