OUR COMPANY

This summary highlights information contained in the documents incorporated herein by reference. Before making an investment decision, you should read the entire Prospectus, and our other filings with the Securities and Exchange Commission, or the SEC, including those filings incorporated herein by reference, carefully, including the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

We were originally formed on October 8, 2014 as a blank check company under the name Jensyn Acquisition Corp. for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination, with one or more businesses or entities. On June 20, 2019, we completed a business combination (the “Business Combination”) pursuant to which we acquired Peck Electric Co. (“Peck Electric”). Following the Business Combination, we changed our name to The Peck Company Holdings, Inc.

We are one of the largest commercial solar engineering, procurement and construction (“EPC”) companies in the country and are expanding across the Northeastern United States. The Company is a second-generation family business founded under the name Peck Electric Co. in 1972 as a traditional electrical contractor. The Company’s core values are to align people, purpose, and profitability, and since taking leadership in 1994, Jeffrey Peck, the Company’s Chief Executive Officer, has applied such core values to expand into the solar industry. Today, the Company is guided by the mission to facilitate the reduction of carbon emissions through the expansion of clean, renewable energy and we believe that leveraging such core values to deploy resources toward profitable business is the only sustainable strategy to achieve these objectives.

The world recognizes the need to transition to a reliable, renewable energy grid in the next 50 years. Vermont and Hawaii are leading the way in the U.S. with renewable energy goals of 75% by 2030 and 100% by 2045, respectively. California committed to 100% carbon-free energy by 2045. 29 other states also have renewable energy goals regardless of current Federal solar policy. The Company intends to use near-term incentives to take advantage of long-term, sustainable energy transformation with a commitment to the environment and to its shareholders. Our triple bottom line, which is geared towards people, environment, and profit, has always been our guide since we began installing renewable energy and we intend that it remain our guide over the next 50 years as we construct our energy future.

TABLE OF CONTENTS

We primarily provide EPC services to solar energy customers for projects ranging in size from several kilowatts for residential loads to multi-megawatt systems for large commercial and utility projects. To date, we have installed over 165 megawatts of solar systems since inception and are focused on profitable growth opportunities. We believe that we are well-positioned for what we believe to be the coming transformation to an all renewable energy economy. As a result of the completion of the Business Combination, we have now opened our family company to the public market as part of our strategic growth plan. We are expanding across the Northeastern United States to serve the fast-growing demand for clean renewable energy. We are open to partnering with others to accelerate our growth process, and we are expanding our portfolio of company-owned solar arrays to establish recurring revenue streams for many years to come. We have established a leading presence in the market after five decades of successfully serving our customers, and we are now ready for new opportunities and the next five decades of success.

Recently our growth has been derived by increasing our solar customer base starting in 2013 and by continuing to serve the needs of existing electrical and data customers. We have installed some of the largest commercial and utility-scale solar arrays in the state of Vermont. Our union crews are expert constructors, and union access to an additional workforce makes us ready for rapid expansion to other states while maintaining control of operating costs.

We also make investments in solar development projects and currently own approximately three megawatts of operating solar arrays operating under long-term power purchase agreements. These long-term recurring revenue streams, combined with our in-house development and construction capabilities, make this asset class a strategic long-term investment opportunity for us.

We are a member of Renewable Energy Vermont, an organization that advocates for clean, practical and renewable solar energy.

Approximately 70% of our revenue is derived from solar business, approximately 30% of revenue is derived from electrical and data business and less than 1% of revenue is currently derived from recurring revenue of Company-owned solar arrays. We have a three-pronged growth strategy that includes (1) organic expansion across the Northeastern United States, (2) conducting accretive merger and acquisition transactions to expand geographically, and (3) investing into company-owned solar assets.

•	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 under the Securities Act, if available, rather than under this Prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

In connection with the sale of the securities covered hereby, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities. We have agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because the Selling Stockholders may be deemed to be an “underwriter” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act, including Rule 172 thereunder. In

addition, any securities covered by this Prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this Prospectus. Each Selling Stockholder has advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale securities by the Selling Stockholder.

We agreed to keep this Prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for us to be in compliance with the current public information requirement under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Stockholders or any other person. We will make copies of this Prospectus available to the Selling Stockholders and have informed the Selling Stockholders of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
