NET Power Lawsuit Deadline Looms: Investors Face Critical June 17 Deadline Amid Cost Overruns and Leadership Turmoil

Investors holding losses exceeding $100,000 in shares of NET Power Inc. (NYSE: NPWR) are under a legal microscope as the deadline to join a high-stakes securities class action lawsuit rapidly approaches. The case, Luciani v. Net Power Inc., accuses the company of systematically misleading markets about the viability of its flagship Project Permian—a project now mired in cost overruns, delays, and leadership instability. With shares of NPWR plummeting 31% following revelations of its struggles, the June 17, 2025, lead plaintiff deadline marks a pivotal moment for investors seeking to hold executives accountable.

The Project Permian Paradox: Cost and Timeline Catastrophes

At the heart of the lawsuit is Project Permian, a $1.7–2.0 billion utility-scale power plant designed to demonstrate NET Power’s breakthrough carbon capture technology. Originally projected to cost $1.1 billion and complete by late 2027, the project has since faced cascading setbacks. Supply chain bottlenecks and “site-specific challenges”—a euphemism for unforeseen engineering hurdles—pushed the completion date to no earlier than 2029.

The March 10, 2025, announcement of cost overruns triggered an immediate 31% drop in NPWR’s stock, from $6.89 to $4.75. A subsequent April 15, 2025, disclosure of leadership departures—including the COO and CFO—further eroded investor confidence, amplifying doubts about the company’s ability to manage its most critical project.

The Legal Battle: Misstatements or Unavoidable Setbacks?

The lawsuit alleges that NET Power and its executives violated federal securities laws by omitting critical risks and downplaying Project Permian’s challenges. Key claims include:
- Cost Mismanagement: Despite early warnings in November 2023—when the project’s timeline was first delayed—the company allegedly continued to present a rosier-than-real financial picture.
- Leadership Gaps: The abrupt departure of senior executives in April 2025, amid mounting operational pressures, raised red flags about governance.
- Artificially Inflated Valuation: The lawsuit asserts that these misstatements artificially inflated NPWR’s stock price during the June 9, 2023–March 7, 2025, class period, ultimately leaving investors with unsustainable losses.

Navigating the Legal Landscape: What Investors Need to Know

For affected investors, the June 17, 2025, deadline is non-negotiable. Those seeking to serve as lead plaintiff must file motions by this date to direct the lawsuit—a role that comes with significant responsibility, including selecting legal counsel. Even without this designation, investors can still participate in potential recoveries by registering with the case, but failure to act by June 17 may bar them from future claims.

The stakes are substantial. According to the lawsuit, the drop in NPWR’s stock after the March 10 disclosures alone wiped out over $1 billion in market capitalization. Historical data underscores the volatility: between June 2023 and March 2025, NPWR’s stock fluctuated between $5 and $12, hitting a peak of $14.30 in late 2023 before the first delay was disclosed.

Conclusion: A Crossroads for NPWR Investors

The June 17 deadline is more than a procedural milestone—it’s a reckoning for investors who trusted NET Power’s vision. The lawsuit’s allegations, if proven, could reshape perceptions of the company’s credibility and operational competence. With Project Permian’s costs nearly doubling and its timeline stretching into 2029, the question remains: Is this a case of honest setbacks in an ambitious project, or a pattern of corporate negligence?

The data tells a stark story. Shares have lost over 60% of their value since the project’s initial delays were disclosed in late 2023, and the March 2025 crash erased gains made over years of hype around carbon capture innovation. For investors with losses exceeding six figures, joining the lawsuit isn’t just about financial recovery—it’s about demanding transparency in an industry where groundbreaking technology often collides with brutal business realities.

Time is running out. As of June 17, 2025, the door to legal recourse will shut. For those still on the sidelines, the message is clear: Act now—or risk losing your voice in this critical case.
