### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
**1.** **Reporting Entity and Significant Accounting Policies** 

Short Term Investment Fund for Puerto Rico Residents, Inc. (the "Fund") is a diversified open-end management investment company. The Fund is a corporation organized under the laws of the Commonwealth of Puerto Rico and is registered as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), as of May 14, 2021. Prior to such date and since inception, the Fund was registered and operated under the Puerto Rico Investment Companies Act of 1954, as amended. The Fund's offerings of securities are registered under the Securities Act of 1933, as amended. UBS Asset Managers of Puerto Rico (the "Investment Adviser"), a division of UBS Trust Company of Puerto Rico ("UBSTC"), is the Fund's Investment Adviser. UBSTC is also the Transfer Agent (the "Transfer Agent") and the Fund Administrator ("Administrator"). UBSTC has engaged State Street Bank and Trust Company to provide certain information and services including price quotations and calculations of the Fund's Net Asset Value ("NAV") per share.

The Fund's investment objective is to provide current income, consistent with liquidity and the conservation of capital. There is no assurance that the Fund will achieve its investment objective.

Certain charter provisions of the Fund might be void and unenforceable under the 1940 Act including, without limitation, provisions (i) permitting indemnification of officers and directors to the fullest extent permitted by Puerto Rico law, (ii) setting forth the required vote for changes to fundamental policies of the Fund, and (iii) stating that, to the fullest extent permitted by Puerto Rico law, no officer or director will be liable to the Fund or shareholders.

The following is a summary of the Fund's significant accounting policies:

#### Use of Estimates in Financial Statements Preparation
The Fund is an investment company that applies the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services-Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

#### NAV Per Share
The NAV per share of the Fund is determined by the Administrator daily after the close of trading on the New York Stock Exchange (NYSE), or if such day is not a business day in New York or Puerto Rico, on the next succeeding business day. The NAV per share is computed by dividing the total assets of the Fund less its liabilities, by the total number of shares outstanding.

#### Valuation of Investments
The Fund's assets are valued by State Street Bank and Trust Company on the basis of valuations provided by pricing services approved by Fund management and the Board of Directors (the "Board"). In arriving at their valuation, pricing sources may use both a grid matrix of securities values as well as evaluations of their staff. The valuation, in either case, is based on information concerning actual market transactions and quotations from dealers or a grid matrix performed by an outside vendor that reviews certain market and security factors to arrive at a bid price for a specific security. Certain Puerto Rico obligations have a limited number of market participants and, thus, might not have a readily ascertainable market value and may have periods of illiquidity. If the Fund has securities for which quotations are not readily available from any source, they will be fair valued by or under the direction of the Investment Adviser utilizing quotations and other information

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
concerning similar securities obtained from recognized dealers. The Investment Adviser can override any price that it believes is not consistent with market conditions. Valuation adjustments are limited to those necessary to ensure that the financial instrument's fair value is adequately representative of the price that would be received or paid in the marketplace. These adjustments include amounts that reflect counterparty credit quality, constraints on liquidity, and unobservable parameters that are applied consistently.

The Board has designated the Investment Adviser as the valuation designee pursuant to Rule 2a-5 of the 1940 Act and has delegated to the Investment Adviser the responsibility for making fair value determinations with respect to portfolio holdings. The Investment Adviser has established a Valuation Committee (the "Committee") which is responsible for overseeing the pricing and valuation of all securities held by the Fund. The Committee operates under pricing and valuation policies and procedures established by the Investment Adviser and approved by the Board. The policies and procedures set forth the mechanisms and processes to be employed on a weekly basis related to the valuation of portfolio securities for the purpose of determining the NAV of the Fund. The Committee reports to the Board on a regular basis.

GAAP provides a framework for measuring fair value and expands disclosures about fair value measurements and requires disclosure surrounding the various inputs that are used in determining the fair value of the Fund's investments. These inputs are summarized in three broad levels listed below.

● Level 1 - Quoted prices in active markets for identical assets and liabilities at the measurement date. An active market is one in which transactions for the assets occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

● Level 2 - Significant inputs other than quoted prices included in Level 1 that are observable (including quoted prices for similar securities, interest rates, prepayments speeds, credit risk, etc.), either directly or indirectly.

● Level 3 - Significant unobservable inputs, for example, inputs derived through extrapolation that cannot be corroborated by observable market data. These are developed based on the best information available in the circumstances, which might include UBSTC's own data. Level 3 inputs will consider the assumptions that market participants would use in pricing the asset, including assumptions about risk (e.g., credit risk, model risk, etc.).

Securities and other assets that cannot be priced according to the methods described above are valued based on policies and procedures approved by the Committee. In the event that unobservable inputs are used when determining such valuations, the securities will be classified as Level 3 in the fair value hierarchy. Altering one or more unobservable inputs may result in a significant change to a Level 3 security's fair value measurement. The Fund maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Fair value is based upon quoted market prices when available

The estimated fair value may be subjective in nature and may involve uncertainties and matters of significant judgment for certain financial instruments. Changes in the underlying assumptions used in calculating fair value could significantly affect the results. Therefore, the estimated fair value may materially differ from the value that could actually be realized on sale.

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

The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with 60 days or less remaining to maturity.

Following is a description of the Fund's valuation methodologies used for assets measured at amortized cost which approximates fair value:

**US Government Agencies and Instrumentalities:** These securities are valued at amortized cost, which approximates fair value and are classified as Level 2.

The following is a summary of the Fund's portfolio by inputs used as of December 31, 2025, in valuing the Fund's assets carried at amortized cost, which approximates fair value:

|  US Government, Agencies and Instrumentalities | $- | $70059672 | $- | $70059672 |

There were no Level 3 securities during the period from July 1, 2025, to December 31, 2025.

There were no transfers into or out of Level 3 during the period from July 1, 2025, to December 31, 2025.

#### Taxation
As a registered investment company under the 1940 Act, the Fund will not be subject to Puerto Rico income tax for any taxable year if it distributes at least 90% of its taxable net investment income for such year, as determined for these purposes pursuant to section 1112.01(a)(2) of the Puerto Rico Internal Revenue Code of 2011, as amended. Accordingly, as the Fund intends to meet this distribution requirement, the income earned by the Fund is not subject to Puerto Rico income tax at the Fund level.

The Fund can invest in taxable and tax-exempt securities. In general, distributions of taxable income dividends, if any, to Puerto Rico individuals, estates, and trusts are subject to a Puerto Rico tax withholding of 15% of the dividends distributed if certain requirements are met. Moreover, distribution of capital gains dividends, if any, to (a) Puerto Rico individuals, estates, and trusts are subject to a Puerto Rico income tax of 15% of the dividends distributed and (b) Puerto Rico corporations are subject to a Puerto Rico income tax of 20% of the dividends distributed. Puerto Rico income tax withholdings are effected at the time of payment of the corresponding dividend. Individual shareholders may be subject to Puerto Rico alternate basic tax that can reach the rate of 24% on certain fund distributions. Certain Puerto Rico entities receiving taxable income dividends are entitled to claim an 85% dividends received deduction.

For U.S. federal income tax purposes, the Fund is treated as a foreign corporation and does not intend to be engaged in a trade or business within the United States. As a foreign corporation not engaged in a trade or business in the United States, the Fund should generally not be subject to U.S. income tax on gains derived from the sale or exchange of personal property. Nevertheless, if it is determined that the Fund is engaged in a trade or business within the United States for purposes of the U.S. Internal Revenue Code of 1986, as amended ("U.S. Code"), and the Fund has taxable income that is effectively connected with such U.S. trade or business, the Fund will be subject to regular U.S. corporate income tax on its effectively connected taxable income, and maybe to a 30%

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
branch profits tax and state and local taxes as well. Also, the Fund is subject to a 30% U.S. withholding tax on certain types of income from sources within the U.S., such as dividends and interest.

