Goodwill and Intangible Assets, Net | Note 8. Goodwill and Intangible Assets, Net The following is a summary of the changes in the carrying amount of goodwill (in thousands): Balance at September 30, 2022 Balance at December 31, 2021 Gross Accumulated Net Gross Accumulated Net Goodwill $ 16,613 $ 16,613 $ — $ 16,613 $ — $ 16,613 Goodwill is tested for impairment annually as of October 1, or more frequently if events or circumstances indicate that the carrying value may no longer be recoverable and that an impairment may have occurred. The Company operates as one segment and one reporting unit, and therefore goodwill is tested for impairment at the entity level. During the three months ended September 30, 2022, the market price of Teknova’s common stock and market capitalization declined significantly. Given the significance of this decline, the Company performed interim goodwill impairment testing. The fair value of the Company was determined using a combination of an income approach and market approach. The income approach was based on the present value of future cash flows, which were derived from financial forecasts, and requires significant assumptions and judgement including among others, a discount rate and a terminal value. Fair values were based on expected future cash flows using Level 3 inputs under ASC 820, Fair Value Measurement . The cash flows are those expected to be generated by the Company, discounted at the weighted average cost of capital. The present value of future cash flows was determined by discounting estimated future cash flows at an 18.0 % weighted average cost of capital, which considers the risk of achieving the projected cash flows, long-term growth rate, the risk applicable to the Company, industry and market as a whole. The guideline public company method, a market approach method, was also used to estimate the fair value of the Company. The guideline public company method utilizes the trading multiples of similarly traded public companies. The unobservable inputs used to measure the fair value primarily included projected revenue growth rates and the determination of appropriate market comparison companies. Selected multiples were considered and applied to the trailing-twelve-month and next-twelve-month enterprise value-to-revenue multiples. The resulting estimated fair value was reconciled to the Company’s market capitalization. The reconciliation included an estimated implied control premium above the Company's market capitalization on September 30, 2022 of approximately 25 %. Based on the results of the impairment test, the Company determined goodwill was fully impaired and recorded an impairment charge of $ 16.6 million during the three months ended September 30, 2022.
