Q4 & FY 2025 SHAREHOLDER LETTER \| UNLOCK THE SKIES 3 Dear Shareholders, I founded Archer with the vision to build the world's first certified electric air taxi. That vision evolved over the last seven years. Today, Archer is a next-generation aerospace company building the technologies that will power the next 100 years of vertical flight across commercial and defense. It is often forgotten that Archer was founded more than a decade after others in the industry. We entered the development cycle at a key inflection point: the foundational technologies were ready for commercialization and we were still early enough to help shape the regulatory framework. We did not have legacy tech debt, so we developed a clean sheet design using a first principles approach, focused on finding the most efficient path to certification and commercialization. We've assembled what I believe to be the best team in aerospace and gave them a clear mandate. I believe our strategy is paying off in ways the market is only beginning to understand. A few months ago, we added a new Midnight aircraft to our fleet. It completed ground testing faster than any before it and is now flying piloted vertical takeoff and landing operations at our flight test facility in California. Later this year, we plan to deploy additional piloted Midnight aircraft in American cities through the White House's eVTOL Integration Pilot Program (eIPP) and in the UAE through our commercial launch program. Everything we have built over the past seven years is converging. Let me walk you through how we got here and what you can expect in 2026. Flight Test & Manufacturing Last year, our pilots took Midnight through its CTOL campaign: flights of over 50 miles, in excess of 30 minutes of flight time, altitudes above 10,000 feet, and speeds of 150 miles per hour. The FAA recently issued our newest Midnight aircraft its special airworthiness certificate and with its piloted VTOL campaign underway it will progress through increasingly advanced test points as it works toward piloted transition flight in the coming months. We will continue to expand our Midnight fleet and the flight envelope throughout 2026, with several aircraft in various stages of completion across our facilities in Georgia and California, supporting our planned TIA activities with the FAA as soon as this year.

Q4 & FY 2025 SHAREHOLDER LETTER \| UNLOCK THE SKIES 4 Commercial Launch On the commercial front, we plan to begin operating Midnight this year, both in American cities as part of the eIPP and in the UAE as part of our commercial launch program. Last year, President Trump signed an Executive Order, "Unleashing Drone Dominance," that established a White House mandate to accelerate air taxi deployments in American cities. Since then, my team and I have been working directly with the DOT and FAA to help ensure this program positions our country to lead the world in this new category. We have submitted applications across California, Florida, Texas, Georgia, and New York. The first time I saw a Waymo on the road in San Francisco, it was a big deal. Now, self-driving cars are just part of everyday life there. I believe the eIPP will do the same thing for air taxis. Every safe flight builds towards public acceptance, and we need to build that acceptance in parallel with our certification efforts. Our launch program in the UAE is built around the same premise. We have been working closely with the GCAA, the UAE's federal aviation regulator, over the past year to determine the most appropriate regulatory pathway. Together, we chose a Restricted Type Certificate approach, and Archer is the first eVTOL manufacturer to establish this pathway with the GCAA. Last year, we initiated hot weather flight testing with Midnight in Abu Dhabi, and this year, we are on track to deliver additional piloted Midnight aircraft for passenger operations. In parallel, our team continues building out our network of vertiports across Abu Dhabi. Our progress in the U.S. and the UAE continues to catalyze our global demand. Our order book\* is in the billions, with seven of the world's largest airlines choosing to partner with us. In Q4, Saudi Arabia's PIF partnered with Archer to deploy aircraft\*\*, starting with Red Sea Global\*\*. Korean Air selected us as its exclusive partner, and our consortium with Japan Airlines was selected to support commercialization in both Osaka and Tokyo. Certification This quarter, we reached a key milestone: the FAA confirmed its final acceptance of 100% of the 797 Means of Compliance for our Midnight aircraft. I believe this makes us the first \*Order book values represent the Company's estimate based on an indicative $5M per aircraft price. This is only a prediction and actual results may differ materially due to a variety of factors. In general, our agreements related to aircraft orders remain conditional, subject to the execution of further definitive agreements and the satisfaction of certain conditions. \*\*Agreements with the partners discuss above remain conditional, subject to the execution of further definitive agreements and the satisfaction of certain conditions.

