The Merger

On January 18, 2016, Progressive Waste, Water Merger Sub LLC, a Delaware limited liability company and a wholly-owned subsidiary of Progressive Waste (“Merger Sub”), and Waste Connections, Inc., a Delaware corporation (“Waste Connections”), entered into an Agreement and Plan of Merger (the “Merger Agreement”).

The Merger is not conditioned upon approval of the consolidation by Progressive Waste’s shareholders.

Immediately following the Merger, Progressive Waste will amalgamate with a new, wholly-owned subsidiary of Progressive Waste with the resulting combined corporation assuming the name Waste Connections, Inc.

Upon the completion of the Merger, Waste Connections’ former stockholders will own approximately 70% of the combined company, and Progressive Waste shareholders will own approximately 30%. The merger is expected to close in the second quarter 2016.

WASTE CONNECTIONS AND PROGRESSIVE WASTE SOLUTIONS AGREE TO COMBINE TO CREATE LEADING SOLID WASTE SERVICES COMPANY FOCUSED ON DIFFERENTIATED MARKETS

Combination Brings Together Complementary Footprints under Proven Management Team with Long-Term Track Record of Shareholder Value Creation

Expects Combined Year 1 Adjusted EBITDA(A) between $1.25 Billion and $1.3 Billion and More Than $625 Million of Adjusted Free Cash Flow(B), Excluding the Impact of Any Divestitures and/or Asset Swaps

Transaction Expected to Generate Approximately $50 Million in SG&A Cost Savings and Additional Upside from Longer-Term Safety and Operational Improvements

Expects Over 20% Accretion in Year 1 Adjusted Free Cash Flow/Share

Stock-for-Stock Transaction Maintains Strong Credit Profile and Flexibility to Fund Future Growth Opportunities and Return of Capital to Shareholders

Joint Conference Call with Investment Community at 8:30 am ET Today

The Woodlands, Texas and Toronto, Ontario; January 19, 2016 - Waste Connections, Inc. (NYSE: WCN) and Progressive Waste Solutions Ltd. (NYSE: BIN) (TSX: BIN) today announced that they have entered into a definitive agreement to merge in an all-stock transaction. Upon the completion of the transaction, Waste Connections stockholders will own approximately 70% of the combined company, and Progressive Waste shareholders will own approximately 30%. The transaction has been unanimously approved by both companies’ Boards of Directors and is expected to close in the second quarter of 2016.

The transaction was negotiated on the basis of an implied exchange ratio of 0.4815 of a share of Waste Connections for each share of Progressive Waste. As a result of the transaction structure described below, Waste Connections stockholders will receive 2.076843 shares of Progressive Waste stock (1/0.4815) for each share of Waste Connections stock they own. The transaction value represents an approximately 16% premium to Progressive Waste’s 20-day volume-weighted average stock price prior to the announcement on January 4, 2016, that it was engaged in a review of strategic alternatives. Upon closing, the combined company will use the Waste Connections name and it is anticipated that its shares will trade on the New York Stock Exchange and the Toronto Stock Exchange.

“We are extremely excited to welcome Progressive Waste into the Waste Connections family and believe the combination will be quite compelling to our collective employees, shareholders and other stakeholders,” said Ronald J. Mittelstaedt, Chief Executive Officer and Chairman of Waste Connections. “Under our leadership, we believe we can instill the corporate culture, safety focus, operational excellence and accountability that have served us so well and which we believe are necessary for long-term success within Progressive Waste’s complementary markets. These improvements, together with expected immediate synergies and other cash flow benefits, should accelerate value creation for both companies’ shareholders. In addition, to maintain our strategic market differentiation and drive further value creation, we expect to either divest or swap assets within certain U.S. markets as we believe between 85% and 90% of Progressive Waste’s revenue is consistent with our differentiated tenets. Put simply, we believe this combination creates a company uniquely positioned with industry-leading operating and free cash flow margins, together with the balance sheet strength, to drive further growth and increase the return of capital to our shareholders.”

“Combining Progressive Waste and Waste Connections makes compelling strategic and financial sense, and the all-stock nature of the transaction provides Progressive Waste shareholders with the opportunity to participate in the significant near- and long-term upside potential of the combination,” said Joseph Quarin, President and Chief Executive Officer of Progressive Waste. “We believe this combination will accelerate the improvements already underway, building upon our fourth quarter financial and operational performance. Importantly, employees will benefit from new opportunities for growth and development as part of a larger company committed to customer service, operational excellence, safety and employee engagement. We look forward to a bright future for our employees and enhanced service for our customers as a result of this transaction.”

James J. Forese, Chairman of Progressive Waste’s Board of Directors, said, “Having conducted a review of the strategic options available to the company, the Special Committee and Board concluded that this transaction is in the best interest of Progressive Waste and enhances value for our shareholders. Together with Waste Connections and its leadership team, we create a new industry leader that is well positioned to serve a diverse base of customers across North America and capitalize on an expanded set of growth opportunities to generate substantial value for shareholders.”

