Welcome to the second quarter of 2021 Caterpillar earnings conference call. Please be advised that today's conference is being recorded. I would now like to hand the conference over to your speaker today, Jennifer Driscoll. Thank you. Please go ahead.
Thank you, Whitney. Good morning, everyone. Welcome to Caterpillar's second quarter 2021 earnings call. With me here today are Jim Umpleby, Chairman of the Board and CEO, Andrew Bonfield, Chief Financial Officer, Kyle Epley, Vice President of the Global Finance Services Division, and Rob Rengel, Senior IR Manager. During our call this morning, we'll be discussing the earnings news release we issued earlier today. You may find our slides in the news release and a video recap at investors.caterpillar.com. Simply click on Events and Presentation. Moving to slide two, the forward-looking statements we make today are subject to risks and uncertainties. We'll also make assumptions that could cause our actual results to be different than the information we're sharing with you on this call.
Please refer to the recent SEC filings and the forward-looking statements reminder in the news release for details on factors that individually or in aggregate could cause our actual results to vary materially from our forecast. Caterpillar has copyrighted this call, and we prohibit use of any portion of it without our prior written approval. Today, we reported profit per share of $2.56 for the second quarter of 2021, compared with $0.84 of profit per share in the second quarter of 2020. We're showing adjusted profit per share in addition to our U.S. GAAP results. Our adjusted profit per share was $2.60 for the second quarter, compared with second quarter 2020 adjusted profit per share of $1.27. Adjusted profit per share for both quarters excluded restructuring costs. The second quarter of 2020 also excluded a remeasurement loss of $0.19 per share resulting from the settlement of pension obligations.
We provide a non-GAAP reconciliation in the appendix to this morning's news release. You also can find information on dealer inventory and backlog in our slides. Let's flip to slide three as we turn the call over to our Chairman and CEO, Jim Umpleby.
Thanks, Jennifer. Good morning, everyone. As we close out the first half of 2021, I'd like to thank our global team for their strong performance in a challenging dynamic environment. We continue to execute our strategy for profitable growth and remain focused on the safety of our employees. We're encouraged by higher end user demand in the majority of our end markets. Before turning over the call to Andrew for a detailed review of our results, I'll briefly cover three topics this morning. I'll share my perspectives on Caterpillar's second quarter results. I'll review our end markets before discussing the sustainability report, including our new climate and energy statement that we published during the second quarter. On slide four, we're pleased with the strong sales and profit performance during the second quarter. Sales and revenues increased 29%, primarily due to higher sales volume.
The two main drivers of our top line were strong end user demand and the impact of changes in dealer inventory. Compared to the second quarter of last year, sales to users rose roughly 15%, and changes in dealer inventories provided about a $1 billion tailwind. During our first quarter call, we mentioned that growth in sales to users would be significantly higher than the 8% we saw in the first quarter. Sales to users rose about 15% versus the second quarter of last year and trended better for the fourth consecutive quarter. We had gains in all three of our primary segments. Machines rose 20% with similar increases in both Construction Industries and Resource Industries with improvement in all regions. Demand from residential construction remained strong, and demand related to non-residential improved. Mining was also up.
Quotation activity for miners remained strong. We've seen a significant improvement in orders through the first two quarters. We were also pleased that heavy construction and quarry and aggregate strengthened, as did several end markets within Energy & Transportation. Energy & Transportation sales to users turned positive, rising 1%. Keep in mind that the slowdown in end user demand in 2020 affected Energy & Transportation later than the other segments, as some of the applications are impacted by timing of large products. From a geographic perspective, we had strength in sales across all regions. North America was quite strong, as expected. EAME and Latin America also showed double-digit sales growth. Asia Pacific saw good growth in most areas outside of China. China declined modestly in the quarter after rebounding strongly beginning in the second quarter of 2020, leading to a tougher comparison.
We also had modest benefits to sales this quarter from currency and price. As we noted in our first quarter call, second quarter 2020 saw a decline in dealer inventory of $1.4 billion, but we did not expect a significant change during 2021. Dealer inventory declined $400 million during the second quarter. Similar to the first quarter of this year, dealer inventory remains near the low end of the normal range. I'll now provide an update on Caterpillar supply chain. In spite of the unprecedented challenges impacting the industrial sector, I'm proud of the work by our team to minimize disruptions, which were relatively modest during the second quarter. For the majority of our products, availability remains within our normal ranges.
We mentioned on the last earnings call that the supply chain situation, including transportation, was challenging and that our team was preparing contingency plans such as alternative assembly processes at our facilities. During the quarter, our team implemented some of those plans and continued to work closely with our suppliers to mitigate supply chain impacts on production. We still anticipate that supply chain challenges will remain throughout the year, and our goal is to minimize the impact on our ability to meet improving customer demand. In addition, as we mentioned during our last earnings call, we do not expect a significant benefit from dealer restocking during 2021. Operating profit in the second quarter increased 128% to $1.8 billion. Volume growth, price realization, and strong results from Financial Products drove the improvement. We did have some favorable price flow through this quarter, mostly in Construction Industries.
