Arca U.S. Treasury Fund
Annual Report
December 31, 2025

January 2026

This report covers operations of the Arca U.S. Treasury Fund (the “Fund”) for the fiscal year ended December 31, 2025. The Fund concluded the year with net assets of $443,597 across thirty-two different investors, up from $426,345 on December 31, 2024 representing an increase of 4%.

Arca U.S. Treasury Fund

The Fund’s investment objective is to seek maximum total return consistent with the preservation of capital. Over the course of the reporting period, the Fund purchased and maintained a portfolio of U.S. Treasury securities in accordance with the Funds investment strategy.

Bond Market Overview

In 2025, the U.S. bond market experienced continued volatility, driven by monetary policy decisions, incoming economic data, and broader global market dynamics. Treasury yields began the year at elevated levels, with the 10-year U.S. Treasury at 4.57% and the 3-month Treasury at 4.36%, resulting in a modestly upward-sloping yield curve at the start of the year.

As the year progressed, monetary policy became the primary driver of short-term interest rates. After holding the federal funds target range at 4.25%-4.50% through much of the year, the Federal Reserve initiated easing with a 25 basis point cut on September 17, 2025 to 4.00%-4.25%, followed by additional cuts in October (to 3.75%-4.00%) and December (to 3.50%-3.75%, effective December 11, 2025).

By year-end, short-term rates had declined materially, with the 3-month Treasury yield ending 2025 at 3.65%. Longer-term yields also moved lower but remained relatively elevated, reflecting persistent inflation concerns and continued economic strength. The 10-year Treasury yield ended the year at 4.18%.

Compared to year-end 2024, the Treasury yield curve in 2025 shifted lower at the short and intermediate maturities, reflecting increased confidence in Federal Reserve easing. This reduced the degree of inversion seen in prior periods and resulted in a modest steepening of the curve. Longer-dated yields were comparatively stable year over year, continuing to reflect longer-term inflation expectations and supply-related pressures rather than near-term monetary policy.

Inside the Portfolio

The Fund’s investment objective remains to seek maximum total return consistent with the preservation of capital. With both the Fund’s investment objective and the prevailing rate environment in mind, the Adviser continued to focus on capturing attractive income while managing interest rate risk through a disciplined approach to duration. Throughout 2025, the Fund sought to minimize duration exposure by rolling short-dated U.S. Treasury bills, primarily in the 3 and 6-month range. As of December 31, 2025, the Fund recorded annual returns of 4.02%, compared to 4.31% for the Bloomberg Short Treasury Total Return Value Index Unhedged.

Factors that Materially Affected the Fund’s Performance

In 2025, the Fund’s performance was primarily influenced by changes in short-term interest rates and evolving expectations for Federal Reserve policy. As the Federal Reserve began to ease monetary policy in the second half of the year, short-term Treasury yields declined, supporting returns for securities held at the front end of the yield curve. This environment favored shorter maturities, which benefited from higher starting yields and lower sensitivity to interest rate movements.

At the same time, continued volatility in longer-term Treasury yields, driven by macroeconomic uncertainty, ongoing Treasury issuance, and shifts in global demand for U.S. government debt, affected overall market conditions. Despite these dynamics, the Fund’s focus on short-dated U.S. Treasury securities helped limit duration risk and maintain stability, aligning performance with the Fund’s objective of capital preservation while capturing income opportunities.

Looking Ahead

Looking ahead to 2026, the U.S. bond market will continue to be influenced by economic conditions and the path of monetary policy. With the Federal Reserve having moved into an easing phase, expectations around the pace and extent of further policy adjustments will remain an important driver of market behavior, particularly at the short end of the yield curve.

While easing policy may support lower short-term interest rates, longer-term yields could remain influenced by economic resilience, inflation uncertainty, and ongoing U.S. Treasury issuance to fund fiscal needs. These factors may continue to create periods of volatility across the yield curve. Global developments, including shifts in foreign demand for U.S. Treasuries and geopolitical considerations, are also expected to remain important variables affecting market performance.

