**SKY HARBOUR GROUP CORPORATION AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS**

**March 31, 2026**

*(in thousands, except share data)*

***1.*** **Organization and Business Operations**

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, 2026*, SHG owned approximately 44.9% of the Sky Common Units and the prior holders of Sky Common Units (the "LLC Interests") owned approximately 55.1% 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").

***2.*** **Basis of Presentation and Summary of Significant Accounting Policies** 

***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 SHG 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, 2025,* 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.

***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 the fair value of 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 is subject to risks and uncertainties common to early-stage companies. For most of its history, the Company has been engaged in securing access to land through ground leases and developing and constructing aviation hangars. The major risks faced by the Company are 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 and increased borrowing costs to the extent that the Company incurs additional indebtedness.

***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, committed bank drawdown facility, and has the ability to utilize its at-the-market offering program 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *7*

***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%, unless otherwise disclosed.

*Cost of Construction* 

Cost of construction on the accompanying 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. Activities associated with internally manufactured hangar buildings, including materials, direct manufacturing labor, and manufacturing overhead directly identifiable with such activities are allocated to our construction projects and 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 projects are 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 estimated useful 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 recognize 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 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 as a component of operating expenses in the consolidated statements of operations.

All of the Company's ground leases at airports 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 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 the *three* months ended *March 31, 2026* and *2025*. 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 *18* — *Commitments and Contingencies*.

*Warrants liability*

The Company accounts for its Warrants (as defined in Note *11* — *Warrants*) 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 Company determines whether a contract contains a lease at the inception of the contract. 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. The Company expects to continue to derive benefit from the underlying assets after the end of the lease term through further leasing arrangements. The underlying assets are the leasehold interest that the Company has in connection with its ground leases. There are *no* options given to the lessee to purchase the underlying assets.

Rental revenue is recognized in accordance with ASC *842* and includes 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. Rental revenue and the corresponding rent and other receivables are recorded net of any concessions and uncollectible tenant receivables, if any, for all periods presented. 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 any additional rent or lease termination fees, as a current period adjustment to rental revenue.

At certain of the Company's hangar campuses, the Company recognizes revenue from ground-based services, such as the fueling and towing of aircraft under ASC Topic *606,* Revenue from Contracts with Customers. Revenue for the sale of aircraft fuel is recognized at the time customer obtains control of the fuel. Revenue for the sale of other ground-based services is recognized at the time the service is performed and provided to customers. Customers are invoiced at the time the services are performed and the associated revenue is recognized in the period it is earned. The Company's fueling arrangements generally are unique at each location it operates, and *may* be accounted for on a gross or net basis. The Company determines whether to recognize fuel and services revenue on a gross or net basis based on consideration of various factors, including whether the Company has control of the products or services prior to delivery to customers, the Company's degree of latitude in establishing the sales price, whether the Company carries the associated inventory risk, and which party is the primary obligor within such sales arrangements.

For the *three* months ended *March 31, 2026* and *2025,* the Company did not derive *10%* of its revenue from any single tenant.

*Income Taxes*

SHG is classified as a corporation for U.S. 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 transactions contemplated by that certain Equity Purchase Agreement, dated as of *August 1, 2021,* by and among Yellowstone Acquisition Company ("YAC") and Sky, which we refer to as 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, 2026* and *2025.* The effective income tax rate for the *three* months ended *March 31, 2026* and *2025* 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 due to the cumulative losses sustained by the Company to date.

***Recently Issued Accounting Pronouncements***

In *November 2024,* the FASB issued ASU *No. 2024*-*03, Income Statement* — *Reporting Comprehensive Income: Expense Disaggregation Disclosures (Subtopic *220*-*40*): Disaggregation of Income Statement Expenses*. This ASU requires public business entities to disclose in the notes to financial statements specific categories within relevant expense captions presented on the face of the income statement. The ASU is effective for annual reporting periods beginning after *December 15, 2026,* and interim reporting periods beginning after *December 15, 2027.* Early adoption is permitted. The amendments should be applied on a prospective basis with retrospective application permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and disclosures.

***3.*** **Investments and Restricted Investments**

Investments of the Company's cash in various U.S. Treasury securities that 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. Investments of the funds held in the restricted trust bank accounts associated with the Series *2021* Bonds and the Series *2026* Bonds, as defined in Note *10* — *Bonds payable, loans payable, and interest*, are reported as "Restricted investments" in the accompanying consolidated balance sheets. Such investments are classified as available-for-sale or held-to-maturity at the time of investment.

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, 2026*. The held-to-maturity restricted investments are carried on the consolidated balance sheet at amortized cost. As of *March 31, 2026*, 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 set forth summaries of the amortized cost, unrealized gains, unrealized losses, and fair value by investment type as of *March 31, 2026* and *December 31, 2025*:

The Company's long-term ground leases have remaining terms ranging between 18 to 71 years, including options for the Company to extend the terms. These leases expire between *2044* 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 addition to the Company's ground leases, the Company has operating leases for ground support vehicles and finance leases for vehicles supporting operations at its pre-engineered metal building subsidiary.

In *January 2026,* the Company, through an indirect, wholly-owned subsidiary of the Company, executed a lease amendment with respect to its ground lease at SWF to add an approximately 10 acre parcel of land to the existing lease (the "SWF Lease Amendment"). The land associated with the SWF Lease Amendment became immediately available for possession in *January 2026* and is co-terminus with the other parcel covered by the Company's ground lease at SWF.

The Company uses derivative financial instruments to manage its interest rate risk associated with its variable-rate term loan facility in an aggregate principal amount of up to $200 million (the "Term Loan Facility") with JPMorgan Chase Bank, N.A. The Company does *not* enter into derivative transactions for speculative or trading purposes. In *October 2025,* the Company entered into an interest rate swap (the "Swap Agreement") for notional amounts of up to $200 million, based on predetermined notional schedule agreement as defined in the Swap Agreement. The Swap Agreement effectively fixes the SOFR component of any loans at or below the notional schedule made under the Term Loan Facility at approximately 2.65%, or 4.73% inclusive of applicable interest rate spreads, for the five-year term.

