Lock‑up agreements on AMG Critical Materials and peers expire July 12, 2026

Effective July 12, 2026, the lock‑up agreements that capped the sale of certain ordinary shares for AMG Critical Materials N.V. and a slate of other issuers have expired. The removal of these restrictions opens the door for shareholders to trade the shares on the open market, a shift that analysts say may trigger heightened volatility and liquidity shifts.

Core developments across the affected issuers

According to a series of filings reported by marketscreener.com, the following securities are now unrestricted:

• Ordinary shares of AMG Critical Materials N.V. – the lock‑up ends on 12‑JUL‑2026.Source 1
• Class A ordinary shares of New Horizon Aircraft Ltd. – the same termination date.Source 2
• A shares of JiangXi Tianxin Pharmaceutical Co., Ltd. – also ending on 12‑JUL‑2026.Source 3
• Ordinary shares of BBSB International Limited – lock‑up expires on 12‑JUL‑2026.Source 4
• Shares of Star Plus Legend Holdings Limited – lock‑up concludes on 12‑JUL‑2026.Source 5
• 10,203,960 Class B ordinary shares of One and One Green Technologies, Inc. – lock‑up terminates on 12‑JUL‑2026.Source 6

All six announcements cite the identical end date, suggesting that the agreements were likely entered into at the time of each company’s initial public offering or a recent secondary offering, a common practice to protect early investors and underwriters.

Why it matters

A lock‑up period is a contractual clause that prevents insiders, early investors, and sometimes institutional holders from selling their shares for a predetermined span, typically 90 to 180 days after an IPO. The purpose is twofold: it stabilises the share price during the early trading window and assures the market that large blocks of stock will not flood the market immediately.

When the lock‑up lifts, the newly tradable shares can increase the float—the portion of a company’s equity available for public trading. An expanded float often improves liquidity, making it easier for buyers and sellers to execute trades without large price swings. However, the sudden availability of a sizeable share block can also prompt a short‑term sell‑off, especially if holders decide to lock in gains after a period of price appreciation.

For AMG Critical Materials N.V., a company focused on strategic minerals used in clean‑energy technologies, the timing is notable. The firm has been navigating a market that rewards green‑energy supply chains, and the release of locked shares could either bolster investor confidence by demonstrating confidence in the stock or pressure the price if a large contingent decides to cash out.

Similarly, New Horizon Aircraft Ltd., a developer of electric vertical‑takeoff and landing (eVTOL) aircraft, and JiangXi Tianxin Pharmaceutical, a Chinese pharmaceutical player, may see divergent outcomes. The aviation sector is currently buoyant with government incentives, while the pharmaceutical space is subject to regulatory cycles. The removal of trading constraints may amplify these sector‑specific dynamics.

Differing viewpoints and market reactions

Market observers generally agree that post‑lock‑up periods are a litmus test for investor sentiment. Some analysts caution that the “lock‑up cliff” can precipitate a wave of selling, especially if early investors were motivated by short‑term gains. Others argue that the modern IPO environment, with higher institutional participation, mitigates the classic sell‑off because large holders tend to have longer investment horizons.

In the case of One and One Green Technologies, Inc., the precise number of shares—10,203,960 Class B ordinary shares—has been highlighted in filings, underscoring the material size of the block that will now be free to trade. Industry commentators note that such a precise figure allows market participants to model potential supply‑side pressure more accurately.

While no company‑specific commentary has been published yet, the collective expiration of multiple lock‑ups on the same day has drawn attention from traders monitoring the broader market impact. Some traders view the synchronised expiry as a catalyst for a modest uptick in overall market volume, while others remain wary of sector‑specific volatility spikes.

What’s next for the newly unfrozen shares

Investors should watch several indicators in the weeks ahead:

• Trading volume: An immediate rise in daily volume for each of the six securities will signal how aggressively shareholders are exercising their newfound freedom.
• Price movement: Any pronounced price dip could suggest that a portion of the float is being sold, whereas stable or rising prices might indicate confidence among holders.
• Company guidance: Post‑lock‑up, firms often release updates on capital‑raising plans, strategic initiatives, or earnings forecasts to reassure the market.
• Analyst coverage: Updated research reports may incorporate the expanded float into valuation models, potentially adjusting target prices.

For AMG Critical Materials N.V., the next earnings release—scheduled for the fourth quarter of 2026—could provide a clearer picture of how the unlocked shares influence market perception. Similarly, New Horizon Aircraft Ltd. is expected to file a quarterly update on its eVTOL prototype testing, a development that may either absorb or amplify any post‑lock‑up price movement.

Overall, the simultaneous expiration of these lock‑up agreements marks a notable moment for a diverse set of companies, offering both risk and opportunity for market participants as the newly tradable shares enter the open market.
