Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Reverse Stock Split

On May 2, 2024, the Company filed a Certificate of Amendment (the Reverse Stock Split Amendment) to the Company’s Restated Certificate of Incorporation with the Secretary of State of Delaware to effect a 1-for-18 Reverse Stock Split of the Company's common stock (the Reverse Stock Split), which became effective on May 9, 2024. The Reverse Stock Split Amendment did not reduce the number of authorized shares of common stock, which remains at 100,000,000, and did not change the par value of the common stock, which remains at $0.0001 per share. As a result of the Reverse Stock Split, every eighteen shares of the common stock were combined into one issued and outstanding share of common stock and no fractional shares were issued. Instead, to any holder who would have otherwise been entitled to receive a fractional share of common stock, the Company issued such holder an additional fractional share, such that, when combined with the fractional share otherwise issuable as a result of the Reverse Stock Split, equaled a whole share of common stock.

All share and per share information shown herein has been retroactively adjusted to reflect the effect of the Reverse Stock Split Amendment for all periods presented.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP), and include the accounts of the Company and its wholly owned subsidiaries after the elimination of all significant intercompany accounts and transactions. Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (ASC) and as amended by the ASUs of the Financial Accounting Standards Board (FASB).

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s condensed consolidated balance sheet as of June 30, 2024, the condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2024 and 2023, condensed consolidated statements of stockholders’ (deficit) equity for the three and six months ended June 30, 2024 and 2023 and the condensed consolidated statements of cash flows for the six months ended June 30, 2024 and 2023.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the accompanying notes for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 29, 2024 (the Annual Report). The condensed consolidated balance sheet data as of December 31, 2023 presented for comparative purposes was derived from the Company’s audited consolidated financial statements but does not include all disclosures required by U.S. GAAP and Article 8 of Regulation S-X. The results for the three and six months ended June 30, 2024 and 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period.

The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2023 included in the Annual Report. Since the date of the audited consolidated financial statements for the year ended December 31, 2023 included in the Annual Report, there have been no changes to its significant accounting policies except as noted below.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods presented. Key estimates in the consolidated financial statements include the Company’s ability to continue as a going concern, revenue recognition, impairment assessment for goodwill and intangible assets, allowance for credit losses, estimated useful lives of property and equipment, valuation of inventory, accrued expenses, valuation of deferred income tax assets, valuation of derivative liabilities, valuation of preferred stock and warrants, share-based compensation, and accrued warranty are subject to significant estimation. Actual results could differ from those estimates. Making estimates requires management to exercise significant judgment and it is reasonably possible that management's estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements could change in the near term due to one of more future confirming events.

Assets Held for Sale and Discontinuing Operations

In accordance with ASC 205-20 “Presentation of Financial Statements: Discontinued Operations”, a disposal of a component of an entity or a group of components of an entity is required to be reported as discontinuing operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. In the period in which the component meets held-for-sale or discontinued operations criteria the major current assets, non-current assets, current liabilities, and non-current liabilities shall be reported as components of total assets and liabilities separate from those balances of the continuing operations. At the same time, the results of all discontinuing operations, less applicable income taxes, shall be reported as components of net loss separate from the net loss of continuing operations.

The Company’s Eton subsidiary met the definition of a discontinuing operation as of June 30, 2024. Accordingly, the Company has classified the results of Eton as discontinuing operations in its unaudited condensed consolidated statements of operations and comprehensive loss for all periods presented. All assets and liabilities associated with Eton were classified as assets and liabilities of discontinuing operations in the unaudited condensed consolidated balance sheets for the periods presented. All amounts included in the notes to the unaudited condensed consolidated financial statements relate to continuing operations unless otherwise noted. For additional information, see Note 18, “Assets held for Sale and Discontinuing Operations”.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current presentation. The Company separately presented interest income and interest expense that had previously been combined as “Interest expense, net” on the condensed consolidated statement of operations and comprehensive loss for the three and six months ended June 30, 2023. The Company also separately presented the provision for credit losses line on the condensed consolidated statement of cash flows, which had previously been combined with the change in accounts receivable. These reclassifications had no impact on net loss for the three and six months ended June 30, 2023 or net cash used in operating activities for the six months ended June 30, 2023.

Restricted Cash

In accordance with ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, the Company explains the change during the period in the total of cash, cash equivalents and restricted cash, and includes restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheet dates that comprise the total of the same such amounts shown in the condensed consolidated statements of cash flows for all periods presented herein (in thousands):


	June 30, 2024		December 31, 2023
Cash and cash equivalents	$	6,397	$	1,570
Restricted cash		100		175
Total cash, cash equivalents, and restricted cash as shown in the consolidated statements of cash flows	$	6,497	$	1,745

Accounts Receivable

Accounts receivable is comprised of amounts due from third-party payors recorded at the invoice amount and does not bear interest. The Company reports accounts receivable net of estimated contractual adjustments and any allowance for credit losses. The Company reviews accounts receivable on an ongoing basis to determine collectability. The Company maintains an allowance for credit losses based on its assessment of the collectability of the amounts owed to the Company by its customers. The Company considers the following in determining the level of allowance required: its customer’s payment history, the age of the receivable, the credit quality of its customers, the general financial condition of its customer base and other factors that may affect the customers’ ability to pay. The Company writes off accounts against the allowance for credit losses when they are deemed to be uncollectible. Net accounts receivable amounted to $1.3 million and $5.4 million as of June 30, 2024 and December 31, 2023, respectively. Net accounts receivable include an allowance for credit losses of $1.0 million and $1.2 million at June 30, 2024 and December 31, 2023, respectively, for those accounts deemed uncollectible by the Company. The allowance for credit losses consists of the following activity (in thousands):


Allowance for credit losses at December 31, 2023	$	1,197
Provision for credit losses		205
Write-offs		(397	)
Allowance for credit losses at June 30, 2024	$	1,005

Recent Accounting Pronouncements Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This standard was issued in response to the SEC’s disclosure update and simplification initiative, which affects a variety of topics within the ASC. The amendments apply to all reporting entities within the scope of the affected topics unless otherwise indicated. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is currently evaluating the impact this guidance will have on its consolidated financial statement disclosures.

