AnaptysBio (ANAB) has been removed from several Russell indices, including the Russell Microcap Index and Russell 3000E suite. This is a technical change that can reshape trading flows without reflecting new operational developments.

Over the past year AnaptysBio has combined short term swings with very strong longer term gains, with the share price delivering a 30 day share price return of 25.91% and a 1 year total shareholder return above 300%, even as the latest index removals and recent 1 day and 7 day share price declines signal some cooling in near term momentum.

The latest pullback after AnaptysBio’s index exits sits awkwardly next to its very strong 1 year return and improving revenue and net income trends, so are you looking at a reset in sentiment or a mismatch with the fundamentals?

Most Popular Narrative: 29.5% Undervalued

AnaptysBio’s latest close of $63.42 sits well below the $90 fair value implied by the most followed narrative, which leans heavily on royalty economics and legal optionality.

TLDR: ANAB has a scaling and rising royalty stream, one up and coming new royalty, a loan that dies in 2027 which will result in a doubling of revenue, and a lawsuit that could soon double the value of the stock.

Royalties as a backstop plus a litigation? Yeah, let’s get into it.

Read the complete narrative. Read the complete narrative.

Curious how a focused royalty model, an upcoming loan runoff, and a high stakes legal case combine into a single $90 fair value story? According to TripleS, the narrative leans on rapidly building royalty inflows, expectations around future profitability, and how any litigation outcome could change the cash flow picture. The real swing factor is how those cash flows are discounted, not just where AnaptysBio trades today.

Result: Fair Value of $90 (UNDERVALUED)

However, AnaptysBio’s royalty heavy story still faces real risks, including litigation outcomes that differ from expectations and future product sales that fall short of current assumptions.
