Baron Emerging Markets Fund disclosed three new equity positions in its Q1 2026 letter — Vista Energy, Prio S.A., and The Japan Steel Works — marking the first explicit move by a marquee EM vehicle into what the firm calls "global security/supply chain diversification." The fund manages $4.2 billion in assets and sits in the top quartile of EM equity funds by five-year alpha. The additions came during a quarter when the MSCI EM Index shed 2.3% while Baron's portfolio returned 1.1%, according to preliminary disclosures.
Vista Energy is an Argentine oil and gas producer with 78% of production in the Vaca Muerta shale formation. Prio S.A. operates offshore Brazilian fields with proven reserves exceeding 420 million barrels oil-equivalent. The Japan Steel Works manufactures forging presses and reactor components used in LNG infrastructure and nuclear supply chains. Baron did not disclose position sizes, but the timing aligns with a $340 million reduction in Chinese internet and consumer holdings over the same period, per the fund's commentary.
The thesis is straightforward. Supply chain rewiring favors countries with permitting speed, energy independence, or alliance optionality. Argentina's new mining and energy framework went live in December 2025, offering 30-year tax stability for projects exceeding $200 million. Brazil's pre-salt oil output hit a record 3.2 million barrels per day in February, and Petrobras announced it would reduce its offshore stake sales, tightening supply for independent operators like Prio. Japan Steel Works holds a 60% global share in clad steel plates for hydrogen storage, a bottleneck component as Japan and South Korea each tender 15+ GW of hydrogen infrastructure by 2028. Baron is buying into suppliers before the infrastructure spend prints.
This is the second EM fund in eight weeks to name "supply chain security" as a portfolio driver. Lazard EM Equity disclosed similar language in late March, though it initiated in Indian contract manufacturers rather than energy and materials. The pattern matters because EM allocators historically rotate *away* from commodity plays during U.S. rate uncertainty. The 10-year Treasury sits at 4.18%, yet Baron and Lazard are both adding to sectors with high capital intensity and long breakeven cycles. That signals conviction that commodity and infrastructure re-shoring will outlast the next Fed pivot.
Operators should watch Baron's Q2 commentary for whether these three positions expand or whether this was a one-quarter thematic test. The Japan Steel Works reports earnings May 8; guidance on order backlogs will clarify whether hydrogen infrastructure tenders are converting to signed contracts. Vista Energy's April production report will show whether Vaca Muerta drilling continues at the 22-rig pace sustained since January. Prio's offshore output data comes monthly; any acquisition talk will surface in the May 15 analyst call, especially if Petrobras follows through on its offshore pullback.
Baron has now named four new positions in the past six months, all outside China, all in sectors with tangible output. The fund's largest detractor last quarter was a Chinese e-commerce platform down 34%. The portfolio is being rebuilt around things you can touch.
