A week before Easter, someone stole a truck carrying 12 tonnes of KitKats. On Wednesday night at Cannes, the brand walked away with advertising’s top public relations award for what it did next.
The PR Lions Grand Prix at the 2026 Cannes Lions International Festival of Creativity went to “The KitKat Heist,” a campaign developed by agencies Burson and VML in London for Nestle’s KitKat brand.
The work beat out a category that drew 1,156 entries and awarded 37 Lions in total.
Thieves hijacked a shipment of 413,793 individual chocolate bars somewhere in transit between Italy and Poland, taking peak inventory days before the confectionery industry’s biggest sales weekend. The loss threatened both holiday supply and the brand’s reputation.
Rather than manage the incident quietly, KitKat broadcast it. The brand acknowledged the theft through a news release and social media statements written with wit instead of defensive corporate language. Once public interest peaked, it launched the Stolen KitKat Tracker, a digital tool that let people enter the eight-digit batch code on the back of their own bars to check whether they were holding stolen goods.
The tool turned scrollers into what the agencies called chocolate detectives. It produced more than 2.2 million engagements, flagged suspicious batch codes and surfaced at least one lead that police are investigating, according to the campaign’s case study.

The thieves and the stolen chocolate remain at large.
KitKat reported $224 million in earned media within 10 days on zero media spend, a 31% share of voice across 93 markets and more than 115 other brands joining in with their own KitKat jokes. The campaign also collected four Gold Lions and additional Silver and Bronze honors across other categories.
Dana Tahir, chief executive of Havas Red Middle East and Egypt, served as PR Lions jury president. She said crisis communications has historically been about caution and minimizing damage, and that this year’s winning work rewrote those rules.
She said the campaign did not eliminate risk but choreographed it, with every pun and quote calibrated to keep the brand on the right side of the line.
Burson became only the second PR agency to win the Grand Prix in the festival’s PR Lions category. Taj Reid, global chief creative officer at Burson, said the work stood out because it chose creativity over caution. Ryan McManus, chief executive of VML UK, said the team responded to a brief that came from the real world and enlisted what felt like the whole internet to help track down the stolen bars.
David Rennie, an executive vice president who leads the company’s strategic business units and marketing, pointed to nearly 70 years of the “Have a Break. Have a KitKat” line as the foundation that let the team move quickly when the opportunity appeared.
