MERRILL LYNCH SAYS CREDIT MARKET CONDITIONS
TO ADVERSELY IMPACT THIRD QUARTER 2007 RESULTS

     NEW YORK, October 5 — Merrill Lynch & Co., Inc. (NYSE: MER) today announced that challenging credit market conditions will have an adverse impact on its net earnings for the third quarter. The company expects to report a net loss per diluted share of up to $0.50, resulting from significant negative mark-to-market adjustments to its positions in two specific asset classes: collateralized debt obligations (CDOs) and sub-prime mortgages; and leveraged finance commitments. These mark-to-market adjustments primarily affect Merrill Lynch’s Fixed Income, Currencies & Commodities (FICC) business. The company expects to report revenue growth in excess of 20% over the 2006 third quarter in each of its other major business lines: Equity Markets (excluding the firm’s private equity business), Investment Banking and Global Wealth Management. Merrill Lynch expects to report a solid revenue performance from the rest of its FICC business, considering market conditions, and expects strong performance from its operations outside the U.S., led by the Pacific Rim region.

     “Despite solid underlying performances in most of our businesses in the third quarter, the impact of this difficult market was much more severe in certain of our FICC businesses than we expected earlier in the quarter,” said Stan O’Neal, chairman and chief executive officer of Merrill Lynch. “While market conditions were extremely difficult and the degree of sustained dislocation

unprecedented, we are disappointed in our performance in structured finance and mortgages. We can do a better job in managing this risk, as we have done with other asset classes, including leveraged finance, interest rate and foreign exchange trading, equity trading, principal investments and commodities.”

     Merrill Lynch noted that Senior Vice President David Sobotka, (50), was promoted to the position of global head of FICC earlier in the week. Mr. Sobotka had been head of the group’s global commodities unit since 2004, when Merrill Lynch acquired Entergy-Koch, L.P.’s trading businesses, where he had been president.

     “David Sobotka is a strong leader with a proven track record,” said Mr. O’Neal. “He has gained a reputation as one of our most collaborative senior executives, a strong risk manager and a key contributor to the overall Global Markets & Investment Banking (GMI) franchise. I have every confidence in his ability to lead the entire FICC organization and make an even greater contribution to Merrill Lynch in the coming years.”

     The primary drivers of the FICC net losses in the third quarter were as follows:

	•		Write-downs of an estimated $4.5 billion, net of hedges, related to incremental third quarter market impact on the value of CDOs and sub-prime mortgages. These valuation adjustments reflect in part significant dislocations in the highest-rated tranches of these securities which were affected by an unprecedented move in credit spreads and a lack of market liquidity in these securities, which intensified during the third quarter. During the quarter, the company significantly reduced its overall exposure to these asset classes.
	•		Write-downs of an estimated $967 million on a gross basis, and $463 million net of related underwriting fees, related to all corporate and financial sponsor, non-investment grade lending commitments, regardless of the expected timing of funding or closing. These commitments totaled $31 billion at the end of the third quarter of 2007, a net reduction of 42% from $53 billion at the end of the second quarter. The net losses related to these commitments were limited through aggressive and effective risk management, including disciplined and selective underwriting and exposure reductions through syndication, sales and transaction restructurings.

     “Although the outlook for fourth quarter revenues remains difficult to predict, we continue to see evidence of strong long-term growth trends in each of our global businesses. While it is very early

in the current quarter and despite continued challenges in structured finance, we are beginning to see signs of a return to more normal activity levels in a number of markets. Given our strong core operating performance and solid market, liquidity and capital positions, we are confident in our ability to deliver superior returns to shareholders over the long-term,” Mr. O’Neal concluded.
