Recommendation

StockSavvy.ai recommends a 'hold' rating. While the company is raising its full-year guidance and implementing a strategic plan to drive future growth, the reported year-over-year revenue decline due to reimbursement challenges presents a near-term headwind. The successful execution of the 'Project Horizon' plan and stabilization of revenue will be critical for future upside. Investors should monitor the impact of the strategic initiatives and the evolving reimbursement landscape.
