FuelCell Energy Inc (NASDAQ:FCEL) shares are surging on Tuesday as investors digest data centers account for nearly 90% of the company's sales pipeline. Here’s what investors need to know.

What Is FuelCell Energy’s Latest Catalyst?

FuelCell Energy late Monday said data centers represent nearly 90% of its pipeline after reporting fiscal second-quarter results that missed expectations, with an adjusted loss of 53 cents per share on revenue of $35.589 million. The company also said its second-quarter sales pipeline reached 4 gigawatts, up 267% from the first quarter, and it introduced a standardized 12.5 MW "Energy Block" aimed at faster time-to-power for AI and data center projects.

FuelCell Energy's quarter also included a $42.6 million noncash impairment tied to Groton Project equipment upgrades, contributing to a wider gross loss of $12.9 million. Service revenue fell to $4.2 million from $8.1 million and generation revenue decreased to $8.7 million from $12.1 million as repairs weighed on output.

With the market in premarket trading, FCEL's move higher suggests traders are weighing the data-center narrative against the near-term execution issues highlighted by the miss.

FCEL Stock: Critical Moving Averages To Watch

From a trend perspective, FCEL is still in a longer-term uptrend (up 107.50% over the past 12 months) and remains well above its 50-day, 100-day, and 200-day moving averages, but it's trading 16.4% below its 20-day SMA ($20.94), which points to a cooling phase after the recent run. The 20-day SMA remains above the 50-day SMA ($13.98), and the 50-day SMA is above the 200-day SMA ($9.22), keeping the broader moving-average structure bullish.

Momentum is the near-term question: MACD is below its signal line and the histogram is negative, which typically means upside pressure is fading unless buyers can reassert control. In plain English, MACD compares faster and slower trend signals, and being below the signal line often shows the recent push higher is losing steam.

  • Key Resistance: $20.94 — the 20-day SMA is the nearest overhead trend level after the pullback
  • Key Support: $13.98 — the 50-day SMA is a key trend "line in the sand" after the stock's sharp 12-month run

What Is FuelCell Energy’s Business Model?

FuelCell Energy Inc is a clean energy technology company that develops, designs, produces and services high-temperature fuel cells used for clean electric power generation. Its molten carbonate fuel cell systems generate electricity electrochemically with ultra low emissions and high efficiency, and the company often acts as a full solutions provider across design, manufacturing, installation, and long-term maintenance.

That business model matters for the current setup because management is leaning into data centers and AI-related demand for reliable, on-site power in grid-constrained markets, including a standardized 12.5 MW block product. The company operates across the U.S., South Korea, Europe and Canada, with the U.S. as its largest revenue source, so execution on large projects and service/generation uptime can heavily influence quarterly results.
