Hi Magali,

I hope all is well. | wanted to thank you for your talk and coming to MIT several weeks ago. | took
sometime to reflect on your talk and | wanted to say | really appreciated it. It left me inspired about what Holcim’s future will be and your values. | believe if was an undergrad I’d have been drawn to your
company with the vision you’re sharing. Hopefully you can present to the undergrad population at some
point. You could really shape some career paths and view of established companies. Thanks.

Best,

Augustine.
