Debt Instrument, Covenant Description For both facilities, the margin and facility fee are subject to changes in the Company's credit ratings. In May 2025, Moody’s Ratings affirmed EastGroup’s issuer rating of Baa2 and changed its rating outlook from stable to positive. Given the strength of the Company’s key credit metrics, initial pricing for the credit facilities is based on the BBB+/Baa1 credit ratings level. This favorable pricing level will be retained provided that the Company’s consolidated leverage ratio, as defined in the applicable agreements, remains less than 32.5%  
Sustainability performance component The $625,000,000 facility also includes a sustainability-linked pricing component, pursuant to which the applicable interest rate margin is adjusted if the Company meets a certain sustainability performance target. This sustainability metric is evaluated annually and was achieved for the year ended December 31, 2024, which allowed for an interest rate reduction during the three and six months ended June 30, 2025. The margin was effectively reduced on this unsecured bank credit facility by four basis points, from 77.5 to 73.5 basis points, and the facility fee was reduced from 15 to 14 basis points during the three and six months ended June 30, 2025.
