- Plan triggers ownership threshold at 4.99%; effective Aug 14, 2025; expires Aug 14, 2026 unless extended.
- Adoption satisfies covenant in Note Purchase Agreement with Rubric Capital Management dated Aug 8, 2025.
- Rights plan deters any single investor or group from crossing 4.99% beneficial ownership without Board approval.
