John D. Romano - Co-CEO & Director
Thanks, Jennifer, and good morning, everyone, and thank you for joining us today. I'll start this morning by setting the stage with a quick overview of Tronox. We are the world's largest vertically integrated TiO2 producer with 9 pigment plants, 6 mines, 5 upgrading facilities across 6 continents.
Our 2021 revenue totaled approximately $3.6 billion, which was fairly evenly distributed across the Americas, Europe, Middle East and Africa and Asia-Pacific. Our 1.1 million tons of pigment capacity supports our well-balanced space of approximately 1,200 global customers. Our vertically integrated business model supplies approximately 85% of our internal feedstock needs, and this ensures consistent and secure supply for our customers. In addition to TiO2, we also generate significant value as the world's second largest producer of zircon, with approximately 297,000 tons of capacity.
We are proud of the organization we created following the transformative acquisition nearly 3 years ago and the value we have and will continue to generate for our stakeholders.
Now let's turn to Slide 5 for some of the highlights. 2021 was a record year for Tronox on a number of measures. During the year, we maintained our strong execution and delivered on our commitments to all of our stakeholders. Our record revenue of $3.6 billion was driven by robust customer demand and our ability to meet this demand with our unmatched global footprint. Our adjusted EBITDA of $947 million and margin expansion to 26.5% is attributable to our vertically integrated business model, a primary driver of our lower integrated cost per ton.
Improved pricing across all product lines and cost savings through programs such as newTRON offset higher commodity and freight costs. In 2021, we invested just over $270 million in key capital projects. This included newTRON, our project to digitally transform our global portfolio, which is expected to meaningfully reduce production costs by $150 to $200 per ton on a run rate basis by the end of 2023. We're pleased with the progress we're making, and we're tracking to our plan. We also invested in Atlas-Campaspe, our mining project in Eastern Australia to maintain our advantaged vertically integrated position as it will replace our Ginkgo and Snapper mines.
We generated a record $468 million in free cash flow from our strengthened and differentiated business model, allowing for deleveraging ahead of our targeted objectives. We paid down $745 million of debt in 2021, ending the year at $2.6 billion with a net leverage of 2.5x ahead of our previously stated time line of achieving $2.5 billion in gross debt and 2 to 3x net leverage by 2023.
We plan to continue to pay down debt beyond our previously stated targets to ensure our business remains well-positioned to withstand a range of economic scenarios. And last but certainly not least, we continued our progress towards achieving our sustainability goals that we published in 2021, including another solid year from a safety performance perspective, thanks to the unrelenting focus by our employees.
Turning to Slide 6, I'll review our sustainability accomplishments for 2021 in more detail. In 2021, we made significant strides forward on our ESG efforts. In July, we formalized our commitments to align with a global warming scenario of below 2 degree centigrade and set a target of net 0 greenhouse gas emissions and 0 waste to external dedicated landfills by 2050, as well as other ESG-related commitments such as targeting 0 workforce injuries.
Additionally, Tronox joined the United Nations Global Compact. We mapped our long-term targets to the UN sustainable development goals and committed to the 10 principles. Incorporating the UN standards into our strategies and procedures will help us protect our privilege to operate and set the stage for long-term success.
In August, we announced the reorganization of our Board committee structure to enhance our oversight of our ESG efforts. Most recently, we achieved a platinum rating by EcoVadis, the highest level of recognition awarded and a validation of our efforts. This represents a significant improvement over our silver rating in 2019 and 2020 and puts Tronox at the top 1% of companies evaluated. The step change in our 2021 rating reflects how deeply embedded sustainability and corporate social responsibility have become in our business practices and the advancements we've made in our public disclosure on these topics.
Additionally, we've committed to be fully compliant with the applicable TCFD and SASB disclosure standards when our next sustainability report is published by midyear. While sustainability has long been a part of everything we do at Tronox, we remain committed to continuous improvement and further enhancing how we disclose our progress and efforts.
Turning to Slide 7. I will briefly review our full year financial highlights before turning to the fourth quarter review. Revenue of $3.6 billion represented a 30% increase versus the prior year. Income from operations of $577 million grew 113%, while net income of $303 million was lower due to a tax benefit of $903 million in 2020 that did not repeat.
Our effective tax rate in 2021 was 19%. Our GAAP diluted earnings per share was $1.81 and our adjusted diluted earnings per share was $2.29, more than 300% higher than 2020. Adjusted EBITDA of $947 million represented a 42% increase over 2020 and our margin increased 230 basis points. Free cash flow of $468 million increased 200%.
Now turning to Slide 8, let me provide more detail into our fourth quarter. Our fourth quarter results came in line with our previously issued guidance. Revenue in the quarter increased 13%, driven by higher average selling prices. Sequentially, this represented a 2% increase. Our effective tax rate in the quarter was 16%, and our net income for the quarter was $87 million, a 53% improvement. Diluted earnings per share was $0.52 and adjusted diluted earnings per share was $0.53, an improvement of 179%. Adjusted EBITDA of $233 million improved 14% and our adjusted EBITDA margin was 26.4%, and we generated free cash flow of $50 million in the quarter.
Moving to Slide 9. I will now review our fourth quarter commercial performance in more detail. Our fourth quarter results were in line with our expectation with our team managing strong customer demand while navigating a number of macro challenges, including input cost inflation and supply chain disruptions.