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This standard requires the Company to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and are included within each reported measure of segment operating results. The standard also requires the Company to disclose the total amount of any other items included in segment operating results, which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items. In addition, the standard also requires disclosure of the CODM’s title and position, as well as detail on how the CODM uses the reported measure of segment operating results to evaluate segment performance and allocate resources. The standard also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. This standard is effective for annual financial reporting in fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. The Company is currently evaluating the potential impact that this new standard will have on its consolidated financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740). This standard requires the Company to provide further disaggregated income tax disclosures for specific categories on the effective tax rate reconciliation, as well as additional information about federal, state/local and foreign income taxes. The standard also requires the Company to annually disclose its income taxes paid (net of refunds received), disaggregated by jurisdiction. This guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is to be applied prospective basis, although optional retrospective application is permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statement disclosures.

As of June 30, 2024 and December 31, 2023, all short-term investments held by the Company had remaining contractual maturities of one year or less.

As of June 30, 2024 and December 31, 2023, the Company reviewed its investment portfolio for declines in fair value below the amortized cost basis to determine whether the impairment, if any, is due to credit-related or other factors. In determining whether the decline in fair value of these securities was related to a credit loss, the Company evaluated whether it intended to sell the security and whether it was more likely than not that the Company would be required to sell the security before recovering its amortized cost basis. During the three and six months ended June 30, 2024 and 2023, the Company concluded that there were no impairments related to credit losses for its investments in securities.

Goodwill and Other Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

In 2019, SGI sold SGI-DNA to GATTACA Mining, LLC. As part of the transaction, the Company acquired its intangible assets with resulting goodwill. The goodwill carries a fair value of approximately $3.5 million. In connection with the Eton acquisition in November 2021, the excess of the purchase price over the fair value of the net identifiable tangible and intangible assets acquired has been assigned to goodwill at a fair value of $11.4 million.

The Company currently has two reporting units: Telesis Bio and Eton. Goodwill is tested quantitatively for impairment at the reporting unit level annually in the fourth quarter, or more frequently when events or changes in circumstances indicate that the asset might be impaired. During the fourth quarter of 2023, the decrease to the Company’s market capitalization, measured as the price of the Company’s common stock multiplied by common shares outstanding, and the early repayment of $15.0 million under the 2022 Term Loan Agreement lead the Company to conclude it was more likely than not that the fair value of one or more reporting units was below its carrying amount. A quantitative goodwill assessment was then performed for both of the Company's reporting units using a combination of techniques, including an income approach and a market-based approach. Based on the results of the quantitative goodwill assessment for the Eton reporting unit, the Company recorded an impairment charge of $11.4 million to reduce that reporting unit's carrying amount of goodwill to zero. Based on the results of the quantitative goodwill assessment for the Telesis Bio reporting unit, there was no impairment to that reporting unit's goodwill balance of $3.5 million as of December 31, 2023. Should the market value of the Company’s common stock decline, additional impairment charges may be recorded in the future. For the three and six months ended June 30, 2024 and 2023, the Company did not record any impairment of goodwill.

Other Intangible Assets

Other intangible assets acquired in the sale of SGI-DNA to GATTACA Mining, LLC include the rights to technology and the SGI-DNA trade name. The technology was valued at approximately $3.2 million with a seven year useful life. The Company evaluated its other intangible assets and concluded that there was no impairment during the three and six month periods ended June 30, 2024 and 2023.

Other intangible assets, net consists of the following (in thousands):


	June 30, 2024
	Gross Carrying Value		Accumulated Amortization			Net Carrying Value
Intellectual property	$	3,150	$	(2,400	)	$	750
Total	$	3,150	$	(2,400	)	$	750


	December 31, 2023
	Gross Carrying Value		Accumulated Amortization			Net Carrying Value
Intellectual property	$	3,150	$	(2,176	)	$	974
Total	$	3,150	$	(2,176	)	$	974

Amortization expense for each of the three months ended June 30, 2024 and 2023 was approximately $0.1 million, and amortization expense for each of the six months ended June 30, 2024 and 2023 was approximately $0.2 million.

The following table summarizes the estimated future amortization expense of the intangible assets as of June 30, 2024 (in thousands):


Years ending December 31:	Amortization of Intangible Assets

ORGANIZATION, OPERATIONS, AND LIQUIDITY

Business

Telesis Bio Inc. (the Company) was incorporated in the state of Delaware in March 2011, as Synthetic Genomics Solution, Inc., a wholly owned subsidiary of Synthetic Genomics, Inc. (SGI). The Company changed its name to SGI-DNA, Inc. (SGI-DNA) in February 2013, to Codex DNA, Inc. in March 2020, and then to Telesis Bio Inc. in November 2022. The Company manufactures and sells laboratory equipment, specifically synthetic biology instruments, reagents and associated products and related services, primarily to pharmaceutical and academic laboratories worldwide.

The Company has two wholly owned subsidiaries:

•

SGI-DNA Limited is a United Kingdom company focused on sales and marketing activities.

•

EtonBio Inc., a California corporation (Eton), is a San Diego-based biotech company specializing in synthetic biology products and services, including DNA sequencing and oligo synthesis, for the global academic research, pharmaceutical, and biotechnology industries. Eton also markets DNA prep services and products such as antibodies, peptides, and metabolism assay kits. Eton met the definition of a discontinuing operation as of June 30, 2024 (Notes 2 and 18).

Going Concern

Since its inception, the Company has devoted substantially all of its efforts to raising capital, commercializing its current products, and developing new product offerings. The Company is subject to a number of risks similar to those of other companies conducting high-risk, early-stage research and development of products. Principal among these risks are a dependence on key individuals and intellectual property, competition from other products and companies, and the technical risks associated with the successful research, development and manufacturing of its products. The Company’s success is dependent upon its ability to continue to raise additional capital in order to fund ongoing research and development, commercialize its products, generate revenue, meet its obligations, and, ultimately, become profitable.

Products currently under development will require significant additional research and development efforts. These efforts require significant amounts of additional capital, adequate personnel and infrastructure.

Since inception, the Company has incurred cumulative operating losses and negative cash flows from operations. These operating losses and negative cash flows have been financed principally from the issuance of equity securities and debt. In the future, such capital may not be available in sufficient amounts, on terms acceptable to the Company, or at all. Risks to which the Company is exposed include uncertainties related to the ability to achieve revenue-generating products; current and potential competitors with greater financial, technological, production, and marketing resources; dependence on key management personnel; and raising additional capital, as needed.

