Energy Vault Holdings (NYSE: NRGV) has raised its full-year sales guidance for FY2026, signaling stronger-than-expected demand or execution in its energy storage business. The company increased the midpoint of its revenue range significantly, positioning the lower bound of its new forecast above the consensus analyst estimate.

The updated guidance sets the expected sales range at $270.000 million to $310.000 million for the fiscal year ending in 2026. This represents a substantial upward revision from the previous outlook of $225.000 million to $300.000 million. The move reflects a shift in management's expectations regarding order conversion, project timelines, or pricing power within its gravity-based energy storage solutions.

Guidance vs. Estimate

The revised lower bound of $270.000 million now sits comfortably above the market estimate of $252.440 million. This suggests that Energy Vault Holdings anticipates delivering revenue that will beat current analyst projections by a meaningful margin, assuming performance aligns with the new floor of the guidance range.

What the Numbers Show

The widening of the upper end of the guidance range from $300.000 million to $310.000 million, combined with the significant lift in the lower bound, indicates reduced downside risk and improved visibility into future cash flows. By raising the floor by $45.000 million, the company is effectively communicating that it expects to generate substantially more revenue than previously disclosed, while also capturing upside potential that was not fully priced into the prior ceiling.

Energy Vault Holdings reported second-quarter earnings per share (EPS) of $(0.18), meeting the analyst consensus estimate exactly. The company also posted quarterly sales of $17.369 million, surpassing the $14.143 million estimate by 22.81 percent. This revenue figure represents a 104.05 percent year-over-year increase from $8.512 million in the prior-year period. The strong performance was driven by progress in battery energy storage systems projects in Australia and expanding commercial activity in Switzerland.

Despite the beat on revenue estimates, the per-share loss improved by 18.18 percent compared to the $(0.22) loss recorded in the same period last year. This marks a significant narrowing of losses from the previously reported $(0.15) figure, aligning with broader market expectations for the quarter. The total GAAP net loss for the quarter stood at $29.7 million, an improvement from the $34.9 million net loss in the prior-year period. GAAP gross profit rose 114 percent year-over-year to $5.4 million, resulting in a GAAP gross margin of 31.0%, an expansion of 140 basis points from 29.6% previously. Adjusted gross margin, which excludes non-cash depreciation and amortization, reached 38.6%, up 900 basis points year-over-year.

The company’s contract backlog expanded significantly, growing by $650 million sequentially to reach approximately $2 billion as of August 10, 2026. This represents a 107 percent year-over-year increase, largely attributed to growth in the AI compute infrastructure segment. This substantial backlog prompted management to raise full-year 2026 revenue guidance to $270-$310 million from the previous range of $225-$300 million. Approximately 60 percent of the backlog consists of long-term, annual recurring revenue from owned energy infrastructure assets.

Strategic developments in AI infrastructure contributed heavily to the quarter’s outlook. Energy Vault announced a strategic agreement to deploy 1.25 GW of integrated power infrastructure with a leading power generation EPC for a hyperscaler AI data center in Texas. This deal is expected to generate near-term revenue of $500-$600 million through the end of 2027. Additionally, the company broke ground on its Snyder, Texas AI Campus for Crusoe, targeting commercial operation of the initial 8 MW phase in the first half of 2027. In Japan, Energy Vault completed the acquisition of an 850 MW BESS development portfolio in May 2026.

What the Numbers Show

The divergence between GAAP and adjusted metrics highlights the impact of non-cash charges on profitability. While adjusted gross margins expanded sharply to 38.6%, indicating improving unit economics, the GAAP net loss remains substantial at $29.7 million due to stock-based compensation and depreciation costs. The widening adjusted EBITDA loss from $13.6 million to $17.0 million year-over-year suggests that operating expenses are rising faster than operational leverage can offset them during this phase of global expansion. Investors should monitor whether the high-margin backlog conversion can accelerate sufficiently to narrow the path to profitability.