We also saw higher short-term incentive compensation expense and some higher material costs, including steel and other commodities as expected. Andrew will discuss margins in more detail. The adjusted operating profit margin improved to 14.1% versus 9.3% in the second quarter of 2020, as we expected. Operating margins increased in both Construction Industries and Resource Industries, despite headwinds from short-term incentive compensation and supply chain challenges. Profit per share was $2.56 versus $0.84 in the second quarter of 2020. Adjusted profit per share was $2.60 versus $1.27 in the second quarter of 2020. Moving to slide five. Free cash flow from Machinery, Energy, and Transportation was another highlight of the quarter. We generated $1.7 billion of ME&T free cash flow with higher profit partly offset by an increase in Caterpillar inventory. We resumed share repurchases in the second quarter.
We also announced we're increasing our quarterly dividend by 8% to $1.11 per share. We paid a higher dividend annually for 27 consecutive years. We returned about $800 million to shareholders in the second quarter via the dividend and share repurchases. We expect to repurchase sufficient shares between now and the end of the year to at least offset absolute dilution from shares issued this year. In light of the highly fluid environment, we will continue our practice of not providing profit per share guidance. However, we'll share some high-level assumptions for the upcoming quarter and the full year.
For 2021, as we said on the last earnings call, we expect to achieve the targets for adjusted operating profit margin that we set out at our 2019 Investor Day of 300-600 basis points of improvement versus our performance during the 2010-2016 period at similar sales, similar levels of sales and revenues. We also expect to achieve the free cash flow targets we set for ME&T at Investor Day of an incremental $1 billion-$2 billion at all points in the cycle. Andrew will elaborate with a few of our assumptions for the upcoming quarter in a few moments. Please turn to slide six, I'll walk through our expectations by end market. Overall, we're becoming more optimistic about our end markets since our last earnings call. We're pleased that many end markets continue to improve and demand continues to strengthen.
Global demand is strong and the outlook is positive. In Construction Industries, for example, we're optimistic about the industry as we expect end market demand to show continued positive growth. Residential and non-residential construction demand is expected to remain strong, led by North America. In China, we expect the industry for excavators above 10 tons to be about flat in 2021 compared to a very strong 2020. Please keep in mind that demand was very strong in this market during the first quarter. Our newly introduced GX models continue to perform well, and we're still receiving positive customer feedback. In the balance of Asia Pacific, we believe stronger than expected commodity prices, housing strength, and government infrastructure expenditures will support continued sales growth. In EAME, we see end market demand regaining momentum on strong construction activity, higher commodity prices, and improved confidence.
Latin America should also show continued strengthening due to increased construction activity. Switching to Resource Industries. In mining, we continue to expect improvement in miner CapEx as commodity prices remain supportive of growth. Parked large mining trucks decreased in the quarter and remain at relatively low levels in all regions as utilization increases. Customer interest in Caterpillar's autonomous mining solution remains high, and customers now autonomously operate or are deploying Cat machines on 18 sites around the world. While our mining customers continue to display capital discipline, we expect mining to continue to improve over the long term as the energy transition drives higher demand for commodities. In heavy construction and quarry & aggregates, we've seen improvement in the second quarter, particularly in North America and EAME. We expect continued strengthening in this part of the portfolio.
Finally, in Energy & Transportation, we expect oil and gas to continue to strengthen gradually. We expect customers to continue to demonstrate capital discipline and pockets of excess capacity remain. In power generation, strength in data centers should continue. Industrial demand is expected to improve along with the global economic recovery. Transportation should see strength in rail services and growth in international deliveries for locomotives, and marine demand is projected to grow modestly while remaining at low levels. Now on slide seven. Since our last quarterly earnings call, we published our 2020 sustainability report to establish and report progress against our environmental, social, and governance goals. We also released a new climate and energy statement. Caterpillar shares the concerns of governments and the public about the risks of climate change and supports global efforts to mitigate its impact. We are committed to contributing to a reduced carbon future.
This commitment is reflected in our sustainability vision to improve the quality of the environment and our communities. Some of the way we do this are by further reducing greenhouse gas emissions from our operations and helping customers meet their climate-related objectives by investing in innovative new products, technologies, and services. Our 2020 sustainability report highlights seven new environmental, social, and governance goals we've set to achieve by 2030. These goals, which address issues most relevant to our customers and other stakeholders, are focused on the climate and environment in addition to safety. One of these goals is to ensure that 100% of Caterpillar's new products through 2030 will be more sustainable than the previous generation. It's an inspiring time to be a Caterpillar employee. I'm pleased with all the good work already underway across the company.
