**SKY HARBOUR GROUP CORPORATION AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS**

**June 30, 2025**

*(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 *June 30, 2025*, SHG owned approximately 44.6% of the Sky Common Units and the prior holders of Sky Common Units (the "LLC Interests") owned approximately 55.4% 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, 2024,* 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. Amounts previously presented as rental revenue are now separately disclosed as rental revenue and fuel revenue within the consolidated statement of operations. Amounts previously presented as operating expenses are now separately disclosed as campus operating expenses, fuel expenses, and ground lease expenses within the consolidated statement of operations. Amounts previously presented as general and administrative expenses are now separately disclosed as pursuit and marketing expenses, compensation and benefits, and general and administrative expenses within the consolidated statement of operations. These reclassifications had *no* effect on total revenue, total expenses, net loss, net loss per common share and had *no* impact on the Company's consolidated balance sheets, statement of stockholders' equity and statement of cash flows for the prior year period.

***Use of Estimates***

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

***Risks and Uncertainties***

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

***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 project is completed.

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

*Leases*

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

The Company 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.

*Warrants liability*

The Company accounts for its Warrants (as defined in Note *9* — *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *8*

*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.

Variable payments consist of tenant reimbursements for common area maintenance, utilities, and operating expenses of the property, and various other fees, including fees associated with the delivery of aircraft fuel, late fees, and lease termination fees. Variable payments are charged based on the terms and conditions included in the respective tenant leases and are recognized in the same period as the expenses are incurred.

The table below sets forth a summary of variable payments for the *three* and *six* months ended *June 30, 2025* and *2024* recorded in the captions within our consolidated statement of operations:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Three months ended** | **Three months ended** | **Six months ended** | **Six months ended** |
|  | **June 30, 2025** | **June 30, 2024** | **June 30, 2025** | **June 30, 2024** |
| Variable payments included in rental revenue | $411 | $229 | $736 | $343 |
| Variable payments included in fuel revenue | 616 | 444 | 1145 | 710 |
| Total variable payments included in revenue | $1027 | $673 | $1881 | $1053 |

---

As of *June 30, 2025* and *December 31, 2024*, the deferred rent receivable included in accounts receivable, prepaid expenses, and other assets was $960 and $594, respectively. Rent received in advance represents tenant payments received prior to the contractual due date, and is included in accounts payable, accrued expenses, and other liabilities. Rent received in advance consisted of $441 and $390 as of *June 30, 2025* and *December 31, 2024*, respectively.

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* and *six* months ended *June 30, 2025* and the *three* and *six* months ended *June 30, 2024*, 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* and *six* months ended *June 30, 2025* and *2024.* The effective income tax rate for the *three* and *six* months ended *June 30, 2025* and *2024* 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 *December 2023,* the FASB issued ASU *No. 2023*-*09, Income Taxes (Topic *740*): Improvements to Income Tax Disclosures*. The amendments in this update apply to all entities that are subject to Topic *740,* Income Taxes. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The amendments in this update are effective for annual periods beginning after *December 15, 2024.* The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact of this updated standard on its disclosures to the consolidated financial statements.

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 have been classified as available-for-sale and are carried at estimated fair value utilizing Level *1* inputs as determined based upon quoted market prices.

Pursuant to provisions within the Master Indenture of the Series *2021* Bonds, as defined in Note *8* — *Bonds payable, loans payable, and interest*, the Company invests the funds held in the restricted trust bank accounts in various U.S. Treasury securities. Therefore, such investments are reported as "Restricted investments" in the accompanying consolidated balance sheets. Unrealized losses on certain of the Company's investments and restricted investments are primarily attributable to changes in interest rates. The Company does *not* believe the unrealized losses represent impairments because the unrealized losses are due to general market factors. The Company has not recognized an allowance for expected credit losses related to its investments or restricted investments as the Company has not identified any unrealized losses attributable to credit factors during the *three* and *six* months ended *June 30, 2025*. The held-to-maturity restricted investments are carried on the consolidated balance sheet at amortized cost. As of *June 30, 2025*, 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 *June 30, 2025* and *December 31, 2024*:

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. In addition to the Company's ground leases, the Company has operating leases for office space and ground support vehicles, and finance leases for vehicles supporting operations at our pre-engineered metal building subsidiary.

