The call

Oshkosh Defense still runs on government contracts and old tooling advantages, but the AM General loss and tariff costs are eating into the numbers while it waits on a JLTV rebid.

Oshkosh Defense builds armored vehicles and trucks for the U.S. military and has deep roots in government contracting that are hard to replace because of security clearances and long-term supply relationships. The company lost its biggest contract (JLTV vehicles) to rival AM General in 2023, which created a $687 million hole in revenue, and now faces rising material costs from tariffs that jumped from $35 million to $200 million. The next 6 to 12 months will matter most: if Oshkosh wins back the Navy's JLTV business or its new autonomous weapons contract gains ground, the revenue gap shrinks and the company stabilizes; if it loses again and those bets fail, the pressure gets much worse.

Why
01
AI pressure: Anduril Industries autonomous ground systems. Anduril and similar autonomy shops are building unmanned ground platforms that could shrink demand for crewed trucks over time. Could AI do the core job? Unlikely.
02
Bigger players: AM General. AM General took the JLTV production contract away in 2023, leaving a roughly $687 million revenue hole as that work winds down. Could a giant copy it? No, they are blocked.
03
What protects it. ITAR clearances, government-owned tooling, and multi-year sustainment work through 2031 make it hard for a new vendor to just walk in.
What would change this call
Navy/USMC JLTV RFI decision (7,500 vehicles, 4,000 trailers) within 6-12 months. Shows whether Oshkosh regains lost ground from AM General or falls further behind.
Q2 2026 earnings on July 28, 2026, including any NGDV impairment charge. Shows whether EPS pressure and contract writedowns are worsening or stabilizing.
Tariff cost realization moving from $35M to a reported $200M over H2 2026. Shows whether Oshkosh can absorb or pass on rising input costs without margin loss.
Key numbers
  • Oshkosh Corp FY2025 revenue: $10.4 billion (2025-12-31)

Named risks
  • Loss of JLTV RFI recompete would extend AM General's hold on flagship program. Severity: high
  • Tariff costs projected to rise from $35M to $200M in 2026, pressuring margins. Severity: high
  • NGDV $135M deferred costs exceed estimated profits, possible impairment. Severity: medium
  • Access segment backlog down 30.4% signals cyclical construction weakness. Severity: medium
  • Stryker MCWS delivery delays, only 100 of 269 units delivered by end of 2025. Severity: low

Could AI replace Oshkosh Defense?
No, Oshkosh Defense is deploying AI itself rather than being displaced by it, fielding autonomous vehicles like ROGUE-Fires Block 2 ($92 million award, 2026-06-01) with partner Forterra to reduce crew requirements, not competing against outside AI firms.
