NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2023

(in thousands, except share data)

Sky Harbour Group Corporation (“SHG”) is a holding company organized under the laws of the State of Delaware and, through its main operating subsidiary, Sky Harbour LLC and its subsidiaries (collectively, “Sky”), is an aviation infrastructure development company that develops, leases and manages general aviation hangars for business aircraft across the United States. Sky Harbour Group Corporation and its consolidated subsidiaries are collectively referred to as the “Company.”

The Company is organized as an umbrella partnership-C corporation, or “Up-C”, structure in which substantially all of the operating assets of the Company are held by Sky and SHG’s only substantive assets are its equity interests in Sky (the “Sky Common Units”). As of March 31, 2023, SHG owned approximately 26.2% of the Sky Common Units and the prior holders of Sky Common Units (the “LLC Interests”) owned approximately 73.8% of the Sky Common Units and control the Company through their ownership of the Company's Class B Common Stock, $0.0001 par value (“Class B Common Stock”).

Basis of Presentation

The accompanying unaudited consolidated financial statements and the related notes (the “Financial Statements”) have been prepared in conformity with the U.S. Securities and Exchange Commission (the “SEC”) requirements for quarterly reports on Form 10-Q, and consequently exclude certain disclosures normally included in audited consolidated financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).These Financial Statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Financial Statements should be read in conjunction with the audited consolidated financial statements and the notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which includes additional disclosures and a summary of the Company's significant accounting policies. In the Company’s opinion, these Financial Statements include all adjustments, consisting of normal recurring items, considered necessary by management to fairly state the Company’s results of operation, financial position, and cash flows.

Certain historical amounts have been reclassified to conform to the current year’s presentation, including salaries, wages, and benefits associated with operations personnel employed at the Company's hangar development sites. $89 previously classified within general and administrative expenses on the consolidated statement of operations for the three months ended March 31, 2022, has been reclassified to operating expenses. This reclassification had no effect on total expenses, net loss, net loss per common share and had no impact on the Company’s consolidated balance sheets, statement of stockholders’ equity and statement of cash flows for the prior year period.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include assumptions used within impairment analyses, estimated useful lives of depreciable assets and amortizable costs, estimates of inputs utilized in determining incentive compensation expense and financial instruments such as warrants, and estimates and assumptions related to right-of-use assets and operating lease liabilities. Actual results could differ materially from those estimates.

Risks and Uncertainties

The Company’s operations have been limited to-date. For most of its history, the Company was engaged in securing access to land through ground leases, and developing and constructing aviation hangars. The major risks faced by the Company is its future ability to obtain additional tenants for the facilities that it constructs, and to contract with such tenants for rental income in an amount that is sufficient to meet the Company’s financial obligations, including increasing construction costs due to inflation.

Liquidity and Capital Resources

As a result of ongoing construction projects and business development activities, including the development of aircraft hangars and the leasing of available hangar space, the Company has incurred recurring losses and negative cash flows from operating activities since its inception. The Company expects to continue to invest in such activities and generate operating losses in the near future.

The Company obtained long-term financing through bond and equity offerings to fund its construction, lease, and operational commitments, and believes its liquidity is sufficient to allow continued operations for more than one year after the date these financial statements are issued.

Significant Accounting Policies

Basis of Consolidation

SHG is deemed to have a controlling interest of Sky through its appointment as the Managing Member of Sky, in which SHG has control over the affairs and decision-making of Sky. The interests in Sky not owned by the Company are presented as non-controlling interests. Sky’s ownership percentage in each of its consolidated subsidiaries is 100%. There are no unconsolidated variable interest entities (“VIEs”) in which Sky is considered to be the primary beneficiary.

Cost of Construction

Cost of construction on the consolidated balance sheets is carried at cost. The cost of acquiring an asset includes the costs necessary to bring a capital project to the condition necessary for its intended use. Costs are capitalized once the construction of a specific capital project is probable. Construction labor and other direct costs of construction are capitalized. Professional fees for engineering, procurement, consulting, and other soft costs that are directly identifiable with the project and are considered an incremental direct cost are capitalized. The Company allocates a portion of its internal salaries to both capitalized cost of construction and to general and administrative expense based on the percentage of time certain employees worked in the related areas. Interest, net of the amortization of debt issuance costs and premiums, and net of interest income earned on bond proceeds, is also capitalized until the capital project is completed.

Once a capital project is complete, the Company begins to depreciate the constructed asset on a straight-line basis over the lesser of the life of the asset or the remaining term of the related ground lease, including expected renewal terms. 

Leases

The Company accounts for leases under Accounting Standards Codification (“ASC”) Topic 842, Leases. The Company determines whether a contract contains a lease at the inception of the contract. ASC Topic 842 requires lessees to recognize lease liabilities and right-of-use (“ROU”) assets for all operating leases with terms of more than 12 months on the consolidated balance sheets. The Company has made an accounting policy election to not recognize leases with an initial term of 12 months or less on the Company’s consolidated balance sheets and will result in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. When management determines that it is reasonably certain that the Company will exercise its options to renew the leases, the renewal terms are included in the lease term and the resulting ROU asset and lease liability balances.

The Company also has tenant leases and accounts for those leases in accordance with the lessor guidance under ASC Topic 842.

The Company has lease agreements with lease and non-lease components; the Company has elected the accounting policy to not separate lease and non-lease components for all underlying asset classes.

The Company has not elected to capitalize any interest cost that is implicit within its operating leases into cost of construction on the consolidated balance sheet, but instead, expenses its ground lease cost in the consolidated statements of operations.

Warrants liability

The Company accounts for the warrants assumed in the Yellowstone Transaction (see Note 9) in accordance with the guidance contained in ASC Topic 815, “Derivatives and Hedging” (“ASC 815”), under which warrants that do not meet the criteria for equity classification and must be recorded as derivative liabilities. Accordingly, the Company classifies the warrants as liabilities carried at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the warrants are exercised or expire, and any change in fair value is recognized in the consolidated statement of operations.

Revenue recognition

The Company leases the hangar facilities that it constructs to third parties. The lease agreements are either on a month-to-month basis or have a defined term and may have options to extend the term. Some of the leases contain options to terminate the lease by either party with given notice. There are no options given to the lessee to purchase the underlying assets. Rental revenue is recognized in accordance with ASC Topic 842, Leases (see Note 7) and includes (i) fixed payments of cash rents, which represents revenue each tenant pays in accordance with the terms of its respective lease and is recognized on a straight-line basis over the term of the lease and (ii) variable payments of tenant reimbursements, which are recoveries of all or a portion of the common area maintenance and operating expenses of the property and are recognized in the same period as the expenses are incurred. As of March 31, 2023 and December 31, 2022, the deferred rent receivable included in prepaid expenses and other assets was $120 and $83, respectively.

The Company evaluates the collectability of tenant receivables for payments required under the lease agreements. If the Company determines that collectability is not probable, the Company recognizes any difference between revenue amounts recognized to date under ASC 842 and payments that have been collected from the lessee, including security deposit amounts held, as a current period adjustment to rental revenue. There were no material adjustments to rental revenue for uncollectible tenant rental payments in either of the three and nine months ended March 31, 2023 or 2022.

For the three months ended March 31, 2023 the Company derived approximately 45% of its revenue from three tenants, including 20% from a single tenant. For the three months ended March 31, 2022, the Company derived approximately 90% of its revenue from two tenants.

Income Taxes

SHG is classified as a corporation for Federal income tax purposes and is subject to U.S. Federal and state income taxes. SHG includes in income, for U.S. Federal income tax purposes, its allocable portion of income from the “pass-through” entities in which it holds an interest, including Sky. The “pass-through” entities, are not subject to U.S. Federal and certain state income taxes at the entity level, and instead, the tax liabilities with respect to taxable income are passed through to the members, including SHG. As a result, prior to the Yellowstone Transaction, Sky was not subject to U.S. Federal and certain state income taxes at the entity level.

The Company follows the asset and liability method of accounting for income taxes. This method gives consideration to the future tax consequences associated with the differences between the financial accounting and tax basis of the assets and liabilities as well as the ultimate realization of any deferred tax asset resulting from such differences, as well as from net operating losses and other tax-basis carryforwards. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. When a valuation allowance is increased or decreased, a corresponding tax expense or benefit is recorded.

The Company recorded income tax expense of $0 and the effective tax rate was 0.0% for the three months ended March 31, 2023 and March 31, 2022. The effective income tax rate for the three months ended March 31, 2023 and March 31, 2022 differs from the federal statutory rate of 21% primarily due to a full valuation allowance against net deferred tax assets as it is more likely than not that the deferred tax assets will not be realized.

Recently Adopted Accounting Pronouncements

Credit Losses (Topic 326)

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). Subsequent to the issuance of ASU 2016-13, the FASB clarified the guidance through several ASUs. The collective new guidance (ASC 326) generally requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used and establishes additional disclosures related to credit risks. The Company adopted this guidance using the modified retrospective method in the first quarter of fiscal year 2023. The adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Investments of the Company's cash in various U.S. Treasury securities have been classified as available-for-sale and are carried at estimated fair value utilizing Level 1 inputs as determined based upon quoted market prices.

Pursuant to provisions within the Master Indenture of the Series 2021 Bonds, as defined in Note 8, the Company invests the funds held in the restricted trust bank accounts in various U.S. Treasury securities. Therefore, such investments are reported as “Restricted investments” in the accompanying consolidated balance sheets. Unrealized losses on certain of the Company's investments and restricted investments are primarily attributable to changes in interest rates. The Company does not believe the unrealized losses represent impairments because the unrealized losses are due to general market factors. The Company has not recognized an allowance for expected credit losses related to its investments or restricted investments as the Company has not identified any unrealized losses attributable to credit factors during the three months ended March 31, 2023. The held-to-maturity restricted investments are carried on the consolidated balance sheet at amortized cost. As of March 31, 2023, the Company has the ability and intent to hold these restricted investments until maturity, and as a result, the Company would not expect the value of these investments to decline significantly due to a sudden change in market interest rates. The fair value of the Company’s restricted investments is estimated utilizing Level 1 inputs including prices for U.S. Treasury securities with comparable maturities on active markets.

The following tables are summaries of the amortized cost, unrealized gains, unrealized losses, and fair value by investment type as of March 31, 2023 and December 31, 2022:

The following table sets forth the maturity profile of the Company's investments and restricted investments as of March 31, 2023:

The Company’s portfolio as of March 31, 2023 includes the following completed and in-development projects:

Constructed assets, net, and cost of construction, consists of the following:

Depreciation expense for the three months ended March 31, 2023 and 2022 totaled $392 and $135, respectively.

Long-lived assets, net, consists of the following:

Depreciation expense for the three months ended March 31, 2023 and 2022 totaled $58 and $10, respectively. As of March 31, 2023 and December 31, 2022, equipment included approximately $87 and $650, respectively, of purchase deposits towards ground support equipment which are not being depreciated as the assets have not been placed into service.

Prepaid expenses and other assets

In  July 2022, the Company entered into a vendor agreement to acquire construction materials related to the Company's development projects (the “Vendor Agreement”). In connection with the Vendor Agreement, the Company entered into a revolving line of credit loan and security agreement (the "Vendor Loan Agreement"), whereby the Company agreed to provide up to $2.5 million of availability under a revolving credit line to fund the working capital requirements of the vendor. The Vendor Loan Agreement matures in  July 2029 and initially bears interest at a rate of 5% per annum for the first year, and increases by 1% per annum each year on the anniversary date of the Vendor Loan Agreement until its maturity.

In  December 2022, the Vendor Loan Agreement was amended to increase the commitment under the revolving line of credit to $4.5 million. In connection with the amendment of the Vendor Loan Agreement, the Company was granted an option to purchase a 51% interest in the vendor for nominal consideration (the "Vendor Purchase Option"). The Vendor Purchase Option is exercisable solely at the discretion of the Company and is deemed to have no fair value as its exercise price is essentially equivalent to the fair value of the underlying equity. The Vendor Purchase Option was exercised on May 12, 2023, see “Note 16 — Subsequent Events”. The Vendor Purchase Option does not confer any voting rights to the Company prior to its exercise.

As of March 31, 2023, and  December 31, 2022, the Company had loaned a total of $3.5 million and $2.2 million, respectively, to the vendor, the balance of which is presented as a component of Prepaid expenses and other assets within the Company's consolidated balance sheet.

Lessee

All of the Company’s leases are classified as operating leases under ASC Topic 842. Management has determined that it is reasonably certain that the Company will exercise its options to renew the leases, and therefore the renewal options are included in the lease term and the resulting ROU asset and operating lease liability balances. As the Company’s lease agreements do not provide a readily determinable implicit rate, nor is the rate available to the Company from its lessors, the Company uses its incremental borrowing rate to determine the present value of the lease payments.

The Company’s lease population does not include any residual value guarantees. The Company has operating leases that contain variable payments, most commonly in the form of common area maintenance and operating expense charges, which are based on actual costs incurred. These variable payments were excluded from the calculation of the ROU asset and operating lease liability balances since they are not fixed or in-substance fixed payments. These variable payments were not material in amount for both of the three month periods ended March 31, 2023 and 2022. Some of the leases contain covenants that require the Company to construct the hangar facilities on the leased grounds within a certain period and spend a set minimum dollar amount. For one of the leases, the shortfall (if any) must be paid to the lessor. See Note 14.

The Company’s ground leases have remaining terms ranging between 26 to 74 years, including options for the Company to extend the terms. These leases expire between 2049 and 2097, which include all lease extension options available to the Company. Certain of the Company's ground leases contain options to lease additional parcels of land at the Company's option within a specified period of time.

