Space Exploration Technologies Corp. (SPCX): Flight 14 strengthens Goldman Sachs' long-term Starship thesis despite engine-related issues

Overview

This event-driven update assesses Starship Flight 14 and concludes that its operational milestones reinforce Goldman Sachs' existing long-term thesis for SpaceX. The firm retains its Buy rating and $220 target while highlighting engine reliability, heat-shield durability and tower-landing execution as central remaining milestones.

Core views

Goldman Sachs characterizes the 28 September Flight 14 as largely successful and as a positive proof point for Starship's long-term development path. Super Heavy Booster 21 and Starship 41 launched from Starbase, Texas at 8:48 a.m. EST. The flight achieved successful stage separation, broadly successful booster flip, boostback burn and soft landing, a successful single-Raptor orbital-insertion burn that placed Starship in orbit for the first time, deployment of 26 operational Starlink V3 satellites, and Starship's first successful deorbit burn, atmospheric re-entry, flip maneuver and soft landing. The report argues that these milestones validate hardware, flight-control software and system redundancies, supporting the company's ability to scale mass sent to orbit. The report nevertheless identifies engine performance as the principal issue ahead of Flight 15. One sea-level Raptor failed about 1 minute 16 seconds into ascent. During Booster 21's boostback burn, that engine and one additional engine did not re-ignite, leaving 31 of 33 engines available for re-entry and 11 of 13 inner-ring engines for the continued boostback burn. On Starship 41, one Raptor Vacuum engine shut down about 30 seconds early, requiring the other five engines to burn longer to maintain the suborbital trajectory. Caution around this issue led SpaceX to deorbit at the first checkpoint, shortening planned time in orbit. Goldman Sachs therefore expects future investor attention to center on operational milestones, engine reliability, heat-shield durability and execution of returning vehicles through tower landings. Goldman Sachs views Starship as a central vehicle for pursuing several potential multi-trillion-dollar opportunities over a five-plus-year horizon. The 26 deployed Starlink V3 satellites are presented as a meaningful capacity unlock and evidence that Starship can support the next generation of broadband, mobile and eventually orbital-compute satellite deployment. The firm also argues that SpaceX's dominant launch position, vehicle-development progress and continued Starship iteration since the first test launch in April 2023 underpin its competitive position across launch, connectivity and AI-related opportunities. The report's economic logic rests on vertical integration and improving reusability. Drawing an analogy to Falcon 9, Goldman Sachs expects internal vehicle development and eventual reusability improvements to reduce Starship's cost per kilogram. It views Flight 14's engine re-ignition, deorbit burn and landing performance as evidence that this cost and scaling pathway remains viable, although full reusability and rapid launch cadence have not yet been proven. Goldman Sachs reiterates Buy, makes no changes to operating estimates or its $220 12-month target, and describes the current risk/reward skew as positive at 2.5:1 over the next 12-plus months. The target is based on a sum-of-the-parts framework using 2029 segment estimates: 9.5x EV/Sales for Space, 24.0x EV/GAAP EBIT for Connectivity and 28.0x EV/GAAP EBIT for AI. Those values are discounted back 1.5 years at 12%, a CAPM-derived rate built from a 3% normalized 10-year risk-free rate, approximately 1.3 average beta and a 7% equity risk premium. At $145.47 as of 28 September 2026, the stated target implies 51.2% upside.

Analysis framework

Goldman Sachs first evaluates Flight 14's timeline and operational outcomes, balancing completed milestones against engine-related shortcomings. It then links launch execution to the longer-term strategy of increasing launch frequency, reusability, Starlink deployment and orbital-compute capacity, before maintaining its segment-based valuation and target price.

Methodology notes

• Valuation methodsSOTP (Sum-of-the-Parts) Valuation

  Sum-of-the-parts valuation using separate 2029 segment multiples for Space, Connectivity and AI

  The target values Space at 9.5x EV/Sales and Connectivity and AI at 24.0x and 28.0x EV/GAAP EBIT, respectively, then combines and discounts the segment values.

• Quantitative, Factor, and Portfolio TheoryCAPM (Capital Asset Pricing Model)

  CAPM-derived 12% discount rate

  The report derives its discount rate from a 3% risk-free rate, approximately 1.3 average beta and a 7% equity risk premium, then discounts valuation back 1.5 years.

• Competition & strategyEconomies of Scale and Learning Curve

  Vertical integration and reusability-driven launch-cost reduction

  The report argues that continued vehicle iteration, vertical integration and reusability should lower cost per kilogram and reinforce SpaceX's competitive position.

• Space Exploration Technologies Corp. (SPCX)

  Primary covered company; Flight 14 is viewed as supporting the company's long-term ability to scale Starship launches and satellite deployment.

  Strengths

  Dominant launch-industry position, vertical integration, successful Flight 14 orbital and re-entry milestones, and exposure to Space, Connectivity and AI opportunities.

  Weaknesses

  Flight 14 experienced engine outages, and full Starship reusability and rapid launch schedules remain unproven.

  Comparison

  Goldman Sachs compares Starship's intended cost-reduction path with Falcon 9's reusability and vertical-integration model.

  Risks

  Governance concentration, capital intensity and cash burn, dilution, launch competition, regulatory approvals, Starlink scaling needs, and execution risk in orbital compute.

Impact & implications

The report sees Flight 14 as reinforcing SpaceX's launch and reusability advantages and supporting the capacity expansion needed for Starlink broadband, mobile satellite services and future orbital compute. It also makes clear that future progress depends on solving engine reliability issues and demonstrating full reusability and rapid launch schedules.

Risks

• Governance and execution risk are concentrated in the founder and CEO, while related-party transactions involving associated entities could create conflicts.
• High capital intensity and cash burn may require sizable future fund raises, primarily assumed through debt, while stock grants or equity raises could dilute shareholders.
• The Space business faces commercial-launch competition, reliance on government contracts and licenses, possible launch allocation to internal uses, and lower profitability on fixed-price contracts.
• Connectivity depends on Starship launch-capacity growth that has not yet demonstrated full reusability or rapid cadence, as well as enterprise and government contract scaling, partners, spectrum and regulatory approvals.
• AI depends on unproven orbital data-center compute, demand and competition for AI models and subscriptions, launch capacity, third-party inputs including NVDA GPUs, and broader macroeconomic conditions.

What to watch

• Operational milestones in future Starship launches.
• Raptor engine reliability.
• Heat-shield durability.
• Execution of vehicle returns through tower landings.
• Progress toward full reusability and rapid launch schedules needed to support Starlink and orbital-compute deployment.
