[Form 4] Data Storage Corporation Warrant Insider Trading Activity

Rhea-AI Filing Summary

Data Storage Corp. (DTST) filed a Form 4 showing insider activity by EVP, Director and 10 % owner Thomas Kempster on 08/04/2025.

• Options exercised: 16,666 shares at $2.00 and 9,804 shares at $1.96 (transaction code “M”).
• Total shares acquired: 26,470 common shares, paid in cash to the company.
• Post-exercise ownership: 865,582 DTST shares held directly.
• Derivative holdings remaining: 8,334 and 4,902 unexercised option shares.

No shares were sold in conjunction with the exercises, so Kempster’s equity stake increased. Because the purchases were made below prevailing market prices implied by the option grants, the filing may be interpreted as insider confidence, while the issuance of new shares adds a small amount of dilution.

Positive

• Insider buying: EVP/10 % owner purchased 26,470 shares, increasing direct stake to 865,582.
• No sales reported: Entire transaction was an acquisition, reinforcing confidence signal.

Negative

• Minor dilution: Issuance of 26,470 new shares slightly increases outstanding share count.

Insights

Securities Analyst

TL;DR: EVP exercised 26.5k options, boosting stake to 865k shares; generally positive insider signal.

Insider option exercises without simultaneous sales often reflect confidence in future share performance. Kempster now controls roughly 0.87 million shares, reinforcing his long-term alignment with shareholders. The exercised strike prices ($1.96–$2.00) are modest, suggesting the options were in-the-money. While the issuance is mildly dilutive, the 26,470 new shares represent a negligible fraction of DTST’s float, so balance-sheet impact is limited. Overall, the transaction is modestly positive for sentiment but not likely to move fundamentals.