Under Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40), the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that its financial statements are issued. The Company has incurred losses and negative cash flows from operations in each year since its inception. As of June 30, 2024, the Company had an accumulated deficit of $182.7 million. In June 2021, the Company received $112.5 million in net proceeds upon completion of its IPO, and in June 2023 received $26.4 million in net proceeds from the sale of preferred stock and warrants. The Company has also received $8.0 million in upfront payments and $7.5 million in milestone payments under its collaboration with Pfizer Inc. (see Note 17). Until such time, if ever, as the Company can generate substantial product revenue and/or collaboration revenue and achieve sustained profitability, the Company expects to finance its cash needs through a combination of equity offerings, collaborations, strategic alliances, licensing arrangements and other sources of funding. On August 9, 2022, the Company entered into (i) a Credit, Security and Guaranty Agreement (the 2022 Term Loan Agreement), with the Company and MidCap Financial Trust, and (ii) a

Credit, Security and Guaranty Agreement (the 2022 Revolving Loan Agreement) (the 2022 Revolving Loan Agreement, and together with the 2022 Term Loan Agreement, the 2022 Loan Agreements, and the extensions of credit thereunder are referred to herein as the 2022 Term Loan and the 2022 Revolving Loan, respectively), with MidCap Funding IV Trust (together with MidCap Financial Trust, MidCap). On August 9, 2022, the Company borrowed $20.0 million under the terms of the 2022 Term Loan Agreement. As of September 30, 2023, the Company was not in compliance with the minimum revenue covenants of the 2022 Term Loan Agreement. As a result of this non-compliance, MidCap required the Company to repay $15.0 million in November 2023 under the 2022 Term Loan Agreement and the parties subsequently entered into Amendment No. 3 to Credit Security and Guaranty Agreement (Amendment No. 3) on November 24, 2023, which amended the 2022 Loan Agreements. As of June 30, 2024, the Company was in compliance with the covenants under the amended 2022 Loan Agreements. The Company intends to seek additional financing, however, the Company may not be able to raise cash on terms acceptable to the Company or at all. There can be no assurance that the Company will be successful in obtaining sufficient additional funding. Financings, if available, may be on terms that are dilutive to stockholders, and the prices at which new investors would be willing to purchase the Company’s securities may be lower than the current price of its common stock. The holders of new securities may also receive rights, preferences or privileges that are senior to those of existing holders of common stock. If additional financing is not available or is not available on acceptable terms, the Company could be forced to delay, limit, reduce or terminate product development or future commercialization efforts or grant rights to develop and market products that the Company would otherwise prefer to develop and market itself. These factors raise substantial doubt about the Company’s ability to continue as a going concern. Based upon the Company’s current level of expenditures, management believes there currently are insufficient financial resources to fund the Company’s operations for at least twelve months from the filing date of this Quarterly Report. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

COMMITMENTS AND CONTINGENCIES

Litigation

The Company may become involved in various claims, suits, and legal proceedings from time to time in the ordinary course of its business. The Company accrues a liability when it believes that it is both probable and the amount of loss can be reasonably estimated. While the outcome of such claims, lawsuits or other proceedings cannot be predicted with certainty, management expects that any liability, to the extent not provided for by insurance or otherwise, will not have a material adverse effect on the Company’s condensed consolidated financial position or results of operations.

Leases

The Company’s non-cancelable lease commitments are described in Note 8.

Registration Rights

In connection with the issuance of Redeemable Convertible Preferred Stock, the Company also entered into a Registration Rights Agreement (the Registration Rights Agreement) and pursuant to its terms, filed a registration statement on Form S-3 with the SEC on July 27, 2023 (File No. 333-273491) covering the resale of shares of common stock issuable upon conversion of the Redeemable Convertible Preferred Stock (the Registration Statement). Among other requirements, the Company is required to use its commercially reasonable efforts to keep the Registration Statement continuously effective until the date that the Registrable Securities (as defined in the Registration Rights Agreement) are no longer Registrable Securities. Upon an event of default and on each monthly anniversary of the default, until cured, the Company is required to pay to each holder of Redeemable Convertible Preferred Stock an amount of liquidated damages in cash, equal to the product of 1.5% multiplied by the aggregate price paid by such holder for the purchase of Redeemable Convertible Preferred Stock. The maximum aggregate liquidated damages payable will be equal to 6% of the aggregate price paid for the purchase of Redeemable Convertible Preferred Stock. Based on the aggregate purchase price for the Company's outstanding shares of Redeemable Convertible Preferred Stock, the maximum aggregate liquidated damages, should an event of default occur in the future, is $1.7 million (Note 19).

The impact of Amendment No. 2 was to (i) increase the interest rate on the 2022 Term Loan, (ii) increase the interest rate floor on the 2022 Term Loan and the 2022 Revolving Loan, (iii) increase the exit fee, (iv), reset the prepayment penalty, (v) require the lender’s consent for activation of future incremental borrowings under the 2022 Term Loan Agreement, and (vi) reset the minimum net revenue covenant.

The 2022 Term Loan Agreement, as amended, provides for a secured term loan facility in an aggregate principal amount of up to $30.0 million, comprised of (i) a tranche one term loan of up to $20.0 million (Tranche One), (ii) a tranche two term loan of up to $5.0 million (Tranche Two), and (iii) a tranche three term loan of up to $5.0 million (Tranche Three). Tranche Two and Tranche Three require MidCap's consent in order for the Company to draw down the additional borrowings. The 2022 Revolving Loan Agreement provides for a secured revolving loan facility in an aggregate principal amount of up to $10.0 million, subject to a borrowing base equal to percentages of eligible accounts receivable and inventory as determined in accordance with the 2022 Revolving Loan Agreement. The 2022 Term Loan and 2022 Revolving Loan mature on August 1, 2027.

Tranche One was fully funded on August 9, 2022 to pay transaction fees incurred in connection with the 2022 Loan Agreements and to repay in full the Company’s borrowings under its existing loan facility under the 2021 Loan Agreement with Silicon Valley Bank, with the remaining amount to be used be for general corporate purposes. Subject to certain terms and conditions of the 2022 Term Loan Agreement including MidCap's consent, Tranche Two was available between January 1, 2023, and September 30, 2023, following the Company’s achievement of specified milestones relating to minimum net revenues and minimum net cash proceeds from equity financing, but was not exercised. Subject to certain terms and conditions of the 2022 Term Loan Agreement including MidCap's consent, Tranche Three may become available between September 30, 2024, and March 31, 2025. The proceeds of Tranche Three, if available, may be used for working capital and general corporate purposes.

As of September 30, 2023, the Company was not in compliance with certain minimum revenue covenants of the 2022 Term Loan Agreement. As a result of this non-compliance, MidCap had the ability to immediately call the balance of the loan, along with a 5.5% exit fee and 3.0% prepayment penalty, amounting to a total repayment obligation of approximately $21.7 million for the 2022 Term Loan, plus a $0.3 million prepayment penalty for the 2022 Revolving Loan.