In  January 2023, the Company executed a lease amendment with the Town of Addison, Texas, to add two additional parcels of land (the "ADS Expansion Parcels") to the existing lease at ADS (the "ADS Lease"). The land associated with the ADS Expansion Parcels is expected to become available for possession no later than  June 2023 for one parcel and  July 2024 for the other. The lease term for the ADS Expansion Parcels will be 40 years from the completion of construction for each respective parcel, and will effectively extend the term of the existing ADS Lease to be co-terminus with the ADS Expansion Parcels. The ADS Lease and the ADS Expansion Parcels contain no additional extension options as the lease term is the maximum allowable term permitted by the Town of Addison.

In addition to the Company’s ground leases, the company has operating leases for office space and ground support vehicles.

Supplemental consolidated cash flow information related to the Company’s leases was as follows: 

Supplemental consolidated balance sheet information related to the Company’s leases was as follows: 

The Company’s future minimum lease payments required under leases as of  March 31, 2023 were as follows: 

Lessor

The Company leases the hangar facilities that it constructs to third-party tenants. These leases have been classified as operating leases. The Company does not have any leases classified as sales-type or direct financing leases. Lease agreements with tenants are either on a month-to-month basis or have a defined term with an option to extend the term. The defined term leases vary in length from one to five years with options to renew for additional term(s) given to the lessee. One of the agreements contains an option by either party to terminate with appropriate notice, as defined. There are no options given to the lessee to purchase the underlying assets.

The leases may contain variable fees, most commonly in the form of tenant reimbursements, which are recoveries of the common area maintenance and operating expenses of the property and are recognized as income in the same period as the expenses are incurred. The leases did not have any initial direct costs. The leases do not contain any restrictions or covenants to incur additional financial obligations by the lessee.

Tenant leases to which the Company is the lessor require the following non-cancelable future minimum lease payments from tenants as of  March 31, 2023:

Bonds payable

On May 20, 2021, Sky formed a new wholly-owned subsidiary, Sky Harbour Capital LLC (“SHC”), as a parent corporation to its wholly-owned subsidiaries that operate each of the aircraft hangar development sites under its ground leases. SHC and these subsidiaries form an Obligated Group (the “Obligated Group” or the “Borrowers”) under a series of bonds that were issued in September 2021 with a principal amount of $166.3 million (the “Series 2021 Bonds”). The members of the Obligated Group are jointly and severally liable under the Series 2021 Bonds. SHG and its other subsidiaries are not members of the Obligated Group and have no obligation to repay the bonds.

The Series 2021 Bonds are payable pursuant to a loan agreement dated September 1, 2021 between the Public Finance Authority (of Wisconsin) and the Borrowers. The payments by the Borrowers under the loan agreement are secured by a Senior Master Indenture Promissory Note, Series 2021-1 issued by the Obligated Group under an indenture (the “Master Indenture”). The obligations of the Borrowers are collateralized by certain leasehold and subleasehold deeds of trust or mortgages on the Borrowers’ interests in the development sites and facilities being constructed at each airport where the Borrowers hold ground leases. In addition, the Borrowers have assigned, pledged and granted a first priority security interest in all funds held under the Master Indenture and all right, title and interest in the gross revenues of the Borrowers. Furthermore, Sky, Sky Harbour Holdings LLC and SHC have each pledged as collateral its respective ownership interest in any of the Borrowers.

The Series 2021 Bonds have principal amounts, interest rates, and maturity dates as follow: $21.1 million bearing interest at 4.00%, due July 1, 2036; $30.4 million bearing interest at 4.00%, due July 1, 2041; and $114.8 million bearing interest at 4.25%, due July 1, 2054. The Series 2021 Bond that has a maturity date of July 1, 2036 was issued at a premium, and the Company received bond proceeds that were $0.2 million above its face value. The bond premium is being amortized as a reduction of interest expense over the life of the bond. Interest is payable on each January 1 and July 1, commencing January 1, 2022. Principal repayments due under the Series 2021 Bonds are paid annually, commencing July 1, 2032.

On  March 22, 2023, SHC elected to modify the scope of the Series 2021 Bonds pursuant to the terms of the Master Indenture, in order to reallocate a portion of the proceeds of the Series 2021 Bonds to its project site located at ADS (the “ADS Project”) . In connection with the election to modify the scope of the Series 2021 PABs to include the ADS Project, (i) Addison Hangars LLC (“Sky Harbour Addison”) and OPF Hangars Landlord LLC (“OPF Hangars”) joined as members of the Obligated Group, (ii) Sky Harbour Holdings LLC contributed its membership interest in OPF Hangars to SHC, (iii) SHC pledged its equity interest in each of Sky Harbour Addison and OPF Hangars to the Master Trustee as security for the obligations under the Series 2021 Bonds, (iv) Sky Harbour Addison granted to the Master Trustee a mortgage on its leasehold interest in the real property comprising the ADS Project, (v) OPF Hangars granted the Master Trustee a mortgage on its leasehold interest in the real estate comprising the project located in Opa Locka, Florida, and (vi) Sky Harbour Services LLC, a wholly-owned subsidiary of the Company, has agreed to waive all management fees and development fees during the construction period of the projects associated with the Series 2021 Bonds.

As of March 31, 2023 and December 31, 2022, the fair value of the Company’s Series 2021-1 Bonds was approximately $125.4 million and $119.5 million, respectively. As of March 31, 2023, the fair value of the Company's bonds is estimated utilizing Level 3 inputs, including unobservable inputs reflecting assumptions about the inputs used in pricing the Series 2021-1 Bonds, including using current borrowing rates and trading for debt instruments with similar terms, as there were no trades of the Series 2021-1 Bonds during the three months ended March 31, 2023. As of December 31, 2022, the fair value of the Company’s bonds is estimated utilizing Level 2 inputs including prices for the bonds on inactive markets.

The following table summarizes the Company’s Bonds payable as of March 31, 2023 and December 31, 2022:

Interest

The following table sets forth the details of interest expense:

SHG's legal predecessor, Yellowstone Acquisition Company (“Yellowstone”), issued to third-party investors 6,799,439 warrants which entitled the holder to purchase one share of Class A Common Stock at an exercise price of $11.50 per share (the “Public Warrants”) as part of Yellowstone’s initial public offering. Yellowstone. In addition, Yellowstone sold 7,719,779 private placement warrants (the “Private Placement Warrants”, and together with the Public Warrants, the “Warrants”) to BOC Yellowstone LLC (the “Sponsor”). Each Private Warrant allows the Sponsor to purchase one share of Class A Common Stock at an exercise price of $11.50 per share. The Warrants remain outstanding under the same terms and conditions to purchase shares of the Company’s Class A Common Stock. As of March 31, 2023, 6,799,189 and 7,719,779 Public and Private Warrants remain outstanding, respectively.

The terms of the Private Warrants are identical to those of the Public Warrants, except for that so long as the Private Warrants are held by the Sponsor or its permitted transferees, they may be exercised on a cashless basis. The Warrants contain an exercise price of $11.50 per share and expire on January 25, 2027. The Company determined the fair value of its Public Warrants based on the publicly listed trading price as of the valuation date. Accordingly, the Public Warrants are classified as Level 1 financial instruments. As the terms of the Private Warrants are identical to those of the Public Warrants, the Company determined the fair value of its Private Warrants based on the publicly listed trading price of the Public Warrants as of the valuation date and have classified the Private Warrants as Level 2 financial instruments.

