Rockwood Reports First Quarter 2013 Results

Quarter Highlights

·Adjusted EBITDA - $168 million versus $235 million primarily attributable to weak TiO2 Pigments performance

·Adjusted EPS - $0.68 per share versus $1.23 per share

Princeton, New Jersey; April 30, 2013 — Rockwood Holdings, Inc. (NYSE: ROC) today reported net income of $18.9 million, or $0.24 per share for the first quarter of 2013, which included other net charges of $35.5 million, as compared to $75.8 million, or $0.94 per share for the same period in the prior year, which included other net charges of $22.9 million.

Excluding these other net charges, adjusted net income was $54.4 million, or $0.68 per share, in the first quarter of 2013 compared to $98.7 million, or $1.23 per share, for the same period in the prior year.  Quarter on quarter performance was down on weak results from Titanium Dioxide (TiO2) Pigments, and to a lesser extent, Performance Additives, which was slightly offset by improved results from Lithium and the Advanced Ceramics medical business.

Free cash flow improved to $(5.5) million in the first quarter of 2013 from $(18.7) million for the same period in the prior year largely driven by reduced working capital needs and lower capital expenditures.  Additionally, we used excess cash on hand to prepay debt ($512.4 million), purchase the 39% interest of our TiO2 Pigments venture owned by Kemira ($130.3 million), buy back shares of our common stock ($89.4 million) and pay our quarterly dividends on our common stock ($31.1 million).

Seifi Ghasemi, Chairman and Chief Executive Officer, commented, “Our Adjusted EBITDA result for the quarter, when excluding TiO2 pigments, was slightly ahead of last year and delivered a margin of 24%, aided by steady performance from our Lithium, Surface Treatment and Advanced Ceramics businesses. While the Performance Additives business was down from the prior year, we believe it should benefit over the course of 2013 given improving signs from U.S. remodeling and construction activities. Our overall first quarter Adjusted EBITDA results were negatively impacted by continued poor TiO2 pigments performance, which we expect to trough during the second quarter before turning profitable in the latter half of 2013.”

(a) The constant currency effect is the translation impact of the change in the average rate of exchange of another currency to the U.S. dollar for the applicable period as compared to the preceding period. The impact primarily relates to the conversion of the Euro to the U.S. dollar. For the three months ended March 31, 2013 and 2012, the average rate of exchange of the Euro to the U.S. dollar is $1.3199 and $1.3121, respectively.  For further details, see Appendix Table A-1.

First Quarter Segment Drivers

Lithium: Net Sales and Adjusted EBITDA increased 3.3% and 5.6%, respectively.

·Net sales and Adjusted EBITDA increased primarily from increased selling prices for most product lines, as well as higher volumes of potash. This was partially offset by lower volumes of battery products, and, to a lesser extent, butyllithium applications.

Surface Treatment: Net Sales and Adjusted EBITDA decreased 2.2% and 0.5%, respectively.

·Net sales decreased primarily due to lower volumes in Europe driven by general industrial, coil and cold forming applications. This was partially offset by higher selling prices in Europe and in the U.S. and increased volumes of automotive OEM and aerospace applications.

·Adjusted EBITDA was flat as the impact of lower volumes was offset by higher selling prices.

Performance Additives: Net Sales and Adjusted EBITDA decreased 9.9% and 7.7%, respectively.

·Net sales and Adjusted EBITDA decreased primarily due to lower volumes from North American oil and natural gas drilling, coatings applications, as well as construction in Europe.

Titanium Dioxide Pigments: Net Sales increased 21.3%, while Adjusted EBITDA decreased 88.6%.

·Net sales increased from higher volumes, driven in large part by the acquisition of certain assets of crenox GmbH in July 2012. This was partially offset by lower selling prices.

3

·Adjusted EBITDA decreased primarily from lower selling prices, lower fixed cost absorption related to lower production levels to reduce inventory, and higher raw material costs (primarily slag and ilmenite).

Advanced Ceramics: Net Sales decreased 1.2%, while Adjusted EBITDA increased 0.4%.

·Net sales decreased slightly primarily from lower volumes in most applications, partially offset by higher volumes of medical ceramics.

·Adjusted EBITDA increased slightly primarily from higher volumes of medical ceramics.