The following table reflects the fair value of the Swap Agreement as of *March 31, 2026* and *December 31, 2025*:

*Tax-Exempt Series *2026* Bonds Issuance*

On *February 12, 2026,* Sky Harbour Capital III LLC ("Sky Capital III"), an indirect, wholly-owned subsidiary of the Company, completed a $150 million financing through the issuance of Revenue Bonds (Sky Harbour Capital III LLC Aviation Facilities Project), Series *2026* (the "Series *2026* Bonds"). The Series *2026* Bonds were issued by the Public Finance Authority of Wisconsin, a multi-jurisdictional conduit issuer (the "Issuer"), pursuant to a Trust Indenture, dated as of *January 1, 2026 (*the "Indenture") and effective as of *February 12, 2026,* between the Issuer and UMB Bank, N.A., as trustee (the "Series *2026* Bond Trustee"). The proceeds of the Bonds were used to make a loan (the "Loan") to Sky Capital III pursuant to a Loan Agreement, dated as of *February 1, 2026 (*the "Loan Agreement"), between the Issuer and Sky Capital III, and assigned to the Series *2026* Bond Trustee. The Series *2026* Bonds were issued in a limited offering (the "Offering") pursuant to a Limited Offering Memorandum dated *January 29, 2026 (*the "Limited Offering Memorandum") to persons reasonably believed to be qualified institutional buyers pursuant to Rule *144A* under the Securities Act of *1933,* as amended (the "Securities Act") or accredited investors within the meaning of Rule *501*(a) under the Securities Act. The borrowings under the Loan Agreement are guaranteed (the "Guarantee") by Sky, and Sky Harbour Holdings IV LLC, a wholly owned subsidiary of Sky (the "Pledgor"). Pursuant to the Indenture, all of the Issuer's right, title, and interest in the Loan Agreement (except for certain unassigned rights) were assigned to the Series *2026* Bond Trustee. The Series *2026* Bonds are secured by the Loan Agreement and the residual cash flows of certain of the Company's projects, and payment of the Bonds is structurally subordinate to the Series *2021* Bonds and borrowings under the Term Loan Facility.

The Series *2026* Bonds and borrowings under the Loan Agreement bear interest at a rate of 6.00% per year, payable semi-annually in arrears on *January 1* and *July 1* of each year, beginning on *July 1, 2026.* The Series *2026* Bonds are subject to mandatory tender for purchase on *January 1, 2031 (*the "Mandatory Tender Date"), and will mature on *July 1, 2060,* unless earlier exchanged, redeemed or repurchased. On the Mandatory Tender Date, holders will be required to tender their Bonds for purchase at a price equal to 100% of the principal amount thereof plus accrued interest. Following such mandatory tender, the Bonds *may* be remarketed at a new interest rate or otherwise refinanced. Accordingly, although the Series *2026* Bonds have a stated final maturity of *July 1, 2060,* Sky Capital III will be required to refinance or remarket the Series *2026* Bonds on or prior to *January 1, 2031.*

The principal amount of the Loan is $150 million. The Company intends to use the proceeds from the Loan, together with other available funds, including draws from the Company's Term Loan Facility, to (i) finance or refinance, directly or indirectly, all or a portion of the construction, equipping and/or improvement of all or a portion of certain aircraft storage facilities (collectively, the *"2026* Projects"); (ii) fund a deposit to the debt service reserve fund for the Series *2026* Bonds; (iii) pay capitalized interest on the Loan through *January 1, 2029;* and (iv) pay the costs of issuance of the Series *2026* Bonds.

The Series *2026* Bonds are subject to (a) optional redemption at the discretion of Sky Capital III at any time on or after *January 1, 2030* at a redemption price equal to the principal amount plus a *1%* premium and accrued and unpaid interest to the redemption date, (b) mandatory redemption upon the occurrence of a determination of taxability of the Series *2026* Bonds, and (c) mandatory sinking fund redemption beginning in *2056.*

Sky Capital III expects to meet its payment obligations under the Loan Agreement from funds to the extent available and permitted to be released under the master trust indenture with respect to the Series *2021* Bonds and the Term Loan Facility. Interest is capitalized through *January 1, 2029.*

The Indenture and the Loan Agreement provide for customary events of default, all as described in the Indenture and the Loan Agreement.

*Term Loan Facility Amendments*

On *January 8, 2026,* Sky Harbour Capital II LLC ("SH Capital II"), an indirect, wholly-owned subsidiary of the Company, entered into an amendment (the "Amendment") to the Term Loan Facility. The Amendment amended the Term Loan Facility to provide for, among other things, conditions under which surplus funds, as defined in the Amendment (the "Term Loan Facility Surplus Funds"), *may* be released to SH Capital II and its special purpose subsidiaries (the "Term Loan Borrowers"). Also on *January 8, 2026,* subsidiaries of the Company that own existing and future hangar campuses at CMA and BDL were added to the borrowing base of the Term Loan Facility. Subsequently, on *January 8, 2026,* SH Capital II drew funds of approximately $13 million under the Term Loan Facility in order to reimburse the Company for prior advances associated with capital expenditures at Bradley International Airport and certain other general corporate purposes.

In addition, Sky Harbour Holdings III LLC ("SKYH III") amended its related guaranty (the "Sky III Guaranty", and such amendment, the "Sky III Guaranty Amendment") to provide for, among other things, conditions under which surplus funds arising from amounts received by Sky from excess revenues released from the Master Indenture *may* be utilized by Sky, as discussed below.

Provided certain conditions within the Amendment are met, the Amendment permits the Term Loan Borrowers to distribute or otherwise transfer such Term Loan Facility Surplus Funds to (i) Sky (the "Parent Guarantor") for the payment of general and administrative expenses of the Parent Guarantor, (ii) the payment of current interest or principal on indebtedness of the Parent Guarantor or indebtedness guaranteed by the Parent Guarantor, (iii) to deposit or transfer such funds into a separate account of an affiliate of the Parent Guarantor as security for the payment of principal of or interest on other indebtedness, or (iv) as a capital contribution of a Term Loan Borrower for the approved construction and operation of hangar project facilities at various airports (the "Portfolio II Projects", and such restriction on distributions and transfers the "Permissible Uses"). The Amendment permits the release of the Term Loan Facility Surplus Funds beginning on the later of *January 1, 2027* or a trigger date based on substantial completion of certain Portfolio II Projects, and requires the Term Loan Borrowers to maintain (i) a historical debt service coverage ratio, and a (ii) projected debt service coverage ratio, in each case determined on the last day of each fiscal quarter of the Term Loan Borrowers, at a ratio of *not* less than *2.00* to *1.00.*

The Sky III Guaranty Amendment permits the release of excess revenues released from the Master Trust on or after the later of (i) *January 1, 2027* and (ii) *three* (*3*) months after the Capitalized Interest End Date provided that (a) there are funds in excess of $800,000 on deposit in the accounts for such excess revenues on release date, and (b) to the extent there is a deficiency in any of the accounts associated with the Term Loan Facility, there are sufficient funds on deposit (in addition to the minimum amount of funds held pursuant to cover such deficiency) and such funds are applied to remedy each such deficiency. The release of excess revenues is also subject to Permissible Uses.

The above release conditions are also subject to the customary condition that there *not* be any default under the Term Loan Facility.

As of *March 31, 2026,* there was approximately $180.6 million of availability under the Term Loan Facility, subject to borrowing base restrictions.

