**SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Report, including, without limitation, statements under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations," includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements can be identified by the use of forward-looking terminology, including the words "believes," "estimates," "anticipates," "expects," "intends," "plans," "may," "might," "will," "potential," "projects," "predicts," "continue," or "should," or, in each case, their negative or other variations or comparable terminology. There can be no assurance that actual results will not materially differ from expectations. These statements are based on management's current expectations, but actual results may differ materially due to various factors, including, but not limited to:

● expectations regarding the Company's strategies and future financial performance, including the Company's future business plans or objectives, prospective performance and commercial opportunities and competitors, services, pricing, marketing plans, operating expenses, market trends, revenues, liquidity, cash flows and uses of cash, capital expenditures, and the Company's ability to invest in growth initiatives;

● the effects of general economic conditions, including inflation, interest rates levels, and availability of construction materials for our development projects;

● the outcome of any legal proceedings that may be instituted against the Company or its predecessors in connection with the Business Combination and related transactions;

● our limited operating history makes it difficult to predict future revenues and operating results;

● financial projections may not prove to be reflective of actual financial results;

● the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, and the ability of the combined business to grow and manage growth profitably;

● changes in applicable laws or regulations;

● the possibility that the Company may be adversely affected by other economic, business, and/or competitive factors;

● our financial performance; and

● other risk factors included under "Risk Factors" in this Report.

The forward-looking statements contained in this Report are based on our current expectations and beliefs concerning future developments and their potential effects on us. Future developments affecting us may not be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) and other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described under the heading "Risk Factors." Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. These risks and others described under "Risk Factors" may not be exhaustive.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. We caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and developments in the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained in this Report. In addition, even if our results or operations, financial condition and liquidity, and developments in the industry in which we operate are consistent with the forward-looking statements contained in this Report, those results or developments may not be indicative of results or developments in subsequent periods.

**SUMMARY OF RISK FACTORS**

You should read this summary together with the more detailed description of each risk factor contained in Item 1A "Risk Factors" in this Report and the other reports and documents filed or furnished by us with the SEC for a more detailed discussion of the principal risks (as well as certain other risks) that you should carefully consider before deciding to invest in our securities. Some of the factors that could materially and adversely affect our financial condition and the market price of shares of our securities or our prospects include, but are not limited to, the following.

*Risks Relating to Our Business*

• We have a limited operating history and could experience significant operating losses in the future.

• Our business, and the aviation industry generally, are subject to downturns in the economy and disruption and volatility in the financial markets.

• Our growth will depend in part upon our ability to enter into new ground leases at airports, and we may be unsuccessful in identifying and consummating attractive new ground leases or taking advantage of other investment opportunities, which would impede our growth and materially and adversely affect our business and results of operation.

• Our ability to meet our obligations under our ground leases and our indebtedness is dependent on our ability to enter into and collect lease payments from tenants.

• We have a substantial amount of indebtedness outstanding, which may expose us to the risk of default under our debt obligations, restrict our operations and our ability to grow our business and revenues.

• Secured debt obligations, including those under the "Series 2021 PABs" (as defined herein), expose us to the possibility of foreclosure, which could result in the loss of our investment in a property or group of properties subject to mortgage debt.

• Our growth will depend on our access to external sources of capital, and our ability to obtain financing or access capital markets may be limited.

• Increases in market interest rates or unavailability of additional indebtedness may make it difficult for us to finance or refinance our debt, which could have a material adverse effect on our financial condition, results of operations and growth prospects.

• An epidemic, pandemic, or contagious disease, including the ongoing COVID-19 pandemic, could have a material adverse effect on our business and results of operations.

• We may be required to record impairment charges to future earnings if our long-lived assets become impaired.

• The industry in which we operate is subject to significant competition and our failure to effectively compete could have a material adverse effect on our business and results of operations.

• The growth and success of our business is subject to our ability to market and to attract and retain tenants.

• Our rental income is initially concentrated within a small number of tenants and the loss of or default by one or more significant tenants could have a material adverse effect on our business and results of operations.

• Our capital projects are subject to uncertainties, including the possibility of delays, cost overruns, and inflation, which could have a material adverse effect on our business, results of operations and market reputation.

• Failure to adequately maintain our HBS hangar campuses or the integrity of our fuel supplies may have a material adverse impact on the revenue or market share of one or more of our HBS hangar campuses resulting in a decline in operations of the business.

• The growth and success of our business is dependent on the continued service of certain key employees and the ability to recruit and retain new employees.

• Our management team has no prior experience operating a public company, and we cannot assure you that the past experience of our senior management team will be sufficient to successfully operate as a public company.

• If we fail to maintain effective internal control over financial reporting, we may not be able to accurately report our financial results, which may adversely affect investor confidence in the Company and, as a result, the value of our common stock.

• We conduct substantially all of our operations under ground leases, which grant significant rights to airport authorities as our direct or ultimate landlord.

------

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

*Risks Relating to Tax*

• Our only principal asset is our interest in Sky, and accordingly we are dependent on distributions from Sky to pay dividends, taxes, other expenses, and make any payments required to be made under the Tax Receivable Agreement.

• In certain cases, payments under the Tax Receivable Agreement may (i) exceed any actual tax benefits the Tax Group realizes or (ii) be accelerated.

*Risks Relating to Our Common Stock and Warrants*

• The market price of Class A Common Stock and Public Warrants has been and may continue to be extremely volatile, which could cause purchasers of our securities to incur substantial losses.

• The public float of our Class A Common Stock is very illiquid, and there may not be sufficient demand in the marketplace to absorb the sale of newly registered shares.

• We cannot predict the impact our dual class structure may have on the stock price of Class A Common Stock.

• The outstanding Warrants are exercisable for shares of Class A Common Stock and common units in Sky may be redeemed for Class A Common Stock upon expiration of the applicable lock-up period. The exercise of these outstanding Warrants will increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

• You may experience future dilution as a result of future equity offerings.

**Business Combination**

On January 25, 2022 (the "Closing Date"), we completed the Business Combination pursuant to the Equity Purchase Agreement between us and Sky. Each of the Existing Sky Equityholders separately entered into an Equityholders Voting and Support Agreement irrevocably agreeing to vote in favor of the Business Combination set forth in the Equity Purchase Agreement. As contemplated by the Equity Purchase Agreement, the following occurred on the Closing Date: (a) YAC changed its name to "Sky Harbour Group Corporation"; (b) all outstanding shares of Sponsor Stock held by the Sponsor were converted into shares of Class A Common Stock of the Company; (c) Sky restructured its capitalization, issued to the Company 14,937,581 Sky Common Units, which was equal to the number of outstanding shares of Class A Common Stock immediately after giving effect to the Business Combination (taking into account the redemption of Class A Common Stock and the Class A Common Stock issued under the BOC PIPE investment (the "BOC PIPE")), reclassified the existing Sky Common Units (other than the Sky Incentive Units), existing Sky Series A Preferred Units and the existing Sky Series B Preferred Units into Sky Common Units; (d) certain adjustments to the number of Sky Incentive Units were effected to reflect the new capital structure; (e) the Company was appointed as the managing member of Sky; (f) the Sky Common Units issued to BOC YAC in respect of its Series B Preferred Units were converted into 5,500,000 shares of Class A Common Stock; (g) holders of Sky Common Units received one share of Class B Common Stock for each Sky Common Unit, and as consideration for the issuance of 14,937,581 Sky Common Units by Sky to the Company, YAC contributed to Sky the net amount held in the YAC trust account after redemptions and taking into account the BOC PIPE and the amount of various transaction costs; and (h) each YAC Warrant that was issued and outstanding immediately prior to the closing became a Warrant (the transactions referred to in clauses (a) through (h), collectively, the "Business Combination").

As a result of the Business Combination, the Company is organized as an "Up-C" structure in which substantially all of the operating assets of Sky's business are held by Sky. The Company's only assets are its equity interests in Sky.

As of January 26, 2022, the Class A Common Stock and Warrants of the Company began trading on the New York Stock Exchange American LLC (the "NYSE American") as "SKYH" and "SKYH WS," respectively. The disclosure in this section gives effect to the Business Combination and includes the operations of Sky prior to the Business Combination.

**Overview**

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

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

These larger footprint aircraft do not fit in much of the existing hangar infrastructure and impose stacking challenges and constraints in the traditional shared or community hangars operated by 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.

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

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

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

In contrast with community hangars and other facilities provided by FBOs, the HBS hangar campuses we develop provide the following features and services:

• private hangar space for exclusive use of the tenant;

• adjoining configurable lounge and office suites;

• line crews and services dedicated exclusively to tenants;

• climate control to mitigate condensation and associated corrosion;

• features to support in-hangar aircraft maintenance;

• no-foam fire suppression; and

• customized software to provide security, control access and monitor hangar space.

We use a standard set of proprietary prototype hangar designs, which are intended to deliver high-quality business aviation facilities, lower construction costs, minimize development risk, expedite permit issuance, and facilitate the implementation of refinements across its portfolio. Hangar features include:

• the ability to accommodate heavy business jets in single configuration, medium jets in twin or triplet configuration, or light jets in multi-configuration;

• compliance with National Fire Protection Association ("NFPA") 409 Group III fire code, eliminating foam fire protection systems, resulting in lower construction costs and operating expenses, as well as eliminating accidental foam discharges and the resultant negative effects on aircraft maintenance and resale value;

• high-voltage capability, industrial drainage and impervious floors that support in-hangar maintenance and inspections; and

• control through smartphone application.

Our product strategy aims to attract tenants with exclusive access to their aircraft, minimize the risk of damage to aircraft, provide increased access, security and control, facilitate maintenance, and improve pre-flight and post-flight convenience. We believe that with no transient traffic, our HBS hangar campuses offer a shorter time to wheels-up, even during periods of peak traffic.

We believe demand for HBS services will be driven broadly by the growing size of the business aviation fleet in the United States and the delivery of larger aircraft with taller tail heights. The discovery by first-time flyers in the convenience, control and comfort of general aviation has caused a shift in consumer behavior which we believe will also support increasing demand for HBS services.

While private aircraft use generally was not affected to the extent of commercial aviation, and some private aircraft clients may continue to use that mode of aviation following the pandemic, preferences for air travel and specifically general aviation are unknown and may change following COVID-19. See "*Risk Factors* — *An epidemic, pandemic or contagious disease, including the ongoing COVID-19 pandemic, could have a material adverse effect on our business and results of operations."*

**Tax Exempt Senior Bond Issuance**

On September 14, 2021, Sky's subsidiary, Sky Harbour Capital LLC ("SHC"), closed a $166.3 million financing through the sale of Series 2021 private activity tax-exempt senior bonds through a municipal conduit issuer, Public Finance Authority (Wisconsin) (the "Series 2021 PABs"). See "*Management*'*s Discussion & Analysis of Financial Condition and Results of Operations*—*Liquidity and Capital Resources* — *Private Activity Bonds*" for more information regarding the Series 2021 PABS. The use of proceeds from this issuance, together with proceeds from the sale of the $55.0 million of Sky Series B Preferred Units to BOC YAC, were used, in part, to fund a construction escrow account for Sky's development program at five airports consisting of existing and new hangars in various phases of development and construction and to repay all existing indebtedness of Sky.

Each constructed facility is expected to consist of clusters of between 9 and 19 hangars. On average, each hangar provides 12,000 square feet of hangar space and 1,300 to 2,000 square feet of office space. Once completed, these facilities are expected to total 80 hangars on 87 acres of ground leases, with an infrastructure of over 1,095,000 square feet expected to be completed in the next five years.

We intend to lease each respective hangar to one or more tenants, who will use all or a portion of such facility for general aviation aircraft storage and related uses permitted under the respective ground leases and will pay rent and other charges derived from HBS services on the respective sites to us pursuant to a sublease.

***Sugar Land Site***

***The Airport.*** SGR is located approximately 20 miles southwest of the Houston central business district. The airport is situated on 622 acres owned by the City of Sugar Land. SGR is a publicly-owned, public-use general aviation facility, and it is included in the Federal Aviation Administration's ("FAA") National Plan of Integrated Airport Systems ("NPAIS").

SGR is designated as a "reliever airport" for George Bush Intercontinental Airport and William P. Hobby International Airport in Houston, Texas. 24 companies on the 2022 Fortune 500 list are headquartered in the Houston metro area. General airport facilities at SGR include an 8,000-foot primary runway, as well as fuel services, aircraft storage in hangars, and tie-down parking. SGR includes United States Customs facilities. SGR is home to seven on-airport businesses that offer services such as FBO amenities, aircraft maintenance, and avionics. The most frequent general aviation operations at SGR involve business and charter flights, flight instruction, recreational flying and law enforcement.

Between 2018 and 2019, SGR experienced a 12.0% increase in overall operations based on data from FAA OPSNET. The effects of the COVID-19 pandemic can be seen in the change from 2019 to 2020: total operations at SGR decreased 12.3%. The 11.6% increase in operations from 2020 to 2021 is largely attributable to a return to pre-pandemic levels of operations. According to forecast data from FAA TAF, the general aviation recovery is projected to continue through 2023 and 2024, with growth projections of 6.5% and 6.9%, respectively.

The sole FBO onsite at SGR is the primary competition for our HBS hangar campus at SGR. Another company located at SGR has maintenance hangars onsite, and can accommodate short-term hangar rentals without FBO services.

***Opa-Locka Site***

***The Airport.*** OPF is located approximately 10 miles north of the Miami central business district, 16 miles from Miami Beach and seven miles from Miami International Airport ("MIA"). OPF, a public-use general aviation facility owned by Miami-Dade County and operated by the Miami-Dade Aviation Department.

The Miami Airport System consists of five active airports, with OPF being the largest general aviation airport in the system and designated as a reliever to MIA. Notably, OPF ranks eighth in the FAA's Top Ten Airports for Domestic Business Jet Operations, with 55,223 domestic business jet operations during the period February 2022 through January 2023. Facilities at OPF include three runways which are all served by full-length paved parallel taxiways. Other facilities at OPF include hangars and tie-downs for aircraft parking and fuel services.

Data from FAA OPSNET indicates that between 2018 and 2019, OPF experienced a 10.3% increase in overall operations. The effects of the COVID-19 pandemic were apparent in the change from 2019 to 2020 as total operations at OPF decreased 20.8%. The 21.2% increase in operations from 2020 to 2021 is largely attributable to a partial return to pre-pandemic levels of operations. Forecast data from FAA TAF projects increases of 4.8%, 3.8%, and 4.1% for 2022, 2023, and 2024, respectively.

The existing stock of hangar space at OPF comprises approximately 266,000 square feet of space, with an additional 350,000 square feet of new construction hangar space planned. There are six large, nested T-Hangar rows on the airport, capable of storing 99 aircraft.

***Nashville Site***

***The Airport.*** BNA is the primary commercial air service facility serving the Nashville metropolitan area and is the largest airport in the State of Tennessee. As the only medium hub in the region, BNA serves as the primary commercial service airport for the air service area. BNA is one of the nation's fastest-growing airports. The combination of Nashville's robust economy and business and tourism appeal led to seven successive years of often double-digit growth, which ended with 18.5 million passengers that passed through the airport in 2022.

BNA has four runways, the longest of which is 11,030 feet. Berry Field Air National Guard Base is located on the premises of BNA and it has hosted the 118<sup>th</sup> Airlift Wing since 1937.

According to FAA OPSNET, between 2018 and 2019 BNA experienced a 7.5% increase in overall operations. The effects of the COVID-19 pandemic can be seen in the change from 2019 to 2020 as total operations at BNA decreased 30.5%. From 2020 to 2021, a significant increase of 34.3% was recorded, and was largely attributable to a rebound to operation levels experienced prior to the pandemic. FAA TAF forecast data projects a slight decline of 3.6% in 2022 due to lower projected commercial operations, followed by projected increases of 14.0%, 5.1%, and 4.6% in 2023, 2024, and 2025, respectively.

There are two FBOs at BNA offering the following amenities: pilot's lounge, waiting area/lounge, weather station, restroom, showers, kitchenette, and conference rooms, flight instruction, rental car, aircraft maintenance and parts supply, hangar rental, aircraft tie-down parking, and aircraft fueling. In addition, there are several private hangars at BNA which generally provide storage for business aircraft, office space, maintenance space, and passenger/pilot lounges. Some of the private hangars are owned and built by individuals, while others are leased from one of the FBOs. Aside from our BNA HBS hangar campus, no private hangar space for larger aircraft is currently available at BNA.

***Deer Valley Site***

***The Airport.*** DVT is a medium sized, predominantly business and general aviation airport that is owned and operated by the City of Phoenix. DVT is located on 914 acres within Phoenix's northern limits, approximately 20 miles north of downtown and approximately 17 miles north of Phoenix Sky Harbor International Airport ("PHX"). DVT serves to relieve general aviation air traffic from PHX and is a convenient alternative to the larger and more congested airport. This convenience has led DVT to become one of the busiest general aviation airports in the country, ranking second in the FAA's Top 10 Busiest General Aviation Airports, as of 2017. The airport is also home to several flight schools. No commercial passenger service operations are available; however, air taxi service is available.

DVT has two parallel runways. The airport offers a complete range of services including fueling, avionics repair, maintenance, parts, flight training, new and used aircraft sales, aircraft rentals, a pilot shop, and a restaurant. The landside facilities at DVT include the terminal building, an FBO, flight schools, fueling facilities, major utilities, and support facilities.

