NOTE 2 – ACQUISITION:

On June 1, 2021, the Company completed its acquisition of Barber-Nichols, LLC ("BN"), a privately-owned designer and manufacturer of turbomachinery products located in Arvada, Colorado that serves the defense and aerospace industry as well as the energy and cryogenic markets. The Company believes this acquisition furthers its growth strategy through market and product diversification, broadens its offerings and strengthens its presence in the defense industry, builds on its presence in the energy markets and adds capabilities in the space industry.

This transaction was accounted for as a business combination which requires that assets acquired and liabilities assumed be recognized at their fair value as of the acquisition date. The purchase price of $72,014 was comprised of 610 shares of the Company's

common stock, representing a value of $8,964 at a price of $14.69 per share, and cash consideration of $61,150, subject to certain potential adjustments, including a customary working capital adjustment. The cash consideration was funded through cash on-hand and debt proceeds (See Note 15). The purchase agreement included a contingent earn-out dependent upon certain financial measures of BN post-acquisition, in which the sellers were eligible to receive up to $14,000 in additional cash consideration. At June 30, 2021, a liability of $1,900 was recorded for the contingent earn-out. Subsequent to the acquisition, the earn out agreement was terminated and the contingent liability was reversed into Other operating income, net, on the Company’s Condensed Statement of Operations. Prior to the acquisition, BN and Ascent Properties Group, LLC, a related party, entered into a nine year operating lease agreement for an office and manufacturing building in Arvada, Colorado. This lease was acquired as part of the Company's acquisition of BN and has a monthly payment in the amount of $40 with a 3% yearly escalation. Acquisition related costs of $111 and $373 were expensed in the three and nine month periods ending December 31, 2021, and are included in Selling, general and administrative expenses in the Condensed Consolidated Statement of Operations.

The cost of the acquisition was preliminarily allocated to the assets acquired and liabilities assumed based upon its estimated fair value at the date of the acquisition and the amount exceeding the fair value of $22,923 was recorded as goodwill, which is not deductible for tax purposes. During the second quarter of fiscal 2022, the preliminary valuation of backlog was increased by $100, therefore goodwill was reduced to $22,823. As the values of certain assets and liabilities are preliminary in nature, they are subject to adjustment as additional information is obtained, including, but not limited to, the finalization of the valuation of intangible assets, the final reconciliation and confirmation of tangible assets. The valuation of acquisition-related intangible assets will be finalized within twelve months of the close of the acquisition. The fair value of acquisition-related intangible assets includes customer relationships, technology and technical know-how, backlog and trade name. Backlog and trade name are included in the line item "Other intangible assets, net" in the Condensed Consolidated Balance Sheet. Customer relationships were valued using an income approach, specifically the Multi Period Excess Earnings method, which incorporates assumptions regarding retention rate, new customer growth and customer related costs. Trade name and technology and technical know-how were both valued using a Relief from Royalty method, which develops a market based royalty rate used to reflect the after tax royalty savings attributable to owning the intangible asset. The fair value of backlog was determined using a net realizable value methodology, and was computed as the present value of the expected sales attributable to backlog less the remaining costs to fulfill the backlog. Changes to the preliminary valuation may result in material adjustments to the fair value of assets and liabilities acquired.

During the three months ended December 31, 2021, the Company made adjustments to the initial purchase price allocation of accounts receivable and accounts payable in the amount of $80.. The following table summarizes the preliminary allocation of the cost of the acquisition, as adjusted, to the assets acquired and liabilities assumed as of the close of the acquisition:
