Business Overview

Yield10 Bioscience, Inc. ("Yield10" or the "Company") is an agricultural bioscience company focused on commercializing sustainable products using the oilseed Camelina sativa ("Camelina") as a platform crop. Yield10 is headquartered in Woburn, Massachusetts and has a Canadian subsidiary, Yield10 Oilseeds Inc., located in Saskatoon, Saskatchewan, Canada.

We are pursuing Camelina seed oil products for two market opportunities and value chains. The first product is seed oil produced by Camelina, which has been genetically engineered to enable production of high levels of the omega-3 fatty acids eicosapentanoic acid (EPA) and docosahexanoic acid (DHA). Our development is driven by the growing demand for new sources of omega-3 ingredients and the production constraints and supply volatility of the traditional raw material source fish oil. This growing omega-3 supply gap offers a market opportunity with the potential for revenue and margin growth at acreage levels operationally accessible to Yield10. When commercially available, the Company's omega-3 products will address an unmet need for a reliable, scalable supply of EPA and DHA omega-3 ingredients for aquaculture and pet/animal feed. Multiple opportunities exist for further product development to address higher value markets for omega-3 oils in nutraceuticals and pharmaceuticals. Earlier this year we received regulatory approval from USDA-APHIS for two engineered Camelina lines, the first produces our EPA Omega-3 product and the second produces our EPA+DHA Omega-3 product.

The second product is Camelina seed oil for use as a low-carbon intensity feedstock oil for biofuels, including biodiesel, renewable diesel (“RD”) and sustainable aviation fuel (“SAF”). Markets for biofuels are driven by government policies, have the potential to be very large, and will require the production of tens of millions of acres of new oilseed cover crops like Camelina that do not compete for land with food production.

We selected Camelina, an annual oilseed plant in the mustard family, as our platform crop based on its unique attributes, including its excellent agronomic traits, such as low water and fertilizer input, drought resistance and its short growing cycle. Based on Camelina's flexible agronomic profile, we believe growers have the option of using Camelina as a winter cover crop, as a relay crop with soybean in the U.S. Midwest, and as a spring rotation crop within the U.S. and regions of Canada. Meeting the growing demand for biofuel feedstocks in North America will require tens of millions of acres of new non-food oilseed production. Given today's crop production practices, the best way to access this acreage scale is through double cropping using short season winter oilseeds as cash cover crops integrated into crop rotations in a second growing season with the major food crops corn and soybean. Winter cover crops reduce soil erosion and nutrient runoff, promote soil health and trap subsoil moisture. Camelina is in the same plant family as canola and naturally produces a relatively abundant harvest of oil-containing protein-rich seeds. Camelina has no close plant relatives in North America and as a new non-food crop it is readily segregated from commodity crops making it advantaged for producing novel seed products. This dramatically simplifies the regulatory path for engineered products in North America. Planting, harvesting, storage and transportation of Camelina does not require growers to make capital investments in new equipment. The grain can be processed in soft seed (e.g. canola) crushing facilities, using either cold press or solvent extraction and the residual protein meal can be used in certain animal feed rations in the U.S. and Canada once regulatory approval has been obtained. To unlock this potential and make Camelina an attractive option for farmers, we are developing and plan to commercialize advanced varieties with elite weed control herbicide tolerance traits, improved agronomic performance, and increased crop value.

