TORONTO, Oct. 3, 2023 /PRNewswire/ -- Tecpetrol Investments S.L. ("Tecpetrol"), a member of the Techint Group, announces today that it has extended the expiry time of its board-supported offer (the "Offer") to acquire all of the issued and outstanding common shares of Alpha Lithium Corporation ("Alpha") for C$1.48 in cash per share to 5:00 p.m. (Vancouver time) on 20 October 2023. Shareholders using a broker may have an earlier cut-off time and are urged to tender their shares immediately. Shareholders who do not tender their shares will not receive the enhanced offer price under the Offer.

On 28 September 2023, the Special Committee and Board of Directors of Alpha, after receiving a positive independent fairness opinion from PI Financial Corp., publicly announced their unanimous recommendation that shareholders tender their shares to the Offer. Since then, a significant number of shares have been tendered to the Offer. Tecpetrol has also received feedback from a substantial number of Alpha shareholders expressing their desire to tender their Alpha shares to the Offer, but that they encountered difficulties tendering through their brokers in advance of their brokers' cut-off times on account of the date on which Alpha's unanimous Board support was announced and the Canadian federal holiday on 2 October 2023. As a result, Tecpetrol has extended the Offer to provide Alpha shareholders who have not yet tendered their shares to the Offer with additional time to do so, taking into account the upcoming Canadian Thanksgiving holiday weekend and anticipated brokers' cut-off times for the extended expiry date.

As previously disclosed, the Offer represents Tecpetrol's best and final offer to Alpha shareholders. No further extensions are contemplated.

It is a non-waivable condition of the Offer that there be validly deposited under the Offer more than 50% of the outstanding Alpha shares, excluding Alpha shares owned by Tecpetrol and its joint actors. If this legally required minimum tender condition is not satisfied by the expiry time of 5:00 p.m. (Vancouver time) on 20 October 2023, no Alpha shares will be acquired by Tecpetrol and Alpha shareholders will not be able to participate in the Offer.

Shareholders should be aware that if the Offer is not successful, they will face significant risks as Alpha shareholders, as described in Tecpetrol's Notice of Variation and Extension dated 22 September 2023. Since the announcement of the Offer, comparable lithium developer peers have traded down 43%¹, while Alpha is up 22% as of 3 October 2023. Tecpetrol believes that Alpha's share price may suffer significant downward pressure if the Offer is not completed.

How to Tender Q&A

Q:        How do I tender my Alpha shares?

A:        Shareholders whose shares are registered in the name of an investment advisor, stock broker, bank, trust company or other intermediary should immediately contact that intermediary for assistance if they wish to accept the Offer so that the necessary steps can be taken to enable the deposit of such shares under the Offer. Intermediaries likely have established tendering cut-off times that are prior to the expiry time. Shareholders must instruct their intermediaries promptly if they wish to tender.

Registered shareholders who own Alpha Lithium share certificates or DRS statements representing their shares and wish to accept the Offer must properly complete and execute the Letter of Transmittal that accompanied the original take-over bid circular dated 8 June 2023 (printed on YELLOW paper) and deposit it, at or prior to the Expiry Time, together with certificate(s) or DRS Statements representing their Alpha shares and all other required documents, with Laurel Hill Advisory Group, the Depositary and Information Agent, at its office in Toronto, Ontario specified in the Letter of Transmittal in accordance with the instructions set forth in the Letter of Transmittal.  These materials are also available on SEDAR+ under Alpha's profile at www.sedarplus.ca.

Q:        Who can I call if I have questions or require assistance in tendering my shares?

A:        Shareholders who have questions or require assistance in tendering their Alpha shares may contact Laurel Hill Advisory Group, the Depositary and Information Agent for the Offer, by telephone toll-free inside North America at 1-877-452-7184, or outside North America at 1-416-304-0211, or by email at assistance@laurelhill.com.

Q:        What is the deadline for me to instruct my broker to tender my Alpha shares?

A:        The Offer has been extended and is now open for acceptance until 5:00 p.m. (Vancouver time) on 20 October 2023. Shareholders whose shares are registered in the name of an investment advisor, stock broker, bank, trust company or other intermediary should immediately contact that intermediary for assistance if they wish to accept the Offer so that the necessary steps can be taken to enable the deposit of such shares under the Offer. Intermediaries likely have established tendering cut-off times that are prior to the expiry time. Shareholders must instruct their intermediaries promptly if they wish to tender.

Tecpetrol will be filing a Second Notice of Extension in respect of the extension of the expiry time to 5:00 p.m. (Vancouver time) on 20 October 2023 that will be available on SEDAR+ under Alpha's profile at www.sedarplus.ca and will be mailed to Alpha shareholders in accordance with applicable law.  Tecpetrol encourages Alpha shareholders to read the full details of the Offer and other important information set forth in the Second Notice of Extension, which should be read in conjunction with the take-over bid circular dated 8 June 2023, the notice of variation and extension dated 22 September 2023 and related offer documents.  These materials, which contain information on how to tender to the Offer, are available on SEDAR+ under Alpha's profile at www.sedarplus.ca.
