We will review two companies that have impacted portfolio performance but that we have not recently discussed.⁵

Holcim/Amrize has performed well on the back of strong business performance and a strategic decision to separate the company’s North American operations. The North American operations have taken the name Amrize and have a US listing (NYSE: AMRZ). We are pleased to see former CEO Jan Jenisch return to lead the North American business.

International Flavors & Fragrances strengthened its balance sheet through a series of asset sales. Since the beginning of 2024, new management has consistently delivered or exceeded financial targets. Despite these positive developments, the company’s shares have re-rated lower, and the stock price has declined.

The first half of 2025 brought higher volatility, with the MSCI ACWI and S&P 500 declining by 16.3% and 18.9%, respectively, in a few days in April from their February peaks. For some people, such dramatic movement implies greater risk, but when viewed over a longer horizon, we believe such an opinion becomes harder to defend.

Anchoring to daily pricing fluctuations can cause unnecessary stress and lead to decisions that may reduce investment returns. Instead, internalizing the importance of a longer time frame should help reduce the stress caused by market volatility. We believe we have successfully and consistently applied the discipline of looking to a longer time frame through market swings in our management of the Fund.

Life offers little certainty, so we expect uncertainty and build models that reflect a range of potential outcomes: Low, Base, and High. We often have opportunities to acquire good businesses that have bad news and very low expectations for future performance incorporated into their stock prices. To the extent that these businesses exceed these low expectations, we expect to be rewarded. We have operated in this manner for nearly a decade and will continue to do so. Importantly, the world is neither more nor less certain today than it was before Liberation Day. A cogent philosophy, clarity of thought, practiced execution, and repetition should enable us to navigate an ambiguous future, much like the directions you will find on shampoo bottles: “Wash, Rinse, Repeat.”

We continued to trim positions in 2024 and early 2025 in response to elevated valuations, resulting in increased cash as we await opportunities. After President Trump announced his Liberation Day tariffs on Thursday, April 2, 2025, global markets plunged, but just a few trading days later, they significantly rebounded. A stock market drawdown that lasts only a few days is too short a timeframe to materially shift the portfolio. Despite the brevity of the decline, we did selectively redeploy some capital in a few high-conviction positions.

Valuations remain above average, partly justified by lower-than-average interest rates. US companies continue to trade more expensively relative to their historical average and when compared to those based outside the US, which supports our continued interest in investing overseas.

When people become excited about market prospects, they tend to assume more risk, which can manifest in the form of paying a higher multiple, increasing risk exposure, or sometimes using leverage (e.g., through debt or derivatives). We see that happening today. This year is the second-largest inflow year into leveraged equities as of June 10th, and the year isn’t over yet.10 Other speculative indicators help explain today’s rising stock prices. Riskier option volumes have hit new highs (e.g., 0DTE)11. Retail investors have helped lead the charge, ramping up their investments in leveraged equity funds. Retail investors are also buying more stocks on margin (FINRA margin debt has more than doubled in the last five years).12

Broader risk-taking seems less appropriate to us given the current elements of speculative excess combined with relatively high market valuations. The Fund’s equity risk exposure has generally moved in inverse proportion to the market. When stock prices rise, exposure decreases, and conversely, when stock prices decline, exposure increases. This is a generalization, as sectors sometimes exhibit performances and valuations that deviate from the market as a whole. Before the recent market correction, the Fund’s net equity exposure dropped to a recent low of 38.0%. We then purchased equities during the market weakness, which caused net equity exposure to increase moderately to 40.9% at quarter-end.

As far as closed-end funds go, Source utilizes an unusually wide range of tools and approaches to seek to solve various problems effectively. We endeavor to avoid the cognitive bias of over-reliance on any one method. If it’s raining, for example, we’re looking for our umbrella, not our sunscreen.

Our exposure to different asset classes, regions, industries, market capitalizations, etc. shifts as a function of opportunity. For example, we believe that the intersection of risk and reward is more attractive today in small and medium-sized companies and explains the current attention we have paid to this area. Excessive attention to one area can create opportunities in another, which we believe is the case with small- to midcap (SMID) shares versus large-cap. Large-capitalization stocks, particularly those that are “growthier,” have captured the minds and wallets of investors and now trade at unusually high valuations that do not afford the downside protection we prefer should either growth be less than expected or valuation multiples contract.

Returns & Valuations by Style14

Fixed Income

Traditional

On April 2, the federal government announced significant tariffs on imports into the United States that initially increased the effective tariff rate on U.S. imports to levels not seen since the 1930s. Driven by uncertainty created by a subsequent series of escalating, retaliatory tariffs and associated rhetoric, interest rate volatility increased significantly and credit spreads increased. A 90-day pause on tariffs announced in April drove a subsequent reduction in volatility and decline in spreads.

In the week following April 2, spreads on high-yield debt increased significantly before returning to and then declining below pre-tariff levels. The chart below shows the spread on the BB component of the Bloomberg Barclays High Yield Index, excluding energy. We find this measure of the high-yield market to be a better indicator of historical pricing in the high-yield market because it removes some of the distortions associated with changes in the composition of the overall high-yield index. Between April 2 and April 9, spreads on these BB-rated bonds, excluding energy, reached a peak of 317 bps, representing the 69th percentile of the available history. For reference, the spread on the overall high-yield index reached a peak of 476 bps during that time, representing the 48th percentile. At June 30, the spread on the BB index, excluding energy, was 199 bps, and the spread on the overall high yield was 323 bps, both representing the 6th percentile of their respective histories.

Judging only by the spread, for a brief moment in early April, the high-yield market looked like it was abnormally cheap, or at least reasonably priced. However, higher uncertainty typically demands a higher expected return, and lower uncertainty typically earns a lower expected return. Returns have become more uncertain due to tariffs. As a result, despite higher potential returns, we did not generally find compelling investments for the Fund during the tariff-induced market turmoil. During that period in early April, we invested in a high-yield bond that we had previously researched. After refreshing our underwriting following the announcement of tariffs, we were able to buy that bond at a price that we believe offered an attractive return for the risk.

Private Credit

Source has 25.1% committed to private credit (including called and uncalled capital) as of quarter-end. We continue to look for opportunities to increase that exposure.

Corporate & Other

Distribution

On May 29, 2025, the Fund’s Board approved maintaining the current rate of 20.83 cents per share for its regular monthly distribution through August 2025.16 This equates to an annualized 5.76% unlevered distribution rate based on the Fund’s closing market price on June 30, 2025.

Discount to NAV

The Fund’s discount to NAV closed at 5.61% at quarter-end. The average discount to NAV for the trailing twelve months was 4.74%.17

Closing

While we cannot guarantee performance results, we assure you that we will continue to move forward with the same philosophy and process, aiming to deliver an attractive rate of return with a focus on downside protection.18