For investors, the environment may offer opportunities to generate income as interest rates stabilize at higher levels than those seen in the prior decade. However, disciplined positioning will remain important as markets adjust to changing economic and policy conditions.

3

In accordance with the Fund’s mandate, and in constructing the portfolio, the Adviser will continue to focus on capturing attractive yield opportunities while maintaining an emphasis on capital preservation and liquidity. The Adviser will also continue to evaluate enhancements to the Fund designed to improve flexibility and support long-term growth and adoption.

Fund Risks

An investment in the Fund involves risk including loss of principal. You may not have access to the money you invest for an extended period of time. • You may not be able to sell your shares at the time or in the quantity of your choosing regardless of how the Fund performs. • Investors should understand that the Fund’s shares are not currently listed on or available for trading through a national securities exchange or any other exchange, and a market for trading on an exchange may never be available to investors. Except for individually negotiated peer-to-peer transactions, there is currently no secondary market for ArCoins, and no such market is expected to develop. • Because you may not be able to sell your shares at the time or in the quantity of your choosing, you may not be able to reduce your exposure to the Fund in a market downturn. • An investment in the Fund may not be suitable for investors who may need the money they invested in a specified timeframe. • The amount of any distributions the Fund may pay is uncertain. There is no assurance that the Fund will maintain a particular level of distributions, nor is there any guarantee that the Fund will make distributions at any particular time. • Due to the emerging nature of blockchain use in securities transactions, the Fund anticipates that (other than monthly repurchase offers as described below) there will initially be limited to no liquidity in ArCoins due to low or no volume in peer-to-peer transactions. Investors should therefore initially expect greater price volatility in the secondary market than would be the case if the shares had greater liquidity. • The Fund will not invest, directly or indirectly, in digital assets, including digital securities. • Although shareholders can engage in peer-to-peer transactions using blockchain technology, the Transfer Agent will maintain the official record of the Fund’s shareholders.

The Fund is one of the first registered funds to offer digital asset securities and there are additional risks associated with this feature of the Fund, including regulatory risk, liquidity risk, emerging technology risk, operational and technology risk, and risks specifically associated with the Ethereum blockchain. For details regarding all of the risks described above, please review the prospectus.

Arca Capital Management, LLC serves as adviser to the Fund, distributed by Distribution Services, LLC (“ACA”), Member FINRA/SIPC. The Adviser and ACA are not affiliated.

Arca U.S. Treasury Fund
NOTES TO FINANCIAL STATEMENTS
December 31, 2025
1. ORGANIZATION

Arca U.S. Treasury Fund (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, closed-end management investment company. The Fund engages in a continuous offering of shares. The Fund operates as an interval fund pursuant to Rule 23c-3 under the 1940 Act and, pursuant to an Exemptive Order issued by the Securities and Exchange Commission (the “SEC”) on October 20, 2020, offers monthly repurchases of shares at net asset value. The Fund’s investment adviser is Arca Capital Management, LLC. (the “Adviser”). The Fund commenced operations on July 6, 2020.

The investment objective of the Fund is to seek maximum total return consistent with preservation of capital.

The Fund’s shares (“ArCoins” or “shares”) are available for purchase and can be transferred in peer-to-peer transactions on Ethereum, an open, public, distributed ledger that is secured using cryptography (referred to as a “blockchain”). Ethereum records transactions between two parties in a verifiable and permanent way, referred to as “immutability.” There are no share certificates and, because the shares can be transferred in peer-to-peer transactions using Ethereum’s blockchain technology, the shares are characterized herein as “digital securities.” Please refer to the Fund’s registration statement for additional information, including the costs and risks of effecting transactions on Ethereum and other risks associated with investing in the Fund (see “Peer-to-Peer Transactions,” “About the Digital Securities” and “Risks of Digital Securities”).

