Context
RSU grants are common retention/compensation tools and do not involve an outlay of cash by the insider. The economic value to the insider will depend on Constellium’s stock price when the RSUs vest (March 12, 2029). Awards like this are not the same signal as an outright purchase or sale and should be interpreted as compensation rather than a direct vote of confidence or sell signal.
