Shares of India's largest airline, IndiGo, climbed on Friday as investors responded positively to its efforts to protect profitability through higher airfares, disciplined capacity expansion and network optimisation, despite the continued pressure of elevated aviation fuel costs on its earnings.

The airline's shares rose approximately three per cent to 4,810 rupees as of 9:37 a.m. Indian Standard Time, reaching their highest level in two weeks. The gain outperformed the broader market, with the benchmark Nifty 50 index advancing 0.22 per cent.

The positive market reaction came after IndiGo reported its third consecutive quarterly loss, although the latest deficit narrowed compared with the corresponding period last year. Revenue growth and improved ticket pricing helped cushion the impact of rising operating expenses, particularly aviation fuel.

Fuel expenses, which accounted for nearly 38 per cent of the airline's total costs, increased sharply amid higher global oil prices, continuing to weigh on its financial performance.

Despite the earnings pressure, analysts believe IndiGo's ability to maintain relatively strong fares, manage operating costs and optimise its flight network could help preserve its longer-term profitability prospects.

Brokerage firm Jefferies described the airline's quarterly performance as largely in line with expectations, highlighting the resilience of ticket prices and management's guidance for low single-digit capacity growth in the current quarter.

The brokerage noted that a controlled approach to capacity expansion could help the airline maintain pricing discipline and avoid excessive competition in a market where available industry capacity remains relatively tight.

Ambit Capital, however, said the earnings upgrade cycle had yet to gain momentum, although it identified favourable supply-and-demand conditions as a potential source of support for the airline.

The brokerage also highlighted IndiGo's fleet and network optimisation strategy, including the gradual reduction of its reliance on expensive damp-leased wide-body aircraft.

Damp leasing involves an arrangement in which an airline leases an aircraft along with maintenance and insurance support, while providing its own flight crew.

Similarly, Emkay Global identified aviation fuel expenses as the key factor investors should monitor, but said higher fares, premiumisation initiatives and adjustments to the airline's network could help support earnings.

These measures are expected to improve revenue generation and operational efficiency as the industry continues to operate under capacity constraints.

Analysts Maintain Positive Outlook

Market analysts remain broadly positive about IndiGo's investment prospects despite the recent earnings challenges.

Data compiled by LSEG showed that the average recommendation from 25 analysts covering the airline remained at "buy", with a median price target of 5,700 rupees.

The target suggests that analysts see further potential for the airline's shares, supported by its market position, pricing power and efforts to manage operating costs.

However, IndiGo's stock has declined five per cent so far this year, compared with a 12 per cent fall in the benchmark Nifty 50 index.

The airline's immediate performance outlook will depend largely on how effectively it manages fuel-related cost pressures while sustaining ticket prices and controlling capacity growth.

For investors, the balance between higher operating expenses and the airline's pricing and cost-management initiatives remains central to assessing its earnings recovery.
