OTTAWA and SUNNYVALE, Calif., July 27, 2017 (GLOBE NEWSWIRE) — Mitel (Nasdaq:MITL) (TSX:MNW) and ShoreTel (Nasdaq:SHOR) today announced that they have entered into a definitive merger agreement pursuant to which Mitel will acquire 100% of the outstanding shares of ShoreTel common stock in an all-cash transaction at a price of $7.50 per share, or a total equity value of approximately $530 million and a total enterprise value of approximately $430 million. The purchase price represents a 28% premium to ShoreTel’s closing share price on July 26, 2017.

Stronger together as a global market leader in the rapidly growing UCaaS market

Continuing to deliver its move-to-the-cloud strategy, with this transaction Mitel is accelerating on a growth path by investing further and faster into the UCaaS (Unified Communications as a Service) market as digital transformation accelerates customer demand for cloud-based solutions globally. The combined company will be the #2 player in the UCaaS market, creating a supplier with the scale and technical capabilities to enable customers with new cloud-based solutions and applications.

The combined company will be headquartered in Ottawa, Canada, and will operate as Mitel. Rich McBee, Mitel’s Chief Executive Officer, will lead the combined organization. Steve Spooner, Mitel’s Chief Financial Officer, will also continue in that role.

“This is a very natural combination that enables us to continue to consolidate the industry and take advantage of cost synergy opportunities while adding new technologies and significant cloud growth to our business,” said Mitel CEO, Rich McBee. “Together, Mitel and ShoreTel will be able to take customers to the cloud faster with full-featured, cloud-based communications and applications.”

Uniquely qualified to take customers and partners to the cloud

Together, the combined company will have approximately 3,200 channel partners and an industry-leading portfolio of communications and collaboration solutions. Mitel and ShoreTel are committed to providing continued support and an attractive path forward for all customers and partners – cloud and premise. On closing of the proposed transaction, the combined company will have a global workforce of approximately 4,200 employees.

“With the announcement today, this concludes our comprehensive review of strategic alternatives by delivering a significant cash premium for our shareholders,” said Don Joos, CEO of ShoreTel. “Customers are clearly moving to the cloud at a rapid pace. The combination of Mitel and ShoreTel creates a new UCaaS market leader with a differentiated strategy and solution, and a clear migration path so that no customer is left behind or will have to abandon what they already have to cloud-enable their organization.”

Once the transaction is complete, Mitel will be uniquely positioned to offer all customers the advantages of cloud-based communications. For enterprise customers, ShoreTel’s solutions will strengthen Mitel’s ability to cloud-enable customers with existing premise or mixed estate deployments, creating the technical foundation needed for delivery of next-generation cloud applications.

Size, scale and financial foundation to drive growth

Financial highlights of the transaction include:

• Combined sales of $1.3 billion*
• Increases Mitel’s total recurring revenue to 39% of total revenue*
• More than doubles Mitel’s UCaaS revenue to $263 million*
• Significant synergy opportunity targeted at $60M in annual run rate spend expected to be achieved over two years
• Expected to be accretive to non-GAAP EPS in the first year

*based on trailing twelve months combined to March 31, 2017

Transaction Details

The transaction will be completed through a cash tender offer for all of the outstanding shares of ShoreTel common stock, followed by a merger, which will not require approval of ShoreTel’s stockholders, in which remaining shares of ShoreTel common stock will be converted into the right to receive the same $7.50 cash per share price paid in the tender offer.  ShoreTel’s Board of Directors has recommended that ShoreTel stockholders tender their shares in the offer. In connection with the execution of the merger agreement, ShoreTel’s directors and executive officers, have entered into tender support agreements with Mitel pursuant to which they have agreed to tender their shares to Mitel’s offer.

Mitel intends to finance the consideration for the acquisition and associated transaction expenses using a combination of cash on hand from the combined business, drawings on its existing revolving credit facility and proceeds from a new fully underwritten $300 million term loan maturing in 2023.  The existing term loan and revolving credit facility will remain in place, with the Company having already obtained the requisite majority consent to certain amendments which accommodate the acquisition and the incremental financing. BMO Capital Markets is leading the new term loan facility with Citizens Bank, N.A., HSBC Bank Canada and Canadian Imperial Bank of Commerce serving as Joint Lead Arrangers and Joint Bookrunners.  Citizens Bank, N.A., lead on the existing amended facilities, will act as administrative agent for these and the new term loan.  EA Markets LLC provided Mitel with independent advisory and transaction services in conjunction with the arrangement and structuring of the new financing.

The transaction is expected to be completed in the third quarter of 2017, subject to ShoreTel stockholders having tendered shares representing more than 50% of the outstanding shares of ShoreTel common stock, certain regulatory approvals having been obtained and other customary conditions to the tender offer having been satisfied.

Jefferies LLC is serving as financial advisor to Mitel, Paul, Weiss, Rifkind, Wharton & Garrison LLP is serving as legal advisor to Mitel and Osler, Hoskin & Harcourt LLP is serving as legal advisor to Mitel in connection with the financing.  J.P. Morgan Securities LLC is serving as financial advisor to ShoreTel and Fenwick & West LLP is serving as legal advisor to ShoreTel.

Non-GAAP Financial Measures

In an effort to provide investors with additional information regarding Mitel’s results as determined by generally accepted accounting principles (GAAP), Mitel also discusses, in its press releases and presentation materials, non-GAAP information which Mitel’s management believes provides useful information to investors, including Adjusted EBITDA, non-GAAP net income, non-GAAP EPS (earnings per share) or non-GAAP net income per common share and Constant Currency. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. We use these non-GAAP financial measures to assist management and investors in understanding our past financial performance and prospects for the future, including changes in our operating results, trends and marketplace performance, exclusive of unusual events and other factors which do not directly affect what we consider to be our core operating performance. Non-GAAP measures are among the primary indicators management uses as a basis for our planning and forecasting of future periods. Investors are cautioned that non-GAAP financial measures should not be relied upon as a substitute for financial measures prepared in accordance with U.S. generally accepted accounting principles. Mitel provides a reconciliation between GAAP and non-GAAP financial information in our quarterly results announcements and in the supplemental slides used in conjunction with Mitel’s quarterly calls. This information is available on our website at www.mitel.com under the “Investor Relations” section http://investor.mitel.com/events.cfm.