*2026* Yorkville Promissory Note*

On *January 27, 2026,* Sky issued a non-convertible, unsecured promissory note to YA II PN, Ltd., a Cayman Islands exempt limited company, or its registered assigns ("Yorkville"), in the aggregate principal amount of $10 million (the *"January 2026* Yorkville Promissory Note"). The issue price for the *January 2026* Yorkville Promissory Note was 100% of the aggregate principal amount thereof.

The *January 2026* Yorkville Promissory Note accrues interest at a rate of 7.75% per annum (or 18% upon the occurrence of an event of default) and matures on *June 8, 2027.* Beginning on *July 8, 2026,* and continuing on the same day of each of the *twelve* successive months thereafter, Sky shall repay a portion of the outstanding balance of the *January 2026* Yorkville Promissory Note in an amount equal to $833,333.33. The obligations of Sky under the *January 2026* Yorkville Promissory Note are guaranteed by the Company pursuant to a separate guaranty agreement between the Company and Yorkville. In connection with and pursuant to the *January 2026* Yorkville Promissory Note, the Company issued 40,000 shares of Class A Common Stock to Yorkville. The *January 2026* Yorkville Promissory Note contains customary representations and warranties by Sky and the Company and customary events of default. The proceeds of the *January 2026* Yorkville Promissory Note *may* be used for working capital and general corporate purposes.

***11.*** **Warrants**

SHG's legal predecessor, YAC, 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"). In addition, 7,719,779 private placement warrants were sold 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 Public Warrants and Private Warrants remain outstanding under the same terms and conditions to purchase shares of the Company's Class A Common Stock. 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.

In connection with the Securities Purchase Agreement (the *"2023* Purchase Agreement") entered into on *November 1, 2023* with certain investors, the Company issued to *third*-party investors 1,541,600 warrants (the "PIPE Warrants", and together with the Public Warrants and the Private Warrants, the "Warrants"). The PIPE Warrants are equivalent in form and substance to the Company's Public Warrants.

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 and PIPE Warrants based on the publicly listed trading price as of the valuation date. Accordingly, these 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.

No Warrants were exercised during the *three* months ended *March 31, 2026*. As of *March 31, 2026*, 15,798,155 Warrants remain outstanding.

The closing price of the Warrants was $0.70 and $0.65 per warrant on *March 31, 2026* and *December 31, 2025*, respectively. The aggregate fair value of the outstanding Warrants was approximately $11.1 million and $10.3 million as of *March 31, 2026* and *December 31, 2025*, respectively. During the *three* months ended *March 31, 2026* and *2025,* the Company recorded unrealized losses associated with the change in fair value of the Warrants of approximately $0.8 million and $2.5 million, respectively.

*At-the-Market Facility*

On *March 27, 2024,* the Company entered into an At Market Issuance Sales Agreement (the "ATM Agreement") with B. Riley Securities, Inc. ("B. Riley") with respect to an "at the market" offering program (the "ATM Facility"), under which the Company *may,* from time to time, at its sole discretion, issue and sell through B. Riley, acting as sales agent, up to $100 million of shares of Class A Common Stock. Pursuant to the ATM Agreement, the Company *may* sell the shares through B. Riley by any method permitted that is deemed an "at the market" offering as defined in Rule *415* under the Securities Act of *1933,* as amended. B.

The Company will pay B. Riley a commission of 3.0% of the gross sales price per share sold under the ATM Agreement, subject to certain reductions.

On *December 31, 2025,* the Company entered into an Amended and Restated At Market Issuance Sales Agreement (the "A&R ATM Agreement") with B.

The offering of shares pursuant to the ATM Agreement will terminate upon the earlier to occur of (i) the issuance and sale, through the Sales Agents, of all of the shares subject to the ATM Agreement and (ii) termination of the ATM Agreement in accordance with its terms.

During the *three* months ended *March 31, 2026,* the Company sold 47,371 shares of Class A Common Stock under the ATM Facility at a weighted-average sales price of $10.07.

*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, 2026* 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 of 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, 2026*, the LLC interests owned approximately 55.1% of the Sky Common Units outstanding.

***14.*** **Earnings (loss) per Share**

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 or if-converted method as appropriate. 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.

During the *three* months ended *March 31, 2026* and *2025,* the Company incurred $0 and $3.4 million of construction costs associated with the General Contractor at its APA Phase I project, respectively. The General Contractor was also previously engaged by the Company to serve as an architectural and engineering consultant in connection with its ADS Phase II development project. During the *three* months ended *March 31, 2026* and *2025,* the Company incurred $0 of construction costs associated with such services. All such costs are capitalized and included as a component of cost of construction within the consolidated balance sheet as of *March 31, 2026*.

Ascend shares office space, equipment, and various administrative services with the General Contractor. Costs incurred by the General Contractor are allocated between Ascend and the General Contractor and are charged at cost. During *three* months ended *March 31, 2026* the allocated costs from the General Contractor to Ascend were less than $0.1 million.

***20.*** **Subsequent Events**

On *April 17, 2026,* the subsidiary of the Company that owns a hangar campus at SLC was added to the borrowing base of the Term Loan Facility. Subsequently, the Company drew funds of approximately $14 million under the Term Loan Facility in order to reimburse the Parent for prior advances associated with capital expenditures at SLC and certain other general corporate purposes.

**Overview and Background**

We are an aviation infrastructure development company building the first nationwide network of Home Base Operator ("HBO") campuses designed exclusively for business aircraft. We develop, lease and manage general aviation hangars across the United States, targeting airfields in markets with significant based aircraft populations and high hangar demand. Our HBO campuses feature private and semi-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 46 million square feet in the past sixteen years, 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 taller tail clearances and 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 73% between 2010 and 2025. Moreover, over that same period, there was an 120% 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 over $283 billion expected to be delivered between 2025 and 2034, with over two-thirds of the deliveries expected to be comprised of larger private jets. This forecast is further supported by data from the major business aviation manufacturers that suggest the current order backlog for new business aviation aircraft as of December 31, 2025 is over $57 billion, an increase of approximately 10% over the prior year.

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 fixed-base operators ("FBO"). 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 23

[**Table of Contents**](#toc)

We believe our scalable, real estate-centric business model is uniquely positioned 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 expect to realize economies of scale in construction through prototype hangar designs replicated at our HBO campuses across the United States through our in-house construction management and general contracting. 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 us to fund our development through the public bond market and bank debt, providing capital efficiency and mitigating refinance risk.

We seek to develop our home basing hangar campuses on long-term ground leases (or sub-leases thereof) at airports with suitable infrastructure serving metropolitan centers across the United States. We lease each of our properties under long-term ground leases.

The table below presents certain information with respect to our portfolio of ground leases as of March 31, 2026.