The closing price of the Public Warrants was $0.49 and $0.20 per warrant on March 31, 2023 and December 31, 2022, respectively. The aggregate fair value of the Warrants was approximately $7.1 million and $2.9 million as of March 31, 2023 and December 31, 2022, respectively. The Company recorded unrealized losses of approximately $4.2 million and $13.9 million during the three months ended March 31, 2023 and the three months ended March 31, 2022, respectively.

Common Equity

As of March 31, 2023, there were 15,108,725 and 42,046,356 shares of Class A Common Stock and Class B Common Stock outstanding, respectively. Holders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters submitted to the stockholders for their vote or approval, except as required by applicable law. Holders of Class A Common Stock and Class B Common Stock are entitled to one vote per share on all matters submitted to the stockholders for their vote or approval.

The holders of Class A Common Stock are entitled to receive dividends, as and if declared by the Company’s Board of Directors out of legally available funds. With respect to stock dividends, holders of Class A Common Stock must receive Class A Common Stock. The holders of Class B Common Stock do not have any right to receive dividends other than stock dividends consisting of shares of Class B Common Stock, as applicable, in each case paid proportionally with respect to each outstanding share of Class B Common Stock.

Common Stock Purchase Agreement

On August 18, 2022, the Company entered into a Common Stock Purchase Agreement (the “Stock Purchase Agreement”) with B. Riley Principal Capital II, LLC (“B. Riley”). Pursuant to the Stock Purchase Agreement, subject to the conditions and limitations set forth therein, the Company has the right, but not the obligation, from time to time at the Company's sole discretion over a 36-month term of the Stock Purchase Agreement, to direct B. Riley to purchase up to 10 million shares of the Company's Class A Common Stock in the aggregate.

Under the Stock Purchase Agreement, on any trading day selected by the Company, the Company has the right, in its sole discretion, to present B. Riley with a purchase notice (each, a "VWAP Purchase Notice"), directly B. Riley (as principal) to purchase a specified amount of shares not to exceed the lesser of (i) one million shares of Common Stock and (ii) 20% of the total aggregate number (or volume) of shares of Class A Common Stock traded on the NYSE American at a price(the "VWAP Purchase Price") equal to the product of 0.97 and the VWAP of the Company's Class A Common Stock on the applicable date for each VWAP Purchase Notice, subject to certain limitations contained in the Stock Purchase Agreement. Sales of Class A Common Stock pursuant to the Stock Purchase Agreement, and the timing of any such sales, are solely at the discretion of the Company, and the Company is under no obligation to sell any securities to B. Riley under the Stock Purchase Agreement.

In consideration for entering into the Stock Purchase Agreement and concurrently with the execution of the Stock Purchase Agreement, the Company issued to B. Riley 25,000 shares of Class A Common Stock as initial commitment shares and will issue up to an aggregate of 75,000 shares of its Class A Common Stock as additional commitment shares if certain conditions and milestones are met. As of  March 31, 2023, the Company has not directed B. Riley to purchase any Class A Common Stock pursuant to the Stock Purchase Agreement.

Non-controlling interests

The LLC Interests’ ownership in Sky is presented as non-controlling interests within the Equity section of the consolidated balance sheet as of March 31, 2023 and represents the Sky Common Units held by holders other than SHG. The holders of LLC Interests may exchange Sky Common Units along with an equal number of Class B Common Shares, for Class A Common Shares on the Company. The LLC Interests do not have the option to redeem their Sky Common Units for cash or a variable number of Class A Common Shares, nor does SHG have the option to settle a redemption in such a manner. As of March 31, 2023, the LLC interests owned approximately 73.8% of the Sky Common Units outstanding.

Restricted Stock Units (“RSUs”)

In February 2023, the Company granted time-based RSUs to certain employees under the Company’s 2022 Incentive Award Plan. 545,522 of time-based awards were granted at a grant date fair value of $5.75, which will vest ratably over a four-year period beginning on the first anniversary of the grant date and ending on February 13, 2027.

During the three months ended March 31, 2023 and March 31, 2022, the Company recognized stock compensation expense of $393 and $0, respectively associated with all RSU awards. As of March 31, 2023, there are approximately 1,183,022 non-vested RSUs outstanding with a weighted average grant date fair value of $6.76. The unrecognized compensation costs associated with all unvested RSUs at March 31, 2023 was approximately $6.8 million that is expected to be recognized over a weighted-average future period of 3.5 years.

Sky Incentive Units

The Company recognized equity-based compensation expense relating to awarded equity units of Sky (the “Sky Incentive Units”) of $85 and $86 for the three months ended March 31, 2023, and March 31, 2022, respectively, which is recorded within General and Administrative Expenses within the statement of operations, and as a component of the non-controlling interest in the consolidated statement of changes in stockholders’ equity. As of March 31, 2023, there was $0.6 million of total unrecognized compensation expense that is expected to be recognized over a weighted-average future period of 2.1 years.

Basic earnings (loss) per share of Class A Common Stock is computed by dividing net income (loss) attributable to SHG by the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted net income (loss) per share of Class A Common Stock is computed by dividing net income (loss) attributable to SHG, adjusted for the assumed exchange of all potentially dilutive securities, by the weighted-average number of shares of Class A Common Stock outstanding adjusted to give effect to potentially dilutive shares using the treasury stock method. Shares of the Company’s Class B Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B Common Stock under the two-class method has not been presented. 

Potentially dilutive shares excluded from the weighted-average shares used to calculate the diluted net loss per common share due the the Company's net loss position were as follows:

On September 20, 2021, the Company entered into a non-exclusive agreement with Echo Echo, LLC, a related party to the Founder and CEO, for the use of a Beechcraft Baron G58 aircraft. The effective date of the agreement was September 8, 2021 and the agreement automatically renews annually. The agreement can be terminated without penalty if either party provides 35 days written notice, or if the aircraft is sold or otherwise disposed of. The Company is charged per flight hour of use along with all direct operating costs. Additionally, the Company will also incur the pro rata share of maintenance, overhead and insurance costs of the aircraft. For the three months ended March 31, 2023 and March 31, 2022, the Company recognized $62 and $29 of expense, respectively, within General and administrative expense under the terms of this agreement. The related liability is included in Accounts payable, accrued expenses and other liabilities on the consolidated balance sheet as of March 31, 2023.

For the three months ended March 31, 2023 and March 31, 2022, the Company paid $88 and $20 respectively, for consulting services, to a company that employed the chief financial officer until prior to July 1, 2021.

With respect to the Company’s SGR Phase II project, the Company is subject to requirements that define (i) a minimum improvement amount of $2.0 million and (ii) that related construction commence by October 2023. If these conditions are not met or otherwise waived or amended, the ground lease for the parcels designated for the SGR Phase II project will automatically terminate.

