Guardant Health has turned into a high profile story in liquid biopsy, and the stock’s very large 3 year gain now puts a spotlight on a simple question for you as an investor. Do the cash flows that Guardant Health can generate over time support a share price of about US$167 today, or has sentiment moved ahead of what the business currently produces in hard dollars?

  • Over the past 3 years the share price has delivered a very large gain, which puts a lot of weight on whether the underlying cash generation can keep pace with expectations embedded in that move.
  • Fresh approvals for Guardant360 CDx and clinical data on Guardant Reveal can influence how quickly the company turns its testing portfolio into durable revenue and eventually cash flow, as well as how long it may need to keep funding losses and free cash flow burn.

The issue now is whether Guardant Health’s current market value is in line with what its cash flows justify when evaluated using a Discounted Cash Flow (DCF) lens.

Is Guardant Health Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model here hinges on Guardant Health turning sizeable cash outflows into sustained inflows over the next decade. Latest twelve month free cash flow is a loss of about $232.9 million, so the whole exercise depends on the testing portfolio scaling enough to flip that figure into positive territory and keep it there.

The projections assume free cash flow recovers and then grows, with estimates pointing to several hundred million dollars of yearly cash generation by 2030 and beyond. Because this DCF output places Guardant Health’s estimated intrinsic worth meaningfully above the current share price of $167.47, the market is treating the business as relatively expensive today on near term losses, yet still not fully reflecting the longer term cash flow profile implied by the model. The recent CE mark for Guardant360 CDx in Europe helps explain why some investors appear willing to look past ongoing free cash flow burn and lean on that longer runway of projected cash generation.
