Bill Sullivan - President & CEO
Thanks, Alicia, and hello, everyone. Agilent had Q4 orders of $1.75 billion, up 4% year-over-year. Q4 revenues of $1.73 billion were up 9% year-over-year. The revenues were slightly below our guidance due to currency. Non-GAAP EPS was $0.84 per share, above our guidance, and operating margin was 21.6%.
Agilent's operational performance was the best in its history. Electronic Measurement had Q4 revenues of $855 million, up 12% over last year. Communications growth of 20% was driven by wireless manufacturing. General purpose growth of 8% was driven by industrial markets, while aerospace and defense grew 2%. Quarterly operating margin was above 24%, another record high for the business.
Chemical Analysis saw revenue growth of 4% over last year to $405 million. Petrochemical grew 8% with strong GC sales to industrial accounts. Food was up 5%, driven primarily by China. Forensics and environmental revenues were up 1%. Q4 operating margin was 24%.
Life Science revenues of $471 million were up 9% over last year. Strong demand from applied markets led the growth. Pharma grew 5%. Academic government was up 4%. And operating margin for the quarter was 14%. In summary, our applied markets grew 9%, our core Life Science business grew 4%.
We generated $510 million of cash from operations, and ended the fiscal year with $1.4 billion in net cash. For the year, Agilent's revenue of $6.6 billion were up 21% over last year. Operating profit of $1.3 billion, 20% of revenue, was up 40%. Fiscal year 2011 was an excellent year for Agilent.
Our outlook for fiscal year 2012 is for the revenue to be $6.85 billion to $7.15 billion. Fiscal year 2012 EPS is expected to be in the range of $3 to $3.35 per share. The basis for our forecast is as follows. Today, the outlook for the worldwide gross domestic product growth is about 3.5%. We are going to take a conservative position in the Measurement market and assume that market will also grow 3.5%. Based on our geographic and product mix of our eight market segments, we believe we will have an additional 1.5% growth, and finally, the Electronic Measurement group's backlog flush will contribute 0.7%. Therefore, we will end up in the midrange of our guidance of roughly 5.7% growth for next year.
By market segment, Electronic Measurement is expected to grow 4.2%, inclusive of the anticipated reduction of backlog. Life Science and Chemical Analysis combined are expected to grow 7.1%, again resulting in our midrange growth guidance of 5.7%.
First quarter fiscal year 2012 revenue guidance is $1.65 billion to $1.67 billion, with non-GAAP earnings of $0.67 to $0.69 per share. Our revenue EPS guidance reflects the impact of the lunar holiday in the last week of January, which is the end of our fiscal quarter. We remain cautious as we enter the new year, but believe there are several excellent market opportunities. We believe communications and petrochemical markets will remain robust, along with solid opportunities in the food markets. We also see continued opportunities to increase our presence in the Life Science market. Coupled, these market opportunities with our continued investment in emerging markets, and we believe our growth expectations are realistic, barring a financial crisis.
In addition, we will continue to focus on improving gross margins in the Chemical Analysis and Life Science groups. As I have noted in the past, we are leveraging Agilent's design capability, supply chain, and low cost manufacturing capability to improve our Chemical Analysis and Life Science gross margins. While this effort will take several years, we can believe we continue to make solid progress in fiscal year 2012.
Finally, we plan to continue to invest 10% of revenue in R&D. We have a deep pipeline of new product launches in fiscal year 2012 across all of our product lines. We are committed to be the technology leader, and to maintain our number one position in customer satisfaction. Thank you for being on the call, and now I would like to turn it over to Didier.
Didier Hirsch - SVP, CFO
Thank you, Bill, and hello, everyone. I'll start by providing some additional color on our fourth-quarter results and then comment on our outlook for Q1 and the fiscal year. As in prior calls, all of my comments will refer to non-GAAP figures.
So starting with Q4 results, as Bill mentioned, we are quite pleased with Agilent's fourth-quarter results as revenues, once adjusted for currency, were in line with our guidance, and operating margin, EPS, and cash flow reached an all-time high.
Orders of $1.75 billion were up 4% from one year ago, including 2 percentage points from currency. Adjusted for currency, EMG orders declined 1%, while LSG and CAG grew 7% and 2% respectively. The regional distribution of the 2% order growth at constant currency was a combination of flat orders in the Americas, a 2% decline in Europe, a 6% decline in Japan, and 11% growth in the rest of Asia-Pacific. Revenues of $1.73 billion were up 9% from one year ago, including 2 percentage points due to currency. Adjusted for currency, EMG revenues grew 10%, LSG, 6%, and CAG, 1%. The regional distribution of the 7% revenue growth at constant currency was 6% growth in the Americas, a 1% decline in Europe, 9% growth in Japan, and 13% growth in the rest of Asia-Pacific.
Now, moving to the income statement, while currency impacts each P&L line, it has minimal impact on our operating margin performance as a result of our geographic diversification and systematic hedging program. Gross margin of 55.1% improved nearly 1 point on a sequential basis, starting to reflect Varian cost of sales synergies. Expenses were very well controlled, and only increased 1% year-over-year. Q4 operating margin of 21.6% was another all-time high for Agilent. Operating margin improved 140 basis points from last quarter, and was up 250 basis points year-over-year.
