Management's Discussion of Fund Performance

For the Six Months Ended March 31, 2026

The Fund's primary investment objective is to receive current interest income exempt from federal income taxes as is available from municipal bonds, consistent with prudent investment management and preservation of capital. Capital appreciation achieved through an investment in equity securities is a secondary objective of the Fund.

Net Investment Income

The Fund's net investment income is primarily dependent upon interest rates at the times the bonds in the portfolio were purchased and, to a lesser extent, the amount of dividends received from the exchange-traded fund (ETF) and money market fund.

Net investment income for the six-month period was $264,263 or $21.33 per share compared with $289,650 or $23.38 per share for the six-month period ended March 31, 2025.

During the six-month period, interest income from the bond portfolio declined which was partially offset by additional dividend income from the ETF and money market fund. Expenses increased primarily due to an increase in legal expenses.

Valuation of Bonds and Net Asset Value

Because the municipal bonds in the Fund's portfolio are not actively traded and market quotations are not readily available, the bonds are stated at fair value. The fair value for each bond is provided by the Fund's custodian, who uses an evaluation methodology. The ETF is valued at the closing price supplied by a third-party pricing vendor.

The Fund's net asset value is calculated by subtracting the Fund's liabilities from its assets. The valuation of the Fund's most significant assets, its bond portfolio, is affected by market interest rates and maturity and call dates. When interest rates increase, the value of the bond portfolio decreases. When interest rates decrease, the value of the bond portfolio increases. Longer maturity dates magnify the effect of interest rate changes. The Fund's ETF holding, comprising 21.8% of its investments as of the reporting date, fluctuates with economic and market conditions.

The net asset value of the Fund was $25,164,167 or $2,031.01 per share at March 31, 2026, a decrease of $198,317 or $16.01 per share from September 30, 2025. This change was the result of a decline in unrealized appreciation of investments of $90,881 further reduced by income distributed in excess of net investment income and offset by a realized gain together netting to $107,436. There was significant volatility in the financial markets in March.

Management's Discussion of Fund Performance - Continued

For the Six Months Ended March 31, 2026

The weighted average maturity was 13.4 years, a decrease from the prior year-end weighted average maturity of 14 years.

Asset Allocation

In the pie chart below, the bond portion of the portfolio is allocated by state. The ETF portion is reported as a separate category.

Other

During the period, two bonds were called for proceeds of $575,000. Cash from these and previous dispositions was reinvested in bonds maturing in one to 15 years ($713,241) and in the ETF ($519,229). Portfolio turnover was 2%.

March 31, 2026 (unaudited)

1. Organization

Keyco Fund, Inc. (the "Fund") has registered under the Investment Company Act of 1940, as amended, as a closed-end, diversified management investment company. The Fund became qualified as a regulated investment company under the Internal Revenue Code on October 1, 1979. Management intends to distribute to the shareholders substantially all earnings from that date. The Fund's primary investment objective is to receive current interest income exempt from federal income taxes as is available from municipal bonds, consistent with prudent investment management and preservation of capital, and capital appreciation achieved through an investment in equity securities will be a secondary objective.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The Fund is an investment company that follows the accounting and reporting guidance of Accounting Standards Codification Topic 946 applicable to investment companies.

Security Valuations

Processes and Structure

The Fund's Board of Directors has adopted guidelines for valuing securities including in circumstances in which market quotes are not readily available. In the unlikely event that the entity that provides custodial services for the Fund is unable to value one or more bonds in the portfolio and an alternate resource is used for pricing, the Board is to be notified at its next regularly scheduled meeting.

Hierarchy of Fair Value Inputs

The Fund utilizes various methods to measure the fair value of most of its investments on a recurring basis. U.S. generally accepted accounting principles (GAAP) establishes a hierarchy that prioritizes inputs to valuation techniques used to measure fair value. The three levels of inputs are as follows:

โ— Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access at the measurement date.
โ— Level 2 - Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These inputs may include quoted prices for the identical instruments on an inactive market, prices for similar instruments in active markets, interest rates, yield curves, implied volatilities, credit spreads and market-corroborated inputs.
โ— Level 3 - Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available, representing the Fund's own assumptions about the assumptions a market participant would use in valuing the asset or liability, and would be based on the best information available.

2. Significant Accounting Policies - Continued

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

Fair Value Measurements

The fair value of the long-term state and municipal obligations is estimated using various techniques which may include information from actual trades for active issues. Evaluations are also based on reviews of current economic conditions, trading levels, spread relationships and the slope of the yield curve. Evaluations are also adjusted for various attributes such as discounts, premiums, credit, use of proceeds and callability. To the extent that the inputs are observable and timely, the values would be categorized in Level 2 of the fair value hierarchy; otherwise, they would be categorized as Level 3.

Equity securities, including exchange-traded funds for which market quotations are readily available, are valued at the closing price as supplied by a third-party pricing vendor on the primary exchange on which they are traded. Money market funds are valued at their net asset value per share. Both are categorized as Level 1 in the hierarchy.

