Background — TSM and its listings
Taiwan Semiconductor Manufacturing Company (TSMC) is the world’s largest pure-play semiconductor foundry. It manufactures chips for many global fabless semiconductor companies and integrated device manufacturers. TSMC’s primary listing is on the Taiwan Stock Exchange under its local share class. For international investors, American Depositary Receipts (ADRs) have historically represented TSMC shares on the NYSE under the ticker TSM.
Important listing and ADR mechanics to know:
- Domestic shares: TSMC’s ordinary shares trade locally in Taiwan and are subject to Taiwan Stock Exchange rules and corporate actions declared in Taiwan.
- ADRs on NYSE: ADRs are certificates issued by a depositary bank representing one or more local shares. The ADR-to-local-share ratio can change over time and determines how splits and dividends are passed to ADR holders.
Because ADRs are intermediated by depositary banks, a split declared by TSMC in Taiwan is converted into an ADR-level adjustment by the depositary. That conversion — and historical ADR-to-local-share ratio — affects how ADR holders saw the split reflected in their holdings and account statements.
Chronological stock split history
A concise chronological list of reported split events (common reporting sources list 10 splits). Exact ratio formatting and presentation can vary by data provider; this list follows commonly aggregated historical records.
- Aug 26, 1998 — 145:100 (≈1.45:1)
- Aug 16, 1999 — 123:100 (≈1.23:1)
- May 15, 2000 — 128:100 (≈1.28:1)
- Jun 26, 2001 — 140:100 (≈1.40:1)
- Jun 19, 2002 — 11:10 (≈1.10:1)
- Jul 07, 2003 — 108:100 (≈1.08:1)
- Jun 14, 2004 — 114:100 (≈1.14:1)
- Jun 13, 2005 — 105:100 (≈1.05:1)
- Jun 20, 2006 — 103:100 (≈1.03:1)
- Jul 15, 2009 — 1005:1000 (≈1.005:1; some sources report 201:200)
Each of the above entries reflects the common split ratios reported by market-data aggregators. Small fractional splits (like 1005:1000 or 201:200) are sometimes reported in multiple equivalent formats — rounding and presentation differ across sources.
Because of ADR conventions and the way depositaries re-denominate ADRs, many historical sources summarize the cumulative effect as local ADR holdings bought in the late 1990s converting into approximately 4.7x the original ADR count after the full sequence. This cumulative figure is a commonly cited way to convey the combined impact of multiple small and mid-size splits.
Throughout this article you will see the question has tsm stock ever split repeated in context to ensure clarity and search relevance.
Why companies split stock (context for TSM’s splits)
Stock splits are corporate actions where a company increases the number of shares outstanding while proportionally reducing the per-share price so total market capitalization remains unchanged. Typical reasons companies (including TSMC) choose to split shares include:
- Increase liquidity: Lower per-share prices can attract a broader base of retail traders and increase trading activity.
- Improve accessibility: A lower nominal share price may make a stock more accessible to smaller investors and employees who receive equity compensation.
- Facilitate compensation and corporate programs: Splits can make share-based compensation grants or option programs easier to manage and price.
Important to emphasize: splits are cosmetic with respect to fundamentals. They do not alter a company’s revenue, profit, or market cap directly, though market psychology and liquidity effects sometimes lead to short-term price moves.
The recurring question "has tsm stock ever split" captures the practical curiosity many investors have when they see substantial historical price appreciation: yes, several splits occurred historically, mainly from 1998–2009.
ADRs vs. Taiwan-listed ordinary shares — practical implications
The mechanics of applying a split to ADRs differ from applying a split to local domestic shares. Key points:
- ADR ratio: An ADR may represent multiple local shares (or a fraction of a local share). When a domestic split occurs, the depositary bank responsible for the ADR adjusts the ADR ratio or issues additional ADRs to maintain equivalent ownership.
- Notice and timing: ADR adjustments commonly follow domestic corporate action announcements. ADR holders should rely on depositary bank notices (and NYSE filings where applicable) to see how an action is processed at the ADR level.
- Fractional ADRs: In some situations, depositary banks may pay cash in lieu for fractional ADR adjustments or update the ADR ratio.
