Energy Vault's Japan Ambition Meets Insider Sales and Oil Price Volatility

Energy Vault signs binding deal for 850 MW of energy storage in Japan, targeting $180M+ annual EBITDA, as CFO executes planned stock sale and sector faces headwinds.

Energy Vault Holdings, Inc. is making a bold move into the Japanese energy storage market, even as its leadership team executes planned stock sales and broader sector headwinds create a complex backdrop for investors. The company's shares gained roughly 8% on Thursday, trading around €2.82, though they remain down approximately 32% for the year.

The core driver of the recent optimism is a major expansion into Asia. Energy Vault has signed a binding agreement for a project portfolio in Japan with a total capacity of 850 megawatts (MW). This portfolio is split into two phases: 350 MW are in an advanced stage of development, with an additional 500 MW in earlier phases. Construction on the first facilities is slated to begin in the second half of 2027, targeting full operational readiness by 2028.

Japan represents a strategic growth market, driven by its goal of achieving carbon neutrality by 2050 and concurrent systemic bottlenecks in its power grid. Analysts project the Japanese battery energy storage system (BESS) market to grow at an annual rate exceeding 50%. Upon completion, Energy Vault's management anticipates the Japanese projects will contribute over $180 million in annual EBITDA within 12 to 36 months after handover.

This expansion boosts the company's global pipeline to over 1 gigawatt, which includes other projects like a 175-MW endeavor in Texas. To navigate local permitting and land acquisition, Energy Vault is integrating a team of on-the-ground experts in Japan.

Concurrent with this growth news, the company's Chief Financial Officer, Michael Thomas Beer, sold a portion of his holdings. On April 6, Beer sold 65,000 shares at a price of $3.18 per share. This transaction was not discretionary; it was executed under a pre-arranged trading plan (Rule 10b5-1) established in December 2025. In a related move, the CFO also exercised options for 50,000 shares at a significantly lower strike price.

Despite these sales, Beer retains a substantial stake of over one million shares in the company. The sale, representing a reduction of nearly six percent of his position, is largely viewed by the market as a routine portfolio adjustment rather than a signal of declining confidence.

The broader market environment for energy storage specialists has turned volatile. A potential two-week ceasefire between the U.S. and Iran concerning oil transit through the Strait of Hormuz recently triggered a sharp drop in crude prices, marking the most significant single-day decline since April 2020. Falling energy prices can temporarily dampen the economic urgency for efficiency solutions, putting pressure on the valuation of infrastructure and storage projects.

In response to such market shifts, Energy Vault is emphasizing its "Own & Operate" strategy, aiming to generate stable, high-margin recurring revenue through direct asset ownership and operation.

The path to consistent profitability, however, still shows some unevenness. The company's fourth-quarter 2025 results highlighted a discrepancy, with revenue of $153.3 million but conflicting data on earnings per share; some sources indicated a small profit while others reported a significant loss. Investors are now focused on whether the strategic shift toward recurring revenue models will deliver the promised stability to the company's financials.
