Product Sales

In 2023, United States Lime & Minerals Inc. dispatched nearly all its products within the United States, primarily targeting states like Arkansas, Colorado, and Texas, among others. Sales efforts are chiefly managed by ten sales personnel who engage with existing and potential customers through orders based primarily on purchase agreements. The customer base comprises approximately 650 entities, ensuring a diversified risk with no single customer commanding over 10% of sales. Notably, the demand for lime and limestone products is sensitive to changes in sales volume, pricing, and operational costs.

Seasonality

Sales tend to exhibit seasonal trends, with peak shipments and revenue typically occurring in the second and third quarters of the fiscal year. Adverse weather conditions can negatively impact the demand for lime and limestone products, especially for construction-related applications.