An investment in the Fund is designed solely for Puerto Rico residents due to the Fund's specific tax features. The Fund does not intend to qualify as a Regulated Investment Company ("RIC") under Subchapter M of the U.S. Internal Revenue Code of 1986, as amended, and consequently an investor that is not (i) an individual who has his or her principal residence in Puerto Rico or (ii) a person, other than an individual, that has its principal office and principal place of business in Puerto Rico will not receive the tax benefits of an investment in a typical U.S. mutual fund (such as RIC tax treatment, i.e., availability of pass-through tax status for non-Puerto Rico residents) and may have adverse tax consequences for U.S. federal income tax purposes. If United States holders (which includes, but is not limited to, (i) citizens and residents of the United States who are not Puerto Rico individuals and (ii) corporations organized in the United States) invest in the Fund, such United States holders generally will be taxed on any dividend or interest paid by the Fund as ordinary income at the time such holders receive the dividend or interest or when it accrues, depending on such holder's method of accounting for tax purposes. Additionally, United States holders will be taxed on any gain on the sale of an investment in the Fund.

FASB Accounting Standards Codification Topic 740, Income Taxes (ASC 740) requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax return to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the "more-likely-than-not" threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund's tax positions taken on its Puerto Rico income tax returns for all open tax years (the prior four tax years) and has concluded that there are no uncertain tax positions. On an ongoing basis, management will monitor the Fund's tax position to determine if adjustments to this conclusion are necessary. The Fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expenses in the Statement of Operations. During the period from July 1, 2025, to December 31, 2025, the Fund did not incur any interest or penalties.

#### Dividends and Distributions to Shareholders
Dividends from net investment income are declared daily and paid monthly. Such dividends will automatically be reinvested unless the shareholder elects to receive them in cash. Dividends that are reinvested are subject to Puerto Rico income tax under the same rules that apply to cash dividends. The Fund may also distribute out of its tax-exempt income and taxable income, if any, net capital gains. Shares earn dividends on the day they are purchased but not on the day they are sold.

#### Investments in Tax Secured Obligations ("TSOs") Issued by Puerto Rico Investment Companies
The Fund shall purchase only TSOs that are collateralized fully by a pledge of certain securities, as required by the rating agency to maintain the highest short-term rating. The Fund shall purchase only TSOs in which the Fund maintains a perfected security interest. No TSOs were purchased during the period from July 1, 2025, to December 31, 2025.

#### Securities Purchased Under Agreements to Re-Sell
Under these agreements, the Fund purchases securities and simultaneously commits to resell the securities to the original seller (a broker -dealer, other financial institution, or affiliated Funds) at an agreed upon date and price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased securities. When entering into repurchase agreements, it is the Fund's policy that a custodian takes possession of the underlying collateral, the value of which at least

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
equals the principal amount of the repurchase transaction, including accrued interest. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. These transactions are treated as financings and recorded as assets. There were no securities purchased under agreements to re-sell for the period from July 1, 2025, to December 31, 2025.

#### Operating Segments
The Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures (ASU 2023-007). Adoption of the new standard impacted financial statement disclosures only and did not affect the Fund's financial position or the results of its operations. The ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and required retrospective application for all periods presented within the financial statements.

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 asses its performance, and has discrete financial information available. The Asset Liability Committee ("ALCO") of the Fund's adviser acts as the Fund's CODM. Since its commencement, the Fund operates and is managed as a single operating segment, as the CODM monitors the operating results of the Fund as a whole and the Fund's strategic portfolio allocation is pre-determined in accordance with the term of its prospectus, based on a defined investment strategy which is executed by the Fund's portfolio managers as a team. The financial information in the form of the Fund's portfolio investments, geographic allocation, net investment income, total return, expense ratio and changes in net assets resulting from operations, which are used by the CODM to assess the segment's performance versus the Fund's comparative benchmark and to make resource allocation decisions for the Fund's single segment is consistent with that presented within the Fund's Financial Statements. The Accounting policies of the Fund are consistent with those described in these Notes to Financial Statement. Segment assets are reflected on the accompanying Statements of Assets and Liabilities as "total assets" and significant segment expenses are listed on the accompanying Statement of Operations.

#### Other
Security transactions are accounted for on trade date (the date the order to buy or sell is executed). Realized gains and losses on security transactions are determined on the identified cost method. Premiums and discounts on securities purchased are amortized using the interest method over the life or the expected life of the respective securities. Interest income is accrued on a daily basis, except when collection is not expected.

