Dear Fellow Stockholders:

It has been a very eventful start to fiscal 2023 in the financial markets. Much like the first quarter, there was no shortage of market moving events during fiscal Q2. For example – the second quarter began with the collapse of several large regional banks and ended with concerns about the potential for the United States to default on its debt obligations. Notwithstanding these events, the broader equity markets have performed well thus far in fiscal 2023.

The energy sector (including energy infrastructure) has reported strong operating and financial results during the year, but equity performance for these companies has lagged the broader markets. Importantly, nothing has changed in the energy infrastructure sector’s fundamentals to alter our constructive outlook. Further, the parallel trends of energy security and energy transition – both of which are beneficial for energy infrastructure companies – have only grown in importance during the year.

Focusing on where things stand today: inflation, interest rates and the state of the global economy are three topics front and center in investors’ minds. Central banks across the globe (including the Federal Reserve) remain focused on addressing higher-than-desired levels of inflation, and market participants continue to weigh the impact this will have on economic activity. Our outlook for the remainder of fiscal 2023 is cautious, but we do not believe a meaningful (or prolonged) downturn in the economy is likely.

In this quarterly update, we discuss the energy infrastructure markets, KYN’s portfolio positioning, and the Company’s year-to-date performance. We believe the Company’s portfolio investments are attractively valued and positioned to generate compelling risk-adjusted returns for investors. Equally important, KYN’s balance sheet is well positioned to deal with higher levels of market volatility. As it relates to fiscal Q2:

· KYN’s Net Asset Return for fiscal Q2 (negative 3.5%) was weak on an absolute basis, though KYN continues to outpace its benchmark on a fiscal YTD basis (outperformed benchmark by 90 basis points);^(1)(2)(3)

· KYN’s portfolio investments announced solid Q1 2023 earnings and 2023 outlooks during the quarter; and

· KYN maintained conservative leverage levels with ample downside cushion⁽⁴⁾

Market Conditions

Fiscal Q2 was a very strong quarter for broad equity indices, with contributions from large cap technology stocks more than offsetting weak performance from other industries (including the energy sector).

Total Return
	S&P 500			DJIA			NASDAQ			XLE(6)			AMNA(7)			KRII(8)			XLU(9)
Fiscal Q2 2023		5.7	%		1.4	%		13.2	%		-7.5	%		-3.2	%		-1.1	%		0.6	%
Fiscal 2023(5)		3.3	%		-3.9	%		13.3	%		-14.2	%		-8.2	%		-5.0	%		-7.7	%

The yield curve remains stubbornly inverted, and elevated short-term interest rates have made money market funds a comparably attractive place to invest capital. Notwithstanding the inverted yield curve’s “signal” of a pending recession, domestic economic growth continues to exceed expectations and the job market remains robust. Taking the Fed’s comments at face value – and their stated desire to bring inflation back in line with its stated 2% target – reductions to the Fed Funds rate are unlikely to happen any time soon.

Crude oil prices were rangebound during fiscal Q2, mostly trading between $70 and $80 per barrel and ending the quarter below the bottom of this range ($68 per barrel). Oil prices have declined meaningfully on a year-over-year basis (down 40%) and are approximately $56 per barrel less than peak 2022 levels. Oil markets continue to be driven by three primary factors: (1) Russian supply, (2) Chinese demand, and (3) OPEC+. Russian exports continue to be more resilient than expected, while Chinese demand is rebounding more slowly than expected. With both of these factors weighing on oil prices, OPEC+ has continued to take actions to support prices, including another surprise production cut of 1 MMbbl/d in early June and an extension of voluntary cuts through December 2024. More recently, events in Russia highlight the importance of energy security and the potential for meaningful disruptions in global exports of crude oil. We expect global inventories to draw in the second half of 2023 and our outlook for crude prices over the next few years remains constructive.

