Birchtech Corp. SEC Filings

Birchtech Corp. is asking stockholders to vote at a fully virtual annual meeting on July 23, 2026. Stockholders will elect four directors, ratify Rosenberg Rich Baker Berman, P.A. as auditor, cast an advisory “say‑on‑pay” vote on executive compensation, and consider cutting authorized common shares from 150,000,000 to 50,000,000 to help reduce Delaware franchise taxes. The record date is June 10, 2026, when 26,305,966 common shares were outstanding, and voting can be completed online, by phone, by mail, or during the meeting.

Birchtech Corp. is holding its annual meeting virtually on July 23, 2026 to vote on four director nominees, ratify Rosenberg Rich Baker Berman, P.A. as auditor, approve an advisory say-on-pay, and approve an amendment to reduce authorized common shares from 150,000,000 to 50,000,000. The board set the record date as June 10, 2026, when 26,305,966 shares were outstanding. The proxy materials describe recent executive employment amendments: the CEO’s term extended through May 31, 2030 with a $500,000 retention bonus and continued base salary of $1,000,000; the COO received a $250,000 retention bonus. The proxy explains voting methods, quorum rules, and board governance policies including a Majority Voting Policy and Audit Committee composition.

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.
