Insights

Securities Analyst

TL;DR: Wasatch holds a material 8.3% passive stake with sole dispositive control of 13.53M shares; impact is notable but appears non-control.

Wasatch Advisors reports beneficial ownership of 13,532,882 shares, equal to 8.3% of Certara's common stock, exceeding the 5% reporting threshold that triggers public disclosure requirements. The filing specifies sole dispositive power over all reported shares and sole voting power over 9,969,332 shares, which confirms Wasatch's ability to sell or direct disposition unilaterally while voting a somewhat smaller subset of that position. The certification that holdings are in the ordinary course of business and not intended to influence control frames this as a passive institutional stake rather than an activist move.

Corporate Governance Expert

TL;DR: The filing documents meaningful influence through dispositive authority but includes an explicit certification of non-control intent.

The report documents that Wasatch has sole dispositive authority for the full reported position, which is material from a governance perspective because such authority enables unilateral disposition of shares. However, the filer attests the position was not acquired to change or influence issuer control and was held in the ordinary course of business, indicating no expressed intent to seek board changes or control actions. For directors and investors, the combination of sizeable ownership and a non-control certification should be monitored for any future changes in voting or disposition statements.
