The Company had no vendors that represented 10% or more of total purchases or payables for the years ended December 31, 2018 and 2017.

The Company’s revenue, profitability and future rate of growth are substantially dependent on prevailing prices for petroleum-based products. Historically, the energy markets have been very volatile, and there can be no assurance that these prices will not be subject to wide fluctuations in the future. A substantial or extended decline in such prices could have a material adverse effect on the Company’s financial position, results of operations, cash flows, and access to capital and on the quantities of petroleum-based products that the Company can economically produce.

Business commitment:

On June 5, 2016, Vertex Energy and Penthol C.V. (“Penthol”) of the Netherlands aka Penthol LLC (a Penthol subsidiary in the United States) reached an agreement for Vertex Energy to act as Penthol’s exclusive agent to provide marketing, sales, and logistical duties of Group III base oil from the United Arab Emirates to the United States. The start-up date was July 25, 2016, with a 5 year term through 2021 and the product will ship via truck, rail and barge.

Litigation:

The Company, in its normal course of business, is involved in various other claims and legal action. In the opinion of management, the outcome of these claims and actions will not have a material adverse impact upon the financial position of the Company. We are currently party to or have recently resolved, the following material litigation proceedings:
