Disclosures

Cheonbo's subsidiary Cheonbo BLS has resolved to issue KRW 78.2 billion of unregistered, unguaranteed private convertible bonds (1.0% coupon / 4.0% yield-to-maturity, maturing 2033-05-29) to Mirae Asset Renaissance New Energy PEF. Proceeds will fund facility investment (KRW 54.74B) and working capital (KRW 23.46B). The conversion price is set at KRW 39,463 per share, potentially issuing up to 1,981,603 new shares (26.07% of total). Refixing terms include a performance-linked adjustment if FY2029 EBITDA falls below KRW 80 billion (floor at 50% of initial conversion price), plus standard dilution protections. A 30% call option (up to KRW 23.46B) and put option exercisable from year 5 are attached, with a qualified IPO covenant.

The company will host an IR event on June 4, 2026, from 15:30 to 17:00 in Yeouido, targeting institutional investors and analysts. The session will cover business progress and outlook for the Cube Prober and Memory/SOC Test Handler businesses, along with growth opportunities in the semiconductor inspection market. Sponsored by Samsung Securities, the event will feature a presentation and Q&A format. IR materials will be posted on the company's IR page and KRX KIND system on the event date.

The company signed a single supply contract to deliver semiconductor manufacturing equipment to SK Hynix for KRW 21.534 billion (excluding VAT), equivalent to about 6.13% of its most recent annual revenue. The contract runs from May 20, 2026 to January 11, 2027, with payment structured as 90% on equipment delivery (FOB) and 10% after setup completion. No down payment is involved, and the company has a track record of similar contracts with SK Hynix over the past three years. The deal reinforces the company's position as a key equipment supplier to SK Hynix amid ongoing memory capex.

The company will hold an Investor Relations event on May 28-29, 2026 in Seoul, targeting major domestic institutional investors. The Non-Deal Roadshow, sponsored by Korea Investment & Securities, will consist of investor meetings covering Q1 2026 earnings results and key business updates. IR materials will be published on May 27 via the KRX IR repository and the company website. This is a routine institutional outreach rather than a transactional event, so direct share-price impact should be limited absent new disclosures during the meetings.

The company has resolved to issue KRW 100 billion in unregistered, coupon-bearing, unsecured, non-detachable private bonds with warrants (BW) qualifying as hybrid capital securities. Proceeds will fund facility investment (KRW 40B), operating capital (KRW 20B), and acquisition of other companies' securities (KRW 40B). The bonds carry a 0.0% coupon and 0.0% maturity yield with a 30-year maturity (June 8, 2056), but a step-up clause adds 3.0% compounded annually after year 3, with an additional 1.0% added each subsequent year. The issuer holds a call option exercisable from year 3 onward (and quarterly thereafter), as well as a separate call right tied to accounting standard changes; bondholders have no put option. Maturity can be extended at the issuer's discretion, supporting equity classification under K-IFRS.

The company decided to issue KRW 100 billion of private, non-guaranteed, non-separable bonds with warrants, structured as hybrid capital securities (perpetual-style) with a 30-year maturity (June 8, 2056) and 0.0% coupon. Proceeds will fund facilities (KRW 40B), working capital (KRW 20B), and acquisition of other corporations' securities (KRW 40B). The warrant exercise price is KRW 267,747 per share at 100% of the base price, potentially issuing up to 373,486 new common shares — 5.34% of outstanding stock. The issuer holds an early redemption right starting 3 years after issuance, and notably the exercise price will NOT be adjusted downward for share price declines (no refixing).