By segment, EMG's operating margin reached a record 24.4%. CAG's operating margin of 24% was up 340 basis points sequentially, and LSG's operating margin of 14.4% was up 120 basis points sequentially. Finally, Agilent's year-over-year operating margin incremental of 48% was way above the secular 30% to 40% range. While the world economic outlook remains uncertain, we continue to maintain the discipline of our operating model, as evidenced by this quarter's financial results. Non-GAAP net income of $296 million, or $0.84 per share compares to $228 million, and $0.65 per share one year ago, an increase of approximately 30% year-over-year. Both quarterly earnings per share of $0.84 and full year EPS of $2.95 are historic highs for Agilent.
Now, turning to the cash flow and our cash flow statement, total quarterly cash generated from operations was $510 million, an increase of $137 million compared to the same period last year. During the quarter, we received $5 million from employee stock programs and repurchased $35 million worth of shares, for a net share buyback of $30 million. This year, we invested $497 million in gross share repurchases, or $193 million net of stock issuances from employee stock plans. Our net cash position at the end of October was $1.4 billion, an increase of $426 million from one quarter ago, and $829 million higher than Q4 last year.
Now, turning to the guidance for fiscal year 2012. Given our solid Q4 performance and reflecting our confidence in Agilent's competitive position and operating model, we are projecting a fiscal year 2012 revenue range of $6.85 billion to $7.15 billion. The corresponding EPS range is $3.00 to $3.35 based on 355 million diluted shares, and no change in the tax rate. You will note that the midpoint of our revenue guidance, $7 billion, translates into 5.7% year-over-year growth. The midpoint of our EPS guidance, at $3.18 translates into 8% growth over our fiscal year 2011 EPS of $2.95, which is consistent with a year-over-year operating margin incremental of 31%.
As you update your model for fiscal year 2012, please consider the following. First, annual salary increases will be effective December 1, 2011. Second, stock-based compensation will be about $84 million compared to $73 million in fiscal year 2011. As we front load the recognition of stock-based compensation, the Q1 expense will be about $31 million. Third, depreciation is projected to be $160 million for the fiscal year. Fourth, net interest expense is forecasted at $83 million, and other income of $16 million. Fifth, we expect operating cash flow of approximately $1.1 billion, and capital expenditures of about $180 million, which yields free cash flow of approximately $900 million. And finally, we distribute our variable and incentive pay in Q1 and Q3; hence, Q2 and Q4 are seasonally higher cash flow quarters.
Now moving to the guidance for our first quarter, we expect Q1 revenues of $1.65 billion to $1.67 billion, and EPS of $0.67 to $0.69. At midpoint, year-over-year revenue growth will be 9%, while the midpoint of our EPS guidance corresponds to a year-over-year EPS growth of 13%. As a reminder, we typically see EPS decline materially from Q4 to Q1, because of the impact of the December salary increase, front-loading of stock-based compensation, and the increase in payroll taxes due to the disbursement of the variable and incentive pay of the previous semester. With that, I'll turn it over to Alicia for the Q&A.
Alicia Rodriguez - VP - IR
Thank you, Didier. Keith, will you please give the instructions for the Q&A?
Operator
(Operator Instructions). Your first question is from the line of Jon Wood with Jefferies. Please proceed.
Brandon Couillard - Analyst
It's actually Brandon Couillard in for John tonight. Bill, can you remind us when you'll have the lateral to potentially repatriate some cash back into the US, and any changes to your capital allocation strategy as we look out to next year?
Bill Sullivan - President & CEO
Again, we have no changes to our capital allocation. Our number one focus is continuing to invest in our business. Those types of business have to create value for our shareholders. Secondly, and we have a long history of returning cash back to our shareholders through stock purchase in particular.
As Didier's outlined in the past, next year, you should target roughly a repatriation of about $500 million. Unfortunately, it's at the very end of the calendar year. So, until there is a change in Congress, the likelihood of substantial repatriation in FY 2012 is low.
Brandon Couillard - Analyst
Thanks. And then if Nick and/or Mike are there, could you give us a little more color on the organic revenue growth expectations between the Chemical Analysis business and Life Science side? And how should we think about pharma versus biotech going into next year? Do you still anticipate, I guess, some replacement cycle demand vitality next year?
Nick Roelofs - SVP & Pres of Life Sciences Group
Let me take the second question first, which is the pharma and biotech comment. So, yes, we still see some strength in terms of a technology upgrade replacement cycle. Geographically, that strength is as good or better in emerging markets, where we see large pharma new sites, as it is in the existing markets. But that's a pretty strong cycle for us through 2012. And as I've said before, we get nervous around 2013. But for 2012 right now, that looks pretty good throughout the year. So, that's the first part of the question.
Mike McMullen - SVP & Pres of Chemical Analysis Group
And Bill, the next comments relative to the Chemical Analysis space, we're still anticipating continued strength in the replacement market in the chemical and energy space, as well as the emerging markets will continue to be a source of growth of business, as Bill highlighted earlier, in the area of food and particularly in environmental in China.
Brandon Couillard - Analyst
Thank you.
Operator
Your next question's from the line of Ross Muken with Deutsche Bank. Please proceed.
Ross Muken - Analyst
So, as we think about sort of pacing of the quarter, particularly in EMG, can you give a little color on sort of how the order trends played out, sort of month by month, and to the degree you felt comfortable with the trajectory into the first quarter of your 2012 guidance?
Bill Sullivan - President & CEO
Ron?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
Sure. Communications market continues to be very strong, as we show 20% growth in revenue, and we also had very strong growth in wireless manufacturing. So, the orders were relatively linear through the quarter. There wasn't a huge hockey stick in the last month of the fiscal year, as we've seen in the past. But the guidance that we've given is very consistent with what we are seeing.
