Here are the latest Mars Bar-related headlines I found:
- Mars completed its acquisition of Kellanova, a major deal that expands Mars Snacking’s portfolio and global reach.[1][4]
- Mars Wrigley has been criticized over a Mars Bar size cut in the UK, with reports saying bars dropped from 51g to 40g while the price stayed at 75p.[2]
- Mars also announced a series of broader corporate updates in April 2026, including a net-zero cocoa collaboration with ofi and a partnership with Strava through IAMS.[6][1]
If you mean the Mars Bar chocolate product specifically, the most concrete recent consumer-news item is the reported shrinkflation change.[2]
