Schedule 13G/Aregulatory
"Amendment No. 1 and Schedule 13G/A reference"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
beneficial ownershipfinancial
"Each Reporting Person disclaims beneficial ownership of the shares described above"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

Exhibit Information
24.1 Power of Attorney for Vinod Khosla
99.1 Agreement regarding joint filing of Schedule 13G
Vinod Khosla and affiliated entities are reported as beneficially owning 1,798,702 shares, representing 4.0% of common stock based on 44,452,734 shares outstanding as of May 1, 2026. The filing attributes the percentage change to the updated share count.
Why did Khosla entities amend their Schedule 13G for BIOA?
They amended to reflect a change in percentage ownership resulting solely from the issuer's updated outstanding share count of 44,452,734 as of May 1, 2026. The reporting persons state no other ownership changes and voluntarily filed because their ownership decreased below 5%.
How many shares do Khosla Ventures Opportunity I and KV VI respectively report?
Khosla Ventures Opportunity I reports beneficial ownership of 1,361,550 shares (3.1%) and Khosla Ventures VI reports 437,152 shares (1.0%), calculated using the issuer's 44,452,734 shares outstanding as of May 1, 2026.
Does this filing indicate any direct sales or purchases of BIOA stock?
No. The amendment states the percentage change is solely due to the updated outstanding share count on the issuer's Form 10-Q; the reporting persons assert they made no other ownership changes in connection with this filing.
