IFRS pro forma operating income of EUR 4.8 million (6.0% of revenues)

FY 2012 revenues at EUR 330.1 million,
IFRS pro forma operating income of EUR 21.8 million (6.6% of revenues)

Martinsried/Munich, Germany. February 28, 2013. ADVA Optical Networking announced Q4 and audited
full-year 2012 financial results for the period ended December 31, 2012, and prepared in
accordance with International Financial Reporting Standards (IFRS).

Q4 2012 IFRS FINANCIAL RESULTS

Revenues totaled EUR 80.3 million in Q4 2012 and were in the upper half of guidance of between EUR
77 million and EUR 82 million. Revenues are down 3.8% vs. Q4 2011 at EUR 83.4 million and down
2.4% vs. Q3 2012 at EUR 82.3 million. IFRS pro forma operating income, excluding stock-based
compensation and amortization & impairment of goodwill & acquisition-related intangible assets,
amounted to EUR 4.8 million in Q4 2012 or 6.0% of revenues, at the upper end of guidance of
between 2% and 6% of revenues. This compares to Q4 2011 IFRS pro forma operating income of EUR 7.4
million or 8.9% of revenues, and to Q3 2012 IFRS pro forma operating income of EUR 5.6 million or
6.8% of revenues. These developments are largely due to lower revenues and increased selling and
marketing expenses.

The IFRS operating income in Q4 2012 was EUR 4.3 million, down from EUR 6.7 million in Q4 2011.
This is due to the above-mentioned reasons for lower pro forma operating income.

The IFRS net income in Q4 2012 amounted to EUR 4.1 million after EUR 8.7 million in Q4 2011.
Beyond the reduced operating income, net foreign currency exchange losses of EUR 0.1 million in Q4
2012 after gains of EUR 1.9 million in Q4 2011 contributed to this decrease. Basic and diluted
IFRS net earnings per share were EUR 0.09 and EUR 0.08, respectively, down from EUR 0.18 each in
Q4 2011.

FULL-YEAR 2012 IFRS FINANCIAL RESULTS
Driven by increased Ethernet access business, revenues rose to a record high of EUR 330.1 million
in 2012, 6.2% above the EUR 310.9 million reported in 2011. IFRS pro forma operating income
increased from EUR 17.3 million or 5.6% of revenues in 2011 to EUR 21.8 million or 6.6% of
revenues in 2012. This improvement is largely due to revenue and gross margin growth.

2012 IFRS operating income at EUR 18.8 million also increased significantly from EUR 13.2 million
in 2011. The main reason for this positive development is the above-mentioned increase in pro
forma operating income and a reduction in amortization of intangible assets from acquisitions from
EUR 2.5 million in 2011 to EUR 1.6 million in 2012.

Finally, IFRS net income amounted to EUR 16.7 million in 2012, slightly down vs. EUR 16.9 million
in 2011. The positive operating income development was mostly compensated by income tax expenses
of EUR 1.8 million after income tax benefits of EUR 2.9 million in 2011. Furthermore, net foreign
currency exchange gains of EUR 0.8 million in 2012 were lower than the EUR 2.3 million recorded in
2011. Basic and diluted IFRS net earnings per share were EUR 0.35 and EUR 0.34 in 2012, slightly
down from EUR 0.36 and EUR 0.35, respectively, in 2011.

Q1 2013 OUTLOOK
