Passive stake amendment
Actionable Insight • Neutral

The correction of prior overstatements removes any perception of significant passive ownership. The actual stake remains trivial and has no bearing on the stock. Monitor for any future 13D conversion if holdings approach 5%.

Executive Summary

Boston Partners filed an amendment to its Schedule 13G for DoubleDown Interactive, disclosing a passive stake of 0.53% as of September 30, 2026. The filing also corrects prior overstatements: the previously reported 5.40% and 6.66% stakes were errors due to incorrectly comparing ADS holdings to common shares outstanding. The actual stake has increased from 0.27% (March 2026) to 0.33% (June 2026) to 0.53% (September 2026), but remains well below 5% and is immaterial.
