DYNAMIC MATERIALS REPORTS THIRD QUARTER FINANCIAL RESULTS

BOULDER, Colo. — October 30, 2013 — Dynamic Materials Corporation (DMC) (Nasdaq: BOOM), today reported financial results for its third quarter ended September 30, 2013.

Third quarter sales were $54.3 million, up 8% from $50.1 million in the same quarter last year, and down 6% from sales of $57.9 million in the second quarter.  Third quarter gross margin was 31%, flat versus the third quarter a year ago and up from 30% in this year’s second quarter.

Operating income increased 6% to $5.5 million from $5.2 million in last year’s third quarter, and was down 9% from $6.0 million in the second quarter.   Net income in the third quarter was $3.6 million, or $0.26 per diluted share, a 5% decline from net income of $3.8 million, or $0.28 per diluted share, in the year-ago third quarter, but up from net income of $3.4 million, or $0.25 per diluted share, in this year’s second quarter.

During the third quarter, DMC completed a comprehensive review of inventories at its oilfield products business as part of an effort to reduce inventory levels.  As a result of the review, the Company recorded a one-time expense of $1.2 million to reflect an increase in reserves for excess, slow moving and obsolete inventory. The impact of this change in estimated reserve requirements reduced earnings by $0.06 per diluted share for both the three and nine-month periods ended September 30, 2013.

Third quarter Adjusted EBITDA was $9.2 million, up 3% from $9.0 million in the third quarter last year, and down 5% from $9.7 million in the second 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, the Company’s explosive metalworking business, reported sales of $30.4 million, up 2% from $29.8 million in the third quarter last year.  Operating income was $5.6 million, an increase of 2% versus $5.5 million in the same quarter a year ago.  Adjusted EBITDA was $7.1 million, up 4% from $6.8 million in the comparable year-ago quarter.  The segment closed the quarter with an order backlog of $42.9 million versus $44.2 million at the end of the second quarter.

DynaEnergetics

Sales at DynaEnergetics, DMC’s oilfield products business, were $21.9 million, up 22% from $18.0 million in last year’s third quarter.   The increase is attributable to geographic expansion initiatives and favorable changes in product and customer mix.  Operating income was $1.7 million, up 51% versus $1.1 million in the third quarter last year, while adjusted EBITDA was $3.1 million, up 22% versus $2.6 million in the 2012 third quarter.

AMK Technical Services

AMK Technical Services, previously known as AMK Welding, reported third quarter sales of $1.9 million, down 17% from $2.3 million in last year’s third quarter.  AMK’s sales continue to reflect the wind down of a major, long-term ground power project, which accounted for a significant portion of the business’s historical ground power revenues. Operating income was $186,000 versus $386,000 in the 2012 third quarter. Adjusted EBITDA was $338,000 compared with $524,000 in last year’s third quarter.

Nine-Month Results

Sales for the nine-month period increased 6% to $158.4 million from $149.0 million during the same period a year ago. Gross margin was flat at 29%.  Operating income for the nine-month period, which includes the negative impact of the above referenced $1.2 million increase in inventory reserves, as well as $3.0 million in non-recurring expenses associated with management retirements, decreased to $10.4 million from $12.9 million in the same period last year.

Net income, which reflects a $908,000 first quarter tax benefit, was $7.2 million, or $0.52 per diluted share, down 18% from $8.8 million, or $0.65 per diluted share, in the same period a year ago.  Adjusted EBITDA declined 9% to $22.2 million from $24.5 million during the 2012 nine-month period.

Cash flow from operations through nine months increased 146% to $30.7 million from $12.5 million during the first nine months of 2012.   The increase was largely driven by a $19.0 million positive change in net working capital, which offset a $1.5 million decrease in net income.

NobelClad reported nine-month sales of $89.0 million, up 5% from $84.7 million in the comparable prior-year period.  Operating income was $13.3 million versus $13.1 million in the year-ago nine-month period, and adjusted EBITDA was $17.7 million versus $17.3 million at the nine-month mark last year.

Nine-month sales at DynaEnergetics increased 10% to $63.7 million from $57.9 million in the 2012 nine-month period.  The segment reported nine-month operating income of $5.6 million, up 15% from $4.9 million in the comparable prior-year period.  Adjusted EBITDA improved 8% to $9.8 million from $9.1 million in the year-ago period.

AMK Technical Services recorded nine-month sales of $5.7 million, down 12% from $6.4 million through the first nine months of 2012. Operating income was $296,000 versus $463,000 in the prior year’s nine-month period, while adjusted EBITDA was $749,000 versus $850,000.

Management Commentary

Kevin Longe, president and CEO, said that each of DMC’s businesses achieved important operational objectives during the third quarter.  DynaEnergetics launched commercial production at its new shaped charge facility in Blum, Texas during September, and hit key construction objectives on a third shaped charge plant being built in Tyumen, Siberia.  DynaEnergetics also has reported growing market acceptance of its new DYNAselect System, an advanced explosive initiation technology that enhances the safety and decreases the complexity of the well perforating process.

“At NobelClad, the prospective orders we referenced last quarter from the chemical industry have now been booked into backlog,” said Longe.  “In addition, our sales team has reported several additional large order opportunities have emerged from the international chemical and upstream oil and gas industries.”

Longe added, “Quoting activity has remained relatively strong, but the pace at which orders are being released by customers remains sluggish.  We are optimistic that as the global economy continues to strengthen, we will begin to see an increase in our book-to-bill ratio.  NobelClad continues to strengthen operational efficiencies, particularly at its flagship explosion welding facility in Mt. Braddock, Pennsylvania.  These improvements have allowed us to concurrently address multiple large orders with very tight delivery deadlines, while also managing our base-load production.”

Longe said that AMK Technical Services continues to pursue new revenue opportunities with current and prospective customers.  The business recently invested in a new Mazak machining center, which expands the services AMK can provide to its customers.

“As we commence the final months of fiscal 2013, we are making additional progress on the strategic objectives we established at the beginning of the year,” Longe said.  “We continue to enhance operations at the business and corporate levels and are further strengthening our leadership and support teams.  We also are expanding our presence in Asia and South America and rolling out a global re-branding campaign.  As a result of these efforts, we have a much stronger platform from which to pursue our growth plans, and are optimistic about our prospects for success in 2014 and beyond.”

Guidance

Rick Santa, senior vice president and chief financial officer, said, “In light of our year-to-date sales levels and the slight decline in NobelClad’s order backlog, we are adjusting our full year 2013 sales forecast to an anticipated growth rate of 4% to 5% versus 2012 sales.  Our prior forecast called for an increase of 6% to 8%.  However, given the year-to-date and anticipated fourth quarter product and customer mix at NobelClad and DynaEnergetics, we are elevating our full-year 2013 gross margin forecast to 29% to 30% versus the prior range of 27% to 29%.”

DMC’s blended effective tax rate for the full year 2013 is expected to be in a range of 26% to 27% (versus a previously forecasted range of 24% to 26%) based on projected pre-tax income, the previously reported $908,000 in certain tax benefits recognized in the first quarter, and the previously reported $430,000 non-recurring charge recorded in the second quarter related to a German tax settlement. Excluding the impact

of the above items, the blended effective tax rate for 2013 is projected to be in a range of 29% to 30%.

For the fourth quarter, management anticipates sales will be in a range of 2% below to 2% above sales of $52.5 million reported in the fourth of 2012.  Gross margin is expected to be in a range of 29% to 30%.

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 2013 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.
