NON-GAAP FINANCIAL MEASURES. This Form 10-Q includes certain financial measures that are not calculated and presented in accordance with GAAP. Non-GAAP financial measures typically exclude items that management believes are not reflective of our ongoing operations, and thus should not be included when evaluating our performance. Management uses these non-GAAP financial measures to evaluate ongoing performance, engage in financial and operational planning, and determine incentive compensation. Management believes these non-GAAP financial measures provide useful supplemental information regarding the performance of our ongoing operations and should not be considered as an alternative to the comparable GAAP financial measure. Additionally, management believes these non-GAAP financial measures allow for meaningful comparisons and analysis of trends in our business and enable investors to evaluate our operations and future prospects in the same manner as management.

Beginning in the third quarter of fiscal 2026, we updated our definition of adjusted operating income, adjusted net earnings, adjusted EBITDA, and adjusted EPS – diluted to exclude the acquisition-related amortization of inventory step-up charges. Non-GAAP financial measures for prior periods presented in this Form 10-Q have been recast for comparability.

The following provides an explanation of each non-GAAP financial measure presented in this Form 10-Q:

Adjusted operating income (loss)is defined as operating income (loss) excluding the items listed below, to the extent naturally included in operating income (loss).

Adjusted net earnings is defined as net earnings attributable to controlling interest excluding the after-tax effect of the excluded items outlined below.

Adjusted EPS - dilutedis defined as adjusted net earnings divided by diluted weighted-average common shares outstanding for the applicable period.

Adjusted EBITDAis the measure by which management evaluates segment performance and overall profitability. Adjusted EBITDA excludes additional items including, but not limited to, those listed below, as well as other items that management believes are not reflective of, and thus should not be included when evaluating the performance of ongoing operations. Adjusted EBITDA also excludes stock-based compensation due to its non-cash nature, which is consistent with how management assesses operating performance and determines incentive compensation. At the segment level, adjusted EBITDA includes expense allocations for centralized corporate back-office functions that exist to support the day-to-day business operations. Public company and other governance costs are held at the corporate level within the unallocated corporate and other category.

Adjusted EBITDA margin is calculated by dividing adjusted EBITDA by net sales.

EXCLUSIONS FROM NON-GAAP FINANCIAL MEASURES

Management believes it is useful to exclude the following items from its non-GAAP financial measures for its own and investors’ assessment of the business for the reasons identified below. Additionally, management may exclude other items from non-GAAP financial measures that do not occur in the ordinary course of our ongoing business operations and note them in the reconciliation from net earnings to the non-GAAP financial measure adjusted EBITDA.

•

Amortization of inventory step-uprepresents the increase in inventory fair value associated with our acquisitions. The increase in inventory fair value is amortized to cost of sales over the period that the related inventory is sold. The amortization of inventory step-up is excluded because it is a non-cash expense that is not indicative of ongoing operating results.

•

Impairment chargesare excluded because they do not occur in the ordinary course of our ongoing business operations, are inherently unpredictable in timing and amount, and are non-cash, which management believes facilitates the comparison of historical, current and forecasted financial results.

•

Restructuring and other expense, netconsist of established programs that are intended to fundamentally change our operations, and as such are excluded from our non-GAAP financial measures. Our restructuring programs may include closing or consolidating production facilities or moving manufacturing of a product to another location, realignment of the management structure of a business unit in response to changing market conditions or general rationalization of headcount. Our restructuring activities generally give rise to employee-related costs, such as severance pay, and facility-related costs, such as exit costs and gains or losses on asset disposals but may include other incremental costs associated with our restructuring activities. Restructuring and other expense, net, may also include other nonrecurring items included in operating income but incremental to our normal business activities. These items are excluded because they are not indicative of the ongoing operations of our underlying business.

•

Loss on partial sale of investment in SES, which resulted from the divestiture of our 49% interest in the Composites business of the SES joint venture, is excluded because it did not occur in the normal course of business.

•

Unrealized loss on investment in marketable equity securities represents the net impact of unrealized losses resulting from mark-to-market adjustments on our marketable equity securities. We exclude this activity because it is not reflective of on-going operating activity and does not provide a meaningful evaluation of operating performance.

Consolidated Results – Selected Non-GAAP Adjusted Results

Consolidated Results - Adjusted EBITDA

(1)

Excludes the impact of noncontrolling interest.

(2)

Reflects the amortization of the step-up to fair market value of acquired inventory related to the LSI and Elgen acquisitions in fiscal 2026 and the Ragasco acquisition in fiscal 2025. We updated the definition of our non-GAAP financial measures to exclude inventory step-up charges in the third quarter of fiscal 2026. All previously reported amounts in this Form 10-Q have been recast to conform to this change.

(3)

Reflects the loss incurred in connection with divestment of our 49% interest in the composite assets of our SES joint venture on October 16, 2025. In exchange for our interest in the divested assets, we received common shares of both Hexagon Composites and Hexagon Purus.

(4)

Reflects the unrealized loss associated with the marketable securities noted in footnote (3) above.

(5)

EBIT and adjusted EBIT are non-GAAP financial measures. However, these measures are not used by management to evaluate our performance, engage in financial and operational planning, or to determine incentive compensation. Instead, they are included as subtotals in the reconciliation of net earnings to adjusted EBITDA, which is a non-GAAP financial measure used by management.

(6)

Excludes $2.7 million of stock-based compensation reported in restructuring and other expense, net in the consolidated statement of earnings for the prior year period related to the accelerated vesting of certain outstanding equity awards upon retirement of a key employee.
