Exhibit 99.1
Blackstar Orbital Technologies, an innovative
developer of advanced reusable spacecraft announces the signing of a definitive agreement to go public via a business combination with
Pono Capital Four, a Nasdaq listed company.
Cayman Islands and Space Coast, Florida, Aug.
06, 2026 (GLOBE NEWSWIRE) -- Pono Capital Four, Inc. (NASDAQ: PONO, PONOU and PONOR), a special purpose acquisition company (“Pono”),
has announced the execution of a definitive Agreement and Plan of Merger (the “Merger Agreement”) with Blackstar Orbital
Technologies Corporation, a Delaware corporation (“Blackstar Orbital”). Pursuant to the Merger Agreement, it is intended
that Blackstar Orbital will merge with Pono Four Merger Sub, Inc., a wholly owned subsidiary of Pono, with Blackstar Orbital continuing
as the surviving corporation as a wholly owned subsidiary of Pono. Stockholders of Blackstar Orbital will receive shares of Common Stock
of Pono (the “Merger”). In connection with the Merger, it is expected that Blackstar Orbital Technologies Corporation will
remain as the name of the wholly owned subsidiary and that Pono will then change its name to “Blackstar Orbital Corporation”.
Pono and Blackstar Orbital believe that, if consummated, the Merger
will promote the expansion of Blackstar Orbital’s business globally, as Blackstar Orbital will be better positioned to become the
global leader in the premium orbital down mass and advanced high-performance satellite market.
Blackstar Orbital is developing SpaceDrone™,
a reusable orbital spacecraft platform designed to launch aboard existing rockets as a conventional payload, conduct missions in low Earth
orbit, carry mission payloads back from orbit, and land on a runway for recovery and reuse. By integrating orbital operations, payload
return and runway recovery into a single platform, Blackstar Orbital intends to enable more responsive, repeatable and flexible space
missions for government and commercial customers.
“Today’s satellites are generally
designed without a return path. Blackstar Orbital is developing a spacecraft platform built around recovery, reuse and reflight,”
said Christopher Jannette, President and CEO of Blackstar Orbital. “SpaceDrone is designed to launch aboard existing rockets, operate
in low Earth orbit, return mission payloads to Earth and land on a runway. We believe this transaction will accelerate our path toward
making repeatable access to and return from orbit a practical capability for government and commercial customers.”
Blackstar Orbital has been awarded 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, to advance the design, testing and maturation of its reusable spacecraft platform. The company has secured over
$120 million in signed commercial LOIs from an expansive range of customers from in orbit servicing to in space compute.
“We believe Blackstar Orbital’s approach
to deploying and relaunching hypersonic satellites will help drive the space economy through greater efficiency and turnaround times.”
said Dustin Shindo, CEO of Pono.
According to the Satellite Industry Association’s
2026 State of the Satellite Industry Report, the commercial satellite industry generated $303 billion in revenue in 2025 and accounted
for 71 percent of the $429 billion global space economy. The report also found that a record 4,434 satellites were deployed into Earth
orbit during 2025, a 65 percent increase over 2024, demonstrating the scale and continued growth of the broader commercial space sector
that Blackstar Orbital intends to serve.
Transaction Overview
The transaction values Blackstar Orbital at $380 million. The cash
proceeds raised in the transaction, after any redemptions and payment of transaction expenses, are currently anticipated to be used for
the further development of the Blackstar Orbital technology and for general company operating purposes.
The boards of directors of Pono and Blackstar Orbital have unanimously
approved the Merger Agreement and the proposed transactions. The closing of the Merger and related transactions are subject to approval
by Pono shareholders and Blackstar Orbital’s stockholders and are also subject to other customary closing conditions. It is currently
expected that the transaction will close in the first quarter of 2027, assuming such closing conditions are met.
