Shares of Beyond Meat (BYND) fell 5.80% in after-hours trading on Tuesday, despite earlier gains and positive news about expanded distribution with Walmart. The plant-based meat company, which had seen a dramatic surge in its stock price over the past few trading sessions, faced a sharp reversal in the extended trading hours.

Earlier in the day, Beyond Meat announced plans to increase the availability of select products at over 2,000 Walmart stores nationwide. This expansion included the introduction of the new Beyond Burger 6-Pack, a value offering aimed at price-conscious consumers. The news initially drove the stock up by over 140% during regular trading hours, continuing a streak of gains that had seen the stock rise from below $1 to over $3 in just a few days.

However, the after-hours plunge suggests that investors may be reassessing the company's prospects or taking profits after the recent surge. The stock's volatility in recent days has been attributed to increased attention from retail investors and potential short-covering, reminiscent of meme stock rallies. Despite the expanded distribution deal with Walmart, Beyond Meat continues to face challenges, including declining revenue and soft demand for its products. The company is set to report its third-quarter 2025 financial results on November 4, which may provide more clarity on its financial health and future outlook.