Total revenue increased versus the prior year as higher selling prices were partially offset by lower feedstock and other volumes and the unfavorable euro exchange rate. TiO2 revenue of $675 million increased 15% versus the prior year due to higher prices across all markets. Volumes were flat year-on-year and lower by 4% versus the third quarter within our anticipated and communicated range. The TiO2 supply/demand balance remains tight due to continued strong demand, while TiO2 inventories remain well below seasonally normal levels and delivery times are extended by shipping delays and supply chain disruptions.
Zircon revenue increased 26% versus the prior year due to continued pricing momentum as volumes were in line with the strong volume levels in Q4 of 2020. Sequentially, zircon volumes were lower due to higher sales from inventory in the third quarter. In 2022, Zircon volumes will be more in line with production as we have sold the excess inventory out of the system. Feedstocks and other products declined due to the internalization of all feedstock sales in the quarter compared to the prior year, partially offset by increased pig iron revenue from higher average selling prices. On a quarter-over-quarter basis, the increase in revenue was driven by higher pig iron pricing.
JF and I are grateful to the approximately 6,500 global employees whose dedication, perseverance and ingenuity allowed us to deliver outstanding performance in spite of numerous external pressures. We're working tirelessly with our dedicated team of employees to ensure we are the supplier of choice for our customers. By leveraging our unmatched global footprint and our vertically integrated business model, we remain well-positioned to continue managing through and overcoming these challenges.
Our global footprint positions us close to our customers, while vertically integrated business model ensure security of supply. Customers are increasingly recognizing our reliability as a differentiator, which is a significant advantage. For example, in 2021, we were able to substantially increase the number of long-term volume contracts with our global customer base, securing our market share well beyond 2022. We anticipate TiO2 market demand to grow in line with GDP in '22 and will be supported by the need to replenish inventory throughout our customer supply chain channels.
In the first quarter, demand is expected to continue to be very strong. And while distribution remains challenged, we are anticipating the first quarter TiO2 volumes to increase sequentially in the upper single digits as we work to meet our customer needs. Pricing will continue to increase in the quarter and offset recent inflationary pressures to allow for continued margin expansion.
Zircon sales volumes are expected to remain elevated above 2019 and 2020 levels. However, volumes in the first quarter will be lower than those in the fourth quarter, more in line with production levels. Zircon pricing improvement in the first quarter is expected to more than offset the volume headwind on an EBITDA basis, and we expect this trend to continue for the full year.
I will now turn the call over to JF for a review of our operating performance and profitability in the quarter. JF?
Jean-François Turgeon - Co-CEO & Director
Thank you, John. Moving to Slide 10. As John mentioned, our adjusted EBITDA growth of 14% to $233 million was driven by higher average selling price across all products, partially offset by lower volume and higher cost to serve our customers, including increase in raw material, natural gas and freight and unfavorable FX rate.
Freight rates globally have remained elevated, driving increased cost to deliver product to our customer given the need to use non-contracted line to deliver product. In particular, escalating ocean freight rate out of Australia and demurrage expense in South Africa drove incremental costs. Inflation pressure, including both external ore purchase and commodity price, continued to increase in the fourth quarter. On a per ton basis, 75% to 80% of the sequential cost increase was driven by higher process chemical and utility costs. While we saw more favorable movement in the ZAR and Australian dollar in the fourth quarter versus the third, unfavorable impact to revenue from the euro largely offset the majority of these benefits.
Turning to Slide 11. I will review how our strategy will enable us to continue differentiating our business in 2022 and meet our financial target. We remain committed to executing on our strategy to become an advantage vertically integrated global TiO2 leader. Foundational to our strategy is to produce low-cost, high-quality pigment for our customers and sustaining our integrated global footprint to ensure security of supply for our customers and optimize our global footprint.
Our mining and upgrading facility continue to run at high operating rate at a time when feedstock are critical. This, combined with our integrated planning capabilities, will allow us to increase production and produce an additional 40,000 tons of TiO2 this year versus 2021.
Our effort in capital expenditure will continue to be dedicated to pursuing these pillars through projects like newTRON and Atlas-Campaspe. Our strategy drives our ability to leverage our unique portfolio to optimize our assets and secure our position as the most adaptable, resilient TiO2 industry leader, allowing us to continue to deliver industry-leading financial performance.
Turning to Slide 12. I will now provide an update on our key capital projects. If we look at our major strategic capital projects, they can be divided in 2 categories: the first being growth and cost reducing capital; and the second as vertical integration-related capital. newTRON fall under the first bucket. newTRON is our strategic multiyear global digital transformation project. We realized $20 million in EBITDA savings in 2021 due to the benefit primarily in supply chain and procurement savings. In total, we anticipate $150 to $200 per ton annual run rate cost saving by the end of 2023.
The second bucket relates to sustaining our vertical integration. Our business model is our source of differentiation and investing in our mine is critical in sustaining that advantage. Atlas-Campaspe has represented the next phase of our mining plant. And this year, we had the Namakwa and Fairbreeze extension to our investment. Atlas-Campaspe, as a reminder, is our new mining development in Eastern Australia that is expected to come online in the second half of 2022 to replace the Snapper/Ginkgo mine as they reach end of life. These elements are abundant in natural rutile, high-value zircon and high-grade ilmenite suitable for synthetic rutile slag processing or direct pigment production. The investment in Atlas-Campaspe will also put in place the infrastructure for this new mining area where we have other important future resource in our portfolio.
