"Avacta shares trade in the US primarily on the over-the-counter (OTC) markets under the ticker AVCTF.

Key Details on OTC Trading for AVCTFMarket Tier: It trades on the OTC Pink Limited market (sometimes referred to as OTCPK or Pink Sheets).
otcmarkets.com
Pink Limited is the lowest transparency tier on OTC Markets. It is intended for companies with limited or no issuer involvement in providing ongoing disclosures.
Avacta does not file regular financial reports or other disclosures directly with OTC Markets (it reports via the UK's AIM rules and RNS instead).

Trading Characteristics:Liquidity: Very low. Average daily volume is often in the low thousands of shares (e.g., around 2,500 shares), with some days seeing only a few hundred or even fewer.

Spreads: Bid-ask spreads can be wide due to thin trading, which increases transaction costs and execution risk for US investors.
Price Quotation: Prices are in USD and reflect the underlying GBP share price on AIM, adjusted for the exchange rate. The OTC price generally tracks the primary LSE AIM listing (AVCT.L), but with a lag and potential premium/discount due to currency and liquidity differences.

Volatility: Can be high, partly due to low volume.
Accessibility:Available through many US brokerage platforms that support OTC/Pink Sheet stocks (e.g., via OTC Markets or major brokers like Fidelity, Schwab, or Interactive Brokers).
US investors can buy/sell during US market hours, but best execution often aligns with London trading hours for better liquidity on the primary market.
No direct listing on NASDAQ, NYSE, or other major US exchanges.
Risks and Considerations:Limited Information: Investors rely primarily on Avacta's UK disclosures rather than US-specific SEC filings.

Higher risk profile due to low liquidity, potential for price manipulation in thin markets, and the general risks of AIM-listed biotechs (clinical stage, no profits, dilution risk, etc.).
Currency risk (GBP/USD fluctuations affect the effective return).
Some brokers may have restrictions, higher fees, or require "OTC stock" approval for trading Pink Sheets."
