Due Diligence & Acquisition Support
Four decades of hands-on experience spanning fiber engineering and deployment, wireless spectrum valuation, ISP acquisition due diligence, and financial modeling of broadband infrastructure assets. This is not advisory built on research reports. It is built on having been inside these transactions, these networks, and these markets — repeatedly, at senior levels, across every major platform type. When we identify a risk in a proforma or a competitive dynamic that changes a deal's outlook, it is because we have seen that pattern before and know how it resolves.
We examine what the proforma is built on—the assumptions behind penetration rates, ARPU stability, churn projections, and competitive dynamics—and stress-test them against actual market conditions, infrastructure realities, and the regulatory landscape.
We support the full acquisition process—from initial asset evaluation through management interviews, competitive analysis, and integration readiness—at the principal level.
ISP & Broadband Valuation
Valuing an internet service provider requires understanding not just what the business is today, but what it will be under the competitive conditions arriving in its markets over the next three to seven years. Overbuilders, fiber-to-the-home expansions, fixed wireless alternatives, and satellite broadband entrants are reshaping the competitive landscape of markets that were once predictable. Most sellers' proformas do not reflect this.
We build and validate financial models grounded in actual network capability, real subscriber data, and defensible market analysis. We model ARPU trajectory under competitive pressure, churn sensitivity across customer segments, capital expenditure requirements for technology currency, and the revenue scenarios that determine whether projected returns are achievable.
We advise both buyers and sellers—ensuring buyers understand what they’re acquiring, and sellers present their assets with clarity that withstands diligence.
Wireless Spectrum Advisory
Spectrum is simultaneously one of the most valuable and least understood assets in telecommunications. Its value is contingent — on regulatory outcomes, on technical feasibility, on carrier deployment timelines, and on the competitive dynamics of adjacent bands. We have spent decades developing the kind of granular, real-world expertise that turns spectrum questions from binary guesses into structured analysis.
Our spectrum practice covers the full landscape: public and private equity and debt valuation of spectrum portfolios, evaluation scenarios for all major North American carriers, FCC and NTIA regulatory projection and ruling impact analysis, re-farming binary impact assessment for esoteric band decisions, capacity analysis, and the real competitive consequences of spectrum deployment decisions.
We have led and supported Fixed Wireless Access deployments and can assess FWA strategy, feasibility, and financial modeling with depth that few advisors bring to this space.
Fiber: Engineering, Deployment & Modeling
Fiber financial models fail when they are built by people who have never managed a build. Construction timelines slip. Permitting costs exceed estimates. Activation rates underperform projections because competitive response was modeled too generously. We know this because we have lived it — planning, engineering, deploying, and operating fiber networks across a range of market types and build conditions.
We bring operational expertise into the financial modeling process, ensuring that proformas reflect realistic build costs, achievable construction timelines, credible take-rate ramp curves, and appropriate competitive defensibility assumptions. For investors evaluating fiber assets, we identify where the numbers are grounded in reality and where they require adjustment.
For operators planning builds or capital raises, we develop financial models and investor narratives that can withstand sophisticated scrutiny — because we built them to the same standard we apply when we're on the buyer's side of the table.
Technology Migration & Competitive Impact
The single most underpriced risk in telecom investment today is the pace at which generational technology transitions are changing the competitive landscape of markets that investors thought were stable. The arrival of new access technologies — whether overbuilt fiber, upgraded hybrid networks, or fixed wireless alternatives — does not simply add competition. It restructures pricing, erodes ARPU, and accelerates churn in ways that compound over the typical PE hold period.
We model the financial impact of technology migration on specific markets and specific assets. We analyze the timeline of competitive arrival, the likely pricing response, the customer segment vulnerability by service tier, and the resulting effect on revenue, ARPU, and churn over a five-to-seven year horizon. We then map this directly to the proforma assumptions under review, quantifying where the gap between projection and likely reality is most significant.
This is often where we add the most value—where deals that look attractive on a trailing-twelve-month basis reveal forward-looking risks that fundamentally alter the return profile.
