IndiGo shares gain over 2% on constructive outlook; is growth potential ahead amid cost headwinds?

India’s largest airline operator, InterGlobe Aviation or IndiGo, shares surged more than 2% during the trading session on Monday, September 21, as investors focused on a constructive outlook from a global investment firm and the longer-term growth potential of the company.

Investors' sentiment was further aided by the 2.5% pullback in global crude oil prices, with benchmark Brent declining to near $101 per barrel (bbl) during the trading session on September 21.

NSE data showed that IndiGo shares surged 2.2% to touch an intraday high of ₹5,030.50 apiece on Monday’s market, in comparison to ₹4,920 apiece at the previous equity market close.

Trading volumes surged past 317K equity shares across NSE and BSE combined, with the company’s stock trading 0.49% higher as of 2:14 pm (IST) at ₹4,942 per share.

Experts predict that the pricing factor and the yields remain strong for IndiGo, with management’s focus on profitability and improving the revenue quality despite cost pressures in the market.

Jet fuel jumps to $194/barrel

International Air Transport Association’s (IATA) Jet Fuel Price Monitor, which draws information from S&P Global’s Platts, showed that the price of aviation turbine fuel (ATF) or jet fuel has risen to touch a weekly average of $194.90 per barrel (bbl) as of the week ended September 18.

In comparison, jet fuel prices have risen 7.4% to a weekly average of $194.90 per bbl, from $181.46 per bbl as of the previous week ended September 11, 2026.

With the pullback in crude oil prices in the current market, investors’ sentiment received some marginal support from the potential for lower jet fuel costs in the near future. However, with the benchmark Brent crude trading above $100 per bbl, cost pressure remained in the market.

The cost of purchasing jet fuel remains the standalone largest expense for an airline in a particular period. Hence, any negative impact on oil prices increases the cost of fuel, and vice versa.

What do Jefferies analysts predict?

Experts from US-based investment firm Jefferies, sharing a constructive outlook, highlighted that the airline is focusing on prioritising profitability over volume expansion despite the high-cost environment due to elevated energy costs in the market.

“While this may moderate near-term industry growth, rationalisation could help maintain pricing discipline and improve the balance between supply and demand,” said Jefferies analysts.

The company’s management retains its growth guidance for capacity addition to be flat in the second quarter results of FY27, and the passenger revenue per available seat kilometre (PRASK) to be at 25%, unchanged from previous estimates.

Jefferies also cited that IndiGo is looking at the recent price hikes as partly sticky, in turn benefiting the medium-term revenue quality of the airline operator. With a strong balance sheet, the analyst firm estimated IndiGo’s growth to remain on track despite cost pressures.

“Cost actions and management transition remain on track, while the strong balance sheet supports IndiGo's FY30 growth ambitions,” said Jefferies analysts.
