On March 4, 2025, the Company completed its acquisition of 908 Devices Inc.’s (“908 Devices”) desktop portfolio of four devices for bioprocessing process analytical technology applications (“PAT Portfolio”). In connection with the transaction, Repligen also acquired facilities, employees, equipment and lease obligations for facilities in North Carolina and Braunschweig,

Germany as well as certain working capital balances related to the PAT Portfolio. This transaction is referred to as the 908 Devices PAT Portfolio acquisition.

The Company accounted for the 908 Devices PAT Portfolio acquisition as a purchase of a business under Accounting Standards Codification (“ASC”) 805, “Business Combinations.” Under the securities and asset purchase agreement, the PAT portfolio and associated net assets were acquired for cash consideration of $69.9 million, subject to a working capital adjustment to be finalized in a future period. Under the acquisition method of accounting, the assets acquired and liabilities assumed were recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company. The provisional fair value of the net tangible assets acquired is estimated to be $6.2 million, the provisional fair value of intangible assets acquired is estimated to be $13.6 million and the residual provisional goodwill is estimated to be $50.1 million. Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which such costs are incurred. The Company has incurred $8.4 million of transaction and integration costs associated with the 908 Devices PAT Portfolio acquisition from the date of acquisition to June 30, 2025. The transaction and integration costs are included in operating expenses in the condensed consolidated statements of comprehensive income.

The preliminary allocation of purchase price is based on the fair value of assets acquired and liabilities assumed as of the acquisition date. As of June 30, 2025, the purchase accounting for this acquisition had not been finalized and has been recorded on a provisional basis. As additional information becomes available, including but not limited to the outcome of an updated valuation related to developed technology and additional analysis related to inventory valuation, the Company may further revise its preliminary purchase price allocation during the remainder of the measurement period. Amounts recorded on a provisional basis include but are not limited to intangible assets, working capital accounts including inventories, deferred tax accounts, deferred revenues, lease assets and goodwill. The components and estimated allocation of the purchase price consist of the following (amounts in thousands):


Cash and cash equivalents	$	191
Accounts receivable		1,110
Inventory		6,946
Prepaid expenses and other current assets		535
Property and equipment		1,698
Operating lease right of use assets		2,552
Other assets, long-term		41
Customer relationships		5,040

During the quarter ended June 30, 2025 measurement period adjustments resulted in a net decrease to provisional goodwill in the amount of $77 thousand, and reflect adjustments made to certain asset and liability accounts including inventories, intangible assets, leases and deferred taxes, as management continues to finalize the identification and measurement of acquired assets and assumed liabilities.

The measurement period adjustments described above, had they been reflected in the Company’s initial accounting for the 908 Devices PAT Portfolio acquisition would not have resulted in any material differences between what the Company recorded in its condensed consolidated statements of comprehensive income for the quarter ended March 31, 2025.

The goodwill of $50.1 million (determined on a provisional basis and thus subject to change during the measurement period) represents future economic benefits expected to arise from anticipated synergies from the integration of the PAT Portfolio into the Company. These synergies include operating efficiencies and strategic benefits projected to be achieved as a result of the 908 Devices PAT Portfolio acquisition. Goodwill is calculated based on the acquired assets in the United States and Germany. Goodwill related to the United States of $39.2 million is deductible for income tax purposes. The goodwill of $10.9 million related to Germany is expected to be nondeductible for income tax purposes.

The following table sets forth the components of the identified intangible assets (determined on a provisional basis and thus subject to change during the measurement period) associated with the 908 Devices PAT Portfolio acquisition and their estimated useful lives:


	Useful life	Fair Value
		(Amounts in thousands)
Customer relationships	8 - 9 years	$	5,040
Developed technology	10 - 12 years		6,910
Trademark and tradename	13 - 14 years		1,660

During the quarter ended June 30, 2025 measurement period adjustments resulted in a net decrease to provisional goodwill in the amount of $162 thousand, as a result of a working capital payment made as required by the Share Swap Agreement offset by a deferred tax liability adjustment.

The goodwill of $46.9 million (determined on a provisional basis and thus subject to change during the measurement period) represents future economic benefits expected to arise from anticipated synergies from the integration of Tantti into the Company. These synergies include operating efficiencies and strategic benefits projected to be achieved as a result of the Tantti Acquisition. Substantially all of the goodwill recorded is expected to be nondeductible for income tax purposes.

The identified intangible asset (determined on a provisional basis and thus subject to change during the measurement period) associated with the Tantti Acquisition is developed technology of $28.9 million with a useful life of nine years.