Based on data from FAA OPSNET, between 2018 and 2019, DVT experienced a 10.0% increase in overall operations. The effects of the COVID-19 pandemic can be seen in the change from 2019 to 2020 as total operations at DVT decreased 12.0%, and the effects of the pandemic continued to be evident in the change from 2020 to 2021, as total operations at DVT decreased a further 32.4%. FAA TAF forward looking data forecasts a rebound in total operations beginning in 2022 and increasing each year thereafter, including increases of 18.9%, 18.1% for 2022 and 2023, respectively.

Currently, the only aircraft hangar rental providers at DVT are the DVT Airport Authority and an FBO. According to the DVT Airport Authority, they do not have any corporate/executive hangars, but they have available land to build hangars. The FBO is currently based in two locations at DVT and its future plans at DVT include the construction of new hangars as well as a modern FBO facility.

***Addison Airport Site***

***The Airport.*** ADS is owned and operated by the Town of Addison. The airport serves the Dallas/Fort Worth Metroplex market and is in close proximity to the residential and business districts where aircraft owners and operators live and work, located only nine miles north of the central business district of Dallas. ADS does not cater to commercial flights, making it preferable for basing business aircraft as it provides for the quickest "time-to-wheels-up" in the Dallas area. According to its website, ADS is home to more than 650 based aircraft.

Facilities at ADS include a 7,203 foot runway equipped with high-intensity lighting and a full length parallel taxiway. Operations are supported by Instrument Landing System (ILS) and RNAV (GPS) instrument approaches. The airport offers an FAA control tower, 24-hour U.S. Customs services for international arrivals, no landing fees, and over 70 businesses including maintenance providers, flight schools, and various other aviation-related service providers. According to the Texas Department of Transportation, as of 2018 the airport contributes over 1,000 on-airport jobs to the Town of Addison.

Between 2018 and 2019, ADS experienced a 6.1% increase in overall operations. The effects of the COVID-19 pandemic can be seen in the change from 2019 to 2020 as total operations at ADS decreased 15.9%. Operations at ADS rebounded from 2020 to 2021, as the airport experienced a 22.8% increase in total operations. FAA TAF forward looking data forecasts a continued rebound in total operations beginning in 2022 and increasing each year thereafter, including increases of 1.1%. 4.8%, and 3.7% for 2022, 2023, and 2024, respectively.

Aircraft hangar rental providers currently on the airport consist of three FBOs. Additionally, multiple smaller private hangars exist on the airport, primarily owned by operators or for flight schools and other airport businesses.

The existing hangar facilities at ADS are overcapacity and predominantly older with low door heights, which creates little opportunity for attracting newer larger private jet aircraft to the market. Though a new FBO brought additional community hangar square footage to the airport, the combination of older current facilities, lack of private hangar space on the airport, increased wealth migration to the north side of Dallas, and substantial popularity of the airport make for an attractive target for our private and exclusive Home-Basing solution.

***Addison Site Facilities.*** We obtained lease rights to approximately six acres on the northeast side of the primary runway. As part of our development plan, the existing facilities on the site, including a terminal, ramp and automobile parking, will be demolished. We anticipate subsequently developing six hangars with adjoining office and support space constituting approximately 105,000 square feet. Anticipated occupancy for the ADS site is in the third calendar quarter of 2024. In January 2023, we amended our existing ground lease agreement with the Town of Addison, TX to include additional parcels of land that will effectively double the land available for development at our ADS HBS hangar campus project.

**Customers, Sales and Marketing**

We seek to maximize hangar rental charges consistent with capacity utilization at our existing and future facilities. Rental hangar space is open to the public on a non-discriminatory basis, and prospective tenants are reviewed for credit quality and nature of intended use of the facilities. We focus our operations on various types of tenants, including, individuals (directly or through personally or family-owned LLCs), charter operations, flight schools, corporate fleets, government entities and aviation service providers. We intend to develop a diversified portfolio of tenants in terms of geography, type of tenant and length of lease term.

While much of our historical revenue has been concentrated with our two largest tenants, longer term, we do not expect to depend on a single tenant or group of tenants, the loss of which would have a material adverse effect on our business. We expect to diversify our risk by having multiple types of tenants across multiple locations across the country. See "*Risk Factors* — *Our rental income is initially concentrated within a small number of tenants and the loss of or default by one or more significant tenants could have a material adverse effect on our business and results of operations.*"

Tenant lease terms are generally 1-10 years, with maturity dates staggered for purposes of risk management. Base lease rents vary by location, but all leases feature annual rent escalation. Leases are structured as either gross or triple-net, with tenants covering insurance, taxes and utilities. The tenant leases do not have early termination options, and renewals are generally reset to fair market value.

**Competition**

The hangar space rental segment of the aviation services industry in which we operate is very competitive. We compete with national, regional and local FBOs and other hangar real estate companies. Our competitors may include FBOs currently operating at certain airports that may have financial or other resources and/or lower cost structure than us. Other competitors have been in business longer than us and may have greater financial resources available.

We compete with other operators, including FBOs, at all of our current locations, and our hangar campuses may also face indirect competition from operators located at nearby airports. In addition, we may be adversely affected by competition from other facilities within or outside the airports where the facilities are located, including construction of new facilities at the airports at which we operate or the expansion of hangar facilities by competitors at nearby airports. We must compete with other operators based on the location of the facility relative to runways and street access, quality of customer service, safety, reliability, value-added features, and price. See "— *Investment Criteria*" for additional information regarding our competitors with respect to each particular facility.

**Seasonality**

We do not experience substantial seasonal fluctuations in our revenues and the results of operations.

**Government Regulation**

*FAA Regulation*

The industry is overseen primarily by the FAA. In addition, the Department of Homeland Security, Department of Transportation, Environmental Protection Agency, state and local environmental agencies, and local airport authorities contribute to the regulation of our HBS hangar campuses. We must comply with federal, state, and local environmental statutes, and regulations, including those associated in part with the operation of fuel storage tank systems and fuel trucks. These requirements include, among others, tank and pipe testing for tightness, soil sampling for evidence of leaking, and remediation of detected leaks and spills.

*Environmental and Related Matters*

Our HBS hangar campuses are subject to regular inspection by local environmental agencies, as well as local fire marshals and other agencies. We do not expect that compliance and related remediation work, if any, will have a material negative impact on our business. We have not received notice requiring us to cease operations at any location or of any abatement proceeding by any government agency for failure to comply with applicable environmental laws and regulations.

*Americans with Disabilities Act*

Under Title III of the Americans with Disabilities Act ("ADA"), and rules promulgated thereunder, in order to protect individuals with disabilities, public accommodations must remove architectural and communication barriers that are structural in nature from existing places of public accommodation to the extent "readily achievable." In addition, under the ADA, alterations to a place of public accommodation or a commercial facility are to be made so that, to the maximum extent feasible, such altered portions are readily accessible to and usable by disabled individuals. The "readily achievable" standard takes into account, among other factors, the financial resources of the affected site and the owner, lessor or other applicable person.

Compliance with the ADA, as well as other federal, state and local laws, may require modifications to properties we currently own or may purchase, or may restrict renovations of those properties. Failure to comply with these laws or regulations could result in the imposition of fines or an award of damages to private litigants, as well as the incurrence of the costs of making modifications to attain compliance, and future legislation could impose additional obligations or restrictions on our properties. Although our tenants are generally responsible for all maintenance and repairs of the property pursuant to our leases, including compliance with the ADA and other similar laws or regulations, we could be held liable as the owner of the property for a failure of one of our tenants to comply with these laws or regulations.

**Environmental Matters**

Our business is subject to numerous statutes, rules and regulations relating to environmental protection and is exposed to various environmental risks, hazards, and environmental protection requirements, including those related to the storage and handling of jet fuel and compliance with firefighting regulations. See "*Risk Factors* — *Our businesses are subject to environmental risks that may impact our future profitability*" of this Report.

We endeavor to be a leader of the industry's initiatives to address environmental issues, and we are increasingly focused on how we can reduce our carbon footprint in a sustainable way. As part of this, our HBS hangar campuses are designed to reduce the need to reposition private jets, which reduces the use of fuel as well as air emissions and noise pollution. We operate a fleet of electric ground support equipment which have a low cost to operate and maintain. In addition, our HBS hangar campuses are designed to be electric vehicle charger-equipped and electric airplane charger-ready. In addition, our hangar design contains environmentally friendly aspects such as no-foam fire suppression. Moreover, our hangars are designed to be both solar and wind energy capable for future installation.

**Insurance**

We maintain insurance of the types and in amounts that we believe to be adequate and consistent with industry standards. During construction, our principal coverage includes builder's risk, general liability, excess liability, and contractor's pollution liability insurance. Once operational, each campus maintains commercial property, flood, earthquake, boiler and machinery, business income/loss of rent, automobile liability, general liability, environmental liability, and worker's compensation insurance. We also maintain insurance coverage related to our directors and officers, employment-related liabilities, and cyber-related incidents. We require the tenants at our campuses to maintain aircraft physical damage, general liability, worker's compensation, automobile liability, and pollution liability insurance coverage.

**Human Capital**

As of December 31, 2022, we had 23 employees and 11 independent contractors, none of which were subject to collective bargaining agreements. We also engage consultants to supplement our permanent workforce. Our operations are overseen by senior personnel with experience in business aviation and real estate, and includes top-level design, construction, operations, and finance expertise. We consider our employee relations to be in good standing. We are committed to keeping our employees informed and supported through regular communication and events, including our monthly town hall meetings.

We strive to recruit from amongst the best talent in the industry and reward them appropriately. Our success depends in large part on our ability to attract, retain and develop high-quality management, operations, and other personnel who are in high demand, are often subject to competing employment offers, and are attractive recruiting targets for our competitors in fields such as aviation and real estate.

We believe we offer competitive compensation (including base salary, incentive bonus, and long-term equity awards) and benefits packages designed to attract and reward talented individuals who possess the skills necessary to support our business objectives and assist in the achievement of our strategic goals and development plans. All employees are eligible for health insurance, a retirement plan, and life/disability coverage.

Human capital strategies are developed and managed by our Chief Operating Officer, who reports to the Chief Executive Officer, and are overseen by the compensation committee and the Board. Our executive management team regularly review and update our talent strategy, monitoring a variety of data, including turnover, diversity, and tenure, to design and implement effective recognition, training, development, succession, and benefit programs to meet the needs of our business and our employees.

**Legal Proceedings**

We may be involved from time to time in ordinary litigation, negotiation, and settlement matters that will not have a material effect on our operations or finances. We are not currently party to any material legal proceedings, and we are not aware of any pending or threatened litigation against us that we believe could have a material adverse effect on our business, operating results, or financial condition.

**Periodic Reporting and Financial Information**

Our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and all amendments to those reports, filed with or furnished to the Securities and Exchange Commission (the "SEC"), are available free of charge through the investor relations sections of the Company's website, www.skyharbour.group, as soon as reasonably practicable after we have electronically filed such material with, or furnished it to, the SEC. In addition, the SEC maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC at www.sec.gov.

| **ITEM 1A.** | **RISK FACTORS** |

---

*Certain factors may have a material adverse effect on our business, financial condition and results of operations. You should consider carefully the risks and uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including our financial statements and related notes. If any of the following events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results.*

**Risks Relating to Our Business**

***Our growth depends in part upon our ability to enter into new ground leases at airports, and we may be unsuccessful in identifying and consummating attractive new ground leases or taking advantage of other investment opportunities, which would impede our growth and materially and adversely affect our business and results of operation.***

Our ability to expand through new ground leases at airports is integral to our long-term business strategy and requires that we identify and consummate suitable new ground leases or investment opportunities in real estate properties for our portfolio that meet our investment criteria and are compatible with our growth strategy. Our ability to enter into new ground leases on favorable terms, or at all, may be adversely affected by the following significant factors:

● we may not be able to negotiate new ground leases with airport authorities on attractive terms or at all;

● we may encounter competition from other potential ground lessors, which could significantly increase the lease rate for properties we seek to lease;

● we may incur significant costs and divert management attention in connection with evaluating and negotiating potential new ground leases, including ones that we are subsequently unable to complete;

● 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; and

● we may be unable to obtain financing for the development of additional sites on favorable terms, or at all, as a result of our existing indebtedness, market conditions or other factors

***Our ability to meet our obligations under our ground leases and our indebtedness is dependent on our ability to enter into and collect lease payments from tenants.***

Our ability to meet our obligations under the ground leases and our debt service obligations will depend on our ability to generate revenues sufficient in the aggregate to make our payments under the ground leases and our debt service obligations under our outstanding indebtedness and any other indebtedness incurred in the future. Our ability to generate revenues may be adversely affected by a wide variety of unforeseen or unforeseeable events and conditions, including, without limitation, economic changes affecting the HBS industry generally, the airports or the tenants specifically, any of which could result in a default under the tenant leases. In addition, the ability of tenant leases to generate revenues may be adversely affected by competition from other facilities within or outside the airports where the facilities are located, including construction of new facilities at the airports at which we operate or the expansion of hangar facilities by competitors at nearby airports. There can be no assurances that the airports or their competitors will not undertake future improvements that may adversely impact the ability of tenant leases to generate revenues.

Moreover, the terms of our tenant leases currently in place do not extend past the final maturity date of our bond debt. Our ability to make payments under the ground leases or under our debt service obligations through their final maturity will depend upon our success in renewing current tenants or in re-leasing these facilities. The loss of one or more of tenants may (without a similar tenant or tenants to replace such tenant or tenants) have a material adverse effect on our ability to collect rental revenue sufficient to meet our obligations.

***We have a substantial amount of indebtedness outstanding, which may expose us to the risk of default under our debt obligations, restrict our operations and our ability to grow our business and revenues.***

Our outstanding indebtedness is secured under the terms of the Series 2021 PABs. We intend to incur additional debt in connection with new hangar projects at new airport locations, refinancing of existing indebtedness, future acquisitions, or for other purposes.

In addition, the Series PABs include, and we expect any other indebtedness we incur in the future to include, customary events of default, the occurrence of any of which, after any applicable cure period, would permit the holders of such indebtedness, among other things, to accelerate payment of all amounts outstanding under such indebtedness and to exercise their remedies with respect to the collateral, including foreclosure and sale of the real estate interests securing the loans. If any one of these events were to occur, our business and results of operations could be materially and adversely affected.

------

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

***Secured debt obligations, including those under the Series 2021 PABs, expose us to the possibility of defaults and cross-defaults, as well as foreclosure, which could result in the loss of our investment in a property or group of properties subject to mortgage debt.***

Each constructed and in-construction facility in our portfolio is subject to secured indebtedness under the Series 2021 PABs. Secured debt obligations increase the risk of property losses because defaults on indebtedness secured by properties may result in foreclosure actions initiated by holders of the Series 2021 PABs, its trustee, or other lenders and ultimately our loss of the property securing any loans for which it is in default. As described above, our current tenant leases do not extend past the maturity date of the Series 2021 PABs, and as a result we will be required to re-lease hangars as vacancies arise in order to continue to generate revenue to meet our debt service obligations under the Series 2021 PABs. If any of our facilities are foreclosed upon due to a default, it could materially and adversely affect our business and results of operations.

In addition, the agreements that govern our current indebtedness contain, and the agreements that may govern any future indebtedness that we may incur may contain, financial and other restrictive covenants, which may limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default that, if not cured or waived, could result in the acceleration of our debt and loss of any collateral securing such debt.

***Our growth will depend on our access to external sources of capital, and our ability to obtain financing or access capital markets may be limited.***

Our growth will depend on external sources of capital in order to finance the development of new properties. We may not be able to obtain such financing on favorable terms, in the time period we desire, or at all. There are a number of factors that may limit our ability to raise financing or access capital markets in the future, including future debt and future contractual obligations, our liquidity and credit status, our operating cash flows, the trading price of our Class A Common Stock, the market conditions in the aviation and/or real estate industries, U.S. and global economic conditions, and the general state of the capital markets. We cannot assure you that we will be able to source external financing for our capital needs, and if we are unable to source financing on acceptable terms or at all, our business could be materially adversely affected. If we cannot obtain capital from third-party sources, we may not be able to grow our business when strategic opportunities exist, meet the capital and operating needs of our existing properties or satisfy our debt service obligations. To the extent we finance our activities with additional debt, we may become subject to financial and other covenants that may restrict our ability to pursue our business strategy or otherwise constrain our growth and operations.

***Increases in market interest rates or unavailability of additional indebtedness may make it difficult for us to finance or refinance our debt, which could have a material adverse effect on our financial condition, results of operations and growth prospects.***

We expect to issue additional debt to finance future site developments and higher interest rates would impact our overall economic performance. In addition, we are subject to credit spreads demanded by fixed income investors. As a non-rated issuer, increases in general of credit spreads in the market, or for us, may result in a higher cost of borrowing in the future. If additional indebtedness is unavailable to us at reasonable rates or at all, we may not be able to finance additional projects or refinance existing debt when it becomes due. If interest rates are higher when we refinance our debt, our income and cash flow could be reduced as a result of increased debt service requirements, which may hinder our ability to raise more capital by issuing more stock or by borrowing money. Our ability to successfully issue any additional debt will depend on a range of factors, including general economic conditions, the level of activity in capital markets generally, and the terms of our existing indebtedness then in effect.

***Adverse economic and geopolitical conditions and dislocations in the credit markets could have a material adverse effect on our financial condition, results of operations, cash flow, and ability to service our debt and ground lease obligations.***

Our business has been, and may in the future be, affected by market and economic challenges experienced by the U.S. economy or the real estate industry as a whole, increased inflation and rising interest rates. Such conditions may materially and adversely affect us as a result of the following potential consequences, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a decreased demand for private airport hangar space, which would cause our rental rates to be negatively impacted

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to obtain financing on terms and conditions that we find acceptable, or at all, may be limited, which could reduce our ability to pursue new ground leases and development sites; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• declines in the financial condition of our tenants could make it more difficult to collect rental revenue from them.