Additionally, given significant market demand for TiO2 and our anticipated production growth, we will also be pulling forward the expansion of 2 of our mine in South Africa, Namakwa and Fairbreeze to ensure sustained production in 2024 and 2025. They are similarly rich in ilmenite, rutile and zircon and will extend our mine life in South Africa well beyond 2035. In total, we anticipate investing approximately $150 million in 2022 across our mining projects, which will sustain Tronox 85% internalization of feedstock, supporting approximately $300 per ton saving relative to average high-grade feedstock market price.
Turning to Slide 13. I would like to spend a bit more time on the various elements of newTRON and provide examples of why this project is so transformational for Tronox. newTRON will transform our business, enabling us to remain among the lowest cost TiO2 producer and enhance service to our customer. We will achieve this through an optimized global supply chain, efficient maintenance spend, enhanced automation and throughput and standardized process.
As an example of an optimized global supply chain, our new vendor management system allows improved handling of catalogs, purchase order and invoice, enabling the optimization of our sourcing activity globally. As an example of enhanced automation, we have seen significant stabilization in our chlorinator at Stallingborough as a result of program being trialed today. This has increased the uptime of the plant and has also led to reduce coke consumption. We are very excited about the initial results and what this means for Tronox future.
Efficient maintenance mean our plant employees have improved capabilities to plan and schedule maintenance before equipment failure to optimize production schedule and downtime. The standardization across our function will lead to improved visibility and a streamlined order to delivery process, enabling better data visibility and decision-making. It also facilitates the transfer of best practice from one side to another. We anticipate $150 to $200 per ton cost saving by the end of 2023 will come from all 4 of these areas with clearly identify benefit.
Finally, I'd like to provide a brief update on our slagging operation in Jazan. The first slag was stacked at the end of November. The ramp-up is progressing according to plan. Slag has been shipped to Yanbu pigment plant for use this quarter. At a time where tight feedstock conditions are impacting the TiO2 industry, Jazan is a clear advantage and an important part of Tronox's vertical integration strategy. The site will continue to ramp-up from here forward, ensuring a safe and sustainable operation. As a reminder, slag production must reach sustainable operation before Tronox will assume ownership of the site. Based on the current plan, the site could achieve sustainable operation in the second half of 2022. We will continue to update the market on the progress of the site.
I will now turn the call over to Tim Carlson to cover our balance sheet and outlook. Tim?
Timothy Craig Carlson - Senior VP & CFO
Thank you, JF. On Slide 14, we provide an overview of our financial position, liquidity and capital resources. We ended the year with net leverage of 2x to 5x, down from 4.1x at the end of 2020 and within our previously stated targeted range of 2 to 3x. We reduced our debt by a total of $745 million in 2021, ending the year with $2.6 billion, a significant reduction from the $3.3 billion balance at the end of 2020. Total available liquidity as of December 31 was $677 million, including $228 million in cash and cash equivalents, which is well distributed across our global operations.
Capital expenditures totaled $272 million in 2021. Approximately $120 million of this was for maintenance and safety capital. $56 million was for project newTRON and $97 million was for operational vertical integration projects, which included Atlas-Campaspe. Depreciation, depletion and amortization expense was $297 million for the year. Our free cash flow totaled $468 million due to our strong cash earnings. We also returned $65 million to shareholders in 2021 in the form of dividends year-to-date, which we increased by a total of 43% on an annualized basis.
Turning to Slide 15. I'd now like to share our outlook. As John mentioned, we anticipate strong demand trends to continue for both TiO2 and zircon in addition to continued supply chain disruptions and inflation pressures, including elevated commodity pricing. Due to these ongoing cost pressures, we expect first quarter adjusted EBITDA to be $230 million to $245 million, driven by higher cost of goods manufactured in the fourth quarter, impacting our results in both the fourth and first quarters as those tons are sold. This trend is expected to reverse beginning in the second quarter as we've seen favorable manufacturing cost per ton in the first quarter versus the fourth, in addition to improved TiO2 and zircon pricing.
For the full year 2022, we are reinstating our practice of providing annual guidance on the following metrics. We expect 2022 to be the year we meet and exceed our ambitious $1 billion EBITDA target as we expect margins to expand throughout the year. Full year adjusted EBITDA is expected to be between $1.025 billion and $1.125 billion. Reported diluted EPS is expected to be between $3.02 and $3.52 per share.
Adjusted diluted EPS is expected to be between $3.08 and $3.59 per share, and we anticipate generating at least $400 million in free cash flow. Incorporated into our free cash flow assumptions are the following uses of cash. We expect working capital to be a use of $75 million to $100 million as we begin to rebuild inventories to more normalized levels. Net cash interest expense of $120 million to $130 million, $45 million to $55 million of cash taxes and capital expenditures of $375 million to $400 million.
These represent our best estimates based upon our current outlook. However, this does not represent a ceiling for our potential. We have significant runway ahead and expect to see earnings expansion driven by growing the top line, reducing our cost per ton through high-return capital projects remain focused on disciplined expense management and leveraging our tax attributes. The record financial results of 2021 are evidence of our strengthened and differentiated business model, and we're confident this will continue to distinguish Tronox in 2022 and beyond.
