ICF International, Inc. Q2 FY2026 earnings call

• Overall Financial Performance

  • Adjusted EBITDA margin expanded 10 bps YoY to 11.2% in Q2 2026; non-GAAP diluted EPS increased 12% YoY to $1.86, driven by improved margins, lower taxes, lower interest expense, and reduced share count.
  • Trailing 12-month book-to-bill ratio was 1.09; post-Q2 contract awards exceeded $200 million; end-Q2 total pipeline was $9.3 billion, up 9% sequentially from Q1 2026. 60% of the pipeline ($5.5 billion) is in three core long-term growth markets: commercial energy, technology modernization, and state/local disaster management.
  • Operating cash flow was $99.7 million in Q2; core operating cash flow (excluding restricted cash for utility customer incentives) was $56.7 million, up from $50.4 million YoY; DSO improved to 72 days from 80 days YoY driven by better collections and more advance payments.
  • ICF repurchased 435,000 shares in H1 2026, a first-half company record; end-Q2 net debt was $403 million, down from $457 million YoY, with an adjusted leverage ratio of 2.06.

• Strategic and Operational Updates

  • The diversified, integrated business model provides resilience and competitive advantage: cross-segment, cross-domain capabilities allow ICF to serve all stakeholders in complex markets (e.g., grid reliability, data center development, California energy market monitoring) and deliver broader perspective than specialized competitors.
  • ICF is re-purposing AI-enabled analytics originally developed for federal clients to serve commercial and state/local clients, and expanding state/local offerings to include health expertise and advanced technology solutions.
  • Cost efficiency initiatives: ERP system modernization (contract and vendor management systems) remains on track; AI tools are being rolled out across internal processes to drive back-office efficiency. The company maintains a disciplined approach to indirect spending while prioritizing investment in high-growth areas.
  • M&A strategy remains focused on disciplined tuck-in acquisitions primarily in the commercial energy space, targeting deals that deliver revenue synergies and are accretive shortly after close.

Total Q2 2026 revenue was $474.5 million, flat year-over-year (vs $476.2 million in Q2 2025), up 8.5% sequentially from Q1 2026.

• Commercial Clients: Revenue grew 6% year-over-year, up 13.6% sequentially. Commercial energy sub-segment performance: utility programs (energy efficiency, flexible load management, etc.) grew 6.7% YoY, accounting for 82% of Q2 commercial energy revenue; commercial energy advisory grew 2.5% YoY (8.6% for H1 2026), accounting for 13% of H1 commercial energy revenue; remaining <5% of commercial energy revenue from environmental and planning work is down YoY due to wind project wind-downs in 2025 Q3. Commercial clients represent ~39% of total Q2 revenue.
• State and Local Government Clients: Revenue was down 1.9% YoY, up 9.1% sequentially. Disaster management and recovery services account for 45% of this segment's revenue. This segment represents ~13% of total Q2 revenue.
• International Government Clients: Revenue increased 35% YoY, up 24.2% sequentially, driven by ramp-up of large 2025-2026 contract wins with EU and UK clients. This segment represents ~9% of total Q2 revenue.
• U.S. Federal Government Clients: Revenue declined 9.5% YoY, increased 1.4% sequentially (following 8.6% sequential growth in Q1 2026). Technology modernization accounts for 50% of the segment's $185 million Q2 revenue, growing 4% sequentially. Over 80% of ICF's federal technology modernization work is under outcome-based fixed-price contracts. This segment represents 39% of total Q2 revenue.

Non-federal clients (commercial + state and local + international) account for 61% of total Q2 2026 revenue, up from 57% of total revenue in 2025.

