Data Storage Corp (DTST) director tender sale and share corrections

Rhea-AI Filing Summary

Data Storage Corp director and 10% owner Harold J. Schwartz reported significant share sales and ownership corrections. On January 14, 2026, he disposed of 888,376 shares of common stock at $5.20 per share in a sale to the company under an issuer tender offer exempt under Rule 16b-3, leaving him with 28,471 shares held directly.
