Sky Harbour Group LLC and Yellowstone Acquisition Company Announce Up to $70 Million Forward-Purchase Agreement in Connection with Proposed Business Combination

January 18, 2022

OMAHA, Neb.--(BUSINESS WIRE)--Sky Harbour LLC (“Sky”), which aims to address the shortage of private aviation hangars in many areas across the country by establishing a network of turnkey upscale business aviation hangar complexes, and Yellowstone Acquisition Company (“Yellowstone” or the “Company”) (NYSE: YSAC, YSACU, YSACW), a publicly-traded special purpose acquisition company, today announced that in connection with their proposed business combination (the “Business Combination”), Yellowstone has entered into a forward purchase agreement for up to $70 million with an affiliate of Atalaya Capital Management LP (“Atalaya”), a privately held, SEC-registered alternative investment advisory firm that focuses primarily on private credit and special opportunities investments.

On January 17, 2022, Yellowstone and ACM ARRT VII E LLC (“Seller”), entered into an agreement (the “FPA”) for an Equity Prepaid Forward Transaction (the “FP Transaction”). Pursuant to the terms of the FPA, (a) Seller intends, but is not obligated, to purchase shares (the “Subject Shares”) of Class A common stock of the Company (the “Shares”) after the date of the FPA from holders of Shares (other than the Company, Boston Omaha Corporation or their affiliates) who have redeemed Shares or indicated an interest in redeeming Shares pursuant to the redemption rights set forth in the Company’s charter in connection with the Business Combination and (b) Seller has agreed to waive all redemption rights with respect to any Subject Shares in connection with the Business Combination so long as the FPA and the Equity Purchase Agreement are not terminated prior to the closing of the Business Combination and the closing of the Business Combination occurs prior to the Outside Closing Date (as defined in the Equity Purchase Agreement). The number of Subject Shares shall be no more than the lesser of (i) 7,000,000 and (ii) the maximum number of Shares such that Seller does not beneficially own greater than 9.9% of the Shares on a post- combination pro forma basis. If the Seller acquires less than 2,500,000 Subject Shares, it has agreed to acquire additional Shares (“Additional Shares”) from the Company in a private placement which will be subject to the FPA such that the sum of the number of Additional Shares and the number of Subject Shares will be equal to 2,500,000.

The FPA provides that (a) one local business day following the closing of the Business Combination, the Company will pay to Seller, out of the funds held in the Company’s trust account, an amount (the “Prepayment Amount”) equal to the Redemption Price (as defined in Yellowstone’s Amended and Restated Certificate of Incorporation of the Company (the “ Certificate of Incorporation”) per Share (the “Initial Price”) multiplied by the aggregate number of Subject Shares and Additional Shares, if any, (together, the “Number of Shares”) on the date of such prepayment, (b) on the first local business day of each calendar quarter after the closing of the Business Combination, the Company will pay to Midtown Madison Management LLC a structuring fee in the amount of $2,500 per quarter and (c) on the date occurring one settlement cycle following the valuation date (which shall occur on the earlier of (i) 18 months after the closing of the Business Combination and (ii) the date specified by Seller in a written notice (not earlier than the day such notice is effective) that, during any 30 consecutive scheduled trading day-period following the closing of the Business Combination, the volume weighted average trading price per Share for 20 scheduled trading days during such period shall have been equal to or less than $5.00 per Share), the Seller shall deliver to the Company the Number of Shares less any Terminated Shares, as described below.

From time to time and on any scheduled trading day after the closing of the Business Combination, Seller may sell Subject Shares or Additional Shares (or any other shares of common stock or other securities of the Company) at its absolute discretion in one or more transactions, publicly or privately, and, in connection with such sales, terminate the FP Transaction in whole or in part in an amount corresponding to the number of Subject Shares or Additional Shares sold (the “Terminated Shares”). At the end of each calendar month during which any such early termination occurs, Seller will pay to the Company an amount equal to the product of (x) the number of shares terminated during such calendar month and (y) the Reset Price, where “Reset Price” refers to, initially, the Initial Price, provided that upon the closing of any follow-on offering of Shares registered under the Securities Act of 1933, as amended, at a price per Share that is lower than the then current Reset Price, the Reset Price will be reduced to equal such price per Share. Seller’s obligations to the Company under the FPA are secured by perfected liens on (i) the cash proceeds of any sale, transfer or other disposition of the Subject Shares, (ii) the deposit account (the “Deposit Account”) into which such cash proceeds (subject to certain carve-outs) are required to be deposited and (iii) proceeds and products of the foregoing. The Deposit Account will be subject to a customary deposit account control agreement in favor of the Company.

