As noted in prior market status notices, April 27, 2026 was the first day national securities exchanges were scheduled to publish odd lot information to the SIPs. Due to a defect in the software release supporting this change, NYSE Group Equities Exchanges (the "NYSE Exchanges") published incorrect odd lot information on April 27th for certain symbols (the "Impacted Symbols"), suspended odd lot publication for April 28th, and then resumed odd lot publication to the SIPs on April 29th without further issue after the defect was fixed. A list of the Impacted Symbols, per NYSE Exchange, is attached.
