What Are Archer Aviation and Joby Aviation, and Why Do eVTOL Stocks Matter?
Archer Aviation and Joby Aviation both emerged from the broader push toward sustainable aviation, though their origins and approaches differ substantially. Joby Aviation, founded in 2009 by JoeBen Bevirt, represents the longer-standing player with over a decade of aircraft development and approximately $2 billion in total capital raised prior to its SPAC merger. The company acquired Uber Elevate in 2020, gaining valuable software assets and airspace management technology.
Archer Aviation, founded in 2018 by Brett Adcock and Adam Goldstein, took a more aggressive timeline approach, leveraging experienced aerospace talent recruited from established manufacturers and pursuing rapid iteration cycles. eVTOL stocks matter because they represent ground-floor investment opportunities in what could become essential transportation infrastructure. Unlike traditional aerospace investments in mature companies like Boeing or Airbus, eVTOL pure-plays offer exposure to exponential growth potential—but also carry substantial execution risk. The total addressable market extends beyond passenger transport to include cargo delivery, emergency medical services, and defense applications, each representing multi-billion-dollar opportunities.
- **Joby Aviation (NYSE: JOBY)** operates as a vertically integrated manufacturer with in-house battery development and manufacturing facilities in Marina, California
- **Archer Aviation (NYSE: ACHR)** pursues a partnership-heavy model with United Airlines providing up to $1 billion in conditional purchase commitments and Stellantis supporting manufacturing expertise
- **Market positioning** differs significantly: Joby targets longer-range regional flights up to 150 miles, while Archer focuses on shorter urban routes around 60 miles
Aircraft Technology and Performance Specifications Compared
The technical specifications of each company’s aircraft reveal fundamentally different design philosophies that will influence operational capabilities and market positioning. Joby’s S4 aircraft features a distinctive tilting rotor design with six propellers that rotate from vertical to horizontal orientation during flight transition. This configuration enables a maximum range of approximately 150 miles, cruise speeds up to 200 mph, and payload capacity for one pilot plus four passengers. The S4 has accumulated over 1,000 flight test hours, more than any other eVTOL in the certification process.
Archer’s Midnight aircraft employs a different architecture with 12 separate rotors: six dedicated lift rotors for vertical flight and six tilt rotors for forward cruise. This configuration prioritizes redundancy and faster turnaround times between flights, targeting the high-frequency urban shuttle market. Midnight offers a range of approximately 60 miles, cruise speeds around 150 mph, and capacity for one pilot plus four passengers. The design philosophy emphasizes rapid passenger throughput over maximum range.
- **Battery technology** represents a key differentiator: Joby develops proprietary cells in-house, while Archer partners with external suppliers, creating different risk and potential reward profiles
- **Noise signatures** vary significantly—Joby claims 45 dBA at 500 meters during flyover, roughly equivalent to normal conversation, while Archer targets similarly low levels but with different acoustic characteristics
- **Certification basis** both companies pursue FAA Part 135 air carrier certification, but their aircraft fall under different airworthiness standards affecting approval timelines
FAA Certification Progress and Regulatory Milestones
Regulatory approval represents the single most important near-term catalyst for both stocks, as commercial operations cannot commence without FAA type certification. Joby has consistently led the certification race, achieving several milestone firsts including the first eVTOL to receive a signed G-1 certification basis from the FAA and the first to complete the Stage 4 conformity review. The company expects to receive type certification in 2025, positioning it potentially as the first certified eVTOL in the United States.
Archer has made substantial certification progress despite its later start, receiving its own G-1 certification basis in 2023 and completing numerous ground and flight tests required for approval. The company targets certification in 2025, though most industry observers expect Joby to cross the finish line first. Both companies participate in the FAA’s ongoing rulemaking process that will establish operational standards for the entire industry.
- **Type certification** involves demonstrating compliance with thousands of individual requirements covering structures, systems, powerplant, and operational characteristics
- **Production certification** follows type certification and authorizes manufacturing at scale—both companies are pursuing these certifications in parallel to accelerate time to market
- **International certification** through EASA (European Union), CAAC (China), and other regulators represents additional market access, with both companies engaging in simultaneous approval processes
Financial Position and Cash Runway for eVTOL Investors
Understanding the financial health of each company proves essential for evaluating investment risk, as neither generates revenue and both consume significant capital. As of late 2024, Joby Aviation maintained approximately $900 million in cash and equivalents with quarterly burn rates around $100-120 million, suggesting runway into 2026 without additional capital raises. The company’s vertically integrated model requires higher capital expenditure but potentially offers better unit economics at scale.
Archer Aviation reported similar cash positions around $500 million with lower quarterly burn rates near $80-100 million, though the company has demonstrated willingness to raise additional capital through equity offerings. Archer’s partnership model reduces certain capital requirements but introduces dependencies on third parties. Both companies will likely require additional funding before achieving profitability, making dilution risk a meaningful consideration.
- **Revenue projections** remain speculative but both companies have published aggressive targets: Archer projects $2.2 billion in revenue by 2028, while Joby forecasts similar scale
- **Order backlogs** provide some visibility—Archer claims over $6 billion in conditional orders primarily from United Airlines, while Joby reports approximately $2.5 billion including commitments from Delta Air Lines
- **Break-even timelines** extend beyond 2027 for both companies under optimistic scenarios, requiring investors to maintain long time horizons
Partnership Ecosystems and Strategic Alliances
The partner networks surrounding each company significantly influence their competitive positioning and probability of commercial success. Archer Aviation benefits from particularly strong strategic relationships with United Airlines and Stellantis. United has invested over $100 million directly and committed to conditional aircraft purchases worth up to $1 billion, while also planning to operate Archer aircraft on routes connecting airports with city centers.