Disclosure On Redemptions Relating to the Agreement.

Seller has agreed to waive all redemption rights under the Company’s Certificate of Incorporation that would require redemption by the Company of the Subject Shares. Such waiver may reduce the number of shares of common stock redeemed in connection with the Business Combination, which reduction could alter the perception of the potential strength of the Business Combination.

Yellowstone Acquisition Company Announces Additional $45 Million Common Stock PIPE Subscription for Sky Harbour Group Business Combination Bringing Total to $100 Million

Sky Harbour Group LLC Agrees to Waive Minimum Financing Condition to Complete Business Combination

December 22, 2021

OMAHA, Neb.--(BUSINESS WIRE)--Yellowstone Acquisition Company (the “Company” or “Yellowstone”) (NASDAQ:YSAC, YSACU, YSACW), a special purpose acquisition company, announced today that Boston Omaha Corporation, through its subsidiary BOC YAC, LLC, has agreed to provide $45 million of PIPE financing in connection with the closing of the potential business combination with Sky Harbour LLC (“Sky”), in addition to the $55 million Series B investment that will convert to Class A common stock upon completion of the business combination. Boston Omaha is committing $100 million in total to Sky for the acceleration of Sky’s business plan. The PIPE Financing will be provided through the purchase of Yellowstone Class A common stock at a price of $10.00 per share immediately prior to the closing of the business combination. BOC YAC, LLC has executed a PIPE Subscription Agreement to provide the additional $45 million in equity financing. In consideration of the investment, Sky has agreed to waive the $150 million minimum financing condition (as described below) which required that the Company deliver cash proceeds of at least $150 million (after payment of certain expenses) to Sky as a condition precedent to consummating the business combination.

The Equity Purchase Agreement the parties entered into on August 1, 2021 required that Boston Omaha provide to Sky a backstop (consisting of securities and/or cash) through the purchase of additional shares of YAC Class A common stock, at a price of $10.00 per share immediately prior to the consummation of the business combination if needed, as described below (the “Back-Stop Financing”) in the event that (i) the amount of cash available in the Trust Account immediately prior to closing after deducting only the amounts payable to holders who have validly redeemed their Class A Common Stock plus (ii) the BOC YAC previous investment of $55 million, and (iii) any additional financing amounts (including through a Subsequent PIPE) actually received prior to or substantially concurrently with the closing is less than $150 million (the “Minimum Available Buyer Financing Amount”), Yellowstone and Sky have agreed that the funding of the BOC PIPE will be in lieu of, and will satisfy, Boston Omaha’s obligation to provide the Backstop Financing. The sum of (i), (ii) and (iii) in the preceding sentence, plus the amount of Back-Stop Financing actually funded, if any, is referred to as the “Available Buyer Financing.” The Back-Stop Financing was to be funded in an amount not to exceed $45 million which would be sufficient to cause the Available Buyer Financing to equal the Minimum Available Buyer Financing Amount. Instead, the BOC PIPE will be funded in accordance with the terms of the BOC PIPE Subscription Agreement.

Boston Omaha Announces Closing of Yellowstone Acquisition Company $125 Million Initial Public Offering

October 26, 2020 05:43 PM Eastern Daylight Time, Business Wire

OMAHA, Neb.--(BUSINESS WIRE)--Boston Omaha Corporation (NASDAQ:BOMN) (“Boston Omaha”) announced today that Yellowstone Acquisition Company (“Yellowstone”) closed its initial public offering (the “IPO”) of 12,500,000 units at a price of $10.00 per unit, resulting in gross proceeds of $125,000,000. The units began trading on the NASDAQ Stock Market, LLC (“NASDAQ”) under the ticker symbol “YSACU” on October 22, 2020. BOC Yellowstone LLC, a subsidiary of Boston Omaha, served as the sponsor (the “Sponsor”) for Yellowstone’s IPO.

