New York, May 26, 2026, 18:01 (EDT)
- Terra Innovatum closed Nasdaq trading at $6.25, 20 cents lower than its last finish.
- The company needs to either get back in compliance or send in a plan about its late SEC filings by June 15.
- Nuclear stocks traded up, while Terra slipped, pointing to a company issue for Terra.
Terra Innovatum Global N.V. shares gave up ground on Tuesday after part of last week’s rally, as the stock reacted to a Nasdaq compliance notice over delayed financial filings.
The nuclear microreactor developer listed on Nasdaq ended the after-hours session at $6.25, slipping 20 cents from its previous close. Shares had been as high as $6.93 earlier. About 472,000 shares traded.
Nasdaq flagged Terra in a deficiency notice on May 19 for missing its first-quarter 2026 Form 10-Q and still being late on the 2025 Form 10-K, according to a U.S. Securities and Exchange Commission filing. That matters now because the company is facing time pressure. The 10-Q is a standard quarterly update, while the 10-K gives investors the full view on annual results, risks, and accounts.
Terra has a deadline of June 15 to either get back in compliance or send a plan to Nasdaq, according to the filing. If Nasdaq signs off on the plan, the company could get an exception through Oct. 12, 2026. Trading of the shares is not affected for now by the notice.
The stock dropped after the extended U.S. holiday weekend. Nasdaq’s 2026 calendar shows Memorial Day falls on May 25, when the market was closed. Tuesday marked the first full session since the break.
Terra said May 22 it plans to file its 2025 10-K by June 15 and, after that, will submit the first-quarter 10-Q “as promptly as practicable.” CFO Katherine Williams said the filing delay was “not related to any underlying financial performance or operational issues,” citing post-combination reporting and technical accounting matters instead.

That’s the point for the stock. Terra wrapped up a SPAC deal with GSR III Acquisition Corp. in October, then started trading on Nasdaq as NKLR. The late filings all come during its first year after going public.
Nasdaq Composite and S&P 500 both finished at record highs Tuesday, Reuters said, with the Nasdaq up 1.19%. The decline came as the rest of the tape moved higher.
Shares of other listed nuclear developers moved higher. Oklo traded up at $68.70, NuScale Power hit $12.22, and Nano Nuclear Energy was at $29.07, market data showed. Oklo got a lift after it was tapped by the U.S. government for talks to use surplus plutonium as reactor fuel.
The industry still looks favorable, but it isn’t straightforward. Reuters said Tuesday the U.S. Nuclear Regulatory Commission is working to speed up signoffs for small modular and microreactor models. Amy Roma, partner at Orrick, said the regulator might have “seen what you’re doing” even before a commercial filing comes in, which can cut some extra steps. Reuters
Terra is working on U.S. NRC licensing for its SOLO micro-modular reactor and has set up a supply and manufacturing network with third parties, targeting commercial rollout by 2028. SOLO is a small nuclear reactor that generates power in one-megawatt increments.
The risk is the reporting schedule could slip. If Terra’s compliance plan comes in late or gets rejected, the stock faces a continued listing overhang. Trading is still happening, but investors have little new financial data as Terra sorts out its delayed 10-K and 10-Q.
NKLR is moving mostly on filings instead of news about its reactor right now. The June 15 date is the next key event.
