PORTOFINO ANNOUNCES CHANGE OF NAME TO LATAM LITHIUM CORP. AND COMPLETION OF SHARE CONSOLIDATION

Portofino Resources Inc. has changed its name to LatAm Lithium Corp. and has completed the previously announced consolidation of its common shares.

Further to the news release dated April 7, 2026, the company has received final acceptance from the TSX Venture Exchange for both the consolidation and the name change. Additionally, the name change and consolidation were previously approved by the company's board of directors pursuant to the company's articles of incorporation.

The consolidation has been completed on the basis of 10 preconsolidation common shares for one postconsolidation common share. No fractional shares will be issued. Fractional entitlements will be rounded down to the nearest whole share.

Effective at the opening of trading on April 30, 2026, the company's postconsolidation common shares will commence trading on the TSX-V under the new name LatAm Lithium Corp. and the new trading symbol LALI.

A new Cusip number 517953105 and ISIN CA5179531051 have been assigned to the company's common shares.

Existing share certificates representing preconsolidation shares remain valid but now represent the postconsolidation number of shares according to the consolidation ratio. Registered shareholders will receive a letter of transmittal with instructions on exchanging certificates if desired (or as required by the transfer agent). Beneficial shareholders holding through brokers should have their positions automatically adjusted.

The company's outstanding warrants and options have been adjusted in accordance with their terms to reflect the consolidation.

The name change and consolidation are intended to better reflect the company's current business focus on low-cost, high-grade lithium brine mineral exploration and development in Argentina.

The company's website has been updated.
