Documented cause
Acacia Communications was not a failure in the traditional sense but its independent existence ended in a forced Cisco acquisition for $4.5B after a near-collapse. Cisco originally agreed to acquire Acacia in 2019 for $2.6B, then attempted to terminate the deal in 2020 citing material adverse change during COVID. Acacia sued and won, forcing Cisco to close the acquisition at $115/share in March 2021, eliminating the standalone photonic chip company.
Lesson
“Deep tech acquisition deals need ironclad MAC clauses; walk-away attempts destroy team morale regardless of legal outcome.”
