Nasdaq: AGNC -30 -20 -10 0 10 20 30 40 50 60 Jun-10 Dec-10 Jun-11 Dec-11 Jun-12 Dec-12 2013 Agency MBS Spread Performance 6 Agency MBS spreads relative to swaps have widened significantly since the announcement of QE3 despite massive FED purchases totaling approximately $625 billion (1). We believe this result can be attributed to greater monthly MBS issuance volume, foreign and domestic investor sales, convexity hedging from levered investors and general concerns about higher interest rates that have kept potential buyers on the sidelines 30 Year Current Coupon Spread to LIBOR After Adjusting for Option Costs (2) ♦ Agency MBS spreads have widened quarter-to-date, causing a decline in our estimate of book value for the quarter similar to what we experienced in Q1 (3) ♦ Wider MBS spreads, although negative for current period book value, should provide more attractive investment opportunities going forward 2.

Not subject to normal quarterly closing / review process. As a result, actual performance could deviate materially. Jun-13 1. Dealer estimates September 2012 – May 2013

Nasdaq: AGNC AGNC’s Approach to the Current Environment ♦ Our leverage has remained within a reasonable band during the quarter despite declines in book value  Current aggregate leverage (TBAs + on balance sheet assets) is not significantly different from our first quarter average of 8.2x and has not been significantly higher at any point during the quarter We believe we are well positioned to increase leverage in the future if we feel the risk/return tradeoffs become more compelling ♦ We have also taken some actions to position our asset portfolio for the current environment such as reducing exposure to both lower coupon 30-year fixed-rate MBS and higher pay-up 4% coupon specified pools (1)  We have increased the duration of our hedges consistently as interest rates have moved higher during the second quarter  These actions will likely create some reduction in our earnings potential and our book value upside if rates fall and/or MBS spreads tighten materially; however, we believe they give us greater flexibility to respond to future market volatility 7 Given the recent significant volatility in global fixed-income markets and in MBS, we have continued to actively and consistently manage both our assets and our hedges during the quarter 1. As of June 7, 2013

Nasdaq: AGNC Managing Mortgage Extension Risk (1) 8 Our hedges, coupled with ongoing portfolio rebalancing actions, have allowed us to maintain a conservative interest rate risk profile despite the rise in interest rates (2) 1. Extension risk is the risk that the duration of a mortgage security increases in a rising rate environment. 2. As of June 7, 2013 3. Duration of liabilities, hedges and swaptions expressed relative to asset units The estimated duration gap sensitivity included in the table above is derived from models that are dependent on inputs and assumptions provided by third parties as well as by our investment team and, accordingly, actual results could differ materially from these estimates. The sensitivity analysis also assumes an instantaneous change in interest rates and, consequently, does not include the potential impact of ongoing portfolio rebalancing actions Duration Gap Sensitivity (years) as of 4/30/2013 Position Rates Up Rates Up 4/30/2013 100 Bps 200 Bps Total Mortgage Assets 3.6 5.7 6.6 Liabilities & Hedges (3) -3.8 -4.5 -4.8 Net Duration Gap -0.2 1.2 1.8 Duration Gap Sensitivity (years) as of 6/7/2013 Position Rates Up Rates Up 6/7/2013 100 Bps 200 Bps Total Mortgage Assets 5.2 6.3 6.6 Liabilities & Hedges (3) -4.5 -5.1 -5.3 Net Duration Gap 0.7 1.2 1.3

Nasdaq: AGNC 9 Significant Capacity to Withstand Market Disruptions We believe we have the capacity to withstand significant market disruptions given that we have significant equity available to absorb potential reductions to book value, higher margin requirements, or other unexpected cash needs ♦ Approximate equity uses based on positions as of March 31, 2013, including 5.7x on-balance sheet leverage and 2.4x off-balance sheet leverage and a 12% CPR assumption ♦ Repo haircuts generally cannot be changed by providers during the funding term ♦ TBA positions have favorable margin requirements relative to assets that are financed on-balance sheet through repo transactions ♦ Excess equity should be available to support underperformance of mortgages over a wide range of leverage scenarios 8% 7% 8% 29% 48% 0% 20% 40% 60% 80% 100% Available Repo Haircuts TBA Margin Prepays Other Sources Under- Performance 6x 7x 8x 9x 10x 1 point (7%) (8%) (9%) (10%) (11%) 2 points (14%) (16%) (18%) (20%) (22%) 3 points (21%) (24%) (27%) (30%) (33%) Hypothetical Loss in Equity due to Mortgage Underperformance at Various Leverage Levels (1) Approximate Equity Uses 1. Represents net percentage decline in assets versus hedges. This table is a simple math calculation multiplying the underperformance impact by leverage plus equity and importantly, it does not assume or attempt to estimate the impact of various external factors on equity. Thus, this table should be viewed for illustrative purposes only

Nasdaq: AGNC 10 Outlook for MBS We believe the intermediate term outlook (next 3-12 months) is positive for Agency MBS given current valuations and favorable supply and demand dynamics even with gradual FED tapering ♦ It is reasonable to expect significant near term volatility in both interest rates and MBS spreads ♦ MBS spreads have widened to near long-term historical averages despite the ongoing purchases and massive holdings of Agency MBS by the FED ♦ Even if the FED begins tapering QE3 in September and completes the program by the end of Q1 2014 they will likely still purchase between $350 and $450 billion in additional MBS over the next 10 months (1) ♦ In conclusion, we believe the intermediate term landscape for Agency MBS should be favorable  Absent a significant decline in mortgage rates, gross MBS issuance will likely drop to less than $100 billion per month by late Q3 (1), compared to an average of more than $150 billion per month during Q1 2013 (2)  Money managers and some foreign investors have likely reduced mortgage holdings post QE3 and more attractive yields/spreads should encourage banks and other domestic demand for mortgages  Levered investor and servicer positions should be more balanced given recent price volatility as a meaningful portion of convexity hedging has probably already occurred  Lower outstanding tradable supply of Agency MBS can be expected given FED holdings of nearly $1.5 trillion by year end 1. Based on internal estimates 2. Based on Dealer estimate
