HOND Stock Surges on Merger News

HCM II Acquisition Corp. (NASDAQ: HOND) – a blank-check SPAC – has seen its stock price jump dramatically in recent trading. On Oct. 13, HOND opened at $21.69, up from a prior close of $18.86, and closed around $21.21 on unusually high volume Marketbeat. The rally continued into Oct. 14–15: by the afternoon of Oct. 15 the stock was trading near $24.98 (a near-52-week high) Investing. Market observers note that volume has been surging (over 1 million shares traded on Oct. 13 Marketbeat), underscoring that many investors are positioning ahead of a key event. MarketBeat reported a 25% jump in trading volume on Oct. 14 as HOND jumped to $22.24 (from $21.00 the prior close) Marketbeat.

This breakout comes just days before a major vote: shareholders of HCM II will meet on Oct. 20, 2025 to approve the SPAC’s merger with Terrestrial Energy Businesswire Businesswire. The SEC recently declared the merger registration statement effective on Sept. 26 Businesswire, clearing the way for that vote. If the business combination is approved and closed, the new company (effectively Terrestrial Energy) plans to list on Nasdaq under the symbols “IMSR” (common stock) and “IMSRW” (warrants) Businesswire. In other words, an approval would directly turn HOND holders into shareholders of a publicly traded nuclear reactor firm.

SPAC Merger and Company Background

HCM II Acquisition is a special-purpose acquisition company – essentially a “blank check” vehicle that raised capital via IPO in 2024 with the sole purpose of merging with a target business Marketbeat. Its management, led by CEO Shawn Matthews, is focused on high-growth tech. The chosen target, Terrestrial Energy, is a Canadian clean-energy startup developing advanced nuclear reactors. Terrestrial’s flagship product is the IMSR (Integral Molten Salt Reactor), a small modular reactor designed to supply zero-carbon baseload power and high-temperature industrial heat. (Terrestrial emphasizes that IMSR plants use standard low-enriched uranium fuel and can scale to gigawatt levels while remaining inherently safe Globenewswire Businesswire.)

Terrestrial’s technology has been attracting positive attention. For example, on Sept. 10, 2025 Terrestrial announced that the U.S. Nuclear Regulatory Commission completed its safety evaluation of the IMSR design – the first time the NRC has approved the principal design criteria for a commercial molten-salt reactor Globenewswire. The NRC specifically validated the IMSR’s temperature-based inherent safety control mechanism for power regulation Globenewswire. These regulatory endorsements reduce a major technical risk. Separately, Terrestrial was just selected for the Department of Energy’s Fuel Line Pilot Program, bolstering confidence that its standard-assay low-enriched uranium (SALEU) fuel strategy can support large deployments Globenewswire. As Terrestrial CEO Simon Irish noted, these “dual recognitions” by the DOE highlight confidence in both the reactor design and its fuel/supply-chain strategy Globenewswire.

Both CEOs have been upbeat. In recent press releases, Irish called the S-4 effectiveness a “key transaction milestone” and touted their IMSR as a “transformative” solution to global energy demand Businesswire. HCM II’s Shawn Matthews likewise praised Terrestrial’s IMSR: “We view Terrestrial Energy’s IMSR technology as a transformative solution for the world’s growing industrial energy needs, delivering safe, reliable, and cost-effective power,” he said Businesswire. This nuclear technology promises to extend nuclear energy into new markets – beyond just electricity – by providing high-temperature heat for data centers, manufacturing, and more Businesswire.

Market and Analyst Reaction

Investors have responded strongly. Institutions are taking note: according to MarketBeat, JPMorgan added about $552,000 worth of HOND in Q2 Marketbeat, and hedge funds like North Capital raised their holdings by two-thirds in Q3 Marketbeat. The flurry of buying helped propel HOND higher. On the sell-side, the focus is on the looming vote: traders generally expect shareholders to approve the deal, so HOND is effectively tracking Terrestrial’s implied valuation (around $1.3 billion in enterprise value) ahead of Oct. 20.

Analyst sentiment is mixed. Market data shows Weiss Ratings reaffirmed a “Sell (D-)” rating on HOND shares in early October Marketbeat. On the other hand, independent analysts are enthusiastic about the nuclear angle. Seeking Alpha contributor Sarfatti initiated coverage on Oct. 14 with a Buy recommendation for HOND, pointing to Terrestrial’s strong leadership, recent regulatory wins, and the large addressable market for next-gen reactors Seekingalpha. He wrote that Terrestrial “stands out” among modular reactor developers thanks to “positive regulatory momentum, strong leadership, and technological advantages” Seekingalpha.

At least one analyst blog is very bullish: Financhill reports that virtually all key technical indicators for HOND are in buy mode Financhill Financhill. For example, HOND’s 50-day moving average is only about $13.63, far below the current price, and shorter-term momentum oscillators (RSI, MACD, etc.) are showing strong upward trends Financhill Financhill. In plain terms, HOND has been in a clear uptrend with little resistance overhead, suggesting room to run if the merger goes through. However, traders also caution that stocks rising this quickly can see pullbacks on profit-taking, especially after the Oct. 20 meeting.

Technical Outlook and Investor Takeaways

From a technical standpoint, HOND looks extended. The stock is near a 52-week high ($26.00) Investing, and its relative strength index (RSI) is in overbought territory. Many chartists would interpret this as a sign the stock has momentum – but also that short-term profit-taking could occur. Financhill’s data shows all short-term simple moving averages (8-day, 20-day) are bullish buys Financhill. On the downside, if the merger vote were somehow delayed or derailed, HOND could retrace sharply (as many SPACs do when deals falter).

On the fundamental side, HOND’s only business is this one merger. It has no revenues or operations of its own Financhill. Its value comes from the combined company: if the merger closes, HOND shareholders will own Terrestrial’s business. In that sense, HOND is more like a disguised stock pick in the nuclear space. The fundamentals of Terrestrial will then matter. Right now, Terrestrial touts an innovative reactor, key regulatory approvals, and DOE backing – all positives. But the market for commercial small modular reactors is still speculative and capital-intensive.

Bottom Line: HOND’s recent rally reflects excitement about the nuclear merger narrative. With the SEC green light and an October 20 shareholder vote looming Businesswire Businesswire, investors are betting on a smooth approval. If approved, HOND will convert into a public Terrestrial Energy (Nasdaq: IMSR), giving retail investors exposure to advanced nuclear power. Even so, some experts remain cautious: ratings firms still view HOND skeptically Marketbeat and remind investors that SPAC deals carry uncertainty. Technical indicators suggest the stock has momentum Financhill Financhill, but also that it’s already run high into key resistance. In the coming days, watch the Oct. 20 vote outcome and any new guidance. A positive vote could push HOND even higher, while a ‘no’ vote would send it back toward its trust-fund redemption price (~$10).

The shares have fallen about 40% from their September peak. Burry indicated he's wary of larger tech names-Meta Platforms, Alphabet, and Microsoft-but argued their core businesses should weather AI-driven headwinds. His Oracle call adds to his reputation for spotting overvalued assets, though the outcome remains uncertain.
