Thank you, Brian. First, I'll review the revenue growth that was realized in the second quarter then highlights of our quarterly financial results, our revenue, earnings and cash flow guidance for fiscal '13 and finally, our preliminary outlook for fiscal '14. I will also discuss financial disclosures we added, highlighting our strong cash earnings.
In the second quarter of fiscal '13, total revenue was $219 million, up 22%, and organic revenue growth was 6%. Every product category had organic growth.
Plasma revenue grew 7% to $69 million in the quarter, consistent with our expectations of the long-term and market growth rates of the industry. Growth in the U.S. was higher than average, while our European plasma business declined due to a shift in collections to North America. Plasma disposables revenue was up 4% year-to-date, which incorporates a slow start in Japan as a result of Japan Red Cross' Q4 fiscal '12 buy-in, and we are reaffirming our previous guidance of 4% to 6% growth in fiscal '13. We are very well positioned with customer contracts covering over 98% of our plasma business through Q3 of fiscal '15.
Blood center revenue grew organically by 2% to $55 million, with platelets and red cells each up 2% in a flat market as we are succeeding in demonstrating value to our customers. We are reaffirming guidance of 0% to 2% organic blood center growth for fiscal '13. Now remember that we will have a tough growth comparable in our platelet business later this year, resulting from the Q4 fiscal '12 buy-in by the Japan Red Cross. The Whole Blood business got off to a solid start, satisfying our primary objective of no customer disruption throughout the transition. Whole Blood revenue was $29 million, right in line with the run rate needed to realize the $135 million to $145 million of fiscal '13 whole blood revenue that we expected, and we are reaffirming this revenue guidance as well. Whole blood revenue included $20 million in North America, $6 million in Europe and European distribution markets and just under $3 million in Asia.
In our Hospital business, revenue increased 14% to $33 million in the quarter, an encouraging progression following 11% growth in the first quarter. Surgical disposables revenue was $19 million in the quarter, an increase of $2.6 million or 16%. Our installed base of surgical cell salvage devices increased by nearly 800 in fiscal '12 and by over 800 in the first half of fiscal '13, a leading indicator of future disposables revenue growth. Following the Cell Saver Elite launch, we have had 5 consecutive quarters of growth in our Surgical business. OrthoPAT disposables revenue was $8 million in the quarter, up 5%. We are on track to launch OrthoPAT Advance, our next-generation OrthoPAT device, in early fiscal '14 and expect to have OrthoPAT revenue growth for the remainder of fiscal '13.
In diagnostics, TEG disposals revenue was $7 million, growing 23% in the second quarter, with a similar 23% increase in China, where use of the TEG analyzer is growing fast in connection with interventional cardiology. We installed 230 TEG devices in the second half of fiscal '12 and a record 321 in the first half of fiscal '13. We fully expect the strong TEG disposables revenue growth to continue. So we are reaffirming our 12% to 15% fiscal '13 revenue growth guidance for our Hospital business.
Software solutions revenue was $18 million, up 5%. Sales of BloodTrack were up 19%, driven by the placement of HaemoSafe products in North America. We are reaffirming our 5% to 7% fiscal '13 revenue growth guidance for the software solutions business.
Equipment revenue was $14 million in the quarter, down 3%, reflecting the timing of shipments. Year-to-date equipment revenue was up 7%, and we continue to see strength in our Hospital business, led by TEG analyzers and surgical products in North America and emerging markets.
Geographically organic revenue was up 8% in North America, 10% in Asia, 6% in Japan, but down 2% in Europe. With the shift to plasma collections to North America, which I mentioned earlier, we expect European revenue growth to continue to be muted in the second half of fiscal '13 but expect the offsetting benefit will be seen in the North American growth rates.
Second quarter fiscal '13 gross profit was $112 million, up $20 million or 22%. Adjusted gross margin was 51%, up 10 basis points from the second quarter in fiscal '12, and organic gross margin also improved by more than 60 basis points year-over-year. Operating efficiencies more than offset the impact of lower margins from the addition of the Whole Blood business. We are making progress towards achieving our objective of long-term gross margin expansion after the drop in margins we experienced in fiscal '12.
Operating expenses were $78 million in the quarter, up $12 million or 18%. A partial quarter's Whole Blood expenditures were $8 million of the increase, including deal amortization. Operating expenses also included a full accrual of variable compensation. Now as Brian noted, the planned ramp-up in growth and infrastructure expenditures will accelerate over the remainder of the year. Please see the guidance scenarios in our website for clarity regarding expected expense levels.
Operating income was $33.6 million in the quarter, up $8.1 million. And the operating margin was 15.4%, up 120 basis points versus the second quarter of fiscal '12 and reflects both the improved gross margin and well-controlled operating expenses.
Interest expense associated with our loans was $1.4 million. Our tax rate was 27.1% in the quarter, compared with 28.1% in the second quarter of fiscal '12. Our second quarter tax rate was favorably impacted by the geographic distribution of income and increased R&D tax credits.
Adjusted earnings per share in the quarter were $0.90 versus $0.72 in fiscal '12, up 25%.