<br> <sup>(1)</sup> <br><sup>Economic Occupancy is measured as the total square footage of aircraft subject to leases divided by the total rentable square footage of the designated property. The square footage of individual aircraft is calculated by multiplying its respective length (i.e., from its nose to its tail) by its wingspan. We believe we can achieve Economic Occupancy in excess of 100% in our semi-private hangars due to stacking considerations and the manner in which we price such semi-private leases. Occupancy and Economic Occupancy are key performance indicators which may be calculated in a manner different than similar key performance indicators used by other issuers. These metrics are estimated operating metrics and not projections, nor actual financial results, and are not indicative of current or future performance.</sup> <br>

**Recent Developments**

In January 2026, we entered into an amendment (the "Amendment") to the Term Loan Facility. The Amendment amended the Term Loan Facility to provide for, among other things, conditions under which surplus funds may be released to us after satisfying Series 2026 Bonds requirements and other release conditions.

In January 2026, we added our subsidiaries that own hangar campuses at CMA and BDL to the borrowing base of the Term Loan Facility. Subsequently, we drew funds of approximately $13 million under the Term Loan Facility in order to reimburse prior advances made by our corporate subsidiary associated with capital expenditures at Bradley International Airport and certain other costs associated with the debt issuance.

In January 2026, we issued a non-convertible, unsecured promissory note to Yorkville, in the aggregate principal amount of $10 million (the "January 2026 Yorkville Promissory Note"). The issue price for the January 2026 Yorkville Promissory Note was 100% of the aggregate principal amount thereof. The January 2026 Yorkville Promissory Note accrues interest at a rate of 7.75% per annum and matures on June 8, 2027.

In February 2026, we completed a $150 million financing through the issuance of the Series 2026 Bonds. The Series 2026 Bonds bear interest at a rate of 6.00% per year, payable semi-annually in arrears on January 1 and July 1 of each year, beginning on July 1, 2026. We intend to use such proceeds, together with other available funds, including draws from the Term Loan Facility, to (i) finance or refinance, directly or indirectly, all or a portion of the construction, equipping and/or improvement of all or a portion of certain aircraft storage facilities (collectively, the "2026 Projects"); (ii) fund a deposit to the debt service reserve fund for the Series 2026 Bonds; (iii) pay capitalized interest on the Series 2026 Bonds; and (iv) pay the costs of issuance of the Series 2026 Bonds.

**Factors That May Influence Future Results of Operations**

***Airfield and Tenant Portfolio Growth***

Our future success depends upon our ability to attract and retain tenants for hangars at our HBO campuses. The extent to which we achieve growth in our customer base materially influences our business and results of operations. Any number of factors could affect our ability to grow our customer base, including tenant preferences for hangar space and related services, including size and location of the hangar, as well as general economic conditions. The level and volatility of fuel prices may also impact the general aviation industry and our ability to attract and retain tenants. For example, during the first quarter of 2026, fuel prices increased significantly as a result of ongoing geopolitical events and market disruptions. At our ADS, APA, and CMA HBO campuses, we are directly exposed to fluctuations in fuel prices, which could have have a material effect on our operating results at such campuses. Due to the competitive nature of our industry, we cannot predict the impact periods of high volatility in fuel prices or significant disruptions in the supply of aircraft fuel will have on our ability to attract and retain tenants. In addition, our ability to attract and retain customers may be dependent on other factors outside of our control, including the future trend of private aircraft sizes and the availability of alternative hangars, including size, location and/or services provided. Any significant decline in our customer base, or in our rate of growth, could have a material adverse effect on our business and results of operations, which could, in turn, result in a decline in the trading price of our securities.

Our ability to expand through new ground leases at airports is also 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 on favorable terms, or at all, may be adversely affected by certain significant factors. We may not be able to negotiate new ground leases with airport authorities on attractive terms or at all, and we may encounter competition from other potential ground lessors, which could significantly increase the lease rate for properties we seek to lease. In our efforts to secure new ground leases, we may incur significant costs and divert management attention in connection with evaluating and negotiating such ground leases, including ground leases that we are subsequently unable to execute. In addition, even if we enter into letters of intent or conditional agreements for new ground leases of airport properties, these agreements are subject to customary closing conditions, including, but not limited to, the satisfactory results of our due diligence investigations and local government and municipal authority approvals.

***Construction Material Costs and Labor***

When constructing our HBO campuses, we use various materials, assemblies, and labor components. We contract for our materials and labor both internally through our in-house general contractor and with various external general contractors under guaranteed maximum price (GMP) contracts upon receipt of building permits. This allows us to mitigate certain inflationary pressures associated with increases in certain building materials and labor costs between the time construction begins at a hangar campus and the time it is completed. Typically, the materials and most of the components used to construct our hangar campuses are readily available in the United States, and we attempt to procure such materials from domestic sources where and when possible. We monitor the supply markets and ensure robust competition to achieve the best prices available. Typically, the price changes that most significantly influence our development operations are price increases in steel, concrete, and labor. Inflationary and supply chain pressures have previously led to increased construction materials costs, specifically associated with steel, concrete, and other materials. Further inflationary and supply chain pressures, including those associated with changes in trade policies, could adversely affect our business. The imposition of or increase in tariffs on construction materials such as steel, and other potential changes in U.S. and global trade policy, could substantially increase the cost of and limit the availability of construction materials. Tariffs and retaliatory tariffs announced by the U.S. and other countries, the implementation, size and timing of which remain uncertain and rapidly evolving, could impact the cost of certain of our construction materials. The implementation of these tariffs and future tariffs, or any changes in trade policies that have a similar effect, or the threat of any of the foregoing, could result in further interruptions in the supply chain. We believe we may continue to experience such pressures in future quarters, as well as delays in our subsidiaries' and contractors' ability to requisition such materials. However, there can be no assurance that we will be able to increase the lease rates for the hangars within our hangar campuses to absorb these increased costs, if at all.

Our projections associated with the commencement and completion of construction, estimated total construction cost, hangars, and rentable square footage of our properties in development are inherently subjective and require judgement to estimate. We believe that our estimates of construction costs and timelines are subject to variability based on various factors including, but not limited to, changes in anticipated site plans, hangar mix, hangar specifications, executed guaranteed maximum price construction contracts, and general market conditions. During 2025, we updated many of our preliminary estimates based on our intention to begin incorporating a larger hangar prototype into our home basing hangar campuses, which is intended to provide an increase in rentable square footage of hangar, office, and lounge space upon completion. This larger hangar prototype requires an increase in construction materials and components, and we expect its incorporation into multiple future development projects will ultimately result in cost savings through the realization of economies of scale. Our updated estimates of total construction costs do not include projections of potential cost reductions due to such efficiencies, and we continue to reevaluate our preliminary and updated estimates from time to time over the course of the development lifecycle. We intend to continue to mitigate inflationary pressures, reduce construction costs to the greatest extent possible, and pursue compressed development schedules. We currently structure our guaranteed maximum price construction contracts with shared savings clauses to incentivize the general contractors to reduce construction costs. No assurance can be given that our cost mitigation strategies will be successful, the costs of our ongoing and future 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.

