DYNAMIC MATERIALS REPORTS FOURTH QUARTER FINANCIAL RESULTS

BOULDER, Colo. — February 25, 2013 — Dynamic Materials Corporation (DMC) (Nasdaq: BOOM), today reported financial results for its fourth quarter and full fiscal year ended December 31, 2013.

Fourth quarter sales were $51.2 million, down 3% from $52.5 million in the prior year fourth quarter, and a sequential decline of 6% versus $54.3 million in the third quarter.  The results were below management’s forecasts due largely to an unanticipated, short-term decline in sales at the Company’s oilfield products business, DynaEnergetics, which saw several customers in North America curtail operations during the last half of the quarter.

Fourth quarter gross margin was 26% versus the 31% reported in both the 2012 fourth quarter and 2013 third quarter.  The decline was attributable primarily to changes in product mix at DynaEnergetics and at DMC’s explosion welding businesses, NobelClad.

Operating income was $1.3 million, down from $4.5 million in the 2012 fourth quarter and $5.5 million in the third quarter.  The decline relates to the lower consolidated sales and gross margin results, as well as a $756,000 impairment charge associated with an information systems project at DynaEnergetics’ operations in Russia and Kazakhstan.

Net income in the fourth quarter was $278,000, or $0.02 per diluted share, down from net income of $2.9 million, or $0.21 per diluted share, in the year-ago fourth quarter, and $3.6 million, or $0.26 per diluted share, in the third quarter.

Fourth quarter adjusted EBITDA was $5.7 million, down from $9.1 million in the fourth quarter last year and $9.2 million 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.

NobelClad

NobelClad reported sales of $29.4 million, down from $30.7 million in the fourth quarter last year.  Operating income was $3.8 million versus $4.3 million in the 2012 fourth quarter.  Adjusted EBITDA was $5.5 million, down from $5.7 million in the comparable prior-year quarter.  NobelClad closed the quarter

with an order backlog of $36.9 million, down from $42.9 million at the end of the third quarter.

DynaEnergetics

Sales at DynaEnergetics were $19.9 million, up from $19.5 million in last year’s fourth quarter.  The business reported an operating loss of $748,000 versus operating income of $2.2 million, in the 2012 fourth quarter.  The change from operating income to operating loss resulted primarily from the previously mentioned negative change in product mix and information system impairment charge, as well as start up costs for DynaEnergetics new shaped charge facility in Blum, Texas.  Adjusted EBITDA was $1.1 million, versus $3.6 million in the comparable prior-year quarter.

AMK Technical Services

AMK Technical Services reported fourth quarter sales of $1.8 million, down from $2.4 million in the 2012 fourth quarter.  The decline principally relates to the previously discussed wind down of work on a large, long-term ground power project that accounted for a significant portion of AMK’s historical ground power revenues. Operating income was $79,000 versus $461,000 in the 2012 fourth quarter, while adjusted EBITDA was $278,000 compared with $610,000.

Full-Year Results

Consolidated sales in 2013 increased to $209.6 million from $201.6 million in 2012.  Gross margin was 28% versus 30% in the prior year.  Operating income, which reflects certain non-recurring items including a total of $1.8 million in inventory reserve adjustments, the previously mentioned $756,000 in asset impairment expenses and $3.0 million in expenses associated with management retirements, decreased to $11.7 million from $17.4 million in 2012.  Excluding these one-time charges, operating income would have been flat versus 2012.

Net income, which reflects a $914,000 first quarter tax benefit, was $7.5 million, or $0.54 per diluted share, down from $11.7 million, or $0.87 per diluted share, in 2012.  Adjusted EBITDA declined to $27.9 million from $33.6 million in the prior year.

Cash flow from operations increased 60% to $33.0 million from $20.6 million during 2012.   The increase was principally due to a $15.3 million positive change in net working capital, which offset a $4.1 million decrease in net income.  After investing $17.6 million in capital expenditures during 2013, DMC also achieved full-year free cash flow of $15.4 million versus $4.9 million in 2012.

At December 31, 2013, DMC had cash and cash equivalents of $10.6 million, working capital of $67.6 million and a current ratio of 3.2:1.  The Company closed the year with net debt of $18.7 million, a 39% reduction from $30.6 million at the end 2012.

NobelClad reported full-year sales of $118.4 million, up from $115.3 million in 2012.   Year-over-year operating income declined to $17.1 million from $17.4 million, while adjusted EBITDA increased to $23.2 million from $23.0 million in the prior year.

