A CPA firm is auditing Innovatech, a pre-IPO software-as-a-service (SaaS) startup. The audit team notes the following: 1. Innovatech recognizes revenue from 3-year, non-cancellable contracts at the point of sale, arguing the cash is received upfront and the service is 'always-on'. 2. The company recently pivoted its business model, causing significant recurring losses. Management's going concern assessment relies heavily on securing a future Series C funding round, for which they only have a verbal expression of interest from a venture capital firm. 3. The lead developer, who wrote most of the proprietary source code, left the company acrimoniously and has threatened litigation over intellectual property rights. Which of the following audit opinions is most appropriate given these circumstances, assuming all issues are material?
