Key Financials

Financial Highlights
With the considerable reduction in order intake during the second half of 2011, in line with expectations Q1/2012 revenues came in at EUR 42.0m for the quarter, 80% down on the EUR 205.4m a year before, and 70% lower sequentially (Q4/2011: EUR 140.1m). Gross profit decreased by 90% compared to the previous year from EUR 104.2m to EUR 10.3m and 13% sequentially (Q4/2011: EUR 11.8m).

Consequently, and as already predicted by Management in Q4/2011, Q1/2012 finished EBIT negative at EUR -18.3m, compared to EUR 74.9m in Q1/2011 and EUR -16.9m in Q4/2011.

The consolidated net result of the AIXTRON Group came in at EUR -12.3m for Q1/2012 (Q1/2011: EUR 52.3m; Q4/2011: EUR -10.9m).

Heavily influenced by fragile consumer confidence, credit tightness, reduced subsidies and ongoing customer overcapacity, the Company's order intake visibility remainslimited. The Q1/2012 order intake of EUR 31.5m was sequentially broadly in line with the Q4/2011 level of EUR 29.3m (Q1/2011: EUR 210.3m) which suggest that the current order levels may represent the trough level of the current cycle.

Despite the current market conditions, AIXTRON Management contiues to be convinced that the development of a sustainable LED lighting industry will follow this uncertaintransitory period.Set against this difficult environment, the Company remains focused on delivering further improvements to existing products and services and on acceleratingspecific strategic R&D investments focused on developing new products for future market opportunities.This strong R&D focus is reflected in the 32% year on year increase in R&D costs of EUR 16.4m in Q1/2012 (Q1/2011: EUR 12.4m) and the 12% sequential increase compared to the prior quarter(Q4/2011: EUR 14.6m), and additionally in the increased average number of 325 R&D employees in Q1/2012 compared to 316 in Q4/2011 and 252 in Q1/2011.

Management Review
Paul Hyland,President & Chief Executive Officer at AIXTRON offered the following comment on the current business and market situation: "Times are undoubtedly very tough - but we remain convinced that we have built a strong and resilient foundation to our business, designed to protect the Company in the difficult climate that the whole industry is currently operating in. Furthermore, we have significantly enhanced our existing product portfolio over the last 18 months, so that we are confident of being highly competitive in the event of a sudden upturn of demand in the market. Additionally, despite the very volatile current economic environment, we have more than just sustained our MOCVD R&D efforts, we have accelerated our investments into both next generation MOCVD products and other 'Beyond LED'products that we believe are necessary to support our longer-term ambitions."

Outlook
Unfortunately, order intake visibility has not improved to the point where AIXTRON Management can yet predict a full year revenue figure. Nevertheless, the Company still targets to remain EBIT profitable in 2012 under the current circumstances. On a more positive note; there continues to be solid evidence of emerging new LED lighting productdevelopments, increasingly proactive government engagements and clear company positioning investments.
