Exhibit 99.1

Comments from Chief Executive Officer, Dan Peed: “We are pleased to again deliver value to our shareholders. Our book value per share at September 30th increased to $2.78, and our continuing operations reported a core return on equity of 170.3%, with $14.4 million in third quarter earnings. American Coastal continues to outperform its peers and expectations. Although our personal lines segment experienced a pre-tax loss of $5.5 million, this is a significant improvement quarter-over-quarter, and we continue to take pricing and underwriting actions that improve the outlook of the personal lines segment. Consolidated net income for the third quarter was $10.6 million, including a loss on discontinued operations of $3.8 million, which shows the strength of American Coastal’s earnings power. Our focus on expense reduction and the quality of our book of business has delivered results.”

Exhibit 99.1

Quarterly Financial Results

Net income attributable to the Company for the third quarter of 2023 was $10.6 million, or $0.24 per diluted share, compared to a net loss of $70.9 million, or $1.65 per diluted share, for the third quarter of 2022. Of this income, $14.4 million is attributable to continuing operations for the three months ended September 30, 2023, an increase of $41.8 million from a net loss of $27.4 million for the same period in 2022. Drivers of net income from continuing operations during the third quarter of 2023 included increased gross premiums earned partially offset by increased ceded premiums earned driven by our 2023 quota share agreements, a decrease in our loss and LAE incurred, driven by decreased catastrophe losses, and decreased policy acquisition costs and administrative costs, as described below. This was partially offset by the recognition of losses from discontinued operations of $3.8 million, driven by the deconsolidation of activities related directly to supporting the business conducted by UPC.

The Company's total gross written premium increased by $0.7 million, or 0.7%, to $103.9 million for the third quarter of 2023, from $103.2 million for the third quarter of 2022. This increase was driven primarily by an increase in our commercial premiums written, offset by decreased personal lines premiums written. Both of these changes are driven by our focus on transitioning towards a specialty commercial lines underwriter. The breakdown of the quarter-over-quarter changes in both direct written and assumed premiums by state and gross written premium by line of business are shown in the table below.


($ in thousands)	Three Months Ended September 30,
	2023		2022		Change $		Change %
Direct Written and Assumed Premium by State (1)

Personal property	9,886		26,286		(16,400)		(62.4)
Total gross written premium by line of business	$	103,872	$	103,153	$	719	0.7	%

(1) We are no longer writing in Texas or South Carolina as of May 31, 2022.

(2) Assumed premium written for 2023 primarily included commercial property business assumed from unaffiliated insurers. Assumed premium written for 2022 primarily included personal property business assumed from our former subsidiary, UPC totaling $16,537,000.

Loss and LAE decreased by $39.0 million, or 73.9%, to $13.8 million for the third quarter of 2023, from $52.8 million for the third quarter of 2022. Loss and LAE expense as a percentage of net earned premiums decreased 50.4 points to 24.7% for the third quarter of 2023, compared to 75.1% for the third quarter of 2022. Excluding catastrophe losses and reserve development, the Company's gross underlying loss and LAE ratio for the third quarter of 2023 would have been 6.8%, a decrease of 6.9 points from 13.7% during the third quarter of 2022.

Policy acquisition costs decreased by $10.4 million, or 40.0%, to $15.6 million for the third quarter of 2023, from $26.0 million for the third quarter of 2022, primarily due to an increase in reinsurance commission income, driven by our quota share coverage entered into in the second quarter of 2023 in our commercial lines business. This was partially offset by increases in agent commissions, external management fees and premium taxes, all of which are driven by increased commercial lines written premiums described above.

Operating and underwriting expenses decreased by $324 thousand, or 10.4%, to $2.8 million for the third quarter of 2023, from $3.1 million for the third quarter of 2022, primarily due to decreased investments in technology quarter-over-quarter.

Exhibit 99.1

General and administrative expenses decreased by $9.9 million, or 61.9%, to $6.1 million for the third quarter of 2023, from $16.0 million for the third quarter of 2022, driven by the $10,157,000 impairment of all goodwill attributable to our personal lines operating segment in the third quarter of 2022. There was no similar transaction that occurred in 2023.

Commercial Lines Operating Segment Highlights

Pre-tax earnings attributable to the Company's commercial lines operating segment totaled $25.9 million for the third quarter of 2023 compared to $1.8 million for the third quarter of 2022. This increase can be attributed to a decrease in Loss and LAE incurred of $24.4 million, driven by decreased catastrophe losses quarter-over-quarter. In addition, policy acquisition costs decreased $8.8 million, driven by reinsurance commission income earned during the period.

