Announced ZEE, Archer’s AI foundation model purpose-built for aviation and its frontier breakthrough for aviation safety
2UNLOCK THE SKIES Q2 2026 SHAREHOLDER LETTER3 Dear Shareholders, Today, we announced that we entered into agreements to acquire Wisk Aero, Insitu, and SkyGrid, three highly innovative Boeing-owned companies, in exchange for Boeing taking a strategic equity stake in Archer1.
We anticipate closing the transaction by year end.
This transaction will help accelerate our evolution into becoming a diversified aerospace and defense platform.
After closing, our product portfolio will span piloted air taxis, unmanned aircraft systems (UAS) in Groups 2 through 5, purpose-built AI for aviation, and the vertical technology stack for autonomous flight.
Let me walk you through the transaction rationale in more detail.
Archer got its start by standing up a world-class team to find the most efficient path to commercializing the air taxi industry.
That will always be core to our mission, and Midnight is well on its way to achieving that.
We went from an unknown in 2018, to today leading the air taxi industry in certification progress with the FAA.
As I've talked about over the last 18 months, defense is becoming an increasingly large near-term market for autonomous VTOL.
Last month, with our partner Anduril, we revealed our Group 5 Halo/Thunder platform, a clean-sheet, autonomous, hybrid-electric VTOL aircraft for both commercial and defense.
Thunder, Anduril’s missionized defense version of Halo, aims to serve as a loyal wingman for reconnaissance attack helicopters, like the Apache, targeting multi-decade programs of record across allied forces.
It's become increasingly clear that the combined market for this Group 5 platform is massive.
And in addition to the revenue, deploying nascent tech early in defense can deliver value across Archer’s entire business, with benefits like autonomy and lower costs flowing back into our air taxi products.
Over the past year, we have been assembling a focused team for Halo/Thunder to build the autonomy, flight controls, sensor integration, and flight test capabilities.
Wisk will help us round out this team.
8We are acquiring Wisk to accelerate the Halo/Thunder platform, which I believe will be a generational vertical lift program.
Wisk has developed some of the most advanced autonomy, flight controls, and sensor technologies in the industry.
We plan to deploy that technology on Halo first, so that we can harden it and then bring it back to the air taxi platform when the FAA is ready to certify autonomy for passenger air taxis.
3I am confident that our planned acquisition of Wisk can accelerate Halo/Thunder R&D at a fraction of the time it would have taken us to achieve the same results organically.
1 Transaction is subject to agreed-upon closing conditions, including regulatory approvals.
UNLOCK THE SKIES Q2 2026 SHAREHOLDER LETTER4 2 Based on Insitu’s current financials and financial estimates.
5As part of this transaction, we are also set to acquire Insitu, one of the most trusted and reputable intelligence, surveillance, and reconnaissance (ISR) drone manufacturers, operating profitably with over $200M in annual revenue across 35 countries2.
4Insitu, which has manufactured over 4,000 Group 2 and Group 3 UAS to date, will give Archer an immediate, sizeable revenue base to grow in the near term.
Its fleet has flown nearly 2 million autonomous flight hours, building one of the largest datasets of its kind, key to our autonomy development.
This transaction with Boeing would not have been possible without the relationship we have cultivated with Boeing over the last couple of years.
Boeing is synonymous with American aviation, and our deal structure demonstrates how leaned in they are on our future together: taking all stock with a lockup, planned collaboration with us across many fronts, and commitment to future equity investment in Archer.
A core value proposition for us both is the opportunity to jointly drive innovation in aerospace, defense, and autonomy and deliver long-term value for shareholders.
I want to thank Kelly Ortberg and the Boeing leadership for their trust and belief in Archer as the right long-term partner.
Last quarter, I called Archer a “dual-threat” company because we are commercializing both an air taxi and our dual-use autonomous VTOL aircraft platform.
Over the last couple months, we've shared more on our strategy for purpose-built AI for aerospace and defense.
We introduced ZEE, the world's leading aviation-specific foundation model, a unified intelligence platform built on ADS-B, ATC communication, maps and charts, aircraft movements, terrain, and weather data, designed to run on-device across environments from air taxis and UAS to commercial airlines and air traffic management.
And just last week, we announced that the model delivered a frontier breakthrough in aviation safety: highly accurate real-time airport surface trajectory prediction.
To safely adapt this technology into the aviation ecosystem, our teams are working with government agencies and customers to rigorously validate ZEE in the real world.
In fact, we've already begun testing ZEE at Hawthorne Airport, our future LA air taxi hub.
SkyGrid is highly complementary to ZEE as it has been developing next-generation airspace management solutions since 2018.
That tech is in use today, and I believe SkyGrid plus ZEE can become a ”must have” air traffic management product that helps modernize airspaces around the world.
I see a clear path to significant AI revenue, and the team is heads-down building toward that.
Management commentary
UNLOCK THE SKIES Q2 2026 SHAREHOLDER LETTER5 I am confident that the other side of this transaction with Boeing is a stronger Archer with a groundbreaking end-to-end physical AI platform for aerospace and defense.
I’ve tasked my team with integrating these companies to do so in a thoughtful and synergistic way that will not structurally increase our overall cash burn.
Through it all, our commercial Midnight program continues to accelerate and remain a top priority at Archer.
7Recently, we flew our first intercity flights in California, and over the next few months, we plan to begin flying in the Los Angeles area based out of Hawthorne Airport, and subsequently commence operations under the White House’s eIPP later this year in Texas.
Beyond flight test, our team has also been hard at work on the infrastructure front.
This quarter we jointly launched an industry-first consortium with BETA and Macquarie to scale charging infrastructure across the U.S and unify a single approach for OEMs and vertiport developers.
I’m proud to do that arm in arm with Kyle and the team at BETA.
I started Archer to change the way the world moves.
Nearly a decade in, I've never been more confident, or more all in.

UNLOCK THE SKIES Q2 2026 SHAREHOLDER LETTER10 OTHER HIGHLIGHTS FROM THE QUARTER Unveiled Halo/Thunder: Archer’s Dual-Use Autonomous, Hybrid VTOL Platform With Anduril In July, Archer and Anduril unveiled their jointly-developed autonomous, hybrid VTOL aircraft platform at the Farnborough International Airshow, introduced as Thunder for defense missions and Halo for commercial applications.
The two variants share the same airframe, hybrid powertrain and core systems, with configurable payload depending on mission requirements.
Announced ZEE, Archer’s AI Foundation Model Purpose-Built For Aviation Archer announced ZEE, its AI foundation model purpose-built for aviation, delivering a unified aviation intelligence platform built on ADS-B, ATC communication, maps and charts, aircraft state, terrain and weather data.
The foundation model is designed to work both offline, on-device and as a server-hosted solution, critical for use in a wide range of aviation environments from air taxis and UASs to commercial airlines and air traffic management.
6Completed City-to-City Midnight Flights In Preparation for eIPP Operations In July, Archer's Midnight aircraft completed a piloted round trip journey between Salinas Municipal Airport and Monterey Regional Airport, with each leg completed in approximately nine minutes compared to over 35 minutes by car.
The flight was executed in close coordination with the FAA and marks a critical step toward Archer launching Midnight operations later this year under the eIPP.
