Adagene (ADAG) CFO Tam Man Kin Buys 2,000 ADS

What Happened
Tam Man Kin, Chief Financial Officer of Adagene Inc. (ADAG), made an open-market purchase of 2,000 American Depositary Shares (ADSs) on 2026-09-23 at $3.00 per ADS, for a total cash outlay of $6,000. This was a purchase (code P), which is a buying transaction rather than a sale.

Key Details

• Transaction date and price: 9/23/2026 — 2,000 ADSs at $3.00 each; total = $6,000.
• Filing date: Form 4 filed 2026-09-25 (timely; within the typical 2-business-day window).
• Shares owned after transaction: the filing does not state a consolidated total ownership amount after this trade.
• Footnote F1: The report includes (i) the 2,000 ADSs bought on 9/23/2026 and (ii) an RSU vesting on 7/23/2026 that corresponded to 10,000 ADSs (equal to 12,500 ordinary shares).
• Footnote F2: The RSU grant (under the 2021 Performance Incentive Plan, granted July 2024) has remaining vesting tranches equivalent to 10,000 ADSs (12,500 ordinary shares) vesting on 7/23/2027 and 7/23/2028.
• Transaction type: Open-market purchase (P). Not reported as a gift, exercise, or tax withholding.

Context

• ADS note: Footnotes indicate 10,000 ADSs = 12,500 ordinary shares, i.e., 1 ADS = 1.25 ordinary shares. ADSs are U.S.-traded receipts for foreign ordinary shares.
• RSU background: The transaction report references previously vested and remaining RSUs granted under Adagene’s 2021 Performance Incentive Plan (grant made July 2024). RSU vesting is a separate compensation event and is listed for transparency.
• Interpretation for investors: Insider purchases can be viewed as a mild positive signal since the CFO bought shares, but this was a small open-market buy ($6k). The filing is factual and timely; it does not reveal the insider’s motives.
