Thank you, Janna. Good afternoon, and thank you for joining us on today's call. I will provide financial information and John Ambroseo, our President and CEO, will provide a business overview.
As a reminder, any guidance and any statements in today's conference call pertaining to future guidance, market trends, plans, events or performance, are forward-looking statements that involve risks and uncertainties, and actual results may differ significantly. We encourage you to refer to the risk disclosures and critical accounting policies described in the company's reports on Forms 10-K, 10-Q and 8-K, as applicable and as filed from time-to-time by the company.
The full text of today's prepared remarks and trended GAAP and non-GAAP supplemental financial information will be posted on the Coherent Investor Relations website. A replay of this webcast will also been made available for approximately 90 days following the call.
Let me start by saying that we're very pleased with the fourth quarter results that we're announcing today. Revenues for the quarter were $209.6 million with corresponding pro forma earnings of $1.25 per diluted share.
The fourth quarter earnings were positively impacted by a lower tax rate, most the result of a more advantageous geographical mix of profits, adding approximately $0.10 per share to our results. Pro forma gross profit and period expenses were also favorable compared to our guidance and contributed to a record pro forma EBITDA of 22.1% for the quarter. Our fiscal 2015 pro forma EBITDA reached 19.3% and exceeded the low end of our long-term targeted range of 19% to 23%. We ended the quarter with a cash balance of $325.5 million, reflecting a quarterly cash flow from operations of approximately $56 million resulting in a record cash flow from operations for the year.
Net sales for the fourth quarter of $209.6 million increased $21.1 million or 11.2% sequentially and increased $4.3 million or 2.1% compared to the same quarter a year ago. The recent acquisitions contributed $2 million to our fourth quarter revenue compared to the guidance of $2 million to $3 million.
With respect to the revenues by major market applications, we saw double-digit sequential increase in microelectronics, single-digit increases in both our OEM components and instrumentation and scientific markets and a decrease in the materials processing market.
Microelectronics revenues grew 20.5% sequentially, which is mainly the result of shipping the third 1500 Linebeam ELA system, partially offset by lower advanced packaging applications sales. The sequential growth of 7.7% in OEM components and instrumentation is driven by the revenue of the new acquisition, more specifically in the military market, and the continuation of a strong sales in the bioinstrumentation submarket. Scientific growth of 3.2% is mainly the result of strength in Asia. Our materials processing market sequential revenue decline of 7% is not indicative of a trend considering that the fourth quarter was a very strong bookings quarter for the company.
Our shippable backlog at the end of fiscal 2015, defined as shippable within the next 12 months, is approximately $309.5 million, including $100 million or 32% flat panel display shippable bookings. The comparable shippable backlog at the end of last year was approximately $328 million, of which $136 million or 41% related to flat panel display applications.
Geographically, for the full fiscal year, Asia accounted for 52% of the company's revenues; U.S., 27%; Europe, 16%; and the rest of the world, 5%. Asia includes 2 territories with revenues greater than 10%. South Korea and Japan represent 24% and 17% of fiscal 2015 revenues, respectively.
Service revenues for the fourth quarter were approximately $64 million or 30% of sales and represent 12% growth both compared to last quarter and the same quarter last year. Fiscal 2015 service revenues increased to almost $241 million or 30% of sales compared to $234 million or 29% of sales last year. The fourth quarter flat panel display service revenues increased approximately $5 million sequentially and fiscal 2015 flat panel display service revenues grew approximately 4% year-over-year.
We had one customer in South Korea, an integrator to a large flat panel display manufacturers, who contributed more than 10% of the company's fourth quarter and year-to-date revenues.
The fourth quarter pro forma gross profits, excluding stock compensation charges, intangible amortization and the inventory step-up related to the purchase accounting was $93.6 million or 44.6% of sales, which compares to 43.5% last quarter. The sequential increase of 110 basis points was mainly the result of lower-than-expected warranty events and the resulting reduced reserve requirements coupled with improved manufacturing efficiencies.
Compared to our guidance, product mix was also more favorable mainly due to the higher-than-anticipated service revenues.
Period expenses excluding stock compensation charges, the bargain purchase accounting gain and net of the deferred compensation benefits, for which the offset is included in OIE, were 25.6% compared to a guidance of 26.5% to 27%. The lower period expenses are due in part to a lower spending run rate at the companies we recently acquired. We had originally estimated $1.5 million for 2 months of activity; our revised estimate is approximately $1.5 million for 3 months of activity. In addition, we benefited, sooner than anticipated, from the cost reduction efforts we announced last quarter. We also experienced substantially lower medical claims during the quarter compared to preceding trends.
And we move on to the balance sheet. Our cash and cash equivalents for the quarter was $325.5 million, which represents a decrease of $11.3 million compared to last quarter. During the quarter, we repurchased approximately 868,000 shares for a total of $50 million, we completed 2 acquisitions for $9.3 million and had capital expenditures of approximately $6 million. As an offset, our cash flow from operations for the quarter, at $55.6 million, was the strongest quarter we've ever seen. Higher cash flows were mainly driven by our increased earnings coupled with improved working capital metrics. Accounts receivable DSO stood at 61 days compared to 69 days last quarter and inventory turns improved from 2.8 to 3 turns. Year-to-date cash flow from operations amounted to $124.5 million, a record for the company.
Approximately $271 million or 83% of the cash balance is held internationally, mainly in Europe and about 72% of the total cash is denominated in dollars.
For the full year, we repurchased approximately 1.3 million shares for $75 million.
Capital spending for the quarter was $6 million or 2.9% of sales and year-to-date spending was $22.2 million or 2.8% of sales.
Let me move on to the guidance for the first quarter of fiscal 2016. As a reminder, our first fiscal quarter is a shorter quarter due to the many holidays and has typically resulted in revenues ranging from 2% to 12% below the fourth quarter revenue of the prior fiscal year. Accordingly, we project our first fiscal 2016 quarter revenue to range from $192 million to $198 million.
We forecast the first quarter pro forma gross profit percentage to be in the range of 42.5% to 43% of sales, which is lower than the quarter we just ended, mainly due to a higher purchase price for neon gas resulting from a supply shortage coupled with the impact of lower volumes, a less favorable mix and the diluted impact of the recently acquired businesses. In the meantime, the neon supply shortage has eased and we expect to see margin improvement starting in the third quarter of fiscal 2016. Pro forma margin, as usually, excludes intangible amortization and stock compensation costs.
We anticipate the first quarter pro forma period expenses to increase to approximately 27.5% to 28% of sales, mainly as a result of lower revenues. The sequential increase are primarily due to an extra month of spending for our acquisitions and the assumption of a normalized level of medical claims from our self-insured plan. These expenses are partially offset by the impact of the cost reductions we announced last quarter. And again, the guidance excludes intangible amortization and stock compensation costs.
Other income and expense is estimated to be immaterial. We do not include transaction gains and losses related to future changes in foreign exchange rates in our guidance.
We project our pro forma tax rate to be approximately 30% for the fiscal year. The increase compared to fiscal 2015 is a result of completing our tax exemption status in South Korea during fiscal 2016, a less favorable profit distribution and no reinstatement of the federal R&D tax credit.
We forecast our full fiscal 2015 capital spending to be approximately 4% to 5% of sales. And this includes projects that were postponed from fiscal 2015 into fiscal 2016 as well as additional building expansion and improvement projects.
We are assuming a weighted outstanding shares of 24.3 million for the first quarter.
I will now turn over the call to John Ambroseo, our President and CEO.