Ross Muken - Analyst
Okay, and maybe just quickly on the communication front, there was a number of the large, the large telco players that recently were out making positive commentary on 4GLT spending for fiscal year 2012 in terms of pushing forward some investments. Is that sort of the demand we're seeing in the context of the Com business being so strong relative to the rest? And I guess in terms of historical reference in times when that's happened, has the spend continued regardless of the economic environment?
Bill Sullivan - President & CEO
Well, each company is in a different position and they may go, they may take different approaches. But we are seeing a race towards 4G. So, first of all, we're seeing SmartPhone growth in 3G cell phones, and that continues.
In 4G, they are starting to roll out where more of the investment, though, is in the base station side. We did see a bit of a pause in base station build out in Europe, but other than that, we've seen very strong growth in the overall SmartPhone market that has driven, that has driven our overall communications business.
Ross Muken - Analyst
Great, and I'm sorry to be a question hog here, but one last one. Just in terms of CAG, we've seen a pretty decent deceleration there in demand. Obviously we could see from a segment perspective, some of the culprits. I guess as you think about whether the product refresh, or it's some of the other customer-focused segments, what's the goal there, to kind of get growth back to a normalized trend? Or, is it more working through some tough comps?
Mike McMullen - SVP & Pres of Chemical Analysis Group
You answered your own question. This is Mike. We did have tough comps relative to 2010. We had a big bulge in Americas business last year, as well as the substitution effect of some divested products. But we're very confident about the go-forward look for the business as we move into the first half.
And it's really centered around two major themes. One is this emerging market focus that Bill alluded to earlier. Growth was very strong in emerging markets, again, led by Asia in the fourth quarter. Our book to bill actually was over 1, despite sequential growth in orders in revenue. And we're really going to benefit from the strength of a number of new product offerings, as I mentioned in the last call.
We had new offerings of both spectroscopy in the EMS spec area and we're now starting to take orders for those and you'll see that flowing into revenue in the first half of next year. We're very confident about where we're heading in the early part of 2012.
Ross Muken - Analyst
Great. Thanks, Mike.
Operator
Your next question's from the line of William Stein with Credit Suisse. Please proceed.
William Stein - Analyst
Great, thanks. I'm hoping you could talk a little bit about the Varian integration. I think the years lapped and I know you're on the path to integrating these businesses fully, and I would like you to talk a little bit if you can about the cost savings from the integration, where you are in that process.
Bill Sullivan - President & CEO
As you know, we've been very clear that in terms of what we would say by leveraging the infrastructure of the company, leveraging our IT systems, leveraging our financial systems, that we are able to take $35 million of costs out, and that has been completed. The other additional $35 million is around cost of sales.
And in that area, both Mike and Nick are working very hard to redesign products, get new products out, leveraging the supply chain within Agilent. And of course moving products to the appropriate locations. We have set up some of these spectroscopy product lines, they're now up and running in Penang, and the teams are working very, very hard.
This is going to be a multi-year effort, but as I said in my comments, I believe we're going to continue to see measurable improvement as we go into next year. If you look at the gross margin difference between LS and CA versus EMG, we have a lot of opportunity moving forward, but we want to do it right.
It's easy to tear the costs out to begin with, but what we want to do is make sure that the products that we are developing are highly competitive and we will go through the design cycle to ensure that we have very high quality, product-leading platforms, and of course low cost manufacturing.
William Stein - Analyst
Great, that's helpful.
Mike McMullen - SVP & Pres of Chemical Analysis Group
Bill, this is Mike. I thought I would build on your comments. I think as Didier mentioned earlier, we're starting to see some traction in the third to fourth quarter as the gross margins saw pretty good sequential improvement. I think you're starting to see some earlier stage effects of the Varian integration synergies.
William Stein - Analyst
That's very helpful, thanks. And, Bill or whomever wants to chime in, perhaps, can you talk a little bit about emerging market strength outside of China? Be very interested in developments in the Russia, Brazil, et cetera.
Bill Sullivan - President & CEO
Just roughly, in India, our growth rate was over 30%, similar to China. Brazil was up 70%, Russia was up 40%.
William Stein - Analyst
Great, thank you.
Bill Sullivan - President & CEO
Okay, thank you.
Operator
Your next question is from the line of Jon Groberg with Macquarie. Please proceed.
Jonathan Groberg - Analyst
Hi, thanks for taking the questions. Just two questions for me. Bill, what's your outlook for the aerospace and defense and then the government end markets and the LSG space for 2012?
Bill Sullivan - President & CEO
I'll make a comment again, and then Ron, feel free to chime in, in terms of the aerospace and Nick in terms of the overall government, where a different position given our market share tends to be low. But we're assuming, as we move forward, aerospace and defense is going to be flat.
We could get 2% growth this year. We do have opportunities outside of the United States, but the model that we are, we have built in our growth has really conservatively looked at growth opportunities in some of these segments and then looked at where the opportunities are, such as communications, such as petrochemical, such as the mix into emerging markets, and that's how we derive the range of outcome, or likely outcome in fiscal year 2012, barring another financial crisis.
But again, we are taking a conservative position, given where we are. Even if there's not a resolution in the US, the impact on aerospace and defense, particularly the DoD, won't happen till 2013. So, my overall guess is that the market in 2012 will be flat in the US. Ron, any additional comments? Nick, comment?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
That's exactly what we're seeing in Electronic Measurement, business that's roughly flat. We feel very competitive about where we are, but we're seeing programs push out, as people are a little unsure on spending. But as Bill has mentioned, about 30%, about 33% of our business is outside of the US, and that business, depending on where it is, may or may not be different.
