    NEW YORK--(BUSINESS WIRE)--Oct. 16, 2007--Jefferies Group, Inc.
(NYSE: JEF) today announced financial results for the third quarter
ended September 30, 2007.

    Highlights for the third quarter ended September 30, 2007:

    --  Net revenues were down 2% to $334.4 million, versus $340.6
        million for the third quarter of 2006.

    --  Net earnings were down 16% to $38.8 million, compared to $45.9
        million for the third quarter of 2006.

    --  Earnings per share (diluted) were down 19% to $0.26, compared
        to $0.32 for the third quarter of 2006.

    --  Investment banking revenues were up 31% to $189.8 million,
        compared to $144.8 million for the third quarter of 2006.

    "We are pleased that the challenging third quarter is behind us,"
commented Richard B. Handler, Chairman and Chief Executive Officer of
Jefferies. "The fact that our net revenues and net earnings for the
quarter were each merely $7 million below last year's comparable
period results is a testament to the hard work of our 2,513 employee
partners, our diversified business model, our conservative balance
sheet and the loyalty of our client base."

    Brian P. Friedman, Executive Committee Chairman, added, "Our
investment banking revenues totaled $190 million, which represents our
second best quarterly total ever. We are pleased with these results
given the difficult market environment which made the normally slow
summer months even more challenging."
