Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of the fair value hierarchy under FASB ASC 820, Fair Value Measurement, are described as follows:

Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 — Inputs other than quoted prices included in Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data; and

Level 3 — Unobservable inputs that are supported by little or no market activity, which requires the Company to develop its own models.

The financial instruments of the Company consist primarily of cash, money market accounts, receivable, and accounts payable. These items are considered Level 1 due to their short-term nature and their market interest rates and are therefore considered a reasonable estimate of fair value at June 30, 2023 and December 31, 2022. The Company classifies short-term investments within Level 1 in the fair value hierarchy, because quoted prices for identical assets in active markets are used to determine fair value. The Company estimates the fair value of the investment in debt securities using Level 3 inputs. See Note 9 for description of methodologies and significant assumptions used in those valuations. The Company also invested in non-convertible promissory note, prepayment for inventory and equity securities of two privately held companies, which were recorded on cost basis. See Note 7, 9 and 10 to the financial statements for more information.

Treasury bills were purchased on May 12, 2023 and June 23, 2023, at a cost of $10,154 and $2,077, respectively, and fair values accrete to maturity dates at an interest rate of 5.02% and 5.14%, resepectively. As of June 30, 2023, the interest income recorded on these bills was $99.

The Company's privately held debt securities are recorded at fair value on a recurring basis. The estimation of fair value for these investments requires the use of significant unobservable inputs, and as a result, the Company deems these assets as Level 3 within the fair value measurement framework. For investments without a readily determinable fair value, the Company applies valuation methods based on information available, including the market approach and bond plus call pricing approach. Observable transactions, such as the issuance of new equity by an investee and changes in market yield, are indicators of investee enterprise value and are used to estimate the fair value of the Company’s investments.

The Company valued the debt security issued by Monarch Medical Technology LLC (“Monarch”) using a bond plus call option model reflecting the cash flow from the Monarch debt security and assuming a 20% probability of an equity financing, a 20% probability of a change of control, and a 60% probability of payment at maturity or an insolvency event. The Company valued the Mellitus debt security using a bond plus call option model reflecting the cash flow from the Mellitus debt securities and assuming a 70% probability of an equity financing, 8% probability of a change of control, and a 22% probability of payment at maturity or an insolvency event. The fair value of the Company’s privately held debt securities were estimated at $3,962 and $3,679 as of June 30, 2023 and December 31, 2022, respectively.

The key inputs for the valuation model are:


		June 30,
		2023
Risk-free rate		4.32% - 5.33%
Cash flow discount rate		25.8% - 26.9%
Expert term in years		0.50- 3.43
Expected volatility		110.0%- 315.0%

The following table reprents changes in the notes held for the investments with significant unobservable inputs (Level 3):


	Convertible Notes
Balance as of December 31, 2022	$	3,679

As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 23, 2023 (the “Annual Report”). In the opinion of management, these financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods shown in this report are not necessarily indicative of the results that may be expected for any future period, including the full year. Credit Losses on Financial Instruments In accordance with Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Toic 326”), the Company periodically reviews the financial assets for credit losses. Financial instruments include cash, cash equivalents, marketable and non-marketable securities, and accounts receivable. In determing the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions. Any credit loss is recorded as a charge to other income, net, not to exceed the amount of the unrealized loss. Unrealized losses other than the credit loss are recognized in accumulated other comprehensive income (“AOCI”). If the Company has an intent to sell, or if it is more likely than not that the Company will be required to sell a debt security in an unrealized loss position before recovery of its amortized cost basis, the Company will write down the security to its fair value and record the corresponding charge as a component of other income, net. Recently Issued Accounting Pronouncements Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Topic 326”). This ASU requires timelier recording of credit losses on loans and other financial instruments held. Instead of reserves based on a current probability analysis, Topic 326 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. All organizations will now use forward-looking information to better inform their credit loss estimates. Topic 326 requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide information about the amounts recorded in the financial statements. In addition, Topic 326 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326 Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to introduce amendments which will affect the recognition and measurement of financial instruments, including derivatives and hedging. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments – Credit Losses (Topic 326); Targeted Transition Relief. The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20 with an option to irrevocably elect the fair value option in Subtopic 825-10, applied on an instrument-by-instrument basis for eligible instruments upon adoption of Topic 326. This standard and related amendments are effective for the Company’s fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In March 2020, FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments. This ASU improves and clarifies various financial instruments topics, including the current expected credit losses standard issued in 2016 (ASU No. 2016-13). The ASU includes seven different issues that describe the areas of improvement and the related amendments to GAAP, intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments have different effective dates. The issues 1-5 are conforming amendments, which are effective upon issuance of this final update. The Company determined that issues 1-5 have no impact on its financials. The amendments related to issue 6 and 7 effect ASU No. 2016-13, Financial instruments – credit losses (Topic 326): measurement of credit losses on financial statements. Effective dates of issue 6 and 7 are the same as the effective date of ASU No. 2016-13. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This ASU improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. For public business entities, this guidance will be effective for fiscal years beginning after December 15, 2022 and for interim periods within those fiscal years. This ASU should be applied prospectively to all business combinations in the year of adoption. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the troubled debt restructuring accounting model in Accounting Standards Codification (“ASC”) 310-40 for creditors that have adopted the guidance on measurement of credit losses in ASU 2016-13. Additionally, the ASU requires the public business entities to disclose current period gross write-offs by year of origination for financing receivables and net investments in leases as part of their vintage disclosures under ASC 326. For entities that have adopted the amendments in ASU 2026-13, the amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For entities that have not yet adopted the amendments in ASU 2016-13, the effective dates are the same as effective dates in ASU 2016-13.