***Increases in Market Interest Rates and Future Costs of Borrowing***

Economic conditions and actions by policymaking bodies contributed to rising interest rates, which, along with increases in our borrowing levels, could increase our future borrowing costs. While the Federal Reserve reduced interest rates during 2025 and has indicated the potential for further rate cuts in 2026, interest rates remain relatively high and there can be no certainty with respect to the occurrence, timing, or magnitude of further interest rate cuts by the Federal Reserve, and thus no certainty with respect to the ultimate impact on our borrowing costs. We expect to issue additional debt to finance future site developments and refinance the Term Loan Facility and the Series 2026 Bonds on or prior to its maturity date and mandatory tender date, respectively. Elevated 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.

***Current Capital Requirements and Future Expenditures for Expansion***

Each constructed and in-construction facility in our portfolio is funded by secured indebtedness under the Series 2021 Bonds, the Term Loan Facility, or the Series 2026 Bonds. We entered into the $200 million Term Loan Facility in September 2025 and issued $150 million of Series 2026 Bonds in February 2026. We anticipate that the proceeds of the Term Loan Facility and Series 2026 Bonds will fund an additional 1.2 million rentable square feet of construction projects at seven airport locations.

We previously raised equity capital, including the 2024 Purchase Agreement and 2023 Purchase Agreement entered into on September 16, 2024 and November 1, 2023, respectively, see *Liquidity and Capital Resources* — *Private Placement and Securities Purchase Agreement* below, to begin to fund construction at additional HBO campuses over the next several years. We also have the ability to access the capital markets through our ATM Facility and through our effective shelf registration statement on Form S-3. On average, each future campus is anticipated to be composed of 200,000 rentable square feet and is expected to cost approximately $60 million, with 70% or more to be funded with additional private activity bonds or other indebtedness. All 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 50 airport site business plan is estimated to cost approximately $3.0 billion, with approximately 80% or more anticipated from 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, our ability to reinvest free cash flow from operations, 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.

**Key Business Metrics**

We focus on a variety of indicators and key operating and financial metrics to monitor the financial condition and performance of the continuing operations of our business. These metrics include:

---

| | |
|:---|:---|
| **Metric** | **Description** |
| ***Revenue*** | The majority of our revenue is generated from rents and fees we earn pursuant to the lease and service agreements we enter into with our tenants. Our ability to achieve revenue growth depends upon our ability to attract and retain tenants for hangars at our home basing hangar campuses. The extent to which we achieve growth in our customer base materially influences our business and results of operations. Any number of factors could affect our ability to grow our customer base, including tenant preferences for hangar space and related services, including size and location of the hangar, as well as general economic conditions. 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. We derive all of our revenue from tenants in the United States. At certain of our HBO campuses, we recognize revenue from ground-based services, such as the fueling and towing of aircraft. Revenue for the sale of aircraft fuel is recognized at the time customer obtains control of the fuel. Revenue for the sale of other ground-based services is recognized at the time the service is performed and provided to customers. Customers are invoiced at the time the services are performed and the associated revenue is recognized in the period it is earned. Our fueling arrangements generally are unique at each location we operate, and may be accounted for on a gross or net basis. We determine whether to recognize fuel and services revenue on a gross or net basis based on consideration of various factors, including whether we have control of the products or services prior to delivery to customers, our degree of latitude in establishing the sales price, whether we carry the associated inventory risk, and which party is the primary obligor within such sales arrangements. |
| ***Operating Expenses*** | In addition to changes in our revenue, our operating results are affected by, among other things, the level of our operating expenses. One of our largest expenses is the payments payable under our ground leases. For the three months ended March 31, 2026 and 2025, we recognized expense related to ground leases of approximately $4.0 million and $2.9 million, respectively. We elect to expense rather than capitalize ground lease expense incurred at hangar campus sites under development and will incur expense under GAAP regardless of whether our ground leases defer cash rent payments until completion of construction. As we enter into new ground leases at new airport sites, our ground lease expense and associated cash payments to airport landlords will ultimately 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. Other operating expenses reflected in our consolidated statement of operations are reflective of the professional, legal and consulting fees, compensation 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 such expenses will rise in some measure as our portfolio of hangar 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. |
| ***Operating Income (Loss)*** | The presentation of operating income (loss) provides a measure of performance which is useful for investors, analysts and other interested parties in company-to-company operating performance comparisons. Operating income (loss) is computed by deducting operating expenses from revenue. |
| ***Net Income (Loss)*** | The presentation of net income provides a measure of performance which is useful for investors, analysts and other interested parties in company-to-company operating performance comparisons.  |
| ***Adjusted EBITDA*** | We utilize Adjusted EBITDA to evaluate our operating and financial performance, which is supplemental in nature and a financial measure not calculated in accordance with GAAP. We define Adjusted EBITDA as net income before (i) depreciation and amortization expense, (ii) interest expense, (iii) interest income, (iv) non-cash stock-based compensation expense, (v) non-cash gains and losses resulting from the change in fair value of our liability-classified warrants, (vi) non-cash operating lease expense, (vii) non-cash operating lease income, (viii) provision for income taxes, (ix) other non-cash expenses, including, but not limited to, the impairment of long-lived assets, gains or losses arising from the disposition of assets, losses on extinguishment of debt, and other non-cash non-operating expenses. We believe Adjusted EBITDA is useful for investors, analysts and other interested parties as it provides a view of our operating performance, analyzes our ability to meet debt service obligations, and facilitates company-to-company operating performance comparisons by excluding potential differences caused by variations in capital structures, the age and book depreciation of assets, and equity-based incentive plans. Our method of calculating Adjusted EBITDA may differ from that utilized by other companies and therefore its comparability may be limited. See the section titled "Non-GAAP Financial Measures" below for more information and reconciliations to the most directly comparable GAAP financial measure. |
| ***Net Cash Provided By (Used In) Operating Activities*** | We focus on measures designed to monitor cash flow, including net cash provided by (used in) operating activities. The presentation of net cash provided by (used in) operating activities provides a measure of performance which is useful for investors, analysts and other interested parties in company-to-company operating performance comparisons.  |

**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 the fair value of 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.

*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 any additional rent or lease termination fees, as a current period adjustment to rental revenue.

