Good morning, everyone, and thank you for joining Greif's fiscal fourth quarter 2025 earnings conference call. Today, our CEO, Ole Rosgaard, will provide a strategy and market update, followed by our CFO, Larry Hilsheimer, with a review of our financial results and 2026 guidance. Please turn to slide two. In accordance with regulation fair disclosure, please ask questions regarding topics you consider important because we are prohibited from discussing material non-public information with you on an individual basis.
During today's call, we will make forward-looking statements involving plans, expectations, and beliefs related to future events. Actual results could differ materially from those discussed. Additionally, we will be referencing certain non-GAAP financial measures and the reconciliation to the most directly comparable GAAP metrics that can be found in the appendix of today's presentation. Two important reporting clarifications for this quarter. First, our container board business was sold on August 31.
As such, that business is presented as discontinued operations for its one-month contribution to the quarter. Unless otherwise noted, all financial results and commentary discussed today will relate to continuing operations only. Second, due to our fiscal year-end change, Q4 reflects a two-month reporting period, August and September. For consistency, all prior year comparatives in today's presentation are also shown on a two-month basis for August and September. I'll now hand the call over to Ole on slide three.
Thanks, Bill, and thank you all for listening in today and for your interest in Greif. With the short 2025 fiscal year due to our fiscal year change, the two-month fourth quarter, the sale of our containerboard business this quarter, and the ongoing cost optimization program, we know there's a significant amount of change and noise for this quarter. This shows up in our tax results, which Larry will be discussing in a moment. Thank you for bearing with us. We are excited for the long-term earnings growth and value creation.
Our strategy is unlocking. We closed fiscal 2025 as a more focused, more agile, and more strategically aligned company than at any time in our history. Our transformation is accelerating, and the results are beginning to show. On October 1, we finalized the sale of our land management business, generating $462 million in proceeds.
Those funds were used immediately to reduce debt, and our pro forma leverage ratio is now under 1.0 times. We have entered fiscal 2026 with a meaningfully stronger balance sheet, with enhanced capital efficiency built for resilience. Together with the divestiture of our containerboard business in the fourth quarter, we have reshaped Greif's portfolio to concentrate our efforts where we have the greatest opportunity to grow EBITDA, expand margins, generate cash, reduce cyclability, and deliver durable returns for our shareholders.
We are pleased to report our latest Net Promoter Score survey result of 72. An improvement of 3 points from last year and further extending our world-class customer service performance. That improvement is a direct reflection of the trust our customers place in us and our ability to deliver for them.
The best companies build stronger relationships when things are difficult, and our NPS reflects our conviction that we will capture significant value when demand returns. As Larry will touch on in a moment, our full year 2026 guidance, despite being low-end, reflects continued earnings growth and a free cash flow conversion rate of 50%. Demonstrating our progress towards the long-term objectives laid out at Investor Day in December. We are proud of how we ended fiscal 2025, but even more energized by what lies ahead.
Our Build to Last strategy is firmly embedded in our organization. We are shaping and sharpening our portfolio, strengthening our balance sheet, and investing for sustainable growth. Please turn to slide four. Our commitment to value creation shows in how we manage cost. In fiscal 2025, we achieved $50 million in run rate savings from our cost optimization program.
More than double our stated full year 2025 commitments. To date, we have achieved approximately $15 million in savings related to network design and operating efficiency. This is not limited to strategic footprint actions. It also includes deploying AI solutions to reduce scrap and improve OEE. Strategic planning actions to minimize freight and maximize on-time deliveries, and structural improvements to our global procurement strategy. The remaining run rate savings are related to SG&A.
Our updated business model has enabled much more efficient decision-making. It has also led to difficult but necessary decisions to eliminate areas of redundant cost in the updated model. As of quarter end, we have eliminated approximately 8% of professional roles within the company, or 190 positions.
These changes have been carefully considered over this past year and were acted on in Q4 in a manner which allowed us to communicate to impacted colleagues our heartfelt appreciation for their contributions to Greif. These actions drove the significant acceleration beyond our previous full year 2025 commitments. Due to our progress to date, we are raising our anticipated fiscal 2026 cumulative cost-saving run rate commitment from $50 million-$60 million to $80 million-$90 million.
We will also expand our anticipated full year 2027 cumulative run rate commitment from $100 million to $120 million. Our cost optimization program has continued to evolve since the start of the year. What began as a top-down initiative is now being fueled from the ground up. Across the organization, our colleagues are embracing the challenge, identifying new opportunities, driving local action, and creating meaningful change.
This work is making Greif a more focused and agile organization, better positioned to capture value as demand returns. Importantly, this isn't just about taking cost out. It's about building an agile next-generation Greif. The Greif business system enables repeatable excellence across more than 250 sites in 40 countries, allowing us to do more with fewer resources.
We are removing unnecessary layers to empower local leaders and speed up decision-making, and we are embedding a mindset of efficiency, responsiveness, and value creation across every function and facility. This isn't a one-time initiative. It's a structural shift in how we operate, compete, and grow. Excuse me. Please turn to slide five. A significant finding from our cost optimization program, which is now realizable as the divestment of container board, are the clear and meaningful synergies in operating adhesives and recycled fiber as part of sustainable fiber solutions.
