SCHEDULE OF INVESTMENTS continued SEPTEMBER 30, 2019 (UNAUDITED)

* During the current year, all of the underlying investments’ value in theseSub-Funds were held in a side-pocket arrangement. The Fund will not be able to redeem such value from any particular underlying investment until such amount is released from its respective side-pocket arrangement. In the aggregate, approximately 0.01% of the Fund’s net assets are in side-pocket arrangements. The Fund is not able to estimate the timing of receipt of such amounts.

Percentages shown are based on net assets.

Sub-Fund investments arenon-income producing.

At September 30, 2019, the investment strategies ofSub-Funds as a percentage of the Fund’s net assets were as follows:

STRATEGY WEIGHTINGS	PERCENTAGE
Credit/Distressed		16.1	%
Global Macro		9.0
Non-U.S. Equity Hedge		17.4
Opportunistic		2.6
Relative Value Multi-Strategy		14.7
Sector Hedge		7.6
Special Situations		15.3
U.S. Equity Hedge		10.0
Cash Equivalent and Other Assets less Liabilities		7.3
Total		100.0	%

At September 30, 2019, the Fund’sSub-Funds investments were domiciled as follows:

COUNTRIES	COST		VALUE
Cayman Islands - 46.7%	$	323,267,000	$	345,479,000
United States - 46.0%		291,208,000		339,683,000
Total	$	614,475,000	$	685,162,000

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in three levels listed below:

Level 1 - Unadjusted quoted market prices in active markets for identical investments on the measurement date and on an ongoing basis.

Level 2 - Other observable inputs (e.g., quoted prices in active markets for similar securities, securities valuations based on commonly quoted benchmark interest rates and yield curves, maturities, ratings and/or securities indices).

Level 3 - Significant unobservable inputs (e.g., information about assumptions, including risk, market participants would use in pricing a security).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and other financial instruments, if any. The Fund’s investment in the Goldman Sachs Financial Square Government Fund is valued at its net asset value. All otherSub-Funds’ values were measured using the net asset value per share (or its equivalent) practical expedient and have not been classified in the fair value hierarchy. See Note 7 in the Notes to the Financial Statements for further risk and liquidity information of the Fund’s underlying investments by major category.

The Fund is not able to obtain complete investment holdings details on each of theSub-Funds held within the Fund’s portfolio in order to determine whether the Fund’s proportional share of any investments held by theSub-Funds exceeds 5% of the net assets of the Fund as of September 30, 2019.

ALPHA CORE STRATEGIES FUND8 SEMIANNUAL REPORT

ALPHA CORE STRATEGIES FUND

NOTES TO THE FINANCIAL STATEMENTS SEPTEMBER 30, 2019 (UNAUDITED)

1. ORGANIZATION

Alpha Core Strategies Fund (the “Fund”) is a Delaware statutory trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as aclosed-end, diversified management investment company. The Fund’s investment objective is to achieve attractive risk-adjusted rates of return through investment in a diversified portfolio of assets. The Fund operates as a“Fund-of-Funds” investing, either directly or indirectly, in a group of funds or other pooled investment vehicles (the“Sub-Funds”) managed by investment advisers selected by the Fund’s investment manager. The Fund seeks to provide investors with exposure to alternative investment strategies by investing in diversified markets and instruments.

U.S. investors may invest directly in the Fund. U.S.tax-exempt investors andnon-U.S. investors may not invest directly in the Fund, but rather invest in one of the two following “Feeder Funds,” both of which invest substantially all of their assets in the Fund: (1) Alpha Core Strategies Feeder Fund, Q.P., which is open to U.S.tax-exempt investors andnon-U.S. investors that are both Accredited Investors and Qualified Purchasers (as such terms are defined in Regulation D under the Securities Act of 1933, as amended and Section 2(a)(51) of the 1940 Act, respectively) or (2) Alpha Core Strategies Feeder Fund, which is open to U.S.tax-exempt investors andnon-U.S. investors that are Accredited Investors, but not Qualified Purchasers.

50 South Capital Advisors, LLC (“50 South”) serves as the Fund’s investment manager. 50 South is a wholly owned direct subsidiary of Northern Trust Corporation (“NTC”), and is registered with the U.S. Securities and Exchange Commission as an investment adviser.

The Bank of New York Mellon (“BNYM”) is the Fund’s fund accountant, transfer agent, administrator and custodian.

Northern Trust Securities, Inc. (“NTSI”), a subsidiary of NTC, serves as the placement agent for the Fund.

2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is defined as a diversifiedclosed-end management investment company in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”)2013-08, follows accounting and reporting guidance under FASB Accounting Standards Codification (“ASC”) Topic 946, “Financial Services – Investment Companies”.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and

liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results may differ from those estimates.

