[One Stop Systems](https://www.bullished.co/tag/oss/) shares fell 7.54% to $6.25 in Wednesday trading, as of 3:15 p.m. ET, erasing about $13 million in market value, even after the company [reported third-quarter revenue of $12.6 million](https://finance.yahoo.com/markets/stocks/articles/one-stop-systems-inc-oss-123004484.html?.tsrc=rss&ref=bullished.co) and raised its 2026 growth outlook. The company, which builds rugged high-performance computers for edge computing, is on pace for the stock's third drop of 7% or more this month.

## Higher forecast, softer margins

The company lifted its 2026 revenue growth outlook to about 40%, from a prior range of 25% to 30%, it said in its [third-quarter results](https://www.globenewswire.com/news-release/2026/10/28/3390120/0/en/one-stop-systems-reports-q3-2026-results.html?ref=bullished.co).

On the [earnings call](https://www.benzinga.com/news/26/10/62659654/one-stop-systems-q3-2026-earnings-call-transcript?ref=bullished.co), the CFO said fourth-quarter margins will dip and cash use will stay negative, with a $5.6 million collection slipping out of the quarter. Management said adjusted earnings were held back by $0.5 million of bad debt tied to a former customer's bankruptcy and $0.4 million of legal costs from a settlement.

The CEO described [programs worth $100 million](https://www.benzinga.com/news/26/10/62659654/one-stop-systems-q3-2026-earnings-call-transcript?ref=bullished.co) as transformative for the company, none of which are in 2026 guidance, according to the call.

## A $50 million stock program

The company also set up an [at-the-market program](https://www.sec.gov/Archives/edgar/data/0001394056/000119312526435254/oss-20261028.htm?ref=bullished.co) to sell up to $50 million of stock over time. Proceeds are earmarked for acquisitions, working capital and general corporate purposes.

Selling new shares adds to the share count holders own a piece of.

## A stock already well off its high

One Stop Systems designs and sells rugged computers, high-speed switch fabrics and storage systems for AI, sensor processing and autonomy uses on platforms such as planes, drones, trucks and ships. Its customers span commercial/industrial and military/government markets.

Shares were down about 6% year to date at Tuesday's close, while the S&P 500 was up about 13%. The stock had fallen 27% over the prior month and sat 66% below its highest close of the past year, set on June 2.

The company said it expects several large, multimillion-dollar orders to close during the fourth quarter.
