Listen to the news

TG Therapeutics (TGTX) has drawn fresh attention after recent trading left the share price at $52.95, with the move coming alongside mixed short term returns but notable gains over the past year.

For context, TG Therapeutics has a 1-day share price gain of 1.46% but is down 5.07% over the past week and 10.35% over the past 90 days. The year-to-date share price return of 80.84% and 3-year total shareholder return above 6x indicate that longer term momentum has been strong even as shorter term sentiment has cooled.

TG Therapeutics looks like a powerful growth story on recent numbers, yet the stock now trades around $52.95 after a sharp multi year run. Is that price still grounded in what investors actually get for the business today?

Most Popular Narrative: 24% Undervalued

On the most followed narrative, TG Therapeutics is framed as worth $69.71 per share, compared with the recent close at $52.95, which puts the focus squarely on whether BRIUMVI can support that gap through execution across multiple autoimmune indications.

The planned launch of subcutaneous BRIUMVI remains a key upcoming catalyst, as it targets the 35 to 40% of the anti CD20 multiple sclerosis market that is currently in self administered products where TG Therapeutics does not yet participate. This could materially affect future revenue and earnings. The fully enrolled Phase 3 program for subcutaneous BRIUMVI, supported by Phase 1 data indicating around 60% bioavailability and acceptable injection tolerability and guided toward a potential 2028 launch, could allow TG Therapeutics to participate in both infusion and self administered anti CD20 segments and affect top line growth and operating leverage.

See why 69 investors see TG Therapeutics as 24% undervalued.

Result: Fair Value of $69.71 (UNDERVALUED)

Still, the bullish TG Therapeutics story can crack if BRIUMVI spending keeps squeezing profits or if governance investigations deepen and distract management at key execution moments.
