“Knight just reported its best quarterly earnings in more than two years, coming in well above expectations during what are typically the slowest three months of the year for our industry,” said Thomas M. Joyce, Chief Executive Officer and President of Knight Trading Group. “Each of Knight’s businesses operated on a profitable basis for the second consecutive quarter. Higher volume, intra-day volatility and increases in dollar value traded during the quarter made for a positive trading environment for Knight as well as attracted more investors to the market. Finally, Knight made further progress adding new clients while garnering more business from its current roster.”

Domestic Businesses

The company’s domestic businesses earned net income of $23.4 million, led by a strong performance in the cash equity market-making business. For the third quarter of 2002, the net loss from all domestic businesses was $1.0 million.

“Knight continues to introduce fundamental change to our business – for instance, our recent agreement to purchase Donaldson & Co., a leading soft dollar and commission recapture firm,” Mr. Joyce said. “These programs are an integral part of the investment process, and we believe the addition to Knight’s institutional offering is an extension of the company’s strategy to focus all efforts around client needs. Knight always seeks growth opportunities through appropriate investments in new products and services, like soft dollar programs, and in the select hiring of key personnel. To offset the short-term rise in expenses resulting from these initiatives, Knight will continue its internal efforts to drive efficiencies across all businesses.”

The company’s Asset Management business segment generated $13.0 million in asset management fees during the third quarter of 2003, up from $6.1 million in the same period a year ago, reflecting better returns. The asset management business had approximately $1.4 billion and $1.2 billion of assets under management at September 30, 2003 and 2002, respectively. In addition, the company earned $5.3 million during the third quarter of 2003 on its investment in the Deephaven funds.

The company had 870 employees in the U.S. at the end of the third quarter, down from 967 at the end of 2002 and down from 945 at the end of September 2002.

International Businesses

For the third quarter of 2003 (and for the second consecutive quarter), continuing international operations were slightly profitable. For the third quarter of 2002, the net loss from continuing international operations was $2.4 million.

As of September 30, 2003, Knight had 40 employees in Europe. The company had 63 employees in all international operations at the end of 2002, compared to 89 international employees at the end of September 2002.

“While we have two consecutive solid quarters under our belt, Knight has yet to pass the test under unfavorable market conditions,” Mr. Joyce said. “Recent questions around the broad market infrastructure and oversight could make for a potentially choppy trading environment in the fourth quarter. And, while recent economic indicators have been positive, there remains a possibility for investors to become unsettled again in this atmosphere of change. With directionality for the coming months unclear, Knight continues its search to uncover maximum trade efficiency across the breadth and depth of the marketplace – a necessity for both Knight and for our clients, who themselves face challenge and opportunity in the wake of the revived market structure debate.”

Liquidity and Stock Repurchase Plan

The company had $765.4 million in stockholders’ equity as of September 30, 2003, equivalent to a book value of $6.74 per share. As of September 30, 2003, the company had $276.5 million in cash and cash equivalents and a $192.1 million investment in funds managed by its Deephaven subsidiary.

At its May 12, 2003 meeting, the Board of Directors authorized an additional increase in the size of the repurchase program from $70 million to $95 million. During the third quarter of 2003, the company repurchased 522,900 shares for $5.1 million. To date, the company has repurchased 14,290,200 shares for $74.3 million under the $95 million stock repurchase program. The company cautions that there are no assurances that any further repurchases may actually occur.
