Capitolis agrees to acquire eSecLending for $200 million in its fourth deal in five years
The all-cash acquisition folds eSecLending’s securities lending and collateral management business into Capitolis’s financial resource optimization platform, with seller Parthenon Capital also investing in Capitolis as part of the transaction.

Capitolis, a financial technology company focused on optimizing balance sheet and counterparty risk for banks and institutional investors, has agreed to acquire eSecLending, a securities lending and collateral management firm, for $200 million in an all-cash transaction.
The deal is Capitolis’s fourth acquisition in five years as it builds out its financial resource optimization platform, which helps large financial institutions manage capital, collateral and counterparty exposure more efficiently. Integrating eSecLending’s securities lending and collateral management capabilities extends that platform into a business line Capitolis did not previously operate directly.
Capitolis is purchasing eSecLending from private equity firm Parthenon Capital and the target company’s management team. As part of the transaction, Parthenon Capital is also making a new investment directly into Capitolis, a structure that keeps the seller with an ongoing financial stake in the combined business. The deal excludes eSecLending’s European entity, eSecLending (Europe) Limited, which is not part of the transaction.
The acquisition remains subject to customary closing conditions, including regulatory and antitrust approvals, and the companies have not disclosed an expected closing date. Neither party disclosed eSecLending’s current assets under management or lending volume alongside the announcement.