On November 24, 2023, the Company entered into Amendment No. 3 to the 2022 Loan Agreements (Amendment No. 3). The impact of Amendment No. 3 was to (i) repay $15.0 million in November 2023 under the 2022 Term Loan Agreement and (ii) grant MidCap a warrant to purchase 15,278 shares of common stock at an exercise price per share equal to the 10-day volume weighted average price of the Company's common stock immediately prior to the date of Amendment No. 3. In exchange for the Company doing the foregoing, MidCap (i) waived all existing defaults under the 2022 Loan Agreements, (ii) reset revenue covenants under the 2022 Term Loan Agreement, (iii) waived the prepayment penalty related to the $15.0 million repayment and reduced the prepayment penalty for the remaining outstanding balance under the 2022 Term Loan Agreement to 1%, (iv) froze any future extensions of credit under the 2022 Revolving Loan Agreement and (v) reduced the exit fee payable upon complete repayment of amounts left outstanding at the end of term by $350,000, with the remaining $750,000 of exit fees to be payable at maturity.

The 2022 Term Loan, as amended, bears interest at a floating rate based on an adjusted term secured overnight financing rate (SOFR) plus 0.1% (subject to a floor of 3.50%) for a one-month interest period, plus a margin of 6.75%. Interest on the 2022 Term Loan is payable monthly in arrears on the first day of each month and at maturity. For the six months ended June 30, 2024, the effective interest rate on outstanding borrowings was approximately 17.01%.

Following an initial interest-only period, beginning on August 1, 2025, the outstanding principal amount of the 2022 Term Loan is repayable in twenty-four equal monthly principal payments, with all remaining outstanding principal, together with all accrued and unpaid interest, due at maturity. The 2022 Term Loan, as amended, may be voluntarily prepaid in full, but not in part, at any time and are also subject to mandatory prepayments with the net proceeds of certain dispositions and casualty events, subject to specified thresholds and reinvestment rights. Prepayments are subject to prepayment premiums of 1.00% of the amount prepaid. Once repaid, the 2022 Term Loan may not be reborrowed. The Company is also obligated to pay an exit fee equal to $750,000 and other customary fees for a credit facility of this size and type. The exit fee is being accrued through interest expense using the effective interest method.

The Company may borrow, repay and reborrow the 2022 Revolving Loan until August 1, 2027, at which time the revolving commitments will terminate and all outstanding revolving loans, together with all accrued and unpaid interest, must be repaid. The proceeds of the 2022 Revolving Loan may be used for working capital needs and general corporate purposes. As of June 30, 2024, no amount of the 2022 Revolving Loan was outstanding under the 2022 Revolving Loan Agreement. On November 24, 2023, MidCap froze any future extensions of credit under the 2022 Revolving Loan Agreement due to the event of default discussed above.

The 2022 Revolving Loan would bear interest at a floating rate based on an adjusted term SOFR (subject to a floor of 1.50%) for a one-month interest period, plus a margin of 3.00%. Interest on the 2022 Revolving Loan would be payable monthly in arrears on the first day of each month and at maturity. Prior to November 24, 2023, the Company was obligated to pay an unused line fee equal to 0.50% per annum on the unused portion of the available revolving commitments, a fee for failure to maintain a minimum balance under the 2022 Revolving Loan Agreement, and other customary fees for a credit facility of this size and type.

The obligations of the Company and any future guarantors under the 2022 Loan Agreements are secured by liens on substantially all of the Company's assets.

The 2022 Loan Agreements, as amended, require the Company to comply with (i) a minimum net revenue covenant and (ii) a minimum cash covenant, which requires certain unrestricted cash to be greater than or equal to $7.0 million at all times.

The 2022 Loan Agreements, as amended, contain customary affirmative and negative covenants, including covenants limiting the ability of the Company and its subsidiaries, among other things, to incur debt, grant liens, make distributions, enter certain restrictive agreements, pay or modify subordinated debt, dispose of assets, make investments and acquisitions, enter into certain transactions with affiliates, and undergo certain fundamental changes, in each case, subject to limitations and exceptions set forth in the 2022 Loan Agreements.

The 2022 Loan Agreements, as amended, contain customary events of default that include, among other things, certain payment defaults, cross defaults to certain other contracts and indebtedness, covenant defaults, inaccuracy of representations and warranties, bankruptcy and insolvency defaults, judgment defaults, change of control defaults, defaults related to the failure to remain registered with the SEC and listed for trading on the Nasdaq Stock Market, and a material adverse change default.

Upon the occurrence and during the continuance of an event of default under the 2022 Loan Agreements, as amended, the respective administrative agent, if requested by the respective lenders, may, among other things, (i) suspend or terminate commitments, as well as obligations of the relevant administrative agent and lenders, (ii) declare all outstanding obligations under the applicable agreement (including principal and accrued and unpaid interest) immediately due and payable, and (iii) exercise the other rights and remedies provided for under the applicable agreement. The 2022 Loan Agreements provide that, under certain circumstances, a default interest rate will apply on all obligations under such agreement during the existence of an event of default, at a per annum rate equal to 2.0% above the applicable interest rate.

The Company bifurcated a derivative liability related to the acceleration clause triggered upon an event of default (contingent put option) under the 2022 Term Loan Agreement. The contingent put option liability is classified as a derivative liability on the consolidated balance sheet. As of June 30, 2024, the estimated fair value of the contingent put option liability was $36 thousand, which was determined by using a risk-neutral valuation model wherein the fair value of the underlying debt facility is estimated, both with and without the presence of the default provisions, holding all other assumptions constant (Note 3).

As of June 30, 2024, the estimated future principal payments due were as follows (Note 19):

Leases [Abstract]

LEASES

As of June 30, 2024, the Company had three outstanding leases for office and laboratory space and scientific manufacturing equipment with remaining terms between approximately one and nine years. The Company has also entered into certain short-term leases with a term of one year or less. These leases are not included within the Company’s right-of-use assets or lease liabilities due to the Company’s election of the practical expedient recognition exemption for short-term leases.