Natural gas prices continued to languish on mild weather, as Henry Hub spot gas prices traded down to ~$2.00/MMBtu and stayed at that level for most of the quarter. The forward curve, however, remains much higher at ~$3.50/MMBtu in 2024 and ~$4.00/MMBtu in 2025. European and Asian gas prices fell to 2-year lows during the quarter as mild winter weather and steady supplies of LNG from the U.S. enabled European inventories to remain at comfortable levels. That said, the global gas market remains delicately balanced. LNG continues to flow from domestic export facilities at full rates, and there is little margin for error in the supply/demand balance. Any supply disruption or spike in demand would cause international prices to meaningfully increase.

Portfolio and Performance

Returns across KYN’s three energy infrastructure sectors – midstream, U.S. utilities, and renewable infrastructure – were down or flat during the second quarter of fiscal 2023. U.S. utilities were on track to outperform the S&P 500 as investors sought safety amid regional banking concerns, but a sharp May downturn (-6%) on expectations for more hawkish actions by the Fed erased this outperformance.

Comparison of Returns in Fiscal Q2 2023

KYN Net Asset Return(1)	-3.5	%
KYN Benchmark(3)	-2.4	%
Midstream(7)(10)	-3.2	%
Renewable Infrastructure(8)	-1.1	%
U.S. Utilities(9)	0.6	%

KYN generated a total Net Asset Return of negative 3.5% in fiscal Q2. While we are disappointed in the absolute return for the quarter, on a fiscal YTD basis we continue to outperform the KYN Benchmark by 90 bps (following 820 bps of outperformance in fiscal 2022).⁽²⁾

KYN’s Market Return, which is based on stock price performance rather than Net Asset Value, was negative 9.0% for fiscal Q2.(11) This trailed our Net Asset Return as our stock price traded at a 16.5% discount to NAV as of May 31^st compared to a 11.4% discount at the beginning of the fiscal quarter.

The fundamentals driving our long-term return expectations for KYN’s portfolio investments are not overly influenced by near term economic headwinds or challenging capital markets. These energy infrastructure companies generate significant free cash flow and, consequently, are able to self-fund capital expenditures and dividends. Further, their cash flows are resilient and predictable. No sector (or company) can be completely insulated from volatility in the financial markets or an economic downturn, but the attributes of our core investment universe – midstream, renewable infrastructure, and U.S. utilities – give us confidence that these businesses are better positioned than other sectors to “weather the storm.” Thus far in fiscal 2023, we have increased KYN’s exposure to the midstream sector (85% of the portfolio) and decreased the Company’s exposure to renewable infrastructure and utilities. Within the North American energy infrastructure sector, we are most bullish on the outlook for midstream companies.

Distribution & Outlook

Given KYN’s strong performance during fiscal 2022 and our outlook for the next 12 to 18 months, in March we announced a 5% increase in our quarterly distribution (to $0.21 per share). Earlier this month, KYN declared a 21 cent per share distribution to be paid to investors in early July. Once the combination with KMF is completed, we intend to recommend an additional one cent per share increase in KYN’s quarterly distribution rate (to $0.22 per share, representing a cumulative 10% increase).

KYN & KMF Proposed Merger

KYN and Kayne Anderson NextGen Energy & Infrastructure, Inc. (NYSE: KMF) announced plans to combine the two funds earlier this year (the “Merger”), with KYN as the surviving entity. The Merger is subject to stockholder approval, and KYN and KMF expect to mail a definitive joint proxy statement/prospectus to stockholders that will contain information about the Merger, including the date of the special meeting, following a review period with the SEC.⁽¹²⁾ Please refer to kaynefunds.com/insights for information on the Merger.

We continue to work towards the completion of this proposed combination of KYN and KMF and firmly believe this transaction enhances KYN’s ability to capitalize on the long-term tailwinds in the energy infrastructure sector. Stockholders in the combined entity will continue to have exposure to the largest macro trends in the energy industry, and the fund will be managed by the same dedicated team of professionals committed to providing attractive risk-adjusted returns and best-in-class financial disclosure.

We encourage investors to visit our website at kaynefunds.com for more information about the Company, including the commentary posted on the “Insights” page that discuss performance, key industry trends, and the Merger. We appreciate your investment in KYN and look forward to providing future updates.