Turning to Slide 16 with respect to capital allocation. With our $2.5 billion gross debt target in site, we expect to prioritize capital expenditures, continued annual build increases. We continue reducing debt while opportunistically repurchasing shares. For 2022, we estimate capital expenditures will be between $375 million and $400 million. Our maintenance and safety capital will be approximately $125 million. Investments in sustaining our vertical integration will be approximately $150 million, inclusive of Atlas-Campaspe in the mining extensions in South Africa. Growth in cost reduction projects will total $100 million, the majority of which will be for project newTRON and other smaller strategic projects will total approximately $25 million.
We estimate our average annual returns on total capital expenditures to be between 25% and 30%. As announced in November, we anticipate increasing the dividend to $0.50 per share on an annualized basis, beginning with our first quarter dividend, and we anticipate continuing to reduce our debt below the previously stated target of $2.5 billion, while opportunistically buying back shares under the $300 million program authorized by the Board.
I'll now turn the call back over to JF for closing remarks.
Jean-François Turgeon - Co-CEO & Director
Thank you, Tim. Moving to Slide 17. As we wrap up today's prepared remarks, I want to take a moment to acknowledge the outstanding position Tronox is in. Due to the commitment of our employees throughout the last several years, this would not be possible without them. So thank you to everyone for your ongoing efforts.
With our portfolio of assets and market position, we are confident in our ability to capitalize on our momentum, execute against our objectives and deliver our commitment to our stakeholders. 2022 is an exciting year for Tronox. We are planning to hold our second Investor Day in June and look forward to presenting the market with more details on our long-term strategy, our key operational and financial aspect of the business, ESG-related practice and more. We will provide additional logistic detail at a later date. We continue to navigate the current macroeconomic challenge while transforming our company, which will ensure our future remain bright.
That concludes our prepared remarks. With that, I'd like to turn the call over for questions. So Jason?
Operator
(Operator Instructions) Our first question comes from John McNulty from BMO Capital Markets.
John Patrick McNulty - Analyst
So when we look at the outlook that you have for 2022, there's a heck of a ramp-up from the 1Q levels to kind of the latter part of the year. So I guess, can you give us -- can you speak to your confidence around the improvement on the manufacturing cost and how that plays into the guide throughout the year? And then -- and maybe give us some examples around it? And then also, how should we think about what it means for pricing in terms of what your assumptions are as we kind of roll through the year?
John D. Romano - Co-CEO & Director
Yes. Thanks, John. I'll start that, and then I'll let Tim add a little color to it. So when you think about the first quarter, that's one of the reasons we reinstated the annual guidance so that you guys could get full confidence that we're confident that we can actually recover from where we are in the first quarter.
The first quarter number is impacted really by 3 things. You can put it in 3 buckets: Energy and process chemicals; planned maintenance that impacted fixed cost absorption in the fourth quarter, which had an impact on our cost. And then volumes that rolled from the fourth quarter into the first quarter, and I'll touch on that, and then I'll let Tim pick up on the other 2 pieces.
So in the first quarter, we were successful in increasing our prices across the board in every region. But we had significant volume that rolled out of the December shipments into the first quarter, predominantly in January, which came in at that lower price, which had an impact on the revenue and the margin that we were able to capture, but it was only because of the volume rule, had nothing to do with our ability to increase the price.
Tim, why don't you touch on the other 2 buckets?
Timothy Craig Carlson - Senior VP & CFO
Yes, John, when we talked during our third quarter call, we talked about an additional expectation of $30 million of additional costs from Q3 to Q4 around natural gas, energy process comes in freight. That actually came in closer to $45 million to $50 million. So those higher cost -- portion of those flowed through in the month in terms of products sold. But a lot of those costs are capitalized in inventory and are going to flow through in January and February.
In addition to that, as part of our normal planned maintenance, we produced 3,000 to 4,000 less tons in Q4 than we normally would. So that's just a higher overhead cost per ton, which again flows into the year. With the increased volumes that we see both from a production and from a demand standpoint, we see that overhead cost trends improving as we go through the course of the year. And as it relates to our natural gas energy process chem costs, we did see those moderate quite a bit as we start the year this year versus Q4. And that, combined with the price increases that John talked about, we're very confident with our margin expansion and with our full year guidance.
John Patrick McNulty - Analyst
Got it. No, that's helpful, really helpful color. And then I guess can you speak to -- you kind of indicated earlier on that inventories are still lean or appear lean. I guess can you give us some granularity as to where you see the inventory levels at your -- between your own and your customer level as we kind of go into the kind of heavier paint season as we kind of kick off in the spring. Like I guess, are we going to be -- is there a chance that we can get back to normal by then? Or is it really going to be a hand-to-mouth kind of situation through most of the paint season this year? How would you characterize it?
John D. Romano - Co-CEO & Director
Yes, John, we're doing all that we can to try to increase our service levels by building that inventory, but the inventory is so depleted throughout the supply chain, not just our inventory, but even our customers' inventory. Quite frankly, we don't have any confidence that we're going to be able to replenish that by the time the coating season starts. We're doing our best to do that. We're repositioning inventory to ensure that we can mitigate some of the transportation issues that we outlined, but the market is still very strong right now, and the supply chain is still pretty depleted.
Operator
The next question comes from Josh Spector from UBS.
Joshua David Spector - Equity Research Associate - Chemicals
I guess just to follow up on maybe the margins and the costs into this year. I mean, you highlighted a lot of the increase was process chemicals utilities, et cetera. Are there any contract resets that happen over the course of this year or next year, either freight, raws, et cetera, that we should be building into our bridge as we look further out?
