Antony Prabhu 4

What Happened

• Antony Prabhu, CFO of StoneBridge Acquisition II Corporation (APAC), is reporting an award-related transaction: on February 5, 2026 the issuer approved an equity grant of 100,000 Class B Ordinary Shares. No cash price is listed (N/A). The Class B shares automatically convert into Class A Ordinary Shares on a one-for-one basis upon the issuer’s initial business combination and have no expiration date.
• The reported shares were transferred by the issuer’s sponsor, StoneBridge Acquisition Sponsor II LLC, to four independent members of the issuer’s board for their board and committee service. The reporting person did not receive shares directly in his individual capacity.

Key Details

• Transaction date: February 5, 2026. Form filed: February 6, 2026 (timely).
• Transaction type/code: A = Award/Grant (derivative instrument — Class B Ordinary Shares). Price: N/A; total reported shares: 100,000.
• Shares of record: The 100,000 shares were held of record by the Sponsor. The reporting person is a member of BP SPAC Sponsor II LLC, the sole managing member of the Sponsor, and thus may be deemed to share beneficial ownership of shares held by the Sponsor.
• Disclaimer: The reporting person disclaims beneficial ownership of the reported shares except to the extent of any pecuniary interest he may have.
• Filing timeliness: Filed one day after the transaction date; not indicated as late.

Context

• These Class B share grants are a board compensation action recorded by the sponsor and will convert to Class A on a 1:1 basis at the time of a qualifying business combination. This is not a typical insider buy or sell by the individual filing—it's a sponsor-level grant to independent directors and does not necessarily reflect the reporting person’s personal trading intent.
