Item 9. Regulation FD Disclosure - --------------------------------- On October 22, 2003, PSEG announced unaudited financial results for the quarter ended September 30, 2003. A copy of the press release of earnings dated October 22, 2003 is furnished as Exhibit 99 to this Form 8-K. The information contained in Item 9 of this report is being furnished pursuant to Item 12 under Item 9 as directed by the U.S. Securities and Exchange Commission. To supplement PSEG's consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), the Company uses non-GAAP measures of pro forma operating income and pro forma operating income per share which does not include losses relating to the impairment and operations of Energy Holdings' Argentine investments in 2002.

PSEG urges shareholders to carefully review the GAAP financial information included as part of the PSEG's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and quarterly press releases of earnings. 2 <Page> SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
