Quidel Corporation (QDEL)

Q3 2026
▼3▲1

QuidelOrtho slashes 2026 outlook on China and respiratory weakness

  • 2026 guidance slashed, shares plunge QuidelOrtho beat second-quarter estimates but cut full-year 2026 revenue guidance to $2.52-$2.60 billion from $2.70-$2.75 billion, and earnings guidance to 65-90 cents from $1.80-$2.00. Shares fell about 25% as investors absorbed the much weaker outlook.

    The guidance cut is the single biggest new force pushing QDEL down this period.

  • China pricing rules and weak respiratory season China's draft in-vitro diagnostics pricing guidelines expanded to six provinces, causing distributors to cut inventories faster than expected; China revenue fell 18.7%. Management also now assumes a weaker-than-average respiratory season, removing a hoped-for rebound.

    These are the specific demand problems management blamed for the guidance cut.

  • Analyst fair value and targets cut Simply Wall St cut its fair value estimate to $12 from $20.50, citing much lower growth assumptions. Analyst targets now cluster between $12 and $18, with JPMorgan at $12 (Underweight) and Citi at $18 (Neutral), showing deep disagreement on the stock's path.

    It shows how professional valuations were reset lower after the guidance cut.

  • Possible point-of-care sale could cut debt QuidelOrtho is reportedly looking to sell its point-of-care division for about $1.5 billion, which would undo the 2022 merger and leave a steadier diagnostics business. One large holder sees the stock worth roughly $100 per share if the sale happens and debt falls.

    It is the main potential upside counterweight to the weak guidance.

Neogen Corporation (NEOG)

Q3 2026

Neogen's growth bets meet an FDA safety blow

  • Q4 beat and strong FY27 guidance Neogen's fiscal fourth-quarter revenue of $225.3 million beat expectations, with core growth accelerating to 4.3% and adjusted EBITDA up 12%. It guided fiscal 2027 revenue to $880–885 million and EBITDA to $180–182 million, and repaid $20 million of debt. A stronger profit outlook lifts the stock.

    The earnings beat and guidance are the core reason the stock jumped and set the period's direction.

  • R&D boost and Petrifilm brought in-house Neogen plans to raise fiscal 2027 R&D spending about 50% and move Petrifilm manufacturing in-house, with the first sellable output starting November 2026 and at least two new product launches a year. Doing its own manufacturing can cut costs and speed new products, supporting future profit.

    This is a concrete new investment plan that shapes Neogen's growth and margins beyond the quarter.

  • FDA warning letters over contaminated horse product The FDA issued warning letters after fungal contamination was found in Neogen's veterinary product HYCOAT, linked to severe joint infections in nearly 100 horses and at least 20 deaths. Shares fell 5.4%. This raises regulatory, legal and reputational risk that can weigh on the stock.

    It is the main negative force this period and a real counterweight to the upbeat earnings news.

  • Guidance raised again above consensus Neogen lifted fiscal year revenue guidance to $885–890 million, above its earlier range and the $883.2 million consensus, sending shares up 11% before the market opened. The raise signals management sees demand holding up, which supports the stock.

    The fresh guidance increase is the newest positive catalyst and confirms the growth trend.
