DYNAMIC MATERIALS REPORTS FIRST QUARTER FINANCIAL RESULTS

BOULDER, Colo. — April 28, 2011 — Dynamic Materials Corporation (DMC) (Nasdaq: BOOM), a diversified provider of industrial products and services, and the world’s leading manufacturer of explosion-welded clad metal plates, today reported financial results for its first quarter ended March 31, 2011.

First quarter sales were $45.6 million, up 50% from sales of $30.4 million in last year’s first quarter and a 2% sequential improvement from sales of $44.8 million in last year’s fourth quarter. Gross margin was 23%, flat versus the first quarter last year and up from 22% in the fourth quarter.

First quarter operating income was $1.5 million versus $245,000 in the prior year’s first quarter and $1.5 million in the 2010 fourth quarter. Net income was $750,000, or $0.06 per diluted share, versus a net loss of $412,000, or $0.03 per diluted share, in last year’s first quarter, and net income of $1.3 million, or $0.10 per diluted share, in the fourth quarter.

First quarter adjusted EBITDA was $5.1 million versus $3.5 million in last year’s first quarter and $5.4 million in the fourth quarter.  Adjusted EBITDA is a non-GAAP (generally accepted accounting principle) 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.

Explosive Metalworking

DMC’s Explosive Metalworking segment recorded first quarter sales of $26.1 million, up 22% from sales of $21.3 million in the same quarter of 2010.  Operating income was $1.6 million compared with $1.8 million in the 2010 first quarter, while adjusted EBITDA was $3.0 million versus $3.2 million.  Order backlog increased to $58.5 million compared with $56.5 million at the end of the 2010 fourth quarter.

Oilfield Products

Sales at DMC’s Oilfield Products segment increased 143% to $17.1 million from $7.0 million in the 2010 first quarter. Excluding sales contributions of $3.5 million from operations acquired since last year’s first quarter, Oilfield Product sales increased $6.5 million, or 93%, versus the comparable year-ago quarter. Operating income was $924,000 versus a loss from operations of  $460,000 in the prior year’s first quarter, while adjusted EBITDA was $2.1 million compared with $473,000 in the 2010 first quarter.

AMK Welding

DMC’s AMK Welding segment reported first quarter sales of $2.4 million, up 20% from $2.0 million in the same quarter of 2010.  Operating income increased to $468,000 from $260,000 in the comparable prior year quarter.  The segment recorded adjusted EBITDA of $590,000 versus $375,000 in the comparable quarter last year.

Management Commentary

“With global economic conditions slowly gaining strength, each of our business segments delivered much improved financial results versus last year’s first quarter,” said Yvon Cariou, president and CEO.  “We continue to see signs that industrial capital spending activity within many of our Explosive Metalworking markets is gradually gaining momentum, particularly in the energy sector.  Moreover, quoting activity remains very healthy.  While the timing of contract awards remains difficult to predict, we are encouraged by the improving business conditions for our core operating segment.”

Cariou said DMC’s Oilfield Products business continues to benefit from a very active exploration and production environment, as well as expanding use of directional drilling technologies.  “Setting aside acquired operations, this segment nearly doubled its top-line results versus the first quarter last year.  We are very pleased with the progress we have made at assimilating our recently acquired Oilfield Product businesses, and continue to evaluate a range of opportunities that could further accelerate the growth of this business segment.”

Guidance

Rick Santa, senior vice president and chief financial officer, said, “Given the continued backlog growth at our Explosive Metalworking segment and the expected full-year sales growth of our Oilfield Products and AMK Welding segments, we are elevating our 2011 sales-growth forecast to a range of 24% to 28% versus 2010.  We had previously forecast year-over-year sales growth in a range of 20% to 25%.  We have maintained our full-year gross margin forecast of between 24% and 26%.”

Santa said second quarter sales are expected to increase 10% to 15% from that reported in the first quarter, while gross margin is expected to improve to a range of 24% to 25%.

DMC’s blended effective tax rate for fiscal 2011 is now projected in a range of between 25% and 28% versus the previously forecasted range of 27% to 29%.  That rate is expected to rise to a normalized level of between 28% and 30% in years thereafter.

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.
