At the end of 2014, there were a record 124 MLPs trading. By the end of 2015, that number had fallen to 121, and by the end of 2016 there were only 112. At the end of January 2017, there were 110 and, if all pending mergers are approved, another handful will disappear. The loss of over a dozen companies has begun to worry some investors.

While MLPs are generally insulated from moderate moves in commodity prices, the huge fall in the price of crude oil, combined with minimal recovery, has impacted the more commodity-sensitive MLPs. Many upstream MLPs declared bankruptcy over the past two years and are no longer trading on major exchanges.

Midstream MLPs may be more insulated from commodity price moves but they are not immune. As their customers struggled, and some contracts were not renewed, the fundamentals of midstream MLPs suffered. Negative investor sentiment across the entire energy sector further depressed prices, increasing the cost of equity for MLPs. As leverage ratios rose, so too did the cost of debt.

In order to lower their cost of capital so they could continue to pursue growth, many MLPs bought out a parent’s incentive distribution rights or merged with each other or a parent company. While the bankruptcies of the commodity-sensitive MLPs are indeed worrying, smarter combinations and capital structures will remove growth headwinds.

As MLPs continue to position themselves to pursue growth, 2017 is likely to see more merger and simplification announcements. The space may begin to barbell into a handful of mega-caps and many small- or micro-caps with the result that the largest companies will need to both compete for bids and cooperate when joint ventures are necessary. The smaller midstream companies must find and defend their niches and unique offerings.

With few MLP S-1s filed with the U.S. Securities and Exchange Commission, indicating plans to go public and create new companies, each company that remains trading can spend the next few years building its individual moat without competition from new entrants.

Consolidation is a natural part of many industries, particularly those which require significant upfront infrastructure investment. As such, the absolute number of MLPs should not be investors’ primary focus when considering the future of the space. More than whether a company is structured as a C corporation or an MLP, its existing footprints, cost of capital and availability of labor will determine how well it is positioned to participate in the buildout of North American energy infrastructure over the next several decades.