Nick Roelofs - SVP & Pres of Life Sciences Group
And on the academic government, let me do a couple slices for you. First of all, we see that as a pretty healthy mid single-digit market on a worldwide basis. We're going to see real strength from the emerging markets, although it's a small number.
Europe looks positive, believe it or not, in academic government. And the Jeffers team did an analysis of about a 5% growth rate there. That's consistent with our analysis for Europe. So, we think that's what the market will do.
The US is a real problem, and so the question is what does that look like? NSF budget's down about 2.4%. NIH budget, although it has not fully passed through Congress, looks like it will be slightly up. But right now, we're on continuing resolution.
But to give you an effect of how small an impact that is to us, we had a significant double-digit down in North American academic government and still had strong numbers, and that's for Q4. So, we're not too worried, but it could be a rough year for academic government in the US.
Jonathan Groberg - Analyst
So, just to clarify, Nick, in this last fourth quarter in the US, you were down strong double digits?
Nick Roelofs - SVP & Pres of Life Sciences Group
Let's put it in the teens, down teens.
Jonathan Groberg - Analyst
Okay. That's helpful. And then if you look at the EMG business, you say orders were down, but sounds like you still have backlog that you're going to burn off here. I guess how are you thinking about that business pacing in 2012, given -- I've never seen you give such detailed guidance, Bill, with 4.2% and 7.1% outlooks.
Bill Sullivan - President & CEO
Well, needless to say, we've done a lot of work, trying to figure out what the likely outcome is, given the overall political cloud over Europe and the US. And the backlog, given if you go back and you look at our backlog growth in EMG over the last year, it has been very, very substantial.
So, you have one argument saying the book-to-build is below one, so that's bad news. On the other hand, Ron's doing a great job ramping up the revenue, as we said we were going to do, putting on capacity as quickly as we can. And the underlying orders actually weren't so bad. And so it's which side of a, how do you look at the glass half-full or half-empty? Ron, why don't you make a couple comments about, at least, your thoughts as you move into 2012?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
As Bill had mentioned, we grew approximately $200 million worth of backlog last year and we've been trying to get that down. This quarter, we managed to ship or burn of about $33 million of backlog. So, we'll continue to do that, and that adds, as Bill had mentioned, about 0.7 points of growth for Agilent, or roughly 1.4 points of growth this upcoming year for EMG.
But the order situation is flat, but we see a dynamic environment. Some of the smaller businesses that we're in, such as little pieces that we still have left in the semiconductor market are down. The aerospace defense business is flat. But we're seeing other areas such as the industrial market grow. It grew 20% this quarter and we've seen wireless manufacturing grow over 50% during this last quarter. And communications in total grew 20%.
So it's a mixed picture, but the underlying trend of moving towards 4G and the rollout of these new technologies that we see around the world, I do not believe that is going to take a significant pause. We have seen many companies in the past put their foots on the brake when there's been an economic situation and never recover from the cycles. So, we're working very closely with the customers to make sure that we capture all the opportunity that's out there.
Bill Sullivan - President & CEO
Again, just to restate what Ron had said, in the big difference of EMG going to 2012, it's all communication. We need to continue to grow much faster than the overall market and really capitalize on the 3G opportunity, emerging markets and win in 4G. I think based on another quarter of excellent results, we are clearly performing well in the communication market.
Jonathan Groberg - Analyst
Thanks a million.
Operator
Your next question's from the line of Paul Knight with CLSA. Please proceed.
Paul Knight - Analyst
Hi, Bill. What was the China growth? Maybe I didn't hear it.
Bill Sullivan - President & CEO
Both China and India grew over 30%.
Paul Knight - Analyst
And the organic growth by each of the three divisions?
Didier Hirsch - SVP, CFO
All the growth is organic this quarter, Paul.
Paul Knight - Analyst
Okay. And are you building currency into your estimates here on fiscal year 2012 or using current status?
Didier Hirsch - SVP, CFO
Well, like every time we use the exchange rate as of the last day of the previous month, for example, Euro equals $1.40 and that's what we use for our guidance. Using those rates, currency plays very, very minimum impact on the year-over-year growth, about 1 percentage point in the first half positive and 1 percentage point in second half negative, zero for the whole year.
Paul Knight - Analyst
And then lastly, you guided, I think it was to $83 million net interest expense, which seems with your cash buildup higher than fiscal year 2011. What's that all about?
Didier Hirsch - SVP, CFO
The increase on 2011-2012 comes from the fact that in Q3 and Q4, and you will have noticed that in our cash flow statements, we unwound interest swaps on debt, so we had $65 million of cash inflows and a gain that will amortize over the remaining period of the debt. In the short-term, it also means higher interest expense. So, interest expense is moving up a little bit and along the line of what you are seeing in Q4.
Paul Knight - Analyst
Okay, thank you.
Didier Hirsch - SVP, CFO
Sure.
Operator
Your next question's from the line of Nandita Koshal with Barclays Capital. Please proceed.
Nandita Koshal - Analyst
Good afternoon. Thanks for taking the questions. Maybe I'll start with the EMG. Ron, if you could expand for us on the base case for 2012, what are you assuming in that base case what needs to happen for you to meet that mid-point goal? And then maybe a little bit on the key upside and downside risks that you foresee?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
Sure. It's all about communications. That's what we're seeing grow. That's what we continue to be very strong in, and we have a very -- we have an excellent competitive position and that's where our focus is. So, we're going to continue to focus in that area and we're assuming that market will remain moderately healthy.