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Fund in preparation of its financial statements. The policies are in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The preparation of the financial statements 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 income and expenses for the period. Actual results could differ from those estimates. The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 “Financial Services - Investment Companies”.

An operating segment is defined 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 comprised of the portfolio manager and Chief Financial Officer of the Trust. 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.

Securities Valuation - Securities listed on an exchange are valued at the last reported sale price at the close of the regular trading session of the exchange on the business day the value is being determined, or in the case of securities listed on NASDAQ at the NASDAQ Official Closing Price. In the absence of a sale, such securities shall be valued at the mean between the current bid and ask prices on the primary exchange on the day of valuation. Debt securities, including U.S. government obligation (other than short-term obligations) are valued each day by an independent pricing service based on methods which include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type, indications as to values from dealers, and general market conditions or market quotations from a major market maker in the securities. The independent pricing service does not distinguish between smaller-sized bond positions known as “odd lots” and larger institutional-sized bond positions known as “round lots”. The Fund may fair value a particular bond if the adviser does not believe that the round lot value provided by the independent pricing service reflects fair value of the Fund’s holding. Short-term debt obligations having 60 days or less remaining until maturity, at the time of purchase, may be valued at amortized cost which approximates fair value.

11

Arca U.S. Treasury Fund
NOTES TO FINANCIAL STATEMENTS (Continued)
December 31, 2025

Valuation of Underlying Funds - The Fund may invest in portfolios of open-end or closed-end investment companies (the “Underlying Funds”). The Underlying Funds value securities in their portfolios for which market quotations are readily available at their market values (generally the last reported sale price) and all other securities and assets at their fair value according to the methods established by the board of directors of the Underlying Funds.

Open-end investment companies are valued at their respective net asset values as reported by such investment companies. The shares of many closed-end investment companies, after their initial public offering, frequently trade at a price per share that is different than the net asset value per share. The difference represents a market premium or market discount of such shares. There can be no assurances that the market discount or market premium on shares of any closed-end investment company purchased by the Fund will not change.

When determining the fair value of an asset, the Adviser will seek to determine the price that it might reasonably expect to receive from the current sale of that asset in an arm’s length transaction. Fair value is defined as the amount for which assets could be sold in an orderly disposition over a reasonable period of time, taking into account the nature of the asset. Fair value determinations are based upon all available factors that the Adviser and the Board deem relevant. Fair value pricing, however, involves judgments that are inherently subjective and inexact, since fair valuation procedures are used only when it is not possible to be sure what value should be attributed to a particular asset or when an event will affect the market price of an asset and to what extent. As a result, fair value pricing may not reflect actual market value, and it is possible that the fair value determined for a security will be materially different from the value that actually could be or is realized upon the sale of that asset.

The Fund utilizes various methods to measure the fair value of all of its investments on a recurring basis. U.S. GAAP establishes a hierarchy that prioritizes inputs to valuation methods. The three levels of input are:

Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities that the Fund has the ability to access.

Level 2 - 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 instrument in an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

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.

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.

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety, is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following tables summarize the inputs used as of December 31, 2025 for the Fund’s assets and liabilities measured at fair value:

Assets * Level 1 Level 2 Level 3 Total
U.S. Treasury Bills $ - $ 436,363 $ - 436,363
Money Market Fund 22,660 - - 22,660
Total $ 22,660 $ 436,363 $ - $ 459,023

Arca U.S. Treasury Fund
NOTES TO FINANCIAL STATEMENTS (Continued)
December 31, 2025

The Fund did not hold any Level 3 securities during the year ended December 31, 2025. There were no transfers between levels.

Security Transactions and Investment Income - Security transactions are accounted for on trade date basis. Interest income is recognized on an accrual basis. Discounts are accreted and premiums are amortized on securities purchased over the lives of the respective securities. Dividend income is recorded on the ex-dividend date. Realized gains or losses from sales of securities are determined by comparing the identified cost of the security lot sold with the net sales proceeds.

