Highly liquid investments with an original maturity of three months or less at time of purchase are included in cash and cash equivalents on the consolidated balance sheets.

Level 1 assets are priced using quoted prices in active markets for identical assets which include money market funds, U.S. Treasury securities and mutual funds as these specific assets are liquid.

Level 2 available-for-sale securities are priced using quoted market prices for similar instruments or nonbinding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted

market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets and liabilities. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs.

There were no transfers between levels during the years ended December 31, 2023, 2022, and 2021.

As of December 31, 2023, the Schuler Purchase Obligation, which is classified as a financial instrument asset and included in purchase obligation put option asset on the consolidated balance sheets, has a fair value of $3.4 million, using Level 3 measurement assumptions. See Note 11, Related Party Transactions for further detail on the Schuler Purchase Obligation.

For certain other financial assets and liabilities, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

Liabilities for which Fair Value is only Disclosed

At December 31, 2023, the Company’s 5.00% Notes, issued in June 2023, had an outstanding principal balance of $67.6 million and a fair value of $50.8 million, using Level 3 measurement assumptions.

The 2.50% Notes matured on March 15, 2023 and became due and payable on such date. The amortized carrying amount of the 2.50% Notes is $0.7 million as of December 31, 2023 and approximates the related fair value due to the instrument being fully matured and payable. As of December 31, 2022, the 2.50% Notes represented a Level 2 measurement with an outstanding principal balance of $56.6 million with a fair value of $51.9 million.

As of December 31, 2022, the Secured Note had an outstanding principal balance of $34.9 million, and a fair value of $16.0 million, using Level 3 measurement assumptions. The Secured Note was not outstanding as of December 31, 2023.

The warrant is an instrument measured at fair value on a non-recurring basis using Level 3 inputs. The estimated fair value of the warrant on August 15, 2022 was $3.8 million. See See Note 11, Related Party Transactions for further detail on the Company’s warrant with a related-party.

See Note 10, Convertible Notes for further detail on the 5.00% Notes and the 2.50% Notes and see Note 11, Related Party Transactions for further detail on the Secured Note.
