Interfor Amends Share Buyback Program

Press Release

INTERFOR CORPORATION (“Interfor” or the “Company”) (TSX: IFP) announced today that the Toronto Stock Exchange (“TSX”) has accepted a notice filed by the Company of its intention to amend its normal course issuer bid (“NCIB”).

The amended NCIB will allow for the purchase during the twelve-month period that commenced on March 7, 2018 and ends on March 6, 2019 of up to 6,934,356 common shares, which represents 10% of the Company’s public float as at March 1, 2018. The amended NCIB increases the maximum number of common shares that may be repurchased by an additional 3,434,356 common shares. Under the current NCIB, as of market close on December 18, 2018, the Company purchased 2,148,130 common shares at an average price of $16.34 per common share, resulting in 4,786,226 common shares available for purchase under the amended NCIB.

Under TSX rules, Interfor will be allowed to purchase daily a maximum of 64,705 common shares, representing 25% of the average daily trading volume of 258,822 common shares, subject to certain exemptions for block purchases. All purchases will be made through open market transactions through the facilities of the TSX or other Canadian alternative trading systems and will conform to their rules and regulations. The price to be paid by Interfor for any common shares will be the market price at the time of acquisition. All common shares purchased pursuant to the NCIB will be cancelled.

Interfor has also entered into an automatic securities purchase plan agreement with a securities broker under which the broker will act as the Company’s agent to acquire Interfor common shares under the NCIB during the Company’s blackout period starting on January 1, 2019 and ending on February 11, 2019. Purchases by the broker under the NCIB during this period will be made at the broker’s discretion, subject to certain parameters established by Interfor prior to January 1, 2019 with respect to price and number of common shares.

The Company believes that, from time to time, the market price for its common shares may be attractive and their purchase would represent a desirable use of capital to increase shareholder value.
