"no historical financial statements of Genco or pro forma financial information are required to be filed under Item 9.01(a) and (b)"

Pro forma financial information are adjusted financial numbers that show how a company’s results might look after a specific event or after removing one-time items, like a cleaned-up or “what if” version of its earnings. Investors use these figures to compare performance, judge future profitability, or evaluate the impact of mergers, restructurings or large transactions, but they require scrutiny because adjustments can make results look rosier than standard accounting statements.
