Exhibit 99.2

ANNOUNCEMENT

Date:                September 28, 2017

Subject:            Our Next Chapter

Dear Exa Team Members,

I’m writing to you today to share with you exciting news about the future of Exa. Early this morning the company issued a press release (see attachment) announcing that we have reached an agreement to be acquired by Dassault Systèmes.

Dassault has agreed to pay $24.25 per share of Exa stock – providing a significant premium to our shareholders and valuing the company at approximately $400M. This price reflects the strong value Dassault sees in Exa’s technology, products and solutions and most importantly, in the team that continues to develop and deliver our solutions to our customers.

Over the years, we built a strong partnership with Dassault to serve our customers. I have come to see a very strong alignment of go-to-market visions between our two companies. As a result, I am excited about the potential that Dassault’s resources and reach can provide to help scale our business faster and accelerate our entry in to new vertical markets.

I fully recognize that this change presents challenges and concerns in addition to opportunities. While we understand the potential, we do not yet know many of the details as to how we will work collectively to take this important next step. This is the task that now lays ahead of us and I ask each of you for your full engagement and support in the process. As has always been the case, we need your help to find the right path forward so that the next exciting chapters of Exa can be written.

Please join our company meeting Thursday at 8:30 am Boston time to hear more about this exciting news.

Sincerely,

Steve Remondi

President & CEO

Exa Corporation
