Final answer:
Sam Antar pointed out increasing inventory turnover trends as a red flag at Green Mountain Coffee Roasters, indicating potential sales and inventory management issues.
Step-by-step explanation:
Sam Antar identified increasing inventory turnover trends as a warning sign at Green Mountain Coffee Roasters. This particular red flag suggests that the company may not be selling its inventory as quickly as before, which can indicate problems such as overestimation of demand or poor sales performance. When inventory grows faster than sales, it means products are not being sold as anticipated, leading to excess stock that ties up capital and may require liquidation at discounted prices, ultimately affecting the company's profitability.
Furthermore, excessive inventory growth compared to revenue can imply that a company is inflating its sales and earnings, which is a significant issue. A change in leadership can also be an indicator of potential problems, as it may disrupt operation continuity or entail a shift in corporate strategy, but this was not one of the specific warning signs highlighted by Antar in relation to Green Mountain Coffee Roasters.
