 Company Summary  Proven Strategy of Efficiently Managing a Leveraged Portfolio of Short-Duration Agency-Guaranteed ARM Securities  Experienced Management TeamAligned with Stockholders  Overview of Capstead Mortgage Corporation  Founded in 1985, Capstead is the oldest publicly-traded residential mortgage REIT. Our sole focus is on managing a leveraged portfolio of short-duration* agency-guaranteed (i.e. Fannie Mae, Freddie Mac and Ginnie Mae) residential ARM securities that is appropriately hedged and can earn attractive risk-adjusted returns over the long term, with little, if any, credit risk.At June 30, 2016, our agency-guaranteed ARM securities portfolio stood at $13.90 billion, supported by $1.38 billion in long-term investment capital levered 9.28 times.       Our short-duration strategy differentiates us from our peers because the adjustable-rate mortgages underlying our portfolio reset to more current interest rates within a relatively short period of time:allowing us to benefit from future recoveries in financing spreads that typically contract during periods of rising interest rates, andresulting in smaller fluctuations in portfolio values from changes in interest rates compared to portfolios containing a significant amount of longer-duration ARM or fixed-rate mortgage securities.By virtue of being internally-managed and with our sole focus on agency-guaranteed securities, we are the most efficient mortgage REIT in the industry.  Our top three executive officers have a combined 75 years of mortgage finance industry experience.We are internally-managed with low operating costs and a strong focus on performance-based compensation. This structure greatly enhances the alignment of management interests with those of our stockholders.  3    This singular and straight-forward investment strategy, together with our use of cash flow hedge accounting allows for easily understood, transparent financial reporting, with limited use of non-GAAP financial measures.Additional transparency is evident by virtue of our internally-managed structure – our compensation-related decisions and costs are fully disclosed and subject to annual say-on-pay approvals.We make every effort to provide additional analysis in our earnings reports, SEC filings and analyst presentations that tells our story in a complete and straight-forward fashion.  Straight-forward Investment Strategy and Transparent Reporting  * Duration is a measure of market price sensitivity to interest rate movements. A shorter duration generally indicates less interest rate risk.

 Components of our Economic ReturnQuarterly Earnings, Dividends and Change in Book Value  5  Our quarterly earnings fluctuate with seasonal factors, most notably higher mortgage prepayment levels typically experienced during the summer house-selling season, and can also be affected by the impact of changes in interest rates on mortgage refinancing activity and on our borrowing costs.  We reassess the common dividend periodically based largely on how these factors are impacting expected future earnings.Changes in interest rates and other market conditions also directly impact our book value per common share as our portfolio and our hedge instruments are marked-to-market through stockholders’ equity, and to the extent common dividends exceed earnings resulting in a return of capital to our stockholders.  For presentation purposes, we adjusted our diluted EPS and related change in book value for Q2 2013 to exclude certain one-time effects of preferred capital redemption and issuance transactions totaling $(0.23) and $(0.28), respectively. These transactions replaced higher-cost preferred equity to the benefit of future earnings. See page 19 for further information and a reconciliation of diluted EPS to this presentation. 

 Authorized $100 Million Stock Repurchase Program  On January 27, 2016 Capstead’s Board of Directors authorized the repurchase of up to $100 million in common stock when such repurchases are deemed appropriate relative to portfolio reinvestment options and liquidity needs. With the significant improvement in the Company’s common stock price subsequent to the authorization of this program, no shares have been repurchased through August 15, 2016.  CMO Multiple of Trailing Book Value  6 

 Market Snapshot(dollars in thousands, except per share amounts)  7  In 2005 and 2006 we issued $100 million face amount of 10-year fixed, 20-year variable-rate, unsecured borrowings in three separate transactions. Utilizing forward-starting 20-year interest rate swap agreements, we have hedged the average cost of this capital down to a fixed cost of 7.77% by the fall of 2016, when the last of the three offerings begins paying variable. Unsecured borrowings are presented net of deferred issuance costs.As of June 30, 2016. 

