What the Rights Offering Means — and How It Works

What is a rights offering?

A rights offering is a way for a company to raise money from its own existing shareholders. Instead of selling new shares to outside institutions, it hands every current holder a set of "rights" — short-dated coupons that let you buy newly issued shares, usually at a discount to the market price, in proportion to what you already own.

"Pro rata" is the key phrase: if you own 0.1% of the company today, you get the right to buy 0.1% of the new shares. That's what makes it different from — and friendlier than — a typical secondary offering, where the company sells stock straight to big funds and existing retail holders simply get diluted with no chance to participate.

Why is Eos doing one?

On May 13, 2026, Eos and Cerberus announced Frontier Power USA — a standalone company that will build, own, and operate battery-storage projects using Eos's Z3 technology (the full structure is in the Frontier deep dive). The venture needs equity from both partners:

• Cerberus contributes $100M and is expected to take controlling equity in Frontier Power USA — so the project entity is effectively Cerberus-controlled.
• Eos targets ~$150M — and it intends to raise that money through this rights offering, in exchange for a minority stake in Frontier.

So the rights offering isn't a sign of distress in the usual sense — it's earmarked to buy Eos a seat in an infrastructure vehicle it expects to drive years of recurring battery demand (a 2 GWh Capacity Reservation Agreement already locks in manufacturing for Frontier). But it does mean issuing new stock, which is why the mechanics matter to you.

Your three choices as a shareholder

When the offering opens, every share you own earns you rights. You'll have three options:

Because the rights are transferable, even shareholders who don't want to add cash can recover some value by selling them — which is the shareholder-friendly part. The only choice that leaves value on the table is doing nothing.

The dilution math (worked example)

As of the June 30, 2026 prospectus supplement the terms are set: $5.481 per unit. The simplified example below shows the shape of the dilution; the interactive calculator right after it uses the real unit + warrant mechanics for your own share count.

Two takeaways. First, the dilution is meaningful but not catastrophic — roughly the size of the raise divided by the company. Second, participation is the lever entirely in your hands: exercise your rights and you hold your ground; ignore them and you absorb the full ~7% hit. Note the see-saw: the lower the stock trades when terms are set, the more shares the $150M requires and the bigger the dilution for non-participants.

Run your own numbers

Enter the shares you hold and drag a target price. This uses the actual priced terms — $5.481 per unit, each unit = 1 share + 0.4388 warrant (strike $5.481) — and compares subscribing against putting the same cash into plain stock.

Mechanics: 1 right per share held; 1 right ≈ 0.071193 unit (estimated from a $150M raise ÷ shares outstanding); units round down to whole; each unit = 1 share + 0.4388 warrant (strike $5.481). The plain-stock route spends the identical cash at ≈$5.25. Warrants valued at intrinsic only — selling the warrants on-market before expiry typically adds premium on top, which favours subscribing. Excludes fees, FX and taxes, and your existing shares (identical either way). Scenario math, not investment advice.

The Cerberus warrants — separate, and dilutive too

Alongside the deal, Cerberus is expected to receive warrants on Eos stock — options to buy shares cheaply later. Per the disclosures, those warrants are expected to be priced at a 20% discount to a 15-day VWAP-based exercise price (VWAP = volume-weighted average price; using a 15-day window smooths out single-day spikes).

Why it matters: these warrants are additional potential dilution beyond the rights offering, and they go to Cerberus, not to you. As Cerberus's overall position grows — Series B preferred, prior warrants, the Frontier controlling stake, and now these — its leverage over Eos's capital structure deepens. That's a recurring theme in the bear case worth weighing.

Timeline & conditions — it isn't done yet

The rights offering is announced and backed by a binding term sheet, but several gates must clear first:

What the $150M unlocks

Your ~$150M (via the rights offering) is one leg of a larger capital stack that funds gigawatt-scale storage projects off Eos's own balance sheet:

Is this good or bad for shareholders?

What to actually do with this

If the offering proceeds and you intend to stay a shareholder, the default rational move is to not ignore your rights — either exercise them (to preserve your stake) or sell them (to recover their value). Letting them lapse is the one choice that simply hands value away.

Whether you want to commit more capital comes back to the bigger question the dashboard frames everywhere: do you believe Frontier Power USA turns Eos's technology into durable, owned cash flow? If yes, the rights offering is the on-ramp to that upside at a discount. If you're unsure, selling the rights is the hedge — you participate in the value of the rights without doubling down on the thesis.