If the U.S. economy experiences an economic downturn, we may experience delays in leasing vacant sites, which could negatively impact our financial condition, results of operations, cash flow, and ability to service our debt obligations. Furthermore, our ability to grow and lease new sites will be inhibited.

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

***An epidemic, pandemic or contagious disease, including the ongoing COVID-19 pandemic, could have a material adverse effect on our business and results of operations.***

We face risks related to an epidemic, pandemic or contagious disease, including the ongoing COVID-19 pandemic, which have impacted, and in the future could impact, the markets in which we operate and could materially and negatively impact our business and results of operations. The impact of such events and measures to prevent the spread of such an event could materially and adversely affect our business in a number of ways. For example, reductions in passenger volumes and flights, as well as by the broader economic shutdown resulting from an epidemic, pandemic or contagious disease could materially and negatively impact our business and results of operations.

Furthermore as the COVID-19 pandemic continues to subside, the demand for private air travel that increased during the pandemic may decrease, which may result in decreased demand for private airport hangar space and could materially and negatively impact our business and results of operations.

***We may be required to record impairment charges to future earnings if our long-lived assets become impaired.***

Accounting principles generally accepted in the United States of America ("GAAP") require us to assess our long-lived assets for impairment at least annually. In addition, we assess our long-lived assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Depending on the results of our review, we could be required to record a significant charge to earnings in our consolidated financial statements during the period in which any impairment of our long-lived assets were determined, negatively impacting our results of operations. In June 2022, the Company evaluated the development progress related to its smart hangar app. In connection with this evaluation, the Company recognized an impairment loss of approximately $0.2 million during the year ended December 31, 2022. See "Note 5 — Long-lived assets" in the Notes to our Consolidated Financial Statements for more information regarding our 2022 impairment of long-lived assets.

***The industry in which we operate is subject to significant competition and our failure to effectively compete could have a material adverse effect on our business and results of operations.***

The hangar space rental segment of the aviation services industry in which we operate is very competitive. We compete with national, regional and local FBO and other hangar real estate companies. Competitor aircraft hangar operators at an airport compete based on various factors, including location of their facilities relative to runways and street access, service, value added features, reliability, and price. Our HBS hangar campuses compete with one or more hangar operators at their respective airports and with operators at nearby airports. Furthermore, ground leases related to HBS and FBO operations may be subject to competitive bidding at the end of their term.

Our competitors may include hangar operators currently operating at certain airports, as well as possible entrants into our market due to new entrants, consolidation, merger, modification of airport master plans, or any other number of factors. These entrants may have additional financial or other resources and/or lower cost structures than us. Other competitors have been in business longer than us. Having greater financial resources may make it easier for these competitors to absorb higher construction costs and other increases in expenses. This could impact our business and results of operations.

Our HBS hangar campuses do not have the right to be the sole provider of services at any airport. Furthermore, despite limited space for further development at certain airports, existing competitors with FBO facilities located at our current or future airports could expand their hangar facilities and additional operators of HBS could begin operations at such airports. Competitors might seek acquisitions in regions and markets competitive to us. Given the variety of factors that impact competitiveness within the HBS industry, we can give no assurance that we will be able to successfully compete, which could, in turn, result in a decline in the trading price of our securities.

***The growth and success of our business is subject to our ability to market and to attract and retain tenants.***

Our future success depends upon our ability to attract and retain tenants for hangars at our HBS hangar campuses. The extent to which we achieve growth in our customer base materially influences our business and results of operation. 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, the availability of alternative hangars, including size, location and/or services provided, as well as the external perception of us. 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.

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

***Our rental revenue is concentrated within a small number of tenants and the loss of or default by one or more significant tenants could have a material adverse effect on our business and results of operations.***

Our two largest tenants contributed a substantial portion of our revenues. Both of these tenants have ongoing leases with us that expire in December 2023 and November 2025, respectively (assuming no exercise of tenant option extensions). If any of our most significant tenants, currently or in the future, were to discontinue or otherwise reduce their use of our HBS hangar campuses or other services, our business and results of operation would be materially and adversely affected.

***Our capital projects are subject to uncertainties, including the possibility of delays, cost overruns, and inflation, which could have a material adverse effect on our business, results of operation and market reputation.***

The estimated costs of, and the projected schedule for, our capital projects are subject to a number of uncertainties. Our ability to complete these projects within budgets and on expected schedules may be adversely affected by various factors including:

● estimating errors;

● design and engineering errors;

● cost increases because of demand for labor and materials;

● contractors' difficulty in predicting costs over a lengthy construction period;

● the need to estimate costs of unbid project elements;

● changes to the scope of the projects;

● delays in contract awards;

● material and/or labor shortages;

● unforeseen site conditions;

● adverse weather conditions;

● contractor defaults and bankruptcy;

● labor disputes;

● unanticipated levels of inflation;

● litigation; and

● environmental issues.

Inflationary and supply chain pressures have led to increased construction materials costs, specifically associated with steel, concrete, and other materials. We believe we will continue to experience such pressures in future quarters, as well as delays in our contractors' ability to requisition such materials. These pressures have led to an overall increase in budgeted and actual construction costs, as well as delays in starting and completing certain of our development projects, particularly at our Centennial and Deer Valley Airport development projects. No assurance can be given that the costs of our projects will not exceed budgets or the guaranteed maximum price for such projects or that the completion will not be delayed beyond the projected completion dates. Any such cost overruns or delays could have a material adverse effect on our business, results of operations or market reputation, which could, in turn, result in a decline in the value of our Common Stock.

***Failure to adequately maintain our HBS hangar campuses or the integrity of our fuel supplies may have a material adverse impact on the revenue or market share of one or more of our HBS hangar campuses resulting in a decline in operations of the business.***

HBS and FBO operators compete, in part, based on the overall quality and attractiveness of their facilities. Inadequate maintenance of any of the hangars or other assets comprising our HBS hangar campuses could result in customers' electing not to utilize us where another provider operates, or to elect not to use a particular airport where an alternative operator in the same market exists. The resulting decline in tenants or negative impact on our reputation could adversely impact revenue, including from more than one facility, which would have a material adverse effect on our business and results of operation.

Aircraft owners and operators rely on HBS and FBO operators to control the quality of the fuel they provide. Failure to maintain the integrity of fuel supplies as a result of inadequate or inappropriate procedures or maintenance of fuel storage facilities, fuel trucks or related equipment on our part or our suppliers, including FBOs, could result in the introduction of contaminants and could lead to damage or failure of aircraft and could adversely impact the reputation, revenue, and/or profitability of our business.

***The growth and success of our business is dependent on the continued service of certain key employees and the ability to recruit and retain new employees.***

We are dependent on the continued availability of the services of our employees, many of whom are individually key to our current and future success, as well as the availability of new employees to implement our development plans. Because our management team and key employees are not obligated to provide us with continued service, they could terminate their employment with us at any time.

In addition, the market for employees is highly competitive, especially for employees in fields such as aviation and real estate. While our compensation programs are intended to attract and retain the employees required for us to be successful, ultimately, we may not be able to retain the services of all of our key employees or a sufficient number to execute our development plans. In addition, we may not be able to continue to attract new employees as required. In the event we are unable to attract and retain talent sufficient to support our development plans, our business and results of operations may be adversely affected.

***Our management team has no prior experience operating a public company, and we cannot assure you that the past experience of our senior management team will be sufficient to successfully operate as a public company.***

While certain members of our senior management team and directors have extensive experience in real estate, aviation, development, management and finance, no members of our senior management team and Board of Directors have prior experience in operating a public company. As a public company, we are required to develop and implement substantial control systems, policies and procedures in order to satisfy the company's periodic SEC reporting. We cannot assure you that management's past experience will be sufficient to successfully develop and implement these systems, policies and procedures and to operate a public company, which could have a material adverse effect on our business, results of operation, and value of our Class A Common Stock.

***We are not required to have our outside auditor attest to the effectiveness of our internal controls for several years. If we fail to maintain effective internal control over financial reporting, we may not be able to accurately report our financial results, which may adversely affect investor confidence in the Company and, as a result, the value of our Common Stock.***

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Substantial work on our part is required to implement appropriate processes, document the system of internal control over key processes, assess their design, remediate any deficiencies identified and test their operation. This process is expected to be both costly and challenging. As of such time that we are no longer an emerging growth company or a non-accelerated filer and smaller reporting company, Section 404 of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") will require our auditors to deliver an attestation report on the effectiveness of our internal control over financial reporting in conjunction with their opinion on our audited financial statements. As a result, there would likely be no outside auditor attestation report on our internal controls over financial reporting for the fiscal years through 2024. We will be required to evaluate our status as a smaller reporting company on an annual basis.

We cannot give any assurances that material weaknesses will not be identified in the future in connection with our compliance with the provisions of Section 404 of the Sarbanes-Oxley Act. The existence of any material weakness would preclude a conclusion by management and our independent auditors that we maintained effective internal control over financial reporting. Our management may be required to devote significant time and expense to remediate any material weaknesses that may be discovered and may not be able to remediate any material weakness in a timely manner. The existence of any material weakness in our internal control over financial reporting could also result in errors in our financial statements that could require us to restate our financial statements, cause us to fail to meet our reporting obligations and cause investors to lose confidence in our reported financial information, all of which could lead to a decline in the value of our Common Stock.

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

***We conduct substantially all of our operations under ground leases, which grant significant rights to airport authorities as our direct or ultimate landlord. The termination for cause of one or more of the ground leases would affect our business and results of operations significantly.***

We do not directly own the sites we develop and lease to tenants. Instead, we enter into ground leases at each site directly or indirectly (thru a sub-lessor) from airport authorities and other governmental agencies that regulate local airports. Airport authorities may choose not to renew a lease at all or to only renew the lease on terms that are unfavorable to us. In addition, airport authorities may require us to participate in a bidding process to renew a lease, which could require unanticipated capital spending and could divert management's attention during the pendency of the process. The loss or modification of any of our airport ground leases could adversely impact our business and results of operations.

***Because we do not directly own the sites we lease, we will not be able to liquidate real estate investments in order to meet liquidity needs.***

Unlike other real estate companies that lease space to tenants, we do not directly own the sites we lease. Instead, the sites are subject to long-term ground leases with airport authorities. As a result, we will not be able to sell underlying real estate assets in order to meet liquidity requirements, including our debt service obligations, which could have a material and adverse impact on our liquidity position and ability to meet our obligations.

***We may be unable to renew ground leases, lease vacant space or re-lease space as leases expire, or renewing existing leases may require significant concession, inducements and/or capital expenditures.***

We cannot assure you that our airport ground leases will be renewed or that our hangars will be re-leased at rental rates equal to or above the current average rental rates or that we will not offer substantial concessions or below-market renewal options to attract new tenants or retain existing tenants.

If the rental rates for our hangar campuses decrease, or if our existing tenants do not renew their leases or we do not re-lease a significant portion of our available space and space for which leases will expire, our business and results of operations could be adversely affected. In order to attract and retain tenants, we may be required to make rent or other concessions to tenants, accommodate requests for renovations and other improvements or provide additional services to our tenants. Additionally, we may need to raise capital to make such expenditures. If we are unable to do so or if capital is otherwise unavailable, we may be unable to make the required expenditures. This could result in non-renewals by tenants upon expiration of their leases and/or an inability to attract new tenants, which would have a material adverse effect on our business and results of operation.

***Failure to succeed in new markets may have adverse consequences.***

We intend to continue to develop properties across the United States. When we develop properties located in new geographic areas in the United States, we may face risks associated with a lack of market knowledge or understanding of the local market, including the availability and identity of quality tenants, forging new business relationships in the area, and developing an understanding of local government requirements and procedures. Furthermore, the negotiation of a potential expansion into new markets may divert management time and other resources. As a result, we may have difficulties executing our business strategy in these new markets, which could have a negative impact on our business and results of operations.

***Our business and results of operations will be dependent on tenants satisfying their obligations under tenant leases, which may be subject to default or termination.***

We are subject to tenant credit risk. Our HBS hangars are generally leased to single or multi hangar tenants, and certain of our tenants constitute a significant percentage of our revenues. Therefore, the financial failure of, or other default by, a single tenant under its lease is likely to cause a significant or complete reduction in the operating cash flow generated by the property leased to that tenant. For instance, any of our tenants could experience a downturn in their businesses, which may weaken their financial condition and liquidity and result in their failure to make timely payments to us or otherwise default under their contracts.

If a tenant defaults under its lease, we may be forced to pursue alternative arrangements with those tenants in order to recover amounts due under the leases or pursue litigation in order to collect payments from tenants who are unable make their lease payments as they come due. We can provide no assurance that we will be able to collect the full amount due under a particular lease if we are forced to pursue alternative payment arrangements or litigation with any of our tenants. If the tenant represents a significant portion of our rental revenues, the impact on our business and results of operations would be material if it impacts the company's ability to pay ground lease rent payments on a timely basis.

If a bankrupt tenant rejects a lease with us, any claim we might have for breach of the lease, excluding a claim against collateral securing the lease, would be treated as a general unsecured claim. In the event of a tenant's default under its lease or its rejection of the lease in bankruptcy proceedings, we may be unable to locate a replacement tenant in a timely manner or on comparable or better terms. As a result, our financial condition and results of operations could be adversely affected.

***Our business and results of operations may be materially adversely affected by a default under a ground lease or the bankruptcy of a subsidiary.***

We are a holding company with no independent operations and, as such, will be dependent upon the operations of our subsidiaries. Our subsidiaries' operations rely upon the authority granted under certain ground leases to operate project sites. Each operating subsidiary with bond debt is structured as a special purpose entity. In the event of the bankruptcy of one or more of these subsidiaries, delays in the payment of rent, fees or loan payments may occur under the automatic stay provisions of the United States Bankruptcy Code. Moreover, a subsidiary debtor as lessee or a trustee in bankruptcy may reject a ground lease altogether, thereby extinguishing the respective subsidiary's duty to pay rent and its right to use the leased property. In addition, a subsidiary lessee may fail to make rental or fee payments when due to the respective airport landlord, regardless of its financial situation. Such bankruptcy or default of a subsidiary lessee could result in the loss of the leased property, which is critical to the operation of our business. A loss of any leased property could have a material adverse effect on our business and results of operations.

To the extent a ground lease constitutes a "true lease," a subsidiary that has executed its applicable ground lease, or other executory contract, with an airport landlord and seeks protection under the U.S. bankruptcy laws must, subject to the bankruptcy court's approval, assume or reject (a) its ground lease within 120 days after the bankruptcy filing (subject to court approval, a one-time 90-day extension is allowed (further extensions are subject to the consent of the relevant airport landlords)), and (b) its other executory contracts with the airport landlord no later than the confirmation of a plan of reorganization.

In the event of assumption and/or assumption and assignment of any executory contract with a third party, the subsidiary would be required to cure any pre- and post-petition monetary defaults and provide adequate assurance of future performance under the ground lease or other applicable agreements.

Rejection of a ground lease or other executory contract, in general, is treated as a pre-petition breach of contract. Subject to certain exceptions, this rejection relieves the subsidiary of performing future obligations under the contract, but will give rise to the tenant's loss of use of the leased property and a pre-petition general unsecured claim of the airport landlord for rejection damages, the amount of which in the case of a ground lease or other agreement is limited by the United States Bankruptcy Code generally to any amounts due and payable prior to the bankruptcy plus the greater of (a) the rent reserved by such lease, without acceleration, for one year of rent; or (b) 15% of the total remaining rent payments, not to exceed three years. However, the amount ultimately received in the event of a rejection of a ground lease or other agreement could be considerably less than the maximum amounts allowed under the United States Bankruptcy Code. In addition, payments made by a subsidiary in bankruptcy within 90 days of filing a bankruptcy case could be deemed to be an "avoidable preference" under the United States Bankruptcy Code and thus subject to recapture by the debtor-in-possession or its trustee in bankruptcy. In general, risks associated with bankruptcy include risks of substantial delay in payment or of non-payment and the risk that the airport landlord may not be able to enforce any of its remedies under the agreements with a bankrupt borrower.

During the pendency of a bankruptcy proceeding, a debtor subsidiary may not, absent a court order, make any payments to the airport landlord or to us on account of goods and services provided prior to the bankruptcy. Thus, the airport landlord or our stream of payments from a debtor subsidiary would be interrupted to the extent of pre-petition goods and services, including accrued loan and lease payments, which would have a material adverse effect on our business and results of operation.

In addition, with respect to tenant leases, under current bankruptcy law, in the event of a bankruptcy of such tenant, the tenant can generally assume or reject a lease within a certain number of days of filing its bankruptcy petition. If a tenant rejects the lease, our damages as a landlord, subject to availability of funds from the bankruptcy estate, are generally limited to the greater of (1) one year's rent and (2) the rent for 15% of the remaining term of the lease, not to exceed three years. Any such event could have a material adverse effect on our business and results of operations.

***The lack of accurate and reliable industry data can result in unfavorable strategic planning, mergers and acquisitions, and macro pricing decisions.***

We use industry and airport-specific general aviation traffic data published by the FAA, as well as data from private sources, to identify trends in the aircraft hangar industry. We also use this data as an input to decision-making, including in strategic planning and pricing matters. Both the public and private data, however, has several limitations and challenges. As a result, the use of such data may result in decisions in strategic planning or pricing that are incorrect or inefficient, which could have a material adverse effect on our business and results of operation.

