Fine M-Tec CB & EB Anatomy: The 8,455,673-Share Triple Overhang

One Fine M-Tec CB plus two affiliate EBs (Fine Technix, Fine D&C) — how the group uses Fine M-Tec stock as collateral, and the potential dilution risk this creates

Notice: I am a beginner investor with limited experience. This post is NOT a recommendation to buy or sell any security. It is a personal record of my study, written so I can revisit it later. All investment decisions and their consequences are the investor's own responsibility.

0. Bottom line first

Fine M-Tec's potential share overhang does not come from a single CB — it comes from three sources: (1) Fine M-Tec's own 9th-series CB (KRW 30B → 5,362,888 new shares), (2) affiliate Fine Technix's 10th-series EB (KRW 11.6B → 1,657,142 shares), and (3) affiliate Fine D&C's 10th-series EB (KRW 8.7B → 1,435,643 initially, of which 412,540 have already been exchanged, leaving 1,023,103). The total potentially marketable shares are 8,455,673 on an as-issued basis (CB 5,362,888 + EB 3,092,785), or 8,043,133 net of shares already exchanged.

Interpretation: The key distinction is that CB and EB hit shareholders differently. A CB issues new shares and directly dilutes existing equity. An EB does NOT issue new shares — instead, existing shares held by an affiliate get released into the market. Both increase free float and pressure the stock, but only the CB increases the total share count. What personally bothers me more is that Fine Technix and Fine D&C are using their Fine M-Tec stake as collateral for their own fundraising. If those affiliates' businesses are weak, Fine M-Tec stock could keep getting pulled in as the group's financial safety net.

The CB increases total shares outstanding by issuing new stock; each EB releases existing shares held by an affiliate into the market. Different mechanics, same direction of pressure on Fine M-Tec's supply-demand.

1.1 CB vs EB

CB

Convertible Bond — direct dilution

The issuing company (Fine M-Tec) raises money and grants holders the right to convert into newly issued shares at a preset conversion price after a set period. Conversion increases total shares outstanding and dilutes existing shareholders' ownership.

EB

Exchangeable Bond — shadow dilution (overhang)

The issuer (Fine Technix / Fine D&C) promises to exchange the bond for shares of another company (Fine M-Tec) that it already holds. No new Fine M-Tec shares are issued, but a large long-held block can be released into the market, sharply increasing the public float.

Official fact: Source data are reconstructed from disclosures on Korea's Financial Supervisory Service DART system. Fine D&C EB remaining = initial 1,435,643 − 412,540 already exercised = 1,023,103.

2. Internally generated dilution — Fine M-Tec 9th-series CB

2.1 Issuance details: KRW 30B

Official fact: Fine M-Tec issued a "9th-series bearer, unsecured, privately placed convertible bond" to fund itself. Total size is KRW 30B, and the stated use of proceeds is "facility investment." Specifically, it will fund new capex to address the foldable market and to "strengthen ultra-precision laser production capacity (CAPA)." The CB was taken by mezzanine funds set up by securities firms.

2.2 Conversion mechanics and dilution effect

  • Conversion price: KRW 5,594 per share.
  • Potential new shares: If fully converted, 5,362,888 new common shares would be issued.
  • Dilution calculation: Against Fine M-Tec's recently disclosed total share count of 37,146,003, full conversion lifts the total to 42,508,891 shares.
  • Dilution rate: ~12.6% (5,362,888 / 42,508,891).
  • Conversion request period: Not explicitly stated in the available materials. By convention, requests typically begin 1 year after issuance and end 1 month before maturity.

2.3 Refixing — the hidden amplifier

Interpretation: A standard "refixing" clause in Korean CBs adjusts the conversion price downward if the stock price falls or if the company subsequently issues equity-linked securities at a lower price. That means the 5,362,888 figure based on KRW 5,594 is a floor, not a ceiling. If the stock languishes or additional financing happens at lower prices, the same KRW 30B principal can convert into more shares than 5,362,888. The headline dilution number should be read conservatively.

