PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Tangoe, Inc. (the “Company”) has determined that it is unable to file its Annual Report on Form 10-K for the year ended December 31, 2015 within the prescribed time period without unreasonable effort or expense for the following reason.

As reported in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on March 7, 2016, the Board of Directors of the Company, upon the recommendation of the Company’s Audit Committee, determined that the Company will restate its financial statements for the years 2013 and 2014, all quarters therein, and the first three quarters of 2015. The Company has concluded that it made errors in recognizing revenue, primarily from business activities that are ancillary to the Company’s core business. A majority of the errors relate to non-recurring revenue, including, for example, non-recurring revenue from strategic consulting and bill audit services with contingent fee arrangements. As a result of these corrections, the Company is revising its revenue recognition policies for several categories of revenue.

Because the Company is in the process of restating its financial statements as described above, the Company has not been able to complete the financial statements required to be included in its Annual Report on Form 10-K for the year ended December 31, 2015 and, accordingly, is unable to file the Form 10-K within the prescribed time period. Although the Company cannot at this time estimate when it will complete the restatement and file its restated financial statements and its Form 10-K for the year ended December 31, 2015, it is diligently pursuing completion of the restatement and intends to file the Form 10-K as soon as reasonably practicable.

Persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB control number.

PART IV — OTHER INFORMATION

(1)	Name and telephone number of person to contact in regard to this notification
	Gary R. Martino	(203)	859-9300
	(Name)	(Area Code)	(Telephone Number)

(2)	Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

			x Yes o No

(3)	Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

			x Yes o No

	If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. As reported in the Company’s Current Report on Form 8-K filed with the SEC on March 7, 2016, the Company estimates that, for the full periods being restated, at least $17.1 million of previously recognized revenue will be affected, against total revenue under review of approximately $70 million and previously reported total revenue of $565.9 million. The Company expects that operating income will be adjusted substantially in line with revenue adjustments. The Company also expects that the impact, if any, on operating cash flow for the periods under review will be minimal. Because the Company has not yet fully completed its review, the expected financial impact of the restatement described above is preliminary and subject to change. Forward-looking statements Except for statements of historical fact, the matters discussed in this Form 12b-25 are “forward-looking statements” within the meaning of the applicable securities laws and regulations. The words “estimates”, “expects” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements, including statements regarding the Company’s intent to restate its prior financial statements and the estimated adjustments of the restated financials, involve risks and uncertainties that may cause actual results to differ materially from those stated here. Factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, the risk that additional information may arise from the Company’s and its Audit Committee’s internal review, the risk that the process of preparing and auditing the restated financial statements or other subsequent events would require the Company to make additional adjustments and the time and effort required to complete the restatement of its financial statements, as well as other risks described more fully in the Company’s filings with the SEC. Forward-looking statements reflect management’s analysis as of the date hereof. The Company does not undertake to revise these statements to reflect subsequent developments.
