Financial Profile (FY2025)
| Metric | $mm |
|---|---|
| Revenue | 18,674 |
| Revenue growth | 33.2% |
| Adjusted EBITDA | 6,584 |
| Loss from operations | (2,589) |

Segment disclosure
| Segment | Revenue | Adj. EBITDA |
|---|---|---|
| Connectivity (Starlink) | 11,387 | 7,168 |
| Space / Launch | 4,086 | n/d |
| AI / xAI | 3,201 | (1,237) |
| Total | 18,674 |
Capex of $20,737mm exceeds revenue — the defining feature of the financial profile and the reason the DCF stays negative through 2028E.
Valuation
Segment sum-of-the-parts
| Segment | Revenue | Low | Base | High |
|---|---|---|---|---|
| Connectivity | 11,387 | 3.98x | 6.0x | 8.0x |
| Space / Launch | 4,086 | 6.0x | 11.3x | 15.0x |
| AI / xAI | 3,201 | 3.0x | 5.0x | 7.0x |

Discounted cash flow
| Assumption | Value |
|---|---|
| Discount rate | 12.0% |
| Terminal growth | 4.0% |
| Revenue growth | 35% tapering to 15% |
| EBITDA margin | 35% expanding to 45% |
| Capex / revenue | 111% tapering to 22.5% |
| $mm | |
|---|---|
| PV of forecast FCF | (25,345) |
| PV of terminal value | 33,543 |
| Implied enterprise value | 8,198 |
| Less: net debt | (61,741) |
| Implied equity value | 69,939 |
Free cash flow turns positive in 2029E as capex intensity normalises. Sensitivity across a 10–14% discount rate and 3–5% terminal growth gives a range of $59.0bn to $95.2bn.
Trading comparables
| Segment | Median EV / Revenue | Median EV / EBITDA |
|---|---|---|
| Connectivity | 3.98x | 10.5x |
| Launch / space infrastructure | 11.29x | n/m |
| Aerospace and defence | 2.92x | 19.2x |
AST SpaceMobile excluded from the connectivity median as an outlier. Launch EV/EBITDA is not meaningful — most comparables have negative EBITDA.
Pricing and Aftermarket
| Metric | IPO | Day 1 |
|---|---|---|
| Price | $135.00 | $160.95 |
| Equity value ($mm) | 1,776,492 | 2,117,973 |
| Enterprise value ($mm) | 1,714,751 | 2,056,232 |
| EV / Revenue | 91.8x | 110.1x |
Day-1 pop of 19.2%. Money left on the table: $14,417mm, calculated as shares offered times the difference between the Day-1 close and the offer price.
First eleven sessions
| Session | Close | vs IPO |
|---|---|---|
| Day 1 | $160.95 | +19.2% |
| Day 3 (peak) | $201.80 | +49.5% |
| Day 5 | $185.00 | +37.0% |
| Day 7 | $154.60 | +14.5% |
| Day 11 | $153.23 | +13.5% |
The stock held above the offer price throughout, peaking at +49.5% on Day 3 before retracing. The pattern suggests genuine demand at pricing followed by the market recalibrating around capex intensity and segment economics.
Valuation Summary
| Method | Equity value ($mm) | vs IPO |
|---|---|---|
| DCF (base) | 69,939 | (96.1%) |
| Segment SOTP (base) | 192,240 | (89.2%) |
| IPO pricing | 1,776,492 | — |
| Day-1 trading | 2,117,973 | +19.2% |
Conclusion. Every fundamentals-based method lands far below the offer price. The SOTP, built on disclosed FY2025 segment revenue, supports $141bn to $237bn. The DCF, constrained by capex exceeding revenue, supports $59bn to $95bn. The IPO priced at 91.8x revenue and traded to 110.1x on Day 1.
The gap is not explained by current financials. It reflects whatever the market assigns to Starlink terminal scale, Starship economics, defence and government programmes, AI infrastructure and scarcity value — none of which the disclosed segment data captures. The analysis is best read as sizing that gap rather than as a fair-value estimate.

Technology Stack
- Microsoft Excel
- PitchBook market data
- SEC EDGAR (S-1, 424B4)
- DCF and comparable company analysis
Skills Demonstrated
- IPO pricing and aftermarket performance analysis
- Sum-of-the-parts valuation across disclosed segments
- Discounted cash flow modelling
- Trading comparables selection and outlier treatment
- Equity capital markets analysis
- Multi-method valuation reconciliation
Limitations
- The implied multiples at pricing — 91.8x revenue and 260.4x EBITDA — sit far outside any observable comparable range. The diluted share count driving equity value should be verified against the final 424B4 before these figures are relied upon.
- Space and Launch segment EBITDA is not disclosed, so all three segments are valued on revenue multiples. This understates Connectivity, which carries a 63% segment EBITDA margin.
- The DCF applies a simplified tax on EBITDA rather than a full tax build, and does not model stock-based compensation, working capital seasonality or segment-level capex allocation.
- Terminal value represents more than 100% of DCF enterprise value because forecast-period free cash flow is negative. The DCF is therefore highly sensitive to terminal assumptions.
- Comparable companies span connectivity, launch and aerospace with materially different growth and margin profiles. No single set is a clean read.
- Aftermarket data covers eleven sessions only, well inside the lock-up and index-inclusion windows.
