| Top risks | No full-scale Otter has flown — every government contract listed ($37.5M, $52.5M, $54.5M) is for a vehicle class with zero flight history; only sub-scale Pups have flown.; Docking with uncooperative targets is demonstrably hard — Otter Pup 1 suffered an anomaly, and Otter Pup 2 lost its original docking partner mid-mission. | Helios has never flown — roughly $1B raised and a $4.26B valuation are underwritten by a vehicle with zero flight history, and the target date has already slipped from 2026 to 2027.; Customer concentration in national security — TacRS and NSSL revenue is politically driven and schedule-fragile. | Effectively a single-customer company — every listed contract is US Space Force or SDA, with no meaningful commercial revenue to offset a budget shift.; Capital intensity with undisclosed valuation — $650M raised in one round plus $50M debt and headcount quadrupling to 1,000 by 2028, with no disclosed valuation or revenue. |
| Next catalyst | Otter Pup 2 docking attempt with Gilmour Space's ElaraSat (2026) | First Helios flight (2027) | Kronos delivery (2026-2027) |
