Altus expects to take up 2.84 million shares in SIB

Ms. Camilla Bartosiewicz reports ALTUS GROUP ANNOUNCES PRELIMINARY RESULTS OF SUBSTANTIAL ISSUER BID Altus Group Ltd. has released the preliminary results of its substantial issuer bid (SIB), pursuant to which Altus Group offered to purchase for cancellation a number of its common shares for an aggregate purchase price not to exceed $350-million at a purchase price of not less than $50 and not more than $57 per share. The SIB expired at 5 p.m. Toronto time on Thursday, Jan. 8, 2026. Preliminary results of SIB In accordance with the terms and conditions of the SIB and based on the preliminary calculation of TSX Trust Company as depositary for the SIB, Altus Group expects to take up and pay for approximately 2,849,643 shares at a price of $57 per share under the SIB, representing an aggregate purchase price of approximately $162.43-million and approximately 6.59 per cent of the total number of Altus Group's issued and outstanding shares (net of escrowed shares) before giving effect to the SIB and on a non-diluted basis. Approximately 60,000 shares were tendered through notices of guaranteed delivery. Based on the depositary's preliminary calculation, approximately 6,561,903 shares were validly tendered and not withdrawn (including pursuant to proportionate tenders). None of Altus Group's directors or executive officers participated in the SIB. As the total value of shares tendered was less than the total that could have been purchased by the company under the terms of the SIB, all shares validly deposited and not withdrawn will be purchased under the SIB in accordance with its terms and no proration will be required. Shareholders who made valid proportionate tenders will have such number of shares purchased by Altus Group as would permit such shareholders to maintain their same share ownership percentage as existed prior to completion of the SIB (subject to rounding to avoid the purchase of fractional shares). Approximately 255,611 shares are anticipated to be taken up and purchased pursuant to proportionate tenders. After giving effect to the SIB, Altus Group expects to have approximately 40,377,617 shares issued and outstanding (net of 79,328 escrowed shares). The number of shares expected to be purchased, the purchase price and the aggregate purchase price referred to above are preliminary and remain subject to verification by the depositary. Upon take-up and payment of the shares purchased, Altus Group will release the final results. Payment for the shares accepted for purchase will be made in accordance with the terms of the offer and applicable law. Altus Group has not elected to extend the SIB, and the SIB expired on the expiration time, which, for greater certainty, was at 5 p.m. Toronto time on Thursday, Jan. 8, 2026. The full details of the SIB are described in the offer to purchase and issuer bid circular dated Nov. 26, 2025, as well as the related letter of transmittal and notice of guaranteed delivery, copies of which were filed and are available under Altus Group's profile on SEDAR+.
