PROXY STATEMENT FOR THE 2018 ANNUAL MEETING OF STOCKHOLDERS
May 15, 2018

Information About Solicitation and Voting

        The accompanying proxy is solicited on behalf of the board of directors of Adesto Technologies Corporation ("we," "us," "our," "Adesto," or the "Company") for use at Adesto's 2018 Annual Meeting of Stockholders (the "meeting") to be held at Adesto's headquarters located at 3600 Peterson Way, Santa Clara, California on Tuesday, June 19, 2018, at 8:00 a.m. (Pacific Time), and any adjournment or postponement thereof. This Proxy Statement and the enclosed proxy card are first being mailed on or about May 18, 2018 to stockholders entitled to vote at the meeting

General Information About the Meeting

Purpose of the Meeting

        At the meeting, stockholders will act upon the proposals described in this proxy statement. In addition, following the meeting, management will respond to questions from stockholders.

Record Date; Quorum

        Only holders of record of common stock at the close of business on May 2, 2018, the record date, will be entitled to vote at the meeting. At the close of business on May 2, 2018, we had 21,454,826 shares of common stock outstanding and entitled to vote.

        The holders of a majority of the voting power of the shares of stock entitled to vote at the meeting as of the record date must be present at the meeting in order to hold the meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the meeting if you are present and vote in person at the meeting or if you have properly submitted a proxy.

Voting Rights; Required Vote

        Each holder of shares of common stock is entitled to one vote for each share of common stock held as of the close of business on May 2, 2018, the record date. You may vote all shares owned by you as of May 2, 2018, including (1) shares held directly in your name as the stockholder of record, and (2) shares held for you as the beneficial owner in street name through a broker, bank, trustee, or other nominee. On May 2, 2018 we had 21,454,826 shares of common stock issued and outstanding.

        Stockholder of Record: Shares Registered in Your Name.    If on May 2, 2018 your shares were registered directly in your name with our transfer agent, Computershare, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the meeting or vote by telephone, through the Internet, or if you request or receive paper proxy materials by mail, by filling out and returning the proxy card.

        Beneficial Owner: Shares Registered in the Name of a Broker or Nominee.    If on May 2, 2018 your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the meeting. Because you are not the stockholder of record, you may not vote your shares in person at the meeting unless you

request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the meeting.

        Each director will be elected by a plurality of the votes cast, which means that the two individuals nominated for election to our Board of Directors at the meeting receiving the highest number of "FOR" votes will be elected. You may either vote "FOR" all of the nominees, "WITHHOLD" your vote for all of the nominees or "FOR" all of the nominees except for any of the nominees that you specify. Approval of Proposal No. 2 will be obtained if the number of votes cast "FOR" such proposal at the meeting exceeds the number of votes "AGAINST" such proposal. Abstentions (shares present at the meeting and voted "abstain") are counted for purposes of determining whether a quorum is present, and have no effect on the outcome of the matters voted upon. Broker non-votes occur when shares held by a broker for a beneficial owner are not voted either because (i) the broker did not receive voting instructions from the beneficial owner, or (ii) the broker lacked discretionary authority to vote the shares. Broker non-votes are counted for purposes of determining whether a quorum is present, and have no effect on the outcome of the matters voted upon. Note that if you are a beneficial holder and do not provide specific voting instructions to your broker, the broker that holds your shares will not be authorized to vote on Proposal No. 1. Accordingly, we encourage you to provide voting instructions to your broker, whether or not you plan to attend the meeting.

Recommendations of the Board of Directors on Each of the Proposals Scheduled to be Voted on at the Meeting

        The board of directors recommends that you vote FOR each of the Class III directors named in this proxy statement (Proposal No. 1) and FOR the ratification of the appointment of BPM LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018 (Proposal No. 2).

Voting Instructions; Voting of Proxies

        If you are a stockholder of record, you may:

•

vote in person—we will provide a ballot to stockholders who attend the meeting and wish to vote in person;



•

vote via telephone or via the Internet—in order to do so, please follow the instructions shown on your proxy card; or



•

vote by mail—simply complete, sign and date the enclosed proxy card and return it before the meeting in the envelope provided.

