## About Carus

Carus is a global manufacturer of branded specialty chemistries for environmental applications,
with a company history spanning more than a century. Founded in 1915 by Edward Hegeler Carus in
LaSalle, Illinois to address a wartime shortage of potassium permanganate, the company has grown
into a global provider of chemistries that treat water, air, and soil.

Carus remains closely tied to its origins in Illinois' Starved Rock Country and describes itself
as a mission-driven organization built on continuous research, technical excellence, and customer
collaboration. The company is now led by the third generation of the Carus family, with Inga Carus
serving as President and CEO since 2005.

**Tagline:** "Responsible Chemistry. Innovative Solutions."

**Mission:** To deliver sustainable chemistry solutions that help clean and protect water, air,
and soil, advancing innovation, ensuring safety, and enabling a healthier planet for current and
future generations.

**Manufacturing footprint:** Products are made in the USA using globally sourced components.

## Company History Highlights

- **1915:** Edward Hegeler Carus begins manufacturing potassium permanganate in a makeshift lab
  to address a wartime shortage.
- **1920s:** Carus is the only one of over 20 shuttered U.S. permanganate producers to reopen.
  Karl Kleimenhagen invents the world's first electrolytic permanganate cell.
- **1930s:** Expands into manganese sulfate (fertilizer use) and hydroquinone (photo development).
- **1940s:** WWII spikes demand for potassium permanganate (used in nylon production); Carus
  declines the Army-Navy E Award to avoid publicity and sabotage risk.
- **1950s-60s:** Becomes the world's largest producer of potassium permanganate; creates the
  CAIROX® brand.
- **1970s:** Develops air scrubbing technology; helps industries meet new EPA and Safe Drinking
  Water Act regulations.
- **1980s:** Enters wastewater treatment, air purification, and electronics chemistries; even
  supplies a product used to create the stone-washed denim look.
- **1990s:** Enters soil and groundwater remediation, treating chlorinated ethenes.
- **2000s:** Acquires the potassium permanganate business of Industrial Química del Nalón (IQN)
  in Oviedo, Spain, forming the European subsidiary. Also acquires a phosphate company in
  Belmont, NC. Inga Carus becomes President and CEO (2005), the third generation of family leadership.
- **2019:** Welcomes a strategic investment and long-term partnership with Seidler Equity Partners.
- **2023-2024:** Rebuilds and expands packaging and warehouse facilities following a January 2023
  fire, with enhanced safety and sustainability measures.
