The Company may need to obtain additional financing to complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. Until such time, if ever, the Company can generate revenue sufficient to achieve profitability, the Company expects to finance its operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. There can be no assurance that such financing will be available on terms acceptable to the Company, or at all. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the ownership interest of its stockholders will be diluted, and the terms of these securities may include liquidation of other preferences that adversely affect the rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting the Company&#8217;s ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If the Company is unable to maintain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. The Company may be required to delay, limit, reduce or terminate its product discovery and development activities or future commercialization efforts. </div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"><div style="display:inline;">The Company initiated a Phase 1 clinical trial of ACU193 in 2021, which the Company named &#8220;INTERCEPT-AD.&#8221; In October 2021, the Company announced the initial dosing of the first patient in the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">INTERCEPT-AD</div> trial and the subsequent successful sentinel safety review of the first two patients.

In calculating right-of-use assets and lease liabilities, the Company has elected to combine lease and non-lease components. Additionally, the Company has elected to apply the practical expedient related to short-term leases (i.e., leases having initial terms of 12&#160;months or less at commencement date) as an accounting policy election. For short-term leases, the Company will not recognize a right-of-use asset or lease liability, but instead will recognize lease payments as an expense on a straight-line basis over the lease term. </div></div></div> </ix:continuation> <div style="letter-spacing: 0px; top: 0px; background: none;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; background: none; text-decoration: none;;display:inline;"> </div></div></ix:nonNumeric> <div style="margin-top: 0px; margin-bottom: 0px; font-size: 8pt;">&#160;</div> <div style="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman;text-align:center">6 </div> </div> </div> <div style="margin-top:1em; margin-bottom:0em; page-break-before:always"></div> <hr style="color:#999999;height:3px;width:100%"/> <div style="font-size: .83em;margin-top : 1.67em;margin-bottom : 1.67em;font-weight: bold;"><a href="#toc">Table of Contents</a></div> </div> </div> <div><div style="background-color:white;display: inline;"><div style="text-align:center"><div style="width:8.5in;text-align:left;margin-left: auto;margin-right: auto"><div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &quot;Times New Roman&quot;; text-align: center;"><div style="font-weight:bold;display:inline;">Acumen Pharmaceuticals, Inc. </div></div><div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &quot;Times New Roman&quot;; text-align: center;"><div style="font-weight:bold;display:inline;">Notes to Condensed Financial Statements </div></div><div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &quot;Times New Roman&quot;; text-align: center;"><div style="font-weight:bold;display:inline;">(Unaudited) </div></div><div style="margin-top: 0px; margin-bottom: 0px; font-size: 8pt;">&#160;</div><ix:continuation id="TextSelection_47664782"> <ix:nonNumeric name="abos:RecentlyAdoptedAccountingProuncementsPolicyTextBlock" contextRef="P01_01_2022To03_31_2022" escape="true"><div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &quot;Times New Roman&quot;;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Recently Adopted Accounting Pronouncements </div></div></div></div> <div style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">ASC 842 requires lessees to recognize the liabilities related to all leases, including operating leases, with a term greater than 12 months on the balance sheet and also requires lessees and lessors to disclose key information about their leasing transactions.

ASC 326 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The updated guidance is effective for the Company for annual reporting periods beginning after December&#160;15, 2022, and early adoption is permitted.

The Company became publicly traded in July 2021 and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected term of the Company&#8217;s stock options has been determined using the &#8220;simplified&#8221; method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. </div> <ix:nonNumeric name="us-gaap:DisclosureOfShareBasedCompensationArrangementsByShareBasedPaymentAwardTextBlock" contextRef="P01_01_2022To03_31_2022" escape="true"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The following table reflects summarized stock option activity: </div></div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div></div>

