TIDEWATER MIDSTREAM AND INFRASTRUCTURE LTD. ANNOUNCES EFFECTIVE DATE OF SHARE CONSOLIDATION

CALGARY, AB, Aug. 21, 2025 /CNW/ - Tidewater Midstream and Infrastructure Ltd. ("Tidewater" or the "Corporation") (TSX: TWM) announces that, further to the special resolution approved by the Corporation's shareholders at the annual general and special meeting held on May 27, 2025, the board of directors of the Corporation has determined to implement the consolidation of the Corporation's common shares (the "Common Shares") on the basis of one (1) post-consolidation Common Share for every twenty (20) pre-consolidation Common Shares (the "Consolidation"). The expected effective date for the Consolidation is August 28, 2025.

The Toronto Stock Exchange ("TSX") has conditionally approved the Consolidation, and the Common Shares are expected to commence trading on the TSX on a post-Consolidation basis within 2 or 3 business days following the receipt and acceptance of materials by the TSX.

The Common Shares will continue to be listed on the TSX under the symbol "TWM" on a post-Consolidation basis under a new CUSIP and new ISIN. No fractional Common Shares will be issued as a result of the Consolidation. Any fractional Common Shares resulting from the Consolidation will be rounded to the nearest whole Common Share with fractions equal to and above 0.5 being rounded up to the nearest whole Common Share and fractions below 0.5 being rounded down to the nearest whole Common Share.

As a result of the Consolidation, the number of outstanding Common Shares will be reduced from 431,890,308 pre-Consolidation Common Shares to approximately 21,594,515 post-Consolidation Common Shares, subject to adjustments for rounding. Proportionate adjustments have been made to the conversion price of the Corporation's outstanding convertible unsecured subordinated debentures (the "Debentures") in accordance with the trust indenture dated June 4, 2024, as well as the Corporation's stock options (and exercise prices), restricted share units, performance share units and deferred share units in accordance with the terms and conditions of the respective plans under which they are issued.

TSX Trust Company ("TSX Trust"), the Corporation's transfer agent, will act as the exchange agent for the Consolidation. Tidewater's registered shareholders holding their Common Shares in certificated form will receive a letter of transmittal from TSX Trust in respect of the Consolidation, which each such registered shareholder will need to sign and complete. If such a registered shareholder does not receive a letter of transmittal, a copy of the letter of transmittal will be available under Tidewater's SEDAR+ profile on www.sedarplus.ca. The letter of transmittal will contain instructions on how to surrender certificates representing pre-Consolidation Common Shares and authorize TSX Trust to issue a certificate representing their post-Consolidation Common Shares. Registered shareholders whose Common Shares are represented by a direct registration advice(s) ("DRS") will not need to complete and sign a letter of transmittal, and a DRS statement representing their post-Consolidation Common Shares will automatically be issued to such registered shareholder by TSX Trust.

Non-registered shareholders who hold their Common Shares through an intermediary such as a bank, trust company, securities dealer or broker should note that these intermediaries may have their own procedures for processing the Consolidation which may differ from those described above for registered shareholders. Non-registered shareholders who have questions should contact their intermediary for more information.

Further details on the Consolidation are contained in the Corporation's management information circular dated April 7, 2025, a copy of which is available under Tidewater's profile on www.sedarplus.ca.