At certain of our HBO campuses, we recognize revenue from ground-based services, such as the fueling and towing of aircraft. Revenue for the sale of aircraft fuel is recognized at the time customer obtains control of the fuel. Revenue for the sale of other ground-based services is recognized at the time the service is performed and provided to customers. Customers are invoiced at the time the services are performed and the associated revenue is recognized in the period it is earned. Our fueling arrangements generally are unique at each location we operate, and may be accounted for on a gross or net basis. We determine whether to recognize fuel and services revenue on a gross or net basis based on consideration of various factors, including whether we have control of the products or services prior to delivery to customers, our degree of latitude in establishing the sales price, whether we carry the associated inventory risk, and which party is the primary obligor within such sales arrangements.

***Revenues***

Rental revenues for the three months ended March 31, 2026 were approximately $6.5 million, compared to approximately $4.5 million for the three months ended March 31, 2025. The $2.0 million, or 46%, increase was primarily the result of operations at our DVT, APA, and ADS hangar campuses, which commenced operations throughout the year ended December 31, 2025, and the cumulative impact of increased occupancy at our BNA, OPF, and SJC hangar campuses.

Fuel revenues for the three months ended March 31, 2026 were approximately $2.2 million, compared to approximately $1.1 million for the three months ended March 31, 2025. The approximately $1.1 million, or 97%, increase was primarily the result of a $0.8 million increase in fuel sales at our CMA, ADS, and APA hangar campuses, where our fuel revenues and related expenses are recognized on a gross basis. Other fuel revenue increased by approximately $0.3 million, which was primarily driven by an increase in fuel gallons uplifted at our BNA, OPF, and SJC hangar campuses due to increased occupancy.

***Operating Expenses***

Campus operating expenses increased approximately $0.7 million, or 37%, from approximately $1.9 million for the three months ended March 31, 2025, to approximately $2.6 million for the three months ended March 31, 2026. Salaries, wages, and benefits associated with our hangar campus personnel increased approximately $0.2 million, primarily driven by headcount increases associated with the commencement of operations at our DVT, APA, and ADS hangar campuses throughout the year ended December 31, 2025. Other campus operating expenses increased approximately $0.5 million, primarily driven by increased insurance, property taxes, and utilities associated with operations at DVT, APA, and ADS.

Fuel expenses for the three months ended March 31, 2026 were approximately $1.1 million, compared to approximately $0.7 million for the three months ended March 31, 2025. The approximately $0.4 million, or 57%, increase was primarily the result of an increase in the cost of fuel of approximately $0.4 million, driven by the impact of recognizing fuel revenue and expenses on a gross basis at our CMA, ADS, and APA hangar campuses.

Ground lease expenses increased approximately $1.1 million, or 36%, from approximately $2.9 million for the three months ended March 31, 2025, to approximately $4.0 million for the three months ended March 31, 2026. The increase in ground lease expense was driven by the ground leases signed at the ground leases signed at SWF and HIO during the three months ended June 30, 2025 and the ground leases signed at LGB and FTW during the three months ended December 31, 2025.

Depreciation and amortization for the three months ended March 31, 2026 was approximately $2.0 million, as compared to approximately $1.1 million for the three months ended March 31, 2025. The approximately $0.9 million, or 79%, increase was primarily driven by the commencement of operations at our DVT and ADS campuses during the three months ended June 30, 2025, and the commencement of operations at our APA campus during the three months ended September 30, 2025.

***Operating Expenses - Continued***

Pursuit and marketing expenses for the three months ended March 31, 2026 were approximately $0.6 million, compared to approximately $0.6 million for the three months ended March 31, 2025. The 7% increase was primarily the result of increased marketing spend and our investment in our growth strategy in securing airport site acquisitions and potential tenants throughout the year.

Employee compensation and benefits expenses increased approximately $0.1 million, or 3%, to $4.3 million for the three months ended March 31, 2026, as compared to approximately $4.2 million for the three months ended March 31, 2025. The increase was primarily driven by an increase in expense recognized associated with our equity compensation programs.

For the three months ended March 31, 2026 and 2025, other general and administrative expenses were approximately $1.1 million and approximately $1.0 million, respectively. The approximately $0.1 million, or 11%, increase was primarily driven by increases in professional fees and technology costs due to the expansion of the business and headcount, offset by a slight decrease in corporate insurance premiums.

***Other (Income) Expense***

Other expense decreased from approximately $2.3 million for the three months ended March 31, 2025, to approximately $2.0 million for the three months ended March 31, 2026. The decrease was primarily due to an approximately $1.7 million difference in the mark-to-market adjustment of the outstanding warrants at March 31, 2026 as compared to March 31, 2025 offset by an approximately $1.2 million increase in interest expense due to higher indebtedness and an approximately $0.3 million decrease in interest income.

**Non-GAAP Financial Measures**

To supplement our results presented in accordance with GAAP, we utilize Adjusted EBITDA, a non-GAAP financial measure that excludes or adjusts certain items. We define Adjusted EBITDA as net income before (i) depreciation and amortization expense, (ii) interest expense, net of capitalized interest, (iii) interest income and realized gains from available-for-sale securities, (iv) non-cash stock-based compensation expense, (v) non-cash unrealized gains and losses resulting from the change in fair value of our liability-classified warrants, (vi) non-cash operating lease expense, (vii) non-cash operating lease income, (viii) provision for income taxes, (ix) other non-cash expenses, including, but not limited to, the impairment of long-lived assets, gains or losses arising from the disposition of assets, losses on extinguishment of debt, and other non-cash non-operating expenses.

Management uses Adjusted EBITDA to facilitate operating performance comparisons from period to period. We believe this non-GAAP financial measure provides investors, analysts, and other interested parties useful information to evaluate our business performance as the removal of certain non-cash expenses and income facilitates company-to-company operating performance comparisons. While we believe this non-GAAP financial measure is useful in evaluating our business, it should be considered as supplemental in nature and is not meant to be considered in isolation or as a substitute for the related financial information prepared in accordance with GAAP. In addition, this non-GAAP financial measures may not be the same as a similarly entitled measure reported by other companies, limiting their usefulness as comparative measures. See below for a reconciliation of net income (loss) to Adjusted EBITDA, as well as "Key Business Metrics" for further discussion of Adjusted EBITDA.

**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 hangar campus development projects (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, drawdowns under the Term Loan Facility, and other debt and the issuance of additional equity securities. We also have the ability to utilize our ATM Facility or otherwise utilize our shelf registration statement on Form S-3 to access the capital markets. However, 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 us.

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, 2026.

