ADRs Explained: How to Buy Foreign Stocks on US Exchanges

Published: March 15, 2026 | Category: International Investing | Reading time: 6 min

You want exposure to a Japanese automaker, a Swiss pharmaceutical giant, or a Brazilian mining company. But your brokerage is set up for US markets, you're not equipped to deal with foreign exchange accounts, and trading on the Tokyo Stock Exchange or São Paulo's B3 sounds like more complexity than you're looking for. There's a solution, and it's been around for nearly a century: American Depositary Receipts, better known as ADRs. Understanding how they work — and their limits — can open up a significant slice of global investing to anyone with a standard US brokerage account.

What Is an ADR?

An American Depositary Receipt is a negotiable certificate issued by a US depositary bank that represents ownership of shares in a foreign company. Rather than buying shares of Toyota Motor directly on the Tokyo Stock Exchange and dealing with yen-denominated transactions, a US investor can buy ADR shares of Toyota that trade on US exchanges in US dollars, just like any domestic stock.

Here's the basic mechanic: a depositary bank — typically a major institution like JPMorgan, Citibank, or Bank of New York Mellon — holds the underlying foreign shares in custody in the company's home market. It then issues ADRs in the US that represent a specific number of those underlying shares (the "ratio" can vary — one ADR might equal one share, or five, or one-half, depending on how the depositary structures it). US investors buy and sell ADR shares through their normal brokerage accounts. Currency conversion is handled by the depositary bank, not by the investor directly.

This structure elegantly solves several problems: it handles currency conversion, eliminates the need for foreign brokerage accounts, brings the investment under US securities regulation, and makes foreign equities accessible to retail investors.

Sponsored vs. Unsponsored ADRs

Not all ADRs are created equal, and the distinction between sponsored and unsponsored matters.

Sponsored ADRs are established with the cooperation and participation of the foreign company itself. The company enters into an agreement with the depositary bank, files with the SEC, and provides financial reporting to US investors. The foreign company has an active interest in maintaining the ADR program and keeping US investors informed.

Unsponsored ADRs are created by one or more depositary banks without the foreign company's formal involvement. The company doesn't have a direct relationship with the depositary bank and doesn't file separately with the SEC for the ADR. These typically trade over-the-counter, may have less reliable or timely information flow, and can have higher fees embedded in the structure. For most investors, sponsored ADRs are the preferable option.

The Three Levels of Sponsored ADRs

Sponsored ADRs come in three levels, each with different regulatory requirements and trading venues — and understanding the differences helps you assess what you're actually holding.

Level I ADRs are the most basic. They trade on the OTC (over-the-counter) markets rather than on major US exchanges. The foreign company files a minimum amount of documentation with the SEC, and it does not need to reconcile its financials to US GAAP (Generally Accepted Accounting Principles). Level I ADRs give a company a presence in US markets with limited regulatory burden — but they also give investors less transparency. They cannot be used by the foreign company to raise new capital in the US.

Level II ADRs are listed on major US exchanges — the NYSE or NASDAQ. This requires the foreign company to register with the SEC and provide more substantial disclosures, including annual reports on Form 20-F. However, Level II ADRs still do not allow the company to raise new capital through the US market. They simply give the company a US listing for its existing shares.

Level III ADRs represent the full commitment. These are listed on major US exchanges and allow the foreign company to raise capital through US public offerings. Level III programs require the most robust SEC reporting, including full reconciliation to US GAAP or IFRS. When you see a foreign company doing a US IPO or a secondary offering through its ADR, that's a Level III structure. Companies using Level III ADRs have made the most significant commitment to US investors in terms of transparency and disclosure.

Currency Conversion: Who Does the Work?

One of the key appeals of ADRs is that the depositary bank handles currency conversion behind the scenes. When a French company pays a dividend in euros, the depositary bank converts those euros to US dollars and distributes the equivalent amount to ADR holders — minus a small fee, typically a few cents per share.

For dividend-oriented value investors, this is worth understanding clearly. Your dividend payment will vary in US dollar terms not just based on the company's payout, but based on the exchange rate at the time of conversion. A strong US dollar reduces what you receive; a weak dollar increases it. The underlying dividend in local currency terms may be perfectly steady while your ADR dividend in dollars fluctuates.

This currency effect applies to capital appreciation as well. If you buy a German company's ADR at $50 and it rises 10% in euro terms, but the euro weakens 10% against the dollar during your holding period, your ADR might be roughly flat in dollar terms. The local return and the currency return combine to produce your total dollar return. More on currency dynamics specifically is covered in our dedicated post on currency risk.

Withholding Tax on ADR Dividends

This is an area that catches many investors off guard. Most countries impose a withholding tax on dividends paid to foreign investors, including ADR holders. The rate varies by country and depends on any tax treaty between that country and the US.

For example, Germany and Switzerland generally withhold taxes on dividends before they're paid to foreign investors. Some of this can be reclaimed through US tax procedures, or may be creditable against your US taxes via the foreign tax credit. But the process can be complicated, and the effective after-tax dividend you receive may differ meaningfully from the stated yield.

Before buying individual ADRs for income, understand the applicable withholding tax rate in the company's home country. This is especially relevant for high-yield ADRs from countries without favorable tax treaties with the US.

ADRs as a Value Investing Tool

For the value investor, ADRs are genuinely useful. They expand your investable universe considerably — allowing you to buy individual foreign companies based on your fundamental analysis, rather than committing to a broad ETF that includes companies you wouldn't otherwise own.

The same criteria apply: earnings quality, return on equity, dividend sustainability, book value, competitive position, and valuation relative to intrinsic value. The additional layer of analysis is understanding country-specific risks — regulatory environment, political stability, currency trends, accounting standards — that affect the foreign company's prospects.

Actionable Takeaways

• ADRs let you buy foreign companies through your standard US brokerage — no foreign exchange account needed; currency conversion is handled by the depositary bank.
• Choose sponsored ADRs over unsponsored — they provide better disclosure, stronger SEC oversight, and a direct relationship with the foreign company.
• Know your ADR level: Level I trades OTC with minimal disclosure; Level II is exchange-listed; Level III is exchange-listed and allows US capital raises with the most rigorous reporting.
• Factor in withholding taxes before buying for income — the after-tax dividend yield on many foreign ADRs is lower than the stated yield due to home-country tax withholding.
• Apply your full value framework — ADRs are not a shortcut around fundamental analysis; the valuation and quality work still needs to be done.
