PONO merger with Blackstar Orbital
Blackstar Orbital Technologies Corporation is developing reusable orbital spacecraft designed to launch aboard existing rockets as conventional payloads, operate in low Earth orbit, return mission payloads to Earth … (United States)
Expected close, as filed: Q1 2027.
Announced 6 August 2026.
Blackstar Orbital Technologies Corporation, founded in 2023 and headquartered on Florida's Space Coast in Titusville, is an aerospace and defense company developing a reusable orbital spacecraft platform called SpaceDrone. The company's flagship vehicle, the BX-100, is a lifting-body spaceplane designed to launch aboard existing rockets as a conventional payload, operate in low Earth orbit, and then return to Earth with a runway landing for recovery and reuse. The vehicle can carry up to 100 kg to LEO, supports powered payload hosting with downlink capability, and is engineered for approximately 100 flights per airframe with a 48-hour turnaround between missions. Blackstar offers three configurations of the BX-100: a modular variant for science and R&D missions, a defense variant designed for rapid call-up and on-orbit reconstitution, and a CubeSat dispenser variant for constellation deployment. The company also markets SpaceBox, a certified container that lets customers fly products to space and back with no engineering on their side. Blackstar's SpaceBox has already flown on Axiom-4, marking the company's first returned flight hardware.
The company is led by President and CEO Christopher Jannette, who has framed Blackstar's mission around the premise that today's satellites are designed without a return path. By integrating orbital operations, payload return, and runway recovery into a single platform, Blackstar aims to serve both government and commercial customers with responsive, repeatable access to orbit and the ability to recover high-value payloads, technologies, and materials from space. The company has secured approximately $1.9 million in cumulative U.S. government research and development funding, including awards through SpaceWERX, the innovation arm of the U.S. Space Force, as well as participation in NASA's Tipping Point program and the U.S. Space Force's Orbital Prime initiative. On the commercial side, Blackstar reports over $120 million in signed letters of intent from customers spanning in-orbit servicing, in-space compute, and other space economy segments. The company has also established strategic partnerships with Starfighters Space for F-104-based flight testing of the SpaceDrone, Phantom Space for launch collaborations, and KMI for active debris removal missions.
Blackstar has raised roughly $31 million in total funding across a seed round closed in May 2024, a $30 million Series A in August 2024, debt financing, and accelerator programs. Its investors include Seraphim Space, Space Florida, Space-Edge, and CT Holdings. The company employs approximately 10 people and is reportedly generating revenue. Its technology has been classified under multiple categories including reusable satellites, re-entry transport services, space tugs, and microgravity flight services, reflecting the breadth of mission types the SpaceDrone platform is designed to support.
On August 6, 2026, Blackstar announced a definitive merger agreement with Pono Capital Four, Inc. (NASDAQ: PONO), a special purpose acquisition company led by Dustin Shindo, in a stock transaction valuing Blackstar at $380 million. The deal structure involves Blackstar merging with a Pono subsidiary and continuing as the surviving corporation, with Pono subsequently renaming itself Blackstar Orbital Corporation. Approximately 25% of the merger consideration shares will be escrowed for six years to secure indemnification and litigation claims, and an additional equity incentive plan reserve of up to 6 million shares is planned. The transaction, which has been unanimously approved by both boards, is expected to close in the first quarter of 2027, subject to shareholder approvals, regulatory clearances, and Nasdaq listing conditions. Blackstar's leadership framed the SPAC route as a way to accelerate the company's path toward making repeatable access to and return from orbit a practical capability, positioning Blackstar to become a global leader in the prem

from 8-KThe business actually being bought — described from SEC primary filings, with projections labelled as projections.
Blackstar Orbital Technologies Corporation is developing reusable orbital spacecraft designed to launch aboard existing rockets as conventional payloads, operate in low Earth orbit, return mission payloads to Earth, and land on a runway for recovery and reuse. Its flagship SpaceDrone platform is intended to provide government and commercial customers with responsive, repeatable access to orbit and the ability to recover high-value payloads, technologies and materials from space. The company states it has been awarded approximately $1.9 million in cumulative U.S. government research and development funding, including awards through SpaceWERX, and has secured over $120 million in signed commercial letters of intent.
Blackstar Orbital — every SPAC that has bid for it, and its listed peers
Expensive or cheap?
vs 7 listed peersA price only means something next to what the same kind of business costs on the stock market. This divides what the buyers are paying by what Blackstar Orbital actually sells, and sets the answer against its closest listed comparables — or says plainly when that cannot be done.
SpacBrain’s read on the price
No multiple can be computed
We hold no revenue figure in US dollars for Blackstar Orbital, so there is nothing to divide the price by and no multiple can be struck. It is not recorded as pre-revenue either — this is a gap in our record, not a finding that the company has no sales. The deal values it at $551.4M regardless.
We have not extracted a revenue figure for this company from its filings yet. That is our gap, not a statement about the business.
Post-dilution equity (net debt unknown).
Not extracted from the filings yet.
Not computable — no revenue figure has been extracted from the filings yet.
$1 of their sales costs $8.39 on the open market. Median of 7 listed companies we judged a true comparable, which individually run from 2.11× to 196.45×. Their share prices are from 14 August 2026, not today.
What qualifies the figures above
- Struck on the post-dilution value of $551.4M, not the announced $380M — new shares handed to the sponsor, warrant holders and the PIPE are part of what public buyers are really paying.
- The target's cash and debt are not in the filings we have, so this is an equity value used as a stand-in for enterprise value.
- FLY, YSS, VOYG, KRMN, FJET have no revenue to divide by, so they are shown but left out of the peer median.

Which companies count as comparable is our judgement, written out above so you can disagree with it. The median is what these shares happened to trade at on the date given — not a price anyone is offering for this deal.
In plain English
No floor / floorlessthe cash guarantee is gone — the price is unprotected
A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.
Dilutionhow much of the company new shares take from you
Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.
Pro-forma equitywhat the company is valued at once the deal closes
The combined company's equity value assuming the announced terms and the redemptions that have actually happened.
De-SPACthe day the SPAC becomes the real company
The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.
Outside datethe contractual long-stop for closing the deal
A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.
