Tectonic Therapeutic delivered a clean quarter with clinical execution on track. The completion of enrollment in the pivotal TX45 APEX Phase 2 trial and a positive IDMC review de-risk the program ahead of topline data in early 2027. The cash position of $227.1 million, bolstered by $11.7 million in ATM proceeds, extends the runway into Q1 2029 — well past both the TX45 and TX2100 readouts. The net loss widened modestly to $22.3 million, in line with increased R&D spending. The TX2100 Phase 1a dosing completion and upcoming data by end of Q3 2026 add a near-term catalyst. Overall, the update reinforces the investment thesis with no negative surprises.