        Votes submitted by telephone or through the Internet must be received by 11:59 p.m., Pacific Time, on June 18, 2018. Submitting your proxy (whether by telephone, through the Internet or by mail) will not affect your right to vote in person should you decide to attend the meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct it how to vote your shares. You may either vote "FOR" all of the nominees to the board of directors, or you may withhold your vote from any nominee you specify. For Proposal No. 2, you may vote "FOR", "AGAINST" or "ABSTAIN" from voting. Your vote is important. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure that your vote is counted.

        All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the meeting, your shares will be voted in accordance with the recommendations of our board or directors stated above.

Table of Contents

        If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute "broker non-votes" (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, shares that constitute broker non-votes will be counted for the purpose of establishing a quorum for the meeting.

        If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone. If you are voting by mail, please complete, sign and return each proxy card to ensure that all of your shares are voted.

Expenses of Soliciting Proxies

        The expenses of soliciting proxies will be paid by Adesto. Following the original mailing of the soliciting materials, Adesto and its agents may solicit proxies by mail, electronic mail, telephone, facsimile, by other similar means, or in person. Our directors, officers, and other employees, without additional compensation, may solicit proxies personally or in writing, by telephone, e-mail, or otherwise. Following the original mailing of the soliciting materials, Adesto will request brokers, custodians, nominees and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, Adesto, upon the request of the record holders, will reimburse such holders for their reasonable expenses.

Revocability of Proxies

        A stockholder of record who has given a proxy may revoke it at any time before it is exercised at the meeting by:

•

delivering to the Corporate Secretary of Adesto (by any means, including facsimile) a written notice stating that the proxy is revoked;



•

signing and delivering a proxy bearing a later date;



•

voting again by telephone or through the Internet; or



•

attending and voting at the meeting (although attendance at the meeting will not, by itself, revoke a proxy).

        Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.

Voting Results

        Voting results will be tabulated and certified by the inspector of elections appointed for the meeting. The final results will be tallied by the inspector of elections and filed with the Securities and Exchange Commission ("SEC") in a current report on Form 8-K within four business days of the meeting.

Implications of Being an "Emerging Growth Company"

        We are an "emerging growth company" as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, have elected to comply with certain reduced public company reporting requirements. These reduced reporting requirements include reduced disclosure about the company's executive compensation arrangements and no non-binding advisory votes on executive compensation. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE

        Adesto is strongly committed to good corporate governance practices. These practices provide an important framework within which our board of directors and management can pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Guidelines

        Our board of directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions, and other policies for the governance of the company. Our Corporate Governance Guidelines are available on the Investor Relations section of our website, which is located at http://ir.adestotech.com, by clicking on "Governance Guidelines," under "Corporate Governance." The Corporate Governance Guidelines are reviewed at least annually by our nominating and corporate governance committee, and changes are recommended to our board of directors with respect to changes as warranted.

Board Leadership Structure

        Our Corporate Governance Guidelines provide that our board of directors shall be free to choose its chairman in any way that it considers in the best interests of our company, and that the nominating and corporate governance committee shall periodically consider the leadership structure of our board of directors and make such recommendations related thereto to the board of directors with respect thereto as the nominating and corporate governance committee deems appropriate. Our Corporate Governance Guidelines also provide that, when the positions of chairman and chief executive officer are held by the same person, the independent directors shall designate a "lead independent director." The responsibilities of the chairman or the lead independent director include: scheduling and setting the agenda for each meeting of our board directors; presiding at executive sessions; being available, under appropriate circumstances, for consultation and direct communication with stockholders; and facilitating communication between the independent directors and management.

        Currently, the roles of chief executive officer and chairman are separate. Nelson Chan, one of our independent directors, was appointed as Chairman of the Board of Directors in June 2017. Our board of directors believes that having an independent director serve as the Chairman of the Board is the appropriate leadership structure for our company at this time because it allows our President and Chief Executive Officer, Narbeh Derhacobian, to focus on executing our company's strategic plan and managing our company's operations and performance, while allowing the Chairman of the Board to focus on the effectiveness of the Board and independent oversight of our senior management team. Our Chairman of the Board and other independent directors bring experience, oversight and expertise from outside of our company, while our President and Chief Executive Officer brings company-specific experience and expertise. Our board of directors believes that this governance structure provides strong leadership, creates clear accountability, and enhances our ability to communicate our message and strategy clearly and consistently to stockholders. Our board of directors believes that its independence and oversight of management is maintained effectively through this leadership structure, the composition of the board of directors and sound corporate governance policies and practices.

