Dear Valued Customer,

Woefully, the current events in Ukraine continues to intensify. Our thoughts and prayers are with those that are being impacted by these violent and hostile
actions. How this will conclude, Concorde can only speculate since these egregious and aggressive actions are unprecedented in this modern world. Concorde wants our customers to know that we are monitoring the situations, both in the U.S. and abroad, to ensure our ability to meet our customers’ requirements.
Our ongoing success during times of this nature are supported by:

o Contingency plans with secondary and tertiary suppliers of our raw materials
o Our logistics teams have the knowledge and ability to redirect our container fleet if required
o Concorde is currently using our global network to ensure we explore every advantage of our 2022 requirements
o Our quick response team has been tasked with the goal of identifying potential risk exposures and developing mitigation strategies

Concorde does not see any significant impacts in the near future, but to be fully transparent, this aggressive behavior seriously concerns us, and we are doing everything
possible to satisfy your needs and continue in being your premier global supplier of Sulfur Hexafluoride Gas.

Sincerely,

Robert Laverne
Director
