GrafTech Reports Second Quarter 2013 Results

PARMA, Ohio-July 30, 2013 - GrafTech International Ltd. (NYSE:GTI) today announced financial results for the second quarter ended June 30, 2013.

2013 Second Quarter Review

• Net sales were $301 million, a decrease of 5 percent, versus $316 million in the second quarter of 2012.

◦ Industrial Materials revenue was $231 million, a decrease of 12 percent year-over-year.

◦ Engineered Solutions revenue was $70 million, an increase of 31 percent year-over-year.

• EBITDA^* was $40 million as compared to $67 million in the second quarter of 2012. The decline was largely driven by lower realized pricing in our Industrial Materials segment, partly offset by improved profitability in our Engineered Solutions segment.

• Net income was $4 million or $0.03 per diluted share versus $42 million or $0.29 per diluted share in the same period of the prior year. The second quarter of 2012 included a $10 million non-cash benefit of discrete tax items. Excluding the non-cash tax benefit, second quarter 2012 net income was $32 million, or $0.22 per diluted share.

• Net cash used in operating activities was $6 million versus $16 million in the second quarter of 2012.

• Net debt^* was $592 million as compared to $554 million at the end of 2012. The increase in net debt partially reflects higher inventories to support increased sales volumes in the second half of the year.

Craig Shular, Chief Executive Officer of GrafTech, commented, "Our team delivered second quarter results in line with expectations, in spite of a very challenging operating environment. Record sales in our Engineered Solutions segment and proactive cost management across the Company positively impacted these results. We expect overhead expense^** to be approximately $135 million this year as compared to $155 million in 2012."

Industrial Materials Segment

The Industrial Materials segment’s net sales were $231 million in the second quarter of 2013, as compared to $262 million in the second quarter of 2012. Net sales in the quarter decreased primarily as the result of lower graphite electrode and needle coke sales prices. Partially offsetting the impact of lower pricing was higher graphite electrode volume in the current quarter as compared to the same period in the prior year. It is important to note that the second quarter of 2012 reflected lower volumes due to the impact of customer inventory destocking initiatives.

Operating income for the Industrial Materials segment was $8 million in the second quarter of 2013, as compared to $42 million in the second quarter of 2012. The reduction in operating income is largely attributed to lower graphite electrode and needle coke pricing.

Mr. Shular commented, "The environment for our Industrial Materials products remains very difficult as steel production outside of China continues to decline year-over-year. This weakness is further exacerbated by overcapacity in the the graphite electrode industry. We will continue to leverage our low-cost business model to optimize our performance in this extremely challenging environment."

Engineered Solutions Segment

Net sales for the Engineered Solutions segment increased 31 percent to $70 million in the second quarter of 2013 compared to $53 million in the second quarter of 2012. Continued success and growth in our advanced consumer electronics product offerings drove the increase in revenue.

Operating income for the Engineered Solutions segment was $8 million in the second quarter of 2013, or twelve percent of sales. This compares to operating income of $5 million, or nine percent of sales in the same period in 2012. The increase is due to a more favorable product mix as we penetrate high-growth end markets with attractive margin profiles, offset in part by significant weakness in advanced graphite material products serving industrial sectors including transportation, chemical and metallurgical industries.

Mr. Shular commented, "Our Engineered Solutions segment achieved record sales of $70 million in the second quarter, representing nearly 25 percent of total Company revenue. Additionally, the segment delivered double-digit operating income margin performance, ramping from the first quarter of 2013, as the infrastructure investments to support growth are more effectively absorbed at

a higher revenue level. As this business continues to gain traction, it is better positioned to provide a sustainable base for diversification in tough steel cycles."

Corporate

Total company overhead expenses were $33 million versus $38 million in the second quarter of 2012. The decline in overhead was largely driven by rightsizing initiatives, reductions in discretionary expenses and lower incentive compensation expense in a difficult operating environment.

Interest expense in the quarter was $9 million, versus $5 million in the second quarter of 2012. The increase was largely driven by the issuance of the Senior Unsecured Notes in November 2012.

Outlook

In its July 9^th report , the International Monetary Fund (IMF) reduced its estimate for 2013 global GDP growth to 3.1 percent, representing the third consecutive downward revision this year. The IMF also states that global growth has not accelerated as expected and has underperformed relative to its prior expectations due to several factors including protracted recessionary conditions in Europe, weaker than anticipated economic expansion in the United States and slower growth in emerging markets.

On July 22, 2013, the World Steel Association cited that global steel production, excluding China, declined 2.7 percent in the first half of 2013 as compared to the same period in the prior year. Expectations for improvement in the second half of 2013 are waning and steel customer confidence remains low.

As a result of the above economic factors, steel data and feedback from our customers, we are reducing our targeted EBITDA range for the full year 2013 to $145 million to $165 million to reflect weaker than previously anticipated demand for our Industrial Materials products. Consequently, we are also reducing our targeted operating cash flow guidance to $110 million to $130 million to reflect the reduction in profitability and higher than previously planned inventory levels.

It is important to note that 2013 marks the final year of a third party wind-down agreement triggered by the acquisition of Seadrift Coke in which GrafTech is obliged to purchase minimum third

party needle coke quantities. Going forward, this will provide us with increased flexibility to further optimize our vertical integration with Seadrift and reduce inventories. Given the challenging operating environment, we are also reducing our targeted overhead expense^** to approximately $135 million. This compares to overhead expense^** of $155 million in 2012.

In the third quarter of 2013, we are targeting EBITDA to be in the range of $30 million to $40 million. Continued growth and improved profitability in the Engineered Solutions segment is expected to partially offset weakness in the Industrial Materials segment.

Mr. Shular concluded, "We have built an advantaged, low-cost business model supported by a solid capital structure. GrafTech is well positioned to emerge from this difficult part of the cycle stronger than we entered it."

In summary, our expectations for 2013 are as follows:

• EBITDA targeted in the range of $145 million to $165 million (previous guidance was $165 million to $195 million);

• Overhead expense (selling and administrative, and research and development expenses) of approximately $135 million (previous guidance was $140 million);

• Interest expense of approximately $37 million (previous guidance was $35 million to $40 million);

• Capital expenditures in the range of $90 million to $110 million;

• Depreciation and amortization expense of approximately $95 million (previous guidance was $90 million to $95 million);

• An effective tax rate in the range of 35 percent to 40 percent (previous guidance was 33 percent to 36 percent); and

• Cash flow from operations in the range of $110 million to $130 million (previous guidance was $150 million to $180 million).

NOTE ON EBITDA RECONCILIATION: EBITDA is a non-GAAP financial measure that GrafTech currently calculates according to the schedule above, using GAAP amounts from the Consolidated Financial Statements. GrafTech believes that EBITDA measures are generally accepted as providing useful information regarding a Company’s ability to incur and service debt. GrafTech also believes that EBITDA measures provide useful information about the productivity and cash generation potential of its ongoing businesses. Management uses EBITDA measures as well as other financial measures in connection with its decision-making activities. EBITDA measures should not be considered in isolation or as a substitute for net income (loss), cash flows from operations or other consolidated income or cash flow data prepared in accordance with GAAP. GrafTech’s method for calculating EBITDA measures may not be comparable to methods used by other companies and is not the same as the method for calculating EBITDA measures under its senior secured revolving credit facility.
