Annual Meeting of Stockholders regulatory

"On May 29, 2026, Energy Vault Holdings, Inc. held its Annual Meeting of Stockholders."

broker non-votes regulatory

"Stephanie Unwin | 96,797,315 | 791,040 | 30,415,781 Broker Non-Votes"

Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.

independent registered public accounting firm financial

"Ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2026"

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.

Emerging growth company regulatory

"Emerging growth company"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.
