American Depositary Receipt (ADR) Information

Our U.S. ticker symbols are TGSNF and TGSGY. These symbols represent TGS in the U.S. market, specifically on the OTCQX tier. Investors in the U.S. can use these tickers to track TGS’s stock performance, execute trades at their brokerage firm, and view detailed financial information.

• TGSNF is foreign ordinary shares that trade in the U.S. under the company's U.S. ticker, without the intermediary of a depositary bank. They are traded in U.S. dollars, just like ADRs, but represent the actual foreign shares rather than a derivative.
• TGSGY refers to our ADR (American Depositary Receipts) program, which is securities issued by U.S. depositary banks that represent shares of a foreign company. ADRs trade in U.S. dollars and allow U.S. investors to buy shares of non-U.S. companies without needing to deal with foreign currency exchanges.

TGS is listed on the OTCQX, which is the top tier of the OTC Markets Group, designed for established and investor-focused companies.

Trading on OTCQX is conducted through a broker-dealer network. Investors buy and sell securities through a licensed U.S. broker or financial institution, just like they would with any other U.S.-listed stock.

U.S. investors can buy shares through U.S. brokerages. They simply need to search for our U.S. ticker symbol TGSNF for the ordinary share or TGSGY for the ADR to trade our stock.

Our company trades on the OTCQX tier, the premier tier of the U.S. OTC markets. This tier is for companies that meet high financial standards, follow best practice corporate governance, and have demonstrated a commitment to investor transparency.

By joining OTCQX, TGS demonstrates a commitment to providing transparent information and maintaining high standards of corporate governance. Investors can feel more confident in the integrity of the company, as it meets the requirements to be traded on the top tier of the OTC Markets. This makes the stock more attractive to U.S. institutional and retail investors, increasing potential liquidity and visibility in the U.S. market. OTCQX grants Blue Sky Compliance clearance in 40+ U.S. states, critical for the legal sale of our securities, distribution of research, and inclusion in various portfolios.

OTCQX offers enhanced visibility through better market access for U.S. investors, increased exposure on trading platforms, and potential inclusion in financial data systems and media outlets that focus on U.S.-listed companies. By adhering to OTCQX standards, TGS gains a reputation as a reliable and transparent business.

Yes, U.S. investors can access TGS’s financial information, disclosures, and news updates on the OTC Markets website under our U.S. ticker TGSNF and TGSGY. This ensures that investors have access to the same transparent and timely information as they would with any U.S.-listed company.

While OTCQX provides a premier market for established companies, it differs from traditional U.S. exchanges like NYSE or NASDAQ. Companies trading on OTCQX are not subject to the same registration requirements as those on major exchanges but must meet high financial standards, provide ongoing disclosures, and follow best practice corporate governance. The SEC Rule 12g3-2(b) exempts non-US companies from registering securities under the Exchange Act, allowing them to trade in the US on OTC Markets if they provide their home country disclosures to the public. This exemption lowers regulatory costs and simplifies access to US investors, enabling companies to broaden their investor base without the full burden of SEC reporting.