16.Income Taxes

The Company’s income tax provision for the three months ended June 30, 2023 and 2022 was $1,787 and $1,117, resepectively. The Company’s income tax provision for the six months ended June 30, 2023 and 2022 was $3,451 and $1,700, respectively. The income tax provision reflects its estimate of the effective tax rates expected to be applicable for the full year, adjusted for any discrete events that are recorded in the period in which they occurred. The estimates are re-evaluated each quarter based on the estimated tax expense for the full year.

For uncertain tax positions that meet a “more likely than not” threshold, the Company recognizes the benefit of uncertain tax positions in the financial statements. The Company’s practice is to recognize interest and penalties, if any, related to uncertain tax positions in income tax expense in the statements of operations.

The effective tax rate for the three and six months ended June 30, 2023 was 23.31% and 24.13%, compared to 21.52% and 18.62%, in the same period of the prior year. The increase in effective tax rate for the three and six months ended June 30, 2023 was primarily due to lower tax benefits associated with employee stock-based compensation.

The effective tax rate for the three and six months ended June 30, 2023 differed from the U.S. federal statutory rate of 21% primarily due to state income taxes (net of federal benefit) and federal and state research and development (“R&D”) credit benefit. The effective tax rate for the three and six months ended June 30, 2022 differed from the U.S. federal statury rate of 21% primarily due to tax benefits associated with stock-based compensation plans, state income taxes (net of federal benefit), and federal and state R&D credit benefit.

As of June 30, 2023, and December 31, 2022, the Company had $447 and $401, respectively, of unrecognized tax benefits, excluding interest and penalties. The Company’s practice is to recognize interest and penalty expenses related to uncertain tax positions in income tax expense, which was $56 and $30 for the six months ended June 30, 2023 and the year ended December 31, 2022, respectively.

On August 16, 2022, the Creating Helpful Incentives to Produce Semiconductors for America Act of 2022 (“CHIPS and Science Act”), and Inflation Reduction Act (“IRA”) was signed into law in the United States. Among other things, CHIPS and Science Act provides incentives and tax credits for the global chip manufacturers who choose to set-up or expand existing operations in the United States. The IRA imposes a 15% corporate alternative minimum tax for tax years beginning after December 31, 2022, levies a 1% excise tax on net stock repurchases after December 31, 2022, and provides tax incentives to promote clean energy. This act is primarily applicable to large corporations with an annual revenue of $1 billion or over. Implementation of this act has no impact on the Company’s financial statements as of June 30, 2023.

Concentration of Credit Risk

Concentration of Credit Risk

12.Concentration of Credit Risk

Credit risk is the risk of loss from amounts owed by the financial counterparties. Credit risk can occur at multiple levels; as a result of broad economic conditions, challenges within specific sectors of the economy, or from issues affecting individual companies. Financial instruments that potentially subject the Company to credit risk consist of cash and accounts receivable.