***We are subject to extensive governmental regulations that could require significant expenditures. Regulators, such as the TSA, have and may again consider regulations that could impair the relative convenience of general aviation and adversely affect demand for our services.***

We are subject to extensive regulatory requirements and compliance with those requirements could result in significant costs. For example, the FAA, from time to time, issues directives and other regulations relating to the management, maintenance, and operation of airport facilities. Compliance with those requirements may cause us to incur significant expenditures.

In addition, the proposal and enactment of additional laws and regulations, including by the TSA, as well as any failure to comply with such laws and regulations, could significantly increase the cost of our operations and reduce overall revenue. Moreover, certain new regulations, if implemented, could decrease the convenience and attractiveness of general aviation travel relative to commercial air travel and may adversely impact demand for our services.

------

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

***Compliance or failure to comply with the ADA and other regulations could result in substantial costs.***

Under the ADA, places of public accommodation must meet certain federal requirements related to access and use by disabled persons. Noncompliance with these requirements could result in additional costs to attain compliance, the imposition of fines by the federal government or the award of damages or attorney's fees to private litigants. If we are required to make unanticipated expenditures to comply with the ADA or other regulations, including removing access barriers, then our business and results of operations may be adversely affected.

***Potential limitation of tax-exemption of interest on private activity bonds could impact the debt funding of Sky for future projects or significantly increase our cost.***

From time to time, the President of the United States, the United States Congress and/or state legislatures have proposed and could propose in the future, legislation that, if enacted, could cause interest on private activity bonds to be subject, directly or indirectly, to federal income taxation or to be subject to state income taxation. Clarifications of the Internal Revenue Code of 1986 (the "Code"), as amended, or court decisions may also cause interest on private activity bonds to be subject, directly or indirectly, to federal income taxation or to be subject to state income taxation. The introduction or enactment of any such legislative proposals or any clarification of the Code or court decisions may also affect the market price for, or marketability of, private activity bonds. We expect to issue private activity bonds in the future to partially fund our expansion of hangar campuses at new airport sites. Lack of access to private activity bonds due to change in law or market access would have an increase in the cost of our debt and our future financial results.

***Uninsured losses or a loss in excess of insured limits could adversely affect our business and results of operations.***

We carry comprehensive liability, fire, property damage, and business interruption insurance on our HBS hangar campuses, with policy specifications and insured limits that we believe are customary for similar properties. An unanticipated number of claims under the insurance policy or policies, however, could result in payment of unanticipated deductibles and increased premiums, which could result in a material adverse effect on our business and results of operations.

As with all real estate, if reconstruction (for example, following fire or other casualty) or any major repair or improvement is required to the damaged property, changes in laws and governmental regulations may be applicable and may materially affect the cost to, or ability of, us to affect such reconstruction, major repair or improvement. In addition, there can be no assurance that the amount of insurance required or provided would be sufficient to cover damages caused by any casualty, or that such insurance will be commercially available in the future.

There can also be no assurance that any loss incurred will be of a type covered by such insurance and will not exceed the limits of such insurance. For instance, there are certain types of losses, such as losses resulting from wars, terrorism or certain acts of God, that generally are not insured because they are either uninsurable or not economically insurable. Should an uninsured loss or a loss in excess of insured limits occur, we could suffer disruption of rental income, potentially for an extended period of time, while remaining responsible for any financial obligations relating to the applicable HBS hangar campus, which would have a material adverse effect on our business and results of operations.

***We may not be able to rebuild our properties to their existing specifications if we experience a substantial or comprehensive loss of such properties.***

In the event that we experience a substantial or comprehensive loss of one of our properties, we may not be able to rebuild such property to its existing specifications. Further, reconstruction or improvement of such a property may require significant upgrades to meet zoning and building code requirements. Environmental and legal restrictions could also restrict the rebuilding of properties.

***Our businesses are subject to environmental risks that may impact our future profitability.***

Our businesses are subject to numerous statutes, rules and regulations relating to environmental protection and we are exposed to various environmental risk and hazards, including the environmental protection requirements related to the storage and handling of jet fuel and compliance with firefighting regulations. Materialization of these risks could result in substantial losses including personal injury, loss of life, damage or destruction of property and equipment, and environmental damage. Any losses we face could be greater than insurance levels maintained by our businesses and could have an adverse effect on us and our businesses and results of operations. We also could be subject to fines and penalties for violation of applicable environmental regulations, which could be substantial. In addition, disruptions to physical assets could reduce our ability to serve customers and adversely affect future rentals, services and cash flows.

Failure to comply with regulations or other claims may interrupt operations and result in civil or criminal penalties, significant unexpected compliance costs and liabilities that could adversely affect the profitability of our business. These rules and regulations are subject to change, and compliance with any changes could result in a restriction of the activities of our businesses, significant capital expenditures, and/or increased ongoing operating costs.

We may also be required to address other prior or future environmental contamination, including soil and groundwater contamination that results from the spillage of fuel, hazardous materials, or other pollutants. Any past contamination of the properties could result in remediation obligations, personal injury, property damage, environmental damage, or similar claims by third parties.

Under various federal, state, and local environmental statutes, rules and regulations, a current or previous owner or operator of real property may be liable for noncompliance with applicable environmental and health and safety requirements and for the costs of investigation, monitoring, removal or remediation of hazardous materials. These laws often impose liability, whether the current owner or operator knew of, or was responsible for, the presence of hazardous materials. Persons who arrange for the disposal or treatment of hazardous materials may also be liable for the costs of removal or remediation of those materials at the disposal or treatment facility, whether or not that facility is or ever was owned or operated by that person and whether or not the original disposal or treatment activity accorded with all regulatory requirements. The presence of hazardous materials on a property could result in personal injury, loss of life, damage or destruction of property and equipment, environmental damage and/or claims by third parties that could have a material adverse effect on our business and results of operations.

***We are exposed to the potential impacts of future climate change and climate change-related risks.***

Our properties may be exposed to rare catastrophic weather events, such as severe storms, floods or wildfires. If the frequency of extreme weather events increases due to climate change, our exposure to these events could increase. In addition, in connection with any development project, we may be harmed by potential changes to the supply chain or stricter energy efficiency standards for industrial buildings. To the extent climate change causes shifts in weather patterns, our markets could experience negative consequences, including declining demand for hangar space and an inability to operate our hangar campuses. Climate change may also have indirect negative effects on our business by increasing the cost of, or decreasing the availability of, property insurance on terms we find acceptable and increasing the cost of, among other things, energy, aircraft fuel and building materials.

In addition, compliance with new laws or regulations relating to climate change, including compliance with "green" building codes, may require us to make improvements to our existing properties or result in increased operating costs that we may not be able to effectively pass on to our tenants. Any such laws or regulations could also impose substantial costs on our tenants, thereby impacting the financial condition of our tenants and their ability to meet their lease obligations.

***Cybersecurity risks and cyber incidents may adversely affect our business by causing a disruption to our operations, a compromise or corruption of our confidential information, misappropriation of assets and/or damage to our business relationships, all of which could negatively impact our business and results of operations.***

Cyber incidents may result in disrupted operations, misstated or unreliable financial data, liability for stolen assets or information, increased cybersecurity protection and insurance costs and litigation and damage to our tenants. As our reliance on technology has increased, so have the risks posed to our information systems, both internal and those we have outsourced. Any processes, procedures and internal controls that we implement, as well as our increased awareness of the nature and extent of a risk of a cyber-incident, do not guarantee that our financial results, operations, business relationships, confidential information or Common Stock price will not be negatively impacted by such an incident.

Insider or employee cyber and security threats are increasingly a concern for all companies, including us. In addition, social engineering and phishing are a particular concern for companies with employees. As a landlord, we are also susceptible to cyber-attacks on our tenants and their payment information. We are continuously working to deploy information technology systems and to provide employee awareness training around phishing, malware and other cyber risks to ensure that we are protected against cyber risks and security breaches. Such technology and training, however, may not be sufficient to protect us and our tenants from all risks.

As a smaller company, we use third-party vendors to assist us with our network and information technology requirements. While we carefully select these third-party vendors, we cannot control their actions. Any problems caused by these third parties, including those resulting from breakdowns or other disruptions in communication services provided by a vendor, failure of a vendor to handle current or higher volumes, cyber-attacks and security breaches at a vendor could adversely affect our business and results of operations.

We may not be able to adequately address these additional risks. If we were unable to do so, our operations might suffer, which may adversely impact our results of operations and financial condition.

**Risks Relating to Our Organization and Structure**

***We are a*** "***controlled company***" ***within the meaning of the NYSE American listing standards and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements. You do not have the same protections afforded to stockholders of companies that are subject to such requirements.***

We qualify as a "controlled company" within the meaning of the corporate governance standards of the NYSE American. Under these rules, a listed company of which more than 50% of the voting power is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements, including the requirement that (i) a majority of the our Board consist of independent directors, (ii) our compensation committee is composed entirely of independent directors and (iii) director nominees be selected or recommended to our Board by independent directors.

We rely on certain of these exemptions. As a result, we do not have a compensation committee consisting entirely of independent directors and our directors are not nominated or selected solely by independent directors. We may also rely on the other exemptions so long as we qualify as a controlled company. To the extent we rely on any of these exemptions, holders of Class A Common Stock will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the NYSE American.

***The Existing Sky Equityholders control the direction of SHG Corporation***'***s business, and the concentrated ownership of Common Stock prevent you and other stockholders from influencing significant decisions.***

In connection with the Business Combination, we, each of Tal Keinan, Due West Partners LLC and Center Sky Harbour LLC (collectively, "the Existing Sky Equityholders"), and the Sponsor (collectively the "Stockholder Parties") entered into a stockholders' agreement (the "Stockholders' Agreement"). Pursuant to the terms of the Stockholders' Agreement, each of the parties thereto are required to take all necessary action to cause the specified designees of the Existing Sky Equityholders to be nominated to serve on our Board, and each of the holders are required, among other things, to vote all of the securities of SHG Corporation held by such party in a manner necessary to elect the individuals designated by such holders. For so long as these parties hold a majority of Common Stock, they will be able to control the composition of our Board, which in turn will be able to control all matters affecting us, subject to the terms of the Stockholders' Agreement, including:

● any determination with respect to our business direction and policies, including the appointment and removal of officers and, in the event of a vacancy on our Board, additional or replacement directors;

● any determinations with respect to mergers, business combinations or disposition of assets;

● determination of our management policies;

● our financing policy;

● our compensation and benefit programs and other human resources policy decisions; and

● the payment of dividends on Common Stock.

Because the interests of these stockholders may differ from our interests or the interests of our other stockholders, actions that these stockholders take with respect to us may not be favorable to us or our other stockholders.

***Provisions in our Bylaws and Delaware law may have the effect of discouraging lawsuits against our directors and officers.***

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

***We qualify as an*** "***emerging growth company***" ***within the meaning of the Securities Act, and we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, and as such, it could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.***

We qualify as an "emerging growth company" as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012 (the "JOBS Act"). As such, we are eligible for and we take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as it continues to be an emerging growth company, including, but not limited to, (i) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, (ii) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and (iii) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year (a) following the fifth anniversary of the completion of the Business Combination, (b) in which we have total annual gross revenue of at least $1.235 billion, or (c) in which we are is deemed to be a large accelerated filer, which means the market value of our Common Stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three year period. We cannot predict whether investors will find our securities less attractive because it will rely on these exemptions. If some investors find our securities less attractive as a result of its reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

***Because members of our senior management team hold most or all of their economic interest in Sky through other entities, conflicts of interest may arise between them and holders of shares of Class A Common Stock or us.***

Because members of our senior management team hold most or all of their economic interest in Sky directly through holding companies, they may have interests that do not align with, or conflict with, those of the holders of Class A Common Stock or with us. For example, members of our senior management team may have different tax positions from those of SHG Corporation and/or holders of Class A Common Stock, which could influence their decisions regarding whether and when to enter into certain transactions or dispose of assets, whether and when to incur new or refinance existing indebtedness, and whether and when we should terminate the Tax Receivable Agreement and accelerate the obligations thereunder. In addition, the structuring of future transactions and investments may take into consideration the members' tax considerations even where no similar benefit would accrue to SHG Corporation.

***The requirements of being a public company may strain our resources and divert management***'***s attention.***

As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the NYSE American and other applicable securities rules and regulations. Compliance with these rules and regulations increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources, particularly after we are no longer an "emerging growth company." The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management's attention may be diverted from other business concerns, which could adversely affect our business and operating results. We may need to hire more employees in the future or engage outside consultants to comply with these requirements, which will increase our costs and expenses.

**Risks Relating to Tax**

***Our only principal asset is our interest in Sky, and accordingly we will depend on distributions from Sky to pay dividends, taxes, other expenses, and make any payments required to be made by us under the Tax Receivable Agreement.***

We are a holding company and have no material assets other than our ownership of Sky Common Units. We are not expected to have independent means of generating revenue or cash flow, and our ability to pay our taxes, operating expenses, and pay any dividends in the future will be dependent upon the financial results and cash flows of Sky. There can be no assurance that Sky will generate sufficient cash flow to distribute funds to us or that applicable state law and contractual restrictions, including negative covenants under debt instruments will permit such distributions. If Sky does not distribute sufficient funds to us to pay our taxes or other liabilities, we may default on contractual obligations or have to borrow additional funds. In the event that we are required to borrow additional funds, it could adversely affect our liquidity and subject us to additional restrictions imposed by lenders.

Sky is treated as partnership for U.S. federal income tax purposes and, as such, generally is not subject to any entity-level U.S. federal income tax. Instead, taxable income will be allocated, for U.S. federal income tax purposes, to the holders Sky Common Units. Under the terms of the third amended and restated Operating Agreement (the " A&R Operating Agreement"), Sky is obligated to make pro rata tax distributions to holders of Sky Common Units calculated at certain assumed rates. In addition to tax expenses, we will also incur expenses related to our operations, including payment obligations under the Tax Receivable Agreement, which could be significant and some of which will be reimbursed by Sky (excluding payment obligations under the Tax Receivable Agreement). For so long as we are Managing Member (as defined in the A&R Operating Agreement) of Sky, we intend to cause Sky to make ordinary distributions and tax distributions to the holders of Sky Common Units on a pro rata basis in amounts sufficient to enable us to cover all applicable taxes, relevant operating expenses, payments under the Tax Receivable Agreement and dividends, if any, declared by us. However, Sky's ability to make such distributions may be subject to various limitations and restrictions, including, but not limited to, retention of amounts necessary to satisfy the obligations of Sky and its subsidiaries and restrictions on distributions that would violate any applicable restrictions contained in Sky's debt agreements, or any applicable law, or that would have the effect of rendering Sky insolvent. To the extent we are unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid. Additionally, nonpayment for a specified period and/or under certain circumstances may constitute a material breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments under the Tax Receivable Agreement, which could be substantial.

------

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

We anticipate that the distributions received from Sky may, in certain periods, exceed our actual tax liabilities and obligations to make payments under the Tax Receivable Agreement. The Board, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, which may include, among other uses, to pay dividends on our Class A Common Stock. We will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders.

***The Tax Receivable Agreement requires us to make cash payments to the TRA Holders in respect of certain tax benefits and such payments may be substantial. In certain cases, payments under the Tax Receivable Agreement may (i) exceed any actual tax benefits the Tax Group realizes or (ii) be accelerated.***

Following closing of the Business Combination, we, Sky, the Existing Sky Equityholders and Tal Keinan (in the capacity of "TRA Holder Representative") entered into the Tax Receivable Agreement. Pursuant to the Tax Receivable Agreement, we are generally required to pay the TRA Holders 85% of the amount of savings, if any, in U.S. federal, state, local, and foreign taxes that are based on, or measured with respect to, net income or profits, and any interest related thereto that the Tax Group (i.e., SHG Corporation and applicable consolidated, unitary, or combined Subsidiaries) realizes, or is deemed to realize, as a result of certain Tax Attributes, which include:

● existing tax basis in certain assets of Sky and certain of its direct or indirect Subsidiaries, including assets that will eventually be subject to depreciation or amortization, once placed in service, attributable to Sky Common Units acquired by SHG Corporation from a TRA Holder, as determined at the time of the relevant acquisition;

● tax basis adjustments resulting from taxable exchanges of Sky Common Units (including any such adjustments resulting from certain payments made by SHG Corporation under the Tax Receivable Agreement) acquired by SHG Corporation from a TRA Holder pursuant to the terms of the A&R Operating Agreement; and

● tax deductions in respect of portions of certain payments made under the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement generally will be based on the tax reporting positions that we determine (with the amount of subject payments determined in consultation with an advisory firm and subject to the TRA Holder Representative's review and consent), and the Internal Revenue Service (the "IRS") or another taxing authority may challenge all or any part of a position taken with respect to tax attributes or the utilization thereof, as well as other tax positions that we take, and a court may sustain such a challenge. In the event that any tax attributes initially claimed or utilized by the tax group are disallowed, the TRA Holders will not be required to reimburse us for any excess payments that may previously have been made pursuant to the Tax Receivable Agreement, for example, due to adjustments resulting from examinations by taxing authorities. Rather, any excess payments made to such TRA Holders will be applied against and reduce any future cash payments otherwise required to be made by us to the applicable TRA Holders under the Tax Receivable Agreement, after the determination of such excess. However, a challenge to any tax attributes initially claimed or utilized by the tax group may not arise for a number of years following the initial time of such payment and, even if challenged earlier, such excess cash payment may be greater than the amount of future cash payments that we might otherwise be required to make under the terms of the Tax Receivable Agreement. As a result, there might not be future cash payments against which such excess can be applied and we could be required to make payments under the Tax Receivable Agreement in excess of the tax group's actual savings in respect of the tax attributes.

