Thanks, Andres, and good morning, everyone. O-I reported first quarter earnings of $0.45 per share. Consistent with our expectations, results were down from historically high earnings of $1.29 per share last year. As illustrated, earnings primarily reflected a decline in segment operating profit, while slightly higher nonoperating expense was mostly offset by some favorable FX. Additional details on nonoperating items are included in the slide.
Let's turn to Page 6 and discuss recent performance across our 2 segments. The Americas posted segment operating profit of $102 million, which was down from $176 million last year. Net price was a slight headwind and sales volume was down 15%. Elevated operating costs reflected significant temporary production curtailment to balance supply with demand, which was partially offset by favorable margin expansion initiative benefits. In Europe, segment operating profit totaled $133 million, down from $222 million last year.
Like the Americas, net price was a modest headwind and sales volumes were down 10%. Higher operating costs reflected the impact of elevated temporary production curtailments, lower JV performance and prior year energy credits that did not repeat. These headwinds were partially offset by benefits from our margin expansion initiative program.
Let's turn to Page 7 to discuss our updated 2024 business outlook. As noted on the left, we have adjusted our full year earnings guidance for a few factors.
Net price is stable, yet we have reduced our sales growth expectations, reflecting a longer destocking process and a more gradual improvement in consumer consumption patterns than originally anticipated. Given softer demand, we intend to take incremental production curtailments to ensure inventories remain in check. Importantly, we are accelerating our curtailment activity in the second quarter following the softer start of the year.
To help mitigate slower sales growth, we have increased our full year initiative benefit target to at least $175 million. Finally, our outlook has been impacted by unfavorable FX trends, higher interest rates, given the change in the forward curve and a higher tax rate. As a result, we now expect adjusted earnings should approximate $1.50 to $2 per share compared to our prior outlook of $2.25 to $2.55 per share, and we have updated our view of quarterly earnings allocation.
Free cash flow should range between $100 million to $150 million, reflecting lower earnings, partially offset by other favorable cash levers, including moderately lower CapEx. We intend to maintain a healthy balance sheet position and expect to end the year with leverage both in the low 3s, which will naturally decrease as volumes and earnings recover.
As Andres discussed, we believe current market conditions are temporary. While it will likely take longer than originally anticipated, earnings should rebound when sales and production volumes substantially returned to pre-pandemic levels. Now I'll turn it back to Andres, who will provide an update on our key strategic objectives on Page 8.
