Scott Tozier
Executive Vice President and Chief Financial Officer at Albemarle
Thanks, Kent, and good morning, everyone. I'll begin on slide five. During the quarter, we generated net sales of approximately $1.5 billion, a year-over-year increase of 91%. This is due primarily to increased momentum in our pricing efforts as well as higher volumes driven by strong demand across our diverse end markets, especially for our Lithium and Bromine businesses. We saw volumes and pricing grow in all three of our businesses. For the second quarter, net income attributable to Albemarle was $407 million compared to $425 million in the prior year. As a reminder, the year ago quarterly results included a onetime benefit of $332 million related to the sale of Fine Chemistry Services. EPS for the second quarter was $3.46, a year-over-year improvement of 300%, excluding the onetime benefit of the FCS sale. This overall performance was driven by strong net sales and margin improvement, partially offset by the ongoing inflationary pressures we are feeling across all three businesses. Turning to slide six. Second quarter adjusted EBITDA was $610 million, up 214% year-over-year. The primary driver of the strong growth was higher lithium EBITDA.
Lithium was up nearly $400 million compared to the prior year driven by momentum in our contracting efforts and overall higher market prices. That's an increase of 350%. In fact, lithium's second quarter EBITDA was greater than the EBITDA it generated in the full year of 2021. Bromine was also favorable year-over-year, up nearly 50%, reflecting higher pricing driven by tight market conditions and an uptick in volumes, partially offset by raw material and freight inflation. Catalyst was negative in the quarter as higher sales volumes and pricing were more than offset by cost pressures, particularly for natural gas in Europe and raw materials. And finally, we also experienced an overall FX headwind of $14 million for the total company. Moving to slide seven. We are further increasing our 2022 outlook from our last announcement in late May primarily to reflect the expected continued strength in execution in our Lithium business and further improvements in Bromine. We now expect 2022 total company net sales to be in the range of $7.1 billion to $7.5 billion, up about 115% to 125% versus last year. Adjusted EBITDA is expected to be between $3.2 billion and $3.5 billion, reflecting a year-over-year improvement of up to 300%.
This implies EBITDA margins are expected to improve significantly to a range of 45% to 47% for the total company. Together, this translates to updated 2022 adjusted EPS guidance in the range of $19.25 to $22.25. That is about 5 times more than 2021. Additionally, we are increasing our net cash from operations guidance to a range of $1.4 billion to $1.7 billion driven by our updated sales and margin expectations. We are maintaining guidance for capital expenditures of $1.3 billion to $1.5 billion as we drive our lithium investments forward to meet increased customer demand. Together, the midpoint of our guidance implies approximately $150 million in positive free cash flow for the full year. And further, if you assume our realized pricing remains relatively flat next year, we expect to continue to generate positive free cash flow in 2023, even with continued growth investments. Security of supply remains the number one priority for our customers.
And we are continuing to partner and work closely with them. We are pushing hard to meet those accelerating customer growth requirements. Regarding the quarterly progression of sales and EBITDA. On our last call, we indicated that we expect results to be relatively evenly split among quarters. Given the underlying strength across our portfolio and continued momentum in our contracting efforts, we now expect second half adjusted EBITDA to be roughly 120% higher relative to the first half. Turning to the next slide for more detail on our outlook by segment. Our Lithium business' full year 2022 EBITDA is expected to be up more than 500% year-over-year, up from the previous outlook for growth of approximately 300%. The improved outlook reflects renegotiations of pricing on legacy fixed-price contracts and continued strong market pricing flowing through our indexed referenced variable price contracts. We now expect our average realized selling price to be up more than 225% to 250% year-over-year.
This is the result of our successful efforts to renegotiate legacy contracts and implement more index referenced variable price contracts as well as a significant increase in index prices. From the beginning of the year to today, indices are up 60% to 130%. And note that our outlook assumes Albemarle's expected Q3 realized selling price remains constant into the fourth quarter. There's no change to our lithium volume outlook for the year. We continue to expect year-over-year volume growth in the range of 20% to 30% as we bring on new conversion assets plus some additional tolling. There is potential upside to our outlook if market prices remain near current levels or with additional contract renegotiations or additional tolling volumes. And conversely, there is potential downside with material declines in market pricing or volume shortfalls. For Bromine, we are also raising our full year 2022 EBITDA expectations with year-over-year improvement in the range of 25% to 30% compared to the prior outlook of 15% to 20%. This revised guidance reflects continued strong demand and pricing from end markets such as fire safety solutions and oilfield services plus other macro trends such as digitalization and electrification. We expect higher volumes of 5% to 10% following our successful execution of growth projects last year.
