Seer, Inc. (US8158581079) stock fell 3.12 percent after TradingView said President, CFO and Treasurer David Horn will depart on October 1, 2026. Seer shares changed hands at USD 1.86 in GuruFocus' September 21, 2026 update, and the platform put the company's market capitalization at USD 103 million.

CFO change hits the tape

According to TradingView, Charles Endweiss will become Treasurer, principal financial officer and principal accounting officer on October 1, 2026. That internal handoff gives the company a named successor on the finance side, even as the market marked the shares down 3.12 percent.

On the same day, GuruFocus said Seer's price-to-sales ratio stood at 7.5x, below its historical median of about 9.3x. The site also described the company as unprofitable and said earnings-based valuation metrics are not meaningful while cash flow stays negative.

Valuation stays fragile

GuruFocus put Seer's GF Score at 53 out of 100 and said the stock's intrinsic value was USD 2.07 versus a current price of USD 1.86, a gap of 10.1 percent. That places the latest quote below the model value, but the same update still points to weak profitability and mixed insider activity.

For investors, the key number is the size of the company: USD 103 million in market value is small for a listed biotech name, so even a finance leadership change can matter quickly. The same update also cited 0 insider purchases and USD 0.2 million in insider selling over the past 12 months.

Stock near USD 1.86

SEER stock stood at USD 1.86 on September 21, 2026, with a market capitalization of USD 103 million and a 3.12 percent move tied to the leadership update. The next catalyst is the handover on October 1, 2026, when Charles Endweiss takes over the financial role.
