QuidelOrtho stock (ISIN US7476011036) last closed at USD 11.12 on Nasdaq on September 14, 2026, representing a daily decline of 5.6 percent and leaving the shares near their recent lows as of mid-September 2026.

Insider RSU vesting draws attention

According to StockTitan, a Form 4 filing shows that 2,566 restricted stock units for Chief Human Resources Officer Ronald Lee Bowman converted into 2,566 common shares of QuidelOrtho on September 15, 2026.

The same filing reports that 921 of these common shares were withheld and delivered back to the company at a price of USD 10.63 per share to cover tax withholding obligations on September 15, 2026, implying a tax-related transaction value of about USD 9,790 at that price level.

Price level and recent trading context

Per Nasdaq data reflected on a major financial portal, QuidelOrtho stock closed at USD 11.12 on Nasdaq on September 14, 2026, down USD 0.66 or 5.6 percent from the previous close, with a modest after-hours rebound to USD 11.17 on the same date.

At that closing level of USD 11.12 on September 14, 2026, QuidelOrtho shares were trading close to the price of USD 10.63 observed in the insider tax-withholding transaction on September 15, 2026, underscoring that the stock has been hovering near the lower end of its trading band in recent days.

Stock performance remains under pressure

For investors, the combination of a 5.6 percent drop to USD 11.12 on September 14, 2026 and an insider withholding price of USD 10.63 on September 15, 2026 illustrates how QuidelOrtho stock has recently been priced only about 4.4 percent above the level at which shares were surrendered to cover taxes.

While the Form 4 event on September 15, 2026 is primarily administrative in nature, it comes against the backdrop of a depressed share price that leaves QuidelOrtho stock trading far below historical peaks, making valuation and execution on the company’s diagnostics strategy key points of attention for market participants.

As of the most recent completed session on September 14, 2026, QuidelOrtho stock closed at USD 11.12 on Nasdaq, with an after-hours indication of USD 11.17, highlighting a weak near-term performance despite the routine insider RSU vesting reported one day later.
