Insights

Financial Analyst

TL;DR: Reporting persons disclose a material, passive stake of 8.25% in Allegiant, with explicit sole voting and dispositive power figures.

The Schedule 13G shows a material beneficial ownership position of 1,506,633 shares (8.25%). The breakdown of voting and dispositive power—1,436,198 sole votes and 1,492,858 sole dispositive for Donald Smith & Co., Inc., plus 13,775 for DSCO Value Fund—provides clarity on control over trades and votes reported by the filer. The certification that holdings are passive and held in the ordinary course reduces the likelihood this filing signals an active control intent. For investors, this is a material disclosure of concentrated ownership but not an activist stake based on the filer’s statement.

Corporate Governance Expert

TL;DR: A clear passive disclosure of a significant equity position; governance risk appears limited per the filing's certification.

The filing identifies Donald Smith & Co., Inc. as investment advisor with beneficial ownership across advisory clients and confirms that ultimate rights to dividends and sale proceeds rest with those institutional clients. The Schedule 13G classification and the explicit certification that shares were not acquired to influence control indicate this is a passive disclosure rather than an attempt to form or lead a group. The provided voting and dispositive power numbers are sufficient for assessing the filer’s direct control over the reported shares.