The APA Lease requires the Company to improve the property in accordance with a development plan included in the lease and to complete such improvements within 24-months of the issuance of permitting documents. Construction began on the APA Phase I project in October 2022.

The DVT Lease requires approximately $15.3 million and $14.6 million of improvements to be made for Phase I and for Phase II, if such option is exercised, respectively, within 12-months after receiving permitting documents for each Phase, but in no event later than May 2026. Construction began on the DVT Phase I project in December 2022.

The Company has committed to spend $10.0 million in capital improvements on the ADS construction project. If this amount is not expended, the Company is subject to a reduction of the term of the lease.

The Company has contracts for construction of the APA Phase I and DVT Phase I projects. The Company  may terminate any of the contracts or suspend construction without cause. There are no termination penalties under the APA Phase I or DVT Phase I construction contracts.

Rapidbuilt Acquisition

On May 12, 2023 (the “Option Exercise Date”), Sky exercised the Vendor Purchase Option and acquired a 51% equity interest in Overflow Ltd., a Texas limited partnership (“Overflow”), and its wholly-owned subsidiary, Rapidbuilt, Inc., a Texas corporation (“Rapidbuilt”), for nominal consideration (the “Rapidbuilt Acquisition”). As a result of the Rapidbuilt Acquisition, Weatherford Steel Buildings Holdings LLC, a Delaware limited liability company and wholly-owned subsidiary of Sky (“WSBH”), owns a 50% limited partnership interest in Overflow, and Weatherford Steel Buildings GP LLC, a Delaware limited liability company and wholly-owned subsidiary of Sky (“WSB GP”), owns a 1% general partnership interest in Overflow. 

Rapidbuilt is a manufacturer of pre-engineered steel buildings that previously entered into the Vendor Agreement with Sky. Rapidbuilt and Sky’s strategic partnership has resulted in a standard set of proprietary prototype hangar designs, which are intended to deliver high-quality business aviation facilities, lower construction costs, minimize development risk, expedite permit issuance, and facilitate the implementation of refinements across Sky’s portfolio. 

Guaranty Agreement and Overflow Loan Amendment

In connection with the Rapidbuilt Acquisition, Sky and Vista Bank (the “Lender”) entered into a consent, waiver, and second amendment (the “Loan Amendment”) and a guaranty agreement (the “Guaranty Agreement”) associated with the senior loan agreement between Overflow and Rapidbuilt (collectively, the “Borrowers”), and the Lender (the “Overflow Loan”). Pursuant to the Loan Amendment, (i) the Lender consented to the change in control with respect to the Borrowers; (ii) the Lender waived any pre-existing events of default on the part of the Borrowers; (iii) the Lender agreed to release certain borrowed funds held in reserve, subject to specified terms and conditions; and (iv) the Borrowers agreed to certain reserve enhancement obligations, including the ability to repay principal early at the sole discretion of the Borrowers. Pursuant to the Guaranty Agreement, all of the Borrowers’ obligations under the Overflow Loan will be guaranteed by Sky.

The Overflow Loan was originated in December 2020 between the Borrowers and the Lender and has approximately $10.0 million outstanding as of the Option Exercise Date. The Overflow Loan accrues interest at a per annum rate equal to 3.00% above the three-month secured overnight financing rate published for first day of each calendar quarter by the Federal Reserve Bank of New York. Interest is payable on a monthly basis, and the Borrowers agreed to make certain reserve enhancement payments on January 1, April 1, July 1, and October 1 of each calendar year. The maturity date of the Overflow Loan is December 1, 2025. The Overflow Loan is secured by the (i) accounts, (ii) intellectual property, (iii) equipment, (iv) inventory, (v) vehicles, and (vi) property of the Borrowers, and contains customary affirmative and negative covenants.

Overview and Background

We are an aviation infrastructure development company building the first nationwide network of HBS hangar campuses for business aircraft. We develop, lease, and manage general aviation hangars across the United States, targeting airfields in markets with significant aircraft populations and high hangar demand. Our HBS hangar campuses feature exclusive private hangars and a full suite of dedicated services specifically optimized for home-based, versus transient, aircraft.

The physical footprint of the U.S. business aviation fleet grew by almost 28 million square feet in the ten years preceding the beginning of the COVID-19 pandemic, with hangar supply lagging dramatically, especially in key growth markets. As the fleet of private jets in the United States continues to grow, with recent new aircraft deliveries exceeding retirements, demand for hangar space is at a premium in part because new jets require more square footage of hangar space and the pace of new hangar construction has lagged behind the demand. The cumulative square footage of the business aircraft fleet in the United States increased 50% between 2010 and 2021. Moreover, over that same period, there was an 81% increase in the square footage of larger private jets – those with greater than a 24-foot tail height. A recent study conducted by a business aircraft manufacturer forecasted that business aircraft will only continue to grow in the next ten years, with up to 8,500 new business jet deliveries worth almost $275 billion expected to be delivered between 2023 and 2032, further supported by data from the major business aviation manufacturers that suggest the current order backlog for new business aviation aircraft is almost $47 billion.

These larger footprint aircraft do not fit in much of the existing hangar infrastructure and impose stacking challenges and constraints in the traditional shared or community hangars operated by FBOs. The addition of winglets (the vertical extensions on aircraft wingtips) on most modern business jets inhibits wing-over-wing storage. Aircraft hangars are in high demand and short supply, with some airports compiling waiting lists that can exceed several years.

We believe our scalable, real estate-centric business model is uniquely optimized to capture this market opportunity and address the increased imbalance between the supply and demand for private jet storage. We intend to capitalize on the existing hangar supply constraints at major U.S. airports by targeting high-end tenants in markets where there is a shortage of private and FBO hangar space, or where such hangars are or are becoming obsolete.

We realize economies of scale in construction through a proprietary prototype hangar design replicated at HBS hangar campuses across the United States. This allows for centralized procurement, straightforward permitting processes, efficient development processes, and the best hangar in business aviation. Unlike a service company, our revenues are mostly derived from long-term rental agreements, offering stability and forward visibility of revenues and cash flows. This allows the Company to fund its development through the public bond market, providing capital efficiency and mitigating refinance risk.

With six airport campuses either in development or ongoing operations, the company is targeting fourteen additional airfields in the current growth phase, and an additional 30 in the next.

The table below presents certain information with respect to our portfolio as of March 31, 2023.

PROPERTIES IN OPERATION

PROPERTIES IN DEVELOPMENT

Recent Developments

On January 19, 2023, we amended our existing ground lease agreement with the Town of Addison, TX to include additional parcels of land that will effectively double the land available for development at our ADS HBS hangar campus project.

On February 1, 2023, we substantially completed the construction of our OPF Phase I development project. In connection with the substantial completion of the OPF Phase I hangar campus, tenant leases for certain of our constructed hangars commenced starting in February 2023.

