On January 17, 2023 (the “Closing Date”), the Company acquired 100% of the issued and outstanding shares of capital stock of Entrepix, Inc., an Arizona corporation (“Entrepix”), which primarily manufactures chemical mechanical polishing (“CMP”) technology, through a reverse triangular merger. Entrepix’s CMP technology portfolio and water cleaning equipment will complement our existing substrate polishing and wet process chemical offerings. Pursuant to the terms and conditions of the Agreement and Plan of Merger dated January 17, 2023 (the “Merger Agreement”), Emerald Merger Sub, Inc., a wholly-owned subsidiary of the Company (“Merger Sub”), merged with and into Entrepix (the “Merger”), resulting in Entrepix surviving the Merger and becoming a wholly-owned subsidiary of the Company (the “Acquisition” or “Transaction”).

On the Closing Date, in connection with the Merger Agreement and in contemplation of the Transaction, the Company entered into a Loan and Security Agreement with UMB Bank, N.A., under which the Lender provided the Company with (i) a $12.0 million term loan maturing January 17, 2028, and (ii) an $8.0 million revolving loan facility maturing January 17, 2024 (see Note 2). The proceeds of the Term Loan were used to partially fund the Transaction.

The Acquisition is accounted for using the acquisition method of accounting for business combinations under FASB Accounting Standard Codification Topic No. 805, Business Combinations (“ASC 805”), with Amtech representing the accounting acquirer under this guidance. The Company elected to apply pushdown accounting per ASC 805-50-50-5.

The total consideration for the Acquisition was $39.2 million, consisting of $35.2 million cash consideration to the sellers and $4.0 million cash paid for debt and Entrepix transaction costs.

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Such assets include synergies the Company expects to achieve, such as deeper penetration into an overlapping customer base, complementary product offerings, and cost redundancy reductions. In accordance with the measurement principles in FASB Accounting Standard Codification Topic No. 820, Fair Value Measurement, the purchase consideration for the Acquisition has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired, including a residual amount of goodwill, none of which is deductible for tax purposes. Amtech’s acquisition costs incurred were $2.5 million for the nine months ended June 30, 2023, and were recorded as “Selling, general and administrative expenses” in the accompanying Condensed Consolidated Statements of Operations. The following table summarizes the provisional fair values assigned to identifiable assets acquired and liabilities assumed, in thousands:

The establishment of the allocation to goodwill requires the extensive use of accounting estimates and management judgement. In accordance with ASC 805, the Company has up to one year from the acquisition date (referred to as the measurement period) to account for changes in the fair values of the identifiable assets acquired and the liabilities

assumed in the acquired entity. As of the issuance of the condensed consolidated financial statements for the period ended June 30, 2023, the Company has not finalized its calculation of deferred tax assets or liabilities, income taxes payable, and the resulting adjustments to goodwill. The tax-related items will be finalized pending a consolidated analysis of the combined tax attributes of the Acquisition. If a change in any of these items is identified during the measurement period, the Company will record the cumulative impact of measurement period adjustments in the period the adjustment is identified. Certain measurement period adjustments were recorded during the quarter ended June 30, 2023, primarily arising from the Company's finalization of the valuation of acquired assets and updated assumptions underlying the tax provision. These adjustments were all offset against goodwill.

The fair value associated with acquired intangible assets and their associated weighted-average amortization periods consist of the following, in thousands:


	Classification of Amortization	Amount		Weighted-Average Amortization Period
Developed technology	Cost of sales	$	6,700	5.0 years
Customer relationships	Selling, general and administrative		2,800	10.0 years
Backlog	Selling, general and administrative		2,100	1.0 year
Trade names	Selling, general and administrative		1,800	10.0 years
Noncompetition agreements	Selling, general and administrative		200	5.0 years
Total intangible assets		$	13,600	6.1 years
