DYNAMIC MATERIALS REPORTS FOURTH QUARTER

AND FULL-YEAR FINANCIAL RESULTS

BOULDER, Colo. — February 27, 2013 — Dynamic Materials Corporation (DMC) (Nasdaq: BOOM), today reported financial results for its fourth quarter and fiscal year ended December 31, 2012.

Fourth quarter sales were $52.5 million, down 3% from $54.3 million reported in last year’s fourth quarter, but a 5% sequential improvement from third quarter sales of $50.1 million.  Fourth quarter gross margin improved to 31% from 27% in the year-ago fourth quarter and was unchanged compared with the third quarter.

Operating income was $4.5 million, down 13% from $5.2 million reported in both last year’s fourth quarter and the 2012 third quarter.  Net income was $2.9 million, or $0.21 per diluted share, down 21% from $3.6 million, or $0.27 per diluted share, in the year-ago fourth quarter, and a decline of 24% from net income of $3.8 million, or $0.28 per diluted share, in the third quarter. The decline in operating income reflects $672,000 in stock-based compensation expense related to the accelerated vesting of restricted stock awards associated with management retirements.

Adjusted EBITDA was $9.1 million, up 5% from $8.7 million in last year’s fourth quarter, and a 2% increase from the $9.0 million reported in the third quarter.  Adjusted EBITDA is a non-GAAP (generally accepted accounting principles) financial measure used by management to measure operating performance.  See additional information about adjusted EBITDA at the end of this news release, as well as a reconciliation of adjusted EBITDA to GAAP measures.

Adjusted EBITDA increased 2% to $33.6 million from $32.9 million in 2011.  Cash flow from operating activities more than doubled to $20.0 million versus $9.7 million during the prior year.

Management Commentary

Yvon Cariou, president and CEO, said, “Although global economic conditions during 2012 slowed capital investment activity in our end markets, the year was marked by several strategic achievements that have further strengthened DMC’s structural foundation, as well as its prospects for long-range growth.  We enhanced the management teams of all three business segments, established a much stronger foothold in Asia, initiated the construction of major oilfield-product production facilities in Russia and North America, and expanded our customer base and end markets at AMK Welding.  Most importantly, the recent selection of Kevin Longe as my successor has ensured that DMC is supported by very strong leadership.  I am proud of the selection and transition process we executed during the past year, and could not be more confident in Kevin’s vision for the Company and his skill as a leader.  As I’ve said previously, I look forward to working closely with him from my position on the board of directors.”

Longe, who assumes the role of president and CEO on March 1, said, “We have worked hard in recent months to solidify the roadmap for DMC’s future, and I am very encouraged about the opportunities we have identified for each of our business segments and the Company as a whole.

“Our near-term focus will be both on the execution of several strategic and operational initiatives currently underway, and on achieving our sales and profit objectives in the face of continued challenging economic conditions.  Our Nobelclad team is working hard to capture some large order opportunities in the upstream energy and petrochemical sectors; our DYNAenergetics team is focused on the build-out of our shaped charge plants in Texas and Siberia, and enhanced product and inventory management programs; and we are expanding our overall sales and marketing presence in China, to name just a few.

“Our longer range objective is to accelerate the growth and cash flow generation of our existing segments.  We also intend to expand our family of technical niche businesses serving the global energy, infrastructure and industrial markets.  I believe we have established a very compelling strategy for enhancing our growth and bolstering shareholder value, and I look forward to leading DMC in the pursuit of our growth objectives.”

Guidance

Rick Santa, senior vice president and chief financial officer, said, “Based on the project opportunities we see at Nobelclad and the full-year sales forecasts at DYNAenergetics and AMK Welding, we currently anticipate our consolidated sales for 2013 will increase by 8% to 10% from the $201.6 million reported in 2012.  We also expect our gross margin will be in a range of 27% to 29% versus the 30% we reported in 2012.”

Santa said DMC’s blended effective tax rate for the full-year of 2013 is projected to be in a range of 20% to 22%.  The anticipated reduction versus the 2012 tax rate of 29.3% reflects the impact of certain recently enacted federal tax legislation that is applicable to 2012, but must be recognized in 2013 according to GAAP.  To reflect the effect of the legislation, the Company will recognize a tax benefit of approximately $900,000 in the 2013 first quarter.  Excluding the impact of the first quarter tax benefit, the blended effective tax rate for fiscal 2013 is projected to be in a range of 25% to 27%.

Given the recent dip in backlog at Nobelclad, management anticipates sales in the first fiscal quarter will decline between 7% and 10% versus the $50.2 million reported in the first quarter of 2012.  Gross margin is expected in a range of 27% and 28%.  During the quarter, the Company also expects to record a one-time expense of approximately $3.0 million associated with management retirements.

Use of Non-GAAP Financial Measures

Non-GAAP results are presented only as a supplement to the financial statements based on U.S. generally accepted accounting principles (GAAP). The non-GAAP financial information is provided to enhance the reader’s understanding of DMC’s financial performance, but no non-GAAP measure should be considered in isolation or as a substitute for financial measures calculated in accordance with GAAP. Reconciliations of the most directly comparable GAAP measures to non-GAAP measures are provided within the schedules attached to this release.

EBITDA is defined as net income plus or minus net interest plus taxes, depreciation and amortization. Adjusted EBITDA excludes from EBITDA stock-based compensation and, when appropriate, other items that management does not utilize in assessing DMC’s operating performance (as further described in the attached financial schedules). None of these non-GAAP financial measures are recognized terms under GAAP and do not purport to be an alternative to net income as an indicator of operating performance or any other GAAP measure.

Management uses these non-GAAP measures in its operational and financial decision-making, believing that it is useful to eliminate certain items in order to focus on what it deems to be a more reliable indicator of ongoing operating performance and the company’s ability to generate cash

flow from operations. As a result, internal management reports used during monthly operating reviews feature the adjusted EBITDA. Management also believes that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. EBITDA and adjusted EBITDA are also used by research analysts, investment bankers and lenders to assess operating performance. For example, a measure similar to EBITDA is required by the lenders under DMC’s credit facility.

Because not all companies use identical calculations, DMC’s presentation of non-GAAP financial measures may not be comparable to other similarly titled measures of other companies. However, these measures can still be useful in evaluating the company’s performance against its peer companies because management believes the measures provide users with valuable insight into key components of GAAP financial disclosures. For example, a company with greater GAAP net income may not be as appealing to investors if its net income is more heavily comprised of gains on asset sales. Likewise, eliminating the effects of interest income and expense moderates the impact of a company’s capital structure on its performance.

All of the items included in the reconciliation from net income to EBITDA and adjusted EBITDA are either (i) non-cash items (e.g., depreciation, amortization of purchased intangibles and stock-based compensation) or (ii) items that management does not consider to be useful in assessing DMC’s operating performance (e.g., income taxes and gain on sale of assets). In the case of the non-cash items, management believes that investors can better assess the company’s operating performance if the measures are presented without such items because, unlike cash expenses, these adjustments do not affect DMC’s ability to generate free cash flow or invest in its business. For example, by adjusting for depreciation and amortization in computing EBITDA, users can compare operating performance without regard to different accounting determinations such as useful life. In the case of the other items, management believes that investors can better assess operating performance if the measures are presented without these items because their financial impact does not reflect ongoing operating performance.