The Company maintains cash with major financial institutions. The Company’s cash consists of bank deposits held with banks that, at times, exceed federally insured limits. The cash and cash equivalents also include short-term treasury bills with original maturities of three months or less. As of June 30, 2023, the Company held deposits of $10,620, approximately $5,561 of which held by First Republic Bank (“FRB”). The Company’s deposits at FRB are largely uninsured. On May 1, 2023, JP Morgan Chase Bank (“JPM”) agreed to acquire all the assets and liabilities of FRB. Consequently, all depositors of FRB will become the depositors of JPM. Deposits at JPM are largely uninsured. The Company also invested in U.S. treasury bills in the amount of $41,205 as of June 30, 2023. The Company limits its credit risk by dealing with counterparties that are considered to be of high credit quality and by performing periodic evaluations of the relative credit standing of these financial institutions.

Management periodically monitors the creditworthiness of its customers and believes that it has adequately provided for exposure to potential credit loss. For the three months ended June 30, 2023, two customers (including affiliates) accounted for 37.2% and 33.5% of the Company’s revenues. For the three months ended June 30, 2022, two customers (including affiliates) accounted for 38.1% and 32.3% of the Company’s revenues. For the six months ended June 30, 2023, two customers accounted for 39.0% and 33.5%, of the Company’s revenues, respectively. For the six months ended June 30, 2022, two customers accounted for 38.6% and 32.0%, of the Company’s revenues, respectively. As of June 30, 2023, three customers accounted for 37.5%, 33.3%, and 10.3% of the Company’s accounts receivable. As of December 31, 2022, three customers accounted for 26.8%, 25.9%, and 16.8% of the Company’s accounts receivable. The Company’s largest customer in terms of both revenues and accounts receivable in the three and six months ended June 30, 2023 is a U.S. diversified healthcare company and its affiliated plans.

As of June 30, 2023, five vendors accounted for 14.5%, 11.8%, 11.6%, 10.9% and 10.2% of the Company’s accounts payable. As of December 31, 2022, two vendors accounted for 25.8% and 10.8% of the Company’s accounts payable.

Net Income Per Share, Basic and Diluted

17.Net Income Per Share, Basic and Diluted

Basic earnings per share (“EPS”) represent net income attributable to common stockholders divided by the weighted average number of common shares outstanding during the measurement period. Diluted EPS represents net income attributable to common stockholders divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period using the treasury stock method.

Basic and diluted EPS is calculated as follows:


	Three months ended June 30,
	2023					2022
	Shares	Net Income		EPS		Shares	Net Income		EPS
Basic	6,707,341	$	5,879	$	0.88	6,761,050	$	4,074	$	0.60
Common stock warrants	39,292		—			67,434		—

	Six months ended June 30,

	Shares	Net Income		EPS		Shares	Net Income		EPS
Basic	6,704,306	$	10,848	$	1.62	6,769,552	$	7,434	$	1.10
Common stock warrants	58,083		—			69,637		—

Diluted	7,887,584	$	10,848	$	1.38	8,071,509	$	7,434	$	0.92

As of June 30, 2023, 5,000 options related to stock awards were granted and unvested. These options were considered anti-dilutive for the computation of diluted net income per share. Hence, these options were excluded from the computation of diluted net income per share. As of June 30, 2022, there were no weighted average shares outstanding of common stock equivalents excluded from the computation of diluted net income per share.

Long term investments consist of the following for the periods presented:


	June 30,		December 31,
	2023		2022
Investments in SYNAPS Dx	$	512	$	512
Investments in Mellitus Health Inc.		309		309
Total initial cost	$	821	$	821

In September 2020, the Company acquired a promissory note from NeuroDiagnostics Inc., which is doing business as SYNAPS Dx, in the principal amount of $500, $100 of which was retained for expense reimbursement. Subsequently, in December 2020, the Company agreed to convert the promissory note, together with all accrued interest thereon, into shares of preferred stock of SYNAPS Dx as repayment in full of the promissory note. The value of the note exchanged for the shares of preferred stock of SYNAPS Dx held by the Company as of June 30, 2023 and December 31, 2022 was approximately $512.

In October 2020, the Company acquired from a seller a convertible promissory note previously issued by Mellitus Health Inc. (“Mellitus”) to such seller for a purchase price of $59, which represented the $50 principal amount of the note and all accrued and unpaid interest thereon.

Subsequently, in October 2020, the Company purchased $250 of shares of preferred stock of Mellitus, and in connection with such transaction, the convertible promissory note, together with all accrued interest thereon, also converted pursuant to its terms into shares of preferred stock of Mellitus as repayment in full of such convertible promissory note. The value of consideration exchanged for the shares of preferred stock of Mellitus held by the Company as of June 30, 2023 and December 31, 2022 was approximately $309.

