SECOND QUARTER 2017 RESULTS

GLEN ALLEN, Va. -- Dynex Capital, Inc. (NYSE: DX) reported its second quarter 2017 results today. As previously announced, the Company's quarterly conference call to discuss these results is today at 10:00 a.m. Eastern Time and may be accessed using conference ID 54789102 via telephone in the U.S. at 1-866-392-3507 (internationally at 1-614-999-9383) or by live webcast which includes a slide presentation, the link for which is provided under “Investor Center” on the Company's website (www.dynexcapital.com).

Second Quarter 2017 Highlights

• Comprehensive income to common shareholders of $0.05 per common share and net loss to common shareholders of $(0.20) per common share

• Core net operating income to common shareholders, a non-GAAP measure, of $0.19 per common share

• Book value per common share of $7.38 at June 30, 2017 compared to $7.52 at March 31, 2017 and $7.18 at December 31, 2016

• Sold $271.4 million in hybrid ARMs during the quarter and entered into to-be-announced ("TBA") forward contracts for the purchase of 30-year fixed rate Agency RMBS with an if settled cost basis of $416.3 million at June 30, 2017

• Added a net $990.0 million in pay-fixed interest rate swaps to substantially mitigate the risk to higher funding costs and to adjust the hedge position for the addition of TBA securities

• Leverage of 5.2x shareholders’ equity at June 30, 2017 and leverage including the amortized cost basis of TBA securities (if settled) of 6.0x shareholders’ equity at June 30, 2017

• Dividend declared of $0.18 per common share

Management's Remarks

“We are pleased with the results for the second quarter,” commented Byron L. Boston, CEO. "The benefit of a diversified investment strategy of a combined CMBS and RMBS portfolio resulted in core net operating income to common shareholders of $0.19 per common share this quarter. While book value was down slightly for the quarter partially due to weakening prices of hybrid ARMs, our CMBS and CMBS IO portfolios continue to perform strongly."

Mr. Boston continued, “This quarter we increased our leverage and reallocated our capital from short duration lower yielding investments to 30-year fixed-rate Agency mortgage-backed securities given the compelling

1

opportunity relative to other sectors. We have continued to invest in this sector in the third quarter which will help drive earnings for the remainder of the year. Longer term we feel that there are potential strong tailwinds for the industry, and in particular, the prospects for mortgage REITs from housing finance reform.”

Earnings Summary

Comprehensive income to common shareholders for the second quarter of 2017 was $2.3 million compared to $26.6 million in the first quarter of 2017. Net loss to common shareholders was $(10.1) million for the second quarter of 2017 compared to net income of $6.6 million in the first quarter of 2017, the key components of which are explained below.

Core net operating income to common shareholders, a non-GAAP measure, was $9.3 million for the second quarter of 2017 versus $7.4 million for the first quarter of 2017. Core net operating income to common shareholders includes $1.4 million in drop income from TBA securities (discussed further below) for the second quarter of 2017, which the Company did not invest in during the first quarter of 2017. Please refer to "Use of Non-GAAP Financial Measures" below for more information on management's use of core net operating income and other non-GAAP measures. Reconciliations of all non-GAAP measures to GAAP measures are provided as a supplement to this press release.

Net interest income increased $1.2 million compared to the first quarter of 2017 primarily due to higher prepayment compensation of $2.2 million from CMBS and CMBS IO, partially offset by higher borrowing costs of $1.2 million as a result of increased short-term rates.

