First in Asia: PTTEP to Offer USD-Denominated Digital Debentures to Retail Investors via Paotang App — Expected Launch May 2026

Krungthai Bank has partnered with PTT Exploration and Production Public Company Limited (PTTEP) to pioneer a new frontier in digital capital markets, introducing Asia's first USD-denominated digital debentures offering to retail investors through the Bond Wallet on the Paotang app.

The initiative opens the door for Thai investors to gain equal access to USD-denominated fixed-income assets issued by a fundamentally strong company with proven growth potential — supporting portfolio diversification and enhanced return opportunities, with a minimum investment of USD 1,000 and no maximum subscription cap.

PTTEP, along with the digital debentures to be offered, has been assigned a credit rating of AAA with a Stable outlook — the highest achievable level — by TRIS Rating as of 16 March 2026. The bonds will be issued in registered, senior unsecured and unsubordinated form, with a debenture holder representative, a tenor of 5 years, and a fixed coupon of 4.50% per annum, payable semi-annually. The subscription period is expected to run from 18 – 21 May 2026, exclusively through the Bond Wallet on the Paotang app by Krungthai Bank.

Mr. Rawin Boonyanusasna, Head of Global Markets Group at Krungthai Bank, stated that on the occasion of Krungthai’s 60th anniversary, “Steps Toward Endless Possibilities,” we reaffirm our commitment to developing world-class investment products and services that comprehensively meet investors’ needs. We continue enhancing investment capabilities through digital platforms with the development of the USD Bond Wallet, which is a landmark initiative in broadening onshore access to USD-denominated investments for Thai investors — a segment experiencing significant and growing demand. Through this platform, investors can seamlessly access high-grade, USD-denominated digital debentures from creditworthy Thai issuers, supported by 24-hour secondary market liquidity provided by Krungthai Bank to ensure greater flexibility and efficiency in portfolio management.

Investors interested in subscribing to PTTEP’s digital USD debentures can prepare in advance through the following steps:

1. Download and register on the Paotang app.
2. Activate the Bond Wallet on the Paotang app and complete the investor suitability assessment.
3. Open a foreign currency deposit account with Krungthai Bank, or set up a Global Savings account via the Krungthai NEXT app, and link it to the Bond Wallet on the Paotang app as the designated account for receiving interest and principal redemption proceeds. Existing Krungthai Travel Card holders or those with an existing Global Savings account do not need to open a new account and can simply link their existing Global Savings to the Bond Wallet.
4. Convert THB to USD in your Global Savings account in advance of the subscription period.

In addition, investors can convert and hold USD in their Global Savings account on a 24/7 basis, earning a deposit rate of 2.25% per annum (as of 30 April 2026) while awaiting the bond subscription. Once invested, coupon payments will be credited automatically to the linked Global Savings account, compounding long-term wealth creation.

The Company is currently in the process of filing the registration statement and draft prospectus with the Securities and Exchange Commission of Thailand (SEC). The filing has not yet become effective. Investors are advised to refer to the prospectus for full details at www.sec.or.th and www.krungthai.com, or contact Krungthai Bank at 02-111-1111