Now we ended the second quarter of fiscal '13 with $187 million of cash on hand, down $49 million during the quarter, as we utilized $60 million of cash towards the Whole Blood business acquisition in August, $5 million of -- for open market share repurchases and $12 million for integration, deal costs and other transformation activities. We generated $19 million of free cash flow in the quarter after making net investments of $26 million in capital expenditures but before funding the cash integration transformation and deal costs. Additionally, it includes the build-up of working capital not acquired with the Whole Blood business, which approximated $20 million. We continue to expect strong second half cash generation, and we are reaffirming our expectations for approximately $85 million of full year fiscal '13 free cash flow.
In late July, our Board of Directors authorized the use of up to $50 million of cash towards the repurchase of shares. We repurchased 74,300 shares in the quarter at an average price of $71.91, returning $5.3 million to our shareholders, and we see continued acquisitions and share repurchase activities along with loan repayments as our priorities for cash going forward.
In summary, we delivered continued broad-based revenue growth in Q2 and continued investing in the growth drivers of our business. So we are very well positioned for full year performance. With that, we are reaffirming full year fiscal '13 revenue and EPS guidance. We expect the pace of incremental investments to deliver a gradual, sequential improvement in earnings per share over the remainder of this fiscal year. In other words, in reaffirming our stated annual guidance, we expect adjusted earnings per share will be greater in the third quarter than in the second and greater in the fourth quarter than in the third.
I'll provide you with a brief summary of guidance for fiscal '13, unchanged from our previous guidance. As in the past, our website includes revenue and income statement scenarios which are based on the elements of guidance provided in my comments for the full year. We continue to believe fiscal '13 will be a year in which organic revenue growth will be 4% to 6%, in line with our previously indicated mid-single-digit growth expectations. Plasma is still expected to grow 4% to 6%; blood centers, 0% to 2%; hospital products, 12% to 15%; and software solutions, 5% to 7%. Whole blood revenue is expected to approximate between $135 million and $145 million in the 8 months of fiscal '13 following its acquisition, bringing our total revenue into an estimated range of $890 million to $915 million, up between 23% and 26%. Gross profit is expected to approximate $450 million to $465 million. And operating income is expected to grow 19% to 22%. And adjusted earnings per share are expected to grow between 9% and 12%, to a range of $3.30 to $3.40 per share.
Last quarter, we provided our initial insight into our outlook for fiscal '14. We are pleased with the progress we are making towards this goal. For fiscal '14, our outlook is 5% to 7% organic revenue growth and a full year's revenue from the acquired business contributing incremental revenue growth of about 8%. Thus total revenue is expected to surpass $1 billion. Our preliminary outlook for fiscal '14 adjusted earnings per share of $3.90 to $4.10, approximately 20% above the fiscal '13 expected earnings per share finish, remain unchanged.
As I've said earlier, I'm pleased with the completion of the acquisition and with the flexibility it provides to help us fund the growth priorities which we have identified. Over the past 6 years, we've been a systematic acquirer, having completed 12 deals and assembling our portfolio of blood management products and services. This culminated with the recent Whole Blood acquisition, which at $550 million is our largest ever. As we completed this transaction, a number of you suggested that we exclude deal-related amortization expense from our adjusted net earnings and from adjusted earnings per share to facilitate comparison with other companies. Given the significant impact of deal-related amortization on our EPS, we believe that such calculation has merit. It provides a view into our results that reflect our company's strong cash-generating capability. And accordingly, we have posted a supplemental table to our website showing adjusted rate results on a basis that excludes the tax-affected, deal-related amortization expense for all periods. I'll briefly recap those results.
We reported adjusted net income of $23.5 million or $0.90 per share, up 26% in the second quarter of fiscal '13. Had we excluded deal-related amortization in this year's and last year's second quarter, we would have reported adjusted net income of $27.3 million or $1.04 per share, up 33% over last year's second quarter.
Similarly, we reported adjusted net income of $37.9 million or $1.45 per share, up 6% in the first half of fiscal '13. Had we excluded deal-related amortization in this year's and last year's first 6-month periods, we would have reported adjusted net income of $43.5 million or $1.67 per share, up 12% over the last year's first half.
And lastly, we provided guidance for adjusted net income of $3.30 to $3.40 per share for fiscal '13 and the preliminary outlook for earnings per share in the range of $3.90 to $4.10 in fiscal '14. Included in these guidance ranges are approximately $22 million in fiscal '13 and $29 million in fiscal '14 of deal-related amortization, representing roughly $0.60 per share in fiscal '13 and $0.75 per share in fiscal '14, which we have not excluded.
We are providing these supplemental disclosures in order to assist you in analyzing and understanding our company's strong cash-generating capability. We will continue to provide this information going forward. Also I emphasize that we will remain disciplined in our approach to acquisitions and seek transactions that provide meaningful strategic value. These supplemental EPS disclosures are meant for enhanced transparency and not to imply any planned or imminent acquisitions. Acquisitions remain one of our stated priorities for the deployment of our cash.
Now before turning the call back over to Brian, I want to provide a brief update on our blood typing initiative. You will recall that we successfully proved the concept we sought to advance, namely the ability to type blood in just over 10 minutes with accuracy consistent with current market standards. To bring that concept to market would require both a partner and considerable expenditure. We continue to believe in the long-term value which will be delivered to blood management by this innovative approach to blood typing. However, we have decided to focus our resources at this time on the growth drivers that will help accelerate our vision of blood management in the near term. We are redirecting our spending away from blood typing to other growth initiatives with shorter and less risky investment cycles and more immediate benefits. We expect to turn our attention back to blood typing at an appropriate point in the future.
Now with that, I'll turn the call back over to Brian.
