Insights

Tantech raises $2.15M via unit deal with attached warrants.

Tantech Holdings Ltd completed a registered direct offering with a concurrent Regulation S private placement, selling 7,166,671 units at $0.30 each for about $2.15 million in gross proceeds. Each unit combines equity with Series E and Series F warrants.

The warrants allow investors to buy three shares per warrant series at exercise prices of $0.30 and $0.35, respectively, potentially adding future share issuance if exercised. Officers and directors agreed to a 60‑day lock-up after closing, which temporarily limits insider sales.

The company indicates proceeds will support general corporate purposes and working capital. Actual dilution and trading impact will depend on investor exercise of the warrants and future resale activity under the planned registration statements tied to the existing Form F‑3 shelf.

registered direct offering financial
"the Company announced the pricing and closing of a registered direct offering and concurrent private placement"
A registered direct offering is a way for a company to sell new shares of its stock directly to select investors with regulatory approval. This method allows the company to raise funds quickly and efficiently without needing a public auction, similar to offering exclusive access to a limited number of buyers. For investors, it often provides an opportunity to purchase shares at a favorable price, while giving the company immediate access to capital.
concurrent private placement financial
"pricing and closing of a registered direct offering and concurrent private placement with certain investors"
A concurrent private placement is a sale of a company’s shares or bonds directly to a select group of investors that happens at the same time as another financing action or offering. Think of it as quietly selling a block of tickets to a few people while a larger ticket drive is underway; it raises cash quickly but can change ownership proportions, dilute existing shareholders and affect share price, so investors watch it as a sign of funding needs and potential value shifts.
Regulation S regulatory
"The Private Placement was made pursuant to Regulation S under the Securities Act of 1933"
Regulation S is a set of rules that allows companies to sell securities (like shares or bonds) to investors outside the United States without having to follow all U.S. securities laws. It matters because it makes it easier for companies to raise money from international investors while still complying with U.S. regulations.
lock-up agreements financial
"officers and directors of the Company entered into lock-up agreements pursuant to which they have agreed"
A lock-up agreement is a contract that prevents company insiders—founders, employees, and early investors—from selling their shares for a set period after a public stock offering. It matters to investors because it keeps a large block of shares off the market temporarily; when the lock-up ends, those holders can sell and this increased supply can cause the stock price to fall, similar to a timed release that suddenly opens a valve.
registration rights agreement financial
"pursuant to a registration rights agreement with the Investors, it agreed to file one or more registration statements"
A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.
shelf registration statement regulatory
"pursuant to the Company’s effective shelf registration statement on Form F-3"
A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.

EXPLANATORY NOTE

 

On March 31, 2026, Tantech Holdings Ltd (the “Company”) announced the pricing and closing of a registered direct offering and concurrent private placement with certain investors (the “Investors”) for aggregate gross proceeds of approximately $2.15 million.

 

The Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with the Investors, pursuant to which the Company agreed to issue and sell Class A Shares, no par value per share (the “Common Shares”) in a registered direct offering (the “Registered Direct Offering”), together with warrants in a concurrent private placement (the “Private Placement”).

 

The transactions consisted of the sale of 7,166,671 Common Units, each consisting of (i) one Common Share, (ii) one Series E Common Warrant to purchase three Common Shares at an exercise price of $0.30 per share (the “Series E Common Warrants”), and (iii) one Series F Common Warrant to purchase three Common Shares at an exercise price of $0.35 per share (the “Series F Common Warrants”). The offering price per Common Unit was $0.30. The Company stated that it expects to use the net proceeds from the offerings, together with its existing cash, for general corporate purposes and working capital. For the purposes of British Virgin Islands law, the issuance of the Common Shares will be effective upon entry of the relevant shareholder in the Company’s register of members.

 

Concurrently with the execution of the Securities Purchase Agreement, the officers and directors of the Company entered into lock-up agreements (the “Lock-Up Agreement”) pursuant to which they have agreed, among other things, not to sell or dispose of any Common Shares which are or will be beneficially owned by them for sixty (60) days following the closing of the offering.

 

The Registered Direct Offering was made pursuant to the Company’s effective shelf registration statement on Form F-3 (File No. 333-274274), which was declared effective by the U.S. Securities and Exchange Commission (“SEC”) on September 11, 2023. The Private Placement was made pursuant to Regulation S under the Securities Act of 1933, as amended, and the securities were offered only to non-U.S. persons. The Company also disclosed that, pursuant to a registration rights agreement with the Investors, it agreed to file one or more registration statements covering the resale of the Common Shares and the shares issuable upon exercise of the Series E Common Warrants and Series F Common Warrants.