The Company's lease population does *not* include any residual value guarantees. The Company has operating leases that contain variable payments, most commonly in the form of common area maintenance and operating expense charges, which are based on actual costs incurred. These variable payments were excluded from the calculation of the ROU asset and operating lease liability balances since they are *not* fixed or in-substance fixed payments. These variable payments were *not* material in amount for the *three* and *six* months ended *June 30, 2025* and *2024*. 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 *15* — *Commitments and Contingencies*.

The Company's ground leases have remaining terms ranging between 16 to 73 years, including options for the Company to extend the terms. These leases expire between *2040* and *2097,* which include all lease extension options available to the Company. Certain of the Company's ground leases contain options to lease additional parcels of land at the Company's option within a specified period of time.

In *January 2025,* the Company executed a lease amendment with respect to its ground lease at APA to add an approximately *1* acre parcel of land to the existing lease (the "APA Lease Amendment").

***8.*** **Bonds payable, Loans payable, and Interest**

*Bonds payable*

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

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

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

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

As of *June 30, 2025* and *December 31, 2024*, the fair value of the Company's Series *2021*-*1* Bonds was approximately $138.8 million and $143.8 million, respectively. As of *June 30, 2025* and *December 31, 2024*, the fair value of the Company's bonds is estimated utilizing Level *2* inputs including prices for the bonds on inactive markets.

***9.*** **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* and *six* months ended *June 30, 2025*. During the *six* months ended *June 30, 2024,* 253,703 Warrants were exercised, resulting in approximately $2.9 million of proceeds. As of *June 30, 2025*, 15,798,155 Warrants remain outstanding.

The closing price of the Warrants was $1.70 and $2.92 per warrant on *June 30, 2025* and *December 31, 2024*, respectively. The aggregate fair value of the outstanding Warrants was approximately $26.8 million and $46.1 million as of *June 30, 2025* and *December 31, 2024*, respectively. During the *three* and *six* months ended *June 30, 2025*, the Company recorded unrealized gains associated with the change in fair value of the Warrants of approximately $21.8 million and $19.3 million, respectively. During the *three* and *six* months ended *June 30, 2024,* the Company recorded an unrealized gain of approximately $8.2 million and an unrealized loss of approximately $8.0 million, respectively, associated with the change in fair value of the Warrants.

***12.*** **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.

In addition to the lease payment commitments discussed in Note *7* — Leases, the ground leases to which the Company is a party contain covenants that require the Company to conduct construction of hangar facilities on the leased grounds within a certain period and in some cases, to spend a minimum dollar amount.

The DVT Lease requires approximately $14.6 million of improvements to be made for the DVT Phase II project within *12*-months after receiving permitting documents, but in *no* event later than *May 2027.*

The PWK Lease contains a requirement that the Company must commence construction within *six* months of the issuance of permits and must complete construction within *18* months of construction commencement. If the Company is unable to adhere to the prescribed timeline and unable to receive an extension from PWK, the PWK Lease is subject to termination.

The SJC Lease contains customary milestones by which the Company must complete additional construction.

The ORL Lease requires that the Company construct $30 million of improvements in its initial phase of construction within *24* months of the effective date of the lease. The ORL Lease contains other customary milestones by which the Company must commence and complete subsequent phases of construction.

The SLC Lease requires that the Company make minimum capital improvements of $40 million.

The TTN Lease requires that the Company make minimum capital improvements of $30 million.

The SWF Lease requires that the Company make minimum capital improvements of $60 million within *36* months of receiving certain environmental approvals associated with construction. In the event that the Company does *not* expend such amount within the prescribed timeline, such difference would become payable to SWF over a *24*-month period.

