“Our top performer in the second quarter was ICON plc (ICLR), which gained 57%. The surge followed the release of ICLR’s delayed year-end and first-quarter results, which provided clarity on the accounting issues that had previously weighed heavily on the stock ICLR had been the Value Fund’s largest detractor in the first quarter, after announcing in February that it would delay its year-end results and restate its 2023 and 2024 financial statements due to revenue overstatements. The stock plummeted as investors rushed to sell amid the uncertainty. We spent the next 24 hours reviewing the company’s disclosures and examining the allegations in a whistleblower lawsuit. We concluded that ICLR’s ability to generate $1 billion of free cash flow was unlikely to be materially affected and that these issues would not affect its customer relationships. With the stock trading at a free cash flow yield of approximately 15%—despite remaining, in our view, a high-quality business with attractive growth prospects— we decided to materially increase our position.”

“ Applied Materials (AMAT) traded up with the rest of the wafer fab equipment (WFE) providers on a strong 2Q26 report and forward guidance. Investors have become increasingly confident that 2027 and 2028 will both be solid growth years for WFE sales providing further visibility into AMAT’s outlook. ICON Plc (ICLR) completed its accounting review investigation with a final impact on booking and revenue recognition far less than feared, with no impact to profits and cash flow.”

ICON plc (ICLR) – ICLR shares rallied during Q2 recovering sharply from first quarter weakness following the completion of the internal investigation into its revenue recognition policies.”

“The share price of Irish contract research organization ICON (+57%) also made a significant positive contribution as the company resolved a revenue recognition restatement— an accounting correction that, while material in regulatory terms, had little impact on the company's operations, cash flows or customer relationships.”
ICON - March 2026
“Companies such as Expedia Group, Inc (EXPE), Willis Towers Watson (WTW), ICON Plc (ICLR), Fidelity Information Services (FIS), and CBRE Group, Inc (CBRE) all sold off during the first quarter on the potential long-term risks of artificial intelligence’s impact on the business models. We are certainly not trying to be myopic as it relates to AI and recognize that each company/sector has its nuances, but due to either regulatory issues, high switching costs, or human capital intensity, we believe the market may have over corrected in many of these cases. We would be remiss not to mention that the Energy sector had one of its strongest quarters in recent memory on the back of the Unites States capturing Venezuelan president Nicholas Maduro and his wife in January and the start of the Iran War midway through the quarter. This drove a 76% rise in the price of crude oil during the period. A statistic that caught our attention was the fact that the S&P 500® Energy Index (XLE) closed higher a record 14 consecutive weeks in a row, meaning the last time the XLE had a negative performance week was 2025. The XLE is now one of the best performing S&P 500® Index sectors over the trailing twelve-month period. While our Energy holdings performed well (up 30%) they were not able to keep pace with the 38% return of the Russell 1000® Value Energy Index as the more price sensitive exploration & production companies tend to be the initial beneficiaries of an immediate rise in commodity prices vs services companies such as SLB Limited (SLB) and Weatherford International (WFRD). Financials, Health Care, Materials, and Utilities were the leading sources of underperformance for the Fund during the third quarter. Both KKR & Co (KKR) and Equitable Holdings (EQH) were weak as investor worries around the private credit ecosystem accelerated during the period. We eliminated our position in Equitable Holdings (EQH) near the end of the quarter due to a capital allocation decision that violated our thesis. Along with many names in the payments/fintech space, Fidelity Information Services (FIS) also came under pressure due to AI-related fears and the potential disruption to the business long-term. Given the high switching costs and regulatory driven nature of the banking industry, we believe that these displacement fears are overblown. Within Health Care, performance reversed the fourth quarter’s positive trend and our overweight to the sector was a drag on performance for the Fund. The bulk of our underperformance was driven by Icon Plc, which similar to FIS and other names in the Fund was hit by AI related fears as well as the announced accounting investigation regarding revenue recognition over the last three years. While disappointing on the surface, we feel that the current price more than reflects each of these risks going forward and we used the weakness to add to our position.”

“Stock selection in Healthcare has been a value-add to performance over the past three years…perhaps some degree of mean reversion was inevitable, as returns lagged in the quarter. Individual underperformers were ICON and Coloplast, the latter being a relatively newer holding (purchased in 4Q25).”
ICON - March 2026
“ ICON Plc (ICLR) was weak in the quarter along with its broader peer group as AI-driven concerns had investors questioning the longer-term impacts on the CRO business model. ICON also announced an internal accounting investigation largely around its revenue recognition practices (affecting <2% of annual revenues over a three-year period) which further weighed on the stock. We believe both concerns are more than reflected in the current price and we used the weakness in the stock to add to our position.”

“Icon Public Limited Company ($ICLR) is a global contract drug manufacturing company we’ve followed for some time but was always too well priced to own.