Full-year sales at DynaEnergetics increased to $83.7 million from $77.4 million in 2012.  The segment reported full-year operating income of $4.8 million, down from $7.0 million in the comparable prior-year period.  Adjusted EBITDA declined to $10.9 million from $12.7 million in the year-ago period.

AMK Technical Services recorded full-year sales of $7.5 million, down from $8.8 million in 2012. Operating income was $376,000 versus $925,000 in the prior year, while adjusted EBITDA was $1.0 million versus $1.5 million.

Management Commentary

Kevin Longe, president and CEO, said although DynaEnergetics saw several oil and gas customers in the U.S. and Canada rein in spending at the end of the calendar year, the business has seen a significant upturn in sales activity during the first quarter.  “Particularly notable is a recent $6.3 million purchase commitment from one of our largest U.S. oilfield products customers.  The agreement relates to DynaEnergetics’ new DynaSelect offering, and when fully delivered later this year, will represent the single largest order in DynaEnergetics’ history.”

The DynaSelect system was introduced early in 2013 as DynaEnergetics’ next-generation, safe and selective perforating system for well completion operations.  DynaSelect integrates advanced switch and detonator technologies into a single system, reducing operator set-up times while also improving reliability and safety. The system is radio frequency (RF), stray voltage and stray current safe, and incorporates advanced software controls that enable the firing of up to 20 perforating guns in a single run, while also allowing for simultaneous pumpdown and well fracturing operations.

Longe said ongoing structural improvements and personnel additions are being made at DynaEnergetics as part of a comprehensive program to position the business for strong, sustained growth.  “Our current efforts include everything from improved customer focus and market outreach to enhanced supply chain management, product management and financial reporting.”

In an effort to streamline DMC’s overall operational structure, Longe said management has begun a process in 2014 to merge AMK Technical Services into the DynaEnergetics business segment.  “With AMK’s increased focus on the oil and gas sector, we believe it will more effectively operate as part of our oilfield products business.  AMK will maintain its strong brand and will continue to serve its customers in the oil and gas, ground power and aerospace sectors.  In addition, it will perform specialized welding and machining services on select DynaEnergetics components.”  AMK’s financial results will be incorporated within the DynaEnergetics business segment by the first quarter of 2014.

Longe added that although recent booking activity at NobelClad has been disappointing, the business remains on very solid footing and is poised to address a long-anticipated increase in capital spending within several industrial processing industries, including upstream oil and gas, refining and chemical processing.  “These sectors continue to generate steady quoting activity, and we are optimistic this will result in a meaningful expansion of NobelClad’s order backlog during 2014.”

Longe concluded, “We made critical improvements to our operations, management teams and corporate infrastructure during 2013, and those enhancements will continue in the coming year.  Our primary objectives during 2014 will be organic growth through geographic expansion, market share gains and development of new products and technologies.

“We also will begin to more actively explore external growth opportunities.  DMC has a track record of acquiring and integrating businesses, and we will continue to evaluate transaction opportunities in niche

sectors of the industrial, infrastructure and energy markets.  Within the coming months, senior vice president and chief financial officer Rick Santa will assume a new role dedicated to the pursuit of business expansion and M&A opportunities.  Rick has managed the acquisitions of several businesses during his nearly two decades with DMC, and he clearly brings important expertise and institutional knowledge to this new role.  Rick will be supported by a talented internal team that includes a seasoned business strategist and financial analyst.  As he directs his focus on this new position, Rick also has begun working with me to search for, and appoint, a new chief financial officer.”

Guidance

In addressing DMC’s 2014 financial forecasts, Santa said, “We expect 2014 will be another year of sales growth for DynaEnergetics.   We also expect order volume at NobelClad could gain momentum during the year.  However, given the decline in NobelClad’s 2013 year-end order backlog, as well as the limited visibility we have on the timing of expected bookings improvements, we are currently projecting that 2014 consolidated revenue will be flat to up 4% versus the $209.6 million we reported in 2013.  We are anticipating an improvement in full-year product mix which is expected to result in gross margins improving to a range of 29% to 31% from the 28% we 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 first quarter, management anticipates sales will be in a range of 4% to 6% above sales of $46.3 million reported in the first quarter of 2013.  Gross margin is expected to be in a range of 27% to 28%.

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.
