short position financial

"Culper Research holds a short position in ADMA."

A short position is when an investor borrows shares and sells them now because they expect the stock’s price to fall, planning to buy the shares back later at a lower price and return them. It matters to investors because it can amplify gains if the bet is right but cause unlimited losses if the price rises; large short positions also affect market supply, signal negative sentiment, and can increase volatility, similar to many people betting against a team's chances.

(Nasdaq: ADMA) (“ADMA” or the “Company”), a U.S. based, end-to-end commercial biopharmaceutical company dedicated to manufacturing, marketing and developing specialty biologics, today addressed a report issued on March 24, 2026 by Culper Research (the “Short Report”), a firm that has published similarly negative “research reports” regarding public companies after taking short positions in the stock. The Short Report discloses that Culper Research holds a short position in ADMA. ADMA, and its Board of Directors takes seriously its obligations to fairly and accurately report its operating and financial results and make all public disclosures in accordance with the rules and regulations of the U.S. Securities and Exchange Commission and in accordance with the standards of U.S. GAAP. The Short Report, by contrast, appears premised on speculative assertions derived from unidentified and unreliable sources and contains numerous misleading, false and inaccurate statements. Despite the conjecture pervading the Short Report, ADMA is taking appropriate steps to review the assertions.
