Montauk Renewables, Inc. MNTK

What this company does

Montauk Renewables, Inc. develops, owns, and operates RNG projects that supply renewable fuel into the transportation and electrical power sectors. It has established a currently operating portfolio of eleven RNG and two Renewable Electricity projects and development projects, built through self-development, partnerships, and acquisitions, that span seven states. The revenues Montauk receives from selling renewable energy consist of two main components: the commodity value of the natural gas or electricity generated, and revenues from the Environmental Attributes derived from the production of RNG and Renewable Electricity. It sells the RNG produced from its projects to counterparties under a variety of short-term and medium-term agreements, with tenures generally varying from three to five years. The Renewable Electricity produced at its biogas-to-electricity projects is sold under long-term contracts with terms ranging up to 18 years, excluding renewal periods, and a weighted average remaining tenure of 16 years based on 2025 electricity production. In January 2021, the company closed the initial public offering of its common stock on the Nasdaq Capital Market, with the shares traded under the symbol "MNTK," and its common stock is also secondarily listed on the Johannesburg Stock Exchange under the trading symbol "MKR."