A) VALUATION OF SECURITIESInvestments inSub-Funds are valued at fair value, as determined by 50 South, pursuant to delegation from the Board of Trustees of the Fund (the “Board”). The Board has delegated the responsibility of determining the valuation of the Fund’sSub-Funds to the 50 South Pricing Committee for the Funds (the “Pricing Committee”), subject to oversight by the Board. The Pricing Committee consists of representatives from 50 South and Northern Trust Investments, Inc., (“NTI”) as recommended to, and approved by, the Board.

In determining themonth-end fair value of each investment in aSub-Fund, the Pricing Committee considers the estimated net asset value (“NAV”) of suchSub-Fund provided to the Fund by theSub-Fund, or its equivalent, such as ownership interest in partners’ capital or members’ capital of theSub-Fund as of the reporting date as a practical expedient for fair value, as well as any other considerations identified that may increase or decrease such estimated fair value. In addition, eachSub-Fund’s NAV is monitored for conformity with U.S. GAAP through monthly reviews of the values of the underlying investments held by eachSub-Fund (when theSub-Fund’s underlying investments are identified to the Pricing Committee, either directly or through a third-party pricing vendor), through operational due diligence performed prior to investing in aSub-Fund and continually through the review of eachSub-Fund’s audited financial statements. If aSub-Fund’s NAV is not available or aSub-Fund’s NAV is determined not to be reasonable based on the Pricing Committee’s evaluation, the Pricing Committee will make the final determination of the fair value of aSub-Fund. In making its determination, the Pricing Committee is authorized to consider factors that it deems appropriate to the determination of the fair value of theSub-Fund. Such factors may include, but are not limited to, the following: changes in the equity and fixed income markets; type ofSub-Fund (i.e., strategy); current financial position of theSub-Fund; cost of the investment; and news events. Accordingly, because of the inherent uncertainty of these valuations, these estimated fair values may differ significantly from the values that could have been used had a readily available market for the investments existed, and the differences could be material.

50 South continually monitors markets and the investment managers of theSub-Funds. 50 South is responsible for notifying the Pricing Committee if the markets and/or aSub-Fund’s manager’s circumstances relevant to the valuation of the fair valuedSub-Fund change materially.

The Fund’s cash equivalent investment, which is comprised of an investment in Goldman Sachs Financial Square Government Fund, an open-ended investment company, is valued at its NAV.

NOTES TO THE FINANCIAL STATEMENTS  continued

B) CASH AND CASH EQUIVALENTSThe Fund treats all financial instruments with original maturities of three months or less as cash equivalents. Cash and cash equivalents held in the Fund are shown on the accompanying Schedule of Investments.

C) INVESTMENT TRANSACTIONS, INCOME AND EXPENSES Investment transactions are recorded as of the trade date. The Fund determines the gain or loss realized from investment transactions by using an identified cost basis method. Interest income and expenses are recognized on an accrual basis. The Fund does not currently intend to make any income and capital gain distributions.

D) FEES AND EXPENSESThe Fund is responsible for paying administrative and operating expenses. In addition, the Fund is generally responsible for paying the operating expenses, except for certain administrative services, of the Feeder Funds.

The Fund is also responsible for fees payable by theSub-Funds to their respective advisers (collectively, the “Advisory Fees”) in proportion to the Fund’s investments in theSub-Funds. The Advisory Fees will vary, but they will typically consist of a management (asset-based) fee and an incentive fee. Management fees typically range between 1% and 2% of aSub-Fund’s net asset value per year, and incentive fees range between 10% and 35% of theSub-Fund’s net new profits. These Advisory Fees are accounted for in the valuations of theSub-Funds (which are reported in these financial statements net of such fees) and are not included in the Statement of Operations.

E) FEDERAL INCOME TAXESThe Fund operates, and has elected to be treated, as a partnership for federal income tax purposes. Accordingly, no provision for the payment of federal, state or local income taxes has been provided. Each unitholder is individually required to report on its own tax return its distributive share of the Fund’s taxable income or loss.

As of March 31, 2019, the Fund did not have uncertain tax positions that would require financial statement recognition or disclosure. The Fund’s federal tax returns filed for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

3. RELATED PARTY, INVESTMENT

MANAGEMENT AND OTHER AGREEMENTS

As compensation for investment management services, 50 South is entitled to receive a 1.00% per annum fee of the Fund’s NAV, payable quarterly in arrears, calculated as of the last business day of each month. 50 South has agreed to reimburse the Fund for all operating expenses, exclusive of management, administration, custody, transfer agent fees, interest expense andSub-Fund fees and expenses, that exceed 0.50% per annum of the Fund’s NAV. Pursuant to the expense limitation agreement, amounts reimbursed by 50 South are subject to possible recoupment from the Fund in the fiscal year after the year in which such amount was reimbursed if such recoupment can be achieved without

5. INVESTMENT TRANSACTIONS

The Fund had aggregate purchases of $22,275,000 and proceeds from sales ofSub-Funds of $101,268,000 (excluding short-term investments) for the six months ended September 30, 2019.

