What this transaction means for investors
Jimenez wasn’t the only SVP conducting insider transactions near the beginning of 2026. On Dec. 15, 2025, SVP & CBO Pepin Ronald acquired 19,333 shares by exercising two previously granted stock options. One option allowed him to purchase 8,333 shares at a price of $9.02, while the other provided him with 11,000 shares at an exercise price of $2.78. The total value of the acquisitions was $105,744.
Then on Jan. 2, 2026, Martin Samuel Bates, SVP and CFO, also acquired shares by exercising an option. He acquired 4,817 shares at a price of $10.38, worth $50,000. It’s unclear why both Ronald and Bates waited years to exercise their options, even though they reached their strike prices years earlier.
Celldex Therapeutics is struggling as a stock, but it did experience a positive year in gains in 2025, albeit slightly, after two consecutive years of declining share prices. The company’s financials are deteriorating, with it reporting zero revenue in its Q3 FY2025 report, compared to the $3.19 million it had reported a year prior.
The antibody developer has also experienced six consecutive quarters of worsening net loss, culminating in a net loss of -$67 million in Q3 2025. It’s unclear what the intent was behind the recent transactions of the three Celldex SVPs, but regardless, the stock is not an ideal buy right now.