**4.** **Investment Transactions** 

The total amount of unaffiliated purchases of U.S. government agencies securities (including certificates of deposit, if any) and the proceeds from maturities from U.S. government agency securities was $6,507,081,835 and $6,505,700,000, respectively, for the period from July 1, 2025, to December 31, 2025.

No sales of investment securities occurred during the period from July 1, 2025, to December 31, 2025.

There were no affiliated transactions during the period.

**5.** **Concentration of Credit Risk** 

Concentration of credit risk that arises from financial instruments exists for groups of investors or counterparties when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions.

**6.** **Investment and Other Requirements and Limitations** 

The Fund is subject to certain requirements and limitations related to investments and leverage. Some of these requirements and limitations are imposed by statute or by regulation while others are imposed by procedures established by the Board. The most significant requirements and limitations are discussed below.

The Fund principally invests in U.S. high quality short-term instruments, including securities issued or guaranteed by the U.S. government, its agencies and instrumentalities and/or mortgage-backed securities. "Short-term" means instruments that mature in 397 calendar days or less from the date when the Fund acquires the instrument. The maturity of securities rated in the second highest short-term rating category by a nationally recognized statistical rating organization ("NRSRO") may not exceed 180 days. The Fund may also invest in longer-term bonds with only a short time remaining to maturity or that have variable interest rates or other special features that give them the financial characteristics of short-term debt. The Fund invests only in U.S. dollar-denominated instruments.

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
Although the Fund may invest in securities with maturities of up to 397 days, under normal conditions, the average duration of the securities in which the Fund invests is expected to be 30 days or less and is currently not expected to exceed a dollar-weighted average maturity of 90 days. The Fund will have a dollar-weighted average maturity of no more than three years. "Dollar-weighted average maturity" is calculated by taking the average length of time to maturity (fixed-rate) or the next interest rate reset (floating-rate) for each underlying instrument held by the Fund, weighted according to the relative holdings per instrument.

The Fund is not a money market fund and does not seek to maintain a stable NAV of $1.00 per share for the Class A and B Shares.

In particular, the Fund will not be subject to the requirements of Rule 2a-7 under the 1940 Act, which, among other things, contains strict issuer diversification, maturity, and credit quality requirements. The Fund, for example, may invest to a greater degree than a money market fund in securities rated in the second highest short-term rating category by a NRSRO and the Fund is less diversified than such a fund. You may have a greater risk of losing money than if you invested in a money market fund.

The above describes the Fund's current investment strategy. However, if the Fund is able to procure sufficient Puerto Rico securities which meet the Fund's investment criteria, the Fund intends to modify its current investment strategy and intends to invest in a portfolio of high quality tax-exempt short-term debt instruments of governmental and private issuers, including instruments issued by other Puerto Rico investment companies advised by or co-advised by the Investment Adviser. "High quality" means instruments that at the time of investment are rated within the two highest short-term rating categories by one or more NRSRO or that are unrated but deemed to be of comparable quality by the Investment Adviser. Pursuant to this investment strategy, the Fund may continue to hold these instruments even if their rating is downgraded. "Short-term" means instruments that mature in 397 calendar days or less from the date when the Fund acquires the instrument. The maturity of securities rated in the second highest short-term rating category by an NRSRO may not exceed 180 days. Pursuant to this investment strategy, the Fund may also invest in longer-term bonds with only a short time remaining to maturity or that have variable interest rates or other special features that give them the financial characteristics of short-term debt. As part of this investment strategy, the Fund would invest a significant amount of its assets in short-term securities of Puerto Rico issuers, including Puerto Rico municipal obligations, Puerto Rico mortgage-backed and asset-backed securities, TSOs of Puerto Rico investment companies (the majority of which will be obligations issued by investment companies for which, like the Fund, UBS Asset Managers of Puerto Rico acts as investment adviser or co-investment adviser), repurchase agreements and commercial paper.

