as of December&nbsp;31, 2022 and 2021, and the related Statement of Changes in Net Assets Available for Benefits for the year ended December&nbsp;31, 2022, and the related notes (collectively referred to as the financial statements). In our opinion,
the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December&nbsp;31, 2022 and 2021, and the changes in net assets available for benefits for the year ended December&nbsp;31,
2022, in conformity with accounting principles generally accepted in the United States of America. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Basis for Opinion </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">These financial statements are the responsibility of the Plan&#146;s management. Our responsibility is to express an opinion on the Plan&#146;s financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We conducted our audits in accordance
with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. </P>

Line 4(i) &#150; Schedule of Assets (Held at End of Year) as of December&nbsp;31, 2022, has been subjected to audit procedures performed in conjunction with the audit of the Plan&#146;s financial statements. The supplemental information is the
responsibility of the Plan&#146;s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing
procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content,
is presented in conformity with the Department of Labor&#146;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all
material respects, in relation to the financial statements as a whole. </P> <P STYLE="font-size:12pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

(&#147;JHRPS&#148;). Other Plan expenses are paid by the participants through the investment management fees charged by each mutual fund. Investment management fees are netted against the earnings of each fund through each fund&#146;s expense ratio.
A portion of the expense ratio is paid to JHRPS to cover Plan administration expenses. If the Plan&#146;s share of those fees exceeds the amount that is required by JHRPS to perform its obligations as record-keeper, the excess fees are returned to
the Plan and are available to pay future Plan expenses. During 2022, the Plan&#146;s share of the fees related to this arrangement amounted to $85,816 and were all used to pay fund expenses. Receipts from JHRPS related to this arrangement are
reflected in interest and dividends on the Statement of Changes in Net Assets Available for Benefits. If the excess fees are not used for additional Plan expenses by the end of the quarter following the calendar year in which they were generated,
JHRPS is directed by Unitil to reallocate the excess fees back to participant accounts on a pro rata basis. If the Plan&#146;s share of those fees is less than the amount that is required to pay for the Plan&#146;s expenses, the expenses that exceed
the revenues returned to the Plan shall be paid by the Company from its general funds. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Effective January&nbsp;1, 2023, Plan administration expenses,

various investment options in any combination of stocks, fixed income securities, mutual funds and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of
risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants&#146; account balances and the
amount reported in the Statements of Net Assets Available for Benefits. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">NOTE D&#151;PLAN TERMINATION </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">To the extent that valuation is based on models or inputs that are less observable or unobservable in the
market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level&nbsp;3. A financial instrument&#146;s level
within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Fair value is a market-based
measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Company&#146;s own assumptions are set to reflect those that market
participants would use in pricing the asset or liability at the measurement date. The Company uses prices and inputs that are current as of the measurement date, including during periods of market dislocation. In periods of market dislocation, the
observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level&nbsp;1 to Level&nbsp;2 or from Level&nbsp;2 to Level&nbsp;3. </P>
