What if your company doesn't have a prepackaged SWOT? You can use your own noggin and create one yourself (get used to doing this).
The companies themselves will address these concerns in their annual report. This is usually done in their 10-K section 1A (Risk Factors). There is no uniform presentation; the company will list potential adverse scenarios to its profitability (threats and weaknesses), as well as its market strategy and assumptions (strengths and opportunities). They will continue to address these points throughout the rest of the 10-K.
