Andrew R.J. Bonfield
Chief Financial Officer at Caterpillar
Thank you Jim and good morning everyone. I'll start on slide 9 with my thoughts on Caterpillar's third quarter results, including the performance of each segment. Then I'll turn to the balance sheet and conclude with a few assumptions about the fourth quarter and full year. As Jim noted, our sales and revenues for the third quarter rose by 25% or $2.5 billion to $12.4 billion. This was primarily due to higher volumes. Operating profit increased by 69% to $1.7 billion. Third quarter profit per share was $2.60 compared to $1.22 in the third quarter 2020. Adjusted profit per share increased by 75% to $2.66 compared to $1.52 last year.
Turning to slide 10, third quarter sales and revenues grew by double-digit percentage points for the three primary segments. Volume gains were the main growth driver with higher sales to users leading the way. In addition, dealer inventory provided a tailwind declining by $300 million this quarter versus a $600 million decrease last year. Services revenues, favorable price and currency also contributed to the topline gain. Looking at it sequentially, sales in the third quarter were around 4% lower than in the second quarter, which is in line with normal seasonality. Third quarter sales and revenues increased in every region.
In North America, our largest region sales increased by 28% with strong growth in all three primary segments. In EAME, sales rose by 23% as infrastructure spending supported higher demand. Latin America sales grew by 72% from a low base. Asia-Pacific sales increased by 8% with gains in Resource Industries and Energy and Transportation more than offsetting lower revenues in Construction Industries. As Jim mentioned, China was a bright spot in the third quarter of 2020 so the decline in construction industry sales in China was in line with our expectations. As usual, we have separately reported our quarterly sales to users.
Globally, sales to users increased by around 14% versus the year ago. As Jim previously commented, the 14% growth rate was below our expectations, primarily due to supply chain constraints. Sales to users in Construction Industries rose by 12% with double-digit growth in North America, EAME and Latin America. Asia-Pacific sales to users declined by 10%, reflecting the expected moderation in China, following the strong growth earlier this year. We still anticipate that the above 10 ton excavator industry will be about flat for the full year when compared with the -- to last year's very strong performance.
Sales to users rose by 33% in Resource Industries. Growth was consistent across the segment as both mining as well as heavy construction and quarry and aggregates saw strong gains. In Energy and Transportation, sales to users increased by 8% reflecting gains in industrial and oil and gas applications, partially offset by reductions in both power generation and transportation. Now, let's review the bottom line on slide 11. Third quarter operating profit increased by $679 million or 69%. The higher volume was the principal driver of the increase in operating profit for the quarter. Volume gains and favorable price realization were partly offset by higher SG&A, R&D and manufacturing costs, which included both short-term incentive compensation expense as well as higher material and freight costs.
Year-over-year, the adjusted operating profit margin rose by 260 basis points to 13.7%. Versus the second quarter, the adjusted operating profit margin declined by about 40 basis points, which was slightly better than we had anticipated. The main reason was a stronger gross margin due to better price and slightly lower material costs than we had expected. Our global effective tax rate for the third quarter was 25% versus the 26% we had assumed previously. Restructuring expenses of $35 million decreased by $77 million compared to last year. Adjusted profit per share of $2.66 was higher than we expected reflecting strong operational performance, as well as the lower than expected global tax rate and discrete tax benefits.
These accounted for about $0.14 per share in aggregate for the quarter. We also saw some currency benefits from hedging in the quarter, primarily related to the euro. Moving to slide 12, let's take a look at segment performance, starting with Construction Industries. Sales increased by 30% in the third quarter to $5.3 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 of changes in dealer inventories. The increase in end user demand was led by North America where non-residential construction demand continued to improve and we also saw continued strength in residential construction.
Overall, dealers reduced their construction equipment inventories less in the third quarter 2021 than they did in the third quarter of 2020. The segment's third quarter profit went up by 47% to $859 million. The increase came from higher sales volume and favorable price realization. This was partially offset by unfavorable manufacturing costs, which largely reflected higher freight and material costs. The segment's operating margin increased by 190 basis points versus last year to 16.3%. Turning to slide 13, Resource Industries sales increased by 32% in the third quarter to $2.4 billion. The improvement was mostly due to higher end user demand for equipment and aftermarket parts in both mining, as well as heavy construction and quarry and aggregates.
This was partially offset by changes in dealer inventories. Third quarter profit for Resource Industries increased by 78% to $297 million. The increase was mainly due to higher sales volume and favorable price realization, partially offset by higher freight and material cost. The segment's operating margin at 12.3% increased by 310 basis points when compared to 2020. Now on slide 14, Energy and Transportation sales increased by 22% to approximately $5.1 billion. That included a 48% sales increase in oil and gas, which came off a low base and also included the addition of SPM Oil & Gas. Here we saw higher sales in both reciprocating engines and turbine.