 Capstead’s Appropriate Use of Leverage  8  Portfolio and Portfolio Leverage  In our view, borrowing at current levels represents an appropriate use of leverage for a short-duration, agency-guaranteed ARM securities portfolio in today’s market conditions.   Long-term Investment Capital 

 Capstead’s Proven Short-Duration Investment Strategy  9  As of June 30, 2016  We finance our agency-guaranteed residential ARM securities primarily with 30- to 90-day secured borrowings augmented with relatively low-cost two-year interest rate swap agreements and longer-dated secured borrowings and interest rate swap agreements when available at attractive levels.  Residential ARM Securities Portfolio  Secured Borrowings & Swap Notional Amounts(by quarter of borrowing maturities / contract expirations)  Total: $13.72 Billion (cost basis)  Our portfolio of agency-guaranteed ARM securities have little, if any, credit risk and are either currently resetting to more current rates at least annually or will begin doing so in five years or less. Our Current-Reset ARMs reset in rate in less than 18 months and our Longer-to-Reset ARMs reset in less than five years. With an asset duration* of approximately 10½ months at quarter-end, the value of our portfolio is naturally less exposed to changes in interest rates than portfolios containing longer duration ARM or fixed-rate securities. This relative stability affords us more flexibility in managing through periods of market stress.We have long-term relationships with a variety of domestic and foreign lending counterparties. At quarter-end we had borrowings outstanding with 23 counterparties, including $750 million in FHLB advances. In response to a regulator-induced moratorium on FHLB advances and membership, we anticipate migrating remaining FHLB balances back to our repo counter-parties by November 2016. We routinely borrow for 30 to 90 days and extend the duration of our borrowings primarily using relatively low-cost two-year pay-fixed interest rate swap agreements. When available at attractive levels, we also enter into longer-dated secured borrowings and interest rate swap agreements. Together with portfolio-related swaps, our secured borrowings had a duration of approximately 8¾ months at quarter-end, resulting in a net duration gap of approximately 1¾ months.  Longer-to-ResetARMs$5.88 Billion(cost basis)  Current-ResetARMs$7.84 Billion(cost basis)      * Duration is a common measure of market price sensitivity to interest rate movements. A shorter duration generally indicates less interest rate risk. 

 Financing Spread AnalysisAs of June 30, 2016 (unaudited)  10  Cash yields on our portfolio of residential ARM securities began increasing during 2015 (after years of declines) primarily due to increases in the underlying indices (principally 12-month LIBOR, six-month LIBOR and one-year CMT).Mortgage prepayment levels directly impact our financing spreads because purchased investment premiums are amortized to earnings as portfolio yield adjustments. Mortgage prepayments are impacted by housing market conditions, including prevailing mortgage interest rates, as well as seasonal factors, in particular the summer home selling season.Unhedged borrowing rates increased in 2016 largely attributable to the Federal Reserve’s December 2015 25 basis point increase in the Fed Funds Rate. Hedged borrowing rates have trended higher as older, lower-rate swaps were replaced at higher rates.  

 Agency Mortgage Prepayment Speeds versus Capstead Prepayment Speeds  11  Published Agency Prepayment Speeds vs. CMO Prepayment Speeds (in CPR)  Mortgage prepayment levels are heavily influenced by the availability of mortgage financing with attractive terms and the overall health of the housing markets, as well as routine seasonal factors. Mortgage interest rates available in the market have followed U.S. Treasury yields lower in 2016 allowing more homeowners opportunities to refinance. As a consequence, mortgage prepayment levels were noticeably higher in the second quarter and look to be higher still in the third quarter before the current refinancing wave can be expected to begin dissipating due to seasonality and portfolio “burnout.”  

 Changes in Key Indices Underlying Capstead’s Residential ARM Securities Portfolio  12  All three of the primary indices underlying our residential ARM securities portfolio increased in 2015, particularly during the latter half of the year in anticipation of Federal Reserve actions to increase short-term interest rates. Six- and 12-month LIBOR increased only modestly while one-year CMT declined during the six months ended June 30, 2016. All three indices increased considerably after quarter-end. 

