Out-of-Stocks During Sporting Events: The Hidden Revenue Leak

Out-of-stocks are one of the most visible execution issues in retail and also one of the most underestimated.

In most trading weeks, they are already a challenge but during major sporting events like the World Cup, they become something else entirely.

A concentrated, time-sensitive revenue risk.

When Demand Spikes, Availability Becomes Everything

From a commercial perspective, this will feel familiar.

You plan for demand:

  • Forecasts are adjusted
  • Stock is allocated
  • Promotions are aligned
  • Displays are scheduled

The expectation is clear: capture increased demand and drive incremental sales and during events like the World Cup, that demand doesn’t just increase.

It compresses.

  • Shoppers buy closer to key moments
  • Baskets get bigger
  • Categories spike in short windows

When everything is available, these moments can drive significant category growth but when products aren’t on shelf, the impact is immediate.

The Real Cost of Out-of-Stocks

Out-of-stocks are often measured as a percentage. Typically, brands lose 1–3% of revenue weekly due to availability issues.

During major events, that loss doesn’t spread evenly, it concentrates. A missed restock an hour before kick-off can create a huge marginal dip and once that moment passes, it can’t be recovered.

The sale doesn’t get delayed, it goes to a competitor and in many cases, that switch doesn’t stop at a single purchase.

When a shopper can’t find their preferred brand or format, they choose an alternative. If that alternative meets their expectations, it can start to shift future purchase behaviour.

What begins as a short-term availability issue can quickly become a longer-term share and loyalty challenge.

Why Out-of-Stocks Increase During Major Events

During high-pressure retail moments, several factors combine:

  • Increased demand volatility
  • Higher store traffic
  • Faster stock depletion
  • Greater operational pressure in store
  • More competing promotions

Even well-planned supply chains come under strain and small execution issues become amplified.

A delay in replenishment.

A missed backroom check.

A prioritised task that shifts focus away from the shelf.

When these pressures combine, even small execution issues can have outsized impact but when availability is maintained, these same moments can become powerful drivers of incremental sales and category growth.

The Visibility Problem

The challenge with out-of-stocks isn’t just that they happen, it’s that you often don’t see them when they matter.

Traditionally, availability is assessed after the event:

  • Sales data highlights missed performance
  • Syndicated data provides a delayed view (often 4–6 weeks later)
  • Post-event analysis identifies patterns

But by the time this is understood, the opportunity has passed.

This is part of a broader challenge we explored in our article on why the World Cup is won in store, where in-store execution ultimately determines performance during major retail moments.

More specifically, it reflects the gap between planning and reality in store, something we explored further in From Plan to Reality: Why Major Sporting Events Expose the Execution Gap.

Availability vs Visibility

Most organisations already track availability at a high level.

But the question during major events isn’t just:

Was the product available?

It’s:

Was the product available at the exact moment demand peaked?

That level of visibility is rarely captured.

And without it, it’s difficult to:

  • Understand the true impact of out-of-stocks
  • Distinguish demand from execution issues
  • Identify where intervention is needed

From Stock Loss to Revenue Opportunity

Out-of-stocks are typically viewed as a loss, but they also represent a clear opportunity.

When availability is maintained during peak demand windows:

  • Promotions deliver expected uplift
  • Trade promotion spend is protected
  • Incremental sales are captured
  • Category share can increase

Maintaining availability doesn’t just protect revenue in the moment, it helps protect brand preference over time.

And the difference isn’t just supply, it’s visibility.

From Reactive to In-Window Action

The most effective teams are shifting from:

Availability → Post-event analysis

To:

Availability → Visibility → Action

This means:

  • Identifying out-of-stocks while they are happening
  • Prioritising stores with the highest demand impact
  • Acting before the peak demand window closes

This shift is what turns availability from a reporting metric into a commercial lever.

From Leakage to Growth

Out-of-stocks during major events are often seen as inevitable but they don’t have to be.

With the right visibility, they become:

  • Detectable earlier
  • Actionable in real time
  • Preventable in high-impact moments

The World Cup doesn’t just increase the risk of lost sales, it increases the value of getting availability right.

Protect Revenue When Demand Peaks

Out-of-stocks don’t just impact availability. They directly impact revenue, especially during high-demand retail moments.

Execution Intelligence provides visibility into what is happening across stores, enabling teams to identify availability issues early and act while it still matters.