Mr. Mittelstaedt added, “We welcome Progressive Waste’s talented employees and recognize their significant value to the customers and communities they serve. They have been critical to their company’s performance and growth and will continue to contribute to the combined company’s success.”

Strategic and Financial Benefits

The combination of Waste Connections and Progressive Waste is consistent with the strategic goals of both companies, and will create an industry leader with enhanced scale and a stronger financial profile.

·                  Expanded Operational Footprint. Following completion of the transaction, the combined company will have pro forma revenue of approximately $4.1 billion and operate an integrated network of solid waste operations across North America. The transaction brings together vertically integrated and complementary asset bases under Waste Connections’ disciplined market selection and safety-focused operational model.

·                  Strong and Diversified Revenue Streams. The transaction combines two entities that have delivered strong organic growth within the industry. The combined company will benefit from a diverse revenue base and will have strategic assets uniquely positioned for continued growth. The combination of Waste Connections’ differentiated position in mostly secondary and exclusive U.S. markets with Progressive Waste’s strong position in Canada and complementary U.S. markets, particularly in its commercial services line, will result in a high quality of revenue, margin and free cash flow.

·                  Meaningful Synergy Opportunities. The combination is expected to generate approximately $50 million in annualized SG&A cost savings within the first 12 months after closing, with operational and safety-related improvements and market rationalization contributing additional upside over the long-term. Tax-effected synergies, capex discipline and other cash flow benefits should result in over $625 million of adjusted free cash flow generation for the combined company in year 1, or more than 20% accretive on a free cash flow per share basis.

·                  Strong Financial Profile. As an all-stock transaction, leverage for the combined company should remain at approximately 3x debt to EBITDA upon completion of the transaction. This attractive credit profile, combined with sector-leading conversion of EBITDA to free cash flow, provides not only a strong financial foundation for our employees and communities, but also the ability to further enhance shareholder returns through additional growth opportunities and share repurchases.

·                  Continued Payment of Dividend. The strong free cash flow characteristics of the combined company support the continued payment of a quarterly dividend to shareholders. The dividend policy of the combined company will be subject to review by the Board of the combined entity upon closing of the transaction. Until the close of the transaction, both companies intend to continue to pay their respective quarterly dividends.

Management, Board and Headquarters

Upon completion of the transaction, the combined company will be led by Waste Connections’ current management team. The Board of Directors for the combined company will include the five current members of Waste Connections’ Board and two members from Progressive Waste’s current Board.

The combined company will maintain headquarters in The Woodlands, Texas and Canadian operating headquarters in Toronto, Ontario. Upon completion of the transaction, the combined company will be domiciled in Canada.

2

Transaction Structure and Approvals

The transaction is structured as a reverse merger pursuant to which Waste Connections will merge into a newly formed direct or indirect subsidiary of Progressive Waste. Under the terms of the definitive agreement, Waste Connections stockholders will receive 2.076843 Progressive Waste shares for each Waste Connections share they own. Subject to the approval of Progressive Waste’s shareholders, Progressive Waste then expects to implement immediately a share consolidation on the basis of 0.4815 (1 divided by the 2.076843 ratio above) of a share on a post-consolidation basis for each one share outstanding on a pre-consolidation basis. If the share consolidation is approved by Progressive Waste’s shareholders, Waste Connections stockholders will instead receive one share of the combined company for each existing Waste Connections share, resulting in approximately 174 million combined shares outstanding on a post-consolidation basis. Upon the completion of the transaction and irrespective of the outcome of the share consolidation approval, Waste Connections stockholders will own approximately 70% of the combined company, and Progressive Waste shareholders will own approximately 30%.

The transaction is expected to be taxable, for U.S. federal income tax purposes, to Waste Connections stockholders; the transaction is expected to be non-taxable to shareholders of Progressive Waste.

The transaction is subject to customary closing conditions, including the approval of both companies’ shareholders, U.S. antitrust approval and the approval of the Toronto Stock Exchange. The consummation of the combination transaction is not conditioned upon Progressive Waste shareholder approval of the share consolidation.

Further information regarding the transaction will be included in an information circular and/or proxy statement to be mailed to shareholders of both Progressive Waste and Waste Connections.

Time to Close

The transaction is expected to close in the second quarter of 2016.

Definitions

(A) Adjusted EBITDA: Adjusted EBITDA, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry. Waste Connections’ management uses adjusted EBITDA as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company’s operations. Waste Connections defines adjusted EBITDA as net income, plus income tax provision, plus interest expense, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any loss or gain on disposal of assets, plus other expense, less other income. The Company further adjusts this calculation to exclude the effects of other items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate adjusted EBITDA differently.

(B) Adjusted Free Cash Flow: Adjusted free cash flow, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a valuation and liquidity measure in the solid waste industry. Waste Connections’ management uses adjusted free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company’s operations. Waste Connections defines adjusted free cash flow as net cash provided by operating activities, plus proceeds from disposal of assets, plus or minus change in book overdraft, plus excess tax benefit associated with equity-based compensation, less capital expenditures for property and equipment and distributions to non-controlling interests. The Company further adjusts this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of its business. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Other companies may calculate adjusted free cash flow differently.
