Yeung William

Yeung William, Chief Legal Officer, has demonstrated a clear pattern of selling activity in shares of Energy Recovery, Inc. (ERII) over the past year, as evidenced by SEC Form 4 filings. Between September 2025 and February 2026, Yeung executed 13 sell transactions, totaling approximately $1,426,829 in value, with no recent purchases recorded. Notably, the largest single sale occurred on September 11, 2025, when Yeung disposed of shares worth $486,868.54, followed by another significant sale on September 18, 2025, valued at $233,139.04. These transactions were accompanied by smaller, consistent sales throughout October 2025 and into early 2026, including a $105,793.05 sale on January 28, 2026, and a $12,985.10 sale on February 5, 2026. Additionally, Yeung engaged in multiple transactions coded as "M," likely representing the exercise of derivative securities such as options, which were often paired with sales on the same dates. The data reveals a pronounced selling bias, with Yeung’s total sell value more than doubling the total buy value of $604,766.17, which occurred earlier in the timeline. This activity suggests a strategic reduction in Yeung’s holdings of ERII shares over time. While the filings do not provide context for these transactions, the consistency and volume of sales indicate a deliberate approach to managing equity positions in the company. The focus on ERII, the sole company involved in these trades, underscores Yeung’s concentrated activity in this security during the reported period.