The investments in SYNAPS Dx and Mellitus securities that were retained by the Company as of June 30, 2023 were recorded in accordance with ASC 321, Investments – equity securities, which provides that investments in equity securities in privately-held companies without readily determinable fair values are generally recorded at cost, plus or minus subsequent observable price changes in orderly transactions for identical or similar investments, less impairments. The Company elected the practical expedient permitted by ASC 321 and recorded the above investments on a cost basis. As a part of the assessment for impairment indicators, the Company considers significant deterioration in the earnings performance and overall business prospects of the investee as well as significant adverse changes in the external environment these investments operate. If qualitative assessment indicates the investments are impaired, the fair value of these equity securities would be estimated, which would involve a significant degree of judgement and subjectivity.

The Company qualitatively assessed both investments for impairment in accordance with ASC 321. As of June 30, 2023 and December 31, 2022, the Company determined that there was no impairment for the investment in SYNAPS Dx and the investment in Mellitus.

Senior Secured Convertible Note

In December 2022, the Company committed a loan of $5,000 to Monarch through the purchase of a senior secured convertible promissory note that bears interest at a rate of 10% per annum and matures on the second anniversary from the issue date, which can be extended for up to two additional consecutive one-year terms in the Company’s sole discretion. The note along with up to $100 of transaction expenses is due and payable on the occurrence of an event of default or change of control unless accelerated due to the conversion into preferred stock prior thereto at the option of the Company. Monarch borrowed $3,500 on the issuance date and $500 in the first quarter of 2023 out of the committed amount of $5,000 and has agreed to reimburse the Company for up to $100 of

transaction expense. Repayment of the note is secured by a first priority interest in all of Monarch’s assets. See Note 8 and 9 to the Unaudited Condensed Financial Statements.

Indemnification Obligations

The Company enters into agreements with customers, partners, lenders, consultants, lessors, contractors, sales representatives and parties to certain transactions in the ordinary course of the Company’s business. These agreements may require the Company to indemnify the other party against third party claims alleging that its product infringes a patent or copyright. Certain of these agreements require the Company to indemnify the other party against losses arising from: a breach of representations or covenants, claims relating to property damage, personal injury or acts or omissions of the Company, its employees, agents or representatives. The Company has also agreed to indemnify the directors and certain of the officers and employees in accordance with the by-laws of the Company. These indemnification provisions will vary based upon the nature and terms of the agreements. In many cases, these indemnification provisions do not contain limits on the Company’s liability, and the occurrence of contingent events that will trigger payment under these indemnities is difficult to predict. As a result, the Company cannot estimate its potential liability under these indemnities. The Company believes that the likelihood of conditions arising that would trigger these indemnities is remote and, historically, the Company has not made any significant payment under such indemnification provisions. Accordingly, the Company has not recorded any liabilities relating to these agreements. In certain cases, the Company has recourse against third parties with respect to the aforesaid indemnities, and the Company believes it maintains adequate levels of insurance coverage to protect the Company with respect to potential claims arising from such agreements.

401(K) Plan

Effective January 1, 2022, the Company started to match 50% of employee’s 401(k) deferral up to a maximum of 6% of the employee’s eligible earnings.

Other

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) provides for an employee retention payroll tax credit for certain employers, which is a refundable tax credit against certain employment taxes equal to 50% of the qualified wages an eligible employer pays to employees after March 12, 2020 and before December 31, 2021. For each employee, wages (including health plan costs) up to $10,000 can be counted to determine the amount of the 50% credit. The Company started claiming this credit on its July 2020 payroll until mid-April 2021 when it determined that it no longer qualified given the change in government restrictions on travel that had impacted its sales activities. The Company’s determination that it qualified to claim the employee retention payroll tax credit is subjective and subject to audit by the Internal Revenue Service (“IRS”). If the IRS were to disagree with the Company’s tax position, it could be required to pay the retention credit claimed, along with penalties. As of June 30 2023, the Company has claimed $1.24 million in this retention credit. No credit was claimed for the three and six months ended June 30, 2023 and for the year ended December 31, 2022.

Litigation

From time to time in the normal course of business, the Company is subject to various legal matters, such as threatened or pending claims or litigation. Although the results of claims and litigation cannot be predicted with certainty, the Company does not believe it is a party to any claim or litigation the outcome of which, if determined adversely to it, would individually or in the aggregate be reasonably expected to have a material adverse effect on its results of operations or financial condition.