Investments in mortgage-backed securities may include those issued or guaranteed by Government National Mortgage Association ("GNMA"), Federal National Mortgage Association ("FNMA") or Federal Home Loan Mortgage Corporation ("FHLMC"), as well as mortgage-backed securities that are not guaranteed or issued by GNMA, FNMA, FHLMC or any other government agency ("Private Label mortgage-backed securities"), and in either case may include collateralized mortgage obligations ("CMOs"). Private Label mortgage-backed securities are issued in connection with a securitization and represent a beneficial interest in a privately sponsored trust or other entity, the assets of which are mortgage loans or GNMA, FNMA, FHLMC or other mortgage-backed securities, including CMOs.

The Fund will not invest in mortgage-backed securities that represent residual interests except as may otherwise be approved by the Board.

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
Under this investment strategy, the Fund expects to invest a substantial amount (i.e., in excess of 10%), and from time to time a majority, of its total assets in TSOs.

A "Puerto Rico issuer" is any issuer that satisfies one or more of the following criteria: (i) issuers that are organized under the laws of Puerto Rico or that maintain their principal place of business in Puerto Rico; (ii) issuers that have securities traded principally in Puerto Rico; or (iii) issuers that, during the most recent fiscal year, derived at least 20% of their revenues or profits from goods produced or sold, investments made or services performed in Puerto Rico or that have at least 20% of their assets in Puerto Rico. A "non-Puerto Rico issuer" is any issuer that: (i) is organized under the laws of a jurisdiction other than Puerto Rico and maintains their principal place of business in a jurisdiction other than Puerto Rico; (ii) has securities traded principally in a jurisdiction other than Puerto Rico; and (iii) during the most recent fiscal year, derived less than 20% of their revenues or profits from goods produced or sold, investments made or services performed in Puerto Rico and that does not have at least 20% of their assets in Puerto Rico.

The Fund may invest up to 15% of its total assets in illiquid securities, including repurchase agreements with maturities in excess of seven days. The Fund may borrow up to 5% of its total assets (including the amount borrowed), and then only from banks as a temporary measure for extraordinary or emergency purposes, such as meeting redemption requests which might otherwise require untimely dispositions of portfolio securities.

**7.** **Basis of Distributions and Components of Distributable Earnings (Accumulated Loss)** 

Since all securities held by the Fund at December 31, 2025, were valued at amortized cost, which approximates fair value, due to their short term maturities, it does not take into account unrealized gains or losses.

For the period from July 1, 2025, to December 31, 2025, the Fund distributed from ordinary income of Class A shares a total of $798,366.

For the period from July 1, 2025, to December 31, 2025, the Fund distributed from ordinary income of Class B shares a total of $284,413.

**8.** **Risks and Uncertainties** 

The Fund is exposed to various types of risks, such as credit, interest rate, geographic, conflict of interest, and illiquid securities risks, among others. This list is qualified in its entirety by reference to the more detailed information provided in the offering documentation for securities issued by the Fund.

*Investment and Market Risk*. The Fund's investments may be adversely affected by the performance of U.S. and Puerto Rico investment securities markets, which, in turn, may be influenced by a number of factors, including, among other things, (i) the level of interest rates, (ii) the rate of inflation, (iii) political decisions, (iv) fiscal policy, and (v) current events in general. All securities may be subject to adverse market trends. The value and liquidity of the Fund's portfolio holdings may fluctuate in response to events specific to the companies or stock or bond markets in which a Fund invests, as well as economic, political, or social events in the United States, Puerto Rico or abroad. Markets can be volatile, and values of individual securities and other investments at times may decline significantly and rapidly. This may cause the Fund's portfolio to be worth less than the price originally paid for it, or less than it was worth at an earlier time. Market risk may affect a single issuer or the market as a whole. As a result, a portfolio of such securities may underperform the market as a whole. Recent market conditions and events, including a global public health crisis and actions taken by governments in response, may exacerbate such volatility and may continue to negatively affect the value and liquidity of individual securities, national economies, and global markets generally. Rapid changes in value or liquidity, which often are not anticipated and can relate to events not connected to particular investments, may limit the ability of the Fund to dispose of its assets at the value or time of its choosing and can result in losses. Because the Fund invests in investment securities, the Fund's NAV may fluctuate due to market conditions, and as a result you may experience a decline in the value of your investment in the Fund and you may lose money.

