Factors Affecting Performance [Text Block]  
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
Since the Fund’s launch on November 20, 2025, through the period ended May 31, 2026, the Fund returned +33.39%, outperforming its benchmark, the S&P 500 Total Return Index, which returned +16.64%. The Fund primarily invested in U.S. equities across various sectors, with a focus on companies that are the beneficiaries of long-term secular trends currently unfolding in the global economy, including digitalization, electrification, reindustrialization and national security. This led to the Fund holding overweight positions relative to the benchmark in the Materials, Industrials and Energy sectors.
TOP PERFORMANCE CONTRIBUTORS
The Fund’s performance benefited from exposure to companies within the Materials, Energy, and Technology sectors. Within Materials, the Fund’s exposure to Newmont Corporation and Freeport-McMoRan reflected an investment thesis centered on gold as a store of value in an inflationary environment and on copper demand tied to data center and electrical infrastructure buildout; both companies contributed as gold and copper prices rose accordingly. The Fund’s Energy holdings, led by Golar LNG and Targa Resources, were
positioned to benefit from global energy supply constraints, and delivered strong operating results during the Period. Within Technology, the Fund’s focus on the semiconductor industry reflected the view that artificial intelligence infrastructure buildout would drive demand for data storage and manufacturing capacity; Seagate Technology and Lam Research, direct beneficiaries of this demand, saw their share prices increase significantly
TOP PERFORMANCE DETRACTORS
The factors weighing on performance were primarily driven by select stocks within the Financial and Industrial sectors. Arthur J. Gallagher & Co. sold off on fears that artificial intelligence could disrupt the insurance brokerage industry, though the Fund’s position reflected the company’s consistent revenue growth and high client retention. Blackstone Inc., one of the leading providers of private/alternative investments, came under pressure on concerns that private credit was facing an uptick in defaults; the Fund’s exposure, however, reflected Blackstone’s diversified alternative investment business lines. Parker Hannifin, a large industrial company, saw its stock consolidate after a period of relatively strong performance. The Fund’s position reflected the company’s specialization in motion and control systems used in reindustrialization-related markets.

WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?

Since the Fund’s launch on June 25, 2025, through the period ended May 31, 2026, the Fund returned +79.48%, outperforming its benchmark, the S&P 500 Total Return Index, which returned +25.81%. The Fund primarily invested in U.S. equities across various sectors, with a focus on companies that are the beneficiaries of long term- secular trends currently unfolding in the global economy. The Fund seeks to identify well-positioned and undervalued companies across small, mid, and large market capitalization ranges.
TOP PERFORMANCE CONTRIBUTORS
The Fund’s performance benefited from exposure to companies within the Materials, Technology and Industrial sectors. Within Materials, the Fund’s exposure to Newmont Corporation and Freeport-McMoRan reflected an investment thesis centered on gold as a store of value in an inflationary environment and on copper demand tied to data center and electrical infrastructure buildout; both companies contributed as gold and copper prices rose accordingly. The Fund's Industrial holdings, led by GE Vernova and Quanta Services, reflected a focus on infrastructure tied to power generation and grid capacity; GE Vernova benefited as a leading provider of gas turbines, while Quanta Services benefited from its role as a leading specialty infrastructure contractor supporting electricity, natural
gas, and communications networks. Kratos Defense and Security Solutions was a large contributor as well, benefiting from its position as a drone manufacturer. Within Technology, the Fund's focus on the semiconductor industry reflected the view that artificial intelligence infrastructure buildout would drive demand for data storage and manufacturing capacity; Micron Technology, Western Digital, and Lam Research were beneficiaries of this demand.
TOP PERFORMANCE DETRACTORS
The factors weighing on performance were primarily driven by select stocks within the Energy, Financial and Healthcare sectors. The Fund's sale of Cheniere Energy, based on the view that shares were fully valued, preceded a rise in energy prices tied to escalating conflict in the Middle East, resulting in relative underperformance versus the sector. Blackstone Inc., one of the leading providers of private/alternative investments, came under pressure on concerns that private credit was facing an uptick in defaults; the Fund’s exposure, however, reflected Blackstone’s diversified alternative investment business lines. Regeneron Pharmaceuticals, a fully integrated biotechnology company, posted positive performance during the Period but lagged the index on a relative basis.
