What they do
NN makes precision parts and devices for medical tools, cars, aircraft, and industrial equipment.
NN wins by making parts used where failure is expensive. If your surgical stapler, fuel system, or flight-control component fails, the cheap supplier was never actually cheap. That helps explain why customers still buy from a company with 2,600 employees across medical, automotive, and aerospace markets.

The products that matter
largest disclosed operating segment
Mobile Solutions
$242M shown · -12.3%
this is the biggest disclosed piece on the page, and it moved the wrong way. If your largest visible segment is down 12.3%, the turnaround case has to come from margin repair, mix improvement, or better results in areas not broken out here.
core watchpoint
second disclosed operating segment
Power Solutions
$180M shown · -4.8%
this segment also declined, just less sharply. That's the catch. A support segment is supposed to steady the story. Here, it is still slipping too. Less bad is not the same as good.
still shrinking
what really has to work
Operational improvement
18.5% gross margin · $49M adj. EBITDA
the real product here is execution. Adjusted gross margin improved to 18.5% from 10.4% three years ago, and adjusted EBITDA reached $49M. That's real progress. But with 4.3% operating margin and $192M of long-term debt, progress has to keep compounding. It cannot pause for long.
the real bet
Key numbers
$192M
long-term debt
That is the number towering over the story. A company with a $63M market cap owes about 3 times that in long-term debt.
$422M
annual revenue
This is the current sales base, and it fell 9.1% vs. prior year, so the business is still moving backward.
4.3%
operating margin
Operating margin → profit after running the business → so what: there is very little cushion if orders slip or costs rise.
$1.11
FY2024 EPS
EPS → profit per share → so what: the company is still expected to lose money for the full year.

What just happened
missed estimates
Latest Revenue hit $317M, but NN still posted a loss of -$0.72 per share.
Revenue jumped 206% vs. prior year in the latest quarter, but that did not translate into profits. The quieter fact is the annual business still did $422M of revenue, down 9.1% vs. prior year.

the number that mattered
$192M of long-term debt matters more than the quarter, because a 4.3% operating margin leaves little room to service mistakes.

What could go wrong
NNBR does not need a dramatic macro excuse to disappoint you. The core risk is simpler: too much debt, too little margin, and sales still moving backward.
med
balance sheet stress
long-term debt is $192M, or 75% of total capital, against a market cap around $63M. That's the capital structure telling you who has priority.
if operating performance slips, equity holders absorb the pain first.
med
revenue keeps shrinking
annual revenue declined 5.1% last year, FY25 revenue growth was -9.1%, Mobile Solutions fell 12.3%, and Power Solutions fell 4.8%. That's not one weak pocket. That's broad pressure.
if volume does not stabilize, margin gains start looking cosmetic instead of durable.
med
EBITDA stalls below the target range
management's 2026 adjusted EBITDA target is $50M–$60M versus $49M today. Here's what would change our mind on a recovery case: EBITDA failing to clear $50M while debt still sits near $192M.
that would mean the turnaround is running in place, not turning.
med
limited segment visibility keeps the market skeptical
the segment rows shown here add to $422M against a page-level revenue figure of $2B. When the operating picture is this incomplete, investors have less evidence to trust a recovery narrative.
thin disclosure raises the burden of proof. You need cleaner results, not just cleaner storytelling.
$192M of debt, 4.3% operating margin, and shrinking revenue is the combo that matters. If one leg improves, you have a turnaround setup. If none do, you have a value trap wearing industrial clothes.

Pay attention to
calendar
next earnings update
you want two things in the same release: revenue that stops sliding and EBITDA that moves above $49M. One without the other is only half a fix.
metric
adjusted EBITDA versus the $50M floor
management's 2026 range starts at $50M. If NNBR cannot clear that from a current base of $49M, the recovery case is running hard just to stay in place.
risk
debt staying louder than equity
$192M of long-term debt versus a $63M market cap is not subtle. Watch the balance sheet before you start paying for a happier multiple.
trend
whether segment declines keep easing
Mobile Solutions fell 12.3% and Power Solutions fell 4.8%. The first sign of a real turn is simple: those declines stop widening and start flattening.
Analyst rankings
short-term outlook
mixed
coverage is thin and conviction is thinner. in human-speak, there is no strong wall street consensus to hide behind.
risk profile
volatile
a 5 / 100 price stability score means this does not trade like a steady industrial name. If you own it, expect swings.
chart momentum
stock-specific
with a 52-week range of $1–$3, the chart is telling you sentiment changes quickly when the operating story moves even a little.
earnings predictability
40/100
results are hard to model cleanly. Thin margins, debt, and declining revenue will do that.