Moreover, the Tax Receivable Agreement will provide that, in certain early termination events, we will be required to make a lump-sum cash payment to all the TRA Holders equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement. The lump-sum payment would be based on certain assumptions, including those relating to there being sufficient future taxable income of the tax group to fully utilize the tax attributes over certain specified time periods and that all Sky Common Units that had not yet been exchanged for Class A Common Stock or cash are deemed exchanged for cash. The lump-sum payment could be material and could materially exceed any actual tax benefits that the tax group realizes subsequent to such payment.

Payments under the Tax Receivable Agreement will be our obligations and not obligations of Sky. Any actual increase in our allocable share of Sky and its relevant subsidiaries' tax basis in relevant assets, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of exchanges, the market price of the Class A Common Stock at the time of an exchange of Sky Common Units by a TRA Holder pursuant to the terms of the A&R Operating Agreement and the amount and timing of the recognition of the Tax Group's income for applicable tax purposes. While many of the factors that will determine the amount of payments that we will be required to make under the Tax Receivable Agreement are outside of our control, we expect that the aggregate payments we will be required to make under the Tax Receivable Agreement could be substantial and, if those payments substantially exceed the tax benefit we realize in a given year or in the aggregate, could have an adverse effect on our financial condition, which may be material.

Any payments made by us under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to us. To the extent that we are unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid. Additionally, nonpayment for a specified period and/or under certain circumstances may constitute a material breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments due under the Tax Receivable Agreement. Furthermore, our future obligation to make payments under the Tax Receivable Agreement could make us a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the Tax Attributes that may be deemed realized under the Tax Receivable Agreement.

***We could be adversely affected by changes in applicable tax laws, regulations, or administrative interpretations thereof in the United States or other jurisdictions*.**

We could also be adversely affected by changes in applicable tax laws, regulations, or administrative interpretations thereof in the United States or other jurisdictions and changes in tax law could reduce our after-tax income and adversely affect our business and financial condition. For example, the U.S. federal tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "**Tax Act**"), enacted in December 2017, resulted in fundamental changes to the Code. These changes included, among many other things, a reduction to the federal corporate income tax rate, a partial limitation on the deductibility of business interest expense, a limitation on the deductibility of certain director and officer compensation expense, limitations on net operating loss carrybacks and carryovers and changes relating to the scope and timing of U.S. taxation on earnings from international business operations. Subsequent legislation, the Coronavirus Aid, Relief, and Economic Security Act (the "**CARES Act**") enacted on March 27, 2020, relaxed certain of the limitations imposed by the Tax Act for certain taxable years, including the limitation on the use and carryback of net operating losses and the limitation on the deductibility of business interest expense. The exact impact of the Tax Act and the CARES Act for future years is difficult to quantify, but these changes could materially affect SHG Corporation, Sky, or its subsidiaries. In addition, other changes could be enacted in the future to increase the corporate tax rate, limit further the deductibility of interest, or effect other changes that could have a material adverse effect on SHG Corporation's financial condition. Such changes could also include increases in state taxes and other changes to state tax laws to replenish state and local government finances depleted by costs attributable to the COVID-19 pandemic and the reduction in tax revenues due to the accompanying economic downturn.

More recently, the United States government has recently enacted the Inflation Reduction Act of 2022 which, among other things, significantly changes the taxation of business entities including by imposing a minimum tax equal to fifteen percent of the adjusted financial statement income of certain corporations as well as a one percent excise tax on share buybacks, effective for tax years beginning in 2023. When effective, it is possible that the minimum tax could result in an additional tax liability over the regular federal corporate tax liability in a given year based on differences between book and taxable income (including as a result of temporary differences). The resulting tax liability could adversely impact SHG Corporation's business, financial condition, results of operation and liquidity. The excise tax on share buybacks is currently not expected to have a material impact on SHG Corporation's tax liability.

In addition, our effective tax rate and tax liability are based on the application of current income tax laws, regulations and treaties. These laws, regulations and treaties are complex and often open to interpretation. In the future, the tax authorities could challenge our interpretation of laws, regulations and treaties, resulting in additional tax liability or adjustment to our income tax provision that could increase our effective tax rate. Changes to tax laws may also adversely affect our ability to attract and retain key personnel.

**Risks Relating to Our Common Stock and Warrants**

***The market price of Class A Common Stock and Public Warrants has been and may continue to be extremely volatile, which could cause purchasers of our securities to incur substantial losses.***

The market prices and trading volume that our shares of Class A Common Stock have recently experienced, and may continue to experience, extreme volatility, which could cause purchasers of our Class A Common Stock and Public Warrants to incur substantial losses. Since the closing of the Business Combination, our Class A Common Stock has traded as low as $2.50 and as high as $43.41 through December 31, 2022. In addition, the volume of trading of our Class A Common Stock has been inconsistent. For example, on February 16, 2022 our Class A Common Stock had trading volume of 13,800 shares and on February 18, 2022 our Class A Common Stock had trading volume of 19,692,800. Our Public Warrants have not traded in tandem with our Class A Common Stock, and since the closing of the Business Combination have traded within a range of $0.18 to $2.75 through December 31, 2022.

We believe that the recent volatility and our current market prices reflect market and trading dynamics unrelated to our underlying business, or macro or industry fundamentals, and we do not know how long these dynamics will last. Under the circumstances, investors in our Class A Common Stock and Warrants are subject to the risk of losing all or a substantial portion of their investment.

Extreme fluctuations in the market price of our Class A Common Stock have been accompanied by reports of strong and atypical retail investor interest, including on social media and online forums. The market volatility and trading patterns we have experienced create several risks for investors, including the following:

● the market price of our Class A Common Stock has experienced and may continue to experience rapid and substantial increases or decreases unrelated to our operating performance or prospects, or macro or industry fundamentals, and substantial increases may be significantly inconsistent with the risks and uncertainties that we continue to face;

● factors in the public trading market for our Class A Common Stock may include the sentiment of retail investors, the direct access by retail investors to broadly available trading platforms, the amount and status of short interest in our securities, access to margin debt, trading in options and other derivatives on our Class A Common Stock and any related hedging and other trading factors;

● to the extent volatility in our Class A Common Stock is caused by a "short squeeze" in which coordinated trading activity causes a spike in the market price of our Class A Common Stock as traders with a short position make market purchases to avoid or to mitigate potential losses, investors purchase at inflated prices unrelated to our financial performance or prospects, and may thereafter suffer substantial losses as prices decline once the level of short-covering purchases has abated; and

● if the market price of our Class A Common Stock declines, you may be unable to resell your shares at or above the price at which you acquired them, and the Warrant you own may become out of the money.

The trading price of Class A Common Stock and Public Warrants depends on many factors, including those described in this "Risk Factors" section, many of which are beyond our control and may not be related to our operating performance. Any of the factors listed below could have a material adverse effect on investment in Class A Common Stock and Public Warrants, and Class A Common Stock and Public Warrants may trade at prices significantly below the price paid for them. In such circumstances, the trading price of Class A Common Stock and Public Warrants may not recover and may experience a further decline. Factors affecting the trading price of Class A Common Stock and Public Warrants may include:

● actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

● changes in the market's expectations about our operating results;

● the public's reaction to our press releases, our other public announcements and our filings with the SEC;

● speculation in the press or investment community;

● actual or anticipated developments in our business or our competitors' businesses or the competitive landscape generally;

● our operating results failing to meet the expectation of securities analysts or investors in a particular period;

● changes in financial estimates and recommendations by securities analysts concerning us or the market in general;

● operating and stock price performance of other companies that investors deem comparable to us;

● publications of research reports by securities analysts about us, our competitors, or the industry we operate in;

● changes in laws and regulations affecting our business;

● commencement of, or involvement in, litigation involving us;

● changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

● the volume of Class A Common Stock available for public sale;

● any major change in the Board of Directors or management;

● sales of substantial amounts of Class A Common Stock by directors, officers or significant stockholders or the perception that such sales could occur;

● general economic and political conditions such as recessions, interest rates, fuel prices, trade wars, pandemics (such as COVID-19), epidemics, currency fluctuations and acts of war (such as the conflict between Russia and Ukraine) or terrorism; and

● other risk factors listed under this "Risk Factors" section.

***The public float of our Class A Common Stock is very illiquid, and there may not be sufficient demand in the marketplace to absorb the sale of newly registered shares.***

As of December 31, 2022, the public float of our Class A Common Stock listed in the NYSE American was approximately $4.1 million, which is only 2.7% of the equity capitalization of the Company. Given the company is recently listed, and does not have any investor research coverage nor a seasoned established institutional investor base, any significant sale of newly registered shares may have a significant negative impact on the price of our Class A Common Stock.

***We cannot predict the impact our dual class structure may have on the stock price of Class A Common Stock.***

We cannot predict whether our dual class structure will result in a lower or more volatile market price of Class A Common Stock or in adverse publicity or other adverse consequences. For example, certain index providers have announced restrictions on including companies with multiple-class share structures in certain of their indexes. Under these policies, our dual class capital structure would make us ineligible for inclusion in certain indices, and as a result, mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track those indices will not be investing in our stock. It is unclear what effect, if any, these policies will have on the valuations of publicly traded companies excluded from such indices, but it is possible that they may depress valuations, as compared to similar companies that are included. As a result, the market price of shares of Class A Common Stock could be adversely affected.

***The outstanding Warrants are exercisable for shares of Class A Common Stock and common units in Sky may be redeemed for Class A Common Stock. The exercise of these outstanding warrants will increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.***

As of December 31, 2022, there were 6,799,189 outstanding Public Warrants to purchase 6,799,189 shares of Class A Common Stock at an exercise price of $11.50 per share. In addition, as of December 31, 2022, there were 7,719,779 Private Placement Warrants outstanding exercisable for 7,719,779 shares of Class A Common Stock at an exercise price of $11.50 per share. To the extent such warrants are exercised, additional shares of Class A Common Stock will be issued, which will result in dilution to the holders of Class A Common Stock and increase the number of shares eligible for resale in the public market.

In addition, as of December 31, 2022, there were 42,192,250 Sky Common Units, which may be redeemed for shares of our Class A Common Stock on a one-for-one basis, and in connection with the redemption of such Sky Common Units, the corresponding shares of Class B Common Stock will be cancelled. The lock-up period for the outstanding shares of Class B Common Stock, and for the shares of Class A Common Stock underlying the Private Placement Warrants, expired on January 25, 2023. Furthermore, we have registered for resale all of the Class A Common Stock underlying such outstanding units. Sales of substantial numbers of such shares in the public market, or the perception that such sales may occur, could adversely affect the market price of Class A Common Stock, the impact of which is increased as the value of our stock price increases.

***We do not intend to pay cash dividends for the foreseeable future.***

We currently intend to retain our future earnings, if any, to finance the further development and expansion of our business and do not intend to pay cash dividends in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board and will depend on our financial condition, results of operations, capital requirements, restrictions contained in future agreements and financing instruments, business prospects and such other factors as our Board deems relevant.

***If analysts do not publish research about our business or if they publish inaccurate or unfavorable research, our stock price and trading volume could decline.***

The trading market for Class A Common Stock will depend in part on the research and reports that analysts publish about our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our Class A Common Stock or publish inaccurate or unfavorable research about our business, the price of Class A Common Stock would likely decline. If few analysts cover us, demand for Class A Common Stock could decrease and our Class A Common Stock price and trading volume may decline. Similar results may occur if one or more of these analysts stop covering us in the future or fail to publish reports on us regularly.

***You may experience future dilution as a result of future equity issuances.***

In order to raise additional capital, we may in the future offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price per share paid by any investor. For example, on August 18, 2022, we entered into a Common Stock Purchase Agreement and a Registration Rights Agreement (collectively, the "Stock Purchase Agreement") with B. Riley Principal Capital II, LLC ("B. Riley") pursuant to which we may issue from time to time up to 10,000,000 shares of our Class A Common Stock. We will have discretion over the prices at which we sell shares under the Stock Purchase Agreement over its 36-month term. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by any investor, and investors purchasing shares or other securities in the future could have rights superior to you. The price per share at which we sell additional shares of our Common Stock, or securities convertible or exchangeable into Common Stock, in future transactions may be higher or lower than the price per share paid by any investor.

***We may be subject to securities litigation, which is expensive and could divert management attention.***

The market price of Class A Common Stock has been and may continue to be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert management's attention from other business concerns, which could seriously harm our business.

***Market Information***<br>

(a) **Market Information** 

The Company's Class A Common Stock and Public Warrants are listed on the NYSE American under the symbols "SKYH" and "SKYH WS," respectively. Prior to the consummation of the Business Combination, YAC's Units, YAC's Class A Common Stock and YAC's Public Warrants were listed on the NASDAQ Capital Market under the symbols "YSACU", "YSAC" and "YSACW," respectively. Upon consummation of the Business Combination, YAC's Units automatically separated into the component securities, YAC's Class A Common Stock was reclassified as our Class A Common Stock and YAC's Public Warrants were reclassified as our Public Warrants.

As of December 31, 2022, there were five holders of record of Class A Common Stock and three holders of record of Warrants. However, because many of the shares of Class A Common Stock and the Warrants are held by brokers and other institutions on behalf of stockholders, the Company believes there are substantially more beneficial holders of Class A Common Stock and Warrants than record holders.

(b) **Dividends** 

We have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends in the foreseeable future. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of any Business Combination. The payment of any cash dividends subsequent to our Business Combination will be within the discretion of our Board at such time. In addition, our Board is not currently contemplating and does not anticipate declaring any stock dividends in the foreseeable future. Further, if we incur any indebtedness in connection with our Business Combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

*The following discussion and analysis of the Company*'*s financial condition and results of operations should be read in conjunction with our audited financial statements and the notes related thereto which are included in* "*Item 8. Financial Statements and Supplementary Data*" *of this Annual Report on Form 10-K. Certain information contained in the discussion and analysis set forth below includes forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under* "*Special Note Regarding Forward-Looking Statements,*" "*Item 1A. Risk Factors*" *and elsewhere in this Annual Report on Form 10-K.*

**Overview and Background**

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

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

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

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

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

For a more complete description of our operations, including our HBS hangar campus development projects, refer to *Item 1 — Business*.

**Recent Developments**

On October 27, 2022, we substantially completed the construction of our BNA Phase II development project. The total construction costs incurred associated with the project were slightly less than our initial estimated construction costs. In connection with the substantial completion of our BNA HBS hangar campus, certain tenant leases associated with our constructed hangars commenced starting in November 2022.

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

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

On March 22, 2023, we satisfied the requirements within the Series 2021 PABs indenture to fund construction costs associated with our ADS Phase I development project with proceeds received from our Series 2021 PABs. See "*Note 18 — Subsequent Events — Series 2021 PABs Scope Modification*" in the Notes to Consolidated Financial Statements for additional information regarding the modification of the scope of our Series 2021 PABs. The approval and exercise of such rights will allow approximately $26 million of proceeds to be used to fund the ADS Phase I development project, and is projected to improve our debt service coverage associated with the Series 2021 PABs.

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

***Revenues***

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

***Operating Expense***

One of our largest expenses are the lease payments payable under our ground leases. For the years ended December 31, 2022 and 2021, our operating expense related to ground leases was $3.7 million and $3.7 million, respectively. As we enter into new ground leases at new airport sites, our payments to airport landlords will continue to increase into the future. If airport landlords increase the per acre cost of the ground lease of our target campuses, the operating margins at potential target developments may be impacted negatively.

***Interest Expense***

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

***General and Administrative Expenses***

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

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

***Construction Material Costs and Labor***

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

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

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

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

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

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

We consummated the Yellowstone Transaction on January 25, 2022, to raise additional equity capital to, along with potential future debt and further equity issuances, begin to fund additional airport campuses and reach up to 20 airport campuses over the next several years. On average, each future campus is anticipated to be composed of an average of 10-20 hangars and is expected to cost approximately $55 million per campus, with 60% or more to be funded with additional public activity bonds. All these future hangar campus projects are discretionary and require us to identify the appropriate airports with the target hangar demand economics, secure required ground leases and permits, and complete future construction at such sites.

The cumulative 20 airport site business plan is estimated to cost approximately $1.2 billion, with approximately 65% to 75% anticipated from long-term private activity bonds and the balance with equity or equity linked financing. The equity portion of this business plan has been partially funded upon the closing of the Yellowstone Transaction, which included an additional $45 million equity investment from Boston Omaha through the BOC PIPE. Our ability to raise additional equity and/or debt financing will be subject to a number of risks, including our ability to obtain financing upon reasonable terms, if at all, costs of construction, delays in constructing new facilities, operating results, and other risk factors. In the event that we are unable to obtain additional financing, we may be required to raise additional equity capital, creating additional dilution to existing stockholders. There can be no assurance that we would be successful in raising such additional equity capital on favorable terms, if at all. Even if we can obtain such additional equity financing if needed, there can be no assurance that we would be successful in raising such additional financing on favorable terms, if at all.

**Critical Accounting Policies and Estimates**

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

*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 debt 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 also have tenant leases and account for those leases in accordance with the lessor guidance under ASC Topic 842.

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.

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.

*Revenue Recognition*

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

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

*Use of Estimates* 

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

**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***

Revenues for the year ended December 31, 2022 were approximately $1.8 million, compared to approximately $1.6 million for the year ended December 31, 2021. The 17% increase primarily resulted from additional tenant leases commencing at SGR during the second and third quarters of 2022 and BNA during late 2022.

