TORONTO, ON–(Marketwired – May 19, 2017) – STT Enviro Corp. (“STT“) (TSX VENTURE: STT) and Carmeuse Lime (Canada) Limited (“Carmeuse“) are pleased to announce today that Carmeuse’s offer to acquire all of the issued and outstanding common shares of STT (the “Shares“) for C$0.315 per Share by way of a take-over bid (the “Offer“) has been accepted by holders of Shares representing approximately 91.9% of the total number of Shares outstanding. As such, the minimum tender requirement under applicable Canadian securities laws has been satisfied and all other conditions to the Offer have been satisfied.

Computershare Investor Services Inc. (the “Depositary“) has reported that as at 5:00 p.m. (Toronto time) on May 19, 2017 the expiry of the initial deposit period of the Offer, a total of 42,358,857 Shares were validly deposited under the Offer and not withdrawn. Carmeuse has taken up and accepted for payment all such Shares and payment for such Shares will be made as soon as practicable, and in any event not later than May 25, 2017. If Shares were tendered through brokers or financial intermediaries, holders of such Shares will receive payment for their Shares through their broker or financial intermediary.

Carmeuse is extending the Offer until 5:00 p.m. (Toronto time) on June 5, 2017, which period includes the mandatory 10-day extension period under applicable Canadian securities laws, unless further extended, to allow STT shareholders who have not yet tendered their Shares to the Offer (the “Shareholders“) an opportunity to do so.

Carmeuse will file and mail to Shareholders a notice of variation regarding the extension of the expiry time of the Offer to 5:00 p.m. (Toronto time) on June 5, 2017, unless the Offer is further extended. Carmeuse will take up and pay for Shares validly deposited to the Offer during the extension period within 10 calendar days after any such deposit.

For clarity, STT shareholders who validly deposited their Shares to the Offer prior to 5:00 p.m. on May 19, 2017 do not need to take any further action to accept the Offer.

Following the expiry of the Offer, as extended, it is Carmeuse’s intention to enter into one or more transactions to enable Carmeuse or an affiliate of Carmeuse to acquire all Shares not acquired pursuant to the Offer. Shareholders who have not deposited or do not deposit their Shares pursuant to the Offer prior to 5:00 p.m. (Toronto time) on June 5, 2017 will continue to hold Shares. As a result of the Offer, Carmeuse currently holds more than 66 ²/₃% of the issued and outstanding Shares which will limit the ability of Shareholders, subject to the provisions of applicable Canadian securities laws, to control the actions of STT.

The full details of the Offer are contained in Carmeuse’s take-over bid circular and related Offer materials. Copies of the notice of variation, the take-over bid circular and related Offer materials, as well as STT’s directors’ circular, are available on STT’s SEDAR profile at www.sedar.com.
