Strategy

Berkshire Equity Commitment

• Berkshire provides MEHC with a $3.5 billion equity
commitment from ‘AAA’ rated parent

– Access to capital even in times of utility sector and general market stress;

No other utility has this quality of explicit financial support

– Commitment can only be drawn for two purposes:

• Paying MEHC parent debt when due

• Funding the general corporate purposes and capital requirements of
MEHC’s regulated subsidiaries

• Future M&A activity will be funded separate from this
equity commitment

MEHC’s diversity coupled with its 100% reinvestment of free cash flow
and access to equity capital from Berkshire under any market condition
clearly differentiates the quality of MEHC’s credit from its peers

certain generating assets at predetermined prices for up to $350 million of cash

– MidAmerican will finance the $4.7 billion transaction through the issuance of:

• Approximately $2.7 billion of its common stock to Berkshire and potentially to its other
existing shareholders

• $2.0 billion in 11% Trust Preferred securities to Berkshire
