The Company previously issued warrants to third parties, which had a five-year term to be converted to common stock at an exercise price of $0.004 per share. Outstanding warrants to purchase shares of common stock are held by persons who are not U.S. citizens. The warrants are not exercisable due to restrictions imposed by federal law requiring that no more than 24.9% of our stock be voted, directly or indirectly, or controlled by persons who are not U.S. citizens. The warrants can be converted to common stock upon warrant holders demonstrating U.S. citizenship. During June 2018, the Company extended the term of outstanding warrants set to expire by five years (through fiscal year 2023). Any warrants that were not extended were forfeited. On June 28, 2018, the Company agreed with GE Capital Aviation Services LLC (“GE Capital”) to terminate a warrant to purchase 250,000 shares of common stock held by GE Capital. Our shares of common stock became listed on The NASDAQ Global Select Market under the symbol “MESA” effective August 10, 2018. In July 2018, the Company’s Board of Directors and Compensation Committee approved the issuance of shares of restricted common stock under its 2018 Plan immediately following completion of the Company’s IPO to certain of its employees and directors in exchange for the cancellation of existing restricted phantom stock units, unvested restricted shares and SARs. The shares of restricted common stock issued under the 2018 Plan in exchange for the cancellation of restricted phantom stock units, unvested restricted shares and SARs are subject to vesting on the same terms set forth in the prior vesting schedules and are not subject to acceleration in connection with the 2018 Plan issuances. On August 8, 2018, the Company filed its Second Amended and Restated Articles of Incorporation, which, among other things: (i) effected a 2.5-for-1 stock split of its common stock; and (ii) increased the authorized number of shares of its common and preferred stock to 125,000,000 and 5,000,000, respectively. All references to share and per share amounts in the Company’s consolidated financial statements have been retrospectively revised to reflect the stock split and increase in authorized shares. On August 14, 2018, the Company completed its IPO, in which it issued and sold 9,630,000 shares of common stock, no par value, at a public offering price of $12.00 per share (the “Firm Shares”). Additionally, in connection with the IPO, the Company granted the underwriters an option to purchase up to an additional 1,444,500 shares of common stock at the same price. On September 11, 2018, the Company closed the sale of 1,344,500 shares (“Option Shares”) of its common stock, in connection with the partial exercise of the overallotment option granted to the underwriters in its IPO. Of the 1,344,500 Option Shares sold, 723,985 were purchased directly from the Company and the remaining 620,515 shares were purchased directly from the selling shareholders. The Firm Shares and Option Shares were sold to the public for a price of $12.00 per share. The aggregate gross proceeds to us from the IPO were approximately $124.2 million. We received $111.7 million in net proceeds after deducting $8.7 million of underwriting discounts and commissions and $3.8 million in offering costs. We have not historically paid dividends on shares of our common stock. Additionally, our RASPRO Lease Facility and GECAS Lease Facility contain restrictions that limit our ability to or prohibit us from paying dividends to holders of our common stock.