We learned through our interactions with growers that developing elite weed control technology for Camelina to enable seamless integration into current crop rotations is a critical factor in achieving large-scale adoption of Camelina as a new crop. As a result, we prioritized the development of herbicide tolerant Camelina over the past four years. We have successfully developed commercial-quality Camelina varieties containing an herbicide tolerant (“HT”) trait for glufosinate tolerance alone or as a stacked herbicide tolerant (“stacked HT”) trait for glufosinate tolerance in combination with tolerance to Group 2 herbicides, specifically including tolerance to both imidazolinones and sulfonylureas. The prevalence and persistence of Group 2 soil residues in some production regions limit the amount of land available for planting conventional Camelina. In November of 2023, our HT and stacked HT technologies received regulatory approval from USDA-APHIS indicating that the agency does not consider our Camelina varieties with these traits to be regulated in the United States. In early 2024, over 50 acres of our spring E3902 HT Camelina was harvested

from a contra season seed scale-up conducted in Chile. This accomplishment from first field trials of HT Camelina in the spring of 2022 to regulatory approval in Q4 of 2023 and seed bulk up to tonnage scale in Q1 of 2024 reflects Yield10's development strengths. We believe this outcome together with the more recent approvals for our Omega-3 Camelina reflects the favorable regulatory path for engineered Camelina in the U.S. and bodes well for the accelerated development of this crop using Yield10s advanced technology, gene traits and capabilities. Subject to the availability of sufficient financial resources, we plan to continue our development work with spring E3902 stack HT Camelina and winter stack HT Camelina during 2024, in order to continue our assessment of the efficacy of the traits in-field agronomics, seed yields and oil content.

We plan to bring both Omega-3 Camelina products forward in development with 2026 being the target for the first commercial-scale production of the EPA8 oil. Herbicide tolerance is critical in Camelina for on-farm performance. We are currently breeding HT traits into both current Omega-3 Camelina varieties to create second generation varieties for large acreage production. As a world leader in Camelina seed genetics and advanced trait technology development, Yield10 shares a common goal with the aquaculture industry including feed and salmon producers to establish the commercial production of thousands of tons of Camelina omega-3 oil as a new scalable, cost effective, and sustainable supplement to fish oil. We believe Camelina omega-3 oil production at scale (50,000 tons per year, based on approximately 200,000 acres) can reduce supply and price volatility in aquafeed and farmed salmon production leading to a potential increase the growth rate of the industry.

March 2024 Warrant Exchange

On March 22, 2024, we entered into the Exchange Agreement with certain existing institutional investors, pursuant to which the institutional investors agreed to exercise (the “Exercise”) (i) a portion of the warrants issued to such institutional investors in May 2023, which were exercisable for 671,140 shares of the Company’s common stock, and had an exercise price of $2.98 per share (the “May 2023 Warrants”) and (ii) a portion of the warrants issued to such institutional investors in August 2023, which were exercisable for 2,520,000 shares of common stock and had an exercise price of $0.65 per share (the “August 2023 Warrants” and together with the May 2023 Warrants, the “Existing Warrants”). In consideration for the immediate exercise of 3,191,140 of the Existing Warrants for cash, the Company agreed to reduce the exercise price of the Existing Warrants held by such institutional investors to $0.43 per share, which was equal to the most recent closing price of the Company’s common stock on Nasdaq prior to the execution of the Exchange Agreement. In addition, in consideration for the Exercise, the institutional investors received the Warrants to purchase up to an aggregate of 6,382,280 shares of common stock, equal to 200% of the shares of common stock issued in connection with the Exercise, with an exercise price of $0.43 per share in a private placement pursuant to Section 4(a)(2) of the Securities Act.

Due to the number of shares of common stock that may be issued upon the exercise of the Warrants, the Company is required to obtain stockholder approval of the issuance of up to 6,382,280 shares of common stock in accordance with Nasdaq Listing Rule 5635(d) (the "Stockholder Approval"). Nasdaq Listing Rule 5635(d) requires stockholder approval prior to the issuance of securities in connection with a transaction other than a public offering involving the sale, issuance or potential issuance of common stock (or securities convertible into or exercisable for common stock) in an amount equal to 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance at a price less than the “Minimum Price.” The Minimum Price is defined as the lower of (i) the closing price of the common stock immediately preceding the signing of the sale agreement or (ii) the average closing price of the common stock for the five trading days immediately preceding the signing of the sale agreement.