Not even, we're not even assuming that there's any real inflexion point at all in that business, for the good. We are assuming the aerospace defense business will be roughly flat in this same period of time. So, you could make assessments on that. But we're very comfortable with the guidance that we have given.
Bill Sullivan - President & CEO
Just to add on that, if you just look at market growth, aerospace and defense is flat, Com is a 7%, and industrial computer is 5%. You sort of get what the guidelines we've given for Ron.
Nandita Koshal - Analyst
Thank you. And we've seen some of your large competitors on the EMG side put in place some significant restructuring programs. They have actually taken them up recently. How are you thinking about operating flexibility in that business, in case those upside, downside scenarios play out?
Bill Sullivan - President & CEO
Well, we've been working for a couple of years to have a much more variable cost structure. We reduced our head count of internal employees 3,000 people, from 11,000 to 8,000 in the 2009 and early 2010 standpoint. And as we have grown over $1 billion in the last two years, or close to 33%, we've only put in about 2% of head count growth.
So we've kept our fixed costs very low. And that has loud us to deliver this year the highest operating margin ever, the highest return on invested capital ever, and the highest gross margin ever, as well as the highest operating profit dollars ever, even including the dot-com boom.
So we're very comfortable with the structure that we put in place, and we've been very, very disciplined not to add people on the upswing, because we realize in the capital equipment market, there's a little bit of cyclicality that is in it, but the fundamental bases are strong and we've set ourselves up to have double-digit profit, even if revenue would drop significantly, which we do not expect. And on the upside, produce phenomenal incrementals like we have done in the past.
Nandita Koshal - Analyst
Okay. That's very helpful. Bill, maybe just one more. You've been investing quite aggressively on some of the Varian product lines, for instance, and [anamar.com] you put in place, one of the highest (inaudible) NMRs in the world, and trying to build Agilent strength there. How much of a drag have those investments been on margins through the past year and what do you expect in terms of benefits and growth and competitive positions for those products? Thank you.
Bill Sullivan - President & CEO
Yes, I'll have a comment on the product side Nick, and Mike made a comment, both on the spectroscopy platform, in terms of the NMR. Actually, where the biggest investment has been has been in the expense line. We are obviously working to improve the gross margins.
We've increased the research and development investments in both groups. We have expanded our service and support to address some of the customer issues that we face, again, the company just wasn't large enough to make some of the investments that were required. And so most of the drag has been the expense area.
But as you can see, our expenses have been incredibly well-controlled because we did such a good job of driving efficiencies from what would be a corporate view of the Varian expense structure. Again, it really doesn't show up much in terms of an Agilent P&L. But Mike and Nick, why don't you make a couple of comments in terms of the status of the transformation of the product line?
Mike McMullen - SVP & Pres of Chemical Analysis Group
Yes, thanks, Bill. I mean, we're fully engaged. We're coming to market with a number of new products over the last several quarters, so we're really starting to see the initial yield in terms of the new product introductions and the increases that will be made in the R&D, and particularly in the area of our spectroscopy business. We have a number of new offerings that have come out in the last quarter. A revolutionary introduction in elemental analysis with our MP-AES product, along with the world's smallest FTIR bench-top in the past quarter, as well.
So, the yield is there, we're getting the growth and we're going to get the share gains as we move forward into 2012. In terms of relative comment about the drag on margin, we actually look at -- on the CAG business, each quarter, the margins actually have increased, and are up over last year's level as well.
So, as Bill mentioned, we've been able to fund these increases of R&D through the operational efficiency approach that Bill mentioned, along with, we're starting to see the uptake in terms of our gross margins.
Nick Roelofs - SVP & Pres of Life Sciences Group
Yes, and on the Life Science side, as you know, the bulk of that is NMR and you're correct in pointing at it. It is a longer cycle until we see all the investments return, but we have consoles, which is about one-third of the NMR instrument fully out of Penang now. It's got design technologies from EMG in the product, and that's been shipping. So, that's been a great help in terms of both product reliability and cost. We've invested in reformatted the factory for magnets and that productivity has gone way up.
We are doing a technology roll there, but that technology roll won't be out for another year or so, but we have significant productivity in the manufacturing going up and we're putting money in the probes, which is the third subcomponent of an NMR system. We are making real progress. It's exactly what Bill said. Long cycle, it's mostly technology roll, and the money to date has been in infrastructural costs, like sales and service and some factory modifications.

Your next question is from the line of Tycho Peterson with JPMorgan. Please proceed.
Tycho Peterson - Analyst
First question, I'm wondering if you can just give us a little bit of color on what's expected in guidance from a geographic perspective. Nick had talked, I think, about Europe being up in the mid single digits for the academic business, but are you assuming in general that Europe holds steady and then also, China? You talked about 30% growth this quarter. Does that come in next year? What's embedded in the expectations?
Bill Sullivan - President & CEO
Clearly, our growth bias is to the BRIC countries that we have. Didier, do you have any additional color commentary in terms of any mix, other than -- I've been very clear that my overall growth expectations in US and Europe are low.
Didier Hirsch - SVP, CFO
I would say in general, you can assume that the growth in the countries will mirror a little bit like the growth in overall growth, where we're talking about 5% revenue growth on the 3.5% GDP growth. Obviously, GDP in China will be more like 7%, 8%. And you will have the same kind of delta between Agilent growth and the growth in those markets.
