Arcosa, Inc. Announces Completion of ACG Materials Acquisition, Initiation of Quarterly Dividend, and Establishment of Share Repurchase Authorization

• ACG Materials Acquisition Adds Specialty Materials and Aggregates Platforms Serving Attractive Infrastructure Markets
• Dividend and Share Repurchase Authorization Add Key Elements of Capital Allocation Strategy

Arcosa, Inc. ACA ("Arcosa" or the "Company"), a provider of infrastructure-related products and solutions, today announced that it has completed the acquisition of ACG Materials ("ACG"), and that its Board of Directors has approved the initiation of a cash dividend and the establishment of a share repurchase authorization.

On December 5^th, Arcosa completed the previously announced acquisition of ACG, a producer of specialty materials and aggregates. The purchase price of approximately $315 million was funded with a combination of cash on-hand and a $180 million borrowing under Arcosa's $400 million five-year credit facility. Based on ACG's estimated revenues of $152 million and adjusted EBITDA of $32 million for the trailing twelve month period ended August 31, 2018, this combination is expected to increase the current annualized revenues of Arcosa's Construction Products segment by approximately 50%, to $450 million, and be slightly accretive to EPS in 2019.

The Company plans to update its fiscal 2019 revenue and EBITDA guidance for the acquisition once it has additional clarity on purchase price accounting.

Today, the Board of Directors declared a quarterly cash dividend of $0.05 per share on the Company's $0.01 par value common stock, payable on January 31, 2019, to stockholders of record as of January 15, 2019.

In addition to the dividend payment, the Board approved a share repurchase authorization of up to $50 million through December 31, 2020. Shares may be repurchased in the open market or through private transactions at times and amounts determined by the Company based on its evaluation of market conditions and other factors.

Antonio Carrillo, President and Chief Executive Officer, commented, "We are excited to announce the completion of the ACG Materials acquisition while also putting in place the additional key elements of our growth-oriented capital allocation strategy. Arcosa's strong liquidity position, together with our considerable free cash flow generation, provides us the flexibility to invest in organic projects and bolt-on acquisitions at ACG Materials and our other businesses, while also enhancing shareholder returns through dividends and share repurchases. We remain focused on improving return on invested capital to create shareholder value."

Reconciliation of Adjusted EBITDA for ACG Materials ("ACG")
(in millions)
(unaudited)

"Adjusted EBITDA" is defined as ACG's net income plus interest expense, income taxes, depreciation and amortization, and other one-time or non-recurring expenses, including management fees, debt refinancing fees, and non-recurring professional fees. Adjusted EBITDA is not a calculation based on generally accepted accounting principles. The amounts included in the Adjusted EBITDA calculation, however, are derived from amounts included in the historical statements of operations data. In addition, Adjusted EBITDA should not be considered as an alternative to net income or operating income as an indicator of ACG's operating performance, or as an alternative to operating cash flows as a measure of liquidity. We believe Adjusted EBITDA assists investors in comparing a company's performance on a consistent basis without regard to depreciation and amortization and other expenses, which can vary significantly depending upon many factors.
