Schedule of Fair Values of the Assets Acquired and Liabilities Assumed

Preliminary Allocation of Consideration Transferred to Net Assets Acquired

The following table presents the preliminary determination of the fair values of identifiable assets acquired and liabilities assumed from the Company's 2026 acquisition of NSI Industries (in millions).

The final determination of the fair value of certain assets and liabilities will be completed within the applicable one year measurement period as required by FASB ASC Topic 805, “Business Combinations.” As the Company finalizes the fair values of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period.

Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations and financial position. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company's results of operations and financial position.

Preliminary Allocation of Consideration Transferred to Net Assets Acquired

The following table presents the preliminary determination of the fair values of identifiable assets acquired and liabilities assumed from the Company's 2025 acquisitions of Ventev, Nicor and DMC Power (in millions).

The final determination of the fair value of certain assets and liabilities will be completed within the applicable one year measurement period as required by FASB ASC Topic 805, “Business Combinations.” As the Company finalizes the fair values of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period. The purchase accounting for the Ventev and Nicor acquisitions has been finalized.

Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations and financial position. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company's results of operations and financial position.

Accounts receivable	$	32.1
Inventories	44.4
Other current assets	1.9
Property, plant and equipment	48.7
Other non-current assets	5.4
Intangible assets	417.1
Accounts payable	(12.9)
Other accrued liabilities	(13.9)
Deferred tax liabilities, net	(101.9)
Other non-current liabilities	(8.2)
Goodwill	543.2
Total Estimate of Consideration Transferred, Net of Cash Acquired	$	955.9

Business Combination, Pro Forma Information, Nonrecurring Adjustment

The following supplemental pro-forma information presents consolidated results as if the acquisition had been completed on January 1, 2025.

The following table summarizes the pro forma adjustments to increase or (decrease) reported results to arrive at the pro-forma results.
