STOCKHOLDERS’ EQUITY | 11. STOCKHOLDERS’ EQUITY AUTHORIZED CAPITAL The Company is authorized to issue 500,000,000 shares of common stock, $0.001 par value, and 40,000,000 shares of preferred stock, $0.001 par value. The holders of the Company’s common stock are entitled to one vote per share. The preferred stock is designated as follows: 20,000,000 shares to Series A Convertible Preferred Stock; 10,000 shares to Series B Convertible Preferred Stock; 250,000 shares to Series C Convertible Preferred Stock; 13 shares to Series D Convertible Preferred Stock; and 19,739,987 undesignated shares. OMNIBUS INCENTIVE PLANS On September 7, 2018, the Board of the Company, as well as a majority of the Company’s shareholders approved the Company’s 2018 Incentive Compensation Plan (the “2018 Plan”), which enables the Company to grant stock options, restricted stock, dividend equivalents, stock payments, deferred stock, restricted stock units, stock appreciation rights, performance share awards, and other incentive awards to associates, directors, consultants, and advisors of the Company and its affiliates, and to improve the ability of the Company to attract, retain, and motivate individuals upon whom the Company’s sustained growth and financial success depend, by providing such persons with an opportunity to acquire or increase their proprietary interest in the Company. Stock options granted under the 2018 Plan may be non-qualified stock options or incentive stock options, within the meaning of Section 422(b) of the Internal Revenue Code of 1986, except that stock options granted to outside directors and any consultants or advisers providing services to the Company or an affiliate shall in all cases be non-qualified stock options. The option price must be at least 100% of the fair market value on the date of grant and if issued to a 10% or greater shareholder must be at least 110% of the fair market value on the date of the grant. The 2018 Plan is to be administered by the Compensation Committee of the Board, which shall have discretion over the awards and grants thereunder. The aggregate maximum number of shares of common stock for which stock options or awards may be granted pursuant to the 2018 Plan is 5,000,000, adjusted as provided in Section 4 of the 2018 Plan. No awards may be issued on or after September 7, 2028. As of December 31, 2024, and 2023, options to purchase 986,165 and 936,245 shares of options were outstanding, respectively. As of December 31, 2024, and 2023 4,974,178 and 3,619,555 shares of common stock, respectively, were outstanding to employees and members of the Board of Directors of the Company. As of December 31, 2024 and 2023, there were 2,025,822 and 2,756,384 securities available for future issuance under the 2018 Plan, respectively. PUBLIC OFFERING In February 2023, the Company completed an underwritten registered public offering of 8,333,333 shares of its common stock at a public offering price of $12.00 per share. The Company received approximately $100,000 in gross proceeds from the public offering and $94,766 in net proceeds after deducting the underwriting discount and offering expenses paid by the Company. The public offering was made pursuant to our automatic shelf registration statement on Form S-3 filed with the SEC on January 6, 2021, and prospectus supplement dated February 8, 2023. Barclays acted as the sole book-running manager for the offering. H.C. Wainwright & Co., Roth Capital Partners and ThinkEquity acted as co-managers for the offering. The underwriters did not exercise the over-allotment granted to them in connection with the offering. BLINK CHARGING CO. Notes to Consolidated Financial Statements (in thousands, except for share and per share amounts) 11. STOCKHOLDERS’ EQUITY – CONTINUED AT-THE-MARKET OFFERING On September 2, 2022, the Company entered into a Sales Agreement (“Sales Agreement”) with Barclays Capital Inc., BofA Securities, Inc., HSBC Securities (USA) Inc., ThinkEquity LLC, H.C. Wainwright & Co., LLC and Roth Capital Partners, LLC (the “Agents”) to conduct an “ATM” equity offering program pursuant to which the Company may issue and sell from time to time shares of our common stock, having an aggregate offering price of up to $250,000 through the Agents, as the Company’s sales agents. The Company currently anticipates using the net proceeds from the sale of its shares of common stock under the ATM program to supplement our operating cash flows to fund EV charging station deployment and growth plans. The Company also plans to use any remaining proceeds it receives for working capital and other corporate purposes. The amounts and timing of our use of the net proceeds will depend on a number of factors, such as the timing and progress of our EV charging station deployment