Thank you, Andy. Good morning, everyone. I'm on Slide 13 now, where I'll provide the details around the second quarter as we walk through the sequential earnings bridge. Second quarter adjusted operating earnings per share was $0.55 as compared to $0.17 in the first quarter. Recall that the first quarter included a $0.10 per share drag related to the January freeze and the Ixtac box plant fire. Price and mix was higher by $0.23 per share, driven by the flow-through of prior price index movements as well as margin and mix benefits from successfully executing our box go-to-market strategy and our GCF optimization strategy.
Volume was favorable by $0.06 per share. Although we continue to see favorable demand trends deploying our commercial, strategies across the portfolio continues to impact volumes in the near term as expected as we transition based on our strategy. Operations and cost was unfavorable by $0.01 per share sequentially. This is largely from the impact of inflation, higher S&A and spending to improve reliability in our packaging business, partially offset by mill efficiencies following the pulp machine closure at our Riegelwood mill.
Maintenance outages were lower by $16 million or $0.03 per share in the second quarter and input costs were overall flat sequentially with decreased costs for energy and freight, offsetting increased costs for OCC and chemicals. And finally, corporate items favorably impacted earnings by $0.07 per share sequentially due to a lower effective tax rate.
Turning to the segments and starting with Industrial Packaging second quarter results on Slide 14. Price and mix was higher due to the realization of approximately $45 million of benefits from prior index movement. Additionally, benefits from our box go-to-market strategy contributed approximately $25 million of earnings benefit from improved margins and mix. and higher export and mix contributed approximately $21 million. Volume was higher by $27 million sequentially given the stable to improving demand trends we are seeing. However, as expected, our Box Go-to-Market strategy is about making choices that impacts our volume in the near term. Although we expect to trail the industry for the next few quarters, we believe our Box Go-to-Market strategy will allow us to improve our margins and mix over the long term.
Operations and costs was $43 million, unfavorable sequentially due to the impacts of inflation, higher S&A and spending to improve reliability. Planned maintenance outages were higher by $3 million sequentially and input costs were $3 million favorable, primarily due to lower energy more than offsetting higher OCC costs.
Moving to Slide 15. I'll cover the Global Cellulose Fiber second quarter. Price and mix was sequentially higher by $22 million due to the price index movement and GCF optimization strategy, driving benefits from higher absorbent pulp mix and the reduction in commodity grades. Volume sequentially was relatively flat overall as improved demand for absorbent pulp was offset by lower sales of commodity grades as we continue to focus on strategically aligning our business with the most attractive customers and segments.
Operations in cost was favorably -- was favorable sequentially by $36 million. A large portion of this benefit is related to the pulp machine closure at our mill in Riegelwood, North Carolina. Planned maintenance outages were lower in the second quarter by $19 million as planned. And finally, input costs were higher by $1 million with lower energy costs, not quite offsetting higher chemical and wood costs.
Turning to Slide 16. I'm going to provide our outlook for the third quarter. As Andy said earlier, we expect lower sequential earnings due to volume decline and higher costs, offsetting benefits from the prior price index increases. For our Industrial Packaging segment, earnings are expected to be down sequentially in the third quarter by approximately $160 million. and earnings will be relatively flat for global cellulose fibers.
Now let me give you the breakdown. I'll start with Industrial Packaging. We expect price and mix to improve earnings by approximately $60 million sequentially. This is the result of prior index movement in North America as well as higher export prices to date. I would also note that approximately $13 million of the expected improvement is related to our Box go-to-market strategy. Volume is expected to decrease earnings by approximately $65 million due to one less shipping day and seasonally lower demand.
We expect operations and costs to decrease earnings by approximately $80 million. This includes higher reliability spending, labor and benefits costs during the summer months and higher unabsorbed fixed costs. Higher maintenance outage expense is expected to decrease earnings by approximately $44 million. And lastly, higher input costs are expected to decrease earnings by approximately $30 million, primarily due to higher energy costs.
Switching to Global Cellulose Fibers, we expect price and mix to increase earnings by approximately $10 million as a result of prior index movement. Volume is expected to decrease earnings in the third quarter by approximately $5 million due to seasonally lower demand. We expect operations and costs to decrease earnings by approximately $25 million, largely due to higher distribution costs and timing of spend as well as higher unabsorbed fixed costs. Lower maintenance outage expense is expected to increase earnings in the third quarter by approximately $25 million. And lastly, input costs are expected to be stable.
With that, I'll turn it back over to Andy.
