FINANCIAL REVIEW - Fourth Quarter - Net sales totaled $142.0 million for the fourth quarter ended September 30, 2015, slightly lower than in the fourth quarter of fiscal year 2014.

RSTI net income amounted to $14.8 million, or 10% of net sales, compared to $12.0 million, or 8% of net sales, in the comparable quarter in the prior year. The diluted earnings per share was $0.52 for the quarter based upon 28.3 million weighted-average common shares outstanding, compared to the diluted earnings per share of $0.43 based upon 28.1 million weighted-average common shares outstanding for the same period last fiscal year. SG&A expenses of $24.2 million represented 17% of net sales and decreased by $2.9 million compared to last fiscal year's fourth quarter. Net R&D expenses decreased by $1.7 million to $9.8 million and represented 7% of net sales.

Sales of lasers for marking and micro applications decreased by 6% to $65.5 million and represented 46% of total sales. Sales of components increased by 8% to $20.9 million and represented 15% of total sales. On a geographical basis, revenues were stable in North America, totaling $28.1 million, decreased by 7% to $48.5 million in Asia, and were flat at $65.4 million in Europe during the fourth quarter of fiscal year 2015.

- Twelve Months - For the twelve months ended September 30, 2015, net sales totaled $519.6 million, a decrease of $10.5 million, or 2%, when compared to the prior fiscal year. The fluctuation of the U.S. dollar, mainly against the Euro, resulted in a decrease in net sales of $49.3 million for the twelve-month period. Gross profit for the period was $196.5 million, $7.6 million higher than in fiscal year 2014. RSTI net income for the fiscal year ended September 30, 2015, totaled $41.3 million. The diluted earnings per share was $1.46 based upon 28.3 million weighted-average common shares outstanding. Net sales of lasers for macro applications decreased by $9.3 million, or 4%, to $200.3 million and net sales of lasers for marking and micro applications decreased by $7.1 million to $243.1 million. Sales of components increased $5.9 million, or 8%, to $76.2 million compared to fiscal year 2014. On a geographical basis, net sales in North America in the twelve months period increased by 10% year-over-year and totaled $112.1 million (2014: $101.9 million). In Europe, net sales decreased by 9% to $232.9 million (2014: $256.6 million) and in Asia, net sales increased by 2% to $174.6 million (2014: $171.6 million). - Order Backlog - Order entry decreased by 9% to $128.8 million for the quarter and by 6% to $522.7 million for the fiscal year compared to the corresponding periods in fiscal year 2014. The backlog, mainly for laser products, amounted to $144.3 million as of September 30, 2015. On a constant currency basis, the ending backlog would have amounted to $157.7 million. The book-to-bill ratio for the quarter was 0.91. - Other Developments: Share Buyback - The Board of Directors yesterday authorized the Company to initiate a share buyback of up to $50 million of the Company's Common Stock, to be executed over the next eighteen months. The Company expects the purchases to be made from time to time in the open market or in privately negotiated transactions at the Company's discretion. - Outlook - Based on its strong product portfolio, the Company feels well-positioned for the new fiscal year and expects revenues for the full fiscal year 2016 to grow to $525 million to $545 million. Due to the cost reduction and efficiency program, the Company expects stronger growth at the bottom line with earnings per share in the range of $1.70 to $1.90, representing year-over-year growth of 23% at the mid-point of the range. Taking into account the Company's traditionally seasonally lower first quarter, likely to be further impacted by the ongoing adverse currency effects and slower economic environment in Asia, the Company expects sales to be in the range of $113 million to $118 million and earnings per share to be in the range of $0.19 to $0.24 for the first fiscal quarter ending December 31, 2015. The Company's first quarter and fiscal year 2016 guidance takes into account the anticipated 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, amongst other reasons, 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.
