TG Therapeutics (TGTX) is back in focus after its Q2 2026 earnings update, which combined higher revenue and raised full year guidance with lower net income and earnings per share.

The raised 2026 guidance and focus on BRIUMVI come after a sharp short term pullback, with a 7 day share price return of down 6.7% and 30 day share price return of down 10.1%. TG Therapeutics still shows strong momentum over longer periods, with a year to date share price return of 70.4% and a 3 year total shareholder return of well over 4x.
