INWIT cuts guidance as tower-contract disputes move into court

Italian tower company INWIT has cut its financial outlook due to a dispute with its largest customers, Telecom Italia (TIM) and Fastweb–Vodafone. The conflict stems from TIM and Fastweb's plan to jointly build new telecom towers outside of INWIT’s infrastructure, renegotiate long-term agreements, and potentially reduce their dependence on INWIT for tower services.

• On 19 March 2026, INWIT reduced revenue guidance to €1.050–1.090 billion and recurring free cash flow guidance to €550–590 million.
• On 11 July, a Milan judge denied urgent relief against TIM. The interim order did not decide the contract’s duration; a merits case is still to follow.

The cut can be measured

The clean comparison comes from INWIT’s own releases. In September 2025, its 2026 outlook pointed to the lower end of a €1.135–1.165 billion revenue range and the lower end of €655–675 million of recurring free cash flow. The 19 March 2026 update replaced those figures with €1.050–1.090 billion and €550–590 million. Expected EBITDA margin moved from above 91% to about 90%, EBITDA after lease costs (EBITDAaL) from about 75% to about 72%, and financial leverage from 5.2 times to 5.5 times.

INWIT reiterated the revised ranges in its 12 May first-quarter results. Q1 revenue was €264.1 million, EBITDAaL €189.9 million, EBITDAaL margin 71.9%, net profit €81.0 million and recurring free cash flow €176.2 million. The 11.5% year-on-year rise in quarterly RFCF does not reverse the full-year cut: tax, working-capital, interest and payment timing can move cash between quarters.

Cash-flow and accounting boundaries

INWIT defines RFCF as an alternative performance measure built from operating cash flows after tax, working-capital changes, recurring capital expenditure and net financial outflows. It is not interchangeable with statutory operating cash flow, net income or an undefined “cash flow” number. EBITDAaL likewise means EBITDA after lease costs. A guidance revision is not by itself an impairment, litigation provision or revenue-recognition decision. The public material reviewed does not establish such a final accounting conclusion for these disputes.

Two MSAs, opposing contractual positions

The Master Service Agreements cover tower hosting, reserved space and associated services over long terms; calling them simple property leases understates the operating package. INWIT says options exercised in August 2022 extended the contracts to August 2038. Fastweb–Vodafone says instead that a change-of-control right preserved from the 2020 transaction permits its MSA to end in March 2028 after two years’ notice. INWIT rejects that interpretation and ties the agreement to its roughly €5.7 billion purchase of Vodafone Italia’s towers.

TIM notified INWIT on 29 March of an August 2030 end date, or 31 March 2028 if its alternative change-of-control condition is upheld. INWIT says the TIM MSA remains effective to 2038. These are party positions, not decided facts. INWIT also said it offered arbitration and TIM declined; that statement does not show an arbitration is under way.

The 6,000-site venture is still conditional

On 19 March, TIM and Fastweb announced a non-binding plan for an initially 50/50 joint venture to develop up to 6,000 new passive sites in phases. Swisscom’s announcement says it would be open access, funded with third-party equity and debt, and subject to definitive agreements and customary approvals; the anchor tenants would sign long-term service agreements. It is neither an operating network nor an immediate wholesale migration from INWIT. Swisscom’s statement that the equity-accounted venture would not affect its own free cash flow or guidance cannot be transferred to INWIT’s accounts.

What the courts have and have not decided

Fastweb filed a civil merits action over its notice, and INWIT sought interim relief. No final public merits decision in that case was identified as of 14 July. In the TIM matter, Reuters reported on 13 July that the urgent request had been rejected. INWIT’s account of the 11 July order says the judge found no present urgency but did not interpret the disputed clauses or determine the MSA’s duration. INWIT plans to start the merits case and is considering a challenge to the order. TIM describes the same order as supporting the legitimacy of its exit. Both descriptions require attribution.

The watchpoints

The near-term risk is a combination of price renegotiation, phased site migration, legal cost and slower densification, not proof that all contract revenue disappears at once. Investors should track merits proceedings and any appeal, assisted negotiation, TIM and Fastweb migration schedules, definitive joint-venture documents, approvals and financing, then INWIT’s half-year results. Revenue, EBITDAaL, RFCF, capex, dividend and leverage should be checked against the 19 March ranges while keeping company claims, customer positions, interim orders and final judgments in separate columns.