If the Board, including upon a recommendation from the Investment Adviser, determines in its sole discretion, that, due to the lack of appropriate investment opportunities or for other reasons, the Fund is no longer a manageable investment and/or may have insufficient assets available for the conduct of its business, the Fund may distribute cash to its shareholders to liquidate their investment or may transfer shareholders' accounts to another available investment option designated and agreed to by the Board in the UBS-FS. Master Account Agreement or other relevant document.

Puerto Rico and other countries and regions in which the Fund may invest where the Investment Adviser has offices or where the Fund or the Investment Adviser otherwise do business are susceptible to natural disasters (e.g., fire, flood, earthquake, storm, and hurricane), epidemics/pandemics or other outbreaks of serious contagious diseases. The occurrence of a natural disaster or epidemic/pandemic could, directly or indirectly, adversely affect and severely disrupt the business operations, economies, and financial markets of many countries (even beyond the site of the natural disaster or epidemic/pandemic) and could adversely affect the Fund's investment program or the Investment Adviser's ability to do business. In addition, terrorist attacks, or the fear of or the precautions taken in anticipation of such attacks, could, directly or indirectly, materially and adversely affect certain industries in which the Fund invests or could affect the countries and regions in which the Fund invests, where the Investment Adviser has offices or where the Fund or the Investment Adviser otherwise do business. Other acts of war (e.g., invasion, acts of foreign enemies, hostilities, and insurrection, regardless of whether war is declared) could also have a material adverse impact on the financial condition of industries or countries in which the Fund invests.

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
In addition, turbulence in financial markets and reduced liquidity in equity and/or fixed-income markets may negatively affect the Fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region, or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain and could affect companies worldwide. An outbreak of an infectious disease or serious environmental or public health concern-could have a significant negative impact on economic and market conditions, could exacerbate pre-existing political, social, and economic risks in certain countries or regions and could trigger a prolonged period of global economic slowdown, which may impact the Fund. To the extent the Fund is overweight in certain countries, regions, companies, industries, or market sectors, such positions will increase the risk of loss from adverse developments affecting those countries, regions, companies, industries, or sectors.

*Puerto Rico Concentration Risk.* The Fund is exposed to certain risks resulting from the reduced geographic diversification of its portfolio. The Fund's assets may be invested in securities of Puerto Rico issuers. In addition, the TSOs in which the Fund may invest are issued by investment companies that, in turn, are designed to invest primarily in Puerto Rico securities. Securities issued by the Puerto Rico government or its instrumentalities are affected by the central government's finances. That includes, but is not limited to, general obligations of Puerto Rico and revenue bonds, special tax bonds, or agency bonds. Over the past few years, many Puerto Rico government bonds as well as the securities issued by several Puerto Rico financial institutions have been downgraded. Currently, none of the bonds issued by the Puerto Rico government and its instrumentalities without credit enhancements carry an investment-grade credit rating.

Because the Fund may invest a substantial portion of its assets in Puerto Rico bonds, the Fund's NAV and cash flow may fluctuate due to market conditions affecting these securities. Any future developments in this respect could result in additional interruptions in cash flow on debt payments, which may result in more price volatility across Puerto Rico securities. There can be no assurance that any additional defaults by Puerto Rico and other Puerto Rico instrumentalities will not have an additional adverse impact on the Fund's net investment income.

Consequently, the Fund's performance may be more severely affected by economic, political, regulatory, or other factors adversely affecting issuers in Puerto Rico than a fund that is not concentrated in Puerto Rico issuers.

*Interest Rate Risk.* Interest rate risk is the risk that when interest rates rise, the value of the Fund's investments will fall as a result. That is because the value of short-term instruments is generally expected to fall when short-term interest rates rise and to rise when short-term interest rates fall. Also, the Fund's yield will tend to lag changes in prevailing short-term interest rates. This means that the Fund's income will tend to rise more slowly than increases in short-term interest rates. Similarly, when short-term interest rates are falling, the Fund's income will tend to fall more slowly. A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from mutual funds that hold large amounts of fixed income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund's performance.