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

In addition to the matters described in this note, the Company is involved is various legal proceedings and claims in the ordinary course of its business. Although the Company cannot predict with certainty the ultimate resolution of these matters, which involve judgements that are inherently subjective, the Company does *not* expect that the ultimate disposition of such other contingencies or matters will materially affect its financial condition, results of operations or cash flows.

**Overview and Background**

We are an aviation infrastructure development company building the first nationwide network of home basing hangar campuses 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 home basing hangar 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 36 million square feet in the past fourteen 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 61% between 2010 and 2023. Moreover, over that same period, there was an 102% 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 $285 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, 2024 is over $52 billion, an increase of approximately 6% 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; 22

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

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 June 30, 2025.

<sup>(1)</sup> <br><sup>In June 2025, we updated our estimates of the estimated total construction cost, hangars, and rentable square footage of our properties in development to reflect updates in anticipated site plans, hangar specifications, and the impact of general macroeconomic conditions. 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.

**Recent Developments**

In April 2025, we entered into the HIO Lease at HIO with the Port of Portland. The HIO Lease covers approximately 13 acres of property at HIO. The initial term of the HIO Lease will be 35 years from the later of certificate of occupancy or 18 months from the expiration of the diligence period, as defined in the HIO Lease, with lease payments commencing contemporaneously with the term. The HIO Lease contains an option exercisable by the Company to extend the HIO Lease for an additional 10 years following the expiration of the initial term.

In April 2025, we entered into the SWF Lease at SWF with the Port Authority of New York and New Jersey. The SWF Lease covers approximately 16 acres of property at SWF. The initial term of the SWF Lease will be 30 years, with lease payments commencing on the earlier of hangar occupancy or 36 months from the receipt of certain environmental approvals. The SWF Lease contains three options exercisable by the Company to extend the SWF Lease for an additional total of 15 years following the expiration of the initial term.

**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 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. The level and volatility of fuel prices may also impact the general aviation industry and 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 home basing hangar campuses, we use various materials, assemblies, and labor components. We contract for our materials and labor with various 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. In February 2025, the President of the United States issued an executive order reimposing tariffs on steel imports from all sources, ending country and product exemptions, and broadening the application of the tariffs to fabricated steel products. This order became effective on March 12, 2025. There can be no assurance as to when or if these or other import tariffs, quotas or other duties may be enacted, enforced, extended, modified or terminated in the future, or the extent of the impact of such tariffs will have on the cost of our construction materials. We believe that it is possible that market conditions, including recent and proposed changes in trade policies, may lead to continued increases in construction costs and market rental rates for hangars within our development projects. 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.

In May 2023, we acquired a controlling interest in a metal building and hangar door manufacturer, that we expect will ultimately result in an increase in quality and a reduction in the overall cost of the metal building and hangar door components at future development projects. We expect that over time this vertical integration will enable us to deliver metal buildings to most of our development sites in shorter times as compared to the anticipated lead times associated with conventional metal building fabricators. We believe internal building fabrication will provide us opportunities to aggressively target continued schedule compression at most of our development projects in the future. In December 2023, we engaged several structural engineering firms to perform an independent peer review of the hangar buildings designed for our DVT Phase I and APA Phase I development projects. The independent peer reviews determined a significant design defect existed within our prototype hangar building designs that required retrofitting to both meet and exceed our standards and the respective local building codes. The anticipated retrofitting efforts were also applied to ADS Phase I, and we believe the aggregate additional cost of such retrofits totaled between $26 to $28 million. Such retrofitting efforts required an additional three to five months of construction duration for each project impacted. Given the design enhancements implemented at our APA Phase I, DVT Phase I, and ADS Phase I development projects, our total construction costs for these projects were each greater than our original estimates, and outside of the scope of the original guaranteed maximum price construction contracts. In March 2024, we funded the increase in estimated costs by contributing $27 million of our corporate cash holdings to SHC, thereby restricting the use of such cash to the project scope of the Series 2021 Bonds.