3. Externally generated dilution — affiliate EBs

3.1 The interconnected corporate structure

Interpretation: Fine M-Tec sits inside a tightly linked corporate group together with Fine Technix and Fine D&C. The two affiliates have used their Fine M-Tec holdings as financial assets to fund themselves. Read structurally, this is a sophisticated group-level treasury strategy: rather than having Fine M-Tec carry the entire fundraising burden alone, affiliates monetize their Fine M-Tec stake to solve their own balance-sheet problems.

Official fact: The stated use of proceeds for the Fine Technix EB includes repaying borrowings of affiliates Fine M-Tec and Fine D&C. This is clear evidence that the three companies are tied together in a single financial transaction.

3.2 Fine Technix 10th-series EB — liquefying the stake

  • Issue size / purpose: KRW 11.6B · "debt repayment."
  • Instrument: 10th-series bearer, coupon-bearing, unsecured, privately placed exchangeable bond.
  • Exchange asset: Fine M-Tec common stock.
  • Exchange price: KRW 7,000 per share.
  • Exchangeable shares: 1,657,142 Fine M-Tec shares (4.48% of Fine M-Tec's total shares at issuance).
  • Exchange request period: 2025-08-14 to 2028-06-14.

Official fact: The issuer, Fine Technix, was recently flagged for designation as a "company with inadequate disclosure." This is unrelated to this EB itself but is a qualitative risk factor for disclosure reliability.

3.3 Fine D&C 10th-series EB — the risk that has already materialized

  • Issue size: KRW 8.7B (10th-series bearer, coupon-bearing, unsecured, privately placed EB).
  • Exchange asset: Fine M-Tec common stock.
  • Exchange price: KRW 6,060 per share.
  • Initial exchangeable shares: 1,435,643 Fine M-Tec shares.
  • Already exercised: 412,540 shares.
  • Remaining overhang: 1,435,643 − 412,540 = 1,023,103 shares.

Interpretation: The most important point about this EB is that the overhang risk is no longer theoretical — exchanges have started. That is a strong signal that bondholders have enough incentive to exchange and sell Fine M-Tec into the market. As long as Fine M-Tec's price stays above KRW 6,060, the remaining Fine D&C balance — and by extension the Fine Technix EB and Fine M-Tec CB — should be considered live overhang risks.

4. Overall dilution assessment

4.1 Quantifying total overhang — scenario analysis

Separating direct dilution from new share issuance and float increase from existing share release:

  • Fine M-Tec CB (new shares): 5,362,888
  • Fine Technix EB (existing shares): 1,657,142
  • Fine D&C EB (remaining existing shares): 1,023,103
  • Total on remaining basis: 8,043,133 shares

Table 2 — Scenario impact on share supply

ScenarioTotal shares outstandingChange in shares outstandingEquity dilution (%)Public floatFloat increaseTotal potential float growth (%)
Current (baseline)37,146,003--25,759,732--

Scenario 2: Full EB exchange37,146,003--—+2,680,245—
Scenario 3: All securities converted/exchanged42,508,891+5,362,88812.6%33,802,965+8,043,133+31.2%

Official fact: Baseline share count and float are from disclosures as of 2025-08-06. Float excludes major-shareholder and related-party holdings and treasury stock. Each scenario assumes all target shares of the relevant securities are released into the market.

4.2 Risk timetable — exercise windows

  • Fine D&C EB: Exchanges have already begun — immediate overhang risk.
  • Fine Technix EB: 2025-08 through 2028-06 — medium-to-long-term supply pressure.
  • Fine M-Tec CB: Convertible typically from 1 year after issuance — medium-to-long-term dilution pressure.

5. Personal note — what bothers me

Overall, Fine M-Tec is being used somewhat like collateral by Fine D&C and Fine Technix. The two affiliates have additional EBs backed by their Fine M-Tec holdings, and Fine M-Tec itself has issued a CB for facility investment on top of that. Both types of bonds end up adding to market supply, but EBs release existing shares (likely picked up by private funds), while the CB also issues brand-new shares that directly dilute existing shareholders — that mechanical difference is worth keeping in mind.

Interpretation: Maybe not a huge concern in isolation. What I don't love is that Fine D&C and Fine Technix are leaning on Fine M-Tec as collateral. Their own business situations don't look strong, so further digging is warranted. Short-term, watch for additional exchanges of the Fine D&C EB; medium-to-long-term, monitor the exercise timing of the Fine Technix EB and Fine M-Tec CB.