Dividends and Distributions to Shareholders - Dividends from net investment income are declared and distributed quarterly. Distributions from net realized capital gains are declared and distributed annually. Dividends from net investment income and distributions from net realized gains are recorded on ex-dividend date and determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These “book/tax” differences are considered either temporary (i.e., deferred losses, capital loss carry forwards) or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the composition of net assets based on their federal tax-basis treatment. Temporary differences do not require reclassification.

Federal Income Taxes - It is the Fund’s policy to qualify as a regulated investment company by complying with the provisions of the Internal Revenue Code that are applicable to regulated investment companies and to distribute substantially all of its taxable income and net realized gains to shareholders. Therefore, no federal income tax provision has been recorded.

The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Management has analyzed the Fund’s tax positions and has concluded that no liability for unrecognized tax benefits related to uncertain tax positions should be recorded for open tax years ended December 31, 2022-December 31, 2024, or is expected to be taken in the Fund’s December 31, 2025 year-end tax returns. The Fund identifies its major tax jurisdictions as U.S. Federal and foreign jurisdictions where the Fund makes significant investments. The Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next twelve months.

The Fund adopted the FASB Accounting Standards Update 2023-09, “Income Taxes (Topic 740) Improvements to Income Tax Disclosures” (“ASU 2023-09”), which establishes new income tax disclosure requirements and modifies or eliminates certain existing disclosure provisions. The amendments in this ASU are intended to address investor requests for more transparency about income tax information and to improve the effectiveness of income tax disclosures. The Fund’s adoption of ASU 2023-09 did not have a material impact on the Fund’s financial statements.

Indemnification - The Trust indemnifies its officers and Trustees for certain liabilities that may arise from the performance of their duties to the Trust. Additionally, in the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund expects risk of loss due to these warranties and indemnities to be remote.

3. INVESTMENT TRANSACTIONS AND ASSOCIATED RISKS

For the year ended December 31, 2025, the aggregate purchases and sales of investments (excluding U.S. Government & Agencies and other short-term investments) were $0 and $0, respectively.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareholders of Arca U.S. Treasury Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Arca U.S. Treasury Fund (the Fund), including the schedule of investments, as of December 31, 2025, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the related notes to the financial statements (collectively, the financial statements), and the financial highlights for each of the five years in the period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2025, the results of its operations for the year then ended, the changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period 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 Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights 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 Fund in accordance with 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 Fund 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 Fund’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 procedures included confirmation of securities owned as of December 31, 2025, by correspondence with the custodian. 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.

ARCA U.S. TREASURY FUND

PROXY VOTING POLICY AND PROCEDURES

Adopted as of December 11, 2019

Arca U.S. Treasury Fund (the “Fund”) has delegated its proxy voting responsibility to its investment adviser, Arca Capital Management, LLC (the “Adviser” or the “Firm”). The Proxy Voting Policies and Procedures of the Adviser are set forth below. The guidelines are reviewed periodically by the Adviser and the Fund’s Independent Trustees, and, accordingly, are subject to change. For purposes of these Proxy Voting Policies and Procedures described below, “Covered Persons” refers to employees and officers of the Adviser, “Clients” refers to the Adviser’s clients, including the Fund, “President” refers to the Adviser’s President, and “CCO” refers to the Adviser’s chief compliance officer.

A. Policy

Pursuant to the advisory agreement executed between the Adviser and the Fund, the Adviser retains the responsibility to vote proxies on behalf of the Fund. Since the Adviser intends to invest primarily in securities that do not issue proxies (i.e. US Treasury obligations), the Adviser does not anticipate that it will ever vote proxies as a result of the Fund’s investment strategy. The Adviser however, has adopted the following proxy voting procedures below that would govern its proxy voting activities were it ever in position to vote a proxy for a client asset.

B. Responsibility

The President is responsible for the implementation and monitoring of the Adviser’s Proxy Voting Policies and Procedures, including associated practices, disclosures and recordkeeping. The President may delegate responsibility for the performance of these activities (provided that he or she maintains records evidencing individuals to whom authority has been delegated) but oversight and ultimate responsibility remain with the President.

