Goldman Sachs BDC 's ( GSBD - Free Report ) shares have gained 2.2% since the announcement of third-quarter 2021 results late last week. Net investment income of 63 cents per share beat the Zacks Consensus Estimate of 48 cents. This included purchase discount amortization of 15 cents per share related to its merger with Goldman Sachs Middle Market Lending Corp in October 2020. The results benefited from a drastic improvement in total investment income. Rise in net asset value and a solid investment portfolio balance also offered support. However, an increase in operating expenses was a headwind.