![](archerlettertoshareholde005.jpg)

Q4 & FY 2025 SHAREHOLDER LETTER \| UNLOCK THE SKIES 5 to achieve this milestone with the FAA. I am proud of our team for getting us there first. Completing our Means of Compliance unlocks our ability to finalize the acceptance of our remaining certification plans with the FAA. We expect those to be resolved in the coming quarters, clearing the path for Type Inspection Authorization (TIA) work to begin on our Midnight program as soon as this year. To simplify our path to certification, we designed Midnight to be as close to a Part 23 airplane as possible. We chose not to reinvent what did not need reinventing. We vertically integrated only where necessary, the powertrain and flight control software, because no supply base existed for those, and we partnered with Tier 1 aerospace suppliers for the rest. The result: Midnight requires only 17 issue papers with 13 being industry-standard and 4 unique to our design and battery pack. The more novel the aircraft design, the more issue papers it requires, and the more certification risk it carries. We have been disciplined about working within the defined pathway, and that discipline is the reason I expect we will continue to progress more quickly than others. Over the last seven years, what I have learned is that the hardest part of designing an eVTOL aircraft is perfecting the balance between (1) performance, (2) certification, and (3) mass manufacturability. You can design and build an eVTOL that performs beautifully. But try to certify it, and meeting the FAA's standards often requires you to add complexity and weight. That weight hurts performance and the complexity makes it harder to manufacture at scale. The design falls on its face. The key is solving all three simultaneously, and that is what we as an industry are all grappling with. Midnight's aft propellers are a design trade we get asked about. Our team explored two-, three-, and four-bladed options. Two-bladed carried the most mechanical complexity and required dampeners that added weight. Four-bladed eliminated the dampeners, saving weight, but impacted drag. Because the two-bladed solution increased complexity in ways that made the aircraft harder to certify and manufacture, we chose four blades. Four reduces complexity, makes certification more straightforward, and maintains manufacturability with minimal performance impact. Another design choice worth explaining: we built Midnight to certify both vertical and conventional takeoff and landing. VTOL is what makes air taxis possible in cities, but CTOL

Q4 & FY 2025 SHAREHOLDER LETTER \| UNLOCK THE SKIES 6 capability gives Midnight two distinct advantages. First, safety: in an emergency, Midnight can land conventionally without putting pilots or passengers at risk. Second, operational flexibility: a conventional takeoff uses far less energy than a vertical one, so when a runway is available on one leg of a trip, we'll have the option to use it, extending range and reducing charge time. These are the kinds of pragmatic design choices we made that I believe will give Midnight the winning hand. Defense The defense industry is shifting its focus from expensive, exquisite systems to autonomous, attritable platforms built for scale. On the fixed-wing side, you have already seen this with collaborative combat aircraft like Anduril's Fury, designed to fly alongside existing piloted fighter jets. That same transformation is coming to rotorcraft and is the opportunity we are trying to seize. Our partnership with Anduril is at the core of our defense strategy, and it continues to accelerate. We are designing an autonomous, hybrid-electric VTOL aircraft built for dual use. For defense, it will fly alongside armed reconnaissance attack helicopters as a loyal wingman. The aircraft is designed to meet the needs of the U.S. and its allies for decades to come. For commercial customers, the aircraft will be tailored for cargo or medevac. To support this effort, we opened a new engineering hub in Bristol, UK, and have already hired a team of 20+ local engineers. We have also found select opportunities to adapt the proprietary technologies we have built for our commercial aircraft and bring them to other applications. In November, we announced our first third-party powertrain deal with Anduril and EDGE Group to power their Omen autonomous air vehicle. Anduril spent five years searching for a propulsion solution for Omen. They chose ours because our powertrain de-risks their path to scaled production. Autonomy Autonomy in aviation is fundamentally different from autonomy on the ground. With cars, the challenge is building systems that handle the entire driving task end to end. In aviation, autopilot already manages the vast majority of a commercial flight. Pilots handle taxiing, takeoff, and landing. The challenge is bringing automation to the air traffic control system.

Q4 & FY 2025 SHAREHOLDER LETTER \| UNLOCK THE SKIES 7 The current system relies on legacy communications, such as VHF voice radio, that cannot support the continuous exchange of telemetry, intent, and situational awareness that autonomy requires. President Trump's One Big Beautiful Bill allocated a historic $12.5 billion to modernize the air traffic control system in the U.S. Autonomy requires a modern data backbone to support continuous exchange of telemetry, intent, and situational awareness between aircraft, ground stations, and supporting infrastructure. We are working to build a full-stack solution that will help bring autonomy to our airspace and plan to unveil our first software product in this category later this year. We are positioning Archer to be ready for this shift and plan to use our recently acquired Hawthorne Airport as a testbed for these technologies. Over the last year, we put the key pieces in place. We partnered with Palantir to build the AI foundation for next-generation air traffic control, movement control, and route planning. We are working with NVIDIA to integrate their IGX Thor platform into Midnight, which will enable real-time onboard computing for safety-critical autonomy applications. And we are working with SpaceX's Starlink to bring high-speed, low-latency connectivity to our aircraft. You cannot build an autonomous aviation system without resilient, high-bandwidth connectivity. Liquidity We ended Q4 with approximately $2 billion in liquidity. Operating in a capital-intensive sector, that matters. It positions us to fund what matters. Our team knows that every dollar we spend shortens the runway we have to build a generational company. We must continue to be ruthless about cutting anything that does not earn its place. My job is to drive execution: fly aircraft, deploy them in cities, complete certification, scale manufacturing, and deliver to the customers who are waiting. Thank you to our team, our partners, the government agencies, and our shareholders that all play a part in our success. Deep tech is extremely challenging, and you give us the ability to pursue it. I do not take your support for granted, and we will work every day to continue to earn it. Adam Goldstein Founder & Chief Executive Officer

