AI synthesis · written from this company's SEC filings · not investment advice

What the filing actually says.

AI · forensic preset

This synthesis rests only on the eight-year revenue, net income, and operating income figures in the data set. No Beneish M-Score, Piotroski F-Score, Altman Z-Score, or Fog Index is on file, so this write-up gives no forensic reading in either direction, and the absence of a score is not a clean result. The Beneish M-Score is a screening model that estimates the likelihood of earnings manipulation from several ratios involving receivables, margins, and accruals; a flagged result calls for a closer read, not a conclusion. Those tests would need the full balance sheet and cash flow statement, which were not provided. What the income figures do show is a mixed picture. Operating income of $1.16 billion in 2025 is the highest of the years shown, yet net income of $152.25 million is the lowest of the eight years shown, and net income has fallen in each year since its 2022 peak of $562.15 million. Revenue also moves sharply between years, from $4.23 billion in 2018 to $1.58 billion in 2019, and from $1.62 billion in 2021 to $5.1 billion in 2022. Swings of this size may reflect changes in reporting scope or presentation, but the data does not say why. Readers may want to confirm the comparability of each year in the filings before drawing trend conclusions.

Catalyst.The data provided for this synthesis does not include MD&A text, so management's own explanation of what is driving the business is not available here. The reported numbers show one visible trend: revenues rose from $6.15 billion in 2024 to $6.9 billion in 2025, an increase of about 12%, and operating income rose from $1.01 billion to $1.16 billion, about 15%. Readers may want to look at the MD&A in the company's 2025 annual report to see which operations or factors account for that growth.

Hidden risk.The most important tension in the numbers is the gap between operating income and net income. Operating income rose about 15% in 2025, yet net income fell from $183.67 million to $152.25 million, a decline of about 17%. Net income was roughly 13% of operating income in 2025, compared with about 18% in 2024. The data provided does not explain the cause, which could lie in items reported below operating income. A careful reader would need the full income statement and the risk-factor section to see what widened the gap.

What traders are betting.

The scores above come from what IRM reports to the SEC. These readings come from how traders are positioned in its shares. They change quickly, they can be wrong, and they are not part of the verdict.

The metric

Shares that traders have borrowed and sold, betting the price will fall, and not yet bought back. Brokers report the total to FINRA twice a month. Days to cover divides it by the shares that change hands on a typical day.

What it tells us

Few traders are betting against IRM. Levels this low are common for large, widely held companies.

Little changed since the Aug 31 report (+8.3%).

At normal trading volume, short sellers would need about 4.1 days to buy back every borrowed share.

How investors use it

  • Squeeze watching. Some aggressive traders seek out heavily shorted stocks, betting that good news will force short sellers to buy back shares and push the price higher.
  • Hedging. Funds short one company to offset risk in another, often owning a stronger business and shorting a weaker one in the same industry.
  • Timing. Chart-based traders pair rising short interest with price patterns, such as a break below a level where buyers used to step in, to decide when to enter or exit.
  • Warning sign. Some owners treat a sharp rise in short interest as a red flag and respond by tightening stop-loss orders or holding smaller positions.
