Olin (OLN) Valuation Check After Disappointing Preliminary Q4 2025 Guidance And Earnings Reset

Despite the softer preliminary Q4 2025 guidance, Olin’s recent share price momentum has been strong, with a 30 day share price return of 22.10% and a 90 day share price return of 19.63%, while the 3 year total shareholder return of 52.75% decline shows that longer term holders have had a tougher experience.

Curious which moving parts matter most in that fair value cut and what would need to change for the gap to close?

Result: Fair Value of $22.07 (OVERVALUED)

Another View: Sales Multiple Points to a Different Story

While the narrative fair value of $22.07 suggests Olin is 15.2% overvalued at $25.41, the current P/S ratio of 0.4x tells a different story. That is well below peers at 1.3x, the US Chemicals industry at 1.2x, and even the 0.8x fair ratio the market could move toward. For you, that gap raises a simple question: is the price reflecting too much caution, or is it just catching up with the risks already on the table?
