Statement on Schedule 13D

This Amendment No. 1 (“Amendment No. 1”) supplements and amends the Schedule 13D that was originally filed on August 26, 2021 (the “Original Schedule 13D”). This Amendment No. 1 relates to the beneficial ownership of common stock, par value $0.0001 per share (“Common Stock”), of IronNet, Inc., a Delaware corporation (“Issuer”), formerly known as LGL Systems Acquisition Corp.

John Doerr (“Doerr”), Mary Meeker (“Meeker”), and Theodore Schlein (“Schlein” and collectively with KPCB DGF II, Founders Fund, Associates, Doerr, and Meeker, the “Reporting Persons”). This Amendment No. 1 is being filed to update the aggregate percentage of the class of securities of the Issuer owned by the Reporting Persons due to dilution caused by the Issuer’s additional sales of Common Stock from time to time since the date of the filing of the Original Schedule 13D.

On October 8, 2015, KPCB DGF II and Founders Fund acquired from IronNet Cybersecurity, Inc. (“Legacy IronNet”) an aggregate 366,300 shares of Series A convertible preferred stock for a purchase price of $40.95 per share, or $15,000,000 in the aggregate.

CUSIP No. 46323Q105

Page 9 of 15 Pages

On April 27, 2018, KPCB DGF II and Founders Fund acquired from Legacy IronNet an aggregate 82,305 shares of Series B-1 convertible preferred stock for a purchase price of $72.90 per share, or $6,000,000 in the aggregate.

On February 5, 2020, KPCB DGF II and Founders Fund acquired from Legacy IronNet an aggregate 68,587 shares of Series B-2 convertible preferred stock for a purchase price of $72.90 per share, or $5,000,000 in the aggregate.

On August 26, 2021 (the “Closing Date”), Legacy IronNet, LGL Systems Acquisition Corp., a Delaware corporation (“LGL”), and LGL Systems Merger Sub Inc., a Delaware corporation (“Merger Sub”), consummated the closing of the transactions contemplated by the Agreement and Plan of Reorganization and Merger, dated March 15, 2021 and as amended August 6, 2021, by and among Legacy IronNet, LGL and Merger Sub (the “Business Combination Agreement”), following their approval at a special meeting of the stockholders of LGL held on August 26, 2021 (the “Special Meeting”).

Pursuant to the terms of the Business Combination Agreement, a business combination of Legacy IronNet and LGL was effected by the merger of Merger Sub with and into Legacy IronNet (the “Merger”), with Legacy IronNet surviving the Merger (the “Surviving Corporation”) as a wholly-owned subsidiary of LGL (the Merger, collectively with the other transactions described in the Business Combination Agreement, the “Business Combination”). Following the consummation of the Merger on the Closing Date, LGL changed its name from LGL Systems Acquisition Corp. to IronNet, Inc.

In connection with the Business Combination, KPCB DGF II and Founders Fund received 5,721,414 shares of Common Stock in exchange for an aggregate of 7,027,840 shares of Legacy IronNet. In addition, KPCB DGF II and Founders Fund may receive, as additional merger consideration, an aggregate of 80,587 shares of Common Stock if the volume weighted average share price of the Issuer’s Common Stock equals or exceeds $13.00 for ten consecutive days during the two year period following the closing of the Business Combination.

In connection with the Business Combination, KPCB DGF II and Founders Fund acquired from the Issuer an aggregate 200,000 shares of Common Stock for $10.00 per share or $2,000,000 in the aggregate.

In connection with the Business Combination, Schlein, on behalf of the Schlein Family Trust, acquired from the Issuer 100,000 shares of Common Stock for $10.00 per share or $1,000,000 in the aggregate.

In connection with the Business Combination, KPCB DGF II and Founders Fund would receive additional shares of the Issuer’s Common Stock, for no additional consideration, if the volume-weighted average closing sale price of one share of the Issuer’s Common Stock was equal to or greater than $13.00 for any ten consecutive trading days occurring after the closing date of the Business Combination. The tenth consecutive trading day was September 10, 2021. Therefore, the KPCB DGF II and Founders Fund’s right to receive the reported shares became fixed and irrevocable as of that date. KPCB DGF II and Founders Fund received an aggregate of 80,587 shares of Common Stock.

On December 7, 2021, the Issuer’s compensation committee approved the grant of 24,000 restricted stock units to Schlein as a non-employee director pursuant to the Issuer’s 2021 Equity Incentive Plan. Of the shares underlying this restricted stock unit award, one-third will vest on August 26 of each of 2022, 2023 and 2024, subject to the reporting person’s continued service with the Issuer as of the applicable date.

On July 14, 2022, pursuant to the Issuer’s non-employee director compensation policy, Schlein was awarded a number of restricted stock units equal to $180,000 divided by $2.363, the average closing price of the Issuer’s Common stock for the 10 trading days preceding the date of the annual meeting, for a total of 76,174 shares of Common Stock. The shares underlying this restricted stock award will vest July 14, 2023 or the date of the next annual meeting of stockholders, in either case subject to the reporting person’s continuous service with the Issuer through such vesting date.

The source of the funds for all purchases by KPCB DGF II and Founders Fund was from working capital. Certain purchases by KPCB DGF II and Founders Fund were made using their working capital funded partially through a line of credit with Silicon Valley Bank in the normal course of business and then paid down from the proceeds from investor capital calls.

Unless noted above, no part of the purchase price was borrowed by any Reporting Person for the purpose of acquiring any securities discussed in this Item 3.

ITEM 4.

PURPOSE OF TRANSACTION.

The Reporting Persons hold their securities of the Issuer for investment purposes. Depending on the factors discussed herein, the Reporting Persons may, from time to time, acquire additional shares of Common Stock and/or retain and/or sell all or a portion of the shares of Common Stock held by the Reporting Persons in the open market or in privately negotiated transactions, and/or may distribute the Common Stock held by the Reporting Persons to their respective members. Any actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review of numerous factors, including, among other things, the price levels of the Common Stock, general market and economic conditions, ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; the relative attractiveness of alternative business and investment opportunities, and other future developments.

Except as set forth above, the Reporting Persons have no present plans or intentions which would result in or relate to any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

(e)            As of December 31, 2023, the Reporting Persons ceased to be the beneficial owner of more than five percent of Common Stock.
