Second Quarter Earnings and Related Discussion

Capstead reported GAAP net income of $15.5 million or $0.11 per diluted common share for the quarter ended June 30, 2021, compared to $18.9 million or $0.15 per diluted common share for the quarter ended March 31, 2021. The Company reported core earnings of $13.8 million or $0.09 per diluted common share for the quarter ended June 30, 2021. This compares to core earnings of $17.4 million or $0.13 per diluted common share for the quarter ended March 31, 2021. See the “Non-GAAP Financial Measures” section of this release for more information on core earnings.

Yields on the Company’s portfolio of agency-guaranteed residential ARM securities averaged 1.14% during the second quarter of 2021, a decrease of 24 basis points from 1.38% reported for the first quarter of 2021. Yields declined due primarily to higher yield adjustments for investment premium amortization due to higher mortgage prepayments, as well as lower coupon interest rates on existing loans that reset lower based on prevailing interest rates. Core earnings were also negatively impacted by lower average portfolio balances. Mortgage prepayment rates increased during the quarter to an average annualized constant prepayment rate (“CPR”) of 40.19%, compared to 37.12% CPR in the prior quarter. Portfolio leverage increased to 7.01 to one at June 30, 2021 compared to 6.79 to one at March 31, 2021.

The following table illustrates the progression of Capstead’s portfolio of residential mortgage investments for the quarter and six months ended June 30, 2021 (dollars in thousands):

	Quarter Ended June 30, 2021			Six Months Ended June 30, 2021
Residential mortgage investments, beginning of period	$	7,405,411		$	7,937,552
Portfolio acquisitions (principal amount)		974,119			1,361,949
Investment premiums on acquisitions		32,712			49,106
Portfolio runoff (principal amount)		(938,158	)		(1,832,153	)
Investment premium amortization		(22,411	)		(43,298	)
Decrease in net unrealized gains on securities classified as available-for-sale		(21,881	)		(43,364	)
Residential mortgage investments, end of period	$	7,429,792		$	7,429,792
Increase (decrease) in residential mortgage investments during the indicated periods	$	24,381		$	(507,760	)

Rates on Capstead’s secured borrowings, after adjusting for hedging activities, averaged five basis points lower at 0.15% during the second quarter of 2021, compared to 0.20% for the prior quarter. Borrowing rates before hedging activities averaged 0.14% during the second quarter, a decline of six basis points from the prior quarter. Secured borrowings ended the quarter at $6.81 billion.

Notional amounts of secured borrowings-related interest rate swap agreements averaged $3.47 billion during the second quarter of 2021 with fixed swap rates averaging 0.08%, four basis points higher than the prior quarter. At June 30, 2021, the Company held $4.25 billion notional amount of secured borrowings-related interest rate swaps with fixed rates averaging 0.11%, an increase of $1.03 billion in notional amount and five basis points in rate from swaps held on March 31, 2021. The Company’s duration gap, a measure of interest rate risk, decreased from approximately three and one-quarter months at March 31, 2021 to two months at June 30, 2021 – see page 10 for further information.

Book Value per Common Share

Book value per share as of June 30, 2021 was $6.35, a decrease of $0.31 for the quarter primarily reflecting $0.23 in portfolio-related declines in value, $0.04 in dividends distributed in excess of GAAP net income and $0.04 in derivative-related decreases. The fair value of the Company’s portfolio is expected to be less vulnerable to significant pricing declines caused by credit concerns or rising interest rates compared to leveraged portfolios containing a significant amount of non-agency-guaranteed securities or agency-guaranteed securities backed by longer-duration fixed-rate loans. Fair value is impacted by market conditions, including changes in interest rates and the availability of financing at reasonable rates and leverage levels.

Pending Merger with Benefit Street Partners Realty Trust

On July 26, 2021, the Company and Benefit Street Partners Realty Trust, Inc. (“BSPRT”), a publicly-registered non-listed middle market-focused commercial mortgage REIT, announced they have entered into a definitive merger agreement. Under the terms of the agreement, Capstead common stockholders will receive a cash payment equal to a 15.75% premium to Capstead’s

Page 2 of 12

adjusted book value per share and shares of BSPRT common stock calculated on an adjusted “book-for-book” basis. The book values for Capstead and BSPRT used to calculate the cash consideration and exchange ratio will be set on a date prior to the closing of the transaction pursuant to the merger agreement. Based on June 30, 2021 adjusted book values per share, the implied cash payment would be $0.99 per share and the total implied value would be $7.30 per share, representing an implied 20% premium to the last reported sale price of Capstead common stock on the New York Stock Exchange (“NYSE”) on July 23, 2021, which was the last trading day prior to the announcement of the merger. BSPRT will assume Capstead’s Series E preferred shares by exchanging them for new preferred shares of the combined company with the same terms.

At the closing, the combined company, which will be renamed Franklin BSP Realty Trust, will be the 4th largest publicly-traded commercial mortgage REIT with nearly $2 billion of pro forma stockholder equity and its common and preferred shares will be listed on the NYSE. It will be managed by Benefit Street Partners L.L.C., a wholly-owned subsidiary of Franklin Resources, Inc. (“Franklin Templeton”), a global investment management organization with over 70 years of investment experience and over $1.5 trillion in assets under management as of June 30, 2021.