Alzheimer&#8217;s disease is a progressive neurodegenerative disease of the brain that leads to loss of memory and cognitive functions and ultimately results in death. Our scientific founders pioneered research on soluble amyloid-beta oligomers, or A&#946;Os, which are globular assemblies of the A&#223; peptide that are distinct from A&#223; monomers and amyloid plaques. We are currently focused on advancing a targeted immunotherapy drug candidate, ACU193, through clinical proof of mechanism trials in early AD patients. We initiated a Phase 1 clinical trial of ACU193 in 2021, which we named <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">&#8220;INTERCEPT-AD.&#8221;</div> This trial is enrolling patients with mild dementia or mild cognitive impairment due to AD, conditions referred to as &#8220;early AD.&#8221; <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">INTERCEPT-AD</div> is a U.S.-based, multi-center, randomized, double-blind, placebo-controlled clinical trial with overlapping single ascending dose, or SAD, and multiple ascending dose, or MAD, cohorts involving a total of approximately 62 patients with early AD. The overall objective of the trial is to evaluate the safety and tolerability and establish clinical proof of mechanism of ACU193 administered intravenously. The primary trial endpoints are focused on safety and immunogenicity. An important safety measure will be the use of magnetic resonance imaging, or MRI, to assess the presence or absence of amyloid-related imaging abnormalities. Secondary endpoints include pharmacokinetics in plasma and cerebrospinal fluid, or CSF, and target engagement as evidenced by detection of ACU193 bound to A&#223;Os in CSF. Clinical scales typically used in AD trials as well as computerized cognitive testing are included as exploratory measures. In October 2021, we announced the initial dosing of the first patient in the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">INTERCEPT-AD</div> trial and the subsequent successful sentinel safety review of the first two patients. Due to delays in clinical trial site activation and patient enrollment that we believe are principally related to the effects of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic, we are expanding the anticipated number of trial sites to support our enrollment objectives and anticipated timelines. Clinical trial site activation and patient recruitment and enrollment is ongoing. Based on current site activations and enrollment rates, we anticipate reporting our topline data from the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">INTERCEPT-AD</div> trial in the first half of 2023. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We have incurred net losses and negative cash flows from operations since our inception. Our net losses were $9.1&#160;million and $27.0&#160;million for the three months ended March&#160;31, 2022 and 2021, respectively. As of March&#160;31, 2022, we had an accumulated deficit of $136.7&#160;million. Our net losses and cash flows from operations may fluctuate significantly from <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">quarter-to-quarter</div></div> and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">year-to-year,</div></div> depending on the timing of nonclinical studies, clinical trials and our expenditures on other research and development activities. We expect our expenses and operating losses will increase substantially for the foreseeable future as we advance ACU193 in clinical trials, seek to expand our product candidate portfolio through developing additional product candidates, grow our clinical, regulatory and quality capabilities, and incur additional costs associated with operating as a public company. It is likely that we will seek third-party collaborators for the future commercialization of ACU193 or any other product candidate that is approved for marketing. However, we may seek to commercialize our products at our own expense, which would require us to incur significant additional expenses for marketing, sales, manufacturing and distribution. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. In addition, if we obtain regulatory approval for our product candidates and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, manufacturing and distribution activities. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">14 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings and debt financings or other sources, such as potential collaboration agreements, strategic alliances and licensing arrangements. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our failure to raise capital or enter into such agreements as, and when needed, could have a material adverse effect on our business, results of operations and financial condition. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As of March&#160;31, 2022, we had cash, cash equivalents and marketable securities totaling $216.7&#160;million. Based on our current operating plan, we expect that our existing cash and cash equivalents and marketable securities will be sufficient to enable us to fund our operating expenses and capital expenditure requirements at least through 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.

Furthermore, we have and expect to incur additional costs associated with operating as a public company following our July 2021 IPO. It is likely that we will seek third-party collaborators for the future commercialization of ACU193 or any other product candidate that is approved for marketing. However, we may seek to commercialize our products at our own expense, which would require us to incur significant additional expenses for marketing, sales, manufacturing and distribution, which costs we may seek to offset through entry into collaboration agreements with third parties. As a result, we expect that we will need to obtain substantial additional funding in connection with our future operations. If we are unable to raise capital when needed or on acceptable terms, we could be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">18 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;;font-weight: bold;"><a href="#toc" style="text-indent: 0px;">Table of Contents</a></div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Based on our current operating plan, we expect that our existing cash and cash equivalents and our marketable securities will be sufficient to enable us to fund our operating expenses and capital expenditure requirements at least through 2025.

Section&#160;107 of the JOBS Act provides that an &#8220;emerging growth company&#8221; can take advantage of the extended transition period provided in Section&#160;7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards.