Jean-François Turgeon - Co-CEO & Director
Well, Josh, it's JF. Look, we have obviously renegotiated most of our contracts like we do as we start the year. And the freight is one where we secure our normal route, but we still have a lot of freight costs that are spot based on customer demand, and we see those freight costs being very high at the moment. And look, it's hard to tell when this will completely change. I mean we assume that that would remain high for whole of the year. Look, there's other things like natural gas and energy that we expect that it will continue to improve in the second half of the year, but I guess time will tell.
John D. Romano - Co-CEO & Director
As we were anticipating, I think, mid-year last year that we'd start to see the transportation issues abate, but we're still having problems, and it's across the board with just availability, although there's a lot of backlog.
Jean-François Turgeon - Co-CEO & Director
It really shows that the economy and everything is moving properly at the moment, and we obviously adjust our own product to reflect that reality. So everything we could control, we do it. I mean the element outside of our control, I mean, we're managed -- we manage it, yes.
Joshua David Spector - Equity Research Associate - Chemicals
Okay. That's helpful. And just curious on TiO2 volumes. I mean, you seem to get pretty bullish outlook, GDP growth. I mean your comments for first quarter is pretty strong growth. Do you see you guys as gaining share? And do you guys grow above that GDP level this year? And I guess related to that, do you have the feedstock kind of aligned to capture those opportunities as you see them through this year?
John D. Romano - Co-CEO & Director
Yes, Josh. So from the standpoint of capturing share, I think what we're doing is maintaining our share, but we've aligned ourselves with customers that we believe are growing faster than the market. So by definition, you could gain share that way. But that's -- we're trying to fill our existing customers' needs.
We noticed -- noted in the prepared comments that we were able to go out and secure significant contracted volume in 2022, which will help us maintain our share well beyond 2022. So our volume uptick in the first quarter has a lot to do with some of the volume that rolled out of the fourth quarter and our ability that we can continue to produce more tons. Last quarter, we told you we were going to produce approximately 40,000 additional tons, and we have the ore that we need to accomplish that goal, and therefore, our sales should continue to grow.
Operator
The next question comes from David Begleiter from Deutsche Bank.
David L. Begleiter - MD and Senior Research Analyst
Just on pricing for this year, how are you thinking about zircon pricing given the strength you saw late in the year? Do you expect that pricing strength to continue through the rest of this year?
John D. Romano - Co-CEO & Director
Yes. So in the prepared comments, we talked a little bit about the volume being down because we've depleted the inventory last year, but price will continue to allow us to grow the EBITDA. So the short answer is yes, we continue to see opportunities to move price. Our first quarter pricing will move up, and we would expect that to continue into the balance of the year as well.
David L. Begleiter - MD and Senior Research Analyst
Very good. Just on TiO2 pricing now it's the subject, but what are your thoughts on maybe yours or industry pricing for this year versus last year?
John D. Romano - Co-CEO & Director
You know what happened last year. And when we think about the first quarter, I would say our pricing is in range, maybe a little higher than what we saw in the fourth quarter. And from the standpoint of how we will continue to progress that price moving into the balance of the year has a lot to do with supply/demand imbalance, which we've just talked about. So we would expect to see pricing continue to move up in 2022.
Operator
The next question comes from Frank Mitsch from Fermium Research.
Frank Joseph Mitsch - President
I was wondering if you could drill down a little more into the ore situation given that you are buying 15% of your needs on the open market. What -- there's a lot of talk about the tightness in the market. I'm curious what your outlook is there. It seems like you anticipate that that's going to continue a while because you're pulling forward some mining expansions as well. But could you give us your take on your situation?
Jean-François Turgeon - Co-CEO & Director
Frank, thank you for the question. And look, obviously, this play to our strength, being vertically integrated at 85%. Look, the 15% that we buy on the open market is long-term contract that we have signed. And the value of having our own mining and upgrading facility allow us to see what's happening on that market ahead of the situation being tied. So we obviously secure ourselves to be in a very good position for 2022. And combined with the success that Jazan is having at the moment, I mean we have more than what we need for 2022 and beyond.
Frank Joseph Mitsch - President
All right. And just a follow-up on the Jazan. It sounded fairly promising that you might actually reach sustainable operating rates in the second half of this year. Where do you see yourselves today in terms of operating rates of that smelter? And you mentioned that some of the ore is being processed by your own facility in Yanbu. How is the quality of that -- of the output at Yanbu using the Jazan material?
Jean-François Turgeon - Co-CEO & Director
So Frank, I think that you have heard me say about Jazan that it's a big experiment. And what I can tell you is, I feel much better today that I felt at our last earnings call because, obviously, we have been produced for the last 3 months. We have elaborated a ramping curve that is cautious for Jazan, and we're following that plant. It's progressing well. We're right on our plan as expected. So that's all good news.
And well, as you know, Jazan is a site with 2 furnaces and it's only furnace 1 that has been modified. And obviously, we need to work on how furnace 2 will be modified so we can reach the full capability of Jazan. So there's still a lot of work to be done on Jazan. But let's say that the timing of starting up this asset is great from the overall market situation.
On the quality of the product, Jazan also use new technology of granulation. And what I can tell you is we were very pleased with the quality of the slag being produced. We don't expect any issue with using that slag. In fact, we have started using that slag and so far, so good. So...
John D. Romano - Co-CEO & Director
No issue at all with the quality of the pigment that's being produced with it. So it's working very well.

The next question comes from Hassan Ahmed from Alembic Global.
