Transition from OTCQB to Unsponsored OTC Quotation

US branch share register to close during December 2026

ADELAIDE, AU / ACCESS Newswire / July 30, 2026 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or Company) advises that as at close of business on Friday, 31 July 2026 (EST) its shares will no longer be quoted on the OTCQB Venture Market.

Barton's shares will continue trading on its primary Australian Securities Exchange (ASX) listing under the ticker BGD, and BGDFF shares will transition to OTC Markets quotation on Monday, 3 August 2026 (EST). Owners of BGDFF shares will remain the beneficial owners of underlying Barton shares following this transition.

The decision to discontinue Barton's issuer-sponsored OTCQB listing will have no impact on Barton's underlying business operations, strategic priorities, or ability to execute on its production or development plans.

Background

Barton shares commenced trading on the OTCQB Venture Market under the ticker BGDFF during August 2023.¹ The Company also secured approval for registration of BGDFF with the Depository Trust & Clearing Corporation (DTCC) and opened a US branch share register (US Share Register) during November 2023, maintained by Barton's US Transfer Agent Dynamic Stock Transfer Inc. (Dynamic), enabling real time trading and settlement of BGDFF in the United States by a wide range of full service brokers, and migration of BGD shares to the US.²

The Company's decision to cease OTCQB Venture Market sponsorship reflects a low perceived value relative to its cost and the low trading volumes by shareholders on that Market. In particular, it is Barton's understanding that US securities markets' shift to T + 1 settlement during 2024 has resulted in challenges with timely physical settlement of securities between Australian and US markets, resulting in reduced clearing house participation.

Transition to OTC quotation

Having regard to these factors, the Company is of the view that maintaining OTCQB sponsorship is not of sufficient value to Barton shareholders. Its OTCQB listing will transition to an unsponsored (Pink Limited Market) quotation on the OTC Markets Group on Monday, 3 August 2026 (EST) under the ticker BGDFF.

Closure of US Share Register

Barton also advises that it plans to close its US Share Register on or around 1 December 2026. This will result in the repositioning of all shares currently held on the US Share Register (including those held by broker-dealers within the US central securities depository, Depository Trust Company (DTC)) to Barton's Australian principal share register (Australian Share Register) maintained by Barton's Australian Share Registrar, Computershare Investor Services Pty Limited (Computershare).

The shares will be registered on the Australian Share Register directly in the name of the registered shareholder or DTC participant (i.e. US broker-dealer, holding the shares on behalf of beneficial owners), as applicable, on the issuer sponsored subregister (i.e. in uncertificated form). An issuer sponsored holding statement will be despatched by post, by Computershare, to the shareholder's registered address. The holding statement will confirm the shareholding and Securityholder Reference Number (SRN). The SRN should be regarded as confidential and holders should avoid disclosing it to anyone other than Computershare, or their broker.

The statement will be evidence of the shareholding on the Australian Share Register and will be required to support any future transfer or sale of Barton shares on the ASX.

Following the repositioning of all shares held on the US Share Register to the Australian Share Register, all trading of Barton shares will take place on the ASX with settlement via the Clearing House Electronic Subregister System (CHESS), which is the ASX's system for trade settlement, transfer of legal ownership, and electronic record-keeping for listed equities.

Barton anticipates that this repositioning of Barton shares from the US Share Register to the Australian Share Register will provide improved liquidity to current US holders of Barton shares, and anticipates no practical impact to trading in Barton shares. Only approximately 509,000 Barton shares are presently held on its US Share Register, being less than 0.2% of all issued and outstanding Barton shares.³

Further information for BGDFF investors

If an investor owns BGDFF shares traded on the OTCQB, following the transition to OTC quotation nothing has changed with the underlying shares themselves. Investors remain the beneficial owners of the shares and may trade them through the broker-dealer of their choice.

Barton shares will also remain accessible via the OTC Market Group (Pink Limited Market), both before and following the repositioning of Barton shares from the US Share Registry to the Australian Share Registry. However, the Company cautions investors that trading in unsponsored OTC Markets Group securities may be subject to reduced liquidity and visibility following the transition (compared to OTCQB sponsored quotation, or trading and settlement directly on the ASX).

If an investor's broker-dealer does not provide services for OTC Markets Group securities, the investor may need to identify a registered broker-dealer that provides these services. Similarly, following the closure of Barton's US Share Register, an investor's broker-dealer may not provide services for shares thereafter to be held on the Australian Share Register and traded on the ASX, in which case the investor may need to identify a registered broker-dealer that provides these services.

Shareholders impacted by the transition are encouraged to consult their financial advisors or broker-dealers for additional information regarding trading mechanics following the transition.

BGDFF holders may request their broker-dealer to contact Barton's US Transfer Agent, Dynamic, to reposition their securities to the Australian Share Register in advance of the closure of the US Share Register (anticipated to occur during December 2026) in order to gain sooner access to ASX trading and CHESS settlement. Dynamic's contact details are:

• Email: [email protected]

• Phone: +1 213 667 0197

Commenting on the transition to OTC, Barton Managing Director Alexander Scanlon said:

"Despite the considerable demand for Barton Gold shares in the North American market, the issuer-sponsored OTCQB market has been unable to provide a suitably functional platform for our investors to access liquidity in Barton shares.

"This appears to be largely related to a shift to T+1 settlement in North American markets which occurred only a few months after the opening of our US branch share register. This was an unfortunate adjustment which we understand has affected several Australian-listed, DTC registered securities, some of whom have taken similar decisions to Barton.

"Less than 0.2% of Barton's outstanding shares are affected by this issue, however we anticipate that moving all shares held on our US share register back to our Australian share register will provide improved liquidity for our US investors."
