Intense Competition from Rivals and E-commerce: BJ's operates in a highly competitive retail market, facing direct competition from other wholesale clubs like Costco and Sam's Club, as well as traditional supermarkets, discount retailers, and rapidly growing e-commerce platforms. This intense competition can pressure pricing, reduce market share, and require significant investment in membership benefits and services to retain and attract customers.

Economic Downturn and Consumer Spending Habits: Economic downturns, high inflation, or reduced consumer discretionary spending can negatively impact BJ's sales and membership renewals. Consumers may reduce their spending on non-essential items, trade down to lower-priced goods, or curtail club memberships, directly affecting BJ's revenue and profitability.

Supply Chain Disruptions and Increased Costs: BJ's relies on a complex global supply chain. Disruptions due to natural disasters, geopolitical events, labor shortages, transportation issues, or supplier failures can lead to inventory shortages, increased procurement costs, and an inability to meet customer demand, impacting sales and margins.