In June 2022, the Company loaned Mellitus an aggregate of $1,000 through the purchase of two senior secured promissory notes that bear interest at a rate of 5% per annum, and mature in three years unless accelerated due to an event of default as provided in the notes. Repayment of notes is secured by a first priority interest in all of Mellitus’ assets.

In May 2022, to facilitate the subordination of such notes in connection with the purchase of the senior secured notes, the Company acquired $179 aggregate principal amount of outstanding convertible notes of Mellitus, which, as amended, mature July 5, 2025, if not automatically converted into preferred stock prior thereto. This note bears an interest rate of 10% per annum.

In December 2022, the Company entered in a senior convertible promissory note arrangement with Monarch, providing Monarch with up to $5,000 in available funding, of which $4,000, in principal was drawn as of June 30, 2023. The remaining $1,000 is available to be drawn at any time unless there is an event of default (as defined in the note) that is continuing. The Monarch debt security accrues interest at 10% per annum, payable monthly, and the principal balance is due December 6, 2024. The note along with up to $100 of transaction expenses is due and payable on the occurrence of an event of default or change of control unless accelerated due to the conversion into preferred stock prior thereto at the option of the Company. The Company has the option to extend the maturity date for two consecutive one-year terms. The Monarch debt security can be converted into Monarch’s shares at the Company’s option upon (a) an equity financing at Monarch, (b) upon a change of control at Monarch, or (c) at the Company’s option at any time prior to the maturity date. If converted upon a change of control, the Company has the right to receive a cash payment equal to the balance of the Monarch debt security or the amount payable upon conversion into Monarch’s shares. The Monarch debt security is redeemable at any time at Monarch’s option or automatically upon an event of default (as defined in the note).

The Company made an irrevocable election to account for the Mellitus and Monarch debt securities using the fair value option under ASC 825 – Financial Instruments (“ASC 825”) and will measure the fair value of the such debt securities in accordance with ASC 820. The Company made the fair value option election to present the debt securities in their entirety at fair value, which it believes to be preferable to recognizing the host instrument at fair value under ASC 320 and potentially separately recognizing certain embedded features as bifurcated derivatives under ASC 815. As of June 30, 2023, the Company estimated the fair value of the Monarch debt security to be $3,741 and the Mellitus debt security to be $221. As of December 31, 2022, the Company estimated the fair value of the Monarch debt security to be $3,500 and the Mellitus debt security to be $179, which were equivalent of the outstanding principal balances at December 31, 2022.

The Company recognizes interest income as it accrues on the Monarch debt securities, which is included in interest income in the statements of income. For the three months ended June 31, 2023 and 2022, the Company recognized $118 and $3, respectively, of interest income from Monarch and Mellitus notes, which is included in prepaid and other current assets. For the six months ended June 30, 2023 and 2022, the Company recognized $227 and $3, respectively, of interest income from Monarch and Mellitus notes. Unpaid balance is included in prepaid and other current assets. The Company recognizes changes in fair value of the notes in the statements of income separately from the interest income. For the three months ended June 30, 2023, the Company recorded change in fair value of $111. For the six months ended June 30, 2023, the Company recorded change in fair value of $217.

3. Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded at the invoiced amount, net of allowance for credit losses. The allowance for credit losses is based on management’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of this allowance for credit losses by considering historical experience, the age of the accounts receivable balances, the credit quality of the customers, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect customers’ ability to pay to determine whether a specific reserve is appropriate. Accounts receivable deemed uncollectable are charged against the allowance for credit losses when identified.

Stock Incentive Plan

Stock Incentive Plan

15.Stock Incentive Plan

The Company’s stock-based compensation program is designed to attract and retain employees while also aligning employees’ interests with the interests of its stockholders. Stock options have been granted to employees under the stockholder-approved 2007 Key Person Stock Option Plan (“2007 Plan”) and stock options and restricted stock have been granted to employees under the stockholder-approved 2014 Stock Incentive Plan (“2014 Plan”). Stockholder approval of the 2014 Plan became effective in

September 2014. The 2014 Plan originally provided that the aggregate number of shares of common stock that may be issued pursuant to awards granted under the 2014 Plan may not exceed 450,000 shares (the “Share Reserve”), however in October 2015, the stockholders approved a 1,500,000 increase to the Share Reserve. In addition, the Share Reserve automatically increases on January 1st of each year, for a period of not more than 10 years, beginning on January 1st of the year following the year in which the 2014 Plan became effective and ending on (and including) January 1, 2024, in an amount equal to 4% of the total number of shares of common stock outstanding on December 31st of the preceding calendar year. The Company’s board of directors may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of shares of common stock than would otherwise occur. On January 1, 2023, the Share Reserve increased by 267,685. The Share Reserve is currently 3,582,888 shares as of June 30, 2023.

