IDEAYA Biosciences (IDYA) Could Be 38% Undervalued On Its Pipeline Narrative

Simply Wall St · 1d ago

IDEAYA Biosciences (IDYA) has drawn fresh attention after recent share performance moved out of step with its longer term record, prompting investors to reassess what the current US$32.85 price reflects.

Short term momentum has cooled for IDEAYA Biosciences, with the share price falling 2.95% over the last day and 12.93% over the past month, even as the 1 year total shareholder return of 12.27% and 5 year total shareholder return of 43.32% point to a much stronger longer term story.

Bulls see the recent pullback as noise against IDEAYA Biosciences’ multi asset pipeline, while bears focus on ongoing losses and execution risk. As you weigh the US$32.85 price tag, the question becomes which side the current valuation leans toward.

Most Popular Narrative: 38% Undervalued

IDEAYA Biosciences is trading at $32.85 against a widely followed fair value estimate of $52.75, so the valuation debate really turns on whether its oncology pipeline can support that gap.

The main factor that needs to go right is successful execution on multiple registrational programs, including darovasertib in uveal melanoma and IDE849 in extensive-stage small-cell lung cancer, while managing trial pivots and competitive pressure in DLL3 therapies.

The current valuation implies that the market is not fully crediting IDEAYA Biosciences for the potential of darovasertib, the MTAP/CDKN2A/KRAS franchise, the DLL3 Topo-ADC program, and a cash balance of about US$1.24b with a stated runway into 2030.

See why 1 investors see IDEAYA Biosciences as 38% undervalued.

Result: Fair Value of $52.75 (UNDERVALUED)

Still, the bullish IDEAYA Biosciences story can break quickly if darovasertib stumbles with regulators or IDE849 struggles to stand out in a crowded DLL3 field.