Public & Private Equity Research — Expert Network Engagements
Institutional investors — across public equity, public debt, private equity, and credit — engage us through expert networks including GLG, Gerson Lehrman, AlphaSights, and Thirdbridge when they need to understand how spectrum decisions, broadband policy changes, regulatory rulings, or competitive technology shifts will affect the companies they hold or are evaluating.
These are not generalist briefings. We provide precise, experience-grounded analysis of specific regulatory scenarios and their real-world competitive and financial consequences: what an FCC ruling on a specific band actually means for a carrier's network economics, whether a satellite broadband entrant poses genuine risk to a fixed-line asset, what a fiber overbuilder's timeline means for a cable company's ARPU outlook in a specific market type.
We work with both public-side investors evaluating large-cap carriers and debt instruments, and private-side investors working through the logic of specific acquisition opportunities or portfolio company performance questions.

Private Equity & Infrastructure Investors
This is the core of our practice, and it is where our depth creates the most decisive advantage for clients.
Private equity firms investing in ISPs, fiber networks, fixed wireless platforms, or other telecom infrastructure assets face a consistent challenge: the information they receive from sellers is structured to support a transaction. Management presentations and proformas are built to show assets at their best. The questions that matter most — how defensible is this subscriber base against the competitors arriving in the next 18 months? What does ARPU actually look like under realistic competitive pressure? Are the capital expenditure assumptions sufficient to maintain network competitiveness? — are rarely answered clearly in a data room.
We answer those questions. We go into the infrastructure, the subscriber data, the market competitive dynamics, and the financial model with 40 years of pattern recognition and more than 1,000 completed engagements as our reference point. We know what telecom assets look like when they perform, and we know what the early indicators of underperformance look like before they show up in financials.
We work alongside PE deal teams from initial asset evaluation through final close, providing the sector-specific depth that internal generalist teams cannot replicate and that determines whether a transaction creates or destroys value.
- Full infrastructure and subscriber base due diligence — network quality, coverage gaps, technology currency, and upgrade requirements
- Proforma validation and stress testing across competitive scenarios — what the numbers look like if competition arrives on the timeline we assess as realistic
- ARPU and churn trajectory modeling under generational technology and competitive entry pressure
- Blind spot identification — the specific risks the seller's presentation is structured to minimize or omit
- Management interview preparation — the technical and operational questions that reveal whether management understands the competitive dynamics ahead
- Forward-looking competitive displacement analysis — who is building in these markets, on what timeline, and with what likely pricing impact
- Senior acquisition support through close and integration readiness assessment
Operators Preparing for Sale or Capital Raise
ISPs, regional fiber operators, fixed wireless providers, and other telecom infrastructure businesses approaching a sale process or capital raise face an asymmetric challenge: the buyers and investors they want to attract will have advisors — like us — stress-testing every claim they make. The operators who transact on the best terms are the ones whose proformas and narratives hold up under that scrutiny, because they were built to the same standard the buyer applies.
We work with operators to develop financial models and investor narratives that are grounded in defensible data and structured to survive sophisticated diligence. This is not about presenting a business optimistically — it is about presenting it credibly. Sophisticated PE buyers discount numbers they don't believe. A proforma built on assumptions that hold up to questioning commands a better multiple than one that doesn't.
We also help operators understand their own competitive position honestly — including the risks that buyers will identify — so they can address those risks proactively rather than having them surface in a process in a way that damages valuation or disrupts a transaction.
- Sell-side proforma development built to withstand PE-quality due diligence scrutiny
- Competitive defensibility analysis — an honest assessment of the risks sophisticated buyers will identify and how to address them
- Asset positioning and investment narrative development — grounded in data, structured for the buyers most likely to transact
- Capital raise preparation — financial model development, investor presentation support, and process preparation
- Strategic guidance on timing, structure, and buyer or investor targeting — leveraging direct relationships across the PE and infrastructure investment community
- Pre-process infrastructure and operational assessment — identifying and addressing issues before they surface in a buyer's diligence
