Summary

  • Cable One expects to pay approximately $480 million on or before 1 October 2026 for the roughly 55% of MBI it does not own. It separately expects MBI to have approximately $920 million of net debt, in term loans maturing in November 2027, when the subsidiary is consolidated.
  • The parent had $166.2 million of cash and $700 million of unused revolver capacity at 30 June, but already carried $3.06 billion of gross debt. Its proposed MBI loan exchange attracted acceptances for only about 34% of the term loans, and Cable One then expected not to complete it.
  • MBI’s data units fell 5.9%, quarterly revenue fell 7.1%, operating expense rose 15.0% and capital expenditure rose 28.4%. Closing transfers control; it does not prove that the acquired network can refinance or earn through its debt.

A closing cheque is not a debt retirement

Cable One already owns about 45% of Mega Broadband Investments Holdings, the company behind the Vyve Broadband brand. On 2 January 2026, the other investors exercised a put that requires Cable One to acquire the remaining roughly 55%, subject to approvals and closing conditions. The transaction is contemplated to close by 1 October 2026 unless Cable One chooses an earlier date.

The June-quarter filing supplies two numbers that should never be collapsed. The first is an expected Put Price of approximately $480 million for the equity that Cable One does not own. The second is approximately $920 million of MBI net indebtedness expected to remain outstanding when MBI becomes a wholly owned subsidiary. Those term loans mature in November 2027.

Adding the figures produces a useful gross burden frame of about $1.4 billion. It does not produce a contractual purchase price or a precise pro forma enterprise value. The equity formula itself uses MBI’s adjusted EBITDA for the year ended June 2025 and its net indebtedness. Closing adjustments, the financing of the cheque and the acquired debt balance can all move. The honest statement is narrower: Cable One faces an equity cash requirement and, separately, responsibility for a larger financed balance inside MBI.

The distinction is more than accounting. The $480 million is expected at closing. The $920 million does not necessarily need to be paid that day, but its November 2027 maturity starts a second clock only 14 months later. A successful wire transfer in October can therefore be followed almost immediately by a refinancing test.

The price already has a history

The 2026 cheque is not the first transfer to MBI’s other owners. Under a December 2024 amendment, Cable One paid them $250 million. They also received the proceeds of $100 million of new debt raised at MBI. The combined $350 million reduces the later Put Price dollar for dollar.

That history prevents two opposite errors. The $350 million should not be added again as if it remained payable at closing. Nor should it disappear from an assessment of how value and leverage moved before full control. The cash payment was funded by Cable One; the debt-funded distribution remained inside MBI’s capital structure. The amendment says the new debt and its interest and fees are excluded from the net-debt input used to calculate the Put Price. Exclusion from a pricing formula is not cancellation of a liability.

The amendment also gave Cable One an incentive to choose timing. An early closing reduces the Put Price at a 12% annual rate from 1 October back to the actual closing date. Yet the Q2 filing still used 1 October for its estimates. Until a final closing statement exists, $480 million and $920 million remain management estimates, not fixed settlement figures.

Liquidity can fund a cheque and still become tighter

At 30 June, Cable One held $166.191 million of cash and cash equivalents. Its $1.25 billion revolving credit facility had $550 million drawn at 5.5%, leaving $700 million available. Management said cash, expected revolver capacity at the transaction date and operating cash flow should be sufficient to fund the Put Price; it also left open the possibility of incremental financing.

That is a credible funding map, not proof of surplus liquidity. Cable One already reported $3.058 billion of gross debt. During the first half it drew $575 million on the revolver to repay notes that matured in March, then repaid $25 million. The unused portion of a facility is borrowing capacity, not cash created without a liability.

Operating performance also determines how much room remains after closing. Cable One generated $239.077 million of operating cash in the first half, down 8.5% year on year. Its second-quarter revenue fell 8.4% to $348.926 million; adjusted EBITDA fell 14.6% to $173.460 million while capital expenditure rose 8.2% to $74.002 million. The acquisition cheque therefore competes with network investment, debt service and the needs of a parent whose own earnings base is contracting.