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 2024 and 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 aggressively 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 in September, November, and December 2024 and has indicated the potential for further rate cuts, 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 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***

We previously funded SHC with over $200 million to fund the two phases at our initial five ground leased airport locations. We maintain the ability to include up to $50 million in new projects outside the original five locations to be funded with a portion of the existing proceeds held by the trustee as long as certain approvals and supplemental consultant reports are provided showing that such new project would result in better coverage of debt service than previously contemplated projects. We exercised this ability utilizing approximately $26 million of the $50 million available and received the requisite approvals and reports in March 2023 with respect to our ADS Phase I development project.

We previously raised equity capital, along with potential future debt and further equity issuances, including the 2024 Purchase Agreement and 2023 Purchase Agreement (as defined herein) 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 additional airport campuses and reach up to 20 airport 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 per campus, with 65% to 75% 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 20 airport site business plan is estimated to cost approximately $1.2 billion, with approximately 65% to 75% 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, 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. |
| ***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 are the payments payable under our ground leases. For the six months ended June 30, 2025 and 2024, we recognized expense related to ground leases of approximately $6.5 million and $3.5 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 are 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 From (Used In) Operating Activities*** | We focus on measures designed to monitor cash flow, including net cash provided from (used in) operating activities. The presentation of net cash provided from (used in) operating activities provides a measure of performance which are 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, estimates and assumptions related to right-of-use assets and operating lease liabilities, and estimates and assumptions used in the determination of the fair value of assets acquired and liabilities assumed in the business combination. 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.

**Recent Accounting Pronouncements**

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

***Revenues***

Rental revenues for the three months ended June 30, 2025 were approximately $5.2 million, compared to approximately $3.2 million for the three months ended June 30, 2024. The $2.0 million, or 65%, increase was primarily the result of operations at CMA, which was acquired during the three months ended December 31, 2024 and the cumulative impact of increased occupancy at our BNA, OPF, and SJC hangar campuses.

Fuel revenues for the three months ended June 30, 2025 were approximately $1.3 million, compared to approximately $0.4 million for the three months ended June 30, 2024. The approximately $0.9 million, or 207%, increase was primarily the result of fuel sales at our CMA hangar campus, where our fuel revenues and related expenses are recognized on a gross basis.

***Operating Expenses***

Campus operating expenses increased approximately $1.2 million, or 122%, from approximately $1.0 million for the three months ended June 30, 2024, to approximately $2.2 million for the three months ended June 30, 2025. Salaries, wages, and benefits associated with our hangar campus personnel increased approximately $0.6 million, primarily driven by headcount increases in anticipation of the commencement of operations at our DVT, APA, and ADS hangar campuses and the acquisition of a hangar campus at CMA during December 2024. Other campus operating expenses increased approximately $0.6 million, primarily driven by increased insurance, property taxes, and utilities associated with operations at CMA and SJC, where our operations commenced in December 2024 and April 2024, respectively.

Fuel expenses for the three months ended June 30, 2025 were approximately $0.9 million, compared to approximately $0.1 million for the three months ended June 30, 2024. The approximately $0.8 million, or 1,026%, increase was primarily the result of our acquisition of CMA during the three months ended December 31, 2024, and the related impact of recognizing certain fuel revenue and expenses on a gross basis.

Ground lease expenses increased approximately $1.3 million, or 59%, from approximately $2.3 million for the three months ended June 30, 2024, to approximately $3.6 million for the three months ended June 30, 2025. The increase in ground lease expense was driven by the ground leases signed at SLC during the three months ended September 30, 2024, the ground leases assumed as part of the CMA Transaction during the three months ended December 31, 2024, and the ground leases signed at SWF and HIO during the three months ended June 30, 2025.

Depreciation and amortization increased approximately $0.8 million, or 130%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase was primarily driven by our acquisition of a hangar campus at CMA during the three months ended December 31, 2024 and the commencement of operations at our DVT campus during the three months ended June 30, 2025.

***Operating Expenses - Continued***

Pursuit and marketing expenses for the three months ended June 30, 2025 were approximately $0.6 million, compared to approximately $0.4 million for the three months ended June 30, 2024. The approximately $0.2 million, or 57%, increase was primarily the result of investment in our growth strategy in securing airport site acquisitions and potential tenants throughout the year.