Each unit issued in the IPO consists of one share of Yellowstone’s Class A common stock and one-half of one warrant, each whole warrant entitling the holder thereof to purchase one share of Class A common stock at an exercise price of $11.50 per share. After the securities comprising the units begin separate trading, the shares of Class A common stock and warrants are expected to be listed on NASDAQ under the symbols “YSAC” and “YSACW,” respectively. No fractional warrants will be issued upon separation of the units and only whole warrants will trade.

The Sponsor has purchased an aggregate of 7,500,000 warrants (which can increase to 7,875,000 warrants if the over-allotment option is exercised in full) at a price of $1.00 per whole warrant ($7,500,000 in the aggregate, or $7,875,000 if the over-allotment option is exercised in full) in a private placement that closed simultaneously with the closing of the IPO (the "private placement warrants”). Each whole private placement warrant is exercisable to purchase one whole share of Yellowstone's Class A common stock at $11.50 per share. In addition, the Sponsor acquired 3,593,750 shares of Yellowstone's Class B common stock (up to 468,750 shares of which are subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised) for a purchase price of $25,000. The shares of Class B common stock will automatically convert into shares of Class A common stock at the time, if any, when Yellowstone completes an initial business combination, on a one-for-one basis, subject to certain adjustments. In the event a business combination is not consummated within 15 months following the IPO, then $127,500,000 of the proceeds raised in the IPO and through the sale of the private placement warrants will be paid to redeem the shares of Class A common stock sold to the public.

  • No officer or director of Boston Omaha shall receive any equity issued to the Sponsor.
  • Yellowstone has not selected any potential business combination target.

The purpose of the IPO is to pursue a business combination in an industry other than the three industries in which Boston Omaha currently owns and operates businesses: outdoor advertising, surety insurance and broadband services businesses. For further information regarding the terms of the IPO and the rights and obligations of the Sponsor, please refer to the Yellowstone Prospectus on file with the SEC at www.sec.gov.

Boston Omaha elected to proceed with a SPAC public offering for the following reasons:

  • Boston Omaha intends to use its existing capital for the three business lines in which it currently operates: outdoor advertising, surety insurance and fiber-to-the-home broadband services as well as investing in other future potential acquisitions and making other investments. By teaming with other public investors in the IPO, Yellowstone has the ability to pursue business combinations with larger companies than Boston Omaha could pursue currently on a stand-alone basis.
  • There are many owner-operated businesses interested in minority owners for growth capital. Boston Omaha has invested in a number of these types of businesses. However, Boston Omaha's ability to acquire a significant equity stake in a larger business through a business combination is limited by the Investment Company Act of 1940 (as amended), which requires a company which holds more than 40% of its assets in minority investments in other businesses to register under the Investment Company Act. This requirement prevents Boston Omaha on a stand-alone basis from consummating larger deals in which it would own a minority interest in a business, thus currently preventing or otherwise significantly limiting its ability to engage in larger business combinations.
  • Acquiring a large percentage of equity in certain businesses, such as regulated financial institutions, would require Boston Omaha to comply with very burdensome and expensive regulations which would both limit its overall business operations due to capital and other financial testing covenants and adversely impact its ability to acquire other businesses which would not otherwise be subject to these regulations.

Wells Fargo Securities served as the sole book runner for the IPO. Yellowstone has granted the underwriters a 45-day option to purchase up to an additional 1,875,000 units at the initial public offering price to cover over-allotments, if any. The offering was made only by means of a prospectus. Copies of the prospectus may be obtained, when available, from Wells Fargo Securities, Attention: Equity Syndicate Department, 500 West 33rd Street, New York, New York, 10001, at (800) 326-5897 or email a request to cmclientsupport@wellsfargo.com. A registration statement relating to the securities offered by Yellowstone was filed with the Securities and Exchange Commission (“SEC”) and became effective on October 21, 2020. This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
