Arlington Asset Investment Corp. Reports Third Quarter 2023 Financial Results

McLean, VA, November 13, 2023 – Arlington Asset Investment Corp. (NYSE: AAIC) (the “Company,” “Arlington,” “we,” “us” or “our”) today reported financial results for the quarter ended September 30, 2023.

Third Quarter 2023 Financial Highlights

Third Quarter Investment Portfolio

As of September 30, 2023, the Company’s investment portfolio capital allocation was as follows (dollars in thousands):

MSR Related Investments

The Company is party to agreements with a licensed, U.S. government sponsored enterprise (“GSE”) approved residential mortgage loan servicer that enable the Company to garner the economic return of an investment in an MSR purchased by the mortgage servicing counterparty. The arrangement allows the Company to participate in the economic benefits of investing in an MSR without holding the requisite licenses to purchase or hold MSRs directly. Under the terms of the arrangement, the Company provides capital to the mortgage servicing counterparty to purchase MSRs directly and the Company, in turn, receives all the economic benefits of the MSRs less a fee payable to the counterparty. At the Company’s request, the mortgage servicing counterparty may utilize leverage on the MSRs to which the Company’s MSR financing receivables are referenced to finance the purchase of additional MSRs to increase potential returns to the Company. These transactions are accounted for as financing receivables in the Company’s consolidated financial statements.

The Company’s MSR financing receivable investments as of September 30, 2023 are summarized in the tables below (dollars in thousands):

As of September 30, 2023, the mortgage servicing counterparty had no draws outstanding under its credit facility collateralized by the MSRs to which the Company’s MSR financing receivables are referenced. The weighted average yield on the Company’s MSR financing receivables was 14.63% for the third quarter of 2023 compared to 13.79% for the second quarter of 2023, and the actual weighted-average constant prepayment rate (“CPR”) for the MSRs underlying the Company’s MSR financing receivables was 5.44% for the third quarter of 2023 compared to 5.19% for the second quarter of 2023. As of September 30, 2023, the valuation multiple of the MSRs underlying the Company's MSR financing receivables, calculated as the underlying MSR price divided by the weighted-average servicing fee, was 5.59x.

Credit Investments

The Company’s credit investments generally include mortgage loans secured by residential or commercial real property or MBS collateralized by residential or commercial mortgage loans or residential solar panel loans (“non-agency” MBS or ABS). As of September 30, 2023, the Company’s credit investment portfolio at fair value was comprised of the following (dollars in thousands):

As of September 30, 2023, the Company had $79.6 million in repurchase agreements outstanding with a weighted average rate of 6.08% and remaining weighted average maturity of 18 days secured by $88.5 million of non-agency MBS at fair value. As of September 30, 2023, the Company did not have any repurchase agreements outstanding secured by commercial mortgage loans.

Agency MBS

The Company’s agency MBS consist of residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by a government sponsored enterprise, such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”). As of September 30, 2023, the Company’s agency MBS investment portfolio was comprised of the following (dollars in thousands):

As of September 30, 2023, the Company's specified agency MBS investment portfolio was comprised of the following (dollars in thousands):

The Company’s weighted average yield on its specified agency MBS was 4.34% for the third quarter of 2023 compared to 4.26% for the second quarter of 2023, and the actual weighted-average CPR for the Company’s specified agency MBS was 5.31% for the third quarter of 2023 compared to 4.58% for the second quarter of 2023.

As of September 30, 2023, the Company's net short TBA agency MBS investment portfolio was comprised of the following (dollars in thousands):

As of September 30, 2023, the Company had $475.1 million of repurchase agreements outstanding with a weighted average rate of 5.48% and remaining weighted average maturity of 12 days secured by an aggregate of $499.3 million of agency MBS at fair value. The Company’s weighted average cost of repurchase agreement funding secured by agency MBS was 5.57% during the third quarter of 2023 compared to 5.14% during the second quarter of 2023.

The Company enters into various hedging transactions to mitigate the interest rate sensitivity of its cost borrowing and the value of its fixed-rate agency MBS and MSR financing receivables. Under the terms of the Company’s interest rate swap agreements, the Company pays or receives interest payments based on a fixed rate and pays or receives variable interest payments based upon the Secured Overnight Financing Rate (“SOFR”). As of September 30, 2023, the Company’s interest swap agreements were comprised of the following (dollars in thousands):

The Company’s weighted average net pay rate of its interest rate swap agreements was 0.95% during the third quarter of 2023 compared to 0.80% during the second quarter of 2023. Under GAAP, the Company has not designated these transactions as hedging instruments for financial reporting purposes and, therefore, all gains and losses on its hedging instruments are recorded to line item "investment and derivative gains (losses), net" in the Company’s financial statements.

Other Third Quarter 2023 Financial Highlights

The Company’s book value was $6.41 per common share as of September 30, 2023 compared to $6.64 per common share as of June 30, 2023. Book value per common share is calculated as total equity less the preferred stock liquidation preference divided by common shares outstanding plus vested restricted stock units convertible into common stock less unvested restricted common stock. The Company's fully diluted book value was $5.56 per common share as of September 30, 2023 compared to $5.77 per common share as of June 30, 2023. Fully diluted book value per share is calculated as total equity less the preferred stock liquidation preference divided by common shares outstanding, including unvested restricted common stock, plus vested restricted stock units convertible into common stock and performance-based restricted stock units expected to be earned or vested upon the closing of the previously announced proposed sale of the Company to Ellington Financial.