The relevant question is not whether $166 million plus $700 million is arithmetically greater than $480 million. It is what the consolidated group’s liquidity, leverage and interest burden look like after the funding mix is chosen and MBI’s debt is brought inside the reporting perimeter.

The first refinancing proposal did not clear the field

Cable One tried to create an alternative path for MBI’s term loans in June. It offered lenders combinations of cash and new Cable One first-lien loans. One class would sit “first out”, bear Term SOFR plus 2.25% and mature within six years of the new facility. A second-out class would bear Term SOFR plus 3.00% and mature within seven years of closing.

The collateral shift was material. The proposed loans would have been secured on a first-priority basis by substantially all assets of Cable One and the restricted subsidiaries that guarantee its existing credit facilities. Participating MBI lenders would exchange claims on the acquired company for new claims in the parent’s secured structure; non-participants would remain lenders under the MBI credit agreement.

Only about 34% of outstanding MBI term loans delivered irrevocable acceptances. In its later 10-Q, Cable One said no final determination had been made but that it then expected to exercise its right not to consummate the exchange and would explore other options.

This is not evidence that refinancing is impossible. It is evidence that the announced structure did not attract enough participation to become the chosen solution. The debt remained a separate obligation, its maturity remained November 2027, and the eventual division among repayment, extension, exchange and new financing remained unresolved.

The acquired cash engine is running backwards

Debt can be refinanced when operating cash supports the next creditor. MBI’s current trajectory makes that proof more demanding. At June 2026 it reported 200,384 data primary service units, down 12,452 or 5.9% from a year earlier. Residential data revenue fell 11.0% to $40.623 million. Total quarterly revenue fell 7.1% to $71.988 million.

The mix was not uniformly weak. Business-services revenue rose 3.2% to $19.432 million. But operating expense, excluding depreciation, amortisation and asset-disposal gains, rose 15.0% to $36.446 million, while capital expenditure rose 28.4% to $20.261 million. Falling revenue combined with rising operating and investment demands is exactly the pattern that makes a fixed maturity harder to absorb.

The direction had already changed from the acquisition announcement. In January, Cable One described MBI as having about 210,000 residential and business data customers, 675,000 passings and approximately $310 million of revenue in the 12 months to September 2025. The June customer count was just over 200,000. The figures use slightly different dates and definitions, so they are not a clean quarterly bridge, but they reinforce the year-on-year decline disclosed in the 10-Q.

Cable One also reduced the carrying value of its MBI investment from $386.402 million at year-end to $31.817 million at June and recorded a $349.8 million non-cash impairment based on MBI’s performance and updated forecasts. An impairment does not send cash to lenders and cannot by itself predict the acquisition’s outcome. It does show that the economic expectations attached to the existing 45% stake were revised sharply before Cable One assumed full control.

What control must now produce

Full ownership can change the operating result. Cable One can combine procurement, systems, marketing and network practices across a larger rural footprint. It can remove duplicated costs, standardise offers and allocate capital across both businesses. Those are plausible sources of value, not yet realised cash.

The order of proof matters. First comes closing, with a final Put Price and funding mix. Next comes a consolidated balance sheet that shows the actual MBI debt brought in and any acquisition financing added at the parent. Then comes operating evidence: data-unit retention, residential revenue, business-services growth, expense control and capital intensity. Finally comes a 2027 refinancing or repayment that does not consume the operating gains meant to justify the acquisition.

The optimistic case is not simply that Cable One owns more passings. It is that customer losses slow, business revenue remains resilient, integration lowers cost and the combined company reaches lenders with improving cash generation before November 2027. The weak case is a completed acquisition followed by continued subscriber decline, heavier capital needs and refinancing on terms that transfer more value or collateral priority to creditors.

Cable One’s October cheque will settle an equity right. It will not settle the acquired balance sheet. The investment case begins where the deal announcement ends: with $920 million of debt that must meet a healthier operating network or a willing refinancing market before its own clock expires.
