This substantial investment, now representing 3.94% ownership with a market value of approximately $90.13 million, demonstrates strong confidence from a major institutional investor.

The Investment Story: September was a month of conflicting signals for QuidelOrtho, marked by a large institutional sell-off alongside a substantial investment from AQR Capital Management and ongoing legal scrutiny. The mixed analyst sentiment and fluctuating stock price reflect this uncertainty.

What It Means for Investors: The contrasting moves by Magnetar and AQR create a complex picture. While the legal investigation adds risk, the significant investment from AQR suggests some investors see long-term potential. Investors should carefully weigh these factors and monitor the upcoming Baird conference for further clarity.

Looking Ahead: Investors should closely monitor the outcome of the shareholder claims investigation and any further developments regarding the Savanna RVP4 Test launch. Analyst reactions following the September 10, 2025, Baird conference will also be crucial.

The Bottom Line: QuidelOrtho remains a cautiously neutral investment. The mixed signals this month highlight the need for investors to carefully evaluate the company’s strategy and address the legal concerns before making any decisions.
