Second Quarter 2019 and Other Recent Highlights

On June 20, 2019, the Company effected a 1-for-3 reverse stock split of its common stock whereby every three common shares issued and outstanding as of the close of market on that date were converted into one common share. All references to common shares and per common share amounts presented herein have been adjusted to reflect the effect of the reverse stock split for all periods presented.

• Comprehensive loss of $(0.45) per common share and net loss of $(4.98) per common share versus comprehensive income of $1.37 per common share and net loss of $(2.42) per common share in the prior quarter

• Core net operating income, a non-GAAP measure, of $0.43 per common share versus $0.53 per common share last quarter

• Book value per common share of $17.68 at June 30, 2019 compared to $18.71 at March 31, 2019 and $18.07 at December 31, 2018 and is estimated to have recovered approximately 1% since quarter end as spreads have tightened and interest rate hedges have gained in fair value

• Investment portfolio including TBA dollar roll positions increased to $6.1 billion at June 30, 2019 compared to $5.6 billion at March 31, 2019 due to net purchases of $0.9 million in primarily Agency RMBS and CMBS

• Leverage including TBA dollar roll positions increased to 9.4x shareholders’ equity at June 30, 2019 compared to 8.5x at March 31, 2019

• Net interest spread and adjusted net interest spread, a non-GAAP measure, of 0.76% and 1.03%, respectively, for the second quarter of 2019 compared to 0.84% and 1.19%, respectively, for the first quarter of 2019

Management's Remarks

Mr. Byron L.Boston, President and Chief Executive Officer commented, "Last quarter we identified two headwinds to near-term earnings, namely the inverted yield curve that resulted in stubbornly higher financing costs and lower mortgage rates driving higher prepayment rates. We expect these headwinds to persist through the end of the year, and as a result, we anticipate reducing our monthly common dividend to $0.15 per share for August. Looking ahead, we have noted that inverted yield curves historically last 6 to 9 months. Today's forward curve is pricing in a reversion to a steeper curve by mid-2020. This implies about a 100 basis point reduction in the U.S. Federal Funds rate, which should translate directly into lower financing costs for our portfolio. However, until the Federal Reserve actually reduces the Federal Funds rate several times, we expect elevated funding costs to persist."

"Our macroeconomic opinion is that the current situation is temporary and that conditions will evolve such that our financing costs will be materially reduced in the future. We continue to manage our diversified portfolio for the long-term, while generating above average dividends for our shareholders," Mr. Boston continued.

Mr. Boston added, "We remain optimistic about the long-term prospects for our business. Demographics and the need for private capital in the U.S. housing finance system are tailwinds, now enhanced by the potential for lower financing costs. In an environment where investors are faced with a growing number of fixed income assets offering negative or low yields globally, we believe that returns from high quality U.S. real estate assets, such as those in Dynex's diversified portfolio, offer a compelling investment opportunity. "

Second Quarter 2019 Earnings Summary

Comprehensive loss to common shareholders for the second quarter of 2019 of $(11.1) million consisted of a net loss to common shareholders of $(122.2) million and other comprehensive income of $111.1 million compared to comprehensive income to common shareholders for the first quarter of 2019 of $31.2 million, which consisted of a net loss to common shareholders of $(55.3) million and other comprehensive income of $86.5 million. The Company's net loss to common shareholders for the second quarter of 2019 primarily consisted of:

▪net interest income of $12.9 million

▪net loss on derivative instruments of $(117.5) million

▪net loss on sale of investments, net of $(10.4) million

▪general and administrative expenses of $(4.3) million, and

▪preferred stock dividends of $(3.2) million.

Despite a larger investment portfolio, net interest income decreased $0.7 million during the second quarter of 2019 due primarily to additional premium amortization on fixed rate Agency RMBS resulting from an increase in prepayment speeds while favorable prepayment compensation on CMBS IO declined. Net loss on derivative instruments consisted primarily of a net loss on interest rate swaps of $(127.8) million as a result of further declines in swap rates for a third consecutive quarter which was partially offset by other comprehensive income of $111.1 million from the increase in fair value of MBS as interest rates declined during the second quarter of 2019.

