CONDENSED NOTES TO FINANCIAL STATEMENTS

JUNE 30, 2022

(unaudited)

(1)  The condensed statements included herein have been prepared by the registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, and reflect all adjustments which are, in the opinion of management, necessary to a fair statement of the results of operations for the interim period, on a basis consistent with the annual audited statements. The adjustments made to these condensed statements consist only of normal recurring adjustments. Certain information, accounting policies, and footnote disclosures normally included in financial statements prepared in accordance with United States Generally Accepted Accounting Principles (US GAAP) have been condensed or omitted pursuant to such rules and regulations, although the registrant believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed financial statements be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in the registrant’s latest annual report on Form 10K.

(2)  Organization –

AEI Income & Growth Fund XXI Limited Partnership (“Partnership”) was formed to acquire and lease commercial properties to operating tenants. The Partnership's operations are managed by AEI Fund Management XXI, Inc. (“AFM”), the Managing General Partner. The Estate of Robert P. Johnson serves as the Individual General Partner. AFM is a wholly owned subsidiary of AEI Capital Corporation of which the Robert P. Johnson Trust and Patricia Johnson, own a majority interest. AEI Fund Management, Inc. (“AEI”), an affiliate of AFM, performs the administrative and operating functions for the Partnership.

In January 2021, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership’s properties and assets. On March 3, 2021, the votes were counted and neither proposal received the required majority vote. As a result, the Managing General Partner will continue the operations of the Partnership for an additional 60 months at which time it will ask the Limited Partners to vote on the same two proposals.

(3)  Recently Issued Accounting Pronouncements –

In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance.

Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Partnership or are not expected to have a significant impact on the Partnership’s financial positions, results of operations and cash flows.

(4)  Real Estate Investments –

The Partnership owned a 30% interest in the Gander Mountain store in Champaign, Illinois. The remaining interests in the property were owned by affiliates of the Partnership. On March 10, 2017, Gander Mountain Company filed for Chapter 11 reorganization and announced it was closing the store, following a liquidation sale of its onsite assets. In June 2017, the tenant filed a motion with the bankruptcy court to reject the lease for this store effective June 30, 2017. At this time, the tenant returned possession of the property to the owners and the Partnership became responsible for its 30% share of real estate taxes and other costs associated with maintaining the property. The tenant paid rent through June 2017.

On August 11, 2020, the Partnership entered into a lease agreement with a primary term of 10 years with Burlington Coat Factory of Texas, Inc. (“Burlington”) as a replacement tenant for 62% of the square footage of the property. The tenant’s obligations under the lease were guaranteed by Burlington Coat Factory Warehouse Corporation. The tenant was to operate a Burlington retail store in the space. The Partnership’s 30% share of annual rent was $102,980 and commenced on May 7, 2021. The Partnership was responsible for paying its 30% share of the buildout of the space, which was $612,992. As part of the agreement, the Partnership paid a tenant improvement allowance of $66,201 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $63,443 that were owed as part of the lease transaction. This amount was capitalized and was to be amortized over the term of the lease.

(4)  Real Estate Investments – (Continued)

On February 5, 2021, the Partnership entered into a lease agreement with a primary term of 10 years with Five Below, Inc. as a replacement tenant for 38% of the square footage of the property. The tenant operated a Five Below retail store in the space. The Partnerships 30% share of the annual rent was $62,093 and commenced on August 27, 2021. The Partnership was responsible for its 30% share of the buildout of the space, which was $250,988. As part of the agreement, the Partnership paid a tenant improvement allowance of $21,995 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $40,804 that were due as part of the lease transaction. This amount was capitalized and was to be amortized over the term of the lease.

In August 2021, the Partnership entered into an agreement to sell its 30% interest in the Burlington Coat Factory and Five Below in Champaign, Illinois to an unrelated third party. On September 28, 2021, the sale closed with the Partnership receiving net proceeds of $2,477,214, which resulted in a net gain of $13,198. At the time of the sale, the cost and related accumulated depreciation was $3,178,923 and $714,907, respectively.

In December 2021, the Partnership entered into an agreement to sell its 50% interest in the Jared Jewelry store in Hanover, Maryland to an unrelated third party. On February 14, 2022, the sale closed with the Partnership receiving net proceeds of $2,450,634, which resulted in a net gain of $1,268,078. At the time of sale, the cost and related accumulated depreciation was $1,989,135 and $806,579, respectively.

On March 22, 2022, the Partnership purchased a 40% interest of the Memorial Hospital property in Diamondhead, Mississippi for $1,610,422.  The Partnership allocated $114,052 of the purchase price to Acquired Lease Assets, representing in-place intangibles.  The property is leased to Memorial Hospital at Gulfport, Incorporated under a lease agreement with a remaining primary term of 5.3 years (as of date of purchase) and annual rent of $100,320 scheduled to increase annually at 2%.