The Warrants will not be exercisable until the Stockholder Approval is obtained. The Company is seeking the Stockholder Approval at its 2024 Annual Meeting of Stockholders on June 7, 2024. Once the Stockholder Approval is obtained on or after June 7, 2024 the Warrants will be exercisable for five years from such initial exercisability date. The private placement in which we issued the Warrants was exempt from registration pursuant to Section 4(a)(2) and/or Rule 506 of the Securities Act. The Exchange closed on March 26, 2024. The gross proceeds were $1.4 million before deducting the warrant solicitation agent fees and other expenses.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described below and in the section captioned “Risk Factors” contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the Securities and Exchange Commission (“SEC”) on April 1, 2024 and other filings we make with the SEC from time to time, which are incorporated by reference herein in their entirety, together with other information in this prospectus and the information incorporated by reference herein. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could suffer materially. In such event, the trading price of our common stock could decline, and you might lose all or part of your investment.

There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq.

We cannot assure you that we will be able to comply with the standards that we are required to meet in order to maintain a listing of our common stock on Nasdaq. Nasdaq listing rules require us to maintain certain closing bid price, stockholders’ equity and other financial metric criteria in order for our common stock to continue trading on Nasdaq. For example, Nasdaq Listing Rule 5550(a)(4) requires companies to maintain a minimum of 500,000 publicly held shares. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share, and Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days.

On September 25, 2023, we received a deficiency letter from the Listing Qualifications Department (the “Staff”) of Nasdaq notifying the Company that for the previous 30 consecutive business days, the bid price for the Company’s common stock had closed below the minimum $1.00 per share requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided an initial period of 180 calendar days, or until March 25, 2024, to regain compliance with the Minimum Bid Price Rule. The Company was unable to regain compliance with the Minimum Bid Price Rule prior to the expiration of the 180 calendar day period. The Company participated in a hearing before the Nasdaq Hearings Panel (the "Panel") on February 6, 2024. On February 13, 2024, the Company was notified by the Panel that it had been granted an additional extension to remain listed on The Nasdaq Capital Market until May 13, 2024, subject to certain conditions. These conditions include that the Company provide a written update on the status of its plans to obtain financing and strengthen its balance sheet by March 15, 2024, as well as provide prompt notification of any significant events during the period of extension that may affect the Company's compliance with Nasdaq requirements. The Company provided this update to Nasdaq on March 14, 2024.

On March 26, 2024, the Company received written notice from the Staff stating that the Company is not eligible for a second 180 day compliance period for the Minimum Bid Price Rule deficiency because the Company does not comply with the $5,000,000 minimum stockholders’ equity initial listing requirement for The Nasdaq Capital Market. The Notice required the Company to present its views with respect to this deficiency to the Panel in writing no later than April 2, 2024. The Company provided a written response on April 2, 2024, indicating that a special meeting of stockholders has been scheduled for April 26, 2024 to approve a reverse stock split, in order to increase the price of its common stock to a level that will satisfy the Minimum Bid Price Rule, among other measures. On April 5, 2024, the Company received an additional notice from the Staff indicating that it has until May 13, 2024 to demonstrate compliance with all applicable requirements for continued listing on Nasdaq.

There continues to be no immediate effect on the listing of the Company’s common stock, which continues to trade on Nasdaq under the symbol “YTEN.” The Company is working diligently to satisfy, and intends to regain compliance with, the applicable requirements for continued listing on Nasdaq. However, there can be no assurance that the Company will be able to regain compliance with these requirements or that Nasdaq will grant the Company a further extension of time to achieve compliance with these requirements.

SELLING SECURITY HOLDERS

The shares of common stock being offered by the selling security holders are those issued upon the exercise of the Warrants. For additional information regarding the issuance of these securities, see “Prospectus Summary - March 2024 Warrant Exchange”. We are registering the shares of common stock in order to permit the selling security holders to offer the shares for resale from time to time. The Warrants have an exercise price of $0.43 and will be exercisable on or after June 7, 2024, once the Stockholder Approval is obtained] and will expire five years from such initial exercisability date. Other than as described below, the selling security holders have not had any material relationship with us within the past three years.