The following table summarizes our cash and cash equivalents, restricted cash, investments, and restricted investments as of March 31, 2026 and December 31, 2025 (in thousands):

---

| | | |
|:---|:---|:---|
|  | **March 31, 2026** | **December 31, 2025** |

***Private Activity Bonds***

*Series 2026 Bonds*

On February 12, 2026, Sky Harbour Capital III LLC ("Sky Capital III") completed a $150 million financing through the issuance of Series 2026 Bonds. The Series 2026 Bonds were issued by the Public Finance Authority of Wisconsin and bear interest at a rate of 6.00% per year, payable semi-annually in arrears on January 1 and July 1 of each year, beginning on July 1, 2026. The Series 2026 Bonds are subject to mandatory tender for purchase on January 1, 2031 (the "Mandatory Tender Date"), and will mature on July 1, 2060, unless earlier exchanged, redeemed or repurchased. On the Mandatory Tender Date, holders will be required to tender their Bonds for purchase at a price equal to 100% of the principal amount thereof plus accrued interest. Following such mandatory tender, the Series 2026 Bonds may be remarketed at a new interest rate or otherwise refinanced. Accordingly, although the Series 2026 Bonds have a stated final maturity of July 1, 2060, Sky Capital III will be required to refinance or remarket the Series 2026 Bonds on or prior to January 1, 2031. We intend to use the proceeds, together with other available funds, including draws from the Company's Term Loan Facility, to (i) finance or refinance, directly or indirectly, all or a portion of the construction, equipping and/or improvement of all or a portion of the 2026 Projects; (ii) fund a deposit to the debt service reserve fund for the Series 2026 Bonds; (iii) pay capitalized interest on the Series 2026 Bonds through January 1, 2029; and (iv) pay the costs of issuance of the Series 2026 Bonds.

*Series 2021 Bonds*

On September 14, 2021, SHC completed an issuance through the Public Finance Authority (Wisconsin) of $166.3 million of Series 2021 PABs. The Series 2021 Bonds 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 Series 2021 Bonds proceeds were 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, the DVT site, and following our March 2023 election to reallocate a portion of the net proceeds, the ADS 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 Series 2021 Bonds.

***Term Loan Facility***

On September 4, 2025, we entered into a Draw Down Note Purchase And Continuing Covenant Agreement (the "Credit Agreement") among SH Capital II, the other borrowers party thereto, the lenders party thereto (the "Lenders") and JPMorgan Chase Bank, N.A., as administrative agent, sole bookrunner and sole lead arranger ("JPMorgan" or "Administrative Agent"). The Credit Agreement provides for, among other things, the Term Loan Facility. The Term Loan Facility provides for borrowings up to an aggregate principal amount of $200 million under the Credit Agreement (the "Loans") to be made by the Lenders from time to time as requested by SH Capital II. The Loans will mature on September 4, 2030, subject to any extensions by the Lenders. The Term Loan Facility may be increased, subject to credit approval, up to an aggregate principal amount of $300 million. Such Loans will bear interest at a rate of 80% of the sum of SOFR and 0.10%, plus 200 basis points. In October 2025, we entered into an interest rate swap (the "Swap Agreement") for notional amounts of up to $200 million, based on predetermined notional schedule agreement as defined in the Swap Agreement. The Swap Agreement effectively fixes the SOFR component of any Loans at or below the notional schedule made under the Term Loan Facility at approximately 2.65%, or 4.73% inclusive of applicable interest rate spreads, for the five-year term.

The Credit Agreement provides for Loans to be made from time to time by our special purpose subsidiaries of SH Capital II for the construction and operation of hangar project facilities at various airports (the "Hangar Projects"), subject to customary phased eligibility criteria. Loans will be secured by the real estate underlying the Hangar Projects, pledges of equity interests and certain revenues of SH Capital II and the special purpose subsidiaries (the "Term Loan Borrowers"). Sky and Sky Harbour Holdings II LLC, the holding company of SH Capital II, and Sky Harbour Holdings III LLC will guarantee the Term Loan Borrower's obligations under the Loans pursuant to a Parent Guarantee and a Holdco Guaranty, respectively. In addition, pursuant to a Non-Recourse Carveout Guaranty, we will be required to guarantee the Term Loan Borrowers' obligations under the Loans in certain limited circumstances such as misconduct by the Term Loan Borrowers or the primary guarantors.

The issue price for the January 2026 Yorkville Promissory Note was 100% of the aggregate principal amount thereof. The January 2026 Yorkville Promissory Note accrues interest at a rate of 7.75% per annum (or 18% upon the occurrence of an event of default) and matures on June 8, 2027. Beginning on July 8, 2026, and continuing on the same day of each of the twelve successive months thereafter, we will be required to repay a portion of the outstanding balance of the January 2026 Yorkville Promissory Note in an amounts equal to approximately $0.8 million.

***Private Placement and Securities Purchase Agreements***

*2024 Private Placement and Securities Purchase Agreement*

On September 16, 2024, we entered into a Securities Purchase Agreement (the "2024 Purchase Agreement") with certain investors (collectively, the "Initial 2024 Investors") relating to, among other things, the issuance and sale to the Initial 2024 Investors at an initial closing an aggregate of 3,352,106 shares (the "Initial 2024 PIPE Shares") of our Class A Common Stock for an aggregate purchase price of $31.8 million, and agreed to sell and issue to the Initial 2024 Investors at a second closing, at the option of the Initial 2024 Investors, up to an aggregate of number of shares equal to the number of each such Initial 2024 Investor's Initial 2024 PIPE Shares purchased in the Initial 2024 Closing at the same purchase price of $9.50 per share (the "Second 2024 Closing" and, together with the Initial Closing, the "2024 Financing"). On October 25, 2024, additional investors (the "Additional 2024 Investors" and, together with the Initial 2024 Investors, the "2024 Investors") each executed a joinder to the 2024 Purchase Agreement, pursuant to which the Additional 2024 Investors agreed to purchase, and we agreed to sell, an aggregate of 603,684 additional shares of Class A Common Stock (the "Additional 2024 PIPE Shares", and together with the Initial 2024 PIPE Shares, the "First Closing 2024 PIPE Shares") for an aggregate purchase price of $5.7 million. The initial closing under the 2024 Purchase Agreement occurred on October 25, 2024 (the "Initial 2024 Closing"), and 3,955,790 First Closing 2024 PIPE Shares were issued to the Investors for an aggregate purchase price of $37.6 million. In December 2024, we sold and issued to the 2024 Investors an aggregate of 3,955,790 Second Closing 2024 PIPE Shares for an aggregate purchase price of approximately $37.6 million (the "Second 2024 Closing"). Inclusive of the Initial 2024 Closing, we issued and sold an aggregate of 7,911,580 shares of Class A Common Stock for an aggregate purchase price of approximately $75.2 million. See "Note 13 — *Equity*" in the Notes to Consolidated Financial Statements for additional information regarding the 2024 Purchase Agreement.

