Factors Affecting Performance [Text Block]

How did the Fund Perform?

The Kingsbarn Dividend Opportunity ETF (the “Fund”) returned -4.73% for the six-month period of 11/1/2025 to 04/30/2026. The Fund underperformed its broad-based benchmark, the S&P 500® index, which returned 6.03% over the same period. Additionally, the Fund underperformed its secondary indices, the MVIS US Mortgage REITs Index and the MVIS US Business Development Companies Index, which returned 9.51% and -1.45%, respectively, during the same period.

What Factors Influenced Performance?

During March and April 2026, the Fund’s investment universe of income-oriented specialty finance sectors, including Mortgage REITs and Business Development Companies, was negatively impacted by heightened geopolitical conflict, rising energy prices, higher inflation expectations, higher long-term interest rates, and increased interest-rate volatility. Additionally, as a more concentrated portfolio than the two secondary indices against which the Fund is benchmarked, the market volatility negatively impacted the performance of the Mortgage REITs and Business Development Companies held by the Fund to a greater extent than realized by the comparable indices.

Market Review

The Fund remained confident that a concentrated portfolio of Agency Residential Mortgage REITs, along with select Commercial Mortgage REITs and Business Development Companies, would deliver attractive total returns as market volatility normalized and investment spreads remained favorable for levered Residential Mortgage-Backed Security investors. The Fund also believed that select Commercial Mortgage REITs continued to trade at meaningful discounts to the value of their underlying assets and represented attractive risk-adjusted return opportunities if commercial real estate markets continued to stabilize.
