of the Company's common stock, subject to restrictions, pursuant to the Company&rsquo;s 2011 Equity Incentive Plan (the &quot;Plan&quot;).
Such error, which is described below, is reflected in the Company's (i) consolidated financial statements for the period ended

On April 11, 2012, Management of Sigma Labs,
Inc. ("we," "us," "our" or the "Company"), in connection with the preparation of
our financial statements for the year ended December 31, 2011, identified an error related to our accounting for certain issuances
of the Company's common stock, subject to restrictions, pursuant to the Company's 2011 Equity Incentive Plan (the "Plan").
Such error, which is described below, is reflected in the Company's (i) consolidated financial statements for the period ended
June 30, 2011 included in the Company's Form 10-Q that was filed on August 12, 2011 (the "June 2011 Financial Statements"),
and (ii) consolidated financial statements for the period ended September 30, 2011 included in the Company's Form 10-Q that was
filed on November 14, 2011 (the "September 2011 Financial Statements").
As a result of the foregoing error, our
management concluded that the June 2011 Financial Statements and the September 2011 Financial Statements should no longer be relied
upon. During April 2011, the Company issued an aggregate of 20,000,000 shares of Company common stock, subject to restrictions,
pursuant to the Plan and recorded an expense of $400,000 in the June 2011 Financial Statements and in the September 2011 Financial

2011 and September 30, 2011, resulting in an overstatements of non-cash expenses of $303,000. Thus, our net loss reported was also
overstated by $303,000.
Our consolidated financial statements for

of December 31, 2011. Our executive officers have discussed the matters described herein with Pritchett, Siler & Hardy, P.C.,