Corporate Headquarters

In September 2021, the Company entered into the Wateridge Pointe lease for future office and laboratory space at 10421 and 10431 Wateridge Circle, San Diego, California (the Wateridge Pointe Lease), and concurrently signed a second amendment to the operating lease agreement for its corporate headquarters located at 9535 Waples Street, San Diego, California (the Second Amendment). Under the Second Amendment, the lease at 9535 Waples Street terminated upon the occupancy of office and laboratory space at 10431 Wateridge Circle in March 2023. The Wateridge Pointe Lease provides for a tenant improvement allowance for the renovation and build-out of the facilities up to $185.00 per square foot, or approximately $12.3 million, with an additional allowance of up to $10.00 per square foot, or approximately $0.7 million if properly requested by the Company. The lessor is solely responsible for the management and payment of the tenant improvements and these expenses will be recorded as lessor improvements under Accounting Standards Codification (ASC) 842 guidance. Combined rent for the two buildings under the Wateridge Pointe Lease is approximately $3.9 million per year, subject to annual increases of 3%. The Wateridge Pointe Lease provides for a 10 year and 3 month term and the Company is entitled to one option to extend the lease term for an additional five years. Occupancy of 10431 Wateridge Circle and the corresponding termination of the lease at 9535 Waples Street occurred in the first quarter of 2023. Occupancy and commencement of the 10421 Wateridge Circle lease occurred in the second quarter of 2023.

In January 2024, the Company signed a first amendment to the Wateridge Pointe Lease for its corporate headquarters located at 10421 and 10431 Wateridge Circle (the 2024 First Amendment). Under the 2024 First Amendment, the landlord shall apply the existing security deposit of $0.4 million toward the base rent for the six-month period January 1 through June 30, 2024, with the $1.5 million balance of the base rent during that period abated. Under the 2024 First Amendment, escalating base rent payments will be $0.4 million to $0.5 million per month from July 2024 through July 2033 (Note 19).

Equipment

The Company entered into finance lease agreements for equipment in November 2022 (the 2022 Equipment Lease), and in August 2023 (the 2023 Equipment Lease). The terms of the leases commenced when the equipment was delivered and placed into use which occurred in November 2022 and August 2023, respectively, and accordingly the related right-of-use assets and lease liabilities were recognized on the consolidated balance sheets at their respective commencement dates. The 2022 Equipment Lease expires in October 2025 and the 2023 Equipment Lease expires in August 2026.

COLLABORATION

17.

COLLABORATION

In December 2021, the Company entered into a Research Collaboration and License Agreement (Pfizer Agreement) with Pfizer Inc. (Pfizer), pursuant to which the Company agreed to collaborate with Pfizer to further develop the Company's novel enzymatic DNA synthesis technology for Pfizer’s use in its research and development of mRNA-based vaccines and biotherapies. The financial terms of the deal include an upfront payment from Pfizer to the Company, along with success-based technical milestone payments that could be earned in the near term. The Company is also eligible to receive additional milestone payments based on the achievement of specified development, regulatory and commercialization goals associated with any products developed from the application of the Company’s technology developed and licensed under the Pfizer Agreement.

The Company granted Pfizer a non-exclusive, worldwide license to use the Company’s enzymatic DNA synthesis technology for purposes of researching, developing, manufacturing and commercializing pharmaceutical and biopharmaceutical products and a limited-time option to convert such license to exclusive for specific applications.

Under the Pfizer Agreement, Pfizer made an upfront payment of $8.0 million at the time of execution and subsequent milestone payments of $7.5 million. If the Company meets certain additional technical milestones defined in the Pfizer Agreement, the Company will be eligible to receive an additional $2.5 million in near-term milestone payments.

In addition to the upfront payment and technical milestone payments, Pfizer has agreed to make milestone payments to the Company upon the products meeting certain clinical milestones, with each product (other than exclusive products) being eligible for milestone payments up to $20.0 million if it were to meet the applicable clinical milestones and the first exclusive product in each exclusive field being eligible for milestone payments up to $55.0 million if it were to meet the applicable clinical milestones. Pfizer has also agreed to pay the Company up to $60.0 million in sales milestones for products (other than exclusive products) if aggregate net sales of such products meet certain thresholds and up to $180.0 million in sales milestones for exclusive products if aggregate net sales of the exclusive products meet certain thresholds. Provided the Pfizer Agreement remains in place, Pfizer will also pay escalating royalties from a low to mid-fraction of one percent of net sales of all products. Pfizer’s obligations to pay royalties with respect to a product within a country will expire after specific criteria including such product no longer being covered by patent rights licensed to Pfizer by the Company in such country. Royalty payments are subject to reduction after the introduction of a biosimilar product in such country by a third party.

The Company assessed the Pfizer Agreement in accordance with ASC 606, Revenue from Contracts with Customers, and concluded that Pfizer is a customer based on the agreement's structure. The Company identified a single combined performance obligation under the arrangement for the performance under the research plan, technology transfer between the parties, participation in the Joint Research Committee, research licenses exchanged by the parties and the non-exclusive commercial license. In addition, the Company identified a material right for the option granted to Pfizer to extend the research term by an additional year. The $8.0 million upfront payment represents the transaction price at inception.

The Company determined that the $8.0 million upfront payment represents the entirety of the consideration to be included in the transaction price as of the outset of the arrangement. The potential milestone payments that the Company may have been eligible to receive were initially excluded from the transaction price at the outset of the arrangement because (i) all technical and development milestone payments did not meet the criteria for inclusion using the most-likely amount method and (ii) the Company recognizes as revenue sales-based milestones and royalties when the related sales occur. To date, the Company has achieved technical milestones associated with the research plan and recognized revenue associated with the milestone achievements totaling $7.5 million. As of June 30, 2024 no other milestones or royalties have been deemed likely to be achieved or have been achieved.

In accordance with ASC 606, the Company allocated the transaction price, comprising the upfront payment of $8.0 million, based on the stand-alone selling price of the combined performance obligation and the material right. Based on management's analysis, the material right was allocated $0.3 million of the transaction price, while the combined performance obligation was allocated $7.7 million of the transaction price.

The $7.7 million of revenue allocated to the combined performance obligation was recognized using the input method based on time elapsed as compared to the research term of 24 months, and the $0.3 million of revenue allocated to the material right was to be recognized over the third year of services performed under the research plan in the event the option to extend the research plan was exercised, or when the option expired in the event the option to extend the research plan was not exercised. During 2022, the option expired unexercised, and the $0.3 million was recognized.

During the three and six months ended June 30, 2024, the Company did not recognize any revenue related to the Pfizer Agreement. During the three and six months ended June 30, 2023, the Company recognized $3.5 million and $4.4 million, respectively, of revenue related to the Pfizer Agreement. As of June 30, 2024 and December 31, 2023, there was no deferred revenue related to the Pfizer Agreement.