We're developing products and services that facilitate fuel transition, increased operational efficiency, and reduced emissions to help communities thrive and to help our customers achieve their environmental goals. By establishing and reporting progress on our ESG targets, we provide transparency about our progress and innovation. In order to further increase transparency, we will strive to provide an update or example during our earnings calls. This quarter, I'll close with an example. Recently, Nouveau Monde Graphite, or NMG, announced a collaboration with us to fully power their Matawinie graphite mine with zero-emissions machines by 2028. Caterpillar will be the exclusive equipment, technology, and service provider for NMG. We'll be developing, testing, and producing Cat zero emission machines for the project in Saint-Michel-des-Saints in Quebec, Canada. In conclusion, we continue to execute our strategy for long-term profitable growth by investing in services, expanding our offerings, and improving operational excellence.
It was a strong quarter from a financial and operational perspective, and a good first half. Looking forward, we're optimistic about our ability to mitigate supply chain challenges and are encouraged by customer demand that's strengthening and is broad-based across all regions. Now, I'll turn the call over to Andrew.
Thank you, Jim. Good morning, everyone. I'll start by walking you through second quarter results, including some color on the segment performance. I'll turn to the balance sheet and our thoughts for the third quarter. Beginning on slide eight, as Jim noted, sales for the second quarter increased by 29% to $12.9 billion due to higher volumes. Operating profit of $1.8 billion increased by 128%, reflecting margin expansion, primarily due to higher volumes. Second quarter profit per share was $2.56 compared with $0.84 in 2020. Adjusted profit per share more than doubled to $2.60 compared with $1.27 last year. I'll start with the top line on slide nine, where we continue to see strong volume gains. Sales and revenue growth was in the double digits % for all three of our primary segments, and on a consolidated basis for every region.
Growth in North America, our largest region, was up 30%, reflecting strong results in Construction Industries and Resource Industries. Growth in EAME was also robust, up 33%. Latin America rose by 67%, albeit off a slow base. Asia-Pacific sales grew by 12%. Overall, sales to users increased by 15%. The acceleration from the 8% rate of growth in the first quarter was in line with our expectations of a significantly higher percentage, as we discussed last quarter. Sales to users in Construction Industries rose by 20%, led by North America. Residential construction continued to be strong in North America and EAME. Non-residential construction in North America is recovering well as well. Latin America showed very good growth in sales to users off a low base. Asia-Pacific was lower due to a modest decline in China.
As Jim mentioned, the Chinese market started to recover earlier in 2020 than other countries, leading to a tougher comparative. Overall, we still expect China to have another strong year with the industry in the above 10-ton excavator market about flat, retaining last year's large gain. Sales to users in Resource Industries increased by 21%, reflecting growth from heavy construction and quarry and aggregates. Demand for equipment and mining also improved this quarter, and as Jim mentioned, we remain encouraged about the upside potential in mining. In Energy & Transportation, sales to users rose by 1% in positive territory, despite the fact that E&T sales to users were impacted to a lesser extent than other segments in the second quarter of last year due to the timing of large deals. Now turning to slide 10. Operating profit increased to $1.8 billion.
The 128% improvement reflected higher volume in our three primary segments, favorable price, and higher profits from Financial Products. That was partly offset by the impact of restoring short-term incentive compensation. The assumption for short-term incentive compensation in the quarter was also raised by about $100 million compared to the first quarter to reflect our strengthening results. We now expect our full-year charge to be about $1.5 billion. This quarter, we had $25 million in restructuring expense, over $100 million lower than a year ago. We now expect around $250 million in restructuring expenses this year. We also had a full quarter impact of SPM Oil & Gas, including some M&A related costs, which I'll cover in a bit more detail when we discuss Energy & Transportation. The adjusted operating profit margin rose 480 basis points to 14.1%. As we expected, research and development and selling general and administrative expenses rose.
These increases reflected not only the impact of incentive compensation, but also investments in key priorities such as growing services and investing in product development to help our customers achieve their climate objectives. As we explained in April, we did expect a sequential decline in margins versus the first quarter. Margins were broadly in line with our expectations. As we said, price realization turned positive in the quarter, while material and freight costs were a negative. We did see a lower margin reduction than expected from absorption as production rates remained strong. However, the increase in short-term incentive compensation more than offset that. The global tax rate remains about 26%. Adjusted profit per share of $2.60 excludes $0.04 of restructuring expense versus $0.24 of restructuring expense, as well as $0.19 for the settlement of pension obligations that occurred in the second quarter of last year. Moving to slide 11.
Let's take a look at segment performance, starting with Construction Industries. Sales increased by 40% to $5.7 billion, primarily driven by higher sales volume and favorable price realization. The improvement in volume was due to higher end user demand and the impact from changes in dealer inventories. As I mentioned earlier, the increase in end user demand was led by North America, where residential construction remained strong and non-residential construction strengthened. Overall, dealers reduced their construction equipment inventories less in the second quarter of 2021 than in the second quarter of 2020. The segment's second quarter profit increased by 98% to $1 billion. The near doubling came from higher sales volume and favorable price realization, including geographic mix. Cost absorption and efficiencies were positive in the quarter.
