Why LM Meridian
The technical bench of a global firm, with the discretion and speed of a boutique.
Big-Four trained partners
Audit, IFRS, USGAAP, internal control and transfer pricing experience earned inside global firms — applied to your business directly, not by a rotating team of juniors.
Cross-border MX–USA
USMCA, transfer pricing, BEPS, withholding, entity structuring, intercompany flows and dual-jurisdiction reporting handled end-to-end.
Outcome-driven engagements
Clear scope, fixed fees where it makes sense, and one partner accountable for the result — not an account manager forwarding emails.
Services
Five practices. One partner. Measurable value.
Audit & Assurance
Statutory and special-purpose audits under IFRS and Mexican standards. Integrated internal-control review. Audit-ready financials for banks, investors and acquirers.
Tax & Transfer Pricing
Mexican corporate tax, cross-border structuring, transfer pricing documentation, BEPS alignment, withholding and treaty optimization.
Valuation
Fair-value reports for M&A, capital raises, litigation, ESOPs, PPA and tax purposes. Defensible methodology, USPAP-aligned.
Fractional CFO & Advisory
Senior financial leadership embedded in your company — KPI architecture, cash-flow control, board reporting, fundraising readiness.
M&A & Capital Markets
Sell-side and buy-side advisory, financial due diligence, transaction structuring and post-merger integration for the lower mid-market.
Internal Control & Risk
COSO-aligned control frameworks, segregation of duties, fraud-risk assessments and remediation roadmaps.
