Ingevity Corporation (NYSE: NGVT) stock plummeted 5.04% intraday on Thursday, reacting to the company's fourth-quarter and full-year 2024 earnings results and cautious guidance for 2025.

The key negative points from the earnings call that likely impacted the stock price negatively include:

• Full-year sales of $1.4 billion were down 17% from the previous year, primarily due to a $300 million drop in Performance Chemicals sales.
• Ingevity reported a GAAP net loss of $430 million, reflecting several non-recurring charges related to repositioning actions.
• Performance Chemicals revenue declined by 33%, with a significant portion due to exiting lower margin markets and adverse weather impacting Road Technologies.
• The company faced competitive pressures and unfavorable product mix in Advanced Polymer Technologies, leading to an 8% revenue decline.

Additionally, the Q&A section highlighted some concerns regarding input costs and potential tariff impacts:

• Ingevity expects higher input costs in 2025 due to rising natural gas prices, which may impact Performance Materials margins.
• While tariffs have had minimal impact so far, potential changes could affect automotive production and consumer demand in the U.S., negatively impacting the company's performance.