***Operating Expenses***

Operating expenses increased approximately $0.6 million, or 13%, from approximately $4.5 million for the year ended December 31, 2021 to approximately $5.0 million for the year ended December 31, 2022. This increase was primarily driven by an approximately $0.4 million increase in salaries, wages, and benefits associated with our campus personnel. The increase was reflective of a headcount increase at BNA associated with the opening of the BNA campus in the three months ended December 31, 2022, an increase at OPF as we prepare to commence operations in the three months ending March 31, 2023, and a headcount increase at SGR to accommodate increased tenant activity. Repair and maintenance expense associated with our hangars and related ground service equipment increased approximately $0.1 million, primarily driven by increased operations at our BNA and SGR campuses.

***Depreciation Expense***

Depreciation increased approximately $0.1 million, or 18%, for the year ended December 31, 2022, as compared to the year ended December 31, 2021. The increase reflects the opening of our BNA campus during the three months ended December 31, 2022 and the placement of additional ground support equipment into service throughout 2022.

***General and Administrative Expenses***

For the years ended December 31, 2022, and 2021, general and administrative expenses were approximately $14.7 million and approximately $8.7 million, respectively. The approximately $6.0 million increase was primarily driven by an approximately $2.5 million increase in salaries, wages, and benefits, which reflects an increase in full-time and contracted employees. The increase also reflects the implementation of stock and cash incentive compensation programs instituted to attract and retain employees. Other administrative expenses increased approximately $2.2 million driven primarily by insurance, franchise taxes, and computer and software expenses. Marketing and pursuit costs increased approximately $0.6 million in the year ended December 31, 2022, compared to the year ended December 31, 2021, reflecting our growth strategy in securing airport site acquisitions and potential tenants. Professional fees increased approximately $0.7 million due to an increase in legal, accounting, and consulting costs as compared to the prior year primarily as a result of becoming a public company.

***Other (Income) Expenses***

Other (income) expenses increased from approximately $1.4 million of other expense to approximately $5.2 million of other income for the year ended December 31, 2022 as compared to the year ended December 31, 2021. This increase was primarily due to an approximately $5.1 million mark-to-market gain of the outstanding warrants at December 31, 2022. These warrants were issued by YAC as part of its initial public offering. As a result, the warrants were not reflected in Sky's financial statements for the Year ended December 31, 2021.

**Liquidity and Capital Resources**

***Overview***

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

We believe that we have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional private activity bonds and other debt and the issuance of additional equity securities. However, as a new 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 PABs 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 December 31, 2022.

The following table summarizes our cash and cash equivalents, restricted cash, investments, and restricted investments as of December 31, 2022 and 2021 (in thousands):

***Common Stock Purchase Agreement***

On August 18, 2022, we entered into the Stock Purchase Agreement with B. Riley. Pursuant to the Stock Purchase Agreement, we have the right, in our sole discretion, to sell to B. Riley up to 10 million shares of our Class A Common Stock at 97% of the volume weighted average price of our Class A Common Stock calculated in accordance with the Purchase Agreement, over a period of 36 months subject to certain limitations and conditions contained in the Purchase Agreement. Sales and timing of any sales of Class A Common Stock are solely at our election, and we are under no obligation to sell any securities to B. Riley under the Purchase Agreement. As consideration for B. Riley's commitment to purchase shares of our Class A Common Stock, we have issued 25,000 shares of our Class A Common Stock to B. Riley as initial commitment shares and may issue up to an aggregate of 75,000 shares of our Class A Common Stock to B. Riley as additional commitment shares if certain conditions are met. As of December 31, 2022, we have sold no shares of our Class A Common Stock to B. Riley pursuant to the Stock Purchase Agreement. See "*Note 10* — *Equity and Redeemable Equity*" in the Notes to Consolidated Financial Statements for additional information regarding the Stock Purchase Agreement.

***Equity Financing***

On the Closing Date, we completed the Yellowstone Transaction, Yellowstone changed its name to Sky Harbour Group Corporation, and Sky restructured its capitalization, issuing its Sky Common Units to the Company. As a result of the Yellowstone Transaction, the Sky Common Units that Sky issued to BOC YAC in respect of its Series B Preferred Units were converted into 5,500,000 shares of the Company's Class A Common Stock and holders of Sky Common Units received one share of the Company's Class B Common Stock for each Common Unit. As consideration for the issuance of Sky Common Units to the Company, Yellowstone contributed approximately $48 million of net proceeds to us, consisting primarily of the BOC PIPE, and the amount held in the Yellowstone trust account, net of redemptions and transaction costs.

***Private Activity Bonds***

On September 14, 2021, SHC completed an issuance through the Public Finance Authority (Wisconsin) of $166.3 million of Series 2021 PABs. The Series 2021 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 PAB 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 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, 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 PABs.

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

***Debt Covenants***

The Series 2021 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 Series 2021 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 Series 2021 PABs.

Covenants in the Series 2021 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 Series 2021 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 December 31, 2022, we were in compliance with all debt covenants.

**Cash Flows**

***Historical Cash Flows***

The following table summarizes our sources and uses of cash for the Year ended December 31, 2022 and 2021 (in thousands):

---

| | | |
|:---|:---|:---|
|  | **Year ended** | **Year ended** |
|  | **December 31, 2022** | **December 31, 2021** |
| Cash and restricted cash at beginning of period | $203935 | $72 |
| Net cash used in operating activities | (27491) | (6615) |
| Cash used in investing activities | (187838) | (15994) |
| Net cash provided by financing activities | 52790 | 226472 |
| Cash and restricted cash at end of period | $41396 | $203935 |

---

*Operating Activities*

Cash provided by operating activities is significantly influenced by the amount of cash we invest in personnel and infrastructure to support the anticipated growth of our business. Included in net cash provided by operations are certain non-recurring legal, accounting, and consulting costs incurred for up to four quarters as a result of becoming a public company and a one-time outflow associated with the purchase of a leasehold interest at OPF. 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 $27.5 million for the year ended December 31, 2022, compared to $6.6 million for the same period in 2021. The $20.9 million increase in cash used in operating activities was primarily attributable to the $9.6 million of initial direct costs associated with the purchase of our former landlord's leasehold interest at OPF. The increase was also partially attributable to a $5.0 million increase in net loss, net of non-cash adjustments, and a $6.2 decrease in working capital. The increase in net loss and changes in working capital were primarily driven by general and administrative expenses incurred in the expansion of our business, including transaction-related expenses and other expenses related to corporate governance.

*Investing Activities*

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

Cash used in investing activities was $187.9 million for the year ended December 31, 2022, compared to $16.0 million for the same period in 2021. The increase of $171.9 million in cash used in investing activities was driven primarily by $193.8 million of purchases of held-to-maturity U.S. Treasury securities during the first and third quarters of 2022, the $30.0 million purchase of available-for-sale U.S. Treasury securities during the second quarter, and a $29.1 million increase in payments for costs of construction due to the Company's ongoing construction projects at BNA, OPF, APA, and DVT. These increases were offset by proceeds of $79.1 million received at maturity of certain of the Company's restricted investments.

*Financing Activities*

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

Net cash provided by financing activities was $52.8 million for the year ended December 31, 2022, compared to $226.4 million for the same period in 2021. The $173.6 million decrease in net cash provided by financing activities was primarily driven by $166.5 million of bond proceeds received during the third quarter of 2021 due to the issuance of the Series 2021 PABs, and $55.0 million of proceeds received from the issuance of the Sky Series B Preferred Units during the third quarter of 2021, and $30.0 million of proceeds from the issuance of Series A Preferred Units in the first quarter of 2021. These decreases were offset by $45.0 million of proceeds received from the issuance of the BOC PIPE and $15.7 million of gross proceeds from the Yellowstone trust account, both occurring in the first quarter of 2022.

| **ITEM 7A.** | **QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK** |

---

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices, and other market changes that affect market sensitive instruments. In pursuing our business and investment objectives, we expect that the primary market risk to which we will be exposed is interest rate risk. Following the issuance of the Series 2021 PABs, all of our indebtedness is now fixed rate debt. However, we may enter into variable rate debt agreements in the future, in which case we intend to hedge against rising benchmark interest rates by entering into hedging strategies with high quality counterparties. Our investments and restricted investments are invested in U.S. government treasury bills with maturity dates ranging between less than 180 days to 5 years. Due to the nature of these investments, as well as our intent and ability to hold these instruments to maturity, we believe there will be no associated material exposure to interest rate risk.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and Board of Directors<br> Sky Harbour Group Corporation:

*Opinion on the Financial Statements*

We have audited the accompanying consolidated balance sheets of Sky Harbour Group Corporation and Subsidiaries (the "Company") as of December 31, 2022 and 2021, and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows for each of the years then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2022 and 2021, and the consolidated results of their operations and their cash flows for each of the years then ended, in conformity with accounting principles generally accepted in the United States of America.

*Basis for Opinion*

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ EisnerAmper

We have served as the Company's auditor since 2020.

**SKY HARBOUR GROUP CORPORATION AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS**

**DECEMBER 31, 2022**

*(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."

On January 25, 2022 (the "Closing Date"), our predecessor, Yellowstone Acquisition Company ("Yellowstone"), a special purpose acquisition company incorporated in Delaware on August 25, 2020, consummated the business combination (the "Yellowstone Transaction") contemplated by the Equity Purchase Agreement, dated as of August 1, 2021 (the "Equity Purchase Agreement"), with Sky, a Delaware limited liability company.

As a result of the closing of the Yellowstone Transaction, and collectively with the other transaction described in the Equity Purchase Agreement, the Company was reorganized 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 "Common Units"). As of the Closing Date, SHG owned approximately 26.1% of the common units of Sky (the "Sky Common Units"), and the prior holders of Sky's Existing Common Units (the "LLC Interests") owned approximately 73.9% of the Sky Common Units and control the Company through their ownership of the Class B Common Stock, $0.0001 par value ("Class B Common Stock") of the Company. As of December 31, 2022, the Company and the LLC Interests owned approximately 26.1% and 73.9% of Sky Common Units, respectively. See Notes 2 and 3 for additional discussion related to the Yellowstone Transaction.

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

***Basis of Presentation***

The accompanying consolidated financial statements and the related notes (the "Financial Statements") have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission. These Financial Statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Certain historical amounts have been reclassified to conform to the current year's presentation, including salaries, wages, and benefits associated with operations personnel employed at the Company's hangar development sites. $193 of amounts previously classified within general and administrative expenses on the consolidated statement of operations for the year ended December 31, 2021, have been reclassified to operating expenses. This reclassification had no effect on total expenses, net loss, net loss per common share and had no impact on the Company's consolidated balance sheets, statement of stockholders' equity and statement of cash flows for the prior year period.

Notwithstanding the legal form of the Yellowstone Transaction pursuant to the terms therein, the Yellowstone Transaction was accounted for as a reverse recapitalization in accordance with GAAP (the "Reverse Recapitalization"). Under this method of accounting, Yellowstone was treated as the acquired company for financial reporting purposes, and Sky was treated as the accounting acquirer. In accordance with this accounting method, the Yellowstone Transaction was treated as the equivalent of Sky issuing stock for the net assets of Yellowstone, accompanied by a recapitalization.

Sky was deemed the accounting acquirer for purposes of the Yellowstone Transaction based on an evaluation of the following facts and circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The LLC Interests, through their ownership of the Class B Common Stock, hold a majority voting interest in the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The LLC Interests have the ability to nominate and elect the majority of the Company's Board of Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sky's senior management team comprises the senior management of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sky's assets were larger in relative size compared to Yellowstone's assets prior to the Yellowstone Transaction.

Thus, the financial statements included in this annual report for the year ended December 31, 2022 reflect (i) the historical operating results of Sky prior to the Yellowstone Transaction; (ii) the combined results of Sky and SHG from the date of the Yellowstone Transaction; and (iii) the net assets of SHG (formerly Yellowstone) were stated at historical cost, with no goodwill or other intangible assets recorded.

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

***Use of Estimates***

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

***Risks and Uncertainties***

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

The outbreak of COVID-19 caused severe disruptions in the global economy and adversely impacted businesses and financial markets. During 2020, the Company experienced delays in construction due to COVID-19 mandates such as physical distancing, supply chain issues, and subcontractor availability. In 2020, there was a significant slowdown in the aviation sector in general due to decreased travel which has since eased, particularly in private aviation. During 2021 and 2022, vaccinations for COVID-19 have become widely distributed among the general population which has resulted in loosened restrictions previously mandated. However, the potential emergence of vaccine-resistant variants of COVID-19 could result in restrictions being mandated again or affect the timing of loosened restrictions. The Company's management is not able, at this time, to determine what, if any, the ultimate impact COVID-19 will have on its future financial condition, results of operations and cash flows.

***Liquidity and Capital Resources***

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

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

***Significant Accounting Policies***

*Basis of Consolidation*

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

*Cash and Restricted Cash*

The Company's cash is held at a major commercial bank, which cash balance may at times exceed the Federal Deposit Insurance Corporation limit. To date, the Company has not experienced any losses on its cash deposits. The Company monitors the relative credit standing of financial institutions with whom the Company transacts and limits the amount of credit exposure with any one entity.

Pursuant to the Company's bond offering described in Note 8, various restricted trust bank accounts were established at a major financial institution. Such trust bank accounts are included in Restricted cash and Restricted investments on the consolidated balance sheet as of December 31, 2022 and December 31, 2021.

------

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

*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 as determined based upon quoted market prices. Such investments amounted to $24,895 as of December 31, 2022, of which $15,028 will mature in one year or less, and $9,867 will mature in one through five years. The gross and net amortized cost basis of such investments was $24,997 as of December 31, 2022.

Unrealized gains and losses are excluded from earnings and are reported as a component of comprehensive income (loss). The Company periodically evaluates whether declines in fair values of its available-for-sale securities below their book value are other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company's ability and intent to hold the available-for-sale security until a forecasted recovery occurs or its contractual maturity. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not it will be required to sell any available-for-sale securities before recovery of its amortized cost basis. Realized gains and losses and declines in fair value judged to be other than temporary, if any, on available-for-sale securities are included in other (income) expenses. The costs of investments sold is based on the specific-identification method. The Company recognized realized gains of $21 and $0 for the years ended December 31, 2022 and 2021, respectively. Interest on available-for-sale securities is included in other (income) expenses.

*Restricted Investments Held-to-Maturity*

Pursuant to provisions within the Master Indenture of the Series 2021 Bonds, as defined in Note 8, the Company invests the funds held in the restricted trust bank accounts in various U.S. Treasury securities. Therefore, such investments are reported as "Restricted investments" in the accompanying consolidated balance sheets.

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 held-to-maturity restricted investments are carried on the consolidated balance sheet at amortized cost. The carrying amount of such investments was $114,648 on December 31, 2022, of which $94,421 will mature in one year or less, and $20,227 will mature in one through five years.

*Cost of Construction* 

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

*Constructed assets, net*

Constructed assets on the consolidated balance sheets consists of developed aircraft hangar buildings and are carried at cost less accumulated depreciation. 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.

*Other long-lived assets*

Long-lived assets on the consolidated balance sheets consists principally of ground support equipment, software, and computer equipment. Long-lived assets are carried at cost less accumulated depreciation. Maintenance and repair expenses are charged to expense as incurred. Depreciation is recognized on a straight-line basis over 3 to 20 years, based on the estimated useful life of the assets.

*Impairment of long-lived assets*

The Company's assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment analyses are based on, in part, the Company's current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the property's carrying amount over its estimated fair value. Estimates of fair value are determined using discounted cash flow models, which consider, among other things, anticipated holding periods, current market conditions and utilize unobservable quantitative inputs, including appropriate capitalization and discount rates. If the estimates of the projected future cash flows, anticipated holding periods, or market conditions change, evaluation of impairment losses may be different and such differences could be material to the consolidated financial statements. The evaluation of anticipated cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and other factors that could differ materially from actual results.

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

*Leases*

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

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

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

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

*Warrants liability*

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

*Fair Value of Financial Instruments*

ASC Topic 820, Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities; Level 2 – quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of financial and non-financial assets and liabilities. Accordingly, fair value estimates may be different than the amounts that may ultimately be realized upon sale or disposition of these assets or settlement of these liabilities. See Note 14.

*Equity issuance costs*

The Company accounts for equity issuance costs as an asset within prepaid expenses and other assets on the consolidated balance sheets until the related equity financing is obtained, and then reclassifies such costs as a reduction in equity. As of December 31, 2021, the Company had $2,696 of equity issuance costs included within prepaid and other assets which were subsequently reclassified as part of accounting for the Yellowstone Transaction. As of December 31, 2022, there were $217 of equity issuance costs included within prepaid expenses and other assets.

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

*Revenue recognition* 

The Company leases the hangar facilities that it constructs to third parties. The lease agreements are either on a month-to-month basis or have a defined term and may have options to extend the term. Some of the leases contain options to terminate the lease by either party with given notice. There are no options given to the lessee to purchase the underlying assets. Rental revenue is recognized in accordance with ASC Topic 842, Leases (see Note 7) and includes (i) fixed payments of cash rents, which represents revenue each tenant pays in accordance with the terms of its respective lease and is recognized on a straight-line basis over the term of the lease and (ii) variable payments of tenant reimbursements, which are recoveries of all or a portion of the common area maintenance and operating expenses of the property and are recognized in the same period as the expenses are incurred. As of December 31, 2022 and December 31, 2021, the deferred rent receivable included in prepaid expenses and other assets was $83 and $103, respectively.

The Company evaluates the collectability of tenant receivables for payments required under the lease agreements. If the Company determines that collectability is not probable, the Company recognizes any difference between revenue amounts recognized to date under ASC 842 and payments that have been collected from the lessee, including security deposit amounts held, as a current period adjustment to rental revenue. There were no material adjustments to rental revenue for uncollectible tenant rental payments in either of the year ended December 31, 2022 or 2021.