Hassan Ijaz Ahmed - Partner & Head of Research
A question -- revisiting the market share question. Look, I mean, I understand that you're not actively out there trying to sort of gain market share in, call it, 2022. But just as I take a look at Q4, your volumes were down 4% sequentially. Some of your larger competitors had a 10% sequential volume decline. Your guidance looking for sort of single digit Q1 sequential volume growth, again, seems to be better than some of your largest competitors out there.
Now in this world that we are living in with extreme sort of ore tightness and from the sounds of it, this sort of tightness in ore supply will continue at least through 2022. Could this be a year where Tronox really breaks away from the pack? And again, I know that you guys aren't looking to gain market share, but just because of the industry dynamics, the way they are and you guys being pretty much the only vertically integrated guys out there, I mean, is it fair to assume that you do far better than the industry volume-wise?
John D. Romano - Co-CEO & Director
Look, so from the -- thanks for the question, Hassan. It's a valid point from the standpoint of our ability to source and produce TiO2 with the ore that we have through our vertical integration. And as we mentioned, we had the capability. We talked about it last quarter of adding 40,000 tons of additional capacity. A lot of that is actually going to come from Yanbu as part of the synergy projects that we had through the transaction that was planned to come online.
So to the extent we have the capability to add additional tons and we have the order to do it, it's possible that we could pick up share, but it's absolutely not being done with price. It's being done with our ability to supply our customers' needs. We made reference to some of those longer term contracts because our customers see the value in the vertical integration and have signed agreements that are based on volume, which give us a good picture on where our market share is going to go well beyond 2022.
Hassan Ijaz Ahmed - Partner & Head of Research
Understood. Understood. Very helpful. And as a follow-up, just a question around where you guys feel we are in the cycle. And I was very intrigued by a statement you guys made on the call and also it's a part of the press release where you said that the 2021 earnings and the guidance that you guys have given does not represent a ceiling for your potential. So that leads me to believe that we're nowhere near the peak, maybe we're at mid-cycle, somewhere slightly above mid-cycle.
And if that's the case, and I take a look at your guidance, your EPS guidance, $3.08 to $3.59, us lazy sell-siders, I mean, we have a tendency of starting a 10x PE multiple on to that, right? So if we are at mid-cycle levels. So from a valuation perspective, that would mean you guys are -- should be somewhere between $31 and $36, which further leads me to believe you're very undervalued. So if you could just help me think through this.
Jean-François Turgeon - Co-CEO & Director
Look, I think, Hassan, what I would say is we're very confident with our outlook for 2022. And look, if you look at our track record over the last couple of years, you would see that, I mean, when we put a range, we deliver on that range. And I can tell you, John, Tim and the whole 6,500 employees are on board to continue to deliver and deliver value to our shareholder related to that.
John D. Romano - Co-CEO & Director
And when you think about where we are with regards to the economic environment, the reality is a lot of the supply chain disruptions have absolutely had an impact on elongating that process. So there'll be -- there's less inventory in the system. We're still trying to replenish the inventory. But it's not just about that. It's also about the cost reduction program. So when we think about -- when we say we still have a lot of runway, $150 to $200 a ton annualized run rate at the end of 2023, you can do the math on 1 million -- 1.1 million tons. That's where we also see a lot of opportunity is in our ability to differentiate ourselves through innovation using newTRON.
Jean-François Turgeon - Co-CEO & Director
Yes. And newTRON also help us to grow with our customers. So -- and I call it the hidden factory. It's really debottlenecking our asset. And as you do that, I mean, you obviously improved their cost per ton significantly.

Our next question comes from Jeff Zekauskas from JPMorgan.
Jeffrey John Zekauskas - Senior Analyst
In 2021, your SG&A expenses, at least as they're stated consolidated income statement went from $347 million to $318 million. Why did they go down, if they went down? And what do you expect for 2022?
Timothy Craig Carlson - Senior VP & CFO
Jeff, it's Tim. Thanks for the question. We have been reducing SG&A. Majority of the reduction over the last couple of years was through the integration of the acquisition that we had with the Cristal transaction. As it relates to SG&A for 2022, we do expect that to be relatively flattish. We do have, obviously, inflationary cost pressures around labor and the like, but we do believe we can offset that with some additional cost reductions. So relatively flattish off that 3.
Jean-François Turgeon - Co-CEO & Director
And some of the improvement obviously, we expect to start traveling a little bit more in 2022 than what we have done in the last couple of years. So that's why even with the benefit of newTRON and some of the benefit, we offset that by higher traveling costs.
Jeffrey John Zekauskas - Senior Analyst
Okay. And early in the call, you talked about having more long-term contracts. Are those only volume-related? Or is there a price component? Or can you describe how the pricing of titanium dioxide for Tronox has changed over the past 2 or 3 years? Or is it the same in the way that you charge your customers?
John D. Romano - Co-CEO & Director
So this is John Romano. From the standpoint, we've talked for a number of years about our margin stability agreement. So let's be clear about the agreements that we signed in 2022. Those were not margin stability agreements. Those were volume-based agreements. And they were agreements that were put together because our customers wanted a long-term commitment for us, which was also good for them. Those don't have pricing limits in them. They have pricing mechanisms, but not limits to what pricing can do. So those are market-based pricing.
Typically, our pricing, on average, you could just say globally, it moves every quarter. We've got some margin stability agreements that have a little bit different mechanisms in them. But the agreements that we spoke about on this call, which are different than the MSA or the margin stability agreements that we have in place, they're based on volume, and those volume contracts are multiyear.