• Full-year 2026 guidance is reaffirmed: total revenue expected between $1.89 billion and $1.96 billion; over 90% of required full-year revenue is already in backlog. GAAP EPS is expected between $5.95 and $6.25, non-GAAP EPS between $6.95 and $7.25.
• Full-year 2026 guidance updates from prior ranges: full-year interest expense lowered to $26 million - $28 million (from $27 million - $29 million); capital expenditures lowered to $23 million - $25 million (from $24 million - $26 million); weighted average share count lowered to 18.2 million shares (from 18.3 million) to reflect H1 share repurchases.
• Full-year 2026 unchanged guidance: target 10-20 bps adjusted EBITDA margin expansion; full-year tax rate ~20.5%; depreciation and amortization between $22 million - $24 million; full-year core operating cash flow (excluding restricted cash impact) between $135 million - $150 million; year-end adjusted leverage ratio expected to be under 1.6 absent acquisitions.
• Quarterly cadence: sequential revenue growth is expected in both Q3 and Q4 2026, with faster acceleration in Q4; year-over-year revenue growth is expected to resume starting in Q3 2026, with federal revenue returning to YoY growth in Q4 2026.
• 2027 outlook: ICF expects a return to mid-to-high single-digit total revenue growth in 2027; non-federal segments are expected to deliver high-single-digit to low-double-digit growth, while federal is expected to deliver low-to-mid single-digit growth.

• Federal government procurement activity remains constrained, with longer sales cycles, frequent bid protests for large contracts, and variability in award timing across different agencies, which has slowed backlog growth in the segment.
• Near-term disaster management revenue is constrained by fewer large-scale federally-declared disasters and funding delays, limiting new near-term opportunities in this core state/local sub-segment.
• Commercial energy advisory revenue can vary quarter-to-quarter due to the timing of client M&A transaction activity and project assignments.
• Energy and environmental planning revenue in commercial energy is temporarily suppressed following the wind-down of large wind energy projects in 2025.

Q: The analyst asks if commercial energy needs mid-teens growth in H2 2026 to hit full-year double-digit growth targets, and what drivers will support this growth. / A: Management confirms the math is correct, and notes strong Q2 contract awards, near-term pending contract negotiations, and a robust commercial energy pipeline support confidence in hitting the target. Additionally, performance fees are typically back-half loaded, and delayed energy advisory work tied to the July 4 IRA tax credit sunset is now resuming, with an expected pickup in H2 M&A activity that will drive advisory revenue. Management adds that core market growth trends remain consistent with the mid-teens growth the segment has delivered over the past two years.

Q: What caused the slight sequential decline in backlog this quarter, and what is the outlook for book-to-bill in Q3? / A: Q2 book-to-bill was 0.85, with the entire decline driven by slower federal procurement activity. Management notes that procurement activity has started to pick up post-quarter-end, and expects a healthier book-to-bill and growing backlog in Q3.

Q: What underlying trends are driving strong international government growth, and how sustainable is this growth? / A: Strong growth comes from ramp-up of large contracts won over the past 18 months, which were delayed by European elections and are now hitting full stride. ICF holds strong positioning on many of these contracts (often as single awardee or top provider on framework contracts with right of first refusal), and the current international pipeline is the largest in company history. ICF is using existing contracts as a launchpad to win new work with additional EU agencies, and expects continued double-digit growth in H2 2026 and into 2027.

Q: Have you seen a market trend of the federal government procuring OEM software licenses directly instead of through integrators, and how is this impacting your technology modernization business? / A: Management says they have not seen any material shift in this practice. Most of ICF's technology modernization revenue is labor-based services, not pass-through license costs. ICF partners across all major OEM and open-source platforms, and has not experienced any fundamental change to market dynamics or partner relationships to date.

Q: What is the outlook for inorganic growth in H2 2026 and 2027, after recent business stabilization? / A: Management remains disciplined and actively searching for strategic, culturally aligned acquisitions that meet financial criteria, with a primary focus on tuck-in deals in commercial energy. ICF has ample balance sheet capacity to pursue deals while maintaining its balanced capital allocation approach of organic investment, dividends, and opportunistic share repurchases.
