Insider Trading Policies and Procedures

The Company hasadopted a Statement of Policy on Insider Trading (the “insider trading policy” or “insider trading policy guidelines”) that describes our standards regarding the prohibition on trading, and causing the trading of securities while in possession of certain material nonpublic information, which the Company believes are reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as any listing standards applicable to the Company (including Nasdaq listing standards). Our insider trading policy is applicable to all of our directors, officers, employees, consultants, certain of their family members, and entities under the control of such persons. The policy attempts to establish standards that will avoid even the appearance of improper transactions on the part of insiders to preserve the Company’s reputation for adhering to the highest standards of conduct.

The insider trading policy guidelines, among other things, prohibits the unauthorized disclosure of material nonpublic information about the Company or any company with which the Company deals. The insider trading policy prohibits trading in Company securities or “tipping” on the basis of material nonpublic information. These guidelines also provide certain specific exceptions for various transactions including, for example, (i) stock option exercises where no sale is made, (ii) the vesting of restricted stock awards or tax withholding requirements in connection therewith, (iii) bona fide gifts of securities, and (iv) Rule 10b5-1 plans. The insider trading policy further restricts trading and other transactions for a limited group of designated persons, including, for example, members of our Board of Directors, executive officers, and employees during certain “Blackout Periods” that follow the end of a given fiscal period. These designated persons are also required to pre-clear any trades in the Company’s securities in accordance with the insider trading policy.

Our insider trading policy guidelines further acknowledge that short sales, buying or selling publicly traded options, hedging transactions in the Company’s stock (including prepaid variable forwards, equity swaps, collars and exchange funds), margin accounts, pledged securities and standing and limit orders (outside of an approved Rule 10b5-1 plan) may permit a holder to continue to own our common stock obtained through benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, our directors, employees, and officers to whom our policy applies, may no longer have the same objectives as our other stockholders. As such, the Company’s employees, consultants and directors are prohibited from engaging in such transactions (except as otherwise may be approved in writing by the Company).

A copy of the Longeveron Inc. insider trading policy is filed as Exhibit 19.1 to this Form 10-K.
