In November 2022, the Company completed the acquisition of Purigen Biosystems, Inc. for approximately $32.0 million in cash and up to an aggregate of $32.0 million in cash payable based on the achievement of certain milestones. Cash of $1.2 million will be held in an escrow fund for purposes of satisfying any post-closing purchase price adjustments and indemnification claims under the Purigen Merger Agreement.

The purchase price allocation for the acquisition of Purigen is preliminary and subject to revision as additional information about the fair value of assets and liabilities becomes available. As permitted under ASC 805, the Company is allowed a measurement period, which may not exceed one year, in which to complete its accounting for the acquisition. Per the terms of the Purigen Merger Agreement, the purchase price is still subject to adjustment for the final determination of deferred and current tax assets and liabilities. During the second quarter of 2023, the Company recorded an increase in the estimated return of cash to buyer from escrow in the amount of $5,000, with the offset recorded to goodwill.

The total purchase price was allocated to Purigen’s tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, with the excess recorded as goodwill, as follows:


Cash & cash equivalents	$	290,000
Accounts receivable	259,000
Inventory	944,000
Prepaid expenses and other current assets	184,000
Property and equipment, net	805,000
Restricted cash	400,000
Operating lease right-of-use assets	1,636,000
Other long-term assets	533,000
Intangible assets	20,000,000
Goodwill	22,646,000
Accounts payable and other accrued liabilities	(1,152,000)
Operating lease liability (short-term and long-term)	(1,636,000)
Net assets acquired	$	44,909,000

The Company uses the income approach to derive the fair value of the identified intangible assets acquired. This approach calculates fair value by estimating future cash flows attributable to the assets and then discounting these cash flows to a present value using a risk-adjusted discount rate.

The customer relationships and trade name intangibles are being amortized on a straight-line basis over their estimated useful lives of 5 years. The developed technology intangible is being amortized on a straight-line basis over its estimated useful live of 15 years. Straight-line amortization was determined to be materially consistent with the pattern of expected use of the intangible assets.

As the Company began integrating Purigen’s operations with its existing operations during the fourth quarter of 2022, it is not practical or meaningful to distinguish Purigen’s expenses or net income or loss from that of the combined operations.

The unaudited pro forma financial information in the table below summarizes the combined results of operations for the Company and Purigen as if the companies had been combined as of the beginning of the year prior to the acquisition. These amounts have been calculated after applying the Company’s accounting policies and adjusting the results of Purigen to reflect the additional amortization that would have been charged assuming the fair value adjustments to intangible assets had been applied at the beginning of the year prior to the acquisition. The following unaudited pro forma financial information is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved as if the acquisition had taken place as of January 1, 2021.