That was partly offset by two items, the impact of short-term incentive compensation, and we started to see the impact of unfavorable material costs, although this was modest in the quarter. The segment operating margin increased by 530 basis points to 18.1%. Turning to slide 12. Resource Industries sales increased by 41% in the second quarter to $2.6 billion. The increase was mostly due to higher end user demand for equipment and aftermarket parts and changes in dealer inventories. As we expected, heavy construction and quarry and aggregates began to improve, we expect continued improvement from here. End user demand in mining also continued to improve. Sales were up in all regions. Second quarter profit for Resource Industries more than doubled, increasing by 138% to $361 million. The increase was mainly due to higher sales volume, partially offset by the impact of our short-term incentive compensation expense.
Price was slightly negative, mostly due to changes in prices for Australian dollar-denominated aftermarket parts. These were reduced to reflect currency movements versus the U.S. dollar. The operating margin increased by 570 basis points to 14%. Now on slide 13. Energy & Transportation sales increased by 20% to $5 billion. That included an 11% sales increase in oil and gas, largely due to higher sales of reciprocating engine aftermarket parts, driven in part by the addition of SPM Oil & Gas. Power generation sales improved by 18%, reflecting increased sales for large reciprocating engine applications, primarily for data centers. Industrial sales increased by 33% with demand across all regions. Transportation rose by 10% on higher rail services and marine sales. Profit for E&T increased by 17% to $731 million. The improvement was due to higher sales volume.
That was partially offset by a couple of factors, including the impact of short-term incentive compensation and acquisition-related expenses, primarily for SPM Oil & Gas. Higher freight costs were offset by manufacturing efficiencies. The segment's operating margin declined by 30 basis points to 14.7%. With regards to SPM Oil & Gas, we do expect this to be a modest drag on margins for E&T for the remainder of the year. This was the first full quarter since the acquisition, and it will take some time for the synergies to be realized. We're very pleased with the acquisition and expect to see the full benefits of the acquisition as we move forward. On slide 14, Financial Products revenue increased by 1% to $774 million as the portfolio remained relatively constant. Segment profit remained strong, increasing by 64% year-over-year to $243 million, which was about flat compared to the first quarter of 2021.
The year-over-year profit increase was due to a lower provision for credit losses at Cat Financial compared to the year ago quarter, which reflected the absence of forecast of COVID-19 related impacts. In addition, we had a higher net yield on average earning assets due to a favorable change in weighted average interest rates, and a favorable impact from returned or repossessed equipment benefiting from higher demand for used equipment. Our credit portfolio remains in good shape as indicators of customer health are all positive. Past dues continue to improve to 2.58%, down 116 basis points year-on-year, and down 32 basis points compared to the first quarter. Credit applications remain strong as well, up 5% compared to the second quarter of 2020 and up 9% compared to the first quarter.
New business volume continues to trend up, led by North America, with requests for loan modifications have returned to historical trends. Moving to slide 15, we're confident that in 2021, we'll achieve our Investor Day target for ME&T free cash flow of $4 billion-$8 billion. ME&T free cash flow was $1.7 billion in the second quarter compared to $500 million last year. The increase in ME&T free cash flow reflected higher profit, offset in part by a $500 million sequential increase in Caterpillar inventory in the second quarter of 2021. The inventory increase is primarily in components and work-in-process inventory and reflects strengthening end user demand and our response to supply chain challenges. ME&T free cash flow has been $3.4 billion year-to-date, benefiting from higher profits as well as the absence of paying short-term incentive compensation in the first quarter.
We continue to maintain a solid liquidity position in support of our strong mid-A credit rating. The company ended the period with $10.8 billion of enterprise cash. We've said that we intend to return substantially all of our ME&T free cash flow to shareholders through the cycles. We've said that we will do it through a combination of dividends and share repurchases, reserving our balance sheet to fund additional growth initiatives and mergers and acquisitions. In the past three years, we've returned on average 106% of our ME&T free cash flow to shareholders. This quarter, we announced we'll increase our quarterly dividend by 8% to $1.11 per share, which is about $600 million per quarter. I'm happy to say we expect to extend our status as a Dividend Aristocrat for another year. We repurchased about $250 million of our common shares this quarter.
We have about $4.6 billion remaining under the current share repurchase authorization. We expect to continue to repurchase shares in the second half and intend to at least offset absolute dilution from shares issued during the year. As Jim mentioned, there's no change to our current practice relating to guidance. However, as we've been doing, we are providing color on the upcoming quarter to give you a sense of what we're expecting to happen. Moving to slide 16. Again, we expect to achieve our Investor Day targets for adjusted operating profit margins in 2021, despite reinstating the short-term incentive compensation program. That's now projected to be a headwind of $1.5 billion for the year or about 300 basis points of pressure on margins. We expect stronger sales than normal seasonality would imply.