Thank you, everyone. Or thank you, Ole. Hello, everyone. As a reminder, our results are presented excluding the container board divestment, except for free cash flow, which compares total operations to the prior year. Additionally, due to our fiscal year change, Q4 reflects a two-month reporting period, August and September. For consistency, all prior year comparatives in today's presentation are also shown on a two-month basis. Adjusted EBITDA for the quarter was $99 million, which was 7.4% above the prior year.
EBITDA margins also expanded year over year by 140 basis points due to better price cost across all segments and the building momentum of our cost optimization. Adjusted free cash flow also improved year over year by over 24.3% due to the increase in EBITDA and our team's strong working capital management to close the year.
As noted in our presentation, SG&A includes $28 million of operating costs specifically related to the container board divestment, which are excluded from EBITDA. Excluding these costs, SG&A was slightly above the prior year quarter due primarily to the two-month quarter, including certain annual or quarterly costs which were occurred over a shorter year. Adjusted EPS for the quarter was $0.01 relative to $0.59 in the prior year quarter.
Our Q4 tax expense was impacted by non-recurring items affecting pre-tax income and the residual nature of continuing operations after removing discontinued operations. Tax expense also includes various taxes either not based on income or not directly correlated to current period income, the impact of which is magnified due to the lower income reported in this two-month period. Finally, the tax expense was also influenced by the mix of earnings across the jurisdictions in which we do business.
Please turn to slide eight. In polymers, growth was led by small containers, consistent with our long-term strategic focus on less cyclical, margin accretive end markets. Sales and gross profit were both up year over year, with margin tailwinds from mixed pricing and operational discipline. In metals, results reflected volume softness in industrial end markets. Sales and volume declined, but we continued to generate healthy cash flow and remained focused on cost reduction and enhancing agility to react as demand recovered. In fiber, the decline in sales was tied to volume, with URB mill downtime late in the quarter.
Despite that, gross profit dollars and margin improved year over year due to continued benefits from price cost and tight cost management. Integrated solution sales and gross profit dollars declined year over year primarily due to lower published OCC prices in our recycled fiber group.
Volumes in recycled fiber and closures were both solid, and the product's MIC impact of closures led to higher gross margins year over year. Please turn to slide nine. Given the continued demand environment we are operating in, we believe it is prudent to present low-end guidance to begin fiscal 2026. Our low-end scenario assumes flat to low single-digit volume declines in metals and fiber. It also assumes low single-digit volume improvement in polymers and closures from growth in our target end markets.
The net impact of these volumes assumptions is flat volume-related EBITDA performance to prior year. Transportation and manufacturing costs were also assumed flat, representing cost savings on our cost optimization, offsetting normal inflationary cost increases. The two major positive drivers in our grid are SG&A and price cost, both of which reflect the accelerated progress on our cost optimization program.
SG&A of $45 million reflects $39 million of incremental cost optimization, of which $17 million is within the fiscal year 2025 run rate and $19 million is within the fiscal 2026 run rate, both of which are expected to benefit fiscal 2026. The additional $9 million represents lower variable costs, including incentives. Price cost reflects $12 million of incremental cost optimization.
This is primarily in the form of sourcing benefits in polymers and closures, while metals cost base is assumed flat. Price cost also reflects an $18 million incremental benefit of URB pricing recognized in fiscal 2025 and lower expected OCC cost. Lastly, to round out our grid, a $10 million EBITDA headwind from the lack of land management and a benefit of $7 million. Positive FX driven by the weakening of the US dollar. Our free cash flow.
Low-end guidance is $315 million, a 50% conversion ratio demonstrating our progress towards our long-term objectives. We expect to spend approximately $155 million on CapEx this year. Our lower cash interest cost reflects our strong balance sheet, and our other cash use includes approximately $40 million of cash restructuring related to the cost optimization, as well as pension cost.
Working capital assumes a source of $50 million, driven by both low-end volume assumptions and optimization gains. Please turn to slide 10. With our pro forma leverage below 1.0 and strong cash flow guidance of $315 million, we anticipate minimal cash needs for debt service costs in the year ahead. Similarly, after divesting our most capital-intensive business earlier this year, our maintenance CapEx needs are approximately $25 million lower.
Thank you again for your interest in Greif. We acknowledge that the last 11 months have been bumpy given all the change occurring, and that showed up in this quarter in our tax results. As always, my commitment to you is transparency and candor. We are proud of how we finished fiscal 2025: more focused, more efficient, and more aligned with our long-term strategy.
We are also excited for a cleaner outlook in full year 2026 and will continue to communicate progress on our strategy with as much clarity as possible. The divestments of container board and land management have meaningfully reshaped our business. We are now positioned with a sharper portfolio, lower capital intensity, and stronger financial flexibility than ever before. Our cost optimization program is ahead of plan and with an expanded $120 million commitment by the end of 2027.
We are building a stronger business, one that creates value in any environment and delivers accelerating performance as volumes return. Thank you for your continued support. Operator, please open the lines for questions.
