It provides entry into the complementary steel and concrete lighting pole market while expanding our product offerings in traffic and telecom. The acquisition bolsters our Engineered Structures segment and increases our exposure to growing infrastructure end markets at an attractive valuation. We look forward to welcoming the Ameron team to Arcosa and combining our strengths to accelerate growth.”

Reconciliation of Ameron Pro Forma Adjusted EBITDA

(in millions)

(unaudited)

“EBITDA” is defined as net income plus interest, taxes, depreciation, depletion, and amortization. “Pro-Forma Adjusted EBITDA” is defined as Ameron's EBITDA plus pro forma adjustments for non-recurring items. GAAP does not define Pro-Forma Adjusted EBITDA and it should not be considered as an alternative to earnings measures defined by GAAP, including net income. We believe Pro-Forma Adjusted EBITDA assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items which can vary significantly depending on many factors.

NON-GAAP MEASURES Refer to slides that follow for accompanying reconciliations “EBITDA” is defined as net income plus interest, taxes, depreciation, depletion, and amortization. “Adjusted EBITDA” is defined as EBITDA adjusted for certain items that are not reflective of the normal earnings of our business. GAAP does not define EBITDA or Adjusted EBITDA and they should not be considered as alternatives to earnings measures defined by GAAP, including net income. We use Adjusted EBITDA to assess the operating performance of our consolidated business, as a metric for incentive-based compensation, as a measure within our lending arrangements, and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value. As a widely used metric by analysts, investors, and competitors in our industry, we believe Adjusted EBITDA also assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items which can vary significantly depending on many factors. “Adjusted EBITDA Margin” is defined as Adjusted EBITDA divided by Revenues. GAAP does not define “Adjusted Net Income” and it should not be considered as an alternative to earnings measures defined by GAAP, including net income. We use this metric to assess the operating performance of our consolidated business. We adjust net income for certain items that are not reflective of the normal operations of our business to provide investors with what we believe is a more consistent comparison of earnings performance from period to period. “Segment EBITDA” is defined as segment operating profit plus depreciation, depletion, and amortization. “Adjusted Segment EBITDA” is defined as Segment EBITDA adjusted for certain items that are not reflective of the normal earnings of our business. GAAP does not define Segment EBITDA or Adjusted Segment EBITDA and they should not be considered as alternatives to earnings measures defined by GAAP, including segment operating profit. We use Adjusted Segment EBITDA to assess the operating performance of our businesses, as a metric for incentive-based compensation, and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value. As a widely used metric by analysts, investors, and competitors in our industry we believe Adjusted Segment EBITDA also assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items, which can vary significantly depending on many factors. “Adjusted Segment EBITDA Margin” is defined as Adjusted Segment EBITDA divided by Revenues. GAAP does not define “Net Debt” and it should not be considered as an alternative to cash flow or liquidity measures defined by GAAP. The Company uses Net Debt, which it defines as total debt minus cash and cash equivalents to determine the extent to which the Company’s outstanding debt obligations would be satisfied by its cash and cash equivalents on hand. The Company also uses “Net Debt to Adjusted EBITDA”, which it defines as Net Debt divided by Adjusted EBITDA for the trailing twelve months as a metric of its current leverage position. We present this metric for the convenience of investors who use such metrics in their analysis and for shareholders who need to understand the metrics we use to assess performance and monitor our cash and liquidity positions. GAAP does not define “Free Cash Flow” and it should not be considered as an alternative to cash flow measures defined by GAAP, including cash flow from operating activities. We define Free Cash Flow as cash provided by operating activities less “Net Capital Expenditures”, which is defined as capital expenditures net of the proceeds from the disposition of property, plant, equipment, and other assets. We use this metric to assess the liquidity of our consolidated business. We present this metric for the convenience of investors who use such metrics in their analysis and for shareholders who need to understand the metrics we use to assess performance and monitor our cash and liquidity positions. “Ameron Pro Forma Adjusted EBITDA” is defined as Ameron's EBITDA plus pro forma adjustments for non-recurring items. GAAP does not define Pro-Forma Adjusted EBITDA and it should not be considered as an alternative to earnings measures defined by GAAP, including net income. We believe Pro-Forma Adjusted EBITDA assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items which can vary significantly depending on many factors. 30 I MOVING INFRASTRUCTURE FORWARD I 2024
