In January 2024, when Graeme Pitkethly stepped down after nearly a decade as Unilever's CFO, he left behind a number that should haunt every finance chief: negative €3.2 billion.

Most finance executives can recite the cash conversion cycle in their sleep: CCC = DSO + DIO, DPO. The mechanics are taught in every MBA program.

Consider three reasons working capitalworking capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → deserves disproportionate CFO attention in 2026:
1. It's the cheapest capital you'll ever raise. Releasing $100 million from inventory is not equivalent to raising $100 million in debt, it's substantially better. There are no covenants, no rating agency conversations, no Pillar Two tax implications on interest deductibility, and no dilution.

2. It compounds invisibly. A 5-day reduction in DSO at a company with $10 billion in revenue releases roughly $137 million in cash, *permanently*. That capital, redeployed at the company's WACC (say 9%), generates $12 million in annual value creation in perpetuity. Yet because the gain appears as a one-time movement in the cash flow statement, it rarely gets the strategic credit it deserves.
3. Post-COVID supply chain reconfiguration changed the math. The just-in-time orthodoxy of 2015 is dead. Companies that ran lean inventories through 2019 lost billions in 2021-2022 stockouts. The new playbook, championed by CFOs like Apple's Luca Maestri and now Kevan Parekh, is *strategic inventory positioningpositioningThe mental space you want your brand to occupy in your target customer's mind relative to alternatives.View full definition →*: holding more of the right SKUs in the right geographies, while ruthlessly purging the wrong ones.

When Graeme Pitkethly took over as CFO in 2015, Unilever's net working capitalnet working capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → ran at roughly +3% of sales, meaning the company had over €1.7 billion tied up in operations. By the end of 2022, that figure had crossed into negative territory, eventually reaching , 5.3% of sales. The transformation released over €5 billion in cumulative cash, which Unilever redeployed into the €50 billion divestiture-and-acquisition program (including the Horlicks acquisition and the spreads divestiture to KKR) and a sustained buyback program.
The mechanics were not glamorous. They were three disciplined moves:
Unilever extended its standard payment terms to 75-90 days for most suppliers, controversial, and roundly criticized in the UK press. But the company paired this with a supply chain finance (SCF) program through banks like Citi and Santander, allowing suppliers to discount Unilever-approved invoices at near-Unilever borrowing rates (then around 1-2%) rather than their own SME rates of 6-10%.
The result: suppliers received cash *faster* than under the old 45-day terms, while Unilever extended its DPO by ~25 days. This is the textbook example of using a buyer's superior credit rating as a working capitalworking capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → weapon, and it's now coming under regulatory scrutiny under the EU's Late Payment Regulation and IFRS disclosures requiring SCF programs to be reported separately (effective for 2024 fiscal years onward). CFOs deploying SCF in 2026 must now disclose program size, terms, and bank exposures, a transparency shift that has caused several US issuers to scale back aggressive SCF use.
Unilever discovered that its global DSO of 38 days masked enormous variation: large modern-trade customers (Tesco, Walmart, Carrefour) paid in 25-30 days, but traditional-trade and emerging market distributors averaged 55-70 days. Rather than applying uniform pressure, the team built a risk-and-relationship matrix and offered factoring/receivables financing only to the long-tail customers, using the savings from improved cash flow to fund dynamic discounting for fast-paying customers.
The least sexy but largest contributor. Between 2017 and 2020, Unilever eliminated nearly 30% of its SKUs, including some legacy brands with revenue but negative working capitalworking capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → contribution.

Theory is useful, but execution wins.

Pull the last eight quarters of DSO, DIO, and DPO for your company and your five closest sector competitors. Don't use trailing twelve months, use quarterly data, because seasonality reveals operational discipline (or its absence). The relevant peer set is sector-specific:
If your CCC is more than 15 days worse than the sector median, you have a 9-figure cash opportunity. Period.
For each component (DSO, DIO, DPO), decompose the gap to peer median into:
This decomposition matters because each requires a different response. A policy gap means renegotiating contracts. An execution gap means fixing collections processes, dunning workflows, or treasury operations. A mix gap may require strategic portfolio changes.

1. Build the NWC Bridge for the last eight quarters. Decompose change into volume, operational, and mix effects. If your team can't produce this in two weeks, you have a data infrastructure problem that's blinding you to a 9-figure opportunity.
2. Benchmark against sector peers, not your own history. Improving from terrible to mediocre is not a victory. Use the median and top quartile of your sector as the goalposts. Aim to close half the gap to top quartile within 24 months.