In light of stockholder approval of the 2014 Plan, the Company no longer grants equity awards under the 2007 Plan. As of June 30, 2023, there were no shares available for future stock-based compensation grants under the 2007 Plan and 1,722,453 shares of an aggregate total of 3,582,888 shares were available for future stock-based compensation grants under the 2014 Plan.

Treasury Stock Acquired- Related Party Transaction

On March 14, 2022, the Company’s board of directors authorized a share repurchase program under which it may repurchase up to $20.0 million of its outstanding common stock. Under this program the Company may purchase shares on a discretionary basis from time to time through open market purchases, privately negotiated transactions or other means, including through Rule 10b5-1 trading plans or through the use of other techniques such as accelerated share repurchases. The timing and amount of any transactions will be subject to the discretion of the Company based upon market conditions and other opportunities that it may have for the use or investment of its cash balances. The repurchase program has no expiration date, does not require the purchase of any minimum number of shares and may be suspended, modified or discontinued at any time without prior notice. Since the inception of the program, the Company purchased 148,500 shares at a cost of approximately $4,991 as of June 30, 2023.

On May 17, 2023, the Company acquired outstanding warrants to acquire 76,875 shares of its common stock from its chief executive officer at a cost of $1,949. The warrants were originally issued on June 7, 2012 (16,875 shares) with an exercise price of $4.00 per share and on July 31, 2013 (60,000 shares), with an exercise price of $4.50 per share, were amended in September 2015 and, as amended, had an expiration date of July 31, 2023. The $1,949 aggregate cash purchase price reflects the difference between the aggregate exercise price of the warrants and the aggregate fair market value of the shares of common stock underlying the warrants, based on the closing price of a share of the Company’s common stock on May 16, 2023, the date of the warrant repurchase agreement. Following the warrant repurchase, the warrants were cancelled and are no longer issued and outstanding.

Stock Awards

The Company granted fully vested stock awards of 21,923 shares of common stock to a non-employee member of the board of directors and employees as compensation during the six months ended June 30, 2023. Net shares issued after deducting taxes paid on these grants were 16,902. Fair value of these stock awards on grant date was $798. The Company granted fully vested stock awards of 9,610 shares of common stock to the non-employee members of the board of directors, employees and one non-employee as compensation during the six months ended June 30, 2022. Net shares issued after deducting taxes paid on these grants were 7,900. Fair value of these stock awards on grant date was $673.

Stock Options

Aggregate intrinsic value represents the difference between the closing market value as of June 30, 2023 of the underlying common stock and the exercise price of outstanding, in-the-money options. A summary of the Company’s stock option activity and related information for the three months ended June 30, 2023 is as follows:

As of June 30, 2023, the fair value of unvested stock options was approximately $80. This unrecognized stock-based compensation expense is expected to be recorded over a weighted average period of 2.86 years.

No options were granted during the six months ended June 30, 2023. On May 17, 2022 the Company awarded 5,000 options to an employee as compensation pursuant to the 2014 Plan with an exercise price of $30.48 and Black-Scholes options pricing model value of $22.27. In applying the Black-Scholes options pricing model, following assumptions were used: 1) expected price volatility of 78.6%; risk-free interest rate of 2.884%; weighted average expected life of 7 years; and no dividend yield. 1/4th of these options are vested one year after the grant date and 1/48th for each month thereafter contingent upon the participant’s continued service beginning on the initial vesting date and ending when the Vested Ratio equals 1/1.

The following table represents the stock based compensation for the three and six months ended June 30, 2023 and 2022:

On July 31, 2020, the Company entered into a 61-month lease agreement for office space to use, as necessary, for office administration, lab space and assembly and storage purposes, located in Santa Clara, California. The Company took possession of the leased office space in September 2020, and the lease is effective through September 30, 2025.

