The Transaction was consummated pursuant to the terms and conditions of the Stock Purchase Agreement, dated as of January 30, 2026, between the Company and the Buyer. The Transaction is considered a significant disposition under Regulation S-X Article 11 significance tests, as such the Company is providing pro financial information giving effect to the disposal herein.

The unaudited pro forma condensed consolidated financial statements have been prepared based upon the best available information and management estimates and are subject to assumptions and adjustments described below and in the accompanying notes to those financial statements.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Disposal of Segment

(a) These adjustments reflect the removal of the associated assets, liabilities and operations attributable to the Business, which were included in the Company’s historical financial statements. The historical results of operations, which were removed, include certain corporate overhead and selling, general and administrative costs which were historically allocated to the Business based on estimated use. These allocations included wages and non-wage expenses related to the Company’s corporate support functions and occupancy costs, such as those related to operations, procurement, advanced manufacturing engineering and others.

Transaction Accounting Adjustments

(b) Reflects the expected cash consideration received from the sale of the Business at the close of the Transaction, transaction costs and other items pursuant to the terms of the sale. The final cash amount will be determined subsequent to closing based on the final working capital balance as defined by the Stock Purchase Agreement and finalization of transaction costs. In addition, a receivable was recognized for estimated working capital due to the Company and a payable was recognized for certain transaction related costs. All transaction costs have been excluded from the pro forma condensed consolidated statements of income.


Purchase price	$	59,000

Transaction costs due at close	(5,121)
Total closing cash consideration	53,879
Required repayment of revolving credit facility (e)	(30,000)
Net closing cash consideration	$	23,879

(d) Reflects the net impact of deferred tax assets attributed to the Business.

(e) Reflects the use of closing cash consideration to repay $30.0 million of outstanding debt on the Company’s revolving credit facility, a portion of which was required to be repaid under the terms of our amended and restated credit agreement.

(f) Reflects the estimated pre-tax loss on the sale of the Business and the effect on total equity of the adjustments described in notes (b) through (e) above.

(g) In connection with the sale, the Company and Buyer have entered into manufacturing, employee leasing and transition services agreements at closing whereby both the Company and the Buyer will provide certain post-close services on a transitional basis. The estimated impacts of these agreements have been reflected within the unaudited pro forma condensed consolidated statements of income, depending on the nature of the services provided. These agreements have various terms of 4 - 36 months following the close of the Transaction.

(h) Reflects an adjustment to record the impact to net sales and cost of goods sold of trade sales previously eliminated as intercompany sales. Eliminations were based on actual historical intercompany sales.

(i) Reflects a reduction of interest expense incurred in connection with the repayment of $30.0 million of outstanding debt outlined in footnote (e). Interest expense was calculated using the weighted average interest rates of our revolving credit facility for the periods presented.

(j) Reflects the tax impact of pro forma adjustments relating to the removal of the Business, as well as the estimated tax impact attributable to the various manufacturing and transition service agreements provided by and on the behalf of the Company. This adjustment was determined by applying the relevant statutory tax rates to the jurisdictional mix of income of these adjustments. This transaction accounting adjustment also reflects the impact of deferred tax asset and liability reversals.

(k) The estimated pre-tax loss on the sale of the Business, as reflected in the condensed consolidated statement of income for the year ended December 31, 2024, is calculated as follows:


Total closing cash consideration (b)	$	53,879
Net assets of the Business	(90,991)
Estimated working capital adjustment	6,375
Transaction accounting adjustments	(7,326)
Pre-tax loss on sale of business	$	(38,063)
