Neogen Corp (NEOG) shares plummeted 7.56% in pre-market trading on Tuesday following the release of its fourth-quarter 2025 financial results, which fell short of analyst expectations and revealed a substantial net loss.

The company reported adjusted earnings per share of $0.05 for the quarter, significantly missing the analyst consensus estimate of $0.09 and marking a 50% decrease from $0.10 per share in the same period last year. More alarmingly, Neogen posted a staggering net loss of $612.196 million for the quarter, contributing to the negative market reaction.

Despite the earnings disappointment, Neogen's quarterly revenue of $225.459 million slightly exceeded analyst estimates of $221.923 million. However, this still represented a 4.79% decrease compared to the previous year's $236.794 million. Looking ahead, the company provided guidance for fiscal year 2026, projecting revenue in the range of $820 million to $840 million, which aligns with current market expectations. The mixed results and significant net loss appear to have overshadowed the modest revenue beat, leading to the sharp pre-market decline in Neogen's stock price.
