1. Company Snapshot

2. Bull vs Bear Case

Bull Case

• Technology milestones are landing: the Cobra ceramic-separator process was baselined into production in June 2025, QSE-5 B-sample cells shipped to Volkswagen, the Eagle pilot line was inaugurated on 4 February 2026 and a QSE-5-powered Ducati race bike has run in public.
• Capital-light licensing model: rather than building gigafactories, QuantumScape licenses its cell design and separator process to PowerCo (up to 85 GWh a year of licensed capacity after the July 2025 amendment, with up to $130.7m of milestone funding), keeping FY2026 capex guidance at just $27m to $37m.
• Second OEM validates the approach: Honda signed a multi-year joint research agreement on 18 June 2026 after completing its own benchmarking phase, adding motorcycles and power equipment as target markets alongside Volkswagen's EVs.
• Runway into 2029: $859m of cash and marketable securities at 30 June 2026 against an FY2026 adjusted EBITDA loss guide of $250m to $275m, with cumulative customer billings reaching $40m by August 2026, means there is no near-term financing cliff.

Bear Case

• Still no revenue after 15 years: the company has recognised $0 of GAAP revenue in every year since inception and management frames 2027 as the earliest window for meaningful commercial output; the accumulated deficit is $4.0bn.
• Dilution is the funding model: at-the-market share sales raised $264.2m in FY2025 and $128.5m in FY2024, and the diluted share count has grown from 409.5m in FY2021 to 617.1m in Q2 2026, so any future capital raise lands on a share price already down ~96% from its 2020 high.
• Dependence on PowerCo: the FY2025 10-K states the PowerCo collaboration is the only agreement with the intent to commercialise the technology; the royalty-bearing IP licence is still contingent on technical milestones and has not been signed.
• Competition is well funded: Toyota, Samsung SDI, CATL and Factorial are all pursuing solid-state cells with far larger balance sheets, and continued cost declines in conventional lithium-ion narrow the performance premium QuantumScape needs to command.
• Market has lost patience: the shares fell 31% in July 2026 and 14% in a single session after Q2 results despite an EPS beat, with coverage citing softening EV demand and unease about the pivot to a pure-licensing strategy.

3. Business Segments

QuantumScape operates as a single segment and has no GAAP revenue. The table lists the activities that generate cash inflows or contracted value today; percentages of revenue are not applicable because revenue is zero.

4. Business Model & Moat

How it intends to make money. QuantumScape is moving from a build-and-sell model to a licensing model. Under the PowerCo arrangement, Volkswagen's battery company would manufacture QSE-5-based cells in its own plants using QuantumScape's separator and cell design, paying a royalty prepayment and per-unit royalties once the IP licence is executed. Until then, cash inflows come from milestone payments ("customer billings", $19.5m in FY2025 and $21.8m in H1 2026) that are recorded as customer deposits rather than revenue. The Eagle Line exists to prove that the Cobra separator process can produce cells at scale and consistent quality, which is the gating item for the licence.

Where the moat lies. The core intellectual property is the anhydrous ceramic solid electrolyte separator, which enables an anode-free lithium-metal cell (lithium plates directly on the current collector during the first charge). If it works at scale, the design promises higher energy density, faster charging and improved safety than lithium-ion, and the ceramic chemistry is protected by a patent estate built over fifteen years. The Cobra process, which cuts separator heat-treatment time and footprint dramatically versus the prior Raptor process, is the manufacturing know-how that a licensee cannot easily reproduce.

Cost structure and cash burn. Operating expenses run at roughly $105m to $110m a quarter, of which about $13m to $20m is depreciation and $45m to $50m is stock-based compensation. Adjusted EBITDA loss was $252.3m in FY2025 and is guided to $250m to $275m for FY2026. Capex has fallen from $158.8m in FY2022 to $36.3m in FY2025 and a guided $27m to $37m in FY2026 as the company stops building its own volume capacity.

Funding. The company has financed itself through the 2020 SPAC merger, follow-on offerings and at-the-market equity programmes ($128.5m in FY2024, $264.2m in FY2025). With $859m of liquidity at 30 June 2026 management says the runway extends into 2029, but every year of delay pushes the eventual royalty stream further out and raises the odds of another equity raise.

