Aristotle Capital Management, LLC, an investment management company, released its "Value Equity Fund" Q2 2026 investor letter. A copy of the letter can be downloaded here. The Fund delivered a 4.32% total return in Q2 2026, underperforming the 13.87% gain for the Russell 1000 Value Index and the 15.20% return for the S&P 500, while its 1.99% year-to-date return also lagged the Russell 1000 Value Index's 16.26% and the S&P 500's 10.21%. The Fund attributed the performance gap largely to limited exposure to the AI infrastructure spending boom, noting that the U.S. has about 4,000 existing data centers and nearly 3,000 more planned or under construction, while AI-related demand has created bottlenecks in processors and memory. The letter highlighted the scale of the cycle, with industry cash flows in key AI hardware areas rising sharply, while the Russell 1000 Value Index's top 10 contributors gained an average 182% year to date and accounted for 9.29 percentage points of the index's 16.23% return. Looking ahead, the fund expects investors to eventually reassess the sustainability of current AI infrastructure earnings and valuations.

Aristotle Value Equity Fund stated the following regarding Atmos Energy Corporation (NYSE:ATO) in its Q2 2026 investor letter:

We first invested in Atmos Energy Corporation (NYSE:ATO), the largest fully regulated natural gas-only utility in the U.S., in the first quarter of 2022. We were attracted to the company's strong balance sheet, constructive regulatory environment across its service territories and significant opportunity to invest in infrastructure modernization projects. During our holding period, Atmos benefited from ongoing system replacement programs, population growth in its key markets and supportive rate mechanisms that allowed it to earn attractive returns on invested capital. While we continue to view Atmos as a high-quality business, we believe many of the catalysts identified at purchase have either been realized or are well underway. Looking ahead, we expect the company's growth plan to require a significantly higher level of equity capital than in prior investment cycles. As a result, we elected to exit our position and redeploy the proceeds into Autodesk, which we believe offers a more compelling investment opportunity (Click Here To Read Letter In Detail).
