Note 7 Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market, or if none exists, the most advantageous market, for the specific asset or liability at the measurement date (the exit price). The fair value is based on assumptions that market participants would use when pricing the asset or liability. A fair value measurement is assigned a level within the fair value hierarchy, depending on the source of the inputs utilized in estimating the fair value measurement as follows:

The carrying amounts of cash and cash equivalents, accounts receivable, contract assets, contract liabilities, and accounts payable approximate their fair values due to the short-term maturities of these financial instruments.

Fair Value of Legacy Terran Orbital’s Common Stock

Prior to the Tailwind Two Merger, there was no public market for Legacy Terran Orbital’s common stock. As such, the fair value of Legacy Terran Orbital’s common stock was estimated using an option pricing model, which allocated the total enterprise value of the Company to the different classes of equity as of the valuation date.

The significant assumptions used in the option pricing model included: (i) total enterprise value of Legacy Terran Orbital based on the guideline publicly-traded company method, guideline transaction method, market calibration method and discounted cash flow method; (ii) liquidation preferences, conversion values, and participation thresholds of different equity classes; (iii) probability-weighted time to a liquidity event; (iv) expected volatility based upon the historical and implied volatility of common stock for the Company’s selected peers; (v) expected dividend yield of zero as the Company does not have a history or plan of declaring dividends on its common stock; (vi) risk-free interest rate based on U.S. treasury bonds with a zero-coupon rate, (vii) implied valuation, timing, and probability of the Tailwind Two Merger; and (viii) a discount for the lack of marketability of Legacy Terran Orbital’s common stock at that time. The fair value of Legacy Terran Orbital’s common stock represented a Level 3 fair value measurement.

Following the Tailwind Two Merger, there is a public market for Terran Orbital Corporation’s common stock and certain warrant and derivative liabilities. Accordingly, the fair value of Terran Orbital Corporation’s common stock and applicable warrant and derivative liabilities is based on the closing price on the relevant valuation date as reported on the NYSE.

Warrant and Derivative Liabilities

The fair values of certain warrant and derivative liabilities were estimated using the Black-Scholes option-pricing model, which uses the following significant inputs and assumptions for each security as of the valuation date: (i) the price per share of common stock, (ii) the exercise price, (iii) the risk-free interest rate, (iv) the dividend yield, (v) the contractual term, and (vi) the estimated volatility. The resulting fair values represent Level 3 fair value measurements.

The fair values of certain warrant and derivative liabilities were estimated using models similar to that of the Black-Scholes option-pricing model and included additional assumptions. Depending on the circumstances and features of the instruments, additional assumptions included or consisted of: (i) the estimated counterparty credit spread based on an estimated credit rating of CCC and below, (ii) the implied valuation, timing, and probability of closing the Tailwind Two Merger, (iii) the estimated redemption rate of the Tailwind Two’s public shareholders, and (iv) a discount for the lack of marketability of Legacy Terran Orbital’s common stock. The resulting fair values represent Level 3 fair value measurements.

The final fair values of certain warrants and derivatives were based on the number of shares of Terran Orbital Corporation common stock issued as part of the Tailwind Two Merger and the price per share of Terran Orbital Corporation's common stock as of the Tailwind Two Merger and represent Level 1 fair value measurements.

The fair value of the Public Warrants was based on their quoted market price as of each valuation date and represents a Level 1 fair value measurement. As the Private Placement Warrants are substantially similar to the Public Warrants, their fair value was based on the quoted market price of the Public Warrants as of each valuation date and represents a Level 2 fair value measurement.

The fair value of the Conversion Option Derivative was estimated as the difference in the fair value of the Convertible Notes due 2027 inclusive of the conversion option and the fair value of the Convertible Notes due 2027 exclusive of the conversion option. The fair value inclusive of the conversion option was estimated using a lattice model with the following significant inputs and assumptions: (i) time to maturity, (ii) coupon rate, (iii) discount rate based on an estimated credit rating of CCC and below, (iv) risk-free interest rate, (v) contractual features such as prepayment options, call premiums and default provisions, (vi) price per share of common stock, (vii) dividend yield, and (viii) estimated volatility. The fair value exclusive of the conversion option was estimated using a discounted cash flow method using a discount rate based on an estimated credit rating of CCC and below plus a risk-free interest rate. The resulting fair values represent Level 3 fair value measurements.

The assumptions underlying the above valuations represented the Company’s best estimate, which involved inherent uncertainties and the application of judgment. If the Company had used different assumptions or estimates, the fair values above could have been materially different.

Long-term Debt

As of December 31, 2022, the fair value of the Company's long-term debt, except as otherwise described, was estimated using a lattice model with the following significant inputs and assumptions: (i) time to maturity, (ii) coupon rate, (iii) discount rate based on an estimated credit rating of CCC and below, (iv) risk-free interest rate, and (v) contractual features such as prepayment options, call premiums and default provisions. The fair value related to Convertible Notes due 2027 was exclusive of the conversion option and estimated as described above. The fair value of long-term debt related to the PIPE Investment Obligation was estimated using a discounted cash flow method applied to the remaining quarterly payments using a discount rate based on a risk-free rate derived from constant maturity yields ranging plus a credit risk derived from an estimated credit rating of CCC and below. The resulting fair values represent Level 3 fair value measurements.

As of December 31, 2021, the fair value of the Company's long-term debt was estimated using a lattice model with the following significant inputs and assumptions: (i) time to maturity, (ii) coupon rate, (iii) discount rate based on an estimated credit rating of CCC and below, (iv) risk-free interest rate, (v) contractual features such as prepayment options, call premiums and default provisions, and (vi) probability of a liquidity event. The resulting fair values represent Level 3 fair value measurements.
