Fair Value Measurements |
Fair Value Measurements | 3. Fair Value Measurements ​ Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels as follows: ​ ●Level 1—Inputs to the valuation based upon quoted prices (unadjusted) for identical assets or liabilities in active markets that are accessible as of the measurement date. ​ ●Level 2—Inputs to the valuation include quoted prices in either markets that are not active, or in active markets for similar assets or liabilities, inputs other than quoted prices that are observable, and inputs that are derived principally from or corroborated by observable market data. ​ ●Level 3—Inputs to the valuation that are unobservable inputs for the asset or liability. ​ The Company’s financial assets measured at fair value on a recurring basis at October 28, 2023, were as follows (in thousands): ​

​ On May 3, 2021, the Company closed its acquisition of Telerob Gesellschaft für Fernhantierungstechnik mbH (“Telerob GmbH”), including Telerob GmbH’s wholly-owned subsidiary, Telerob USA, Inc. (“Telerob USA,” and collectively with Telerob GmbH, “Telerob”) pursuant to its Share Purchase Agreement (the “Telerob Purchase Agreement”) with Unmanned Systems Investments GmbH (the “Telerob Seller”). Pursuant to the Telerob Purchase Agreement, the Telerob Sellers may receive up to a maximum of €6,000,000 (approximately $6,339,000) in additional cash consideration if specific revenue and contract award targets for Telerob are achieved during the 36 month period after closing. The contingent consideration was valued using a Black-Scholes option-pricing model. The analysis considered, among other items, contractual terms of the Telerob Purchase Agreement, the Company’s discount rate, the timing of expected future cash flows and the probability that the revenue and contract award targets required for payment of the contingent consideration will be achieved. The fair value of the contingent consideration is recorded in other current liabilities on the condensed consolidated balance sheet. The first year earnout of €2,000,000 (approximately $2,116,000) was not achieved. During the fiscal year ended April 30, 2023, the second year earnout of €2,000,000 (approximately $2,116,000) was achieved and was paid in November 2023. The third earnout of €2,000,000 (approximately $2,116,000) is not expected to be achieved. ​ On September 12, 2022, the Company invested $5,000,000 and acquired 500,000 shares and 500,000 privately placed, redeemable warrants of Amprius Technologies, Inc. The privately placed, redeemable warrants have an exercise price of $12.50 and redemption price of $20.00. The Company measures the fair value of the privately placed, redeemable warrants using the quoted market price of the public warrants which have an exercise price of $11.50 and a redemption price of $18.00 and classifies the warrants as a level 2 fair value measurement. On September 9, 2022, the Company acquired 10,000 shares of Nauticus Robotics, Inc. for $100,000.
