Remarks: This Form 4 is the second of two Forms 4 being filed by the Reporting Person relating to transactions that occurred on June 25, 2026 and June 26, 2026 (the "Transaction Dates"). Because there are more than 30 rows associated with the Reporting Person's transactions that occurred on the Transaction Dates, and EDGAR will not allow for the entry of more than 30 rows on a single Form 4, this second Form 4 is being filed to report the transactions that were not included on the first Form 4. The two Forms 4 filed by the Reporting Person on the date hereof should be read together as one consolidated filing.
