Tim S. Nicholls
Senior Vice President and Chief Financial Officer at International Paper
Thank you Mark. Good morning everyone. Turning to our second quarter key financials on Slide 4. Operating earnings per share increased sequentially and also came in better than the outlook we provided last quarter, as we effectively optimized our system through commercial and operational initiatives.
Operating margins continued to be impacted by low volumes, but improved sequentially as lower outage expense and favorable input costs more than offset the impact from lower sales prices. In the second quarter, we generated $261 million in free cash flow. Recall that free cash flow from the first quarter was impacted by $193 million final settlement payment to the IRS related to our timber monetization, which allowed us to further derisk our balance sheet.
Moving to second quarter sequential earnings on Slide 5. Second quarter operating earnings per share was $0.59 as compared to $0.53 in the first quarter. Price and mix was lower by $0.29 per share due to index movements across our portfolio, lower export prices and unfavorable product mix in our Global Cellulose Fibers business as a result of lower absorbent pulp shipments. Volume was sequential -- was flat sequentially as improved demand in our North American Industrial Packaging business was offset by weaker demand in our Global Cellulose Fibers business. Volume in both businesses were impacted by customer inventory destocking. Operations and costs were also flat as our mills continue to run very well. Higher option costs in our Industrial Packaging business, primarily due to economic downtime was offset by lower option cost in our Global Cellulose Fibers business. Maintenance outages were lower by $88 million or $0.19 per share in the second quarter and we saw significant relief from input costs, which were $83 million or $0.18 per share lower, primarily driven by lower energy wood and distribution costs.
Turning to the segments, and starting with Industrial Packaging on Slide 6. Price and mix was lower due to index movements and lower export prices. This was partially offset by benefits from commercial initiatives focused on margin improvement. Sequentially, volume was higher despite one less shipping day as demand continue to improve throughout the quarter from the large trough. Our US box shipments were down 8.3% year-over-year in the second quarter as demand for packaging and continued to be impacted by ongoing inventory destocking by our customers. However, June was down 5.9% year-over-year as the quarter improved. More demand environment impacted operations and costs in the quarter, as we align our production with our customer demand, while also optimizing our inventories and taking fewer planned maintenance outages. These actions resulted in approximately 622,000 tons of economic downtime across the system, which accounted for approximately two-thirds of the option [Phonetic] cost variance. The remainder was primarily due to timing of spending for materials and services. Overall, our mill system ran very well. Planned maintenance outages for lower by $54 million sequentially, partially reflecting deferral or some outages in the second half of the year as we continue to optimize our outages. Significantly lower input costs, improved earnings by $66 million in the quarter. We benefited from lower energy wood and distribution costs, some of which was due to the relentless efforts by our business teams to crawl back high marginal costs while optimizing our systems in the current demand environment. Give you an example of this, our mill and fiber and procurement teams have made tremendous progress reducing fiber costs by optimizing mix and shedding our highest cost supplier of fiber to the mills. Our teams across the mill and box plants also are driving significant reductions in distribution cost by doing things like reducing highest cost freight carriers, renegotiating contract rates, increasing weights per load, reducing miles per load, and shedding [Phonetic] warehouse and to merge the expense.
Turning to Slide 7, I'll share some perspective regarding how inventory destocking is progressing for our customers. Based on their feedback and our own analysis, we believe inventory destocking across the supply-chain has accounted for a large portion of overall demand declines this year. It is also lasting longer than initial expectations due to the limited visibility across the entire supply chain of excess inventories built-up during the pandemic. Feedback from some of our larger customers suggests that approximately 75% of them entered the third quarter at or below inventory levels -- target inventory levels. Good news is that given feedback from our customers and looking at the data, we expect this destocking trend to be completed in the third quarter.
On Slide 8, some additional data supports our current view. We believe the majority of retailer inventory destocking was completed in the first quarter. However, manufacturers were still reducing inventories through the second quarter as a result of lower demand levels, improved supply chain velocity and focus on working capital and even higher interest rates. Despite the current environment. Corrugated Packaging plays a critical role in bringing essential products to consumers. IP is well-positioned to grow with our customers over the long-term due to our [Indecipherable] portfolio of products and services and our strategic relationships with a large number of national and local customers across a broad range of attractive and new segments.
