William Bonner

William "Bill" Bonner is an Operating Partner at Sequel Holdings, a Dallas-based lower middle-market private equity firm formed in 2002 that makes control investments in profitable food, beverage, agribusiness, and specialty-materials companies. Bonner joined the firm in 2015 as an Operating Partner, per Sequel's December 16, 2015 announcement expanding its team, and focuses on the firm's Food Ingredients and Processing / Agribusiness verticals. His stated areas of expertise are consumer food products, food ingredient manufacturing, and agribusiness, with a particular emphasis on product development, ingredient manufacturing, and quality.

Bonner is a career food scientist and operator rather than a traditional finance-track investor. He began his career as a food scientist at Quaker Oats, working on grain-based foods and product development, and went on to hold senior positions at M&M/Mars, Nabisco Foods Group, and ConAgra Foods. His roles have included Director of Research & Development at Mars, senior R&D leadership at Nabisco, and technical-services leadership at ConAgra Brands.

His most direct tie to Sequel's investment activity is 21st Century Grain Processing ("21C"), a Sequel portfolio company, where he served as Senior Vice President of Research and Technical Sales/Service through the firm's sale of the business to agribusiness giant Viterra. This operating history — building and running the technical, product-development, and quality functions inside a Sequel-owned food-ingredients platform — is the foundation of his operating-partner role.

Bonner earned a B.A. in Chemistry and Mathematics from Blackburn College in Carlinville, Illinois.

• Sequel takes control ownership stakes in established, profitable lower middle-market companies — this is a buyout/growth firm, not a seed or angel investor.
• Sector focus: food & beverage (primary), agribusiness, food ingredients & processing, and plastics/specialty materials.
• Size criteria: enterprise values roughly $50–150 million and businesses generating more than $5MM EBITDA.
• What earns a "yes": "successful businesses in growing categories" paired with strong management teams committed to an agreed-upon strategic growth plan; Sequel emphasizes responsible leverage and long-term value creation.
• Bonner's specific lens: deep operating diligence and value-add in food ingredient manufacturing, product development, and quality/technical operations — he is the person who assesses and improves the technical and manufacturing side of food/agribusiness targets, rather than sourcing seed deals.
