“Conflict Metals” Commitment
W e at Stack pole Electronics, Inc . are j oined with our i n dus try in opposing t he us e of m etals mined in the “conflict region”
of the eastern D emocratic Republic of t he Congo (D RC) in our products. Recognizin g that the su pply chain for m etals
used in th e electronics industr y is very com plex, we work closely with our ow n suppliers to verify to the ex tent possible
that the materials and products we supply do not contain metals sourced from this conflict region. As such, we are in
compliance with the requirements of Dodd-Frank Act regarding Conflict Minerals.
