Key Details

• Filing date: March 27, 2026 (Form 8-K reporting press release).

Why It Matters
This 8-K signals that Instil Bio has publicly reported its most recent quarterly and annual financial performance; investors should review the attached press release (Exhibit 99.1) for revenue, earnings, cash position, and management commentary. The filing itself does not include the line-item financial statements in the 8-K text, so the press release is the primary source for the announced results and any operational updates.