On May 11, 2022, the Partnership purchased an additional 46% joint-venture interest in the Best Buy store in Eau Claire, Wisconsin for $3,726,043 from AEI Income & Growth Fund 26 LLC, an affiliate of the Partnership. The purchase price of the property was based upon the property’s fair market value as determined by an independent third party, commercial property appraiser. The property interest became available because AEI Income & Growth Fund 26 LLC was in the process of liquidating its property portfolio. The Partnership now owns 100% interest in the property. The Partnership allocated $306,653 of the purchase price to Acquired Intangible Lease Assets, representing in-place lease intangibles. The annual rent for the additional 46% interest that was purchased is $240,432.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS.

This section contains "forward-looking statements" which represent management's expectations or beliefs concerning future events, including statements regarding anticipated application of cash, expected returns from rental income, growth in revenue, the sufficiency of cash to meet operating expenses, rates of distribution, and other matters. These, and other forward-looking statements, should be evaluated in the context of a number of factors that may affect the Partnership's financial condition and results of operations, including the following:

—

Market and economic conditions which affect the value of the properties the Partnership owns and the cash from rental income such properties generate;

—

the federal income tax consequences of rental income, deductions, gain on sales and other items and the effects of these consequences for the Partners;

—

resolution by the General Partners of conflicts with which they may be confronted;

—

the success of the General Partners of locating properties with favorable risk return characteristics;

—

the effect of tenant defaults; and

—

the condition of the industries in which the tenants of properties owned by the Partnership operate.

Application of Critical Accounting Policies

The Partnership’s financial statements have been prepared in accordance with US GAAP. Preparing the financial statements requires management to use judgment in the application of these accounting policies, including making estimates and assumptions. These judgments will affect the reported amounts of the Partnership’s assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the financial statements and will affect the reported amounts of revenue and expenses during the reporting periods. It is possible that the carrying amount of the Partnership’s assets and liabilities, or the results of reported operations, will be affected if management’s estimates or assumptions prove inaccurate.

Management of the Partnership evaluates the following accounting estimates on an ongoing basis, and has discussed the development and selection of these estimates and the management discussion and analysis disclosures regarding them with the managing partner of the Partnership.

11

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

Allocation of Purchase Price of Acquired Properties

Upon acquisition of real properties, the Partnership records them in the financial statements at cost. The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the purchase price is based upon the relative fair value of each component of the property. Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management’s assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods. The above market and below market lease values will be capitalized as intangible lease assets or liabilities. Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease. These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The determination of the relative fair values of the assets and liabilities acquired will require the use of significant assumptions with regard to the current market rental rates, rental growth rates, discount and capitalization rates, interest rates and other variables. If management’s estimates or assumptions prove inaccurate, the result would be an inaccurate allocation of purchase price, which could impact the amount of reported net income.

12

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

Carrying Value of Properties

Properties are carried at original cost, less accumulated depreciation and amortization. The Partnership tests long-lived assets for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable. For properties the Partnership will hold and operate, management determines whether impairment has occurred by comparing the property’s probability-weighted future undiscounted cash flows to its current carrying value. For properties held for sale, management determines whether impairment has occurred by comparing the property’s estimated fair value less cost to sell to its current carrying value. If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value. Changes in these assumptions or analysis may cause material changes in the carrying value of the properties.

Allocation of Expenses

AEI Fund Management, Inc. allocates expenses to each of the funds they manage primarily on the basis of the number of hours devoted by their employees to each fund’s affairs. They also allocate expenses at the end of each month that are not directly related to a fund’s operations based upon the number of investors in the fund and the fund’s capitalization relative to other funds they manage. The Partnership reimburses these expenses subject to detailed limitations contained in the Partnership Agreement.

Factors Which May Influence Results of Operations

The Partnership is not aware of any material trends or uncertainties, other than national economic conditions affecting real estate generally, that may reasonably be expected to have a material impact, favorable or unfavorable, on revenues and investment property value. However, due to the outbreak and continuing effect of the coronavirus (COVID-19) in the U.S. and globally, our tenants and operating partners may be impacted.

Results of Operations

For the six months ended June 30, 2022 and 2021, the Partnership recognized rental income of $400,599 and $391,004, respectively. In 2022, rental income increased due to the purchase of two properties in 2022 and one property in 2021, which was partially offset by the sale of one property in 2022. Based on the scheduled rent for the properties owned as of July 31, 2022, the Partnership expects to recognize rental income of approximately $883,000 in 2022.

