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.

Lantheus Holdings Inc (LNTH)

Q3 202626 Jun – 14 Aug 2026

Curium's $8B buyout and new FDA approval reshape Lantheus

Curium agrees to acquire Lantheus for up to $8 billion Curium will pay $102.50 per share in cash plus up to $12 more if sales targets are met, a 14.9% premium. This puts a firm floor under the stock and is the main reason it trades near the offer price.
The buyout is the single biggest force driving LNTH's price and future value.
FDA approves Tauklarify for tau PET imaging The FDA approved Tauklarify, a new imaging agent for Alzheimer's tau pathology. This adds a new product to Lantheus's portfolio and could support the contingent value rights tied to future sales.
A new FDA approval is a fresh positive catalyst that can affect the buyout's contingent payments.
FDA rejects LNTH-2501 due to third-party facility issues The FDA issued a Complete Response Letter for LNTH-2501, a PET diagnostic for neuroendocrine tumors, because of unresolved manufacturing issues at a partner's facility. This delays a potential product but does not question the drug's data.
This is a fresh regulatory setback that could weigh on sentiment and future growth prospects.
