Exhibit 99.4

Email Notice to CompoSecure Employees

We are pleased to share some exciting news with you about an important milestone for CompoSecure.

What’s new?

Today, we announced plans to become a publicly traded company through a proposed merger with Roman DBDR Tech Acquisition Corp., with the support of major institutional investors including BlackRock and Highbridge. Roman DBDR is what’s known as a SPAC (Special Purpose Acquisition Company). It went public in November 2020 with the intent to identify and merge with a company in the technology, media and telecom (“TMT”) industries. While today’s announcement is an important step, it does not yet make CompoSecure a public company, nor does it guarantee that the proposed transaction will close – though we expect to begin trading on the NASDAQ in Q3 2021. The full press release announcing the transaction can be seen here [link to press release].

What does ‘going public’ mean for CompoSecure?

Going public is the next major step in the evolution of CompoSecure. As a public company, we will continue our tradition of helping our clients offer their customers highly differentiated payment products and solutions, while accelerating our growth by investing in opportunities to scale the business and to capture more of our addressable market.

I want to take this opportunity to thank the entire CompoSecure team for your contributions. Without your hard work, dedication, focus on quality, safety and on-time delivery, our success would not be possible.

What does ‘going public’ mean for you?

First and foremost, it means business as usual. While our company’s capital structure is changing, most employees will see no change in how they do their jobs and serve our customers. Being a public company will enable greater opportunities for all employees, fuel product innovation, and help accelerate our growth. While this is an exciting time, it is important that we all remain focused on what has made CompoSecure stand out and what will continue to fuel our success: delivering extraordinary results for our clients, driving innovation in payments and security, and continuing to focus on quality, safety, and on-time delivery.

What’s next?

Now that this news has been announced, we anticipate a heightened level of interest from people seeking information that could be used to form an opinion about our current or future performance. Today's announcement will likely also lead to increased media and investor interest in our company. It is important that we speak in one voice, so please refrain from commenting to the media and refer all media and investor inquiries to me, Tim Fitzsimmons or Lewis Rubovitz. I would like to remind all employees, it is against company policy for employees to speak to the media on behalf of the company, unless specifically authorized, in addition to not share or post on social media any confidential information about CompoSecure or our customers, including production data, card programs in our facilities or similar information.

In closing, I want to express my gratitude to each of you. This extraordinary milestone is the result of a team effort and would not have been possible without your hard work and dedication.

Thank you,

Jon Wilk

Email Notice to Existing CompoSecure Members

Dear CompoSecure Members,

As you may have seen, I’m excited to share that CompoSecure today announced plans to become a publicly traded company through a proposed merger with Roman DBDR Tech Acquisition Corp., with the support of major institutional investors including BlackRock and Highbridge.

Roman DBDR is what’s known as a SPAC (Special Purpose Acquisition Company). It went public in November 2020 under the ticker DBDR with the intent to identify and merge with a company in the technology, media and telecom (“TMT”) industries.

While today’s announcement is an important step, it does not yet make CompoSecure a public company, nor does it guarantee that the proposed transaction will close. Assuming the transaction closes, we expect to begin trading on the NASDAQ in Q3 2021. The full press release announcing the transaction can be seen here [link to press release].

This is a very exciting time in CompoSecure’s history, and I would like to thank each of you for your commitment and support over the years to help us get to this pivotal moment.

This transaction not only gives the Company access to capital to execute its growth plan but also provides liquidity to our existing equity owners and a path to future liquidity, though we hope that you will continue to remain an investor in the company long after we go public.

Thank you for your continued support!

If you have any questions, please don’t hesitate to reach out.

Sincerely,

Jon Wilk
