Fitch Ratings has affirmed New Mountain Finance Corporation's (NMFC) Long-Term Issuer Default Rating (IDR), secured debt rating and unsecured debt rating at 'BBB-'.

The Rating Outlook has been revised to Stable from Negative.

KEY RATING DRIVERS

IDRs AND SENIOR DEBT

The Outlook revision reflects the recent decline in leverage and reduction in NMFC's target leverage range, decline in non-accruals, recognition of unrealized portfolio appreciation in 1H21 and low realized loss rate over the past year. Fitch believes the improvements in leverage and asset quality reduce the downside risk to NMFC's asset coverage cushion. Net investment income (NII) coverage of dividends declared has also improved in recent quarters.

The rating affirmation reflects NMFC's solid historical credit performance, experienced management team, shift toward first lien investments in recent years, demonstrated access to the debt and equity markets over time and access to deal flow and investment resources given its affiliation with New Mountain Capital Group, L.P.

Rating constraints include a greater reliance on non-cash income; higher-than-peer exposure to second lien and equity investments, including New Mountain Net Lease Corporation and off-balance sheet joint ventures, which could experience more valuation volatility than first lien debt investments, particularly in times of stress; and higher-than-peer leverage, including Small Business Administration (SBA) borrowings.

Rating constraints for the BDC sector include the market impact on leverage, given the need to fair-value the portfolio each quarter, dependence on access to the capital markets to fund portfolio growth and a limited ability to retain capital due to dividend distribution requirements. Additionally, the competitive underwriting environment has yielded deterioration in terms in the middle market, including fewer/looser covenants and higher underlying leverage.

Non-accrual investments accounted for 1.0% of the debt portfolio at fair value at 2Q21 and 3.1% at cost; down from recent peaks of 2.9% and 4.7%, respectively, at 2Q20. Net realized losses as a percentage of the average portfolio at value were 0.1% in 2020 and averaged 0.7% from 2017 through 2020, which were below the rated BDC peer averages. Net realized losses were slightly above-average in 1H21 driven by a loss on a restructured energy investment, but remained low at 0.3%.

NMFC's portfolio has shifted more toward first lien positions in recent years. However, first lien exposures as a percentage of the total portfolio at value were 51.6% at 2Q21, below the rated peer average. Fitch would view continued rotation into first lien positions more favorably.

Core earnings have been pressured by low interest rates and the recent portfolio rotation into lower-yielding senior investments. Annualized NII was 3.8% of the average portfolio at cost for 1H21, which was unchanged from a year ago and below peers. The weighted average yield on the income producing portfolio was 8.8% at 2Q21, up from 8.6% a year ago.

Statutory leverage, as measured by par debt-to-equity excluding SBA borrowings, was 1.19x as of June 30, 2021; down from a peak of 1.56x as of March 31, 2020. NMFC reduced its targeted statutory leverage range to 1.0x to 1.25x during 2021, which is now in-line with rated BDC peers. NFMC's leverage implied an asset coverage cushion of 19.0% as of June 30, 2021, which was within Fitch's 'bbb' category capitalization and leverage benchmark range of 11%-33%. Fitch expects NMFC to manage leverage with an appropriate cushion to account for potential for credit issues and valuation volatility.

Unsecured debt amounted to 38.7% of NMFC's outstanding debt at 2Q21, which remains within Fitch's 'bbb' category quantitative benchmark range of 35%-50% for BDCs. In January 2021, NMFC issued $200 million of five-year unsecured notes and utilized proceeds to refinance upcoming debt maturities. NMFC's nearest debt maturity is now July 2022, when $55 million of unsecured notes come due. Fitch expects NMFC to maintain unsecured debt of at least 35% of total debt.

NII coverage of dividends declared was 100.2% in 1H21, up from 97.7% in 2020. NMFC recently implemented a dividend support program, which will continue until at least Dec. 31 2022. During this time, the investment advisor has pledged to charge a base management fee of no more than 1.25% on all assets and to reduce NMFC's incentive fee, if necessary to support its dividend, which Fitch views favorably.

NMFC's cash earnings coverage of the dividend remains weaker than peers' given a high reliance on non-cash income. Paid-in-kind income amounted to 17.7% of interest and dividend income in 1H21, which was well above the peer average. Fitch believes NMFC's cash dividend coverage metrics would improve if adjusted for non-cash income accruals, which are not publicly reported. Still, failure to improve cash NII dividend coverage would be viewed negatively.

The alignment of the unsecured and secured debt ratings with the Long-Term IDR reflects solid collateral coverage for all debt classes given that NMFC is subject to a 150% asset coverage requirement.

RATING SENSITIVITIES

Factors that could, individually or collectively, lead to negative rating action/downgrade:

A decline in the asset coverage cushion to below 11%, a sustained increase in non-accrual levels, meaningful realized losses, a material change in the firm's risk profile, including a decline in first lien positions or a shift in focus toward subordinated debt and/or equity investments without a commensurate decline in leverage, a sustained increase in non-cash income at or above the current level, weaker cash-based NII coverage of the dividend and/or a sustained decline in unsecured debt to below 35% of total debt outstanding.

Factors that could, individually or collectively, lead to positive rating action/upgrade:

Strong and differentiated credit performance of recent vintages, which will be evaluated in combination with the consistency of NMFC's operating performance, asset quality metrics, investment valuations, and underlying portfolio metrics. Positive rating action would also be conditioned upon an improvement in cash earnings and dividend coverage metrics, the maintenance of leverage levels commensurate with the risk profile of the portfolio, sufficient liquidity and continued access to the unsecured debt markets. Although not envisioned, a material reduction in leverage which was not accompanied by an offsetting increase in the portfolio risk profile could also contribute to positive rating momentum.

The secured and unsecured debt ratings are primarily linked to the Long-Term IDR and are expected to move in tandem. However, a reduction in unsecured debt as a proportion of total debt could result in the unsecured debt rating being notched down from the IDR.

BEST/WORST CASE RATING SCENARIO

International scale credit ratings of Financial Institutions and Covered Bond issuers have a best-case rating upgrade scenario (defined as the 99th percentile of rating transitions, measured in a positive direction) of three notches over a three-year rating horizon; and a worst-case rating downgrade scenario (defined as the 99th percentile of rating transitions, measured in a negative direction) of four notches over three years. The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from 'AAA' to 'D'. Best- and worst-case scenario credit ratings are based on historical performance.