ASSETS HELD FOR SALE AND DISCONTINUING OPERATIONS

ASSETS HELD FOR SALE AND DISCONTINUING OPERATIONS

The Company has made a strategic decision to sell its subsidiary, Eton. The sale is expected to be completed during the fiscal quarter ending September 30, 2024. Upon closing of the sale, the Company will deconsolidate the assets and liabilities of Eton. As of June 30, 2024, Eton met the held for sale criteria and is reflected as a discontinued operation in the consolidated financial statements for all periods presented. Additionally, the related assets and liabilities have been reported as assets and liabilities held for sale in the Company's condensed consolidated balance sheets as of June 30, 2024 and December 31, 2023.

Because the carrying value of the net assets of Eton exceeds the estimated fair value, the Company determined that Eton's held for sale net assets had been impaired. After performing quantitative testing, in which the Company used the expected consideration of $1.4 million as the fair value of the underlying net assets, the Company recorded a $0.2 million impairment of the net assets. The impairment loss has been included in the loss from discontinuing operations in the accompanying condensed consolidated financial statements.

The Company's condensed consolidated balance sheets, condensed consolidated statements of operations and comprehensive loss, and condensed consolidated statements of cash flows report discontinuing operations separate from continuing operations. The Company's condensed consolidated statement of Redeemable Convertible Preferred Stock and Stockholders' (Deficit) Equity combines continuing and discontinuing operations. A summary of financial information related to the Company's discontinuing operations is as follows.

The following table presents the results of the discontinuing operations for the three and six months ended June 30, 2024 and 2023 (in thousands):

STOCK-BASED COMPENSATION

For the three months ended June 30, 2024 and 2023 and the six months ended June 30, 2024 and 2023, the Company recorded stock-based compensation expense of approximately $0.9 million, $1.0 million, $1.6 million and $2.2 million, respectively. No income tax benefit was recognized in the accompanying condensed consolidated statements of operations and comprehensive loss for the Company’s equity incentive plan.

The Company’s board of directors approved the adoption of the SGI-DNA, Inc. 2019 Stock Plan (the 2019 Plan) in March 2019. The 2019 Plan permitted the Company to grant options and restricted stock units for up to 308,011 shares of the Company’s common stock. On March 3, 2021, the Company’s board of directors and stockholders approved the termination of the 2019 Plan and the

adoption of the 2021 Equity Incentive Plan (the 2021 Plan). 333,334 shares of common stock were reserved for issuance under the 2021 Plan.

In June 2021, the Company established the 2021 Stock Incentive Plan (the 2021 SIP). The 2021 SIP became effective on the effective date of the IPO, at which time the Company ceased granting awards under the 2021 Plan. The 2021 SIP allows the Company’s board of directors or its compensation committee to grant equity-based awards to the Company’s employees, directors and consultants. A total of 194,445 shares of common stock were initially reserved for issuance under the 2021 SIP, plus the number of shares (not to exceed 136,665 shares) consisting of (i) the shares of common stock that were available for the issuance of awards under the 2021 Plan at the time the 2021 SIP became effective, which ceased to be available for future issuance under the 2021 Plan at such time and (ii) any shares subject to outstanding options or other share awards that were granted under the 2019 Plan and the 2021 Plan that terminate or expire prior to exercise or settlement; are forfeited because of the failure to vest; or are reacquired or withheld (or not issued) to satisfy a tax withholding obligation or the purchase or exercise price. In addition, the number of shares reserved and available for issuance under the 2021 SIP automatically increases, beginning on January 1, 2022 and on each January 1 thereafter by the lesser of (i) 875,000 shares, (ii) 5% of the outstanding number of shares of common stock on the immediately preceding December 31, or (iii) such lesser number of shares as determined by the Company’s board of directors or a designated committee thereof. As of June 30, 2024, the number of shares of common stock reserved for issuance under the 2021 SIP was 193,804.

Stock option activity under the 2019 Plan, the 2021 Plan and the 2021 SIP for the six months ended June 30, 2024 is as follows:


	Number of options			Weighted average exercise price		Weighted average remaining contractual term (in years)		Aggregate intrinsic value (in thousands)
Balances at December 31, 2023		314,757		$	34.22		8.5	$	1
Options granted		34,139			7.25
Options exercised		(480	)		7.02
Options cancelled		(31,738	)		23.60
Balances at June 30, 2024		316,678		$	32.42		8.2	$	—
Vested and expected to vest at June 30, 2024		301,642		$	32.30		8.2	$	—
Exercisable at June 30, 2024		140,004		$	42.10		7.6	$	—

There were 34,139 options granted during the six months ended June 30, 2024. The weighted average grant date calculated fair value of options granted during the six months ended June 30, 2024 was $4.08 per share. The aggregate intrinsic value of options exercised during the six months ended June 30, 2024 and 2023 was $2 thousand and $94 thousand, respectively.

The calculated value of option grants during the six months ended June 30, 2024 was estimated using the Black-Scholes option pricing model with the following weighted average assumptions:


		Six Months Ended
		June 30, 2024
Risk free interest rate		4.4%
Expected dividend yield		—%
Expected term		6.0 years
Expected volatility		55.2%

The Company has granted restricted stock units with vesting based conditions. Unvested shares of restricted common stock may not be sold or transferred by the holder. They are legally issued and outstanding. These restrictions lapse accordingly to the time-based vesting of each award.

A summary of the restricted stock unit activity during the six months ended June 30, 2024 is as follows:


	Restricted Stock Units			Weighted-Average Grant Date Fair Value
Unvested at December 31, 2023		32,741		$	48.26
Granted		15,984			6.56
Vested		(13,308	)		44.66
Cancelled		(863	)		103.35
Unvested at June 30, 2024		34,554		$	28.98

Effective in connection with the IPO, the Company established the 2021 Employee Stock Purchase Plan (the ESPP). The maximum number of shares of common stock that may be issued under the ESPP was initially 19,445. Additionally, the number of shares reserved and available for issuance under the ESPP automatically increases each January 1, beginning on January 1, 2022 and each January 1 thereafter, by the lesser of (i) 58,334 shares of common stock, (ii) 1% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, or (iii) such smaller number of shares of common stock as the Company’s board of directors may designate. As of June 30, 2024, the number of shares of common stock that may be issued under the ESPP is 45,060.

For the six months ended June 30, 2024, 3,436 shares of common stock were issued under the ESPP.

