The Meeting will be held at the offices of Burnet, Duckworth & Palmer LLP located at 2400, 525 – 8th Avenue SW, Calgary, Alberta T2P 1G1 on June 15, 2026 at 9:00 a.m. (Calgary time).

The recommendations from the independent proxy advisory firms, including ISS, follow the unanimous recommendation of Blackline's special committee of independent directors (the "Special Committee") and its board of directors (with all interested directors abstaining) that shareholders vote FOR the Transaction.

Jason Cohenour, Chair of the Special Committee commented:

"We are pleased that the leading independent proxy advisory firms have recognized the benefits and merits of the Transaction for Blackline shareholders and have recommended that shareholders vote in favour of the Transaction. These recommendations support the conclusions and recommendations of the Special Committee, who oversaw a robust strategic review and sales process. The Transaction provides shareholders with the opportunity to realize immediate and certain value in cash for their investment at a significant premium to recent trading levels and potential additional value through the CVRs."
