 management’s methodology for developing each of the assumptions used in the Black-Scholes model is as follows:

Fair value of common stock

The Company uses the quoted market price of its common stock as its fair value.

Expected volatility

Through 2020, since OpGen did not have sufficient history to estimate the expected volatility of its common stock price, expected volatility was based on the volatility of peer public entities that were similar in size and industry. Beginning in 2021, for stock options with an expected term where there is sufficient history available, expected volatility is based on the volatility of OpGen’s common stock.

Expected dividend yield

The Company has never declared or paid dividends on its common stock and has no plans to do so in the foreseeable future.

Risk-free interest rate

The risk-free interest rate is the U.S. Treasury rate for the day of each option grant during the year, having a term that most closely resembles the expected term of the option.

Expected term

The expected term of a stock option grant is the period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of 10 years. The Company uses the simplified method to estimate the expected term of stock options, as permitted by SAB No. 107 and SAB No. 110, due to limited historical exercise data. Under this method, the expected term is calculated as the midpoint between the vesting period and the contractual term. Accordingly, the Company estimates an expected term of 5.75 years for options with a standard two-year vesting period and 6.25 years for options with a standard four-year vesting period. Over time, management will track actual terms of the options and adjust their estimate accordingly so that estimates will approximate actual behavior for similar options.

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred income tax assets to the amount expected to be realized.

Tax benefits are initially recognized in the financial statements when it is more likely than not
