Economic Downturn and Demand Volatility: NN Inc.'s financial performance is highly sensitive to the cyclical nature of its primary end markets, including industrial, automotive, and aerospace, which can experience significant downturns leading to reduced customer orders and revenue.

Supply Chain Interruptions and Cost Increases: Disruptions in the global supply chain, including raw material shortages, transportation delays, and increased material costs, could adversely affect NN Inc.'s production schedules, increase operating expenses, and impact its ability to meet customer demand.

Customer and Market Concentration: A significant portion of NN Inc.'s revenue may depend on a limited number of large customers or specific market segments, making the company vulnerable to the loss of a key customer, reduced demand from such customers, or downturns in those specific markets.
