Thanks, Mike. We invested in 2 new portfolio companies this quarter as well as 3 existing portfolio companies. We fully realized our positions in 5 portfolio companies and also refinanced our position in Gexpro and fully realized our position in the Fusion exit loan. We invested in the first lien loan of AHF Products, which supported the LBO by Paceline Equity Partners. AHF Products is a leading producer of hard surface and solid wood flooring in North America. Our yield to cost is approximately 7.4%.
We made our second equity co-investment alongside Investcorp's North American Private Equity Group. S&S Truck Parts LLC, listed in our scheduled investments as Pegasus Aggregator, is one of the largest suppliers of new aftermarket parts for medium- and heavy-duty vehicles. In terms of investments in current portfolio companies, our existing loans at Gexpro was refinanced in January as part of a larger transaction which backed several acquisitions. Our yield at cost on Gexpro's funded revolver is approximately 7.5%, and term loan and delayed draws approximately 7.4%.
We also made an additional investment in the equity of Techniplas to support an asset purchase of a molded product facility sold by Lyle Industries. As part of Fusion's restructuring process, we were a joint lead arranger on the new first lien term loan, which has a yield at cost of approximately 9.6%. We also participated in the company's new Series A preferred equity, which has a PIK coupon of 12.5% and a yield at cost of approximately 13.1%. Mike will provide additional detail about Fusion's restructuring later in the call.
Turning now to our realizations. Our loans at Gexpro was repaid in full as the company refinanced in January. Our fully realized IRR was approximately 10.4%. Our second realization was ProFrac Services. ProFrac completed the acquisition of FTS International in March, and we were refinanced out of our position. Our fully realized IRR was approximately 9.9%. We also received repayment in full for Fusion's exit loan as the position was refinanced through the broader restructuring of the company. Our fully realized IRR was approximately 14.1%.
We exited several investments opportunistically this quarter in order to reduce our leverage and rotate into higher-yielding credits. We fully realized our position in Veregy with an IRR of approximately 9.7%, [ QualTech ] with an IRR of approximately 8.7%, Flow Control with an IRR of approximately 8.1% and Galaxy with an IRR of approximately 7.2%. After quarter end, we invested in one new portfolio company, one existing portfolio company, and had 2 realizations in existing portfolio companies. First, the new Gexpro loans made in the first quarter were repaid in April as the company merged with Lawson Products.
Our fully realized IRR on the term loan was approximately 19.7%. Although we are pleased with the return on the revolver and the delayed draw, the IRRs are not meaningful given the short holding period. We invested in the club financing for American Nuts, which supported the refinancing of the company and the acquisition of [ DSD ] Merchandisers. American Nuts provides procurement, processing and packaging services of nuts, seeds and dry fruits. The acquisition of [ DSD ] Merchandisers creates a fully vertically integrated business. Our yield at cost is approximately 9.9%.
Lastly, we fully realized our position in Klein Hersh, as the company simultaneously refinanced its loans and convert it to an ESOP. Our fully realized IRR was approximately 11.8%. We also invested in a new transaction. Our yield to cost is approximately 9.2%. Using the GICS standard as of March 31, our largest industry concentration was trading companies and distributors at 9.5%, followed by IT services at 9.2%, Internet and direct marketing retail at 9.0%, professional services at 7.8% and household durables at 7.1%. Our portfolio of companies are in 20 GICS industries as of quarter end, including our equity and warrant positions. As of March 31, we had 35 portfolio companies, a decrease of 3 from December 31. I'd now like to turn the call over to Rocco to discuss our financial results.
