Vertical Farming Bankruptcies: What Went Wrong?

For years, vertical farming was pitched as the ultimate solution to global food security. Investors poured billions into startups that promised to grow produce in warehouses without soil, sunlight, or pesticides. However, 2023 proved to be a disastrous year for the sector. Industry leaders like AeroFarms, AppHarvest, and Kalera filed for Chapter 11 bankruptcy protection, leaving investors and consumers wondering if the technology is viable or if the economic model is fundamentally broken.

The Collapse of the Industry Giants

The vertical farming sector did not just see a slowdown; it experienced a rapid implosion of its most prominent players. These companies raised massive amounts of venture capital and went public through Special Purpose Acquisition Companies (SPACs), only to run out of cash a few years later.

AeroFarms

Based in Newark, New Jersey, AeroFarms was considered the poster child of the industry. They utilized aeroponics to mist roots with nutrients. Despite raising over $238 million and operating a high-profile 136,000-square-foot facility in Danville, Virginia, the company filed for Chapter 11 bankruptcy in June 2023. The primary issue was that their revenue growth could not keep pace with the massive overhead required to run their facilities. While AeroFarms emerged from bankruptcy in late 2023 with a new CEO, Molly Montgomery, the restructuring wiped out significant equity value.

AppHarvest

AppHarvest operated massive high-tech greenhouses in Kentucky rather than windowless warehouses, yet they faced similar financial pressures. Backed by high-profile board members like Martha Stewart, they went public at a valuation over $1 billion. By July 2023, they filed for bankruptcy. Their struggle involved operational issues, including labor turnover and lower-than-expected yields on their tomato crops. Their facilities were eventually sold to Equilibrium Capital and Bosch Growers to pay off creditors.

Kalera and Fifth Season

Kalera, a vertical farming company based in Florida, filed for Chapter 11 in April 2023 after losing access to credit. Similarly, Pittsburgh-based Fifth Season abruptly shut down in late 2022 despite having its salad kits in 1,200 supermarkets like Kroger and Whole Foods. The trend was clear: solvency was impossible once interest rates rose and cheap capital dried up.

The Unit Economics Problem

The core reason these companies failed is simple economics. It costs significantly more to grow a head of lettuce in a climate-controlled warehouse than it does to grow it in a field in California or Arizona.

The Energy Bill

The promise of vertical farming is that it uses 95% less water than traditional agriculture. However, it trades water for electricity. Replacing the sun with LEDs is expensive. Even more costly is the HVAC (heating, ventilation, and air conditioning) required. Plants release moisture as they grow. In a closed warehouse, this humidity must be mechanically removed to prevent mold. This process is incredibly energy-intensive. When global energy prices spiked in 2022, the operating margins for these farms evaporated.

CAPEX Intensity

Building a vertical farm is more like building a semiconductor factory than a traditional farm. It requires sensors, robotics, specialized lighting, and racking systems. This high Capital Expenditure (CAPEX) meant that startups burned through their funding just building the facility. Once operational, they had heavy debt loads to service. When the Federal Reserve raised interest rates, the cost of this debt became unmanageable for companies like AppHarvest.

The "Salad Trap"

Another critical failure point was the limited variety of crops. Almost every major vertical farm focused on leafy greens, herbs, and microgreens.

Fast Growth Cycle: Lettuce grows quickly (often in 30 days), allowing for multiple harvests per year.
Low Calorie, Low Price: Unfortunately, lettuce is a low-calorie crop with a relatively low price ceiling. You can only charge so much for a box of arugula before consumers refuse to buy it.
Lack of Diversification: Growing high-calorie crops like wheat, corn, or soy indoors is economically impossible. Even “fruiting crops” like strawberries and tomatoes are difficult because they require pollination and take longer to grow, occupying valuable rack space for longer periods.

Because every startup targeted the same premium salad market, they eventually saturated the shelf space at high-end grocery stores, leading to fierce competition for a small segment of customers.

Is there a Future for Vertical Farming?

Despite the bankruptcies, the industry is not dead. It is undergoing a necessary correction. The surviving companies are shifting strategies to ensure long-term viability.

Shift to the Middle East

Investment is moving away from the US and Europe toward regions where food security is a genuine existential threat. Countries like Saudi Arabia and the UAE import up to 90% of their food. They also have abundant solar energy to offset electricity costs. AeroFarms, for example, opened a research center in Abu Dhabi, and the Saudi Public Investment Fund has partnered with AeroFarms for future projects.

Genetics and Breeding

Companies are realizing they cannot use standard seeds for indoor farming. Startup Ohalo (founded by the co-founder of Impossible Foods) is using gene editing to create plant varieties specifically designed for indoor environments. These plants might be shorter (to fit more racks) or have different light requirements, potentially changing the math on profitability.

The Walmart Effect

Some massive retailers are still betting on the tech. Walmart has invested heavily in Plenty, a vertical farming startup based in San Francisco. Plenty is moving beyond just greens and is working on scaling strawberry production. By securing a dedicated buyer like Walmart, Plenty bypasses the marketing and distribution costs that crushed smaller competitors.

Conclusion

The first wave of vertical farming failed because it tried to operate like a software company, prioritizing rapid growth and “move fast and break things” over agricultural fundamentals. The bankruptcies of AeroFarms and AppHarvest served as a reality check. The future of the industry lies not in replacing all traditional farming, but in filling specific niches—specifically in harsh climates or for high-value crops—where the massive energy costs can be justified by the lack of local alternatives.

Frequently Asked Questions

Why did AeroFarms go bankrupt? AeroFarms filed for Chapter 11 bankruptcy due to a combination of high energy costs, expensive debt servicing, and revenue that did not grow fast enough to cover the operational costs of their high-tech facilities. They have since emerged from bankruptcy with new leadership.

Are vertical farms bad for the environment? It depends on the energy source. While they use 90-95% less water and no pesticides, their carbon footprint can be significantly higher than traditional farming if the electricity used to power the LEDs and climate control comes from fossil fuels.

What happened to AppHarvest? AppHarvest filed for bankruptcy in 2023. Their assets, including their massive greenhouses in Kentucky, were sold to creditors and other agricultural firms like Equilibrium Capital.

Can vertical farms grow anything other than lettuce? Technically, yes. However, economically, it is very difficult. Fruiting crops like tomatoes, peppers, and strawberries require more energy, space, and time to grow, making them harder to sell at a profit compared to fast-growing leafy greens.

Who are the surviving vertical farming companies? Major surviving players include Plenty (backed by Walmart), Bowery Farming, and Oishii (known for high-end strawberries). However, even these companies have slowed expansion to focus on profitability.
