What this transaction means for investors

There are many reasons an insider may sell, some of which have nothing to do with the business’s prospects, such as the need to pay a large personal expense or to pursue prudent diversification.

There is only one reason an insider buys stock: they expect the price to go up.

Robert Mashal joined the board of directors of Nuvation Bio at the start of 2024. The executive, a trained medical doctor in oncology, has been the CEO of other developmental-stage biopharmaceutical companies and a pharmaceutical-focused venture capital investor.

While Mashal has received a number of stock options as part of his service on the board of directors, the fact that he is now spending his own money on an open market purchase is bullish. That he has done so after a strong rally in NUVB, up nearly double in the past 52 weeks, is even more so.

Last July, Nuvation’s first FDA-approved product, named Ibtrozi, hit the market to treat a type of non-small cell lung cancer. In each of the three reported quarters since, more than 200 new patients have started Ibtrozi, which is bullish for a niche treatment like Nuvation’s offering. One can assume Mashal expects the drug to continue to be embraced by doctors and patients. Wall Street thinks so too, projecting Nuvation revenue will hit nearly $203 million this year, up from almost $63 million in 2025.
