On September 25, 2024, the following email was sent to Markforged Holding Corporation employees:

Team,

For more than a decade, Markforged has been on a journey to introduce the world to the leading industrial-grade 3D printing and to revolutionize manufacturing along the way. I’m excited to announce that today we are embarking on the next phase of our journey through a merger with Nano Dimension (who is also in the process of acquiring Desktop Metal) to build a world-leading innovative additive company! You can read the joint press release we issued here.

By combining our businesses, we believe we will be best positioned to drive growth and serve our customers with the most impressive portfolio of innovative additive manufacturing technologies for true production applications. Together, Markforged and Nano Dimension will have the scale and financial resources that we believe will enable us to execute our long term strategic objectives and become the solution of choice for every manufacturing floor for many years to come!

We also believe this merger will create career development opportunities for many of you as we combine our businesses and will ensure our long term path to sustainability.

The transaction is currently expected to be completed by the first quarter of 2025, pending regulatory approvals and other customary closing conditions, including Markforged shareholder approval.

No doubt you will have a lot of questions. As with any transaction, we will be able to answer some of those questions now, and a lot more later as things progress and we get more clarity. We will make sure to keep you all informed and up-to-date as transparently as possible. Thank you for your patience and your continued focus and efforts as we work through those details.

Until the transaction closes, we will continue to operate as independent companies, so it remains business as usual. During this crucial time, we need to keep laser focused on delivering value to our customers and continue growing our business and hitting our targets!

We expect that today’s announcement will lead to increased inquiries from the media and our investors. If you receive questions from the media, please forward them to Sam Manning at sam.manning@markforged.com. Inquiries from analysts or investors should be sent to Austin Bohlig at investors@markforged.com.

I’m excited for the future ahead for Markforged and our amazing #oneteam — thank YOU once again all for all the hard work towards this amazing milestone!