On March 22, 2023, we satisfied the requirements within the Series 2021 Bonds indenture to fund construction costs associated with our ADS Phase I development project with proceeds received from our Series 2021 PABs. See “Note 8 — Bonds payable and interest” in the Notes to Consolidated Financial Statements for additional information regarding the modification of the scope of our Series 2021 Bonds. The approval and exercise of such rights will allow approximately $26 million of proceeds to be used to fund the ADS Phase I development project, and is projected to improve our debt service coverage associated with the Series 2021 Bonds.

On May 12, 2023, we completed the Rapidbuilt Acquisition. We expect this vertical integration will enable us to deliver metal buildings to each development site in shorter timeframes, which we believe will reduce the overall construction duration of each development project

Factors That May Influence Future Results of Operations

Revenues

Our revenues are derived from rents we earn pursuant to the lease agreements we enter into with our tenants. Our ability to expand through new ground leases and tenant leases at airports is integral to our long-term business strategy and requires that we identify and consummate suitable new ground leases or investment opportunities in real estate properties for our portfolio that meet our investment criteria and are compatible with our growth strategy. Our ability to enter into new ground leases and tenant leases on favorable terms, or at all, may be adversely affected by a number of factors. We believe that the business environment of the industry segments in which our tenants operate is generally positive for tenants. However, our existing and potential tenants are subject to economic, regulatory and market conditions that may affect their level of operations and demand for hangar space, which could impact our results of operations. Accordingly, we actively monitor certain key factors, including changes in those factors (fuel prices, new aircraft deliveries, hangar rental rates) that we believe may provide early indications of conditions that may affect the level of demand for new leases and our lease portfolio. See “—Risks Related to our Business and Operations” within the Form 10-K for more information about the risks related to our tenants and our lease payments.

Ground Lease Expense

One of our largest expenses is the lease payments under our ground leases. For the three months ended March 31, 2023 and 2022, our operating lease expense for ground leases was $0.9 million and $1.0 million, respectively. As we enter into new ground leases at new airport sites, our payments to airport landlords will continue to increase into the future. If airport landlords increase the per acre cost of the ground lease of our target campuses, the operating margins at potential target developments may be impacted negatively.

Interest Expense

Economic conditions and actions by policymaking bodies are contributing to rising interest rates, which, along with increases in our borrowing levels, could increase our future borrowing costs. We expect to issue additional debt to finance future site developments and higher interest rates would impact our overall economic performance. In addition, we are subject to credit spreads demanded by fixed income investors. As a non-rated issuer, increases in general of credit spreads in the market, or for us, may result in a higher cost of borrowing in the future. We intend to access the bond market on an opportunistic basis. In addition, we may hedge against rising benchmark interest rates by entering into hedging strategies with high quality counterparties.

General and Administrative Expenses

The general and administrative expenses reflected in our statement of operations are reflective of the professional, legal and consulting fees, payroll costs, and other general and administrative expenses, including those necessary to support our business as a public company such as expenses associated with corporate governance, SEC reporting, and other compliance matters. While we expect that our general and administrative expenses will rise in some measure as our portfolio of campuses grows, we expect that such expenses as a percentage of our portfolio will decrease over time due to efficiencies, economies of scale, insourcing of job functions, and cost control measures.

Construction Material Costs and Labor

When constructing our HBS hangar campuses, we use various materials and components. We generally contract for our materials and labor under guaranteed maximum price contracts upon receipt of building permits. This allows us to mitigate the risks associated with increases in building materials and labor costs between the time construction begins on an HBS hangar campus and the time it is completed. Typically, the materials and most of the components used to construct our HBS hangar campuses are readily available in the United States. In addition, the majority of our materials are supplied to us by our contractors and is included in the price of our contract with such contractors. We continue to monitor the supply markets to achieve the best prices available. Typically, the price changes that most significantly influence our operations are price increases in steel, concrete, and labor. We believe that recent inflationary pressures and market conditions will lead to continued increases in construction costs as well as market rental rates for hangars within our HBS hangar campus development projects. However, there can be no assurance that we will be able to increase the lease rates for the hangars within our HBS hangar campuses to absorb these increased costs and/or delays, if at all.

We intend to continue to aggressively take action to mitigate these inflationary pressures, reduce construction costs, and shorten development schedules, both in the near term at our APA Phase I, DVT Phase I, and ADS Phase I development projects, and in the long term at future projects. We structure our guaranteed maximum price construction contracts with shared savings clauses to incentivize the general contractors to reduce construction costs. At our SGR Phase I and BNA Phase II development projects, our total construction costs were lower than both our original pricing estimate and the project’s contracted guaranteed maximum price.

In July 2022, we entered an exclusive strategic vendor partnership with a metal building and hangar door manufacturer that we expect to result in a reduction in the cost of the metal building and hangar door components at all future HBS hangar campuses. As our strategic partnership grows, we expect this vertical integration will enable us to deliver metal buildings to each development site in shorter timeframes, which we believe will reduce the overall construction duration of each development project. No assurance can be given that our cost mitigation strategies will be successful, the costs of our projects will not exceed budgets or the guaranteed maximum price for such projects, or that the completion will not be delayed beyond the projected completion dates.

Current Capital Requirements and Future Expenditures for Expansion

We previously funded SHC with over $200 million to fund the two phases at each of our five ground leased airport locations. These construction funds and reserves are held at the bondholder trustee.

We maintain the ability to include up to $50 million in new projects outside the original five locations to be funded with a portion of the existing proceeds held by the trustee as long as certain approvals and supplemental consultant reports are provided showing that such new project would result in better coverage of debt service than previously contemplated projects. We exercised this ability utilizing approximately $26 million of the $50 million available and received the requisite approvals and reports in March 2023 with respect to our ADS Phase I development project.

We previously raised equity capital to, along with potential future debt and further equity issuances, begin to fund additional airport campuses and reach up to 20 airport campuses over the next several years. On average, each future campus is anticipated to be composed of an average of 10-20 hangars and is expected to cost approximately $55 million per campus, with 60% or more to be funded with additional public activity bonds. All these future hangar campus projects are discretionary and require us to identify the appropriate airports with the target hangar demand economics, secure required ground leases and permits, and complete future construction at such sites.

The cumulative 20 airport site business plan is estimated to cost approximately $1.2 billion, with approximately 65% to 75% anticipated from long-term private activity bonds and the balance with equity or equity linked financing. Our ability to raise additional equity and/or debt financing will be subject to a number of risks, including our ability to obtain financing upon reasonable terms, if at all, costs of construction, delays in constructing new facilities, operating results, and other risk factors. In the event that we are unable to obtain additional financing, we may be required to raise additional equity capital, creating additional dilution to existing stockholders. There can be no assurance that we would be successful in raising such additional equity capital on favorable terms, if at all.  Even if we can obtain such additional equity financing if needed, there can be no assurance that we would be successful in raising such additional financing on favorable terms, if at all.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following as our critical accounting policies:

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include assumptions used within impairment analyses, estimated useful lives of depreciable assets and amortizable costs, estimates of inputs utilized in determining incentive compensation expense and equity instruments such as warrants, estimates and assumptions related to right-of-use assets and operating lease liabilities. Actual results could differ materially from those estimates.