The growth rate in sales to users should continue to accelerate in the third quarter when compared to the prior year and should be significantly higher than the 15% rate we saw in the current quarter. In Construction Industries, we expect improvement in residential and non-residential construction demand to continue. As we discussed last quarter, we see tougher comparisons in China. Resource Industries end user demand should see support from both mining and heavy construction and quarry and aggregates. We also expect Energy & Transportation sales to increase on stronger underlying demand. All of this is expected to lead to good volume growth in the third quarter, even while we manage supply chain challenges. As we told you last quarter, and as Jim mentioned today, whilst dealers are independent businesses and make their own decisions about their inventory, we don't expect a significant benefit from restocking in 2021.
Third quarter margins are expected to be stronger than the prior year, with leverage from strong volume more than offsetting the impact of reinstating short-term incentive compensation. However, we anticipate third quarter margins to moderate versus the second quarter as we see some cost headwinds in the second half of the year. Within machines, we currently expect price to offset higher manufacturing costs in 2021. In the second quarter, price was strongly positive, reflecting strong geographic mix benefits and higher price realization.
We did put through price increases for machines at the end of the second quarter, which will be positive, but geographic mix will be less of a benefit. Although we did take pricing actions, we do expect higher manufacturing costs, which means that our gross margin percentage will be moderately lower in the second half of the year versus the first half. We should also see accelerated spend in SG&A and R&D in the back half of the year as business gets back to normal.
Specifically within Energy & Transportation, we expect some margin headwinds in the second half of the year. As E&T is a lumpy business with varying margin structures across its applications, we expect variability in both price and mix, particularly as larger deals are recognized into revenue. In addition, as many of the E&T applications are experiencing different levels of demand, we did not put through additional price increases in the second quarter. This means material and freight cost increases will be a headwind for that segment. In summary, on slide 17, demand continued to strengthen in the quarter, leading to strong volume growth. Adjusted operating profit margins improved by 480 basis points, driven by higher volumes, which more than offset the nearly 300 basis headwind of short-term incentive compensation and the smaller headwinds of supply chain disruption and material cost inflation.
Adjusted profit per share more than doubled in the quarter. We are confident in the outlook for our end markets and expect to achieve our Investor Day margin and free cash flow targets. With that, we'll take your questions.
Your first question comes from the line of Jamie Cook from Credit Suisse. As a reminder, management asked that we limit to one question per analyst. Your line will be muted after you ask your question. However, if your question is not answered for any reason or clarification is needed, please get back onto the queue. Jamie, your line is open.
Hi, good morning.
Morning, Jamie.
My first question, Jim, if you could just provide some more color on what you're seeing on the supply chain side and when you expect some of the supply chain issues to ease, and I guess to what degree is your 2021 top line limited by supply chain or the inability to get product out the door? Thank you.
Thanks, Jamie. Firstly, we greatly appreciate the efforts of our employees to manage the challenges in the supply chain. One of the things that we're seeing, of course, is improving end user demand is adding pressure in the supply chain and on freight as well. Some of the supply chain challenges are more broad-based than occurs in a normal upturn. You may think about the last upturn, we had casting issues and some other individual component issues. This time it's more broad-based than is typical. Having said that, again, as we said in the last call, our team is working very hard to avoid or minimize those supply chain challenges that would impact our ability to fully meet improving customer demand. We think that the impact to the second quarter was modest. Again, we're working very hard to try to limit them.
We haven't had some of the large factory shutdowns for weeks that you've read about with some other industrial companies. We've also taken some actions to do things like with resins, we changed our material spec due to shortages that were out there, and it helped us keep production going. Majority of our products for end users are delivered within their normal ranges of availability. Some of the bigger challenges have been on the smaller products, BCP. A lot of those products are used in residential in North America. Those are some of the bigger challenges we're having in terms of availability. The majority of our products for our end users are within the normal ranges. We're working very closely with our dealers to try to ensure that we meet actual customer demand.
Your next question is from the line of Jerry Revich with Goldman Sachs.
Yes, hi, good morning.
Morning, Jerry.
Morning, Jerry.
Jim, I'm wondering if we can just dig into the environmental goal targets that you just updated us on. In terms of when we look at just quantifying the mix of orders today, that's either your autonomous solutions in mining or zero emissions products across the portfolio. Can you just help us quantify where we stand now in terms of actually driving orders for those types of products for you folks today that also improve and hit the environmental goals for your customers? Thanks.
Thank you, Jerry. You mentioned autonomy and the demand for autonomous products continues to be quite strong. A lot of quotation activity going on. As I mentioned earlier, we currently are deploying autonomous mining equipment in 18 different sites, 10 customers, three continents for a whole variety of commodities, iron ore, copper, oil sands, gold, coal mines. Again, we believe that will continue to grow at a rapid pace. We're also expanding our autonomous solutions to other support equipment like dozers, drills, underground equipment, and water trucks as well. In terms of zero emissions products, we're very focused and working closely with our customers to meet their needs. We talked about the NMG announcement during the call here already this morning.
