Mars Snacking to close Newark office, affecting 307 employees; Hackettstown operations to continue
NEWARK, N.J. (Essex County) — Mars Snacking will close its Newark Market Hub by December 2027 as part of a broader effort to consolidate its North American office footprint, the company told RNJ.
The announcement follows a Worker Adjustment and Retraining Notification (WARN) filed in July, which lists an effective date of Oct. 16, 2026, and indicates that 307 employees will be affected.
“Following a comprehensive review of our Mars Snacking North American office footprint, we will be sunsetting the Newark Market Hub for Mars Snacking Associates by December 2027, consistent with our previously communicated move to Chicago. This decision is part of our broader strategy to position Mars Snacking for long-term growth and strengthen our operations in key locations across North America.”
Mars Snacking said it recognizes the impact the closure will have on employees in Newark and is committed to supporting them through the transition, including providing relocation opportunities and other assistance where appropriate.
M&M’S have been produced at the company’s High Street plant in Hackettstown since 1958, with millions of the iconic candies manufactured there each day.
Mars Snacking said it remains committed to New Jersey and will continue investing in its operations, including ongoing innovation and manufacturing work in Hackettstown.
The company also said it expects to continue serving customers and consumers without disruption during the transition.
