- Six Months - For the six months ended March 31, 2015, net sales totaled $245.1 million, a decrease of $4.7 million, or 2%, over the comparable period in 2014. The strengthening of the US dollar, mainly against the Euro, resulted in a decrease in net sales of $21.3 million in the six month period. Gross profit for the period was $88.0 million, $0.4 million higher than in the same period in 2014. RSTI net income for the six-month period ended March 31, 2015, totaled $14.9 million, as compared to $6.7 million in the six-month period ended March 31, 2014. The diluted per share calculation equaled $0.53 for the six-month period based upon 28.2 million weighted-average common shares outstanding, compared to the diluted per share calculation of $0.24 based upon 28.3 million weighted-average common shares outstanding for the same period last fiscal year. Net sales of lasers for macro applications increased by $0.2 million to $96.1 million. Net sales of lasers for marking and micro applications decreased by $8.4 million, or 7%, to $113.5 million. Component sales of $35.5 million represented an increase of $3.5 million, or 11%, versus the comparable period in fiscal year 2014. On a geographical basis, net sales increased in North America in the first six months by 16% to $56.5 million (2014: $48.6 million), and by 2% in Asia to $75.8 million (2014: $74.2 million), whereas revenues in Europe decreased by 11% to $112.8 million (2014: $126.9 million). - Backlog - Order entry for the quarter increased by 11% to $141.2 million compared to the second quarter of fiscal year 2014, resulting in a backlog of $160.1 million as of March 31, 2015, mainly for laser products. As of March 31, 2015, ROFIN had a book-to-bill ratio of 1.15 for the second quarter. - Outlook - For the third quarter ending June 30, 2015, taking into account the anticipated impact of the average exchange rate, the Company expects sales to be in the range of $130 million to $135 million and earnings per share to be in the range of $0.39 to $0.42. For the fiscal year ending September 30, 2015, the Company is maintaining its sales guidance based on the current negative impact of the average exchange rates of between $515 million to $535 million, and adjusts upward its net income profitability at the mid-point of the sales range to approximately 8% of net sales. The Company's third quarter and fiscal year 2015 guidance takes into account the estimated unfavorable impact of the average exchange rate resulting mainly from the recent strengthening of the US dollar, to the extent that it continues. The majority of any such impact affects the sales level, with net income being affected to a lesser degree due to natural hedging. Actual results may differ from this forecast, including as a result of higher volatility in exchange rates, and are subject to the safe harbor statement discussed in more detail below. Non-GAAP measures should be considered in addition to, and not as a substitute for, the results prepared in accordance with GAAP. The Company believes that non-GAAP information is useful because it can enhance the understanding of its ongoing economic performance. The Company has chosen to provide this information to investors to enable them to perform comparisons of order entry and sales results.