Employee compensation and benefits expenses increased approximately $0.9 million, or 26%, to $4.3 million for the three months ended June 30, 2025, as compared to approximately $3.4 million for the three months ended June 30, 2024. The increase was primarily driven by an increase in corporate headcount and expense recognized associated with our equity compensation programs. Headcount and compensation expenses increased approximately $0.7 million, and non-cash equity compensation expense increased approximately $0.2 million.

For the three months ended June 30, 2025 and 2024, other general and administrative expenses were approximately $1.0 million and approximately $0.8 million, respectively. The approximately $0.2 million increase was primarily driven by slight 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 income increased from approximately $9.1 million of income for the three months ended June 30, 2024, to approximately $21.9 million of income for the three months ended June 30, 2025. This increase was primarily due to an approximately $13.6 million difference in the mark-to-market adjustment of the outstanding warrants at June 30, 2025 as compared to June 30, 2024 offset by an approximately $0.9 million decrease in other income driven by a reduction in interest income earned from investments in U.S. Treasuries.

***Operating Expenses***

Campus operating expenses increased approximately $2.3 million, or 130%, from approximately $1.8 million for the six months ended June 30, 2024, to approximately $4.1 million for the six months ended June 30, 2025. Salaries, wages, and benefits associated with our hangar campus personnel increased approximately $1.2 million, primarily driven by headcount increases in anticipation of the commencement of operations at our DVT, APA, and ADS hangar campuses, the acquisition of a hangar campus at CMA during December 2024, and the commencement of operations at our SJC hangar campus in April 2024. Other campus operating expenses increased approximately $1.1 million, primarily driven by increased insurance, property taxes, and utilities associated with operations at CMA where our operations commenced in December 2024, and start-up expenses associated with our DVT, APA, and ADS hangar campuses .

Fuel expenses for the six months ended June 30, 2025 were approximately $1.7 million, compared to approximately $0.2 million for the six months ended June 30, 2024. The approximately $1.5 million, or 969%, increase was primarily the result of our acquisition of CMA during the three months ended December 31, 2024, and the related impact of recognizing certain fuel revenue and expenses on a gross basis.

***Operating Expenses - Continued***

Pursuit and marketing expenses for the six months ended June 30, 2025 were approximately $1.1 million, compared to approximately $0.7 million for the six months ended June 30, 2024. The approximately $0.4 million, or 58%, increase was primarily the result of investment in our growth strategy in securing airport site acquisitions and potential tenants throughout the year.

Employee compensation and benefits expenses increased approximately $1.5 million, or 22%, to $8.5 million for the six months ended June 30, 2025, as compared to approximately $7.0 million for the six months ended June 30, 2024. The increase was primarily driven by an increase in corporate headcount and expense recognized associated with our equity compensation programs. Headcount and compensation expenses increased approximately $1.0 million, and non-cash equity compensation expense increased approximately $0.5 million.

For the six months ended June 30, 2025 and 2024, other general and administrative expenses were approximately $2.0 million and approximately $1.8 million, respectively. The approximately $0.2 million increase was primarily driven by slight 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 income increased from approximately $6.9 million of expense for the six months ended June 30, 2024, to approximately $19.6 million of income for the six months ended June 30, 2025. This increase was primarily due to an approximately $27.2 million difference in the mark-to-market adjustment of the outstanding warrants at June 30, 2025 as compared to June 30, 2024.

**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, (iii) other income, predominantly consisting of interest income and realized gains from sales of available-for-sale securities, (iv) non-cash equity-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.

Management uses Adjusted EBITDA to facilitate operating performance comparisons from period to period. We believe this non-GAAP financial measure provide investors, analysts and other interested parties useful information to evaluate our business performance as the removal of certain non-cash expenses and income, they facilitate 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 and other debt and the issuance of additional equity securities. We also have the ability to utilize our ATM Facility (as defined below) or otherwise utilize our shelf registration statement on Form S-3 to access the capital markets. However, as we have recently become a publicly-traded company, we cannot assure you that we will have access to these sources of capital or that, even if such sources of capital are available, that these sources of capital will be available on favorable terms. Our ability to incur additional debt will depend on multiple factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that are or may be imposed by future lenders. Our ability to access the equity and debt capital markets will depend on multiple factors as well, including general market conditions for real estate companies, our degree of leverage, the trading price of our common stock and debt and market perceptions about our Company.

