The upcoming earnings season is almost here, and many people have been asking me when the first-quarter earnings reports will be released. So I’ve gone ahead and organized the earnings-report schedules for Taiwan stocks and U.S. stocks to share with everyone.

First, for Taiwan stocks, our rules are actually quite strict. The statutory deadline for the first-quarter 2026 earnings report is May 15, but in practice, many large companies hold their earnings calls earlier. Usually, they start releasing results gradually from mid-to-late April through mid-May. For mega-cap companies like TSMC and MediaTek, they often announce as early as possible, and you can also expect more noticeable stock price volatility.

The pace in the U.S. is a bit different. The filing deadline for first-quarter earnings depends on the size of the company. Large accelerated filers must submit within 40 days after the quarter ends—around May 11, 2026. However, the real earnings calls typically begin earlier. Roughly 15 days after the quarter ends, some companies start publishing their earnings reports. Last year, I noticed that bank stocks usually go first, followed by the “super earnings week” for tech giants. Companies like Microsoft, Apple, and Meta release their results intensively from late April to early May.

If you want to look up the specific earnings-release dates, for Taiwan stocks you can simply use the Public Information Observation Station (MOPS). This is the most authoritative source, and all listed companies’ earnings report data are available there. For U.S. stocks, you can use the SEC’s EDGAR database, or go directly to each company’s investor relations website to check—typically, they post a release time in advance. Many brokerage apps also have an organized earnings calendar, so you can just scroll to see which companies are scheduled to report recently.

To be honest, knowing the timing of when the first-quarter earnings are released is quite important for trading. During earnings season, stock prices tend to fluctuate a lot, and knowing the timeline in advance can help you plan your entry and exit rhythm more effectively. Especially for those large companies that hold earnings calls early, there are often clear stock price reactions even before the reports are officially released—this is also why many people treat the earnings calendar as an essential tool.
