# Olin cuts Q4 2025 adjusted EBITDA outlook to ~$67M from prior $110-130M

## Summary
- Adjusted EBITDA now ~$67M, down from prior guidance of $110M-$130M.
- Shortfall primarily in Chlor Alkali Products & Vinyls due to extended planned turnaround and unplanned downtime at Freeport, TX.
- Lower-than-expected pipeline chlorine demand also weighed on results.
- Freeport operations have returned to normal; company reaffirms disciplined value-first commercial approach.
- CEO notes interruption of third-party raw material supply as an additional factor.
