Thanks, Abe. Good morning, everybody. First quarter revenue increased 63% over the 2011 quarter with a gross profit improvement of 67%, primarily driven by the increased revenue across all categories, with the larger portion of revenue from higher margin print materials and improvement in gross profit margin of our on-demand parts services. This is combined with the printer mix shift towards lower gross profit margin personal, professional and production printers.
On a non-GAAP basis, our total operating expenses increased to $21.9 million but declined to 28% of revenue, reflecting a rise in compensation costs, driven by sales commissions from increased revenue and the operating cost of the newly acquired businesses. Specifically, our first quarter operating expenses included a $7.3 million increase in compensation costs, primarily from higher commissions on increased revenue and from the higher concentration of new acquisitions, and $2.4 million of acquisition, integration and restructuring costs. We expect these costs to translate to future annual cost savings of $5 million to $5.5 million, which is already reaching the level of our guidance on estimated combined revenue and cost synergies -- cost saving synergies of $5 million to $10 million. Our quarterly expenses also included a $2.1 million increase in R&D expenditures, were primarily driven by new product development and acquisition-related R&D expenses.
As a result of our strong revenue growth and expanded gross profit, we generated non-GAAP adjusted net income of $13.2 million and earned $0.25 per share, tax effective. On a GAAP basis, we earned $0.12 a share for the year -- for the quarter. Record materials and services revenue more than offset the planned printers mix shift towards our lower-priced printers on continued record demand of our personal, professional and production printers.
As a reminder, we report non-GAAP adjusted results that exclude the impact of amortization of intangibles, noncash interest expense, nonrecurring acquisition and severance expenses, stock-based compensation and any release of portions of the valuation allowance on deferred tax assets. Please note that our total depreciation costs and our senior convertible note cash interest expenses in connection with these acquisitions are appropriately included in our non-GAAP presentation. For your convenience, a reconciliation of GAAP to non-GAAP results is provided on this slide, as well as in our 10-Q filed this morning.
As mentioned previously, on a non-GAAP basis, we generated adjusted net income of $13.2 million or $0.25 a share for the quarter. The excluded items aggregated to a $7 million tax-effected adjustment to GAAP net income or $0.13 per share. We call your attention to the fact that we have $39.2 million of net operating losses remaining, of which $8.5 million are available for future release. We continue to evaluate the timing of amounts on future releases of valuation allowances as required.
Our reported tax rate for the quarter was 15% and consistent with previous guidance, we expect our cash tax rate to remain in the range of 3% to 5%, notwithstanding the fact that we expect our annualized effective tax rate for the full year 2012 to be in the range of 20% to 22%. For clarity, these rates are already reflected in our annual guidance, which I will cover in more detail shortly.
Reflecting our continued strong revenue growth, we believe that our results are consistent with our strategy to remix and diversify our revenue streams and in line with our expectations. In fact, quarterly recurring revenue amounted to 68% of our total revenues, with print materials contributing over $24 million and services exceeding $28 million. Quarterly printers revenue increased by $11.2 million, reflecting production printers revenue of $7.4 million and personal and professional printers revenue of $16.9 million, led by sales to healthcare, transportation and education customers. Personal and professional printers revenue increased 230% over the comparable quarter. And the decrease in production printers revenue reflects the impact of our continued realignment of printer price points across our entire portfolio with lower-priced printers which are capable of producing annual materials consumption comparable to our higher priced production printers. On a unit basis, production printers units increased 11% in the 2012 quarter compared to the 2011 period. And Z Corp and Vidar added $12.4 million of revenue for the quarter.
Geographically, we experienced stronger growth in North America aided in part by the acquisition of Z Corp and Vidar, which had higher revenue in North America. Despite ongoing regional economic uncertainties, we experienced sustained growth from both our European and Asia-Pacific regions, which remained at similar percentages of total revenue amidst a substantial increase in our North American revenue that also included growing on-demand parts services revenue. Sales into Germany and other European marketplaces remained strong.
For the first quarter, gross profit improved some 67% over the 2011 quarter to $38.9 million. Our gross profit margin for the quarter expanded primarily from the combined effect of expanding print materials gross profit margins some 460 basis points and continuing to expand on-demand parts gross profit margins coupled with a larger portion of revenue from print materials.
Consistent with our planned printer portfolio realignment, quarterly printer gross profit margin decreased compared to the prior period on record unit sales but was more than offset by a print materials gross profit increase of $6.9 million or 69% on our revenue increase of 58%, primarily benefiting from favorable mix towards a higher gross profit, integrated print materials and from the addition of higher margin RenShape and ZPrinter materials we acquired in the fourth quarter of 2011 and first quarter of 2012.
Our services gross
[Audio Gap]
$12.5 million included printer services, on-demand parts services and consumer solution services. Services gross profit margin expanded 220 basis points over the prior year period. As you can see, we're making steady progress towards our target gross profit margins. And over the past 8 periods, we have increased our consolidated gross profit margins from 45% up to 50% for the first quarter of this year.
And consistent with our past practices, for discussion purposes, we have rounded our results to the nearest percentage point. And as you can compute, our gross profit margin for the quarter amounted to 49.9%. And going forward, as our business has increased in size substantially, we plan to present our results to the 0.1%.
Our gross profit margin progressive trend displayed on this chart supports our expectation that in periods of higher acquisition concentration, we gave up some margin ground, but we were quickly able to recover and resume our margin expansion trend in the following period.
We generated $15.8 million of cash from operations in the first quarter of 2012. We ended the quarter with $60 million of cash, which was a decrease of $119.1 million since the end of 2011. But on January 3, we paid $140.3 million for the acquisition costs of Z Corp and Vidar. Excluding the senior convertible notes proceeds from the cash balance at the end of 2011, cash increased $26.3 million since the end of 2011. And while we accrue interest expense each quarter for the senior convertible notes, cash interest is only paid semiannually in June and December. And although we expect to continue to report strong cash generation from operations, the quarterly amounts may fluctuate from period to period.
Working capital decreased by $113.4 million, primarily due to the decrease in cash, a $9.9 million increase in accounts receivable from higher revenue and a $9.6 million increase in inventory, primarily due to the addition of Z Corp -- ZPrinter and Vidar inventory to support their ongoing business and the timing of inventory purchases while accounts payable increased by $7.2 million due to additional payables acquired with Z Corp and Vidar and the timing of vendor payments.
And based on our performance to date, we reaffirm our 2012 guidance that we previously announced. As a reminder, management expects revenue to be in the range of $330 million to $360 million, inclusive of the recently completed Z Corp and Vidar acquisitions, and non-GAAP adjusted earnings per share to be in the range of $1 to $1.25 per share. Management believes that these ranges correspond to adjusted net income between 16% of revenue and 18% of revenue, which depicts earnings power expansion potential in the range of 25% to 55% over our 2011 non-GAAP adjusted results reflecting our expected continued P&L leverage consistent with our long-term targets.
Our non-GAAP adjusted earnings estimate is fully tax effected. It includes management's anticipated incremental expenditures related to Cubify and expected litigation costs as we understand them. It also includes all planned restructuring and other costs in connection with the integration of our recent acquisitions, which we substantially completed during the first quarter of 2012. As a reminder, our non-GAAP earnings exclude acquisitions and severance expenses, noncash interest related to our outstanding senior convertible notes, noncash stock-based compensation expenses, intangibles amortization, and any release of the valuation allowance on our deferred tax assets. I'd also like to remind you that this guidance is based on current plans and assumptions, subject to risks and uncertainties, more fully described in the company's reports filed with the SEC.
And that concludes my comments. Abe?
