Birchtech Corp. 8-K

What Happened Birchtech Corp. (BCHT) filed an 8-K reporting that it executed a 1-for-5 reverse stock split of its common stock. The company filed a Certificate of Amendment with the Delaware Secretary of State on December 23, 2025, making the reverse split effective December 26, 2025. The common stock is expected to begin trading on a split-adjusted basis on December 31, 2025; the trading symbol will remain BCHT, though the OTCQB will temporarily append a “D” to the symbol for 20 business days.

Key Details

• Reverse split ratio: 1-for-5 — every 5 issued and outstanding shares converted into 1 share.
• Effective date/filed: Certificate filed Dec 23, 2025; effective Dec 26, 2025; trading adjusted Dec 31, 2025.
• CUSIP change: new CUSIP for common stock is 59833H200.
• Fractional shares: no fractional shares will be issued; any fractional share resulting from the split will be rounded up to the next whole share.
• Other effects: the reverse split does not change authorized shares or par value; proportional adjustments will be made to outstanding equity awards, warrants, options, etc. Transfer Online, Inc. will act as exchange agent and will provide instructions to holders of certificated shares; book-entry and brokerage account holdings will be adjusted electronically per brokers’ processes.

Why It Matters A reverse stock split reduces the number of outstanding shares and increases the per-share price proportionally, while leaving each holder’s percentage ownership unchanged (aside from rounding). Investors should note the new CUSIP, the temporary OTCQB “D” designation, and that outstanding options/warrants will be adjusted. Shareholders holding certificates should follow instructions from the transfer agent; holders in brokerage accounts should confirm how their brokers will handle the split.
