CALC Form 4: CBO lifts stake to 1.0M shares with new purchase
Rhea-AI Filing Summary
CalciMedica, Inc. (CALC) – Form 4 filed 10 Jul 2025
Chief Business Officer, Director and 10% owner Eric W. Roberts reported an open-market purchase of 5,000 common shares on 09 Jul 2025 at $1.6047 per share. After the transaction, he beneficially owns roughly 1,002,410 CALC shares distributed across direct holdings (164,706 shares), several Roth/Traditional IRAs and three Valence Investments SPVs, the largest of which holds 356,989 shares. No derivative securities were transacted in this filing.
The acquisition marginally increases Roberts’ stake by about 0.5% and may signal incremental confidence, though the dollar value is modest relative to his existing position.
Positive
- Insider purchase: 5,000 CALC shares bought on 07/09/2025 at $1.6047, indicating continued executive confidence.
- Large existing stake: Post-transaction beneficial ownership totals about 1,002,410 shares, aligning executive incentives with shareholders.
- No sales or derivative exercises reported, removing immediate dilution or profit-taking concerns.
Negative
- Immaterial size: The 5,000-share buy equals roughly 0.5% of Roberts’ holdings and less than $9 k in value, limiting signaling power.
- Single-participant action: No concurrent insider purchases by other executives were disclosed, reducing breadth of bullish signal.
Insights
TL;DR: Modest insider buy; confidence signal limited by small size.
Roberts’ 5,000-share purchase confirms continued alignment between management and shareholders, yet represents only ~0.5% of his 1.0 million-share stake. Absence of selling and lack of derivative activity keep the filing neutral-to-slightly positive, but the low transaction value (<$9 k) is unlikely to alter market perception or near-term valuation. Overall impact: limited.
