SINTANA ENERGY ANNOUNCES RESULTS OF WARRANT EXERCISE ACTIVITY -– APPROXIMATELY 99% EXERCISE RATE GENERATING $22.5MM IN ADDITIONAL CASH RESOURCES

Sintana Energy Inc. has released the results of warrant exercise activity through the expiry and delisting of the company's traded warrants that occurred on Friday, March 8, 2024.

Sintana issued approximately 92.9 million warrants in conjunction with a financing undertaken by the company in March, 2022. The two-year warrants, struck at an exercise price of 25 cents per share, were listed and traded on the TSX Venture Exchange under the ticker SEI.WT until Friday, March 8, 2024, when they expired and were delisted.

In the period leading up to the expiry, approximately 91.6 million warrants were exercised, generating approximately $22.5-million in additional cash resources for the company -- an exercise rate of approximately 99 per cent.

"We are grateful for the continuing support of our shareholders. The company's progress over the past 24 months and its resulting impact on our share price performance continue to demonstrate the timeliness of our entry into Namibia," said Robert Bose, chief executive officer of Sintana. "The near-complete exercise of the warrants are a further testament to that. We look forward to further progress as we build off of the two light-oil discoveries we announced this past January."