That's a great example of one where a customer has a need, they have a date they have to meet, we're working very closely with them as their exclusive supplier with product and technologies to make it happen. Again, we're working very closely to develop products to meet customer demand. As you can imagine, it's a big topic of discussion and focus by our leadership team and something we'll continue to do moving forward. Some of the goals we put out in our sustainability report, we talked about 100% of our new products through 2030 will be more sustainable than the previous generation in some manner. We're very focused on doing that. Again, if you look at our climate and energy statement, it talks more about some of our approaches and our specific goals for reducing greenhouse gas emissions in our own operations.
Again, our strategy here, we'll work on greenhouse gas emissions and be more sustainable in our own operations and are very focused on helping our customers meet their goals as well.
Your next question is from the line of Rob Wertheimer with Melius Research.
Hi, thank you. Good morning, everybody.
Good morning, Rob. How are you?
I actually had a question on autonomy as well. The expansion to 18 sites is momentum for sure. You've talked in the past about examples of where sites have saved 20% or 30%, I think 30% productivity. Not just a driver, but mining more, with less cost, less time, less waste, et cetera. I wonder if you have any update on just as you've expanded, is that consistent? You're seeing that, you mentioned a bunch of different sites you're at, different minerals. Is that consistent across sites? Is there a potential at least for Cat to share in some of those savings? Are you selling hardware at this point, or do you have developing revenue models with customers where you can promise greater productivity and share in some of the benefits? Thank you.
Thank you, Rob. That 30% productivity increase is actually something that was stated by a customer, not us. In our view, our customers are in fact seeing productivity gains, which is one of the reasons that adoption continues to move forward. I believe it's also really accelerating. It's clear that our customers are seeing the benefit, or they wouldn't be continuing to put an autonomous operation. There's a variety of models that we have that we use with our customers. Typically, there's a monthly kind of fee that we receive. Of course, we sell the equipment to them as well. Again, commercial models are very dependent upon individual customer negotiations.
Your next question is from the line of David Raso with Evercore ISI.
Hi, good morning.
Good morning, David.
Just a straightforward kind of near-term question. The supply chain issues, when we think of your normal, at least historical, normal sequential revenue, 2Q, 3Q, 4Q, given the supply constraints, but balance, of course, demand strong, how should we expect the revenue cadence to be versus the historical norm of third quarter's down about 5%, and then the fourth quarter's back about 10%? Thank you.
Yeah. Thanks, David, hi. Yes, obviously, what we are seeing though is this is an atypical year. As we've indicated, we don't necessarily expect a normal seasonal pattern, between Q2 and Q3. Obviously, underlying volumes, we do believe, and particularly in end user steel, we do expect to grow significantly and that rate of growth to be higher than the 15% we saw in Q2. That will mean that probably we don't expect that normal pattern, and that's a factor which we have to look at. Obviously, at the moment, we haven't updated about the fourth quarter, We'll give you an update probably in October.
Your next question is from the line of Stephen Volkmann with Jefferies.
Hi. Good morning, guys. My question is on Resource Industries, and I'm curious if you can give us any color in terms of the growing backlog there on kind of machines relative to parts. I'm just trying to think about sort of the mix of that business going forward.
Yeah. Thank you, Stephen. As we've mentioned over the last few quarters, we're bullish on the trend in mining. We're seeing robust quotation activity. We are seeing increased orders. We talked about autonomy already this morning. We have seen certainly strength in aftermarket for mining, but we also see strength in OE as well. Again, as utilization improves, as the energy transition drives higher commodity prices, that is driving activity for us in both parts and OE.
Your next question is from the line of Ross Gilardi with Bank of America.
Yeah, good morning, guys.
Morning, Ross.
Morning, Ross.
Jim, I just had a question just on pipeline activity in general. There seems to be pretty limited new pipeline activity despite the run-up in energy prices. Would you agree with that, and are you seeing that across your business? Maybe just talk about what you're seeing with Solar and with construction equipment and anything else as it relates to pipeline activity. Just comment on the choice not to raise prices in E&P despite cost pressure. Is there just too much excess capacity out there to risk losing market share in the second half? Thanks.
Thank you, Ross. As I mentioned earlier, we do expect our customers are displaying capital discipline, and we expect that to continue. In terms of pipeline activity, our business, I believe, was actually up in the second quarter. That is one data point. Again, we'll see how the future unfolds here in terms of oil and gas. We do feel good about a gradual turn in that business. Oil prices are supportive of investment, again, our customers are displaying that capital discipline. There was a lot of strength in natural gas pipelines for a few years, and that tends to be a cyclical business. If you look back over the last 30 years, just in my experience, you go through periods of very strong activity followed by periods of lower activity. Again, it's a cyclical business that goes up and down.
For our business, we did see an improvement in the second quarter in pipeline versus the first.
Specifically on the price increase side, just given that the nature of the recovery within E&T is slightly different from where we're seeing in CI and RI where there's obviously much stronger underlying demand signals. If you saw in the quarter, machines, sales to users, end-user sales were up 20%, E&T was up 1%. They are in slightly different places, and therefore it is a very logical decision to actually take the view that obviously you don't want to put at risk the recovery within the E&T markets, so we will take a little bit of pain on price in the short term. Obviously within our construction businesses and within RI, we do expect overall price to more than offset manufacturing cost increases.
