LONDON, Sept. 10, 2026 (GLOBE NEWSWIRE) -- Trimontium, an institutionally backed alternative asset manager specialising in flexible capital solutions, today announced a $325 million bespoke capital solution for Authentic Restaurant Brands (“ARB”), a portfolio company of Garnett Station Partners (“GSP”). Trimontium originated and structured the investment.
The solution supports the next phase of ARB’s growth, funding the expansion of its brands within their home markets and the selective acquisition of further regional concepts. Designed around the financial and corporate objectives of GSP and ARB, the solution spans debt, hybrid and equity instruments within a single package, with capital available over time as growth opportunities are identified. The investment demonstrates Trimontium’s ability to originate, structure and execute across the full capital structure with certainty and speed, and its transatlantic origination and execution reach.
Founded in 2021 and headquartered in Austin, Texas, ARB is a platform of iconic, fortress regional restaurant brands with extraordinary customer brand loyalty – Pollo Tropical, Tavern in the Square, P.J. Whelihan’s, Mambo Seafood and Primanti Bros. – together comprising 225 restaurants, with more than $1 billion in annual revenue, over $150 million in EBITDA and four consecutive years of positive same-store sales growth. ARB’s mission is to elevate local American “hometown hero” brands with deep community roots, loyal customers and a proven business model, equipping them with the technology, data and analytics capabilities to scale without losing their local spirit.
Vlado Spasov, Founder and Chief Investment Officer of Trimontium, commented: “We are delighted to provide a bespoke capital solution to ARB, a high-quality business in a resilient industry with a differentiated model, an exceptional management team and a clearly defined expansion strategy. This is exactly the type of idiosyncratic opportunity Trimontium was purpose-built for. We are proud that GSP recognised the unique capabilities that Trimontium brings as a capital solutions partner for this transaction. Partnering alongside GSP, an investor with deep operating expertise in food service, allows us to support ARB at an important point in its development.
This investment reflects what Trimontium was built to do: serve as a long-term, trusted capital partner, working directly with sponsors and management teams to design capital around their own objectives, rather than the constraints of conventional financial products. We look forward to working closely with Alex and the ARB team over the years ahead.”
Yaroslav Syzonov, Managing Director, Investment Team, added: “This partnership showcases the breadth of Trimontium’s platform and our transatlantic origination capabilities. Rather than applying a standardised financing product, we structured a solution that blends debt, hybrid and equity within a single package, tailored to ARB’s specific growth trajectory. The ability to originate and execute an investment of this complexity from London for a US-based business and sponsor, as a single counterparty, is a testament to the team and infrastructure we have built.”
Alex Macedo, Co-Founder, Chairman and Chief Executive Officer of Authentic Restaurant Brands, said: “Our growth has always been deliberate. We buy brands people love, we keep the operators who built them and we give them the tools to scale efficiently and thoughtfully. This capital lets us do more of that, faster. Trimontium understood how we operate from the first conversation and structured their solution around what will support the business today while building in flexibility for future growth. We are excited for this next chapter.”
Simpson Thacher & Bartlett acted as legal adviser, Houlihan Lokey as valuation adviser and La Presa Partners as tax advisers to Trimontium. Kirkland & Ellis acted as legal adviser and Evercore as financial adviser to ARB.
