PetroTal Announces Renewal of Share Buyback Program

Calgary, AB and Houston, TX - May 30, 2025 - PetroTal Corp. ("PetroTal" or the "Company") (TSX: TAL, AIM: PTAL and OTCQX: PTALF) is pleased to announce the renewal of its normal course issuer bid (the "NCIB"), following approval by the Toronto Stock Exchange ("TSX"). All amounts are in US dollars unless stated otherwise.

PetroTal expects that the NCIB will continue to provide an additional tool to enhance total long-term shareholder returns. The Company believes that, at times, the prevailing share price does not reflect the underlying value of its common shares ("Common Shares") and the repurchase of Common Shares for cancellation represents an attractive opportunity to improve PetroTal's per share metrics and thereby increase the value of the Common Shares. 

The NCIB allows PetroTal to purchase up to 45,776,656 Common Shares, representing approximately 5% of its 914,988,946 issued and outstanding Common Shares as at May 26, 2025, over a 12-month period commencing on June 3, 2025 and ending no later than June 2, 2026. Under the NCIB, purchases of Common Shares may be made through the facilities of the TSX, alternative trading systems in Canada, if eligible, and AIM, a market operated by the London Stock Exchange in accordance with applicable regulatory requirements. Purchases under the NCIB will be made through open market transactions at market price, as well as by other means as may be permitted under applicable securities laws. The actual number of Common Shares that may be purchased under the NCIB and the timing of any such purchases will be determined by management of the Company. Any Common Shares purchased under the NCIB will either be cancelled or, where appropriate, temporarily held in treasury to satisfy employee share awards.

Under the TSX rules, the total number of Common Shares PetroTal is permitted to purchase on the TSX is subject to a daily purchase limit of 163,942 Common Shares (representing 25% of the average daily trading volume of 655,771 Common Shares on the TSX calculated for the six months ended April 30, 2025); provided that PetroTal may make one block purchase per calendar week that exceeds such limits.

In connection with the NCIB, the Company renewed a buyback agreement with Stifel Nicolaus Europe Limited ("Stifel"), who will continue to conduct the NCIB on PetroTal's behalf and entered into an automatic purchase plan (the "ASPP") with Stifel. The ASPP allows for the purchase of Common Shares under the NCIB at times when PetroTal would ordinarily not be permitted to purchase Common Shares due to regulatory restrictions and self-imposed blackout periods. Stifel intends to instruct Stifel Nicolaus Canada Inc. as its agent to conduct purchases of Common Shares on the TSX. Under the ASPP, before entering into a blackout period, PetroTal may, but is not required to, instruct Stifel to make purchases under the NCIB within specified parameters. Such purchases would be at the discretion of Stifel based on parameters provided by the Company prior to the blackout period in accordance with the terms of the ASPP and in compliance with the rules and regulations of the TSX, AIM and applicable securities laws. Any purchase of Common Shares on the TSX or alternate trading systems in Canada will continue to be completed by Stifel Nicolaus Canada Inc. acting as agent for Stifel. The ASPP has been pre-cleared by the TSX. All purchases made pursuant to the terms of the ASPP will be included in computing the number of Common Shares purchased under the NCIB. Outside any blackout period, Common Shares may be purchased under the NCIB based on the discretion of the Company's management in compliance with applicable exchange rules and securities laws.

The Company was permitted to repurchase up to 14,600,000 Common Shares under its current NCIB that commenced on May 23, 2024 and ended on May 22, 2025. As at May 20, 2025, the Company had repurchased an aggregate 5,361,533 Common Shares under the expiring NCIB on the open market at a volume weighted average price per Common Share of approximately USD$0.4669 per share.