*Credit Risk*. Credit risk is the risk that fixed income securities in the Fund's portfolio will decline in price or that the issuer will fail to make principal or interest payments when due because the issuer of the security experiences a decline in its financial condition. Changes in an issuer's credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. To the extent that the Fund will typically invest a substantial amount of its

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
assets in securities issued by other investment companies for which, like the Fund, UBS Asset Managers of Puerto Rico acts as investment adviser, and investing in similar types of assets, this risk may be magnified. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

*Extension Risk*. Extension risk is the risk that during periods of rising interest rates, the average life of certain types of securities may be extended because of the right of the issuer to defer payments or make slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration (the estimated period until the security is paid in full) making it more sensitive to changes in interest rates, and reduce the value of the security. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

*Prepayment Risk.* Prepayment risk is the risk that during periods of declining interest rates, the issuer of a security may exercise its option to pay principal earlier than scheduled in order to refinance at lower interest rates, forcing the Fund to reinvest in lower yielding securities. Prepayment reduces the yield to maturity and the average life of the security and also increases price fluctuation. This tendency of issuers to refinance debt with high interest rates during periods of declining interest rates may reduce the positive effect of declining interest rates on the market value of the Fund's securities.

*Municipal Securities Risk.* Municipal securities are obligations, often bonds and notes, issued by or on behalf of states, territories, and possessions of the United States and the District of Columbia and their political subdivisions, agencies, authorities, and instrumentalities, the interest on which is typically exempt from federal income tax. The Fund ordinarily invests in Puerto Rico municipal securities. From time to time, proposals to restrict or eliminate the federal income tax exemption from interest on municipal securities are introduced before Congress. Proposals also may be introduced before state legislatures. If such proposals were enacted, the availability of municipal securities and their value would be affected.

Municipal bonds are generally considered riskier investments than Treasury securities. The prices and yields on municipal securities are subject to change from time to time and depend upon a variety of factors, including general money market conditions, the financial condition of the issuer (or other entities whose financial resources are supporting the municipal security), general conditions in the market for tax-exempt obligations, the size of a particular offering and the maturity of the obligation, and the rating(s) of the issue.

Municipal securities risks include the ability of the issuer to repay the obligation, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for, and value of, municipal securities. Certain municipal securities, including private activity bonds, are not backed by the full faith, credit, and taxing power of the issuer. Additionally, if events occur after the security is acquired that impact the security's tax exempt status, the Fund and its shareholders could be subject to substantial tax liabilities.

Certain of the municipal obligations in which the Fund may invest present their own distinct risks. These risks may depend, among other things, on the financial situation of the government issuer, or, in the case of industrial development bonds and similar securities (including certain bonds offered by the Puerto Rico Industrial, Tourist, Educational, Medical and Environmental Control Facilities Financing Authority) on that of the entity supplying the revenues that are intended to repay the obligations. It is also possible that, as a result of litigation or other conditions, the power or ability of issuers or those other entities to meet their obligations for the repayment of principal and payment of interest may be materially and adversely affected.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
*Repurchase Agreements Risk.* The Fund may also engage in repurchase agreements, which are transactions in which the Fund purchases a security from a counterparty and agrees to sell it back at a specified time and price in a specified currency. If a repurchase agreement counterparty defaults, the Fund may suffer time delays and incur costs or possible losses in connection with the disposition of the securities underlying the repurchase agreement. In the event of a default, instead of the contractual fixed rate of return, the rate of return to the Fund will depend on intervening fluctuations of the market values of the underlying securities and the accrued interest thereon. In such an event, the Fund would have rights against the respective counterparty for breach of contract with respect to any losses resulting from those market fluctuations following the failure of such counterparty to perform.