The Company recognized a loss on derivative instruments, net of $(15.8) million comprised primarily of a $(16.2) million decline in fair value of interest rate swaps due to lower swap rates during the quarter and $1.7 million in net realized and unrealized gains on TBA securities financed in the dollar roll market. TBA securities are forward contracts accounted for as derivative instruments in the Company's financial statements; however, management views TBA securities as the economic equivalent in all material respects of investing in and financing generic Agency fixed-rate RMBS through the repurchase agreement market. The $1.7 million in net realized and unrealized gains generated from TBA securities during the second quarter of 2017 consisted of $1.4 million in drop income and a $0.3 million increase in fair value. Drop income, which is derived from TBA dollar roll transactions, represents the difference in price between the near settling TBA contract and the price for the same contract with a later settlement date. This difference is also viewed by management as the economic equivalent of net interest income (interest income less implied financing cost) on the underlying Agency security from trade date to settlement date

Book Value and Economic Return

Book value per common share decreased $(0.14) to $7.38 at June 30, 2017 from March 31, 2017. Book value for the quarter was negatively impacted by the underperformance of assets versus our hedges, particularly our hybrid ARMs. Our hedges performed as expected as the yield curve flattened. Economic return on book value was 0.5% for the second quarter of 2017 and 7.8% for the first half of 2017. Economic return on book value is calculated

2

by dividing (i) the sum of dividends declared per common share and the change in book value per common share by (ii) beginning book value per common share.

Investments Summary

The Company’s average interest earning assets were $3.1 billion for the second quarter of 2017 compared to $3.2 billion for the first quarter of 2017. Average interest earning assets declined as the Company partially rotated out of variable-rate Agency RMBS and into TBA securities which are not included in average interest earning assets. For the second quarter of 2017, average interest earning assets and average TBA securities on an if-settled basis totaled $3.4 billion.

The following table summarizes activity, average balances, and annualized effective yields on the Company’s MBS portfolio for the second quarter of 2017:

Financing Summary

The Company's cost of funds increased 19 basis points for the second quarter of 2017 compared to the first quarter of 2017 primarily as a result of the increase in short-term interest rates. The following table summarizes the Company's borrowings by collateral type for the periods indicated:

(3) Total cost of funds includes amount recorded as a portion of "interest expense" in accordance with GAAP related to the accretion of the balance remaining in accumulated other comprehensive income as a result of the Company's discontinuation of hedge accounting effective June 30, 2013.

Hedging Activities

The Company uses interest rate swaps to mitigate the impact of higher interest rates on its earnings and book value. The Company added a net $990.0 million in pay-fixed interest rate swaps during the second quarter of 2017, given the potential for higher short-term interest rates as a result of the recent and projected increases in the Federal Funds rate as well as to hedge the Company's TBA position. During the second quarter of 2017, the Company had an average notional of $2.1 billion in effective interest rate swaps outstanding at a weighted average net pay-fixed rate of 1.30% versus an average notional of $1.3 billion in effective interest rate swaps at a weighted average net pay-fixed rate of 1.16% for the first quarter of 2017.

Company Description

Dynex Capital, Inc. is an internally managed real estate investment trust, or REIT, which invests in mortgage assets on a leveraged basis. The Company invests in Agency and non-Agency RMBS, CMBS, and CMBS IO.  Additional information about Dynex Capital, Inc. is available at www.dynexcapital.com.

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. 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 net interest earnings from our investments after operating expenses and preferred stock dividends. 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 costs, drop income on TBA securities, general and administrative expenses (GAAP), and preferred dividends. Management includes drop income in core net operating income and in adjusted net interest income because TBA securities are viewed by management as economically equivalent to holding and financing Agency RMBS using short-term repurchase agreements. Management also includes periodic interest costs from its interest rate swaps, which are included in "gain(loss) on derivatives instruments" on the Company's consolidated statements of comprehensive income, in adjusted net interest expense and in adjusted net interest income because interest rate swaps are used by the Company to economically hedge the Company's borrowing costs from repurchase agreements, and including periodic interest costs from interest rate swaps is a helpful indicator of the Company’s total cost of financing in addition to GAAP interest expense. 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. Because these non-GAAP financial measures include or exclude, as applicable, certain items used to compute GAAP net income to common shareholders, GAAP net interest income, or GAAP interest expense, 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. In addition, because not all companies use identical calculations, the Company's presentation of its non-GAAP measures may not be comparable to other similarly-titled measures of other companies.