For Catalysts, full year 2022 EBITDA is expected to be down 25% to 65% year-over-year. This is below our prior outlook due to significant cost pressures primarily related to natural gas in Europe, certain raw materials as well as freight, partially offset by higher sales volumes and pricing. The large outlook range for Catalysts reflects increased volatility and a lack of visibility particularly related to the war in Ukraine. Given the extraordinary circumstances and the resulting changes in oil and gas markets, the business continues to aggressively seek cost pass-throughs particularly for higher natural gas costs. The strategic review of the Catalysts business is ongoing, but it is taking longer than we anticipated. As soon as we have any news, we will provide an update. Turning to slide nine for an update on our lithium pricing and contracts. This slide reflects the expected split of our 2022 lithium revenues. Battery grade revenues are now expected to make up approximately 85% compared to 70% to 80% in our prior guidance due to successful contract negotiations and higher market indices. Of the total battery grade revenues, 15% is expected to be from short-term spot purchase orders. 65% is expected to be from index reference variable price contracts. Pricing on these contracts generally reset with a 3-month lag.
And a number of these contracts do have floors and ceilings in place. The remaining 20% comes from legacy fixed contracts with price reopeners, normally every six or 12 months. And since we last updated the outlook in late May, we have successfully repriced a portion of these contracts to better reflect the current market price environment. This segmented approach to contracting gives more flexibility for our customers while allowing Albermarle to preserve upside and ensure returns on our growth investments. Our operations and project teams are also delivering volumetric growth. slide 10 shows the expected lithium sales volumes, including technical-grade spodumene and tolling sales. In 2022, we expect volumes to improve 20% to 30% year-over-year. This growth is largely driven by our expansions at La Negra and Kemerton, the acquisition of Qinzhou as well as some additional tolling volumes.
Looking forward, we expect volumes to grow approximately 20% per year from 2022 to 2025 driven primarily by the ramp-up of new conversion assets. We see room for further upside from additional conversion assets such as our greenfield in Meishan or additional tolling volumes. Turning to slide 11. Our strong net cash from operations and solid balance sheet give us ample financial flexibility to execute our growth strategy. Our balance sheet is in great shape with $931 million of cash and available liquidity of $2.6 billion. Current net debt to adjusted EBITDA is approximately 1.7 times. With rising EBITDA from higher pricing and volumes, we expect leverage to trend lower in the near term. This gives us plenty of capacity to accelerate our growth investments or value-creating M&A.
During the second quarter, we extended our debt maturity profile through a public offering of senior notes. Proceeds totaled approximately $1.7 billion, a portion of which was used to redeem senior notes maturing in 2024. 92% of our debt position is at a fixed rate, which buffers us against the impacts of the rising interest rate environment. Before I turn the call back over to Kent, I wanted to briefly review our capital allocation priorities and our ability to adapt to market changes while building durable capacities to support growth. Our capital allocation priorities are unchanged. We remain committed to strategically grow our lithium and bromine capacity in a disciplined manner. Capacity growth will also be supported inorganically by continuously assessing our portfolio and pursuing bolt-on acquisitions at attractive returns to strengthen our top-tier resource base.
A perfect example of this strategy is the $200 million Qinzhou acquisition that is expected to close in the second half of the year. Maintaining financial flexibility and shareholder returns are also key capital allocation priorities. We remain committed to maintaining an investment-grade rating and a strong balance sheet to provide significant optionality to fund future growth. Finally, we also plan to continue to support our dividend. We are laser-focused on the durability of our business. The management team and the Board regularly review our capital allocation priorities and have identified levers we can pull to quickly adapt to changing market conditions if needed. These include slowing non-growth capex, reducing discretionary spending and hiring, shifting production volumes to highest demand markets and accelerating partnering and tolling arrangements to support cash generation. Additionally, a downturn may allow us to take advantage of lower priced acquisitions, capitalizing on the strength of our balance sheet. In summary, we believe Albemarle's ability to maintain a focus on growth through all market conditions is strong, thanks to our operating model that Kent is going to discuss next.
