Insights
Wellington reports a passive 6.48% CRL stake.
Wellington and affiliates disclosed beneficial ownership of 3,190,467 CRL shares on a Schedule 13G/A, signaling a passive filing status. The group reports shared voting and dispositive power and no sole authority, consistent with institutional asset management on behalf of clients.
The certification confirms ordinary-course investing and no intent to influence control, aligning with a 13G profile. Because holdings are spread across advisory clients and no single client exceeds five percent, concentration risk appears limited in this excerpt.
Actual market impact depends on holder decisions and future ownership changes; subsequent filings may provide updated percentages or share counts.
