TG Therapeutics has delivered a strong share price run over the past three years, yet the stock still screens as undervalued on earnings-based multiples and only a mixed verdict on the broader valuation checks.

• Over the past three years, TG Therapeutics has returned 184.5% to shareholders, which puts extra focus on whether the current valuation leaves enough room for error.
• Future revenue growth from its existing treatments can support the current price. However, execution risks around competition and ongoing development spend may limit how much investors are willing to pay for that growth.
• The company scores 4 out of 6 on our valuation checks, which points to a mixed picture rather than a clear bargain or clear overvaluation. You can see the detail of that score at 4 out of 6.

The issue now is whether TG Therapeutics' recent gains and current price around US$56.04 still offer an appealing entry point on valuation grounds.

Is TG Therapeutics Still Cheap on Earnings?

The P/E ratio is a useful cross check for TG Therapeutics because the company is now generating positive earnings that can anchor the multiple. At the current share price, TG Therapeutics trades on a P/E of about 17.2x, which is very close to the broader biotech industry average of 16.9x and below the peer group average of 22.2x.

On Simply Wall St’s fair P/E estimate of around 24.1x, which takes into account factors such as the company’s growth profile, margins, scale and risk, TG Therapeutics screens at a discount to what investors might typically pay for similar earnings. The gap between the current 17.2x and the fair 24.1x suggests the market is placing a lower multiple on the stock than this framework implies.

Overall, TG Therapeutics appears undervalued on an earnings multiple basis when compared with its tailored fair P/E estimate.

Bull case: 32% undervalued

Bear case: 180% overvalued

"The heavy reliance on BRIUMVI for revenue, combined with a narrow commercial portfolio and slow pipeline progression, leaves TG Therapeutics extremely exposed to competitive threats from established branded IV and newer subcutaneous options, which may lead to market share losses and declining top-line revenues as the anti-CD20 class matures..."

The Bottom Line

For TG Therapeutics, the key takeaway is that the stock still screens as undervalued on earnings multiples, but the broader checks point to a more balanced picture rather than a clear mispricing. The crux is whether revenue and margin progress from the existing portfolio, particularly BRIUMVI, can be delivered with enough consistency to convince the market to pay closer to that tailored P/E level. What matters most from here is whether execution keeps pace with expectations, or whether competitive and concentration risks end up justifying the current discount as a value trap rather than an opportunity.