Stellantis provides manufacturing expertise through a joint venture arrangement that could leverage automotive production techniques to achieve aerospace-grade quality at significantly lower costs. Joby Aviation’s partnership strategy emphasizes different strengths, including a $400 million investment from Toyota that brings manufacturing expertise and supply chain optimization capabilities. The Delta Air Lines partnership announced in 2022 provides similar airline operator support to Archer’s United relationship, though with somewhat smaller initial commitments. Joby’s acquisition of Uber Elevate delivered software assets for multimodal transportation integration that could prove valuable as services launch.
- **Manufacturing partnerships** matter enormously: Archer’s Stellantis relationship targets 650 aircraft annually from their Georgia facility, while Joby pursues in-house manufacturing in California
- **Airline relationships** provide route planning, customer acquisition channels, and operational expertise neither company possesses independently
- **Defense contracts** represent additional revenue potential—Joby has secured over $130 million in contracts from the U.S. Department of Defense, while Archer recently received its first defense contract
Market Valuations and Stock Performance Outlook
Current market valuations reflect both the enormous potential and significant uncertainty surrounding eVTOL commercialization. Joby Aviation trades at an enterprise value of approximately $4-5 billion depending on recent price movements, representing roughly 2x projected 2028 revenue under management guidance. Archer Aviation commands a similar valuation range despite later market entry, suggesting investors view both companies as having comparable risk-adjusted potential.
Stock price volatility in both names has been substantial since their respective SPAC mergers, with each experiencing drawdowns exceeding 70% from peak values before recovering partially. This volatility will likely continue until certification milestones provide greater visibility into commercial launch timing. Institutional ownership has grown in both stocks, with notable positions from growth-oriented funds providing some validation of the investment thesis.
How to Prepare
- **Review FAA certification documentation** by visiting the FAA’s online docket system and searching for each company’s certification project—this provides objective evidence of regulatory progress beyond company press releases and reveals potential issues or delays
- **Analyze quarterly financial filings** through SEC EDGAR to understand cash burn rates, runway calculations, and management discussion of risks—pay particular attention to going concern language and capital raise plans
- **Assess partnership quality** by examining the specific terms of airline and manufacturing agreements disclosed in filings, distinguishing between binding commitments and non-binding letters of intent or conditional orders
- **Monitor flight test progress** through company announcements and FAA records, as accumulated flight hours correlate with certification readiness and reveal technical challenges when test campaigns pause or reset
- **Compare management experience** by reviewing executive backgrounds for relevant aerospace certification experience, as this process-intensive phase rewards deep regulatory expertise over entrepreneurial vision alone
How to Apply This
- **Size positions appropriately** for pre-revenue companies by limiting eVTOL exposure to a small percentage of total portfolio value—typically 1-5% for risk-tolerant investors—given the binary outcome distribution between massive success and total loss
- **Consider diversified exposure** by investing in both Archer and Joby rather than selecting a single winner, as the market likely supports multiple successful operators and specific certification outcomes remain unpredictable
- **Establish monitoring triggers** such as certification milestone dates, quarterly cash updates, and major partnership announcements that would prompt position review rather than reacting to daily price movements
- **Define exit criteria** in advance including both upside targets where partial profits make sense and downside stops that limit maximum loss, recognizing that thesis changes rather than price movements should drive decisions
Expert Tips
- **Watch the flight test campaigns** closely—when either company pauses testing for extended periods or returns to earlier test phases, this often signals technical issues not yet disclosed publicly and typically precedes stock price weakness
- **Certification timing estimates** from management consistently prove optimistic across the entire eVTOL industry; sophisticated investors apply 12-18 month delays to stated timelines when building financial models
- **Manufacturing ramp assumptions** deserve skepticism, as aerospace production at automotive rates has never been achieved; Archer’s Stellantis partnership provides the most credible path but remains unproven
- **Consider the infrastructure buildout** required for operations—vertiport construction, charging networks, and air traffic management systems represent ecosystem dependencies that could delay revenue generation even after certification
- **International markets** may generate revenue before U.S. operations, as regulators in UAE, Saudi Arabia, and other jurisdictions have demonstrated faster approval willingness; track each company’s international certification efforts
Conclusion
The choice between Archer Aviation and Joby Aviation ultimately depends on individual investor priorities regarding timeline, risk tolerance, and conviction in specific strategic approaches. Joby offers first-mover advantages in certification, longer-range capability, and vertically integrated technology development, while Archer provides stronger airline partnership commitments, manufacturing scale potential through Stellantis, and a business model focused on high-frequency urban routes. Both companies face substantial execution risk with no guarantee of commercial success, yet both also offer exposure to a transformative transportation technology with trillion-dollar market potential.
Investors should recognize that this sector remains highly speculative and position sizing matters more than stock selection for most portfolios. The companies compete less directly than they might appear, as the urban air mobility market likely supports multiple successful operators serving different route profiles and geographic markets. Those with strong conviction in the space might reasonably own both stocks, while more conservative investors might wait for certification milestones to reduce uncertainty before initiating positions. Regardless of approach, the coming 24 months will prove decisive as both companies navigate the final phases of certification and prepare for commercial operations.
