Lithium Chile and China Union Holdings Ltd. Sign an Amended and Restated Share Purchase Agreement
Deal Amendment Clarifies Ownership Structure Ahead of Shareholder Vote

Executive Summary
- Lithium Chile Inc. signed an amended and restated share purchase agreement with China Union Holdings Ltd. on May 7, 2026.
- The amendment clarifies beneficial ownership of Argentum Lithium S.A. shares held by Mr. Cochrane, confirming they are held in trust for the Company.
- Contractual amendments include revised definitions regarding government interventions and updated indemnities covering post-closing government actions for 60 months.
- Maximum liability for breaches of representations or warranties remains unchanged despite indemnity modifications.
- Transaction remains subject to TSX Venture Exchange approval and shareholder vote scheduled for May 15, 2026.
- Target closing date is June 30, 2026, pending Chinese outbound direct investment (ODI) approval and acquisition of additional interest from joint venture partner LitiAr S.A.
Material Impact
- The core transaction value remains US$175 million as announced in December 2025; no new economic upside is introduced by this amendment.
- Clarification of beneficial ownership mitigates a specific regulatory risk regarding title to the subsidiary being sold, which could have stalled TSX-V approval.
- This news is expected given the timeline leading up to the May 15 shareholder vote and circular mailing in April.
- The market has already priced in the $175 million sale as a "Game Changer" event from December; this step is procedural rather than transformative.
- Risk remains on regulatory approvals (Chinese ODI) and the aggressive June 30 closing timeline given the complexity of cross-border lithium transactions.
