Performance Analysis
Horizon Aircraft’s second quarter as a public company was defined by a deliberate step-up in R&D investment, with operating expenses nearly doubling year-to-date to $11 million, primarily driven by a surge in aircraft development spend. Administrative costs remained flat, highlighting disciplined overhead control even as technical teams expanded. R&D, or research and development, is critical in aerospace, as it drives prototype build, subsystem testing, and the lengthy certification process required for new aircraft programs.
Liquidity is a clear focus, with Horizon closing the quarter holding more than $24 million in cash—its highest balance to-date—after raising $11 million at an average price of $281 per share. This capital is earmarked for the X7 full-scale prototype, with management confident the current runway is sufficient to reach initial ground testing by early 2027. Cash used in operations rose to $5 million for the six-month period, reflecting the scaling development effort.
- R&D Acceleration: Operating costs nearly doubled, with R&D up from $0.7 million to $5.3 million YTD, underscoring the transition from concept to build phase.
- Balance Sheet Strength: $24 million in cash supports milestone delivery and provides leverage in partner negotiations.
- Non-Dilutive Funding: INSAT grant and warrant exercises supplement capital needs, reducing shareholder dilution risk.
The step-change in spend signals a move from early-stage development to tangible hardware assembly, but also raises the bar for execution as technical milestones and certification work intensify in the coming quarters.
Executive Commentary
"Our near-term goal is to complete the design and manufacture of the full-scale X-7 prototype by the end of 2026, with initial testing targeted for early 2027. It's a critical milestone and our top priority that underpins a future certification, customer engagement, and potential revenue opportunities."
Brandon Robinson, CEO
"We have significantly improved our liquidity position over the last quarter. We did close the quarter with more than $24 million in cash, by far our healthiest balance sheet ever. We always strive to be patient and careful with our fundraising activity, and we currently use a combination of the at-the-market program, non-dilutive funding, and warrant exercises."

Strategic Positioning
1. Hybrid X7 Architecture: All-Weather and Range Advantage
The X7’s hybrid electric-gas design delivers a clear operational edge, enabling self-recharging, independence from ground charging infrastructure, and flight in adverse weather. This is a direct response to the limitations of all-electric eVTOL, electric vertical takeoff and landing, platforms, which remain range and environment constrained. The X7 is targeting a 500-mile range and 250-mph cruise speed, aiming to disrupt both helicopter and short-haul fixed-wing markets.
2. OEM-Only Model: Focused Execution
Horizon is positioning itself strictly as an OEM, original equipment manufacturer, declining to operate air taxi services or build out infrastructure. This focus allows the company to concentrate resources on engineering, certification, and manufacturing, while targeting sales to established operators in commercial, cargo, medevac, and defense markets.
3. Strategic Partnerships and Ecosystem Leverage
Recent collaborations with Pratt & Whitney and Motion Applied (ex-McLaren) strengthen propulsion, power electronics, and systems integration capabilities. The $10.5 million INSAT grant for all-weather eVTOL development highlights government and industry validation, while non-dilutive funding reduces equity risk. Management is actively pursuing further strategic partners, especially in aerospace and defense, to accelerate development and de-risk scale-up.
4. Certification and Regulatory Navigation
Certification is a gating factor for commercialization. Horizon’s partnership with Certification Centre Canada and focus on Transport Canada, rather than the more crowded FAA process, may offer an efficiency edge. The company is already engaged in functional hazard analysis and certification basis work, seeking to leverage lessons from first-wave eVTOL programs now nearing approval.
Key Considerations
As Horizon enters a capital-intensive build and test phase, investors must weigh the company’s differentiated technology, operational discipline, and strategic flexibility against the inherent risks of aerospace development and certification.
Key Considerations:
- Hybrid-First Strategy: X7’s hybrid approach addresses real-world operator demands for range, speed, and all-weather reliability, setting it apart from all-electric competitors.
- Capital Efficiency and Non-Dilutive Funding: Grants and warrant exercises supplement cash, but continued discipline is needed as OPEX is expected to double again by next year.
- Partner Leverage: Collaborations with propulsion and systems leaders de-risk technical execution and may accelerate certification.
- Certification Pathway: Transport Canada focus and in-house expertise could streamline regulatory approval versus U.S.-centric peers.
Risks
Execution risk is rising as R&D spend and technical complexity increase, with multiple subsystem and integration challenges ahead. Certification delays, supply chain bottlenecks, or cost overruns could impact timelines and require additional capital. The company’s current cash runway is sufficient for the next twelve months, but any slippage in milestones or partner funding could pressure liquidity. Competitive response from established OEMs or faster-moving eVTOL peers may also compress Horizon’s first-mover advantage in hybrid design.
Forward Outlook
For Q3 and Q4 2026, Horizon expects:
- Continued ramp in operating expenses as headcount and prototype build accelerate
- Key technical milestones: subsystem integration, full airframe assembly by late summer/fall
For full-year 2026, management reaffirmed its milestone-driven plan:
- Completion of full-scale X7 prototype by year-end
- Initial ground testing in early 2027
Management emphasized ongoing partner discussions and a commitment to capital discipline, noting:
- Strategic partnerships are prioritized for technical depth and long-term value, not near-term headlines
- Certification progress and technical data from prototype testing will drive future revenue opportunities
Takeaways
Horizon Aircraft’s Q2 marks a decisive shift from early-stage development to full-scale hardware execution, with capital deployment and technical milestones now the primary investor focus.
- Prototype Build and Certification: The next 12 months are critical as the X7 moves from design to build, with certification groundwork already underway.
- Strategic Partner Announcements: Any deal with a major aerospace or defense player could unlock value and de-risk execution, but management is signaling patience and selectivity.
- Capital Burn and Milestone Discipline: OPEX will continue to rise, making milestone delivery and non-dilutive funding essential to avoid future dilution or financing risk.
Conclusion
With a robust cash position and a clear technical roadmap, Horizon Aircraft is entering the most consequential phase of its journey. Successful prototype assembly, certification progress, and strategic partner execution will determine whether the X7 can capitalize on its hybrid advantage and deliver on its disruptive promise.