*2023 Private Placement and Securities Purchase Agreement*

On November 1, 2023, we entered into a Securities Purchase Agreement (the "2023 Purchase Agreement") with certain investors (collectively, the "2023 Investors"), pursuant to which we sold and issued to the 2023 Investors at an initial closing an aggregate of 6,586,154 shares of our Class A Common Stock (the "Initial 2023 PIPE Shares") and accompanying warrants to purchase up to 1,141,600 shares of Class A Common Stock (the "Initial PIPE Warrants"), for an aggregate purchase price of $42.8 million (the "Initial 2023 Financing"). On November 29, 2023, pursuant to the terms of the 2023 Purchase Agreement, we sold and issued to the 2023 Investors an aggregate of 2,307,692 shares of our Class A Common Stock (the "2023 Additional PIPE Shares" and, together with the 2023 Initial PIPE Shares, the "2023 PIPE Shares") and accompanying warrants to purchase an aggregate of 400,000 shares of Class A Common Stock (the "Additional PIPE Warrants" and, together with the Initial PIPE Warrants, the "PIPE Warrants") for an aggregate purchase price of $15.0 million. The aggregate PIPE financing through the 2023 Purchase Agreement totaled approximately $57.8 million, or $6.50 per share.

***At-the-Market Facility***

On March 27, 2024, we entered into an At Market Issuance Sales Agreement (the "ATM Agreement") with B. Riley Securities, Inc. ("B. Riley") with respect to an "at the market" offering program (the "ATM Facility"), under which we may, from time to time, at our sole discretion, issue and sell through B. Riley, acting as sales agent, up to $100 million of shares of Class A Common Stock. Pursuant to the ATM Agreement, we may sell the shares through B. Riley by any method permitted that is deemed an "at the market" offering as defined in Rule 415 under the Securities Act. B. Riley will use commercially reasonable efforts consistent with its normal trading and sales practices to sell the shares from time to time, based upon instructions from us, including any price or size limits or other customary parameters or conditions we may impose. We pay B. Riley a commission of 3.0% of the gross sales price per share sold under the ATM Agreement, subject to certain reductions. On December 31, 2025, we entered into an Amended and Restated At Market Issuance Sales Agreement (the "A&R ATM Agreement") with B. Riley and Yorkville Securities, LLC ("Yorkville Securities" and, together with B. Riley, the "Sales Agents"), pursuant to which, among other things, Yorkville Securities was added as an additional sales agent. Pursuant to the A&R ATM Agreement, we may offer and sell, from time to time through the Sales Agents, shares of its Class A Common Stock, having an aggregate offering price of up to $100.0 million (the "ATM Shares"). The material terms and conditions of the ATM Agreement otherwise remain unchanged.

During the three months ended March 31, 2026, the Company sold 47,371 shares of Class A Common Stock under the ATM Facility at a weighted-average sales price of $10.07. As of March 31, 2026, ATM Shares having an aggregate gross sales price of up to approximately $97.3 million remain available for issuance under the A&R ATM Agreement.

We are not obligated to sell any shares under the A&R ATM Agreement. The offering of shares pursuant to the A&R ATM Agreement will terminate upon the earlier to occur of (i) the issuance and sale, through the Sales Agents, of all of the shares subject to the A&R ATM Agreement and (ii) termination of the A&R ATM Agreement in accordance with its terms. We have made limited sales under the ATM Facility to date and will only do so when our stock price is at prices our Board deems appropriate.

***Debt Covenants***

The Term Loan Facility contains financial and non-financial covenants, including a debt service coverage ratio, debt service reserve requirements, restricted payments test, and limitations on the sale, lease, or distribution of assets. Commencing three months after the earlier of September 4, 2028 or a trigger date based on substantial completion of certain projects, SH Capital II is required to maintain a historical and projected debt service coverage ratio of no less than 1.25 to 1.00.

The Series 2021 Bonds 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 Series 2021 Bonds 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 Series 2021 Bonds. Covenants in the Series 2021 Bonds 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 Series 2021 Bonds 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, 2026, we were in compliance with all debt covenants.

**Cash Flows**

The following table summarizes our sources and uses of cash for the three months ended March 31, 2026 and 2025 (in thousands):

---

| | | |
|:---|:---|:---|
|  | **Three months ended** | **Three months ended** |
|  | **March 31, 2026** | **March 31, 2025** |
| Cash and restricted cash at beginning of period | $37024 | $94359 |
| Net cash used in operating activities | (3918) | (5050) |
| Net cash used in investing activities | (126933) | (4497) |
| Net cash provided by (used in) financing activities | 174910 | (1162) |
| Cash and restricted cash at end of period | $81083 | $83650 |

---

*Operating Activities*

Cash used in operating activities is significantly influenced by the amount of cash we invest in personnel and infrastructure to support the anticipated growth of our business. Our working capital consists primarily of cash, receivables from tenants, prepaid expenses, accounts payable, accrued compensation, accrued other expenses, and lease liabilities. The timing of collection of our tenant receivables, and the timing of spending commitments and payments of our accounts payable, accrued expenses, accrued payroll and related benefits, all affect these account balances.

Net cash used in operating activities was approximately $3.9 million for the three months ended March 31, 2026, as compared to cash used in operating activities of approximately $5.1 million for the same period in 2025. The approximately $1.1 million decrease in cash used in operating activities was primarily attributable to an approximately $1.2 million decrease in net loss, net of non-cash adjustments, offset by an unfavorable change in working capital of approximately $0.1 million. The decrease in net loss, net of non-cash adjustments was primarily driven by the impact of increases in revenue from our operations at DVT, APA, and ADS. The unfavorable change in working capital was primarily driven by the timing of collections of accounts receivable as well as spending commitments and payments of our accounts payable and other accrued expenses.

*Investing Activities*

Our primary investing activities have consisted of payments related to the cost of construction at our various 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 hangar campus development projects.

Net cash used in investing activities was approximately $126.9 million for the three months ended March 31, 2026, as compared to cash used in investing activities of approximately $4.5 million for the same period in 2025. The increase of approximately $122.4 million of cash used in investing activities was driven primarily by an increase in purchases of available-for-sale and held-to-maturity securities of $63.9 million due to the investment of certain Series 2026 Bonds proceeds, a decrease in proceeds received from available-for-sale investments of approximately $49.9 million, and an increase of capital expenditures of approximately $8.4 million.

*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 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 approximately $174.9 million for the three months ended March 31, 2026, as compared to net cash used in financing activities of approximately $1.2 million for the same period in 2025. The approximately $176.1 million increase in net cash used in financing activities was primarily driven by proceeds received from the issuance of the Series 2026 Bonds of $150.0 million and approximately $29.0 million of proceeds received from the Term Loan Facility and 2026 Yorkville Promissory Note. These were offset by an increase of $3.9 million in payments for debt issuance costs.
