Q1 FY2023 EARNINGS PRESENTATION In addition to reporting financial results in accordance with Generally Accepted Accounting Principles in the United States ("GAAP"), AZZ has provided EBITDA and Adjusted EBITDA, which are non-GAAP measures. Management believes that the presentation of these measures provides investors with a greater transparency comparison of operating results across a broad spectrum of companies, which provides a more complete understanding of AZZ’s financial performance given the influx of merger and acquisition and divestiture activities, competitive position and prospects for the future. Management also believes that investors regularly rely on non-GAAP financial measures, such as EBITDA and Adjusted EBITDA, to assess operating performance and that such measures may highlight trends in the Company’s business that may not otherwise be apparent when relying on financial measures calculated in accordance with GAAP.