NET LOSS PER SHARE

Net loss per share

Basic and diluted net loss per share attributable to common stockholders was calculated as follows (in thousands, except share and per share amounts):


	Three Months Ended June 30,						Six Months Ended June 30,
	2024			2023			2024			2023
Numerator:
Net loss from continuing operations	$	(11,561	)	$	(7,763	)	$	(19,471	)	$	(18,398	)
Net loss from discontinuing operations		(1,024	)		(524	)		(1,751	)		(1,008	)
Less: Redeemable Convertible Preferred Stock Dividends		(596	)		(153	)		(1,181	)		(153	)
Net loss attributable to common stockholders	$	(13,181	)	$	(8,440	)	$	(22,403	)	$	(19,559	)
Denominator:
Weighted average common stock outstanding - basic and diluted		1,730,210			1,654,127			1,700,596			1,651,053
Net loss per share from continuing operations attributable to common stockholders—basic and diluted	$	(7.03	)	$	(4.79	)	$	(12.14	)	$	(11.24	)
Net loss per share from discontinuing operations attributable to common stockholders—basic and diluted	$	(0.59	)	$	(0.32	)	$	(1.03	)	$	(0.61	)
Net loss per share attributable to common stockholders - basic and diluted	$	(7.62	)	$	(5.10	)	$	(13.17	)	$	(11.85	)

The Company’s potential dilutive securities have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of shares of common stock outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential shares of common stock from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	June 30,

Stock options to purchase common stock		316,678		319,725
Restricted stock units that vest into common stock		34,554		22,565

Depreciation expense for the three months ended June 30, 2024 and 2023 was $0.4 million and $0.3 million respectively, and depreciation expense for the six months ended June 30, 2024 and 2023 was $0.8 million and $0.6 million respectively, and is included in operating expenses. As of June 30, 2024, the Company recorded an impairment charge of $1.0 million to write down to fair value certain property and equipment used in its corporate headquarters. The Company determined the net book value of such assets exceeded their fair value as a result of idle nature and the high likelihood the assets would be sold or abandoned significantly before the end of their previously estimated useful life. There was no impairment recorded during the three and six months ended June 30, 2023.

Contingent Put Option Liability

The contingent put option liability consists of the fair value of the contingent interest feature and acceleration clause (contingent put option) under the 2022 Term Loan Agreement (see Note 9). The fair value of the contingent put option liability was based on significant inputs not observable in the market, which represent a Level 3 measurement within the fair value hierarchy. The Company’s valuation of the contingent put option liability utilized a risk-neutral valuation model wherein the fair value of the underlying debt facility is estimated, both with and without the presence of the default provisions, holding all other assumptions constant. The Company assesses these assumptions and estimates each reporting period as additional information impacting the assumptions are obtained. Changes in the fair value of the contingent put option liability are recognized in other (expense) income, net as part of the change in fair value of derivative liabilities in the condensed consolidated statements of operations and comprehensive loss. The significant inputs not observable in the market consist of the adjusted market rate of debt and the probability of default. As of both June 30, 2024 and December 31, 2023, the adjusted market rate of debt was 12.48%, and the probability of default was 45%. A significant change in those inputs could cause a significant change in valuation.

The following table provides a roll-forward of the aggregate fair value of the Company’s derivative liabilities for which fair value is determined using Level 3 inputs (in thousands):


	Contingent Put Option Liability
Fair value at December 31, 2023	$	36

REDEEMABLE CONVERTIBLE PREFERRED STOCK

REDEEMABLE CONVERTIBLE PREFERRED STOCK

Redeemable Convertible Preferred Stock Financing

On May 31, 2023, the Company executed a Redeemable Convertible Preferred Stock and Warrant Purchase Agreement (the Agreement) for the purposes of raising capital in the aggregate amount of up to $28.0 million by the means of issuance of Redeemable Convertible Preferred Stock and warrants.

On June 1, 2023, the Company filed a Certificate of Designation of Redeemable Convertible Preferred Stock of Telesis Bio (the Certificate of Designation), to set forth the rights, privileges and preferences of the Company's Redeemable Convertible Preferred Stock (the Redeemable Convertible Preferred Stock).

On June 5, 2023, the Company issued 280,000 shares of Redeemable Convertible Preferred Stock, which are convertible at any time into shares of the Company's common stock, and warrants to purchase an aggregate of 987,325 shares of the Company's common stock, for a total purchase price of $28.0 million, plus an additional 19,749 warrants to purchase the Company's common stock issued as consideration for advisory services related to the transaction.

Dividends

From and after the issue date of the Redeemable Convertible Preferred Stock, cumulative dividends accrue on the Accrued Value (as defined below) of each share of Redeemable Convertible Preferred Stock at the annual rate of 8%. Dividends on each share of Redeemable Convertible Preferred Stock are cumulative and accrue daily from and after the issue date, but compound on a quarterly basis on the last day of each calendar quarter (the “Quarterly Dividend Date”), whether or not earned or declared, and whether or not there are earnings or profits, surplus or other funds or assets of the Company legally available for the payment of dividends. All such dividends compound and shall be added to the Accrued Value on each Quarterly Dividend Date. No dividends are to be paid in cash unless such dividends are paid pursuant to liquidation of the Company or a conversion or redemption of the Redeemable Convertible Preferred Stock.

In the event that the board of directors declares a dividend payable upon the then outstanding shares of common stock (other than a stock dividend on the common stock payable solely in the form of additional shares of common stock), the holders of the Redeemable Convertible Preferred Stock shall be entitled, in addition to any cumulative dividends to which the Redeemable Convertible Preferred Stock may be entitled, to receive (concurrent with the payment of the dividend to the holders of common stock) the amount of dividends per share of Redeemable Convertible Preferred Stock that would be payable on the number of whole shares of the common stock into which each share of such Redeemable Convertible Preferred Stock held by each holder could be converted, such number to be determined as of the record date for the determination of holders of common stock entitled to receive such dividend.

“Accrued Value” means, with respect to each share of Redeemable Convertible Preferred Stock, the sum, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Redeemable Convertible Preferred Stock, of (i) $100.00 plus (ii) on each Quarterly Dividend Date, an additional amount equal to the dollar value of any dividends on a share of Redeemable Convertible Preferred Stock which have accrued on any dividend payment date and have not been previously added to such Accrued Value.

As of June 30, 2024, no dividends have been declared or distributed to any stockholders, and the Company has accrued dividends through June 30, 2024 totaling $2.5 million.

