Semler Scientific has filed with the US Securities and Exchange Commission to offer $500 million in securities to potentially expand its bitcoin holdings and cover general corporate expenses. The company, which embarked on a bitcoin investment strategy in May 2024, aims to use the funds from the various securities sales, including debt securities, common stocks, and warrants, primarily for acquiring more bitcoin, alongside other corporate needs. As of now, Semler holds 3,192 BTC with an unrealized loss of approximately $14 million.