For the year ended December 31, 2022 and 2021, the Company derived 78% and 89% of its revenue from two tenants, respectively. Such tenants have ongoing leases with the Company which expire in December 2023 and November 2025, respectively.

*Operating Expenses*

For the years ended December 31, 2022 and 2021, operating expenses within the consolidated statements of operations includes operating lease expense of $3,735 and $3,747, respectively. General and administrative expenses on the consolidated statements of operations also includes $81 and $51 of operating lease expense for the year ended December 31, 2022 and 2021, respectively.

*Advertising Costs*

The Company expenses the cost of advertising and marketing as incurred. Advertising and marketing costs recognized as general and administrative expenses totaled $340 for the year ended December 31, 2022, and $292 for the year ended December 31, 2021.

*Income Taxes*

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

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

Amounts payable under the Tax Receivable Agreement, as defined in Note 3, are accrued by a charge to income when it is probable that a liability has been incurred and the amount is estimable.

**3.** **Yellowstone Transaction** 

As contemplated by the Equity Purchase Agreement, on the Closing Date, the following occurred:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Yellowstone changed its name to Sky Harbour Group Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All outstanding shares of stock held by BOC Yellowstone LLC (the "Sponsor") were converted into shares of Class A Common Stock, $0.0001 par value ("Class A Common Stock") of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sky restructured its capitalization and issued to the Company 14,937,581 Sky Common Units, which was equal to the number of outstanding shares of Class A Common Stock immediately after giving effect to the Equity Purchase Agreement. The number of outstanding shares after the Equity Purchase Agreement reflected the redemption of Class A Common Stock (by former holders of the special purpose acquisition company shares that elected to redeem such shares) and the Class A Common Stock issued as a result of the BOC PIPE investment (the "BOC PIPE"), the reclassification of the existing Sky Common Units (other than the Sky Incentive Units, as defined in Note 11), existing Sky Series A preferred units (the "Series A Preferred Units") and Series B preferred units (the "Series B Preferred Units") into Sky Common Units.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain adjustments were affected to the number of Sky Incentive Units to reflect the new capital structure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• SHG was appointed as the managing member of Sky under the Third Amended and Restated Operating Agreement (the "A&R Operating Agreement").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Sky Common Units issued to the Sponsor in respect of Sky's Series B Preferred Units were converted into 5,500,000 shares of Class A Common Stock of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The LLC Interests received one share of Class B Common Stock for each Sky Common Unit that they held, and as consideration for the issuance of 14,937,581 Sky Common Units by Sky to the Company, Yellowstone contributed to Sky the net amount held in the Yellowstone trust account after deducting the amount required to fund the redemption of the Class A Common Stock held by eligible stockholders who properly elected to have their shares redeemed as of the Closing Date and the amount of various transaction costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Yellowstone Warrants that were issued and outstanding immediately prior to the Closing Date became SHG Warrants.

The following table reconciles the elements of the Yellowstone Transaction to the consolidated statements of changes in equity for the year ended December 31, 2022:

---

| | |
|:---|:---|
|  | **Yellowstone Transaction** |
| Cash - Yellowstone trust and cash, net of redemptions | $15691 |
| Cash - BOC PIPE investment | 45000 |
| Less: transaction costs and advisory fees | (12731) |
| Net proceeds from the Yellowstone Transaction | $47960 |
| Conversion of Sky Series B preferred units to Class A Common Stock | 54029 |
| Less: Initial fair value of Warrants liability assumed on 1/25/2022 | (7986) |
| **Net adjustment to total equity from the Yellowstone Transaction** | $**94003** |

---

The following table reconciles the number of shares of SHG Common Stock immediately following the consummation of the Yellowstone Transaction:

---

| | |
|:---|:---|
|  | **Number of shares** |
| Yellowstone Common stock, outstanding prior to Yellowstone Transaction | 13598898 |
| Less: redemption of Yellowstone Common Stock | (12061041) |

*Tax Receivable Agreement*

On the Closing Date, in connection with the completion of the Yellowstone Transaction and as contemplated by the Equity Purchase Agreement, the Company, Sky, the LLC Interests, and the TRA Holder Representative, entered into a tax receivable agreement (the "Tax Receivable Agreement"). Pursuant to the Tax Receivable Agreement, the Company will generally be required to pay the LLC Interests 85% of the amount of savings, if any, in U.S. federal, state, local, and foreign taxes that are based on, or measured with respect to, net income or profits, and any interest related thereto that the Company realizes, or is deemed to realize, as a result of certain tax attributes, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• existing tax basis in certain assets of Sky and certain of its direct or indirect subsidiaries, including assets that will eventually be subject to depreciation or amortization, once placed in service, attributable to Sky Common Units acquired by the Company from a TRA Holder, as determined at the time of the relevant acquisition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax basis adjustments resulting from taxable exchanges of Sky Common Units (including any such adjustments resulting from certain payments made by the Company under the Tax Receivable Agreement) acquired by the Company from a TRA Holder pursuant to the terms of the A&R Operating Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax deductions in respect of portions of certain payments made under the Tax Receivable Agreement (each of the foregoing, collectively, the "Tax Attributes").

**6.** **Supplemental Balance Sheet and Cash Flow Information** 

*Prepaid expenses and other assets*

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

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

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

**7.** **Leases** 

*Lessee*

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

The Company's lease population does not include any residual value guarantees, and therefore none were considered in the calculation of the ROU and operating lease liability balances. The Company has operating leases that contain variable payments, most commonly in the form of common area maintenance and operating expense charges, which are based on actual costs incurred. These variable payments were excluded from the calculation of the ROU asset and operating lease liability balances since they are not fixed or in-substance fixed payments. These variable payments were not material in amount for both of the years ended December 31, 2022 and 2021. 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 17.

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

The Company's ground lease at OPF was entered into in May 2019 through its wholly owned subsidiary, Sky Harbour Opa Locka Airport LLC ("SHOLA"), with AA Acquisitions LLC ("AA"). AA is the master ground lessee of Miami Dade County ("MDC"), the ultimate landowner. On April 29, 2022, the Company, through a wholly-owned subsidiary outside the Obligated Group (as defined in Note 8), purchased AA's underlying interest in the ground lease for approximately $8.5 million and now leases the OPF property directly from MDC (the "OPF Lease Transaction"). The OPF Lease Transaction also required the Company to pay approximately $1.0 million in assignment fees to MDC, which, along with the $8.5 million purchase price, were recognized as initial direct costs and presented as a component of right-of-use assets. Following the OPF Lease Transaction, SHOLA continues to be obligated under the existing sublease but to an affiliate within the Company. The OPF Lease Transaction extends the term of the lease at OPF for the Company to approximately 57 years. The Company has accounted for the OPF Lease Transaction as a lease modification requiring remeasurement and remeasured the right-of-use asset and operating lease liability utilizing the Company's incremental borrowing rate as of the date of remeasurement. As a result of the remeasurement, non-cash subtractions to the right-of-use asset and operating lease liability of $12,289 were recorded during April 2022.

On January 1, 2021, the Company commenced an operating lease for a ground lease located at APA ("APA Lease"), with an initial lease term of 41 years (or up to 76 years including extension options). The APA Lease contains an option to lease an additional parcel of land (Phase II) that must be exercised, at the Company's option, within three-years of the lease's commencement date.

On May 4, 2021, the Company commenced an operating lease for a ground lease located at DVT ("DVT Lease"), with a lease term of 40 years. The DVT Lease contains an option to lease an additional parcel of land (Phase II) that must be exercised, at the Company's option, within four-years of the lease's commencement date.

On June 28, 2022, the Company commenced an operating lease for a ground lease located at ADS ("ADS Lease"). The ADS Lease term is 40 years from the completion of construction with no additional extension options, which is the maximum allowable term permitted by the Town of Addison. The ADS Lease was amended on January 19, 2023, see Note 18, *Subsequent Events*.

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

*Lessor*

The Company leases the hangar facilities that it constructs to third-party tenants. These leases have been classified as operating leases. The Company does not have any leases classified as sales-type or direct financing leases. Lease agreements with tenants are either on a month-to-month basis or have a defined term with an option to extend the term. The defined term leases vary in length at inception from one to five years with options to renew for additional term(s) given to the lessee. One of the agreements contains an option by either party to terminate with appropriate notice, as defined. There are no options given to the lessee to purchase the underlying assets. The Company determines whether a contract contains a lease at the inception of the contract. 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 residual value guarantees. The Company mitigates risk related to the residual value of the assets by negotiating with current tenants and attempting to secure future tenants through letters of intent prior to the current lease term's termination and/or the substantial completion of the promised hangar facilities that are presently under construction.

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

Tenant leases to which the Company is the lessor require the following non-cancelable future minimum lease payments from tenants as of December 31, 2022:

---

| | |
|:---|:---|
| **Year Ending December 31,** | **Operating Leases** |
| 2023 | $2516 |
| 2024 | 1200 |

| 2026 |  |
| 2027 |  |

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

*Bonds payable*

On May 20, 2021, Sky formed a new wholly-owned subsidiary, Sky Harbour Capital LLC, as a parent corporation to its wholly-owned subsidiaries that operate each of the aircraft hangar development sites under its ground leases. Sky Harbour Capital LLC 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 sub-leasehold 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 Sky Harbour Capital LLC have each pledged as collateral its respective ownership interest in any of the Borrowers.

The bond trustee established various restricted bank accounts which were initially funded with the bond proceeds and cash on hand. The bond trustee will continue to control the Borrowers' cash receipts and disbursements under a Trust Agreement. Such restricted funds are available to fund the construction expenditures of the two phases of OPF, BNA, DVT, and APA, and SGR Phase II, and, with certain approvals and supplemental reports, up to $50 million at other airport sites, in addition to certain operating expenses such as ground lease expense. These accounts also include funds to pay debt service through the end of construction at each site and various reserve funds such as a ramp-up reserve, debt service reserve, and a maintenance reserve fund. Such trust bank accounts total approximately $152.5 million, of which $37.9 million and $114.6 million and are included in Restricted cash and Restricted investments, respectively, on the consolidated balance sheet as of December 31, 2022.

The Borrowers have agreed to use all commercially reasonable efforts to jointly maintain a Debt Service Coverage Ratio (as defined in the agreement) of 1.25 for each applicable test period; provided, however, that the failure to maintain this ratio will not be considered an event of default so long as the Obligated Group takes all commercially reasonable action for correcting such deficiency. The measurement of the Debt Service Coverage Ratio will commence with the period ending December 31, 2024. If the Debt Service Coverage Ratio as of the end of any fiscal quarter is less than 1.0, the parent companies of the Borrowers will make contributions to the borrowers or otherwise cause the Debt Service Coverage Ratio to be at least 1.0 within 10 business days of the test date. If the Debt Service Coverage Ratio as of the end of any fiscal quarter is less than 1.25, Sky Harbour Capital LLC must deliver to the trustees, within 120 days, an independent consultant's report and a specific plan designed to achieve a Debt Service Coverage Ratio of 1.25 in the following fiscal year.

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.

The bonds maturing on July 1, 2036 are subject to optional early redemption, at the option of Sky Harbour Capital LLC, on or after July 1, 2028, in whole or in part, at a redemption price equal to the principal amount plus interest accrued to the redemption date. The bonds maturing on July 1, 2041 and July 1, 2054 are subject to optional early redemption, at the option of Sky Harbour Capital LLC, on or after July 1, 2031, in whole or in part, at a redemption price equal to the principal amount plus interest accrued to the redemption date. An extraordinary optional redemption is permitted in the event of damage or destruction of any of the underlying assets.

The Series 2021 Bonds are mandatorily redeemable upon the occurrence of certain events. Upon the sale of an asset by any Borrower, the applicable portion of the Series 2021 Bonds is subject to special mandatory redemption at prices specified in the agreement. Upon the occurrence of a determination of taxability in which the interest income of any of the bonds does not qualify as being excludable from the gross income of the holder (with limited exclusions), the Series 2021 Bonds are subject to mandatory redemption within 60 days, at a redemption price equal to the principal amount plus accrued interest. Upon the termination of any ground lease of a Borrower, and unless certain other certifications can be made, the Series 2021 Bonds are subject to redemption in an amount and at a redemption price as specified in the agreement. In lieu of redemption, the Bonds may be purchased by any of the Borrowers or by any party designated by Sky Harbour Capital LLC.

| **Total Bonds payable, net** | $**162210** | $**160679** |

---

In connection with the issuance of the Bonds Payable, the Company originally recognized debt issuance costs totaling $6 million which are being amortized into interest using the effective interest method over the life of the bonds. Interest that is incurred at the stated interest rate of the bonds, as well as the amortization of bond premium and amortization of debt issuance costs are capitalized and added to the cost of construction on the consolidated balance sheet. During the year ended December 31, 2022, the Company received a refund of approximately $1.2 million of debt issuance costs associated with the issuance of the Bonds Payable, and recognized the refund as a reduction of debt issuance costs.

*Loans payable*

In connection with two of its development projects, Sky had two secured construction loans that were outstanding through the loans' respective payoff dates of August 11, 2021 and September 3, 2021.

Sky closed on a construction loan on August 28, 2019 for up to $16.7 million for the development of the SGR project (the "SGR Loan"). The loan bore interest at LIBOR (subject to a minimum of 2.2%) plus 6%, plus pay-in-kind ("PIK") interest of 2% which was added to the principal amount. The SGR Loan was repaid on September 3, 2021, including all accrued and PIK interest.

On January 23, 2020, Sky closed on a construction loan for up to $46.0 million for the development of the OPF project (the "OPF Loan"). The loan bore interest at LIBOR (subject to a minimum of 1.669%) plus 6%, plus PIK interest of 2% which was added to the principal amount. An amendment to the loan on March 12, 2021 increased the interest rate to LIBOR (subject to a minimum of 1.669%) plus 8%, plus PIK interest of 2% that was added to the principal amount. The OPF Loan was repaid on August 11, 2021, including all accrued and PIK interest.

**9.** **Warrants** 

As part of Yellowstone's initial public offering, Yellowstone issued to third-party investors 6,799,439 warrants which entitled the holder to purchase one share of Class A Common Stock at an exercise price of $11.50 per share (the "Public Warrants"). In addition, 7,719,779 private placement warrants were sold to the Sponsor (the "Private Placement Warrants", and together with the Public Warrants, the "Warrants"). Each Private Warrant allows the Sponsor to purchase one share of Class A Common Stock at an exercise price of $11.50 per share. Following the Yellowstone Transaction, the Warrants remain outstanding under the same terms and conditions to purchase shares of the Company's Class A Common Stock. As of December 31, 2022, 6,799,189 and 7,719,779 Public and Private Warrants remain outstanding, respectively.

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

The closing price of the Public Warrants was $0.20 and $0.55 per warrant on December 31, 2022 and the Closing Date, respectively. The aggregate fair value of the Warrants was approximately $2.9 million and $8.0 million as of December 31, 2022 and the Closing Date, respectively. During the year ended December 31, 2022, the Company recorded an unrealized gain of approximately $5.1 million, reflecting the change in fair value of the Warrants from the Closing Date through December 31, 2022.

**10.** **Equity and Redeemable Equity** 

*Prior to the Yellowstone Transaction*

Sky and its members initially entered into a Limited Liability Company Agreement on February 12, 2018. This LLC agreement was subsequently amended and restated on March 12, 2021 (the "First A&R Operating Agreement"), which was again amended and restated on September 14, 2021 (the "Second A&R Operating Agreement"). On January 25, 2022, in connection with the Yellowstone Transaction, Sky, its members, and SHG entered into the A&R Operating Agreement.

On March 12, 2021, there was a change in the ownership of Sky such that the former majority member no longer held an interest in Sky pursuant to a redemption agreement (the "Redemption Agreement"), and additional members invested in Sky pursuant to a unit purchase agreement (the "Unit Purchase Agreement"). Pursuant to the Unit Purchase Agreement, Sky's former minority member (the "Founder") received founder units of Sky (the "Founder Units") and the new investors purchased a total of $31.3 million in Series A Preferred Units of Sky. Pursuant to a convertible note and exchange agreement dated March 12, 2021 (the "Convertible Note and Exchange Agreement"), a portion of the proceeds from the issuance of the Series A Preferred Units were used to fully satisfy outstanding note payable between Sky and a related party as described in Note 14*.*

On August 1, 2021, Sky entered into the Equity Purchase Agreement with Yellowstone. In conjunction with the Equity Purchase Agreement, Boston Omaha Corporation agreed to invest $55.0 million of equity in the form of Redeemable Series B Preferred Units through its affiliate BOC YAC Funding LLC ("BOC YAC"). On September 14, 2021, Sky issued 8,049 Series B Preferred Units to BOC YAC in exchange for the $55.0 million. The Series B Preferred Units contained redemption rights for both Sky and for the holders of the Series B Preferred Units under certain circumstances. Because the Series B Preferred Units were redeemable in cash, they were classified as Temporary Equity, between the Liabilities and Equity sections of the consolidated balance sheet as of December 31, 2021. They were carried at their net issuance price and not reflected at redemption value in the consolidated balance sheet because no Series B Preferred Units were redeemed between December 31, 2021 and January 25, 2022, the date such Units were automatically converted to the Company's Class A Common Stock equal to the original $55.0 million investment at the conversion price of $10 per share.

