To the Global EFI team,

I am excited to share the news that today EFI’s Board of Directors has unanimously approved an agreement under which EFI will be acquired by an affiliate of Siris Capital Group, LLC. Siris is a leading private equity firm focused on investing and driving value creation in technology companies that provide mission-critical solutions and are facing technology transitions.

After an extensive evaluation process, our Board of Directors determined that Siris’ proposal is a compelling transaction that will provide shareholders with immediate and substantial cash value while allowing us to enhance our focus on customer and partner success. Importantly, we believe private ownership by a supportive and value-adding partner will allow us to make long-term, strategic investments in our relationships with our customers, partners and employees, as well as our technology and systems.

We expect the transaction to be completed by the third quarter of 2019, subject to customary closing conditions and approvals, as described in the press release. Upon closing of the transaction, an affiliate of Siris will acquire all EFI stock for $37.00 per share in cash, for a total enterprise value of approximately $1.7 billion. At that time, EFI will no longer be a public company traded on the Nasdaq stock exchange. Instead, we will become a private company owned by an affiliate of Siris Capital.

EFI may solicit alternative acquisition proposals from third parties during a “go-shop” period over the next 45 calendar days. EFI will have the right to terminate the agreement to enter into a superior proposal subject to the terms and conditions of the agreement. There is no guarantee that this process will result in a superior proposal, and the agreement provides an affiliate of Siris with a customary right to attempt to match a superior proposal. EFI does not intend to disclose developments with respect to the solicitation process unless and until it determines such disclosure is appropriate or is otherwise required.

Although this is an exciting announcement, we recognize that it will lead to some change—notably a change in our corporate ownership, and we know that you will have questions about what this means for you. Any decisions regarding changes in personnel will be communicated as far in advance as possible. You have our commitment that we will communicate openly and treat employees fairly. Please know that we will make frequent efforts to keep you updated through a variety of methods, and the linked FAQs answer some questions that may be top of mind. If you have other questions, please submit them to Vicki Sam at vicki.sam@efi.com, and we will continue to build out the FAQs so they are a useful resource for you.

Siris’ investment in EFI is a strong endorsement of our mission to accelerate the transformation of industries where colorful images matter. With Siris’ partnership—and guidance—we believe we can further refine and accelerate our strategy and deliver significant value to our customers. Siris’ approach is one of empowering and supporting management teams, and Siris expects to operate EFI as a stand-alone entity after the closing of the transaction.

As we work to complete this transaction, I need all employees to remain laser focused on executing on our current business priorities and servicing our customers and partners better than ever.

Please stay focused, remain confident in our strategy, and refrain from speculating about what this means. Like many other public companies that have gone private and thrived, it is in our hands to capitalize on this new opportunity and make this an extremely positive phase in EFI’s journey.

Thanks,

Bill
