Sale Represents Successful Exit Following Significant Earnings Growth and Value Creation During Southfield’s Period of Investment Greenwich, CT – June 3, 2026 – Southfield Capital (“Southfield”), a premier lower middle market private equity firm, announced today that it has completed the sale of Milrose Consultants (“Milrose” or the “Company”), a leading national provider of code consulting, permit expediting, architecture and engineering, inspection services, and municipal real estate compliance solutions, to Littlejohn & Co. (“Littlejohn”). Terms of the deal were not disclosed. Since partnering with Southfield in 2019, Milrose has achieved significant growth, expanding from a NYC focused company to a leading nationwide provider with over 435 professionals operating from offices in all 50 states. During that time, Milrose increased its earnings by over 7x through the expansion of its sales platform, broadening its services offerings, recruiting a highly-talented management team, and successfully executing 14 strategic add-on acquisitions. Key members of the management team will remain shareholders in partnership with Littlejohn. Southfield’s continuation vehicle transaction with Milrose in 2023 provided existing investors with optional liquidity while reaffirming its conviction in the Company’s strong market position and management team’s long-term strategic growth vision. The sale to Littlejohn represents a successful exit for Southfield’s investors. “Southfield has been an exceptional value-add partner and trusted advisor throughout our time working together,” said Dominic Maurillo, CEO of Milrose since 2021. “Their thoughtful and collaborative approach, together with an unwavering commitment to investing in our people and infrastructure, have helped position Milrose for long-term success. We are grateful for their support and have appreciated their ability to provide a consistently valuable perspective while empowering and trusting us to execute on our growth and operational strategy.” “It has been a pleasure partnering with Dom and the entire Milrose team over the past several years,” said Chris Grambling, Partner at Southfield. “Together, we executed on a shared vision to scale the platform by expanding geographically, broadening the Company’s service offerings, and completing a number of strategic acquisitions to help evolve Milrose into a national leader in building code compliance and consulting. We are proud of what we accomplished alongside Milrose’s management team and believe the Company is well positioned for continued success in the next phase of its growth.” Solomon Partners served as lead financial advisor, Houlihan Lokey served as financial co-advisor, KPMG USA provided transaction advisory services, and Wiggin and Dana LLP served as legal advisor to Milrose in this transaction.

Institutional Partnership with Southfield to Further Metric’s Expansion and Acceleration of Global Footprint as a Market Leader in the Specialist Search & Recruitment Space Greenwich, CT – March 24, 2026 – Southfield Capital (“Southfield”), a premier lower middle market private equity firm, today announced that it has made a majority investment in Metric Search, Ltd. (“Metric,” or the “Company”), a leading specialized provider of talent solutions and human capital placement services for niche, high-growth sectors, including MedTech, life sciences, engineering, and data centers. Founded in New York in 2019, Metric has quickly established itself as an industry leader in the executive search and talent solutions space with over 130 consultants globally across seven offices in the U.S. and UK. The Company, which delivers senior and executive-level search through four specialist sub-brands – Metric Geo (Engineering and Infrastructure), Metric DCX (Data Centers), Metric Bio (Life Sciences and MedTech), and Metric Exec (C-suite and PE-backed executive search) – has been recognized in the Financial Times FT1000 list of fastest-growing companies in both 2025 and 2026. Metric Founder & CEO, Joe Jani, will remain in his position as part of the firm’s management team and work alongside Southfield to continue executing on the next phase of the Company’s ambitious growth strategy. Joe Jani commented, “This is a defining moment, not because of the capital, but because of what it represents. Every decision we have made since 2019 has been about staying disciplined, staying specialist, and earning the trust of the clients and candidates we work with. Our sectors, Data Centers, Life Sciences, Infrastructure, and Engineering, are at the center of the most important capital flows in the global economy, and the cost of getting talent wrong in those markets is high. Metric exists to solve that problem, and with Southfield’s backing we now have the platform, the resources, and the team to do it at scale.” Metric’s strong management team, specialized micro niche-focused service strategy, unique internal recruitment and training model, and strong client value proposition, position it to continue capitalizing on the emerging imbalances across the labor market. Partnering with Southfield now provides Metric with significant runway and support for both organic and inorganic growth within the highly fragmented industry, while also expanding its service offerings to better serve their current and future clientele. “We were immediately impressed by the differentiated offering Metric has created since its founding in 2019, especially in a market that is often commoditized,” said Chris Grambling, Partner at Southfield Capital. “Their focus on sectors with structural talent scarcity, together with their depth of expertise and track record within those sectors, has allowed them to establish an exceptional, best-in-class, and highly scalable platform. We are excited to be partnering with Joe and the rest of the Metric team as part of their ambition to be a global leader in the specialist executive search space.” Having invested in more than 100+ entrepreneur-built businesses since 2002, Southfield’s majority investment in Metric is the third platform made from its current flagship fund, Southfield Capital IV. Tree Line Capital Partners provided debt financing. Finn Dixon & Herling LLP and Simmons & Simmons LLP provided legal counsel to Southfield. Houlihan Lokey acted as the exclusive financial advisor to Metric.
