The MLP Investment Case & Outlook as AMLP Turns 15

The Alerian MLP ETF (AMLP) marks its 15-year anniversary, underscoring the enduring investment case for energy infrastructure MLPs, as tracked by the Alerian MLP Infrastructure Index (AMZI). MLPs have historically delivered compelling income, averaging a 7.40% yield, alongside real asset exposure and diversification benefits through low correlation with other asset classes. The sector's outlook remains constructive, driven by expectations for continued distribution growth, robust free cash flow generation, and healthier balance sheets, with current valuations (8.8x forward EV/EBITDA) remaining attractive relative to their 10-year average.

Analysis

The Alerian MLP Infrastructure Index (AMZI), which underlies the Alerian MLP ETF (AMLP), demonstrates a resilient 15-year track record centered on high income, real asset exposure, and portfolio diversification. Historically, the index has provided an average yield of 7.40% and has shown a low correlation to both bonds and the S&P 500, a characteristic that distinguishes it from other real asset classes like REITs. The current investment outlook for the MLP space is constructive, supported by a significant improvement in fundamentals compared to a decade ago. Companies within the index are now characterized by robust free cash flow generation and reduced leverage, enabling a shift from dilutive equity issuance to shareholder-friendly capital returns. This is evidenced by the fact that over 70% of the AMZI's constituents by weight have active buyback authorizations, and there have been no distribution cuts among its members in over four years. Despite strong performance, valuations remain attractive; the AMZI trades at a forward EV/EBITDA multiple of 8.8x based on 2026 estimates, comfortably below its 10-year average of 9.7x, while its current yield is above the 15-year average.

Key Decisions for Investors

• Investors seeking income and portfolio diversification should consider the MLP sector, as its current yield exceeds the 15-year average of 7.40% and it maintains a low correlation to traditional asset classes like equities and bonds.
• The sector's improved fundamentals, characterized by strong free cash flow generation, reduced leverage, and a focus on shareholder returns through buybacks and consistent distribution growth, support a constructive investment thesis.
• With the AMZI index trading at a forward EV/EBITDA of 8.8x against a 10-year average of 9.7x, the current valuation presents a potentially favorable entry point for investors, as it does not appear stretched despite recent strong performance.