 * 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 June 30, 2016. 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 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 indexes and net margins in effect, as of June 30, 2016. 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 June 30, 2016.   Key Elements of Capstead’s ARM PortfolioAs of June 30, 2016 (dollars in thousands, unaudited)  13  NOTE: Excludes $3 million legacy portfolio of fixed-rate investments.  The quarter-end Net WAC* on our current-reset ARMs increased 11 basis points since year-end primarily reflecting increases in the underlying six- and 12-month indices over the past 12 months. These indices have turned sharply higher since quarter-end, as illustrated on the previous page. With these higher rates, ARM loans underlying the current-reset component of our portfolio can be expected to continue increasing in coupon in the coming quarters. 

 Capstead’s Stockholder Friendly Structure   14  Expressed on an annualized basis as a percentage of average long-term investment capital.2016 results include $655,000 related to finalizing 2015 performance-based short-term incentive compensation program results in March of 2016.  Capstead is a leader among our mortgage REIT peers in terms of operating cost efficiency.We are internally-managed with lower operating costs than our mortgage REIT peers. Our executives’ pay structure is variable through compensation elements that focus on “pay for performance” as opposed to fees paid to an external manager that are based solely on capital under management. Additionally, our board of directors and our senior executives hold a significant amount of Capstead stock.As a result, we are incented to grow the Company by raising capital only when it is accretive to book value and earnings rather than for the purpose of increasing compensation or external management fees. Conversely, we are also not conflicted regarding whether or not to repurchase shares when appropriate.

 Capstead’s Second Quarter 2016 Highlights  Generated earnings of $21.6 million or $0.19 per diluted common sharePaid common dividend of $0.23 per common shareBook value decreased 0.4%, or $0.04, to $11.21 per common shareYields on residential mortgage investments decreased 18 basis points to 1.54% while rates on related secured borrowings increased two basis points to 0.84%Total financing spreads decreased 18 basis points to 0.64% while financing spreads on residential mortgage investments, a non-GAAP financial measure, decreased 20 basis points to 0.70%Agency-guaranteed ARM portfolio and leverage ended the quarter at $13.90 billion and 9.28 times long-term investment capital, respectively Select comments from our July 27, 2016 earnings press release:Our second quarter earnings were negatively impacted by higher mortgage prepayment levels due to higher refinancing activity as well as seasonal factors. This contributed to $7.0 million in higher investment premium amortization, more than offsetting the benefits of increasing cash yields. Given the current interest rate environment, we expect further increases in investment premium amortization to weigh on our third quarter results before this refinancing wave begins to dissipate.Cash yields benefited from higher coupon interest rate resets as mortgage loans underlying our portfolio of agency-guaranteed residential ARM securities reset to higher rates based on higher prevailing six- and 12-month interest rate indices. We anticipate additional improvements in cash yields in the coming quarters in this rate environment. Regarding borrowing rates, the funding markets remain healthy for financing agency-guaranteed residential mortgage securities leading to expectations for relatively stable borrowing rates given low market expectations for future increases in the Federal Funds Rate.We remain confident in and focused on our investment strategy of managing a leveraged portfolio of agency-guaranteed residential ARM securities that can produce attractive risk-adjusted returns over the long term while reducing, but not eliminating, sensitivity to changes in interest rates.  16

 Non-GAAP Financial MeasuresAs of June 30, 2016 (unaudited)  20  Financing spreads on residential mortgage investments, a non-GAAP financial measure, differs from total financing spreads, an all-inclusive GAAP measure, that is based on all interest-earning assets and all interest-paying liabilities. We believe presenting financing spreads on residential mortgage investments provides useful information for evaluating the performance of the Company’s portfolio.Core earnings per diluted common share is a non-GAAP financial measure that differs from the related GAAP measure of net income per diluted common share by excluding certain one-time effects of second quarter 2013 transactions to redeem then-outstanding high-cost convertible preferred capital and issue our 7.50% Series E preferred shares. We believe presenting this metric on a core earnings basis provides useful, comparative information for evaluating the Company’s performance.
