Olin Corporation (NYSE: OLN) saw its stock surge 5.77% in after-hours trading on Thursday, following the release of its first-quarter 2025 financial results that significantly exceeded analyst expectations. The chemical manufacturer demonstrated resilience in a challenging market environment, posting strong revenue growth and a surprise profit.

Olin reported Q1 revenue of $1,644.2 million, surpassing the analyst consensus estimate of $1,578 million by 4.20%. This represents a slight increase of 0.55% compared to the same period last year.

Although this marks a 97.5% decrease from the $0.40 per share earned in the same quarter last year, the ability to remain profitable in a tough economic climate is noteworthy.

Further bolstering investor confidence, Olin's Q1 adjusted EBITDA reached $185.6 million, significantly outperforming the IBES estimate of $160.1 million. Looking ahead, the company provided guidance for Q2 2025, projecting adjusted EBITDA in the range of $170 million to $210 million. This positive outlook, combined with the strong Q1 performance, likely contributed to the stock's after-hours rally. Investors appear optimistic about Olin's ability to navigate current market challenges and maintain profitability in the coming quarters.