Operator
The next question comes from Matt DeYoe from Bank of America.
Matthew Porter DeYoe - VP
So I think like an annual year worth of inflation is something like $40 million in cost. And on the 3Q call, you had mentioned that would probably double in 2022, just given chlorine and South African electricity prices. But where is that shaking out now? And -- yes, offset there.
Timothy Craig Carlson - Senior VP & CFO
Yes. So Matt, from a cost standpoint, costs are up 21% to 22% much more than that, just given the energy prices are much higher than inflation, sulfuric acid, sulfur price is much higher than inflation. So we are seeing year-on-year cost increases for process chems and energy north of $100 million, offset by obviously the pricing that John talked about, which is going to allow us to continue to expand margins.
Matthew Porter DeYoe - VP
And so if I think about your costs from 4Q, right, you said they were elevated in the quarter, but they're already alleviating in 1Q. Look, I can see the price curve for natural gas in Europe. And so I know it spiked in December and has come off. Is that what you're kind of referring to? Because prices and your costs are still really elevated on a historic basis. So is it just -- you kind of thinking price will stay at these new levels and they're lower quarter-over-quarter? Or do you expect a more seasonal pullback and maybe utility costs as we move through the years?
Timothy Craig Carlson - Senior VP & CFO
Matt, it's a combination of a number of factors. There are a number of costs within our stack that are actually down slightly from a process chem standpoint. But the bigger increases that we talked about in terms of natural gas is exactly moderating, as you mentioned. But we still consider -- continue to see the increases around pet coke and the like -- in sulfur and the like. And in addition to that, with our higher production in the Q1 versus Q4, our overhead cost per ton are coming down.
Operator
The next question comes from Vincent Andrews from Morgan Stanley.
William Tang - Research Associate
This is Will Tang on for Vincent. I'm wondering if you guys could talk about what you're seeing in terms of the local TiO2 supply and demand dynamics in China. Are you still seeing kind of a significant production impact due to the environmental controls there?
John D. Romano - Co-CEO & Director
Yes. So I would say we have a facility over there. Our facility has not been impacted, but there are still some facilities that have been impacted by these dual energy control policies.
When you think about the demand in China, moving out of the fourth quarter into the first quarter, you're always running into Chinese New Year. And this year, the Olympics, I would say, had a little bit more of a dampening effect on demand. Chinese New Year's over, the Olympics will be over the weekend, and we've already started to see volumes pick back up. So if you think about how much demand grew from 2020 to 2021, it was about 800,000 tons, obviously, I'll have a slow base or a low base in 2020. China is continuing to produce, but no more than what we would have expected and in line with the production output that we had actually anticipated.
Jean-François Turgeon - Co-CEO & Director
And Will, one thing I'd add is what we have seen in China is the production of ore has been more impacted by the environmental impact than the production of pigment itself. I think that now they are looking at the impact that some of those mines have and the legacy implication of that, and they force those mine to put better practice and that create price increase. And we see that the ore price in China is at a high level and will remain at a high level and limit really the production in China.
John D. Romano - Co-CEO & Director
Great points. I mean, as recently as this month, the [pandula] ilmenite index went up again along with sulfur. So there's still challenges there.
Jean-François Turgeon - Co-CEO & Director
So that creates a situation where the pigment price in China has to be sold at high value.
William Tang - Research Associate
Got it. And then I guess just looking at your full year guidance, I'm wondering whether the high or low end of that kind of EBITDA range really hinges on where the costs come in? Or I guess what are the other volume and price-related assumptions kind of built in there?
Timothy Craig Carlson - Senior VP & CFO
Yes. So from my perspective, Will, the range in the guidance is really dependent -- not so much on cost just given our ability to pass through price to customers, but it's more in terms of how much volume that we can get out of our plants. We talk about initial 40,000 tons this year. It's possible to do more. And if things happen, it could be a bit less.
John D. Romano - Co-CEO & Director
Yes. It's hard to say. I mean you consider all the disruptions we had in 2021 that we wouldn't have anticipated. I think what Tim is alluding to is that it depends on what happens. A lot of that, I would say, would be things that may be a little more out of our control than in our control with regards to some of the supply issues.
Timothy Craig Carlson - Senior VP & CFO
We're capable of doing more than 40,000 tons next year. If all things go well, but right now, we're planning on 40,000 subs.
Operator
The next question comes from Duffy Fischer from Barclays.
Patrick Duffy Fischer - Director & Senior Chemical Analyst
Just to clarify that because I think you've said it a couple of different ways, that 40,000 tons increase 2021 to 2022, is that what you think you can produce more this year? Or that's what you think you can sell more this year? And if it's the first produce more, what will that do to optimal sales if the demand is there, if you run well, when you think about did stuff come out of inventory last year? Was there some sales in December that got pushed into January? What does that 40,000 number push forward into a sales volume number if all goes well?
John D. Romano - Co-CEO & Director
Yes. That's a great question. And I guess from the standpoint of -- we mentioned earlier in the call that our service levels aren't where they need to be. We do have a working capital built into the numbers in 2022. So will we sell all of that 40,000 tons that we produce, the objective would be -- our customers would love to have it, but we need to fill some of that supply chain. So I would expect a portion of that would actually go to replenish inventory so that we can improve our service levels. JF?