Our Board of Directors' Role in Risk Oversight

        Our board of directors, as a whole, has responsibility for risk oversight, although the committees of our board of directors oversee and review risk areas which are particularly relevant to them. In its risk oversight role, the board of directors has the responsibility to assess that the risk management processes designed and implemented by management are adequate and functioning as designed. These areas of focus include, but are not limited to, operational, financial, legal, economics and competitive risks.

Table of Contents

        The committees of the board of directors assist our board in fulfilling its oversight role in certain areas of risk management. The audit committee oversees our financial and reporting processes and the audit of the financial statements of our company and provides assistance to the board of directors with respect to the oversight and integrity of our financial statements, our compliance with legal and regulatory matters, the independent auditor's qualification and independence, and the performance of our independent auditor. The nominating and corporate governance committee oversees governance-related risks, such as compliance with director independence and conflicts of interests requirements. The compensation committee considers the risks that our compensation policies and practices may have in attracting, retaining, and motivating employees.

Independence of Directors

        Our board of directors determines the independence of our directors by applying the independence principles and standards established by the NASDAQ Stock Market ("NASDAQ"). These provide that a director is independent only if the board of directors affirmatively determines that the director does not have a relationship with the company which, in the opinion of the board of directors, would interfere with the exercise of his independent judgment in carrying out the responsibilities of a director. They also specify various relationships that preclude a determination of director independence. Material relationships may include employment, commercial, accounting, family and other business, professional and personal relationships.

        Applying these standards, the board of directors annually reviews the independence of the company's directors, taking into account all relevant facts and circumstances. In its most recent review, the board of directors considered, among other things, the relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

        Based upon this review, our board of directors has determined that the following director nominee and members of our board of directors are currently independent as determined under the rules of the NASDAQ:

        All members of our audit committee, compensation committee, and nominating and corporate governance committee must be independent directors as defined by our Corporate Governance Guidelines. Members of the audit committee must also satisfy a separate SEC independence requirement, which provides that they may not accept directly or indirectly any consulting, advisory or other compensatory fee from Adesto or any of its subsidiaries other than their directors' compensation. Our board of directors has determined that all members of our audit committee, compensation committee and nominating and corporate governance committee are independent and all members of our audit committee satisfy the relevant additional SEC independence requirements for the members of such committee.

Committees of Our Board of Directors

        Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Copies of the charters for each committee are available, without charge, upon request in writing to Adesto Technologies Corporation, 3600 Peterson Way, Santa Clara, California 95054, Attn: Corporate Secretary or by clicking on "Corporate Governance" in the investor

None of our current executive officers has served as a member of the board of directors, or as a member of the compensation or similar committee, of any entity that has one or more executive officers who served on our board of directors or compensation committee during the year ended December 31, 2017.

Board and Committee Meetings and Attendance

        The board of directors is responsible for the management and direction of the Company and for establishing broad corporate policies. The board of directors meets periodically during the Company's fiscal year to review significant developments affecting the Company and to act on matters requiring board of directors approval. The board of directors held seven meetings during 2017, the audit committee held four meetings, the compensation committee held two meetings, and the nominating and corporate governance committee did not hold a meeting. During 2017, only one director, Mr. Palatnik, attended fewer than 75% of the aggregate of all meetings of the board of directors and the aggregate of all meetings of committees on which such member served, that were held during the period in which such director served during 2017.

Board Attendance at Annual Stockholders' Meeting

        We invite and encourage each member of our board of directors to attend our annual meetings of stockholders. We do not have a formal policy regarding attendance of annual meetings by the members of our board of directors. At our 2017 annual meeting of stockholders, we had three directors in attendance.

