<p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">1. Description of Business</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Epsilon Energy Ltd. (the “Company” or “Epsilon” or “we”) was incorporated under the laws of the Province of Alberta, Canada on March 14, 2005. On October 24, 2007, the Company became a publicly traded entity trading on the Toronto Stock Exchange (“TSX”) in Canada. On February 14, 2019, Epsilon’s registration statement on Form 10 was declared effective by the United States Securities and Exchange Commission and on February 19, 2019, we began trading in the United States on the NASDAQ Global Market under the trading symbol “EPSN.” Effective as of the close of trading on March 15, 2019, Epsilon voluntarily delisted its common shares from the TSX. The Company is engaged in the acquisition, development, gathering and production of primarily natural gas reserves in the United States.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">Recent Developments</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On March 10, 2021, Epsilon filed a complaint against Chesapeake Appalachia, LLC (“Chesapeake”) in the United States District Court for the Middle District of Pennsylvania, Scranton, Pennsylvania. Epsilon claims that Chesapeake has breached a settlement agreement and several operating agreements (“JOAs”) to which Epsilon and Chesapeake are parties. Epsilon asserts that Chesapeake has failed to cooperate with Epsilon’s efforts to develop resources in the Auburn Development, located in North-Central Pennsylvania, as required under both the settlement agreement and JOAs. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Epsilon requested a preliminary injunction but was unsuccessful in obtaining that injunction. Epsilon filed a motion to amend its original Complaint. Chesapeake opposed. The Court ruled in Epsilon’s favor and allowed Epsilon’s amendment. Chesapeake moved to dismiss the amended Complaint. The Court granted the motion to dismiss without prejudice to Epsilon’s right to file a new lawsuit based on new proposals made after the Court’s decision. Epsilon filed a motion for reconsideration of that decision. The motion for reconsideration was fully briefed in November 2021. Epsilon filed a notice of additional evidence to the motion for reconsideration on January 4, 2022. The motion for reconsideration was denied on January 18, 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">Epsilon filed a notice of appeal on February 15, 2022 challenging both the motion to dismiss and motion for reconsideration decisions. Chesapeake filed a cross-appeal on March 1, 2022. A briefing schedule has not yet been set but a decision on the appeal is expected in the fourth quarter of 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">On February 25, 2022, the Board of Directors approved a quarterly cash dividend of $0.0625 per common share, payable on March 31, 2022, to shareholders of record at the close of business on March 8, 2022. With the initiation of a cash dividend, Epsilon intends to pay regular quarterly dividends, with future dividend payments subject to quarterly review and approval by its Board of Directors. At this quarterly dividend rate, the annual dividend rate for the fiscal year 2022 is $0.25 per share.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">The Board of Directors also authorized the repurchase of up to 1,183,410 of the outstanding common shares, representing 5% of the outstanding common shares of Epsilon, for an aggregate purchase price of not more than US $8.0 million, pursuant to a normal course issuer bid, during the one-year period commencing on March 8, 2022. The program will end on March 7, 2023 unless the maximum amount of common shares is purchased before then or Epsilon provides earlier notice of termination.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;"></span></p> | |

The most significant estimates pertain to proved natural gas reserves and related cash flow estimates used in impairment tests of oil and natural gas and gathering system properties, asset retirement obligations, accrued natural gas and oil revenues and operating expenses, accrued gathering system revenues and operating expenses, as well as the valuation of commodity derivative instruments. Actual results could differ from those estimates.</p> | |

Exposure to credit risk associated with these instruments is controlled by (i) placing assets and other financial interests with credit-worthy financial institutions, (ii) maintaining policies over credit extension that include the evaluation of customers’ financial condition and monitoring paying history, although the Company does not have collateral requirements and (iii) netting derivative assets and liabilities for counterparties with a legal right of offset. At December 31, 2021 and 2020, the cash and cash equivalents were primarily concentrated in two financial institutions, one in Canada and one in the US. The Company periodically assesses the financial condition of these institutions and believe that any possible credit risk is minimal.</p> | |

As a result of this geographic concentration, we may be disproportionately exposed to the effect of regional supply and demand factors, delays or interruptions of production from wells in this area caused by governmental regulation, processing or transportation capacity constraints, market limitations, weather events or interruption of the processing or transportation of crude oil or natural gas. </p> | |
