DYNAMIC MATERIALS REPORTS FIRST QUARTER FINANCIAL RESULTS

BOULDER, Colo. — April 29, 2014 — Dynamic Materials Corporation (DMC) (Nasdaq: BOOM), today reported financial results for its first quarter ended March 31, 2014.

Sales increased 4% to $48.0 million versus $46.3 million in the first quarter last year, while gross margin improved to 30% from 28% in the same period a year ago.  The increase in gross margin resulted from favorable changes in product and customer mix at the Company’s Oilfield Products business, which reported gross margin of 41%, up from 34% in the first quarter last year.

Operating income was $2.8 million versus an operating loss of $1.1 million in the first quarter of 2013.  Operating results in last year’s first quarter included $3.0 million of non-recurring expenses associated with management retirements.  Net income improved to $1.6 million, or $0.12 per diluted share, versus net income of $215,000, or $0.02 per diluted share, in the year-ago first quarter.  Net income in the 2013 first quarter reflected a tax benefit of $1.2 million.

First quarter adjusted EBITDA increased 107% to $6.9 million from $3.3 million in the first quarter last year.  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.

NobelClad

NobelClad reported sales of $24.6 million, a decline of 6% from $26.2 million in the first quarter last year.  Operating income was $1.4 million versus $2.4 million in the comparable year-ago quarter.  Adjusted EBITDA was $3.1 million versus $3.9 million in the same quarter a year ago.  NobelClad ended the quarter with an order backlog of $35.9 million versus $36.9 million at the end of the fourth quarter.

Oilfield Products

First quarter sales at the Company’s Oilfield Products segment, which now includes DynaEnergetics and AMK Technical Services, increased 17% to $23.5 million from $20.1 million in the same quarter a year ago.  Operating income increased 150% to $3.6 million from $1.4 million in last year’s first quarter.  Adjusted EBITDA advanced 85% to $5.4 million from $2.9 million in the comparable prior-year quarter.

Management Commentary

Kevin Longe, president and CEO, said the first quarter reflected positive market conditions for DMC’s Oilfield Products business.  “Demand for DynaEnergetics’ DynaSelect detonator system drove improved first quarter sales and gross margin performance for DMC.  The oil and gas industry places great emphasis on reliability, safety and efficiency in its well completion technologies, and the demand for our new DynaSelect system illustrates we are facilitating more effective well completions.”

“We continue to strengthen the DynaEnergetics organization to better serve customers and support demand for our growing product offering.  Our research and development team remains very active, and we expect to introduce multiple new perforating-related products in the coming quarters.”

Longe added, “NobelClad continues to report strong quoting activity, particularly from the oil and gas and chemical sectors.  However, bookings activity remains relatively modest.  Sluggish demand is a current challenge among many of our clad-related fabrication customers, although they also are reporting strong quoting activity from many of the industrial end markets we serve.  While the timing of improved order flow remains difficult to predict, we are cautiously optimistic that recent quoting volume will result in increased bookings.  We also are very confident that NobelClad is well positioned to address this anticipated improvement in demand.”

Guidance

Rick Santa, senior vice president, said management has maintained its prior 2014 financial guidance of revenue that is expected to be flat to up 4% versus the $209.6 million reported in 2013, and gross margins in the range of 29% to 31% versus the 28% reported in 2013.  The Company’s blended effective tax rate for fiscal 2014 is expected to range from 29% to 30% based on projected pre-tax income.

For the second quarter, management anticipates sales will be down 5% to 7% from the $57.9 million reported in last year’s second quarter, but up 12% to 14% sequentially from the $48.0 million reported in this year’s first quarter.  Second quarter gross margin is expected to be in a range of 29% to 30% versus the 30% reported in last year’s second quarter.

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. As a result, internal management reports used during monthly operating reviews feature the adjusted EBITDA. In addition, during 2014 DMC management incentive awards will be based, in part, on the amount of EBITDA achieved during the year.  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.
