Monitor for SEC effectiveness of the S-4 and shareholder vote timing. The $100M PIPE and 77%-90% backlog coverage of 2026F guidance provide some downside protection, but the company's history of operating losses and potential SPKL redemptions (up to ~$11M) introduce execution risk. Watch for any changes to deal terms or regulatory delays.
