Buy-side commercial due diligence

Real case: Cisco’s acquisition of Splunk

Cisco announced its agreement to acquire Splunk on 21 September 2023 for $157 per share in cash, representing approximately $28 billion in equity value, and completed the transaction in March 2024.

Typical buyer: Corporate development team, strategic acquirer, private-equity fund Mode: Historical decision reconstruction plus ex-post validation

Prepare a retrospective buy-side commercial due diligence report for Cisco’s proposed acquisition of Splunk, using 20 September 2023 as the decision cutoff. Using only information available by that date, assess the addressable markets for cybersecurity, security analytics, observability, and machine-data platforms; Splunk’s competitive position, cloud transition, recurring-revenue quality, customer concentration, retention proxies, pricing power, sales efficiency, competitive threats, and plausible revenue and cost synergies with Cisco; then determine whether the proposed $157-per-share price and approximately $28 billion equity valuation were commercially justified under base, upside, and downside scenarios.

Add a completely separate ex-post validation covering 21 September 2023 through 27 July 2026. Test the original investment thesis against Cisco’s subsequent disclosures, product integration, customer and partner developments, financial performance, competitive changes, restructuring or integration costs, and any evidence that projected synergies did or did not materialize; do not allow this later evidence to influence the original pre-deal recommendation.

Primary benchmark pressure: Market reconstruction, SaaS economics, valuation, synergy credibility, and resistance to hindsight bias.
