Forward-Looking Information

This current report on Form 8-K contains forward-looking statements, based on numerous assumptions and subject to risks and uncertainties. Although the Company believes that the forward-looking statements are reasonable, it does not and cannot give any assurance that its beliefs and expectations will prove to be correct. Many factors could significantly affect the Company’s operations and cause the Company’s actual results to differ substantially from the Company’s expectations. Those factors include, but are not limited to: (i) general economic and construction business conditions; (ii) customer acceptance of the Company’s products; (iii) relationships with key customers; (iv) materials and manufacturing costs; (v) the financial condition of customers, competitors and suppliers; (vi) technological developments; (vii) increased competition; (viii) changes in capital and credit market conditions; (ix) governmental and business conditions in countries where the Company’s products are manufactured and sold; (x) changes in trade regulations; (xi) the effect of acquisition activity; (xii) changes in the Company’s plans, strategies, objectives, expectations or intentions; and (xiii) other risks and uncertainties indicated from time to time in the Company’s filings with the U.S. Securities and Exchange Commission. Actual results might differ materially from results suggested by any forward-looking statements in this report. The Company does not have an obligation to publicly update any forward-looking statements, whether as a result of the receipt of new information, the occurrence of future events or otherwise.

On November 4, 2011, The Hillman Companies, Inc. (“we”, “us”, “our”, “Hillman”, or the “Company”) and The Hillman Group, Inc. (“HGI”), pursuant to their existing Credit Agreement, dated as of May 28, 2010 (as amended by Amendment No. 1 to Credit Agreement dated as of December 22, 2010 and Amendment No. 2 to Credit Agreement dated as of April 18, 2011), among OHCP HM Acquisition Corp, Hillman and HGI, the banks and other lending institutions from time to time party thereto, and Barclays Bank PLC, as Administrative Agent, Issuing Lender and Swingline Lender (the “Credit Agreement”) entered into a Joinder Agreement dated as of November 4, 2011 by and among Barclays Bank PLC, as a New Lender, Hillman, HGI, Barclays Bank PLC, as Administrative Agent and, solely for purposes of Sections 17(a) and 17(b) thereof, each other Credit Party party thereto (the “Incremental Facility”). The Incremental Facility increased the aggregate term loan commitments available to HGI under the Credit Agreement by $30 million, such that the aggregate principal amount of commitments under the Credit Agreement after giving effect to the Incremental Facility are $350 million ($320 million aggregate principal amount of term loan commitments and up to $30 million aggregate principal amount of revolving commitments). The $30 million in proceeds from the Incremental Facility will be funded to HGI on November 10, 2011 subject to customary closing conditions, all of which the Company anticipates will be satisfied. It is currently expected that the proceeds from the Incremental Facility will be used for general corporate purposes. The above summary of the Incremental Facility is qualified in its entirety by reference to the complete terms and provisions of the Incremental Facility filed herewith as Exhibit 99.1.

On November 7, 2011, the Company provided the following guidance on its results for the quarter ended September 30, 2011 in connection with the announcement of the Company’s entry into the Incremental Facility.

For the quarter ended September 30, 2011, based on information currently available to the Company, the Company expects net sales to be between $137.0 million and $138.0 million, income from operations to be between $14.0 million and $15.0 million, and Adjusted EBITDA (as defined below) to be between $26.5 million and $27.5 million. After giving pro forma effect to the Company’s previous acquisition of TAGWORKS, LLC (“TagWorks”) as if it had occurred on January 1, 2011, the Company estimates net sales for the nine months ended September 30, 2011 to be between $387.1 million and $388.1 million and Adjusted EBITDA to be between $70.6 million and $71.6 million.

Below is a reconciliation of net sales to Adjusted EBITDA and Pro Forma Adjusted EBITDA, for the periods indicated:

NOTES:

The preliminary financial data set forth in this section has been prepared by, and is the responsibility of, our management. The foregoing information and estimates have not been compiled or examined by our independent auditors and they are subject to revision as we prepare our financial statements as of and for the quarter and nine months ended September 30, 2011, including all disclosures required by GAAP, and as our auditors conduct their audit of these financial statements. Because we have not completed our normal quarterly closing and review procedures for the quarter ended September 30, 2011, and subsequent events may occur that require adjustments to these results, there can be no assurance that the final results for the quarter and nine months ended September 30, 2011 will not differ materially from these estimates. These estimates should not be viewed as a substitute for full financial statements prepared in accordance with U.S. GAAP or as a measure of performance. In addition, these estimated results of operations for the quarter and the nine months ended September 30, 2011 are not necessarily indicative of the results to be achieved for any future period. See “Forward-Looking Information.” Amounts presented in this Form 8-K have been rounded to the amounts shown for convenience of presentation.

The information under Item 2.02 of this Form 8-K is being furnished under Item 2.02. Such information shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to
