Non-GAAP Reconciliation Continued (a) The presentation includes a
reconciliation of Income Before Income Taxes, a measure defined by Generally Accepted Accounting Principles in the United States (GAAP), to EBIT, Adjusted EBIT and Adjusted EBITDA. (b) EBIT is defined as earnings (loss) before interest and taxes,
with Adjusted EBIT provided for the purpose of adjusting for items impacting earnings that are not considered by management to be indicative of ongoing operations. We evaluate the profit performance of our segments based on income before income
taxes, but also look to EBIT, or adjusted EBIT, as a performance evaluation measure because Interest expense and Investment (expense) income, net are essentially related to corporate functions, as opposed to segment operations. For that reason, we
believe EBIT is also useful to investors as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, income before income taxes as determined in accordance with GAAP, since EBIT omits the
impact of interest and investment income or expense in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness. Nonetheless, EBIT is a key measure expected by and useful to our
fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets' analysis of our segments' core operating performance. We also evaluate EBIT because it is
clear that movements in EBIT impact our ability to attract financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results. (c) Reflects restructuring and other charges, which
have been incurred in relation to our Margin Acceleration Plan ( MAP to Growth ), Margin Achievement Plan ( MAP 2025 ) and our 2026 restructuring action, together MAP Initiatives, as follows: - Restructuring and other related expense, net: Includes
charges incurred associated with our MAP to Growth and MAP 2025 programs related to headcount reductions, facility closures and impairments recorded in Restructuring Expense on the Consolidated Statements of Income. Restructuring Expense related to
these programs totaled $6.3 million, $15.5 million, $30.0 million, $25.0 million and $18.2 million for fiscal years 2022, 2023, 2024, 2025 and 2026 respectively. Other related expenses include inventory write-offs in connection with restructuring
activities recorded in Cost of Sales and accelerated depreciation and amortization recorded within Cost of Sales or Selling, General, & Administrative Expenses ( SG&A ) depending on the nature of the expense. Fiscal 2024 also had an increase
in our allowance for doubtful accounts resulting from the divestiture of the non-core Universal Sealants Bridgecare services business. - 2026 Restructuring and other related expense, net: Includes charges incurred related to headcount reductions and
facility closures associated with the SG&A-focused optimization actions and other early stage MAP 2030 actions recorded in Restructuring Expense on the Consolidated Statements of Income. Restructuring Expense related to the 2026 restructuring
action totaled $24.4 million for the 2026 fiscal year. Other related expenses consist of higher executive departure costs, including accelerated stock compensation expense, that do not qualify as restructuring expense and are recorded within
SG&A as well as accelerated depreciation recorded within Cost of Sales or “Selling, General, & Administrative Expenses depending on the nature of the expense. Other related expenses also includes inventory write-offs in connection with
restructuring activities recorded in Cost of Sales . - Exited product lines: Mainly related to prepaid asset and inventory write-offs from the discontinuation of certain product lines which resulted from product line rationalization efforts in
connection with our MAP Initiatives and recorded in Cost of Sales . - ERP consolidation plan: Includes expenses incurred as a result of our stated goals to consolidate over 75 ERP systems across the organization to one ERP platform per segment, as
part of our overall MAP strategy as well as costs incurred for other decision support tools to facilitate our commercial initiatives related to MAP 2025 which have been incurred in all segments, as well as Corporate/Other, and have been recorded
within SG&A . - Professional fees: Includes expenses incurred to consolidate accounting locations, costs incurred to implement technologies and processes to drive improved data analytics/decision making and cost incurred to implement new global
manufacturing methodologies with the goal of improving operating efficiency incurred within all of our segments as well as Corporate/Other and recorded within SG&A . All of this spend is in support of stated MAP goals with the most significant
expense incurred within Corporate/Other. - Goodwill Impairment: Relates to an impairment charge at our Universal Sealants ( USL ) reporting unit as a result of a decision to exit the services portion of that business which has been recorded in
Goodwill Impairment in the third quarter of fiscal 2023. - (Gain) loss on sale of closed facilities, net: Net gain recognized related to the sale of certain properties which were closed as part of the MAP Initiatives. Included below is a
reconciliation of the TOTAL CONSOLIDATED MAP initiatives. Investor Day | November 9, 2026 48

defined as earnings (loss) before interest, taxes, depreciation and amortization adjusted for items impacting earnings that are not considered by management to be indicative of ongoing operations. We evaluate the profit performance of our segments
based on income before income taxes, but also look to adjusted EBITDA, as a performance evaluation measure because Interest Expense and investment (Expense) Income, Net are essentially related to corporate functions, as opposed to segment
operations. Additionally, Adjusted EBITDA is an operating measure that provides investors with a measure of operating results unaffected by differences in capital structures, capital investment cycles and ages of related assets among otherwise
comparable companies. For these reasons, we believe Adjusted EBITDA is also useful to investors as a metric in their investment decisions. The reader is cautioned that the Company's Adjusted EBITDA should not be compared to other entities
unknowingly. Adjusted EBITDA should not be considered an alternative to, or more meaningful than, income before income taxes as determined in accordance with GAAP. Investor Day | November 9, 2026 50
