Unusual Machines and Red Cat both filed quarterly revenue growth above 500 per cent on 6 August, at gross margins twice apart, while Kratos raised guidance on rockets rather than drones.

Key takeaway

Two drone makers grew above 500 per cent at gross margins twice apart.

Unusual Machines, which makes components certified under the National Defense Authorization Act, reported second-quarter revenue of $16.7 million on 6 August, up 687 per cent year on year and 106 per cent on the quarter, with gross margin recovering to 34.7 per cent⁠1. Headcount ran from 81 at the end of 2025 to 141 by the first quarter and 240 by the close of the second. On 12 August the company dismissed its small regional auditor and engaged Ernst & Young, recording no disagreements, which is the audit standard institutional investors and federal contracting officers look for before writing large cheques. Chief executive Allan Evans describes the third quarter as a deliberate pause to build capacity, so the growth rate is not a trend line.

Red Cat Holdings filed the same day with revenue of $20.2 million, up 527 per cent, at a gross margin of 16.1 per cent⁠2. Gross profit on that revenue came to about one dollar in six. Growth bought at that price is market share rather than profit, and it leaves less room to absorb an import bill that rises in September. Red Cat also confirmed completion of the Quaze Technologies wireless-recharging acquisition, still pending when the company raised capital in June, and confirmed that its Teal Drones subsidiary remains a finalist in the Pentagon's Gauntlet II build sprint.

One set of numbers cuts against the mood. Kratos reported unmanned-systems backlog of $374.6 million at the end of the second quarter, fractionally below the $375.4 million it held three months earlier, while lifting full-year group guidance to between $1.750 billion and $1.810 billion on 30.5 per cent growth driven by rockets and turbines⁠3. The company has taken 106,000 extra square feet in Oklahoma City for Valkyrie and Firejet production. Floor space went in; the drone order book behind it did not move.

Deep Analysis

In plain English

Three US drone companies reported very different results in early August. Unusual Machines and Red Cat Holdings, both small companies that sell drone parts and finished drones, saw sales more than quintuple compared with a year earlier, though their profit margins remain thin. Kratos, a larger, more established defence contractor, grew much more slowly in drones specifically, and its drone order backlog actually dipped slightly. Kratos still raised its overall guidance for the year, but on the strength of its rocket and turbine businesses rather than drones.

Deep Analysis
Root Causes

Small-cap drone makers are riding Pentagon volume-procurement programmes such as Gauntlet II , which order thousands of low-cost units on tight timelines, favouring firms that can scale production fast even at thin margins over primes built for fewer, higher-margin, exquisite platforms.

Unusual Machines' auditor change, filed the same week as its earnings, is a governance event distinct from the growth story: the 8-K gives no reason for the change beyond the Item 4.01 disclosure requirement, so it should not be read as confirmation of an accounting problem without further filings.

What could happen next?
  • Meaning

    Fast top-line growth at thin margins for the smallest drone makers signals a market still being won on volume and price, not yet on profitability.

  • Consequence

    Kratos's decision to lean on rockets and turbines for growth guidance suggests larger primes see drone-specific margins as less attractive than adjacent defence hardware right now.