As of March&#160;31, 2022 and December&#160;31, 2021, the Company had an accumulated deficit of $136.7&#160;million and $127.6&#160;million, respectively, and working capital of $188.1&#160;million and $193.5&#160;million, respectively. Management believes that its existing financial resources are sufficient to continue operating activities at least through 2025. </div> <div style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Future capital requirements will depend upon many factors, including the timing and extent of spending on research and development and market acceptance of the Company&#8217;s products. The Company may need to obtain additional financing to complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. Until such time, if ever, the Company can generate revenue sufficient to achieve profitability, the Company expects to finance its operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. There can be no assurance that such financing will be available on terms acceptable to the Company, or at all. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the ownership interest of its stockholders will be diluted, and the terms of these securities may include liquidation of other preferences that adversely affect the rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting the Company&#8217;s ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If the Company is unable to maintain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. The Company may be required to delay, limit, reduce or terminate its product discovery and development activities or future commercialization efforts. </div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"/> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"><div style="display:inline;">The Company initiated a Phase 1 clinical trial of ACU193 in 2021, which the Company named &#8220;INTERCEPT-AD.&#8221; In October 2021, the Company announced the initial dosing of the first patient in the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">INTERCEPT-AD</div> trial and the subsequent successful sentinel safety review of the first two patients. Due to delays in clinical trial site activation and patient enrollment that the Company believes are principally related to effects of the coronavirus <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(&#8220;COVID-19&#8221;)</div> pandemic, the Company is expanding the anticipated number of trial sites to support its enrollment objectives and anticipated timelines. Clinical trial site activation and patient recruitment and enrollment is ongoing. Based on current site activations and enrollment rates, the Company anticipates reporting its topline data from this trial in the first half of 2023. The ultimate impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic on the Company&#8217;s business, results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak and related advisories and restrictions. These developments and the impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic, and the ongoing military conflict between Russia and Ukraine and related sanctions against Russia, on the financial markets and the overall economy are highly uncertain and cannot be predicted. If the financial markets and/or the overall economy are impacted for an extended period, the Company&#8217;s results of operations, financial position and cash flows may be materially adversely affected. </div></div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"> </div><span></span>

Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the condensed consolidated balance sheet as both a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">right-of-use</div></div> asset and a lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company&#8217;s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">right-of-use</div></div> assets are amortized over the lease term.

In calculating right-of-use assets and lease liabilities, the Company has elected to combine lease and non-lease components. Additionally, the Company has elected to apply the practical expedient related to short-term leases (i.e., leases having initial terms of 12&#160;months or less at commencement date) as an accounting policy election. For short-term leases, the Company will not recognize a right-of-use asset or lease liability, but instead will recognize lease payments as an expense on a straight-line basis over the lease term. </div></div></div>  <div style="letter-spacing: 0px; top: 0px; background: none;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; background: none; text-decoration: none;;display:inline;"> </div></div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &quot;Times New Roman&quot;;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Recently Adopted Accounting Pronouncements </div></div></div></div> <div style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">ASC 842 requires lessees to recognize the liabilities related to all leases, including operating leases, with a term greater than 12 months on the balance sheet and also requires lessees and lessors to disclose key information about their leasing transactions. The Company adopted&#160;this guidance on January&#160;1, 2022, using the modified retrospective method and the Company elected the package of practical expedients upon transition, which retained the lease classification for leases that existed prior to the adoption of this guidance. The Company recorded both a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">right-of-use</div></div> asset and a lease liability of approximately $0.2&#160;million on its condensed balance sheet upon the adoption of ASC 842. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">In December 2019, the FASB issued ASU <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">No.&#160;2019-12,</div> <div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes </div></div>(&#8220;ASU <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">2019-12&#8221;),</div> which is intended to simplify various aspects related to accounting for income taxes. ASU <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">2019-12</div> removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application.

ASC 326 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The updated guidance is effective for the Company for annual reporting periods beginning after December&#160;15, 2022, and early adoption is permitted. The Company&#8217;s marketable securities portfolio consists entirely of debt securities and, as such, it does not expect this guidance to have a material impact on its financial statements and disclosures upon adoption. </div></div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"> </div> <span></span>

The 2021 Plan is a successor to the Company&#8217;s Amended and Restated Stock Performance Plan that was adopted by the Board and stockholders on April 8, 2013 (as amended from time to time, most recently on November 20, 2020, the &#8220;2013 Plan&#8221;).

The Company became publicly traded in July 2021 and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected term of the Company&#8217;s stock options has been determined using the &#8220;simplified&#8221; method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The following table reflects summarized stock option activity: </div></div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div></div>

In calculating right-of-use assets and lease liabilities, the Company has elected to combine lease and non-lease components. Additionally, the Company has elected to apply the practical expedient related to short-term leases (i.e., leases having initial terms of 12&#160;months or less at commencement date) as an accounting policy election. For short-term leases, the Company will not recognize a right-of-use asset or lease liability, but instead will recognize lease payments as an expense on a straight-line basis over the lease term. </div></div></div> <span></span>

ASC 326 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The updated guidance is effective for the Company for annual reporting periods beginning after December&#160;15, 2022, and early adoption is permitted. The Company&#8217;s marketable securities portfolio consists entirely of debt securities and, as such, it does not expect this guidance to have a material impact on its financial statements and disclosures upon adoption. </div></div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"> </div><span></span>

The par value and the number of authorized shares of the convertible preferred stock and common stock were not adjusted in connection with the June 2021 Reverse Stock Split. All references to common stock, convertible preferred stock, warrants to purchase common stock, warrants to purchase convertible preferred stock, options to purchase common stock, share data, per share data and related information contained in the financial statements have been retrospectively adjusted to reflect the effect of the June 2021 Reverse Stock Split for all periods presented. No fractional shares of the Company&#x2019;s common stock were issued in connection with the June 2021 Reverse Stock Split.