Just remind you, in manufacturing costs, significant amount of that is actually a step increase, which we would not price for as well, and some of that is also going to impact E&T.
Your next question is from the line of Mircea Dobre with Baird.
Thank you for the question. Good morning, everyone.
Morning.
Just looking to make sure that I have this straight. It sounds to me that you expect revenues to be up sequentially in the third quarter relative to the second, based on your end-user demand commentary. In terms of the margin moderating sequentially, it's pretty clear that this is going to be the case with Energy & Transportation. Will the other segments see a similar dynamic? If so, can you help us understand kind of moving pieces and why? Thank you.
Overall, as we've indicated, we do expect the third quarter to be strong. Effectively, the rate of growth of STUs will be higher in Q3 than Q2. We don't give specific guidance on absolute revenue numbers, obviously we're giving you a little bit of color there. As far as the margin, yes, E&T will moderate. That's an impact, as we said, of not putting price through. Within CI and RI, within the machines businesses, obviously we've seen price benefit. Part of that price benefit is geo mix. Geo mix will come off a little bit, there'll be an offset between geo mix and price. That's really due to the mix of sales between the different geographies, which impacts geo mix.
Price won't improve, obviously you will start seeing some material cost increases and probably some increasing freight costs, based on what we're seeing in the market today. That will be where the margin pressure is on the machine side, both CI and RI. In addition, obviously, as I said, we do expect some increases in the underlying SG&A and R&D spend as the return to work normalizes and some of the things like travel start opening up, and we start seeing some of those expenses come back.
Your next question is from the line of Jairam Nathan with Daiwa.
Hi. Thanks for taking my question. I just wanted to kind of try to get your strategy on batteries and fuel cells. Recently, I think Wabtec announced an agreement with GM where they will be sourcing GM's fuel cells. I just wanted to understand what your strategy is on that. Would it be more internal or would you be open to external sourcing?
Thank you, Jairam, for your question. You may recall that we introduced last year the first zero-emission switch locomotive, and we sold that to a couple of customers, something we're excited about. We're very flexible and we will do certain things ourselves. We'll do certain things with partners and suppliers. Again, those discussions are ongoing and we'll come up with, as we do with all of our products, some things we'll make ourselves, some things we'll get from suppliers, some things we'll get from partners, and we're working our way through that.
Your next question is from the line of Stanley Elliott with Stifel.
Hey, good morning, everyone. Thank you for taking the question. Quick question around infrastructure and the timing of when you all will see that. Certainly lots of discussion here in the U.S., but really elsewhere. Those monies take some time to flow through the system. Do you end up seeing end market demand pick up ahead of that and more concurrent with it? Just trying to get a frame from when we could see that benefit. Thanks.
Thank you for your question. We already are seeing stronger heavy construction activity. It's something we saw in the second quarter. We expect that improvement to continue. That is irrespective of an infrastructure bill in the United States being passed. We're seeing improvement in that business. It's being driven by a whole variety of things. If in fact there is an infrastructure deal, always difficult to estimate timing. Typically, that helps the confidence of our customers, which helps our business. We are already seeing an improvement in our heavy construction activity. Again, we expect that strength to continue moving forward regardless of a deal or not.
Your next question is from the line of Ann Duignan with JPMorgan .
Yeah. Hi, good morning.
Good morning.
Maybe just back to your comments on the geographic mix in CI and RI being negative. I don't maybe fully understand the CI comment given the strength you're talking about in North America and in particular just your comment on the non-res sector. RI maybe.
Geographic mix, I can appreciate that. Maybe you could just walk us through the comment on the negative mix in both of those segments as we go forward?
Sorry, Ann, if I did confuse you in that. Hi. It's actually not negative, but it's sequentially lower, the benefit of geo mix. Most of that is, obviously, if you remember last year, when we looked at geo mix, there was a big move between, obviously, China in the second half of the year was very strong recovery. The U.S., we saw dealer inventory reductions and softer demand. There was a negative drag on geo mix. First quarter, obviously China was very strong in CI. The U.S. slightly weaker. Obviously now in the second quarter, we've seen that turn around quite significantly, and that gave us a big benefit of geo mix in Q2. That will moderate because the relative gap of North America versus the other geographies will actually diminish.
That's how it works, and that's why we think it will actually still be a benefit, but will be less positive than it was in Q2. However, we do expect the price increases that we put through to offset that, so we'll see how the price realization mitigate that impact.
Your next question is from the line of Nicole DeBlase with Deutsche Bank.
Yeah, thanks. Good morning, guys.
Morning, Nicole.
Morning, Nicole.
Can we just talk a little bit more about what's going on in China construction, I guess, what's driving your confidence in a flat outcome for the year, given the tough comps throughout the rest of the year? Also if you could talk a little bit about what you're seeing from a pricing perspective in that market. Thank you.