NOMINATIONS PROCESS AND DIRECTOR QUALIFICATIONS

Nomination to the Board of Directors

        Candidates for nomination to our board of directors are selected by our board of directors based on the recommendation of the nominating and corporate governance committee in accordance with the committee's charter, our certificate of incorporation and bylaws, our Corporate Governance Guidelines, and the criteria adopted by the board of directors regarding director candidate qualifications. In recommending candidates for nomination, the nominating and corporate governance committee considers candidates recommended by directors, officers, employees, stockholders and others, using the same criteria to evaluate all candidates. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected candidates as appropriate and, in addition, the committee may engage consultants or third-party search firms to assist in identifying and evaluating potential nominees.

        Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our board of directors is set forth below under "Stockholder Proposals to Be Presented at Next Annual Meeting."

Director Qualifications

        With the goal of developing a diverse, experienced and highly-qualified board of directors, the nominating and corporate governance committee is responsible for developing and recommending to the board of directors the desired qualifications, expertise and characteristics of members of our board of directors, including the specific minimum qualifications that the committee believes must be met by a committee-recommended nominee for membership on the board of directors and any specific qualities or skills that the committee believes are necessary for one or more of the members of the board of directors to possess.

        Since the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of the board of directors from time to time, our board of directors has not adopted a specific set of minimum qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal, regulatory and NASDAQ listing requirements and the provisions of our certificate of incorporation, bylaws, Corporate Governance Guidelines, and charters of the board committees. In addition, neither the board of directors nor the nominating and corporate governance committee has a formal policy with regard to the consideration of diversity in identifying nominees. When considering nominees, the nominating and corporate governance committee may take into consideration many factors including, among other things, a candidate's independence, integrity, skills, financial and other expertise, breadth of experience, knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of the board of directors in the context of its existing composition. Through the nomination process, the nominating and corporate governance committee seeks to promote board membership that reflects a diversity of business experience, expertise, viewpoints, personal backgrounds and other characteristics that are expected to contribute to the board of directors' overall effectiveness. The brief biographical description of each director set forth in Proposal No. 1 below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our board of directors at this time.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

        Our board of directors currently consists of five directors and is divided into three classes with each class serving for three years, and with the terms of office of the respective classes expiring in successive years. Directors in Class III will stand for election at this meeting. The terms of office of directors in Class I and Class II do not expire until the annual meetings of stockholders held in 2019 and 2020, respectively. At the recommendation of our nominating and corporate governance committee, our board of directors proposes that each of the Class III nominees named below, each of whom is currently serving as a director in Class III, be elected as a Class III director for a three-year term expiring at the 2021 Annual Meeting of Stockholders and until such director's successor is duly elected and qualified or until such director's earlier resignation or removal.

        Shares represented by proxies will be voted "FOR" the election of each of the two nominees named below, unless the proxy is marked to withhold authority so to vote. If any nominee for any reason is unable to serve or for good cause will not serve, the proxies may be voted for such substitute nominee as the proxy holder might determine. Each nominee has consented to being named in this proxy statement and to serve if elected.

2017 Incentive Bonuses

        2017 Executive Officer Incentive Bonus Plan.    In March 2017, our compensation committee approved a bonus plan for 2017 ("Bonus Plan") for our named executive officers, with target bonus amounts thereunder of 35% of 2017 annual base salary for Messrs. Derhacobian and Shelton and 25% for Mr. Intrater (each, the "on-target bonus payment"). Under the Bonus Plan, following completion of 2017, participants were eligible to receive a bonus equal to the applicable on-target bonus payment multiplied by the Bonus Multiplier (as defined below), in each case based on attainment of performance objectives derived from our financial plan for 2017 and the non-financial management and business objectives ("MBOs") established for each participant by our compensation committee. The "Bonus Mulitplier" (which may be less than or more than 100%) is calculated as follows:

        ((Financial objective weighting × (Financial objective performance percentage)) + MBO performance percentage