The price to the public for each share was $16.00. The aggregate net proceeds from the Company&#x2019;s IPO, after underwriting discounts and commissions and other offering expenses of $15.4&#160;million, were $168.6&#160;million. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On July 6, 2021, in connection with the closing of the IPO, 477,297 shares of Series&#160;A, 7,985,305 shares of Series&#160;A-1, and 19,770,070 shares of Series&#160;B convertible preferred stock, respectively, automatically converted into an equal number of shares of common stock. Warrants to purchase shares of common stock were automatically net exercised for the purchase of an aggregate of 178,847 shares of common stock. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;As a result of the IPO, the underwriters&#x2019; exercise of their option, the conversions of the Series&#160;A, A-1 and B convertible preferred stock, and the exercise of the warrants, the Company&#x2019;s total number of outstanding common shares increased by 39,911,517 immediately following the closing of the IPO. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Liquidity and Capital Resources &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;br/&gt;&lt;/div&gt; &lt;div style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;The Company has incurred operating losses since inception and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. As of March&#160;31, 2022 and December&#160;31, 2021, the Company had an accumulated deficit of $136.7&#160;million and $127.6&#160;million, respectively, and working capital of $188.1&#160;million and $193.5&#160;million, respectively. Management believes that its existing financial resources are sufficient to continue operating activities at least through 2025. &lt;/div&gt; &lt;div style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;Future capital requirements will depend upon many factors, including the timing and extent of spending on research and development and market acceptance of the Company&#x2019;s products. The Company may need to obtain additional financing to complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. Until such time, if ever, the Company can generate revenue sufficient to achieve profitability, the Company expects to finance its operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. There can be no assurance that such financing will be available on terms acceptable to the Company, or at all. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the ownership interest of its stockholders will be diluted, and the terms of these securities may include liquidation of other preferences that adversely affect the rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting the Company&#x2019;s ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If the Company is unable to maintain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. The Company may be required to delay, limit, reduce or terminate its product discovery and development activities or future commercialization efforts. &lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="display:inline;"&gt;The Company initiated a Phase 1 clinical trial of ACU193 in 2021, which the Company named &#x201c;INTERCEPT-AD.&#x201d; In October 2021, the Company announced the initial dosing of the first patient in the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;INTERCEPT-AD&lt;/div&gt; trial and the subsequent successful sentinel safety review of the first two patients. Due to delays in clinical trial site activation and patient enrollment that the Company believes are principally related to effects of the coronavirus &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;(&#x201c;COVID-19&#x201d;)&lt;/div&gt; pandemic, the Company is expanding the anticipated number of trial sites to support its enrollment objectives and anticipated timelines. Clinical trial site activation and patient recruitment and enrollment is ongoing. Based on current site activations and enrollment rates, the Company anticipates reporting its topline data from this trial in the first half of 2023. The ultimate impact of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;COVID-19&lt;/div&gt; pandemic on the Company&#x2019;s business, results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak and related advisories and restrictions. These developments and the impact of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;COVID-19&lt;/div&gt; pandemic, and the ongoing military conflict between Russia and Ukraine and related sanctions against Russia, on the financial markets and the overall economy are highly uncertain and cannot be predicted. If the financial markets and/or the overall economy are impacted for an extended period, the Company&#x2019;s results of operations, financial position and cash flows may be materially adversely affected. &lt;/div&gt;&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt;</us-gaap:NatureOfOperations>

Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the condensed consolidated balance sheet as both a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; asset and a lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company&#x2019;s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; assets are amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; asset results in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred and not included in the measurement of &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; assets and lease liabilities. &lt;/div&gt;&lt;/div&gt;  &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC 842 provides practical expedients for an entity&#x2019;s ongoing accounting. In calculating right-of-use assets and lease liabilities, the Company has elected to combine lease and non-lease components. Additionally, the Company has elected to apply the practical expedient related to short-term leases (i.e., leases having initial terms of 12&#160;months or less at commencement date) as an accounting policy election. For short-term leases, the Company will not recognize a right-of-use asset or lease liability, but instead will recognize lease payments as an expense on a straight-line basis over the lease term. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style="letter-spacing: 0px; top: 0px; background: none;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; background: none; text-decoration: none;;display:inline;"&gt; &lt;/div&gt;&lt;/div&gt; &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: &amp;quot;Times New Roman&amp;quot;;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Recently Adopted Accounting Pronouncements &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;ASC 842 requires lessees to recognize the liabilities related to all leases, including operating leases, with a term greater than 12 months on the balance sheet and also requires lessees and lessors to disclose key information about their leasing transactions. The Company adopted&#160;this guidance on January&#160;1, 2022, using the modified retrospective method and the Company elected the package of practical expedients upon transition, which retained the lease classification for leases that existed prior to the adoption of this guidance. The Company recorded both a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; asset and a lease liability of approximately $0.2&#160;million on its condensed balance sheet upon the adoption of ASC 842. &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;In December 2019, the FASB issued ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;No.&#160;2019-12,&lt;/div&gt; &lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes &lt;/div&gt;&lt;/div&gt;(&#x201c;ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2019-12&#x201d;),&lt;/div&gt; which is intended to simplify various aspects related to accounting for income taxes. ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2019-12&lt;/div&gt; removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted this guidance on January&#160;1, 2022 with no material impact to the Company&#x2019;s financial statements upon adoption. &lt;/div&gt;&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Recently Issued Accounting Pronouncements &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;In June 2016, the FASB issued &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASU&#160;2016-13,&lt;/div&gt; &lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments&lt;/div&gt;&lt;/div&gt;, which was codified with its subsequent amendments as ASC 326. ASC 326 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The updated guidance is effective for the Company for annual reporting periods beginning after December&#160;15, 2022, and early adoption is permitted. The Company&#x2019;s marketable securities portfolio consists entirely of debt securities and, as such, it does not expect this guidance to have a material impact on its financial statements and disclosures upon adoption. &lt;/div&gt;&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; </us-gaap:SignificantAccountingPoliciesTextBlock>

The Company recorded both a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;right-of-use&lt;/div&gt;&lt;/div&gt; asset and a lease liability of approximately $0.2&#160;million on its condensed balance sheet upon the adoption of ASC 842. &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;In December 2019, the FASB issued ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;No.&#160;2019-12,&lt;/div&gt; &lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes &lt;/div&gt;&lt;/div&gt;(&#x201c;ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2019-12&#x201d;),&lt;/div&gt; which is intended to simplify various aspects related to accounting for income taxes.

ASC 326 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The updated guidance is effective for the Company for annual reporting periods beginning after December&#160;15, 2022, and early adoption is permitted. The Company&#x2019;s marketable securities portfolio consists entirely of debt securities and, as such, it does not expect this guidance to have a material impact on its financial statements and disclosures upon adoption. &lt;/div&gt;&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Unrealized losses on &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;available-for-sale&lt;/div&gt;&lt;/div&gt; securities as of&#160;March 31, 2022 were not&#160;significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Accordingly, no other-than-temporary impairment was recorded for the three months ended&#160;March 31, 2022.&#160;The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity. &lt;/div&gt;</abos:DisclosureOfMarketableSecuritiesTextBlock>

For the year ended December&#160;31, 2020, management engaged an independent third-party valuation firm to provide an estimate of the fair value of its common stock, which was utilized as an input to the Company&#x2019;s Black-Scholes option pricing model for stock options awarded during the three months ended March&#160;31, 2021. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px; background: none;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; background: none; text-decoration: none;;display:inline;"&gt; &lt;/div&gt;&lt;/div&gt; &lt;div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: &amp;quot;Times New Roman&amp;quot;; text-indent: 0px;"&gt;Stock options granted after December&#160;31, 2017 vest monthly over&lt;div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;a range of&lt;/div&gt;&#160;12 &lt;div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;to&lt;/div&gt; 36 months &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;or vest monthly over a total of 48 months following a one-year cliff&#160;&lt;/div&gt;and &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;all&#160;&lt;/div&gt;have a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;"&gt;ten-year&lt;/div&gt; contractual term. Stock options granted prior to December&#160;31, 2017 were either fully vested upon grant or generally vested monthly over a range of &lt;span style="-sec-ix-hidden:hidden47664846"&gt;three&lt;/span&gt; to 24 months and have a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;"&gt;ten-year&lt;/div&gt; term. The Company became publicly traded in July 2021 and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected term of the Company&#x2019;s stock options has been determined using the &#x201c;simplified&#x201d; method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The following table reflects summarized stock option activity: &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;
