We present Specialty Platform sales, gross margin, selling and administration, and operating income because management believes that this is useful information to investors by highlighting our collective progress in advancing our specialization strategy.

Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy

This has been a multi-year journey for us that reflects the investments we have made in sustainability, advancing diversity and inclusion, and workplace flexibility."

Our offerings include specialty engineered materials, advanced composites, color and additive systems and polymer distribution. Global technology enables the management approach, and it is critical to our strategy for career advancement. The most advanced LSS training is for Black Belt level project leaders.

Our focus on people is advancing our Diversity & Inclusion commitment as well. Combined with the rooftop panels we installed in prior years, our Assesse facility now draws 80% of its required production energy from solar and wind sources. Our systems, networks and products may be vulnerable to advanced persistent threats or other types of system failures.