If you are asking "has tsm stock ever split" in order to understand how your ADR position changed, check the depositary bank’s notices and your broker statements. For domestic shareholders, consult the Taiwan Stock Exchange filings or TSMC investor relations announcements.
Market impact and historical performance
Direct effects of splits
- Market capitalization: Unchanged by splits. A 2-for-1 split doubles share count and halves price per share; total market value remains the same immediately after the split.
- Liquidity and participation: Splits often increase liquidity and can raise retail investor participation, which may influence intraday and short-term price dynamics.
Historical performance context for TSM
- The question "has tsm stock ever split" is often asked by investors who notice large historical price movements. Splits in the 1998–2009 window were part of the broader corporate practice to keep per-share prices within certain ranges and to facilitate marketability.
- Since the last widely reported split in July 2009, TSM shares (both local shares and ADRs) have appreciated substantially over multi-year horizons due to fundamental demand for advanced process nodes, capacity expansions, and increasing semiconductor content across industries.
While splits themselves did not change TSMC’s fundamentals, the company’s growth in revenue, margins, customer demand, and capital investments have been the primary drivers of long-run share performance.
Management and future splits
- Management announcements: As of the latest aggregated reports (see references), management had not publicly announced further splits after 2009. Investors should monitor official investor relations channels and depositary notices in case of future corporate actions.
Questions about "has tsm stock ever split" are valid for understanding both historical holdings and how past corporate actions affect cost basis and share counts for long-term holders.
How to verify and find official split information
When checking an historical split record or confirming how an ADR was adjusted, rely on official sources and reputable market-data aggregators:
- TSMC investor relations (official press releases and corporate action notices) — primary source for domestic splits and board resolutions.
- Taiwan Stock Exchange filings — official domestic registry of corporate actions and record dates.
- ADR depositary notices and NYSE filings — for ADR-level mechanics and how ADR ratios were adjusted.
- Market-data aggregators and split-history pages (examples frequently used by researchers): Macrotrends, SplitHistory, Investing.com, and other split-history summaries. These sources aggregate historical corporate actions and are useful for cross-checking.
As of 2026-01-23, according to commonly referenced split-history aggregators and TSMC communications, the split dates and ratios listed in this article reflect the most commonly reported sequence used by market-data services. For legal or tax questions, always rely on official filings and statements from TSMC or the depositary bank.
Practical examples — how splits affected share counts
Example: if an investor purchased 100 TSM ADRs in 1997 and held through the series of splits recorded between 1998 and 2009, the cumulative effect of those splits (as reported by many sources) could increase ADR count by roughly 4.7x. That means those 100 ADRs could have become approximately 470 ADRs after the sequence of splits depending on the precise ADR conversion rules at each event.
Note: this example is illustrative and meant to explain how multiple successive splits compound. Exact historical outcomes depend on the ADR ratio in effect at each date and any actions taken by the depositary bank (including cash-in-lieu for fractional ADRs).
Taxes, record dates, and cost basis considerations
- Record and pay attention to dates: Each split has a record date, ex-date, and distribution mechanics that brokers and depositaries use to update share counts. Keeping broker statements and depositary notices is essential for tracking cost basis and tax records.
- Cost basis: While a split does not create a taxable event in many jurisdictions, it changes the per-share cost basis. Splits proportionally adjust cost basis per share; investors should maintain records showing pre-split holdings and broker confirmations.
- Corporate action confirmations: If you hold ADRs, the depositary bank usually sends confirmations and instructions — save these for tax reporting and historical accuracy.
If you need help confirming historical cost basis or handling tax reporting around past splits, consult a tax professional and use the official corporate action notices as primary documentation.
Market-data discrepancies and reporting conventions
Different data vendors sometimes show small discrepancies when reporting split ratios and cumulative effects. Reasons include:
- Rounding and representation: A split of 201:200 can be presented as 1005:1000 in some records, or as a decimal multiplier like 1.005:1. These are mathematically equivalent when interpreted correctly.
- ADR ratio adjustments: Because ADRs may have represented multiple local shares at different times, vendors may represent ADR-level changes differently from local-share reporting.
- Aggregation and historical corrections: Vendors occasionally revise historical corporate-action tables when new documentation surfaces.
Because of these factors, if precise legal detail or audit-level accuracy is required, consult the original press release or depositary bank notice for each split event.