2

Core net operating income to common shareholders, a non-GAAP measure, was $10.6 million, or $0.43 per common share, for the second quarter of 2019 versus $12.1 million, or $0.53 per common share, for the first quarter of 2019 primarily due to a decline in adjusted net interest income of $1.6 million compared to the first quarter. The decline in adjusted net interest income was due to elevated financing costs versus LIBOR which lowered the net periodic interest benefit from interest rate swaps. In addition, adjusted net interest income declined due to the increase in premium amortization mentioned above and lower TBA drop income as dollar roll carry was negatively impacted by higher prices for mortgage-backed securities and higher prepayment expectations. Please refer to "Use of Non-GAAP Financial Measures" below for additional important information about non-GAAP measures.

Book Value Per Common Share

Book value per common share decreased to $17.68 at June 30, 2019 from $18.71 at March 31, 2019. This decrease of $(1.03) per common share net of the second quarter dividend of $0.54 per common share resulted in a quarterly total economic loss on book value per common share of (2.6)%. The decrease in book value was driven by the decline in fair value of interest rate hedges, net of the increase in fair value of the Company's MBS, due to lower interest rates during the quarter coupled with an increase in spreads on MBS. In particular, RMBS spreads widened versus related hedges largely on prepayment concerns but also due to certain technical factors such as the implementation of the Uniform Mortgage Backed Security by the GSEs.

Investments and Financing Details

Interest earning assets grew by approximately 13% compared to the first quarter due to net purchases of $0.9 million in primarily Agency RMBS and CMBS. The Agency RMBS purchases were predominantly 3.5% coupon to reduce exposure to prepayment risk. The Company financed these purchases using repurchase agreement borrowings, which increased leverage including TBA dollar roll positions to 9.4x shareholders' equity compared to 8.5x at March 31, 2019.

(1) CMBS IO includes Agency and non-Agency securities.

(2) The impact of TBA drop income on adjusted net interest spread includes the implied average funding cost of TBA dollar roll transactions during the periods indicated.

(3) Amount represents net periodic interest benefit of effective interest rate swaps outstanding during the period and excludes realized and unrealized gains and losses from changes in fair value of derivatives.

(4) Represents a non-GAAP measure.

The Company's net interest spread declined 8 basis points for the second quarter of 2019 compared to the first quarter of 2019 due primarily to declines in the effective yields on fixed-rate Agency RMBS and CMBS IO. Effective yield on Agency RMBS declined due to faster prepayments while effective yield on CMBS IO declined due to lower prepayment penalty compensation. Prepayments speeds on fixed-rate Agency RMBS were 9.4% versus 5.6% last quarter due to seasonal factors and the lower interest environment during the first half of 2019. Adjusted net interest spread declined 16 basis points due primarily to the aforementioned decline in asset yields and a lower net receive rate on interest rate swaps as a result of the decline in 3-month LIBOR over the quarter. In addition, higher prepayment expectations on Agency RMBS continued to impact pricing of TBA contracts, reducing TBA drop income and the net interest spread for TBA dollar roll transactions.

Hedging Summary

4

As interest rates rallied further during the second quarter of 2019, the Company modified its hedge position and lifted interest rate swaps with a notional balance of $2.9 billion at a weighted average pay-fixed rate of 2.70%. The Company subsequently added interest rate swaps with a notional balance of $1.5 billion at a weighted average pay-fixed rate of 2.17%.

