Golub Capital BDC (GBDC) experienced a pre-market plunge of 5.12% on Tuesday, as investors reacted to the company's involvement in a major financial transaction.

The decline comes as Golub Capital was named as a co-leader in a $790 million single-asset continuation vehicle for Solace Systems Inc., a real-time data and agentic AI platform. The transaction, which also involves Apogem Capital, HSBC Asset Management, and Schroders Capital, represents a significant capital commitment that may have raised concerns among investors about the company's capital allocation and risk exposure.

Bridge Growth Partners, which initiated the continuation vehicle, will see its stake exceed 15% of total equity post-closing, while existing investor Healthcare of Ontario Pension Plan rolled over its equity position as part of the transaction.
