Letter from the Chairman

Concurrent with the strategic and operational initiatives being directed by DMC’s management, the Board of Directors has been active monitoring the Company’s progress, mentoring the executive team and providing strategic guidance and feedback where appropriate.

Broadly speaking, the Board’s focus is divided among five areas: 1) Governance best practices, with appropriate attention to the Foreign Corrupt Practices Act (FCPA) and comparable anti-corruption laws in other countries given DMC’s global operations; 2) Safety and security, which is particularly relevant at DMC given the extensive use of explosives by both of its businesses 3) Risk assessment and mitigation, 4) Ensuring the integrity of our financial reports, and 5) Feedback and guidance on the strategic initiatives established by management.

During 2015 the executive team is implementing a series of these initiatives in its effort to improve operational efficiencies, reduce costs, expand geographic reach and strengthen the Company’s financial performance. At the Board level, the initiatives we are most closely monitoring are:

The opening of NobelClad’s new production facility in Liebenscheid, Germany and the consolidation of the business’ European cladding operations

The consolidation of DynaEnergetics’ North American manufacturing and distribution operations

The commercial start-up of DynaEnergetics’ shaped charge facility in Tyumen, Siberia

Ensuring that issues related to DMC’s tax structure, which led to a year-end restatement of past financial results, are fully corrected, and enhanced controls are in place to prevent a recurrence of any similar incidents

An important component of DMC’s growth strategy is the pursuit of attractive acquisition opportunities in the energy and industrial infrastructure sectors that could accelerate growth, diversify the Company’s revenue streams and leverage its global infrastructure. The Board is fully supportive of this strategy, and will closely examine any and all potential transactions for proper strategic fit, adequate value creation, and positive impact on DMC’s balance sheet and cash flow.

At this year’s Annual Meeting of Stockholders, two of our nine Directors will not stand for re-election: Bernard Hueber who served as a DMC director from 2000 to 2005 and again from 2006 until 2015; and Rolf Rospek, who has been a Director since 2007. Both men provided the Board and the Company with invaluable expertise and guidance. We thank them for their distinguished service and wish them well in the future.

The enthusiasm conveyed about DMC’s future in Kevin’s Longe’s accompanying letter is shared by your Board of Directors. You can rest assured that both your Board and management team will continue to place their highest priority on one key objective: the enhancement of stockholder value.

Very faithfully yours,
