If the parent company is publicly traded, you may find great info in SEC filings
--esp. the 10-K report.
When a company is owned by another company, the company traded on the exchange that owns other companies is called the parent company; the companies under the parent are called subsidiaries.
If your company is a subsidiary, you will need to research the parent company. You might not be able to find separate financial info on the subsidiary. However, many details on the subsidiary might be found in the parent company's SEC filings (esp. the 10-K report), articles, and other sources.
