FDA approval puts Viridian Therapeutics into commercial spotlight

The recent FDA approval of Lumvoa for Thyroid Eye Disease puts Viridian Therapeutics (VRDN) into the commercial arena, shifting investor focus toward launch execution, early prescribing trends, and the size of its initial market opportunity.

Viridian Therapeutics has seen momentum pick up around the Lumvoa decision, with a 1-month share price return of 17.7% and a 3-month gain of 21.2%. However, the stock is still down 21.5% year to date, while the 3-year total shareholder return of 92.7% points to a much stronger longer-term journey as sentiment has shifted with each regulatory milestone.

Viridian Therapeutics just moved into prime time, yet the share price still trails both analyst targets and some intrinsic value estimates. Where does a fair entry really fall after this FDA approval jump?

Most Popular Narrative: 34% Undervalued

On the narrative view, Viridian Therapeutics screens as materially cheaper than its implied fair value of $36.75, compared with the last close at $24.09. This puts the focus squarely on how much of the thyroid eye disease opportunity is already embedded in expectations.

The key execution swing factor is whether Viridian can convert the current roughly $2b TED IGF-1R opportunity, with 6,000 to 7,000 patients treated annually and single-digit penetration, into broader adoption of its shorter-course IV and planned subcutaneous regimens.

Result: Fair Value of $36.75 (UNDERVALUED)

Still, Viridian Therapeutics relies on analysts’ steep revenue and margin assumptions, and any reset in those forecasts or the lofty 75x implied P/E could quickly challenge this undervalued story.

Another View: Viridian Therapeutics Looks Expensive On Sales

There is a very different picture when you look at Viridian Therapeutics through its P/S ratio instead of fair value models. The shares trade on 38.4x sales, compared with 10.7x for the US Biotechs industry and 8.7x for peers, while the fair ratio sits at just 0.1x. That gap places more of the valuation risk on execution. How comfortable are you paying a premium sales multiple for a business that still reports losses?
