New Mountain Finance Corp belongs to the Finance & Banking sector. Filings by its managers are published through SEC (Form 4). Between 18 October 2025 and 18 October 2026, 6 insiders published 10 filings.
Not one open-market sale was filed. On the buying side, 4 insiders reported 8 purchases totalling €2.4M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. At €567k, the purchase published on 5 March 2026 by Klinsky Steven B is the largest of the period. The buyers include 4 senior executives.
With 10 filings in twelve months, the company is quieter than the median of 22 filings across the 5,458 companies we follow on the same exchange. Our records for New Mountain Finance Corp go back to 2016, with 66 purchases and 2 sales on the open market in total. For the fiscal year to 31 December 2025, the annual 10-K puts net income at 16.5 m USD, and the dividend at 1.28 USD per share.
In the case of 7 purchases, another manager of the company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last purchase on record was published on 18 March 2026, which is 214 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4.
For comparison within the same sector, see the insider buying recorded at First Guaranty Bancshares, Inc. and BCB Bancorp Inc. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.

New Mountain Finance Corp. (NYSE/NASDAQ: NMFCZ) is a U.S.-based specialty finance company focused on private credit and structured lending. It is organized as a business development company (BDC) and is headquartered in New York, United States. The platform is closely associated with New Mountain Capital, a New York-based investment firm known for a sector-focused, “business building” approach. New Mountain Finance was incorporated in 2010, while its credit business dates back to 2008, giving it a long operating history in sponsor-backed middle-market lending. ([newmountainfinance.com](https://www.newmountainfinance.com/?utm_source=openai))
At its core, the company provides direct lending solutions to U.S. upper middle market companies, typically through first-lien and other senior secured credit structures. Management describes its mandate as targeting high-quality, defensive growth businesses that are well researched by New Mountain. In practice, the portfolio has repeatedly shown meaningful exposure to software, business services, healthcare-related businesses, and other recurring-revenue or mission-critical service categories. That mix is designed to support current income, preserve downside protection, and align with the risk profile sought by income-oriented investors.

From a competitive standpoint, NMFCZ operates in the highly competitive U.S. direct-lending market, where listed BDCs and large private credit managers compete for sponsor-backed transactions. Its differentiation comes from the New Mountain Capital platform, deep sector specialization, and a disciplined focus on companies backed by top private equity sponsors. This gives the firm access to proprietary or relationship-driven deal flow and supports a more selective underwriting posture than many broad-market lenders. The company’s business remains primarily U.S.-focused, with no meaningful international operating footprint disclosed in recent materials. ([newmountainfinance.com](https://www.newmountainfinance.com/news-events/press-releases/detail/214/new-mountain-finance-corporation-announces-december-31?utm_source=openai))
Recent developments underscore a fairly active capital-markets and reporting calendar. New Mountain Finance announced its first-quarter 2026 results on May 4, 2026, and the company’s investor relations pages show recent SEC filing activity, including Form 4 insider transaction reporting. In addition, the company priced $300 million of 6.200% unsecured notes due 2027 in 2024, which highlights ongoing balance-sheet management and access to the public debt market. For investors in France, Belgium, or Switzerland, the key takeaway is that NMFCZ offers exposure to U.S. private credit through a listed vehicle on the American market, with its corporate headquarters in New York, United States.