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Securities
Level 1 Level 2 Level 3 Fair Value
Long-term state and municipal obligations** $ - $ 18,652,907 $ - $ 18,652,907
Exchange-traded fund** 5,490,230 - - 5,490,230
Money market fund 916,893 - - 916,893
Total $ 6,407,123 $ 18,652,907 $ - $ 25,060,030

The Fund did not hold any Level 3 assets during the six-month period ended March 31, 2026. It is the Fund's policy to recognize transfers into and out of Levels at the end of the reporting period.

** Refer to Portfolio of Investments in Securities for breakdown of municipal bonds and the exchange-traded fund held by the Fund.

Federal Income Taxes

It is the Fund's intention to continue to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its income to its shareholders. The Fund also intends to distribute sufficient net investment income and net capital gains, if any, so that it will not be subject to excise tax on undistributed income and gains. Therefore, no federal income tax or excise tax provision is required.

The cost of securities for federal income tax purposes is expected to approximate the cost for financial statement purposes. The Fund's distributable earnings on a tax basis are determined only at the end of each fiscal year. The unrealized appreciation (depreciation) as of March 31, 2026 was as follows:

Gross unrealized appreciation $ 1,413,226
Gross unrealized depreciation (506,990 )
Net unrealized appreciation $ 906,236
Cost of investment securities including short-term investments $ 24,153,794

The capital loss carryforward of $6,550 at September 30, 2025 qualifies to be carried forward for an unlimited period and will be used to offset any capital gains realized by the Fund in future years. The Fund will not make distributions from capital gains while a capital loss carryforward remains.

The Fund's management has reviewed all open tax years for federal tax returns and has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. There are no unrecognized tax benefits in the financial statements for March 31, 2026. The Fund's tax returns are subject to examination for federal purposes for the open tax years (2022-24) and for the tax return to be filed for 2025. The Fund has not been subject to interest and/or penalties on its tax return filings. The Fund identifies its major tax jurisdictions as the U.S. federal government and the State of Michigan.

In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires public entities, on an annual basis, to provide income tax disclosures, including income taxes paid disaggregated by jurisdiction. This ASU also includes certain other amendments to improve the effectiveness of income tax disclosures. The ASU is effective for annual periods beginning after December 15, 2024. Management has determined that there is no impact of the ASU on the Fund's financial statements.

Security Transactions and Related Income

The Fund follows industry practice and records security transactions on the trade date. Cost of securities sold is determined by specific identification. Distributions to shareholders are recorded on the ex-dividend date. Interest income is recognized on an accrual basis. Discounts and premiums on securities purchased are accreted or amortized using the constant yield method. Dividend income is recorded on the ex-dividend date.

Segment Reporting

The Fund has adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The CODM is the President and Chief Executive Officer of the Fund. The Fund operates as a single operating segment. The Fund's income, expenses, assets, changes in net assets resulting from operations and performance are regularly monitored and assessed as a whole by the CODM responsible for oversight functions of the Fund, using the information presented in the financial statements and financial highlights. Adoption of the standard impacted financial statement disclosures only and did not affect the Fund's financial position or results of its operations.

Use of Estimates

The preparation of financial statements in conformity with GAAP principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

3. Purchases and Dispositions of Securities

The cost of purchases and the proceeds from dispositions of securities, other than United States government obligations and short-term notes, aggregated $1,232,470 and $575,000, respectively, for the six months ended March 31, 2026.

4. Portfolio Management

The Fund does not retain the services of an investment adviser or a third-party portfolio manager. The Fund, acting through its officers and with the review provided by the Board of Directors, makes investment decisions internally.

5. Related Party Transactions

Administration fees incurred include $43,250 for accounting, transfer agent, administrative and general office support services provided by Tauber Enterprises, LLC, an entity owned by an officer of the Fund. The agreement is reviewed and renewed annually by the Fund's Directors

6. Risks and Uncertainties

The Fund invests primarily in municipal bonds and to a lesser extent in equity securities through exchange-traded funds and/or mutual funds. Municipal bonds are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with investments in municipal bonds, it is possible that changes in the values of the bonds could occur in the near term and that such changes could materially affect the amounts reported in the Statement of Assets and Liabilities. The ability of issuers of debt instruments held by the Fund to meet their obligations may also be affected by economic and political developments in a specific state or region. Based on its major holdings of bonds of Michigan issuers, the Fund is more exposed to risks of the State's major industries such as automotive, manufacturing and related industries. Equity securities are also exposed to risks based on economic and/or market conditions. Due to the level of risk associated with equity investments, it is possible that changes in the value of those securities could occur in the near term and that such changes could materially affect the amounts reported in the Statement of Assets and Liabilities

7. Capital Share Transactions

There were no transactions in capital stock for the year ended September 30, 2025 and the six-month period ended March 31, 2026.

8. Commitments and Contingencies

In the normal course of business, the Fund may enter into contracts that may contain a variety of representations and warranties and provide general indemnifications. The Fund's maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated; however, management considers the risk of loss from such claims to be remote.

9. Subsequent Events

Management has evaluated the impact of all subsequent events through the date these financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in these financial statements.
