Valuation and Financial Advisory

Independent valuation and financial decision support in complex transaction and investment contexts


Siller Advisory provides independent valuation and financial advisory services to owners, executives, investors, and institutions facing complex financial decisions. Our work supports transactions, investments, restructurings, and strategic capital decisions where valuation accuracy, market realism, and defensible assumptions are critical.


We operate as an independent advisor, delivering objective analysis and clear judgment in situations where financial outcomes are material and long‑term.


What We Do

Our valuation and financial advisory services focus on decision‑critical situations, including:


  • Company and project valuation
  • M&A and transaction‑related advisory support
  • Investment appraisal and capital allocation analysis
  • Strategic and financial restructuring scenarios
  • Independent reference, validation, and review opinions


Our role is to ensure that financial decisions are grounded in robust analysis, transparent assumptions, and market‑consistent logic.

Valuation Grounded in Market Reality

A defining element of our valuation work is the direct integration of market benchmarks, price forecasts, and macro‑economic scenarios into financial analysis.


We incorporate:


  • Long‑term energy and raw‑material price assumptions
  • Policy, regulatory, and transition‑related impacts
  • Market cycles, volatility, and structural change
  • Cross‑commodity and cross‑sector dependencies


This approach reduces reliance on static assumptions and ensures that valuation outcomes remain robust and defensible across scenarios.

M&A and Transaction Advisory Support

Within Valuation & Financial Advisory, we support M&A and transaction processes through independent, analytical decision support, including:


  • Target valuation and transaction scenario analysis
  • Validation of pricing, synergies, and cost structures
  • Sensitivity and downside case assessment
  • Benchmark‑anchored support for negotiations


We do not act as a broker. Our role is to strengthen governance and decision quality through independent analysis.

Analytics Driven Financial Analysis

Our valuation and financial advisory work is supported by advanced analytics and decision‑science frameworks that allow us to assess uncertainty, stress‑test assumptions, and evaluate outcomes across a wide range of scenarios.

We apply structured quantitative methods to:


  • Test valuation assumptions under different market conditions
  • Assess downside risk, volatility, and sensitivity
  • Validate business plans and financial projections
  • Translate complex analytical output into board‑ready insight


These analytics capabilities ensure that valuation conclusions are robust, defensible, and decision‑relevant.

Price Forecasts and Market Benchmarks

Credible valuation depends on realistic forward‑looking assumptions. We therefore integrate long‑term price forecasts and independent market benchmarks directly into valuation and transaction analysis.

Our price‑forecasting and benchmarking work supports:


  • Long‑term energy and raw‑material cost assumptions
  • Investment, financing, and capital‑allocation decisions
  • Policy, regulatory, and transition‑related scenario analysis
  • Market volatility, cycles, and structural change assessment


By grounding valuation inputs in independent, market‑anchored forecasts, we improve the durability and credibility of valuation outcomes.

Price Forecasts

Outcome

Valuation & Financial Advisory engagements are designed to deliver:


  • Independent, objective valuation conclusions
  • Market‑anchored financial assumptions
  • Clear understanding of value drivers and risks
  • Decision‑ready analysis for boards, investors, and stakeholders


Our focus is clarity, independence, and decision relevance.
