Private equity sponsors operating in the lower middle market face a changing financing landscape. Banks have retreated, and private credit has filled the gap, but lenders vary widely. Many larger credit platforms prioritize volume over execution quality, neglecting complex smaller deals. And when a lender re-trades or misses a commitment, the sponsor pays the price.
The scale of this shift is documented. According to Ropes & Gray, direct lending accounted for 90% of lower middle market LBO financing in 2024, up from just 36% in 2014. As direct lenders have come to dominate this space, transaction certainty is becoming a central issue. With roll-up strategies now accounting for over 80% of all lower middle market deals, per Cherry Bekaert, each add-on acquisition demands a lender who knows the sponsor, knows the sector, and can commit to terms that hold through close. A re-trade at the term sheet stage costs time, but a re-trade in the final days of a transaction can destroy a deal that took months to build.
To address the execution gap in lower middle market lending, Abacus Finance Group is expanding its sponsor coverage and deepening its focus on relationship-driven, certainty-of-close financing for private equity-backed acquisitions and recapitalizations. Founded in 2011 and headquartered in New York, the firm has closed billions in financings across more than a decade of lower middle market transactions.
The firm’s lower middle market lending model is built around relationships. Abacus Finance Group constructs custom cash flow-based senior financing solutions for each transaction, beginning with the sponsor’s goals and structuring backward to fit the business. The team maintains direct communication throughout the life of every deal. Sponsors aren’t handed to a coverage banker and then routed through a credit committee that has never met them. The same team that underwrites a deal closes it.
Abacus Finance Group brings 125+ years of combined leveraged finance experience to each transaction. The company has financed acquisitions, add-ons, recapitalizations, and growth financings for sponsor-backed companies throughout the United States. Multiple sponsor partners report working with the firm across more than a decade of transactions. This relationship-driven model shows up in the firm’s recent work. In mid-2026, Abacus served as sole lender and administrative agent on the senior debt financing behind Achieve Partners’ investment in Celito Tech. Achieve Managing Director Aanand Radia noted that Abacus delivered the certainty Achieve was looking for in a financing partner and closed the transaction on a tight timeline.
