Why it may matterVerify against the original reporting

Progress on construction, secured financing, and anchor tenants reduce execution risk and improve NAV visibility, supporting near-term sentiment. However, the 2029 completion means the stock may only see gradual upside unless further leasing or cost control materializes.
