We also grew segment Adjusted EBITDA while lapping the record 2020 U.S. fire season.” Mr. Goldberg added “The 2021 fourth quarter experienced very limited fire activity, and our Fire Safety results were down period-over-period. Fluctuations based on the intensity of the fire season in a given quarter is a feature of our Fire Safety business, and can be especially pronounced in the much smaller fourth and first quarters, as evidenced in 2021 fourth quarter.” Mr. Goldberg concluded “We’re very optimistic about our business. Assuming a normalized 2022 fire season, and incorporating our best assumptions around other elements of our business, we expect consolidated 2022 Adjusted EBITDA growth consistent with, and perhaps above, our long-term framework of mid-teens growth.”

Our specialized equipment includes airbase retardant storage, mixing, and delivery equipment; mobile retardant bases; retardant ground application units; mobile foam equipment; and equipment that we custom design and manufacture to meet specific customer needs.

The computation of adjusted EBITDA is defined as net income plus income tax expense, net interest and other financing expenses, and depreciation and amortization, adjusted on a consistent basis for certain non-recurring, unusual or non-operational items in a balanced manner and on a segment basis. These items include (i) expenses related to the Business Combination, (ii) founder advisory fee expenses, (iii) stock compensation expense (iv) non-cash impact of purchase accounting on the cost of inventory sold (v) contingent future payment related to an acquired business (vi) management fees related to the services provided by SK Capital Partners IV-A, L.P. and SK Capital Partners IV-B, L.P (collectively, the "Sponsor") when acting in a management capacity and (vi) unrealized foreign currency loss (gain). To supplement the Company's consolidated financial statements presented in accordance with U.S. GAAP, Perimeter is providing a summary, wherein, the Successor Period and the 2021 Predecessor are combined (“S/P Combined”), to show the computations of adjusted EBITDA, and reconciliations from U.S. GAAP income (loss) before income taxes, taking into account certain charges and gains that were recognized during the periods presented. The Corporate category includes unallocated costs related to our corporate headquarter activities.