5. Financial Health

All figures are from QuantumScape's 10-K and 10-Q filings and the SEC XBRL companyfacts dataset. The company has recognised no GAAP revenue in any period. It reports no adjusted EPS; the adjusted column therefore repeats the GAAP figure†. Its only non-GAAP profit measure is adjusted EBITDA, quoted in the notes. QuantumScape has no funded debt; the only interest-bearing obligations are finance leases (non-current finance-lease liability $26.3m at 30 June 2026)‡.

† QuantumScape publishes no adjusted EPS; GAAP diluted EPS is repeated. Adjusted EBITDA losses were $249.2m (FY2023), $285.0m (FY2024) and $252.3m (FY2025). GAAP net losses were $46.0m (FY2021, flattered by non-cash gains on warrant revaluation against an operating loss of $215.3m), $411.9m (FY2022), $445.1m (FY2023), $477.9m (FY2024) and $435.1m (FY2025). ‡ No borrowings; finance-lease liabilities only ($39.4m non-current at end-2021 declining to $28.3m at end-2025).

Quarterly detail, most recent first. The FY2025 row is the audited full-year total.

Cash flow and liquidity. Operating cash outflow was $127.9m (FY2021), $218.0m (FY2022), $240.0m (FY2023), $274.6m (FY2024) and $242.5m (FY2025), with $116.3m consumed in the first half of 2026. Capital expenditure fell from $127.2m and $158.8m in FY2021 and FY2022 to $84.6m, $62.2m and $36.3m in the following three years, and $14.6m in H1 2026. Year-end cash and marketable securities were $1,447.7m (2021), $1,061.7m (2022), $1,070.8m (2023), $910.8m (2024) and $970.8m (2025), then $859.0m at 30 June 2026. On a trailing-twelve-month basis to 30 June 2026 the operating loss was $440.7m, depreciation and amortisation $55.9m, operating cash outflow $236.1m and capex $36.5m. The diluted share count averaged 617.1m in Q2 2026 versus 409.5m in FY2021; because the company is loss-making, the diluted count understates the true dilutive overhang from warrants and awards, which are antidilutive and excluded.

6. Valuation Metrics

Raw metrics, September 2026. Not opinions on whether the stock is cheap or expensive.

Price basis: $5.48 close on 4 September 2026. Share count ~619.1m (Class A 587.2m plus Class B 31.9m per the Q2 2026 10-Q cover, 17 July 2026). Earnings-based multiples are not meaningful for a pre-revenue, loss-making company; the components are shown so readers can see why.

7. What Are They Building

QSE-5 and the anode-free architecture. QSE-5 is QuantumScape's first commercial cell design: a roughly 5 amp-hour lithium-metal cell with no manufactured anode, using a proprietary ceramic separator to block dendrites. B-sample cells built with the Cobra separator process shipped to Volkswagen in 2025, and the company's 2026 goal is to demonstrate that the Eagle Line can produce QSE-5 cells at scale with consistent quality.

Cobra separator process and the Eagle Line. Cobra is the heat-treatment process that replaced Raptor in June 2025, cutting cycle time and equipment footprint by an order of magnitude according to the company. The Eagle Line, the pilot production line in San Jose, was formally inaugurated on 4 February 2026 and is the reference design PowerCo would replicate. Ceramics production is supported by partnerships with Murata Manufacturing and Corning.

PowerCo industrialisation. The July 2024 collaboration agreement and the 17 July 2025 amendment give PowerCo rights to up to 85 GWh of annual licensed capacity and provide up to $130.7m of milestone-based funding to QuantumScape. The next contractual step is the royalty-bearing IP licence, which depends on cells meeting agreed technical targets; management has said it expects PowerCo to begin low-volume production from a pilot line before scaling.

New applications. Honda's joint research agreement (18 June 2026) covers EVs, motorcycles and power equipment. The Ducati V21L race bike, first shown at IAA Mobility in September 2025, is the public demonstrator for two-wheel applications. JB Straubel, the Redwood Materials founder and former Tesla CTO, joined the Strategic Advisory Board on 3 June 2026.

8. Peer Comparison

Market caps are as of the 4 September 2026 close. Metrics are the latest reported by each company.

9. Insider Activity

Insider activity in 2026 has been small in dollar terms and dominated by tax-withholding sales on vesting restricted stock units and pre-scheduled 10b5-1 plan sales. CEO Siva Sivaram (filed under his legal name Srinivasan Sivaram) disposed of 81,752 shares on 18 August 2026 to cover taxes on an RSU vest; CFO Kevin Hettrich made small 10b5-1 sales in June and July and a tax-withholding sale in August; co-founder and CTO Tim Holme's family trust sold its remaining Class A shares on 21 August 2026 for $76,465 while retaining Class B stock.

