Vesting rights that will generally vest on the later to occur of: (i) the first anniversary of the consummation of the Tailwind Two Merger and (ii) the trading price of the Company’s common stock equaling or exceeding $11.00 or $13.00, as applicable, for any 20 trading days within any consecutive 30-trading day period. The Retention RSUs expire five years from the Tailwind Two Merger if unvested. The derived service period for the majority of the Retention RSUs was estimated to be less than one year from the date of the Tailwind Two Merger based on the median weighted-average triggering event period determined using the Monte Carlo simulation model. As such, the share-based compensation expense associated with the Retention RSUs is generally recognized over a one-year period beginning from the consummation of the Tailwind Two Merger. In addition, the grant date fair value of the Retention RSUs was determined using the Monte Carlo simulation model using the following significant inputs and assumptions as of the valuation date: (i) the price per share of Terran Orbital Corporation’s common stock, (ii) a risk-free interest rate ranging from 1.61% to 2.88%, (iii) a dividend yield of 0%, (iv) an estimated volatility of 40%, and (v) a discount for lack of marketability ranging from 4.50% to 6.50% for Retention RSUs granted prior to the Tailwind Two Merger.
