generally, we and our subsidiaries may not be able to maintain our current credit ratings. Ratings downgrades by a rating agency could have a significant and immediate impact on our funding and liquidity through reduced funding capacity. A reduction
in our or our subsidiaries’ credit ratings could also increase our borrowing costs and limit access to the capital markets.

S-10

Downgrades in the credit or financial strength ratings assigned to the counterparties with
whom we transact could create the perception that our financial condition will be adversely impacted as a result of potential future defaults by such counterparties. Additionally, we could be adversely affected by a general, negative perception of
financial institutions caused by the downgrade of other financial institutions. Accordingly, ratings downgrades for our commercial counterparties or other financial institutions could affect the market price of our stock and could limit our access
to or increase our cost of capital.

Risk Factors Related to Interest Rate Reset

The amount of interest payable on the Notes will reset on September 11, 2030 and the subsequent interest rate may be lower than the interest rate for the Initial Fixed Rate Period.

During the Initial Fixed Rate Period, the Notes will bear interest at an initial
rate of 5.784% per annum. Thereafter, the Notes will bear interest at an annual rate equal to the U.S. Treasury Rate for a five-year maturity as of the Reset Determination Date plus 212.5 basis points, subject to the provisions under
“Description of the Notes—Interest Rate,” which could be less than the interest rate during the Initial Fixed Rate Period. The per annum interest rate that is determined at the Reset Determination Date for the Subsequent Fixed Rate
Period will apply during the entire Subsequent Fixed Rate Period following the Reset Determination Date even if the U.S. Treasury Rate for a five-year maturity increases during that period.

Historical rates are not an indication of future rates.

In the past, the U.S. Treasury Rate for a five-year maturity has experienced significant fluctuations. You should note that historical levels,
fluctuations and trends of the U.S. Treasury Rate for a five-year maturity are not necessarily indicative of future levels. Any historical upward or downward trend in the U.S. Treasury Rate for a five-year maturity is not an indication that the U.S.
Treasury Rate for a five-year maturity is more or less likely to increase or decrease at any time, and you should not take the historical U.S. Treasury Rate for a five-year maturity levels as an indication of future