10. Key Risks

• Liquidity and dilution: the company is pre-revenue and burns roughly $240m of operating cash a year; $859m of liquidity funds operations into 2029 only if spending stays on plan, and any slippage in the PowerCo licence would require further at-the-market equity sales at a share price already down ~96% from its peak.
• Commercialisation timing: QuantumScape has repeatedly pushed out volume production; the FY2025 10-K warns of significant delays and technical challenges in replicating early sample-cell performance at scale, and $26.6m of equipment was written off in FY2025 as obsolete.
• Single-partner dependence: the PowerCo collaboration is described in the 10-K as the only agreement with intent to commercialise; the royalty-bearing IP licence has not been signed, and Volkswagen, as largest shareholder with two board designees, has considerable influence over terms.
• Strategic-pivot execution: the shift to a pure-licensing model lowers capex but makes QuantumScape's economics depend entirely on partners' factory build-outs and EV demand, both of which are outside its control; investors marked the shares down 31% in July 2026 as this became clearer.
• Competitive displacement: Toyota, Samsung SDI, CATL, Factorial and others are targeting solid-state cells in the same 2027 to 2030 window, while falling lithium-ion and LFP costs raise the bar QSE-5 must clear on cost per kilowatt-hour.
• EV demand and policy: weakening Western EV demand, tariff changes and the withdrawal of purchase incentives reduce OEM urgency to fund next-generation chemistries and were cited in coverage of the July 2026 selloff.
• Short-seller pressure and volatility: ~19% of the float is sold short with four days to cover, so the stock moves violently on headlines in both directions, complicating any future equity raise.

11. Recent Developments

• 02 Sep 2026 — "Make-or-break 2027" framing gains traction. Coverage marking the shares as ~96% below their all-time high framed 2027 as the decisive year for commercial cell output, reflecting the market's compressed patience.
• 21 Aug 2026 — CTO Tim Holme's trust exits its Class A stake. The trust sold its remaining 12,723 Class A shares for $76,465 under a 10b5-1 plan adopted in June 2025, retaining about 1.2m Class B shares and derivatives; Holme also holds roughly 1.7m shares directly.
• 18 Aug 2026 — Executives file tax-withholding sales. CEO Siva Sivaram (81,752 shares), CFO Kevin Hettrich (31,095) and Chief Legal Officer Michael McCarthy (25,709) each disposed of shares at $5.74 to cover taxes on vesting RSUs.

• 22 Jul 2026 — Q2 2026 results. Net loss narrowed to $98.2m (-$0.16 per share) with an adjusted EBITDA loss of $64.2m; customer billings were $10.8m in the quarter and $21.8m year to date; FY2026 capex guidance was cut to $27m to $37m from $40m to $60m while the adjusted EBITDA loss guide of $250m to $275m was reiterated.
• 18 Jun 2026 — Honda joint research agreement. Honda R&D signed a multi-year agreement after completing its own evaluation of QuantumScape's cells, making Honda the second major OEM partner after Volkswagen and extending the target market to motorcycles and power equipment.
• 03 Jun 2026 — JB Straubel joins Strategic Advisory Board. The Redwood Materials founder and former Tesla CTO joined the advisory board; director Ross Niebergall received his annual RSU award the same day.
• 22 Apr 2026 — Q1 2026 results. GAAP net loss $100.8m (-$0.16 per share), adjusted EBITDA loss $63.2m, capex $10.0m and liquidity of $904.7m; customer billings of $11.0m in the quarter.

12. Key Dates

• Expected 21 Oct 2026 — Q3 2026 results and shareholder letter. Market-data calendars list 21 October; other trackers show 22 or 28 October. QuantumScape typically confirms the date about two weeks in advance.
• Expected Feb 2027 — Q4 and full-year 2026 results with FY2027 guidance for adjusted EBITDA and capex, followed by the FY2026 10-K.
• Expected 2027 — Management's stated window for PowerCo pilot-line output and the first meaningful commercial cell volumes; execution of the royalty-bearing IP licence remains milestone-dependent.
• TBC — Announcement of any further OEM or licensing agreements beyond PowerCo and Honda, and any PowerCo milestone payments under the $130.7m funding amendment.

Undated items to watch include Eagle Line output and yield disclosures in each shareholder letter, and any resumption of at-the-market share sales.