The selling security holders might not sell any or all of the shares covered by this prospectus or may sell or dispose of some or all of the shares other than pursuant to this prospectus. Because the selling security holders may not sell or otherwise dispose of some or all of the shares covered by this prospectus and because there are currently no agreements, arrangements or understandings with respect to the sale or other disposition of any of the shares, we cannot estimate the number of the shares that will be held by the selling security holders after completion of the offering.

The table below lists the selling security holders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of the shares of common stock held by each of the selling security holders. The table is prepared based on information supplied to us by the selling security holders. The second column lists the number of shares of common stock beneficially owned by the selling security holders, based on their respective ownership of shares as of April 19, 2024. The fourth column lists the shares of common stock being offered by this prospectus by the selling security holders. The fifth column assumes the sale of all of the shares offered by the selling security holders pursuant to this prospectus. The percentages in the table reflect the shares beneficially owned by the selling security holders as a percentage of the

total number of shares of common stock outstanding as of April 19, 2024. As of such date, 15,420,951 shares of common stock were outstanding.

PLAN OF DISTRIBUTION

Each Selling Stockholder of the shares of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on Nasdaq or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

•ordinary brokerage transactions and transactions in which the broker‑dealer solicits purchasers;

•block trades in which the broker‑dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•purchases by a broker‑dealer as principal and resale by the broker‑dealer for its account;

•an exchange distribution in accordance with the rules of the applicable exchange;

•privately negotiated transactions;

•settlement of short sales;

•in transactions through broker‑dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

•through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•a combination of any such methods of sale; or

•any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration 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 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, 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 the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

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 the Company to be in compliance with the current public information 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 them 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).

DESCRIPTION OF OUR CAPITAL STOCK

General

The following summary of our capital stock is based on certain provisions of our amended and restated certificate of incorporation, as amended, and amended and restated by-laws and on the applicable provisions of the Delaware General Corporation Law (the “DGCL”). This summary does not purport to be complete and is qualified in its entirety by reference to the applicable provisions in our amended and restated certificate of incorporation, as amended, and amended and restated by-laws and the DGCL. For a complete description you should refer to our amended and restated certificate of incorporation, as amended, and our amended and restated by-laws, copies of which have been incorporated by reference herein, and to the applicable provisions of the DGCL

Our authorized capital stock consists of 65,000,000 shares, with a par value of $0.01 per share, of which:

•60,000,000 shares are designated as common stock; and

•5,000,000 shares are designated as preferred stock. Previously issued shares of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock have been fully converted to common stock and are no longer outstanding.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of our stockholders and do not have cumulative voting rights. Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of outstanding shares of common stock are entitled to receive ratably any dividends declared by our board of directors out of assets legally available. Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding shares of preferred stock. Holders of common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock.

Preferred Stock

Our amended and restated certificate of incorporation, as amended, provides for a class of its authorized stock known as preferred stock, consisting of 5,000,000 shares, $0.01 par value per share, issuable from time to time in one or more series. Currently, there are no shares of preferred stock issued and outstanding. Our board of directors may designate the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, sinking fund terms and the number of shares constituting any series or the designation of any series.

Warrants

As of April 19, 2024, we had warrants outstanding to purchase 4,680,598 shares of our common stock.

Anti-Takeover Provisions

Certain provisions of the DGCL and our amended and restated certificate of incorporation, as amended, and amended and restated by-laws may have the effect of delaying, deferring or discouraging another party from acquiring control of our company. These provisions, which are summarized below, may discourage certain types of coercive takeover practices and inadequate takeover bids and encourage anyone seeking to acquire control of our company to first negotiate with our board of directors. These provisions might also have the effect of preventing changes in our management and could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests. However, we believe that the advantages gained by protecting our ability to negotiate with any unsolicited and potentially unfriendly acquirer outweigh the disadvantages of discouraging such proposals, because, among other reasons, the negotiation of such proposals could result in improving their terms.

