GAAP to NON-GAAP RECONCILIATIONS   With regard to our long-term financial goals, the Company is not providing a quantitative reconciliation for forward looking organic growth, operating income margin, adjusted EBITDA, net debt and free cash flow. The most directly comparable GAAP measures cannot be reliably predicted or estimated without unreasonable effort due to their dependence on future uncertainties, such as the adjustment for items as listed below. Additionally, information about other adjusting items that is currently not available to the Company could have a potentially unpredictable and potentially significant impact on its future GAAP financial results.   Organic sales in this presentation is calculated as net sales excluding the impact of foreign currency translation. Organic sales can be expressed as a dollar amount or a percentage rate when describing organic growth.   Non-GAAP Net Income and Non-GAAP Income From Operations exclude acquisition related amortization expense, acquisition related expense, acquisition related stock compensation expense, restructuring and consolidation costs, non-cash amortization of interest rate swap expense and other income or charges that management does not consider to be directly related to the Company’s core operating performance.   Non-GAAP operating income margin is calculated by dividing Non-GAAP income from operations by GAAP net sales. Non-GAAP adjusted EBITDA represents earnings before interest, taxes, depreciation, acquisition related amortization, acquisition related costs, restructuring costs, stock-based compensation, asset impairment and other income or charges that management does not consider to be directly related to the Company’s core operating performance.    Non-GAAP Free Cash Flow is calculated by deducting purchases of property, plant and equipment.    Non-GAAP Adjusted Free Cash Flow is calculated by adding back the payment for the interest rate swap settlement to Non-GAAP Free Cash Flow.    Net Debt is calculated by subtracting cash and cash equivalents from total gross debt. Non-GAAP Operating Working Capital is calculated by deducting accounts payable from net trade receivables plus inventories.

Appendix Non-GAAP Measures *Based upon management's estimate of acquired entities’ financial results for the years presented. The acquired entities’ pre-acquisition actual historical results have not been subject to an audit and cannot be verified at this point in time. Moreover, the non-GAAP adjusted EBITDA of the acquired entities in the year of acquisition cannot be reconciled to the corresponding audited GAAP measure because no such measure is available to management. Nonetheless, management believes that an estimate of the acquired entities’ Non-GAAP adjusted EBITDA is important to the Company's investors because it provides an estimated indication of the Company's potential ability to service debt and incur additional leverage, if any. *Reconciliation of Non-GAAP Adjusted EBITDA (amount in millions) Year Ended December 31, 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 Net income/(loss) $27.7 $(25.5) $127.2 $35.3 $51.4 $25.1 $35.4 $40.2 $40.3 $24.3 $37.7 $24.5 $(2.3) $6.7 $13.5 $8.9 $2.5 Loss on foreign currency and other, net 1.2 1.7 0.1 0.3 1.0 8.5 1.6 (0.2) 0.9 0.1 1.1 0.7 4.0 (3.4) 1.0 1.1 (0.1) Impairment charges 142.4 147.5 - - - - - - - - - - - 31.8 - - - Automation and Specialty acquisition purchase price adjustment - (0.8) - - - - - - - - - - - - - - - Tax (benefit)/expense (19.9) 29.5 21.0 16.4 19.7 8.7 15.7 22.9 19.2 10.2 10.8 10.0 (2.4) 16.7 8.2 5.8 3.3 Interest expense 94.5 72.1 73.8 28.6 7.7 11.7 12.2 12.0 10.6 40.8 24.0 19.6 33.0 28.3 38.6 25.5 19.5 Depreciation expense 51.9 57.8 58.0 34.8 26.5 21.6 21.6 23.1 21.4 20.5 18.4 15.0 16.5 15.4 16.4 10.8 8.6 Acquisition related amortization expense 70.4 69.8 70.4 25.2 9.5 8.3 8.6 9.0 6.5 6.8 6.3 5.0 5.5 5.7 5.5 3.8 3.0 Bridge fee on TB Woods acquisition - - - - - - - - - - - - - - 0.3 - - Loss on write-off of deferred financing costs - - - 1.2 1.8 2.0 - - - - - - - - - - - Acquisition related expenses 1.5 - 0.7 36.2 2.2 2.3 0.8 3.2 2.5 0.5 3.1 0.8 - - 2.7 1.8 - Loss on partial settlement of pension plans - - - 5.1 1.7 - - 0.5 - - - - - - - - - Stock compensation expense 15.7 13.1 13.6 8.1 5.3 4.2 4.0 3.1 3.2 2.7 2.5 2.1 3.3 2.0 2.0 1.9 0.1 Amortization of fair value of inventory - - - 14.2 2.3 - - 2.4 - 0.1 - - - - 0.9 2.3 1.7 IPO related expenses - - - - - - - - - - - - - - - 0.6 - Private equity advisory fees - - - - - - - - - - - - - - - 3.0 - OPEB settlement gain/loss - - - - - - - - - - - - (1.5) (0.9) 2.7 (3.8) - Inventory adjustment due to economic downturn - - - - - - - - - - - - 2.2 - - - - European workers compensation claim - - - - - - - 0.4 0.6 - - - - - - - - Legal Fees associated with pursuit of unfair trade remedy - - - - - 0.7 0.4 - - - - - - - - - - Supplier warranty settlement - - - (2.0) - 2.8 - - - - - - - - - - Restructuring and consolidation expense 3.0 7.4 14.1 4.4 4.2 10.3 7.2 1.8 1.1 3.2 - 2.7 7.3 2.3 2.4 - - Non-GAAP adjusted EBITDA* $388.4 $372.6 $378.9 $207.8 $133.3 $103.4 $110.3 $118.4 $106.3 $109.2 $103.9 $80.4 $65.6 $104.6 $94.2 $61.7 $38.6 Estimated Non-GAAP Adjusted EBITDA for Acquisitions 7.3 - - 197.7 - 21.5 - - 15.6 - 4.7 - - - 4.1 1.6 - Proforma Combined Non-GAAP Adjusted EBITDA* $395.7 $372.6 $378.9 $405.5 $133.3 $124.9 $110.3 $118.4 $121.9 $109.2 $108.6 $80.4 $65.6 $104.6 $98.4 $63.3 $38.6