Cost of Construction

Cost of construction on the consolidated balance sheets is carried at cost. The cost of acquiring an asset includes the costs necessary to bring a capital project to the condition necessary for its intended use. Costs are capitalized once the construction of a specific capital project is probable. Construction labor and other direct costs of construction are capitalized. Professional fees for engineering, procurement, consulting, and other soft costs that are directly identifiable with the project and are considered an incremental direct cost are capitalized. We allocate a portion of our internal salaries to both capitalized cost of construction and to general and administrative expense based on the percentage of time certain employees worked in the related areas. Interest costs on the loans and bonds used to fund the capital projects are also capitalized until the capital project is completed. Once a capital project is complete, the cost of the capital project is reclassified to Constructed Assets on the accompanying balance sheet and we begin to depreciate the constructed asset on a straight-line basis over the lesser of the life of the asset or the remaining term of the related ground lease, including expected renewal terms.

Leases

We account for leases under Accounting Standards Codification (“ASC”) Topic 842, Leases. We determine whether a contract contains a lease at the inception of the contract. ASC Topic 842 requires lessees to recognize operating lease liabilities and right-of-use (“ROU”) assets for all leases with terms of more than 12 months on the consolidated balance sheets. We have made an accounting policy election that will keep leases with an initial term of 12 months or less off our consolidated balance sheets and will result in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. When management determines that it is reasonably certain that we will exercise our options to renew the leases, the renewal terms are included in the lease term and the resulting ROU asset and operating lease liability balances. We have elected to not capitalize any interest cost that is implicit within our operating leases into cost of construction on the consolidated balance sheet, but instead, we expense our ground lease cost in the consolidated statements of operations. 

We have lease agreements with lease and non-lease components; we have elected the accounting policy to not separate lease and non-lease components for all underlying asset classes.

Revenue Recognition

We lease hangar facilities that we construct to third parties. The lease agreements are either on a month-to-month basis or have a defined term and may have options to extend the term. Some of the leases contain options to terminate the lease by either party with given notice. There are no options given to the lessee to purchase the underlying assets. Rental revenue is recognized in accordance with ASC Topic 842, Leases, and includes (i) fixed payments of cash rents, which represents revenue each tenant pays in accordance with the terms of its respective lease and is recognized on a straight-line basis over the term of the lease and (ii) variable payments of tenant reimbursements, which are recoveries of all or a portion of the common area maintenance and operating expenses of the property and are recognized in the same period as the expenses are incurred.

The Company evaluates the collectability of tenant receivables for payments required under the lease agreements. If the Company determines that collectability is not probable, the Company recognizes any difference between revenue amounts recognized to date under ASC 842 and payments that have been collected from the lessee, including security deposit amounts held, as a current period adjustment to rental revenue.

Recent Accounting Pronouncements

See Note 2 — Basis of Presentation and Significant Accounting Policies in the Notes to Consolidated Financial Statements for a full description of recent accounting pronouncements including the expected dates of adoption and effects on results of operations and financial condition.

Results of Operations

Three Months Ended March 31, 2023 Compared to the Three Months Ended March 31, 2022

The following table sets forth a summary of our consolidated results of operations for the periods indicated below and the changes between the periods (in thousands). 

Revenues

Revenues for the three months ended March 31, 2023 were approximately $1.1 million, compared to approximately $0.4 million for the three months ended March 31, 2022. The $0.7 million, or 179%, increase was primarily the result of tenant leases commencing at our OPF hangar campus during the three months ended March 31, 2023, as well as the impact of certain additional tenant leases in place at our SGR and BNA hangar campuses as compared to the three months ended March 31, 2022.

Operating Expenses

Operating expenses increased approximately $0.6 million, or 45%, for the three months ended March 31, 2023, as compared to the three months ended March 31, 2022. The increase reflects higher operating costs associated with the commencement of operations at our BNA and OPF hangar campuses during the three months ended December 31, 2022 and March 31, 2023, respectively. Salaries, wages, and benefits associated with our campus personnel increased by approximately $0.2 million, primarily driven by headcount increases at our BNA and OPF hangar campuses. Other operating expenses increased approximately $0.4 million, primarily driven by increased insurance, property taxes, and utilities associated with operations at our OPF, BNA, and SGR hangar campuses. 

Depreciation Expense

Depreciation increased approximately $0.3 million, or 208%, for the three months ended March 31, 2023, as compared to the three months ended March 31, 2022. The increase reflects the opening of our OPF hangar campus during the three months ended March 31, 2023, the opening of our BNA hangar campus during the three months ended December 31, 2022 and the placement of additional ground support equipment into service throughout 2022 and 2023.

General and Administrative Expenses

For the three months ended March 31, 2023, and 2022, general and administrative expenses were approximately $3.5 million and $4.6 million, respectively. The approximately $1.1 million decrease was primarily due to an approximately $0.8 million decrease in professional fees, which was primarily driven by decreased in legal and accounting related costs due non-recurring transaction costs incurred during the three months ended March 31, 2022, and our efforts to internalize job functions. Marketing and other pursuit costs decreased approximately $0.1 million year-over-year, driven by a reduction in third-party consulting fees, offset by higher travel costs associated with securing airport site acquisitions and potential tenants. Other administrative expenses decreased approximately $0.1 million primarily due to decreased corporate insurance premiums.

Other (Income) Expense

Other (income) expenses decreased from approximately $13.9 million of expense to approximately $4.1 million of expense for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022. This decrease was primarily due to a $9.7 million difference in the mark-to-market adjustment of the outstanding warrants at March 31, 2023 as compared to March 31, 2022.

Liquidity and Capital Resources

Overview

Liquidity is a measure of our ability to meet potential cash requirements, including ongoing commitments to repay borrowings, fund the construction of new assets, fund working capital and other general business needs. Our primary sources of cash include the potential issuance of equity and debt securities and rental payments from tenants. Our long-term liquidity requirements include lease payments under our ground leases with airport authorities, repaying principal and interest on outstanding borrowings, funding the construction costs of our HBS campuses (see “— Construction Material Costs and Labor”), funding for operations, and paying accrued expenses. 

We believe that we have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional private activity bonds and other debt and the issuance of additional equity securities. However, as we have recently become a publicly-traded company, we cannot assure you that we will have access to these sources of capital or that, even if such sources of capital are available, that these sources of capital will be available on favorable terms. Our ability to incur additional debt will depend on multiple factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that are or may be imposed by future lenders. Our ability to access the equity and debt capital markets will depend on multiple factors as well, including general market conditions for real estate companies, our degree of leverage, the trading price of our common stock and debt and market perceptions about our Company.

Our cash deposits may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and the majority are maintained with a major financial institution with reputable credit. Our restricted cash is held in trust at a major financial institution pursuant to the Series 2021 Bonds indenture. We monitor the relative credit standing of financial institutions with whom we transact and limit the amount of credit exposure with any one entity. Our portfolio of investments and restricted investments is composed entirely of U.S. Treasury securities as of March 31, 2023.

