Redwood Mortgage Investors IX Changes Auditor to Baker Tilly

What Happened

• Redwood Mortgage Investors IX, LLC announced on April 22, 2026 that it dismissed BDO USA, P.C. as its independent registered public accounting firm and engaged Baker Tilly US, LLP as its new independent registered public accounting firm. The change was approved by the Company’s manager, Redwood Mortgage Corp.
• BDO’s audit reports for the fiscal years ended December 31, 2025 and 2024 contained no adverse opinions or disclaimers and were not qualified or modified. The Company provided BDO with the disclosures in this 8-K and received a letter from BDO dated April 24, 2026 (filed as Exhibit 16.1).

Key Details

• Date of auditor change: April 22, 2026.
• Prior auditor: BDO USA, P.C.; New auditor: Baker Tilly US, LLP.
• BDO reported no disagreements or reportable events for 2025, 2024, or the interim period through April 22, 2026, except that the Company had identified a material weakness in internal control over financial reporting related to evaluation of expected credit losses and fair‑value determination of certain real property collateral — which the Company disclosed it remediated as of December 31, 2025 in its 2025 Form 10-K.
• Neither the Company nor anyone on its behalf consulted Baker Tilly on accounting or auditing matters for 2024, 2025, or the interim period through April 22, 2026.

Why It Matters

• A change in independent auditor is material for investors because it affects who will audit future financial statements and may involve a transition period. In this case, the prior auditor issued unmodified reports for the last two years and the Company reports the related material weakness was remediated as of December 31, 2025, which reduces near‑term red flags.
• Investors should note the auditor change and monitor upcoming filings and audited financial statements from Baker Tilly for any differences in reporting, disclosures, or audit scope.