Bill Sullivan - President & CEO
Again, the reason that we feel we're just inherently going to have a higher growth rate in the world's GDP indicator would be is because of the continued mix into developing countries, where 39% of our business is in Asia and I've already given you the numbers of the progress we are making in Brazil, as well as in Russia.
Tycho Peterson - Analyst
And then in terms of capital deployment, operating cash flow was great this quarter. Any change in view on M&A? Should we still think about smaller tucked-in deals, or how should we think about the MNA environment and other capital deployment priorities?
Bill Sullivan - President & CEO
So, you again continue to model in a couple hundred million dollars a year for tuck-in acquisitions. We continue to look for larger acquisitions. And I've been very clear. The valuations continue to be quite high and we are absolutely determined to return greater than cost of capital, return on invested capital last quarter continued at 27%, and we will not make an acquisition with the shareholders' money that we don't have high confidence that we can return real value to them.
Tycho Peterson - Analyst
Okay. And then, one or two other quick ones. In oscilloscopes, you've seen strong traction there. How do we think about the cycle? How difficult is it to grow against some of the comps for that business in particular?
Bill Sullivan - President & CEO
Ron?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
For the oscilloscopes, we continue to outgrow the competition. We had revenue growth of 33% this last quarter, which I believe is stronger than any other competitor has reported, and we have record market share for ourselves, so we continue to grow that business. It's doing exceptionally well on the top line and the bottom line, and we continue to take share.
Bill Sullivan - President & CEO
I think Ron may want to speak to the digital IO investment that continues to go on in the computer industry, I think will continue to drive oscilloscope sales.
Ron Nersesian - SVP & Pres of Electronic Measurement Group
Absolutely. As we look at faster and faster bus speeds within the computer industry, they need high performance oscilloscopes to go ahead and be able to measure those signals. So, as we see all these new standards, everything from the USB 3.0 and the Thunderbolt ports and all of the other high-speed serial ports, they need our high-performance products and that drives our business.
But it's worthwhile to say that not only is our high business going well, if you look at the mainstream market, we are setting records in units that are sold with our brand-new lower-end product. So, we're taking share also in the mid-range and the low end of the portfolio. That's why I think you're seeing growth from Agilent oscilloscopes faster than the competition and why you may get back to the previous question and why some other competitors are doing some restructuring.
Tycho Peterson - Analyst
Okay, and then last one for Mike on food, he mentioned that's still largely being driven by China. Are you seeing any traction outside China for that business?
Mike McMullen - SVP & Pres of Chemical Analysis Group
I might specifically call it out for China, but I would say there's a real emerging market story for the food market we're seeing, new regulations both being passed and actually enforced in countries like India, Brazil. The food market's growing, so it's really an emerging market play. I would say it's stable in the mature markets.
We've seen a lot of rhetoric around some of the US FDA Food Safety bill, but not a lot of significant bump in business. I couldn't want you to have the impression that it's only a China story here. There's growth in many other geographies around the market.
Tycho Peterson - Analyst
Great. Thank you.

Your next question is from the line of Doug Schenkel with Cowen and Company. Please proceed.
Doug Schenkel - Analyst
Hi, good afternoon. First question, looking at your revenue guidance and how you have talked about the variable cost structure you've implemented in your target incrementals, again, just having played with my model since we got some more details, doing this real quickly, but it doesn't seem that easy to get down to $3 per share. Could you just provide a bit of commentary on what the world looks like if you were to come in at the low end of guidance?
Bill Sullivan - President & CEO
I think essentially you're going to see revenue growth that is, a couple-plus percent moving forward and somehow we aren't able to react quickly to adjust expenses moving forward. As I said, I think we've taken a balanced view going into 2012, very consistent with the model that we have shared in the past, in terms of our growth rate, between 4% and 12%.
We're essentially giving guidance in that lower part, given the economic uncertainty, but we are taking a very conservative position going into next year. We're going to continue to drive our gross margins, and you would have to have some sort of very low growth and a bad mix, I think, to effectively end up at the very low end range.
Doug Schenkel - Analyst
Okay. That is helpful. Turning to EMG, the backlog, the order book was robust in dollar terms. That said, book-to-bill ticked down a little bit again. Anything you want to point out to make sure folks don't get concerned and it doesn't become you're concerned about that dynamic?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
No, we shipped $33 million, or recognized $33 million more in revenue than orders and we have built up $200 million worth of backlog in the last fiscal year. So, our plans are to reduce our backlog more over the coming next two years.
So, we need to get ahead of that. We put capital investment in place, and we're very pleased to be able to go ahead and reduce our backlog. And of course, the incrementals that we're producing, as we view that, are putting real results on the bottom line.
Doug Schenkel - Analyst
Okay, and last one on the Life Sciences Group side, the revenue adjusting for FX was dead-on with your expectation. That said, America's growth was pretty weak, although it was a tough comp. I would be curious if you could talk about pacing, provide any color on what the impact of funding uncertainty was in the US. Then again, looking at the book-to-bill, that was pretty good. Does that suggest things may have picked up in the quarter in any geography?
Nick Roelofs - SVP & Pres of Life Sciences Group
Yes, I'll dive into some of that and if Didier wants to add anything or Bill does. First of all, Americas, you did see the softness I mentioned earlier, which was really heavily academic government, and that's what we saw in the quarter. Some orders came in late, so I think you did hit the nail on the head. Good book-to-bill and late orders show that we did have some pickup at the end of the quarter. That pickup was not in the Americas.
