Quantum Cyber (QUCY) on Thursday rejected a recent short-seller report, calling it “materially misleading” and “self-interested.”
The company said the report distorted its capital structure, business strategy, and technology partnerships, and noted that the short-selling firm behind it was recently sued by another Nasdaq-listed company for $20 million for similar actions.
White Diamond Research raised concerns about the company, which pivoted from pharmaceuticals to defense this year, in late June.

While reviewing its SEC filings, White Diamond found that Quantum Cyber chief executive David Lazar invested $6 million in the company for convertible equity representing 477 million shares.
“This could potentially trigger massive dilution for existing shareholders,” the firm said. “Current shareholders are in for a rude awakening if and when insiders, mainly David Lazar, decide to dump his hundreds of millions of shares.”
The firm also questioned the nature of the company’s business, whether it is in the quantum computing or cybersecurity space, and what connection its corporate name has with manufacturing drones and unmanned aerial systems, implying that it is trying to play with buzzwords.

Among other things, the firm wrote about the company’s recent drone partnership with BP United and highlighted that its partner's website was broken and blank.
Moreover, the recent decision to buy SpaceX shares as an asset, like Triller, was seen by the firm as a means to create a pump-and-dump opportunity for insiders. It noted that Triller had planned to buy SpaceX shares at a discount before its IPO, whereas Quantum Cyber has to buy them at face value.
“We think QUCY is a project created for insiders to dump hundreds of millions of shares that they received for much lower than the current market price. We believe there is little to no fundamental value in the company and its business segments,” the firm said.
