Key Facts

Terrestrial Energy announced on October 27 that its board had authorized a program to repurchase up to $25 million of its common shares. The company said the purchases would be funded from available cash, but the authorization does not require it to buy any shares. The program expires on October 22, 2027, and the company retains the right to amend, suspend or terminate it at its discretion. The announcement sets a ceiling on the amount that could be allocated to purchases, not a commitment to spend the full amount. The timing and size of any purchases will also remain subject to management's decision, market and economic conditions, the share price, capital needs and legal requirements.

If management decides to proceed, purchases may be made in the open market, through privately negotiated transactions, block trades or other means. Options include a trading plan under Rule 10b5-1, according to the company's statement. Management will determine the timing, method, price and volume of purchases at its discretion, taking into account market and economic conditions and capital needs. The authorization therefore sets no schedule for purchases or target share price. The announcement also does not mean the company will make purchases, nor does the program guarantee direct support for the stock or a certain increase in earnings per share.

About 105.9 million shares were outstanding as of October 23, according to the company's filing; that figure includes shares issuable upon the exchange of exchangeable shares. The company's stock, listed under the ticker IMSR, closed at $2.94 on October 26, according to EL7 data. That closing price does not establish that the stock rose in response to the announcement, which came the following day. In its latest available financial results, the company said it ended the second quarter on June 30 with $283.4 million in cash and cash equivalents and investments. Its net loss was $9.4 million in the second quarter, compared with a $10.5 million loss in the first quarter.

The company used $6.4 million in cash for operating activities during the second quarter, down $1.5 million from the first quarter. It attributed the decrease mainly to differences in the timing of certain testing activities. The authorized buyback comes as the company continues its nuclear development and regulatory work, while its reported liquidity provides financial context for the decision. In the second quarter, the U.S. Nuclear Regulatory Commission approved the company's Preliminary Accident Analysis Methodology Report. The company also continued its TETRA and TIFIA projects in partnership with the U.S. Department of Energy.

As part of its expansion, the company signed land lease and research agreements with the Texas A&M University System for the use of 77 acres at the RELLIS site. It said the agreements allow it to secure control of the site and complete its characterization and environmental assessment. On September 10, it announced that the graphite report submitted to the Nuclear Regulatory Commission was the second of at least three technical reports it expects to submit during the year. On September 21, it announced its support for an Ameresco power generation project at the U.S. Army's Aberdeen Proving Ground, which combines natural gas with advanced nuclear power. It then appointed David Williams chief commercial officer on October 20, with the chief executive saying his role includes developing the portfolio of commercial projects with partners.

The company estimates cumulative lifetime revenue from a single IMSR plant at about $2.7 billion, up from a previous estimate of $2.1 billion, with an estimated blended gross margin of 33%. These are company estimates, not realized revenue. The company says its work with regulators, suppliers and partners is aimed at deploying a fleet of its plants at multiple U.S. sites during the 2030s. That goal places the buyback program within a broader development phase encompassing the site, regulatory reports and commercial partnerships. The program itself remains optional and expires on October 22, 2027, unless the company amends, suspends or terminates it earlier.
