Why Is NN, Inc. Stock Down Today?

NN, Inc. (NNBR) reported a Q2 2026 quarter that reads as a clean beat-and-raise: net sales of $128.7 million, up 19.3% year-over-year, adjusted EBITDA up 36.1% to $17.9 million, and adjusted net income of $5.5 million ($0.11 per diluted share). The GAAP net loss narrowed to $2.3 million. Full-year sales guidance was raised to $460-470 million, from $450-470 million, above the $464.86 million analysts had modeled.

NN is a diversified industrial manufacturer of high-precision bearing, metal, and plastic and rubber components serving data-center, medical, defense, and mobility customers. CEO Harold Bevis said the company delivered strong financial performance in the second quarter with record results in many areas. The company's 5 Pillar growth initiative delivered roughly $40 million in new business wins during the quarter across its Data Center, Medical, and Defense end markets, and NN says it is on pace to install about 50 new machines in its data-center business in 2026 against a pipeline worth more than $50 million.

NN also closed an $89 million preferred-stock refinancing shortly after the quarter ended, bringing in new institutional investors. Nothing in this release points to a negative catalyst — this is a straightforward improving-fundamentals story from a company leaning into data-center and defense-related demand.