The following table summarizes our cash and cash equivalents, restricted cash, investments, and restricted investments as of March 31, 2023 and December 31, 2022 (in thousands):

Common Stock Purchase Agreement

On August 18, 2022, we entered into a Common Stock Purchase Agreement and a Registration Rights Agreement (collectively referred to as the “Purchase Agreement”) with B. Riley Principal Capital, LLC (“B. Riley”). Pursuant to the Purchase Agreement, we have the right, in our sole discretion, to sell to B. Riley up to 10 million shares of our Class A Common Stock at 97% of the volume weighted average price of our Class A Common Stock calculated in accordance with the Purchase Agreement, over a period of 36 months subject to certain limitations and conditions contained in the Purchase Agreement. Sales and timing of any sales of Class A Common Stock are solely at our election, and we are under no obligation to sell any securities to B. Riley under the Purchase Agreement. As consideration for B. Riley’s commitment to purchase shares of our Class A Common Stock, we have issued 25,000 shares of our Class A Common Stock to B. Riley as initial commitment shares and may issue up to an aggregate of 75,000 shares of our Class A Common Stock to B. Riley as additional commitment shares if certain conditions are met.

Equity Financing

On January 25, 2022 (the "Closing Date") we completed the transactions (the "Yellowstone Transaction") contemplated by the Equity Purchase Agreement, dated as of August 1, 2021 (the “Equity Purchase Agreement”), between Yellowstone and Sky. On the Closing Date, Yellowstone changed its name to Sky Harbour Group Corporation, and Sky restructured its capitalization, issuing its Sky Common Units to the Company. As a result of the Yellowstone Transaction, the Sky Common Units that Sky issued to BOC YAC in respect of its Series B Preferred Units were converted into 5,500,000 shares of the Company’s Class A Common Stock and holders of Sky Common Units received one share of the Company’s Class B Common Stock for each Common Unit. As consideration for the issuance of Sky Common Units to the Company, Yellowstone contributed approximately $48 million of net proceeds to us, consisting primarily of the BOC PIPE, and the amount held in the Yellowstone trust account, net of redemptions and transaction costs.

Private Activity Bonds

On September 14, 2021, SHC completed an issuance through the Public Finance Authority (Wisconsin) of $166.3 million of Senior Special Facility Revenue Bonds (Aviation Facilities Project), Series 2021 (the “PABs”). The PABs are comprised of three maturities: $21.1 million bearing interest at 4.00%, due July 1, 2036; $30.4 million bearing interest at 4.00%, due July 1, 2041; and $114.8 million bearing interest at 4.25%, due July 1, 2054. The Series 2021 Bond that has a maturity date of July 1, 2036 was issued at a premium, and Sky received bond proceeds that were $0.2 million above its face value. The net proceeds from the issuance of the PABs proceeds are being used to (a) finance or refinance the construction of various aviation facilities consisting of general aviation aircraft hangars and storage facilities located and to be located on the SGR site, the OPF site, the BNA site, the APA site, and the DVT site; (b) fund debt service and other operating expenses such as ground lease expense during the initial construction period; (c) fund deposits to the Debt Service Reserve Fund; and (d) pay certain costs of issuance related to the PABs.

Debt Covenants

The PABs contain financial and non-financial covenants, including a debt service coverage ratio, a restricted payments test and limitations on the sale, lease, or distribution of assets. To the extent that SHC does not comply with these covenants, an event of default or cross-default may occur under one or more agreements, and we or our subsidiaries may be restricted in our ability to pay dividends, issue new debt or access our leased facilities. The PABs are collateralized on a joint and several basis with the property and revenues of all SHC subsidiaries and their assets financed or to be financed from the proceeds of the PABs.

Covenants in the PABs require SHC to maintain a debt service coverage ratio (as defined in the relevant documents) of at least 1.25 for each applicable test period, commencing with the quarter ending December 31, 2024. The PABs are subject to a Continuing Disclosure Agreement whereby SHC is obligated to provide electronic copies of (i) monthly construction reports, (ii) quarterly reports containing quarterly financial information of SHC and (iii) annual reports containing audited consolidated financial statements of SHC to the Municipal Securities Rulemaking Board. As of March 31, 2023, we were in compliance with all debt covenants.

Cash Flows

Historical Cash Flows

The following table summarizes our sources and uses of cash for the three months ended March 31, 2023 and 2022 (in thousands):

Operating Activities

 Net cash used in operating activities was approximately $4.6 million for the three months ended March 31, 2023, as compared to cash used in operating activities of approximately $10.2 million for the same period in 2022. The $5.6 million decrease in cash used in operating activities was primarily attributable to a $4.0 million favorable change in the Company's working capital position, which was partially driven by a reduction in corporate insurance premiums paid during the three months ended March 31, 2023 as compared to the three months ended March 31, 2022. The decrease was also partially attributable to a $1.6 million decrease in net loss, net of non-cash adjustments. The decrease in net loss was primarily driven by non-recurring general and administrative expenses incurred in the expansion of our business, including transaction-related expenses incurred during the three months ended March 31, 2022.

Investing Activities

Our primary investing activities have consisted of payments related to the cost of construction at our various HBS hangar campus development projects and investment in U.S. Treasury Securities. As our business expands, we expect to continue to invest in our current and anticipated future portfolio of HBS development projects.

 Cash provided by investing activities was approximately $36.3 million for the three months ended March 31, 2023, as compared to cash used in investing activities of approximately $179.0 million for the same period in 2022. The increase of approximately $215.3 million in cash provided by investing activities was driven primarily by the approximately $166.6 million purchase of held-to-maturity U.S. Treasury securities during the three months ended March 31, 2022, as compared to no purchase activity and approximately $40.0 million of proceeds received during the three months ended March 31, 2023. The increase was also attributable to a $3.5 million decrease in payments for costs of construction due to the Company’s ongoing construction projects at OPF, APA, DVT, and ADS, and proceeds of approximately $6.7 million received related to certain of the Company's available for sale investments during the three months ended March 31, 2023.

Financing Activities

Our primary financing activities have consisted of capital raised to fund the growth of our business and proceeds from debt obligations incurred to finance our HBS hangar campus development projects. We expect to raise additional equity capital and issue additional indebtedness as our business grows.

Net cash provided by financing activities was $0 for the three months ended March 31, 2023, as compared to net cash provided by financing activities of approximately $51.9 million for the same period in 2022. The approximately $51.9 million decrease in net cash provided by financing activities was primarily driven by $45.0 million of proceeds received from the issuance of the BOC PIPE and approximately $6.9 million of net proceeds from the Yellowstone trust account, both occurring during the three months ended March 31, 2022 and not recurring during the three months ended March 31, 2023.

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. In pursuing our business and investment objectives, we expect that the primary market risk to which we will be exposed is interest rate risk. Following the issuance of the PABs, all of our indebtedness is now fixed rate debt. However, we may enter into variable rate debt agreements in the future, in which case we intend to hedge against rising benchmark interest rates by entering into hedging strategies with high quality counterparties.