The continuing resolution funding that's funding academic government is freezing that up, and there's some question about whether the pharma guys are going to get impacted, depending on the special committee, and what that does to Medicare. So, Americas are still trickling along. Again, to Bill's comment, our expectations on the Americas are above, but in line with GDP there. So, America's GDP going forward is not going to be a big number. We'll do better than that number, but it's not a big number for us, in terms of growth.
Doug Schenkel - Analyst
Okay. Thanks for taking all the questions.

Your next question's from the line of Richard Eastman with Robert W. Baird. Please proceed.
Richard Eastman - Analyst
Yes, just three questions, two for Ron. Ron, given that you're talking about, and we kind of rolled this up to about 4% growth including backlog shipments. Is that enough volume growth to drive margins higher, or do we see a decremental on that kind of volume growth?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
No, we're committed to deliver roughly the 40% incremental on our incremental revenue.
Richard Eastman - Analyst
Okay, all right. And then also, on the same volume question, is pricing holding up buying? Is that in the volume growth, a good enough outlook against a given backlog? Is the core volume forecast, growth forecast for EMG in fiscal 2012 enough to kind of protect the price?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
Yes. There's a very wide range in price, depending on the products, depending on the market that we sell into. So, for instance, in oscilloscope, we sell some for $1,000 and other ones that go completely loaded for $300,000.
So, there's a lot of dynamic range, which is effective in the mix. When you see a quarter that you have a lot more wireless manufacturing growth than you see in R&D, the margins will typically go down a little and vice versa when R&D is higher.
Richard Eastman - Analyst
Sure.
Ron Nersesian - SVP & Pres of Electronic Measurement Group
So, we feel very comfortable with that. We did, we did have the highest gross margin ever for fiscal year 2012, compared to any other year, since we've been Agilent. And again, our pricing in general is fine, but there are mix issues that move things around within a point as we move, move forward.
Richard Eastman - Analyst
And just the last question, just on the geographic numbers, Didier, that I think you mentioned, orders were down 6% in Japan, yet revenue up, I think those were LC numbers, local currency numbers. But I was curious, in Japan, which of the business groups is that impacting? Is that LS?
Didier Hirsch - SVP, CFO
So, in Japan, 6%. It was very, very comparable, EMG and bioanalytical, about 5%, 6% for both of them, in terms of order growth core, excluding currency. So, it was about the same thing.
Richard Eastman - Analyst
Both -- okay.
Didier Hirsch - SVP, CFO
For orders.
Richard Eastman - Analyst
Yes. Okay, thank you.

(Operator Instructions). And your next question is from the line of Ajit Pai with Stifel Nicolaus. Please proceed.
Ajit Pai - Analyst
Good afternoon, and congratulations on record operating margin.
Didier Hirsch - SVP, CFO
Thank you.
Ajit Pai - Analyst
Two questions. The first one is looking at the Electronic Measurement segment and your seasonal pattern, going from July to October, only twice I think in your history, once in 2001 and then again in 2008 where your revenues for the October quarter after July have been down. Could you give us some color from a revenue perspective, on a sequential basis, what exactly is happening there.
Then, given your strong commentary on communications tests, going into next year, what do you expect from the handset test market, with all the capacities in place for the handset demand growth that we see, or whether that's a business you could still expect some robust growth?
Bill Sullivan - President & CEO
Go ahead, Ron.
Ron Nersesian - SVP & Pres of Electronic Measurement Group
We think the handset market will continue to grow. It will grow as we see smartphones roll out into the 3G marketplaces. We even see some people upgrading from general 2G to 3G, as well as people putting in new lines for 3G, in addition to obviously folks that are going on 4G. So, basically you see all of the different technology waves contributing a certain portion to our growth.
As far as our revenue growth, it's not surprising at all. We've had some numbers where we've grown over 20% in the past, and now you can see the growth rate, the revenue growth rate has come down to about 12%, which we think is pretty decent.
Ajit Pai - Analyst
Right, and on the sequential growth, between July and October, the pattern you're seeing in this particular year, related to prior years, whether that's going to be -- what is responsible for that and going forward, do we expect years that are more similar to 2011, or years that have a seasonal pattern that's more similar to a regular pattern of having a nice sequential uptick of revenue in October?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
Well, we have small customers and we have big customers. And depending on what's going on, it can go ahead and it can move the quarter-to-quarter sequential growth rates between them. But we typically will see in the future, Q4 being higher. But we had such an outstanding Q3, we did not have as an outstanding Q4. But still, well -- a very strong quarter overall.
Ajit Pai - Analyst
But, no significant areas where you saw weakening during the quarter?
Ron Nersesian - SVP & Pres of Electronic Measurement Group
No significant orders. Overall, the orders are softer than the growth rates we've seen in the past, when we built off a much, much lower revenue number. But, as you can see, our order rate overall was roughly flat.
Ajit Pai - Analyst
Got it. And then the second question is just looking at competitive response, you talked about some restructuring with competitors, et cetera, but from a pricing and product introduction perspective, in the past two years with all the focus that they have had in electronic measurement, and also on LS, CA side, especially with Varian and refreshing the product portfolio, is there any notable competitive response in terms of either changing in the pricing environment, or in terms accelerating new product development that is notable?
Bill Sullivan - President & CEO
No, we see competitors moving into the marketplace, we'll see Rohde & Schwarz add some products and some other people try to combine some things, but that's really not driving or changing our results. A matter of fact, in the oscilloscope market where you see it, we're outgrowing everybody.
Ajit Pai - Analyst
Right, and any changes in the LS CA on the Life Sciences and Chemical Analysis side, post-Varian integration and having the entire new product roll out and your new directive versus the Life Science side that you'd been investing in?