You bet. Just as a reminder, last year was a very strong market in China, very strong. We saw a very strong first quarter this year as well. We did see the industry decline modestly in the second quarter, and that's, again, as we expected, and I think some policy normalization there drove that weakness. Just based on everything we see, we are expecting the full year to be roughly flat to last year. As a reminder, that's a very healthy level because last year was so strong. That's what we see. I mentioned earlier about the fact that our GX models have been well received. We're very pleased at that product introduction. It is a competitive market. You asked about pricing.
It's a competitive market, but again, by introducing new products, by continuing to build out our dealer network, we're confident in our ability to continue to be able to compete in China.
Your next question is from the line of Joel Tiss with BMO.
Hi. Thanks for giving me a chance here. Can you give us an idea how much dealer inventory is needed to get back to more normalized levels? I know it's a moving target, and also is that more of a catching up in 2022, or the way things look today that some of that might leak into 2023?
Joel, thanks. This is Andrew. As we said, we expect this year not to see any significant benefit from dealer restocking. Our prioritization, given some of the supply chain challenges, is absolutely meeting end user demand. We need to see how things pan out in 2022. We will always prioritize making sure that we are meeting end user demand over increasing inventory in the dealer channel. That will be something we will continue to work with our dealers on, making sure that they do it. It's way too early to predict when dealer inventory will rise. We'll continue to monitor that, and we'll update you as we go through every quarter.
Your next question is from the line of Noah Kaye with Oppenheimer.
Good morning, everyone. This is Kristen on for Noah. Thank you for taking our question. Wanted to follow up on the mining activity and some of the quoting that you talked about. You indicated that is driving that strength more than mining. Just given commodity basket near historic highs, the high utilization that you talked about, conditions seem really ripe for a significant mining up cycle. As you talk to your customers, what's holding the end market back at this point, and when do you think that spending breaks loose? Thank you.
Morning, Kristen. Thanks for your question. As we've been discussing for several quarters, mining, we've been bullish on the long-term trend in mining, and we are seeing an improvement in that business. It does tend to be lumpy, but again, the trend is quite positive. I wouldn't say anything is holding it back. It's really manifesting itself much as we've been predicting for the last three or four earnings calls, a steady improvement in mining, and it's continuing to happen. Again, a lot of quotation activity. Our customers are always very focused on capital discipline. Having said that, utilization is high. Parked trucks are low across all regions. Commodity prices, as you indicated, are quite strong. It's turning out as we expected, which is a steady gradual improvement in mining, and we're very pleased at that.
Honestly, that kind of a profile I think is better for everybody than a spike ups and then a drop and a spike up and a drop. We love to see that steady improvement.
Your final question for today comes from Chad Dillard with Bernstein.
Hi. Good morning, guys. Thanks for squeezing me in.
Hi, Chad.
Hi, Chad. Good morning.
A couple questions for you. First, more near term, can you quantify the material and freight costs for about the second half in 2021?
Longer term, can you just talk about your conversations with mining customers on electric drive equipment? By when do you think there's broader adoption? What are you thinking in terms of parts intensity versus internal combustion? What, if any, new revenue streams could there be from that transition?
Yeah. Obviously, I do not give a guidance on what we think the cost will be. As we said, we do think they will be higher in the second half. Again, just to remind you, price will be about the same. We expect for the full year, full machines or price to more than offset increases in manufacturing costs. That increases in manufacturing costs also include short-term incentive compensation, which again, is not only higher versus last year, but is also above our baseline level given the results we have. It is a moving part. There's lots of bits of moving parts within there. Absorption rates have an impact and so forth as well. Overall, though, yes, they are increasing, they are a pressure. However, probably it's more that we saw such strong favorability.
Remember Q1, we actually had material costs, manufacturing costs were favorable. Also we saw a very minimal price. We saw stronger price in Q2, and a small increase in manufacturing costs. That just means that the manufacturing costs will get greater and more mitigate, offset some of that price we've seen. That gives you a sort of range to work to.
In answer to your mining question, we're working very closely with our customers to help them achieve their sustainability goals. There's a wide variety of different approaches, as you can imagine, between from customer to customer, but also from geography to geography as well. So there's no one answer to that. Again, we're working very closely with our customers. Announcements will be made at the appropriate time. We had one at NMG this quarter. It's just an example of some of the things that we're doing to support our customers. So again, those adoption rates will vary geographically and by customer.
Okay, with that, we'll conclude our Q&A session. Now let me turn the call back over to Jim Umpleby.
Well, thanks everyone. Really appreciate you joining the call this morning. Thank you for all your questions. We continue to focus on executing our strategy for long-term profitable growth, which as you recall, includes services, expanded offerings, and operational excellence. Congratulations to our team. We had a strong quarter. We're pleased that there's strengthening in demand coming from all regions. We're optimistic about our ability to solve the challenges that arise and also to continue supporting our customers as they move forward. Thank you again.
