Frequently Asked Questions

Why hold Oi S.A. OIBZQ ADR instead of local B3 OIBR3 shares?

Buying directly on Brazil’s B3 exchange means opening a local brokerage account, converting currency and dealing with Brazilian tax paperwork. ADRs remove that friction: they settle in dollars, follow US market hours, and report in formats foreign investors already understand.

The trade-off is that an ADR’s price reflects two moving parts: (1) the underlying share price, quoted in reais on the B3, and (2) the USD/BRL exchange rate. Because of that second part, a rising company can still deliver a flat, or even negative, dollar return if the real weakens against the dollar. The same applies to ETFs: funds such as EWZ, EWZS and FLBR bundle dozens of these companies into a single ticker for instant diversification, but their dollar value still moves with the real.

Where is Oi S.A. listed?

Oi S.A. trades on 2 exchanges. The line quoted on this page is OTC in the United States (OIBZQ, US dollars). It also trades on B3 (São Paulo) in Brazil (OIBR3, Brazilian reais).

On how many exchanges does Oi S.A. trade?

2. OTC — OIBZQ (USD) · B3 (São Paulo) — OIBR3 (BRL). Prices shown on this page are the OTC line, OIBZQ.

What is Oi S.A.'s primary listing?

Oi S.A.'s primary listing is on the B3 in Brazil, where the shares trade as OIBR3 in reais — the company's home market. The OTC line quoted on this page is an ADR over those same shares: it gives you the asset in US dollars, on US market hours, without opening a Brazilian brokerage account or trading in reais.

What is the difference between OIBZQ and OIBR3?

They are the same company and, economically, the same asset. OIBR3 is the original Brazilian share, listed on the B3 and quoted in reais. OIBZQ is an American Depositary Receipt over that share, listed on the OTC and quoted in US dollars — a wrapper whose purpose is to give foreign investors access to the Brazilian asset without opening an account in Brazil. The OIBZQ price therefore tracks two things: OIBR3 in reais, and the USD/BRL exchange rate.

How can I buy Oi S.A. stock in the United States?

Oi S.A. is listed on the OTC under OIBZQ, priced in US dollars. Any US brokerage offering over-the-counter securities can trade it, with no foreign-account paperwork and no currency conversion.
