SilverArrow Capital Advisors LLP Clarifies Statement Made By Rofin-Sinar Technologies Inc., Aiming For Greater Transparency

LONDON, Oct. 28, 2015 /PRNewswire/ -- SILVERARROW CAPITAL ADVISORS LLP ISSUED THE FOLLOWING OPEN LETTER TO STOCKHOLDERS OF ROFIN-SINAR TECHNOLOGIES INC. (NASDAQ: RSTI, FRANKFURT STOCK EXCHANGE, RSI) ASKING FOR TRANSPARENCY ON REPORTED NUMBERS

Dear Fellow Stockholders,

We, SilverArrow Capital Advisors LLP, one of the largest stockholders of Rofin-Sinar Technologies Inc. ("Rofin" or the "Company") were disappointed, but not surprised to see the Company's brief response to our detailed letter to the Company's stockholders dated October 8, 2015.

In our letter, we highlighted the Company's declining gross margins as evidence of inefficient operational structure. In particular, we observed that the Company's gross margins have decreased from 38.7% to 35.1% from 2010 through 2014. In its response, the Company's management characterized recent financial results as "very strong", as demonstrated by "increased . . . gross margin to nearly 40%". However, a review of the Company's recent quarterly reports suggests that, the improvements mentioned by the Board and management team are mainly based on favorable foreign exchange translation and not the result of operational improvements.

In Rofin's 2015 quarterly reports, the Company disclosed negative translation effect on sales of $35.6 million and negative effect on gross profit of $5.8 million in the nine-month period ended June 30, 2015. We believe this suggests a positive impact on Cost of Goods Sold ("COGS") of $29.8 million, which we believe is solely the result of translation effects artificially decreasing Rofin's COGS and therefore showing a higher gross margin. When viewing Rofin's gross profit on a constant currency basis, it is clear that the resulting gross margin (for the nine month period ending 30 June 2015) of 35.3% decreased slightly relative to 2014 and is not at the level reported by the company.

Below is a table that reconciles the information provided in the 10-Qs for the 9 Months 2015 versus 9 Months 2014, and 3^rd Quarter 2015 to illustrate the actual gross margin achieved on a constant currency basis:

We feel this response further demonstrates that additional transparency and disclosure is necessary to allow stockholders to fully understand the performance of Rofin. Amongst other improvements, it would be useful for Rofin to provide more detailed information on Cost of Goods Sold ("COGS"), the largest line item in the Company's expenses, and related FX translation effects, in order to let stockholders clearly see how foreign currency translation effects have impacted this figure. This increased transparency will give shareholders a clear picture of the real operational improvements in the company.

We remain fully committed to ensuring we safeguard stockholder interests and would take any steps possible to help increase long term stockholder value. As previously stated, we are open to discussing any amicable settlement with Rofin that ensures stockholders are provided with a refreshed and reinvigorated Board of Directors. If you would like to meet with us or discuss our views on the Company in greater detail, please feel free to contact D.F. King & Co., Inc., which is assisting us, toll-free at (866) 796-7186, call collect at (212) 269-5550 or email fixrofin@dfking.com. In the meantime, we urge you to reach out to the Company and reinforce our request for new independent board members.

Best regards,

Thomas Limberger Robert Schimanko
Partner and CEO Senior Advisory Board
