On July 31 Hanwha Aerospace Co., Ltd. (KRX:012450) and Vertical Aerospace Group Ltd. signed a termination agreement, ending a contract to develop and supply electromechanical actuators and the tilting and blade pitch systems for Vertical's VX4 electric aircraft. The DART filing three days later gives the terminated value as ₩454,828,405,776 and the reason as a strategic decision by both parties, taken because market conditions and direction had changed against the project's original purpose.
The same paragraph notes that the two companies simultaneously signed a memorandum of understanding to keep cooperating on similar development and mass-production supply work. A binding four-year contract was replaced by a non-binding memorandum on the same day. That's the shape of the story, and the ₩455bn is the least important number in it.
The sequence is worth laying out because the headline figure compresses it. Hanwha Aerospace signed the original agreement on August 23, 2022, worth ₩219.2bn, covering electromechanical actuators for the VX4. In June 2023 the two firms added tilt and blade pitch systems through a memorandum of agreement, and an October 2023 revision folded those into the contract and took the total to ₩454.8bn.
Then almost three years of development, and a termination. Spread across the life of the programme, ₩455bn is roughly ₩114bn a year of contracted revenue, against a company that reported ₩15.04tn of revenue in the first half of 2026 alone. This was never going to move the income statement. It was a position in a market, not a business line.
One arithmetic note for anyone reading the English coverage. The won figure in the filing is fixed: the company states it converted the dollar contract value at ₩1,326.70 to the dollar, the rate on August 22, 2022, the day before the original signing. That works out to about $343m at the time. Press reports quoting roughly $319m are converting the same won number at today's weaker won. Both are right about their own arithmetic. The filing's ₩454.8bn is the figure to use.
Item 2 of the disclosure reports the terminated amount as 7.09% of revenue, and the footnote explains that "recent revenue" here means Hanwha Aerospace's FY2021 consolidated figure of ₩6,415,087,932,347. Korean termination disclosures reference the revenue base used when the original contract was filed, which for a 2022 agreement means 2021.
Since then this company has quadrupled. FY2025 consolidated revenue was ₩26.70tn, lifted both by the European artillery surge and by the consolidation of Hanwha Ocean. Measured against that, ₩454.8bn is 1.70%.
So a reader who takes 7.09% at face value is overstating the impact by a factor of four. That's not the company being misleading; it's a disclosure rule doing what it was designed to do, anchored to the moment the commitment was made. It's also a good illustration of why Korean filings reward reading the footnote rather than the headline field.
The filing's language is scrupulously mutual. Both parties performed their obligations faithfully, it says, and both agreed to terminate on strategic grounds.
Trade coverage reports something more specific: Vertical has moved to a different actuator supplier for the VX4. If the customer has already sourced the same components elsewhere, the programme did not die. The supplier withdrew from it. At least one Korean outlet went further and framed the move as Hanwha winding down its urban air mobility business, though that's a characterisation rather than something the company has filed.
The direction is legible either way. A company that expected eVTOL to be a real segment in five years does not swap a signed development-and-supply contract for an MOU about possible future cooperation. It renegotiates the milestones and waits.
Set aside the optics and the decision looks sound.
Urban air mobility has slipped. Certification programmes across the sector have taken longer than the schedules published in 2021 and 2022, and the commercial fleets that were supposed to be flying by now are not. A supplier committed to a development programme in that environment carries engineering cost against revenue that keeps moving right, and the actuator work here was custom rather than a catalogue part.
Meanwhile the opportunity cost has changed beyond recognition. In 2022 Hanwha Aerospace was a ₩6.5tn-revenue company looking for growth vectors. Today it has a European artillery order book, a consolidated shipbuilder, and an active pursuit of a US shipyard, and its operating income has gone from ₩377bn in FY2022 to ₩3.09tn in FY2025. Engineering capacity spent on tilt-rotor actuators for an aircraft that has not been certified is capacity not spent on things customers are queuing for.
The MOU costs nothing and preserves the relationship. If eVTOL becomes real in the 2030s, Hanwha has a document and a working history rather than a lawsuit.
Two counters deserve a hearing.
The first is about technology rather than revenue. Electromechanical actuators for a tilting rotor are hard, and the development work has spillover into conventional aerospace, where Hanwha Aerospace already supplies engine components. Walking away mid-programme risks losing the team and the accumulated know-how, and the company has not disclosed what happens to either. Whether the capability is retained or dissolved is genuinely unknown from the filings.
The second is about credibility as a partner. A supplier that exits a flagship development contract three years in, however mutually, is a supplier that future customers will price differently. In defence that matters less, because the buyers are governments with limited alternatives. In civil aerospace, where Hanwha wants to grow its engine parts business, reputations for seeing programmes through are worth something.
There's also the question of whether ₩455bn of contracted revenue disappearing from the order book matters at the margin. It does not move FY2026, since the work was spread over years and much of it was already recognised or never started. But the backlog disclosure in the next annual report will be lower than it would have been, and backlog is the number defence investors watch.
The FY2026 annual report, due next March, and specifically the segment disclosure for the aircraft engine and components business. If revenue and margin there step up, the engineering resource went somewhere useful. If the segment is flat and the company simply stops mentioning urban air mobility, the honest reading is that a four-year programme was written off and the MOU was the exit door.
The nearer marker is whether any further termination or amendment filings follow. This disclosure covers the contracts announced on August 23, 2022 and October 18, 2023. If the company has other advanced air mobility commitments, they haven't been terminated yet, and their absence from the filings is currently the only evidence about how deep the retreat goes.
