AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

CONDENSED NOTES TO FINANCIAL STATEMENTS

JUNE 30, 2026

(unaudited)

The adjustments made to these condensed financial 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 10‑K.

(2) Organization –

AEI Income & Growth Fund XXI Limited Partnership (the “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 (“ACC”).

Pursuant to Section 12.1(f) of the Partnership Agreement, the Managing General Partner can liquidate the Partnership upon the sale or other disposition of all or substantially all of its assets.

(4) Real Estate Investments –

In January 2025, the Partnership entered into an agreement to sell its 40% interest in the Jared Jewelry in Auburn Hills, Michigan to an unrelated third party. On March 31, 2025, the sale closed with the Partnership receiving net proceeds of $1,345,607, which resulted in a net gain of $825,611. At the time of sale, the cost and related accumulated depreciation was $1,466,048 and $946,052, respectively.

(5) Payable to Related Party –

AEI Fund Management, Inc. performs the administrative and operating functions for the Partnership. The payable to AEI Fund Management represents the balance due for those services. This balance is non-interest bearing and unsecured and is to be paid in the normal course of business.

(6) Partners’ Capital –

For the six months ended June 30, 2026 and 2025, the Partnership declared distributions of $329,505 and $541,013, respectively. The Limited Partners were allocated declared distributions of $326,210 and $535,603 and the General Partner was allocated declared distributions of $3,295 and $5,410 for the periods ended June 30, 2026 and 2025, respectively. The Limited Partners' declared distributions represented $20.42 and $32.40 per Limited Partnership Unit outstanding using 15,971 and 16,529 weighted average Units for the six months ended June 30, 2026 and 2025, respectively. The declared distributions represented $6.86 and $32.40 per Unit of Net Income and $13.56 and $0 per Unit of contributed capital for the six months ended June 30, 2026 and 2025, respectively.

During the six months ended June 30, 2026, the Partnership did not repurchase any Units from the Limited Partners.

On April 1, 2025, the Partnership repurchased a total of 1,095.87 Units for $787,350 from 45 Limited Partners in accordance with the Partnership Agreement. The Partnership acquired these Units using net sales proceeds. The repurchase increases the remaining Limited Partners' ownership interest in the Partnership. As a result of this repurchase and pursuant to the Partnership Agreement, the General Partner received distributions of $7,953 in the second quarter of 2025.

(7) Fair Value Measurements –

As of June 30, 2026 and December 31, 2025, the Partnership had no assets or liabilities measured at fair value on a recurring basis or nonrecurring basis.

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 Partner of conflicts with which they may be confronted;

—

the success of the General Partner 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, would 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 General Partner of the Partnership.

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 current economic factors, higher interest rates, and inflation in the US and globally, our tenants and operating partners may be impacted.

Results of Operations

For the six months ended June 30, 2026 and 2025, the Partnership recognized rental income of $447,533 and $473,876, respectively. In 2026, rental income decreased due to one property sale in March 2025, which was partially offset by two existing properties with rent increases in 2026. Based on the scheduled rent for the properties owned as of July 31, 2026, the Partnership expects to recognize rental income of approximately $896,000 in 2026.

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

For the six months ended June 30, 2026 and 2025, the Partnership incurred Partnership administration expenses from affiliated parties of $60,568 and $57,850, respectively. These administration expenses include costs associated with the management of the properties, processing distributions, reporting requirements and communicating with the Limited Partners. These expenses were higher in 2026, when compared to 2025, mainly due to higher costs associated with management of the properties. During the same periods, the Partnership incurred Partnership administration and property management expenses from unrelated parties of $61,065 and $82,997, 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. These expenses were lower in 2026, when compared to 2025, mainly due to fewer properties being managed as the Partnership is in the final liquidation process.

In January 2025, the Partnership entered into an agreement to sell its 40% interest in the Jared Jewelry in Auburn Hills, Michigan to an unrelated third party. On March 31, 2025, the sale closed with the Partnership receiving net proceeds of $1,345,607, which resulted in a net gain of $825,611. At the time of sale, the cost basis of the property and related accumulated depreciation was $1,466,048 and $946,052, respectively.

For the six months ended June 30, 2026 and 2025, the Partnership recognized interest income of $5,276 and $6,386, respectively.

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, 2026, the Partnership’s cash balances decreased $16,083 primarily as a result of distributions paid to the Partners in excess of cash generated from operating activities. During the six months ended June 30, 2025, the Partnership’s cash balances increased $550,323 as a result of cash received from the sale of real estate and cash received from operations, which was partially offset by distributions paid to Partners and cash used to repurchase Units in excess of cash generated from operating activities.

Net cash provided by operating activities decreased from $346,485 in 2025 to $315,313 in 2026 as a result of a decrease in total rental income which was partially offset by a decrease in Partnership administration and property management 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, 2026, the Partnership did not complete any property acquisitions or property sales. During the six months ended June 30, 2025, the Partnership generated cash flow from the sale of real estate of $1,345,607.

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, 2026 and 2025, the Partnership declared distributions of $329,505 and $541,013, which are to be distributed 99% to the Limited Partners and 1% to the General Partner, respectively. The Limited Partners were allocated declared distributions of $326,210 and $535,603 and the General Partner was allocated declared distributions of $3,295 and $5,410 for the periods ended June 30, 2026 and 2025, 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.

During the six months ended June 30, 2026, the Partnership did not repurchase any Units from the Limited Partners.

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, 2026 and December 31, 2025, 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.

ITEM 3. QUANTITATIVE & QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Not required for a smaller reporting company.

ITEM 4. CONTROLS AND PROCEDURES.

(a) Disclosure Controls and Procedures.

Under the supervision and with the participation of management, including its President and Chief Financial Officer, the Managing General Partner of the Partnership evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)). Based upon that evaluation, the President and Chief Financial Officer of the Managing General Partner concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and that such information is accumulated and communicated to management, including the President and Chief Financial Officer of the Managing General Partner, in a manner that allows timely decisions regarding required disclosure.

(b) Changes in Internal Control Over Financial Reporting.

Effective April 30, 2026, there was a transition of the principal financial officer role following the separation of the former Chief Financial Officer, Keith Petersen. Kristin Waddell was hired as the Chief Financial Officer effective May 4, 2026. There was no material change in the Partnership’s internal control over financial reporting as a result of this transition.

During the most recent period covered by this report, there has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(b) Not applicable.

(c) Pursuant to Section 7.7 of the Partnership Agreement, as amended, each Limited Partner has the right to present Units to the Partnership for purchase by submitting notice to the Managing General Partner during January or July of each year.

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. On April 1, 2025, the Partnership repurchased 1,095.87 Units. The Partnership did not repurchase any Units during the period ended June 30, 2026.
