1 Main Capital stated the following regarding Third Harmonic Bio, Inc. (NASDAQ:THRD) in its Q1 2025 investor letter:

“Third Harmonic Bio, Inc. (NASDAQ:THRD) came public in 2022, and its shares quickly came under pressure after the company reported that THB001, its primary drug, caused liver toxicity issues in trials. In February 2025, phase 1 data for another pipeline asset, THB335 (“335”), also disappointed investors.

Concurrent to releasing the 335 results, THRD halted all non-335 research, fired 50% of its workforce, and initiated a strategic review, saying “we have to consider our responsibility to our shareholders and our ability to build value over a reasonable time horizon…given the recent market dynamics around our stock, we believe that solely relying on the progress of 335 to build value is an inefficient approach.”

On the same day, THRD guided to a 6/30/25 estimated net cash balance of >$5 per share with nearly no liabilities, at which point the Fund bought shares at $3.45. In mid-April the company announced it would dissolve itself and return all its cash to shareholders. We then exited at $5.”