C. Procedures

The Adviser has adopted various procedures to implement the firm’s Proxy Voting policy and reviews to monitor and ensure that the Firm’s policy is observed, implemented properly and amended or updated, as appropriate. The procedures are as follows:

Proxy Voting Guidelines

The guiding principle by which the Adviser votes on all matters submitted to security holders is the maximization of the ultimate economic value of the Fund’s holdings. The Adviser does not permit voting decisions to be influenced in any manner that is contrary to, or dilutive of, the guiding principle set forth above. It is our policy to avoid situations where there is any conflict of interest or perceived conflict of interest affecting our voting decisions. Any conflicts of interest, regardless of whether actual or perceived, will be addressed in accordance with these policies and procedures.

It is the general policy of the Firm to vote on all matters presented to security holders in any Proxy, and these policies and procedures have been designed with that in mind. However, the Adviser reserves the right to abstain on any particular vote or otherwise withhold its vote on any matter if, in its judgment, the costs associated with voting such Proxy outweigh the benefits to Clients or if the circumstances make such an abstention or withholding otherwise advisable and in the best interest of our Clients.

While the guidelines included in the procedures are intended to provide a benchmark for voting standards, each vote is ultimately cast on a case-by-case basis, taking into consideration the Adviser’s contractual obligations to its Clients and all other relevant facts and circumstances at the time of the vote (such that these guidelines may be overridden to the extent Adviser believes appropriate).

As the Adviser provides investment advisory services to registered investment companies, it will vote any proxies for the Fund clients in accordance with any applicable investment restrictions of each Fund client, if applicable.

Conflicts of Interest in Connection with Proxy Voting

The President has responsibility to monitor proxy voting decisions for any conflicts of interests, regardless of whether they are actual or perceived. In addition, all Covered Persons are expected to perform their tasks relating to the voting of Proxies in a manner that is aligned with the economic interests of the Firm’s Clients. If at any time any Covered Person becomes aware of any potential or actual conflict of interest or perceived conflict of interest regarding the voting policies and procedures described herein or any particular vote on behalf of any Client, he or she should contact the Adviser’s President and/or CCO. If any Covered Person is pressured or lobbied either from within or outside of the Firm with respect to any particular voting decision, he or she should contact the Adviser’s CCO. The CCO will use his or her best judgment to address any such conflict of interest and ensure that it is resolved in the best interest of the Clients.

Record Keeping & Regulatory Reporting

For all proxies voted, the Adviser will retain all records related the manner in which it voted proxies for securities held by its Fund clients. The President will be responsible for maintaining all records related to the Firm’s proxy voting.

Form N-PX: On an annual basis, following the end of the 12-month period ending June 30, the Adviser will furnish to the administrator of its Fund clients a full record detailing all how the Firm voted all proxies for the prior 12-month period.

ITEM 13. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

While at Brencourt, Mr. Dorman was a member of the firm’s investment committee. Mr. Dorman’s experience also includes being senior trader with responsibility for trading of over $100 million in proprietary capital for both Merrill Lynch from March 2006 to September 2008 and Citadel Securities from September 2009 to December 2010 dealing in U.S. and international corporate bonds.

Compensation may include a variety of components and may vary from year to year based on a number of factors, including the relative performance of the Fund and other accounts managed by the portfolio manager measured against an identified peer group.

The principal components of compensation include a base salary, a discretionary bonus and various retirement benefits.

Base compensation. Generally, the portfolio manager will receive base compensation based on his seniority and/or position with the Fund, which may include the amount of assets supervised and other management roles within the Fund.

Discretionary compensation. In addition to base compensation, the portfolio manager may receive discretionary compensation, which can be a substantial portion of total compensation. Discretionary compensation can include a discretionary cash bonus paid to recognize specific business contributions and to ensure that the total level of compensation is competitive with the market, as well as participation in incentive plans.
