Contributors included a large overweight in The Williams Companies, a U.S.-based natural gas pipeline operator, which rose materially on expansion projects and improved operational efficiencies to better monetize growing natural gas demand. Stock selection in electric utilities also contributed, led by an overweight investment in Entergy Corporation. The company secured an expanded agreement with Meta for a Louisiana data center campus, increasing investment in power generation and grid infrastructure, while insulating other customers from the related costs. Stock selection in marine ports further contributed, driven by an overweight investment in International Container Terminal Services. The stock outperformed as earnings have consistently exceeded analysts' expectations, while the company continues to pursue accretive mergers and acquisitions.&lt;/p&gt;&lt;p style="text-align: left"&gt;Stock selection in the gas distribution sector detracted from relative performance, with an overweight investment in China-based ENN Energy Holdings declining after a planned takeover failed to materialize and lower-than-expected earnings and macroeconomic headwinds added pressure. An allocation to environmental services also detracted, with Cleanaway Waste Management delivering disappointing guidance. Security selection in the communications sector detracted, largely due to a lack of exposure to satellite operator Viasat. The company recently benefited from rising satellite enthusiasm following SpaceX's initial public offering, as well as the potential spinoff of its defense business.&lt;/p&gt;

Contributors included a large overweight in The Williams Companies, a U.S.-based natural gas pipeline operator, which rose materially on expansion projects and improved operational efficiencies to better monetize growing natural gas demand. Stock selection in electric utilities also contributed, led by an overweight investment in Entergy Corporation. The company secured an expanded agreement with Meta for a Louisiana data center campus, increasing investment in power generation and grid infrastructure, while insulating other customers from the related costs. Stock selection in marine ports further contributed, driven by an overweight investment in International Container Terminal Services. The stock outperformed as earnings have consistently exceeded analysts' expectations, while the company continues to pursue accretive mergers and acquisitions.&lt;/p&gt;&lt;p style="text-align: left"&gt;Stock selection in the gas distribution sector detracted from relative performance, with an overweight investment in China-based ENN Energy Holdings declining after a planned takeover failed to materialize and lower-than-expected earnings and macroeconomic headwinds added pressure. An allocation to environmental services also detracted, with Cleanaway Waste Management delivering disappointing guidance. Security selection in the communications sector detracted, largely due to a lack of exposure to satellite operator Viasat. The company recently benefited from rising satellite enthusiasm following SpaceX's initial public offering, as well as the potential spinoff of its defense business.&lt;/p&gt;

Contributors included a large overweight in The Williams Companies, a U.S.-based natural gas pipeline operator, which rose materially on expansion projects and improved operational efficiencies to better monetize growing natural gas demand. Stock selection in electric utilities also contributed, led by an overweight investment in Entergy Corporation. The company secured an expanded agreement with Meta for a Louisiana data center campus, increasing investment in power generation and grid infrastructure, while insulating other customers from the related costs. Stock selection in marine ports further contributed, driven by an overweight investment in International Container Terminal Services. The stock outperformed as earnings have consistently exceeded analysts' expectations, while the company continues to pursue accretive mergers and acquisitions.&lt;/p&gt;&lt;p style="text-align: left"&gt;Stock selection in the gas distribution sector detracted from relative performance, with an overweight investment in China-based ENN Energy Holdings declining after a planned takeover failed to materialize and lower-than-expected earnings and macroeconomic headwinds added pressure. An allocation to environmental services also detracted, with Cleanaway Waste Management delivering disappointing guidance. Security selection in the communications sector detracted, largely due to a lack of exposure to satellite operator Viasat. The company recently benefited from rising satellite enthusiasm following SpaceX's initial public offering, as well as the potential spinoff of its defense business.&lt;/p&gt;

Contributors included a large overweight in The Williams Companies, a U.S.-based natural gas pipeline operator, which rose materially on expansion projects and improved operational efficiencies to better monetize growing natural gas demand. Stock selection in electric utilities also contributed, led by an overweight investment in Entergy Corporation. The company secured an expanded agreement with Meta for a Louisiana data center campus, increasing investment in power generation and grid infrastructure, while insulating other customers from the related costs. Stock selection in marine ports further contributed, driven by an overweight investment in International Container Terminal Services. The stock outperformed as earnings have consistently exceeded analysts' expectations, while the company continues to pursue accretive mergers and acquisitions.&lt;/p&gt;&lt;p style="text-align: left"&gt;Stock selection in the gas distribution sector detracted from relative performance, with an overweight investment in China-based ENN Energy Holdings declining after a planned takeover failed to materialize and lower-than-expected earnings and macroeconomic headwinds added pressure. An allocation to environmental services also detracted, with Cleanaway Waste Management delivering disappointing guidance. Security selection in the communications sector detracted, largely due to a lack of exposure to satellite operator Viasat. The company recently benefited from rising satellite enthusiasm following SpaceX's initial public offering, as well as the potential spinoff of its defense business.&lt;/p&gt;

Contributors included a large overweight in The Williams Companies, a U.S.-based natural gas pipeline operator, which rose materially on expansion projects and improved operational efficiencies to better monetize growing natural gas demand. Stock selection in electric utilities also contributed, led by an overweight investment in Entergy Corporation. The company secured an expanded agreement with Meta for a Louisiana data center campus, increasing investment in power generation and grid infrastructure, while insulating other customers from the related costs. Stock selection in marine ports further contributed, driven by an overweight investment in International Container Terminal Services. The stock outperformed as earnings have consistently exceeded analysts' expectations, while the company continues to pursue accretive mergers and acquisitions.&lt;/p&gt;&lt;p style="text-align: left"&gt;Stock selection in the gas distribution sector detracted from relative performance, with an overweight investment in China-based ENN Energy Holdings declining after a planned takeover failed to materialize and lower-than-expected earnings and macroeconomic headwinds added pressure. An allocation to environmental services also detracted, with Cleanaway Waste Management delivering disappointing guidance. Security selection in the communications sector detracted, largely due to a lack of exposure to satellite operator Viasat. The company recently benefited from rising satellite enthusiasm following SpaceX's initial public offering, as well as the potential spinoff of its defense business.&lt;/p&gt;
