Nuburu, Inc. (NYSE American: BURU) has filed an S-1 registration statement covering up to 450,000,000 shares of common stock — roughly 1.8 times the company's 249,042,796 shares currently outstanding.

The registration breaks into two tranches: approximately 244,372,990 shares and pre-funded warrants offered on a best-efforts basis, and 205,627,010 shares underlying existing conversion rights and warrants. If fully issued, the combined total would bring the diluted share count to approximately 699 million.

Layered dilution mechanics

The filing sits on top of several existing capital-raising instruments, each with its own dilution pathway:

• $100 million Standby Equity Purchase Agreement (SEPA) with Yorkville Advisors, priced at VWAP with no disclosed floor price. This facility allows the company to draw capital by issuing shares at a discount to prevailing market prices on a rolling basis.
• $25 million convertible debenture also held by Yorkville, convertible into common stock at variable, market-linked prices.
• Pre-funded warrants with a nominal $0.0001 exercise price, functionally equivalent to common shares but structured to allow holders to remain below 4.99% and 9.99% beneficial ownership thresholds. These warrants let holders accumulate economic exposure without triggering blockers.

No floor, variable pricing, and anti-dilution resets

The filing carries several structural features that compound potential dilution. The SEPA and convertible debenture both use variable pricing mechanisms tied to VWAP, meaning conversion and issuance prices decline as the stock price falls. No minimum conversion or issuance price floor is disclosed in the filing, removing a safeguard that some similar facilities include.

Outstanding notes, preferred stock, and warrants carry weighted-average anti-dilution provisions. Under these terms, any issuance of shares below the existing conversion price automatically adjusts those instruments' conversion ratios downward, potentially triggering additional share issuance in a self-reinforcing cycle.

Recent reverse split and exchange noncompliance

In February 2026, the company executed a 1-for-4.99 reverse stock split. Prior to that split, shares traded below $0.15. The filing discloses that the company is currently out of compliance with NYSE American listing standards. The reverse split appears designed to address the exchange's minimum price requirement, though the registration of 450 million additional shares introduces substantial overhang relative to the post-split float.

Capital structure context

Nuburu reports an accumulated deficit of approximately $200.9 million and a stockholders' deficit, meaning total liabilities exceed total equity. The company has funded operations through successive equity and debt issuances rather than operating cash flow.

The S-1 is structured as a best-efforts offering, meaning there is no underwriter commitment to purchase unsold shares. Placement depends on market demand at prevailing prices, with the variable-price instruments converting incrementally over time rather than in a single block.