Power generation sales declined slightly as turbines and related services were unfavorably impacted by the timing of customer projects. Industrial sales rose by 30% with demand higher across all regions. Transportation rose by 12% off a low base on higher rail services and marine sales. Profit for Energy and Transportation increased by 41% to $696 million. The improvement reflected higher sales volume that was partially offset by a couple of factors: unfavorable manufacturing costs, including freight and material, the impact of short-term incentive compensation and acquisition-related expenses, primarily SPM Oil & Gas.
Keep in mind that the third quarter of 2020 included an unfavorable impact from inventory write downs and asset impairments. The segment's operating margin increased year-over-year by 190 basis points to 13.7%. As we mentioned last quarter, we do expect to SPM Oil & Gas to modestly impact margins with Energy and Transportation this year as it will take some time for the synergies to be realized. We remain very pleased with how the integration is going and expected to see the full benefits of the transaction as we move forward. On slide 15, Financial Products revenue increased by 5% to $762 million. Segment profit increased by 22% year-over-year to $173 million.
The year-over-year profit increase was partly due to favorability in returned or repossessed equipment as demand for used equipment remains very strong. We also benefited from a lower provision for credit losses along with a higher net yield on average earning assets due to a favorable change in weighted average interest rates. These benefits were partially offset by the impact of higher short-term incentive compensation expense. Our credit portfolio remains in good shape as customer health indicators are positive. Past dues continue to improve across all portfolio segments to 2.41%. That's down 140 basis points year-over-year and down 17 basis points compared to the second quarter.
This is below our 10-year average. New business volume also continued to improve. In fact, the third quarter of 2021 was the highest new business volume in the third quarter for 10 years. On slide 16, ME&T free cash flow was $837 million in the quarter, slightly lower than we saw in the third quarter of last year. Higher profits were partly offset by a $1 billion increase in Caterpillar inventory in the third quarter compared to the second quarter of 2021. The growth in Caterpillar inventory reflected an increase in production inventory due to shortage of certain components and higher end user demand.
The company ended the quarter with $9.4 billion in enterprise cash. We continue to maintain a solid liquidity position as we prioritize a strong mid-A credit ratings. ME&T has generated free cash flow of $4.2 billion year-to-date. We said at our 2019 Investor Day that we intended to return substantially all of our ME&T free cash flow to shareholders over time using a combination of dividends and share repurchases. We've repurchased about $1.4 billion of our common shares this quarter, which brings the total to $1.6 billion year-to-date. We paid a dividend in the third quarter of $1.11 per share or about $600 million in aggregate reflecting the 8% increase we announced in June.
Through the end of the third quarter we've returned $3.4 billion to shareholders through dividends and share repurchases. Now on slide 17, in light of the highly fluid environment we'll continue not providing guidance for our annual profit per share. To assist you with your modeling, we'll continue to share some high level assumptions for the upcoming quarter. We expect a stronger top line in the fourth quarter compared to the third, which would follow our normal seasonal pattern. As we said before, we do not expect a significant benefit from dealer restocking in 2021. We expect our adjusted operating profit margin in the fourth quarter to generally follow the seasonal pattern of lower margins versus the third quarter.
Sequentially, we see continued pressure from higher material and freight costs, which accelerated during the quarter and are likely to remain elevated in the fourth quarter. We anticipate this will be partly offset by price realization. We continue to expect price to offset higher manufacturing costs for machines in 2021 although further disruptions in the supply chain can make that more difficult. As we said previously, price realization will not offset manufacturing cost within Energy and Transportation. But as the fourth quarter is typically a stronger sales quarter in this segment that will help its overall operating margin.
As Jim mentioned, based on our results to-date we continue to anticipate meeting our Investor Day target for adjusted operating profit margins in 2021 despite the nearly 300 basis points of pressure from reinstating the short-term incentive compensation program. We currently anticipate 2021 restructuring expense of $150 million to $200 million compared with our previous estimate of $350 million. This compares to restructuring expenses of $354 million in 2020. We now expect the global effective tax rate for the year to be 25%, down from 26% earlier. We anticipate capital expenditures for the year of about $1 billion to $1.1 billion versus our previous estimate of $1 billion to $1.2 billion.
We also continue to anticipate reaching our target for ME&T free cash flow in 2021. Turning to slide 18; in summary, demand remained strong and we performed well in the quarter that presented additional complexity due to the challenges within the supply chain. Our operating performance was strong with sales up 25% and adjusted profit per share up 75% versus the prior year. We remain on track to meet our Investor Day targets for adjusted operating margins and free cash flow to the year.
With that, we'll now take your questions.
