Mitel Announces TSX Acceptance of Normal Course Issuer Bid

Management Authorized to Repurchase up to Approximately 7.8 Million Common Shares

OTTAWA, March 07, 2017 (GLOBE NEWSWIRE)

Mitel® (Nasdaq:MITL) (TSX:MNW), a global leader in business communications, today announced that its Board of Directors has authorized a share buyback program.  In a filing with the Toronto Stock Exchange (the "TSX"), the TSX has accepted the company's Notice of Intention to Make a Normal Course Issuer Bid (the "Notice"). Pursuant to the Notice, Mitel may purchase up to 7,816,574 Mitel Common Shares (the "Bid"), representing approximately 10% of its public float. As of February 28, 2017, Mitel had 122,036,009 issued and outstanding Common Shares, including a public float of 78,165,743 Common Shares. During the previous 12 months, Mitel has not purchased any of its Common Shares.

"Mitel is committed to delivering shareholder value," said Richard McBee, Chief Executive Officer. "This share buyback program provides us with another lever to realize and maximize that value."

Mitel may purchase its Common Shares, from time to time, if it believes that the market price of its Common Shares is attractive and that the purchase would be an appropriate use of corporate funds and in the best interests of the Corporation. Common Shares purchased pursuant to the Bid will be cancelled. Mitel believes that having the ability to acquire Common Shares under the Normal Course Issuer Bid will present an attractive opportunity to utilize Mitel's available funds. The Normal Course Issuer Bid is intended to permit the Company to reduce its total number of issued and outstanding Common Shares, thereby benefiting all shareholders by increasing their relative equity interests in Mitel.

The Bid will commence on March 9, 2017 and will terminate no later than March 8, 2018. All purchases of Common Shares under the Bid may be made on the TSX or on alternative Canadian trading systems at the market price at the time of purchase in accordance with the requirements of the TSX or on the NASDAQ in compliance with Canadian securities law requirements for issuer repurchases through other public markets and Rule 10b-18 under the U.S. Securities Exchange Act of 1934. Purchases may also be made by such other means as may be permitted by the TSX and in compliance with Canadian securities laws, including by private agreement pursuant to an issuer bid exemption order issued by a securities regulatory authority. Purchases made by way of such private agreements under an issuer bid exemption order will be at a discount to the prevailing market price. The rules and policies of the TSX contain restrictions on the number of shares that can be purchased under the Bid, based on the average daily trading volumes of the Common Shares on the TSX. Similarly, the safe harbor conditions of Rule 10b-18 impose certain limitations on the number of shares that can be purchased on the NASDAQ per day. As a result of such restrictions, subject to certain exceptions for block purchases, the maximum number of shares which can be purchased per day during the Bid on the TSX is 30,357 based on 25% of the average daily trading volume for the prior six calendar months (being 121,429 Common Shares on the TSX). Subject to certain exceptions for block purchases, the maximum number of shares which can be purchased per day on the NASDAQ will be 25% of the average daily trading volume for the four calendar weeks preceding the date of purchase.

Subject to regulatory requirements, the actual number of Common Shares purchased and the timing of such purchases, if any, will be determined by Mitel having regard to future price movements and other factors. All purchases will be subject to Mitel's normal trading blackouts.
