California Water Service Group VP Elissa Ouyang Stock Transactions

This SEC Form 4 filing reports two stock transactions by Elissa Y. Ouyang, Vice President of Facilities, Fleet, Procurement & IT at California Water Service Group. On June 4, 2026, Ouyang disposed of 67 shares of common stock at $45.24 per share through tax withholding related to the vesting of a Restricted Stock Award granted on March 4, 2025. The following day, June 5, 2026, she disposed of an additional 66 shares at $45.82 per share, also through tax withholding for a Restricted Stock Award vesting from June 5, 2024. Following these transactions, Ouyang's total holdings decreased to 15,005.041 shares after the first transaction and further to 14,939.041 shares after the second. The filing indicates these were mandatory tax withholding events rather than voluntary sales, with the shares being surrendered directly to the issuer to satisfy tax obligations arising from restricted stock vesting.
