Board & Oversight

Board composition shifted materially at the May 2025 AGM: six directors who were also operating-group executives (Jeff Bender – Harris; Robin Van Poelje – Topicus; Lori O'Neill; Dexter Salna; Susan Gayner; Barry Symons) did not stand for re-election. Post-2026 AGM, 7 of 9 directors are independent, versus a board with more executive-directors previously. Per 2026 Circular, Schedule A
Miller himself rolled off the CSI board at the May 2025 AGM, then was reappointed December 9, 2025, after being named President — a temporary gap tied to the leadership transition, not an unexplained departure. Per 2026 Circular, Schedule A attendance table
Independent directors show independent wealth/status rather than fee-dependence: a law-firm senior advisor and multi-board director (Kennedy), a professor and Markel Group director (Cunningham), an EdgePoint partner (Pastor), a PE/VC managing partner (Parr), and a former CEO who sold her company (Schultz). Board fees are modest ($60,000–$120,000/year) and the after-tax portion must be used to buy CSI shares. No captured-behaviour patterns identified.

Reasons to Own

Voluntarily waived 100% of salary and bonus as President effective January 1, 2026 — zero cash compensation, continuing his predecessor's 15-year precedent of unpaid top leadership.
Company-wide stock-based compensation is $0 (0% of revenue); CSI grants no options or RSUs to any executive.
Incentive bonus structure mandatorily converts 75% of after-tax bonus into CSI shares bought on the open market — pay is mechanically tied to being a shareholder, with no dilution to existing holders.
Personal stake of 254,533 CSI shares (~C$725M, ~1.2% of shares out) built over 30 years, plus large positions in CSI affiliates Topicus.com and Lumine Group — this is his life's work, not a side bet.
Net buyer of CSI shares as recently as September 2025.
No family office or VC vehicle; outside board seats are either CSI affiliates or small/non-profit organizations, leaving little competing claim on his attention.
Named Executive Officer compensation rose only 39% from 2020–2025 versus 106% total shareholder return over the same period — pay grew slower than the value delivered to shareholders.

Reasons Not to Own

Under one year of tenure specifically in the President role (since September 25, 2025), following the abrupt, health-related resignation of long-time founder-leader Mark Leonard — limited public track record in the top job itself, notwithstanding 30 years at the company.
Holds two outside board seats unrelated to CSI's core software business (ventureLAB, VoxCell BioInnovation) — a modest, non-compensated draw on attention, not flagged as a material conflict.