*Recapitalization*

As of December 31, 2021, there were 31,250 Series A Preferred Units, 8,049 Series B Preferred Units, and 27,035 Founder Units authorized, issued and outstanding. As a result of the Reverse Recapitalization on the Closing Date, the Series A Preferred Units and Founder Units converted into 42,192,250 Sky Common Units and the LLC Interests received 42,192,250 shares of SHG's Class B Common Stock. The Series B Preferred Units converted to 5,500,000 shares of SHG's Class A Common Stock, and Sky issued 14,937,581 Sky Common Units to SHG, which was equivalent to the total number of shares of the SHG's Class A Common Stock outstanding on the Closing Date.

As of December 31, 2022, there were 14,962,831 and 42,192,250 shares of Class A Common Stock and Class B Common Stock outstanding, respectively. Holders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters submitted to the stockholders for their vote or approval, except as required by applicable law. Holders of Class A Common Stock and Class B Common Stock are entitled to one vote per share on all matters submitted to the stockholders for their vote or approval.

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

On January 17, 2022, the Company entered into a forward purchase agreement (the "Forward Purchase Agreement") with ACM ARRT VII E LLC (the "Counterparty"), pursuant to which the Counterparty had the right, but not the obligation, to purchase up to 7,000,000 shares of Class A Common Stock from shareholders who had redeemed shares, or indicated an interest in redeeming shares, prior to the closing of the Yellowstone Transaction. The Counterparty purchased 664,909 such shares and, immediately following the Closing Date, pursuant to the agreement, the Company paid to the Counterparty a forward price of approximately $6.7 million. The Counterparty also had the right to sell such shares to others during an 18-month term, terminating the Company's forward purchase obligations, and repaying to the Company a portion of the forward price, in amounts corresponding to the number of shares sold. On March 7, 2022, the Counterparty notified the Company that it had sold the 664,909 shares covered by the agreement. As a result, a total of approximately $6.7 million was remitted to the Company by the Counterparty.

*Common Stock Purchase Agreement*

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

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

In consideration for entering into the Stock Purchase Agreement and concurrently with the execution of the Stock Purchase Agreement, the Company issued to B. Riley 25,000 shares of Class A Common Stock as initial commitment shares and will issue up to an aggregate of 75,000 shares of its Class A Common Stock as additional commitment shares if certain conditions and milestones are met. The Company recognized expense associated with the issuance of such commitment shares of $112 during the year ended December 31, 2022 based on the fair value of the Company's Class A Common Stock on the date of issuance.

*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 December 31, 2022 and represents the Sky Common Units held by holders other than SHG. The holders of LLC Interests may, following the expiration of an applicable lock-up period, exchange Sky Common Units along with an equal number of Class B Common Shares, for Class A Common Shares on the Company. The LLC Interests do not have the option to redeem their Sky Common Units for cash or a variable number of Class A Common Shares, nor does SHG have the option to settle a redemption in such a manner. As of December 31, 2022, the LLC interests owned approximately 73.9% of the Sky Common Units outstanding.

**11.** **Equity Compensation** 

*Restricted Stock Units (*"*RSUs*"*)*

On January 25, 2022, the Company's 2022 Incentive Award Plan (the "2022 Incentive Award Plan") became effective following approval by the Company's shareholders. The 2022 Incentive Award Plan provides for grants of stock-based compensation awards, including without limitation, non-qualified stock options, incentive stock options, stock appreciation rights, or SARs, restricted stock awards, restricted stock unit awards, incentive unit awards other stock or cash based awards and dividend equivalent awards. Employees, officers, and consultants of the Company or any parent or affiliate, including Sky, or any non-employee director of the Company's Board of Directors are eligible to receive awards under the 2022 Incentive Award Plan. An aggregate of 5.2 million shares of Class A Common Stock are issuable pursuant to the 2022 Incentive Award Plan.

During the year ended December 31, 2022, the Company granted 735,000 time-based RSUs to certain employees under the Company's 2022 Incentive Award Plan at a weighted average grant date fair value of $7.64. The RSUs will vest ratably over a four-year period beginning on the first anniversary of the grant date and ending on fourth anniversary. All RSUs were valued at their fair market value, which is the closing price of the Company's stock on the date of the grant. During the year ended December 31, 2022, the Company recognized stock compensation expense of $764. As of December 31, 2022, there are 645,000 non-vested RSUs outstanding with a weighted average grant date fair value of $7.63. No RSUs have vested during the year ended December 31, 2022 and 90,000 RSUs have been forfeited. The unrecognized compensation costs associated with all unvested RSUs at December 31, 2022 was $4,159 that is expected to be recognized over a weighted-average future period of 3.4 years.

*Sky Incentive Units*

In May 2021, Sky granted 3,951 Sky Incentive Units to certain employees. In connection with the Yellowstone Transaction and the execution of the Third A&R Operating Agreement, the number of existing Sky Incentive Units outstanding was adjusted based on a defined unit conversion ratio to reflect the new capital structure (see Note 10) and remain Sky Incentive Units, resulting in 2,807,750 outstanding Sky Incentive Units. These Incentive Units may be exchanged for Sky Common Units at the holder's discretion upon vesting. There were no changes to the terms or conditions of the Sky Incentive Units effected by the Yellowstone Transaction. The Sky Incentive Units are classified as equity instruments.

The Sky Incentive Units were valued as of the date of grant using the Option-Pricing Method described in the AICPA Accounting and Valuation Guide entitled *Valuation of Privately Held Company Equity Securities Issued as Compensation.* The Option-Pricing Method treated profit units (such as Sky Incentive Units) and the capital units outstanding at the time of the valuation (Sky's Series A Preferred Units, Series B Preferred Units, and the Founder Units) as call options on the total equity value of Sky, with exercise (or strike) prices based on the incremental equity required to repay liquidation preferences for the various holders of Sky interests. The values of the options associated with each strike price were calculated using the Black-Scholes option pricing model based on the grant date. The Sky Incentive Units were classified as Level 3 in the fair value hierarchy. The key inputs and assumptions used in the valuation of the Sky's Incentive Units were:

---

| | |
|:---|:---|
| Fair value of total equity | $62287970.0 |
| Term (in years) | 5.0 |
| Risk-free interest rate | 0.84% |
| Volatility | 57.0% |

---

Below is a summary of activity related to the Sky Incentive Units for the Year ended December 31, 2022:

---

| | | |
|:---|:---|:---|
|  | **Sky Incentive Units** | **Weighted-average grant date fair value** |
| Sky units outstanding as of December 31, 2021 (as previously presented) | 3951 | $318.44 |
| Sky units outstanding as of December 31, 2021 (recast for recapitalization) | 2807750 | $0.45 |
| Granted |  | $- |
| Forfeitures |  | $- |
| Sky units outstanding as of December 31, 2022 | 2807750 | $0.45 |
| Vested Units outstanding as of December 31, 2022 | 1244570 | $0.45 |
| Non-vested Units outstanding as of December 31, 2022 | 1563180 | $0.45 |

---

The Company recognizes equity-based compensation expense on a straight-line basis over the requisite service period and has elected to account for forfeitures of Sky Incentive Units if and when they occur. The Company recorded equity-based compensation expense relating to Sky Incentive Units of $341 for the year ended December 31, 2022, which is recorded within General and Administrative Expenses within the statement of operations, and as a component of the non-controlling interest in the consolidated statement of changes in stockholders' equity. The Company recorded equity-based compensation expense relating to Sky Incentive Units of $217 for the year ended December 31, 2021. As of December 31, 2022, there was $700 of total unrecognized compensation expense that is expected to be recognized over a weighted-average future period of 2.3 years.

**12.** **Income Taxes** 

*Effective Tax Rate Reconciliation*

We are subject to taxation in all jurisdictions in which we operate that impose an income tax on our business activities. The components of the income tax expense for the years ended December 31, and the tax effects of temporary differences that give rise to deferred taxes at December 31, are as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2022** | **2021** |
| **Income tax benefit:** |  |  |
| Deferred federal income tax benefit | (1558) |  |
| Deferred state income tax benefit | (285) |  |
| Total income tax benefit before valuation allowance | (1843) |  |
| Valuation allowance | 1843 |  |
| Total income tax benefit | $- | $- |

---

A reconciliation of the statutory federal income tax expense to the income tax expense (benefit) from continuing operations provided at December 31, 2022 and December 31, 2021 is as follows:

---

| | | |
|:---|:---|:---|
|  | **For the Year Ended December 31,** | **For the Year Ended December 31,** |
|  | **2022** | **2021** |
| Income tax benefit at the federal statutory rate of 21% | $(554) | $- |
| State income tax benefit, net of federal benefit | (225) |  |
| Unrealized gain on warrants | (1067) |  |
| Other, net | 3 |  |
| Change in valuation allowance | 1843 |  |
| Total income tax benefit | $- | $- |

---

The Company recorded income tax expense of $0 and the effective tax rate was 0.0% for the years ended December 31, 2022 and 2021. The effective income tax rate for the year ended December 31, 2022 differs from the federal statutory rate of 21% primarily due to a full valuation allowance against net deferred tax assets as it is more likely than not that the deferred tax assets will not be realized. For the year ended December 31, 2021, Sky was not subject to U.S. Federal and certain state income taxes at the entity level prior to the Yellowstone Transaction (See Note 2).

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

Components of the Company's deferred tax assets at December 31, 2022 and December 31, 2021 are as follows:

---

| | | |
|:---|:---|:---|
|  | **For the Year Ended December 31,** | **For the Year Ended December 31,** |
|  | **2022** | **2021** |
| Deferred tax assets: |  |  |
| &nbsp;&nbsp;&nbsp; Amortization | $470 | $- |
| &nbsp;&nbsp;&nbsp; Difference between book and tax capital accounts | $90 |  |
| Stock-based compensation | 179 |  |
| Net operating loss carryforwards | 1923 |  |
| Valuation allowance | (2661) |  |
| Total deferred tax assets | $1 | $- |
| Deferred tax liabilities: |  |  |
| &nbsp;&nbsp;&nbsp; Unrealized Gain/Loss on investments | $(1) | $- |
| Total deferred tax liabilities | $(1) | $- |
| Total | $- | $- |

---

The realization of deferred tax assets, including net operating loss carryforwards ("NOLs"), is dependent on the generation of future taxable income sufficient to realize the tax deductions, carryforwards, and credits. Valuation allowances on deferred tax assets are recognized if it is determined that it is more likely than not that the asset will not be realized. For the year ended December 31, 2022, we recorded a full valuation allowance due to historical losses before income taxes which reduced management's ability to rely on future expectations of income.

As of December 31, 2022, we have available federal tax operating loss carryforwards of approximately $8.2 million, including approximately $1.7 million generated by our legal predecessor prior to the Yellowstone Transaction. All federal tax operating loss carryforwards arose in tax years subsequent to 2017. Tax operating loss carryovers arising in years after 2017 may be carried forward indefinitely but are only available to offset 80% of future taxable income. We have available state tax operating loss carryforwards of approximately $8.2 million, which are available to reduce future state taxable income and would begin to expire in tax year 2040 in various amounts. Utilization of our net operating loss carryforwards may be subject to substantial annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code, as amended, and similar state provisions.

*Uncertain Tax Positions*

We believe that there are no tax positions taken or expected to be taken that would significantly increase or decrease unrecognized tax benefits within 12 months of the reporting date.

The federal and state statutes of limitation for assessment of tax liability generally lapse within three years after the date the tax returns are filed. However, income tax attributes that are carried forward, such as net operating loss carryforwards, may be challenged and adjusted by taxing authorities at any time prior to the expiration of the statute of limitations for the tax year in which they are utilized. As of December 31, 2022, we do not have any open exams; however, all tax years, including those of our legal predecessor, are subject to examination by the Internal Revenue Service.

**13.** **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 method.

Shares of the Company's Class B Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B Common Stock under the two-class method has not been presented. For the year ended December 31, 2021, the membership structure of Sky solely included holders of Sky Common Units that received an equivalent number of Class B Common Stock following the Yellowstone Transaction, and there were no holders that received Class A Common Stock. As the shares of Class B Common Stock are not participating securities, presentation of net loss per share for the year ended December 31, 2021 would not be meaningful to the users of these consolidated financial statements, and such information has not been presented.

| Basic and diluted weighted average shares outstanding | 13965 |
| Loss per share of Class A Common Stock – Basic and diluted | $(0.23) |

---

Potentially dilutive shares associated with the outstanding Warrants were antidilutive for the year ended December 31, 2022 due to the Company's net loss position. Thus, 14,518,968 shares issuable upon the exercise of the Warrants were excluded from the calculation of diluted weighted average shares outstanding and diluted loss per share for the year ended December 31, 2022. 645,000 potentially dilutive shares associated with the Company's restricted stock units were antidilutive for the year ended December 31, 2022 and excluded from the calculation due to the Company's net loss position.

The Company's Class B Common Stock and the Sky Incentive Units are both potentially dilutive as the holders of such securities may ultimately exchange such securities for the Company's Class A Common Stock. 42,192,250 potentially dilutive shares associated with the Company's Class B Common Stock and 2,807,750 potentially dilutive shares associated with the Sky Incentive Units were antidilutive for the year ended December 31, 2022 and excluded from the calculation due to the Company's net loss position.

The fair value of the Company's investments and restricted investments is estimated utilizing Level 1 inputs including prices for U.S. Treasury securities with comparable maturities on active markets. The fair value of the Company's bonds is estimated utilizing Level 2 inputs including prices for the bonds on inactive markets. See Note 9 for discussion regarding the estimation of the fair value of the warrants. The carrying values of all other financial instruments on the consolidated balance sheets, approximate their fair values due to the short-term nature of these instruments.

**15.** **Related Party Transactions** 

*Loans payable to Related parties*

Sky previously was party to a loan from a company owned by its former majority member. The loan payable bore interest at an annual rate of 5.50% and all interest was PIK interest. On March 12, 2021, pursuant to a Redemption Agreement between Sky and the former majority member, the loan was cancelled and all of the membership interests held by the former majority member were redeemed in exchange for a sum of $5.1 million, plus a Reimbursement and Indemnity Agreement from Sky and the Founder and CEO. Sky recorded a gain on extinguishment of this related party loan payable of $5.6 million, net of related expenses of $0.15 million and net of redemption of membership interests. The gain was recognized as a deemed contribution to stockholders' equity on the consolidated balance sheet. Interest incurred on the loan payable to for the year ended December 31, 2021 totaled $115.

Beginning in November 2020, Sky entered into a note payable with a related party, SH Investment Fund I LLC, a company controlled by the Founder and CEO. The note payable bore interest at 8% per annum and had a maturity date of November 24, 2021. Amounts payable under the note were drawn by requesting "advances" from the lender, up to $1,000,000, and could be used by Sky only for certain types of expenditures that were approved in advance by the lender. On March 12, 2021, Sky issued 1,250 Series A Preferred Units in full satisfaction of the note payable by Sky to SH Investment Fund I LLC. The fair value of the 1,250 units was $1.25 million and exceeded the carrying value of the $1.0 million note payable at the time of extinguishment; thereby resulting in a loss on extinguishment of related party debt of $0.25 million which was recorded as a charge in the consolidated statement of operations.

*Services*

For the year ended December 31, 2022, the Company paid $108 for consulting services to a company that employed the chief financial officer until prior to July 1, 2021. The Company paid $142 during the year ended December 31, 2021 to the same company.

On September 20, 2021, the Company entered into a non-exclusive agreement with Echo Echo, LLC, a related party to the Founder and CEO, for the use of a Beechcraft Baron G58 aircraft. The effective date of the agreement was September 8, 2021 and the agreement automatically renews annually. The agreement can be terminated without penalty if either party provides 35 days written notice, or if the aircraft is sold or otherwise disposed of. The Company is charged per flight hour of use along with all direct operating costs. Additionally, the Company will also incur the pro rata share of maintenance, overhead and insurance costs of the aircraft. For the year ended December 31, 2022, the Company recognized $194 of expense, within general and administrative expense under the terms of this agreement. The related liability of $48 is included in accounts payable, accrued expenses and other liabilities on the consolidated balance sheet as of December 31, 2022.

**16.** **Commitments and Contingencies** 

In addition to the lease payment commitments discussed in Note 7, 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.

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

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

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

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

The Company has contracts for construction of the OPF Phase I, APA Phase I, and DVT Phase I projects. The Company may terminate any of the contracts or suspend construction without cause; however, the Company would be subject to paying a penalty under the OPF Phase I construction contract of 50% of the unrealized fee which remains to be earned as of the termination date. There are no termination penalties under the APA Phase I or DVT Phase I construction contracts.

During the year ended December 31, 2022, the Company reported reclassifications of $21 of unrealized gains on available-for-sale securities to net income as a component of other (income) expense.

**18.** **Subsequent Events** 

*ADS Lease Amendment*

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

*Series 2021 PABs Scope Modification*

On March 22, 2023, SHC elected to modify the scope of its Series 2021 PABs pursuant to the terms of the Master Indenture, in order to reallocate a portion of the proceeds of the Series 2021 PABs to its project site located at ADS.

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 PABs, (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 PABs.

**Disclosure Controls and Procedures**<br>

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in company reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Pursuant to Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), with the participation of other members of management, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2022. Our management does not expect that our disclosure controls and procedures will prevent or detect all errors and all fraud. Disclosure controls and procedures, no matter how well designed, operated and managed, can provide only reasonable assurance that the objectives of the disclosure controls and procedures are met. Because of the inherent limitations of disclosure controls and procedures, no evaluation of such disclosure controls and procedures can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Based upon this evaluation of our disclosure controls and procedures, our Chief Executive Officer and our Chief Financial Officer determined that our disclosure controls and procedures were effective as of December 31, 2022.<br>**Management**'**s Report on Internal Controls over Financial Reporting**

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. The Company's internal control system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management conducted an assessment of our internal control over financial reporting based upon criteria established in *Internal Control*—*Integrated Framework* issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013).
