Collaboration Revenue Plummets
Collaboration revenue for the full year 2025 drastically decreased to $21.0 million from $100.6 million in 2024, primarily due to the satisfaction of performance obligations related to the AL002 program and the latozinemab FTD-C9orf72 Phase 2 trial in late 2024.

Net Loss Significantly Widens
The company reported a net loss of $142.9 million for the full year 2025, a substantial increase from a net loss of $119.0 million in 2024. The fourth quarter net loss also widened significantly to $37.3 million from $2.1 million in the prior year.

Reduced Operating Expenses
Research and development expenses decreased to $123.1 million for the full year 2025 from $185.9 million in 2024, and general and administrative expenses also declined, largely due to workforce reductions.

Cash Runway Through 2027

Analysis · ALEC · Life Sciences
Alector, Inc. announced significantly weaker financial results for the fourth quarter and full year 2025, marked by a drastic reduction in collaboration revenue and a substantial increase in net loss. This financial deterioration follows the trends highlighted in the concurrently filed 10-K, which noted increased net losses, a drastic drop in collaboration revenue due to multiple clinical trial failures, and extensive workforce reductions. While the company maintains a cash runway through 2027, the sharp decline in revenue and widening losses indicate significant operational challenges. Investors should monitor the upcoming interim futility analysis for the PROGRESS-AD Phase 2 trial and the presentation of INFRONT-3 Phase 3 trial results, as these clinical milestones are critical for future prospects.