Table of Contents

        Performance objectives included achievement of financial goals and MBOs, which were weighted at 70% for Messrs. Derhacobian and Shelton and 60% for Mr. Intrater, respectively, with the balance weighting percentage allocated to MBOs (which in the aggregate may not exceed 100% of such percentage). The financial objectives for all are expressed in terms of revenue, gross margin, and adjusted EBITDA (as defined in our earnings release) and are measured independently and weighted at target level at 35% (53.8% maximum), 35% (53.8% maximum) and 30% (60% maximum), respectively. Specific MBOs for each participant were established by our compensation committee to align with our operational and strategic objectives and participant's area of responsibility. Following the end of 2017, our compensation committee reviewed the achievement of Mr. Derhacobian's, Mr. Shelton's, and Mr. Intrater's objectives and approved the cash incentive amount earned by them, each as described in the "Non-Equity Incentive Plan Compensation" column of Summary Compensation Table. The table below sets forth the bonus calculation for the Bonus Multplier for each named executive officer under the Bonus Plan:

Each of these restricted stock units vests quarterly over four years, beginning on July 1 2017. Also, effective April 1, 2017, our compensation committee approved grants of PRSUs under our 2015 Equity Incentive Plan to each of our named executive officers for the following target number of shares of common stock ("target shares"): 45,000 shares for Mr. Derhacobian; 37,500 shares for Mr. Shelton; and 9,728 shares for Mr. Intrater. The target shares shall become earned under the PRSUs only if (x) our financial performance meets or exceeds all three of the goals for our revenue, gross profit and EBITDA contained in our financial plan for 2017 and (y) the average closing price per share of common stock for the 30 consecutive trading days prior to and including March 30, 2018 meets or exceeds a pre-established price per share, as adjusted for any cumulative appreciation of the Nasdaq Composite Index from March 31, 2017 to March 30, 2018. If any target shares become earned ("earned shares") as a result of achievement of all of the performance metrics described above, then 20% of the earned shares shall vest on the date that our compensation committee determines the actual achievement of the performance metrics and the remainder will vest in equal quarterly installments on June 30, 2018 and at the end of each of the next seven quarters thereafter until all of the earned shares have completed vested.

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

        From January 1, 2017 to the present, there have been no transactions, and there are currently no proposed transactions, in which the amount involved exceeds $120,000 to which we or any of our subsidiaries was (or is to be) a party and in which any director, director nominee, executive officer, holder of more than 5% of our capital stock, or any immediate family member of or person sharing the household with any of these individuals, had (or will have) a direct or indirect material interest, except for payments set forth under "Proposal No. 1" and "Executive Compensation" above.

Policies and Procedures for Related-Party Transactions

        We have adopted a written related-person transactions policy that provides that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock, and any members of the immediate family of the foregoing persons, are not permitted to enter into a material related-person transaction with us without the review and approval of our audit committee, or a committee composed solely of independent directors in the event it is inappropriate for our audit committee to review such transaction due to a conflict of interest. The policy provides that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates, in which the amount involved exceeds $120,000 will be presented to our audit committee for review, consideration and approval. In approving or rejecting any such proposal, we expect that our audit committee will consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person's interest in the transaction.

"Householding"—Stockholders Sharing the Same Last Name and Address

        The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called "householding." Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our annual report and proxy materials unless the affected stockholder has provided contrary instructions. This procedure reduces printing costs and postage fees, and helps protect the environment as well.

Table of Contents

        This year, a number of brokers with account holders who are Adesto stockholders will be "householding" our annual report and proxy materials. A single set of annual report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting Computershare, either by calling toll-free (877) 373-6374, or by writing to Computershare, Householding Department, P.O. Box 43078, Providence, RI, 02940-3078.

        Upon written or oral request, we will promptly deliver a separate copy of the annual report and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the annual report and other proxy materials, you may write or email our Investor Relations department at 3600 Peterson Way, Santa Clara, California 95054, Attn: Investor Relations, email address sheltonir@sheltongroup.com.

        Any stockholders who share the same address and currently receive multiple copies of our annual report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about householding or our Investor Relations department at the address or email address listed above.

As to any business that may arise and properly come before the meeting, however, it is intended that proxies, in the form enclosed, will be voted in respect thereof in accordance with the judgment of the persons voting such proxies.
