I recently organized a comparison chart of the annual financial report release schedules for Taiwanese stocks and U.S. stocks, and I found that many investors are actually not very clear about these dates. However, mastering the timing of financial report releases is really key to making trading decisions.

Let's start with Taiwan stocks. Taiwan's financial reporting regulations are quite strict; all listed companies must complete their filings within the statutory deadlines, with little room for flexibility. I summarized the key dates for 2026 as follows: annual reports must be announced before March 31 (financial holding companies have extended this to April 30), Q1 quarterly reports are due by May 15, Q2 by August 14, and Q3 by November 14. There’s also a Taiwan stock market-specific rule — each company must announce last month’s revenue before the 10th of each month, which is especially useful for gauging trends before quarterly reports.

Recently, I noticed an interesting phenomenon: mega-large companies like TSMC and MediaTek are required to announce their annual reports earlier starting in 2026 — by March 15, instead of the usual deadline. This means that the annual financial reports of big companies will be released earlier, allowing investors to get information ahead of others.

The logic for U.S. stocks is different. U.S. annual reports are filed as Form 10-K, quarterly reports as Form 10-Q, with deadlines depending on the company's size. Large accelerated filers must submit within 60 days after the fiscal year-end (for 2025, the deadline is March 2), mid-sized companies within 75 days, and small companies within 90 days. Quarterly reports are similar — large companies have 40 days, small companies 45 days.

But here’s a key point — companies usually release their financial reports well before they officially file with the SEC. The U.S. earnings season typically kicks off about 15 days after the quarter ends, usually starting with big bank stocks, then moving into the “super earnings week” for tech giants. For example, TSMC ADRs are usually announced in mid-April, while tech giants like Tesla, Microsoft, and Apple tend to release their reports from late April to early May.

Regarding how I check these dates, my approach is this: for Taiwan stocks, I use the Public Information Observation Station (MOPS), which is the most authoritative source — all listed companies’ financial info must be published there. For U.S. stocks, I go directly to the SEC’s EDGAR database to look up Form 10-K and 10-Q filings. But if I want to get an overview of multiple companies’ report release schedules and earnings call timelines at once, financial calendar websites like Yahoo Finance, Nasdaq’s official site, and SeekingAlpha are also very helpful, saving me the trouble of checking each one individually.

Honestly, mastering the timing of financial report releases is very important for both short-term trading and long-term investing. Stock prices tend to fluctuate significantly around earnings season, and knowing the schedule in advance helps you plan your trading strategies better.