Liquidation Preferences

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company (each, a Liquidation Event) or Deemed Liquidation Event (as defined below), the holders of shares of Redeemable Convertible Preferred Stock shall be entitled to be paid, with respect to each share of Redeemable Convertible Preferred Stock then outstanding held by the holder, out of the assets of the Company available for distribution to its stockholders, on a preferred basis prior and in preference to any distribution to the holders of any common stock or any other junior stock of the Company, an amount in cash per share of Redeemable Convertible Preferred Stock equal to (i) in the event of a Deemed Liquidation Event occurring prior to the 24-month anniversary of the issue date, the greater of (x) 200% multiplied by the sum of the Accrued Value plus an amount equal to all accrued or declared and unpaid

dividends on the Redeemable Convertible Preferred Stock that have not previously been added to the Accrued Value or (y) such amount per share as would have been payable in respect of the shares of common stock into which such share of Redeemable Convertible Preferred Stock is then convertible, assuming all outstanding shares of Redeemable Convertible Preferred Stock were converted into common stock immediately prior to such Deemed Liquidation Event or (ii) in the event of (A) a Liquidation Event that is not a Deemed Liquidation Event or (B) a Deemed Liquidation Event occurring on or after the 24-month anniversary of the issue date, the greater of (x) the sum of the Accrued Value plus an amount equal to all accrued or declared and unpaid dividends on the Redeemable Convertible Preferred Stock that have not previously been added to the Accrued Value or (y) such amount per share as would have been payable in respect of the shares of common stock into which such share of Redeemable Convertible Preferred Stock is then convertible, assuming all outstanding shares of Redeemable Convertible Preferred Stock were converted into common stock immediately prior to such Liquidation Event or Deemed Liquidation Event, as applicable (the Liquidation Amount). Deemed Liquidation Event means a reorganization, merger or consolidation in which: (A) the Company is a constituent party or (B) a subsidiary of the Company is a constituent party and the Company issues shares of its capital stock pursuant to such reorganization, merger or consolidation, except any such reorganization, merger or consolidation involving the Company or a subsidiary in which the shares of capital stock of the Company outstanding immediately prior to such reorganization, merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such reorganization, merger or consolidation, a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation or (2) if the surviving or resulting corporation is a wholly-owned subsidiary of another corporation immediately following such reorganization, merger or consolidation, the parent corporation of such surviving or resulting corporation.

Rights and Preferences

At any time when shares of Redeemable Convertible Preferred Stock are outstanding, the Company shall not, either directly or indirectly (including through any subsidiary of the Company) by amendment, merger, consolidation, reclassification, reorganization or otherwise, do any of the following without (in addition to any other vote required by law or the Company’s Certificate of Incorporation) the written consent or affirmative vote of the holders of a majority of the then outstanding shares of Redeemable Convertible Preferred Stock (or, solely with respect to section (a) below, the holders of 75% of the then outstanding shares of Redeemable Convertible Preferred Stock), given in writing or by vote at a meeting, consenting or voting separately as a class, and any such act taken or transaction entered into without such consent or vote shall be null and void, and of no force or effect:

(a) amend, modify or fail to give effect to the rights of the holders of Redeemable Convertible Preferred Stock;

(b) increase or decrease the number of authorized shares of Redeemable Convertible Preferred Stock;

(c) create or issue any equity securities or securities convertible into equity securities with equal or superior rights, preferences or privileges to those of the Redeemable Convertible Preferred Stock in respect of (i) payment of dividends, or (ii) distribution of assets of the Company upon a Liquidation Event or Deemed Liquidation Event;

(d) other than the issuance of shares of common stock on exercise or conversion of securities outstanding on the issue date, issue any shares of common stock or securities convertible into or exercisable (directly or indirectly) for common stock if at such time (or after giving effect to such issuance) the Company does not have sufficient shares of common stock available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Redeemable Convertible Preferred Stock into common stock (assuming that accrued and unpaid dividends at such time include all dividends that would have accrued on the Redeemable Convertible Preferred Stock for a period of five years from the date thereof) and the exercise and conversion of all other securities convertible or exercisable (directly or indirectly) for common stock;

(e) declare or pay any dividends or distributions on or make redemptions or repurchases of equity securities, except for repurchases from employees, directors, advisors or consultants upon termination pursuant to contractual call rights; or

(f) create any subsidiary that is not majority-owned, either directly or indirectly, by the Company; provided, however, that this restriction shall not apply, in the case of (i) any subsidiary created outside of the United States, solely to the extent that, due to local law or regulatory requirements, the Company is not permitted to legally own such subsidiary or (ii) the creation of any joint venture created in the ordinary course of business for a bona fide business purpose.

Registration Rights

Voting

The holder of each share of Redeemable Convertible Preferred Stock is entitled to one vote for each share of common stock into which such Redeemable Convertible Preferred Stock is convertible on the record date for determining stockholders entitled to vote on such matter. With respect to such vote, such holder has full voting rights and powers equal to the voting rights of the holders of common stock.

Conversion

Each share of Redeemable Convertible Preferred Stock is convertible, at the option of the holder, at any time and from time to time, into such number of shares of common stock as is determined by dividing the Accrued Value by the Conversion Price (defined below) in effect at the time of conversion. The Conversion Price is initially equal to $42.5394 per share. If at any time following the third anniversary of the issue date, the closing sale price of the Company’s common stock exceeds 250% of the Conversion Price for 30 consecutive trading days, then the Company has the right to require conversion of the Redeemable Convertible Preferred Stock, in whole or in part, at the then effective conversion rate.

Redemption

On or after the seventh anniversary of the issue date, (i) each holder of Redeemable Convertible Preferred Stock may require the Company to redeem all of such holder’s shares of Redeemable Convertible Preferred Stock for cash at a redemption price per share equal to the Accrued Value, and (ii) the Company may redeem, in whole or in part on a pro rata basis from all holders, shares of Redeemable Convertible Preferred Stock for cash at a redemption price per share equal to the Accrued Value.

The Company has classified the Redeemable Convertible Preferred Stock as temporary equity as the shares have certain redemption features that are not solely in the control of the Company. The Redeemable Convertible Preferred Stock is not currently redeemable because the deemed liquidation provision is considered a substantive condition that is contingent on the event and it is not currently probable that it will become redeemable. The Redeemable Convertible Preferred Stock is not currently redeemable through the optional redemption provision because it is considered a substantive condition that is contingent on the passage of time.

The Company classifies Redeemable Convertible Preferred Stock in accordance with ASC 480, Distinguishing Liabilities from Equity, which requires that contingently redeemable securities be classified outside of permanent stockholders’ (deficit) equity.

Accordingly, the Company has classified all shares of Redeemable Convertible Preferred Stock as mezzanine equity in the accompanying financial statements as of June 30, 2024 and December 31, 2023.