The Company’s “at risk” leverage ratio was 0.4 to 1 as of September 30, 2023 compared to 0.5 to 1 as of June 30, 2023. The Company’s “at risk” leverage ratio is calculated as the sum of the Company’s repurchase agreement financing, net payable or receivable for unsettled securities, net contractual price of TBA purchase and sale commitments and financing embedded in its MSR financing receivables less cash and cash equivalents compared to the Company’s investable capital measured as the sum of the Company’s shareholders’ equity and long-term unsecured debt.

Non-GAAP Earnings Available for Distribution

In addition to the results of operations determined in accordance with GAAP, we also report a non-GAAP financial measure "earnings available for distribution". We define earnings available for distribution as net income available to common stock determined in accordance with GAAP adjusted for the following items:

Realized and unrealized gains and losses recognized with respect to our mortgage related investments and economic hedging instruments, which are reported in line item “investment and derivative gain (loss), net” of our consolidated statements of comprehensive income, other than TBA dollar roll income and interest rate swap net interest income or expense, are excluded from the computation of earnings available for distribution as such gains on losses are not reflective of the economic interest income earned or interest expense incurred from our interest-bearing financial assets and liabilities during the indicated reporting period. Because our long-term-focused investment strategy for our mortgage related investment portfolio is to generate a net spread on the leveraged assets while prudently hedging periodic changes in the fair value of those assets attributable to changes in benchmark interest rates, we generally expect the fluctuations in the fair value of our mortgage related investments and economic hedging instruments to largely offset one another over time. In addition, certain of our investments are held by our TRS which is subject to U.S. federal and state corporate income taxes. In calculating earnings available for distribution, any income tax provision or benefit associated with gains or losses on our mortgage related investments and economic hedging instruments are also excluded from earnings available for distribution.

TBA dollar roll income (expense) represents the economic equivalent of net interest income (expense) generated from our transactions in non-specified fixed-rate agency MBS, executed through sequential series of forward-settling purchase and sale transactions that are settled on a net basis (known as “dollar roll” transactions). Dollar roll income (expense) is generated (incurred) as a result of delaying, or “rolling,” the settlement of a forward-settling purchase (sale) of a TBA agency MBS by entering into an offsetting “spot” sale (purchase) with the same counterparty prior to the settlement date, net settling the “paired-off” positions in cash, and contemporaneously entering another forward-settling purchase (sale) with the same counterparty of a TBA agency MBS of the same essential characteristics for a later settlement date at a price discount relative to the spot sale (purchase). The price discount of the forward-settling purchase (sale) relative to the contemporaneously executed spot sale (purchase) reflects compensation to the seller for the interest income (inclusive of expected prepayments) that, at the time of sale, is expected to be foregone as a result of relinquishing beneficial ownership of the MBS from the settlement date of the spot sale until the settlement date of the forward purchase, net of implied repurchase financing costs. We calculate dollar roll income (expense) as the excess of the spot sale (purchase) price over the forward-settling purchase (sale) price and recognize this amount ratably over the period beginning on the settlement date of the sale (purchase) and ending on the settlement date of the forward purchase (sale). In our consolidated statements of comprehensive income prepared in accordance with GAAP, TBA agency MBS dollar roll income (expense) is reported as a component of the overall periodic change in the fair value of TBA forward commitments within the line item “investment and derivative gain (loss), net.”

We utilize interest rate swap agreements to economically hedge a portion of our exposure to variability in future interest cash flows, attributable to changes in benchmark interest rates, associated with future roll-overs of our short-term repurchase agreement financing arrangements. Accordingly, the net interest income earned or expense incurred (commonly referred to as “net interest carry”) from our interest rate swap agreements in combination with repurchase agreement interest expense recognized in accordance with GAAP represents our effective “economic interest expense.” In our consolidated statements of comprehensive income prepared in accordance with GAAP, the net interest income earned or expense incurred from interest rate swap agreements is reported as a component of the overall periodic change in the fair value of derivative instruments within the line item “investment and derivative gain (loss), net.”

The following table provides a reconciliation of GAAP net income (loss) available (attributable) to common stock for the last four fiscal quarters (unaudited, dollars in thousands):

Earnings available for distribution is used by management to evaluate the financial performance of our long-term-focused, net interest spread-based investment strategy and core business activities over periods of time as well as assist with the determination of the appropriate level of periodic dividends to common stockholders. In addition, we believe that earnings available for distribution assists investors in understanding and evaluating the financial performance of our long-term-focused, net interest spread-based investment strategy and core business activities over periods of time as well as its earnings capacity.

A limitation of utilizing this non-GAAP financial measure is that the effect of accounting for all events or transactions in accordance with GAAP does, in fact, reflect the financial results of our business and these effects should not be ignored when evaluating and analyzing our financial results. In addition, our calculation of earnings available for distribution may not be comparable to other similarly titled measures of other companies. Therefore, we believe that earnings available for distribution should be considered as a supplement to, and in conjunction with, net income and comprehensive income determined in accordance with GAAP. Furthermore, there may be differences between earnings available for distribution and taxable income determined in accordance with the Internal Revenue Code. As a REIT, we are required to distribute at least 90% of our REIT taxable income (subject to certain adjustments) to qualify as a REIT and all of our taxable income in order to not be subject to any U.S. federal or state corporate income taxes. Accordingly, earnings available for distribution may not equal our distribution requirements as a REIT.