This decrease in Loss and LAE incurred was partially offset by decreased revenues of $9.2 million quarter-over-quarter, driven by decreased net premiums earned during the period. Operating and underwriting expenses and general and administrative expenses remained relatively flat, with a net decrease of $184 thousand experienced quarter-over-quarter.

Personal Lines Operating Segment Highlights

Pre-tax loss attributable to the Company's personal lines operating segment totaled $5.5 million for the third quarter of 2023 compared to a pre-tax loss of $26.5 million for the third quarter of 2022. Drivers of the quarter-over-quarter decrease in pre-tax loss included: a decrease in administrative costs of $9.5 million, driven by a one-time impairment of goodwill attributable to our personal lines during 2022, a decrease in policy acquisition costs of $1.6 million driven by decreased ceding commission expense, partially offset by increased agent commission and policy administration costs, a decrease in loss and LAE incurred of $14.6 million due to decreased non-catastrophe losses and a decrease in operating expenses of $312 thousand driven by decreased investments in technology and underwriting expenses.

These decreases were partially offset by a $4.8 million decrease in revenues quarter-over-quarter. All of these changes can be attributed to the Company's shift towards becoming a specialty commercial lines underwriter, resulting in reduced writings, exposure, and lower costs associated with the servicing of this business.

Reinsurance Costs as a Percentage of Gross Earned Premium

Reinsurance costs as a percentage of gross earned premium in the third quarter of 2023 and 2022 were as follows:


	2023		2022
Non-at-Risk	(0.4)	%	(0.5)	%
Quota Share	(29.9)	%	(11.7)	%
All Other	(36.0)	%	(37.0)	%
Total Ceding Ratio	(66.3)	%	(49.2)	%

Ceded premiums earned related to the Company's catastrophe program decreased, driven by the need for less coverage for the 2023-2024 treaty year due to the reduction in the Company's geographic footprint and exposure, as well as the utilization of quota share reinsurance coverage for our commercial lines operating segment. The resulting increase in quota share reinsurance coverage increased the Company's ceding ratio overall.

Reinsurance costs as a percentage of gross earned premium in the third quarter of 2023 and 2022 for the Company's personal lines and commercial lines operating segments were as follows:

Investment Portfolio Highlights

The Company's cash, restricted cash and investment holdings decreased from $340.9 million at December 31, 2022 to $286.9 million at September 30, 2023. The Company's cash and investment holdings consist of investments in U.S. government and agency securities, corporate debt and investment grade money market instruments. Fixed maturities represented approximately 98.3% of total investments at September 30, 2023 compared to 91% of total investments at December 31, 2022. The Company's fixed maturity investments had a modified duration of 4.0 years at both September 30, 2023 and December 31, 2022.

Book Value Analysis

Book value per common share increased 166.1% from $(4.21) at December 31, 2022, to $2.78 at September 30, 2023. Underlying book value per common share increased 195.3% from $(3.49) at December 31, 2022 to $3.33 at September 30, 2023. An increase in the Company's retained earnings as the result of net income from both continuing and discontinued operations in the first nine months of 2023 drove the increase in the Company's book value per share. As shown in the table below, removing the effect of AOCI increases the Company's book value per common share, as the Company has experienced unfavorable capital market conditions resulting in an accumulated other comprehensive loss position at September 30, 2023.

Exhibit 99.1

Definitions of Non-GAAP Measures

The Company believes that investors' understanding of ACIC's performance is enhanced by the Company's disclosure of the following non-GAAP measures. The Company's methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Net income (loss) excluding the effects of amortization of intangible assets, income (loss) from discontinued operations, realized gains (losses) and unrealized gains (losses) on equity securities, net of tax (core income (loss)) is a non-GAAP measure that is computed by adding amortization, net of tax, to net income (loss) and subtracting income (loss) from discontinued operations, net of tax, realized gains (losses) on the Company's investment portfolio, net of tax, and unrealized gains (losses) on the Company's equity securities, net of tax, from net income (loss). Amortization expense is related to the amortization of intangible assets acquired, including goodwill, through mergers and, therefore, the expense does not arise through normal operations. Investment portfolio gains (losses) and unrealized equity security gains (losses) vary independent of the Company's operations. The Company believes it is useful for investors to evaluate these components both separately and in the aggregate when reviewing the Company's performance. The most directly comparable GAAP measure is net income (loss). The core income (loss) measure should not be considered a substitute for net income (loss) and does not reflect the overall profitability of the Company's business.

