PSEG Initiates 2024 Non-GAAP Operating Earnings Guidance

(NEWARK, N.J. – December 19, 2023) – Public Service Enterprise Group (NYSE: PEG) has initiated 2024 non-GAAP Operating Earnings guidance in the range of $3.60 to $3.70 per share. The midpoint of the Company’s 2024 guidance represents earnings growth of approximately 6% from the midpoint of its 2023 non-GAAP Operating Earnings guidance of $3.40 to $3.50 per share.

“Consistent with an improved business mix and a platform for predictable growth, PSEG has introduced 2024 non-GAAP Operating Earnings guidance that follows our existing long-term outlook for compound annual earnings growth in the range of 5% to 7% for 2023 through 2027,” said Ralph LaRossa, PSEG’s chair, president, and CEO.

“Guidance for 2024 is presented on a consolidated basis and reflects the estimated earnings contributions of both Public Service Electric and Gas and PSEG Power & Other. PSEG continues to execute on our plan to increase the predictability of our business, which is built on a foundation of operational excellence, disciplined investment, and the continuation of financial strength,” LaRossa added.

Non-GAAP Financial Measures

Management uses non-GAAP Operating Earnings in its internal analysis, and in communications with investors and analysts, as a consistent measure for comparing PSEG’s financial performance to previous financial results. Non-GAAP Operating Earnings exclude the impact of gains (losses) associated with the Nuclear Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting and material one-time items. The presentation of non-GAAP Operating Earnings is intended to complement, and should not be considered an alternative to the presentation of Net Income/(Loss), which is an indicator of financial performance determined in accordance with GAAP. In addition, non-GAAP Operating Earnings as presented in this release may not be comparable to similarly titled measures used by other companies. Due to the forward-looking nature of non-GAAP Operating Earnings guidance, PSEG is unable to reconcile this non-GAAP financial measure to the most directly comparable GAAP financial measure because comparable GAAP measures are not reasonably accessible or reliable due to the inherent difficulty in forecasting and quantifying measures that would be required for such reconciliation. Namely, we are not able to reliably project without unreasonable effort MTM and NDT gains (losses), for future periods due to market volatility. These items are uncertain, depend on various factors, and may have a material impact on our future GAAP results.