Turning to Global Cellulose Fibers on Slide 9. Taking a look at the second quarter performance, price and mix was lower due to price index movement, and higher level of commodity grades in the quarter in response to weaker fluff pulp shipments. As a reminder, approximately 85% of the products in this business are exported as International Paper serves major global and regional customers around the world. As we entered the year, fluff pulp volumes came under pressure. First, consumer demand for absorbent hygiene products was lower driven by inflationary pressures and second, there was significant inventory destocking across the long supply chains. This destocking trend continued in the second quarter as supply chains became more efficient and reliable. As a result, customers were able to work down safety stocks that were built-up in response to the supply-chain disruptions during the pandemic. This resulted in approximately 143,000 tons of economic downtime across the system as we aligned our production with customer demand. The combined impact of lower volumes and higher mix of commodity grades continue to negatively impact business earnings. Looking-forward, based on feedback from our customers and the order bookings, majority of destocking should be completed in the third quarter and we believe fluff demand will continue to grow over the long-term. This is due to the essential role absorbent personal products play in meeting customer needs.
Coming back to the second quarter, operations and costs improved sequentially as we [Indecipherable] for more distribution costs and our business teams remain focused on driving down the high marginal costs going-forward. Sequentially, option costs were also favorably impacted by seasonally lower energy consumption and higher residual energy sales. Planned maintenance outages were lower by $34 million sequentially. And input cost were lower by $17 million due to low-energy and chemical costs.
Turning to Slide 10, I'll take a moment to update you on our capital allocation actions. We have a strong balance sheet, which is core to our capital allocation framework. Looking ahead, we have limited medium term debt maturities and our pension plan remains fully funded. Returning cash to shareowners is a meaningful part of our capital allocation framework. In the second quarter, we returned $200 million to shareowners. Going forward, we are committed to returning cash by maintaining our dividends. Investment excellence is essential to growing earnings and cash generation. We invested $267 million in our businesses in the second quarter, which includes funding for cost reduction projects with attractive returns and for strategic projects to build out capabilities and our box system. Going forward, we plan to make additional investments across our box system to support long-term profitable growth. We will remain disciplined and selective when assessing M&A opportunities.
On Slide 11, we'll take a look at the third quarter outlook. I'll start with Industrial Packaging. We expect price and mix to decrease earnings by $95 million as a result of prior index movement in North America and lower average export prices based on declines to date. Volume is expected to increase earnings by $5 million due to improving demand in daily shipments in North America offsetting one less shipping day. Operations and costs are expected to increase earnings by $95 million. More than half is due to lower-cost of company paid benefits and our cost management initiatives. The balance is primarily due to lower unabsorbed fixed cost. Maintenance outage expense is expected to increase earnings by $28 million. And lastly, rising input costs are expected to decrease earnings by $15 million from higher average energy cost.
Switching to Global Cellulose Fibers. We expect price and mix to decrease earnings by $40 million as a result of prior Index movements and declines in spot pricing to date. Volume is expected to increase earnings by $10 million as demand improves from lower inventory destocking. Operations and costs are expected to be stable relative to the second quarter. Maintenance outage expense is expected to increase earnings by $12 million. And lastly, declining input costs are expected to increase earnings by $10 million mostly due to lower fiber and chemical costs.
Slide 12, we'll take a look at the full-year outlook. As we entered the year, we recognize the macroeconomic uncertainties ahead of us and that our businesses were not immune to these risk. These macro trends have shifted resulting and weaker-than-expected demand for our products and price reductions across our portfolio through the second quarter including prior index changes, that will be implemented over the remainder of the year, I would also remind you that we -- that when we provide an outlook it includes only the impact from published price changes to date. We are now projecting full-year 2023 EBITDA for the company to be in the range of $2.1 billion to $2.3 billion. Despite the market headwinds, we are taking actions across the company to optimize our system by reducing high marginal cost and driving additional, commercial and cost benefits from our Building a Better IP initiatives. Mark will share more about these opportunities in the next few slides. Free cash flow is expected to be between $500 million and $600 million, including the one-time tax payment of $193 million in the first quarter related to our timber monetization settlement. For 2023, we are targeting capex of $1.1 billion to $1.2 billion, with increased investments in our US box system.
And with that, I'll turn it back over to Mark.