Our cash deposits may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and the majority are maintained with a major financial institution with reputable credit. Our restricted cash is held in trust at a major financial institution pursuant to the Series 2021 Bonds indenture. We monitor the relative credit standing of financial institutions with whom we transact and limit the amount of credit exposure with any one entity. Our portfolio of investments and restricted investments is composed entirely of U.S. Treasury securities as of June 30, 2025.

The following table summarizes our cash and cash equivalents, restricted cash, investments, and restricted investments as of June 30, 2025 and December 31, 2024 (in thousands):

***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 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. During the three and six months ended June 30, 2025, we sold 20,472 shares of Class A Common Stock under the ATM Facility at a weighted-average sales price of $13.70. During the twelve months ended December 31, 2024, we sold 79,676 shares of Class A Common Stock under the ATM Facility at a weighted-average sales price of $13.75. As a result, we have approximately $98.6 million in remaining capacity under our ATM Facility.

We are not obligated to sell any shares under the ATM Agreement. The offering of shares pursuant to the ATM Agreement will terminate upon the earlier to occur of (i) the issuance and sale, through B. Riley, of all of the shares subject to the ATM Agreement and (ii) termination of the 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 of directors deems appropriate.

***Private Activity Bonds***

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

***Debt Covenants***

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

Covenants in the PABs require SHC to maintain a debt service coverage ratio (as defined in the relevant documents) of at least 1.25 for each applicable test period, commencing with the quarter ending December 31, 2024. The PABs are subject to a Continuing Disclosure Agreement whereby SHC is obligated to provide electronic copies of (i) monthly construction reports, (ii) quarterly reports containing quarterly financial information of SHC and (iii) annual reports containing audited consolidated financial statements of SHC to the Municipal Securities Rulemaking Board. As of June 30, 2025, we were in compliance with all debt covenants.

**Cash Flows**

The following table summarizes our sources and uses of cash for the six months ended June 30, 2025 and 2024 (in thousands):

---

| | | |
|:---|:---|:---|
|  | **Six months ended** | **Six months ended** |
|  | **June 30, 2025** | **June 30, 2024** |
| Cash and restricted cash at beginning of period | $94359 | $72266 |

| Net cash (used in) provided by financing activities | (1457) | 975 |
| Cash and restricted cash at end of period | $32105 | $122304 |

---

*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 $6.0 million for the six months ended June 30, 2025, as compared to cash used in operating activities of approximately $5.5 million for the same period in 2024. The $0.5 million increase in cash used in operating activities was primarily attributable to an approximately $2.1 million increase in net loss, net of non-cash adjustments and an approximately $1.6 million favorable change in working capital. The increase in net loss, net of non-cash adjustments was primarily driven by the impact of increases in headcount at both the corporate and hangar campus level, including start-up expenses incurred in anticipation of commencing operations at DVT, APA, and ADS. The favorable 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 $54.8 million for the six months ended June 30, 2025, as compared to cash provided by investing activities of approximately $54.5 million for the same period in 2024. The decrease of approximately $109.3 million of cash provided by investing activities was driven primarily by a decrease in proceeds received from held-to-maturity investments of approximately $69.1 million, an increase of capital expenditures of approximately $27.0 million, and an approximately $12.4 million increase in purchases of available for sale investments for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024.

*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 used in financing activities was approximately $1.5 million for the six months ended June 30, 2025, as compared to net cash provided by financing activities of approximately $1.0 million for the same period in 2024. The approximately $2.5 million increase in net cash used in financing activities was primarily driven by a decrease of $3.0 million in proceeds received from the exercise of Warrants during the six months ended June 30, 2024.
