Non-GAAP Financial Measures

Distributable Earnings

Distributable Earnings is a non-GAAP measure defined as net interest income plus TBA Drop Income adjusted for the net coupon effect of interest rate swaps and futures contracts minus net operating expenses. Distributable Earnings is based on the historical cost basis of our Agency Securities, interest rate swaps and futures contracts. Distributable Earnings differs, potentially significantly, from net interest income and from net income (loss) (which includes realized gains and losses and market value adjustments).

For a portion of its Agency Securities the Company may enter into TBA forward contracts for the purchase or sale of Agency Securities at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date, but the particular Agency Securities to be delivered are not identified until shortly before the TBA settlement date. The Company accounts for TBA Agency Securities as derivative instruments if it is reasonably possible that it will not take or make physical delivery of the Agency Securities upon settlement of the contract. The Company may choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a “pair off”), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA Agency Security for a later settlement date. This transaction is commonly referred to as a “dollar roll.” The Company accounts for TBA dollar roll transactions as a series of derivative transactions.

Forward settling TBA contracts typically trade at a discount, or “Drop,” to the regular settled TBA contract to reflect the expected interest income on the underlying deliverable Agency Securities, net of an implied financing cost, which would have been earned by the buyer if the contract settled on the next regular settlement date. When the Company enters into TBA contracts to buy Agency Securities for forward settlement, it earns this “TBA Drop Income,” because the TBA contract is essentially equivalent to a leveraged investment in the underlying Agency Securities. The amount of TBA Drop Income is calculated as the difference between the spot price of similar TBA contracts for regular settlement and the forward settlement price on the trade date. The Company generally accounts for TBA contracts as derivatives and TBA Drop Income is included as part of the periodic changes in fair value of the TBA contracts that the Company recognizes currently in the Other Income (Loss) section of its Consolidated Statement of Operations.

Distributable Earnings and Distributable Earnings per common share

The Company believes that Distributable Earnings and Distributable Earnings per common share may be useful to investors because our Board of Directors may consider Distributable Earnings and Distributable Earnings per common share as part of its deliberations when determining the level of dividends on our common stock. Distributable Earnings and Distributable Earnings per common share tend to be more stable over time and this practice is designed to increase the stability of our common stock dividend from month to month. However, because Distributable Earnings is an incomplete measure of the Company’s financial performance and involves significant differences from net interest income and net income (loss) computed in accordance with GAAP, Distributable Earnings should be considered as supplementary to, and not as a substitute for, the Company’s net interest income and net income (loss) computed in accordance with GAAP as a measure of certain aspects of the Company’s financial performance.

Economic Interest Income, Economic Interest Expense, Economic Net Interest Income/Net Interest Spread and Economic Net Yield on Interest Earning Assets

The Company believes that these non-GAAP measures, which include the effects of TBA drop income and net interest income (expense) on interest rate swaps and futures contracts, may be useful to investors because they reflect items that we consider in the management of the Company’s investment portfolio and related funding. The Company believes that the inclusion in economic net interest income of interest rate swaps and futures contracts, which are recognized under GAAP in gain/loss on derivative instruments, is meaningful as interest rate swaps are the primary instrument the Company uses to economically hedge against fluctuations in the Company’s borrowing costs and their inclusion is more indicative of the Company’s total cost of funds than interest expense alone. It does not include all interest earning assets and interest bearing liabilities, such as cash collateral posted by counterparties. Accordingly, it is not a substitute for net interest income or net income (loss) determined in accordance with GAAP and should be considered as supplementary to such GAAP measures as a measure of certain aspects of the Company’s financial performance.

We rely on the decades of experience of our management team for (i) MBS securities portfolio analysis and selection, (ii) access to equity capital and repurchase financing at potentially attractive rates and terms, and (iii) hedging and liquidity strategies to moderate interest rate and MBS price risk. We prioritize maintaining common share dividends appropriate for the intermediate term rather than focusing on short-term market fluctuations.

Certain statements made in this presentation regarding ARMOUR Residential REIT, Inc. (“ARMOUR” or the “Company”), and any other statements regarding ARMOUR’s future expectations, beliefs, goals or prospects constitute “forward- looking statements” made within the meaning of the safe harbor provisions of the United States Private Securities Litigation Reform Act of 1995. Any statements that are not statements of historical fact (including statements containing the words “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions) should also be considered forward-looking statements. Forward looking statements include but are not limited to statements regarding the projections and future plans for ARMOUR’s business, growth and operational improvements. Because forward looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of ARMOUR’s control. A number of important factors could cause actual results or events to differ materially from those indicated by such forward-looking statements. Additional information concerning these factors and risks are contained in the Company’s most recent annual and quarterly reports and other reports filed with the Securities and Exchange Commission. ARMOUR assumes no obligation to update the information in this communication, except as otherwise required by law. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. This material is for information purposes only and does not constitute an offer to sell, a solicitation of an offer to buy, or a recommendation for any securities or financial instruments. The statements, information and estimates contained herein are based on information that the Company believes to be reliable as of today's date unless otherwise indicated. ARMOUR cannot guarantee future results, levels of activity, performance or achievements. Pricing and duration information are estimates provided by independent third-party providers based on models that require inputs and assumptions. Actual realized prices and durations will depend on a number of factors that cannot be predicted with certainty and may be materially different from estimates. AMOUNTS MAY NOT FOOT DUE TO ROUNDING. Estimates do not reflect any costs of operation of ARMOUR. THE INFORMATION PRESENTED HEREIN IS UNAUDITED AND NOT REVIEWED BY OUR INDEPENDENT PUBLIC ACCOUNTANTS. Disclaimers