At September 30, 2019, the estimated cost of investments for federal income tax purposes was $614,475,000. At September 30, 2019, accumulated net unrealized appreciation (depreciation) on investments was $70,687,000 consisting of $85,212,000 gross unrealized appreciation and $14,525,000 gross unrealized depreciation.

6. NET ASSETS

The net assets of the Fund are determined as of the last business day of each calendar month.

7. RISK FACTORS

TheSub-Funds may borrow and may utilize various lines of credit, reverse repurchase agreements, “dollar rolls”, issuance of debt securities, swaps, forward purchases, otheroff-Statement of Assets and Liabilities derivative transactions and other forms of leverage. While leverage presents opportunities for increasing total return, it has the effect of potentially increasing losses as well. If income and appreciation on investments made with borrowed funds are less than the cost of the leverage, the value of aSub-Fund’s net assets will decrease. Accordingly, any event which adversely affects the value of an investment by aSub-Fund would be magnified to the extent leverage is employed. The cumulative effect of the use of leverage in a market that moves adversely to a leveraged investment could result in a substantial loss which would be greater than if leverage were not used. In periods of extreme market volatility, the need to sell assets in a declining market can cause even greater losses, as prices may be artificially depressed. Generally, most leveraged transactions involve the posting of collateral. Increases in the amount of margin that aSub-Fund is required to post could result in a disposition ofSub-Fund assets at times and prices which could be disadvantageous to theSub-Fund and could result in substantial losses. Creditors’ claims may be senior to the rights of unitholders in theSub-Fund.

(a) Event Driven– The managers in this category seek to profit from opportunities arising from specific situations affecting individual stocks or unique circumstances in a particular industry, sector or market. These market participants typically specialize in certain sectors of the Event Driven space, utilizing unique skills or knowledge of bankruptcy law, specific market events, or otherwise.Sub-strategies in this category include Credit/Distressed and Special Situations. The fair values of the investments in this category have been estimated using the NAV per share (or its equivalent) of the investments. Investments representing approximately 76.53% of the fair value of investments in this category cannot be immediately redeemed because the investments include investor-level gate restrictions. These gates are for twelve months and do not allow for full redemptions.

(b) Global Macro– The managers in this category employ strategies directed more heavily towards the ebbs and flows of markets on a larger scale, as opposed to focusing on the relative attractiveness between individual securities. Managers seek to identify the direction that certain markets will follow over various time periods and position their portfolios accordingly.Sub-strategies in this category include Global Macro. The fair values of the investments in this category have been estimated using the NAV per share (or its equivalent) of the investments. One investment representing approximately 37.66% of the fair value of investments in this category cannot be immediately redeemed because the investment includes investor-level gate restrictions. The gate is for eleven months and does not allow for full redemptions.

(c) Hedged Equity– The managers in this category seek to identify and select equity securities that will rise in price on the long side and those that will fall in price on the short side. Equity securities make up the large bulk of their underlying exposure. Net exposure ranges from zero to 100%, while gross exposure can be 200% or more.Sub-strategies in this category includeNon-U.S. Equity Hedge, Sector Hedge, and U.S. Equity Hedge. The fair values of the investments in this category have been estimated using the NAV per share (or its equivalent) of the investments. Investments representing approximately 16.98% of the fair value of investments in this category cannot be immediately redeemed because the investments include investor-level gate restrictions. These gates range

from six months to twelve months and do not allow for full redemptions. For one investment representing approximately 0.02% of the fair value of investments in this category, no redemptions are currently permitted. The Fund is not able to estimate when the redemption restriction might lapse.

(d) Opportunistic– The managers in this category seek to produce differentiated return streams often with lower fees by offering access to specific trades, based on high conviction ideas, directly to investors. The specific trades that could fall under any of the other vehicles may offer more frequent liquidity.Sub-strategies in this category include Opportunistic. The fair values of the investments in this category have been estimated using the NAV per share (or its equivalent) of the investments. For two investments representing approximately 20.16% of the fair value of investments in this category, no redemptions are currently permitted. The manager returns capital after realization of the investments.

(e) Relative Value– The managers in this category seek to deliver alpha without subjecting themselves to or relying on beta or general market exposure for performance. They seek to do this by identifying and exploiting various arbitrage opportunities between and among related groups of securities, with the expectation that returns will have a low correlation to the markets in which those securities trade.Sub-strategies in this category include Relative Value Multi-Strategy. The fair values of the investments in this category have been estimated using the NAV per share (or its equivalent) of the investments. One investment representing approximately 24.98% of the fair value of investments in this category cannot be immediately redeemed because the investment includes investor-level gate restrictions. The gate is for twelve months and does not allow for full redemptions. For one investment representing approximately 0.00% of the fair value of investments in this category, no redemptions are currently permitted. The Fund is not able to estimate when the redemption restriction might lapse.
