[Form 4] CalciMedica, Inc. Insider Trading Activity

Rhea-AI Filing Summary

CalciMedica, Inc. (CALC) – Form 4 insider transaction by CFO Stephen Bardin

On 26 June 2025, Chief Financial Officer Stephen Bardin executed two reportable transactions:

• Open-market purchase: 2,000 shares of CALC common stock at a weighted-average price of $1.5025 (price range $1.45-$1.54). The shares are held indirectly by The Bardin Family Trust dated 4 June 2024.
• Employee stock option grant: 20,000 options with an exercise price of $1.53 per share, immediately exercisable and expiring 22 April 2035. The grant was approved by the Board on 23 April 2025 and became effective upon shareholder approval of the amended 2023 Equity Incentive Plan on 24 June 2025.

Post-transaction ownership

• Indirect: 3,000 shares (Bardin Family Trust)
• Direct: 40,000 shares
• Derivative: 20,000 stock options

The filing also corrects a prior Form 4 (3 June 2025) that had misclassified 1,000 trust-held shares as directly owned. No other financial metrics or operational updates were included.

Insights

Financial Analyst

TL;DR Small insider buy plus 20k option grant; marginal but positive alignment signal.

The CFO’s purchase—though modest in dollar terms (~$3k)—shows personal capital commitment at prices near CALC’s recent trading range. Insider buying typically signals management confidence, especially for clinical-stage biotechs where visibility is limited. The immediate-vest option award further links compensation to long-term equity performance following shareholder approval of the amended 2023 EIP. While the correction of prior share classification highlights administrative oversight, it does not affect economic exposure. Given the scale, the event is incrementally positive but not likely to move valuation absent broader catalysts.

Corporate Governance Expert

TL;DR Governance processes observed: shareholder-approved plan, prompt Section 16 reporting; minor filing correction noted.

The Board conditioned the option grant on shareholder approval, demonstrating procedural rigor. The Form 4 was filed within two business days, meeting Section 16 requirements. The clerical correction of 1,000 shares indicates attention to accuracy, albeit after an earlier mistake. Overall governance signals are sound; equity awards remain within typical biotech norms.