Mike McMullen - SVP & Pres of Chemical Analysis Group
Ajit, this is Mike. I'll make a few comments and perhaps Nick wants to build on this, but very similar response you heard from Ron, the pricing structure has remained really quite stable. We have pockets here and there of competitors trying to win certain accounts, but nothing out of the norm.
And in fact, as we've improved the strength of the portfolio, making it even more competitive, we're even in a stronger pricing position, so I think pricing has not been an area of concern for us.
Nick Roelofs - SVP & Pres of Life Sciences Group
And I'll just echo that, Ajit. In the LS market, you hit the nail on the head. Focus channel, lot of new products, there's a lot of pressure out there, particularly in the academic government sector. But we have not seen any erosion in our product pricing based on that.
Ajit Pai - Analyst
Got it. Okay. Thank you so much.

Your next question's from the line of Derik De Bruin with Bank of America. Please proceed.
Derik De Bruin - Analyst
So, most my questions have been answered, so just going to ask a couple of nit-picky ones. So, on the -- you made a comment saying that you potentially thought you could see some softness in the pharma spending environment, as people are worried about the Medicare impacts. Yet you were talking about the replacement cycle in the pharma is -- pharma and biotech still looks pretty good.
Is that a geographical split we're talking about here, the difference between the two comments? Are you talking about North American pharma being a little bit soft in the R&D, yet your international and your European replacement business is looking better?
Nick Roelofs - SVP & Pres of Life Sciences Group
Yes, Derik, thanks for the clarifying question. And exactly correct. The comment on softness was Americas pharma and overall comment was global, which means good strength in Europe and good strength in emerging countries where big pharma is moving.
Derik De Bruin - Analyst
Okay, and I'm curious, as you've rolled out the 1290, has your attachment rate on the columns improved as you've seen it, or are people still swapping and using their, using other columns on it? I'm curious if that dynamic has started to come in with the UHPLC business.
Nick Roelofs - SVP & Pres of Life Sciences Group
Yes, the attachment rate is much improved compared to the past, and I think it's down to the number of people that provide a UHPLC column, is very, very small. So now, what we're seeing is, people are buying their columns with their box and I think others have made that comment, too. And we expect that to be a cycle that holds for a while, while the column technology in ultra high pressure is way ahead for us and others who make instruments, as opposed to general column makers.
Derik De Bruin - Analyst
Great, and one other final one. Obviously there's some issues in terms of overcapacity right now in the sequencing market, and I think there's also some uncertainty about what the array market looks like. Can you kind of talk about what you're seeing, obviously your target selection is a little bit different than where your competitors are, but just talk about what's the impact of the genomics markets?
Nick Roelofs - SVP & Pres of Life Sciences Group
Sure. First on the sequencing market, there may be overcapacity in boxes, but those boxes are getting used. And what we sell are reagents to the utilization of the box. So, we will naturally have a trailing edge curve that's at least is it 12 months out if it flattens, and our number growth this quarter in sequencing, partitioning is consistent with the growth rate of the major player four quarters ago. So, it's still very robust in utilization. In regard to -- so what was the other question?
Derik De Bruin - Analyst
Arrays.
Nick Roelofs - SVP & Pres of Life Sciences Group
Sorry, thank you, arrays. In regard to arrays, that market is very soft. We're doing fine in the specific cytogenetic CGH utilization, but that market is rapidly being cannibalized by sequencing for gene expression. That's not new to Agilent, so we're not surprised by that, and we've always been weak there.
Derik De Bruin - Analyst
Great, thank you.

Your next question's from the line of Isaac Ro with Goldman Sachs. Please proceed.
Unidentified Participant - Analyst
Hey, guys. Thanks for taking the question. This is actually Justin for Isaac. Just on the comments on the academic government weakness in the quarter, can you talk about how that paced throughout the quarter and if there was any split on instruments versus consumables or any other product area where you saw the weakness?
Bill Sullivan - President & CEO
Yes, I won't split it by products because it's fairly complex. But the pacing through the quarter, we commented last call about the fact that the end of July was a big trough and that August seemed to pick up. What has happened during the quarter is, through August and September things were pretty decent.
That was spending out the year-end money of fiscal year 2010. The RO-1 grant money is not flowing because everybody is in continuing resolution mode. And so, the October numbers have been very soft.
Unidentified Participant - Analyst
Thanks a lot. And then looking at the margins on both LSG and CAG, we saw nice improvement this quarter, and a lot of that is since you guys worked throughout the integration. Can you talk about the pacing and improvements in margins going forward through next year and if there's any specific events we should be watching for in the first half of the year?
Bill Sullivan - President & CEO
First of all, I just would suggest you look at very, very steady progress over the year, built into our plan. I think a realistic number, I hope that Mike and Nick are able to beat that number, but you should see continued improvement as we go through fiscal year 2012.
Unidentified Participant - Analyst

And your final question is a follow-up from the line of William Stein with Credit Suisse. Please proceed.
William Stein - Analyst
Great, thanks. There's been a lot of discussion about the floods in Thailand impacting the supply chain in the electronics market generally. I'm wondering if you can talk about whether there's been any impact on Agilent's business and whether there may be any opportunity to sell into the optical test market.
Ron Nersesian - SVP & Pres of Electronic Measurement Group
There's been no impact to our overall supply chain due to that event. There may be some folks that are retooling, which may present some type of business upside for us. But, we've had no supply chain impact.