Amended and Restated Certificate of Incorporation and Bylaw Provisions

Our amended and restated certificate of incorporation, as amended, and amended and restated by-laws include a number of provisions that may have the effect of delaying, deferring or discouraging another party from acquiring control of our company or preventing changes in our management, including the following:

•Issuance of Undesignated Preferred Stock. Our board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of undesignated preferred stock with rights, preferences and privileges designated from time to time by our board of directors without further action by stockholders. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences and sinking fund terms, any or all of which may be greater than the rights of common stock.

•Size of the Board of Directors and Filling Vacancies. The number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our entire board of directors. Any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of the board of directors, may only be filled by the affirmative vote of a majority of our directors then in office, even if less than a quorum.

•Classified Board. Our board of directors is divided into three classes of directors, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms.

•No Cumulative Voting. Our amended and restated certificate of incorporation, as amended, and amended and restated by-laws do not permit cumulative voting in the election of directors. Cumulative voting allows a stockholder to vote a portion, or all of its shares for one or more candidates. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat.

•Removal of Directors. Directors can only be removed by our stockholders for cause and removal of a director will require a 75% stockholder vote.

•No Written Consent of Stockholders. All stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting. Stockholders may not take action by written consent in lieu of a meeting. The inability of stockholders to take action by written consent means that a stockholder would need to wait until the next annual or special meeting to bring business before the stockholders for a vote.

•Special Meetings of Stockholders. Special meetings of our stockholders may be called only by our board of directors acting pursuant to a resolution approved by the affirmative vote of a majority of the directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of our stockholders.

•Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our amended and restated by-laws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. These procedures provide that notice must be given in writing not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. These procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of us.

•Amendment to Amended and Restated Certificate of Incorporation and By-laws. Any amendment, repeal or modification of certain provisions of our amended and restated certificate of incorporation, as amended, or amended and restated by-laws requires a 75% stockholder vote. Provisions requiring such supermajority vote include, among other things, any amendment, repeal or modification of the provisions relating to the classification of our board of directors, the requirement that stockholder actions be effected at a duly called annual or special meeting of our stockholders and the designated parties entitled to call a special meeting of our stockholders.

Section 203 of the DGCL

We are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless it satisfies one of the following conditions:

•the transaction is approved by the board of directors prior to the time that the interested stockholder became an interested stockholder;

•upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

In general, Section 203 defines “business combination” to include the following:

•at or subsequent to such time that the stockholder became an interested stockholder, the business combination was approved by the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

•any merger or consolidation involving the corporation and the interested stockholder;

•any sale, lease, exchange, mortgage, pledge, transfer or other disposition of the assets of the corporation with an aggregate market value of 10% or more of either the aggregate market value of all assets of the corporation on a consolidated basis or the aggregate market value of all of the outstanding stock of the corporation involving the interested stockholder;

•subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the stockholder’s affiliates and associates (as defined in Section 203), beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Treatment of Options Upon Change of Control

In general, under the terms of our equity incentive plans and our executive employment agreements, in the event of certain change in control transactions, if the successor corporation does not assume our outstanding options or issue replacement awards, or if an option holder’s employment is involuntarily terminated in connection with such change in control, the vesting of the options outstanding under such plans will accelerate.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC. The transfer agent’s telephone number is 1-800-937-5449.

Stock Exchange Listing

Our common stock is listed on Nasdaq under the symbol “YTEN”.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that:

Paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser: each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 (§ 230.424 of this chapter);

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this Registration Statement on Form S-1 to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Woburn, Massachusetts, on April 25, 2024.