Core return on equity is a non-GAAP ratio calculated using non-GAAP measures. It is calculated by dividing the core income (loss) for the period by the average stockholders’ equity for the trailing twelve months (or one quarter of such average, in the case of quarterly periods). Core income (loss) is an after-tax non-GAAP measure that is calculated by excluding from net income (loss) the effect of income (loss) from discontinued operations, net of tax, non-cash amortization of intangible assets, including goodwill, unrealized gains or losses on the Company's equity security investments and net realized gains or losses on the Company's investment portfolio. In the opinion of the Company’s management, core income (loss), core income (loss) per share and core return on equity are meaningful indicators to investors of the Company's underwriting and operating results, since the excluded items are not necessarily indicative of operating trends. Internally, the Company’s management uses core income (loss), core income (loss) per share and core return on equity to evaluate performance against historical results and establish financial targets on a consolidated basis. The most directly comparable GAAP measure is return on equity. The core return on equity measure should not be considered a substitute for return on equity and does not reflect the overall profitability of the Company's business.

Combined ratio excluding the effects of current year catastrophe losses and prior year reserve development (underlying combined ratio) is a non-GAAP measure, that is computed by subtracting the effect of current year catastrophe losses and prior year development from the combined ratio. The Company believes that this ratio is useful to investors, and it is used by management to highlight the trends in the Company's business that may be obscured by current year catastrophe losses and prior year development. Current year catastrophe losses cause the Company's loss trends to vary significantly between periods as a result of their frequency of occurrence

Exhibit 99.1

and severity and can have a significant impact on the combined ratio. Prior year development is caused by unexpected loss development on historical reserves. The Company believes it is useful for investors to evaluate these components both separately and in the aggregate when reviewing the Company's performance. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered as a substitute for the combined ratio and does not reflect the overall profitability of the Company's business.

Net loss and LAE excluding the effects of current year catastrophe losses and prior year reserve development (underlying loss and LAE) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year reserve development from net loss and LAE. The Company uses underlying loss and LAE figures to analyze the Company's loss trends that may be impacted by current year catastrophe losses and prior year development on the Company's reserves. As discussed previously, these two items can have a significant impact on the Company's loss trends in a given period. The Company believes it is useful for investors to evaluate these components both separately and in the aggregate when reviewing the Company's performance. The most directly comparable GAAP measure is net loss and LAE. The underlying loss and LAE measure should not be considered a substitute for net loss and LAE and does not reflect the overall profitability of the Company's business.

Book value per common share, excluding the impact of accumulated other comprehensive loss (underlying book value per common share), is a non-GAAP measure that is computed by dividing common stockholders' equity after excluding accumulated other comprehensive income (loss), by total common shares outstanding plus dilutive potential common shares outstanding. The Company uses the trend in book value per common share, excluding the impact of accumulated other comprehensive income (loss), in conjunction with book value per common share to identify and analyze the change in net worth attributable to management efforts between periods. The Company believes this non-GAAP measure is useful to investors because it eliminates the effect of interest rates that can fluctuate significantly from period to period and are generally driven by economic and financial factors that are not influenced by management. Book value per common share is the most directly comparable GAAP measure. Book value per common share, excluding the impact of accumulated other comprehensive income (loss), should not be considered a substitute for book value per common share and does not reflect the recorded net worth of the Company's business.

Discontinued Operations

On February 27, 2023, the Florida Department of Financial Services was appointed as receiver of the Company's former subsidiary, United Property & Casualty Insurance Company ("UPC"). As such, prior year financial results have been recast to reflect the activity of UPC and activities related directly to supporting the business conducted by UPC within discontinued operations.

Forward-Looking Statements

Statements made in this press release, or on the conference call identified above, and otherwise, that are not historical facts are “forward-looking statements”. The Company believes these statements are based on reasonable estimates, assumptions and plans. However, if the estimates, assumptions, or plans underlying the forward-looking statements prove inaccurate or if other risks or uncertainties arise, actual results could differ materially from those expressed in, or implied by, the forward-looking statements. These statements are made subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.

Factors that could cause actual results to differ materially may be found in the Company's filings with the U.S. Securities and Exchange Commission, in the “Risk Factors” section in the Company's most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. Forward-looking statements speak only as of the date on which they are made, and, except as required by applicable law, the Company undertakes no obligation to update or revise any forward-looking statements.

Our combined ratio of 68.7% improved over 70 points from 139.3% in the same period last year. • Gross premiums earned of $165.8m grew $27.4m (+20%) y/y due to improving rate adequacy in commercial lines. • Current year net catastrophe losses of $5.8m included $2.5m from Hurricane Idalia and $3.3m of reserve strengthening on prior quarter PCS events that was partially offset by $3.3m of favorable prior year reserve development in the current period. • Stockholders’ equity attributable to ACIC as of September 30, 2023, increased to $120.6m or $2.78 per share and $3.33 per share excluding unrealized losses in accumulated other comprehensive income. • Other Highlights • Our name changed from United Insurance Holdings Corp.
