Big food companies have continued reshaping office footprints and consolidating corporate operations in 2026 as they weigh investment, staffing, and location strategy. In New Jersey, that shift now includes Mars Wrigley, the candy maker behind M&M’s and Snickers, which is preparing to leave its Newark headquarters. The move affects hundreds of employees and marks another major headquarters loss for the state.
Mars Wrigley filed for 307 Newark layoffs as it prepares to exit
Mars WrigleyConfectionary US, LLC is cutting 307 jobs in Newark, according to the New Jersey Department of Labor and Workforce Development’s 2026 WARN notice archive. The state filing lists Newark as the affected city, July as the month posted, an effective date of October 16, 2026, and a workforce impact of 307. News 12 reported on July 19, 2026, that layoffs at the Newark facility were scheduled to begin on that date.

Reports tying the filing to Mars Wrigley’s headquarters closure say the affected site is the company’s Newark office at 110 Edison Place. Coverage from Jersey Digs said the headquarters departure will end the company’s Newark office presence less than a decade after Mars expanded there. The company had previously made Newark a major corporate base as part of a larger New Jersey footprint.

Public reporting has identified the departing headquarters as 110 Edison Place, near the Prudential Center area, making the layoff notice especially significant for downtown Newark’s office market and for workers tied to that site. The state’s WARN archive does not list separate counts for other New Jersey municipalities in this filing…
