Dear Stockholders,
On behalf of the Compensation Committee of the Board of Directors of Dynex 
Capital, Inc. ("the Company" or "Dynex"), we are writing to provide you with 
additional information to supplement the material in the Company's proxy 
statement ("Proxy Statement") for use at our 2024 Annual Meeting of 
Stockholders (the "Annual Meeting") to be held on Friday, May 17, 2024 at 9:00 
am Eastern Time. Specifically, we would like to provide additional context 
around the Company's executive compensation program that we believe will be 
helpful for stockholders.
Summary
.
Our Compensation Committee works with
Ferguson Partners Consulting L.P. ("FPC") as a compensation consultant to 
select an appropriate peer group for the Company.
Our peer group consists of internally managed public residential mortgage real 
estate investment trusts ("REITs") that have similar market capitalization 
(market capitalization correlates closely with capital in the REIT industry), 
that are similar to us based on business strategy, asset class focus, and the 
executives of the peers are required to have comparable skills and experience 
as the Company's executives. We have used this peer group consistently over 
the years, with appropriate updates, and we believe it properly correlates 
with the Company's business.

.
In 2023, we renegotiated the employment contracts of Byron Boston, our CEO, 
and Smriti Popenoe, our President and CIO, in connection with Mr. Boston's
assumption of the Chairman title, while continuing as CEO, and Ms. Popenoe's 
promotion to President and CIO. In that process, the
Compensation Committee increased their salaries and made a one-time bridge 
equity grant of restricted stock units ("RSUs"). The RSU grants were a 
one-time grant designed to further align compensation with the median 
compensation of the Company's peer group,
provide leadership stability for the Company and its shareholders, and provide 
appropriate incentives for the executive officers to focus on important 
strategic initiatives of the Company during the next several years as 
disclosed in the Proxy Statement.

How we develop our peer group
In determining the compensation of the Company's executive officers, the 
Compensation Committee engaged the services of FPC as a compensation 
consultant to assist the Committee in determining appropriate compensation 
levels for the executive officers using the executive compensation structures 
and the financial performance of a group of comparable companies. Our 
methodology for choosing peers, and the companies in the current peer group, 
have not materially changed in recent years.
The Company's peer group focuses principally on internally managed public 
residential mortgage REITs that have similar market capitalization, that are 
similar to us based on business strategy, asset class focus, and size, and the 
executives of which are required to have similar skills and experience as our 
executives. As an internally managed public mortgage REIT, capital is an 
important metric in assessing the Company's value. In the REIT industry, 
market capitalization correlates closely to capital. We would like to note 
that, for our business, capital is a more important financial metric for 
determining our peers than revenue. Capital indicates how much risk the 
management team is
                                       1

managing and the size of the Company's portfolio. Revenue can be influenced by 
operational or accounting factors that may not reflect the size and scope of 
the business or the complexity of the Company's operations. A peer group using 
solely revenue as a screening tool would result in a peer group that may not 
resemble the Company's direct competitors.
To attract and retain executives with the necessary skill sets and expertise 
to operate a company like Dynex, we believe it is imperative the Compensation 
Committee recognizes the metrics that are relevant in the REIT industry and 
benchmarks against a relevant peer group developed utilizing those metrics. 
The peer group used by our Compensation Committee, as recommended by FPC, is 
generally comprised of 5 to 10 companies that have comparable market 
capitalization within a range and are direct competitors or who are 
industry-relevant. The Compensation Committee determined to exclude externally 
managed mortgage REITs from our peer group due to the limited publicly 
available comparative compensation data for their executives.

How we set executive pay using our peers for 2023
Throughout the most recent contract period, which ended in 2023, the 
Compensation Committee monitored the target compensation of the Company's 
peers. In renegotiating the CEO's and CIO's contracts in 2023 in connection 
with Mr. Boston's
assumption of the Chairman title, while continuing as CEO, and Ms. Popenoe's 
promotion to President and CIO
, the Compensation Committee noted that their compensation had fallen below 
the median target compensation of the peer group. Based on the experience and 
performance of these executives, the Compensation Committee determined that it 
was appropriate for Mr. Boston and Ms. Popenoe to receive salary increases. 
The adjustments were made to move Ms. Popenoe and Mr. Boston closer to the 
median 2022 salary for the peer group based on the analysis reviewed by the 
Compensation Committee. Mr. Colligan's base salary was set at an annualized 
rate of $500,000 when he joined the Company in July 2022 and remained the same 
for 2023.
In connection with the contract negotiation, Ms. Popenoe and Mr. Boston were 
each granted RSUs with a market value of $1.5 million in September 2023 to 
bridge the gap between their former total compensation, which was below the 
median of the Company's peers, and the new total compensation, which is now 
closer in line with such peers. These bridge grants were one-time awards that, 
for 2023 only, changed the overall proportion of RSUs and performance share 
units (PSUs) granted in a year from the normal ratio of 60% PSU / 40% RSU to 
30% PSU / 70% RSU for our CEO and 26% PSU / 74% RSU for our President and CIO. 
The bridge grants were made to align compensation with peer companies, and 
they are not intended to recur each year. Beginning in 2024, Mr. Boston's, Ms. 
Popenoe and Mr. Colligan's equity targets were increased to be in line with 
peers going forward. We expect 2024 equity compensation grants to be based on 
our customary ratio of 60% PSU and 40% RSU.
The following table compares the 2022 compensation of CEOs of our peer group 
to the 2022 compensation of our CEO, in each case based on the proxy 
statements filed in 2023, and illustrates that our CEO's 2022 compensation was 
significantly below its peers:

Our confidence in our program
Dynex has historically had significant stockholder support of Say-on-Pay 
proposals in recent years, with 92% support on compensation matters in 2022 
and 2023. With the exception of the bridge grants and compensation increases 
in 2023, we have not materially changed the structure of our program in recent 
years. We continue to believe our pay, both in terms of target opportunity and 
design, is aligned with our appropriately constructed peer group.
As we discussed above, the compensation increases and bridge grants in 2023 
were made to align CEO and CIO compensation with peers and were granted 
concurrently with the CEO and CIO contract negotiations. Both executives took 
on new roles in 2023 as part of our strategic plan. Our CEO assumed the 
Chairman title and our President and CIO was promoted from the Co-CIO 
position. After their appointment, Dynex successfully executed a board 
refreshment process, which is discussed in the Proxy Statement. The Board and 
Compensation Committee believe it important to provide leadership stability 
for Dynex and its stockholders, and to provide appropriate incentives for the 
executive officers to focus on important strategic initiatives for Dynex.
We thank you for your continued support and request that you
vote "FOR" Proposal 2: Advisory Vote to Ratify Named Executive Officers' 
Compensation ("Say on Pay") at the upcoming 2024 Annual Meeting.
Sincerely,

The Compensation Committee