The following table provides information related to the Company's average borrowings outstanding and interest rate swaps effective for the periods indicated:

	Three Months Ended
($ in thousands)	June 30, 2019			March 31, 2019
Average repurchase agreement borrowings outstanding	$	4,562,993		$	3,931,335
Average net TBAs outstanding - at cost (1)	579,353			722,264
Average borrowings and net TBAs outstanding	$	5,142,346		$	4,653,599
Average notional amount of interest rate swaps outstanding (excluding forward starting swaps)	$	4,765,220		$	4,154,778
Ratio of average interest rate swaps to average borrowings and net TBAs outstanding (1)	0.9			0.9
Average interest rate swap pay-fixed rate (excluding forward starting swaps)	2.33		%	2.37		%
Average interest rate swap receive-floating rate	2.60		%	2.75		%
Average interest rate swap net receive rate	(0.27		)%	(0.38		)%

(1) Because the Company executes TBA dollar roll transactions, which economically represent the purchase and financing of fixed-rate Agency RMBS, the average TBAs outstanding are included in the ratio calculation.

The following table summarizes the weighted average notional amount and rate of interest rate swaps held as of June 30, 2019 ⁽¹⁾:

($ in thousands)	Weighted Average Notional		Weighted Average Rate
Remainder of 2019	$	3,500,000	2.04	%
2020	2,926,503		2.10	%

2024	1,466,503		2.20	%
2025	1,440,000		2.20	%

(1) Additional interest rate swaps outstanding from 2026-2047 had an average balance of $307.6 million at a weighted average pay-fixed rate of 2.23% as of June 30, 2019.

The Company also entered into an aggregate notional balance of $3.0 billion in Eurodollar futures late in the second quarter at a weighted average rate of 1.56% as additional hedges of its book value exposure if interest rates subsequently increase. The Eurodollar futures aggregate notional balance represents the total notional balance of 3-month contracts with maturities between 2020 and 2021.

Use of Non-GAAP Financial Measures

In addition to the Company's operating results presented in accordance with GAAP, this release includes certain non-GAAP financial measures including core net operating income to common shareholders (including per common share), adjusted interest expense, adjusted net interest income and the related metrics adjusted cost of funds and adjusted net interest spread. Because these measures are used in the Company's internal analysis of financial and operating performance, management believes that they provide greater transparency to our investors of management's view of our economic performance. Management also believes the presentation of these measures, when analyzed in conjunction with the Company's GAAP operating results, allows investors to more effectively evaluate and compare the performance of the Company to that of its peers, although the Company's presentation of its non-GAAP measures may not be comparable to other similarly-titled measures of other companies. Schedules reconciling core net operating income to common shareholders, adjusted interest expense, and adjusted net interest income to GAAP financial measures are provided as a supplement to this release.

Management views core net operating income to common shareholders as an estimate of the Company's financial performance excluding changes in fair value of its investments and derivatives. In addition to the non-GAAP reconciliation set forth in the supplement to this release, which derives core net operating income to common shareholders from GAAP net income to common shareholders as the nearest GAAP equivalent measure, core net operating income to common shareholders can also be determined by adjusting net interest income to include interest rate swap periodic interest benefit (cost), drop income on TBA dollar roll transactions, general and administrative expenses, and preferred dividends. Management includes drop income, which is included in "gain (loss) on derivatives instruments, net" on the Company's consolidated statements of comprehensive income, in core net operating income and in adjusted net interest income because TBA dollar roll positions are viewed by management as economically equivalent to holding and financing Agency RMBS using short-term repurchase agreements. Management also includes periodic interest benefit (cost) from its interest rate swaps, which are also included in "gain (loss) on derivatives instruments, net", in adjusted net interest expense, and in adjusted net interest income because interest rate swaps are used by the Company to economically hedge the impact of changing interest rates on its borrowing costs from repurchase agreements, and including periodic interest benefit (cost) from interest rate swaps is a helpful indicator of the Company’s total cost of financing in addition to GAAP interest expense. However, these non-GAAP measures do not provide a full perspective on our results of operations, and therefore, their usefulness is limited. For example, these non-GAAP measures do not include gains or losses from available-for-sale investments, changes in fair value of and costs of terminating interest rate swaps, as well as realized and unrealized gains or losses from any instrument used by management to economically hedge the impact of changing interest rates on its portfolio and book value per common share, such as Eurodollar futures. As a result, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, the Company's GAAP results as reported on its consolidated statements of comprehensive income.
