DENVER,Sept. 7, 2023/PRNewswire/ --Summit Materials, Inc.(NYSE: SUM) ("Summit," "Summit Materials," "Summit Inc." or the "Company") is pleased to announce it has entered into a definitive agreement with Cementos Argos S.A.

Summit Materials (PRNewsfoto/Summit Materials, Inc.)

Argos USA is among the largest cement producers by total installed capacity in its areas of operations, which include the Southeast, Mid-Atlantic, and Texas. With its asset footprint comprising four integrated cement plants, approximately 140 ready-mix plants and eight ports, Argos USA's portfolio is well positioned to capitalize on positive demand drivers across public infrastructure, residential, and commercial end-markets. Argos USA has a total installed cement grinding capacity of 9.6 million tons per annum with additional import capacity providing incremental scale and operational flexibility. Approximately 85% of Argos USA EBITDA is generated from its leading cement platform.

The combination of Summit and Argos USA will create the fourth-largest cement platform in the United States and accelerates Summit's 'Elevate Summit' strategy, enhancing the Company's materials-led approach and positioning it for even greater success with a national footprint and significantly improved scale. With a deeper and broader network of assets, Summit and its shareholders will benefit from geographic diversification, expanded operational and commercial capabilities, and the ability to better meet growing demand for high quality construction materials in the United States.

Under the terms of the agreement, Cementos Argos will receive approximately $1.2 billion in cash (~40% of transaction value) subject to closing adjustments, and approximately 54.7 million shares of Summit stock (~60% of transaction value), valuing Argos USA at approximately $3.2 billion based on Summit's closing share price of $36.00 as of September 6, 2023. The transaction reflects a pre-synergized enterprise value to EBITDA multiple of approximately 10x based on full year 2023 estimated EBITDA for Argos USA or below 8x on a post-synergies basis.

Anne Noonan, Summit Materials President and CEO said, "Combining Argos USA with Summit is a significant milestone as we execute against and accelerate our materials-led portfolio strategy. The transaction will extend our geographic reach into high growth markets, creating a leading cement enterprise nationwide, and bring together two talent-rich organizations to innovate and deliver value-added solutions for our customers. Financially, we have clear line of sight to achieving targeted synergies of more than $100 million annually as we unlock the full potential of this powerful combination. The Argos USA team has done an excellent job growing and operating its business, and we look forward to welcoming them, and their expertise, to the Summit family."

Jorge Mario Velasquez, Chairman of the Board at Cementos Argos SA said: "We are committed to strengthen and help shape the future of the combined company: we intend to be long-term shareholders. Our commitment to the success of this platform transcends the transaction itself. We believe in the growth potential and value generation that this transaction offers, and we want to actively participate jointly with the Summit family by contributing our knowledge and expertise to drive that growth."

Non-GAAP Financial Measures

美国证券交易委员会(SEC)注册ulates the use of "non-GAAP financial measures," such as Adjusted Net Income (Loss), Adjusted Diluted Net Income, Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Free Cash Flow, Net Leverage and Net Debt which are derived on the basis of methodologies other than in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). We have provided these measures because, among other things, we believe that they provide investors with additional information to measure our performance, evaluate our ability to service our debt and evaluate certain flexibility under our restrictive covenants. Our Adjusted Net Income (Loss), Adjusted Diluted Net Income, Adjusted Diluted EPS, Adjusted EBITDA, Further Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Free Cash Flow,Net Leverage and Net Debt may vary from the use of such terms by others and should not be considered as alternatives to or more important than net income (loss), operating income (loss), revenue or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance or to cash flows as measures of liquidity.

Adjusted EBITDA, Adjusted EBITDA Margin, and other non-GAAP measures have important limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP. Some of the limitations of Adjusted EBITDA are that these measures do not reflect: (i) our cash expenditures or future requirements for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, our working capital needs; (iii) interest expense or cash requirements necessary to service interest and principal payments on our debt; and (iv) income tax payments we are required to make. Because of these limitations, we rely primarily on our U.S. GAAP results and use Adjusted EBITDA, Adjusted EBITDA Margin and other non-GAAP measures on a supplemental basis.

调整后息税前利润,进一步调整后息税前利润,调整EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Adjusted Net Income (Loss), Adjusted Diluted Net Income, Adjusted Diluted EPS, Free Cash Flow, Net Leverage and Net Debt reflect additional ways of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliations to U.S. GAAP financial measures included in the tables attached to this press release, may provide a more complete understanding of factors and trends affecting our business. We strongly encourage investors to review our consolidated financial statements in their entirety and not rely on any single financial measure. Reconciliations of the non-GAAP measures used in this press release are included in the attached tables.
