CEO Sun Qing Bill buys 26,250 shares of YCY at $10.00 for $262,500 on 2025-10-09, holdings rise to 3.24M shares

Sun Qing Bill, Chief Executive Officer of AA Mission Acquisition Corp. II, purchased 26,250 shares at $10.00 on 2025-10-09, increasing his total holdings from 3.21M to 3.24M shares. This represents the second open-market purchase at YCY within one week, following a prior buy on 2025-10-02; outcomes from that earlier purchase are not yet measurable. Across his broader trading history (3 prior buys at other tickers), the insider's average 90-day return has been +0.5% with a 100% win rate, though this cross-ticker track record does not necessarily predict outcomes at YCY. The pattern of repeat buying at the same ticker in consecutive weeks, combined with a modest increase in aggregate holdings (+0.8%), warrants attention to whether these purchases reflect an operational trigger or market opportunity assessment.

CEO Sun Qing Bill purchases 334,000 shares of YCY at $10.00 for $3,340,000; holdings increase to 3.21M shares (+11.6%)

CEO Sun Qing Bill acquired 334,000 shares at $10.00 on 2025-10-02, deploying $3,340,000 in capital and expanding his stake from 2.88M shares to 3.21M shares (+11.6% increase). This represents a material personal investment by the chief executive officer in YCY at the at-the-money acquisition price ($10.00). Historically, across all tickers, this insider's 2 prior buys generated a +0.5% average 90-day return with a 100% win rate, though this cross-ticker track record may not reflect performance specific to YCY. The magnitude of the purchase—over $3.3 million in a single transaction at a round-number price—warrants scrutiny into the company's current position and the timing of the CEO's decision to increase his personal exposure at this valuation.

CEO Sun Qing Bill purchases 90,000 shares of AAM at $10.00 for $900,000.00; second buy in under 5 weeks

Sun Qing Bill, CEO of AA Mission Acquisition Corp., purchased 90,000 shares at $10.00 on 2024-09-05, bringing his post-transaction holdings to 9,474,000 shares. This represents his second open-market purchase at AAM in less than five weeks, following an earlier buy on 2024-08-02. The transaction increases his stake by 1.0% relative to pre-transaction holdings. Without measurable 90-day outcomes from prior trades at this ticker and limited cross-ticker history (1 prior buy total), there is insufficient pattern data to characterize the timing quality of his purchases.

CEO Sun Qing Bill purchases 759,000 shares of AAM at $10.00 for $7,590,000.00

Sun Qing Bill, CEO of AA Mission Acquisition Corp., acquired 759,000 shares at $10.00 on 2024-08-02, representing a $7,590,000.00 investment that increased his holdings from 8,625,000 shares to 9,384,000 shares—an 8.8% addition to his pre-transaction position. As the company's chief executive, an executive purchase of this magnitude demonstrates material capital commitment from the individual responsible for company direction. The transaction occurred at the $10.00 typical price point associated with SPAC (special purpose acquisition company) structures, which AAM appears to be based on its corporate designation. Without access to contemporaneous market conditions, earnings, or prior track record at this ticker, the decision's context relative to company value or recent announcements cannot be assessed from the filing alone.