The Partnership owned a 30% interest in the Gander Mountain store in Champaign, Illinois. The remaining interests in the property were owned by affiliates of the Partnership. On March 10, 2017, Gander Mountain Company filed for Chapter 11 reorganization and announced it was closing the store, following a liquidation sale of its onsite assets. In June 2017, the tenant filed a motion with the bankruptcy court to reject the lease for this store effective June 30, 2017. At this time, the tenant returned possession of the property to the owners and the Partnership became responsible for its 30% share of real estate taxes and other costs associated with maintaining the property. The tenant paid rent through June 2017.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

On August 11, 2020, the Partnership entered into a lease agreement with a primary term of 10 years with Burlington Coat Factory of Texas, Inc. (“Burlington”) as a replacement tenant for 62% of the square footage of the property. The tenant’s obligations under the lease were guaranteed by Burlington Coat Factory Warehouse Corporation. The tenant was to operate a Burlington retail store in the space. The Partnership’s 30% share of annual rent was $102,980 and commenced on May 7, 2021. The Partnership was responsible for paying its 30% share of the buildout of the space, which was $612,992. As part of the agreement, the Partnership paid a tenant improvement allowance of $66,201 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $63,443 that were owed as part of the lease transaction. This amount was capitalized and was to be amortized over the term of the lease.

On February 5, 2021, the Partnership entered into a lease agreement with a primary term of 10 years with Five Below, Inc. as a replacement tenant for 38% of the square footage of the property. The tenant operated a Five Below retail store in the space. The Partnerships 30% share of the annual rent was $62,093 and commenced on August 27, 2021. The Partnership was responsible for its 30% share of the buildout of the space, which was $250,988. As part of the agreement, the Partnership paid a tenant improvement allowance of $21,995 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $40,804 that were due as part of the lease transaction. This amount was capitalized and was to be amortized over the term of the lease.

In August 2021, the Partnership entered into an agreement to sell its 30% interest in the Burlington Coat Factory and Five Below in Champaign, Illinois to an unrelated third party. On September 28, 2021, the sale closed with the Partnership receiving net proceeds of $2,477,214, which resulted in a net gain of $13,198. At the time of the sale, the cost and related accumulated depreciation was $3,178,923 and $714,907, respectively.

In July 2021, the Partnership entered into an agreement with the tenant of the Jared Jewelry store in Hanover, Maryland to extend the lease term seven years to end on January 31, 2029. As part of the agreement, the annual rent decreased from $224,340 to $167,500 effective February 1, 2022.

For the six months ended June 30, 2022 and 2021, the Partnership incurred Partnership administration expenses from affiliated parties of $74,967 and $80,206, respectively. These administration expenses include costs associated with the management of the properties, processing distributions, reporting requirements and communicating with the Limited Partners. During the same periods, the Partnership incurred Partnership administration and property management expenses from unrelated parties of $35,841 and $57,064, respectively. These expenses represent direct payments to third parties for legal and filing fees, direct administrative costs, outside audit costs, taxes, insurance and other property costs.

For the three months ended June 30, 2022 and 2021, the Partnership recognized interest income of $1,821 and $1,533, respectively.

14

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

Management believes inflation has not significantly affected income from operations. Leases may contain rent increases, based on the increase in the Consumer Price Index over a specified period, which will result in an increase in rental income over the term of the leases. Inflation also may cause the real estate to appreciate in value. However, inflation and changing prices may have an adverse impact on the operating margins of the properties' tenants, which could impair their ability to pay rent and subsequently reduce the Net Cash Flow available for distributions.

Liquidity and Capital Resources

During the six months ended June 30, 2022, the Partnership's cash balances decreased $3,119,826 as a result of cash used to purchase real estate, distributions paid to the Partners, and cash used to repurchase units in excess of cash generated from operating activities, which was partially offset by cash received from the sale of real estate. During the six months ended June 30, 2021, the Partnership's cash balances decreased $2,981,773 as a result of distributions paid to the Partners, cash used to repurchase units in excess of cash generated from operating activities, and cash used for property and lease acquisition costs.

Net cash provided by operating activities increased from $277,435 in 2021 to $382,114 in 2022 as a result of an increase in total rental income and interest income, a decrease in Partnership administration and property management expenses, and by net timing differences in the collection of payments from tenants and the payment of expenses.

The major components of the Partnership's cash flow from investing activities are investments in real estate and proceeds from the sale of real estate. During the six months ended June 30, 2022 and 2021, the Partnership generated cash flow from the sale of real estate of $2,450,634 and $0, respectively. During the same period, the Partnership expended $5,336,465 and $2,374,564 to invest in real properties.

In December 2021, the Partnership entered into an agreement to sell its 50% interest in the Jared Jewelry store in Hanover, Maryland to an unrelated third party. On February 14, 2022, the sale closed with the Partnership receiving net proceeds of approximately $2,451,000, which resulted in a net gain of approximately $1,268,000. At the time of sale, the cost and related accumulated depreciation was $1,989,135 and $806,579, respectively.

