William Blythe, a global leader in the development and manufacture of specialty inorganic chemicals, has agreed to combine with MAC (Metals and Additives LLC), a US-based specialty chemicals company. The combination creates a unique, international platform focused on regulated and mission-critical applications, with leading positions in flame retardants and smoke suppressants. 

H2 carved out William Blythe in May 2025. Within 15 months, this transaction creates a business of significant scale with revenues of over $160 million. The combination has global reach with revenues derived approximately 50% from North America, 30% from Europe and 20% from APAC.

The combination of William Blythe and MAC is another example of H2 successfully navigating carve-out and deal complexity and providing hands-on support to create a new market leader.
