Allied Mineral Products was established 60 years ago today. From an investment of a few thousand dollars by
our founders Bob Scott and Bill Winemiller, Allied has become a multi-hundred-million-dollar, global
corporation. We have operations at 12 manufacturing facilities in 8 countries. We have customers in more
than 125 countries. We have over 1,000 employees located in more than 25 countries. Every day we keep our
promise of “Being There Worldwide.”

With Mr. Winemiller’s retirement in 1976, we started our ESOP to empower employees to take more
responsibility through company ownership. The ESOP was expanded in 1986 when Mr. Scott retired. The
ESOP remains at the core of our culture today. More than 112 people have retired from Allied with their ESOP
helping guarantee their financial security. And in countries where we cannot operate as an ESOP, our culture
stands just as strong with employees at the center and success the common focus.

So much has happened in 60 years. We were first to go to South Africa in 1998 after apartheid ended. We
were first into China in 1999 when most others stayed away. With NAFTA we saw opportunity and opened a
plant in Brownsville, Texas in 2002. We built the first new refractory plant in Western Europe (The
Netherlands) in many years in 2005. We boldly started in India (2011) and Russia (2017). We proved that
Allied’s culture works regardless of location or nationality.

We have expanded our production, administrative, and research facilities in Columbus, Ohio and Tianjin,
China. We acquired four refractory companies in 1991/97 (Matrix), 2002 (Chicago Fire Brick), and 2017 (Pryor
Giggey and Riverside). We expanded into new markets and new applications globally. We remain
opportunistic and focused on success.

Thank you to our employees, our customers, our suppliers, and our service providers. So many have had a
hand in our success. And so many more will help us continue to succeed.
I am proud and fortunate to lead and work with the incredible people at Allied. We have been and will
continue to be successful together.
