Sung Miyun 4

What Happened
Sung Miyun, Chief Legal Officer & Secretary of Chimera Investment Corporation (CIM), was granted 31,164 restricted stock units (RSUs) on January 20, 2026. The award is recorded at $0.00 per unit (total $0) and is an equity grant (transaction code A) rather than a purchase or sale.

Key Details

• Transaction date: 2026-01-20; Form 4 filed 2026-01-21 (appears timely).
• Grant: 31,164 RSUs @ $0.00 (Acquired = $0).
• Vesting: RSUs vest one-third per year on December 31 of 2026, 2027 and 2028 and will be settled 100% in Chimera common stock (see F1).
• Economic equivalence: Each RSU equals one share of common stock (F2). Dividend equivalent rights on RSUs are included in the reporting person’s common stock holding balance and are treated as equivalent to shares (F3).
• The reporting person states they do not intend to separately report each vesting or delivery of shares.

Context
RSU grants are common compensation and retention tools for executives; they are not open-market purchases and therefore do not directly signal a personal cash investment. These RSUs will convert to Chimera common shares as they vest over the next three years, at which point tax withholding or other delivery mechanics may apply (not detailed in this filing).
