## Opinion on the Financial Statement

We have audited the accompanying statement of financial condition of Armstrong Securities LLC (the "Company") as of December 31, 2025, and the related notes (collectively referred to as the "financial statement"). In our opinion, the financial statement presents fairly, in all material respects, the financial position of the Company as of December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

## Basis for Opinion

This financial statement is the responsibility of the Company's management. Our responsibility is to express an opinion on this financial statement based on our audit. 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 Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit 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 statement is free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the financial statement, 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 statement. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement. We believe that our audit of the financial statement provides a reasonable basis for our opinion.

#### Notes to Financial Statement December 31, 2025

#### 1. Organization and Nature of Business

Armstrong Securities LLC (the "Company"), incorporated under the state of Delaware on January 9, 2020. The Company is a broker-dealer registered with the U.S. Securities and Exchange Commission ("SEC") and is a member of the Financial Industry Regulatory Authority ("FINRA"), effective March 23, 2023. The Company is wholly-owned by Armstrong Securities Holdings LLC ("Parent"), a holding company. Armstrong Securities Holdings LLC is a wholly-owned subsidiary of EF Holdco Inc., which is a subsidiary of Ellington Financial Operating Partnership LLC, and is majority-owned ultimately by Ellington Financial Inc. ("EFC").

The Company is approved by FINRA to operate pursuant to the Securities Exchange Act ("SEA") Rule 15c3-3 (the Customer Protection Rule) and to engage in repurchase/reverse repurchase transactions, proprietary and agency based trading, underwriting, and private placement transactions and as a broker or dealer selling interests in mortgages or other receivables, U.S. government and corporate debt securities with institutional customers and other broker dealers.

#### 2. Summary of Significant Accounting Policies

#### Basis of Accounting

The Financial Statement is prepared using the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").

#### Use of Estimates

The preparation of Financial Statement in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the Financial Statement. Actual results could differ from those estimates.

#### Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of funds maintained in checking and money market accounts held at financial institutions and clearing brokers.

The Company's cash and cash equivalents are held principally at two financial institutions and at times may exceed federally insured limits. The Company has placed these funds in a high quality institution in order to minimize risk relating to exceeding insured limits.

The Company earns interest and dividend income on certain interest-bearing accounts. Interest income is recognized on an accrual basis. Of the \$1,805,096 cash balance, \$77,971 was invested in a Money Market fund.

#### Cash Segregated under Federal and Other Regulations

The Company has established a segregated special reserve bank account for the benefit of customers under SEC Rule 15c3-3. There was no reserve account balance required as of December 31, 2025.

{7}------------------------------------------------

Notes to Financial Statement December 31, 2025

#### Income Tax Policy

The Company is a disregarded entity of the Parent for income tax purposes and as such its activities are reported on the consolidated returns of EF Holdco Inc. As of December 31, 2025, the Company has no separate income tax provisions and has determined there were no uncertain tax positions based on an evaluation of ASC 740 - Accounting for Uncertainties Income Taxes .

#### Fair Value

The fair value of the Company's assets and liabilities which qualify as financial instruments in accordance with US GAAP approximate the carrying amounts presented in the Statement of Financial Condition.

The Company carries its securities owned at fair value. US GAAP establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are inputs that market participants would use in pricing the investment based on available market data. Unobservable inputs that reflect the Company's assumptions about the facts market participants would use in valuing the investment based on the best information in the market.

The fair value hierarchy is categorized into three levels based on the inputs as follow:

Level 1) Valuations based on unadjusted quoted prices in active markets for identical investments.

Level 2) Valuations based on (a) quoted prices in markets that are not active; (b) quoted prices for similar investments in active markets; (c) inputs other than quoted prices that are observable or inputs derived from or corroborated by observable market data correlation or otherwise.

Level 3) Valuations based on inputs that are unobservable, supported by little or no market activity, and significant to the overall fair value measurement.

An asset or liability's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

{8}------------------------------------------------

Notes to Financial Statement December 31, 2025

### Fair Value (Continued)

The availability of observable inputs can vary from financial instrument and is affected by a wide variety of factors, including, for example the type of product, whether the product is new and not yet established in the marketplace, the liquidity of markets, and other characteristic's particular to the transaction. 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 by management in determining fair value is greatest for instruments categorized in Level 3. The fair value of cash and money market funds, was estimated to be carrying value and classified as Level 1 of the fair value hierarchy.