The transaction, which is expected to close in the fourth quarter of 2021 and has been unanimously approved by both companies’ Boards of Directors, is subject to customary closing conditions, including the approval of Capstead’s common stockholders.

For further information about the proposed merger, see the Company’s and BSPRT’s joint press release and investor presentation issued on July 26, 2021.

Management Remarks

Commenting on second quarter results and market conditions, Phillip A. Reinsch, President and Chief Executive Officer, said, “Our second quarter results were impacted by continued high mortgage prepayment rates and lower investment in the portfolio since last fall due in large part to unacceptably low projected risk-adjusted returns on new investments. During the current quarter, we replaced second quarter portfolio runoff at projected returns in the upper single digits due in large part to increases in ARM production even as mortgage prepayments remained elevated.

“Interest rate volatility became more pronounced in June and into July as the markets digested prospects for inflation and the potential for a sooner than anticipated reduction in Federal Reserve monetary accommodation. Shorter-term rates increased and longer-term rates declined, flattening the yield curve back to February 2021 levels. Mortgage interest rates available to homeowners retraced much of the increase seen through April. This has increased prospects for future mortgage prepayments and has hindered pricing for residential mortgage securities, a negative for book values of residential mortgage REITs in general, including Capstead.”

Regarding the pending merger with BSPRT, Mr. Reinsch added, “The heavy involvement of the Federal Reserve in the agency MBS and U.S. Treasury markets, including its ongoing response to the COVID-19 pandemic, has lowered available returns and increased risks of holding

Page 3 of 12

agency MBS. For this reason and others, we believe combining with BSPRT represents a unique and value-maximizing opportunity for our stockholders to transition away from the agency MBS market into owning shares in a leading commercial mortgage REIT with a diversified, largely floating-rate credit strategy and proven track record capable of generating strong returns and cash flows. Importantly, our common stockholders will receive a significant cash premium at closing providing substantial immediate value.”

Non-GAAP Financial Measures

Management believes the presentation of core earnings and core earnings per common share, both non-GAAP financial measures, when analyzed in conjunction with the Company’s GAAP operating results, allows investors to more effectively evaluate the Company’s performance and provides investors management’s view of the Company’s economic performance.

Management also believes that presenting financing spreads on residential mortgage investments, a non-GAAP financial measure, provides important information for evaluating the performance of the Company’s portfolio, as opposed to total financing spreads, because this non-GAAP measure speaks specifically to the performance of the Company’s investment portfolio. See the “Reconciliation of GAAP Measures to Non-GAAP Measures” section of this release.

See “Reconciliation of GAAP Measures to Non-GAAP Measures” for details on the impact of non-designated derivative instruments.

(b)

Calculated using core earnings less preferred dividends on an annualized basis over average common equity for the period.

Gross WAC (rate paid by borrowers)^(d)				3.11

(a)

Amortized cost basis represents the Company’s investment (unpaid principal balance plus unamortized investment premiums) before unrealized gains and losses. At June 30, 2021, the ratio of amortized cost basis to unpaid principal balance for the Company’s ARM holdings was 103.89.

(b)

Net WAC, or weighted average coupon, is the weighted average interest rate of the mortgage loans underlying the indicated investments, net of servicing and other fees as of the indicated date. Net WAC is expressed as a percentage calculated on an annualized basis on the unpaid principal balances of the mortgage loans underlying these investments. As such, it is similar to the cash yield on the portfolio which is calculated using amortized cost basis. Fully indexed WAC represents the weighted average coupon upon one or more resets using interest rate indices and net margins as of the indicated date. Average net margins represent the weighted average levels over the underlying indices that the portfolio can adjust to upon reset, usually subject to initial, periodic and/or lifetime caps on the amount of such adjustments during any single interest rate adjustment period and over the contractual term of the underlying loans. ARM securities with initial fixed-rate periods of five years or longer typically have either 200 or 500 basis point initial caps with 200 basis point periodic caps. Additionally, certain ARM securities held by the Company are subject only to lifetime caps or are not subject to a cap. For presentation purposes, average periodic caps in the table above reflect initial caps until after an ARM security has reached its initial reset date and lifetime caps, less the current net WAC, for ARM securities subject only to lifetime caps. At quarter-end, 73% of current-reset ARMs were subject to periodic caps averaging 1.91%; 20% were subject to initial caps averaging 3.13%; and 7% were subject to lifetime caps averaging 8.05%.

(c)

Months-to-roll is a measure of the average length of time until the loans underlying each security reset to more current rates. After consideration of any applicable initial fixed-rate periods, at June 30, 2021 approximately 81%, 14% and 3% of the Company’s ARM securities were backed by mortgage loans that reset annually, semi-annually and monthly, respectively, while approximately 2% reset every five years. Approximately 80% of the Company’s current-reset ARM securities have reached an initial coupon reset date. Approximately 14% of the Company’s current-reset ARM securities are scheduled to reset in rate within three months, 44% are scheduled to reset in rate between four and six months, 27% are scheduled to reset in rate between seven and 12 months, and 15% are scheduled to reset in rate between 13 and 18 months.

(d)

Gross WAC is the weighted average interest rate of the mortgage loans underlying the indicated investments, including servicing and other fees paid by borrowers, as of the indicated balance sheet date.
