Brenmiller Energy Ltd. (NASDAQ: BNRG) has a 5,905,055-share resale registration — a filing that would allow an investor to sell newly converted or exercised shares on the open market — pending before the SEC. That figure represents roughly 2.8 times the company's entire current public float of approximately 2.1 million shares.

The structural picture behind that number is worth examining in detail.

How the share count got here

As of June 17, 2026, BNRG reported 2,119,336 ordinary shares outstanding. That is up from 715,852 at year-end 2025 — a 196% increase in under six months. The growth occurred after a 5-for-1 reverse split in April 2026, itself the third reverse split in twelve months (following a 5-for-1 in June 2025 and a 7-for-1 in January 2026). Each consolidation was followed by renewed issuance.

The company has 150 million shares authorized. It has used roughly 1.4% of that capacity so far.

The Alpha Capital facility

Virtually all recent issuance traces to a single counterparty: Alpha Capital Anstalt, a Liechtenstein-domiciled structured-finance firm. Alpha entered a $25 million securities purchase agreement in July 2025 structured as a multi-tranche convertible preferred PIPE — a private placement of preferred shares that convert into ordinary stock at a set price.

The critical term is full-ratchet anti-dilution. That means whenever the company issues shares at a lower price, the conversion price on all previously issued preferred shares automatically resets downward to match. The conversion price has already ratcheted from $3.39 to $1.67 within weeks. Each drop increases the number of ordinary shares Alpha is entitled to receive. At $1.67, the 4,212 preferred shares outstanding convert into approximately 1,025,150 ordinary shares — equal to roughly 48% of the current float.

Alpha is capped at 9.99% beneficial ownership at any given time via a blocker provision. In practice, this allows a cycle: convert up to the limit, sell, then convert again.

Pending supply overhang

The June 18, 2026 resale registration covers preferred conversions, 200% anti-dilution share coverage, and multiple warrant tranches — all for Alpha's benefit. A separate 1,448,371-share resale shelf was filed May 6. On top of both, the company filed a $75 million primary shelf registration on June 4, listing at-the-market sales — continuous issuance directly into the open market at prevailing prices — as a distribution method. An ATM program is already active: 407,783 shares were sold for $1.1 million net between December 2025 and June 2026.

Additional pending supply includes 75,000 pre-funded warrants — warrants priced at $0.00001, making them economically equivalent to issued shares — awaiting shareholder approval, plus 1,000,000 new $2.00 warrants and the potential repricing of roughly 1.5 million existing warrants from $14.56 down to $2.00.

Dilution risk grade: 9 out of 10

ShareStructure assigns BNRG an Extreme dilution risk rating. The score reflects the combination of a full-ratchet conversion mechanism that automatically expands share issuance as prices decline, monthly funding cadence (two closings in June 2026 alone), serial reverse splits, and pending registrations that could multiply the float several times over within 90 days of effectiveness.

Major float-data services still show BNRG's float near 489,000 shares — a figure that predates roughly 1.6 million shares of H1 2026 issuance and understates the tradeable supply by more than four-to-one.
