Executive Summary

We rate Planet Labs(PL) as OW(Overweight). It has passed the intersection of growth and profitability, achieving FY2026 revenue of $307.7M(+26% YoY) and its first annual FCF surplus of $57.7M. FACT Backlog of $900M(+79% YoY), RPO of $852M, and FY2027 guidance of $415-440M provide the highest level of revenue visibility in the industry. NVIDIA GPU-native AI engine and Google TPU orbit-mounted partnership are building a long-term technology moat.

We rate BlackSky(BKSY) as EW(Equal Weight). Gen-3 satellites (35cm VHR) and LeoStella vertical integration are premium competitive advantages, but FCF -$75M, 8.25% convertible bonds $160M, and Short Interest 20% suggest high execution risk. FACT P/S 8.7x is trading at a 3.6x discount compared to PL's 31x, and PSG ratio 0.36x (PL 0.79x) shows undervaluation relative to growth. OW conversion possible upon completion of 12 Gen-3 orbits + confirmation of FCF turning positive.

INFERENCE The Iran war (started in February 2026) is proving the tactical value of satellite information in actual combat, explosively expanding the sovereign satellite demand of NATO member states. However, the energy shock (Brent $120+/bbl) and DOGE-led NRO budget cuts (~30%) caused by the same war are acting as short-term headwinds.

Key Verdict

PL wins in 9 dimensions of scale, finance, and technology, making it suitable as a Core Position. BKSY wins in 3 dimensions of valuation, consensus upside, and dilution risk, making it of interest as a Speculative Position. Portfolio composition: PL (Core 70%) + BKSY (Speculative 30%).

Macro Environment

Late-Cycle Stagflationary Pause + Geopolitical Shock

FACT Fed Funds Rate maintained at 3.50-3.75% (March 2026 FOMC, 11-1 vote). Dot plot suggests one rate cut within 2026, but the timing of the cut is being delayed due to the energy shock from the Iran war (Brent $120+/bbl). CPI YoY 2.4% (February), Core PCE 3.06%, concerns about reigniting inflation are tying the Fed's hands. (Source: Fed FOMC Statement, BLS CPI Report — 2026-03-18/11)

FACT US FY2026 defense budget $1.01T (+13%), Space Force $39.9B, NIP+MIP intelligence $115.5B. However, led by DOGE, NRO's EOCL (commercial satellite imagery) program has received warnings of up to 30% cuts. (Source: DoD Budget, MeriTalk, Breaking Defense — 2025-08~2026-01)

NARRATIVE All NATO member states are expected to achieve 2% of GDP in defense spending by 2026 (first time ever). Pledge of 5% GDP target by 2035 at the 2025 Hague Summit. As the Iran war proves the value of commercial satellite information in actual combat, an asymmetric structure of budget cuts → budget restoration is being formed in the medium term.

Macro Signal: Short-Term Bearish / Mid-Term Bullish

NRO budget cuts + stagflation → short-term (1-3M) headwinds. Proving the satellite tactical value of the Iran war + increased NATO spending + congressional budget restoration → mid-term (3-6M) catalyst. The fact that the 10-year Treasury yield has stabilized at 4.10-4.25% limits the risk of further valuation compression.

Industry Analysis — Earth Observation Satellites

FACT The global EO market is growing from $7.1B in 2025 to $14.55B in 2035 (CAGR 8.3%), and the small satellite segment that BKSY and PL are focusing on is growing at twice the speed of the overall market with a CAGR of 15.9%. As of 2024, there are 1,200+ EO satellites in orbit and 61% of missions equipped with AI analysis tools. (Source: MarketsandMarkets, Mordor Intelligence — 2025)

Competitive Landscape

FACT Vantor (formerly Maxar) leads with 21.3% market share, followed by Airbus Defence. Planet Labs dominates the medium-resolution market with daily global coverage, while BlackSky is targeting the premium VHR + AI analysis niche. In the SAR market, ICEYE leads with 70+ satellites and has secured sovereign contracts with Germany (€1.7B), Poland (€200M), and the Netherlands (€158M).

Key Trends

NARRATIVE The center of profitability in the value chain is shifting from satellite manufacturing to data analysis/platforms. Government/defense accounts for 54-67% of the total market, with defense contracts driving short-term revenue. Long-term TAM expansion is determined by commercial demand such as agriculture, climate, and insurance. SpaceX Starship commercialization is expected to innovate launch costs to ~$100/kg, reducing the cost of satellite expansion.
