Welcome to our dedicated page for Birchtech SEC filings (Ticker: BCHT), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Birchtech Corp.'s SEC filings document an operating company focused on specialty activated carbon technologies for sustainable air and water treatment. The filings cover common stock registered on NYSE American, public offering registration statements, underwriting agreements, completed equity financing events, and related capital-structure disclosures.
Material-event reports also record governance and corporate matters, including executive finance leadership, annual meeting procedures, shareholder proposal and director nomination mechanics, and patent-related litigation outcomes. The filing record ties these disclosures to Birchtech's SEA® mercury-capture technology, water treatment platform, intellectual property portfolio, and public-company reporting obligations.
Birchtech Corp. reported stronger first-quarter activity but remains loss-making. Revenue rose to $4.24 million from $3.22 million, driven by higher product sales, while license revenue dropped to zero. Gross profit was $1.38 million, and the company recorded a net loss of $1.35 million, or $0.06 per share, compared with a $1.68 million loss a year earlier.
Liquidity improved significantly after a February–March underwritten stock offering of 6.85 million shares that generated gross proceeds of $16.44 million. Cash increased to $14.75 million at March 31, 2026, up from $2.25 million at year-end, and stockholders’ equity turned positive at $11.17 million. Management now believes existing cash and expected revenue can fund operations for at least 12 months.
The balance sheet includes a related-party profit share liability of $7.09 million, tied to future net litigation proceeds from enforcing Birchtech’s mercury-control patents. A final judgment of $78.40 million (including pre-judgment interest) was entered in December 2025 against certain CERT defendants, but it has not been recognized as an asset because collection remains uncertain and the defendants have appealed. Birchtech is also advancing water-treatment technologies for PFAS and PFOS, supported by new design centers in Pennsylvania and North Dakota.
Birchtech Corp. filed an amendment to its earlier report to disclose final compensation terms for its new Chief Financial Officer, Michael Mioska. Effective May 8, 2026, Mioska will provide full-time CFO services to Birchtech through an employer-of-record arrangement with Canadian firm Oyster HR Inc.
Under this structure, he is employed by Oyster HR Inc. and assigned to Birchtech. He will receive an annual base salary of $425,000 CAD, described as approximately $312,000 USD, and will be eligible for discretionary annual cash bonuses. The engagement is for an indefinite term, subject to standard notice and termination provisions, and all other terms from the original report remain unchanged.
Birchtech Corp. filed an initial Form 3 insider report for Mioska Michael David, who serves as Chief Financial Officer. The filing, as provided, does not list any equity holdings or report any buy, sell, or other insider transactions for him.
Birchtech Corp. has appointed experienced finance executive Michael Mioska, CPA, MBA, as Chief Financial Officer. He has over 20 years of accounting, audit and financial reporting experience across the United States and Canada and has consulted for Birchtech since 2023.
Mioska has worked closely with Birchtech’s finance team, giving him deep familiarity with the company’s operations, systems and strategic priorities. Management expects his capital markets, M&A and reporting expertise to support the next phase of growth in Birchtech’s specialty activated carbon air and water treatment businesses.
Birchtech Corp. set the date for its 2026 Annual Meeting of Stockholders for Thursday, July 23, 2026, to be held as a virtual-only meeting conducted via remote communications. The company will provide the exact time, access details, and agenda items in its upcoming proxy statement.
Because no annual meeting was held in 2025, stockholders seeking to include proposals in the 2026 proxy materials under Rule 14a-8 must deliver them to the company’s Corsicana, Texas headquarters by the close of business on May 26, 2026. The same deadline applies to stockholder proposals or director nominations submitted outside Rule 14a-8, all of which must satisfy the advance notice provisions in Birchtech’s amended and restated bylaws.
Birchtech Corp. files its annual report outlining its specialty activated carbon business and the main risks it faces. The company supplies patented SEA® mercury-capture technology to coal-fired power plants and is building a water treatment platform focused on PFAS “forever chemicals.” It is investing in two Design Centers to develop reactivated granular activated carbon and ion exchange resins and plans a regional thermal reactivation facility. Birchtech reports a concentrated customer and supplier base, ongoing patent litigation and inter partes review activity, significant reliance on U.S. environmental rules such as MATS and PFAS standards, a 1-for-5 reverse stock split, and recent uplisting of its common stock to the NYSE American.
Birchtech Corp. expanded its recent stock sale through a partial use of the underwriters’ over-allotment option. The company originally sold 6,250,000 common shares at $2.40 per share, generating gross proceeds of $15.0 million.
On March 17, 2026, the underwriters bought an additional 600,000 shares at the same price, adding approximately $1.4 million of gross proceeds. In total, 6,850,000 shares have been issued in the offering, with aggregate gross proceeds of about $16.4 million and 337,500 over-allotment shares still available.
Birchtech Corp. President and CEO Richard MacPherson reported an open-market purchase of the company’s common stock. He bought 312,500 shares at $2.40 per share for a total of $750,000 in a public offering of 6,250,000 shares that closed on February 27, 2026.
Following this transaction, his directly owned stake increased to 2,955,095 common shares. The share amounts in the filing reflect Birchtech’s 1-for-5 reverse stock split that became effective on December 26, 2025.
Birchtech Corp. completed an underwritten public offering of 6,250,000 shares of common stock at $2.40 per share, generating approximately $13.1 million in net proceeds. Underwriters also have a 30‑day option to buy up to 937,500 additional shares, which would lift net proceeds to about $15.2 million if fully exercised.
The company plans to use the cash, together with existing funds, for ongoing operating expenses, working capital and other general corporate purposes. Birchtech’s CEO purchased $750,000 of stock in the deal, or 312,500 shares, and directors and executive officers agreed to a 90‑day lock‑up. The offering supports Birchtech’s uplisting, as its common stock was approved for trading on the NYSE American under the symbol BCHT while remaining listed on the Toronto Stock Exchange.
Birchtech Corp. is offering 6,250,000 shares of common stock in a primary offering at $2.40 per share. The offering is expected to produce proceeds to the company of $13,950,000 before expenses, with a 30-day underwriter option for an additional 937,500 shares. The company reports 19,455,966 shares outstanding prior to the offering and 25,705,966 shares outstanding immediately after the offering (assuming no exercise of the option). The prospectus gives effect to a 1-for-5 reverse stock split effective December 26, 2025 and notes expected NYSE American trading under the symbol BCHT beginning February 26, 2026. The Chief Executive Officer intends to purchase $750,000 (an aggregate of 312,500 shares) in the offering.