Corporate and other: Net Sales decreased 3.8% and Adjusted loss before interest, taxes, depreciation and amortization decreased 8.1%.

·Net sales decreased primarily from lower volumes in our metal sulfides business.

·Adjusted loss before interest, taxes, depreciation and amortization decreased primarily from lower variable compensation costs.

Outlook

Commenting on the outlook, Mr. Ghasemi said, “In spite of a slow start to the year due to continued weak global economic conditions, we expect all of our businesses, with the exception of TiO2 Pigments, to show improved year on year Adjusted EBITDA results, particularly during the second half of 2013. We also remain very focused on optimizing free cash flows and prudent capital allocation strategies, including an expected return of capital to shareholders through dividends and share repurchases and reinvestment in our core businesses, such as growth projects for the expansion of our lithium carbonate capacity in Chile and our manufacturing facilities in Germany for the production of ceramic hip joints.”

Non-GAAP Financial Measures

This press release includes “non-GAAP financial measures,” such as, a discussion of Adjusted EBITDA, free cash flow and net income/diluted earnings per share excluding certain items. Adjusted EBITDA is not intended to be an alternative to net income as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements. All presentations of consolidated Adjusted EBITDA are calculated using the definition set forth in the Company’s senior secured credit agreement as a basis and reflects management’s interpretations thereof.  Adjusted EBITDA, which is referred to under the senior secured credit agreement as “Consolidated EBITDA,” is defined in the senior secured credit agreement as consolidated earnings (which, as defined in the senior secured credit agreement, equals income (loss) before the deduction of income taxes of Rockwood Specialties Group, Inc. and the Restricted Subsidiaries (as such term is defined in the senior secured credit agreement), excluding extraordinary items) plus certain items including interest expense, depreciation expense, amortization expense, extraordinary losses and non-recurring charges, losses on asset sales, less certain items including extraordinary gains and non-recurring gains, non-cash gains and gains on asset sales.  We use Adjusted EBITDA on a consolidated basis to assess our operating performance, to calculate performance-based cash bonuses and determine whether certain performance-based options and restricted stock units vest (as such bonuses, options and restricted stock units are tied to Adjusted EBITDA), and as a liquidity measure. In addition, we use Adjusted EBITDA to determine compliance with our debt covenants. We also use Adjusted EBITDA on a segment basis as the primary measure used by our chief operating decision maker to evaluate the ongoing performance of our business segments and reporting units. A reconciliation of net income attributable to Rockwood Holdings, Inc. shareholders to Adjusted EBITDA is contained in this press release. We strongly urge you to review the reconciliation. In addition, we discuss sales growth in terms of nominal (actual) and net change (nominal less constant currency impacts).

Free cash flow is not intended to be an alternative to cash flows from operating activities as a measure of liquidity. Our presentation of free cash flow is defined as net cash from operating activities of continuing operations, less capital expenditures, net of proceeds from government grants received, and other items (including, among others, the cash impact of adjustments made to Adjusted EBITDA under our senior secured credit agreement). Management believes that free cash flow is meaningful to investors because it provides an additional measure of liquidity. However, a limitation of free cash flow is that it does not represent the total increase or decrease in cash during the period. An additional limitation associated with the use of this measure is that the term “free cash flow” does not have a standardized meaning. Therefore, other companies may use the same or a similarly named measure but exclude different items or use different computations, which may provide investors a comparable view of our performance in relation to other companies. Management compensates for this limitation by presenting the most comparable GAAP measure, net cash provided by

5

operating activities of continuing operations, with free cash flow within its earnings release and by providing a reconciliation that shows and describes the adjustments made. A reconciliation of net cash provided by operating activities of continuing operations to free cash flow is provided in the accompanying tables.

Neither net income excluding certain items nor diluted earnings per share excluding certain items is intended to be an alternative for net income or diluted earnings per share. Management believes that net income and diluted earnings per share excluding certain items is meaningful to investors because it provides a view of the Company with respect to ongoing operating results. Reconciliations of these non-GAAP financial measures are included herein. These non-GAAP measures should not be viewed as an alternative to GAAP measures of performance. Furthermore, these measures may not be consistent with similar measures provided by other companies.
