Who owns Cheez It?

Could you clarify for me who exactly owns the popular snack brand Cheez It? Is it a publicly traded company, or is it privately held? Are there any notable investors or stakeholders involved in the ownership structure? And furthermore, have there been any significant changes in ownership over the years that have impacted the brand or its products? I'm interested in understanding the business side of Cheez It, and how its ownership may have contributed to its success.
