EXFO Announces Substantial Issuer Bid

QUEBEC CITY, CANADA, January 7, 2015 — EXFO Inc. (NASDAQ: EXFO; TSX: EXF) announced today that its Board of Directors has authorized a substantial issuer bid (the “Offer”) to purchase for cancellation up to 7,142,857 subordinate voting shares for an aggregate purchase price not to exceed C$30,000,000.

The Offer is being made by way of a “modified Dutch Auction” pursuant to which shareholders may tender all or a portion of their shares (i) at a price not less than C$4.20 per share and not more than C$4.60 per share, in increments of C$0.05 per share, or (ii) without specifying a purchase price, in which case their shares will be purchased at the purchase price determined in accordance with the Offer. The Offer will expire at 5 p.m. (Eastern time) on February 13, 2015, unless withdrawn, extended or varied by EXFO.

The purchase price paid for each share properly tendered and not withdrawn will be based on the number of shares tendered and the prices specified by shareholders making tenders, and will be the lowest price that will allow EXFO to purchase up to C$30,000,000 of shares at a price within the range specified above. Shareholders will receive the purchase price in cash for shares tendered at prices equal to or lower than the purchase price. All shares tendered at prices higher than the purchase price will be returned to shareholders. All shares purchased by EXFO will be purchased at the same price, even if shareholders have selected a lower price. If the number of shares tendered at or below the purchase price would result in an aggregate purchase price in excess of C$30,000,000, those shares will be purchased on a pro rata basis.

The Offer is not conditional upon any minimum number of shares being tendered, but it is subject to certain other conditions. A complete description of the terms and conditions of the Offer will be contained in the Offer to Purchase and Issuer Bid Circular and related documents that will be filed with the applicable securities regulatory authorities in Canada and the United States and mailed to holders of shares on or about January 8, 2015.

EXFO has suspended its current normal course issuer bid and no subsequent purchases will be completed under such normal course issuer bid that expires on January 12, 2015.

EXFO has retained National Bank Financial Inc. and its U.S. affiliate to act as Dealer Managers in connection with the Offer. EXFO has retained Georgeson Shareholder Communications Canada Inc. and its U.S. affiliate to act as Information Agents in connection with the Offer.
