5. Risk Factors (Item 1A)

Key Risks

1. Ongoing losses—needs continued capital raises and may never be profitable.
2. Customer concentration—top two customers >30% of A/R; potential revenue swings.
3. Dependence on partners—Medline, WellSpring, MicroSafe; partnership terms and performance are critical.
4. Regulatory environment—EU MDR, FDA reclassification of HOCl devices; potential new pre-market requirements.
5. Manufacturing & supply chain—single Mexico facility; Mexico tax & intercompany loan complications (thin capitalization rules; $10.9 M principal + $26.4 M interest at risk).
6. Currency & geopolitical—U.S./Mexico trade policies; foreign exchange impacts (24% A/R concentration in Mexico pesos).
7. Competition—existing wound/dermatology products (antibiotics, steroids, growth factors); potential HOCl copycats.
8. Intellectual property—patent scope & defense; HOCl know-how is partly unpatented.

Mitigants include diversified product lines, multi-jurisdictional clearances, robust R&D pipeline, and strategic licensing.

6. Outlook & Investment Score (1–10)

Growth Drivers

• Expanded distribution via Medline (U.S./Canada) & WellSpring
• EU MDR & UK MHRA approvals
• New FDA 510(k) clearances (OTC eye, enhanced biocompatibility)
• Pipeline projects: intraoperative pulse lavage, expanded NPWT, nasal/OR device claims, cell therapy adjuncts
• Projected steady cash burn < $1 M QOQ

Challenges

• Continued need for capital & potential equity dilution
• Mexico withholding taxes & loan repayment hurdles
• Risk of FDA reclassification & new MDR requirements
• Intense competition from incumbents + new entrants

Investment Score: 6.5/10

• Positives: Unique HOCl platform; multi-channel reach; clear regulatory roadmap; improving financial metrics; strong partner network.
• Negatives: Continued operating losses; capital dependency; regulatory & foreign tax complexities; concentration risk.

Bottom Line: Sonoma is a small‐cap, innovation‐focused HOCl‐tech play. Its clearances and partnerships provide revenue momentum, but profitability hinges on additional capital raises, manufacturing scale, and continued adoption by healthcare professionals.