efforts, the timing and progress of any partnering and collaboration efforts and technological advances. On November 16, 2023, the Company entered into an Amendment to Sales Agreement, effective as of November 2, 2023 (the “Amendment”), with Barclays Capital Inc., BofA Securities, Inc., HSBC Securities (USA) Inc., H.C. Wainwright & Co., LLC, Roth Capital Partners, LLC and ThinkEquity LLC (the “Agents”), amending the Sales Agreement entered into between the Company and the Agents, dated as of September 2, 2022 (the “Sales Agreement”), relating to the “at-the-market” offering program pursuant to which the Company may issue and sell from time to time shares of its common stock, par value $0.001 per share, having an aggregate offering price of up to $250,000 through the Agents, as the Company’s sales agents. The Amendment revises the term “Registration Statement” as used in the Sales Agreement to the Company’s new shelf registration statement on Form S-3, as amended (File No. 333-275123), and revises the term “Prospectus Supplement” as used in the Sales Agreement to the Company’s prospectus supplement dated November 2, 2023, relating to the “at-the-market” offering program contemplated by the Sales Agreement.

Notes to Consolidated Financial Statements (in thousands, except for share and per share amounts) 11. STOCKHOLDERS’ EQUITY – CONTINUED STOCK-BASED COMPENSATION The Company recognized stock-based compensation expense related to common stock, stock options and warrants for the years ended December 31, 2024, 2023, and 2022, of $3,525, $22,039, $15,913, respectively, which is included within compensation expense on the consolidated statement of operations. As December 31, 2024, there was $2,709 of unrecognized stock-based compensation expense that will be recognized over the weighted average remaining vesting period of 1.11 years. On July 29, 2022, Michael D. Farkas, the Company’s Chairman and Chief Executive Officer, and other senior executives of the Company who are responsible for the acquisition and integration of SemaConnect were granted one-time performance-based restricted stock awards under the Company’s 2018 Incentive Compensation Plan. A total number of 590,458 shares of common stock, with a market value on the grant date of $12,000, were awarded to the executives. The agreements provide that Messrs. Farkas, Brendan S. Jones, President, Michael P. Rama, Chief Financial Officer, Aviv Hillo, General Counsel, and Harjinder Bhade, Chief Technology Officer, will each receive 472,367, 47,237, 23,618, 23,618 and 23,618 shares of common stock, respectively. The awards of performance-based restricted stock are intended to provide an appropriate incentive structure for the executive management team of the Company to integrate and commercialize the SemaConnect acquisition given the transformational nature of the acquisition in a way that is aligned with stockholder interests. The awards of these performance-based restricted stock become vested based on a series of six performance hurdles that must be achieved before the third anniversary of the grants, as described in greater detail below. In addition to the closing of the SemaConnect acquisition with certain cost savings as the initial 20% vesting event, the vesting of the remaining 80% of the restricted stock is generally determined based on the (i) integration of SemaConnect’s hardware and software platforms, (ii) integration of its business processes, (iii) integration of its human capital processes, (iv) delivery and execution of a product rationalization roadmap and new production ready units for UL certification, and (v) our common stock’s closing price reaching on average for a period of ten consecutive trading days a price of $23.78, which is 50% over the price paid by us to SemaConnect shareholders in the acquisition, in each case without regard to the order of achieving the foregoing hurdles. The Board has discretion to determine when each performance hurdle has been achieved and to accelerate awards pursuant to the program. WARRANT AND OPTION VALUATION The Company has computed the fair value of certain warrants and options granted using the Black-Scholes option pricing model. Option forfeitures are reduction of previous expensed amount at the time of occurrence. The expected term used for options issued is the estimated period of time that options granted are expected to be outstanding. The Company utilizes the “simplified” method to develop an estimate of the expected term of “plain vanilla” employee option grants. The Company is utilizing an expected volatility figure based on a review of the historical volatility of the Company over a period equivalent to the expected life of the instrument being valued. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.
