Insider Buying Amid a Turbulent Stock Price

LIQTECH International’s latest 4‑form filing shows Bleichroeder LP, acting as registered investment adviser for the 21 April Fund and 21 April Fund, LP, buying 700,000 shares on June 5 and an additional 3 million shares on June 8. The purchases were made at $1.00 each—well above the closing price of $0.89 on June 7—and at a time when the stock has already fallen 31 % in the week and 65 % for the month. The deal is part of a public offering that will raise $20 million and cancel $3 million in promissory notes, a move that could improve liquidity but also dilutes existing shareholders.

What Investors Should Take Note Of

The timing and size of these transactions suggest that Bleichroeder’s funds are betting on a rebound. The company’s price‑to‑earnings ratio remains negative and the stock has struggled to stay above its 52‑week low of $0.77. Yet the fund’s investment adviser is willing to commit 4.3 million shares—roughly 16 % of the outstanding equity—at a price that is 12 % above the day‑close. This could signal confidence in the company’s debt‑repayment plan and its technology niche in ceramic silicon carbide filters, a sector that is gaining traction as diesel engines move toward stricter emissions standards.

Bleichroeder LP: A Pattern of Opportunistic Buying

Historically, Bleichroeder has purchased and then sold warrants for common stock in March 2025, buying 531,250 shares and selling the same number in the same filing. That short‑lived position hints at a strategy of quick, high‑confidence trades rather than long‑term holding. The new purchases are larger in scale and aligned with the company’s public offering, indicating a willingness to ride the volatility of a small‑cap clean‑tech company in exchange for a potentially higher upside once the debt is serviced and the stock recovers.

Insider Activity Across the Board

Other insiders have also been active. CEO Chen Fei sold 67,860 shares at $1.49 on January 3, 2026, while CFO/COO David Kowalczyk bought 94,368 shares at $0.00 (likely a grant) and later sold 5,589 shares at $1.49. The mix of sales and purchases among executives could reflect a balance between personal liquidity needs and confidence in the company’s future. However, the net effect of these insider transactions remains neutral, leaving the market to weigh the significance of Bleichroeder’s larger buy.

Implications for the Future

The combined effect of debt cancellation, a cash‑generating public offering, and sizeable insider buying may create a short‑term rally if the market interprets the moves as a sign that the company is on a stable financial footing. Yet the steep decline in share price, negative earnings multiple, and the company’s need to maintain operational cash flows mean that any rally could be fleeting. For investors, the key will be to monitor the company’s ability to convert its clean‑tech patents into revenue streams and to see whether the stock can climb back toward its 52‑week high of $3.35.
