$MPTI is a tiny defense supplier sitting at a real chokepoint.

Mtron makes precision RF filters and oscillators that go inside missiles, radars, and EW systems. Not flashy, but absolutely essential. If the munition needs guidance, these parts matter.

Why it is interesting:

$52M revenue

44% gross margins

Zero debt

Profitable

All US manufactured

The key point is qualification. Once a component gets designed into a missile program, switching is painful, slow, and expensive. That can lock suppliers in for 20+ years.

If air defense production has to ramp, already qualified suppliers become critical infrastructure. That is where Mtron could matter a lot more than its size suggests.

Prime contractors moving from 12 month Purchase Orders to a 24 month, $24M commitment is not business as usual. It signals sustained demand ahead.

Downside seems limited:

Profitable business, no debt, insider buying, modest multiple.

Upside is the real story:

If munition demand accelerates, this could stop looking like a $52M revenue company very quickly.

Underfollowed. Low market cap. Fully capitalized.
Right at the intersection of defense spending and production reality.
