SANTIAGO, Chile, March 13, 2023 — Guacolda Energía SpA (f/k/a Empresa Eléctrica Guacolda S.A., the “Company“) announced today that it has commenced a tender offer to purchase for cash (the “Tender Offer“) its 4.560% Senior Notes due 2025 (CUSIP Nos. 29244U AF5 / P3711H AF6; ISINs US29244UAF57 / USP3711HAF66) (the “Notes“) for an aggregate purchase price up to U.S.$80,000,000, excluding Accrued Interest (as defined below) and any additional amounts as set forth in the Offer to Purchase (as defined below) (such purchase price, subject to increase by the Company, the “Aggregate Maximum Purchase Price“), upon the terms and subject to the conditions described in the offer to purchase dated March 13, 2023 (as it may be amended or supplemented from time to time, the “Offer to Purchase“). Terms used in this announcement and not otherwise defined have the meanings assigned to them in the Offer to Purchase.

The following table sets forth certain terms of the Tender Offer:

The Tender Offer will expire at 5:00 p.m., New York City time, on April 11, 2023, unless amended, extended or terminated by the Company (the “Expiration Date“). The Tender Offer may be amended, extended or terminated.

Subject to the terms and conditions of the Tender Offer, the consideration for each $1,000 principal amount of the Notes validly tendered and accepted for purchase pursuant to the Tender Offer will be the Tender Offer Consideration set forth in the above table. Holders of Notes that are validly tendered at or prior to 5:00 p.m., New York City time, on March 24, 2023 (subject to extension, the “Early Tender Time“) and accepted for purchase pursuant to the Tender Offer will receive the Total Consideration set forth in the above table, which includes the Tender Offer Consideration plus the early tender premium set forth in the Offer to Purchase (the “Early Tender Premium“). Holders of Notes tendered after the Early Tender Time, but before the Expiration Date, and accepted for purchase pursuant to the Tender Offer will receive the Tender Offer Consideration, but not the Early Tender Premium. No tenders will be valid if submitted after the Expiration Date.

All Holders of Notes accepted for purchase pursuant to the Tender Offer will also receive accrued and unpaid interest, if any, on such Notes from the last interest payment date with respect to those Notes to, but not including, the applicable settlement date (“Accrued Interest“), and any additional amounts as set forth in the Offer to Purchase.

Tendered Notes may be withdrawn from the Tender Offer prior to, but not after, 5:00 p.m., New York City time, on March 24, 2023, unless extended by the Company (the “Withdrawal Deadline“). Holders of Notes, who tender their Notes after the Withdrawal Deadline, but at or prior to the Expiration Date, may not withdraw their tendered Notes.

The early settlement date will be determined at the Company’s option and is currently expected to occur on March 28, 2023. Subject to the Aggregate Maximum Purchase Price and proration, the Company intends to purchase any remaining Notes that have been validly tendered, accepted for purchase in the Tender Offer and not validly withdrawn promptly following the Expiration Date, subject to all conditions to the Tender Offer having been either satisfied or waived by the Company. The final settlement date is expected to occur on the second business day following the Expiration Date. If the Company does not elect to have an early settlement date, payment for Notes validly tendered at or prior to the Early Tender Time and accepted for purchase will be made on the final settlement date.

Acceptance of tenders of the Notes may be subject to proration if the aggregate purchase price of Notes validly tendered would cause the Aggregate Maximum Purchase Price to be exceeded. Furthermore, if the aggregate purchase price exceeds the Aggregate Maximum Purchase Price at or prior to the Early Tender Time, Holders who validly tender Notes after the Early Tender Time will not have any of their Notes accepted for purchase. If proration of the tendered Notes is required, the Company will determine the final proration factor as soon as practicable after the Early Tender Time or the Expiration Date, as applicable. Any Notes that are tendered and accepted in the Tender Offer will be retired and canceled.

Notwithstanding any other provision of the Tender Offer, the Company’s obligation to accept for purchase, and to pay for, any Notes validly tendered pursuant to the Tender Offer, is conditioned upon satisfaction of the General Conditions (as defined in the Offer to Purchase) and the satisfaction of the Secured Financing Condition (as defined in the Offer to Purchase). The General Conditions to the Tender Offer and the Secured Financing Condition are for the sole benefit of the Company and may be asserted by the Company, regardless of the circumstances giving rise to any such condition (including any action or inaction by the Company). The Company reserves the right, in its sole discretion, to waive any and all conditions of the Tender Offer, at or prior to the Expiration Date (or the Early Settlement Date, if the Company elects to have an early settlement). The Tender Offer is not subject to a minimum aggregate principal amount of Notes being tendered.

The Company reserves the right, subject to applicable law, to (a) extend the Early Tender Time, Withdrawal Deadline or Expiration Date to a later date and time as announced by the Company; (b) increase the Aggregate Maximum Purchase Price without extending the Withdrawal Deadline or otherwise reinstating withdrawal rights of Holders except as required by applicable law; (c) waive or modify in whole or in part any and all conditions to the Tender Offer; (d) delay the acceptance for purchase of any Notes or delay the purchase of any Notes; or (e) otherwise modify or terminate the Tender Offer. In the event that the Tender Offer is terminated or otherwise not completed, the Total Consideration or Tender Offer Consideration, as the case may be, relating to the Notes, will not be paid or become payable to Holders of such Notes, without regard to whether such Holders have validly tendered their Notes (in which case, such tendered Notes will be promptly returned to Holders). The Company will publicly announce any extension, amendment or termination in the manner described in the Offer to Purchase. There can be no assurance that the Company will exercise its right to extend, terminate or amend the Tender Offer.

In the event that the Company modifies the Tender Offer Consideration, the Early Tender Premium, or the Total Consideration, and there are fewer than 10 business days remaining from and including the date of the announcement of such modification to the Expiration Date, the Company will extend the Expiration Date so that at least 10 business days remain until the Expiration Date with respect to the Tender Offer.