Jean-François Turgeon - Co-CEO & Director
No, that's absolutely right. And I think Duffy, Tim explained that sometime you have things outside of your control that could affect slightly more production out of all those 9 plants or slightly less. At the moment, we feel very confident about the 40,000 tons, but...
John D. Romano - Co-CEO & Director
In the range we provided.
Jean-François Turgeon - Co-CEO & Director
In the range. That's right.
Patrick Duffy Fischer - Director & Senior Chemical Analyst
Fair enough. And then with the mining projects you have underway, if you look out, let's say, 3 years from now, how much more and/or less would you have of iron ore byproducts and zircon byproducts to sell once these projects are done?
Jean-François Turgeon - Co-CEO & Director
Well, remember, I talked about Atlas-Campaspe being a new mine. And like any new mine in the first year of production, you're in the high-grade zone as opposed to an end of the life mine like Ginkgo and Snapper. So we expect that for -- when Atlas-Campaspe is in full operation, which would be 2023, we will get slightly more natural rutile and zircon than what we will get in 2022, and that would carry on to 2024.
And that's why we're starting to invest in some of our mine in South Africa so by 2024 and 2025, we could maintain the 85% vertical integration because obviously, we're growing our TiO2 production. So we need to grow our feedstock to be in line to maintain the cost advantage that this gives us. But we're very lucky with our mining asset because we have great reserve, and we also have very important resource that we could transfer -- well, convert into reserve as needed. And that's why knowing how the market is strong at the moment and how tight is the feedstock, we're preparing ourselves to be in a good position for the future.

The next question comes from Roger Spitz from Bank of America.
Roger Neil Spitz - Director & High Yield Research Analyst
I wonder if you can give us a sense of what 2023 CapEx looks like? Or maybe talk about are there any material CapEx additional amounts to be spent in 2023 for Atlas-Campaspe, or what is the Fairbreeze and Namakwa look like for 2023?
Timothy Craig Carlson - Senior VP & CFO
Roger, it's Tim. Atlas-Campaspe will go live this summer -- or summer. And as a result, there will be no spend next year. However, we will invest in our South African mines, as JF talked about of pulling those forward. So I would expect a similar capital number of $375 million to $400 million next year, with that ramping down a little bit when we finalize newTRON in 2023 into 2024.
Roger Neil Spitz - Director & High Yield Research Analyst
Perfect. And can you give -- you talked about significant new volume contracts. Can you tell us what percent of your total volumes here are under contract? I mean, how is it different from where you were in 2021 in terms of TiO2 pigment sold under contract?
John D. Romano - Co-CEO & Director
Yes, Roger. So what I could -- what I'll say is that we were able to secure long-term volume contracts, and that was in every region. And I would say we more so in Asia-Pacific, picked up a lot more contracts than we would have historically. We've never really disclosed a lot of detail about what percentage of our volume is under contract. But what I can say at this particular stage is that the volume contracts we have in place that are long-term multiyear agreements are now well above 50% of our volume, and it's going to allow us to make -- to confirm and hold our market share well beyond 2022.
Roger Neil Spitz - Director & High Yield Research Analyst
Got it. Meaning something well below 50% is sold on spot in 2020 June.
John D. Romano - Co-CEO & Director
I would say nothing is really on spot at this particular stage. There's different types of agreements that may not be as long-term. But it's a significant amount beyond 50% that's now multiyear and a lot of that volume got contracted in 2021.
Roger Neil Spitz - Director & High Yield Research Analyst
Got it. Short-term contracts. All right.
Operator
The next question is a follow-up from John McNulty from BMO Capital Markets.
John Patrick McNulty - Analyst
Yes. Just 2 of them. So the value stabilization contracts that you had in place historically, and that was kind of a program that you were pushing forward, I guess can you give us some clarity as to how much of your volume is committed to those, where the pricing will go up with collars around them or what have you versus what will be a little bit more fluid with whatever the market moves that, is there a way to think about that?
And then a second question would just be, it sounds like Jazan is heavily on track. I think when you originally gave a forecast for what the earnings power from 1 furnace and 2 furnaces would be, you had ore prices that were noticeably lower than where they are now. I guess can you give us an update as to how we should think about the economics of that on kind of a run rate basis when furnace 1 is up and when potentially furnace 2 gets up as well?
John D. Romano - Co-CEO & Director
John, I'll take the first one, and I'll let JF take the second one. So from the standpoint of our contracts and how they're broken down, again, we haven't provided a lot of detail around margin stability agreements. That's actually our MSA, not DSA. It's significantly less than we had on the long-term contracts that are volume-based. So when you think about the cadence and how our pricing has moved through the last 4 quarters, we expect to continue to see that movement actually in the first quarter of 2021 -- or 2022, we had some of those MSAs that actually reset in January, which actually was a benefit for us. But the majority of our volume contracts, when you think about that as a comparison to our MSAs, we have the ability to move price with the market. JF, do you want to touch on Jazan?
Jean-François Turgeon - Co-CEO & Director
Yes. I think John wants to be more on the financial of Jazan. So Tim, you want to...
Timothy Craig Carlson - Senior VP & CFO
Yes, I'd be happy to. John, just as a reminder, as one furnace operates at not full capacity, but normal capacity, 80%, 90%. For a full year, it's worth about $75 million of EBITDA for 1 furnace. Obviously, that assumes full operational for a year. And the time and ramp of the second furnace has not yet been fully finalized yet.