As of June 30, 2023, the remaining lease term is two years and three months with no options to renew. The Company recognized facilities lease expenses of $22 and $22 for the three months ended June 30, 2023 and 2022, respectively. The Company recognized facilities lease expenses of $44 and $44 for the six months ended June 30, 2023 and 2022, respectively. The following table summarizes the future minimum rental payments required under operating leases that had initial or remaining non-cancelable lease terms greater than one year as of June 30, 2023:

Lessor Arrangements

The Company enters into contracts with customers for the Company’s QuantaFlo product. The Company has determined these contracts meet the definition of a lease under Topic 842. The lease portfolio primarily consists of operating leases that are short-term in nature (monthly, quarterly or one year, all of which have renewal options). The Company allocates the consideration in a bundled contract with its customers based on relative standalone selling prices of the lease and non-lease components. The Company made an accounting policy election to apply the practical expedient to not separate lease and eligible non-lease components. The lease component is the predominant component and consists of fees charged for use of the equipment over the period of the arrangement. The nature of the eligible non-lease component is primarily software support. The assets associated with these leasing arrangements are separately identified in the Balance Sheet as Assets for Lease and separately disclosed in Note 5 to the Unaudited Condensed Financial Statements.

Basis of Presentation (Policies)	6 Months Ended
Basis of Presentation (Policies)	Jun. 30, 2023
Basis of Presentation
Basis of Presentation	Semler Scientific, Inc., a Delaware corporation (“Semler” or “the Company”), prepared the unaudited interim financial statements included in this report in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 23, 2023 (the “Annual Report”). In the opinion of management, these financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods shown in this report are not necessarily indicative of the results that may be expected for any future period, including the full year.
Credit Losses on Financial Instruments	Credit Losses on Financial Instruments In accordance with Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Toic 326”), the Company periodically reviews the financial assets for credit losses. Financial instruments include cash, cash equivalents, marketable and non-marketable securities, and accounts receivable. In determing the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions. Any credit loss is recorded as a charge to other income, net, not to exceed the amount of the unrealized loss. Unrealized losses other than the credit loss are recognized in accumulated other comprehensive income (“AOCI”). If the Company has an intent to sell, or if it is more likely than not that the Company will be required to sell a debt security in an unrealized loss position before recovery of its amortized cost basis, the Company will write down the security to its fair value and record the corresponding charge as a component of other income, net.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Topic 326”). This ASU requires timelier recording of credit losses on loans and other financial instruments held. Instead of reserves based on a current probability analysis, Topic 326 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. All organizations will now use forward-looking information to better inform their credit loss estimates. Topic 326 requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide information about the amounts recorded in the financial statements. In addition, Topic 326 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326 Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to introduce amendments which will affect the recognition and measurement of financial instruments, including derivatives and hedging. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments – Credit Losses (Topic 326); Targeted Transition Relief. The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20 with an option to irrevocably elect the fair value option in Subtopic 825-10, applied on an instrument-by-instrument basis for eligible instruments upon adoption of Topic 326. This standard and related amendments are effective for the Company’s fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In March 2020, FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments. This ASU improves and clarifies various financial instruments topics, including the current expected credit losses standard issued in 2016 (ASU No. 2016-13). The ASU includes seven different issues that describe the areas of improvement and the related amendments to GAAP, intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments have different effective dates. The issues 1-5 are conforming amendments, which are effective upon issuance of this final update. The Company determined that issues 1-5 have no impact on its financials. The amendments related to issue 6 and 7 effect ASU No. 2016-13, Financial instruments – credit losses (Topic 326): measurement of credit losses on financial statements. Effective dates of issue 6 and 7 are the same as the effective date of ASU No. 2016-13. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This ASU improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. For public business entities, this guidance will be effective for fiscal years beginning after December 15, 2022 and for interim periods within those fiscal years. This ASU should be applied prospectively to all business combinations in the year of adoption. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the troubled debt restructuring accounting model in Accounting Standards Codification (“ASC”) 310-40 for creditors that have adopted the guidance on measurement of credit losses in ASU 2016-13. Additionally, the ASU requires the public business entities to disclose current period gross write-offs by year of origination for financing receivables and net investments in leases as part of their vintage disclosures under ASC 326. For entities that have adopted the amendments in ASU 2026-13, the amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For entities that have not yet adopted the amendments in ASU 2016-13, the effective dates are the same as effective dates in ASU 2016-13. The Company adopted this ASU prospectively effective January 1, 2023 and determined that the adoption of this new accounting standard did not have a material impact on its financial statements.
