Standard Nuclear (NYSE:STDN) reported second-quarter revenue of $4.7 million, up from $0.6 million a year earlier, as the company completed its first commercial deliveries of TRISO nuclear fuel and expanded its contracted backlog. The company, which began trading on the New York Stock Exchange in July, also outlined plans to add manufacturing capacity and advance a joint venture production site expected to begin operations in 2027.
“This quarter, we shipped our first commercial fuel core load,” President and Chief Executive Officer Kurt Terrani said on the company’s first earnings call as a public company. “We signed contracts on the back of it, and the demand behind those contracts moved toward us on every measure we track.”
Commercial Fuel Delivery and Backlog Growth
During the second quarter, Standard Nuclear shipped a 50-kilogram batch of HALEU TRISO fuel to Radiant Industries for the Kaleidos demonstration-unit microreactor. The fuel was delivered to the Department of Energy’s DOME facility at Idaho National Laboratory. Shortly after the quarter ended, the company delivered the remaining fuel required for a full commercial reactor core load for Radiant’s first microreactor.
The company said the shipment represented the first complete reactor core of commercially produced TRISO fuel supplied by an independent U.S. manufacturer. The core is intended to support a full-power, full-temperature demonstration using fuel from Standard Nuclear’s Oak Ridge production line.
Standard Nuclear’s total contract backlog rose to $241.5 million as of June 30, from $91.3 million at March 31. Funded backlog increased to $61.9 million from $8.2 million over the same period.
In August, the company entered a fuel supply agreement with Antares Nuclear that includes a firm commitment for one metric ton of HALEU TRISO fuel and customer options for up to an additional seven metric tons over several years. Giving effect to that agreement, funded backlog increased to $119.3 million, while total contract backlog reached $576.9 million.
Chief Financial Officer Kevin Harrill said the June 30 backlog consisted of:
- $61.9 million in funded backlog;
- $156.5 million in purchase options under executed contracts; and
- $23.1 million in unfunded backlog.
Following the Antares agreement, purchase options increased to $443.5 million and unfunded backlog declined to $14.1 million, Harrill said. Qualified pipeline, which is not included in backlog, stood at approximately $696.3 million as of the earnings call.
Harrill said revenue from fuel-development agreements is generally recognized over the course of work performed, while revenue under fuel supply or offtake agreements is generally recognized upon delivery, subject to the specific terms of each contract.
Revenue, Margins and Expenses
Product revenue accounted for $3.1 million of second-quarter revenue, reflecting TRISO fuel deliveries under a fuel supply agreement. The remaining $1.6 million came from service revenue tied to fuel-development contracts and projects with U.S. government agencies.
Cost of revenue rose to $1.6 million from $1.2 million a year earlier, while gross profit totaled $3.2 million. Gross margin was approximately 67% during the quarter.
Standard Nuclear reported a net loss of $3.4 million, or $0.12 per share, compared with a net loss of $1.6 million, or $0.06 per share, in the prior-year quarter. The company said its sequential net loss narrowed from $7.7 million in the first quarter, primarily due to its first commercial product revenue.
General and administrative expenses increased to $5.5 million from $1 million a year earlier. Harrill attributed the increase to the build-out of public-company infrastructure, including $1.6 million in share-based compensation, $1.5 million in third-party consulting fees related to the public-company transition, and $1.4 million in payroll and benefits.
Research and development expense was $2 million, primarily supporting process engineering, qualification, licensing and authorization work for the company’s new Tennessee and Idaho production sites. Standard Nuclear said it does not expect the cost of its public-company infrastructure to rise substantially as production scales.
Capacity Additions and Regulatory Pathways
Construction is substantially complete at Standard Nuclear’s SN-TN facility in Oak Ridge, Tennessee, and SN-ID facility in Idaho. Each site is designed to begin with up to one metric ton of annual TRISO production capacity and potentially expand to 2.5 metric tons annually, for combined capacity of up to five metric tons.
The Department of Energy has approved the preliminary documented safety analysis for both facilities, and manufacturing-module commissioning is underway. The company is targeting authorization to operate the facilities in the fourth quarter of 2026.
Subject to authorization, Standard Nuclear expects its original Oak Ridge production line, SN0, along with the two new facilities, to provide up to 2.5 metric tons of annual throughput by year-end. The company’s longer-term plan contemplates capacity approaching 40 metric tons annually by the end of the decade, although Terrani said the company would add capacity in response to contracted demand rather than build speculatively.
Standard Nuclear also acquired land and an existing Oak Ridge building for $5.5 million in cash during July. The company said its Oak Ridge holdings now total about 57 acres.
Separately, the Nuclear Regulatory Commission approved a license amendment for Framatome’s Richland, Washington, facility that permits enrichment up to just under 10% uranium-235 and authorizes TRISO particle fuel fabrication. Standard Nuclear expects its joint venture with Framatome to begin production at Richland in 2027, initially at approximately one metric ton annually, with potential expansion to two metric tons.
Balance Sheet and Outlook
Standard Nuclear ended the second quarter with $102.2 million in cash and cash equivalents and no debt. Its July initial public offering of 10 million Class A shares at $15 per share generated approximately $137.7 million in net proceeds, bringing pro forma cash to about $240 million.
The company said its Tennessee and Idaho facilities were fully funded before the IPO. Deferred revenue increased to $4 million at June 30 from $1.1 million at year-end 2025, which Harrill said reflected customer deposits and milestone payments used to reserve production capacity.
Management did not provide financial guidance. Its stated operational milestones include targeted fourth-quarter authorization for SN-TN and SN-ID and the planned 2027 start of production at the Framatome joint venture’s Richland facility.