On March 22, 2022, the Partnership purchased a 40% interest of the Memorial Hospital property in Diamondhead, Mississippi for $1,610,422.  The Partnership allocated $114,052 of the purchase price to Acquired Lease Assets, representing in-place intangibles.  The property is leased to Memorial Hospital at Gulfport, Incorporated under a lease agreement with a remaining primary term of 5.3 years (as of date of purchase) and annual rent of $100,320 scheduled to increase annually at 2%.

15

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS. (Continued)

The Partnership's primary use of cash flow, other than investment in real estate, is distribution payments to Partners and cash used to repurchase Units. The Partnership declares its regular quarterly distributions before the end of each quarter and pays the distribution in the first week after the end of each quarter. The Partnership attempts to maintain a stable distribution rate from quarter to quarter. The Partnership may repurchase tendered Units on April 1st and October 1st of each year subject to limitations.

For the six months ended June 30, 2022 and 2021, the Partnership declared distributions of $343,940 and $263,633, respectively, which were distributed 99% to the Limited Partners and 1% to the General Partners. The Limited Partners were allocated distributions of $340,501 and $260,996 and the General Partners were allocated distributions of $3,439 and $2,637 for the periods, respectively.

The Partnership may repurchase Units from Limited Partners who have tendered their Units to the Partnership. Such Units may be acquired at a discount. The Partnership will not be obligated to purchase in any year any number of Units that, when aggregated with all other transfers of Units that have occurred since the beginning of the same calendar year (excluding Permitted Transfers as defined in the Partnership Agreement), would exceed 5% of the total number of Units outstanding on January 1 of such year. In no event shall the Partnership be obligated to purchase Units if, in the sole discretion of the Managing General Partner, such purchase would impair the capital or operation of the Partnership.

On April 1, 2022, the Partnership repurchased a total of 352.29 Units for $266,947 from 30 Limited Partners in accordance with the Partnership Agreement. On April 1, 2021, the Partnership repurchased a total of 843.97 Units for $610,604 from 36 Limited Partners. The Partnership acquired these Units using net sales proceeds.  As a result of these repurchases and pursuant to the Partnership Agreement, the General Partners received distributions of $2,696 and $6,168 in 2022 and 2021, respectively.

The continuing rent payments from the properties, together with cash generated from property sales, should be adequate to fund continuing distributions and meet other Partnership obligations on both a short-term and long-term basis.

Off-Balance Sheet Arrangements

As of June 30, 2022 and December 31, 2021, the Partnership had no material off-balance sheet arrangements that had or are reasonably likely to have current or future effects on its financial condition, results of operations, liquidity or capital resources.

Units tendered to the Partnership during January and July may be repurchased on April 1^st and October 1^st, respectively, of each year subject to the following limitations. The Partnership will not be obligated to purchase in any year more than 5% of the total number of Units outstanding on January 1 of such year. In no event shall the Partnership be obligated to purchase Units if, in the sole discretion of the Managing General Partner, such purchase would impair the capital or operation of the Partnership.

AEI Income & Growth Fund XXI Limited Partnership (“Partnership”) was formed to acquire and lease commercial properties to operating tenants. The Partnership's operations are managed by AEI Fund Management XXI, Inc. (“AFM”), the Managing General Partner. The Estate of Robert P. Johnson serves as the Individual General Partner. AFM is a wholly owned subsidiary of AEI Capital Corporation of which the Robert P. Johnson Trust and Patricia Johnson, own a majority interest. AEI Fund Management, Inc. (“AEI”), an affiliate of AFM, performs the administrative and operating functions for the Partnership.

In January 2021, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership’s properties and assets. On March 3, 2021, the votes were counted and neither proposal received the required majority vote. As a result, the Managing General Partner will continue the operations of the Partnership for an additional 60 months at which time it will ask the Limited Partners to vote on the same two proposals.

(3)  Recently Issued Accounting Pronouncements –

In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance.

Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Partnership or are not expected to have a significant impact on the Partnership’s financial positions, results of operations and cash flows.

The tenant paid rent through June 2017.

On August 11, 2020, the Partnership entered into a lease agreement with a primary term of 10 years with Burlington Coat Factory of Texas, Inc.

On February 5, 2021, the Partnership entered into a lease agreement with a primary term of 10 years with Five Below, Inc. as a replacement tenant for 38% of the square footage of the property. The tenant operated a Five Below retail store in the space. The Partnerships 30% share of the annual rent was $62,093 and commenced on August 27, 2021. The Partnership was responsible for its 30% share of the buildout of the space, which was $250,988.

The purchase price of the property was based upon the property’s fair market value as determined by an independent third party, commercial property appraiser. The property interest became available because AEI Income & Growth Fund 26 LLC was in the process of liquidating its property portfolio. The Partnership now owns 100% interest in the property. The Partnership allocated $306,653 of the purchase price to Acquired Intangible Lease Assets, representing in-place lease intangibles.