&nbsp;&nbsp;&nbsp;&nbsp;operating expenses included a $114.7 million increase in non-cash stock-based compensation expense. ● Q4 2025 Operating Expenses increased by $59.9 million from Q3 2025 to $234.7 million primarily driven by $36.1 million increase in non-cash stock-based compensation expenses, and other spend related to growing headcount and our supply chain efforts. ● FY 2025 Net Loss increased by $81.4 million from FY 2024 to a loss of $618.2 million primarily driven by $219.9 million increase in operating expenses, offset by $107.4 million decrease in non-cash charges within other income (expense), net and $30.9 million increase in interest income, net. ● Q4 2025 Net Loss increased by $59.0 million from Q3 2025 to a loss of $188.9 million primarily driven by the $59.9 million increase in operating expenses as described above. Adjusted EBITDA ● Q4 2025 Adjusted EBITDA was a loss of $137.9 million, which is within the guidance range of $110 million - $140 million. The loss was a planned increase of $21.8 million over Q3 2025 mainly due to increase in people and vendor related expenses. ● FY 2025 Adjusted EBITDA Loss increased by $112.9 million over FY 2024 due to the investment in the development, test, certification and production activities for our aircraft as mentioned earlier. Q1 2026 Financial Estimates ● Archer's financial estimates for first quarter of 2026 are as follows: ○ Adjusted EBITDA to be a loss of $160 million to $180 million. We have not reconciled our Adjusted EBITDA estimates because certain items that impact non-GAAP metrics are uncertain or out of our control and cannot be reasonably predicted. In particular, stock-based compensation expense and change in fair value of warrants is impacted by the future fair market value of our common stock and warrants along with other factors, all of which are difficult to predict, subject to frequent change, or not within our control. The actual amount of these expenses during 2026 will have a significant impact on our future GAAP financial results. Accordingly, a reconciliation of non-GAAP metrics is not available without unreasonable effort.

&nbsp;&nbsp;&nbsp;&nbsp;Non-GAAP Financial Measures To supplement our consolidated financial results prepared in accordance with GAAP, we use the following non-GAAP financial measures: Non-GAAP total operating expenses and Adjusted EBITDA. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, these non-GAAP financial measures have no standardized meaning prescribed by GAAP and are not based on a comprehensive set of accounting rules or principles and many of the adjustments to the GAAP financial measures reflect the exclusion of items that are recurring and may be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures. We believe that the use of non-GAAP financial measures help us evaluate our business and financial performance, identify trends impacting our business, formulate business plans and financial projections, and make strategic decisions. We believe that disclosing non-GAAP financial measures to the readers of our financial statements provides useful supplemental data that, while not a substitute for GAAP financial measures, can offer insight in the review of our operating and financial results and enables investors to more fully understand our performance and cash trends by removing the effects of certain non-cash expenses and non-recurring items. We excluded items in the following general categories from one or more of our non-GAAP financial measures, certain of which are described below: STOCK-BASED COMPENSATION EXPENSE We exclude stock-based compensation expense, which is a non-cash expense, from these non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information on our operating results and enhances our ability and the ability of the investors to understand the impact of non-cash stock-based compensation expense on our operating results. WARRANT EXPENSE & GAINS OR LOSSES FROM REVALUATION OF WARRANTS Expense from our common stock warrants issued to Stellantis, which is recurring (but non-cash) and gains or losses from change in fair value of public and private warrants from revaluation will be reflected in our financial results for the foreseeable future. We exclude warrant expense and gains or losses from change in fair value for similar reasons to our stock-based compensation expense. ACQUISITION-RELATED EXPENSE We exclude cash expenses, including diligence, legal, advisory and other costs incurred with acquisitions, from these non-GAAP financial measures because we believe these transaction-specific expenses are inconsistent in amount and frequency and do not correlate to the operation of our business and excluding these provides meaningful supplemental information on our operating results and enhances our ability and the ability of the investors to understand the impact of non-recurring acquisition-related expense on our operating results. ###