*Mortgage-Backed Securities Risk*. Mortgage-backed securities (residential and commercial) represent interests in "pools" of mortgages. Mortgage-backed securities have many of the risks of traditional debt securities but, in general, differ from investments in traditional debt securities in that, among other things, principal may be prepaid at any time due to prepayments by the obligors on the underlying obligations. As a result, the Fund may receive principal repayments on these securities earlier or later than anticipated by the Fund. In the event of prepayments that are received earlier than anticipated, the Fund may be required to reinvest such prepayments at rates that are lower than the anticipated yield of the prepaid obligation. The rate of prepayments is influenced by a variety of economic, geographic, demographic, and other factors, including, among others, prevailing mortgage interest rates, local and regional economic conditions, and homeowner mobility. Generally, prepayments will increase during periods of declining interest rates and decrease during periods of rising interest rates. The decrease in the rate of prepayments during periods of rising interest rates results in the extension of the duration of mortgage-backed securities, which makes them more sensitive to changes in interest rates and more likely to decline in value (this is known as extension risk). Since a substantial portion of the assets of the Fund may be invested in mortgage-backed securities, the Fund may be subject to these risks and other risks related to such securities to a significant degree, which might cause the market value of the Fund's investments to fluctuate more than otherwise would be the case. In addition, mortgage-backed or other securities issued or guaranteed by FNMA, FHLMC, or a Federal Home Loan Bank are supported only by the credit of these entities and are not supported by the full faith and credit of the United States.

*Asset-Backed Securities Risk*. Asset-backed securities represent interests in "pools" of assets, including consumer loans or receivables held in trust. The receivables supporting asset-backed securities are generally automobile and credit card receivables but may also consist of other types of obligations. Asset-backed securities and the underlying receivables are not generally insured or

------

### Short Term Investment Fund for Puerto Rico Residents, Inc.

#### Notes to Financial Statements

#### For the period from July 1, 2025, to December 31, 2025 (Unaudited)
guaranteed by any government agency. However, in certain cases, such securities are collateralized by loans guaranteed by the U.S. Small Business Administration ("SBA"). The SBA is an independent agency of the United States. Asset-backed securities present risks similar to those of mortgage-backed securities. However, in the case of many asset-backed securities, the prepayment rates on the underlying assets have historically been less influenced by market interest rate fluctuations and therefore have been more stable. The frequent absence of a government guarantee creates greater exposure to the credit risk on the underlying obligations and depending on the structure, the credit risk of the sponsor of such obligations.

Asset-backed securities entail certain risks not presented by mortgage-backed securities, including the risk that in certain states it may be difficult to perfect the liens securing the collateral backing certain asset-backed securities. In addition, certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if the underlying borrower defaults.

*Illiquid Securities*. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. There presently are a limited number of participants in the market for certain Puerto Rico securities or other securities or assets that the Fund may own. That and other factors may cause certain securities to have periods of illiquidity. Illiquid securities include, among other things, securities subject to legal or contractual restrictions on resale that hinder the marketability of the securities.

In addition, as described below under "Conflicts of Interest Risk", for most of those securities the Fund may have to depend on its affiliates for liquidity; there may be no or few independent sources of liquidity. That is particularly true of the investment company obligations that will likely become the primary investments of the Fund. That and other factors may cause securities to become illiquid, which could hinder the Fund's ability to redeem your investment.

The Fund may invest up to 15% of its total assets in illiquid securities, including repurchase agreements with maturities in excess of seven days. As a result, among other things, investors might be delayed in receiving funds needed for securities purchases or other matters, which could have other adverse consequences.

*Conflicts of Interest Risk.* Conflicts of Interest Risk is the risk that the Investment Adviser and its affiliates, as well other investment companies advised by the Investment Adviser that issue TSOs purchased by the Fund, may have interests that compete with those of the Fund. Among other things, the Investment Adviser or its affiliates may engage in transactions directly with the Fund to the extent permitted by the 1940 Act. The Investment Adviser and its affiliates will also act in numerous other capacities in connection with the Fund and the Puerto Rico investment companies in which the Fund may invest. These relationships also make the Fund very dependent upon the Investment Adviser and its affiliates. To the extent that the Fund invests in TSOs issued by investment companies affiliated with the Investment Adviser, such investments present certain conflicts of interest, such as competing objectives with respect to the level of interest rates on the TSOs, and other related issues.

**9.** **Indemnifications** 

In the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses for indemnification and expects the risk of loss to be remote.
