Why are they buying?

AI · discretionary · catalyst credible · documented

Insiders purchased shares on the open market shortly after the release of Harrow's first-quarter 2026 financial results, where management reaffirmed full-year revenue guidance and expressed strong confidence in product demand and commercial momentum.

CEO Mark L. Baum and President Andrew R. Boll, alongside directors Lauren P. Silvernail and Adrienne L. Graves, acquired shares between May 14 and May 18, 2026, following a Q1 earnings release that highlighted record prescription performance for VEVYE and robust year-over-year demand for IHEEZO and TRIESENCE.
