Company & revenue
About Assembly Biosciences, Inc.
Primary reporting period: 2025-12-31 · Research updated Oct 12, 2026. A research update is not a new financial filing.

How they make money
Assembly Biosciences is a clinical-stage biotechnology company that generates revenue primarily through research and development collaborations and licensing agreements. The company focuses on discovering and developing small-molecule therapeutics for serious viral diseases, and its business model relies on milestone payments, royalties, and research funding from strategic partners rather than commercial product sales.

WSS View
The quick read
The overall Wall Street Score is low across its combined quality, valuation and risk inputs. This can reflect an expensive share price, business weaknesses, or both; check Company Quality and the category breakdown before drawing a conclusion.
At today’s price, the WSS valuation framework currently reads as less attractive based on the available valuation and market data.
The model outlook is currently cautious.
- •Asset quality scores strongly
- •Valuation is a weaker part of the current profile
- •Revenue fundamentals are weak

Momentum & Volatility Signals
Two different market-behavior signals. Momentum measures direction and trend strength. Volatility measures how large and unstable the price moves are, regardless of direction.
Strong downward momentum
Normal movement
A high momentum score means price has been trending upward with confirming short- and medium-term strength. A low score means downward or weakening momentum.
A high volatility score means larger, less stable price swings. It can happen while a stock is rising or falling, so high volatility is not automatically bullish or bearish.
Important: the volatility score above is based on realized price volatility. Implied volatility (IV) comes from options prices and represents the market's expected future movement. Wall Street Score will keep IV separate and will only display it when a verified options-chain feed is available.

Large reported revenue change: +153.5%
Revenue changed sharply from 2024 to 2025. This can reflect a real business change, acquisition, divestiture, discontinued operations, restatement, or reporting-basis change. Compare the underlying filing before treating it as normal growth or decline.
TTM may combine quarters from before and after the event, so its trend can also be distorted.
Free includes 3 annual periods plus available TTM; Premium includes up to 10 annual periods. History depends on available company filings. Swipe the table horizontally to see older periods. A dash means unavailable, not zero.
