Rating case: a tower company plans a debt-funded acquisition that takes leverage past the agency's downgrade trigger. What rating action follows, and what could the company do to avoid it?

Leverage rises from 3.69x to 4.20x, past the 4.0x trigger, so expect the agency to place the rating on review for downgrade at announcement and cut it by a notch on completion unless Zenthra acts. Rs 300 crore less debt brings it to 4.0x: new equity of that amount, about Rs 600 crore of hybrid capital, or a credible commitment to be back under 4.0x within about a year.

Think of a household whose loans are 3.7 times its yearly income, buying a rental flat entirely on a loan that is 7.5 times the flat's rent. The rent is new income, but the new loan is far bigger relative to it, so the household's overall ratio rises. A debt-funded acquisition raises leverage whenever its price multiple is above the buyer's own leverage. Zenthra pays 7.5x for EBITDA of Rs 200 crore, so debt rises by Rs 1,500 crore while EBITDA rises by Rs 200 crore: Rs 6,300 crore over Rs 1,500 crore is 4.20x.

Agencies read the post-deal ratio, not the strategic story, and they act on announcement rather than waiting. The likely sequence is a review for downgrade when the deal is announced, then a one-notch downgrade on completion unless the company shows how leverage will return under the trigger within a stated period, commonly a year or two. Tower cash flows help: long contracts with operators make the EBITDA durable, which is why the agency tolerates 4.0x at all. They also cut the other way: there is little cyclical upside to grow out of the problem quickly, so a promise to deleverage needs to be concrete.

Work out the debt capacity: 4.0x on Rs 1,500 crore of EBITDA is Rs 6,000 crore, so Rs 300 crore of the purchase must come from somewhere other than straight debt. New equity of Rs 300 crore closes the gap exactly. Hybrid capitalDeeply subordinated, very long-dated debt that an agency may treat as partly equity, for example half debt and half equity, when computing leverage. with 50% equity credit needs twice that, about Rs 600 crore, because only half of it counts as equity. Selling towers is slower than it looks: at 10x EBITDA, each Rs 100 crore sold also removes Rs 10 crore of EBITDA, so it takes about Rs 500 crore of sales to get back to 4.0x. The fourth route is time: Rs 350 crore of paydown and 5% EBITDA growth would bring leverage to about 3.78x within a year and 3.39x in two.

The view to present: the deal is sensible for a tower company, but funded all with debt it costs a notch. Fund about Rs 300 crore with equity, or pair the deal with a public, dated deleveraging plan and a dividend pause, and the agency has grounds to hold the rating with a negative outlook instead. Treatment of hybrids and tolerance periods differ by agency, so confirm the current methodology before promising either to the board.
