2. | Acquisitions
On December 17, 2021, our subsidiary, EnPro Holdings, Inc. ("EnPro Holdings"), completed the acquisition of all issued and outstanding membership interests of TCFII NxEdge LLC (“NxEdge”). Based in Boise, Idaho, NxEdge serves customers across the semiconductor supply chain, including top tier global integrated device manufacturers and original equipment manufacturers from six main facilities located in Idaho and California. With vertically integrated capabilities across the semiconductor value chain, including a robust aftermarket business, NxEdge is a leading supplier offering a set of integrated capabilities with unique processes resulting in a broad range of qualifications at top customers. NxEdge is included in our Advanced Surface Technologies segment. The acquisition was paid for with $853.9 million in cash, net of cash acquired. We funded the payment with available cash on hand, borrowings under our revolving credit facility and borrowings under new term loan facilities. Additionally, there were $15.0 million of acquisition-related costs recorded during the year ended December 31, 2021, which were expensed when incurred and included in selling, general and administrative expense in the accompanying Consolidated Statement of Operations for the year then ended. On October 26, 2020, a subsidiary of Enpro formed for this purpose (the "Alluxa Acquisition Subsidiary") acquired all of the equity securities of Alluxa, Inc. ("Alluxa"), a privately held, California-based company. Alluxa is an industrial technology company that provides specialized optical filters and thin-film coatings for the most challenging applications in the industrial technology, life sciences, and semiconductor markets. Alluxa's products are developed through a proprietary coating process using state-of-the-art advanced equipment. Alluxa is included in our Advanced Surface Technologies segment. Alluxa works in collaboration with customers across major end markets to provide customized, complex precision coating solutions through its specialized technology platform and proprietary processes. Alluxa has cultivated long-standing customer relationships across its diversified customer base. Alluxa’s global distribution capabilities support the company’s international reach, serving customers across the Americas, Europe, and Asia. Founded in 2007, Alluxa has two locations in California and is headquartered in Santa Rosa, California. In connection with the completion of the transaction, we entered into a limited liability operating agreement (the “Alluxa LLC Agreement”) with respect to the “Alluxa Acquisition Subsidiary” in connection with the rollover transaction with the Alluxa Executives receiving approximately 7% of the equity interests of the Alluxa Acquisition Subsidiary in return for their contribution of the rollover shares of Alluxa. Pursuant to the Alluxa LLC Agreement, each Alluxa Executive has the right to sell to us, and we have the right to purchase from each Alluxa Executive (collectively, the “Put and Call Rights”), one-third of the Alluxa Executive equity interests in the Alluxa Acquisition Subsidiary during each of three exercise periods in 2024, 2025 and 2026, with any amount not sold or purchased in a prior exercise period being carried forward to the subsequent exercise periods (although for one Alluxa Executive who transitioned to a consulting role on January 1, 2023, the full amount of his equity interests are subject to the Company’s right to purchase on June 30, 2024, with two-thirds of the equity interests purchasable at the fixed value of the equity interests as set forth in the Alluxa LLC Agreement). The Alluxa LLC Agreement also provides for the purchase by us of all of an Alluxa Executive's equity interests in the Alluxa Acquisition Subsidiary in connection with the termination of employment of the Alluxa Executive under specified circumstances, with payments in certain circumstances to be made in annual installments. In certain cases involving the termination of an Alluxa Executive's employment, the consideration payable to an Alluxa Executive for the purchase of his equity interests is equal to the fixed value set forth in the Alluxa LLC Agreement (an aggregate of $17.85 million for all of the Alluxa Executives). In all other cases, including upon any exercise of the Alluxa Put and Call Rights, the consideration payable under the Alluxa LLC Agreement in connection with any such purchase by us of an Alluxa Executive's equity interests in the Alluxa Acquisition Subsidiary is equal to the greater of the fixed value of the equity interests as set forth in the Alluxa LLC Agreement or a price based upon a multiple of twelve-month adjusted EBITDA based upon certain financial metrics of the Alluxa Acquisition Subsidiary, plus cash and less indebtedness of the Alluxa Acquisition Subsidiary prior to the relevant payment, and subject to certain adjustments dependent upon the circumstances of the purchase and sale. On September 25, 2019, we acquired all of the equity securities of LeanTeq Co., Ltd. and its affiliate LeanTeq LLC (collectively referred to as “LeanTeq”). LeanTeq primarily provides refurbishment services for critical components and assemblies used in state-of-the-art semiconductor equipment. This equipment is used to