INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On February 18, 2026, JIADE LIMITED (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with certain investors named therein (collectively, the “Purchasers”), pursuant to which, the Company agreed to issue and sell, in a registered direct offering (the “Registered Direct Offering”): (i) 3,490,000Class A ordinary shares (the “Class A Ordinary Shares”) of the Company, par value $0.0001 per share (the “Shares”); (ii) pre-funded warrants to purchase up to 8,510,000 Class A Ordinary Shares (the “Pre-Funded Warrants”); and (iii) up to an aggregate of 48,000,000 Class A Ordinary Shares (and/or RD Warrants in lieu thereof) issuable upon the exercise by the Purchasers of their option to purchase such additional Class A Ordinary Shares (and/or RD Warrants in lieu thereof) on or before the 30th calendar day anniversary of the initial closing date on February 19, 2026 (the “Closing Date”) at a purchase price of $0.25 per share (the “Additional Allocation”). The purchase price for each Class A Ordinary Share was $0.25 and the purchase price for each Pre-Funded Warrant was $0.25.

The Pre-Funded Warrants were sold to any purchaser, whose purchase of the Shares in the Registered Direct Offering would otherwise have resulted in such purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, upon election by such purchaser prior to the issuance of any Pre-Funded Warrants, 9.99%) of the outstanding share capital of the Company following the consummation of the Registered Direct Offering. Each Pre-Funded Warrant represents the right to purchase one Class A Ordinary Share at an exercise price of $0.25 per share. The Pre-Funded Warrants were exercisable immediately at any time until exercised in full (subject to the beneficial ownership limitation described above), and were exercised in full by the Purchasers thereof on February 18, 2026.

Upon the closing of the Registered Direct Offering on the Closing Date, the Company received $3 million in gross proceeds, before deducting placement agent fees and offering expenses. The Company intends to use the net proceeds from the Registered Direct Offering for working capital and general corporate purposes.

The Purchase Agreement contains customary representations, warranties, and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties, and termination provisions. Additionally, each of the directors, executive officers, and 5% and greater shareholders of the Company entered into a lock-up agreement, pursuant to which they agreed not to sell or transfer any of the Company securities which they hold, subject to certain customary exceptions, during the ninety (90) day period following the closing of the Registered Direct Offering. In addition, the Company agreed (i) to be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its subsidiaries of Class A Ordinary Shares or Ordinary Share Equivalents (as defined in the Purchase Agreement) involving a Variable Rate Transaction (as defined in the Purchase Agreement) during the forty-five (45) day period after the closing of the Registered Direct Offering; (ii) not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any Class A Ordinary Shares or file any registration statement or amendment or supplement thereto, except as set forth in the Prospectus Supplement (defined below) or a registration statement on Form S-8 during the thirty (30) day period following the closing of the Registered Direct Offering; and (iii) not to consummate a reverse or forward stock split or reclassification of the Class A Ordinary Shares until the thirty (30^th) day anniversary of the Closing Date without the prior written consent of the Purchasers holding a majority in interest of the Shares and Pre-Funded Warrants.

The Shares, the Pre-Funded Warrants, and the Class A Ordinary Shares underlying the Pre-funded Warrants were offered by the Company pursuant to a registration statement on Form F-3 (File No. 333-292574) (the “Registration Statement”), previously filed and declared effective by the U.S Securities and Exchange Commission (the “Commission”) on January 13, 2026, the base prospectus filed as part of the Registration Statement, and the prospectus supplement dated February 18, 2026 (the “Prospectus Supplement”).

On February 18, 2026, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Univest Securities, LLC (“Univest” or the “Placement Agent”), pursuant to which the Company engaged Univest as the exclusive placement agent in connection with the Registered Direct Offering. The Placement Agent agreed to use its reasonable best efforts to arrange for the sale of the Shares and the Pre-Funded Warrants. In addition, under the Placement Agency Agreement, the Company agreed to pay the Placement Agent a placement agent fee in cash equal to seven percent (7.0%) of the aggregate gross proceeds raised from the sale. The Company also agreed to reimburse the Placement Agent for its out-of-pocket expenses in connection with the Registered Direct Offering in an amount not to exceed $80,000.

The foregoing summaries of the Pre-Funded Warrants, the Placement Agency Agreement, and the Purchase Agreement do not purport to be complete and are subject to, and qualified in their entirety by, such documents filed as Exhibits 4.1, 10.1, and 10.2, respectively, hereto and incorporated by reference herein. A copy of the press release related to the Registered Direct Offering entitled “JIADE LIMITED Announces Pricing of $3 Million Registered Direct Offering” is furnished as Exhibit 99.1 hereto and is incorporated by reference herein.

Copies of the opinions of Maples and Calder (Hong Kong) LLP and Hunter Taubman Fischer & Li LLC relating to the legality of the issuance and sale of the Shares and the Pre-Funded Warrants are filed as Exhibits 5.1 and 5.2 hereto, respectively.

This Report is incorporated by reference into the registration statement on Form F-3 (File No. 333-292574) of the Company, filed with the Commission, to be a part thereof from the date on which this report is submitted, to the extent not superseded by documents or reports subsequently filed or furnished.
