Trip.com Group Limited Announces Pricing of Offering of US$1.3 Billion Cash-par

Settled Convertible Senior Notes

SINGAPORE, June 4, 2024—Trip.com Group Limited (Nasdaq: TCOM; HKEX: 9961) (“Trip.com Group” or the “Company”), a leading one-stop travel service provider of accommodation reservation, transportation ticketing, packaged tours, and corporate travel management, today announced the pricing of its previously announced offering (the “Notes Offering”) of US$1.3 billion in aggregate principal amount of convertible senior notes due 2029 (the “Notes”). The Notes have been offered to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The Company has granted the initial purchasers in the Notes Offering an option to purchase up to an additional US$200 million principal amount of the Notes, exercisable for settlement within a 13-day period beginning on, and including, the date on which the Notes are first issued.

The Company plans to use the net proceeds from the Notes Offering for repayment of existing financial indebtedness, expansion of its overseas business, and working capital needs.

Terms of the Notes Offering

The Notes will be general unsecured obligations of the Company and bear interest at a rate of 0.75% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2024. The Notes will mature on June 15, 2029 unless repurchased, redeemed, or converted in accordance with their terms prior to such date. Holders of the Notes may require the Company to repurchase all or part of their Notes for cash on June 15, 2027 or in the event of certain fundamental changes, in each case, at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

Prior to the close of business on the business day immediately preceding the 50th scheduled trading day before the maturity date, the Notes will be convertible at the option of the holders only upon satisfaction of certain conditions and during certain periods. On or after the 50th scheduled trading day before the maturity date until the close of business on the third scheduled trading day immediately preceding the maturity date, holders may convert their Notes at their option at any time. The initial conversion rate of the Notes is 15.0462 American depositary shares (“ADSs”), each currently representing one ordinary share of the Company, per US$1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately US$66.46 per ADS and represents an approximately 32.5% conversion premium over the closing price of the Company’s ADSs on the Nasdaq on June 4, 2024, which was US$50.16 per ADS. The conversion rate of the Notes is subject to adjustment upon the occurrence of certain events.

The Notes contemplate cash-par settlement upon conversion. Upon conversion, the Company will pay cash up to the aggregate principal amount of the Notes being converted and have the right to elect to settle the conversion consideration for amounts in excess of the aggregate principal amount using cash, ADSs, or a combination of cash and ADSs. Holders may elect to receive ordinary shares in lieu of any ADSs deliverable upon conversion, subject to certain conditions and procedures.

In addition, the Company may redeem for cash all but not part of the Notes in the event of certain changes in the tax laws or if less than 10% of the aggregate principal amount of the Notes originally issued remains outstanding at such time, in each case, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the related redemption date. Any redemption may occur only prior to the 50th scheduled trading day immediately preceding the maturity date.

Concurrent Repurchase

Concurrently with the pricing of the Notes Offering, the Company plans to repurchase approximately 6.0 million ADSs in an aggregate amount of approximately US$300 million pursuant to its existing share repurchase plans in off-market privately negotiated transactions effected through one or more of the initial purchasers or their affiliates as its agent, at a price per ADS equal to US$50.16, the last reported sale price per ADS on the Nasdaq on June 4, 2024 (the “Concurrent Repurchase”). The Concurrent Repurchase is expected to facilitate the initial hedges by purchasers of the Notes who desire to hedge their investments in the Notes.

The Concurrent Repurchase will be funded by cash on hand, and is generally expected to offset some of the potential dilution to the holders of the Company’s ordinary shares (including ordinary shares represented by ADSs) upon conversion of the Notes, taking into the account the settlement method of the Notes.

Other Matters

Any repurchase activities of the Company, whether concurrently with the pricing of the Notes or otherwise pursuant to its share repurchase plans, could increase, or reduce the magnitude of any decrease in, the market price of the ADSs and ordinary shares and the price of the Notes.

The Company expects that potential purchasers of the Notes may employ a convertible arbitrage strategy to hedge their exposure in connection with the Notes. Any such activities by potential purchasers of the Notes following the pricing of the Notes and prior to the maturity date could affect the market price of the ADSs and ordinary shares and the trading price of the Notes. The effect, if any, of the activities described in this paragraph, including the direction or magnitude, on the market price of the ADSs and ordinary shares and the trading price of the Notes will depend on a variety of factors, including market conditions, and cannot be ascertained at this time.

The Notes, the ADSs deliverable upon conversion of the Notes, if any, and the ordinary shares represented thereby or deliverable upon conversion of the Notes in lieu thereof have not been registered under the Securities Act, or any state securities laws. They may not be offered or sold within the United States or to U.S. persons, except to qualified institutional buyers in reliance on the exemption from registration provided by Rule 144A under the Securities Act.

The Company expects to close the Notes Offering on or about June 7, 2024, subject to the satisfaction of customary closing conditions.