produce the latest and most technologically advanced microchips for smartphones, autonomous vehicles, high-speed wireless connectivity, artificial intelligence, and other leading-edge applications. Founded in 2011 and headquartered in Taoyuan City, Taiwan, LeanTeq has two locations in Taiwan and one in the United States (Silicon Valley). LeanTeq is included within the Advanced Surface Technologies segment. A limited liability company agreement (the "LeanTeq LLC Agreement") entered into with respect to Lunar as part of the LeanTeq acquisition, provided Enpro with the right to buy from each LeanTeq Executive (each a LeanTeq "Call Option”), and each LeanTeq Executive with the right to sell to Enpro (the "Put Option") such LeanTeq Executive's Rollover Equity as follows: Enpro had the right to buy, and the LeanTeq Executive had the right to sell, such Rollover Equity within 90 days following the third anniversary of the closing and payable in two installments as follows (the "Put/Call Price"): •Half of the price payable for the Rollover Equity is to be equal to a pro rata portion of a multiple of EBITDA (as defined) of Lunar (on a consolidated basis) during the last 12 months (“LTM”) ending on the closest month end prior to the last month end before the purchase or sale (the "First Measurement Date") less Lunar's consolidated net debt in excess of cash as of the First Measurement Date (the "First Exercise Price"). The applicable multiple depends on the future LTM EBITDA margin and revenue growth; •The remaining half of the price payable for the Rollover Equity is to be equal to an amount that is the higher of the First Exercise Price and a pro rata portion of a multiple of EBITDA of Lunar (on a consolidated basis) during the LTM prior to the first anniversary of the First Measurement Date (the "Second Measurement Date") less Lunar's consolidated net debt in excess of cash as of the Second Measurement Date. The applicable multiple depends on the future LTM EBITDA margin and revenue growth. •During the fourth quarter of 2022, Enpro acquired all the equity securities of Lunar owned by the LeanTeq Executives and became the sole owner of LeanTeq. As a result of this purchase transaction, $35.0 million of our Redeemable Non-Controlling Interests was reclassified as a liability. We entered into a subsequent agreement with the LeanTeq Executives where we agreed to pay the full Put/Call Price calculated at the First Measurement Date and paid $41.9 million in December 2022, which was the minimum purchase price for these equity securities, of which $7.8 million eliminated our outstanding deferred compensation liability and $34.1 million reduced the liability attributable to the redeemable non-controlling interest acquisition. We anticipate an additional $1.1 million payment in the first quarter of 2024 based on Put/Call Price determined at the Second Measurement Date, which was subject to the financial performance of LeanTeq through November 2023. We have recorded this anticipated $1.1 million payment as a liability included in accrued expenses on our consolidated balance sheet as of December 31, 2023. The fair value of the Alluxa Executives' equity interests and the LeanTeq Executives' Rollover Equity was estimated as of the closing date of those transactions. Due to the presence of the put arrangements and thus that redemption is not solely within our control, the Alluxa Executives' equity interests are, and, prior to December 2022, the LeanTeq Executives' Rollover Equity had been, presented as redeemable non-controlling interests. We initially recognized the amount at fair value, inclusive of the put-call provisions. We adjust the redeemable non-controlling interests when the redemption value exceeds the carrying value with changes recognized as an adjustment to equity. Sales of $8.6 million and a pre-tax loss of $1.9 million for NxEdge are included in our Consolidated Statement of Operations for the year ended December 31, 2021. The following unaudited pro forma condensed consolidated financial results of operations for the years ended December 31, 2022 and 2021 are presented as if these acquisitions had been completed before January 1, 2021:
| 2022 |  | 2021
Pro forma net sales | $ | 1,099.2 |  |  | $ | 1,016.8 |
Pro forma net income from continuing operations | 16.2 |  |  | 82.1 |
These amounts have been calculated after applying our accounting policies and adjusting the results of NxEdge to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to inventory, property, plant and equipment and intangible assets had been applied prior to January 1, 2021 as well as additional interest expense to reflect financing required, together with the corresponding tax effects. The supplemental pro forma net income for the year ended December 31, 2021 was adjusted to exclude $15.0 million of pre-tax acquisition-related costs. These pro forma financial results have been prepared for comparative purposes only and do not reflect the effect of synergies that would have been expected to result from the integration of these acquisition. The pro forma information does not purport to be indicative of the results of operations that actually would have resulted had the acquisition occurred prior to January 1, 2021, or of future results of the consolidated entities.
