Shareholders of Quarterhill Inc.
Five shareholders are currently on record for Quarterhill Inc., reflecting the securities register maintained under sections 20 and 50 of the Canada Business Corporations Act rather than a public filing. The largest of these is DFA International Small Cap Value Portfolio, holding 26.9% — the largest recorded stake — followed by DFA International Core Equity Portfolio at 14.7%; the remaining 3 shareholders shown hold smaller stakes.
